Abstract
Description
Technical Field
[0001] This utility model relates to the field of sterilization and disinfection equipment technology, specifically to a sterilizer with an automatic cleaning function. Background Technology
[0002] As people's living standards improve, their requirements for water quality are also increasing. Traditional water treatment methods, such as chlorination and ozone, while capable of sterilization and disinfection to some extent, pose potential risks to human health and the environment. Ultraviolet (UV) sterilization technology, as a non-chemical sterilization method, is gradually gaining attention.
[0003] Ultraviolet (UV) sterilizers achieve sterilization and disinfection by emitting high-intensity UV radiation that destroys the DNA structure of bacteria, viruses, and other microorganisms in water. Compared with traditional chemical sterilization methods, UV sterilizers have advantages such as high sterilization efficiency, no secondary pollution, and simple operation and maintenance. Referring to Chinese invention patent application number 202410778641.3, which discloses a microbial treatment UV sterilization device, two UV lamps are inserted into a disinfection chamber to sterilize the microorganisms. A cleaning mechanism periodically cleans the surface of the isolation tubes around the UV lamps to maintain the UV radiation effect and improve sterilization efficiency.
[0004] However, in this structure, since the cleaning collar is fitted on the outer surface of the isolation tube, the cleaning sponge is easily damaged after long-term exposure to ultraviolet light and water erosion, and cannot play an effective cleaning role. If you want to replace the cleaning sponge, you may need to remove multiple components such as the threaded rod and the micro motor. Therefore, maintenance and disassembly are relatively inconvenient and will greatly increase maintenance costs. Utility Model Content

[0027] like Figures 1 to 5As shown, this embodiment discloses a sterilizer with an automatic cleaning function, including a sterilizer body 1 and a cleaning device 2. The sterilizer body 1 has an installation cavity 10 and a sterilizing lamp 11 inside. The installation cavity 10 is vertically connected and water flows through it. The sterilizing lamp 11 extends horizontally from one side of the sterilizer body 1 into the installation cavity 10 from the outside to the inside. One end of the lamp extends into the installation cavity 10 and exits from the other side of the sterilizer body 1 and is fixed. The cleaning device 2 is movably sleeved on the sterilizing lamp 11. Specifically, the cleaning device 2 includes a telescopic rod 21 fixed to the inner wall of the installation cavity 10, a movable part 22 connected to the telescopic end of the telescopic rod 21, a cleaning ring 23 snapped onto the movable part 22, and a cleaning cotton 24 snapped onto the inner side of the cleaning ring 23. The cleaning ring 23 is sleeved on the sterilizing lamp 11, and the outer side of the cleaning cotton 24 is snapped onto the cleaning ring. The inner side of the cleaning ring 23 is tightly fitted onto the outer surface of the germicidal lamp tube 11. The telescopic rod 21 drives the moving part 22 to move, and at the same time, the cleaning ring 23 drives the cleaning cotton 24 to scrape the outer surface of the germicidal lamp, thereby achieving a cleaning effect. The telescopic rod 21 is preferably a pneumatic rod. The telescopic rod 21 is fixed from one side of the end sterilizer body 1 and connected to the air supply pipe for air supply, thereby realizing power transmission. The moving part 22 has a mounting hole 220 in the middle. The cleaning ring 23 is movably engaged in the mounting hole 220. The cleaning ring 23 includes two relatively cooperating retaining rings 230. After the two retaining rings 230 are engaged, they form a groove 234 for engaging the cleaning cotton 24. When the cleaning cotton 24 needs to be replaced, the two retaining rings 230 can be removed and the cleaning cotton 24 can be easily taken out and replaced without disassembling other parts, thereby reducing maintenance costs.
[0028] In this embodiment, the retaining ring 230 includes a retaining ring 230 body with an annular sheet structure. An annular assembly portion 231 extends vertically to one side of the retaining ring 230 body. The assembly portion 231 divides the retaining ring 230 body into an outer limiting portion 232 and an inner snap-fit portion 233. Two retaining rings 230 are connected to each other through the assembly portion 231. Specifically, one retaining ring 230 has an external thread on the outer side of the assembly portion 231, and the other retaining ring 230 has an internal thread on the inner side of the assembly portion 231. The two retaining rings 230 are screwed together by the external and internal threads. After assembly, the limiting portions 232 of the two retaining rings 230 abut against both sides of the mounting hole 220 to form a limiting position. The snap-fit portion 233 on the two retaining rings 230 and the assembly portion 231 with external threads form an annular groove 234.
[0029] In this embodiment, in order to improve the stability of the moving part 22, positioning guide rods 13 are respectively provided on the upper and lower sides of the germicidal lamp in the mounting cavity 10. The upper and lower parts of the moving part 22 are respectively provided with guide rods 221 extending outward. The extended end of the guide rod 221 is provided with a U-shaped opening 222. The moving part 22 is slidably engaged between the two positioning guide rods 13 through the U-shaped opening 222. When the telescopic rod 21 extends or retracts, it drives the moving part 22 to move along the direction of the positioning guide rod 13, thereby preventing the moving part 22 from deflecting.
[0030] Furthermore, to improve the cleaning effect on the germicidal lamp tube 11, the cleaning device 2 includes two sets of parallel cleaning rings 23 and moving parts 22 corresponding to the cleaning rings 23. The two sets of moving parts 22 are connected by connecting rods 25. To improve structural stability, three connecting rods 25 are provided, and the three connecting rods 25 are triangularly distributed and connected to the moving parts 22. Specifically, the telescopic rod 21 is provided on one side of the moving parts 22, and one set of moving parts 22 has a connecting ear 223 extending to one side of the telescopic rod 21. The moving parts 22 are connected to the telescopic end of the telescopic rod 21 through the connecting ear 223, thereby enabling the telescopic rod 21 to drive the two sets of moving parts 22 to move simultaneously.
[0031] In this embodiment, the upper and lower parts of the sterilizer body 1 are respectively provided with connection ports 12 for connecting pipes, and the upper and lower connection ports 12 are provided with through holes 120 that connect to the mounting cavity 10. Preferably, the upper and lower through holes 120 are located on the same straight line to reduce the resistance of water flow.
[0032] In this embodiment, the two connection ports 12 are vertically connected, so the sterilizer can be connected to a high-flow-rate, high-pressure water pipe. In order to achieve an effective sterilization effect, the sterilizing lamp tube 11 uses a high-power ultraviolet sterilizing lamp for sterilization and disinfection, specifically a sterilizing lamp tube 11 with a power of 300 watts or more.
[0033] In this embodiment, since the germicidal lamp 11 is located inside the sterilizer body 1, an observation port 15 is provided on the sterilizer body 1 to facilitate observation of the operation of the germicidal lamp 11. The observation port 15 is sealed by UV-resistant glass, and maintenance personnel can observe the operation of the internal germicidal lamp 11 through the UV-resistant glass.
[0034] Furthermore, the sterilizer body 1 is also provided with a plurality of pre-installation ports 14 for pre-installing monitoring elements. After the monitoring elements are installed through the pre-installation ports 14, the internal working condition of the sterilizer body 1 can be monitored, such as temperature monitoring, water pressure monitoring, and light intensity monitoring of the sterilizing lamp tube 11.
[0035] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
