[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the drawings; while "inside" and "outside" refer to the outline of the device.

[0020] A UVC sterilization device is described herein. In the following description, various specific details, such as the transparent tube 1, the adapter assembly 2, and the mounting shell assembly 3, are described in detail to help fully understand the embodiments of the present invention. It is obvious to those skilled in the art that the embodiments of the present invention can be practiced without using these specific details. In other cases, common features, such as certain known methods of installing the adapter assembly 2 and the pipeline, are not described in detail to avoid unnecessarily obscuring the embodiments of the present invention. In addition, it should be understood that the various embodiments shown in the drawings are only schematic representations and are not necessarily drawn to scale. Although the materials and material properties of other features are not explicitly disclosed herein, they should still be considered to be within the scope of the present invention.

[0021] The core components of existing ultraviolet water purification devices include ultraviolet lamps, reflective cups, transparent plates, circuit boards, and electrolytic columns. Ultraviolet lamps usually use UVC LEDs or mercury lamps, among which UVC LEDs are gradually replacing traditional mercury lamps due to their advantages such as no mercury pollution, small size, and long life. The transparent plate in the device usually uses quartz glass to ensure the effective transmission of ultraviolet rays.

[0022] Existing ultraviolet water purification devices are used in laboratories, home water purifiers, hospitals, etc., providing them with sufficient ability to kill bacteria and microorganisms.

[0023] However, the service life of existing UVC LEDs is generally less than 10,000 hours. Therefore, if the service life of the UVC LED inside the ultraviolet water purification equipment is exhausted, the ultraviolet water purification equipment needs to be replaced. However, the existing ultraviolet water purification equipment is bulky and expensive to replace, which is not convenient for long-term maintenance and use.

[0024] See also Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the overall structure of the UVC sterilization device provided in the embodiment of the present application. Figure 2 This is a schematic diagram of the internal structure of a UVC sterilization device provided in an embodiment of the present application. In a first aspect, an embodiment of the present invention provides a UVC sterilization device, which may include: Transparent tube 1; The adapter assembly 2 is arranged at both ends of the transparent tube 1; The shell assembly 3 is installed, and a sterilization chamber 31 is formed in the shell assembly 3. The transparent tube 1 is located in the sterilization chamber 31. The two ends of the shell assembly 3 are respectively fixed to the adapter assembly 2. An LED light bar assembly 4 is arranged in the shell 3. The LED light bar assembly 4 is used to generate ultraviolet rays and irradiate the transparent tube 1.

[0025] It can be understood that the transparent tube 1 includes but is not limited to straight tubes, spiral tubes, serpentine tubes or other special-shaped tubes. The material of the transparent tube 1 can be a material that is resistant to UV aging, 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 facilitate timely cleaning of dirt such as scale on the inner wall of the transparent tube 1, and avoid affecting the ultraviolet sterilization effect of the sterilization device.

[0026] It can be understood that the adapter assembly 2 is used to connect pipes that transmit bacterial media, including but not limited to city tap water pipes, tap water pipes of beverage equipment, tap water pipes of laboratories and water pipes of hospitals.

[0027] It can be understood that the installation shell component 3 includes but is not limited to a cylinder and a cuboid, the sterilization chamber 31 includes but is not limited to a cylindrical cavity and a cuboid cavity, the material of the installation shell component 3 should be an ultraviolet shielding material to avoid human contact with ultraviolet radiation, and the connection method between the installation shell component 3 and the adapter includes but is not limited to a flange connection and an interference connection.

[0028] It should be understood that the LED light bar 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 bacterial medium from the LED light bar assembly 4 through the transparent tube 1, it avoids potential damage risks (exposing the LED light bar assembly 4 to a humid environment for a long time), effectively improving the service life of the LED light bar assembly 4.

[0029] It can be understood that the LED light bar assembly 4 is evenly arranged around the inner wall of the sterilization chamber 31. The specific arrangement can be a linear arrangement or a spiral arrangement. The LED light bar assembly 4 can be a plurality of LED light bars with different radiation intensities, which is convenient for it to adjust its own sterilization ability according to the feedback of the final water quality detection data to achieve its stable ultraviolet sterilization function.

[0030] Beneficial effects of the present application: On the one hand, the UVC sterilization device provided by the present application radiates ultraviolet rays to the bacterial medium in the transparent tube 1 through the LED light bar assembly 4 arranged in the anti-ultraviolet light leakage installation shell assembly 2 and outside the transparent tube 1, so that while achieving sufficient sterilization effect, it can directly connect the bacterial medium delivery pipeline to realize flow-through sterilization of the bacterial medium, and make the UVC sterilization device miniaturized to reduce production costs. On the other hand, since the transparent tube 1 and the adapter assembly 2, the adapter assembly 2 and the installation shell assembly 3, and the LED light bar assembly 4 and the installation shell assembly 3 in the UVC sterilization device provided by the present application are detachable and installed, the adapter assembly 2 and the installation shell assembly 3 are detachable and installed, and the LED light bar assembly 4 and the installation shell assembly 3 are detachable and installed, the LED light bar assembly 4 in the UVC sterilization device can be easily replaced when the service life is not long, thereby reducing maintenance costs.

[0031] 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 the embodiment of the present application. Figure 3 Another schematic diagram of the internal structure of the UVC sterilization device provided in the embodiment of the present application, the transparent tube 1 is a spiral tube, the transparent tube 1 forms a long strip-shaped accommodation space along the axial direction, the LED light bar assembly 4 includes a plurality of first LED light bars 41 and a plurality of second LED light bars 42, and the plurality of first LED light bars 41 are evenly distributed on the inner wall of the sterilization chamber 31; A cylindrical bracket 11 is disposed in the accommodation space, and a plurality of second LED light strips 42 are evenly distributed on the periphery of the bracket 11; and / or, A cylindrical bracket 11 is arranged in the accommodating space, and a first reflective film 12 for reflecting ultraviolet rays is evenly distributed on the outer circumference of the bracket 11 .

[0032] It is understandable that the first reflective film 12 and the second LED light strip 42 can be simultaneously disposed on the periphery of the bracket 11 to enhance the sterilization effect of the transparent tube 1 .

[0033] It is understandable that the second LED light strip 42 can be evenly distributed 360 degrees around the periphery of the bracket 11 .

[0034] The present application evenly distributes the LED light strip assembly 4 on the inner wall of the sterilization chamber 31 and the middle of the spiral tube, so that the inner and outer sides of the spiral tube are irradiated with ultraviolet rays at the same time, which can increase the residence time of the bacterial medium in a limited space, improve the uniformity of ultraviolet irradiation in the sterilization chamber 31, and enhance the sterilization efficiency.

[0035] In some embodiments of the present application, a heat dissipation groove 32 is provided on the outer peripheral surface of the mounting shell component 3 , and the LED light bar component 4 is thermally coupled to the inner wall of the mounting shell component 3 .

[0036] It is understandable that the shape of the heat dissipation groove 32 can be a straight groove or a curved groove.

[0037] It is understandable that, since the installation of the shell component 3 needs to avoid the leakage of ultraviolet rays, it is impossible to set gaps on the surface of the installation shell component 3 for heat dissipation.

[0038] In the embodiment of the present application, a plurality of heat dissipation grooves 32 are provided on the outer peripheral surface of the mounting shell component 3, so that the surface area of ​​the mounting shell component 3 can be increased, thereby achieving a faster heat dissipation effect.

[0039] In some embodiments of this application, see Figure 4 As shown, Figure 4 This is a schematic diagram of the third internal structure of the UVC sterilization device provided in an embodiment of the present application. A water flow sensing device 5 is provided at one end of the installation shell assembly 3. The output end of the water flow sensing device 5 is electrically connected to the input end of the LED light bar assembly 4. The water flow sensing device 5 is used to control the LED light bar assembly 4 to turn on when it detects that a bacterial medium passes through the transparent tube 1, and to control the LED light bar assembly 4 to turn off when it detects that no bacterial medium passes through the transparent tube 1.

[0040] It can be understood that the water flow sensing device 5 can be composed of three major parts: a sensor, a controller and an actuator, wherein 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.

[0041] Since the service life of the LED light bar assembly 4 is usually less than 10,000 hours, the embodiment of the present application arranges a water flow sensing device 5 at one end of the mounting shell assembly 3, and connects the end with the inflow end of the bacterial medium through the adapter assembly 2, so that when the water flow sensing device 5 detects that there is a bacterial medium passing through the transparent tube 1, the LED light bar assembly 4 is controlled to be turned on, and when the water flow sensing device 5 detects that there is no bacterial medium passing through the transparent tube 1, the LED light bar assembly 4 is controlled to be turned off, thereby saving the use time of the LED light bar assembly 4, not only achieving the effect of energy saving and environmental protection, but also improving the service life of the LED light bar assembly 4, increasing its service life by more than ten times, thereby improving the service life of the entire UVC sterilization device.

[0042] In some embodiments of the present application, the inner wall of the sterilization chamber 31 is paved with a second reflective film 33 for reflecting ultraviolet rays.

[0043] In the embodiment of the present application, 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 to the inner wall of the sterilization chamber 31 are reflected to the transparent tube 1, thereby improving the sterilization efficiency of the UVC sterilization device.

[0044] In some embodiments of this application, see Figure 3 and Figure 5 As shown, Figure 3 This is another schematic diagram of the internal structure of the UVC sterilization device provided in the embodiment of the present application. Figure 5 A schematic diagram of the structure of the mounting housing assembly provided in an embodiment of the present application, the adapter assembly 2 includes a first adapter 21 and a second adapter 22, the first adapter 21 is arranged at the periphery of the first end of the transparent tube 1, and the second adapter 22 is arranged at the periphery of the second end of the transparent tube 1; The mounting shell assembly 3 includes a first shell 34 and a second shell 35. The first shell 34 and the second shell 35 are detachably connected. The first shell 34 has a first mounting surface, and the second shell 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.

[0045] It is understandable that the connection modes between the adapter assembly 2 and the transparent tube 1 include but are not limited to snap connection and interference connection, and a seal may be provided between the adapter assembly 2 and the transparent tube 1 .

[0046] During the installation process of the UVC sterilization device in the present 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, and then the first shell 34 and the second shell 35 are buckled together around the transparent tube 1, and the internal space thereof forms a sterilization chamber 31 for accommodating the transparent tube 1, and then the first shell 34 and the second shell 35 are fixed, and finally the installation shell 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.

[0047] During the disassembly process of the UVC sterilization device in the present application, the installation shell assembly 3 is first disassembled from the first adapter 21 and the second adapter 22 respectively, and then the first shell 34 and the second shell 35 are disassembled, and then the LED light strip assembly 4 in the sterilization chamber 31 can be taken out for replacement. If the transparent tube 1 needs to be further cleaned, the transparent tube 1 and the first adapter 21 and the second adapter 22 can be disassembled to clean the transparent tube 1.

[0048] In the embodiment of the present application, after the transparent tube 1 and the conveying pipeline of the bacterial medium are successfully installed, if the LED light bar assembly 4 reaches the end of its service life during use, it is only necessary to disassemble the first shell 34, the second shell 35 and the adapter assembly 2 from each other, and then replace the LED light bar assembly 4 on the inner side of the first shell 34 and the second shell 35, so that the LED light bar assembly 4 can be replaced without disassembling the transparent tube 1 and the conveying pipeline of the bacterial medium, further simplifying the steps of replacing the LED light bar assembly 4, so that the user can conveniently and quickly maintain the sterilization device in the present application by themselves.

[0049] In some embodiments of this application, see Figure 3 and Figure 5 As shown, Figure 3 This is another schematic diagram of the internal structure of the UVC sterilization device provided in the embodiment of the present application. Figure 5 A schematic diagram of the structure of the mounting housing assembly provided in the embodiment of the present application, the first adapter 21 and the second adapter 22 are tube bodies, and an annular groove 23 is provided on the outer side surface of the tube body; Semicircular notches 36 are provided at both end surfaces of the first shell 34 and the second shell 35; The bottom of the annular groove 23 abuts against the notch 36 .

[0050] Specifically, the first adapter 21 and the second adapter 22 can be connected to the pipeline for conveying the bacteria-carrying medium by means of, but not limited to, a screw connection, a flange connection, and an interference connection.

[0051] In the installation process of the UVC sterilization device in the embodiment of the present application, only a fixed connection between the first shell 34 and the second shell 35 is required through the matching of the annular groove 23 and the notch 36, so that the installation shell assembly 3 and the first adapter 21 and the second adapter 22 can be fixed, thereby simplifying the installation steps. In addition, in this fixing method, during the process of fixing the first adapter 21 and the second adapter 22 to the installation shell assembly 3 respectively, the ultraviolet light emitted in the sterilization chamber 31 is blocked by the first adapter 21 and the second adapter 22, thereby avoiding the leakage of ultraviolet light in the UVC sterilization device that causes damage to the human body.

[0052] Furthermore, a filtering device, such as an activated carbon filtering device or an ultrafiltration membrane filtering module, may be connected to the input end of the UVC sterilization device to achieve the filtering function before ultraviolet purification of the sterilization device in the present application.

[0053] Furthermore, a water quality detection module can be set at the input end of the UVC sterilization device, and the user can be reminded to clean the transparent tube or increase the number of UVC sterilization devices in series based on the feedback of the monitoring data in the water quality detection module, so as to further realize the stable operation of the UVC sterilization device in this application, so as to achieve efficient sterilization quality balance in the time dimension.

[0054] Furthermore, an automatic cleaning device for the transparent tube 1 can be integrated on the UVC sterilization device to achieve regular cleaning according to 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 effect of this situation on the ultraviolet sterilization effect in the sterilization chamber 31.

[0055] See also Figure 6 and Figure 7 As shown, Figure 6 This is another schematic diagram of the overall structure of the UVC sterilization device provided in the embodiment of the present application. Figure 7 This is a schematic cross-sectional structure diagram of the UVC sterilization device provided in an embodiment of the present application. Both ends of the transparent tube 1 are located on the first mounting surface of the first shell 34, and the connecting line of the two ends of the transparent tube 1 is parallel to the axis of the transparent tube 1, and support plates 37 are provided inside both ends of the first shell 34 and the second shell 35, and the support plates 37 are used to fix the two ends of the bracket 11 in the transparent tube 1.

[0056] Specifically, a card interface is provided on the support plate 37 , and annular card grooves are provided on the outer walls at both ends of the bracket 11 . The annular card grooves and the card interface cooperate with each other to prevent the bracket 11 from moving along the axial direction of the transparent tube 1 .

[0057] It is understandable that the support plate 37 is used to fix the two ends of the bracket 11 in the transparent tube 1 to prevent the second LED light bar 42 outside the bracket 11 from scratching the transparent tube 1 due to vibration, thereby increasing the service life of the second LED light bar 42.

[0058] At the same time, the support plate 37 can be used to support the transparent tube 1 to prevent the transparent tube 1 from shifting in the sterilization chamber 31 due to the impact of water pressure or external vibration, thereby scratching the first LED light strip 41 or preventing itself from being damaged.

[0059] Furthermore, a reflective film may be provided on the side wall of the support plate 37 to reflect ultraviolet rays.

[0060] It can be understood that the annular card grooves on the outer walls at both ends of the bracket 11 cooperate with the card interface on the support plate 37 to separate the bracket 11 from the first shell 34 and the second shell 35 while separating the transparent tube 1 from the first shell 34 and the second shell 35, and at the same time separate the bracket 11 from the transparent tube 1, making it easier to replace the second LED light strip 42 on the outer surface of the bracket 11, and achieving a more convenient and rapid disassembly and assembly of the second LED light strip 42.

[0061] It is understandable that the second LED light bar 42 in the present application can also be replaced without disassembling the transparent tube 1 and the adapter assembly 2 from the pipeline for conveying the bacteria-carrying medium.

[0062] In the present application, a support plate 37 is arranged inside both ends of the first shell 34 and the second shell 35, a card interface is arranged on the support plate 37, and an annular card groove cooperating with the card interface is arranged on the outer walls of both ends of the bracket 11. First, it can prevent the second LED light bar 42 outside the bracket 11 from being scratched by the transparent tube 1 due to vibration, thereby improving the service life of the second LED light bar 42. The second support plate 37 is used to support the transparent tube 1 to prevent the transparent tube 1 from shifting in the sterilization chamber 31 and scratching the first LED light bar 41. Third, when the transparent tube 1 is separated from the first shell 34 and the second shell 35, the bracket 11 can be separated from the first shell 34 and the second shell 35, thereby achieving a more convenient and rapid disassembly and assembly of the second LED light bar 42.

[0063] See also Figure 8 As shown, Figure 8 This is a structural schematic diagram of a transparent tube provided in an embodiment of the present application. In addition to the spiral tube mentioned above, the transparent tube 1 can also be a serpentine tube, wherein the serpentine transparent tube can make the bacteria-carrying medium reciprocate along the length direction of the sterilization chamber 31, thereby increasing the residence time of the bacteria-carrying medium in the sterilization chamber 31, so as to improve the sterilization ability of the UVC sterilization device on the bacteria-carrying medium.

[0064] Second, see Fig. 9 and Fig.10 As shown, Fig. 9 A schematic diagram of the structure of the UVC sterilization component provided in the embodiment of the present application, Fig.10 Another structural schematic diagram of the UVC sterilization assembly provided in the embodiment of the present application. The embodiment of the present invention provides a UVC sterilization assembly, comprising a plurality of UVC sterilization devices of any of the above items, wherein the plurality of UVC sterilization devices are arranged in combination along the flow direction of the bacteria-carrying medium.

[0065] The UVC sterilization assembly provided in the embodiment of the present application is small in size and low in cost, so it can be configured to be used in combination with multiple sterilization devices to improve the use efficiency.

[0066] In some embodiments of the present application, a plurality of UVC sterilization devices are combined and arranged in series along the flow direction of the bacteria-carrying medium.

[0067] The embodiment of the present application can improve the ultraviolet sterilization capability of the UVC sterilization device by combining and arranging a plurality of UVC sterilization devices in series along the direction of the bacteria-carrying flow.

[0068] In some embodiments of the present application, a plurality of UVC sterilization devices are arranged in parallel along the flow direction of the bacteria-carrying medium.

[0069] The embodiment of the present application arranges a plurality of UVC sterilization devices in parallel along the flow direction of the bacteria-carrying medium, thereby increasing the flow rate of the UVC sterilization devices.

[0070] On this basis, multiple UVC sterilization devices can be connected in parallel to form a first module, and then multiple first modules can be used in series, which can increase the sterilization ability of the UVC sterilization device and the flow rate of the UVC sterilization module by multiples.

[0071] Alternatively, multiple UVC sterilization devices may be connected in series to form a second module, and then the multiple second modules may be used in parallel, which can also increase the sterilization capability of the UVC sterilization device and the flow rate of the UVC sterilization module by multiples.

[0072] On this basis, the gaps between the multiple UVC sterilization devices can be filled with heat dissipation medium to improve the overall heat dissipation capacity of the UVC sterilization module.

[0073] On this basis, a temperature control device can be set in the UVC sterilization module to detect whether a temperature abnormality occurs in each UVC sterilization device, so that the UVC sterilization module stops working.

[0074] On this basis, a water flow sensing device can be set in the UVC sterilization module. The water flow sensing device can be set at the input port of the bacteria-carrying medium of the entire UVC sterilization module to avoid repeated detection and reduce the production cost of the entire UVC sterilization module.

[0075] On this basis, due to Fig.10 Multiple UVC sterilization devices are arranged in parallel along the flow direction of the bacterial medium.
