Description

Technical Field

[0001] This utility model relates to the field of disinfection equipment technology, specifically to an ultraviolet disinfection head suitable for drinking water pipelines. Background Technology

[0002] Drinking water safety is a crucial aspect of safeguarding public health. Ultraviolet (UV) disinfection, as a highly efficient and chemical-residue-free disinfection method, is widely used in the field of drinking water treatment. UV disinfection uses ultraviolet light emitted by UV germicidal lamps to destroy the DNA structure of microorganisms, thereby killing harmful microorganisms such as bacteria and viruses. However, existing UV disinfection equipment for drinking water pipelines still faces some problems that urgently need to be solved in practical applications.

[0003] On the one hand, traditional ultraviolet disinfection devices are insufficient in terms of ultraviolet light utilization. During the irradiation process, some of the ultraviolet light emitted by the UV germicidal lamp directly shines on the inner wall of the pipe, resulting in wasted ultraviolet energy. Furthermore, due to the absorption or scattering of ultraviolet light by the pipe material, dead corners may be created in the disinfection area, affecting the disinfection effect. On the other hand, when used for a long time or when the water flow is slow, the heat generated by the UV germicidal lamp can easily accumulate in the pipe, causing the drinking water temperature to rise. Changes in water temperature may not only affect the user experience, but more importantly, the rise in water temperature provides a suitable environment for microbial reproduction, especially in areas with slow water flow, which can easily lead to bacterial growth and biofilm formation, thereby reducing the disinfection effect and increasing the risk to water quality safety.

[0004] Based on the problems existing in the above-mentioned technologies, there is an urgent need to design a UV disinfection head suitable for drinking water pipelines that can improve UV utilization and effectively dissipate heat, so as to solve the shortcomings of existing equipment in terms of disinfection effect and heat dissipation performance.

[0016] (III) Beneficial Effects

[0017] This utility model provides a UV disinfection head suitable for drinking water pipelines, which has the following beneficial effects:

[0018] 1. This UV disinfection head for drinking water pipes, through the combined use of a reflector and a UV germicidal lamp, allows the UV germicidal lamp to disinfect the water source during operation.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 4 This utility model embodiment provides a disinfection head for use in scenarios where drinking water is disinfected while flowing through pipes. This embodiment improves the structure of the disinfection head to achieve high efficiency and faster heat dissipation. Specifically, taking the disinfection of drinking water pipes as an example, as a preferred solution in this embodiment, the disinfection head is a UV disinfection head suitable for drinking water pipes, capable of thoroughly sterilizing the drinking water with UV light while avoiding significant temperature fluctuations.

[0027] Please see Figures 1 to 4 This utility model provides a technical solution: an ultraviolet disinfection head suitable for drinking water pipelines, which is used in scenarios where drinking water is disinfected while flowing in pipelines.

[0028] It includes a drainage tube 1, a reflector 2 inserted into the inner wall of the drainage tube 1, multiple heat dissipation rings 7 fixedly connected to the outer surface of the drainage tube 1, a mounting base 8 threadedly connected to the other end of the drainage tube 1, a positioning cylinder 9 fixedly connected to the outer surface of the mounting base 8, a fixing base 11 inserted into the inner wall of the mounting base 8, and an ultraviolet germicidal lamp 12 fixedly inserted into the inner wall of the fixing base 11.

[0029] In this embodiment, the drainage pipe 1 serves as the main pipe of the entire disinfection head, guiding drinking water through the disinfection area, providing a channel for water flow, and supporting the internal reflector 2 and external heat dissipation structure. Its smooth inner wall design reduces water flow resistance, ensuring uniform water flow through the ultraviolet disinfection area. Simultaneously, it provides an installation base for the reflector 2 and the ultraviolet germicidal lamp 12. The reflector 2, inserted into the inner wall of the drainage pipe 1, is made of highly reflective material to reflect the ultraviolet rays emitted by the ultraviolet germicidal lamp 12. By reflecting ultraviolet rays, it reduces energy waste caused by direct light irradiation of the inner wall of the pipe, eliminates disinfection dead zones, and allows ultraviolet rays to penetrate the water flow multiple times, improving sterilization efficiency and ensuring comprehensive disinfection of drinking water. The heat dissipation ring 7 is fixedly connected to the outer surface of the drainage pipe 1, increasing the heat dissipation area. When the ultraviolet germicidal lamp 12 operates for a long time or the water flow is slow, it quickly dissipates the heat accumulated inside the drainage pipe 1, preventing water temperature rise and avoiding providing a suitable environment for microbial growth, thus maintaining water quality safety. The mounting base 8 is threaded to one end of the drainage pipe 1, used to fix the mounting structure of the ultraviolet germicidal lamp 12, providing... The system provides support and positioning, and features a threaded connection for easy detachable installation, facilitating maintenance and replacement of the UV germicidal lamp 12. It also ensures the coaxiality of the germicidal lamp and the drainage pipe 1, guaranteeing uniform UV coverage of the water flow. The positioning cylinder 9 is fixedly connected to the outer surface of the mounting base 8, with a sealing cylinder 10 inserted into its inner wall. This positioning and constraint of the fixed base 11 ensures accurate axial positioning of the fixed base 11 and the UV germicidal lamp 12, preventing uneven UV irradiation due to installation deviations. It also provides a foundation for the sealing structure. The fixed base 11 is inserted into the inner wall of the mounting base 8, internally fixing the UV germicidal lamp 12, supporting the lamp body and ensuring its stability. The tight insertion of the germicidal lamp prevents it from shaking under water flow impact, ensuring accurate UV emission direction. The sealing structure also prevents water leakage. The UV germicidal lamp 12, a core functional component, emits UV light to destroy the DNA structure of microorganisms, achieving sterilization and disinfection. It effectively kills bacteria, viruses, and other microorganisms in drinking water without chemical residue. Combined with the reflector 2, it enhances UV utilization and ensures effective disinfection.

[0030] In the above embodiments, as a preferred option, a section of the drainage pipe 1 is threadedly connected to a sealing end cap 3, and both sides of the top of the drainage pipe 1 are fixedly connected to connecting pipes 4. The sealing end cap 3 is threadedly connected to one end of the drainage pipe 1 to seal the pipe port and prevent water leakage. It can be disassembled when maintenance or repair is required. Normally, it ensures that the inside of the drainage pipe 1 is sealed and maintains the normal flow path of water. The connecting pipes 4 are fixedly connected to both sides of the top of the drainage pipe 1 as an interface with the external water supply pipeline. They are connected to the external pipe network through the connector 5 and the delivery pipe 6 to realize the inflow and outflow of drinking water and ensure that the disinfection head is integrated into the water supply system.

[0031] In the above embodiments, as a preferred option, the inner wall of the connecting pipe 4 is threaded with a connector 5, and a delivery pipe 6 is fixedly connected to one end of the connector 5. The connector 5 is threaded to the inner wall of the connecting pipe 4, and the delivery pipe 6 is fixed to one end of the connector 5 to form a water flow channel, which facilitates quick connection with external pipes, ensures water flow sealing, and realizes the docking of drinking water delivery and disinfection processes.

[0032] In the above embodiments, as a preferred option, a sealing cylinder 10 is inserted into the inner wall of the positioning cylinder 9. The inner wall of the sealing cylinder 10 is sleeved with the outer surface of the fixing seat 11. By inserting the sealing cylinder 10 into the inner wall of the positioning cylinder 9 and sleeved with the outer surface of the fixing seat 11, a sealing structure is formed, which isolates the gap between the fixing seat 11 and the positioning cylinder 9, prevents water from seeping into the interior of the mounting seat 8, and protects the electrical components.

[0033] In the above embodiments, as a preferred option, the end of the ultraviolet germicidal lamp 12 is fixedly connected to a terminal block 13, and a sealing gasket 14 is sleeved on the outer surface of the fixing base 11. The terminal block 13 is fixed to the end of the ultraviolet germicidal lamp 12, connecting the external power supply and the lamp body to transmit electrical energy, ensuring that the ultraviolet germicidal lamp 12 receives a stable power supply and maintains normal working condition. Its insulation design prevents the risk of leakage.

[0034] In the above embodiment, as a preferred solution, the outer surface of the positioning cylinder 9 is threaded with a sealing cap 15. The inner wall of the sealing cap 15 abuts against the outer wall of the sealing gasket 14. The sealing gasket 14 is sleeved on the outer surface of the fixing seat 11 and located between the mounting seat 8 and the sealing cap 15. The sealing cap 15 forms an elastic seal through its abutting action, preventing water from leaking from the connection between the mounting seat 8 and the fixing seat 11, thus ensuring the waterproofness of the device. The sealing cap 15 is threaded to the outer surface of the positioning cylinder 9, and its inner wall abuts against the sealing gasket 14. The sealing gasket 14 is compressed by the thread tightening force, enhancing the sealing effect and fixing the position of the fixing seat 11 to prevent it from loosening.

[0035] In the above embodiment, as a preferred solution, a socket 16 is sleeved on the outer surface of the terminal block 13, and a wire 17 is fixedly connected to the end of the socket 16. The socket 16 is sleeved on the outer surface of the terminal block 13 through the connection of the socket 16 and the wire 17. The wire 17 connects the socket 16 to the external power supply, realizing the electrical connection of the ultraviolet germicidal lamp 12. The wire 17 transmits electrical energy. The tight fit between the socket 16 and the terminal block 13 ensures stable circuit conduction and also has a waterproof design.

[0036] In this invention, the working steps of the device are as follows:

[0037] First, connect the two delivery pipes 6 to the inlet pipe and the outlet pipe respectively. At the same time, turn on the ultraviolet germicidal lamp 12 so that drinking water enters from the inlet pipe and is discharged from the outlet pipe. The ultraviolet germicidal lamp 12 disinfects the drinking water, and the reflector 2 reflects the ultraviolet light to improve the sterilization effect. In addition, the heat dissipation ring 7 can dissipate the generated heat, reduce heat residue, and prevent bacterial growth and biofilm formation.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
