Currently, with the improvement of living standard, more and more consumers choose to use machines to finish tedious housework, wherein an intelligent sweeping robot is favored by the consumers. The water tank and the dust box of the sweeping robot with the wet mopping function are combined into a whole in a common mode, the water tank and the dust box are connected in a clamping, threaded connection, riveting and other modes, and the water tank is generally of a three-layer structure and comprises a bottom shell, a middle shell and an upper cover which are sequentially stacked in the thickness direction, the middle shell separates a space enclosed by the bottom shell and the upper cover to form an upper cavity and a lower cavity which are arranged up and down, the upper cavity is used for setting an electric element, and the lower cavity is used for storing clear water. However, the process and manner of connection of the middle case with the bottom case and the upper cover results in a complex overall structure of the water tank and a long manufacturing time.

In view of this, the embodiment of the present application provides a water tank structure, wherein, the water tank lower shell of the bottom shell can form a water storage tank and an electric tank which are separated from each other, and the water storage cavity and the electric cavity are formed when the water tank upper cover is covered with the water tank lower shell. Compared with the space of the water tank structure in the longitudinal direction, the space of the water tank structure in the transverse direction can reduce the use of the middle shell, the connecting process between the lower water tank shell and the upper water tank cover is simpler, and the steps of the connecting process between the lower water tank shell and the upper water tank cover are fewer, so that the manufacturing difficulty of the water tank structure is reduced.

Referring to fig. 1, in a first aspect, the present application provides a water tank structure 100, including a bottom case 10 and a water tank upper cover 20.

The bottom case 10 includes a lower case 11, and a water storage tank 11a and an electric tank 11b are formed in the lower case 11 to be separated from each other. Wherein the water storage tank 11a and the electric tank 11b are not directly communicated, so as to prevent the water in the water storage tank 11a from flowing into the electric tank 11 b; alternatively, the reservoir 11a and the electrical tank 11b may be in spatial communication, and water in the reservoir may not be allowed to enter the electrical tank directly. The electric groove 11b is used for placing corresponding electric components such as an air pump, an electrode sheet, a circuit board, and the like.

The upper tank cover 20 covers the lower tank case 11 so that the water storage tank 11a and the electric tank 11b form a relatively independent water storage chamber and electric chamber. The connection mode of the upper tank cover 20 and the lower tank case 11 includes, but is not limited to, clamping, plugging, threaded connection, etc. And the relative independence of the water storage cavity and the electric cavity means that the water storage cavity and the electric cavity are selectively communicated under the condition that the normal working state of the electric element is not affected, for example, an air pump in the electric cavity is required to pump the water storage cavity so as to achieve the purpose of rapid water outlet.

Illustratively, a partition structure is disposed in the lower tank case 11 to divide the space of the lower tank case 11 into a water storage tank 11a and an electric tank 11b which are arranged transversely, and then, after the upper tank cover 20 is covered with the lower tank case 11, the partition structure is abutted against the inner wall of the upper tank cover 20 to form a water storage cavity and an electric cavity which are not communicated with each other.

Or, the upper water tank cover 20 also has a certain accommodating space, the inner wall of the upper water tank cover 20 is also provided with a partition structure, and when the upper water tank cover 20 is buckled with the lower water tank shell 11, the partition structure of the upper water tank cover 20 is abutted with the partition structure of the lower water tank shell 11 so as to form a water storage cavity and an electric cavity which are not communicated with each other.

The water tank structure 100 provided by the application forms the water storage tank 11a and the electric tank 11b by separating the inner space of the lower water tank shell 11 of the bottom shell 10, and each tank forms a relatively independent water storage cavity and an electric cavity when the upper water tank cover 20 and the lower water tank shell 11 are covered. Thus, the whole water tank structure 100 is only enclosed by two structures which are buckled up and down to form a space required by water storage and a space required by electric placement, the whole structure is simple, and the water tank structure is only required to be sealed at the joint of the two structures, so that the number of working procedures is small.

Referring to fig. 1 and 3, in some embodiments, a partition plate 111 is disposed in the lower tank case 11, the partition plate 111 is used to partition the inner space of the lower tank case 11 into a water storage tank 11a and an electric tank 11b, and one end of the partition plate 111 away from the lower tank case 11 is connected with the upper tank cover 20 in a sealing manner.

It will be appreciated that the sealing connection may be by gluing, i.e. by gluing, between the end of the partition 111 and the inner wall of the tank top 20; a sealing structure may be provided between the end of the partition plate 111 and the inner wall of the tank cover 20 to perform a sealing connection; alternatively, both the adhesive application and the sealing structure are provided between the end of the partition plate 111 and the inner wall of the tank cover 20.

And, the shape and structure of the partition plate 111 are not limited, for example, the partition plate 111 includes but is not limited to a straight plate, an arc plate, a deformed plate, etc., and the groove profile of the water storage tank 11a and the groove profile of the electric tank 11b are not limited, so as to meet the actual use requirement.

Alternatively, an abutting plate corresponding to the partition plate 111 may be disposed on the inner wall of the tank upper cover 20, where the abutting plate belongs to an outward extending portion of the inner wall of the tank upper cover 20, and sealing connection is performed between the partition plate 111 and the abutting plate, so that sealing difficulty between the tank upper cover 20 and the tank lower case 11 can be reduced. Specifically, when the tank upper cover 20 is engaged with the tank lower case 11, one end of the partition plate 111 away from the tank lower case 11 abuts against one end of the abutting plate away from the tank upper cover 20 to perform sealing connection.

Specifically, referring to the drawings, in some embodiments, a recess 111a is formed at an end of the partition plate 111, and a protrusion (not shown) is formed on the tank top cover 20, where the recess 111a is adapted to the protrusion to realize a sealing connection.

It will be appreciated that the recess 111a includes, but is not limited to, a groove, a blind hole, a pit, etc.; the protrusions include, but are not limited to, bumps, posts, ribs, and the like. The sealing connection with the convex portion may be made by directly dispensing in the concave portion 111a, or the sealing connection with the convex portion may be made indirectly by providing a seal at the concave portion 111a, or the dispensing may be made in the concave portion 111a, and at the same time, a sealing structure may be provided on the convex portion, and the sealing connection with the concave portion 111a may be made by using the sealing structure on the convex portion.

Alternatively, the concave portion 111a and the convex portion may be exchanged between the end of the partition plate 111 and the inner wall of the tank top cover 20, or both the concave portion 111a and the convex portion may be provided on the end of the partition plate 111, and similarly, the corresponding convex portion and concave portion 111a may be provided at the corresponding position of the tank top cover 20 for fitting.

Referring to fig. 1 and 2, in some embodiments, the water tank structure 100 further includes an air pump assembly 30, and the water tank upper cover 20 is recessed inward to form an air pump cavity 20a accommodating the air pump assembly 30.

Here, the air pump assembly 30 is used for pumping the water storage cavity so that the water storage cavity is pressurized, and the water stored in the water storage cavity is sprayed on the mop to meet the requirement that the cleaning robot performs wet mopping on the floor to be cleaned.

Meanwhile, the air pump chamber 20a is located on the upper tank cover 20, so that when the air pump assembly 30 is maintained or assembled, it can be performed with the upper tank cover 20 and the lower tank case 11 being covered, further reducing the maintenance and assembly processes.

Alternatively, in order to enhance the tightness of the air pump chamber 20a, a cover plate may be provided at the open end of the air pump chamber 20a. Thus, the opening or closing of the air pump chamber 20a can be realized by opening or closing the cover plate, so that the air pump assembly 30 can be maintained at a later period.

Referring to fig. 2, in a specific embodiment, the air pump assembly 30 includes a pump body 31 and a conduit 32 connected to the pump body 31, the air pump cavity 20a includes a first cavity 20a1 and a second cavity 20a2, which are connected to each other, the first cavity 20a1 corresponds to the electric tank 11b, the second cavity 20a2 corresponds to the water storage tank 11a, the pump body 31 is disposed in the first cavity 20a1, and the conduit 32 is disposed in the second cavity 20a2 and extends into the water storage tank 11a.

It can be appreciated that the first chamber 20a1 is sunk into the electric tank 11b, so that the thickness of the upper cover 20 and the lower shell 11 in the fastened state can be reduced, and further space is saved.

And, similarly, the second chamber 20a2 sinks into the water storage tank 11a, which can achieve the purpose of saving space. In addition, the air pump cavity 20a is divided into the first cavity 20a1 and the second cavity 20a2, so that the damage caused by reverse osmosis of the water stored in the water storage cavity can be reduced, namely, if the reverse osmosis phenomenon occurs in the water stored in the second cavity 20a2, the probability that the water stored directly enters the first cavity 20a1 is reduced, and the normal operation of the pump body 31 is affected, and meanwhile, a user only needs to clean the second cavity 20a2 regularly. Therefore, the first chamber 20a1 and the second chamber 20a2 are distributed on opposite sides of the partition plate 111 in terms of spatial distribution when the tank upper cover 20 is covered with the tank lower case 11.

The working process of the air pump assembly 30 in the air pump cavity 20a is as follows: the pump body 31 in the first chamber 20a1 is controlled to start, a pressure difference is formed, and the water storage cavity is pressurized through the conduit 32 in the second chamber 20a2, so that the water storage discharge rate in the water storage cavity is increased.

Referring to fig. 7, in some embodiments, an air intake hole structure 20c is formed on an inner wall of the first chamber 20a 1.

It will be appreciated that the air pump assembly 30 is essentially operated by creating a pressure difference, and the air in the first chamber 20a1 needs to be discharged into the water storage tank 11a, so that in order to ensure that the air pressure of the first chamber 20a1 is normal, an air inlet structure 20c communicating with the outside needs to be formed on the inner wall of the first chamber 20a 1.

Here, the shape of the air intake hole structure 20c includes, but is not limited to, circular holes, square holes, and bar-shaped holes, and the number of the air intake hole structures 20c may be one, two, and plural.

Optionally, an air inlet hole structure 20c is formed on the bottom wall of the first chamber 20a1, where the bottom wall of the first chamber 20a1 refers to the inner wall of the upper cover 20 of the water tank facing the lower shell 11 of the water tank, and the bottom wall is far away from the open end of the first chamber 20a1, so that the condensation of water vapor on the cover plate forming the open end of the air pump chamber 20a can be reduced, and the appearance of the product is further improved.

Referring to fig. 2, in some embodiments, the air pump assembly 30 further includes a sealing member 33 sleeved on the pump body 31, the sealing member 33 is provided with a shock absorbing structure 34, and the pump body 31 is in interference fit with the inner wall of the first chamber 20a1 through the shock absorbing structure 34.

It can be appreciated that the sealing member 33 is wrapped or sleeved on the pump body 31 to cover the pump body 31, so as to improve the overall waterproof performance of the pump body 31. Here, the structural form of the seal member 33 is not limited, so long as it can satisfy the sealing of the pump body 31.

And, the water tank structure 100 mounted on the cleaning robot body may vibrate as the cleaning robot moves, so in order to improve the mounting stability of the pump body 31 in the first chamber 20a1, a shock absorbing structure 34 is formed on the sealing member 33, where the connection relationship between the sealing member 33 and the shock absorbing structure 34 includes, but is not limited to, integral molding, plugging, clamping, screwing, etc., and the shock absorbing structure 34 is in interference fit with the inner wall of the first chamber 20a1, so as to reduce the probability of the relative movement of the pump body 31 in the first chamber 20a 1.

Illustratively, the shock absorbing structure 34 includes ribs or bead sites integrally formed on the seal 33 and may be provided on each side of the seal 33 depending on the shock absorbing requirements.

Referring to fig. 1, in some embodiments, the water tank structure 100 includes a control board 40 and a recharging pole piece assembly 50, the air pump assembly 30 and the recharging pole piece assembly 50 are electrically connected to the control board 40, and the recharging pole piece assembly 50 and the control board 40 are respectively clamped on the water tank upper cover 20.

It is understood that the control board 40 may be electrically connected to a main control circuit board of the cleaning robot, for outputting corresponding instructions to the air pump assembly 30, for example, controlling the air pump assembly 30 to be turned on or off, and delaying the turning on or off.

The recharging pole piece assembly 50 is used for being in butt joint with the positive pole and the negative pole of an external power supply so as to meet the requirement of charging the cleaning robot. Meanwhile, the control board 40 can also control the on-off state of the recharging pole piece assembly 50 and the external power supply.

The recharging pole piece assembly 50 and the control board 40 are connected to the tank top cover 20 by a snap-fit connection. Specifically, a clamping hole is formed in the upper water tank cover 20, the recharging pole piece assembly 50 is clamped in the clamping hole through a clamping arm, and a clamping groove is formed in the upper water tank cover 20, and the control board 40 is directly clamped in the clamping groove.

For example, two adjacent clamping holes are formed on the side wall of the upper cover 20 of the water tank, and meanwhile, the two recharging pole piece assemblies 50 are clamped in the corresponding clamping holes, so that the two recharging pole piece assemblies 50 are convenient to dock with the positive pole and the negative pole of the external power supply respectively, so as to obtain corresponding charging requirements.

Meanwhile, a clamping groove is formed in the side wall of the upper water tank cover 20 and is communicated with the first chamber 20a1, so that the control board 40 can be clamped in the clamping groove and is adjacent to the air pump assembly 30 in the first chamber 20a1, and the electric connection distance between the control board 40 and the air pump assembly 30 is shortened.

Referring to fig. 4, in some embodiments, the inner wall of the upper cover 20 of the water tank forms a wiring groove 20d for wiring the recharging pole piece assembly 50, and the wiring groove 20d corresponds to and encloses the electrical groove 11b to form an electrical cavity.

It will be appreciated that the wiring groove 20d formed on the inner wall of the tank cover 20 can further increase the space of the electric chamber, and at the same time, the wiring distribution is clearer, which is convenient for subsequent maintenance.

For example, the control board 40 is clamped on the upper cover 20 and is adjacent to the first chamber 20a, and the wiring groove 20d extends to the first chamber 20a, so as to satisfy the condition that the recharging plate assembly 50 is electrically connected to the control board 40 through the wiring.

Optionally, in order to further classify and constrain the cables in the wiring groove 20d, a wire clamping structure may be disposed on the inner wall of the wiring groove 20d, and the number and the disposition positions of the wire clamping structure may be set according to the number and the distribution of the wires.

Referring to fig. 4, in some embodiments, the recharging pole assembly 50 includes a pole piece bracket 51 and a pole piece body 52 clamped on the pole piece bracket 51, and the pole piece bracket 51 is clamped on the water tank upper cover 20.

Here, in the conventional connection process, the recharging pole piece is welded on the upper cover 20 of the water tank, although the stability is higher, the installation and maintenance are not facilitated, and therefore, the connection relationship between the pole piece support 51 and the upper cover 20 of the water tank in the recharging pole piece assembly 50 and the connection relationship between the pole piece body 52 and the pole piece support 51 are both detachable, so that when the pole piece body 52 breaks down and needs to be detached, the pole piece support 51 can be replaced, and likewise, the pole piece support 51 needs to be detached from the upper cover 20 of the water tank more conveniently.
