Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a fan with a wide range of touch control. Background Technology

[0002] Existing touch-controlled fans are widely used in home and office settings due to their advantages such as no mechanical wear and easy operation. Their core functionality is to control start, stop, speed, and other functions by sensing changes in human body capacitance through touch buttons.

[0003] However, most mainstream products currently use independent, small-sized sensing units for their touch buttons. These units can only detect touch signals within a very small area of ​​the button itself. Users need to precisely locate the button to trigger control, resulting in insufficient ease of operation. Especially in real-world scenarios, such as when the user is holding an object, moving, or in low-light environments, the difficulty of accurately touching the button increases significantly, often leading to issues where multiple touches fail to trigger the button.

[0004] To improve the sensing range, some solutions attempt to use large touch circuit boards to increase the touch area. However, due to the limitations of the fan structure layout, there is limited space for expanding the button size. Increasing the size and thickness is also costly, and large components are prone to damage, resulting in significant limitations of the product. Utility Model Content

[0005] The main purpose of this invention is to provide a fan with a wide range of touch control, aiming to achieve a stable and low-cost wide range of touch control effect through a simple structure.

[0006] To achieve the above objectives, this utility model proposes a fan with wide-range touch control, comprising a fan body and a footrest;

[0007] The footrest and the fan body are electrically connected to each other. One side of the footrest facing the fan body is provided with a touch position. The footrest has a mounting cavity, and a control board is provided in the mounting cavity. The control board has a touch spring facing the touch position. A conductive thin layer structure for increasing the sensing range of the touch position is provided between the touch position and the touch spring. One side of the conductive thin layer structure is in close contact with the touch position, and the other side is in close contact with the touch spring.

[0008] In one embodiment of this utility model, there are multiple touch positions, which are spaced apart; there are multiple touch springs relative to the multiple touch positions, and each touch position corresponds to one touch spring.

[0009] In one embodiment of this utility model, each of the touch positions has a functional pattern silkscreened on the side facing the fan body.

[0010] In one embodiment of this utility model, the control board is provided with an indicator light opposite the touch spring. The indicator light is positioned towards the footrest and is spaced apart from the touch spring.

[0011] In one embodiment of this utility model, the inner wall of the mounting cavity is provided with a lampshade facing the indicator light, and the foot platform is provided with a light-transmitting part opposite to the lampshade.

[0012] In one embodiment of this utility model, the fan body includes a rear cover, a drive structure, fan blades, and a face shield; a mounting base is provided on the foot platform, the mounting base is located on one side of the touch position, the rear cover surrounds the outer periphery of the mounting base, the drive structure passes through the mounting base, the fan blades are connected to the drive structure and connected to the side of the mounting base facing the touch position, and the face shield is connected to the rear cover and forms an air cavity for surrounding the fan blades.

[0013] In one embodiment of this utility model, the conductive thin layer structure is one or more of the following: thin copper foil, thin aluminum foil, thin tin foil, conductive cloth, conductive foam, and conductive adhesive with a metal substrate.

[0014] By adopting the above technical solution, this utility model has the following advantages:

[0015] The fan of this utility model includes a fan body and a foot. The foot is connected to a cable and is equipped with a motor and other structures for driving the fan body. The fan body can be stably controlled when mounted on the foot.

[0016] To make the fan's operation more stable and convenient, a touch control is provided on the footrest, and a control board capable of controlling the fan's operating status is located within the mounting cavity of the footrest. The control board includes a touch-sensing signal processing unit, and a touch spring is positioned on the control board facing the touch control. The touch spring is connected to a resistive element and a reference capacitor in parallel. The touch-sensing signal processing unit is connected to the resistive element and can sense the charging time at the resistive element. When the user touches the touch control, the touch spring effectively connects a human body capacitance to the circuit. The two capacitors are connected in parallel, changing the charging time at the resistive element, thereby realizing... The current control board senses the touch state, and this structure can easily achieve operation. However, the sensing range of the spring is limited. Therefore, this utility model provides a conductive thin layer structure between the touch position and the touch spring. The conductive thin layer structure can be tin foil. The above structure is closely attached to the touch position, and the area of ​​the tin foil matches the touch position. This can effectively increase the contact area of ​​the touch spring and improve the sensing area.

[0024] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The following is in conjunction with the appendix Figures 1 to 4 The present invention will be further described below.

[0027] To achieve the above objectives, this utility model proposes a fan with wide-range touch control, comprising a fan body 1 and a footrest 2;

[0028] The footrest 2 and the fan body 1 are electrically connected to each other. One side of the footrest 2 facing the fan body 1 is provided with a touch position 21. The footrest 2 is provided with a mounting cavity 22. The mounting cavity 22 is provided with a control board 4. The control board 4 is provided with a touch spring 41 facing the touch position 21. A conductive thin layer structure 43 is provided between the touch position 21 and the touch spring 41 to increase the sensing range of the touch position 21. One side of the conductive thin layer structure 43 is in close contact with the touch position 21, and the other side is in close contact with the touch spring 41.

[0029] The fan of this utility model includes a fan body 1 and a foot 2. The foot 2 is connected to a cable and is equipped with a motor and other structures for driving the fan body 1. The fan body 1 can be stably operated when mounted on the foot 2.

[0030] To make the fan operation more stable and convenient, a touch position 21 is provided on the footrest 2, and a control board 4 capable of controlling the fan's operating state is provided in the mounting cavity 22 within the footrest 2. The control board 4 is equipped with a touch sensing signal processing unit, and a touch spring 41 is provided on the control board 4 facing the touch position 21. The touch spring is connected to a resistive element and a reference capacitor in parallel. The touch sensing signal processing unit is connected to the resistive element and can sense the charging time at the resistive element. When the user touches the touch position 21, the touch spring 41 is equivalent to connecting a human body capacitor in the circuit. The two capacitors are connected in parallel, changing the charging time at the resistive element, thereby enabling the control board 4 to sense the touch state. This structure allows for easy operation, but the sensing range of the spring is limited. Therefore, this invention provides a conductive thin layer structure 43 between the touch position 21 and the touch spring 41. The conductive thin layer structure 43 can be tin foil. This structure is closely attached to the touch position 21, and the area of ​​the tin foil matches that of the touch position 21. Furthermore, the contact area between the tin foil and the touch position 21 is greater than the contact area between the touch spring 41 and the touch position 21, which can effectively increase the contact area of ​​the touch spring 41 and improve the sensing area. The above structure is simple, and the tin foil can be directly pasted onto the touch position 21, making the overall structure strong and effectively improving the touch range, thus enhancing the user experience.

[0031] The essence of a spring-loaded touch button is to trigger an electronic switch by detecting minute changes in capacitance caused by a finger touch. Combined with a thin guiding layer structure, such as aluminum foil, it ensures a large touch range while reducing the overall cost of the structure.

[0032] In one embodiment of this utility model, multiple touch positions 21 are provided, and the multiple touch positions 21 are spaced apart; multiple touch springs 41 are provided relative to the multiple touch positions 21, and each touch position 21 corresponds to one touch spring 41.

[0033] The fan of this utility model can have multiple functions including starting, stopping, airflow adjustment, and lighting. In order to achieve the above functions, multiple touch springs 41 responsible for different functions can be set on the control board 4 to form electronic switches with different functions, while the foot platform 2 is equipped with touch positions 21, which can realize multi-functional stable control and ensure the user's user experience.

[0034] In one embodiment of this utility model, each touch position 21 has a functional pattern silkscreened on the side facing the fan body 1. Different functional patterns can be set on each touch position 21, which allows users to clearly understand the function of each button and improves the user experience.

[0035] In one embodiment of this utility model, the control board 4 is provided with an indicator light 42 relative to the touch spring 41. The indicator light 42 is positioned towards the footrest 2 and is spaced apart from the touch spring 41.

[0036] Indicator light 42 can inform the user of the fan function currently in use. Furthermore, indicator light 42 is located near touch position 21 and can slightly illuminate touch position 21, enabling the user to use it normally and stably in dim lighting conditions.

[0037] In one embodiment of this utility model, the inner wall of the mounting cavity 22 is provided with a lampshade 23 facing the indicator light 42, and the foot platform 2 is provided with a light-transmitting part 24 opposite to the lampshade 23.

[0038] The lampshade 23 is installed inside the foot 2, which can form a light guide cavity surrounding the indicator light 42, allowing the indicator light 42 to use a lower power LED, which can reduce energy consumption while ensuring a certain brightness, so that users can use it normally in the dark, and has a good energy-saving effect, reducing the cost of use. The light-transmitting part 24 allows users to see the light of the LED directly, ensuring the normal use of the function.

[0039] In one embodiment of the present invention, the fan body 1 includes a rear cover 11, a drive structure 12, a fan blade 13, and a face shield 14; a mounting base 3 is provided on the foot 2, the mounting base 3 is located on one side of the touch position 21, the rear cover 11 surrounds the outer periphery of the mounting base 3, the drive structure 12 passes through the mounting base 3, the fan blade 13 is connected to the drive structure 12 and connected to the side of the mounting base 3 facing the touch position 21, and the face shield 14 is connected to the rear cover 11 and forms a wind cavity for surrounding the fan blade 13.

[0040] By installing a mounting base 3 on the footrest 2, the drive structure 12 can be hidden inside, and the rear cover 11 installed on the mounting base 3 can ensure the strength of the entire structure and prevent the fan from being damaged during use. The fan blade 13 installed on the mounting base 3 can increase the flow stabilization area and ensure the stable operation of the fan blade 13. The fan is protected by the face shield 14, which has a guide groove to guide the direction of the airflow and improve the user experience.

[0041] In one embodiment of this utility model, the conductive thin layer structure 43 is one or more of the following: thin copper foil, thin aluminum foil, thin tin foil, conductive cloth, conductive foam, and conductive adhesive with a metal substrate.

[0042] The conductive thin-layer structure 43 is a thin metal sheet such as thin copper foil, thin aluminum foil, or thin tin foil, which can significantly increase the sensing area of ​​the touch spring 41. Alternatively, a metal substrate can be placed on the conductive adhesive tape to achieve the same function. Corresponding to conductive cloth and conductive foam, it is characterized by both conductivity and flexibility, and can adapt to slight deformation of the spring, making it suitable for scenarios with protection requirements (such as scratch prevention). Through the above structures, the touch range can be increased in a low-cost and high-strength manner, ensuring the user's experience.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
