Description

A self-circulating automatic defogging protective mirror

technical field

The patent of the present invention belongs to the field of electronics, in particular to a self-circulating automatic defogging protective mirror.

Background technique

The outbreak of serious infectious diseases often brings disastrous consequences to human beings. In recent years, the epidemic outbreaks of SARS, bird flu, Ebola, etc. have seriously affected people's lives. In the fight against these diseases, some respectable medical staff are fighting on the front line. Some even gave their precious lives, so it is very important to strengthen the protection of medical personnel. Among these protective devices, eye protection is a difficult point. In the past, after using the protective goggles for a period of time, the increased sweat from the human body would blur the lenses. At this time, people would habitually wipe them with their hands, resulting in contamination of the goggles. In desperation, the World Health Organization proposed not to recommend wearing goggles, but not wearing goggles will expose the eye parts and increase the chance of infection. Therefore, the present invention proposes a self-circulating and automatic defogging protective goggles.

Contents of the invention

In order to automatically remove the sweat generated by the human body and ensure the thoroughness of the goggles, the present invention proposes an automatic defogging goggle.

The technical solution adopted by the present invention to solve its technical problems is: the device of the present invention is composed of a dried gas connection capillary, a mirror frame upper chamber, a dried gas conversion connection pipe, a dried gas output pipe, a right eyeglass leg, a right side frame chamber, and a single chip microcomputer. , temperature and humidity sensor, gas conversion tube before drying, gas output pipe before drying, left eyeglass leg, left lens, fan motor, gas connection capillary before drying, gas nozzle after drying, gas suction bucket before drying, nose bridge cavity, fan , drying chamber, left rack chamber, relay, resistor, triode, right lens, left lower rack, right lower rack. The front gas suction funnel is connected, the dried gas connection capillary is in the upper frame cavity of the frame, the dried gas output pipe is connected to the dried gas nozzle through the dried gas conversion adapter and the dried gas connection capillary, and the temperature and humidity sensor is connected to the left frame cavity The left frame cavity is connected with the left lens, the air output pipe is connected with the drying chamber through the fan before drying, the drying chamber is connected with the air output pipe after drying, the single-chip microcomputer is connected with the temperature and humidity sensor, the single-chip microcomputer is connected with the triode through a resistor, and the triode passes through The relay is connected with the fan motor; the gas nozzle is conical after drying, and the gas suction funnel is in the shape of a circular funnel before drying. The temperature and humidity sensor is located above the protective mirror. The length is less than a quarter of the length of the left lower shelf; the entire dry and humid air system forms a closed loop, that is, the gas in the automatic defogging goggles does not communicate with the outside air.

The outer gas output pipe after drying and the outer gas output pipe before drying are both rubber soft-connected cylindrical hoses, and the use of rubber hoses can be easy to wear and comfortable. The fan is connected with the fan motor. After drying, the gas nozzle is conical to facilitate the ejection of drying gas to form a certain pressure. After drying, there are multiple gas nozzles in the upper frame cavity, right frame cavity, left frame cavity, left lower frame, and right lower frame, so that the drying gas can be sprayed out evenly. Before drying, the gas suction funnel is in the shape of a round funnel to facilitate the collection of gas in the protective glasses. Before drying, the gas suction funnels are evenly distributed in the upper frame cavity, right frame cavity, left frame cavity, left lower frame, and right lower frame of the frame, so as to absorb moisture evenly.

The entire drying and humidity system forms a closed loop, that is, the gas in the automatic defogging protective mirror does not communicate with the outside air, thus ensuring no virus intrusion.

Since relative humidity is greatly affected by temperature, a temperature and humidity sensor is used as a sensor for monitoring humidity, which can take into account the influence of temperature on humidity parameters. The temperature and humidity sensor sends the signals of temperature and relative humidity to the microcontroller. At a certain temperature, when the relative humidity is higher than the limit value of the relative humidity prestored in the memory, the single-chip microcomputer sends an instruction to connect the power supply of the fan motor (13) through the resistor (22), the triode (23), and the relay (21). The fan motor (13) drives the fan to rotate, sucks the moisture added by the human body sweat in the protective glasses through the gas suction bucket (16) before drying, connects the capillary (14) through the gas before drying, the gas conversion adapter (9) before drying, and The front air outlet pipe (10) enters the drying chamber (19). The drying chamber is filled with granular desiccant. After the moisture passes through the granular desiccant, the moisture is sucked dry and becomes dry gas. The dried gas is sprayed into the protective glasses through the dried gas output pipe (4), the dried gas conversion adapter (3), the dried gas connection capillary (1), and the dried gas nozzle 15. When the relative humidity value sent by the temperature and humidity sensor into the single-chip microcomputer is lower than the limit value of the relative humidity prestored in the memory, the single-chip microcomputer sends an instruction to disconnect the fan motor (13) through the resistor (22), the triode (23), and the relay (21). power supply. Fan motor (13) stops rotating. The dehumidification process of the protective glasses is completed through the above process.

The temperature and humidity sensor (8) is located above the protective glasses, so that the relative humidity in the protective glasses can be well monitored without affecting the line of sight. The width of temperature-humidity sensor (8) is less than the width of frame cavity on the picture frame, and the length of temperature-humidity sensor (8) is less than 1/4 of the length of left lower shelf (25), otherwise it will affect the line of sight.

The beneficial effects of the present invention are that it can effectively remove sweat mist generated by human sweat, ensure that the lenses of the protective glasses are transparent, and the whole system constitutes a self-circulating system without air exchange with the outside world, ensuring that the air in the mirrors is not polluted. It is mainly used in the field of medical protection.
