Description

Technical Field

[0001] The utility model relates to the technical field of sterilization and disinfection of water bodies in water-related equipment, in particular to an ultraviolet water sterilization module. Background Art

[0002] Water purifiers, humidifiers, ice makers and other products mostly use static water sterilization modules to sterilize the water in the water tank to obtain a sterile or less-bacterial water environment. Such static water modules usually use ultraviolet LEDs as sterilization light sources and quartz glass as protective covers for ultraviolet LEDs, which can prevent water from entering the module and causing failure. The module shell is mostly made of plastic materials, such as PP, PC, POM, etc., and is effectively connected to the entire machine such as water purifiers, humidifiers, ice makers, etc.

[0003] Quartz glass is a high-purity SiO2 sheet. Currently, a silicone sealing ring is usually used to install it between a plastic shell and the quartz glass to achieve the purpose of waterproofing. However, this method requires additional silicone sealing rings to be added to the shell and the quartz glass during the installation process. There are many steps, resulting in low assembly efficiency. In addition, organic glue can be used for bonding, but there is a risk of leakage, and the organic glue is easy to overflow into the water body and cause pollution. Moreover, with the long-term use of the ultraviolet module, ultraviolet rays will age the organic glue, causing the quartz glass to fall off, making it very risky to leak in the later stage of use. Moreover, the connection between the nut and the rubber ring is only a simple fitting connection relationship, and the connection is not tight enough. When installing the quartz glass and the lamp board, it is impossible to quickly determine the installation position of the quartz glass and the lamp board, and it is necessary to measure and determine the center position, which is very troublesome and affects the production efficiency. Therefore, a UV water sterilization module is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an ultraviolet water sterilization module to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A UV water sterilization module comprises a wiring harness and a nut, wherein the bottom end of the wiring harness is fixedly connected to a lamp board, the outer side of the nut is fixedly connected to an auxiliary block, the bottom end of the nut is fixedly connected to a connecting ring, the outer side of the connecting ring is fixedly connected to a limiting block, a waterproof rubber ring is provided below the nut, a first limiting groove is provided at the top of the waterproof rubber ring, a second limiting groove is provided at the top of the first limiting groove, a third limiting groove located below the second limiting groove is provided on the inner side of the first limiting groove, the inner sides of the nut and the waterproof rubber ring are spirally connected to a main body shell, the bottom end of the main body shell is fixedly connected to a fixing plate, the inner side of the fixing plate is fixedly connected to a limiting plate, the bottom end of the limiting plate is provided with a clamping groove located on the inner side of the fixing plate, and quartz glass is provided on the inner side of the clamping groove.

[0007] Preferably, the inner sides of the second limiting groove and the third limiting groove are both provided with limiting blocks, and the inner side of the first limiting groove is snap-connected with a connecting ring.

[0008] Preferably, a lamp board located above the quartz glass is snap-connected to the inner side of the limiting plate, and a symmetrically arranged wiring harness is fixedly connected above the lamp board.

[0009] Preferably, there are several auxiliary blocks, which are evenly arranged on the surface of the nut.

[0010] Preferably, the connecting ring is in the shape of a circular ring, and the outer side of the connecting ring is in contact with the first limiting groove.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, by providing components such as a nut, a connecting ring, a limiting block, a waterproof rubber ring, a first limiting groove, a second limiting groove, a third limiting groove, a main body shell, a fixing plate, a limiting plate, a locking groove and a quartz glass, the nut is first taken above the waterproof rubber ring, the limiting block is aligned with the second limiting groove and locked in, and the connecting ring will also enter the first limiting groove at this time. When the connecting ring reaches the bottom, the nut is rotated, and the limiting block is driven to enter the third limiting groove through the nut and the connecting ring, and rotated in the third limiting groove, which greatly improves the sealing effect between the nut and the waterproof rubber ring, and the quartz glass is locked in through the locking groove on the inner side of the fixing plate, and then the main body shell quartz glass is wrapped and fixed from the outside as a whole by using the injection molding process. The locking groove can effectively prevent the quartz glass from being displaced and prolong its service life. The in-mold injection molding process is used to fix the quartz glass to the plastic shell, which can effectively improve the module product. Waterproof ability, and reduce the use of organic glue, prevent water leakage after long-term use and organic glue seepage to pollute the water body, and can also reduce the use of silicone sealing rings, improve assembly efficiency, thereby solving the problem that quartz glass is a high-purity SiO2 thin sheet. At present, silicone sealing rings are usually installed between the plastic shell and the quartz glass to achieve the purpose of waterproofing, but this method requires additional silicone sealing rings in the shell and the quartz glass during the installation process, and there are many steps, resulting in low assembly efficiency. In addition, organic glue bonding can also be used, but there is a risk of water leakage, and organic glue is easy to overflow into the water body to cause pollution. Moreover, with the long-term use of the ultraviolet module, ultraviolet rays have an aging effect on the organic glue, causing the quartz glass to fall off, so that there is a great risk of water leakage in the later stage of use, and the connection between the nut and the rubber ring is only a simple fitting connection relationship, and the connection is not tight enough;

[0013] 2. In the utility model, by providing components such as a fixing plate, a limiting plate, a snap-fitting groove, a quartz glass and a lamp board, the quartz glass can be snapped in the snap-fitting groove to quickly determine the center position of the quartz glass that needs to be fixed. After the quartz glass is snapped, the lamp board can be directly snapped into the limiting plate to quickly determine the center position of the lamp board that needs to be fixed. The quartz glass acts as a limiter just below the lamp board, and there is no need to manually measure the center position, thereby solving the problem that when installing the quartz glass and the lamp board, the installation position of the quartz glass and the lamp board cannot be quickly determined, and the center position needs to be measured to determine, which is very troublesome and affects the production efficiency.
