Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a suction head for a vacuum cleaner having a triangular head body.

[0002]

2. Description of the Related Art Conventionally, the suction head of a vacuum cleaner is T
Most of them are shaped like a letter, for example, when cleaning the corner of an L-shaped room, it is common to change the front direction of the head with the hose and clean, or remove the head once and perform the suction operation, In particular, cleaning the periphery of a curved portion such as a table leg is often performed at the end of a hose.

[0003]

As described above, the conventional vacuum cleaner requires time and effort to change the direction of the head when cleaning a corner of a room, and the movement of the cleaner itself in the traveling direction is not always required. There is a problem that it does not go smoothly, and the suction efficiency is poor, and it is difficult to reliably remove dirt in the corners. Meanwhile, remove the head from the hose,
Although the work of sucking dust at the end of the hose is effective for removing dirt, there is a problem that each time it takes time to remove and attach the head from the hose.

[0004] In view of the current situation, some conventional vacuum cleaners have been diligent in improving the internal structure of the head and the outer part of the head, but the outer surface of the vacuum cleaner is in an old state.
There is still no fundamental solution to the above problem.

[0005] In order to solve the various disadvantages of the prior art, the present invention makes the head a regular triangular structure and enables a 360-degree rotation about the suction port of the hose as a fulcrum. To provide a vacuum cleaner head intended to be able to easily clean a bent portion of a room, a lower portion of a column, etc., which is conventionally difficult without changing the direction of the head or removing it. It is an object.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a suction head of a vacuum cleaner having a head main body having a triangular flat shape and a side mountain shape, wherein a suction port of a hose is rotatable at a central upper end of the main body. The arm end protruding from the corner of the bottom plate parallel to the main body arranged on the back inside is fixed to the inner surface of the corner having the suction slit at the lower end of the main body, and the suction space and the suction slit are provided between the main body and the bottom plate. Forming a flow passage for air introduced from the air into the suction port,
The technical means is to implant a brush around the periphery of the bottom plate and to attach a rotor inside the corner.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings. In FIGS. 1 (a) and 1 (b), the head body 1 has a triangular pyramid with a regular triangular planar shape and a mountain-shaped side shape.
When the angle of the inclined surface 2 from the horizontal position is narrowed to 12 to 13 degrees and the length of one side is 30 cm, the height to the central upper opening 3 of the main body is about 4 cm.

The end 5a of the suction port 5 at the base of the suction hose 4 is rotatably fitted to the central upper port 3, so that the hose 4 rotates 360 degrees about the end 5a as a fulcrum. it can. The suction port 5 is not limited to a bellows shape as shown.

Reference numeral 6 denotes a bottom plate arranged inside the back surface of the main body 1, and has a structure parallel to the main body and forms a plane triangular shape and a side mountain shape. The peripheral edge 6a of the bottom plate 6 is flat, and an arm 7 protrudes from three corners thereof, and the end of the arm 7 is a corner 1b having a suction slit S of the lower end 1a of the main body facing inward.
An air passage 8 is formed between the main body 1 and the bottom plate 6 and is fixed to the inner surface.

As shown in FIGS. 1B and 2, the air flow passage 8 communicates with a suction space 9 between the lower end portion 1a of the main body and the bottom plate 6 and a suction slit S. Since the air is sucked by the suction slit S like an arrow finger, the entire circumference of the head main body 1 is, so to speak, a suction portion.

A brush 10 is implanted along the inside of the flat peripheral edge 6a of the bottom plate 6, and inside three corners (inside of the brush).
The ball-shaped rotator 11 is attached to. The brush 10 softly contacts the floor surface according to the movement of the vacuum cleaner and prevents dust from adhering to the rotor 11 so as not to cause friction marks on both the floor surface and the head. The rotator 11 is used to move the head in the front-back, left-right, and diagonal directions, similarly to the existing vacuum cleaner, and is stored and held in a partition space 12 formed between the lower surface of the main body 1 and the bottom plate 6.

Referring to FIG. 3, an example of use of the present invention will be described. FIG. 3A shows the movement of the head when cleaning the floor corner of the wall surface 20 bent stepwise. When one side of the head is brought into close contact with the wall surface of the floor 21 and moves leftward as indicated by an arrow, dust on the floor 21 is sucked into the head. Next, in order to clean the floor 22 in the vertical direction from the corner, the same side of the head is brought into close contact with the vertical wall surface in the same manner as described above. Since the suction port 5 of the hose 4 is rotatably attached to the head main body 1, cleaning can be performed without changing the direction of the hose 4. Further, cleaning of the floor 23 in the depth direction is facilitated by pressing the other side of the head against the wall surface. Also in this case, the hose 1 may be kept in the same orientation, and the head main body 1 automatically comes into contact with the wall surface 20 so that the floor 23 can be thoroughly cleaned. At the corners G of the vertical floor 22 and the horizontal floor 23, corners 1b of the lower end 1a of the head body are provided.
And the dust is sucked into the main body 1 from the suction slit S, so that the dust does not stay in the corner G.

FIG. 3B shows the movement of the head when cleaning the periphery of the lower end of the cylinder 30. First, the head body 1 is pressed against the front of the cylinder 30 as indicated by an arrow, and along the cylinder 30 in this state. Advance the hose 1 in shape. Since the head is constantly in close contact with the cylinder, dust at the lower end of the cylinder is sucked into the main body 1 and any part of the head that has been rotated by slightly tilting the hose 1 comes into contact with the cylinder 30 so that the peripheral edge of the cylinder is reduced. Cleaned evenly.

In the present invention, the angle of the inclined surface 2 can be set arbitrarily, and the structure of the fitting portion between the upper port 3 and the suction port 5 is
The form of the rotor 11 and the mounting means are also objects of the present invention.
The head is not limited to the illustrated ones in the range where the operation and effect is achieved, and the head of course functions similarly not only on the floor surface but also on the vertical surface of the ceiling or wall.

[0015]

As described above, the conventional T-shaped head only cleans forward in the traveling direction, but the head according to the present invention can suck in from the entire circumference of the triangle, so that even a single reciprocation compared to the T-shaped head. The suction efficiency is much better, and the time required for cleaning can be reduced accordingly.

Since the head rotates 360 degrees, one side of the triangle always adheres to the bottom of the wall regardless of the angle at which it hits the wall, so that dust can be reliably absorbed. Further, when the head comes to the corner of the room, it rotates around the vertex of the triangle as an axis, and the other side comes into close contact with the diagonal wall surface, so that the floor corner where the wall rises is efficiently cleaned.

The head can easily follow around the edge of the curved portion such as the circular leg of the table. Even if the head is conventionally cleaned or the head is removed and cleaned with the end of the hose, there is no excess. Can be easily cleaned without any hassle.

The suction slit provided at each corner, which is the vertex of the triangle, has a high negative pressure and cleans the corner of the room very effectively.

Since the thickness can be reduced, and the hose can be tilted down so that every corner of the bed or the like can be placed in a comfortable posture, even the elderly or the sick can clean without burdening the labor.

Since the structure is simple, mass production is possible at low cost, and the entire head can be reduced in weight, there is a benefit that it is convenient to carry and store and easy to handle.
