[0040] An atomization device 1 is provided in the embodiments of the present application.

[0041] Referring to Figures 1 to 3 The atomization device 1 comprises a main machine 10, a liquid storage cartridge 12 for storing aerosol generating medium, and an atomization assembly 11.

[0042] It should be noted that the atomization device 1 of the embodiments of the present application can be any type of atomization device 1. The atomization device 1 can be used in the technical fields of medical, cosmetic, health care, electronic atomization, etc. For example, the atomization device 1 can be a scalp administration atomization device 1. The aerosol generating medium can be a liquid medium, such as oil with added aroma components, medicinal liquid, etc.

[0043] The main machine 10 is used to provide a stable mounting platform and protection for the liquid storage cartridge 12 and other internal elements of the atomization device 1, and to reduce the influence of external impact on the internal elements.

[0044] The liquid storage cartridge 12 is a liquid storage structure with a certain capacity. Exemplarily, the liquid storage cartridge 12 is generally in a columnar structure.

[0045] Specifically, the main machine 10 has a cartridge accommodating cavity 10a, and the liquid storage cartridge 12 is accommodated in the cartridge accommodating cavity 10a.

[0046] The cartridge accommodating cavity 10a is used to provide space for the liquid storage cartridge 12, to provide protection for the liquid storage cartridge 12, and to reduce the influence of external impact on the liquid storage cartridge 12.

[0047] The atomization assembly 11 is detachably arranged at a first end of the main machine 10 along a first direction, and is used to atomize the aerosol generating medium discharged from the liquid storage cartridge 12. The first direction is parallel to the axial direction of the atomization device 1.

[0048] It can be understood that in the embodiments, the first direction, the axial direction of the atomization device 1, and the top-bottom direction can be consistent.

[0049] Specifically, the atomization assembly 11 is detachably connected with the main machine 10, that is, when the atomization assembly 11 is connected with the main machine 10, the connection part is stable and not easy to be loosened or separated, and when it is needed to separate the atomization assembly 11 from the main machine 10, the connection between the atomization assembly 11 and the main machine 10 can be released to take out the atomization assembly 11.

[0050] The detachable connection can enable the atomization assembly 11 to be connected with and detached from the main machine 10 as a whole.

[0051] The specific manner of detachable connection is not limited, and for example, can be threaded connection, buckle connection, plug-in connection, etc., which is not limited herein.

[0052] The liquid storage cartridge 12 is detachably connected with the atomization assembly 11, so that when the atomization assembly 11 is separated from the main machine 10 as a whole, the atomization assembly 11 carries the liquid storage cartridge 12 out of the cartridge accommodating cavity 10a.

[0053] Specifically, when the atomization assembly 11 is separated from the main machine 10 as a whole, the atomization assembly 11 can carry the liquid storage cartridge 12 out of the cartridge accommodating cavity 10a due to the connection between the liquid storage cartridge 12 and the atomization assembly 11, and after being taken out, the connection between the liquid storage cartridge 12 and the atomization assembly 11 is released, so that the liquid storage cartridge 12 and the atomization assembly 11 are separated, thereby achieving liquid supplement or replacement of the liquid storage cartridge 12 and cleaning or replacement of the atomization assembly 11, respectively.

[0054] Of course, during assembly, the atomization assembly 11 can be first connected with the liquid storage cartridge 12, and then the atomization assembly 11 and the liquid storage cartridge 12 as a whole are connected with the main machine 10, thereby increasing the installation stability.

[0055] The atomization device 1 provided by the embodiment of the present application can separate the atomization assembly 11 and the liquid storage cartridge 12 from the main machine 10 as a whole unit due to the connection between the liquid storage cartridge 12 and the atomization assembly 11 when the atomization assembly 11 is separated from the main machine 10 as a whole, and can also reduce the probability of leakage of aerosol generating medium in the liquid storage cartridge 12 when the liquid storage cartridge 12 is taken out alone, thereby being convenient and safe to operate and increasing the taking-out stability. After the atomization assembly 11 and the liquid storage cartridge 12 are taken out, the atomization assembly 11 and the liquid storage cartridge 12 are separated, thereby achieving liquid supplement or replacement of the liquid storage cartridge 12 and cleaning or replacement of the atomization assembly 11, respectively, and the liquid storage cartridge 12 and the atomization assembly 11 are convenient and reliable to disassemble and assemble.

[0056] In some embodiments, please refer to Figure 5The atomization assembly 11 has a liquid outlet 11a, a liquid channel 11b, a first gas channel 11c, and a first gas outlet 11d. The liquid outlet 11a and the first gas outlet 11d are exposed to the outside of the atomization device 1. The liquid channel 11b is connected to the liquid outlet 11a and the liquid storage cartridge 12. The liquid outlet 11a is used to spray the aerosol generating medium. The first gas outlet 11d is used to spray the gas for atomizing the aerosol generating medium sprayed from the liquid outlet 11a.

[0057] It can be understood that the spraying here refers to that the aerosol generating medium is sprayed from the liquid outlet 11a with a certain pressure and flow rate, and the gas is sprayed from the first gas outlet 11d with a certain pressure and flow rate.

[0058] Specifically, the first gas outlet 11d is connected to the first gas channel 11c. The aerosol generating medium in the liquid storage cartridge 12 is sprayed from the liquid outlet 11a through the liquid channel 11b and is combined with the gas sprayed from the first gas outlet 11d through the first gas channel 11c. The gas splits the aerosol generating medium to form a liquid film, a liquid filament, a liquid strip, and liquid droplets to complete the atomization.

[0059] It should be noted that the liquid outlet 11a and the first gas outlet 11d are exposed to the outside of the atomization device 1, which means that the liquid outlet 11a and the first gas outlet 11d can be seen from the outside. Therefore, the aerosol generated after the aerosol generating medium is atomized can be exposed to the outside to be used.

[0060] In this embodiment, the gas atomizes the aerosol generating medium sprayed from the liquid outlet 11a, that is, the first gas channel 11c and the liquid channel 11b are two independent channels to reduce the probability of premature mixing of the gas and the aerosol generating medium, increase the atomization effect, and obtain a better atomization effect by adjusting the gas flow and the liquid flow. The gas disperses the aerosol generating medium to form fine particles, forms an aerosol, and diffuses to the outside environment for use by the user, and has a good atomization effect.

[0061] In some embodiments, referring to Figure 2 The host 10 has a second gas channel 10b inside. The host 10 has an air inlet 10c away from the atomization assembly 11. The air inlet 10c is used to access an external pressure source. The second gas channel 10b is used to guide the airflow to the first gas channel 11c.

[0062] Here, the end of the host 10 away from the atomization assembly 11 can be the second end of the host 10 in the first direction, that is, the second end of the host 10 in the first direction is provided with an air inlet 10c, and an external pressure source is in communication with the second gas channel 10b through the air inlet 10c. The external pressure source compresses the gas to provide gas with a certain pressure and speed, so that the gas flow flows from the second gas channel 10b to the first gas channel 11c at high speed, and then is sprayed out through the first gas outlet 11d, so that the aerosol generation is dispersed into finer particles, and the atomization effect is improved.

[0063] It can be understood that the external pressure source can be a gas pump (also known as a compressor or air compressor).

[0064] It can be understood that the speed and intensity of the gas flow can be controlled by adjusting the output pressure of the external pressure source, and then the atomization effect can be adjusted.

[0065] In some embodiments, referring to Figure 2 , the host 10 includes a driving mechanism 102, the liquid storage cartridge 12 includes a bottle body 121 and a sealing piston 122 arranged in the bottle body 121, the bottle body 121 has an opening 121a at an end away from the atomization assembly 11, and one end of the driving mechanism 102 extends into the bottle body 121 through the opening 121a and holds the sealing piston 122 in a direction close to the atomization assembly 11 to drive the aerosol generating medium in the liquid storage cartridge 12 to flow to the liquid outlet 11a.

[0066] Specifically, the bottle body 121 is used to store the aerosol generating medium, and the sealing piston 122 is arranged in the bottle body 121. On the one hand, the sealing piston 122 can move under the driving action of the driving mechanism 102 to push the aerosol generating medium to flow to the liquid outlet 11a. On the other hand, the sealing piston 122 can play a sealing role, so that the aerosol generating medium in the bottle body 121 does not overflow from the sealing piston 122 when driven by the driving mechanism 102, thereby increasing the reliability of liquid supply.

[0067] In this embodiment, the driving mechanism 102 cooperates with the sealing piston 122 to drive the aerosol generating medium in the liquid storage cartridge 12 to flow to the liquid outlet 11a, so as to realize continuous liquid supply. The sealing piston 122 can move at a stable speed, thereby increasing the stability of liquid supply. At the same time, the driving force of the driving mechanism 102 can be adjusted to adjust the liquid supply speed and liquid supply amount, so as to obtain a good atomization effect.

[0068] In some embodiments, the host 10 includes a control unit and a detection unit, and the atomization device 1 includes a detection piece arranged on the atomization assembly 11. The detection piece is used to trigger the detection unit to generate an in-place detection signal when the atomization assembly 11 is assembled in place. The detection unit is electrically connected to the control unit.

[0069] That is, after the host 10 and the atomization assembly 11 establish a connection relationship, the detection piece triggers the detection unit to generate a position detection signal, that is, the atomization assembly 11 is assembled in place, and the detection unit transmits the position detection signal to the control unit, and the control unit determines that the atomization assembly 11 is installed according to the position detection signal.

[0070] In this embodiment, the detection piece and the detection unit cooperate to detect whether the atomization assembly 11 is assembled and whether it is assembled in place. In this way, the probability of missing the cleaning of the atomization assembly 11 can be reduced, and it can be confirmed whether the atomization assembly 11 is assembled to the expected position, so that the atomization assembly 11 is better, more reliable and stable, and is not easy to fall out during work.

[0071] The specific structure of the detection piece and the detection unit is not limited. For example, the detection piece can be a magnet, and the detection unit can be a magnetic reed switch.

[0072] In some embodiments, the control unit is further configured to control the driving mechanism 102 to move to the initial position when the detection unit detects that the atomization assembly 11 is separated from the host 10.

[0073] It can be understood that the initial position here refers to the position of the driving mechanism 102 when it does not receive a movement signal, that is, when the liquid storage bullet 12 is in a full liquid state and is installed in the bullet body accommodating cavity, the driving mechanism 102 is in contact with the sealing piston 122 but does not exert a driving force.

[0074] In this embodiment, when the atomization assembly 11 is separated from the host 10, the atomization assembly 11 carries the liquid storage bullet 12 away from the host 10, and the driving mechanism 102 moves to the initial position. Therefore, when the liquid storage bullet 12 is refilled or replaced with a new liquid storage bullet 12 and then installed in the bullet body accommodating cavity, the corresponding position of the driving mechanism 102 does not change, and the driving mechanism 102 does not interfere with the installation of the liquid storage bullet 12, thereby increasing the installation reliability.

[0075] In some embodiments, please refer to Figures 5 to 7 The liquid storage bullet 12 includes an elastic sealing cover 123 arranged at one end of the bottle body 121, and the atomization assembly 11 includes a needle 111, the needle 111 penetrates through the elastic sealing cover 123, the needle 111 communicates the liquid passage 11b and the aerosol generating medium in the bottle body 121, and the liquid storage bullet 12 and the atomization assembly 11 are detachably connected by means of the friction force between the needle 111 and the elastic sealing cover 123.

[0076] Specifically, the elastic sealing cover 123 is used for sealing, under the action of the elastic sealing cover 123 and the sealing piston 122, the aerosol generating medium in the liquid storage bullet 12 is located in a closed space and will not overflow when the liquid storage bullet 12 is not docked with the needle 111. The elastic sealing cover 123 is a structure with certain elastic properties, the needle 111 has a sharp end, and the needle 111 can pass through the elastic sealing cover 123 through the sharp end to communicate the liquid channel 11b and the aerosol generating medium in the bottle body 121, so as to facilitate the liquid storage bullet 12 to deliver the aerosol generating medium to the liquid channel 11b.

[0077] Exemplarily, the elastic sealing plug can be made of elastic materials such as rubber or silicone.

[0078] It can be understood that when the needle 111 penetrates the elastic sealing cover 123, due to the resilience and friction coefficient of the elastic sealing cover 123 itself, a greater friction force can be generated when the needle 111 penetrates, and the part where the needle 111 is arranged in the elastic sealing cover 123 can be tightly wrapped by the elastic sealing cover 123 to generate a friction force. Thus, the detachable connection between the liquid storage bullet 12 and the atomization assembly 11 is realized through the friction force.

[0079] In this embodiment, through the cooperation of the needle 111 and the elastic sealing cover 123, the communication of the liquid channel 11b and the aerosol generating medium in the bottle body 121 is realized, and the detachable connection between the liquid storage bullet 12 and the atomization assembly 11 is also realized, so that the docking of the atomization assembly 11 and the liquid storage bullet 12 is more simple and convenient, and liquid leakage is avoided when the whole of the atomization assembly 11 and the liquid storage bullet 12 is separated from the main machine 10. After being separated, the connection between the liquid storage bullet 12 and the atomization assembly 11 can be conveniently released, and the operation convenience is increased.

[0080] When the connection between the atomization assembly 11 and the liquid storage bullet 12 is released, the atomization assembly 11 can be pulled to overcome the friction force between the needle 111 and the elastic sealing cover 123, and then the atomization assembly 11 is detached, and the elastic sealing cover 123 returns to its original state to reduce the probability of liquid leakage.

[0081] In some embodiments, the needle 111 is a metal piece, and the part of the atomization assembly 11 used for connecting with the needle 111 is injection molded on the needle 111.

[0082] Specifically, the needle 111 is a metal piece and can have certain structural strength to facilitate penetration through the elastic sealing cover 123.

[0083] Exemplarily, the needle 111 can be made of stainless steel or other high-strength metals.

[0084] It should be noted that the part of the atomization assembly 11 used for connecting with the needle 111 is injection molded on the needle 111, that is, the part of the atomization assembly 11 used for connecting with the needle 111 is connected with the needle 111 by injection molding. Specifically, the needle 111 is fixed in a mold, and then molten plastic is injected into the mold to wrap the connecting part of the needle 111, and after cooling, the plastic is tightly combined with the needle 111 to form an integrated component.

[0085] In this embodiment, the part of the atomization assembly 11 used for connecting with the needle 111 is injection molded on the needle 111, which can increase the sealing performance and reduce the probability of overflow of the aerosol generating medium from the part of the atomization assembly 11 used for connecting with the needle 111, thereby increasing the atomization reliability.

[0086] In some embodiments, referring to Figure 5 , the bottom side of the atomization assembly 11 has a plug-in cavity 11e, and the needle 111 extends into the plug-in cavity 11e from the top side of the plug-in cavity 11e, and the liquid storage bullet 12 is inserted into the plug-in cavity 11e from the bottom side of the plug-in cavity 11e.

[0087] In this embodiment, when the atomization assembly 11 is docked with the liquid storage bullet 12, the liquid storage bullet 12 is inserted into the plug-in cavity 11e from the bottom side of the plug-in cavity 11e, and contacts the needle 111 during the insertion process and is pierced by the needle 111. In this way, the docking is convenient, the plug-in cavity 11e can guide the movement of the liquid storage bullet 12 and facilitate accurate docking of the liquid storage bullet 12 with the needle 111. In the embodiment in which the part of the atomization assembly 11 used for connecting with the needle 111 is injection molded on the needle 111, the position of the needle 111 is fixed, and the liquid storage bullet 12 can be accurately docked with the needle 111 without positioning when being inserted into the plug-in cavity 11e from the bottom side.

[0088] In some embodiments, the atomization assembly 11 includes a cover unit 112 and an atomization core 113, the cover unit 112 is detachably connected with the main machine 10, the cover unit 112 surrounds the outer periphery of the atomization core 113, and the atomization core 113 is used for atomizing the aerosol generating medium discharged by the liquid storage bullet 12; the whole of the atomization core 113 is detachably connected with the cover unit 112, so that the atomization core 113 can be removed from the cover unit 112 as a whole.

[0089] In this embodiment, the cover unit 112 can provide structural support for the atomization core 113, and the whole of the atomization core 113 is detachably connected with the cover unit 112, which can be conveniently removed from the cover unit 112 for cleaning and replacement. By detachably connecting the cover unit 112 with the main machine 10, the connection firmness can be improved and the damage to the atomization core 113 can be reduced. At the same time, when replacement is needed, only the atomization core 113 needs to be replaced, thereby reducing the use cost.

[0090] The detachable connection manner of the cover unit 112 and the atomizing core 113 can be threaded connection, buckle connection, etc., which is not limited herein.

[0091] In some embodiments, referring to Figure 4 and Figure 7 , the outer periphery of one end of the cover unit 112 close to the host 10 is provided with a plurality of first clamping structures 112a, and the host 10 is provided with a second clamping structure 10d. The first clamping structure 112a has an unlocking position and a locking position, and the cover unit 112 can rotate relative to the host 10 to switch the first clamping structure 112a and the second clamping structure 10d between the unlocking position and the locking position.

[0092] The detachable connection of the cover unit 112 and the host 10 unit can be achieved by the butt joint of the first clamping structure 112a and the second clamping structure 10d. Specifically, when the cover unit 112 and the host 10 are initially butt jointed, the first clamping structure 112a is in the unlocking position. At this time, the first clamping structure 112a is rotated from the unlocking position to the locking position by rotating the cover unit 112, so as to realize the locking of the first clamping structure 112a and the second clamping structure 10d, and complete the butt joint of the host 10 and the cover unit 112. In the locking position, the cover unit 112 and the host 10 are stably connected and will not loosen. When it is needed to disengage the cover unit 112 and the host 10, the cover unit 112 is reversely rotated to switch the first clamping structure 112a from the locking position to the unlocking position, so as to facilitate the separation of the cover unit 112 from the host 10.

[0093] The rotation stroke of the cover unit 112 is not more than 50°, for example, 50°, 45°, 43°, 41°, 40°, 38°, 34°, 30°, 27°, 24°, 20°, 15°, 10°, 3°, etc.

[0094] It can be understood that the rotation stroke of the cover unit 112 is the angle range of the rotation of the cover unit 112 relative to the host 10 between the unlocking position and the locking position.

[0095] In this embodiment, the installation and disassembly operation can be easily performed through a small rotation stroke, which is convenient and reliable to operate without the need of additional tools.

[0096] In some embodiments, the rotation stroke of the cover unit 112 is 15°-30°, for example, 15°, 15°, 15°, 15°, 15°, 15°, 15°, 15°, 15°, 15°, 30°, etc.

[0097] In this embodiment, the rotation stroke of the cover unit 112 is relatively appropriate, which further increases the disassembly convenience between the host 10 and the cover unit 112.

[0098] In some embodiments, referring to Figures 4 to 7 , the host 10 comprises a tube shell 101, the cover unit 112 comprises an outer cover 1121 and an inner cover 1122 connected with each other, the inner cover 1122 is arranged inside the outer cover 1121, the outer cover 1121 is in abutment with the end face of the tube shell 101, a part of the inner cover 1122 extends into the tube shell 101, the first clamping structure 112a is formed on the outer periphery of the inner cover 1122, and the second clamping structure 10d is formed on the inner wall of the tube shell 101.

[0099] Specifically, the tube shell 101 can serve as an appearance component of the host 10 and can accommodate internal components.

[0100] In this embodiment, the second clamping structure 10d is formed on the inner wall of the tube shell 101, the first clamping structure 112a is formed on the outer periphery of the inner cover 1122, and the outer cover 1121 is arranged outside the inner cover 1122, that is, the abutment of the first clamping structure 112a and the second clamping structure 10d can be hidden inside the atomization device 1, thereby increasing the appearance aesthetics of the atomization device 1. The outer cover 1121 is in abutment with the end face of the tube shell 101, and the outer cover 1121 can provide external protection for the inner cover 1122, increase the appearance neatness of the atomization device 1, and reduce the probability of dust and impurities entering the tube shell 101 or the atomization assembly 11.

[0101] In some embodiments, the outer cover 1121 is a one-piece metal piece, and the inner cover 1122 is a one-piece plastic piece.

[0102] That is, the outer cover 1121 is integrally formed, and the inner cover 1122 is integrally formed. The outer cover 1121 and the inner cover 1122 can be a split structure.

[0103] In this embodiment, the outer cover 1121 is a one-piece metal piece, which can have sufficient strength to prevent external impact and wear, and the metal piece can also increase the appearance aesthetics of the atomization device 1, and the inner cover 1122 is a one-piece plastic piece, which can reduce production costs and facilitate molding, and also make the entire atomization device 1 more portable.

[0104] In some embodiments, referring to Figure 5 , the atomization assembly 11 further comprises a base 114, the base 114 is formed with a plug-in cavity 11e, and the base 114 is injection-molded connected with the needle 111 of the metal piece.
