DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a switch foot control structure of the fan of the present invention will be described with reference to the drawings. First, as shown in FIG. 1, the present invention includes a bottom plate 1, an operation surface plate 2, and a pressing piece 3, of which a control circuit board 11 for controlling the motor speed change and operation of the fan is provided inside the bottom plate 1. Are fixedly installed, several lights 111 are installed on the uppermost surface of the control circuit board 11, and contact buttons 112 are provided at appropriate positions on the uppermost surface, respectively.

The operation face plate 2 is installed on the bottom plate 1, and a pair of concave chambers 21 is formed at the position of the control circuit board 11 of the bottom plate 1. A pair of stereotaxic pillars 211 are installed on the concave chamber 21, and the elastic components 22 are fitted into the stereotaxic pillars 211 respectively. At the position where the contact convex button 112 of the control circuit board 11 on the bottom surface is fitted, an introduction column 212 of the concave chamber 21 is installed. Several engaging holes 213 are respectively installed on the inner wall surface and the bottom surface of the concave chamber 21, and several transparent light covers 23 are installed on one side surface of the concave chamber 21 separately from the operation face plate 2.

The pressing piece 3 is a piece adapted to the concave chamber 21 of the operation face plate 2, and the bottom surface corresponds to the positioning convex column 211 and the introducing column 212 of the concave chamber 21. A pressing rod 32 of an appropriate length is provided. In addition, a hook 33 is integrally formed so as to face the peripheral edge of the pressing piece 3 and the hook hole 213 of the concave chamber 21.

In the assembled state, as shown in FIG. 2, the control circuit board 11 is fixedly installed on the bottom plate base 1, and the light 111 is covered with the light cover 23 of the operation surface plate 2. The operation surface plate 2 is fixedly engaged with the bottom plate base 1, and the introduction column 212 on the bottom surface of the concave chamber 21 is fitted with the contact button 112 of the control circuit board 11. The engaging hook 33 of the pressing piece 3 enters the engaging hole 213 of the concave chamber 21 and engages on the outer wall surface of the concave chamber 21 to be located.

The uppermost end of the elastic part 22 is inserted into the positioning cylinder 31 on the bottom surface of the pressing piece 3, and the pressing rod 32 of the pressing piece 3 fits into the introduction column 212 of the concave chamber 21, and the control circuit The plate is located above the contact button 112. As a result, the pressing piece 3 receives the force of the uppermost end of the elastic component 22, floats on the operation surface plate 2, and the hook 33 is positioned on the outer wall surface of the concave chamber 21, thereby pressing the bottom surface of the pressing piece 3. The rod 32 keeps the position above the contact button 112 on the control circuit board 11, and a gap is created between them.

In operation, as shown in FIG. 3, just by pressing the pressing piece 3, the pressing piece 3 sinks into the concave chamber 21 and presses the elastic part 22, and the pressing rod 32 on the bottom surface of the pressing piece 3 also In accordance with the downward movement, the contact button 112 of the control circuit board 11 is pressed, and the control circuit board 11 opens and closes the power supply of the motor of the electric fan and the light 111. At the same time, the circuit design of the control circuit board 11 allows the user to press the pressing piece 3. You can select the appropriate wind power and operating time by pressing continuously. After the confirmation, when the pressing piece 3 is released, the pressing piece 3 is restored to the original position by the elastic component 22, and the recovered state is shown in FIG.

[0011]

[Effect of the invention]

 As described above, the switch foot control structure of the fan of the present invention has the following features and effects. Since the pressing piece 3 is placed on the operation face plate 2 close to the ground, the operator does not need to press and operate with his legs and bend his waist to operate with his hands. The wind power of the fan and the set time of operation are clear, and the operator can check the operation status at a glance. Further, the operation face plate 2 and the pressing piece 3 are provided with a pair of positioning convex columns 211 and positioning cylinders 31 respectively, and cover the elastic components 22. Therefore, when the pressing piece 3 is pressed, the pressing point can be moved up and down horizontally at any one point of the pressing piece 3 so that the operation can be performed smoothly.
