Description

Technical Field

[0001] The utility model relates to the technical field of ozone generators, and more specifically, to an ozone tube module with temperature detection. Background Art

[0002] As people's living standards are getting better and better, consumers' requirements for faucets used in daily life are getting higher and more diversified. Electronic smart sensor faucets have also gradually entered our daily lives, but some electronic sensor faucets can only sense water out or water off, and have no sterilization function. Long-term use will gradually increase the amount of impurities remaining in the water pipes, and the microorganisms in the water will accumulate more and more, and the water quality will gradually deteriorate. When drinking or washing vegetables and fruits, various bacteria and microorganisms that are not good for the human body will enter the human body, destroying the balance of bacterial species in the human body, and in severe cases will affect physical health. Currently, the faucets with sterilization function on the market include ozone sterilization faucets, ultraviolet sterilization faucets, etc. Among them, the sterilization effect of ozone faucets is relatively ideal, but the cost of ozone tubes is relatively high, and they will release heat when working, which will increase the temperature of the ozone tubes. If the ozone tubes work at high temperature for a long time, the service life will be seriously reduced. For example, a faucet with ozone sterilization function disclosed in the patent with authorization announcement number CN206130236U has an ozone generator on the water outlet elbow, so that the water flowing out of the faucet has the effect of disinfection and sterilization, but the ozone generator is easy to generate heat, and too high temperature will reduce the output of ozone gas. In addition, the ozone tube works at high temperature for a long time, which is easy to cause problems such as short life and inconvenient maintenance. Utility Model Content

[0031] like Figures 1 to 6 As shown, the utility model provides an ozone tube module with temperature detection, comprising:

[0032] The housing 100 has a rectangular cavity on its top surface, and both ends of the housing 100 have through holes connected to the cavity;

[0033] An ozone tube electrode is installed in the cavity, and includes an inner electrode 200, a glass tube 201, an outer electrode 202 and a heat shrink tube 203 which are coaxially sleeved from the inside to the outside. A temperature sensor 204 is installed between the outer electrode 202 and the heat shrink tube 203. The inner electrode 200 and the outer electrode 202 are electrically connected to the ozone generator through two connecting wires 205, respectively. The temperature sensor 204 is also electrically connected to the ozone generator.

[0034] The two ends of the ozone tube electrode are respectively connected to an air inlet pipe 300 and an air outlet pipe 301 , and the air inlet pipe 300 and the air outlet pipe 301 pass through the through holes at the two ends of the shell 100 .

[0035] The ozone tube module with temperature detection provided in the technical solution is composed of a shell 100 and an ozone tube electrode. The shell 100 is provided with a cavity for accommodating the ozone tube electrode, and both ends of the shell 100 are provided with through holes connected to the cavity. The ozone tube electrode is cylindrical, including an inner electrode 200, a glass tube 201 is sleeved on the outer periphery of the inner electrode 200, an outer electrode 202 is sleeved on the outer periphery of the glass tube 201, a temperature sensor 204 is installed in the middle of the surface of the outer electrode 202, and then a circle of thermoplastic sleeve is wrapped around the outer periphery of the outer electrode 202. After the thermoplastic sleeve is heated and shrunk by hot air, the temperature sensor 204 can be in close contact with the outer electrode 202, so as to better monitor the temperature of the surface of the outer electrode 202. The end of the inner electrode 200 and the surface of the outer electrode 202 are respectively connected to two connecting wires extending outward by welding, and the two connecting wires are respectively connected to the ozone generator (not shown in the figure). The temperature sensor 204 is also electrically connected to the control circuit of the ozone generator (not shown in the figure). The ozone tube electrode is controlled by the ozone generator to produce ozone. In addition, the two ends of the inner electrode 200 are respectively connected to the air inlet pipe 300 and the air outlet pipe 301, and the air inlet pipe 300 and the air outlet pipe 301 are respectively passed through the through holes at the two ends of the shell 100. When in use, air enters the inner electrode 200 from the air inlet pipe 300. When the ozone generator is working, high frequency and high voltage are applied to the two connecting wires electrically connected to the inner and outer electrodes. The high frequency and high voltage will arc discharge between the two electrodes, ionize the air inside the inner electrode 200, decompose the oxygen molecules in the air into oxygen atoms, and the oxygen atoms are recombined with the oxygen molecules to generate ozone molecules, that is, generate ozone gas, and then the ozone gas is output through the air outlet pipe 301, thereby obtaining ozone gas. The ozone tube electrode will generate heat during the process of generating ozone, and too high a temperature will reduce the ozone gas production and also affect the life of the ozone tube. Therefore, the present invention adds a temperature sensor 204 to detect the surface temperature of the outer electrode 202 in real time. Preferably, when the surface temperature of the outer electrode 202 exceeds 80°C, the ozone generator will automatically shut down, which can effectively extend the life of the ozone tube.

[0036] In another technical solution, the inner electrode 200 is provided with an airflow portion 210 in the middle portion along the axial direction, and connecting portions 211 are provided at both ends. Both ends of the airflow portion 210 are provided with annular convex edges 212 extending outwardly perpendicular to the curved side walls of the airflow portion 210, and the curved side walls of the annular convex edges 212 are provided with sealing ring grooves 213 recessed inwardly along the circumferential direction. The outer end of each connecting portion 211 is provided with an air vent 214 extending inwardly along the axis. The airflow portion 210 is provided with an air guide hole 1 215 and an air guide hole 216 extending in the radial direction. The air guide hole 1 215 and the air guide hole 216 are respectively close to the two annular convex edges 212 and are respectively connected to the adjacent air vents 214. The air inlet pipe 300 and the air outlet pipe 301 are respectively sleeved on the outside of the two connecting portions 211 and are respectively connected to the corresponding air vents 214. In the technical solution, the inner electrode 200 is divided into a middle airflow portion 210 and two end connection portions 211. The airflow portion 210 is provided with a narrow position for reserving airflow, which is used to form an airflow cavity with the inner circle of the glass tube 201. The airflow cavity is also a discharge cavity. When in use, air enters the airflow cavity from the air inlet pipe 300 through the air guide hole 1 215. When the ozone tube is working, high frequency and high voltage are applied to the two electrodes. The high frequency and high voltage will arc discharge between the two electrodes to ionize the air inside the airflow cavity, so that the oxygen molecules in the air in the airflow cavity are decomposed into oxygen atoms, and the oxygen atoms are recombined with the oxygen molecules to generate ozone molecules, that is, ozone gas is generated in the airflow cavity, and then the ozone gas is output from the air outlet pipe 301 through the air guide hole 216, so as to achieve the purpose of obtaining ozone.

[0037] In another technical solution, the length of the glass tube 201 is consistent with the length of the airflow portion 210, the inner diameter of the glass tube 201 is consistent with the outer diameter of the annular convex edge 212, a sealing ring 217 is arranged in the sealing ring groove 213, the glass tube 201 is sealingly sleeved on the outer periphery of the airflow portion 210, and an annular airflow cavity 218 is formed between the middle part of the airflow portion 210 and the glass tube 201, the airflow cavity 218 is connected with the air guide hole 1 215 and the air guide hole 216, and the axial directions of the air guide hole 1 215 and the air guide hole 216 are perpendicular to each other. In the present technical solution, the glass tube 201 is made of a quartz glass tube, which is hollow inside, allowing the inner electrode 200 to pass through the hollow part of the glass tube 201. Sealing rings 217 are sleeved at both ends of the airflow portion 210 of the inner electrode 200, and the glass tube 201 is tightly sleeved on the outer periphery, which effectively prevents the ozone in the airflow cavity 218 from leaking out. The air guide hole 1 215 and the air guide hole 216 are arranged at perpendicular angles to each other to avoid the airflow from flowing in a straight line, so that the airflow can discharge in the airflow cavity 218 over as large an area as possible to generate ozone, thereby improving the ozone generation efficiency.

[0038] In another technical solution, the air inlet pipe 300 and the air outlet pipe 301 are both silicone tubes made of ozone-resistant material, and the curved side walls of the two connecting parts 211 are both provided with inwardly recessed card grooves 219 along the circumferential direction. In this technical solution, the inner electrode 200 is made of stainless steel material, and the radius of the connecting parts 211 provided at both ends thereof is smaller than the radius of the air flow part 210. The air inlet pipe 300 and the air outlet pipe 301 are both silicone tubes, and the two are tightly sleeved on the outer periphery of the card grooves 219 on the two connecting parts 211 to ensure air tightness.

[0039] In another technical solution, the outer electrode 202 is a tubular structure made of copper foil, and its length is the same as the distance between the first air guide hole 215 and the second air guide hole 216 .

[0040] In another technical solution, the inner electrode 200 is made of stainless steel. In this technical solution, stainless steel is used to make the inner electrode 200 conductive and ozone resistant.

[0041] In another technical solution, the temperature sensor 204 is an NTC temperature sensor, which is disposed in the middle of the outer wall of the outer electrode 202 and is wrapped around the outer periphery of the outer electrode 202 by the heat shrink tubing 203 for heat shrinkage fixation. In this technical solution, the heat shrink tubing 203 is used to make the NTC temperature sensor in close contact with the copper foil of the outer electrode 202, so that the temperature of the surface of the copper foil of the outer electrode 202 can be better detected.

[0042] In another technical solution, the housing 100 is made of plastic, and the ozone tube electrode is potted in the cavity of the housing 100 by waterproof glue. In this technical solution, waterproof glue is used to achieve waterproof and moisture-proof of the ozone tube module, making it suitable for humid environments such as toilets.

[0043] In another technical solution, the side wall of the housing 100 is provided with a plurality of extensions 101 extending outward, and each extension is provided with a screw hole 102. In this technical solution, the screw holes are provided to facilitate the use of screws to fix the ozone tube module with temperature detection in an appropriate position, thereby improving installation convenience.
