A disinfection device for domestic water

Abstract

This utility model discloses a disinfection device for domestic water, relating to the technical field of domestic water disinfection devices. It includes an outer shell assembly composed of a stainless steel cylinder, a flange, and a connecting channel. Disinfection components are disposed on the inner and outer sides of the stainless steel cylinder, and these components are used to disinfect the water flowing through the inner side of the stainless steel cylinder. This utility model achieves water flow along a spiral trajectory and is disinfected by ultraviolet radiation by setting up the disinfection components. Compared to traditional straight flow, the spiral flow extends the water flow distance, increasing the exposure time for microorganisms. Furthermore, the centrifugal force generated by the swirling flow causes repeated exchange of water from the pipe wall to the center, allowing microorganisms to be more evenly exposed to the high-intensity ultraviolet radiation area. This reduces radiation dead zones, extends exposure time, and increases the probability of microorganisms contacting ultraviolet radiation, further improving the disinfection effect and power of domestic water.

Description

Technical Field

[0001] This utility model relates to the technical field of disinfection devices for domestic water, specifically a disinfection device for domestic water. Background Technology

[0002] Domestic water disinfection devices are key equipment for ensuring drinking water safety and preventing the spread of waterborne diseases. They kill pathogenic microorganisms such as bacteria, viruses, and parasites in the water through various physical or chemical methods. Pipeline ultraviolet sterilizers are physical disinfection devices that use UVC ultraviolet light (wavelength 254nm) to instantly kill bacteria, viruses and other microorganisms in the water flowing through the pipe. Its core advantages are that it does not add chemicals, does not change the water quality and has no harmful byproducts, and is widely used in the field of domestic water disinfection.

[0003] In ordinary pipeline-type ultraviolet sterilizers, the water flow is usually "piston flow" (laminar flow), with a fast flow velocity in the center of the pipe and a slow flow velocity at the edge. This results in a short exposure time for microorganisms in the center and a longer exposure time at the edge, but the edge may be blocked. Some water flow may not fully contact the ultraviolet radiation area, resulting in disinfection dead zones. Based on this, a disinfection device for domestic water is provided. Utility Model Content

[0004] The purpose of this invention is to provide a disinfection device for domestic water in order to solve the problems mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a disinfection device for domestic water, comprising an outer shell assembly consisting of a stainless steel cylinder, a flange, and a connecting channel. The flange is symmetrically fixed at both ends of the stainless steel cylinder, and the connecting channel is symmetrically fixed at both ends of one side of the stainless steel cylinder and communicates with the inner cavity of the stainless steel cylinder. Disinfection components are provided on the inner and outer sides of the stainless steel cylinder, and the disinfection components are used to disinfect the water flowing through the inner side of the stainless steel cylinder. The disinfection assembly includes an end face disc, a water flow channel, a quartz sleeve, a spiral guide vane, a positioning ring, an ultraviolet lamp, a controller, and a power cord; Two end face discs are provided, and the water flow channel is fixed between the two end face discs. The end face discs and the water flow channel are distributed inside the stainless steel cylinder, and the two ends of the water flow channel are connected to the inside of the stainless steel cylinder. The ports of the two connecting channels are located at the ends of the two end face discs that are far apart from each other. The spiral guide vane is fixed to the outside of the quartz sleeve. The quartz sleeve extends from one end of a flange through the flange, the stainless steel cylinder, and the quartz sleeve to the outside of the other flange. The outside of the spiral guide vane is in contact with the inner wall of the water flow channel. The ultraviolet lamp is installed inside the quartz sleeve, and the controller is installed on the top of the outer wall of the stainless steel cylinder. The controller is electrically connected to the terminal of the ultraviolet lamp through a power cord, and controls the operation of the ultraviolet lamp through the controller. Water entering the stainless steel cylinder through a connecting channel flows through a spiral channel composed of spiral guide vanes and water flow channels to another connecting channel to achieve spiral flow of water, and is sterilized and disinfected by ultraviolet light emitted by ultraviolet lamps.

[0006] As a further embodiment of this utility model: the number of water flow channels is provided in multiple ways, one of the water flow channels is located at the center of the end face disk, and the other water flow channels are distributed in a ring with the center of the end face disk as the center.

[0010] Compared with the prior art, the beneficial effects of this utility model are: By setting up disinfection components, water flows along a spiral trajectory and is disinfected by ultraviolet light. Compared with the traditional straight flow, the spiral flow extends the distance the water travels, increasing the exposure time of microorganisms. In addition, the centrifugal force generated by the swirling flow causes the water to repeatedly exchange from the pipe wall to the center, allowing microorganisms to be exposed to the high-intensity ultraviolet area more evenly. In this way, the effects of reducing radiation dead zones, extending exposure time, and increasing the probability of microorganisms coming into contact with ultraviolet light are achieved, further improving the disinfection effect and power of domestic water.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-3 In this embodiment of the present invention, a disinfection device for domestic water includes an outer shell assembly 1 assembled from a stainless steel cylinder 101, a flange 102, and a connecting channel 103. The flange 102 is symmetrically fixed at both ends of the stainless steel cylinder 101, and the connecting channel 103 is symmetrically fixed at both ends of one side of the stainless steel cylinder 101 and communicates with the inner cavity of the stainless steel cylinder 101. A disinfection component 2 is provided on the inner and outer sides of the stainless steel cylinder 101. The disinfection component 2 is used to disinfect the water flowing through the inner side of the stainless steel cylinder 101. The disinfection component 2 includes an end face disc 201, a water flow channel 202, a quartz sleeve 205, a spiral guide vane 206, a positioning ring 207, an ultraviolet lamp tube 208, a controller 209, and a power cord 210. Two end face discs 201 are provided. The water flow channel 202 is fixed between the two end face discs 201. The end face discs 201 and the water flow channel 202 are distributed inside the stainless steel cylinder 101 and the two ends of the water flow channel 202 are connected to the inside of the stainless steel cylinder 101. The ports of the two connecting channels 103 are located at the ends of the two end face discs 201 that are far apart from each other. The spiral guide vane 206 is fixed to the outside of the quartz sleeve 205. The quartz sleeve 205 extends from one end of the flange 102 through the flange 102, the stainless steel cylinder 101, and the quartz sleeve 205 to the outside of the other flange 102. The outside of the spiral guide vane 206 is in contact with the inner wall of the water flow channel 202. The ultraviolet lamp 208 is installed inside the quartz sleeve 205, and the controller 209 is installed on the top of the outer wall of the stainless steel cylinder 101. The controller 209 is electrically connected to the terminal of the ultraviolet lamp 208 through the power cord 210, and controls the operation of the ultraviolet lamp 208 through the controller 209. Water entering the stainless steel cylinder 101 through a connecting channel 103 flows through a spiral channel composed of a spiral guide plate 206 and a water flow channel 202 to another connecting channel 103, thereby realizing the spiral flow of water and being sterilized and disinfected by ultraviolet light emitted by the ultraviolet lamp tube 208. There are multiple water flow channels 202. One water flow channel 202 is located at the center of the end face disk 201. The other water flow channels 202 are distributed in a ring around the center of the end face disk 201. The number and position of the quartz sleeve 205 and the spiral guide vane 206 correspond one-to-one with the number and position of the water flow channels 202. The end face disc 201, water flow channel 202, quartz sleeve 205, and spiral guide vane 206 are all made of transparent material.

[0015] In this embodiment, the operating principle of this device is as follows: Water flows into the inside of the stainless steel cylinder 101 through a connecting channel 103. Then, the water flows through multiple water channels 202 and flows to the other side of the inside of the stainless steel cylinder 101. After that, the multiple water flows converge on the other side of the stainless steel cylinder 101 and flow out through another connecting channel 103. During this process, when the water flows in the water flow channel 202, it is guided by the spiral guide plate 206 to achieve spiral trajectory flow. At the same time, the ultraviolet lamp tube 208 is started by the controller 209. The ultraviolet lamp tube 208 emits UVC. The UVC penetrates the quartz sleeve 295 and irradiates the water flow, thereby destroying the DNA / RNA of microorganisms, causing them to lose their reproductive ability (inactivation), thus achieving the effect of sterilization and disinfection. The combination of the above-mentioned components enables the water to flow in a spiral trajectory, extending the distance the water travels and increasing the exposure time of microorganisms. In addition, the swirling flow generates centrifugal force, causing the water to repeatedly exchange from the pipe wall to the center, allowing microorganisms to be exposed to the high-intensity ultraviolet radiation area more evenly. This reduces radiation dead zones, extends exposure time, and increases the probability of microorganisms coming into contact with ultraviolet radiation, further improving the disinfection effect and power of domestic water.

[0016] Please refer to this carefully. Figures 2-3 Multiple annularly distributed connecting rods 203 are symmetrically fixed at the ends of the two end face disks 201 that are far apart from each other. A limiting ring 204 is fixed at the end of the connecting rod 203 that is far away from the end face disk 201. The limiting ring 204 is in contact with the end face of the flange 102. A positioning ring 207 is fixed on the outer side of the contact position between the quartz sleeve 205 and the flange 102, and a sealing element that fits tightly against the flange 102 is provided on the end face of the positioning ring 207. A sealing element is provided at the contact point between the outer side of the end face disc 201 and the inner wall of the stainless steel cylinder 101.

[0017] In this embodiment: the limiting ring 204 can fix the end face disc 201 and the water flow channel 202 in the center position inside the stainless steel cylinder 101, ensuring that the two connecting channels 103 are connected to the water flow channel 202. The positioning ring 207 is designed to fix the position of the quartz sleeve 205 inside the stainless steel cylinder 101. In addition, the sealing elements on the end face of the positioning ring 207 and the outer side of the end face disc 201 are used to ensure a good seal inside the stainless steel cylinder 101, so that the water flows according to the set trajectory.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
