Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction device for a floor of a vacuum cleaner, and more particularly, to a suction device attached to a tip of a suction pipe of a vacuum cleaner and provided with a dust suction portion that opens on a lower surface.

Conventional technology Conventionally, as a suction tool with a dust suction part that opens on the bottom surface,
For example, there is a configuration disclosed in Japanese Utility Model Laid-Open Publication No. 63-1111859. As shown in FIGS. 7 to 9, this configuration has a dust suction portion 50 that opens from the lower surface of the suction tool to the front surface, and a shielding plate 51 that opens and closes the front opening on the front surface of the dust suction portion 50. In addition to the above, an arm 52 extending rearward is provided on the shielding plate 51, and the arm 52 is swingably supported by the suction tool main body 56 with the middle of the arm 52 as a fulcrum 53, while the arm 52 is By pressing the other end of the operation button 54 provided on the main body 56, the shielding plate 51 is moved upward to open the front surface of the dust suction unit 50, and the dust on the front wall of the suction tool is sucked. It is made as much as possible.

Problems to be Solved by the Invention By the way, the above-described suction device is a dust suction portion in the suction device.
Although it is possible to open only the front surface of the suction plate 50 by opening the shielding plate 50, a gap cannot be formed between the front surface of the suction device and the wall surface. Can not be lifted at all. Therefore, the flow of air on the front surface and the lower surface of the suction tool is greatly impeded, and there is a problem that the air flow cannot efficiently act on the dust sucked into the dust suction portion 50 from the vicinity of the wall.

In addition, in order to open and close the front surface of the dust suction unit 50 by moving the shielding plate 51 up and down, it is necessary to press the operation button 54 provided on the main body 56 each time. That is, there is a problem with inconvenience that an operator feels complicated.

The present invention has been devised in view of the above-mentioned problems, and its purpose is to reliably suck dust such as near a wall without increasing the number of parts, while having a simple structure and operation and a low failure rate. It is an object of the present invention to provide a floor suction device for a vacuum cleaner.

Means for Solving the Problems The present invention fixes a bumper formed of an elastic material on at least a front surface of the suction tool in a suction tool attached to a tip of a suction pipe in a vacuum cleaner and provided with a dust suction portion opened on a lower surface. In addition, a plurality of projections are provided on the bumper at intervals in the width direction of the suction tool.

According to the above structure, when the suction tool is opposed to the wall surface and the wall is cleaned, a projection further projecting than a bumper fixed to at least the front surface of the suction tool contacts the wall surface. Since the projections are provided with a spacing in the width direction of the suction tool, a gap is formed between the wall surface and the bumper, and this gap and the gap formed between the suction tool lower surface and the floor surface are formed. It serves as an air passage to improve the flow of air around the wall, and as a result, dust can be efficiently sucked from the periphery of the wall into the dust suction portion on the lower surface of the suction tool.

Embodiment A floor suction device of a vacuum cleaner according to the present invention will be described based on an embodiment of the drawings.

FIG. 2 is a cross-sectional view of a suction tool equipped with the present invention,
FIG. 1 shows the external appearance of the suction tool in a plan view. The suction tool is provided with a dust suction portion 1 opening on the lower surface, and a bend portion 2 attached to a suction pipe (not shown) at the rear portion.
A main body 4 that forms a box body by forming a suction passage 3 communicating the inner surface of the bend portion 2 and the dust suction portion 1 and a bumper 5 fixed to the outer periphery of the main body 4 and formed of an elastic material. The bumper has a plurality of projections 6 integrally projecting forward with an interval in the width direction of the main body 4.

The protrusion 6 has a configuration in which a support portion 7 that is inclined forward and downward from the front surface of the bumper 5 and a stopper portion 9 provided with a non-slip 8 at the tip of the support portion 7 are provided. .

As shown in FIG. 3, soft portions 10 and 10 are formed at the base end and the front end of the support portion 7, respectively.
When a pressing external force acts on the front surface of the support portion 7, the soft portions 10, 10 of the support portion 7 are remarkably elastically deformed, and the state in which the support portion 7 leans forward is extremely increased. .

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

When cleaning the wall using the suction tool, the bumper 5
By contacting the front surface of the stopper portion 9 of the projection 6 with the wall surface, and further pressing the suction tool against the wall surface, the stopper portion 9 fits on the wall surface by the action of the non-slip 8 of the stopper portion 9. In addition to preventing the sliding movement of the stopper portion 9 against the wall surface, the soft portions 10, 10 of the support portion 7 are remarkably elastically deformed due to the pressing force, so that the forward tilt state of the support portion 7 downward is extremely large. As a result, the bumper 5 integrated with the support portion 7 naturally floats upward together with the main body 4 for fixing the bumper 5, and separates the lower surface of the suction tool from the floor surface, thereby allowing the lower surface to be separated from the floor surface. A large gap is formed between the gap and the gap between the front surface of the bumper 5 and the wall surface separated from the front surface of the bumper 5 via the protrusion 6, so that the air flow resistance around the wall becomes large. Dust from around the wall Movement of air into, i.e., a powerful suction force supposed to increase the flow rate of air, the wall side usually existing around can be dust suction reliably dust suction hard dust. In addition, the simple structure in which the projections 6 are formed integrally with the bumper 5 reduces the failure rate, and also eliminates the complexity of operating the operation buttons and the like as in the related art.

In this embodiment, the protrusion 6 projecting from the bumper 5 is constituted by a support portion 7 and a stopper portion 9, and the lower surface of the suction tool is placed on the floor by utilizing the elastic deformation of the support portion 7 by pressing force. Although the projection 6 is made to float naturally from the surface, the projection 6 has a simple projection shape as shown in FIGS.
However, in this case, manufacturing can be further simplified.

In addition, the protrusion 6 may be disposed not only on the front surface of the bumper 5 but also on the periphery including the side surface. In this case, dust absorption near the corner of the wall surface is also advantageous.

In any case, the shape and number of the projections 6 and the arrangement position are not particularly limited.

Effect of the present invention As described above, the present invention does not increase the number of parts as compared with the conventional one, and has a simple structure with a low failure rate, and can reliably absorb dust present near a wall, etc. For example, there is an effect that a complicated operation such as an operation button as shown in FIG.
