[0031] Figures 1 to 7 It is the accompanying drawing of the present utility model.

[0032] This embodiment provides a power supply device 10, see Figures 1 to 4, includes a shell 11, a mounting base 12 arranged in the shell 11, and an airflow sensor 13 arranged on the mounting base 12. The mounting base 12 is provided with an air inlet 121 that passes through the upper and lower end surfaces. The air inlet 121 is provided at one end on the lower end surface of the mounting base 12, and at the other end on the upper end surface of the mounting base 12, that is, the air inlet 121 passes through the upper and lower end surfaces of the mounting base 12. The air inlet 121 is used to pass air entering from the outside. An air inlet is provided at the bottom of the shell 11, and air enters the interior of the shell 11 from the air inlet, and then flows out from the air inlet. A mounting cavity 122 for installing the airflow sensor 13 is provided at the lower end of the mounting base 12. The mounting cavity 122 serves as a cavity facing the inner cavity of the shell 11, which facilitates the coordinated installation of other components. One end of the air inlet 121 located on the lower end surface of the mounting base 12 is located in the mounting cavity 122. One end of the air inlet 121 is located on the lower surface of the mounting base 12, and the mounting cavity 122 is also located on the lower surface of the mounting base 12. Therefore, one end of the air inlet 121 is located within the mounting cavity 122, meaning that air must pass through the mounting cavity 122 to enter the air inlet 121. An airflow sensor 13 is located within the mounting cavity 122, with its sensing end connected to the air inlet 121. When the atomizer is operating, external air passes through the air inlet 121. The disturbance in the airflow triggers the airflow sensor 13, which in turn sends a start signal, instructing the control module to output power to the cigarette cartridge.

[0033] The housing 11 is open at the top and can be understood as a barrel-shaped structure. The mounting base 12 is installed into the inner cavity of the housing 11 through the upper end opening. The inner cavity of the housing 11 is provided with a slot. When the mounting base 12 is installed into the inner cavity of the housing 11, the block provided on the outside of the mounting base 12 is installed into the slot, so that the mounting base 12 is fixed in the inner cavity of the housing 11.

[0034] See also Figures 2 to 6 The mounting cavity 122 is provided with a seal 14, and the airflow sensor 13 is mounted to the mounting cavity 122 via the seal 14. During operation, to ensure the sealing of the sensing end of the airflow sensor 13 and prevent it from being affected by other airflows, the outer periphery of the airflow sensor 13 and the mounting component must remain sealed. Therefore, the airflow sensor 13 is mounted to the mounting cavity 122 via the seal. This not only ensures the sealing between the outer periphery of the airflow sensor 13 and the seal 14, but also facilitates the installation of the airflow sensor 13 to the mounting base 12. The outer surface of the seal 14 is in close contact with the inner wall of the mounting cavity 122, improving the sealing effect and preventing air from passing through the gap between the seal 14 and the inner wall of the mounting cavity 122.

[0035] The seal 14 is provided with a mounting hole 141 for mounting the airflow sensor 13, and the mounting hole 141 is connected to the air inlet 121, so that when air passes through the air inlet 121, the airflow sensor 13 can be triggered. The sensing end of the airflow sensor 13 is located within the mounting hole 141, and the outer side of the airflow sensor 13 is sealed with the mounting hole 141. Therefore, the sensing end of the airflow sensor 13 is not disturbed by external airflow, and the triggering of the sensing end is only caused by air disturbances from the air inlet 121. The mounting cavity 122 is provided on the lower end surface of the mounting base 12. The mounting cavity 122 is designed to be open to the interior of the housing 11. Therefore, the seal 14 blocks the open end of the mounting cavity 122 from the lower end of the mounting base 12, facilitating the installation of the seal 14 into the mounting cavity 122. When the seal 14 is installed from the lower end into the mounting cavity 122, no other tools are required and it can be installed by hand, improving assembly efficiency. The seal 14 forms an integral unit with the airflow sensor 13 and then with the mounting base 12, making it easy to install into the housing 11. The mounting hole 141 is connected to the air inlet 121, so that when the air in the air inlet 121 is disturbed, it can trigger the airflow sensor 13 installed in the mounting hole 141. The installation of the airflow sensor 13 to the seal 14 not only ensures the airtightness between the airflow sensor 13 and the seal 14, but also allows the airflow sensor 13 and the seal 14 to form an integral unit. The seal 14 and the airflow sensor 13 are installed together in the mounting cavity 122, making the installation process easy to streamline and improving installation efficiency.

[0036] In other embodiments, the mounting cavity 122 opens toward one side of the mounting base 12, and the seal 14 is installed into the mounting cavity 122 from one side of the mounting base 12. After the mounting base 12 is installed into the housing 11, the mounting cavity 122 faces the inner wall of the housing 11, and after the seal 14 is installed, one side of the seal 14 abuts against the inner wall of the housing 11, thereby securing the seal 14.

[0037] In other embodiments, the air inlet 121 extends through the upper and lower end surfaces of the mounting base 12, and the airflow sensor 13 is mounted on the sealing member 14. A transverse hole or transverse groove is provided in the mounting base 12, communicating with the sensing end of the airflow sensor 13. One end of the transverse hole or transverse groove communicates with the air inlet 121, and the other end communicates with the sensing end of the airflow sensor 13, so that air passing through the air inlet 121 can trigger the airflow sensor 13. If the transverse hole is provided, it is provided inside the mounting base 12; if the transverse groove is provided, it is provided on the outer surface of the mounting base 12.

[0038] See also Figure 3 、 56. Because seal 14 is sealed within mounting cavity 122, the contact between the two forms a sealed connection. Furthermore, air inlet 121 must penetrate the upper and lower end surfaces of mounting base 12. Therefore, seal 14 is provided with a through hole 142 that communicates with air inlet 121. Through hole 142 is positioned on seal 14 near air inlet 121. One end of through hole 142 is located at the lower end of seal 14, and the other end is located at the upper end surface of seal 14. This allows for communication between air inlet 121 and through hole 142. Preferably, through hole 142 is concentric with air inlet 121 to facilitate smoother air intake.

[0039] Among them, see Figure 3 、 5 6. A connecting channel 143 is provided between the mounting hole 141 and the air inlet 121. One end of the connecting channel 143 is connected to the air inlet 121, and the other end is connected to the air flow sensor 13. The mounting hole 141 is not directly provided next to the air inlet 121, but is connected through the connecting channel 143. The air flow sensor 13 provided in the mounting hole 141 can avoid being triggered by small disturbances, ensuring that the air flow sensor 13 is activated under normal inhalation conditions. The connecting channel 143 is a straight channel or a curved channel. If it is a straight channel, the aperture of the straight channel is smaller than the mounting hole 141 or the air inlet 121; if it is a curved channel, the curved channel can not only prevent the air flow sensor 13 from being easily contaminated by the atomized matrix or condensate, but also enhance the false triggering interference of the air flow sensor 13. The air inlet end of the connecting channel 143 is provided on the side wall of the air inlet 121, thereby improving the response speed of the air flow sensor 13.

[0040] Preferably, the mounting hole 141 is provided on a side of the sealing member 14 exposed to the mounting seat 12, that is, the side of the sealing member 14 facing the bottom of the housing 11. The mounting hole 141 is provided with a flange 145 at the port, so that after the airflow sensor 13 is installed in the mounting hole 141, the flange 145 can fix the airflow sensor 13. The flange 145 is located on the inner wall of the mounting hole 141 and extends toward the center of the mounting hole 141. In addition, the flange 145 is provided with a notch 146 to facilitate the installation of the airflow sensor 13 in the mounting hole 141. The diameter of the space enclosed by the flange 145 is smaller than the diameter of the mounting hole 141, so the notch 146 needs to be provided so that the airflow sensor 13 can be installed in the mounting hole 141. Among them, since the seal 14 is made of silicone, rubber, plastic and other products, and has certain deformation properties, the airflow sensor 13 can be installed to the mounting hole 141 from the cutout 146 of the flange 145. The flange 145 can fix the airflow sensor 13 installed to the mounting hole 141 to prevent the airflow sensor 13 from slipping out.

[0041] Preferably, see Figure 3 、 56. A groove 144 is provided on one end surface of the seal 14 located within the mounting cavity 122, so that the seal 14 can be assembled into the mounting cavity 122 to form the aforementioned connecting channel 143. The side surface of the seal 14 is sealedly connected to the mounting cavity 122. The groove 144 is provided on the inner end surface of the seal 14. Therefore, after the seal 14 is installed in the mounting cavity 122, a portion of the connecting channel 143 is formed between the groove 144 and the bottom surface of the mounting cavity 122. Furthermore, a channel is provided on the seal 14, one end of which communicates with the groove 144 and the other end communicates with the mounting hole 141. Therefore, after the seal 14 is installed in the mounting cavity 122, the channel formed by the groove 144 and the inner wall of the mounting cavity 14, together with the channel of the seal 14 itself, forms the connecting channel 143.

[0042] Preferably, the seal 14 is made of silicone, rubber or soft glue, which is beneficial to the sealing between the seal 14 and the installation cavity 122, and convenient for setting the installation hole 141, groove 144, etc. on the seal 14, and is easy to process.

[0043] See also Figure 2 、 3 , the mounting base 12 and the shell 11 form a accommodating chamber 15. The shell 11 is open at the upper end and closed at the lower end, forming a barrel-shaped structure. Therefore, the mounting base 12 is installed to the shell 11 from the open end, and the mounting base 12 is fixed at a position close to the upper end opening of the shell 11, so that an accommodating chamber 15 is formed between the mounting base 12 and the bottom of the shell 11. The mounting chamber 122 arranged at the lower end of the mounting base 12 is connected to the accommodating chamber 15. The mounting chamber 122 is an open design with the open end facing the accommodating chamber 15, which facilitates the routing of the airflow sensor 13. In addition, the accommodating chamber 15 can serve as part of the air intake channel, and the through hole 142 of the sealing member 14 is connected to the accommodating chamber 122, so that air can flow from the air inlet of the shell 11 through the accommodating chamber 15 into the through hole 142 and the air intake hole 121 respectively. The outer side of the mounting base 12 is in sealed contact with the inner wall of the shell 11 to ensure the air tightness of the accommodating chamber 15. Preferably, the outer side surface of the mounting seat 12 is in surface contact with the inner wall of the housing 11 to increase the airtightness of the contact.

[0044] Also, see Figure 2 、 3 The housing cavity 15 is provided with a circuit board 16 and a battery 17. The airflow sensor 13, which is mounted in the mounting cavity 122, and the circuit board 16 are both located within the housing cavity 15, thereby facilitating electrical connection between the circuit board 16 and the airflow sensor 13. Similarly, the battery 17 is mounted within the housing cavity 15, facilitating electrical connection between the circuit board 16, the airflow sensor 13, and other components.

[0045] See also Figure 2 、 3The mounting base 12 is provided with a mounting portion 125. The mounting portion 125 is an annular structure, and its outer contour matches the inner wall contour of the shell 11. When the mounting base 12 is fixed to the shell 11, the mounting portion 125 is snapped into the cavity inside the shell 11, and the mounting portion 125 and the shell 11 are sealed. Preferably, a snap-in protrusion 126 is provided on the outside of the mounting portion 125, and a snap-in groove is provided at a corresponding position on the inner wall of the shell 11. After the mounting base 12 is installed to the shell 11, the snap-in protrusion 126 is snapped into the snap-in groove, so that the mounting base 12 and the shell 11 are easily installed and can be installed by hand without the need for other tools.

[0046] Preferably, see Figure 2 、 3 The mounting portion 125 is a curved surface structure, which matches the inner wall of the outer shell 11. The inner wall of the outer shell 11 is also a curved surface structure, and the curvature rates of the two curved surface structures are the same. Therefore, the two curved surface structures can match each other to form a close surface contact, thereby ensuring the airtightness of the contact between the mounting seat 12 and the outer shell 11.

[0047] Preferably, see Figure 2 、 3 The mounting base 12 is provided with a mounting groove 123. One end of the circuit board 16 is inserted into the mounting groove 123. After the mounting base 12 is installed, the mounting groove 123 is provided on one end surface facing the accommodating cavity 15. The circuit board 16 is fixed in the mounting groove 123 by plugging one end, so that the circuit board 16 and the mounting base 12 form an integral whole. The entire whole is then installed in the housing 11, improving the convenience of installation and thus improving installation efficiency.

[0048] See also Figure 2 An extension tube 124 is provided at the outlet end of the mounting base 12, located at the air inlet 121. This extension tube 124 is located on the upper end surface of the mounting base 12. This extension tube 124 serves as an air intake component, connecting to the cigarette cartridge. When the device is assembled with the cigarette cartridge, the extension tube 124 plugs into the cigarette cartridge's air intake channel, effectively delivering air to the cartridge and creating a seal between the extension tube 124 and the cigarette cartridge's air intake channel.

[0049] See also Figure 2 、 3 Oil-absorbing cotton 18 is installed between the bottom of the installation cavity 122 and the sealing member 14. During installation, the oil-absorbing cotton 18 is first installed to the bottom of the installation cavity 122, and then the sealing member 14 is installed into the installation cavity 122. The oil-absorbing cotton 18 is placed close to the air inlet 121 and is connected to the air inlet 121, so that any leaked oil or condensate entering through the air inlet 121 can be absorbed by the oil-absorbing cotton 18.

[0050] An electronic atomizer, see Figure 1 、 27, comprising the power supply device 10 and the cigarette cartridge 20 used in conjunction with the power supply device 10. The air outlet end of the air inlet hole 121 of the power supply device 10 is connected to the air inlet end of the cigarette cartridge 20, so that air enters the atomization channel of the cigarette cartridge 20 through the power supply device 10.

[0051] A set distance is set between the upper end surface of the mounting seat 12 and the port of the shell 11, so that a connecting cavity 19 is formed between the port of the shell 11 and the upper end surface of the mounting seat 12. When the cigarette cartridge 20 is connected to the power supply device 10, the lower end of the cigarette cartridge 20 is inserted into the connecting cavity 19. Among them, the mounting seat 12 is located at the air outlet end of the air inlet 121, that is, the upper end of the mounting seat 12, and is provided with a first magnet 127. The first magnet 127 is located in the connecting cavity 19. A second magnet 21 is provided at the position corresponding to the lower end of the cigarette cartridge 20 and the first magnet 127. When the cigarette cartridge 20 is inserted into the connecting cavity 19, the first magnet 127 and the second magnet 21 contact each other, and the cigarette cartridge 20 is connected to the power supply device through the magnetic force of the first magnet 127 and the second magnet 21.

[0052] In addition, the mounting base 12 is provided with an electrical connection pin 128. One end of the electrical connection pin 128 extends to the upper end surface of the mounting base 12, and the other end extends to the lower end of the mounting base 12. The portion of the electrical connection pin 128 located at the upper end of the mounting base 12 directly contacts the cigarette cartridge 20 to provide power to the cigarette cartridge 20; the portion of the electrical connection pin 128 located at the lower end of the mounting base 12 is electrically connected to the circuit board 16. The cigarette cartridge 20 is provided with an electrical contact 22 that contacts the electrical connection pin 128. When the cigarette cartridge 20 is connected to the power supply device 10, the electrical connection pin 128 and the electrical contact 22 contact each other, allowing the power supply device 10 to provide power to the cigarette cartridge 20.

[0053] Compared to the prior art, the present invention provides a mounting cavity 122 on the lower end surface of the mounting base 12. Mounting cavity 122 communicates with an air inlet 121 extending through the upper and lower end surfaces of the mounting base 12. Mounting cavity 122 is used to mount a seal 14, which is provided with a mounting hole 141 for mounting the airflow sensor 13. The airflow sensor 13 is mounted to the mounting cavity 122 of the mounting base 12 via the seal 14, resulting in a simple and quick installation method that improves installation efficiency. Furthermore, the seal 14, through its inherent deformation properties, enhances the airtightness of the airflow sensor 13 during installation.

[0054] The above examples are merely used to further illustrate the technical content of the present invention for easier understanding by the reader.
