DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] Regarding the detailed content and structural means of present invention, please refer to the description of the diagrams as follows:

[0028] Referring to FIG. 1, which shows an earplug with enhanced wearing comfortability of the present invention, wherein an earplug 10 comprises a main guide body 20, a supporting stem 30, and a filler material 40.

[0029] The main guide body 20 further comprises a guide portion 21, a compression portion 22 that extends from the guide portion 21, and a stop portion 23 that extends from the compression portion 22, all arranged in an axial configuration. The exterior of the guide portion 21 assumes an umbrella form, and a connecting cavity 24 is provided inside the guide portion 21. A filling cavity 25 is provided inside the compression portion 22, the exterior of the stop portion 23 assumes an umbrella form, and an opening portion 26 is provided inside the stop portion 23. The filling cavity 25 interconnects the connecting cavity 24 and the opening portion 26.

[0030] The supporting stem 30 that extends along the same axial direction as the main guide body 20 is provided with a connecting section 31 that enables embedding into the connecting cavity 24, an extended section 32 that extends from the connecting section 31 and is positioned inside the filling cavity 25, and a securing section 33 that extends from the extended section 32 and embeds within the opening portion 26. Moreover, the securing section 33 is provided with an air passage 34, which enables air to pass therethrough (not shown in the drawing) and circulate between the exterior of the main guide body 20 and the interior of the filling cavity 25. In addition, a holding section 35 further extends outward to the exterior of the main guide body 20 from the securing section 33.

[0031] The filler material 40 is provided with plasticity and fills the interior of the filling cavity 25 to enable an air chamber 27 to form therein and contain air. Air can enter the air chamber 27 through the air passage 34 for the compression portion 22 to maintain an original state.

[0032] Referring further to FIGS. 2 to 6, which show a second embodiment aspect of the earplug 10, and in this embodiment a compression portion 22 further comprises a first compression area 221 that extends from a guide portion 21 and a second compression area 222 that extends from the first compression area 221.

[0033] The second compression area 222 is connected to a stop portion 23, and a filling cavity 25 further comprises a first filling cavity 251 that is positioned inside the first compression area 221 and a second filling cavity 252 that is positioned inside the second compression area 222, wherein a passage cavity 253 provides interconnection between the first filling cavity 251 and the second filling cavity 252. The diameter of the passage cavity 253 is smaller than the diameters of both the first filling cavity 251 and the second filling cavity 252, and the diameter of the first filling cavity 251 is slightly smaller than that of the second filling cavity 252. The second filling cavity 252 is connected to an opening portion 26, and a filler material 40 respectively fills the first filling cavity 251, the passage cavity 253, and the interior of the second filling cavity 252. Moreover, an air chamber 27 is positioned inside the second filling cavity 252 and connects to an air passage 34.

[0034] It is worth mentioning that the filler material 40 in the second embodiment is formed from silicone material, and the silicone filler material 40 is first heated to form a liquid, after which the liquid silicone material is injected into the interior of the main guide body 20. It is important to explain that the liquid silicone material does not completely fill the interior of the second filling cavity 252 when injecting the liquid silicone material into the interior of the main guide body 20. After injecting the liquid silicone material, the supporting stem 30 is disposed into the interior of the main guide body 20 before the liquid silicone material has cooled down to enable inserting and embedding a connecting section 31 of the supporting stem 30 into a connecting cavity 24 while enabling an extended section 32 to extend into the filling cavity 25.

[0035] In addition, an embedding structure 50 is further configured between a securing section 33 and the opening portion 26, wherein the embedding structure 50 comprises: a first embedding portion 51 positioned at the opening portion 26 and a second embedding portion 52 positioned on the securing section 33 and embedded into the first embedding portion 51. Accordingly, when the supporting stem 30 is disposed into the interior of the main guide body 20, apart from embedding the connecting section 31 into the connecting cavity 24, the supporting stem 30 is also embedded into the opening portion 26 by means of the securing section 33, thereby enabling the supporting stem 30 to effectively embed into the main guide body 20 and preventing separation from occurring between the supporting stem 30 and the main guide body 20.

[0036] After disposing the supporting stem 30 into the interior of the main guide body 20, a silicone material is caused to solidify inside the filling cavity 25 and form the filler material 40 using a cooling or photocuring method, which also causes the air chamber 27 to form within the second filling cavity 252, thereby enabling air to pass through the air passage 34 on the supporting stem 30 from the exterior of the main guide body 20 and enter the air chamber 27, which further enables the compression portion 22 to maintain its original state.

[0037] Referring to FIGS. 5 to 7, when an earplug 10 is inserted inside a person's ear canal 60, it is of prime importance to first use the guide portion 21 to enter the person's ear canal 60, which is followed by the compression portion 22 gradually coming into contact with the interior of the person's ear canal 60, whereupon the ear wall presses against the compression portion 22 causing deformation thereof and compression of the filler material 40 within the filling cavity 25. And because the filler material 40 is provided with plasticity, thus, the filler material 40 also deforms within the filling cavity 25. After deforming, the filler material 40 produces a pushing force toward the air chamber 27 that squeezes and expels the air therein to the exterior of the main guide body 20 through the air passage 34, thereby causing the compression portion 22 to form a compressed state and enabling the stop portion 23 to block the entrance area of the person's ear canal 60. Accordingly, apart from enabling the compression portion 22 to produce a more favorable contact effect with the person's ear canal 60, the earplug 10 achieves better airtightness within the person's ear canal 60. In addition, compression of the compression portion 22 by the person's ear canal 60 compresses the filler material 40, which then squeezes and expels the air out to effectively reduce the pressure within the earplug 10, thereby enhancing comfortability when wearing the earplug 10.

[0038] On the contrary, when the earplug 10 is gradually separated from the person's ear canal 60, the pressure produced by the ear wall on the compression portion 22 also gradually decreases along with a correspondingly gradual decrease in the pushing force of the filler material 40 on the air, at which time the pressure within the air chamber 27 is less than the atmospheric pressure outside the person's ear canal 60, which causes air to gradually enter the air chamber 27 through the air passage 34 and compress the filler material 40 until the earplug 10 is completely separated from the person's ear canal 60, whereupon the filler material 40 continues to be compressed by the air, causing the compression portion 22 to return to its original state from a compressed state, thereby further providing the earplug 10 with the effect of reusability and substantially extending the serviceable life thereof.

[0039] It is worth mentioning that it is of prime importance to hold a holding section 35 of the supporting stem 30 when inserting/extracting the earplug 10 into/out of the person's ear canal 60 to ensure added convenience when carrying out insertion or extraction of the earplug 10.

[0040] It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
