Neck entangled type air purifier

Abstract

The invention relates to a neck entangled type air purifier. The air purifier comprises a mask matched with the face of a worker, the mask is provided with an air inlet, the air inlet is connected with one end of an arch-shaped shell, the bending outline of the arch-shaped shell is matched with the neck outline of the worker, a first filtering unit is arranged in the arch-shaped shell and is communicated with the outside, an induced draft fan is arranged on an air outlet of the first filtering unit, an air outlet of the induced draft fan is communicated with the air inlet of the mask, and an air outlet is formed in the mask and is connected with the other end of the arch-shaped shell; a second filtering unit is further arranged in the arch-shaped shell, and an air inlet of the second filtering unit is communicated with the air outlet of the mask; and an air outlet of the second filtering unit is communicated with the exterior. The worker can conveniently wear the air purifier on the neck, the wearing manner is simple, the induced draft fan guides cleaned air into the mask, then, the cleaned air is guided into the second filtering unit from the mask via the air outlet, the air flow of the whole purifier can form a locally-opened loop system, the problem that the due to breathing of the worker, local pressure of the mask is too large, and the efficiency of the induced draft fan is reduced is solved, and the wear comfort of the mask is improved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a neck-wrapping air cleaner. Background technique [0002] Coal mines, quarries, cement plants, construction and metallurgy and other high-dust operating environments will cause great harm to the respiratory system of the workers. If the workers in the above-mentioned operating environments do not have effective protection measures, the dust will Excessive alveolar deposition in the worker's respiratory system will cause diffuse fibrosis of the worker's lung tissue and form pneumoconiosis, which can even cause death in severe cases. In view of the above problems, workers in the above-mentioned working environment are generally equipped with dust masks, while ordinary filter masks are not suitable for high-dust working conditions. There are still many problems with air-supplied masks, such as batteries and The safety of the fan cannot be used in places with high dust (ex...

AI Technical Summary

Problems solved by technology

[0002] Coal mines, quarries, cement plants, construction and metallurgy and other high-dust operating environments will cause great damage to the respiratory system of the workers. If the workers in the above-mentioned operating environments do not have effective protection measures, the dust will Excessive alveolar deposition in the respiratory system of the worker will cause diffuse fibrosis in the lung tissue of the worker and form pneumoconiosis, which can even cause death in severe cases

In view of the above problems, workers in the above-mentioned working environment are generally equipped with dust masks, while ordinary filter masks are not suitable for high-dust working conditions. There are still many problems with air-supplied masks, such as batteries and The safety of the fan cannot be used in places with high dust (explosive environment) such as underground coal mines. Air-supplied masks basically set the air purification part on the waist of the operator, which not only is not comfortable to wear, but also hinders normal work.

If the power of the selected fan is low, the operator will have a feeling of suffocation due to insufficient air supply, and the wearing comfort will be seriously reduced. If the power of the selected fan is high, the noise of the fan will be louder, which will also affect the wearing comfort sex
