Dust-free mouse with secondary light gathering

Abstract

The invention discloses a dust-free mouse with secondary light gathering. The mouse comprises a shell, a bottom plate, a PCB (Printed Circuit Board), an optical sensor, an optical lens assembly, a light emitting diode (LED), a control chip, a light touch key, a microswitch and a roller, wherein the shell and the bottom plate are matched to form a sealing cavity; the bottom plate is made of a light transmitting material; one surface, which is matched with the optical lens assembly, of the bottom plate is provided with an arc-shaped bulge which is matched with the optical lens assembly in a counterpoint way. According to the dust-free mouse, an integrated hole-free mode is adopted, a splicing mode or an embedding mode is not adopted, the bottom plate is completely integrated, no gap exists, and the dustproof effect is ensured while the appearance is attractive; the illumination intensity of the mouse is greatly improved by the adopted secondary light gathering, an IC (Integrated Circuit) can easily reach better identification precision, and the illumination requirement of an LED light emitting light source is reduced.

Description

Technical field [0001] The invention relates to a computer input device, in particular to a dust-free mouse with secondary light concentration. Background technique [0002] The mouse is one of our most frequently operated devices. The advancement of applications has caused people to put forward more requirements on the mouse, including comfortable operation feel, flexible movement and accurate positioning, high reliability, and no frequent cleaning. In computers, the maneuverability of the mouse often plays a key role. With the popularization of computers and other equipment, the mouse has also been popularized, and its production and use are extremely large. [0003] Most of the optical mice in daily use are optical mice, and optical mice judge the position of the cursor through the images fed back by its optical engine, and finally the actual mouse positioning operation. Because of the need to feedback images, the bottom of the optical mouse used is equipped with a lig...

AI Technical Summary

Problems solved by technology

The current mouse only relies on a single condensing light, and its light concentration is poor. It needs to use a high-intensity LED light source to achieve the smooth use of the IC. However, the high-intensity LED light source has a long service life and cost. LED light source with lower illuminance has no advantage
