Description

Technical Field

[0001] The present application relates to the field of atomization technology, and more specifically, to an atomization device. Background Art

[0002] The atomizer mainly includes a power supply and an atomizer core. The power supply is used to supply power to the atomizer core, and the atomizer core is used to heat the liquid (usually a special liquid medicine) to form an aerosol for the user to inhale. The output power and air intake rate of the atomizer will directly affect the concentration and temperature of the aerosol. However, most atomizers on the market can usually only adjust one of the output power and the air intake rate, and the functions are relatively simple. Although there are a few atomizers that can adjust the output power and the air intake rate separately, the output power and the air intake rate need to be adjusted in turn, and usually, after adjusting the output power and the air intake rate in turn, the output power does not match the air intake rate, and it is necessary to adjust one of the output power or the air intake rate again until the output power matches the air intake rate. The adjustment process is very cumbersome. Utility Model Content

[0046] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0047] like Figures 1 to 4 or Figures 8 to 11As shown, an embodiment of the present application provides an atomization device, including a housing 100, a circuit assembly and a movable part 300. An air flow channel is provided inside the housing 100, and an air inlet 1121 communicating with the air flow channel is formed on the housing 100. The circuit assembly is arranged in the housing 100, and the circuit assembly includes a circuit carrier and an adjustment switch 400 movably arranged on the circuit carrier, and the adjustment switch 400 is used to adjust the power of the atomization core. The movable part 300 includes a main body 310 and a protrusion 320 connected to each other, the main body 310 is accommodated in the housing 100 and the main body 310 covers the air inlet 1121, and the main body 310 is connected to the adjustment switch 400. The protrusion 320 is arranged in the air inlet 1121, and the protrusion 320 can move in the air inlet 1121. At least two air inlet holes 301 are provided on the main body 310, and at least part of the air inlet holes 301 are communicated with the air inlet 1121. The main body 310 is configured to change the sum of radial cross-sectional areas of the plurality of air inlet holes 301 on the main body 310 connected to the air inlet 1121 when the protrusion 320 moves, and the main body 310 drives the adjustment switch 400 to move.

[0048] In the embodiment of the present application, the atomizer core is arranged on the air flow channel, and the atomizer core is electrically connected to the circuit carrier. The circuit carrier can be a circuit board or a chip, etc. For the convenience of description, the circuit carrier is taken as the circuit board 210 as an example for description.

[0049] Optionally, the air inlet hole 301 may be a round hole, a square hole or a hole of any other shape, which is not limited here.

[0050] Compared with the related art, the atomizer provided in the embodiment of the present application drives the protrusion 320 to move, so as to change the sum of the radial cross-sectional areas of the multiple air inlet holes 301 on the main body 310 that are connected to the air inlet 1121, thereby changing the size of the connecting area between the air inlet 1121 and the air flow channel in the housing 100 to adjust the air intake rate of the atomizer. When the protrusion 320 moves, the main body 310 can also drive the adjustment switch 400 to move, thereby adjusting the power of the atomizer core. In summary, the atomizer provided in the embodiment of the present application only needs to move the protrusion 320 to simultaneously adjust the air intake rate and output power (that is, the power of the atomizer core) of the atomizer, and the adjustment process is more convenient.

[0051] As can be seen from the above, the user only needs to slide the protrusion 320 to adjust the output power and air intake rate of the atomizing device at the same time, so as to adjust the concentration and temperature of the aerosol produced by the atomizing device, and the operation is more convenient. In addition, since only one movable part 300 is provided to adjust the output power and air intake rate of the atomizing device at the same time, the structure is simpler and the production cost is lower.

[0052] In some embodiments, the housing 100 is provided with an oil storage chamber for storing atomized liquid, which is usually a special liquid medicine, such as tobacco oil. Figure 2 , Figure 3 or Fig. 9 , Fig.10 As shown, the housing 100 includes an inner shell 120 and an outer shell 110, and the outer shell 110 is arranged around the outer periphery of the inner shell 120. The inner shell 120 has a chamber, and a suction nozzle 121 is connected to one side of the inner shell 120. The suction nozzle 121 and the inner shell 120 can be connected by means of snap connection, screw connection or gluing, or the suction nozzle 121 and the inner shell 120 can also be connected to form an integral structure by means of one-piece molding production. An opening connected to the chamber is provided on the other side of the inner shell 120 opposite to the suction nozzle 121, and the opening is covered with a first sealing structure 130, and the first sealing structure 130 and the inner wall of the chamber are arranged to form an oil storage chamber. Optionally, a second sealing structure 140 is also provided on one side of the inner shell 120 connected to the suction nozzle 121. The second sealing structure 140 is arranged around the outer periphery of the suction nozzle 121, and the second sealing structure 140 is located between the suction nozzle 121 and the side wall of the inner shell 120. The first sealing structure 130, the second sealing structure 140 and the inner wall of the chamber are arranged to form an oil storage chamber.

[0053] In some embodiments, Figure 3 , Figure 4 or Fig.10 , Fig.11 As shown, the atomizing device further includes a connecting pipe 150, which is located in the oil storage cavity and communicated with the suction nozzle 121. The first sealing structure 130 is provided with a first connecting hole 131, and the first connecting hole 131 is respectively connected to the connecting pipe 150 and the air inlet 1121. In some embodiments, the housing 110 has an inner cavity, the inner housing 120 is located in the inner cavity, and the air inlet 1121 is specifically opened on the side wall of the housing 110, and the air inlet 1121 is connected to the inner cavity. The connecting pipe 150 is connected to the inner cavity through the first connecting hole 131, so that the connecting pipe 150 is connected to the air inlet 1121. The main body 310 is specifically installed in the inner cavity of the housing 110 and covers the air inlet 1121. When at least part of the air inlet holes 301 on the main body 310 are connected to the air inlet 1121, the inner cavity can be connected to the air inlet 1121, so that the connecting pipe 150 is connected to the air inlet 1121. In this embodiment, the air flow channel includes an inner cavity, a first communication hole 131 and a communication pipe 150 .

[0054] The atomizing core is specifically disposed in the communicating pipe 150. Figure 3 or Fig.10As shown, a circuit board 210 and a battery 220 are installed in the inner cavity, and the atomizer core and the battery 220 are electrically connected to the circuit board 210 respectively, so as to power the atomizer core through the battery 220. The atomizer core is used to heat the atomized liquid in the oil storage chamber to form an aerosol, and discharge it from the housing 100 through the connecting pipe 150 and the suction nozzle 121 in turn for the user to inhale. The regulating switch 400 is mounted on the circuit board 210 and electrically connected to the circuit board 210, and the regulating switch 400 is electrically connected to the battery 220 through the circuit board 210. After the main body 310 is actuated, the regulating switch 400 can adjust the output power of the battery 220, and then adjust the power of the atomizer core, thereby adjusting the atomization rate of the atomizer core, so as to adjust the concentration and temperature of the aerosol generated by the atomizer core. The aerosol produced by the atomizer core is also the aerosol produced by the atomizing device. Exemplarily, a BOOST circuit (boost chopper circuit) is provided on the circuit board 210, and the regulating switch 400 is connected to the battery 220 through the BOOST circuit. When the sliding protrusion 320 is used to drive the main body 310 to move, the main body 310 can toggle the regulating switch 400 to adjust the output voltage of the battery 220, thereby adjusting the output power of the battery 220.

[0055] Optionally, the circuit board 210 is installed on one side of the first sealing structure 130 close to the air inlet 1121, and the circuit board 210 is penetrated by a second connecting hole 211 to facilitate external gas to enter the connecting pipe 150 through the air inlet 1121, the second connecting hole 211 and the first connecting hole 131 in sequence.

[0056] Alternatively, if Figure 3 or Fig.10 As shown, the inner wall of the outer shell 110 and the outer wall of the inner shell 120 are surrounded to form a receiving cavity, and the receiving cavity is used to receive the battery 220. The receiving cavity can be located on any side of the inner shell 120. For example, the receiving cavity can be located on the left side, right side, upper side or lower side of the inner shell 120, etc., which is not limited here.

[0057] In some optional embodiments, the protrusion 320 can move in the air inlet 1121. Specifically, the protrusion 320 can slide or rotate in the air inlet 1121 to drive the main body 310 to slide or rotate, thereby changing the sum of the radial cross-sectional areas of the multiple air inlet holes 301 on the main body 310 that are connected to the air inlet 1121. At the same time, the adjustment switch 400 is driven to move through the main body 310 to adjust the power of the atomization core.

[0058] In a possible design, the air inlet 1121 is extended along the first direction, and in the first direction, the length of the air inlet 1121 is greater than the length of the protrusion 320, and the protrusion 320 can reciprocate along the first direction at the air inlet 1121. In this arrangement, the air intake rate and output power of the atomization device can be adjusted by sliding the protrusion 320.

[0059] In the embodiment of the present application, the first direction may be a horizontal direction, a vertical direction, or an inclined direction. For ease of description, the following description is based on the example that the first direction is a horizontal direction.

[0060] In a possible design, at least two air inlet holes 301 include a large air hole 313 and a small air hole 314. That is to say, in the embodiment of the present application, the number of air inlet holes 301 can be two or more. When there are two air inlet holes 301, one of the air inlet holes 301 is a large air hole 313, and the other air inlet hole 301 is a small air hole 314; when there are more than two air inlet holes 301, at least one air inlet hole 301 is a large air hole 313, and another air inlet hole 301 is a small air hole 314. The large air hole 313 and the small air hole 314 are respectively located on both sides of the protrusion 320 along the first direction. It can be understood that, if Figure 5 or Fig.12 As shown, the radial area of ​​the large air hole 313 is greater than the radial area of ​​the small air hole 314. When the sliding protrusion 320 connects the large air hole 313 with the air inlet 1121, the regulating switch 400 is in the high-power gear, and when the sliding protrusion 320 connects the small air hole 314 with the air inlet 1121, the regulating switch 400 is in the low-power gear. It is worth noting that when the regulating switch 400 is in the high-power gear, the regulating switch 400 increases the power of the atomizer core, and when the regulating switch 400 is in the low-power gear, the regulating switch 400 decreases the power of the atomizer core. In this way, when the sliding protrusion 320 adjusts the air intake rate of the atomizer device, the power of the atomizer core adjusted synchronously can match the current air intake rate of the atomizer device.

[0061] In a possible design, the protrusion 320 can rotate at the air inlet 1121. The diameters of the multiple air inlet holes 301 on the main body 310 increase in sequence around the rotation axis of the protrusion 320. Fig.15As shown, a plurality of air inlet holes 301 are arranged at circumferential intervals around the rotation axis of the protrusion 320 on the main body 310, and the apertures of the plurality of air inlet holes 301 along the circumference of the rotation axis increase successively. The air inlet 1121 is connected to only one air inlet hole 301 at a time. The atomizer core power adjusted by the adjustment switch 400 is consistent with the aperture of the air inlet hole 301. That is, the atomizer core power adjusted by the adjustment switch 400 is positively correlated with the aperture of the air inlet hole 301 connected to the air inlet 1121. Exemplarily, when the protrusion 320 is rotated clockwise so that the air inlet hole 301 connected to the air inlet 1121 becomes an air inlet hole 301 with a larger aperture, the power of the atomizer core adjusted by the adjustment switch 400 becomes larger. Similarly, when the protrusion 320 is rotated counterclockwise so that the air inlet hole 301 connected to the air inlet port 1121 becomes an air inlet hole 301 with a smaller aperture, the power of the atomizer core adjusted by the adjustment switch 400 becomes smaller. In this setting, the air intake rate of the atomizer device and the power of the atomizer core in the atomizer device can be adjusted synchronously by rotating the protrusion 320.

[0062] In a possible design, a sealing member 600 is installed on the side of the main body 310 facing the air inlet 1121, and the side of the sealing member 600 facing away from the main body 310 abuts against the inner side of the shell 100. Specifically, the side of the sealing member 600 facing away from the main body 310 abuts against the inner side of the shell 110. The sealing member 600 is provided with a plurality of vias, and the plurality of vias are provided one-to-one with the plurality of air inlet holes 301, and each via is connected with the corresponding air inlet hole 301. By providing the sealing member 600, the sealing between the main body 310 and the inner side of the shell 100 can be improved, and the gas can be effectively prevented from entering the air flow channel from the gap between the main body 310 and the inner side of the shell 100, thereby improving the accuracy of the movable member 300 in regulating the gas. Optionally, the sealing member 600 can be made of materials such as silicone, rubber or plastic, which is not limited here.

[0063] In one possible design, Figure 5 or Fig.12As shown, the seal 600 is provided with two through holes, which are the first through hole 610 and the second through hole 620. The first through hole 610 is connected to the large air hole 313, and the second through hole 620 is connected to the small air hole 314. In this embodiment, when the main body 310 moves, the seal 600 is also driven to move, so that the first through hole 610 or the second through hole 620 on the seal 600 is connected to the air inlet 1121. Exemplarily, when the main body 310 moves in the positive direction of the first direction, the seal 600 moves synchronously with the main body 310, so that the second through hole 620 is connected to the air inlet 1121, and the small air hole 314 is connected to the air inlet 1121 through the second through hole 620. At this time, the large air hole 313 and the first through hole 610 are covered by the inner side of the housing 100. When the main body 310 moves in the opposite direction of the first direction, the seal 600 moves synchronously with the main body 310, so that the first via hole 610 is connected to the air inlet 1121, and the large via hole 313 is connected to the air inlet 1121 through the second via hole 620. At this time, the small via hole 314 and the second via hole 620 are covered by the inner side surface of the shell 100.

[0064] In a possible design, the sealing member 600 and the main body 310 are plugged into each other. This arrangement facilitates the installation of the sealing member 600 on the main body 310 and can improve the stability of the sealing member 600 installed on the main body 310.

[0065] In one example, if Figure 6 As shown, a limiting groove 315 is provided on one side of the main body 310 facing the air inlet 1121 , the sealing member 600 is inserted into the limiting groove 315 , the first through hole 610 is connected to the large air hole 313 , and the second through hole 620 is connected to the small air hole 314 .

[0066] In another example, Figure 5 , Figure 6 or Fig.12 , Fig.13 As shown, a first cylinder and a second cylinder are protruding from one side of the main body 310 toward the air inlet 1121 , the inner hole of the first cylinder is connected to the large air hole 313 , the inner hole of the second cylinder is connected to the small air hole 314 , the first cylinder is inserted into the first through hole 610 , and the second cylinder is inserted into the second through hole 620 .

[0067] In another example, Figure 5 and Figure 6As shown, a limiting groove 315 is provided on one side of the main body 310 facing the air inlet 1121. The limiting groove 315 has a bottom wall opposite to the air inlet 1121, and a first cylinder and a second cylinder are protruding from the bottom wall. The inner hole of the first cylinder is connected to the large air hole 313, and the inner hole of the second cylinder is connected to the small air hole 314. The sealing member 600 is inserted into the limiting groove 315, and the first cylinder is inserted into the first through hole 610, and the second cylinder is inserted into the second through hole 620. In this way, the stability of the sealing member 600 installed on the main body 310 can be effectively improved.

[0068] In one possible design, Figure 4 , Figure 5 or Fig.11 , Fig.12 As shown, a first annular convex strip 630 is provided on the side of the seal 600 facing the air inlet 1121, a first through hole 610 is formed with a first opening 611 on the side of the seal 600 facing the air inlet 1121, and a second through hole 620 is formed with a second opening 621 on the side of the seal 600 facing the air inlet 1121. Both the first opening 611 and the second opening 621 are located in the area surrounded by the first annular convex strip 630, and the first annular convex strip 630 abuts against the inner side surface of the housing 100. In this arrangement, the sealing between the main body 310 and the inner side surface of the housing 100 is improved by the abutment of the first annular convex strip 630 with the inner side surface of the housing 100, and at the same time, the contact area between the seal 600 and the housing 100 can be reduced to reduce the friction between the seal 600 and the housing 100, so that the seal 600 can move synchronously with the main body 310.

[0069] In one possible design, Figure 4 , Figure 5 or Fig.11 , Fig.12As shown, the side of the seal 600 facing the air inlet 1121 is further provided with a second annular ridge 640 and a third annular ridge 650, the second annular ridge 640 is arranged around the outer periphery of the first opening 611, and the third annular ridge 650 is arranged around the outer periphery of the second opening 621. When the large air hole 313 is opposite to the air inlet 1121 through the first through hole 610, the third annular ridge 650 abuts against the inner side surface of the housing 100; when the small air hole 314 is opposite to the air inlet 1121 through the second through hole 620, the second annular ridge 640 abuts against the inner side surface of the housing 100. In this arrangement, by providing the third annular ridge 650 and the fourth annular ridge, the contact area between the seal 600 and the housing 100 is further reduced, thereby further reducing the friction between the seal 600 and the housing 100. Since the second annular ridge 640 is arranged around the outer periphery of the first opening 611 and the third annular ridge 650 is arranged around the outer periphery of the second opening 621, when the large air hole 313 is opposite to the air inlet 1121 through the first via hole 610, the third annular ridge 650 abuts against the inner side surface of the shell 100, thereby ensuring the sealing between the second via hole 620 and the inner side surface of the shell 100; when the small air hole 314 is opposite to the air inlet 1121 through the second via hole 620, the second annular ridge 640 abuts against the inner side surface of the shell 100, thereby ensuring the sealing between the first via hole 610 and the inner side surface of the shell 100.

[0070] In one possible design, Figure 5 or Fig.12 As shown, the outer surface of the protrusion 320 is provided with an anti-skid structure 321. In this arrangement, by providing the anti-skid structure 321, the anti-skid effect when the user moves the protrusion 320 can be increased. For example, when the user moves the protrusion 320 with a finger, the friction between the protrusion 320 and the finger can be increased, so that the user can move the protrusion 320. Optionally, the anti-skid structure 321 may include a plurality of convex hulls, and the plurality of convex hulls are arranged at intervals on the outer surface of the protrusion 320.

[0071] Alternatively, in an optional embodiment, the anti-slip structure 321 includes a strip groove, which is arranged on the side of the protrusion 320 away from the main body 310, and the length direction of the strip groove is arranged at an angle with the first direction. Such an arrangement can also facilitate the user to move the protrusion 320. Optionally, the number of the strip grooves can be multiple, and the multiple strip grooves are arranged at intervals along the first direction, which has a better anti-slip effect.

[0072] In the embodiment of the present application, the regulating switch 400 movably disposed on the circuit carrier is specifically, the regulating switch 400 is installed on the circuit carrier, and at least a part of the structure of the regulating switch 400 is movable relative to the circuit carrier.

[0073] In one possible design, Figure 4 or Fig.11 As shown, the regulating switch 400 includes a fixed portion 410 and a sliding portion 420, the fixed portion 410 is mounted on the circuit carrier, the sliding portion 420 is movably connected to the fixed portion 410, and the sliding portion 420 is plugged into the main body 310. Exemplarily, a slot 312 is provided on the side of the main body 310 facing the sliding portion 420, and the sliding portion 420 is inserted into the slot 312. In this arrangement, when the main body 310 moves, the sliding portion 420 can be driven to move relative to the fixed portion 410, that is, the regulating switch 400 is driven to move to adjust the power of the atomizer core. It is worth noting that the sliding portion 420 is movably connected to the fixed portion 410, and specifically, the sliding portion 420 can be connected to the fixed portion 410 by sliding connection, rotation connection or other active connection. Optionally, the sliding portion 420 can be a cylindrical structure, a prismatic structure or other shape structure, and the shape of the slot 312 matches the shape of the sliding portion 420. For example, if the sliding portion 420 is a cylindrical structure, the slot 312 may be a cylindrical hole, and the protrusion 320 may be configured to be able to slide in the air inlet 1121. If the sliding portion 420 is a prismatic structure, the slot 312 may be a prismatic hole, and the protrusion 320 may be configured to be able to slide or rotate in the air inlet 1121. The following description is based on the example that the protrusion 320 can slide in the air inlet 1121.

[0074] In one example, the fixing portion 410 has a first area and a second area spaced along a first direction, the first area corresponds to the small air hole 314 on the main body 310, and the second area corresponds to the large air hole 313 on the main body 310. When the sliding portion 420 moves to the first area, it means that the adjustment switch 400 is in a low-power gear, the output power of the battery 220 is low, so that the power of the atomizer core is low, and at the same time, the small air hole 314 is connected to the air inlet 1121, and the air intake rate of the air flow channel is slow. At this time, the concentration of the aerosol generated by the atomizer device is low and the temperature is also low, and the atomizer device is in a mouth-inhalation mode. When the sliding portion 420 moves to the second area, it means that the adjustment switch 400 is in a high-power gear, the output power of the battery 220 is high, so that the power of the atomizer core is high, and at the same time, the large air hole 313 is connected to the air inlet 1121, and the air intake rate of the air flow channel is fast. At this time, the concentration of the aerosol generated by the atomizer device is high and the temperature is also high, and it is in a light lung inhalation mode. It can be seen from this that the experience mode of the atomization device provided in the embodiment of the present application is richer.

[0075] In some embodiments, the circuit carrier is a circuit board 210, and the circuit board 210, the fixing portion 410 and the main body 310 are sequentially arranged along the third direction, and the fixing portion 410 and the main body 310 are both located on the side of the circuit board 210 facing the air inlet 1121. The sliding portion 420 is located on the side of the fixing portion 410 facing the main body 310 and inserted into the slot 312, and the protruding portion 320 is located on the side of the main body 310 away from the fixing portion 410. The third direction is arranged at an angle to the first direction, and illustratively, the third direction is arranged perpendicular to the first direction.

[0076] In one possible design, Figure 4 and Figure 5 As shown, a plurality of limiting portions 311 are provided on one side of the main body 310 facing the fixing portion 410, and the plurality of limiting portions 311 are respectively located on both sides of the fixing portion 410 in the second direction, the second direction is arranged at an angle with the first direction, and each limiting portion 311 is in contact with the circuit carrier. It is worth noting that the plurality of limiting portions 311 are respectively located on both sides of the fixing portion 410 in the second direction, specifically, at least one limiting portion 311 is located on one side of the fixing portion 410 in the second direction, and at least one limiting portion 311 is located on the other side of the fixing portion 410 in the second direction. Exemplarily, when there are two limiting portions 311, the two limiting portions 311 are respectively located on both sides of the fixing portion 410 in the second direction. When there are three limiting portions 311, one of the limiting portions 311 is located on one side of the fixing portion 410 in the second direction, and the other two limiting portions 311 are located on the other side of the fixing portion 410 in the second direction. In this arrangement, since the plurality of limiting portions 311 are respectively located on both sides of the fixing portion 410 in the second direction, the limiting action between the limiting portions 311 and the fixing portion 410 can effectively prevent the main body 310 from deflecting in the second direction, so that the main body 310 can move more accurately along the first direction. Furthermore, since the plurality of limiting portions 311 are in contact with the circuit board 210, the distance between the main body 310 and the circuit board 210 is always equal to the thickness of the limiting portions 311.

[0077] Exemplarily, when the main body 310 and the circuit board 210 are arranged at intervals along the third direction, in this embodiment, the distance between the main body 310 and the circuit board 210 can always be equal to the length of the limiting portion 311 in the third direction. In this way, the pressure exerted by the main body 310 on the fixing portion 410 can be effectively reduced. On the one hand, it can provide a better protection for the fixing portion 410, that is, it can provide a better protection for the regulating switch 400; on the other hand, it can reduce the friction between the main body 310 and the fixing portion 410, so as to facilitate the main body 310 to move along the first direction through the protrusion 320. In the embodiment of the present application, the first direction, the second direction and the third direction are arranged at an angle to each other. Optionally, the first direction, the second direction and the third direction are arranged perpendicular to each other.

[0078] In one possible design, Figure 7 or Fig.14 As shown, a guide groove 1122 is provided on the inner wall of the housing 100, and the main body 310 is slidably installed in the guide groove 1122 along the first direction. In this arrangement, by providing the guide groove 1122, the stability of the movement of the main body 310 relative to the housing 100 is improved, so that the user can drive the main body 310 to move through the sliding protrusion 320.

[0079] In some optional embodiments, the guide groove 1122 is specifically arranged on the inner wall of the housing 110. Exemplarily, the housing 110 includes a base 112 and an upper shell 111, the base 112 is installed below the upper shell 111, the base 112 and the upper shell 111 surround and form an inner cavity of the housing 110, and the guide groove 1122 and the air inlet 1121 are specifically arranged on the base 112.

[0080] Alternatively, if Fig. 9 and Fig.10 As shown, the inner cavity is also equipped with an airflow sensor 500, which is specifically installed above the base 112. The airflow sensor 500 is electrically connected to the circuit board 210, and the airflow sensor 500 is used to detect the airflow in the airflow channel, and control the power supply state of the battery 220 to the atomizer core according to the detection result. Specifically, the airflow sensor 500 specifically controls the power supply state of the battery 220 to the atomizer core by detecting the airflow in the inner cavity. When the airflow sensor 500 detects that there is airflow passing through the inner cavity, the airflow sensor 500 controls the battery 220 to supply power to the atomizer core through the circuit board 210, so that the atomizer core starts working; when the airflow sensor 500 does not detect that there is airflow passing through the inner cavity, the airflow sensor 500 can cut off the power supply of the battery 220 to the atomizer core through the circuit board 210, so that the atomizer core stops working, thereby turning off the atomization device.

[0081] In some embodiments, Figure 8 and Fig. 9 As shown, the atomizer device further includes an indicator light 160, which is installed in the housing 110 and electrically connected to the circuit board 210. When the atomizer core is working, the indicator light 160 emits light. The housing 110 is provided with a light-transmitting window 170, and the indicator light 160 is opposite to the light-transmitting window 170, so that the light emitted by the indicator light 160 can be emitted through the light-transmitting window 170. In this way, the aesthetics of the atomizer device is improved to a certain extent.

[0082] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
