[0002] With the increasing severity of global water pollution, existing water treatment and sterilization technologies face challenges such as the hazards of chemical disinfection byproducts and the inability of physical filtration to completely kill bacteria. Meanwhile, ultraviolet (UV) sterilization is gaining attention due to its advantages such as high efficiency and no chemical residues.

[0003] Existing water treatment sterilization equipment generally employs a flow-through sterilization method. Specifically, ultraviolet lamps are placed near the flow-through pipe, and the ultraviolet light emitted by these lamps irradiates the water flow inside the pipe, sterilizing it. The opening of the flow-through pipe is typically sealed with a cover, and a flow outlet is provided in the cover for water to enter or exit. However, the sealing at the connection between the flow-through pipe and the cover is currently poor, making leakage prone to occur at this point. This is especially true for high-flow-rate water, where the greater impact force exacerbates the leakage.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In one embodiment, reference is made to Figures 1 to 4 As shown, this embodiment provides a water treatment sterilization device, which includes a shell 1, a flow pipe 2, an ultraviolet lamp 3, a cover 4, a first sealing ring 5, and a second sealing ring 6.

[0034] Specifically, the housing 1 has an internal cavity, and an installation port 11 communicating with the cavity is provided at the end of the housing 1. A flow pipe 2 is installed inside the cavity, and a water flow channel 21 is formed inside the flow pipe 2. An opening 22 communicating with the water flow channel 21 is formed at the end of the flow pipe 2. An ultraviolet lamp 3 is installed inside the cavity. The ultraviolet lamp 3 includes a light-emitting part 31 facing the flow pipe 2. The light-emitting part 31 can generate ultraviolet light directed towards the water flow channel 21, using the ultraviolet light to sterilize the water flow within the water flow channel 21. The cover 4 is installed at the mounting port 11. The cover 4 includes an integrally formed main body 41 and an extension 42. The main body 41 is located outside the water flow channel 21, and the extension 42 extends from the main body 41 into the interior of the water flow channel 21. An outlet 43 is also formed inside the cover 4, which passes through the main body 41 and the extension 42 and is connected to the water flow channel 21, used to input or output water into the water flow channel 21. A first sealing ring 5 is disposed between the end face of the opening 22 and the main body 41 of the cover 4, forming an end sealing structure. A second sealing ring 6 is sleeved on the extension 42 of the cover 4 and is located between the circumferential inner wall of the flow pipe 2 and the circumferential outer wall of the extension 42, forming a circumferential sealing structure.

[0035] The first sealing ring 5 and the second sealing ring 6 can achieve a double seal at the connection between the flow pipe 2 and the cover 4, improving the sealing performance at the connection and reducing the probability of leakage. Furthermore, the end sealing structure formed by the first sealing ring 5 can withstand greater water pressure and maintain a stable sealing effect even under high flow conditions, thus improving the stability of the sealing structure at the connection between the flow pipe 2 and the cover 4.

[0036] In one embodiment, reference is made to Figure 7 As shown, in order to prevent external liquids or moisture from entering the interior of the housing 1 and affecting the normal operation of the ultraviolet lamp 3, a sealing gasket 8 is also provided between the housing 1 and the cover 4.

[0037] Furthermore, considering that the UV lamp 3 needs to be connected to an external power source or control circuit via the wire 9, a wire hole 46 is provided in the cover 4 to allow the wire 9 to be introduced from the outside of the housing 1 into the inside of the housing 1 and connected to the UV lamp 3. To ensure the sealing of the wire hole 46, the wire hole 46 is filled with sealant to fill the gap between the hole wall of the wire hole 46 and the wire 9, preventing external liquids or moisture from entering the interior of the housing 1 through the wire hole 46.

[0038] The sealing gasket 8 and the sealant provided in the wire hole 46 can effectively prevent external liquids or moisture from entering the housing 1, ensuring the normal operation of internal components.

[0039] In one embodiment, reference is made to Figure 4 and Figure 5 As shown, in order to improve the sealing effect of the first sealing ring 5 and reduce the distance between the end face of the main body 41 and the end face of the opening 22, a first receiving groove 44 is recessed on the end face of the main body 41 near the extension 42, and the first sealing ring 5 is at least partially disposed in the first receiving groove 44.

[0040] Furthermore, by setting the first receiving groove 44, the first receiving groove 44 can also be used to prevent the first sealing ring 5 from shifting position under high flow conditions, thereby improving the stability of the position of the first sealing ring 5.

[0041] Furthermore, the first sealing ring 5 adopts a conventional sealing ring structure. Considering that the cross-section of most existing sealing ring structures is circular or elliptical, or similar to circular or elliptical, in order to ensure that the first sealing ring 5 fits as closely as possible to the wall of the first receiving groove 44 and avoid gaps between them, the wall of the first receiving groove 44 is arc-shaped and fits against the first sealing ring 5. At the point where the first sealing ring 5 fits against the first receiving groove 44, the shape of the wall of the first receiving groove 44 matches the outline shape of the first sealing ring 5.

[0042] In one embodiment, reference is made to Figure 4 and Figure 5 As shown, in order to improve the sealing effect of the second sealing ring 6 and reduce the distance between the circumferential outer wall of the extension 42 and the circumferential inner wall of the flow pipe 2, a second receiving groove 45 is recessed on the circumferential outer wall of the extension 42, and the second sealing ring 6 is at least partially disposed in the second receiving groove 45.

[0043] Furthermore, by setting the second receiving groove 45, the second receiving groove 45 can also be used to prevent the second sealing ring 6 from shifting position under high flow pressure, thereby improving the stability of the position of the second sealing ring 6.

[0044] Furthermore, the second sealing ring 6 adopts a conventional sealing ring structure. Considering that the cross-section of most existing sealing ring structures is circular or elliptical, or similar to circular or elliptical, in order to ensure that the second sealing ring 6 fits as closely as possible to the groove wall of the second receiving groove 45 and avoid gaps between them, the groove wall of the second receiving groove 45 near the central axis of the cover body 4 is arc-shaped and fits against the second sealing ring 6. At the point where the second sealing ring 6 fits against the second receiving groove 45, the shape of the groove wall of the second receiving groove 45 matches the contour shape of the second sealing ring 6.

[0045] It should be noted that the shapes of the first receiving groove 44 and the second receiving groove 45 in the above embodiments are one design scheme that can be selected in actual application. For those skilled in the art, without departing from the technical principle of this application, adaptive adjustments can be made to the shapes of the first receiving groove 44 and the second receiving groove 45. For example, if the first receiving groove 44 and the second receiving groove 45 are set as rectangular grooves, they should also be considered as the protection scope of this application.

[0046] Considering that the ultraviolet lamp 3 inside the housing 1 generates heat while producing ultraviolet light, in order to improve the heat dissipation efficiency of the housing 1 and quickly transfer the heat generated by the ultraviolet lamp 3 to the outside of the housing 1, in one embodiment, referring to... Figure 6 As shown, heat dissipation fins 12 are protruding on the circumferential outer wall of the housing 1, which improves the heat dissipation efficiency of the housing 1.

[0047] Furthermore, multiple heat dissipation fins 12 are provided and are arranged circumferentially around the housing 1.

[0048] Optionally, the extension direction of the heat dissipation fins 12 is approximately parallel to the extension direction of the water flow channel 21.

[0049] In one embodiment, reference is made to Figures 2 to 4 As shown, the ultraviolet lamp 3 has a plate-like structure, and the ultraviolet lamp 3 is in thermally conductive contact with the inner wall of the housing 1. Thermally conductive contact means that the ultraviolet lamp 3 is in direct contact with the inner wall of the housing 1, or the ultraviolet lamp 3 is in contact with the inner wall of the housing 1 through a thermally conductive material.

[0050] Furthermore, the extension direction of the ultraviolet lamp 3 is approximately parallel to the extension direction of the water flow channel 21. The ultraviolet lamp 3 includes multiple light-emitting parts 31, which are spaced apart along the extension direction of the water flow channel 21, so that the ultraviolet light can irradiate all areas of the water flow channel 21 as much as possible.

[0051] Furthermore, there are two ultraviolet lamps 3, which are arranged around the flow tube 2.

[0052] Optionally, the two UV lamps can be set opposite each other.

[0053] In one embodiment, reference is made to Figures 2 to 4 As shown, the flow tube 2 is made of a transparent material, including but not limited to quartz glass. The water treatment sterilization equipment also includes a reflector 7, which is sleeved on the flow tube 2 and located between the flow tube 2 and the ultraviolet lamp 3. A reflective surface 71 is formed on the inner wall of the reflector 7. When the ultraviolet light emitted by the ultraviolet lamp 3 enters the water flow channel 21 inside the flow tube 2, the ultraviolet light can penetrate the tube wall of the flow tube 2 and irradiate the reflective surface 71 of the reflector 7. The reflective surface 71 can reflect the ultraviolet light to other areas of the water flow channel 21, so that the ultraviolet light can irradiate as much as possible to all areas of the water flow channel 21.

[0054] Furthermore, considering that the light-emitting part 31 on the ultraviolet lamp 3 is located in the circumferential direction of the flow tube 2, in order to avoid the reflector tube 7 blocking the light-emitting part 31, a light-transmitting hole 72 is provided on the peripheral wall of the reflector tube 7. The light-emitting part 31 of the ultraviolet lamp 3 is arranged facing the light-transmitting hole 72, and the ultraviolet light emitted by the light-emitting part 31 is irradiated to the water flow channel 21 through the light-transmitting hole 72.

[0055] Furthermore, multiple light-transmitting openings 72 are provided, and they cooperate with each other in a one-to-one correspondence with multiple light-emitting parts 31.

[0056] In one embodiment, reference is made to Figure 4 As shown, the first sealing ring 5 extends radially between the end face of the reflector 7 and the main body 41 of the cover 4, thereby appropriately increasing the cross-sectional area of ​​the first sealing ring 5 and improving its sealing effect.

[0057] In one embodiment, reference is made to Figures 1 to 3 As shown, the shell wall of the housing 1 has two installation ports 11, the pipe wall of the flow pipe 2 has two openings 22, and there are two covers 4, one of which has a flow port 43 as an inlet and the other has a flow port 43 as an outlet.

[0058] It should be noted that the number and position of the mounting port 11, opening 22 and cover 4 in the above embodiments are one design scheme that can be selected in actual application. For those skilled in the art, adaptive adjustments to the number and position of the mounting port 11, opening 22 and cover 4 without departing from the technical principles of this application should also be considered as the scope of protection of this application.

[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
