Description

[Detailed Description of the Invention] The present invention relates to a suction port body for a vacuum cleaner in which valve members are provided in openings provided at both ends of the air passage on the lower surface of the floor suction port body.

The floor suction port used in vacuum cleaners has a relatively large contact area with the floor, and when cleaning by sliding in contact with the floor, the suction force applied from the vacuum cleaner body acts on the floor. Therefore, it has the disadvantage that it is relatively heavy and requires a lot of effort to clean.

If the floor is relatively tightly sealed with the floor, such as a wooden floor or vinyl tile floor, the vehicle will travel easily, but if the floor is relatively tightly sealed with the floor, such as a carpet, the vehicle will travel more easily. Labor also increases.

In this case, a valve member that can be opened and closed at both ends of the air passage provided on the lower surface of the suction port body is provided integrally with the bumper, thereby improving the circulation of intake air and making cleaning work easier. It is an object of the present invention to provide a suction port body for a vacuum cleaner that is simple in structure and inexpensive.

The drawings showing the embodiments of the present invention will be explained below.

FIG. 1 shows a perspective view of the suction port according to the present invention seen from the back side, and numeral 1 indicates the suction port for use on the floor.

Reference numeral 2 denotes a suction port which is open in the center, and this suction port 2 is connected to the tip of an extension pipe or the like, and is sucked by a vacuum cleaner main body (not shown).

Both ends of the suction port 2 are extended left and right to form a suction air path 3.

A front edge 4 of the lower case is provided to protrude from the front surface of the suction air passage 3.

A rear edge 5 of the lower case is provided protruding from the rear surface of the suction air passage 3, and a brush 6 is provided on this rear edge 5 in parallel with the suction air passage 3.

The lower case 7 provided with the front edge 4 and the rear edge 5 is connected to the upper case 8 by screws 9.

Valve members 10 are attached to both ends of the suction air passage 3,
The opening 15 of the suction air path 3 is closed.

This valve member 10 is integrally constructed with a bumper 11 made of soft rubber or the like attached to the side peripheral surface of the suction port body 11.

The bumper 11 is used to protect the suction port body 11 from impact.

The distal end of the valve member 10 is bent outward, forming, for example, a curved portion 12.

The curved portion 12 is higher than the front edge 4 and the rear edge in FIG. 1, that is, it protrudes from the lower surface of the suction port body 11.

Normally, it stands upright due to its own elasticity and blocks the opening 15 of the suction air passage 3, but when cleaning a floor surface such as a carpet 16, the pressing force from the floor surface during operation is reduced. In response to the reaction force, the valve member 10 is pushed upward as shown in the second figure, which has the effect of opening the opening 15 of the suction air passage 3 and improving ventilation.

Reference numeral 13 denotes rollers, which are provided at both ends of the front edge 4 of the lower case 7, and have the function of smoothing the running of the suction port body 10.

The base of the valve member 10 has a hinge function, and normally stands upright due to its own elasticity and closes the opening 15 of the suction air passage 3. However, if necessary, a spring 14 is attached as shown in FIG. It is also possible to attach the suction air passage 3 and pull it in the direction of the suction air passage 3 to forcibly close the inlet.

Since the present invention is constructed as described above, when cleaning a wooden floor or vinyl tile floor, as shown in the left half of FIG. This closes the opening 15 of the suction air path 3, improves the airtightness of the floor, improves the air-filling performance, and efficiently sucks in dust through the gap in the leading edge 4 and the gap in the brush 6 provided in the trailing edge 5. be able to.

When running on a soft floor such as a carpet that has a relatively high degree of sealing with the floor and is frequently traveled, the floor surface pushes the valve member 10 in the longitudinal direction of the suction port due to the pressing force during operation, opening the openings at both ends of the air passage and allowing air to flow through the floor. flows in from the gap.

Therefore, the degree of sealing with the floor is also reduced, and the suction port body 1 can be moved easily (see FIG. 2).

FIG. 3 shows a case where only one roller 13 is provided in the center, and if there are no valve members on the left and right sides, the suction port body 1 swings left and right as shown by dotted lines, and the lower surface of the suction port is on the floor. However, if the valve member 10 is installed, there is no risk of damaging the floor.

Further, by configuring the valve member integrally with the bumper, a complicated mechanism can be omitted and no separate parts are required, resulting in a low cost.

As described above, according to the present invention, by providing the valve member in the openings provided at both ends of the air passage on the lower surface of the floor suction port body, the suction port body can be moved easily, and the valve member can be opened and closed easily. Since manual switching operations are not required, cleaning work can be done easily.

Moreover, since the valve member balances the gap between the left and right floor surfaces of the suction port body, an average suction force can be obtained, and there is no risk of the lower suction surface contacting the floor surface and damaging it, and the valve member can also be used as a damper. By configuring it in one piece, the structure is simple and the price is low.
