In the present embodiment, the heating element 1 of the smoking set with adjustable heating stroke of the present invention is substantially the same as the existing products in the market, and the heating principle and implementation manner thereof can be understood by referring to many prior arts represented by the patent document with the application number CN212185126U, and will not be described herein again.

In this embodiment, the heating element 1 comprises a base 13 provided with a heating body 11, the base 13 being provided with a coupling slot 131, the bowl 2 being provided with a flange 221 inserted in the coupling slot 131 to rotatably couple the bowl 2 to the heating element 1. Specifically, the cup 2 and the base 13 are coaxially arranged, the connecting groove 131 is annular and is arranged on the side wall of the base 13, and the flange 221 is arranged at the end of the cup 2 and can be clamped into the connecting groove 131 to form clearance fit with the connecting groove 131, so that the cup 2 and the heating element 1 can rotate relatively.

In the present embodiment, the cup 2 is provided with an insertion opening 222 into which the cartridge is inserted, and the inner wall of the insertion opening 222 extends toward the inside of the cup 2 to form the heating cavity 21. Specifically, the inside cavity of bowl 2, the inner wall of inserted hole 222 is to bowl 2 inside extension, with the inside separation of bowl 2 for the heating chamber 21 and the regulation chamber 22 of mutual intercommunication, heating chamber 21 can play the guide effect to the cartridge, avoids the cartridge to insert bowl 2 in-process and takes place the skew or buckle, and heating member 11 and cartridge contact subalternation problem.

In this embodiment, as shown in fig. 1-3, one end of the heating body 11 is fixedly connected to the base 13, and the other end extends into the cigarette cup 2, and includes a fixing section disposed in the adjusting cavity 22 and a heating section inserted into the heating cavity 21, and the sliding block 12 is sleeved on the heating section and can slide up and down in the heating cavity 21. Specifically, the middle of the slider 12 is provided with a connecting hole, and the slider 12 forms clearance fit with the heating body 11 through the connecting hole, so that the slider 12 can move along the axial direction of the heating body 11 under stress. When the tobacco heating device is used, a cigarette cartridge is inserted into the heating cavity 21 from the insertion opening 222 until the cigarette cartridge is abutted against the sliding block 12, part of the heating section of the heating body 11 is inserted into the cigarette cartridge to heat tobacco, the insertion length of the heating section is the length of the heating stroke S, and the heating stroke S can be adjusted by changing the position of the sliding block 12 on the heating section.

In this embodiment, as shown in fig. 4, the guiding element 4 is a coil spring, and is sleeved on the fixed section of the heating body 11, one end of the guiding element is fixedly connected with the sliding block 12, the other end of the guiding element is fixedly connected with the base 13, and a spiral channel 41 is formed between two adjacent coils 51 of the coil spring 5; the transmission piece 3 is a slender round rod, two ends of the transmission piece are respectively connected with the inner wall of the cigarette cup 2, and the transmission piece is inserted between two adjacent spiral coils 51 of the spiral spring 5 and respectively abutted against the two adjacent spiral coils 51; when the cigarette cup 2 rotates, the transmission part 3 rotates around the heating body 11 along with the cigarette cup 2, so that the abutting position between the transmission part 3 and the helicoid 51 changes, the helicoid 51 is driven to move towards the direction close to the slide block 12 or away from the slide block 12, and the position of the slide block 12 on the heating section of the heating body 11 is changed. Specifically, as shown in fig. 5, the inner wall of the smoking cup 2 is not shown, and only the movement process between the transmission member 3 and the coil spring 5 is shown.

In this embodiment, as shown in fig. 5-a, in the initial state, there are three coils 51 on each side of the transmission member 3, when the transmission member 3 rotates to the position shown in fig. 5-c, the coil 51 below the transmission member 3 and adjacent to the transmission member 3 is pushed to the upper side of the transmission member 3, at this time, the number of the coils 51 above the transmission member 3 is increased from three to four, and the length of the part of the coil spring 5 above the transmission member 3 is increased, so that the slider 12 is pushed to slide upwards; the number of the coils 51 below the transmission member 3 is reduced from three to two, and the two coils 51 below the transmission member 3 are stretched to ensure that the axial length is unchanged. Wherein, the adjusting range of the heating stroke S of the smoking set with the adjustable heating stroke is the maximum stretching length of the spiral spring 5, when the spiral spring 5 is stretched to the maximum, only one coil 51 is left below the transmission part 3, and the deformation amount of the coil 51 reaches the maximum, so that the smoking set cannot be continuously stretched

In this embodiment, the driving member 3 not only cooperates with the coil spring 5 to convert the rotation motion into the linear motion, but also plays a role in stopping, and after the rotation stops, the driving member 3 abuts against the coil 51 of the coil spring 5 to prevent the coil 51 from extending and retracting in the axial direction, so as to ensure that the sliding block 12 does not slide in the axial direction after the adjustment. In addition, as shown in fig. 3, the heating cavity 21 includes an abutting end 211 extending into the cigarette cup 2, the distance H between the transmission member 3 and the abutting end 211 is smaller than the thickness W of the sliding block 12, when the sliding block 12 moves to the abutting end 211, the sliding block 12 and the transmission member 3 abut against each other, and the sliding block 12 is prevented from sliding into the adjusting cavity 22.

In this embodiment, because coil spring 5's flexible characteristic for coil spring 5's axial length is variable, has reduced the length of the regulation chamber 22 of bowl 2 greatly, makes the length of adjusting chamber 22 only need set up to coil spring 5 length under the compression state can, has reduced the bulk size of smoking set, makes the more small and exquisite nimble that the smoking set can design.

In this embodiment, in order to prevent the slider 12 from coming off from the end of the heating body 11, the length of the coil spring 5 in the maximum stretching state is smaller than that of the heating body 11, so that the farthest distance of the movement of the slider 12 toward the heating cavity 21 is always smaller than that of the heating body 11, and the slider 12 is ensured not to slip out from the end of the heating body 11.

In this embodiment, as shown in fig. 4, the axis of the transmission member 3 is perpendicular to the axis of the heating body 11, so as to ensure that two ends of the transmission member 3 are respectively abutted against two adjacent coils 51, thereby better adjusting the coil spring 5.

Example 2: this embodiment is substantially the same as embodiment 1, except that: the guide member 4 is a sleeve 6 which is movably connected with the heating body 11 and can reciprocate along the axial direction of the heating body 11, a spiral groove 61 is arranged on the outer wall of the sleeve 6, and the groove 61 forms a spiral channel 41. Specifically, the sleeve 6 is cylindrical, a connecting hole is formed in the sleeve along the axis direction, and the sleeve 6 is sleeved on the heating body 11 through the connecting hole and is in clearance fit with the heating body 11, so that the sleeve 6 can reciprocate along the axis direction of the heating body 11.

In this embodiment, the axis of the transmission member 3 is inclined at the same angle as the thread angle of the spiral channel 41, so that the transmission member 3 can be inserted into the spiral groove 61, and when the transmission member 3 rotates with the smoking cup 2, the sleeve 6 can be driven to spirally rise. The specific motion principle can refer to a ball screw component, and is not described in detail herein.

In the present embodiment, since the sleeve 6 is movably connected to the transmission member 3 and the heating body 11, in order to prevent the sleeve 6 from slipping beyond the transmission member 3 during the moving process, a stop block 62 is disposed at one end of the sleeve 6 away from the slider 12, and when the sleeve 6 moves to the maximum stroke toward the adjustment chamber 22, the stop block 62 abuts against the transmission member 3.
