[0033] See Figure 1 , Figure 1 An embodiment of this application is shown. Figure 1 This is a schematic diagram of the structure of the ultraviolet lamp 20 in one embodiment of this application. Figure 2 for Figure 1 A schematic diagram of the cleaning device 10 is shown, omitting the cylinder 21. (Combined with...) Figure 2As shown, the cleaning device 10 provided by an embodiment of the present application is used for cleaning an ultraviolet lamp tube. The ultraviolet lamp tube comprises a barrel 21 and a quartz tube 23 arranged in the inner cavity of the barrel 21. The cleaning device 10 comprises a first magnetic mechanism 100, a second magnetic mechanism 200, a driving mechanism 300 and a cleaning mechanism 400. The first magnetic mechanism 100 is arranged between the barrel 21 and the quartz tube 23. The second magnetic mechanism 200 is arranged outside the barrel 21 and is attracted to the first magnetic mechanism 100. The driving mechanism 300 is used to drive the second magnetic mechanism 200 to move along the axis of the barrel 21 and / or rotate around the axis of the barrel 21, so that the first magnetic mechanism 100 is driven to move along the axis of the quartz tube 23 and / or rotate around the axis of the quartz tube 23 in the barrel 21 under the attraction of the second magnetic mechanism 200. The cleaning mechanism 400 is connected to the first magnetic mechanism 100 and is used to clean the outer wall of the quartz tube 23 and the inner wall of the barrel 21 under the driving of the first magnetic mechanism 100.

[0034] The cleaning device 10 described above realizes the magnetic transmission of the second magnetic mechanism 200 and the first magnetic mechanism 100 without contact, by arranging the first magnetic mechanism 100 between the barrel 21 and the quartz tube 23 and arranging the second magnetic mechanism 200 outside the barrel 21 and attracted to the first magnetic mechanism 100. Therefore, the inner cavity of the barrel 21 of the ultraviolet lamp tube can maintain strict cleanliness during the cleaning of the cleaning device 10, and the cross-contamination problem caused by the arrangement of the lead screw 320 in the barrel 21 is avoided.

[0035] In combination with Figure 3 and Figure 4 In some embodiments, the first magnetic mechanism 100 comprises a rotating body 110 and a first magnet 120. The rotating body 110 is provided with a through hole 110a at the center thereof, and the rotating body 110 can be sleeved on the quartz tube 23 through the through hole 110a. The second magnet 220 is arranged along the circumference of the rotating body 110 and can be attracted to the second magnetic mechanism 200.

[0036] Specifically, by arranging the second magnet 220 along the circumference of the rotating body 110, the number of the second magnet 220 can be adjusted to change the magnetic attraction force between the second magnet 220 and the second magnetic mechanism 200, so as to change the friction torque between the cleaning structure and the ultraviolet lamp 20.

[0037] In addition, in some embodiments, in combination with Figure 1 and Figure 2 The first magnetic mechanism 100 comprises a rotating body 110. The rotating body 110 is provided with a through hole 110a at the center thereof, and the rotating body 110 can be sleeved on the quartz tube 23 through the through hole 110a. The rotating body 110 has magnetism, so that the rotating body 110 can be attracted to the second magnetic mechanism 200.

[0038] Specifically, the rotating body 110 can be made of a magnetic material to realize mutual attraction with the second magnetic mechanism 200, so as to ensure the magnetic attraction area of the rotating body 110 and the second magnetic mechanism 200 and improve the magnetic attraction effect.

[0039] In some embodiments, the cleaning mechanism 400 includes a first scraping structure 410 arranged on the hole wall of the through hole 110a of the rotating body 110 and a second scraping structure 420 arranged along the circumference of the outer ring of the rotating body 110, so as to clean the inner wall of the cylinder 21 and the outer wall of the quartz tube 23 at the same time.

[0040] Specifically, the first scraping structure 410 and the second scraping structure 420 can be protruding structures or scraping blades arranged on the wall. When the through hole 110a is sleeved on the quartz tube 23, the first scraping structure 410 is arranged around the wall surface of the quartz tube 23, and at the same time, the second scraping structure 420 is in contact with the inner wall of the cylinder 21 on the surface of the outer ring of the rotating body 110, so as to realize that the second scraping structure 420 scrapes the inner wall of the cylinder 21 and the first scraping structure 410 scrapes the outer wall of the quartz tube 23 during the movement of the rotating body 110, thereby ensuring the cleaning effect.

[0041] It should be noted that the ultraviolet device belongs to a light decomposition product, and the light is used to treat residual chlorine and microorganisms in water by energy. The entire ultraviolet treatment cavity needs to realize a full reflection state to enhance the ultraviolet irradiation intensity. Therefore, the inner wall surface of the cylinder 21 is usually mirror polished to facilitate further reflection of ultraviolet light and ensure the ultraviolet irradiation intensity in the flow area. Therefore, the above cleaning of the outer wall of the quartz tube 23 and the inner wall of the cylinder 21 by the first scraping structure 410 and the second scraping structure 420 at the same time is beneficial to improve the ultraviolet irradiation intensity.

[0042] In combination with Figure 2 As shown in the drawings, in some embodiments, the rotating body 110 includes an inner ring 111, an outer ring 112, and at least two spokes 113. The inner ring 111 and the outer ring 112 are coaxial and connected by the spokes 113. The water gap 110b is formed between the inner ring 111 and the outer ring 112, so as to improve the flowability of the cleaning liquid during the cleaning process and ensure the cleaning effect. Specifically, the spokes 113 are at least two to realize the connection between the inner ring 111 and the outer ring 112 and ensure the structural stability. The specific number can be determined according to the structural strength.

[0043] In combination with Figure 3 and Figure 4As shown, in some embodiments, the second magnetic mechanism 200 comprises a support frame 210 and second magnets 220, the support frame 210 is capable of being arranged around the cylinder 21, the support frame 210 is connected with a driving mechanism 300, the driving mechanism 300 is used for driving the support frame 210 to move along the axis of the cylinder 21, the second magnets 220 are distributed along the extension path of the support frame 210, and the second magnets 220 are used for being mutually attracted with the first magnetic mechanism 100, so that the first magnetic mechanism 100 can move together with the second magnetic mechanism 200.

[0044] It should be noted that the extension path of the support frame 210 refers to the limitation on the overall shape of the support frame 210. Specifically, the support frame 210 can be in the shape of U, O, etc.

[0045] Understandably, in this embodiment, when the first magnetic mechanism 100 is provided with the first magnets 120, the number of the second magnets 220 is consistent with the number of the first magnets 120. Preferably, in an embodiment, the number of the second magnets 220 and the number of the first magnets 120 are both 3, and one magnet of each is arranged at the middle position, and the other two magnets are symmetrically arranged on both sides of the above-mentioned middle magnet along the extension path of the support frame 210, so that the stress distribution of the magnetic attraction force between the second magnets 220 and the first magnetic mechanism 100 can be improved, thereby ensuring the magnetic attraction effect.

[0046] Further, in combination with Figure 1 As shown, in some embodiments, the support frame 210 is provided with a avoiding structure 210a along the extension path thereof, and the cylinder 21 is connected with a liquid inlet and outlet pipe, when the support frame 210 moves along the axis of the cylinder 21, the liquid inlet and outlet pipe can pass through the avoiding structure 210a, thereby improving the range of movement and ensuring the cleaning effect.

[0047] Specifically, the above-mentioned avoiding structure 210a can be a notch structure provided on the support frame 210, at this time the support frame 210 is roughly in the shape of U. In addition, in combination with Figure 3 As shown, in this embodiment, when the number of the second magnets 220 and the number of the first magnets 120 are both 3, two magnets can be arranged at the two end positions of the support frame 210, and the connecting line of the three magnets can be an equilateral triangle, so that the stability of the stress can be ensured.

[0048] In combination with Figure 4 As shown, in some embodiments, the second magnets 220 are slidingly connected to the support frame 210, and the second magnets 220 are capable of sliding relative to the support frame 210 along the extension path of the support frame 210, so as to drive the first magnetic mechanism 100 to rotate around the axis of the quartz tube 23, thereby improving the cleaning effect of the ultraviolet lamp 20.

[0049] Specifically, in some embodiments, the support frame 210 is provided with a sliding groove, and the second magnet 220 is slidingly arranged in the sliding groove; in some embodiments, the second magnet 220 is in a U shape, and the second magnet 220 is clamped on the support frame 210 and can slide relative to the support frame 210. The above embodiments show the connection mode of the sliding connection of the second magnet 220 and the support frame 210. When the second magnet 220 slides relative to the support frame 210, the rotor 110 in the cylinder 21 can be driven to rotate, so as to realize the cleaning of the cleaning structure in the rotating direction of the quartz tube 23, thereby improving the cleaning effect.

[0050] Understandably, in this embodiment, the second magnet 220 can be connected with the driving mechanism 300 to realize the automation of the sliding of the second magnet 220. It should be noted that the driving mechanism 300 can include a first driving member for driving the support frame 210 to move and a second driving member (not shown) for driving the second magnet 220 to slide. The second driving member can be a pushing rod connected with the second magnet 220, or an additional movable third magnet (not shown). The third magnet can attract the second magnet 220, so that the second magnet 220 moves with the third magnet, and the like. Furthermore, the operator can manually move the second magnet 220 to realize the sliding of the second magnet 220.

[0051] Further, in some embodiments, the second magnet 220 is at least three, and is connected and fixed with each other, so that the overall linkage during the sliding of the plurality of second magnets 220 can be realized, and the working stability can be ensured. Specifically, the plurality of second magnets 220 can be connected with each other by a rod or a connecting wire, and the like. In addition, the plurality of second magnets 220 can also realize linkage sliding through mutual repulsive force. The above structure is simple and reliable, and greatly improves the structural stability and manufacturing cost of the cleaning device.

[0052] In one embodiment, in combination with Figure 1 , Figure 2 , Figure 5 and Figure 6 , the present application also provides a UV lamp 20, which comprises a cylinder 21, a quartz tube 23, and the above-described cleaning device 10. The quartz tube 23 is arranged in the inner cavity of the cylinder 21.

[0053] Specifically, the UV lamp 20 further comprises support feet 24, and the support feet 24 are at least two and are connected with the mounting plate 22. In some embodiments, the mounting plate 22 is in a circular shape, and the quartz tube 23 passes through the center of the mounting plate 22 and protrudes from the surface of the mounting plate 22.

[0054] The ultraviolet lamp 20 is provided with the first magnetic mechanism 100 sleeved between the cylinder 21 and the quartz tube 23 and the second magnetic mechanism 200 arranged outside the cylinder 21 and attracting the first magnetic mechanism 100, so that the second magnetic mechanism 200 of the cleaning device 10 is magnetically driven without contacting the first magnetic mechanism 100, the inner cavity of the cylinder 21 of the ultraviolet lamp 20 is kept clean, and cross contamination caused by the screw rod 320 arranged in the cylinder 21 is avoided.

[0055] In combination Figure 1 As shown in some embodiments, the ultraviolet lamp tube further comprises two mounting plates 22 respectively arranged at both ends of the cylinder 21, the driving mechanism 300 of the cleaning device 10 comprises a motor 310, a screw rod 320, a first guide rod 330 and a second guide rod 340, the screw rod 320, the first guide rod 330 and the second guide rod 340 are respectively arranged in the second magnetic mechanism 200, and both ends of each are respectively connected to the two mounting plates 22, the screw rod 320 is connected to the motor 310, and the motor 310 is used to drive the screw rod 320 to rotate to drive the second magnetic mechanism 200 to move along the first guide rod 330 and the second guide rod 340, so as to improve the stability of movement.

[0056] In combination Figure 1 And Figure 2 As shown in some embodiments, the screw rod 320 is arranged in the support frame 210 of the cleaning device 10, the screw rod 320 is threadedly connected to the support frame 210, and when the support frame 210 is arranged on the cylinder 21, the screw rod 320 is connected to the lowest position of the support frame 210, and the first guide rod 330 and the second guide rod 340 are arranged on both sides of the screw rod 320, so as to ensure the force balance during driving, form three-point force, and improve the working reliability of the overall structure.

[0058] Specifically, the driving plate 22a is mounted on the support leg 24 at one end of the cylinder 21 and can rotate relative to the support leg 24. The support plate 22b is arranged at the other end of the cylinder 21, and a circular rotating groove 22e is formed on the surface of the support plate 22b. The ends of the lead screw 320, the first guide rod 330, and the second guide rod 340 can be clamped into the rotating groove 22e and can slide along the extension track of the rotating groove 22e, so that the lead screw 320, the first guide rod 330, and the second guide rod 340 can rotate around the axis of the cylinder 21. Specifically, in this embodiment, the ends of the lead screw 320, the first guide rod 330, and the second guide rod 340 can be provided in the form of pulley members, rollers, or balls, etc., to improve the sliding effect.
