The robot main body and the driving wheel module have a conventional structure of a cleaning robot, and a detailed description of the specific structure thereof will not be provided herein.

Referring to fig. 1 and 2, the liquid storage tank 100 includes a tank body 110 and a gas permeable tube 120. Next, the box 110 and the ventilation tube 120 will be described in detail.

As for the box 110, please refer to fig. 1 and fig. 2, which includes a first wall 111, a second wall 112 and a third wall 113; wherein the first wall 111 is adjacent to the second wall 112. In this embodiment, the first wall 111 is a top wall of the box body 110, the second wall 112 is a side wall of the box body 110, and the third wall 113 is a bottom wall of the box body, that is: the first wall 111 is adjacent to the second wall 112, the third wall is opposite to the first wall 111, and the first wall 111, the second wall 112 and the third wall 114 together form a liquid storage cavity 114 for containing cleaning liquid. Specifically, the third wall 113 has a plate-like structure as a whole; the second wall 112 extends from the contour boundary of the third wall 113, and is surrounded by at least two side wall units; the first wall 111 is disposed at an end of the second wall 112 away from the third wall 113, and is fixed to the second wall 112, and encloses the liquid storage chamber 114 together with the second wall 112 and the third wall 113. More specifically, the second wall 112 is enclosed by four side wall units, namely a first side wall unit 1121, a second side wall unit 1122, a third side wall unit 1123, and a fourth side wall unit 1124; the first sidewall unit 1121 and the second sidewall unit 1122 are disposed opposite to each other, the third sidewall unit 1123 and the fourth sidewall unit 1124 are disposed opposite to each other and disposed between the first sidewall unit 1121 and the second sidewall unit 1122, respectively, and two ends of the third sidewall unit 1123 and the fourth sidewall unit 1124 are connected to the first sidewall unit 1121 and the second sidewall unit 1122, respectively. The third wall 113 and the second wall 112 are integrally formed, specifically, integrally formed in an injection molding manner, and the first wall 111 and the second wall 112 are fixedly connected in a detachable manner, specifically, in a snap connection manner. In the present invention, the connection manner among the first wall 111, the second wall 112, and the third wall 113 is not particularly limited, and in another embodiment of the present invention, the first wall, the second wall, and the third wall may be integrally formed.

Referring to fig. 1, 2 and 4, a liquid filling opening 1111 is formed on an outer surface of the first wall 111, the liquid filling opening 1111 is connected to the liquid storage chamber 114, and a user can fill the liquid storage chamber 114 with cleaning liquid through the liquid filling opening 1111. Meanwhile, in order to prevent the cleaning liquid from overflowing from the liquid filling port 1111, the tank body 110 further includes a liquid filling port cover body 115, and the liquid filling port cover body 115 is detachably fixed to the liquid filling port 1111 and seals the liquid filling port 1111. The outer surface of the first wall 111 is further provided with a vent 1112, and two ends of the vent 1112 are respectively communicated with the liquid storage cavity 114 and the external environment of the box body 110. Air in the external environment can enter the liquid storage cavity 114 through the vent 1112, and then the air pressure in the liquid storage cavity 114 is maintained to be basically the same as the external atmospheric pressure, so that the defect that the liquid pumping process is not smooth due to the gradual reduction of the air pressure in the liquid storage cavity 114 in the liquid pumping process of the liquid pump is avoided.

Optionally, in order to avoid the liquid injection port cover 115 protruding out of the first wall 111, on one hand, the occupied volume of the whole liquid storage box 100 is slightly increased, which is not easy to install, and on the other hand, the aesthetic property of the whole liquid storage box 100 is affected, a sink 1113 is disposed on the outer surface of the first wall 111, and the liquid injection port 1111 and the vent 1112 are disposed on the bottom surface of the sink 1113. The liquid inlet cover 115 is also disposed in the groove 1113 and is detachably mounted on the first wall 111. It is understood that in other embodiments of the present invention, the liquid injection port and the sink may be disposed at an end of the second wall close to the first wall.

Referring to fig. 3 and 4, the ventilation tube 120 is disposed in the liquid storage chamber 114, and has a hollow tubular structure, and includes a first connection portion 121 and a second connection portion 122. One end of the first connecting portion 121 is fixed to the vent 1112 of the first wall 111, and the other end extends to the edge of the third wall 113 in a direction away from the first wall 111. One end of the second connecting portion 122 is connected to one end of the first connecting portion 121 away from the first wall 111, and the other end extends to the edge of the second wall 112; in this embodiment, an end of the second connection portion 122 away from the first connection portion 121 extends to an edge of the first sidewall unit 1121, but it should be understood that in other embodiments of the present invention, the second connection portion may also extend to other sidewall units. Since the liquid storage chamber 114 is generally not filled with the cleaning liquid contained in the liquid storage tank 100, when the user turns the cleaning robot over until the third wall 113 of the liquid storage tank 100 faces upward, the end of the vent tube 120 away from the first wall 111 will be higher than the liquid level, and the cleaning liquid cannot overflow the liquid storage tank 100 through the vent 1112; in addition, even if the liquid storage tank is filled with the cleaning liquid, the liquid level after the cleaning robot is turned over at this time is higher than the end of the vent pipe 120 away from the first wall 111, but the liquid difference between the liquid level and the end of the vent pipe 120 away from the liquid level is very small, and the water pressure formed by the liquid difference is smaller than the sum of the pressure of the external atmospheric pressure and the resistance of the inner wall of the vent pipe 120 to the cleaning liquid, that is: the cleaning solution does not overflow the tank 100 through the purge tube 120. In addition, sometimes the user needs to turn the cleaning robot to the third wall 113 and the first wall 111 to be upright, and similarly, when the user turns the cleaning robot to the first sidewall unit 1121 (i.e. the end of the ventilation tube 120 away from the first wall 111) to be upward, the cleaning liquid will not overflow the liquid storage tank 100. In summary, when the first wall 111 faces upward, or the third wall 113 faces upward, or the portion of the second wall 112 corresponding to the end of the vent tube 120 away from the first wall 111 faces upward, the cleaning liquid will not overflow through the vent hole 1112, that is, the cleaning robot can effectively improve the situation that the cleaning liquid overflows through the vent hole 1112 during the process of turning over the cleaning robot. It should be mentioned that, instead of the second connection portion being located entirely at the edge of the third wall 113, a technical solution that the cleaning liquid cannot overflow when the third wall faces upward can be achieved, but only that the vent pipe is located at least partially at the edge of the third wall 113; thus, when the turnover robot is turned upwards, the liquid level will be lower than the highest position of the vent pipe 120, and the cleaning liquid can not overflow through the vent pipe 120.

Alternatively, the inner diameter of the ventilation tube 120 is 0.5mm to 1.2mm, so that even if the cleaning robot is turned over until the third sidewall unit 1123 or the fourth sidewall unit 1124 faces upward and the tank 100 is in the static state, the liquid level of the cleaning liquid is higher than the pressure of the hydraulic pressure of the part of the ventilation tube 120 on the liquid inside the ventilation tube 120, and the sum of the pressure of the external atmospheric pressure on the liquid inside the ventilation tube 120 and the frictional resistance of the inner wall of the ventilation tube 120 on the liquid inside the ventilation tube 120 is maintained in a balanced state, the cleaning liquid will not overflow from the ventilation tube 120 and the ventilation hole 1122.

Further, the vent holes 1112 are disposed at the edge of the second sidewall unit 1122 so that the cleaning liquid does not overflow the tank 100 when the user turns the cleaning robot to the position where the end of the vent tube 120 away from the first wall 111 faces upward or downward. When the end of the air permeable tube 120 away from the first wall 111 faces downward, the air vent 1112 is higher than the liquid level of the cleaning solution, that is, the cleaning solution will not overflow the liquid storage tank 100 even in a slight shaking state; in addition, the principle of the ventilation tube 120 with the end away from the first wall 111 facing upwards is not described in detail herein. Further, at least one of the vent holes 1112 and the end of the vent tube 120 away from the first wall 111 is located at the edge of the third sidewall unit 1123, and similarly, when the user turns the cleaning robot over to the first sidewall unit 1121, the second sidewall unit 1122 or the third sidewall unit 1123 upward, the cleaning solution does not overflow the liquid storage tank 100. Further, when one of the ends of the vent holes 1112 and the vent pipes away from the first wall 111 is disposed at the edge of the third sidewall unit 1123 and the other end is disposed at the edge of the fourth sidewall unit 1124, the cleaning solution will not escape from the liquid storage tank 100 when the user turns the cleaning robot over to the position where the first sidewall unit 1121, the second sidewall unit 1122, the third sidewall unit 1123 or the fourth sidewall unit 1124 is facing upward, that is: no matter the user turns the cleaning robot to the side of the liquid storage tank 100 upward, the cleaning liquid will not overflow the liquid storage tank 100 even if it is in a slight shaking state.

Further, to facilitate the installation of the ventilation pipes 120, the tank further includes installation pipes 130. Specifically, continuing with fig. 4, the mounting tube 130 is disposed in the reservoir 114, fixed to an end of the first wall 111 facing the reservoir 114, and disposed around the periphery of the vent 1112, and a communication hole (not shown) communicating with the vent 1112 is disposed inside the mounting tube 130 and penetrates through the mounting tube 130. One end of the vent tube 120 close to the first wall 111 is mounted on the vent tube and is connected with the vent tube in a sealing manner, and in the embodiment, one end of the first connecting part 121 is mounted on the inner wall of the communication hole in an interference fit manner, so that the vent tube is fixedly mounted and is connected with the communication hole in a sealing manner. Namely: the vent 1112 is indirectly in communication with the internal conduit of the vent 120 via the mounting tube 130, and in turn is in communication with the reservoir 114 via the vent 120. It is understood that, in other embodiments of the present invention, the first connection portion may also be sleeved on the outer wall of the installation tube 130 in an interference fit manner; the vent tube may be fixed to the first wall directly, for example, by gluing, instead of being fixed to the first wall 111 by a mounting tube, and the inner tube of the vent tube is in communication with the vent hole at the end of the first wall adjacent to the vent tube.

Further, to prevent the cleaning liquid present in the breather tube 120 itself from overflowing the tank 100 through the above-mentioned vent hole, the tank further includes a stopper (not shown). The blocking member is installed in the inner pipe of the vent pipe 120 and is disposed at one end of the vent pipe 120 close to the first wall 111, and the blocking member is used for preventing the cleaning liquid inside the vent pipe 120 from overflowing the liquid storage tank 100 through the vent holes 1112. In this embodiment, the blocking member is a filter cotton, and the filter cotton is installed in the inner pipe of the first connecting portion 121; on one hand, air in the external environment can enter the liquid storage cavity 114 through the vent 1112, the communication hole and the inner pipeline of the vent pipe 120 in sequence to ensure that the liquid pumping process is smoothly performed; on the other hand, in the process of turning over the cleaning robot, a small amount of cleaning solution in the vent pipe 120 flows to the filter cotton and is absorbed by the filter cotton, so that the cleaning solution in the vent pipe 120 cannot overflow the liquid storage tank 100; on the other hand, the filter cotton can also effectively prevent impurities such as dust in the external environment from entering the ventilation pipe 120 and the liquid storage cavity 114. It is understood that in other embodiments of the present invention, the blocking member can be any other member that can effectively block the overflow of the cleaning liquid; for example: in some embodiments, the barrier is a sponge disposed at an end of the gas permeable tubing proximate the first wall; another example is: in some embodiments, the blocking member is a waterproof breathable film, and the waterproof breathable film is fixed on the first wall of the box body, specifically on the outer surface or the inner surface of the first wall, and completely covers the vent hole, so that even if the cleaning solution in the breathable pipe moves to the vent hole, the waterproof breathable film can also effectively prevent the cleaning solution from overflowing outwards.

It should be understood that even though the first wall 111, the second wall 112 and the third wall 113 in this embodiment are respectively a top wall, a side wall and a bottom wall of the box body 110, the present invention is not limited thereto. For example, in another embodiment of the present invention, the first wall, the second wall and the third wall are respectively a bottom wall, a side wall and a top wall of the tank body, that is, at this time, the vent hole is opened in the bottom wall, one end of the vent pipe is fixed to the bottom wall, and the other end extends to the edge of the side wall, so that when the top wall faces upward and the liquid level of the cleaning solution is lower than the end of the vent pipe far away from the bottom wall, or when the bottom wall faces upward, or when the side wall and the end of the vent pipe far away from the first wall face upward, the cleaning solution will. For another example, in another embodiment of the present invention, the first wall, the second wall and the third wall are a side wall, a top wall and a bottom wall of the box body, respectively, that is, at this time, the vent hole is opened in the side wall, one end of the vent pipe is fixedly installed on the side wall, and the other end extends to the top wall, so that the cleaning solution does not overflow no matter the top wall is upward or the portion of the side wall with the vent hole is upward. For another example, in still other embodiments of the present invention, the first wall, the second wall and the third wall are a side wall, a bottom wall and a top wall of the box body, respectively, which are similar to the above-mentioned manner for improving the distance of the overflow of the cleaning liquid, and therefore, the description thereof is omitted. The above embodiments can effectively improve the overflow condition of the cleaning liquid.

In some embodiments, the cleaning robot further includes a cleaning module for dry-type sweeping work and wet-type sweeping work, which is configured to be able to receive the cleaning liquid output from the tank 100 for the performance of the wet-type sweeping work. The specific form in which the cleaning module receives the cleaning liquid is not particularly limited; in some embodiments, the cleaning module directly receives the cleaning solution output from the tank 100 through a conduit, and particularly, one end of the conduit is connected to the tank, and the other end of the conduit is disposed at the edge of the cleaning module, so that the cleaning solution output from the tank 100 flows to the cleaning module through the conduit and wets the cleaning module and the ground, thereby completing the wet cleaning operation; in other embodiments, the cleaning module receives the cleaning solution output from the liquid storage tank 100 through the liquid pump and the conduit, and specifically, two ends of one conduit are respectively connected to the input ends of the liquid storage tank and the liquid pump, and two ends of the other conduit are respectively connected to the output end of the liquid pump and the cleaning module, so that the cleaning solution output from the liquid storage tank sequentially flows through the conduit, the liquid pump and the other conduit to wet the cleaning module and the ground, thereby facilitating the wet cleaning operation.

The cleaning robot provided by the embodiment of the invention comprises a robot main body, a driving wheel module, a liquid storage tank 100 and a cleaning module. The liquid storage tank 100 includes a tank body 110 and a vent pipe 120. The housing 110 has a reservoir 114, which includes a first wall 111 and a second wall 112, and the first wall 111 has a vent 1112 for communicating the reservoir 114 with the external environment. The vent tube 120 is disposed in the reservoir 114, and has one end mounted to the vent 1112 of the first wall 111 and the other end extending to the edge of the second wall 112 of the housing. Because the cleaning solution in stock solution chamber 114 generally can not fill up stock solution chamber 114 completely, then this cleaning robot of upset is to air vent 1112 when up, and the liquid level of cleaning solution will be less than the air vent, and when this robot of upset corresponds the part that the first wall was kept away from to ventilative pipe 120 to second wall 112 and up, the liquid level of cleaning solution still is less than the one end that the first wall was kept away from to the ventilative pipe, promptly: in both cases, the cleaning robot does not leak liquid. Therefore, the cleaning robot provided by the embodiment of the invention can improve the overflow condition of the cleaning liquid when the cleaning robot is overturned to a certain extent. In addition, even though the liquid storage chamber 114 is filled with the cleaning liquid, when the cleaning robot is turned over to the vent 1112 and faces upward, the liquid level of the cleaning liquid is lower than the vent, and when the robot is turned over to the second wall and faces upward to the portion of the vent 120 far away from the first wall, the cleaning liquid higher than the end of the vent 120 far away from the first wall will be kept stable under the effect of the atmospheric pressure and the friction resistance of the inner wall of the vent 120, i.e. the cleaning liquid will not overflow the liquid storage tank 100.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; within the idea of the invention, also technical features in the above embodiments or in different embodiments may be combined, steps may be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
