Remote controller with external surface wrapped with silica-gel soft film

Abstract

The invention discloses a remote controller with an external surface wrapped with a silica-gel soft film. The remote controller is mainly characterized in that external surfaces of a shell of a remote controller body, buttons, an infrared light emitting diode and a battery box cover are wrapped with a layer of white transparent silica-gel soft film with a 0.1-0.3mm thickness; after the battery box cover is wrapped, an edge is used to cut periphery wires so that the battery box cover can be individually moved out from the shell; shore hardness of the silica-gel soft film is controlled to be 23 to 30, tensile strength is controlled to be 7.0-7.5 MPa, an elongation at break is controlled to be 500 to 550% and tear strength is controlled to be 15KN / m. In the invention, dusts in the air, lampblack, water vapor and the like can be prevented from entering into the remote controller from assembling gaps between the remote controller shell and the buttons, and between a glass pipe head of the infrared light emitting diode and the battery box cover; a wireless transceiver module and an infrared transceiver IC module in the remote controller and button contact points can be ensured to be clean and be in a good contact state. By using the remote controller of the invention, an electric appliance can be started flexibly and controlled.

Description

technical field [0001] The invention relates to the technical field of remote controllers, in particular to a remote controller whose outer surface is covered with a soft silicone film. Background technique [0002] The shell, buttons, the glass tube head of the infrared light-emitting diode and the battery box cover of the existing remote control are all exposed in the air. After a period of use, dust, oil fume, water vapor in the air, etc. The assembly gap between the glass tube head of the infrared light-emitting diode and the battery box cover enters the remote control and covers the wireless transceiver module, infrared transceiver IC module and button contacts, resulting in poor contact when the button is pressed, causing the remote control to fail. And can not open, control the electrical appliances. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to improve the deficiencies of the prior art, and to provide a remote controller whose dust, ...
