[0035] The present application will be further described in detail below in conjunction with the drawings through specific implementation manners. Similar elements in different implementation manners adopt related similar element numbers. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods.

For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the art.

[0036] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment and do not mean that they are necessary sequences, unless it is stated that a certain sequence must be followed.

[0037] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0038] In one embodiment, please refer to Figures 1 to 4 The cleaning system includes a dust collecting base station 2 and a handheld vacuum cleaner 1. The handheld vacuum cleaner 1 includes a dust cup assembly and a vacuum cleaner fan 12. The dust cup assembly includes a dust cup 11. The vacuum cleaner fan 12 is used to generate a suction airflow. The dust collecting base station 2 includes a base station fan 21. The dust collecting base station 2 has a base station dust collecting chamber 22 for collecting dust. When the handheld vacuum cleaner 1 needs to clean the dust in the dust cup 11, at least part of the handheld vacuum cleaner 1 is installed to the dust collecting base station 2, and the base station fan 21 of the dust collecting base station 2 is started to suck out the garbage in the dust cup 11.

[0039] In one embodiment, please refer to Figure 6 and Figure 7 The dust cup assembly includes a first cover 13 and a one-way valve structure 10. The dust cup 11 has a first dust collecting chamber 112 and a second dust collecting chamber 116 disposed inside the first dust collecting chamber 112. The first dust collecting chamber 112 has a first discharge port 1121 for discharging garbage. The second dust collecting chamber 116 has a second discharge port 1161 for discharging garbage. The second discharge port 1161 is located in the first dust collecting chamber 112 and can be communicated with the first dust collecting chamber 112. The first discharge port 1121 and the second discharge port 1161 are arranged at intervals. By staggering the first discharge port 1121 and the second discharge port 1161, the influence of the second discharge port 1161 on the first discharge port 1121 is reduced, and the garbage is discharged from the first discharge port 1121 more smoothly and is less likely to get stuck.

[0040] The first cover 13 is disposed at the first discharge outlet 1121. When the handheld vacuum cleaner 1 is used for vacuuming, the first cover 13 is closed so that the first dust collecting chamber 112 can normally collect dust. The first cover 13 is opened after the handheld vacuum cleaner 1 is mounted on the dust collecting base station 2, so that the garbage in the first dust collecting chamber 112 can be discharged from the first discharge outlet 1121 to the dust collecting base station 2.

[0041] The one-way valve structure 10 is provided at the second row of outlets 1161. The one-way valve structure 10 has an open state and a closed state. When the one-way valve structure 10 is in the open state, the garbage in the second dust collection chamber 116 is discharged from the second row of outlets 1161. When the one-way valve structure 10 is in the closed state, it covers the second row of outlets 1161. The one-way valve structure 10 can be opened when the base fan 21 of the dust collection base station 2 starts to suck the first dust collection chamber 112. That is to say, the one-way valve structure 10 allows the dust flow to be discharged unidirectionally from the second row of outlets 1161. When the base fan 21 stops sucking the first dust collection chamber 112, the one-way valve structure 10 closes, and the dust flow cannot enter the second dust collection chamber 116 from the second row of outlets 1161. The one-way valve structure 10 at the second row of outlets 1161 enables the handheld vacuum cleaner 1 to perform the dust suction work normally, and the garbage in the first dust collection chamber 112 will not be sucked away by the vacuum cleaner fan 12 through the second row of outlets 1161.

[0042] In one embodiment, by controlling the air pressure difference between the first dust collection chamber 112 and the second dust collection chamber 116, the state of the one-way valve structure 10 is controlled. Specifically, after the base fan 21 sucks the first dust collection chamber 112, a negative pressure can be generated in the first dust collection chamber 112, and the one-way valve structure 10 is opened under the action of the negative pressure. Of course, in one embodiment, when the base fan 21 is turned on, the vacuum cleaner fan 12 can also be turned on. At this time, under the action of the negative pressure in the first dust collection chamber 112, the one-way valve structure 10 can still be opened. In one embodiment, the power of the base fan 21 is greater than the power of the vacuum cleaner fan 12. In this way, when the base fan 21 and the vacuum cleaner fan 12 are turned on simultaneously, the base fan 21 can still suck the garbage in the first dust collection chamber 112. Specifically, in one embodiment, after the handheld vacuum cleaner 1 is installed with the dust collection base station 2, the base fan 21 and the vacuum cleaner fan 12 are alternately turned on for operation.

[0043] Further, in one embodiment, please refer to Figure 7 , the one-way valve structure 10 includes an elastic valve sheet 101 and a support frame 102; the support frame 102 is on the side of the elastic valve sheet 101 facing the second dust collection chamber 116, and is used to support the elastic valve sheet 101 to keep the one-way valve structure 10 in the closed state; the elastic valve sheet 101 makes at least part of the elastic valve sheet 101 move away from the second dust collection chamber 116 through elastic deformation to open the second row of outlets 1161. When the one-way valve structure 10 is in the closed state, the support frame 102 supports the elastic valve sheet 101, so that the elastic valve sheet 101 cannot move into the second dust collection chamber 116 and can only move away from the second dust collection chamber 116. When the first dust collection chamber 112 is evacuated by the base fan 21, the pressure difference on both sides of the elastic valve sheet 101 can cause the elastic valve sheet 101 to deform and move away from the second dust collection chamber 116, thereby opening the second row of outlets 1161.

[0044] In one embodiment, the support frame 102 includes a support ring 1021 in the middle and support arms 1022 connected to the support ring 1021, and there are multiple support arms 1022. In one embodiment, the support arms 1022 are evenly arranged along the circumferential direction of the support ring 1021. In some other embodiments, the support frame 102 can also be a grid structure.

[0045] Further, in one embodiment, please refer to Figure 7 and Figure 9 , the elastic valve sheet 101 includes a fixed part 1011 and a movable part 1012. The fixed part 1011 is fixed at the second discharge port 1161, and the thickness of the fixed part 1011 is greater than that of the movable part 1012. The movable part 1012 can elastically deform so that the movable part 1012 can swing away from the second dust collection chamber 116 to open the second discharge port 1161.

[0046] Specifically, in one embodiment, please refer to Figure 7 and Figure 9 , the fixed part 1011 is a valve sheet ring, the movable part 1012 is a movable sheet in the valve sheet ring. A part of the movable sheet is connected to the valve sheet ring, and there is a gap between a part of the movable sheet and the valve sheet ring. The part where there is a gap between the movable sheet and the valve sheet ring can move relative to the valve sheet ring, and the part where the movable sheet is connected to the valve sheet ring can elastically deform. In some other embodiments, the elastic valve sheet 101 can also be strip-shaped, and the movable part 1012 and the fixed part 1011 are arranged in sections.

[0047] Further, in one embodiment, please refer to Figure 7 and Figure 9 , the fixed part 1011 and the movable part 1012 are integrally formed. In some other embodiments, the fixed part 1011 and the movable part 1012 can also be connected together by welding, bonding or fixing with fasteners.

[0048] Further, in one embodiment, please refer to Figure 7 , the dust cup assembly includes a mounting seat 103 at the second discharge port 1161. The support frame 102 is connected to the mounting seat 103. The dust cup assembly includes a fixing member 104, and the fixed part 1011 is clamped between the mounting seat 103 and the fixing member 104. In one embodiment, one end of the support arm 1022 is connected to the mounting seat 103.

[0049] Specifically, in one embodiment, the support frame 102 and the mounting seat 103 can adopt any feasible connection method. For example, the support frame 102 and the mounting seat 103 can be integrally formed. For another example, the support frame 102 and the mounting seat 103 can also be bonded, welded or fixed with fasteners.

[0050] In one embodiment, please refer toFigure 7 and Figure 9 , the fixing member 104 is a compression ring, and the size of the compression ring matches the size of the valve disc ring, so that the compression ring can cooperate with the mounting seat 103 to clamp the valve disc ring.

[0051] In one embodiment, please refer to Figure 7 , the mounting seat 103 has a positioning groove. When the elastic valve disc 101 is installed, the fixing portion 1011 is positioned and placed in the positioning groove, and then the fixing member 104 is pressed on the fixing portion 1011, and the fixing member 104 can be fixed on the mounting seat 103 through a fastener. In one embodiment, please refer to Figure 7 , the mounting seat 103 includes a positioning post 1031 in the positioning groove. The fixing portion 1011 has a positioning hole for the positioning post 1031 to pass through. The positioning post 1031 has a fixing hole 1032, and the fastener passes through the compression ring and is screwed into the fixing hole 1032 to realize the fixing of the fixing portion 1011.

[0052] In addition to using the elastic valve disc 101, in one embodiment, please refer to Figure 10 and Figure 11 , the one-way valve structure 10 is a duckbill valve.

[0053] Specifically, in one embodiment, please refer to Figure 10 and Figure 11 , the duckbill valve is made of elastic soft rubber material. In one embodiment, the duckbill valve includes a first duckbill piece 105 and a second duckbill piece 106. The first duckbill piece 105 and the second duckbill piece 106 realize the opening and closing of the duckbill valve through relative movement; when the duckbill valve is in the closed state, the first duckbill piece 105 and the second duckbill piece 106 are attached to close the second discharge port 1161, and when the duckbill valve is in the open state, the first duckbill piece 105 and the second duckbill piece 106 are separated to open the second discharge port 1161.

[0054] In order to make the opening and closing of the first duckbill piece 105 and the second duckbill piece 106 more stable, in one embodiment, please refer to Figure 10 and Figure 11 , a first reinforcing rib 1051 is provided on the side of the first duckbill piece 105 facing away from the second duckbill piece 106, and a second reinforcing rib 1061 is provided on the side of the second duckbill piece 106 facing away from the first duckbill piece 105. In this way, the first duckbill piece 105 and the second duckbill piece 106 have higher strength, fit more closely after being combined, and have better reliability. In some other embodiments, only the first reinforcing rib 1051 may be provided on the side of the first duckbill piece 105 facing away from the second duckbill piece 106, or only the second reinforcing rib 1061 may be provided on the side of the second duckbill piece 106 facing away from the first duckbill piece 105.
