Third-generation liquid-carrying breather

Abstract

The invention relates to a liquid-carrying breather which comprises a filter tank and a breathing mask, wherein the filter tank comprises a filter cavity and a liquid-gas cavity, and the bottoms of the filter cavity and the liquid-gas cavity are communicated through liquid; the upper part of the filter cavity is provided with an air outlet; the upper part of the liquid-gas cavity is respectively provided with a liquid inlet and an air inlet; and an air sucking valve and an air exhaust valve which are connected with the air outlet are arranged on the breathing mask. The liquid-carrying breather also comprises a waste liquid recovery device connected with the air exhaust valve and a portable liquid tank connected with a liquid inlet hole of the liquid-gas cavity, and a liquid control device is also arranged between the liquid-gas cavity and the portable liquid tank. In the liquid-carrying breather, the portable liquid tank is used as a container for storing liquid, thus the liquid storage quantity is large, the service time is long, and the waste water recovery package is equipped. The liquid-carrying breather is suitable for various complicated occasions and has good dustproof effect; meanwhile, the filter tank has small volume and simple processing.

Description

technical field [0001] The present invention relates to a respirator, in particular to a liquid-carrying respirator. 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, and it is very inconvenient to use; thus there has been a liquid-carrying respirator, which uses water to achieve air purification. The filtration, the patent 200520054411.5 that I applied for a new type of liquid-carrying respirator has just solved the above-mentioned problem, and it comprises respirator and is respectively arranged on the filter box of respirator both sides, and the structure of filter box is as foll...

[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, and it is very inconvenient to use; thus there has been a liquid-carrying respirator, which uses water to achieve air purification. The filtration, the patent 200520054411.5 that I applied for a new type of liquid-carrying respirator has just solved the above-mentioned problem, and it comprises respirator and is respectively arranged on the filter box of respirator both sides, and the structure of filter box is as follows Image 6 As shown, there are intercommunicating cavities 2 which communicate with the inner cavity of the breathing mask. A filter plate 3 with a mesh is placed in the cavity 2. A water storage tank 5 is provided on one side of the filter box 1. The water storage tank 5 The water control valve 4 and the filter box 1 are in water communication with each other, and the top of the filter box is provided with an air inlet 6, and the air inlet 6 is connected with the cavity of the filter box that is in water communication with the water control valve 4

[0003] Wherein, the capacity of the water storage tank 5 that is arranged on one side of the filter box 1 is very small, if used in the environment with larger pollution or smoke, the water in the filter box is very easily polluted and needs to be replaced frequently, and this The small water storage capacity of the water storage tank and the need for external replenishment water sources are inconvenient and shorten the use time of the respirator

[0004] In addition, in order to prevent the water in the filter box from flowing back into the breathing mask when inhaling, there is a curved groove 7 on the top of the filter box, which also makes the volume of the whole filter box relatively large, and it is quite inconvenient to process and assemble ; Simultaneously, when using in the environment with bigger wind and sand, there are more thick and heavy sand and dust that walk in the strong wind, and the air inlet 6 of filter box is not provided with any barrier, and sand and dust may enter and be deposited in the bottom of filter box, Therefore, frequent maintenance and cleaning are required, causing inconvenience to use

In addition, because the respirator is a structure that fits closely with the human face, the moisture contained in the gas exhaled or inhaled by the person condenses on the inner wall of the respirator and is discharged. When wearing the respirator, in order to prevent water droplets from dripping everywhere, The user should also pay great attention during wearing and using, which will also cause inconvenience to the user
