[0038] Example 1

[0039] Reference Figure 1 , Figure 2 The first embodiment of this utility model proposes an automatic cleaning ultraviolet sterilizer 100.

[0040] In this embodiment of the utility model, the automatic cleaning ultraviolet sterilizer 100 includes: a housing 1, with a sterilization chamber 12 inside the housing 1; a cover 2, rotatably connected to the housing 1; a protective cover 3, disposed on the cover 2 and located inside the sterilization chamber 12, with an ultraviolet lamp disposed on its inner side; a movable plate 5, movably installed inside the housing 1 and sleeved on the outside of the protective cover 3 through a through hole 6, with a first wiping block 7 in contact with the protective cover 3 on the inner wall of the through hole 6, and a second wiping block 8 in contact with the inner wall of the housing 1 on the outer wall of the movable plate 5; and a driving mechanism 9, disposed on the cover 2 and capable of driving the movable plate 5 to move relative to the protective cover 3, so as to drive the first wiping block 7 to wipe the outer wall of the protective cover 3 and drive the second wiping block 8 to wipe the inner wall of the housing 1.

[0041] In this application, the shell 1, cover 2, protective cover 3, ultraviolet lamp 4, and moving plate 5 are all cylindrical. The shell 1 and cover 2 are connected to form a disinfection chamber 12. The shell 1 and cover 2 serve as supporting structures and can be made of materials with high structural strength and resistance to rust, such as stainless steel. When the drive mechanism 9 operates, it can drive the moving plate 5 to move back and forth along the axis of the shell 1. During the reciprocating movement of the moving plate 5 along the axis of the shell 1, the moving plate 5 drives the first wiping block 7 and the second wiping block 8 to wipe the outer wall of the protective cover 3 and the inner wall of the shell 1 back and forth, respectively, to remove scale, algae, and other deposits on the outer wall of the protective cover 3 and the inner wall of the shell 1, ensuring the transmission of ultraviolet light and the sterilization effect, thereby improving water quality.

[0042] In one embodiment of this utility model, the sterilizer 100 further includes a water inlet 14, a water outlet 15, and a drain outlet 16. The water inlet 14 and the water outlet 15 are disposed on the outer wall of the housing 1, and the drain outlet 16 is disposed on the bottom surface of the housing 1. The water inlet 14 allows external water to be introduced into the housing 1, sterilized inside the housing 1, and then introduced into a water storage tank through the water outlet 15 for storage. After cleaning the sterilizer 100, scale, algae, and other deposits removed from the outer wall of the protective cover 3 and the inner wall of the housing 1 can be discharged outside the sterilizer 100 through the drain outlet 16.

[0043] In one embodiment of the present invention, the sterilizer 100 further includes a stand 17, a control box 18, and a connecting seat 19. The stand 17 is disposed on the bottom surface of the housing 1, the control box 18 is disposed on the outside of the cover 2, and the connecting seat 19 connects the protective cover 3 and the ultraviolet lamp 4 to the inside of the cover 2. The control box 18 is electrically connected to the drive unit 901 and controls the drive unit 901 to work.

[0044] In one embodiment of this utility model, the movable plate 5 is provided with a plurality of through holes 13, which are evenly distributed circumferentially along the axis of the movable plate 5. The plurality of through holes 13 allow water in the sterilizer 100 to pass freely through the movable plate 5, ensuring the normal movement of the movable plate 5.

[0045] In one embodiment of this utility model, the drive mechanism 9 includes a drive unit 901, a transmission unit 902, a moving unit 903, a connecting rod 10, and a push rod 11. The drive unit 901 is disposed on the outside of the cover 2. The transmission unit 902 is connected to the output shaft of the drive unit 901 via a coupling 904. The moving unit 903 is connected to the transmission unit 902 and serves as the power output component of the drive mechanism 9. It is connected to the connecting rod 10, and the other end of the connecting rod 10 is connected to the push rod 11. The other end of the push rod 11 is connected to the moving plate 5 to drive the moving plate 5 to move. In practical applications, the drive unit 901 can be a motor or a gear; the transmission unit 902 can be a screw; and the moving unit 903 can be a nut, wherein the screw and the nut are connected. In addition, the transmission unit 902 can also be a gear, and the moving unit 903 can also be a rack. The gear is mounted on the output shaft of the motor, and the gear and the rack are connected.

[0046] In one embodiment of this utility model, two push rods 11, two ultraviolet lamps 4, and two protective covers 3 are provided, and they are all symmetrically arranged with respect to the axis of the housing 1. The number of ultraviolet lamps 4 can be determined according to actual needs.

[0047] In the specific application of this application, when the drive mechanism operates, the drive unit drives the transmission unit to rotate forward or backward. The moving part, connected to the transmission unit, is connected to a connecting rod, causing it to reciprocate linearly on the transmission unit. The moving part can drive the connecting rod and push rod to move up and down, thereby driving the moving plate to reciprocate up and down along the axis of the housing. During the reciprocating movement of the moving plate along the axis of the housing, the first and second wiping blocks respectively wipe the outer wall of the protective cover and the inner wall of the housing, removing scale, algae, and other deposits from these surfaces, ensuring the transmission of ultraviolet light and the sterilization effect, thus improving water quality.

[0048] Example 2

[0049] Reference Figure 3 The second embodiment of this utility model proposes an automatic cleaning ultraviolet sterilizer 100. Compared with embodiment 1, the protective cover 3 and ultraviolet lamp 4 of the automatic cleaning ultraviolet sterilizer 100 in this embodiment are both coaxially arranged with the housing 1. The outer wall of the protective cover 3 is provided with a spirally extending guide rail 20. In addition to the first wiping block 7, the inner wall of the through hole 6 of the moving plate 5 is also provided with a guide rail groove 21, which is connected to the guide rail 20. The outer wall of the moving plate is no longer provided with a second wiping block 8. At the same time, the driving mechanism 9 can drive the moving plate 5 to move and rotate relative to the protective cover 3 simultaneously, so as to drive the first wiping block 7 to wipe the outer wall of the protective cover 3. The rest of the structure is the same as that of embodiment 1.

[0050] In this embodiment of the invention, when the drive mechanism 9 operates, it can drive the movable plate 5 to move up and down and rotate along the axis of the housing 1. Specifically, the drive mechanism 9 pushes the movable plate 5 downward along the axis of the housing 1; the drive mechanism 9 pulls the movable plate 5 upward along the axis of the housing 1. Since the guide rail 20 on the outer wall of the protective cover 3 is connected to the guide rail groove 21 on the inner wall of the movable plate 5, during the reciprocating motion of the movable plate 5 along the axis of the housing 1, the guide rail 20 and the guide rail groove 21 cause the movable plate 5 to simultaneously rotate around the axis of the protective cover 3, that is, around the axis of the housing 1. The movable plate 5 performs a combined rotational and linear motion during operation. As the moving plate 5 reciprocates up and down along the axis of the housing 1, the first wiping block 7 wipes the outer wall of the protective cover 3 back and forth to remove scale, algae and other deposits on the outer wall of the protective cover 3. Since the moving plate 5 not only wipes the outer wall of the protective cover 3 in a straight up and down reciprocating motion, but also rotates back and forth to wipe the outer wall of the protective cover 3, the wiping effect is better, ensuring the transmission of ultraviolet light and the sterilization effect, and improving water quality.

[0051] In one embodiment of this utility model, the drive mechanism 9 includes a drive unit 901, a transmission unit 902, a moving unit 903, a connecting rod 10, a push rod 11, and a pull rod 21. The drive unit 901 is disposed on the outside of the cover 2. The transmission unit 902 is connected to the output shaft of the drive unit 901 via a coupling 904. The moving unit 903 is connected to the transmission unit 902 and serves as the power output component of the drive mechanism 9. It is connected to the connecting rod 10, and the other end of the connecting rod 10 is connected to the push rod 11. The other end of the push rod 11 is connected to the pull rod 21. The push rod 11 only extends to the upper side of the moving plate 5 and is not connected to the moving plate 5. The pull rod 21 extends around the moving plate 5 to the lower side of the moving plate 5. When the push rod 11 and the pull rod 21 move, they can respectively contact the upper and lower sides of the moving plate 5. When the moving plate 5 rotates, it will not interfere with the pull rod 21 to the point of collision.

[0052] Specifically, the moving part 903 can drive the connecting rod 10, the push rod 11 and the pull rod 21 to move up and down. When the moving part 903 drives the connecting rod 10 and the push rod 11 to move down, the push rod 11 pushes the moving plate 5 to move down along the axis of the housing 1. When the moving part 903 drives the connecting rod 10 and the pull rod 21 to move up, the pull rod 21 pulls the moving plate 5 to move up along the axis of the housing 1.

[0053] In practical applications, the drive unit 901 can be a motor or a drive unit; the transmission unit 902 can be a screw, and the moving part 903 can be a nut, wherein the screw and the nut are connected in a mating manner. Alternatively, the transmission unit 902 can also be a gear, and the moving part 903 can also be a rack, with the gear mounted on the output shaft of the motor and the gear and rack connected in a mating manner.

[0054] In one embodiment of this utility model, the length of the first rubbing block 7 is greater than the length of the pull rod 21 in the axial direction. See also Figure 3 Since the pull rod 21 is connected to the push rod 11 and extends around the moving plate 5 to the lower side of the moving plate 5, during the process of the drive mechanism 9 driving the push rod 11 and the pull rod 21 to move up and down, the pull rod 21 will reach and touch the cover 2 or the housing 1 before the moving plate 5. Therefore, the length of the first wiping block 7 is set to be greater than the length of the pull rod 21. Before the pull rod 21 touches the cover 2 or the housing 1, the first wiping block 7 can have completed the full wiping of the outer wall of the protective cover 3, and the wiping effect will be better.

[0055] In one embodiment of this invention, the protective cover 3 is made of a high-strength transparent material, such as tempered glass, but is not limited thereto. The high-strength transparent material can withstand the movement between the guide rail 20 and the guide rail groove 21.

[0056] In one embodiment of this utility model, wear-resistant blocks 23 are respectively provided at the ends of the push rod 11 and the pull rod 22 near the moving plate 5. When the push rod 11 pushes the moving plate 5 down or the pull rod 22 pulls the moving plate 5 up and the moving plate 5 rotates at the same time, the friction between the push rod 11 and the moving plate 5 and the pull rod 22 and the moving plate 5 can be reduced, thereby reducing wear.

[0057] In one embodiment of this utility model, the sterilizer 100 further includes a water inlet 14, a water outlet 15, and a drain outlet 16. The water inlet 14 and the water outlet 15 are disposed on the outer wall of the housing 1, and the drain outlet 16 is disposed on the bottom surface of the housing 1. The water inlet 14 allows external water to be introduced into the housing 1, sterilized inside the housing 1, and then introduced into a water storage tank through the water outlet 15 for storage. After cleaning the sterilizer 100, scale, algae, and other deposits removed from the outer wall of the protective cover 3 and the inner wall of the housing 1 can be discharged outside the sterilizer 100 through the drain outlet 16.

[0058] In one embodiment of the present invention, the sterilizer 100 further includes a stand 17, a control box 18, and a connecting seat 19. The stand 17 is disposed on the bottom surface of the housing 1, the control box 18 is disposed on the outside of the cover 2, and the connecting seat 19 connects the protective cover 3 and the ultraviolet lamp 4 to the inside of the cover 2. The control box 18 is electrically connected to the drive unit 901 and controls the drive unit 901 to work.

[0059] In the specific application of this application, when the drive mechanism operates, the drive unit drives the transmission unit to rotate forward or backward. The moving part, connected to the transmission unit, is connected to a connecting rod, causing it to reciprocate linearly on the transmission unit. The moving part can drive the connecting rod, push rod, and pull rod to move up and down. When the moving part drives the connecting rod and push rod downward, the push rod pushes the moving plate downward along the axis of the housing; when the moving part drives the connecting rod and pull rod upward, the pull rod pulls the moving plate upward along the axis of the housing. Because the guide rail on the outer wall of the protective cover is connected to the guide rail groove on the inner wall of the moving plate, during the reciprocating motion of the moving plate along the axis of the housing, the guide rail and guide rail groove cause the moving plate to simultaneously rotate around the axis of the protective cover, i.e., rotate around the axis of the housing. The moving plate performs a combined rotational and linear motion during operation. As the moving plate reciprocates up and down along the axis of the shell, the first wiping block wipes the outer wall of the protective cover back and forth, removing scale, algae and other deposits. Since the moving plate not only wipes the outer wall of the protective cover by moving up and down in a straight line, but also rotates back and forth to wipe the outer wall of the protective cover, the wiping effect is better, ensuring the transmission of ultraviolet light and the sterilization effect, thus improving water quality.

[0060] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
