Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0024] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0025] Please refer to Figure 1-5 An embodiment of the present application provides an atomization device 1 , which includes a housing 11 , a heating element 12 and a sleeve 13 .

[0026] The housing 11 is formed with an opening 110 and a heating chamber 111, the heating chamber 111 is connected to the opening 110, and the heating chamber 111 is used to accommodate the aerosol matrix to be atomized; a first air inlet channel 112 is formed at the opening 110; a base assembly 14 is provided at the end of the heating chamber 111 away from the opening 110, and a second air inlet channel 141 connected to the heating chamber 111 is provided on the base assembly 14. The housing 11 serves as the overall external structure of the atomizing device 1, and one or more accommodating chambers can be formed inside it according to specific needs, and the accommodating chambers can be used to accommodate the components required for the atomizing device 1, including but not limited to the heating element 12, the pneumatic switch, the power supply assembly, the circuit board, etc., which are not limited in the embodiments of the present application.

[0027] Among them, please refer to Figure 2 In order to accommodate and heat the aerosol matrix, the housing 11 in the embodiment of the present application is formed with a heating chamber 111, which is connected to the opening 110 on the housing 11, so that the aerosol matrix can enter the heating chamber 111 through the opening 110. Generally speaking, the size of the heating chamber 111 is adapted to the size of the aerosol matrix to be atomized.

[0028] In order to avoid the situation where the heating chamber 111 fails to heat the aerosol matrix at the top of the heating chamber 111 during the heating of the aerosol matrix, thereby causing the aerosol generated by the heating of the aerosol matrix at the bottom to be absorbed by the aerosol matrix at the top and become difficult to inhale, the length of the heating chamber 111 is generally set to be greater than or equal to the length of the aerosol matrix. In this way, the heating of the aerosol matrix by the heating chamber 111 is all-round, and the situation where the aerosol matrix at the top is not left unheated will not occur, which is conducive to the aerosol inhalation operation.

[0029] The atomizing device 1 in the embodiment of the present application is compatible with both the aerobic heating mode and the anaerobic heating mode for the aerosol matrix. Among them, the aerobic heating mode refers to the need to mix air in the process of heating the aerosol matrix without burning, so the inside of the heating chamber 111 needs to be directly connected to the outside world in the aerobic heating mode; and the anaerobic heating refers to the aerosol matrix being in an oxygen-free or low-oxygen environment during the heating without burning process, so in this state, the inside of the heating chamber 111 is not directly connected to the outside world, and the generated aerosol is discharged through the Bernoulli principle when air is taken in through the opening 110. Therefore, in order to achieve the above purpose, a first air inlet channel 112 is provided at the opening 110 in the embodiment of the present application, and the first air inlet channel 112 is used to discharge the aerosol based on the Bernoulli principle in the anaerobic heating mode. Moreover, a base assembly 14 is provided at the end of the heating chamber 111 away from the opening 110. The base assembly 14 is used to carry the aerosol matrix. At the same time, a second air inlet channel 141 is opened on the base assembly 14. The second air inlet channel 141 is connected to the heating chamber 111. When the second air inlet channel 141 is connected to the outside, aerobic heating can be achieved.

[0030] The first air inlet channel 112 refers to the opening 110 of the atomizing device 1 which is not completely closed, and air can flow through the opening 110 in order to discharge the aerosol based on the Bernoulli principle; please refer to Figure 3 The anaerobic heating mode is mostly coordinated with the suction nozzle 4, the aerosol matrix 3, the cooling element and the suction nozzle 4 are connected in sequence, and an air outlet 42 and an air inlet 41 are provided on the suction nozzle, wherein the air inlet 41 is located at one end of the suction nozzle 4 close to the aerosol matrix 3, and the air outlet 42 is located at the end of the suction nozzle 4 away from the aerosol matrix 3; during the suction process of the suction nozzle 4, air enters the suction nozzle 4 from the air inlet 41, thereby forming a negative pressure in the suction nozzle 4, and the aerosol flows from the heating chamber 111 to the suction nozzle 4, and is discharged along the air outlet 42 of the suction nozzle 4.

[0031] In order to avoid clogging the air inlet on the mouthpiece and adapt to aerosol substrates of more sizes, in some optional embodiments, the atomizer 1 further includes an air inlet cavity 15, which is connected between the heating cavity 111 and the opening 110, and the inner diameter of the air inlet cavity 15 is larger than the inner diameter of the heating cavity 111. Since the inner diameter of the air inlet cavity 15 is larger than the inner diameter of the heating cavity 111, the air inlet cavity 15 can avoid covering the side of the aerosol substrate, and even if the length of the aerosol substrate is short, the air inlet on the mouthpiece can also be used to intake air through the gap formed between the air inlet cavity 15 and the mouthpiece, thereby improving the size adaptation range of the aerosol substrate.

[0032] In order to heat the aerosol matrix, the atomizing device 1 includes a heating element 12, which is arranged outside the heating chamber 111 or inserted inside the heating chamber 111, and is used to heat the aerosol matrix. The heating element 12 may include invasive heating or non-invasive heating according to its form, wherein invasive heating means that the heating element 12 needs to penetrate into the aerosol matrix to achieve heating, generally in a resistive heating mode, in which case the heating element 12 is inserted inside the heating chamber 111; non-invasive heating means that the heating element 12 is arranged outside the aerosol matrix for heating, and the heating method includes but is not limited to circumferential heating, bottom heating, etc., and the specific heating means may be resistive heating, infrared heating, electromagnetic heating, etc.

[0033] When the atomizing device 1 is used in the anaerobic heating mode, the second air inlet channel 141 needs to be closed, and when the atomizing device 1 is used in the aerobic heating mode, the second air inlet channel 141 needs to be connected to the outside. In order to realize that the second air inlet channel 141 can be switched between connecting to the outside and being closed, please refer to Figure 4 The atomizing device 1 includes a sleeve 13, which is at least partially sleeved outside the base assembly 14, and is provided with an air inlet 131 connecting the inside of the sleeve 13 with the outer space of the shell 11; the sleeve 13 and the base assembly 14 can slide relative to each other, so that the air inlet 131 connects the second air inlet channel 141 with the outer space of the shell 11, or separates the second air inlet channel 141 from the outer space of the shell 11. By sleeve-fitting the sleeve 13 outside the base assembly 14, the air inlet 131 on the sleeve 13 is used to realize the connection and disconnection with the second air inlet channel 141 on the base assembly 14; for details, please refer to Figure 5 When the air inlet 131 is connected to the second air inlet channel 141, since the air inlet 131 is connected to the outside, it is equivalent to connecting the second air inlet channel 141 to the outside, thereby achieving the conditions required for the aerobic heating mode; when the air inlet 131 is not connected to the second air inlet channel 141, only one end of the second air inlet channel 141 is connected to the heating chamber 111, and the other end is closed by the sleeve 13, so the second air inlet channel 141 is in a cut-off state from the outside, thereby meeting the conditions required for the anaerobic heating mode. The position switching between the sleeve 13 and the base assembly 14 is achieved based on the relative sliding between the sleeve 13 and the base assembly 14.

[0034] In some optional embodiments, in order to facilitate the sliding connection between the sleeve 13 and the base assembly 14, the sleeve 13 can be fixedly connected to the housing 11, and at least part of the base assembly 14 is slidably connected inside the sleeve 13. In this structure, since the sleeve 13 is fixedly connected to the housing 11, the sleeve 13 is relatively fixed, and the base assembly 14 is slidably connected to the sleeve 13. The base assembly 14 can be slid to achieve relative sliding between the base assembly 14 and the sleeve 13, so as to switch the connection between the air inlet hole 131 and the second air inlet channel 141.

[0035] In some optional embodiments, in order to adjust the positional relationship between the base assembly 14 and the sleeve 13 and improve the convenience of sliding switching of the base assembly 14, the base assembly 14 may specifically include a sliding rod 142 and a sliding control member 143; the sliding rod 142 includes a first end 1421 and a second end 1422 that are axially opposite to each other, and the first end 1421 is closer to the opening 110 than the second end 1422; the sliding control member 143 is connected to the second end 1422, and by controlling the sliding control member 143, the sliding rod 142 slides to the first position along its axial direction to connect the air inlet hole 131 with the second air inlet channel 141; or, by controlling the sliding control member 143, the sliding rod 142 slides to the second position along its axial direction to isolate the second air inlet channel 141 from the outside. A nested movable connection is formed between the slide rod 142 and the sleeve 13, wherein the sleeve 13 is sleeved on the outside of the slide rod 142, and the slide rod 142 can slide back and forth along the axial direction of the slide rod 142 in the internal space of the sleeve 13; the sliding control member 143 is connected to the slide rod 142, and the control operation of the sliding control member 143 is transmitted to the slide rod 142 to realize sliding in the corresponding direction, thereby realizing the switching of the connection between the second air inlet channel 141 and the air inlet hole 131.

[0036] Specifically, during the switching process, if the sliding rod 142 slides to the first position along its axial direction, the air inlet hole 131 is connected with the second air inlet channel 141, and the second air inlet channel 141 is connected with the outside through the air inlet hole 131, and the atomization device 1 enters the aerobic heating mode; if the sliding rod 142 slides to the second position along its axial direction, the air inlet hole 131 is staggered with the second air inlet channel 141, and the second air inlet channel 141 is closed by the sleeve 13, and the atomization device 1 enters the anaerobic heating mode.

[0037] The control means of the sliding control member 143 for the sliding rod 142 can be mechanical structure control or electric control. The sliding control member 143 is exposed to the housing, and the operator can directly control the sliding control member 143 from the outside, and then the control operation of the sliding control member 143 can be transmitted to the sliding rod 142 via the sliding control member 143, so that the sliding rod 142 slides accordingly.

[0038] In some optional embodiments, in order to facilitate the control of the slide bar 142 and reduce the complexity of the structure, the second end 1422 of the slide bar 142 may have a first assembly surface 1423, and the first assembly surface 1423 is inclined to the radial cross section of the slide bar 142; the slide control member 143 has a second assembly surface 1431 parallel to the first assembly surface 1423 near the second end 1422, and the second assembly surface 1431 is contact-connected with the first assembly surface 1423; by controlling the slide control member 143 to slide along the axis direction perpendicular to the slide bar 142, the first assembly surface 1423 and the second assembly surface 1431 are transmitted to the slide bar 142, so that the slide bar 142 slides along the axis direction. Since the slide bar 142 and the slide control member 143 are contact-connected through the parallel and inclined first assembly surface 1423 and the second assembly surface 1431, when the slide control member 143 slides in the horizontal direction, the inclined first assembly surface 1423 and the second assembly surface 1431 will convert the sliding direction into vertical sliding. Then, the movement of the sliding control member 143 in a direction perpendicular to the axis of the slide bar 142 will be converted into the sliding of the slide bar 142 in the direction of its axis. Under this structure, the sliding control member 143 can slide in parallel to the bottom wall of the shell, and the outer contour of the shell as a whole can be kept unchanged, and the structure will not expand or contract on the shell surface.

[0039] In some optional embodiments, in order to improve the air intake effect of the second air intake channel 141, a ventilation space 1424 is formed in the sliding rod 142; a first through hole 1425 is provided on the end surface of the sliding rod 142 located at the first end 1421, and the first through hole 1425 is connected to the ventilation space 1424; a second through hole 1426 is provided on the side wall of the sliding rod 142, and the second through hole 1426 is connected to the ventilation space 1424, and the first through hole 1425, the second through hole 1426 and the ventilation space 1424 form the second air intake channel 141. In order to ensure that the aerosol matrix is ​​fully heated in the aerobic heating mode, the optimal air inlet position of the second air inlet channel 141 is the bottom of the heating chamber 111. Therefore, a first through hole 1425 can be opened on the end face of the first end portion 1421 of the sliding rod 142, and the first through hole 1425 is located at the bottom of the heating chamber 111; a second through hole 1426 is opened on the side wall of the sliding rod 142, and the first through hole 1425 and the second through hole 1426 are connected through the ventilation space 1424 formed in the sliding rod 142, and the second through hole 1426 is slidably matched with the air inlet hole 131 on the sleeve 13. When the second through hole 1426 is connected with the air inlet hole 131, the second air inlet channel 141 is connected with the outside, thereby realizing aerobic heating; when the second through hole 1426 is staggered with the air inlet hole 131, the second air inlet channel 141 is closed, thereby realizing anaerobic heating.

[0040] In some optional embodiments, to facilitate processing, the sliding rod 142 may include an axially distributed first connecting member 144 and a second connecting member 145, wherein the first connecting member 144 is closer to the opening 110 than the second connecting member 145; a ventilation space 1424 is provided on the first connecting member 144, and a groove 146 is provided in the ventilation space 1424 near the second connecting member 145; the first connecting member 144 and the second connecting member 145 are fixedly connected through the groove 146 of the ventilation space 1424, and the groove 146 of the ventilation space 1424 is sealed. The sliding rod 142 can be split into two or more parts, wherein the first connecting member 144 can be used to form a first through hole 1425, a second through hole 1426 and a ventilation space 1424, and a groove 146 is set at the ventilation space 1424 near the second connecting member 145, and then the second connecting member 145 can be connected based on the groove 146, and the second connecting member 145 blocks the groove 146, so that the first connecting member 144 and the second connecting member 145 can be processed separately, and then the two can be connected and assembled.

[0041] The first connecting member 144 and the second connecting member 145 may be connected by interference fit, threaded fit, or by glue.

[0042] In some optional embodiments, in order to achieve the heating operation of the aerosol matrix, the heating element 12 may specifically include a heating tube, which is arranged around the outside of the heating chamber 111; the length of the heating chamber 111 is greater than or equal to the length of the aerosol matrix. By setting the length of the heating chamber 111 to be greater than or equal to the length of the aerosol matrix, it is possible to avoid the aerosol matrix at the top being located outside the heating chamber 111, resulting in the inability to heat, so that each part of the aerosol matrix can be heated, allowing the aerosol to be discharged smoothly.

[0043] In some optional embodiments, in order to ensure heating efficiency, the atomizing device 1 further includes a heat insulator 16, which is coated outside the heating tube. The heat insulator 16 can be provided to prevent the heat generated by the heating tube from escaping to the outside, thereby ensuring the heating stability of the aerosol matrix and preventing other components of the atomizing device 1 from being damaged by high temperature.

[0044] The atomizing device 1 provided in the embodiment of the present application can slide relative to each other between the sleeve 13 and the base assembly 14, so that the second air inlet channel 141 of the base can be connected and disconnected with the outside world respectively. When the second air inlet channel 141 is connected, aerobic heating is achieved. When the second air inlet channel 141 is disconnected, aerosol inhalation in the anaerobic heating state is achieved through the top first air inlet channel 112, which effectively improves the compatibility of the atomizing device and improves the user experience.

[0045] The present application also provides an atomization device, please continue to refer to Figure 1-5 The atomization device includes a power supply assembly (not shown) and the atomization device 1 in the embodiment of the present application; the power supply assembly is electrically connected to the atomization device 1 and is used to provide power to the heating element 12.

[0046] The power supply assembly is used to provide electrical energy to the heating element 12 in the atomizing device, and the heating element 12 is used to heat the aerosol matrix into an aerosol. The atomizing device can be a disposable product or a cartridge-changing product. For a disposable atomizing device, the heating element 12 is fixedly connected to the power supply assembly and the housing; for a cartridge-changing atomizing device, the heating element 12 is detachably connected to the power supply assembly, and the heating element 12 and the power supply assembly can be replaced according to the usage.

[0047] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
