[0025] The heat dissipation device 3 includes a heat dissipation block 31, a heat dissipation fin 32 and a heat dissipation pipe 33, wherein the heat dissipation block 31 is arranged behind the ultraviolet lamp board 14, and the two are attached to each other. When working, the heat generated by the ultraviolet lamp board 14 can be directly conducted to the heat dissipation block 31, and multiple heat dissipation fins 32 are evenly arranged in parallel behind the heat dissipation block 31. Multiple heat dissipation pipes 33 are evenly distributed on the heat dissipation block 31. The heat dissipation pipe 33 in this embodiment is a horizontal U-shaped arrangement, and the bottom of the U-shaped is embedded in the corresponding groove on the heat dissipation block 31. The two horizontal ends of the U-shaped are parallel to each other and both penetrate There are multiple parallel heat sinks 32, and the heat sinks 32 are all connected in series on the heat pipes 33. The heat on the ultraviolet lamp board 14 absorbed by the heat sink 31 can be quickly conducted out through the heat pipes 33 and transferred to the heat sink 32. The heat sink 33 in this embodiment is made of copper tubes, and is filled with heat-conducting fluid inside. The heat-conducting fluid accelerates the heat conduction rate of the heat sink 33, and can more conveniently and quickly absorb and dissipate the heat transferred on the heat sink 33. Corresponding fans 3 are respectively installed on the left and right sides of the heat sink 32. 4 and an air guide plate 35. In this embodiment, the fan 34 is arranged on the left side of the heat sink 32, and the air guide plate 35 is arranged on the right side of the heat sink 32.

When working, the hand-held part 2 is the handle of the therapeutic device, which is convenient for the user to grasp and use. The hand-held part 2 includes a handle shell 21, and the handle shell 21 is a shell with a hollow interior and an open upper end. The upper end of the handle shell 21 is connected to the side wall of the head shell 11 below the head shell 11 near its rear end position, and the connection between the two is connected by a smooth curve, which is convenient for grasping during use. A power switch 22 and a start-stop switch 23 are provided on the side wall of the handle shell 21, and both are arranged at the upper end of the side wall of the handle shell 21, wherein the power switch 22 is arranged at the upper end of the side wall of the handle shell 21 corresponding to the bottom of the control panel 4, and the start-stop switch 23 is arranged at the upper end of the side wall of the handle shell 21 corresponding to the bottom of the control panel 4, and the start-stop switch 23 is arranged at the upper end of the side wall of the handle shell 21 corresponding to the bottom of the control panel 4. The power switch 22 is located at the upper end of the side wall of the handle shell 21 on the other side.

Through this interface, the therapeutic device can be directly connected to a power source for charging.
[0029] In this embodiment, the therapeutic apparatus adopts a boost constant current technology, and a low voltage input can drive the LED lamp 16 to emit high-intensity ultraviolet rays with a peak value of 308nm±3nm.
[0030] When in use, the ultraviolet therapeutic device of the utility model which is easy to dissipate heat can either add batteries into its battery slot 24, or directly connect to an external power source through its power interface 26. After the power is connected, turn on its power switch 22. At this time, the treatment time and light intensity can be set according to the treatment needs through the control panel 4. After setting, the treatment work can be started. Grasp the handle of the therapeutic device with your hand, aim the light outlet 12 at the part to be treated, press the start-stop switch 23, the ultraviolet lamp panel 14 can start working, and the LED lamp 16 starts to emit ultraviolet light according to the setting, and starts to treat the treatment part. If it is necessary to pause during the treatment process, it can be controlled to pause or start again by repeatedly pressing the start-stop switch 23. When When the set treatment program is completed, the treatment device will automatically stop, and the treatment is completed. If a second treatment is needed, the treatment program can be reset through the control panel 4 and the above treatment process can be repeated. If no treatment is needed, press the power switch 22 to turn off the treatment device. When the power switch 22 is turned on, the heat dissipation device 3 starts to work, and the hot air of the heat dissipation device 3 is discharged from the treatment device through the ventilation holes 15 on the right side under the action of the fan 34. At the same time, the cold air enters the inner cavity of the head shell 11 through the ventilation holes 15 on the left side of the head 1 and reaches the heat dissipation device 3. The cold air absorbs the heat of the heat dissipation device 3 and becomes hot air, which is then discharged from the head shell 11. This reciprocating process is repeated to achieve the purpose of continuous heat dissipation.
[0031] The heat dissipation of the ultraviolet therapeutic device 3 is better than that of the conventional therapeutic device. The light outlet 12 of the ultraviolet therapeutic device 3 is larger, and the treatment area is larger. The application of the heat dissipation pipe 33 in the ultraviolet therapeutic device 3 is better, and the speed at which the heat dissipation device 3 transfers the heat from the ultraviolet lamp board 14 is improved. The heat is transferred to the heat sink 32, and the cold air is taken in from one side of the fan 34 to take the heat of the heat sink 32 away from the other side. This not only reduces the probability of repeated hot air entering the heat sink 3, but also improves the heat dissipation rate of the heat sink 32, so that the heat dissipation effect is better, and the heat dissipation rate and efficiency of the heat dissipation device 3 are improved. The use of the wind guide plate 35 reduces the air resistance and noise during air flow, and reduces the contradiction between heat dissipation and noise. As mentioned above, the ultraviolet therapeutic device 3 is better in heat dissipation effect, and the ultraviolet light intensity it can emit is higher. When the intensity is high, the maintenance time will be more stable and longer.
