Problems solved by technology

[0005] The purpose of the present invention is to overcome the existing decompression earplugs, which have poor decompression effect and affect hearing and other deficiencies, and provide a cushioning decompression earplug, which can not only effectively block the air pressure difference, but also disregard the eustachian Whether the tube is smooth or not, it can play a role in decompression. Its biggest advantage is that it can play the role of two-way decompression buffer, so no matter when the external air pressure increases or decreases sharply, it can protect the ears well and protect us. hearing loss

Embodiment Construction

[0019] An embodiment of the present invention is described in detail as follows in conjunction with accompanying drawing:

[0020] see Figure 1 to Figure 6 , a cushioning and decompression earplug, comprising a rubber sealing ring 1, a sleeve 2, a filter screen 3 and a light elastic ball 4; the rubber sealing ring 1 is arranged outside the two ends of the sleeve 2 to prevent external air from entering the ear In the tunnel, the filter screen 3 is arranged at the two ends and the middle part of the inner side of the sleeve pipe 2, and several light elastic balls 4 are arranged in the interval of the three filter screens 3, and the filter screen 3 in the middle can move left and right.

[0021] The filter screen 3 is provided with several mesh holes, and the diameter of the mesh holes is smaller than the diameter of the light elastic ball 4 .

[0022] From Figure 7 It can be seen from the figure that when the air pressure of the external auditory canal increases sharply, a p...

Abstract

The invention relates to a buffering and pressure reduction earplug which comprises rubber sealing rings, a sleeve, filter nets and a plurality of small light elastic balls. The rubber sealing rings are arranged on the outer sides of the two ends of the sleeve. External air is prevented from entering the auditory meatus. The filter nets are arranged at the two ends and the middle of the inner side of the sleeve. The multiple small light elastic balls are arranged at the intervals between every two of the three filter nets. The middle filter net can move leftwards and rightwards. The buffering and pressure reduction earplug can well protect the hearing organ against influences of ambient pressure changes on the condition that the audition is not affected, and the wide application prospect and obvious economic effects are achieved.

Description

technical field [0001] The invention belongs to the technical field of ear structure protection, in particular to a cushioning and decompression earplug. Background technique [0002] With the take-off or landing of the plane, the diving or ascent of the diver, and the impact of the explosion, the air pressure outside the ear will change drastically, which will have different degrees of impact on the tympanic membrane, middle ear, and inner ear. Tinnitus, in severe cases, can cause perforation of the tympanic membrane, damage to the ossicular chain, and damage to the inner ear, thereby affecting hearing. [0003] When the pressure outside the ear changes sharply, because the eustachian tube is not opened in time or the ventilation is poor, the tympanic membrane is compressed and invaginated, and the ossicular chain ligament is tensed. If the pressure is too large, the ligament may be damaged or broken, and even lead to Ossicle fracture. [0004] At present, there are alrea...
