[0002] With the development of science and technology, more and more electrical appliances have entered our lives, and sweeping robots are common electrical appliances in our homes. At present, sweeping robots on the market are usually robots for vacuuming and cleaning dry garbage. There are fewer sweeping robots that need to clean and mop the floor. In the sweeping robots for cleaning and mopping, the sewage suction component is its core component. The sewage suction component is a component on the sweeping and mopping unmanned robot that realizes the sewage suction function. When the robot performs the floor washing task, it will spray clean water on the ground, and the robot will use a roller brush to clean the ground. The water suction squeegee behind the robot will gather the sewage and then the sewage will be sucked by the sewage suction component to store it in the sewage tank inside the robot. Since the sewage on the ground is relatively small, a large suction force is required to suck it, and then a small amount of sewage and a large amount of air are sucked up. At this time, water and gas separation is required; for this reason, the applicant has designed and produced a new type of unmanned sweeping robot sewage suction component according to the needs of this type of robot. This component can achieve efficient gas-water separation, the upper part removes air dust-free and aseptically, and the lower part filters the sewage and stores it in the sewage tank, which is efficient and fast.

DETAILED DESCRIPTION

[0012] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: like Figure 1-5 As shown, a novel unmanned sweeping robot sewage suction component is shown, including a water separation volute 1, a sewage suction fan volute 2, a high-speed brushless fan 3, an exhaust port 4, a sewage suction pipe port 5, a sewage outlet 6, a sewage return pipe 7, a sewage tank 8 and a mounting seat 9, as shown Figure 1 As shown, the new unmanned sweeping robot sewage suction component is provided with a water separation volute 1, the water separation volute 1 is a cylindrical structure, and is made of environmentally friendly plastic integral injection molding. A sewage suction fan volute 2 is installed on the top of the water separation volute 1. The sewage suction fan volute 2 and the water separation volute 1 are made of the same material. The sewage suction fan volute 2 and the water separation volute 1 are designed to be split and fixed by bolts; Figure 5As shown, a water separation core 2-1 is arranged at the lower part of the volute 2 of the suction fan, and a filter chamber 2-2 is installed at the upper part of the water separation core 2-1. The water separation core 2-1 can quickly separate sewage and air, and the filter chamber 2-2 can remove moisture and dust carried in the air for a second time to prevent the sweeping robot from discharging polluted air; a sewage suction pipe opening 5 is arranged on the upper left side of the water separation volute 1, and a corrugated structure is arranged on the sewage suction pipe opening 5, which is convenient for connecting with the pipeline; a sewage discharge outlet 6 is arranged at the lower part of the water separation volute 1, and a one-way valve is arranged at the sewage discharge outlet 6, which can make the sewage no longer return to the water separation volute 1 after being discharged into the sewage tank 8, affecting the water separation function; a mounting seat 9 is arranged on the water separation volute 1, and is fixed inside the unmanned sweeping robot through the mounting seat 9; the interior of the water separation volute 1 is sucked A rotating volute 1-1 is arranged at the rear end of the sewage pipe outlet 5, which is downward close to the bottom. The sewage is quickly discharged through the sewage outlet 6 at the bottom under the action of gravity. An air pressure balance pipe 1-2 is arranged at the center of the water-dividing volute 1, connecting the sewage tank to the top side of the water-dividing volute 1. When working, the air pressure balance pipe 1-2 generates a certain suction force on the sewage tank 8, so that the sewage at the bottom of the water-dividing volute 1 can be quickly discharged into the sewage tank 8; a high-speed brushless fan 3 is installed on the top of the sewage suction fan volute 2, and an exhaust port 4 is arranged on the right side of the sewage suction fan volute 2; the lower part of the sewage outlet 6 is connected to the sewage return pipe 7, and the lower part of the sewage return pipe 7 is connected to the sewage tank 8. A sewage discharge solenoid valve 8-1 is arranged at the bottom of the sewage tank 8. When sewage needs to be discharged, the sewage discharge solenoid valve 8-1 can be opened to discharge it quickly.

[0013] After the new unmanned sweeping robot sewage suction component is installed on the sweeping robot with cleaning and mopping function, the high-speed brushless fan 3 runs to provide strong suction to the inside of the water-dividing volute 1 during operation, and the sewage suction pipe connected to the sewage suction pipe port 5 provides strong suction to the ground to be cleaned. The sucked sewage and air are initially separated in the water-dividing volute 1, and then filtered through the water-dividing core 2-1, and then filtered again through the filter bin 2-2, and then the separated air is discharged through the exhaust port 4. At the same time, the air pressure balance pipe 1-2 arranged inside the water-dividing volute 1 generates a certain suction to the sewage tank 8, so that a certain negative pressure is formed in the sewage tank 8. At this time, it is more conducive to the sewage deposited at the bottom of the water-dividing volute 1 to be quickly discharged into the sewage tank. After cleaning the ground, the sewage in the sewage tank 8 is quickly discharged by opening the sewage discharge solenoid valve 8-1, which is convenient for next use.

[0014] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any modification or equivalent change made based on the technical essence of the present invention still falls within the scope of protection required by the present invention.
