Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner, particularly to its suction port body.

BACKGROUND OF THE INVENTION As shown in FIGS. 5 and 6, a brush holder 3 is provided in a groove 2 of a suction port body 1, and the brush holder 3 is moved up and down by an operating body (not shown). There are vacuum cleaners, but they have the following disadvantages:

Problem to be Solved by the Invention In other words, as shown in FIG. 5, when the brush holder 3 is pulled up by the self-operating body, the carpet surface 4 is cleaned. In the conventional one, there is a gap A between the brush holder 3 and both surfaces 2a and 2b of the groove 2.
, B are formed.

For this reason, air is sucked into the intake port 5 as shown by arrows K and L from the control hole (not shown) of the operating body through the gaps A and B, and as a result, the carpet surface 4 The dust in the corners of the air is not sucked into the intake air 05 and remains there. In addition, as shown in FIG. 6, when the brush holder 3 is pulled down and the elastic plate 7 is made to protrude outside the groove 2, the floor surface 8 is cleaned. Air is drawn from the gaps A and B to the negative pressure side of the elastic plate 7 as indicated by arrows M and N.

For this reason, the intake pressure decreases and the lower part of the elastic plate 7 is indicated by the arrow ○.
As a result, the flow rate of the air sucked in becomes slower, and as a result, the dust collection effect of the dust 9 becomes significantly lower. The dust collection effect has been improved. Means for Solving the Problems The present invention solves the above-mentioned drawbacks of the conventional art by providing a suction port body provided substantially perpendicularly to the tip of the connecting pipe, and a suction port body provided on the lower surface of the suction port body. A groove provided in the longitudinal direction,
a brush holder provided within the groove and capable of being moved up and down within the groove by an operating body provided outside the suction port body;
An elastic body is attached to the brush holder and is provided so as to be able to protrude and retract from the premises below the suction port main body in conjunction with the brush holder of the bracket, and the elastic body is provided with the groove formed before and after the elastic body. It has a rib that covers one side of the gap between the braces and slides along one side of the groove of the bracket, and when this rib touches the twill part provided on one side of the groove, the tip of the elastic body is placed in the groove. This was done so that the other side could assist.

Effect: According to this configuration, when the elastic body is protruded, one of the gaps is closed, so air flow in the subordinate M and N is blocked, and when the elastic body is retracted, both gaps are closed. This prevents air from flowing to the intake port.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In FIG. 1, reference numeral 10 is a connecting pipe connected to a vacuum cleaner main body (not shown), and a suction port main body 11 is attached to the distal end of the connecting pipe 10 in the configuration shown in FIG.
That is, this suction port body 11 is rotatably attached to the tip of the connecting pipe 10 by a ring 12'.
In this state, this suction port body 11 and the connecting pipe 1
0 and is in a substantially orthogonal state as shown in FIG.

Further, as shown in FIG. 1, a horizontally elongated sliding hole 12 is provided on the upper surface of the suction port main body 11, and an operating body 13 is drawn out from the suction port main body 11 through the sliding hole 12.

This operating body 13 is supported by a support shaft 14 inside the suction port main body 11 as shown in FIG. The brush lever 15 moves up and down. Then, the brush holder 6 moves up and down in conjunction with the brush lever 15, and as a result, the elastic body 19 and the brush 20 move from inside the grooves 17 and 18 to the suction port body 1.
It appears in the downward direction of 1.

The grooves 17 and 18 are provided in the longitudinal direction of the suction port body 11, and the lengths of the elastic body 19 and the two brushes are approximately the same as these grooves 17 and 18. .

A rib 21 having the same length as the groove 17 is provided on the rear surface of the elastic body 19, and the tip of this rib 21 is provided on the rear surface 17A of the groove 17. The recess 17B is fitted with iron so that it can freely slide upward and downward.
In FIG. 2, 22 is a ball for the click stop of the operating body 13, 23 is a roller, and 24 is an intake hole communicating with the connecting pipe 101. In the above Yokinari,
When cleaning the floor surface 25, operate the operating body 13 to
The elastic body 19 is made to protrude from within the groove 17 as shown in the figure. In this case, among the gaps 17C and 17D formed by the brush holder 16 and the groove 17, the gap 17D is covered by the contact between the rib 21 and the recess 17B as described above. Therefore, the air sucked from the sliding hole 12 passes through the gap 17C as shown by the arrow P, and the elastic body 1
Don't let the negative pressure of 9 overwhelm you. Therefore, the air sucked into the intake square 24 necessarily passes below the elastic body 19 and its intake pressure becomes high, and as a result, the speed of the air passing through this portion becomes extremely high. Then, the dust 26 is vigorously sucked into the intake port 24, and the dust collection effect is extremely high, so that no dust 26 remains. When cleaning the carpet surface 27, the operating body 13 is operated to lift the brush holder 6 upward into the groove 17 as shown in FIG.

Then, in conjunction with this, the lip 21 comes into contact with the recess 17B and lifts up, and when this rib 21 comes into contact with the contact part 178 of the recess 17B, this special lifting force causes the tip of the elastic body 19 to move into the groove 17E. It becomes the force that brings them into contact. As a result, when the brush holder 16 is completely raised, the groove 17 is completely covered by the tip of the elastic body 19 and the rib 21, as shown in FIG. For this reason, air does not flow to the intake port 24 through this groove 17 as in the conventional case, and as a result, the suction force of the intake □ 24 to suck in the dust 28 at the corner of the carpet surface 27 in this figure. becomes extremely strong,
This dust 28 will not remain in the corners.

Effects of the Invention As described above, according to the present invention, it is possible to prevent a drop in the intake pressure of the air sucked into the intake port simply by operating the operating body, and as a result, dust remains on the floor or carpet surface. You can clean it without any problem.

Further, since the operation of the operating body is always performed when switching between cleaning the floor surface and the carpet surface, there is no need for any troublesome operation and the operation can be performed easily. Furthermore, when operating this operating body to move the brush holder up or down, only the ribs provided on the elastic body are in contact with one side of the groove, so there is little frictional resistance and smooth operation is possible. I can do it.
