In some embodiments, as shown in fig. 3 and 4, the spraying device includes an impeller 10, and correspondingly, a second cavity is provided at the bottom of the outer cylinder 4, the impeller 10 is provided in the second cavity, the impeller 10 drives water in the second cavity to move by rotating, the water is gathered near the inner wall of the second cavity during the rotation of the impeller 10, and as the water amount increases, the pressure of the water increases, and finally the water is sprayed into the inner part of the inner cylinder 6 through the hollow part. Impeller 10 can dismantle with pivot 7 and be connected, specifically, the periphery of pivot 7 is located to impeller 10 cover to with the 7 key-type connections of pivot, use the key-type connection, both conveniently dismantle and the installation impeller 10, when again preventing pivot 7 from rotating, impeller 10 and pivot 7 take place relative rotation. The vanes of the impeller 10 are vertical flat-plate vanes, and the number of the vanes in this embodiment is eight, but the vanes are not limited to eight, and four, five, six, or the like may be provided. The impeller 10 is able to cause water to be sprayed into the interior of the inner barrel 6 whether the drive means 8 is rotating in a forward or reverse direction.
Preferably, the width of the end of the blade close to the rotating shaft 7 is larger than that of the end far from the rotating shaft 7, so that when the impeller 10 rotates, more water can enter the second cavity, and the spraying effect is improved.
Preferably, in the case that the bottom of the outer tub 4 is provided with a second cavity, the water inlet 14 and the water outlet 15 of the outer tub 4 can be provided at the bottom of the second cavity, and since the second cavity is located at a lower position, the water outlet 15 is provided at the bottom of the second cavity to facilitate the discharge of all water inside the outer tub 4.
In order to improve the water spraying efficiency of the spraying device, the cross section of the second cavity in the horizontal direction is set to be circular, and the diameter of the second cavity in the horizontal direction is slightly larger than the outer diameter of the impeller 10. When the driving device 8 drives the rotating shaft 7 to rotate, the impeller 10 also rotates along with the rotating shaft 7, water near the rotating shaft 7 moves downwards, the impeller 10 pushes the water to be near the side wall of the second cavity, the water near the side wall moves upwards due to pressure accumulation, and a spraying effect is formed after the water passes through the hollow part. The side wall of the second cavity plays a role in guiding water flow, the smaller the gap between the side wall of the second cavity and the impeller 10 is, the higher the water spraying efficiency of the spraying device is, and meanwhile, the smaller the gap is, the higher the collision probability between the impeller 10 and the side wall of the second cavity is when the impeller rotates, so that a person skilled in the art can determine the optimal value of the gap size according to an experimental result in specific implementation. The impeller 10 is arranged in the second cavity, so that the spraying efficiency of the spraying device is improved.
