Refrigeration refresher

Abstract

The invention discloses a refrigeration refresher. The refresher comprises a semiconductor refrigeration sheet, wherein the semiconductor refrigeration sheet is connected with a refrigeration driving control device electrically; a cold end of the semiconductor refrigeration sheet is provided with a temperature conducting sheet which is in contact with human bodies directly, and a hot end of the semiconductor refrigeration sheet is provided with a heat radiating device; the refrigeration refresher also comprises a buzzing reminding device; after the refresher is energized, under the driving control of the refrigeration driving control device, the cold end of the semiconductor refrigeration sheet can reach a set temperature rapidly, and when a human body is in contact with the temperature conducting sheet, a refreshing effect is achieved by a cold stimulation nerve; and the buzzing reminding device can remind of a user of touching the temperature conducting sheet timely, the user is not required to touch the temperature conducting sheet all the time, a user also is not required to remember the time when to touch the temperature conducting sheet, the good refreshing effect is achieved, and burden for the user is avoided at the same time.

Description

Technical field [0001] The invention relates to a refreshing device, and also to a refreshing device suitable for motor vehicle drivers. Background technique [0002] Some sleepy reminders on the market are warning devices that are worn on the ears and use the working principle of electronic balance. By detecting the regulator, the amplitude of the person's head is measured (under normal circumstances, the head is not more than 30 degrees), and it monitors the person's sitting posture , When a person bows his head too much, an alarm will sound to stimulate the central nervous system and eliminate drowsiness. However, this device has the following disadvantages: first, the user must wear it all the time, and a heavy object hanging on the ear for a long time will cause a burden to the person, and it is more likely to cause annoying emotions; , This device is tested for sleepiness through the angle of the person's head down. Only when people are deeply sleepy will they have a large...

AI Technical Summary

Problems solved by technology

But this device has the following defects: the first, the user must wear it all the time, and hanging a heavy object on the ear for a long time will cause a kind of burden to the people, and it is easier to make people feel irritable; , this device is to test people's drowsiness through the angle of people's head bowing. People will only bow their heads at a large angle when they are deeply dozing off. It cannot prevent people from being reminded when they are slightly drowsy, so the sensitivity is not high; If you lower your head by more than 30 degrees, it is easy to cause misoperation and trigger the alarm sound; fourth, the sound may not wake you up when you are dozing off, because you can sleep even if you are trapped under loud noise, and you should The device also alarms after detecting that people are drowsy, which is an after-the-fact action. The time after the setting may have caused danger. For example, an accident will be caused in just a few milliseconds during driving, so the existence cannot really refresh people and The problem of insufficient safety and reliability

There is also a microcomputer refresher, which uses the refresher to be worn on the wrist. If the wrist stops moving for 10 to 15 seconds, it is determined that the person is dozing off, and then the device emits a high-voltage electric pulse to stimulate the person or activates a vibrating micromotor to remind. The disadvantages of this kind of setting are: first, stabbing people with high-voltage electric pulses, although the power is not enough to damage the human body, but ordinary people have a fear of electricity, so it will give users resistance; second , the human body is stimulated by electrical pulses, and the nerves of the human body are also relatively complicated. Especially if it is worn on the wrist, the electrical pulses that may be generated may stimulate a certain nerve in the human body, which will prompt human hands to malfunction. The steering wheel causes danger; third, the vibration power of the micro-motor equipped with the device is too small, and the slight vibration on the arm of the person is not enough to wake up the drowsy person; fourth, the device comes when the person does not move the wrist for 10-15 seconds It is not scientific enough to judge people falling asleep. Sometimes people do not fall asleep but their wrists stop for more than 10-15 seconds and cause false movements. Some people really doze off for such a long time before they are reminded that there is a phenomenon of lagging behind, which is dangerous during driving.

Therefore, there are defects of not being timely and not having high precision
