Description

Technical Field

[0001] The present invention relates to the field of water sterilization and disinfection, and in particular to a dynamic water sterilization module and water purification equipment. Background Art

[0002] As people's living standards improve, their requirements for drinking water quality are getting higher and higher. At present, the water disinfection product market has introduced ultraviolet LED sterilization methods. For flowing water, the existing device uses deep ultraviolet LED light sources to perform ultraviolet sterilization on water flowing through pipes. The deep ultraviolet LED light source is placed inside the sterilization cavity. When water flows through the sterilization cavity, the ultraviolet light generated by the ultraviolet LED is used to achieve dynamic water sterilization and disinfection. Among them, the use of deep ultraviolet LED lamps as a new type of artificial deep ultraviolet light source for water flow sterilization and disinfection has the advantages of being green and environmentally friendly, having good sterilization effects, and being flexible to use. It has gradually replaced traditional mercury lamps and become an ideal choice.

[0003] However, in actual use, in order to improve the sterilization rate, the LED power is usually increased. Under high power conditions, the working temperature of the LED is too high, which can easily damage the LED, resulting in a short service life of the LED used for over-flow sterilization in the prior art. How to design a sterilization device that improves the utilization rate of deep ultraviolet LED light, improves sterilization efficiency and prolongs the service life of the equipment is an urgent problem to be solved in this field. Summary of the invention

[0007] In one embodiment, a certain space is provided between the upper outer wall of the reflective metal sleeve and the inner wall of the shell, so that a buffer cavity is formed between the upper outer wall of the reflective metal sleeve and the inner wall of the shell, and EVA material is provided in the buffer cavity.

[0008] In one embodiment, the deep ultraviolet light source assembly includes a metal substrate and a deep ultraviolet light source; the metal substrate has a first surface and a second surface relative to each other, and the deep ultraviolet light source is arranged on the first surface of the metal substrate; the metal substrate is arranged above the incident port of the reflective cup structure, with its first surface facing the incident port, and the end face of the incident port is located around the deep ultraviolet light source to form a cooling zone in the sterilization chamber, so that the heat generated by the deep ultraviolet light source is transferred to the reflective metal sleeve through the metal substrate, and the reflective metal sleeve dissipates heat through the cooling zone.

[0009] In one embodiment, the deep ultraviolet light source assembly further includes a reflective metal structure; the reflective metal structure is disposed between the deep ultraviolet light source and the metal substrate, and is used to reflect light emitted by the deep ultraviolet light source.

[0010] In one embodiment, a first opening is provided on the reflective metal structure, and the first opening corresponds to the position of the deep ultraviolet light source, so that the deep ultraviolet light source is exposed from the reflective metal structure through the first opening; a heat-conducting structure is provided at the connection between the deep ultraviolet light source and the metal substrate, and at the connection between the reflective metal structure and the metal substrate.

[0011] In one embodiment, the metal substrate is an aluminum substrate.

[0012] In one embodiment, an end cap is further included; the end cap is disposed on the second surface of the metal substrate.

Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments; the technical features designed in different implementation modes of the present invention described below can be combined with each other as long as they do not conflict with each other; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] In the description of the present invention, it should be noted that all terms used in the present invention (including technical terms and scientific terms) have the same meanings as those generally understood by ordinary technicians in the field to which the present invention belongs, and cannot be understood as limiting the present invention; it should be further understood that the terms used in the present invention should be understood to have the same meanings as these terms in the context of this specification and in the relevant fields, and should not be understood in an idealized or overly formal sense, unless explicitly defined in the present invention.

[0042] The present invention provides Figure 1-9 A dynamic water disinfection module shown in the embodiment includes a deep ultraviolet light source assembly 20 and a sterilization chamber assembly 10; the sterilization chamber assembly 10 includes a reflective metal sleeve 100, a water inlet pipe 210 and a water outlet pipe 220; a metal baffle 120 is provided on the bottom surface of the reflective metal sleeve 100 to form a sterilization chamber 110 inside it, and the water inlet pipe 210 and the water outlet pipe 220 are both connected to the sterilization chamber 110; the inner surface of the reflective metal sleeve 100 is set as a total reflection surface, and a reflective cup structure 130 is provided on the upper inner wall thereof; the cross-sectional width of the reflective cup structure 130 gradually increases from top to bottom, and an incident port 131 is provided at the bottom of the cup at its upper end, and the cup mouth at its lower end is an outlet 132; the deep ultraviolet light source assembly 20 is arranged at the incident port 131, so that the light generated by it is irradiated into the sterilization chamber 110 and reflected back into the sterilization chamber 110 through the reflective metal sleeve 100.

[0043] like Figure 2-6 As shown, the inner surface of the reflective metal sleeve 100 is set as a total reflection surface (including the bottom metal baffle 120 and the inner wall surface of the reflective cup structure 130 are set as total reflection surfaces), and the upper inner wall is provided with a reflective cup structure 130, and the cross-sectional width of the reflective cup structure 130 gradually increases from top to bottom, that is, the cross-sectional width from the bottom of the reflective cup structure 130 to the cup mouth of the reflective cup structure 130 gradually increases, and the upper end of the cup bottom is provided with an opening, that is, an incident port 131, and the lower end of the cup mouth is an outlet port 132;

[0044] During use, water flows into the sterilization chamber 110 through the water inlet pipe 210 and flows out through the water outlet pipe 220. The deep ultraviolet light source assembly 20 arranged at the incident port 131 emits deep ultraviolet light, which is irradiated into the sterilization chamber 110 through the reflective cup structure to sterilize the water. The reflective cup structure 130 and the total reflection surface of the inner surface of the reflective metal sleeve 100 are arranged so that the light emitted by the deep ultraviolet light source assembly 20 is reflected back and forth in the sterilization chamber 110 to sterilize the water, thereby effectively improving the utilization rate of deep ultraviolet light and enhancing the sterilization efficiency and effect.

[0045] It should be noted that the technical means of setting the inner surface of the reflective metal sleeve 100 as a total reflection surface is an existing technology. For example, the inner cavity wall of the aluminum surface of the reflective metal sleeve 100 is polished and then anodized, evaporated with a dielectric film, or electroplated to form a total reflection surface on the inner surface. According to the above design concept, the technology in the art can adopt other existing methods to make the inner surface of the reflective metal sleeve 100 form a total reflection surface, including but not limited to the above solution;

[0046] It should be noted that the reflective cup structure 130 is a prior art, which is a reflector used for long-distance spotlighting, usually in a cup shape, commonly known as a reflective cup. Its mode of action and working principle will not be described in detail herein. In accordance with the common technical terms in this field, the larger opening in the cup-shaped reflective cup structure 130 is called the cup mouth, and the smaller opening is called the cup bottom.

[0047] Preferably, the sterilization chamber assembly 10 also includes a shell 200 sleeved on the outside of the reflective metal sleeve 100; the reflective metal sleeve 100 is provided with a water inlet 140 below the reflective cup structure 130, and a water outlet 150 is provided on the metal baffle 120 on the side away from the water inlet 140; the shell 200 is provided with a water inlet pipe 210 and a water outlet pipe 220, the water inlet pipe 210 is connected to the water inlet 140, the water outlet pipe 220 is connected to the bottom plate of the shell 200, and the bottom plate of the shell 200 is separated from the metal baffle 120 by a certain space, so that water flows into the sterilization chamber 110 through the water inlet pipe 210, and flows out through the water outlet 150, the spacing space between the metal baffle 120 and the shell 200, and the water outlet pipe 220 in sequence.

[0048] On the one hand, the housing 200 is sleeved on the outside of the reflective metal sleeve 100 to protect the internal components, such as the metal substrate 300 and the reflective metal sleeve 100;

[0049] On the other hand, the reflective metal sleeve 100 is provided with a water inlet 140 below the reflective cup structure 130, and a water outlet 150 is provided on the metal baffle 120 at a side away from the water inlet 140, a water inlet pipe 210 on the shell 200 is connected to the water inlet 140, and a water outlet pipe 220 on the shell 200 is connected to the bottom plate of the shell 200; when in use, external water flows in through the water inlet pipe 210 and flows into the sterilization chamber 110 through the water inlet 140, and Then it flows out through the water outlet 150, the space between the metal baffle 120 and the shell 200, and the water outlet pipe 220 in sequence; wherein, the water outlet 150 on the metal baffle 120 is set on the side away from the water inlet 140, and the water inlet 140 is far away from the water outlet 150, the water flow forms turbulence, and the turbulence degree increases, which can increase the water flow path, so that the water flow is fully irradiated by ultraviolet rays, ensuring that the incoming water flow is completely disinfected, thereby improving the sterilization efficiency and sterilization effect.

[0050] Preferably, there is a certain space between the upper outer wall of the reflective metal sleeve 100 and the inner wall of the shell 200, so that a buffer cavity 230 is formed between the upper outer wall of the reflective metal sleeve 100 and the inner wall of the shell 200, and EVA material 231 is provided in the buffer cavity 230.

[0051] like Figure 2-6 As shown, the buffer cavity 230 formed between the upper outer wall of the reflective metal sleeve 100 and the inner wall of the shell 200 is filled with EVA material 231; the EVA material 231 has the characteristic of good elasticity at low temperatures. When in a low temperature state, the water flow in the sterilization chamber 110 is frozen to expand the volume. The elastic EVA material 231 can effectively prevent the sterilization chamber 110 from bursting during low-temperature freezing.

[0052] Preferably, if Figure 1-9 As shown, in this embodiment, the reflective metal sleeve 100 is a cylindrical structure with a cavity inside, and its upper part is a truncated cone structure, so that the upper cavity of the reflective metal sleeve 100 forms a truncated cone cavity, so that the inner wall surface of the upper part of the reflective metal sleeve 100 forms a reflective cup structure 130; the shell 200 is set to be a cylindrical structure adapted to the reflective metal sleeve 100, and a buffer cavity 230 is formed between the outer wall surface of the upper truncated cone structure of the reflective metal sleeve 100 and the inner wall surface of the cylindrical shell 200;

[0053] The shape of the reflective metal sleeve 100 and the housing 200 is set to facilitate the matching installation of the reflective metal sleeve 100 and the housing 200. Figure 2-4As shown, the metal baffle 120 in this embodiment is a circular structure, the water inlet 140 is arranged below the reflective cup structure 130, and the water outlet 150 is arranged on the metal baffle 120 on the side away from the water inlet 140, that is, the horizontal distance between the water inlet 140 and the water outlet 150 is approximately the diameter of the metal baffle 120, and the two are farthest apart in space, so that the dynamic water flow forms turbulence, the turbulence increases and the path grows.

[0054] Preferably, if Figure 1-9 As shown, in this embodiment, the metal substrate 300 is circular in shape, and the quartz plate 700 is circular in shape; the upper part of the reflective metal sleeve 100 is a truncated cone structure, and its incident port 131 is circular. The quartz plate 700 is set to a circular shape to facilitate matching and installation with the reflective metal sleeve 100.

[0055] It should be noted that, in addition to the scheme described in this embodiment, the metal substrate 300 can also be in other shapes such as square, oval, polygon, etc., and the quartz plate 700 can be adjusted according to the shape of the incident port 131 to match the shape of the incident port 131, including but not limited to the scheme described in the above embodiment.

[0056] Preferably, the deep ultraviolet light source assembly 20 includes a metal substrate 300 and a deep ultraviolet light source 400; the metal substrate 300 has a first surface 310 and a second surface 320 relative to each other, and the deep ultraviolet light source 400 is arranged on the first surface 310 of the metal substrate 300; the metal substrate 300 is arranged above the incident port 131 of the reflective cup structure 130, with its first surface 310 facing the incident port 131, and the end face of the incident port 131 is located around the deep ultraviolet light source 400, so as to form a cooling zone in the sterilization chamber 110 of the reflective metal sleeve 100, so that the heat generated by the deep ultraviolet light source 400 is transferred to the reflective metal sleeve 100 through the metal substrate 300, and the reflective metal sleeve 100 dissipates heat through the cooling zone.

[0057] like Figure 2-9 As shown, the deep ultraviolet light source 400 is arranged on the first surface 310 of the metal substrate 300, and is used to emit light; when in use, water flows in from the water inlet pipe 210, flows through the sterilization chamber 110, and is discharged from the water outlet pipe 220. The heat generated by the deep ultraviolet light source 400 is transmitted to the metal substrate 300. Since the first surface 310 of the metal substrate 300 is in contact with the incident port end face 1311, the heat is transferred to the reflective metal sleeve 100 through the metal substrate 300, and the heat is dissipated by the water flow in the cooling zone (i.e., the sterilization chamber 110 filled with water), and the heat is absorbed by water cooling, so that the deep ultraviolet light source 400 maintains a relatively low temperature when working.

[0058] Preferably, the deep ultraviolet light source assembly 20 further includes a reflective metal structure 500 ; the reflective metal structure 500 is disposed between the deep ultraviolet light source 400 and the metal substrate 300 , and is used for reflecting light emitted by the deep ultraviolet light source 400 .

[0059] like Figure 7-9 As shown, the reflective metal structure 500 is located between the deep ultraviolet light source 400 and the metal substrate 300, and is used to reflect the deep ultraviolet light reflected back from the inner surface of the reflective metal sleeve 100, so that the light enters the sterilization chamber 110 after being reflected by the reflective metal structure 500 to disinfect the water flow.

[0060] Preferably, a first opening 510 is provided on the reflective metal structure 500, and the first opening 510 corresponds to the position of the deep ultraviolet light source 400, so that the deep ultraviolet light source 400 is exposed from the reflective metal structure 500 through the first opening 510; a heat-conducting structure (shown in the figure) is provided at the connection between the deep ultraviolet light source 400 and the metal substrate 300, and at the connection between the reflective metal structure 500 and the metal substrate 300.

[0061] A thermal conductive structure is used at the connection between the deep ultraviolet light source 400 and the metal substrate 300, and at the connection between the reflective metal structure 500 and the metal substrate 300, which can not only strengthen the connection between the deep ultraviolet light source 400 and the metal substrate 300, and between the reflective metal structure 500 and the metal substrate 300, but also help to guide the heat generated by the deep ultraviolet light source 400 to the metal substrate 300, thereby enhancing the heat dissipation of the deep ultraviolet light source 400; in addition, the metal substrate 300 is connected to the reflective metal structure 500 via the thermal conductive structure, so that heat can be transferred from the first surface 310 of the metal substrate 300 to the reflective metal structure 500, thereby extracting the heat.

[0062] The heat-conducting structure may be made of materials such as thermal conductive silicone grease or solder paste, that is, the metal substrate 300 is connected to the reflective metal structure 500 and the deep ultraviolet light source 400 by welding or thermal conductive silicone grease. Preferably, the first surface 310141 of the metal substrate 300 is preliminarily subjected to an operation of removing paint and insulating heat-conducting layers to expose the metal material, and the exposed metal material is connected to the reflective metal structure 500 by welding or thermal conductive silicone grease.

[0063] It should be noted that the heat-conducting structure described in this embodiment is made of materials such as thermal grease or solder paste. According to the above design concept, those skilled in the art can also use heat-conducting structures made of other existing heat-conducting materials, including but not limited to the above scheme.

[0064] Preferably, the metal substrate 300 is an aluminum substrate.

[0065] The aluminum substrate has high structural strength and excellent electrical conductivity, thermal conductivity and corrosion resistance. It should be noted that the aluminum substrate is used as a preferred embodiment in this embodiment. According to the above design concept, those skilled in the art can also use other metal materials with good thermal conductivity, including but not limited to the above aluminum substrate.

[0066] Preferably, an end cover 600 is further included; the end cover 600 is disposed on the second surface 320 of the metal substrate 300 .

[0067] The end cover 600 is disposed on the second surface 320 of the metal substrate 300 and connected to the housing 200 to protect the internal components.

[0068] Preferably, a quartz plate 700 is further included on the incident port 131 ; the quartz plate 700 is disposed below the deep ultraviolet light source assembly 20 to block the sterilization chamber 110 and the deep ultraviolet light source assembly 20 .

[0069] The quartz plate 700 is provided to block the sterilization chamber 110 and the deep ultraviolet light source assembly 20 , which can ensure that the deep ultraviolet light can be smoothly irradiated into the sterilization chamber 110 and protect the deep ultraviolet light source assembly 20 inside.

[0070] Preferably, the deep ultraviolet light source assembly 20 includes a plurality of deep ultraviolet light sources 400, which are arranged in a rectangular array on the first surface 310 of the metal substrate 300.

[0071] like Figure 7-9 As shown, in this embodiment, there are four deep ultraviolet light sources 400, which are arranged in a rectangular array on the first surface 310 of the metal substrate 300 to provide a better disinfection effect;

[0072] It should be noted that, based on the above design concept, those skilled in the art may adopt other numbers of deep ultraviolet light sources 400, including but not limited to the solutions described in the embodiments.

[0073] In summary, compared with the prior art, the dynamic water disinfection module provided by the present invention has the following excellent effects:

[0074] 1. Through the total reflection surface setting of the inner surface of the reflective metal sleeve 100 and the upper reflective cup structure 130, the light emitted by the deep ultraviolet light source assembly 20 is continuously reflected in the sterilization chamber 110 to disinfect the water flow, so that the water flow is fully irradiated by ultraviolet rays, ensuring that the incoming water flow is completely disinfected, effectively improving the utilization rate of deep ultraviolet light and enhancing the sterilization efficiency and effect.

[0075] 2. By setting the water outlet 150 on the metal baffle 120 at a side away from the water inlet 140, the water inlet 140 is far away from the water outlet 150, and the water flow forms turbulence, the turbulence degree increases, so that the water flow path can be increased, so that the water flow is fully irradiated by ultraviolet rays, ensuring that the inflowing water flow is completely sterilized, thereby improving the sterilization efficiency and sterilization effect;

[0076] 3. The buffer cavity 230 formed between the upper outer wall of the reflective metal sleeve 100 and the inner wall of the shell 200 is filled with EVA material 231. Under low temperature conditions, the EVA material 231 with good elasticity at low temperatures can effectively prevent the sterilization chamber 110 from bursting during low-temperature freezing.

[0077] 4. The metal substrate 300 on the deep ultraviolet light source assembly 20 cooperates with the metal reflective sleeve to form a cooling zone in the sterilization chamber 110 of the reflective metal sleeve 100 which is filled with water. The heat generated by the deep ultraviolet light source 400 is transferred to the reflective metal sleeve 100 through the metal substrate 300, and dissipated by the water flow in the cooling zone. The heat is absorbed by water cooling, so that the deep ultraviolet light source 400 maintains a low temperature during operation, thereby increasing the service life of the ultraviolet light source.

[0078] In addition, those skilled in the art should understand that, although there are many problems in the prior art, each embodiment or technical solution of the present invention can be improved in only one or several aspects, without having to solve all the technical problems listed in the prior art or background technology at the same time.
