[0004]

[Problems to be solved by the device]

 However, in the conventional structure shown in FIG. 9 described above, the brush member 38 is planted so as to surround the suction port 37. When sliding and cleaning, the brush member 38 is bent and falls so as to close the suction port 37 on the side opposite to the sliding direction of the suction port body 31. For this reason, the brush member 38 sweeps away dust on the surface to be cleaned without guiding it to the suction port 37, and the suction port 37 is blocked, so that the cleaning efficiency is lowered.

The present invention has been made in view of the above problems, and an object thereof is to provide a suction port body of an electric vacuum cleaner that can efficiently suck dust even when the brush member is bent.

[0006]

[Means for Solving the Problems]

 The suction port body of the electric vacuum cleaner of the present invention has a main body having a suction port opened on the lower surface facing the surface to be cleaned, and a tip provided on the main body located closer to the center than the periphery of the suction port. An elastic brush member that abuts substantially perpendicularly to the surface to be cleaned, a lower end of the brush member that is above the lower end of the brush member, and a portion of the main body that projects toward the surface to be cleaned from the lower end of the suction member. And a protective member having flexibility provided on the periphery of the mouth.

[0007]

[Action]

 Since the suction port body of the vacuum cleaner of the present invention is provided with the brush member located closer to the center side than the peripheral edge of the suction port, even if the brush member is bent during cleaning, the brush member on the side opposite to the bending direction of the brush member is provided. It securely sucks dust on the surface to be cleaned, which is swept from the suction port by the brush member, and the lower end projects above the lower end of the brush bristles and protrudes from the lower end of the main body toward the surface to be cleaned. The protective member prevents the lower end of the main body from coming into contact with the surface to be cleaned and damaging the surface to be cleaned due to bending of the brush member.

[0008]

【Example】

 Hereinafter, an embodiment of a suction port of an electric vacuum cleaner according to the present invention will be described with reference to the drawings.

In FIG. 1 to FIG. 5, reference numeral 11 denotes a suction port body, and the suction port body 11 has a substantially rectangular tube-shaped body 12 and an upper portion of the body 12 which is inclined upward to form a rectangular tube-shaped body. It has a main body 14 integrally formed in a tubular shape from the projected communication portion 13. The tip of the crane-type suction body 15 attached to a hose body, extension pipe, or the like (not shown) is fitted into the communication portion 13.

A suction port 16 is formed on the lower surface of the body 12 so as to communicate with the dust collection chamber of the electric vacuum cleaner body via a hose body or an extension tube. Further, on the lower surface of the body portion 12, an elongated bridge portion 17 is formed so as to be divided into two along the longitudinal direction of the suction inlet 16 from the edge of the body portion 12 so as to cross the approximate center of the suction inlet 16. Are formed. Further, on the lower surface of the bridge portion 17, brush bristles 18 as a brush member having elasticity, for example, are linearly and continuously planted continuously from the body portion 12 to the bridge portion 17.

Then, on the outer peripheral surface of the body portion 12, the lower end edge is located above the lower end of the brush bristles 18, and the lower end edge projects downward in the direction in which the brush bristles 18 project from the lower end edge of the body portion 12. Then, a flexible belt-shaped protection member 19 is provided along the edge of the suction port 16 so as to surround the suction port 16.

The brush bristles 18 are formed to be short so that dust can be sucked from the surface to be cleaned 20 as shown in FIG. 4 when the tip of the brush bristles 18 comes into contact with the surface to be cleaned 20.

When the brush bristles 18 are bent and the side surfaces of the brush bristles 18 come into contact with the surface 20 to be cleaned, the lower end of the protective member 19 has a surface to be cleaned as shown in FIG. They are provided so as to face each other with a predetermined gap from 20, and the entire lower end edge of the protection member 19 contacts the surface to be cleaned 20 so that the suction port 16 is not blocked. Further, in the protection member 19, when the suction port body 11 is tilted, the main body 14 does not contact the surface to be cleaned 20, but the protection member 19 contacts the surface to be cleaned 20.

Next, the operation of the above embodiment will be described.

At the time of cleaning, the communication portion 13 of the suction port body 11 is fitted and attached to the tip of the crane type suction body 15 attached to the tip of the hose body connected to the electric vacuum cleaner body (not shown). Then, the tips of the brush bristles 18 are brought into contact with the surface 20 to be cleaned, the tips of the brush bristles 18 are scraped off, and the sides of the brush bristles 18 are swept up for cleaning.

When the tips of the brush bristles 18 contact the surface to be cleaned 20 during this cleaning, as shown in FIG. 4, suction holes opening on both sides of the bridging portion 17 where the brush bristles 18 are planted. Aspirate dust scraped from mouth 16.

Further, as shown in FIG. 5 during cleaning, when the suction port body 11 is pressed against the surface to be cleaned 20, the brush bristles 18 are elastically deformed and bent, and the side surfaces of the brush bristles 18 are covered. When coming into contact with the cleaning surface 20, the dust swept on the side surface is sucked from the suction port 16 which is not closed by the brush bristles 18 on the side opposite to the bending side of the brush bristles 18.

Therefore, the brush bristles 18 are implanted so as to traverse the suction port 16, that is, since the suction ports 16 are opened on both sides of the brush bristles 18, the brush bristles 18 are scraped or swept. Dust is sucked in through the suction ports 16 that are open on both sides of the brush bristles 18, so the brush bristles 18 sweep dust away from the suction ports 16 toward the outside as in the past. It is possible to prevent the inability to suck and to reliably suck dust. Further, since the suction ports 16 are open on both sides of the brush bristles 18, even if the brush bristles 18 are bent to one side, the other side of the suction port 16 is always open, so that dust can be reliably sucked.

On the other hand, when the suction port body 11 is slid on the surface to be cleaned 20 with the brush bristles 18 bent, the suction port body 11 has the lower surface of the body 12 against the surface 20 to be cleaned. When tilted to an inclined state, the lower end of the main body 14 does not come into contact with the surface to be cleaned 20, but the flexible protection member 19 comes into contact therewith.

Therefore, the surface to be cleaned 20 is not scratched by the main body 14, and damage to the surface to be cleaned 20 can be prevented.

Next, another embodiment will be described with reference to FIG.

In FIG. 6, the bridge portion 17 in which the brush bristles 18 of the embodiment shown in FIGS. 1 to 5 are planted is formed by bending in an S shape.

According to the embodiment shown in FIG. 6, the efficiency of scraping dust by increasing the bristle bristles 18 can be improved, and when the bristle bristles 18 bend, the tip of the bristles bends the bridging portion 17 in a bent state. Similarly, the S-shaped irregular state is created, and the suction port 16 on the bending side of the brush bristles 18 is opened without being partially blocked, and the dust suction efficiency can be improved.

Next, still another embodiment will be described with reference to FIG.

In FIG. 7, the bridging portion 17 in which the brush bristles 18 of the embodiment shown in FIGS. 1 to 5 are planted is formed in a substantially square shape.

That is, a central suction port 16 having a diameter substantially the same as that of the body portion 12 is opened at approximately the center of the bridging portion 17, and brush bristles 18 are planted so as to surround the central suction port 16.

According to the embodiment shown in FIG. 7, the ratio of the area of the suction port 16 closed by the bending brush bristles 18 can be made smaller than the ratio of the area of the opening suction port 16 and the dust suction efficiency is improved. Can be improved.

In each of the above-described embodiments, the structure in which the suction port body 11 is attached to the crane-type suction body 15 has been described, but the suction port body 11 to be attached to the hose body and the extension pipe, and the bottom surface of the electric vacuum cleaner body are described. It is also possible to provide the suction port body 11 having the suction port 16 with the brush bristles 18.
