Description

Technical Field

[0001] This utility model relates to the technical field of pipeline disinfection and sterilization equipment, specifically to a tubular module with controllable sterilization. Background Technology

[0002] In recent years, pipeline UVC sterilization devices typically use UV-C band ultraviolet light to destroy the DNA / RNA structure of microorganisms, achieving highly efficient inactivation with a sterilization rate of over 99%. They are suitable for dynamic water flow treatment, such as municipal water supply, swimming pool water, and secondary water supply.

[0003] However, existing UVC lamps used in pipeline UVC sterilization devices generate significant heat due to prolonged operation, leading to reduced lifespan. Furthermore, current technologies often employ water flow sensors to control the UVC lamps' operation, which are typically separate components requiring connection to a pipe module. This increases the number of sealing structures in the pipeline, raising the risk of leaks, and also complicates the design and manufacturing process. Therefore, we propose a novel controllable sterilization tubular module. Utility Model Content

[0022] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0023] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example 1:

[0026] Please see Figure 1-3 This utility model provides a technical solution: a controllable sterilization tubular module, including: a first connection port 5, a second connection port 6, and a sterilization component 2. The sterilization component 2 is externally provided with a UVC lamp strip bracket 1 and a UVC lamp strip 21. The second connection port 6 is fixedly connected to the outlet end of the sterilization component 2, and the first connection port 5 is fixedly connected to the inlet end of the sterilization component 2. The sterilization component 2 is internally provided with a sensing sensor 3, and the sensing sensor 3 is located in the inner cavity of the sterilization component 2. The sensing sensor 3 includes a mounting shell 31, a magnetic rotor 32, and a sensing controller 33 (which may be a sensing PCB board, etc.). The magnetic rotor 32 is rotatably disposed in the inner cavity of the mounting shell 31, and the sensing controller 33 is electrically connected to the UVC lamp strip 21.

[0027] It should be noted that in one connection scheme, the external interface of the first connection port 5 and / or the second connection port 6 is detachably connected to an independent first adapter 7 or second adapter 8 (the first adapter 7 and the second adapter 8 can be threaded connectors, quick connectors, etc.); in another scheme, the first connection port 5 and / or the second connection port 6 are integrally formed with an adapter structure. The first scheme will be used as an example below.

[0028] When the sterilization process begins, the medium to be sterilized (which can be gas or liquid) enters the first connection port 5 from the first adapter 7, is sterilized by the sterilization component 2, and finally flows into the second adapter 8 from the second connection port 6 and then flows out.

[0029] Specifically, such as Figure 3 As shown, the mounting housing 31 is located inside the sterilization component 2. The sensor controller 33 is located inside the mounting housing 31 in the area that can sense the rotation of the magnetic rotor 32, and the sensor controller 33 is fixedly connected to the bottom of the inner cavity of the UVC lamp strip bracket 1. When the sterilization operation begins, the medium to be sterilized (which can be gas or liquid) enters the first connection port 5 from the first adapter 7. It first passes through the mounting housing 31, and the flowing medium will drive the magnetic rotor 32 to rotate, thereby changing its magnetic poles. The sensor controller 33 receives the signal of the change in the magnetic poles of the magnetic rotor 32, and can then control the UVC-LED on the UVC lamp strip 21 to be powered. The UVC-LED lamp beads light up, and the sterilization component 2 performs sterilization. When the sterilization operation ends, the water flow no longer passes through the inner cavity of the mounting housing 31. When the magnetic rotor 32 stops rotating and the magnetic poles do not change, the induction controller 33 does not receive a signal indicating a change in the magnetic poles of the magnetic rotor 32, and therefore stops supplying power to the UVC-LED beads on the UVC lamp strip 21. The UVC-LED beads are turned off, reducing the excessive heat generated by the UVC-LED beads due to prolonged operation, which could lead to overheating. This effectively increases the lifespan of the UVC-LED beads and thus extends the product's usage time. At the same time, by placing the sensing sensor 3 at one end of the sterilization component 2, the sensing sensor 3 is integrated into the device, reducing the need for a sealed pipeline structure and effectively avoiding the risk of water leakage. This makes the device structure more streamlined, reduces raw materials and processes, and effectively increases production capacity.

[0030] The sterilization component 2 also includes a UVC light-transmitting tube 22 (specifically, a tube that can transmit UVC light, such as a quartz tube, which can transmit UVC light) and a UVC reflector 23 (a medium that can reflect UVC light, such as Teflon). A UVC light strip 21 is fixedly connected to one side of the inner cavity of the UVC light strip bracket 1. The UVC reflector 23 is sleeved on the outside of the UVC light-transmitting tube 22. The UVC light strip 21 is equipped with UVC-LED beads (the number of beads depends on the situation, but is at least one; in this application, eight beads are provided, and the number can be increased depending on the flow rate). The UVC reflector 23 has a light-transmitting portion corresponding to the position of the UVC-LED beads on the UVC light strip 21. The mounting shell 31 is located within the UVC light strip 21. Inside the light-transmitting tube 22, the UVC reflector 23 and the UVC light-transmitting tube 22 are located below the UVC lamp strip 21, which facilitates diffuse reflection of the light emitted by the UVC lamp strip 21, increases the number of diffuse reflections of UVC light inside the UVC light-transmitting tube 22, and improves sterilization efficiency. When sterilization begins, the UVC-LED lamp beads are turned on by the sensor 3, and sterilization can be effectively carried out through the light transmission and diffuse reflection of the UVC reflector 23 and the UVC light-transmitting tube 22. When there is no water flow, the magnetic rotor 32 inside the mounting shell 31 does not rotate, and the sensor 3 turns off the UVC-LED lamp beads, reducing the heat generated by the UVC-LED lamp beads and thus increasing their lifespan.

[0031] It should be noted that the light-transmitting part is an opening that penetrates the body of the UVC reflector 23. This opening is a hole corresponding to the UVC-LED lamp bead. The shape of the opening can be selected and optimized according to the optical design requirements and processing technology, and is not limited to a specific shape. For example, it can be a circular hole or a square hole that is precisely aligned with the position of a single lamp bead; or it can be an elongated hole that extends along the direction of the lamp strip and covers a group of lamp beads. This flexibility in opening different shaped openings on the reflector allows this design to adapt to different light emission angles and light field distribution requirements in order to achieve the best comprehensive sterilization effect.

[0032] Furthermore, the correspondence between UVC-LED beads and openings can be flexibly set according to the aforementioned optical requirements. It can adopt a precise "one-to-one" correspondence, where one bead faces one independent opening; or it can adopt an integrated "one-to-many" or "many-to-one" correspondence, where a larger opening simultaneously corresponds to and covers multiple adjacent beads. This approach helps to form a more uniform and wider illumination area.

[0033] It should be noted that the UVC reflector 23 is a tubular component or a notched cylindrical structure formed by rolling up sheet-like reflective material. The physical form of the UVC reflector 23 itself also has design flexibility. First, it can be a pre-formed, seamless tubular component with a stable structure and high reflection efficiency. Second, it can also be a notched cylindrical structure formed by rolling up sheet-like reflective material (such as aluminized film, Teflon, etc.). This rolled cylindrical structure reduces manufacturing difficulty and cost while ensuring the reflection function. Moreover, its natural notched structure can be used as part of the light transmission part or provide a channel for heat dissipation. The above two forms can be selected according to the specific cost control, production efficiency and optical performance requirements.

[0034] Specifically, such as Figure 2 As shown, the induction controller 33 integrates a status indicator light. The bottom of the inner cavity of the UVC lamp strip bracket 1 has a through hole, and a light guide column 10 is sealed and fixedly connected to the inner cavity of the through hole to guide the light of the status indicator light to the outside. When the UVC lamp strip 21 is turned on to carry out sterilization, the status indicator light on the induction controller 33 is lit and shines through the light guide column 10 to the outside of the UVC lamp strip bracket 1. When the sterilization is completed and the UVC lamp strip 21 is turned off, the status indicator light on the induction controller 33 is turned off, and the light of the indicator light cannot be seen from the light guide column 10, so that the staff can observe the working status of the UVC lamp strip 21 in a timely manner.

[0035] It should be noted that the status indicator is configured to display the first color (e.g., blue) when the sensor controller 33 is powered on but not running, the second color (e.g., green) when the device is running normally for sterilization, and the third color (e.g., red) when a device malfunction is detected. The sensor 3 can also determine whether the UVC-LED beads of the UVC light strip 21 are working properly by detecting the current and voltage signals passing through the UVC light strip 21. If they are not working properly, the status indicator will display the third color.

[0036] The UVC lamp strip bracket 1 is fixedly connected at both ends to the first connection port 5 and the second connection port 6, respectively. The first connection port 5 is sealed to the UVC lamp strip bracket 1 and the UVC light-transmitting tube 22 with waterproof O-rings 4, and the second connection port 6 is also sealed to the UVC lamp strip bracket 1 and the UVC light-transmitting tube 22 with waterproof O-rings 4. Multiple waterproof O-rings 4 are provided to effectively ensure the sealed connection between the various parts of the device, effectively preventing loosening and leakage during the sterilization process. A power cord 9 is threaded through the second connection port 6. The connection point between the power cord 9 and the second connection port 6 is fixed and sealed with sealant. After the power cord 9 passes through the wire hole, it is fixed with sealant to prevent water from entering the cavity through the power cord hole. The power cord 9 is electrically connected to the components in the sterilization assembly 2 and the sensor 3.

[0037] It should be noted that the UVC light strip 21 is fixedly connected to one side of the inner cavity of the UVC light strip bracket 1, and the LED beads are mounted on the UVC light strip 21. This structural design allows the heat generated by the UVC light strip 21 during operation, especially by the UVC-LED beads on it, to be efficiently conducted to the UVC light strip bracket 1 through the tightly contacted mounting interface. Since the UVC light strip bracket 1 is made of metal and has good thermal conductivity, it acts as an efficient heat dissipation carrier, rapidly dissipating heat. More importantly, during the module's operation, the medium to be sterilized (such as…) Water or air continuously flows through the UVC light-transmitting tube 22, which is tightly connected to the UVC lamp strip bracket 1. The flowing medium and the UVC lamp strip bracket 1 continuously exchange heat through the tube wall, thereby continuously carrying away the heat generated by the UVC-LED lamp beads. This active heat dissipation path, consisting of "lamp beads → lamp strip → metal bracket → flowing medium", effectively reduces the core operating temperature of the UVC-LED lamp beads and avoids the problem of UVC light attenuation caused by long-term high-temperature operation, thus significantly improving the stability and lifespan of the UVC-LED lamp beads.

[0038] It should be noted that the above-mentioned fixed connections include bolted connections, threaded connections, adhesive connections, and other detachable connection methods.

[0039] Example 2:

[0040] Please see Figure 1-4 In this embodiment,

[0041] The UVC light strip bracket 1 is fitted with a housing 12, and both ends of the housing 12 are sealed and fixedly connected to the first connection port 5, the second connection port 6, and the UVC light strip bracket 1, respectively, thus achieving a simple and beautiful overall structure. An indicator light 11 is fixedly connected to one side of the first connection port 5. The indicator light 11 is electrically connected to the induction controller 33. The indicator light 11 is configured to display a first color (e.g., blue) when the module is powered on but not running, a second color (e.g., green) when the equipment is running normally for sterilization, and a third color (e.g., red) when a fault is detected. At this time, by placing the indicator light 11 on one side of the first connection port 5, the opening and closing of the UVC light strip 21 can be observed more intuitively, making it easier for staff to control the entire sterilization process. The above-mentioned fixed connections are bolted connections, adhesive connections, and other detachable connection methods.

[0042] It should be noted that this utility model is a tubular module for controllable sterilization. When sterilization begins, the medium to be sterilized (which can be gas or liquid) enters the first connection port 5 from the first adapter 7. Through the mounting shell 31, the medium flowing through it will drive the magnetic rotor 32 to rotate, thereby changing the magnetic poles. The induction controller 33 receives the signal of the change in the magnetic poles of the magnetic rotor 32, and can control the UVC-LED beads on the UVC lamp strip 21 to be powered on and turn on. Through the light transmission and reflection of the UVC reflector 23 and the UVC light-transmitting tube 22, the medium carrying bacteria can be effectively sterilized. The sterilized medium finally flows into the second adapter 8 from the second connection port 6 and finally flows out. At this time, the status indicator light on the induction controller 33 is lit and shines through the light guide column 10 to the outside of the UVC lamp strip bracket 1.

[0043] When the sterilization process is complete, the bacteria-carrying medium no longer passes through the inner cavity of the mounting shell 31, the magnetic rotor 32 stops rotating, the magnetic poles do not change, and the induction controller 33 does not receive a signal of magnetic pole change from the magnetic rotor 32. Therefore, it no longer supplies power to the UVC-LED beads on the UVC lamp strip 21. At this time, the status indicator light on the induction controller 33 is turned off, and the status indicator light cannot be seen from the light guide column 10. The staff can then know that the sterilization process is complete.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
