Description

Technical Field

[0001] The utility model relates to an ultraviolet sterilization device, which is applicable to the technical field of water purification. Background Art

[0002] As people pay more and more attention to drinking water quality and health issues, traditional drinking water treatment methods have been unable to meet the increasingly stringent water quality requirements. Although chemical disinfection methods are effective, they will cause secondary pollution and residues of organic matter in the water. Ultraviolet sterilization is a physical sterilization method that effectively kills bacteria, viruses, algae and other microorganisms in the water by destroying the nucleic acid structure of microorganisms, avoiding the problem of chemical residues. At the same time, there is no need to add any chemicals, no secondary pollution, and it is safe and reliable.

[0003] Existing ultraviolet sterilization devices are mostly installed on one side of the water device. When drinking water flows into the water device, the water in the water device can be sterilized by ultraviolet sterilization. However, the existing technology has the following defects: the sterilization device mostly uses ultraviolet LEDs. The UVC ultraviolet rays generated by ultraviolet LED sterilization lamps have a short penetration distance in water. The sterilization effect of the water body far from the ultraviolet LED side in the water device is average, which easily leads to incomplete sterilization. Utility Model Content

DETAILED DESCRIPTION

[0053] Embodiment 1: This embodiment provides an ultraviolet sterilization device, including a top cover, a high-light-transmittance barrel, a high-light-transmittance tube, an ultraviolet module, and a barrel-shaped shell.

[0054] In this example, the top cover has a disc-shaped top cover plate, and a first interface tube and a second interface tube are formed on the lower end surface of the top cover plate, wherein the second interface tube is coaxially arranged with the top cover plate, and the outer diameter of the second interface tube is smaller than the diameter of the top cover plate, and two circles of annular grooves are formed on the outer surface of the second interface tube, and a sealing ring is arranged in the annular groove; the outer diameter of the first interface tube is smaller than the inner diameter of the second interface tube, and the first interface tube is arranged in the second interface tube.

[0055] In this embodiment, a water inlet pipe and a water outlet pipe are formed on the upper end surface of the top cover plate, wherein the water inlet pipe corresponds to and is connected to the first interface pipe below, and the water outlet pipe is connected to the area between the second interface pipe and the first interface pipe.

[0056] In this example, the inner diameter of the high-transmittance barrel is slightly larger than the outer diameter of the second interface tube, and the outer diameter is smaller than the diameter of the top cover plate. It is made of high-transmittance quartz, and the barrel wall can transmit ultraviolet rays. The high-transmittance barrel has a water storage chamber for accommodating water medium, and the top of the high-transmittance barrel is an opening connected to the water storage chamber. The high-transmittance barrel is sleeved on the second interface tube through its top opening to achieve connection with the top cover, and the gap between the inner wall of the high-transmittance barrel and the outer wall of the second interface tube is sealed by a sealing ring.

[0057] In this embodiment, after the high light transmittance barrel is connected to the top cover, the water inlet pipe and the water outlet pipe on the top cover are both connected to the water storage cavity in the high light transmittance barrel sleeved on the second interface pipe.

[0058] In this example, the high-transmittance tube is arranged in the water storage cavity of the high-transmittance barrel. The outer diameter of the high-transmittance tube is slightly smaller than the inner diameter of the first interface tube. The tube is made of high-transmittance quartz, and the tube wall can transmit ultraviolet rays. The upper end of the high-transmittance tube is covered with a silicone sleeve and inserted into the first interface tube through the silicone sleeve. The high-transmittance tube is connected to the top cover through the first interface tube and communicated with the water inlet pipe on the top cover. The lower end of the high-transmittance tube extends to the water storage cavity near the bottom.

[0059] In this embodiment, the barrel-shaped shell has a cylindrical shell body and a bottom cover connected to the lower end of the shell body, wherein the outer diameter of the shell body matches the diameter of the top cover plate, and the inner diameter is larger than the outer diameter of the high light transmittance barrel, the shell body is coaxially sleeved on the high light transmittance barrel, the upper end of the shell body is connected to the top cover plate, and the bottom cover at the lower end is located below the high light transmittance barrel. A gasket is provided between the high light transmittance barrel and the bottom cover, and a groove matching the gasket is formed on the upper end surface of the bottom cover.

[0060] In this example, the barrel-shaped outer shell is combined with the top cover to form a protective cover, and easily damaged parts such as the high-transmittance barrel and the high-transmittance tube are placed in the protective cover to avoid damage and extend the service life.

[0061] In this embodiment, the ultraviolet module has at least one lamp board, which is long and strip-shaped and is installed between the outer shell body and the high-light-transmittance barrel. The length direction of the lamp board is parallel to the axial direction of the outer shell body and the lamp board extends from the upper end of the outer shell body to its lower end. At least one LED sterilization lamp that can generate ultraviolet rays is provided on the side of the lamp board facing the high-light-transmittance barrel.

[0062] In this embodiment, an insertion slot adapted to the light board is formed on the inner wall of the shell body, and the insertion slot extends from the upper end of the shell body to the lower end of the shell body, and the insertion slot opening faces the center of the shell body. The light board can be inserted into the insertion slot from the end of the insertion slot to achieve the connection between the light board and the shell body, thereby limiting the movement of the light board in the horizontal direction to avoid shaking.

[0063] In this example, the lower end of the light board is connected to a lower plug-in, and the bottom cover at the bottom of the barrel-shaped shell is provided with a lower plug-in hole that can be adapted to the lower plug-in. The upper end of the light board abuts against the lower end surface of the top cover, and the lower plug-in at the lower end of the light board is inserted into the lower plug-in hole and connected to the bottom cover to limit the movement of the light board in the vertical direction.

[0064] In this embodiment, the lower plug-in passes through the bottom cover via the lower plug-in hole, and a wire can be configured in the lower plug-in for connecting the light board and an external power supply.

[0065] In this example, a reflective layer is provided on the inner wall of the outer shell body, through which the ultraviolet rays generated by the lamp panel can be reflected to the surrounding of the high-transmittance barrel, so that the ultraviolet rays can irradiate every part of the water storage cavity in the high-transmittance barrel without dead angles, thereby enhancing the sterilization efficiency.

[0066] LED germicidal lamps generate heat due to their own power and are prone to overheating and damage under long-term working conditions. Therefore, heat dissipation of LED germicidal lamps is very necessary. Therefore, in this embodiment, the outer shell body and the bottom cover in contact with the lamp board are made of metal materials with good thermal conductivity to play a heat dissipation role and prevent the lamp board from overheating.

[0067] The installation method of the ultraviolet sterilization device in this embodiment includes the following steps: connecting the high-transmittance tube to the top cover, connecting the high-transmittance barrel to the top cover, putting the outer shell body on the high-transmittance barrel and connecting it to the top cover, installing the light panel on the inner wall of the outer shell body, and finally fixing the bottom cover to the lower end of the outer shell body.

[0068] The working principle of this embodiment is as follows: the water to be sterilized enters the ultraviolet sterilization device through the water inlet pipe, flows from the upper end of the high-transmittance tube connected to the water inlet pipe to the lower end of the high-transmittance tube, and flows from the lower end of the high-transmittance tube to the bottom of the high-transmittance barrel, then flows upward from the bottom of the high-transmittance barrel to the top of the high-transmittance barrel, and finally flows out from the water outlet pipe. In the process of the water flowing from the upper end of the high-transmittance tube to the lower end of the high-transmittance tube, the ultraviolet rays outside the high-transmittance barrel sterilize the water inside the high-transmittance tube through the high-transmittance barrel and the high-transmittance tube, and in the process of flowing from the bottom of the high-transmittance barrel to the top of the high-transmittance barrel, the ultraviolet rays outside the high-transmittance barrel sterilize the water inside the high-transmittance barrel through the high-transmittance barrel, thereby enhancing the sterilization efficiency.

[0069] Embodiment 2: The structure of this embodiment is basically the same as that of Embodiment 1, except that in this embodiment the water outlet pipe corresponds to and is connected to the first interface pipe below, and the water inlet pipe is connected to the area between the second interface pipe and the first interface pipe.

[0070] The above embodiments are only used to explain the utility model's concept, rather than to limit the protection of the utility model's rights. Any non-substantial changes to the utility model using this concept should fall within the protection scope of the utility model.
