In the second relative state, the cover 20 exposes the charging interface 16 for charging the battery 121.

Specifically, when the cover 20 is completely fitted over the main body 10 (which may be referred to as a first relative state), the cover 20 covers the charging interface 16 to protect the charging interface 16. When the cover 20 slides relative to the main body 10 such that the main body 10 and the cover 20 are maintained in the second relative state, the cover 20 exposes the charging interface 16 to charge the smoking set 100 through the charging interface 16.

The charging interface 16 may be one or more of a COM interface, a USB interface, a Mini-USB interface, or a Micro-USB interface, and the number of the charging interfaces 16 may be one or more, and the invention does not specifically limit the type and number of the charging interfaces 16.

in this embodiment, as shown in fig. 4, the main body 10 is provided with a charging interface 16, and the charging interface 16 is a USB interface, so as to improve the versatility of the charging interface 16 of the smoking set 100.

In the present embodiment, as shown in fig. 3 and 4, the pins of the charging interface 16 are soldered on the circuit board 13 and electrically connected to the pads on the circuit board 13. The circuit board 13 is used for electrically connecting the charging interface 16 with the battery 121, so as to charge the battery 121 through the charging interface 16. The plug end of the charging interface 16 is exposed through an opening in the side wall. The charging interface 16 is provided on the side wall of the mounting case 11, and when charging is required, it is not necessary to completely remove the cover 20 from the main body 10, thereby preventing the cover 20 from being lost during charging.

Alternatively, the charging interface 16 is disposed on the side wall of the main body 10 and can be close to both ends of the main body 10 (especially, the end far from the battery 121) to shorten the size of the cover 20, so that the smoking set 100 is smaller and more flexible to adjust.

In one embodiment, the position limiting structure 40 includes a first protrusion 21 disposed on an inner sidewall of the housing 22 and a second protrusion 111 and a third protrusion 112 disposed on an outer sidewall of the body 10. Wherein the second protrusion 111 and the third protrusion 112 are disposed at an interval to form a limiting groove 113 between the second protrusion 111 and the third protrusion 112.

With continued reference to fig. 3 and 4, in the present embodiment, the second protrusion 111 and the third protrusion 112 may be disposed on the mounting shell 11 and the protection cover 30 at the same time. Specifically, the protective cover 30 may be fixed on one side of the mounting case 11, and the second and third protrusions 111 and 112 and the stopper groove 113 are provided on the side of the main body 10 and the protective cover 30 away from each other.

Wherein, the first protrusion 21 may be disposed around an inner sidewall of the case 22 in a circumferential direction of the case 22. Likewise, the second protrusion 111 and the third protrusion 112 may also be disposed around the outer sidewall of the body 10 along the circumferential direction of the body 10 to enhance the fixing effect, so that the connection is more stable.

In the present embodiment, as shown in fig. 2 and 4, the second protrusions 111 and the third protrusions 112 are only provided on two opposite sidewalls of the main body 10 to optimize the internal layout of the smoking article 100.

The cross sections of the first protrusion 21, the second protrusion 111, and the third protrusion 112 in the sliding direction parallel to the cover 20 may be trapezoidal, triangular, or arc-shaped, so as to reduce the resistance of the first protrusion 21 in the process of moving to the limiting groove 113, thereby facilitating sliding.

specifically, as shown in fig. 4, in the present embodiment, the first projection 21, the second projection 111, and the third projection 112 have a trapezoidal shape in cross section in parallel to the sliding direction of the cover body 20.

When the cover 20 is slid in a direction away from the main body 10, the trapezoidal surface of the first protrusion 21 contacts the trapezoidal surface of the second protrusion 111, and when the trapezoidal surface with a certain inclination angle receives an external force, the first protrusion 21 is pushed to move in a direction away from the second protrusion 111, so that the resistance of the first protrusion 21 when passing over the second protrusion 111 is reduced, so that the first protrusion 21 enters the limiting groove 113, and the cover 20 and the main body 10 are maintained in a second relative state, as shown in fig. 8. At this time, the lid 20 is fixed to the main body 10, and the charging port 16 of the main body 10 is completely exposed, so that the battery 121 can be charged. It will be readily appreciated that the stop arrangement 40 could be reversed, i.e.: the second and third protrusions 111 and 112 are provided on the inner sidewall of the cover body 20, and the first protrusion 21 is provided on the outer sidewall of the main body 10.

In another embodiment, the position limiting structure 40 includes a positioning hole and a positioning protrusion respectively disposed on the inner side wall of the housing 22 and the outer side wall of the body 10. For example, a positioning protrusion may be provided on the inner side wall of the cover body 20, and a positioning hole may be provided on the outer side wall of the main body 10, so that when the cover body 20 is slid in a direction away from the main body 10, the positioning protrusion on the cover body 20 enters the positioning hole when the positioning protrusion moves to the positioning hole, thereby maintaining the cover body 20 and the main body 10 in the second relative state. Similarly, the positioning hole can be disposed on the inner side wall of the cover 20, and the positioning protrusion can be disposed on the outer side wall of the main body 10. The positioning protrusion can also apply elastic force by the elastic body, so that the positioning protrusion is pushed into the positioning hole by the elastic body when the positioning protrusion is aligned with the positioning hole, and the positioning protrusion compresses the elastic body to move in the direction away from the positioning hole when the positioning protrusion is disengaged from the positioning hole. The portion of the positioning protrusion that mates with the positioning hole may be in the shape of a portion of a sphere. The positioning hole can be a through hole or a concave part.

In a first relative state, as shown in fig. 3 and 4, one end of the heating element 144 is positioned outside the chimney 23 and connected to the electrode 146; the other end is inserted through and extends out of the relief hole 235 to be located in the chimney 23. The portion located within the cartridge 23 is inserted inside the smoking article 50 so that the tobacco in the smoking article 50 is heated to produce an aerosol.

alternatively, as shown in FIG. 7, the heating element 144 has a gap between its outer side wall and the inner side wall defining the relief hole 235, such that air from outside the chimney 23 enters the chimney 23 through the gap to deliver the smoke generated by heating the tobacco product 50 for smoking by the user.

Wherein, in one embodiment, the heating element 144 may be cylindrical in shape and the side of the cylindrical heating element 144 adjacent to the smoking article 50 is tapered. The cylindrical heating element 144 may increase the contact area of the heating element 144 with the tobacco product 50, increasing the heating rate.

As shown in FIG. 2, in the present embodiment, the heating element 144 is flat to reduce frictional resistance as the heating element 144 is inserted into the smoking article 50.

Optionally, the heating element 144 is triangularly shaped at an end thereof adjacent the lid 20 to further reduce frictional resistance during insertion of the heating element 144 into the smoking article 50 to facilitate insertion of the smoking article 50.

Since most of the tobacco products 50 on the market are cylindrical, the chimney 23 is set to be cylindrical in the embodiment of the present invention to match the shape of the cylindrical tobacco product 50, as shown in fig. 11. The avoiding hole 235 is a strip-shaped hole, and the strip-shaped avoiding hole 235 is formed along the diameter direction of the bottom wall 239. By providing diametric relief holes 235, the heating elements 144 can be symmetrically distributed in the smoking article 50 to provide uniform heating of the smoking article 50.

In general, the sheet heating element 144 preferentially heats tobacco near both sides of the heating element 144 when heating the cylindrical tobacco product 50. The atomization of the tobacco product 50 in the region of smaller radial extent is thus more efficient, whereas the atomization of the tobacco product 50 in the region of greater radial extent from the heating body is more delayed. Air enters the chimney 23 through the relief holes 235 in the bottom wall 239 of the chimney 23 and carries away the generated smoke. When the smoking article 50 is heated to a certain extent, the tobacco adjacent the heating element 144 is fully heated, and at this point, air entering through the bottom relief holes 235 will carry away the smoke of the over-heated tobacco, thereby causing the smoke inhaled by the user to have a scorched flavor, which affects the taste.

In order to sufficiently heat and atomize the tobacco in the region farther from the sheet heating element 144, in the present embodiment, as shown in fig. 9, an air inlet hole 236 is further opened on the side wall of the smoke tube 23, and the air inlet hole 236 is used for introducing air so that the tobacco located between the air inlet hole 236 and the smoke opening 221 contacts with the air, thereby accelerating the atomization of the tobacco product 50 in the part of the smoke tube 23.

In the embodiment of the invention, the bottom wall 239 of the smoke tube 23 is provided with the avoiding hole 235, the side wall of the smoke tube 23 is provided with the air inlet hole 236, the air inlet hole 236 on the side wall of the smoke tube 23 is blocked due to the small distance between the tobacco product 50 and the side wall of the smoke tube 23 in the first half of the heating period of the tobacco product 50, and the outside air is introduced through the avoiding hole 235 on the bottom wall 239 of the smoke tube 23, so that the tobacco in the central area contacting with the heating element 144 is fully heated. The tobacco product 50 shrinks in volume due to the heat and atomization, and the distance between the tobacco product 50 and the side wall becomes larger. In the latter half of the heating cycle of the tobacco product 50, the outside air enters the chimney 23 through the air inlet 236 on the sidewall of the chimney 23, so that the tobacco near the sidewall of the chimney 23 is sufficiently heated, the tobacco at the center is prevented from being excessively heated to generate scorched flavor, and a better taste can be obtained.

Wherein, the air intake holes 236 are distributed on one side of the side wall of the smoke tube 40 close to the bottom wall 239, so that the distance between the air intake holes 236 and the smoke outlet 221 is the largest, and the contact area of the air and the tobacco products 50 is the largest, thereby enabling more tobacco products 50 to be sufficiently heated and atomized, and avoiding the waste caused by insufficient contact of the air with the tobacco products 50 positioned between the air intake holes 236 and the bottom wall 239.

Optionally, the distance between the portion of the air intake apertures 236 closest to the bottom wall 239 and the bottom wall 239 is no greater than 5 mm. That is, the minimum distance between the air intake holes 236 and the bottom wall 239 is not greater than 5 mm; for example, the minimum distance may be 0mm, 0.5mm, 1mm, 2mm, 4mm, 5mm, and the like.

In the present embodiment, as shown in fig. 10, the air inlet holes 236 are circular holes, and the minimum distance between the air inlet holes 236 and the bottom wall 239 of the chimney 23 is zero, i.e. the distance between the center of the air inlet holes 236 and the bottom wall 239 is equal to the radius of the air inlet holes 236, i.e. the air inlet holes 236 are tangent to the bottom wall 239, so that the distance between the air inlet holes 236 and the bottom wall 239 is minimized, and the waste of the tobacco product 50 is avoided.

Further, as shown in fig. 11, the axial direction of the gas intake holes 236 may be disposed substantially perpendicular to the length direction of the escape holes 235 so as to maximize the contact area of the gas entering through the gas intake holes 236 with the heating member 144. By forming the air inlet holes 236 approximately perpendicular to the length direction of the avoiding holes 235, the incoming air flow can be spread symmetrically to the periphery of the air inlet holes 236, as shown in the air flow direction in fig. 11, so that the tobacco in the smoke tube 23 is heated uniformly, and the atomization efficiency can be effectively improved.

In one embodiment, the air inlet holes 236 may also be symmetrically disposed on both sides of the heating element 144 to provide uniform heating of the tobacco on both sides of the heating element 144.

Optionally, a plurality of intake holes 236 may be provided to increase intake efficiency. In this embodiment, as shown in FIG. 11, the plurality of air intake holes 236 are located on the same cross-section of the chimney 23 to provide uniform heating of the smoking article 50.

Alternatively, since the amount of tobacco on both sides of the heating member 144 is large, the plurality of air intake holes 236 may be distributed on both sides in the longitudinal direction of the heating member 144 so that the tobacco products 50 on both sides in the longitudinal direction of the heating member 144 are atomized more sufficiently. Of course, in other embodiments, the number and the arrangement position of the air inlet holes 236 can be properly selected according to the shapes of the chimney 23 and the heating element 144, and the application is not limited in particular.

Further, as shown in fig. 9, an abutting portion 237 is further provided on the side wall of the barrel 23 in a protruding manner, and the distance between the abutting portion 237 and the bottom wall 239 is smaller than the distance between the air intake hole 236 and the bottom wall 239, that is, the abutting portion 237 is located between the air intake hole 236 and the bottom wall 239, or the abutting portion 237 and the bottom wall 239 are arranged along the same plane.

alternatively, as shown in fig. 7, the abutment portion 237 abuts on an inner side wall of the protection cover 30. When the air introduced from the air vent 234 flows to the abutment 237, the flow direction of the air is changed due to the abutment 237 contacting the inner side wall of the protection cover 30, so that the air is introduced from the air inlet hole 236 into the inside of the funnel 23. Through set up butt portion 237 between the lateral wall of chimney 23 and the inside wall of safety cover 30, can also prevent that one side that casing 22 was kept away from to chimney 23 from rocking in lid 20, avoid heating member 144 and the dislocation of dodging hole 235 on the chimney 23 diapire 239, cause the grafting failure.

Alternatively, as shown in fig. 9 and 11, an air guide groove 238 is further formed in the abutment portion 237 at a position corresponding to the air intake hole 236, the air guide groove 238 being provided at a position corresponding to the air intake hole 236. The air guide groove 238 provided below the air intake hole 236 can guide the air flowing to the abutting portion 237 into the air intake hole 236, facilitating air intake.

Wherein the abutment 237 may be evenly disposed on the outer sidewall of the chimney 23 to evenly stress the chimney 23. In the present embodiment, as shown in fig. 7 and 9, the abutting portion 237 abuts against the inner sidewall of the protection cover 30 around the circumference of the cartridge 23, and is located in the same plane as the bottom wall 239 of the cartridge 23.

The abutment portion 237 provided in the circumferential direction makes the outer circumferential wall of the bowl 23 uniformly stressed. Abutment 237 abuts against the inside wall of protective cover 30, allowing more air from air vent 234 to enter air intake hole 236. The abutment 237 is coplanar with the bottom wall 239 and the distance between the air inlet aperture 236 and the bottom wall 239 is reduced to maximize the volume of the tobacco product 50 in contact with the air and avoid waste.

alternatively, as shown in fig. 7, when the cover 20 is closed relative to the main body 10, the side of the protection cover 30 away from the heating element 14 abuts on the housing 22. Specifically, when the cover 20 is closed with respect to the main body 10, two ends of the protection cover 30 abut against the housing 22 and the mounting shell 11, respectively, so as to reduce air diffusion to form a sealed space inside the protection cover main body 31, the sealed space can reserve a certain amount of air between the vent 234 and the air inlet hole 236, and the reserved air can be preheated by heat on the chimney 23, so that the temperature of the air entering the air inlet hole 236 is higher than the outside atmospheric temperature, and thus the taste can be improved.

Further, as shown in fig. 6, the protection cover main body 31 further has a bottom plate 34, the bottom plate 34 is disposed on one side of the protection cover main body 31 close to the heating assembly 14, and an avoiding groove 342 is opened on the bottom plate 34. As shown in fig. 2 and 7, a heater holder 145 for holding a heater 144 is protrusively provided on the heating unit 14.

As shown in fig. 7, when the protection cover 30 covers the heating element 14 and is connected to the mounting shell 11, the heating element clamping portion 145 is accommodated in the avoiding groove 342, and the bottom plate 34 abuts against the heating body 142, so that the heating element 14 can be fixed on the mounting shell 11, and the heating element 14 is prevented from shaking during use. On the other hand, the number of the mounting and fixing elements of the heating assembly 14 can also be reduced, and the structural complexity of the smoking set 100 is reduced, so that the mounting and dismounting are more convenient. In yet another aspect, the heater clamp 145 may also seal the air passage in the protective cover 30 to prevent the smoke from condensing back into the mounting case 11 and damaging the components such as the circuit board 13 and the battery 121 inside the mounting case 11.

In this embodiment, the heater clamping portion 145 is made of a plastic material to improve the sealing performance between the heater clamping portion 145 and the avoiding groove 342.

Further, a limiting groove and a limiting column which can be matched with each other are respectively arranged on the surface of the heating main body 142 exposed out of the mounting shell 11 and on the bottom plate 34 of the protection cover 30, so as to realize accurate positioning of the protection cover 30 and the heating assembly 14.

Specifically, in the present embodiment, as shown in fig. 5, the limiting grooves 147 are formed on the surface of the heating body 142 exposed out of the mounting case 11, and the limiting grooves 147 include two, and the two limiting grooves 147 are symmetrically distributed on the heating body 142.

As shown in fig. 6, the stopper posts 344 are formed at positions of the bottom plate 34 corresponding to the stopper grooves 147, and the displacement of the protection cover 30 can be prevented by the cooperation of the stopper posts 344 and the stopper grooves 147, so that the shaking of the heating assembly 14 in the installation case 11 can be prevented.

Optionally, the area of the avoiding hole 235 is smaller than the cross-sectional area of the inner cavity of the chimney 23, i.e. the area of the avoiding hole 235 is smaller than the cross-sectional area of the tobacco product 50, so as to avoid that the tobacco product 50 passes through the avoiding hole 235 to be located inside the main body 10, thereby avoiding that the excessively high temperature tobacco product 50 damages the circuit board 13 and other elements inside the main body 10.

As shown in fig. 12, the main body 10 and the cover 20 further have a third relative state in which the cover 20 is in transition from the first relative state to the second relative state. That is, the third relative state represents a state between the second relative state and the relative fixation of the cover 20 and the main body 10 after the cover 20 is moved from the first relative state.

In the third relative position, since the relief hole 235 is smaller than the tobacco product 50, when the cover 20 starts to move from the first relative position, the bottom wall 239 of the smoking barrel 23 pushes the tobacco product 50, so that the tobacco product 50 is moved out with the cover 20, so that at least part of the heating element 144 is extracted from the tobacco product 50, thereby facilitating the extraction of the tobacco product 50 from the smoking barrel 23. Therefore, when the lid 20 and the main body 10 are in the third relative state, the tobacco product 50 can be easily taken out and replaced.

Further, a first magnet and a second magnet are respectively provided on the main body 10 and the cover body 20, and magnetic forces of the first magnet and the second magnet attract each other to hold the main body 10 and the cover body 20 in the first relative state.

Specifically, as shown in fig. 12, a first magnet 24 is provided on the inner end surface of the lid body 20, and a second magnet 17 is provided on the side of the mounting case 11 close to the lid body 20, the first magnet 24 being disposed opposite to the second magnet 17.

When the cover 20 and the main body 10 are in the third relative state, after the force for moving the cover 20 is removed (i.e., when there is no artificial force acting on the cover 20), the second magnet 17 attracts the first magnet 24, so that the cover 20 moves toward the main body 10, and the cover 20 returns to the initial position and is maintained in the first relative state, as shown in fig. 4, so that the cover 20 covers the charging interface 16, and prevents foreign substances and moisture from entering the charging interface 16. By providing the first and second magnets 24 and 17 that attract each other, it is possible to keep the cover 20 at the initial position (first relative state) of the main body 10 when charging is not required, to completely cover the charging interface 16, and to prevent the charging interface 16 from being exposed to contaminate foreign substances when charging is not required.

Further, as shown in fig. 13, the main body 10 and the cover 20 also have a fourth opposing state. Specifically, when the cover 20 and the main body 10 are in the second relative state, the cover 20 is continuously moved from the direction away from the main body 10, and at this time, the first protrusion 21 passes over the third protrusion 112, so that the connection of the cover 20 and the main body 10 is released, so that the cover 20 can be removed from the main body 10, that is, the main body 10 and the cover 20 are maintained in the fourth relative state.

In the fourth relative state, the cover 20 is completely detached from the main body 10, so that the heating unit 14 and the like inside the main body 10 can be cleaned, repaired, and replaced.

Optionally, as shown in fig. 1 and fig. 2, a display screen 18 for displaying the power of the battery 121 and/or the output power of the battery 121 is further disposed on the mounting shell 11 of the smoking set 100, and the display screen 18 is electrically connected to the battery 121 through the circuit board 13. By setting the display screen 18, the user can check the remaining capacity of the battery 121 at any time, and estimate the remaining operating time of the battery 121. And the output power of the battery 121 can be checked through the display screen 18, so that the user can conveniently adjust the output power of the battery 121.

As shown in fig. 2, the main body 10 may further include a key 19 and a protective case 11A. As shown in fig. 1 and 3, the button 19 protrudes from the surface of the mounting case 11 and is disposed on the main body 10, and is electrically connected to the circuit board 13 and the battery 121, for controlling the smoking set 100 to heat the tobacco product 50 or stopping heating the tobacco product 50. The protective shell 11A is sleeved outside the mounting shell 11, so that the aesthetic appearance of the smoking set 100 can be improved, and the smoking set 100 can be protected.

In another aspect, the present invention further provides a method for installing a smoking set, which is used for installing the smoking set 100 described in the above embodiments.

As shown in fig. 14, the mounting method includes:

S10: the heating assembly is mounted on the mounting housing in a first direction.

Specifically, the heating body of the heating assembly is installed in the prepared hole on the installation case, and the heating member 144 is exposed out of the installation case.

S20: a protective cover is mounted on the mounting housing in a first orientation such that the heating assembly is surrounded by the protective cover.

specifically, the guide plate is aligned with the guide groove, and the protective cover is moved from the side of the mounting shell far away from the heating assembly to the direction close to the heating assembly, so that the guide plate slides relative to the guide groove, and the first clamping portion on the guide plate is clamped in the first clamping groove, and the third clamping portion is clamped in the second clamping groove.

S30: the cover body is installed on the installation shell along the first direction, so that the shell body covers the side, connected with the protection cover, of the installation shell.

specifically, the cover body can be sleeved at the tail end of one side of the installation shell where the protection cover is arranged, and the magnetic forces of the first magnet and the second magnet which are respectively arranged on the shell and the installation shell are mutually attracted so as to install the cover body on the installation shell.

The smoking set in the embodiment has a simple installation method, and the cover body, the protective cover and the heating assembly can be conveniently detached, so that elements in the smoking set can be conveniently cleaned, maintained and replaced.

the above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
