[0041] Example 1

[0042] See also Figure 1-6 The present invention provides a technical solution: a dust cup scraping and dust dumping linkage device of a vacuum cleaner, comprising:

[0043] A vacuum cleaner main unit 1, wherein a filter assembly 11 is arranged inside;

[0044] The scraper assembly 2 includes a mounting seat 21, a scraper ring 22 and a moving ring 23. The mounting seat 21 is fixedly mounted on the inner shell 12 of the vacuum cleaner main unit 1, the filter assembly 11 is fixedly mounted on the mounting seat 21, the scraper ring 22 is sleeved on the filter assembly 11, and a first transmission rod 231 is provided on the moving ring 23. The first transmission rod 231 passes through the mounting seat 21 and is connected to the scraper ring 22;

[0045] The ash dumping assembly 3 includes a sliding seat 31, a second transmission rod 32 and a lock 33. The sliding seat 31 is slidably connected to the inner shell 12, one end of the second transmission rod 32 is fixedly mounted on the sliding seat 31, and the lock 33 is rotatably mounted on the vacuum cleaner host 1. The end of the second transmission rod 32 contacts the lock 33. A hook portion 331 is provided at the bottom of the lock 33, and the hook portion 331 extends out of the shell of the vacuum cleaner host 1. A second spring 332 is provided on the back of the lock 33.

[0046] A dust cup cover 4 is rotatably mounted on the vacuum cleaner main unit 1;

[0047] A release handle 5, which is slidably connected to the vacuum cleaner main unit 1;

[0048] Among them, a connecting head is provided on the release handle 5, and the connecting head is passed through the shell of the vacuum cleaner main body 1. A first waist-shaped hole is provided on the shell of the vacuum cleaner main body 1. The connecting head is slidably connected in the first waist-shaped hole. The end of the connecting head is connected to the movable ring 23, and a snap-fit ​​groove 41 corresponding to the hook-shaped portion 331 is provided on the dust cup cover 4.

[0049] After the vacuum cleaner is used, the dust scraping component 2 and the dust dumping component 3 are linked to work by releasing the handle 5, and the dust is scraped first and then dumped. After the scraping is completed, the dust cup cover 4 is opened to dump the dust scraped off the surface of the filter component 11 together, thereby improving the cleaning effect and cleaning efficiency of the vacuum cleaner filter component 11.

[0050] The first transmission rod 231 is sleeved with a first spring 232, one end of the first spring 232 contacts the mounting seat 21, and the other end contacts the moving ring 23. The first spring 232 is compressed during the scraping process, so after the scraping is finished and the release handle 5 is released, it is easy to drive the moving ring 23 and the release handle 5 to reset.

[0051] Working principle: When the vacuum cleaner main unit 1 is used for cleaning, the release handle 5 is pushed, and the release handle 5 drives the moving ring 23 in the scraping assembly 2 to move, and the moving ring 23 pushes the scraping ring 22 to move linearly through the first transmission rod 231, and the scraping ring 22 scrapes the dust remaining on the surface of the filter assembly 11 to achieve scraping;

[0052] When the release handle 5 drives the movable ring 23 to move in a straight line and has not yet moved to the extreme position, the movable ring 23 contacts the sliding seat 31, thereby squeezing and driving the sliding seat 31 to slide along the inner shell 12. The sliding seat 31 then squeezes the upper end of the lock buckle 33 through the second transmission rod 32, causing the lock buckle 33 to rotate. As the release handle 5 moves to the extreme position, the lock buckle 33 rotates to the maximum angle. At this time, the hook-shaped portion 331 at the bottom of the lock buckle 33 retreats to release the lock on the dust cup cover 4, thereby opening the dust cup cover 4 and emptying the dust.

[0053] Example 2

[0054] This embodiment further provides the following improved technical solutions based on the above embodiments: a support block 121 is provided on the inner shell 12, and the sliding seat 31 is slidably connected to the support block 121. The support block 121 allows the sliding seat 31 to slide smoothly on the one hand, and prevents the sliding seat 31 from separating from the inner shell 12 on the other hand.

[0055] One end of the support block 121 is provided with a step surface 1211. The step surface 1211 can abut against the sliding seat 31 to limit the travel of the sliding seat 31, thereby effectively controlling the scraping travel and the moving distance of the release handle 5.

[0056] Example 3

[0057] This embodiment further provides the following improved technical solutions based on the above embodiments: a locking bolt 122 is provided on the support block 121, a second waist-shaped hole 311 is provided on the sliding seat 31, and the screw of the locking bolt 122 passes through the second waist-shaped hole 311 and is fixedly installed on the support block 121. The screw of the locking bolt 122 further limits the travel of the sliding seat 31 by sliding in the second waist-shaped hole 311, and the locking bolt 122 is used to further prevent the sliding seat 31 from being separated from the inner shell 12.

[0058] Example 4

[0059] This embodiment further provides the following improved technical solution based on the above embodiment: a pressing block 123 is further provided on the inner shell 12 , and the pressing block 123 contacts the surface of the second transmission rod 32 .

[0060] The three pressing blocks 123 arranged along a straight line on the inner shell 12 effectively control the smooth pushing of the second transmission rod 32 to prevent the second transmission rod 32 from swinging up and down.

[0061] Example 5

[0062] This embodiment further provides the following improved technical solutions based on the above embodiments: the second transmission rod 32 is in a "U" shape, and includes a contact portion 321 and transmission portions 322 symmetrically arranged at both ends of the contact portion 321, the contact portion 321 contacts the lock 33, and the transmission portion 322 is connected to the sliding seat 31. The second transmission rod 32 is designed as an integral part, so that both sides of the vacuum cleaner main unit 1 can be pushed synchronously, and the unlocking effect of the lock 33 can be effectively ensured.

[0063] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
