Description

Health safety protection mask

Technical Field

The utility model relates to a gauze mask, concretely relates to health safety protection gauze mask.

Background

Most of the masks on the market at present improve the sealing performance for better cold protection, heat preservation, dust resistance and bacteria prevention, but not only reduce the ventilation performance of the masks, but also increase the breathing resistance. Moreover, these masks all have only a cavity to cause expired gas and inhale gaseous mixing, let the person of wearing when breathing greatly reduced the oxygen inspiration volume, not only reduced the comfort level, still influenced health. If the wearer himself suffers from some bacterial or viral respiratory diseases, the wearer needs to be treated, and even repeatedly infects the wearer if wearing the mask, so that the recovery is affected. Therefore, doctors believe that respiratory disease patients, respiratory sensitive people, heart disease patients, hypertension patients, pregnant women and other special people are not suitable for wearing the mask, and even ordinary healthy people are not suitable for wearing the mask during exercise. Some breathing masks with breathing valves are invented, and although the breathing resistance is reduced compared with the common masks, the breathing mask does not fundamentally improve the mixing of breathing gas and inspiratory gas, is inconvenient to clean and is not suitable for being used repeatedly.

The patent document with the Chinese application number of 201510586552.X and the publication number of 2015.12.9 discloses a convenient breathing mask, which comprises a mask body, wherein a left ear rope sleeve and a right ear rope sleeve are fixed on two sides of the mask body, an inner cup is arranged on the inner side of the mask body, filter cotton is arranged in the inner cup, an exhaust pipe is connected with the filter cotton, a fixing nut is arranged on the exhaust pipe and fixed at the center of the mask body, the exhaust pipe extends out of the mask body, and an exhaust pipe is arranged at the outer end of the exhaust pipe

The hole, the blast pipe embeds has discharge valve, installs the air discharge valve on the discharge valve, and one side of inner cup is fixed with the one end of intake pipe, installation admission valve in the intake pipe bottom, and the outer end of intake pipe stretches out the outside of the gauze mask body, and the outer port of intake pipe is built-in to have active carbon. The air inlet valve is a one-way valve which can only inlet but not outlet, and the exhaust valve is a one-way valve which can only outlet but not inlet.

When the breathing mask is used for exhausting, the air can reach the exhaust valve to be exhausted through the filter cotton and the exhaust pipe, and the distance between the exhaust valve and the inner cover cup is long; the stay time of the discharged gas in the exhaust pipe is long, so that the discharged gas is easy to store in the exhaust pipe; meanwhile, the air inlet pipe of the mask is communicated with the exhaust pipe, so that gas which stays in the exhaust pipe and is not discharged in time can be sucked into a human body during air suction; carbon dioxide is inhaled during inspiration, so that less oxygen is inhaled during inspiration, and further discomfort is caused to a human body; meanwhile, the mask is only provided with one air inlet pipe, so that the inhaled oxygen is effective during air suction; the use scene of this gauze mask receives the restriction like this, can lead to breathing not smooth and easy when carrying out physical labor when wearing this gauze mask.

In addition, the air outlet of the existing mask is basically in a straight-line type, so that spray and the like generated by human body exhalation easily enter the air, and are unhealthy for other people.
