[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-3 This utility model provides a PUVA therapy device for sunburn prevention, including a base 1, an operating part 2, and a phototherapy device body 3. The operating part 2 is located at the front of the base 1, and the phototherapy device body 3 is fixedly installed on the upper part of the base 1. A housing 4 is provided on the upper part of the phototherapy device body 3, a protective mechanism 5 is provided at the front of the housing 4, an adjustment mechanism 6 is provided inside the housing 4, and an ultraviolet lamp tube 7 is installed inside the housing 4 through the adjustment mechanism 6.

[0023] Further as Figure 2 and Figure 3 As shown, it is worth noting that the protective mechanism 5 includes a mounting groove 501, which is located on the front side of the housing 4. A mounting plate 502 is slidably installed in the mounting groove 501. A handle 503 is fixedly connected to the top of the mounting plate 502. A light-transmitting plate 504 is fixedly connected to the mounting plate 502. Limiting rods 505 are fixedly connected to the left and right surfaces of the mounting plate 502. The light-transmitting plate 504 has multiple light transmittances. The light-transmitting plate 504 is located in front of the ultraviolet lamp tube 7 through the mounting plate 502 and the mounting groove 501. The limiting rods 505 are made of elastic material.

[0024] In use, by replacing the light-transmitting plate 504 with different light transmittance, the light intensity of the ultraviolet lamp tube 7 can be adjusted according to the treatment needs, thereby improving the safety of treatment and avoiding skin damage to the treatment site. The setting of the limiting rod 505 can improve the stability of the mounting plate 502 in the mounting groove 501.

[0025] As can be seen from the above working process, when the phototherapy device 3 is used by the protective mechanism 5, it can change the light-transmitting plate 504 with different light transmittance according to the treatment needs to adjust the intensity of ultraviolet light in order to facilitate the treatment and reduce the damage of ultraviolet light to the skin.

[0026] Further as Figure 2 and Figure 3 As shown, it is worth noting that the adjustment mechanism 6 includes a mounting base 601, which is movably mounted inside the housing 4. Slider blocks 602 are fixedly connected to the upper and lower surfaces of the mounting base 601, respectively. Two sliders 602 are respectively provided at the upper and lower parts of the mounting base 601 and spaced apart. The mounting base 601 slides within the housing 4 via the sliders 602 and the sliding groove 603. The slider 602 has a corresponding sliding groove 603 on its inner surface of the housing 4, and a through groove 604 is provided inside the slider 602. A guide rod 605 is slidably disposed in the groove 604. The front end of the guide rod 605 is fixedly connected to the groove 603. A spring 606 is sleeved on the outside of the guide rod 605. The spring 606 is located at the front of the slider 602. A rotating seat 607 is fixedly connected to the rear surface of the mounting base 601. A threaded rod 608 is rotatably disposed in the rotating seat 607. A threaded sleeve 609 is threadedly connected to the threaded rod 608. The threaded sleeve 609 is fixedly connected to the rear of the housing 4. Reflector plates 6010 are fixedly connected to the left and right sides of the front of the mounting base 601.

[0027] In use, rotating the threaded rod 608 causes it to rotate within the threaded sleeve 609, thereby pushing the mounting base 601 to slide within the housing 4. The slider 602 and the groove 603 enhance the stability of the mounting base 601's sliding within the housing 4. The sliding of the mounting base 601, combined with the reflector 6010, improves the stability of ultraviolet light irradiation. Simultaneously, the sliding of the mounting base 601 compresses the spring 606. The spring force of the spring 606, when the threaded rod 608 is rotated, restores the mounting base 601 to its original position within the housing 4. Adjusting the position of the mounting base 601 allows for depth adjustment of the ultraviolet lamp 7, facilitating the use of the protective mechanism 5 to enhance the intensity of ultraviolet light irradiation and thus improving the device's practicality.

[0028] This solution has the following working process: When this device is used, treatment is performed through the ultraviolet lamp 7. By replacing the light-transmitting plate 504 with different light transmittance, the light intensity of the ultraviolet lamp 7 can be adjusted according to the treatment needs, thereby improving treatment safety and avoiding skin damage to the treatment site. The setting of the limiting rod 505 can improve the stability of the mounting plate 502 in the mounting groove 501. By rotating the threaded rod 608, the threaded rod 608 rotates within the threaded sleeve 609, thereby pushing the mounting base 601 to slide within the housing 4, and through the slider 60... The installation of the mounting base 601 and the sliding groove 603 improves the stability of the mounting base 601 sliding within the housing 4. The sliding of the mounting base 601, in conjunction with the reflector 6010, enhances the stability of ultraviolet light irradiation. Simultaneously, the sliding of the mounting base 601 compresses the spring 606. Through the elastic force of the spring 606, the mounting base 601 is restored to its original position within the housing 4 when the threaded rod 608 is rotated. By adjusting the position of the mounting base 601, the depth of the ultraviolet lamp tube 7 can be adjusted, thereby facilitating the use of the protective mechanism 5 to increase the intensity of ultraviolet light irradiation and thus improving the practicality of the device.

[0029] In summary: With the protective mechanism 5 in place, when the phototherapy device 3 is used, the light-transmitting plate 504 with different light transmittance can be replaced according to the treatment needs to adjust the ultraviolet intensity, thereby facilitating the treatment and reducing the damage of ultraviolet light to the skin. With the adjustment mechanism 6 in place, the position and depth of the ultraviolet lamp 7 can be adjusted according to the usage needs, which facilitates the adjustment of the ultraviolet irradiation intensity in conjunction with the protective mechanism 5, thereby improving the practicality of the device.
