Description

Ear clip type hearing aid and charging box Technical Field The invention relates to the technical field of hearing aids, in particular to an ear clip type hearing aid and a charging box. Background Hearing aids are hearing aids which are small loudspeakers that amplify sounds that are not originally heard and then use the residual hearing of the person with hearing impairment to deliver the sounds to the brain auditory center where they are perceived. Bringing great convenience to the hearing impaired. The hearing aids are classified by way of use into cartridge type, eyeglass type, hairpin type, behind-the-ear type, in-the-canal type, and deep-the-canal type hearing aids, wherein in-the-ear type hearing aids in turn include in-the-ear clip type hearing aids. In the prior art, ear clip hearing aids can be clamped on the human ear, and then the microphone of the ear clip main body is used for picking up sound, and sound is transmitted to the human ear through a loudspeaker. However, the prior art ear clip type hearing aid has the following defects that (1) the surface of an ear clip main body of the prior art ear clip type hearing aid is harder, the elasticity is smaller, the ear clip main body is worn on a human ear for a long time, a user can feel clamping pain, wearing is uncomfortable, particularly, the ear shapes of different users are greatly different, the shape of the ear clip main body is difficult to adapt to the shape in the ear of the different users, (2) the prior art ear clip type hearing aid usually adopts an open type ear clip main body, the ear clip main body cannot be plugged into a human ear nail cavity, a sound outlet of a loudspeaker cannot directly extend into an external auditory canal of the human ear, thus the sound pickup effect of the human ear is reduced, the hearing aid is greatly reduced, the hearing aid effect is greatly reduced, the microphone of the prior art ear clip type hearing aid is not subjected to anti-noise treatment, and is easy to cause howling problem due to noise, and (4) the prior art ear clip type hearing aid is provided with parameters through an external intelligent device, a gain compensation value of the ear clip type hearing aid cannot be set through a charging box, and the battery charge box cannot display electric quantity through the charging box. Disclosure of Invention The invention aims to solve the technical problems of the prior art, provides an ear clip type hearing aid which is comfortable to wear and can be suitable for users with different ear shapes, and also provides a charging box which can adjust and display the gain compensation value of the ear clip type hearing aid and can display the electric quantity of a battery. In order to solve the first technical problem, the technical scheme of the invention is that the ear clip type hearing aid comprises a clamping unit part, an ear-in unit part and a bridge part, wherein the bridge part is connected between the clamping unit part and the ear-in unit part, the ear-in unit part comprises a hard inner shell, a silica gel outer shell and a loudspeaker, the loudspeaker is arranged in the hard inner shell, a loudspeaker sound outlet hole is formed in the front end of the hard inner shell, the sound outlet direction of the loudspeaker faces the loudspeaker sound outlet hole, the silica gel outer shell is detachably sleeved outside the hard inner shell, a first through hole corresponding to the loudspeaker sound outlet hole is formed in the front end of the silica gel outer shell, and a gap space is reserved between the silica gel outer shell and the hard inner shell, so that the silica gel outer shell forms a silica gel air bag outside the hard inner shell. The technical scheme has the beneficial effects that the ear-in unit part comprises the hard inner shell and the silica gel outer shell, the silica gel outer shell is detachably sleeved outside the hard inner shell, and a clearance space is formed between the silica gel outer shell and the hard inner shell, so that the silica gel outer shell forms the silica gel air bag outside the hard inner shell, and the wearing comfort of a user can be improved by utilizing the material softness of the silica gel air bag on one hand; on the other hand, the silica gel air bag can be utilized to enable different positions of the silica gel outer shell to be capable of being compressed and deformed inwards or outwards and deformed outwards, the pressing elasticity of the silica gel outer shell can be remarkably improved, users with different ear shapes can be adapted after deformation, on the other hand, the silica gel outer shell adopts a detachable structure, and when the old silica gel outer shell is damaged, a new silica gel outer shell can be directly replaced outside the hard inner shell. According to the invention, the loudspeaker is arranged in the hard inner shell, the front end of the hard inner shell is provided with the loudspeaker sound outlet hole, th
