The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Reference Figure 1 and Figure 2The present disclosure provides a sewage tank, comprising a tank body 2, a tank cover 1 and a partition 5. The tank body 2 is provided with a sewage inlet channel extending in the axial direction of the sewage tank. The tank cover 1 is detachably mounted on the tank body 2. The tank cover 1 is provided with an air outlet and a baffle 3 extending into the tank body 2 in the axial direction of the sewage tank. The baffle 3 is configured to block the sewage flowing out through the sewage inlet channel. The partition 5 is fixed on the tank cover 1 and extends into the tank body 2 in the axial direction. The partition 5 is configured to prevent the sewage from entering the air outlet when the cleaning device is lying flat.

[0035] Furthermore, the enclosure 3 may be configured as a semi-enclosed structure or a fully-enclosed structure.

[0036] When the enclosure 3 is a semi-enclosed structure, the enclosure 3 and the housing 2 form an enclosed area 30 that surrounds the sewage inlet channel, thereby blocking the sewage flowing out of the sewage outlet of the sewage inlet channel.

[0037] Specifically, the enclosure 3 includes a first enclosure plate 31 and a second enclosure plate 32 that are arranged opposite to each other, and a third enclosure plate 33 that connects a group of corresponding edges (311, 321) of the first enclosure plate 31 and the second enclosure plate 32. The first enclosure plate 31, the second enclosure plate 32 and the third enclosure plate 33 are long strips extending along the axial direction of the sewage tank. One end of the first enclosure plate 31, the second enclosure plate 32 and the third enclosure plate 33 is fixedly connected to the box cover 1, and the other end is a free end. Among them, it is best to set the first enclosure plate 31 and the second enclosure plate 32 symmetrically with the axis of the sewage tank as the symmetry axis. When the box cover 1 is assembled on the box body 2, the other group of corresponding edges (312, 322) of the first enclosure plate 31 and the second enclosure plate 32 are sealed and connected to the inner wall of the box body 2, and the first enclosure plate 31, the second enclosure plate 32, the third enclosure plate 33 and the inner wall of the box body 2 together constitute the enclosed area 30.

[0038] The first enclosure plate 31 has a first extension edge 311 and a second extension edge 312 which are arranged oppositely, and the second enclosure plate 32 has a third extension edge 321 and a fourth extension edge 322 which are arranged oppositely, the first extension edge 311 and the third extension edge 321 are connected to the third enclosure plate 33, and the second extension edge 312 and the fourth extension edge 322 are sealed to the inner wall of the shell 2. As a specific embodiment, the second extension edge 312 and the fourth extension edge 322 are respectively in contact with the shell 2 and the inner wall of the box body 2, and the two extension edges of the first enclosure plate 31 and the second enclosure plate 32 which are away from the third enclosure 33 are respectively provided with limiting grooves, and sealing strips are arranged in the limiting grooves, and the sealing strips are used to achieve the sealing of the contact parts between the first enclosure plate 31 and the second enclosure plate 32 and the inner wall of the box body 2.

[0039] When the enclosure 3 is a fully enclosed structure, the enclosure 3 forms an enclosed area 30 that encloses the sewage inlet channel, thereby blocking the sewage flowing out of the sewage outlet of the sewage inlet channel.

[0040] The enclosure 3 includes a first enclosure plate 31 and a second enclosure plate 32 which are arranged opposite to each other, and a third enclosure plate 33 and a fourth enclosure plate (not shown) which respectively connect two groups of corresponding edges of the first enclosure plate 31 and the second enclosure plate 32. The first enclosure plate 31, the second enclosure plate 32, the third enclosure plate 33 and the fourth enclosure plate are long strips extending along the axial direction of the sewage tank. One end of the first enclosure plate 31, the second enclosure plate 32, the third enclosure plate 33 and the fourth enclosure plate is fixedly connected to the tank cover 1, and the other end is a free end. The first enclosure plate 31, the second enclosure plate 32, the third enclosure plate 33 and the fourth enclosure plate enclose the enclosed area 30.

[0041] Furthermore, the partition 5 is disposed between the enclosure 3 and the inner wall of the box body 2 and connected to the enclosure 3 as a whole. The partition 5 is a plate formed by extending the outer wall of the enclosure 3 toward the inner wall of the box body 2. The partition 5 extends to abut against the inner wall of the box body 2, and the partition 5 is sealed and connected to the inner wall of the box body 2. Specifically, a protrusion 50 perpendicular to the partition 5 is provided on the edge of the partition 5 abutting against the inner wall of the box body 2, and a sealing strip is provided on the end surface of the protrusion 50 facing the inner wall of the box body 2.

[0042] Furthermore, the plane where the partition 5 is located is parallel to or angled with the axis of the box body 2, so that when the cleaning device is lying flat, the partition 5 can isolate the sewage below the partition 5 to prevent the sewage from entering the air outlet 10. The length of the partition 5 extending along the axial direction of the sewage tank is not less than the length of the enclosure 3 extending along the axial direction of the sewage tank. In order to better isolate the sewage, the length of the partition 5 extending along the axial direction of the sewage tank is consistent with the length of the enclosure 3 extending along the axial direction of the sewage tank. Preferably, the partition 5 is arranged above the axis of the sewage tank so that the partition can block most of the sewage.

[0043] As a preferred embodiment, the air outlet 10 is arranged above the plane where the partition 5 is located. When the cleaning equipment is lying flat, the sewage isolated under the partition 5 cannot enter and is discharged through the air outlet 10 located above the partition 5, thereby avoiding damage to the suction motor, circuit board and other components.

[0044] As another preferred embodiment, the air outlet 10 is arranged between the partition 5 and the enclosure 3, and the sewage tank is constructed with an airflow channel 40 connected with the air outlet 10 between the partition 5 and the enclosure 3, and a blocking plate 43 for blocking the airflow or sewage is provided in the airflow channel 40, and the blocking plate 43 cooperates with the partition 5 to prevent sewage from entering the air outlet 10. At the same time, the blocking plate 43 can also reduce the water vapor carried in the airflow, and reduce the loss of the water vapor in the airflow to the suction motor, circuit board and other components.

[0045] Specifically, the sewage tank also includes at least one first airflow plate 41 extending along the axial direction of the sewage tank and at least one second airflow plate 42 extending along the axial direction of the sewage tank. The first airflow plate 41 is arranged between the first baffle plate 31 and the inner wall of the box body 2 and / or between the second baffle plate 32 and the inner wall of the box body 2. The second airflow plate 42 connects the first airflow plate 41 with the corresponding edges of the first baffle plate 31 or the second baffle plate 32. The first airflow plate 41, the second airflow plate 42 and the first baffle plate 31 or the second baffle plate 32 together form the airflow channel 40.

[0046] The partition 5 is arranged between the first airflow plate 41 and the inner wall of the box body 2. The partition 5 is arranged vertically or approximately vertically to the first airflow plate 41. The edge of the first airflow plate 41 perpendicular to the axis direction of the sewage tank is higher than the partition 5. In this way, when the cleaning equipment is lying flat, sewage can be prevented from entering the airflow channel 40.

[0047] In actual use, it is found that the length of the second airflow plate 42 in the axial direction of the sewage tank will affect the moisture content entrained in the gas during exhaust. When the length of the second airflow plate 42 in the axial direction of the sewage tank is equal to or the same as the length of the enclosure 3 in the axial direction, the water flowing on the inner wall of the enclosure 3 will enter the outer wall and accumulate or adhere at the end, so that the gas discharged from the air outlet channel will entrain a large amount of moisture. When the length of the second airflow plate 42 in the axial direction of the sewage tank is less than the length of the enclosure 3 in the axial direction, the water at the end of the enclosure 3 will flow out through the opening formed by the misalignment of the two, thereby reducing the moisture content entrained in the gas during exhaust. Therefore, the length of the first airflow plate 41 and the second airflow plate 42 extending in the axial direction of the sewage tank is less than the length of the enclosure 3 extending in the axial direction of the sewage tank.

[0048] In some embodiments, the sewage tank further includes a surge protection component 6, between which is a baffle 3 and a partition 5, and the surge protection component 6 and the tank cover 2 are configured to weaken or eliminate the surge of sewage when the cleaning device is lying flat.

[0049] The surge prevention assembly 6 includes an end baffle 61 and a valve plate 62. The plane where the end baffle 61 is located is perpendicular to or at an angle to the axis of the sewage tank. The end baffle 61 is provided with a plurality of filter holes, which are radially spread from the center of the end baffle 61 to the edge of the end baffle 61. The filter holes can be set to be elliptical, circular or other shapes. The valve plate 62 is set on the side of the baffle 61 away from the enclosure 3 and blocks part of the filter holes. When the cleaning equipment is tilted or tipped, the sewage on the left side of the end baffle 61 can only enter the right side through a few filter holes under the action of the valve plate 62 to reduce surge.

[0050] The projection of the end baffle 61 in the axial direction is at least larger than half of the cross-sectional area of ​​the box body 2 where the end baffle 61 is located, and the area of ​​the valve plate 62 is less than half of the cross-sectional area of ​​the box body 2 where the valve plate 62 is located, which can effectively improve the surge effect.

[0051] The present invention also provides a cleaning device, which comprises the above-mentioned sewage tank.

[0052] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to the above embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without removing the spirit or scope of the present invention. Therefore, the present invention will not be limited to the above embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
