In the present embodiment, the plurality of first shower holes 110 are formed with first unit shower holes 111 on the top wall 141, second unit shower holes 112 on the oblique peripheral wall 142, and third unit shower holes 113 on the arc-shaped transition peripheral wall 143.
In the present embodiment, three pairs of first spray hole groups are provided in the first unit spray holes 111 of the top wall 141 as shown in fig. 3, which are arranged in central symmetry with the spray cover 140. Each pair of the first spray hole groups provided at the top wall 141 are symmetrically provided along the same diameter with the center of the spray cover 140 as a symmetry center. In this embodiment, the second spray holes 120 are symmetrically provided with three pairs of second spray hole groups with the center of the spray cover 140 as the center of symmetry.

Thereby redirecting the reaction force F of the momentum of the water flow. A reaction force F acts on the shower cover 140.
A pair of first groups of spray holes are provided in the top wall 141 or the sloped peripheral wall 142 or the curved transitional peripheral wall 143 of the spray cap, wherein a first group of spray holes is provided in a first slope that causes a reaction force F of an impulsive force of water flowing out of the spray holes to generate a first tangential force on the spray cap perpendicular to the axis of rotation of the spray cap.
The other of the pair of first spray hole groups is arranged in a second oblique direction, and the second oblique direction enables the reaction force F of the impulsive force of the water flow flowing out of the spray holes to generate a second tangential acting force vertical to the rotation axis of the spray cover on the spray cover.
The first tangential acting force and the second tangential acting force are opposite, so that a rotating moment is generated on the spraying cover, and the spraying cover can rotate relative to the shell.
It should be further noted that the first oblique arrangement and the second oblique arrangement indicate that the opening directions of the first spray holes in one first spray hole group of the pair of first spray hole groups are opposite to the opening directions of the first spray holes in the other first spray hole group, but all the first spray holes in the pair of first spray hole groups and the cover surface of the spray cover 140 where each first spray hole is located have the same included angle, and the included angle is 45 °. Therefore, the first tangential acting force and the second tangential acting force are opposite, a rotating moment is generated on the spray cover, and the spray cover can rotate along the omega direction relative to the shell.
As shown in fig. 4, the first tangential force and the second tangential force are opposite and symmetrical with respect to the central axis of the spray cap of the present embodiment, so as to make the spray cap 140 rotate more smoothly and have less resistance, it is preferable that: the central axis of the spray cover is used as a symmetry center, a pair of first spray hole groups which are symmetrically arranged should have the same hole structure, the same number of first spray holes 110 and the same hole arrangement mode, the opening direction of each first spray hole and the cover surface of the spray cover 140 where each first spray hole is located all have the same included angle, and the included angle is 45 degrees.
At least one of the rotating showerheads 100 is fixedly or rotatably disposed on a top wall 141 and/or a peripheral wall 240 of a washing chamber formed by the washing chamber.
The rotary shower head 100 in this embodiment is fixedly disposed on a peripheral wall 240 of a washing chamber 200 as shown in fig. 5. The washing chamber 200 is provided with a washing chamber cover 230, a washing chamber inlet pipe 210, a washing chamber inlet 211, a washing chamber drain pipe 220, and a washing chamber drain port 221.
An included angle of β is formed between the rotation axis of the spray cover of the rotary spray head 100 and the peripheral wall 240, when water is sprayed out from the rotary spray head 100, the water sprayed out from the second unit spray holes 112 and the third unit spray holes 113 sprays the peripheral wall 240 of the washing chamber, the spray areas are A and C, the water sprayed out from the first unit spray holes 111 and the second unit spray holes 120 sprays the bottom of the washing chamber formed by the washing chamber, and the spray area is B.
Further, when the width of the washing chamber is a and the spray height is b, β is tan (b/2a) °.
When the rotary spray head 100 performs rotary spraying, the first spray holes 110 mainly provide a rotary acting force for the rotation of the spray cover 140, and the washing water sprayed from the first spray holes 110 arranged on the inclined peripheral wall 142 and the arc-shaped transitional peripheral wall 143 of the spray cover 140 generally acts on the peripheral wall 240 of the washing cavity formed by the washing chamber, so as to provide a spray cleaning effect for the washing chamber. The washing water sprayed from the first spray holes 110 and the second spray holes 120 formed on the top wall 141 directly acts on the laundry to spray and wash the laundry. The second spraying holes 120 are straight circular holes formed in the top wall 141, but due to the continuous rotation action of the rotary spraying head 100 during spraying, the washing water sprayed from the second spraying holes 120 has a gravitational acceleration along the direction of gravity, and simultaneously has a speed during rotation of the rotary spraying head 100, so that the washing water sprayed from the second spraying holes 120 is sprayed onto the washed objects in a spiral shape. The beneficial effects are that: the spraying action area of the second spraying holes 120 on the washings is increased, the spraying action is softer than that of direct-current spraying, the damage to the washings is reduced, and the washings are better cared under the condition of cleaning the washings.
In another implementation scenario of the present embodiment, a water inlet channel dedicated to supply the second spraying holes 120 is disposed in the water inlet 160, so that the water flow sprayed from the second spraying holes 120 in the rotary spraying process of the rotary spraying head 100 is direct current and is not affected by the rotation of the spraying cover 140. The water flow sprayed from the second spraying holes 120 directly acts on the laundry to wash the special stained parts of the laundry in a targeted manner.
The water inlet pressure of the water inlet 160 in the rotary shower head 100 can be adjusted, the rotary shower head 100 rotates at a lower speed when the water pressure is medium, and at this time, the water flow in the inclined peripheral wall 142, the arc-shaped transitional peripheral wall 143 and the inclined holes in the top wall 141 cannot be thrown out due to excessive centrifugal force, and the water flow is mainly sprayed on the washed objects. When the water pressure is higher, the rotating speed is higher, the centrifugal force is large, the water flow of the inclined peripheral wall 142, the arc-shaped transition peripheral wall 143 and the inclined holes of the top wall 141 can be thrown out under the action of the centrifugal force, the spraying area is enlarged, and meanwhile, the wall of the washing chamber can be cleaned.
Further, the rotation of the spray cap 140 is controlled within a certain range by the connection between the housing 130 and the spray cap 140, which is required to allow the spray cap 140 to perform the rotation movement independently of the housing 130. Therefore, the shower cover 140 is connected with the housing 130 by a bearing. On the other hand, the housing 130 mainly receives pressure from water flow, i.e., longitudinal force, and therefore a thrust ball bearing is used in the present embodiment.
