Description

An aerosol generator Technical Field

[0001] This utility model relates to the field of aerosol generators. Background Technology

[0002] To meet users' personalized needs for aerosol concentration, existing aerosol generators use adjustable components to regulate the size of the air inlet, thereby adjusting the air intake volume. However, in existing technologies, operating components are usually installed on the device surface for user operation. Because these operating components protrude from the device's exterior surface, they not only affect the integrity of the device's appearance but also easily cause false triggering and misoperation, causing inconvenience to users.

[0003] Therefore, existing technologies still need to be improved and enhanced. Summary of the Invention

[0004] The main purpose of this invention is to provide an aerosol generator that can accurately regulate gas flow while concealing buttons to prevent accidental triggering.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An aerosol generator includes a housing with an air inlet, a sliding member with a first transmission part, and an adjustment assembly. The sliding member is slidably mounted on the housing corresponding to the air inlet. One end of the adjustment assembly is provided with a second transmission part adapted to the first transmission part, and the other end is provided with a retractable button. The adjustment assembly is rotatably mounted on the housing, and the second transmission part is adapted to and connected to the first transmission part. When the button extending out of the housing is rotated, it drives the second transmission part to rotate and engage with the first transmission part, so that the sliding member slides within the housing and at least partially closes the air inlet.

[0007] The aerosol generator, wherein the adjustment component includes a housing with a movable cavity, a first elastic element housed within the movable cavity, and a button. One end of the housing has a second transmission part protruding from it, and the button is movably mounted on the other end of the housing. One end of the button is housed within the movable cavity and elastically abuts against the first elastic element, while the other end extends out of the movable cavity and is exposed in the housing. By pressing the exposed end of the button, the button can be extended or retracted into the housing.

[0008] The aerosol generator includes a button comprising a knob and a pressure rod with a first limiting member. The pressure rod is housed within the movable cavity and one end elastically abuts against the first elastic member. One end of the knob is slidably mounted within the movable cavity and clamped between the pressure rod and the wall of the movable cavity. The other end of the knob passes through the movable cavity and extends out of the housing. When the portion of the knob extending out of the housing is pressed, the knob slides toward the pressure rod and presses against it. The pressure rod slides and rotates simultaneously under the action of the knob and the first elastic member until the first limiting member engages with the locking portion provided on the wall of the movable cavity, at which point the portion of the knob extending out of the housing retracts into the housing.

[0009] In the aerosol generator, the pressure rod has a first arc-shaped guide surface on the side facing the knob, and the knob has a second arc-shaped guide surface on the side facing the pressure rod. When the knob presses against the pressure rod, the pressure rod compresses the first elastic element, and the first arc-shaped guide surface slides along the second arc-shaped guide surface, so that the pressure rod rotates relative to the knob.

[0010] The aerosol generator, wherein the pressure rod includes a pressure rod body, the pressure rod body is provided with a receiving groove along the axial direction for accommodating the first elastic member, and a plurality of first protrusions are provided at intervals on the outer periphery of the pressure rod body, the plurality of first protrusions being centrally symmetrically distributed to form the first limiting member.

[0011] The aerosol generator has a plurality of protrusions extending along the axial direction of the sleeve on the wall of the movable cavity. Each protrusion is symmetrically distributed around the central axis of the sleeve, and adjacent protrusions form a first guide groove adapted to the first protrusion. Each protrusion has a locking part at the end away from the button. Each first protrusion is slidably accommodated in the corresponding first guide groove. When the part of the knob that extends out of the housing is pressed, the knob drives the pressure rod to compress the first elastic element. Each first protrusion slides in the corresponding first guide groove until it slides out of the first guide groove and rotates relative to the pressure rod to engage with the corresponding locking part. The knob then retracts into the housing.

[0012] In the aerosol generator, the end of the protrusion away from the button is provided with a third arc-shaped guide surface, which extends to the corresponding engaging part. When each first protrusion slides out of the corresponding first guide groove, each first protrusion rotates along the corresponding third arc-shaped guide surface to the engaging part.

[0013] The aerosol generator includes a knob comprising a push rod and a cap. One end of the push rod is fixedly connected to the cap, and the other end extends into the movable cavity and is provided with several second protrusions symmetrically distributed around the circumference of the push rod. The cavity wall of the movable cavity is provided with several second guide grooves that are adapted to the second protrusions. When the knob retracts into the housing, pressing the knob until the pressure rod is pushed by the push rod to slide out of the engaging part, the pressure rod, under the restoring force of the first elastic element, drives the push rod to slide away from the first elastic element until the ends of each second protrusion abut against the cavity wall of the movable cavity, so that the cap extends out of the housing.

[0014] The aerosol generator includes a housing comprising a sleeve with a mounting groove and a cover. One end of the cover covers the opening of the mounting groove, and the other end protrudes from the sleeve with a second transmission part. The housing is provided with a mounting hole adapted to the sleeve, and the sleeve is rotatably accommodated in the mounting hole.

[0015] The aerosol generator has a limiting rib extending radially from one of the mounting hole wall and the outer periphery of the sleeve, and the other has a first annular limiting groove adapted to the guiding rib. When the sleeve is housed in the mounting hole, the limiting rib is housed in the first annular limiting groove and can rotate along the first annular limiting groove.

[0016] The aerosol generator, wherein the adjustment component further includes a second limiting member with a limiting ring, the pressure rod has a coaxial limiting through hole, one end of the second limiting member is coaxially inserted into the end of the knob facing the pressure rod, and the other end passes through the limiting through hole and slidably extends into the pressure rod, the limiting ring is housed in the pressure rod, and when the knob retracts into the housing, the limiting ring abuts against the end face of the limiting hole.

[0017] The aerosol generator further includes a second elastic element, one end of which elastically abuts against the wall of the movable cavity, and the other end of which elastically abuts against one end of the second limiting element that extends into the pressure rod.

[0018] In the aerosol generator, the first transmission part is a threaded hole passing through the sliding member, and the second transmission part is a lead screw adapted to the threaded hole. One end of the lead screw is connected to the adjustment component, and the other end passes through the threaded hole and is mounted on the housing. When the button is turned, the lead screw is driven to rotate, so that the threaded hole engages with the lead screw for transmission, and drives the sliding member to slide.

[0019] The aerosol generator, wherein the housing includes an outer shell and a support, the outer shell is provided with the air inlet, the support is provided with a sliding groove, the opening of the sliding groove faces the air inlet and is connected to the air inlet, the sliding member is slidably installed in the sliding groove and fits against the inner wall of the outer shell where the air inlet is provided, when the sliding member slides relative to the air inlet under the action of the first transmission part, the sliding member at least partially closes the air inlet.

[0020] Beneficial Effects: This utility model provides an aerosol generator, including a housing, a sliding member, and an adjusting assembly. The housing has an air inlet, and the sliding member is slidably mounted on the housing corresponding to the air inlet. One end of the adjusting assembly has a second transmission part adapted to the first transmission part, and the other end has a retractable button. The adjusting assembly is rotatably mounted on the housing, and the second transmission part is adapted to and connected to the first transmission part. When the button extending from the housing is rotated, the button drives the second transmission part to rotate and engage with the first transmission part, so that the sliding member slides within the housing and at least partially closes the air inlet. This embodiment achieves precise air adjustment by rotating the retractable button to realize the transmission engagement between the sliding member and the adjusting assembly. Simultaneously, the retractable adjusting button facilitates user storage and prevents accidental button activation. Attached Figure Description

If the specific posture changes, the directional indicator will also change accordingly.

[0038] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] This utility model proposes an aerosol generator, as shown in Figures 1-10. The aerosol generator includes a housing 1, a sliding member 2, and an adjusting assembly 3. The housing 1 has an air inlet 111, and the sliding member 2 is slidably mounted on the housing 1 corresponding to the air inlet 111. One end of the adjusting assembly 3 has a second transmission part 5 adapted to the first transmission part 4, and the other end has a retractable button 33. The adjusting assembly 3 is rotatably mounted on the housing 1, and the second transmission part 5 is adapted to and connected to the first transmission part 4. When the button 33 extending from the housing 1 is rotated, the button 33 drives the second transmission part 5 to rotate and engage with the first transmission part 4, so that the sliding member 2 slides within the housing 1 and at least partially closes the air inlet 111. In this embodiment, the retractable button 33 is rotated to achieve the transmission engagement between the sliding member 2 and the adjusting assembly 3, thereby achieving precise air adjustment. At the same time, the retractable adjusting button 33 is convenient for users to store, and can also prevent the button 33 from being accidentally triggered.

[0041] In some embodiments, as shown in Figures 3 and 8, the housing 1 includes an outer shell 11 and a bracket 12. The outer shell 11 has a hollow structure, and the side wall of the outer shell 11 is provided with the air inlet 111. The bracket 12 is installed inside the outer shell 11, and the bracket 12 is provided with a groove 123 for installing the slider 2 and a mounting hole 121 for installing the adjustment assembly 3. The outer shell 11 is provided with a through hole 112 corresponding to the mounting hole 121. When the bracket 12 is installed inside the outer shell 11, the mounting hole 121 is exposed from the through hole 112, and the button 33 extends out of the outer shell 11 through the mounting hole 121 and the through hole 112 in sequence. The opening direction of the 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 housed in the slide groove 123, the outer periphery of the sliding member 2 fits against the inner wall of the slide groove 123, thereby limiting the sliding member 2 through the inner wall of the slide groove 123. Preferably, the side of the sliding member 2 exposed from the opening of the slide groove 123 fits against the inner wall of the outer casing 11. When the sliding member 2 slides in the slide groove 123, it slides against the inner wall of the outer casing 11, thereby reducing the airflow from the gap between the sliding member 2 and the outer casing 11 when the sliding member 2 closes the air inlet 111. In practical applications, a sealing element can also be provided on the side of the sliding member 2 facing the inner wall of the outer casing 11, or a sealing element can be provided around the air outlet on the inner wall of the outer casing 11. The sealing element reduces the gap between the sliding member 2 and the outer casing 11, and also increases the sliding resistance between the sliding member 2 and the outer casing 11, enhancing the user's adjustment feel.

[0042] In some embodiments, referring to Figures 3 and 4, the adjustment component 3 includes a housing 31, a first elastic element 32, and a button 33. The housing 31 is rotatably mounted within the mounting hole 121. The housing 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 under the drive of the button 33, the sleeve 311 rotates within the mounting hole 121 about its central axis. Since the sleeve 311 is adapted to the mounting hole 121, the outer periphery of the sleeve 311 fits against the inner wall of the mounting hole 121, thereby limiting the sleeve 311 through the inner wall of the mounting hole 121. Preferably, the wall of the mounting hole 121 has 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 the axial displacement of the sleeve 311 can also be restricted, preventing the sleeve 311 from dislodging from the mounting hole 121. Preferably, the limiting rib 124 is detachably connected to the bracket 12, that is, the wall of the mounting hole 121 is provided with an arc-shaped hole 122 adapted to the limiting rib 124. The limiting rib 124 is inserted into the arc-shaped hole 122 from the outside of the bracket 12 and protrudes into the mounting hole 121, finally partially inserting into the first annular limiting groove 3112. In practical applications, there can be one, two, or more limiting ribs 124. The number of the first annular limiting grooves 3112 corresponds to the number of limiting ribs 124. Of course, the limiting ribs 124 can also be provided on the sleeve 311, and the first annular limiting grooves 3112 are provided on the wall of the mounting hole 121.

[0043] In some embodiments, the adjustment assembly 3 may further include a damping element 6. The damping element 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 element 6 is annular, and the annular damping element 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 element 6. The damping element 6 is partially accommodated in the second annular limiting groove 3113, and partially protrudes out and elastically abuts against the wall of the mounting hole 121. The damping element 6 is made of a soft rubber material, such as silicone, rubber, or silicone rubber. The elastic abutment between the damping element 6 and the wall of the mounting hole 121 increases the friction between the sleeve 311 and the wall of the mounting hole 121.

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

[0045] Specifically, the lead screw protrudes into the slide groove 123 through one side wall and fits into the threaded hole, then passes through the other side wall of the slide groove 123, thus being mounted within the slide groove 123. Correspondingly, the opposite side walls of the slide groove 123 are each provided with a rotating hole. The lead screw passes through the two rotating holes in sequence and can rotate relative to the slide groove 123. When the button 33 is turned, the lead screw rotates under the drive of the sleeve 311 and engages with the threaded hole, thereby driving the sliding member 2 to move along the axial direction of the lead screw. This allows the sliding member 2 to slide relative to the air inlet 111 within the slide groove 123. As the lead screw rotates, the sliding member 2 gradually closes the air inlet 111, causing the air inlet 111 to gradually decrease in size and the air intake to decrease accordingly. Conversely, when the lead screw rotates in the opposite direction, the sliding member 2 gradually opens the air inlet 111, causing the air inlet 111 to gradually enlarge and the air intake to increase accordingly. In this embodiment, the sliding adjustment of the sliding component 2 is achieved through the transmission cooperation between the lead screw and the threaded hole, which facilitates the control of the air volume and achieves precise air adjustment.

[0046] It is worth noting that the first transmission unit 4 and the second transmission unit 5 are not limited to the above-described structure, and can also be other transmission methods. For example, the first transmission unit 4 uses a rack and pinion, and correspondingly, the second transmission unit 5 uses a matching gear. When the gear rotates, the rack meshes with the size and slides within the slide groove 123, thereby adjusting the size of the air intake 111. Smooth adjustment is achieved through gear transmission.

[0047] In some embodiments, as shown in Figures 5 and 8, the cover 312 includes a cover plate 3121 and a side plate 3122. 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 its shape and size are adapted to the outer periphery of the sleeve 311. Since the sleeve 311 rotates with the button 33, the sleeve 311 has a cylindrical structure, and correspondingly, the side plate 3122 forms a matching ring. The side plate 3122 is fastened to the outer periphery of the sleeve 311 to fasten the cover 312 to the sleeve 311. Preferably, the side plate 3122 is provided with a limiting slot (not shown in the figure) extending in the axial direction, and the outer periphery of the sleeve 311 has a limiting strip 3119 extending in the axial direction. When the cover 312 covers the sleeve 311, the limiting strip 3119 is inserted into the limiting slot. The engagement between the limiting strip 3119 and the limiting slot not only limits the position of the cover 312 but also prevents radial displacement between the sleeve 311 and the cover 312, thus preventing stripping. Alternatively, the protruding strip can also be located on the side plate 3122, and the limiting slot can also be located on the sleeve 311. In practical applications, other limiting structures can also be provided, such as a threaded engagement structure opposite to the direction of rotation.

[0048] In some embodiments, the second transmission part 5 is perpendicularly connected to the cover plate 3121 and protrudes into the mounting groove 3111. A mounting post 3123 protrudes from the side of the cover plate 3121 opposite to the second transmission part 5. The first elastic member 32 is a spring adapted to the mounting post 3123. One end of the first elastic member 32 is securely sleeved onto the mounting post 3123, and the other end elastically abuts against the button 33. The mounting post 3123 fixes and limits the first elastic member 32.

[0049] In some embodiments, as shown in Figures 4-8, the button 33 includes a knob 331 and a lever 332. The knob 331 includes a push rod 333 and a cap 334. One end of the push rod 333 is fixedly connected to the cap 334. In practical applications, the cap 334 has a round cap structure coaxial with the push rod 333, and a connecting post 3341 protrudes from it toward the push rod 333. The push rod 333 is provided with a connecting hole (not shown in the figure) that matches the connecting post 3341. The connecting post 3341 is tightly inserted into the connecting hole to fasten the cap 334 to the push rod 333. The other end of the push rod 333 extends into the movable cavity 313 and can slide within the movable cavity 313. Correspondingly, the end of the sleeve 311 away from the cover 312 (i.e., the bottom wall of the mounting groove 3111) is provided with a clearance hole 3114 for the push rod 333 to pass through. The top rod 333, housed within the sleeve 311, has a plurality of second protrusions 3331 spaced circumferentially at one end. The length of each second protrusion 3331 extends along the axial direction of the top rod 333. The plurality of second protrusions 3331 are centrally symmetrically distributed about the central axis of the top rod 333. The plurality of second protrusions 3331 surround the top rod 333 to form an annular structure. The outer diameter of this annular structure is larger than the diameter of the clearance hole 3114. The annular structure formed by the second protrusions 3331 abuts against the end face of the clearance hole 3114 to limit the movement of the knob 331, preventing the knob 331 from being ejected from the movable cavity 313 under the action of the first elastic member 32.

[0050] Correspondingly, the inner wall of the sleeve 311, i.e., the cavity wall of the movable cavity 313, is provided with a plurality of second guide grooves 3118 adapted to the second protrusion 3331. The second protrusion 3331 is respectively housed in the corresponding second guide groove 3118. When the cap 334 is pressed, the cap 334 pushes the push rod 333 to slide toward the pressure rod 332. Under the action of the second protrusion 3331, the push rod 333 slides along the second guide groove 3118. Through the cooperation of the second protrusion 3331 and the second guide groove 3118, the push rod 333 is guided and limited, preventing the push rod 333 from sliding off course or rotating.

[0051] The pressure rod 332 includes a pressure rod body 3321, which has a rotating structure and is coaxially mounted inside the sleeve 311. One side of the pressure rod body 3321 facing the mounting post 3123 has a receiving groove 3324 adapted to the first elastic member 32. The end of the first elastic member 32 away from the mounting post 3123 is housed 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-compressed state. The outer periphery of the pressure rod body 3321 is provided with a plurality of first protrusions 3322, each extending along the axial direction of the pressure rod body 3321. The plurality of first protrusions 3322 are centrally symmetrically distributed about the central axis of the pressure rod body 3321 to form a first limiting member.

[0052] In some embodiments, the pressure rod 332 has a first arc-shaped guide surface 3323 on the side facing the top rod 333, and the top rod 333 has a second arc-shaped guide surface 3332 on the side 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 top rod 333, driven by the cap 334, pushes the pressure rod 332 towards the first elastic member 32, the pressure rod 332 slides towards and compresses the first elastic member 32, while simultaneously being 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 rotates relative to the top rod 333 due to radial displacement. Preferably, each of the first protrusions 3322 has a first arc-shaped guide surface 3323 at one end facing the top rod 333, and each of the second protrusions 3331 has a second arc-shaped guide surface 3332 at one end facing the pressure rod 332. When the top rod 333 is pressed and slides, the second protrusions 3331 support the pressure rod 332, and under the combined action of the cooperation of the second arc-shaped guide surface 3332 and the first arc-shaped guide surface 3323 and the rebound force of the first elastic element 32, the pressure rod 332 slides along the axial direction of the sleeve 311 while rotating.

[0053] In some embodiments, the inner wall of the sleeve 311, i.e., the cavity wall of the movable 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 circumferentially around the sleeve 311 and are centrally symmetrical about the central axis of the sleeve 311. The space between two adjacent protrusions 3115 forms a first guide groove 3116 adapted to the first protrusion 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 adjacent protrusions 3115 form the side walls of the first guide groove 3116. The number of the first guide grooves 3116 corresponds to the number of the first protrusions 3322. Since the number of protrusions 3115 is the same as the number of first guide grooves 3116, the number of protrusions 3115 is also the same as the number of first protrusions 3322. For example, if there are four first protrusions 3322 and the included angle between adjacent protrusions is 45 degrees, then there are also four protrusions 3115. 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 of the first protrusions 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 disposed on the protrusion 3115. That is, the protrusion 3115 is provided with a second guide groove 3118 adapted to the second protrusion 3331 along the axial direction, so as to make full use of the space of the inner wall of the sleeve 311. Furthermore, the groove width of the first guide groove 3116 is also compatible with the second protrusion 3331, so that the second protrusion 3331 can be accommodated in the first guide groove 3116. In other words, both the first guide groove 3116 and the second guide groove 3118 can be used to form a groove for the second protrusion 3331 to slide. This can increase the number of second protrusions 3331, 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, making the push rod 333 push the pressure rod 332 more smoothly and the pressure rod 332 more evenly stressed.

[0055] Furthermore, as shown in Figure 5, the end of the protrusion 3115 away from the button 33 is provided with a locking portion 3117. The locking portion 3117 is stepped, including a lower surface 3117a, a higher surface 3117b, and a higher surface 3117c, which are connected in sequence to form a Z-shaped step. The lower surface 3117a and the higher surface 3117c both face the direction of the first elastic member 32. When the pressure rod 332 is under the combined action of the top rod 333 and the first elastic member 32, the first protrusion 3322 slides out from 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 removed. Under the action of the rebound force of the first elastic member 32, each of the first protrusions 3322 abuts against the junction of the lower surface 3117a and the height surface 3117b of the corresponding engaging part 3117 and remains locked. At this time, the cap body 334 retracts into the housing 1 and the button 33 is stored. When the cap body 334 is pressed, the pressure rod 332, under the combined action of the top rod 333 and the first elastic member 32, first moves toward the first elastic member 32 and rotates. At this time, each of the first protrusions 3322 disengages from the corresponding engaging part 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 released, and the pressure rod 332 slides toward the top rod 333 under the rebound force of the first elastic member 32. Each of the first protrusions 3322 slides along the first guide groove 3116 and pushes the top rod 333 toward the end of the sleeve 311 away from the cover body 312 until the second protrusion 3331 on the top rod 333 abuts against the end face of the clearance hole 3114 and remains locked. At this time, the cap body 334 extends out of the housing 1, and the button 33 protrudes out for user operation. In this way, the user can eject the button from the housing when adjusting the air intake and retract it when not in use. This not only maintains the integrity of the device and makes it easier for the user to hold, but also prevents accidental operation of the protruding button. Furthermore, by designing the knob to extend and retract within the movable cavity of the housing, and by using locking parts and clearance holes in the housing to lock the knob's extended or retracted state, the knob, when locked in the housing, can drive the entire housing to rotate within the mounting hole, thereby achieving the purpose of air adjustment. In other words, in this embodiment, the extension and retraction of the button and the rotation of the adjustment component are independent of each other and do not interfere with each other, making it convenient for the user to operate.

[0056] Preferably, referring to Figures 4 and 10, the adjusting assembly 3 further includes a second limiting member 34 with a limiting ring 341. The second limiting member 34 is rod-shaped. One end of the second limiting member 34 is securely inserted into the knob 331 and is coaxial with the knob 331. The pressure rod 332 has a limiting through hole 3325 coaxial with the second limiting member 34, and the diameter 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 slidably extends into the pressure rod 332, and is accommodated in the receiving 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 diameter of the limiting through hole 3325. When the knob 331 is retracted into the housing 1, the limiting ring 341 abuts against the end face of the limiting through hole 3325. A pulling force is applied to the knob 331 by the limiting ring 341 toward the pressure rod 332, so that when the pressure rod 332 abuts against the engaging part 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 element 35. The mounting post 3123 is provided with a third guide groove for accommodating the second elastic element 35. One end of the second elastic element 35 is housed in the third guide groove (not shown in the figure), and the other end is sleeved on the outer periphery of the second limiting member 34 and elastically abuts against the limiting ring 341. When the knob 331 retracts into the housing 1, the second elastic element 35 applies a rebound force toward the top rod 333 to the second limiting ring 341, while the limiting ring 341 abuts against the end wall of the limiting through hole 3325. These two forces balance each other to keep the second limiting member 34 from axial displacement, so that the knob 331 does not axially displace, thereby making the button 33 stable in position when it is stored in the housing 1 and preventing it from shaking. In practical 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 stored in the housing 1, the cap 334 is exposed on the end face of the housing 1 and flush with the outer surface of the housing 1, making the appearance of the device smoother and more complete, and easier for the user to hold.

[0058] The following explanation of the invention will further illustrate the content of this utility model by adjusting the installation and operation process of component 3.

[0059] The installation process of the adjustment component 3 can be specifically as follows:

[0060] First, insert the top rod 333 and the pressure rod 332 into the sleeve 311 through the opening of the mounting groove 3111, with one end of the top rod 333 extending out of the sleeve 3114 from the clearance hole 3114. Simultaneously, the first protrusions 3322 are respectively housed in the corresponding first guide grooves 3116. The second protrusions 3331 are respectively housed in the corresponding first guide grooves 3116 and second guide grooves 3118, with the ends of each second protrusion 3331 abutting against the end face of the clearance hole 3114. Then, the connecting post 3341 on the cap 334 is securely inserted into the connecting hole, and the second limiting member 34 is inserted into the sleeve 311 through the opening end of the mounting groove 3111, with one end of the second limiting member 34 passing sequentially through the pressure rod 332 and the top rod 333 and securely inserted into the connecting post 3341. Next, the second elastic element 35 and the first elastic element 32 are respectively placed into the pressure rod 332, wherein the second elastic element 35 is sleeved on the second limiting element 34. The other ends of the two springs are respectively installed on the mounting post 3123, and then the cover plate 3121 is used to cover 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 groove. The damping element 6 is installed in the second annular limiting groove 3113. Finally, the assembled adjusting component 3 is inserted into the mounting hole 121 from one end of the lead screw until the other end of the lead screw passes through the threaded hole and is mounted on the sliding groove 123. Then, the limiting rib 124 is inserted into the arc-shaped hole 122 from the outside of the mounting bracket 12 and extends into the mounting hole 121, and is partially inserted into the first annular limiting groove 3112.

[0061] The specific working process of the adjustment component 3 can be as follows:

[0062] Taking the state of button 33 extending out of housing 1 as the initial state, when cap 334 is pressed, cap 334 drives top rod 333 to slide toward first elastic member 32, and several second protrusions 3331 slide along corresponding guide grooves. The pressure rod 332 compresses the first elastic member 32 under the push of top rod 333, and several first protrusions 3322 first slide along corresponding first guide grooves 3116. When sliding to the end of first guide groove 3116 near the first elastic member 32, under the action of first arc-shaped guide surface 3323 and second arc-shaped guide surface 3332, the pressure rod 332 rotates relative to top rod 333 and protrusion 3115. At the same time, each first protrusion 3322 slides out of first guide groove 3116 and, under the action of third arc-shaped guide surface, slides along corresponding lower surface 3117a to the junction of lower surface 3117a and height surface 3117b. When the pressure applied to the cap 334 is removed, the pressure rod 332, under the rebound force of the first elastic member 32, abuts against the joint, thereby engaging with the engaging part 3117 to keep the cap 334 housed within the housing 1. During this process, the second limiting member 34 also slides towards the second elastic member 35 under the action of the cap 334, compressing the second elastic member 35. When the pressure is removed, the second limiting member 34 is subjected to the rebound force of the second elastic member 35 towards the cap 334, and the limiting ring 341 abuts against the end face of the limiting through hole 3325 under the action of the rebound force, so that the second limiting member 34 and the knob 331 remain locked, so that the knob 331 will not have axial displacement when the button 33 retracts into the housing 1.

[0063] When button 33 is retracted into housing 1, pressing cap 334 continues, causing cap 334 to slide push rod 333 toward the first elastic member 32, and several second protrusions 3331 slide along their corresponding guide grooves. Pushed by push rod 333, pressure rod 332 further compresses the first elastic member 32. When several first protrusions 3322 slide axially 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, pressure rod 332 rotates relative to push rod 333 and protrusion 3115. Simultaneously, each first protrusion 3322 slides out of its corresponding engaging portion 3117 and, under the action of the third arc-shaped guide surface, slides along its corresponding higher surface 3117c into the adjacent first guide groove 3116. At this time, the pressure applied to the cap body 334 is removed. Under the action of the rebound force of the first elastic member 32, the pressure rod 332 slides toward the knob 331. Each second protrusion 3331 slides along the corresponding first guide groove 3116 and pushes the top rod 333 to slide away from the first elastic member 32 until the end of each first protrusion 3322 abuts against the end face of the relief hole 3114 to keep the cap body 334 protruding from the shell 1.

[0064] When the portion of the cap 334 extending out of the housing 1 is rotated under force, the cap 334 drives the top rod 333 to rotate. Since the top rod 333 is now firmly held against the sleeve 311, the sleeve 311 rotates within the mounting hole 121 under the drive of the top rod 333, and drives the lead screw. The lead screw engages with the threaded hole, allowing the sliding member 2 to slide along the axial direction of the lead screw, thereby adjusting the size of the air inlet 111 and achieving the purpose of adjusting the air intake. The air intake is adjusted by rotating the button, which is convenient for users to operate and control the adjustment amount.

[0065] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
