2. Description of the Related Art Conventionally, this kind of suction device is, for example,
The configuration shown in Japanese Patent Laid-Open No. 33110 has been common. The configuration will be described below with reference to FIG. 7.

Reference numeral 1 is a main body of a suction tool, which is molded from a soft material such as soft vinyl chloride. The inside of the suction tool main body 1 is formed to be hollow, one end of which is provided with a suction port 2 and the other end of which is provided with a connection port 4 for rotatably connecting a connection pipe 3. A brush holding groove 5 is formed all around the end of the suction tool body 1 on the suction port 2 side, and an annular brush holder 7 holding a soft brush 6 is inserted into the brush holding groove 5 and the brush holding groove 5 is inserted. It is sandwiched between the inner wall and the outer wall that form 5.

The length of the protrusion of the brush 6 from the end of the suction port 2 is generally such that when the dust is sucked in, the brush 6 falls into the suction port 2 over the entire circumference due to the amount of suction air and the resistance of the dust. Therefore, even at this time, it is set to 10 to 20 mm in order to prevent the tips of the brushes 6 from coming into contact with each other and blocking the dust suction passage.

[0005]

However, in the case of a structure having a large suction port 2 and a short brush 6, the cleaning surface can be cleaned in a wide area such as a carpet, floor, fold, flat surface of furniture, etc. Since the suction port 2 is large and the distance to the surface to be cleaned is short, dust can be sucked in instantly, and since the area covered by the brush 6 is large, the number of times the surface to be cleaned is moved is small and the suction performance is high. Is sufficiently obtained and there is no problem in practical use.

On the other hand, for cleaning work where the surface to be cleaned is uneven such as furniture gaps, electric appliance lattices, aluminum sash grooves, crosspieces, corners, etc., the length of the brush 6 is short, so Since the tip of the brush 6 does not reach the bottom of the brush, the dust that has stuck cannot be ejected, and cleaning cannot be completed completely. Also,
For cleaning the curtains and cleaning the table cloth, etc., since the suction port 2 is large and the entire circumference is surrounded by the brush 6, the suction pressure is applied to the cloth or sheet that has a thin suction pressure and sticks to the cloth to continue the cleaning work. Can not be. Therefore, in order to solve the problem, the power of the vacuum cleaner is turned off to eliminate the suction force, and then the sucked curtain is removed, so that an efficient cleaning work cannot be performed.

Further, for cleaning work in small places such as a desk or a drawer of a mirror stand, since the area of the suction port 2 is large, dust can be sucked in simultaneously with an eraser, a clip,
You will inhale even things that are difficult to inhale, such as lipsticks and seals. In order to avoid this, it is necessary to arrange and remove the things that are difficult to inhale in advance, which makes cleaning work very inefficient. There are problems as described above, and improvement thereof has been strongly desired.

The present invention is intended to solve the above problems, and includes carpets, floors, furniture other than tatami mats, electric appliances, aluminum sash grooves, crosspieces, desks, uneven parts such as corners, three-dimensional surfaces,
A first object of the present invention is to provide a suction tool which scavenges dust in small places and which has good suction performance and is easy to use.

A second object of the present invention is to improve the dust-exhausting performance and to obtain the optimum suction according to the cleaning place.

A third object is to prevent the suction cylinder from being clogged with dust and to improve usability without requiring maintenance.

Further, while sufficiently securing the opening area of the suction passage, the suction force from the tip of the suction cylinder is strengthened to reduce the load on the electric blower built into the main body of the electric vacuum cleaner and to endure it. The fourth purpose is to improve the sex.

A fifth object is to expand the range of use of the suction tool.

[0013]

The first object of the present invention, which achieves the above-mentioned first object, is to provide a suction cylinder in the substantially central portion and to form a suction passage outside thereof. And further enclosing the outside thereof with a brush to a position longer than the tip of the suction cylinder, and providing a suction tool main body at the suction rear portion of the brush substrate having the suction passage, the suction cylinder and the brush, A connection pipe is attached to the rear of the suction tool body.

A second object of the present invention to achieve the second object is to provide a brush having a fiber diameter of 0.3 to 0.3.
It is formed of 0.7 mm nylon fiber, and further, the protruding length from the brush substrate is set to 40 to 80 mm, and they are bundled and planted on the brush substrate. A third object of the present invention to achieve the third object is to form a suction cylinder with a soft material such as soft vinyl chloride or silicone rubber, and to make the inner diameter of the tip of the suction cylinder a brush. The diameter is smaller than the inner diameter of the base portion of the attachment to the substrate.

Further, a fourth object solving means of the present invention for achieving the fourth object is to construct a skirt-shaped air volume adjusting plate at the base of the suction cylinder.

Further, a fifth means for solving the problems of the present invention which achieves the fifth object is to form the planting of the brush in a U-shape by opening a part of the portion near the surface to be cleaned at the time of cleaning work. It was done.

[0017]

With the above first means for solving the problem, the tip of the brush easily enters the bottom of the recessed portion of the furniture, the back of the lattice portion of the electric appliance, the groove of the aluminum sash, the crosspiece, the corner, etc., It has the ability to squeeze out stuck dust. Also, there is a thin suction cylinder near the tip of the brush, and the dust that has been scraped off and released from the surface to be cleaned is sucked in. The dust is released from the surface to be cleaned and can be easily absorbed even with a weak suction force. Also, when cleaning the curtain, table cloth, etc., suction is performed at the tip of the suction cylinder, but since the entire circumference in the vicinity is surrounded by a brush to prevent further suction, the suction tool moves. It will be easier and you can continue the cleaning work.

Further, even in a small work such as a desk or a drawer of a mirror stand, since the inner diameter of the suction cylinder is relatively small, objects such as poppies, clips, lipsticks, and seals that are difficult to suck are not sucked. , Only the sticky dust scraped off at the tip of the brush is absorbed, and efficient cleaning work can be performed.

Further, by the second means for solving the problem, the brush tip can be easily brought into contact with the groove bottom, the corner or the like of the aluminum sash to improve the scraping performance. The depth of the groove bottom of the aluminum sash used in general households is generally 30 mm or less, and the brush length is set to be more than that. Further, in order to generate a strong pressing force on the tip of the brush, the fiber diameter of the brush and the fiber length of the brush are set to optimum conditions to obtain the bending action of the brush.

Further, according to the third means for solving problems, the size of the dust sucked by the cleaning work is due to the action of being sorted by the inner diameter of the tip of the suction cylinder, and passed through the tip of the suction cylinder. Since the inner diameter of the dust increases as it goes inside the suction cylinder, it is absorbed without contact resistance. Therefore, the suction cylinder is not clogged with dust and no maintenance is required, which improves usability.

Further, according to the fourth means for solving the problems, the uneven portion and the like are sucked by the tip portion of the suction cylinder, and the flat portion and the like of the furniture are
The suction tool is slanted to contact the surface to be cleaned from the center to the tip of the brush to sweep out dust. The released dust passes through the gap at the base of the brush and is sucked from the suction passage on the outer periphery of the base of the suction cylinder. At this time, the balance between the suction force from the tip of the suction cylinder and the suction force from the suction passage on the outer periphery of the root of the suction cylinder is a problem, and if the suction force from the tip of the suction cylinder is strengthened, The skirt-shaped air volume adjustment plate formed on the entire circumference of the root part of the suction cylinder rectifies the suction air volume passing through the suction passage to reduce the pressure loss and maximize the opening area of the suction passage. Then, the outer wall of the air volume adjusting plate on the suction passage side is padded to increase the suction air volume on the suction cylinder side. This method is a work for shaving a die, and the construction is easily completed.

Further, according to the fifth means for solving the problems, in the flat surface portion of the furniture or the like, the suction tool is slanted to be brought into contact with the surface to be cleaned from the central portion to the tip portion of the brush to sweep the dust. The released dust passes through the gap at the base of the brush and is sucked from the suction passage on the outer periphery of the base of the suction cylinder. At this time, the suction airflow passes through the gap at the root of the brush, but the suction airflow is operated so that the resistance of the brush or the like is eliminated and the suction airflow smoothly flows.

The operation of the above configuration is as follows.
The tip of the brush 15 can easily enter the bottom of the recessed part of the furniture, the back of the lattice part of the electric appliance, the groove of the aluminum sash, the crosspiece, the corner, etc., and the sticking out dust can be ejected. Also, a thin suction cylinder 13 is provided near the tip of the brush 15.
There is a tip of the, and dust that is scraped out and released from the surface to be cleaned is sucked in. The dust is released from the surface to be cleaned and can be easily absorbed even with a weak suction force. Further, even when cleaning the curtain, the table cloth, or the like, the tip of the brush 15 projects from the suction cylinder 13, so that even if the brush 15 is adsorbed by the tip of the suction cylinder 13, the brush 15 has the entire circumference in the vicinity thereof. Since the action of enclosing the suction tool to prevent further suction occurs, the suction tool can be easily moved and the cleaning operation can be continued.

Further, even in a small work such as a desk or a drawer of a mirror stand, since the inner diameter of the suction cylinder 13 is relatively small, objects such as poppies, clips, lipsticks, and seals which should not be sucked are sucked. Instead, only the sticky dust scraped off at the tip of the brush 15 is absorbed, and efficient cleaning work can be performed.

Next, a second embodiment of the present invention will be described.
The brush 15 is made of nylon fiber having good wear resistance, and the protruding length from the brush substrate 16 is set to 40 to 80 mm. The fiber diameter of the nylon fiber is φ0.3 to φ0.
It is set to 7 mm. Further, the brush 15 is made by bundling nylon fibers to a diameter of about 3 mm and is planted on the brush substrate 16 at regular intervals. Therefore, at the root of the brush 15, a gap is formed between the brushes 15.

The operation of the above configuration is as follows.
The depth of the groove bottom of an aluminum sash in a general household is generally 30 mm or less, and the tip of the brush 15 is a size that sufficiently abuts on the groove bottom. This is to improve the performance of scraping dust out of the brush 15. This is to generate a strong pressing force on the tip of the brush 15 by the bending action. Fiber diameter φ0.
If it is 2 mm, the brush 15 will be bent in the middle to make it unusable, and if it is φ0.8 mm, it will be unusable in terms of quality because it will scratch the surface of furniture or the like.

Next, a third embodiment of the present invention will be described.
The suction cylinder 13 is made of a soft material such as soft vinyl chloride or silicon rubber. In this embodiment, a molded product of soft vinyl chloride is used. Further, the inner diameter of the suction cylinder body 13 is formed so that the suction tip portion is smaller in diameter than the mounting base portion. The attachment root of the suction cylinder 13 is inserted and fixed to the attachment cylinder 17 integrally formed with the brush substrate 16 via an adhesive.

The operation of the above configuration is as follows.
Explaining the state during cleaning work, the cleaning surface such as uneven parts is
Dust is ejected from the tip of the brush 15 to release the dust from the surface to be cleaned and is absorbed from the tip of the suction cylinder 13. In addition, in the flat surface portion of the furniture, the suction tool is slanted and the brush 15 is brought into contact with the surface to be cleaned from the substantially central portion to the tip portion, and dust is swept from the surface to be cleaned by sweeping dust on the belly of the brush 15. Is released, passes through the gap at the root of the brush 15, and is sucked from the suction passage 14 on the outer circumference of the root of the suction cylinder 13. At this time, the balance between the suction force from the tip of the suction cylinder 13 and the suction force from the suction passage 14 is a problem. The opening area of the suction passage 14 is maximized by the action of rectifying the suction air volume passing through the suction passage 14 and reducing the pressure loss by the skirt-shaped air volume adjusting plate 18 formed on the entire circumference of the base portion of the cylindrical body 13. Then, the load on the electric blower built in the vacuum cleaner body is reduced. Then, the outer wall of the air volume adjusting plate 18 on the suction passage 14 side is padded to adjust the suction air volume on the suction cylinder 13 side.
This method is an operation of shaving a die for molding the brush substrate 16, and the operation is easily completed.

Next, a fifth embodiment of the present invention will be described with reference to FIG. Brush 15 planted on brush substrate 16
Is a brush 1 on the part closest to the surface to be cleaned during cleaning.
5 is not implanted, but the opening 19 is formed, and the brush 15 is implanted in a U-shape.

The operation of the above configuration is as follows.
In the state during the cleaning work, in order to widen the cleaning area, the flat surface portion of the furniture is slanted, and the suction tool is slanted so as to contact the surface to be cleaned from the substantially central portion of the brush 15 to the tip portion thereof.
The dust is released from the surface to be cleaned by sweeping the dust with the belly of 5, and the dust is sucked from the suction passage 14 through the opening 19. At this time, even a small amount of dust such as cotton dust, paper waste, lint, confectionery waste, and the like can be sucked in without being caught in the opening 19, and a suction tool with a wide range of use can be obtained. Further, the brush 15 is planted in a U shape and acts so as to cover the convex portion of the surface to be cleaned to improve the sweeping effect and the suction effect. Also,
As another use, the cotton dust and the like accumulated in the valleys of the seams of the duvet can be sufficiently sucked by cleaning with the suction tool of the present invention to such an extent that it is swept lightly.

[0034]

As is apparent from the above embodiments, according to the first means of the present invention, the suction cylinder of the soft material is provided at the substantially central portion, and the suction passage is formed outside thereof. Furthermore, a brush substrate that is integrally formed by surrounding the outside with a brush to a position that is longer than the tip of the suction cylinder, and a suction tool main body at the suction rear part of this brush substrate are provided. It is composed of a connecting pipe that fits on the cleaner side,
The tip of the brush easily enters the bottom of the recess such as the gap of furniture, the back of the grid of electric appliances, the groove of the aluminum sash, the corner, etc., and the dust sticking out can be ejected. Further, the suction cylinder makes it possible to easily suck dust that has been scraped out and released from the surface to be cleaned even with a weak suction force. Also, when cleaning the curtain, table cloth, etc., it is adsorbed at the tip of the suction cylinder, but since the entire circumference in the vicinity is surrounded by a brush to prevent further adsorption, the suction tool can be easily moved and cleaned. You can continue to work. In addition, when cleaning small parts such as the desk or the drawer of the mirror stand, since the inner diameter of the suction cylinder is relatively small, things such as eraser, coins, lipstick, and seal that are difficult to suck will not be sucked in, and you can scratch with the tip of the brush. Only the dust that sticks out can be absorbed, and a suction tool with good suction performance and good usability can be obtained, and efficient cleaning work can be performed.

According to the second means, the brush is made of nylon fiber, and the protruding length from the brush substrate is 40 to 40 mm.
The fiber diameter is set to 80 mm and the diameter is set to φ0.3 to φ0.7 mm, and they are bundled and planted on a brush substrate. The groove depth of an aluminum sash in a general household is generally 30 mm or less. The tip of the brush has a size enough to come into contact with the bottom of the groove. This is to improve the performance of scraping out dust, and a strong pressing force can be generated against the tip of the brush due to the bending effect of the brush.

By the third means, the suction cylinder is made of a soft material such as soft vinyl chloride or silicone rubber, and the suction cylinder has an inner diameter smaller than that of the mounting root. Since it is formed like this, the size of the dust sucked in by the cleaning work is sorted by the inner diameter of the tip of the suction cylinder, and the dust passing through the tip of the suction cylinder has an inner diameter as it goes inside the suction cylinder. Since it becomes larger, dust is absorbed without contact resistance, dust is not clogged inside the suction cylinder, maintenance is unnecessary, and usability can be improved. Further, even if the tip portion of the suction cylinder body comes into sliding contact with or comes into contact with the surface of furniture or the like, it can be used without anxiety, and the quality can be improved.

Further, by the fourth means, a skirt-shaped air volume adjusting plate is formed on the inner wall side surface of the suction passage, that is, on the entire circumference of the mounting root of the suction cylinder, so that the suction cylinder can be used for cleaning work. There are cases where dust is sucked from the tip of the body and dust is sucked from the suction passage at the base of the attachment of the suction cylinder, and the balance of the suction forces is a problem.Temporarily, the suction force should be increased from the tip of the suction cylinder. In this case, the air flow adjustment plate rectifies the amount of suction air passing through the suction passage to reduce the pressure loss to maximize the area of the suction passage, and the electric blower built in the vacuum cleaner body. The load on the suction airflow adjusting plate is reduced, and the outer wall of the airflow adjusting plate on the suction passage side is overlaid to adjust the suction airflow amount on the suction cylinder side. This method is an operation of shaving a die for molding a brush substrate, and the operation can be easily completed.

Further, by the fifth means, the brush planted on the brush substrate has an opening formed without planting the brush at the portion closest to the surface to be cleaned at the time of the cleaning work. The planting is U-shaped, and the flat parts of the furniture are
In order to increase the cleaning area, the suction tool is slanted and brought into contact with the surface to be cleaned from approximately the center to the tip of the brush,
The dust is released from the surface to be cleaned by sweeping the dust with the belly of the brush, passes through the opening, and is sucked from the suction passage. At this time, even a little larger dust such as cotton dust, paper waste, lint, confectionery waste, etc. can be sucked in without being caught in the opening, so that a suction tool with a wide range of use can be obtained. In addition, the brush is planted in a U shape and acts so as to cover the convex portion of the surface to be cleaned and the sweeping effect,
The suction effect is improved. In addition, as another use, cotton dust and the like accumulated in the valleys of the seams of the duvet can be sufficiently sucked by cleaning with the suction tool of the present invention.
