DETAILED DESCRIPTION

[0030] An embodiment of the present application provides an electronic atomization device, see Figure 1 and Figure 2 The electronic atomization device includes a host module 10 and an atomizer module 20.

[0031] The host module 10 includes a power supply assembly 12 and an air compressor 11 , and the power supply assembly 12 and the air compressor 11 are electrically connected.

[0032] The atomizer module 20 includes an atomizing body 21 , a dust cover 22 and a sealing member 23 .

[0033] The atomizing body 21 includes a shell 212 and a nozzle 211 arranged on the shell 212, the nozzle 211 has a mist outlet, and the shell 212 has an air channel 21c and a liquid storage chamber 21b; the air compressor 11 is connected to one end of the air channel 21c, and the nozzle 211 is respectively connected to the other end of the air channel 21c and the liquid storage chamber 21b, so that the airflow from the air compressor 11 atomizes the medium stored in the liquid storage chamber 21b to generate an aerosol, and flows out from the mist outlet of the nozzle 211.

[0034] The dust cover 22 has an installation cavity 22a, one end of which is open to form an installation entrance. The dust cover 22 is detachably connected to the housing 212 so that the nozzle 211 can be detachably installed in the installation cavity 22a through the installation entrance.

[0035] The sealing member 23 is located in the installation cavity 22a and is connected to the dust cover 22. The dust cover 22 moves relative to the housing 212 to drive the sealing member 23 to switch between blocking the mist outlet and avoiding the mist outlet.

[0036] Specifically, the electronic atomization device of the embodiment of the present application can be any type of atomization device, such as a scalp atomization drug delivery device, wherein the medium stored in the atomizer module 20 is a drug solution, such as minoxidil. In another example, the electronic atomization device is an electronic cigarette, wherein the medium stored in the atomizer module 20 is tobacco oil.

[0037] Specifically, the air compressor 11 refers to a device capable of compressing gas, such as an air pump.

[0038] The air compressor 11 is electrically connected to the power supply assembly 12, which drives the air compressor 11 to provide high-speed airflow to the nozzle 211. The atomizer module 20 is an atomizing component in the electronic atomization device that can atomize the medium to generate an aerosol.

[0039] The housing 212 can store a medium. The medium in the liquid storage chamber 21b is transmitted to the nozzle 211 and atomized under the action of the high-speed airflow provided by the air compressor 11, so that the medium is atomized to generate an aerosol.

[0040] The nozzle 211 has a mist outlet, and the aerosol generated by the atomization of the medium can reach the outside of the atomizer module 20 through the mist outlet of the nozzle 211.

[0041] The nozzle 211 enters the installation cavity 22 a of the dust cover 22 through the installation entrance. When the dust cover 22 is connected to the housing 212 , the sealing member 23 in the dust cover 22 blocks the mist outlet of the nozzle 211 of the atomizing body 21 .

[0042] The dust cover 22 and the housing 212 are connected in any manner. For example, the dust cover 22 and the housing 212 are connected by a buckle. In another example, the dust cover 22 and the housing 212 are connected by a thread.

[0043] The position of the sealing member 23 in the installation cavity 22a of the dust cover 22 is not limited. For example, the sealing member 23 is located on the side wall of the dust cover 22. For another example, the sealing member 23 is located on the inner wall of the dust cover 22 away from the installation entrance.

[0044] The connection method between the sealing member 23 and the dust cover 22 is not limited.

[0045] For example, the sealing member 23 is detachably engaged in the mounting cavity 22 a of the dust cover 22 .

[0046] For another example, the sealing member 23 is attached to the mounting cavity 22 a of the dust cover 22 by 3M adhesive so as to be fixedly connected to the dust cover 22 .

[0047] The material type of the sealing member 23 is not limited, as long as it can block the mist outlet when the dust cover 22 is connected to the housing 212. For example, the sealing member 23 is an elastic member.

[0048] When the user installs the dust cover 22 on the housing 212, the seal 23 can block the mist outlet of the nozzle 211. When the user detaches the dust cover 22 from the housing 212, the seal 23 can separate from the nozzle 211, thereby avoiding the mist outlet.

[0049] An embodiment of the present application provides an electronic atomization device, comprising a host module 10 and an atomizer module 20. The host module 10 comprises a power supply assembly 12 and an air compressor 11, and the power supply assembly 12 and the air compressor 11 are electrically connected. The atomizer module 20 comprises an atomizing body 21, a dust cover 22 and a seal 23. The atomizing body 21 comprises a shell 212 and a nozzle 211 arranged on the shell 212, the nozzle 211 having a mist outlet, and the shell 212 having an airway 21c and a liquid storage chamber 21b; the air compressor 11 is connected to one end of the airway 21c, and the nozzle 211 is respectively connected to the other end of the airway 21c and the liquid storage chamber 21b, so that the airflow from the air compressor 11 atomizes the medium stored in the liquid storage chamber 21b to generate an aerosol, and flows out from the mist outlet of the nozzle 211. The dust cover 22 has a mounting cavity 22a, one end of which can be opened to form an installation entrance. The dust cover 22 is detachably connected to the housing 212 so that the nozzle 211 can be detachably installed in the mounting cavity 22a through the installation entrance. The seal 23 is located in the mounting cavity 22a and is connected to the dust cover 22. The dust cover 22 moves relative to the housing 212 to drive the seal 23 to switch between blocking the mist outlet and avoiding the mist outlet. On the one hand, by blocking the nozzle 211 of the atomizer module 20 with the seal 23, the medium can be effectively prevented from leaking into the air from the mist outlet, and the medium can be prevented from crystallizing due to exposure, thereby clogging the nozzle 211. This ensures that the medium maintains an appropriate amount of atomization during the atomization process, prevents the atomization effect from being reduced or completely unable to atomize due to crystallization blockage, and ensures the continuous and stable function of the atomizer module 20. At the same time, it can also prevent outside air from entering the liquid storage chamber 21b through the mist outlet, thereby contaminating the medium. On the other hand, by connecting the sealing member 23 to the dust cover 22, the sealing member 23 can move synchronously with the movement of the dust cover 22 relative to the housing 212, thereby more effectively blocking or avoiding the mist outlet.

[0050] In one embodiment, please refer to Figure 2 and Figure 4 The dust cover 22 includes a mounting wall 221 located on the side of the mounting cavity 22a facing away from the mounting entrance. The mounting wall 221 has an inner wall surface, at least a portion of which extends toward the mounting entrance to enclose a receiving space, within which the seal 23 is disposed. Thus, installing the seal 23 within the receiving space provides stability for the seal 23's installation and allows the seal 23 to accurately seal the mist outlet of the nozzle 211 when the dust cover 22 is connected to the housing 212.

[0051] Specifically, the installation wall 221 refers to an area on the dust cover 22 that is opposite to the installation entrance.

[0052] Part of the wall surface of the installation wall 221 located in the accommodating cavity extends toward the installation entrance to form an accommodating space for placing the sealing member 23 .

[0053] It is understandable that the shape of the area of ​​the inner wall of the installation wall 221 extending toward the installation entrance is not limited, as long as it can form an accommodating space and cooperate with the seal 23 so that the seal 23 is installed in the accommodating space.

[0054] For example, the annular area of ​​the inner wall surface of the installation wall 221 extends toward the installation entrance to form an annular accommodating space.

[0055] For another example, a plurality of regions of the inner wall surface of the installation wall 221 extend toward the installation entrance at intervals to form an accommodation space.

[0056] The manner in which the sealing member 23 is disposed in the accommodation space is not limited.

[0057] For example, a connecting buckle 224 that matches the sealing member 23 is provided on the side wall surface 223 of the accommodating space. The sealing member 23 and the connecting buckle 224 cooperate with each other to be installed in the accommodating space.

[0058] For another example, the sealing member 23 is installed in the accommodating space by interference fit with the side wall surface 223 of the accommodating space.

[0059] In one embodiment, please refer to Figure 2 and Figure 4 The inner wall surface of the mounting wall 221 includes a mounting wall surface and a side wall surface 223 located within the accommodating space. The mounting wall surface is located on the side of the accommodating space away from the mounting entrance. A portion of the mounting wall surface protrudes toward the nozzle 211 to form a protrusion 222. The protrusion 222 and at least a portion of the side wall surface 223 are separated to form an accommodating groove 221a. The end of the sealing member 23 facing away from the nozzle 211 is fixed in the accommodating groove 221a to be removably connected to the dust cover 22. Thus, the engagement of the sealing member 23 with the accommodating groove 221a can ensure a more secure connection between the sealing member 23 and the dust cover 22.

[0060] It can be understood that since part of the inner wall surface of the installation wall body 221 extends to form an accommodating space, the accommodating space has an installation wall surface and a side wall surface 223, that is, the installation wall surface and the side wall surface 223 are both part of the inner wall surface.

[0061] Specifically, the installation wall is located on a side of the accommodating space away from the installation entrance, that is, the installation wall is arranged opposite to the installation entrance.

[0062] The mounting wall surface can be formed by protruding a central region to form a protrusion 222, whereby the outer periphery of the protrusion 222 is spaced apart from the side wall surface 223, thereby forming the receiving groove 221a. Of course, the protrusion 222 can also be formed by one side being in contact with the side wall surface 223 and the other side being spaced apart from the side wall surface 223, thereby forming the receiving groove 221a.

[0063] The shape and size of the sealing member 23 are set according to the shape and size of the receiving groove 221a to ensure that the sealing member 23 can be well fixed in the receiving groove 221a and the atomizer module 20 will not fall out of the receiving groove 221a during use.

[0064] The specific manner in which the sealing member 23 is clamped in the receiving groove 221 a is not limited.

[0065] For example, the sealing member 23 is provided with a buckle or a protrusion, so that it can be snapped into the receiving groove 221a to achieve the fixation of the sealing member 23 and the receiving groove 221a.

[0066] For another example, when the sealing member 23 is made of an elastic material, the sealing member 23 can be pressed into the receiving groove 221 a by pressure, thereby achieving fixation between the sealing member 23 and the receiving groove 221 a.

[0067] In one embodiment, please refer to Figure 4 The outer circumferential surface of the protrusion 222 is spaced apart from the sidewall surface 223. The receiving groove 221a is an annular groove. The seal 23 has a receiving cavity. The end of the receiving cavity facing away from the nozzle 211 is open, so that the seal 23 forms an open end 231. The end of the receiving cavity near the nozzle 211 is sealed, so that the seal 23 forms a sealed end 232. The open end 231 is locked in the receiving groove 221a. Therefore, by locking the open end 231 of the seal 23 in the receiving groove 221a, the connection between the seal 23 and the dust cover 22 can be more firmly established.

[0068] Specifically, the sealing member 23 is connected to the accommodating groove 221 a through the open end 231 , and blocks the nozzle 211 through the sealing end 232 when the dust cover 22 is connected to the housing 212 .

[0069] The shape of the protrusion 222 is not limited, as long as the outer circumferential surface of the protrusion 222 can cooperate with the side wall surface 223 to form the receiving groove 221a. For example, the protrusion 222 is cylindrical. In another example, the protrusion 222 is conical and cooperates with the side wall surface 223 to form annular receiving grooves 221a of different diameters, which helps guide or position the seal 23.

[0070] There is no limitation on the manner in which the opening end 231 is locked in the receiving groove 221 a.

[0071] For example, the opening end 231 is designed with a specific shape, such as a flange or an edge, and can be directly inserted into the receiving groove 221a, relying on friction or shape matching to maintain the engagement with the receiving groove 221a.

[0072] For another example, the opening end 231 and the receiving groove 221 a are locked with the receiving groove 221 a through interference fit.

[0073] In one embodiment, please refer to Figure 2 and Figure 5 The seal 23 is an elastic body. When the dust cover 22 is installed on the housing 212, the seal 23 abuts against the nozzle 211 to seal the mist outlet through elastic deformation. In this way, the seal 23 can fit more closely with the mist outlet to form a good seal.

[0074] Specifically, the material type of the sealing member 23 is not limited as long as it can produce elastic deformation.

[0075] For example, the seal 23 can be made of one of silicone, air-rubber, and fluorosilicone. This allows the seal 23 to better seal the mist outlet. Furthermore, the seal 23 can have better corrosion resistance. When the seal 23 seals the mist outlet, it will not be damaged by corrosion when in contact with the medium in the liquid storage chamber 21b.

[0076] In one embodiment, please refer to Figure 2 and Figure 5 The end surface of the sealing member 23 near the mist outlet is one of a flat surface and an arc surface. Thus, the contact area between the sealing member 23 and the mist outlet can be maximized, thereby improving the sealing effect.

[0077] In one embodiment, the hardness of the seal 23 is greater than or equal to 40 Shore A and less than or equal to 80 Shore A. For example, the hardness of the seal 23 is 40 Shore A, 60 Shore A, or 80 Shore A. Thus, using a hardness within the above range can provide the seal 23 with good elasticity and structural strength, allowing it to adapt to irregular surfaces and slight dimensional changes in the mist outlet, thereby improving the sealing effect.

[0078] In one embodiment, please refer to Figure 2 、 Figure 2 and Figure 4 One of the housing 212 and the dust cover 22 has a connecting slot 21a, and the other has a connecting buckle 224 that engages with the connecting slot 21a. Thus, the connection between the housing 212 and the dust cover 22 is stable through the engagement of the connecting buckle 224 with the connecting slot 21a.

[0079] Specifically, the housing 212 may have a connecting slot 21a, and the dust cover 22 may have a connecting buckle 224. Depending on actual conditions, the housing 212 may have a connecting buckle 224, and the dust cover 22 may have a connecting slot 21a.

[0080] It is understandable that the shape and size of the connecting buckle 224 match the connecting slot 21 a to achieve a snap fit.

[0081] The snap-fitting between the connecting buckle 224 and the connecting slot 21 a is detachable, allowing the user to conveniently install and remove the dust cover 22 .

[0082] Through the precise matching of the connecting slot 21 a and the connecting buckle 224 , the sealing member 23 can accurately block the mist outlet of the nozzle 211 , thereby improving the sealing effect.

[0083] In one embodiment, please refer to Figure 3 At least a portion of the end of the housing 212 facing away from the nozzle 211 is recessed to form a connecting slot 21a. At the installation entrance, at least a portion of the inner wall of the dust cover 22 extends inwardly toward the installation entrance to form a connecting buckle 224. Thus, the design of the connecting slot 21a and the connecting buckle 224 ensures a stable connection, maintaining a secure connection between the housing 212 and the dust cover 22 even under vibration or impact.

[0084] It is understandable that at least a portion of the inner wall of the dust cover 22 extends into the installation entrance to form a connecting buckle 224 . The connecting buckle 224 may be a convex block or a convex strip.

[0085] There may be a plurality of protrusions, which are arranged at intervals along the inner wall of the dust cover 22 in the circumferential direction.

[0086] The convex strips extend along the circumferential direction of the inner wall of the dust cover 22 , and the length of the convex strips is less than or equal to the circumferential length of the inner wall of the dust cover 22 .

[0087] The end of the housing 212 facing away from the nozzle 211 may be partially recessed corresponding to the protrusion or rib to form a connecting slot 21a, with the length of the connecting slot 21a being greater than or equal to the length of the protrusion or rib. Alternatively, the entire area may be recessed to form the connecting slot 21a.

[0088] For example, the housing 212 has a plurality of connecting slots 21a, each of which is spaced apart along the circumference of the housing 212. The dust cover 22 includes a plurality of spaced-apart connecting buckles 224, each of which engages with a corresponding connecting slot 21a. Thus, the combination of the multiple slots and buckles provides multiple fixing points, increasing the stability of the connection between the dust cover 22 and the housing 212 and reducing the risk of the dust cover 22 falling off due to vibration or accidental collision.
