Abstract
Description
Technical Field
[0001] This application relates to the field of ozone water preparation technology, and in particular to an ozone mixing device. Background Technology
[0002] Ozone is a strong oxidant with powerful oxidizing ability, resulting in strong bactericidal and disinfecting effects. Ozone water, produced by dissolving ozone gas in water, also possesses strong oxidizing properties and can be used more conveniently through spraying, soaking, and rinsing. Ozone water can kill bacteria and viruses on object surfaces, remove pesticide residues from fruits and vegetables, and causes no secondary pollution, making it a green and environmentally friendly disinfectant. Because ozone decomposes rapidly after dissolving in water, ozone water is generally prepared and used immediately. It is produced in real-time using an ozone generator to generate gaseous ozone, which is then dissolved in the water flow to form ozone water.
[0003] Outdoor activities are now a popular choice for many, such as hiking, camping, and picnicking. The complex outdoor environment makes disinfection of food and water essential. Additionally, injuries sustained during outdoor activities require prompt disinfection. Ozone water, with its excellent disinfection properties, is an ideal choice. Some existing outdoor ozone sterilizers mainly consist of a high-pressure pump, an ozone generator, an air compressor, and an ejector. Air enters the ozone generator to produce ozone, the air compressor extracts the ozone and discharges it into the ejector, and the high-pressure pump pumps water to mix with the ozone in the ejector to produce ozone water. However, using an ejector as the ozone mixing device results in a large and heavy overall device, increasing portability and leading to high energy consumption and cost, making it difficult to meet the needs of portable outdoor use. Utility Model Content
[0004] To address the inconvenience of obtaining ozone water with a high and stable concentration, this application provides an ozone mixing device.
[0005] The ozone mixing device provided in this application adopts the following technical solution:
[0006] An ozone mixing device includes a housing, a water pump, and an ozone generator. The water pump is provided with a suction pipe and a drain pipe. The ozone generator is provided with an inlet pipe and an outlet channel. The drain pipe is connected to the inlet pipe. A baffle is provided in the outlet channel. The baffle is provided with at least one opening. The area of the lower surface of the opening is smaller than the area of its upper surface.
[0007] By adopting the above technical solution, the water pump pumps water into the system through the suction pipe and delivers it to the inlet pipe through the drain pipe. The ozone generator produces ozone gas by electrolyzing water. The fluid, which is initially mixed with water, enters the outlet pipe through the drain pipe. The baffle is set perpendicular to the water flow direction, and the orifice diameter gradually decreases from top to bottom. The change in orifice diameter causes the fluid to experience a process where the pipe diameter suddenly decreases and then increases. This causes the fluid to generate speed and pressure differences when passing through different positions, forming a vortex effect, which enhances the contact time and mixing uniformity between ozone and water, and promotes the mixing of ozone and water.
[0008] Preferably, the opening is arc-shaped.
[0009] Preferably, there are two openings, and the two openings are arranged symmetrically.
[0010] Preferably, the liquid outlet channel includes a liquid outlet pipe and a water outlet pipe. The liquid outlet pipe is connected to the ozone generator, and the water outlet pipe is installed through the housing. The liquid outlet pipe and the water outlet pipe are connected.
[0011] Preferably, the liquid outlet pipe is inserted into the water outlet pipe, and the liquid outlet pipe and the water outlet pipe are arranged vertically, with water flowing through the lower liquid outlet pipe into the upper water outlet pipe.
[0012] Preferably, at least one baffle is provided in the liquid outlet channel.
[0013] Preferably, it also includes a filter assembly, which contains a filter element. One end of the filter assembly has a water inlet, and the other end of the filter assembly has a water outlet, which is connected to the water suction pipe.
[0014] Preferably, the filtration assembly includes a first filter cylinder and a second filter cylinder coaxially fixedly connected, the inner diameter of the second filter cylinder is smaller than the inner diameter of the first filter cylinder, the first filter cylinder and the second filter cylinder are connected by an annular stepped surface, the water inlet is located on the end face of the first filter cylinder away from the annular stepped surface, and the water outlet is located on the end face of the second filter cylinder away from the annular stepped surface.
[0015] Preferably, a connecting seat is fixed between the filter assembly and the water pump. The connecting seat has a connecting channel. One end of the connecting seat is fixedly connected to the second filter cartridge. The water outlet is connected to the connecting channel. The other end of the connecting seat is fixedly connected to the water suction pipe. The opening of the water suction pipe is connected to the connecting channel.
[0016] Preferably, a water quality detector is fixed on the connector, and one end of the water quality detector extends into the connector channel to detect the water quality of the water flowing out of the outlet.
[0017] Preferably, it also includes a power supply module, which supplies power to the water pump and the ozone generator.
[0018] Preferably, the housing has a plug-in interface for connecting to an external power source.
[0019] Preferably, the openings are arc-shaped and spaced apart.
[0020] Preferably, a sealing element is provided between the connecting seat and the second filter cartridge, the sealing element being used to seal the end face connection between the connecting seat and the second filter cartridge.
[0021] Preferably, the sealing element includes an annular portion and a recessed portion, the second filter cartridge presses the annular portion between the contact surface of the second filter cartridge and the connecting seat, the sidewall of the recessed portion abuts against the pipe wall of the connecting channel, and the bottom of the recessed portion has a through hole.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. Ozone mixes well with water. The aperture of the baffle gradually decreases from top to bottom. The change in flow rate gradient promotes gas-liquid mixing. The change in aperture causes the fluid to form a vortex effect, which enhances the contact time and mixing uniformity of ozone and water.
[0024] 2. The device is smaller and more portable, with low energy consumption and cost. The water pumped in is the liquid that provides the ozone generator for electrolysis and is also the liquid that dissolves ozone. One water pump serves as the power source, saving energy and space. At the same time, baffles and openings are set in the water outlet pipe to help ozone and water mix. The structure is simple and the cost is low. The battery installation eliminates the need for a power outlet, making it convenient for outdoor use.
[0025] 3. The system is equipped with a water pretreatment device and a water quality testing instrument. The equipment has a long service life and is applicable to a wide range of scenarios. It can use either purified water or directly take water from external sources for filtration. The two-stage filtration ensures the cleanliness of the incoming water, reduces the failure rate of the water pump and ozone generator caused by impurities, and prevents impurities from interfering with the ozone dissolution efficiency, thereby improving the reliability of ozone water preparation.

Detailed Implementation
[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0034] This application discloses an ozone mixing device. (Refer to...) Figure 1 and Figure 2 The ozone mixing device includes a housing 1, a filter assembly 2, a connector 3, a water quality analyzer 4, a power supply module 5, a water pump 6, and an ozone generator 7. The connector 3, water quality analyzer 4, power supply module 5, water pump 6, and ozone generator 7 are installed inside the housing 1. The filter assembly 2 is mounted on the housing 1, with one end extending into the housing 1 and connected to the water pump 6 via the connector 3. The filter assembly 2 contains a filter element for pre-filtration of the water entering the water pump 6. A connecting channel 31 runs through the connector 3 to connect the filter assembly 2 and the water pump 6. The water quality analyzer 4 is fixed to the connector 3, with its detection end extending into the middle section of the connecting channel 31 for detecting the quality of the filtered water. The power supply module 5 provides power to the water pump 6 and the ozone generator 7. The tested water flows through the water pump 6 and is pumped into the ozone generator 7. The ozone generator 7 generates ozone gas by electrolyzing water. The ozone gas and water flow out of the ozone generator 7 and mix to form ozone water. The housing 1 is provided with an outlet pipe 11 that is connected to the ozone generator 7. The ozone water is pumped out from the outlet pipe 11.
[0035] Reference Figure 3 and Figure 4The filter assembly 2 has an inlet hole 21 at one end facing the outside, and an outlet hole 22 at the end extending into the housing 1. The water pump 6 has a suction pipe 61 and a drain pipe 62. The ozone generator 7 has a liquid inlet pipe 71 and a liquid outlet pipe 72. The connecting channel 31 is connected to the suction pipe 61, the drain pipe 62 is connected to the liquid inlet pipe 71, and the liquid outlet pipe 72 is connected to the water outlet pipe 11. The water outlet pipe 11 is inserted into and fixed to the housing 1, and the water outlet pipe 11 can be integrally formed on the housing 1. The water outlet pipe 11 is preferably vertically arranged. The fluid of ozone and water mixed flows from bottom to top through the water outlet pipe 11. Under the pressure of the water pump 6 and the action of gravity, the high-speed water flow makes the bubbles fully break and disperse, increases the gas-liquid contact area, and at the same time, the violent turbulence accelerates mass transfer, which improves the overall dissolution efficiency and speed of ozone and water to a certain extent.
[0036] Reference Figure 4 and Figure 5 A baffle 8 is installed perpendicular to the flow direction inside the water outlet pipe 11. The baffle 8 can be integrally formed on the inner wall of the water outlet pipe 11. The baffle 8 has an opening 81, and the area of the lower surface of the opening 81 is smaller than the area of its upper surface. The ozone-water mixture collides with the baffle 8, further dispersing the bubbles and prolonging the gas-liquid contact time. The baffle 8 is set perpendicular to the water flow direction, forcing the fluid to flow towards the opening 81, forcing the fluid to redistribute and generating a complex turbulent structure, making the small bubbles more uniformly dispersed throughout the liquid phase, improving the mixing efficiency of ozone and water. Furthermore, the fluid undergoes a process of sudden decrease and then increase in orifice size from bottom to top. The uneven distribution of flow rate and velocity in the vertical direction of the baffle 8 results in a pressure gradient in the vertical direction of the baffle 8. The pressure difference helps to generate strong shear to break the bubbles, increase the gas-liquid contact area, generate strong turbulence to accelerate the mass exchange rate near the gas-liquid interface, and significantly improve the mixing efficiency of ozone and water.
[0037] Reference Figure 5 and Figure 6 The openings 81 are arc-shaped and there are two of them. The two openings 81 are symmetrically arranged, and the arc edges are close to streamlined, which optimizes flow and reduces resistance and energy loss. The arc-shaped openings 81 enhance shear and turbulence generation and reduce bubble impact damage. The spacing of the openings 81 retains more solid material in the baffle 8, increases and disperses the area where bubbles and fluid collide with the baffle 8, and improves the mechanical strength of the baffle 8.
[0038] In this embodiment, the liquid outlet pipe 72 is inserted into the water outlet pipe 11. This design makes the pipe area of the liquid outlet pipe 72 smaller than that of the water outlet pipe 11. Combined with the corresponding setting of the opening 81, this can better improve turbulence generation and further enhance the mixing efficiency of ozone and water. The connection between the liquid outlet pipe 72 and the water outlet pipe 11 should be sealed with a sealing structure such as a sealing ring to ensure airtightness, thereby preventing gas-liquid leakage.
[0039] In one feasible approach, the water outlet pipe 11 and the liquid outlet pipe 72 can also be manufactured by integral molding, or connected by fusion bonding or ultrasonic welding.
[0040] Multiple baffles 8 can be provided, spaced apart in the liquid outlet channel formed by the water outlet pipe 11 and the liquid outlet pipe 72. For example, when there are two baffles 8, they can both be provided in the liquid outlet pipe 72, one can be provided in the water outlet pipe 11 and the other in the liquid outlet pipe 72, or both can be provided in the water outlet pipe 11. This will not be elaborated further here.
[0041] Reference Figure 2 and Figure 3 The filter assembly 2 includes a first filter cartridge 23 and a second filter cartridge 24 coaxially fixedly connected. The inner diameter of the second filter cartridge 24 is smaller than that of the first filter cartridge 23. The first filter cartridge 23 and the second filter cartridge 24 are connected by an annular stepped surface. The first filter cartridge 23 and the second filter cartridge 24 can be fixedly connected by ultrasonic welding or other methods. In a preferred embodiment, the first filter cartridge 23 includes an end face and a side wall, and the second filter cartridge 24 includes an annular stepped surface, a side wall, and an end face. The first filter cartridge 23 and the second filter cartridge 24 are connected to form a cylindrical structure with two diameters, an internal cavity, and holes at both ends. A water inlet 21 is provided on the end face of the first filter cartridge 23, and a water outlet 22 is provided on the end face of the second filter cartridge 24. There can be one water inlet 21 and several water outlets 22. The first filter cartridge 23 and the second filter cartridge 24 can be filled with filter elements of different materials. The filter element in the first filter cartridge 23 can be made of activated carbon, and the filter element in the second filter cartridge 24 can be made of PP cotton. After the external water source flows in through the inlet 21, it passes through two filter elements in sequence. The water source is pretreated through secondary filtration to intercept large solid particles, improve the quality of the effluent, prevent impurities from entering the water pump 6 and causing impurity wear or pipe blockage, and reduce the risk of subsequent ozone generator 7 failure due to water quality issues.
[0042] Reference Figure 2 and Figure 4 The connecting seat 3 is fixed between the second filter cartridge 24 and the water pump 6. Both ends of the connecting seat 3 can be threaded. The second filter cartridge 24 is threaded to one end of the connecting seat 3, and the suction pipe 61 is threaded to the other end of the connecting seat 3. The connecting channel 31 passes through the connecting seat 3. One end of the connecting channel 31 is connected to the water outlet 22, and the other end of the connecting channel 31 is connected to the opening of the suction pipe 61.
[0043] Reference Figure 3 and Figure 4A sealing element 9 is provided between the connecting seat 3 and the second filter cartridge 24. The sealing element 9 is used to seal the end face connection between the connecting seat 3 and the second filter cartridge 24. The sealing element 9 can be made of rubber or silicone. The seal is achieved by the elastic deformation of the sealing material to fill the gap between the contact surfaces. Specifically, the sealing element 9 includes an annular portion 91 and a recessed portion 92. The annular portion 91 is pressed against the end face of the connecting seat 3 by the second filter cartridge 24 to form a planar sealing interface. The side wall of the recessed portion 92 abuts against the pipe wall of the connecting channel 31 to form a radial sealing interface. The planar sealing interface and the radial sealing interface together prevent water leakage at the connection between the second filter cartridge 24 and the connecting seat 3. The bottom of the recessed portion 92 has a through hole to allow water to flow through while maintaining the integrity of the sealing element 9. In addition, sealing rings are provided at the connection between each pipe to prevent liquid leakage.
[0044] Reference Figure 2 and Figure 4 The water quality analyzer 4 directly contacts the filtered water for testing. The water pump 6 operates, drawing water into the suction pipe 61. If the detected water quality parameters exceed a preset threshold, it indicates filter failure or the presence of abnormal impurities in the water source. In this case, the system can trigger an alarm or stop the water pump 6, effectively preventing substandard water from entering the subsequent ozone preparation and mixing stages. The water quality analyzer 4 can specifically employ a TDS analyzer or a turbidity sensor.
[0045] Reference Figure 1 and Figure 3 The power supply module 5 can be a battery, which powers the water pump 6 and the ozone generator 7. A connector 12 is provided on the housing 1 for connecting to an external power source. The battery can be a lithium battery, which can be charged via connector 12 when the battery is low, or it can be used while plugged in. Connector 12 can be a USB-C interface or a DC round interface. The power supply module 5 is integrated with the main body of the device, eliminating the need to find an external power source for outdoor use, making it convenient for outdoor carrying and use.
[0046] The ozone generator 7 is an electrolytic ozone generator that directly generates ozone through the electrolysis of water. The core structure of the ozone generator 7 includes an electrolytic cell, which consists of an anode, a cathode, and a proton exchange membrane. The anode catalyzes the oxidation of water molecules to produce ozone, while the cathode reduces protons to hydrogen. The proton exchange membrane separates the anode and cathode chambers, allowing only H⁺ to pass through to maintain charge balance and prevent an explosion caused by the mixing of ozone and hydrogen. Preferably, the connector 3, water quality analyzer 4, power supply module 5, water pump 6, and ozone generator 7 are installed inside the housing 1 for easy carrying. The housing 1 also serves a protective and sealing function. Alternatively, the water pump 6 can be installed outside the housing 1.
[0047] The implementation principle of an ozone mixing device according to an embodiment of this application is as follows: Water is injected into the first filter cartridge 23 through the inlet hole 21. After the water flows through two filter elements in sequence, it flows out from the outlet hole 22 and enters the connecting channel 31. The water quality tester 4 tests the quality of the filtered water. After the water quality test is qualified, the water pump 6 pumps the filtered water into the suction pipe 61, and then transports it to the ozone generator 7 through the drain pipe 62 and the liquid inlet pipe 71. The ozone generator 7 produces ozone by electrolyzing water. After the ozone and water are mixed, they are transported to the water outlet pipe 11 through the liquid outlet pipe 72. After the ozone and water mixture enters the water outlet pipe 11, it collides with the baffle 8 and undergoes a process in which the aperture of the opening 81 suddenly decreases and then increases. The change in flow rate and pressure difference cause the bubbles to be fully broken and dispersed, the gas-liquid contact area increases and the contact time increases, thereby improving the dissolution efficiency and speed of ozone and water. After the ozone and water are fully mixed to form ozone water, it is pumped out from the outlet of the water outlet pipe 11.
[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
