Abstract

Disclosed are a conversion member and an electric cleaner. The conversion member according to embodiments disclosed herein may be detachably coupled to a handle included in a main body and a pipe. Then, the main body may be connected to an intake port located at the lowest position, and the pipe may be connected to an extension handle, allowing the main body to be located at a lower position facing the intake port. Thus, the electric cleaner may have a low center of gravity. Further, when the conversion member is detached, the pipe may be located between the main body and the intake port to be connected to the main body and the intake port, respectively. Accordingly, the main body may be located at an upper position directed away from the intake port, allowing the electric cleaner to have a high center of gravity.

First claim

What is claimed is:

1. A conversion member for use with a cleaner, the conversion member comprising:
a collar configured to selectively receive an end of a pipe, wherein the pipe, when received in the collar, extends in a first direction from collar; and
a clamp connected to the collar in a second direction opposite to the first direction, wherein the clamp includes:
a first wall connected to the collar; and
at least one second wall rotatably connected to the first wall, wherein the first wall and the at least one second wall form a space for receiving the cleaner, wherein the at least one second wall includes a pair of second walls, wherein the conversion member further includes:
a latch rotatably provided at one of the pair of second walls; and a catch provided at another one of the pair of second walls,
wherein the latch and the catch are configured to be detachably coupled to each other, wherein a predetermined space is formed inside the latch, and the catch is detachably inserted into the space, wherein the at least one second wall includes a pair of second walls, wherein the clamp includes:
a first hinge rotatably coupled respectively to a one end of the first wall and a side end of one of the pair of second walls, and
a second hinge rotatably coupled respectively to another end of the first wall and a side end of another one of the pair of second walls, and
wherein a penetrating portion penetrates through one side of the pair of the second walls, respectively.

2. The conversion member of claim 1 , wherein each of the first wall and the at least one second wall includes a concave surface.

3. The conversion member of claim 1 , wherein the clamp includes a slip prevention layer provided on at least one inner surface of the at least one second wall.

4. The conversion member of claim 3 , wherein the clamp includes another slip prevention layer provided on an inner surface of the first wall.

5. The conversion member of claim 1 , wherein the clamp is configured to receive a handle of the cleaner.

6. The conversion member of claim 1 , wherein the at least one second wall includes a pair of second walls, and the clamp further includes a slot that extends through respective regions of the pair of second walls.

7. A vacuum cleaner, comprising:
a main body having a dust container;
an intake port detachably coupled to a first side of the main body and communicating with the dust container;
an adapter detachably coupled to a handle provided at a second side of the main body; and a pipe coupled to the adapter,
wherein the adapter includes: a collar configured to be coupled to a first end of the pipe; and a clamp connected to the collar, wherein the clamp includes:
a first wall connected to the collar; and
at least one second wall rotatably coupled to the first wall, wherein the first wall and the at least one second wall form a space for receiving the handle, wherein the at least one second wall includes a pair of second walls, wherein the vacuum cleaner further comprises:
a latch rotatably coupled to one of the pair of second walls; and
a catch provided at another one of the pair of second walls, wherein the latch and the catch are configured to be detachably coupled to each other, wherein a predetermined space is formed inside the latch, and the catch is detachably inserted into the space,
wherein the at least one second wall includes a pair of second walls, wherein the clamp includes:
a first hinge rotatably coupled respectively to a one end of the first wall and a side end of one of the pair of second walls; and
a second hinge rotatably coupled respectively to another end of the first wall and a side end of another one of the pair of second walls, and
wherein a penetrating portion penetrate through one side of the pair of the second walls, respectively.

8. The vacuum cleaner of claim 7 , wherein each of the first wall and at least one second wall includes a concave surface facing the space for receiving the handle.

9. The vacuum cleaner of claim 7 , wherein the clamp includes a slip prevention layer provided on a surface of at least one of the first wall or the at least one second wall.

10. The vacuum cleaner of claim 7 , further comprising an extension handle detachably coupled to a second end of the pipe,
wherein the extension handle includes a grip located opposite to the pipe, and
wherein the grip includes:
a first grip portion extending away from the pipe by a predetermined length; and
a second grip portion connected to the first grip portion and extending at a first angle with respect to the first grip portion.

11. The vacuum cleaner of claim 10 , wherein:
the intake port is electrically connected to the main body,
the adapter, when coupled to the main body, is electrically connected to the main body,
the pipe, when coupled to the adapter, is electrically connected to the adapter, and
the extension handle, when coupled to the pipe, is electrically connected to the pipe.

12. The vacuum cleaner of claim 10 , wherein the handle includes:
a first handle segment extending from the main body by a predetermined length;
a second handle segment that is connected to the first handle segment and extends at a second angle with respect to the first handle segment; and
a third handle segment connected to the second handle segment and extending at a third angle with respect to the second handle segment.

13. The vacuum cleaner of claim 12 , wherein the first angle between the first grip portion and the second grip portion of the extension handle is within a range of 90% to 110% of the second angle between the first handle segment and the second handle segment that of the handle.

14. The vacuum cleaner of claim 12 , wherein the first angle between the first grip portion and the second grip portion of the extension handle is equal to the second angle between the first extended handle segment and the second extended handle segment of the handle.

15. The vacuum cleaner of claim 10 , wherein the first grip portion includes an extension switch that is configured to provide a control signal to at least one of the main body or the intake port.

16. A cleaner, comprising:
a vacuum cleaner according to claim 7 , and having a cleaner head, a battery, a dust container, and a first handle attached to at least one of the dust container or the battery, the adapter being configured to clamp to the first handle the pipe being configured to be coupled to the adapter; and
a second handle configured to be coupled to the pipe.
