Embodiment 1

[0006] Ergonomic self-fixing anti-insect earplugs are made of soft silicone. The central axis of the ear canal column (2) and the cut surface of the outer surface of the earplug (7) are 90 degrees apart. o angle. Three layers of anti-slip rings (1) arranged in a barbed shape are distributed on the outer wall of the ear canal column (2), and the inner diameter of the sound transmission hole (8) on the outer side of the earplug (7) is 0.5mm.

Embodiment 2

[0008] Ergonomic self-fixing anti-insect earplugs are made of hard sponge, the middle axis of the ear canal column (2) and the side of the earplug body (7) are 100 degrees apart. o angle. The outer wall of the ear canal column (2) is distributed with 2 layers of barb-shaped anti-slip rings (1), and the inner diameter of the sound transmission hole (8) on the outer side of the earplug (7) is 0.5mm.

[0009] When wearing, wear a pair of chiral symmetrical insect-proof earplugs on the left and right ears respectively. Insert the ear canal column (2) into the ear canal, put the earplug body (5) into the ear socket of the outer auricle, align the helix foot groove (6) with the position of the helix foot, and adjust the positions of the tragus, antitragus, and helix , so that it wraps around the four sides of the earplug body (5).

Abstract

The invention discloses a human engineering self-fixing insect prevention earplug characterized by mainly comprising an earplug body, an earplug neck and an ear canal column connected in sequence; the earplug body, the earplug neck and the ear canal column are connected through an ear canal tube, and connected with sound holes arranged on the outer side face of the earplug body; the sound is transferred into the ear canal mainly through the sound hole; the sound hole is small in inner diameter, so insects can be effectively blocked outside, thus preventing insects from entering ears without affecting sound transmission. The human engineering self-fixing insect prevention earplug can effectively prevent insects from entering the ear canal, thus effectively protecting ear canal and hearing of people having activities outdoors.

Description

technical field [0001] The field of the invention relates to a device for preventing insects from entering the ear canal, in particular to an insect-proof earplug designed according to ergonomic principles. Background technique [0002] In spring, summer, and autumn, because the temperature is suitable for the activities of insects, people who are outdoors, especially outdoor activities, are easily invaded by some small insects, such as mosquitoes, into the ear canal. The light ones bring panic and discomfort, and the severe ones can even cause inner ear damage and hearing damage. Therefore, it is very important to prevent insects from entering the ear. There is no suitable, special device to prevent insects from entering the ear in the market. Therefore, it is very necessary to develop an earplug that is specially used to prevent small insects from entering the ear. Contents of the invention [0003] The invention discloses "an ergonomic self-fixing anti-insect earplug...
