Description

Technical Field

[0001] The present invention belongs to the field of sterilization products, and specifically relates to an ultraviolet sterilization device with cleaning function and an assembly method thereof Background Art

[0002] After long-term use of the ultraviolet sterilization device, a large amount of dirt and scale will be deposited on the surface of the lamp tube due to various impurities in the water, affecting the sterilization effect of the ultraviolet lamp.

[0003] In the past, ultraviolet sterilization devices usually had the end face of the device tube shell designed as a detachable flange end plate structure for easy disassembly and cleaning. The surface of the lamp tube inside the tube shell can be cleaned by removing the flange end plate. However, such ultraviolet sterilization devices need to be shut down for disassembly and cleaning, and cannot be cleaned online while the ultraviolet sterilization lamp is working.

[0004] There are also ultraviolet sterilization devices with online cleaning functions on the market, such as a ultraviolet sterilizer with a self-cleaning function disclosed in Chinese patent publication number CN117401769A, and a cleaning mechanism for ultraviolet sterilization equipment disclosed in Chinese patent publication number CN105598106B. They clean the ultraviolet lamp online by arranging a cleaning component in the tube shell. However, since such a cleaning component has a complex structure and many parts, it is still necessary to design the end face of the tube shell as a detachable flange end plate. In this way, when the sterilization device is assembled, the flange end plate is removed so that the various parts of the cleaning component can be installed inside the tube shell from the end face of the tube shell.

[0005] As can be seen from the above, in the existing technical solutions, whether it is an ultraviolet sterilization device that needs to be shut down for disassembly and cleaning, or an ultraviolet sterilization device that can be cleaned online, it is necessary to design the end face of the tube shell of the sterilization device as a detachable flange end plate structure. However, with the setting of the flange end plate, the tube shell has the problem of sealing failure. After long-term use, the ultraviolet sterilization device is prone to water seepage at the flange end plate of the tube shell, and the structure of the flange end plate also increases the processing and manufacturing cost of the tube shell. Summary of the invention

[0006] Based on the deficiencies of the existing ultraviolet sterilization device with cleaning function described in the background technology, the present application provides an ultraviolet sterilization device with cleaning function and an assembly method thereof, which can install cleaning-related components in the tube shell without providing a detachable flange end plate on the end face of the tube shell.

After the two ends of the lamp tube are limited in the corresponding installation interfaces by the limiting caps, the lamp tube can be limited and installed in the tube shell. In this way, the lamp tube is easy to install and can also be disassembled and cleaned. A wire threading hole is opened on the limiting cap at one end of the tube shell to facilitate the setting of the wires of the ultraviolet lamp.

[0011] Furthermore, the scraper blade is arranged according to the following mounting structure: the required cleaning rod is provided with two annular grooves at the corresponding positions of the scraper blade, the handle of the scraper blade is provided with a mounting hole, the scraper blade is sleeved between the two corresponding annular grooves of the cleaning rod through the mounting hole of its handle, an open retaining ring is clamped in the annular groove of the cleaning rod through its open groove, each annular groove corresponds to an open retaining ring, the handle of the scraper blade can be limited by the corresponding two retaining rings, and thus it is limitedly installed on the cleaning rod, and such a mounting structure is easy to assemble.

[0012] Furthermore, the diameter of the scraper annular ring is smaller than the diameter of the water inlet joint and / or the water outlet joint, so that when the sterilization device is assembled, it is convenient to place the scraper into the tube shell from the water inlet joint or the water outlet joint of the tube shell.

[0013] Furthermore, a flushing joint is 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 through the flushing joint.

[0014] Preferably, a plurality of through holes are distributed on the annular ring of the scraper blade, and a steel wire is wound around the annular ring of the scraper blade through the through holes, and the contact friction between the steel wire and the lamp tube can further increase the cleaning ability of the scraper blade.

[0015] Preferably, a mushroom-head handle is fixedly connected to one end of the cleaning rod outside the tube shell, so that the user can hold and push the cleaning rod more easily.

The assembler then puts the open retaining ring into the tube shell from the water inlet joint or the water outlet joint, and clamps the open retaining ring into the corresponding annular groove of the cleaning rod through its open groove. Each annular groove corresponds to an open retaining ring. In this way, the handle of the scraper can be limitedly installed on the cleaning rod through these two open retaining rings.

[0019] S3. Insert the lamp tube into the tube shell from the installation interface on one end of the tube shell. At the same time, the assembler adjusts the position of the scraper inside the tube shell from the water inlet joint or the water outlet joint so that the end of the lamp tube can pass through the annular ring of the scraper to allow the annular ring of the scraper to be sleeved on the lamp tube. After the other end of the lamp tube is also placed in the installation interface on the other end of the tube shell, the limiting caps are respectively screwed on the installation interfaces at both ends of the lamp tube to limit the two ends of the lamp tube so that the lamp tube can be assembled, so that the scraper can also be sleeved on the lamp tube.
