Description

  The present invention relates to an earwax aspirator nozzle that is used to remove earwax and clean the ear canal.

  In general, when cleaning the earwax, a “cotton swab” in which absorbent cotton is wrapped around the tip or a “small earpick” with a small insulator shape is used. However, when removing the earwax using such a tool, there is a risk that the ear canal may be damaged or the eardrum behind the ear may be damaged accidentally as a result of rubbing the ear canal with a relatively hard object.

  Therefore, in recent years, an earwax aspirator for sucking earwax has been used. This earwax aspirator is a rigid resin aspirator body containing a motor and a fan, with a small-diameter suction pipe portion protruding integrally.

Since this suction tube is made of hard material and dangerous to insert into the ear hole, a nozzle 6 for earwax aspirator as shown in FIG. 7 is used. The suction nozzle 6 is a molded product of a soft synthetic resin, and one end portion side of the tube-shaped main body is set as a large-diameter mounting tube portion 61 and the other end portion side is set as a small-diameter suction tube portion 62.

In use, the large-diameter mounting cylinder portion 61 is fitted into the suction tube portion of the aspirator body, and the suction cylinder portion 62 is inserted into the ear hole. By turning on the power supply of the aspirator main body, the earwax (a secretion of the ear canal gland, the peeled epidermis) accumulated in the ear hole is sucked from the opening end of the suction tube portion 62.

  The nozzle for the earwax aspirator is an extremely soft tube-like nozzle and does not need to scrape the earwax by rubbing the ear canal strongly. Accordingly, there is no risk of damaging the inside of the ear hole, but the tube-shaped nozzle is extremely soft, so it has the disadvantage that it breaks during use and the suction effect is reduced.

  Furthermore, earwax has individual differences in properties. For example, a dry grayish white dry type (powder ear) or a wet and sticky wet type (skin ear) is known. The conventional earwax aspirator nozzle has the disadvantage that it can easily suck dry floating powder ears, but cannot absorb the ears stuck to the ear canal.

  The present invention provides a nozzle for an earwax aspirator that can solve the above-mentioned problems, can softly and does not fold down, and can safely and hygienically absorb dry earwax as well as wet earwax. For the purpose.

  In order to achieve this object, the earwax aspirator nozzle of the present invention has the following configuration.

  The earwax aspirator nozzle is a soft tube-shaped nozzle that has one end side as a large-diameter mounting cylinder part that fits into the suction tube part of the aspirator body and the other end side as a small-diameter suction cylinder part that is inserted into the ear hole. A soft gear-like earwax scraping portion comprising a plurality of teeth having a predetermined length is provided on the outer peripheral surface on the distal end side of the suction tube portion.

  In this device, as described above, since the soft gear-shaped ear wax scraping portion comprising a plurality of teeth having a predetermined length is arranged on the outer peripheral surface of the small diameter suction tube portion of the soft tube-shaped nozzle, the ear wax scraping portion is Reinforcing rib effect that prevents the nozzle (suction cylinder) from bending is exhibited. Therefore, it is possible to eliminate the disadvantages such as the suction cylinder portion being folded back during use and the suction effect being lowered as in the prior art.

  Further, the soft suction tube portion easily sucks the earwax (dry earwax) located in an opposing manner in the ear hole. In addition, by rotating the earwax scraping part in the left-right direction, the wet (waxed ear) earwax with the top of each soft tooth of the earwax scraping part sticking to the ear canal can be safely detached from the ear canal wall. .

  In addition, the dissociated (dropped) earwax, as with dry earwax, moves the suction cylinder part back and forth slightly and opposes the earwax, thereby sucking the earwax from the open end of the suction cylinder part. Thus, it can be retained in the dust collecting case on the side of the main body of the suction device that communicates.

  Furthermore, since each tooth of the gear-shaped ear wax scraping portion is set to have a gradient inclined downward toward the rear (base end) side, the ear wax scraped and dropped onto the gear-shaped scraping portion is the back of the ear ( As a result, the eardrum is scraped to the side of the ear hole that is easy to remove.

  In addition, each tooth of the gear-shaped ear wax scraping portion has long teeth and short teeth alternately arranged, and a large open space is provided between the proximal ends of adjacent long teeth, so that the tooth gap between each tooth The earwax fitted in is excellent in achieving the devised purpose, such as being able to be easily taken out from this empty space.

Hereinafter, specific embodiments of the earwax aspirator nozzle according to the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a nozzle for an earwax aspirator.

  The earwax aspirator nozzle 2 is formed into a tube shape with a soft synthetic material such as a thermosetting resin (rubber-like silicon resin / silicon rubber) or a thermoplastic material (polyethylene, polypropylene, etc.).

  The nozzle 2 has a large-diameter mounting cylinder portion 21 on one end side from the center portion of a relatively short tube body and a small-diameter suction cylinder portion 22 on the other end side.

  As shown in FIGS. 2 and 3, the nozzle 2 is attached to the earwax aspirator body 3. The aspirator body 3 is formed by integrally projecting a head 3B including a motor 31, a fan 32, and a filter 33 at the upper end of a grip 3A containing a battery 34, and an opening surface (filter) of the head 3B. 33, a cap-shaped dust collecting case 4 provided with a suction pipe portion 41 projecting from the projecting surface) is detachably attached.

The base end (rear end) of the large-diameter mounting cylinder portion 21 of the nozzle 2 is externally fitted to the suction pipe portion 41 so that the nozzle through-hole 2A and the dust collecting case 4 are communicated with each other. As shown in FIG. 4, the suction cylinder portion 22 is inserted into the ear hole, and the sucked ear wax 7 is retained in the dust collecting case 4.
The feature of this device is that a soft gear-shaped ear wax scraping portion 1 having a certain length is provided on the outer peripheral surface of the distal end side of the suction tube portion 22.

  In the embodiment, the earwax scraping portion 1 is formed as a soft resin molded product that is integral with the nozzle 2, and is, for example, a gear shape (spur gear shape) composed of eight teeth, and a plurality of long teeth 1A and a plurality of teeth. It consists of short teeth 1B.

  Each tooth (long tooth 1A, short tooth 1B) is formed in a gradient shape in which the cross section having a predetermined length is triangular, the tooth tip 11 is high and the tooth base 12 is low. . Accordingly, the apex side portion 16 of each tooth is set so as to incline downward (base end side).

  Further, the long teeth 1A and the short teeth 1B are alternately arranged in a state where the surfaces of the tooth tip portions 11 are aligned on the same line. Therefore, on the proximal end side of each tooth, a large open space portion 13 is provided between the proximal end portions 12 and 12 of the adjacent long teeth 1A and 1A.

  In the earwax aspirator nozzle having such a configuration, as shown in FIG. 4, the nozzle 2 is attached to the suction tube portion 41 of the aspirator body 3, and the nozzle (suction tube portion 22) 2 is inserted into the ear hole. When the suction operation of the aspirator body 3 is started, the earwax 7 located at the opening end surface of the suction cylinder portion 22 is sucked.

  On the other hand, for the wet earwax stuck to the ear canal, the nozzle (suction cylinder 22) is rotated in the left-right direction. As a result, the tooth crest portion 16 of each tooth of the gear-shaped ear wax scraping portion 1 on the outer peripheral surface of the suction cylinder portion 22 is peeled off by applying a rubbing operation to the wet ear wax 7 at an angle.

The peeled earwax 7 is located on the upper surface of the gear-like earwax scraped portion (long / short tooth 1A / 1B) 1. Each tooth 1A, 1B is inclined downward and backward. Therefore, the earwax 7 is guided to the entrance side of the ear canal rather than the front of the ear canal, that is, the eardrum side behind the ear, and can be easily sucked (removed).
On the other hand, when the peeled earwax 7 is located in the tooth gap portion 17 between the teeth, it can be easily discharged from the open space 13 between the adjacent long teeth 1A, 1A. Thus, the ear wax can be cleaned cleanly and safely with a simple operation, and the ear canal can be kept clean.

  FIG. 5 is a perspective view showing an example in which the present nozzle 2 is implemented in an earwax aspirator of a type in which the aspirator body 3 incorporating the dust collection case portion and the suction tube portion 41 are separate bodies.

  The aspirator body 3 communicates with the operation gripping portion 36 through a long tube 35, and a suction pipe portion 41 projects from the operation gripping portion 36. The nozzle 2 is used by being fitted to the suction pipe portion 41. In this case, since the operation gripping portion 36 is small, it is easy to perform a delicate back-and-forth movement operation and rotation operation of the nozzle 2 in the ear hole.

FIG. 6 is a perspective view showing another embodiment of the gear-shaped ear wax scraping portion 1.
In the previous embodiment, an example in which the earwax scraping portion 1 has a so-called spur gear shape is shown. However, in this embodiment, a so-called helical gear shape in which teeth are set obliquely with respect to the shaft is used. It consists of a helical tooth 14a and a short helical tooth 14b. In this case, as the teeth are inclined, the rotation with respect to the ear canal becomes smoother, and the rubbing pressure against the sticking earwax increases, so that the scraping effect is further improved.
