Abstract

The utility model relates to a minitype anit-myopia device which is a minitype electronic product used for reminding children to maintain correct pose when reading and writing, and is particularly suitable for solving the problem that a device for deaf-mute children to prevent acquired myopia and humpback is lack. The utility model comprises a base and a box-shaped housing embedded with a cover, and is characterized in that the housing is provided with a hook, the shape of the housing can be made into a pen shape, all pendants and the like so as to be convenient for students to carry, the housing is internally provided with a circuit board, the circuit board is provided with a vibration circuit which comprises a battery, the power supply loop of the circuit is connected with a power supply switch (K1) and an angle mercoid switch (K2) in series, the output power loop of the circuit is connected with a shaking collection block (H1), a current-limiting adjustable resistance (R) and a shaker (s). The students sometimes look the head down too lower without attention when reading or doing housework at the table, at this time, the student can use the product, the utility model can automatically send reminding signal, when the students look the head up, the reminding signals can automatically stop.

Description

A kind of miniature myopia prevention device

Technical field:

The miniature myopia prevention device a kind of easy to carry and use that the utility model relates to.Be the miniature electronic product that keeps correct posture when being used to remind children's reading and writing, be specially adapted to solve the problem that deaf and dumb children prevent that acquired myopia and bow-backed utensil lack.

Background technology:

Correct student's reading and writing posture apparatus and generally be more common in the mechanical type retainer, its defective is that volume is bigger, occupies studying space, and it is not quite convenient to use; Also have some myopia prevention electronic products to pay attention to sound and light signal, influence other classmate's study but existed last class hour to use, use, then can cause the disorder sight of class as the fruit part classmate, other classmate's protest or oppositions will inevitably be caused, even teacher's prevention can be suffered; Simultaneously, there is the dead angle in this product, can not be used in deaf and dumb children, feel to observe world's learning knowledge owing to they can only rely on, so their prevent acquired myopia and hunchback then more seems particularly important.

Summary of the invention:

The utility model purpose provides a kind of miniature myopia prevention device; the student makes every effort on one's body can be worn over very easily; the student bows when writing reading; the eye distance books are crossed when closely surpassing the proper angle of determining; make the utility model can send an amount of vibration signal automatically; remind the student to correct posture at once, correct the back vibration signal and stop immediately, thereby play the effect that the protection eyes prevent acquired myopia.

Technical scheme: a kind of miniature myopia prevention device of the utility model, comprise by base and cover the chimeric cassette shell that constitutes, it is characterized in that: have the hook that is used for housing is worn on student's chest that is cemented in outside the housing, hull shape can be made the form of a stroke or a combination of strokes, various suspension members etc.Have circuit board and circuit board in the housing and be provided with the vibrations circuit, this circuit includes by battery, is in series with battery main switch (K in its current supply circuit ₁) and angle mercury cut-off (K ₂), it is exported and is connected with vibrations integrated package (H), current limliting adjustable resistance (R) and electromagnetic shaker (s) in the electric loop.

Beneficial effect: the utility model purpose purpose is when the serious hunchback of sitting posture of student or bows when playing some prank or other, send vibration signal immediately, remind the student to correct faulty sitting posture, note paying attention to the class, thereby help the student conscientiously to listen to the teacher, prevent hunchback, assurance student body normal development growth.Particularly national now advocating strengthened student's physical exercise, builds up health, and cultivates the qualified talent of modernization construction, and the especially suitable market demand that then seems is released on this product ground, thereby has the wide development prospect.

Description of drawings:

Accompanying drawing 1 is the structural representation of a kind of miniature myopia prevention device of the utility model.

Accompanying drawing 2 is the organigram of vibrations circuit among a kind of miniature myopia prevention device Fig. 1 of the utility model.

Embodiment:

Below in conjunction with accompanying drawing the embodiment that a kind of miniature myopia prevention device of the utility model provides is further described.Referring to Fig. 1, base and lid that this myopia prevention device includes plastic production lean on the housing (1) of the chimeric formation of elasticity of plastics, and the outer rim of housing (1) is consolidated with hook (2), and hull shape can be made the form of a stroke or a combination of strokes, various suspension members etc.Housing has circuit board in (1), and circuit board is provided with circuit, and it is constructed as shown in Figure 2.Battery main switch (K is arranged ₁), angle mercury cut-off (K ₂) and adjustable resistance (R).The characteristics 1 of this circuit are: adopted master switch (K ₁) and angle mercury cut-off (K ₂) unitized construction, master switch (K ₁) setting have power saving effect, promptly in that the time spent is not placed on then angle mercury cut-off (K of closed condition ₂) no matter be that this myopia prevention device of on-off is not all worked; And the control user bow angle, keep correct figure to adopt the special miniature angle mercury cut-off (K of high sensitivity ₂) make the characteristics highly sensitive, reliable operation that the utlity model has.Characteristics 2 are: be provided with electromagnetic shaker current limliting adjustable resistance (R) in circuit, vibration signal can artificially be adjusted in effectively have only oneself to experience and degree that other people are difficult for feeling, play the effect of leaving other people alone.

Claims

1. miniature myopia prevention device comprises by base and covers the chimeric cassette shell that constitutes that characteristics are to have hook on the housing; Hull shape can be made the form of a stroke or a combination of strokes, has circuit board in the housing, and circuit board is provided with the vibrations circuit, and this circuit includes battery, is in series with battery main switch (K in its current supply circuit ₁) and angle mercury cut-off (K ₂), it is exported and is connected with vibrations integrated package (H), current limliting adjustable resistance (R) and electromagnetic shaker (s) in the electric loop.
