Compared with the fan with fan blades, there is no situation where the fan blades fall off and hurt the user, and it is safer to use, so it is more popular among the public.

[0038] However, most of the existing bladeless fans 100 are controlled at the bottom, and users need to bend down to operate when performing operations, and the human-computer interaction is not friendly enough.

[0039] In view of the above problems, the present utility model provides a foot switch structure, which can turn on and off the bladeless fan 100 and adjust the output power of the bladeless fan 100 by stepping on it with the foot, eliminating the need for the user to bend down to operate, and having the characteristics of convenience and speed.

[0040] The technical solutions of the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0041] Figure 1 It is a schematic diagram of the overall structure of the bladeless fan shown in the embodiment of the present utility model;

[0042] Figure 2 It is a schematic diagram of the structure of the base shown in the embodiment of the present utility model;

[0043] Figure 3 It is another schematic diagram of the structure of the first foot switch shown in the embodiment of the present utility model;

[0044] Figure 4 It is a schematic diagram of the structure of the second foot switch shown in the embodiment of the present utility model.

[0045] Please refer to Figures 1 to 4 A foot switch structure provided by an embodiment of the present utility model includes a base 1 having a chamber and at least two openings 10, and the base 1 is used for installing the bladeless fan 100;

[0046] A switch mechanism 2 is arranged in the chamber and includes a first foot switch 21 and a second foot switch 22. The first foot switch 21 is used to start or stop the bladeless fan 100, and the second foot switch 22 is used to adjust the output power of the bladeless fan 100; the movable ends of the first foot switch 21 and the second foot switch 22 both expose out of the opening 10.

[0047] By arranging the first foot switch 21 for controlling the on / off of the bladeless fan 100 and the second foot switch 22 for controlling the output power of the bladeless fan 100 on the base 1, when in use, the user can turn on / off the bladeless fan 100 and adjust the air volume by stepping on the first foot switch 21 and the second foot switch 22, eliminating the need for the user to bend down to operate and improving the use experience of people with limited mobility.

[0048] In a possible implementation, the first foot switch 21 includes a first mounting base 210, an input wiring terminal 211, an output wiring terminal 212, a first conductive sheet 213, and a rotating part 214;

[0049] The first mounting base 210 is arranged in the chamber;

[0050] The input terminal 211 is disposed within the first mounting base 210 and is connected to the live wire;

[0051] The output terminal 212 is disposed within the first mounting base 210 and is connected to the bladeless fan 100;

[0052] The first conductive sheet 213 is rotatably disposed within the first mounting base 210 and can conduct the input terminal 211 and the output terminal 212;

[0053] The rotating portion 214 is rotatably disposed on the first mounting base 210. The rotating portion 214 has opposite first and second ends. The first end is exposed from the opening 10, and the second end abuts against the first conductive sheet 213. When the rotating portion 214 rotates, the second end toggles the first conductive sheet 213 to control the conduction or disconnection between the input terminal 211 and the output terminal 212.

[0054] Specifically, please refer to Figure 3 , when rotating, the second end of the rotating portion 214 can move on the conductive sheet. When it moves from the area of the output terminal 212 to the input terminal 211, it pushes the conductive sheet to connect to the input terminal 211, thereby starting the bladeless fan 100. When the second end of the rotating portion 214 rotates to the input terminal 211, the second end of the rotating portion 214 pushes the conductive sheet to rotate, so that the output terminal 212 is disconnected from the conductive sheet.

[0055] In a possible implementation, the rotating portion 214 of the above foot switch structure includes a spring 214a, a dial cylinder 214b, and a first foot pedal 214c; the spring 214a is vertically disposed in the middle of the first foot pedal 214c, the dial cylinder 214b is connected to the spring 214a, the dial cylinder 214b contacts and abuts against the first conductive sheet 213, the middle of the first foot pedal 214c is hinged to the first mounting base 210, and the first foot pedal 214c drives the dial cylinder 214b to rotate when rotating, so as to control the conduction or disconnection between the input terminal 211 and the output terminal 212.

[0056] Specifically, when the user steps on the first foot pedal 214c, the first foot pedal 214c rotates, driving the spring 214a and the dial cylinder 214b to rotate, so that the bottom end of the dial cylinder 214b can touch another position of the conductive sheet, thereby causing the conductive sheet to rotate and be connected or disconnected from the output terminal 212. During this process, the spring 214a provides an elastic force to the dial cylinder 214b, thereby reducing the contact pressure between the dial cylinder 214b and the conductive sheet and ensuring the smooth rotation of the first foot pedal 214c.

[0057] In a possible implementation, the first conductive sheet 213 of the above-mentioned foot switch structure is arranged in a V-shaped structure. The middle part of the first conductive sheet 213 is hinged to the first mounting seat 210. The first conductive sheet 213 is connected to the input terminal 211. One end of the first conductive sheet 213 is arranged opposite to the output terminal 212. When the dial 214b rotates towards the output terminal 212, the input terminal 211 is electrically connected to the output terminal 212; when the dial 214b rotates towards the input terminal 211, the output terminal 212 is disconnected from the input terminal 211. The conductive sheet is arranged in a V-shaped structure. The V-shaped conductive sheet is hinged to the first mounting seat 210 through the middle part, so that the conductive sheet can rotate on the first mounting seat 210. In this setting, the firmness of the conductive sheet can be improved, and loosening and displacement can be avoided.

[0058] In a possible implementation, the second foot switch 22 of the above-mentioned foot switch structure includes a second mounting seat 220, a rotating shaft 221, a plurality of damping components 222, a resistance sheet 223, a second conductive sheet 224 and a second foot pedal 225;

[0059] The second mounting seat 220 is arranged in the chamber; connecting seats are arranged on both sides of the second mounting seat 220;

[0060] The rotating shaft 221 is arranged in the middle of the second foot pedal 225 and passes through the connecting seats at both ends. A plurality of damping components 222 are arranged on the rotating shaft 221. The damping component 222 includes a gasket and a damping washer arranged in a stacked manner. The connecting seat and the rotating shaft 221 can rotate relative to each other and squeeze the damping washer;

[0061] The resistance sheet 223 is arranged in the second mounting seat 220 and is arranged in an arc shape. The resistance sheet 223 is connected to the live wire;

[0062] The second conductive sheet 224 is connected to the rotating shaft 221 and is in contact with the resistance sheet 223. The second conductive sheet 224 is connected to the first foot switch 21;

[0063] The second foot pedal 225 is exposed from the opening 10. When the second foot pedal 225 rotates, the second conductive sheet 224 rotates around the axis of the rotating shaft 221 to change the position where the second conductive sheet 224 abuts against the resistance sheet 223.

[0064] Specifically, please refer to Figure 4, the second foot pedal 225 and the second mounting base 220 are connected by a rotating shaft 221, and a damping component 222 is arranged on the rotating shaft 221. When a set of damping components 222 is forced to rotate, several damping components 222 rotate synchronously, and the damping washers in each damping component 222 move relative to the gaskets to generate frictional force, ensuring that the second foot pedal 225 can be fixed at various angles during the rotation process.

[0065] Among them, the resistance sheet 223 realizes different resistance outputs through the second conductive sheet 224, thereby controlling the power output of the bladeless fan 100.

[0066] The rotation of the second foot switch 22 has the characteristic of simple operation, which greatly facilitates the user to control the output power of the bladeless fan 100 by stepping on the second foot pedal 225, eliminating the need for the user to bend down to operate.

[0067] In a possible implementation, the thickness of the second foot pedal 225 of the above foot switch structure increases from both ends towards the middle. The thickness of the second foot pedal 225 decreases from the middle towards both ends. With this setting, the rotation amplitude of the second foot pedal 225 can be increased, and the resistance control of the resistance sheet 223 can be further improved, ensuring that a wide range of power outputs can be achieved.

[0068] In a possible implementation, anti-slip sheets are provided on the end face of the first foot switch 21 away from the base 1 and the end face of the second foot switch 22 away from the base 1 of the above foot switch structure, and are respectively fixed on the first foot switch 21 and the second foot switch 22 by bolts.

[0069] In a preferred embodiment, the material of the anti-slip sheet is rubber.

[0070] Compared with the prior art, the foot switch structure provided by the present utility model is arranged on the base 1, and the user can control the bladeless fan 100 by stepping on it, which has the characteristics of simple structure, convenience and speed.
