V. Description of the invention (1) The present invention relates to a dust-proof button device for an electric device that operates a button opening and closing of an electric device. Conventionally, there is a dust-proof type push button device for operating a push button switch mounted on a printed circuit board of an electric device from the outside of the housing of the electric device, for example, the structure shown in FIG. 7. If the details are described with reference to FIG. 7 again, 71 is a housing of an electric machine, 72 is a printed circuit board provided on the housing 71 of the electric machine, 73 is a push-button switch mounted on the printed circuit board 72, and 74 is provided on the housing 71. The button cover is located at a position of the button operation hole 71a of the casing 71 facing the button switch 73, and is mounted with a bolt 76 through a dust pad 圏 75. To operate the push button switch 73, first remove the bolt 76 and then remove the push button cover 74, and then directly operate the push button switch 73 from the button hole 71a of the casing. However, the above-mentioned conventional architecture requires operation of the push button switch 73 mounted on the printed circuit board 72 inside the casing 71. There is no other way than removing the button cover 74M from the casing 71. There are processing problems, inconvenience in operation, and high cost. Subject. The object of the present invention is to eliminate the above-mentioned problem of the dust-proof push button device of the conventional electric device. Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please fill in this page before the M. Reading &-) In order to achieve the above purpose, the first component of the present invention is to make the button an elastomer and make it There are: an ON / OFF operation part for pressing a push button switch installed in a housing of an electric device, a guide shaft part, a stopper part provided in the middle of the guide shaft part, and a skirt part for imparting resilience to the button, Install this button in the hole of the above casing. At the same time, in the second member of the present invention, in addition to the first member, a flange portion that can be closely adhered to the outer shell is formed at the peripheral end of the skirt of the button: i. With the above-mentioned structure, the first component of the present invention is oriented to be arranged inside the casing. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 father 29 ^ Gongya 473755 Central Government Bureau of the Ministry of Economic Affairs Consumer Cooperatives printed A7 B7 5 Description of the invention (3) Deformation, the guide shaft portion 4c is depressed, the button switch 3 can be ON / OFF, and the button 4 is restored to its original state when the hand is released. The function of the button 4 is to complete the ON / OFF of the button switch 3. Action, while ensuring the dustproofness between the casing 1 and the button 4. (Embodiment 2) The button is designed to reduce the operating force by 3, and the thickness of the skirt must be thin. Therefore, the button is mounted on the casing at the periphery of the skirt. When the button is pressed, it will be deformed, and the adhesion with the casing will be deteriorated. Therefore, the second embodiment shown in Fig. 6 further improves the adhesion between the skirt's peripheral edge of the button and the casing. In Fig. 6, The 4A button is the same as the first embodiment, and 4a to 4d are the same as those in the first embodiment, so the description is omitted. This button 4A is a new flange portion 4e. The flange portion 4e is located on the entire periphery of the skirt 4b. Increase the diameter of the flange Μ The close area of 1. Due to the above structure, the strength of the peripheral end of the skirt portion 4e is increased, and there is almost no deformation when the button is installed or pressed, and the close area to the case 1 is increased, so it can be improved to the case 1. In order to further improve the adhesiveness with the casing 1, the M-bonding agent may join the sealing surface between the flange portion 4e and the casing 1. At this time, there is no change in the button function, and the adhesiveness can be improved. Reliability. ♦ It is clear from the above description that when the first member of the present invention is used, the button is made of an elastic body, and it is provided with an ON / OFF operation part for pressing the button switch, a guide shaft part, and a guide shaft part. The stopper part in the middle of the shaft part and the skirt part that imparts restoring force to the button, and this button is installed in the hole of the above casing. With this simple structure, the button function and dust resistance can be achieved, and the operation is good. And when assembling, it just presses the guide shaft into the hole of the shell.

Description of the invention (4) The installation can be completed easily. At the same time, because the entire button system is formed of M elastomer, it will not exert excessive force on the button switch when it is pressed hard. High, can use a small mold to form buttons, the cost of the mold is low, the excellent effect of the structure suitable for production, etc. The simple description of the figure 1 shows the dust-proof button device of the electrical equipment according to the first embodiment of the present invention Side sectional view.
