A ring shape a ball an use a sleepiness a prevention a device}

The present invention relates to a drowsiness preventing device for preventing a user's drowsiness, in particular, when the user is drowsy often detects this when the head part shakes before, after, or left and right according to the drowsiness habits to generate a warning sound, etc. It relates to a drowsiness prevention device using an annular ball sensor for preventing the user from drowsiness through the warning.

In general, drowsiness refers to a phenomenon in which the mind and body are mostly relaxed due to lack of sleep or fatigue, which is a warning message and a physiological phenomenon indicating that the body has reached the limit of physical strength or mental power.

Therefore, this drowsiness is a phenomenon in which the mind and the body are relaxed, and the body is loosened due to the relaxation of the body. As a very natural phenomenon, most people have to go through this process without knowing themselves when they are sleeping. This is difficult to control, and in most cases it is most desirable to relieve the fatigue accumulated in the body.

However, it is extremely rare to get sleep because of the drowsiness of everyday life, and there are many situations in daily life that should not be drowsy.

For example, most safety accidents caused by industrial sites using large work machines such as press working and forging work are often caused by drowsiness of workers. There are a lot of people who are struggling with drowsiness.

Therefore, in order to alleviate the inconvenience of these users, techniques for preventing drowsiness have been proposed. The techniques proposed in the prior art generally operate when the user falls asleep while falling asleep and the pupil of the user's eyes. It can be distinguished by the way it works by detecting changes.

In this case, the latter method of detecting the user's pupil change is configured to operate by detecting the phenomenon that the pupil shrinks when the user is drowsiness and the blink of the eye, the detection method is complicated, the unit price is high, the user actually There is a problem that is uncomfortable.

In addition, structurally, when the device is installed according to the corresponding method, since there is a fundamental problem that the range of detecting a change in the pupil of the user is extremely limited, there is a limitation that its use is followed.

In addition to the above-described method of detecting a change in the pupil, a representative prior art of a method of detecting a warning by shaking the head when the user tightens, as described in Korean Patent Application No. 27185 No. 27185, Due to the user's price, the price is competitive.

Referring to the attached prior art described above with reference to FIGS. 1 and 2, in a manner of implementing an independent drowsiness preventer having an inner phone shape inserted into the ear, FIG. 1 is an exemplary configuration of an insert-type drowsiness preventer. Figure 2 is a perspective view showing an embodiment of a sensitive switch of the configuration suitable for the ear insertion type drowsiness prevention.

As shown in the accompanying FIG. 1, the drowsiness preventer 1 has a front accommodating portion 20 having an insertion portion 1 ′ into the front ear and a rear accommodating the circuit board 2 therein. It is composed of an injection molded body or the like which can sandwich the accommodating portion 21. Between the front accommodating portion 20 and the rear accommodating portion 21, an approximately circular thin circuit board 2 is embedded and the circuit board 2 ), All the members are assembled and received.

In the front of the circuit board 2, a conventional magnetic speaker, a crystal speaker, etc., which is miniaturized, the speaker unit 3 is fixed, and in the rear, a speaker 4, a ball inclination switch 30, a mercury cell 5 are fixed. And a switch 6 are mounted.

The operation principle can be seen by looking at the operation of the ball inclination-angle sensitive switch 30 shown in Figure 2 attached, the ball inclination-angle sensitive switch 30 is the head of the operator with respect to the mounting reference line (G) more than a predetermined inclination angle For example, as shown in FIG. 2, a metal sensing ball 32 is accommodated inside an insulating tube 31 such as glass or plastic, and a pair is provided at one end thereof as a switch means for sensitizing and vocalizing when the inclination becomes inclined. When the user feels that the sensitive terminal piece 33 is fixed to the upright straight, when the sensitive ball 32 rolls along the insulated tube 31 and touches the wound terminal piece 33, it electrically conducts to generate a warning sound through the speaker. It is to be made.

The prior art for detecting the shaking of the user's head is only possible in spite of the user's tightening because the user's head can only operate when the user's head is shaken in a direction corresponding to the mounting reference line G. ) Has a limitation that it can't warn because the shake is not in that direction.

In addition, the gyro sensor to detect the shaking of the head in a manner proposed to overcome the problems of the prior art shown in Figures 1 to 2 attached in the manner of detecting the shaking of the head The scope sensor may be used, but it is a very expensive part, and this also includes technical limitations that the above-described problem is maintained because the shaking of the head cannot be detected in all 360 ° directions.

An object of the present invention proposed to solve the above problems relates to a drowsiness preventing device for preventing a user's drowsiness, in particular, when the user is sleepy, if the head part is shaken before, after or left and right according to the drowsiness habits The present invention provides a drowsiness prevention device using an annular ball sensor for preventing the user from drowsiness through warning such as generating a warning sound by detecting this.
