[0026] As attached Figure 1-7 As shown, this embodiment shows a vacuum cleaner and its one-button dust emptying structure, wherein the one-button dust emptying structure includes a dust cup 1, a driving unit 2 and a lower shell 3, the driving unit 2 is arranged at the rear end of the dust cup 1, the lower shell 3 is arranged below the dust cup 1, and a cup cover 4 is arranged at one end of the dust cup 1 away from the driving unit 2, and the upper end of the cup cover 4 is hinged to the dust cup 1.

[0027] Among them, a claw 5 is arranged at the lower end of the cup cover 4, and a block 6 is arranged at the bottom of the dust cup 1, and the claw 5 is engaged with the block 6. The cup cover 4 is engaged with the dust cup 1 through the cooperation of the claw 5 and the block 6.

[0028] In this embodiment, an unlocking assembly is disposed in the lower shell 3. When in use, the user can drive the clamping block 6 through the unlocking assembly to disengage the clamping block 6 from the clamping claw 5 so that the cup cover 4 is opened, thereby achieving the purpose of improving the dust cleaning efficiency.

[0029] Specifically, the unlocking assembly includes a pull ring 7, a connecting rod 8, a lifting assembly 9 and a flip cover 10. The pull ring 7 is fixed to the side of the driving part 2 away from the dust cup 1. One end of the connecting rod 8 is connected to the pull ring 7, and a slope is set on the top of the other end of the connecting rod 8. A slope is set at the bottom of the lifting assembly 9, and the slope of the connecting rod 8 matches the slope of the lifting assembly 9. The flip cover 10 is hinged to the bottom of the front end of the dust cup 1 and is located above the lifting assembly 9. The clamping block 6 is located at the bottom of the flip cover 10. When the lifting assembly 9 rises and drives the flip cover 10 to rise, the clamping block 6 can be disengaged from the clamping claw 5.

[0030] Among them, a torsion spring is provided at the hinge between the cup cover 4 and the dust cup 1, so that the cup cover 4 can always remain in a pop-up state under the action of the torsion spring, that is, after the claw 5 is separated from the block 6, the cup cover 4 can instantly pop open to dump the dust.

[0031] like Figure 5 As shown, the working principle of the unlocking assembly of this embodiment is: the user pulls the pull ring 7 to the left, driving the connecting rod 8 to move to the left, and the inclined surface of the connecting rod 8 moves to the left to push the inclined surface at the bottom of the lifting assembly 9 to rise, thereby pushing the lifting assembly 9 to rise, and the lifting assembly 9 pushes the flip cover 10 upward to move upward, driving the clamping block 6 to disengage from the clamping of the clamping claw 5. At this time, the cup cover 4 pops open under the action of the torsion spring, and the dust inside the dust cup 1 can be poured out through the opening of the dust cup 1.

[0032] Specifically, Figure 6 As shown, the lifting assembly 9 includes a top block 11, a connecting column 12 and a bottom block 13 with an inclined surface at the bottom, and the bottom block 13 cooperates with the connecting rod 8. A first spring 14 is arranged outside the connecting column 12, and the upper end of the first spring 14 abuts against the bottom of the top block 11, and the lower end of the first spring 14 abuts against the bottom block 13. When working, the bottom block 13 moves upward under the action of the connecting rod 8, and the bottom block 13 also drives the top block 11 to push the flip cover 10 upward, thereby disengaging the clamping block 6 from the clamping claw 5. In this embodiment, the horizontal movement of the connecting rod 8 is converted into the vertical movement of the flip cover 10 through the lifting assembly 9.

[0033] like Figure 4As shown, a flip cover box 15 is provided at the bottom of the front end of the dust cup 1, the bottom of the flip cover box 15 is provided with an opening, the flip cover 10 is hinged at the opening of the flip cover box 15, a second spring 16 is provided in the flip cover box 15, the upper end of the second spring 16 abuts against the top of the flip cover box 15, and the second spring 16 abuts against the flip cover 10. The above arrangement enables the block 6 to return to its original position under the action of the second spring 16 when it is not lifted by the lifting assembly 9.

[0034] Among them, a third spring 17 is arranged at one end of the connecting rod 8 close to the pull ring 7, a retaining ring 18 is arranged on the connecting rod 8, one end of the third spring 17 abuts against the retaining ring 18, and the other end of the third spring 17 abuts against the pull ring 7; a bolt connection is arranged between the pull ring 7 and the connecting rod 8. The above arrangement enables the pull ring 7 to return to its original position under the action of the third spring 17 when the user does not pull it.

[0035] The vacuum cleaner in this embodiment includes the above-mentioned one-button dust dumping structure, and an air intake pipe 19 is arranged in the lower shell 3, and the air intake pipe 19 is connected to the dust cup 1.

[0036] The working principle of the vacuum cleaner of this embodiment is as follows: the driving part 2 generates suction to suck external dust into the dust cup 1 through the air inlet pipe 19. After being filtered by the dust cup 1, the dust in the dust cup 1 is cleaned through a dust dumping structure to improve the cleaning efficiency.

[0037] At least two screw columns 20 are arranged on both sides of the air intake pipe 19, and the air intake pipe 19 is screwed to the lower housing 3; the connecting rod 8 is located on the screw columns 20 on one side. The advantage of such arrangement is that the screw columns 20 are used for both fixing and supporting the connecting rod 8.

[0038] A limiting member 21 is disposed on the top of the lower housing 3, and the connecting rod 8 is located between the screw column 20 and the limiting member 21. The limiting member 21 and the screw column 20 limit the displacement of the connecting rod 8 from above and below respectively.

[0039] The vacuum cleaner of this embodiment further includes a gripping portion 22 and a power supply portion 23 . The power supply portion 23 is disposed at the bottom of the lower shell 3 . One end of the gripping portion 22 is connected to the driving portion 2 , and the other end is connected to the lower shell 3 .

[0040] Specifically, the gripping portion 22 includes a gripping rod 24, the gripping rod 24 is tilted, and the driving portion 2 is parallel to the gripping rod 24. The tilting of the gripping rod 24 is ergonomic, and the driving portion 2 is parallel to the gripping rod 24 because the pull ring 7 is on the driving portion 2, which is convenient for the user to pull the pull ring 7 with the index finger, middle finger or ring finger.

[0041] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
