In the present invention, the above-mentioned mass equality can be understood as: the mass of the medium in the first zone Z1 is exactly equal to the mass of the medium in the second zone Z2, or the mass of the medium in the first zone Z1 is approximately equal to the mass of the medium in the second zone Z2, or the mass of the medium in the first zone Z1 and the mass of the medium in the second zone Z2 are equal when there is no medium. In this specification, "substantially" may be understood as approaching, approximating, or being within a predetermined range from a target value. Through the way, no matter how the capacities of the first medium in the first accommodating cavity 111 and the second medium in the second accommodating cavity 112 are changed, the quality of the medium on two sides of the vertical plane Z in the box body 100 is always equal, and the box has the advantages of uniform mass distribution and stable mass center distribution.

In the present invention, the distribution of the number of the second receiving cavities 112 includes the following cases: first, the number of the second receiving cavities 112 is only one; second, the number of the second receiving cavities 112 is at least two. When the number of the second receiving cavities 112 is only one, the second receiving cavities 112 are distributed on the periphery of the first receiving cavity 111 in a circular ring shape, and of course, the second receiving cavities 112 may also be square, oval, or other regular or irregular shapes. When the number of the second accommodating cavities 112 is at least two, the combined center of mass of the plurality of second accommodating cavities 112 is the second center of mass. In order to obtain the above-mentioned combined center of mass, the second accommodating cavities 112 are symmetrically distributed outside the first accommodating cavity 111, and the capacities of the second media in the second accommodating cavities 112 are equal, so that the above-mentioned combined center of mass can be obtained more conveniently. The second receiving cavities 112 are symmetrically distributed on the outer side of the first receiving cavity 111 in the following manner: first, the second receiving cavities 112 are distributed on two sides of the first receiving cavity 111 in an axisymmetric manner; secondly, the second accommodating cavities 112 are distributed outside the first accommodating cavity 111 in a centrosymmetric manner; thirdly, the second receiving cavities 112 are distributed outside the first receiving cavities 111 in a rotational symmetric manner.

When there are two second receiving cavities 112, please refer to fig. 5, the two second receiving cavities 112 are distributed on two sides of the first receiving cavity 111 in an axisymmetric manner, or a centrosymmetric manner, or a rotational symmetric manner, in which case, the first receiving cavity 111 and the second receiving cavity 112 are distributed on the same straight line.

When there are three second receiving cavities 112, in an embodiment, as shown in fig. 10, the three second receiving cavities 112 are surrounded to form an equilateral triangle, the first receiving cavity 111 is located at the center of the equilateral triangle, where the center is formed by combining the center of gravity, the vertical center, the inner center, and the outer center of the equilateral triangle, and at this time, the three second receiving cavities 112 may be distributed outside the first receiving cavity 111 in an axisymmetric manner or a rotationally symmetric manner; in another embodiment, referring to fig. 11, three second receiving cavities 112 are defined to form an isosceles triangle, the first receiving cavity 111 is located at a midpoint of a bottom side of the isosceles triangle, and at this time, the three second receiving cavities 112 are distributed outside the first receiving cavity 111 in an axisymmetrical manner.

It can be understood that, when the four second receiving cavities 112 are surrounded to form a rectangle, the second receiving cavities 112 are located at the intersection point of the diagonal lines thereof, and at this time, the second receiving cavities 112 may be distributed outside the first receiving cavity 111 in an axisymmetric or centrosymmetric manner.

When the second medium is a fluid medium, in order to equalize the quality of the second medium in each second receiving cavity 112, it is necessary to ensure that the distribution heights of the second medium in each second receiving cavity 112 are consistent. The method for achieving the distribution height consistency of the second medium is as follows: first, the plurality of second receiving cavities 112 are communicated with each other, specifically, as shown in fig. 4, two adjacent second receiving cavities 112 are communicated with each other through a fluid channel 130, and the fluid channel 130 is disposed in the box body 100, so that the distribution heights of the second media in the second receiving cavities 112 can be consistent. The position of the fluid channel 130 is preferably set at the bottom of the second receiving cavity 112, and may be set at the middle or other positions. It is understood that the two adjacent second receiving cavities 112 can be communicated with each other through a pipe or other connection means. Secondly, the inflow and outflow of each second receiving cavity 112 is controlled so that the inflow and outflow of each second receiving cavity 112 are consistent, thereby ensuring that the distribution heights of the second medium in each second receiving cavity 112 are consistent.

In the present invention, the cross-sectional shape of the first receiving cavity 111 is a symmetrical figure, the cross-sectional shape is a plane perpendicular to the vertical plane Z, the cross-sectional shape of the first receiving cavity 111 is an axisymmetric figure, or a centrosymmetric figure, and specifically, the cross-sectional shape of the first receiving cavity 111 is a rectangle, an ellipse, an isosceles trapezoid, a cone, a rhombus, a regular polygon with an even number of sides, or the like. Specifically, when the cross-sectional shape of the first receiving cavity 111 is an axisymmetric pattern or a centrosymmetric pattern, the position of the vertical plane Z is fixed and is located on the symmetric plane of the first receiving cavity 111 regardless of the change of the first medium in the first receiving cavity 111, and at this time, the vertical plane Z can be regarded as the vertical symmetric plane of the first receiving cavity 111.

Having described the specific structure of the tank structure in full, those skilled in the art will understand the following principles, and for ease of understanding, the tank structure is illustrated as applied to a scrubber.

Specifically, referring to fig. 6 and 7, the scrubber has a central axial plane M, which is symmetrical with respect to the central axial plane M, wherein the central axial plane M is a vertical plane distributed along the forward direction of the scrubber, and the driving wheels on the scrubber are symmetrically distributed with respect to the central axial plane M. The tank body 100 is arranged inside the machine body of the washing machine and is positioned in the middle of the machine body of the washing machine. The first receiving cavity 111 can be regarded as a sewage tank of the floor washing machine, and is used for receiving sewage on a cleaning roller of the floor washing machine and dirt cleaned by the cleaning roller, and a mixture of the sewage and the dirt is a first medium received by the first receiving cavity 111. The second receiving chamber 112 can be regarded as a clean water tank of the scrubber, in which cleaning liquid is stored, the cleaning liquid being a second medium received in the second receiving chamber 112, and the clean water tank being used for conveying the cleaning liquid to the cleaning roller.

The first accommodating cavity 111 is provided with a dirt inlet 1111 and an air outlet 1112; the sewage inlet 1111 is used for allowing sewage and dirt to enter the first accommodating cavity 111; the air outlet 1112 is used for allowing the dust-containing gas to flow out of the first receiving cavity 111. A liquid outlet 1121 for discharging liquid from the second accommodating cavity 112 is arranged on the second accommodating cavity 112, and the second accommodating cavity 112 conveys cleaning liquid to the cleaning roller of the floor washing machine through the liquid outlet 1121 so as to wet the cleaning roller of the floor washing machine. Referring to fig. 5, the liquid outlet 1121 is communicated with the second receiving cavity 112 through a filter cover unit, and the filter cover unit is disposed in the second receiving cavity 112. The filter cover unit comprises a water outlet filter cover 1126 arranged at the bottom of the second accommodating cavity 112 and a water conveying pipe 1127 communicated with the water outlet filter cover 1126 and the liquid outlet 1121.

The forward direction of the scrubber is defined as the front, the backward direction of the scrubber is defined as the back, and the two sides of the front and back direction of the scrubber are defined as the left and right directions. During the forward movement of the scrubber, the first receiving chamber 111 continuously sucks in the dirty water on the cleaning roller and the dirt on the floor, and simultaneously, the second receiving chamber 112 continuously delivers the cleaning liquid to the cleaning roller. In the above process, the first medium mass in the first receiving cavity 111 and the second medium mass in the second receiving cavity 112 are continuously changed. The box structures on the market can not ensure that the medium quality in the box structures on the left side and the right side of the central axis M is equal all the time. When the floor washing machine operates, the acting forces generated by the driving wheels at the two sides by the different medium masses at the two sides of the middle shaft surface M are different, so that the problem of poor operation stability of the floor washing machine is caused. When the box body structure is installed, the quality of media in the box bodies 100 on the left side and the right side of the central axis plane M can be always equal only by ensuring that the vertical plane Z of the box body structure is overlapped with the central axis plane M of the floor washing machine, and therefore the problem of poor operation stability of the floor washing machine caused by the fact that the quality of the two sides of the central axis plane M is inconsistent can be effectively solved.

In the utility model, when the first mass center a and the second mass center B are located on the same vertical plane Z, only the media quality on the left and right sides of the vertical plane Z in the box body 100 can be ensured to be equal, but the media quality on the front and rear sides in the box body 100 cannot be ensured to be equal. If the medium quality in the box body 100 in the front, rear, left and right directions of the vertical plane Z is to be kept consistent, the first mass center a and the second mass center B are required to be located on the same vertical straight line of the vertical plane Z.

Referring to fig. 2, 5, 8 and 9, in an embodiment, the number of the second receiving cavities 112 is two, the second receiving cavities 112 are symmetrically disposed on two sides of the first receiving cavity 111, and the first receiving cavity 111 and the second receiving cavity 112 are disposed on an extension line of a same straight line, so as to form a distribution structure in which the first receiving cavity 111 is located in the middle and the second receiving cavity 112 is located on two sides of the first receiving cavity 111. The first accommodating cavity 111 and the second accommodating cavity 112 are both symmetrical structures, the vertical plane Z coincides with the symmetrical plane of the first accommodating cavity 111, and the symmetrical plane of the second accommodating cavity 112 is parallel to the vertical plane Z. In the utility model discloses, the first barycenter a of the first medium in the first accepting chamber 111 that is shown in fig. 8 and fig. 9 the second barycenter B of the second medium in the second accepting chamber 112 lie in vertical plane Z but can't lie in same vertical straight line, the reason is as follows: the first receiving cavity 111 and the second receiving cavity 112 have irregular shapes, and the shape of the first receiving cavity 111 is different from that of the second receiving cavity 112, so that a first centroid a of a first medium in the first receiving cavity 111 and a second centroid B of a second medium in the second receiving cavity 112 are different in the front and rear directions of the vertical plane Z. The shape of the first receiving cavity 111 is the shape shown by the dashed line box in fig. 8; the shape of the second receiving cavity 112 is shown by a dotted line box in fig. 9.

Therefore, when the amount of sewage and dirt is large, the volume of the first accommodating cavity 111 is increased by moving the blocking part G towards the first accommodating cavity 111; when more cleaning liquid is needed, the blocking member G is moved toward the second accommodating cavity 112 to increase the volume of the second accommodating cavity 112, so that the volumes of the first accommodating cavity 111 and the second accommodating cavity 112 can be flexibly adjusted according to actual use conditions, and the cleaning liquid container has the advantage of convenience in use.

Considering that the cleaning liquid in the second receiving cavity 112 is consumed when the scrubber is in operation, the cleaning liquid needs to be periodically supplied to the second receiving cavity 112.

It is considered that if the first receiving cavity 111 is not emptied in time after being fully loaded, the cleaning effect of the floor cleaning machine is affected. In the present invention, a liquid discharge port is provided at the bottom of the first receiving chamber 111. The liquid discharge ports may be divided into a manual liquid discharge port for manual liquid discharge and an automatic liquid discharge port for automatic liquid discharge, and it is understood that the manual liquid discharge port and the automatic liquid discharge port may be provided in the first housing chamber 111 at the same time, or one of them may be provided.
