Field of the Invention

The present invention relates to the field of ear cleaning. In particular, the present invention relates to the field of safe, hygienic ear cleaning.

Background of the Invention

The ears must regularly be cleaned of excess accumulation of wax.

Cotton tips are the most common ear-cleaning devices. The shaft of the cotton-tipped stick is either plastic or wood, manufactured to uniform length and shape.

However, the ear is a delicate, intricate area, including the skin of the ear canal and particularly the myringa (eardrum). Too vigorous attention to ear cleanliness may put hearing at risk, due to injury of the myringa.

It is an object of the present invention to provide a safe ear-cleaning device for self-use.

Other objects and advantages of the invention will become apparent as the description proceeds. Summary of the Invention

Detailed Description of Preferred Embodiments

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In some instances, well-known methods, procedures, components and circuits have not been described in detail, for the sake of brevity.

FIG. 1 illustrates a device for cleaning the ear, according to one embodiment of the present invention.

An ear-cleaning device 2 includes a thimble 4 holding an appropriate wrapped cotton wad 6 for cleaning the ear.

Thimble 4 may include springy branches 48 at the bottom for grasping an inserted finger, a narrow extension head 10 at the top, and an expansion 50 in between.

FIG. 2 illustrates the device of FIG. 1, detached.

The user may detach thimble 4 from cotton stick 8 holding cotton wad 6.

Cotton stick 8 and an extension head 10 of thimble 4 fit together, and may be adjustably extracted one from the other, to enlarge or diminish the distance between cotton wad 6 and thimble 4.

FIG. 3 illustrates the adjustment of the length of the neck of the device of FIG. 1.

The term "neck", denoted by 52, will refer herein to the combination of cotton stick 8 and extension head 10 of thimble 4. According to one embodiment the force holding cotton stick 8 to extension head 10, and allowing the adjustment of the length of neck 52, may be friction force between them, provided by corresponding machining item of diameter 60 of extension head 10 and diameter 62 of cotton stick 8.

This friction force should be larger than the friction force between cotton wad 6 and the ear canal walls.

According to this embodiment, the length of neck 52 may be adjusted by simple pushing or pulling of cotton stick 8 in relation to extension head 10 of thimble 4.

According to another embodiment, cotton stick 8 and extension head 10 may have corresponding threads 56 and 54 (shown in FIG. 2) for adjusting the length of neck 52.

FIG. 4 is a sectional view of another embodiment for adjusting the length of neck 52.

Extension head 10 has several slots 42, each for a different length of neck 52. A protrusion 44 of cotton stick 8, corresponding to slots 42, may enter one of slots 42, to determine the desired length of neck 52.

FIG. 5 illustrates the first step of insertion of the device of FIG. 1 into the ear.

Finger 14 in thimble 4 pushes cotton wad 6 through entrance 12 of the ear into canal 16 thereof.

FIG. 6 illustrates the second step of insertion of the device of FIG. 1 into the ear. The term "border" refers herein to the location on thimble 4, where thimble cannot enter ear entrance 12.

Thimble 4 includes a border 58, located on expansion 50, where the width of thimble 4 is greater than ear entrance 12.

Thimble 4 functions as a guarding object, as border 58 thereof limits insertion of cotton wad 6 into ear canal 16.

The location of border 58 is fixed and not adjustable, depending on the width of ear entrance 12.

FIG. 7 illustrates the third step of insertion of the device of FIG. 1 into the ear.

For cleaning canal 16 at greater depth, the user may extend neck 52 by extracting cotton stick 8 from extension head 10, and then reinsert cotton wad 6, subject to the limitation of fixed border 58.

The term "pre-adjustment" refers herein to the adjustment of the estimated penetration depth of cotton wad 6 into canal 16 prior to ear cleaning.

Adjustment of the length of neck 52 pre-adjusts the depth of cotton wad 6 at the actual cleaning of the ear.

FIG. 8 illustrates a package for selling the device of FIG. 1.

The term "bulb" refers herein to a cotton stick 8 wrapped by a cotton wad 6.

Since cotton stick 8 may be attached and detached from thimble 4, a plurality of bulbs, each including cotton stick 8 and cotton wad 6, may be replaceable components sold in a package 64 with one thimble 4. FIG. 9 illustrates a sectional view of the structure of the cotton stick according to one embodiment.

The longitudinal external surface of cotton stick 8 may include a thread 66 or niches for industrially wrapping cotton wad 6 by spinning cotton stick 8 in relation to the cotton, such that thread 66 catches the cotton fibers, producing a wad.
