[The purpose of the device]

 The present invention relates to a device for cleaning earwax adhering to the external ear canal, and in particular, it is an earpick suitable for infants and children whose ear canal is easily damaged and whose hole is too small to clean. The idea is to provide earpicks that can be picked up after picking up earwax.

[0002]

[Prior art]

 The secretions from the earwax line, which is a kind of sweat glands that open to the ear canal, are a mixture of exfoliated epidermis of the ear canal, fat, and dust that adhere to the ear canal. As long as a healthy human body occurs regardless of age or sex, ear picking to remove it is one of the everyday headlines like nail clippers. However, if this earwax neglects daily earpicking and is left in the ear canal, it may become a yellow or dark brown lump and block the ear canal. It is also known to suffer from an ear disease called earwax embolism with symptoms such as earache, deafness, dizziness, and feeling of blockage. Therefore, in order to prevent such ear diseases, it is necessary to scrape the earwax adhering to the ear canal and make it a habit to keep the ear canal clean on a daily basis. Especially in the case of infants who cannot pick up their own ears, such as infants, parental habits are extremely important.

It is already well known that the most common tool for cleaning earwax, so-called earpick, is a bar-shaped tool with its tip bent into a spoon. Is. For example, in 1991 Utility Model Registration Application No. 22518, the traditional earpick is improved and the tip shape of the earpick is made into a dish shape, which has this kind of tip shape. Earpicks are used by peeling off the earwax adhering to the epidermis of the external auditory meatus at its tip, and then placing it on a dish-shaped earpick part and taking it out, or when it is young, the external ear canal is conveyed and scraped off.

With this type of traditional earpick removal method, the earwax can be successfully removed even when the other person's earwax is being cleaned by visual inspection, as when a mother cares for an infant. Placing it on the tip of a traditional earpick and removing it is a difficult task, and if you use this earpick as an earwax-pulling-out type, you can scratch the outer ear canal while repeatedly scratching the earwax. In some cases, unforeseen circumstances such as invasion of bacteria through the wound and inflammation could occur.

In order to solve the above-mentioned problems, tweezers are attached in the direction opposite to the earpick portion, that is, on the rear end side, as disclosed in the invention for utility model registration No. 129562 in 2004. A structure with a different structure has been proposed, and the usage is tweezers in which the earwax is scraped off with the earpick part and can be put on or taken out in the ear canal, and the earwax that stops inside the ear canal is prepared in the direction opposite to the earpick part. It was made so that it could be picked up and taken out.

According to the method of picking and taking out with the tweezers, although the problematic part of the traditional earpick can be avoided for the time being, the tweezers combined type tweezers part is usually commercially available. Like tweezers, it has a structure that opens and closes in the left-right direction, making it unsuitable for the operation of picking earwax in a narrow external ear canal, and it is difficult to control the force of pinching, and if too much force is applied, it will be lumpy when picked. It was hard to say that it was practical because the earwax collapsed and fell apart, and then there was a risk that it could not be picked. In addition, since this earpick has the earpick and tweezers arranged symmetrically on a straight line, once the earpick has scraped the earwax, the earpick is replaced and the tweezers are reinserted into the ear canal. It was accompanied by the hassle of having to take it out.

[0007] In view of the above situation, the present invention has continued to search for earpicks suitable for infants and children who have particular difficulties, and as a result, finally, as described in detail below, in the vertical direction, that is, in the ear canal. By opening and closing the earwax in the direction of the hole and picking the earwax, we have developed an earpick with a new structure that makes it easy to pick the earwax even in a narrow ear canal.

[0008]

[Constitution of device]

 As can be understood from the representative embodiment shown in the drawings, the present invention basically has the following configuration. That is, an ear-picking main rod made of a spatula-shaped thin rod whose tip is bent, and a slide rod having a pressing portion smaller than the ear-picking main rod spatula-shaped portion at the lower end and an operating portion at the upper end. As for the slide rod, the pushing part that is interlocked with the pushing down operation of the operating part can slide up and down from a predetermined position on the upper surface of the spatula-shaped part of the main rod of the ear-picking rod to the upper surface of the spatula-shaped part of the main rod of the ear-picking rod. The earpick is characterized by being regulated and combined with the main earpick.

The ear-picking main rod is a spatula-shaped part having a bent tip and is made of a thin rod as a whole. At least a part within a predetermined range from the tip can be inserted into the ear canal, particularly its cross-sectional shape. The external appearance is not limited, and can be appropriately selected in consideration of manufacturing cost, design effect, and the like. The spatula-shaped part is formed by bending the tip of the ear-picking main rod at an angle within a range of 30 to 90 degrees, optimally 30 to 60 degrees, and its upper surface is operated by the pressing portion of the slide rod tip described later. It must be able to perform the function of maintaining the earwax in place. The structure and shape of the spatula-shaped part itself is specified if it is a convenient shape for scraping or placing earwax, such as a flat-shaped part with a slightly recessed center. Not a thing.

The ear-pick main rod may be formed of a material having an appropriate elastic strength, and the entire body is formed of a single material so that only the spatula-shaped portion does not damage the epidermis of the external auditory meatus. It is formed by using materials such as rubber and soft plastics, and the other main body parts are made of metal, hard plastics, wood or bamboo, etc., that is not brittle and has an appropriate elasticity, and then finally both Of course, the thing which made it integrated is included.

The slide rod has a rear end formed as an operating portion and a front end formed as a pressing portion, has a cross section and a length convenient for abutting on the above-mentioned ear-scraping main rod, and is repeatedly pressed down by a finger. It is made of a fine material having appropriate rigidity, such as a thin steel rod, which is not deformed or damaged by. The pressing portion is smaller than the size of the spatula-shaped portion of the ear-picking main rod, and is bent and formed at the tip of the slide rod at an angle substantially equal to the bending angle, and is interlocked with the operation of the operation part at the rear end of the slide It also functions to press the earwax against the upper surface of the spatula-shaped part of the main rod of the earpick.In addition, even if the pressing force becomes a little stronger, the force is transmitted directly to the earwax by moderate elastic deformation. It is desirable to form the structure so that it does not end up.

The operation portion is formed at the rear end of the slide rod and has a function of realizing a forward operation with respect to the main earpick rod by operating a finger. Therefore, the operation portion has a shape and structure that is easy for the finger to operate. For example, a thin steel rod should be bent in a ring shape, or a bead-shaped one should be capped and integrated at the rear end of the thin steel rod.When it is attached to the earpick main rod, The operating portion is combined with the ear-picking main rod by a combination structure capable of maintaining a state in which it is projected from the rear end of the ear-picking main rod by a predetermined length. In addition, the slide rod is integrally formed of the same material, and only the operation part and the pressing part are made of the optimum materials to exert their functions to form the main body. It is of course possible to form and integrate hard plastics, metal, wood, etc., which are not deformed or damaged, in a separate process at both ends of an appropriately rigid thin material.

The above-described combined structure of the ear-picking main rod and the slide rod basically has a spatula-shaped portion formed at each tip by sliding the slide rod only in the axial direction with respect to the ear-picking main rod. It is an essential requirement that the pressing parts can be vertically overlapped with each other, and ideally, the pressing parts should be advanced to the upper surface of the positioned spatula-shaped part so that they can overlap each other. As a side-by-side structure for that, for example, a groove is provided in the axial direction of the ear-picking main rod so that the slide rod can be fitted, and a hollow portion is provided at or near the axis of the ear-picking main rod, and at least the slide is provided. A structure in which the pushing part of the rod and the operating part project from the ear-picking main rod so that the slide rod is housed in the same hollow part, or conversely, a hollow part is provided on the side of the slide rod and the ear-picking main rod is installed. Collect It is possible to employ a combination structure, such as a storage structure, as appropriate, and therefore, any structure that can realize the basic structure can be installed using any known or known structure. The following examples are some of the typical examples in which the effects of this invention can be expected most.

[0014]

[Embodiment 1] This embodiment is one of the most typical embodiments characterized by the combined structure of a slide rod and an ear-picking main rod, in which a longitudinal elongated groove is formed in the axial direction of the surface of the ear-picking main rod 1. This is due to the structure in which 12 is formed and the slide rod 2 is housed in the narrow groove 12.

The ear-picking main rod 1 is made by processing bamboo material as a whole to be integrally formed, and the tip of a thin rod-shaped main body having an appropriate length is bent to the surface side by about 45 degrees to adjust the shape. The spatula-shaped portion 11 is formed into a spatula-like planar shape, and a vertically elongated narrow groove 12 for slidably storing the slide rod 2 is formed in the substantial center of the front side of the earpick main rod 1. Formed along the entire length in the axial direction. In the figure, the main body of the ear-picking main rod 1 and the spatula-shaped portion 11 on the tip side are shown as having substantially the same width. However, in the case of infants, the spatula-shaped portion 11 side is gradually widened. It is desirable to have a narrowed structure.

The main body of the slide rod 2 is formed of a wire-like thin steel material, and the tip side thereof is approximately 42 to 43 degrees which is slightly smaller than the bending angle of the spatula portion of the ear-picking main rod 1 described above. It is desirable to bend and form it at an angle of a degree, and a pressing portion 21 made of a small cocoon-ball-shaped soft plastic material is capped and integrated at the same position, while a finger operation is performed at the rear end. The operation part 22 made of plastics, which is formed in a drop shape so as to be easy, is capped and integrated. In the figure, a protrusion 23, which is provided at a predetermined position below the operating portion 22 and is orthogonal to the axis of the main body of the slide rod 2, is hooked on the upper end of a restoring member 3 described later and receives the restoring force of the restoring member 3. It fulfills its function.

The combination structure of the slide rod 2 and the ear-picking main rod 1 is such that the main body of the slide rod 2 is forcibly fitted into the narrow groove 12 of the ear-picking main rod 1, and the slide rod 2 is slid from the thin groove 12. The rear end side of the ear-picking main rod 1 and the slide rod 2 is connected by a coil spring which is a restoring member 3, and the rear end of the coil spring 3 is slid. It is realized by being integrated with the protrusion 23 of the rod 2. The resilience of the restoring member 3 is extremely smooth on the tip pressing portion 21 side by sandwiching the main body of the earpick main rod 1 with the index finger and the middle finger and lightly pushing the operating portion 22 of the slide rod 2 with the belly of the thumb. It comes into contact with the upper surface of the spatula-shaped portion 11 of the ear-picking main rod 1, and when the force of the thumb is released, the slide rod 2 retracts naturally, and the pressing portion 21 stops at a position separated from the upper surface of the spatula-shaped portion 11 by a predetermined distance. We must try to choose one that is strong enough.

As the restoring member 3, a known member that can obtain appropriate elasticity can be used in addition to the coil spring, a leaf spring, a rubber lump, and the like. Needless to say, it is not limited to the rear end side of each of the ear-picking main rod 1 and the slide rod 2 shown, but it is possible to select an appropriate position, for example, the front-end side or the middle of the ear-picking main rod 1 and the slide rod 2. .

[0019]

Embodiment 2 This embodiment is another embodiment characterized by the combined structure of the slide rod 2 with respect to the ear-picking main rod 1, in which the slide rod 2 is housed in the hollow portion of the ear-picking main rod 1. This is due to the structure.

The main body of the earpick main rod 1 is made of a thin hollow tube made of stainless steel, and the tip end side tube portion is cut off by about 2/3 in section and then cut off by about 45 °. The spatula-like portion 11 is formed by bending the edge to a smooth side and shaping the periphery smoothly. In addition, the front end side of the main body portion, the end portion having the pipe cross section, and the rear end are formed so that a cross section that does not interfere with the sliding of the slide rod 2 described later is drawn. In addition to safety and design considerations, the slide rod 1 has a rattling prevention structure.

The slide rod 2 is also made of stainless steel thin steel, and its tip side is bent at an angle of about 42 to 43 degrees, which is slightly smaller than the bending angle of the spatula portion of the earpick main rod 1 described above. Similarly to the first embodiment, a pressing portion 21 made of a small cocoon-shaped soft plastics material is capped and integrated at the same place, and a drop-shaped plastics operating portion 22 is formed at the rear end thereof. Is crowned and integrated. In the figure, a protruding portion 23 provided at the tip side of the slide rod 2 and a portion located inside the earpick main rod 1 has a function of hooking on the upper end of the restoring member 3 described later and receiving the restoring force of the restoring member 3. It is the part to fulfill.

The combination structure of the slide rod 2 with the ear-picking main rod 1 allows the main body of the slide rod 2 to be loosely fitted in the hollow portion 13 of the ear-picking main rod 1, and the inner tip side of the ear-picking main rod 1 and the slide rod. It is realized by interposing a coil spring, which is the restoring member 3, between the two projections 23.

[0023]

[Operation effect]

 According to the present invention having the above-described configuration, the pressing portion 21 of the slide rod 2 is arranged at a position spaced from the upper surface of the spatula-shaped portion 11 of the ear-picking main rod 1, and the operation portion 22 is operated. Since the pressing portion 21 advances to the upper surface of the spatula-shaped portion 11 to form an abutting shape, the earwax to be taken out can be gripped not in the cross-sectional direction of the ear canal but in the axial direction. , It is very convenient for ear wax removal, especially for infants who have a small ear canal.

In particular, in the structure shown in the first embodiment, the structure is such that the ear rod main rod 1 and the slide rod 2 can be easily combined with each other, so that the manufacturing is easy and the cost can be reduced. , When you do not need to operate the slide rod 2 by yourself, like when cleaning your own earwax, you can easily remove the slide rod 2 from the earpick main rod 1 narrow groove 12 to create a so-called traditional earpick. It also has the feature that it can be used and has high practical value.

In the structure shown in the second embodiment, the ear-picking main rod 1 is a hollow tubular ear-pick, which can realize ear-picking with an extremely small cross section as a whole, and ear-picking for infants having a narrow external auditory canal. It has a feature that it can be made very easy to operate.

As described above, the earwax cleaning by the earpick of the present invention may damage the outer ear canal skin as compared with the method of scraping the ear canal by scraping it and the conventional method of picking it by putting it on the tip of the earpick well. It is extremely safe and easy to clean the earwax of the baby as the mother does not have to be very careful to put it on the tip of the earpick. It will be possible.

In addition, compared to the previously proposed method of removing earwax by using an earpick that uses a pair of tweezers that open and close in the left-right direction, the earwax can be easily removed by picking even in a narrow external ear canal. It is also suitable for cleaning earwax attached to the inner part of the ear canal. In addition, since the pressing portion 21 is formed independently of the spatula-shaped portion 11, the spatula-shaped portion 11 once removes the earwax. After collecting at a convenient place in the ear canal, the operation of pressing the operation part 22 as it is, that is, without pulling out the tip of the ear scraping part, aligns the position of the pressing part 21 with the earwax, and pushes it in. The earwax can be picked up with, so as with the conventional tweezers combination type, after collecting the earwax, take out the earpick once, invert it and reinsert the tweezers side, The annoyance of having to remove earwax is eliminated all at once, making it a very convenient earpick.

The earpick of the present invention has a feature of extremely high practical value that is excellent in operability in handling, as well as a feature that is particularly excellent in safety, as in the case of a baby. It is expected that it will exert its great power as an earpick for business.
