Abstract

PURPOSE:To enable the using of a brush member whenever necessary without losing. CONSTITUTION:This device comprises a double structure of an internal pipe 3 which allows the mounting of a suction head of a dust collector 8 or the like or a pipe for connection and an external pipe 4 provided concentrically outside the internal pipe 3 and a circular brush member 6 is inserted into an intermediate part between both the pipes 3 and 4 in such a manner as to allow the sliding thereof. Thus. the dust collector can be used with a brush member 6 mounted on the suction hose thereby enabling the using of the brush member whenever necessary without losing the brush member.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a suction head for use in a vacuum cleaner.

[0002]

A T-shaped dust collector for floor cleaning is generally used as a suction head of an electric vacuum cleaner, but a round brush member is widely used for removing dust from window frames, shelves and the like. There is. Conventionally, this brush member has been separately attached as an attachment, and at the time of use, the dust collector is removed from the tip of the suction hose, and the brush member is again attached to the tip of the suction hose.

[0003]

In the above prior art, when the brush member is used, it is necessary to remove the dust collector and attach the brush member, and to replace it with the dust collector during normal cleaning. .. For this reason, the brush member is lost, or the brush member cannot be used because it is not at hand, which is inconvenient.

It is an object of the present invention to provide a suction head for an electric vacuum cleaner which allows the brush member to be used whenever necessary without losing the brush member.

[0005]

The structure of the present invention for achieving the above object is an inner pipe to which a suction head such as a dust collector or a connecting pipe can be mounted, and a concentric outer pipe. It has a double structure of the outer pipe provided,
A circular brush member is slidably fitted in an intermediate portion between the two pipes.

[0006]

The dust collector can be attached to the suction head 10 with a brush to which the brush member is attached, so that the brush member will not be lost, and the dust collector can be detached at any time to use the brush member. can do.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The tip of the suction hose 1 of the electric vacuum cleaner is configured as a suction head 2 with a brush. The suction head 2 with a brush has a double structure of an inner pipe 3 having a suction hole 3a and an outer pipe 4 concentrically provided on the outer side of the inner pipe 3.
A circular brush member 6 having a brush 5 at its tip is slidably fitted in the hollow portion between the two. A pin 7 is planted in the brush member 6 and projects outward from an L-shaped window 4a provided in the outer pipe 4. A mounting pipe 9 for the dust collector 8 can be mounted in the suction hole 3a of the inner pipe 3.

When the suction head 2 with a brush having such a structure is used, the dust collector 8 is removed, the brush member 6 is pushed forward by the pin 7, and the brush 5 is projected as shown in FIG. It is locked to the key-shaped portion of 4a and used in the same manner as a conventional brush member. Then, when the dust collector 8 is used again, the brush member 6 is moved by the pin 7
, And attach the mounting pipe 9 of the dust collector 8 to the inner pipe 3
It can be attached to.

FIG. 3 shows another embodiment of the present invention. The suction head with brush 10 is provided with a tapered mounting pipe 11, which can be attached to the suction hose 12 of the electric vacuum cleaner, and the other structure is the same as that shown in FIG. It is exactly the same. Therefore, as in the above-described embodiment, the suction head 1 with a brush is used.
When 0 is used, the dust collector 8 is removed, the brush member 6 is pushed forward by the pin 7, the brush 5 is projected, and the pin 7 is locked to the key-shaped portion of the window 4a for use. When the dust collector 8 is used again, the brush member 6 is pulled in by the pin 7 and the mounting pipe 9 of the dust collector 8 is attached to the inner pipe 3. Such a suction head with a brush 10 is convenient because it can be used in a retrofit type while using the existing suction hose 12.

As is clear from the above description, in the case of FIG. 1, the brush member 6 is attached to the suction hose 1 itself, and in the case of FIG. 3, the brush suction head 10 is attached to the suction hose 12. It suffices to attach the dust collector 8 while the brush member 6 is sucked in and attached to the hoses 1 and 12.
Since the brush member 6 can be attached and used, the brush member 6 can be used without removing the dust collector 8 at any time as needed.

In each of the above embodiments, the dust collector 8
Although the case of directly attaching to the inner pipe 3 has been described, it goes without saying that a detachable connecting pipe may be connected to the inner pipe 3 and the dust collector 8 may be attached to the connecting pipe for use. The brush 5 may be detachably provided on the brush member 6. For example, a ring having a threaded portion may be attached to the brush 5, and the brush member 6 may also be provided with a threaded portion to be screwed into the threaded portion of the ring so that the brush 5 and the brush member 6 are screwed together. Alternatively, balls which are urged in the outer peripheral direction by springs are provided at a plurality of locations on the outer circumference of a ring provided on the brush member 6, and conical holes with which the balls engage are also provided at a plurality of locations on the inner circumference of the brush member 6. May be. In this case, the ring with the brush 5 is attached to the brush member 6
When the brush 5 is rotated, the ball engages with the hole and the brush 5 is joined to the brush member 6. When the brush 5 is detachable from the brush member 6 in this way, it is economical because only the brush 5 needs to be replaced when the brush 5 is worn.

[0011]

According to the present invention, since the dust collector can be used with the brush member attached to the suction hose, the brush member is not lost, and the brush member can be used whenever necessary. Can be used.
