DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will be further described below through embodiments in conjunction with the accompanying drawings.

[0024] Refer to Figures 1 to 5, a UVC-LED lamp sterilization module, comprising a mounting base 1 and a sterilization lamp assembly. A rotating motor 2 is provided on the mounting base 1. A rotating seat 3 is provided at the movable end of the rotating motor 2. A movable tube 4 is provided on the rotating seat 3. A plurality of mounting plates 401 are arranged on the outer wall of the movable tube 4 in an annular array. A plurality of UCV-LED beads 402 are arranged on the mounting plates 401 in the height direction. The UVC-LED beads are ultraviolet light-emitting diodes that emit ultraviolet light in the UVC band, and the wavelength is usually between 200 and 280 nanometers, which is prior art and will not be elaborated here.

[0025] The sterilization lamp assembly includes a base 5, a light-transmitting cover 6, and a water level tube 7. The base 5 is of an annular structure. An installation ring 501 is integrally formed on the upper part of the base 5. The inner wall of the first end of the light-transmitting cover 6 is threadedly connected to the outer wall of the installation ring 501, so that the first end of the light-transmitting cover 6 is sleeved on the outer ring wall of the base 5 and is detachably connected. Preferably, a sealing ring 8 is sleeved on the installation ring 501, and the sealing ring 8 abuts against the opposite sides of the base 5 and the light-transmitting cover 6 respectively, for improving the sealing performance between the base 5 and the light-transmitting cover 6.

[0026] The inner wall of the installation ring 501 cooperates with the inner wall of the base 5. The water level tube 7 is sleeved on the inner wall of the base 5, so that an activity space is formed between the light-transmitting cover 6 and the water level tube 7. The outer diameter of the water level tube 7 is smaller than the inner diameter of the movable tube 4. A first connection ring 101 is provided on the mounting base 1. A first installation groove 601 is formed on the outer wall of the second end of the light-transmitting cover 6. The first connection ring 101 is threadedly connected to the first installation groove 601, so that the second end of the light-transmitting cover 6 is detachably connected to the mounting base 1. When the mounting base 1 and the light-transmitting cover 6 are assembled, the movable tube 4 is inserted into the activity space. The connection between the mounting base 1 and the light-transmitting cover 6 is used to enclose the activity space and make the movable tube 4 located in the activity space. An annular groove 502 is formed by concave molding on the end face of the installation ring 501 close to the activity space. A guiding portion 403 that is slidably connected in the annular groove 502 is provided at the first end of the light-transmitting cover 6, for positioning the position of the movable tube 4 in the activity space and guiding the rotation of the movable tube 4 in the activity space.

[0027] A second installation groove 503 is formed on the inner wall of the base 5. A second connection ring 701 is provided on the outer wall of the water level tube 7. The second connection ring 701 is threadedly connected to the second installation groove 503, so that the water level tube 7 is detachably connected to the base 5. After the water level tube 7 and the base 5 are assembled, the bottom surface of the base 5 is matched with the end face of the second connection ring 701.

[0028] When the sterilization module is in use, the base 5 extends into the water body and is supported on the inner bottom surface of the water tank 12. The rotating motor 2 drives the rotating seat 3 to rotate, driving the movable pipe 4 to rotate around the axis of the water level pipe 7. Each UCV-LED lamp bead 402 on the mounting plate 401 rotates. The movable pipe 4 rotating in the movable space does not affect the water body in the water tank 12. The ultraviolet rays emitted by each UCV-LED lamp bead 402 pass through the light-transmitting cover 6 and irradiate outward into the water body in the water tank 12, enabling the sterilization module to irradiate the water body in the water tank 12 more evenly, thereby sterilizing the static water body more comprehensively and improving the sterilization efficiency.

[0029] The rotating seat 3 is located inside the light-transmitting cover 6. A controller 9 is arranged on the rotating seat 3. Each UCV-LED lamp bead 402 and the rotating motor 2 are electrically connected to the controller 9 and controlled by it. A clearance fit is formed between the rotating seat 3 and the water level pipe 7 to prevent collision between the water level pipe 7 and the controller 9.

[0030] Three supporting parts 504 distributed in an annular array are arranged at the bottom edge of the base 5. The gap between two adjacent supporting parts 504 is communicated with the inner wall of the water level pipe 7. The water body enters the inner wall of the water level pipe 7 through the gap between two adjacent supporting parts 504. According to the principle of communicating vessels, when the water body in the water tank 12 is static, the liquid level of the water body in the water level pipe 7 is kept flush with the liquid level of the water body in the water tank 12. An induction switch 10 electrically connected to the controller 9 is arranged at the top of the water level pipe 7. A floating body 11 is slidably connected to the inner wall of the water level pipe 7. Positioning parts 1102 are symmetrically arranged on the floating body 11. Positioning grooves 702 for slidably connecting the positioning parts 1102 are formed on the inner wall of the water level pipe 7. The water body in the water level pipe 7 drives the floating body 11 to float. An induction part 1101 for inductively cooperating with the induction switch 10 is arranged on the floating body 11. Preferably, the induction switch 10 can be a metal sensor, and the induction part 1101 can be a thin-sheet-shaped induction metal. When the induction part 1101 rises to a position corresponding to the induction switch 10, the induction end of the induction switch 10 inductively cooperates with the induction part 1101, and the induction switch 10 triggers a signal, causing the controller 9 to control each UCV-LED lamp bead 402 and the rotating motor 2 to start. The setting of the induction switch 10 ensures that the sterilization module is automatically started for sterilization operation after the water tank 12 is filled with water, preventing each UCV-LED lamp bead 402 from operating at full load when the water body in the water tank 12 is not filled, resulting in energy waste.

[0031] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
