Vacuum cleaners, due to their ease of operation and ease of use, are increasingly becoming part of people's lives, becoming integral to homes and offices, and becoming a crucial and popular small appliance.

[0003] To further enhance the user experience, existing vacuum cleaners often include a dust collection station for use with the vacuum cleaner. The dust collection station can be used to store and clean the vacuum cleaner. When the user needs to clean the dust cup, they can place the vacuum cleaner in the dust collection station, which then opens the vacuum cleaner cover to empty the dust cup, thereby cleaning the vacuum cleaner.

[0004] Existing vacuum cleaners have the following problems: when installed on the dust collection station, the dust cup cover is opened before the dust cup is installed in place, causing the dust in the dust cup to leak out. Some dust will remain at the position where the dust collection station and the cover are connected, and the dust will also cover the cover. When the vacuum cleaner equipment is taken out of the dust collection station, the dust will be brought out to the external space, affecting the user experience. Utility Model Content

[0041] It should be noted that the concepts of "first" and "second" mentioned in this utility model are only used to distinguish devices, modules or units, and are not used to limit these devices, modules or units to be different devices, modules or units, nor are they used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0042] See also Figures 1 to 11The utility model provides a dust cup, a vacuum cleaner device 4 using the dust cup, a dust collecting station 3 coordinated with the vacuum cleaner device, and a cleaning system composed of the vacuum cleaner device 4 and the dust collecting station 3, wherein the dust discharge port 121 of the dust cup is normally closed after being unlocked and can be opened under the action of external force, thereby avoiding the situation in which the dust discharge port 121 is opened in advance during the installation or use of the dust cup, causing the garbage (such as dust) in the dust cup to leak out in advance, thereby improving the user experience.

[0043] Example 1

[0044] See also Figures 1 to 7 In this embodiment, the structure of the dust cup is mainly described.

[0045] The dust cup has a cup body 1 and a cup cover assembly 2 pivotally connected to the cup body 1. Preferably, the cup body 1 is generally cylindrical, including a circular bottom wall 12 and a peripheral side wall 11 surrounding the bottom wall 12. The bottom wall 12 is provided with the dust discharge port 121. The cup cover assembly 2 is provided at the bottom of the cup body 1, and includes a normally closed cover plate 21 covering the dust discharge port 121. The normally closed cover plate 21 covers the dust discharge port in a manner of having an open state for opening the dust discharge port and a closed state for closing the dust discharge port. The normally closed cover plate 21 also has locked and unlocked states when the dust discharge port is closed. The normally closed cover plate 21 remains closed in the unlocked state and is not affected by external suction force, and opens in the unlocked state and under the action of external suction force, so that the garbage in the cup body 1 can be discharged from the dust discharge port 121.

[0046] The normally closed cover 21 is pivotally connected to the cup body 1 via a rotating shaft 211. The cup cover assembly 2 includes a locking assembly 22 for locking the normally closed cover 21. The locking assembly 22 is used to keep the normally closed cover 21 in a locked state to prevent the normally closed cover 21 from automatically opening and causing garbage to leak out.

[0047] Please combine Figure 3 In one embodiment, a torsion spring is connected between the normally closed cover 21 and the cup body 1. The torsion spring is sleeved on the preset torsion spring mounting portion 212 of the normally closed cover, so that the normally closed cover is normally closed relative to the dust exhaust port 121 of the cup body 1. When the normally closed cover 21 is opened by the suction force, the torsion spring accumulates energy; when the external force is removed, the normally closed cover gradually closes on the dust exhaust port 121 under the torsion force of the torsion spring.

[0048] The suction force can be generated by the dust collection station 3, or by establishing an air duct connection between the dust collection station and the suction motor of the vacuum cleaner device, using the motor in the vacuum cleaner to provide negative pressure within the dust collection station, thereby generating a suction force. This means that the normally closed cover can be opened under the action of negative pressure. In this second method of generating suction force, the dust collection station does not need to be equipped with a motor, which reduces costs and can also reduce the size of the dust collection station.

[0049] In one embodiment, the torsion spring mounting portion 212 is a rotating shaft that pivotally connects the normally closed cover 21 to the cup body 1 .

[0050] In one embodiment, the locking assembly 22 includes a pressure plate assembly 221 and an elastic member. The pressure plate assembly 221 presses the normally closed cover 21 onto the cup body 1 under the action of the elastic member.

[0051] The pressure plate assembly 221 is arranged near the rotating shaft 211 between the normally closed cover 21 and the cup body 1, and the elastic member is preferably a compression spring 222, which is pressed between the cup body 1 and the pressure plate assembly 221, and can be compressed and stored when the pressure plate assembly 221 is forced to move in the direction away from the normally closed cover 21. After the external force on the pressure plate assembly 221 disappears, the potential energy is released to move the pressure plate assembly 221 in the direction close to the normally closed cover 21, pressing the normally closed cover 21 tightly against the dust exhaust port 121 of the cup body 1.

[0052] It is assumed that the vacuum cleaner device is placed on the dust collecting station 3 along a first direction (such as a vertical direction from top to bottom), and the movement direction of the pressure plate assembly 221 is perpendicular to the first direction, that is, the pressure plate assembly 221 slides in the horizontal direction.

[0053] From the above, it can be seen that in this embodiment, the dust exhaust port 121 is opened on the bottom wall 12 of the cup body 1, then the first direction is the horizontal direction, and the pressure plate assembly 221 slides horizontally along the axis perpendicular to the cup body 1, and the sliding direction of the pressure plate assembly 221 is parallel to the first direction and perpendicular to the axis of the cup body 1. The outer side of the pressure plate assembly 221 is provided with a first unlocking inclined surface 2213, which is used to be pressed by the unlocking contact of the dust collecting station 3 to push the pressure plate assembly 221 in a direction away from the normally closed cover 21 and separate from the normally closed cover 21, thereby unlocking the normally closed cover 21. Since the cup cover assembly 2 is arranged on the circular bottom wall, the length direction of the unlocking contact on the dust collecting station 3 is arranged parallel to the docking direction. Therefore, during the docking process between the dust cup and the dust collecting station 3, the first unlocking inclined surface 2213 guides the unlocking contact to press the pressure plate assembly 221, causing the pressure plate assembly 221 to slide vertically in the direction of docking with the dust collecting station 3, thereby completing the unlocking of the normally closed cover 21 during the docking process. In this way, the docking unlocking structure is optimized, making the entire docking process smoother and improving the user experience.

[0054] In addition, the movement direction of the pressing plate assembly 221 and the handle 41 of the vacuum cleaner device (see Figure 8 ) forms an angle with the extension axis of the handle, which is 80°-140°. While ensuring the comfort of holding the handle, the docking and unlocking structure is optimized, making the entire docking process smoother and improving the user experience.

[0055] See also Figure 2 The cup body 1 is provided with a sliding space 124, and the pressure plate assembly 221 is embedded in the sliding space 124 and can slide along the sliding space 124. Preferably, a limiting protrusion 125 is provided at one end of the sliding space 124 away from the rotating shaft 211, which is used to limit the sliding stroke of the pressure plate assembly 221. When the pressure plate assembly 221 slides into place, it is stopped by the limiting protrusion 125.

[0056] Please combine Figure 4 and Figure 5 A touch block 2212 is provided in the middle of the outer side of the pressure plate assembly 221. The touch block 2212 can be pressed by the corresponding unlocking contact on the dust collecting station 3 when the dust cup is installed on the dust collecting station 3, so that the pressure plate assembly 221 moves in a direction away from the normally closed cover 21, thereby releasing the lock of the normally closed cover 21 and allowing the normally closed cover 21 to be opened under the action of external force.

[0057] Among them, the touch-pressure block 2212 is provided with a first unlocking slope 2213, which is used to cooperate with the second unlocking slope on the unlocking contact, so that when the dust cup is placed from top to bottom on the docking part of the dust collection station 3, the pressure plate assembly 221 slides linearly in the direction away from the normally closed cover 21.

[0058] In addition, the outer wall of the normally closed cover 21 is provided with a give way groove 213 at a position corresponding to the pressure plate assembly 221. The give way groove 213 extends along the sliding direction of the pressure plate assembly 221. The pressure plate assembly 221 can be slidably inserted into the give way groove 213, and then pressed against the outer side of the normally closed cover 21, pressing the normally closed cover 21 tightly against the cup body 1, and locking the normally closed cover 21.

[0059] The pressing plate assembly 221 has a pressing end that can be slidably inserted into the clearance groove 213 to press on the side of the normally closed cover 21 facing away from the dust discharge port 121. The end of the pressing end 221 has a guiding slope for facilitating the insertion of the pressing end into the clearance groove 213 of the normally closed cover 21.

[0060] A spring mounting post 2214 is provided at one end of the pressure plate assembly 221 away from the pressing end, and one end of the compression spring 222 is sleeved on the spring mounting post 2214 .

[0061] The pressure plate assembly 221 is provided with a guide rail at one end away from the clamping end and facing away from the touch-pressure block 2212. A guide plate is provided in the sliding space. The guide plate is inserted into the guide rail and slides along the guide rail, thereby installing the pressure plate assembly 221 in the sliding space and guiding the sliding of the pressure plate assembly 221.

[0062] Preferably, the contact block 2212 does not protrude from the outline of the cup body 1 to avoid the contact block 2212 protruding from the cup body 1 and being triggered by mistake, causing the garbage in the dust cup to leak out.

[0063] The bottom end of the cup body 1 includes an outer peripheral wall and an inner peripheral wall. The normally closed cover plate 21 is arranged on the inner peripheral side, and the locking assembly 22 is arranged within the outline of the outer peripheral wall.

[0064] The cup body 1 is also provided with a decorative cover 122, and the cup body 1 is also provided with a decorative cover mounting structure. The decorative cover 122 is connected to the decorative cover mounting structure, for example, by screws, and is installed at the bottom of the cup body 1 to cover the locking assembly and its sliding space so that the dust cup has a better appearance.

[0065] A sealing member 123 is provided between the normally closed cover 21 and the dust exhaust port 121 to improve the sealing effect at the joint between the normally closed cover 21 and the dust exhaust port 121 .

[0066] Example 2

[0067] See also Figure 8 , and combined with Figures 1 to 7 In this embodiment, the vacuum cleaner device of the present invention includes a cleaning body 4 and the aforementioned dust cup. The cleaning body is used to generate suction, and the dust cup is used to collect the waste sucked in by the suction. A handle 41 is provided on the outside of the cleaning body 4 for the user to grasp. A first suction source, a suction motor, is provided within the cleaning body 4 to generate suction to draw waste into the dust cup. Since the vacuum cleaner device includes the aforementioned dust cup, it also has its beneficial effects, which will not be described in detail here.

[0068] When the locking assembly 22 is provided with a slidable pressing plate assembly 221 , the sliding direction of the pressing plate assembly 221 is perpendicular to the axis of the first suction source.

[0069] Example 3

[0070] See also Figure 9 , and combined with Figure 10 and Figure 11 The dust collecting station 3 of this embodiment is used to connect to the dust cup of the vacuum cleaner equipment, including at least part of the structure of the dust outlet, to transfer the dust in the dust cup to the dust collecting station 3.

[0071] The dust collection station 3 includes a docking part 31, a dust collecting chamber 32 and a second suction source 33. The dust cup is installed at the upper end of the docking part 31 when docked. The dust collecting chamber 32 is connected with the docking part 31 through an air flow channel. The docking part is connected with the dust discharge port 121 of the dust cup after the dust cup is docked and the normally closed cover 21 of the dust cup is opened. The second suction source 33 is used to generate a suction airflow in the airflow channel to suck open the normally closed cover 21 in the unlocked state through the suction airflow, and then transfer the garbage in the dust cup to the dust collecting chamber 32 through the dust discharge port 121.

[0072] Correspondingly, the unlocking contact 34 is provided at the position corresponding to the touch-pressure block 2212 of the docking portion 31 and the pressure plate assembly 221. The unlocking contact 34 can press against the touch-pressure block 2212 during the installation of the dust cup on the integrated station 3, thereby pushing the pressure plate assembly 221 to slide away from the normally closed cover 21, so that the pressure plate assembly 221 is separated from the normally closed cover 21, and the normally closed cover 21 is unlocked, so that the normally closed cover 21 can be opened under the action of the suction airflow, and the garbage in the dust cup can be sucked out of the dust exhaust port 121 into the dust collecting chamber 32 by the suction airflow of the second suction source 33.

[0073] Preferably, the movement direction of the pressing plate assembly 221 and the axis of the second suction source 33 are perpendicular to each other.

[0074] It is assumed that the vacuum cleaner device is placed on the dust collection station 3 along a first direction, and the movement direction of the pressure plate assembly 221 is perpendicular to the first direction, so as to ensure that during the placement of the vacuum cleaner device, the unlocking contact 34 is aligned with the contact block 2212 of the pressure plate assembly 221 and pushes the pressure plate assembly 221 along a preset trajectory to complete the unlocking of the normally closed cover 21.

[0075] Among them, the touch block 2212 and the unlocking contact 34 are matched through an inclined surface, the touch block 2212 is provided with a first unlocking inclined surface 2213, and the unlocking contact 34 is provided with a second unlocking inclined surface matched with the first unlocking inclined surface 2213. The bottom wall of the cup body is provided with an avoidance hole corresponding to the touch block, so that when the dust cup is placed from top to bottom on the docking part of the dust collection station 3, the unlocking contact 34 passes through the avoidance hole and hits the touch block 2212. Under the thrust of the unlocking contact 34, the touch block 2212 causes the pressure plate assembly 221 to slide linearly in a direction away from the normally closed cover 21 and separate from the normally closed cover 21, thereby unlocking the normally closed cover 21.

[0076] Example 4

[0077] See also Figure 10 and Figure 11The cleaning system of this embodiment is composed of the vacuum cleaner device of the second embodiment and the dust collection station 3 of the third embodiment. Therefore, it also has the beneficial effects of the aforementioned vacuum cleaner device and dust collection station 3. Specifically, the normally closed cover 21 can be unlocked while the vacuum cleaner device is placed in the dust collection station 3, thereby opening the normally closed cover 21 under the action of the suction force of the second suction source 33 to complete the transfer of garbage from the dust cup. In addition, the normally closed cover 21 does not automatically open after the locking assembly is unlocked. It must be opened under the action of the suction force. This prevents the dust discharge port 121 from opening prematurely during installation or use of the dust cup, which could cause dust in the dust cup to be prematurely discharged, thereby improving the user experience.
