The first one-way valve 500 is used, for example, to direct fluid from the first end to the second end and to prevent fluid from flowing from the second end to the first end. That is, fluid from the first inlet 210 is not restricted from flowing from the first end to the second end, but fluid is restricted from flowing from the second end to the first end.
In another embodiment, the cleaning apparatus may further include a second one-way valve 600. The second check valve 600 is disposed, for example, within the second channel segment 200B.
The second channel segment 200B includes a third end and a fourth end, with the second inlet 220 disposed at the third end. The second check valve 600 is used, for example, to direct fluid from the third end to the fourth end and to prevent fluid from flowing from the fourth end to the third end. That is, fluid from the second inlet port 220 is not restricted from flowing from the third end to the fourth end, but fluid is restricted from flowing from the fourth end to the third end.
In one embodiment, a one-way valve may be provided in either of the first channel section 200A and the second channel section 200B, the channel section of the one-way valve being arranged to receive the flow of liquid to avoid backflow of the flow of liquid. The probability of the gas stream flowing back in the channel section is small since the pressure of the gas stream is usually large, while the probability of the liquid stream flowing back in the channel section is large since the pressure of the liquid stream is usually small.
In another embodiment, a one-way valve may be provided in both the first channel segment 200A and the second channel segment 200B. For example, a first check valve 500 is disposed within the first channel segment 200A and a second check valve 600 is disposed within the second channel segment 200B.
The first check valve 500 and the second check valve 600 may be composed of, for example, a packing, a valve body, a spring, or the like, or may be composed of a spring and an elastic valve body. The first check valve 500 and the second check valve 600 are used to realize one-way conduction. The embodiment of the present disclosure does not limit the specific structure of the first check valve 500 and the second check valve 600, and those skilled in the art can set the specific structure according to the actual application.

According to the embodiment of the disclosure, the fluid flows to the preset gap from the fluid channel, the area through which the fluid passes is narrower and narrower, so that the fluid is accelerated when flowing out of the preset gap, and when cleaning an object, the cleaning efficiency is higher and the cleaning effect is better when the flowing-out high-speed fluid is used for cleaning the object.
The cleaning device of the embodiment of the disclosure can realize cleaning with the liquid stream alone, can realize cleaning with the air current alone again, can also realize liquid stream (cleaning solution) quick atomization with liquid stream and air current cooperation simultaneously, and the liquid stream after the atomizing is fine and close and spray evenly, improves clean effect. In addition, the cleaning device is dense in structural arrangement, high in integration level, smaller in occupied space and convenient to arrange and install. When cleaning is carried out, a small amount of liquid flow can be matched with the air flow, so that the liquid flow is atomized, and the liquid flow (cleaning liquid) is consumed less during cleaning, thereby reducing the cleaning cost.
