[0047] In one embodiment, please refer to Figures 1 to 5 , the cleaning system includes a handheld vacuum cleaner 1 and a dust collection base station 2, wherein the handheld vacuum cleaner 1 is used in cooperation with the dust collection base station 2, and at least a part of the handheld vacuum cleaner 1 is used to be mounted on the dust collection base station 2. The dust collection base station 2 includes a base fan 21, and the base fan 21 is used to suck out the garbage in the handheld vacuum cleaner 1, so that the dust collection base station 2 can suck the garbage in the handheld vacuum cleaner 1. The dust collection base station 2 and the handheld vacuum cleaner 1 will be introduced below in conjunction with the accompanying drawings.

[0048] In one embodiment, please refer to Figure 6 , the handheld vacuum cleaner 1 includes a dust suction cup 11 and a vacuum cleaner fan 12, and the vacuum cleaner fan 12 is used to generate a suction airflow.

[0049] Please refer to Figure 6 and Figure 7, the dust collection cup 11 has a dust cup air inlet 111 for allowing the dust flow to enter. Inside the dust collection cup 11, there is a first dust collection chamber 112 and a first cyclone separation chamber 113 connected to the dust cup air inlet 111. The first cyclone separation chamber 113 is used to perform cyclone separation on the incoming dust flow. The first dust collection chamber 112 is for the garbage separated by the first cyclone separation chamber 113 to enter. The first dust collection chamber 112 has a first discharge port 1121 for discharging the garbage.

[0050] When the handheld vacuum cleaner 1 is at least partially installed on the dust collection base station 2, the base station fan 21 of the dust collection base station 2 can operate simultaneously with the vacuum cleaner fan 12, so that the garbage in the first dust collection chamber 112 forms a chaotic dust flow, enabling the garbage in the first dust collection chamber 112 to enter the dust collection base station 2 through the first discharge port 1121. By simultaneously turning on the base station fan 21 and the vacuum cleaner fan 12, the base station fan 21 and the vacuum cleaner fan 12 suck in the garbage from different directions, and the garbage will be in a relatively chaotic state. Since the wind force of the fan of the dust collection base station 2 is greater, the garbage is sucked into the dust collection base station 2.

[0051] In order to improve the discharge efficiency of the garbage, in one embodiment, the power of the vacuum cleaner fan 12 is less than the power of the base station fan 21.

[0052] In one embodiment, please refer to Figure 3 , Figure 6 and Figure 7 , the dust collection base station 2 has a base station dust collection chamber 22. The base station dust collection chamber 22 is connected to the first dust collection chamber 112. The base station fan 21 can suck the garbage in the first dust collection chamber 112 into the base station dust collection chamber 22.

[0053] The vacuum cleaner fan 12 and the base station fan 21 can operate simultaneously in any feasible manner:

[0054] For example, in one embodiment, the dust collection base station 2 includes a base station communication module, and the handheld vacuum cleaner 1 includes a vacuum cleaner communication module. The vacuum cleaner communication module and the base station communication module are connected to each other. When the handheld vacuum cleaner 1 is installed on the dust collection base station 2, the dust collection base station 2 can send an instruction to turn on the vacuum cleaner fan 12 of the handheld vacuum cleaner 1 and turn on its own base station fan 21, thereby controlling the startup of the vacuum cleaner fan 12 and the base station fan 21.

[0055] For example, in one embodiment, both the vacuum cleaner communication module and the base station communication module are used to connect to a terminal device, so that the terminal device can control the handheld vacuum cleaner 1 and the dust collection base station 2 at the same time. Through the terminal device, the vacuum cleaner fan 12 and the base station fan 21 can be controlled to start. In one embodiment, a one-key start can be set on the terminal device, and through the one-key start, the vacuum cleaner fan 12 and the base station fan 21 can be turned on simultaneously. Specifically, in some embodiments, both the vacuum cleaner communication module and the base station communication module can also be Bluetooth modules; in some other embodiments, both the vacuum cleaner communication module and the base station communication module are WIFI modules.

[0056] For example, in one embodiment, first manually operate the switch of the handheld vacuum cleaner 1 to start the vacuum cleaner fan 12, and then manually operate the switch of the dust collection base station 2 to start the base station fan 21. After the vacuum cleaner fan 12 and the base station fan 21 work simultaneously for a target time, the garbage discharge of the handheld vacuum cleaner 1 is completed.

[0057] For another example, in one embodiment, the base station fan 21 can also be started first, and then the vacuum cleaner fan 12 can be started. Of course, the vacuum cleaner fan 12 can also be started after the base station fan 21 has been running for a period of time.

[0058] In one embodiment, please refer to Figure 6 and Figure 7 , a secondary cyclone separation device 114 is provided in the dust collection cup 11. The secondary cyclone separation device 114 has a second cyclone separation chamber 115 and a second dust collection chamber 116. The second dust collection chamber 116 is provided in the first dust collection chamber 112.

The second dust collection chamber 116 is for the garbage separated by the second cyclone separation chamber 115 to enter; the second dust collection chamber 116 has a second discharge port 1161 for discharging the garbage.

[0059] When at least part of the handheld vacuum cleaner 1 is installed in the dust collection base station 2, the base station fan 21 of the dust collection base station 2 can operate simultaneously with the vacuum cleaner fan 12, so that the garbage in the second dust collection chamber 116 can enter the dust collection base station 2 through the second discharge port 1161.

[0060] In one embodiment, please refer to Figure 6 and Figure 7 , the secondary cyclone separation device 114 includes a device housing 1141 and a cyclone cone 1142 located in the device housing 1141. The device housing 1141 includes a filter net 11421. After the dust flow is processed by the first cyclone separation chamber 113, it enters the device housing 1141 through the filter net 11421 and undergoes secondary separation in the second cyclone separation chamber 115. In one embodiment, please refer to Figure 6 andFigure 7 , there are multiple cyclone cones 1142.

[0061] In one embodiment, please refer to Figure 6 and Figure 7 , the first dust collection chamber 112 is located below the first cyclone separation chamber 113, the second dust collection chamber 116 is located below the second cyclone separation chamber 115, the first discharge port 1121 is located at the bottom of the first dust collection chamber 112, the second discharge port 1161 is located at the bottom of the second dust collection chamber 116, and the bottom of the second dust collection chamber 116 is suspended relative to the bottom of the first dust collection chamber 112. In one embodiment, the second discharge port 1161 is located in the first dust collection chamber 112 and can communicate with the first dust collection chamber 112, and the first discharge port 1121 is located below the second discharge port 1161. In this way, the influence of the second discharge port 1161 on the first discharge port 1121 is small, and the garbage is easier to be discharged from the first discharge port 1121 and is not easily stuck at the first discharge port 1121 to cause blockage.

[0062] In one embodiment, please refer to Figure 6 and Figure 7 , the handheld vacuum cleaner 1 further includes a dust cover 13 pivotally connected to the bottom of the dust cup 11. In one embodiment, the dust cover 13 covers the first discharge port 1121 to prevent the garbage in the first dust collection chamber 112 from being discharged.

[0063] In some other embodiments, the dust cover 13 can also cover the first discharge port 1121 and the second discharge port 1161 at the same time. At this time, both the first discharge port 1121 and the second discharge port 1161 need to be located at the bottom of the dust cup 11.

[0065] To improve stability, in one embodiment, please refer to Figure 6 and Figure 8, the handheld vacuum cleaner 1 further includes an elastic member 16, and the elastic member 16 is used to apply an elastic force to the clamping member 14 to keep the clamping member 14 clamping the dust collection cover 13. In this way, the clamping member 14 is not easily shaken, and the clamping member 14 can be kept in the position of clamping the dust collection cover 13, with better stability. In one embodiment, please refer to Figure 6 and Figure 8 , the elastic member 16 is a spring, and the spring is installed between the clamping member 14 and the dust collection cup 11. Specifically, the elastic member 16 is installed between the clamping member 14 and the dust collection cup 11 in a pre-compressed state so that the elastic member 16 can continuously apply an elastic force to the clamping member 14.

[0066] In some other embodiments, in addition to the elastic member 16, the dust collection cover 13 can also be kept in the closed state by magnetic attraction. After the handheld vacuum cleaner 1 is docked with the dust collection base station 2, under the action of the dust collection base station 2, the dust collection cover 13 can overcome the magnetic attraction force and open.
