As shown in fig. 4, the fluid channel 200 of the disclosed embodiment includes, for example, a first channel segment, a second channel segment, and a third channel segment 200C. A third channel segment 200C is shown in fig. 4, the third channel segment 200C being disposed, for example, proximate the second end 120.

In addition, the second end 120 is provided with a groove 121, the third channel segment 200C for example extends through the groove 121, and the outlet 230 is provided in the groove 121. The guide member 300 covers the groove 121, for example, and a predetermined gap 400 is provided between the guide member 300 and the surface of the second end 120, the predetermined gap 400 communicating with the groove 121. The fluid from the outlet 230 flows through the groove 121 and then flows out along the predetermined gap 400.

As shown in fig. 4, the first channel section and the second channel section are located, for example, in the reference plane P. The third channel segment 200C is for example arranged obliquely with respect to the reference plane P. The inclination angle is, for example, greater than 0 ° and less than 90 °, so that the fluid from the outlet 230 is blown to the guide member 300 and guided to the preset gap 400 via the guide member 300.

The cleaning device was cut by the cross-section O to obtain a cross-section shown in fig. 5. The partial structure Q of fig. 4 is shown below in fig. 6.

As shown in fig. 5, the fluid channel 200 includes, for example, a first channel segment 200A, a second channel segment 200B, and a third channel segment 200C.

The first channel section 200A, for example, includes a first end at which the first inlet 210 is disposed and a second end. The second channel segment 200B, for example, includes a third end and a fourth end, with the second inlet 220 disposed at the third end. The third channel segment 200C for example comprises a fifth end and a sixth end, the fifth end being connected to the second end and the fourth end, the outlet 230 being provided at the sixth end.

For the first channel segment 200A, the direction pointing from the second end to the first end is the first direction B. For the second channel segment 200B, the direction pointing from the fourth end to the third end is the second direction C. The angle between the first direction B and the second direction C is for example greater than 0 ° and less than 90 °.

The included angle is set to be larger than 0 degrees, so that the air flow and the liquid flow are fully mixed, and the liquid flow is atomized under the action of the air flow, and then the cleaning effect is improved. In addition, the included angle between the first direction B and the second direction C is smaller than 90 degrees, and the phenomenon that the flow speed is reduced due to the fact that the acting force of different fluids is too large is avoided. It can be seen that the included angle between the first direction B and the second direction C is larger than 0 degree and smaller than 90 degrees, so that the fluid can be fully mixed, the speed of the fluid can be guaranteed, and the cleaning effect is improved.

In an embodiment, the angle between the first direction B and the second direction C is, for example, greater than 20 ° and less than 50 °. The included angle is more than 20 degrees and less than 50 degrees, so that the mixing degree of the fluid can be improved, and the speed of the fluid is ensured to a large extent.

As shown in fig. 5, in an embodiment, the cleaning device may further include a first one-way valve 500. The first check valve 500 is disposed, for example, within the first passage section 200A.

The first channel section 200A includes a first end at which the first inlet 210 is disposed and a second end. 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.

After passing through the groove, the fluid from the outlet is guided to the predetermined gap 400 by the flow guide member 300 and flows out along the predetermined gap 400.

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.
