[0039] The present invention provides a separation device.

[0040] See also Figures 1 to 7 The separation device 1 proposed in the present invention includes a cleaning box 11, a separation member 12 and a water spray assembly 13; the cleaning box 11 has a cleaning chamber 16, a water collecting chamber 17 and a dust suction duct 18, the cleaning chamber 16 is used to collect dust, the water collecting chamber 17 is located below the cleaning chamber 16, the water collecting chamber 17 has a water collecting port 171 connected to the cleaning chamber 16, and the dust suction duct 18 has a dust suction port 181 connected to the cleaning chamber 16; the separation member 12 is arranged at the water collecting port 171, and is used to separate dust and water; the water spray assembly 13 is arranged in the cleaning chamber 16, and is used to spray water to the cleaning assembly 3 of the sweeping robot.

[0041] In the embodiment of the present invention, the shape of the cleaning box 11 is various, and the cleaning box 11 can be in the shape of a cube or a cylinder. The upper end of the cleaning box 11 can extend upward to form the cleaning chamber 16, and the cleaning chamber 16 is located at the bottom of the cleaning component 3; the side of the cleaning box 11 can also extend outward to form the cleaning chamber 16, and the cleaning chamber 16 is located on one side of the cleaning component 3. The water collection port 171 can be circular, square or polygonal. The water collection port 171 can be arranged at the bottom of the cleaning chamber 16, or at one side of the cleaning chamber 16. The dust suction duct 18 can be arranged above the water collection chamber 17, or at one side of the water collection chamber 17. The dust suction port 181 can also be circular, square or polygonal. The dust suction port 181 can be arranged opposite to the separator 12. Of course, the dust suction port 181 may not be arranged opposite to the separator 12.

[0042] The shape of the separator 12 can be circular, square or polygonal, so that the separator 12 is adapted to the shape of the water collection port 171. Figure 5 The separator 12 is covered at the water collection port 171, and the water in the cleaning chamber 16 can pass through the separator 12 into the water collection chamber 17 (as shown by the black arrow in the figure), while the dust in the cleaning chamber 16 cannot pass through the separator 12 into the water collection chamber 17 (as shown by the gray arrow in the figure), so the separator 12 separates the dust from the water. The separator 12 can be arranged horizontally, vertically or obliquely in the cleaning box 11. The number of the separators 12 can be one or more.

[0043] The water spray assembly 13 may be disposed below the cleaning chamber 16, so that the water spray assembly 13 sprays water toward the cleaning assembly 3 located above. The water spray assembly 13 may also be disposed on one side of the cleaning chamber 16, so that the water spray assembly 13 sprays water toward the cleaning assembly 3 located on one side. For easy disassembly and assembly, the water spray assembly 13 may be detachably connected to the cleaning box 11, such as by snap-fit ​​connection, adhesive connection or screw connection. The number of the water spray assembly 13 may be one or more.

[0044] The separation device 1 of the present invention comprises a cleaning box 11, a separation member 12 and a water spray assembly 13. The cleaning box 11 has a cleaning chamber 16, a water collection chamber 17 and a dust suction duct 18. The cleaning chamber 16 is used to collect dust. The water collection chamber 17 is located below the cleaning chamber 16. The water collection chamber 17 has a water collection port 171 connected to the cleaning chamber 16. The dust suction duct 18 has a dust suction port 181 connected to the cleaning chamber 16. The separation member 12 is disposed at the water collection port 171 to separate dust and water. The water spray assembly 13 is disposed in the cleaning chamber 16 to spray dust on the floor. The cleaning component 3 of the robot sprays water; in this way, the water spray component 13 sprays water to the cleaning component 3, and the cleaning component 3 rotates along the axial direction of the cleaning component 3, and the dust and water on the cleaning component 3 are splashed onto the separator 12, and the separator 12 separates the dust and water, and the water in the cleaning chamber 16 passes through the separator 12 and drips / flows down due to gravity, and flows into the water collecting chamber 17 through the water collecting port 171, and the dust in the cleaning chamber 16 falls along the surface of the separator 12 due to gravity, and is sucked into the dust suction duct 18 through the dust suction port 181. In this way, dust is not easy to be blocked in the cleaning chamber 16, thereby improving the cleaning effect of the cleaning component 3.

[0045] See also Figure 1 , Figure 2 and Figure 5, the cleaning box 11 includes a cleaning cover 111 and a cleaning seat 112, the cleaning cover 111 and the cleaning seat 112 enclose the water collecting chamber 17, the cleaning cover 111 is recessed downward to form the cleaning chamber 16, and the water collecting port 171 is formed on the cleaning cover 111.

Specifically, the cleaning cover 111 includes a first cover portion 111a and a second cover portion 111b, the first cover portion 111a is in the shape of a flat surface, and the second cover portion 111b is in the shape of an arc surface, and the first cover portion 111a and the second cover portion 111b are arranged to form the cleaning chamber 16. In this way, the shape of the cleaning cover 111 is more compatible with the shape of the bottom of the sweeping robot, and has a better connection effect. Of course, the shape of the cleaning chamber 16 can also be roughly U-shaped. The water collection port 171 may be formed at the bottom of the cleaning chamber 16, so that the water in the cleaning chamber 16 is relatively easy to flow into the water collection chamber 17 through the water collection port 171 under the force of gravity. Of course, the water collection port 171 may also be formed on one side of the cleaning chamber 16. The cleaning cover 111 and the cleaning seat 112 may be integrally formed, or may be detachably connected, such as adhesively connected, snap-fitted connected, or screwed connected.

[0046] See also Figure 2 and Figure 5 In one embodiment, the cleaning box 11 further includes an air duct component 113, which is mounted on the cleaning seat 112 and enclosed with the cleaning seat 112 to form the dust suction air duct 18.

The air duct plate 113a can also be arranged parallel to the horizontal plane. The air duct plate 113a is tilted downward in the direction toward the separator 12, so that the dust and water dripping / flowing on the air duct plate 113a can be easily flowed down from the air duct plate 113a, and then separated by the separator 12.

[0048] See also Figure 2 and Figure 5 , the air duct component 113 also includes an air outlet 113b, the air outlet 113b is surrounded to form a dust outlet duct 182 connected to the dust suction duct 18, the number of the air outlet 113b is two, and they are arranged at intervals along the length direction of the air duct plate 113a.
