DETAILED DESCRIPTION

[0020] In order to explain in detail the technical content, structural features, objectives and effects of the invention, the technical scheme in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0021] See also Figure 1 and Figure 2 , which illustrates the vacuum cleaner of the present application, which has a portable vacuum cleaner main unit 100. The portable vacuum cleaner main unit 100 includes a housing 1 with a handle 11, a cyclone separation device 2, a battery pack 3, a vacuum short pipe 4 and a suction motor 5.

[0022] The cyclone separation device 2 is arranged up and down with the suction motor 5. The cyclone separation device 2 is a two-stage cyclone separation device and includes a dust cup 21 and a filter core 22 located inside the dust cup 21. The dust cup 21 and the filter core 22 are both detachably arranged.

[0023] The battery pack 3 is used to supply energy to various energy-consuming components of the portable vacuum cleaner host 100 , such as the suction motor 5 .

[0024] The dust suction short pipe 4 is located at the front side of the housing 1 and is used to introduce the dust-laden airflow into the cyclone separation device 2 for air-ash separation.

[0025] The suction motor 5 can generate suction power to suck the dust-laden airflow from the dust suction short pipe 4 into the cyclone separation device 2. Since the suction motor 5 is a relatively common component in a vacuum cleaner, it will not be described in detail here.

[0026] See also Figure 3 The portable vacuum cleaner host 100 is also provided with an input device 8 and a control device 9. The control device 9 is configured to control the operation of the vacuum cleaner. The input device 12 is connected to the control device 9 so as to exchange information with the control device 9.

[0027] Continue as Figure 1 As shown, the input device 8 includes a display screen 81, a power start button 82 and an operation lever 83. The display screen 81 and the power start button 82 are located at the upper part of the housing 1 and close to the upper end of the handle 11. The power start button 82 is located inside the display screen 81.

[0028] The display screen 81 is used to display one or more pages of menu selection interface and selection cursor to the operator, each page of menu selection interface has multiple menu options. The operation lever is supported on the housing in a rotatable and slidable manner.

[0029] like Figure 4 As shown, it shows a page of menu selection interface displayed on the display screen 81, in which there are five menu options: "Strong", "High Power", "Normal", "Soft" and "Accessories"; among them, the menu option corresponding to "Strong" is designated by the square-shaped selection cursor 810.

[0030] like Figure 5 As shown, another menu selection interface is shown on the display screen 81. The menu selection interface has six menu options, namely, "Mode", "Filter", "Language", "Service", "Default" and "Version". The menu option corresponding to "Mode" is designated by the selection cursor 810.

[0031] like Figure 6 As shown, it shows the display prompt interface displayed on the display screen 81, in which the display prompt interface displays the information "Strong, remaining time XX minutes".

[0032] The operating lever 83 is operably connected to the control device 9 and enables the operator to manipulate the selection cursor 810 on the menu selection interface displayed on the display screen 81 to move between multiple menu options corresponding to the corresponding menu selection interface and select any option menu.

[0033] like Figure 1 , 2 As shown, the operating lever 83 is arranged on the upper part of the handle 11. The operating lever 83 and the power start button 82 are both configured to satisfy the thumb operation of the operator holding the handle 11. This structural design allows the operator to complete the operation of the portable vacuum cleaner host 100 with one hand.

[0034] like Figure 7 , Figure 8 and Fig. 9 As shown, the operating lever 83 is a single component, which includes a base 830, an operating end 831 located at the rear side of the base 830, a first trigger end 832, a second trigger end 833 and a third trigger end 834 located at the front side of the base 830, and a pair of support shafts 835 located at the left and right sides of the base 830. The pair of support shafts 835 define a rotation axis X. In this example, the rotation axis X extends in the left-right direction.

[0035] like Fig.10 As shown, the handle 11 is provided with a pair of support guide grooves 111 which cooperate with the pair of support shafts 835 and allow the support shafts 835 to be supported therein in a rotatable and slidable manner. In this example, the longitudinal section of the support guide groove 111 is U-shaped; the pair of support shafts 835 can rotate upward or downward around the rotation axis X in the pair of support grooves 111, and can also slide forward or backward.

[0036] The operating end 831 of the operating lever 83 is located outside the handle 11 , and the first trigger end 832 , the second trigger end 833 , the third trigger end 834 and the support shaft 835 are located inside the handle 11 .

[0037] Continue as Fig.11 , Fig.12 and Fig.13 As shown, the control device 9 includes a control panel 91 and a first trigger element 92, a second trigger element 93 and a third trigger element 94 arranged on the control panel 91. When the first trigger element 91 is triggered, the target menu option designated by the selection cursor 810 in the display screen 81 is selected; for example, Figure 4 In the menu selection interface, the "high power" menu option is selected. When the second trigger element 93 or the third trigger element 94 is triggered, the selection cursor 810 moves between multiple menu options; for example, in Figure 4 In the menu selection interface, the selection cursor 810 can be moved up and down between the various menu options such as "Strong", "High Power" and "Normal" in the menu selection interface.

[0038] The first trigger element 92 is arranged on the sliding path of the operating lever 8, and the second trigger element 93 and the third trigger element 94 are arranged on the rotation path of the operating lever 8. The first trigger end 832, the second trigger end 833 and the third trigger end 834 are respectively opposite to the first trigger element 92, the second trigger element 93 and the third trigger element 94 and are used to trigger the first trigger element 92, the second trigger element 93 and the third trigger element 94.

[0039] In this example, the operating lever 83 has a forward sliding limit position along its sliding path, and the first trigger element 82 is located at the sliding limit position. The operating lever 83 has a pair of rotation limit positions that are upward and downward and away from each other along its rotation path, the second trigger element 93 is adjacent to the upward rotation limit position, and the third trigger element 84 is adjacent to the downward rotation limit position.

[0040] An elastic washer 101 is disposed between the operating lever 83 and the control panel 9, and the first trigger end 831 passes through the elastic washer 101. The elastic washer 101 can help the operating lever 83 to remain in the initial position when no external force is applied; thus, after the operating lever 83 triggers the first trigger element 92, the second trigger element 93 or the third trigger element 94, the washer 101 can help it return to the initial position.

[0041] In the input device 8, the one or more pages of menu selection interfaces that can be displayed on the display screen 81 include a working mode selection interface, and the working mode selection interface has a plurality of different working mode options, such as Figure 4 As shown, the working mode options of "powerful", "high power", "normal", "gentle" and "accessory" are different. Under different working mode options, the working parameters of the vacuum cleaner, especially the power of the suction motor, are different. The control device 9 can control the vacuum cleaner to work in these different working modes respectively.

[0042] In some specific embodiments, among multiple different working mode options, one working mode option is preset as a default option, such as presetting the mode option corresponding to "high power" as the default option; this default option is automatically selected after the vacuum cleaner is turned on or the first trigger element 82 is triggered and maintained for a set time; for example: the operator slides the operating lever 83 forward (i.e., presses the operating lever 83 inward) and holds it for a few seconds, and the control device 9 automatically controls the vacuum cleaner to work according to the working mode corresponding to the default option.

[0043] In this example, the operator "presses the power start switch" means that the power of the entire machine is started; "presses the operating lever inward" means that the first trigger end 832 is selected to trigger the first trigger element 92; "rotates the operating lever upward" means that the second trigger end 833 is selected to trigger the second trigger element 93; "presses the operating lever downward" means that the third trigger end 834 is selected to trigger the third trigger element 94. Several examples are listed below to illustrate the information interaction process between the control device 9 and the input device 8: Example 1: Fig.14As shown, when the operator selects "press the power start switch", a preset menu selection interface is displayed on the display screen 81, and the menu options of the menu selection interface include: "strong", "high power", "normal", "gentle" and "accessories", wherein the selection cursor 810 initially falls on "high power"; at this time, if the operator selects "rotate the operating lever upward", the selection cursor 810 will move from "high power" to "strong", and at this time, if the operator selects "press the operating lever inward", the display screen 81 will jump to the information prompt interface of "strong remaining time XX minutes", and the operating device 9 will follow the "strong" The working mode controls the working of the vacuum cleaner; if the operator selects "press the operating lever inward", the display screen 81 jumps to the information prompt interface of "high power remaining time XX minutes", and the operating device 9 controls the working of the vacuum cleaner according to the "high power" working mode; or if the operator selects "rotate the operating lever downward", the selection cursor 810 moves from "high power" to "normal", and at this time, if the operator selects "press the operating lever inward", the display screen 81 jumps to the information prompt interface of "normal remaining time XX minutes", and the operating device 9 controls the working of the vacuum cleaner according to the "normal" working mode. Therefore, with the cooperation of the display screen and the operating lever in the input device 8, the operator can freely select the working mode of the vacuum cleaner for the control device 9.

[0044] Example 2: Fig.15 As shown, when the operator selects "Press the power start switch", a preset menu selection interface is displayed on the display screen 81. The menu options of the menu selection interface include: "Mode", "Filter", "Language", "Service", "Default" and "Version"; wherein the selection cursor 810 initially falls on the menu option of "Mode". At this time, if the operator chooses "press the operating lever inward", the display screen 81 will jump to a menu selection interface of another page, and the menu options of the menu selection interface on this page include: "strong", "high power", "normal", "gentle" and "accessories", among which the selection cursor 810 initially falls on "high power"; if the operator chooses to "press the operating lever inward" again, the display screen 81 will jump to the information prompt interface of "high power remaining time XX minutes", and the operating device 9 will control the vacuum cleaner to work according to the "high power" working mode; in this example 2, the operator can also choose "rotate the operating lever upward" or "rotate the operating lever downward" to move the selection cursor 810 between "mode", "filter element", "language", "service", "default" and "version" to select the target option of these menu options as needed; or move between "strong", "high power", "normal", "gentle" and "accessories" to select a preferred working mode for the control device 9.
