Description

Technical Field

[0001] This utility model belongs to the field of drinking water sterilization technology, and in particular relates to a flow-through sterilizer. Background Technology

[0002] As people's living standards continue to improve, their requirements for the hygiene of their environment have become more stringent, especially regarding water quality, which is directly related to health. As an essential resource in daily life, the safety and hygiene of drinking water are particularly crucial. Therefore, the effective elimination of bacteria, viruses, and microorganisms in water is of paramount importance. Today, flow-through ultraviolet sterilization modules are widely used in the water treatment field, becoming a highly efficient and reliable technology. They can effectively kill harmful microorganisms in water, ensuring water safety and cleanliness, protecting people's drinking water hygiene, and serving as an important safeguard for water purification.

[0003] Existing flow-through sterilizers are difficult to assemble, have complex internal structures, numerous components, and are troublesome to install, resulting in high production costs. When it is necessary to change the length to adapt to different flow rates, the entire system needs to be redesigned or the entire model needs to be replaced, which is quite inconvenient. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flow-through sterilizer, comprising:

[0005] A quartz tube is a hollow tube.

[0006] Sealing end: Both ends of the quartz tube are sealed with sealing ends;

[0007] A bracket is fitted onto a quartz tube, with both ends of the bracket fixedly connected to two sealing ends, and the bracket has the same horizontal cross-section from top to bottom;

[0008] A circuit board is fixedly mounted on the outside of the bracket, and several germicidal lamps are mounted on the circuit board;

[0009] The bracket has several mounting slots on its outer side that correspond to the positions of the germicidal lamps, and the germicidal lamps are located in the mounting slots.

[0010] Furthermore, it also includes:

[0011] A reflective film is fitted onto a quartz tube, and the support is fitted onto the reflective film;

[0012] The reflective film has an opening corresponding to the position of the mounting groove.

[0013] Furthermore, the inner surface of the quartz tube is coated with a reflective layer.

[0014] Furthermore, thermal grease is applied between the bracket and the circuit board.

[0015] Furthermore, the outer surface of the bracket has multiple planes, and a circuit board is disposed on each of the planes.

[0016] Furthermore, it also includes:

[0017] The outer casing is fitted onto the outside of the bracket;

[0018] The two sealing ends press against both ends of the outer shell, and the horizontal cross-section of the outer shell is the same from top to bottom.

[0019] Furthermore, it also includes:

[0020] The stabilizing bar is fixedly installed on the outside of the bracket;

[0021] The housing has a slot that matches the stabilizing bar.

[0022] When the outer shell is fitted onto the outside of the bracket, the stabilizing strip is located inside the slot.

[0023] Furthermore, the surface of the outer casing is formed with a plurality of spaced protrusions.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. By setting up a support with the same horizontal cross-section from top to bottom, sterilizers of different lengths can be adapted to different flow rates. At the same time, the inner ring of the support is in close contact with the quartz tube, and the support is made of metal, which provides better heat dissipation for the circuit board.

[0026] 2. By setting up a reflective film, the sterilization effect and the light irradiation effect are improved, while the ultraviolet light of the germicidal lamp is not affected.

[0027] 3. The reflective layer has a notch, allowing the ultraviolet light from the germicidal lamp to enter. The light entering the quartz tube is reflected by the reflective layer, resulting in a diffuse reflection effect and thus a better sterilization effect.

[0028] 4. By applying thermal grease, the heat conduction efficiency is improved, and the micro-gaps between the surfaces of the circuit board and the bracket are filled, significantly improving the heat transfer efficiency, effectively reducing the temperature of the circuit board, reducing failures or performance degradation caused by overheating, and increasing the service life of the circuit board.

[0029] 5. By setting multiple planes for mounting circuit boards, multiple circuit boards can be installed, allowing the germicidal lamp to irradiate the quartz tube from multiple angles and in all directions, resulting in a stronger overall sterilization effect and avoiding dead corners.

[0030] 6. The outer casing protects the bracket and circuit board. The casing has the same horizontal cross-section from top to bottom, which allows for the cutting of multiple sterilizers of different lengths during production, thus reducing production costs.

[0031] 7. The stabilizing bar and the slot are designed to fit together. During installation, the slot of the outer shell can be aligned with the stabilizing bar of the bracket and inserted to fit the outer shell onto the bracket. This fixes the relative position between the outer shell and the bracket, making the outer shell more stable during installation and making installation convenient.

[0032] 8. The protruding strips provide an anti-slip effect when picking it up. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings indicate similar items, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings. Example 1

[0042] This embodiment provides a flow-through sterilizer, including:

[0043] Quartz tube 1, which is a hollow tube;

[0044] Sealing end 2: Both ends of the quartz tube 1 are sealed with sealing end 2;

[0045] The bracket 3 is sleeved on the quartz tube 1. Both ends of the bracket 3 are fixedly connected to two sealing ends 2. The horizontal cross-section of the bracket 3 is the same from top to bottom.

[0046] Circuit board 4 is fixedly installed on the outside of bracket 3, and a plurality of germicidal lamps 5 are provided on circuit board 4;

[0047] Mounting slots 6 are provided on the outer side of the bracket 3, with a plurality of mounting slots 6 corresponding to the positions of the germicidal lamps 5, and the germicidal lamps 5 are located in the mounting slots 6.

[0048] In this technical solution, the sealing end 2 has an interface 14 for connecting to one end of the quartz tube 1. A sealing gasket is provided inside the interface 14. The sealing end 2 and the quartz tube 1 are sealed together by the sealing gasket. At the same time, both sealing ends 2 have flow ports 15. The drinking water transported by the pipeline enters the quartz tube 1 from one flow port 15 and flows out from the other flow port 15. This utility model is used to sterilize the water flowing through the quartz tube 1.

[0049] Multiple C-shaped strips 16 are provided on the outer side of the bracket 3, and the sealing end 2 is fixedly connected to the C-shaped strips 16 by screws.

[0050] The circuit board 4 is electrically connected to a wire 17, which passes through one of the sealed ends 2 and extends outward. The end of the wire 17 has an electrical plug (not shown in the figure). In actual use, the electrical plug is connected to the socket so that the wire 17 is energized to supply power to the circuit board 4 and the germicidal lamp 5, thereby causing the germicidal lamp 5 to emit ultraviolet light.

[0051] The ultraviolet light emitted by the germicidal lamp 5 shines through the mounting groove 6 onto the quartz tube 1, thereby sterilizing the water flowing through the quartz tube 1.

[0052] In this embodiment, the bracket 3 is made of metal, and the outer surface of the quartz tube 1 can be tightly attached to the inner ring of the bracket 3. Since the circuit board 4 generates heat during operation, and the circuit board 4 is fixedly installed on the outside of the bracket 3, the heat generated by the circuit board 4 will be transferred to the bracket 3. At the same time, the metal material of the bracket 3 makes the heat transfer effect better. Since the outer surface of the quartz tube 1 is tightly attached to the inner ring of the bracket 3, the water flowing through the quartz tube 1 will have a heat dissipation effect on the bracket 3, thereby dissipating heat from the circuit board 4, resulting in a good overall heat dissipation effect.

[0053] Circuit board 4 is located on the outside of bracket 3, which facilitates the replacement and maintenance of circuit board 4.

[0054] The support 3 has the same horizontal cross-section from top to bottom, which allows it to be manufactured using profile parts. Furthermore, when different length sterilizers are needed to accommodate different flow rates, the support 3 does not need to be redesigned. Instead, a support 3 of appropriate length can be directly selected and cut to obtain a support 3 that matches sterilizers of different lengths, resulting in lower manufacturing costs and a wider range of compatibility.

[0055] Even if multiple germicidal lamps 5 are used, only multiple holes need to be drilled on the bracket 3, which reduces the production process and makes the production efficiency high.

[0056] Meanwhile, the installation of this utility model is also very convenient. During installation, the bracket 3 is placed on the quartz tube 1, and then the two sealing ends 2 are connected to the quartz tube 1 so that the two ends of the quartz tube 1 are sealed and connected to the two sealing ends 2. Then, the two sealing ends 2 are fixed on the bracket 3 with screws.

[0057] Through this structural design, by setting up a bracket 3 with the same horizontal cross-section from top to bottom, sterilizers of different lengths can be adapted according to different flow rates. At the same time, the inner ring of the bracket 3 is in close contact with the quartz tube 1, and the bracket 3 is made of metal, which provides better heat dissipation for the circuit board 4. Example 2

[0058] This embodiment provides a flow-through sterilizer, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] Furthermore, it also includes:

[0060] The reflective film 7 is sleeved on the quartz tube 1, and the bracket 3 is sleeved on the reflective film 7;

[0061] The reflective film 7 has an opening 8 that corresponds to the position of the mounting groove 6.

[0062] In this embodiment, the inner ring of the reflective film 7 is in close contact with the quartz tube 1, and the inner ring of the bracket 3 is in close contact with the outer ring of the reflective film 7, so as not to affect the heat dissipation effect;

[0063] The light emitted by the germicidal lamp 5 shines into the quartz tube 1 through the opening 8, so that the reflective film 7 does not affect the light transmission effect.

[0064] The ultraviolet light entering the quartz tube 1 is reflected by the reflective film 7, thus creating a diffuse reflection effect, which makes the overall light irradiation effect better and the sterilization effect better.

[0065] Through this structural design, and by setting up a reflective film 7, the sterilization effect and the light irradiation effect are improved, while the ultraviolet light of the germicidal lamp 5 is not affected. Example 3

[0066] This embodiment provides a flow-through sterilizer, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0067] Furthermore, the inner surface of the quartz tube 1 is coated with a reflective layer (not shown in the figure).

[0068] In this technical solution, the reflective layer has a notch (not shown in the figure) to allow the ultraviolet light from the germicidal lamp 5 to enter. The light entering the quartz tube 1 is reflected by the reflective layer, thus forming a diffuse reflection effect, which makes the sterilization effect better. Example 4

[0069] This embodiment provides a flow-through sterilizer, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0070] Furthermore, thermal grease (not shown in the figure) is applied between the bracket 3 and the circuit board 4.

[0071] This structural design, through the application of thermal grease, improves heat transfer efficiency and fills the micro-gaps between the surfaces of the circuit board 4 and the support 3, significantly enhancing heat transfer efficiency, effectively reducing the temperature of the circuit board 4, minimizing malfunctions or performance degradation caused by overheating, and increasing the lifespan of the circuit board 4. Example 5

[0072] This embodiment provides a flow-through sterilizer, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0073] Furthermore, the outer surface of the bracket 3 has multiple planes 9, and each plane 9 is provided with a circuit board 4.

[0074] Through this structural design, multiple planes 9 for mounting circuit boards 4 are set, allowing multiple circuit boards 4 to be set, so that the germicidal lamp 5 can irradiate the quartz tube 1 from multiple angles and in all directions, resulting in a stronger overall sterilization effect and avoiding dead corners. Example 6

[0075] This embodiment provides a flow-through sterilizer, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0076] Furthermore, it also includes:

[0077] The outer casing 10 is fitted onto the outside of the bracket 3;

[0078] The two sealing ends 2 press against both ends of the outer shell 10, and the horizontal cross-section of the outer shell 10 is the same from top to bottom.

[0079] In this technical solution, the outer shell 10 protects the bracket 3 and the circuit board 4. When the two sealing ends 2 are fixed to the bracket 3 with screws, the outer shell 10 is pressed, thereby fixing the outer shell 10.

[0080] Furthermore, the outer shell 10 has the same horizontal cross-section from top to bottom, which allows the outer shell 10 to be manufactured using profile parts during processing. At the same time, when it is necessary to change the sterilizer of different lengths according to different flow rates, the outer shell 10 does not need to be redesigned industrially. Instead, the appropriate length of the outer shell 10 can be directly selected and cut to obtain an outer shell 10 that matches sterilizers of different lengths, resulting in lower manufacturing costs and a wider range of compatibility.

[0081] This structural design, with the outer shell 10, protects the bracket 3 and the circuit board 4. At the same time, the horizontal cross-section of the outer shell 10 is the same from top to bottom, which allows for the cutting of multiple sterilizers of different lengths during production, thus reducing production costs. Example 7

[0082] This embodiment provides a flow-through sterilizer, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0083] Furthermore, it also includes:

[0084] The stabilizing bar 11 is fixedly installed on the outside of the bracket 3;

[0086] When the outer shell 10 is fitted onto the outside of the bracket 3, the stabilizing strip 11 is located inside the slot 12.

[0087] In this technical solution, the stabilizing bar 11 and the slot 12 are designed to work together so that during installation, the slot 12 of the outer shell 10 can be aligned with the stabilizing bar 11 of the bracket 3 and inserted, thereby fitting the outer shell 10 onto the bracket 3 and fixing the relative position between the outer shell 10 and the bracket 3. This makes the outer shell 10 more stable during installation and also makes installation convenient. Example 8
