Referring to fig. 1 to 4, an embodiment of the present utility model provides a dust box 100, which includes a box body 10 and a cover body 30, wherein the box body 10 has a mounting opening F, and the cover body 30 covers the mounting opening F and includes an upper cover 31, a filtering member 33 and a pressing member 35. The pressing member 35 is assembled to the upper cover 31 with a filtering space G formed therebetween, and the filtering member 33 is installed in the filtering space G. The cover 30 is configured with an air passage G1 and an air outlet C communicating with the air passage G1, and the pressing member 35 can allow air flow to pass through itself and enter the filter 33, and the air flow filtered by the filter 33 is discharged through the air passage G1 and the air outlet C.

It should be understood that, to achieve its normal function, the case body 10 in the dust box 100 should be formed with a receiving chamber R and a dust inlet K communicating with the receiving chamber R, so that dust generated by sweeping the floor machine can enter through the dust inlet K and be received in the receiving chamber R. The mounting opening F is also communicated with the accommodating cavity R, so that the garbage inlet K and the air outlet C can form an inflow and outflow passage. When the dust box 100 is installed to the sweeper to work, the fan generates suction force, negative pressure is formed in the cover body 30 and the accommodating cavity R of the box body 10 through the air outlet C, the dust box 100 can suck air from the garbage inlet K, and at the moment, garbage is sucked together. The air with the garbage is blown to the pressing member 35, and under the action of the filtering member 33, the air can be filtered to enter the air passing channel G1 in the cover body 30 and finally discharged from the air outlet C, and the garbage is screened out and left in the accommodating cavity R of the box body 10.

The filter 33 may be HEPA, and the assembly between the upper cover 31 and the pressing member 35 may be performed by means of clamping, bonding, screw connection, etc., which is not limited herein. The pressing member 35 should be hollow or mesh-like in at least a part of the area thereof in order to allow the air flow to pass therethrough.

In the dust box 100, the upper cover 31 is assembled with the pressing member 35 to accommodate the filter 33 therebetween, and the three are integrally formed into the cover 30. The integrated cover 30 is no longer a simple structural component, but it also serves the functions of filtering air and guiding air flow. Overall, the dust box 100 is integrally simplified into two main parts of the box body 10 and the cover body 30, and has simple structure and connection relation, and is convenient for assembly and subsequent use and maintenance.

Further, a filtering space G between a surface of the filter 33 facing away from the pressing member 35 and the upper cover 31 is configured as an air passage G1. In this manner, the air flow can sufficiently pass through the filter member 33 to be filtered thereby and then enter the air passing passage G1, and then be discharged.

To form this gas passage G1, the surface of the filter member 33 facing away from the pressing member 35 should be spaced from at least a part of the inner surface of the upper cover 31 by a structural support structure, or the upper cover 31 may be bulged and formed with a mounting table on the peripheral side, the filter member 33 being clamped between the pressing member 35 and the mounting table so as to be spaced from the other inner surface of the upper cover 31, or the filter member 33 being in a connection relationship with the pressing member 35 so as to be spaced from the other inner surface of the upper cover 31 by the pressing member 35, or the like.

Specifically, the case 10 includes a top plate 11, and the mounting opening F is formed in the top plate 11. The top plate 11 of the box body 10 is a structural plate positioned at the top of the box body 10 in a normal working state. When the blower stops working and loses suction, part of garbage can be separated from the surface of the filter element 33 under the action of gravity and returns to the accommodating cavity R.

In addition, after the cover body 30 is covered on the box body 10, the surface of the cover body 30 is flush with the surface of the box body 10, that is, the cover body 30 is covered on the box body 10 in a jogged mode, so that the surface consistency of the dust box 100 is strong.

Referring to fig. 5, in some embodiments, a glue storage position J is formed on a surface of the pressing member 35 facing the filter member 33, and the glue storage position J is used for gluing to adhere and press the filter member 33. The glue storage position J can be a gap naturally formed between the surface of the pressing piece 35 and the filtering piece 33, or can be a groove position formed on the pressing piece 35.

On the one hand, the filter element 33 can be fastened by the compression element 35, and this fastening is enhanced by the increased adhesion of the compression force to the glue. On the other hand, the gap between the pressing piece 35 and the filtering piece 33 can be filled by glue, so that the air tightness between the pressing piece 35 and the filtering piece 33 is enhanced, and air leakage is avoided.

Further, the pressing member 35 has a mesh window shape having a plurality of windows, and the filter member 33 entirely covers the plurality of windows. The louver-like press 35 can provide sufficient support while retaining a large air flow path for the filter element 33.

Referring to fig. 6 and 7 together, in the first embodiment, a rotating shaft 311 is configured at one end of the cover 30, a shaft slot 13 with an opening is formed at a side of the mounting opening F corresponding to the rotating shaft 311, and the rotating shaft 311 is detachably accommodated in the shaft slot 13 through the opening.

After the cover 30 is rotated around the rotation axis 311 to be closed, the first buckle 313 and the second buckle 15 can be engaged with each other to form a stable engagement relationship, so as to prevent the cover 30 from being opened and closed at will. Specifically, the rotating shaft 311 and the first buckle 313 are respectively configured at two ends of the upper cover 31, wherein the rotating shaft 311 is located at one end far from the air outlet C.

Referring to fig. 8 to 11, in the second embodiment, the opposite ends of the cover 30 are both configured with a first buckle 313, and the corresponding positions of the mounting opening F and the first buckle 313 are both configured with a second buckle 15 that mates with the first buckle 313.

The cover 30 can be first engaged with the second buckle 15 at the mounting opening F through the first buckle 313 at one end, and the first buckle 313 at the other end and the second buckle 15 at the other end can be engaged by rotating the cover 30 with the end as the rotating shaft 311, or the first buckle 313 at both ends and the second buckle 15 can be engaged at the same time.

In some embodiments, the dust box 100 further includes a sealing member 50, where the sealing member 50 is disposed on a side of the cover 30 facing the mounting opening F, for sealing the junction of the cover 30 and the box 10. The seal 50 may alternatively be connected to the case 10 or the cover 30.

The seal 50 provides a reliable seal between the cover 30 and the case 10 to prevent air leakage. The sealing member 50 may surround the entire mounting opening F and be deformed after the cover 30 is covered on the case 10 to secure the sealing effect.

In some embodiments, a dust discharge port 17 is formed on one side of the box body 10 for controlling the opening and closing. The dust discharge port 17 is closed when the sweeper sweeps the floor and is opened when the dust box 100 is cleaned. Besides manual cleaning, the floor sweeping machine can be provided with a base station, and the base station can regularly or quantitatively suck dust in the box body 10 by opening the dust discharging port 17 to automatically clean.

In the dust box 100, the cover 30 is formed by integrating the pressing member 35, the filtering member 33 and the upper cover 31, the filtering member 33 is fixed between the pressing member 35 and the upper cover 31 in a net shape, and the filtering member 33 is further pressed and fixed by applying glue to the glue storage position J on the surface of the pressing member 35.
