The exemplary embodiments according to the present disclosure will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in various different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present disclosure thorough and complete, and to fully convey the concepts of these exemplary embodiments to those skilled in the art.
As shown in Fig. 1 to Fig. 19, embodiments of the present disclosure provide a base station 200 and a cleaning robot system. The cleaning robot system includes a self-moving cleaning device 100 and the base station 200, i.e., the base station 200 and the self-moving cleaning device 100 are used in cooperation.
Further, as shown in Fig. 1 and Fig. 2, the self-moving cleaning device 100 may include a machine main body 110, a perception system 120, a control module, a driving system 140, a cleaning system 150, an energy system and a human-machine interaction system 170. It can be understood that the self-moving cleaning device 100 may be a self-cleaning device or other self-moving cleaning devices 100 that meet requirements. The self-moving cleaning device 100 is a device that automatically performs, without user operations, a cleaning operation in a certain region to be cleaned. When the self-moving cleaning device 100 starts to work, the self-moving cleaning device 100 starts from the base station 200 to perform a cleaning task. When the self-moving cleaning device 100 completes the cleaning task or needs to stop the cleaning task, the self-moving cleaning device 100 may return to the base station 200 for operations such as charging, and/or water replenishing, and/or washing, and/or dust collection.
As shown in Fig. 1, the machine main body 110 includes a forward portion 111 and a rearward portion 112, is approximately circular, and may also be in other shapes including, but not limited to, an approximately D shape with a square front and a circular rear, and a rectangular or square shape with a square front and a square rear.
As shown in Fig. 1, the perception system 120 includes a position determining apparatus 121 located on the machine main body 110, a collision sensor and a proximity sensor both arranged on a buffer 122 of the forward portion 111 of the machine main body 110, a cliff sensor arranged at a lower portion of the machine main body 110, and a magnetometer, an accelerometer, a gyroscope and an odograph and other sensing apparatuses arranged inside the machine main body 110, for providing various position information and motion status information of a machine to the control module. The position determining apparatus 121 includes, but is not limited to, a camera and a laser distance sensor (LDS).
As shown in Fig. 1, the forward portion 111 of the machine main body 110 may carry the buffer 122. When a driving wheel module 141 propels the self-moving cleaning device 100 to travel on the ground in the process of cleaning, the buffer 122 detects one or more events in a travel path of the self-moving cleaning device 100 via a sensor system arranged thereon, for example, an infrared sensor. The self-moving cleaning device 100 may control, based on the events (e.g., an obstacle and a wall) detected by the buffer 122, the driving wheel module 141 to enable the self-moving cleaning device 100 to respond to the event, for example, by moving away from the obstacle.
The control module is arranged on a main circuit board inside the machine main body 110 and includes a computing processor, such as a central processing unit and an application processor, in communication with a non-transitory memory, such as a hard disk, a flash memory and a random access memory. The application processor is configured to draw a simultaneous map of an environment where the self-moving cleaning device 100 is located based on obstacle information fed back by the laser distance sensor by use of a positioning algorithm, for example, simultaneous localization and mapping (SLAM). In addition, by combining the distance information and speed information fed back by the sensors, the cliff sensor, the magnetometer, the accelerometer, the gyroscope, the odograph, and other sensing apparatuses arranged on the buffer 122, a comprehensive judgment may be made on a current working status and a current position of the self-moving cleaning device 100, as well as a current posture of the self-moving cleaning device 100, such as crossing a doorsill, moving onto a carpet, being at a cliff, being stuck from above or below, having a full dust box, being picked up, etc. For different cases, specific next action strategies will be given, such that the operation of the self-moving cleaning device 100 is more in line with the requirements of an owner, thereby providing better user experience.
As shown in Fig. 2, the driving system 140 may manipulate the machine main body 110 to travel across the ground based on a driving command with distance and angle information, such as components of x, y and theta. The driving system 140 includes a driving wheel module 141, and the driving wheel module 141 may control both of a left wheel and a right wheel simultaneously. In order to control the movement of the machine more accurately, the driving wheel module 141 preferably includes a left driving wheel module and a right driving wheel module, which are arranged along a transverse axis defined by the machine main body 110. In order to enable the self-moving cleaning device 100 to move more stably or have a better movement ability on the ground, the self-moving cleaning device 100 may include one or more driven wheels 142, and the driven wheels 142 include but are not limited to universal wheels. The driving wheel module 141 includes a traveling wheel, a driving motor and a control circuit for controlling the driving motor. The driving wheel module 141 may also be connected to an odograph, and a circuit for measuring a driving current. A driving wheel may be provided with an offset drop suspension system, which is fastened movably to (e.g., attached rotatably to) the machine main body 110, and receives a spring offset biased downward and away from the machine main body 110. The spring offset allows the driving wheel to maintain contact and traction with the ground with a certain landing force, while cleaning elements 183 of the self-moving cleaning device 100 are also in contact with the ground with certain pressure.
The energy system includes a rechargeable battery, such as a nickel-metal hydride battery and a lithium battery. The rechargeable battery may be connected to a charging control circuit, a battery pack charging temperature detecting circuit, and a battery undervoltage monitoring circuit which are then connected to a single chip microcomputer control circuit. A main unit is connected to the base station 200 through a charging electrode arranged on one side or below the machine body for charging.
The human-machine interaction system 170 includes buttons on a panel of the main unit for a user to select functions, and may further include a display screen and/or an indicator light and/or a horn. The display screen, the indicator light or the horn presents a current status or function options of the self-moving cleaning device to the user. The human-machine interaction system may further include a mobile phone client program. For a route navigation type self-moving cleaning device 100, a mobile phone client may show the user a map of the environment where the device is located, as well as a position of the device, thereby providing the user with richer and more user-friendly function items.
As shown in Fig. 2, the cleaning system 150 includes a dry cleaning system 151, i.e., the self-moving cleaning device 100 may be a sweeper, or the cleaning system 150 includes a wet cleaning system and a dry cleaning system 151, i.e., the self-moving cleaning device 100 may be a sweeping and mopping integrated machine. The wet cleaning system includes at least one cleaning element 183, and the cleaning element 183 may be a mop plate or other wet cleaning members.
As shown in Fig. 2, the dry cleaning system 151 according to the embodiment of the present disclosure may include a rolling brush, a dust box and a dust suction fan. The rolling brush having a certain interference with the ground sweeps up debris on the ground and rolls the debris up to the front of a dust suction port between the rolling brush and the dust box, and after that, the debris is sucked into the dust box by an airflow having a suction force that is generated by the dust suction fan and passes through the dust box. The dry cleaning system 151 may further include a side brush 152 having a rotating shaft, and the rotating shaft is angled relative to the ground for moving particles into a rolling brush region of the cleaning system 150.
The dust box 160 according to the embodiments of the present disclosure is detachably connected to the machine main body 110 of the self-moving cleaning device 100, such that the dust box 160 can be detached from the machine main body 110 of the self-moving cleaning device 100 for cleaning or maintenance, and the dust box 160 can be conveniently and quickly mounted on the machine main body 110 for a dust suction operation, which is simple and easy to operate and convenient to use.
As shown in Fig. 3, Fig. 4, Fig. 5, and Fig. 6, the dust box 160 of the self-moving cleaning device 100 according to the embodiments of the present disclosure is provided with a debris storage chamber 162, and an air inlet 163 and a dust exhaust port 164 that are communicated with the debris storage chamber 162. The dust box 160 is also provided with a dust inlet 166 and an air vent port 1601 that are communicated with the debris storage chamber 162. The dust inlet 166 is communicated with a dust suction port of the self-moving cleaning device 100 through a dust suction duct. The dust suction fan of the self-moving cleaning device 100 is communicated with the air vent port 1601 of the dust box 160. A filtering part 161 is arranged at the air vent port 1601. A suction airflow generated by operation of the dust suction fan can suck debris on a surface to be cleaned into the dust box 160 through the dust suction port, the dust suction duct and the dust inlet 166, and after being filtered by the filtering part 161 at the air vent port 1601, the dust suction airflow is discharged from the air vent port 1601 through the dust suction fan. Therefore, the debris can be collected in the dust box 160, and the provided filtering part 161 can prevent the debris inside the dust box 160 from entering the dust suction fan, which in turn is conducive to prolonging the service life of the dust suction fan.
It should be noted that, as shown in Fig. 3, the machine main body 110 of the self-moving cleaning device 100 is also provided with a dust outlet 169, the interior of machine main body 110 is provided with a dust exhaust channel 168 communicating the dust exhaust port 164 to the dust outlet 169. The base station 200 is provided with a dust collection port 2115 and a dust collection assembly 260 communicated with the dust collection port 2115. When the self-moving cleaning device 100 is docked at the base station 200, and after the dust outlet 169 of the self-moving cleaning device 100 is butted with the dust collection port 2115 on the base station 200, the dust collection assembly 260 on the base station 200 works, and the airflow enters through the air inlet 163 of the dust box 160, passes through the dust exhaust port 164, the dust exhaust channel 168, and flows into the base station 200 through the dust outlet 169 and the dust collection port 2115 which are butted, such that the debris in the dust box 160 can be collected within the base station 200, thereby achieving the dust collection operation.
One-way valves are arranged at the air inlet 163 of the dust box 160 and the dust exhaust port 164 of the dust box 160. When cleaning impurities in the dust box 160, namely, during the dust collection operation on the self-moving cleaning device 100 by the base station 200, the valves at the air inlet 163 and the dust exhaust port 164 of the dust box 160 are both opened, such that the airflow generated in the dust box 160 can carry away the impurities more easily.
In a specific example, the filter part 161 is detachably connected to the dust box 160. After the dust box 160 is disassembled from the machine main body 110 of the self-moving cleaning device 100, the filter part 161 may be disassembled from the dust box 160 to clean the debris in the dust box 160 or wash the dust box through the air vent port 1601.
In another specific example, the dust box 160 includes a top wall, a bottom wall, and a dust box sidewall. The debris storage chamber 162 has an opening, for example, the opening of the debris storage chamber is defined by the dust box sidewall, and the top wall of the dust box is arranged to be movably connected to the dust box sidewall to open or close the opening of the debris storage chamber. After the dust box 160 is disassembled from the machine main body 110 of the self-moving cleaning device 100, the opening of the debris storage chamber can be opened through the top wall of the dust box, and thus, the dust box 160 can be cleaned, such as washing the dust box 160 or dumping out debris in the dust box 160, or maintaining the dust box 160. After the top wall of the dust box closes the opening of the debris storage chamber, the dust box 160 is mounted on the machine main body 110, and then the dust suction operation can be performed.
As shown in Fig. 4 and Fig. 6, in the dust box 160 according to the embodiment of the present disclosure, the dust exhaust port 164 is formed on the sidewall of the debris storage chamber 162, and the sidewall of the debris storage chamber 162 where the dust exhaust port 164 is located is obliquely arranged with respect to other sidewalls of the debris storage chamber 162 in the circumferential direction, wherein the circumferential side of the debris storage chamber 162 may be understood as the circumferential side of the opening of the debris storage chamber. In other words, the dust exhaust port 164 is arranged on one sidewall on the circumferential side of the opening of the debris storage chamber 162, and this sidewall is obliquely arranged with respect to other sidewalls on the circumferential side of the opening of the debris storage chamber 162, such that the plane where the dust exhaust port 164 is located is obliquely arranged with respect to other sidewalls of the debris storage chamber 162 in the circumferential direction, thereby improving the smoothness of exhausting the airflow in the dust box 160 through the dust exhaust port 164 and improving the flowing efficiency of the airflow in the dust box 160.
As shown in Fig. 3 and Fig. 6, by arranging a flow guide member 165 in the debris storage chamber 162, the airflow flowing into the air inlet 163 is guided to the dust exhaust port 164 by the flow guide member 165, which can further avoid the problem that the debris in the dust box 160 is gathered at the corner of the debris storage chamber 162 and not collected. Thus, it is beneficial for improving the thoroughness of collecting the debris in the dust box 160 to the base station 200 and improving a dust collection effect.
In the above embodiment, the flow guide member 165 is of an arc-shaped structure, and the arc-shaped flow guide member 165 has a better guiding effect on the airflow, which can further improve the smoothness of exhausting the airflow in the dust box 160 through the dust exhaust port 164, and improve the flowing efficiency of the airflow in the dust box 160. In addition, the occurrence of debris gathering on the flow guide member 165 is reduced, which is beneficial for further improving the thoroughness of collecting the debris in the dust box 160 to the base station 200.
As shown in Fig. 3 and Fig. 6, a windward surface 1651 of the flow guide member 165 has a concave arc shape, and the provided concave arc shape can increase a flowing space of the airflow between the air inlet 163 and the dust exhaust port 164 to a certain extent, which is beneficial for improving the flowing smoothness of the airflow in the dust box 160. In addition, the concave arc-shaped windward surface 1651 can smoothly guide the airflow flowing into the air inlet 163 to the dust exhaust port 164, and further, the debris in the dust box 160 can be guided to the dust exhaust port 164 along with the airflow, which is beneficial for improving the dust collection effect.
As shown in Fig. 3 and Fig. 6, in some possible embodiments according to the present disclosure, a first end of the flow guide member 165 is connected to the sidewall of the debris storage chamber 162 at the dust exhaust port 164, and a second end of the flow guide member 165 extends towards a direction close to the air inlet 163 and is connected to a sidewall of the debris storage chamber 162. In other words, the flow guide member 165 also plays the role of a baffle. The inner space of the dust box 160 may be divided into two cavities which are isolated from each other by the flow guide member 165, and the air inlet 163 and the dust exhaust port 164 are located in the cavity where the windward surface 1651 of the flow guide member 165 is located. Or, in some examples, the dust box 160 may be arranged to be an irregular shape, and one sidewall of the dust box 160 may be arranged as the flow guide member 165. Thus, the airflow flowing into the air inlet 163 can be smoothly guided to the dust exhaust port 164 by using the flow guide member 165, so as to avoid the problem that the debris is gathered and cannot be collected conveniently caused by the fact that the airflow flowing into the cavity or the position where the leeward surface 1652 of the flow guide member 165 is located cannot be smoothly exhausted through the dust exhaust port 164, and the thoroughness of collecting the debris in the dust box 160 to the base station 200 is greatly improved.
In addition, the windward surface 1651 of the flow guide member 165 has a concave arc shape, such that the connecting positions between two end parts of the flow guide member 165 and the sidewall of the debris storage chamber 162 form larger angles, which can reduce or avoid the phenomenon of debris gathering.
As shown in Fig. 4, Fig. 5 and Fig. 6, in some possible embodiments according to the present disclosure, the sidewalls of the debris storage chamber 162 include a first dust box sidewall 1611, a second dust box sidewall 1612, a third dust box sidewall 1613, a fourth dust box sidewall 1614 and a fifth dust box sidewall 1615 which are connected in sequence. The first dust box sidewall 1611 and the third dust box sidewall 1613 are oppositely arranged. The second dust box sidewall 1612 and the fifth dust box sidewall 1615 are oppositely arranged. The fourth dust box sidewall 1614 is connected between the third dust box sidewall 1613 and the fifth dust box sidewall 1615 and obliquely arranged with respect to the third dust box sidewall 1613 and the fifth dust box sidewall 1615. The dust exhaust port 164 is formed on the fourth dust box sidewall 1614. Thus, it can be ensured that the fourth dust box sidewall 1614 where the dust exhaust port 164 is located is obliquely arranged with respect to the first dust box sidewall 1611, the second dust box sidewall 1612, the third dust box sidewall 1613 and the fifth dust box sidewall 1615. That is, the dust exhaust port 164 is obliquely arranged relative to the first dust box sidewall 1611, the second dust box sidewall 1612, the third dust box sidewall 1613 and the fifth dust box sidewall 1615, which is beneficial for the smoothness of exhausting the airflow in the dust box 160 through the dust exhaust port 164.
An inclination angle between the fourth dust box sidewall 1614 and the third dust box sidewall 1613 is more than 90 degrees and less than 180 degrees, such that the inclination angle between the sidewall of the dust box 160 of the debris storage chamber 162 where the dust exhaust port 164 is located and the adjacent sidewall of the dust box 160 of the debris storage chamber 162 is larger, which facilitates the flowing of the airflow and can reduce the gathering of the debris at the connecting position between the fourth dust box sidewall 1614 and the third dust box sidewall 1613 and at the connecting position between the fourth dust box sidewall 1614 and the fifth dust box sidewall 1615.
In the above embodiment, the air inlet 163 is formed on the second dust box sidewall 1612, and the dust exhaust port 164 is formed on the fourth dust box sidewall 1614, such that the flowing of the dust collection airflow is smooth. The dust inlet 166 is formed on the first dust box sidewall 1611, and the air vent port 1601 is formed on the third dust box sidewall 1613, such that the flowing of the dust suction airflow is smooth.
As shown in Fig. 6, one end of the flow guide member 165 is adjacent to one side of the dust exhaust port 164, and is arranged at an angle of 90 degrees to the plane where the dust exhaust port 164 is located, such that the dust collection airflow is exhausted from the dust exhaust port 164 at an approximately vertical angle under the guidance of the flow guide member 165.
As shown in Fig. 3, in some possible embodiments according to the present disclosure, the dust exhaust port 164 and the dust outlet 169 are communicated in the machine main body 110 of the self-moving cleaning device 100 through a dust exhaust channel 168, wherein the dust exhaust channel 168 is arranged at an angle of 90 degrees to the plane where the dust exhaust port 164 is located. That is, an extending direction of the flow guide member 165 is approximately parallel to an extending direction of the dust exhaust channel 168. Thus, the dust collection airflow in the dust box 160 can smoothly flow into the dust exhaust channel 168 under the guidance of the flow guide member 165, which further reduces the situation that the debris in the dust box 160 is gathered or blocked at the connecting position between the dust exhaust port 164 and the dust exhaust channel 168. Therefore, it is beneficial for improving the thoroughness of collecting the debris in the dust box 160 to the base station 200 and improving the dust collection effect.
As shown in Fig. 7 and Fig. 8, the base station 200 according to the present disclosure further includes a base station housing 210, and the base station housing 210 is provided with the dust collection port 2115. When the self-moving cleaning device 100 is docked at the base station 200, the dust outlet 169 of the self-moving cleaning device 100 is butted with the dust collection port 2115 on the base station 200 for the dust collection operation. Specifically, the base station 200 is provided with an accommodating cavity 211. When the self-moving cleaning device 100 is docked at the base station 200, at least part of the self-moving cleaning device 100 is accommodated in the accommodating cavity 211, and the dust collection port 2115 is located inside the accommodating cavity 211. Specifically, the dust collection port 2115 may be located on the sidewall of the accommodating cavity 211.
As shown in Fig. 9, Fig. 10 and Fig. 12, the dust collection assembly 260 of the base station 200 includes a dust collection apparatus 261, and a dust bag compartment 215, a noise reduction housing 262, a dust collection duct 263 and a dust collection fan 264 which are arranged in the base station housing 210. The dust collection apparatus 261 is arranged in the dust bag compartment 215, and the noise reduction housing 262 is provided with an air exhaust port 2621. The dust collection duct 263 is communicated with the dust collection port 2115, the dust bag compartment 215 and the noise reduction housing 262 to form a dust collection air duct, and the dust collection fan 264 is arranged on the dust collection air duct. A dust collection airflow generated by the dust collection fan 264 sucks the debris in the dust box 160 of the self-moving cleaning device 100 through the dust collection port 2115, and after the debris is collected and intercepted by the dust collection apparatus 261, the dust collection airflow is exhausted from the air exhaust port 2621. Since the airflow generated by operation of the dust collection fan 264 will be exhausted through the air exhaust port 2621 on the noise reduction housing 262, the noise reduction housing 262 can perform noise reduction on the airflow flowing therethrough. Therefore, the airflow in the dust collection air duct will be exhausted after being noise-reduced by the noise reduction housing 262, thereby greatly reducing an aerodynamic noise of the dust collection fan 264, reducing working noise of the fan and improving a comfort level of the user. The dust collection apparatus 261 may be a dust bag or other components that meet the requirements.
Specifically, in the dust collection assembly 260 of the base station 200 according to the embodiment of the present disclosure, as shown in Fig. 9, the dust collection duct 263 includes a first dust collection duct 2631 and a second dust collection duct 2632. The first dust collection duct 2631 communicates the dust collection port 2115 to the dust bag compartment 215, and the second dust collection duct 2632 communicates the dust collection fan 264 to the noise reduction housing 262. Under the condition that the dust outlet 169 of the self-moving cleaning device 100 is butted with the dust collection port 2115 of the base station 200, the dust collection airflow generated by the dust collection fan 264 flows this path: it is drawn from the dust box 160 of the self-moving cleaning device 100, passes through the dust exhaust channel 168 and the dust outlet 169, and flows into the dust bag 216 in the dust bag compartment 215 through the first dust collection duct 2631. After the debris is collected and intercepted by the dust collection apparatus 261, the dust collection airflow flows from the dust bag compartment 215 into the noise reduction housing 262 through the dust collection fan 264 and the second dust collection duct 2162, and is exhausted into the base station housing 210 through the air exhaust port 2621 of the noise reduction housing 262. The noise reduction housing 262 is used for performing noise reduction on the airflow flowing therethrough to achieve the purpose of reducing the working noise of the dust collection fan 264 and improve the comfort level of the user.
As shown in Fig. 13 and Fig. 14, an opening of the dust bag compartment 215 on the base station housing 210 is forward, and the front of the base station 200 is as shown in Fig. 7. As shown in Fig. 7 and Fig. 8, the base station 200 also includes a dust bag compartment cover 2156, and the dust bag compartment cover 2156 and the base station housing 210 are detachably connected through a snap-fit assembly to open or shield the opening of the dust bag compartment 215. It can be understood that when the dust bag compartment cover 2156 shields the opening of the dust bag compartment 215, the opening of the dust bag compartment 215 can also be sealed, such that the dust bag compartment 215 is a closed cavity to ensure that the dust collection air duct can generate negative pressure, ensuring that the dust collection operation can be reliably performed. When the dust bag compartment cover 2156 opens the opening of the dust bag compartment 215, it is convenient to replace the dust collection apparatus 261 in the dust bag compartment 215. As shown in Fig. 13, Fig. 14, Fig. 15 and Fig. 17, the base station 200 further includes a dust bag bracket 270 arranged in the dust bag compartment 215, and the dust collection apparatus 261 is mounted in the dust bag compartment 215 through the dust bag bracket 270.
In some possible embodiments according to the present disclosure, a first sound absorbing member is arranged in the noise reduction housing 262, and the first sound absorbing member may be a component made of sound absorbing cotton or other sound absorbing materials. By arranging the first sound absorbing member in the noise reduction housing 262, the dust collection airflow flowing through the noise reduction housing 262 can be subjected to noise reduction, further improving the noise reduction performance of the noise reduction housing 262.
In some possible embodiments according to the present disclosure, as shown in Fig. 12, the base station housing 210 is also provided with an air outlet 2119, and the air exhaust port 2621 is not opposite to the air outlet 2119. In other words, after being exhausted from the air exhaust port 2621 of the noise reduction housing 262, the dust collection airflow will flow into the base station housing 210 and be exhausted to the external environment through the air outlet 2119 formed in the base station housing 210. The air exhaust port 2621 is not opposite to the air outlet 2119, such that a propagation channel of the dust collection airflow between the air exhaust port 2621 and the air outlet 2119 is a bent channel, that is, the working noise of the dust collection fan 264 needs to be exhausted from the air outlet through the bent propagation channel between the air exhaust port 2621 and the air outlet 2119. Since the bent propagation channel plays a role of blocking the sound from propagation outward and can enhance the friction and dissipation of sound waves, the purpose of noise reduction is once again achieved when the dust collection airflow is exhausted to the external environment through the air exhaust port 2621 and the air outlet 2119, which reduces the influence of the noise on the user and is beneficial for improving the use comfort level of the user.
In the above embodiment, as shown in Fig. 12, the base station housing 210 includes four body sidewalls connected in sequence to define a frame structure. Further, the accommodating cavity 211 for accommodating the self-moving cleaning device 100 on the base station 200 may be located on one of the four body sidewalls located in the front of the base station 200, and the front of the base station 200 may be as shown in Fig. 7. The air exhaust port 2621 is opposite to one of the body sidewalls, and the air outlet 2119 may be formed on other body sidewalls. Thus, it can be ensured that the propagation channel for the dust collection airflow between the air exhaust port 2621 and the air outlet 2119 is a bent channel, thereby ensuring a better noise reduction effect.
The air outlet 2119 may be formed on one, two or three of other three body sidewalls except the body sidewall opposite to the air exhaust port 2621. In some embodiments, the air outlet 2119 may also be formed on the body sidewall opposite to the air exhaust port 2621 as long as the air outlet 2119 is not opposite to the air exhaust port 2621, for example, the air outlet 2119 is arranged away from the air exhaust port 2621.
As shown in Fig. 11, in some possible embodiments according to the present disclosure, the dust collection fan 264 is provided with a second sound absorbing member 2641. The second sound absorbing member 2641 is used for performing sound absorption on the airflow flowing through an air outlet port of the dust collection fan 264, thereby further reducing the aerodynamic noise of the dust collection fan 264, reducing the working noise of the dust collection fan 264 and improving the comfort level of the user.
Further, the second sound absorbing member 2641 is also configured to filter the airflow flowing through the air outlet port of the dust collection fan 264. For example, the second sound absorbing member 2641 may be sound absorbing filter cotton, such that the second sound absorbing member 2641 further has the function of filtering. That is, the second sound absorbing member 2641 plays a role of not only reducing the noise and but also re-filtering the dust collection airflow, and can filter the airflow flowing out of the air outlet port of the dust collection fan 264 while greatly reducing the working noise of the dust collection fan 264. Thus, the cleanliness of the airflow exhausted to the external environment can be improved.
Further, impurities such as carbon powder will be generated during working of the dust collection fan 264, and these impurities may also be filtered by the second sound absorbing member 2641. In other words, the second sound absorbing member 2641 can not only filter the dust collection airflow from the dust box 160, but also filter the impurities such as carbon powder generated by the dust collection fan 264 in work, which further improves the cleanliness of the airflow exhausted to the external environment and reduces environmental pollution.
As shown in Fig. 10 and Fig. 11, in the above embodiment, the dust collection fan 264 is a vortex fan. The vortex fan is compact in size, high in pressure and fast in wind speed, can meet the design requirement of the base station 200 for a small size, and in addition, can ensure higher dust collection efficiency and better dust collection effect.
The vortex fan is provided with a vortex cavity 2642 and a transition cavity 2643 which are communicated through an air passing port 2644; an air inlet port is formed on the cavity wall of the vortex cavity 2642; the air outlet port is formed on the cavity wall of the transition cavity 2643; and the second sound absorbing member 2641 is located in the vortex cavity 2642. Thus, the second sound absorbing member 2641 can be utilized to perform sound absorption and filtering operations on the dust collection airflow flowing from the vortex cavity 2642 to the transition cavity 2643.
As shown in Fig. 9, Fig. 13 and Fig. 14, in some possible embodiments according to the present disclosure, the dust bag compartment 215 is provided with an airflow inlet 2151 and an airflow outlet 2152, the dust collection apparatus 261 is communicated with the airflow inlet 2151, the air inlet port of the dust collection fan 264 is connected to the airflow outlet 2152, and the air vent port of the dust collection fan 264 is connected to the noise reduction housing 262 through the second dust collection duct 2632. In other words, the dust collection fan 264 is located between the dust bag compartment 215 and the noise reduction housing 262, and is communicated with the noise reduction housing 262 through the second dust collection duct 2632. It should be noted that the airflow inlet 2151 of the dust bag compartment 215 is communicated with the dust collection port 2115 of the base station through the first dust collection duct 2631, and the dust box 160 of the self-moving cleaning device 100 is also provided with an air inlet 163 and a dust inlet 166. After the dust outlet 169 of the self-moving cleaning device 100 is butted with the dust collection port 2115 of the base station 200, due to the dust collection airflow generated by the dust collection fan 264 in work, the debris in the dust box 160 of the self-moving cleaning device 100 can flow along with the dust collection airflow, and flow through the dust collection apparatus 261 from the dust outlet 169 of the self-moving cleaning device 100, the dust collection port 2115 on the base station 200, the first dust collection duct 2631 and the airflow inlet 2151 of the dust bag compartment 215. After the debris is collected and intercepted by the dust collection apparatus 261, the dust collection airflow flows into the dust collection fan 264 through the airflow outlet 2152 of the dust bag compartment 215, then flows into the noise reduction housing 262 from the air outlet port of the dust collection fan 264 through the second dust collection duct 2632, is exhausted to the interior of the base station housing 210 through the air exhaust port 2621 of the noise reduction housing 262, and is exhausted to the external environment through the air outlet 2119 on the base station housing 219 to achieve the entire circulation.
The circumferential side of the dust collection port 2115 of the base station 200 is also provided with a sealing part. After the dust outlet 169 of the self-moving cleaning device 100 is butted with the dust collection port 2115, the gap between the dust outlet 169 and the dust collection port 2115 can be sealed by the sealing part, which can avoid the problem of failure of dust collection caused by no negative pressure formed in the dust collection air duct arising from air leakage between the dust outlet 169 and the dust collection port 2115, and in addition, can avoid the debris leakage caused by the air leakage between the dust outlet 169 and the dust collection port 2115. Thus, it is ensured that the dust collection operation can be performed smoothly, which is beneficial for ensuring the better dust collection effect. Specifically, the sealing part may be an elastic member.
It can be understood that, as shown in Fig. 8, the interior of the accommodating cavity 211 of the base station 200 is also provided with a decorative port 21151. For example, the decorative port 21151 is formed on the sidewall of the accommodating cavity 211. The decorative port 21151 and the dust collection port 2115 are distributed on both sides of the center line of the base station 200 parallel to the vertical direction. For example, the decorative port 21151 and the dust collection port 2115 are distributed on the left and right sides of the accommodating cavity 211. An elastic part may also be arranged on the circumferential side of the decorative port 21151. In this way, when the self-moving cleaning device 100 is docked on the base station 200 and after the dust outlet 169 is butted with the dust collection port 2115, other parts of the self-moving cleaning device 100 will be abutted against the elastic part on the circumferential side of the decorative port 21151, thereby ensuring that the self-moving cleaning device 100 is reliably docked on the base station 200, and avoiding the possibility of shaking of the self-moving cleaning device 100 in the dust collection process. In addition, the provided decorative port 21151 can ensure the cleanliness and aesthetics of the appearance of the base station 200.
As shown in Fig. 13, in the above embodiment, a first filter member 2153 is arranged in the dust bag compartment 215, and the first filter member 2153 is located at the airflow outlet 2152. The provided first filter member 2153 can filter the dust collection airflow flowing into the dust collection fan 264 from the airflow outlet 2152 of the dust bag compartment 215, such that the cleanliness of the airflow flowing into the dust collection fan 264 can be improved, thereby being beneficial for improving the service life of the dust collection fan 264 and improving the reliability of the dust collection assembly 260.
Specifically, the first filter member 2153 may be a filter screen, filter cotton or other filter components, and the first filter member 2153 may be fixed at the airflow outlet 2152 of the dust bag compartment 215 through at least one of a snap-fit structure, a mortise-and-tenon structure, an adhesive and a screw structure.
As shown in Fig. 3, the machine main body 110 of the self-moving cleaning device 100 is provided with the dust outlet 169, and the dust exhaust channel 168 for communicating the dust box 160 to the dust outlet 169 is arranged inside the machine main body 110. As shown in Fig. 7 and Fig. 8, the base station 200 according to the present disclosure includes the base station housing 210 and the dust collection assembly 260. The base station housing 210 is provided with the dust collection port 2115, and the dust collection assembly 260 is communicated with the dust collection port 2115. When the self-moving cleaning device 100 is docked at the base station 200, and after the dust outlet 169 of the self-moving cleaning device 100 is butted with the dust collection port 2115 on the base station 200, the dust collection assembly 260 on the base station 200 works, and the airflow flows through the dust box 160 and the dust exhaust channel 168, and flows into the base station 200 through the dust outlet 169 and the dust collection port 2115 which are butted. Thus, debris in the dust box 160 can be collected in the base station 200, thereby achieving the dust collection operation. Specifically, the base station 200 is provided with the accommodating cavity 211. When the self-moving cleaning device 100 is docked on the base station 200, at least part of the self-moving cleaning device 100 is accommodated in the accommodating cavity 211, and the dust collection port 2115 is located in the accommodating cavity 211. Specifically, the dust collection port 2115 may be located on the sidewall of the accommodating cavity 211.
As shown in Fig. 13, Fig. 14, Fig. 15 and Fig. 17, in some possible embodiments according to the present disclosure, the base station 200 further includes the dust bag bracket 270 arranged in the dust bag compartment 215. The dust bag bracket 270 is configured to mount the dust collection apparatus 261, the dust bag bracket 270 is provided with a guide groove 271, and the guide groove 271 is configured to guide the dust collection apparatus 261 to be connected to or separated from the dust bag bracket 270. In other words, the dust collection apparatus 261 and the dust bag bracket 270 can be quickly and conveniently assembled and disassembled through the guidance of the guide groove 271 on the dust bag bracket 270, which further facilitates the disposal of the debris collected by the base station 200. The operation is convenient.
By arranging a jamming-and-pinch-prevention structure 2711 on the groove wall of the guide groove 271, occurrences where the dust collection apparatus 261 is jammed or pinched in the guide groove 271 can be reduced. With the provided jamming-and-pinch-prevention structure 2711, the dust collection apparatus 261 can be unfolded smoothly and completely. The dust collection apparatus 261 has a larger size and the problem that the dust collection apparatus 261 is jammed in the guide groove 271 and affects the flowing of the dust collection airflow is avoided, such that the dust collection effect of the base station 200 is improved. It should be noted that the dust collection apparatus 261 includes a dust bag body, the dust bag body is made of an air-permeable yet fine-particle-filtering material, such as a non-woven fabric and a paper material, and the dust bag body is configured to accommodate the debris. As mentioned in the present disclosure, the scenario where the dust collection apparatus 261 is jammed on the groove wall of the guide groove 271 means that the dust bag body is jammed on the sidewall of the guide groove 271.
As shown in Fig. 18 and Fig. 19, the opening of the dust bag compartment 215 is located in the front of the base station 200, and the front of the base station is as shown in Fig. 7. In other words, the dust bag compartment 215 is arranged in the front of the base station 200, and an opening of the guide groove 271 is consistent with the opening of the dust bag compartment 215 in direction. Thus, by the opening of the dust bag compartment 215, the dust collection apparatus 261 can be mounted on the dust bag bracket through the guide groove 271 or disassembled from the dust bag bracket 270 through the guide groove 271. If the opening of the dust bag compartment 215 faces the front of the base station 200, then the opening of the guide groove 271 also faces the front of the base station 200. Thus, the user can smoothly mount the dust collection apparatus 261 on the dust bag bracket 270 or disassemble the dust collection apparatus 261 from the dust bag bracket 270 through the guide groove 271 from the front of the base station 200, and the user does not need to reorient his hand within the dust bag compartment 215, which conforms to ergonomic principles and is convenient for operation.
In the above embodiment, as shown in Fig. 5, Fig. 7, Fig. 18 and Fig. 19, the base station 200 further includes the dust bag compartment cover 2156, the dust bag compartment 215 is arranged in the front of the base station housing 210, and the dust bag compartment cover 2156 is detachably connected to the base station housing 210 to shield the dust bag compartment 215 or open the opening of the dust bag compartment 215. Specifically, the dust bag compartment cover 2156 and the base station housing 210 are assembled and disassembled through the snap-fit assembly to open the opening of the dust bag compartment 215 to assemble and disassemble the dust collection apparatus 261. Due to the simple structure and lower cost of the snap-fit assembly, compared with the base station 200 provided with a sliding drawer apparatus to place the dust collection apparatus 261 in the related art, the structure of the base station 200 is simplified, which is beneficial for reducing the manufacturing cost of the base station 200. In addition, compared with the dust bag compartment cover 2161 and the base station housing 210 which are connected by a magnetic attraction assembly in the related art, the advantages of lower cost and suitability for popularization and application are also achieved.
As shown in Fig. 18, in some possible embodiments according to the present disclosure, the guide groove 271 is obliquely arranged relative to the vertical direction, such as the direction from the top to the bottom of the base station 200. For example, the length direction of the guide groove 271 is obliquely arranged relative to the vertical direction, wherein the length direction of the guide groove 271 is as shown by the arrow L in Fig. 18. Thus, after the dust collection apparatus 261 is mounted on the dust bag bracket 270, the dust bag body of the dust collection apparatus 261 will hang down under the action of gravity. Further, the dust bag bracket 270 may be located at the top of the dust bag compartment 215, wherein the top of the dust bag compartment 215 is as shown by the arrow in Fig. 18. For example, the dust bag bracket 270 is located at one corner of the top of the dust bag compartment 215.
Since the dust bag body is made of a soft material, the dust bag body will hang down under the action of gravity in the process that the dust collection apparatus 261 is mounted on the dust bag bracket 270. As a result, the situation that the dust bag body is pinched by the lower groove wall of the guide groove 271 will occur, which will hinder the full unfolding of the dust bag body in the subsequent dust collection process. It should be noted that after the dust bag 216 is mounted on the dust bag bracket 270, the dust bag body will be unfolded under the action of the dust collection airflow when the dust collection fan 264 works. In addition, under normal circumstances, the dust collection apparatus 261 is inserted and mounted through the front end opening of the guide groove 271, and the front end of the guide groove 271 may be understood as one surface of the guide groove 271 opposite to the opening of the dust bag compartment 215. For this, a notch structure is arranged on the front end surface of the lower groove wall of the guide groove 271, that is, the notch structure is opposite to the opening of the dust bag compartment 215 and is arranged on the lower groove wall of the guide groove 271. By using the notch structure to avoid the dust bag body, the situation that part of the dust bag body is jammed in the guide groove 271 under the action of gravity can be avoided, which is beneficial for smooth and complete unfolding of the dust bag body in the subsequent dust collection process.
The notch structure may be a triangular notch, an arc-shaped notch, or a notch with other shapes that meet the requirements. Further, the edge of the notch structure may be provided with a transition surface to play a guiding role. For example, the transition surface may be a smooth curved surface or inclined surface to ensure that the dust bag body can descend smoothly under the action of gravity without being jammed on the groove wall of the guide groove 271.
As shown in Fig. 16 and Fig. 17, in some possible embodiments according to the present disclosure, a hollow cavity body is arranged inside the dust bag bracket 270. The hollow cavity body includes a dust exhaust connecting port 2712 located on the bracket sidewall of the dust bag bracket 270 facing the inside of the dust bag compartment 215, and the dust exhaust connecting port 2712 is configured to be butted with an inlet of the dust collection apparatus 261. The hollow cavity body further includes a dust intake connecting port 2713 located on the bracket sidewall of the dust bag bracket 270 facing the outside of the dust bag compartment 215. As shown in Fig. 14, the dust bag compartment 215 is provided with the airflow inlet 2151, and the dust intake connecting port 2713 is configured to be butted with the airflow inlet 2151 of the dust bag compartment 215.
In other words, the hollow cavity body of the dust bag bracket 270 may be used as part of the dust collection air duct of the base station 200. When the dust collection assembly 260 of the base station 200 works, the dust collection airflow flows into the base station 200 through the dust box 160 of the self-moving cleaning device 100, and then flows into the dust collection apparatus 261 through the airflow inlet 2151 of the dust bag compartment 215 and the hollow cavity body of the dust bag bracket 270, so as to collect and intercept the debris in the dust collection apparatus 261.
As shown in Fig. 17, the notch structure is located at the connecting position between the groove wall and the dust exhaust connecting port 2712. Under normal circumstances, the dust bag body will be jammed at the connecting position between the groove wall of the guide groove 271 and the dust exhaust connecting port 2712. Therefore, by arranging the notch structure at this position, the situation of jamming of the dust bag body can be reduced. However, under normal circumstances, the dust bag body will be jammed at the part of the bottom end of the dust exhaust connecting port 2712 when hanging down under the action of gravity. Thus, by distributing the notch structure at least at the bottom of the front end of the dust exhaust connecting port 2712, the occurrence of jamming of the dust bag body can be greatly reduced.
Specifically, one notch structure may be arranged at the connecting position between the front end bottom of the dust exhaust connecting port 2712 and the lower groove wall of the guide groove 271. Or, as shown in Fig. 18, one notch structure may be arranged at the connecting position between the front end bottom of the dust exhaust connecting port 2712 and the lower groove wall of the guide groove 271, and at the connecting position between the front end top and the lower groove wall of the guide groove 271, respectively. The top-bottom direction in Fig. 18 is the top-bottom direction of the base station.
As shown in Fig. 14 and Fig. 16, in the above embodiment, the base station 200 further includes a sealing member 273, which is arranged between the bag chamber sidewall 21551 of the dust bag compartment 215 and the bracket sidewall where the dust intake connecting port 2713 is located. The sealing member 273 is used for sealing the gap between the bag chamber sidewall 21551 and the bracket sidewall. Thus, the sealing property of the connection between the bag chamber sidewall 21551 of the dust bag compartment 215 and the bracket sidewall of the dust bag bracket 270 can be improved, the problem of failure of dust collection caused by no negative pressure formed in the dust collection air duct arising from air leakage between the bag chamber sidewall 21551 and the bracket sidewall of the dust bag bracket 270 can be avoided. In addition, the problem of debris leakage from the gap between the bag chamber sidewall 21551 and the bracket sidewall can be avoided, which further ensures that the dust collection operation can be smoothly performed and is beneficial for ensuring the better dust collection effect.
The sealing member 273 may be sealing cotton, a sealing ring, a sealing strip or other sealing structures. Specifically, the sealing member 273 may be sealing foam, the sealing member 273 may be fixed on the bracket sidewall by means of bolts and/or positioning posts, and then the dust bag bracket 270 is connected to the bag chamber sidewall 21551 to seal the gap between the bracket sidewall and the bag chamber sidewall 21551 by the sealing member 273.
As shown in Fig. 17, in some possible embodiments according to the present disclosure, the dust bag bracket 270 includes a sliding baffle 272 that can slide along the guide groove 271, and the sliding baffle 272 is configured to switch between a first position and a second position. In response to the sliding baffle 272 being in the first position, the sliding baffle 272 shields the dust exhaust connecting port 2712, and in response to the sliding baffle 272 being in the second position, the sliding baffle 272 exposes the dust exhaust connecting port 2712. Since the dust collection apparatus 261 is a consumable, it can be detachably mounted with the dust bag bracket 270. When the dust bag bracket 270 in the above design is not equipped with the dust collection apparatus 261, the dust exhaust connecting port 2712 can be shielded by the sliding baffle 272 to isolate the dust bag compartment 215 from the dust collection air duct. Therefore, the suction force generated by the dust collection fan 264 cannot enter the dust bag compartment 215, and the debris is prevented from entering the dust bag compartment 215 not equipped with the dust collection apparatus 261. It should be noted that, as shown in Fig. 16, the dust bag bracket 270 further includes an elastic part 274 connected to the sliding baffle 272, and the elastic part 274 is configured such that the sliding baffle 272 tends to be in the first position. When the sliding baffle 272 is not subjected to an external force, the sliding baffle 272 is in the first position under the action of the elastic part 274, such that the sliding baffle 272 shields the dust exhaust connecting port 2712.
It can be understood that the dust bag 216 is configured to slide along an extending direction of the guide groove 271. When the dust collection apparatus 261 is inserted into the guide groove 271 and slides along the guide groove 271 to the interior of the dust bag compartment 251, the sliding baffle 272 will be pushed to slide along the extending direction of the guide groove 271, such that the dust collection apparatus 261 is mounted on the dust bag bracket 270, and the sliding baffle 272 exposes the dust exhaust connecting port 2712 to enable the opening of the dust bag 216 to be butted with the dust exhaust connecting port 2712. After the dust bag 216 is mounted on the dust bag bracket 270, the dust bag may be pulled in the direction towards the outside of the dust bag compartment 215, such that the dust bag 216 can slide along the guide groove 271 and be disengaged from the guide groove 271 to achieve the disassembling of the dust bag 216 from the dust bag bracket 270. In addition, under the action of the elastic part 274, the sliding baffle 272 may be reset to its initial position to shield the dust exhaust connecting port 2712.
As shown in Fig. 17, in some possible embodiments according to the present disclosure, the lower groove wall of the guide groove 271 is provided with a hollowed-out structure at the position away from the jamming-and-pinch-prevention structure 2711. That is, the lower groove wall of the guide groove 271 is provided with a hollowed-out structure in the dust bag compartment 215 at the opening away from the dust bag compartment 215. The hollowed-out structure is configured to expose part of the sliding baffle 272, and may be an opening. The bracket bottom wall of the dust bag bracket 270 is provided with a guide structure 2714 located in the dust bag compartment 215, and the guide structure 2714 is located on one side of the hollowed-out structure away from the sliding baffle 272. The provided guide structure 2714 can prevent the dust collection apparatus 261 from misaligning, jamming or protruding through the hollowed-out structure in the guide groove 271 when the dust collection apparatus 261 is inserted into the guide groove 271, such that the dust collection apparatus 261 can be smoothly abutted against the sliding baffle 272 on the dust bag bracket 270 under the guidance of the guide groove 271 and the guide structure 2714, thereby pushing the sliding baffle 272 to slide in the guide groove 271 to expose the dust exhaust connecting port 2712.
The guide structure 2714 may be a guide protrusion, and one side of the guide protrusion facing the guide groove 271 is provided with a guide inclined surface. Under the guidance of the guide inclined surface, the dust collection apparatus 261 in the guide groove 271 can smoothly slide in the guide groove 271 and can be accurately abutted against the sliding baffle 272.
As shown in Fig. 13, the dust bag compartment 215 is provided with the airflow outlet 2152, wherein the airflow outlet 2152 is used for being connected to the dust collection fan 214. Typically, in order to improve the space utilization rate and the volume of the dust bag, the dust bag is usually set as large as or slightly smaller than the dust bag compartment in design and production. However, in this way, during dust collection, blockage will be caused since the bottom of the dust bag is possibly sucked onto the airflow outlet of the dust bag compartment due to the suction force from the dust collection fan. In long-term use, due to the gravity of dust and the suction force from the dust collection fan, the dust bag not in contact with the airflow outlet originally is possibly elongated. As a result, the bottom of the dust bag covers the airflow outlet to cause blockage. For this, in some possible embodiments according to the present disclosure, a plurality of supporting parts 2154 is arranged in the dust bag compartment 215, and spaced apart on the circumferential side of the airflow outlet 2152 for supporting at least part of the dust collection apparatus 261. With the provided supporting parts 2154, the dust collection apparatus 261 is incapable of completely covering the airflow outlet 2152, thereby facilitating the flowing of the dust collection airflow, preventing the occurrence of blockage, and being beneficial for improving the dust collection efficiency.

The motion mechanism is used for driving the cleaning element 183 to move. For example, the motion mechanism may drive the cleaning element 183 to perform operations, such as lifting and lowering of the cleaning element 183 and also the rotation of the cleaning element 183. Thus, the lifting and rotating operations of the cleaning element 183 can be achieved through the motion mechanism according to the demands as to whether the cleaning element 183 needs to be in contact with the surface to be cleaned, so as to meet different functional requirements of the cleaning element 183. That is, the implementation of differentiated strategies for the cleaning element 183 can be achieved. Therefore, the cleaning performance of the self-moving cleaning device, the cleaning efficiency and use experience are improved.
