Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as figure 1 , figure 2 and image 3 As shown, it is a structural schematic diagram of the present invention. The working safety helmet with a refrigeration system of the present invention includes a cap shell 4 and a visor 1, and an air-conditioning and refrigeration system is installed on the cap shell 4.

[0026] The hat shell 4 and visor 1 are made of plastic composite insulating material, which is light in weight, high in strength and good in insulation performance; Fix the micro compressor 5 and the micro motor 7, the micro compressor 5 and the micro motor 7 are connected as one, light in weight and small in size. In recent years, the micro compressor technology has made great progress. The weight can be reduced to about 100 grams, and the volume can be reduced to only the size of the No. 5 battery. For a refrigeration system with a cooling capacit...

Abstract

The invention discloses a working safety helmet with a refrigerating system. The working safety helmet comprises a helmet shell and a helmet peak, wherein the air conditioner refrigerating system is installed on the helmet shell and comprises a micro compressor, a micro motor for driving the micro compressor to work, and a storage battery for supplying electric power to the micro motor, the storage battery is provided with a power supply control switch, a high-pressure end exhaust opening of the micro compressor is connected with a condenser and an evaporator sequentially, a throttle valve or a capillary tube is arranged at the joint of the condenser and the evaporator, an outlet of the condenser is connected with an inlet of the evaporator through the throttle valve or the capillary tube, an outlet of the evaporator is connected with a low-pressure end air inlet of the micro compressor, the evaporator is arranged in the helmet shell, the condenser is arranged outside the helmet shell, the air conditioner refrigerating system is formed in the safety helmet, a refrigerating surface is formed in the safety helmet, and a radiating surface is formed at the outer part of the safety helmet, so that a worker wears the working safety helmet safely and comfortably and feels cool in a high-temperature environment, and a remarkable heatstroke preventing and cooling effect is achieved.

Description

technical field [0001] The invention relates to a safety helmet, in particular to a working safety helmet with a refrigeration system. Background technique [0002] As a safety protective device, hard hats play an effective role in protecting workers' heads from damage or reducing injuries during production operations. Workers call hard hats life-saving hats. But, the safety helmet used at present is not obvious in the effect of heatstroke prevention and cooling. [0003] For the power system, most of the power construction and power repairs are carried out in the hot high temperature and in the open air. Especially in the hot summer, strong sunlight irradiates the head, causing the intracranial temperature to increase, and the staff are prone to heatstroke. People with heatstroke may experience severe headaches, dizziness, nausea, vomiting, tinnitus, vertigo, irritability, mental disturbance, and coma in severe cases, which will cause major safety hazards. Therefore, for...
