[0067] In this application, the orientation or position relationship between the "first direction" and the "second direction" is based on the attached Figure 3 The directions or positional relationships shown in the figure are based on the directions or positional relationships in the third direction. Figure 9 The directions or positional relationships shown in the figure are based on the directions or positional relationships of the fourth direction and the fifth direction. Figure 36 It should be understood that these directional terms are only used to facilitate the description of this application and simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting this application.

[0068] 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.

[0069] The main unit module 10 includes a power supply assembly 13, a main unit bracket 12, an air compressor 11 and a main unit housing 16. The power supply assembly 13, the air compressor 11 and the main unit bracket 12 can all be detachably arranged in the main unit housing 16. The power supply assembly 13 and the air compressor 11 are electrically connected. The power supply assembly 13 and the air compressor 11 are both arranged on the main unit bracket 12, and the air compressor 11 is snap-fitted to the main unit bracket 12.

[0070] The atomizer module 20 includes an atomizing shell 22 and a nozzle 23 arranged on the atomizing shell 22. The atomizing shell 22 has an air channel 22b and a liquid storage chamber 22a. At least a portion of the air channel 22b is formed by injection molding. The liquid storage chamber 22a is used to store the atomizing medium to be atomized. The atomizing shell 22 is detachably connected to the main body housing 16.

[0071] The air compressor 11 is connected to one end of the air channel 22b, and the nozzle 23 is connected to the other end of the air channel 22b and the liquid storage chamber 22a respectively, so that the air flow from the air compressor 11 atomizes the atomized liquid in the liquid storage chamber 22a to generate an aerosol.

[0072] 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 atomized liquid stored in the atomizer module 20 is a drug solution, such as minoxidil. In another example, the electronic atomization device is an electronic cigarette, and the atomized liquid stored in the atomizer module 20 is tobacco oil.

[0073] The air compressor 11 in the embodiment of the present application refers to a device capable of compressing gas, such as an air pump.

[0074] The air compressor 11 is electrically connected to the power supply assembly 13, which drives the air compressor 11 to provide a high-speed airflow to the nozzle 23. The atomizer module 20 is an atomizing component in the electronic atomizing device that can atomize the atomizing liquid to generate an aerosol.

[0075] The atomizing housing 22 can store atomized liquid. The atomized liquid in the liquid storage chamber 22a is transmitted to the nozzle 23 and atomized under the action of the high-speed airflow provided by the air compressor 11, so that the atomized liquid is atomized to generate an aerosol.

[0076] In fact, the nozzle 23 also has a mist outlet 23 a , and the aerosol generated by the atomization of the atomized liquid can reach the outside of the atomizer module 20 through the mist outlet 23 a of the nozzle 23 .

[0077] The power supply assembly 13, the air compressor 11 and the main frame bracket 12 are all detachably arranged in the main frame housing 16. At the same time, the air compressor 11 is snap-connected to the main frame bracket 12. Therefore, on the one hand, it is convenient to disassemble and assemble the power supply assembly 13, the air compressor 11 and the main frame bracket 12. On the other hand, the snap-connection can also improve the installation stability of the air compressor 11.

[0078] It should be noted that the power supply assembly 13 is also disposed on the main frame bracket 12 , but the specific installation method of the power supply assembly 13 can be set according to actual conditions. For example, the power supply assembly 13 is snap-fitted to the main frame bracket 12 .

[0079] Of course, the power supply assembly 13 may also be installed in other ways, such as plugging, bonding, fastening, etc.

[0080] The atomizer housing 22 is detachably connected to the main unit housing 16, that is, the main unit module 10 and the atomizer module 20 are detachable from each other. Thus, on the one hand, by detaching the atomizer module 20 from the main unit module 10, it is possible to easily inject liquid into the atomizer module 20 through the liquid injection device. On the other hand, the main unit module 10 can be assembled into a whole first, then the atomizer module 20 can be assembled into a whole, and finally the atomizer module 20 and the main unit module 10 can be assembled together, which can greatly improve the installation convenience of the electronic atomization device.

[0081] The air passage 22b in the atomizer module 20 may be partially or entirely injection-molded from the atomizer housing 22. This reduces the use of flexible pipes, which improves installation convenience and reduces the potential for poor sealing when flexible pipes are used as the structure of the air passage 22b.

[0082] The electronic atomization device provided in the embodiment of the present application includes a host module 10 and an atomizer module 20. The power supply assembly 13, the air compressor 11 and the host bracket 12 are all detachably arranged in the host housing 16, the power supply assembly 13 and the air compressor 11 are electrically connected, and the power supply assembly 13 and the air compressor 11 are both arranged on the host bracket 12. Thus, the detachable installation method is adopted, which can facilitate the disassembly and assembly of the power supply assembly 13, the air compressor 11 and the host bracket 12. At the same time, the air compressor 11 is clamped with the host bracket 12, and the air compressor 11 can be clamped on the host bracket 12, which can improve the stability of the installation of the air compressor 11. The atomizer housing 22 is formed by injection molding at least a portion of the air channel 22b and the liquid storage chamber 22a, thereby making it possible to directly mold at least a portion of the air channel 22b in the atomizer housing 22, and to avoid using a hose as the air channel 22b structure as much as possible, thereby reducing the difficulty of assembly and making the atomizer module 20 more convenient to assemble. At the same time, the atomizer housing 22 is detachably connected to the main unit housing 16, which facilitates the disassembly and assembly between the atomizer module 20 and the main unit module 10, and further facilitates the repair and replacement of the atomizer module 20 or the main unit module 10. As can be seen, the electronic atomizer device of the embodiment of the present application is easy to assemble, which greatly improves the convenience of the electronic atomizer device during use.

[0083] In one embodiment, please refer to Figures 2 to 4 The mainframe bracket 12 has a mounting cavity 12a. The power supply assembly 13 and the air compressor 11 are both disposed within the mounting cavity 12a, spaced apart from each other. The air compressor 11 has an air outlet 11a at one end along a first direction, and the power supply assembly 13 is disposed at the other end of the air compressor 11 along the first direction. At least a portion of one side of the mainframe bracket 12 along a second direction is open to form an installation inlet 12b communicating with the mounting cavity 12a. The second direction is perpendicular to the first direction. Thus, the air compressor 11 and the power supply assembly 13 can be installed into the mounting cavity 12a through the installation inlet 12b, facilitating assembly and disassembly of the air compressor 11 and the power supply assembly 13.

[0084] Specifically, the power supply assembly 13 and the air compressor 11 are both arranged in the installation cavity 12a, and the main frame bracket 12 can fix the power supply assembly 13 and the air compressor 11. In addition, the power supply assembly 13 and the air compressor 11 are spaced apart from each other to prevent the two from colliding due to looseness, thereby causing damage to the structure. It can be seen that, on the one hand, by providing the main frame bracket 12, the air compressor 11 can be clamped in the installation cavity 12a to improve the stability of the installation of the air compressor 11. Therefore, during the use of the electronic atomization device, the air compressor 11 can be made less likely to loosen, so that the air compressor 11 is firmly installed, and the purpose of stable air supply to the nozzle 23 can be achieved. On the other hand, the installation method of using a spacing arrangement between the power supply assembly 13 and the air compressor 11 can prevent the power supply assembly 13 and the air compressor 11 from colliding with each other, thereby avoiding damage to the power supply assembly 13 and the air compressor 11.

[0085] Specifically, the power supply assembly 13 is disposed at one end of the air compressor 11 away from the air outlet 11 a , and is spaced apart from the air compressor 11 along the first direction.

[0086] The installation inlet 12b is located at one side of the installation cavity 12a along the second direction, and the installation inlet 12b is communicated with the installation cavity 12a.

[0087] It should be noted that a portion of one side of the main frame bracket 12 along the second direction may be open to form the installation entrance 12b. Depending on the actual situation, the entire area of ​​one side of the main frame bracket 12 along the second direction may be open to form the installation entrance 12b.

[0088] In one embodiment, please refer to Figures 2 to 4 On opposite sides of the installation entrance 12b, portions of the mainframe bracket 12's wall protrude to form spaced-apart bracket clips 121. The air compressor 11 is inserted into the installation cavity 12a through the gap between the two bracket clips 121. The bracket clips 121 abut against the outer surface of the air compressor 11 to secure the air compressor 11 within the installation cavity 12a. This allows the air compressor 11 to be more securely installed within the installation cavity 12a. The bracket clips 121 also facilitate assembly and disassembly of the air compressor 11.

[0089] Specifically, a bracket buckle 121 is formed on the walls on opposite sides of the installation entrance 12b. The two bracket buckles 121 are spaced apart from each other to facilitate the air compressor 11 to pass through the installation entrance 12b from the gap and then be installed in the installation cavity 12a.

[0090] When the air compressor 11 is installed in the installation cavity 12a, the bracket clip 121 fits against the outer surface of the air compressor 11, so as to restrict the air compressor 11 from escaping from the installation cavity 12a from the installation entrance 12b by abutting against the air compressor 11, thereby achieving the purpose of clamping the air compressor 11 in the installation cavity 12a.

[0091] It should be noted that the specific shape of the bracket buckle 121 is not limited.

[0092] For example, see Figure 5 Along the protruding direction of the bracket clips 121, the two bracket clips 121 bend toward each other, and the bracket clips 121 elastically deform toward each other, allowing the air compressor 11 to be inserted into the installation cavity 12a. This can improve the contact effect of the bracket clips 121 on the air compressor 11, thereby improving the installation stability of the air compressor 11 in the installation cavity 12a.

[0093] Specifically, the protruding direction of the bracket buckle 121 refers to a direction in which the bracket buckle 121 protrudes through other areas of the wall relative to the host bracket 12 to extend away from the installation cavity 12 a.

[0094] In fact, the two bracket clips 121 are bent toward each other from the side closer to the mounting cavity 12a to the side farther away from the mounting cavity 12a. Therefore, after the air compressor 11 is inserted into the mounting cavity 12a, the bracket clips 121 can better fit and abut against the outer surface of the air compressor 11, thereby retaining the air compressor 11 in the mounting cavity 12a.

[0095] It should be noted that the bracket buckle 121 is a buckle structure with a certain elastic deformation capability.

[0096] Therefore, when the air compressor 11 is installed into the installation cavity 12a from the outside through the installation entrance 12b, the air compressor 11 pushes the two bracket clips 121 from the outside, causing the two bracket clips 121 to elastically deform and shift away from each other, thereby increasing the distance between the two bracket clips 121, making it easier for the air compressor 11 to be inserted into the installation cavity 12a.

[0097] The same thing is that when the air compressor 11 is removed from the installation cavity 12a through the installation entrance 12b, the air compressor 11 pushes the two bracket clips 121 from the inside, causing the two bracket clips 121 to elastically deform and shift away from each other, thereby increasing the distance between the two bracket clips 121, making it easier for the air compressor 11 to be inserted into the installation cavity 12a.

[0098] It should be noted that the specific shape of the bracket buckle 121 can be set according to actual conditions.

[0099] For example, the bracket buckle 121 is a curved plate.

[0100] For example, see Figure 5 and Figure 6 The two bracket buckles 121 have abutment surfaces 121a on the sides close to each other, and the abutment surfaces 121a are curved surfaces 271a that correspond to and fit the outer peripheral surface of the air compressor 11. This can improve the effect of the bracket buckles 121 in preventing the air compressor 11 from falling out of the installation cavity 12a, and can further improve the installation stability of the air compressor 11.

[0101] Specifically, after the air compressor 11 is inserted into the installation cavity 12a, the abutting surface 121a is used to abut against the outer peripheral surface of the air compressor 11. By setting the abutting surface 121a as a curved surface 271a, the abutting surface 121a can be easily fitted to the outer surface of the air compressor 11.

[0102] It should be noted that the outer surface of the air compressor 11 can also be a curved surface 271a, and the degree of curvature of the outer surface of the air compressor 11 and the abutment surface 121a can be the same. In this way, the abutment surface 121a and the air compressor 11 can fit more closely, making the installation stability of the air compressor 11 higher.

[0103] For example, see Figure 6 The two bracket clips 121 each have an abutment surface 121a and a guide surface 121b on the side closest to each other. The guide surface 121b is located on the side of the abutment surface 121a facing away from the installation cavity 12a. The abutment surface 121a is a curved surface 271a that corresponds to and fits against the outer circumference of the air compressor 11. Along the protruding direction of the bracket clips 121, the guide surface 121b is an inclined surface that tilts away from each other. This facilitates the installation of the air compressor 11 into the installation cavity 12a.

[0104] Specifically, the guide surfaces 121b are inclined surfaces and are inclined in a direction away from each other along the protruding direction of the bracket clip 121, that is, from the side closest to the mounting cavity 12a to the side further away from the mounting cavity 12a. In other words, the distance between the two guide surfaces 121b gradually decreases from the side further away from the mounting cavity 12a to the side closer to the mounting cavity 12a. As a result, when the air compressor 11 is inserted into the mounting cavity 12a through the installation entrance 12b, when the air compressor 11 first contacts the two guide surfaces 121b, the relatively large distance between the two guide surfaces 121b allows the air compressor 11 to easily fit between the two guide surfaces 121b. As the air compressor 11 gradually moves toward the mounting cavity 12a, the distance between the two guide surfaces 121b gradually decreases. Under the action of the air compressor 11, the two guide surfaces 121b can guide the two bracket clips 121 to elastically deform in a direction away from each other, thereby guiding the air compressor 11 into the mounting cavity 12a.

[0105] In one embodiment, please refer to Figure 4 and Figure 5 Part of the cavity wall of the mounting cavity 12a protrudes into the mounting cavity 12a to form a stopper 122. The stopper 122 abuts against the power supply assembly 13 and the air compressor 11, respectively, to separate the power supply assembly 13 from the air compressor 11. This further reduces the risk of collision between the power supply assembly 13 and the air compressor 11, thereby improving the safety of the structure.

[0106] Specifically, the stopper 122 is a protruding structure formed by protruding from the wall of the mounting cavity 12a. By abutting the air compressor 11, it can limit the air compressor 11 from rocking toward the side closer to the power supply assembly 13. At the same time, by abutting the power supply assembly 13, the stopper 122 can also limit the power supply assembly 13 from rocking toward the side closer to the air compressor 11, thereby improving the stability of the air compressor 11 and the power supply assembly 13 and reducing the risk of collision between the two due to rocking.

[0107] It should be noted that the specific shape of the limiting portion 122 is not limited.

[0108] For example, the limiting portion 122 is a convex plate, one side of the convex plate abuts against the end surface of the air compressor 11 close to the power supply assembly 13, and the other side of the convex plate abuts against the end surface of the power supply assembly 13 close to the air compressor 11.

[0109] For example, the retaining portion 122 includes a first, second, and third raised plate spaced apart along a first direction. One end of the air compressor 11 abuts against the end of the mainframe bracket 12, while the other end of the air compressor 11 abuts against the first raised plate. The power supply assembly 13 is positioned in the space between the second and third raised plates, with its opposite ends abutting against the second and third raised plates, respectively. This significantly improves the installation stability of the power supply assembly 13 and the air compressor 11.

[0110] In one embodiment, please refer to Figure 5 and Figure 7 The mainframe module 10 includes a circuit board 14. The mainframe bracket 12 includes a mounting end wall 123 located on the side of the power supply assembly 13 facing away from the air compressor 11. The mounting end wall 123 has a mounting end surface 123a facing away from the mounting cavity 12a. A portion of the mounting end surface 123a protrudes to form a third clamping member 1231. The circuit board 14 is mounted on the mounting end surface 123a and is clamped to the third clamping member 1231. This greatly improves the installation stability of the circuit board 14.

[0111] Specifically, the circuit board 14 is also mounted on the host bracket 12 , and by being engaged with the third engaging member 1231 , the installation stability of the circuit board 14 can be greatly improved.

[0112] Furthermore, the circuit board 14 is not mounted within the mounting cavity 12a of the mainframe bracket 12, but rather on the outer end surface of the mainframe bracket 12. That is, the circuit board 14 is mounted outside the mounting cavity 12a. This allows the power supply assembly 13 and the circuit board 14 to be separated by the mounting end wall 123 at the end of the mainframe bracket 12. This prevents damage to components on the circuit board 14 due to accidental contact between the power supply assembly 13 and the circuit board 14, thereby preventing short circuits in the circuit board 14, fires, or other mainframe malfunctions.

[0113] At the same time, mounting the circuit board 14 on the mounting end surface 123 a can facilitate assembly and disassembly of the circuit board 14 , thereby facilitating subsequent maintenance and replacement.

[0114] The third clamping member 1231 is a protruding structure formed by protruding from the installation end surface 123a, and its specific shape is not limited.

[0115] For example, see Figure 7 and Figure 8 The third clamping member 1231 includes a fixing post 1232, which is disposed on the mounting end surface 123a. The circuit board 14 has a fixing hole, and the fixing post 1232 is passed through the fixing hole to clamp the circuit board 14 on the mounting end surface 123a. This improves the installation stability of the circuit board 14.

[0116] Specifically, when the circuit board 14 is mounted on the mounting end surface 123 a , the fixing posts 1232 penetrate into the fixing holes to limit the movement of the circuit board 14 , thereby improving the stability of the circuit board 14 .

[0117] The fixing columns 1232 and the fixing holes may correspond one to one. Depending on the actual situation, the number of fixing holes may be greater than the number of fixing columns 1232 , or the number of fixing columns 1232 may be greater than the number of fixing holes.

[0118] The number of fixing posts 1232 and fixing holes is not limited. For example, the third clamping member 1231 includes a plurality of fixing posts 1232, and the circuit board 14 has a plurality of fixing holes, and the fixing posts 1232 are disposed in the fixing holes in a one-to-one correspondence.

[0119] For example, see Figure 7 and Figure 8 The third clamping member 1231 further includes a clamping plate 1233 disposed on the mounting end surface 123a. A portion of the clamping plate 1233 protrudes from the side of the circuit board 14 near the circuit board 14 to form a first abutting portion 1234. When the circuit board 14 is mounted on the fixing post 1232 through the fixing hole, the first abutting portion 1234 abuts against the side of the circuit board 14 facing away from the mounting end surface 123a. This further improves the mounting stability of the circuit board 14.

[0120] Specifically, when the circuit board 14 is installed on the mounting end surface 123a, the fixing column 1232 is inserted into the fixing hole, and the first abutting portion 1234 of the clamping plate 1233 abuts against the side surface of the circuit board 14 away from the mounting end surface 123a, thereby further limiting the movement of the circuit board 14 toward the side away from the mounting end surface 123a, and limiting the circuit board 14 from falling off the fixing column 1232, thereby further improving the installation stability of the circuit board 14.

[0121] In one embodiment, please refer to Figure 2 and Figure 4 The main module 10 further includes a foam pad 15. At least a portion of the foam pad 15 is located between the power assembly 13 and the air compressor 11. The foam pad 15 is bonded to the end of the power assembly 13 that is closest to the air compressor 11. This cushions the relative motion between the power assembly 13 and the air compressor 11, reducing the risk of collision between the two.

[0122] Specifically, only a portion of the foam 15 may be located between the power assembly 13 and the air compressor 11, or the entire foam 15 may be located between the power assembly 13 and the air compressor 11. By providing the foam 15 between the power assembly 13 and the air compressor 11, the foam 15 can buffer the relative movement between the power assembly 13 and the air compressor 11, thereby separating the power assembly 13 and the air compressor 11 and preventing collision between the power assembly 13 and the air compressor 11.

[0123] At the same time, sticking the foam 15 to the power supply assembly 13 can prevent the foam 15 from loosening and shifting.

[0124] The specific type of foam 15 can be set according to actual conditions. For example, the foam 15 is single-sided adhesive (ethylene-vinyl acetate copolymer). It is only adhesive on the side that is attached to the power assembly 13, while the side close to the air compressor 11 is non-adhesive. This can prevent the foam 15 from sticking to the air compressor 11 at the same time, thereby preventing the power assembly 13 from causing the air compressor 11 to shake.

[0125] In one embodiment, please refer to Figure 9 The air channel 22b includes a first air channel 22ba, a second air channel 22bb and a third air channel 22bc. One end of the first air channel 22ba has a first ejection hole, and the other end of the first air channel 22ba is connected to the second air channel 22bb. The first ejection hole is connected to the air compressor 11. One end of the third air channel 22bc has a second ejection hole, and the other end of the third air channel 22bc is connected to the second air channel 22bb. The second ejection hole is connected to the nozzle 23, and the first air channel 22ba and the third air channel 22bc are respectively arranged vertically relative to the second air channel 22bb.

[0126] Thus, on the one hand, the first air channel 22ba is connected to the air compressor 11, and the third air channel 22bc is connected to the nozzle 23. The first air channel 22ba and the third air channel 22bc are respectively connected vertically relative to the second air channel 22bb, and the extension direction of the air channel 22b can be changed without using a hose. This makes it easier for the air channel 22b to avoid other structures in the atomizing housing 22, such as the liquid storage chamber 22a. Therefore, the space in the atomizing housing 22 can be reasonably utilized, the space utilization rate inside the electronic atomizing device can be improved, and the structure of the electronic atomizing device can be more compact. On the other hand, the first air channel 22ba and the third air channel 22bc are respectively connected vertically with the second air channel 22bb, which facilitates the smooth demoulding of the mold forming the air channel 22b. It is also beneficial to reduce the generation of burrs when the air channel 22b collides with the mold opening, thereby making the air flow smoother.

[0127] Specifically, the air passage 22 b is a passage for high-speed air flow. The high-speed air flow from the air compressor 11 enters the nozzle 23 through the first air passage 22 ba , the second air passage 22 bb , and the third air passage 22 bc .

[0128] The formation method of the first air channel 22ba, the second air channel 22bb, and the third air channel 22bc is not limited.

[0129] For example, the first air channel 22ba and the second air channel 22bb are formed by a collision-through method, thereby reducing the risk of a burst front and making the air flow smoother.

[0130] Specifically, during the molding process of the atomizing housing 22, after the mold for molding the atomizing housing 22 is closed, the mold for molding the first air channel 22ba and the mold for molding the second air channel 22bb are connected by a penetration method, so that the first air channel 22ba and the second air channel 22bb are formed after the mold is opened. It should be noted that the use of the penetration mold opening method can improve the stability of mold production, and the penetration position is not easily formed. Therefore, the formation of the penetration front will not block the air channel 22b, thereby not affecting the flow of gas.

[0131] For example, the second air channel 22bb and the third air channel 22bc are formed by a collision-through method, thereby reducing the risk of burst fronts and making the air flow smoother.

[0132] Specifically, during the molding process of the atomizing shell 22, after the mold for molding the atomizing shell 22 is closed, the mold for molding the second air channel 22bb and the mold for molding the third air channel 22bc are penetrated at the connection point to form the second air channel 22bb and the third air channel 22bc after the mold is opened. This can also prevent the air channel 22b from being blocked due to the formation of a batch front, making the air flow smoother.

[0133] The first air channel 22ba has a first ejection hole. This first ejection hole serves as an exit for the mold forming the first air channel 22ba after the air channel 22b is formed. Furthermore, after the atomizer module 20 and the main unit module 10 are assembled, the first ejection hole is used to communicate with the air compressor 11. Thus, the first ejection hole also serves as the entrance for airflow into the air channel 22b.

[0134] The second air channel 22bb is a connecting channel between the first air channel 22ba and the third air channel 22bc, so as to allow the air flow from the first die-out hole to flow to the third air channel 22bc.

[0135] It should be noted that one end of the second air channel 22bb has a third ejection hole, which is an exit for the mold forming the second air channel 22bb to be ejected after the air channel 22b is formed.

[0136] The third air channel 22bc has a second ejection hole. This second ejection hole serves as an exit for the mold forming the third air channel 22bc after the air channel 22b is formed. Furthermore, after the atomizer module 20 and the main unit module 10 are assembled, the second ejection hole is connected to the nozzle 23, allowing airflow to enter the nozzle 23 and atomize the atomized liquid flowing into the nozzle 23.

[0137] The shapes and sizes of the first air passage 22 ba , the second air passage 22 bb , and the third air passage 22 bc are not limited, as long as they allow the high-speed airflow generated by the air compressor 11 to pass through and enter the nozzle 23 .

[0138] For example, the cross-sectional shape of the first air channel 22 ba may be circular or square, which facilitates the processing and forming of the first air channel 22 ba.

[0139] For example, see Figure 11 The cross-section of the second air channel 22bb is square. This facilitates the molds of the first air channel 22ba and the third air channel 22bc to penetrate the mold of the second air channel 22bb, thereby improving mold production stability. A front is less likely to form at the penetration point, thus preventing the formation of a front and thereby blocking the air channel 22b, thereby preventing the flow of gas from being affected.

[0140] For another example, the cross-sectional area of ​​at least one of the first air channel 22ba and the second air channel 22bb is greater than or equal to 3 mm. 2 That is, the cross-sectional area of ​​only the first air passage 22ba may be greater than or equal to 3 mm. 2 Alternatively, only the cross-sectional area of ​​the second air passage 22bb may be greater than or equal to 3 mm 2 Alternatively, the cross-sectional areas of the first air channel 22ba and the second air channel 22bb are both greater than or equal to 3 mm. 2In this way, the resistance of the air flow can be reduced, ensuring that sufficient air flow enters the nozzle 23.

[0141] The first air channel 22ba is vertically connected to the second air channel 22bb, and the second air channel 22bb is vertically connected to the third air channel 22bc. In other words, the extension direction of the first air channel 22ba is perpendicular to the extension direction of the second air channel 22bb, and the extension direction of the second air channel 22bb is also perpendicular to the extension direction of the third air channel 22bc. As a result, the extension direction of the air channel 22b can be bent and turned within the atomizing housing 22, so as to facilitate the structural layout within the atomizing housing 22.

[0142] In one embodiment, referring to the figure, the atomizing housing 22 includes an airway wall forming the second airway 22bb, the airway wall including a first airway wall surface, the first airway wall surface having a first through hole, the first airway 22ba communicating with the second airway 22bb via the first through hole, and the first airway wall surface being a plane. Thus, by setting the contact surface of the mold for the second airway 22bb and the mold for the first airway 22ba to a plane, it is possible to facilitate the mold for forming the first airway 22ba and the mold for forming the second airway 22bb to penetrate each other, thereby improving mold production stability and preventing the formation of a flash at the penetration position, thereby making airflow smoother.

[0143] Specifically, the first air passage 22ba and the second air passage 22bb are communicated with each other through the first through hole.

[0144] It is understood that the shapes of the two walls of the second air channel 22bb adjacent to the first air channel wall are not limited, for example, they can be flat or curved.

[0145] The cross-sectional shape of the second air channel 22bb is not limited. For example, the cross-sectional shape of the second air channel 22bb can be square or trapezoidal.

[0146] In other embodiments, only the area where the first through hole is located may be a plane.

[0147] In one embodiment, the atomizing housing 22 includes an airway wall forming the second airway 22bb, the airway wall including a second airway wall surface having a second through hole, the third airway 22bc communicating with the second airway 22bb via the second through hole, and the second airway wall surface being a plane. Thus, by setting the surface connecting the mold for the second airway 22bb and the mold for the third airway 22bc to be a plane, the molds for forming the second airway 22bb and the molds for forming the third airway 22bc can be easily opened by contact, thereby improving mold production stability and preventing flash from forming at the contact point, thereby promoting smoother airflow.

[0148] Specifically, the second air passage 22bb and the third air passage 22bc are communicated with each other through the second through hole.

[0149] It is understood that, in the second air channel 22bb, the shapes of the two walls adjacent to the second air channel wall are not limited, for example, they can be flat or curved.

[0150] In one embodiment, please refer to Figure 9 One end of the second air channel 22bb has a third mold opening. The atomizer module 20 also includes a second sealant 24, which is positioned at the third mold opening to seal it. Thus, after the mold for the second air channel 22bb is removed through the third mold opening, the second sealant 24 seals the third mold opening, ensuring the overall tightness of the air channel 22b and, in turn, maintaining the stability of the air pressure within the electronic atomizer device.

[0151] Specifically, the third die-out hole is an outlet for the mold forming the second air channel 22bb to be ejected after the air channel 22b is formed. The third die-out hole is located at the end of the second air channel 22bb, which can facilitate the ejection of the mold.

[0152] The second sealing member 24 can be used in any manner to seal the third die-outlet hole, as long as it prevents gas leakage from the third die-outlet hole. For example, the second sealing member 24 can be a threaded plug, mechanically sealing the third die-outlet hole. In another example, the second sealing member 24 can be a silicone sealant for sealing the air passage 22b, sealing the third die-outlet hole with a sealant.

[0153] In one embodiment, please refer to Figure 9 The nozzle 23 and the second air channel 22bb are respectively located on opposite sides of the liquid storage chamber 22a along the first direction.

[0154] Along the first direction, the first air channel 22ba is located on a side of the second air channel 22bb away from the liquid storage chamber 22a, and the third air channel 22bc is located on a side of the second air channel 22bb close to the liquid storage chamber 22a.

[0155] The second air channel 22bb extends along the third direction, such that the third air channel 22bc avoids the connection between the liquid storage chamber 22a and the nozzle 23 and communicates with the nozzle 23. The first direction is perpendicular to the third direction. Thus, by extending the second air channel 22bb along the third direction, the first air channel 22ba and the third air channel 22bc are respectively connected perpendicularly to the second air channel 22bb. This allows the air channel 22b within the electronic atomization device to avoid the liquid storage chamber 22a, thereby fully utilizing the internal space of the atomization housing 22 and making the electronic atomization device more compact.

[0156] Specifically, the first air channel 22ba is located on the side of the second air channel 22bb close to the air compressor 11, and the first air channel 22ba is connected to the end of the second air channel 22bb. The third air channel 22bc is located on the side of the second air channel 22bb away from the air compressor 11, and the third air channel 22bc is connected to the other end of the second air channel 22bb.

[0157] The second air channel 22bb extends along the third direction, which facilitates smooth demoulding of the mold for forming the second air channel 22bb after the air channel 22b is formed.

[0158] The first direction and the third direction are perpendicular to each other. For example, the first direction is the vertical direction of the electronic atomization device, and the third direction is the horizontal direction of the electronic atomization device.

[0159] In one embodiment, please refer to Figure 9 The air channel 22b also has a fourth air channel 22bd, one end of which is connected to the second ejection hole, and the other end of the fourth air channel 22bd is connected to the nozzle 23. From the end close to the second ejection hole to the end close to the nozzle 23, the fourth air channel 22bd is connected to the nozzle 23 by bending. By designing the fourth air channel 22bd to bend, on the one hand, it can adapt to a compact space layout, making the electronic atomization device more compact. On the other hand, by bending, it is convenient for the high-speed airflow flowing from the air channel 22b to the nozzle 23 to fully interact with the atomized liquid, which can improve the atomization effect of the nozzle 23.

[0160] Specifically, the fourth air channel 22bd may be formed in any manner. For example, the second die-out hole and the nozzle 23 are connected via a connecting pipe, and the channel of the connecting pipe is the fourth channel.

[0161] It is understandable that the material type of the connecting tube is not limited, as long as it can be bent and connected to the second die-out hole and the nozzle 23. For example, the connecting tube is a plastic tube or a silicone tube.

[0162] It is understood that the connecting tube is connected to the second mold hole and the nozzle 23, respectively, to achieve communication with the air passage 22b of the electronic atomization device. The connection method of the connecting tube to the second mold hole and the nozzle 23 is not limited. For example, the connecting tube is connected to the second mold hole and the nozzle 23, respectively, through a connecting joint. In another example, the connecting tube is connected to the second mold hole and the nozzle 23, respectively, by an interference fit.

[0163] In one embodiment, please refer to Figure 9 and Figure 10The atomizing housing 22 includes an adapter 222 and an atomizing cartridge 221. The adapter 222 has a first air channel 22ba, a second air channel 22bb, and a third air channel 22bc. The atomizing cartridge 221 has a fifth air channel 22be. The second ejection hole is connected to the nozzle 23 through the fifth air channel 22be. The adapter 222 and the atomizing cartridge 221 enclose a liquid storage chamber 22a. Thus, by connecting the fifth air channel 22be of the atomizing cartridge 221 with the second ejection hole and the nozzle 23, respectively, the air channel 22b of the electronic atomizing device can be kept stable, thereby ensuring the consistency of the gas flow in the air channel 22b and improving the atomization efficiency of the atomized liquid.

[0164] It should be noted that the fifth air passage 22be may be directly connected to the nozzle 23, or the fourth air passage 22bd may be formed through the atomizing housing 22 to be indirectly connected to the nozzle 23 through the fourth air passage 22bd.

[0165] The cross-sectional areas of the air passages 22b may be the same or different. For example, the cross-sectional area of ​​the fifth air passage 22be is larger than the cross-sectional areas of the fourth air passage 22bd and the third air passage 22bc. This facilitates communication between the air passages 22b and improves the airflow efficiency of the air passages 22b.

[0166] In one embodiment, the atomizer module 20 further includes a sealing rubber ring, which is provided at the connection between the adapter 222 and the atomizer cartridge 221. When the adapter 222 and the atomizer cartridge 221 are combined to form the liquid storage chamber 22a, the sealing rubber ring is used to seal the liquid storage chamber 22a to prevent leakage of the atomized liquid.

[0167] In one embodiment, please refer to Figure 9 and Figure 10 The atomizer module 20 includes a third seal 25, which is provided at the connection between the first mold opening and the air compressor 11. Thus, the third seal 25 seals the connection between the first air passage 22ba and the air compressor 11, thereby ensuring the overall sealing of the air passage 22b and thus ensuring the stability of the air pressure in the electronic atomizer device.

[0168] In one embodiment, please refer to Figure 9 and Figure 10 The atomizer module 20 includes a third seal 25, which is provided at the connection between the second mold opening and the fifth air channel 22be. Thus, the third seal 25 seals the connection between the third air channel 22bc and the fifth air channel 22be, thereby ensuring the sealing of the entire air channel 22b, thereby ensuring the stability of the air pressure of the electronic atomizer device.

[0169] In one embodiment, please refer to Figure 10One end of the second air channel 22bb has a third mold opening, and the atomizer module 20 further includes a second sealing member 24 disposed at the third mold opening. At least one of the second sealing member 24 and the third sealing member 25 is made of a soft rubber material.

[0170] Specifically, only the second sealant 24, only the third sealant 25, or both the second and third sealants 24, 25 can be made of a soft rubber material. The soft rubber material can be appropriately deformed to accommodate different design and dimensional requirements. Thus, the second and third sealants 24, 25 can effectively seal the airway 22b, thereby improving the sealing performance of the electronic atomization device and, in turn, the atomization efficiency.

[0171] Among them, soft rubber materials are not limited, such as sealing silicone.

[0172] In one embodiment, one end of the second air channel 22bb has a third die-out hole, and the atomizer module 20 further includes a second seal 24 disposed at the third die-out hole, and the hardness of at least one of the second seal 24 and the third seal 25 is greater than or equal to 40 Shore A and less than or equal to 80 Shore A. For example, the hardness of at least one of the second seal 24 and the third seal 25 is 40 Shore A, 60 Shore A, or 80 Shore A. Thus, by adopting a hardness within the above range, the second seal 24 and the third seal 25 can have good elasticity and structural strength, and can effectively fill and seal the small gap between the air channels 22b and the air channels 22b, thereby improving the sealing effect.

[0173] Specifically, the hardness of only the second seal 24 may be greater than or equal to 40 Shore A and less than or equal to 80 Shore A, or the hardness of only the third seal 25 may be greater than or equal to 40 Shore A and less than or equal to 80 Shore A, or the hardness of both the second seal 24 and the third seal 25 may be greater than or equal to 40 Shore A and less than or equal to 80 Shore A.

[0174] In one embodiment, please refer to Figure 10 and Figure 11 The atomizer module 20 also includes an atomizer cover 223, a comb assembly 224, and a nozzle 23 seal. The liquid storage chamber 22a has a liquid outlet. The atomizer cover 223 is arranged at the end of the adapter 222 away from the liquid storage chamber 22a. The comb assembly 224 is arranged on one side of the nozzle 23 mist outlet 23a. The nozzle 23 is connected to the liquid outlet of the liquid storage chamber 22a. The nozzle 23 seal is arranged at the connection between the nozzle 23 and the liquid outlet to prevent the atomized liquid from leaking from the liquid outlet. In this way, the electronic atomization device can achieve a better atomization effect.

[0175] In one embodiment, please refer to Figure 1and Figure 13 The host module 10 includes an indicator light 17 and a control component 18. The host housing 16 has a accommodating cavity 16a and a button port 16b. The accommodating cavity 16a is connected to the outside world through the button port 16b. The indicator light 17 is arranged in the accommodating cavity 16a. The control component 18 includes a pressing member 181 and a control switch 182. The control switch 182 is arranged in the accommodating cavity 16a and is electrically connected to the indicator light 17 and the power supply component 13 respectively. The pressing member 181 is arranged at the button port 16b to cooperate with the control switch 182 to control the opening and closing of the indicator light 17 and the power supply component 13.

[0176] The end surface of the pressing member 181 facing away from the accommodating cavity 16a has a light-shielding area and a light-displaying area extending circumferentially around the light-shielding area. The light-displaying area is made of a light-transmitting material to allow at least part of the light of the indicator light 17 to pass through the light-displaying area.

[0177] Specifically, the position of the key opening 16b is not limited. For example, a portion of the side wall of the host housing 16 is opened to form the key opening 16b. For another example, a portion of the end surface of the host housing 16 is opened to form the key opening 16b.

[0178] The shape of the button opening 16b is not limited. For example, the button opening 16b is circular or square.

[0179] The number and position of the indicator lights 17 are not limited, as long as the light emitted by the indicator lights 17 can be transmitted through the light display area. For example, one indicator light 17 is located at the bottom of the light display area. For another example, multiple indicator lights 17 are located at the bottom of the light display area.

[0180] It is understandable that the control switch 182 can be electrically connected to the indicator light 17 and the power supply assembly 13 through a line, or they can all be located on the circuit board 14 and electrically connected to the circuit board 14.

[0181] For example, the host module 10 further includes a circuit board 14, and the control switch 182 and the indicator light 17 are both located on the circuit board 14 and electrically connected to the circuit board 14. Thus, by integrating the control switch 182 and the indicator light 17 on the circuit board 14, it is possible to save internal space of the electronic atomization device and facilitate the structural layout within the electronic atomization device.

[0182] The pressing member 181 is a mechanical button structure for the user to press to turn on or off the electronic atomization device. By pressing the pressing member 181, the user can make the pressing member 181 cooperate with the control switch 182 to control the on and off of the indicator light 17.

[0183] The control switch 182 controls the on and off of the indicator light 17 by closing and opening the control circuit.

[0184] The structure type of the control switch 182 is not limited, as long as it can control the closing and opening of the circuit.

[0185] For example, the control switch 182 includes a spring element and a switch body, with the spring element disposed within the switch body. When a user presses the pressing member 181, the pressing member 181 contacts the spring element, thereby turning the indicator light 17 and the power supply assembly 13 on and off. The spring element's elastic deformation creates a "clicking" sensation, enhancing the user's sense of control.

[0186] The method of forming the shading area is not limited. Part of the pressing member 181 can be made of opaque material to form the shading area, or the shading member 1815 can be used to block part of the pressing member 181 to form the shading area.

[0187] The shape of the light shielding area is not limited, as long as it can block the light of the indicator light 17. For example, the light shielding area is circular or square.

[0188] The material type of the light display area is not limited, as long as it can make the light of the indicator light 17 pass through. For example, the material of the light display area is silicone, or the material of the light display area is PC material.

[0189] It should be noted that the light-transmitting material refers to a material that can allow part of the light or all of the light of the indicator light 17 to pass through. It can be a fully transparent material or a translucent material.

[0190] The light display area is arranged around the circumference of the light shielding area.

[0191] It should be noted that the specific shape of the light display area can be set according to actual conditions.

[0192] For example, the light display area is ring-shaped, the inner contour of the ring is close to the outer contour of the light-shielding area, and the outer contour of the ring is close to the contour of the button port 16b.

[0193] Of course, the light display area can also be in an arc shape or other shapes.

[0194] In the related art, the lampshade and the push button switch of the indicator light 17 are respectively arranged at different positions of the electronic atomization device, and its structure is complicated. On the one hand, the electronic atomization device of this embodiment divides the pressing member 181 into a light-shielding area and a light-displaying area, so that the pressing member 181 can not only control the opening and closing of the power supply component 13 and the indicator light 17 under the action of an external force, but also allow the light of the indicator light 17 to pass through. In this way, the pressing member 181 can not only have the function of a push button switch, but also have the effect of a lampshade. In this way, the internal structure of the electronic atomization device can be greatly simplified, making the structure of the electronic atomization device simple, and saving the internal space of the electronic atomization device. On the other hand, the light-displaying area is arranged circumferentially around the light-shielding area to allow the light of the indicator light 17 to pass through more from the light-displaying area, so that the light transmission effect of the indicator light 17 can be made more uniform.

[0195] In one embodiment, please refer to Figure 12 and Figure 13 The pressing member 181 includes a pressing portion 1811 and a light shielding member 1815. The pressing portion 1811 is located at the key port 16b and is made of a light-transmitting material. The light shielding member 1815 is also made of a light-shielding material. A portion of the end surface of the pressing portion 1811 facing away from the accommodating cavity 16a is recessed to form a recessed area. The light shielding member 1815 is located within the recessed area to form a light-shielding area. Another portion of the end surface of the pressing portion 1811 forms a light display area. This allows the light of the indicator light 17 to pass through the light display area, resulting in a more uniform light display. This also prevents the light shielding member 1815 from falling, thereby improving the installation stability of the light shielding member 1815.

[0196] Specifically, the material type of the pressing portion 1811 is not limited, as long as it allows the light of the indicator light 17 to pass through.

[0197] For example, the pressing portion 1811 may be made of one of silicone, ABS (Acrylonitrile Butadiene Styrene), and PC (Polycarbonate).

[0198] For another example, the material of the pressing portion 1811 also includes astigmatism powder, thereby increasing the transparency of the light display area of ​​the pressing portion 1811, thereby enhancing the brightness of the light of the indicator light 17 when passing through the light display area.

[0199] The material type of the light shielding member 1815 is not limited, as long as it can prevent the light of the indicator light 17 from passing through.

[0200] The projected area of ​​the light shielding member 1815 on the end surface of the pressing portion 1811 away from the accommodating cavity 16a is the range of the light shielding zone, and the projected shape of the light shielding member 1815 on the end surface away from the accommodating cavity 16a is the shape of the light shielding zone.

[0201] The light shielding member 1815 can prevent the light of the indicator light 17 from being emitted through the light shielding area by absorbing the light of the indicator light 17 or reflecting the light of the indicator light 17 .

[0202] The shape of the recessed area is not limited. For example, the cross-sectional shape of the recessed area is circular or square.

[0203] The light shielding member 1815 is located in the recessed area, shielding the light of the indicator light 17 passing through the recessed area. Thus, the recessed area is the light shielding area of ​​the pressing member 181, and the unrecessed part is the light display area of ​​the pressing member 181.

[0204] The depth of the recessed area can be the thickness of the shading member 1815. Therefore, when the shading member 1815 is located in the recessed area, the end face of the shading area away from the accommodating cavity 16a is flush with the end face of the light display area away from the accommodating cavity 16a, which can improve the surface flatness of the electronic atomization device.

[0205] Of course, the depth of the recessed area may also be higher than the thickness of the light shielding member 1815 , or lower than the thickness of the light shielding member 1815 .

[0206] In one embodiment, please refer to Figure 13 The control switch 182 is located in the pressing direction of the pressing member 181. The host module 10 includes multiple indicator lights 17. In a plane perpendicular to the pressing direction, the indicator lights 17 are arranged at intervals around the circumference of the control switch 182. Therefore, by providing multiple indicator lights 17, the phenomenon of point light sources in the electronic atomization device can be prevented, making the lighting display more uniform.

[0207] Specifically, the indicator lights 17 are arranged at circumferential intervals around the control switch 182, and can cooperate with the light display area extending circumferentially around the shading area, so that the light transmission effect of each area of ​​the light display area is better, thereby making the light display more uniform.

[0208] The multiple indicator lights 17 may be located on different planes or on the same plane.

[0209] For example, the control switch 182 and the indicator light 17 are both located on the circuit board 14 , electrically connected to the circuit board 14 , and arranged at intervals along the circumference of the control switch 182 .

[0210] The control switch 182 is connected to the circuit board 14 in any manner. For example, the control switch 182 is fixed to the circuit board 14 by soldering.

[0211] In one embodiment, please refer to Figure 13At least one indicator light 17 is provided on each of two opposing sides of the control switch 182 along the fourth direction, and at least one indicator light 17 is provided on each of two opposing sides of the control switch 182 along the fifth direction. The fourth and fifth directions are perpendicular to each other. Thus, placing the indicator lights 17 on both sides of the control switch 182 in two mutually perpendicular directions can make the lighting display effect of the indicator lights 17 more reliable.

[0212] Specifically, the number of indicator lights 17 provided on two opposite sides of the control switch 182 along the fourth direction may be one or more.

[0213] The number of indicator lights 17 provided on two opposite sides of the control switch 182 along the fifth direction may be one or more.

[0214] In one embodiment, referring to the figure, the pressing portion 1811 is a lampshade. Thus, by integrating the lampshade and the button together, assembly is simplified and less space is occupied.

[0215] In one embodiment, please refer to Figure 13 The pressing portion 1811 includes a first section 1812 and a second section 1813. The first section 1812 is located within the key opening 16b, and the second section 1813 is located on the side of the first section 1812 near the indicator light 17. The outer circumference of the second section 1813 protrudes relative to the outer circumference of the first section 1812 to form a limiting step, which abuts against the main body housing 16. This prevents the pressing portion 1811 from falling out of the key opening 16b, thereby improving the installation stability of the pressing member 181.

[0216] Specifically, the outer circumference of second section 1813 protrudes relative to the outer circumference of first section 1812. That is, in a plane parallel to the end face of first section 1812, the cross-sectional area of ​​second section 1813 is greater than that of first section 1812 and also greater than the cross-sectional area of ​​key opening 16b. As a result, second section 1813 forms a stepped shape relative to the outer circumference of first section 1812, thereby abutting against host housing 16 at key opening 16b, preventing pressing portion 1811 from dislodging from key opening 16b.

[0217] The length by which the outer circumference of the second section 1813 protrudes from the outer circumference of the first section 1812 is not limited, as long as it can abut against the host housing 16 at the button opening 16 b.

[0218] The outer circumference of the second section 1813 may be partially protruding relative to the outer circumference of the first section 1812 to abut against the host housing 16 , or the entire outer circumference may be protruding to abut against the host housing 16 .

[0219] It should be noted that the first section 1812 and the second section 1813 of the pressing portion 1811 can be separate structures. According to actual conditions, the first section 1812 and the second section 1813 of the pressing portion 1811 can also adopt an integrated structure, thereby improving the structural stability of the pressing member 181.

[0220] In one embodiment, please refer to Figure 13 In the projection plane parallel to the end face of the second segment 1813 close to the indicator light 17, the projection of the indicator light 17 is located within the projection range of the second segment 1813. As a result, the light display of the indicator light 17 can be made more uniform, the occurrence of point light sources can be reduced, and the light display effect can be made more reliable.

[0221] That is to say, the indicator lights 17 are all arranged within the coverage of the second section 1813, which can facilitate the light emitted by the indicator lights 17 to pass through the second section 1813 more conveniently. From the perspective of projection, the projection of the indicator lights 17 is located within the projection range of the second section 1813.

[0222] It should be noted that, the projection of only a part of the area of ​​the indicator light 17 may be located within the projection range of the light display area, or the projection of the entire area may be located within the projection range of the light display area.

[0223] In one embodiment, the distance between the indicator light 17 and the second segment 1813 is greater than or equal to 3 mm and less than or equal to 6 mm, such as 3 mm, 4 mm, 5 mm, or 6 mm. This can avoid the phenomenon of uneven lighting of the indicator light 17 caused by the distance between the indicator light 17 and the second segment 1813 being too large or too small.

[0224] In one embodiment, please refer to Figure 13 The pressing portion 1811 further includes a pressing rod 1814, which is disposed on a side of the second section 1813 near the indicator light 17. The control switch 182 is disposed on a side of the pressing rod 1814 away from the second section 1813 and spaced apart from the end of the pressing rod 1814 away from the second section 1813. When the pressing rod 1814 contacts the control switch 182 under the action of an external force, the indicator light 17 switches between on and off. Thus, the pressing rod 1814 cooperates with the control switch 182 to switch the indicator light 17 between on and off.

[0225] Specifically, the second section 1813 is located between the first section 1812 and the pressing rod 1814. Furthermore, the control switch 182 is disposed on one side of the pressing rod 1814 along the pressing direction. Thus, by applying external force to the pressing portion 1811, the pressing rod 1814 can be moved in the pressing direction to contact the control switch 182, thereby turning the indicator light 17 on and off.

[0226] Under the action of external force, the first section 1812 and the second section 1813 drive the pressing rod 1814 in any manner.

[0227] For example, the first section 1812 is located in the button opening 16b and can move relative to the button opening 16b. Under the action of external force, the first section 1812 moves toward the accommodating cavity 16a, thereby driving the pressing rod 1814 to move, and then cooperate with the control switch 182 to switch the indicator light 17 between on and off.

[0228] For another example, the step formed by the first section 1812 and the second section 1813 is fixedly connected to the main housing 16. Under the action of external force, the main housing 16 undergoes elastic deformation, thereby driving the pressing rod 1814 to move, and then cooperates with the control switch 182 to switch the indicator light 17 between on and off.

[0229] In a natural state, that is, without the action of external force, a gap is formed between the end of the pressing rod 1814 close to the indicator light 17 and the control switch 182 by the interval setting, which can prevent accidental touch from changing the on or off state of the indicator light 17.

[0230] In one embodiment, please refer to Figure 14 and Figure 15 The atomizer module 20 includes a first one-way valve 27. The atomizer housing 22 has a liquid channel 22d and an air hole 22e. The liquid storage chamber 22a is connected to the outside through the air hole 22e; the opposite ends of the liquid channel 22d are respectively connected to the liquid storage chamber 22a and the nozzle 23. At least a part of the first one-way valve 27 is arranged in the liquid storage chamber 22a, and is movably arranged at the connection between the liquid storage chamber 22a and the air hole 22e.

[0231] The first one-way valve 27 has a blocking state and a conducting state. When the first one-way valve 27 is in the blocking state, the first one-way valve 27 blocks the air hole 22e; when the first one-way valve 27 is in the conducting state, the first one-way valve 27 conducts the air hole 22e to allow external air flow to enter the liquid storage chamber 22a through the air hole 22e; the first one-way valve 27 switches between the blocking state and the conducting state by moving relative to the air hole 22e.

[0232] Thus, on the one hand, the provision of air holes 22e facilitates external airflow into the liquid storage chamber 22a through the air holes 22e, thereby balancing the air pressure inside and outside the liquid storage chamber 22a, thereby facilitating liquid discharge. On the other hand, a first one-way valve 27 is provided at the connection between the liquid storage chamber 22a and the air holes 22e. When blocked, the first one-way valve 27 can block the air holes 22e, reducing the risk of atomized liquid in the liquid storage chamber 22a flowing out of the liquid storage chamber 22a through the air holes 22e, thereby significantly improving the sealing effect within the liquid storage chamber 22a. Furthermore, when the first one-way valve 27 is in the open state, it can keep the air holes 22e unobstructed, facilitating external airflow into the liquid storage chamber 22a through the air holes 22e, thereby replenishing gas within the liquid storage chamber 22a. This also allows for smooth atomization at the nozzle 23, reducing the occurrence of undesirable phenomena such as intermittent mist discharge, lack of mist, or pulsed atomization due to negative pressure within the liquid storage chamber 22a. Since the first one-way valve 27 is provided at the connection point between the liquid storage chamber 22a and the air hole 22e, it only has the function of introducing the external airflow into the liquid storage chamber 22a in the conductive state, thereby further reducing the risk of the atomized liquid in the liquid storage chamber 22a flowing out of the liquid storage chamber 22a through the air hole 22e, thereby achieving a better sealing effect.

[0233] Specifically, the liquid channel 22d is a channel connecting the liquid storage chamber 22a and the nozzle 23 respectively, so as to enable the atomized liquid in the liquid storage chamber 22a to move to the nozzle 23 under the action of air pressure and then be atomized.

[0234] The air hole 22e on the atomizing shell 22 is used to connect the liquid storage chamber 22a with the outside, so that the outside gas can enter the liquid storage chamber 22a to balance the air pressure inside and outside the liquid storage chamber 22a, thereby facilitating the atomized liquid in the liquid storage chamber 22a to flow out.

[0235] The first one-way valve 27 refers to a valve structure that allows external airflow to enter the liquid storage chamber 22a through the air hole 22e only in the conduction state.

[0236] Specifically, in the blocked state, the first one-way valve 27 blocks the air hole 22e, and the external air flow cannot enter the liquid storage chamber 22a through the air hole 22e, and the atomized liquid in the liquid storage chamber 22a cannot flow out through the air hole 22e.

[0237] In the on state, the first one-way valve 27 is connected to the air hole 22e, so that external air can enter the liquid storage chamber 22a through the air hole 22e, while the atomized liquid in the liquid storage chamber 22a cannot flow out through the air hole 22e.

[0238] It should be noted that the specific manner in which the first one-way valve 27 communicates with the air hole 22e is not limited, and it only needs to ensure that the air hole 22e is connected to the liquid storage chamber 22a to allow external air to flow into the liquid storage chamber 22a.

[0239] For example, the first one-way valve 27 avoids the air hole 22e as a whole so that the air hole 22e is completely open. In another example, the first one-way valve 27 avoids the air hole 22e in a local area so that a part of the air hole 22e is open.

[0240] The first one-way valve 27 may have its entire area located within the liquid storage chamber 22 a , or may have a partial area located within the liquid storage chamber 22 a and a partial area located outside the liquid storage chamber 22 a .

[0241] Furthermore, the first one-way valve 27 may be entirely disposed at the connection between the liquid storage chamber 22a and the air hole 22e and movable relative to the air hole 22e, or partially disposed at the connection between the liquid storage chamber 22a and the air hole 22e and movable relative to the air hole 22e.

[0242] The first one-way valve 27 can switch between a blocking state and a conducting state by moving relative to the air hole 22e. The specific form of the movement of the first one-way valve 27 relative to the air hole 22e is not limited, such as rotation, translation, elastic deformation, sliding, etc.

[0243] It should be noted that the specific structure of the first one-way valve 27 is not limited. Depending on the structure, the manner in which the first one-way valve 27 is moved relative to the air hole 22e may vary. For example, the first one-way valve 27 may be moved relative to the air hole 22e by the pressure differential between the liquid storage chamber 22a and the outside world. Switching the first one-way valve 27 by the pressure differential can simplify the specific structure of the first one-way valve 27 while better meeting the need to replenish external air into the liquid storage chamber 22a.

[0244] Of course, the first one-way valve 27 may also adopt other structural types, such as a solenoid valve or other valve structures.

[0245] The material of the first one-way valve 27 can also be set according to actual conditions. For example, the material of the first one-way valve 27 is one of silicone, air rubber, and fluorosilicone. In this way, the first one-way valve 27 can have good elastic deformation ability and good sealing effect.

[0246] For another example, the hardness of the first one-way valve 27 is greater than or equal to 40 Shore A and less than or equal to 80 Shore A, such as 40 Shore A, 60 Shore A, or 80 Shore A. Thus, the first one-way valve 27 can have a relatively good hardness.

[0247] The sizes of the first one-way valve 27 and the air hole 22e can also be set according to actual conditions.

[0248] For example, the diameter of the area of ​​the first one-way valve 27 located within the liquid storage chamber 22a is greater than or equal to 6 mm and less than or equal to 9 mm, such as 6 mm, 8 mm, or 9 mm. These dimensions facilitate manufacturing while also matching conventional liquid storage chambers 22a and air holes 22e.

[0249] For another example, the diameter of the air hole 22e is greater than or equal to 0.5 mm and less than or equal to 1 mm, such as 0.5 mm, 0.8 mm, or 1 mm. The above dimensions facilitate manufacturing and are compatible with the conventional liquid storage chamber 22a and the first one-way valve 27.

[0250] In one embodiment, please refer to Figure 15 The atomizing shell 22 includes a mounting wall 225 having an air hole 22e. The mounting wall 225 has a first wall surface 225a located in the liquid storage chamber 22a. The first one-way valve 27 includes a first valve body 271. The first valve body 271 is located in the liquid storage chamber 22a and is detachably attached to the first wall surface 225a. The air hole 22e is located within the coverage range of the first valve body 271, so that the first one-way valve 27 is in a blocked state.

[0251] When the electronic atomization device is working, under the action of the air pressure difference, a part of the first valve body 271 is separated from the first wall 225a through elastic deformation, so that the first one-way valve 27 is switched to the conducting state.

[0252] Specifically, the mounting wall 225 is a wall on one side of the atomizing housing 22 having the air hole 22e. The air hole 22e passes through the mounting wall 225 to connect the liquid storage chamber 22a with the outside when the first one-way valve 27 does not block the air hole 22e.

[0253] In practice, the first valve body 271 is detachably attached to the wall area of ​​the atomizing housing 22 at the connection between the liquid storage chamber 22a and the air hole 22e, thereby covering the air hole 22e. Therefore, the coverage area and cross-sectional dimensions of the first valve body 271 are larger than the cross-sectional dimensions of the air hole 22e.

[0254] Therefore, when the electronic atomization device is working, the air compressor 11 supplies air to the nozzle 23 through the air channel 22b, and a negative pressure (such as a negative pressure of -1KPa to -4Kpa) is formed in the liquid channel 22d, so that the atomized liquid inside the liquid storage chamber 22a is liquid. As the atomized liquid is gradually consumed, the negative pressure in the liquid storage chamber 22a gradually decreases, and the air pressure difference between the liquid storage chamber 22a and the outside world also gradually increases. When the air pressure difference reaches the set air pressure range, the first one-way valve 27 switches to the conductive state, and a part of the first valve body 271 undergoes elastic deformation and separates from the first wall 225a, so that the liquid storage chamber 22a is connected to the outside world through the air hole 22e, and then the external air flow can enter the liquid storage chamber 22a through the air hole 22e. As a result, the atomization at the nozzle 23 can be carried out smoothly, and the occurrence of undesirable phenomena such as intermittent mist, no mist or atomization pulses due to the negative pressure in the liquid storage chamber 22a can be reduced.

[0255] It should be noted that when the air pressure in the liquid storage chamber 22a is greater than or equal to the external air pressure, or when the pressure difference between the liquid storage chamber 22a and the external air pressure does not reach the set pressure range, the first valve body 271 abuts against the first wall 225a, thereby separating the air hole 22e from the liquid storage chamber 22a. Thus, a good sealing effect can be achieved.

[0256] The structural shape of the first valve body 271 can be set according to actual conditions.

[0257] For example, see Figure 15 and Figure 16 The side of the first valve body 271 facing away from the air hole 22e is a curved surface 271a. From the middle region to the peripheral edge of the first valve body 271, the curved surface 271a curves toward the side closer to the first wall 225a. In other words, the side surface of the first valve body 271 facing away from the first wall 225a is a curved surface 271a, and it curves gradually from the middle to the periphery toward the side closer to the first wall 225a. The formation of the curved surface 271a further enhances the sealing effect.

[0258] Of course, in other embodiments, the side of the first valve body 271 facing away from the air hole 22e may also be an inclined surface.

[0259] For example, the cross-sectional dimensions of the first valve body 271 gradually decrease from its central region to its circumferential edge. In other words, the first valve body 271 employs a structure that gradually tapers from its central region toward its periphery. Consequently, under the influence of the pressure differential between the interior and exterior of the liquid storage chamber 22a, the thinning of the circumferential edge of the first valve body 271 facilitates elastic deformation of the circumferential edge, separating at least a portion of the circumferential edge from the first wall 225a, thereby maintaining the connection between the air holes 22e.

[0260] The air hole 22e is located within the coverage of the first valve body 271, and its specific position relative to the first valve body 271 can be set according to actual conditions.

[0261] For example, see Figure 16 The first valve body 271 includes a transition section 2711 located between the middle area and the circumferential edge, the air hole 22e is located within the coverage of the transition section 2711, and the middle area of ​​the first valve body 271 is fixed to the mounting wall 225.

[0262] In other words, the air hole 22e is not located directly within the coverage of the central region or the circumferential edge of the first valve body 271, but rather within the coverage of the transition section 2711 between the two. This facilitates the fixing of the central region of the first valve body 271 to the mounting wall 225, without interfering with the installation of the first valve body 271. Furthermore, the placement of the air hole 22e at the circumferential edge of the first valve body 271 prevents any impact on the sealing and waterproofing properties of the first valve body 271.

[0263] In one embodiment, please refer to Figure 15 The first valve body 271 has a fitting surface 271b that fits with the first wall 225a. The first one-way valve 27 also includes a positioning column 272 arranged on the fitting surface 271b. The mounting wall 225 has a positioning hole that communicates with the liquid storage chamber 22a. The positioning column 272 is passed through the positioning hole to cooperate with the positioning hole so that the air hole 22e is located within the coverage range of the first valve body 271.

[0264] Specifically, the positioning hole and the air hole 22 e are staggered with each other, thereby allowing the air hole 22 e and the positioning column 272 to avoid each other.

[0265] At the same time, the positioning post 272 is inserted into the positioning hole to fit in the positioning hole. On the one hand, it can facilitate the first valve body 271 to cover the air hole 22e, so as to facilitate the installation of the first one-way valve 27. On the other hand, it can also enable the first valve body 271 to be firmly installed on the installation wall 225 and not easily misplaced.

[0266] It should be noted that the positioning post 272 is inserted into the positioning hole. The positioning post 272 may be detachably disposed in the positioning hole or may be non-detachably disposed in the positioning hole.

[0267] For example, the positioning post 272 passes through the positioning hole and is engaged with the mounting wall 225 .

[0268] For another example, the positioning post 272 is passed through the positioning hole and is threadedly connected to the mounting wall 225 .

[0269] The end of the positioning hole away from the liquid storage cavity 22a can be a closed end or an open end communicating with the outside.

[0270] For example, see Figure 15 and Figure 16 One end of the positioning hole away from the liquid storage chamber 22a is connected to the outside world, the positioning column 272 is stuck in the positioning hole and blocks the positioning hole, and one end of the positioning column 272 away from the fitting surface 271b extends out of the positioning hole to form a protruding end 2721.

[0271] Specifically, the positioning post 272 is inserted into the positioning hole to engage with the mounting wall 225 and seal the positioning hole to prevent the atomized liquid in the liquid storage cavity 22a from flowing out through the positioning hole.

[0272] By extending one end of the positioning post 272 away from the fitting surface 271 b out of the positioning hole, the positioning post 272 can be better passed through the positioning hole, so that the first one-way valve 27 can be installed on the installation wall 225.

[0273] In one embodiment, please refer to Figure 15 and Figure 16 The mounting wall 225 has a second wall 225b away from the first wall 225a, and a partial area of ​​the protruding end 2721 protrudes to form an inverted position 2722. The outer dimensions of the inverted position 2722 are larger than the opening size of the positioning hole, and the inverted position 2722 abuts against the second wall 225b.

[0274] Specifically, the second wall surface 225 b is a side of the installation wall 225 opposite to the first wall surface 225 a , that is, the first wall surface 225 a and the second wall surface 225 b are wall surfaces on opposite sides of the installation wall 225 .

[0275] A protruding undercut 2722 is formed on one end of the positioning post 272 facing away from the fitting surface 271b. In the area where the positioning hole is located at the second wall 225b, since the size of the undercut 2722 is larger than the opening size of the positioning hole, the undercut 2722 abuts against the second wall 225b, making it difficult for the undercut 2722 to pass through the positioning hole under the action of the air pressure difference. Therefore, when the electronic atomization device is working, under the action of the air pressure difference, a part of the first valve body 271 is separated from the first wall 225a through elastic deformation, allowing the air flow to be replenished into the liquid storage chamber 22a through the air hole 22e. Since the undercut 2722 abuts against the second wall 225b, it is possible to limit the first valve body 271. In this way, while a part of the first valve body 271 is separated from the first wall 225a through elastic deformation, it will not completely detach from the first wall 225a due to the air pressure difference. At the same time, when the electronic atomization device stops working, it can also avoid the situation where the first one-way valve 27 cannot be switched back to the blocked state.

[0276] In one embodiment, the undercut portion 2722 is made of an elastically deformable material. During installation of the first one-way valve 27, the undercut portion 2722 can be elastically deformed to pass through the positioning hole from one side of the liquid storage chamber 22a to abut against the second wall 225b. This facilitates better installation of the first one-way valve 27.

[0277] In a specific embodiment, during the installation of the first one-way valve 27, the protruding end 2721 is inserted into the positioning hole from one side of the liquid storage chamber 22a. When the undercut position 2722 reaches the connection between the positioning hole and the liquid storage chamber 22a, the protruding end 2721 passes through the positioning hole to the outside world. The protruding end 2721 is pulled by hand or a clamp, causing the undercut position 2722 to elastically deform and pass through the positioning hole until it reaches the connection between the positioning hole and the outside world. At this time, the undercut position 2722 returns to its original state, thereby abutting against the second wall 225b. In this way, the purpose of preventing the first one-way valve 27 from falling out can be achieved, and its overall assembly is simple, efficient, and low-cost.

[0278] It should be noted that, in some embodiments, the portion of the protruding end 2721 below the undercut portion 2722 may be cut off to reduce interference of the protruding end 2721 with other structures.

[0279] In one specific embodiment, the atomizing housing 22 includes a top cover, an atomizing cartridge 221, and a dustproof sealing cover 412 having a mounting cavity 12a. One end of the mounting cavity 12a is open to form a mounting inlet 12b. The atomizing cartridge 221 includes a main body of the atomizing cartridge 221 and a connector 222 for the atomizing cartridge 221. The main body of the atomizing cartridge 221 and the connector 222 for the atomizing cartridge 221 together form a liquid storage cavity 22a. The air hole 22e is located on the connector 222 for the atomizing cartridge 221. The atomizing cartridge 221 is located within the mounting cavity 12a, and the connector 222 for the atomizing cartridge 221 is located on one side of the mounting inlet 12b. The top cover is located at the mounting inlet 12b and has a port connecting the air hole 22e to the outside world.

[0280] The atomizer module 20 may further include a comb assembly 224 . The comb assembly 224 is located in the mounting cavity 12 a and on a side of the atomizer bomb 221 body that is away from the adapter 222 of the atomizer bomb 221 .

[0281] In one embodiment, please refer to Figure 18 The atomizer module 20 includes a sealing assembly 26, the atomizer housing 22 has a first liquid injection port 22c, the liquid storage chamber 22a is connected to the first liquid injection port 22c, and at least a portion of the sealing assembly 26 can move relative to the first liquid injection port 22c to switch between a blocked state located at the first liquid injection port 22c and an open state avoiding the first liquid injection port 22c; when the sealing assembly 26 is in the open state, the sealing assembly 26 is connected to the atomizer housing 22.

[0282] This can prevent the sealing assembly 26 from being lost due to falling during the liquid filling process of the atomizer module 20. It can also prevent the sealing assembly 26 from being contaminated by falling to the ground during the liquid filling process. This can minimize contamination of the atomized liquid in the liquid storage chamber 22a by the sealing assembly 26 when the sealing assembly 26 seals the liquid storage chamber 22a.

[0283] Specifically, the sealing assembly 26 can block the first liquid injection port 22c communicating with the liquid storage chamber 22a to prevent the atomized liquid from flowing out of the liquid storage chamber 22a from the first liquid injection port 22c.

[0284] The atomized liquid in the liquid storage chamber 22a is transferred to the nozzle 23 and atomized to form an aerosol under the action of the high-speed airflow provided by the air compressor 11. At least a portion of the sealing component 26 is movable relative to the first liquid injection port 22c to switch between a blocked state and an open state.

[0285] According to actual conditions, only a portion of the sealing component 26 may be movable relative to the first liquid injection port 22 c so as to switch between blocking the first liquid injection port 22 c and opening the first liquid injection port 22 c.

[0286] Similarly, the sealing assembly 26 can also be entirely movable relative to the first liquid injection port 22c to switch between blocking the first liquid injection port 22c and opening the first liquid injection port 22c. Furthermore, when the sealing assembly 26 is entirely movable relative to the first liquid injection port 22c, the sealing assembly 26 and the atomizing housing 22 remain connected.

[0287] In the blocking state, at least a portion of the sealing assembly 26 is located at the first liquid injection port 22c to block the first liquid injection port 22c. Thus, the sealing assembly 26 can retain the atomized liquid in the liquid storage chamber 22a and prevent the atomized liquid from flowing out of the first liquid injection port 22c.

[0288] It should be noted that there is no limitation on the manner in which the sealing assembly 26 seals the first liquid injection port 22 c.

[0289] For example, the sealing component 26 can slide relative to the first liquid injection port 22c, and the first liquid injection port 22c is sealed by the sealing component 26 being in close contact with the end surface of the first liquid injection port 22c.

[0290] For another example, the sealing component 26 may also block the first liquid injection port 22 c by penetrating at least a portion of the sealing component 26 into the first liquid injection port 22 c.

[0291] In the open state, at least a portion of the sealing assembly 26 is separated from the first liquid injection port 22c to avoid the first liquid injection port 22c, thereby allowing the liquid storage chamber 22a to communicate with the outside world through the first liquid injection port 22c. This makes it convenient for a user to inject atomized liquid into the liquid storage chamber 22a through the first liquid injection port 22c.

[0292] It should be noted that, no matter in the blocked state or the opened state, the sealing assembly 26 is connected to the atomizing housing 22 , thereby preventing the sealing assembly 26 from falling off.

[0293] According to actual conditions, the connection position of the sealing assembly 26 and the atomizing housing 22 is not limited.

[0294] For example, the sealing assembly 26 can be connected to the side of the atomizing housing 22, or to the end surface of the atomizing housing 22 having the first liquid injection port 22c. It is sufficient that when the sealing assembly 26 is in the open state, the sealing assembly 26 and the atomizing housing 22 are in the connected state.

[0295] In one embodiment, please refer to Figure 17 and Figure 18 The sealing assembly 26 includes a first sealing member 261, a connecting member 262, and a fixing member 263. The fixing member 263 is fixed to the end face of the atomizer housing 22 having the first liquid injection port 22c. The connecting member 262 is respectively connected to the first sealing member 261 and the fixing member 263. The first sealing member 261 is movably disposed at the first liquid injection port 22c. Thus, by fixing the fixing member 263 to the atomizer body 201 and connecting the fixing member 263 and the first sealing member 261 via the connecting member 262, the first sealing member 261 can be prevented from falling when the sealing assembly 26 is in the open state, thereby preventing the first sealing member 261 from being lost or causing contamination of the atomized liquid in the liquid storage chamber 22a.

[0296] Specifically, the fixing member 263 and the first liquid injection port 22 c are located on the end surface of the same end of the atomizing housing 22 .

[0297] The specific structure of the first sealing member 261 is not limited. For example, the first sealing member 261 is a sealing plug.

[0298] The specific shape and size of the first sealing member 261 are not limited.

[0299] For example, the first sealing member 261 is circular.

[0300] For another example, the diameter of the first sealing member 261 is 4 mm to 6 mm.

[0301] The specific material and structure of the connecting member 262 are not limited, as long as it can connect the first sealing member 261 and the fixing member 263 to prevent the first sealing member 261 from falling when the sealing assembly 26 is in the open state.

[0302] Exemplarily, the connecting member 262 is made of an elastic material, such as a silicone material or a rubber material. This allows the connecting member 262 to have a certain degree of deformation ability, thereby better sealing the first liquid injection port 22c.

[0303] For example, the hardness of the connector 262 is greater than or equal to 40 Shore A and less than or equal to 85 Shore A. For example, the hardness of the connector 262 is 40 Shore A, 70 Shore A, or 85 Shore A. This can minimize the hardness of the connector 262, which could cause the connector 262 to soften and deform, slowing down the wear of the connector 262. It can also minimize the hardness of the connector 262, which could cause the connector 262 to break due to poor elastic deformation, resulting from poor elastic deformation.

[0304] By providing the connecting member 262, the fixing member 263 can be conveniently provided at other areas of the end surface of the atomizing body 201. Thus, when the user injects liquid into the liquid storage chamber 22a from the first liquid injection port 22c through the liquid injection device, the interference of the sealing assembly 26 on the liquid injection process can be reduced.

[0305] The specific position where the fixing member 263 is disposed on the end surface of the atomizing body 201 is not limited.

[0306] For example, see Figure 17 and Figure 18 The atomizer housing 22 has a second air inlet 20a formed on the end surface thereof having the first liquid injection port 22c. The air compressor 11 communicates with the air passage 22b through the second air inlet 20a. The first liquid injection port 22c and the fixing member 263 are located on opposite sides of the second air inlet 20a. At least a portion of the connecting member 262 is curved to avoid the second air inlet 20a when the sealing assembly 26 is in the blocked state. As a result, when injecting liquid into the liquid storage chamber 22a, the sealing assembly 26 can avoid the first liquid injection port 22c, making injection more convenient and smooth.

[0307] Specifically, the first liquid injection port 22c and the fixing member 263 are respectively located on opposite sides of the second air inlet 20a, so that the first sealing member 261 can avoid the first liquid injection port 22c to a large extent when the sealing assembly 26 is in the open state, thereby further reducing the interference of the sealing assembly 26 on the liquid injection process.

[0308] The first sealing member 261 avoids the first liquid injection port 22 c means that when the sealing assembly 26 is in the open state, the first sealing member 261 does not block the first liquid injection port 22 c, so as to facilitate the injection of liquid into the liquid storage cavity 22 a.

[0309] The connecting member 262 may be partially curved or entirely curved, as long as the connecting member 262 can avoid the second air inlet 20a when the sealing assembly 26 is in the blocking state.

[0310] Exemplarily, the connecting member 262 is an arc-shaped connecting arm.

[0311] It should be noted that the second air inlet 20a is an airflow inlet for air to enter the atomizer module 20. Depending on the specific type of the atomizer module 20, the effect of the airflow flowing into the atomizer module 20 from the second air inlet 20a may vary.

[0312] For example, the air compressor 11 is configured to supply a high-speed airflow to the nozzle 23 through the second air inlet 20a. The nozzle 23 is respectively connected to the second air inlet 20a and the liquid storage chamber 22a, so that the airflow from the air compressor 11 atomizes the atomized liquid in the liquid storage chamber 22a to generate an aerosol, and the aerosol is then supplied to the outside of the atomizer module 20. In other words, the airflow flowing from the second air inlet 20a into the atomizing body 201 can, on the one hand, atomize the atomized liquid through high-speed flow to form an aerosol, and on the other hand, can cause the aerosol to flow out of the atomizer module 20.

[0313] In other embodiments, the electronic atomization device can also atomize the atomized liquid through an atomization component arranged in the atomization body 201, and the airflow flowing in from the second air inlet 20a only serves to mix with the atomized atomized liquid to form an aerosol and carry it out of the atomizer module 20.

[0314] The specific size of the connecting member 262 can also be set according to actual conditions.

[0315] In one embodiment, the width of the connector 262 is greater than or equal to 2 mm and less than or equal to 3 mm. For example, the width of the connector 262 is 2 mm, 2.5 mm, or 3 mm. This prevents material waste caused by the connector 262 being too wide and reduces the risk of damage to the connector 262 due to its small width.

[0316] In one embodiment, the thickness of the connector 262 is greater than or equal to 0.5 mm and less than or equal to 1.5 mm. For example, the width of the connector 262 is 0.5 mm, 1 mm, or 1.5 mm. This prevents material waste caused by excessive thickness of the connector 262 and reduces the risk of damage to the connector 262 due to its thinness.

[0317] In one embodiment, please refer to Figure 19The first sealing member 261 includes a second abutting portion 2611 and a sealing portion 2612. When the sealing assembly 26 is in the blocking state, the sealing portion 2612 is at least partially inserted into the first liquid inlet 22c to seal with the first liquid inlet 22c. The second abutting portion 2611 is located outside the first liquid inlet 22c and is connected to the connector 262. At the junction of the second abutting portion 2611 and the sealing portion 2612, the second abutting portion 2611 has an abutting surface 121a that abuts against the outer end surface of the first liquid inlet 22c. On the one hand, by inserting the sealing portion 2612 into the first liquid inlet 22c, the first liquid inlet 22c can be blocked. On the other hand, by the second abutting portion 2611 abutting against the first liquid inlet 22c, the risk of the first sealing member 261 completely entering the liquid storage chamber 22a due to improper operation can be reduced when the sealing portion 2612 blocks the first liquid inlet 22c.

[0318] Specifically, a portion of the sealing portion 2612 may be located in the first liquid injection port 22 c so as to seal the first liquid injection port 22 c by sealingly cooperating with the first liquid injection port 22 c.

[0319] The entire area of ​​the sealing portion 2612 may also be located in the first liquid injection port 22 c, so as to seal the first liquid injection port 22 c by sealingly cooperating with the first liquid injection port 22 c.

[0320] The sealing method of the sealing portion 2612 and the first liquid injection port 22c is not limited.

[0321] For example, the side wall of the sealing part 2612 has an external thread, and the first liquid injection port 22c has an internal thread that cooperates with the external thread. The sealing part 2612 is arranged in the first liquid injection port 22c, and the external thread and the internal thread are tightly matched by rotation to seal the first liquid injection port 22c.

[0322] It should be noted that the second abutting portion 2611 and the sealing portion 2612 can be integrally formed or separately formed.

[0323] Furthermore, the connection method between the second abutting portion 2611 and the connecting member 262 is not limited.

[0324] Exemplarily, the second abutting portion 2611 is fixedly connected to the connecting member 262 .

[0325] Illustratively, the second abutting portion 2611 is movably connected to the connecting member 262 , and the second abutting portion 2611 is freely rotatable at the connection with the connecting member 262 .

[0326] It is understandable that the size of the abutting surface 121a is larger than the size of the outer end surface of the first liquid injection port 22c, so that when the sealing assembly 26 is in the blocked state, the second abutting portion 2611 abuts against the outer end surface of the first liquid injection port 22c.

[0327] For example, the outer end face of the first liquid injection port 22c is circular with a diameter of 4 mm, and the abutting surface 121a is also circular with a diameter of 5 mm to 8 mm, thereby enabling the second abutting portion 2611 to abut against the outer end face of the first liquid injection port 22c.

[0328] In one embodiment, please refer to Figure 19 The first sealing member 261 is detachably disposed through the first liquid inlet 22c. A portion of the outer surface of the first sealing member 261 protrudes to form a sealing protrusion 2613 extending along the outer circumference of the first sealing member 261. When the sealing assembly 26 is in the blocking state, the sealing protrusion 2613 is located within the first liquid inlet 22c, forming an interference fit with the inner wall of the first liquid inlet 22c. Thus, the interference fit between the sealing protrusion 2613 and the inner wall of the first liquid inlet 22c provides a better blocking effect on the first liquid inlet 22c.

[0329] Specifically, the sealing protrusion 2613 is arranged along the circumference of the first sealing member 261 , and the position where the sealing protrusion 2613 is arranged is located in the area where the first sealing member 261 seals and cooperates with the inner wall of the first liquid injection port 22 c .

[0330] The number of sealing protrusions 2613 is not limited. The outer surface of the first sealing member 261 may have only one sealing protrusion 2613. Depending on the actual situation, the outer surface of the first sealing member 261 may have multiple sealing protrusions 2613, each sealing protrusion 2613 being spaced apart along the axial direction of the first sealing member 261.

[0331] The sealing protrusion 2613 has a certain deformation ability. When the user uses the first sealing member 261 to seal the first liquid filling port 22c, the sealing protrusion 2613 can be squeezed and deformed, so that after the first sealing member 261 is inserted into the first liquid filling port 22c, it has an interference fit with the inner wall of the first liquid filling port 22c, thereby further improving the sealing effect.

[0332] In one embodiment, please refer to Figure 19 The outer circumference of the second abutting portion 2611 is partially recessed to form a force-applying groove 261a. Thus, by providing the groove, it is convenient for the user to apply force during the process of extracting the first sealing member 261, so that the user can easily separate the first sealing member 261 from the first liquid injection port 22c.

[0333] Specifically, the outer peripheral surface of the second abutting portion 2611 may be partially recessed to form the force-applying groove 261 a , or may be recessed along the circumferential direction of the outer peripheral surface to form the force-applying groove 261 a .

[0334] The number of the force applying grooves 261a is not limited. For example, there can be one or more force applying grooves 261a.

[0335] The force-applying groove 261 a refers to a recessed area on the outer circumference of the abutting surface 121 a , which facilitates applying force when the sealing portion 2612 is pulled out from the first liquid injection port 22 c , so as to convert the sealing assembly 26 from a blocked state to an open state.

[0336] In one embodiment, please refer to Figure 20 and Figure 21 One of the atomizer module 20 and the host module 10 includes a first clamping portion 21 , and the other includes a second clamping portion 161 .

[0337] The first engaging portion 21 has a first connecting slot 21 a having an opening. The second engaging portion 161 is slidably disposed in the first connecting slot 21 a through the opening and engaged with the first engaging portion 21 to detachably connect the atomizer module 20 to the main unit module 10 .

[0338] Thus, on the one hand, by sliding the second engaging portion 161 within the first connecting slot 21a and then engaging with the first engaging portion 21, the connection between the atomizer module 20 and the main unit module 10 can be made tighter. On the other hand, by providing the first connecting slot 21a with an opening, the second engaging portion 161 can slide from the opening into the first connecting slot 21a, thereby assembling the atomizer module 20 and the main unit module 10. Simultaneously, the second engaging portion 161 in the first connecting slot 21a can also slide out of the opening, thereby separating the atomizer module 20 from the main unit module 10. This further improves the ease of assembly and disassembly between the atomizer module 20 and the main unit module 10.

[0339] Specifically, the host module 10 is the host part of the electronic atomization device, and its specific structure is not limited.

[0340] For example, the host module 10 further includes a control component 18 , the power component 13 and the control component 18 are electrically connected, and the control component 18 controls the opening and closing of the electronic atomization device by controlling the circuit of the power component 13 .

[0341] By sliding the second clamping portion 161 from the opening to the first connecting slot 21 a , the first clamping portion 21 and the second clamping portion 161 can be clamped together, thereby achieving the assembly of the atomizer module 20 and the main unit module 10 .

[0342] At the same time, the second clamping portion 161 in the first connecting slot 21 a slides out from the opening, thereby separating the first clamping portion 21 and the second clamping portion 161 , thereby separating the atomizer module 20 from the main unit module 10 .

[0343] The opening position of the first connecting slot 21a is not limited. According to actual conditions, the opening can be formed by partially opening the end of the first connecting slot 21a or partially opening the wall of the first connecting slot 21a near the atomizer module 20.

[0344] It should be noted that, depending on the specific structures of the main unit module 10 and the atomizer module 20 , the manner in which the second clamping portion 161 is achieved through relative movement between the main unit module 10 and the atomizer module 20 is different.

[0345] For example, the main unit module 10 and the atomizer module 20 may be relatively rotated so that the second engaging portion 161 slides into and out of the first connecting slot 21 a , thereby achieving assembly and disassembly between the main unit module 10 and the atomizer module 20 .

[0346] For another example, the main unit module 10 and the atomizer module 20 may be assembled and disassembled by relative translation, so that the second engaging portion 161 slides into and out of the first connecting slot 21 a .

[0347] The specific positions of the first clamping portion 21 and the second clamping portion 161 are set according to actual conditions.

[0348] For example, the host module 10 includes a first clamping portion 21 , and the atomizer module 20 includes a second clamping portion 161 .

[0349] For another example, the host module 10 includes the second clamping portion 161 , and the atomizer module 20 includes the first clamping portion 21 .

[0350] Illustratively, the atomizer module 20 includes a first clamping portion 21, the host module 10 includes a host housing 16, and the end of the host housing 16 close to the atomizing shell 22 includes a second clamping portion 161. The first clamping portion 21 is arranged on the end face of the atomizing shell 22 close to the host module 10, and the first connecting slot 21a extends circumferentially along the end face of the atomizing shell 22.

[0351] Specifically, the atomizing housing 22 can store atomizing liquid so as to atomize the atomizing liquid to generate aerosol.

[0352] The second clamping portion 161 may be located at a port of the main housing 16 at one end close to the atomizer module 20 , or may be at a certain distance from the port.

[0353] By setting the first clamping portion 21 on the end face of the atomizing shell 22 and setting the second clamping portion 161 at one end of the main body shell 16, the first clamping portion 21 and the second clamping portion 161 can be easily docked, so as to facilitate the installation of the atomizing shell 22 on the main body shell 16.

[0354] At the same time, since the first connecting slot 21a extends circumferentially along the end surface of the atomizing shell 22, the main unit module 10 and the atomizer module 20 can rotate relative to each other to enable the second clamping portion 161 to slide relative to the first connecting slot 21a, thereby achieving disassembly and assembly between the main unit module 10 and the atomizer module 20.

[0355] The specific structural forms of the first clamping portion 21 and the second clamping portion 161 can be set according to actual conditions.

[0356] In one embodiment, please refer to Figure 20 and Figure 21 The outer wall of the first clamping portion 21 is partially recessed to form a first connecting slot 21a. This facilitates the processing and manufacturing of the first clamping portion 21 and reduces the weight of the electronic atomization device.

[0357] Of course, in other embodiments, the first connecting slot 21 a may also be formed by protruding a portion of the outer side wall of the first clamping portion 21 to enclose the portion.

[0358] In one embodiment, please refer to Figure 21 The main housing 16 has a port at one end close to the atomizing housing 22 , and a portion of the inner wall of the main housing 16 extends into the port to form a second clamping portion 161 .

[0359] It is understandable that a portion of the inner wall of the host housing 16 extends into the port to form a protrusion, and the length of the protrusion is smaller than the extension length of the first connecting slot 21a.

[0360] Of course, the inner wall of the main body housing 16 can also be formed with a ridge, the length of which is equal to the extension length of the first connecting slot 21a. In this way, the connection stability between the main body module 10 and the atomizer module 20 can be greatly improved.

[0361] Of course, the second engaging portion 161 may also adopt other structural forms, as long as the second engaging portion 161 can pass through the opening of the first engaging portion 21 and enter the first connecting slot 21 a to be engaged with the first engaging portion 21 .

[0362] In a specific embodiment, the first clamping portion 21 is an arc-shaped plate, the first connecting slot 21 a is an arc-shaped groove, and the second clamping portion 161 is an arc-shaped protrusion corresponding to the arc-shaped groove.

[0363] In one embodiment, please refer to Figure 20 The atomizer module 20 includes a plurality of first clamping portions 21 , each of which is spaced apart on the end surface of the atomizing housing 22 , and the main body housing 16 includes a plurality of second clamping portions 161 , each of which corresponds to a first clamping portion 21 one by one.

[0364] Specifically, the number of the first clamping parts 21 is consistent with the number of the second clamping parts 161, such as 2 or 3. By providing multiple first clamping parts 21 and multiple second clamping parts 161 in a one-to-one corresponding connection, the connection between the main module 10 and the atomizer module 20 can be made more stable.

[0365] It can be understood that the first clamping portion 21 is arranged at intervals along the circumferential direction of the end surface of the atomizing shell 22, and the second clamping portion 161 is arranged at intervals along the circumferential direction of the inner wall at one end of the main body shell 16 close to the atomizing shell 22. The second clamping portion 161 is placed at the interval of the first clamping portion 21, and slides into the first connecting slot 21a from the opening of the first clamping portion 21 through relative rotation, thereby realizing the assembly between the atomizer module 20 and the main body module 10.

[0366] In one embodiment, please refer to Figure 22 and Figure 23 The first connecting slot 21a includes a connecting end 21ab and a first open end 21aa. When the second connecting portion 161 slides from the first open end 21aa to the connecting end 21ab, the two opposite sides of the second connecting portion 161 respectively engage with the walls of the first connecting slot 21a. This ensures that the atomizer module 20 and the main unit module 10 are securely connected and prevent any loosening.

[0367] Specifically, the first open end 21aa and the engaging end 21ab are located at opposite ends of the first connecting slot 21a, and the second engaging portion 161 slides from the first open end 21aa to the engaging end 21ab. When the second engaging portion 161 slides to the engaging end 21ab, it abuts against the wall of the first connecting slot 21a, thereby achieving engagement.

[0368] It should be noted that, depending on the specific shape of the second clamping portion 161 , after the second clamping portion 161 slides to the clamping end 21ab , the second clamping portion 161 may be clamped to only a portion of the wall of the first connecting clamping slot 21a .

[0369] For example, the second engaging portion 161 is a protrusion having a length smaller than that of the first connecting slot 21 a . After the second engaging portion 161 slides to the engaging end 21 ab , the second engaging portion 161 is only engaged with the slot wall of the engaging end 21 ab .

[0370] For another example, the second clamping portion 161 is a protrusion whose length is greater than or equal to that of the first connecting slot 21a. After the second clamping portion 161 slides to the clamping end 21ab, the second clamping portion 161 is clamped with the slot wall of the first connecting slot 21a over the entire length range (i.e., the slot wall from the first opening end 21aa to the clamping end 21ab).

[0371] It should be noted that the two opposing sides of the second engaging portion 161 may completely fit against the walls of the first connecting slot 21a. Alternatively, there may be a slight gap in some areas, while another area is tightly fitted. Alternatively, the two opposing sides of the second engaging portion 161 may each form an interference fit with the walls of the first connecting slot 21a.

[0372] In one embodiment, please refer to Figure 22 The cross-sectional area of ​​the first connecting slot 21a gradually decreases from the first opening end 21aa to the engaging end 21ab. This allows the atomizer module 20 and the main unit module 10 to be engaged in a gradual, tightening process, thereby ensuring efficient and convenient engagement of the first engaging portion 21 and the second engaging portion 161 and reliable functional implementation.

[0373] Specifically, the distance between the side walls of the first connecting slot 21a gradually decreases from the first open end 21aa to the engaging end 21ab. During the initial engagement of the atomizer module 20 and the main unit module 10, the gaps between the opposing sides of the second engaging portion 161 and the walls of the first connecting slot 21a are relatively large. As the second engaging portion 161 slides toward the engaging end 21ab, the gaps between the opposing sides of the second engaging portion 161 and the walls of the first connecting slot 21a gradually decrease until the opposing sides of the second engaging portion 161 are in contact with the walls of the first connecting slot 21a when the second engaging portion 161 engages the engaging end 21ab. This facilitates the sliding of the second engaging portion 161 from the first open end 21aa to the engaging end 21ab while also allowing for a gradual engagement with the first connecting slot 21a.

[0374] At the same time, since the distance between the side walls of the first connecting slot 21a gradually increases from the clamping end 21ab to the first open end 21aa, it is also convenient to remove the second clamping portion 161 from the first connecting slot 21a.

[0375] There is no limitation on the implementation method of gradually reducing the cross-sectional area of ​​the first connecting slot 21 a.

[0376] For example, the first connecting slot 21a includes an inclined slot wall 211 on the side closest to the host module 10. From the first opening end 21aa to the engaging end 21ab, the inclined slot wall 211 slopes toward the inside of the first connecting slot 21a. Thus, by tilting the slot wall on the side closest to the host module 10, the cross-sectional area of ​​the first connecting slot 21a can be gradually reduced.

[0377] It should be noted that the slot wall of the first connecting slot 21a facing away from the host module 10 can be horizontal, or can be inclined toward the first connecting slot 21a from the first opening end 21aa to the clamping end 21ab.

[0378] Specifically, the angle at which the inclined slot wall 211 is inclined toward the first connecting slot 21 a is set according to actual conditions.

[0379] Exemplarily, the angle between the inclined groove wall 211 and the end surface of the atomizing housing 22 is greater than 0° and less than or equal to 2°. For example, the angle between the inclined groove wall 211 and the end surface of the atomizing housing 22 is 1°, 1.5°, or 2°. This prevents the angle between the inclined groove wall 211 and the end surface of the atomizing housing 22 from being too large, thereby preventing the second engaging portion 161 from easily sliding out of the first connecting groove 21a.

[0380] In one embodiment, the main unit module 10 and the atomizer module 20 rotate relative to each other so that the second engaging portion 161 slides from the first opening end 21aa to the engaging end 21ab. The rotation angle of the main unit module 10 and the atomizer module 20 is greater than or equal to 5° and less than or equal to 70°. On the one hand, this can prevent the rotation angle from being too small, which would result in a smaller engagement range between the second engaging portion 161 and the first connecting slot 21a, making it easy for the main unit module 10 and the atomizer module 20 to fall off when connected. On the other hand, this can prevent the rotation angle from being too large, which would hinder the second engaging portion 161 from entering the slot through the opening of the first connecting slot 21a, making it more difficult to assemble and disassemble the main unit module 10 and the atomizer module 20.

[0381] Specifically, the rotation method of the main unit module 10 and the atomizer module 20 is not limited, as long as the second engaging portion 161 can slide from the first opening end 21aa to the engaging end 21ab to achieve engaging.

[0382] Depending on the actual situation, the host module 10 can remain stationary and the atomizer module 20 can rotate relative to the host module 10, or the atomizer module 20 can remain stationary and the host module 10 can rotate relative to the atomizer module 20, or the atomizer module 20 and the host module 10 can rotate at the same time.

[0383] In one embodiment, please refer to Figure 23One of the groove wall of the first connecting groove 21a and the outer surface of the second engaging portion 161 forms a limiting protrusion 212, and the other forms a limiting groove 21b. When the second engaging portion 161 is located at the engaging end 21ab, the limiting protrusion 212 is located within the limiting groove 21b. Therefore, when the second engaging portion 161 is located at the engaging end 21ab, placing the limiting protrusion 212 within the limiting groove 21b can make the connection between the atomizer module 20 and the main unit module 10 more tightly.

[0384] Specifically, the limiting protrusion 212 may be formed on the wall of the first connecting slot 21 a , and the limiting groove 21 b may be formed on the outer surface of the second clamping portion 161 .

[0385] Alternatively, the groove wall of the first connecting groove 21 a may form a limiting groove 21 b , and the outer surface of the second clamping portion 161 may form a limiting protrusion 212 .

[0386] The number of the limiting protrusions 212 and the limiting grooves 21 b is not limited, as long as the second clamping portion 161 is located at the clamping end 21 ab and the limiting protrusion 212 is located in the limiting groove 21 b.

[0387] For example, the number of the limiting protrusions 212 is one or more, and the multiple limiting protrusions 212 are distributed at intervals. The number of the limiting grooves 21b is also one or more, and the multiple limiting grooves 21b are distributed at intervals.

[0388] In one embodiment, please refer to Figure 22 The atomizer module 20 has a second air inlet 20a. When the main unit module 10 and the atomizer module 20 are connected, the air compressor 11 communicates with the second air inlet 20a. On the one hand, after the main unit module 10 and the atomizer module 20 are snap-fitted together, the air compressor 11 communicates with the second air inlet 20a, which ensures a good airtight seal for the electronic atomization device. On the other hand, the air compressor 11 supplies air to the atomizer module 20, atomizing the atomized liquid within the atomizer module 20 and achieving the atomization function.

[0389] In one embodiment, please refer to Figure 1 、 Figure 28 、 Figure 29 and Figure 30 The atomizer module 20 includes an atomizing body 201 , a dust cover 28 and a fourth sealing member 29 .

[0390] The atomizing body 201 includes an atomizing housing 22 and a nozzle 23. The dust cover 28 has an installation space 28a. One end of the installation space 28a is open to form an installation inlet 12b. The dust cover 28 is detachably connected to the atomizing housing 22 so that the nozzle 23 can be detachably installed in the installation space 28a through the installation inlet 12b.

[0391] The fourth sealing member 29 is located in the installation space 28a and is connected to the dust cover 28. The dust cover 28 moves relative to the atomizing housing 22 to drive the fourth sealing member 29 to switch between blocking the mist outlet 23a and avoiding the mist outlet 23a.

[0392] Thus, on the one hand, by blocking the nozzle 23 of the atomizer module 20 through the fourth sealing member 29, the atomized liquid can be effectively prevented from leaking into the air from the mist outlet 23a, and the atomized liquid can be prevented from crystallizing due to exposure, thereby clogging the nozzle 23. This ensures that the atomized liquid 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 22a through the mist outlet 23a, thereby contaminating the atomized liquid. On the other hand, by connecting the fourth sealing member 29 to the dust cover 28, the fourth sealing member 29 can move synchronously with the movement of the dust cover 28 relative to the atomizing housing 22, thereby more effectively blocking or avoiding the mist outlet 23a.

[0393] Specifically, the nozzle 23 enters the installation space 28a of the dust cover 28 through the installation inlet 12b. When the dust cover 28 is connected to the atomizing housing 22, the fourth sealing member 29 in the dust cover 28 blocks the mist outlet 23a of the nozzle 23 of the atomizing body 201.

[0394] The dust cover 28 is connected to the atomizing housing 22 in any manner. For example, the dust cover 28 is connected to the atomizing housing 22 by a buckle. In another example, the dust cover 28 is connected to the atomizing housing 22 by a thread.

[0395] The fourth sealing member 29 is not limited to a position within the installation space 28a of the dust cover 28. For example, the fourth sealing member 29 is located on a side wall of the dust cover 28. In another example, the fourth sealing member 29 is located on the inner wall of the dust cover 28 facing away from the installation inlet 12b.

[0396] The connection method between the fourth sealing member 29 and the dust cover 28 is not limited.

[0397] For example, the fourth sealing member 29 is detachably engaged in the installation space 28 a of the dust cover 28 .

[0398] For another example, the fourth sealing member 29 is glued into the installation space 28 a of the dust cover 28 to be fixedly connected to the dust cover 28 .

[0399] The material type of the fourth sealing member 29 is not limited, as long as it can block the mist outlet 23a when the dust cover 28 is connected to the atomizing housing 22. For example, the fourth sealing member 29 is an elastic member.

[0400] When the user installs the dust cover 28 on the atomizer housing 22, the fourth sealing member 29 can block the mist outlet 23a of the nozzle 23. When the user detaches the dust cover 28 from the atomizer housing 22, the fourth sealing member 29 can separate from the nozzle 23, thereby avoiding the mist outlet 23a.

[0401] In one embodiment, please refer to Figure 28 The dust cover 28 includes a dust cover wall 281 located on the side of the installation space 28a facing away from the installation inlet 12b. A portion of the inner wall of the dust cover wall 281 extends toward the installation inlet 12b to enclose a receiving space 41b. The fourth sealing member 29 is disposed within the receiving space 41b. Thus, installing the fourth sealing member 29 within the receiving space 41b provides stability for the fourth sealing member 29 and allows the fourth sealing member 29 to accurately seal the mist outlet 23a of the nozzle 23 when the dust cover 28 is connected to the atomizer housing 22.

[0402] Specifically, the dust cover wall 281 refers to an area on the dust cover 28 that is opposite to the installation entrance 12 b.

[0403] Part of the wall surface of the dust cover wall 281 located in the accommodating cavity 16 a extends toward the installation entrance 12 b to form an accommodating space 41 b for accommodating the fourth sealing member 29 .

[0404] It is understandable that the shape of the area of ​​the inner wall of the dust cover wall 281 extending toward the installation entrance 12b is not limited, as long as it can form an accommodating space 41b and cooperate with the fourth seal 29 so that the fourth seal 29 is installed in the accommodating space 41b.

[0405] For example, the annular region of the inner wall surface of the dust cover wall 281 extends toward the installation entrance 12 b to form an annular accommodating space 41 b.

[0406] For another example, a plurality of regions of the inner wall surface of the dust cover wall 281 extend toward the installation entrance 12 b at intervals to form the accommodation space 41 b.

[0407] The manner in which the fourth sealing member 29 is disposed in the accommodation space 41 b is not limited.

[0408] For example, a connecting buckle 284 that cooperates with the fourth sealing member 29 is provided on the side wall surface 283 of the accommodating space 41 b , and the fourth sealing member 29 and the connecting buckle 284 cooperate with each other to be installed in the accommodating space 41 b .

[0409] For another example, the fourth sealing member 29 is installed in the accommodating space 41 b by interference fit with the side wall surface 283 of the accommodating space 41 b.

[0410] In one embodiment, please refer to Figure 28 The inner wall surface of the dust cover wall 281 includes a mounting wall surface and a side wall surface 283 located within the accommodating space 41b. The mounting wall surface is located on the side of the accommodating space 41b facing away from the mounting inlet 12b. A portion of the mounting wall surface protrudes toward the nozzle 23 to form a protrusion 282. The protrusion 282 and at least a portion of the side wall surface 283 are separated to form a receiving groove 281a. The end of the fourth sealing member 29 facing away from the nozzle 23 is retained in the receiving groove 281a for detachable connection with the dust cover 28. Thus, the engagement of the fourth sealing member 29 with the receiving groove 281a ensures a more secure connection between the fourth sealing member 29 and the dust cover 28.

[0411] It can be understood that since part of the inner wall surface of the dust cover wall 281 extends to form the accommodating space 41b, the accommodating space 41b has an installation wall surface and a side wall surface 283, that is, the installation wall surface and the side wall surface 283 are both part of the inner wall surface.

[0412] Specifically, the installation wall is located on a side of the accommodating space 41 b away from the installation entrance 12 b , that is, the installation wall is arranged opposite to the installation entrance 12 b .

[0413] The mounting wall surface can be formed by protruding a central region to form a protrusion 282, whereby the outer periphery of the protrusion 282 is spaced apart from the side wall surface 283, thereby forming the receiving groove 281a. Of course, the protrusion 282 can also be formed by one side being in contact with the side wall surface 283 and the other side being spaced apart from the side wall surface 283, thereby forming the receiving groove 281a.

[0414] The shape and size of the fourth sealing member 29 are set according to the shape and size of the receiving groove 281a to ensure that the fourth sealing member 29 can be well fixed in the receiving groove 281a and the atomizer module 20 will not fall out of the receiving groove 281a during use.

[0415] The specific manner in which the fourth sealing member 29 is clamped in the receiving groove 281 a is not limited.

[0416] For example, the fourth sealing member 29 is provided with a buckle or a protrusion, so that it can be snapped into the receiving groove 281a, thereby achieving fixation of the fourth sealing member 29 and the receiving groove 281a.

[0417] For another example, when the fourth sealing member 29 is made of an elastic material, the fourth sealing member 29 can be pressed into the receiving groove 281 a by pressure, thereby achieving fixation between the fourth sealing member 29 and the receiving groove 281 a.

[0418] In one embodiment, please refer to Figure 28The outer circumferential surface of the protrusion 282 is spaced apart from the sidewall surface 283. The receiving groove 281a is an annular groove. The fourth seal 29 has a receiving cavity 16a. The end of the receiving cavity 16a facing away from the nozzle 23 is open, forming a second open end 291 of the fourth seal 29. The end of the receiving cavity 16a near the nozzle 23 is sealed, forming a sealed end 292 of the fourth seal 29. The second open end 291 is retained in the receiving groove 281a. Thus, by retaining the second open end 291 of the fourth seal 29 in the receiving groove 281a, the connection between the fourth seal 29 and the dust cover 28 is more secure.

[0419] Specifically, the fourth sealing member 29 is connected to the accommodating groove 281 a through the second open end 291 , and blocks the nozzle 23 through the sealing end 292 when the dust cover 28 is connected to the atomizing housing 22 .

[0420] The shape of the protrusion 282 is not limited, as long as the outer circumferential surface of the protrusion 282 can cooperate with the side wall surface 283 to form the receiving groove 281a. For example, the protrusion 282 is cylindrical. In another example, the protrusion 282 is conical and cooperates with the side wall surface 283 to form annular receiving grooves 281a of varying diameters, thereby facilitating the guidance or positioning of the fourth sealing member 29.

[0421] The second opening end 291 is locked in the receiving groove 281 a in any manner.

[0422] For example, the second opening end 291 is designed with a specific shape, such as a flange or an edge, and can be directly inserted into the receiving groove 281a, relying on friction or shape matching to maintain the engagement with the receiving groove 281a.

[0423] For another example, the second opening end 291 and the receiving groove 281 a are locked with the receiving groove 281 a through interference fit.

[0424] In one embodiment, the fourth sealing member 29 is an elastomer. When the dust cover 28 is installed on the atomizing housing 22, the fourth sealing member 29 abuts against the nozzle 23, thereby elastically deforming and sealing the mist outlet 23a. This allows the fourth sealing member 29 to fit more closely with the mist outlet 23a, forming a good seal.

[0425] Specifically, the material type of the fourth sealing member 29 is not limited as long as it can produce elastic deformation.

[0426] For example, the fourth seal 29 can be made of one of silicone, air-rubber, and fluorosilicone. This allows the fourth seal 29 to provide a better seal against the mist outlet 23a. Furthermore, the fourth seal 29 can have better corrosion resistance. When the fourth seal 29 seals the mist outlet 23a, it will not be damaged by corrosion when it comes into contact with the atomized liquid in the liquid storage chamber 22a.

[0427] In one embodiment, the end surface of the fourth sealing member 29 near the mist outlet 23a is one of a flat surface and an arc surface. This can ensure that the contact area between the fourth sealing member 29 and the mist outlet 23a is maximized, thereby improving the sealing effect.

[0428] In one embodiment, the hardness of the fourth sealing member 29 is greater than or equal to 40 Shore A and less than or equal to 80 Shore A. For example, the hardness of the fourth sealing member 29 is 40 Shore A, 60 Shore A, or 80 Shore A. Thus, employing a hardness within the above range can provide the fourth sealing member 29 with good elasticity and structural strength, allowing it to adapt to the irregular surface and slight dimensional variations of the mist outlet 23a, thereby improving the sealing effect.

[0429] In one embodiment, please refer to Figure 28 and Figure 30 One of the atomizing housing 22 and the dust cover 28 has a second connecting slot 22f, and the other has a connecting buckle 284 that engages with the second connecting slot 22f. Thus, the connection between the atomizing housing 22 and the dust cover 28 is stabilized by the engagement of the connecting buckle 284 with the second connecting slot 22f.

[0430] Specifically, the atomizing housing 22 may have a second connecting slot 22f, and the dust cover 28 may have a connecting buckle 284. Depending on the actual situation, the atomizing housing 22 may have a connecting buckle 284, and the dust cover 28 may have a second connecting slot 22f.

[0431] It is understandable that the shape and size of the connecting buckle 284 match the second connecting slot 22f to achieve a snap fit.

[0432] The snap-fitting between the connecting buckle 284 and the second connecting slot 22 f is detachable, allowing the user to conveniently install and remove the dust cover 28 .

[0433] Through the precise cooperation between the second connecting groove 22f and the connecting buckle 284, the fourth sealing member 29 can accurately block the mist outlet 23a of the nozzle 23, thereby improving the sealing effect.

[0434] In one embodiment, please refer to Figure 30 At least a portion of the end of the atomizing housing 22 facing away from the nozzle 23 is recessed to form a second connecting slot 22f. At the installation inlet 12b, at least a portion of the inner wall of the dust cover 28 extends into the installation inlet 12b to form a connecting buckle 284. Thus, the design of the second connecting slot 22f and the connecting buckle 284 ensures a stable connection, maintaining a secure connection between the atomizing housing 22 and the dust cover 28 even under vibration or impact.

[0435] It is understandable that at least a portion of the inner wall of the dust cover 28 extends into the installation entrance 12 b to form a connecting buckle 284 . The connecting buckle 284 may be a convex block or a convex strip.

[0436] There may be a plurality of protrusions, which are arranged at intervals along the inner wall of the dust cover 28 in the circumferential direction.

[0437] The convex strips extend along the circumferential direction of the inner wall of the dust cover 28 , and the length of the convex strips is less than or equal to the circumferential length of the inner wall of the dust cover 28 .

[0438] The end of the atomizing housing 22 facing away from the nozzle 23 may be partially recessed corresponding to the protrusion or ridge to form a second connecting slot 22f. The length of the second connecting slot 22f is greater than or equal to the length of the protrusion or ridge. Alternatively, the entire area may be recessed to form the second connecting slot 22f.

[0439] For example, the atomizer housing 22 has a plurality of second connecting slots 22f, each of which is spaced apart along the circumference of the atomizer housing 22. The dust cover 28 includes a plurality of spaced connecting clips 284, each of which is engaged with a second connecting slot 22f in a one-to-one correspondence. Thus, the engagement of the plurality of slots and clips provides multiple fixing points, thereby increasing the stability of the connection between the dust cover 28 and the atomizer housing 22 and reducing the risk of the dust cover 28 falling off due to vibration or accidental collision.

[0440] In one embodiment, please refer to Figure 24 and Figure 25 The main housing 16 has a receiving cavity 16 a , and a portion of the main housing 16 is opened to form a mounting opening 16 c , which is communicated with the receiving cavity 16 a .

[0441] The air compressor 11 has a first air inlet 11b and an air outlet 11a. The area of ​​the air compressor 11 with the first air inlet 11b is located in the accommodating chamber 16a, communicating with the outside through a gap in the main body housing 16. The area of ​​the air compressor 11 with the air outlet 11a is located in the mounting opening 16c. One end of the air passage 22b is connected to the air outlet 11a, and the nozzle 23 is connected to the other end of the air passage 22b and the liquid storage chamber 22a.

[0442] Thus, the first air inlet 11b can be built into the accommodating cavity 16a to avoid direct exposure of the first air inlet 11b to the outside of the main housing 16, thereby reducing the risk of external liquid directly entering the interior of the air compressor 11 through the first air inlet 11b, thereby preventing the interior of the air compressor 11 from being contaminated or damaged. At the same time, the first air inlet 11b built into the accommodating cavity 16a can pass through the gap of the main housing 16 to communicate with the outside world, so that external gas can enter the accommodating cavity 16a through the gap of the main housing 16, and then can supply air to the air compressor 11 through the first air inlet 11b. Thus, the risk of liquid entering the air compressor 11 can be reduced while the normal air intake of the air compressor 11 will not be affected.

[0443] Specifically, the first air inlet 11 b of the air compressor 11 is an air flow inlet for external air to enter the air compressor 11 .

[0444] The air outlet 11 a of the air compressor 11 is an airflow outlet for outputting high-speed airflow.

[0445] The area of ​​the air compressor 11 having the first air inlet 11b is located within the accommodating cavity 16a. In other words, the first air inlet 11b of the air compressor 11 is not located externally on the main body housing 16, but is instead internally located within the accommodating cavity 16a. By locating the first air inlet 11b within the accommodating cavity 16a, rather than extending to the outer surface of the main body housing 16 or directly to the exterior of the main body housing 16, the risk of external liquids (such as the atomized liquid in the electronic atomization device) entering the interior of the air compressor 11 through the first air inlet 11b can be greatly reduced.

[0446] It is understandable that the first air inlet 11 b of the air compressor 11 still needs to be connected to the outside world so that the outside air flow can enter the air compressor 11 through the first air inlet 11 b.

[0447] The first air inlet 11 b of the air compressor 11 is connected to the outside through a gap in the main body housing 16 .

[0448] It should be noted that the housing 16a of the main unit housing 16 is not a completely enclosed cavity. Small gaps exist within the main unit housing 16 itself. For example, the main unit housing 16 includes multiple walls, each of which encloses the housing 16a. At the junctions between the walls, portions of adjacent walls are separated to create gaps for external airflow into the housing 16a.

[0449] The number of gaps on the main housing 16 can be set according to actual conditions.

[0450] For example, the main housing 16 has a plurality of gaps, and the sum of the areas of the gaps is greater than or equal to 1.5 mm. 2Thus, it is possible to ensure that external air enters the accommodating chamber 16a through the gap and then enters the air compressor 11 through the first air inlet 11b.

[0451] The mounting port 16c of the main housing 16 is a connecting port for the air outlet 11a to extend out of the accommodating cavity 16a. Thus, by forming the mounting port 16c, the air outlet 11a of the air compressor 11 can be placed outside the accommodating cavity 16a, thereby facilitating the high-speed airflow provided by the air compressor 11 to flow out of the main housing 16 through the air outlet 11a, and then facilitate the nozzle 23 to receive it.

[0452] At the same time, it should be noted that since the air outlet 11a is used to allow air to flow out of the air compressor 11, and the first air inlet 11b is used to allow air to flow into the air compressor 11, the risk of external liquid entering the air compressor 11 through the air outlet 11a is lower than that of the first air inlet 11b. Therefore, compared with the internalization of the air outlet 11a, the internalization of the first air inlet 11b can better reduce the risk of liquid entering the air compressor 11.

[0453] The specific sizes of the first air inlet 11b and the air outlet 11a can be set according to actual conditions.

[0454] For example, the inner diameter of the first air inlet 11b 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 first air inlet 11b is 0.7 mm, 1 mm, or 1.5 mm. The first air inlet 11b having a size within the above range can enable the air compressor 11 to have a better air intake effect.

[0455] For another example, the inner diameter of the air outlet 11a 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 11a is 0.7 mm, 1 mm, or 1.5 mm. The air outlet 11a having a size within the above range can enable the air compressor 11 to have a better air outlet effect.

[0456] Furthermore, the specific shapes of the first air inlet 11b and the air outlet 11a can also be set according to actual conditions.

[0457] For example, the first air inlet 11 b is a circular hole, a square hole, or a rectangular hole.

[0458] For another example, the air outlet 11a is a circular hole, a square hole, or a rectangular hole.

[0459] In one embodiment, please refer to Figure 25 The main housing 16 includes a connecting end wall 162 having the mounting port 16c. The opening of the first air inlet 11b faces the connecting end wall 162. The first air inlet 11b is offset from the mounting port 16c and spaced apart from the connecting end wall 162.

[0460] Specifically, a portion of the connecting end wall 162 at the end of the main housing 16 is opened to form a mounting opening 16c. The air outlet 11a extends to the mounting opening 16c, thereby facilitating the air compressor 11 to supply air to the nozzle 23 from the mounting opening 16c.

[0461] The first air inlet 11b is built into the accommodating cavity 16a, and the opening of the first air inlet 11b is not directly facing the outside of the main housing 16, but facing the connecting end wall 162. In addition, the first air inlet 11b and the mounting port 16c are staggered, that is, the first air inlet 11b and the mounting port 16c are staggered. As a result, the connecting end wall 162 can form a certain shielding for the first air inlet 11b, so as to reduce the risk of external liquid directly entering the interior of the air compressor 11 through the first air inlet 11b. At the same time, since the first air inlet 11b and the connecting end wall 162 are spaced apart, it is possible to avoid the connecting end wall 162 completely blocking the first air inlet 11b, thereby preventing the problem of poor air intake at the first air inlet 11b.

[0462] It should be noted that the specific formation position of the gap in the main body housing 16 is not limited.

[0463] For example, the gap in the main housing 16 is arranged to avoid the connection end wall 162. Thus, the gap in the main housing 16 can be arranged as much as possible on the peripheral side of the main housing 16, or at the end of the main housing 16 opposite the connection end wall 162. This can further reduce the risk of external liquid entering the air compressor 11 through the first air inlet 11b.

[0464] In one embodiment, please refer to Figure 26 The air compressor 11 has an air compressor end face 111 at one end close to the mounting port 16c. The air compressor end face 111 has an air inlet area and an air outlet area. The first air inlet 11b is located in the air inlet area, and the air outlet 11a is located in the air outlet area. The air outlet area protrudes relative to the air inlet area so that the air outlet 11a extends into the mounting port 16c.

[0465] Specifically, the first air inlet 11b and the air outlet 11a are both arranged on the end face of the air compressor 11 close to the installation port 16c, thereby allowing the airflow entering the air compressor 11 from the first air inlet 11b to flow out from the air outlet 11a more conveniently.

[0466] The air inlet region is a region on the air compressor end surface 111 for forming the first air inlet 11 b , and the air outlet region is a region on the air compressor end surface 111 for forming the air outlet 11 a .

[0467] By making the air outlet area protrude, the air outlet 11 a can be extended into the installation opening 16 c , thereby facilitating air outlet 11 a .

[0468] 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 first air inlet 11 b to be built into the accommodating cavity 16 a.

[0469] In one embodiment, please refer to Figure 26 and Figure 27 The air inlet area is recessed to form a recessed space 111 a , and the hole wall of the first air inlet 11 b extends into the recessed space 111 a so as to be spaced apart from the connecting end wall 162 .

[0470] Specifically, the air intake area is recessed relative to other areas of the air compressor end face 111, thereby forming a recessed space 111a. By forming the recessed space 111a and setting the hole wall forming the first air inlet 11b within the recessed space 111a, it can be ensured that the hole wall of the first air inlet 11b and the connecting end wall 162 are spaced apart from each other, thereby avoiding the connecting end wall 162 and the first air inlet 11b from fitting together and blocking the first air inlet 11b, thereby ensuring a better air intake effect.

[0471] In one embodiment, at least a portion of the outer circumference of the air compressor 11 is spaced apart from the main housing 16 to form a separation space, and the recessed space 111a extends along one side of the circumference to the outer circumference of the air compressor 11 to communicate with the separation space.

[0472] Specifically, the outer peripheral surface of the air compressor 11 can be partially spaced from the main housing 16, and a space is formed at the space. Of course, the outer peripheral surface of the air compressor 11 can be entirely spaced from the main housing 16, and a space is formed at the space.

[0473] Moreover, by opening one side of the recessed space 111a to communicate with the partition space, it is convenient for external airflow to enter the accommodating cavity 16a through the gap of the main housing 16, pass through the partition space and the recessed space 111a, and then enter the air compressor 11 from the first air inlet 11b, thereby providing an air intake effect for the air compressor 11.

[0474] Another embodiment of the present application provides a liquid injection device, see Figure 31 The liquid injection device includes a liquid injection shell 30 and a liquid injection component 40.

[0475] The liquid injection housing 30 has a liquid storage space 30 a and a liquid supply port 30 b , and the liquid storage space 30 a is communicated with the liquid supply port 30 b .

[0476] See also Figure 32The liquid injection assembly 40 includes a liquid injection head 41 and a second one-way valve 42. The liquid injection head 41 has a second liquid injection port 41a, and the liquid injection head 41 is covered on one end of the liquid injection shell 30 having a liquid supply port 30b, so that a liquid outlet path is formed between the liquid supply port 30b and the second liquid injection port 41a. The second one-way valve 42 is arranged between the liquid injection head 41 and the liquid supply port 30b to switch between opening and closing the liquid outlet path.

[0477] Thus, by providing the second one-way valve 42, during the process of the liquid injection device injecting liquid into the electronic atomizer device, the second one-way valve 42 can open the liquid outlet path, allowing the atomized liquid in the liquid storage space 30a to flow out along the liquid outlet path to replenish the atomized liquid in the electronic atomizer device. At the same time, after the liquid injection is completed, the second one-way valve 42 can block the liquid outlet path to prevent the atomized liquid in the liquid storage space 30a from flowing out of the liquid supply port 30b and the second liquid injection port 41a, thereby reducing the risk of leakage and preventing the atomized liquid in the liquid storage space 30a from being exposed, thereby preventing the problem of solution waste and contamination.

[0478] Specifically, the liquid injection device is used to replenish the atomizing liquid into the electronic atomizing device described in any embodiment of the present application.

[0479] The liquid storage space 30a is a liquid storage space 30a in the liquid injection device for storing atomized liquid.

[0480] The liquid supply port 30b is a liquid outlet for the atomized liquid in the liquid storage space 30a to flow out.

[0481] The second liquid injection port 41a is used to allow the atomized liquid from the liquid outlet to flow out of the liquid injection device so as to be replenished into the electronic atomization device.

[0482] The injection head 41 is covered at the liquid supply port 30b, which can facilitate the atomized liquid in the liquid storage space 30a to flow out of the injection device through the liquid supply port 30b and the second liquid injection port 41a. Thus, a liquid outlet path for the atomized liquid to flow from the liquid supply port 30b to the second liquid injection port 41a can be formed.

[0483] The second one-way valve 42 is disposed between the injection head 41 and the liquid supply port 30b. In practice, the second one-way valve 42 is located on the liquid outlet path. Opening the second one-way valve 42 enables communication between the liquid supply port 30b and the second liquid injection port 41a, allowing atomized liquid to flow from the liquid supply port 30b to the second liquid injection port 41a and out of the injection device from the second liquid injection port 41a. Closing the second one-way valve 42 separates the injection head 41 and the liquid supply port 30b, preventing the atomized liquid from flowing from the liquid supply port 30b to the second liquid injection port 41a. Thus, opening and closing the second one-way valve 42 enables switching between opening and closing the liquid outlet path.

[0484] It is understandable that when the second one-way valve 42 opens the liquid outlet path, the second one-way valve 42 can only allow the atomized liquid to flow from the liquid supply port 30b to the second liquid injection port 41a in one direction, but cannot allow the atomized liquid to flow from the second liquid injection port 41a to the liquid supply port 30b.

[0485] The specific material type of the second one-way valve 42 is not limited. For example, the material of the second one-way valve 42 is one of silicone and rubber. In this way, the second one-way valve 42 can have a good sealing effect and elastic deformation ability.

[0486] For another example, the material hardness of the second one-way valve 42 is greater than or equal to 40 Shore A and less than or equal to 80 Shore A. For example, 40 Shore A, 60 Shore A, and 80 Shore A. Therefore, the use of the above-mentioned material hardness for the second one-way valve 42 can provide the second one-way valve 42 with greater structural strength and improved wear resistance.

[0487] The liquid injection device of the present application can greatly reduce the risk of liquid leakage of the liquid injection device by setting a second one-way valve 42. At the same time, the second one-way valve 42 will not have a significant impact on the liquid injection effect of the liquid injection device. Its simple structure makes the cost of the liquid injection device low.

[0488] In one embodiment, please refer to Figure 32 、 Figure 33 and Figure 34 The second one-way valve 42 is arranged at the liquid supply port 30b. The second one-way valve 42 has a valve port 42a which is respectively connected to the liquid supply port 30b and the second liquid injection port 41a. The valve port 42a is located on the liquid outlet path. Under the action of external force, the second one-way valve 42 switches between opening and closing the valve port 42a to switch between opening and closing the liquid outlet path.

[0489] Specifically, the second one-way valve 42 opens the valve port 42a, thereby connecting the liquid supply port 30b with the second liquid injection port 41a, thereby opening the liquid outlet path. At the same time, the second one-way valve 42 closes the valve port 42a, thereby separating the liquid supply port 30b from the second liquid injection port 41a, thereby blocking the liquid outlet path.

[0490] Thus, the valve port 42a of the second one-way valve 42 can be opened and closed, thereby improving the anti-leakage effect of the liquid injection device and simultaneously not affecting the liquid injection process of the liquid injection device.

[0491] In one embodiment, please refer to Figure 34The second one-way valve 42 includes a second valve body 421 and a valve nozzle 422. The second valve body 421 covers the liquid supply port 30b, and the valve nozzle 422 is located at the end of the second valve body 421 near the second liquid inlet 41a. The valve nozzle 422 includes a first abutment portion 423 and a second abutment portion 424 provided on the second valve body 421. At the end of the valve nozzle 422 near the second liquid inlet 41a, at least portions of the first abutment portion 423 and the second abutment portion 424 are disconnected and abutted against each other, forming a closed valve port 42a. When the liquid injection housing 30 is squeezed by an external force, the pressure difference between the inside and outside of the liquid storage space 30a causes the disconnection between the first abutment portion 423 and the second abutment portion 424 to separate, thereby opening the valve port 42a. This allows the second one-way valve 42 to both open and close the liquid outlet path while significantly simplifying its structure.

[0492] Specifically, the valve nozzle 422 has a valve opening 42a. At the valve opening 42a, the first abutment portion 423 and the second abutment portion 424 are not continuously connected, but rather disconnected. Furthermore, when the user is not squeezing the liquid injection housing 30, the first abutment portion 423 and the second abutment portion 424 abut against each other, thereby closing the valve opening 42a and blocking the liquid outflow path.

[0493] When a user applies pressure to the liquid injection housing 30, the liquid storage space 30a of the liquid injection housing 30 is compressed, and the pressure inside the liquid storage space 30a becomes greater than the pressure outside the liquid storage space 30a, causing the first and second fitting portions 423 and 424 to separate from each other, and the valve port 42a switches from a closed state to an open state. The atomized liquid in the liquid storage space 30a can also flow from the liquid storage space 30a to the second liquid injection port 41a due to the pressure difference, and then out of the liquid injection device.

[0494] It should be noted that the specific structure of the second one-way valve 42 can be set according to actual conditions.

[0495] For example, see Figure 34 The cross-sectional dimensions of the second valve body 421 gradually decrease from the end facing away from the second liquid injection port 41a to the end closer to the second liquid injection port 41a. In other words, the outer dimensions of the second valve body 421 gradually decrease as it approaches the second liquid injection port 41a. This allows the space within the second valve body 421 for the atomized liquid to flow to gradually decrease, thereby directing the atomized liquid toward the second liquid injection port 41a, thereby facilitating its outflow from the second liquid injection port 41a.

[0496] For another example, the cross-sectional dimensions of the valve nozzle 422 gradually decrease from the end facing away from the second liquid injection port 41a to the end closer to the second liquid injection port 41a. Thus, the outer dimensions of the valve nozzle 422 can be gradually reduced toward the second liquid injection port 41a, further directing the atomized liquid toward the second liquid injection port 41a.

[0497] In one embodiment, please refer to Figure 34 The first fitting portion 423 and the second fitting portion 424 are both inclined surfaces, and from the end away from the second liquid injection port 41a to the end close to the second liquid injection port 41a, the first fitting portion 423 and the second fitting portion 424 are inclined in a direction of approaching each other.

[0498] Specifically, by configuring the first and second fitting portions 423, 424 as inclined surfaces, the distance between the first and second fitting portions 423, 424 can be gradually reduced until they abut against each other, from the end facing away from the second liquid injection port 41a to the end facing the second liquid injection port 41a. Thus, after the external force is removed, the valve ports 42a can be brought into contact with each other, thereby closing the valve ports 42a. Furthermore, because the first and second fitting portions 423, 424 are inclined surfaces that are inclined toward each other, they can guide the atomized liquid toward the second liquid injection port 41a.

[0499] In one embodiment, please refer to Figure 34 The second valve body 421 has a ventilation hole 421a that communicates with the liquid storage space 30a and the outside world, respectively. This creates a ventilation path between the outside world and the liquid storage space 30a, passing through the ventilation hole 421a. This facilitates external airflow into the liquid storage space 30a through the ventilation hole 421a, replenishing the liquid storage space 30a with gas, thereby facilitating subsequent liquid injection by the injection device.

[0500] Specifically, the ventilation path is an airflow path for external air to flow into the liquid storage space 30a.

[0501] When a user applies a squeeze force to the liquid injection housing 30, the second one-way valve 42 opens the liquid outlet path, allowing the atomized liquid in the liquid storage space 30a to flow from the liquid storage space 30a to the second liquid injection port 41a and out of the liquid injection device. At this time, because the valve port 42a is located at the end of the valve nozzle 422 near the second liquid injection port 41a, and the ventilation hole 421a is located on the second valve body 421, the atomized liquid will pass through the second one-way valve 42 from the location where it is most likely to flow out, that is, the atomized liquid will pass more through the valve port 42a.

[0502] Therefore, most of the atomized liquid can flow through the valve port 42a to the second liquid injection port 41a, and only a small portion of the atomized liquid can flow through the ventilation hole 421a to the second liquid injection port 41a. Alternatively, all of the atomized liquid can flow through the valve port 42a to the second liquid injection port 41a, and no atomized liquid can flow through the ventilation hole 421a to the second liquid injection port 41a.

[0503] When the user cancels the squeezing force applied to the liquid injection shell 30, the liquid injection shell 30 returns to its initial state through elasticity, and gas needs to be replenished from the outside to enter the liquid storage space 30a. However, since the squeezing force applied to the liquid injection shell 30 is canceled, the separation between the first fitting portion 423 and the second fitting portion 424 is reclosed, and external gas cannot be replenished into the liquid storage space 30a through the valve port 42a. Therefore, by providing the ventilation hole 421a, external gas can flow along the ventilation path, thereby entering the liquid storage space 30a through the ventilation hole 421a, so that the liquid injection shell 30 can be restored to its initial state. As a result, it is convenient for the user to squeeze the liquid injection shell 30 again, and the process of re-filling the liquid injection device can be realized.

[0504] In one embodiment, please refer to Figure 31 and Figure 32 The side wall of the liquid supply port 30b protrudes outward from the liquid storage space 30a to form a connecting boss 31. The liquid injection head 41 has an accommodating space 41b connected to the second liquid injection port 41a. The second one-way valve 42 is arranged in the accommodating space 41b. The liquid injection head 41 cover is arranged on the connecting boss 31, and the connecting boss 31 extends into the accommodating space 41b so that the second one-way valve 42 is squeezed and fixed at the liquid supply port 30b.

[0505] Specifically, by forming the connecting boss 31, the liquid injection head 41 and the second one-way valve 42 can be easily connected to the liquid injection housing 30. By covering the liquid injection head 41 on the connecting boss 31, the second one-way valve 42 can be pressed against the liquid supply port 30b, thereby improving the installation stability of the second one-way valve 42 and reducing the risk of leakage of the atomized liquid from the liquid supply port 30b.

[0506] It should be noted that the liquid injection head 41 and the connecting boss 31 can be connected in a non-detachable manner. Of course, a detachable connection can also be adopted, thereby facilitating the disassembly of the liquid injection head 41 and the connecting boss 31 so as to facilitate the maintenance and replacement of the second one-way valve 42.

[0507] For example, an internal thread is formed on the inner wall of the accommodating space 41 b , and an external thread is formed on the outer wall of the connecting boss 31 , thereby enabling the liquid injection head 41 and the connecting boss 31 to be threadedly connected.

[0508] Of course, the liquid injection head 41 and the connecting boss 31 can also be connected in a detachable manner by snapping, plugging or other detachable connection methods.

[0509] In one embodiment, please refer to Figure 33 and Figure 34 The connecting boss 31 includes a connecting end surface 31a close to the second liquid injection port 41a. The second one-way valve 42 has a flange 425 formed on one end close to the connecting boss 31. The flange 425 is in contact with the connecting end surface 31a.

[0510] Specifically, the end surface of the second one-way valve 42 near the connecting boss 31 extends radially outward to form a flange 425 that is folded relative to the outer peripheral surface of the second one-way valve 42. The flange 425 facilitates the fit of the second one-way valve 42 against the connecting end surface 31a, making the second one-way valve 42 more stable under the pressure of the connecting boss 31 and the liquid injection head 41.

[0511] In one embodiment, please refer to Figure 33 The injection head 41 includes an injection body 411 and a sealing cap 412. The injection body 411 has a second injection port 41a, and the sealing cap 412 is detachably mounted on the second injection port 41a. Thus, the sealing cap 412 seals the second injection port 41a, further reducing the risk of leakage from the injection device and improving the sealing performance of the injection device.

[0512] In one embodiment, the second liquid injection port 41a of the liquid injection device is connected to the liquid inlet, and the user can squeeze the liquid injection shell 30 to allow the atomized liquid in the liquid injection device to pass through the second liquid injection port 41a and the liquid inlet, and then be replenished into the liquid storage space 30a of the electronic atomization device, thereby achieving liquid replenishment in the electronic atomization device.

[0513] An embodiment of the present application provides an electronic atomization device, see Figure 1 and Figure 35 The electronic atomization device includes a host module 10 and an atomizer module 20.

[0514] The host module 10 includes a power supply assembly 13 and an air compressor 11 , and the power supply assembly 13 and the air compressor 11 are electrically connected.

[0515] The atomizer module 20 includes an atomizing shell 22, a comb tooth assembly 224 and a nozzle 23. The nozzle 23 has a mist outlet 23a and is arranged on the atomizing shell 22. The atomizing shell 22 has an air channel 22b and a liquid storage chamber 22a. The air compressor 11 is connected to one end of the air channel 22b, and the nozzle 23 is connected to the other end of the air channel 22b and the liquid storage chamber 22a respectively, so that the airflow from the air compressor 11 atomizes the atomized liquid from the liquid storage chamber 22a to generate an aerosol.

[0516] The comb tooth assembly 224 is arranged at one end of the atomizing shell 22 close to the mist outlet 23a. The comb tooth assembly 224 includes a comb tooth piece 2241 located on the peripheral side of the mist outlet 23a. Along the circumference of the nozzle 23, the comb tooth piece 2241 has a first comb tooth surface 224a and a second comb tooth surface 224b on opposite sides. At the end of the comb tooth piece 2241 away from the mist outlet 23a, the first comb tooth surface 224a and the second comb tooth surface 224b are connected, and the distance between the first comb tooth surface 224a and the second comb tooth surface 224b gradually increases towards the direction close to the mist outlet 23a.

[0517] Specifically, for ease of description, the embodiments of the present application are described using the electronic atomization device as a scalp atomization drug delivery device as an example.

[0518] The comb tooth assembly 224 is arranged at the end of the atomizing shell 22 near the mist outlet 23a. Therefore, during use, the user can use the comb tooth assembly 224 located at the end to separate the hair so that the atomized liquid flowing out of the mist outlet 23a can reach the scalp and get as little hair as possible.

[0519] The comb teeth 2241 are located around the mist outlet 23a to avoid the mist outlet direction of the mist outlet 23a, so as to avoid affecting the mist outlet effect of the mist outlet 23a while separating the hair.

[0520] The outer surface of the comb tooth member 2241 has a first comb tooth surface 224a and a second comb tooth surface 224b. The first comb tooth surface 224a and the second comb tooth surface 224b intersect at the end of the comb tooth member 2241 away from the mist outlet 23a. The first comb tooth surface 224a and the second comb tooth surface 224b are inclined relative to each other, and from the side away from the mist outlet 23a to the side close to the mist outlet 23a, the first comb tooth surface 224a and the second comb tooth surface 224b are inclined relative to each other in a direction away from each other. In this way, the distance between the first comb tooth surface 224a and the second comb tooth surface 224b can be gradually increased to facilitate separation of hair.

[0521] It should be noted that the shapes of the first comb-tooth surface 224a and the second comb-tooth surface 224b are not limited, such as a flat surface, a curved surface, etc.

[0522] For example, the first comb tooth surface 224a and the second comb tooth surface 224b are planes inclined to each other, and the angle between the first comb tooth surface 224a and the second comb tooth surface 224b is greater than or equal to 30° and less than or equal to 120°.

[0523] Specifically, the first comb tooth surface 224a and the second comb tooth surface 224b are planar, which facilitates hair separation. Furthermore, the angle between the two surfaces is set between 30° and 120°, which can achieve a better hair separation effect. For example, the angle is greater than or equal to 45° and less than or equal to 90°. Setting the angle between 45° and 90° can also achieve a better hair separation effect.

[0524] The first comb-tooth surface 224a and the second comb-tooth surface 224b are connected to each other on the side facing away from the mist outlet 23a, and the specific connection method is not limited.

[0525] For example, see Figure 36 , the junction of the first comb tooth surface 224a and the second comb tooth surface 224b away from the mist outlet 23a has a smooth transition. Specifically, the smooth transition means that the intersection of the first comb tooth surface 224a and the second comb tooth surface 224b is smoothly transitioned, and there are no obvious protrusions, folded edges and mutations between the two. For example, the intersection of the first comb tooth surface 224a and the second comb tooth surface 224b is connected by a smooth transition of the arc surface. It should be noted that the use of a smooth transition method can avoid the existence of mutations at the intersection, so that the end of the comb tooth part 2241 away from the mist outlet 23a will not be too sharp, which can reduce the problem of the comb tooth part 2241 scratching the scalp or damaging the hair due to its sharpness.

[0526] The electronic atomization device of the embodiment of the present application includes a host module 10 and an atomizer module 20. The comb tooth assembly 224 of the atomizer module 20 is arranged at one end of the atomization housing 22 close to the mist outlet 23a, and the comb tooth assembly 224 includes a comb tooth piece 2241 located on the side of the mist outlet 23a. Thus, when applying medicine to the scalp through the electronic atomization device, the comb tooth piece 2241 located on the side of the mist outlet 23a can separate the hair, effectively separate the hair, and enable the liquid medicine to be better applied to the scalp. On the other hand, along the circumference of the nozzle 23, the opposite sides of the comb tooth piece 2241 respectively have a first comb tooth surface 224a and a second comb tooth surface 224b. At the end of the comb tooth piece 2241 facing away from the mist outlet 23a, the first comb tooth surface 224a and the second comb tooth surface 224b are connected, and the distance between the first comb tooth surface 224a and the second comb tooth surface 224b gradually increases towards the direction close to the mist outlet 23a. The design adopts a method in which the distance gradually increases towards the mist outlet 23a, so that the comb tooth part 2241 can better separate the hair through the first comb tooth surface 224a and the second comb tooth surface 224b, which can reduce the risk of hair blocking the mist outlet 23a, thereby achieving a better distribution effect and facilitating the electronic atomization device to discharge mist and apply medicine.

[0527] In one embodiment, please refer to Figure 36 and Figure 39The comb-tooth member 2241 includes a first comb-tooth portion 2242 and a second comb-tooth portion 2243. Along the circumference of the nozzle 23, the first comb-tooth portion 2242 has a first comb-tooth surface 224a on a side facing away from the second comb-tooth portion 2243, and the second comb-tooth portion 2243 has a second comb-tooth surface 224b on a side facing away from the first comb-tooth portion 2242. The first comb-tooth portion 2242 and the second comb-tooth portion 2243 are connected to each other at ends facing away from the mist outlet 23a. As they approach the mist outlet 23a, the first comb-tooth portion 2242 and the second comb-tooth portion 2243 are inclined away from each other and both extend to the end of the comb-tooth member 2241 near the mist outlet 23a. The first comb-tooth portion 2242 and the second comb-tooth portion 2243 are spaced apart from each other at least on the side near the mist outlet 23a. This improves the distribution effect and facilitates application of medication to the scalp.

[0528] Specifically, the first comb portion 2242 has a first comb surface 224a, and the second comb portion 2243 has a second comb surface 224b. The first comb portion 2242 and the second comb portion 2243 are inclined relative to each other, so that the ends facing away from the mist outlet 23a are connected together, while the ends closer to the mist outlet 23a are spaced apart. As a result, the comb member 2241 is roughly "arrow" shaped, and its cross-section is roughly "V" shaped, which can be used to separate hair to facilitate scalp medication.

[0529] It should be noted that the first comb tooth surface 224a and the second comb tooth surface 224b both extend to the end of the comb tooth part 2241 close to the mist outlet 23a. Thus, the first comb tooth surface 224a and the second comb tooth surface 224b are long enough to ensure the distribution effect of the comb tooth part 2241.

[0530] A space is formed between the first comb-tooth portion 2242 and the second comb-tooth portion 2243 at one end close to the mist outlet 23a. In fact, in other embodiments, the first comb-tooth portion 2242 and the second comb-tooth portion 2243 at one end close to the mist outlet 23a can also be connected together without being separated.

[0531] In one embodiment, please refer to Figure 41 The first comb tooth surface 224a and the second comb tooth surface 224b both extend to the end of the comb tooth member 2241 near the mist outlet 23a. The first comb tooth surface 224a and the second comb tooth surface 224b are connected by a smooth arc transition on the side facing away from the mist outlet 23a. The first comb tooth surface 224a and the second comb tooth surface 224b are connected by a smooth arc transition on the side close to the mist outlet 23a. This makes it easier to separate the hair and apply medication to the scalp.

[0532] Specifically, the first comb tooth surface 224a and the second comb tooth surface 224b both extend from the end of the comb tooth piece 2241 away from the mist outlet 23a to the end of the comb tooth piece 2241 close to the mist outlet 23a. Thus, the first comb tooth surface 224a and the second comb tooth surface 224b can be long enough to ensure the distribution effect of the comb tooth piece 2241.

[0533] The first comb tooth surface 224a and the second comb tooth surface 224b are both formed with arcuate transitions on the side facing away from the mist outlet 23a and the side facing the mist outlet 23a, respectively. This makes the transition between the first comb tooth surface 224a and the second comb tooth surface 224b smoother, thus preventing damage to the scalp and hair caused by overly sharp joints. For example, the comb tooth member 2241 is generally triangular in shape, and its cross-section is generally an arcuate triangle.

[0534] In one embodiment, please refer to Figure 40 The comb tooth member 2241 further includes a third comb tooth surface 224c and a fourth comb tooth surface 224d. Along the circumference of the nozzle 23, the third comb tooth surface 224c is located on the same side of and in contact with the first comb tooth surface 224a, and the fourth comb tooth surface 224d is located on the same side of and in contact with the second comb tooth surface 224b. At the end of the comb tooth member 2241 near the mist outlet 23a, the third comb tooth surface 224c and the fourth comb tooth surface 224d are in contact, and the distance between the third comb tooth surface 224c and the fourth comb tooth surface 224d gradually increases as they move away from the mist outlet 23a. This facilitates separation of hair for easier scalp application.

[0535] Specifically, the first comb tooth surface 224a and the second comb tooth surface 224b do not extend to the end of the comb tooth member 2241 close to the mist outlet 23a. The comb tooth member 2241 has a third comb tooth surface 224c and the first comb tooth surface 224a on one side along the circumference of the nozzle 23, and the third comb tooth surface 224c is located on the side of the first comb tooth surface 224a close to the mist outlet 23a. The comb tooth member 2241 has a fourth comb tooth surface 224d and a second comb tooth surface 224b on the other side along the circumference of the nozzle 23, and the fourth comb tooth surface 224d is located on the side of the second comb tooth surface 224b close to the mist outlet 23a.

[0536] That is, the third comb tooth surface 224c corresponds to the fourth comb tooth surface 224d, and the first comb tooth surface 224a corresponds to the second comb tooth surface 224b. From the side away from the mist outlet 23a to the side close to the mist outlet 23a, the first comb tooth surface 224a and the second comb tooth surface 224b are inclined in a direction away from each other. Meanwhile, the third comb tooth surface 224c and the fourth comb tooth surface are inclined in a direction toward each other.

[0537] For example, if the comb tooth member 2241 is a "diamond-shaped" structure, its cross-sectional shape is a diamond.

[0538] The number of comb teeth 2241 is not limited, and can be one or more.

[0539] In one embodiment, please refer to Figure 36 The comb assembly 224 includes a plurality of comb teeth 2241 spaced apart along the circumference of the nozzle 23. A comb tooth 2241 is provided on opposite sides of the nozzle 23 along the fourth direction, and a comb tooth 2241 is provided on opposite sides of the nozzle 23 along the fifth direction. The fourth and fifth directions are perpendicular. This allows the electronic atomization device to comb hair in at least four directions, making it easier to apply medication to the scalp.

[0540] Specifically, the comb tooth assembly 224 includes a plurality of comb tooth members 2241 , each comb tooth member 2241 is arranged on the peripheral side of the nozzle 23 and is spaced apart along the circumference of the nozzle.

[0541] The comb assembly 224 may include only two comb members 2241 located on opposite sides of the nozzle 23 along the fourth direction, and two comb members 2241 located on opposite sides of the nozzle 23 along the fifth direction, for a total of four comb members 2241. Because the fourth direction is perpendicular to the fifth direction, when the electronic atomization device is moved in different directions, the comb members 2241 located in different positions can comb and separate the hair accordingly.

[0542] Of course, in other embodiments, the comb tooth assembly 224 may also include comb tooth pieces 2241 disposed at other positions.

[0543] For example, see Figure 39 Comb teeth members 2241 are further provided at the intervals between the comb teeth members 2241 on one side of the nozzle 23 along the fourth direction and the fifth direction.

[0544] Specifically, in addition to the two comb-tooth members 2241 on opposite sides of the nozzle 23 along the fourth direction and the two comb-tooth members 2241 on opposite sides along the fifth direction, another comb-tooth member 2241 is provided between the comb-tooth member 2241 provided along the fourth direction and the adjacent comb-tooth member 2241 provided along the fifth direction. The number of comb-tooth members 2241 is not limited, and may be one or more.

[0545] Thus, the electronic atomization device can include at least eight comb teeth 2241 with different directions, which can ensure that the hair is effectively separated.

[0546] In one embodiment, please refer to Figure 36 and Figure 39The comb assembly 224 includes a plurality of comb members 2241 spaced apart along the circumference of the nozzle 23. The comb assembly 224 includes a plurality of comb posts 2244. Each comb post 2244 is spaced apart along the circumference of the nozzle 23 and is located on the outer circumference of each comb member 2241. In the radial direction of the nozzle 23, the comb posts 2244 are staggered with adjacent comb members 2241. Thus, the provision of the comb posts 2244 facilitates hair detangling, which in turn facilitates the comb members 2241 to comb the hair, thereby improving the drug delivery effect.

[0547] Specifically, the comb column 2244 is a columnar structure, which can be a cylinder, a prism, a truncated cone structure, etc.

[0548] The comb tooth assembly 224 includes multiple comb tooth pieces 2241 and multiple comb tooth posts 2244. Each comb tooth piece 2241 and each comb tooth post 2244 is arranged at intervals around the circumference of the nozzle 23, and each comb tooth piece 2241 is in the inner circle close to the nozzle 23, while each comb tooth post 2244 is in the outer circle away from the nozzle 23.

[0549] It should be noted that the staggered arrangement between the comb column 2244 and the adjacent comb piece 2241 can avoid the comb column 2244 and the comb piece 2241 being in the same radial direction, thereby avoiding the comb column 2244 from blocking the comb piece 2241 and preventing the distribution effect of the comb piece 2241 from being reduced.

[0550] In one embodiment, please refer to Figure 35 The atomizing housing 22 includes an atomizing bomb 221 and a comb-tooth mounting base 226. The atomizing bomb 221 has a liquid storage chamber 22a. The nozzle 23 is located in the comb-tooth mounting base 226, and one end of the nozzle 23 having a mist outlet 23a extends out of the comb-tooth mounting base 226. The opposite ends of the comb-tooth mounting base 226 are detachably connected to the atomizing bomb 221 and the comb-tooth assembly 224, respectively. This facilitates the installation of the comb-tooth assembly 224 on the atomizing bomb 221 and the disassembly of the atomizing bomb 221.

[0551] Specifically, the comb tooth mounting base 226 is used to connect the atomizing bomb 221 and the comb tooth assembly 224. In fact, a cavity for accommodating the nozzle 23 is formed in the comb tooth mounting base 226. One end of the nozzle 23 having a mist outlet 23a extends out of the cavity to facilitate mist discharge to the outside.

[0552] The atomizing bomb 221 is detachably connected to the comb tooth mounting seat 226 , thereby making it easy to remove the atomizing bomb 221 to achieve replacement of the atomizing bomb 221 .

[0553] In one embodiment, please refer to Figure 35 and Figure 36The comb assembly 224 includes a mounting plate 2245 having a mounting hole 224e. The mounting plate 2245 is detachably connected to the comb mounting base 226. The end of the nozzle 23 having the mist outlet 23a is inserted into the mounting hole 224e. The comb member 2241 is disposed on the end surface of the mounting plate 2245 near the mist outlet 23a. Thus, by providing the mounting plate 2245, the comb member 2241 can be easily installed around the mist outlet 23a. At the same time, the comb member 2241 can be securely mounted on the comb mounting base 226, thereby improving structural stability.

[0554] Specifically, the mounting hole 224e is used for one end of the nozzle 23 having the mist outlet 23a to pass through, and the comb tooth piece 2241 is arranged on the side of the mounting plate 2245 away from the comb tooth mounting seat 226, so that the comb tooth piece 2241 can separate the hair to allow the atomized liquid flowing out of the mist outlet 23a to reach the scalp.

[0555] It should be noted that the mounting plate 2245 and the comb teeth 2241 can be an integrally formed structure or a separately formed structure.

[0556] In one embodiment, please refer to Figures 36 to 38 A portion of the outer edge of the mounting plate 2245 protrudes toward the side near the comb-tooth mounting seat 226 to form a plurality of first positioning members 2246 spaced apart along the circumference of the nozzle 23. A first snap-in notch 224f is formed between two adjacent first positioning members 2246. A portion of the end surface of the comb-tooth mounting seat 226 on the side near the mounting plate 2245 protrudes to form a plurality of engaging members 2261 spaced apart along the circumference of the nozzle 23. The engaging members 2261 are respectively engaged in the first snap-in notch 224f to engage the mounting plate 2245 with the comb-tooth mounting seat 226. This improves the connection stability between the mounting plate 2245 and the comb-tooth mounting seat 226.

[0557] Specifically, the first positioning member 2246 is a protruding structure protruding from the end face of the mounting plate 2245 close to the comb tooth mounting seat 226. The first positioning member 2246 is located at the outer edge of the mounting plate 2245, and each first positioning member 2246 is arranged at intervals along the circumference of the mounting plate 2245 (which is also the circumference of the nozzle 23).

[0558] Since adjacent first positioning members 2246 are spaced apart, first bayonet holes 224f are formed at the spaced apart locations. The clamping members 2261 are protruding structures protruding toward the side close to the mounting plate 2245, and their positions, numbers, and shapes all correspond to the first bayonet holes 224f.

[0559] When the mounting plate 2245 is detachably mounted on the comb tooth mounting seat 226 , the clamping member 2261 is correspondingly clamped into the first clamping port 224 f , thereby enabling a stable connection between the mounting plate 2245 and the comb tooth mounting seat 226 .

[0560] In one embodiment, please refer to Figures 36 to 38 , a partial area of ​​the end surface of the mounting plate 2245 close to the comb tooth mounting seat 226 is protruded to form a plurality of second positioning members 2247 arranged at intervals along the circumference of the nozzle 23, and each second positioning member 2247 is located on the inner circumference of each first positioning member 2246, and a second bayonet 224g is formed at the interval between two adjacent second positioning members 2247. Along the radial direction of the nozzle 23, the second positioning members 2247 and the first positioning members 2246 are arranged at intervals corresponding to each other, so that an annular groove 224h is formed at the interval.

[0561] A partial area of ​​the end surface of the comb tooth mounting seat 226 on one side close to the mounting plate 2245 protrudes to form a retaining ring 2262 extending circumferentially around the nozzle 23. When the mounting plate 2245 is engaged with the comb tooth mounting seat 226, the retaining ring 2262 is engaged in the annular groove 224h, and the retaining member 2261 is correspondingly engaged in the second retaining port 224g.

[0562] Specifically, the second positioning member 2247 is a protruding structure protruding from the end face of the mounting plate 2245 close to the comb tooth mounting seat 226. Each second positioning member 2247 is arranged at circumferential intervals along the nozzle 23, and the second positioning member 2247 is located on the side of each first positioning member 2246 close to the nozzle 23.

[0563] The number of second positioning members 2247 is the same as that of first positioning members 2246, and they are spaced apart in a one-to-one correspondence with the first positioning members 2246. On the one hand, each second positioning member 2247 is able to penetrate the first positioning member 2246 in the radial direction at the interval, thereby forming an annular groove 224h. On the other hand, because adjacent second positioning members 2247 are spaced apart, a second bayonet 224g is formed at the interval.

[0564] The snap ring 2262 is a protruding structure on the comb tooth mounting seat 226 that protrudes toward the side close to the mounting plate 2245. Its setting position corresponds to the annular snap groove 224h.

[0565] When the mounting plate 2245 is detachably mounted on the comb tooth mounting seat 226, the clamping piece 2261 clamped in the first clamping port 224f extends to the second clamping port 224g, and the clamping ring 2262 is clamped in the annular clamping groove 224h, thereby enabling a stable connection between the mounting plate 2245 and the comb tooth mounting seat 226.

[0566] In one embodiment, please refer to Figures 36 to 38The mounting plate 2245 has a partially protruding end surface on the side near the comb tooth mounting seat 226 to form a plurality of engaging posts 2248 spaced apart along the circumference of the nozzle 23. The comb tooth mounting seat 226 has a partially recessed end surface on the side near the mounting plate 2245 to form a plurality of engaging holes 226a spaced apart along the circumference of the nozzle 23. The engaging posts 2248 are correspondingly mounted in the engaging holes 226a, thereby engaging the mounting plate 2245 with the comb tooth mounting seat 226. This ensures a stable connection between the mounting plate 2245 and the comb tooth mounting seat 226.

[0567] Specifically, the comb tooth mounting base 226 has a plurality of engaging holes 226a on its end surface near the mounting plate 2245. The engaging holes 226a can be through-holes that penetrate the end surface of the comb tooth mounting base 226, or recessed holes that do not penetrate the end surface. The engaging engagement of the engaging posts 2248 with the engaging holes 226a provides a more stable connection between the mounting plate 2245 and the comb tooth mounting base 226.
