Sterilizing and drying device for hearing aid

Abstract

The invention relates to a sterilizing and drying device for a hearing aid. The device comprises a shell body and a shell cover which is connected with the shell body in an opening and closing mode. The shell cover and the shell body form an accommodating cavity accommodating the hearing aid. The shell body is internally provided with a sterilizing device and a drying device. The sterilizing device comprises at least one group of first ultraviolet light tube and at least one group of second ultraviolet light tube, wherein the first ultraviolet light tube emits ultraviolet light having a wavelength of 200-280nm, and the second ultraviolet light tube emits ultraviolet light having a wavelength of 160-200nm. The drying device comprises at least two groups of heating units which work independently, wherein the heating units include heating elements, a power circuit and a main control circuit which are electrically connected with one another. The sterilizing and drying device has a dual sterilizing function, an arranged mirror reflection layer enables ultraviolet light to be directly radiated and reflected to the hearing aid, a transparent partition plate is arranged to enable the hearing aid to be under 360-degree full-range irradiation of ultraviolet light, the sterilizing and drying device has super-strong and thorough disinfection and sterilization effects under multiple actions, and constant temperature is truly achieved.

Description

technical field [0001] The invention relates to a disinfection and drying device, in particular to a disinfection and drying device for hearing aids. Background technique [0002] A hearing aid is a tool that helps people with hearing disabilities improve their hearing impairment, thereby improving their ability to communicate with others. Most of the people who wear hearing aids are elderly and disabled people. They are weak and have poor resistance. However, hearing aids are plugged in the ears for a long time. Due to the contamination of sweat and earwax, bacteria and viruses are easy to breed and endanger people. health, it is therefore of paramount importance to improve their hygiene. Moreover, hearing aids will inevitably be dampened by water vapor in the air and moisture in the ear during use. Therefore, in daily maintenance work, removing moisture is an essential measure.

Moreover, hearing aids will inevitably be dampened by water vapor in the air and moisture in the ear during use. Therefore, in daily maintenance work, removing moisture is an essential measure. For the drying of hearing aids, traditional The best method is to put the hearing aid in a container with a built-in desiccant. This drying method has the following defects: the desiccant contains carcinogenic substances, which has the potential risk of seriously damaging the health of the user; at the same time, the desiccant product contains fine debris It will enter the hearing aid and block it, affecting the service life of the hearing aid

In addition, in the field of heating and constant temperature, it is commonly used to set upper and lower limits. When the heating reaches the upper limit, stop heating, stop for a period, and start heating when the temperature drops to the lower limit. In this cycle, it is obvious that the constant temperature process is not stable. Large fluctuations, low temperature control accuracy
