Abstract

The harm of haze and dust to human bodies is obvious. According to the invention, a wet type anti-haze mask is designed so as to effectively resist the harm of the haze and the dust to the human bodies. The wet type anti-haze mask is mainly composed of a wet mask 6, a frame 8, a unidirectional exhalation tube 1 and a soft bag layer 9. Turbid gas, generated from breathing of a human body, is purified when passing through the wet mask 6 and then the purified turbid gas enters an inhalation cavity, and then enters a respiration cavity 5 by virtue of a unidirectional inclined porous plate 3, so that the purified gas can be inhaled by the human body. When the turbid gas is exhaled, the inclined porous plate 3 is covered by a movable plate 4, so that the turbid gas can only be discharged from the unidirectional exhalation tube 1; therefore, the function of purifying air is completed. Since the wet mask 6 is relatively large in area, breath is kept smooth. By keeping the wet mask 6 from direct contact with a face, the generation of discomfort is avoided. The wet type anti-haze mask disclosed by the invention has two important expansion functions: 1, in the case of fire alarm, wet tissues can be kept in the wet type anti-haze mask conveniently so as to resist dense smoke, so that two hands are released to move freely; therefore, the function of escaping is enhanced; and 2, in dusty construction sites, the wet type anti-haze mask is better than common masks in protection effect. The wet type anti-haze mask product is good in anti-haze effect, convenient to use and light.

Description

Wet type haze-proof mask

Technical field

The present invention relates to the technical measures that outdoor activity crowd protects at haze or sand dust weather human respiratory. Specifically adopt the protection of wet type mask. When adopting the protection of wet type mask, effect is better than dry mask, but must solve three big problems: 1 is that wet mask patch nozzle is worn uncomfortable; 2 is that respiratory resistance is big; 3 is need often moistening mask. For this, should be solved from Respirator structure.

Technical background

In recent years, owing to atmospheric pollution is serious, the air quality of China big and medium-sized cities becomes worse and worse. To outdoor activity crowd, it is huge, long-term to the actual bodily harm just caused at the teenager of going to school of growing especially. Proposition wet type mask of the present invention protection haze, the dust harm to human body, the huge Population Health for going to school, going to work provides effective and cheap protective equipment.

Summary of the invention

It is an object of the invention to design a kind of wet type haze-proof mask, it is intended to haze many dirt sky gas shielded outdoor activity crowd is not by the injury of bad air environment. Wet type haze-proof mask is mainly made up of wet mask, suction chamber, respiratory cavity, exhaustor and soft pack layer. When human body air-breathing, air pollution first flows through wet mask, adheres to through its multilamellar and crosses Lu, eliminates major part haze and dust enters suction chamber and sucks for human body through unidirectional orifice plate entrance respiratory cavity. Now also there is a small amount of air to suck from exhaust tube, but the relatively thin wet type that this partial air is above exhaust tube is crossed Lu layer and is also purified equally. As human exhaled breath, unidirectional orifice plate is closed, and air-flow can only be crossed Lu layer through relatively thin wet type and discharge from unidirectional exhaust tube. Cross Lu layer area ratio routine mask due to wet mask and wet type and want big, thus respiratory resistance is less. Due to air-flow directed flow, overcome thick mask and be detained the defect of exhalation gas. For preventing the too fast evaporation of moisture in wet mask, outside wet mask, it is provided with protective cover sunshade keeps out the wind. The periphery of wet type haze-proof mask is with nontoxic soft material Bao Gu, better with human body face laminating, it is prevented that air is directly entered nasal cavity without Lu. For preventing moisture on wet mask to be evaporated, user can carry with fog-spray nozzle and mineral water bottle, can squirt mask in time and conveniently. Wet mask is evaporated in short-term, still has certain protective capacities, will not use inefficacy.

Feature of the present invention:

1, compared with using common mask, wet type haze-proof mask protection effect is good. Common mask is too thin, although breathe unimpeded, but substantially unshielded effect; Although common mask is thicker certain protective capacities, but hypopnea. What more can't bear is that the foul smell stream breathed out is detained at each interlayer of mask, and the air-breathing making next time is second-rate, is unfavorable for healthy equally.

2, the wet type haze-proof mask of the present invention, have effect better, breathe more unobstructed, operation is very simple. It is good and cheap, popular protective device.

3, it has the expanded function that binomial is valuable: 1 is when there is fire alarm, as long as having worn wet type haze-proof mask and being within it further added by wet tissue etc., need not go to cover by a hands. Two handss can action voluntarily, greatly strengthen the escape ability of user. 2 is in the operation area stirred up a cloud of dust, and can provide ratio mask better effects if, cheap protective articles for workman.

Specific embodiments

In conjunction with accompanying drawing 1 and accompanying drawing 2, the present invention is described in further detail.

Referring to Fig. 1 and 2, wet type haze-proof mask is mainly made up of wet mask 6, framework 8, unidirectional exhaust tube 1 and soft pack layer 9. Being provided with suction chamber and respiratory cavity 5 in framework 8, framework 8 is climbed tightly by soft pack layer 9. Wet mask 6 is held at suction chamber anterior, and first the air that human body sucks adsorbs through wet mask 6 multilamellar and cross Lu becomes purification gas, enters respiratory cavity 5 then through by the half-duplex channel formed by counter direction jet trays 3 and the trap 4 started between respiratory cavity 5 and suction chamber. Now a small amount of air also can enter from unidirectional exhaust tube 1, but the relatively thin Lu layer that wet laid on its overhead arch form frame 2 is also purified. As human exhaled breath, the trap 4 that the hole on counter direction jet trays 3 is fallen covers, and foul smell stream can only be discharged from unidirectional exhaust tube 1, thus completing human body respiration to purify air circulation. The flap valve being now exposed at outside mask below unidirectional exhaust tube 1 is opened, and foul smell is discharged. It it is noted that the flap valve that at least should set two directions, it is prevented that outdoor haze air-flow withstands single flap valve, cause expiration not smooth. Owing to wet mask 6 air inlet area is relatively big, make air-breathing comparatively unobstructed. For preventing the too fast evaporation of moisture on wet mask 6, outside wet mask 6, it is provided with shutter 7 keeps out the wind for its sunshade. Soft pack layer 9 is made by nontoxic soft material, with human body face laminating better, it is prevented that dirty airflow directly leaks into respiratory cavity 5. Wet type haze-proof mask can conveniently take off humidification. When long period outdoor activities, can be with little fog-spray nozzle and mineral water at any time conveniently to shutter 7 internal spraying.

Claims
