As a preferred solution, the bearing body 4 adopts a double-sided sealed deep groove ball bearing, and the material thereof can be selected from 304 stainless steel. The bottom end of the rotating shaft 2 forms a head 21 located below the bearing body 4. The head 21 can be understood as an annular body, the outer diameter of the head 21 is greater than the outer diameter of the rotating shaft 2, a sealing gasket 3 is arranged between the top end surface of the head 21 and the bottom end surface of the bearing body 4, the sealing gasket 3 is sleeved on the outer circumferential side of the rotating shaft 2 and located inside the first through hole 11. Optionally, the sealing gasket 3 can be made of polytetrafluoroethylene, and the sealing gasket 3 is arranged in a concave shape, so that the sealing gasket 3 can be buckled on the bearing body 4, reducing the amount of water entering and exiting through the gap of the bearing body 4, and ensuring the stable operation of the nozzle. It should be noted that the bearing body 4 and the bearing seat 1 are in an interference fit, and the bearing body 4 and the rotating shaft 2 are in an interference fit. Through the interference fit between the bearing body 4 and the bearing seat 1, the rotation of the rotating shaft 2 relative to the bearing seat 1 is more smooth and smooth, and the power output is more smooth.

[0029] In this embodiment, the top end of the rotating shaft 2 penetrates the top surface of the bearing seat 1, and the top end of the rotating shaft 2 is fixedly installed with a connecting seat 5. The connecting seat 5 is a hollow structure, the connecting seat 5 is provided with a third through hole 53 in the axial direction, the top end of the rotating shaft 2 penetrates the third through hole 53, and the cooperation between the rotating shaft 2 and the third through hole 53 is an interference fit or a clearance fit. In order to improve the connection strength between the connecting seat 5 and the connecting shaft, a threaded hole is formed in the outer circumferential side of the connecting seat 5 in the radial direction of the connecting seat 5, the threaded hole is in communication with the third through hole 53, and a fastening screw 7 is threadedly connected in the threaded hole. The connection strength between the rotating shaft 2 and the connecting seat 5 can be adjusted by the fastening screw.

[0030] Leave Figures 1 to 2 The top of the connecting seat 5 is fixedly connected with a nozzle body 6. Optionally, the top end surface of the nozzle body 6 is a smooth spherical surface, and the head 21 of the nozzle body 6 is smooth, which can avoid scratching the pet or person by the nozzle and improve safety. The bottom surface of the nozzle body 6 is provided with a blind hole 61, and the top of the connecting seat 5 penetrates into the blind hole 61. The top end of the connecting seat 5 extends out of an extension 51 towards the blind hole 61, the extension 51 is inserted into the blind hole 61, and the extension 51 is sealingly and fixedly connected with the blind hole 61. Optionally, see Figure 3, the extension part 51 extends outwardly to a sealing part 52 abutting against the hole wall of the blind hole 61, the top end surface of the sealing part 52 forms a tapered flow guide surface, and a gap is left between the top end surface of the extension part 51 and the hole bottom of the blind hole 61. Optionally, the flow guide surface can be understood as an inclined surface or inclined angle formed at the edge of the sealing part 52, and the specific taper can be selected as 150 degrees. The flow guide surface can make the rotating water droplets be centrifugally atomized under the action of centrifugal force, and all water droplets participate in cleaning.

[0031] See Figure 4 and Figure 5 Two water outlets 62 are formed on the outer peripheral side surface of the nozzle body 6 and communicated with the blind hole 61. The water outlet 62 can be understood as a water outlet channel formed in the nozzle body 6, and the water outlet channel is arranged at a certain angle relative to the axial direction of the nozzle body 6.

The problem that the previous nozzle cannot be applied to small flow drainage is solved, the applicability is improved, the water resources are saved, and the problem of poor applicability is solved. In combination with the water outlets 62 at different positions, fine water droplets can be sprayed out in the form of 100-120 water lines with a taper of 150 degrees. When the water lines contact the hair or object after being sprayed out, the water droplets are broken into fine particles, which can scatter the pet hair or human hair, thereby achieving the cleaning effect. In addition, by arranging the bearing body 4, the rotating shaft 2 is not easy to be stuck, the reasonable design layout makes the nozzle have good wear resistance, long service life, and no eccentric wear phenomenon, and the water droplets on the cleaning surface are uniformly covered and have uniform diameters.
