[0007] Preferably, positioning grooves are provided on the lower surface of the robot body and on both sides of the dirt suction head. The number of the positioning grooves is five, and the five positioning grooves are evenly distributed laterally on the lower surface of the robot body.

[0008] Preferably, both side surfaces of the suction head are provided with sockets, and the inner lower surface of the socket is provided with a limiting sliding groove in the middle.

[0009] Preferably, a limiting slide bar is fixedly mounted on the lower surface of the opening and closing plate, a sleeve is fixedly mounted on the rear surface of the opening and closing plate, the opening and closing plate is movably embedded in the socket, and the limiting slide bar is embedded in the limiting slide groove.

[0010] Preferably, the upper end of the positioning rod passes through the sleeve and is embedded in the positioning groove, a stop ring is fixedly sleeved on the surface of the positioning rod inside the sleeve, and a spring is sleeved on the surface of the positioning rod inside the sleeve and below the stop ring.

[0011] Preferably, the sum of the widths of the opening and closing plates on both sides inside the sewage suction head is greater than the outer diameter of the sewage suction head.

[0012] Preferably, the upper end of the spring is fixed to the stop ring, and the lower end of the spring is fixed to the inner lower surface of the sleeve.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, by arranging the robot body, the sewage suction head, the opening and closing plate and the positioning rod to cooperate with each other, the positioning rod is pulled downward so that the upper end of the positioning rod is drawn out from the positioning groove of the robot body, and then the opening and closing plate is moved. When the opening and closing plate moves to the required position, the external force pulling the positioning rod is released. At this time, the spring will push the stop ring upward so that the upper end of the positioning rod is embedded in the positioning groove of the robot body. In this way, the opening size of the sewage suction head can be adjusted. When the sewage suction head is not in use, the sewage suction head can be closed by using the opening and closing plate, thereby preventing some unnecessary foreign matter from passing through the sewage suction head and entering the interior of the robot body.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4The swimming pool robot shown has an adjustable sewage suction head, comprising a robot body 1 and a sewage suction head 2. The sewage suction head 2 is fixedly installed on the lower surface of the robot body 1 near the front end and the rear end. An opening and closing plate 3 is movably embedded on both sides of the interior of the sewage suction head 2. A positioning rod 4 is movably embedded on the lower surface of the opening and closing plate 3 near the rear end.

[0022] Positioning grooves 101 are provided on the lower surface of the robot body 1 and on both sides of the suction head 2. There are five positioning grooves 101, which are evenly distributed on the lower surface of the robot body 1. The cooperation between the positioning grooves 101 and the positioning rods 4 can position the opening and closing plate 3. Sockets 201 are provided on the two side surfaces of the suction head 2. A limiting slide groove 202 is provided on the inner lower surface of the socket 201 and located in the middle. The cooperation between the limiting slide groove 202 and the limiting slide bar 301 can assist the smooth movement of the opening and closing plate 3. The limiting slide bar 301 is fixedly installed on the lower surface of the opening and closing plate 3, and the sleeve 302 is fixedly installed on the rear surface of the opening and closing plate 3. The opening and closing plate 3 is movably embedded in the socket 201, and the limiting slide bar 301 is embedded in the limiting slide groove 202; the upper end of the positioning rod 4 passes through the sleeve 302 and is embedded in the positioning groove 101, and a stop ring 401 is fixedly sleeved on the surface of the positioning rod 4 located inside the sleeve 302, and a spring 402 is sleeved on the surface of the positioning rod 4 located inside the sleeve 302 and below the stop ring 401, and the spring 402 has an upward thrust on the stop ring 401; the sum of the widths of the opening and closing plates 3 on both sides of the interior of the suction head 2 is greater than the outer diameter of the suction head 2; the upper end of the spring 402 is fixed to the stop ring 401, and the lower end of the spring 402 is fixed to the inner lower surface of the sleeve 302.

[0023] It should be noted that the utility model is an adjustable sewage suction head of a swimming pool robot. When in use, the positioning rod 4 is pulled downward so that the upper end of the positioning rod 4 is pulled out from the positioning groove 101 of the robot body 1, and then the opening and closing plate 3 is moved. When the opening and closing plate 3 moves to the required position, the external force pulling the positioning rod 4 is released. At this time, the spring 402 will push the stop ring 401 upward so that the upper end of the positioning rod 4 is embedded in the positioning groove 101 of the robot body 1. In this way, the opening size of the sewage suction head 2 can be adjusted. When the sewage suction head 2 is not in use, the sewage suction head 2 can be closed using the opening and closing plate 3 to prevent some unnecessary foreign matter from passing through the sewage suction head 2 and entering the interior of the robot body 1.
