The food processor has the following disadvantages: on one hand, the food processor comprises a plurality of food processing cups, which is inconvenient for the food processor to store; on the other hand, when switching cooking machine function, the user need carry out the dismouting to different cooking cups, leads to cooking machine's operation complicacy, inconvenient user's operation.

The cooking machine of this embodiment compares with above-mentioned traditional cooking machine, additionally increases clutch mechanism 4 and separation and reunion actuating mechanism 9, and the cooking machine of this embodiment passes through clutch mechanism 4's output and switches at primary importance and second position, just can realize the switching of rabbling mechanism high rotational speed and low rotational speed in the cup 200, and the user need not to change different cup 200, just can make cup 200 carry out different functions. On one hand, the user does not need to disassemble and assemble the cup body 200, so that the operation of the food processor is simple and convenient; on the other hand, because the cooking machine only needs a cup 200, the storage space of the cooking machine can be saved.

Brushless digital motor or series excited machine can be chooseed for use to traditional cooking machine's power unit, and brushless digital motor not only can realize the output of the high moment of torsion of high rotational speed and can also realize the output of the high moment of torsion of low rotational speed, so brushless digital motor can use in the cooking machine of high rotational speed output and the cooking machine of low rotational speed output, but brushless digital motor's cost ratio is higher, causes the cooking machine with high costs. Although the cost of the series motor is low, the series motor can only be used in a food processor with high rotating speed output generally because the torque (0.2 Nm-1.36 Nm) output by the series motor when the series motor outputs low rotating speed (160 r/min-1280 r/min) is small, and the small torque can not meet the normal use of the food processor. Specifically, the rotating speed and the torque output by the series motor are both regulated through voltage, when the voltage of the series motor is low voltage (2V-8.8V), the series motor outputs low rotating speed (160 r/min-1280 r/min) and low torque (0.2 Nm-1.36 Nm), the driving force of the lower torque is too small, normal use of the food processor cannot be met, and therefore the output of low rotating speed and high torque cannot be realized by utilizing the traditional low-cost series motor.

In order to solve the above problem, as shown in fig. 3, the main input terminal 4111 and the high rotation speed output terminal 4112 are coaxially arranged to form the main shaft 411, the power mechanism 3 is a series motor, and the output terminal of the series motor is in transmission connection with the main input terminal 4111. When high voltage (50V-220V) is applied to the series motor, the speed reducing component 41 can reduce the speed of the high rotating speed (4000 r/min-32000 r/min) output by the series motor, so that the low rotating speed output end 412 outputs the low rotating speed (160 r/min-1280 r/min), and because the high voltage (50V-220V) is applied to the series motor, the series motor outputs the high torque (5 Nm-34 Nm), while the speed reducing component 41 does not change the high torque (5 Nm-34 Nm) and enables the low rotating speed output end 412 to output the high torque (5 Nm-34 Nm), so that the low rotating speed output end 412 can output the high torque (5 Nm-34 Nm) of the low rotating speed (160 r/min-1280 r/min) to the stirring mechanism, and the stirring mechanism can output the low rotating speed and high torque to meet the normal use of the food processor. Because the series motor is low in cost, the food processor provided by the invention is low in cost and can realize the output of low rotating speed and high torque.

The speed reduction assembly 41 of the present embodiment is a planetary speed reduction assembly that operates smoothly, produces little noise, and is priced in the market. To elaborate the structure of the planetary reduction assembly, as shown in fig. 4 to 7, the planetary reduction assembly includes a main shaft 411, a low rotation speed output end 412, a sun gear 413, planet gears 414, a ring gear 415 and a planet carrier 416, the main shaft 411 includes a main input end 4111 and a high rotation speed output end 4112, wherein the main shaft 411 and the sun gear 413 are coaxially arranged, the three planet gears 414 are arranged around the outer periphery of the sun gear 413, the upper surface and the lower surface of the planet gears 414 are respectively provided with one planet carrier 416, each planet gear 414 is rotatably connected with the planet carrier 416, the low rotation speed output end 412 is arranged on the planet carrier 416 located above, and the outer peripheral rings of the three planet gears 414 are provided with the ring gear 415. As shown in fig. 6 and 7, when the main shaft 411 rotates clockwise at a high rotation speed, the sun gear 413 drives the planetary gear 414 combined with the planet carrier 416 to rotate, the planetary gear 414 rotates counterclockwise and rotates clockwise around the sun gear 413, the planet carrier 416 rotates clockwise, the planet carrier 416 drives the low rotation speed output end 412 thereon to rotate at a low rotation speed, and the high rotation speed output end 4112 on the main shaft 411 rotates at a high rotation speed. The first transmission ratio i1 of the planetary reduction assembly can be adjusted by adjusting the respective diameters and the numbers of teeth of the sun gear 413, the planet gear 414 and the ring gear 415, the rotation speed of the low rotation speed output end 412 of the planetary reduction assembly is 1/i1 of the rotation speed of the main shaft 411, and the first transmission ratio i1 of the planetary reduction assembly of the embodiment is preferably 5-8, and the case is preferably 6.25.

As shown in fig. 2 and 8, in order to realize the parallel arrangement and the transmission connection of the clutch mechanism 4 and the power mechanism 3, the food processor further comprises a first transmission mechanism 7, and the clutch mechanism 4 and the power mechanism 3 are in transmission connection through the first transmission mechanism 7. Specifically, as shown in fig. 8 and 9, the first transmission mechanism 7 includes a first transmission wheel 71, a second transmission wheel 72, and an endless transmission belt 73, the first transmission wheel 71 is provided at an input end of the clutch mechanism 4, the second transmission wheel 72 is provided at an output end of the power mechanism 3, and the first transmission wheel 71 and the second transmission wheel 72 together tension the endless transmission belt 73. The diameter ratio of the first transmission wheel 71 to the second transmission wheel 72 is adjusted, so that the adjustment of a second transmission ratio i2 (the diameter ratio of the first transmission wheel 71 to the second transmission wheel 72) of the first transmission mechanism 7 is realized, the adjustment of the rotating speed of the spindle 411 is further realized, the second transmission ratio i2 is preferably 3-5, on one hand, the speed reduction effect on the spindle 411 can be realized, on the other hand, the second transmission ratio i2 is moderate, the vibration of the annular transmission belt 73 can be avoided, and when the second transmission ratio i2 is preferably 4, the effect is better.

In addition, the speed regulation ranges of the upper speed regulation limit and the lower speed regulation limit of the driven series excited motor are small and have the problem of mutual restriction, and the upper speed regulation limit is improved, and the lower speed regulation limit is also improved. Specifically, the brushless motor has a rotating speed of 40r/min to 10000r/min, a wide speed regulation range, and high cost. The speed regulation range of the series excited motor is narrow, and if the upper speed regulation limit of the series excited motor is adjusted upwards, the lower speed regulation limit of the series excited motor is also adjusted upwards, so that the series excited motor cannot realize low rotating speed; similarly, if the lower limit of the speed regulation of the slave series-excited motor is adjusted downwards, the upper limit of the speed regulation of the series-excited motor is also adjusted downwards correspondingly, and the series-excited motor cannot realize the high-rotation speed. When the first transmission ratio i1 is 6.25, the second transmission ratio i2 is 4, and the rotation speed of the series motor is 4000 r/min-32000 r/min, the rotation speed of the main shaft 411 is 1000 r/min-8000 r/min, and the rotation speed which can be output by the low rotation speed output end 412 of the speed reducing component 41 is 160 r/min-1280 r/min, so that the speed regulating range of 160 r/min-8000 r/min can be realized by applying the series motor, and the cost is low.

In the design process of the pulley assembly, once the second transmission ratio i2 is determined, the center-to-center distance between the first driving wheel 71 and the second driving wheel 72 can be determined in order to realize the predetermined second transmission ratio i2, and the center-to-center distance between the first driving wheel 71 and the second driving wheel 72 is not too small in general, so that the pulley assembly occupies a large space in the horizontal direction. As shown in fig. 9, the clutch driving mechanism 9 is disposed in the space surrounded by the first driving wheel 71, the second driving wheel 72 and the annular transmission belt 73, the clutch driving mechanism 9 can reasonably and fully utilize the space formed among the first driving wheel 71, the second driving wheel 72 and the annular transmission belt 73, thereby achieving the purpose that the clutch driving mechanism 9 fully utilizes the inner space of the housing 1, although the clutch driving mechanism 9 is added, the size of the housing 1 in the horizontal direction is not increased, the design of the food processor in the horizontal direction with a smaller size can be realized, and the volume of the food processor in this embodiment is smaller.

In order to realize the quick installation of cooking machine, as shown in fig. 2, the cooking machine further comprises an installation plate 2, the clutch mechanism 4 and the power mechanism 3 are both installed on the installation plate 2, and the installation plate 2 is installed on the housing 1. The user can install power unit 3, speed reduction unit 41 and clutch pack 42 on mounting panel 2 earlier when installing the cooking machine at first, and install mounting panel 2 that will integrate power unit 3, speed reduction unit 41 and clutch pack 42 in casing 1 again, improves the installation effectiveness of cooking machine for the cooking machine is more accurate for spare part equipment. The power mechanism 3 in this embodiment is a motor, and generally, the larger the power is, the larger the weight is, and in order to achieve better driving of the output mechanism 6, the motor in this embodiment is heavier, and the motor is heavier than the single speed reduction assembly 41 or the single clutch assembly 42. Because the sum of the weights of the speed reducing assembly 41 and the clutch assembly 42 is approximately the same as the weight of the power mechanism 3, the clutch mechanism 4 and the power mechanism 3 are arranged on the mounting plate 2 side by side, so that all parts of the mounting plate 2 are relatively balanced in stress, and on one hand, the mounting plate 2 can be prevented from being deformed due to overlarge stress on the local position of the mounting plate 2; on the other hand, can avoid mounting panel 2 to take place to warp towards the great direction of atress, can prevent that the relative position between the inside each spare part of cooking machine from changing, guarantee that the inside each other cooperation of each spare part of cooking machine can be accurate and normal going on, guarantee the normal clear of cooking machine function, avoid the cooking machine trouble that uses for a long time.

In addition, as shown in fig. 8, since the power mechanism 3 has a large weight, the power mechanism 3 is mounted on the upper side of the mounting plate 2, and the mounting plate 2 can provide a good supporting function for the power mechanism 3, so that the power mechanism 3 can be effectively prevented from falling off the mounting plate 2, and the normal operation of the food processor can be realized.

In the working process of the food processor, the power mechanism 3, the speed reduction assembly 41 and the clutch assembly 42 vibrate, so that the operation experience of a user is influenced. In order to solve the above problem, as shown in fig. 2, the food processer further includes a damping mechanism 5, the damping mechanism 5 is disposed between the mounting plate 2 and the housing 1, and the damping mechanism 5 can effectively absorb the vibration generated by the power mechanism 3, the speed reduction assembly 41 and the clutch assembly 42, so that the noise of the food processer during use can be effectively reduced, and the use experience of the user is improved. Note that the power mechanism 3, the reduction assembly 41, and the clutch assembly 42 are mounted on the mounting plate 2, which means that the power mechanism 3, the reduction assembly 41, and the clutch assembly 42 are integrated with the mounting plate 2, and the power mechanism 3, the reduction assembly 41, and the clutch assembly 42 are not limited to being located above the mounting plate 2, but include the case where the power mechanism 3, the reduction assembly 41, and the clutch assembly 42 are located below the mounting plate 2.

Preferably, the damping mechanism 5 in this embodiment may be an elastic pad, which can achieve a good damping effect on the integrated structure and a stable supporting effect on the mounting plate 2. The damping mechanism 5 in this embodiment may also be a spring, which can provide a larger elastic restoring force than the elastic pad, and the damping effect is better.

The power mechanism 3, the speed reduction assembly 41 and the clutch assembly 42 have heavy weights, and if the mounting plate 2 on which the power mechanism 3, the speed reduction assembly 41 and the clutch assembly 42 are mounted is mounted on the upper case 14, the mounting plate 2 is easily separated from the upper case 14 under the gravity of the power mechanism 3, the speed reduction assembly 41 and the clutch assembly 42, so that the machine body 100 cannot normally operate. In order to solve the above problem, as shown in fig. 2, a plurality of support columns 11 are arranged on the bottom case 12, the mounting plate 2 on which the power mechanism 3, the speed reduction assembly 41 and the clutch assembly 42 are mounted is fixed on the support columns 11, and the support columns 11 play a better supporting role for the mounting plate 2 on which the power mechanism 3, the speed reduction assembly 41 and the clutch assembly 42 are mounted, so that the mounting plate 2 and the housing 1 can be effectively prevented from loosening, and the normal operation of the machine body 100 is ensured.

The specific structure of the support post 11 will now be described with reference to fig. 2: support column 11 is the echelonment, be provided with a damping mechanism 5 on the ladder face of every support column 11, a plurality of damping mechanisms 5 support mounting panel 2 jointly, the cooking machine still includes a plurality of fixed subassemblies, every support column 11 is provided with a fixed subassembly, fixed subassembly and the common centre gripping mounting panel 2 of support column 2 and damping mechanism 5, can realize casing 1 through above-mentioned structure, damping mechanism 5 and the fast assembly of mounting panel 2, can improve casing 1, damping mechanism 5 and mounting panel 2's packaging efficiency. Specifically, the topmost section of the support column 11 is a threaded column, the fixing component is a nut, and the nut is screwed on the threaded column to realize the relatively stable fixation of the shell 1, the vibration damping mechanism 5 and the mounting plate 2.

Since the power mechanism 3 generates vibration during operation, the vibration is transmitted to the mounting plate 2. If the clutch assembly 42 is installed on the speed reducing assembly 41 and then the speed reducing assembly 41 is installed on the mounting plate 2, the output mechanism 6 in transmission connection with the clutch assembly 42 is vertically spaced from the mounting plate 2 by a larger distance, and the position where the clutch assembly 42 is matched with the clutch driving mechanism 9 is also vertically spaced from the mounting plate 2 by a larger distance. The vibration of mounting panel 2 will be to leading to clutching mechanism 4 to take place the skew of certain angle (alpha angle) than its initial mounting position, because output mechanism 6 is great along the distance of vertical direction apart from mounting panel 2, will lead to output mechanism 6 skew distance great in the horizontal direction, lead to output mechanism 6 can't normally with power transmission to rabbling mechanism to influence the processing of rabbling mechanism edible material in to cup 200. In addition, because the clutch assembly 42 is great from the distance of mounting panel 2 along vertical direction with clutch actuating mechanism 9 matched with position, will lead to clutch assembly 42 and clutch actuating mechanism 9 matched with position great distance of skew on the horizontal direction, influence the transmission precision between clutch assembly 42 and the clutch actuating mechanism 9, can't realize clutch actuating mechanism 9 to clutch assembly 42's accurate control, can't realize the accurate switching of cooking machine rotational speed.

In order to solve the above problem, as shown in fig. 2 and 8, the decelerating component 41 and the clutch component 42 of the present embodiment are distributed along the vertical direction and located at the upper and lower sides of the mounting plate 2, compared with the food processor described in the previous paragraph, the distance between the clutch component 42 and the mounting plate 2 along the vertical direction is greatly reduced, even if the clutch component 41 is deviated by an angle α from its initial position, the deviation distance of the output mechanism 6 in the horizontal direction is much smaller than the deviation of the output mechanism 6 of the food processor described in the previous paragraph, so that the output mechanism 6 transmits power to the stirring mechanism well, and the stirring mechanism is ensured to process food in the cup body 200 well. In addition, compare with the aforementioned cooking machine structure, the clutch assembly 42 of this embodiment is less apart from the distance of mounting panel 2 along vertical direction with clutch drive mechanism 9 matched with position for the distance of clutch assembly 42 and clutch drive mechanism 9 matched with position skew in the horizontal direction reduces greatly, can guarantee the transmission precision between clutch assembly 42 and the clutch drive mechanism 9, realize clutch drive mechanism 9 to clutch assembly 42's accurate control, realize the accurate switching of cooking machine rotational speed.

If the clutch assembly 42 is mounted on the speed reducing assembly 41 and then the clutch assembly 42 is mounted on the mounting plate 2, the first driving wheel 71 is spaced apart from the mounting plate 2 in the vertical direction. The vibration of the mounting plate 2 causes the clutch mechanism 4 to deviate by a certain angle (angle beta) compared with the initial mounting position, because the distance between the first driving wheel 71 and the mounting plate 2 along the vertical direction is large, the deviation distance of the first driving wheel 71 in the horizontal direction is large, the transmission precision of the first driving mechanism 7 is greatly reduced, when the mounting plate 2 vibrates too much, the first driving wheel 71 is separated from the annular driving belt 73, the power of the power mechanism 3 cannot be transmitted to the clutch mechanism 4, the stirring mechanism cannot work, and the food processor cannot be normally used.

In order to solve the above problems, as shown in fig. 2 and 8, the decelerating assembly 41 and the clutch assembly 42 of the present embodiment are distributed along the vertical direction and located at the upper and lower sides of the mounting plate 2, compared with the food processor described in the previous paragraph, the food processor with this structure has a structure in which the distance between the decelerating assembly 41 and the first driving wheel 71 along the vertical direction is greatly reduced, and even if the first driving wheel 71 has an angle β compared with its initial position, the offset distance of the first driving wheel 71 in the horizontal direction is also small, so that the transmission accuracy of the first driving mechanism 7 can be ensured, the first driving wheel 71 is prevented from being disengaged from the annular driving belt 73, the power of the power mechanism 3 is ensured to be transmitted to the clutch mechanism 4, the normal operation of the stirring mechanism is realized, and the normal use of the food processor is ensured.

As shown in fig. 10 and 12, the mounting plate 2 is in a Z shape, the mounting plate 2 includes a first support plate 21, a connection plate 22 and a second support plate 23 connected to each other, the first support plate 21 is higher than the second support plate 23, the clutch assembly 42 and the speed reduction assembly 41 are located at upper and lower sides of the first support plate 21, the power mechanism 3 is mounted at an upper side of the second support plate 23, a top end of the output mechanism 6 is flush with a top end of the power mechanism 3, and an input end of the speed reduction assembly 41 is flush with an output end of the power mechanism 3. Thereby realize that the whole that clutch mechanism 4 and power unit 3 on mounting panel 2 formed does not have obvious arch in vertical direction, if whole have the arch will lead to the inside partial space of casing 1 to be the strip and can't by make full use of, whole no obvious arch makes clutch mechanism 4 and power unit 3 arrange compacter in vertical direction, can make overall structure effectively utilize the finite space in the casing 1, avoid the waste of unnecessary casing 1 inner space, effectively reduce the volume of cooking machine. Wherein, output mechanism 6's top is transmission case 61, and the input of rabbling mechanism is pegged graft in transmission case 61 to can realize output mechanism 6 with power output to the effect of rabbling mechanism.

In addition, the first transmission mechanism 7 of this embodiment is a belt pulley assembly, and since the input end of the speed reduction assembly 41 is flush with the output end of the power mechanism 3, the effect of connecting the first transmission mechanism 7 with the input end of the speed reduction assembly 41 and the output end of the power mechanism 3 quickly and accurately can be achieved, and the installation efficiency and the installation accuracy of the food processor are improved.

In order to realize the arrangement of the clutch mechanism 4 and the clutch driving mechanism 9 in the horizontal direction, as shown in fig. 2 and fig. 8, the food processor further comprises a second transmission mechanism 10, the clutch mechanism 4 is in transmission connection with the clutch driving mechanism 9 through the second transmission mechanism 10, and the clutch mechanism 4 and the clutch driving mechanism 9 are arranged side by side, so that the purpose of reasonable arrangement of the clutch mechanism 4, the power mechanism 3 and the clutch driving mechanism 9 in the shell 1 is achieved, and the clutch mechanism 4, the power mechanism 3 and the clutch driving mechanism 9 can reasonably utilize the limited space in the shell 1.

In order to clearly understand the structure of the second transmission mechanism 10, as shown in fig. 10 and 11, the second transmission mechanism 10 includes a sleeve 101 and a lever 102, the sleeve 101 is disposed on the mounting plate 2, the clutch assembly 42 is disposed in the sleeve 101 and connected to the sleeve 101 through a first sliding pair, the lever 102 is rotatably connected to the mounting plate 2, one end of the lever 102 is connected to the clutch assembly 42 through a second sliding pair, and the other end of the lever 102 is connected to the output end of the clutch driving mechanism 9 through a third sliding pair. When the output end of the clutch driving mechanism 9 moves, the output end of the clutch driving mechanism 9 drives the lever 102 to rotate relative to the mounting plate 2, and the other end of the lever 102 drives the clutch assembly 42 to move up and down along the vertical direction, so that the clutch assembly 42 is switched between the first position and the second position, and the switching of the rotating speed of the output mechanism 6 is realized. In order to effectively reduce the height of the food processor, the stroke S of the clutch assembly 42 in the vertical direction is 8mm to 15mm, and the preferred embodiment is 12.5mm with a moderate stroke S.

The motion precision of the simple structure and transmission of above-mentioned second drive mechanism 10 is higher, can realize the accurate control of clutch pack 42 place, and when the cooking machine was in different user state, the transmission of guaranteeing clutch pack 42 can be accurate and low rotational speed output 412 to be connected or high rotational speed output 4112 is connected.

Specifically, as shown in fig. 10 and 11, the first sliding pair includes a first slider 421 provided on the clutch assembly 42 and a first sliding groove 1011 formed in the sleeve 101 and extending in the vertical direction, and the first slider 421 can slide along the first sliding groove 1011. The second sliding pair includes a first sliding block 421 and a second sliding slot 1022 opened on the lever 102, and the first sliding block 421 can slide along the second sliding slot 1022. The third sliding pair includes a second slider 91 disposed at the output end of the clutch driving mechanism 9 and a third sliding slot 1021 disposed on the lever 102, and the second slider 91 can slide along the third sliding slot 1021. As shown in fig. 10, when the output end of the clutch drive mechanism 9 is in the initial state, the clutch pack 42 is in the high position. As shown in fig. 11, when the output end of the clutch drive mechanism 9 is in the extended state, the clutch pack 42 is in the low position.

As shown in fig. 10, the lever 102 is pivotally connected to the mounting plate 2 via a fulcrum O, a projected distance in the horizontal direction of a connecting line between the lever 102 and the clutch driving mechanism 9 and the fulcrum O is L1, a projected distance in the horizontal direction of a connecting line between the lever 102 and the clutch assembly 42 and the fulcrum O is L2, and L1 is greater than L2. Clutch drive mechanism 9 only needs to exert less drive power, just can realize lever 102 to the great motive force of clutch assembly 42, and the rotational speed switching process that realizes the cooking machine is more smooth and easy, can effectively save the energy consumption of cooking machine. Preferably, 1 < L1/L2 < 4.4, which can ensure smooth switching of the rotational speed of the food processor and moderate volume of the machine body 100, in this embodiment, L1/L2 is preferably 1.72.

As shown in fig. 10 and 11, the shape of the inner cavity of the sleeve 101 is the same as the outer contour shape of the clutch assembly 42, and the clutch assembly 42 can slide relative to the sleeve 101 in the vertical direction, so that a better guiding effect on the clutch assembly 42 can be achieved, the clutch assembly 42 is prevented from being deflected, and the rotating speed switching of the food processor is smoother.

Because the first transmission mechanism 7 is a pulley assembly, when the food processor is switched between the gear positions, the output end of the second transmission mechanism 10 and the lever 102 move, the annular transmission belt 73 in the pulley assembly is easily wound on the output end of the second transmission mechanism 10 or the lever 102, and the pulley assembly cannot normally operate, so that the food processor cannot normally operate. In order to solve the above problem, the first transmission mechanism 7 and the second transmission mechanism 10 are disposed on the upper and lower sides of the mounting plate 2, the mounting plate 2 can separate the annular transmission belt 73 from the second transmission mechanism 10, and can also separate the lever 102 from the annular transmission belt 73, so that the annular transmission belt 73 can be prevented from being wound on the output end of the second transmission mechanism 10 or the lever 102.

In addition, the rotating speed of the annular transmission belt 73 of the belt pulley assembly in the working process is very high, and there are many parts on the power mechanism 3, and if the parts on the power mechanism 3 fall off the first transmission mechanism 7, the transmission precision of the belt pulley assembly will be affected, and in order to solve the above problems, as shown in fig. 8, the first transmission mechanism 7 and the power mechanism 3 are located on two sides of the mounting plate 2, so that the dynamic and static separation of the internal structure of the food processor is realized, and the respective normal operation of each part is realized.

In order to clearly understand the structure of the clutch driving mechanism 9, as shown in fig. 13, the clutch driving mechanism 9 includes a body and an output rod 96, the output rod 96 can move telescopically relative to the body in the up-and-down direction, and the output rod 96 is connected with the second transmission mechanism 10. The shifting of the different gears of the clutch mechanism 4 can be driven by the telescopic movement of the output rod 96. Wherein, clutch drive mechanism 9 includes shell 92, motor 93 and lead screw 94, sets up motor 93 and lead screw 94 in the shell 92, and the cover is equipped with output rod 96 between shell 92 and the lead screw 94, and motor 93 can drive lead screw 94 and rotate so that output rod 96 is relative shell 92 and is telescopic motion along the upper and lower direction, and in order to effectively save the space of cooking machine, output rod 96 is 25mm ~ 50mm, preferred 32.4mm along the stroke of vertical direction. In addition, in order to avoid the clutch driving mechanism 9 to be too large in size along the up-down direction, the clutch driving mechanism 9 further comprises a gear set 95, the motor 93 is in transmission connection with the lead screw 94 through the gear set 95, so that the motor 93 and the lead screw 94 are arranged side by side, and the space occupied by the clutch driving mechanism 9 in the vertical direction can be effectively reduced. Specifically, the gear set 95 includes a first gear 951 and a second gear 952 that are engaged with each other, the first gear 951 being disposed coaxially with the lead screw 94, and the second gear 952 being disposed coaxially with the output shaft of the motor 93.

Since the power mechanism 3 generates vibration during operation, the vibration is transmitted to the mounting plate 2. If the bottom mounting with the body is on mounting panel 2, then will lead to the top of output rod 96 to be great along the distance of vertical direction apart from mounting panel 2, deflect certain contained angle (gamma angle) when the body is relative its mounted position, the top of output rod 96 can be along the great distance of horizontal direction skew than its mounted position, lead to the transmission precision variation of output rod 96 and lever 102, can't realize the accurate control of separation and reunion actuating mechanism 9 to clutch assembly 42, can't realize the accurate switching of cooking machine rotational speed. In order to solve the above problem, as shown in fig. 10, the body is fixed on the mounting plate 2, and the fixed position of the body and the mounting plate 2 is close to the output rod 96, so the distance from the top end of the output rod 96 to the mounting plate along the vertical direction is greatly reduced, even if the output rod 96 is deviated by an angle γ relative to the mounting position, the deviation of the top end of the output rod 96 along the horizontal direction is also greatly reduced, thereby ensuring that the better transmission precision of the output rod 96 and the lever 102 is deteriorated, realizing the precise control of the clutch driving mechanism 9 on the clutch assembly 42, and realizing the precise switching of the rotating speed of the food processor. In addition, when output rod 96 was in the biggest state of stretching out, the scheme at mounting panel 2 was installed to the bottom that the height of the top of output rod 96 of this embodiment is less than the body far away, so the body can effectively reduce casing 1 along vertical direction size with mounting panel 2's fixed position near output rod 96, effectively reduces cooking machine along vertical direction size. In order to further utilize the space in the housing 1 reasonably, when the output rod 96 is in the extending state, the top end of the output rod 96 is not higher than the top end of the power mechanism 3, so that the size of the housing 1 in the vertical direction only needs to consider the power mechanism 3 with larger volume and the clutch mechanism 4.
