A waterproof membrane with a reset function and a waterproof button

Abstract

The present invention provides a waterproof membrane and a waterproof button with a reset function, the waterproof membrane includes a waterproof membrane body, a pressing column, and an elastic reset part sealingly connecting the waterproof membrane body and the pressing column, and the elastic reset part surrounds the on the outside of the column. By arranging the elastic reset part to seal and connect the waterproof membrane body and the pressing column, the waterproof membrane has good waterproof performance, even if water reaches the upper surface of the waterproof membrane, it is impossible to pass through the waterproof membrane to reach the computer board, and the waterproof membrane is added Excellent waterproof performance, improve the safety of the key; by setting the pressing column, the pressing function of the key switch can be realized, avoiding the opening of a through hole for the key body to pass through on the waterproof membrane, and setting the elastic reset part, so that the pressing column After being pressed down, it can be automatically reset under the drive of the elastic reset part, which saves the spring in the traditional design and reduces the product cost.

Description

technical field [0001] The invention belongs to the technical field of button parts, and in particular relates to a waterproof membrane with reset function and a waterproof button with the waterproof membrane. Background technique [0002] With the continuous improvement of the popularity and extensiveness of home appliances and the increase in the frequency of home appliance safety accidents in recent years, consumers have put forward higher and higher requirements for the safety of home appliances. In response to the voice of consumers, the relevant standards of the home appliance industry require Also continue to improve and improve. For example, washing machines, especially the requirements for the waterproof performance of drum washing machines, although the computer board has been changed from an integrated type of strong and weak electricity to a separate type of strong and weak electricity (only weak electricity on the computer board), it is still impossible to compl...

AI Technical Summary

Problems solved by technology

The waterproofness of the keys of the washing machine is improved by setting the waterproof plate, which can prevent water droplets from flowing into the computer board through the gap between the key and the control panel; The water in the key waterproof board may seep into the computer board through the through hole; and in order to reset the key after it is pressed, it is generally necessary to set a return spring, which makes the key structure complex and expensive
