Furthermore, the air compressor's snap-fit ​​connection to the main unit bracket enhances the stability of the air compressor installation. The atomizing housing incorporates at least a portion of the air passage and a liquid reservoir through injection molding.

[0064] In this application, the orientations or positional relationships of "first direction" and "second direction" are based on the orientations or positional relationships shown in Figure 3, the orientations or positional relationships of "third direction" are based on the orientations or positional relationships shown in Figure 9, and the orientations or positional relationships of "fourth direction" and "fifth direction" are based on the orientations or positional relationships shown in Figure 36. It should be understood that these orientational terms are for the convenience of describing this application and for simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application.

[0065] One embodiment of this application provides an electronic atomizing device. Please refer to Figures 1 and 2. The electronic atomizing device includes a main unit module 10 and an atomizer module 20.

[0066] The main unit module 10 includes a power supply component 13, a main unit bracket 12, an air compressor 11, and a main unit housing 16. The power supply component 13, the air compressor 11, and the main unit bracket 12 are all detachably installed inside the main unit housing 16. The power supply component 13 and the air compressor 11 are electrically connected. The power supply component 13 and the air compressor 11 are both installed on the main unit bracket 12, and the air compressor 11 is snapped into the main unit bracket 12.

[0067] The atomizer module 20 includes an atomizing housing 22 and a nozzle 23 disposed on the atomizing housing 22. The atomizing housing 22 has an air passage 22b and a liquid storage chamber 22a. At least a portion of the air passage 22b is injection molded. The liquid storage chamber 22a is used to store the atomizing medium to be atomized. The atomizing housing 22 is detachably connected to the main unit housing 16.

[0068] The air compressor 11 is connected to one end of the air passage 22b, and the nozzle 23 is connected to the other end of the air passage 22b and the liquid storage chamber 22a respectively, so that the airflow from the air compressor 11 atomizes the atomizing liquid in the liquid storage chamber 22a to generate aerosol.

[0069] Specifically, the electronic atomizing device in this application embodiment can be any type of atomizing device, such as a scalp atomization drug delivery device, where the atomizing liquid stored in the atomizer module 20 is a drug solution, such as minoxidil. Alternatively, the electronic atomizing device can be an electronic cigarette, where the atomizing liquid stored in the atomizer module 20 is e-liquid.

[0070] The air compressor 11 in this embodiment refers to a device capable of compressing gas, such as an air pump.

[0071] The air compressor 11 is electrically connected to the power supply unit 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 an electronic atomization device that atomizes the atomizing liquid to generate an aerosol.

[0072] The atomizing housing 22 can store atomizing liquid. The atomizing liquid in the 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 atomizing liquid is atomized to generate an aerosol.

[0073] In fact, the nozzle 23 also has a mist outlet 23a, through which the aerosol generated by the atomization of the atomizing liquid can reach the outside of the atomizer module 20.

[0074] The power supply assembly 13, the air compressor 11, and the main unit bracket 12 are all detachably installed inside the main unit housing 16. The air compressor 11 is snapped into the main unit bracket 12. This facilitates the disassembly and assembly of the power supply assembly 13, the air compressor 11, and the main unit bracket 12, and also improves the installation stability of the air compressor 11 through the snap-fit ​​connection.

[0075] It should be noted that the power supply assembly 13 is also mounted on the host bracket 12, but the specific installation method of the power supply assembly 13 can be set according to the actual situation. For example, the power supply assembly 13 can be snapped into the host bracket 12.

[0076] Of course, the power supply assembly 13 can also be installed in other ways, such as plugging, bonding, or fastening.

[0077] The atomizing housing 22 is detachably connected to the main unit housing 16, meaning that the main unit module 10 and the atomizer module 20 are detachable from each other. Therefore, on the one hand, by detaching the atomizer module 20 from the main unit module 10, it is easy to 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 single unit first, then the atomizer module 20 can be assembled into a single unit, and finally the atomizer module 20 and the main unit module 10 can be assembled together, greatly improving the ease of installation of the electronic atomizing device.

[0078] The air passage 22b within the atomizer module 20 can be partially injection molded from the atomizing housing 22, or the entire air passage 22b can be injection molded from the atomizing housing 22. This reduces the use of tubing, improving installation convenience and reducing the risk of poor sealing when tubing is used as the air passage 22b structure.

[0079] The electronic atomizing device provided in this application embodiment includes a main unit module 10 and an atomizer module 20. The power supply component 13, air compressor 11, and main unit bracket 12 are all detachably mounted within the main unit housing 16. The power supply component 13 and air compressor 11 are electrically connected, and both are mounted on the main unit bracket 12. This detachable installation method facilitates the disassembly and assembly of the power supply component 13, air compressor 11, and main unit bracket 12. Simultaneously, the air compressor 11 is snapped onto the main unit bracket 12, improving the stability of the air compressor 11 installation. The atomizing housing 22 is injection-molded with at least a portion of the air passage 22b and the liquid storage chamber 22a. This allows at least a portion of the air passage 22b to be directly formed within the atomizing housing 22, minimizing the need for flexible tubing as the air passage 22b structure, thus reducing assembly difficulty and making the atomizer module 20 assembly more convenient. Meanwhile, the atomizing housing 22 is detachably connected to the main unit housing 16, facilitating the assembly and disassembly of the atomizer module 20 and the main unit module 10, thereby facilitating the maintenance and replacement of either the atomizer module 20 or the main unit module 10. Therefore, the electronic atomizing device of this embodiment is easy to assemble, greatly improving the convenience of using the electronic atomizing device.

[0080] In one embodiment, referring to Figures 2 to 4, the main unit 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 and spaced apart. One end of the air compressor 11 along a first direction has an air outlet 11a, 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 main unit bracket 12 along a second direction is open to form an installation inlet 12b communicating with the mounting cavity 12a; wherein the second direction is perpendicular to the first direction. Therefore, the air compressor 11 and the power supply assembly 13 can be installed into the mounting cavity 12a through the installation inlet 12b, facilitating the assembly and disassembly of the air compressor 11 and the power supply assembly 13.

[0081] Specifically, both the power supply assembly 13 and the air compressor 11 are housed within the mounting cavity 12a, and the main support bracket 12 secures both the power supply assembly 13 and the air compressor 11. Furthermore, the power supply assembly 13 and the air compressor 11 are spaced apart to prevent them from colliding due to loosening and causing structural damage. Thus, on the one hand, by setting up the main support bracket 12, the air compressor 11 is secured within the mounting cavity 12a, improving the stability of the air compressor 11 installation. Therefore, during the use of the electronic atomizing device, the air compressor 11 is less likely to loosen, ensuring a secure installation and achieving a stable air supply to the nozzle 23. On the other hand, the spaced-apart installation method between the power supply assembly 13 and the air compressor 11 prevents them from colliding with each other, thereby avoiding damage to both.

[0082] Specifically, the power supply assembly 13 is located at the end of the air compressor 11 away from the air outlet 11a, and is spaced apart from the air compressor 11 along the first direction.

[0083] The installation inlet 12b is located on one side of the installation cavity 12a along the second direction, and the installation inlet 12b communicates with the installation cavity 12a.

[0084] It should be noted that a portion of the main unit bracket 12 along one side of the second direction may be open to form the installation entrance 12b. Depending on the actual situation, the entire area of ​​the main unit bracket 12 along one side of the second direction may also be open to form the installation entrance 12b.

[0085] In one embodiment, referring to Figures 2 to 4, on opposite sides of the installation inlet 12b, a portion of the wall of the main unit bracket 12 protrudes to form spaced 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 peripheral 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, and the use of bracket clips 121 also facilitates the assembly and disassembly of the air compressor 11.

[0086] Specifically, a bracket buckle 121 is formed on the walls on both sides of the installation inlet 12b, and the two bracket buckles 121 are spaced apart from each other so that the air compressor 11 can pass through the installation inlet 12b through the gap and then be installed into the installation cavity 12a.

[0087] After the air compressor 11 is installed in the mounting cavity 12a, the bracket buckle 121 fits against the outer surface of the air compressor 11, so as to restrict the air compressor 11 from leaving the mounting cavity 12a from the mounting inlet 12b by abutting against the air compressor 11, thereby achieving the purpose of locking the air compressor 11 in the mounting cavity 12a.

[0088] It should be noted that the specific shape of the bracket buckle 121 is not limited.

[0089] For example, referring to Figure 5, along the protruding direction of the bracket latches 121, the two bracket latches 121 bend towards each other, and the bracket latches 121 elastically deform towards each other to allow the air compressor 11 to engage in the mounting cavity 12a. This improves the abutment effect of the bracket latches 121 on the air compressor 11, thereby enhancing the installation stability of the air compressor 11 within the mounting cavity 12a.

[0090] Specifically, the protruding direction of the bracket clip 121 refers to the direction in which the bracket clip 121 protrudes through other areas of the wall of the main unit bracket 12 and extends away from the mounting cavity 12a.

[0091] In fact, from the side closer to the mounting cavity 12a to the side farther away from the mounting cavity 12a, the two bracket clips 121 are bent in a direction that brings them closer to each other. As a result, after the air compressor 11 is inserted into the mounting cavity 12a, the bracket clips 121 can fit and abut against the outer surface of the air compressor 11 well, so as to limit the air compressor 11 within the mounting cavity 12a.

[0092] It should be noted that the bracket buckle 121 is a buckle structure with a certain elastic deformation capability.

[0093] Therefore, during the process of installing the air compressor 11 from the outside into the installation cavity 12a through the installation inlet 12b, the air compressor 11 pushes the two bracket buckles 121 from the outside, causing the two bracket buckles 121 to undergo elastic deformation and shift in a direction away from each other, thereby increasing the distance between the two bracket buckles 121, which makes it easier for the air compressor 11 to be inserted into the installation cavity 12a.

[0094] Similarly, during the process of removing the air compressor 11 from the mounting cavity 12a through the mounting inlet 12b, the air compressor 11 pushes the two bracket latches 121 from the inside, causing the two bracket latches 121 to undergo elastic deformation and shift in a direction away from each other, thereby increasing the distance between the two bracket latches 121, which makes it easier for the air compressor 11 to be inserted into the mounting cavity 12a.

[0095] It should be noted that the specific shape of the bracket buckle 121 can be set according to the actual situation.

[0096] For example, bracket buckle 121 is a curved plate.

[0097] For example, as shown in Figures 5 and 6, the sides of the two bracket clips 121 that are close to each other each have abutment surfaces 121a, which are curved surfaces 271a that correspond to and fit against the outer periphery of the air compressor 11. This improves the effectiveness of the bracket clips 121 in preventing the air compressor 11 from coming out of the mounting cavity 12a, and further enhances the installation stability of the air compressor 11.

[0098] Specifically, after the air compressor 11 is inserted into the mounting 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, it is easy for the abutting surface 121a to fit against the outer surface of the air compressor 11.

[0099] It should be noted that the outer surface of the air compressor 11 can also be a curved surface 271a, and the curvature of the outer surface of the air compressor 11 and the abutment surface 121a can be the same. This allows the abutment surface 121a to fit more tightly with the air compressor 11, resulting in higher installation stability of the air compressor 11.

[0100] For example, referring to Figure 6, each of the two bracket clips 121 has an abutment surface 121a and a guide surface 121b on the side where they are close to each other. The guide surface 121b is located on the side of the abutment surface 121a away from the mounting cavity 12a. The abutment surface 121a is a curved surface 271a that corresponds to and fits against the outer peripheral surface of the air compressor 11. Along the protruding direction of the bracket clips 121, the guide surface 121b is an inclined surface that is inclined in a direction away from each other. This facilitates the installation of the air compressor 11 into the mounting cavity 12a.

[0101] Specifically, the guide surface 121b is an inclined surface, and along the protruding direction of the bracket latch 121, that is, from the side closer to the mounting cavity 12a to the side farther away from the mounting cavity 12a, the guide surface 121b is inclined in a direction away from each other. In other words, the distance between the two guide surfaces 121b gradually decreases from the side farther away from the mounting cavity 12a to the side closer to the mounting cavity 12a. Therefore, during the process of the air compressor 11 being inserted into the mounting cavity 12a through the installation inlet 12b, when the air compressor 11 first contacts the two guide surfaces 121b, the distance between the two guide surfaces 121b is relatively large, allowing the air compressor 11 to easily engage with them. As the air compressor 11 gradually moves towards 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 latches 121 to elastically deform in a direction away from each other, thereby guiding the air compressor 11 into the mounting cavity 12a.

[0102] In one embodiment, referring to Figures 4 and 5, a portion of the cavity wall of the mounting cavity 12a protrudes into the cavity 12a to form a limiting portion 122. The limiting portion 122 abuts against the power supply assembly 13 and the air compressor 11 respectively, thereby separating the power supply assembly 13 and the air compressor 11. This further reduces the risk of collision between the power supply assembly 13 and the air compressor 11, improving structural safety.

[0103] Specifically, the limiting part 122 is a protruding structure formed by the protrusion of the cavity wall of the mounting cavity 12a. By abutting against the air compressor 11, it can limit the air compressor 11 from shaking towards the side closer to the power supply assembly 13. At the same time, by abutting against the power supply assembly 13, the limiting part 122 can also limit the power supply assembly 13 from shaking towards 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 them colliding with each other due to shaking.

[0104] It should be noted that the specific shape of the limiting part 122 is not limited.

[0105] For example, the limiting part 122 is a protruding plate, one side of which abuts against the end face of the air compressor 11 near the power supply assembly 13, and the other side of which abuts against the end face of the power supply assembly 13 near the air compressor 11.

[0106] For example, the limiting part 122 includes a first protrusion, a second protrusion, and a third protrusion spaced apart along a first direction. One end of the air compressor 11 abuts against the end of the main support 12, and the other end of the air compressor 11 abuts against the first protrusion. The power supply assembly 13 is disposed at the gap between the second and third protrusions, with its opposite ends abutting against the second and third protrusions respectively. This greatly improves the installation stability of the power supply assembly 13 and the air compressor 11.

[0107] In one embodiment, referring to Figures 5 and 7, the main unit module 10 includes a circuit board 14, and the main unit 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 face 123a facing away from the mounting cavity 12a. A portion of the mounting end face 123a protrudes to form a third snap-fit ​​member 1231. The circuit board 14 is disposed on the mounting end face 123a and snaps into the third snap-fit ​​member 1231. This greatly improves the installation stability of the circuit board 14.

[0108] Specifically, the circuit board 14 is also mounted on the main unit bracket 12. By engaging with the third connector 1231, the installation stability of the circuit board 14 can be greatly improved.

[0109] Furthermore, the circuit board 14 is not installed inside the mounting cavity 12a of the main unit bracket 12, but rather on the outer end face of the end of the main unit bracket 12; that is, the circuit board 14 is installed outside the mounting cavity 12a. Therefore, the power supply assembly 13 and the circuit board 14 can be separated by the mounting end wall 123 at the end of the main unit bracket 12, preventing damage to the 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, fires, or other malfunctions of the main unit.

[0110] Meanwhile, mounting the circuit board 14 on the mounting end face 123a facilitates the disassembly and assembly of the circuit board 14, thereby facilitating subsequent maintenance and replacement.

[0111] The third connector 1231 is a protruding structure formed by the mounting end face 123a, and its specific shape is not limited.

[0112] As exemplarily, referring to Figures 7 and 8, the third snap-fit ​​component 1231 includes a fixing post 1232 disposed on the mounting end face 123a. The circuit board 14 has a fixing hole, and the fixing post 1232 passes through the fixing hole to snap the circuit board 14 onto the mounting end face 123a. This improves the mounting stability of the circuit board 14.

[0113] Specifically, when the circuit board 14 is mounted on the mounting end face 123a, the fixing post 1232 is inserted into the fixing hole to restrict the movement of the circuit board 14, which can improve the stability of the circuit board 14.

[0114] The fixing posts 1232 and the fixing holes can be in one-to-one correspondence. Depending on the actual situation, the number of fixing holes can be greater than the number of fixing posts 1232, or the number of fixing posts 1232 can be greater than the number of fixing holes.

[0115] The number of fixing posts 1232 and fixing holes is unlimited. For example, the third snap-fit ​​component 1231 includes multiple fixing posts 1232, and the circuit board 14 has multiple fixing holes, with the fixing posts 1232 correspondingly inserted into the fixing holes.

[0116] For example, referring to Figures 7 and 8, the third snap-fit ​​component 1231 also includes a snap-fit ​​plate 1233 disposed on the mounting end face 123a. A portion of the snap-fit ​​plate 1233 protrudes to form a first abutment portion 1234 on the side of the circuit board 14. When the circuit board 14 is mounted on the fixing post 1232 through the fixing hole, the first abutment portion 1234 abuts against the side of the circuit board 14 away from the mounting end face 123a. This further improves the mounting stability of the circuit board 14.

[0117] Specifically, when the circuit board 14 is mounted on the mounting end face 123a, the fixing post 1232 passes through the fixing hole, and the first abutting part 1234 of the snap-fit ​​plate 1233 abuts against the side of the circuit board 14 away from the mounting end face 123a, thereby further restricting the movement of the circuit board 14 away from the mounting end face 123a and restricting the circuit board 14 from falling off the fixing post 1232, thus further improving the installation stability of the circuit board 14.

[0118] In one embodiment, referring to Figures 2 and 4, the main unit module 10 further includes foam 15, at least a portion of which is located between the power supply assembly 13 and the air compressor 11, and the foam 15 is bonded to the end of the power supply assembly 13 near the air compressor 11. This buffers the relative movement between the power supply assembly 13 and the air compressor 11, reducing the risk of collision between them.

[0119] Specifically, the foam 15 may be located in only a portion of the area between the power supply assembly 13 and the air compressor 11, or it may be located entirely between the power supply assembly 13 and the air compressor 11. By placing the foam 15 between the power supply assembly 13 and the air compressor 11, the foam 15 can buffer the relative movement between the power supply assembly 13 and the air compressor 11, and can separate the power supply assembly 13 and the air compressor 11 to prevent them from colliding with each other.

[0120] At the same time, attaching the foam 15 to the power assembly 13 can prevent the foam 15 from becoming loose and shifting.

[0121] The specific type of foam 15 can be set according to the actual situation. For example, foam 15 is single-sided adhesive cotton (ethylene-vinyl acetate copolymer). It is only adhesive on the side that is attached to the power supply component 13, while the side near the air compressor 11 is not adhesive. This can prevent foam 15 from sticking to the air compressor 11 at the same time, so as to prevent the power supply component 13 from causing the air compressor 11 to shake.

[0122] In one embodiment, referring to Figure 9, the air passage 22b includes a first air passage 22ba, a second air passage 22bb, and a third air passage 22bc. One end of the first air passage 22ba has a first mold exit hole, and the other end of the first air passage 22ba is connected to the second air passage 22bb. The first mold exit hole is connected to the air compressor 11. One end of the third air passage 22bc has a second mold exit hole, and the other end of the third air passage 22bc is connected to the second air passage 22bb. The second mold exit hole is connected to the nozzle 23. The first air passage 22ba and the third air passage 22bc are respectively arranged perpendicularly to the second air passage 22bb.

[0123] Therefore, on the one hand, by connecting the first air passage 22ba to the air compressor 11 and the third air passage 22bc to the nozzle 23, with the first air passage 22ba and the third air passage 22bc respectively perpendicularly connected to the second air passage 22bb, the direction of the air passage 22b can be changed without the need for a flexible hose. This allows the air passage 22b to easily avoid other structures within the atomizing housing 22, such as the liquid storage chamber 22a. Consequently, the space within the atomizing housing 22 can be utilized more efficiently, improving the space utilization rate of the electronic atomizing device and making its structure more compact. On the other hand, by connecting the first air passage 22ba and the third air passage 22bc perpendicularly to the second air passage 22bb, the mold forming the air passage 22b can be easily demolded, and the generation of burrs when the air passage 22b collides with the mold during demolding can be reduced, thus making the airflow smoother.

[0124] Specifically, air passage 22b is a channel for high-speed airflow. The high-speed airflow from the air compressor 11 passes through the first air passage 22ba, the second air passage 22bb, and the third air passage 22bc before entering the nozzle 23.

[0125] The formation of the first airway 22ba, the second airway 22bb, and the third airway 22bc is not limited.

[0126] For example, the first air passage 22ba and the second air passage 22bb are formed by a punch-through method. This reduces the risk of burrs and allows for smoother airflow.

[0127] Specifically, during the molding process of the atomizing shell 22, after the mold used to mold the atomizing shell 22 is closed, the mold for molding the first air passage 22ba and the mold for molding the second air passage 22bb are joined by a punch-through method, so that the first air passage 22ba and the second air passage 22bb are formed after the mold is opened. It should be noted that the punch-through mold opening method can make the mold production more stable, and the burrs at the punch-through position are not easy to form. Therefore, the air passage 22b will not be blocked due to the formation of burrs, and thus the gas flow will not be affected.

[0128] For example, the second air passage 22bb and the third air passage 22bc are formed by a punch-through method. This reduces the risk of burrs and allows for smoother airflow.

[0129] Specifically, during the molding process of the atomizing shell 22, after the mold used to mold the atomizing shell 22 is closed, the mold for molding the second air passage 22bb and the mold for molding the third air passage 22bc are connected by a punch-through method so that the second air passage 22bb and the third air passage 22bc are formed after the mold is opened. This also prevents the air passage 22b from being blocked due to the formation of burrs, making the airflow smoother.

[0130] The first air passage 22ba has a first mold exit hole, which is the outlet for the mold forming the first air passage 22ba to exit after the air passage 22b is formed. In addition, after the atomizer module 20 and the main unit module 10 are installed, the first mold exit hole is used to communicate with the air compressor 11. Thus, the first mold exit hole is also the inlet for airflow to enter the air passage 22b.

[0131] The second air passage 22bb is a connecting channel between the first air passage 22ba and the third air passage 22bc, so that airflow from the first mold outlet can flow to the third air passage 22bc.

[0132] It should be noted that one end of the second air passage 22bb has a third mold exit hole, which is the outlet for the mold that forms the second air passage 22bb to exit after the air passage 22b is formed.

[0133] The third air passage 22bc has a second mold exit hole, which is an outlet for the mold forming the third air passage 22bc to exit after the air passage 22b is formed. In addition, after the atomizer module 20 and the main unit module 10 are installed, the second mold exit hole is used to communicate with the nozzle 23, so that the airflow can enter the nozzle 23 to atomize the atomized liquid flowing into the nozzle 23.

[0134] The shape and size of the first air passage 22ba, the second air passage 22bb, and the third air passage 22bc 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.

[0135] For example, the cross-sectional shape of the first airway 22ba can be circular or square, which facilitates the processing and shaping of the first airway 22ba.

[0136] For example, as shown in Figure 11, the cross-sectional shape of the second air passage 22bb is square. This facilitates the molds of the first air passage 22ba and the third air passage 22bc to make contact with the mold of the second air passage 22bb, resulting in better mold production stability. Scaling is less likely to form at the contact point, thus preventing scaling from clogging the air passage 22b and thus not affecting the flow of gas.

[0137] For example, at least one of the first air passage 22ba and the second air passage 22bb has a cross-sectional area greater than or equal to 3 mm². That is, it can be that only the cross-sectional area of ​​the first air passage 22ba is greater than or equal to 3 mm², or only the cross-sectional area of ​​the second air passage 22bb is greater than or equal to 3 mm², or both the cross-sectional areas of the first air passage 22ba and the second air passage 22bb are greater than or equal to 3 mm². This reduces airflow resistance and ensures sufficient airflow into the nozzle 23.

[0138] The first air passage 22ba and the second air passage 22bb are perpendicularly connected, and the second air passage 22bb and the third air passage 22bc are perpendicularly connected. That is, the extending direction of the first air passage 22ba is perpendicular to the extending direction of the second air passage 22bb, and the extending direction of the second air passage 22bb is also perpendicular to the extending direction of the third air passage 22bc. This allows the extending direction of the air passage 22b to bend and change direction within the atomizing housing 22, facilitating the structural layout within the atomizing housing 22.

[0139] In one embodiment, referring to the figure, the atomizing housing 22 includes an airway wall forming the second airway 22bb. The airway wall includes a first airway wall surface with a first through hole. The first airway 22ba communicates with the second airway 22bb through the first through hole. The first airway wall surface is planar. Therefore, by setting the contact surfaces between the mold of the second airway 22bb and the mold of the first airway 22ba to be planar, it is convenient for the molds forming the first airway 22ba and the second airway 22bb to be opened by a contact-through process. This improves mold production stability, reduces the likelihood of burrs forming at the contact point, and allows for smoother airflow.

[0140] Specifically, the first airway 22ba and the second airway 22bb are connected through the first through hole.

[0141] Understandably, in the second airway 22bb, the shapes of the two walls adjacent to the wall of the first airway are not limited. For example, they can be planar or curved.

[0142] The cross-sectional shape of the second airway 22bb is not limited. For example, the cross-sectional shape of the second airway 22bb can be square or trapezoidal.

[0143] In other embodiments, only the area where the first through hole is located may be planar.

[0144] In one embodiment, the atomizing housing 22 includes an airway wall forming a second airway 22bb. The airway wall includes a second airway wall surface with a second through hole. A third airway 22bc communicates with the second airway 22bb through the second through hole. The second airway wall surface is planar. Therefore, by setting the surface connecting the mold of the second airway 22bb and the mold of the third airway 22bc to a planar surface, it is convenient for the molds forming the second airway 22bb and the third airway 22bc to be opened by a contact-through process. This improves mold production stability, reduces the likelihood of burrs forming at the contact point, and allows for smoother airflow.

[0145] Specifically, the second airway 22bb and the third airway 22bc are connected through the second through hole.

[0146] Understandably, in the second airway 22bb, the shapes of the two walls adjacent to the second airway wall are not limited. For example, they can be planar or curved.

[0147] In one embodiment, referring to Figure 9, one end of the second air passage 22bb has a third mold outlet. The atomizer module 20 also includes a second sealing element 24, which is disposed at the third mold outlet to block it. Thus, after the mold of the second air passage 22bb is removed through the third mold outlet, the second sealing element 24 seals the third mold outlet, ensuring the overall airtightness of the air passage 22b and thereby ensuring the stability of the air pressure in the electronic atomizing device.

[0148] Specifically, the third ejection hole is the outlet for the mold that forms the second air passage 22bb to exit after the air passage 22b is formed. The third ejection hole is located at the end of the second air passage 22bb, which facilitates the removal of the mold.

[0149] The method by which the second seal 24 blocks the third mold outlet is not limited, as long as it prevents gas leakage from the third mold outlet. For example, the second seal 24 can be a threaded plug to mechanically block the third mold outlet. Alternatively, the second seal 24 can be silicone sealing material for the air passage 22b to seal the third mold outlet with sealant.

[0150] In one embodiment, referring to FIG9, the nozzle 23 and the second air passage 22bb are located on opposite sides of the liquid storage chamber 22a along the first direction.

[0151] Along the first direction, the first airway 22ba is located on the side of the second airway 22bb away from the liquid storage chamber 22a, and the third airway 22bc is located on the side of the second airway 22bb closer to the liquid storage chamber 22a.

[0152] The second air passage 22bb extends along a third direction so that the third air passage 22bc avoids the connection between the liquid storage chamber 22a and the nozzle 23, and is connected to the nozzle 23; wherein, the first direction is perpendicular to the third direction. Thus, by extending the second air passage 22bb along a third direction, and with the first air passage 22ba and the third air passage 22bc respectively perpendicularly connected to the second air passage 22bb, the air passage 22b in the electronic atomizing device can avoid the liquid storage chamber 22a, thereby making full use of the internal space of the atomizing shell 22, so that the structure of the electronic atomizing device is more compact.

[0153] Specifically, the first air passage 22ba is located on the side of the second air passage 22bb closer to the air compressor 11, and the first air passage 22ba is connected to the end of the second air passage 22bb. The third air passage 22bc is located on the side of the second air passage 22bb away from the air compressor 11, and the third air passage 22bc is connected to the other end of the second air passage 22bb.

[0154] The second air passage 22bb extends in a third direction. After the air passage 22b is formed, it facilitates the smooth demolding of the mold that forms the second air passage 22bb.

[0155] The first direction and the third direction are perpendicular to each other. For example, the first direction is the vertical direction of the electronic atomizing device, and the third direction is the horizontal direction of the electronic atomizing device.

[0156] In one embodiment, referring to Figure 9, the air passage 22b further has a fourth air passage 22bd. One end of the fourth air passage 22bd is connected to the second mold outlet, and the other end of the fourth air passage 22bd is connected to the nozzle 23. From the end near the second mold outlet to the end near the nozzle 23, the fourth air passage 22bd is bent to connect with the nozzle 23. By designing the fourth air passage 22bd to be bent, it can adapt to a compact spatial layout, making the electronic atomizing device more compact. On the other hand, the bending facilitates the full interaction between the high-speed airflow flowing from the air passage 22b into the nozzle 23 and the atomizing liquid, thereby improving the atomization effect of the nozzle 23.

[0157] Specifically, the formation method of the fourth air passage 22bd is not limited. For example, the second mold outlet and the nozzle 23 are connected by a connecting pipe, and the channel of the connecting pipe is the fourth channel.

[0158] Understandably, the material of the connecting tube is not limited, as long as it can be bent to connect the second mold opening and nozzle 23. For example, the connecting tube can be made of plastic or silicone.

[0159] It is understandable that the connecting pipe is connected to the second mold outlet and the nozzle 23 respectively to achieve the connection of the air passage 22b of the electronic atomizing device. The connection method between the connecting pipe and the second mold outlet and the nozzle 23 is not limited. For example, the connecting pipe is connected to the second mold outlet and the nozzle 23 respectively through a connecting joint. Or, the connecting pipe is connected to the second mold outlet and the nozzle 23 respectively by interference fit.

[0160] In one embodiment, referring to Figures 9 and 10, the atomizing housing 22 includes an adapter 222 and an atomizing bullet 221. The adapter 222 has a first air passage 22ba, a second air passage 22bb, and a third air passage 22bc. The atomizing bullet 221 has a fifth air passage 22be. The second ejector hole is connected to the nozzle 23 through the fifth air passage 22be. The adapter 222 and the atomizing bullet 221 enclose a liquid storage chamber 22a. Thus, by connecting the fifth air passage 22be of the atomizing bullet 221 to the second ejector hole and the nozzle 23 respectively, the air passage 22b of the electronic atomizing device can be kept stable, thereby ensuring the consistency of gas flow within the air passage 22b and improving the atomization efficiency of the atomized liquid.

[0161] It should be noted that the fifth air passage 22be can be directly connected to the nozzle 23, or it can be formed by the atomizing housing 22 to form the fourth air passage 22bd, so as to be indirectly connected to the nozzle 23 through the fourth air passage 22bd.

[0162] The cross-sectional area of ​​each airway 22b can be the same or different. For example, the cross-sectional area of ​​the fifth airway 22be is larger than that of the fourth airway 22bd and the third airway 22bc. This facilitates the connection between the airways 22b and improves the airflow efficiency of the airways 22b.

[0163] In one embodiment, the atomizer module 20 further includes a sealing ring, which is disposed at the connection between the adapter 222 and the atomizing bullet 221. When the adapter 222 and the atomizing bullet 221 form a liquid storage cavity 22a, the sealing ring is used to seal the cavity and prevent leakage of the atomizing liquid.

[0164] In one embodiment, referring to Figures 9 and 10, the atomizer module 20 includes a third seal 25, which is provided at the connection between the first ejector hole 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 ensuring the stability of the air pressure in the electronic atomizing device.

[0165] In one embodiment, referring to Figures 9 and 10, the atomizer module 20 includes a third seal 25, which is provided at the connection between the second ejector hole and the fifth air passage 22be. Thus, the third seal 25 seals the connection between the third air passage 22bc and the fifth air passage 22be, thereby ensuring the overall sealing of the air passage 22b and thus guaranteeing the stability of the air pressure in the electronic atomizing device.

[0166] In one embodiment, please refer to FIG10, one end of the second air passage 22bb has a third mold outlet hole, and the atomizer module 20 further includes a second seal 24 disposed at the third mold outlet hole, at least one of the second seal 24 and the third seal 25 being a soft rubber material.

[0167] Specifically, only the second seal 24 can be made of soft rubber material, only the third seal 25 can be made of soft rubber material, or both the second seal 24 and the third seal 25 can be made of soft rubber material. The soft rubber material can be appropriately deformed to adapt to different design and size requirements. Therefore, the second seal 24 and the third seal 25 can effectively seal the air passage 22b, thereby improving the sealing performance of the electronic atomizing device and thus improving atomization efficiency.

[0168] The type of material can be any soft material, such as sealing silicone.

[0169] In one embodiment, one end of the second air passage 22bb has a third ejector hole. The atomizer module 20 further includes a second seal 24 disposed at the third ejector hole. At least one of the second seal 24 and the third seal 25 has a hardness greater than or equal to Shore A40 and less than or equal to Shore A80. For example, the hardness of at least one of the second seal 24 and the third seal 25 is Shore A40, Shore A60, or Shore A80. Thus, by using a hardness within the above range, the second seal 24 and the third seal 25 can have good elasticity and structural strength, effectively filling and sealing the tiny gaps between the air passages 22b, thereby improving the sealing effect.

[0170] Specifically, the hardness of the second seal 24 may be greater than or equal to Shore A40 and less than or equal to Shore A80; the hardness of the third seal 25 may be greater than or equal to Shore A40 and less than or equal to Shore A80; or the hardness of both the second seal 24 and the third seal 25 may be greater than or equal to Shore A40 and less than or equal to Shore A80.

[0171] In one embodiment, referring to Figures 10 and 11, the atomizer module 20 further includes an atomizing cartridge top cover 223, a comb assembly 224, and a nozzle 23 seal. The liquid storage chamber 22a has a liquid outlet. The atomizing cartridge top cover 223 is located at the end of the adapter 222 opposite to the liquid storage chamber 22a. The comb assembly 224 is located on one side of the nozzle 23 outlet 23a. The nozzle 23 communicates with the liquid outlet of the liquid storage chamber 22a. The nozzle 23 seal is located at the connection between the nozzle 23 and the liquid outlet to prevent leakage of the atomized liquid from the outlet. This allows the electronic atomizing device to achieve better atomization.

[0172] In one embodiment, referring to Figures 1 and 13, the host module 10 includes an indicator light 17 and a control component 18. The host housing 16 has a receiving cavity 16a and a button port 16b. The receiving cavity 16a communicates with the outside through the button port 16b. The indicator light 17 is disposed in the receiving cavity 16a. The control component 18 includes a pressing member 181 and a control switch 182. The control switch 182 is disposed in the receiving cavity 16a and is electrically connected to the indicator light 17 and the power component 13, respectively. The pressing member 181 is disposed 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 component 13.

[0173] The end face of the pressing member 181 opposite to the receiving cavity 16a has a light-shielding area and a light-display area extending circumferentially around the light-shielding area. The light-display area is made of a light-transmitting material so that at least part of the light of the indicator light 17 can be emitted through the light-display area.

[0174] Specifically, the location of the button port 16b is not limited. For example, a portion of the side wall of the main unit casing 16 may be open to form the button port 16b. Or, a portion of the end face of the main unit casing 16 may be open to form the button port 16b.

[0175] The shape of the button port 16b is not limited. For example, the button port 16b can be round or square.

[0176] 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 seen through the light display area. For example, one indicator light 17 can be located at the bottom of the light display area. Or, multiple indicator lights 17 can be located at the bottom of the light display area.

[0177] It is understandable that the control switch 182, indicator light 17, and power supply assembly 13 can be electrically connected via wiring, or they can all be located on the circuit board 14 and electrically connected to the circuit board 14.

[0178] For example, the main module 10 also includes a circuit board 14, on which the control switch 182 and the indicator light 17 are located and electrically connected. Thus, by integrating the control switch 182 and the indicator light 17 onto the circuit board 14, internal space of the electronic atomizing device can be saved, facilitating the structural arrangement within the electronic atomizing device.

[0179] The press button 181 is a mechanical button structure for the user to press to turn the electronic atomizing device on or off. By pressing the press button 181, the user can make the press button 181 cooperate with the control switch 182 to control the indicator light 17 to turn on and off.

[0180] The control switch 182 controls the indicator light 17 to turn on and off by closing and opening the control circuit.

[0181] The structure of the control switch 182 is not limited, as long as it can control the closing and opening of the circuit.

[0182] For example, the control switch 182 includes a spring and a switch body, with the spring disposed within the switch body. When the user presses the pressing member 181, the pressing member 181 contacts the spring, thereby turning the indicator light 17 and the power assembly 13 on and off. The spring can generate a "clicking" sensation through elastic deformation, thus improving the user's tactile feedback.

[0183] The method of forming the light-shielding area is not limited. It can be formed by using an opaque material for a portion of the pressing member 181, or by using a light-shielding member 1815 to block a portion of the pressing member 181 to form the light-shielding area.

[0184] The shape of the light-shielding area is not limited, as long as it can block the light of indicator light 17. For example, the light-shielding area can be circular or square.

[0185] The material of the indicator area is not limited, as long as it allows the light from indicator light 17 to pass through. For example, the material of the indicator area can be silicone or PC.

[0186] It should be noted that the light-transmitting material refers to the material that allows some or all of the light from the indicator light 17 to pass through. It can be a fully transparent material or a semi-transparent material.

[0187] The lighting display area is arranged circumferentially around the shading area.

[0188] It should be noted that the specific shape of the light display area can be set according to the actual situation.

[0189] 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.

[0190] Of course, the light display area can also be arc-shaped or other shapes.

[0191] In related technologies, the lampshade of indicator light 17 and the push-button switch are respectively located in different positions of the electronic atomizing device, resulting in a complex structure. However, in this embodiment, the electronic atomizing device, by dividing the pressing member 181 into a light-shielding area and a light-display area, allows the pressing member 181 to not only control the power supply component 13 and the indicator light 17 to turn on and off under external force, but also to allow the light from the indicator light 17 to shine through. Thus, the pressing member 181 functions not only as a push-button switch but also as a lampshade. This greatly simplifies the internal structure of the electronic atomizing device, making it simpler and saving internal space. Furthermore, by circumferentially arranging the light-display area around the light-shielding area, more light from the indicator light 17 shines through the light-display area, resulting in a more uniform light transmission effect for the indicator light 17.

[0192] In one embodiment, referring to Figures 12 and 13, the pressing member 181 includes a pressing portion 1811 and a light-shielding member 1815. The pressing portion 1811 is disposed at the button opening 16b and is made of a light-transmitting material. The light-shielding member 1815 is made of a light-shielding material. A portion of the end face of the pressing portion 1811 facing away from the receiving 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 face of the pressing portion 1811 forms a light display area. This allows the light from the indicator light 17 to shine through the light display area, resulting in a more uniform light display. Simultaneously, it prevents the light-shielding member 1815 from falling off, improving its installation stability.

[0193] Specifically, the material of the pressing part 1811 is not limited, as long as it allows the light of the indicator light 17 to pass through.

[0194] For example, the material of the pressing part 1811 includes one of silicone, ABS (acrylonitrile butadiene styrene copolymer), or PC (polycarbonate).

[0195] For example, the material of the pressing part 1811 also includes light-diffusing powder, which can increase the transparency of the light display area of ​​the pressing part 1811, thereby enhancing the brightness of the light of the indicator light 17 when it passes through the light display area.

[0196] The material of the light shield 1815 is not limited, as long as it can prevent the light from the indicator light 17 from passing through.

[0197] The projected area of ​​the light-shielding member 1815 on the end face of the pressing part 1811 away from the receiving cavity 16a is the range of the light-shielding area, and the projected shape of the light-shielding member 1815 on the end face away from the receiving cavity 16a is the shape of the light-shielding area.

[0198] The light shield 1815 can prevent the light of the indicator light 17 from shining through the light shield area by absorbing or reflecting the light of the indicator light 17.

[0199] The shape of the recessed area is not limited. For example, the cross-sectional shape of the recessed area can be circular or square.

[0200] The light-shielding member 1815 is located in the recessed area and blocks 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 non-recessed part is the light display area of ​​the pressing member 181.

[0201] The depth of the recessed area can be the thickness of the light-shielding member 1815. This allows the end face of the light-shielding member 1815 away from the receiving cavity 16a to be flush with the end face of the lamp display area away from the receiving cavity 16a when the light-shielding member 1815 is located in the recessed area, thereby improving the surface flatness of the electronic atomizing device.

[0202] Of course, the depth of the recessed area can be greater than the thickness of the light-shielding part 1815, or the depth of the recessed area can be less than the thickness of the light-shielding part 1815.

[0203] In one embodiment, referring to Figure 13, the control switch 182 is located in the pressing direction of the pressing member 181. The main module 10 includes multiple indicator lights 17, which are spaced apart circumferentially around the control switch 182 on a plane perpendicular to the pressing direction. Therefore, by providing multiple indicator lights 17, the phenomenon of point light sources in the electronic atomizing device can be prevented, resulting in more uniform light display.

[0204] Specifically, the indicator lights 17 are spaced circumferentially around the control switch 182, which can cooperate with the light display area that extends circumferentially around the light shielding area, so that the light transmission effect of each area of ​​the light display area is better, and thus the light display is more uniform.

[0205] Multiple indicator lights 17 can be located on different planes or on the same plane.

[0206] For example, control switch 182 and indicator light 17 are both located on circuit board 14, electrically connected to circuit board 14, and arranged at intervals along the circumference of control switch 182.

[0207] The connection method between the control switch 182 and the circuit board 14 is not limited. For example, the control switch 182 can be fixed to the circuit board 14 by soldering.

[0208] In one embodiment, referring to Figure 13, at least one indicator light 17 is provided on each of the opposite sides of the control switch 182 along the fourth direction, and at least one indicator light 17 is provided on each of the opposite sides of the control switch 182 along the fifth direction, with the fourth and fifth directions being perpendicular. Therefore, by placing the indicator lights 17 on both sides of the control switch 182 in two mutually perpendicular directions, the lighting effect of the indicator lights 17 can be made more reliable.

[0209] Specifically, the number of indicator lights 17 provided on opposite sides of the control switch 182 along the fourth direction can be one or more.

[0210] The number of indicator lights 17 provided on opposite sides of the control switch 182 along the fifth direction can be one or more.

[0211] In one embodiment, referring to the figure, the pressing part 1811 is a lampshade. Thus, by integrating the lampshade and the button together, assembly is simplified and less space is required.

[0212] In one embodiment, referring to FIG13, the pressing part 1811 includes a first segment 1812 and a second segment 1813. The first segment 1812 is located inside the button opening 16b, and the second segment 1813 is located on the side of the first segment 1812 near the indicator light 17. The outer peripheral surface of the second segment 1813 protrudes relative to the outer peripheral surface of the first segment 1812 to form a limiting step, which abuts against the main unit housing 16. This prevents the pressing part 1811 from dislodging from the button opening 16b, thereby improving the installation stability of the pressing part 181.

[0213] Specifically, the outer peripheral surface of the second segment 1813 protrudes relative to the outer peripheral surface of the first segment 1812. That is, in a plane parallel to the end face of the first segment 1812, the cross-sectional area of ​​the second segment 1813 is larger than that of the first segment 1812, and also larger than the cross-sectional area of ​​the button opening 16b. Thus, the outer peripheral surfaces of the second segment 1813 and the first segment 1812 are stepped, thereby abutting against the main casing 16 at the button opening 16b to prevent the pressing part 1811 from dislodging from the button opening 16b.

[0214] The length of the second segment 1813 protruding from the outer periphery of the first segment 1812 is unlimited, as long as it can abut against the main unit casing 16 at the button port 16b.

[0215] The outer periphery of the second segment 1813 may protrude in a portion relative to the outer periphery of the first segment 1812 to abut against the main casing 16, or the entire outer periphery may protrude to abut against the main casing 16.

[0216] It should be noted that the first segment 1812 and the second segment 1813 of the pressing part 1811 can be separate structures. Depending on the actual situation, the first segment 1812 and the second segment 1813 of the pressing part 1811 can also be an integral structure, which can improve the structural stability of the pressing part 181.

[0217] In one embodiment, referring to Figure 13, the projection of the indicator light 17 is located within the projection range of the second segment 1813, parallel to the end face of the second segment 1813 near the indicator light 17. This allows for a more uniform light display of the indicator light 17, reduces the occurrence of point light sources, and thus makes the light display effect more reliable.

[0218] In other words, all indicator lights 17 are positioned within the coverage area of ​​the second segment 1813, allowing the light emitted by the indicator lights 17 to pass through the second segment 1813 more easily. From a projection perspective, the projection of the indicator lights 17 is located within the projection range of the second segment 1813.

[0219] It should be noted that the projection of indicator light 17 can be located within the projection range of the light display area for only a portion of the area, or the projection of the entire area can be located within the projection range of the light display area.

[0220] In one embodiment, the distance between the indicator light 17 and the second segment 1813 is greater than or equal to 3mm and less than or equal to 6mm, such as 3mm, 4mm, 5mm, or 6mm. This avoids the phenomenon of uneven light display 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.

[0221] In one embodiment, referring to FIG13, the pressing part 1811 further includes a pressing rod 1814. The pressing rod 1814 is disposed on the side of the second section 1813 near the indicator light 17. The control switch 182 is disposed on the side of the pressing rod 1814 away from the second section 1813 and is 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 external force, the indicator light 17 switches between on and off. Thus, by cooperating with the control switch 182, the pressing rod 1814 can switch the indicator light 17 between on and off.

[0222] Specifically, the second segment 1813 is located between the first segment 1812 and the pressing lever 1814. The control switch 182 is located on one side of the pressing lever 1814 along the pressing direction. Therefore, by pressing the pressing part 1811 with external force, the pressing lever 1814 can be brought into contact with the control switch 182 along the pressing direction, thereby turning the indicator light 17 on and off.

[0223] Under the action of external force, the first segment 1812 and the second segment 1813 can drive the pressing rod 1814 in any way.

[0224] For example, the first segment 1812 is located inside the button port 16b and can move relative to the button port 16b. Under the action of external force, the first segment 1812 moves towards the receiving cavity 16a, 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.

[0225] For example, the step formed by the first segment 1812 and the second segment 1813 is fixedly connected to the main unit housing 16. Under the action of external force, the main unit housing 16 undergoes elastic deformation, thereby driving the pressing rod 1814 to move, and then cooperating with the control switch 182 to switch the indicator light 17 between on and off.

[0226] In its natural state, without the action of external force, the end of the pressing lever 1814 near the indicator light 17 and the control switch 182 are separated by a gap to prevent accidental activation and change of the on or off state of the indicator light 17.

[0227] In one embodiment, referring to Figures 14 and 15, the atomizer module 20 includes a first one-way valve 27. The atomizing 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. The first one-way valve 27 is at least partially disposed in the liquid storage chamber 22a and is movably disposed at the connection between the liquid storage chamber 22a and the air hole 22e.

[0228] 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 vent 22e; when the first one-way valve 27 is in the conducting state, the first one-way valve 27 opens the vent 22e, so that external airflow enters the liquid storage chamber 22a through the vent 22e; the first one-way valve 27 switches between the blocking state and the conducting state by moving relative to the vent 22e.

[0229] Therefore, on the one hand, by setting the vent 22e, external airflow can easily enter the liquid storage chamber 22a through the vent 22e to balance the air pressure inside and outside the liquid storage chamber 22a, thus facilitating liquid dispensing. On the other hand, a first one-way valve 27 is set at the connection between the liquid storage chamber 22a and the vent 22e. When the first one-way valve 27 is in the blocked state, it can block the vent 22e, reducing the risk of the atomized liquid in the liquid storage chamber 22a flowing out of the vent 22e, thereby greatly improving the sealing effect in the liquid storage chamber 22a. Furthermore, when the first one-way valve 27 is in the open state, it can keep the vent 22e open, allowing external airflow to enter the liquid storage chamber 22a through the vent 22e, thereby replenishing the gas in the liquid storage chamber 22a. At the same time, it can also ensure smooth atomization at the nozzle 23, reducing the occurrence of undesirable phenomena such as intermittent misting, no misting, or atomization pulses caused by negative pressure in the liquid storage chamber 22a. Since the connection between the liquid storage chamber 22a and the air hole 22e is provided by the first one-way valve 27, which only has the function of introducing external airflow into the liquid storage chamber 22a when it is in the conducting state, it can further reduce 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, thus making the sealing effect better.

[0230] Specifically, the liquid channel 22d is a channel that connects the liquid storage chamber 22a and the nozzle 23 respectively, so as to allow 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.

[0231] The air hole 22e on the atomizing shell 22 is used to connect the liquid storage chamber 22a with the outside world, 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 liquid to flow into the atomized liquid in the liquid storage chamber 22a.

[0232] 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 when the valve is open.

[0233] Specifically, in the blocked state, the first one-way valve 27 blocks the vent 22e, preventing external airflow from entering the liquid storage chamber 22a through the vent 22e, and also preventing the atomized liquid in the liquid storage chamber 22a from flowing out through the vent 22e.

[0234] In the open state, the first one-way valve 27 opens the vent 22e. External airflow can enter the liquid storage chamber 22a through the vent 22e, while the atomized liquid in the liquid storage chamber 22a cannot flow out through the vent 22e.

[0235] It should be noted that the specific manner in which the first one-way valve 27 opens the vent 22e is not limited, as long as it can connect the vent 22e with the liquid storage chamber 22a so that external air can flow into the liquid storage chamber 22a.

[0236] For example, the first one-way valve 27 can be configured to completely avoid the vent 22e, allowing the vent 22e to be fully open for conduction. Alternatively, the first one-way valve 27 can be configured to partially avoid the vent 22e, allowing only a portion of the vent 22e to be open for conduction.

[0237] The first one-way valve 27 may be entirely located within the liquid storage chamber 22a, or it may be partially located within the liquid storage chamber 22a and partially located outside the liquid storage chamber 22a.

[0238] Furthermore, the first one-way valve 27 can be entirely located at the connection between the liquid storage chamber 22a and the vent 22e, and can be movable relative to the vent 22e. Alternatively, a portion of the valve can be located at the connection between the liquid storage chamber 22a and the vent 22e, and can be movable relative to the vent 22e.

[0239] The first one-way valve 27 can switch between a blocked state and a conducting state by moving relative to the vent 22e. The specific form of movement of the first one-way valve 27 relative to the vent 22e is not limited, such as rotation, translation, elastic deformation, sliding, etc.

[0240] It should be noted that the specific structure of the first one-way valve 27 is not limited. Depending on its structure, the way the first one-way valve 27 moves relative to the vent 22e will vary. For example, the first one-way valve 27 moves relative to the vent 22e under the influence of the pressure difference between the liquid storage chamber 22a and the outside. Switching the first one-way valve 27 by the pressure difference simplifies its specific structure while better meeting the need to replenish the liquid storage chamber 22a with external gas.

[0241] Of course, the first check valve 27 can also adopt other structural types, such as solenoid valves or other valve structures.

[0242] The material of the first check valve 27 can also be set according to the actual situation. For example, the material of the first check valve 27 can be one of silicone, aero-rubber, and fluorosilicone. This allows the first check valve 27 to have good elastic deformation ability and good sealing effect.

[0243] For example, the hardness of the first one-way valve 27 is greater than or equal to Shore A40 and less than or equal to Shore A80. Examples include Shore A40, Shore A60, and Shore A80. This allows the first one-way valve 27 to possess good hardness.

[0244] The dimensions of the first one-way valve 27 and the vent 22e can also be set according to the actual situation.

[0245] For example, the diameter of the region 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 dimensions include 6 mm, 8 mm, or 9 mm. These dimensions facilitate manufacturing and allow for compatibility with conventional liquid storage chambers 22a and vents 22e.

[0246] For example, the diameter of the vent 22e is greater than or equal to 0.5 mm and less than or equal to 1 mm. For instance, 0.5 mm, 0.8 mm, or 1 mm. Using these dimensions facilitates manufacturing and allows for compatibility with the conventional liquid storage chamber 22a and the first one-way valve 27.

[0247] In one embodiment, referring to FIG15, the atomizing housing 22 includes a mounting wall 225 having vents 22e. The mounting wall 225 has a first wall surface 225a located within the liquid storage chamber 22a. The first one-way valve 27 includes a first valve body 271 located within the liquid storage chamber 22a and separably attached to the first wall surface 225a. The vents 22e are located within the coverage area of ​​the first valve body 271, so that the first one-way valve 27 is in a blocked state.

[0248] When the electronic atomizing device is working, under the action of air pressure difference, a part of the first valve body 271 separates from the first wall surface 225a through elastic deformation, so that the first one-way valve 27 switches to the conducting state.

[0249] Specifically, the mounting wall 225 is the wall on the side of the atomizing housing 22 with the air hole 22e. The air hole 22e penetrates the mounting wall 225 so as to connect the liquid storage chamber 22a with the outside when the first one-way valve 27 does not block the air hole 22e.

[0250] In fact, the first valve body 271 is detachably attached to the wall region of the atomizing housing 22 located at the junction of the liquid storage chamber 22a and the vent 22e, and covers the vent 22e. Therefore, the coverage area and cross-sectional dimensions of the first valve body 271 are larger than the cross-sectional dimensions of the vent 22e.

[0251] Therefore, when the electronic atomizing device is working, the air compressor 11 supplies air to the nozzle 23 through the air passage 22b, creating a negative pressure (such as a negative pressure of -1KPa to -4KPa) in the liquid passage 22d, causing the atomized liquid inside the liquid storage chamber 22a to flow out. As the atomized liquid is gradually consumed, the negative pressure in the liquid storage chamber 22a gradually decreases, and the pressure difference between the liquid storage chamber 22a and the outside gradually increases. When the pressure difference reaches the set pressure range, the first one-way valve 27 switches to the open state, and a part of the first valve body 271 undergoes elastic deformation and separates from the first wall surface 225a, allowing the liquid storage chamber 22a to connect with the outside through the air hole 22e, thereby allowing external airflow to enter the liquid storage chamber 22a through the air hole 22e. This ensures smooth atomization at the nozzle 23 and reduces the occurrence of undesirable phenomena such as intermittent mist output, no mist output, or atomization pulses caused by the negative pressure in the liquid storage chamber 22a.

[0252] It should be noted that when the air pressure inside 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 separates the air hole 22e and the liquid storage chamber 22a by fitting against the first wall surface 225a. This achieves a good sealing effect.

[0253] The structural shape of the first valve body 271 can be set according to the actual situation.

[0254] For example, referring to Figures 15 and 16, the side of the first valve body 271 facing away from the vent 22e is a curved surface 271a. From the central region of the first valve body 271 to the circumferential edge, the curved surface 271a curves towards the side closer to the first wall surface 225a. That is, the side of the first valve body 271 facing away from the first wall surface 225a is a curved surface 271a, and it gradually curves from the center outwards towards the side closer to the first wall surface 225a. Thus, by forming the curved surface 271a, the sealing effect can be further enhanced.

[0255] Of course, in other embodiments, the side of the first valve body 271 away from the air hole 22e may also be inclined.

[0256] For example, the cross-sectional dimensions of the first valve body 271 gradually decrease from the central region to the circumferential edge. In other words, the first valve body 271 adopts a structure that gradually thins from the center outwards. Therefore, under the pressure difference between the inside and outside 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, allowing at least a portion of the circumferential edge to separate from the first wall surface 225a, thereby enabling the passage of the vent 22e.

[0257] The vent 22e is located within the coverage area of ​​the first valve body 271, and its specific position relative to the first valve body 271 can be set according to the actual situation.

[0258] For example, referring to Figure 16, the first valve body 271 includes a transition section 2711 located between the central region and the circumferential edge, with an air hole 22e located within the coverage of the transition section 2711, and the central region of the first valve body 271 fixed to the mounting wall 225.

[0259] In other words, the vent 22e is not directly positioned within the coverage area of ​​the central region, nor is it directly positioned within the coverage area of ​​the circumferential edge of the first valve body 271. Instead, it is positioned within the coverage area of ​​the transition section 2711 between the two. This facilitates the fixation of the central region of the first valve body 271 to the mounting wall 225, preventing the vent 22e from interfering with the installation of the first valve body 271. Furthermore, it avoids any impact on the sealing and waterproofing performance of the first valve body 271 due to the vent 22e being positioned at its circumferential edge.

[0260] In one embodiment, referring to FIG15, the first valve body 271 has a mating surface 271b that fits against the first wall surface 225a. The first one-way valve 27 further includes a positioning post 272 disposed on the mating surface 271b. The mounting wall 225 has a positioning hole that communicates with the liquid storage chamber 22a. The positioning post 272 passes through the positioning hole so that the air hole 22e is located within the coverage area of ​​the first valve body 271 by positioning and cooperating with the positioning hole.

[0261] Specifically, the positioning hole and the air hole 22e are offset from each other, so that the air hole 22e can avoid the positioning post 272.

[0262] Meanwhile, a positioning pin 272 is inserted into the positioning hole to position and engage with it. This facilitates the first valve body 271 covering the air hole 22e, making it easier to install the first check valve 27. It also ensures that the first valve body 271 is securely installed on the mounting wall 225, preventing misalignment.

[0263] It should be noted that the positioning post 272 is inserted into the positioning hole. The positioning post 272 can be detachably installed in the positioning hole or it can be non-detachably installed in the positioning hole.

[0264] For example, the positioning post 272 passes through the positioning hole and engages with the mounting wall 225.

[0265] For example, the positioning pin 272 is inserted into the positioning hole and threadedly connected to the mounting wall 225.

[0266] The end of the positioning hole away from the liquid storage cavity 22a can be a closed end or an open end that communicates with the outside.

[0267] For example, please refer to Figures 15 and 16. The end of the positioning hole away from the liquid storage cavity 22a is connected to the outside. The positioning post 272 is locked in the positioning hole and blocks the positioning hole. The end of the positioning post 272 away from the mating surface 271b extends out of the positioning hole to form the protruding end 2721.

[0268] Specifically, the positioning post 272 is inserted into the positioning hole to engage with the mounting wall 225 and to seal the positioning hole to prevent the atomized liquid in the liquid storage chamber 22a from flowing out through the positioning hole.

[0269] By extending the end of the positioning pin 272 away from the mating surface 271b out of the positioning hole, it is easier to pass the positioning pin 272 through the positioning hole so that the first check valve 27 can be installed on the mounting wall 225.

[0270] In one embodiment, referring to Figures 15 and 16, the mounting wall 225 has a second wall surface 225b facing away from the first wall surface 225a, and a portion of the protruding end 2721 protrudes to form a snap fastener 2722. The outer dimensions of the snap fastener 2722 are larger than the opening size of the positioning hole, and the snap fastener 2722 abuts against the second wall surface 225b.

[0271] Specifically, the second wall surface 225b is the side of the mounting wall 225 opposite to the first wall surface 225a, that is, the first wall surface 225a and the second wall surface 225b are the opposite sides of the mounting wall 225.

[0272] The end of the positioning post 272 facing away from the mating surface 271b has a protruding undercut 2722. In the area where the positioning hole is located on the second wall surface 225b, because the size of the undercut 2722 is larger than the opening size of the positioning hole, the undercut 2722 abuts against the second wall surface 225b, making it difficult for the undercut 2722 to pass through the positioning hole under the action of air pressure difference. Therefore, when the electronic atomizing device is working, under the action of air pressure difference, a part of the first valve body 271 separates from the first wall surface 225a through elastic deformation, allowing airflow to be replenished into the liquid storage chamber 22a through the air hole 22e. Since the undercut 2722 abuts against the second wall surface 225b, it can limit the first valve body 271. Thus, while a part of the first valve body 271 can be separated from the first wall surface 225a through elastic deformation, it will not completely detach from the first wall surface 225a due to air pressure difference. At the same time, when the electronic atomizing device stops working, it can also prevent the first one-way valve 27 from failing to switch back to the blocked state.

[0273] In one embodiment, the snap-fit ​​part 2722 is made of an elastically deformable material. During the installation of the first one-way valve 27, the snap-fit ​​part 2722 can elastically deform to pass through the positioning hole from the side of the liquid storage chamber 22a to abut against the second wall surface 225b. This facilitates better installation of the first one-way valve 27.

[0274] In one specific embodiment, during the installation of the first check valve 27, the protruding end 2721 enters the positioning hole from one side of the liquid storage chamber 22a. When the inverted part 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. The protruding end 2721 is pulled by hand or with a clamp, causing the inverted part 2722 to elastically deform and pass through the positioning hole until the positioning hole connects to the outside. At this point, the inverted part 2722 returns to its original shape, thus abutting against the second wall surface 225b. This effectively prevents the first check valve 27 from detaching, and the overall assembly is simple, efficient, and low-cost.

[0275] It should be noted that in some embodiments, the portion of the protruding end 2721 below the inverted position 2722 can be cut off to reduce the interference of the protruding end 2721 with other structures.

[0276] 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 an atomizing cartridge 221 body and an atomizing cartridge 221 adapter 222. The atomizing cartridge 221 body and the atomizing cartridge 221 adapter 222 enclose a liquid storage cavity 22a. An air hole 22e is located on the atomizing cartridge 221 adapter 222. The atomizing cartridge 221 is located inside the mounting cavity 12a, and the atomizing cartridge 221 adapter 222 is located on one side of the mounting inlet 12b. The top cover is provided at the mounting inlet 12b and has an opening communicating with the air hole 22e and the outside.

[0277] The atomizer module 20 may also include a comb assembly 224, which is located in the mounting cavity 12a and on the side of the atomizing bullet 221 body away from the atomizing bullet 221 adapter 222.

[0278] In one embodiment, referring to FIG18, the atomizer module 20 includes a sealing assembly 26, an atomizing housing 22 having a first liquid inlet 22c, a liquid storage chamber 22a communicating with the first liquid inlet 22c, and at least a portion of the sealing assembly 26 being movable relative to the first liquid inlet 22c to switch between a blocked state at the first liquid inlet 22c and an open state avoiding the first liquid inlet 22c; when the sealing assembly 26 is in the open state, the sealing assembly 26 is connected to the atomizing housing 22.

[0279] Therefore, on the one hand, the sealing component 26 can be prevented from being lost due to falling during the liquid filling process of the atomizer module 20. On the other hand, it can also prevent the sealing component 26 from being contaminated by falling to the ground during the liquid filling process, thereby minimizing the contamination of the atomizing liquid in the liquid storage chamber 22a by the sealing component 26 when sealing the liquid storage chamber 22a.

[0280] Specifically, the sealing assembly 26 can block the first injection port 22c that communicates with the liquid storage chamber 22a to prevent the atomized liquid from flowing out of the liquid storage chamber 22a from the first injection port 22c.

[0281] The atomized liquid in the reservoir 22a is transferred to the nozzle 23 and atomized under the action of the high-speed airflow provided by the air compressor 11 to generate an aerosol. At least a portion of the sealing assembly 26 is movable relative to the first injection port 22c to switch between a blocked state and an open state.

[0282] Depending on the actual situation, the sealing component 26 may be movable only in a portion of the area relative to the first injection port 22c, so as to switch between blocking the first injection port 22c and opening the first injection port 22c.

[0283] Similarly, the sealing assembly 26 can also be entirely movable relative to the first injection port 22c, switching between blocking the first injection port 22c and opening the first injection port 22c. Furthermore, when the sealing assembly 26 is entirely movable relative to the first injection port 22c, the sealing assembly 26 and the atomizing housing 22 remain connected.

[0284] In the blocked state, at least a portion of the sealing assembly 26 is located at the first injection port 22c to block the first injection port 22c. Thus, the sealing assembly 26 allows the atomizing liquid to remain in the reservoir 22a, preventing the atomizing liquid from flowing out of the first injection port 22c.

[0285] It should be noted that the sealing component 26 can block the first injection port 22c in any way.

[0286] For example, the sealing component 26 can slide relative to the first injection port 22c, and the sealing component 26 can be tightly fitted to the end face of the first injection port 22c to block the first injection port 22c.

[0287] For example, the sealing component 26 can also block the first injection port 22c by passing at least a portion of it through the first injection port 22c.

[0288] In the open state, at least a portion of the sealing assembly 26 is separated from the first injection port 22c to avoid the first injection port 22c, thereby allowing the liquid storage chamber 22a to communicate with the outside through the first injection port 22c. This facilitates the user injecting atomizing liquid into the liquid storage chamber 22a through the first injection port 22c.

[0289] It should be noted that, whether in the blocked state or the open state, the sealing component 26 is connected to the atomizing housing 22, thereby preventing the sealing component 26 from falling off.

[0290] Depending on the actual situation, the connection position between the sealing component 26 and the atomizing housing 22 is not limited.

[0291] For example, the sealing assembly 26 can be connected to the side of the atomizing housing 22 or to the end face of the atomizing housing 22 with the first liquid injection port 22c. The sealing assembly 26 and the atomizing housing 22 can be connected when the sealing assembly 26 is in the open state.

[0292] In one embodiment, referring to Figures 17 and 18, the sealing assembly 26 includes a first seal 261, a connector 262, and a fixing member 263. The fixing member 263 is fixed to the end face of the atomizing housing 22 having a first liquid injection port 22c. The connector 262 is connected to both the first seal 261 and the fixing member 263. The first seal 261 is movably disposed at the first liquid injection port 22c. Therefore, by fixing the fixing member 263 to the atomizing body 201 and connecting the fixing member 263 and the first seal 261 via the connector 262, the first seal 261 can be prevented from falling off when the sealing assembly 26 is in the open state, thereby preventing the loss of the first seal 261 or contamination of the atomizing liquid in the liquid storage chamber 22a.

[0293] Specifically, the fixing member 263 and the first liquid injection port 22c are located on the same end face of the atomizing housing 22.

[0294] The specific structure of the first seal 261 is not limited. For example, the first seal 261 is a sealing plug.

[0295] The specific shape and size of the first seal 261 are not limited.

[0296] For example, the first seal 261 is circular.

[0297] For example, the diameter of the first seal 261 is 4mm to 6mm.

[0298] The specific material and structure of the connector 262 are not limited, as long as it can connect the first seal 261 and the fixing member 263 to prevent the first seal 261 from falling off when the sealing assembly 26 is in the open state.

[0299] For example, connector 262 is made of an elastic material, such as silicone or rubber. This allows connector 262 to have a certain degree of deformability, enabling it to better seal the first injection port 22c.

[0300] For example, the hardness of connector 262 is greater than or equal to Shore A40 and less than or equal to Shore A85. For instance, the hardness of connector 262 may be Shore A40, Shore A70, or Shore A85. This prevents connector 262 from softening and deforming due to excessively low hardness, thus slowing down its wear rate. Conversely, it also prevents connector 262 from breaking due to poor elastic deformation caused by excessively high hardness.

[0301] By providing the connector 262, it is easy to place the fixing member 263 in other areas of the end face of the atomizing body 201. As a result, during the process of the user injecting liquid into the liquid storage chamber 22a from the first injection port 22c using the injection device, the interference of the sealing assembly 26 on the injection process can be reduced.

[0302] The specific position of the fixing component 263 on the end face of the atomizing body 201 is not limited.

[0303] For example, referring to Figures 17 and 18, a second air inlet 20a is also formed on the end face of the atomizing housing 22 with the first liquid injection port 22c. The air compressor 11 is connected to the air passage 22b through the second air inlet 20a. The first liquid injection port 22c and the fixing member 263 are respectively located on opposite sides of the second air inlet 20a. The connecting member 262 is bent in at least a partial area to avoid the second air inlet 20a when the sealing assembly 26 is in a blocked state. Thus, when liquid is injected into the liquid storage chamber 22a, the sealing assembly 26 can avoid the first liquid injection port 22c, making liquid injection more convenient and smooth.

[0304] Specifically, the first injection port 22c and the fixing member 263 are located on opposite sides of the second air inlet 20a, which enables the first sealing member 261 to avoid the first injection port 22c to a large extent when the sealing assembly 26 is in the open state, so as to further reduce the interference of the sealing assembly 26 on the injection process.

[0305] The first seal 261 avoids the first injection port 22c, meaning that when the sealing assembly 26 is in the open state, the first seal 261 does not block the first injection port 22c, so as to facilitate the injection of liquid into the liquid storage chamber 22a.

[0306] The connector 262 may be partially or entirely bent, as long as it allows the connector 262 to avoid the second air inlet 20a when the sealing assembly 26 is in the blocking state.

[0307] For example, connector 262 is an arc-shaped connecting arm.

[0308] It should be noted that the second air inlet 20a is the airflow inlet for airflow to enter the atomizer module 20. Depending on the specific type of atomizer module 20, the function of the airflow flowing into the atomizer module 20 from the second air inlet 20a varies.

[0309] For example, the air compressor 11 supplies high-speed airflow to the nozzle 23 through the second air inlet 20a. The nozzle 23 is connected to both the second air inlet 20a and the liquid storage chamber 22a, so that the airflow from the air compressor 11 atomizes the atomizing liquid in the liquid storage chamber 22a to generate an aerosol, and then supplies the aerosol to the outside of the atomizer module 20. In other words, the airflow flowing into the atomizing body 201 from the second air inlet 20a can atomize the atomizing liquid through high-speed flow and form an aerosol together, while also allowing the aerosol to flow out of the atomizer module 20.

[0310] In other embodiments, the electronic atomizing device can also atomize the atomizing liquid through an atomizing component disposed in the atomizing body 201. The airflow flowing in from the second air inlet 20a only serves to mix with the atomized liquid to form an aerosol and carry it out of the atomizer module 20.

[0311] The specific dimensions of connector 262 can also be set according to the actual situation.

[0312] 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, while also reducing the risk of damage to the connector 262 due to its small width.

[0313] 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, while reducing the risk of damage due to its thinness.

[0314] In one embodiment, referring to FIG19, the first sealing member 261 includes a second abutment portion 2611 and a sealing portion 2612. When the sealing assembly 26 is in a blocked state, the sealing portion 2612 is at least partially inserted into the first injection port 22c to seal against it. The second abutment portion 2611 is located outside the first injection port 22c and is connected to the connector 262. At the junction of the second abutment portion 2611 and the sealing portion 2612, the second abutment portion 2611 has an abutment surface 121a that abuts against the outer end face of the first injection port 22c. By inserting the sealing portion 2612 into the first injection port 22c, the first injection port 22c can be blocked. On the other hand, by abutting the second contact portion 2611 against the first injection port 22c, the risk of the first seal 261 completely entering the liquid storage chamber 22a due to improper operation can be reduced when the sealing portion 2612 blocks the first injection port 22c.

[0315] Specifically, the sealing part 2612 may be partially located in the first injection port 22c, so as to seal the first injection port 22c by sealing with the first injection port 22c.

[0316] The sealing part 2612 may also be entirely located in the first injection port 22c, so as to seal the first injection port 22c by sealing with the first injection port 22c.

[0317] The sealing method between the sealing part 2612 and the first injection port 22c is not limited.

[0318] For example, the sealing part 2612 has an external thread on its side wall, and the first injection port 22c has an internal thread that mates with the external thread. The sealing part 2612 passes through the first injection port 22c, and by rotating, the external thread and the internal thread are tightly engaged to seal the first injection port 22c.

[0319] It should be noted that the second contact part 2611 and the sealing part 2612 can be integrally formed or separately formed.

[0320] Furthermore, the connection method between the second abutment portion 2611 and the connector 262 is not limited.

[0321] For example, the second abutment portion 2611 is fixedly connected to the connector 262.

[0322] For example, the second abutment portion 2611 is movably connected to the connector 262, and the second abutment portion 2611 can rotate freely at the connection point with the connector 262.

[0323] It is understandable that the size of the contact surface 121a is larger than the size of the outer end face of the first injection port 22c, so that when the sealing assembly 26 is in the blocking state, the second contact part 2611 abuts against the outer end face of the first injection port 22c.

[0324] For example, the outer end face of the first injection port 22c is circular with a diameter of 4mm, and the abutment surface 121a is also circular with a diameter of 5mm to 8mm, thereby enabling the second abutment part 2611 to abut against the outer end face of the first injection port 22c.

[0325] In one embodiment, referring to FIG19, a first seal 261 is detachably disposed at the first injection port 22c. A portion of the outer surface of the first seal 261 protrudes to form a sealing protrusion 2613 extending circumferentially along the first seal 261. When the sealing assembly 26 is in a blocking state, the sealing protrusion 2613 is located in the first injection port 22c to form an interference fit with the inner wall of the first injection port 22c. Thus, by interfering with the inner wall of the first injection port 22c, the sealing protrusion 2613 can achieve a better blocking effect on the first injection port 22c.

[0326] Specifically, the sealing protrusion 2613 is arranged along the circumference of the first sealing member 261, and the sealing protrusion 2613 is located in the area where the first sealing member 261 and the inner wall of the first injection port 22c are sealed together.

[0327] The number of sealing protrusions 2613 is unlimited. The outer surface of the first seal 261 may have only one sealing protrusion 2613. Depending on the actual situation, the outer surface of the first seal 261 may have multiple sealing protrusions 2613, and the sealing protrusions 2613 are spaced apart along the axial direction of the first seal 261.

[0328] The sealing protrusion 2613 has a certain deformation capacity. When the user uses the first sealing element 261 to seal the first liquid injection port 22c, the sealing protrusion 2613 can be squeezed and deformed, so that after the first sealing element 261 is inserted into the first liquid injection port 22c, it fits the inner wall of the first liquid injection port 22c with an interference fit, thereby further improving the sealing effect.

[0329] In one embodiment, referring to FIG19, a portion of the outer peripheral surface of the second abutment portion 2611 is recessed to form a force-applying groove 261a. Thus, by providing the groove, the user can easily apply force during the process of pulling out the first seal 261, so as to facilitate the user separating the first seal 261 from the first injection port 22c.

[0330] Specifically, the outer peripheral surface of the second contact portion 2611 may be partially recessed to form a force-applying groove 261a, or it may be recessed circumferentially along the outer peripheral surface to form a force-applying groove 261a.

[0331] The number of force-applying grooves 261a is unlimited. For example, there may be one or more force-applying grooves 261a.

[0332] The force-applying groove 261a refers to the recessed area on the outer peripheral surface of the abutment surface 121a, which facilitates the application of force when the sealing part 2612 is pulled out from the first injection port 22c, so that the sealing assembly 26 changes from the blocked state to the open state.

[0333] In one embodiment, referring to Figures 20 and 21, one of the atomizer module 20 and the main unit module 10 includes a first snap-fit ​​portion 21, and the other includes a second snap-fit ​​portion 161.

[0334] The first latching part 21 has a first connecting slot 21a with an opening. The second latching part 161 is slidably disposed in the first connecting slot 21a through the opening and latches with the first latching part 21, so that the atomizer module 20 and the main unit module 10 can be detachably connected.

[0335] Therefore, on the one hand, by sliding the second engaging portion 161 within the first connecting slot 21a and engaging with it, 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 into the first connecting slot 21a from the opening, enabling the assembly of 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 from the opening, enabling the separation of the atomizer module 20 and the main unit module 10, thus further improving the ease of assembly and disassembly between the atomizer module 20 and the main unit module 10.

[0336] Specifically, the main unit module 10 is the main unit of the electronic atomizing device, and its specific structure is not limited.

[0337] For example, the main unit module 10 also includes a control component 18, and the power supply component 13 is electrically connected to the control component 18. The control component 18 controls the power supply component 13 circuit to control the opening and closing of the electronic atomizing device.

[0338] By sliding the second snap-fit ​​part 161 from the opening into the first connecting slot 21a, the first snap-fit ​​part 21 and the second snap-fit ​​part 161 can be snapped together, thereby realizing the assembly of the atomizer module 20 and the main unit module 10.

[0339] Meanwhile, the second latching part 161 in the first connecting slot 21a can slide out from the opening, thereby separating the first latching part 21 and the second latching part 161, thus realizing the separation of the atomizer module 20 and the main unit module 10.

[0340] The opening position of the first connecting slot 21a is not limited. Depending on the actual situation, a portion of the end of the first connecting slot 21a may be open to form an opening, or a portion of the slot wall of the first connecting slot 21a near the atomizer module 20 may be open to form an opening.

[0341] It should be noted that, depending on the specific structure of the main unit module 10 and the atomizer module 20, the way the second locking part 161 slides between the main unit module 10 and the atomizer module 20 through relative movement is different.

[0342] For example, the main unit module 10 and the atomizer module 20 can be connected by relative rotation, which allows the second locking part 161 to slide into and out of the first connecting slot 21a, thereby enabling the assembly and disassembly of the main unit module 10 and the atomizer module 20.

[0343] For example, the main unit module 10 and the atomizer module 20 can be connected by relative translation, allowing the second latching part 161 to slide into and out of the first connecting slot 21a, thereby enabling the assembly and disassembly of the main unit module 10 and the atomizer module 20.

[0344] The specific positions of the first latching part 21 and the second latching part 161 are set according to the actual situation.

[0345] For example, the main unit module 10 includes a first snap-fit ​​portion 21, and the atomizer module 20 includes a second snap-fit ​​portion 161.

[0346] For example, the main unit module 10 includes a second latching portion 161, and the atomizer module 20 includes a first latching portion 21.

[0347] For example, the atomizer module 20 includes a first snap-fit ​​portion 21, the main unit module 10 includes a main unit housing 16, the main unit housing 16 includes a second snap-fit ​​portion 161 at one end near the atomizing housing 22, the first snap-fit ​​portion 21 is disposed on the end face of the atomizing housing 22 near the main unit module 10, and the first connecting slot 21a extends circumferentially along the end face of the atomizing housing 22.

[0348] Specifically, the atomizing housing 22 can store atomizing liquid so that the atomizing liquid can be atomized to generate an aerosol.

[0349] The second connector 161 can be located at the port of the main unit housing 16 near the atomizer module 20, or it can be at a certain distance from the port.

[0350] By setting the first snap-fit ​​part 21 on the end face of the atomizing housing 22 and setting the second snap-fit ​​part 161 on one end of the main unit housing 16, it is easy to connect the first snap-fit ​​part 21 and the second snap-fit ​​part 161 so as to install the atomizing housing 22 onto the main unit housing 16.

[0351] Meanwhile, since the first connecting slot 21a extends circumferentially along the end face of the atomizing housing 22, the main unit module 10 and the atomizer module 20 can rotate relative to each other, so that the second locking part 161 can slide relative to the first connecting slot 21a, thereby realizing the assembly and disassembly between the main unit module 10 and the atomizer module 20.

[0352] The specific structural forms of the first latching part 21 and the second latching part 161 can be set according to the actual situation.

[0353] In one embodiment, referring to Figures 20 and 21, a portion of the outer wall of the first latching portion 21 is recessed to form a first connecting groove 21a. This facilitates the manufacturing of the first latching portion 21 and also reduces the weight of the electronic atomizing device.

[0354] Of course, in other embodiments, the first connecting slot 21a may also be formed by a portion of the outer side wall of the first latching portion 21 protruding to enclose it.

[0355] In one embodiment, referring to FIG21, the main housing 16 has a port at one end near the atomizing housing 22. At the port, a portion of the inner wall of the main housing 16 extends into the port to form a second snap-fit ​​portion 161.

[0356] It is understandable that a portion of the inner wall of the main unit casing 16 extends into the port, which may form a protrusion, the length of which is less than the extension length of the first connection slot 21a.

[0357] Of course, the inner wall of the main unit casing 16 can also be formed with raised strips, the length of which is equal to the extension length of the first connecting slot 21a. This can greatly improve the connection stability between the main unit module 10 and the atomizer module 20.

[0358] Of course, the second snap-fit ​​part 161 can also adopt other structural forms, as long as the second snap-fit ​​part 161 can enter the first connecting slot 21a through the opening of the first snap-fit ​​part 21 and then snap-fit ​​with the first snap-fit ​​part 21.

[0359] In one specific embodiment, the first snap-fit ​​part 21 is an arc-shaped plate, the first connecting slot 21a is an arc-shaped groove, and the second snap-fit ​​part 161 is an arc-shaped protrusion corresponding to the arc-shaped groove.

[0360] In one embodiment, referring to FIG20, the atomizer module 20 includes a plurality of first latching portions 21, each of the first latching portions 21 being spaced apart on the end face of the atomizing housing 22, and the main unit housing 16 includes a plurality of second latching portions 161, each of the second latching portions 161 corresponding to the first latching portions 21.

[0361] Specifically, the number of first latching parts 21 is the same as the number of second latching parts 161, such as 2 or 3. By setting multiple first latching parts 21 to be latched one-to-one with multiple second latching parts 161, the connection between the main unit module 10 and the atomizer module 20 can be made more stable.

[0362] It is understandable that the first latching part 21 is circumferentially spaced along the end face of the atomizing housing 22, and the second latching part 161 is circumferentially spaced along the inner wall of the main unit housing 16 near the atomizing housing 22. The second latching part 161 is placed at the interval of the first latching part 21 and slides into the first connecting slot 21a from the opening of the first latching part 21 by relative rotation, thereby realizing the assembly between the atomizer module 20 and the main unit module 10.

[0363] In one embodiment, referring to Figures 22 and 23, the first connecting slot 21a includes a snap-fit ​​end 21ab and a first open end 21aa with an opening. When the second snap-fit ​​part 161 slides from the first open end 21aa to the snap-fit ​​end 21ab, the opposite sides of the second snap-fit ​​part 161 respectively fit against the groove wall of the first connecting slot 21a. Therefore, the atomizer module 20 and the main unit module 10 are locked together and will not loosen.

[0364] Specifically, the first open end 21aa and the snap-fit ​​end 21ab are located at opposite ends of the first connecting slot 21a, and the second snap-fit ​​part 161 slides from the first open end 21aa to the snap-fit ​​end 21ab. When the second snap-fit ​​part 161 slides to the snap-fit ​​end 21ab, the second snap-fit ​​part 161 fits against the groove wall of the first connecting slot 21a, thereby achieving snap-fit.

[0365] It should be noted that, depending on the specific shape of the second snap-fit ​​part 161, after the second snap-fit ​​part 161 slides to the snap-fit ​​end 21ab, the second snap-fit ​​part 161 may only snap onto a portion of the groove wall of the first connecting slot 21a.

[0366] For example, the second engaging part 161 is a protrusion with a length shorter than the first connecting slot 21a. After the second engaging part 161 slides to the engaging end 21ab, the second engaging part 161 engages only with the slot wall of the engaging end 21ab.

[0367] For example, the second engaging part 161 is a protrusion with a length greater than or equal to that of the first connecting groove 21a. After the second engaging part 161 slides to the engaging end 21ab, the second engaging part 161 engages with the groove wall of the first connecting groove 21a for the entire length of the groove (i.e., the groove wall from the first opening end 21aa to the engaging end 21ab).

[0368] It should be noted that the two opposite sides of the second snap-fit ​​portion 161 can be completely fitted with the groove wall of the first connecting groove 21a. Alternatively, there can be small gaps in some areas, while other areas are tightly fitted. Or, the two opposite sides of the second snap-fit ​​portion 161 can be interference-fitted with the groove wall of the first connecting groove 21a.

[0369] In one embodiment, referring to FIG22, the cross-sectional area of ​​the first connecting groove 21a gradually decreases from the first opening end 21aa to the snap-fit ​​end 21ab. This allows the snap-fit ​​process between the atomizer module 20 and the main unit module 10 to be a gradual snap-fit ​​process, thereby ensuring the efficient and convenient engagement of the first snap-fit ​​part 21 and the second snap-fit ​​part 161, as well as the reliability of the functional implementation.

[0370] Specifically, the distance between the sidewalls of the first connecting slot 21aa and the snap-fit ​​end 21ab gradually decreases from the first opening end 21aa to the snap-fit ​​end 21ab. During the snap-fit ​​process between the atomizer module 20 and the main unit module 10, initially, the gap between the opposite sides of the second snap-fit ​​part 161 and the groove wall of the first connecting slot 21a is relatively large. As the second snap-fit ​​part 161 slides towards the snap-fit ​​end 21ab, the gap between the opposite sides of the second snap-fit ​​part 161 and the groove wall of the first connecting slot 21a gradually decreases until the second snap-fit ​​part 161 snaps into contact with the snap-fit ​​end 21ab, at which point the opposite sides of the second snap-fit ​​part 161 are in close contact with the groove wall of the first connecting slot 21a. This facilitates the sliding of the second snap-fit ​​part 161 from the first opening end 21aa to the snap-fit ​​end 21ab, while also enabling it to gradually snap into contact with the first connecting slot 21a.

[0371] Meanwhile, since the distance between the sidewalls of the first connecting slot 21a gradually increases from the snap-fit ​​end 21ab to the first opening end 21aa, it is also convenient to remove the second snap-fit ​​part 161 from the first connecting slot 21a.

[0372] The method of gradually decreasing cross-sectional area of ​​the first connecting slot 21a is not limited.

[0373] For example, the first connection slot 21a includes an inclined groove wall 211 on the side near the host module 10, extending from the first opening end 21aa to the snap-fit ​​end 21ab, with the inclined groove wall 211 inclined inwards towards the first connection slot 21a. Thus, by making the groove wall of the first connection slot 21a inclined on the side near the host module 10, the cross-sectional area of ​​the first connection slot 21a can be gradually reduced.

[0374] It should be noted that the groove wall of the first connecting card slot 21a on the side away from the host module 10 can be horizontal, or it can be inclined towards the first connecting card slot 21a from the first opening end 21aa to the card receiving end 21ab.

[0375] Specifically, the angle at which the inclined groove wall 211 is inclined toward the first connecting slot 21a is set according to the actual situation.

[0376] For example, the angle between the inclined groove wall 211 and the end face of the atomizing housing 22 is greater than 0° and less than or equal to 2°. For instance, the angle between the inclined groove wall 211 and the end face of the atomizing housing 22 is 1°, 1.5°, or 2°. This avoids the second locking portion 161 from easily sliding out of the first connecting groove 21a due to an excessively large angle between the inclined groove wall 211 and the end face of the atomizing housing 22.

[0377] In one embodiment, the main unit module 10 and the atomizer module 20 rotate relative to each other, causing the second latching portion 161 to slide from the first opening end 21aa to the latching 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 avoids the rotation angle being too small, resulting in a small latching range between the second latching portion 161 and the first connecting slot 21a, making it easy for the main unit module 10 and the atomizer module 20 to detach during connection. On the other hand, this avoids the rotation angle being too large, which would make it difficult for the second latching portion 161 to enter the slot through the opening of the first connecting slot 21a, making it difficult to assemble and disassemble the main unit module 10 and the atomizer module 20.

[0378] Specifically, the rotation method of the main unit module 10 and the atomizer module 20 is not limited, as long as the second locking part 161 can slide from the first opening end 21aa to the locking end 21ab to achieve locking.

[0379] Depending on the actual situation, the main module 10 can remain stationary while the atomizer module 20 rotates relative to the main module 10; the atomizer module 20 can remain stationary while the main module 10 rotates relative to the atomizer module 20; or the atomizer module 20 and the main module 10 can rotate simultaneously.

[0380] In one embodiment, referring to FIG23, a limiting protrusion 212 is formed on one of the groove wall of the first connecting slot 21a and the outer surface of the second engaging portion 161, and a limiting groove 21b is formed on the other. When the second engaging portion 161 is located at the engaging end 21ab, the limiting protrusion 212 is located within the limiting groove 21b. Thus, when the second engaging portion 161 is located at the engaging end 21ab, placing the limiting protrusion 212 within the limiting groove 21b allows for a tighter connection between the atomizer module 20 and the main unit module 10.

[0381] Specifically, the groove wall of the first connecting slot 21a may form a limiting protrusion 212, and the outer surface of the second locking part 161 may form a limiting groove 21b.

[0382] Alternatively, the groove wall of the first connecting slot 21a may form a limiting groove 21b, and the outer surface of the second locking part 161 may form a limiting protrusion 212.

[0383] The number of limiting protrusions 212 and limiting grooves 21b is unlimited, as long as the second snap-fit ​​part 161 is located at the snap-fit ​​end 21ab and the limiting protrusions 212 are located within the limiting grooves 21b.

[0384] For example, the number of limiting protrusions 212 is one or more, and the multiple limiting protrusions 212 are distributed at intervals. The number of limiting grooves 21b is also one or more, and the multiple limiting grooves 21b are distributed at intervals.

[0385] In one embodiment, referring 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 and the second air inlet 20a are connected. On one hand, after the main unit module 10 and the atomizer module 20 are snapped together, the air compressor 11 and the second air inlet 20a are connected, which can give the electronic atomization device a good gas sealing effect. On the other hand, the air compressor 11 supplies air to the atomizer module 20 to atomize the atomizing liquid in the atomizer module 20, thereby realizing the atomization function.

[0386] In one embodiment, referring to Figures 1, 28, 29 and 30, the atomizer module 20 includes an atomizing body 201, a dust cover 28 and a fourth seal 29.

[0387] 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 which 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.

[0388] The fourth seal 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 seal 29 to switch between blocking the mist outlet 23a and avoiding the mist outlet 23a.

[0389] Therefore, on the one hand, by sealing the nozzle 23 of the atomizer module 20 with the fourth sealing element 29, the leakage of atomizing liquid from the outlet 23a into the air can be effectively prevented, avoiding crystallization of the atomizing liquid due to exposure, which would then clog the nozzle 23. This ensures that the atomizing liquid maintains an appropriate atomization volume during the atomization process, preventing a reduction in atomization effect or complete failure to atomize due to crystallization and clogging, thus guaranteeing the continuous and stable function of the atomizer module 20. At the same time, it also prevents outside air from entering the liquid storage chamber 22a through the outlet 23a, thereby preventing contamination of the atomizing liquid. On the other hand, by connecting the fourth sealing element 29 to the dust cover 28, the fourth sealing element 29 can move synchronously with the movement of the dust cover 28 relative to the atomizing housing 22, thereby more effectively sealing or avoiding the outlet 23a.

[0390] 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 element 29 inside the dust cover 28 blocks the mist outlet 23a of the nozzle 23 of the atomizing body 201.

[0391] The connection method between the dust cover 28 and the atomizing housing 22 is not limited. For example, the dust cover 28 and the atomizing housing 22 can be connected by a snap-fit. Or, the dust cover 28 and the atomizing housing 22 can be connected by a thread.

[0392] The location of the fourth seal 29 within the mounting space 28a of the dust cover 28 is not limited. For example, the fourth seal 29 may be located on the side wall of the dust cover 28. Alternatively, the fourth seal 29 may be located on the inner wall of the dust cover 28 on the side opposite to the mounting inlet 12b.

[0393] The connection method between the fourth seal 29 and the dust cover 28 is not limited.

[0394] For example, the fourth seal 29 is detachably snapped into the mounting space 28a of the dust cover 28.

[0395] For example, the fourth seal 29 is glued to the installation space 28a of the dust cover 28 to fix it to the dust cover 28.

[0396] The material of the fourth seal 29 is not limited, as long as it can seal the mist outlet 23a when the dust cover 28 is connected to the atomizing housing 22. For example, the fourth seal 29 is an elastic element.

[0397] When the user installs the dust cover 28 on the atomizing housing 22, the fourth seal 29 can block the mist outlet 23a of the nozzle 23. When the user removes the dust cover 28 from the atomizing housing 22, the fourth seal 29 can separate from the nozzle 23, thereby avoiding the mist outlet 23a.

[0398] In one embodiment, referring 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 and form a receiving space 41b. A fourth seal 29 is disposed within the receiving space 41b. Therefore, installing the fourth seal 29 within the receiving space 41b provides installation stability for the fourth seal 29, and simultaneously ensures that the fourth seal 29 accurately seals the mist outlet 23a of the nozzle 23 when the dust cover 28 is connected to the atomizing housing 22.

[0399] Specifically, the dust cover wall 281 refers to the area on the dust cover 28 opposite to the side of the installation inlet 12b.

[0400] A portion of the wall surface of the dust cover 281 within the receiving cavity 16a extends toward the installation inlet 12b, forming a receiving space 41b for placing the fourth seal 29.

[0401] It is understandable that the shape of the area extending from the inner wall of the dust cover 281 toward the installation inlet 12b is not limited, as long as it can form a receiving space 41b and cooperate with the fourth seal 29 so that the fourth seal 29 is installed in the receiving space 41b.

[0402] For example, the annular region of the inner wall of the dust cover 281 extends toward the installation inlet 12b to form an annular receiving space 41b.

[0403] For example, multiple areas of the inner wall of the dust cover 281 extend at intervals toward the installation inlet 12b to form a receiving space 41b.

[0404] The manner in which the fourth seal 29 is disposed in the receiving space 41b is not limited.

[0405] For example, the side wall 283 of the receiving space 41b has a connecting snap 284 that mates with the fourth seal 29, the fourth seal 29 and the connecting snap 284 mate with each other to be installed in the receiving space 41b.

[0406] For example, the fourth seal 29 is installed in the receiving space 41b by interference fit with the side wall 283 of the receiving space 41b.

[0407] In one embodiment, referring to FIG28, the inner wall surface of the dust cover wall 281 includes a mounting wall surface and a side wall surface 283 located within the receiving space 41b. The mounting wall surface is located on the side of the receiving space 41b opposite to the mounting inlet 12b. A portion of the mounting wall surface protrudes towards the nozzle 23 to form a protrusion 282. At least a portion of the protrusion 282 and the side wall surface 283 are spaced apart to form a receiving groove 281a. One end of the fourth seal 29 opposite to the nozzle 23 is engaged in the receiving groove 281a for detachable connection with the dust cover 28. Thus, by engaging the fourth seal 29 with the receiving groove 281a, the connection between the fourth seal 29 and the dust cover 28 can be made more reliable.

[0408] It is understandable that, since a portion of the inner wall of the dust cover wall 281 extends to form a receiving space 41b, the receiving space 41b has an mounting wall and a side wall 283, that is, the mounting wall and the side wall 283 are both part of the inner wall.

[0409] Specifically, the mounting wall is located on the side of the accommodating space 41b away from the mounting entrance 12b, that is, the mounting wall is set opposite to the mounting entrance 12b.

[0410] The mounting wall can be a protrusion 282 protruding from the central region, with the outer peripheral surface of the protrusion 282 spaced from the side wall 283, thus forming a receiving groove 281a. Alternatively, the protrusion 282 can be attached to the side wall 283 on one side and spaced from the side wall 283 on the other side, thus forming a receiving groove 281a.

[0411] The shape and size of the fourth seal 29 are set according to the shape and size of the receiving groove 281a to ensure that the fourth seal 29 can be well locked in the receiving groove 281a and the atomizer module 20 will not fall out of the receiving groove 281a during use.

[0412] The specific manner in which the fourth seal 29 is engaged in the receiving groove 281a is not limited.

[0413] For example, the fourth seal 29 is provided with a snap or protrusion so that it can be snapped into the receiving groove 281a, thereby fixing the fourth seal 29 to the receiving groove 281a.

[0414] For example, when the fourth seal 29 is made of an elastic material, the fourth seal 29 can be pressed into the receiving groove 281a by pressure, thereby fixing the fourth seal 29 to the receiving groove 281a.

[0415] In one embodiment, referring to FIG28, the outer peripheral surface of the protrusion 282 and the side wall surface 283 are spaced apart. The receiving groove 281a is an annular groove. The fourth seal 29 has a receiving cavity 16a. The end of the receiving cavity 16a opposite to the nozzle 23 is open, so that the fourth seal 29 forms a second open end 291. The end of the receiving cavity 16a near the nozzle 23 is sealed, so that the fourth seal 29 forms a sealed end 292. The second open end 291 is engaged in the receiving groove 281a. Thus, by engaging 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 can be made more secure.

[0416] Specifically, the fourth seal 29 is connected to the receiving groove 281a through the second open end 291, and seals the nozzle 23 through the sealing end 292 when the dust cover 28 is connected to the atomizing housing 22.

[0417] The shape of the protrusion 282 is not limited, as long as the outer peripheral surface of the protrusion 282 can mate with the side wall surface 283 to form a receiving groove 281a. For example, the protrusion 282 can be cylindrical. Or, the protrusion 282 can be conical, mate with the side wall surface 283 to form an annular receiving groove 281a with different diameters, which helps to guide or position the fourth seal 29.

[0418] The manner in which the second open end 291 is engaged in the receiving groove 281a is not limited.

[0419] For example, the second opening end 291 is designed with a specific shape, such as a flange or edge, which can be directly inserted into the receiving groove 281a and maintain the engagement with the receiving groove 281a by means of friction or shape matching.

[0420] For example, the second open end 291 is connected to the receiving groove 281a by an interference fit.

[0421] In one embodiment, the fourth seal 29 is an elastomer. When the dust cover 28 is installed on the atomizing housing 22, the fourth seal 29 abuts against the nozzle 23 to seal the mist outlet 23a through elastic deformation. This allows the fourth seal 29 to fit more tightly against the mist outlet 23a, forming a good seal.

[0422] Specifically, the material of the fourth seal 29 is not limited, as long as it can produce elastic deformation.

[0423] For example, the fourth seal 29 can be made of silicone, aero-rubber, or fluorosilicone. This allows the fourth seal 29 to provide a better seal to the mist outlet 23a. Furthermore, it gives the fourth seal 29 better corrosion resistance, ensuring it won't be corroded or damaged when in contact with the atomizing liquid in the storage chamber 22a while sealing the mist outlet 23a.

[0424] In one embodiment, the end face of the fourth seal 29 near the mist outlet 23a is either a flat surface or a curved surface. This ensures that the contact area between the fourth seal 29 and the mist outlet 23a is maximized, thereby improving the sealing effect.

[0425] In one embodiment, the hardness of the fourth seal 29 is greater than or equal to Shore A40 and less than or equal to Shore A80. For example, the hardness of the fourth seal 29 may be Shore A40, Shore A60, or Shore A80. Therefore, by using a hardness within the aforementioned range, the fourth seal 29 can possess good elasticity and structural strength, enabling it to adapt to the irregular surface and minute dimensional changes of the mist outlet 23a, thereby improving the sealing effect.

[0426] In one embodiment, referring to Figures 28 and 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 engaging of the connecting buckle 284 with the second connecting slot 22f.

[0427] 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 also have a connecting buckle 284, and the dust cover 28 may have a second connecting slot 22f.

[0428] Understandably, the shape and size of the connecting buckle 284 match the second connecting slot 22f to achieve a snap-fit ​​engagement.

[0429] The snap-fit ​​between the connecting clip 284 and the second connecting slot 22f is detachable, allowing users to easily install and remove the dust cover 28.

[0430] The precise cooperation between the second connecting slot 22f and the connecting buckle 284 enables the fourth sealing element 29 to accurately block the mist outlet 23a of the nozzle 23, thereby improving the sealing effect.

[0431] In one embodiment, referring to FIG. 30, at least a portion of the area of ​​the atomizing housing 22 opposite to the nozzle 23 is recessed to form a second connecting groove 22f. At the mounting inlet 12b, at least a portion of the inner wall of the dust cover 28 extends into the mounting inlet 12b to form a connecting snap 284. Thus, the design of the second connecting groove 22f and the connecting snap 284 ensures the stability of the connection, maintaining a firm connection between the atomizing housing 22 and the dust cover 28 even under vibration or impact.

[0432] Understandably, at least a portion of the inner wall of the dust cover 28 extends into the installation inlet 12b to form a connecting snap 284, which may be a protrusion or a strip.

[0433] There can be multiple protrusions, which are arranged at intervals along the inner circumference of the dust cover 28.

[0434] The raised strip extends circumferentially along the inner wall of the dust cover 28, and the length of the raised strip is less than or equal to the circumferential length of the inner wall of the dust cover 28.

[0435] The end of the atomizing housing 22 opposite to the nozzle 23 may have a portion of the corresponding protrusion or ridge recessed to form a second connecting groove 22f, the length of which 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 groove 22f.

[0436] For example, the atomizing housing 22 has a plurality of second connecting slots 22f, each second connecting slot 22f being spaced apart circumferentially along the atomizing housing 22. The dust cover 28 includes a plurality of spaced connecting buckles 284, each connecting buckle 284 engaging with a corresponding second connecting slot 22f. Thus, the engagement of multiple slots and buckles provides multiple fixing points, increasing the connection stability between the dust cover 28 and the atomizing housing 22, and reducing the risk of the dust cover 28 detaching due to vibration or accidental impact.

[0437] In one embodiment, referring to Figures 24 and 25, the main unit housing 16 has a receiving cavity 16a, and a portion of the main unit housing 16 is open to form a mounting port 16c, which communicates with the receiving cavity 16a.

[0438] 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 receiving cavity 16a, so as to communicate with the outside through the gap of the main housing 16. The area of ​​the air compressor 11 with the air outlet 11a is located in the mounting port 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 cavity 22a respectively.

[0439] Therefore, the first air inlet 11b can be built into the receiving cavity 16a to avoid the first air inlet 11b being directly exposed to the outside of the main housing 16. This reduces the risk of external liquid directly entering the air compressor 11 through the first air inlet 11b, thereby preventing contamination or damage to the inside of the air compressor 11. At the same time, the first air inlet 11b built into the receiving cavity 16a can communicate with the outside through the gap in the main housing 16, so external gas can enter the receiving cavity 16a through the gap in the main housing 16 and then 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 without affecting the normal air intake of the air compressor 11.

[0440] Specifically, the first air inlet 11b of the air compressor 11 is the air inlet for external airflow to enter the air compressor 11.

[0441] The air outlet 11a of the air compressor 11 is an air outlet for high-speed airflow output.

[0442] The area of ​​the air compressor 11 with the first air inlet 11b is located in the receiving cavity 16a. That is to say, the first air inlet 11b of the air compressor 11 is not external to the main housing 16, but is built into the receiving cavity 16a. By building the first air inlet 11b into the receiving cavity 16a, instead of extending to the outer surface of the main housing 16, or directly to the outside of the main housing 16, the risk of external liquids (such as the atomizing liquid in the electronic atomizing device) entering the air compressor 11 through the first air inlet 11b can be greatly reduced.

[0443] Understandably, the first air inlet 11b of the air compressor 11 still needs to be connected to the outside so that the outside airflow can enter the air compressor 11 through the first air inlet 11b.

[0444] The first air inlet 11b of the air compressor 11 is connected to the outside through the gap in the main housing 16.

[0445] It should be noted that the receiving cavity 16a of the main unit housing 16 is not a completely sealed cavity. The main unit housing 16 itself has small gaps. For example, the main unit housing 16 includes multiple walls, which enclose the receiving cavity 16a. At the joints of the walls, a portion of the adjacent walls is spaced apart to form a gap for external airflow to flow into the receiving cavity 16a.

[0446] The number of gaps on the main unit casing 16 can be set according to the actual situation.

[0447] For example, the main housing 16 has multiple gaps, the sum of the areas of each gap being greater than or equal to 1.5 mm². This ensures that outside air enters the receiving cavity 16a through the gaps, and then enters the air compressor 11 through the first air inlet 11b.

[0448] The mounting port 16c of the main unit housing 16 is a connecting port of the air supply port 11a extending into the receiving cavity 16a. Thus, by forming the mounting port 16c, the air outlet 11a of the air compressor 11 can be easily placed outside the receiving cavity 16a, thereby facilitating the high-speed airflow provided by the air compressor 11 to flow out of the main unit housing 16 through the air outlet 11a, and thus facilitating the nozzle 23 to receive it.

[0449] It should also be noted that since the air outlet 11a is for airflow to exit the air compressor 11, while the first air inlet 11b is for airflow to enter 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, placing the first air inlet 11b internally, compared to placing the air outlet 11a internally, can better reduce the risk of liquid entering the air compressor 11.

[0450] The specific dimensions of the first air inlet 11b and the air outlet 11a can be set according to the actual situation.

[0451] 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. The inner diameter of the first air inlet 11b can be 0.7 mm, 1 mm, or 1.5 mm. Using dimensions within the above range for the first air inlet 11b allows the air compressor 11 to have a better air intake effect.

[0452] For 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. The inner diameter of the air outlet 11a can be 0.7 mm, 1 mm, or 1.5 mm. Using the dimensions within the above range for the air outlet 11a allows the air compressor 11 to have a better air output effect.

[0453] Furthermore, the specific shapes of the first air inlet 11b and the air outlet 11a can also be set according to the actual situation.

[0454] For example, the first air inlet 11b is a circular hole, a square hole, or a rectangular hole.

[0455] For example, the air outlet 11a is a circular hole, a square hole, or a rectangular hole.

[0456] In one embodiment, referring to FIG25, the main unit housing 16 includes a connecting end wall 162 having the mounting port 16c, the opening of the first air inlet 11b facing the connecting end wall 162, the first air inlet 11b being offset from the mounting port 16c and spaced apart from the connecting end wall 162.

[0457] Specifically, a portion of the connecting end wall 162 at the end of the main housing 16 is open to form a mounting port 16c. The air outlet 11a extends to the mounting port 16c, thereby facilitating the air compressor 11 to supply air to the nozzle 23 from the mounting port 16c.

[0458] The first air inlet 11b is built into the receiving cavity 16a, and the opening of the first air inlet 11b does not face directly towards the outside of the main housing 16, but rather towards the connecting end wall 162. Furthermore, the first air inlet 11b and the mounting port 16c are offset, meaning they are mutually staggered. Therefore, the connecting end wall 162 can provide some shielding for the first air inlet 11b, reducing the risk of external liquid directly entering the air compressor 11 through the first air inlet 11b. Simultaneously, because the first air inlet 11b and the connecting end wall 162 are spaced apart, the connecting end wall 162 can be prevented from completely blocking the first air inlet 11b, thus preventing problems with air intake obstruction at the first air inlet 11b.

[0459] It should be noted that the specific location where the gap in the main unit casing 16 is formed is not limited.

[0460] For example, the gap in the main housing 16 is designed to avoid the connection end wall 162. Therefore, the gap in the main housing 16 can be positioned as close as possible to the periphery of the main housing 16, or at one end of the main housing 16 opposite to the connection end wall 162. This further reduces the risk of external liquid entering the air compressor 11 through the first air inlet 11b.

[0461] In one embodiment, referring to FIG26, the air compressor 11 has an air compressor end face 111 at the end near 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.

[0462] Specifically, the first air inlet 11b and the air outlet 11a are both located on the end face of the air compressor 11 near the mounting port 16c. This allows the airflow entering the air compressor 11 from the first air inlet 11b to flow out from the air outlet 11a more conveniently.

[0463] The air intake area is the area on the air compressor end face 111 used to form the first air intake port 11b, and the air outlet area is the area on the air compressor end face 111 used to form the air outlet port 11a.

[0464] By making the air outlet area protrude, it is easier to extend the air outlet 11a into the mounting port 16c, thereby facilitating the air outlet 11a to discharge air.

[0465] Thus, the air intake area and the air outlet area form a certain length difference in the longitudinal direction, which also makes it easier for the first air intake 11b to be built into the receiving cavity 16a.

[0466] In one embodiment, referring to Figures 26 and 27, the intake area is recessed to form a recessed space 111a, and the wall of the first intake port 11b extends into the recessed space 111a to be spaced apart from the connecting end wall 162.

[0467] Specifically, the 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 from fitting with the first air inlet 11b and blocking the first air inlet 11b, thus ensuring a better air intake effect.

[0468] In one embodiment, at least a portion of the outer peripheral surface of the air compressor 11 is spaced apart from the main housing 16 to form a spacer space, and the recessed space 111a extends to one side of the air compressor 11 in the circumferential direction to communicate with the spacer space.

[0469] Specifically, the outer peripheral surface of the air compressor 11 may be partially spaced from the main housing 16, forming a gap space at the interval. Of course, the entire outer peripheral surface of the air compressor 11 may be spaced from the main housing 16, forming a gap space at the interval.

[0470] Furthermore, by opening one side of the recessed space 111a to communicate with the partition space, it is possible for external airflow to enter the receiving cavity 16a through the gap in the main unit housing 16, and then enter the air compressor 11 through the partition space and the recessed space 111a, thereby providing the air intake effect of the air compressor 11.

[0471] Another embodiment of this application provides a liquid injection device, as shown in FIG31. The liquid injection device includes a liquid injection housing 30 and a liquid injection assembly 40.

[0472] The liquid filling housing 30 has a liquid storage space 30a and a liquid supply port 30b, and the liquid storage space 30a is connected to the liquid supply port 30b.

[0473] Please refer to Figure 32. The injection assembly 40 includes an injection head 41 and a second one-way valve 42. The injection head 41 has a second injection port 41a and is covered by the end of the injection housing 30 with a supply port 30b, so that an outlet path is formed between the supply port 30b and the second injection port 41a. The second one-way valve 42 is disposed between the injection head 41 and the supply port 30b to switch between opening and closing the outlet path.

[0474] Therefore, by setting a second one-way valve 42, during the process of the liquid injection device injecting liquid into the electronic atomizing device, the second one-way valve 42 can open the liquid outlet path, so that the atomized liquid in the liquid storage space 30a can flow out along the liquid outlet path to replenish the electronic atomizing device. At the same time, after the liquid injection is completed, the second one-way valve 42 can close the liquid outlet path to prevent the atomized liquid in the liquid storage space 30a from flowing out from the liquid supply port 30b and the second liquid injection port 41a. Therefore, it can reduce the risk of leakage and prevent the atomized liquid in the liquid storage space 30a from being exposed, thus preventing solution waste and pollution.

[0475] Specifically, the liquid injection device is used to replenish the atomizing liquid into the electronic atomizing device described in any embodiment of this application.

[0476] The liquid storage space 30a is the liquid storage space 30a in the liquid injection device used to store the atomizing liquid.

[0477] The liquid supply port 30b is the outlet for the atomized liquid flowing out of the liquid storage space 30a.

[0478] The second injection port 41a is used to allow the atomized liquid from the outlet to flow out of the injection device to replenish the electronic atomizing device.

[0479] The injection head 41 is positioned over the supply port 30b, allowing the atomized liquid in the storage space 30a to flow out of the injection device through the supply port 30b and the second injection port 41a. This creates an outlet path for the atomized liquid to flow from the supply port 30b to the second injection port 41a.

[0480] The second one-way valve 42 is located between the injection head 41 and the supply port 30b. In fact, the second one-way valve 42 is situated on the liquid outlet path. By opening the second one-way valve 42, communication is established between the supply port 30b and the second injection port 41a, allowing the atomizing liquid to flow from the supply port 30b to the second injection port 41a and out of the injection device. By closing the second one-way valve 42, the injection head 41 and the supply port 30b are separated, thus preventing the atomizing liquid from flowing from the supply port 30b to the second injection port 41a. Therefore, by opening and closing the second one-way valve 42, switching between opening and closing the liquid outlet path can be achieved.

[0481] 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 atomizing liquid to flow unidirectionally from the liquid supply port 30b to the second liquid injection port 41a, but cannot allow the atomizing liquid to flow from the second liquid injection port 41a to the liquid supply port 30b.

[0482] The specific material of the second check valve 42 is not limited; for example, the material of the second check valve 42 can be either silicone or rubber. This allows the second check valve 42 to have good sealing performance and elastic deformation capability.

[0483] For example, the material hardness of the second check valve 42 is greater than or equal to Shore A40 and less than or equal to Shore A80. For instance, Shore A40, Shore A60, and Shore A80. Therefore, by using the aforementioned material hardness, the second check valve 42 can possess better structural strength and thus better wear resistance.

[0484] The liquid injection device of this application can greatly reduce the risk of leakage 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 liquid injection device low in cost.

[0485] In one embodiment, referring to Figures 32, 33 and 34, a second check valve 42 is disposed at the liquid supply port 30b. The second check valve 42 has a valve port 42a that is connected to the liquid supply port 30b and the second liquid injection port 41a respectively. The valve port 42a is located on the liquid outlet path. Under the action of external force, the second check valve 42 switches between opening and closing the liquid outlet path by switching the valve port 42a between open and closed.

[0486] Specifically, the second one-way valve 42 opens its valve port 42a, 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 its valve port 42a, separating the liquid supply port 30b from the second liquid injection port 41a, thereby cutting off the liquid outlet path.

[0487] Therefore, by opening and closing the valve port 42a of the second one-way valve 42, the leak-proof effect of the injection device can be improved, without affecting the injection process of the injection device.

[0488] In one embodiment, referring to Figure 34, the 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 one end of the second valve body 421 near the second liquid injection port 41a. The valve nozzle 422 includes a first fitting portion 423 and a second fitting portion 424 disposed on the second valve body 421. At least a portion of the first fitting portion 423 and the second fitting portion 424 are disconnected and fitted together at the end of the valve nozzle 422 near the second liquid injection port 41a to form a closed valve port 42a. When the liquid injection shell 30 is squeezed by an external force, under the action of the air pressure difference inside and outside the liquid storage space 30a, the disconnected parts of the first fitting portion 423 and the second fitting portion 424 separate from each other, so that the valve port 42a opens. Thus, while enabling the second one-way valve 42 to have the function of opening and closing the liquid outlet path, the structure of the second one-way valve 42 can be greatly simplified.

[0489] Specifically, the valve nozzle 422 has a valve port 42a. At the valve port 42a, the first fitting portion 423 and the second fitting portion 424 are not continuously connected, but are disconnected from each other. At the same time, when the user does not squeeze the liquid injection housing 30, the first fitting portion 423 and the second fitting portion 424 are in contact with each other, thereby closing the valve port 42a and stopping the liquid discharge path.

[0490] When the user applies pressure to the liquid injection housing 30, the liquid storage space 30a of the liquid injection housing 30 is compressed. The pressure inside the liquid storage space 30a is greater than the pressure outside the liquid storage space 30a, causing the first fitting part 423 and the second fitting part 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 under the action of the air pressure difference, and then flow out of the liquid injection device.

[0491] It should be noted that the specific structural form of the second check valve 42 can be set according to the actual situation.

[0492] For example, referring to Figure 34, the cross-sectional dimension of the second valve body 421 gradually decreases from the end opposite to the second injection port 41a to the end closer to the second injection port 41a. That is, the external dimensions of the second valve body 421 gradually decrease towards the direction closer to the second injection port 41a. As a result, the space within the second valve body 421 for the flow of atomizing liquid also gradually decreases, thereby guiding the atomizing liquid to flow towards the direction closer to the second injection port 41a, so that the atomizing liquid can flow out from the second injection port 41a.

[0493] For example, the cross-sectional dimension of the valve nozzle 422 gradually decreases from the end away from the second injection port 41a to the end closer to the second injection port 41a. Therefore, the overall size of the valve nozzle 422 can gradually decrease towards the second injection port 41a, further guiding the atomizing liquid to flow towards the second injection port 41a.

[0494] In one embodiment, referring to FIG34, both the first fitting portion 423 and the second fitting portion 424 are inclined surfaces, and from the end away from the second injection port 41a to the end near the second injection port 41a, the first fitting portion 423 and the second fitting portion 424 are inclined in a direction that approaches each other.

[0495] Specifically, from the end away from the second injection port 41a to the end near the second injection port 41a, by setting the first contact portion 423 and the second contact portion 424 as inclined surfaces, the distance between the first contact portion 423 and the second contact portion 424 can be gradually reduced until they are in contact. Thus, on the one hand, after the external force is removed, the valve ports 42a can be brought into contact with each other, thereby achieving the purpose of closing the valve ports 42a. On the other hand, since the first contact portion 423 and the second contact portion 424 are inclined surfaces, the atomized liquid can be guided to flow towards the direction near the second injection port 41a.

[0496] In one embodiment, referring to Figure 34, the second valve body 421 has a vent 421a, which communicates with both the liquid storage space 30a and the outside environment, thus forming a ventilation path through the vent 421a between the outside environment and the liquid storage space 30a. This allows external airflow to easily enter the liquid storage space 30a through the vent 421a, replenishing the liquid storage space 30a with gas, thereby facilitating subsequent liquid injection by the injection device.

[0497] Specifically, the ventilation path is the airflow path that allows external airflow to flow into the liquid storage space 30a.

[0498] When the user applies pressure 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, since the valve port 42a is located at the end of the valve nozzle 422 near the second liquid injection port 41a, and the vent 421a is located on the second valve body 421, the atomized liquid will pass through the second one-way valve 42 from the position where it is easiest to flow out, that is, more atomized liquid will pass through the valve port 42a.

[0499] Therefore, it is possible to allow most of the atomizing liquid to flow through the valve port 42a to the second injection port 41a, with only a small portion of the atomizing liquid flowing through the vent 421a to the second injection port 41a. Alternatively, it is possible to allow all the atomizing liquid to flow through the valve port 42a to the second injection port 41a, with no atomizing liquid flowing through the vent 421a to the second injection port 41a.

[0500] When the user removes the pressure applied to the injection housing 30, the injection housing 30 elastically returns to its initial state, requiring external gas to be replenished into the storage space 30a. However, since the pressure applied to the injection housing 30 is removed, the separation points of the first and second fitting portions 423 and 424 reclose, preventing external gas from replenishing the storage space 30a through the valve port 42a. Therefore, by providing the vent 421a, external gas can flow along the venting path and enter the storage space 30a through the vent 421a, facilitating the return of the injection housing 30 to its initial state. This allows the user to easily re-squeeze the injection housing 30, enabling the injection device to re-inject liquid.

[0501] In one embodiment, referring to Figures 31 and 32, the sidewall of the liquid supply port 30b protrudes outward toward the liquid storage space 30a to form a connecting boss 31. The injection head 41 has a receiving space 41b communicating with the second injection port 41a. The second one-way valve 42 is disposed in the receiving space 41b. The injection head 41 covers the connecting boss 31, and the connecting boss 31 extends into the receiving space 41b so that the second one-way valve 42 is squeezed and fixed at the liquid supply port 30b.

[0502] Specifically, by forming the connecting boss 31, the injection head 41 and the second check valve 42 can be easily connected to the injection housing 30. By covering the injection head 41 on the connecting boss 31, the second check valve 42 can be pressed against the supply port 30b, thereby improving the installation stability of the second check valve 42 and reducing the risk of leakage of atomized liquid from the supply port 30b.

[0503] It should be noted that the injection head 41 and the connecting boss 31 can be connected in a non-detachable manner. Of course, a detachable connection can also be used, which allows the injection head 41 and the connecting boss 31 to be easily separated for maintenance and replacement of the second check valve 42.

[0504] For example, an internal thread is formed on the inner wall of the receiving space 41b, and an external thread is formed on the outer wall of the connecting boss 31, thereby enabling a threaded connection between the injection head 41 and the connecting boss 31.

[0505] Of course, the injection head 41 and the connecting boss 31 can also be detachably snapped, plugged in or otherwise detachably connected.

[0506] In one embodiment, please refer to Figures 33 and 34. The connecting boss 31 includes a connecting end face 31a near the second injection port 41a. The second one-way valve 42 has a flange 425 formed at one end near the connecting boss 31. The flange 425 fits against the connecting end face 31a.

[0507] Specifically, the end face of the second check valve 42 near the connecting boss 31 extends radially outward to form a flange 425 that folds over the outer peripheral surface of the second check valve 42. By forming the flange 425, the second check valve 42 can be easily fitted to the connecting end face 31a, making the second check valve 42 more stable under the pressure of the connecting boss 31 and the injection head 41.

[0508] In one embodiment, referring 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, by sealing the second injection port 41a with the sealing cap 412, the risk of leakage of the injection device can be further reduced, and the sealing performance of the injection device can be improved.

[0509] In one embodiment, the second injection port 41a of the injection device is connected to the inlet port. The user can squeeze the injection shell 30 to allow the atomized liquid in the injection device to pass through the second injection port 41a and the inlet port, thereby replenishing the liquid storage space 30a of the electronic atomizing device, thus realizing the replenishment of liquid into the electronic atomizing device.

[0510] One embodiment of this application provides an electronic atomizing device. Please refer to Figures 1 and 35. The electronic atomizing device includes a main unit module 10 and an atomizer module 20.

[0511] The main unit module 10 includes a power supply component 13 and an air compressor 11, which are electrically connected.

[0512] The atomizer module 20 includes an atomizing housing 22, a comb assembly 224, and a nozzle 23. The nozzle 23 has a mist outlet 23a and is disposed on the atomizing housing 22. The atomizing housing 22 has an air passage 22b and a liquid storage chamber 22a. The air compressor 11 is connected to one end of the air passage 22b. The nozzle 23 is connected to the other end of the air passage 22b and the liquid storage chamber 22a respectively, so that the airflow from the air compressor 11 atomizes the atomizing liquid from the liquid storage chamber 22a to generate an aerosol.

[0513] The comb assembly 224 is disposed at one end of the atomizing housing 22 near the mist outlet 23a. The comb assembly 224 includes a comb member 2241 located on the periphery of the mist outlet 23a. Along the circumference of the nozzle 23, the comb member 2241 has a first comb surface 224a and a second comb surface 224b on opposite sides. At the end of the comb member 2241 away from the mist outlet 23a, the first comb surface 224a and the second comb surface 224b are in contact, and the distance between the first comb surface 224a and the second comb surface 224b gradually increases in the direction closer to the mist outlet 23a.

[0514] Specifically, for ease of description, this application uses an electronic atomizing device as an example of a scalp atomizing drug delivery device.

[0515] The comb assembly 224 is located at the end of the atomizing housing 22 near the mist outlet 23a. Thus, during use, the user can use the comb assembly 224 at the end to part the hair so that the atomized liquid flowing from the mist outlet 23a can reach the scalp, thereby minimizing the amount of hair that gets on the hair.

[0516] The comb teeth 2241 are located around the mist outlet 23a to avoid the mist outlet 23a's misting direction, thus avoiding affecting the misting effect of the mist outlet 23a while separating the hair.

[0517] The outer surface of the comb 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 meet at the end of the comb 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 closer 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. As a result, the distance between the first comb tooth surface 224a and the second comb tooth surface 224b can gradually increase, so as to facilitate the separation of hair.

[0518] 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 planes, curved surfaces, etc.

[0519] For example, the first comb tooth surface 224a and the second comb tooth surface 224b are mutually inclined planes, and the included 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°.

[0520] Specifically, the first comb surface 224a and the second comb surface 224b adopt a planar structure, which facilitates guiding the hair to separate. Simultaneously, the included angle between the two is set between 30° and 120° to achieve a better parting effect. For example, an included angle greater than or equal to 45° and less than or equal to 90°. Setting the included angle between 45° and 90° can further improve the parting effect.

[0521] The first comb tooth surface 224a and the second comb tooth surface 224b are connected to each other on the side away from the mist outlet 23a, and the specific connection method is not limited.

[0522] For example, referring to Figure 36, the junction of the first comb tooth surface 224a and the second comb tooth surface 224b on the side facing away from the mist outlet 23a is smoothly transitioned. Specifically, a smooth transition means that the junction of the first comb tooth surface 224a and the second comb tooth surface 224b is smoothly connected, without obvious protrusions, folds, or abrupt changes. For example, the junction of the first comb tooth surface 224a and the second comb tooth surface 224b is smoothly connected by an arc surface. It should be noted that adopting a smooth transition method can avoid abrupt changes at the junction, thus preventing the end of the comb tooth 2241 facing away from the mist outlet 23a from being too sharp, reducing the problem of the comb tooth 2241 scratching the scalp or damaging the hair due to sharpness.

[0523] The electronic atomizing device of this application embodiment includes a main unit module 10 and an atomizer module 20. The comb assembly 224 of the atomizer module 20 is disposed at one end of the atomizing housing 22 near the mist outlet 23a. The comb assembly 224 includes comb teeth 2241 located around the mist outlet 23a. Thus, when applying medicine to the scalp through the electronic atomizing device, the comb teeth 2241 located around the mist outlet 23a can separate the hair, effectively separating the hair so that the medicine can be better delivered to the scalp. On the other hand, along the circumference of the nozzle 23, the comb teeth 2241 has a first comb tooth surface 224a and a second comb tooth surface 224b on opposite sides. At the end of the comb teeth 2241 away from the mist outlet 23a, the first comb tooth surface 224a and the second comb tooth surface 224b are in contact, and the distance between the first comb tooth surface 224a and the second comb tooth surface 224b gradually increases in the direction closer to the mist outlet 23a. The design of gradually increasing distance towards the mist outlet 23a allows the comb teeth 2241 to better separate the hair through the first comb tooth surface 224a and the second comb tooth surface 224b, reducing the risk of hair blocking the mist outlet 23a and thus improving the distribution effect. This also facilitates the misting and application of medicine by the electronic atomizing device.

[0524] In one embodiment, referring to Figures 36 and 39, the comb 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 the side opposite to the second comb tooth portion 2243, and the second comb tooth portion 2243 has a second comb tooth surface 224b on the side opposite to the first comb tooth portion 2242. The ends of the first comb tooth portion 2242 and the second comb tooth portion 2243 opposite to the mist outlet 23a are connected to each other. Along the direction near the mist outlet 23a, the first comb tooth portion 2242 and the second comb tooth portion 2243 are inclined in a direction away from each other, and both extend to the end of the comb 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 dispensing effect and facilitates application of medication to the scalp.

[0525] Specifically, the first comb tooth portion 2242 has a first comb tooth surface 224a, and the second comb tooth portion 2243 has a second comb tooth surface 224b. The first comb tooth portion 2242 and the second comb tooth portion 2243 are inclined relative to each other, such that their ends away from the mist outlet 23a are connected together, while their ends near the mist outlet 23a are spaced apart. As a result, the comb tooth component 2241 is roughly "arrow" shaped, and its cross-sectional shape is roughly "V" shaped, which can be used to separate hair to facilitate the application of medicine to the scalp.

[0526] 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 component 2241 near the mist outlet 23a. This ensures that the first comb tooth surface 224a and the second comb tooth surface 224b are long enough to ensure the dispensing effect of the comb tooth component 2241.

[0527] A space is formed between the ends of the first comb tooth portion 2242 and the second comb tooth portion 2243 near the mist outlet 23a. In fact, in other embodiments, the ends of the first comb tooth portion 2242 and the second comb tooth portion 2243 near the mist outlet 23a can also be connected together instead of using a spaced-out form.

[0528] In one embodiment, referring to Figure 41, both the first comb tooth surface 224a and the second comb tooth surface 224b extend to the end of the comb member 2241 near the mist outlet 23a. The sides of the first comb tooth surface 224a and the second comb tooth surface 224b opposite to the mist outlet 23a are smoothly connected by an arc surface, and the sides of the first comb tooth surface 224a and the second comb tooth surface 224b near the mist outlet 23a are also smoothly connected by an arc surface. This facilitates separating the hair for easier application of medication to the scalp.

[0529] Specifically, the first comb tooth surface 224a and the second comb tooth surface 224b both extend from the end of the comb tooth member 2241 away from the mist outlet 23a to the end of the comb tooth member 2241 near the mist outlet 23a. This ensures that the first comb tooth surface 224a and the second comb tooth surface 224b are long enough to ensure the dispensing effect of the comb tooth member 2241.

[0530] The first comb tooth surface 224a and the second comb tooth surface 224b both adopt curved transitions on the side away from the mist outlet 23a and the side closer to the mist outlet 23a, respectively. This makes the connection between the two sides of the first comb tooth surface 224a and the second comb tooth surface 224b smoother, avoiding damage to the scalp and hair caused by excessively sharp joints. For example, the comb tooth component 2241 is roughly triangular pyramidal in shape, and its cross-sectional shape is roughly arc-triangular.

[0531] In one embodiment, referring to Figure 40, the comb member 2241 further has 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 as and connected to the first comb tooth surface 224a, and the fourth comb tooth surface 224d is located on the same side as and connected to the second comb tooth surface 224b. At the end of the comb member 2241 near the mist outlet 23a, the third comb tooth surface 224c and the fourth comb tooth surface 224d are connected, and the distance between them gradually increases in the direction away from the mist outlet 23a. This facilitates separating the hair for easier application of medication to the scalp.

[0532] Specifically, the first comb tooth surface 224a and the second comb tooth surface 224b do not extend to the end of the comb member 2241 near the mist outlet 23a. The comb member 2241 has a third comb tooth surface 224c and a first comb tooth surface 224a on one side of 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 near the mist outlet 23a. On the other side of the circumference of the nozzle 23, the comb member 2241 has a fourth comb tooth surface 224d and a second comb tooth surface 224b, and the fourth comb tooth surface 224d is located on the side of the second comb tooth surface 224b near the mist outlet 23a.

[0533] In other words, the third comb tooth surface 224c and the fourth comb tooth surface 224d correspond to each other, and the first comb tooth surface 224a and the second comb tooth surface 224b correspond to each other. From the side away from the mist outlet 23a to the side closer 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. However, the third comb tooth surface 224c and the fourth comb tooth surface are inclined in a direction closer to each other.

[0534] For example, the comb tooth 2241 has a "rhombus" structure, and its cross-sectional shape is rhombus.

[0535] The number of comb teeth 2241 is unlimited; there can be one or more.

[0536] In one embodiment, referring to Figure 36, the comb assembly 224 includes a plurality of comb teeth 2241 spaced circumferentially along the nozzle 23. One comb tooth 2241 is disposed on each opposite side of the nozzle 23 along a fourth direction, and another comb tooth 2241 is disposed on each opposite side of the nozzle 23 along a fifth direction, with the fourth and fifth directions being perpendicular. This allows the electronic atomizing device to comb through the hair in at least four directions, facilitating the application of medication to the scalp.

[0537] Specifically, the comb assembly 224 includes multiple comb teeth 2241, each comb tooth 2241 being disposed on the periphery of the nozzle 23 and spaced apart along the circumference of the nozzle.

[0538] The comb assembly 224 may consist of only two comb teeth 2241 located on opposite sides of the nozzle 23 along the fourth direction, and two comb teeth 2241 located on opposite sides of the nozzle 23 along the fifth direction, for a total of four comb teeth 2241. Since the fourth and fifth directions are perpendicular, the comb teeth 2241 positioned at different locations can comb the hair accordingly as the electronic atomizing device is moved in different directions.

[0539] Of course, in other embodiments, the comb assembly 224 may also include comb teeth 2241 disposed in other locations.

[0540] For example, referring to Figure 39, comb teeth 2241 are also provided at intervals on the fourth and fifth directions of the nozzle 23.

[0541] Specifically, in addition to the two comb teeth 2241 on opposite sides of the nozzle 23 along the fourth direction and the two comb teeth 2241 on opposite sides along the fifth direction, a comb tooth 2241 is also provided between the comb tooth 2241 provided along the fourth direction and the adjacent comb tooth 2241 provided along the fifth direction. The number of such comb teeth is not limited, such as one or more.

[0542] This allows the electronic atomizing device to include at least eight comb teeth 2241 facing different directions, ensuring effective hair separation.

[0543] In one embodiment, referring to Figures 36 and 39, the comb assembly 224 includes a plurality of comb teeth 2241 spaced circumferentially along the nozzle 23. The comb assembly 224 also includes a plurality of comb posts 2244, each comb post 2244 spaced circumferentially along the nozzle 23 and located on the outer periphery of each comb tooth 2241. Along the radial direction of the nozzle 23, the comb posts 2244 are staggered from adjacent comb teeth 2241. Therefore, by providing the comb posts 2244, it is easier to straighten the hair, thereby facilitating the comb teeth 2241 to comb through the hair and improve the drug delivery effect.

[0544] Specifically, the comb post 2244 has a columnar structure, which can be a cylinder, prism, frustum, etc.

[0545] The comb assembly 224 includes a plurality of comb teeth 2241 and a plurality of comb teeth 2244. Each comb tooth 2241 and each comb teeth 2244 are arranged circumferentially around the nozzle 23, with each comb tooth 2241 located on the inner ring close to the nozzle 23 and each comb teeth 2244 located on the outer ring away from the nozzle 23.

[0546] It should be noted that the comb post 2244 and the adjacent comb piece 2241 are staggered to avoid the comb post 2244 and the comb piece 2241 being in the same radial direction. Therefore, the comb post 2244 can avoid blocking the comb piece 2241 and prevent the distribution effect of the comb piece 2241 from being reduced.

[0547] In one embodiment, referring to Figure 35, the atomizing housing 22 includes an atomizing bullet 221 and a comb tooth mounting base 226. The atomizing bullet 221 has a liquid storage chamber 22a, and a nozzle 23 is located inside the comb tooth mounting base 226. One end of the nozzle 23 with 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 bullet 221 and the comb tooth assembly 224, respectively. This facilitates the installation of the comb tooth assembly 224 on the atomizing bullet 221 and also facilitates the assembly and disassembly of the atomizing bullet 221.

[0548] Specifically, the comb mounting base 226 is used to connect the atomizing bullet 221 and the comb assembly 224. In fact, a cavity is formed within the comb mounting base 226 to accommodate the nozzle 23. One end of the nozzle 23, having a mist outlet 23a, extends out of the cavity to facilitate mist discharge to the outside.

[0549] The atomizing bullet 221 is detachably connected to the comb tooth mounting base 226, which allows the atomizing bullet 221 to be easily removed and replaced.

[0550] In one embodiment, referring to Figures 35 and 36, the comb assembly 224 includes a mounting plate 2245 with a mounting hole 224e. The mounting plate 2245 is detachably connected to the comb mounting base 226. One end of the nozzle 23 with a mist outlet 23a passes through the mounting hole 224e, and the comb teeth 2241 are disposed on the end face of the mounting plate 2245 near the mist outlet 23a. Therefore, by providing the mounting plate 2245, the comb teeth 2241 can be easily installed on the periphery of the mist outlet 23a, and the comb teeth 2241 can be securely installed on the comb mounting base 226, thereby improving structural stability.

[0551] Specifically, the mounting hole 224e is used for the end of the nozzle 23 with the mist outlet 23a to pass through, and the comb tooth 2241 is disposed on the side of the mounting plate 2245 away from the comb tooth mounting seat 226 so that the comb tooth 2241 can separate the hair so that the atomized liquid flowing from the mist outlet 23a can be applied to the scalp.

[0552] It should be noted that the mounting plate 2245 and the comb tooth 2241 can be integrally formed or separately formed.

[0553] In one embodiment, referring to Figures 36 to 38, a portion of the outer edge of the mounting disc 2245 protrudes towards the side near the comb tooth mounting base 226 to form a plurality of first positioning members 2246 spaced circumferentially along the nozzle 23. A first latch 224f is formed at the interval between two adjacent first positioning members 2246. A portion of the end face of the comb tooth mounting base 226 near the mounting disc 2245 protrudes to form a plurality of latching members 2261 spaced circumferentially along the nozzle 23. The latching members 2261 are correspondingly engaged in the first latches 224f to engage the mounting disc 2245 with the comb tooth mounting base 226. This improves the connection stability between the mounting disc 2245 and the comb tooth mounting base 226.

[0554] Specifically, the first positioning element 2246 is a protruding structure on the end face of the mounting plate 2245 near the comb mounting seat 226. The first positioning element 2246 is located on the outer edge of the mounting plate 2245, and each first positioning element 2246 is spaced apart along the circumference of the mounting plate 2245 (which is also the circumference of the nozzle 23).

[0555] Because the adjacent first positioning members 2246 are spaced apart, a first bayonet 224f is formed at the interval. The snap-fit ​​member 2261 is a protruding structure that protrudes towards the side near the mounting plate 2245, and its position, number and shape correspond one-to-one with the first bayonet 224f.

[0556] When the mounting plate 2245 is detachably mounted on the comb mounting base 226, the snap-fit ​​piece 2261 snaps into the first snap-fit ​​slot 224f, thereby enabling a stable connection between the mounting plate 2245 and the comb mounting base 226.

[0557] In one embodiment, referring to Figures 36 to 38, a portion of the end face of the mounting disc 2245 near the comb mounting base 226 protrudes to form a plurality of second positioning members 2247 spaced circumferentially along the nozzle 23, and each second positioning member 2247 is located on the inner circumferential side of each first positioning member 2246. A second latch 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 spaced apart in a one-to-one correspondence so that an annular groove 224h is formed at the interval.

[0558] A portion of the end face of the comb mounting base 226 near 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 mounting base 226, the retaining ring 2262 is engaged in the annular groove 224h, and the engaging member 2261 is engaged in the second slot 224g.

[0559] Specifically, the second positioning member 2247 is a protruding structure protruding from the end face of the mounting plate 2245 near the comb mounting seat 226. Each second positioning member 2247 is arranged at intervals along the circumference of the nozzle 23, and the second positioning member 2247 is located on the side of each first positioning member 2246 near the nozzle 23.

[0560] The number of second positioning members 2247 is the same as that of the first positioning members 2246, and they are arranged at intervals corresponding to the first positioning members 2246. On the one hand, each second positioning member 2247 can be radially connected to the first positioning member 2246 at intervals, thereby forming an annular groove 224h. On the other hand, since each adjacent second positioning member 2247 is arranged at intervals, a second bayonet 224g is formed at the intervals.

[0561] The retaining ring 2262 is a protruding structure on the side of the comb tooth mounting base 226 that protrudes towards the mounting plate 2245, and its setting position corresponds to the annular retaining groove 224h.

[0562] When the mounting plate 2245 is detachably mounted on the comb mounting base 226, the snap-fit ​​member 2261, which is locked in the first snap-fit ​​224f, extends into the second snap-fit ​​224g, and the snap ring 2262 is locked in the annular snap groove 224h, thereby enabling a stable connection between the mounting plate 2245 and the comb mounting base 226.

[0563] In one embodiment, referring to Figures 36 to 38, a portion of the end face of the mounting disc 2245 near the comb tooth mounting base 226 protrudes to form a plurality of snap-fit ​​posts 2248 spaced circumferentially along the nozzle 23. A portion of the end face of the comb tooth mounting base 226 near the mounting disc 2245 is recessed to form a plurality of snap-fit ​​holes 226a spaced circumferentially along the nozzle 23. The snap-fit ​​posts 2248 are correspondingly engaged in the snap-fit ​​holes 226a to engage the mounting disc 2245 with the comb tooth mounting base 226. This ensures a stable connection between the mounting disc 2245 and the comb tooth mounting base 226.

[0564] Specifically, the comb mounting base 226 has multiple snap-fit ​​holes 226a on the end face near the mounting plate 2245. The snap-fit ​​holes 226a can be through holes that penetrate the end face of the comb mounting base 226, or recessed holes that do not penetrate the end face. Through the snap-fit ​​engagement of the snap-fit ​​posts 2248 with the snap-fit ​​holes 226a, the connection between the mounting plate 2245 and the comb mounting base 226 can be made more stable.
