[0046] Beneficial effects:

[0047] 1. The automatic dust cup opening and emptying structure of the vacuum cleaner of the present invention is realized by arranging an unlocking member on the air duct assembly of the vacuum cleaner base station, so that when the vacuum cleaner sub-unit assembly is placed on the vacuum cleaner base station, the unlocking member can link the lock pressing block to disengage from the dust cup lock, so that the locking state of the dust emptying cover on the dust cup is released; then the lifting push rod is driven to extend its output shaft through the through hole on the dust cover plate and lift the lifting block, so that the dust emptying cover rotates and the inner cavity of the dust cup assembly is opened; cooperate with the motor and fan inside the base station or the vacuum cleaner The machine is running to completely discharge the dust and hair in the dust cup assembly; after the ash is discharged, the lifting push rod is driven to reset, and the ash discharge cover elastically returns to close, preventing the dust and dirt poured into the vacuum cleaner base station from being raised again and contaminating the inner cavity of the dust cup assembly, thereby improving the efficiency of ash discharge and cleaning, and further improving the cleanliness of the dust cup of the vacuum cleaner; when the vacuum cleaner is used again, it is directly taken out of the vacuum cleaner base station, and the dust cup lock is disengaged from the unlocking part, and it can be elastically reset, so that the ash discharge cover returns to a tightly locked state again, improving the sealing of the dust cup. This design allows the vacuum cleaner to be docked with the base station. After the two are tightly docked, the ash discharge cover is unlocked, opened, emptied, closed, and locked. The vacuum cleaner is taken out and continued to be used in this process, realizing fully automatic cleaning of the dust cup, isolating the hair and dust and other dirt inside the dust cup from the outside world, preventing dust and hair from being scattered, ensuring efficient and clean cleaning of the dust cup, and improving the user experience.

[0048] 2. Through the unlocking structure design of the locking block and the unlocking piece on the dust cup assembly and the air duct tube assembly, when in use, after the dust cup assembly and the air duct tube assembly are docked and sealed, the vacuum cleaner continues to be pressed into the base station, and the unlocking piece is inserted into the wedge-shaped slot. Guided by the wedge-shaped structure, the locking block moves back to the dust cup lock, thereby realizing efficient unlocking of the dust dumping cover, ensuring that the dirt in the inner cavity of the vacuum cleaner and the base station is isolated from the external environment, while ensuring the opening and closing efficiency of the dust dumping cover.

[0049] 3. The male and female plug components are set and electrically connected with the lifting push rod, which is designed to link the process of docking the vacuum cleaner with the base station and the process of opening the ash dump cover driven by the lifting push rod. After the vacuum cleaner is inserted into the base station, the male plug component is docked with the female plug component, and the lifting push rod can be operated. The output shaft pushes the ash dump cover to rotate and open it, thereby improving the cleaning efficiency of the dirt in the dust cup component. The three are associated with the clock module in the base station, so that the lifting push rod is lifted, the ash dump cover is opened, and the motor fan runs to dump the ash for a certain period of time. After that, the power will be cut off and the structure will be reset to ensure the best dust cup cleaning effect while reducing energy consumption and realizing efficient automatic ash dumping function.

[0069] Example 1:

[0070] See also Figure 1-7 The utility model provides a technical solution: a structure for automatically opening the dust cup of a vacuum cleaner and emptying the dust when connected to a base station, comprising:

[0071] The vacuum cleaner sub-unit assembly 1 is provided with a dust cover 11, and the dust cover 11 is provided with a through hole 111;

[0072] The dust cup assembly 2 is assembled on the vacuum cleaner sub-unit assembly 1, and a dust dump cover 20 is elastically hinged on the bottom of the dust cup assembly 2 near the side of the vacuum cleaner sub-unit assembly 1;

[0073] A dust cup lock 201 is provided on the side edge of the ash dump cover 20, and a lock pressing block 24 corresponding to the dust cup lock 201 is elastically slidably provided on the dust cup assembly 2;

[0074] The ash dumping cover 20 has a lifting block 202 extending toward the through hole 111;

[0075] The air duct assembly 3 is provided on the vacuum cleaner base station, and is provided with an air duct body 31 , the inner cavity of the air duct body 31 being connected to the ash dumping cover 20 ;

[0076] The air duct assembly 3 is provided with an unlocking member 32 on the side of the air duct body 31 , and the unlocking member 32 is correspondingly associated with the locking pressing block 24 ;

[0077] The lifting push rod 4 is assembled in the mounting housing 33 on the air duct assembly 3, and its output end passes through the air duct assembly 3 and corresponds to the through hole 111. The dust cover 11 is provided, in addition to being used to guide the telescopic output shaft of the lifting push rod 4, and can also block the dust and hair discharged from the dust cup assembly 2 when the dust cover 20 is flipped open, preventing them from being lifted up and entering the vacuum cleaner sub-unit assembly 1, thereby achieving the full collection of hair, dust and dirt inside the dust cup assembly 2, ensuring the cleanliness of the vacuum cleaner, reducing the frequency of cleaning, and making it more convenient to use.

[0078] When the dust cup is in the air, the dust is discharged from the dust cup assembly and the dust is discharged to the dust collector, thereby improving the cleaning efficiency and the cleanliness of the dust cup. When the dust collector is used again, it is directly taken out of the dust collector base station, and the dust cup lock is disengaged from the unlocking piece, and the dust cup can be restored to the tightly locked state by elastic reset, thereby improving the sealing of the dust cup. This design enables the vacuum cleaner to be docked with the base station. After the two are tightly docked, the dust emptying cover is unlocked, opened, emptied, closed, and locked. The vacuum cleaner is taken out and continued to be used in the same process, achieving fully automatic cleaning of the hair, dust and other dirt inside the dust cup isolated from the outside world, preventing dust and hair from being scattered, ensuring efficient and tidy cleaning of the dust cup, and improving user experience.

[0079] The ash dumping cover 20 is provided with a plurality of hinged sleeves 203 on one side close to the vacuum cleaner sub-unit assembly 1, and a rotating shaft 204 is passed through the hinged sleeve 203; compared with the hinged design of two hinged sleeves corresponding to one rotating shaft in the conventional hinged structure, this embodiment reduces the arrangement interval of the hinged sleeve 203 to avoid the problems of the rotating shaft and the rotation axis of the two rotating parts on both sides of the hinged structure being offset and the rotating parts shaking when rotating in use. This design is used on the dust cup assembly 2 and the ash dumping cover 20, and can realize the stable opening and closing of the ash dumping cover 20, thereby ensuring that the internal dirt is guided and discharged in an orderly manner, and avoiding it from being embedded in the gap at the connection between the two, thereby ensuring the stability of the structural activity and the high neatness of use.

[0080] The end of the rotating shaft 204 is rotatably arranged on the dust cup assembly 2, and a rotating shaft torsion spring 205 is also sleeved on the rotating shaft 204. The middle part of the V-shaped rotating shaft torsion spring 205 abuts against the dust cup assembly 2, and the end thereof is positioned and abutted against the ash pouring cover 20. The V-shaped rotating shaft torsion spring 205 performs stable elastic pre-tightening on the ash pouring cover 20 and the dust cup assembly 2, ensuring that the ash pouring cover 20 is stable in flipping and opening and closing, quickly elastically resets after pouring ash, and is tightly closed with the dust cup assembly 2, achieving convenient use;

[0081] The dust cover 11, lifting block 202, and lifting push rod 4 are respectively arranged on the sides of the vacuum cleaner sub-unit assembly 1, the dust dumping cover 20, and the air duct pipe assembly 3, so as to facilitate the reasonable layout of the above-mentioned vacuum cleaner components and the stable docking of the vacuum cleaner sub-unit assembly 1, the dust cup assembly 2 and the air duct pipe assembly 3 and the lifting push rod 4 of the vacuum cleaner base station.

[0082] A dust collecting chamber 21 is provided inside the dust cup assembly 2. The bottom of the dust collecting chamber 21 is enclosed by a mounting frame 22 and is extended to have an ash discharge port 23.

[0083] The ash dumping cover 20 is provided with a first sealing ring 206 at the joint with the ash dumping port 23 to further ensure the tightness of the ash dumping cover 20 and the dust cup assembly 2;

[0084] The mounting frame 22 is provided with several collars 221 on the side of the ash discharge port 23, and the rotating shaft 204 is passed through the collar 221. Through the hinged structure design of multiple hinged sleeves 203, collars 221 and rotating shaft 204, the rotating parts on both sides of the hinged structure can be further avoided from the deviation of the rotating shaft and the rotation axis of the two when rotating and using, and the problem of shaking of the rotating parts can be further avoided, and the rotation and opening and closing of the ash discharge cover 20 can be made more stable, so that the dirt inside the dust cup assembly 2 can be guided and discharged in an orderly manner, and it can be avoided that the dirt is embedded in the gap between the two, thereby ensuring the stability of the structural activity and the high neatness of use.

[0085] A second sealing ring 311 is provided at the joint between the top edge of the air duct body 31 and the bottom of the dust cup assembly 2 to further improve the tightness of the connection between the vacuum cleaner and the base station and prevent the contents of the two from overflowing;

[0086] The side of the jacket 34 is also provided with a second guide groove 341. The air collecting pipe assembly 12 on the vacuum cleaner sub-unit assembly 1 is inserted into the jacket 34, and the guide block 121 on its side is inserted and positioned in the second inverted cone-shaped guide groove 341. This design increases the complexity of the docking structure, area, and positioning dimensions of the vacuum cleaner and the base station. The guide structure also reduces the difficulty of docking and positioning between the two, significantly improving the positioning stability of the two. This prevents the two from becoming loose due to vibration generated by the operation of internal electrical components or external conduction during dust removal. This further improves the tightness of the docking and the degree of isolation between the internal cavities of the two and the external environment during the dust removal process, achieving a neat cleaning of the dust cup.

[0087] The working principle of the automatic dust cup opening and dust emptying structure of the vacuum cleaner when connected to a base station in this embodiment includes:

[0088] After using the vacuum cleaner, when it is necessary to clean and discharge the dust, hair and other dirt in the dust cup, align the air collecting pipe assembly 12 of the vacuum cleaner sub-assembly 1 with the jacket 34, align the bottom of the dust cup assembly 2 and the dust discharge cover 20 with the inner cavity of the air duct body 31, and directly insert and place the vacuum cleaner on the vacuum cleaner base station. The above-mentioned multi-dimensional positioning structure can achieve stable positioning of the two.

[0089] After the vacuum cleaner is docked with the base station, the unlocking member 32 can be linked with the lock pressing block 24 to disengage the dust cup lock 201, so that the locking state of the dust cover 20 on the dust cup assembly 2 is released; then the lifting push rod 4 is driven to extend its output shaft through the through hole 111 on the dust cover plate 11, and lift the lifting block 202, so that the dust cover 20 rotates and the inner cavity of the dust cup assembly 2 is opened; in conjunction with the operation of the motor and fan inside the base station or the vacuum cleaner, the dust and hair in the dust cup assembly 2 are completely discharged;

[0090] After the ash is poured out, the lifting push rod 4 is driven to reset, and the ash pouring cover 20 is elastically reset and closed, so as to prevent the dust and dirt poured into the vacuum cleaner base station from being raised again and contaminating the inner cavity of the dust cup assembly 2, thereby improving the ash pouring and cleaning efficiency and further improving the cleanliness of the dust cup of the vacuum cleaner;

[0091] When the vacuum cleaner is ready for use again, simply remove it from the base station. The dust cup lock 201 disengages the unlocking member 32, allowing it to elastically reset, allowing the dust cover 20 to return to a tightly locked state, improving the dust cup's tightness. This design allows the vacuum cleaner to be docked with the base station. After the two are tightly docked, the dust cover 20 is unlocked, opened, emptied, closed, and locked. The vacuum cleaner is then removed and used again, performing the same process. This fully automatic cleaning isolates dirt such as hair and dust inside the dust cup from the outside world, preventing dust and hair from being scattered, ensuring efficient and neat dust cup cleaning, and improving the user experience.

[0092] Example 2:

The side of the lock buckle pressure block 24 is slidably provided on the guide bars 251, and a pressure block spring 252 is provided between the lock buckle pressure block 24 and the inner side wall of the guide frame 25;

[0094] The dust cup lock buckle 201 is laterally slidably arranged in the groove of the ash pouring cover 20 , and a lock spring is arranged between the inner wall of the ash pouring cover 20 and the dust cup lock buckle 201 .

[0095] The working principle of the automatic opening and dust emptying structure of the dust cup of a vacuum cleaner when connected to a base station in this embodiment includes: the above-mentioned locking structure is elastically and slidably connected to the corresponding vacuum cleaner component through the locking block 24 and the dust cup lock 201, so that the locking structure can buffer the collision impact of the locking block 24 and the dust cup lock 201 during the unlocking and locking cycle, thereby reducing usage noise and structural quality damage and improving service life.

[0096] Example 3:

[0097] See also Figure 3 、 4 On the basis of the above-mentioned embodiment 1, preferably, a wedge-shaped slot 241 is provided at the bottom of the lock pressing block 24, and the wedge-shaped slot 241 is staggered with the unlocking member 32;

[0098] The unlocking member 32 is an inclined boss disposed at the bottom of the first guide groove 321 inside the air duct assembly 3 .

[0099] The working principle of the automatic dust cup opening and dust emptying structure of the vacuum cleaner when connected to the base station in this embodiment includes: in this embodiment, through the unlocking structure design of the locking block 24 and the unlocking piece 32 on the dust cup assembly 2 and the air duct tube assembly 3, when in use, after the dust cup assembly 2 and the air duct tube assembly 3 are docked and sealed, the vacuum cleaner continues to be pressed into the base station, and the unlocking piece 32 is inserted into the wedge-shaped slot 241. Guided by the wedge-shaped structure, the locking block 24 moves back to the dust cup lock 201, thereby realizing efficient unlocking of the dust emptying cover 20, ensuring that the dirt and contents in the inner cavity of the vacuum cleaner and the base station are isolated from the external environment, while ensuring the opening and closing efficiency of the dust emptying cover.

[0100] Example 4:

[0101] See also Figure 1-5 On the basis of the above embodiment 1, preferably, a jacket 34 is provided on one side of the air duct body 31;

[0104] The male plug assembly 13 and the female plug assembly 35 are also associated with the lifting push rod 4, and the lifting push rod 4 is an electromagnetic push rod.

[0105] The working principle of the automatic dust cup opening and dust emptying structure of the vacuum cleaner when connected to the base station in accordance with the present embodiment includes: the specific design in accordance with the present embodiment is designed through the setting of male and female plug components and the electrical connection with the lifting push rod for the linkage between the docking process of the vacuum cleaner and the base station and the process of the lifting push rod 4 driving the dust emptying cover 20 to open. After the vacuum cleaner is inserted into the base station, the male plug component 13 is docked with the female plug component 35, and the lifting push rod 4 can be operated, and the output shaft pushes the dust emptying cover 20 to rotate and open, thereby improving the cleaning efficiency of the dirt in the dust cup component 2.
