In an application scenario, the tank structure is a sewage tank for a floor scrubber. Of course, the tank structure includes, but is not limited to, a waste tank of a floor scrubber, but may also be a waste tank on other cleaning equipment. The following will mainly describe the case where the tank structure is used as a sewage tank of a floor washing machine. It will be appreciated from the foregoing that the scope of embodiments of the utility model is not limited thereby.

Referring to fig. 1 to 3, the box structure includes: the tank body 150, the tank cover 160, the dirt inlet pipe 110, and the filter 200. The case body 150 is hollow in the inside and is provided with an opening at the top to form a hollow cavity. The cover 160 covers the top opening end of the case body 150 for closing the hollow cavity. The dirt inlet pipe 110 is disposed on the box body 150 and is used for introducing dirt into the hollow cavity of the box body 150, wherein the dirt is a mixture of solid, liquid and gas. The filter 200 is accommodated in the hollow cavity of the case body 150 to separate solid and liquid of dirt in the case body 150.

The detachable connection mode is adopted between the box body 150 and the box cover 160, when the dirt in the box body 150 is fully loaded, the box cover 160 can be taken down from the box body 150, the dirt in the box body 150 is emptied, and the use is very convenient.

In particular, referring to fig. 4 and 5, the case body 150 and the case cover 160 are detachably coupled by a locking assembly 400. The locking assembly 400 is disposed on the case cover 160, and a locking groove 140 matched with the locking assembly 400 is disposed at the top opening end of the case body 150.

The locking assembly 400 at least comprises a pair of locking tongues 420 disposed opposite to each other, an elastic member 430 abutting between the pair of locking tongues 420, and a pressing member 410 slidably disposed on the case cover 160 and abutting over the pair of locking tongues 420.

The locking assembly 400 has a locked state and an unlocked state. In the locked state, the pair of locking tongues 420 are inserted into the locking grooves 140 under the elastic force of the elastic member 430, and at this time, the case cover 160 cannot be removed from the case body 150, thereby realizing connection of the case cover 160 and the case body 150. When the dirt in the case body 150 needs to be poured, the pressing member 410 is pressed down, and the external force applied to the pressing member 410 can overcome the elastic force of the elastic member 430, so that the pair 420 of locking tongues are close to each other and separate from the locking groove 140, and at this time, the case cover 160 is separated from the case body 150, and the case cover 160 can be removed from the case body 150.

In the present embodiment, the dirt inlet pipe 110 is located at the outer side of the tank body 150, and the dirt inlet pipe 110 is a part of the outer wall of the tank body 150.

Considering that the filter 200 functions to perform solid-liquid separation, in order to facilitate removal of the filtered solid medium from the tank body 150, the filter 200 is detachably provided in the hollow cavity of the tank body 150.

Regarding the arrangement of the filter element 200, in the first arrangement, the filter element 200 is detachably disposed in the hollow cavity, and when the dirt is to be cleaned, the cover 160 is removed from the case body 150, and then the filter element 200 is removed from the hollow cavity.

In the second setting, referring to fig. 6, the filter 200 is disposed at the bottom of the case cover 160, and can be engaged with or disengaged from the case body 150 in synchronization with the case cover 160. The filter element 200 may be connected to the cover 160 by fasteners (bolts, screws), by snap-fit connection, or by other removable means. In the above case, when the cover 160 is removed, the filter 200 is simultaneously taken out along with the cover 160, and the solid medium is taken out of the case body 150 for the convenience of cleaning by the user.

The filter 200 has a filter area in which solid media in dirt is stored and liquid media in dirt drips down to an area below after passing through the filter area. In this embodiment, the dirt inlet tube 110 has an outflow opening 111 in the hollow cavity, the dirt inlet tube 110 and the outflow opening 111 being located outside the filter area. It should be noted that the filter member 200 has a moving path that is disposed away from the dirt inlet pipe 110, that is, the dirt inlet pipe 110 is not in the direction of attachment/detachment of the filter member 200, whereby the solid medium in the filtering area can be prevented from adhering to the dirt inlet pipe 110 during the process of lifting up the filter member 200.

In this embodiment, after the dirt inlet pipe 110 and the dirt outlet 111 are disposed outside the filtering area, on one hand, the space of the filtering area is not occupied, so that the filtering area can be expanded to accommodate more dirt, and frequent cleaning of the box body 150 is avoided; on the other hand, the filter element 200 is convenient to be taken out from the tank body 150, in the prior art, the middle upper part and the outflow opening of the dirt inlet pipe are positioned in the filtering area, the filtering area is distributed on the periphery of the dirt inlet pipe, in the above case, the solid medium accumulated in the filtering area is wrapped around the dirt inlet pipe 110, the difficulty of lifting the filter element 200 from the tank body 150 is increased, in addition, in the process of lifting the filter element 200, the solid medium in the filtering area is adhered to the outer wall of the dirt inlet pipe 110, and the cleaning is time-consuming and labor-consuming; in yet another aspect, the suction power of the scrubber is greatly affected when the dirt inlet pipe is located in the filtering area in the prior art.

In order to locate the dirt inlet pipe 110 and the outflow port 111 outside the filtering area, in the present embodiment, the hollow cavity of the tank body 150 is divided into a plurality of communicating chambers, and the outflow port 111 and the filter member 200 are respectively located in different chambers, thereby ensuring that the dirt inlet pipe 110 and the filtering area of the filter member 200 do not affect each other, and the dirt inlet pipe 110 is not located on the moving path of the filter member 200. The different chambers inside the case body 150 are communicated through the communication port 103, and dirt discharged through the outflow port 111 enters the filtering area of the filter 200 through the communication port 103 between the chambers.

Further, the number of chambers inside the tank body 150 is two, namely the separation chamber 101 and the storage chamber 102. The separation chamber 101 and the storage chamber 102 are adjacently distributed, and the separation chamber 101 is communicated with the storage chamber 102 through a communication port 103.

The outflow opening 111 is located at the bottom of the separation chamber 101 and communicates with the separation chamber 101 through a separation channel 120. In this embodiment, the separation chamber 101 is a cylindrical chamber, and the separation channel 120 is a spiral channel. The dirt is moved rotationally upwards about the central axis of the separating chamber 101 by the separating passages 120.

The filter member 200 is disposed in the storage chamber 102, and the filter member 200 divides the storage chamber 102 into an upper space and a lower space, wherein the filter area is disposed in the upper space, and the lower space is configured to store a liquid medium in dirt, thereby achieving the purpose of solid-liquid separation.

The communication opening 103 is provided in the circumferential chamber wall of the separating chamber 101, whereby dirt discharged from the outflow opening 111 enters the separating chamber 101 in a rotationally moving manner and then enters the filter area of the filter element 200 via the communication opening 103.

Referring to fig. 6 and 7, referring to the structure of the filter element 200, the filter element 200 at least includes a side filter plate 210 and a bottom filter plate 220, wherein an included angle is formed between the side filter plate 210 and the bottom filter plate 220, and filter holes are formed in the side filter plate 210 and the bottom filter plate 220, and the side filter plate 210 and the bottom filter plate 220 enclose the filter area. To ensure that the filter area has a sufficiently large receiving space, the angle between the side filter plates 210 and the bottom filter plate 220 is approximately a right angle.

In this embodiment, the side filter plates 210 include a first side filter plate 211 and a pair of second side filter plates 212 disposed on the first side filter plate 211, wherein the pair of second side filter plates 212 are fixedly disposed on a pair of edges of the first side filter plate 211 that are opposite to each other. The bottom filter plate 220 is fixedly arranged at the bottoms of the first lateral filter plate 211 and the second lateral filter plate 212.

To facilitate pouring of solid media in the filter area, the opposite side of the first side filter plate 211 is not provided with a face, and the opposite top of the bottom filter plate 220 is not provided with a face, which is used to create an open area for dirt pouring and cleaning of the filter element 200.

It is contemplated that during cleaning of the tank body 150, the filter element 200 needs to be lifted out of the tank body 150, and that when the filter element 200 is lifted upward, the solid media within the filter area will adhere to the lateral cavity walls of the storage cavity 102 due to the presence of the open area. In the present embodiment, the above problem is solved by providing an upward-tilting extension 221 at the edge of the bottom filter plate 220, the extension 221 serving to prevent the solid medium from adhering to the chamber wall during the upward pulling of the filter member 200.

Specifically, the extension 221 is in the form of a sheet, one side of the extension 221 is fixedly attached to the bottom filter plate 220, and the opposite side is in infinite proximity to, but not in contact with, the chamber wall of the storage chamber 102. Wherein the extension 221 and the bottom filter plate 220 are distributed at an obtuse angle. Referring to fig. 2, when the filter member 200 is lifted upward, the extension 221 is located upstream of the path of movement of the filter member 200, and is capable of scraping off the solid medium adhering to the wall of the storage chamber 102, thereby avoiding the user from cleaning the wall of the storage chamber 102.

In this embodiment, the case cover 160 is provided with an air outlet channel that communicates with the separation chamber 101, and the air medium in the dirt is discharged out of the case body 150 through the air outlet channel on the case cover 160 after entering the separation chamber 101. In order to prevent fine dirt in the separating chamber 101 from flowing out of the box body 150 along the airflow, a HEPA module 170 is arranged in the air outlet channel. The HEPA module 170 filters the airflow to prevent dirt (particularly moisture) from entering the motor in the tank body 150.

In order to further prevent the water vapor in the tank body 150 from entering the air outlet channel, a gas-liquid separation assembly 300 is further provided in the tank structure. Specifically, the air outlet channel is formed with an air inlet at the bottom of the case cover 160, and the air inlet is provided with the gas-liquid separation assembly 300. The gas-liquid separation assembly 300 is used for performing gas-liquid separation on the air flow to be entered into the air inlet, and reducing the water-gas content included in the air flow.

The gas-liquid separation assembly 300 includes a rotating member 310 rotatably disposed at the air inlet and disposed in the separation chamber 101, and a driving member 320 disposed on the case cover 160 for driving the rotating member 310 to rotate. Wherein, rotating member 310 is the separating basket, is equipped with a plurality of openings in the circumference of rotating member 310, and when rotating member 310 rotated, the air current in the separation chamber 101 got into the air-out passageway through the opening, and some water drops that the particle diameter is great are thrown away under the effect of centrifugal force.

In order to monitor the liquid level in the storage chamber 102, a liquid level detection assembly 600 is further provided in the tank structure. In this embodiment, referring to FIG. 4, a fluid level detection assembly 600 is configured to detect a fluid level within the storage chamber 102. The liquid level detecting assembly 600 is a generally cylindrical body and extends along the direction from the case cover 160 to the case body 150. When the liquid level in the storage chamber 102 reaches a maximum value, the liquid level detection assembly 600 sends a signal to alert a user to timely pour the liquid in the tank body 150.

In this embodiment, the box structure has a vertical state and a horizontal state, and fig. 1 and fig. 2 are schematic diagrams of the box structure in the vertical state, where the top, bottom, upper, lower, and other orientations referred to above are orientations of the box structure in the vertical state. Fig. 8 is a schematic diagram of the case structure in a horizontal state, when the case structure is in a horizontal state, the separation chamber 101 is located above the storage chamber 102, and the liquid medium and the solid medium in the storage chamber 102 cannot be discharged through the air outlet channel, so that the scrubber can be cleaned in a lying state.
