Description

Technical Field

[0001] This utility model relates to the field of ozone generator technology, and in particular to a desktop ozone generator. Background Technology

[0002] An ozone generator is a device that converts oxygen (O2) into ozone (O3) using specific technology. It is widely used in water treatment, air disinfection, food processing, medical sterilization, and industrial oxidation. Due to its strong oxidizing properties, ozone can effectively kill bacteria and viruses and decompose organic pollutants without leaving any residue after decomposition, making it an environmentally friendly disinfectant.

[0003] When industrial desktop ozone generators are used, a corona electric field is created in the discharge tube using high-frequency or medium-frequency high-voltage current. This causes oxygen molecules (O2) to undergo an electrochemical reaction in the electric field, decomposing and recombining into ozone (O3).

[0004] In existing technologies, the electrodes on the discharge tube are usually parallel electrodes, which limits the length of the discharge area on the discharge tube and results in a weak electric field. In addition, the inner wall of the discharge tube is usually smooth, and the airflow is quickly discharged after flowing through the discharge tube, resulting in low energy efficiency of the ozone generator. Therefore, we urgently need a desktop ozone generator to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems of limited discharge area length, weak electric field and low energy efficiency of ozone generators in the use of parallel electrodes in the prior art, and to propose a benchtop ozone generator.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A desktop ozone generator includes an ozone generating device and a discharge tube installed in the ozone generating device. The discharge tube mainly consists of a shell, an air inlet, and an air outlet, which are respectively connected to the ozone generating device. It also includes: a spiral high-voltage electrode wound around the outer wall of the shell; several protrusions arranged equidistantly and linearly on the inner wall of the shell (first type); several protrusions arranged equidistantly and linearly on the inner wall of the shell (second type); a rotating shaft rotatably connected to each of the protrusions (second type); a baffle plate fixedly installed on the rotating shaft; a circular through hole on the baffle plate; and a titanium alloy grounding electrode coated on the inner wall of the shell.

[0008] To enhance the electric field, preferably, the spiral high-voltage electrode is wound around the outer wall of the housing with a constant pitch.

[0009] In order to form a vortex, preferably, the height of the first protrusion is in a ratio of 1:20 to the radius of the shell. When the gas passes around the first protrusion, a local double-row vortex will be formed inside the shell.

[0010] To prolong the time the airflow spends in the casing, preferably, the number of the baffles is at least two sets, arranged in a ring at equal intervals on the rotating shaft.

[0011] In order to form a reflux zone, preferably, the circular through hole accounts for 40% of the total area of ​​the baffle. When the gas rotates with the baffle, the shaft rotates and drives the baffle to form a reflux zone in the housing.

[0012] To improve efficiency, preferably, the titanium alloy grounding electrode is made of nano-sized titanium alloy with a coating thickness of 10-50 μm.

[0013] To improve ionization efficiency, the shell material is preferably quartz glass.

[0014] Compared with the prior art, this utility model provides a tabletop ozone generator with the following beneficial effects:

[0015] 1. This desktop ozone generator features a spiral high-voltage electrode wound around the outer wall of the casing. Compared to traditional parallel electrodes, the spiral high-voltage electrode can increase the length of the discharge area by 3-5 times, and the spiral curvature can generate a local electric field enhancement effect. The heat dissipation module is equipped with both water cooling and air cooling. The spiral gap of the high-voltage electrode can be used as a heat dissipation duct, which effectively improves the heat dissipation efficiency and enhances the electric field in the discharge tube, further enhancing the energy efficiency of the ozone generator.

[0016] 2. This desktop ozone generator, through the design of protrusion one and protrusion two, ensures that when the airflow is small, the shaft will not rotate rapidly. The airflow contacts the baffle and is discharged through the circular through-hole, creating a sudden expansion and contraction effect and forming a backflow zone around it. When the airflow is large, the shaft rotates rapidly, forming a local vortex inside the shell, thereby reducing the flow speed of the airflow inside the shell and effectively improving the utilization rate of oxygen.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention improves the energy efficiency of the ozone generator, makes its discharge more uniform, and optimizes the airflow in the discharge tube. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying 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.

[0025] Example:

[0026] Reference Figures 1-4 A desktop ozone generator includes an ozone generating device 1. The ozone generating device 1 includes at least one discharge module, a heat dissipation module, an ozone concentration sensor, and a negative pressure protection device. It is worth noting that the ozone generating device 1 is a direct reference to existing technology and will not be elaborated upon here. The discharge tube 2 installed in the ozone generating device 1 mainly consists of a shell, an inlet, and an outlet. Here, the shell is made of quartz glass, which possesses high dielectric strength and insulation stability, as well as high temperature and thermal shock resistance. As a dielectric, the shell can suppress electric arcs and block direct charge migration through a dielectric barrier, forcing the discharge to occur in a micro-stream form. Furthermore, the quartz glass can enhance ionization efficiency. It should be noted that the oxygen vacancy concentration of the quartz glass needs to be controlled at <10¹. 6 / cm³ to prevent leakage current, the air inlet and outlet are respectively connected to the ozone generator 1, and also includes;

[0027] The spiral high-voltage electrode 3 is wound around the outer wall of the shell with a constant pitch. Compared with the traditional parallel electrode, the spiral high-voltage electrode 3 can increase the length of the discharge area by 3-5 times, and the spiral curvature can generate a local electric field enhancement effect. The heat dissipation module has both water cooling and air cooling. The spiral gap of the spiral high-voltage electrode 3 can be used as a heat dissipation channel, which effectively improves the heat dissipation efficiency. The spiral high-voltage electrode 3 is led out to the high-voltage interface terminal of the discharge module through a silver-copper alloy wire. The terminal adopts a ceramic insulating base to avoid rock surface discharge. It effectively enhances the electric field inside the shell, allowing it to better contact the airflow and form ozone.

[0028] The titanium alloy grounding electrode 9 is coated on the inner wall of the housing. The material of the titanium alloy grounding electrode 9 is nano-sized titanium alloy, and the coating thickness is usually 10-50μm. Here, the titanium alloy coating on the inner wall extends to the end of the housing and is connected to the discharge module shell through an elastic metal spring. The discharge module shell is connected to the system ground bus through a copper braided strip, which improves the conductivity and meets the discharge requirements of high current density. Nano-iridium oxide (IrO2, particle size <50nm) particles can also be added to the coating to reduce the electron work function and enhance the discharge efficiency.

[0029] Several protrusions 4 are arranged in a ring at equal intervals and linearly arrayed on the inner wall of the housing. The height of the protrusions 4 is 1:20 of the housing radius. When the gas passes around the protrusions 4, it will form a local double-row linear vortex inside the housing. When the airflow enters the housing through the air inlet, it will contact the surface of the protrusions 4 and form a Karman vortex street phenomenon, thereby increasing the airflow mixing inside the housing and prolonging the time the airflow stays inside the housing, effectively improving the energy efficiency of the ozone generator.

[0030] Several protrusions 5 are arranged in a ring at equal intervals and linearly arrayed on the inner wall of the housing. A rotating shaft 6 is rotatably connected to each protrusion 5. A baffle 7 is fixedly installed on the rotating shaft 6. There are at least two sets of baffles 7 arranged in a ring at equal intervals on the rotating shaft 6. A circular through hole 8 is opened on the baffle 7. The circular through hole 8 occupies 40% of the total area of ​​the baffle 7. When the gas rotates with the baffle 7, the rotating shaft 6 rotates and drives the baffle 7 to form a return flow zone in the housing. Combined with the vortex formed by the protrusions 4, the contact between the airflow and the current is further improved, thereby improving the energy efficiency of the ozone generator.

[0031] Here, the rotating shaft 6 is equipped with damping. When the airflow is small, the rotating shaft 6 will not rotate rapidly. The airflow contacts the baffle 7 and is discharged through the circular through hole 8. The airflow produces a sudden expansion and contraction effect and forms a backflow zone around it. When the airflow is large, the rotating shaft 6 rotates rapidly and forms a local vortex in the shell, thereby reducing the flow speed of the airflow in the shell and effectively improving the utilization rate of oxygen.

[0032] In this invention, the operator starts the ozone generator and uses an external air pump to discharge oxygen into the discharge tube 2 through the air inlet. The discharge module is activated, and the high-voltage electric field generated by the spiral high-voltage electrode 3 excites oxygen molecules. When the airflow passes through the first protrusion 4, a certain amount of backflow is formed. Combined with the design of the baffle 7 and the circular through hole 8 on the second protrusion 5, the running speed of the airflow in the discharge tube 2 is effectively slowed down, thereby improving the utilization rate of oxygen. The airflow is discharged through the air outlet on the discharge tube 2, completing the generation of ozone.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
