The application is described below with reference to specific embodiments in conjunction with the accompanying drawings:

example 1

Referring to fig. 1 to 4, an embodiment of the present application discloses a sterilizing apparatus, which includes a housing 600, an atomizing tube 100, an air pump 200, a plasma generating part 300, and a water pipe 400. The sterilizing device can generate atomized ozone water to sterilize pollutants in the environment.

Wherein the housing 600 is a base member of the disinfection apparatus of the present application, the housing 600 may provide a mounting base for and serve the purpose of protecting at least some other components of the disinfection apparatus. The housing 600 may be made of engineering plastic, so that the housing 600 has a certain structural strength, and the mass of the housing 600 may be relatively light, so that the overall mass of the disinfection device of the present application is light, which is beneficial to moving and transporting the disinfection device, or integrating the disinfection device into other devices. Specifically, the housing 600 may be made of thermoplastic polymer materials such as ABS. Of course, in order to make the structural strength of the housing 600 better, the housing 600 may be made of a metal material, and an insulating layer may be provided on the inner wall of the housing 600 to prevent leakage, and the specific material of the housing 600 is not limited in the present application.

The air pump 200 of the present application is connected to the plasma generating part 300, the air pump 200 can supply air to the plasma generating part 300, and the plasma generating part 300 can discharge air supplied from the air pump 200 to the plasma generating part 300 to ionize the air to form ozone. It should be understood that in the related art, the plasma generating device may be provided with two electrodes, one of the two electrodes may be connected to a first preset voltage, the other of the two electrodes may be grounded, or connected to a second preset voltage lower than the first preset voltage, so that a voltage difference may be formed between the two electrodes, thereby forming a discharge region, and the gas in the discharge region may be ionized to form plasma and ozone.

Specifically, after the gas pump 200 of the present application inputs the gas into the plasma generating part 300, the gas introduced into the plasma generating part 300 by the gas pump 200 may pass through the discharge region in the plasma generating part 300, so that the gas is ionized in the discharge region of the plasma generating part 300 to form plasma and ozone. The air pump 200 continuously supplies air into the plasma generating unit 300, and plasma and ozone can be continuously generated when the plasma generating unit 300 is energized.

The atomizing tube 100 of the present application is connected to the plasma generating part 300, and specifically, both ends of the plasma generating part 300 may be connected to the air pump 200 and the atomizing tube 100, respectively, and the air introduced into the plasma generating part 300 by the air pump 200 may pass through the discharge region of the plasma generating part 300 to form plasma and ozone. Meanwhile, since the gas supplied from the gas pump 200 to the plasma generating part 300 has a certain flow rate, in the case where the gas is continuously supplied from the gas pump 200 to the plasma generating part 300, the gas having the flow rate can be continuously moved into the atomizing tube 100 connected to the plasma generating part 300 after being ionized to form ozone.

The water pipe 400 is communicated with the atomizing pipe 100, the water pipe 400 can inject liquid into the atomizing pipe 100, the liquid can be mixed with ozone input into the atomizing pipe 100 by the plasma generating part 300 after entering the atomizing pipe 100 to form ozone water, and then the ozone water is sprayed into the environment in a spray mode through the atomizing pipe 100, so that the aim of sterilizing pollutants in the environment is fulfilled. It should be understood that the liquid injected into the atomizing tube 100 by the water pipe 400 may be clear water or a solution to which other disinfectant is added.

Specifically, the atomizing tube 100 of the present disclosure may be configured to include a first tube part 110, a second tube part 120, and a third tube part 130, wherein the first tube part 110, the second tube part 120, and the third tube part 130 are sequentially connected to form an integral structure. Wherein the first pipe portion 110, the second pipe portion 120 and the third pipe portion 130 are hollow pipes, the channels in the first pipe portion 110, the second pipe portion 120 and the third pipe portion 130 are communicated, and the first pipe portion 110 is communicated with the plasma generating portion 300 so that ozone can be input into the atomizing pipe 100; the water pipe 400 is provided to communicate with the second pipe portion 120 so that clean water or an aqueous solution can be inputted into the atomizing pipe 100. The third pipe portion 130 is provided with a spray opening 131, and ozone water formed in the atomizing pipe 100 can be sprayed through the spray opening 131.

Wherein the inner diameter of the second tube part 120 is smaller than the inner diameter of the first tube part 110 and the inner diameter of the third tube part 130, and the inner diameter of the first tube part 110 is set to be gradually reduced in the extending direction of the first tube part 110 to the second tube part 120 so that the outer diameter of the channel in the first tube part 110 is gradually reduced, thus the channel in the atomizing tube 100 of the present application has a structure in which the inner diameter is firstly reduced and then increased. Therefore, the first, second and third pipe parts 110, 120 and 130 of the present application have the venturi-like structure with the above-mentioned structural arrangement, and the ozone inputted into the atomizing pipe 100 from the plasma generating part 300 can suck the water in the water pipe 400 into the atomizing pipe 100 by the siphon effect, so that the ozone and the water are mixed in the atomizing pipe 100 to form ozone water, and finally, the ozone water is sprayed in a spray form through the spray opening 131 of the third pipe part 130. The atomized ozone water has good adhesion performance, so that the atomized smoke water has good disinfection effect on air pollutants in the environment and pollutants on the surfaces of objects after being sprayed in the environment.

It will be appreciated that in the sterilizing apparatus of the present application, the gas input to the plasma generating unit 300 through the gas pump 200 can provide a gas source for ozone generated by the plasma generating unit 300, the gas pump 200 also pushes ozone generated by the plasma generating unit 300 to flow into the atomizing tube 100, thereby sucking liquid into the atomizing tube 100 through the water pipe 400 to be mixed with ozone, and thus no additional power device is required to be provided for inputting liquid into the atomizing tube 100 through the water pipe 400 to be mixed with ozone, so that the gas pump 200 of the present application can be used as a gas source for generating ozone and a power source for mixing ozone with liquid, and further the sterilizing apparatus of the present application has fewer parts, a corresponding structure can be more compact, and reliability is better.

It should be further understood that the atomizing tube 100 according to the present application employs the bernoulli principle, when ozone generated in the plasma generating part 300 is inputted into the atomizing tube 100, the ozone sequentially passes through the first tube part 110, the second tube part 120 and the third tube part 130, and since the inner diameter of the first tube part 110 is gradually reduced and the inner diameter of the second tube part 120 communicating with the first tube part 110 is smaller than that of the first tube part 110, negative pressure can be formed in the second tube part 120 after ozone flows through the first tube part 100 to the second tube part 120, and since the water pipe 400 communicates with the second tube part 120, the negative pressure environment in the second tube part 120 can suck liquid into the second tube part 120 from the water pipe 400, so that the liquid can be mixed with ozone inputted into the second tube part 120 to form ozone water.

In addition, since the gas inputted from the gas pump 200 to the plasma generating part 300 has a certain flow rate, the gas is ionized in the plasma generating part 300 to form ozone, and the ozone enters the atomization tube 100 and still has a certain flow rate, and the liquid is sucked into the second tube part 120 to be mixed with the ozone, and is also impacted by the ozone gas with the flow rate to tear into small water drops, so that the small water drops of the ozone are formed, the small water drops of the ozone are discharged through the spraying opening 131 of the third tube part 130 to form sprayed ozone water, and the atomized ozone water is diffused in the environment to achieve the aim of sterilizing pollutants in the environment. Therefore, the air pump 200 of the present application can also be used as a power source for atomizing ozone water, so that the sterilizing device of the present application can provide a gas source for ozone generated by the plasma generating part 300 and can also provide power for sucking liquid into the atomizing pipe 100 and mixing the liquid with ozone to form atomized ozone water under the condition that only the air pump 200 is provided, and finally, the purpose of simplifying the sterilizing device of the present application is achieved, so that the sterilizing device is conveniently integrated in other equipment.

In the sterilizing apparatus according to the embodiment of the present application, the air pump 200 is sequentially connected with the plasma generating part 300 and the atomizing pipe 100, so that the air pump 200 inputs the gas into the plasma generating part 300 to be ionized by the plasma generating part 300 to form ozone, the air pump 200 can input the ozone into the atomizing pipe 100, and the water pipe 400 is connected with the atomizing pipe 100 so that the liquid can be input into the atomizing pipe 100. Because the inner diameter of the second pipe portion 120 of the atomizing pipe 100 is smaller than the inner diameters of the first pipe portion 110 and the third pipe portion 130, and the inner diameter of the first pipe portion 110 is gradually reduced in the direction from the first pipe portion 110 to the second pipe portion 120, the atomizing pipe 100 has a venturi-like structure, and under the effect of the bernoulli principle, liquid can be sucked into the atomizing pipe 100 through the water pipe 400 to be mixed with ozone to form atomized ozone water, and the atomized ozone water is diffused in the environment to kill pollutants in the environment.

The air pump 200 of the application can be used as an air source for generating ozone, a power source for mixing ozone and liquid and a power source for atomizing ozone water, so that the quantity of components of the sterilizing device of the application is less, the structure is more compact correspondingly, the reliability is better, and the sterilizing device of the application is beneficial to being integrated in other equipment.

In some embodiments, in order to make the atomization effect of the atomized ozone water sprayed by the sterilizing apparatus of the present application more sufficient, the atomizing pipe 100 of the present application may further be provided with a fourth pipe portion 140. The fourth pipe portion 140 is communicated with the third pipe portion 130, specifically, is connected to an end of the third pipe portion 130 opposite to the second pipe portion 120, and correspondingly, the spraying opening 131 is formed at an end of the fourth pipe portion 140 opposite to the third pipe portion 130. In the direction from the third pipe portion 130 to the fourth pipe portion 140, the inner diameter of the fourth pipe portion 140 is set to be gradually reduced so that the fourth pipe portion 140 has a tapered structure, so that the caliber of the spraying port 131 provided at the fourth pipe portion 140 can be set to be relatively small, the fourth pipe portion 140 can serve the purpose of compressing the atomized ozone water, and atomization of the atomized ozone water sprayed through the spraying port 131 of the fourth pipe portion 140 is more sufficient.

The fourth pipe part 140 adopts a tapered structure with gradually reduced inner diameter, so that the inner wall of the fourth pipe part 140 is a smooth transitional inclined plane, and thus, the inner wall of the fourth pipe part 140 has a guiding effect on the atomized ozone water entering the fourth pipe part 140 under the condition that the inner diameter of the fourth pipe part 140 is gradually reduced, so that the atomized ozone water can more efficiently pass through the fourth pipe part 140 and be discharged from the spraying port 131 of the fourth pipe part 140.

In some embodiments, the first pipe portion 110 and the second pipe portion 120 of the present application are in communication, and the first pipe portion 110 and the second pipe portion 120 are in communication with the plasma generating portion 300 and the water pipe 400, respectively, so that there may be a risk that after the liquid in the water pipe 400 is input into the second pipe portion 120, the liquid flows back to the plasma generating portion 300 through the first pipe portion 110, and therefore, the water pipe 400 of the present application may be connected to a portion of the second pipe portion 120 near the third pipe portion 130, so that a connection portion between the water pipe 400 and the second pipe portion 120 is relatively far from the first pipe portion 110, and thus, the liquid input into the second pipe portion 120 by the water pipe 400 may be further far from the first pipe portion 110, thereby achieving a reduction in a risk that the liquid in the second pipe portion 120 flows back into the plasma generating portion 300 through the first pipe portion 110.

In some embodiments, the atomizing tube 100 of the present disclosure may further include a fifth tube portion 150, one end of the fifth tube portion 150 may be disposed in communication with the first tube portion 110, and the other end of the fifth tube portion 150 may be disposed in communication with the plasma generating portion 300. The fifth pipe portion 150 has a uniform inner diameter size in the axial direction thereof, so that the ozone flow can be maintained stable during the process of passing through the fifth pipe portion 150 after ozone generated by the plasma generating portion 300 is inputted into the fifth pipe portion 150, and thus the negative pressure environment in the second pipe portion 120 can be more stable after ozone sequentially passes through the first pipe portion 110, the second pipe portion 120 and the third pipe portion 130.

In some embodiments, in order to make the spraying device of the present application more flexible to use, the flow rate of the gas outputted from the air pump 200 of the present application is adjustable, and the operating voltage introduced into the plasma generating part 300 is also adjustable. When the flow rate of the gas outputted from the gas pump 200 is increased, the flow rate of the gas inputted to the plasma generating part 300 is increased, and more ozone is generated, so that the amount of the ozone gas inputted into the atomizing pipe 100 is also increased, and the concentration of the atomized ozone water formed by the sterilizing apparatus of the present application is increased. In addition, the operating voltage of the plasma generating part 300 is adjustable, so that the intensity of the discharge area of the plasma generating part 300 can be also adjusted, and the plasma generating part 300 can generate more ozone by increasing the operating voltage of the plasma generating part 300, thereby increasing the concentration of the atomized ozone water sprayed by the sterilizing device.

Of course, it should be understood that the flow rate of the air pump 200 and the operating voltage of the plasma generating part 300 can be reduced correspondingly, so that the concentration of the atomized ozone water sprayed by the sterilizing device can be adjusted according to the actual pollution condition of the environment to be sterilized, and the energy consumption of the sterilizing device can be reduced under the condition of fully sterilizing the pollutants in the environment.

Specifically, a flow rate adjusting valve may be disposed between the air pump 200 and the plasma generating part 300 to control the flow rate of the air outputted from the air pump 200, and the plasma generating part 300 may be connected to a voltage-adjustable power source to adjust the operating voltage of the plasma generating part 300.

In addition, it should be further understood that the flow rate of the gas introduced into the atomizing pipe 100 by the air pump 200 is faster, and the flow rate of the liquid introduced into the atomizing pipe 100 by the water pipe 400 is also larger according to the bernoulli principle, so that the flow rate of the atomized ozone water outputted by the sterilizing apparatus of the present application can be adjusted by adjusting the flow rate of the gas outputted by the air pump 200.

In some embodiments, in order that the plasma generating part 300 of the present application may generate plasma and ozone, the plasma generating part 300 of the present application may be configured to include a first electrode 310 and a second electrode 320, wherein the first electrode 310 and the second electrode 320 are disposed opposite to each other, and the first electrode 310 and the second electrode 320 are spaced apart to form a gas path channel 330 between the first electrode 310 and the second electrode 320, and the gas path channel 330 is also a discharge region of the plasma generating part 300. Specifically, any one of the first electrode 310 and the second electrode 320 in the present application may be connected to a power source, the power source may input a voltage to the electrode connected thereto, and the other electrode may be grounded or connected to a voltage lower than an output voltage of the power source, so that a voltage difference may be formed between the first electrode 310 and the second electrode 320, and thus a discharge region may be generated between the first electrode 310 and the second electrode 320. In embodiments of the present application, the second electrode 320 may be connected to a power source and the first electrode 310 may be grounded or connected to a lower voltage relative to the output voltage of the power source.

When the gas outputted from the gas pump 200 passes through the plasma generating part 300, it may pass through the discharge region between the first electrode 310 and the second electrode 320, thereby being ionized in the discharge region between the first electrode 310 and the second electrode 320 to form plasma and ozone, which may then flow into the atomizing tube 100 under the action of the gas pump 200.

In some embodiments, in order to make the ozone generated by the plasma generating part 300 of the present application more sufficient, the second electrode 320 may be provided as a tubular structure, the first electrode 310 is disposed inside the second electrode 320 such that the second electrode 320 encloses the first electrode 310 inside, and a gap is formed between the second electrode 320 and the inner wall and the first electrode 310 such that the gap between the inner wall of the second electrode 320 and the first electrode 310 constitutes the gas path channel 330 and the discharge region of the plasma generating part 300. Since the second electrode 320 encloses the first electrode 310, each portion of the gap between the inner wall of the second motor and the first electrode 310 can form a discharge region of the plasma generating part 300, so that the space of the discharge region of the plasma generating part 300 is relatively larger, and the gas input into the plasma generating part 300 by the gas pump 200 can be ionized more fully, so that the efficiency of generating ozone by the plasma generating part 300 is higher, and the utilization rate of the gas is improved.

In addition, the second electrode 320 is disposed around the first electrode 310, so that the second electrode 320 serves as a housing of the plasma generating part 300, and the space in the second electrode 320 forms the gas path channel 330, so that when the gas output from the gas pump 200 enters the plasma generating part 300, the gas can be concentrated in the second electrode 320 and ionized in the second electrode 320 to generate ozone, and the ozone generated in the second electrode 320 is also concentrated in the second electrode 320 to prevent the ozone from overflowing and diffusing, so that the ozone gas input into the atomizing tube 100 by the plasma generating part 300 is sufficient. The second electrode 320 is used as the housing of the plasma generating unit 300, so that the structure of the plasma generating unit 300 is simplified, the number of parts of the plasma generating unit 300 is reduced, the cost of the plasma generating unit 300 and the sterilizing device is reduced, and the reliability of the plasma generating unit 300 and the sterilizing device is improved.

Specifically, one end of the second electrode 320 of the plasma generating part 300 may be disposed to be in sealing abutment with the gas output pipe of the gas pump 200, and the other end of the second electrode 320 may be disposed to be in sealing abutment with the first pipe part 110 of the atomizing pipe 100, so that ozone may not overflow and leak during the pipe flow.

In some embodiments, in order to enhance the safety of the sterilizing apparatus of the present application, the sterilizing apparatus may further include insulating pipes 340, the number of the insulating pipes 340 may be specifically set to two, and both ends of the plasma generating part 300 may be respectively connected to the two insulating pipes 340 and respectively communicate with the first pipe part 110 of the atomizing pipe 100 and the output end of the air pump 200 through the two insulating pipes 340. The insulating tube 340 is made of an insulating material, and the insulating tube 340 may separate the plasma generating part 300 from the air pump 200 and separate the plasma generating part 300 from the first tube part 110 of the atomizing tube 100. Thus, the electric leakage to the atomizing pipe 100 and the air pump 200 after the plasma generating part 300 is electrified can be prevented, and the short circuit of the plasma generating part 300 can be prevented, thereby achieving the purpose of protecting the sterilizing device of the application.

In some embodiments, in order to make the user more convenient when using the sterilizing device of the present application, the sterilizing device of the present application may further be provided with a water tank 500, the water tank 500 may be loaded with a liquid for mixing with ozone, the water tank 500 is communicated with the second pipe portion 120 of the atomizing pipe 100 through the water pipe 400, when the air pump 200 pushes the ozone gas generated in the plasma generating portion 300 to flow into the atomizing pipe 100, the liquid in the water tank 500 may be pumped into the second pipe portion 120 of the atomizing pipe 100 through the water pipe 400 to mix with ozone, so that the sterilizing device of the present application may generate atomized ozone water without being connected with an external water source during the use, and further the integrated performance of the sterilizing device of the present application is higher, and may be applicable to various environments.
