Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, and in particular to a flow-through disinfection module. Background Art

[0002] In the water purification equipment market, more and more ultraviolet sterilization modules are being installed in water purification equipment. For example, patent CN220116269U discloses a flow-through ultraviolet sterilization module, the inner surface of which has a structure for achieving diffuse reflection, and a through hole corresponding to the position of the germicidal lamp is provided on the reflective film, so that the light of the germicidal lamp can fully irradiate the reflective film, and always maintain high-intensity irradiation of the water flow in the light-transmitting tube; when the germicidal lamp irradiates, the reflective film diffusely reflects the light of the germicidal lamp, so that the light of the germicidal lamp can irradiate and sterilize the water flow in the light-transmitting tube from multiple angles.

[0003] However, existing over-flow sterilization modules usually achieve the purpose of heat dissipation directly through flowing water. But in the absence of water, the UV LED (ultraviolet light) light source still works normally, which causes the light source to be unable to dissipate heat in time, thus affecting its lifespan. In more serious cases, the entire product will be burned.

[0004] In addition, the pressure of municipal water cannot be controlled, which will result in the sterilization effect not being met when the pressure is too high and the water flow is too fast; and when the pressure is too low and the water flow is slow, the life of the light source will be excessively consumed, thereby reducing the life of the entire product and increasing power consumption. Utility Model Content

[0005] The purpose of the utility model is to overcome the above-mentioned technical deficiencies and propose an over-flow disinfection module to solve the technical problem that the over-flow disinfection module in the prior art cannot take into account both the ultraviolet sterilization effect and the extension of the service life of the module.

[0020] In some embodiments, the accommodating cavity is provided with a first section and a second section along a direction away from the partition, the inner diameter of the first section is larger than the inner diameter of the second section, so as to form a step surface between the first section and the second section, and the internal thread is formed on the inner side wall of the first section;

[0021] The transparent plate is placed between the pressing cylinder and the step surface, and the ultraviolet luminous plate is placed in the second section.

[0022] In some embodiments, the flow sensor includes a water flow rotor and a Hall switch. The water flow rotor is disposed in the inner cavity and can be driven by the fluid to rotate and generate pulses.

[0035] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] In order to solve the technical problem that the flow-through disinfection module in the prior art cannot take into account both the ultraviolet sterilization effect and the extension of the service life of the module, the utility model provides an flow-through disinfection module that can take into account both the sterilization effect and the extension of the service life of the module.

[0037] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 It is a structural schematic diagram of an over-flow disinfection module in an embodiment of the utility model, wherein the over-flow disinfection module comprises an outer shell 1, a partition 2, a cylinder 3, a flow sensor 4 and an ultraviolet unit 5; the partition 2 is arranged in the inner cavity of the outer shell 1, and divides the inner cavity into two cavities 1a, and the inner wall of each cavity 1a is provided with a liquid port 1b; the cylinder 3 is penetrated by the partition 2 to connect the two cavities 1a, and a connecting port 3a is provided at one end of its side wall; the flow sensor 4 is arranged in the inner cavity for monitoring the liquid flow; the ultraviolet unit 5 is blocked at one end of the cylinder 3 close to the connecting port 3a, and can emit ultraviolet rays toward the cylinder 3, and is electrically connected to the flow sensor 4, and its working power is positively correlated with the monitoring data of the flow sensor 4.

[0038] In the flow-through disinfection module provided by the utility model, water flows from the corresponding liquid-through port 1b into the cavity 1a containing the ultraviolet unit 5, and then flows into the cylinder 3 through the connecting port 3a. At this time, the flow direction of the water is bent, which increases the flow stroke of the water in the inner cavity, prolongs the irradiation time of the ultraviolet unit 5 on the water, and thus improves the water disinfection ability. At the same time, the water flow in the inner cavity is monitored in real time by means of the flow sensor 4, and the working power of the ultraviolet unit 5 is adjusted according to the water flow. When the fluid stops flowing, the flow sensor 4 monitors the water flow as zero, and the monitoring data is fed back to the ultraviolet unit 5, so that the ultraviolet unit 5 stops working synchronously, avoiding the ultraviolet unit 5 from working for a long time without heat dissipation and reducing the service life of the product; and the flow sensor 4 feeds back electrical signals of different intensities by monitoring the height of the water flow, so that the ultraviolet unit 5 is adjusted to the corresponding sterilization power. The smaller the flow rate, the smaller the power of the given ultraviolet unit 5; the larger the flow rate, the greater the power of the given ultraviolet unit 5, which improves the utilization rate of the product, also achieves the effect of energy saving, and prolongs the service life of the module.

[0039] In one embodiment, see Figure 3 The over-flow disinfection module also includes a reflective tube 6, which is located in the cavity 1a away from the connecting port 3a, and is sleeved outside the cylinder 3, and a reflective layer is provided on its inner wall surface.

[0040] In this embodiment, a reflective layer is provided on the inner wall of the reflective tube 6 to improve its reflectivity to ultraviolet rays, greatly increasing the ultraviolet intensity in the sterilization cavity 1a, thereby improving the sterilization rate. It should be noted that in this solution, the reflective tube 6 is made of polytetrafluoroethylene (PTFE), which has a relatively high reflectivity to ultraviolet rays.

[0041] In one embodiment, see Figure 4 The liquid port 1b located on the same side of the partition 2 as the ultraviolet unit 5 is the inlet 1c, and the other liquid port 1b is the outlet 1d; the flow-through disinfection module also includes a porous plate 7, which is located on the side of the reflective cylinder 6 away from the partition 2 and is provided with a plurality of through holes, each of which connects the outlet 1d and the reflective cylinder 6.

[0042] In this embodiment, a porous plate 7 is arranged at the position of the liquid flow. The porous plate 7 can play a filtering role on the one hand, and on the other hand, the porous plate 7 is also made of polytetrafluoroethylene (PTFE) material to further improve the ultraviolet intensity in the sterilization chamber, thereby improving the sterilization effect. It should be noted that in this solution, a sealing ring 10 is arranged between the porous plate 7 and the inner wall of the cavity 1a, and a sealing ring 10 is also arranged between the reflective cylinder 6 and the cylinder 3. The material of the sealing ring 10 is ethylene propylene diene monomer (EPDM). The porous plate 7 has eight through holes, and the diameter of each through hole is 4 mm.

[0043] In one embodiment, see Figure 5 There are multiple communication ports 3a, and the multiple communication ports 3a are arranged at intervals along the circumferential direction of the cylinder 3.

[0044] In this embodiment, multiple communication ports 3a are arranged at intervals on the circumference of the cylinder 3 to improve the water purification efficiency of the module. It should be noted that in this solution, the cylinder 3 is made of polytetrafluoroethylene (PTFE) to improve the reflection ability of ultraviolet rays therein. There are six communication ports 3a, each of which is a rectangular notch of 3 mm x 4 mm.

[0045] In one embodiment, see Figure 6 and Figure 7 The ultraviolet unit 5 includes a lamp board base 51, an ultraviolet light-emitting plate 52 and a transparent plate 53. The lamp board base 51 is installed in the corresponding cavity 1a and is provided with a receiving cavity 51a with an opening toward the partition 2. The ultraviolet light-emitting plate 52 is arranged in the receiving cavity 51a and can emit ultraviolet rays toward the cylinder 3. The transparent plate 53 is pressed against the side of the ultraviolet light-emitting plate 52 close to the partition 2.

[0046] In this embodiment, the ultraviolet luminous plate 52 is isolated in the accommodating cavity 51a of the lamp plate base 51 by the transparent plate 53 to prevent the fluid from infiltrating the ultraviolet luminous plate 52 and extend the service life of the ultraviolet luminous plate 52. It should be understood that the ultraviolet luminous plate 52 includes a circuit board and a plurality of lamp beads, and the plurality of lamp beads are arranged on one side of the circuit board close to the partition 2. In addition, it should be noted that in this solution, the transparent plate 53 is made of optical quartz glass.

[0047] Specifically, the lamp board base 51 is made of 304 stainless steel, and a circuit board (PCB board) is arranged on the lamp board base 51, which is made of aluminum alloy. A plurality of UV LED lamp beads are arranged on the PCB board, which are distributed in a symmetrical array. The PCB board is provided with quartz glass, and the material of the quartz glass is high-purity silica refined from synthetic raw materials. This synthetic raw material is melted by electric melting or hydrogen-free flame to form optical quartz glass, which can well transmit the continuous spectrum from far ultraviolet to near infrared, and the transmittance at an ultraviolet wavelength of 275nm can reach 92%.

[0048] In one embodiment, the inner wall of the open end of the accommodating cavity 51a is provided with an internal thread, and the ultraviolet unit 5 also includes a pressing tube 54, the outer wall of the pressing tube 54 is provided with an external thread so that it can be screwed into the lamp board base 51; the transparent plate 53 is placed between the pressing tube 54 and the ultraviolet light-emitting board 52.

[0049] In this embodiment, the transparent plate 53 is stably pressed against the ultraviolet light emitting plate 52 by the pressing tube 54, which limits the accidental movement of the pressing tube 54, ensures that the transparent plate 53 effectively isolates the solution, and is easy to disassemble and assemble, thereby improving the convenience of assembly and maintenance.

[0050] In one embodiment, the accommodating cavity 51a is provided with a first section 511 and a second section 512 along a direction away from the partition 2, the inner diameter of the first section 511 is larger than the inner diameter of the second section 512, so as to form a step surface 513 between the first section 511 and the second section 512, and an internal thread is formed on the inner side wall of the first section 511; the transparent plate 53 is placed between the pressing cylinder 54 and the step surface 513, and the ultraviolet light-emitting plate 52 is placed in the second section 512.

[0051] In this embodiment, the transparent plate 53 is pressed between the pressing tube 54 and the step surface 513 to prevent the transparent plate 53 from directly contacting the ultraviolet light emitting plate 52 and damaging the ultraviolet light emitting plate 52, so that the ultraviolet light emitting plate 52 is not easily damaged, thereby extending the service life of the module.

[0052] In one embodiment, the flow sensor 4 includes a water flow rotor 41 and a Hall switch 42. The water flow rotor 41 is arranged in the inner cavity and can be driven by the fluid to rotate and generate pulses. The Hall switch 42 is electrically connected to the ultraviolet unit 5 to monitor and receive the pulse signal of the water flow rotor 41 and feedback to generate an electrical signal. In addition, it should be noted that in this solution, the over-flow disinfection module also includes a control system 9, which is electrically connected to the Hall switch 42 and the ultraviolet light-emitting plate 52 respectively.

[0053] In this embodiment, when the fluid enters the cavity 1a through the inlet 1c, the fluid drives the water flow rotor 41 to rotate, and the water flow rotor 41 generates pulses after rotation. The Hall switch 42 feeds back an electrical signal through the monitored pulse signal, and the control system 9 controls the ultraviolet light-emitting plate 52 to start working after receiving the electrical signal. When the fluid stops flowing, the water flow rotor 41 stops rotating, the Hall switch 42 cannot detect the pulse signal, and cannot transmit the electrical signal to the control system 9, and the ultraviolet light-emitting plate 52 stops working. This method can prevent the ultraviolet light-emitting plate 52 from working for a long time without heat dissipation, thereby reducing the service life of the product.

[0054] In the present applicable new solution, the flow sensor 4 can also feedback electrical signals of different intensities by monitoring the height of the pulse signal. The control system 9 determines the size of the flow rate and gives the corresponding sterilization power to the ultraviolet light-emitting plate 52. The smaller the flow rate, the smaller the power of the given ultraviolet light-emitting plate 52. The larger the flow rate, the greater the power of the given ultraviolet light-emitting plate 52. This method greatly improves the utilization rate of the product and also achieves the effect of energy saving.

[0055] In one of the embodiments, the flow-through disinfection module also includes a display panel 8, which is disposed on the outer wall of the housing 1 and is electrically connected to the flow sensor 4 and the ultraviolet unit 5, respectively, for displaying the working parameters of the flow sensor 4 and the ultraviolet unit 5.

[0056] In this solution, an LCD display panel 8 is provided outside the product, which can clearly display the working status of each component of the product, making it more convenient to use. This not only reduces the maintenance cost of the product, but also facilitates timely replacement of the product when a failure occurs.

[0057] In one embodiment, the housing 1 includes a first outer cylinder 11 and a second outer cylinder 12 , wherein the first outer cylinder 11 is screwed to the second outer cylinder 12 to form an inner cavity together with the second outer cylinder 12 , wherein the partition 2 is disposed in the first outer cylinder 11 .

[0058] In this way, when the housing 1 device needs to be repaired or replaced, it is only necessary to drive the first outer cylinder 11 and the second outer cylinder 12 to rotate relative to each other. The disassembly and assembly operation is simple and convenient, and the structure is simple and cost-saving. It should be noted that in this embodiment, the housing 1 is made of 304 stainless steel. The first outer cylinder 11 and the second outer cylinder 12 are respectively provided with G1 / 2 standard thread patterns.

[0059] In order to better understand the present invention, the following Figures 1 to 7 The technical solution of the utility model is described in detail:

[0060] After water flows into the corresponding cavity 1a from the inlet 1c, it flows into the cylinder 3 through the connecting port 3a. At this time, the flow direction of the water is bent, which increases the flow distance of the water in the inner cavity and prolongs the irradiation time of the ultraviolet unit 5 on the water, thereby improving the water disinfection ability.

[0061] When the fluid enters the inner cavity through the inlet 1c, the fluid will drive the water flow rotor 41 to rotate. After the water flow rotor 41 rotates, pulses will be generated. The Hall switch 42 feeds back an electrical signal through the monitored pulse signal. After receiving the electrical signal, the control system 9 controls the ultraviolet light-emitting plate 52 to start working. When the fluid stops flowing, the water flow rotor 41 stops rotating, the Hall switch 42 cannot detect the pulse signal and cannot transmit the electrical signal to the control system 9, and the ultraviolet light-emitting plate 52 stops working. This method can prevent the ultraviolet light-emitting plate 52 from working for a long time without heat dissipation, thereby extending the service life of the product.

[0062] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
