Abstract
The utility model discloses an inverse timing device for tooth brushing, which is mainly composed of a casing, a single chip microprocessor arranged in the casing, a crystal oscillator, a set of indicator lights, a power supply and a switch. The crystal oscillator and a set of indicator lights are connected with the single chip microprocessor. The single chip microprocessor is connected with the power supply by the switch. The crystal oscillator sends out reference time signals after frequency division treating. The indicator lights are controlled by the single chip microprocessor to individually switch on the power supply and radiate in scheduled time for warning people to accurately control the tooth brushing time. The utility model has advantages of reasonable design, simple structure, convenient operation and no adjusting needs and can be used by only loading two NO. 5 batteries. The utility model is convenient for users to accurately control the tooth brushing time and make good tooth brushing habits and methods, which is beneficial to health.
Description
Technical field
The utility model relates to a kind of countdown device of brushing teeth, and refers in particular to the countdown device that a kind of people of helping cultivate correct tooth-brushing habit.
Background technology
Eating a piece may need only one minute, if but brushing time is one minute, and will not reach cleaning teeth and kill the purpose of oral cavity germ.Brushing time will have two minutes at least.In the motion that takes care of one's teeth that Japan Department of Public Health initiates, pay attention to abundant brushing time especially, because have only suitable brushing time could eliminate the gums inflammation.Current research shows that the science brushing time should be 2 minutes, firmly 150 restrains.Brushing time is long, firmly excessive, can't make tooth cleaner, but may damage the diaphragm of tooth on the contrary, brings permanent damage to tooth.Brush teeth and to adopt perpendicular brush method, when promptly brushing teeth, brush from top to bottom; During the brush lower tooth, brush from the bottom up.The outside surface of not only will brushing teeth, also the inboard that will brush teeth and mesion so just can play the effect of comprehensive cleaning teeth.
Want the health care, oral cavity cleaning, killing pathogenic bacteria are important rings, and Here it is more early begins to take care of one's teeth, with regard to GPRS correct method for brushing teeth and brushing time.
Countdown device ready-made on the market is many, but, also there is not a kind of countdown device that is specially adapted for brushing teeth, there is following disappearance in these ready-made countdown devices if be used to the timing of brushing teeth:
One, ready-made countdown device adopts the white and black displays screen mostly, and is not directly perceived during use;
Two, ready-made countdown device is not not-time at oral health specially, uses inconvenient yet.
Therefore, when people brush teeth, can only come the control time with sensation usually, brushing time control is inaccurate, can't form good method for brushing teeth and custom, is unfavorable for health.
The utility model content
The purpose of this utility model is to provide a kind of countdown device of brushing teeth, so that toothbrushing person is accurately controlled brushing time, forms good method for brushing teeth and custom, helps health.
For reaching above-mentioned purpose, solution of the present utility model is:
The countdown device of brushing teeth, mainly form by casing and chip microprocessor, crystal oscillator, one group of pilot lamp, power supply, switch of being arranged in the casing, crystal oscillator and one group of pilot lamp connect with chip microprocessor, chip microprocessor connects with power supply by switch, crystal oscillator carries out the frequency division processing and provides signal reference time, energized is luminous at the fixed time one by one to control this group pilot lamp by chip microprocessor, looks toothbrushing person with the police and accurately controls brushing time.
Above-mentioned chip microprocessor also connects with loudspeaker, and chip microprocessor is handled signal reference time that provides according to the crystal oscillator frequency division, the energized work in the given time of control loudspeaker.
Above-mentioned chip microprocessor also with a quiet key connecting, by the outage of chip microprocessor control loudspeaker.
After adopting said structure, during the utility model work, press the beginning switch earlier, the chip microprocessor program of bringing into operation that is triggered, crystal oscillator carries out frequency division to be handled, every interval provided signal reference time in 15 seconds, chip microprocessor is luminous according to the corresponding pilot lamp energized of signal controlling reference time, loudspeaker send prompt tone simultaneously, after whole (9) pilot lamp are luminous one by one, can control all pilot lamp flickers three times by chip microprocessor again, or send melodious musical sound simultaneously, return to battery saving mode then.When if the user does not need prompt tone and musical sound, only need press quiet key, this device will only provide luminous timed cue function, and forbid the output of sound.
Like this, this device is reasonable in design, simple in structure, and is easy to operate, need not to adjust, as long as behind No. seven batteries of two joints of packing into, can come into operation, greatly facilitates toothbrushing person and accurately controls brushing time, forms good method for brushing teeth and custom, more helps health.
Description of drawings
Fig. 1 is an electrical block diagram of the present utility model.
Embodiment
See also shown in Figure 1, the countdown device of brushing teeth that the utility model discloses, mainly by casing and be arranged on chip microprocessor 1 in the casing, crystal oscillator 2, one group of pilot lamp 3, power supply 4, switch 5 are formed.
Wherein, the model of chip microprocessor 1 is QA640257.Carry out frequency division and handle the 13rd, 14 pin that the crystal oscillator 2 that provides signal reference time is connected on chip microprocessor 1; One group of pilot lamp 3 comprises 9 LED, LED1-5 is connected on respectively between the collector of the 28-24 pin of chip microprocessor 1 and triode Q1, LED6-9 is connected on respectively between the collector of the 28-25 pin of chip microprocessor 1 and triode Q2, the base stage of triode Q1, Q2 is connected on the 23rd, 22 pin of chip microprocessor 1 respectively, the emitter of triode Q1, Q2 all is connected on the 21st pin of chip microprocessor 1, and LED1-9 also can otherwise be connected on the chip microprocessor 1; The 1st pin of chip microprocessor 1 connects power supply 4, and switch 5 is connected on the 1st, 6 pin of chip microprocessor 1; Loudspeaker 6 are connected on the 7th, 8 pin of chip microprocessor 1; Quiet key 7 is connected on the 1st, 5 pin of chip microprocessor 1.
Like this, during the utility model work, press beginning switch 5 earlier, chip microprocessor 1 program of bringing into operation that is triggered, crystal oscillator 2 carries out frequency division to be handled, best brushing time was divided into eight equal parts in 2 minutes, every interval provided signal reference time in 15 seconds, energized 4 is luminous one by one according to the corresponding pilot lamp 3 of signal controlling reference time for chip microprocessor 1, control loudspeaker 6 simultaneously and send prompt tone, thus, the prompting toothbrushing person is accurately controlled brushing time, be particularly suitable for the child and form good method for brushing teeth and custom when brushing teeth, more help health in just.
The utility model also can be glimmered three times by all pilot lamp of chip microprocessor 1 control, or send melodious musical sound simultaneously after whole (9) pilot lamp 3 be luminous one by one again, returns to battery saving mode then, to promote the prompting effect.
When if the user does not need prompt tone and musical sound, only need press quiet key 7, make device that luminous timed cue function will only be provided, and forbid the output of sound.
This device is reasonable in design, simple in structure, and is easy to operate, can directly need not to adjust after setting brushing time on the product again, as long as pack into behind No. seven batteries of two joints, can come into operation, replenish the blank of the current special-purpose countdown device of brushing teeth, be a kind of brand-new daily oral cavity companion.
