Temperature-adjustable dustproof cap

Abstract

The invention provides a temperature-adjustable dustproof cap. The temperature-adjustable dustproof cap comprises a cap body, a semiconductor temperature regulation module, an air guiding heat exchange groove, a ventilator and a dust filtration cover, wherein the semiconductor temperature regulation module is arranged on the cap body, the first end face of the semiconductor temperature regulation module and the second end face of the semiconductor temperature regulation module are communicated with the portion inside a cavity of the cap body and the portion outside the cavity of the cap body respectively, the air guiding heat exchange groove is formed in the first end face of the semiconductor temperature regulation module, the ventilator is arranged on the outer wall of the cap body, one part of the air outlet of the ventilator is communicated with the portion near the second end face of the semiconductor temperature regulation module, the other part of the air outlet of the ventilator extends into the cavity of the cap body and is communicated with the air inlet end of the air guiding heat exchange groove, the dust filtration cover is arranged on the outer wall of the cap body, and the air inlet of the ventilator is communicated with the inner portion of the dust filtration cover. When the temperature-adjustable dustproof cap is used, external dust-contained air flow enters the air inlet of the ventilator after being filtered through the dust filtration cover, a part of fresh air enters the air guiding heat exchange groove from the air outlet of the ventilator and exchanges heat with the semiconductor temperature regulation module, and the fresh air with heat exchanged with the semiconductor temperature regulation module is discharged into the cavity of the cap body from the air outlet end of the air guiding heat exchange groove. The temperature-adjustable dustproof cap can provide clean air, the appropriate temperature and a communication environment convenient to use for a wearer.

Description

technical field [0001] The invention relates to the field of production of protective equipment, in particular to a temperature-adjustable dustproof cap. Background technique [0002] In material production (such as the production of cement, ceramics, building materials, refractory materials, glass, etc.), material processing (such as crushing, drilling, grinding, polishing, cutting, etc.), mining, blasting, battery production, furniture production, chemical industry , painting, sand blasting, textiles, agriculture (such as grain harvesting, grain storage, etc.), screening and mixing transportation of crushed materials, foundry industry (such as sand mixing, sand mixing, molding, and casting boxing, sand cleaning, etc.), construction Dust pollution is more serious in industries such as decoration, wall chiseling, painting, grinding, etc., railway road construction (such as tunnel digging, paving, etc.), so dust caps have become an essential production protective equipment fo...

Problems solved by technology

[0004] However, in the actual production process, although the existing dust cap can effectively protect the operator from inhaling dust and debris from the outside, because the external temperature is often high during the production process, the air in the closed dust cap The temperature will become very high. In addition, the carbon dioxide exhaled by the operator is not easy to discharge, which makes the inside of the existing dust cap extremely stuffy and the air circulation is not smooth, which seriously affects the health of the operator and production experience.

[0005] In addition, since the inside of the dust cap needs to be closed, and the working environment using the dust cap is often noisy, it is difficult for the operator wearing the dust cap to communicate with the outside world (such as calling)

This kind of communication obstacle will also bring inconvenience to production and bring safety hazards to operators
