[0070] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0071] With the development of economy and the progress of society, people have higher and higher requirements for the quality of life, so some smart appliances that can free people's hands have emerged, and cleaning equipment for home use has gradually entered people's lives. Now the cleaning equipment is a floor scrubber as an example, and the technical solution of this application is further described.

[0072] A floor scrubber is a cleaning device that is suitable for cleaning the floor and sucking out the sewage at the same time, and taking the sewage away from the site. It has the advantages of environmental protection, energy saving, and high efficiency. The sewage tank is an important part of the floor scrubber. It is used for gas-liquid separation and collects the separated sewage in its own cavity. The amount of sewage stored in the sewage tank needs to be tested to determine whether the sewage tank needs to be cleaned.

[0073] In the related art, after the cleaning equipment is finished running, it is necessary to clean the inside of the sewage tank. There is solid waste in the sewage in the sewage tank, and it is inconvenient to pour out the solid waste in the sewage tank together with the sewage, which affects the user experience.

[0074] In a first aspect of the present application, the present application provides a sewage separator, which is used to be installed on a sewage tank of a cleaning device.

[0075] Figure 1 shows a schematic structural diagram of a sewage tank in one or more embodiments of the present application, Figure 2 Shows Figure 1 A schematic diagram of the structure of the sewage tank cover assembly from the first perspective. Figure 1 as well as Figure 2 The sewage tank cover assembly a includes a cover body 1 and a partition 2. Figure 3 Shows Figure 2 Schematic diagram of the structure of the sewage separator. Figure 1-Figure 3 The sewage separator includes a partition 2, which is provided with a first water leakage portion 202. The partition 2 divides the sewage tank b into a first cavity located above the partition 2 and a second cavity located below the partition. The first cavity and the second cavity are connected through the first water leakage portion 202.

[0076] The sewage separator provided by the present application has a partition 2 that divides the sewage tank b into a first cavity located above the partition 2 and a second cavity located below the partition 2. After the sewage sucked into the sewage tank b together with the solid waste is sucked into the first cavity, the sewage flows into the second cavity through the first water leakage part 202 to achieve solid-liquid separation in the sewage tank. When cleaning the sewage tank, it is only necessary to pull the sewage separator away from the sewage tank b. During the pulling process, the sewage in the sewage tank b flows into the sewage tank through the first water leakage part 202, and the solid waste in the sewage remains on the partition 2 of the sewage separator, so that the sewage separator and the sewage tank b can be dumped separately to quickly clean up the solid waste and sewage, thereby improving the user experience and having good practicality.

[0077] Combination Figure 3 The partition 2 can be in the shape of a plate, and is provided in the mounting hole 201 for the suction pipe e of the sewage tank b to pass through. When the sewage tank b is used, the sewage in the sewage tank b is collected into the first cavity through the suction pipe e, and the water in the sewage collected into the first cavity is drained into the second cavity through the first leaking part 202, so that the solid waste in the sewage is stored in the first cavity, and the sewage is separated into solid and liquid through the partition 2.

[0078] Figure 4 Shows Figure 3 Schematic diagram of top view. Figure 3 as well as Figure 4 In some embodiments, the first water leakage portion 202 on the partition 2 may include a plurality of first water leakage holes, and the plurality of first water leakage holes may be arranged in an arc shape around the mounting hole 201. In other embodiments, the plurality of first water leakage holes on the partition 2 may also be arranged in a grid shape, which is not limited here.

[0079] In some embodiments, the sewage tank b has a mounting side wall, the water pumping pipe e is connected to the mounting side wall of the sewage tank b, and the mounting hole 201 is open toward one side of the mounting side wall for the water pumping pipe e to pass through. In specific implementation, the water pumping pipe e can be integrated into the mounting side wall of the sewage tank b, and a water outlet is provided on the top of the water pumping pipe e. When the sewage tank b is used, the sewage in the sewage tank b is collected into the first cavity through the top of the water pumping pipe e, and the water in the sewage collected into the first cavity is drained into the second cavity through the first water leakage part 202, so that the solid waste in the sewage is stored in the first cavity, and the sewage is separated into solid and liquid through the partition 2. In other embodiments, a water outlet can also be provided on the peripheral surface of the water pumping pipe e above the partition 2, and the sewage in the sewage tank b can also be collected into the first cavity, which is not limited here.

[0080] Combination Figure 2-Figure 4 , at least part of the periphery of the partition 2 is elastically abutted against the inner wall of the sewage tank b to improve the sealing effect between the partition 2 and the inner wall of the sewage tank b. In some embodiments, a first sealing member 203 may be provided at the periphery of the partition 2 except for the opening, and the water suction pipe e and the opening may be fitted with a small gap. Of course, the first sealing member 203 may also be provided between the pipe wall and the opening of the water suction pipe e, which will not be described in detail here. In other embodiments, the periphery of the partition 2 may be elastic, for example, a plate of elastic material may be injection molded at the periphery of the partition 2, so that when the sewage divider is assembled in the sewage tank b, the periphery of the partition 2 may be appropriately compressed to improve the sealing effect between the partition 2 and the inner wall of the sewage tank b.

[0081] Figure 5 Shows Figure 3 Another structural diagram of the perspective. Figure 2-Figure 5 The sewage separator may further include a garbage baffle 3, which is connected to the partition 2 and is disposed in the first cavity, that is, the garbage baffle 3 is connected to the top of the partition 2, and a second water leakage portion 301 is disposed on the garbage baffle 3, and the first water leakage portion 202 is disposed on one side of the garbage baffle 3. When the sewage separator is disassembled from the sewage tank b, the garbage baffle 3 can concentrate the garbage in the sewage tank b on the area surrounded by the partition 2 and the garbage baffle 3, so as to prevent the garbage from falling directly on the ground, avoid secondary pollution, and facilitate the cleaning of the garbage.

[0082] Combination Figure 2-Figure 5In some embodiments, the garbage baffle 3 may be connected only to at least a portion of the periphery of the partition 2. For example, the garbage baffle 3 is preferably connected to the rear side of the partition 2. In actual implementation, when the user removes the sewage divider from the sewage tank b, the sewage tank b will face the user, that is, the sewage tank b is tilted to the rear side. When the garbage baffle 3 is connected to the rear side of the partition 2, when the sewage divider is removed, if there is sewage in the first cavity, the sewage will flow to the area behind the garbage baffle 3 through the second water leakage part 301 on the garbage baffle 3, and the garbage will be stored in the area in front of the partition 2 and the garbage baffle 3, so that the user can clean the garbage conveniently.

[0083] Combination Figure 3 as well as Figure 5 In some embodiments, the second water leakage part 301 may include a second water leakage hole arranged in a grid shape on the garbage baffle 3 to prevent sewage from remaining at the junction of the garbage baffle 3 and the partition 2, so as to avoid the phenomenon of leakage outside the sewage tank b and causing secondary pollution after the sewage separator is disassembled.

[0084] Combination Figure 2-Figure 5 In some embodiments, the first water leakage part 202 can be arranged at the front side of the garbage baffle 3 to be used for the fixed separation of the first cavity and the second cavity of the partition 2. A avoidance part 302 is arranged at least partially on the rear side of the garbage baffle 3, and the avoidance part 302 extends to the front side of the partition 2 to form a guide groove. The partition 2 is provided with a third water leakage part 204, and at least part of the third water leakage part 204 is arranged in the projection of the avoidance part 302. The third water leakage part 204 can be a third water leakage hole, which is arranged directly below the avoidance part 302. When the cleaning device is in use, there is sewage between the garbage baffle 3 and the sewage tank b. The avoidance part 302 and the third water leakage part 204 are arranged to allow the sewage to flow into the sewage tank, which plays a diversion role. When the sewage separator is disassembled, the sewage located at the rear side of the garbage baffle 3 can flow into the sewage tank b through the avoidance part 302 and the third water leakage part 204. In other embodiments, there may be a gap between the garbage baffle 3 and the rear side wall of the box body b1 of the sewage tank b, and the front and rear sides of the garbage baffle 3 are both provided with a first water leakage portion 202. When the sewage separator is disassembled, the sewage flow located on the rear side of the garbage baffle 3 can flow into the sewage tank b through the above-mentioned gap and the third water leakage portion 204.

[0085] In other embodiments, the garbage baffle 3 can also be arranged around the top of the partition 2, and when the sewage divider is disassembled, the garbage is retained on the partition 2 between the garbage baffles 3. However, this assembly method can only be used to invert the sewage divider or manually clean the garbage. Compared with the above-mentioned solution in which the garbage baffle 3 is connected to part of the periphery of the partition 2, the garbage cleaning is simpler and is a preferred solution.

[0086] In the second aspect of the present application, the present application further provides a sewage tank cover assembly a, which includes a cover body 1 and the above-mentioned sewage separator, and a partition 2 of the sewage separator is connected to the bottom of the cover body 1. Wherein, when the sewage tank cover assembly a is assembled in the sewage tank b, the partition 2 divides the sewage tank b into a first cavity located above the partition 2 and a second cavity located below the partition 2, and the first cavity and the second cavity are connected through the first leaking part 202.

[0087] The sewage tank cover assembly a provided by the present application has a partition 2 connected to the bottom of the cover body 1. When the sewage tank cover assembly a is assembled in the sewage tank b, the partition 2 divides the sewage tank b into a first cavity located above the partition 2 and a second cavity located below the partition 2. After the sewage sucked into the sewage tank b together with the solid waste is sucked into the first cavity, the sewage flows into the second cavity through the first leaking part 202 to achieve solid-liquid separation in the sewage tank b. When cleaning the sewage tank b, it is only necessary to pull the sewage tank cover assembly a away from the sewage tank b. During the pulling process, the sewage in the sewage tank b flows into the sewage tank b through the first leaking part 202, and the solid waste in the sewage remains on the partition 2 of the sewage tank cover assembly a, so that the sewage tank cover assembly a and the sewage tank b can be dumped separately to quickly clean up the solid waste and sewage, thereby improving the user experience and having good practicality.

[0088] Combination Figure 2 In some embodiments, the sewage tank cover assembly a further comprises a flow guide 4, which is arranged above the mounting hole 201. When the sewage tank cover assembly a is assembled in the sewage tank b, the flow guide 4 is arranged above the water suction pipe e. When the sewage tank b is used, the sewage in the sewage tank b is sprayed out through the top of the water suction pipe e, and after being blocked by the flow guide 4, it is collected in the first cavity.

[0089] Combination Figure 2 In a specific implementation, the guide member 4 can be a U-shaped structure, the opening of the U-shaped structure of the guide member 4 faces downward, and the side walls on both sides of the guide member 4 can be connected to the partition 2 through the bracket 5.

[0090] Combination Figure 2 In some embodiments, a sealing plate 401 may be provided on the rear side of the guide member so that the guide groove forms a cover structure with a bottom and a front opening.

[0091] In addition, in the related art, when the floor scrubber is running, the water in the sewage tank may collide with the inner wall of the sewage tank to generate water splashes. When the draft element is running, the water splashes may be sucked into the draft element, affecting the normal operation of the draft element.

[0092] Based on the above technical problems, the present application provides a sewage tank cover assembly, which, under the condition of including the above-mentioned partition, the cover body 1 is also provided with an air inlet 102, and the parts of the cover body 1 located on both sides of the air inlet 102 abut against the inner wall of the sewage tank b, so that the first cavity can be roughly divided into two parts, and the splashes generated by the water located in the part facing away from the air inlet 102 will be blocked by the parts of the cover body 1 located on both sides of the air inlet 102, so as to avoid to a certain extent the risk of splashes generated by the collision of the water in the sewage tank b with the inner wall of the sewage tank b being sucked into the air inlet member d, so that the air inlet member d can operate normally, and it has good practicality.

[0093] Combination Figure 2 In some embodiments, the cover body 1 can be integrally formed on the top of the guide member 4, and the air inlet 102 is arranged on the side wall of the cover body 1, that is, the air inlet 102 is arranged above the guide member 4. The cover body 1 is also connected to two water retaining members 7, which are arranged on both sides of the air inlet 102. When the sewage tank cover assembly a is assembled in the sewage tank b, the two water retaining members 7 abut against the inner wall of the sewage tank b. The two water retaining members 7 and the cover body 1 can roughly divide the first cavity into two parts. The water splash generated by the part of the water facing away from the air inlet 102 will be blocked by the water retaining members 7 of the cover body 1 located on both sides of the air inlet 102, so as to avoid the risk of the water splash generated by the collision between the water in the sewage tank b and the inner wall of the sewage tank b being sucked into the air induction member d to a certain extent, so that the air induction member d can operate normally.

[0094] In some embodiments, the air inlet 102 can be arranged at the front side of the cover body 1, and two water retaining members 7 are arranged on both sides in the width direction of the cover body 1. The two water retaining members 7 and the cover body 1 can divide the first cavity into two parts, front and back. When the cleaning device is in a backward tilted or flat state, the two water retaining members 7 can block water below the two water retaining members 7 (behind the upper part of the sewage tank b), preventing the splashes caused by the collision of water with the sewage tank b cover bracket 5 from being sucked into the air outlet, so that the air induction member d can operate normally.

[0095] In some embodiments, the two water retaining members 7 can be integrally formed with the sewage tank b, and at least part of the two water retaining members 7 can elastically abut against the inner wall of the sewage tank b to improve the sealing effect between the water retaining members 7 and the inner wall of the sewage tank b. In specific implementation, a second sealing member 701 (such as Figure 2 Alternatively, the outer side of the water retaining member 7 may be elastic, for example, a plate made of elastic material may be injection molded on the outer side of the water retaining member 7, so that when the sewage tank cover assembly a is assembled in the sewage tank b, the periphery of the water retaining member 7 may be appropriately compressed to improve the sealing effect between the water retaining member 7 and the inner wall of the sewage tank b.

[0096] Combination Figure 2In some embodiments, an air outlet cavity 101 is provided on the cover body 1, an air inlet 102 is provided on the side wall of the air outlet cavity 101, and a water retaining portion 103 is provided at the bottom of the air outlet cavity 101 to prevent the sewage in the sewage tank b from entering the air outlet cavity 101. When the cleaning device is in a forward or lying state, the water retaining portion 103 can prevent the water in the sewage tank b from entering the air outlet cavity 101 through the air inlet 102, and also prevent the water from further entering the air inducing member d, thereby protecting the air inducing member d. When the cleaning device is tilted in other directions, since the air inlet 102 is not provided at other places of the air outlet cavity 101, the water in the sewage tank b cannot enter the air outlet cavity 101, thereby improving the phenomenon that the water in the sewage tank b enters the air inducing member d through the air inlet 102, so as to ensure the normal operation of the air inducing member d to a certain extent, and has good practicality.

[0097] In some embodiments, at least a portion of the bottom of the air outlet cavity 101 is provided with an inclined surface, the side of the inclined surface facing the air inlet 102 is lower than the side of the inclined surface away from the air inlet 102, and the inclined surface is configured as a water retaining portion 103. When the cleaning device is in a forward or lying position, the water retaining portion 103 can prevent the water in the sewage tank b from entering the air outlet cavity 101 through the air inlet 102, and also prevent the water from further entering the air induction member d, thereby protecting the air induction member d. The inclined surface can be provided with only one, or multiple (such as Figure 6 The slopes of the multiple inclined surfaces may be consistent or inconsistent, and there is no limitation on this.

[0098] In other embodiments, at least part of the bottom of the air outlet cavity 101 may also be provided with a step, which may be configured as a water retaining portion 103. When the cleaning device is in a forward or flat position, the water retaining portion 103 may prevent the water in the sewage tank b from entering the air outlet cavity 101 through the air inlet 102, and also prevent the water from further entering the air induction member d, thereby protecting the air induction member d. The step may be provided with only one, or may be provided with multiple steps (such as a step 103 and a step 104). Figure 7 ), no limitation is given here.

[0099] In the related art, if the sewage tank b is in an inclined posture, the water surface in the sewage tank b is close to the draft member d, and water droplets may be generated on the water surface in the sewage tank b. When the draft member d is running, too many water droplets may be sucked into the draft member d, affecting the normal operation of the draft member d.

[0100] Based on the above technical problems, the present application continues to improve the sewage tank cover assembly a. Figure 8 Shows Figure 2 A schematic diagram of the structure of the second perspective, Fig. 9 Shows Figure 2A schematic diagram of the third perspective structure. Figure 8 as well as Fig. 9 The sewage tank cover assembly a also includes two first electrodes 8, which are respectively connected to the cover body 1, and each first electrode 8 has a first trigger part 801, which is used to generate a trigger signal when the two first trigger parts 801 are conducted by the water in the sewage tank b, so that the cleaning equipment adjusts the operating parameters of the air induction member d according to the corresponding trigger signal.

[0101] Fig.10 Shows that there is Figure 1 The schematic diagram of the logic control of the cleaning equipment of the sewage tank is shown. Fig.10 The sewage tank cover assembly a provided in the present application, when the water in the sewage tank b conducts the two first trigger parts 801, the two first trigger parts 801 generate a trigger signal, so that the cleaning device adjusts the operating parameters of the air induction member d according to the corresponding trigger signal, so as to reduce the operating power of the air induction member d when the sewage tank b is in an inclined posture, thereby reducing the risk of water droplets generated on the surface of the water in the sewage tank b being sucked into the air induction member d, so that the air induction member d can operate normally, and has good practicality. The inclined posture is set as the target posture. When the cleaning device is in other postures, there is no water between the two first trigger parts 801, the first trigger part 801 and the second trigger part 1001 are not conductive, and no trigger signal for adjusting the operating parameters of the air induction member d is generated, and the air induction member d returns to the normal set power value to enable the device to operate normally.

[0102] Combination Fig.10 The cleaning device may also include a controller c. When the sewage tank b is in the target posture, the water in the sewage tank b conducts the two first trigger parts 801 to output a trigger signal to the controller c. The trigger signal can be defined as a first trigger signal. The controller c that receives the first trigger signal outputs a control signal to the air inducing member d to reduce the operating power of the air inducing member d, thereby reducing the risk of water droplets generated on the surface of the water in the sewage tank b being sucked into the air inducing member d, so that the air inducing member d can operate normally. When the sewage tank b is not in the above-mentioned target posture, there is no water between the two first trigger parts 801, the two first trigger parts 801 are not conducting, the controller c cannot receive the above-mentioned first trigger signal, and the air inducing member d accordingly cannot receive the control signal, and the air inducing member d restores the normal set power value to enable the device to operate normally.

[0103] In the related art, when the floor scrubber is running, the inclined sewage tank b will produce more water droplets on the surface of the water in the sewage tank b compared to the sewage tank b in the vertical state. Based on this, the target posture of the sewage tank b shown in the present application is set as the inclined posture of the sewage tank b, that is, Fig.11 shown.

[0104] In addition, when the user pushes and pulls the floor scrubber, more water droplets will be generated on the surface of the water in the sewage tank B. Based on this, the sewage tank B shown in the present application is in a condition where it is tilted toward the back of the sewage tank B, that is, the sewage tank B is tilted toward the user, and the posture of the sewage tank B is set as the target posture.

[0105] In some embodiments, the inclination angle of the sewage tank b can be less than or equal to 20°, that is, when the sewage tank b is at this inclination angle, the controller c is triggered to output a control signal to reduce the operation of the air induced component d. When the sewage tank b is at other angles, the air induced component d maintains the normally set operating power, so that the mopping machine has good cleaning efficiency.

When the sewage tank b is in the target posture and the water in the sewage tank b submerges the first triggering parts 801 of the two first electrodes 8, the water in the sewage tank b turns on the first triggering parts 801 of the two first electrodes 8 to transmit the control signal to the controller c.
