Abstract
Description
Technical Field
[0001] This invention belongs to the field of water purification technology, and particularly relates to a central tube structure for a water purification device. Background Technology
[0002] In the process of water purification using spiral reverse osmosis membranes, raw water is filtered through the reverse osmosis membrane and gradually converges into the central tube to produce pure water. Over long-term use, bacteria can easily grow on the inner wall of the central tube, causing water pollution. This requires regular cleaning of the central tube. The inner wall of the central tube is relatively closed, making frequent cleaning inconvenient. On the other hand, water purifiers often include an additional heating device after purification, which occupies a certain amount of space. Therefore, a central tube that can solve the above problems is needed.

By using a rectifier device in conjunction with the UV disinfection lamp, the water flow is rectified after passing through the rectifying orifices of the rectifier device, effectively reducing turbulence or eddies. Combined with UV disinfection, this achieves better purification and disinfection results.

[0033] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.
[0034] like Figures 1 to 14 As shown, a central pipe structure for a water purification device includes a central pipe 1, a disinfection device 2, a heating structure, and a flow channel baffle structure. The disinfection device 2 and the heating structure are disposed within the central pipe 1. The heating structure includes heating structure A and heating structure B7. The flow channel baffle structure is disposed on the heating structure and includes flow channel baffle structure A and flow channel baffle structure B6. The flow channel baffle structure forms a certain water flow channel in the space between the outer wall of the heating pipe 3 and the inner wall of the central pipe 1.
[0035] The central tube 1 has an annular columnar structure, with one end closed and the other end open. The central tube 1 is provided with several water collection holes 101, cavity structures 102, and protrusions 103. The cavity structures 102 are arranged in a cross pattern, and the disinfection device 2 is disposed within each cavity structure 102. Generally, the divergence angle of an ultraviolet light-emitting tube is approximately 120°. To ensure uniform emission intensity in all directions, multiple cavity structures 102 are provided, with four cavity structures 102 evenly arranged around the inner circumference of the central tube 1. A water collection hole 101 is provided between each cavity structure 102, allowing water to flow into the central tube 1 from the water collection hole 101.
[0036] The disinfection device 2 has an ultraviolet emission function. The disinfection device 2 includes a long strip circuit board 201, a light-emitting chip 202, circuit wires 203, electrodes 204, and electrode leads 205. The light-emitting chip 202 is mounted on the circuit board 201 and is connected to the electrodes 204 via the circuit wires 203. The electrodes 204 are connected to the electrode leads 205 of the disinfection device, which extend from one end of the central tube 1. The circuit board 201 is a PCB circuit board.
[0037] The heating structure A includes a heating tube 3 and a heating element A5. The heating tube 3 is a heating carrier located in the inner wall space of the central tube 1. The heating element A5 is a resistance heating heat source, and the heating method can be resistance wire heating. The heating element A5 includes a heating wire heat source 501 and a heating wire electrode lead 502. The heating wire heat source 501 is disposed inside the heating tube 3. The heating tube 3 is made of calcium oxide ceramic and zirconium oxide ceramic, which have high thermal conductivity and insulation characteristics. The flow channel partition structure is disposed on the heating tube 3. The resistance wire of the heating element A5 is encapsulated inside the heating tube. The heating wire electrode lead 502 is led out from one end of the heating tube 3.
[0038] One end of the heating element 3 is the bottom 301, which is connected to the flow channel baffle structure. The other end of the heating element 3 is the outlet end 302, where pure water flows out. A connection 303 is provided on the heating element 3.

It flows to the bottom 301 of the heating tube in the flow channel formed by the spiral baffle 4, and then flows out of the central tube 1 from the inner wall of the heating tube 3 towards the outlet end 302 of the heating tube.
[0039] The heating structure B7 includes a heating tube 3 and a heating element B701. A conductive layer 702 and an insulating layer 704 are disposed on the heating tube 3.

[0041] The flow channel baffle structure B6 includes flow channel baffles 4 and a sealing element 603. The flow channel baffles 4 are arranged in parallel directions to form a double spiral channel, so as to increase the length of the spiral flow channel of the flow channel baffles 4 and the heated surface area of the water body, and ensure that the inner wall of the central tube 1 can be disinfected by ultraviolet light. The two flow channel baffles 4 form an inlet spiral flow channel 601 and an outlet spiral flow channel 602 on the flow channel baffle structure B6. The outlet end of the inlet spiral flow channel 601 is sealed by the sealing element 603 on the central tube 1. One end of the inlet spiral flow channel 601 and the outlet spiral flow channel 602 are connected at the double spiral flow channel connection 604 at the bottom of the heating tube 3 of the heating structure. The other end of the inlet spiral flow channel 601 is connected to the water collection hole 101. The water flows out of the central tube 1 through the flow channel outlet 605 of the outlet spiral flow channel 602.
[0042] The light-emitting chip 202 is an LED light-emitting chip, using ultraviolet semiconductor InGaN / AlGaN and MgZnO / ZnO heterojunction and quantum well light-emitting diode as light source. Several light-emitting chips 202 are connected in parallel on the circuit board 201 to ensure ultraviolet light illumination.
