In the water-free state, the sealing unit 123 and the annular flange 1111 can completely fill the annular groove 1211.

Because the rotating shaft 111 is displaced in the axial direction under the driving action of the water flow, a gap is formed between the connecting member 121 and the rotating shaft 111, and the water flow can flow out of the gap, so that the water flow flowing into the injection unit 112 through the rotating shaft 111 is reduced, the water pressure is reduced, and the rotating speed and the water injection strength of the injection unit 112 and the water injection range of the water flow are affected. Due to the action of the sealing unit 123, the larger the water pressure is, the more the rotating shaft 111 is driven to move towards one side of the injection unit 112, so that the more the annular flanging 1111 tightly presses the sealing unit 123, the better the sealing effect is, and the self-sealing of the sealing unit 123 is realized.

The working principle is as follows: as shown in fig. 2, after water enters the rotating shaft 111 from the adapter 122, the rotating shaft 111 moves towards the direction of the water flow under the action of water pressure, and the annular flange 1111 presses the sealing unit 123, so that the sealing unit 123 seals a gap between the adapter 122 and the connecting member 121, which faces towards the direction of the water flow, and prevents water leakage. The water flow reaches the spherical structure and then is divided to enter different injection units 112, and finally is injected from a plurality of different injection units 112, and under the reaction force of the water flow, the rotary power is provided for the injection units 112, so that the injection units 112 and the rotating shaft 111 integrally rotate along the axial direction of the rotating shaft 111.

When a washing program needs to be executed, the water inlet valve 24 controls water to enter the first water inlet pipe 22, and water is injected into the cylinder assembly 21; when the foam is more in the washing process, the related program controls the water inlet valve 24 to feed water into the second water inlet pipe 23, or the user manually controls the water inlet valve 24 to feed water into the second water inlet pipe 23, so as to feed water into the spray defoaming device 1 and eliminate the foam.

A main pipeline 25 is arranged at the upstream of the water inlet valve 24, and water in the main pipeline 25 branches through the water inlet valve 2 and enters the first water inlet pipe 22 and the second water inlet pipe 23 respectively.

The washing equipment of the invention is provided with two groups of water inlet pipes, one group is used for water inlet to realize the water inlet function in the washing procedure, and the other group is used for defoaming to realize the defoaming function under the condition that the foam amount in the cylinder assembly 21 is too high. Second inlet tube 23 can be equipped with one or more according to the circumstances, because every second inlet tube 23's end all is equipped with sprays fire fighting equipment 1, then can realize diversified defoaming, reduces the foam volume fast, improves defoaming efficiency.

Or, the washing equipment is only provided with a second water inlet pipe 23, and in the washing process, water flows through the second water inlet pipe 23 and is sprayed into the cylinder assembly 21 from the spraying defoaming device 1, and water is injected into the cylinder assembly 21; when the foam is more, the rivers pass through second inlet tube 23 and spout into section of thick bamboo subassembly 21 from spraying defoaming device 1 in, cut the foam, play the effect of defoaming. Consequently, the end of this scheme is equipped with the second inlet tube 23 that sprays fire fighting equipment 1 and can realize the water injection effect, can realize cutting foam again, the effect of defoaming.

The cylinder assembly 21 is composed of two sleeved cylinders, and if the cylinder positioned inside is a non-porous cylinder, the cylinder positioned inside is used for washing and containing water, and the first water inlet pipe 22 and the second water inlet pipe 23 are both communicated and connected with the cylinder positioned inside.

Alternatively, as shown in fig. 6, the cartridge assembly 21 includes an outer cylinder 211 for containing water; an inner drum 212 rotatably disposed in the outer drum 211, communicating with the outer drum 211, for washing laundry; the first water inlet pipe 22 is connected with the outer cylinder 211 and is used for feeding water into the outer cylinder 211; the second water inlet pipe 23 is connected with the outer cylinder 211, and the spraying defoaming device 1 is located inside the outer cylinder 211 and used for eliminating foam overflowing from the inner cylinder 212 to the inner part of the outer cylinder 211. The inner cylinder 212 is provided with a through hole, and the inner cylinder 212 is communicated with the outer cylinder 211 through the through hole.

Further, the spraying defoaming device 1 is arranged close to the opening of the inner cylinder 212, and the spraying part 11 faces the opening of the inner cylinder 212; and/or the spraying defoaming device 1 is arranged between the outer wall of the inner cylinder 212 and the inner wall of the outer cylinder 211.

The washing equipment can be impeller type washing equipment and also can be drum type washing equipment.

As an embodiment, as shown in fig. 6, the washing device is a drum-type washing device, the first water inlet pipe 22 is provided with a water inlet system 26 for containing detergent, and in case that the first water inlet pipe 22 is filled with water, the water flow washes the detergent contained in the water inlet system 26 and then enters the outer tub 211 along with the water flow of the water inlet. The back of the outer cylinder 211 is provided with a driving device 28, and the driving device 28 is connected with the inner cylinder 212 and used for driving the inner cylinder 212 to rotate. A drain 27 is provided at the rear of the lower side of the outer tub 211, and the drain 27 communicates with the outer tub 211 for draining the water in the outer tub 211.

Because the foam in the outer cylinder 211 overflows from the inner cylinder 212, the foam density at the opening of the inner cylinder 212 is higher, and the spraying defoaming device 1 is arranged at the opening of the inner cylinder 212, so that the foam eliminating efficiency can be improved.

Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present invention.
