Embodiments of the present utility model are described below with reference to fig. 1 to 6.

According to an aspect of the embodiment of the present utility model, there is provided a dust collecting box including a box body 1, an inclined structure 2, a dust discharge passage 13 and a dust discharge cover structure 3, wherein the box body 1 has a dust collecting cavity 11, the inclined structure 2 is provided at a cavity wall of the dust collecting cavity 11, the inclined structure 2 is provided with a dust discharge port 21, the dust discharge passage 13 is formed by the cooperation of the inclined structure 2 and an inner wall of the box body 1, the dust discharge passage 13 is communicated through the dust discharge port 21 and the dust collecting cavity 11, the dust discharge cover structure 3 has a dust collecting state and a dust discharge state, in the dust collecting state, the dust discharge cover structure 3 closes the dust discharge port 21, and in the dust discharge state, the dust discharge cover structure 3 opens the dust discharge port 21.

According to the dust collecting box of the embodiment, the inclined structure 2 is arranged on the cavity wall of the box body 1, the inclined structure 2 is matched with the inner wall of the box body 1 to form the dust discharging channel 13, the dust collecting cavity 11 is communicated with the dust discharging channel 13 through the dust discharging port 21 on the inclined structure 2, the dust discharging cover structure 3 seals the dust discharging port 21 in a dust collecting state so as to ensure the normal dust collecting function of the dust collecting cavity 11, the dust discharging port 21 is opened by the dust discharging cover structure 3 in the dust discharging state, the dust discharging channel 13 is in butt joint with the external base station dust collecting channel 10, so that garbage in the dust collecting cavity 11 can be discharged to the dust discharging channel 13 through the dust discharging channel 21 of the inclined structure 2, and the dust collecting channel used for butt joint of the dust collecting box and the base station dust collecting channel 10 is not required to be independently configured in the dust sweeper, so that the internal space of the dust sweeper is saved, and the small-size and lightweight design of the dust sweeper is facilitated.

In this embodiment, the box body 1 is a square box body, and a dust collecting cavity 11 for containing dust and other garbage and a dust discharging channel 13 for discharging dust are formed inside the box body, and the dust collecting cavity 11 and the dust discharging channel 13 are square and matched with the box body 1 in shape.

In order to facilitate dust and other garbage to enter the dust collection cavity 11, the box body 1 of the embodiment is provided with a dust inlet 121 communicated with the dust collection cavity 11, and the dust and other garbage is sucked into the dust collection cavity 11 through the dust inlet 121.

In terms of the arrangement shape, the shape of the dust inlet 121 may be circular, elliptical or geometric. In this embodiment, the dust inlet 121 is rectangular in shape.

It will be appreciated that the height of the bottom edge of the dust inlet 121 defines the dust collection depth of the dust collection chamber 11 (i.e., the capacity of the dust collection chamber 11), and dust and other debris easily leaks out of the dust inlet 121 when the dust collection height in the dust collection chamber 11 exceeds the bottom edge position of the dust inlet 121. Therefore, in this embodiment, an inclined sidewall is disposed on the box body 1, and the dust inlet 121 is disposed on the inclined sidewall, so that the bottom edge position of the dust inlet 121 can be properly increased while the opening area of the dust inlet 121 is ensured, the clamping stagnation of the garbage at the dust inlet 121 is reduced, and the capacity of the dust collecting chamber 11 is increased.

Specifically, the inclined structure 2 may be a partition plate obliquely arranged in the box body 1, and the dust exhaust channel 13 is formed by matching between the inner wall of the box body 1 and the partition plate, and the dust exhaust port 21 is arranged on the partition plate.

Of course, in other embodiments, the inclined structure 2 may be an inclined wall integrally formed with the cavity wall of the box body 1, and the dust discharge channel 13 is formed by cooperation between the inner wall of the box body 1 and the inclined wall, and the dust discharge opening 21 is formed on the inclined wall.

Further, as shown in fig. 2, the inclined structure 2 is disposed at an acute angle α between the plane and the horizontal plane. Through this setting, make the inclined structure 2 place the plane and be the acute angle between the horizontal plane, the inclined structure 2 is the acute angle slope setting for the horizontal plane promptly, can reduce the pile up condition of rubbish on inclined structure 2, reduces the condition that dust exhaust mouth 21 blocked rubbish.

In the specific setting angle, in this embodiment, the setting range of α is 45 ° to 65 °, so that the inclination angle of the inclined structure 2 is in a suitable range, ensuring the volume of the dust discharge channel 13, and also making the garbage less prone to be accumulated on the inclined structure 2.

The value of α may be 45 °, 60 ° or 65 °, or the like, and the embodiment is not particularly limited.

Specifically, the inclined structure 2 and the inner wall of the box body 1 are matched to form a longitudinal dust discharging channel 13, and an outlet 131 of the dust discharging channel 13 is positioned at the bottom of the box body 1.

This sets up, and fore-and-aft dust removal passageway 13 and export 131 are located the bottom of box body 1, compares the dust collection wind channel that current horizontal set up, both makes things convenient for dust removal passageway 13 and base station dust collection wind channel 10 direct butt joint, makes things convenient for rubbish to discharge from the interior fore-and-aft of dust removal passageway 13, reduces the condition of card rubbish again, and rubbish drops out in the fore-and-aft dust removal passageway 13 because of the effect of gravity more easily promptly, promotes dust removal efficiency.

Specifically, the outlet 131 of the dust discharging channel 13 is arranged on the bottom surface of the box body 1, the bottom of the inclined structure 2 is arranged along the edge of the outlet 131 and is fixedly connected with the bottom surface of the box body 1, one surface of the inclined structure 2, which is away from the outlet 131, faces the inside of the dust collecting cavity 11, and one surface of the inclined structure 2, which is towards the outlet, is matched with the inner wall of the box body 1 to form the dust discharging channel 13.

The dust discharge passage 13 is a tapered passage with a small upper part and a large lower part in the overall shape, and the cross-sectional area at the outlet 131 of the dust discharge passage 13 is the largest in size.

The dust discharge port 21 facilitates the discharge of the garbage accumulated in the dust collection chamber 11 to the dust discharge channel 13, thereby realizing the repeated dust collection of the dust collection chamber 11. The shape of the dust discharge opening 21 may be circular, oval or geometric. In the present embodiment, the dust discharge port 21 is provided in a rectangular shape.

The projection of the outlet 131 of the dust discharging channel 13 on the bottom surface of the box body 1 and the projection of the dust discharging opening 21 in the longitudinal direction are overlapped, and the area of the outlet 131 is larger than the projection area of the dust discharging opening 21, so that dust discharging is facilitated. The longitudinal direction of the present embodiment is identical to the height direction of the dust box.

In this embodiment, the height of the top edge of the dust discharge opening 21 is greater than or equal to the height of the bottom edge of the dust inlet 121. According to the arrangement, the height of the top edge of the dust discharge port 21 is not lower than the height of the bottom edge of the dust inlet 121, so that the dust discharge port 21 is prevented from being completely covered and blocked by the garbage before dust discharge of the dust collecting box works, and the problem that the dust discharge port 21 is easily blocked by the garbage at the moment of starting dust discharge is solved.

In this embodiment, the top edge of the dust discharge port 21 is slightly higher than the bottom edge of the dust inlet 121, so as to ensure that a part of the dust discharge port 21 is not blocked by the dust, and the dust discharge port 21 is kept in communication with the dust collection chamber 11.

It should be noted that, too low a bottom edge of the dust inlet 121 may result in too small a volume of the dust collecting chamber 11, and too high a bottom edge of the dust inlet 121 may result in low sweeping and dust removing efficiency, so the height of the top edge of the dust outlet 21 may not be adjusted at will, and generally the height of the top edge of the dust outlet 21 is not lower than the height of the bottom edge of the dust inlet 121 by adjusting the height of the top edge of the dust outlet 21.

Further, the area of the dust discharge opening 21 is smaller than or equal to the cross-sectional area of the outlet 131 of the dust discharge passage 13. By arranging the area of the dust discharge port 21 not larger than the cross-sectional area of the outlet 131 of the dust discharge channel 13, the discharged garbage of the dust discharge port 21 can be discharged smoothly through the outlet 131 of the dust discharge channel 13, the situation that the garbage is blocked and accumulated in the outlet 131 of the dust discharge channel 13 due to excessive garbage discharged by the dust discharge port 21 is avoided, and the dust discharge smoothness is improved.

Here, if the area of the dust discharge port 21 is larger than the cross-sectional area of the outlet 131 of the dust discharge passage 13, it is explained that the amount of the dust discharged from the dust discharge port 21 is larger than the discharge amount from the outlet 131 of the dust discharge passage 13, and the remaining dust is easily accumulated in the dust discharge passage 13, resulting in a gradual increase in the density of the dust in the dust discharge passage 13, formation of accumulation, and easy sticking in the outlet 131 of the dust discharge passage 13, so that the present application solves the technical problem by reasonably setting the area of the dust discharge port 21 to be not larger than the cross-sectional area of the outlet 131 of the dust discharge passage 13.

The test analysis shows that the relation between the working efficiency of the fan of the dust collecting box and the cross section area of the dust discharging channel 13 is parabolic, and the cross section area of the dust discharging channel 13 is 860mm ²～960mm² through data analysis, so that the best performance of the dust collecting system can be ensured.

In some embodiments, the dust discharge channel 13 may be provided as a circular channel with a pore size of 33 mm-35 mm. The aperture of the dust discharging channel 13 is set in a reasonable range, so that the dust discharging efficiency of the dust discharging channel 13 is ensured, and the situation that the dust discharging channel 13 is too large to occupy too much space in the box body 1 is avoided.

By way of example, the cross-sectional area of the dust discharge passage 13 may be set to 860mm ²、900mm², 960mm ², or the like, and the aperture of the dust discharge passage 13 may be set to 33mm, 34mm, 35mm, or the like, without being particularly limited in this embodiment.

In terms of a specific connection mode, the dust exhaust cover structure 3 can be rotatably connected with the inclined structure 2. The dust discharge opening 21 is closed or opened by the rotation of the dust discharge blocking cover structure 3 relative to the inclined structure 2, so that the switching between the dust collection state and the dust discharge state is realized, and the operation is very convenient.

Further, the dust exhaust cover structure 3 of the present embodiment is located at one side of the dust exhaust channel 13, and can rotate to a dust exhaust state relative to the inclined structure 2 by the acting force of the dust exhaust air flow in the dust exhaust channel 13.

When the dust removing device is used for dust removing operation, the dust removing cover structure 3 can rotate to a dust removing state relative to the inclined structure 2 through the acting force of dust removing air flow in the dust removing channel 13, so that the dust removing opening 21 is opened for dust removing operation, the dust removing cover structure 3 is not required to be driven to rotate relative to the inclined structure 2 by an additional power part, and the purposes of simplifying the structure and saving the setting cost and space are achieved.

In terms of specific structural arrangement, the dust-exhausting cover structure 3 of the present embodiment includes a dust-collecting cover plate 31, the upper edge of the dust-collecting cover plate 31 is rotatably connected to the inclined structure 2 through a rotating shaft 32, and the dust-collecting cover plate 31 is used for closing or opening the dust-exhausting port 21.

The dust collecting cover plate 31 rotates around the rotating shaft 32 towards the inclined structure 2 to seal the dust discharge opening 21, so that dust collecting operation of the dust collecting box is realized, and the dust collecting cover plate 31 rotates around the rotating shaft 32 away from the inclined structure 2 to open the dust discharge opening 21, so that dust discharging operation of the dust collecting box is realized.

In this embodiment, the upper edge of the dust collecting cover plate 31 is rotatably connected with the partition plate through the rotating shaft 32, and the size of the dust collecting cover plate 31 is larger than the size of the dust discharge opening 21, so that the dust collecting cover plate 31 can completely close the dust discharge opening 21 in a dust collecting state, and the tightness of the dust discharge opening 21 is ensured.

In addition, the dust-discharging cover structure 3 further comprises an elastic reset piece 33, the elastic reset piece 33 is connected with the dust collecting cover plate 31 and the inclined structure 2, and the elastic reset piece 33 is configured to drive the dust collecting cover plate 31 to rotate to a dust collecting state relative to the inclined structure 2 through self elastic force.

Above-mentioned setting, the in-process that dust collecting cover plate 31 rotated to the dust state with the help of the effort of the interior dust exhaust air current of dust exhaust passageway 13 relative to inclined structure 2, the elasticity reposition of redundant personnel 33 that sets up is compressed or tensile by elasticity, after the effort of dust exhaust air current disappears, the dust collecting cover plate 31 rotates to the dust collection state with relative inclined structure 2 under the resilience of elasticity reposition of redundant personnel 33, make things convenient for dust collection chamber 11 to carry out dust collection operation, simultaneously elasticity reposition of redundant personnel 33 can also provide the pretightning force to dust collecting cover plate 31, make dust collecting cover plate 31 closely paste and locate inclined structure 2, and then ensure the leakproofness to dust exhaust mouth 21.

It will be understood that during normal dust collection operation of the dust collection chamber 11, the dust collection air flow in the dust collection chamber 11 will generate an adsorption force on the dust collection cover plate 31, so as to promote the dust collection cover plate 31 to be closely attached to the partition plate, and enhance the tightness of the dust collection cover plate 31 to the dust discharge port 21.

In this embodiment, the elastic restoring member 33 is a torsion spring, the torsion spring is disposed on the rotating shaft 32, and two ends of the torsion spring are respectively connected with the partition board and the dust collecting cover plate 31. Of course, in other embodiments, the elastic restoring member 33 may be provided as a spring or a shrapnel, which is not limited to the solution of this embodiment.

Because there is an unavoidable fit gap between the inclined structure 2 and the dust collecting cover plate 31, on the one hand, the dust in the dust collecting chamber 11 is likely to leak to the dust discharging passage 13 through the fit gap, and on the other hand, the dust collecting effect of the dust collecting chamber 11 is also affected by the fit gap, and on the other hand, the dust discharging cover plate structure 3 of the present embodiment further includes a sealing member 34, the sealing member 34 being disposed between the dust collecting cover plate 31 and the inclined structure 2, for sealing the gap between the dust collecting cover plate 31 and the inclined structure 2 in the dust collecting state.

The sealing piece 34 is arranged between the dust collecting cover plate 31 and the inclined structure 2, so that when the dust collecting cover plate 31 is in a dust collecting state, the sealing piece 34 is used for sealing a gap between the dust collecting cover plate 31 and the inclined structure 2, thereby avoiding the leakage of garbage from the gap between the dust collecting cover plate 31 and the inclined structure, and ensuring the dust collecting effect in the dust collecting cavity 11.

It should be noted that, when a larger fit gap exists between the inclined structure 2 and the dust collecting cover plate 31, a part of the air suction of the fan of the dust collecting box is sucked from the dust outlet 21 through the fit gap between the inclined structure 2 and the dust collecting cover plate 31, so that the air suction of the fan can only partially come from the dust inlet 121, thereby reducing the dust collecting effect of the dust collecting box, resulting in overlarge power loss of the fan, and the sealing element 34 can seal the fit gap between the inclined structure 2 and the dust collecting cover plate 31, so that the air suction of the fan of the dust collecting box is ensured to come from the dust inlet 121, and the dust collecting effect of the dust collecting box is ensured.

Preferably, the sealing member 34 is arranged in a ring shape along the edge of the dust discharge opening 21. The sealing element 34 is arranged in a ring shape along the edge of the dust discharge opening 21, so that the edge of the dust discharge opening 21 can be completely sealed by the sealing element 34, and the sealing effect is ensured.

Specifically, since the dust discharge port 21 of the present embodiment is rectangular, the seal 34 is provided as a rectangular seal along the edge of the dust discharge port 21.
