A liquid carrier respirator

Abstract

The invention discloses a liquid carrying breather which is specially used for person preventing atmospheric pollution. The liquid carrying breather comprises a filtering box, a breath cover, a liquid storage box and a waste liquid recovery device, the liquid storage box is arranged beside the filtering box, a liquid filling port is formed in the top of the liquid storage box, a plurality of liquid filling valves are distributed on the liquid storage box from top to bottom, each liquid filling valve is individually controlled, and liquid in the liquid storage box can be filled into a liquid gas cavity by controlling the liquid filling valves. The liquid carrying breather has the advantages that the liquid carrying breather is small in integrated size and light in weight, liquid amount opening three liquid filling valves sufficiently prolongs 60-minute use time of the filtering box and sufficiently used by a user for daily preventing atmospheric pollution, liquid can be conveniently supplemented toward the liquid filling port when the liquid storage box is exhausted, so that the liquid storage box continues to be used, design of the liquid gas cavity is improved, liquid exists in the liquid gas cavity no matter the user lowers the head or raises the head, and the method solve the problem that gas is directly breathed by the user without being dissolved by liquid.

Description

technical field [0001] The present invention relates to a kind of respirator, more specifically, relate to the fourth-generation liquid-carrying respirator specially used for personal air pollution prevention. Background technique [0002] There are many types of existing dust masks, which can prevent dust and smoke from being sucked into the human body in some harsh environments, such as sandstorms and smoke. However, when the filtering effect is good, this filtering structure , Most of the air circulation is not smooth, which will make the user feel difficult to breathe, and when the breathing is smooth, the filtering effect will be greatly reduced, which is very inconvenient to use. Moreover, according to the National Measurement and Control Network, "the current technology is temporarily unable to wear a mask. There is no scientific basis for anti-pm2.5, and even the N95 mask with the highest standard has not achieved this effect”; I applied for a Chinese utility model p...

Problems solved by technology

[0002] There are many types of existing dust masks, which can prevent dust and smoke from being sucked into the human body in some harsh environments, such as sandstorms and smoke. However, when the filtering effect is good, this filtering structure , Most of the air circulation is not smooth, which will make the user feel difficult to breathe, and when the breathing is smooth, the filtering effect will be greatly reduced, which is very inconvenient to use. Moreover, according to the National Measurement and Control Network, "the current technology is temporarily unable to wear a mask. There is no scientific basis for anti-pm2.5, and even the N95 mask with the highest standard has not achieved this effect”; I applied for a Chinese utility model patent number 200520054411. Invention Patent No. 200910214111.1, named the third-generation liquid-carrying respirator, solves the above problems, but the above two patents also have obvious shortcomings

[0003] No. 200520054411.5, titled as a utility model of a new type of liquid-carrying respirator. The disadvantage of the disclosed technical solution is that there is no waste liquid recovery device, and when the user exhales, the excess liquid will wet people's clothes when discharged Second, there is no liquid-air channel in the filter box. When the liquid level is relatively low or the user's head shakes, the air entering from the air inlet will be directly breathed by the user without being dissolved by the liquid.

[0004] No. 200910214111.1, the shortcoming of the disclosed technical scheme of the third-generation liquid-carrying respirator invention patent is that the first is that the volume of the liquid storage tank is relatively large, so that the weight of the whole set of equipment is about 1200 grams, and the weight is relatively large. It is easy to cause discomfort after use, and it is not suitable for personal daily air pollution prevention. The second is that the liquid-gas channel is unreasonably set up. It only has a vertical partition to separate the filter box into a filter chamber and a liquid-gas chamber. The connection between the two The position is located under the vertical partition. When the person bows his head, the liquid will concentrate in the lower right corner of the filter cavity. When the liquid level is low, the liquid cannot cover the connection port, so the air entering from the air inlet is directly breathed by the user without being dissolved by the liquid. The third is that the waste liquid recovery device consists of a hose and a container, which is too bulky and inconvenient to carry
