Problems solved by technology

However, the price of a 3D printer is not cheap, ranging from tens of thousands to hundreds of thousands of yuan. The shells produced are not necessarily better than those made by hand. The cost of 3D printers that introduce advanced foreign technology is quite huge, and it is not the first choice for most domestic hearing aid sellers. In contrast, more domestic earphone or hearing aid sellers still use purely manual production methods

Embodiment 1

[0029] figure 1 and figure 2 It schematically shows an ear canal shape modeling device according to an embodiment of the present invention.

[0030] refer to figure 1 and figure 2 The ear canal shape modeling device includes a closed chamber 1, a lifting mechanism 2, an ear sample female mold 3, an ultraviolet lamp 4, a spraying system 5, a female mold container 6, a mirror reflector 7 and a control system 8. The spraying system 5 sprays the atomized photosensitive nano raw materials into the ear-like female mold 3 to form a film, and then irradiates with the ultraviolet lamp 4 to harden the film into a hearing aid shell with a shell structure. The invention provides a fast and efficient production equipment for the production of the custom shell of the hearing aid.

[0031] The ear sample female mold 3, the female mold container 6 and the ultraviolet lamp 4 are all located in the airtight chamber 1, and the airtight chamber 1 is provided with a door that can be opened a...

Embodiment 2

[0037] image 3 It schematically shows an ear canal shape modeling device according to another embodiment of the present invention.

[0038] refer to image 3 The ear canal shape modeling device includes a closed chamber 1, a lifting mechanism 2, an ear-like female mold 3, an ultraviolet lamp 4, a spraying system 5, a female mold container 6 and a control system 8. The spraying system 5 sprays the atomized photosensitive nano raw materials into the ear-like female mold 3 to form a film, and then irradiates with the ultraviolet lamp 4 to harden the film into a hearing aid shell with a shell structure.

[0039] The ear sample female mold 3, the ultraviolet lamp 4, and the female mold container 6 are all located in the airtight chamber 1, and the airtight chamber 1 is provided with a chamber door that can be opened and closed, so that the ear sample can be put into or taken out of the airtight chamber 1 Female mold 3 and female mold container 6. The ear sample female mold 3 is...

Embodiment 3

[0045] Figure 4 Schematically shows a process flow chart of a method for manufacturing ear canal shape modeling according to an embodiment of the present invention.

[0046] refer to Figure 4 , the manufacturing method of ear canal shape modeling, comprises the following steps:

[0047] S1. Making ear-like female mold 3:

[0048] 1.1 Obtain the shape of the user's external auditory canal and make a positive mold; inject the mixture of A and B glues into the user's external auditory canal at the same time, mix the A and B glues and cure them at room temperature for 2-5 minutes, and then take out the cured colloid from the user's ear canal to obtain the same An ear mold with the same shape as the ear canal, that is, a "male mold". Then, according to the volume of the earphone chip, speaker, microphone and other units, the male mold is cut and modified to ensure the beautiful appearance of the post-production earphones.

[0049] 1.2 Stir water and gypsum powder into a paste...

Abstract

An ear canal form model manufacturing apparatus, comprising a sealed chamber (1), an ear-like female mold (3), an ultraviolet lamp (4), and a spraying system (5). The ear-like female mold (3) and the ultraviolet lamp (4) are both located in the sealed chamber (1). The spraying system (5) comprises an atomizing spray head (51), and the atomizing spray head (51) can extend into or leave the ear-like female mold (3). The manufacturing method comprises the following steps: S1: manufacturing an ear-like female mold (3), and fixing the ear-like female mold (3) in a sealed chamber (1); S2: spraying a photosensitive nano-raw material into the ear-like female mold (3); S3: illuminating and curing the sprayed raw material by means of an ultraviolet lamp (4); S4: taking out a shell to obtain a finished product. The present invention provides an apparatus and method capable of efficiently making an ultra-thin shell.

Description

technical field [0001] The invention relates to a manufacturing device and a manufacturing method of a hearing aid shell, in particular to a manufacturing device and method for modeling the shape of an ear canal. Background technique [0002] With the improvement of people's health awareness and quality of life, more and more people use various earphones to listen to music, and people with hearing impairment are also willing to accept the use of hearing aids to improve audibility and clarity. And with a more concealed appearance, the shells of earphones or hearing aids need to be customized according to the shape of the user's ear canal. These shells are called customized shells, and then chips, microphones, speakers and other components are embedded in the shells to make format earphones or in-ear devices such as hearing aids. During the entire customization process, the production of the shell is very particular, because it directly affects the wearing comfort and listeni...
