Description

Technical Field

[0001] This utility model relates to the field of pure water treatment technology, and in particular to a pure water treatment device with ultraviolet sterilization and filtration. Background Technology

[0002] Water treatment devices employ a multi-stage filtration and ultraviolet sterilization structure. Typically, a reverse osmosis membrane or ultrafiltration membrane serves as the final stage of filtration, removing bacteria, viruses, and other microorganisms from tap water. Ultraviolet sterilization is performed after the filtration membrane for further sterilization. However, in this structure, the bacteria and other microorganisms remaining in the filtration membrane still possess a certain degree of activity, easily damaging the membrane and reducing its lifespan. Furthermore, frequent chemical flushing or replacement of the membrane is required, making the operation complex and costly. In addition, residual water often remains at the outlet during daily use. Because the outlet is constantly exposed to air, this residual water is prone to bacterial growth, and direct consumption could even affect the user's health.

[0003] Existing technology CN207774978U discloses a pre-filter water treatment device with ultraviolet (UV) sterilization, comprising a filter assembly, a UV sterilization assembly, and a reverse osmosis filter connected sequentially along the water flow direction via pipes. A booster pump is installed on the pipes between the UV sterilization assembly and the reverse osmosis filter. The bottom of the reverse osmosis filter has a wastewater outlet, and the outlet of the reverse osmosis filter has a pure water outlet pipe. A first UV lamp is vertically installed on the inner wall of the pure water outlet pipe near the pipe opening. By placing the UV sterilization device in front of the filter membrane, microorganisms in the water are sterilized, greatly improving the service life of the filter membrane. Furthermore, by installing the UV sterilization device at the outlet, residual water at the outlet is sterilized, resulting in good water treatment performance, safe and healthy drinking water, and strong practicality.

[0004] However, in the above technologies, the water flow speed affects the irradiation time and uniformity of the ultraviolet lamp on the water, and vertical ultraviolet lamps can usually only irradiate in one direction, so it is necessary to ensure that the water flow direction is consistent with the irradiation direction of the ultraviolet lamp. In contrast, circular ultraviolet lamps can emit a ring-shaped light spot, with a relatively large irradiation area, which is more conducive to the comprehensive sterilization of water in the pipe. Utility Model Content

[0005] The purpose of this invention is to provide an ultraviolet sterilization and filtration pure water treatment device, which solves the problems of uneven sterilization effect of existing vertical ultraviolet lamps on water flow and inconvenient installation.

[0006] To achieve the above objectives, this utility model provides an ultraviolet sterilization and filtration pure water treatment device, including a filter assembly, an ultraviolet sterilization assembly, and a reverse osmosis water filter. The filter assembly is connected sequentially along the water flow direction through pipes. The ultraviolet sterilization assembly is located between the filter assembly and the reverse osmosis water filter. The outlet end of the reverse osmosis water filter is provided with a pure water outlet pipe.

[0007] It also includes a pure water sterilization component;

[0008] The pure water sterilization assembly includes a sterilization outlet tube, a connecting screw tube, two annular ultraviolet lamps, a separator, and a sealing outlet component. The sterilization outlet tube is fixedly connected to the connecting screw tube and is located at the bottom of the connecting screw tube. The connecting screw tube is threadedly connected to the pure water outlet tube and spirally extends into the outlet end of the pure water outlet tube. The two annular ultraviolet lamps are located in the inner cavity of the sterilization outlet tube. The separator is located in the inner cavity of the sterilization outlet tube and is located between the two annular ultraviolet lamps. The sealing outlet component is threadedly connected to the sterilization outlet tube and is located at the bottom of the sterilization outlet tube.

[0009] The separator includes two rings and two vertical plates, with the two rings fixedly connected to the two ends of the two vertical plates; the two vertical plates are located between the two rings.

[0010] The sealed water outlet component includes a sealing connection cover, a water outlet pipe, and a valve. The sealing connection cover is threadedly connected to the water outlet sterilization pipe and is located at the bottom of the water outlet sterilization pipe. The water outlet pipe is fixedly connected to the sealing connection cover and is located at the bottom of the sealing connection cover. The valve is connected to the water outlet pipe.

[0011] The water outlet sterilization pipe has a sealing thread, which is located at the lower end of the inner side wall of the water outlet sterilization pipe and engages with the thread on the sealing connection cover; the sealing water outlet component also includes a rubber ring, which is fitted onto the sealing connection cover.

[0012] The pure water outlet pipe has a connecting thread, which is located at the lower end of the inner wall of the pure water outlet pipe and engages with the thread on the outer side of the connecting screw tube; the pure water outlet sterilization component also includes a sealing gasket, which is sleeved on the outer side of the connecting screw tube.

[0013] This utility model discloses an ultraviolet sterilization and filtration pure water treatment device. With the connecting screw tube facing downwards, one annular ultraviolet lamp is placed into the outlet sterilization tube, followed by the placement of a separator into the outlet sterilization tube. Then, another annular ultraviolet lamp is placed on the separator. Finally, the outlet sterilization tube is sealed by a sealing outlet component. After the pure water outlet sterilization assembly is assembled, it is threadedly locked to the pure water outlet tube via the connecting screw tube, thus achieving the installation and connection of the pure water outlet sterilization assembly. Pure water is injected into the outlet sterilization tube through the pure water outlet tube, sterilized by the two annular ultraviolet lamps within the outlet sterilization tube, and then output through the sealing outlet component. This allows for convenient installation and disassembly of the pure water outlet sterilization assembly, and provides a relatively large irradiation area, which is more conducive to comprehensive sterilization of the water flow.

[0021] This utility model discloses an ultraviolet sterilization and filtration pure water treatment device, comprising a filter assembly 101, an ultraviolet sterilization assembly 102, a reverse osmosis water filter 103, and a pure water outlet sterilization assembly.

The outlet sterilization pipe 105 has a sealing thread 113. The sealing outlet component also includes a rubber ring 114. The pure water outlet pipe 104 has a connecting thread 115. The pure water outlet sterilization assembly also includes a sealing gasket 116. The aforementioned solution solves the problems of uneven sterilization effect of existing vertical ultraviolet lamps on water flow and inconvenient installation. It is understood that the aforementioned solution is more conducive to the comprehensive sterilization of water flow by the easy installation and disassembly of the pure water output sterilization component and the relatively large irradiation area.

[0022] In this embodiment, the filter assembly 101 is connected sequentially through pipes along the water flow direction. The ultraviolet sterilization assembly 102 is located between the filter assembly 101 and the reverse osmosis water filter 103. The outlet end of the reverse osmosis water filter 103 is provided with a pure water outlet pipe 104. The filtration assembly 101 includes a quartz water filter, an activated carbon water filter, and an ion exchange resin water filter connected sequentially through pipes along the water flow direction. The ultraviolet sterilization assembly 102 includes an ultraviolet lamp and a cotton filter cartridge. The ultraviolet lamp is located on the inner top wall of the cotton filter cartridge. A water circulation assembly is provided outside the cotton filter cartridge. The water circulation assembly includes a circulation outlet at the bottom of the cotton filter cartridge and a circulation inlet at the top of one side of the cotton filter cartridge. The circulation outlet is connected to the circulation inlet through a circulation pump and pipes. By placing the ultraviolet sterilization assembly 102 in front of the reverse osmosis water filter 103, microorganisms in the water are sterilized, which greatly improves the service life of the filter membrane of the reverse osmosis water filter 103.

[0023] The water outlet sterilization pipe 105 is fixedly connected to the connecting screw pipe 106 and located at the bottom of the connecting screw pipe 106. The connecting screw pipe 106 is threadedly connected to the pure water outlet pipe 104 and spirally extends into the outlet end of the pure water outlet pipe 104. Two annular ultraviolet lamps 107 are located in the inner cavity of the water outlet sterilization pipe 105. The separator is located in the inner cavity of the water outlet sterilization pipe 105 and between the two annular ultraviolet lamps 107. The sealing water outlet component is threadedly connected to the water outlet sterilization pipe 105 and located at the bottom of the water outlet sterilization pipe 105. The connecting thread 115 is provided at the lower end of the inner wall of the pure water outlet pipe 104 and engages with the thread on the outer side of the connecting screw pipe 106. The sealing gasket 116 is sleeved on the outer side of the connecting screw pipe 106. The top of the water outlet sterilization pipe 105 is provided with the connecting screw pipe 106. The outer side of the connecting screw pipe 106 is threaded, which mates with the connecting thread 115 provided on the inner side of the outlet end of the pure water outlet pipe 104. The water outlet sterilization pipe 105 is installed by screwing the connecting screw pipe 106 onto the pure water outlet pipe 104. The bottom of the outer wall of the connecting screw pipe 106 is fitted with the sealing gasket 116, which increases the connection between the connecting screw pipe 105 and the pure water outlet pipe 104. The connection sealing of the pure water outlet pipe 104 is described above. An annular ultraviolet lamp 107 is provided at the upper end of the inner cavity of the water outlet sterilization pipe 105. A separator is provided at the bottom of the annular ultraviolet lamp 107, and another annular ultraviolet lamp 107 is provided at the lower end of the separator. The installation positions of the two annular ultraviolet lamps 107 are controlled by the separator. The two annular ultraviolet lamps 107 can emit annular light spots with a relatively large irradiation area, which is beneficial for the water flow in the water outlet sterilization pipe 105. For comprehensive sterilization, the bottom of the water outlet sterilization pipe 105 is detachably sealed by the sealing water outlet component. This not only seals the bottom of the water outlet sterilization pipe 105 for the installation of the annular ultraviolet lamp 107, but also controls the output of pure water. Therefore, when installing the pure water outlet sterilization component, with the connecting screw 106 facing downwards, one of the annular ultraviolet lamps 107 is placed into the water outlet sterilization pipe 105, then the separator is placed into the water outlet sterilization pipe 105, and then the other annular ultraviolet lamp is placed in. 107 is placed on the separator, and finally the water outlet sterilization pipe 105 is sealed by the sealing water outlet component. After the pure water outlet sterilization component is assembled, it is connected to the pure water outlet pipe 104 by the connecting screw pipe 106 through the threaded lock, so as to realize the installation and connection of the pure water outlet sterilization component. Pure water is injected into the water outlet sterilization pipe 105 through the pure water outlet pipe 104. After being sterilized by the two annular ultraviolet lamps 107 in the water outlet sterilization pipe 105, it is output through the sealing water outlet component.

[0024] Secondly, the two circular rings 108 are fixedly connected to the two ends of the two vertical plates 109; the two vertical plates 109 are located between the two circular rings 108. The outer diameter of the two circular rings 108 is the same as the inner diameter of the water outlet sterilization pipe 105, and the inner diameter of the two circular rings 108 is larger than the inner diameter of the two annular ultraviolet lamps 107. Two vertical plates 109 are symmetrically welded between the two circular rings 108. The two vertical plates 109 have an arc-shaped structure and cooperate with the inner sidewall of the water outlet sterilization pipe 105. The two circular rings 108 and the two vertical plates 109 are welded together to form the separator, which restricts the installation interval of the two annular ultraviolet lamps 107, so that the two annular ultraviolet lamps 107 emit annular light spots to irradiate the entire water outlet sterilization pipe 105, thereby improving the sterilization effect on the water flow.

[0025] Meanwhile, the sealing connection cap 110 is threadedly connected to the water outlet sterilization pipe 105 and located at the bottom of the water outlet sterilization pipe 105; the water outlet pipe 111 is fixedly connected to the sealing connection cap 110 and located at the bottom of the sealing connection cap 110; the valve 112 is connected to the water outlet pipe 111. The sealing thread 113 is provided at the lower end of the inner side wall of the water outlet sterilization pipe 105 and engages with the thread on the sealing connection cap 110; the rubber ring 114 is sleeved on the sealing connection cap 110. The upper end of the sealing connection cover 110 is an annular structure, and its outer side wall is provided with a sealing thread 113 that mates with the water outlet sterilization pipe 105. This allows the sealing connection cover 110 to be detachably installed on the water outlet sterilization pipe 105. A rubber ring 114 is fitted on the bottom of the annular outer side of the sealing connection cover 110 to further seal and prevent water leakage. The water outlet pipe 111 is inserted through the middle of the bottom of the sealing connection cover 110, through which pure water sterilized by ultraviolet light is output. A valve 112 is provided on the water outlet pipe 111 to close the water outlet pipe 111. Thus, the combination installation and water outlet closure of the pure water outlet sterilization component are realized through the sealing water outlet component.

[0026] When using the ultraviolet sterilization and filtration pure water treatment device of this utility model, with the connecting screw tube 106 facing downwards, one of the annular ultraviolet lamp tubes 107 is placed into the water outlet sterilization tube 105, and then the separator is placed into the water outlet sterilization tube 105. Then, another annular ultraviolet lamp tube 107 is placed on the separator. Finally, the water outlet sterilization tube 105 is sealed by the sealing water outlet component. After the pure water outlet sterilization assembly is assembled, it is threadedly locked to the pure water outlet tube 104 through the connecting screw tube 106, thus realizing the installation and connection of the pure water outlet sterilization assembly. Pure water is injected into the water outlet sterilization tube 105 through the pure water outlet tube 104. After being sterilized by the two annular ultraviolet lamp tubes 107 in the water outlet sterilization tube 105, it is output through the sealing water outlet component. This allows for convenient installation and disassembly of the pure water outlet sterilization assembly, and the relatively large irradiation area is more conducive to comprehensive sterilization of the water flow.
