It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in fig. 1-3, the present invention provides an inclined plane air suction structure of a rolling brush seat, which includes a rolling brush 10 and a shell with an opening on one side, wherein the rolling brush 10 is embedded in the shell, the shell is provided with a water suction inlet arranged opposite to the rolling brush 10, the shell includes an upper shell 11 and a lower shell 12 which are connected with each other, the water suction inlet is arranged on the lower shell 12, and the lower shell 12 is integrally arranged in an inclined manner towards the water suction inlet;

when the round brush seat during operation, because debris and the sewage that round brush 10 adsorbed from ground can follow round brush 10 at first and rotate to lower casing 12 in, just secondly can be adsorbed by the water inlet that draws water and walk, lower casing 12 is general as in figure 1 with the clearance between the round brush seat, so when debris fall into parallel portion 5, because parallel portion 5 and water inlet 3 are in on the same horizontal plane, and the clearance undersize, the debris that fall into parallel portion 5 block round brush 10 easily, and only have the orientation slope of concave part 4 to water inlet 3 in figure 1, only the interior debris of concave part 4 can be adsorbed by water inlet 3, nevertheless the whole volume undersize of concave part 4, concave part 4 can't hold the relatively big debris of volume.

Therefore, in the embodiment, the periphery of the water inlet 14 on the lower housing 12 is entirely inclined toward the water inlet 14, so that the gap between the roller brush 10 and the lower housing 12 can be increased while the roller brush 10 is maintained at the original position, that is, the accommodating space of the lower housing 12 is increased, so that relatively large-sized impurities can be accommodated, and the impurities are inclined toward the water inlet 14, and the inclination corresponds to a "downhill path", that is, the impurities can move toward the water inlet 14 by gravity, and the water inlet 14 provides a suction force to the impurities through the fan, so that the impurities can be influenced by the inclination when any part of the lower housing 12 has the impurities, and the impurities can move toward the water inlet 14 while the water inlet 14 absorbs the impurities by wind, so that the lower housing 12 can provide a reserved position for the rotation of the roller brush 10, namely, the accommodating space, and can prevent the rolling brush 10 from being stuck by the sundries in the operation process, so that the sundries and the sewage can smoothly enter the waste water tank from the water pumping inlet 14.

In this example, the periphery of the water pumping inlet 14 is inclined toward the direction of the water pumping inlet 14 to form a first inclined surface 121 and a second inclined surface 122, one end of the second inclined surface 122 is connected to the first inclined surface 121, the other end is connected to the water pumping inlet 14, and the inclination angle of the second inclined surface 122 is greater than that of the first inclined surface 121; if the whole lower shell 12 directly forms a larger inclination angle towards the water pumping water inlet 14, a larger space is formed in the middle between the water pumping water inlet 14 and the two sides of the lower shell 12 due to the overlarge inclination angles of the two sides, so that the wind suction force between the whole water inlet 14 and the two sides of the lower shell 12 is easily and directly weakened; from another perspective, the more the inclination angle of the inclined plane near the water inlet 14 is, the larger the gap between the water inlet 14 and the rolling brush 10 is, the stronger the wind force at the water inlet 14 is originally, and the weaker the wind force at the two sides of the lower shell 12 is, but if the gap between the water inlet 14 and the rolling brush 10 is too large, the wind force at the surface a of the rolling brush 10 opposite to the water inlet 14 is weakened, so that the sundries or the sewage at the position a is difficult to be adsorbed, and the weaker the wind force at the positions of the rolling brush 10 corresponding to the two sides of the lower shell 12 is, the sundries or the sewage at the position a is difficult to be adsorbed, and the cleaning difficulty is also larger.

Therefore, in the present embodiment, by setting the inclination of the lower housing 12 to be the first inclined surface 121 and the second inclined surface 122, and setting the second inclined surface 122 close to the water pumping inlet 14, the inclined surfaces can be divided into two, and the inclination angle of the second inclined surface 122 is larger than that of the first inclined surface 121, that is, the first inclined surface 121 can be inclined slowly towards the direction of the second inclined surface 122, and the inclination angle of the second inclined surface 122 is larger than that of the first inclined surface 121, that is, only the inclination angle of the second inclined surface 122 is larger, in order to deepen the understanding of the first inclined surface 121 and the second inclined surface 122, the first inclined surface 121 can be understood as a "gentle slope", the second inclined surface 122 can be understood as a "slope", and the second inclined surface 122 is connected to the water pumping inlet 14, so when the roller brush 10 is in operation, if sundries fall on the first inclined surface 121, the sundries can be moved slowly towards the direction of the second inclined surface 122 depending on the inclination angle, after the wind power falls into the second inclined plane 122, the wind power keeps a strong power because the space is not excessively enlarged, so that sundries and dirty water can be directly sucked away by the water pumping water inlet 14, and the situation that the sundries or the dirty water at the position A is difficult to be adsorbed cleanly due to the overlarge gap between the water pumping water inlet 14 and the rolling brush 10 can be avoided while the accommodating volume of the lower shell 12 is kept to be increased; preferably, the inclination angle of the first inclined surface 121 to the water inlet 14 direction is about 15 degrees, and the inclination angle of the second inclined surface 122 to the water inlet 14 direction is about 45 degrees.

In this embodiment, the air suction device further includes a third inclined plane 123 and a fourth inclined plane 124, one end of the third inclined plane 123 is connected to the water inlet 14, the other end of the third inclined plane is connected to the fourth inclined plane 124, the water inlet 14 is located in the middle of the lower casing 12, the first inclined plane 121 and the second inclined plane 122 are located on the left side of the water inlet 14, the third inclined plane 123 and the fourth inclined plane 124 are located on the right side of the water inlet 14, the water inlet 14 is disposed in the middle, and the third inclined plane 123 and the fourth inclined plane 124 are disposed on the right side of the lower casing 12, so that the air suction rate of the water inlet 14 can be increased.

It is understood that the pumping water inlet 14, the second inclined surface 122, and the third inclined surface 123 together form a bell mouth shape to form a first bell mouth-shaped structure, and the first inclined surface 121 and the fourth inclined surface 124 form another auxiliary second bell mouth-shaped structure at the periphery. The first bell mouth-shaped structure keeps stronger suction force because of the previous structure; the opening of second horn mouth column structure (keeping away from the one side of water inlet 14 promptly) is wider, but its holistic horn mouth column structure is more flat (the thickness of horn mouth column structure is less promptly), so, can maintain the space of a suitable size when expanding the mouth scope, and then also can keep certain suction strength in this scope, under this prerequisite, can clear up the rubbish that easily hides in casing 12 both sides down with certain wind-force way in enough big within range again, and because of having kept certain space, can absorb the great dirty granule that exists in this space, prevent that great dirty granule from locating jam and wearing and tearing at casing 12 down.

In this embodiment, the connection point between the first inclined plane 121 and the second inclined plane 122 is an arc, the connection point between the third inclined plane 123 and the fourth inclined plane 124 is an arc, and the arc is more smooth and fluent relative to a square shape by setting the connection point to be an arc, so that the sundries on the first inclined plane 121 and the fourth inclined plane 124 can be prevented from being stuck at the connection point when moving to the second inclined plane 122 and the third inclined plane 123.
