The utility model relates to an earplug device, which comprises a central column and a first umbrella wing.The central column comprises a hand-held section and a core rod section formed at one end of the hand-held section.The first umbrella wing comprises an inner end edge which is far away from the hand-held section and is connected with the core rod section in a circle, an outer end edge which is adjacent to the hand-held section and is separated with the core rod section alternately around the periphery of the core rod section, and an outer peripheral surface which is connected with the inner end edge and the outer end edge. The outer peripheral surface has several first groove parts which are angular apart from each other, and each first groove part is from the inner end edge to the outer end edge The direction of the outer end edge extends, and the inner end edge is communicated without the outer end edge.When inserting into the ear, the air in the ear can flow out of the ear through the first groove part by the design of the first groove part, so as to maintain the balance of the ear pressure in the ear without being stuffy, so that the first wing can be tightly inserted into the ear without being pushed back and dropped by the air pressure, thus having excellent usability.一種耳塞裝置，包含一支中心柱，及一個第一傘翼。該中心柱包括一個手持段，及一個形成於該手持段之一端的芯桿段。該第一傘翼包括一個遠離該手持段且圈圍連接該芯桿段的內端緣、一個鄰近該手持段且與該芯桿段相間隔地圍繞於該芯桿段外圍的外端緣，及一個連接該內端緣與該外端緣的外周面，該外周面具有數個彼此角度間隔的第一溝槽部，每一個第一溝槽部由該內端緣往該外端緣的方向延伸，且連通該內端緣而不連通該外端緣。在塞入耳朵時，能藉由該等第一溝槽部的設計，使得耳內的空氣通過該等第一溝槽部流出耳外，保持耳內的耳壓平衡而不會氣悶，以便於該第一傘翼緊密地塞入耳內且不致被氣壓反推掉落，可具有優良的使用性。
