Description

The present invention relates to a vacuum cleaner replacement nozzle, and more particularly, to a vacuum cleaner nozzle that can be arbitrarily attached and detached in accordance with various thicknesses of the nozzle of the vacuum cleaner.

2. Description of the Related Art Conventionally, vacuum cleaners that are generally used in the home are provided with a wide variety of dedicated nozzles depending on the purpose and object to be cleaned. For example, use a T-shaped nozzle with a large opening area at the suction port for cleaning a wide range such as floors, tatami mats, and carpets, and a nozzle with a small opening area for cleaning a narrow range such as gaps, shelves, and furniture. Is used. Further, for cleaning the gaps in furniture, the corners of the shelves, etc., it is convenient that the tip is formed in an elliptical shape and the nozzle mouth is cut obliquely. These special nozzles attached to the vacuum cleaner are made of synthetic resin such as polypropylene, and are attached to the tip of the flexible hose or extension pipe of the vacuum cleaner and used for a long time together with the main body of the vacuum cleaner. It is.

In addition, sometimes the vacuum cleaner may want to use the vacuum cleaner to clean a dirty place such as a door tap or a veranda, or to clean indoor dirt by a pet such as a cat, bird or dog. It is very convenient to use a vacuum cleaner in such a dirty place because it can be cleaned without getting your hands dirty, but it will contaminate the nozzle's mouthpiece and it will be unsanitary if used indoors in a dirty state. However, since it is extremely troublesome to wash the nozzle with water after each use, there are some which attach an optional removable cover to the suction nozzle. (For example, see Patent Reference 1)

The technique of this patent reference 1 is a bag-like cover in which the periphery of two rectangular sheets is bonded and an opening is provided at the center of one side, and an expansion member is provided at the opening.

In addition, a connection pipe formed in a step shape with a plurality of outer diameters, which can be fitted to the tip of a flexible hose or extension pipe of a vacuum cleaner, and a cylinder attached to the tip of the connection pipe There is a nozzle assembly for a vacuum cleaner composed of a paper-like nozzle. (For example, refer to Patent Reference 2.) This is suitable for use in a clean place where the use of the nozzle part is particularly difficult or a hygienic accessory nozzle by making the nozzle part disposable. Further, the present invention is characterized in that a roll of commercially available toilet paper can be used instead of the paper nozzle.

In addition, replacement nozzles that are suitable for cleaning applications are commercially available, and the connection part of the nozzle is narrowed so that it can be fitted to the tip of a flexible hose or extension pipe with a different inner diameter by a vacuum cleaner. It has a groove along the axial direction in the connecting portion, or a rubber cover is attached to the connecting portion to prevent slipping.

Furthermore, there is a method in which the core of toilet paper is attached to the suction port and is disposable.

Japanese Patent Publication No. 2008-23282 Japanese Patent Publication No. 2002-28110

When cleaning places such as toilets, entrances, and balconies, as well as indoors and futons, it is difficult to use a suction port because of the different types of dirt.
In addition, there is a demand for using vacuum cleaner to remove pollen and ticks adhering to the futon, but because the futon is particularly clean, it feels uncomfortable to use both toilet cleaning and a suction port.
Items that can be washed by the suction port must be washed after cleaning. In addition, using the same suction port for toilets, entrances, and futons makes you feel reluctant to use them as much as you wash them.
The washable material is made of a hard material such as plastic or polypropylene, so it cannot be inserted into various other vacuum cleaners.
For this reason, the conventional cylindrical suction nozzle has a disadvantage that it cannot be attached to other types of vacuum cleaners because the size of the cylinder is not the same unless it is the same model or manufacturer.

The disposable cover of Patent Reference 1 is a rectangular shape, so it covers the T-shaped vacuum cleaner suction nozzle, but the vertical and horizontal widths and thicknesses of the T-shaped suction nozzle vary greatly depending on the model. There is a drawback that it is difficult to use in correspondence with more models.
In addition, the T-shaped nozzle is not suitable for cleaning fine parts such as the corners of the entrance.

In the nozzle assembly of Patent Reference 2, the joint portion to be inserted into the distal end portion of the flexible hose or the extension pipe of the vacuum cleaner is stepped in four stages of diameters from the small diameter to the large diameter sequentially from the distal end side. Is formed. This shape cannot be inserted when the inner diameter of the flexible hose or the extension pipe is caught on the stepped portion. Further, since the joint portion is made of a synthetic resin such as polypropylene, the flexible hose or the extension pipe slips off when the inner diameter is small or large. In addition, if the inner diameter of the pipe is small, only the tip of the joint portion can be connected, so that it can be easily removed during cleaning, so it cannot be adapted to most vacuum cleaners.

For this reason, commercially available mounting nozzles are narrowed toward the mounting opening, and have a groove along the axial direction at the connection part, or a rubber cover is attached to prevent slipping. doing. Traditional mounting nozzles must be constricted because they cannot be inserted along the inner diameter of flexible hoses or extension pipes of various sizes of vacuum cleaners. Must be produced in shape. Forming a constricted shape is technically more difficult than forming a cylindrical shape.
In addition, if it has a groove along the axial direction, it has an inner diameter rather than a slender shape without a groove or a stepped shape with four stages of diameters from a narrow diameter to a large diameter. However, since there is no change in the outer diameter of the connecting portion of the mounting nozzle only by the presence of the groove, an anti-slip effect can be considered, but only a slight variation is absorbed.
Putting a rubber cover will prevent slipping and secure insertion. However, if the contact surface is not large, the anti-slip effect due to friction is reduced, so the width of the corresponding inner diameter is limited, and if only the tip part can be connected, it will easily come off during cleaning, so it is compatible with most vacuum cleaners It's not possible. Also, if the rubber cover is worn and damaged, it must be replaced. Also, just losing the rubber cover will make the entire nozzle unusable.

In this way, there is no replacement nozzle that can be securely inserted into the tip of the flexible hose or extension pipe of most vacuum cleaners. In the current situation, only the dedicated nozzle attached to the vacuum cleaner is often used.

When the toilet paper core is attached to the suction port, there is no resistance to cleaning the toilet or the like, but there is resistance to cleaning the futon with the toilet paper core. In addition, the shape of the toilet paper core does not necessarily fit into the vacuum cleaner inlet, and the shape may not match. In addition, the paper core of the toilet paper is soft and may be crushed during suction. Furthermore, because it is cylindrical, it cannot touch the floor at an angle, so the suction sound is abnormally loud and annoying abnormal noise, and the suction port sticks vertically on the floor and cannot be separated, making it difficult to inhale. is there.

Therefore, the present invention can obtain an effect without molding into a shape narrowed toward the mounting opening, so even if it is a cylindrical shape that is easier to mold than before, the model manufacturer differs and the pipe thickness is different. It can be attached to and detached from many different vacuum cleaner suction nozzles, it can be sucked in contact with the floor with an oblique suction port, and can be disposable, so it can be used for toilets and entrances and can be thrown away when it gets dirty The purpose is to provide a vacuum cleaner replacement nozzle that can be used exclusively in places such as futons that you want to use beautifully.

  Furthermore, by combining with the shape narrowed toward the attachment port, it can be attached to and detached from the vacuum cleaner suction port of various thicknesses.

Furthermore, when the material which can be washed is used, it aims at providing the cleaner replacement nozzle which can be repeatedly used after disinfecting hot water if it gets dirty.

Furthermore, even nozzles made of conventional synthetic resins such as polypropylene are less likely to slip and come off, and can be used as is without attachment to most commonly used vacuum cleaners. Accordingly, it is an object of the present invention to solve such a problem by having a connecting portion in which the range of the inner diameter that can be inserted is wider than the conventional one.

The replacement nozzle for a vacuum cleaner according to the present invention is a replacement nozzle for a vacuum cleaner that is attached to the mouth of the tip of a hose that is connected to the vacuum cleaner, and has a cylindrical body surface. The connecting hose has a connection part to be inserted into the hose opening on the end of the connecting hose, a suction opening on the opposite end of the connecting part, and a vacuum cleaner connected to the outer peripheral surface of the connecting part. It has a connection surface in contact with the inner peripheral surface of the mouth of the tip of the hose, and the connection surface is cut from the peripheral surface of the open end portion of the connection portion.

Furthermore, one cut is formed in the connection surface from the peripheral surface of the open end portion of the connection portion.

Further, the connection surface has a plurality of irregularities.

Further, the connecting portion has a shape narrowed toward the open end portion, and the suction port is cut off obliquely.

Furthermore, it is characterized by being made of a plastic material such as paper or silicon resin.

Furthermore, a plurality of cuts are made in the body surface from the peripheral surface of the open end portion of the suction port, and the peripheral surface of the open end portion has a circular brush shape.

According to the first aspect of the present invention, the cylindrical cylindrical body is easier to mold than the conventional shape narrowed toward the attachment port, and is excellent in manufacturing efficiency. Furthermore, since the connection surface has a notch from the peripheral surface of the hose mouth side connected to the vacuum cleaner, the outer diameter of the nozzle is narrowed at the notched portion, and the outer diameter of the nozzle is reduced to match the inner diameter of the hose. I can do it. In addition, because the connection part of the narrowed nozzle is pressed against the inner peripheral surface of the hose by the force to return, it adheres to many different vacuum cleaner inlets with different pipe thickness without rubber attachment. It is possible.

According to the second aspect of the present invention, since one notch enters the connecting surface from the peripheral surface of the hose leading to the vacuum cleaner, the outer diameter of the nozzle is narrowed at the notched portion, and the outer diameter of the nozzle is reduced to the hose. It can be reduced to match the inner diameter of the. In addition, because the connection part of the narrowed nozzle is pressed against the inner peripheral surface of the hose by the force to return, it adheres to many different vacuum cleaner inlets with different pipe thickness without rubber attachment. It is possible. Furthermore, since only one slit is required, the manufacturing process of the nozzle is minimized, and the manufacturing efficiency is excellent. Moreover, since there is only one cut, the outer diameter of the nozzle can be reduced while maintaining the strength of the nozzle. Furthermore, there is an effect that the body surface is less likely to bend inwardly from a notch portion than when there is a plurality of notches.

According to the invention of claim 3, by having a plurality of irregularities on the connection surface on the mouth side of the hose connected to the vacuum cleaner, slippage of the surface where the inner peripheral surface of the hose mouth contacts the connection surface is stopped. Thus, there is an effect that the nozzle is difficult to come off from the hose.

According to the invention of claim 4, since the vacuum cleaner insertion port side has a shape that is narrower than the tip, it can be fitted to many different vacuum cleaner suction ports with different pipe thicknesses. The slanted suction port allows suction that is in stable contact with the floor.

According to the invention of claim 5, when paper is made of a material such as recycled paper, it can be disposable, so it can be used for toilets and entrances and discarded when it becomes dirty. In addition, it can be used exclusively for places that you want to use beautifully, such as futons. In addition, when using heat-resistant soft materials that can be washed, it can be installed to fit many vacuum cleaner inlets, and can be used repeatedly by disinfecting hot water when it gets dirty. By using such a flexible material, it is possible to mount with a close feeling corresponding to various sizes of the vacuum cleaner insertion port. Further, in the case of paper materials such as recycled paper, the shape of the tip of the nozzle can be changed to an arbitrary shape, so that when the narrow portion is cleaned, the tip can be arbitrarily crushed with a hand or the like.

According to the invention of claim 6, the brush-like shape of the tip can be sucked while cleaning the futon or removing dust.
