Fig. 1 is an exploded schematic view of a dust collection box according to an embodiment of the present disclosure, and fig. 2 is a schematic view of a blocking cover of the dust collection box according to the embodiment of the present disclosure in a first state.

As shown in fig. 1 and 2, the present embodiment provides a dust box 1 for a vacuum cleaner, particularly a dust collector for removing mites.

The dust box 1 includes a filter 2, a box body 11, and a shield cover 12. Wherein the box 11 may be substantially cylindrical with an inner cavity 13, and a first opening 111 for cooperating with the filter 2 is provided on a side wall of the box 11. The cover 12 is attached to the case 11 on the peripheral side of the first opening 111, and the cover 12 has a first state of closing the first opening 111 and a second state of opening the first opening 111 when the filter 2 is inserted into the internal cavity 13.

As shown in fig. 2, that is, in a state where the first opening 111 is closed by the blocking cover 12. In this embodiment, the first opening 111 may be a circular opening, and in other embodiments, the first opening 111 may have other shapes as long as it can match the outer contour of the filter 2.

Fig. 3 is a sectional view of the dust box and the cover in a first state, as shown in fig. 3, when the filter 2 needs to be cleaned, the filter 2 can be detached from the first opening 111 for cleaning. When the filter 2 is removed, the first opening 111 is closed by the cover 12 under the influence of gravity. If the user forgets to insert the filter 2 and performs dust suction, the flap 12 is sucked to the first opening 111 by the generated wind pressure when the motor of the cleaner is started. Therefore, the sucked garbage or dust can not enter the motor, and the motor is prevented from being damaged.

Fig. 4 is a sectional view of the dust box and the cover in a second state, as shown in fig. 4, if the user does not forget to install the filter 2, the filter 2 will push the cover 12 open during the installation process, the air inlet 114 is communicated with the first opening 111, and the air enters the air duct for dust removal.

Fig. 5 is a schematic structural diagram of a box body of a dust collection box according to an embodiment of the present application, and fig. 6 is an enlarged view of a portion a in fig. 5. In a specific embodiment, as shown in fig. 5 and 6, the case 11 includes a sealing boss 112 disposed along the first opening 111, the sealing boss 112 protrudes toward the inner cavity 13 of the case 11, and the sealing boss 112 can be sealingly engaged with the cover 12 to close the first opening 111.

Since the inner wall of the box body 11 may not be flat or have poor flatness, the sealing boss 112 is disposed to cooperate with the blocking cover 12 to achieve sealing, so as to further prevent dust or garbage from entering the motor.

Fig. 7 is a schematic structural diagram of a blocking cover of a dust collection box according to an embodiment of the present disclosure, and as shown in fig. 6 and 7, in a specific embodiment, the box body 11 includes opposite mounting ears 113, the mounting ears 113 are provided with mounting holes 113a, the blocking cover 12 is provided with mounting shafts 121, and the mounting shafts 121 are rotatably connected to the mounting holes 113 a.

The mounting shaft 121 is rotatably engaged with the mounting hole 113a, so that the cover 12 can rotate to a position for closing the first opening 111 under the action of gravity. The flap 12 can be rotated to a position to open the first opening 111 when it receives the urging force of the filter 2.

In one particular embodiment, as shown in fig. 7, the shield cover 12 is provided with a coupling plate 122, and the mounting shafts 121 are provided on both sides of the coupling plate 122.

In this embodiment, the connecting plate 122 is disposed to make the mounting shaft 121 spatially match with the mounting hole 113a of the mounting lug 113, so as to achieve the angle at which the flap 12 needs to be opened.

As a possible implementation, the mounting shaft 121 is integrally formed with the connecting plate 122. It is understood that the mounting shaft 121 and the connecting plate 122 may be connected by other detachable connection methods, and are not limited in particular.

As a possible implementation, the mounting ears 113 are integrally formed with the seal boss 112. It is understood that the mounting ears 113 and the sealing bosses 112 may be connected by other detachable connection means, and are not limited in particular.

In a specific implementation, as shown in fig. 3 and 4, the box body 11 is provided with an air inlet 114, as shown in fig. 4, the air inlet 114 is used for communicating with the first opening 111 when the cover 12 opens the first opening 111. At this time, the sucked garbage and dust are introduced into the filter 2, not into the motor.

Further, the dust box 1 further includes a baffle 15, and the baffle 15 is blocked at the air inlet 114. By providing the baffle 15 to block the air inlet 114, dust on the filter 2 inside the case 11 can be prevented from falling out.

As shown in fig. 1 and 2, the dust box 1 further includes an upper cover 14, and the upper cover 14 is connected to the box body 11 to close the inner cavity 13. When the dust collector works, the inner cavity 13 can be sealed by the upper cover 14, so that the leakage of garbage and dust is avoided.

Further, the upper lid 14 has an inclined inner surface, and when the cover 12 is in the second state, a cavity 16 is formed between the cover 12, the filter 2, and the case 11. By arranging the upper cover 14 to have an inclined inner surface, when the blocking cover 12 is opened, a cavity 16 with a cross section approximately in a triangular shape can be formed between the blocking cover 12 and the filter 2 and the box body 11 under the limiting action of the inclined surface of the upper cover 14, so that the air flow in the box body 11 can form rotary air flow, and the dust collection effect is improved.

The embodiment of the application also provides a dust collector which comprises a filter 2 and a dust collection box. Wherein, the dust absorption box is the dust absorption box 1 that this application arbitrary embodiment provided, and filter 2 is installed in the first opening 111 of dust absorption box 1.

When the dust collector works, sucked dust or garbage enters the filter 2 through the inner cavity 13 of the dust collection box 1, and the filter 2 can filter the garbage or the dust.

Since the dust box 1 includes the blocking cover 12, even in the case where the user forgets to install the filter 2, the dust and dirt do not enter the motor through the dust box 1, causing damage to the motor.

Fig. 8 is a schematic structural view of a filter of a vacuum cleaner according to an embodiment of the present disclosure, and as shown in fig. 8, in a specific embodiment, the filter 2 includes a body 21 and a position-limiting portion 22 connected to the body 21. The body 21 is engaged with the first opening 111, and the limiting portion 22 is engaged with the outer wall of the box 11 to limit the body 21 at the first opening 111.

Referring to fig. 4 and 8, when the filter 2 is installed in cooperation with the case 11, the stopper 22 is provided to prevent the filter 2 from coming off, thereby improving the connection reliability of the filter 2.
