Description

Technical Field

[0001] This utility model relates to the technical field of water treatment, and in particular to a flow-through ultraviolet sterilizer. Background Technology

[0002] In water treatment, prolonged immersion can produce harmful substances and promote bacterial growth, necessitating water sterilization. Current technology typically employs flow-through ultraviolet (UV) sterilizers, which irradiate flowing water with ultraviolet light. Existing flow-through sterilizers include a housing, a glass tube installed within the housing, and a UV lamp inside the glass tube. Water flows through the cavity between the glass tube and the housing. To improve water tightness, one end of the glass tube is closed, and the other is open. During installation, the UV lamp is inserted into the glass tube from the open end, while the closed end abuts against the inner wall of the housing for fixation. To prevent the glass tube from shaking and breaking, a silicone sleeve is used between the closed end of the glass tube and the housing for elastic contact. However, in actual assembly, due to the considerable length of the glass tube, the closed end is difficult to accurately engage with the silicone sleeve during insertion, causing the glass tube to tilt. Utility Model Content

[0003] The purpose of this utility model is to provide a flow-through ultraviolet sterilizer to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0005] This utility model provides a flow-through ultraviolet sterilizer, comprising:

[0006] A housing assembly includes a water housing, the water housing having an inlet, an outlet and an insertion port, the insertion port being located at one end of the water housing;

[0007] The light-emitting component includes at least one ultraviolet lamp tube and a glass tube with a blind tube structure. One end of the glass tube is a closed end and the other end is an open end. The closed end is inserted into the water housing from the outside to the inside through the insertion port. A sterilization and disinfection water chamber is formed between the glass tube and the water housing. The sterilization and disinfection water chamber is connected to the water inlet and the water outlet respectively. The ultraviolet lamp tube is fitted inside the glass tube.

[0008] The fixing assembly includes a fixing frame, a silicone sleeve, and a guide frame. The fixing frame is located inside the end of the water shell away from the insertion port. The silicone sleeve and the guide frame are located on the side of the fixing frame facing the insertion port. The silicone sleeve has a positioning groove on the side facing the insertion port. The guide frame has a guide channel located on the side of the positioning groove facing the insertion port. The diameter of the guide channel gradually decreases from the insertion port toward the fixing frame to guide the closed end to engage with the positioning groove.

[0009] A sealing assembly is disposed between the glass tube and the insertion port.

[0010] The beneficial effects of this flow-through ultraviolet sterilizer are:

[0011] In use, the water to be treated flows sequentially through the inlet, the sterilization and disinfection chamber, and the outlet. While passing through the sterilization and disinfection chamber, the water is irradiated with ultraviolet light by a UV lamp to achieve sterilization and disinfection. During assembly, the closed end of the glass tube is inserted into the water housing through the insertion port. Because the diameter of the guide channel gradually decreases from the insertion port towards the fixing frame, the closed end of the glass tube can be easily inserted into the guide channel of the guide frame. Guided by the guide channel, the closed end quickly and accurately aligns with the positioning groove of the silicone sleeve, achieving elastic fixation of the closed end and providing a buffering and vibration-damping effect for the glass tube. Then, a sealing assembly seals and fixes the glass tube to the insertion port. This invention guides the installation of the glass tube through the guide channel in the guide frame, while also providing reinforcement, effectively preventing tilting and shaking of the glass tube during installation and transportation.

[0012] As a further improvement to the above technical solution, the fixing frame is provided with an installation groove on the side facing the insertion port, the silicone sleeve is installed in the installation groove, and the guide frame is provided with a sleeve ring fixed between the installation groove and the water shell.

[0013] As a further improvement to the above technical solution, the end of the sleeve facing the insertion port is provided with a plurality of guide blocks spaced apart circumferentially, and the plurality of guide blocks are provided with inclined guide slopes on the side near the axis of the sleeve, and the plurality of guide slopes form the guide channel.

[0014] As a further improvement to the above technical solution, a guide sleeve is provided between the multiple guide blocks, and the inner peripheral wall of the guide sleeve is a tapered surface structure that smoothly transitions and connects with the guide inclined surface.

[0015] As a further improvement to the above technical solution, the inner peripheral wall of the positioning groove is provided with a plurality of positioning protrusions distributed at intervals along the circumference. The positioning protrusions extend along the axial direction of the positioning groove and are inclined at the end near the insertion port so that the diameter of the groove opening gradually decreases from the insertion port toward the fixing frame.

[0016] The outer periphery of the silicone sleeve is provided with a snap-fit ​​groove that engages with the groove of the mounting groove.

[0017] As a further improvement to the above technical solution, the water outlet is located at the end of the water shell away from the insertion port, and the water inlet is located on the outer peripheral wall of the water shell near the insertion port.

[0018] The fixed frame is provided with a plurality of water passage holes distributed circumferentially, the plurality of water passage holes connecting the water inlet and the water outlet, and the water outlet and the plurality of water passage holes being offset axially.

[0019] As a further improvement to the above technical solution, the water shell includes a hollow tube, a first end cap and a second end cap respectively sealed and fitted to both ends of the tube, the insertion port is provided on the first end cap, the second end cap has an installation groove on the side facing the first end cap, and the fixing bracket is fitted into the installation groove.

[0020] As a further improvement to the above technical solution, at least two support frames are fitted on the outer peripheral wall of the tube.

[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0040] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They 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. Therefore, they should not be construed as limitations on this utility model.

[0041] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0042] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0043] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0044] In the prior art, due to the large length of the glass tube 300, it is difficult for the closed end 310 of the glass tube 300 to accurately engage with the silicone sleeve 600 during the insertion process, which makes the glass tube 300 prone to tilting. Therefore, this utility model proposes a flow-through ultraviolet sterilizer, which can effectively avoid the phenomenon of tilting and shaking of the glass tube 300 during installation and transportation.

[0045] like Figures 1 to 4 As shown, the flow-through ultraviolet sterilizer of this utility model includes a housing assembly, a light-emitting assembly, a fixing assembly, and a sealing assembly.

[0046] like Figure 1 and Figure 3 As shown, the housing assembly includes a water housing 100, which has an inlet 110, an outlet 120 and an insertion port 130, with the insertion port 130 located at one end of the water housing 100.

[0047] like Figure 3As shown, the light-emitting component includes an ultraviolet lamp tube 200 and a glass tube 300. The glass tube 300 is a blind tube structure, with one end of the glass tube 300 being a closed end 310 and the other end being an open end 320. The closed end 310 is inserted into the water housing 100 from the outside to the inside through the insertion port 130. A sterilization and disinfection water chamber 400 is formed between the glass tube 300 and the water housing 100. The sterilization and disinfection water chamber 400 is connected to the water inlet 110 and the water outlet 120, respectively. The ultraviolet lamp tube 200 is sleeved inside the glass tube 300 from the open end 320. During operation, the water to be treated flows sequentially along the water inlet 110, the sterilization and disinfection water chamber 400, and the water outlet 120. When passing through the sterilization and disinfection water chamber 400, the water is irradiated with ultraviolet light by the ultraviolet lamp tube 200.

[0048] The glass tube 300 of this invention is used to protect the ultraviolet lamp tube 200, preventing water from contacting the ultraviolet lamp tube 200, while allowing ultraviolet light to pass through the glass tube 300 to irradiate the flowing water.

[0049] like Figure 3 and Figure 4 As shown, the fixing component of this utility model is used to fix the closed end 310. Specifically, the fixing component of this utility model includes a fixing frame 500, a silicone sleeve 600, and a guide frame 700. The fixing frame 500 is located inside the end of the water shell 100 away from the insertion port 130, while the silicone sleeve 600 and the guide frame 700 are located on the side of the fixing frame 500 facing the insertion port 130. The side of the silicone sleeve 600 facing the insertion port 130 is provided with a positioning groove 610, which is used to engage with the closed end 310. The end 310 abuts and fits, while the guide frame 700 is provided with a guide channel 710 on the side of the positioning groove 610 facing the insertion port 130. The guide channel 710, the positioning groove 610 and the insertion port 130 are coaxially arranged. The diameter of the guide channel 710 gradually decreases from the insertion port 130 towards the fixing frame 500. The diameter of the guide channel 710 near the insertion port 130 is larger than that near the positioning groove 610, thereby guiding the closed end 310 to fit into the positioning groove 610.

[0050] The sealing component is located between the glass tube 300 and the insertion port 130, and is used to seal and fix the opening end 320 and the insertion port 130.

[0051] During assembly, the closed end 310 of the glass tube 300 is inserted into the water housing 100 through the insertion port 130. Since the diameter of the guide channel 710 gradually decreases from the insertion port 130 towards the fixing frame 500, the closed end 310 of the glass tube 300 can be easily inserted into the guide channel 710 of the guide frame 700. Under the guidance of the guide channel 710, the closed end 310 is quickly and accurately fitted into the positioning groove 610 of the silicone sleeve 600 to achieve elastic fixation of the closed end 310 and to buffer and dampen the glass tube 300. Then, the sealing assembly is used to seal and fix the glass tube 300 and the insertion port 130.

[0052] This utility model guides the installation of the glass tube 300 through the guide channel 710 in the guide frame 700, and at the same time, it has a reinforcing effect, which can effectively prevent the glass tube 300 from tilting and shaking during installation and transportation.

[0053] Among them, such as Figures 1 to 3 As shown, the water shell 100 of this embodiment includes a hollow tube 140, a first end cap 150 and a second end cap 160 respectively sealed and fitted to both ends of the tube 140. In this embodiment, the tube 140 extends in the left-right direction. In other embodiments, the tube 140 may extend in other directions or have an irregular structure. The first end cap 150 and the second end cap 160 are respectively disposed at the left and right ends of the tube 140.

[0054] In this embodiment, the insertion port 130 is located on the first end cap 150, the outlet 120 is located on the second end cap 160, and the inlet 110 is located on the outer peripheral wall of the pipe body 140 near the first end cap 150. Water flows from left to right along the pipe body 140.

[0055] like Figure 4 As shown, the fixing frame 500 is provided with a plurality of water passage holes 510 distributed circumferentially. The plurality of water passage holes 510 connect the water inlet 110 and the water outlet 120. The water outlet 120 and the plurality of water passage holes 510 are offset in the axial direction, so as to prevent ultraviolet light from being emitted from the water outlet 120.

[0056] like Figures 1 to 3 As shown, the inlet 110 is provided with a connecting pipe head 170, which includes a first straight pipe 171 and a second straight pipe 172 that are perpendicularly connected to each other. The first straight pipe 171 is connected to the inlet 110, and the second straight pipe 172 extends along the axial direction of the pipe body 140. The opening of the second straight pipe 172 faces the side of the insertion port 130, which can prevent ultraviolet light from being emitted out of the inlet 110.

[0057] In this embodiment, the outer peripheral wall of the tube 140 is fitted with at least two support frames 180 to achieve the installation and fixation of the entire machine.

[0058] In this embodiment, the second end cap 160 is provided with a mounting groove 161 on the side facing the first end cap 150, and the fixing bracket 500 of this embodiment is fitted into the mounting groove 161.

[0059] like Figure 4 As shown, in this embodiment, the fixing bracket 500 has a mounting groove 520 at the center of the side facing the insertion port 130. The silicone sleeve 600 is installed in the mounting groove 520. The guide bracket 700 has a connecting ring 720 fixed between the outer periphery of the mounting groove 520 and the water shell 100. Specifically, in this embodiment, the connecting ring 720 is fitted inside the side of the second end cover 160 facing the first end cover 150.

[0060] During assembly, the silicone sleeve 600 is installed in the mounting groove 520, the fixing bracket 500 is fitted into the mounting recess 161, the sleeve ring 720 is fitted into the second end cap 160, and then the second end cap 160 is fitted into the right end of the tube body 140.

[0061] like Figure 4 As shown, in this embodiment, the end of the socket 720 facing the insertion port 130 has a plurality of guide blocks 730 distributed circumferentially. The plurality of guide blocks 730 have an inclined guide slope 731 on the side near the axis of the socket 720. The plurality of guide slopes 731 form a guide channel 710, which reduces material usage and lowers manufacturing costs.

[0062] Furthermore, such as Figure 4 As shown, a guide sleeve 740 is provided between multiple guide blocks 730. The inner peripheral wall of the guide sleeve 740 is a tapered surface structure 741 that smoothly transitions and connects with the guide inclined surface 731. The outer diameter of the guide sleeve 740 is smaller than the outer diameter of the sleeve ring 720. The guide sleeve 740 and the sleeve ring 720 are coaxially arranged and are staggered in the axial direction. The guide sleeve 740 is located on the side of the sleeve ring 720 near the insertion port 130.

[0063] In some other embodiments, the inner diameter of the guide sleeve 740 is the same as the outer diameter of the glass tube 300, which has a certain limiting effect on the glass tube 300.

[0064] like Figure 4 As shown, in this embodiment, the inner peripheral wall of the positioning groove 610 is provided with a plurality of positioning protrusions 611 distributed at intervals along the circumference. The positioning protrusions 611 extend along the axial direction of the positioning groove 610. The end of the positioning protrusion 611 near the insertion port 130 is inclined so that the diameter of the groove opening of the positioning groove 610 gradually decreases from the insertion port 130 toward the fixing frame 500, so as to facilitate the insertion of the glass tube 300 and at the same time, to clamp the glass tube 300.

[0065] In this embodiment, the outer periphery of the silicone sleeve 600 is provided with a snap-fit ​​groove 620 that engages with the groove of the mounting groove 520 to improve the firmness of the silicone sleeve 600 installation.

[0066] like Figure 3 As shown, the sealing assembly of this embodiment includes a fixing sleeve 800 and a sealing ring 900. The open end 320 is provided with a skirt 321 extending in all directions. The fixing sleeve 800 is threaded onto the outer periphery of the insertion port 130. The inner peripheral wall of the fixing sleeve 800 is provided with an abutment step 810. The skirt 321 is clamped between the abutment step 810 and the end face of the insertion port 130 to fix the glass tube 300 axially. The sealing ring 900 is provided between the open end 320 and the insertion port 130 to achieve a sealed installation of the glass tube 300.
