Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a main frame, a flowing water sterilization body, and a sterilization device. Background Technology

[0002] Ultraviolet (UV) light is widely used in water treatment sterilization due to its superior physical sterilization method. In conventional flowing water sterilization devices, the required UVC (Ultraviolet C, short-wave ultraviolet) light power varies depending on the water flow rate. Higher flow rates require more UVC light sources and thus higher UVC light power. The water flow rate also affects the size and structure of the inlet and outlet nozzles. Some nozzles are straight-through, while others are quick-connect. Different application scenarios lead to different user needs. For manufacturers, meeting these needs requires producing a wide variety of products and stocking numerous types of raw materials, increasing overall costs.

[0003] Conventional flowing water sterilization devices require a certain water pressure resistance. In reality, the water pressure resistance of these devices varies. The standard method for ensuring pressure resistance is to tighten the device with screws or threads on its outer casing. If the device is disassembled and then restored to its original state by the user, there is a risk of reduced pressure resistance or failure, leading to leaks and directly impacting the safety of the user's surrounding environment and property.

Detailed Implementation

[0065] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0066] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connected" should be interpreted broadly. For example, it can refer to 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0067] Throughout the text, the terms “top,” “bottom,” “above,” “below,” and “on top” refer to the relative positions of components of the device, such as the relative positions of the top and bottom substrates within the device. It is understood that the device is multifunctional and independent of its spatial orientation.

[0068] The working surface of this utility model can typically be a plane or a curved surface, and can be inclined or horizontal. For ease of explanation, the embodiment of this utility model is placed on a horizontal surface and used on a horizontal surface, thereby defining "height" and "vertical".

[0069] Example 1

[0070] This embodiment discloses a main frame, which serves as the core structural foundation of the flowing water sterilization body, such as... Figures 1-3 As shown, the two ends of the main frame 1 are respectively provided with a first connecting part 11 and a second connecting part 12. The first connecting part 11 is configured to be able to connect with at least the water outlet or water inlet. The second connecting part 12 is configured to be able to connect with the water outlet or water inlet at least simultaneously with the first connecting part 11. That is, the second connecting part can also be connected with the water outlet or water inlet at the same time as the first connecting part is connected with the water outlet or water inlet. In other words, the flowing water sterilization body is connected with the water outlet (or water inlet) through the first connecting part and the second connecting part to strengthen the connection strength between the main frame and the water outlet or water inlet.

[0071] The main frame 1 is also provided with a plurality of sterilization assembly parts 13, which are configured to be at least capable of detachably assembling sterilization elements.

[0072] The main frame of this utility model improves the connection strength with the water outlet and water inlet components by setting a first connecting part and a second connecting part at each end of the main frame, thereby enhancing the pressure-bearing effect of the sterilization device. Furthermore, the multiple sterilization assembly parts allow for selection of the number of sterilization elements to be assembled, effectively controlling the sterilization effect of the flowing water sterilization body. This means that an appropriate number of sterilization elements can be assembled according to the usage scenario and water flow rate, avoiding resource waste caused by too many sterilization elements and insufficient sterilization effect caused by too few sterilization elements.

[0073] According to one embodiment of the present invention, the two ends of the main frame 1 are a first end and a second end, respectively. The first end is provided with a first connecting portion 11, and the second end is provided with a first connecting portion 11. The sterilization assembly portion 13 is located between the first connecting portion of the first end and the first connecting portion of the second end, and extends from the first end connecting portion along the length direction of the main frame 1 (i.e., the direction OO of the center line of the main frame) towards the first connecting portion of the second end. It can extend directly to the second connecting portion of the second end, or it can extend to the vicinity of the second connecting portion of the second end (e.g., ...). Figure 1 As shown), multiple sterilization assembly parts 13 are arranged in parallel between the first connecting parts at both ends. The second connecting part 12 is located between the two first connecting parts 11 (i.e., the first connecting part at the first end and the first connecting part at the second end), and is close to their respective first connecting parts. That is, the second connecting part at the first end (i.e., the end including the first end) is close to the first connecting part at the first end, and the second connecting part at the second end (i.e., the end including the second end) is close to the first connecting part at the second end. The second connecting part 12 is located in the gap between the sterilization assembly parts 13 to avoid the second connecting part affecting the assembly of the sterilization element.

[0074] To improve the assembly stability and connection strength of the flowing water sterilization body, multiple second connecting parts 12 are provided at both ends of the main frame, and the second connecting parts 12 at both ends are arranged opposite each other. That is, multiple sets of oppositely arranged second connecting parts 12 are provided between the first connecting part 11 at the first end and the first connecting part 11 at the second end. The two oppositely arranged second connecting parts in each set are respectively close to the first connecting part at the first end and the first connecting part at the second end. The two oppositely arranged second connecting parts 12 at both ends constitute a set of second connecting parts. Preferably, the number of sets of second connecting parts is the same as the number of sterilization assembly parts 13, that is, the number of second connecting parts at each end of the main frame is the same as the number of sterilization assembly parts, and the sterilization assembly parts and second connecting parts are arranged alternately (e.g., Figure 1 and Figure 2 As shown in the diagram, multiple sterilization assemblies and multiple sets of second connecting parts are arranged alternately. In this embodiment, the main frame includes four sterilization assemblies and four sets of second connecting parts, that is, eight second connecting parts arranged in pairs opposite each other.

[0075] The first connecting part 11 is preferably a detachable connecting part, which can be a snap-fit ​​connecting part, a threaded connecting part, etc. In this embodiment, the first connecting part is preferably a threaded connecting part with the best connection strength.

[0076] The second connecting part 12 is preferably a snap-fit ​​connecting part with a self-locking function, and its material has a certain degree of elasticity to avoid affecting the connection between the water outlet or water inlet part and the first connecting part. In this embodiment, the second connecting part 12 is a self-locking claw, and its material is food-grade PC (Polycarbonate) or food-grade POM (Polyoxymethylene) material, etc.

[0077] The self-locking claw includes an inclined plate portion 121 and a locking portion 122. One end of the inclined plate portion 121 is connected to the side wall of the main frame 1, and the other end of the inclined plate portion 121 is connected to the locking portion 122. The inclined plate portion 121 is inclined outward (away from the side wall) and towards the center (central area of ​​the side wall) from the connection point with the side wall of the main frame 1, and the angle between the inclined plate portion 121 and the side wall of the main frame 1 is α, 20°≤α≤70°, preferably α=45°. The locking portion 122 is parallel to the center line OO of the main frame. In this embodiment, the side wall of the main frame 1 is shaped similarly to the side wall of a polygonal prism, that is, each side wall is parallel to the center line OO, and the locking portion 122 is parallel to the side wall of the main frame 1.

[0078] The main frame 1 is also provided with an assembly channel 101 that runs through its center line OO. The assembly channel extends from one end of the main frame to the other end, that is, the assembly channel 101 extends from the first end to the second end. The first end and the second end are provided with through holes that communicate with the assembly channel 101. One of the through holes is a water inlet hole and the other through hole is a water outlet hole.

[0079] The sterilization assembly part 13 is provided with an electrical connection hole 131, a plurality of positioning holes 132 and a plurality of light source holes 133. The electrical connection hole 131 is located at one end of the sterilization assembly part 13 and communicates with the assembly channel 101 to enable electrical connection between the sterilization element and electrical devices such as power supply. Preferably, the side of the electrical connection hole 131 away from the center of the sterilization element extends outward in an arc shape to form an arc-shaped portion 131a. When the sterilization element is configured to be assembled into the sterilization assembly part, it will not cover the arc-shaped portion 131a. That is, when the sterilization element is configured to be assembled into the sterilization assembly part, the arc-shaped portion 131a can be exposed so that the sterilization element can be disassembled through the arc-shaped portion 131a. The light source holes 133 are arranged in an array between the two ends of the sterilization assembly part, and the light source holes communicate with the assembly channel 101. The light source holes cooperate with the sterilization light source of the sterilization element. On the one hand, the sterilization light source embedded in the light source hole can protect the sterilization light source. On the other hand, the communication between the light source hole and the assembly channel facilitates the entry of the sterilization light waves emitted by the sterilization light source into the assembly channel to sterilize the flowing water in the assembly channel. In this embodiment, the light source holes 133 are arranged in a vertical row, and there are three light source holes 133. The fixing posts 132 are located at both ends of the light source hole array and are used to fix the sterilization element.

[0080] The main frame 1 is a one-piece molded structure, that is, the main frame 1 is made of one piece of molded material, and the material of the main frame 1 is food-grade PC material or food-grade POM material, etc.

[0081] It should be noted that the connection structure between the two ends of the main frame 1 and the water outlet and water inlet components is the same, that is, the two ends can be connected to either the water outlet or the water inlet component, without distinguishing between the water inlet end and the water outlet end.

[0082] Example 2

[0083] This embodiment discloses a flowing water sterilization body, such as Figures 4-7 As shown, it includes:

[0084] The main frame 1 provided in Example 1;

[0085] At least one sterilization element 2 is detachably assembled to the sterilization assembly 13. The number of sterilization elements 2 is less than or equal to the number of sterilization assembly 13. In practical applications, the seller can assemble a suitable number of sterilization elements according to the customer's sterilization needs.

[0086] Transparent tube 3 is located in the assembly channel of the main frame 1, and is intended to serve as a pipe for carrying flowing water;

[0087] The heat dissipation sleeve 4 is configured to be able to be fitted on the outside of the main frame 1 on which the sterilization element 2 is assembled, so as to dissipate the heat generated by the operation of the sterilization element 2 to the outside, and to avoid the high heat generated by the operation of the sterilization element 2 from affecting its lifespan as much as possible.

[0088] The sterilization element 2 is provided with a plurality of sterilization light sources 21. The sterilization light sources 21 are configured to emit at least ultraviolet light waves with sterilization function. For example, the sterilization light source is a UVC light source. The sterilization light sources 21 cooperate with the light source holes 133 of the sterilization assembly part. The cooperation here includes that the shapes, arrangements and numbers of the two are compatible. That is, the sterilization light sources 21 are arranged in an array between the two ends of the sterilization element, and the sterilization light sources can be embedded in the light source holes 133 so that the emitted sterilization light waves can enter the transparent tube of the assembly channel to sterilize the water flow in the transparent tube. In this embodiment, the sterilization light sources 21 are arranged in a vertical row, and the number of sterilization light sources 21 is three.

[0089] The sterilization element 2 is also provided with fixing holes 22 that cooperate with the fixing posts 132 of the sterilization assembly part. The cooperation here also includes that the shapes, arrangements and numbers of the two are compatible. The fixing posts are inserted into the fixing holes to fix the sterilization element. In this embodiment, there are two fixing holes 22, which are located at both ends of the sterilization light source array.

[0090] It should be noted that the working principle of the sterilization element 2 and the electrical connector connected to it are common knowledge and not the innovation of this utility model, so they will not be described in detail here.

[0091] The heat dissipation sleeve 4 can at least cover the portion of the sterilization element 2 equipped with the sterilization light source 21 to ensure heat dissipation. In this embodiment, the length of the heat dissipation sleeve 4 (the length in the direction of the center line OO) is greater than the length of the array of sterilization light sources 21, less than the length of the sterilization element, and less than the distance between the second connecting parts at both ends of the main frame. That is, the heat dissipation sleeve is located between the second connecting parts at both ends of the main frame to avoid affecting the connection between the main frame and the water outlet and water inlet components.

[0092] For ease of assembly, the heat dissipation sleeve 4 includes multiple heat dissipation fins 41, meaning the heat dissipation sleeve 41 is formed by multiple heat dissipation fins 41. The heat dissipation fins 41 are adhesively applied to the outside of the main frame housing the sterilization element, and the multiple heat dissipation fins are then assembled to form the heat dissipation sleeve; alternatively, the heat dissipation fins 41 are detachably connected, with multiple heat dissipation fins surrounding the outside of the main frame housing the sterilization element, and the multiple heat dissipation fins then assembled to form the heat dissipation sleeve, facilitating the assembly and subsequent maintenance of the flowing water sterilization body. For example, the heat dissipation fins can be detachably connected via snap-fit ​​connections. In this embodiment, the heat dissipation sleeve 4 includes two semi-annular wall-shaped heat dissipation fins, which are adhesively applied to the outside of the main frame housing the sterilization element.

[0093] The heat sink is made of aluminum, which has good heat dissipation performance and is lightweight.

[0094] The transparent tube is made of quartz glass. To improve sterilization efficiency, a reflective film is applied to the outside of the transparent tube. The reflective film is made of PTFE (polytetrafluoroethylene). The ultraviolet rays emitted by the sterilization light source pass through the quartz glass and are continuously reflected inside the reflective film, improving the utilization rate of ultraviolet rays and thus improving sterilization efficiency.

[0095] Example 3

[0096] This embodiment discloses a flowing water sterilization device, such as... Figures 8 to 14 As shown, it includes:

[0097] The flowing water sterilization body provided in Example 2;

[0098] The water outlet 5 is configured to be connected to one end of the flowing water sterilization body;

[0099] The water inlet 6 is configured to be connected to one end of the flowing water sterilization body;

[0100] Both the water outlet component 5 and the water inlet component 6 are provided with a first assembly part 7 and a second assembly part 8 that cooperate with the first connecting part 11 and the second connecting part 12, respectively. That is, the water outlet component 5 is provided with a first assembly part 7 that cooperates with the first connecting part 11 and a second assembly part 8 that cooperates with the second connecting part, and the water inlet component 6 is provided with a first assembly part 7 that cooperates with the first connecting part 11 and a second assembly part 8 that cooperates with the second connecting part. Here, "cooperation" refers to the cooperation of the connecting structures. For example, when the first connecting part is a threaded connecting part, the first assembly part is a channel that cooperates with the threaded connecting part; when the second connecting part is a self-locking claw, the second assembly part is a self-locking groove. That is, when the water inlet component or the water outlet component is assembled to the flowing water sterilization body, the water inlet component or the water outlet component is first put on one end of the flowing water sterilization body, and then the water inlet component or the water outlet component is rotated to tighten the threaded channel and the threaded connecting part. When the thread is tightened to the bottom, the self-locking claw is just embedded in the self-locking groove. Since the self-locking claw is made of elastic material, it will not affect the threaded connection.

[0101] The water outlet and water inlet components can be configured with multiple models to suit the needs of different users, such as... Figure 8 In the middle, there are type A inlet and type A outlet components. Figure 9 Type B inlet and Type B outlet components, Figure 10The system includes Type C inlet and Type C outlet components. Types A and B are external connectors, while Type C is an internal connector. The inlet and outlet flow rates of Type A are lower than those of Type B. This allows manufacturers to produce only different models of inlet and outlet components, while other components only require one model. Sellers can then assemble the required number of inlet, outlet, and sterilization elements onto the flowing water sterilization device based on customer needs. This eliminates the need for manufacturers to produce different models of flowing water sterilization devices. This simplifies the manufacturer's process, reduces costs, and shortens the delivery cycle. It also increases the seller's flexibility in fulfilling orders, avoids unsold large items, and reduces delivery risks.

[0102] A waterproof rubber ring 9 is provided between the first assembly part 7 and the first connecting part 11 to improve the sealing connection between the transparent tube and the water outlet and water inlet parts, and to prevent water leakage from the flowing water sterilization device.

[0103] The second assembly part and the second connecting part of this utility model adopt a self-locking snap-fit ​​structure, which can not only improve the pressure resistance of the flowing water sterilization device, but also prevent the user end from disassembling it, reducing the safety hazards that the user end may have to disassemble it, and achieving the effect of making it difficult for the user end to disassemble.

[0104] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
