Projector anti-interference heat-dissipation device

Abstract

The invention discloses a projector anti-interference heat-dissipation device. The projector anti-interference heat-dissipation device comprises a projector shell, wherein a left side face of the projector shell is fixedly connected with a bearing; a revolving shaft is arranged in the bearing in a sleeve joint way; an outer surface of the revolving shaft is fixedly connected with a cover body; a bottom end of the cover body is overlapped with the left side face of the projector shell; and the left side face of the projector shell is provided with a first through hole. Through arrangement of aswitch, a suction fan, a micro-servo motor and a filter screen in the projector anti-interference heat-dissipation device, people can control working of the micro-servo motor by operating the switch,and noise generated by the vibration of the micro-servo motor during working is lowered. After finishing of work, the switch is turned off to stop the motor from working. When dust adhering to the filter screen needs to be cleaned, the cover body is rotated and the filter screen is pulled out for cleaning, so that the filter screen is very convenient to clean. Moreover, noise generated by the vibration of the micro-servo motor for heat dissipation of a projector during working can be lowered, so that the environment in which the projector is used is more comfortable.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to an anti-interference heat dissipation device for a projector. Background technique [0002] A projector is an optical instrument that uses optical elements to magnify the outline of a workpiece and project it onto a screen. It can be used for profile measurement with transmitted light, and can also be used to measure the surface shape of a non-through hole and observe the surface of a part with reflected light. The projector is especially suitable for measuring complex contours and small workpieces, such as watch parts, stamping parts, electronic components, templates, molds, threads, gears and forming tools, etc. It has high inspection efficiency and is easy to use; it is widely used in measuring rooms and production workshops. It is especially suitable for the instrumentation and watch industry. [0003] Existing projectors have holes on the casing to ensure effective vent...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a projector anti-interference heat dissipation device, which solves the problem that if the filter screen is not cleaned in time, the dust attached to the filter screen will hinder the smooth circulation of hot air inside the projector, but now The filters are all directly connected to the projector, so it is not very convenient to clean the filter, and the micro-servo motor used for heat dissipation of the projector vibrates and causes noise when it is working, which makes the environment uncomfortable for people when using the projector.
