When the dirt tray assembly is removed from the cleaning device, the handle 30 is lifted, i.e., the handle 30 is lifted to the second predetermined position. Thus, it can be distinguished by the handle 30 being in either the first preset position or the second preset position that the dust box assembly is in the installed or removed from the cleaning apparatus. In this embodiment, the preset included angle is preferably 90 °.

The dust guard transmission mechanism 40 is used for driving the dust guard 20 to move. The dust blocking member driving mechanism 40 can drive the dust blocking member 20 to move according to the position of the handle 30, so that when the handle 30 is located at the second preset position, the dust blocking member 20 is in a state of closing the dust inlet 11.

The dust box assembly provided by the embodiment of the invention comprises a box body, a handle and a dust blocking part, wherein a dust blocking part driving mechanism drives the dust blocking part to move according to the position of the handle, and when the handle is positioned at a second preset position, the dust blocking part is in a state of closing a dust inlet. According to the technical scheme, the dust blocking part is driven by the dust blocking part driving mechanism according to the position of the handle to close the dust inlet, the dust blocking part is closed to the dust inlet through the dust blocking part driving mechanism, the dust blocking part is not influenced by the dead weight of the dust blocking part, and the dust inlet can be effectively and reliably closed. The following provides a specific implementation form of the dust blocking member transmission mechanism 40, specifically, the dust blocking member transmission mechanism 40 may be connected to the handle 30 and the dust blocking member 20 respectively, and the dust blocking member driving mechanism 40 is configured to drive the dust blocking member 20 to open or close the dust inlet along with the change of the position of the handle 30. Wherein, when the handle 30 is located at the first predetermined position, the dust blocking member 20 opens the dust inlet 11, and when the handle 30 is located at the second predetermined position, the dust blocking member 20 closes the dust inlet 11.

The transmission mode of the dust barrier driving mechanism in the embodiment may include at least one of the following: gear drive, chain drive, belt drive, link drive.

For example, as shown in fig. 4, the dust guard driving mechanism 40 of the present embodiment includes a first rotating wheel 41, a second rotating wheel 42, and a pulley 43 for connecting the first rotating wheel 41 and the second rotating wheel 42, the first rotating wheel 41 is fixedly connected to the handle 30, and preferably, the rotation axis of the first rotating wheel 41 coincides with the rotation axis of the handle 30, and the second rotating wheel 42 is fixedly connected to the dust guard 20, and preferably, the rotation axis of the second rotating wheel 42 coincides with the rotation axis of the dust guard 20.

Taking the view shown in fig. 4 as an example, in the state that the handle 30 is at the second preset position in fig. 4, when the handle 30 rotates counterclockwise to the first preset position, the handle 30 is put down, because the handle 30 is fixedly connected with the first rotating wheel 41, the first rotating wheel 41 rotates counterclockwise, the belt pulley 43 drives the second rotating wheel 42 to rotate counterclockwise, and because the second rotating wheel 42 is fixedly connected with the dust blocking member 20, the dust blocking member 20 rotates counterclockwise to open the dust inlet 11. When the handle 30 rotates clockwise from the first preset position to the second preset position, the handle 30 is lifted, the first rotating wheel 41 rotates clockwise due to the fixed connection between the handle 30 and the first rotating wheel 41, the belt pulley 43 drives the second rotating wheel 42 to rotate clockwise, and the dust blocking member 20 rotates clockwise to close the dust inlet 11 due to the fixed connection between the second rotating wheel 42 and the dust blocking member 20.

Alternatively, the dust blocking member driving mechanism 40 may also be a gear mechanism, and fig. 5 is a schematic structural diagram of a transmission mechanism according to an embodiment of the present invention; as shown in fig. 2-5, the dust guard driving mechanism 40 may include a first gear 41a, a second gear 42a and a third gear 43a, the first gear 41a is fixedly connected to the handle 30, the second gear 42a is disposed between the first gear 41a and the third gear 43a, and the second gear 42a is engaged with the first gear 41a and the third gear 43 a. Preferably, the rotation axis of the first gear 41a coincides with the rotation axis of the handle 30, and preferably, the rotation axis of the third gear 43a coincides with the rotation axis of the dust guard 20.

The handle 30 rotates counterclockwise, and in the process of rotating from the second preset position to the first preset position, the handle 30 is put down, because the handle 30 is fixedly connected with the first gear 41a, the handle 30 drives the first gear 41a to rotate counterclockwise, the first gear 41a drives the second gear 42a to rotate clockwise, the second gear 42a rotates clockwise to drive the third gear 43a to rotate counterclockwise, the third gear 43a is fixedly connected with the dust blocking member 20, and the third gear 43a rotates counterclockwise to drive the dust blocking member 20 to rotate counterclockwise and open the dust inlet 11. When the handle 30 rotates clockwise from the first preset position to the second preset position, the handle 30 is lifted, the first gear 41a rotates clockwise due to the fixed connection of the handle 30 and the first gear 41a, the second gear 42a rotates counterclockwise, the second gear 42a drives the third gear 43a to rotate clockwise, and the dust blocking member 20 rotates clockwise to close the dust inlet 11 due to the fixed connection of the third gear 43a and the dust blocking member 20.

It will be appreciated that, in order to allow the dust barrier 20 to smoothly open or close the dust inlet 11, the above-described dust barrier driving mechanisms 40 are respectively provided at both ends of the handle 30.

Of course, as for the structural design of the dust blocking member driving mechanism 40, the belt transmission manner shown in fig. 4 and the gear transmission manner shown in fig. 5 are examples, and actually, there may be many other transmission manners, which may be specifically designed and selected according to actual situations, as long as it is achieved that the driving mechanism drives the dust blocking member 20 to open the dust inlet 11 in the process of putting down the handle 30, which is not described in detail in this embodiment.

Further, the dirt box subassembly that this embodiment provided, connect handle and dust blocking piece with drive mechanism respectively, the effort transmission of handle is for dust blocking piece through drive mechanism, the handle can be for the box body motion in order to have first default position and the default position of second, drive mechanism drives dust blocking piece and switches between the state of opening or closing into the ash mouth through the position change of handle, the technical scheme of this embodiment, it opens or closes into the ash mouth to drive dust blocking piece through drive mechanism with the position change of handle, dust blocking piece is to the switching of entering the ash mouth through drive mechanism realization, do not receive the influence of dust blocking piece dead weight, can open or close into the ash mouth effectively reliably.

And, when the handle is in first default position, the handle flushes or is less than the upper surface of box body with the upper surface of box body, when the handle is in second default position, the handle is located the top of box body and forms the second default position of predetermineeing the contained angle with the upper surface of box body, when the handle is located first default position, dust blocking member opens into the ash mouth, when the handle is in the second default position, dust blocking member closes into the ash mouth, can realize when the dirt box is installed to the machine, the handle is put down to first default position, the handle passes through drive mechanism and drives dust blocking member and open into the ash mouth, when the dirt box takes out, the handle is mentioned to second default position, the handle passes through drive mechanism and drives dust blocking member and closes into the ash mouth.

The dirt box subassembly of this embodiment, compare in the prior art and close the scheme of entering ash mouth through the dead weight, the handle rotates and drives under drive mechanism's effect and keep off dirt spare and force to close into the ash mouth when taking out the dirt box, the condition that the ash mouth can't be closed into to the jam of keeping off dirt spare, and, this scheme can realize that the dust mouth opens when the dirt box subassembly is packed into the machine, keep off dirt spare and move to entering the ash mouth and close when taking out the dirt box, can not have the foreign matter dust to drop from the dirt box and form secondary pollution or damage the machine when taking out the dirt box subassembly, user experience and product reliability have been improved. And the opening of the dust inlet is opened by the linkage of the handle, and the dust inlet does not need to be blown up by a fan, so that the wind resistance of the fan cannot be influenced, and the dust collection effect of the cleaning equipment is improved.

As shown in fig. 1, the box 10 may further be provided with a groove 13 for accommodating the handle 30, and the handle 30 is located in the groove 13 when the handle 30 is in the first preset position. The shape of the groove 13 can be matched with that of the handle 30, the arrangement of the groove 13 can effectively utilize space, and the whole volume is saved. And an avoiding groove A1 can be formed on the first surface A, and the arrangement of the avoiding groove A1 can facilitate the user to lift the handle 30 from the avoiding groove A1.

To improve the sealing effect of the dust-blocking member 20 closing the dust inlet 11, dust is prevented from falling from the dust inlet 11 during the removal of the dust box. When the dust-blocking member 20 is turned over within a predetermined angle range, the box body 10 and the dust-blocking member 20 can be magnetically attracted. Specifically, magnets are arranged on the box body 10 and the dust blocking part 20, and the polarities of the magnets on the box body 10 and the magnets on the dust blocking part 20 are opposite; alternatively, a magnet is provided on one of the case 10 and the dust-blocking member 20, and a metal capable of being attracted by the magnet is provided on the other of the case 10 and the dust-blocking member 20. Wherein the metal capable of being attracted by the magnet may include: iron, nickel, cobalt, and also certain alloys thereof. By adopting the magnetic attraction mode, when the dust blocking part 20 rotates to the distance which can feel the magnetism of the box body 10 on the box body 10, the dust blocking part 20 is attached to the box body 10, thereby improving the stability and the tightness of the dust blocking part 20 for closing the dust inlet 11, and when the dust box is taken out from the machine, the dust and the garbage in the dust collecting cavity 12 can not fall out.

Moreover, according to the technical solution provided in this embodiment, the dust blocking member 20 is opened by the transmission mechanism instead of by the wind of the fan, so that even if the dust blocking member 20 is magnetically attracted to the box 10, the wind resistance of the fan is not increased, and the user only needs to put down the handle 30 by a certain force, so that the dust blocking member 11 overcomes the magnetic attraction force along the direction of opening the dust inlet 11 to open the dust inlet 11.

Preferably, in this embodiment, the dust barrier 20 is rotated in a direction away from the dust inlet 11 and toward the dust collection chamber 12 of the case 10 to open the dust inlet 11. That is, the opening direction of the dust blocking member 20 to the dust inlet is consistent with the wind direction of the fan, and structurally, the dust blocking member 20 may be disposed on the inner sidewall of the box 10, and specifically, since the wind direction of the fan blows toward the dust collecting chamber 12 from the outside of the dust inlet 11, the opening direction of the dust blocking member 20 is consistent with the wind direction of the fan, so that the dust blocking member 20 can be further maintained at the opening position by the wind force of the fan to some extent.

The direction in which the handle 30 drives the dust-blocking member 20 to rotate through the transmission mechanism is related to the arrangement and position of the handle 30 and the arrangement and position of the dust-blocking member 20. Specifically, as shown in fig. 4, in the arrangement and position of the handle 30 and the dust blocking member 20, in the process of turning the handle 30 from the first preset position to the second preset position along the first rotation direction (clockwise direction), the dust blocking member 20 is turned from the state of opening the dust inlet 11 to the state of closing the dust inlet 11 along the first rotation direction (clockwise direction). In the process that the handle 30 is turned from the second preset position to the first preset position along the second rotating direction (anticlockwise), the dust blocking member 20 is turned from the state of closing the dust inlet 11 to the state of opening the dust inlet 11 along the second rotating direction (anticlockwise); wherein the first rotational direction is opposite to the second rotational direction. When the handle 30 and the dust-blocking member 20 are arranged as shown in the figure, the rotation direction of the handle 30 is the same as the rotation direction of the dust-blocking member 20 when the handle 30 drives the dust-blocking member 20 to rotate.

Optionally, in the process that the handle 30 is turned from the first preset position to the second preset position along the first rotation direction, the dust blocking member 20 is turned from the state of opening the dust inlet to the state of closing the dust inlet along the second rotation direction (counterclockwise direction); in the process that the handle 30 is turned from the second preset position to the first preset position along the second rotation direction, the dust blocking member is turned from the state of closing the dust inlet to the state of opening the dust inlet along the first rotation direction (clockwise direction); wherein the first rotational direction is opposite to the second rotational direction. Of course, in this embodiment, the first rotation direction may also be a counterclockwise direction, and correspondingly, the second rotation direction is a clockwise direction.

It can be understood that when the arrangement and position of the handle 30 and the dust blocking member 20 determine that the handle 30 drives the dust blocking member 20 to rotate, the rotation directions of the two are consistent, and the arrangement position and rotation directions of the two are consistent to determine the selection of the transmission mechanism, for example, if a gear is used as the transmission mechanism, when the rotation directions of the two are consistent, the number of the external gears used may be an odd number (for example, the three gears described in the above embodiment: the first gear 41a, the second gear 42a and the third gear 43a), and when the rotation directions of the two are opposite, the number of the external gears used may be an even number.

As another alternative, the dust-blocking member 20 can be slidably disposed at the dust inlet 11, and the dust-blocking member driving mechanism 40 drives the dust-blocking member 20 to slide parallel to the dust inlet 11 to open or close the dust inlet 11 as the position of the handle 30 changes. A sliding groove for sliding the dust blocking member 20 may be provided on an inner sidewall of the case 10. The dust blocking member 20 may be slidable in the vertical direction or the horizontal direction, as long as the dust inlet 11 can be opened or closed, and the embodiment is not limited thereto. Those skilled in the art can design the dust barrier driving mechanism 40 according to the moving direction of the dust barrier 20 to open or close the dust inlet 11.

Taking the dust-blocking member 20 disposed below the dust inlet 11 as an example, the dust-blocking member 20 is lifted to open the dust inlet 11, the dust-blocking member 20 is lowered to close the dust inlet 11, and a connecting rod (not shown) may be disposed between the handle 30 and the dust-blocking member 20. When the handle 30 is pulled up, the dust blocking member 20 is pulled up by the link to close the dust inlet 11, and when the handle 30 is put down, the dust blocking member 20 is pushed down by the link to open the dust inlet 11.

Of course, those skilled in the art can design any other reasonable dust blocking member driving mechanism 40 to realize the transmission between the handle 30 and the dust blocking member 20, and the description of this embodiment is not repeated herein.

In addition, the dust box assembly of the above embodiment may further include: the drive mechanism protects the housing 50.
