[0028] Figures 1 to 6, which is a preferred embodiment of the housing structure for a pool cleaning robot provided by the present utility model. As Figures 1 to 6 shown, the housing structure 100 includes a base 10 and an upper shell 20 installed on the base. An inner cavity 30 is formed between the base 10 and the upper shell 20. The inner cavity 30 is divided into a lower cavity 31 inside the base and an upper cavity 32 inside the upper shell for placing the power device 200. The filtering unit 40 is located between the upper cavity 32 and the lower cavity 31. The lower cavity 31 is connected to a water inlet 301, and the upper cavity 32 is connected to a water outlet 302. The water outlet 302 is divided into a front water outlet 3021 and a rear water outlet 3022. The front water outlet 3021 and the rear water outlet 3022 are respectively arranged at the front end and the rear end of the upper shell 20. A flap 50 for micro-adjusting the direction is movably installed in the front water outlet 3021 and / or the rear water outlet 3022. When working, water enters the inner cavity 30 from the water inlet 301. After being filtered by the filtering unit 40, the power device 100 discharges the water in the inner cavity 30 from the front water outlet 3021 or the rear water outlet 3022, generating a reaction force to push the entire robot to move. The flap 50 arranged in the front water outlet 3021 and / or the rear water outlet 3022 adjusts the water outlet angle, thereby adjusting the arc of the walking trajectory of the robot to facilitate the cleaning of the swimming pool.

[0029] As Figure 7 shown, the filtering unit 40 includes a first filter screen layer 41, a second filter screen layer 42, and a third filter screen layer 43 arranged in layers from bottom to top, thus forming a combined filter screen to improve the accuracy. The first filter screen layer 41 and the third filter screen layer 43 are nylon filter screens, and the second filter screen layer 42 is a sponge, which improves the filtering accuracy.

[0030] As Figures 3 to 5 shown, a water outlet channel 61 corresponds to the front water outlet and / or the rear water outlet. A through hole 611 for the flap shaft 51 of the flap 50 to pass through is provided on the side wall of the water outlet channel 61. A washer seat 52 that rotates synchronously with the flap is installed at the bottom of the flap shaft 51. The washer seat 52 is located below the water outlet channel 61. A positioning protrusion 521 is provided on the washer seat 52, and a plurality of positioning grooves 621 that cooperate with the positioning protrusion 521 are provided at the bottom of the water outlet channel 61. In this way, by using the cooperation between the positioning protrusion 521 at the bottom of the flap and the positioning grooves 621 at the bottom of the water outlet channel 61, the angle of the flap 50 can be adjusted as needed, and the water outlet angle can be adjusted, thereby adjusting the arc of the walking trajectory of the robot to facilitate the cleaning of the swimming pool. A protruding ridge 511 is provided on the flap shaft 51, and an opening 522 that cooperates with the protruding ridge 511 is provided on the corresponding washer seat 52. In this way, the washer seat 52 and the flap shaft 51 are locked and fixed with screws. When the flap shaft 51 rotates, the washer seat 52 is synchronously driven to rotate by using the cooperation between the protruding ridge 511 and the opening 522.

[0031] A fairing 60 is installed in the front water outlet and / or the rear water outlet. The fairing 60 forms a water outlet channel 61. A convex seat 62 is provided at the bottom of the fairing. A plurality of positioning grooves 621 are arranged in an arc around the central axis of the through hole 611 at the bottom of the convex seat 62, which ensures that the power device 100 discharges all the water in the inner cavity 30 and also facilitates the installation of the power device 100. In addition, a limiting groove 622 that cooperates with the protruding rib 511 on the paddle shaft 51 is provided on the convex seat 62. The limiting groove 622 communicates with the through hole 611, thereby restricting the rotation angle of the paddle shaft 51 and preventing the positioning protrusion 521 on the spacer seat 52 from falling off the positioning groove 621 arbitrarily.

[0032] As Figure 6 As shown, a floor sweeper 70 is movably installed in the water inlet 301. The floor sweeper 70 includes a floor sweeper frame 71. A floor sweeper brush 72 is installed at the bottom of the floor sweeper frame 71. The floor sweeper frame is provided with a floor sweeper rotating shaft 73. Rotating shaft positioning holes 3011 that cooperate with the floor sweeper rotating shaft are provided on the side walls at both ends of the water inlet 301. The rotating shaft positioning holes 3011 are strip-shaped. When the floor sweeper swings back and forth on the ground, due to the strip-shaped rotating shaft positioning holes 3011, the floor sweeper rotating shaft 73 on the floor sweeper frame 71 can move up and down, so that the depth of contact between the floor sweeper and the ground remains consistent. Convex shoulders 711 are formed at both ends of the floor sweeper frame 71. Step seats 3012 are formed at both ends of the water inlet. A limiting arc surface 3013 that cooperates with the convex shoulders 711 is formed on the bottom surface of the step seat 3012. When the robot moves forward and backward, it drives the floor sweeper to swing. The convex shoulders 711 of the floor sweeper move back and forth correspondingly along the limiting arc surface 3013 on the base 10. At the same time, the floor sweeper rotating shaft 73 floats up and down correspondingly in the rotating shaft positioning holes 3011 of the bottom case, so as to realize the floor sweeper to clean at the same depth at different angles and on the ground, which is convenient for cleaning the swimming pool.
