Dual structure tpe eartip having wax guard

A dual structure thermoplastic elastomer (TPE) eartip, which is an eartip mounted on one side of an earphone and inserted into an external auditory meatus of a wearer to stably fix the position of the earphone, the dual structure TPE eartip comprising:

• a core portion (110) formed in a hollow cylindrical structure corresponding to an outer circumferential surface of one end of the earphone and configured with a TPE material having a first hardness value;
• a wax guard portion (120) formed in a plate-type structure integrally formed with an upper end of the core portion (110) and having a plurality of through-holes (123) formed therein and configured with the same material having the same hardness value as the core portion (110);
• a flange portion (130) formed in a structure continuously forming a curved structure sideward and downward in a radial shape after extending a predetermined height upward from the upper end of the core portion (110), configured with a TPE material having a second hardness value, and configured to come in contact with an inner surface of the external auditory meatus of the wearer;
• a foreign matter discharging air pump (141) mounted in a ring structure along an outer circumferential surface of the core portion (110) and configured to be elastically reduced due to being pressed from both sides by the flange portion (130) to inject air suctioned from the outside into a transfer pipe (142);
• the transfer pipe (142) formed inside the core portion (110) and configured to transfer the air transferred from the foreign matter discharging air pump (141) to a first nozzle (143) and a second nozzle (144);
• the first nozzle (143) formed as a plurality of first nozzles (143) spaced apart at predetermined angles on an inner circumferential surface of an upper portion of the core portion (110) and configured to communicate with the transfer pipe (142) and spray the air transferred from the transfer pipe (142) to a hollow space inside the core portion (110) to allow the air to flow upward through the through-holes (123) of the wax guard portion (120);
• and
• the second nozzle (144) formed inside the wax guard portion (120), formed at each of the through-holes (123), and configured to communicate with the transfer pipe (142) and spray the air transferred from the transfer pipe (142) to the through-holes (123) to allow the air to flow upward together with the air sprayed from the first nozzles (143).
