Detailed implementation manners

[0040] The present application relates to a vacuum cleaning system, which mainly consists of two parts: a vacuum cleaner and a base station; after the vacuum cleaner performs the dust suction work, it can be sent back to the base station for storage; and during the storage of the vacuum cleaner in the base station, the dust in the dust collection cup can be cleaned; the cleaning of the dust mainly includes emptying the debris in the dust collection cup and using the "blowing" method to remove the debris that may adhere to the inner wall of the dust collection cup, so that it leaves the corresponding wall. The dust cleaning solution of the present application can prevent the user's hands from touching the dust in the dust collection cup, and since the base station itself does not configure a vacuum suction system, the cost is low.

[0041] Figure 1-2 Fig. shows a schematic example of a vacuum cleaning system of the present application. The vacuum cleaning system consists of a vacuum cleaner 100 and a base station 900. In this example, the vacuum cleaner 100 is a portable handheld vacuum cleaner, which can be connected to accessories such as a suction tube and a suction head to perform dust suction work on different surfaces to be cleaned. The base station 900 is configured to be able to dock with and receive the vacuum cleaner 100; thus, when the vacuum cleaner 100 is not in use, it can be stored at the base station 900; during the docking of the vacuum cleaner 100 at the base station 900, the vacuum cleaner 100 can perform tasks such as charging and dust cleaning.

[0042] See Figure 3 And Figure 4 , which shows a schematic example of a vacuum cleaner of the present application. The vacuum cleaner 100 mainly includes a housing 1, a dust collection cup 2 and a suction motor 3.

[0043] The suction motor 3 can generate a vacuum negative pressure to promote the flow of air; for example: promoting the flow of dusty air to flow in from a dirty air inlet, entering the dust collection cup 2 and passing through the suction motor 3.

[0044] The vacuum cleaner 100 further includes a power supply 4, which is electrically connected to the suction motor 3 to provide power to the suction motor 3. In this example, the power supply 4 may include one or more rechargeable batteries. In other embodiments, the power supply may also be a power supply component including a power lead that can be connected to an external socket.

[0045] The housing 1 is usually a component assembled from a plurality of injection molded parts. In this example, the housing 1 has a handle 11 for the user to hold. The housing 1 is also provided with a first air inlet 12, a second air inlet 13 and an exhaust port 14, all of which are connected to the outside air.

[0046] The first air inlet 12 can be connected to a suction nozzle accessory (not shown in the figure) to use the external suction nozzle accessory to send dust and air from the surface to be cleaned into the vacuum cleaner 100. The second air inlet 13 is a mouth away from the first air inlet 12, which can directly send clean air from the outside to the suction motor 3 without passing through the dust cup 2. The exhaust port 14 can discharge the air flowing out of the suction motor 3 into the outside air.

[0047] The dust cup 2 is usually a component composed of multiple parts, and a dust collecting chamber 21 is formed inside the dust cup 2. An air inlet 22 in fluid communication with the dust collecting chamber 21 is provided on the side wall of the dust cup 2, and an air outlet 25 is provided on the top of the dust cup 2. The air inlet 22 is preferably configured to introduce the airflow into the dust collecting chamber 21 in a spiral air intake manner. A filter 23 is also provided at the inner upper part of the dust cup 2. The airflow entering the dust collecting chamber 21 will escape from the air outlet 25 after being filtered by the filter 23. In this example, a dust cover 24 that can be switched between an open cover position for opening the dust collecting chamber 21 and a closed cover position for closing the dust collecting chamber 21 is also provided at the lower end of the dust cup 2. A locking block 26 for keeping the dust cover 24 in the closed cover position is provided at the lower part of the side wall of the dust cup 2. By applying a force to the locking block 26, the dust cover 24 can be released from the closed cover position to enter the open cover position. In some preferred embodiments, the dust cup 2 is detachably connected to the housing 1 .

[0048] The suction motor 3 is fixedly mounted on the inner side of the upper part of the housing 1. The suction motor 3 is generally a component consisting of a motor part and an impeller part, and has a suction end 31 and an exhaust end 32. After the suction motor 3 is started, the impeller part will produce negative pressure at the suction end 31, thereby driving the air flow from the suction end 31 to the exhaust end 32.

[0049] In the vacuum cleaner 100, a plurality of fluid passages for fluid flow are constructed between the housing 1, the dust cup 2 and the suction motor 3; see Figure 4 , Figure 5 , Figure 7 and Figure 8 , several fluid pathways including: The first air suction flow path 41 starts from the first air inlet 12, passes through the air inlet 22, the dust collection chamber 21, and the air outlet 25 of the dust collection cup 2, and reaches the suction end 31 of the suction motor 3. The first air suction flow path 41 includes an upstream fluid passage 411 located upstream of the dust collection chamber 21 and between the first air inlet 12 and the air inlet 22, and a downstream fluid passage 412 located downstream of the dust collection chamber 21 and between the air outlet 25 and the suction end 31.

[0050] The first air discharge flow path 42 is located between the exhaust end 32 of the suction motor 3 and the exhaust port 14.

[0051] The second air suction flow path 43 is located between the second air inlet 13 and the suction end 31. The second air suction flow path 43 starts from the second air inlet 13 and bypasses the dust collection chamber 21.

[0052] The second air discharge flow path 44 is located between the exhaust end 32 and the dust collection chamber 21. The second air discharge flow path 44 can blow the air discharged from the suction motor 3 into the dust collection chamber 21.

[0053] In order to control these flow paths, a flow path control device is also provided in the vacuum cleaner 100. The flow path control device in this example includes a first valve 51 provided in the downstream fluid passage 412 of the first air suction flow path 41, a second valve 52 provided in the second air suction flow path 42, and a third valve 53 provided in the second air discharge flow path 43.

[0054] By controlling these valves, it is possible to select between opening and closing the corresponding flow paths. Specifically as follows: When the first valve 51 is selected to be opened, outside air (usually dust-containing air) will be able to be sucked in from the first air inlet 12, pass through the air inlet 22, the dust collection chamber 21, the air outlet 25 in sequence, and reach the suction end 31 of the suction motor 3; when the first valve 51 is selected to be closed, the outside air is blocked from entering the dust collection chamber 21 along the upstream fluid passage 411.

[0055] When the second valve 52 is selected to be opened, outside air (usually dust-containing air) will be able to pass through the second air inlet 13 in sequence and reach the suction end 31 of the suction motor 3; when the second valve 52 is selected to be closed, the outside air is blocked from entering the suction end 31 from the second air suction flow path 43.

[0056] When the third valve 53 is selected to be opened, the air discharged from the exhaust end 31 of the suction motor 3 will be able to be sent into the dust collection chamber 21; when the third valve 53 is selected to be closed, the air discharged from the exhaust end 31 is blocked from flowing along the second air discharge flow path 44.

[0057] In the solution of the flow path control device composed of multiple valves, these valves can be either electronic valves or mechanical valves. If electronic valves are selected, they can be controlled separately or jointly by setting up a control circuit. If mechanical valves are selected, the user can manually or with the aid of a controllable electric component (such as a motor) to control these valves. Based on this, the flow path control device can be configured to respond to the user's operation to change the open / closed states of multiple valves, or can be configured to respond to a switch to automatically change the open / closed states of multiple valves.

[0058] See Figure 4 and Figure 5 As shown, it shows an example of the setting of a first valve 51, a second valve 52 and a third valve 53 of the present application.

[0059] In this example, the first valve 51 and the second valve 52 are integrated on a first movable member 54 that can be changed between a first position and a second position.

[0060] As Figure 5 shown, when the first movable member 54 is in the first position, the first valve 51 is open, the first air intake flow path 41 is unblocked, while the second valve 52 is closed and the second air intake flow path 43 is blocked. As Figure 8 shown, when the first movable member 54 is in the second position, the first valve 51 is closed, the second valve 52 is open, the first air intake flow path 41 is blocked, and the second air intake flow path 43 is unblocked.

[0061] The first movable member 54 can be designed as a rotatable member, such as a seesaw member. The first valve 51 and the second valve 52 are respectively located at opposite ends of the member.

[0062] In order to control the first movable member 54, a movable ejector rod 55 is also provided on the vacuum cleaner 100, and the ejector rod 55 is linked with the first movable member 54. One end of the ejector rod 55 abuts against the first movable member 54, and the other end is located outside the housing 1. The user can manually or with the aid of an external component control the movement of the first movable member 54, so as to control the first valve 51 and the second valve 52.

[0063] The third valve 53 is integrated on a second movable member 56 that can be changed between a first state and a second state.

[0064] As Figure 5 shown, when the second movable member 56 is in the first state, the third valve 53 is closed, and the air discharged from the exhaust end 31 will be prevented from being sent to the dust collection chamber 21 via the second air discharge flow path 44. As Figure 8As shown, when the second movable member 56 is in the second state, the third valve 53 is opened, and the air discharged from the exhaust end 31 will be able to be sent to the dust collection chamber 21 via the second air discharge flow path 44.

[0065] The second movable member 56 can also be designed as a rotatable member. In this example, for the convenience of controlling the second movable member 56, a part of the second movable member 56 is constructed to extend outside the housing 1.

[0066] In some embodiments provided by the present application, the second air discharge flow path 44 passes through the air inlet 22, that is, the air discharged from the exhaust end 32 is sent into the dust collection chamber 21 via the air inlet 22.

[0067] In some embodiments provided by the present application, the second air discharge flow path 44 intersects with the upstream fluid passage 411 of the first air suction flow path 41. The third valve 53 is a multi-way valve and is arranged at the intersection of the second air discharge flow path 44 and the upstream fluid passage 411. When the third valve 53 is opened, the second air discharge flow path 44 is penetrated and the upstream fluid passage 411 is cut off; when the third valve 53 is closed, the second air discharge flow path 44 is cut off and the upstream fluid passage 411 is penetrated.

[0068] In some embodiments provided by the present application, the flow path control device further includes a wind deflector 57 arranged on the second air discharge flow path 44. The wind deflector 57 is configured to open when the air pressure entering the second air discharge flow path 44 is greater than or equal to a predetermined pressure; for example, when the exhaust port 14 is closed and the air output from the exhaust end 32 of the exhaust fan 3 is sent into the second air discharge flow path 44, as the air pressure increases, the wind deflector 57 will automatically open.

[0069] The flow path control device of the present application is not limited to the above solutions, and it can also be other solutions, such as directly arranging a controllable valve in the first air discharge flow path to directly control the on and off of the first air discharge flow path by means of the valve. In addition, the third valve is not limited to being arranged at the intersection of the second air discharge flow path and the upstream fluid passage, and it can also be a multi-way valve arranged at the exhaust end.

[0070] Based on the vacuum cleaner structure described above, the vacuum cleaner 100 is configured to be able to selectively execute a dust suction mode and an ash removal mode.

[0071] Such as Figure 4 、 Figure 5As shown, when the vacuuming mode is selected for execution, the first valve 51 is selectively opened, the second valve 52 and the third valve 53 are selectively closed, the first air suction flow path 41 and the first air discharge flow path 42 are in communication, and the second air suction flow path 43 and the second air discharge flow path 43 are blocked; for the suction motor 3, outside air 600 will be able to be introduced from the first air inlet 12 and sequentially pass through the air inlet 22, the dust collection chamber 21, the filter 23, the suction end 31, the exhaust end 32 to reach the exhaust port 14, and will ultimately be discharged to the outside atmosphere via the exhaust port 14.

[0072] As Figure 7 , Figure 8 shown, in the dust removal mode, the first valve 51 is selectively closed, the second valve 52 and the third valve 53 are selectively opened, and the first air suction flow path 41 is blocked; at the same time, the second air suction flow path 43 and the second air discharge flow path 43 are in communication. For the suction motor 3, outside air 700 will be introduced from the second air inlet 13 and sequentially pass through the suction end 31, the exhaust end 32, the air inlet 22 to reach the dust collection chamber 21. When the dust cover 24 of the dust collection chamber 21 is opened, the large-volume dust 800 accumulated in the dust collection chamber 21 will first fall, and the garbage 801 adhering to the inner wall of the dust collection chamber 21 or the filter 23 will be blown off the adhering wall surface by the air 700 and fall from the dust collection chamber 21 together with the air 700, thus completing the dust cleaning work of the dust collection chamber.

[0073] To ensure the amount of air entering the dust collection chamber 21 in the dust removal mode, it is recommended to close the exhaust port 14 or use a component (such as a controllable valve) to block the first air discharge flow path 41, so that all the air flowing out from the exhaust end 32 enters the dust collection chamber 21 to maximize the dust blowing effect.

[0074] As Figure 1 , 2 , 7, and 8 shown, the base station 900 includes an upright body 91, a triggering device 92, and a garbage receiving container 93.

[0075] The body 91 is configured to be able to be supported on a plane, such as the ground; the upper part of the body 91 has a docking portion 911 for docking with the vacuum cleaner 100.

[0076] The triggering device 92 includes a first triggering portion 921, a second triggering portion 922, and a third triggering portion 923. When the vacuum cleaner 100 is docked with the base station 900, the first triggering portion 921 contacts the ejector rod 55, the second triggering portion 922 contacts the second movable member 56, and the third triggering portion 923 contacts the lock block 26 on the dust collection cup 2.

[0077] As Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, when the vacuum cleaner 100 docks with the base station 900, the docking part 911 closes the exhaust port 14. The push rod 55 drives the first movable part 54 to change from the first position to the second position in response to contact with the first trigger part 921, that is, the first valve 51 is closed and the second valve 52 is opened. The second movable part 56 changes from the first state to the second state in response to contact with the second trigger part 922, that is, the third valve 53 is opened. The third trigger part 923 changes the dust cover 24 from the closed position to the open position in response to contact with the lock block 26 of the dust collection cup 2. At this time, the vacuum cleaner 100 is ready to run the ash removal mode. By controlling the suction motor 3 to start, the dust cleaning work for the dust collection cup 2 can be performed.

[0078] The structure of the triggering device of the present application is not limited to the above scheme, and it can be adaptively changed according to the need to control multiple valves on the vacuum cleaner.

[0079] The garbage receiving container 93 is supported on the body 91. The garbage receiving container 93 is engaged with the dust collection cup 2 when the vacuum cleaner 100 docks with the base station 900 and is configured to be able to receive debris falling from the dust collection chamber 21.

[0080] The garbage receiving container 93 of the present application includes a dust box 932 with an escape hole 931 and a dust bag 933 located in the dust box 932. In some embodiments, the garbage receiving container can also be set as a dust box with an escape hole, and a filter, such as a HEPA filter, can be provided at the escape hole.

[0081] The vacuum cleaner 100 in the present application is configured to be inserted into the base station 900 in a top-down direction and form a docking with the base station 900. In other embodiments, the vacuum cleaner 1 can also be configured to be inserted into the base station in an inclined manner, which requires ensuring that the garbage receiving container is located below the dust collection cup and docks with it, so that when the dust cover is opened, the debris can fall into the garbage receiving container.

[0082] In some embodiments, the valve components in the flow path can be multiple single-pass valves or one or more multi-pass valves.
