Description

Double-layer silica gel sealed anti-false touch key Technical Field The utility model relates to the technical field of electronic watches, in particular to an anti-false touch key sealed by double-layer silica gel. Background In modern life, electronic watches have not only been tools for viewing time, but have also been provided with numerous functions such as athletic monitoring, health data recording, message reminding, etc. The abundant functions greatly increase the use frequency of keys on the electronic watch, and simultaneously, higher requirements are also put on the performance of the keys. However, the existing electronic watch keys expose a number of problems during actual use. In terms of anti-false touch performance, an electronic watch is usually worn on a wrist, and when people perform daily activities, the wrist frequently swings and rubs or collides with objects such as clothes and desktops. The buttons are triggered accidentally, for example, when the user lifts his or her hands to arrange the sleeves, the clothes may squeeze the buttons, so that some functions of the watch, such as starting the timer function by mistake and switching the display mode, are started by mistake, which brings unnecessary trouble to the user and affects the user experience. In view of this, we propose a double-layer silica gel sealed anti-false touch key. Disclosure of utility model In order to make up for the defects, the utility model provides the double-layer silica gel sealed anti-false touch key.
