Description

Technical Field

[0001] This utility model belongs to the field of sterilization products, specifically relating to an online cleaning component of an ultraviolet sterilization device. Background Technology

[0002] After prolonged use, ultraviolet sterilization devices accumulate a large amount of dirt and scale on the surface of the lamp tubes due to various impurities in the water, affecting the sterilization effect of ultraviolet lamp irradiation.

[0003] In the past, ultraviolet sterilization devices were designed with detachable flange end plates on the end face of the device shell for easy disassembly and cleaning. The surface of the lamp tube inside the shell could be cleaned by removing the flange end plate. However, such ultraviolet sterilization devices required to be shut down for disassembly and cleaning and could not be cleaned online while the ultraviolet sterilization lamp was working.

[0004] Currently, there are some UV sterilization devices on the market with online cleaning functions. For example, Chinese Patent No. CN117401769A discloses a self-cleaning UV sterilizer, and Chinese Patent No. CN105598106B discloses a cleaning mechanism for UV sterilization equipment. These devices clean the UV lamps online by setting a cleaning component inside the tube housing. However, due to the complex structure and numerous parts of such cleaning components, production and assembly are difficult. Often, the end face of the tube housing is designed as a detachable flange plate. The flange plate is removed, and the various components of the cleaning component are installed inside the tube housing from the end face to reduce the assembly difficulty. However, the detachable flange plate design of the sterilization device's tube housing end face has the problem of sealing failure. After long-term use, the UV sterilization device is prone to water leakage at the flange plate of the tube housing, and the structure of the flange plate also increases the processing and manufacturing cost of the tube housing. Utility Model Content

[0005] In view of the shortcomings of existing ultraviolet sterilization devices with cleaning functions described in the background art, this application provides an online cleaning component for an ultraviolet sterilization device, which has an online cleaning function. Its structure is simple and compact. By pushing and pulling the cleaning rod, the dirt on the lamp tube can be scraped off by the scraper, which is convenient to use. Moreover, there is no need to set a detachable flange end plate on the end face of the tube shell, so the cleaning-related components can be installed in the tube shell, and the assembly is also convenient and quick.

[0006] A disclosed online cleaning component for an ultraviolet sterilization device includes a housing, a lamp tube, a waterproof connector, a cleaning rod, and a scraper.

[0007] A lamp tube is installed inside the casing, and the lamp tube contains an ultraviolet germicidal lamp. A waterproof connector is connected to one end of the casing. One end of the cleaning rod passes through the waterproof connector and is placed inside the casing. The main body of the scraper is ring-shaped, and the ring of the scraper is fitted around the lamp tube. The handle of the scraper is installed on the cleaning rod and can move with the cleaning rod. In this way, the cleaning rod is pushed and pulled inside the casing, and the dirt on the lamp tube can be scraped off by the scraper. It is convenient to use, so that the ultraviolet germicidal device has an online cleaning function.

[0008] Preferably, two lamps are installed inside the tube housing, and the cleaning rod is located between the two lamps. It is equipped with four scrapers, with two scrapers corresponding to each lamp installed in the middle and end of the cleaning rod, respectively. This sterilization device has two built-in ultraviolet germicidal lamps, which improves the sterilization efficiency, and the cleaning function of two lamps can be achieved simultaneously through one cleaning rod.

[0009] Preferably, the specific installation structure of the lamp tube is as follows: Each of the two end faces of the tube shell is connected to an installation interface at a corresponding position of the lamp tube. Both ends of the lamp tube are placed within the corresponding installation interfaces, and corresponding limiting caps are threaded onto the installation interfaces. Thus, the lamp tube is positioned within the tube shell by the limiting caps, making installation convenient and allowing for easy disassembly and cleaning. A wire hole is provided on the limiting cap at one end of the tube shell for easy wiring of the ultraviolet lamp.

[0010] Preferably, a flushing connector is also connected to the side of the tube shell, and the dirt scraped off by the scraper on the lamp tube can be flushed out of the device from the flushing connector.

[0011] Preferably, the annular ring of the scraper has multiple through holes, through which steel wire is wound around the annular ring of the scraper. The contact friction between the steel wire and the lamp tube can further increase the cleaning ability of the scraper.

[0012] Preferably, a mushroom-shaped handle is fixedly connected to one end of the cleaning rod outside the casing, making it easier for users to grip and push the cleaning rod.

[0013] In a further embodiment, the online cleaning component of the ultraviolet sterilization device further includes an inlet connector and an outlet connector, which are respectively connected to the side of the tube housing.

An open retaining ring is fitted into the annular groove of the cleaning rod through its open groove. Each annular groove corresponds to an open retaining ring, so that the handle of the scraper can be limited by the corresponding two retaining rings, thus limiting its installation on the cleaning rod. This installation structure facilitates assembly. The diameter of the scraper annular ring is smaller than the diameter of the inlet connector and / or the outlet connector, so that during the assembly of the sterilization device, it is convenient to place the scraper into the tube housing from the inlet connector or the outlet connector of the tube housing.

[0014] The specific assembly method of the online cleaning component of the above-mentioned ultraviolet sterilization device is as follows:

[0015] S1. Place the scraper inside the pipe shell from the inlet or outlet joint;

[0016] S2. After passing one end of the cleaning rod through the waterproof connector, place it inside the tube housing. At the same time, the assembler adjusts the position of the scraper inside the tube housing from the inlet or outlet connector so that the end of the cleaning rod can pass through the mounting hole of the scraper handle and the scraper handle fits between the corresponding two annular grooves of the cleaning rod. The assembler then places the open retaining ring inside the tube housing from the inlet or outlet connector and clamps the open retaining ring into the corresponding annular groove of the cleaning rod through its open groove. Each annular groove corresponds to one open retaining ring. In this way, the scraper handle can be limited and installed on the cleaning rod by these two open retaining rings.

[0017] S3. Insert the lamp tube into the tube housing from the installation interface on one end face of the tube housing. At the same time, the assembler adjusts the position of the scraper inside the tube housing from the inlet or outlet connector so that the end of the lamp tube can pass through the ring of the scraper and the ring of the scraper fits onto the lamp tube. After the other end of the lamp tube is also placed in the installation interface on the other end face of the tube housing, tighten the upper limit caps on the installation interfaces at both ends of the lamp tube to limit the two ends of the lamp tube and complete the assembly of the lamp tube. In this way, the scraper can also fit onto the lamp tube.
