DETAILED DESCRIPTION

[0026] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are used only for explaining the present application, and cannot be understood as a limitation of the present application.

[0027] The embodiments of the present application are described below in conjunction with Figures 1 to 7 , a earplug and a hearing aid earphone.

[0028] Referring to Figures 1-5 , the earplug of the present application comprises a connecting cylinder 1, a flexible sealing ring 2 and a baffle 3, a plurality of flexible sealing rings 2 are sleeved on the connecting cylinder 1, the baffle 3 is located at the top end of the connecting cylinder 1, and the baffle 3 is provided with a plurality of through holes 31.

[0029] The connecting cylinder 1, the flexible sealing ring 2 and the baffle 3 are of an integral molding structure, and the outer wall of the flexible sealing ring 2 at the top end of the connecting cylinder 1 is smoothly connected with the top surface of the baffle 3.

[0030] In the technical solution, the baffle 3 with the through holes 31 blocks the sound outlet of the connecting cylinder 1, which can isolate earwax and prevent earwax from entering the earplug 5, and also ensure the sound effect. The earplug 01 is prepared by an integral molding method, which simplifies the production process and reduces the product cost. Moreover, the integral molding structure of the connecting cylinder 1, the flexible sealing ring 2 and the baffle 3 makes the earplug structure reliable. Specifically, the wall surface of the flexible sealing ring 2 is arc-shaped, so that the flexible sealing ring 2 is in the shape of an umbrella or a mushroom head with a hole in the center, thereby making the flexible sealing ring 2 fit the ear canal to achieve a sealing effect.

[0031] Further, the connecting cylinder 1, the flexible sealing ring 2 and the baffle 3 are made of silica gel material. The earplug made of silica gel material has skin-friendly property, and based on the flexible characteristics of silica gel, the top end of the connecting cylinder 1 and the baffle 3 can be set to a larger size to improve the sound effect.

[0032] Preferably, the number of through holes 31 of the baffle 3 is greater than or equal to 3, and the diameter of the through holes 31 is less than 2mm. By limiting the number of through holes 31 on the baffle 3, the sound quality is ensured while achieving the effect of preventing earwax.

[0033] Referring to Figure 2 In an embodiment of the present application, the inner wall of the connecting cylinder 1 is provided with a plurality of anti-skid rings 11. When the earplug is installed on the hearing aid 02, the bottom end of the connecting cylinder 1 is sleeved on the earplug head 5 of the hearing aid, and the anti-skid rings 11 provided on the inner wall of the connecting cylinder 1 improve the stability of the earplug installed on the hearing aid 02. Figure 4 In another embodiment, the wall thickness of the bottom end of the connecting cylinder 1 is greater than the wall thickness of the upper part of the connecting cylinder 1, and the outer wall of the connecting cylinder 1 is a smooth wall surface. By increasing the wall thickness of the connecting cylinder 1, the difficulty of deformation of the bottom end of the connecting cylinder 1 is increased, and after the bottom end of the connecting cylinder 1 is sleeved on the earplug head 5 of the hearing aid, the bottom end of the connecting cylinder 1 can more firmly cover the earplug head 5, thereby improving the connection firmness.

[0034] Referring to Figure 5 In order to achieve the effect of removing dirt, in an embodiment of the present application, the connecting cylinder 1 is provided with a flexible expansion part 12, and pressing the flexible expansion part 12 generates airflow to dredge the through hole 31. The wall thickness of the flexible expansion part 12 of the connecting cylinder 1 is small, so that it has flexibility and can be deformed. When the through hole 31 on the baffle 3 is blocked, an instantaneous airflow is generated by pressing the flexible expansion part to impact the through hole 31 and blow out the dirt in the through hole 31. This dirt removal method is convenient to operate and makes the earplug structure simple, and the earplug can still be made in an integral molding manner. It can be understood that the diameter of the flexible expansion part 12 is smaller than the diameter of the flexible sealing ring 2 to ensure the sealing effect when the earplug is worn.

[0035] Further, the lower part of the flexible expansion part 12 is provided with a plurality of blocking parts 13, and the flexible expansion part 12 has gaps between the plurality of blocking parts 13 in a natural state. When the expansion part is pressed, the plurality of blocking parts 13 close the sound outlet channel of the connecting cylinder 1, so that more gas impacts the baffle 3, thereby achieving a better defogging effect. Correspondingly, the blocking part 13, the flexible sealing ring 2, the connecting cylinder 1 and the baffle 3 are an integral molding silicone product. Preferably, the blocking part 13 is in the form of a sheet. The blocking part 13 is preferably three.

[0036] Correspondingly, the present application also provides a hearing aid 02, which comprises an earphone body 4, an earplug head 5 and the above-mentioned anti-earwax earplug 01. The earplug head 5 is connected to the earphone body 4 through a connecting line, and the connecting cylinder 1 of the anti-earwax earplug 01 is sleeved on the earplug head 5. The baffle 3 on the anti-earwax earplug 01 can block earwax, prevent earwax from entering the earplug head 5 through the earplug, and ensure that the hearing aid 02 can work normally.

[0037] Further, the earplug head 5 is provided with a connecting column 6, and the connecting barrel 1 of the earplug 01 is sleeved on the connecting column 6; and the top end of the connecting column 6 is provided with a metal mesh. The metal mesh is used for further preventing dirt and scale.
