Description

Disinfection and sterilization machine Technical Field

The present application relates to the technical field of disinfection and sterilization equipment, and in particular to a disinfection and sterilization machine.

Background technique

Ozone is a strong oxidant. When dissolved in water, it forms superoxide water, which can achieve the purpose of sterilization and disinfection directly or through oxidation reaction. High-concentration superoxide water has a killing effect on most bacteria, viruses, molds, fungi, protozoa, and oocysts. The sterilization time is short, and it quickly decomposes into oxygen after disinfection, leaving no residue and no pollution.

Existing disinfection equipment directly passes ozone into water to mix it to form superoxide water, and then sprays the superoxide water to complete the disinfection. However, ozone is not easily soluble in water, and the superoxide water formed by passing ozone into water and directly mixing with water has a poor disinfection effect. After the superoxide water prepared by directly mixing ozone and water is sprayed out of the disinfection equipment, its effective ingredients will leak quickly, resulting in a reduced disinfection and sterilization effect.

The disinfection and sterilization machine 100 of the technical solution of the present application includes a superoxide gas generating mechanism 10, a microbubble injector 20 and a microbubble gas-liquid mixer 30. The superoxide gas generating mechanism 10 is used to inhale air from an air inlet end 111 and prepare ozone. Superoxide is input into a superoxide absorption end 213 of the microbubble injector 20 through a superoxide output end 112. Water is input into the microbubble injector 20 from a liquid inlet end 211 and is preliminarily mixed with superoxide in the microbubble injector 20 to form superoxide water. The superoxide water is input into an input port 311 of the microbubble gas-liquid mixer 30 through a liquid outlet end 212. The superoxide water spiral stirring chamber 34 inside the microbubble gas-liquid mixer 30 whips the superoxide water to increase the dissolution rate of superoxide in the water body, thereby increasing the disinfection and sterilization rate.

The gas prepared by super oxygen gas generating mechanism 10 includes but is not limited to super oxygen, and the type of gas is not limited at this. The liquid entering micro bubble ejector 20 includes but is not limited to water, and can also be other liquids such as ethanol, hydrogen peroxide, and the type of liquid is not limited at this. What disinfection and sterilization machine 100 outputs includes but is not limited to super oxygen water, and can also be the micro bubble gas-liquid mixture of chlorine and water, the micro bubble gas-liquid mixture of chlorine dioxide and water, and the type of disinfection and sterilization machine 100 output liquid is not limited at this.

In order to increase the service life of the micro-bubble injector 20 , a stainless steel anti-blocking net (not shown) is further provided at the liquid inlet end 211 to prevent impurities in the liquid from entering the micro-bubble injector 20 and causing blockage.

1 to 4, in one embodiment of the present application, the microbubble injector 20 includes:

A first tube body 21, wherein the first tube body 21 is formed with the liquid inlet end 211, the liquid outlet end 212 and the superoxide absorption end 213, the liquid inlet end 211 and the liquid outlet end 212 are arranged opposite to each other and are connected to form a first compression chamber 22, the liquid outlet end 212 is connected to the input port 311, and the superoxide absorption end 213 is connected to the side wall of the first compression chamber 22; and

The negative pressure mechanism 23 is disposed on the side wall of the first compression chamber 22 and is arranged opposite to the superoxide absorption end 213 .

In the technical solution of an embodiment of the present application, the microbubble injector 20 includes a first tube body 21 and a negative pressure mechanism 23. A first compression chamber 22 is formed inside the first tube body 21. The negative pressure mechanism 23 is arranged on the side wall of the first compression chamber 22 and is arranged opposite to the superoxide absorption end 213. The negative pressure mechanism 23 is arranged toward the superoxide absorption end 213 to form a negative pressure to absorb superoxide gas into the first compression chamber 22 and mix it with the liquid in the first compression chamber 22 to dissolve it in the liquid. The design of the negative pressure mechanism 23 improves the dissolution rate of superoxide gas in the liquid, thereby improving the disinfection and sterilization rate of the disinfection and sterilization machine 100.

1 to 4 , in one embodiment of the present application, the first compression chamber 22 includes a first pipe segment 221, a second pipe segment 222 and a third pipe segment 223 which are connected in sequence, the first pipe segment 221 is connected to the liquid inlet end 211, the second pipe segment 222 is connected to the superoxide absorption end 213, the third pipe segment 223 is connected to the liquid outlet end 212, and the inner diameters of the first pipe segment 221 and the third pipe segment 223 are both larger than the inner diameter of the second pipe segment 222.

In the technical scheme of an embodiment of the present application, the third pipe section 223 is also called the first injection mixing chamber 223, and the inner diameters of the first pipe section 221 and the third pipe section 223 are both larger than the second pipe section 222. When the liquid flows from the first pipe section 221 through the second pipe section 222 and the third pipe section 223 in sequence, a Venturi effect is formed. The Venturi effect refers to the phenomenon that the flow velocity of the fluid increases when the restricted flow passes through the reduced flow section, and its flow velocity is inversely proportional to the flow section. When the superoxide gas enters the second pipe section 222 from the superoxide suction end 213 and mixes with the liquid, the strong liquid mixes with the superoxide gas and is ejected from the third pipe section 223, so that the mixing of the superoxide gas and the liquid is more uniform and more complete, and the bubbles generated in the liquid are more and more delicate, thereby improving the dissolution rate and dissolution efficiency of the superoxide gas in the liquid, thereby improving the conversion rate of the superoxide gas, thereby improving the disinfection and sterilization rate of the disinfection and sterilization machine 100.

1 to 4, in one embodiment of the present application, the second pipe segment 222 includes a first sub-pipe segment 2221 and a second sub-pipe segment 2222 that are connected in sequence, the end of the first sub-pipe segment 2221 away from the second sub-pipe segment 2222 is connected to the first pipe segment 221, the end of the second sub-pipe segment 2222 away from the first sub-pipe segment 2221 is connected to the third pipe segment 223, and the superoxide absorption end 213 is provided at the connection between the first sub-pipe segment 2221 and the second sub-pipe segment 2222;

The inner diameter of the first sub-tube segment 2221 gradually decreases in a direction away from the first tube segment 221 .

In the technical solution of one embodiment of the present application, in the Venturi effect, the flow rate of the liquid is inversely proportional to the flow cross-section. The smaller the inner diameter of the flow cross-section, the faster the flow rate. The inner diameter of the second pipe segment 222 is smaller than the first pipe segment 221. In order to reduce the resistance between the liquid and the inside of the second pipe segment 222 to gradually increase the flow rate of the liquid, the inner diameter of the second pipe segment 222 is gradually reduced in the direction away from the first pipe segment 221, so that a buffer structure is formed, which reduces the wear of the liquid on the wall of the first tube body 21 and improves the stability of the internal structure of the microbubble injector 20.

1 to 4 , in an embodiment of the present application, the inner diameter of the second sub-tube segment 2222 gradually decreases in a direction away from the third tube segment 223 .

In the technical solution of an embodiment of the present application, after the superoxide gas is dissolved in the liquid, a high-pressure water column is formed and ejected from the second sub-pipe segment 2222. In order to maintain the pressure of the high-pressure water column and keep the shape of the water column unaffected, the inner diameter of the second sub-pipe segment 2222 increases in a direction away from the first sub-pipe segment 2221. The design of the second sub-pipe segment 2222 improves the disinfection and sterilization rate of the disinfection and sterilization machine 100.

1 to 4 , in one embodiment of the present application, the microbubble injector 20 further includes an anti-seepage mechanism 24 , which is disposed in the first compression chamber 22 and is used to unidirectionally conduct superoxide gas from the superoxide absorption end 213 into the first compression chamber 22 .

In the technical solution of an embodiment of the present application, in order to prevent the superoxide gas generating mechanism 10 from stopping injecting gas into the superoxide inhalation end 213 when the machine is shut down, and the liquid in the first compression chamber 22 from flowing back into the superoxide gas generating mechanism 10 from the superoxide inhalation end 213, an anti-seepage mechanism 24 is arranged in the microbubble injector 20. The anti-seepage mechanism 24 is used to conduct gas unidirectionally, so that the gas can only enter the first compression chamber 22 from the superoxide inhalation end 213, and prevent the liquid from flowing back out of the superoxide inhalation end 213 from the first compression chamber 22, thereby improving the stability of the internal structure of the disinfection and sterilization machine 100.

1 to 4 , in one embodiment of the present application, the anti-seepage mechanism 24 includes:

A main body 241, the main body 241 is covered with the superoxygen absorption end 213, an anti-seepage channel 2411 connected to the superoxygen absorption end 213 is formed inside the main body 241, and the main body 241 is formed with the air outlet 2412 on the side facing the negative pressure mechanism 23, and the anti-seepage channel 2411 is connected to the first compression chamber 22 through the air outlet 2412;

In the technical solution of an embodiment of the present application, when the superoxide gas generating mechanism 10 injects superoxide gas into the microbubble injector 20, the gas enters the anti-seepage channel 2411 from the superoxide absorption end 213, and pushes the seal 243 to move toward the gas outlet 2412, and the elastic member 244 connected to the seal 243 is compressed. At this time, the superoxide gas enters the microbubble injector 20 without being blocked by the seal 243;

When the superoxide gas generating mechanism 10 stops injecting gas into the microbubble injector 20, the elastic member 244 pushes the sealing member 243 to move toward the sealing gasket 242 and abut against the sealing gasket 242 to close the superoxide absorption end 213. After the liquid enters the anti-seepage channel 2411 from the air inlet, the sealing member 243 will also be abutted against the superoxide absorption end 213. The design of the anti-seepage mechanism 24 improves the stability of the internal structure of the microbubble injector 20.

The sealing member 243 may be a tetrafluoro ball, and the sealing gasket 242 may be a fluorine pad. The materials of the sealing member 243 and the sealing gasket 242 are not limited here.

When the high-speed microbubble gas-liquid mixture is ejected from the microbubble ejector 20, it hits the spiral blade 33, forming an external force to make the spiral blade 33 start to rotate, and the superoxide microbubble gas-liquid mixture is whipped to improve the mixing efficiency of the superoxide microbubble gas-liquid, that is, to improve the dissolution rate of superoxide gas in liquid, to increase the content of superoxide effective components in the liquid, thereby improving the disinfection and sterilization rate of the disinfection and sterilization machine 100.
