The mode further effectively reduces the spread of the novel coronavirus in the protective cover to the outside.

Of course, the novel coronavirus resistant glove additionally arranged on the second cover body also has other convenient operations.

Example 6:

the principle of the disinfectant for killing the novel coronavirus is as follows: the novel coronavirus is a novel RNA coronavirus with an envelope, the heat resistance is poor, and the outer envelope is sensitive to organic solvents and disinfectants. Once the envelope is destroyed by the disinfectant, RNA is also very easily degraded (for example, hypochlorous acid generated by sodium hypochlorite in 84 disinfectant in aqueous solution can decompose nascent oxygen, has strong oxidizing property, and can oxidize nucleic acid substances of the novel coronavirus), thereby inactivating the novel coronavirus.

As shown in fig. 1, 3, 4, 12, 13, 14, the arch body 1 is provided with a coupling hole 13 at the center of the arch, and the exhaust device 200 is flange-coupled to the coupling hole 13 of the arch body.

The working principle of the disinfectant sterilizing device provided by the invention is as follows: the disinfectant barrel 203 is filled with a proper amount of disinfectant, the disinfectant barrel cover is covered, the second air guide pipe 204 is fixed, and the air outlet of the second air guide pipe 204 is arranged below the liquid level of the disinfectant [ the air outlet of the second air guide pipe 204 is arranged below the liquid level of the disinfectant and close to the inner bottom surface of the disinfectant barrel 203 ].

In the present invention, the air pump 202 is a unidirectional air pump, and the air pumping direction thereof can only be outputted from the first air guiding pipe 201 to the second air guiding pipe 204 through the air pump 202.

The air pump 202 can be designed into a plurality of air-shift circuits, and medical staff can adjust to a proper gear according to actual requirements. After the air pump 202 is operated, the air in the mask main body 100 passes through the first air guiding pipe 201, the air pump 202 and the second air guiding pipe 204, and finally enters the disinfectant barrel 203. The new coronavirus in the mask body 100 enters the sterilizing liquid along with the air and is sterilized by the sterilizing liquid. The invention connects the air draft system with the disinfectant barrel containing the novel coronavirus disinfectant capable of killing the new corona to filter, thereby avoiding the pollution of the pumped air to the surrounding environment.

The air outlet of the disinfectant barrel 203 is provided with a filtering part, the filtering part can use an exhaust filtering structure (such as an N95 mask) similar to a novel coronavirus preventing mask, and the filtering part designed at the position can stop novel inactivated coronavirus in the disinfectant barrel 203. If the novel coronavirus which is not killed needs to be treated, the air outlet is sealed, the disinfectant barrel 203 is inverted, and the novel coronavirus can be killed on the inner surface of the filtering part and the wall surface of the upper part of the disinfectant barrel 203.

The air exhaust device 200 arranged in the invention exhausts the air in the cover main body to be below the liquid level of the disinfectant in the disinfectant barrel through the operation of the air exhaust pump, and the design can accelerate the air circulation in the cover main body and further reduce the transmission of novel coronavirus in the cover main body to the outside.

Example 7:

the disinfectant sterilizing device can be replaced by a heatable sterilizing device, the replacing part is a disinfectant barrel 203, the disinfectant barrel 203 is replaced by an electric kettle type heating structure, and the air inlet end of the electric kettle type heating structure is connected with an air exhaust device 200. The container of the electric kettle type heating structure is filled with water, and the heating part heats the water to more than 56 ℃.

Since the novel coronavirus was able to be killed at a temperature above 56 ℃ and heated for at least 30 minutes [ the higher the temperature, the shorter the time the novel coronavirus survived ].

Firstly, the electric kettle type heating structure heats the water in the electric kettle type heating structure to more than 56 ℃ and continuously heats the water, then, the air outlet end of the second air guide pipe 204 enters the water surface, the air suction pump 202 is started, the novel coronavirus enters the water body, the water temperature of more than 56 ℃ is kept to continuously kill the novel coronavirus (the higher the temperature is, the shorter the survival time of the novel coronavirus).

Install the filter house at the air outlet of electric kettle, the similar carminative filtration that can prevent that novel coronavirus gauze mask is similar can be used to the filter house [ like N95 gauze mask ], and the filter house of design here can make the novel coronavirus that does not kill stop inside the electric kettle, because last high temperature in the electric kettle, the novel coronavirus that is stopped can be killed along with the time.

The design of example 7 is to accelerate the air circulation within the mask body and to further reduce the transmission of new coronaviruses to the exterior within the mask body.

In summary, the cover body of the device of the present invention is provided with a plurality of partial windows, so that the medical staff can open the protective cover to examine or operate the patient, and after the operation is completed, the protective cover covers the open holes.
