Abstract

A charging stand ( 100 ) for a vacuum cleaner ( 200 ) includes: a body ( 1 ); and a blade ( 4 ) vertically disposed on the body ( 1 ), in which the blade ( 4 ) extends curvedly along a length direction of the blade ( 4 ) and is configured to cut off hairs wound around a brushroll ( 201 ) of the vacuum cleaner ( 200 ).

First claim

What is claimed is:

1. A charging stand for a vacuum cleaner, comprising:
a body having a battery charger; and
a blade vertically disposed on the body, wherein the blade extends curvedly along a length direction of the blade and is configured to cut off hairs wound around a brushroll of the vacuum cleaner.

2. The charging stand according to claim 1 , wherein the blade extends in an arc or wavy manner along the length direction thereof.

3. The charging stand according to claim 1 , further comprising a pedal disposed on the body and pivotable between a first position and a second position.

4. The charging stand according to claim 3 , further comprising a safety protection device disposed on the body and normally engaged with the pedal, wherein when the safety protection device is toggled, the safety protection device is disengaged from the pedal to make the pedal move from the first position to the second position.

5. The charging stand according to claim 4 , wherein at least two safety protection devices are provided; the at least two safety protection devices are disposed on the body and spaced apart from each other; when the at least two safety protection devices are toggled, the at least two safety protection devices are disengaged from the pedal to make the pedal move from the first position to the second position.

6. The charging stand according to claim 4 , wherein each safety protection device comprises:
a safety protection member disposed at a side face of the pedal and defining an fitting groove in which an edge of the pedal is fitted; and
a resetting member disposed between the safety protection member and the body, and configured to normally push the safety protection member towards a center of the pedal.

7. The charging stand according to claim 6 , wherein the safety protection member is pivotably connected to the body;
the safety protection member has a first end and a second end, in which the fitting groove is defined in the second end of the safety protection member; when the first end of the safety protection member is toggled, the second end of the safety protection member moves away from the center of the pedal to disengage the edge of the pedal from the fitting groove.

8. The charging stand according to claim 7 , wherein the first end of the safety protection member has a guide surface configured to toggle the first end of the safety protection member.

9. The charging stand according to claim 8 , wherein the guide surface is constructed to extend obliquely towards the center of the pedal from up to down.

10. The charging stand according to claim 4 , wherein two safety protection devices are provided and located at a left side and a right side of the body respectively.

11. The charging stand according to claim 3 , wherein the pedal is disposed horizontally when in the first position.

12. The charging stand according to claim 3 , wherein a rotation angle of the pedal rotated from the first position to the second position is denoted as α, in which α satisfies 0°<α≤60°.

13. The charging stand according to claim 3 , wherein a top of the body is open, and the pedal is disposed within the body and spaced apart from a bottom wall of the body.

14. The charging stand according to claim 3 , wherein a lower surface of the pedal is provided with at least one reinforcing rib.

15. The charging stand according to claim 3 , wherein an opening is defined in the pedal and corresponds to a position of the blade;
when the pedal is in the second position, the blade extends out of the opening to cut off hairs around a brushroll of the vacuum cleaner placed on the pedal; when the pedal is in the first position, the blade is located below the opening.

16. The charging stand according to claim 15 , further comprising a microswitch disposed within the body, wherein when the pedal is in the second position, the microswitch is triggered to make the charging stand stop charging and rotate the brushroll.

17. The charging stand according to claim 1 , wherein the body has a base, and an elastic member is disposed between the blade and the base.

18. The charging stand according to claim 17 , further comprising a blade holder disposed on the base, wherein the blade is disposed on the blade holder; the elastic member is disposed between the blade and the blade holder and/or between the blade holder and the base.

19. The charging stand according to claim 18 , wherein when the elastic member is disposed between the blade holder and the base, an accommodating groove is defined in the base and configured to accommodate the elastic member.

20. The charging stand according to claim 3 , wherein the pedal has a first end and a second end, and the first end of the pedal is pivotably connected to the body through a pivot shaft;
an elastic resetting member is provided between the second end of the pedal and the body, and configured to normally push the pedal towards the first position.
