Description

Vacuum cleaner base station

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on March 29, 2024, with application number 202410377104.8 and application name “Vacuum Cleaner Base Station”, the entire contents of which are incorporated into this application by reference. Technical Field

[0002] The present application relates to the technical field of cleaning equipment, and in particular to a vacuum cleaner base station. Background Art

[0003] After using a portable vacuum cleaner, users often need to manually clean the dust cup, significantly reducing its convenience. Currently, portable vacuum cleaners are available on the market with a base station. This base station comes with a built-in vacuum system; after use, the portable vacuum cleaner can be stored at the base station, where it automatically cleans the dust cup.

[0004] Common portable vacuum cleaners are attached to the base station via a clamping arm or magnetic connection. While this solution is simple and convenient for users to place and remove the portable vacuum cleaner, if the base station is hit by an external force or the user accidentally picks it up while cleaning the portable vacuum cleaner, it can separate from the dust cup, potentially allowing the dust in the portable vacuum cleaner's dust cup to spread externally.

[0043] In order to explain the technical content, structural features, achieved objectives and effects of the invention in detail, the technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0044] In the following, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of the features.

[0045] In this application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0046] Referring to FIG1 , a vacuum cleaner base station 100 is shown. The vacuum cleaner base station 100 can dock a portable vacuum cleaner 900 or a vacuum cleaner similar to the portable vacuum cleaner 900 . During docking, the vacuum cleaner base station 100 can clean dust stored in the portable vacuum cleaner 900 and recharge the portable vacuum cleaner 900 .

[0047] A typical portable vacuum cleaner 900 includes a body 91, a rechargeable battery pack 92, and a dust cup 93 for storing garbage. The bottom of the dust cup 93 is provided with a dust cup cover 94 that can be opened and closed. One end of the dust cup cover 94 is pivotally connected to one side of the bottom of the dust cup 93. A torsion spring 98 (see Figure 12) is provided at the pivotal connection between the dust cup cover 94 and the dust cup 93. A locking hook 99 (see Figure 12) supported by a spring (not shown) is provided on the other side of the bottom of the dust cup 93, and the other end of the dust cup cover 94 is configured to engage with the locking hook 99. When the dust cup cover 94 is in the closed position, the other end of the dust cup cover 94 is fixedly engaged with the locking hook 99; when the locking hook 99 is triggered by an external force, the other end of the dust cup cover 94 separates from the locking hook 99, and the dust cup cover 94 will open from the bottom of the dust cup 93 under the action of the torsion spring 98, and the internal space of the dust cup 93 is connected to the outside world.

[0048] The vacuum cleaner base station 100 includes a housing 1 forming the outer contour of the vacuum cleaner base station 100. A base 11 for carrying the portable vacuum cleaner 900 is provided on the upper portion of the housing 1. A dust collecting device 4 is provided inside the housing 1.

[0049] The base 11 is provided with a first recess 12 for supporting the dust cup 93 from below, a second recess 13 for receiving the battery pack 92, and a pair of clamping walls 14 for clamping the portable vacuum cleaner 900. The second recess 13 is located above the first recess 12. The pair of clamping walls 14 are arranged on the left and right sides of the second recess 13. The second recess 13 is provided with a charging port 15 for charging the rechargeable battery pack 92.

[0050] 2 , a dust collection device 4 is configured to remove debris from the dust cup 93 of a portable vacuum cleaner 900. The dust collection device 4 includes a suction channel 41, a dust bag 42 made of air-permeable material capable of trapping debris, and a vacuum motor 43. The suction channel 41 has an upper inlet 411 for connecting to the dust cup 93 and a lower outlet 412 for connecting to the dust bag 42. The vacuum motor 43 provides suction that draws external debris (e.g., debris from the dust cup 93) along with air into the suction channel 41 and into the dust bag 42.

[0051] In order to automatically clean the dust cup 93 of the portable vacuum cleaner 900 parked at the vacuum cleaner base station 100 , the vacuum cleaner base station 100 further includes a cover opening mechanism 3 , a cover closing mechanism 5 and a control device 7 for controlling the vacuum cleaner base station 100 .

[0052] When the portable vacuum cleaner 900 is docked at the vacuum cleaner base station 100, the lid opening mechanism 3 can drive the dust cup cover 94 to open, and the lid closing mechanism 5 can drive the dust cup cover 94 to close. The control device 7 can control the vacuum cleaner base station 100 to execute a cleaning program for the portable vacuum cleaner 900. During this cleaning program, the control device 7 can control the lid opening mechanism 3, the lid closing mechanism 5, and the dust collection device 4. The control device 7 can execute the cleaning program when a cleaning switch (not shown) is activated, or after receiving an external start command. The control device 7 can also automatically initiate the cleaning program after determining that the requirements are met.

[0053] 5 , the cover opening mechanism 3 includes a moving block 32 for opening the lock hook 99 and a cover opening motor 31 for driving the moving block 32 to move. In this example, the cover opening motor 31 can drive the moving block 32 to move in the up and down directions.

[0054] 7 and 8, the cover closing mechanism 5 includes a push rod assembly 51, a cover closing motor 52 that is driven by the push rod assembly 51, and a mounting base 53. The push rod assembly 51 and the cover closing motor 52 are mounted on the mounting base 53, and the mounting base 53 can be fixedly mounted on the housing 1 of the vacuum cleaner base station 100.

[0055] In some embodiments of the present application, the mounting base 53 includes a box portion 531 on the left and a slide rail portion 532 on the right. The lid closing motor 52 is fixedly mounted behind the box portion 531. The push rod assembly 51 is mounted on the slide rail portion 532. Multiple mounting holes 533 are provided on both sides of the slide rail portion 532. The mounting base 53 can be fixedly mounted within the housing 1 through the mounting holes 533 and fasteners (not shown).

[0056] 5 and 6 , the push rod assembly 51 includes a push rod 511. The push rod 511 is configured to be able to move along a pushing direction X. The pushing direction X is configured to be at an angle of 0-90 degrees to the front-to-back direction; if selected, 60°, 45°, etc. In some embodiments of the present application, the suction channel 41 is provided with an opening 413 (see FIG6 ). The opening 413 is located below the slide rail portion 532 and is connected to the lower portion of the slide rail portion 532. When the push rod 511 moves downward along the pushing direction X, the push rod 511 can pass through the opening 413.

[0057] In some embodiments of the present application, the push rod assembly 51 further includes a wheel assembly 512. The wheel assembly 512 is mounted on the lower end of the push rod 511. The wheel assembly 512 includes a wheel bracket 5121 and a wheel 5122.

[0058] The lower portion of the push rod 511 defines a receiving chamber 5114. A limiting sliding groove 5115 is provided on the wall of the receiving chamber 5114 for limiting the movement range of the wheel assembly 512 in the pushing direction X.

[0059] The wheel bracket 5121 has an upper end and a lower end that are away from each other along the pushing direction X. The wheel 5122 of the wheel assembly 512 is rotatably mounted on the lower end of the wheel bracket 5121. The upper end of the wheel bracket 5121 is arranged inside the storage cavity 5114. A pin 5123 that can cooperate with the limiting slide 5115 is provided at the upper end of the wheel bracket 5121. A movement constraint mechanism is formed by the cooperation between the pin 5123 and the limiting slide 5115. The movement constraint mechanism can effectively limit the range of motion of the wheel assembly 512 relative to the push rod, that is, the movement distance of the wheel assembly 512 relative to the push rod 511 in the pushing direction X does not exceed the size of the limiting slide 5115. In other embodiments, other movement constraint mechanisms such as blocks can be used instead of slides and pins to achieve similar effects.

[0060] A buffer spring 55 is provided inside the storage chamber 5114. The buffer spring 55 is arranged at the upper end of the wheel bracket 5121 and abuts against the top wall of the storage chamber 5114. When the downward stroke of the push rod 511 along the pushing direction X is too long, the buffer spring 55 can be compressed, which can alleviate the excessive squeezing of the dust cup cover 94 by the wheel 5122. In other embodiments, similar effects can be achieved by replacing the buffer spring and wheel assembly with other structures of rubber pads. When the dust cup cover is strong enough, the push rod can also be directly abutted against the dust cup cover to reduce the manufacturing cost of the vacuum cleaner base station.

[0061] In some embodiments of the present application, a transmission assembly consisting of a gear 56 and a rack 57 is arranged between the lid closing motor 52 and the push rod assembly 51. The gear 56 and the rack 57 are meshed with each other. The gear 56 is transmission-connected to the output shaft (not shown) of the lid closing motor 52, and the rack 57 is fixed to the push rod 511; in this example, the rack 57 and the push rod 511 are constructed as the same component. In other embodiments, other transmission mechanisms such as screw rods, chains, and belts can be used to replace the transmission of the gear and rack. In some embodiments of the present application, the vacuum cleaner base station 100 also includes a locking mechanism 6. The locking mechanism 6 is constructed to be locked when the portable vacuum cleaner 900 is docked at the vacuum cleaner base station 100 and is cleaning the garbage in the dust cup 93, thereby preventing the portable vacuum cleaner 900 from detaching from the vacuum cleaner base station 100 during dust cleaning, eliminating the hidden danger of garbage in the dust cup 93 spreading to the outside.

[0062] 3 and 4 , in some embodiments of the present application, the locking mechanism 6 includes a locking block 61 disposed inside a clamping wall 14 .

[0063] The locking block 61 includes a transition body 612 and an abutting body 611. A transition spring 613 is provided between the abutting body 611 and the transition body 612. This spring 613 creates a variable-size operating gap 615 between the abutting body 611 and the transition body 612. A return spring 614 is also provided between the clamping wall 14 and the abutting body 611. This return spring 614 creates a variable-size operating gap 616 between the clamping wall 14 and the abutting body 611. The right portion of the abutting body 611 has a protrusion 6111. The clamping wall 14 is provided with a through-hole 141. The protrusion 6111 can be exposed through the through-hole 141.

[0064] When no external force is applied to the transition body 612, the locking block 61 is in the released position (see FIG13 ), and the portable vacuum cleaner 900 can be removed from the vacuum cleaner base station 100 by the user (not shown). Specifically, the transition spring 613 and the return spring 614 are in a free state. The operating gaps 615 and 616 are uncompressed. The protrusion 6111 of the abutting body 611 is retracted into the interior of the clamping wall 14.

[0065] When an external force acts on the transition body 612, the locking block 61 is moved from the released position to the locked position (see FIG. 15 ). In the locked position, the locking block 61 is able to lock the portable vacuum cleaner 900 to the vacuum cleaner base station 100 (not shown). As the locking block 61 moves from the released position to the locked position, the transition spring 613 and the return spring 614 are compressed, and the operating gaps 615 and 616 are compressed. The protrusion 6111 of the abutting body 611 extends from the opening 141 of the clamping wall 14, allowing the protrusion 6111 to abut against the portable vacuum cleaner 900.

[0066] In other embodiments, only the abutment body 611 and the return spring 614 may be retained. In this case, the external force directly acts on the abutment body to convert the locking block from the release position to the locking position.

[0067] In the technical solution of the present application, the locking mechanism 6 is arranged in a transmission manner with the lid closing mechanism 5, so that the lid closing motor 52 provides power to the locking block 61 to switch from the released position to the locked position. This can effectively reduce the number of motors, thereby reducing the manufacturing cost of the vacuum cleaner base station 100.

[0068] In order to realize the transmission setting relationship between the locking mechanism 6 and the cover closing mechanism 5, as shown in Figures 9 to 11, in some embodiments of the present application.

[0069] 9 , the push rod 511 is provided with a first inclined surface 5112 and a side surface 5113 . The side surface 5113 is located above the first inclined surface 5112 and is adjacent to the first inclined surface 5112 .

[0070] 3 , the base 11 is further provided with a first swinging member 62 pivotally connected to the base 11 via a rotating shaft 623, and a second swinging member 63 pivotally connected to the base 11 via a rotating shaft 631. The axis L1 of the rotating shaft 623 and the axis L2 of the rotating shaft 631 both extend in the vertical direction (see FIG. 9 ).

[0071] Continuing with Figure 9, the first swing member 62 includes two swing arms, one of which includes an abutting surface 621 and a second inclined surface 622 disposed above the abutting surface 621. The abutting surface 621 is adjacent to the second inclined surface 622. The second swing member 63 includes two swing arms, each of which abuts the first swing member 62 and the locking block 61, respectively.

[0072] The push rod 511 establishes a transmission relationship with the locking block 61 of the locking mechanism 6 via the first swing member 62 and the second swing member 63 .

[0073] In some embodiments of the present application, the lid closing motor 52 of the lid closing mechanism 5 can provide both power for moving the push rod 511 and power for moving the locking block 61. The lid closing motor 52 is configured to operate in a first stroke and a second stroke after the first stroke.

[0074] During the first stroke of the lid closing motor 52, the lid closing motor 52 drives the push rod 511 from the starting position (see FIG. 9 ) to the intermediate position (see FIG. 10 ). The first inclined surface 5112 of the push rod 511 continuously abuts the second inclined surface 622 of the first swinging member 62. The first inclined surface 5112 pushes the second inclined surface 622 rightward, thereby driving the first swinging member 62 to rotate clockwise about the axis L1 by a set angle from the first position (see FIG. 9 ) to the second position (see FIG. 10 ). The second swinging member 63 rotates counterclockwise about the axis L2. The rotation of the second swinging member 63 drives the locking block 61 to move. When the push rod 511 reaches the intermediate position, the side surface 5113 of the push rod 511 abuts the abutting surface of the first swinging member 62, causing the locking block 61 to shift from the released position to the locked position.

[0075] During the second stroke of the lid closing motor, the lid closing motor drives the push rod from the intermediate position to the end position (see FIG11 ). The side surface 5113 of the push rod 511 continuously abuts against the abutment surface 621 of the first swinging member 62. At this time, the first swinging member 62 remains stationary, and the locking block 61 remains in the locked position. The wheel assembly 512 abuts against the dust cup cover 94, thereby pushing the dust cup cover 94 closed (see FIG16 ).

[0076] In other embodiments, other transmission schemes may be used to transmit the power of the cover closing motor to the locking block, such as simultaneously meshing the gear with another rack, and having the rack replace the push rod to drive the locking block.

[0077] The following describes the process of the portable vacuum cleaner 900 docking at the vacuum cleaner base station 100 to perform dust cleaning work in conjunction with Figures 12 to 16:

[0078] The portable vacuum cleaner 900 is parked on the vacuum cleaner base station 100, with the center line 95 of the dust cup 93 horizontally arranged in the front-to-back direction. Referring to Figures 12 and 13, at this time, the push rod 511 is in the starting position. The locking block 61 is in the release position.

[0079] When the control device 7 is triggered to initiate the dust cleaning process, the cover-opening motor 31 activates, driving the movable block 32 to press the locking hook 99 upward, releasing the dust cup cover 94. Driven by the torsion spring 98, the dust cup cover 94 rotates into the interior of the suction channel 41 and covers the opening 413. This covering prevents debris from entering the installation position of the push rod 511 through the opening 413 of the suction channel 41 and interfering with its operation. At this point, the dust cup 93, the suction channel 41, and the dust bag 42 are connected in sequence.

[0080] The lid closing motor 52 then operates in its first stroke (see Figures 14 and 15 ), during which the push rod 511 is driven from its starting position to its intermediate position. During this movement, the push rod 511 transmits force via its two swinging members, thereby shifting the locking block 61 from its released position to its locked position. At this point, the portable vacuum cleaner 900 is locked to the vacuum cleaner base station 100 by the locking block 61.

[0081] After the portable vacuum cleaner 900 is locked to the vacuum cleaner base station 100, the control device 7 controls the vacuum motor 43 to start, and the vacuum cleaner base station 100 transfers the garbage in the dust cup 93 to the dust bag 42 through the suction channel 41 through the suction force generated by the vacuum motor 43.

[0082] After all the garbage in the dust cup 93 has been removed, the control device 7 controls the lid closing mechanism 3 to close the dust cup lid 94. Before closing the dust cup lid 94, the control device 7 needs to reset the movable block 32 of the lid opening mechanism 3 to prevent the movable block 32 from being in contact with the locking hook 99 when closing the dust cup lid 94, thereby preventing the dust cup lid 94 from being closed. The reset of the movable block 32 of the lid opening mechanism 3 can be performed before the vacuum motor 43 is started or after the vacuum motor 43 is turned off.

[0083] Referring to FIG16 , after ensuring that the movable block 32 of the lid opening mechanism 3 has returned to its original position, the lid closing motor 52 is restarted to operate in the second stroke. During this second stroke, the push rod 511 is pushed from the intermediate position to the final position. As the push rod 511 is pushed from the intermediate position to the final position, the side surface 5113 of the push rod 511 continues to abut against the abutment surface 621 of the first swinging member 62, and the two swinging members remain stationary, restricting the locking block 61 to the locked position. Simultaneously, the wheel 5122 continues to abut against the dust cup cover 94 until the dust cup cover 94 is closed again.

[0084] Afterward, the control device 7 controls the various motors to reset the relevant components. Specifically, the lid closing motor 52 reverses, causing the push rod 511 to retract from its end position to its starting position. The force transmitted by the push rod 511 to the locking block 61 disappears. Under the action of the transition spring 613 and the return spring 614, the protrusion 6111 retracts from the opening 141 to the inside of the clamping wall 14, and the locking block 61 returns to its released position. At this point, the portable vacuum cleaner 900 is no longer locked to the vacuum cleaner base station 100. The user can remove the portable vacuum cleaner 900 from the vacuum cleaner base station 100 at any time.

[0085] Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments. The above-mentioned embodiments and descriptions are only for explaining the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. The scope of protection claimed in the present application is defined by the attached claims, description and their equivalents.
