And one-way valves are arranged at the positions of the air inflow and outflow of the air outlet 8, the air outflow inlet 9, the air inflow inlet 12 and the air outflow outlet 13, so that the air flows in and out in the cavity of the shell 11 according to a specified path. The air suction channel and the air expiration channel are separated by the air passage partition plate 10, and are filtered by the filter body 4 (such as filter cotton which adopts standard filtering materials above N95), the inner wall of the cavity of the shell 11 is coated with an ultraviolet reflecting layer, the ultraviolet luminous body 5 (such as an ultraviolet lamp tube) and the forced ventilation structure 2 (such as a fan or an air pump) are arranged in the cavity of the shell 11, the ultraviolet luminous body 5 (such as the ultraviolet lamp tube) is fixed by the supporting body 3, and the filter body 4 (such as the filter cotton) surrounds the ultraviolet luminous body 5 (such as the ultraviolet lamp tube), so that the filter body 4 (such as the filter cotton) can be irradiated in all directions. When the air purifier is used, when external air enters the area of the air suction air outlet 8 from the air suction air inlet 12, because viruses and bacteria blocked by the filter body 4 (such as filter cotton) are blocked at one side close to the ultraviolet luminous body 5 (such as an ultraviolet lamp tube), namely the inner side of the filter body 4 (such as filter cotton), the ultraviolet luminous body 5 (such as an ultraviolet lamp tube) has the function of killing the viruses and the bacteria, the viruses and the bacteria at the inner side of the filter body 4 (such as filter cotton) can be killed in a short time, and the viruses and the bacteria at the outer side of the filter body 4 (such as filter cotton) can be killed due to the transmission effect of ultraviolet rays and the reflection coating of the inner wall of the cavity of the shell 11. The air outlet 8 outputs filtered air for human body due to positive wind pressure of the forced ventilation structure 2 (such as a fan or an air pump), and the air with higher temperature and moisture exhaled by human body is discharged into the area of the air inlet 9 due to positive wind pressure, so as to ensure that the temperature of the air in the air outlet 8 is not affected by the exhaled air of human body. If the human body exhaled air carries viruses and bacteria, the viruses and the bacteria are blocked by the filter body 4 (such as filter cotton) and are killed based on the same principle. The ultraviolet luminous body 5 (such as an ultraviolet lamp tube) and the forced ventilation structure 2 (such as a fan or an air pump) are normally opened when being electrified, the heat of the ultraviolet luminous body 5 (such as the ultraviolet lamp tube) and the rapid airflow generated by the forced ventilation structure 2 (such as the fan or the air pump) are utilized to ensure that the airflow and the filter body 4 (such as filter cotton) are dry, simultaneously, the airflow, the virus and bacteria in the ultraviolet irradiation range of the inner wall of the cavity of the shell 11, the filter body 4 (such as the filter cotton) and the forced ventilation structure 2 (such as the fan or the air pump) and the like are killed, the breathing safety of a human body is ensured, and finally, the clean gas exhaled by the human body is exhausted from the exhalation. The whole protection device does not transmit ultraviolet rays outwards, and ultraviolet rays do not leak when gas enters and exits. This protector places battery 6 for the rational utilization space in the gas outlet 8 of breathing in, exhale air inlet 9 both sides, easily later stage change.

To sum up, the utility model discloses a protector has following advantage: 1. all accessories and materials can be put into an ultraviolet charging disinfection cabinet for disinfection, a forced ventilation structure (such as a fan) rotates reversely during charging, viruses and bacteria killed in the cavity of the shell are discharged and enter the disinfection cabinet, and the device is not influenced when being repeatedly used; 2. the forced ventilation structure (such as a fan) enables air flow to keep the flow direction of an air suction inlet, an air suction outlet pipeline, an air suction outlet, an air expiration inlet and an air expiration outlet, wherein dust, viruses and bacteria are blocked by a filter body (such as filter cotton) with the grade above N95, and an ultraviolet light emitting body (such as an ultraviolet light tube) can kill the viruses and bacteria blocked in the surface, the air suction channel and the air expiration channel area by the filter body (such as the filter cotton) in a two-way mode; 3. during the use process, substances such as dust, viruses, bacteria and the like are adsorbed on the surface of the filter body (such as filter cotton), so that the electrostatic adsorption effect is relatively weakened, the forced ventilation structure (such as a fan) is normally opened to enable airflow to rapidly pass through the filter body (such as filter cotton) and rub with fibers on the filter body (such as filter cotton) to generate static electricity, the static electricity quantity and the adsorption effect of the filter body (such as filter cotton) are kept, and the replacement period of the filter body (such as filter cotton) is delayed; 4. the separation of the inspiration channel and the expiration channel can reduce the problems of sultriness and suffocation caused by temperature rise when the human body exhales; 5. the moisture exhaled by the human body in the shell cavity is evaporated out of the shell cavity through the exhalation air outlet by the heat emitted by the ultraviolet luminous body (such as an ultraviolet lamp tube); 6. the gear controller arranged in the circuit board 7 can provide comfortable air flow for human body breathing by controlling a forced ventilation structure (such as a fan); 7. in order to prevent the respiratory gas of the human body from being polluted, one-way ventilation structures (such as one-way valves) which are convenient to assemble and disassemble are arranged at the air suction inlet, the air suction outlet, the air expiration inlet and the air expiration outlet, and the flow direction of the air flow from the air suction inlet, the air suction outlet, the air expiration inlet and the air expiration outlet is kept; 8. the outermost ends of the air suction inlet, the air suction outlet, the air expiration inlet and the air expiration outlet are also provided with ultraviolet shielding structures, so that ultraviolet rays are prevented from leaking outside the device or directly irradiating the face or the nasal cavity of a person.
