Abstract

A charging stand ( 100 ) for a vacuum cleaner ( 200 ) includes a body ( 1 ), a pedal ( 2 ) and a safety protection device ( 3 ). The pedal ( 2 ) is disposed to the body ( 1 ) and is pivotable between a first position and a second position. The safety protection device ( 3 ) is disposed to the body ( 1 ), normally cooperate with the pedal ( 2 ), and separate from cooperation with the pedal ( 2 ) to make the pedal ( 2 ) move from the first position to the second position when moved.

First claim

What is claimed is:

1 . A charging stand for a vacuum cleaner, comprising:
a body; a pedal, disposed to the body and pivotable between a first position and a second position; and a safety protection device, disposed to the body, normally cooperating with the pedal, and separating from cooperation with the pedal to make the pedal move from the first position to the second position when the safety protection device is moved.

2 . The charging stand according to claim 1 , wherein at least two safety protection devices are provided, the at least two safety protection devices are disposed to the body and spaced apart from one another, and the at least two safety protection devices separate from the cooperation with the pedal to make the pedal move from the first position to the second position when moved.

3 . The charging stand according to claim 1 , wherein the safety protection device comprises:
a safety protection member, disposed at a side of the pedal and having a cooperating groove for cooperating with an edge of the pedal; and a resetting member, disposed between the safety protection member and the body, and configured to normally push the safety protection member in a direction facing the center of the pedal.

4 . The charging stand according to claim 3 , wherein the safety protection member is pivotably connected to the body, and has a first end and a second end, the cooperating groove being formed in the second end of the safety protection member,
wherein the second end of the safety protection member moves towards a direction away from the center of the pedal when the first end of the safety protection member is moved, to make the edge of the pedal separate from cooperation with the cooperating groove.

5 . The charging stand according to claim 4 , wherein the first end of the safety protection member has a guide face for pressing the first end of the safety protection member.

6 . The charging stand according to claim 5 , wherein the guide face is configured to obliquely extend from the top down and towards the center of the pedal.

7 . The charging stand according to claim 4 , wherein the first end of the safety protection member stretches out from an internal side surface of the body when the pedal is located at the first position.

8 . The charging stand according to claim 3 , wherein the resetting member is a resilient sheet or a spring.

9 . The charging stand according to claim 1 , wherein two safety protection devices are provided and located at a left side and a right side of the body, respectively.

10 . The charging stand according to claim 1 , wherein the pedal is horizontally disposed when located at the first position.

11 . The charging stand according to claim 1 , wherein a represents a rotation angle of the pedal rotating from the first position to the second position, wherein a satisfies 0 degree <α≦60 degrees.

12 . The charging stand according to claim 11 , wherein a further satisfies 1 degree ≦α≦10 degrees.

13 . The charging stand according to claim 1 , wherein the body has an open top, 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 1 , wherein a blade is disposed within the body, and the pedal has an opening formed in a position corresponding to the blade;
when the pedal is located at the second position, the blade stretches out from the opening to cut off hairs on a brush roll in the vacuum cleaner placed on the pedal, and the blade is located under the opening when the pedal is located at the first position.

15 . The charging stand according to claim 14 , further comprising:
a microswitch, disposed within the body, and triggered when the pedal is located at the second position to make the charging stand stop charging and the brush roll rotate.

16 . The charging stand according to claim 14 , wherein the blade extends in a curve way along a length direction of the blade.

17 . The charging stand according to claim 14 , 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 to the base, wherein the blade is disposed on the blade holder, and
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 a receiving groove used for receiving the elastic member is formed in the base when the elastic member is disposed between the blade holder and the base.

20 . The charging stand according to claim 19 , wherein an upper surface of the elastic member is higher than an upper surface of the base.

21 . The charging stand according to claim 14 , wherein the pedal is provided with a baffle sheet, and the opening is formed in the baffle sheet.

22 . The charging stand according to claim 21 , wherein the baffle sheet is horizontally disposed.

23 . The charging stand according to claim 21 , wherein a clearance groove is formed in a lower surface of a portion, close to the opening, of the baffle sheet.

24 . The charging stand according to claim 23 , wherein an internal wall of the clearance groove is configured to have a distance from an upper surface of the baffle sheet decreased gradually in a direction facing the opening.

25 . The charging stand according to claim 1 , wherein the pedal has a first end and a second end, and the first end of the pedal is pivotably connected to the body by a pivot;
an elastic resetting member is disposed between the second end of the pedal and the body, and configured to normally push the pedal in a direction facing the first position.

26 . The charging stand according to claim 25 , wherein a limiting member is provided at a side, close to the second end of the pedal, of the body, and the limiting member is located at a side, away from the elastic resetting member, of the pedal.
