[0002] An upright vacuum cleaner is a dust removal tool. Existing upright vacuum cleaners include a main unit assembly, which includes a suction motor and a dust and gas separation unit. The main unit assembly is raised and lowered above the main body, with a floor brush unit located at the bottom. When cleaning open spaces, the main unit is positioned close to the floor brush unit, lowering the center of gravity and making it easier to use. When cleaning closed spaces, the main unit is moved upward to allow the floor brush unit to reach the floor.

[0003] This type of host assembly has two positions in the longitudinal length direction of the main body. The main control board of the host assembly needs to maintain electrical connection with the upright vacuum cleaner body at both positions on the main body to achieve electrical connection between the first electrical component group in the host assembly and the second electrical component group on the main body, or the motor on the main body, to achieve signal transmission or electrical energy transmission.

[0052] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0053] This embodiment provides a cleaning device for floor cleaning. Figure 1 and Figure 2 As shown, the cleaning device includes: a body 100 and a main body assembly 300, and the main body assembly 300 is arranged on the body 100. The following will mainly describe the scenario in which the cleaning device is used as an upright vacuum cleaner.

[0054] In this embodiment, the main body 100 includes a main body 110, a floor brush unit 120 located at one end of the main body 110, and a handle 130 located at the other end of the main body 110. The main body 110 is a hollow rod with a dust collection channel formed therein (not shown). The end of the main body 110 closer to the user is defined as the proximal end, and the end of the main body 110 farther from the user is defined as the distal end. In other words, the handle 130 is located at the proximal end of the main body 110, and the floor brush unit 120 is located at the distal end of the main body 110.

[0055] Furthermore, a sliding frame 200 is slidably mounted on the main body 110, wherein the main unit assembly 300 is detachably mounted on the sliding frame 200. In this embodiment, the sliding frame 200 is provided with a driving mechanism 400, which is used to drive the sliding frame 200 to slide on the main body 110, thereby achieving the lifting movement of the sliding frame 200 on the main body 110. Driven by the sliding frame 200, the main unit assembly 300 can slide back and forth between a first position and a second position on the main body 110.

[0056] In other words, the main unit assembly 300 is mounted on the sliding frame 200 and, driven by the sliding movement of the sliding frame 200, reciprocates between a first position and a second position on the main body 110. The first and second positions represent the parking positions of the sliding frame 200 on the main body 110. The first position is near the distal end of the main body 110, while the second position is near the proximal end of the main body 110. In other words, the first position is a low position, while the second position is a high position.

[0057] The main unit assembly 300 has an installed state, mounted on the sliding frame 200, and a detached state, removed from the sliding frame 200. When the main unit assembly 300 is mounted on the sliding frame 200 (installed state), the main unit assembly 300 and the sliding frame 200 are driven by the drive mechanism 400 to slide on the main body 110. When the main unit assembly 300 is removed from the sliding frame 200 (detached state), the main unit assembly 300 can be used independently as a handheld vacuum cleaner.

[0058] In this embodiment, the drive mechanism 400 is a structure having a linear reciprocating motion function, wherein the drive mechanism 400 includes at least a drive motor 410. For example, the drive mechanism 400 may be a rack and pinion structure, a lead screw structure, or a linear module.

[0059] Preferably, see Figure 1 and Figure 4 As shown, when the drive mechanism 400 is a rack and pinion structure, the drive mechanism 400 includes a rack 420 disposed on the outer wall of the main body 110, a gear 430 meshing with the rack 420, and the aforementioned drive motor 410 disposed on the carriage 200. The gear 430 is rotatably disposed on the carriage 200 and is in transmission connection with the output shaft of the drive motor 410. When the drive motor 410 drives the gear 430 to rotate, the gear 430 drives the carriage 200 to move up and down on the rack 420, thereby enabling the carriage 200 to slide back and forth between a first position and a second position on the main body 110.

[0060] See also Figure 3 As shown, the floor brush unit 120 includes a dust suction port 121 connected to the dust suction channel, a floor brush 122 disposed near the dust suction port 121, and a floor brush motor 123 that drives the floor brush 122. The floor brush motor 123 is housed inside the floor brush unit 120. The floor brush 122 rotates under the drive of the floor brush motor 123. The floor brush 122 is used to lift dust attached to the surface to be cleaned during the rotation process.

[0061] In this example, see Figure 5 and Figure 6As shown, the main unit assembly 300 includes a housing 320, an air intake duct 310 disposed on the housing 320, a dust and air separation unit 321 disposed on the housing 320, a dust and air separation channel connected to the dust and air separation unit 321, a main motor 322, and a battery unit assembly 330. The air intake duct 310 is part of the housing 320, and the main unit assembly 300 is mounted on the sliding frame 200 via the air intake duct 310. The dust cup of the dust and air separation unit 321 is also part of the housing 320. The air intake duct 310 forms a dust and air separation channel, which is provided with an inlet. Alternatively, the air intake duct 310 is provided with both the dust and air separation channel and the inlet. The inlet allows dust and air to enter the dust and air separation channel, and the dust and air separation channel allows dust and air to enter the dust and air separation unit 321. The main motor 322 and the battery unit assembly 330 are disposed within the housing 320. The battery cell group 330 is electrically connected to the main motor 322 and the drive motor 410 for supplying power to the main motor 322 and the drive motor 410 .

[0062] In this embodiment, when the main unit component 300 is separated from the main body 110 (separated state), the main motor 322 is used to generate suction force in the dust and gas separation channel; when the main unit component 300 is installed on the main body 110 (installed state), the dust and gas separation channel of the main unit component 300 is connected to the dust suction channel in the main body 110, and the main motor 322 is used to generate suction force on the dust suction channel.

[0063] Furthermore, when the main unit assembly 300 is installed on the main body 110 (installed state), the inlet port on the air intake duct 310 communicates with the dust collection channel of the main body 110, and dust enters the dust and air separation channel through the dust collection port 121, the dust collection channel, and the inlet port. When the main unit assembly 300 is detached from the main body 110 (detached state), the inlet port communicates with the dust and air separation channel, and dust enters the dust and air separation channel through the inlet port on the air intake duct 310. During operation, when the brush 122 rotates, dust attached to the surface to be cleaned is lifted up, which helps the dust collection port 121 to draw the dust into the dust collection channel.

[0064] Preferably, see Figure 1 Combined with Figure 10 As shown, the aforementioned inlet openings include a first inlet opening 311 provided at the free end of the inlet pipe 310 and a second inlet opening 312 provided on the sidewall of the inlet pipe 310. In the installed state, the first inlet opening 311 is closed and the second inlet opening 312 is open, allowing dust and gas to enter the dust and gas separation passage through the dust suction port 121, the dust suction passage, and the second inlet opening 312. In the separated state, the first inlet opening 311 is open and the second inlet opening 312 is closed, allowing dust and gas to enter the dust and gas separation passage through the first inlet opening 311.

[0065] Specifically, the purpose of setting up the inlet including the first inlet 311 and the second inlet 312 is: if only the first inlet 311 is set, in the installed state, there are multiple corners on the flow path of the dust and gas from the dust suction channel into the dust and gas separation channel, and the dust and gas flow is not smooth; while in this embodiment, in the installed state, the dust and gas enter the dust and gas separation channel through the second inlet 312 on the side wall of the air inlet pipe 310, which effectively reduces the number of corners and improves the fluidity of the dust and gas.

[0066] In this embodiment, in one power supply mode, please continue to refer to Figure 5 As shown, the battery cell assembly 330 includes a first battery cell 331. The first battery cell 331 is electrically connected to the main motor 322 and the drive motor 410, and is used to power the main motor 322 and the drive motor 410. As a result, the carriage 200 does not need to have a separate power supply to power the drive motor 410, effectively simplifying the structure and achieving a simple and compact structure.

[0067] In this embodiment, in another power supply mode, please continue to refer to Figure 6 As shown, the battery cell group 330 includes a first battery cell 331, a second battery cell 332, and a third power supply unit (not shown). The first battery cell 331 is electrically connected to the main motor 322 for supplying power to the main motor 322. The second battery cell 332 is electrically connected to the drive motor 410 for supplying power to the drive motor 410.

[0068] The third power supply unit can be considered a charging power source, used to supply power to the battery unit connected thereto. Specifically, there are three situations: In the first situation, the first battery unit 331 is electrically connected to the third power supply unit, while the second battery unit 332 is not. In this situation, the first battery unit 331 and the second battery unit 332 are electrically connected, and the third power supply unit is used to supply power to the first battery unit 331, while the first battery unit 331 is used to supply power to the second battery unit 332.

[0069] In the second case, the third power supply unit is electrically connected to the first battery unit 331 and the second battery unit 332. In the above case, the third power supply unit is used to supply power to the first battery unit 331 and the second battery unit 332 respectively.

[0070] In the third case, the third power supply unit is electrically connected to the second battery unit 332 , and the third power supply unit is used to supply power to the second battery unit 332 . The second battery unit 332 is electrically connected to the drive motor 410 , and the second battery unit 332 is used to supply power to the drive motor 410 alone.

[0071] The third power supply unit may be an external power source or a wireless battery pack. In this embodiment, preferably, the first battery unit 331, the second battery unit 332, and the third power supply unit are all battery packs.

[0072] In this embodiment, regardless of the power supply method, the floor brush motor 123 can be powered by a separate battery unit. Alternatively, the floor brush motor 123 is electrically connected to the first battery unit 331, and the first battery unit 331 is electrically connected to the floor brush motor 123.

[0073] In this embodiment, the main body 100 is further provided with a first electrical component group, and the main body assembly 300 is further provided with a second electrical component group. The first electrical component group and the second electrical component group are used to control the working state of the cleaning device. The first electrical component group is provided on the handle 130 of the main body 110. Please continue to refer to Figure 5 and Figure 6 As shown, the second electrical component group includes a main control board 323 , which is disposed in the housing 320 and electrically connected to the main motor 322 , wherein the main control board 323 and the main motor 322 are electrically connected to the first battery unit 331 respectively.

[0074] In this example, see Figure 7 and Figure 16 As shown, the first electrical connection portion 115 and the second electrical connection portion 116 are respectively provided on the main body 110 corresponding to the first position and the second position, and the first electrical component group is electrically connected to the first electrical connection portion 115 and the second electrical connection portion 116. Figure 8 and Figure 15 As shown, a third electrical connection portion 250 is provided on the sliding frame 200 , and the second electrical component group is electrically connected to the third electrical connection portion 250 .

[0075] When the sliding frame 200 is in the first position, the third electrical connection portion 250 is electrically connected to the first electrical connection portion 115 by abutting force. When the sliding frame 200 is in the second position, the third electrical connection portion 250 is electrically connected to the second electrical connection portion 116 by abutting force.

[0076] Further, see Figure 9 and Figure 10 As shown, the sliding frame 200 is further provided with a fourth electrical connection portion 240, and the main assembly 300 is provided with a fifth electrical connection portion 314. The fourth electrical connection portion 240 is electrically connected to the third electrical connection portion 250. When the main assembly 300 is mounted on the sliding frame 200, the fourth electrical connection portion 240 and the fifth electrical connection portion 314 are electrically connected due to abutting force.

[0077] In this example, please continue to refer to Figure 8 and Figure 15As shown, the sliding frame 200 includes a support portion 210 for engaging with the air intake duct 310 of the main unit assembly 300, and a mounting portion 220 disposed on the support portion 210 for connecting to the main body 110. A third electrical connector 250 is disposed on the mounting portion 220, and a fourth electrical connector 240 is disposed on the support portion.

[0084] Preferably, see Figures 12 to 14 As shown, the fourth electrical connection portion 240 is a generally cylindrical plunger, and the fifth electrical connection portion 314 is a socket formed on the free end of the intake pipe 310. When the main unit assembly 300 is mounted on the sliding frame 200, the fourth electrical connection portion 240 is inserted into the socket, forming an electrical connection through abutment force.

[0085] Specifically, see Figure 12 As shown, the support portion 210 includes a longitudinal plate 212 extending along the longitudinal direction of the main body 110 and a transverse plate 211 extending perpendicularly to the longitudinal direction of the main body 110.

The longitudinal plate 212 extends in the same direction as the main body assembly 300 is mounted on the sliding frame 200. The fourth electrical connection portion 240 is disposed on the transverse plate 211. After the main body assembly 300 is mounted on the sliding frame 200, the free end of the air intake duct 310 abuts against the transverse plate 211. In other words, the transverse plate 211 at least partially bears the weight of the main body assembly 300, thereby supporting the main body assembly 300.

[0086] In this embodiment, the first electrical component group is a switch group provided on the handle 130. Figure 1As shown, the first electrical component group includes an operating switch 140, a gear shift switch 150, an up switch 160, and a down switch 170. The operating switch 140 is electrically connected to both the first electrical connection portion 115 and the second electrical connection portion 116; similarly, the gear shift switch 150 is electrically connected to both the first electrical connection portion 115 and the second electrical connection portion 116; the up switch 160 is electrically connected to both the first electrical connection portion 115 and the second electrical connection portion 116; and the down switch 170 is electrically connected to both the first electrical connection portion 115 and the second electrical connection portion 116.

[0087] After the host assembly 300 is installed on the sliding frame 200, the first electrical component group is electrically connected to the main control board 323 of the second electrical component group. The main control board 323 is electrically connected to the third electrical connection part 250 through the fifth electrical connection part 314 and the fourth electrical connection part 240. The third electrical connection part 250 is electrically connected to the first electrical connection part 115 or the second electrical connection part 116 according to the position of the sliding frame 200.

[0088] In this embodiment, the main control board 323 is used to synchronously control the main motor 322 and the floor brush motor 123 to turn on or off based on the signal from the operating switch 140. The gear shift switch 150 has at least two gear positions, and the main control board 323 is used to control the output power of the main motor 322 to increase or decrease based on the signal from the gear shift switch 150. The main control board 323 is used to control the drive motor 410 to rotate in the forward direction based on the signal from the up switch 160, thereby driving the sliding frame 200 and the main assembly 300 to move upward (from the first position to the second position). Similarly, the main control board 323 is used to control the drive motor 410 to rotate in the reverse direction based on the signal from the down switch 170, thereby driving the main assembly 300 to move downward (from the second position to the first position).

[0089] In this example, see Figure 5 and Figure 6 As shown, the second electrical component group also includes a host switch 341 on the host assembly 300. The host switch 341 is electrically connected to the main control board 323. The host switch 341 is located on the grip 340 of the host assembly 300, which is located on the outer wall of the housing 320. After the host assembly 300 is removed from the sliding frame 200 (in the detached state), the user can control the operating mode of the host assembly 300 using the host switch 341.

[0090] Specifically, when the main unit assembly 300 is separated from the sliding frame 200, the user triggers the main unit switch 341, and the main control board 323 controls the operating mode of the main motor 322. This operating mode can include turning the main motor 322 on or off, and can also include adjusting the speed of the main motor 322. As a result, the main unit assembly 300 can be used independently as a handheld vacuum cleaner.

[0091] To sum up, electrical connection is achieved between the third electrical connection part 250 and the first electrical connection part 115, between the third electrical connection part 250 and the second electrical connection part 116, and between the fourth electrical connection part 240 and the fifth electrical connection part 314 through abutment. Compared with the traditional line connection, the connection structure is effectively simplified, and it has the advantages of simple connection structure, stable and reliable connection, and beautiful appearance.

[0092] Obviously, the embodiments described above are only part of the embodiments of the present invention, rather than all of the embodiments.
