This application includes an ultraviolet light therapy device body and a supporting plate arranged on the ultraviolet light therapy device body, a mounting block is fixedly connected to the supporting plate, a lamp holder is fixedly connected to the mounting block, a plurality of ultraviolet lamp tubes are arranged on the lamp holder, a protective component for preventing ultraviolet rays from shining on the patient's eyes is arranged on the supporting plate, and a placement box with an anti-ultraviolet eye mask is arranged on the ultraviolet light therapy device body. The utility model can block ultraviolet rays to prevent ultraviolet rays from shining on the patient's eyes and causing harm to the patient.

[0004] Although the ultraviolet light therapy device in the above technology can block the ultraviolet light on one side through the baffle during use to prevent the ultraviolet light from irradiating the patient's eyes, the ultraviolet light will still irradiate into the environment in other directions during the patient's treatment, causing certain harm to the surrounding medical staff.

[0018] 2. The present invention can effectively filter the dust in the air flowing inside the air guide frame through the setting of the air filter, effectively improve the cleanliness of the air delivered by the air supply fan, and avoid the dust in the environment from polluting the internal environment of the protective cover. Through the setting of the push plate, the fixed rod and the cleaning brush, when the water flows through the guide box, the push plate can move downward under the push of the water pressure. The movement of the push plate can drive the fixed rod and the cleaning brush to move, so that the cleaning brush can clean the dust attached to the right side of the air filter, thereby achieving the effect of cleaning the surface of the air filter, effectively avoiding the air filter from being blocked, and ensuring that the air filtering work can be carried out for a long time and stably. Through the setting of the fourth rubber ring, the sealing of the contact between the push plate and the guide box is effectively improved.

The provision of the guide vertical rod achieves the purpose of guiding the moving rod. The purpose of the horizontal plate for guiding is to prevent the horizontal plate from tilting during the movement. The inclined air holes are set so that the air inside the protective cover can be discharged to the outside.

[0040] The working principle of the present invention is as follows: first, after the patient to be treated lies flat on the top of the treatment bed, the protective cover 7 is moved as a whole so that it is above the patient's desired treatment area, and then the drive motor 27 is started to drive the adjusting screw 29 and the L-shaped rotating rod 31 to rotate along the bearing on the working box 4. The rotation of the L-shaped rotating rod 31 can drive the moving rod 33 and the second piston 41 to reciprocate horizontally along the inner cavity of the conveying cylinder 34 through the connecting plate 32. Under the action of the movement of the second piston 41, the water inside the box body 1 can be extracted through the conveying cylinder 34 and the first one-way valve 35, and at the same time, it can be transported to the inside of the water collecting box 3 through the second one-way valve 36, the guide box 12 and the pipeline, thereby achieving the purpose of cleaning the inside of the water collecting box 3. The effect of water storage is achieved, and the horizontal plate 5 can be driven to move downward under the action of the rotation of the adjusting screw 29. The movement of the horizontal plate 5 can drive the pressurizing cylinder 10, the first piston 15, the vertical rod 17 and the protective cover 7 to move downward, so that the protective cover 7 can contact the top of the treatment bed and shield the area to be treated by the patient. Under the action of the ultraviolet lamp 21, the area to be treated by the patient can be irradiated with ultraviolet light, thereby achieving the effect of effective ultraviolet light therapy for the patient. At the same time, under the action of the continuous movement of the horizontal plate 5 and the pressurizing cylinder 10, the first piston 15 can compress the air inside the pressurizing cylinder 10, so that the air can be continuously input into the interior of the protective airbag strip 19 through the pipeline, and the protective airbag strip 19 can expand The sponge baffle 18 is driven to block the gap between the protective cover 7 and the patient's skin, effectively reducing the light pollution caused by the diffusion of ultraviolet rays to the outside during the patient's treatment, thereby improving the overall safety of use. In addition, under the action of the pressure increase caused by the compression of the air inside the pressurized cylinder 10, the baffle plate 25 can move upward under the action of the pressure push, and the movement of the baffle plate 25 can drive the magnetic block 26 to move, so that the magnetic block 26 can contact the magnetic control switch 22 inside the fixed cylinder 14 under the action of the movement, and the contact inside the magnetic control switch 22 can be closed under the action of the magnetic force of the magnetic block 26, so that the supply fan 42 can work, and the supply fan 42 can drive the outside air to pass through the air guide frame 13, the box body 1 and the air guide The hose 9 transports air to the inside of the protective cover 7, and the transported flowing air can carry away the heat generated by the ultraviolet lamp 21 inside the protective cover 7 when it is working, effectively preventing the patient's skin from being burned due to the high temperature inside the protective cover 7 during treatment. At the same time, through the setting of the humidity sensor 20, the humidity inside the protective cover 7 can be monitored, and when the value monitored by the humidity sensor 20 is lower than the preset value of the humidity controller 8, the humidity controller 8 will control the solenoid valve 38 to open accordingly. Under the action of the opening of the solenoid valve 38, the water contained in the water collecting box 3 and located above the water guide baffle 39 can flow to the bottom of the inner cavity of the water collecting box 3, and sprinkle along the surface of the water sprinkling hole 37 to the bottom of the inner cavity of the box body 1.Under the effect of the falling water, the air delivered by the air supply fan 42 can be effectively humidified and the environment inside the protective cover 7 can be effectively humidified and regulated, so as to avoid the environment inside the protective cover 7 causing discomfort to the patient's skin due to dryness, thus meeting the patient's use needs to a great extent.
