Dust box assembly, cleaning equipment and cleaning system

Technical Field

The application relates to the technical field of cleaning equipment, in particular to a dust box assembly, cleaning equipment and a cleaning system.

Background

Currently, cleaning devices such as sweeping robots are capable of taking up dust from a surface to be cleaned into a dust box for storage. When the cleaning equipment is in butt joint with the base station, the base station can absorb dust in the dust box to the base station through a dust outlet on the dust box for storage.

Because the setting of current dirt box subassembly is unreasonable, the dust in the dirt box easily appears remaining or revealing when the basic station collection dirt, leads to the dust collection effect of basic station not ideal, and user experience is not good.

There is therefore a need for an improvement to at least partially solve the above-mentioned problems.

Referring to fig. 1-7, a cleaning apparatus 10 according to an embodiment of the present application is illustrated, and the cleaning apparatus 10 may be a floor sweeping robot, a floor mopping robot, or a floor sweeping and mopping robot.

The cleaning device 10 includes a device body and a drive assembly. The apparatus main body is a housing structure, and each component in the cleaning apparatus 10 is directly or indirectly provided to or connected with the apparatus main body. The drive assembly may include a road wheel and a guide wheel rotatably coupled to the apparatus body for driving the apparatus body over a surface to be cleaned.

The cleaning apparatus 10 further includes a dust suction fan provided in the apparatus main body, a dust box assembly 100 detachably connected to the apparatus main body, and a dust suction port provided in the apparatus main body. The dust collection fan is connected with the dust box assembly 100 and is used for generating negative pressure in the dust box assembly 100, one end of the dust collection opening is communicated with the dust box assembly 100, and the other end of the dust collection opening faces the surface to be cleaned, so that when the dust collection fan works, garbage such as dust on the surface to be cleaned can be absorbed into the dust box assembly 100 through the dust box assembly 100 and the dust collection opening and stored.

In the present embodiment, the dust box assembly 100 includes a dust box body 110, a dust entry cover plate 120, a dust entry cover plate 130, a dust exit cover plate 140, an actuator 150, and a limiter 160.

The dust box body 110 is a housing structure having a dust collection chamber 111 and a dust inlet 112, an air inlet 113 and a dust outlet 114 communicating with the dust collection chamber 111. The dust collection chamber 111 is a receiving chamber that can receive debris such as dust. Wherein the dust inlet 112 communicates with a first end of a dust suction opening in the cleaning apparatus 10, when the dust suction fan is operated, a negative pressure is generated in the dust collection chamber 111, and dust such as dust from a surface to be cleaned enters the dust collection chamber 111 through the dust inlet 112 and is temporarily stored in the dust collection chamber 111. The air inlet 113 communicates with the outside of the cleaning apparatus 10, for example through a gas flow passage in the apparatus body, and air from the outside of the cleaning apparatus 10 can enter the dust collection chamber 111 through the air inlet 113. The dust outlet 114 communicates with the outside of the cleaning apparatus 10, and the gas entering the dust collection chamber 111 through the gas inlet 113 can blow the dust such as dust in the dust collection chamber 111 toward the dust outlet 114, so that the dust leaves the dust collection chamber 111 through the dust outlet 114, thereby cleaning the dust in the dust collection chamber 111. In this embodiment, the dust inlet 112, the air inlet 113 and the dust outlet 114 are located on a first side, a second side and a third side of the accommodating cavity, respectively, wherein the second side and the third side are opposite sides, and the first side is adjacent to the second side and the third side. Referring to fig. 7, the air inlet 113 and the dust outlet 114 are respectively located at both ends of the dust collection chamber 111, so that the air entering the dust collection chamber 111 from the air inlet 113 can blow the dust such as dust in the dust collection chamber 111 from one end of the dust collection chamber 111 to the dust outlet 114 at the other end of the dust collection chamber 111, the air flow can smoothly circulate in the dust collection chamber 111, and there is almost no dead angle, so that the dust in the dust collection chamber 111 can be effectively cleaned. In the embodiment of the present application, the air inlet 113 and the dust outlet 114 are located at both sides in the length direction of the dust collection chamber 111, that is, the air inlet 113 and the dust outlet 114 may be located at both ends of the dust collection chamber 111 farthest from each other. Note that, the top of the dust collecting chamber 111 (i.e., the upper portion of the dust collecting chamber 111 in fig. 7) is closed, and the top of the dust collecting chamber 111 is not shown in fig. 1 and other drawings for better illustrating the structure inside the dust collecting chamber 111.

The dust inlet cover 120 is rotatably connected to the dust box body 110, and is located at a side of the dust inlet 112 facing the dust collecting chamber 111 (i.e., located at an inner side of the dust collecting chamber 111) for opening or closing the dust inlet 112. In this embodiment, the dust inlet cover 120 is provided with a first rotating shaft 121, the first rotating shaft 121 is located at two sides of the dust inlet cover 120, and the dust inlet cover 120 is rotatably connected to the dust box body 110 through the first rotating shaft 121. The inside of the dust collection chamber 111 is fixedly provided with a sleeve portion corresponding to the first rotation shaft 121, and the first rotation shaft 121 is penetrated into the sleeve portion so as to be rotatably connected to the dust box body 110. When the dust inlet cover plate 120 is at a first angle relative to the dust box body 110 (i.e., when the first rotating shaft 121 is at the first angle), the dust inlet 112 is covered by the dust inlet cover plate 120, and the peripheral edge of the dust inlet cover plate 120 is attached to the dust box body 110 at the peripheral edge of the dust inlet 112, so that the dust inlet 112 is closed. When the dust inlet cover plate 120 rotates from the first angle to the second angle (i.e., when the first rotating shaft 121 is at the second angle) relative to the dust box body 110, the peripheral edge of the dust inlet cover plate 120 is separated from the dust box body 110 at the peripheral edge of the dust inlet 112, so that the dust inlet 112 is opened. In the embodiment of the present application, the first rotating shaft 121 is located on a side of the dust inlet 112 away from the surface to be cleaned, so that in a normal condition (such as a condition that the air pressure inside and outside the dust collecting cavity 111 is balanced), the dust inlet cover plate 120 is at a first angle relative to the dust box body 110 under the action of gravity, and the dust inlet 112 is closed.

The air inlet cover 130 is rotatably connected to the dust box body 110, and is located at a side of the air inlet 113 facing the dust collection chamber 111 (i.e., located at an inner side of the dust collection chamber 111) for opening or closing the air inlet 113. In the embodiment of the present application, the air inlet cover 130 is provided with a second rotating shaft 131 and a connecting rod 133, and the air inlet cover 130 is rotatably connected to the dust box body 110 through the second rotating shaft 131. The dust box body 110 outside the dust collection cavity 111 is fixedly provided with a sleeve part corresponding to the second rotating shaft 131, the second rotating shaft 131 is arranged in the sleeve part in a penetrating way, one end of the connecting rod 133 is connected with the second rotating shaft 131, and the other end of the connecting rod passes through the air inlet 113 to be connected with the air inlet cover plate 130 positioned in the dust collection cavity 111, so that the air inlet cover plate 130 is rotatably connected with the dust box body 110. When the air inlet cover plate 130 is at the third angle relative to the dust box body 110, the air inlet 113 is covered by the air inlet cover plate 130, and the circumferential edge of the air inlet cover plate 130 is attached to the dust box body 110 at the circumferential edge of the air inlet 113, so that the air inlet 113 is closed. When the air inlet cover 130 rotates from the third angle to the fourth angle with respect to the dust box body 110, the circumferential edge of the air inlet cover 130 is separated from the dust box body 110 at the circumferential edge of the air inlet 113, thereby opening the air inlet 113. In the present embodiment, the air inlet cover 130 is configured to rotate to a side away from the surface to be cleaned to open the air inlet 113, so that in a normal case, the air inlet cover 130 is at a third angle with respect to the dust box body 110 under the action of gravity, and the air inlet 113 is closed.

The dust outlet cover 140 is rotatably connected to the dust box body 110, and is located on a side of the dust outlet 114 away from the dust collecting chamber 111 (i.e. located on an outer side of the dust collecting chamber 111) for opening or closing the dust outlet 114. In the embodiment of the present application, a third rotating shaft (not shown) is disposed on the dust cover plate 140, and the dust cover plate 140 is rotatably connected to the dust box body 110 through the third rotating shaft. A sleeve portion (not shown) corresponding to the third rotating shaft is fixedly disposed on the dust box body 110 outside the dust collecting cavity 111, and the third rotating shaft is inserted into the sleeve portion, so that the dust outlet cover plate 140 is rotatably connected to the dust box body 110. When the dust cover plate 140 is at a fifth angle relative to the dust box body 110, the dust cover plate 140 covers the dust outlet 114, and the peripheral edge of the dust cover plate 140 is attached to the dust box body 110 at the peripheral edge of the dust outlet 114, so that the dust outlet 114 is closed. When the dust cover plate 140 rotates from the fifth angle to the sixth angle relative to the dust box body 110, the peripheral edge of the dust cover plate 140 is separated from the dust box body 110 at the peripheral edge of the dust outlet 114, so that the dust outlet 114 is opened. In this embodiment, the third rotating shaft is located at a side of the dust outlet 114 away from the surface to be cleaned, so that under normal conditions, the dust outlet cover plate 140 is at a fourth angle relative to the dust box body 110 under the action of gravity, the dust outlet 114 is closed, and because the dust outlet cover plate 140 is disposed outside the dust collecting cavity 111, when the inside of the dust collecting cavity 111 is normal pressure (one atmosphere) or negative pressure (or when the air pressure in the dust collecting cavity 111 is less than or equal to the air pressure at the dust outlet cover plate 140 of the dust collecting cavity 111), the dust outlet cover plate 140 closes the dust outlet 114, and when the inside of the dust collecting cavity 111 is positive pressure (or when the air pressure in the dust collecting cavity 111 is greater than the air pressure at the dust outlet cover plate 140 of the dust collecting cavity 111), the dust outlet cover plate 140 opens the dust outlet 114. Specifically, when the cleaning apparatus 10 cleans a surface to be cleaned, the dust suction fan operates, which may generate a negative pressure in the dust collection chamber 111 (the dust collection chamber 111 may have an opening communicating with the dust suction fan), and dust such as dust from the surface to be cleaned may enter the dust collection chamber 111 through the dust inlet 112, and at this time, the dust outlet cover 140 closes the dust outlet 114, and the dust in the dust collection chamber 111 may not leak through the dust outlet 114. When the base station collects dust on the cleaning device 110, the base station can generate negative pressure at the dust outlet cover plate 140 of the dust collecting cavity 111, at this time, the air pressure in the dust collecting cavity 111 is greater than the air pressure at the dust outlet cover plate 140 of the dust collecting cavity 111, the dust outlet cover plate 140 opens the dust outlet 114, and the garbage in the dust collecting cavity 111 can leave the dust collecting cavity 111 through the dust outlet 114 to enter the base station.

The actuating member 150 is connected to the limiting member 160 for driving the limiting member 160 to switch between the first position and the second position. In the embodiment of the present application, the actuating member 150 and the limiting member 160 are disposed outside the dust collecting chamber 111, adjacent to the junction of the first side and the second side of the dust collecting chamber 111. The actuator 150 may be an electric actuator, such as a motor (e.g., a linear motor or a rotary motor), an electromagnetic actuator (e.g., a solenoid valve or a linear solenoid), etc., which may be directly connected to the stopper 160 or drivingly connected through a transmission structure to drive the stopper 160 between the first position and the second position. In other embodiments, the actuator 150 may also be a pneumatic actuator, such as a cylinder or the like. The dust box body 110 may be provided with a receiving groove for receiving the actuating member 150, and the actuating member 150 may be received in the receiving groove and detachably fixed to the dust box body 110 by a screw or other suitable means.

In this embodiment, the actuating member 150 is configured to move the limiting member 160 along a preset direction (i.e. up-down direction in fig. 3) to switch between the first position and the second position, where the limiting member 160 is configured to limit the air inlet cover 130 from opening the air inlet 113 when in the first position, and to limit the dust inlet cover 120 from opening the dust inlet 112 when in the second position. The middle part of the limiting member 160 is connected with the actuating member 150, and when the limiting member 160 is at the first position, the first end of the limiting member 160 abuts against the air inlet cover plate 130, so that the air inlet cover plate 130 is limited to rotate relative to the dust box body 110, the air inlet cover plate 130 is kept at a third angle relative to the dust box body 110 and cannot rotate from the third angle to a fourth angle, and accordingly, the air inlet cover plate 130 is limited to open the air inlet 113, and the air inlet cover plate 130 is kept in a state of closing the air inlet 113. The second end of the limiting member 160 abuts against the dust inlet cover plate 120 when the limiting member 160 is at the second position, so as to limit the rotation of the dust inlet cover plate 120 relative to the dust box body 110, so that the dust inlet cover plate 120 is kept at a first angle relative to the dust box body 110 and cannot rotate from the first angle to a second angle, and therefore, the dust inlet cover plate 120 is limited to open the dust inlet 112, and the dust inlet cover plate 120 is kept in a state of closing the dust inlet 112. It should be noted that, when the limiting member 160 is at the first position, the second end of the limiting member 160 does not abut against the dust inlet cover plate 120, and does not limit the rotation of the dust inlet cover plate 120 relative to the dust box body 110, and at this time, the dust inlet cover plate 120 may rotate relative to the dust box body 110 to open or close the dust inlet 112; the first end of the limiting member 160 does not abut against the air inlet cover plate 130 when the limiting member 160 is in the second position, and does not limit the rotation of the air inlet cover plate 130 relative to the dust box body 110, at this time, the air inlet cover plate 130 can rotate relative to the dust box body 110 to open or close the air inlet 113.

Specifically, in the embodiment of the present application, a first limiting portion 122 is fixedly disposed on a first rotating shaft 121 of the dust inlet cover plate 120, and the first limiting portion 122 is plate-shaped and is located outside the dust collecting chamber 111, and rotates synchronously with the dust inlet cover plate 120. Referring to fig. 3, when the stopper 160 is in the first position, the second end of the stopper 160 (i.e., the right end of the stopper 160 in fig. 3) is not in contact with the first stopper 122, and the first stopper 122 can rotate relative to the dust box body 110, so that the dust inlet cover 120 can rotate relative to the dust box body 110 to open or close the dust inlet 112. Referring to fig. 5, when the limiting member 160 is at the second position (and the dust inlet cover 120 is at the first angle), the second end of the limiting member 160 abuts against the first limiting portion 122, so as to limit the rotation of the first limiting portion 122, thereby limiting the rotation of the dust inlet cover 120 relative to the dust box body 110, so that the dust inlet 112 cannot be opened, and the dust inlet 112 is kept at a position where the dust inlet 112 is closed.

A second limiting part 132 is fixedly arranged on the second rotating shaft 131 of the air inlet cover plate 130, is positioned outside the dust collection cavity 111 and rotates synchronously with the air inlet cover plate 130. The second limiting portion 132 is in a U-shape, and forms an elongated opening together with the second rotating shaft 131, and the first end of the limiting member 160 has a bending portion, and the bending portion can extend into the opening. Referring to fig. 3, when the stopper 160 is at the first position (and the air inlet cover 130 is at the third angle), the bent portion of the first end of the stopper 160 (i.e., the left end of the stopper 160 in fig. 3) abuts against the end of the opening away from the second rotating shaft 131 (i.e., the lower end of the opening in fig. 3), and the rotation of the second stopper 132 relative to the dust box body 110 is limited, so that the rotation of the air inlet cover 130 relative to the dust box body 110 is limited, and the air inlet 113 cannot be opened. Referring to fig. 5, when the limiting member 160 is in the second position, the bent portion of the first end of the limiting member 160 corresponds to the opening, and the bent portion may extend into the opening when the air inlet cover 130 rotates, so that the second limiting portion 132 is not limited from rotating relative to the dust box body 110, and thus, the air inlet cover 130 may rotate relative to the dust box body 110 to open or close the air inlet 113. It should be noted that, the shapes of the first limiting portion 122 and the second limiting portion 132 are not limited to a plate shape or a U-shaped rod shape, and those skilled in the art may set the shapes according to the needs, as long as the limiting member 160 can limit the air inlet cover 130 to open the air inlet 113 and the dust inlet cover 120 to open the dust inlet 112 when in the first position and the second position, respectively.

In this embodiment, the actuating member 150, the limiting member 160, the first limiting portion 122 and the second limiting portion 132 are all located outside the dust collecting cavity 111, so that the contact between the actuating member 150 and the dust collecting cavity 111 and the contact between the actuating member and the dust collecting cavity 111 and the normal action of the dust collecting cavity 111 due to the dust can be effectively avoided.

In other embodiments, the actuator may be configured to rotate the limiter about the preset axis to switch between the first position and the second position. Specifically, the actuating member may be a rotating motor, and the limiting member may be in a rod shape, wherein the first end is a free end, and the second end is connected to an output shaft of the rotating motor, so that the actuating member may drive the limiting member to rotate around the output shaft to switch between the first position and the second position. When the limiting member rotates to the first position, the first end of the limiting member abuts against the air inlet cover plate 130 (or the second limiting portion 132), so as to limit the rotation of the air inlet cover plate 130 relative to the dust box body 110, and at this time, the dust inlet cover plate 120 can rotate relative to the dust box body 110 to open or close the dust inlet 112. When the limiting member rotates to the second position, the first end of the limiting member abuts against the dust inlet cover plate 120 (or the first limiting portion 122), so as to limit the rotation of the dust inlet cover plate 120 relative to the dust box body 110, and at this time, the air inlet cover plate 130 can rotate relative to the dust box body 110 to open or close the air inlet 113.

For the dust box assembly 100 of the embodiment of the application, when the cleaning device 10 cleans a surface to be cleaned, the actuating member 150 can be controlled to drive the limiting member 160 to move to the first position, at this time, the limiting member 160 limits the air inlet cover plate 130 to open the air inlet 113, the air inlet 113 is closed, and when the dust suction fan in the cleaning device 10 works, negative pressure is generated in the dust collection cavity 111. Since the dust outlet cover plate 140 is disposed outside the dust collecting chamber 111 and can only be opened outwards, the dust outlet cover plate 140 can close the dust outlet 114 when negative pressure is generated in the dust collecting chamber 111. At this time, the dust inlet cover 120 may be rotated from a third angle to a fourth angle with respect to the dust box body by the dust suction fan, thereby opening the dust inlet 112, and dust such as dust from the surface to be cleaned may be introduced into the dust collection chamber 111 through the dust inlet 112 and temporarily stored in the dust collection chamber 111.

Referring to fig. 7, when the dust box assembly 100 is collected by the base station, the actuating member 150 may be controlled to drive the limiting member 160 to move to the second position, and the limiting member 160 limits the dust inlet cover 120 to open the dust inlet 112 when in the second position, so that the dust inlet 112 is closed. At this time, the base station only needs to generate suction force outside the dust outlet 114, so that the dust outlet cover plate 140 located outside the dust outlet 114 can be sucked open (the dust outlet 114 is opened when the air pressure in the dust collecting cavity 111 is greater than the air pressure at the dust outlet cover plate 140 of the dust collecting cavity 111, the dust outlet 114 is opened, the garbage in the dust collecting cavity 111 can leave the dust collecting cavity 111 from the dust outlet 114 to enter the base station, and the air inlet cover plate 130 is located inside the dust collecting cavity 111 and the rotation of the air inlet cover plate 130 is not limited at this time by the limiting piece 160, so that the air inlet cover plate 130 can be sucked open, external air (or gas blown by the base station) can enter the dust collecting cavity 111 from the air inlet 113, and the garbage in the dust collecting cavity 111 is pushed to leave from the dust outlet 114 to enter the base station, so that the garbage is prevented from remaining in the dust collecting cavity 111. And because the air inlet 113 and the dust outlet 114 are positioned on two opposite sides in the dust collection cavity 111, the air flow can smoothly flow in the dust collection cavity 111, the difference between the air flow and the air pressure at each position of the dust collection cavity 111 is small, and the air flow is more uniform, so that the garbage in the dust collection cavity 111 can more efficiently leave the dust collection cavity 111, and the garbage residue is avoided. And at this time, the limiting member 160 limits the dust inlet cover plate 120 to open the dust inlet 112, and the dust inlet 112 is closed, so that the garbage in the dust collecting chamber 111 does not leak through the dust inlet 112.

A cleaning system according to an embodiment of the present application, which includes the cleaning apparatus 10 and the base station 20 described above, is exemplarily described with reference to fig. 8.

The base station 20 is provided with a dust collection assembly, a dust collection port 22 and an air blowing port 21, the dust collection port 22 is used for communicating with a dust outlet 114 of the dust box assembly 100, the air blowing port 21 is used for communicating with an air inlet 113 of the dust box assembly 100, the dust collection assembly is used for blowing air into the dust collection cavity 111 through the air blowing port 21 and the air inlet 113, and the dust collection assembly is used for sucking garbage in the dust collection cavity 111 through the dust collection port 22 and the dust outlet 114. The communication between the dust collecting port 22 and the dust outlet 114, and between the air blowing port 21 and the air inlet 113 may be direct butt joint, or may be through a gas flow passage provided in the dust box body 110 and/or the apparatus main body. The dust collection assembly may include a base station fan and a base station dust box, one end of the base station fan is communicated with the air blowing port 21, and the other end is communicated with the dust collection port 22 through the base station dust box, so that the base station fan can suck the garbage in the dust collection cavity 111 into the base station dust box for storage when working. In some embodiments, the air outlet 21 may be disposed directly on the base station blower and the dust collection port 22 may be disposed directly on the base station dust box.

When the base station 20 collects dust, the actuating member 150 can be controlled to drive the limiting member 160 to move to the second position, and the limiting member 160 limits the dust inlet cover plate 120 to open the dust inlet 112 when in the second position, and the dust inlet 112 is closed, at this time, the base station fan can blow air to the air inlet 113 of the dust box assembly 100 through the air blowing port 21, positive pressure is generated at the air inlet 113, air is sucked outside the dust outlet 114 through the dust collecting port 22, and negative pressure is generated at the dust outlet 114. The dust cover plate 140 and the air inlet cover plate 130 of the cleaning apparatus 10 are opened by the combined action of the negative pressure generated by the suction and the positive pressure generated by the blowing. The garbage in the dust collection cavity 111 enters the dust collection port 22 of the base station 20 through the dust outlet 114 under the action of the circulating air flow, and is collected by the base station dust box. Because the dust inlet cover plate 120 is limited by the limiting piece 160 so that the dust inlet 112 cannot be opened, the leakage of air pressure from the dust inlet 112 can be effectively avoided, the suction force is increased, the dust collection effect is improved, and the leakage of garbage in the dust collection cavity 111 from the dust inlet 112 can be effectively avoided.

In some embodiments, the base station 20 may be provided with a dust collection assembly and a dust collection port 22 without the air blowing port 21. When the base station 20 collects dust, the actuating member 150 can be controlled to drive the limiting member 160 to move to the second position, and the limiting member 160 limits the dust inlet cover plate 120 to open the dust inlet 112 when in the second position, and the dust inlet 112 is closed, at this time, the base station fan can suck air outside the dust outlet 114 through the dust collecting opening 22, so that the dust outlet cover plate 140 outside the dust outlet 114 is sucked open, the dust outlet 114 is opened, and the garbage in the dust collecting cavity 111 enters the base station 20 from the dust outlet 114. Since the air inlet cover 130 is located inside the dust collecting cavity 111 and the rotation of the air inlet cover 130 is not limited by the limiting member 160, the air inlet cover 130 is also sucked open, and the external air enters the dust box from the air inlet 113, so that the garbage in the dust collecting cavity 111 is pushed to leave from the dust outlet 114 and enter the dust collecting opening 22 of the base station 20 and further enter the dust box of the base station. Because the air inlet 113 and the dust outlet 114 are positioned on two opposite sides of the dust collection cavity 111, the air flow can smoothly flow in the dust collection cavity 111, the difference between the air flow and the air pressure at each position of the dust collection cavity 111 is small, and the air flow is more uniform, so that the garbage in the dust collection cavity 111 can leave the dust collection cavity 111 more efficiently, and the garbage residue is avoided. And at this time, the limiting member 160 limits the dust inlet cover plate 120 to open the dust inlet 112, and the dust inlet 112 is closed, so that the garbage in the dust collecting chamber 111 does not leak through the dust inlet 112.
