A heat dissipation and dustproof device for projectors that is beneficial to the principle of centrifugal force

Abstract

The invention relates to the technical field of electronic products, and discloses a heat dissipation and dustproof device for projectors that is beneficial to the principle of centrifugal force. Air intake holes, the two sides of the inner casing are provided with air outlet holes, the inside of the outer casing is fixedly connected with a suction fan, the top of the suction fan is fixedly connected with an air inlet channel, and the top of the air inlet channel is fixed An adsorption layer is connected, the outside of the adsorption layer is fixedly connected with an air inlet partition, the two sides of the suction fan are fixedly connected with an air outlet, and the outside of the air outlet is fixedly connected with a liquid storage box, and the liquid storage The inside of the box is fixedly connected with a partition net, which can achieve the effect of preliminary dust removal through the cooperation of the air inlet net and the adsorption layer, and prevent the fan from inhaling large particles of dust in the air, so as to remove dust from the air entering the projector. Effect.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a heat dissipation and dustproof device for a projector that is beneficial to the principle of centrifugal force. Background technique [0002] Electronic products are related products based on electric energy, mainly including: watches, smart phones, telephones, televisions, DVD players, video recorders, camcorders, radios, tape recorders, combined speakers, CD players, computers, mobile communications, projectors Products such as projectors, among which the projector is mainly a device that can project images or videos onto the screen. It is widely used in homes, offices, schools and entertainment places. Equipped with cooling device.

Problems solved by technology

[0003] However, the existing projectors are usually simply equipped with cooling holes and equipped with fans to assist cooling. This method is not easy to effectively form the internal and external air circulation of the projector, resulting in low cooling effect and affecting the normal operation and service life of the projector. In addition, projectors are mostly used in schools or entertainment venues. Such environments are generally dusty, and existing projectors are often not equipped with dust-proof devices, which makes dust easily enter the interior of the projector, thereby affecting the internal light source of the projector. Components, affect the use of the projector, make the projection unclear, and increase the maintenance and cleaning frequency of the light source components, resulting in a reduction in the service life of the light source components
