At present, in a cleaning mode of a cleaning device, impurities such as dust and debris on a floor are sucked into a dust box of the cleaning device along with air, due to the effect of a filter (also called as HEPA) on the dust box, the air flows out from a vent of the filter, when the impurities are gathered in the dust box, a lot of dust is remained on the filter close to the inner side of the dust box, and in the prior art, the filter on the dust box needs to be cleaned regularly by manpower, so that the filter is prevented from being blocked due to long-time use, and the normal operation of the cleaning device is prevented from being influenced.
To this end, the present application provides the following embodiments to solve or improve the problems of the prior art. In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
The first embodiment is as follows:
fig. 1 is a schematic structural diagram of a cleaning device according to an embodiment of the present invention. FIG. 2 illustrates a schematic structural view of a dirt box assembly provided by one embodiment of the present invention. As shown in fig. 1, the cleaning device includes a body 2 and a dust box assembly 4, and the dust box assembly 4 is detachably coupled to the body 2. For example, the body 2 may be formed with an accommodating space for accommodating the dust box assembly 4, and the dust box assembly 4 may be placed in the accommodating space and detachably connect the dust box assembly 4 with the body 2 by a detachable connector, such as a snap, a bolt, or the like. In the concrete implementation, the machine body 2 is provided with a suction port 3, and the suction port 3 is communicated with the dust box assembly 4.
As shown in fig. 2, the dust box assembly 4 includes a box body 6, the box body 6 is provided with a dust inlet 5, a dust outlet 7 and a ventilation opening 8, and the ventilation opening 8 is provided with a filter 9. In the concrete implementation, the dust inlet 5 is communicated with the suction port 3 on the machine body 2.
The present invention is different from the prior art in that the dust box assembly 4 further comprises a controllable dust blocking sheet 10 and a driving module 11 for controlling the dust blocking sheet 10, the dust blocking sheet 10 is movably arranged at the dust inlet 5, and in the first operation mode of the machine body 2, the driving module 11 controls the dust blocking sheet 10 to close the dust inlet 5, so that the residual dust on the filter 9 is discharged out of the dust outlet 7 along with the airflow by the air entering from the air vent 8 under the action of the suction airflow. It is noted that the suction force forming the suction air flow is generated by a vacuum source on the cleaning device or the base.
In practical implementation, the machine body 2 may include at least two operation modes, i.e. a first operation mode and a second operation mode, and the following describes a specific operation principle of the dust box assembly 4:
fig. 3 shows the state of the dust box assembly 4 in the second operation mode of the machine body 2, as shown in fig. 3, when the machine body 2 is in the second operation mode, the driving module 11 controls the dust blocking sheet 10 to open the dust inlet 5, so as to suck the interior of the dust box assembly 4 into vacuum, when the vacuum degree inside the dust box assembly 4 reaches a certain degree, because the dust outlet 7 is in the closed state in the second operation mode, the air outside the cleaning device enters the dust box assembly 4 through the dust inlet 5, so that a suction airflow is formed inside the dust box assembly 4, because the dust inlet 5 is communicated with the suction port 3 on the machine body 2, the impurities on the surface of the machine body 2 are sucked into the dust box assembly 4 along with the air under the action of the suction airflow, and the sucked air is filtered by the filter 9 and then flows out of the ventilation port 8, so that the impurities are gathered inside the dust box assembly 4, dust also remains on the filter 9 near the inside of the dust box assembly 4 and as the usage time accumulates, more and more dust remains on the filter 9, which can cause the filter to clog if not cleaned in time, thereby affecting the normal operation of the cleaning device.
Based on this, in order to achieve the purpose of automatically cleaning the dust on the filter 9, the present invention cleans the filter 9 at the same time of collecting dust in the first operation mode, fig. 4 shows the state of the dust box assembly 4 of the machine body 2 in the first operation mode, as shown in fig. 4, in the first operation mode of the machine body 2, the driving module 11 controls the dust blocking sheet 10 to close the dust inlet 5, so as to suck the inside of the dust box assembly 4 to be vacuum, when the vacuum degree inside the dust box assembly 4 reaches a certain degree, because the dust inlet 5 is closed by the dust blocking sheet 10, the air outside the cleaning device can only enter the dust box assembly 4 through the filter 9 at the vent 8, so as to form a suction air flow inside the dust box assembly 4, because in the first operation mode, the dust outlet 7 is in an open state, therefore, under the action of the suction air flow, the dust, debris and other impurities inside the dust box assembly 4 are discharged from the dust outlet 7 along with the air flow, meanwhile, because there is a large negative pressure inside and outside the filter 9, the air will carry away the dust remained on the filter 9 during the process of entering the dust box assembly 4 through the filter 9, and then will be discharged from the dust outlet 7 along with the air flow.
In this embodiment, for the sweeping robot, the second operation mode refers to a sweeping mode of the cleaning device, and the first operation mode refers to a dust collecting mode of the cleaning device, so that the filter 9 is automatically cleaned while collecting dust, and the filter 9 is always kept in a clean state because each time the cleaning device collects dust, the dust remaining on the filter 9 is cleaned.
It will be appreciated by those skilled in the art that the first mode of operation described above may of course be other than a dust collection mode of the cleaning apparatus. That is, the above-described filter cleaning process can be implemented either in combination in the dust collection mode or in a single operation mode other than the cleaning mode and the dust collection mode. It should be further noted that the shape of the dust inlet 5 may be rectangular, circular, triangular or other shapes, which are not particularly limited in this embodiment, and the shape of the dust blocking sheet 10 is also not limited as long as the dust blocking sheet 10 can completely cover the dust inlet 5, so as to completely close the dust inlet 5.
In an optional specific implementation manner, the dust blocking sheet 10 may be made of a thin plastic part, which has a light weight and a simple processing process, and may be formed in batch by injection molding.
In the present embodiment, the dust blocking sheet 10 is movably disposed at the dust inlet 5, which means that the dust blocking sheet 10 can move in a certain manner, for example, flip, slide, etc., to change the position of the dust blocking sheet 10 relative to the dust inlet 5, so as to open or close the dust inlet 5.
In a preferred embodiment, the dust barrier sheet 10 is reversibly arranged at the dust inlet 5. Specifically, one side edge of the dust-blocking sheet 10 is hinged to the box body 6.
Taking the shape of the dust inlet 5 as a rectangle as an example, the dust inlet 5 may include an upper edge, a lower edge, a left edge, and a right edge, and one side edge of the dust blocking sheet 10 is hinged to one of the upper edge, the lower edge, the left edge, and the right edge of the dust inlet 5 on the box body 6.
It should be noted that the present invention is not particularly limited to the implementation manner of the open state and the closed state of the dust exhaust port 7, and can be implemented by using the related art. In addition, in the dust collection mode, the dust discharge port 7 is butted with a butt joint port on the base, and the butt joint port of the base can be coated with soft rubber, so that good air tightness is ensured, and dust overflow in the dust collection process is avoided.
Based on the above description, can know, through set up controllable fender dirt piece in the dust inlet department of dirt box subassembly, and set up the drive module who keeps off the dirt piece on the dirt box subassembly, thereby be in under the collection dirt mode (being first mode) when cleaning device, keep off the dirt piece closure through drive module control, with the totally enclosed dust inlet, thereby, the dust exhaust mouth on the dirt box subassembly is opened and is discharged the debris in the dirt box subassembly under the effect of suction air current, gaseous in-process that gets into in the dirt box subassembly through the vent simultaneously, can discharge the dust of gathering on the filter along with the air current from the dust exhaust mouth, thereby reach the purpose of automatic clearance filter, avoid the artifical dust on the regular clearance filter.
In some embodiments, the driving module 11 may include a controller and a driving mechanism, the controller needs to be electrically connected with the controller of the machine body 2 on the cleaning device to detect the working mode of the machine body 2, and at the same time, the controller needs to be electrically connected with the driving mechanism to control the driving mechanism to output the driving force.
In specific implementation, when the controller detects that the machine body 2 is in the first working mode, the controller controls the driving mechanism to output corresponding driving force to drive the dust blocking sheet 10 to close the dust inlet 5, and when the controller detects that the machine body 2 is in the second working mode, the controller controls the driving mechanism to output corresponding driving force to drive the dust blocking sheet 10 to open the dust inlet 5.
In the present embodiment, since the dust blocking sheet 10 is electrically controlled by the driving mechanism to open or close the dust inlet 5, the opening or closing of the dust blocking sheet 10 is not affected by external force, and the dust inlet 5 can be effectively and reliably opened or closed.
In an alternative embodiment, the driving mechanism included in the driving module 11 may include a motor and a transmission assembly.
The motor is used for outputting driving force, and the transmission assembly is used for driving the dust blocking piece 10 to move under the action of the driving force.
In another alternative embodiment, the driving mechanism included in the driving module 11 may also be an electromagnet and a transmission assembly.
The electromagnet is used for outputting driving force, and the transmission assembly is used for driving the dust blocking sheet 10 to move under the action of the driving force.
Additionally, the transmission mode of the transmission assembly may include at least one of the following: gear drive, chain drive, belt drive, link drive.
In an alternative embodiment, when the transmission assembly in the driving mechanism is a belt transmission, the driving mechanism may include a first rotating wheel, a second rotating wheel, and a belt pulley for connecting the first rotating wheel and the second rotating wheel, the first rotating wheel is fixedly connected with the motor/electromagnet, the second rotating wheel is fixedly connected with the dust-blocking sheet 10, and preferably, the rotation axis of the second rotating wheel coincides with the rotation axis of the dust-blocking sheet 10.
In another alternative specific example, when the transmission assembly in the driving mechanism is a gear transmission, the driving mechanism may include a first gear, a second gear and a third gear, the first gear is fixedly connected with the motor/electromagnet, the second gear is disposed between the first gear and the third gear, and the second gear is meshed with the first gear and the third gear.
Preferably, the axis of rotation of the third gear coincides with the axis of rotation of the dust deflector 10.
It is understood that, for the specific structural design of the transmission assembly, the two examples are only specific examples of different transmission manners, and actually, there may be many other transmission manners, which may be specifically designed and selected according to actual situations, as long as the transmission assembly can drive the dust blocking sheet 10 to open or close the dust inlet 5 under the driving of the motor/electromagnet, and details of this embodiment are not described herein again.
In an alternative embodiment, in order to improve the sealing effect of the dust flap 10 closing the dust inlet 5, the suction of gas from the dust inlet 5 in the first operation mode is prevented, and the automatic cleaning capability of the filter 9 is reduced. When the dust-blocking piece 10 moves to the preset angle range, the box body 6 and the dust-blocking piece 10 can be magnetically attracted.
In specific implementation, magnets are arranged on the box body 6 and the dust blocking piece 10, and the polarities of the magnets on the box body 6 and the magnets on the dust blocking piece 10 are opposite; alternatively, a magnet is provided on one of the box 6 and the dust-blocking sheet 10, and a metal capable of being attracted by the magnet is provided on the other of the box 6 and the dust-blocking sheet 10.
Wherein the metal capable of being attracted by the magnet may include: iron, nickel, cobalt, and also certain alloys thereof.
Therefore, by adopting the magnetic attraction mode, when the dust blocking sheet 10 rotates to the distance which can sense the magnetism of the box body 6 on the box body 6, the dust blocking sheet 10 is attached to the box body 6, so that the stability and the tightness of the dust blocking sheet 10 for closing the dust inlet 5 are improved, gas is prevented from being sucked from the dust inlet 5 in the first working mode, and the automatic cleaning capability of the filter 9 is weakened.
Moreover, according to the technical solution provided in this embodiment, the dust inlet 5 is opened by the dust blocking sheet 10 through the driving mechanism, so that even if the dust blocking sheet is magnetically attracted to the box body 6 by 10 times, the controller in the driving module only needs to control the driving mechanism to output a corresponding driving force, so that the dust blocking sheet 10 overcomes the magnetic attraction force along the direction of opening the dust inlet 5 to open the dust inlet 5.
Preferably, in the present embodiment, the dust-blocking sheet 10 is rotated in a direction away from the dust inlet 5 and toward the inside of the case 6 to open the dust inlet 5. That is to say, the opening direction of the dust blocking sheet 10 for opening the dust inlet 5 is consistent with the wind direction of the fan, and structurally, the dust blocking sheet 10 can be arranged on the inner side wall of the box body 6, specifically, since the wind direction of the fan blows from the outer side of the dust inlet 5 to the inner side of the box body 6, the opening direction of the dust blocking sheet 10 is consistent with the wind direction of the fan, and the dust blocking sheet 10 can be further maintained at the opening position by the wind force of the fan to a certain extent.

Taking the cleaning device as a sweeping robot as an example, the first working mode is a dust collecting mode, and the second working mode is a sweeping mode. In the cleaning mode, a rechargeable battery in the robot body of the sweeping robot is used as an energy source. Through the energy supply of the rechargeable battery, the sweeping robot body moves on the ground to be treated, and meanwhile, dust particles on the ground to be treated are sucked into the box body of the dust box component through the suction port. During cleaning, sensors arranged on the sweeping robot can detect the amount of dust and debris accumulated in the box body of the dust box assembly, and in operation, whether the amount of dust and debris accumulated in the box body exceeds a standard value or not is determined according to the detected data.
When the quantity of the dust and the fragments accumulated in the box body of the dust box component is determined to exceed the standard value in operation, the sweeping robot stops the automatic cleaning operation and moves towards the base until the sweeping robot moves to the base, the base is butted, and the sweeping robot is switched to a dust collection mode.
In the dust collection mode, a dust discharge port at the bottom of the sweeping robot is connected with a suction channel of a dust collection chamber in the base. When the sweeping robot returns to the base for charging, the charging battery of the machine body is successfully butted with the charging electrode of the charging seat. After the suction channel of the base is communicated with the dust exhaust port at the bottom of the sweeping robot, the sweeping robot enters a charging and dust collecting mode, and a vacuum source in the base starts to work. Under the suction of a vacuum source, air enters the box body of the dust box component from the ventilation opening of the dust box component, and air flow drives dust particles in the box body to flow out of the box body through the air channel and enter the suction channel of the base together through the box body, so that the dust particles finally enter the dust collecting chamber of the base.
