Problems solved by technology

However, since the above-mentioned cylindrical insect-proof net 230 is fixedly combined on the rotating shaft 221 of the fan rotor 220, not only the cylindrical insect-proof net 230 cannot be firmly fixed on the rotating shaft 221, but also due to the combination of the above-mentioned fan rotor 220 and the The eccentric rotation of the cylindrical insect-proof nets 230 on the rotating shaft 221 of the fan rotor and the unevenness of assembly precision produce eccentricity, and the eccentric rotation of the above-mentioned cylindrical insect-proof nets not only produces noise, but also cannot To maintain the combined state of the insect net, resulting in the problem of weak combination

Abstract

The present invention provides an insect prevention and dust-proof equipment. It is characterized by that said equipment includes drive motor, fan and fan fixed type insect prevention component. The above-mentioned drive motor capable of producing rotating force is mounted on the machine shell, the above-mentioned machine shell interior has air flowpath, the above-mentioned fan is mounted in the above-mentioned air flow path and combined on the above-mentioned drive motor, and rotated to produce pressure difference under the action of rotating force of the above-mentioned drive motor. The above-mentioned fan fixed type insect prevention component is fixed and combined on the above-mentioned fan, and rotated together with fan so as to interrupt the air flowpath and can prevent the insect and dust from flowing into its interior.

Description

technical field [0001] The present invention relates to an anti-insect and dust-proof device, and further relates to an anti-insect and dust-proof device with the following effects: it can not only prevent flying insects and large foreign objects from flowing in with the air flow generated by the rotation of the fan constituting the air supply system To the inside of the equipment, it can also minimize the noise generated and make the bonding state of the parts firm. Background technique [0002] Generally, the air supply system is a system that generates fluid flow, that is, a system that generates air flow by generating a pressure difference of air. The above-mentioned air supply system includes the following structures: a casing (HOUSING), a drive motor and a fan (FAN). The casing has an air flow path; the driving motor is installed inside the casing to generate a rotational force; the fan is rotatably installed in the flow path of the casing, and is rotated by the drivi...
