Example 1

The present embodiment provides a water tank assembly 100. The water tank assembly 100 may be used in a cleaning device, such as a floor scrubber. Referring to fig. 1 to 3, the water tank assembly 100 includes a tank structure 10, a tank cover structure 20, and a filtering structure 30. The box structure 10 includes a housing 11 and a liquid inlet pipe 12, at least part of the liquid inlet pipe 12 can be located in the housing 11, and the liquid inlet pipe 12 can be communicated with the interior of the housing 11 and the outside. Referring to fig. 4, the housing 11 may have a receiving cavity 13 therein, the liquid inlet tube 12 may be disposed in the receiving cavity 13, the liquid outlet end 121 of the liquid inlet tube 12 may be connected to the receiving cavity 13, and the liquid inlet end 122 of the liquid inlet tube 12 may be connected to the housing 11 and connected to the outside.

It will be appreciated that in some embodiments, the inlet end 122 of the inlet tube 12 may also be disposed in a protruding manner relative to the housing 11.

In this way, the liquid inlet pipe 12 can be used for allowing the solid-liquid mixture to enter the containing cavity 13. Specifically, the external solid-liquid mixture can enter the liquid inlet pipe 12 through the liquid inlet end 122, and then flows out of the liquid outlet end 121 of the liquid inlet pipe 12 and enters the containing cavity 13.

The cover structure 20 is detachably connected to the housing 11, in other words, the cover structure 20 is detachably mounted at the opening of the accommodating cavity 13, and the cover structure 20 may be mounted at the opening of the accommodating cavity 13 by a fastener assembly, or the cover structure 20 may be mounted at the opening of the accommodating cavity 13 by a fastener such as a bolt.

In addition, the filter structure 30 is fastened to the case cover structure 20, for example, the filter structure 30 and the case cover structure 20 may be connected together by a fastening assembly or a bolt. When the lid structure 20 and the case structure 10 are coupled together, the filter structure 30 may be located within the receiving cavity 13 or outside the receiving cavity 13. The specific installation location for the filter structure 30 may be determined according to practical circumstances.

The operation of the water tank assembly 100 will be described with reference to the specific embodiment shown in fig. 4, taking the above-described application of the water tank assembly 100 to a floor washing machine as an example.

When the floor scrubber cleans a surface to be cleaned, the solid-liquid mixture of the surface to be cleaned may enter the liquid inlet pipe 12 through the liquid inlet end 122 and then flow from the liquid outlet end 121 into the receiving chamber 13 of the housing 11. At this time, the case structure 10 and the cover structure 20 are in a connected state (as shown in fig. 2). When the solid-liquid mixture stored in the receiving chamber 13 reaches a threshold value, the water tank assembly 100 may be first removed from the floor scrubber. The lid structure 20 and the box structure 10 may then be separated (as shown in fig. 3), and the position between the lid structure 20 and the box structure 10 may then be adjusted, and the solid-liquid mixture may fall into the filter structure 30 when pouring the solid-liquid mixture in the receiving chamber 13.

In this way, the solid waste can stay in the filtering structure 30, and the liquid waste can pass through the filtering structure 30 and enter the waste water bucket below the filtering structure 30, so that the solid-liquid separation of the solid-liquid mixture is realized. After the solid-liquid mixture in the receiving chamber 13 is poured, the solid waste material in the filter structure 30 may be poured into a trash can or a recycling member. Because the filter structure 30 is removably connected to the lid structure 20, the filter structure 30 can be removed from the lid structure 20 and cleaned.

To sum up, when solid-liquid separation is required for the solid-liquid mixture in the water tank assembly 100, the tank structure 10 and the tank cover structure 20 can be separated, so that the solid-liquid mixture can fall into the filtering structure 30 through the opening of the accommodating cavity 13, and the solid-liquid separation is performed by using the filtering structure 30. After the solid-liquid separation is completed, the filtering structure 30 can be removed from the case cover structure 20 and cleaned, so that the probability of residual dirt on the filtering structure 30 is reduced, and the difficulty in cleaning the filtering structure 30 is reduced.

In some embodiments, as shown in fig. 3, the lid structure 20 includes a mounting portion 24. The mounting portion 24 may be located within the housing 11. Referring to fig. 5, in the direction from the case cover structure 20 to the case body structure 10, the mounting portion 24 is provided with at least two first engaging portions 241. All the first clamping portions 241 are arranged at intervals around the circumference of the mounting portion 24, and at least one of the first clamping portions 241 is clamped with the filter structure 30.

When the filter structure 30 is engaged with the first engaging portion 241 located at a different position, the position of the filter structure 30 relative to the mounting portion 24 is different. For example, in the example shown in fig. 6, the filter structure 30 and the mounting portion 24 are located on either side of the inlet tube 12, respectively. In the example shown in fig. 7 and 8, both the filter structure 30 and the mounting portion 24 are located on one side of the inlet tube 12. By the arrangement, the filter structure 30 can be conveniently installed at the corresponding position of the installation part 24 by a user according to the operation of the user's own habit, and the installation flexibility of the filter structure 30 is improved. Thereby facilitating the removal of the water tank assembly 100 by a user and pouring of the solid-liquid mixture within the tank structure 10.

Specifically, as shown in fig. 9 and 10, in some embodiments, the filter structure 30 may include a body 31 and a second snap 32. The body 31 is provided with a plurality of filtering through holes 311 distributed at intervals, and the second clamping portion 32 can be mounted on the body 31 and clamped with the first clamping portion 241.

When the filtering structure 30 is located in the accommodating cavity 13, and the solid-liquid mixture is stored in the accommodating cavity 13, if the water tank assembly 100 collides to cause the solid-liquid mixture to shake to form a surge, the filtering structure 30 can shield the surge, so that the probability that the viscous waste in the solid-liquid mixture is attached to the inner wall of the shell 11 under the action of inertia, that is, the probability of the inner wall of the accommodating cavity 13 is reduced, and the difficulty of cleaning the inner wall of the shell 11 by a user is reduced.

When the filtering structure 30 is used for separating a solid-liquid mixture, liquid waste may flow into the waste water bucket through the filtering through holes 311, and the solid waste with a larger volume may be blocked by the filtering through holes 311 and stay on the filtering structure 30. By the arrangement, the structure of the filter structure 30 is simplified, the production and processing difficulty of the filter structure 30 is reduced, and the filter structure 30 is easy to obtain.

The number of the second clamping portions 32 may be plural, and one of all the second clamping portions 32 may be clamped with the first clamping portion 241.

Because the filtering structure 30 can be divided into two parts of the body 31 and the second clamping portion 32, when one of the second clamping portions 32 is damaged, the other second clamping portions 32 can be clamped with the first clamping portion 241, so that the filtering structure 30 and the box cover structure 20 are connected. Thus, not only the maintenance cost of the filter structure 30 can be reduced, but also the service life of the filter structure 30 can be prolonged.

With continued reference to fig. 10, in some examples, the second engaging portion 32 may be a bump formed by protruding with respect to the body 31. As shown in fig. 11, the first engaging portion 241 is a slot engaged with the bump;

in other examples, the second clamping portion 32 is a groove recessed relative to the body 31, and the first clamping portion 241 is a clamping block clamped with the groove.

One of the first clamping portion 241 and the second clamping portion 32 is similar to the groove in structure, and the other is a clamping block, so that the structures of the first clamping portion 241 and the second clamping portion 32 can be simplified, and the first clamping portion 241 and the second clamping portion 32 can be easily manufactured.

More specifically, with continued reference to fig. 9 and 10, the filter structure 30 further includes a shielding portion 33. The shielding portion 33 and the second clamping portion 32 are respectively located at two sides of the body 31, the shielding portion 33 can form a surrounding structure around the edge of the body 31, and are arranged in a protruding manner relative to the body 31, and an accommodating space can be formed between the shielding portion 33 and the body 31.

When the filtering structure 30 is used for separating a solid-liquid mixture, the shielding portion 33 may be disposed toward the liquid outlet end 121. So that the solid-liquid mixture flowing out from the liquid outlet end 121 can fall entirely into the accommodating space. In this way, the main body 31 and the shielding portion 33 can block the solid-liquid mixture falling onto the surface of the filtering structure 30, and the accommodating space is used to accommodate the solid waste in the solid-liquid mixture, so as to reduce the probability that the solid-liquid mixture flows along the surface of the filtering structure 30 to the cover 21 and other components.

In some embodiments, as shown in fig. 10, the body 31 may extend along the lid structure 20 in the direction of the box structure 10. The middle area of the body 31 is recessed relative to the rest areas to form a protruding section, the protruding section can be recessed towards the direction of the shielding part 33, and the recessed shape of the protruding section is matched with the shape of the outer wall of the liquid inlet pipe 12.

For example, when the outer wall of the inlet tube 12 is square. The outer wall body of the protruding section can be square, and the protruding section and the outer wall body can be completely attached. By this arrangement, the contact area between the body 31 and the inlet pipe 12 can be increased, thereby improving the mounting stability therebetween.

For example, with continued reference to fig. 10, the concave shape of the protruding section may be arc-shaped, and the distance between the protruding apex of the protruding section and the second engaging portion 32 in the direction perpendicular to the plane of the body 31 is smaller than the distance between the free end of the shielding portion 33 and the second engaging portion 32.

Thus, after the solid-liquid mixture falls into the receiving space of the filtering structure 30, it can move along the protruding section of the body 31 toward the remaining area of the body 31. Since the protruding apex of the protruding section is lower than the free end of the shielding portion 33, when the solid-liquid mixture impinges on the body 31 to cause sputtering, the shielding portion 33 shields a part of the sputtered solid-liquid mixture, thereby reducing the probability of the solid-liquid mixture flowing into the remaining parts.

As shown in fig. 3 and 4, the cover structure 20 further includes a cover 21 and a shutter 22 that are detachably connected. Wherein, the cover body 21 can be detachably arranged at the opening of the accommodating cavity 13 and is provided with an air outlet channel 23 communicated with the accommodating cavity 13. The shielding member 22 is provided with a mounting portion 24, and the shielding member 22 is mountable to the side of the air outlet passage 23 adjacent to the housing 11 and positioned in the accommodation chamber 13. Wherein the shield 22 may be positioned between the outlet channel 23 and the outlet end 121 and shield at least a portion of the outlet end 121 adjacent to the outlet channel 23.

In some examples, the shield 22 may be mounted beside the outlet channel 23 on the side of the outlet end 121 of the inlet tube 12 facing the cover 21. The shielding member 22 and the liquid outlet end 121 have a certain interval therebetween so that the solid-liquid mixture can smoothly enter the accommodating cavity 13, especially the solid waste with larger volume in the solid-liquid mixture.

The shielding member 22 can shield a part of the liquid outlet end 121 near the gas outlet channel 23, i.e. block the solid-liquid mixture flowing out of the liquid outlet end 121 and change the flow direction thereof, so that the solid-liquid mixture can flow to the gas outlet channel 23 only by bypassing the shielding member 22 for blocking the solid-liquid mixture.

After the solid-liquid mixture enters the accommodating chamber 13, the solid-liquid mixture and the gas in the accommodating chamber 13 can flow out of the water tank assembly 100 through the gas outlet channel 23. The shielding member 22 is arranged near the liquid outlet end 121 to change the flow direction of the solid-liquid mixture, so that the probability that the solid waste and the liquid waste in the solid-liquid mixture enter the air outlet channel 23 and enter the inside of the floor scrubber and other devices along the air outlet channel 23 and have adverse effects on the solid waste and the liquid waste can be reduced.

In other examples, the dimensions of the shield 22 may be adapted to the dimensions of the outlet channel 23. It will also be appreciated that the shield 22 shields both the outlet end 121 and part of the outlet channel 23.

Illustratively, as shown in FIG. 4, a shield 22 may be mounted at the outlet channel 23. The size of the shielding member 22 is adapted to the opening size of the air outlet channel 23, and the shielding member 22 is provided with an air outlet through hole 221 communicating the air outlet channel 23 with the accommodating chamber 13, and the size of the air outlet through hole 221 may be smaller than the opening size of the air outlet channel 23.

After the solid-liquid mixture enters the accommodating chamber 13, the solid-liquid mixture and the gas in the accommodating chamber 13 can be discharged out of the water tank assembly 100 through the gas outlet through hole 221 and the gas outlet channel 23 in sequence. The vent hole 221 is formed in the shielding member 22, and the size of the shielding member 22 is set to be matched with the opening size of the vent channel 23, so that the connection stability between the shielding member 22 and the cover body 21 can be improved on the basis that the gas discharge in the accommodating cavity 13 is not influenced.

In addition, the tank assembly 100 collides with the solid-liquid mixture in the receiving chamber 13 to easily shake and surge. Shielding part of the opening of the air outlet channel 23 can reduce the probability that liquid waste and the like enter the air outlet channel 23 under the action of inertia, so that the liquid waste enters the inside of the device such as the floor scrubber and the like along the air outlet channel 23, and the inside of the floor scrubber and the like is caused to be water-in.

As shown in fig. 5, the shield 22 may include an interconnecting connecting portion 222 and a protruding portion 223. The connection portion 222 is further connected with a mounting portion 24, and the mounting portion 24 may be disposed on the same side as the protruding portion 223. The connection portion 222 is provided with an air outlet through hole 221, and the protrusion 223 may be located between the air outlet through hole 221 and the liquid outlet end 121 of the liquid inlet pipe 12.

The liquid outlet 121 may be located at a side of the protrusion 223 facing away from the air outlet 221, and the front projection of the liquid outlet 121 on the housing 11 is located in the front projection of the protrusion 223 on the housing 11 in a direction perpendicular to the direction from the case cover structure 20 to the case body structure 10. In other words, at least a portion of the area of the outlet end 121 near the outlet through hole 221 can be blocked by the protrusion 223.

By doing so, not only is the structure of the shade 22 simplified, but also the effect of the shade 22 on the side from the outlet port 121 near the outlet through hole 221 is improved.

In some examples, as shown in fig. 6, the filtering structure 30 may be located at a side of the protrusion 223 away from the air outlet hole 221, and the filtering structure 30, the protrusion 223 and the connection portion 222 together form a containing space, and the liquid outlet 121 is located in the containing space.

When the solid-liquid mixture flows out from the liquid outlet end 121, the viscous waste such as hair may be washed over the filter structure 30 first, may stay in the filter structure 30, and the waste that cannot adhere or has a large weight may fall into the liquid waste under its own weight. The above arrangement can reduce the adhesion of viscous waste to the inner wall of the accommodating chamber 13, that is, the total amount of the inner wall of the housing 11, thereby reducing the difficulty of cleaning the inner wall of the housing 11 for a user.

In other examples, as shown in FIG. 7, both the filter structure 30 and the projection 223 may be located on the same side of the inlet tube 12. Wherein the filter structure 30 is arranged close to the bottom of the housing 11 with respect to the protrusion 223. When the housing 11, i.e. the receiving chamber 13, stores a certain amount of solid-liquid mixture, part or all of the filter structure 30 is immersed in the liquid waste. Thus, the smoothness of the surface of the filter structure 30 can be improved, and the probability that stubborn stains adhere to the filter structure 30 and are difficult to clean can be reduced.

Next, when the filter structure 30 and the protrusion 223 are both located on the same side of the inlet pipe 12, the shielding portion 33 of the filter structure 30 and the outlet through hole 221 are also located on the same side of the inlet pipe 12.

In this case, as shown in fig. 8, if the solid-liquid mixture shakes in the accommodating chamber 13, the shielding portion 33 of the filtering structure 30 may block the solid-liquid mixture to reduce the probability of the solid-liquid mixture entering the air outlet through hole 221 under the inertia effect.

As shown in fig. 8, the liquid inlet end 122 of the liquid inlet pipe 12 is located on the side of the housing 11 facing the opening of the accommodating chamber 13, and the liquid inlet pipe 12 is disposed obliquely along the direction from the cover structure 20 to the case structure 10. In this way, in the process of pouring the solid-liquid mixture in the accommodating cavity 13 by the user, the smoothness of the solid-liquid mixture flowing out of the liquid inlet pipe 12 is improved, and the probability of the solid-liquid mixture remaining in the liquid inlet pipe 12 is reduced.
