[0037] The present application provides an atomization device 1.

[0038] Please refer to Figures 1 to 3, the atomization device 1 comprises a main machine 10, a cartridge 12 for storing aerosol generating medium and an atomization assembly 11.

[0039] It should be noted that the atomization device 1 of the embodiment 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 treatment, beauty, health care, electronic atomization, etc. For example, the atomization device 1 can be a scalp administration atomization device 1. The aerosol generating medium can adopt a liquid medium, such as an oil containing aroma components, a medicinal liquid, etc.

[0040] The host 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.

[0041] 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.

[0042] Specifically, the host 10 has a cartridge accommodating cavity 10a, and the liquid storage cartridge 12 is accommodated in the cartridge accommodating cavity 10a.

[0043] The cartridge accommodating cavity 10a is used to provide space for the liquid storage cartridge 12, so as to provide protection for the liquid storage cartridge 12 and reduce the influence of external impact on the liquid storage cartridge 12.

[0044] The atomization assembly 11 is detachably arranged at the first end of the host 10 along a first direction, and is used to atomize the aerosol generating medium discharged by the liquid storage cartridge 12. The first direction is parallel to the axial direction of the atomization device 1.

[0045] It can be understood that in the embodiment, the first direction, the axial direction of the atomization device 1 and the top-bottom direction can be consistent.

[0046] Specifically, the atomization assembly 11 is detachably connected with the host 10, that is, when the atomization assembly 11 and the host 10 are connected, the connection part remains stable and is not easy to be loosened or separated. When it is necessary to separate the atomization assembly 11 from the host 10, the connection relationship between the atomization assembly 11 and the host 10 can be released, so as to take out the atomization assembly 11.

[0047] The detachable connection can enable the atomization assembly 11 to be connected with and detached from the host 10 as a whole.

[0048] The specific manner of detachable connection is not limited, and exemplarily can be threaded connection, buckle connection, plug-in connection, etc., which are not limited herein.

[0049] The liquid storage cartridge 12 is detachably connected with the atomization assembly 11, so that when the whole of the atomization assembly 11 is separated from the host 10, the whole of the atomization assembly 11 carries the liquid storage cartridge 12 out of the cartridge accommodating cavity 10a.

[0050] Specifically, when the whole of the atomization assembly 11 is disconnected from the main machine 10 to separate the atomization assembly 11 from the main machine 10, due to the connection relationship between the liquid storage bullet 12 and the atomization assembly 11, the atomization assembly 11 can carry the liquid storage bullet 12 out of the bullet body accommodating cavity 10a, and after being pulled out, the connection relationship between the liquid storage bullet 12 and the atomization assembly 11 is disconnected, so as to separate the liquid storage bullet 12 from the atomization assembly 11, thereby achieving the liquid supplement or replacement of the liquid storage bullet 12 and the cleaning or replacement of the atomization assembly 11, respectively.

[0051] Of course, during assembly, the atomization assembly 11 can be first connected with the liquid storage bullet 12, and then the whole of the atomization assembly 11 and the liquid storage bullet 12 is connected with the main machine 10, thereby increasing the installation stability.

[0052] The atomization device 1 provided by the embodiment of the present application can separate the atomization assembly 11 from the main machine 10 as a whole unit with the liquid storage bullet 12 when the whole of the atomization assembly 11 is separated from the main machine 10, and can also reduce the probability of leakage of the aerosol generating medium in the liquid storage bullet 12 when the liquid storage bullet 12 is pulled out alone, thereby being convenient and safe to operate and increasing the pulling-out stability. After the atomization assembly 11 and the liquid storage bullet 12 are pulled out, the atomization assembly 11 and the liquid storage bullet 12 are disconnected, thereby achieving the liquid supplement or replacement of the liquid storage bullet 12 and the cleaning or replacement of the atomization assembly 11, respectively, and the liquid storage bullet 12 and the atomization assembly 11 are convenient and reliable to disassemble and assemble.

[0053] In some embodiments, referring to FIG. 5, the 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 outside the atomization device 1, the liquid channel 11b is connected with the liquid outlet 11a and the liquid storage bullet 12, the liquid outlet 11a is used for spraying the aerosol generating medium, and the gas sprayed from the first gas outlet 11d is used for atomizing the aerosol generating medium sprayed from the liquid outlet 11a.

[0054] 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.

[0055] Specifically, the first gas outlet 11d is connected with the first gas channel 11c, the aerosol generating medium in the liquid storage bullet 12 is sprayed out through the liquid channel 11b and the liquid outlet 11a, and is combined with the gas sprayed out 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, so as to complete the atomization.

[0056] It should be noted that the liquid outlet 11a and the first gas outlet 11d are exposed outside the atomization device 1, which means that the liquid outlet 11a and the first gas outlet 11d can be seen from the outside, so that the aerosol generated after the aerosol generating medium is atomized can be exposed outside to be used.

[0057] 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, so as 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 into fine particles, forms an aerosol, and diffuses into the external environment for the user to use, and the atomization effect is good.

[0058] In some embodiments, referring to FIG. 2, the host 10 has a second gas channel 10b inside, and the end of the host 10 away from the atomization assembly 11 has an air inlet 10c for connecting to an external pressure source. The second gas channel 10b is used to guide the gas flow to the first gas channel 11c.

[0059] 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 the air inlet 10c, and the 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, dispersing the aerosol generating medium into finer particles and improving the atomization effect.

[0060] It can be understood that the external pressure source can be a gas pump (also known as a compressor or air compressor).

[0061] It can be understood that the output pressure of the external pressure source can be adjusted to control the speed and intensity of the gas flow, and thus the atomization effect can be adjusted.

[0062] In some embodiments, referring to FIG. 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, and the bottle body 121 has an opening 121a at the end away from the atomization assembly 11. One end of the driving mechanism 102 extends into the bottle body 121 through the opening 121a and holds the sealing piston 122 in the 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.

[0063] Specifically, the bottle body 121 is configured to store the aerosol generating medium, and the sealing piston 122 is arranged in the bottle body 121. On one hand, the sealing piston 122 can be moved 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 seal the aerosol generating medium in the bottle body 121 from overflowing when the driving mechanism 102 is driven, thereby increasing the reliability of liquid supply.

[0064] In this embodiment, the aerosol generating medium in the liquid storage bullet 12 is driven to flow to the liquid outlet 11a by the cooperation of the driving mechanism 102 and the sealing piston 122, so as to realize continuous liquid supply. The sealing piston 122 can move at a stable speed, thereby increasing the stability of liquid supply reliability. Meanwhile, 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.

[0065] 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 configured 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.

[0066] That is, after the host 10 and the atomization assembly 11 establish a connection relationship, the detection piece triggers the detection unit to generate an in-place detection signal, that is, the atomization assembly 11 is assembled in place. The detection unit transmits the in-place detection signal to the control unit, and the control unit determines that the atomization assembly 11 is installed according to the in-place detection signal.

[0067] In this embodiment, the detection piece and the detection unit are used to detect whether the atomization assembly 11 is assembled and whether the atomization assembly 11 is assembled in place. In this way, the probability of missing the atomization assembly 11 after cleaning by the user can be reduced, and whether the atomization assembly 11 is assembled to the expected position can be confirmed, so that the atomization assembly 11 is installed more reliably and stably, and is less likely to be detached during work.

[0068] 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.

[0069] In some embodiments, the control unit is further configured to control the driving mechanism 102 to move to an initial position when the detection unit detects that the atomization assembly 11 is separated from the host 10.

[0070] It can be understood that the initial position refers to a position where the driving mechanism 102 is not subjected to a movement signal, that is, a position where the driving mechanism 102 is in contact with the sealing piston 122 but does not exert a driving force when the liquid storage bullet 12 is in a full-liquid state and is installed in the bullet body accommodating cavity.

[0071] In this embodiment, when the atomization assembly 11 is separated from the main machine 10, the atomization assembly 11 carries the liquid storage bullet 12 away from the main machine 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 reinstalled into the bullet accommodating cavity, the corresponding position of the driving mechanism 102 does not change, the driving mechanism 102 does not interfere with the installation of the liquid storage bullet 12, and the installation reliability is improved.

[0072] In some embodiments, referring to FIGS. 5-7, 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 that penetrates through the elastic sealing cover 123. The needle 111 communicates the liquid channel 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 the friction force between the needle 111 and the elastic sealing cover 123.

[0073] Specifically, the elastic sealing cover 123 is used for sealing. When the liquid storage bullet 12 is not connected with the needle 111, the aerosol generating medium in the liquid storage bullet 12 is located in a closed space under the action of the elastic sealing cover 123 and the sealing piston 122, and does not overflow. The elastic sealing cover 123 is a structure with certain elastic properties. The needle 111 has a sharp end. The needle 111 can penetrate 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.

[0074] For example, the elastic sealing plug can be made of elastic materials such as rubber or silicone.

[0075] It can be understood that when the needle 111 penetrates through the elastic sealing cover 123, a large friction force can be generated due to the resilience and friction coefficient of the elastic sealing cover 123. The part where the needle 111 penetrates through the elastic sealing cover 123 can be tightly wrapped by the elastic sealing cover 123 to generate a friction force. Therefore, the detachable connection between the liquid storage bullet 12 and the atomization assembly 11 is achieved by the friction force.

[0076] In this embodiment, the cooperation of the needle 111 and the elastic sealing cover 123 not only realizes the communication between the liquid channel 11b and the aerosol generating medium in the bottle body 121, but also realizes the detachable connection between the liquid storage bullet 12 and the atomization assembly 11. This makes the connection between the atomization assembly 11 and the liquid storage bullet 12 more simple and convenient, and facilitates the liquid storage bullet 12 and the atomization assembly 11 to be separated from the main machine 10 without liquid leakage. 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 improved.

[0077] When the connection between the atomization assembly 11 and the liquid storage cartridge 12 is released, the atomization assembly 11 can be pulled to overcome the friction between the needle 111 and the elastic sealing cover 123, and then the atomization assembly 11 is removed, and the elastic sealing cover 123 returns to its original state, thereby reducing the probability of liquid leakage.

[0078] 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.

[0079] Specifically, the needle 111 is a metal piece, which can have a certain structural strength and facilitate the penetration of the elastic sealing cover 123.

[0080] Exemplarily, the needle 111 can be made of stainless steel or other high-strength metals.

[0081] 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, which means that 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.

[0082] 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, reduce the probability of overflow of aerosol generating medium from the part of the atomization assembly 11 used for connecting with the needle 111, and increase the reliability of atomization.

[0083] In some embodiments, referring to FIG. 5, the bottom side of the atomization assembly 11 has a plug-in cavity 11e, the needle 111 extends into the plug-in cavity 11e from the top side of the plug-in cavity 11e, and the liquid storage cartridge 12 is inserted into the plug-in cavity 11e from the bottom side of the plug-in cavity 11e.

[0084] In this embodiment, when the atomization assembly 11 is connected with the liquid storage cartridge 12, the liquid storage cartridge 12 is inserted into the plug-in cavity 11e from the bottom side of the plug-in cavity 11e, contacts the needle 111 during the insertion process, and is penetrated by the needle 111, so that the connection is convenient, the plug-in cavity 11e can guide the movement of the liquid storage cartridge 12, and the accurate connection between the liquid storage cartridge 12 and the needle 111 is facilitated. 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 cartridge 12 can be accurately connected with the needle 111 without positioning when being inserted into the plug-in cavity 11e from the bottom side.

[0085] In some embodiments, the atomization assembly 11 comprises 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 cartridge 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.

[0086] 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 and 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.

[0087] The detachable connection mode of the cover unit 112 and the atomization core 113 can be threaded connection, buckle connection, etc., which is not limited herein.

[0088] In some embodiments, referring to FIGS. 4 and 7, the outer periphery of one end of the cover unit 112 close to the main machine 10 is provided with a plurality of first clamping structures 112a, and the main machine 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 main machine 10 to switch the first clamping structure 112a and the second clamping structure 10d between the unlocking position and the locking position.

[0089] The detachable connection of the cover unit 112 and the main machine 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 main machine 10 are initially butt jointed, the first clamping structure 112a is in the unlocking position, at this time, the cover unit 112 is rotated to drive the first clamping structure 112a to rotate from the unlocking position to the locking position, thereby achieving the locking of the first clamping structure 112a and the second clamping structure 10d, completing the butt joint of the main machine 10 and the cover unit 112, and in the locking position, the cover unit 112 and the main machine 10 are stably connected and will not loosen. When the butt joint of the cover unit 112 and the main machine 10 needs to be released, the cover unit 112 is reversely rotated to switch the first clamping structure 112a from the locking position to the unlocking position, thereby facilitating the separation of the cover unit 112 from the main machine 10.

[0090] 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.
