Description

Technical Field

[0001] This invention relates to the field of hair dryer technology, specifically to a styling accessory and hair dryer system. Background Technology

[0002] Hair dryers are common household appliances that work by converting electrical energy into heat and mechanical energy (wind power). To meet various styling needs, existing hair dryer systems, in addition to the hair dryer itself, also include one or more styling accessories. These accessories assist the hair dryer, providing functions such as hair styling, scalp care, and scalp massage. They can include, but are not limited to, various hair combs, concentrator nozzles, diffuser nozzles, oil dispensers, and infrared emitters.

[0003] During use, the styling accessory connects to the air outlet of the hair dryer, guiding the airflow from the hair dryer's outlet to the target location on the styling accessory. Different styling accessories, or even the same accessory for different effects, require varying airflow. Existing hair dryers only offer one or two airflow settings, which cannot adapt to meet the different airflow needs of styling accessories. Summary of the Invention

[0004] The main objective of this invention is to propose a styling accessory and hair dryer system, which aims to solve the problem that the airflow adjustment of traditional hair dryers cannot adapt to meet the different airflow requirements of styling accessories.

[0005] To achieve the above objectives, the present invention provides a styling accessory adapted to a hair dryer, the styling accessory comprising:

[0006] The main housing has a channel, the channel having a first air outlet and a second air outlet, the first air outlet being detachably connected to the air outlet of the blower;

[0007] The structural design is located on the main housing and adjacent to the second air vent; and,

[0008] An adjustment assembly includes a cylindrical shell and an adjustment member. The cylindrical shell is connected to the main housing and communicates with the channel inside the cylindrical shell. The adjustment member is disposed inside the cylindrical shell and defines a ventilation gap together with the inner wall of the cylindrical shell.

[0009] The inner diameter of the cylindrical shell and / or the outer diameter of the adjusting member are gradually varied along the axial direction of the cylindrical shell, and the cylindrical shell and / or the adjusting member have an adjusting stroke that moves relative to the main shell along the axial direction of the cylindrical shell, so that the ventilation cross-sectional area of ​​the ventilation gap can be adjusted during the adjusting stroke.

[0010] Optionally, the cylindrical shell is detachably connected to the main housing, and the cylindrical shell is housed within the channel.

[0011] Optionally, the cylindrical shell is fixed relative to the main housing, and the adjusting member is translatably movable along the axial direction of the cylindrical shell to perform the adjusting stroke.

[0012] Optionally, the cylindrical shell has a first opening near the air outlet and a second opening away from the air outlet;

[0013] The adjusting member includes a cone with a gradually changing outer diameter, and the cone has a narrow end and a wide end that are arranged opposite to each other, with the narrow end facing the first cylinder opening.

[0014] Optionally, the adjusting member is housed within the cylindrical shell and is at least partially movable outside the cylindrical shell through the first opening, so as to adjust the ventilation cross-sectional area of ​​the ventilation gap by adjusting the area of ​​the adjusting member blocking the first opening.

[0015] Optionally, the shell is a tapered shape with a gradually changing inner diameter, and the trend of the inner diameter of the shell is opposite to the trend of the outer diameter of the adjusting member in the axial direction.

[0016] Optionally, the cylindrical shell has a first opening near the air outlet and a second opening away from the air outlet;

[0017] The inner wall of the cylinder shell has a stop rib protruding radially near the second cylinder opening, and the stop rib has a guide hole extending through it along the axial direction of the cylinder shell.

[0018] The adjusting member further includes a guide protrusion that protrudes from the wide end toward the narrow end. The guide protrusion is movably inserted through the guide hole along the axial direction of the cylinder shell, and the outer diameter of the guide protrusion is not greater than the outer diameter of the wide end, so that the stop rib limits and stops the wide end during the movement of the adjusting member toward the second cylinder opening.

[0019] Optionally, the adjustment component further includes:

[0020] An operating element, exposed on the outer wall of the main housing, has a driving stroke that moves circumferentially or tangentially relative to the main housing along the cylindrical shell under external force; and,

[0021] A transmission element is connected between the operating element and the movable housing and / or the adjusting element to convert the drive stroke into the adjusting stroke.

[0022] Optionally, the shell is housed in the channel and includes an inner cylinder and an outer cylinder that are movably fitted together from the inside to the outside. The adjusting member is movably disposed in the inner cylinder and extends at least partially toward the outer cylinder to form a guide protrusion. The sidewall of the outer cylinder is provided with a first elongated hole in its radial direction. In the circumferential direction of the shell, the first elongated hole gradually extends obliquely toward one axial end of the shell.

[0023] The main shell has a second elongated hole extending radially therethrough, and the second elongated hole extends elongatedly along the circumference of the shell.

[0024] One end of the operating component is slidably connected to the second elongated hole, and the other end is connected to the outer cylinder.

[0025] One end of the transmission component is slidably connected to the first elongated hole, and the other end extends into the cylindrical shell and is connected to the guide protrusion.

[0026] Driven by an external force, the operating member moves along the second elongated hole and drives the transmission member to move along the first elongated hole through the outer cylinder, so as to convert the circumferential translation of the operating member along the cylinder shell into the axial translation of the adjusting member along the cylinder shell.

[0027] In addition, to achieve the above objectives, the present invention also provides a hair dryer system, including a hair dryer and the styling accessories described above.

[0028] In the technical solution provided by this invention, the airflow generated by the hair dryer enters the channel through the air outlet and the first air inlet, and is finally discharged outward through the second air inlet to the vicinity of the styling structure, thereby assisting the styling structure in caring for the user's scalp and / or hair. During this process, because the barrel and main housing remain connected, the hair dryer, main housing, styling structure, and adjustment components are connected as a whole, making it more convenient for the user to hold and use. Since the barrel and channel are connected, the airflow discharged through the air outlet must first pass through the adjustment components before flowing towards the styling structure. Driven by the adjustment stroke of the barrel and / or the adjustment components, the ventilation cross-sectional area of ​​the ventilation gap defined by the barrel and the adjustment components can be flexibly adjusted, thus allowing the airflow towards the styling structure to be further adjusted to meet the different airflow requirements of the styling structure. This design is characterized by its simple structure and easy operation. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0041] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0042] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are 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 with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0043] Please combine Figures 1 to 7 This invention provides a styling accessory and its application in a hair dryer system. It is understood that the styling accessory can be used as a standalone product in various suitable application scenarios. Alternatively, the styling accessory can be used as an accessory, combined with the hair dryer as a complementary product in suitable application scenarios.

[0044] Specifically, the hair dryer includes a main body and a fan, and may also include a temperature control module and a filter assembly, depending on actual needs. The main body has an air inlet, an air outlet, and an air duct connecting the inlet and outlet. The fan is located within the air duct and drives external airflow through the inlet into the duct, through the duct, and finally out through the outlet. The temperature control module can be, but is not limited to, heating elements such as heating resistance wires and / or cooling elements such as cooling coils. The temperature control module can also be located within the air duct and heats or cools the flowing air to ensure that the airflow discharged through the outlet meets the user's temperature requirements. The filter assembly is generally located at the air inlet and may include, but is not limited to, one or more filter units. Each filter unit may be, for example, a metal filter screen or filter cotton.

[0045] The styling accessories are detachably installed on the main body of the hair dryer, such as at the air outlet, to guide the airflow discharged from the air outlet to flow through the styling accessories.

[0046] Specifically, the styling components include a main housing 100, a styling structure 200, and an adjustment assembly 300. The main housing 100 is provided with a channel 110, which has a first air vent 111 and a second air vent 112. The first air vent 111 is detachably connected to the air outlet of the blower. The shaped structure 200 is provided in the main housing 100 and is located adjacent to the second air vent 112. The adjustment component 300 includes a cylindrical shell 310 and an adjustment member 320. The cylindrical shell 310 is connected to the main housing 100 and communicates with the channel 110. The adjustment member 320 is located inside the cylindrical shell 310 and defines a ventilation gap together with the inner wall of the cylindrical shell 310. The inner diameter of the cylindrical shell 310 and / or the outer diameter of the adjustment member 320 are gradually changed along the axial direction of the cylindrical shell 310. The cylindrical shell 310 and / or the adjustment member 320 have an adjustment stroke that moves relative to the main housing 100 along the axial direction of the cylindrical shell 310, so that the ventilation cross-sectional area of ​​the ventilation gap can be adjusted during the adjustment stroke.

[0047] In the technical solution provided by this invention, the airflow generated by the hair dryer enters the channel 110 through the air outlet and the first air inlet 111, and is finally discharged outward through the second air inlet 112 to the vicinity of the styling structure 200, thereby assisting the styling structure 200 in caring for the user's scalp and / or hair. During this process, since the barrel shell 310 and the main shell 100 remain connected, the hair dryer, main shell 100, styling structure 200, and adjustment component 300 are connected as a whole, making it more convenient for the user to hold and use. Because the barrel shell 310 is connected to the channel 110, the airflow discharged outward through the air outlet must first pass through the adjustment component 300 before flowing towards the styling structure 200. Driven by the adjustment stroke of the barrel shell 310 and / or the adjustment component 320, the ventilation cross-sectional area of ​​the ventilation gap defined by the barrel shell 310 and the adjustment component 320 can be flexibly adjusted, thus allowing the airflow towards the styling structure 200 to be further adjusted to meet the different airflow requirements of the styling structure 200, and featuring a simple structure and easy operation.

[0048] The specific type of the styling structure 200 is not limited, and can be, but is not limited to, straightening comb teeth, curling comb teeth, hair oil generator, scalp massager, etc. The specific form of the main housing 100 can be adaptively set to suit the specific type of the styling structure 200, for example... Figures 1 to 7 As shown, when the styling structure 200 is specifically manifested as a curling comb tooth integrated on the main housing 100, the main housing 100 is roughly columnar.

[0049] The main housing 100 may contain one or more channels 110, depending on actual needs. When multiple channels 110 are provided, each channel 110 may be configured to be independent and not interconnected; or at least two of the channels 110 may be interconnected. Each channel 110 may be configured as a straight cavity structure or as a cavity structure that undergoes at least one bending extension in at least a part of its length.

[0050] The first air vent 111 and the second air duct are spaced apart on the main housing 100. Specifically, the first air vent 111 and the second air vent 112 can be located at opposite ends of the main housing 100 in a certain dimensional direction. Alternatively, the first air vent 111 and the second air vent 112 can be located at any position in a certain dimensional direction of the main housing 100 as needed.

[0051] The first air vent 111 and / or the second air vent 112 may be equipped with a filter structure as described above, depending on actual needs. Furthermore, the shape and size of the first air vent 111 and / or the second air vent 112 may be the same, or they may be different depending on actual needs. For example... Figures 1 to 2 As shown, when the main housing 100 is generally cylindrical, and the styling structure 200 is specifically represented by curling comb teeth arranged at intervals along the circumference of the main housing 100, the first air vent 111 can be specifically located at one end of the main housing 100, and its shape and size are approximately adapted to the air outlet of the matching hair dryer, so as to facilitate the docking of the styling accessories and the hair dryer through the first air vent 111 and the air outlet. The second air vent 112 can be specifically located on the outer peripheral sidewall of the main housing 100, and multiple vents are arranged at intervals along the circumference of the main housing 100. Each second air vent 112 can be located adjacent to each curling comb tooth. The size and shape of each second air vent 112 can be set to be the same or at least partially different. For example, in the direction away from the first air vent 111, the ventilation cross-sectional area of ​​each second air vent 112 gradually decreases.

[0052] The adjustment component 300 is connected to the main housing 100. Specifically, at least a portion of the main housing 100 and at least some components of the adjustment component 300 can be integrally formed. Alternatively, the main housing 100 and at least some components of the adjustment component 300 can be separately formed and then detachably or non-detachably connected. When the main housing 100 and the adjustment component 300 are detachably connected as a whole, the styling accessory has a first state where the main housing 100 and the adjustment component 300 are connected, and a second state where the main housing 100 and the adjustment component 300 are separated. In the first state, the styling accessory does not have an airflow adjustment function, and the air discharged from the outlet is circulated to the styling structure 200 with the maximum ventilation volume. In the second state, the styling accessory has different airflow adjustment modes, and can circulate the air discharged from the outlet to the styling structure 200 with the maximum ventilation volume, the minimum ventilation volume, or any ventilation volume in between, according to actual needs.

[0053] The adjustment component 300 can be externally mounted on the main housing 100, for example, connected to the second air outlet of the main housing 100; or connected to the first air outlet of the main housing 100. Taking the external connection of the adjustment component 300 to the first air outlet as an example, specifically, the adjustment component 300 can be connected between the main housing 100 and the blower, and the cylindrical shell 310 connects the air outlet and the first air outlet 111.

[0054] Of course, the adjustment component 300 can also be built into the main housing 100, for example, at least the barrel 310 can be housed within the channel 110, to reduce the complexity of the connection operation when the styling accessory is connected to the hair dryer. Specifically, when the barrel 310 is housed within the channel 110, it can be located near the first air outlet 111, near the second air outlet 112, or between the first air outlet 111 and the second air outlet 112. Figures 1 to 7 Taking the structure shown as an example, the adjustment component 300 is mainly housed in the channel 110 near the first air outlet 111. On the one hand, this facilitates the disassembly and assembly of the adjustment component 300; on the other hand, it makes the overall center of gravity of the styling accessory closer to the entire hair dryer, making it easier for the user to hold.

[0055] In addition, the adjustment component 300 can also be partially housed in the channel 110 (e.g., fixed by plugging), with the remaining part extending outward from the channel 110 via the first air vent 111 and connected to the air outlet of the blower in an adaptive manner.

[0056] When the cylindrical shell 310 is housed within the channel 110, its external outline and dimensions can be adapted to the internal shape and dimensions of the channel 110 at its location, thereby improving the fit and assembly stability of the adjusting component 300 within the main housing 100. At this time, the cylindrical shell 310 is also approximately cylindrical, and its dimensions correspond to those of the main housing 100 at its location. Specifically, the axial direction of the cylindrical shell 310 corresponds to the axial direction of the main housing 100 at its location, the radial direction of the cylindrical shell 310 corresponds to the radial direction of the main housing 100 at its location, and the circumferential direction of the cylindrical shell 310 corresponds to the circumferential direction of the main housing 100 at its location.

[0057] The adjusting member 320 is disposed within the cylindrical shell 310, and the inner wall of the cylindrical shell 310 and the outer wall of the adjusting member 320 are at least partially spaced apart to define a ventilation gap between them. Specifically, when the adjusting member 320 is approximately suspended in the middle of the cylindrical shell 310, the entire circumference of the inner wall of the cylindrical shell 310 and the entire circumference of the outer wall of the adjusting member 320 are spaced apart, and the defined ventilation gap is approximately annular. The ventilation cross-sectional area of ​​the ventilation gap corresponds to the radial cross-sectional area of ​​the main shell 100 / cylinder shell 310. When the ventilation cross-sectional area of ​​the ventilation gap increases, the flow rate of the gas that can flow through it increases, resulting in an increase in the amount of air discharged outward from the second air outlet 112; conversely, when the ventilation cross-sectional area of ​​the ventilation gap decreases, the flow rate of the gas that can flow through it decreases, resulting in a decrease in the amount of air discharged outward from the second air outlet 112. Therefore, by adjusting the size of the ventilation cross-sectional area of ​​the ventilation gap, the air volume at the second air inlet 112 can be directly adjusted.

[0058] The inner diameter of the shell 310 and / or the outer diameter of the adjusting element 320 are gradually varied along the axial direction of the shell 310.

[0059] The variation can occur only in the inner diameter of the shell 310, only in the outer diameter of the adjusting member 320, or in both. When both the inner diameter of the shell 310 and the outer diameter of the adjusting member 320 change, their trends can be opposite. For example, near the air outlet, the inner diameter of the shell 310 gradually increases while the outer diameter of the adjusting member 320 gradually decreases. Conversely, when both the inner diameter of the shell 310 and the outer diameter of the adjusting member 320 change, their trends can be the same, but the magnitude of the change can differ. For example, near the air outlet, both the inner diameter of the shell 310 and the outer diameter of the adjusting member 320 gradually decrease, but the unit decrease in the inner diameter of the shell 310 is greater than the unit decrease in the outer diameter of the adjusting member 320.

[0060] The gradual change can be stepped. For example, the inner diameter of the shell 310 and / or the outer diameter of the adjusting member 320 can have a multi-step gradual change. Of course, the gradual change can also be stepless. For example, the inner diameter of the shell 310 and / or the outer diameter of the adjusting member 320 can have a continuous gradual change, specifically, at least a portion of the shell 310 is a conical cylinder and / or at least a portion of the adjusting member 320 is a cone 321.

[0061] Next, the cylindrical shell 310 and / or the adjusting member 320 are movable relative to the main shell 100 along the axis of the cylindrical shell 310, thus having an adjusting stroke. The adjusting stroke can be formed by the adjusting member 320 being fixed relative to the main shell 100, and the cylindrical shell 310 being able to reciprocate and translate relative to the main shell 100 along its own axial direction; or by the cylindrical shell 310 being fixed relative to the main shell 100, and the adjusting member 320 being able to reciprocate and translate relative to the main shell 100 along the axial direction of the cylindrical shell 310; or by both the cylindrical shell 310 and the adjusting member 320 being able to reciprocate and translate relative to the main shell 100 along the axial direction of the cylindrical shell 310. When both the cylindrical shell 310 and the adjusting member 320 are movable, they can move in opposite directions or in the same direction but at different speeds. Specifically, as follows... Figures 2 to 3 As shown, the cylindrical shell 310 can be fixed relative to the main shell 100, and the adjusting member 320 can be moved along the axial direction of the cylindrical shell 310 to adjust the stroke.

[0062] The cylindrical shell 310 has a first opening 310a near the air outlet and a second opening 310b away from the air outlet. When the cylindrical shell 310 is external to the main housing 100, the first opening 310a is directly connected to the air outlet, and the second opening 310b is directly connected to the first air vent 111. Alternatively, when the cylindrical shell 310 is internal to the channel 110 of the main housing 100, the first opening 310a is located adjacent to the first air vent 111, and the second opening 310b is located closer to the second air vent 112 than the first opening 310a.

[0063] Please combine Figures 2 to 7 The adjusting member 320 includes a cone 321 with a gradually changing outer diameter, and the cone 321 has a narrow end and a wide end that are arranged opposite to each other, with the narrow end facing the first cylinder opening 310a.

[0064] Based on this, in one specific embodiment, the adjusting member 320 can be housed within the channel 110, and at least partially movable into the cylinder shell 310 via the second opening 310b. It can be understood that when the adjusting member 320 continuously moves towards the first opening 310a, its blocking area on the second opening 310b gradually increases, thereby gradually reducing the airflow entering the channel 110 via the second opening 310b, thus reducing the airflow. Conversely, when the adjusting member 320 continuously moves away from the first opening 310a, its blocking area on the second opening 310b gradually decreases, thereby gradually increasing the airflow entering the channel 110 via the second opening 310b, thus increasing the airflow.

[0065] In another embodiment, the inner diameter of the shell 310 can be set to gradually decrease from the second opening 310b to the first opening 310a. The adjusting member 320 is housed inside the shell 310 and is at least partially movable outside the shell 310 via the first opening 310a, so that the ventilation cross-sectional area of ​​the ventilation gap can be adjusted by adjusting the area of ​​the adjusting member 320 blocking the first opening 310a. It is understandable that when the adjusting member 320 continues to move away from the second cylinder opening 310b, its blocking area on the first cylinder opening 310a gradually increases, thereby gradually reducing the airflow entering the cylinder shell 310 and the channel 110 through the first cylinder opening 310a, thus reducing the airflow. Conversely, when the adjusting member 320 continues to move closer to the second cylinder opening 310b, its blocking area on the first cylinder opening 310a gradually decreases, thereby gradually increasing the airflow entering the cylinder shell 310 and the channel 110 through the first cylinder opening 310a, thus increasing the airflow.

[0066] In another embodiment, the shell 310 is a tapered cylinder with a gradually decreasing inner diameter, and the trend of the inner diameter change of the shell 310 in the axial direction is opposite to the trend of the outer diameter change of the adjusting member 320. For example, when the outer diameter of the cone 321 is gradually decreasing in the direction from the second opening 310b to the first opening 310a, the inner diameter of the shell 310 is set to gradually increase. In this case, the adjusting member 320 can be completely accommodated within the shell 310. It is understandable that when the adjusting member 320 moves toward the first cylinder opening 310a, the wider end of the adjusting member 320 is driven to gradually move toward the wider inner diameter of the cylinder shell 310, forming a larger ventilation gap between the two, thereby gradually increasing the air volume entering the channel 110 through the second cylinder opening 310b, thus increasing the air volume; conversely, when the adjusting member 320 moves toward the second cylinder opening 310b, the wider end of the adjusting member 320 is driven to gradually move toward the narrower inner diameter of the cylinder shell 310, forming a smaller ventilation gap between the two, thereby gradually decreasing the air volume entering the channel 110 through the second cylinder opening 310b, thus decreasing the air volume.

[0067] Whether the cylindrical shell 310 moves relative to the main shell 100 or the adjusting member 320 moves relative to the main shell 100, there is relative movement between the cylindrical shell 310 and the adjusting member 320 along the axial direction of the cylindrical shell 310. At this time, a stop rib 313 is formed radially protruding from the inner wall of the cylindrical shell 310 near the second opening 310b. The stop rib 313 has a guide hole 313a extending through it along the axial direction of the cylindrical shell 310. The adjusting member 320 also includes a guide protrusion 322 protruding from the wide end toward the narrow end. The guide protrusion 322 is movably inserted through the guide hole 313a along the axial direction of the cylindrical shell 310, and the outer diameter of the guide protrusion 322 is not greater than the outer diameter of the wide end, so that the stop rib 313 limits and stops the wide end during the movement of the adjusting member 320 toward the second opening 310b. In this way, the guide hole 313a and the guide protrusion 322 are slidably connected, so that under the accurate guidance of the guide hole 313a, the relative movement direction of the cylinder shell 310 and the adjusting member 320 is more accurate and the movement process is more stable. Since the stop rib 313 is directly radially protruding from the inner wall of the cylinder shell 310, when the adjusting member 320 moves towards the second cylinder opening 310b to the preset limit position, the stop rib 313 can stop and abut against the wide end of the cone 321, restricting the further movement of the adjusting member 320 and preventing the adjusting member 320 from coming out of the cylinder shell 310.

[0068] In view of the above, the adjustment stroke of the aforementioned adjusting member 320 and / or the cylindrical shell 310 can be directly achieved by manual operation by the user, or it can be automatically driven by a specially designed drive device. When operated manually by the user, the user can directly act on the movable adjusting member 320 and / or the cylindrical shell 310, that is, push or pull the movable adjusting member 320 and / or the cylindrical shell 310 along the axial direction of the cylindrical shell 310. Alternatively, the user can act indirectly on the movable adjusting member 320 and / or the cylindrical shell 310. In one embodiment, the adjusting assembly 300 further includes an operating member 330 and a transmission member 340. The operating member 330 is exposed on the outer wall of the main housing 100 and has a driving stroke that moves relative to the main housing 100 under external force; the transmission member 340 connects the operating member 330 and the movable cylindrical shell 310 and / or the adjusting member 320 to convert the driving stroke into an adjustment stroke.

[0069] The operating element 330 is directly driven by the user. When the driving stroke and the adjustment stroke are in the same direction, the transmission element 340 can perform functions such as synchronous transmission and speed regulation transmission as needed. When the driving stroke and the adjustment stroke are in opposite directions, the transmission element 340 can perform functions such as reversing transmission, speed regulation transmission, and speed regulation transmission as needed. Specifically, as described above, the main housing 100 is generally cylindrical. In this case, to facilitate manual operation by the user, the operating element 330 can be specifically set to drive along the circumference of the main housing 100 / cylindrical housing 310. At this time, the transmission element 340 can convert the circumferential movement of the operating element 330 along the cylindrical housing 310 into the axial movement of the adjustment element 320 along the cylindrical housing 310.

[0070] Specifically, in such Figures 1 to 7 In the structure shown, the cylindrical shell 310 is housed within the channel 110 and includes an inner cylindrical body 311 and an outer cylindrical body 312 that are movably fitted together from the inside to the outside. An adjusting member 320 is movably disposed within the inner cylindrical body 311 and extends at least partially toward the outer cylindrical body 312 to form a guide protrusion 322. A first elongated hole 314 is radially provided on the sidewall of the outer cylindrical body 312. In the circumferential direction of the cylindrical shell 310, the first elongated hole 314 gradually extends obliquely toward one axial end of the cylindrical shell 310. A second elongated hole 120 is radially provided on the main housing 100. The second elongated hole 120 extends along the cylindrical shell... The circumferential extension of 310 is elongated; one end of the operating member 330 is slidably connected to the second elongated hole 120, and the other end is connected to the outer cylinder 312; one end of the transmission member 340 is slidably connected to the first elongated hole 314, and the other end extends into the cylinder 310 and is connected to the guide protrusion 322; under the drive of external force, the operating member 330 moves along the second elongated hole 120, and drives the transmission member 340 to move along the first elongated hole 314 through the outer cylinder 312, so as to convert the circumferential translation of the operating member 330 along the cylinder 310 into the axial translation of the adjusting member 320 along the cylinder 310.

[0071] It should be noted that the above does not constitute a limitation on the fitting depth of the inner cylinder 311 and the outer cylinder 312. That is, depending on actual needs, the inner cylinder 311 can be completely fitted inside the outer cylinder 312, or the inner cylinder 311 can be partially fitted inside the outer cylinder 312.

[0072] The inner cylinder 311 can be a single cylindrical structure or it can be composed of at least two cylindrical structures joined together sequentially. The inner cylinder 311 can be fixed relative to the main shell 100, and can extend outward at least partially through the first air vent 111 as needed. The outer cylinder 312 is movably fitted onto the section of the inner cylinder 311 away from the first air vent 111, and the outer cylinder 312 can be circumferentially rotated relative to the inner cylinder 311.

[0073] The outer cylinder 312 is provided with a first elongated hole 314. The first elongated hole 314 can be provided on one radial side of the outer cylinder 312. Alternatively, the first elongated hole 314 can be provided on opposite sides of the same radial direction.

[0074] The transmission component 340 is specifically a rod, for example. When there is one first elongated hole 314 on each of the opposite sides of the same radial direction, the transmission component 340 can pass through the opposite ends of the guide protrusion 322 radially and then slide and engage with the two first elongated holes 314 on the two sides respectively.

[0075] The main housing 100 is provided with a second elongated hole 120. The operating element 330 may be, for example, a toggle switch, lever, push rod, or push block. Part of the operating element 330 is exposed on the outside of the main housing 100, while the remaining portion extends through the second elongated hole 120 into the channel 110 and is fixedly connected to the outer cylinder 312. The method of fixing the operating element 330 to the outer cylinder 312 is not limited and may include, but is not limited to, snap-fit ​​connections or magnetic connections.

[0076] In actual operation, when the user pushes the operating component 330 towards the circumferential side of the main housing 100, the operating component 330 translates circumferentially along the second elongated hole 120 along the main housing 100, causing the outer cylinder 312 to rotate circumferentially relative to the inner cylinder 311, and then causing the transmission component 340 and the first elongated hole 314 to slide relative to each other. Under the inclined guidance of the first elongated hole 314, the circumferential rotation of the outer cylinder 312 can be converted into the axial translation of the transmission component 340, that is, the axial translation of the adjusting component 320 is ultimately achieved.

Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
