Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, and more specifically to a cleaning system. Background Art

[0002] At present, when cleaning systems (including base stations and cleaning equipment, such as sweeping robots, etc.) collect dust, the solution usually adopted is that when the cleaning equipment enters the preset position on the base station, the dust in the dust box of the cleaning equipment is sucked into the dust collection chamber of the base station through the fan on the base station. In order to achieve better dust collection effect, the common solution on the market is to use a higher-power base station fan, but the dust collection effect does not increase linearly with the increase of fan power, and the cost is relatively high. Summary of the invention

[0003] A series of simplified concepts are introduced in the Summary of the Invention, which will be further described in detail in the Detailed Description of the Invention. The Summary of the Invention does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the scope of protection of the claimed technical solution.

[0004] The embodiments of the present application provide a cleaning system that can significantly improve the dust collection effect of a base station.

[0005] The present application provides a cleaning system, which includes:

[0006] A cleaning device, the cleaning device comprising a dust box and a first fan connected to the dust box, the first fan being used to generate negative pressure in the dust box to absorb garbage outside the dust box into the dust box;

[0007] A base station, the base station comprising a dust collecting chamber and a second fan connected to the dust collecting chamber,

[0008] The cleaning system has a dust collection mode. When the cleaning system is in the dust collection mode, the dust collection chamber is used to communicate with the dust box, and the second fan is configured to generate negative pressure in the dust collection chamber to absorb garbage in the dust box into the dust collection chamber; the first fan is configured to start after the second fan has worked for a preset time.

[0009] According to the cleaning system of the present invention, by controlling the first fan of the cleaning equipment to start after the second fan of the base station has worked for a preset time, the dust collection effect of the base station can be significantly improved through the joint action of the two fans without changing the power of the second fan, and the cost is relatively low.

[0024] Refer to the attached Figure 1-4 The cleaning system according to an embodiment of the present application is exemplarily described. The cleaning system includes a cleaning device 100 and a base station 200 .

[0025] The cleaning device 100 may be a sweeping robot, a sweeping and mopping robot, etc., which includes a dust box 110 and a first fan 120 connected to the dust box 110, and the first fan 120 is used to generate negative pressure in the dust box 110 to absorb garbage outside the cleaning device 100 into the dust box 110. Specifically, the dust box 110 includes a accommodating chamber 111, a dust inlet 112 connected to the accommodating chamber 111, an air outlet connected to the accommodating chamber 111, and a dust outlet 113 connected to the accommodating chamber 111. The accommodating chamber 111 is used to accommodate garbage. The dust inlet 112 is connected to the outside of the cleaning device 100, and the garbage outside the cleaning device 100 can enter the accommodating chamber 111 through the dust inlet 112. In the embodiment of the present application, the cleaning device 100 has a dust inlet channel 130, and the dust inlet 112 is connected to the outside of the cleaning device 100 through the dust inlet channel 130. In some other embodiments, the dust inlet channel 130 may not be provided on the cleaning device 100, and the dust inlet 112 of the dust box 110 is directly connected to the outside of the cleaning device 100. The air inlet of the first fan 120 is directly connected to the air outlet of the dust box 110 or through a connecting air duct. The first fan 120 is used to generate negative pressure in the accommodating chamber 111 of the dust box 110 to absorb the garbage outside the cleaning device 100 into the dust box 110. A filter is provided at the air outlet of the dust box 110 or upstream of the air outlet. The filter allows the gas in the accommodating chamber 111 to enter the first fan 120 through it, and restricts the garbage in the accommodating chamber 111 from entering the first fan 120 through it, so that the garbage remains in the accommodating chamber 111. The filter can be a filter, a high-efficiency air filter (HEPA) or other suitable filter. The dust outlet 113 of the dust box 110 is used to allow the garbage in the accommodating chamber 111 to leave the accommodating chamber 111. A cover plate is provided at the dust outlet 113, and the cover plate is located outside the dust outlet 113. The cover plate can be connected to the dust box 110 through a torsion spring, or the cover plate can be a rubber sheet directly connected to the dust box 110. When the air pressure in the accommodating chamber 111 is less than or equal to the air pressure outside the dust outlet 113, the cover plate covers the dust outlet 113, so that the dust outlet 113 is closed; when the air pressure in the accommodating chamber 111 is greater than the air pressure outside the dust outlet 113 and the force exerted by the air pressure on the cover plate exceeds a certain magnitude, the air pressure pushes the cover plate to move and open the dust outlet 113. At this time, the garbage in the accommodating chamber 111 can leave the accommodating chamber 111 through the dust outlet 113. Thus, when the first fan 120 is working to collect dust, negative pressure is generated in the accommodating chamber 111, the cover plate closes the dust outlet 113, and the gas outside the cleaning device 100 together with the garbage enters the accommodating chamber 111 through the dust inlet channel 130 and the dust inlet 112 in sequence, and then the gas enters the first fan 120 through the filter element and the air outlet, and is discharged through the air outlet of the first fan 120, and the garbage remains in the accommodating chamber 111.

[0026] See attached Figure 3In the embodiment of the present application, the cleaning device 100 also includes a device body 101 and a walking mechanism 160, the dust box 110 and the first fan 120 are both installed on the device body 101, and the walking mechanism 160 includes a power member connected to the device body 101 and a walking wheel 161 connected to the power member, and the power member is used to drive the walking wheel 161 to rotate relative to the device body 101 to drive the device body 101 to move on the surface to be cleaned. In the embodiment of the present application, the power member is a motor, and the walking mechanism 160 also includes a universal wheel 162 rotatably connected to the device body 101, and the universal wheel 162 is located at the front of the device body 101 facing the side of the surface to be cleaned. It should be noted that the "front" in this application refers to the part facing the forward direction of the cleaning device 100 (the side facing the forward direction of the cleaning device 100). There can be two walking wheels 161, which are located in the middle of the side of the device body 101 facing the surface to be cleaned. The walking wheel 161 and the universal wheel 162 can be arranged in an isosceles triangle on the side of the device body 101 facing the surface to be cleaned. In some embodiments, the driving assembly may include a power member and a track wheel. The track wheel is located on the side of the equipment body 101 facing the surface to be cleaned. The power member is connected to the track wheel for driving the track wheel to rotate, thereby driving the equipment body 101 to move on the surface to be cleaned.

[0027] In the embodiment of the present application, the cleaning device 100 further includes a roller brush 140 and a roller brush motor for driving the roller brush 140 to rotate, and the roller brush 140 is used to clean the surface to be cleaned while rotating. The roller brush 140 is located on the side of the device body 101 facing the surface to be cleaned and on the outside of the dust inlet 112 of the dust box 110. The device body 101 has a mounting groove for mounting the roller brush 140 facing the surface to be cleaned, and the roller brush 140 is mounted in the mounting groove. The mounting groove also has a roller brush cover 170 on the outside, and the roller brush cover 170 is detachably connected to the device body 101. The roller brush cover 170 has a hollow portion at a position corresponding to the mounting groove, and the hollow portion is used to expose the roller brush 140. Specifically, the roller brush 140 is located on a side of the dust inlet channel 130 away from the dust inlet port 112, and the central axis of the roller brush 140 is parallel to the surface to be cleaned. The bristles and / or rubber strips on the roller brush 140 are in contact with the surface to be cleaned, so that when the roller brush 140 rotates, the bristles and / or rubber strips can push the garbage on the surface to be cleaned toward the dust inlet channel 130, so that it can enter the accommodating chamber 111 through the dust inlet channel 130 and the dust inlet port 112. The roller brush motor is transmission-connected to the roller brush 140 of the roller brush 140, and is used to drive the roller brush 140 to rotate. In an embodiment of the present application, the roller brush motor can drive the roller brush 140 to rotate in a first direction and a second direction, and the first direction is consistent with the rotation direction of the walking wheel 161 when the cleaning device 100 moves forward, that is, the first direction is Figure 1 The second direction is opposite to the first direction, that is, the second direction is Figure 1When the cleaning device 100 moves on the surface to be cleaned and the first fan 120 works to collect dust, the roller brush motor drives the roller brush 140 to rotate in the first direction to push the garbage on the surface to be cleaned to the dust inlet channel 130 and then absorb it into the accommodating cavity 111 of the dust box 110.

[0028] The base station 200 includes a dust collecting chamber 210 and a second fan 220. The dust collecting chamber 210 is used to hold garbage. When the cleaning device 100 is in a preset position in the base station 200, the dust collecting chamber 210 is connected to the dust box 110 through the dust collecting channel 300. In an embodiment of the present application, the dust collecting channel 300 includes a first channel 150 located on the cleaning device 100 and a second channel 230 located on the base station 200, the first end of the first channel 150 is connected to the dust box 110, the cover plate outside the dust outlet 113 is located in the first channel 150, and the second end of the first channel 150 is the first docking port 151 on the cleaning device 100. The first end of the second channel 230 is connected to the dust inlet 112 of the dust collecting chamber 210, and the second end of the second channel 230 is the second docking port on the base station 200. When the cleaning device 100 is in a preset position in the base station 200, the first docking port 151 docks with the second docking port (i.e. docks by abutting or plugging), so that the dust collecting chamber 210 is connected to the dust box 110 through the dust collecting channel 300. The second fan 220 is used to generate negative pressure in the dust collecting chamber 210 to absorb the garbage in the dust box 110 into the dust collecting chamber 210 through the dust collecting channel 300. The air inlet of the second fan 220 is connected to the air outlet of the dust collecting chamber 210, and a filter is provided at the air outlet, which allows the gas in the accommodating chamber 111 to enter the fan through it, and restricts the garbage in the accommodating chamber 111 from entering the fan through it, so that the garbage remains in the accommodating chamber 111. The filter can be a filter, a high-efficiency air filter or other suitable filter. Thus, when the cleaning device 100 is in a preset position in the base station 200 and the second fan 220 is working, the second fan 220 generates negative pressure in the dust collecting chamber 210, and the gas pressure in the dust collecting channel 300 is less than the pressure in the accommodating chamber 111 of the dust box 110. The cover is opened, and the garbage in the accommodating chamber 111 enters the dust collecting chamber 210 through the dust outlet 113, the dust collecting channel 300, and the dust inlet 112 of the dust collecting chamber 210 in turn, so that the garbage in the dust box 110 can be absorbed and stored in the dust collecting chamber 210.

[0029] In an embodiment of the present application, the first docking port 151 is located at the rear of the cleaning device 100 to achieve dust collection at the rear. The dust inlet 112 of the dust box 110 is located on the side of the dust box 110 facing the front of the cleaning device, and the dust outlet 113 of the dust box is located on the side of the dust box 110 facing the rear of the cleaning device, and the dust outlet 113 is connected to the first docking port 151. Thus, when the second fan 220 is working to collect dust, the flow trajectory of the airflow in the dust box 110 is a straight line (or approximately a straight line), which can better take away the garbage in the dust box 110, and there is basically no dead angle. In some other embodiments, the first docking port can be located at the bottom of the cleaning device 100 to achieve bottom dust collection, and the position of the first docking port can be flexibly configured according to the specific design requirements of the cleaning device 100 and the base station 200 by the technical personnel in the art.

[0030] In the embodiment of the present application, the cleaning system has a dust collection mode. When the cleaning system is in the dust collection mode, the dust collection chamber 210 is connected to the dust box 110, and the second fan 220 is first started to generate negative pressure in the dust collection chamber 210 to absorb the garbage in the dust box 110 into the dust collection chamber 210. The first fan 120 is started after the second fan 220 has worked for a preset time, and the preset time can be 5 seconds or other time greater than 5 seconds, such as 10 seconds. When the cleaning system enters the dust collection mode, the second fan 220 is started to start working. After the second fan 220 is started, the airflow enters the dust collection chamber 210 from the outside of the cleaning device 100 through the dust inlet channel 130, the dust inlet port 112, the accommodating chamber 111, the dust outlet port 113, and the dust collection channel 300 in sequence (the direction of the airflow is as shown in FIG. 1 ). Figure 1 As shown in A). Since the first fan 120 is not working at this time, the airflow preferentially carries away the fine dust and some garbage in the accommodating chamber 111 of the dust box 110 and enters the dust collecting chamber 210, which can effectively prevent the dust from adhering to the filter element in the dust box 110, thereby increasing the service life of the filter element. After the second fan 220 has been working for a preset time, the first fan 120 starts to work. At this time, the first fan 120 and the second fan 220 work at the same time, and a part of the airflow that enters the accommodating chamber 111 through the dust inlet channel 130 and the dust inlet port 112 enters the dust collecting chamber 210 through the dust outlet port 113 and the dust collecting channel 300 (the direction of the airflow is shown in FIG. 1 ). Figure 2 A in the figure), another part of the airflow enters the first fan 120 through the air outlet on the dust box 110, and is discharged through the air outlet of the first fan 120 (the direction of the airflow is shown in FIG. Figure 2B). The simultaneous operation of the first fan 120 and the second fan 220 can significantly increase the velocity and flow rate of the airflow in the dust box 110, thereby being able to carry heavier garbage, so that it can enter the dust collecting chamber 210 through the dust outlet 113 and the dust collecting channel 300 under the action of the second fan 220, thereby improving the dust collection effect of the base station 200. In the embodiment of the present application, the power of the second fan 220 is greater than the power of the first fan 120, thereby preventing some garbage from being adsorbed on the filter element of the dust box 110 and unable to enter the dust collecting chamber 210.

[0031] In an embodiment of the present application, the cleaning system may enter the dust collection mode when a specific button corresponding to the dust collection mode on the base station 200 is triggered. In some other embodiments, the cleaning system may automatically enter the dust collection mode when other preset trigger conditions are met. For example, the base station 200 and / or the cleaning device may be provided with an in-place determination unit, and the in-place determination unit is used to determine whether the cleaning device 100 is in a preset position in the base station 200. When the in-place determination unit determines that the cleaning device 100 is in the preset position in the base station 200, the cleaning system enters the dust collection mode. The in-place determination unit may include a contact sensor, a proximity sensor or other suitable sensor provided on the base station 200, which is used to be triggered when the cleaning device 100 is in the preset position in the base station 200, so that when it is triggered, it can be determined that the cleaning device 100 is in the preset position in the base station 200. Alternatively, when the charging electrode on the base station 200 is in electrical contact with the charging electrode on the cleaning device 100, it is determined that the cleaning device 100 is in a preset position in the base station 200. It should be noted that the electrical contact between the charging electrode on the base station 200 and the charging electrode on the cleaning device 100 does not mean that the base station 200 starts charging the battery of the cleaning device 100. At this time, only a small current can be passed to determine that the cleaning device 100 is in place.

[0032] In the embodiment of the present application, when the cleaning system is in the dust collection mode, the roller brush motor is configured to drive the roller brush 140 to rotate, so as to disturb the airflow entering the dust box 110 and change the flow direction of the airflow, thereby making the airflow entering the dust box 110 flow irregularly, blowing up the garbage originally in the corner of the accommodating chamber 111, so that the garbage is easier to enter the dust collecting chamber 210 through the dust outlet 113 and the dust collecting channel 300 under the action of the second fan 220, thereby significantly improving the dust collection effect of the base station 200. Specifically, the roller brush 140 can be driven to rotate when the second fan 220 works alone or when the first fan 120 is started (that is, when the first fan 120 and the second fan 220 work at the same time).

[0033] It should be noted that the driving of the roller brush 140 to rotate mentioned here may be driving the roller brush 140 to rotate continuously in the first direction, or driving the roller brush 140 to rotate alternately in the first direction and the second direction. When the roller brush is driven to rotate alternately in the first direction and the second direction, the roller brush 140 rotates in the first direction for a first time (e.g., 5 seconds or other suitable time), and then rotates in the second direction for a second time (e.g., 5 seconds or other suitable time, and the second time may be less than or equal to the first time), and so on and so forth. Compared with the roller brush continuously rotating in the first direction, the roller brush 140 rotating alternately in the first direction and the second direction can better disturb the airflow entering the dust inlet channel 130 (i.e., entering the dust inlet port 112), so that the garbage is more likely to enter the dust collecting chamber 210 through the dust outlet port 113 and the dust collecting channel 300 under the action of the second fan 220, thereby significantly improving the dust collection effect of the base station 200. The roller brush 140 rotates alternately in the first direction and the second direction and can also effectively clean the residual hair or other foreign matter on the roller brush 140, ensuring that the roller brush 140 is in a relatively clean state during the next cleaning. It should be noted that when the roller brush motor drives the roller brush 140 to rotate alternately in the first direction and the second direction, it first drives the roller brush 140 to rotate in the first direction, so that the garbage adhered to the roller brush enters the dust box 110 and the dust collecting chamber 210 under the action of the airflow, and prevents the garbage from being thrown out.

[0034] See attached Figure 4 In the embodiment of the present application, the cleaning device 100 further includes a battery, which is electrically connected to the first fan 120 and the roller brush motor to power them. The base station 200 further includes a power supply circuit, which is connected to the mains and the second fan 220 to receive the mains and power the second fan 220. When the cleaning system is in the dust collection mode, the battery supplies power to the first fan 120, and the power supply circuit supplies power to the second fan 220. The base station 200 further includes a charging circuit, which is connected to the mains. When the cleaning device 100 is in a preset position in the base station 200, the charging circuit is electrically connected to the battery, and the charging circuit can charge the battery. The cleaning system also has a charging mode, and when the cleaning system is in the charging mode, the charging circuit charges the battery. In the embodiment of the present application, when the cleaning system is in the dust collection mode, the charging circuit is disabled, that is, the charging circuit does not charge the battery of the cleaning device 100 when the cleaning system is in the dust collection mode, and the charging circuit can be configured to charge the battery of the cleaning device 100 when the dust collection is completed and the cleaning system is in the non-dust collection mode. In this way, when the cleaning system is in the dust collection mode, most of the electric energy received by the base station 200 can be used to power the second fan 220, so that the second fan 220 can operate at a higher power, thereby improving the dust collection effect and avoiding the charging circuit taking away part of the electric energy, causing the power of the second fan 220 to be reduced.

[0035] In the embodiment of the present application, there are two first fans 120, both of which are connected to the dust box 110, and the two first fans 120 are configured to start simultaneously after the second fan 220 works for a preset time, so as to increase the air flow rate and flow rate in the accommodating chamber 111 of the entire dust box 110, so that the garbage in the accommodating chamber 111 can more easily enter the dust collecting chamber 210 through the dust outlet 113 and the dust collecting channel 300 under the action of the second fan 220. In the embodiment of the present application, the dust box 110 has a first air outlet and a second air outlet on both sides, and the air inlets of the two first fans 120 are connected to the first air outlet and the second air outlet respectively, and the first air outlet and the second air outlet are arranged in different directions, so that the airflows formed by the two first fans 120 can flow out of the dust box 110 in different directions. When the cleaning system is in the dust collection mode and the two first fans 120 and the second fans 220 are working at the same time, the airflow entering the accommodating chamber 111 of the dust box 110 will be divided into three streams, one stream entering the first fan 120 through the first air outlet, another stream entering the second fan 220 through the second air outlet, and another stream entering the dust collecting chamber 210 through the dust outlet 113 and the dust collecting channel 300. The three streams of air greatly increase the air velocity and flow rate in the entire accommodating chamber 111. The greater air velocity and flow rate can carry more garbage or heavier garbage. The airflows in different directions can effectively disturb the garbage in the dust box 110, so that the garbage in the accommodating chamber 111 is easier to enter the dust collecting chamber 210 through the dust outlet 113 and the dust collecting channel 300 under the action of the second fan 220, thereby greatly improving the cleanliness of the dust box 110, increasing the service life of the dust box 110, reducing the number of times the user cleans the dust box 110, and improving the user experience.

[0036] In the embodiment of the present application, the dust inlet 112 and the dust outlet 113 are located in the dust box 110 in the third direction (i.e. Figure 2 The first air outlet and the second air outlet are located on both sides of the dust box 110 in the fourth direction (i.e. Figure 2The third direction may be perpendicular or non-perpendicular to the fourth direction. Thus, when the cleaning system is in the dust collection mode and the two first fans 120 and the second fans 220 are working at the same time, the airflow velocity in the third direction will increase significantly, especially near the dust inlet 112. The airflow generated by the two first fans 120 can make the garbage in the dust box 110 tend to move between the first air outlet and the second air outlet, that is, move to the flow path of the airflow generated by the second fan 220. The airflow generated by the second fan 220 can better push the garbage in the accommodating chamber 111 to move along the third direction (that is, move in the direction from the dust inlet 112 to the dust outlet 113), thereby better pushing the garbage in the accommodating chamber 111 to enter the dust collecting chamber 210 through the dust outlet 113 and the dust collecting channel 300, thereby improving the dust collection effect of the base station 200. In some other embodiments, the number of the first fan 120 can also be one. In some other embodiments, the air inlet may be located at the top of the dust box 110 (i.e., the side of the dust box 110 away from the surface to be cleaned). In some other embodiments, the dust outlet 113 may be located at the bottom of the dust box 110, i.e., the side of the dust box 110 facing the surface to be cleaned. The specific positions of the dust inlet 112, the dust outlet 113, and the air outlet on the dust box 110 may be flexibly adjusted by those skilled in the art according to the design requirements of the cleaning device 100 and the base station 200.

[0037] In some embodiments, when there are two first fans 120, the two first fans 120 can be configured to work alternately after the second fan 220 works for a preset time, that is, one first fan 120 is first started and works for a third time (e.g., 10 seconds or other suitable time), then the first fan 120 is turned off, and the other first fan 120 is started and works for a fourth time (e.g., 10 seconds or other suitable time), and then turned off, and so on. In this way, on the one hand, the flow direction of the airflow in the dust box 110 can be changed, and the garbage in the accommodating chamber 111 can be disturbed, so that it is easier to enter the dust collecting chamber 210 through the dust outlet 113 and the dust collecting channel 300 under the action of the second fan 220; on the other hand, it can prevent some garbage from being continuously adsorbed on the filter element at the corresponding air outlet under the action of the first fan 120.

[0038] The present application also provides a dust collection method for a cleaning system, and the cleaning system may be the cleaning system in the above embodiment, see the attached Figure 5 , the dust collection method comprises the following steps:

[0039] S100: When the cleaning system is in the dust collection mode, the second fan 220 is controlled to operate.

[0040] Specifically, in an embodiment of the present application, when a specific button corresponding to the dust collection mode on the base station 200 is triggered, the cleaning system enters the dust collection mode. In some other embodiments, the cleaning system may automatically enter the dust collection mode when other preset trigger conditions are met. When the cleaning device 100 is in the dust collection mode, the dust collection chamber 210 is connected to the dust box 110, and the second fan 220 is controlled to start working. At this time, the first fan 120 does not work, and the airflow enters the dust collection chamber 210 from the outside of the cleaning device 100 through the dust inlet channel 130, the dust inlet port 112, the accommodating chamber 111, the dust outlet port 113, and the dust collection channel 300 in sequence (the direction of the airflow is as shown in FIG. 2 ). Figure 1 The airflow preferentially takes away the fine dust and some garbage in the accommodating cavity 111 of the dust box 110 and makes them enter the dust collecting cavity 210, which can effectively prevent the dust from passing through the filter element at the air outlet of the dust box 110, thereby increasing the service life of the filter element.

[0041] S200: After the second fan 220 works for a preset time, the first fan 120 is controlled to start.

[0042] Specifically, in the embodiment of the present application, after the second fan 220 works for a preset time, for example, 10 seconds or other suitable time, the first fan 120 is controlled to start working. At this time, the first fan 120 and the second fan 220 work simultaneously. At this time, a part of the airflow entering the accommodating chamber 111 through the dust inlet channel 130 and the dust inlet port 112 enters the dust collecting chamber 210 through the dust outlet port 113 and the dust collecting channel 300 (the flow direction of the airflow is as shown in FIG. 2 ). Figure 2 A in the figure), another part of the airflow enters the first fan 120 through the air outlet on the dust box 110, and is discharged through the air outlet of the first fan 120 (the direction of the airflow is shown in FIG. Figure 2 B). The simultaneous operation of the first fan 120 and the second fan 220 can significantly increase the velocity and flow rate of the airflow in the accommodating chamber 111, thereby being able to carry heavier garbage, so that it can enter the dust collecting chamber 210 through the dust outlet 113 and the dust collecting channel 300 under the action of the second fan 220, thereby improving the dust collection effect of the base station 200. In the embodiment of the present application, there are two first fans 120, and after the second fan 220 has been working for a preset time, the two first fans 120 are controlled to start simultaneously.

[0043] In an embodiment of the present application, the dust collection method further includes:

[0044] S300: Control the roller brush motor to drive the roller brush 140 to rotate.

[0045] Specifically, step S300 can be performed when step S100 or step S200 is performed, that is, when the second fan 220 is working alone or the first fan 120 is started (that is, when the first fan 120 and the second fan 220 are working simultaneously), the roller brush 140 is driven to rotate. It should be noted that the driving of the roller brush 140 to rotate here can be driving the roller brush 140 to rotate continuously in the first direction, or driving the roller brush 140 to rotate alternately in the first direction and the second direction. When the roller brush is driven to rotate alternately in the first direction and the second direction, the roller brush 140 rotates in the first direction for a first time (for example, 5 seconds or other suitable time), and then rotates in the second direction for a second time (for example, 3 seconds or other suitable time, and the second time can be less than or equal to the first time), and so on. The roller brush 140 rotates alternately in the first direction and the second direction to disturb the airflow entering the dust inlet channel 130 (that is, entering the dust inlet port 112), changing the flow direction of the airflow, thereby making the airflow entering the accommodating chamber 111 flow irregularly, blowing up the garbage originally in the corner of the accommodating chamber 111, making it easier for the garbage to enter the dust collecting chamber 210 through the dust outlet port 113 and the dust collecting channel 300 under the action of the second fan 220, thereby significantly improving the dust collection effect of the base station 200. The roller brush 140 rotates alternately in the first direction and the second direction and can also effectively clean the residual hair or other foreign matter on the roller brush 140, ensuring that the roller brush 140 is in a relatively clean state when cleaning next time.

[0046] In some embodiments, the cleaning device 100 has two first fans 120, and step S200 may include:

[0047] S210: After the second fan 220 works for a preset time, one of the first fans 120 is controlled to work for a third time, wherein the third time may be 10 seconds or other suitable time, and when the first fan 120 is working, the other first fan 120 is turned off.

[0048] S220: Turn off the first fan 120, control another first fan 120 to work for a fourth time, and then turn off the first fan 120. The fourth time may be 10 seconds or other suitable time.

[0049] S230: loop through steps S210 and S220.

[0050] In this way, on the one hand, the direction of the airflow in the accommodating chamber 111 can be changed, thereby disturbing the garbage in the accommodating chamber 111, making it easier for the airflow to enter the dust collecting chamber 210 through the dust outlet 113 and the dust collecting channel 300 under the action of the second fan 220; on the other hand, it can prevent some garbage from being continuously adsorbed on the filter element at the corresponding air outlet under the action of the first fan 120.

[0051] According to laboratory data, when the power of the second fan 220 is 650W, if the second fan 220 is replaced with a 1000W fan and only the second fan 220 is turned on for dust collection, the dust collection rate of mixed garbage is only increased from 78% to 90%, the dust collection rate of DPU ash (test dust) is only increased from 30% to 47%, and the dust collection rate of household ash is increased from 90% to 96%. When the power of the second fan 220 is 650W, the dust collection method of the embodiment of the present application is used to collect dust, compared with only turning on the second fan 220 for dust collection, the dust collection rate of mixed garbage can be increased from 78% to 99.5%, the dust collection rate of DPU ash (test dust) can be increased from 30% to 76%, and the dust collection rate of household ash can be increased from 90% to 95%. It can be seen that the dust collection method of the embodiment of the present application can significantly improve the dust collection effect of the base station 200 without changing the power of the second fan 220. Compared with the technical solution of using a higher-power second fan 220, it has better dust collection effect and lower cost, and has significant economic benefits.
