[0033] When the water hose 20 is wound, it needs to pass through the passing channel 43 first and then be arranged around the winding rod structure 32. When the water hose 20 passes through the passing channel 43, it is limited to move along the rotation axis of the rotating disc 31, that is, it is limited to move along the width direction of itself, so that each part of the water hose 20 can be aligned with the winding rod structure 32, and the wound water hose 20 is arranged neatly around the winding rod structure 32, reducing or even avoiding the situation that part of the water hose 20 protrudes from the water hose reel along the width direction of itself.

[0034] In some specific embodiments, referring to Figures 1 to 4 The limiting structure 4 is arranged below the side of the winding rod structure 32, and the limiting structure 4 comprises two limiting rods 42 and two limiting columns 41, the two ends of the limiting rod 42 are connected to the two limiting columns 41 respectively, the two limiting rods 42 are arranged in the up-down direction and extend along the rotation axis of the rotating disc 31, and the two limiting rods 42 and the two limiting columns 41 enclose the passing channel 43.

[0035] Arranging the limiting structure 4 below the side of the winding rod structure 32 makes the resistance of the water hose 20 to the limiting structure 4 smaller during winding, especially the resistance to the limiting rod 42, which is beneficial to make the winding more smooth and reduce the burden of the driving device 2. The two ends of the limiting rod 42 are connected to the two limiting columns 41 respectively and extend along the rotation axis of the rotating disc 31, that is, the two limiting columns 41 are arranged along the rotation axis of the rotating disc 31, and when winding, the water hose 20 passes through the passing channel 43 and is arranged around the winding rod structure 32, the direction of the rotation axis of the rotating disc 31 is the width direction of the water hose 20, and the two limiting columns 41 can limit the movement of the water hose 20 along the width direction of itself during winding, so that the wound water hose 20 can be arranged neatly around the winding rod structure 32.

When the opening and closing end 4214 is to be removed, the first limiting rod 421 is rotated by loosening the clamping screw 4122 to release the opening and closing end 4214 of the first limiting rod 421, and then the hose 20 is put in or taken out; when the opening and closing end 4214 is to be fixed, the opening and closing end 4214 of the first limiting rod 421 is clamped in the bearing groove 4121 by tightening the clamping screw 4122, forming the hose passing channel 43.
