[0040] The present invention proposes an aerosol generator, please refer to Figure 1-10 , the aerosol generator includes a shell 1, a sliding member 2 and an adjusting component 3. The shell 1 is provided with an air inlet 111, and the sliding member 2 is slidably mounted on the shell 1 corresponding to the air inlet 111. The adjusting component 3 is provided with a second transmission part 5 adapted to the first transmission part 4 at one end, and a retractable button 33 at the other end. The adjusting component 3 is rotatably mounted on the shell 1, and the second transmission part 5 is adapted to be connected with the first transmission part 4. When the button 33 extending out of the shell 1 is rotated, the button 33 drives the second transmission part 5 to rotate and cooperate with the first transmission part 4, so that the sliding member 2 slides in the shell 1 and at least partially closes the air inlet 111. In this embodiment, the transmission cooperation between the sliding member 2 and the adjusting component 3 is achieved by rotating the retractable button 33, thereby achieving precise air adjustment. At the same time, the retractable adjustment button 33 is convenient for the user to store the button 33, and can also prevent the button 33 from being triggered by mistake.

[0041] In some embodiments, Figure 3 and Figure 8As shown, the housing 1 includes a shell 11 and a bracket 12. The shell 11 is a hollow structure, and the side wall of the shell 11 is provided with the air inlet 111. The bracket 12 is installed in the shell 11, and the bracket 12 is provided with a slide groove 123 for installing the sliding member 2 and a mounting hole 121 for installing the adjustment component 3. The shell 11 is provided with a through hole 112 corresponding to the mounting hole 121. When the bracket 12 is installed in the shell 11, the mounting hole 121 is exposed from the through hole 112, and the button 33 passes through the mounting hole 121 and the through hole 112 in sequence and extends out of the shell 11. The opening direction of the slide groove 123 faces the air inlet 111, and is connected to the air inlet 111. The shape of the sliding member 2 is adapted to the shape of the slide groove 123. When the sliding member 2 is accommodated in the slide groove 123, the outer periphery of the sliding member 2 fits with the inner wall of the slide groove 123, so that the sliding member 2 is limited by the inner wall of the slide groove 123. Preferably, the sliding member 2 is fitted with the inner wall of the housing 11 from the side exposed from the opening of the slide groove 123. When the sliding member 2 slides in the slide groove 123, the sliding member 2 slides in the inner wall of the housing 11, so that when the sliding member 2 closes the air inlet 111, the air flow from the gap between the sliding member 2 and the housing 11 is reduced. In practical applications, a sealing member can also be provided on the side of the sliding member 2 facing the inner wall of the housing 11, or a sealing member can be provided on the inner wall of the housing 11 surrounding the air outlet, so that the gap between the sliding member 2 and the housing 11 can be reduced by the sealing member, and the sliding resistance between the sliding member 2 and the housing 11 can also be increased, thereby enhancing the user's adjustment feel.

[0042] In some embodiments, please refer to Figure 3 and Figure 4The adjustment assembly 3 includes a sleeve 31, a first elastic member 32 and a button 33. The sleeve 31 is rotatably mounted in the mounting hole 121. The sleeve 31 includes a sleeve 311 and a cover 312. The sleeve 311 is adapted to the shape and size of the mounting hole 121, and the sleeve 311 is coaxially mounted with the mounting hole 121. When the sleeve 311 rotates driven by the button 33, the sleeve 311 rotates in the mounting hole 121 with the central axis as the rotation axis. Since the sleeve 311 is adapted to the mounting hole 121, the outer periphery of the sleeve 311 fits the inner wall of the mounting hole 121, and the sleeve 311 can be limited by the inner wall of the mounting hole 121. Preferably, the hole wall of the mounting hole 121 is protruded with a limiting rib 124 extending in the radial direction, and the outer periphery of the sleeve 311 is provided with a first annular limiting groove 3112 extending in the radial direction. When the sleeve 311 is accommodated in the mounting hole 121, the limiting rib 124 is accommodated in the first annular limiting groove 3112 and can rotate along the first annular limiting groove 3112. Through the cooperation between the limiting rib 124 and the first annular limiting groove 3112, not only can the rotation of the sleeve 311 be guided, but also the displacement of the sleeve 311 in the axial direction can be limited to prevent the sleeve 311 from escaping from the mounting hole 121. Preferably, the limiting rib 124 is detachably connected to the bracket 12, that is, the hole wall of the mounting hole 121 is provided with an arc hole 122 adapted to the limiting rib 124, and the limiting rib 124 is inserted into the arc hole 122 from the outside of the bracket 12, and protrudes into the mounting hole 121, and finally partially inserted into the first annular limiting groove 3112. In practical applications, the limiting rib 124 can be one, two or more. The number of the first annular limiting grooves 3112 corresponds to the number of the limiting ribs 124. Of course, the limiting ribs 124 can also be provided on the sleeve 311, and correspondingly, the first annular limiting grooves 3112 are provided on the hole wall of the mounting hole 121.

[0043] In some embodiments, the adjustment component 3 may further include a damping member 6. The damping member 6 is disposed between the sleeve 311 and the mounting hole 121 to increase the rotational resistance between the sleeve 311 and the mounting hole 121, thereby increasing the adjustment feel of the button 33. Preferably, the damping member 6 is annular, and the annular damping member 6 is sleeved on the outer periphery of the sleeve 311. Correspondingly, the outer periphery of the sleeve 311 is provided with a second annular limiting groove 3113 adapted to the damping member 6. The damping member 6 is partially accommodated in the second annular limiting groove 3113, and partially protrudes out and elastically abuts against the hole wall of the mounting hole 121. The damping member 6 is made of soft rubber material, such as silica gel, rubber or silicone rubber. The friction between the sleeve 311 and the hole wall of the mounting hole 121 is increased by the elastic abutment between the damping member 6 and the hole wall of the mounting hole 121.

[0044] In some embodiments, Figure 4 as well as Figure 8-10 As shown, the sleeve 311 is provided with a mounting groove 3111, and the opening of the mounting groove 3111 faces the sliding member 2. One end of the cover body 312 covers the opening of the mounting groove 3111, and forms an active cavity 313 with the mounting groove 3111. That is, the side walls and bottom walls of the cover body 312, the mounting groove 3111 together form the cavity wall of the active cavity 313. The button 33 passes through the bottom wall of the mounting groove 3111 and is partially accommodated in the active cavity 313. The other end of the cover body 312 protrudes away from the sleeve 311 to have the second transmission part 5. One end of the second transmission part 5 that is away from the cover body 312 protrudes into the slide groove 123 and is adaptively connected to the first transmission part 4. Preferably, the second transmission part 5 is a screw rod, one end of which is vertically connected to the cover body 312, and the other end protrudes into the slide groove 123. Correspondingly, the first transmission part 4 is a threaded hole adapted to the screw. The threaded hole passes through the slider 2 and is coaxially arranged with the screw. At the same time, the axial direction of the threaded hole is perpendicular to the axial direction of the air inlet hole 111, so that when the slider 2 slides along the axial direction of the threaded hole, the sliding direction is perpendicular to the axial direction of the air inlet hole 111, so that the slider 2 can maintain the direction of covering the air inlet hole 111.

[0045] Specifically, the screw rod passes through one side wall of the slide groove 123 and protrudes into the slide groove 123, and is adapted to pass through the threaded hole, and then passes through the other side wall of the slide groove 123, so as to be mounted in the slide groove 123. Correspondingly, the two opposite side walls of the slide groove 123 are respectively provided with rotation holes, and the screw rod passes through the two rotation holes in sequence and can rotate relative to the slide groove 123. When the button 33 is rotated, the screw rod rotates under the drive of the sleeve 311, and meshes with the threaded hole for transmission, thereby driving the sliding member 2 to move along the axial direction of the screw rod, so that the sliding member 2 slides relative to the air inlet 111 in the slide groove 123. The sliding member 2 gradually closes the air inlet 111 as the screw rod rotates, so that the air inlet 111 gradually decreases, and the air intake volume also decreases accordingly. On the contrary, when the screw rod rotates in the opposite direction, the sliding member 2 gradually opens the air inlet 111, and the air inlet 111 gradually becomes larger, and the air intake volume also increases accordingly. In this embodiment, the sliding air regulation of the sliding member 2 is achieved through the transmission cooperation between the screw rod and the threaded hole, which makes it easy to control the air regulation amount and achieve precise air regulation.

[0046] It is worth noting that the first transmission part 4 and the second transmission part 5 are not limited to the above structure, and they can also be other transmission modes. For example, the first transmission part 4 adopts a rack, and correspondingly, the second transmission part 5 adopts an adapted gear. When the gear rotates, the rack meshes with the size and slides in the slide groove 123, thereby adjusting the size of the air inlet 111. Smooth adjustment is achieved through gear transmission.

[0047] In some embodiments, Figure 5 and Figure 8 As shown, the cover body 312 includes a cover plate 3121 and a side plate 3122, and the cover plate 3121 is adapted to the opening of the mounting groove 3111 and closes the opening of the mounting groove 3111. The side plate 3122 is formed by vertically bending the edge of the cover plate 3121, and is adapted to the outer peripheral shape and size of the sleeve 311. Since the sleeve 311 is to rotate with the key 33, the sleeve 311 is a cylindrical structure, and accordingly, the side plate 3122 is surrounded by an adaptive ring. The side plate 3122 is tightly sleeved on the outer periphery of the sleeve 311 to fasten the cover body 312 to the sleeve 311. Preferably, the side plate 3122 is provided with a limiting groove extending in the axial direction (not shown in the figure), and the outer periphery of the sleeve 311 is protruded with a limiting strip 3119 extending in the axial direction. When the cover body 312 covers the sleeve 311, the limiting strip 3119 is inserted into the limiting groove. Through the cooperation between the limiting strip 3119 and the limiting groove, not only the cover body 312 can be limited, but also radial displacement between the sleeve 311 and the cover body 312 can be prevented to cause thread slippage. Of course, the convex strip can also be set on the side plate 3122, and the limiting groove can also be set on the sleeve 311. In practical applications, other limiting structures can also be set, such as a thread matching structure opposite to the rotation direction.

[0048] In some embodiments, the second transmission part 5 is vertically connected to the cover plate 3121 and protrudes into the mounting groove 3111, and a mounting column 3123 protrudes from the side of the cover plate 3121 away from the second transmission part 5. The first elastic member 32 adopts a spring adapted to the mounting column 3123. One end of the first elastic member 32 is tightly sleeved on the mounting column 3123, and the other end is elastically abutted against the button 33. The first elastic member 32 is fixed and limited by the mounting column 3123.

[0049] In some embodiments, Figure 4-8As shown, the button 33 includes a knob 331 and a pressure rod 332. The knob 331 includes a push rod 333 and a cap body 334. One end of the push rod 333 is fixedly connected to the cap body 334. In practical applications, the cap body 334 is a round cap structure coaxial with the push rod 333, and a connecting column 3341 protrudes toward the push rod 333, and the push rod 333 is provided with a connecting hole (not shown in the figure) adapted to the connecting column 3341. The connecting column 3341 is fastened and inserted into the connecting hole to fasten the cap body 334 to the push rod 333. The other end of the push rod 333 extends into the active cavity 313 and can slide in the active cavity 313. Correspondingly, one end of the sleeve 311 away from the cover body 312 (i.e., the bottom wall of the mounting groove 3111) is provided with a position avoidance hole 3114 for the push rod 333 to pass through. A plurality of second ridges 3331 are arranged at intervals along the circumferential direction on one end of the push rod 333 accommodated in the sleeve 311. The length direction of each second ridge 3331 extends along the axial direction of the push rod 333. The plurality of second ridges 3331 are centrally symmetrically distributed about the central axis of the push rod 333. The plurality of second ridges 3331 surround the push rod 333 to form an annular structure, the outer diameter of which is larger than the aperture of the avoidance hole 3114. The annular structure formed by the second ridges 3331 abuts against the end surface of the avoidance hole 3114 to limit the knob 331, thereby preventing the knob 331 from being ejected from the active cavity 313 under the action of the first elastic member 32.

[0050] Correspondingly, the inner wall of the sleeve 311, that is, the cavity wall of the active cavity 313, is provided with a plurality of second guide grooves 3118 adapted to the second convex strips 3331. The second convex strips 3331 are respectively accommodated in the corresponding second guide grooves 3118. When the cap body 334 is pressed, the cap body 334 pushes the push rod 333 to slide toward the pressing rod 332. Under the action of the second convex strips 3331, the push rod 333 slides along the second guide grooves 3118. Through the cooperation between the second convex strips 3331 and the second guide grooves 3118, the push rod 333 is guided and limited, so as to prevent the push rod 333 from sliding and deflecting or rotating.

[0051] The pressure rod 332 includes a pressure rod body 3321, and the pressure rod body 3321 is a rotating body structure, which is coaxially installed in the sleeve 311. A receiving groove 3324 adapted to the first elastic member 32 is provided on one side of the pressure rod body 3321 facing the mounting column 3123, and one end of the first elastic member 32 away from the mounting column 3123 is accommodated in the receiving groove 3324 and elastically abuts against the pressure rod body 3321. That is, the first elastic member 32 is always in a pre-stressed state. A plurality of first convex strips 3322 are provided on the outer periphery of the pressure rod body 3321, and each first convex strip 3322 extends along the axial direction of the pressure rod body 3321. The plurality of first convex strips 3322 are centrally symmetrically distributed with respect to the central axis of the pressure rod body 3321 to form a first limiter.

[0052] In some embodiments, a first arc-shaped guide surface 3323 is provided on one side of the pressure rod 332 facing the push rod 333, and a second arc-shaped guide surface 3332 is provided on one side of the push rod 333 facing the pressure rod 332. Both the first arc-shaped guide surface 3323 and the second arc-shaped guide surface 3332 are adapted to the rotation trajectory of the pressure rod 332. When the push rod 333, driven by the cap body 334, supports the pressure rod 332 in the direction of the first elastic member 32, the pressure rod 332 slides toward the first elastic member 32 and compresses the first elastic member 32, and is subjected to the elastic force of the first elastic member 32. At this time, under the action of the first arc-shaped guide surface 3323 and the second arc-shaped guide surface 3332, the pressure rod 332 produces radial displacement relative to the push rod 333 and rotates. Preferably, the first arc-shaped guide surface 3323 is provided at one end of a plurality of the first convex strips 3322 facing the push rod 333, and the second arc-shaped guide surface 3332 is provided at one end of a plurality of the second convex strips 3331 facing the pressure rod 332. When the push rod 333 slides under pressure, the second convex strips 3331 support the pressure rod 332, and under the combined action of the second arc-shaped guide surface 3332 and the first arc-shaped guide surface 3323 and the resilience of the first elastic member 32, the pressure rod 332 rotates while sliding along the axial direction of the sleeve 311.

[0053] In some embodiments, the inner wall of the sleeve 311, that is, the cavity wall of the active cavity 313, is provided with a plurality of protrusions 3115. The length direction of the protrusions 3115 extends along the axial direction of the sleeve 311. The plurality of protrusions 3115 are distributed at intervals along the circumference of the sleeve 311, and are centrally symmetrically distributed with respect to the central axis of the sleeve 311. The interval space between two adjacent protrusions 3115 forms a first guide groove 3116 adapted to the first convex strip 3322. That is, the inner wall of the sleeve 311 forms the bottom wall of the first guide groove 3116, and the opposite sides of the adjacent protrusions 3115 form the two side walls of the first guide groove 3116. The number of the first guide grooves 3116 is set corresponding to the number of the first convex strips 3322. Since the number of the protrusions 3115 is the same as the number of the first guide grooves 3116, the number of the protrusions 3115 is the same as the number of the first ridges 3322. For example, if there are four first ridges 3322 and the angle between adjacent ridges is 45 degrees, then there are also four protrusions 3115, and the four protrusions 3115 are also evenly distributed on the inner wall of the sleeve 311. When the pressure rod 332 slides toward the push rod 333 under the action of the first elastic member 32, each first ridge 3322 is respectively accommodated in the corresponding first guide groove 3116 and slides along the corresponding first guide groove 3116.

[0054] Preferably, the second guide groove 3118 is provided on the protrusion 3115. That is, the protrusion 3115 is provided with the second guide groove 3118 matched with the second convex strip 3331 along the axial direction, so that the space on the inner wall of the sleeve 311 can be fully utilized. Further, the groove width of the first guide groove 3116 is compatible with the second convex strip 3331 at the same time, so that the second convex strip 3331 can be accommodated in the first guide groove 3116. That is to say, both the first guide groove 3116 and the second guide groove 3118 can be used to form a slot for the second convex strip 3331 to slide. In this way, the number of the second convex strips 3331 can be increased, which not only makes the sliding of the push rod 333 itself more stable, but also increases the contact area between the push rod 333 and the pressure rod 332, so that the push rod 333 is more stable when pushing the pressure rod 332, and the pressure rod 332 is more evenly stressed.

[0055] Further, if Figure 5As shown, the end of the protrusion 3115 away from the button 33 is provided with a clamping portion 3117. The clamping portion 3117 is in a step shape, which includes a lower surface 3117a, a higher surface 3117b and a higher surface 3117c, which are sequentially connected to form a Z-shaped step. The lower surface 3117a and the higher surface 3117c are both facing the direction of the first elastic member 32. When the pressure rod 332 is acted upon by the push rod 333 and the first elastic member 32, the first ridge 3322 slides out of the corresponding first guide groove 3116 and rotates along the lower surface 3117a to the junction of the lower surface 3117a and the height surface 3117b. At this time, the pressure applied to the cap body 334 is cancelled. Under the action of the rebound force of the first elastic member 32, the first ridges 3322 of the pressure rod 332 respectively abut against the junction of the lower surface 3117a and the height surface 3117b of the corresponding locking portion 3117 and remain locked. At this time, the cap body 334 retracts into the shell 1 and the button 33 is stored. When the cap body 334 is continuously pressed, the pressure rod 332 first moves toward the direction of the first elastic member 32 and rotates at the same time under the joint action of the push rod 333 and the first elastic member 32. At this time, each first ridge 3322 disengages from the corresponding locking portion 3117 and rotates along the higher surface 3117c until it slides into the first guide groove 3116 adjacent to the higher surface 3117c; at this time, the pressure applied to the cap body 334 is canceled, and the pressure rod 332 slides toward the push rod 333 under the action of the rebound force of the first elastic member 32, and each first ridge 3322 slides along the first guide groove 3116 respectively, and pushes the push rod 333 to slide toward the end of the sleeve 311 away from the cover body 312, until the second ridge 3331 on the push rod 333 abuts against the end face of the avoidance hole 3114 and remains in a locked state. At this time, the cap body 334 extends out of the shell 1, and the button 33 protrudes for user operation. In this way, the user can eject the button from the housing when he needs to adjust the air intake, and can retract the button from the housing when he does not need to use it. This can not only maintain the integrity of the device and facilitate the user's grip, but also prevent the protruding button from being misoperated. On the other hand, by setting the knob to extend and retract in the active cavity of the housing, and by setting a snap-fit ​​portion and a position-avoiding hole in the housing to lock the extended or retracted state of the knob, the knob can drive the housing as a whole to rotate in the mounting hole when it is locked with the housing, thereby achieving the purpose of adjusting the air. In other words, the extension and retraction of the button of this embodiment and the rotation of the adjustment component as a whole are independent of each other and do not interfere with each other, which is convenient for the user to operate.

[0056] Preferably, please refer to Figure 4 and Fig.10, the adjustment component 3 also includes a second limiting member 34 provided with a limiting ring 341. The second limiting member 34 is in the shape of a rod. One end of the second limiting member 34 is fastened and inserted into the knob 331 and is coaxial with the knob 331. The pressure rod 332 is provided with a limiting through hole 3325 coaxial with the second limiting member 34, and the aperture of the limiting through hole 3325 is larger than the outer diameter of the second limiting member 34. The other end of the second limiting member 34 passes through the limiting through hole 3325 and can be slidably extended into the pressure rod 332 and accommodated in the accommodating groove 3324. The limiting ring 341 is accommodated in the pressure rod 332, and the outer diameter of the limiting ring 341 is larger than the aperture of the limiting through hole 3325. When the knob 331 is retracted into the housing 1, the limiting ring 341 abuts against the end surface of the limiting through hole 3325. A pulling force toward the pressure rod 332 is applied to the knob 331 through the limiting ring 341 , so that when the pressure rod 332 is pressed against the engaging portion 3117 , the knob 331 will not extend out of the housing 1 and will remain stored in the housing 1 .

[0057] Furthermore, the adjustment assembly 3 also includes a second elastic member 35. The mounting column 3123 is provided with a third guide groove for accommodating the second elastic member 35. One end of the second elastic member 35 is accommodated in the third guide groove (not shown in the figure), and the other end is sleeved on the outer periphery of the second limit member 34 and elastically abuts against the limit ring 341. When the knob 331 is retracted into the shell 1, the second elastic member 35 applies a rebound force toward the push rod 333 to the second limit ring 341, and at the same time, the limit ring 341 abuts against the end wall of the limit through hole 3325. These two forces are balanced to keep the second limit member 34 from axial displacement, so that the knob 331 does not produce axial displacement, so that the position of the button 33 is stable when it is received in the shell 1, and no shaking occurs. In actual applications, the position of the limiting ring 341 on the second limiting member 34 and the elastic force of the second elastic member 35 can be adjusted so that when the button 33 is received in the shell 1, the end face of the cap body 334 exposed in the shell 1 is flush with the outer surface of the shell 1, thereby making the appearance of the device smoother and more complete, and easier for the user to hold.

[0058] The content of the present invention is further explained below through the installation and operation process of the adjustment component 3.

[0059] The installation process of the adjustment component 3 may specifically be:

[0060] First, the push rod 333 and the pressure rod 332 are sequentially installed into the sleeve 311 from the opening of the installation groove 3111, and one end of the push rod 333 extends out of the sleeve 311 from the avoidance hole 3114. At the same time, the first convex strips 3322 are respectively accommodated in the corresponding first guide grooves 3116. The second convex strips 3331 are respectively accommodated in the corresponding first guide grooves 3116 and second guide grooves 3118, and the ends of each second convex strip 3331 are respectively abutted against the end surface of the avoidance hole 3114. Then, the connecting column 3341 on the cap body 334 is tightly inserted into the connecting hole, and the second stopper 34 is installed into the sleeve 311 from the open end of the installation groove 3111, and one end of the second stopper 34 passes through the pressure rod 332 and the push rod 333 in sequence and is tightly inserted into the connecting column 3341. Then, the second elastic member 35 and the first elastic member 32 are respectively placed in the pressure rod 332, wherein the second elastic member 35 is sleeved on the second limiting member 34. The other ends of the two springs are respectively installed on the mounting columns 3123, and then the cover plate 3121 covers the opening of the mounting groove 3111, the side plate 3122 is sleeved on the outer periphery of the sleeve 311, and the limiting strip 3119 extends into the limiting slot. The damping member 6 is installed in the second annular limiting groove 3113. Finally, the assembled adjustment component 3 is placed into the mounting hole 121 by one end of the screw rod until the other end of the screw rod passes through the threaded hole and is mounted on the slide groove 123, and then the limiting rib 124 is inserted from the outside of the mounting bracket 12 into the arc hole 122 and extends into the mounting hole 121, and is partially inserted into the first annular limiting groove 3112.

[0061] The working process of the regulating component 3 may specifically be:

[0062] The state where the button 33 extends out of the housing 1 is taken as the initial state. When the cap body 334 is pressed, the cap body 334 drives the push rod 333 to slide toward the first elastic member 32, and the plurality of second convex strips 3331 slide along the corresponding guide grooves. The pressure rod 332 compresses the first elastic member 32 under the push of the push rod 333. The plurality of first convex strips 3322 first slide along the corresponding first guide groove 3116. When sliding to the end of the first guide groove 3116 close to the first elastic member 32, the pressure rod 332 rotates relative to the push rod 333 and the convex block 3115 under the action of the first arc guide surface 3323 and the second arc guide surface 3332. At the same time, each first convex strip 3322 slides out of the first guide groove 3116 and slides along the corresponding lower surface 3117a to the junction of the lower surface 3117a and the height surface 3117b under the action of the third arc guide surface. When the pressure applied to the cap body 334 is removed, the pressure rod 332 abuts against the joint under the action of the rebound force of the first elastic member 32, thereby engaging with the engaging portion 3117 to keep the cap body 334 accommodated in the housing 1. In this process, the second stopper 34 also slides toward the second elastic member 35 driven by the cap body 334, and compresses the second elastic member 35. When the pressure is removed, the second stopper 34 is subjected to the rebound force of the second elastic member 35 toward the cap body 334, and the stopper ring 341 abuts against the end face of the stopper through hole 3325 under the action of the rebound force, so that the second stopper 34 and the knob 331 remain in a clamped state, so that when the button 33 is retracted into the housing 1, the knob 331 will not generate axial displacement.

[0063] When the button 33 is stored in the housing 1, the cap body 334 is continuously pressed, and the cap body 334 drives the push rod 333 to slide toward the first elastic member 32, and the plurality of second convex strips 3331 slide along the corresponding guide grooves. The pressure rod 332 further compresses the first elastic member 32 under the push of the push rod 333, and the plurality of first convex strips 3322 slide along the axial direction until they slide out of the joint. Under the action of the first arc-shaped guide surface 3323 and the second arc-shaped guide surface 3332, the pressure rod 332 rotates relative to the push rod 333 and the convex block 3115, and at the same time, each first convex strip 3322 slides out of the corresponding engaging portion 3117, and under the action of the third arc-shaped guide surface, slides along the corresponding higher surface 3117c to the adjacent first guide groove 3116. At this time, the pressure applied to the cap body 334 is released, and the pressure rod 332 slides toward the knob 331 under the action of the rebound force of the first elastic member 32, and each second ridge 3331 slides along the corresponding first guide groove 3116, and pushes the push rod 333 to slide in the direction away from the first elastic member 32 until the end of each first ridge 3322 abuts against the end face of the avoidance hole 3114, so as to keep the cap body 334 extending out of the shell 1.

[0064] When the part of the cap body 334 extending out of the housing 1 is rotated under force, the cap body 334 drives the push rod 333 to rotate. Since the push rod 333 is now firmly held on the sleeve 311, the sleeve 311 rotates in the mounting hole 121 driven by the push rod 333 and drives the screw rod. The screw rod cooperates with the threaded hole to make the sliding member 2 slide along the axial direction of the screw rod, thereby adjusting the size of the air inlet 111 to achieve the purpose of adjusting the air intake. The air intake is adjusted by rotating the button, which is convenient for the user to operate and control the adjustment amount.

[0065] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
