Description

[Detailed Description of the Invention] This invention relates to a suction body for a vacuum cleaner.

A conventional example is shown in FIG.

Reference numeral 1 has a suction port body (not shown) that holds a rotary tube 2 connected to a vacuum cleaner, and a horizontally elongated suction air passage 3 connected to the suction hole.

Further, a brush 4 is inserted into the suction port main body 1 along the suction air path 3.

The suction port main body 1 is of a so-called two-piece type in which an upper main body 5 and a lower main body 6 are assembled while sealing between them with a bread puff that also serves as a backing.

This bread puff is intended to prevent furniture etc. from being scratched during cleaning, but the work of assembling the upper body 5 and the lower body 6 while holding down the entire circumference of the bread puff by hand to prevent it from protruding outward is necessary. It's extremely troublesome.

In addition, as shown in FIG. 2, there is a type in which a rib 8a having a T-shaped (or L-shaped) cross section is formed protrudingly on the outer periphery of the suction port body 8, and a bumper 8b is fitted into this rib. Such a device has the disadvantage that the bumper 8b easily comes off.

The purpose of this invention is to provide a suction port for a vacuum cleaner that can prevent the above-mentioned drawbacks.

This idea consists of a suction port body that integrally forms a suction hole that rotatably holds a rotary tube connected to the dust collection part of the vacuum cleaner, and a horizontally elongated suction air passage with an opening at the lower end that communicates with the suction hole. A plurality of locking protrusions are formed on the inner surface of a bumper made of a soft material that surrounds the outer peripheral edge of the suction port body, and locking holes for holding these locking protrusions are formed on the outer peripheral edge of the suction port body. The locking protrusion of the bumper is held between the suction port body and the suction port body by a supporting body such as a brush or bellows inserted along the suction air path of the suction port body while preventing the suction port from being removed. It is characterized by being fixed.

Therefore, the bumper can be installed by simply inserting the locking protrusion of the bumper into the locking hole of the suction port body and then inserting the support body. Since the bumper is held between the two, it is possible to prevent the bumper from falling off, and the structure is such that the bumper can be easily attached to an integrated one-piece type suction port body.

An embodiment of this invention will be explained based on FIGS. 3 to 6.

9 is a horizontally elongated suction port body. A horizontally elongated suction air passage 10 having a U-shaped cross section and opening toward the floor is formed on the lower surface of the suction port main body 9, that is, the surface facing the floor. A horizontally elongated recess 13 into which the base 12 of the brush 11, which is a support body, is inserted is formed.

A suction hole 14 that opens toward the floor is formed in the center of the suction air passage 10, and the other end of the suction hole 14 is connected to the dust collecting section of the vacuum cleaner through an extension pipe or a flexible hose. A rotary tube 15 connected to the rotary tube 15 is rotatably fitted therein.

A plurality of notches 16, which are locking holes, are formed on the front edge side and the rear edge side of the outer periphery of the suction port body 9.

Next, a bumper 17 made of a soft material and surrounding the outer periphery of the suction port body 9 is provided.

An L-shaped locking protrusion 18 is formed on the inner surface of the bumper 17 and is inserted through the notch 16.

As shown in FIG. 4, a groove 12a is formed in the base 12 of the brush 11, which is slightly shallower than the thickness of the locking protrusion 18.

In such a configuration, the locking protrusion 18 of the bumper 17 is inserted into the suction port body 9 through the notch 16, and the base 12 of the brush 11 is inserted into the recess 13.

This base 12 has a locking pawl 19 formed at the open end of the recess 13.
Extraction is stopped by.

In this state, the locking protrusion 18 of the bumper 17 goes around one end of the base 12 of the brush 11 and enters the groove 12a of the base 12.

In this state, the locking protrusion 18 of the bumper 17 is directed towards the floor -\
The movement is stopped by one end of the base 12, and the movement in the outer circumferential direction is stopped by the bottom of the groove 12a and the recess 13 of the base 12.
Therefore, the bumper 17 can be prevented from falling off.

Further, the bumper 17 can be easily assembled by inserting the locking protrusion 18 into the notch 16 and inserting the brush 11 into the recess 13, and attaching the bumper 17 to the integrated one-piece type suction port body 9. It is extremely suitable as a means.

Further, the locking hole may be a hole 20 as shown in FIG. 7 instead of the notch 16 having one end open.

Furthermore, the support body is not limited to the brush 11,
Bellows 21 may be used as shown in FIG.

Even in this case, the locking protrusion 18 of the bumper 17 may be held between the base 12 of the bellows 21.

Since this device is configured as described above, the bumper can be easily installed by simply inserting the locking protrusion of the bumper into the locking hole of the suction port body, and then inserting the support body into the suction port body. The bumper can be easily attached to the integrated one-piece suction port body, and the bumper's locking protrusion is held between the support body and the suction port body, preventing the bumper from falling off. It has the following effects:
