[0002] In recent years, ultraviolet (UV) water purification technology has been widely used in drinking water, wastewater treatment, industrial water, swimming pool water treatment and other fields. UV water purification equipment using this technology is a device that uses ultraviolet (UV) technology to disinfect water.

[0014] In some embodiments of this application, the inner wall of the sterilization chamber is covered with a second reflective film for reflecting ultraviolet rays.

[0015] In some embodiments of this application, the adapter assembly includes a first adapter and a second adapter, wherein the first adapter is disposed on the outer periphery of a first end of the transparent tube, and the second adapter is disposed on the outer periphery of a second end of the transparent tube;

[0017] In some embodiments of this application, the first adapter and the second adapter are pipes, and an annular groove is provided on the outer side of the pipe.

[0018] The end faces of the first housing and the second housing are provided with semi-circular notches;

[0039] 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. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention. In the present invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0040] This document describes a UVC sterilization device. In the following description, various specific details are set forth, such as the transparent tube 1, the adapter assembly 2, and the mounting housing assembly 3, to aid in a comprehensive understanding of the embodiments of the invention. It will be apparent to those skilled in the art that embodiments of the invention can be practiced without using these specific details. In other instances, common features such as certain known installation methods of the adapter assembly 2 and the pipes are not described in detail to avoid unnecessarily obscuring the embodiments of the invention. Furthermore, it should be understood that the various embodiments shown in the accompanying drawings are merely illustrative and not necessarily drawn to scale. Although the materials and material properties of other features are not explicitly disclosed herein, they should still be considered within the scope of this invention.

[0041] The core components of existing ultraviolet (UV) water purification devices include UV lamps, reflectors, transparent panels, circuit boards, and electrolysis columns. UV lamps typically use UVC LEDs or mercury lamps, with UVC LEDs gradually replacing traditional mercury lamps due to their advantages such as no mercury pollution, small size, and long lifespan. The transparent panels in the devices are usually made of quartz glass to ensure effective UV transmission.

[0042] Existing ultraviolet water purification devices are used in various settings, including laboratories, home water purifiers, and hospitals, providing them with sufficient ability to kill bacteria and microorganisms.

[0043] However, the lifespan of existing UVC LEDs is generally less than 10,000 hours. Therefore, if the UVC LEDs inside the UV water purification equipment run out of lifespan, the UV water purification equipment needs to be replaced. However, existing UV water purification equipment is bulky, expensive to replace, and inconvenient for long-term maintenance and use.

[0044] See Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of an overall structure of the UVC sterilization device provided in an embodiment of this application. Figure 2 This is a schematic diagram of the internal structure of a UVC sterilization device provided in an embodiment of this application. In a first aspect, embodiments of the present invention provide a UVC sterilization device, which may include:

[0045] Transparent tube 1;

[0046] Adapter assembly 2, which is disposed at both ends of the transparent tube 1;

[0047] The mounting housing assembly 3 has a sterilization chamber 31 inside, and the transparent tube 1 is located inside the sterilization chamber 31. Both ends of the mounting housing assembly 3 are fixed to the adapter assembly 2 respectively. The mounting housing 3 is equipped with an LED light strip assembly 4, which is used to generate ultraviolet light and irradiate the transparent tube 1.

[0048] It is understood that the transparent tube 1 includes, but is not limited to, straight tubes, spiral tubes, serpentine tubes or other irregularly shaped tubes. The material of the transparent tube 1 can be a UV-resistant material, including but not limited to quartz glass. It should be understood that the detachable connection between the adapter assembly 2 and the transparent tube 1 can be used to manually replace the transparent tube 1, so as to clean the scale and other dirt on the inner wall of the transparent tube 1 in a timely manner, and avoid affecting the UV sterilization effect of this sterilization device.

[0049] It is understandable that the adapter assembly 2 is used to connect pipes that transmit bacteria-laden media, including but not limited to city water pipes, beverage equipment water pipes, laboratory water pipes, and hospital water pipes.

[0050] It is understood that the mounting housing assembly 3 includes, but is not limited to, cylinders and cuboids, and the sterilization chamber 31 includes, but is not limited to, cylindrical cavities and cuboid cavities. The material of the mounting housing assembly 3 should be an ultraviolet-shielding material to avoid human contact with ultraviolet radiation. The connection method between the mounting housing assembly 3 and the adapter includes, but is not limited to, flange connection and interference fit connection.

[0051] It should be understood that the LED light strip assembly 4 is a product with a relatively short service life, usually 8,000 to 10,000 hours. Since the UVC sterilization device isolates the bacteria-carrying medium from the LED light strip assembly 4 through the transparent tube 1, it avoids the potential risk of damage (exposing the LED light strip assembly 4 to a humid environment for a long time) and effectively improves the service life of the LED light strip assembly 4.

[0052] It is understandable that the LED light strip assembly 4 is evenly arranged around the inner wall of the sterilization chamber 31. The specific arrangement can be a straight line arrangement or a spiral arrangement. The LED light strip assembly 4 can be multiple LED light strips with different radiation intensities, so that it can adjust its sterilization ability according to the feedback of the final water quality test data and achieve its stable ultraviolet sterilization function.

[0053] The beneficial effects of this application are as follows: Firstly, the UVC sterilization device provided by this application radiates ultraviolet light onto the bacterial medium inside the transparent tube 1 by installing an LED light strip assembly 4 inside the installation housing assembly 2 (which prevents ultraviolet light leakage) and outside the transparent tube 1. This achieves sufficient sterilization effect while directly connecting the bacterial medium conveying pipeline, realizing flow-through sterilization of the bacterial medium, and miniaturizing the UVC sterilization device, thus reducing production costs. Secondly, since the transparent tube 1 and the adapter assembly 2, the adapter assembly 2 and the installation housing assembly 3, and the LED light strip assembly 4 and the installation housing assembly 3 are detachable in the UVC sterilization device provided by this application, the LED light strip assembly 4 in the UVC sterilization device can be easily replaced when its service life is short, reducing maintenance costs.

[0054] In some embodiments of this application, see Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of the internal structure of the UVC sterilization device provided in an embodiment of this application. Figure 3 This is another internal structure diagram of the UVC sterilization device provided in the embodiment of this application. The transparent tube 1 is a spiral tube, and the transparent tube 1 has a long strip-shaped receiving space formed along the axial direction. The LED light strip assembly 4 includes a plurality of first LED light strips 41 and a plurality of second LED light strips 42. The plurality of first LED light strips 41 are evenly distributed on the inner wall of the sterilization chamber 31.

[0055] A cylindrical support 11 is provided within the accommodating space, and multiple second LED light strips 42 are evenly distributed on the outer periphery of the support 11; and / or,

[0056] A cylindrical support 11 is provided in the accommodating space, and a first reflective film 12 for reflecting ultraviolet rays is evenly distributed on the outer periphery of the support 11.

[0057] It is understandable that the outer periphery of the bracket 11 can be simultaneously provided with a first reflective film 12 and a second LED light strip 42 to enhance the sterilization effect of the transparent tube 1.

[0058] Understandably, the second LED light strip 42 can be evenly distributed 360 degrees around the outer perimeter of the bracket 11.

[0059] This application, by evenly distributing the LED light strip assembly 4 on the inner wall of the sterilization chamber 31 and the middle of the spiral tube, enables the inner and outer sides of the spiral tube to be simultaneously irradiated by ultraviolet light. This increases the residence time of the bacteria-carrying medium within a limited space, improves the uniformity of ultraviolet irradiation in the sterilization chamber 31, and enhances sterilization efficiency.

[0060] In some embodiments of this application, a heat dissipation groove 32 is provided on the outer peripheral surface of the mounting housing assembly 3, and the LED light strip assembly 4 is thermally coupled to the inner wall of the mounting housing assembly 3.

[0061] It is understandable that the shape of the heat dissipation groove 32 can be a straight groove or a curved groove.

[0062] Understandably, since the installation housing assembly 3 needs to prevent ultraviolet leakage, it is not possible to create gaps on the surface of the installation housing assembly 3 for heat dissipation.

[0063] In this embodiment, by providing a plurality of heat dissipation grooves 32 on the outer peripheral surface of the mounting housing assembly 3, the surface area of ​​the mounting housing assembly 3 can be increased, thereby achieving a faster heat dissipation effect.

[0064] In some embodiments of this application, see Figure 4 As shown, Figure 4This is a schematic diagram of the third internal structure of the UVC sterilization device provided in the embodiments of this application. A water flow sensor 5 is provided at one end of the housing assembly 3. The output end of the water flow sensor 5 is electrically connected to the input end of the LED light strip assembly 4. The water flow sensor 5 is used to control the LED light strip assembly 4 to turn on when it detects that there is a bacterial medium passing through the transparent tube 1, and to control the LED light strip assembly 4 to turn off when it detects that there is no bacterial medium passing through the transparent tube 1.

[0065] Understandably, the water flow sensing device 5 can be composed of three main parts: a sensor, a controller, and an actuator. The sensor is responsible for detecting the fluid flow in the bacterial medium pipeline, the controller receives the signal from the sensor and determines whether the switching conditions are met, and finally controls the switch of the LED light strip assembly 4 by controlling the actuator.

[0066] Since the lifespan of the LED light strip assembly 4 is typically less than 10,000 hours, this embodiment of the application sets a water flow sensor 5 at one end of the mounting housing assembly 3 and connects this end to the inflow end of the bacterial medium via an adapter assembly 2. This allows the LED light strip assembly 4 to be turned on when the water flow sensor 5 detects that bacterial medium is passing through the transparent tube 1, and to be turned off when the water flow sensor 5 detects that no bacterial medium is passing through the transparent tube 1. This saves the usage time of the LED light strip assembly 4, achieving not only energy saving and environmental protection, but also increasing the lifespan of the LED light strip assembly 4 by more than ten times, thereby increasing the lifespan of the entire UVC sterilization device.

[0067] In some embodiments of this application, the inner wall of the sterilization chamber 31 is covered with a second reflective film 33 for reflecting ultraviolet rays.

[0068] In this embodiment, by laying a second reflective film 33 on the inner wall of the sterilization chamber 31, the inner wall of the sterilization chamber 31 can be prevented from absorbing part of the ultraviolet rays, and the ultraviolet rays irradiated on the inner wall of the sterilization chamber 31 can be reflected to the transparent tube 1, thereby improving the sterilization efficiency of the UVC sterilization device.

[0069] In some embodiments of this application, see Figure 3 and Figure 5 As shown, Figure 3 This is a schematic diagram of another internal structure of the UVC sterilization device provided in the embodiments of this application. Figure 5 This is a schematic diagram of a mounting housing assembly provided in an embodiment of this application. The adapter assembly 2 includes a first adapter 21 and a second adapter 22. The first adapter 21 is disposed on the outer periphery of the first end of the transparent tube 1, and the second adapter 22 is disposed on the outer periphery of the second end of the transparent tube 1.

[0070] The mounting housing assembly 3 includes a first housing 34 and a second housing 35. The first housing 34 and the second housing 35 are detachably connected. The first housing 34 has a first mounting surface, and the second housing 35 has a second mounting surface that matches the first mounting surface. The axis of the transparent tube 1 is located on the first mounting surface.

[0071] It is understood that the connection between the adapter assembly 2 and the transparent tube 1 can be in the form of snap-fit ​​and interference fit, and a seal can be provided between the adapter assembly 2 and the transparent tube 1.

[0072] During the installation of the UVC sterilization device in this application, the transparent tube 1 is first connected to the sterilization medium delivery pipeline through the first adapter 21 and the second adapter 22 respectively. Then, the first housing 34 and the second housing 35 are fastened together around the transparent tube 1, and the internal space forms a sterilization chamber 31 for accommodating the transparent tube 1. Then, the first housing 34 and the second housing 35 are fixed. Finally, the mounting housing assembly 3 is fixed to the first adapter 21 and the second adapter 22 respectively, thereby completing the installation of the entire UVC sterilization device and the sterilization medium delivery pipeline.

[0073] During the disassembly process of the UVC sterilization device in this application, the housing assembly 3 is first disassembled from the first adapter 21 and the second adapter 22 respectively, and then the first housing 34 is disassembled from the second housing 35. Subsequently, the LED light strip assembly 4 in the sterilization chamber 31 can be taken out and replaced. If it is necessary to further clean the transparent tube 1, the transparent tube 1 can be disassembled from the first adapter 21 and the second adapter 22 to achieve cleaning of the transparent tube 1.

[0074] In this embodiment, if the transparent tube 1 and the conveying pipe for the bacterial medium are successfully installed, and the LED light strip assembly 4 reaches its service life during use, it is only necessary to disassemble the first housing 34, the second housing 35, and the adapter assembly 2, and then replace the LED light strip assembly 4 inside the first housing 34 and the second housing 35. This allows the LED light strip assembly 4 to be replaced without disassembling the transparent tube 1 and the conveying pipe for the bacterial medium, further simplifying the steps of replacing the LED light strip assembly 4 and enabling users to conveniently and quickly maintain the sterilization device in this application themselves.

[0075] In some embodiments of this application, see Figure 3 and Figure 5 As shown, Figure 3 This is a schematic diagram of another internal structure of the UVC sterilization device provided in the embodiments of this application. Figure 5 This is a schematic diagram of a mounting housing assembly provided in an embodiment of this application. The first adapter 21 and the second adapter 22 are tubes, and an annular groove 23 is provided on the outer side of the tube.

[0076] The end faces of the first housing 34 and the second housing 35 are provided with semi-circular notches 36;

[0077] The bottom of the annular groove 23 abuts against the notch 36.

[0078] Specifically, the first adapter 21 and the second adapter 22 can be connected to pipelines that transport bacteria-carrying media, including but not limited to screw connections, flange connections, and interference fits.

[0079] In the installation process of the UVC sterilization device in this application embodiment, the matching of the annular groove 23 and the notch 36 allows for the fixing of the mounting housing assembly 3 to the first adapter 21 and the second adapter 22 by only the fixed connection between the first housing 34 and the second housing 35, simplifying the installation steps. In addition, during the fixing of the first adapter 21 and the second adapter 22 to the mounting housing assembly 3, the ultraviolet light emitted in the sterilization chamber 31 is blocked by the first adapter 21 and the second adapter 22, thereby avoiding the situation where ultraviolet light leakage from the UVC sterilization device may cause damage to the human body.

[0080] Furthermore, a filtration device, such as an activated carbon filtration device or an ultrafiltration membrane filtration module, can be connected to the input end of the UVC sterilization device to achieve the filtration function before ultraviolet purification of the sterilization device in this application.

[0081] Furthermore, a water quality detection module can be installed at the input end of the UVC sterilization device. Based on the feedback of the monitoring data in the water quality detection module, the user can be reminded to clean the transparent tube or increase the number of UVC sterilization devices connected in series. This further ensures that the UVC sterilization device in this application can operate stably, so as to achieve a balanced and efficient sterilization quality over time.

[0082] Furthermore, an automatic cleaning device for the transparent tube 1 can be integrated into the UVC sterilization device to achieve regular cleaning based on the monitoring data in the water quality detection module, thereby avoiding dirt on the inner wall of the transparent tube 1 and reducing the adverse effects of such conditions on the UV sterilization effect in the sterilization chamber 31.

[0083] See Figure 6 and Figure 7 As shown, Figure 6 This is another overall structural diagram of the UVC sterilization device provided in the embodiments of this application. Figure 7 This is a cross-sectional structural diagram of the UVC sterilization device provided in the embodiment of this application. Both ends of the transparent tube 1 are located on the first mounting surface of the first housing 34, and the line connecting the two ends of the transparent tube 1 is parallel to the axis of the transparent tube 1. The first housing 34 and the second housing 35 are provided with support plates 37 inside, and the support plates 37 are used to fix the two ends of the bracket 11 inside the transparent tube 1.

[0084] Specifically, the support plate 37 is provided with a card interface, and the outer walls of both ends of the bracket 11 are provided with annular card grooves. The annular card grooves and the card interface cooperate with each other to prevent the bracket 11 from moving along the axis of the transparent tube 1.

[0085] Understandably, the support plate 37 is used to fix the two ends of the bracket 11 inside the transparent tube 1, so as to prevent the second LED light strip 42 outside the bracket 11 from rubbing against the transparent tube 1 due to vibration, and to improve the service life of the second LED light strip 42.

[0086] Meanwhile, the support plate 37 can be used to support the transparent tube 1, preventing the transparent tube 1 from shifting in the sterilization chamber 31 due to water pressure or external vibration, scratching the first LED light strip 41, or causing damage to itself.

[0087] Furthermore, a reflective film can be provided on the sidewall of the support plate 37 to reflect ultraviolet rays.

[0088] It is understandable that the annular slots on the outer walls of both ends of the bracket 11 and the card interfaces on the support plate 37 cooperate with each other to separate the transparent tube 1 from the first housing 34 and the second housing 35, and at the same time separate the bracket 11 from the first housing 34 and the second housing 35, making it easier to replace the second LED light strip 42 on the outer surface of the bracket 11, and achieving the effect of more convenient and faster disassembly and assembly of the second LED light strip 42.

[0089] It is understandable that the second LED light strip 42 in this application can also be replaced without having to separate the transparent tube 1 and the adapter assembly 2 from the pipeline that carries the bacterial medium.

[0090] This application provides support plates 37 inside both ends of the first housing 34 and the second housing 35, with locking interfaces on the support plates 37 and annular locking grooves that cooperate with the locking interfaces on the outer walls of both ends of the bracket 11. First, this can prevent the second LED light strip 42 outside the bracket 11 from rubbing against the transparent tube 1 due to vibration, thus improving the service life of the second LED light strip 42. The second support plate 37 is used to support the transparent tube 1, preventing the transparent tube 1 from shifting in the sterilization chamber 31 and rubbing against the first LED light strip 41. Third, it can separate the bracket 11 from the first housing 34 and the second housing 35 while separating the transparent tube 1 from them, thus making the disassembly and assembly of the second LED light strip 42 more convenient and faster.

[0091] See Figure 8 As shown, Figure 8This is a schematic diagram of a transparent tube provided in an embodiment of this application. In addition to the spiral tube mentioned above, the transparent tube 1 can also be a serpentine tube. The serpentine transparent tube allows the bacteria-carrying medium to flow back and forth along the length of the sterilization chamber 31, thereby increasing the residence time of the bacteria-carrying medium in the sterilization chamber 31 and improving the sterilization ability of the UVC sterilization device on the bacteria-carrying medium.

[0092] Secondly, see Figure 9 and Figure 10 As shown, Figure 9 This is a schematic diagram of a UVC sterilization component provided in an embodiment of this application. Figure 10 This is another structural schematic diagram of the UVC sterilization component provided in the embodiments of this application. Embodiments of the present invention provide a UVC sterilization component, including multiple UVC sterilization devices as described above, the multiple UVC sterilization devices being arranged in combination along the flow direction of the bacteria-carrying medium.

[0093] The UVC sterilization component provided in this application is small in size and low in cost, so multiple sterilization devices can be configured for combined use to improve efficiency.

[0094] In some embodiments of this application, multiple UVC sterilization devices are arranged in series along the flow direction of the bacteria-carrying medium.

[0095] The embodiments of this application improve the ultraviolet sterilization capability of UVC sterilization devices by arranging multiple UVC sterilization devices in series along the direction of bacterial flow.

[0096] In some embodiments of this application, multiple UVC sterilization devices are arranged in parallel along the flow direction of the bacteria-carrying medium.

[0097] The embodiments of this application can increase the flow rate of the UVC sterilization devices by arranging multiple UVC sterilization devices in parallel along the flow direction of the bacteria-carrying medium.

[0098] Based on this, multiple UVC sterilization devices can be connected in parallel to form a first module, and then multiple first modules can be connected in series for use, which can multiply the sterilization capability of the UVC sterilization device and the flow rate of the UVC sterilization module.

[0099] Alternatively, multiple UVC sterilization devices can be connected in series to form a second module, and then multiple second modules can be connected in parallel. This can also increase the sterilization capability of the UVC sterilization device and the flow rate of the UVC sterilization module by multiple times.

[0100] Based on this, heat dissipation medium can be filled into the gaps between multiple UVC sterilization devices to improve the overall heat dissipation capacity of the UVC sterilization module.

[0101] Based on this, a temperature control device can be installed in the UVC sterilization module to detect whether there is a temperature abnormality in each UVC sterilization device, so that the UVC sterilization module stops working.

[0102] Based on this, a water flow sensor can be installed inside the UVC sterilization module. This water flow sensor can be installed at the input port of the bacterial medium of the entire UVC sterilization module to avoid repeated detection and reduce the production cost of the entire UVC sterilization module.

[0103] Based on this, due to Figure 10 Multiple UVC sterilization devices are arranged in parallel along the flow direction of the bacteria-carrying medium. Figure 10 The one used is Figure 6 The UVC sterilization device in it can Figure 10 The external pipe perpendicular to the axis of the UVC sterilization device is offset from the axis of the bracket 11 where the second LED light strip 42 is located, so that the parallel UVC sterilization module can be installed and removed without disconnecting the transparent tube 1, the adapter assembly 2 and the conveying pipe of the bacteria-carrying medium.

[0104] Furthermore, the first housing 34 and the second housing 35 of the parallel UVC sterilization module can be integrally molded to further simplify the installation process.

[0105] The embodiments of the present invention have been described in detail above.
