Description

Technical fields:

[0001] This utility model relates to the field of ozone water preparation technology, and in particular to an ozone water preparation device. Background technology:

[0002] Ozone water has extremely strong oxidizing properties and is a broad-spectrum disinfectant. It can kill bacteria and viruses on object surfaces, remove pesticide residues from fruits and vegetables, and causes no secondary pollution. Ozone water is widely used in fields such as medical disinfection, food processing, and water treatment.

[0003] Most existing ozone water preparation devices on the market simply consist of a gas-liquid mixing pump, an ozone gas supply device, and a water supply device. The gas-liquid mixing pump includes an inlet, a liquid inlet, and a liquid outlet. The ozone gas supply device is connected to the inlet of the gas-liquid mixing pump, and the water supply device is connected to the liquid inlet. The ozone water produced after mixing is directly supplied from the liquid outlet of the gas-liquid mixing pump. Although existing ozone water preparation devices can be used to prepare and supply ozone water, in some applications where frequent interruptions in ozone water use are required, not only is it necessary to frequently start and stop the gas-liquid mixing pump and the ozone gas supply device, which can easily affect their service life, but the ozone water concentration cannot be guaranteed. There is an urgent need for an ozone water preparation device that is better suited for applications requiring frequent interruptions in ozone water use. Utility Model Content:

[0004] The purpose of this invention is to provide an ozone water preparation device that addresses the shortcomings of existing technologies. This device eliminates the need for frequent start-stop operations of the gas-liquid mixing pump and the ozone gas supply device, ensuring their lifespan. Furthermore, it guarantees that the supplied ozone water concentration remains consistently high, making it more suitable for applications requiring frequent interruptions in the use of ozone water.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an ozone water preparation device, comprising a gas-liquid mixing pump, an ozone gas supply device, and a water supply device. The gas-liquid mixing pump includes an air inlet, a liquid inlet, and a liquid outlet. The ozone gas supply device is connected to the air inlet of the gas-liquid mixing pump. The device also includes a buffer tank and a liquid outlet pipe. The buffer tank includes a first liquid inlet, a first liquid outlet, a second liquid inlet, and a second liquid outlet. The water supply device is connected to the first liquid inlet of the buffer tank. The first liquid outlet of the buffer tank is connected to the liquid inlet of the gas-liquid mixing pump. The liquid outlet of the gas-liquid mixing pump is connected to the second liquid inlet of the buffer tank. The liquid outlet pipe is connected to the second liquid outlet of the buffer tank. An ozone water valve is connected in series on the liquid outlet pipe.

[0006] A further improvement to the above scheme is that the buffer tank is equipped with an ozone water delivery pipe, one end of which is connected to the second liquid inlet of the buffer tank, and the other end of which is connected to the second liquid outlet of the buffer tank. Several overflow holes are formed on the ozone water delivery pipe, and the ozone water delivery pipe is connected to the inside of the buffer tank through the overflow holes.

[0007] A further improvement to the above scheme is that each of the overflow holes is located close to the second liquid outlet.

[0008] A further improvement to the above scheme is that the first liquid inlet is located at the top right side of the buffer tank, the first liquid outlet is located at the bottom left side of the buffer tank, the second liquid inlet is located at the top left side of the buffer tank, and the second liquid outlet is located at the bottom right side of the buffer tank.

[0009] A further improvement to the above solution is that the present invention also includes an ozone water concentration detector for detecting the concentration of ozone water in the outlet pipe.

[0010] A further improvement to the above scheme is that a pump inlet valve is connected in series between the ozone gas supply device and the inlet end of the gas-liquid mixing pump.

[0011] A further improvement to the above scheme is that a water supply valve is connected in series between the water supply device and the first inlet of the buffer tank.

[0012] A further improvement to the above scheme is that a pump inlet valve is connected in series between the first liquid outlet of the buffer tank and the liquid inlet of the gas-liquid mixing pump.

[0013] A further improvement to the above scheme is that a pump outlet valve is connected in series between the outlet end of the gas-liquid mixing pump and the second inlet of the buffer tank.

[0014] The beneficial effects of this utility model are as follows: This utility model provides an ozone water preparation device, including a gas-liquid mixing pump, an ozone gas supply device, and a water supply device. The gas-liquid mixing pump includes an air inlet, a liquid inlet, and a liquid outlet. The ozone gas supply device is connected to the air inlet of the gas-liquid mixing pump. It also includes a buffer tank and a liquid outlet pipe. The buffer tank includes a first liquid inlet, a first liquid outlet, a second liquid inlet, and a second liquid outlet. The water supply device is connected to the first liquid inlet of the buffer tank. The first liquid outlet of the buffer tank is connected to the liquid inlet of the gas-liquid mixing pump. The liquid outlet of the gas-liquid mixing pump is connected to the second liquid inlet of the buffer tank. The liquid outlet pipe is connected to the second liquid outlet of the buffer tank. An ozone water valve is connected in series on the liquid outlet pipe.

[0015] In preparing and supplying ozone water, this invention first introduces water into a buffer tank via a water supply device. The water in the buffer tank flows into a gas-liquid mixing pump from the first outlet of the buffer tank. Then, ozone gas is introduced into the gas-liquid mixing pump via an ozone gas supply device. The gas-liquid mixing pump mixes the ozone water to produce ozone water. The ozone water produced by the gas-liquid mixing pump flows into the buffer tank from the second inlet of the buffer tank. When the ozone water valve is opened, the ozone water in the buffer tank flows sequentially through the second outlet and the outlet pipe of the buffer tank and is supplied externally. When the ozone water valve is closed, the excess ozone water in the buffer tank flows back into the gas-liquid mixing pump from the first outlet of the buffer tank for re-mixing. Compared with existing ozone water preparation devices on the market, this invention not only eliminates the need for frequent start-stop operations of the gas-liquid mixing pump and the ozone gas supply device, thus ensuring a longer service life for the gas-liquid mixing pump and the ozone gas supply device, but also ensures that the concentration of the supplied ozone water remains consistently high. This makes it more suitable for applications requiring frequent interruptions in the use of ozone water. Attached image description:

[0018] The present invention will be further described below with reference to the accompanying drawings, such as... Figure 1As shown, this utility model includes a gas-liquid mixing pump 2, an ozone gas supply device 1, and a water supply device 3. The gas-liquid mixing pump 2 includes an air inlet 21, a liquid inlet 22, and a liquid outlet 23. The ozone gas supply device 1 is connected to the air inlet 21 of the gas-liquid mixing pump 2. It also includes a buffer tank 4 and a liquid outlet pipe 5. The buffer tank 4 includes a first liquid inlet 41, a first liquid outlet 42, a second liquid inlet 43, and a second liquid outlet 44. The water supply device 3 is connected to the first liquid inlet 43 of the buffer tank 4. The buffer tank 4 is connected to the first outlet 42 of the buffer tank 4, which is connected to the inlet 22 of the gas-liquid mixing pump 2. The outlet 23 of the gas-liquid mixing pump 2 is connected to the second inlet 43 of the buffer tank 4. The outlet pipe 5 is connected to the second outlet 44 of the buffer tank 4, and an ozone water valve 6 is connected in series on the outlet pipe 5. In preparing and supplying ozone water, water is first fed into the buffer tank 4 through the water supply device 3, and the water in the buffer tank 4 flows into the buffer tank 4 from the first outlet 42. In the gas-liquid mixing pump 2, ozone gas is supplied to the gas-liquid mixing pump 2 through the ozone gas supply device 1. Ozone water is produced by mixing in the gas-liquid mixing pump 2. The ozone water produced by the gas-liquid mixing pump 2 flows into the buffer tank 4 from the second inlet 43. When the ozone water valve 6 is opened, the ozone water in the buffer tank 4 flows through the second outlet 44 and the outlet pipe 5 of the buffer tank 4 in sequence and is supplied to the outside. When the ozone water valve 6 is closed, the excess ozone water in the buffer tank 4 will flow back to the gas-liquid mixing pump 2 from the first outlet 42 of the buffer tank 4 for re-mixing. Compared with the existing ozone water preparation devices on the market, this utility model not only eliminates the need for frequent start-stop of the gas-liquid mixing pump 2 and the ozone gas supply device 1, but also ensures a longer service life for the gas-liquid mixing pump 2 and the ozone gas supply device 1. In addition, it can ensure that the concentration of the supplied ozone water is always maintained at a high level, making it more suitable for occasions where frequent interruptions in the use of ozone water are required.

[0019] The buffer tank 4 is equipped with an ozone water delivery pipe 7. One end of the ozone water delivery pipe 7 is connected to the second inlet 43 of the buffer tank 4, and the other end is connected to the second outlet 44 of the buffer tank 4. Several overflow holes 71 are formed on the ozone water delivery pipe 7, and the ozone water delivery pipe 7 communicates with the inside of the buffer tank 4 through the overflow holes 71. Because the concentration of ozone water obtained after mixing by the gas-liquid mixing pump 2 is higher than the concentration of ozone water in the buffer tank 4, compared to the concentration obtained after mixing by the gas-liquid mixing pump... The higher concentration of ozone water obtained by mixing is diluted with the ozone water in the buffer tank 4 and then flows out from the second outlet 44 for supply. By setting the ozone water delivery pipe 7, the higher concentration of ozone water obtained by mixing by the gas-liquid mixing pump 2 can flow directly to the second outlet 44 of the buffer tank 4, that is, ozone water is supplied outward first, and the excess ozone water will flow into the buffer tank 4 from the overflow hole 71, which can further increase the concentration of ozone water supplied outward.

[0020] Each of the overflow holes 71 is located close to the second liquid outlet 44, which can further ensure that the high-concentration ozone water that has just been mixed by the gas-liquid mixing pump 2 flows directly to the second liquid outlet 44 of the buffer tank 4 so as to supply the high-concentration ozone water to the outside.

[0021] The first inlet 41 is located at the top right side of the buffer tank 4, the first outlet 42 is located at the bottom left side of the buffer tank 4, the second inlet 43 is located at the top left side of the buffer tank 4, and the second outlet 44 is located at the bottom right side of the buffer tank 4. The overall structural layout is more reasonable and can better ensure that the ozone water supplied to the outside maintains a high concentration.

[0022] This utility model also includes an ozone water concentration detector 8 for detecting the concentration of ozone water in the outlet pipe 5. By detecting the concentration of ozone water in the outlet pipe 5 using the ozone water concentration detector 8, it is possible to better ensure that the concentration of the supplied ozone water meets the standard.

[0023] An inlet valve 9 is connected in series between the ozone gas supply device 1 and the inlet end 21 of the gas-liquid mixing pump 2. The inlet valve 9 can control whether the ozone gas from the ozone gas supply device 1 is introduced into the gas-liquid mixing pump 2.

[0024] A water supply valve 10 is connected in series between the water supply device 3 and the first liquid inlet 41 of the buffer tank 4. The water supply valve 10 can control whether the water supply device 3 sends the water required for the preparation of ozone water into the buffer tank 4.

[0025] A pump inlet valve 11 is connected in series between the first outlet 42 of the buffer tank 4 and the inlet 22 of the gas-liquid mixing pump 2. The pump inlet valve 11 can control whether the water in the buffer tank 4 flows into the gas-liquid mixing pump 2.

[0026] A pump outlet valve 12 is connected in series between the outlet end 23 of the gas-liquid mixing pump 2 and the second inlet 43 of the buffer tank 4. The pump outlet valve 12 can control whether the ozone water prepared by the gas-liquid mixing pump 2 flows into the buffer tank 4.

[0027] Working principle:

[0028] First, water is supplied to the buffer tank 4 through the water supply device 3. The water in the buffer tank 4 flows into the gas-liquid mixing pump 2 from the first outlet 42 of the buffer tank 4. Then, ozone gas is supplied to the gas-liquid mixing pump 2 through the ozone gas supply device 1. The gas-liquid mixing pump 2 mixes the gases to produce ozone water. The ozone water produced by the gas-liquid mixing pump 2 flows into the buffer tank 4 from the second inlet 43 of the buffer tank 4. When the ozone water valve 6 is opened, the ozone water in the buffer tank 4 flows sequentially through the second outlet 44 and the outlet pipe 5 of the buffer tank 4 and is supplied to the outside. When the valve 6 is closed... When the ozone water valve 6 is activated, excess ozone water in the buffer tank 4 will flow back from the first outlet 42 of the buffer tank 4 to the gas-liquid mixing pump 2 for re-mixing. Compared with existing ozone water preparation devices on the market, this invention not only eliminates the need for frequent start-stop of the gas-liquid mixing pump 2 and the ozone gas supply device 1, but also ensures a longer service life for the gas-liquid mixing pump 2 and the ozone gas supply device 1. Furthermore, it ensures that the concentration of the supplied ozone water remains high, making it more suitable for applications that require frequent interruptions in the use of ozone water.

[0029] Of course, the above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
