A kind of toothbrush and its implementation of being carried out interaction by projectionTechnical field
The present invention relates to interactive motion type toothbrush art, particularly relate to a kind of toothbrush and its implementation of being carried out interaction by projection, by the detection of brushing action and shadow casting technique are combined, good interaction effect is provided, promote the interest of user of toothbrushing, encourage the tooth-brushing habit that user keeps fit.
Background technology
The current more existing toothbrush with interaction function on the market, especially for the toothbrush for children of child, is generally carry out interaction by sound, indicator lamp or display screen and user, wishes the interest being guided user of toothbrushing by these modes.
Above-mentioned existing interaction mode because transmit information content very few and single, can make user use a period of time after just interaction is lost interest, be therefore difficult to the object reaching design.In addition, the display due to information is on toothbrush body, so user is inconvenient to see when brushing teeth, this is unfavorable for effective interaction equally.
Summary of the invention
In order to solve the deficiencies in the prior art, the present invention proposes a kind of toothbrush and its implementation of being carried out interaction by projection.
And in order to solve the problems of the technologies described above, technical scheme of the present invention is as follows:
Carry out an interactive toothbrush by projection, be made up of head toothbrushes and toothbrush handle, toothbrush handle outer wall is provided with switch, is provided with power supply in toothbrush handle.Power supply, motion sensor, drive circuit, control circuit and projecting cell is contained in the inside of toothbrush handle.Wherein, power supply connects with control circuit; Control circuit connects with motion sensor, drive circuit, projecting cell; Drive circuit connects with projecting cell.
Switch includes but not limited to mechanical switch and action induction switch.
The opening and closing of power supply to control circuit control, control circuit can execution inductor, drive circuit, projecting cell management, wherein, motion sensor induction brushing action, drive circuit carries out image projection for driving projecting cell.Control drive circuit by control circuit, can be carried out the projection of various image by projecting cell, such as progress displaying bar, countdown, tooth profile, brushing result evaluation, projection are reminded.
Projecting cell comprises light emitting diode matrix, transmissive display, set of lenses.Light emitting diode matrix can be that the combination of multiple white light-emitting diode is formed, and also can be that the multiple different monochromatic light emitting diode combined can releasing white light is formed.Projecting cell sends collimated light beam by light emitting diode matrix and is irradiated in transmissive display, and transmissive display adopts waterproof transmissive design.The pattern scioptics group of transmissive display display projects away.In order to adapt to different perspective planes, set of lenses can be preset as and project to infinity.
Wherein, adopt light emitting diode matrix as backlight, volume can be reduced, reduce power consumption.Toothbrush needs the information of display to be shown by transmissive display.
Projecting cell can also adopt the mode of reflection.Projecting cell comprises light emitting diode matrix, polarization splitting prism, transmissive display, set of lenses.Light emitting diode matrix can be that the combination of multiple white light-emitting diode is formed, and also can be that the multiple different monochromatic light emitting diode combined can releasing white light is formed.
The light that light source sends, by after polarization splitting prism, is irradiated in transmissive display.Transmissive display display needs the information of projection, and the while that light being reflected rear, polarization direction is changed, and be polarized the reflective surface of Amici prism to set of lenses, set of lenses goes out image projection.Wherein, in order to adapt to different perspective planes, set of lenses can be preset as and project to infinity.
In order to better drop shadow effect, polarizer can be increased to reach better effect at light source place and transmissive display place.
Carried out an implementation method for interactive toothbrush by projection, comprise the following steps.
Step one, user brings into use toothbrush, and by switch open power supply, control circuit opens projecting cell by drive circuit 1.
Step 2, after user starts to brush teeth, motion sensor starts to catch the dynamics and the brushing action such as direction of brushing teeth of brushing teeth, and show brushing location, and reminding user will brush the enough time by projecting cell.Which region the exhibition method of projecting cell can brush by the skeleton pattern prompting user showing tooth, also by more succinct mode, can replace tooth model with the circle of four sections.In addition, projecting cell is by the mode reminding user brushing time of progress bar and countdown.
Step 3, is divided into four regions tooth: left outside, left inside, right outside, right inside, can learn whether user has brushed corresponding region by the feedback data analyzing motion sensor.In addition, also have a kind of easier implementation to be the progress bar and countdown that are shown by projecting cell, allow user oneself the assurance time.After user has brushed a region, projecting cell is progress displaying bar and countdown again, and the next region of reminding user brush, until brushed teeth.
Step 4, sets the brushing action standard of respective action inductor in advance, in the process of brushing teeth, when the action of discovery user of toothbrushing is inaccurate, then by projecting cell reminding user.
Step 5, after user of toothbrushing, whether amplitude region that is whether enough, that brush teeth that is whether enough based on brushing time, that brush teeth all covers, and the standards the such as whether dynamics of brushing teeth is suitable, evaluate the brushing condition of user, brushing condition is shown by projecting cell.
In above-mentioned steps, projecting cell is projected by light emitting diode matrix, transmissive display, set of lenses.Wherein, light emitting diode matrix can be that the combination of multiple white light-emitting diode is formed, and also can be that the multiple different monochromatic light emitting diode combined can releasing white light is formed.Projecting cell sends collimated light beam by light emitting diode matrix and is irradiated in transmissive display, and transmissive display adopts waterproof transmissive design.The pattern scioptics group of transmissive display display projects away.In order to adapt to different perspective planes, set of lenses can be preset as and project to infinity.
In above-mentioned steps, projecting cell can also carry out reflective projection by light emitting diode matrix, polarization splitting prism, transmissive display, set of lenses.The light that light source sends, by after polarization splitting prism, is irradiated in transmissive display.Transmissive display display needs the information of projection, and the while that light being reflected rear, polarization direction is changed, and be polarized the reflective surface of Amici prism to set of lenses, set of lenses goes out image projection.Wherein, in order to adapt to different perspective planes, set of lenses can be preset as and project to infinity.Wherein, in order to better drop shadow effect, polarizer can be increased to reach better effect at light source place and transmissive display place.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
Of the present invention by more cheap, compact projection arrangement is integrated in toothbrush, by the action feedback of giving user interesting, real-time of low cost, reach the effect of cultivating good tooth-brushing habit.The present invention changes the display mode of interactive information, and provide the interaction content of more diversification, can effective information be provided to point out when user of toothbrushing, increase the interest of brushing teeth, promote the continuation of user interest, and then more effectively form good tooth-brushing habit, especially more there is remarkable result to the cultivation that the healthy living of children is accustomed to.
