[0092] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be a centered element. When an element is considered to be "set on" another element, it may be directly set on the other element or there may also be a centered element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0094] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0095] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0096] See also Figures 1 to 5 In one embodiment of the present application, an atomizing device 1 is provided, which can atomize an atomizable substrate into an aerosol for a user to inhale. The atomizing device 1 can be an electronic cigarette, and correspondingly, the atomizable substrate can be a cigarette oil.

[0097] The atomizing device 1 comprises an atomizing assembly 100 and a liquid storage component 200, wherein Figure 4B FIG. 1 is a schematic diagram of the atomizing assembly 100 after removing the liquid storage component 200 from the atomizing device 1 . The atomizing assembly 100 includes a main shell 10 , a bottom shell 20 and a suction nozzle 30 .

[0098] The atomizer assembly 100 has a length direction L, and the main shell 10 includes a first end 10a and a second end 10b that are oppositely disposed along the length direction L. At least two receiving grooves 11 are disposed in the main shell 10, and each receiving groove 11 is configured to accommodate a liquid storage component 200, such as a cigarette cartridge. Figures 3 to 5 As shown, in some embodiments, the main shell 10 is provided with two receiving grooves 11 to place two liquid storage components 200. In this case, the cross section of the main shell 10 (hereinafter, the cross section refers to the plane perpendicular to the length direction L) can be roughly set to a rectangle. In other embodiments, the main shell 10 can also be provided with more than two receiving grooves 11, such as Figure 6 As shown, for example, the main shell 10 may be provided with three receiving grooves 11 to place three liquid storage components 200, and in this case, the cross-section of the main shell 10 may be roughly set to an arc-edged triangle. Among them, the cross-section of the receiving groove 11 may be circular or square. The cross-sectional shapes of each receiving groove 11 may be the same or different, that is, the main shell 10 may accommodate liquid storage components 200 of the same or different shapes. The type of atomizable matrix stored in each liquid storage component 200 is the same, and in this case, multiple liquid storage components 200 can increase the capacity of the atomizing device 1; the type of atomizable matrix stored in each liquid storage component 200 may also be different, and in this case, the atomizing device 1 can meet the user's needs for a variety of flavors. Further, as Figure 2 and Figure 3 As shown, the main shell 10 may also include a first opening 12 provided at the first end 10a and a second opening 13 provided at the second end 10b, and the number of the first opening 12 and the second opening 13 are consistent with the number of the receiving slots 11. A first opening 12 and a second opening 13 are respectively connected to the two ends of the receiving slot 11. When viewed from the length direction L, the second opening 13 covers the corresponding first opening 12. That is, along the width direction W perpendicular to the length direction L, the size of the second opening 13 is larger than the size of the corresponding first opening 12. Among them, when the number of the receiving slots 11 is two, the width direction W can be the arrangement direction of the two receiving slots 11; when the number of the receiving slots 11 is more than two, the width direction W can be any direction perpendicular to the length direction L.

[0099] like Figures 3 to 5 As shown, the liquid storage part 200 is provided with a first airway P1. The liquid storage part 200 may include a liquid storage part 201, a heating part 202 and a pair of conductive parts 205. The liquid storage part 201 is used to store an atomizable matrix, and the liquid storage part 201 is generally annular in structure and defines the first airway P1. The heating part 202 is arranged in the liquid storage part 201 and in contact with the liquid storage part 201. The heating part 202 is used to heat and atomize the atomizable matrix in the liquid storage part 201, thereby obtaining an aerosol that can be inhaled by the user. The pair of conductive parts 205 is electrically connected to the heating part 202. Further, the liquid storage part 200 may also include a sealing part located at at least one end of the liquid storage part 201. For example, the liquid storage part 200 may include a first sealing part 203 and a second sealing part 204 located at both ends of the liquid storage part 201, and the first sealing part 203 is closer to the suction nozzle 30 than the second sealing part 204. The pair of conductive parts 205 are exposed to the second sealing part 204. The sealing part can be the first sealing part 203 or the second sealing part 204. The first sealing part 203 and the second sealing part 204 can block the atomizable matrix overflowing from the liquid storage part 201, thereby reducing the risk of leakage of the atomizable matrix. In some embodiments, the liquid storage part 201 can be a liquid storage cotton. The heating part 202 can be a heating net or a heating wire, and the heating part 202 includes a first pin 2021 and a second pin 2022, and the first pin 2021 and the second pin 2022 are respectively connected to the pair of conductive parts 205. The conductive part 205 can be a conductive PIN pin made of a metal material. The first sealing part 203 and the second sealing part 204 can be silicone or rubber, and the first sealing part 203 and the second sealing part 204 can be provided with a fourth airway P4 connected to the first airway P1. Among them, oil-absorbing cotton (not shown) can be arranged between the first sealing part 203 and the liquid storage part 201, and oil-absorbing cotton (not shown) can also be arranged between the second sealing part 204 and the liquid storage part 201, and the oil-absorbing cotton can absorb the atomizable matrix overflowing from the liquid storage part 201.

[0100] The suction nozzle 30 is rotatably connected to the first end 10a, and the suction nozzle 30 can be covered on the first opening 12 of the main shell 10. An air inlet P0 is provided in the suction nozzle 30. When the suction nozzle 30 rotates relative to the main shell 10, the air inlet P0 can be selectively corresponding to one of the liquid storage components 200. That is, when the suction nozzle 30 rotates relative to the main shell 10, the air inlet P0 can be selectively communicated with the first airway P1 of one of the liquid storage components 200, thereby forming an air flow channel. Therefore, the aerosol formed after the atomizable matrix is ​​heated and atomized can be guided out through the air flow channel for the user to inhale. In some embodiments, the suction nozzle 30 includes an integrally arranged mounting portion 31 and a suction nozzle portion 32. The mounting portion 31 is rotatably connected to the first end 10a of the main shell 10. The suction nozzle portion 32 is convexly arranged on the mounting portion 31, and is located on the surface of the mounting portion 31 away from the main shell 10. The suction port P0 is arranged through the suction nozzle portion 32 and the mounting portion 31. The user can inhale at the mouthpiece 32, so that the aerosol generated after heating is discharged through the first airway P1 and inhaled by the user through the inhalation port P0. The shape of the mouthpiece 32 can be duckbill, round, oval, etc. that meets ergonomics.

[0101] like Figures 1 to 5 As shown, in some embodiments, the number of the containing tanks 11 is two. If the air inlet P0 corresponds to one of the liquid storage components 200, when the suction nozzle 30 rotates approximately 180 degrees relative to the main housing 10, the air inlet P0 can be switched to correspond to the other liquid storage component 200 (i.e., the working position of one liquid storage component is switched to the working position of another liquid storage component, thereby switching different liquid storage components 200 to work). Figure 6 and Figure 7 As shown, in other embodiments, the number of the receiving grooves 11 is three. If the air intake port P0 corresponds to one of the liquid storage components 200 at this time, when the suction nozzle 30 is rotated approximately 120 degrees relative to the main shell 10, the air intake port P0 can be switched to correspond to another liquid storage component 200.

[0102] Among them, Figures 1 to 3 As shown, the suction nozzle 30 rotates relative to the main shell 10, which can not only switch different liquid storage components 200 to work, but also make the first opening 12 and the second opening 13 appear on the suction nozzle 30 and the bottom shell 20 respectively (that is, switch to a liquid storage component replacement position, so that the user can replace the liquid storage component 200 in the receiving tank 11). Specifically, the user can take out the old liquid storage component 200 in the receiving tank 11 through the second opening 13, and insert and install the new liquid storage component 200 into the receiving tank 11 through the second opening 13. Figure 1 and Figure 2As shown, in some embodiments, the number of the receiving tanks 11 is two. If the air inlet P0 corresponds to one of the liquid storage components 200, when the suction nozzle 30 is rotated approximately 90 degrees relative to the main housing 10, it can be switched from a liquid storage component working position to a liquid storage component replacement position, so that the user can replace the liquid storage component 200 in the receiving tank 11. Figure 6 and Figure 7 As shown, in some embodiments, the number of the receiving tanks 11 is three, and if the air inlet P0 corresponds to one of the liquid storage components 200, when the suction nozzle 30 is rotated approximately 60 degrees relative to the main housing 10, it can be switched from a liquid storage component working position to a liquid storage component replacement position, so that the user can replace the liquid storage component 200 in the receiving tank 11. The first sealing portion 203 and the second sealing portion 204 of the liquid storage component 200 are configured to be arranged in the receiving tank 11 by interference fit, thereby reducing the risk of the liquid storage component 200 being separated from the receiving tank 11 during use.

[0103] The bottom shell 20 is rotatably connected to the second end 10b, and the bottom shell 20 can cover the second opening 13 of the main shell 10. When the suction nozzle 30 and the main shell 10 rotate relative to each other, the suction nozzle 30 is configured to move away from the bottom shell 20 along the length direction L, thereby reducing the friction between the suction nozzle 30 and the main shell 10 and improving the smoothness of the relative rotation between the suction nozzle 30 and the main shell 10.

[0104] In some embodiments, the suction nozzle 30 and the bottom shell 20 may be fixed together along the rotation direction of the suction nozzle 30 or the main shell 10. Figure 4A , Figure 4B , Figure 5 , FIG. 8A to FIG. 12 , the main shell 10 is provided with a main shell seat 14 at the first end 10a. The bottom shell 20 includes a bottom shell body 21 connected to the second end 10b and a bottom shell seat 22 fixed to the bottom shell body 21, and the bottom shell seat 22 is arranged in the main shell 10. The suction nozzle 30 also includes a rotating shaft 33. The rotating shaft 33 is rotatably arranged compared to the main shell seat 14, and the rotating shaft 33 can be inserted into the bottom shell seat 22 and fixed with the bottom shell seat 22 along the rotation direction, so that the suction nozzle 30 and the bottom shell 20 are fixed along the rotation direction. During use, the suction nozzle 30 and the bottom shell 20 are stationary, and the user can rotate the main shell 10 so that the suction nozzle 30 and the main shell 10 can rotate relative to each other. Of course, the user can also rotate one of the suction nozzle 30 and the bottom shell 20, which can also achieve relative rotation between the suction nozzle 30 and the main shell 10. Further, as Figure 5As shown, in some embodiments, the outer peripheral wall of the rotating shaft 33 is provided with a ridge 330, and the inner wall of the bottom shell seat 22 is provided with a groove 220, and the ridge 330 and the groove 220 can extend along the length direction L. The ridge 330 is arranged in the groove 220, so that the rotating shaft 33 and the bottom shell seat 22 are fixed in the rotation direction. In other embodiments, the outer peripheral wall of the rotating shaft 33 can also be provided with a groove, and correspondingly, the inner wall of the bottom shell seat 22 is provided with a ridge, and the cooperation of the ridge and the groove can also make the rotating shaft 33 and the bottom shell seat 22 fixed in the rotation direction. In other embodiments, along the rotation direction of the suction nozzle 30 or the main shell 10, the suction nozzle 30 and the bottom shell 20 may not be fixed. For example, when in use, the main shell 10 does not move, and the user can rotate the suction nozzle 30 and the bottom shell 20 respectively, so that the suction nozzle 30 and the main shell 10 and the bottom shell 20 and the main shell 10 can achieve relative rotation. In other embodiments, along the rotation direction of the suction nozzle 30 or the main shell 10 , the suction nozzle 30 and the bottom shell 20 may not be fixed to each other.

[0105] like FIG. 8A to FIG. 10 As shown, the suction nozzle 30 and the bottom shell 20 are movably connected along the length direction L, such as directly or indirectly, so that the suction nozzle 30 can move away from the bottom shell 20 along the length direction L. In some embodiments, the suction nozzle 30 may also include a suction nozzle seat 34 arranged around the rotating shaft 33. The suction nozzle seat 34 may be provided with a plurality of first protrusions 340, and the first protrusions 340 may be arranged to protrude in the direction toward the main shell 10, and the main shell seat 14 is provided with a plurality of first recesses 140 on one side facing the suction nozzle seat 34, and the first recesses 140 may be arranged to be recessed in the direction away from the suction nozzle 30. When the suction nozzle 30 and the main shell 10 rotate relative to each other, the plurality of first protrusions 340 may be respectively accommodated in the plurality of first recesses 140 or detached from the plurality of first recesses 140. It can be understood that, as Figure 8B As shown, when the plurality of first protrusions 340 are separated from the plurality of first recesses 140 respectively, the suction nozzle 30 and the main shell 10 are separated from each other along the length direction L; Fig. 8AAs shown, when the plurality of first protrusions 340 are respectively accommodated in the plurality of first recesses 140, the suction nozzle 30 and the main shell 10 are close to each other along the length direction L. Therefore, when the suction nozzle 30 and the main shell 10 rotate relative to each other, the suction nozzle 30 can move away from the main shell 10 or toward the main shell 10 along the length direction L, that is, away from the bottom shell 20 or toward the bottom shell 20 along the length direction L. In some specific embodiments, when the number of the accommodating grooves 11 is two, the number of the first protrusions 340 and the first recesses 140 are four respectively, and the four first protrusions 340 are evenly arranged along the rotation direction (that is, the angle formed by two adjacent first protrusions 340 and the rotation center is 90 degrees), and the four first recesses 140 are also evenly arranged along the rotation direction (that is, the angle formed by two adjacent first recesses 140 and the rotation center is 90 degrees). When two first protrusions 340 disposed at intervals are respectively accommodated in the corresponding first recesses 140, the atomizer 1 is in the liquid storage component working position; when the other two first protrusions 340 disposed at intervals are respectively accommodated in the corresponding first recesses 140, the atomizer 1 is in the liquid storage component replacement position. Therefore, the arrangement of the four first protrusions 340 and the four first recesses 140 defines four stable positions of the nozzle 30 during the relative rotation of the nozzle 30 and the main housing 10 (i.e., two liquid storage component working positions and two liquid storage component replacement positions).

[0106] When the suction nozzle 30 and the main shell 10 rotate relative to each other, the bottom shell 20 can also move away from the suction nozzle 30 along the length direction L, thereby reducing the friction between the bottom shell 20 and the main shell 10 and improving the smoothness of the relative rotation between the bottom shell 20 and the main shell 10. Fig. 8A , Figure 8B , Fig.11 and Fig.12 As shown, in some embodiments, the bottom shell seat 22 includes a plurality of second protrusions 221, which can be arranged to protrude in the direction toward the suction nozzle 30, and the main shell seat 14 is provided with a plurality of second recesses 141 on one side facing the bottom shell seat 22, which can be arranged to be recessed in the direction away from the bottom shell 21. When the suction nozzle 30 and the main shell 10 rotate relative to each other, the plurality of second protrusions 221 can be respectively accommodated in the plurality of second recesses 141 or separated from the plurality of second recesses 141. It can be understood that, as Figure 8B As shown, when the plurality of second protrusions 221 are separated from the plurality of second recesses 141, the bottom shell 20 and the main shell 10 are separated from each other along the length direction L; Fig. 8AAs shown, when the plurality of second protrusions 221 are respectively accommodated in the plurality of second recesses 141, the bottom shell 20 and the main shell 10 approach each other along the length direction L. Therefore, when the suction nozzle 30 and the main shell 10 rotate relative to each other, the bottom shell 20 can move away from the main shell 10 or toward the main shell 10 along the length direction L, that is, move away from the suction nozzle 30 or toward the suction nozzle 30 along the length direction L. In some specific embodiments, when the number of the accommodating grooves 11 is two, the number of the second protrusions 221 and the second recesses 141 are four respectively, and the four second protrusions 221 are evenly arranged along the rotation direction, and the four second recesses 141 are also evenly arranged along the rotation direction. The arrangement of the four second protrusions 221 and the four second recesses 141 defines four stable positions of the bottom shell 20 during the relative rotation of the suction nozzle 30 and the main shell 10. Among them, since the first recess 140 and the second recess 141 are respectively arranged on different sides of the main shell seat 14, in order to reduce the thickness of the main shell seat 14 itself, the first recess 140 and the second recess 141 can be staggered with each other when observed along the length direction L.

[0107] like Figures 3 to 5 As shown, in some embodiments, the atomizer assembly 100 may also include a first seal 60 and at least one second seal 61 disposed in the suction nozzle 30. The total number of the first seal 60 and the second seal 61 is consistent with the total number of the receiving grooves 11. The first seal 60 and the second seal 61 are configured to correspond to each receiving groove 11 one by one. The first seal 60 and the second seal 61 can seal the gap between the main shell 10 and the suction nozzle 30, reduce the risk of leakage of the atomizable matrix overflowing from the liquid storage component 200 through the above gap, and also reduce the risk of leakage of the generated aerosol through the above gap. Among them, the first seal 60 and the suction nozzle 30 are arranged in correspondence in the length direction L, and a second airway P2 connected to the air inlet P0 is provided. When the air inlet P0 can be selectively corresponding to one of the liquid storage components 200, the air inlet P0, the second airway P2 and the first airway P1 of the liquid storage component 200 form an airflow channel together. The second seal 61 is not provided with an air passage, so the first air passage P1 of the other liquid storage components 200 that do not correspond to the air inlet P0 will be closed by the second seal 61. The first seal 60 and the second seal 61 can be compressed when the suction nozzle 30 moves toward the bottom shell 20, thereby improving the sealing effect of the first seal 60 and the second seal 61. The material of the first seal 60 and the second seal 61 can be silicone or rubber.

[0108] like Fig. 8A and Figure 8BAs shown, the atomizer assembly 100 may further include a driving component 50, and the driving component 50 is disposed in the main housing 10. The driving component 50 has driving potential energy and is configured to drive the suction nozzle 30 to move toward the bottom housing 20 along the length direction L. Therefore, the suction nozzle 30, the main housing 10 and the bottom housing 20 are gathered along the length direction L to improve the sealing effect, thereby facilitating reducing the risk of leakage of the atomizable matrix of different liquid storage components 200 after switching.

[0109] In some embodiments, the atomizer assembly 100 may further include a fastening component 80. The fastening component 80 includes a head 81 and a tail 82 that are fixed to each other. The head 81 is disposed at one end of the rotating shaft 33, and the tail 82 is fixed in the rotating shaft 33. The driving component 50 is a helical cylindrical spring, and the helical cylindrical spring has a first end 51 and a second end 52 that are relatively arranged. Along the length direction L, the first end 51 is closer to the mouthpiece 30 than the second end 52. The bottom shell seat 22 is provided with a receiving groove 222, the first end 51 is abutted against the top of the receiving groove 222, and the second end 52 is abutted against the head 81. The helical cylindrical spring may be in a pre-compressed state initially. When the atomizer 1 switches from one stable position to another stable position (such as switching from a current liquid storage component working position to a liquid storage component replacement position), the first protrusion 340 disengages from the first recess 140 and the second protrusion 221 disengages from the second recess 141, and the helical cylindrical spring is further compressed. When reaching the replacement position of the liquid storage component 200, the restoring potential energy of the helical cylindrical spring can drive the suction nozzle 30 and the bottom shell 20 to move toward each other along the length direction L, so that the suction nozzle 30, the main shell 10 and the bottom shell 20 are retracted along the length direction L. Next, when the atomizer 1 switches from the current liquid storage component replacement position to another liquid storage component working position, the first protrusion 340 is separated from the first recess 140 again and the second protrusion 221 is separated from the second recess 141 again, and the spiral cylindrical spring is further compressed again. When reaching another liquid storage component replacement position, the return potential energy of the spiral cylindrical spring can drive the suction nozzle 30 and the bottom shell 20 to move toward each other along the length direction L, so that the suction nozzle 30, the main shell 10 and the bottom shell 20 are retracted along the length direction L. Among them, the fastening component 80 can be a pin or a pin column, which is fixed in the rotating shaft 33 by threaded engagement.

[0110] like Figure 4A and Figure 4BAs shown, the atomizer assembly 100 may also include a conductive component group 40. The conductive component group 40 is provided on the bottom shell 20 and is configured to be electrically connected to the liquid storage component 200 corresponding to the air inlet P0. For example, when in use, the suction nozzle 30 and the bottom shell 20 are stationary. When the main shell 10 is rotated approximately 180 degrees relative to the suction nozzle 30, it can be switched from a liquid storage component working position to another liquid storage component working position. At this time, the other liquid storage component 200 corresponds to the air inlet P0, so that the conductive component group 40 is changed to be electrically connected to the above-mentioned other liquid storage component 200. Among them, the conductive component group 40 may include two conductive components, each conductive component including a first conductive end 40a and a second conductive end 40b arranged oppositely. Since a pair of conductive parts 205 of the liquid storage component 200 are exposed to the second sealing part 204, it is convenient for the pair of conductive parts 205 to contact with a pair of conductive parts of the conductive component group 40. Among them, the atomizer assembly 100 may also include a power supply component 70 disposed in the bottom shell seat 22. The power supply component 70 includes a first electrode (not shown) and a second electrode (not shown) with opposite polarities. The first conductive end 40a of a conductive component is configured to be electrically connected to the first pin 2021 of the heating portion 202 through a conductive portion 205, and the second conductive end 40b of the conductive component is configured to be electrically connected to the first electrode of the power supply component 70. The first conductive end 40a of another conductive component is configured to be electrically connected to the second pin 2022 of the heating portion 202 through another conductive portion 205, and the second conductive end 40b of the conductive component is configured to be electrically connected to the second electrode of the power supply component 70 (it should be noted that Figure 4A The first pin 2021 and the second pin 2022 overlap, so only one of them is shown, the pair of conductive parts 205 overlap, so only one of them is shown, and the pair of conductive parts of the conductive part group 40 overlap, so only one of them is shown). Thus, the power supply component 70 can supply power to the liquid storage component 200 corresponding to the inhalation port P0 through the conductive part group 40, so that the heating part 202 heats and atomizes the atomizable matrix in the liquid storage part 201, thereby obtaining an aerosol that can be inhaled by the user. Among them, the conductive part group 40 can be a pair of conductive PIN needles made of metal. Further, a pair of conductive parts of the conductive part group 40 can be retracted compared to the bottom shell 20 (for example, the conductive part can be a spring pin). When the liquid storage part 200 is placed in the receiving groove 11, a pair of conductive parts of the conductive part group 40 can be extended compared to the bottom shell 20 and fully contact with the conductive part 205 of the liquid storage part 200. In some embodiments, the atomization assembly 100 also includes two buffers 71 arranged in the bottom shell seat 22. The two buffers 71 are respectively disposed at two ends of the power supply component 70 along the length direction L to buffer the collision of other components on the power supply component 70. The buffer 71 can be foam.

[0111] like Figure 4A and Figure 4BAs shown, in some embodiments, the atomizer assembly 100 may also include an airflow sensor 90 and a circuit board 91. The airflow sensor 90 is disposed at the bottom housing 21 and is configured to sense the airflow or air pressure change of the airflow channel. When the user inhales through the suction nozzle 30, the airflow of the airflow channel can activate the airflow sensor 90. The circuit board 91 is disposed at the bottom housing 21, and the conductive component group 40 is disposed on the circuit board 91. The circuit board 91 is electrically connected to the power supply component 70 and the airflow sensor 90 respectively. The second conductive end 40b of each conductive component of the conductive component group 40 can be electrically connected to the first electrode or the second electrode of the power supply component 70 through the circuit board 91. When the airflow sensor 90 senses the airflow or air pressure change of the airflow channel, the signal generated when the airflow sensor 90 senses the airflow or air pressure change of the airflow channel makes the electronic circuit in the circuit board 91 turn on, so that the power supply component 70 can be controlled to supply power to the liquid storage component 200 corresponding to the air inlet P0, so that the heating part 202 heats the atomizable matrix. In some embodiments, the airflow sensor 90 may be a microphone, and the power supply component 70 may be a cylindrical battery.

[0112] The atomizer assembly 100 may further include a third sealing member 62 disposed in the bottom housing 21. The circuit board 91 may be disposed on the side of the third sealing member 62 facing the main housing 10, and the airflow sensor 90 may be disposed in the third sealing member 62. The third sealing member 62 may be provided with a third air passage P3 that is respectively connected to the airflow channel and the airflow sensor 90, so that the airflow or air pressure change of the airflow channel can be sensed by the airflow sensor 90 through the third air passage P3. The material of the third sealing member 62 may be silicone or rubber.

[0113] In some embodiments, a connector 23 may be further provided on the bottom housing 21, and the connector 23 is electrically connected to the power supply component 70. The connector 23 may be connected to an external power source to charge the power supply component 70. The connector 23 may be a USB charging connector.

[0114] The above are only preferred embodiments of the present application and are 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.
