[0026] 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.

[0027] The host module 10 includes a host housing 11 , a power supply assembly 13 and an air compressor 12 . The power supply assembly 13 is located in the host housing 11 and is electrically connected to the air compressor 12 .

[0028] The main housing 11 has a receiving cavity 11 a . A portion of the main housing 11 is opened to form a mounting opening 11 b . The mounting opening 11 b is communicated with the receiving cavity 11 a .

[0029] The air compressor 12 has an air inlet 12a and an air outlet 12b. The area of ​​the air compressor 12 with the air inlet 12a is located in the accommodating cavity 11a to communicate with the outside through the gap of the main body shell 11, and the area of ​​the air compressor 12 with the air outlet 12b is located in the installation port 11b.

[0030] The atomizer module 20 includes an atomizing shell 22 and a nozzle 21 arranged on the atomizing shell 22. The atomizing shell 22 has an air channel 20b and a liquid storage chamber 20a. One end of the air channel 20b is connected to the air outlet 12b, and the nozzle 21 is connected to the other end of the air channel 20b and the liquid storage chamber 20a respectively, so that the airflow from the air compressor 12 atomizes the atomized liquid from the liquid storage chamber 20a to generate an aerosol.

[0031] Specifically, the electronic atomization device of the embodiments of the present application can be any type of atomization device, such as a scalp atomization drug delivery device, wherein the atomized liquid stored in the electronic atomization device is a drug solution. In another example, the electronic atomization device is an electronic cigarette, wherein the atomized liquid stored in the electronic atomization device is tobacco oil.

[0032] The host module 10 is the host part of the electronic atomization device, and can output high-speed airflow to the nozzle 21 of the electronic atomization device through the air compressor 12 arranged inside the host housing 11.

[0033] Specifically, the air outlet 12b of the air compressor 12 is connected to the airway, thereby providing a high-speed airflow to the nozzle 21. The atomized liquid in the liquid storage chamber 20a is transmitted to the nozzle 21 and atomized by the high-speed airflow provided by the air compressor 12 to generate an aerosol.

[0034] The air compressor 12 in the embodiment of the present application refers to a device capable of compressing gas, such as an air pump.

[0035] The air inlet 12 a of the air compressor 12 is an air flow inlet for external air to enter the air compressor 12 .

[0036] The air outlet 12b of the air compressor 12 is an air flow outlet for outputting high-speed air flow.

[0037] The area of ​​the air compressor 12 with the air inlet 12a is located within the accommodating chamber 11a. In other words, the air inlet 12a of the air compressor 12 is not external to the main body housing 11, but is instead internally located within the accommodating chamber 11a. By locating the air inlet 12a within the accommodating chamber 11a, rather than extending to the outer surface of the main body housing 11 or directly to the exterior of the main body housing 11, the risk of external liquids (such as the atomized liquid in the electronic atomization device) entering the interior of the air compressor 12 through the air inlet 12a can be greatly reduced.

[0038] It is understandable that the air inlet 12 a of the air compressor 12 still needs to be connected to the outside world so that the outside air flow can enter the air compressor 12 through the air inlet 12 a.

[0039] The air inlet 12 a of the air compressor 12 is connected to the outside through a gap in the main body housing 11 .

[0040] It should be noted that the housing cavity 11a of the mainframe housing 11 is not a completely enclosed cavity. Small gaps exist within the mainframe housing 11 itself. For example, the mainframe housing 11 includes multiple walls, each of which encloses the housing cavity 11a. At the junctions between the walls, portions of adjacent walls are separated to create gaps for external airflow into the housing cavity 11a.

[0041] The number of gaps on the main housing 11 can be set according to actual conditions.

[0042] For example, the main housing 11 has a plurality of gaps, and the sum of the areas of the gaps is greater than or equal to 1.5 mm. 2 Thus, it is possible to ensure that external air enters the accommodating chamber 11a through the gap and then enters the air compressor 12 through the air inlet 12a.

[0043] The mounting port 11b of the main housing 11 is a connecting port for the air outlet 12b to extend out of the accommodating chamber 11a. Thus, by forming the mounting port 11b, the air outlet 12b of the air compressor 12 can be conveniently placed outside the accommodating chamber 11a, thereby facilitating the high-speed airflow provided by the air compressor 12 to flow out of the main housing 11 through the air outlet 12b, and then facilitate the nozzle 21 to receive it.

[0044] At the same time, it should be noted that since the air outlet 12b is used to allow air to flow out of the air compressor 12, while the air inlet 12a is used to allow air to flow into the air compressor 12, the risk of external liquid entering the air compressor 12 through the air outlet 12b is lower than that of the air inlet 12a. Therefore, compared with the air outlet 12b being built in, the internalization of the air inlet 12a can better reduce the risk of liquid entering the air compressor 12.

[0045] The specific sizes of the air inlet 12a and the air outlet 12b can be set according to actual conditions.

[0046] For example, the inner diameter of the air inlet 12a is greater than or equal to 0.7 mm and less than or equal to 1.5 mm. For example, the inner diameter of the air inlet 12a is 0.7 mm, 1 mm, or 1.5 mm. The air inlet 12a having a size within the above range can enable the air compressor 12 to have a better air intake effect.

[0047] For another example, the inner diameter of the air outlet 12b is greater than or equal to 0.7 mm and less than or equal to 1.5 mm. For example, the inner diameter of the air outlet 12b is 0.7 mm, 1 mm, or 1.5 mm. The air outlet 12b having a size within the above range can enable the air compressor 12 to have a better air outlet effect.

[0048] Furthermore, the specific shapes of the air inlet 12a and the air outlet 12b can also be set according to actual conditions.

[0049] For example, the air inlet 12a is a circular hole, a square hole, or a rectangular hole.

[0050] For another example, the air outlet 12b is a circular hole, a square hole, or a rectangular hole.

[0051] In the electronic atomization device provided in the embodiment of the present application, the main housing 11 of the main module 10 has a accommodating chamber 11a, and a part of the main housing 11 is open to form a mounting port 11b, and the mounting port 11b is connected to the accommodating chamber 11a. The air compressor 12 has an air inlet 12a and an air outlet 12b. The area where the air compressor 12 has the air inlet 12a is located in the accommodating chamber 11a to communicate with the outside world through the gap of the main housing 11, and the area where the air compressor 12 has the air outlet 12b is located in the mounting port 11b. Thus, the air inlet 12a can be built into the accommodating chamber 11a to avoid the air inlet 12a being directly exposed to the outside of the main housing 11, thereby reducing the risk of external liquid directly entering the interior of the air compressor 12 through the air inlet 12a, and thus preventing the interior of the air compressor 12 from being contaminated or damaged. At the same time, the air inlet 12a built into the accommodating chamber 11a can communicate with the outside world through the gap of the main body shell 11, so that external air can enter the accommodating chamber 11a through the gap of the main body shell 11, and then can supply air to the air compressor 12 through the air inlet 12a. In this way, the risk of liquid intrusion into the air compressor 12 can be reduced while the normal air intake of the air compressor 12 is not affected.

[0052] In one embodiment, please refer to Figure 3 The main housing 11 includes a connecting end wall 111 having the mounting opening 11b. The opening of the air inlet 12a faces the connecting end wall 111. The air inlet 12a is offset from the mounting opening 11b and is spaced apart from the connecting end wall 111.

[0053] Specifically, a portion of the connecting end wall 111 at the end of the main housing 11 is opened to form a mounting opening 11b. The air outlet 12b extends to the mounting opening 11b, thereby facilitating air supply from the air compressor 12 to the nozzle 21 through the mounting opening 11b.

[0054] The air inlet 12a is built into the accommodating cavity 11a, and the opening of the air inlet 12a is not directly facing the outside of the main body housing 11, but facing the connecting end wall 111. In addition, the air inlet 12a and the installation port 11b are staggered, that is, the air inlet 12a and the installation port 11b are staggered. As a result, the connecting end wall 111 can form a certain shielding for the air inlet 12a to reduce the risk of external liquid directly entering the air compressor 12 through the air inlet 12a. At the same time, since the air inlet 12a and the connecting end wall 111 are spaced apart, it is possible to avoid the connecting end wall 111 completely blocking the air inlet 12a, thereby preventing the problem of poor air intake at the air inlet 12a.

[0055] It should be noted that the specific formation position of the gap in the host housing 11 is not limited.

[0056] For example, the gap in the main housing 11 is arranged to avoid the connection end wall 111. Thus, the gap in the main housing 11 can be arranged as much as possible on the peripheral side of the main housing 11, or at the end of the main housing 11 opposite the connection end wall 111. This can further reduce the risk of external liquid entering the air compressor 12 through the air inlet 12a.

[0057] In one embodiment, please refer to Figure 4 The air compressor 12 has an air compressor end face 121 at one end close to the mounting port 11b. The air compressor end face 121 has an air inlet area and an air outlet area. The air inlet 12a is located in the air inlet area, and the air outlet 12b is located in the air outlet area. The air outlet area protrudes relative to the air inlet area so that the air outlet 12b extends into the mounting port 11b.

[0058] Specifically, the air inlet 12a and the air outlet 12b are both arranged on the end face of the air compressor 12 close to the installation port 11b, thereby allowing the air flow entering the air compressor 12 from the air inlet 12a to flow out from the air outlet 12b more conveniently.

[0059] The air inlet region is a region on the air compressor end surface 121 for forming the air inlet 12 a , and the air outlet region is a region on the air compressor end surface 121 for forming the air outlet 12 b .

[0060] By making the air outlet area protrude, the air outlet 12b can be extended into the installation opening 11b, thereby facilitating air outlet 12b to discharge air.

[0061] Thus, a certain length difference is formed between the air inlet region and the air outlet region in the longitudinal direction, which can also facilitate the air inlet 12a to be built into the accommodating cavity 11a.

[0062] In one embodiment, please refer to Figure 4 and Figure 5 The air inlet area is recessed to form a recessed space 121 a , and the hole wall of the air inlet 12 a extends into the recessed space 121 a so as to be spaced apart from the connecting end wall 111 .

[0063] Specifically, the air intake area is recessed relative to other areas of the air compressor end face 121, thereby forming a recessed space 121a. By forming the recessed space 121a and setting the hole wall forming the air inlet 12a within the recessed space 121a, it can be ensured that the hole wall of the air inlet 12a and the connecting end wall 111 are spaced apart from each other, thereby avoiding the connecting end wall 111 and the air inlet 12a from fitting together and blocking the air inlet 12a, thereby ensuring a better air intake effect.

[0064] In one embodiment, at least a portion of the outer circumference of the air compressor 12 is spaced apart from the main housing 11 to form a separation space, and the recessed space 121a extends along one side of the circumference to the outer circumference of the air compressor 12 to communicate with the separation space.

[0065] Specifically, the outer peripheral surface of the air compressor 12 can be partially spaced apart from the main housing 11, and a space is formed at the space. Of course, the outer peripheral surface of the air compressor 12 can be fully spaced apart from the main housing 11, and a space is formed at the space.

[0066] Moreover, by opening one side of the recessed space 121a to communicate with the partition space, it is convenient for external airflow to enter the accommodating cavity 11a through the gap of the main housing 11, pass through the partition space and the recessed space 121a, and then enter the air compressor 12 from the air inlet 12a, thereby providing an air intake effect for the air compressor 12.

[0067] In one embodiment, the host module 10 further includes a control component, and the power supply component is electrically connected to the control component and the air compressor 12 respectively. The power supply component supplies power to the air compressor 12 so that the air compressor 12 provides high-speed airflow to the atomizer module 20.

[0068] The specific structure of the control assembly can be set according to actual conditions. For example, the control assembly includes a key switch, an indicator light, and a PCB board. The indicator light is mounted on the PCB board. The indicator light, the power supply assembly, and the PCB board are electrically connected. Pressing the key switch can activate the electronic atomization device, causing the power supply assembly to supply power to the air compressor 12, thereby providing high-speed airflow to the atomizer module 20.
