Problems solved by technology

[0002] Particles are produced during operations such as mining, casting, metal smelting, and grinding machines. These particles will enter people's respiratory system and cause acute or chronic health problems, and even death. Therefore, it is necessary to wear a mask or a protective mask. The protective effect of the mask is very poor, and it cannot play a good protective role. The protective mask is well-made and can play a good protective effect. However, the existing protective mask is expensive to manufacture, and the protective mask is used when the dust concentration exceeds the standard. Face masks are also unsafe

Abstract

The invention discloses a novel dustproof mask comprising a front mask unit, a rear mask unit, an inspiration filtering valve, an expiration valve and an excessive dust alarming device. Shutters are arranged in the middle of the front mask unit; the excessive dust alarming device is installed on the inner side of the front mask unit adjacent to the shutters; the inspiration filtering valve and the expiration valve are arranged on the rear mask unit, and the front mask unit and the rear mask unit are connected correspondingly. The mask is capable of proofing dust, smoke and other particles effectively, and the wide application range is provided. When the dust intensity of surroundings is excessively high, a first light-emitting diode emits red light to warn operators in excessively high dust intensity of surroundings, operation is improper, operation in high dust intensity is eliminated, safety operation can be benefited for the operators, and the novel dustproof mask has the advantages of simple usage, easiness for washing and low manufacture cost and has the promotion and application value.

Description

technical field [0001] The invention relates to a personal protective device, in particular to a novel dust protective mask. Background technique [0002] Particles are produced during operations such as mining, casting, metal smelting, and grinding machines. These particles will enter people's respiratory system and cause acute or chronic health problems, and even death. Therefore, it is necessary to wear a mask or a protective mask. The protective effect of the mask is very poor, and it cannot play a good protective role. The protective mask is well-made and can play a good protective effect. However, the existing protective mask is expensive to manufacture, and the protective mask is used when the dust concentration exceeds the standard. Face coverings are also unsafe. Contents of the invention [0003] The object of the present invention is just to provide a kind of novel dust protective mask in order to solve the above problems. [0004] The present invention achiev...
