Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of medical instrument equipment, and specifically relates to a portable ozone water therapeutic instrument. BACKGROUND

[0002] Ozone (O3) is a strong oxidant and has strong bactericidal, disinfecting and deodorizing functions. In medical treatment, ozone is used to mix with water to generate medical ozone water, and the medical ozone water has very strong oxidizing property, can rapidly destroy the cell structure of microorganisms such as bacteria and viruses, so as to achieve the effect of sterilization and disinfection, and the residual ozone can be rapidly converted into oxygen, without causing secondary pollution.

[0003] The ozone water therapeutic instrument is a device for mixing ozone and water solution to form ozone water. At present, the methods for mixing ozone and water to generate medical ozone water mainly include electrolysis method, aeration method, Venturi jet method and turbine negative pressure method. The Venturi jet method is to use the water flowing in the pipeline to change the diameter of the device to accelerate the flow rate to become negative pressure air suction, and the ozone is mixed with the water in the pipeline. This way can make the ozone efficiently mix with the water and improve the solubility of ozone in water.

[0004] However, the Venturi jet device may have a backflow failure after long-time use, such as due to excessive downstream pressure, too low liquid flow rate, pressure fluctuation and the like, so that part or all of the liquid will flow back to the air inlet, which not only affects the mixing effect, but also causes the liquid to enter the front-end ozone generator to damage the components and cause safety risks.

The ozone electromagnetic valve is used for opening or closing the ozone gas passage and controlling the ozone flow. The ozone buffer box is used for storing the backflow liquid, and the capacitive induction switch is used for sensing whether the liquid exists in the ozone buffer box and transmitting an electric signal to the ozone electromagnetic valve so as to control the opening and closing of the ozone electromagnetic valve in an emergency state.

[0012] Further, the ozone buffer box comprises a containing cavity and a one-way valve, and the one-way valve is arranged at a gas input port end of the containing cavity. The one-way valve can allow the ozone gas to enter the containing cavity, but the backflow liquid in the containing cavity cannot enter the ozone generating unit through the one-way valve.

[0013] Further, the one-way valve comprises a sealing ring, a spring and a valve flap, the sealing ring is used for sealing between the valve flap and a cavity wall of the one-way valve, and the spring is clamped between the cavity wall of the one-way valve and the valve flap. The valve flap is abutted at the gas inlet of the ozone buffer box under the action of the spring, when the ozone gas is delivered into the ozone buffer box, the valve flap is pushed away by overcoming the action force of the spring, so that the ozone can enter the containing cavity smoothly. When the backflow liquid acts on the valve flap in the opposite direction, the valve flap is abutted on the sealing ring to achieve the sealing effect, and the backflow liquid cannot enter the ozone generating unit.

[0014] Further, a plurality of liquid level switches are arranged on the side wall of the ozone water tank along the height direction. The liquid level switches are used for sensing the ozone water liquid level in the ozone water tank.

[0015] Further, a flow switch is arranged between the booster water pump and the liquid outlet. The flow switch can detect the flow condition of the ozone water in the pipeline and find the flow abnormality in the pipeline.

[0016] Further, a tail oxygen outlet is arranged on the side wall of the ozone water tank. The tail oxygen outlet is used for balancing the gas pressure in the ozone water tank and discharging the un-mixed or overflow ozone gas.

[0017] Compared with the prior art, the ozone water tank has the following beneficial effects:

[0018] The aqueous solution enters the gas-liquid mixer through the water inlet and the integrated valve, negative pressure is generated at the gas inlet end of the gas-liquid mixer when the aqueous solution passes through the gas-liquid mixer, ozone produced by the ozone generating unit is sucked and mixed to form ozone water. When the gas pressure fluctuates in the gas-liquid mixing unit and backflow occurs, the ozone water is abutted in the anti-backflow device, so that the backflow is prevented from entering the ozone generating unit and causing damage to components.

[0026] Obviously, the drawings in the following description are only some examples or embodiments of the present application, and for those of ordinary skill in the art, the present application can also be applied to other similar situations without creative labor. In addition, it can be understood that although the efforts made in this development process may be complex and lengthy, for those of ordinary skill in the art related to the content disclosed in the present application, some design, manufacture or production changes based on the technical content disclosed in the present application are only routine technical means, and should not be understood as insufficient disclosure of the present application.

[0027] However, there are cases where unnecessary detailed description is omitted. For example, there are cases where detailed description of matters well known, repeated description of actually identical structures is omitted. This is to avoid the following description unnecessarily becoming lengthy and facilitate understanding by those skilled in the art. In addition, the drawings and the following description are provided to enable those skilled in the art to fully understand the present application and are not intended to limit the subject matter recited in the claims.

[0028] Referring to Figures 1-2 The utility model discloses an ozone water therapeutic instrument, which comprises an ozone generating unit 1, a gas-liquid mixing unit 2, a backflow prevention device 3 and an oxygen generating unit 4. The ozone generating unit 1 is used for generating ozone. The gas-liquid mixing unit 2 comprises a water inlet 21, an integrated valve 22, a gas-liquid mixer 23, an ozone water tank 24, a booster water pump 25 and a liquid outlet 26 connected in sequence. The ozone generating unit 1 is communicated with the gas-liquid mixer 23 through the backflow prevention device 3. The oxygen generating unit 4 is communicated with the ozone generating unit 1.

[0029] The water inlet 21 is connected with a water inlet decoration piece outside the shell of the ozone water therapeutic instrument through a waterway pipe, and the water inlet outside the shell is connected with a water heater or a constant temperature water source. The integrated valve 22 is an electromagnetic integrated valve with a flow meter, which is used for measuring the water flow in the pipeline of the water inlet 21 and controlling the switch of the water inlet. The gas-liquid mixer 23 is a Venturi jet, and the water solution enters the water inlet end of the gas-liquid mixer 23 and is output from the water outlet end, and when passing through, a negative pressure is formed at the air inlet end to suck ozone, and after the ozone is mixed with the water, ozone water is formed and stored in the ozone water tank 24. When the ozone water therapeutic instrument is turned on, the booster water pump 25 starts to extract ozone water from the ozone water tank 24 and discharges the ozone water from the liquid outlet 26 to supply the patient with treatment. The oxygen generating unit 4 is a medical molecular sieve oxygen generator, which inputs oxygen gas after generating the oxygen gas into the ozone generating unit 1 to generate ozone gas, and the ozone gas enters the gas-liquid mixer 23 to be mixed with the water through the backflow prevention device 3. When the gas-liquid mixer 23 has backflow, the backflow prevention device 3 can block the ozone water from entering the ozone generating unit 1, thereby protecting the components.

[0030] Specifically, referring to Figure 1 , Figure 2 and Figure 3As shown, the backflow prevention device 3 includes an ozone solenoid valve 31, an ozone buffer box 32, and a capacitive sensing switch 33. The ozone solenoid valve 31 is used to open or close the passage of ozone gas flow. When backflow occurs, the backflow solution enters the ozone buffer box 32, and the enlarged inner cavity of the ozone buffer box 32 reduces the flow speed of the backflow, avoiding the solution from entering the ozone generation unit 1 instantaneously due to the too fast backflow. The capacitive sensing switch 33 can detect whether there is backflow solution in the ozone buffer box 32. When there is backflow solution, the capacitive sensing switch 33 controls the ozone solenoid valve 31 to be closed, so that the backflow cannot continue to enter the ozone buffer box 32, and the ozone gas cannot be input into the gas-liquid mixer 23.

[0031] In one embodiment, the ozone buffer box 32 is made of polytetrafluoroethylene, which has excellent ozone resistance.

[0032] Further, as shown in Figure 1 and Figure 4 , the ozone buffer box 32 includes a containing cavity 321 and a one-way valve 322, which is arranged at the gas input end of the containing cavity 321. The containing cavity 321 is used to contain the backflow liquid, and the enlarged volume slows down the speed of the backflow. In the normal use state, the containing cavity 321 does not affect the output speed of the ozone gas. The one-way valve 322 has a one-way flow effect, which can allow ozone gas to enter the containing cavity 321 and can prevent backflow liquid from entering the ozone generation unit 1.

[0033] Further, the one-way valve 322 includes a sealing ring 3221, a spring 3222, and a valve flap 3223. The sealing ring 3221 is a fluorine rubber O-ring arranged on the air inlet cavity wall in the inner cavity of the one-way valve 322, which has good ozone corrosion resistance. The valve flap 3223 is a round sheet or a ball, which is stopped on the sealing ring 3221 by the deformation potential energy of the spring 3222. In the normal use state, the ozone gas pressure can overcome the pressure of the spring 3222 to push away the valve flap 3223, so that the ozone gas can normally flow. When backflow occurs, the backflow liquid acts on the valve flap 3223 in the opposite direction, and the valve flap 3223 is stopped on the sealing ring 3221, and the sealing ring 3221 is deformed to achieve full sealing.

[0034] In one embodiment, as shown in Figure 1 and Figure 2 , the side wall of the ozone water tank 24 is provided with a plurality of liquid level switches 27 along the height direction. The liquid level switch 27 is a non-contact capacitive liquid level sensor. The liquid level switch 27 is arranged on the side wall of the ozone water tank 24 and is divided into upper, middle, and lower positions. The three liquid level switches 27 are located at 85%, 50%, and 20% of the volume of the ozone water tank 24, respectively.

[0035] When the one-key start switch is opened, the state of the three liquid level switches 27 in the ozone water tank 24 is first determined. If the liquid level indicates that the ozone water tank 24 is at a high liquid level, only the oxygen production unit 4 and the booster water pump 25 are opened, and ozone water treatment liquid is output, and other elements do not participate in the work. The oxygen production unit 4 continuously outputs oxygen to the gas-liquid mixer 23 to prevent water return in the gas path. If the liquid level indicates that the ozone water tank 24 is at a medium liquid level, a low liquid level, or an empty liquid level, the oxygen production unit 4 is first opened to generate oxygen, which is used to connect the gas path to prevent water return. After 3 seconds, the ozone generation unit 1 and the integrated valve 22 are opened, and ozone and water begin to mix to generate ozone water to the ozone water tank 24 for replenishment, and the cycle is repeated in turn.

[0036] The booster water pump 25 and the liquid outlet 26 are provided with a flow switch 28. The flow switch 28 can measure the flow of the water outlet pipe of the liquid outlet 26. When the ozone water treatment liquid is output, if there is an abnormality such as blockage, the flow switch 28 outputs the flow abnormality information to the main control system, and the booster water pump 25 is closed, and after 5 seconds, the booster water pump 25 is opened again. If the abnormal signal still exists after three cycles, it is considered that the abnormality cannot be solved, and the abnormality is output to the human-computer interaction interface and the machine is stopped to prompt the user.

[0037] The side wall of the ozone water tank 24 is provided with a tail oxygen outlet 29, which is connected with a tail oxygen outlet decoration piece outside the shell. When installed, the outlet is connected with a pipeline to the outside or an ozone tail gas destroyer. The tail oxygen outlet 29 can be installed with a pressure limiting valve. When the tail gas pressure in the ozone water tank 24 is too high without mixing or overflow, it may cause water return, so the tail oxygen outlet 29 can balance the internal and external gas pressure of the ozone water tank 24.

[0038] It should be noted that the present application is not limited to the above-mentioned embodiments. The above-mentioned embodiments are only examples, and embodiments having the same technical idea and playing the same role and effect within the scope of the technical solution of the present application are all included in the technical scope of the present application. In addition, within the scope of the main idea of the present application, various modifications of the embodiments that can be thought of by those skilled in the art, and other ways constructed by combining part of the constituent elements in the embodiments are also included in the scope of the present application.
