Example one

As shown in fig. 1, a bean sprout fresh-keeping device comprises an atomizing device 1 and a water vapor guiding device 3, wherein the atomizing device 1 is connected with the water vapor guiding device 3 through a connecting pipe 2, the water vapor guiding device 3 comprises a plurality of branch pipes 30, exhaust holes 31 are formed in the branch pipes 30, the atomizing device 1 is used for atomizing liquid water into water vapor, then the water vapor is conveyed to the water vapor guiding device 3 through the connecting pipe 2, and the water vapor is discharged from the branch pipes 30 and the exhaust holes 31.

The atomizing device 1 can adopt the existing mature ultrasonic atomizing technology, the simplest method is only to refit a household humidifier, and a power supply can be directly introduced into a power supply on a refrigerated transport vehicle, so that the atomizing device is convenient and reliable, and the change is small, and the cost is lower. The water vapor generated by the atomization device 1 is injected into the connecting pipe 2 and the water vapor guiding device 3 by a blower or an air pump of the atomization device 1 and is finally discharged. The water vapor guiding device 3 is formed by welding a plurality of pipes which are directly communicated with each other. Place in the plastic bag that is equipped with the bean sprouts when steam guiding device 3 uses, the best is in the middle of the bean sprouts, is provided with the area that sprays that many lateral pipes 30 can enlarge steam on steam guiding device 3, guarantees that the bean sprouts can both have sufficient moisture to keep moist.

Example two

Through long-term transportation practice, the bean sprouts are placed in the refrigerator car for transportation, but because the vegetables and fruits that the refrigerator car needs to transport and customers are more often need to open the carriage door for unloading, the temperature in the refrigerator car changes greatly, and the adoption of only atomizing humidification is not ideal. Therefore, on the basis of the first embodiment, the device is optimized: as shown in fig. 2, the atomizing device 1 includes a cooling unit 10 and an atomizing unit 11, the cooling unit 10 is provided with a container for containing the liquid water, a cooling device is provided in the container for cooling the liquid water, and the atomizing unit 11 is used for atomizing the cooled liquid water. In this embodiment, it is preferable that the cooling device is an electronic cooling plate, and the atomizing unit 11 is disposed in the container. Through cooling down atomizing again to liquid water, not only can realize the moisturizing of bean sprouts like this, also cooled down the central point of bean sprouts in the plastic bag simultaneously, kill two birds with one stone, also improved the quality of bean sprouts like this greatly.

EXAMPLE III

In practice, it is found that when the bean sprouts are transported for a long time, because the atomizing and humidifying time is long, atomized water vapor is changed into liquid water to cause water accumulation in the plastic bag, so that the soaked bean sprouts are easy to send, rot and deteriorate. In order to solve this problem, as shown in fig. 3, a drainage device is added to the first embodiment or the second embodiment. The drainage device comprises a drainage water pump 4, a drainage connecting pipe 5 and a water suction pipe 6, wherein the top end of the water suction pipe 6 is connected with one end of the drainage connecting pipe 5, and the other end of the drainage connecting pipe 5 is connected with the drainage water pump 4. When in use, the water suction pipe 6 is placed in the plastic bag and the end of the water suction pipe, which is not connected with the drainage connecting pipe 5, is positioned at the bottom of the plastic bag as much as possible so as to suck water. As soon as liquid water is produced in the plastic bag, the water discharge pump 4 is started to discharge the water through the water discharge connecting pipe 5 and the water suction pipe 6. This ensures very good water retention in the plastic bag and minimizes the possibility of decay and deterioration of the bean sprouts.

In fig. 3, the vapor guide device 3 and the water suction pipe 6 are integrally configured for convenience of operation, but this is not the only way, and the vapor guide device 3 and the water suction pipe 6 can be independently placed as long as the problems of humidification and water suction can be solved.

As shown in fig. 4, the vapor guide device 3 includes an annular communication pipe 32, a plurality of branch pipes 30 are fixedly connected to the outer periphery of the annular communication pipe 32, respectively, and the other ends of the branch pipes 30 extend downward. A water vapor inlet pipe 33 is fixedly arranged on the annular communicating pipe 32, and the water vapor inlet pipe 33 is connected with the connecting pipe 2. A fixing rod 34 is fixedly arranged on the inner side of the annular communicating pipe 32 along the radial direction, and one end of the fixing rod 34 far away from the annular communicating pipe 32 is fixedly connected with the suction pipe 6. The suction pipe 6 and the branch pipe 30 are arranged in parallel with each other. The structure is made to be convenient for one-time operation when being inserted into the bean sprouts, and the working efficiency is improved. The annular communicating pipe 32 is bent into a circular ring shape from a pipe, and the inner cavity of the annular communicating pipe 32 is communicated with the inner cavity of the branch pipe 30 and the steam inlet pipe 33. After entering the water vapor, the water vapor inlet pipe 33 distributes the water vapor to each branch pipe 30 through the annular communicating pipe 32 for spraying. The fixing rod 34 is used for fixing the suction pipe 6 in the middle of the annular communicating pipe 32, the annular communicating pipe 32 is not communicated with the suction pipe 6, and the top of the suction pipe 6 protrudes out of the annular communicating pipe 32, so that the connection with the drainage connecting pipe 5 is more convenient.

As shown in fig. 4, it is found in practical use that if the bottom of the branch pipe 30 is a circular structure, the bean sprouts are easily scratched when the plastic bag containing the bean sprouts is inserted, and the bean sprouts are also not easily inserted due to the resistance of the bean sprouts, therefore, the bottom of the branch pipe 30 is provided in a cone structure, such a structure is convenient to be inserted into the bean sprouts to avoid the damage of the bean sprouts.

Example four

In use, the mode of the third embodiment is convenient, but the draining water pump 4 is opened for a long time or even idles, is easy to damage and consumes electric energy, and in addition, the draining water pump cannot be accurately and automatically controlled according to the humidity and the temperature in the plastic bag, so that the device is optimized in the third embodiment. As shown in figure 5, the device is added with a control unit, and a sensor 7 is fixedly arranged on the peripheral side wall of the suction pipe 6, and the sensor 7 is used for detecting humidity, temperature and liquid level. The control unit is respectively and electrically connected with the atomization device 1, the drainage water pump 4 and the sensor 7. The control unit should be provided with a control circuit board, and a microcontroller such as a single chip microcomputer is arranged on the control circuit board and used for being electrically connected with the sensor 7, acquiring the humidity, the temperature and the liquid level in the plastic bag from the sensor 7, and further correspondingly controlling the atomizing device 1 and the drainage water pump 4. For example, when the humidity is detected to be lower than a preset value, the atomization amount of the atomization device 1 is started or increased; when the temperature in the plastic bag is detected to be higher than a preset value, the refrigerating capacity of the refrigerating unit is started or increased; when the accumulated water in the plastic bag is detected to reach a preset value, the drainage water pump 4 is controlled to drain water and the like. Therefore, the automatic and accurate operation can be realized without manual participation, the energy consumption is reduced, and the cost is saved.

In practice, when the drainage pump drains water, plastic bag films near the suction pipe 6 are easily sucked into the suction pipe 6, so that the suction pipe 6 is blocked and cannot normally absorb water, and finally drainage is affected, so that bean sprouts are soaked in water and are easily deteriorated; in addition, because the bean sprouts have a lot of impurities such as bean skins, and the bean sprouts are easily sucked into the water suction pipe 6, the water suction groove 60 and the mesh cover 61 are designed. As shown in fig. 6, a water suction groove 60 is formed in the periphery of the bottom end of the water suction pipe 6, and a mesh cover 61 is fixedly sleeved at the bottom end of the water suction pipe 6. The net cover 61 is used for filtering impurities to prevent blockage, and the water suction groove 60 is a lateral channel which is added into the water suction pipe 6 to ensure normal water inlet. By adopting the structure, the water suction pipe 6 can be effectively prevented from being blocked by a plastic bag or impurities, and the stability of the device is further improved.

EXAMPLE five

In the third and fourth embodiments, the bottom end of the suction pipe 6 is of a plane structure, and the problems that the bean sprouts are scratched by the edge of the bottom end of the suction pipe 6 and the insertion resistance is too large due to too large area and the bean sprouts are inserted into the plastic bags containing the bean sprouts. In this regard, optimization was performed on the basis of the third embodiment.

As shown in fig. 7, a water suction groove 60 is formed in the periphery of the bottom end of the water suction pipe 6, and a scratch-proof protection device 62 is slidably disposed in the inner cavity of the bottom end of the water suction pipe 6.

As shown in fig. 8, an arc-shaped slot 63 is formed in the inner wall of the water suction pipe 6 near the bottom end, and the center of the arc-shaped slot 63 coincides with the center of the water suction pipe 6.

As shown in fig. 9, the scratch protection device 62 includes a housing 620, the housing 620 is composed of an upper housing 6200 having a cylindrical tubular structure and a lower housing 6201 having a hollow conical structure, and one end of the upper housing 6200 is fixedly connected to a large end of the lower housing 6201. The outer wall of the lower casing 6201 is provided with a plurality of meshes 62011 for water inflow and blocking impurities, and the center of the small end of the lower casing 6201 is provided with a mandril hole 62010.

Go up in the casing 6200 and cross centre of a circle interval fixed being provided with first fixed strip 621 and second fixed strip 622, two fixed strips pass the center of last casing 6200 and respectively with the last casing 6200 inner wall fixed connection of both sides promptly, be provided with certain clearance between first fixed strip 621 and the second fixed strip 622 and be used for placing buckle piece 624 and pressure spring 625. The middle parts of the first fixing strip 621 and the second fixing strip 622 are both provided with fixing strip ejector rod holes 6210.

The periphery of the upper shell 6200 is provided with three buckling grooves 62000 in a penetrating manner, and the three buckling grooves 62000 are positioned between the two fixing strips. The three fastening grooves 62000 are arranged on the same plane and are mutually spaced by 120 degrees.

Ejector pins 623 are slidably arranged in the ejector pin holes 62010 and the ejector pin holes 6210 of the fixing strips in a penetrating mode, the bottom ends of the ejector pins 623 protrude out of the lower shell 6201, and the bottom ends of the ejector pins 623 are arranged into a conical structure, so that resistance caused by overlarge area and possibility of scratching bean sprouts can be avoided.

A clamping block 624 is fixedly arranged on the top rod 623, the clamping block 624 is positioned between the first fixing strip 621 and the second fixing strip 622, a pressure spring 625 is sleeved on the top rod 623, and the pressure spring 625 is positioned between the clamping block 624 and the first fixing strip 621.

As shown in fig. 10, the locking block 624 includes a locking central disc 6240, the locking central disc 6240 is a circular disc structure, a disc hole 6241 is opened at the center of the locking central disc 6240, and the push rod 623 penetrates and is fixed in the disc hole 6241. The periphery of the buckle center disc 6240 is fixedly provided with three clamping pieces 6242, the three clamping pieces 6242 are in a strip-shaped structure, and the three clamping pieces 6242 are respectively distributed at intervals of 120 degrees. An elastic groove 6243 is arranged on the bottom surface of the joint of the buckling central disc 6240 and the clamping piece 6242. The resilient slot 6243 is an arc-shaped slot, the length direction of which is parallel to the width direction of the card 6242. The function of the resilient groove 6243 is: when the buckling block 624 is driven upwards by the push rod 623, the outer end of the clamping piece 6242 is also clamped in the arc-shaped clamping groove 63, and the clamping piece 6242 is easier to bend downwards due to the elastic groove 6243, so that the outer end is quickly retracted, and unlocking is realized.

The three clamping pieces 6242 are respectively slidably inserted into the three fastening grooves 62000 and protrude out of the upper housing 6200. The card 6242 is made of an elastic material.

Under normal conditions, the shell 620 protrudes out of the bottom of the suction pipe 6, and the whole lower shell 6201 is located outside the suction pipe 6, at this time, the buckling block 624 extends outwards under the pressure of the pressure spring 625 and reaches the straight state of the three clamping pieces 6242, and after the three clamping pieces 6242 are completely straight, the buckling block extends out of the three buckling grooves 62000 and is inserted into the arc-shaped clamping groove 63, so that the anti-scraping protection device 62 is locked, and the anti-scraping protection device cannot freely slide in the suction pipe 6. When the water suction pipe 6 is held and inserted into the bean sprouts, the bottom of the plastic bag can be easily checked because the bottom of the shell 620 is of a hollow cone structure and the resistance is very small. The plastic bag is placed in the storage box for transportation, the water suction pipe 6 is continuously pressed downwards to enable the bottom of the ejector rod 623 on the scratch-proof protection device 62 to be abutted against the plastic bag and the bottom plate of the storage box, at this time, the ejector rod 623 drives the buckle central disc 6240 on the buckle block 624 and one end of each of the three clamping pieces 6242 to move upwards, meanwhile, the part, protruding out of the upper shell 6200, of each of the three clamping pieces 6242 is inwards retracted, after the clamping pieces are retracted to a certain distance, the three clamping pieces 6242 are separated from the arc-shaped clamping grooves 63, the scratch-proof protection device 62 is unlocked, and the whole scratch-proof protection device 62 moves towards the upper surface of the water suction pipe 6 under the action of pressure and retracts into the water suction pipe 6. Because the lower housing 6201 is provided with a plurality of meshes 62011 and a lateral water suction groove 60, the water suction pipe 6 can well filter impurities and prevent blockage. After the scraping prevention protection device 62 is additionally arranged, the bean sprouts can be better prevented from being scratched, and the resistance when the bean sprouts are inserted is greatly reduced. The whole structure is very ingenious and easy to manufacture, and the cost is low.
