One embodiment of the present utility model provides a liquid storage tank for a cleaning device, which is suitable for a cleaning device, and the cleaning device may be a cleaning device such as a sweeping robot or a mopping machine, or may be other types of cleaning devices, such as a floor washing machine. As shown in fig. 1, the liquid storage tank for the cleaning device comprises a tank body 1 and a liquid discharge structure 2, wherein the tank body 1 is used for storing cleaning liquid, the liquid discharge structure 2 is arranged in the tank body 1, the liquid discharge structure 2 comprises a liquid discharge inclined surface structure 21 and a liquid discharge pipeline 22, a first end of the liquid discharge pipeline 22 is connected to the bottom end of the liquid discharge inclined surface structure 21, and a liquid discharge port is formed in a second end of the liquid discharge pipeline 22. Wherein the cleaning liquid in the tank 1 is configured to be guided to the first end of the drain pipe 22 by the drain slope structure 21 and to be discharged outside the tank 1 through the drain port of the drain pipe 22. The cleaning liquid can be water, water added with a cleaning agent or other liquid with cleaning capability.

It will be appreciated that the liquid discharge inclined surface structure 21 includes an inclined surface and a bottom end which are connected to each other, the inclined surface is inclined with respect to a horizontal plane, a first end of the inclined surface, which is far away from the liquid discharge pipeline 22, is a top end, a second end of the inclined surface, which is close to the liquid discharge pipeline 22, is provided with a bottom end, which is parallel to the horizontal plane, and the inclined surface is inclined downward in a direction which is close to the liquid discharge pipeline 22.

The liquid storage tank for the cleaning device provided by the embodiment comprises a tank body 1 for storing cleaning liquid, wherein a liquid draining structure 2 is arranged in the tank body 1, and the cleaning liquid in the tank body 1 is discharged to the maximum extent by utilizing a liquid draining inclined surface structure 21 of the liquid draining structure 2. In the actual use process, the liquid draining inclined surface structure 21 is at least partially arranged obliquely relative to the horizontal plane, and the cleaning liquid in the box body 1 flows from the liquid draining inclined surface structure 21 to the bottom end of the liquid draining inclined surface structure 21 under the action of self gravity. The first end of flowing back pipeline 22 is connected in the bottom of flowing back inclined plane structure 21, and the first end can directly accept the clean liquid that is located flowing back inclined plane structure 21 bottom, in the clean liquid of being convenient for was discharged to flowing back pipeline 22, and the second end of flowing back pipeline 22 is provided with the leakage fluid dram, and the leakage fluid dram is used for discharging the clean liquid in the flowing back pipeline 22 to the outside of box 1. In this way, under the interaction of the liquid draining inclined surface structure 21 and the liquid draining pipeline 22, the cleaning liquid draining speed is high, the efficiency is high, and the thorough draining of the cleaning liquid in the tank body 1 is facilitated.

In some embodiments, a water pump is connected to the second end of the drain pipe 22, and under the pumping action of the water pump, the cleaning liquid is sucked into the drain pipe 22, and then is discharged out of the tank 1 through the drain port.

In one embodiment, as shown in fig. 1, the height of the drain inclined surface structure 21 away from the first end of the drain pipe 22 is h1, and the height of the drain inclined surface structure 21 near the second end of the drain pipe 22 is h2; wherein h1 > h2.

It will be appreciated that if the heights of the both ends of the drain inclined surface structure 21 are approximately the same, the drain inclined surface structure 21 is approximately a horizontal structure, and the cleaning liquid in the tank 1 may flow in a dispersed manner in the drain inclined surface structure 21, so that it is difficult to drain and clean the cleaning liquid in the tank 1.

For this reason, the present embodiment provides a liquid discharge inclined surface structure 21 having a height h1 away from the first end of the liquid discharge pipe 22 greater than a height h2 of the liquid discharge inclined surface structure 21 near the second end of the liquid discharge pipe 22.

In one embodiment, h1-h2 > 1mm.

If h1-h2 is less than or equal to 1mm, it means that the difference in height between the first end of the drain inclined surface structure 21 away from the drain pipe 22 and the second end of the drain inclined surface structure 21 close to the drain pipe 22 is relatively small, and at this time, the heights of the two ends of the drain inclined surface structure 21 can be regarded as approximately the same, and it is difficult to achieve the drainage effect on the cleaning liquid in the tank 1. Meanwhile, the cleaning liquid in the tank 1 is dispersed and spread on the liquid discharge inclined surface structure 21, and it is difficult to empty and discharge the cleaning liquid in the tank 1. For this reason, the height difference between the first end of the drain inclined surface structure 21 far away from the drain pipe 22 and the second end of the drain inclined surface structure 21 close to the drain pipe 22 is greater than 1mm, so that the heights of the two ends of the drain inclined surface structure 21 are obviously different, and the cleaning liquid in the tank 1 is drained, and meanwhile, the cleaning liquid in the tank 1 is collected at the second end of the drain inclined surface structure 21 close to the drain pipe 22, so that the cleaning liquid in the tank 1 can be emptied as much as possible.

Specifically, a drain groove 211 is provided at a position approximately in the middle of the bottom end of the drain inclined surface structure 21, and the first end of the drain pipe 22 is connected to the bottom end of the drain inclined surface structure 21 through the drain groove 211, and the drain groove 211 serves as an intermediate connection to improve the reliable connection between the drain pipe 22 and the bottom end of the drain inclined surface structure 21. The liquid discharge pipeline 22 is communicated with the liquid discharge groove 211, which is equivalent to arranging the position of the liquid discharge pipeline 22 for sucking the cleaning liquid in the liquid discharge groove 211 with the groove structure, and after the cleaning liquid in the box body 1 is drained to the liquid discharge groove 211 through the inclined surface of the liquid discharge inclined surface structure 21, the liquid discharge groove 211 provides a certain accommodating space for the cleaning liquid, so that the liquid discharge pipeline 22 is convenient for sucking and discharging the cleaning liquid.

In one embodiment, the bottom of the drain groove 211 is lower than the bottom of the drain inclined surface structure 21, and the cleaning liquid in the tank 1 is configured to be guided into the drain groove 211 through the drain inclined surface structure 21.

Since the bottom of the drain groove 211 is lower than the bottom of the drain inclined surface structure 21, the bottom of the drain groove 211 is substantially the lowest position, the drain groove 211 further plays a role of drainage and convergence, and even when the total amount of cleaning liquid in the tank 1 is small, the cleaning liquid in the tank 1 can flow into the bottom of the drain groove 211 to the maximum extent for the drain pipe 22 to suck and discharge the cleaning liquid.

The outer peripheral wall of the liquid discharge joint 11 is provided with a communication hole which plays a role of intermediate communication, so that the cleaning liquid in the liquid discharge groove 211 flows into the liquid discharge pipeline 22 through the communication hole, and the cleaning liquid conveying and discharging process is realized.

In this way, the connection reliability of the drain pipe 22 and the drain joint 11 is improved, and the communication effect between the drain tank 211 and the drain pipe 22 is also achieved, so that the connection stability of the drain pipe 22 is improved, and the purpose of discharging the cleaning liquid is achieved.

In some embodiments, the drain connector 11 may be disposed at approximately the middle of the drain groove 211, i.e., the drain groove 211 is disposed around the drain connector 11. At this time, the side wall of the drain groove 211 on the side close to the drain inclined surface structure 21 guides the cleaning liquid on the drain inclined surface structure 21 to the drain groove 211, and the side wall of the drain groove 211 on the side far from the drain inclined surface structure 21 acts as a baffle plate, reducing the situation of the cleaning liquid overflowing from the drain groove 211.

In some other embodiments, if the bottom end of the liquid discharge inclined surface structure 21 is not provided with the liquid discharge groove 211, the bottom end of the liquid discharge inclined surface structure 21 is a relatively small plane, and the liquid discharge pipeline 22 is arranged on the plane, and the plane is connected with the inclined surface, the problem of partial liquid discharge guiding can be solved.

In normal use of the cleaning device, the efficiency of the liquid storage tank directly influences the efficiency of providing cleaning liquid, and if the liquid supply efficiency of the liquid storage tank is lower, the effect of mopping is directly influenced. For this reason, as shown in fig. 5 and 6, the drain inclined surface structure 21 provided in the present embodiment is provided at the bottom wall of the bottom case 12, and the cleaning liquid in the tank 1 is configured to be discharged through the drain pipe 22 connected to the bottom wall of the bottom case 12 when the tank 1 is in the upright state. The normal use refers to the cleaning device performing a cleaning task.

It will be appreciated that in normal use of the cleaning apparatus, the tank 1 is adapted to provide cleaning liquid to other structures, such as the wet cleaning structure 3, when the tank 1 is in an upright position, i.e. the bottom housing 12 is below the upper cover 13, and the upper cover 13 is above the bottom housing 12. The cavity in the bottom shell 12 provides an accommodating space for the liquid discharge pipeline 22, and the bottom shell 12 is connected with the liquid discharge pipeline 22 and simultaneously enables the cleaning liquid in the bottom shell 12 to be discharged through the liquid discharge pipeline 22 for the wet cleaning structure 3 and other structures.

The drain groove 211 is arranged at the bottom end of the drain inclined surface structure 21, the groove bottom height of the drain groove 211 is lower than the bottom end height of the drain inclined surface structure 21, at this time, the groove bottom of the drain groove 211 is the lowest position of the box body 1 in the upright state, so that cleaning liquid in the box body 1 is guided into the drain groove 211 through the drain inclined surface structure 21, and the drain groove 211 achieves collection of the cleaning liquid.

At this time, the liquid outlet connector 123 is a position where the liquid outlet pipe 122 absorbs the cleaning liquid, so that the cleaning liquid in the liquid outlet groove 211 enters the liquid outlet connector 123 through the communication hole of the liquid outlet connector 123 and is discharged through the liquid outlet pipe 122, and the cleaning liquid in the box 1 can be discharged to the maximum extent when the box 1 is in an upright state in normal use.

When the cleaning equipment fails and needs repairing and maintenance, if the cleaning liquid remained in the liquid storage tank cannot be completely discharged, certain difficulty is brought to factory returning and maintenance. For this reason, as shown in fig. 5 and 7, the drain inclined surface structure 21 provided in the present embodiment is provided on the inner wall of the upper cover 13, the second end of the drain pipe 22 is communicated with the water flow passage 121, and the cleaning liquid in the tank 1 is configured to be discharged through the drain pipe 22 and through the water flow passage 121 when the tank 1 is in an inverted state.

It will be appreciated that when the cleaning apparatus is subjected to factory return maintenance, the cleaning liquid remaining in the tank 1 needs to be discharged, and the tank 1 may be in an inverted state, i.e., the upper cover 13 is located below the bottom cover 12, and the bottom cover 12 is located above the upper cover 13. The cavity enclosed by the upper cover 13 and the bottom shell 12 provides an accommodating space for the liquid discharge pipeline 22, the upper cover 13 is connected with the liquid discharge pipeline 22, and the residual cleaning liquid in the tank body 1 can be discharged through the liquid discharge pipeline 22.

Wherein, the upper cover 13 is connected with a liquid inlet pipe 131, a liquid inlet joint 132 is arranged at the bottom of the liquid discharge groove 211, when the tank body 1 is in an inverted state, the liquid inlet pipe 131 is the liquid discharge pipeline 22, the liquid inlet joint 132 is the liquid discharge joint 11, and a communication hole is arranged at the liquid inlet joint 132.

Specifically, the inner wall of the upper cover 13 is provided with the liquid draining inclined surface structure 21, when the tank body 1 is in an inverted state, the height difference between the first end of the liquid draining inclined surface structure 21, which is far away from the liquid inlet water pipe 131, and the second end of the liquid draining inclined surface structure 21, which is close to the liquid inlet water pipe 131, is greater than 1mm, so that the heights of the two ends of the liquid draining inclined surface structure 21 are obviously different, and the liquid draining function on the cleaning liquid in the tank body 1 is achieved. The bottom of the liquid draining inclined surface structure 21 is provided with a liquid draining groove 211, the groove bottom height of the liquid draining groove 211 is lower than the bottom height of the liquid draining inclined surface structure 21, at the moment, the groove bottom of the liquid draining groove 211 is the lowest position of the box body 1 in an inverted state, so that cleaning liquid in the box body 1 is guided into the liquid draining groove 211 through the liquid draining inclined surface structure 21, and the liquid draining groove 211 achieves convergence of the cleaning liquid.

At this time, the liquid inlet connector 132 is a position where the liquid inlet pipe 131 sucks the cleaning liquid, so that the cleaning liquid in the liquid drain tank 211 flows into the liquid inlet connector 132 through the communication hole of the liquid inlet connector 132, is discharged through the liquid inlet pipe 131, and is finally sucked out and discharged through the water flow channel 121, so that the cleaning liquid remaining in the tank 1 can be discharged to the maximum extent when the tank 1 is in an inverted state.

In one embodiment, as shown in fig. 5 to 7, the bottom wall of the bottom case 12 and the inner wall of the upper cover 13 are each provided with a drain slope structure 21, the cleaning liquid in the tank 1 is configured to be discharged through a drain pipe 22 connected to the bottom wall of the bottom case 12 when the tank 1 is in an upright state, and the cleaning liquid in the tank 1 is configured to be discharged through the drain pipe 22 connected to the inner wall of the upper cover 13 and through the water flow passage 121 when the tank 1 is in an inverted state.

With the arrangement, when the box body 1 is required to be normally used in an upright state and the box body 1 is required to be repaired in an inverted state, the box body 1 can realize emptying of clean liquid, the drain inclined surface structures 21 are arranged on the bottom wall of the bottom shell 12 and the inner wall of the upper cover 13, residual clean liquid in the box body 1 is discharged to the maximum extent by utilizing the drain inclined surface structures 21, the efficiency of discharging the clean liquid is improved, and after-sale maintenance is facilitated.

In some embodiments, when the cleaning apparatus is in an operating state for performing a cleaning task, the cleaning apparatus is in an upright state, the cleaning base station provides the cleaning liquid to the liquid tank through the water flow channel 121 of the bottom shell 12, the cleaning liquid flowing in from the water flow channel 121 enters the liquid inlet water pipe 131 and flows into the tank 1 through the communication hole provided at the liquid inlet joint 132, at this time, the cleaning liquid falls into the bottom shell 12 from the position of the upper cover 13, and the communication hole of the liquid inlet joint 132 plays a role of flowing the liquid in the liquid inlet water pipe 131 into the water tank 1, so that the wet cleaning structure 3 realizes a mopping process.

In some embodiments, when the cleaning apparatus is in a maintenance operation state, the cleaning apparatus may be in an inverted state, the upper cover 13 is located below the bottom shell 12, the cleaning liquid in the tank 1 may drain to the drain tank 211 through the drain inclined surface structure 21 disposed on the inner wall of the upper cover 13, and under the suction effect of the external force, the cleaning liquid enters into the liquid inlet water pipe 131 through the communication hole of the liquid inlet connector 132, and is sucked out of the tank 1 through the water flow channel 121.

It should be noted that, the cleaning apparatus is provided, that is, the tank 1 is in an inverted state to discharge the cleaning liquid, mainly because the speed of discharging the cleaning liquid in a manner that the tank 1 is in an upright state to perform the cleaning task is slow, and the tank 1 is placed in an inverted state, and the cleaning liquid is discharged through the water flow channel 121, so that the discharging of the cleaning liquid can be accelerated by fully utilizing the high suction characteristic of the cleaning base station. It will be appreciated that instead of the tank 1 being maintained in an inverted position, the tank 1 is in an inverted position more conducive to the discharge of cleaning liquid.

It will be appreciated that the flow paths and the main functions of the cleaning liquid in the liquid inlet pipe 131 and the communication hole are different in the case 1 in two different states of standing and standing.
