[0033] Embodiment 1:

[0034] Please refer to Figures 1 to 8B , an embodiment of the present utility model provides a heat-not-burn device 100, including a main body 10, a mouthpiece 20, and a cartridge 30. The main body 10 has a mounting position 11 and a mounting channel 12, and the mounting channel 12 communicates with the mounting position 11. The mouthpiece 20 is detachably connected to the mounting channel 12 of the main body 10 and can move within the mounting channel 12. The cartridge 30 is movably connected or detachably connected to the mounting position 11. The cartridge 30 is provided with a receiving cavity 31 and a loading / unloading opening 32, and the loading / unloading opening 32 communicates with the receiving cavity 31. The receiving cavity 31 is used to receive the smoke-generating article 200. Wherein, the mouthpiece 20 has a socket portion 21, and the socket portion 21 can move from the mounting channel 12 to pass through the loading / unloading opening 32 and be socketed with the end of the smoke-generating article 200 in the receiving cavity 31, so that when the mouthpiece 20 is detached from the main body 10, it can drive the smoke-generating article 200 to move out of the receiving cavity 31 through the loading / unloading opening 32 and the mounting channel 12.

[0035] During specific implementation, when the smoke-generating article 200 in the receiving cavity 31 is heated to completion, the socket portion 21 of the mouthpiece 20 can be moved to pass through the loading / unloading opening 32 and be socketed with the smoke-generating article 200. When the mouthpiece 20 is detached from the mounting channel 12 of the main body 10, since the socket portion 21 of the mouthpiece 20 is socketed with the smoke-generating article 200, it can drive the socketed smoke-generating article 200 to move out of the receiving cavity 31 through the loading / unloading opening 32 and the mounting channel 12 in sequence, thereby realizing the removal of the used smoke-generating article 200. After the used smoke-generating article 200 is removed, the empty mouthpiece 20 can be reinstalled into the mounting channel 12 and continue to be used.

[0036] By adopting the above technical solution, the accommodating chamber 31 is provided to accommodate the smoking product 200, and the length of the smoking product 200 is greatly shortened compared to the aerosol product with a filter, so the height of the accommodating chamber 31 does not need to be set very high, which is conducive to cleaning the accommodating chamber 31. In addition, by setting the magazine 30 to be movably connected or detachably connected to the mounting position 11, the magazine 30 can be at least partially separated from the mounting position 11, so that the magazine 30 is at least partially exposed to the host 10, which is conducive to cleaning the magazine 30 separately. By setting the use of the gas nozzle 20 to take out the old smoking product 200, it is possible to avoid scalding the user when taking out the smoking product 200, and only the smoking product 200 is replaced, and the gas nozzle 20 can continue to be used, avoiding waste and reducing costs. Therefore, the heating without burning device 100 provided in this embodiment is easy to clean, improves the user's experience, and also avoids waste and reduces costs.

[0037] It should be noted that the gas nozzle 20 has a suction position and a removal position. When the gas nozzle 20 is in the suction position, the smoking article 200 can be heated to generate aerosol, and the aerosol can flow to the gas nozzle 20 and be sucked out. When the gas nozzle 20 is in the removal position, the smoking article 200 cannot be heated. Specifically, when the gas nozzle 20 is in the suction position, the gas nozzle 20 is installed in the installation channel 12, but does not sleeve the smoking article 200. The aerosol generated by heating the smoking article 200 in the accommodating cavity 31 can flow to the gas nozzle 20 and be sucked out through the gas nozzle 20; when the gas nozzle 20 is in the removal position, the gas nozzle 20 is sleeved on the smoking article 200, and can drive the smoking article 200 to move out of the accommodating cavity 31 and detach from the main unit 10 when the gas nozzle 20 is detached from the main unit 10. In addition, the length of the nozzle 20 exposed outside the main unit 10 when it is in the removal position is shorter than the length of the nozzle 20 exposed outside the main unit 10 when it is in the suction position. The user can determine whether suction can be performed based on the exposed length of the nozzle 20.

[0038] The accommodating chamber 31 has a closed state and an open state, and the magazine 30 can move relative to the mounting position 11 to switch the accommodating chamber 31 between the closed state and the open state. When the accommodating chamber 31 is in the closed state, the magazine 30 is installed in the mounting position 11, and the access opening 32 is connected to and communicates with the mounting channel 12, so that the sleeve portion 21 can move from the mounting channel 12 to pass through the access opening 32, and the aerosol in the accommodating chamber 31 can flow to the air nozzle 20 through the access opening 32; when the accommodating chamber 31 is in the open state, the magazine 30 is at least partially separated from the mounting position 11, and the access opening 32 is exposed to the host 10.

[0039] That is, when the accommodating chamber 31 is in a closed state, the magazine 30 is placed in the installation position 11, the access opening 32 of the magazine 30 is docked and communicated with the installation channel 12, the accommodating chamber 31 is communicated with the gas nozzle 20, and the aerosol generated by the smoking article 200 in the accommodating chamber 31 can flow to the gas nozzle 20 through the access opening 32, so that the aerosol flows out of the gas nozzle 20, and the sleeve portion 21 of the gas nozzle 20 can move to pass through the access opening 32 and be sleeved with the smoking article 200 in the accommodating chamber 31. When the accommodating chamber 31 is in an open state, the magazine 30 is at least partially separated from the installation position 11, and the access opening 32 is exposed to the host 10. At this time, the empty accommodating chamber 31 can be cleaned through the exposed access opening 32, and a new smoking article 200 can be loaded into the accommodating chamber 31.

[0040] See also Figure 6 , the air nozzle 20 further includes an exposed portion 22, and the sleeve portion 21 is arranged at one end of the exposed portion 22 close to the accommodating cavity 31. That is, when the air nozzle 20 is installed in the installation channel 12, the sleeve portion 21 is arranged close to the accommodating cavity 31, and the exposed portion 22 is arranged away from the accommodating cavity 31 and exposed outside the main unit 10. In this way, the user can use the exposed portion 22 as a force point to apply force to the air nozzle 20, so that the air nozzle 20 can move in a direction close to the accommodating cavity 31 and then be sleeved with the smoking article 200, and the air nozzle 20 can move in a direction away from the accommodating cavity 31 and then be removed from the main unit 10. In addition, the user can also place part of the exposed portion 22 in the mouth and inhale the aerosol flowing into the air nozzle 20 through the exposed portion 22.

[0041] See also Figure 6 and Figure 8A , Figure 8B The sleeve portion 21 has a sleeve cavity 211, which is used to be sleeved with the smoking product 200. In specific implementation, the inner wall of the sleeve cavity 211 is interference-fitted with the outer periphery of the smoking product 200, so that the air nozzle 20 can drive the smoking product 200 to move out of the accommodating cavity 31 when being removed from the main unit 10. Figure 8B The figure shows that the inner wall of the free end of the sleeve portion 21 is trumpet-shaped, that is, the free end of the sleeve cavity 211 is trumpet-shaped with a small inside and a large outside. In this way, when the sleeve portion 21 moves from top to bottom toward the accommodating cavity 31, when the sleeve portion 21 passes through the access opening 32 of the accommodating cavity 31, the trumpet-shaped end of the sleeve cavity 211 first contacts the outer periphery of the smoking article 200, so that the smoking article 200 can be guided into the sleeve cavity 211 of the gas nozzle 20 by using the inclined surface of the sleeve cavity 211.

[0042] See also Figure 6 and Figure 8A , Figure 8BThe inner wall of the sleeve cavity 211 is provided with a positioning step 212 protruding along the radial direction of the sleeve cavity 211. The positioning step 212 is used to interfere with the smoking article 200 to limit the embedding depth of the smoking article 200 in the sleeve cavity 211. By providing the positioning step 212 to interfere with the smoking article 200, the smoking article 200 can be prevented from being excessively sleeved in the sleeve cavity 211, thereby facilitating the removal of the smoking article 200 from the sleeve cavity 211.

[0043] In one embodiment, the distance from the positioning step 212 to the opening of the sleeve cavity 211 is less than the length of the accommodating cavity 31 along its axial direction, and is greater than or equal to half of the length of the accommodating cavity 31 along its axial direction. In order to allow the smoking article 200 to be well accommodated in the accommodating cavity 31, the length of the accommodating cavity 31 is usually set to be the same as the length of the smoking article 200 or slightly longer than the length of the smoking article 200. By setting the distance from the positioning step 212 to the opening of the sleeve cavity 211 to be less than the length of the accommodating cavity 31 along its axial direction, and greater than or equal to half of the length of the accommodating cavity 31 along its axial direction, the distance from the positioning step 212 to the opening of the sleeve cavity 211 is less than the length of the smoking article 200, and greater than or equal to half of the length of the smoking article 200. In this way, the smoking article 200 will not be too insufficiently inserted into the sleeve cavity 211, and can also be prevented from being excessively inserted into the sleeve cavity 211. On the one hand, it can ensure that the smoking article 200 is firmly inserted into the sleeve cavity 211, and on the other hand, the smoking article 200 can be easily taken out of the sleeve cavity 211.

[0044] See also Figure 1 and Figure 4 The heat-not-burn device 100 further includes a filter 40, which is disposed in the gas nozzle 20, and is used to filter the aerosol entering the gas nozzle 20. In this way, the user's experience can be improved.

[0045] In one embodiment, the air nozzle 20 has a first connection portion 23, and the outer wall of the mounting channel 12 and / or the host 10 has a second connection portion 13, and the first connection portion 23 is detachably connected to the second connection portion 13 to achieve a detachable connection between the air nozzle 20 and the host 10.

[0046] See also Figure 4, in one embodiment, the first connecting portion 23 includes a mating portion 231, and the second connecting portion 13 includes a clamping portion 131. The clamping portion 131 is located within the installation channel 12 and is used for interference fit with the mating portion 231. In this embodiment, the entire outer surface of the nozzle 20 is set as the mating portion 231, and the entire inner wall of the installation channel 12 is set as the clamping portion 131. When the nozzle 20 is installed within the installation channel 12, its outer periphery is in interference fit with the inner wall of the installation channel 12. It can be understood that in other embodiments, it is also possible to set a part of the inner wall of the installation channel 12 as the clamping portion 131.

[0047] Please refer to Figure 9 , in another embodiment, the first connecting portion 23 includes a mating portion 231, and the second connecting portion 13 includes a seal 132. The seal 132 is located within the installation channel 12 and is used for interference fit with the mating portion 231. Among them, the entire outer surface of the nozzle 20 is set as the mating portion 231. When the nozzle 20 is installed within the installation channel 12, its outer periphery is in interference fit with the seal 132 located within the installation channel 12.

[0048] During specific implementation, the first connecting portion 23 and the second connecting portion 13 can also be set to other structures to achieve detachable connection between the nozzle 20 and the host 10. For example, the first connecting portion 23 includes an external thread, and the second connecting portion 13 includes an internal thread. The internal thread is provided on the inner side of the installation channel 12 for threaded connection with the external thread; or, the first connecting portion 23 includes a first magnetic attraction member, and the second connecting portion 13 includes a second magnetic attraction member. The second magnetic attraction member is provided on the inner side of the installation channel 12 for magnetic attraction cooperation with the first magnetic attraction member; or, the first connecting portion 23 includes a first buckle, and the second connecting portion 13 includes a second buckle. The second buckle is provided on the inner side of the installation channel 12 and / or the outer wall of the host 10 for cooperation with the first buckle.

[0049] Please refer to Figure 2 , Figure 3 and Figure 7 , the installation position 11 includes a notch 111 formed on the side portion of the host 10, penetrating at least two side surfaces of the host 10. When the accommodation cavity 31 is in an open state, the access opening 32 of the magazine 30 is located outside the notch 111. In this embodiment, the host 10 includes a first side wall 112, a second side wall 113, and a third side wall 114. The first side wall 112 and the second side wall 113 are oppositely arranged, and the third side wall 114 is connected between the first side wall 112 and the second side wall 113. The first side wall 112, the second side wall 113, and the third side wall 114 enclose the notch 111 of the installation position 11. This installation position 11 penetrates three side surfaces of the host 10, and one end of the installation channel 12 close to the installation position 11 is opened on the first side wall 112.

[0050] In specific implementation, a connection component (not shown in the figure) can be provided between at least one of the first side wall 112, the second side wall 113, and the third side wall 114 and the cartridge 30, so that the cartridge 30 is movably connected to the installation position 11 or detachably connected to the installation position 11. For example, a slider is provided on one of the cartridge 30 and the installation position 11, and a chute slidably engaged with the slider is provided on the other. The detachable connection is achieved through the sliding cooperation between the slider and the chute. In addition, the cartridge 30 and the installation position 11 can also be movably connected by providing an eccentric rotating shaft and a rotating groove.

[0051] Please refer to Figure 7 , the cartridge 30 further has a first air inlet 33, and the first air inlet 33 is used to communicate the outside of the cartridge 30 and the accommodation cavity 31. By providing the first air inlet 33, the gas outside the cartridge 30 can enter the accommodation cavity 31, so that the aerosol in the accommodation cavity 31 can flow out along with the air flow.

[0052] Please refer to Figure 2 , Figure 4 and Figure 7 , the first air inlet 33 is disposed opposite to the access port 32. The main body 10 further includes a second air inlet 14 and an air intake passage 15 communicating with the second air inlet 14. When the accommodation cavity 31 is in a closed state, the end of the air intake passage 15 away from the second air inlet 14 is docked and communicated with the first air inlet 33. When using the heat-not-burn device 100, the access port 32 is usually located above the accommodation cavity 31, so that the smoking article 200 is placed in the accommodation cavity 31 and is not easily separated from the accommodation cavity 31, and the aerosol generated by the smoking article 200 can flow upward and out of the accommodation cavity 31. The first air inlet 33 is disposed opposite to the access port 32, then the first air inlet 33 is located below the cartridge 30, and the end of the air intake passage 15 away from the second air inlet 14 is opened on the second side wall 113 so that it can be docked and communicated with the first air inlet 33 when the accommodation cavity 31 is in a closed state. Among them, the second air inlet 14 can be opened at any part of the main body 10, such as the bottom or side of the main body 10.

[0053] In specific implementation, the gas can enter the accommodation cavity 31 from the outside through the second air inlet 14, the air intake passage 15, and the first air inlet 33, and flow through the accommodation cavity 31 to the nozzle 20. The aerosol in the accommodation cavity 31 can flow to the nozzle 20 along with the air flow.

[0054] It can be understood that in other embodiments, the first air inlet 33 can also be opened on the side wall of the magazine 30, that is, the first air inlet 33 is located at the side of the accommodating chamber 31. In specific implementation, the gas can enter the accommodating chamber 31 from the side of the heat-not-burn device 100 through the notch 111 and the first air inlet 33, and then flow to the gas nozzle 20 through the access port 32, and the aerosol in the accommodating chamber 31 can be sucked out to the gas nozzle 20 together with the gas.

[0055] In one embodiment, the diameter of the first air inlet 33 is smaller than the diameter of the access opening 32. In a specific application, the diameter of the first air inlet 33 is smaller than the diameter of the smoking article 200, so that the smoking article 200 can be ensured not to be separated from the accommodating chamber 31 through the first air inlet 33.

[0056] In one embodiment, the heat-not-burn device 100 further includes a sealing ring 50 disposed on at least one of the mounting position 11 and the magazine 30. The sealing ring 50 is used to be disposed around the outer periphery of the access opening 32 when the magazine 30 is mounted on the mounting position 11, and seal the gap between the magazine 30 and the mounting position 11. In a specific implementation, the aerosol generated by heating the smoking article 200 located in the accommodating cavity 31 flows to the gas nozzle 20 through the access opening 32. By providing the sealing ring 50 to seal the gap between the magazine 30 and the mounting position 11, it is possible to prevent the aerosol from flowing out of the gap between the magazine 30 and the mounting position 11 when flowing to the gas nozzle 20 through the access opening 32, thereby improving the air tightness of the heat-not-burn device 100.

[0057] See also Figure 2 , Figure 4 and Figure 7 In one embodiment, the sealing ring 50 is disposed on the side of the magazine 30 facing the first side wall 112 and is disposed around the access opening 32. In a specific implementation, a sealing groove 34 is disposed on the side of the magazine 30 facing the first side wall 112, and the sealing ring 50 is installed in the sealing groove 34. It can be understood that in other embodiments, the sealing ring 50 can also be disposed on the first side wall 112. When this technical solution is adopted, the sealing groove 34 can be disposed on the first side wall 112.

[0058] In one embodiment, the heat-not-burn device 100 further includes a heating component (not shown in the figure), which is used to heat the smoking article 200 in the accommodation chamber 31 to generate aerosol.

[0060] Embodiment Two:

[0061] The main difference between the heat-not-burn device 100 and the aerosol generating system provided in this embodiment and those in Embodiment One lies in the different numbers of accommodation chambers 31 arranged in the cartridge 30, specifically: in Embodiment One, the cartridge 30 is provided with one accommodation chamber 31; while in this embodiment, the cartridge 30 is provided with at least two accommodation chambers 31.

[0062] Please refer to Figure 10 and Figure 11 , the cartridge 30 is provided with at least two accommodation chambers 31 and at least two access ports 32. The access ports 32 are in one-to-one correspondence with the accommodation chambers 31. When the cartridge 30 is installed at the installation position 11, each accommodation chamber 31 can be selectively communicated with the installation channel 12 through the access port 32 communicating therewith, that is, only the smoking article 200 in one accommodation chamber 31 is heated to generate aerosol and flows to the mouthpiece 20.

[0063] By providing at least two accommodation chambers 31, at least two smoking articles 200 can be loaded into or taken out of the cartridge 30 at one time, without the need to load a new smoking article 200 after using up one smoking article 200 to continue using. In this way, the frequency of replacing the smoking article 200 is reduced, the time difference between two replacements of the smoking article 200 is extended, and the user experience is greatly improved.

[0064] Among them, the accommodating cavities 31 can be provided with two, three, four, five, etc. The arrangement of multiple accommodating cavities 31 is not limited. They can be arranged in a straight line, in a curve, or in a circular arrangement. Preferably, multiple accommodating cavities 31 are arranged in a circular pattern along the central axis of the cartridge 30.

[0065] In a specific implementation, the cartridge 30 is at least partially detached from the mounting position 11 so that all the accommodating cavities 31 of the cartridge 30 are in an open state. A new smoking article 200 is placed in each accommodating cavity 31, and then the cartridge 30 is installed in the mounting position 11. When the smoking article 200 in the accommodating cavity 31 connected to the installation channel 12 is heated up, the mouthpiece 20 can be moved in the direction close to this accommodating cavity 31. After the mouthpiece 20 is sleeved on the smoking article 200, the mouthpiece 20 is then moved in the direction away from this accommodating cavity 31 and detached from the main body 10, so that the heated smoking article 200 can be taken out. After the smoking article 200 is separated from the mouthpiece 20, the mouthpiece 20 is reinstalled in the installation channel 12, and the next accommodating cavity 31 of the cartridge 30 is connected to the installation channel 12 to heat the smoking article 200 in the next accommodating cavity 31 until the smoking articles 200 in all the accommodating cavities 31 of the cartridge 30 are heated up and taken out by the mouthpiece 20. Then the cartridge 30 is at least partially detached from the mounting position 11, and new smoking articles 200 are loaded into the cartridge 30 again.

[0066] Please refer to Figure 10 and Figure 11 , the cartridge 30 is further provided with at least two first air inlets 33, and the first air inlets 33 are in one-to-one correspondence with and communicate with the accommodating cavities 31. When the cartridge 30 is installed in the mounting position 11, the first air inlets 33 corresponding to the accommodating cavities 31 connected to the installation channel 12 are butted and communicate with the air inlet channel 15.

[0067] Except for the above differences, the heat-not-burn device 100 and other components provided in this embodiment can be designed with reference to Embodiment 1, and details are not described herein again.

[0068] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention.
