[0002] During the maintenance of aircraft components, it is often necessary to clean them to remove contaminants such as grease, dust, and carbon deposits from their surfaces, as well as reduce corrosion and wear, extend their service life, and ensure flight safety.

[0003] Currently, most aircraft components are cleaned using tap water, but this method has the following drawbacks:

[0004] 1. When cleaning aviation kerosene and other adhering contaminants, tap water has poor dissolving ability, so the cleaning effect is not good, it is not easy to remove the contaminants, and it also wastes water resources.

[0005] Second: When cleaning with tap water, a certain pressure needs to be applied to the water in order to rinse the aircraft parts. However, when the water pressure is too high, it is not easy to operate and there is an operational risk. Utility Model Content

[0006] In view of the shortcomings of the prior art, the present invention provides a micro-nano bubble generator and a cleaning device. The technical problem to be solved is that existing aerospace components have poor cleaning effect and are difficult to operate when rinsed with tap water.

[0007] To solve the above technical problems, in the first aspect, this utility model provides the following technical solution: a micro-nano bubble generator, including a body, the body having a flow channel, the flow channel being divided into an input flow channel and a Venturi flow channel along the conveying direction, the diameter of the input flow channel gradually increasing along the conveying direction, and bubble shearing plates being provided in the input flow channel and the Venturi flow channel respectively.

[0009] In one embodiment of the first aspect, mounting threads are respectively provided on the outer side walls at both ends of the body.

[0010] Secondly, this utility model also provides a cleaning device, including the aforementioned micro-nano bubble generator, and further including a water delivery device, an oxygen delivery device, and an output pipe. The water delivery device and the oxygen delivery device respectively supply water and oxygen to the inlet of the flow channel, and the outlet of the flow channel is connected to the output pipe.

[0011] In one embodiment of the second aspect, the oxygen delivery device also delivers oxygen to the output pipe.

[0012] In one embodiment of the second aspect, the oxygen delivery device includes an oxygen generator, a delivery pump, a flow meter, a first pressure gauge, and a one-way valve connected in sequence via an oxygen delivery pipe. The outlet of the one-way valve delivers oxygen to the inlet and outlet pipes of the flow channel via an oxygen connection pipe.

[0013] In one embodiment of the second aspect, the outlet of the delivery pump is also connected to a pressure regulating pipeline, which is equipped with a back pressure regulating valve and a solenoid valve.

[0014] In one embodiment of the second aspect, the water delivery device includes a water pump connected to the inlet of the flow channel via a water delivery pipe, the water delivery pipe being equipped with a second pressure gauge.

In addition, by setting the channel diameter on the bubble shear plate, bubbles of different diameters can be generated, thus making it suitable for a variety of applications. Finally, the entire structure is simple and does not require complex components or precious metals. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Example 1

[0024] like Figure 1-3 As shown, the micro / nano bubble generator provided in this embodiment includes a body 1. The body 1 is provided with a flow channel, which is divided into an input flow channel 100 and a Venturi flow channel along the conveying direction. The Venturi flow channel is divided into three sections, which are an input tapering end 110, a middle end 111, and an output expanding end 112 along the conveying direction. The diameter of the input flow channel 100 gradually increases along the conveying direction. A bubble shearing plate 101 is provided in the input flow channel 100 and the Venturi flow channel, respectively.

[0025] In practical use, the bubble generator in this embodiment can convert tap water into micro-nano bubbles. When these micro-nano bubbles are sprayed onto the surface of the aircraft through the spray device, they can effectively adsorb various stains, improving the cleaning effect while using less water. Secondly, compared to cleaning directly with tap water, it requires less water pressure, reducing cleaning risks. Furthermore, by setting the channel diameter on the bubble shear plate 101, bubbles of different diameters can be generated, making it suitable for various applications. Finally, the entire structure is simple, requiring no complex components or precious metals.

[0026] Specifically, in this embodiment, the inlet of the Venturi channel is provided with an input bubble shear plate 113, and the middle end 111 of the Venturi channel is provided with at least one intermediate bubble shear plate 114. For example, Figure 3 The middle end 111 of the Venturi channel is provided with two intermediate bubble shearing plates 114, and the output port of the Venturi channel is provided with an output bubble shearing plate 115.

[0027] In this embodiment, Figure 3 The channel dimensions of the bubble shear plate in the code are as follows:

[0028] The channel aperture of the bubble shear plate 101 in the input channel 100 is 2 μm, the channel aperture of the input bubble shear plate 113 is 0.5 μm, the channel aperture of the middle bubble shear plate 114 on the left side of the middle end 111 of the Venturi channel is 0.2 μm, the channel aperture of the middle bubble shear plate 114 on the right side of the middle end 111 of the Venturi channel is 80 nm, and the channel aperture of the output bubble shear plate 115 is 60 nm.

[0029] In addition, the bubble shearing plates in this embodiment are all ceramic sheets.

[0030] In this embodiment, in order to facilitate installation, mounting threads 104 are respectively provided on the outer side walls at both ends of the main body 1.

[0031] Example 2

[0032] like Figure 4 As shown, this embodiment provides a cleaning device, including the micro-nano bubble generator in Embodiment 1, as well as a water delivery device 2, an oxygen delivery device 3 and an output pipe. The water delivery device 2 and the oxygen delivery device 3 respectively supply water and oxygen to the inlet 102 of the flow channel, and the outlet 103 of the flow channel is connected to the output pipe.

[0033] It should be noted that, although attached Figure 4 The output tube is not labeled, but for those skilled in the art, the connection between the flow channel and the output tube is a well-known technique in the field.

[0034] In actual use, by supplying water and oxygen to the inlet 102 of the flow channel, the water and oxygen pass through the bubble shear plate in the flow channel, making the water rich in oxygen. This results in the bubbles ejected from the bubble generator having strong cleaning ability and good cleaning effect.

[0035] In actual use, the oxygen content in the bubbles ejected from the bubble generator may be low, so the oxygen delivery device 2 can also deliver oxygen to the output pipe.

[0036] Specifically, in this embodiment, as Figure 4 As shown, the oxygen delivery device 1 includes an oxygen generator 200, a delivery pump 201, a flow meter 202, a first pressure gauge 203 and a one-way valve 204 connected in sequence through an oxygen delivery pipe. The outlet of the one-way valve 204 delivers oxygen to the inlet 102 of the flow channel and the outlet pipe through the oxygen connection pipe.

[0037] It should be noted that, although attached Figure 4 The oxygen delivery pipe and oxygen connection pipe are not labeled, but for those skilled in the art, connecting the components of the oxygen delivery device 1 through the oxygen output pipe and connecting the oxygen output device with the flow channel and output pipe through the oxygen connection pipe are common practices in the field.

[0038] In this embodiment, the first pressure gauge 203 is a mechanical pressure gauge used to check the output oxygen pressure and display it on-site for easy viewing, while the flow meter 202 is used to detect the oxygen flow rate.

[0039] In this embodiment, in order to adjust the pressure of the delivered oxygen, the outlet of the delivery pump 201 is also connected to a pressure regulating pipeline, which is equipped with a back pressure regulating valve 205 and a solenoid valve 206.

[0040] In this embodiment, as Figure 4 As shown, the water conveying device 3 includes a water pump 300, which is connected to the inlet 102 of the flow channel through a water conveying pipe. A second pressure gauge 301 is provided on the water conveying pipe.

[0041] The water pump 300 can be a variable frequency water pump, which can adjust the pressure of the output water to meet different cleaning needs.

[0042] In addition, in this embodiment, the outlet of the water pump 300 is also connected to a water discharge pipeline, and a discharge valve 302 is provided on the water discharge pipeline. Water can be discharged by opening the discharge valve 302.

[0043] exist Figure 4 In addition, this utility model also includes a control unit 4, which is electrically connected to the water pump 300, oxygen generator 200, delivery pump 201 and solenoid valve 206 respectively, and is used to control the on and off of the water pump 300, oxygen generator 200, delivery pump 201 and solenoid valve 206 and their operating frequency. The control unit 4 also detects the water pressure in the water output pipe through the pressure sensor 303 and detects the dissolved oxygen rate of the water in the water output pipe through the oxygen solubility sensor 5.

[0044] In actual use, when the control unit 4 detects that the dissolved oxygen rate of the water in the water output pipe is lower than the target value through the oxygen dissolution rate sensor 5, the control unit 4 can increase the oxygen delivery by controlling the operating speed of the delivery pump 201, thereby increasing the dissolved oxygen rate of the water.

[0045] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
