[Prior art]

 Generally, the control switches of known electric fans are located on the stand of the electric fan. The several pushbuttons mounted on the stand are in close proximity to each other, most often in the form of four buttons. One of them is a stop button, and the other three are control switch buttons for selecting the rotation speed. By selecting and pressing an arbitrary speed switch, the electric fan is operated and the purpose of controlling the wind speed is achieved. On the other hand, the structure of a control switch of a known electric fan is operated by pressing a push button with a hand. Therefore, its area is too small for the area of the leg when we step on it. Moreover, the distance between the switch buttons is very short, and if the user steps on the switch with his / her foot, it is impossible to press the required switch button accurately. On the contrary, there is a danger of inadvertently pressing two or even three buttons at the same time. This often leads to malfunctions, greatly shortening the service life of the entire control switch, and in severe cases, sparking at the point of contact of the compression circuit code of the control switch with danger.

[0005]

[Embodiment of the invention]

 As shown in FIG. 1, the present invention mainly includes a push button switch device 1 and an auxiliary compression device 2. The push button switch device 1 is used for controlling the rotation speed and power supply of the electric fan. The push-button switch device 1 has a rectangular main body 10 on which a number of mechanical compression parts 11 are arranged and installed. At the top end of the mechanical compression part 11, a convex body 12 is stretched upward and installed. On both sides of the convex body 12, a pair of engagement lock portions 13 depressed inside are formed. Pressing any one of the compression components 11 (usually a push button for the convenience of pressing) causes the expected control action (wind speed or selection of on, off, etc.). The push button switch device 1 is a combination of known components, which is often found on an electric fan, and has nothing to do with the improvement of the present invention. The use of the push button switch device 1 must always be adapted.

The auxiliary compression device 2 corresponds to each of the compression parts 11 and has an independent compression arm 20. At one end of the compression arm 20, a push button 21 is installed, in which the compression arm 20 is biased and rotated to push downward. A tank hole 200 is installed in the compression arm 20 on the end side of the push button 21, and a convex column 30 (see FIG. 2) extending into the tank hole 200 is installed inside the stand 3 corresponding to the tank hole 200. I do. As a result, the end has a good stability control effect, and the opposite end of the push button 21 away from the compression arm 20 extends into an appropriate position inside the stand 3 (FIG. 2). See). The extension end is fixed inside the stand 3 and forms a support point 22. Between the support point 22 and the compression arm 20, an elastic thin piece 26 integrally molded is used to connect and form. Thereby, when the compression arm 20 is pushed, good and reliable operability is provided, and the compression arm 20 located at the end side of the elastic thin piece 26 is provided with a notch 27. Guard walls 28 are formed on both sides of the notch 27, and correspond to the guard body 31 inside the stand 3 and extend into the notch 27. Thereby, the end of the compression arm 20 can provide a stable support effect.

The compression surface of the push button is exposed on the stand 3 (see FIG. 5), and the compression arm 20 is set over the convex body 12 at the top end of the compression component 11 (see FIG. 3). In addition, a concave engagement tank 23 is provided corresponding to the arm surface position of the convex body 12. A notch 24 is formed in the intermediate tank wall of the engagement tank 23, and a convex bar 25 is provided on the inner wall of the notch 24 so as to protrude from the engagement lock portion 13 recessed inward on both sides of the convex body 12. Accordingly, when the engagement tub 23 and the convex body 12 are fitted to each other, the engagement tub 23 utilizes the installation of the notch 24 and produces an expansion effect after receiving the fitting of the convex body 12. . In this manner, the convex bar 25 inside the engagement tank 23 and the engagement lock portion 13 recessed inside both sides of the convex body 12 are smoothly fitted and positioned with each other. When the push button 21 is pressed (see FIG. 6), the support point 22 is set as a support end, and the compression arm 20 descends and rotates. The downward movement of the compression arm 20 pushes the compression component 11 to cause a control operation (selection of wind speed, operation stop, etc.).

With the above-described installation, the distance d1 between the compression parts 11 on the push button switch device 1 is extended to d2 by using the auxiliary compression device 2 (the distance d2 in FIGS. 1 and 4 is d1). Greater than the distance). Accordingly, the distance between the push buttons 21 (see FIG. 5) exposed and protruding on the stand 3 is also extended, and the user presses the push buttons 21 with the feet, and the rotation speed of the electric fan, or Accurate selection and control of turning off the electric fan during operation is possible. Further, the push button 21 has good elasticity in order to recover after being pushed. That is, the elastic part 4 is provided between the compression part 11 of the push button switch device 1 and the outer peripheral position of the engagement tank 23 of the corresponding compression arm 20. As a result, when the push button 21 is switched to the stop state, the compression component 11 that was originally pressed quickly recovers and returns to the original position. Further, the elastic component 4 may be of a type that engages with the bottom of the stand 3 below the push button 21 as shown in FIG. Regardless of which method is used, the elastic component 4 can provide a good recovery force after being uniformly pressed by the push button 21.
