Description

Technical Field

[0001] This utility model belongs to the field of electric fan control technology, and specifically relates to a wind power control structure for electric fans. Background Technology

[0002] Electric fans, as commonly used cooling devices, mostly employ mechanical button adjustments for their fan speed control, allowing users to switch between different speed levels by pressing the button. Currently, these control buttons utilize built-in compression springs to achieve reset after being pressed. However, this structure commonly suffers from springback failure after prolonged use; under high-frequency use, the spring structure's rebound efficiency can decrease by more than 30% within 3-6 months.

[0003] In existing technologies, the rebound failure of wind power control buttons is mainly caused by the following factors: spring fatigue and aging. Traditional buttons use cylindrical helical springs. When used beyond a certain limit, dust and oil accumulate in the gap between the button and the housing. In humid environments, dust agglomerates, increasing frictional resistance. Actual measurements show that dust accumulation can increase the button's reset resistance by 40%-60%. Furthermore, the fit between the button and the guide post wears down during long-term pressing, causing the button to wobble and further exacerbating the eccentric force on the spring. Experimental data shows that when the spring's eccentric angle exceeds 5° after wear, the probability of rebound failure increases by 50%. This degrades the user experience. In home settings, elderly users may accidentally press other settings because the button requires multiple presses to reset. This also reduces the reliability of the function: incomplete rebound can lead to poor contact in the gear switch, and in severe cases, short circuits. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wind power control structure for electric fans.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a wind power control structure for an electric fan, comprising:

[0006] A support assembly, comprising a top plate and a bottom plate, wherein a side plate is fixedly installed on one side of the top plate and the bottom plate;

[0007] The pressing assembly includes four buttons, all located at the top of the top plate. The bottom of each button extends through to the top of the top plate and has an inner rod.

[0008] A guide assembly, the guide assembly including an outer ring, on the surface of which a guide block is fixedly mounted;

[0009] A guide assembly, the guide assembly including a sliding plate, the sliding plate being located between the button and the side plate, the top of the sliding plate having equally spaced inclined grooves;

[0010] The return assembly includes a first component and a second component, the surfaces of which are fitted together with tension springs.

[0011] Preferably, the surface of the button is slidably fitted with a graphene ceramic composite ring embedded in the top plate, the bottom of the inner rod is fixedly fitted with a fixing member that is fixedly connected to the bottom plate, and the surface of the inner rod is fitted with a spring, the two ends of the spring being fixedly connected to the fixing member and the bottom of the button respectively.

[0012] Preferably, the top of the inner rod extends through the interior of the button component and is fixedly installed with mutually symmetrical snap-fit ​​components, and the interior of the button component is provided with snap-fit ​​grooves for engaging with the snap-fit ​​components.

[0013] Preferably, the outer ring is sleeved on the surface of the button and fixedly connected to the button. The outer ring is located at the bottom of the top plate. Guide grooves are provided at equal intervals on one side of the side plate. The guide grooves are used in conjunction with guide blocks for movement guidance.

[0014] Preferably, the number of inclined grooves is the same as the number of guide blocks, and the interior of the moving plate is provided with vertical grooves and horizontal grooves that communicate with the inclined grooves. There are three horizontal grooves, and a snap-fit ​​protrusion is formed between the inclined grooves and the horizontal grooves.

[0015] Preferably, one end of the first component is fixedly installed with a fixing block 1 that is fixedly connected to the bottom of the moving plate, and one end of the second component is fixedly installed with a fixing block 2 that is fixedly connected to one side of the top plate and located at the bottom of the moving plate.

[0016] Preferably, a slide rail is fixedly installed on one side of the moving plate, and a slide groove is provided on one side of the top plate to cooperate with the slide rail for sliding.

[0017] Preferably, a second side plate is fixedly installed on the other side of the top plate and the bottom plate, and the second side plate has a wire hole inside.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. In this invention, when the button is pressed, the graphene ceramic composite ring works in conjunction with the button to guide its longitudinal movement. The graphene ceramic composite ring is a composite material of a ceramic ring and a graphene coating, and its inherent material properties result in a low coefficient of friction, facilitating the pressing and movement of the button. The sliding gap between the graphene ceramic composite ring and the button reduces dust ingress, while its inclined top design further guides dust, making it easy to wipe clean. This improves dustproof efficiency while reducing user maintenance costs; users can directly wipe the surface of the graphene ceramic composite ring externally, eliminating the need for cumbersome disassembly and cleaning.

[0020] 2. When the operator presses the corresponding button, the button causes the corresponding spring to contract. The tilting groove, in conjunction with the guide block, guides the movement of the sliding plate laterally, stretching the tension spring. The button, guided by the tilting groove and the return stroke of the sliding plate, falls into the horizontal groove, preventing the corresponding spring from extending. At this point, the electric fan activates at the airflow corresponding to the pressed button. During button operation, the snap-fit ​​component and snap-fit ​​groove, along with the guide block and guide groove, work together to further guide the button's longitudinal movement. This design effectively solves the problem of button misalignment caused by structural wear and ensures spring performance through the inner rod's sleeve, improving the reliability of the electric fan control structure and the user experience.

[0036] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0037] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0038] refer to Figures 1-8 A wind power control structure for an electric fan, comprising:

[0039] Support component 1 includes a top plate 101 and a bottom plate 102, and a side plate 103 is fixedly installed on one side of the top plate 101 and the bottom plate 102.

[0040] Press component 2, which includes four button components 201, all of which are located at the top of the top plate 101. The bottom of each button component 201 extends through to the top of the top plate 101 and is provided with an inner rod 203.

[0041] Guide component 3 includes an outer ring 301, and a guide block 302 is fixedly mounted on the surface of the outer ring 301;

[0042] The guide component 4 includes a sliding plate 401, which is located between the button 201 and the side plate 103. The top of the sliding plate 401 is provided with inclined grooves 402 at equal intervals.

[0043] The return assembly 5 includes a first block 501 and a second block 502, and tension springs 505 are sleeved on the surfaces of the first block 501 and the second block 502.

[0044] Specifically, when the operator presses the corresponding button 201, the button 201 causes the corresponding spring 205 to contract. The tilting groove 402, in conjunction with the guide block 302, guides the movement of the sliding plate 401 laterally, causing the tension spring 505 to stretch. Guided by the tilting groove 402 and the return stroke of the sliding plate 401, the button 201 falls into the horizontal groove 404, preventing the spring 205 of the corresponding button 201 from extending. At this time, the electric fan turns on with the corresponding external fan speed. During the operation of the button 201, the snap-fit ​​piece 206 and snap-fit ​​groove 207, along with the guide block 302 and guide groove 303, provide further longitudinal guidance for the button 201's movement. This design effectively solves the problem of button 201 offset caused by structural wear and, with the inner rod 203, ensures the use of the spring 205, improving the reliability of the electric fan control structure and the user experience.

[0045] The surface of the button 201 is slidably fitted with a graphene ceramic composite ring 202 embedded in the top plate 101. The bottom of the inner rod 203 is fixedly fitted with a fixing member 204 that is fixedly connected to the bottom plate 102. A spring 205 is fitted onto the surface of the inner rod 203. The two ends of the spring 205 are fixedly connected to the fixing member 204 and the bottom of the button 201, respectively. The graphene ceramic composite ring 202 works with the button 201 to achieve longitudinal movement guidance. Its own coefficient of friction is low, which facilitates the pressing and moving of the button 201. The sliding gap between the graphene ceramic composite ring 202 and the button 201 reduces the entry of dust. The inclined design of its top makes it easier to guide the dust and make it easier to wipe and clean the dust.

[0046] The top of the inner rod 203 extends into the interior of the button component 201 and is fixedly installed with mutually symmetrical snap-fit ​​parts 206. The interior of the button component 201 is provided with snap-fit ​​grooves 207 that engage with the snap-fit ​​parts 206. The mutual snap-fit ​​between the snap-fit ​​parts 206 and the snap-fit ​​grooves 207 enables the button component 201 to move on the surface of the inner rod 203 while also helping the button component 201 to achieve angular positioning.

[0047] The outer ring 301 is sleeved on the surface of the button 201 and is fixedly connected to the button 201. The outer ring 301 is located at the bottom of the top plate 101. The side plate 103 has guide grooves 303 at equal intervals on one side. The guide grooves 303 work with the guide block 302 to guide the movement. When the button 201 moves, it will drive the outer ring 301 and the guide block 302 to move synchronously. The guide grooves 303 work with the guide block 302 to guide the movement, thereby achieving the guiding and limiting of the longitudinal movement of the button 201.

[0048] The number of inclined grooves 402 is the same as that of guide blocks 302. The interior of the moving plate 401 is provided with vertical grooves 403 and horizontal grooves 404 that communicate with the inclined grooves 402. There are three horizontal grooves 404. A locking protrusion 405 is formed between the inclined grooves 402 and the horizontal grooves 404. The four inclined grooves 402 cooperate with the guide blocks 302 to cause tilting guidance during movement, resulting in the lateral movement of the moving plate 401. The corresponding guide blocks 302 will form a locking with the locking protrusion 405 after movement.

[0049] One end of component block 501 is fixedly installed with a fixing block 503 that is fixedly connected to the bottom of the moving plate 401. One end of component block 502 is fixedly installed with a fixing block 504 that is fixedly connected to one side of the top plate 101 and located at the bottom of the moving plate 401. Fixing block 503 provides support and fixation for component block 501, and fixing block 504 provides support and fixation for component block 502.

[0050] A slide rail 506 is fixedly installed on one side of the sliding plate 401, and a slide groove 507 is provided on one side of the top plate 101 to cooperate with the slide rail 506 for sliding. The slide rail 506 and the slide groove 507 are slidably connected to guide the sliding plate 401 to move on one side of the top plate 101.

[0051] Side plate 2 6 is fixedly installed on the other side of top plate 101 and bottom plate 102. Side plate 2 6 has a wire hole 601 inside. Side plate 2 6 provides support for top plate 101 and bottom plate 102, and wires are passed through it in conjunction with button 201 through wire hole 601. This is a well-known technical field. It will not be described in detail here.

[0052] Brief description of usage: Three buttons 201 on one side of the top plate 101 can be connected to control drives for different wind speeds through wiring holes 601, while one button 201 on the other side is an unlocking button. During use, when the operator presses the button 201 that controls the wind speed, its graphene ceramic composite ring 202 works in conjunction with the button 201 to guide longitudinal movement. The button 201 slides on the surface of the inner rod 203, and the corresponding spring 205 contracts. Simultaneously, the button 201 drives the outer ring 301 and guide block 302 to move synchronously. The guide groove 303, in conjunction with the guide block 302, guides and limits the longitudinal movement of the button 201. When the inclined groove 402 moves in conjunction with the guide block 302, the inclined guide causes the moving plate 401 to move laterally, and the tension spring 505 is stretched accordingly. Under the guidance of the inclined groove 402 and the return motion of the moving plate 401, the button 201 falls into the horizontal groove 404. After being engaged by the locking protrusion 405, the spring 205 corresponding to the button 201 cannot extend. At this time, the electric fan turns on and the external fan airflow corresponding to the button 201 is turned on.

[0053] When the fan needs to be unlocked, the unlocking button 201 on the other side of the sliding plate 401, after being pressed, first moves the sliding plate 401 via the tilting groove 402. After the corresponding guide block 302 slides into the vertical groove 403, the previously restricted button 201 is released from the horizontal groove 404 and reset to its initial position under the action of the spring 205. The button 201 that was just pressed returns to its initial state without obstruction under the action of the corresponding spring 205. At this time, all buttons 201 are restored to their initial state. When the desired airflow button 201 is pressed, the previously pressed button 201 will be unlocked and released in the same way. The button 201 that was just pressed is restricted from being energized to transmit the corresponding signal. Through the guiding cooperation of the tilting groove 402 and the vertical groove 403 and the reset mechanism of the spring 205, the interlocking and signal switching of the buttons 201 are realized.

[0054] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
