Description

Technical Field

[0001] This invention relates to the field of ultraviolet sterilization technology, and in particular to a UVC water sterilization device. Background Technology

[0002] In the field of water treatment, ultraviolet (UV) sterilization technology is widely used in drinking water purification, industrial circulating water disinfection, and domestic sewage pretreatment due to its advantages such as no chemical residue, high sterilization efficiency, and ease of operation. Among them, UVC ultraviolet light, with its wavelength characteristics, can destroy the DNA or RNA structure of microorganisms, rendering them unable to reproduce, and has become the mainstream sterilization technology solution.

[0003] Currently available water-based UVC ultraviolet sterilization equipment typically features an integrated design where the UVC lamp is fixedly assembled with the equipment body, including the water flow channel, casing, and connectors, forming an inseparable unit. This type of integrated equipment suffers from the following significant drawbacks in practical applications:

[0004] (1) The replacement operation is complicated and the maintenance efficiency is low: As a consumable component, the UVC lamp has a clear service life limit. When the cumulative working time reaches the rated life, its ultraviolet radiation intensity will significantly decrease and it will not meet the sterilization standard. It must be replaced. However, since the equipment is an integrated structure, the entire sterilization equipment needs to be disassembled from the pipeline system when replacing it. This requires not only professional tools and operators, but also pipeline disconnection and sealing. The disassembly and reassembly process is time-consuming and laborious, which seriously affects the continuous operation of the water treatment system.

[0005] (2) Serious waste of resources and does not conform to the concept of environmental protection. Integrated equipment: When replacing, the entire equipment, including UVC lamp, shell, water flow channel, seals, and fixed bracket, must be discarded. However, except for the UVC lamp, the shell, water flow channel, bracket and other structures of the equipment often still have good mechanical properties and use value. The entire equipment is scrapped only because the core sterilization component fails, resulting in material waste.

[0006] (3) High usage costs: The replacement cost of integrated equipment is the purchase cost of the entire set of equipment, rather than the cost of a single UVC lamp. For long-term users, each replacement requires payment of the cost of the entire set of equipment, which greatly increases the total life cycle cost of the equipment.

[0007] Therefore, this invention proposes a replaceable UVC water sterilization device. By replacing the UVC lamp after the VC lamp reaches the end of its lifespan, the device can easily replace the UVC lamp, reduce waste, and lower costs.

[0008] In summary, existing integrated water flow UVC ultraviolet sterilization equipment has significant shortcomings in terms of ease of maintenance, resource utilization efficiency, and cost control, and cannot meet users' needs for efficient, economical, and environmentally friendly water treatment sterilization solutions.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] The purpose of this invention is to provide a UVC water sterilization device to solve the problems existing in the prior art, realize the individual replacement of UVC lamp cores, reduce replacement costs, and reduce material waste.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] like Figures 1-11 As shown, this embodiment provides a UVC water sterilization device, including a main body and a lamp wick 200. The lamp wick 200 is detachably connected to the inside of the main body. The main body includes a host 100 and a fixing cover 300. An installation cavity is formed inside the host 100 to facilitate the installation of the lamp wick 200. One end of the host 100 is open and sealed by the fixing cover 300. The fixing cover 300 is detachably connected to the host 100, which facilitates the installation and removal of the lamp wick 200. The lamp wick 200 can be placed into the installation cavity through the opening of the host 100. By designing the lamp wick 200 to be detachable from the main body, the UVC lamp can be replaced after its lifespan expires, reducing material waste and lowering costs.

[0040] Specifically, the lamp wick 200 includes, from the outside in, a spring clamp 27, a heat-conducting sheet 26, a UVC lamp plate 28, a lamp plate tray 29, and a quartz tube 16. A Teflon sleeve 17 is fitted around the quartz tube 16 to protect it from damage. The Teflon sleeve 17 has corresponding through holes to allow the UVC lamp to irradiate the water flow for sterilization. Both the Teflon sleeve 17 and the quartz tube 16 are mounted on the lamp bracket 18. The lamp plate tray 29 is located around the Teflon sleeve. The heat-conducting sheet 26 and the UVC lamp plate 28 are arranged sequentially from the outside in. The connection between the heat-conducting sheet 26 and the lamp holder 29 is detachable. The outer side of the heat-conducting sheet 26 is used to contact the inner wall of the host 100, so that the host 100 can dissipate heat from the UVC lamp plate 28, thereby improving the heat dissipation effect. The spring clamp 27 is connected to the lamp bracket 18, and a spring 19 is provided between the spring clamp 27 and the lamp holder 29. The bottom of the lamp holder 29 is in close contact with the lamp bracket 18 under the action of the spring 19. The lamp core 200 also includes a clamping element, which can make the heat-conducting sheet 26 in close contact with the inner wall of the host 100, increasing the contact area and the tightness of the contact, thereby improving the heat dissipation effect.

[0041] The lamp wick 200 also includes a water inlet 15 and a water outlet 23. A first energizing element is connected to the water inlet 15. The first energizing element is used to contact and energize a second energizing element on the main unit 100. The first energizing element and the UVC lamp board 28 are both welded and fixed to the power cord. The water inlet 15 and the water outlet 23 are respectively located at both ends of the quartz tube 16, and the water outlet 23 is located close to the fixing cover 300. A water inlet sealing ring 14 is provided between the outer wall of the water inlet 15 and the inner wall of the bottom shell 1 of the main unit 100, and a water outlet sealing ring is provided between the water outlet 23 and the fixing cover 300. The water inlet sealing ring 14 and the water outlet sealing ring are used to improve the sealing effect and prevent water from overflowing.

[0042] A connecting groove is provided at the bottom shell 1 of the main unit 100. The water inlet component 15 is inserted into the connecting groove, which is frustum-shaped. The inner diameter of the connecting groove gradually increases from the water inlet component 15 towards the water outlet component 23. By increasing the inner diameter at the inlet, it is easier to guide the water inlet component 15 during installation and also easier to remove the water inlet component 15, while reducing the insertion and removal force. As a preferred embodiment, the angle between the generatrix of the frustum-shaped connecting groove and the axis is 2° to 8°.

[0043] The outer wall of the fixed cover 300 is provided with a groove. The main unit 100 is provided with a rotating bracket 12 at one end near the fixed cover 300. The inner wall of the rotating bracket 12 is provided with a protrusion. By screwing the protrusion into the groove, the rotating bracket 12 can be screwed tightly to the outer periphery of the fixed cover 300, which improves the connection stability and facilitates disassembly. The middle of the fixed cover 300 is provided with a first mounting hole. The water outlet 23 is located in the first mounting hole, and the end of the water outlet 23 away from the water inlet 15 extends to be flush with the end face of the fixed cover 300. A first claw 25 is installed in the water outlet 23, and the first claw 25 is set away from the water inlet 15. A first sealing ring 24 is provided between the end of the first claw 25 near the water inlet 15 and the stepped surface of the inner wall of the water outlet 23. The rotating bracket 12 is connected to one end of the main unit 100 by screws.

[0044] As a preferred embodiment, the lamp wick 200 and the fixing cover 300 can also be fixed together as one unit.

[0045] The clamping element includes two power rods 21 symmetrically arranged along the axis of the quartz tube 16. Each power rod 21 is L-shaped, with its longer section extending along the length of the quartz tube 16. The water outlet 23 has a guide groove at the corresponding position of the power rod 21, with the opening of the guide groove facing the inner wall of the main unit 100. The shorter section of the power rod 21 is slidably connected within the guide groove, allowing it to slide and thus swing. The outer side of the shorter section is a slope, which gradually extends away from the inner wall of the main unit 100 from the water outlet 23 towards the water inlet 15. One end of the longer section is connected to the lamp plate tray 29 via a first rotating shaft 20, allowing the lamp plate tray 29 to move as the longer section swings. A second rotating shaft 22 is located in the middle of the longer section, serving as a fulcrum to ensure smooth swinging of the power rod 21. Due to the spring 19... The component can press the lamp plate tray 29 with the spring 19, thereby pushing one end of the long section outward, causing the other end of the long section to drive the short section outward. Thus, the two short sections are in an outward expansion state under the action of the spring 19. In the outward expansion state, the two short sections are close to the inner wall of the host 100, which facilitates the insertion of the lamp wick 200 into the host 100. When the lamp wick 200 is inserted into the host 100 and the inclined surface contacts the inner wall of the host 100, since the side of the short section in contact with the inner wall of the host 100 is inclined, the short section can gradually rotate around the second rotation axis 22 away from the inner wall of the host 100 with the cooperation of the inclined surface and the inner wall of the host 100. This causes the long section to move outward at the end away from the short section. Then, through the structure such as the lamp plate tray 29, the heat conduction plate 26 is pushed towards the inner wall of the host 100, so that the heat conduction plate 26 is in close contact with the inner wall of the host 100, improving the heat dissipation effect.

[0046] The spring clamp 27 is connected to the lamp bracket 18. The outer wall of the UVC lamp plate 28 is provided with several spring holes. Each spring 19 is installed in the corresponding spring hole, and one end of the spring 19 abuts against the inner bottom surface of the spring hole. The other end of the spring 19 is pressed by the spring clamp 27 to achieve the effect of pressing the lamp plate tray 29 inward through the spring clamp 27.

[0047] The heat-conducting sheet 26, the UVC lamp plate 28, and the lamp plate tray 29 are connected by screws, which facilitates installation and disassembly. The heat-conducting sheet 26 is a thermally conductive silicon sheet with good thermal conductivity.

[0048] In this embodiment, the assembly of the lamp wick 200 is as follows:

[0049] (1) First, install the UVC lamp plate 28 and the heat-conducting sheet 26 on the lamp plate tray 29 in sequence and tighten them with screws. Then, connect the lamp plate tray 29 and the power rod 21 with the first rotating shaft 20.

[0050] (2) Then, the Teflon tube sleeve 17 with the hole made is put on the quartz tube 16 and then installed into the lamp bracket 18.

[0051] (3) Press the first sealing ring 24 and the first claw 25 into the water outlet part 23 of the lamp wick 200;

[0052] (4) Press the electrode copper column 13 into the water inlet 15 of the lamp wick 200;

[0053] (6) Fit the corresponding sealing rings onto the water inlet 15 and the water outlet 23 of the lamp wick 200 respectively, and then install them into the two ends of the assembly formed in step (2).

[0054] (7) Solder the power cords to the electrode copper pillar 13 and the UVC lamp plate 28 respectively;

[0055] (8) Connect the structure assembled in step (1) with the structure assembled in step (5) using the second rotating shaft 22;

[0056] (9) Finally, insert the spring 19 into the spring hole of the lamp plate tray 29, and then use the spring clamp 27 to clamp it on the lamp bracket 18 to press the spring 19.

[0057] Through the assembly of the lamp core 200 as described above, the lamp plate tray 29 is pressed tightly against the lamp bracket 18 at the bottom under the action of the spring 19, and the two ends of the power rod 21 are slightly flared outward.

[0058] The main unit 100 includes an upper shell 10, a bottom shell 1, a heat dissipation shell 11, a second energizing element, a flow meter 3, and a circuit board 5. The heat dissipation shell 11 has openings at both ends, and the bottom shell 1 is bolted to one end of the heat dissipation shell 11. A fixing cover 300 is connected to the other end of the heat dissipation shell 11. The second energizing element and the flow meter 3 are both installed inside the bottom shell 1, and the second energizing element is used to contact the first energizing element of the lamp wick 200. The upper shell 10 covers the bottom shell 1, and a second sealing ring 4 is provided between the upper shell 10 and the bottom shell 1. A reset button is also installed on the end face of the upper shell 10 away from the heat dissipation shell 11. The outer end of the upper shell 10... The surface is also equipped with a status light 9, which is electrically connected to the circuit board 5. When the status light 9 is red, it means that the UVC lamp of the lamp core 200 needs to be replaced. After replacing the UVC lamp of the lamp core 200, pressing the reset button can change the color of the status light 9, such as green, to indicate that the UVC lamp is currently in normal condition. The circuit board 5 is connected to the upper shell 10 by screws and is connected to the second power supply element through a power cord. The upper shell 10 is also provided with a second mounting hole in the middle. A second claw 8 is installed in the second mounting hole. A third sealing ring 7 is provided between the second claw 8 and the upper shell 10 at the end near the fixing cover 300.

[0059] The first energizing element is an electrode copper pillar 13 or a spring piece, and the second energizing element is a spring pin 2 or a spring piece. Then, the electrode copper pillar 13 is energized by contact with the spring pin 2, or the spring piece is energized by contact with the spring piece, or the electrode copper pillar 13 is energized by contact with the spring piece.

[0060] In this embodiment, the assembly of the host 100 is as follows:

[0061] (1) Press the spring pin 2 (POGOPIN) and the flow meter 3 into the corresponding holes of the bottom shell 1 of the main unit 100 respectively, and put the second sealing ring 4 on the bottom shell 1 of the main unit 100.

[0062] (2) Solder the status light 9 to the corresponding position on the circuit board 5;

[0063] (3) First, install the reset button 6 into the corresponding hole in the upper shell 10 of the host 100; then align the circuit board 5 and install it on the upper shell 10 of the host 100, and tighten it with screws; then press the third sealing ring 7 and the second claw 8 into the structure assembled in step (3).

[0064] (4) Align the components assembled in step (1) with the heat sink housing 11, connect them, and tighten them with screws;

[0065] (5) Solder the spring pin 2 and the circuit board 5 together with the power cord;

[0066] (6) Align the components assembled in step (3) with the components assembled in step (4), connect them, and tighten them with screws;

[0067] (7) Insert the rotating bracket 12 into the assembly assembled in step (6) and tighten it with screws.

[0068] The working principle of this embodiment is as follows:

[0069] Since the lamp wick 200 is not installed in the main unit 100, the bottom of the lamp plate tray 29 is pressed tightly against the lamp bracket 18 under the action of the spring 19, and the short section of the power rod 21 is slightly flared outward. In this way, when the lamp wick 200 is installed in the main unit 100, the heat-conducting plate 26 does not contact the heat dissipation shell 11 in the first half of the distance, so as to avoid damage to the heat-conducting plate 26. When the lamp wick 200 advances to a certain distance, the inclined surface of the short section of the power rod 21 contacts the inner wall of the heat dissipation shell 11 and causes the short section of the power rod 21 to move inward. At the same time, according to the lever principle, one end of the long section of the power rod 21 will push the heat-conducting plate 26 outward and make the heat-conducting plate 26 and the heat dissipation shell 11 stick tightly together. Then, the fixing cover 300 is screwed on to fix the lamp wick 200, thereby minimizing the problem of insufficient heat dissipation caused by damage to the heat-conducting plate 26.

[0070] Then insert water pipes at both ends and turn on the power; after water is supplied, the impeller of flow meter 3 rotates, which drives the Hall switch to work, lights up the UVC lamp, and enters the sterilization state; when the water is stopped, the impeller of flow meter 3 stops rotating, which drives the Hall switch to close, the UVC lamp lights up slightly, and enters the antibacterial work.

[0071] When status light 9 turns red, it indicates that the UVC lamp has reached the end of its lifespan and the bulb 200 needs to be replaced. Disconnect the water pipe at the outlet, then unscrew the retaining cap 300, remove the old bulb 200, insert the new bulb, screw the retaining cap 300 back on, and then press the reset button 6 to change the color of status light 9 to indicate full status. After connecting the power and water, it can work again.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
