The main body 102, top section 104, and bottom section 106 may in some examples be made from molded plastic. In other examples, the main body 102, top section 104, and bottom section 106 may be made from metal or wood.
Referring to FIGS. 3 and 4, the toothbrush holder 100 is configured to measure the approximate duration of tooth brushing, to aid a user in determining if the teeth have been brushed for a desired amount of time. Specifically, in the example shown, the toothbrush holder 100 includes a display 118 that may indicate to a user any of the following example information: (i) the approximate length of time for which they have been brushing their teeth; (ii) for how much approximate additional time they should brush their teeth; (iii) approximately when they should stop brushing their teeth; and/or (iv) approximately when they should move their toothbrush from one section of the mouth to another section of the mouth. In the example shown, the display 118 is triggered automatically upon removal of a toothbrush from the toothbrush holder 100. Specifically, the main body includes a toothbrush removal sensor 120 (also referred to as sensor 120) positioned to detect removal of a toothbrush from the toothbrush holder 100 and issuing a removal signal in response to the removal of the toothbrush; a timer 122 initiating a time count when the removal signal is issued by the toothbrush removal sensor 120; and the display 118, which is provided on the main body 102 and displays an indicia 124 of the time count.
Referring still to FIGS. 3 and 4, in the example shown, the toothbrush removal sensor 120 is provided on an interior surface of the sidewall 108, and is housed in a compartment 121 formed integrally with the sidewall 108. As stated above, the toothbrush removal sensor 120 detects removal of the toothbrush from the toothbrush holder 100, and issues a removal signal in response to the removal of the toothbrush. The toothbrush removal sensor 120 may include, for example, a pressure sensor, a motion sensor, a reed switch and/or an RFID sensor. Alternatively or additionally, the toothbrush removal sensor 120 may include a mechanical switch.
The toothbrush removal sensor 120 may be configured to detect removal of only one of the toothbrushes that may be received in the main body 102, or may be configured to detect removal of any of the toothbrushes that may be received in the main body 102. Alternatively, a plurality of toothbrush removal sensors may be provided, and each sensor may be configured to detect removal of one of the toothbrushes.
The toothbrush removal sensor 120 is connected to the timer 122. As stated above, the timer 122 initiates a time count when the removal signal is issued by the toothbrush removal sensor 120.
In some examples, the timer 122 is provided with a preset time, or a plurality of preset times. For example, the timer 122 may be a microprocessor, which may be programmed with one or more preset times. The timer 122 may be configured send a command to the display 118 or take another action when one of the preset times is reached. For example, the timer 122 may issue an audio signal when one of the preset times is reached. Alternatively, the timer 122 may send a command to the display 118 to display an indicia of the time count when one of the preset times is reached, as will be described in further detail below. In other examples, the timer 122 may not be provided with a plurality of preset times. For example, the timer may simply initiate the time count, and may continue the time count until the toothbrush is replaced in the holder 100. In such examples, the display may simply display a continuous time readout corresponding to the time count.
In examples wherein the toothbrush holder 100 is configured to hold more than one toothbrush, the timer 122 can be configured to initiate a time count when only one of the toothbrushes is removed from the toothbrush holder 100. Alternatively, the timer can be configured to re-initiate the time count each time a toothbrush is removed from the toothbrush holder. Alternatively, as stated above, a plurality of sensors may be provided, and a plurality of timers may be provided (one for each sensor). Each timer may initiate a time count when one of the toothbrushes is removed from the holder 100.
As stated above, the display 118 displays an indicia 124 of the time count, for example upon commencement of the time count. The display may be, for example, a liquid crystal display (LCD), a light emitting diode (LED) display, or a vacuum fluorescent display (VFD).
As stated above, in some examples, the indicia 124 may be a time readout corresponding to the time count. For example, the display 118 may display the number of seconds elapsed since a toothbrush was removed from the toothbrush holder 100.
In other examples, as shown in FIGS. 1 and 2, the indicia 124 may be a countdown time readout 125. For example, the timer 122 may be programmed with a preset start time, such as of 2 minutes, and upon removal of the toothbrush from the toothbrush holder 100, the display 118 may display a numeric countdown from 2 minutes.
In other examples, the indicia 124 may comprise an icon or a plurality of icons, and an illumination level of the icon(s) may be changed when the time count reaches a preset time. For example, the timer 122 may be programmed with a preset time, and when the time count reaches the preset time, a particular icon may be lit. In one particular example, the timer may be pre-programmed with a preset time, such as a time of 2 minutes, and when the time count reaches two minutes, a happy-face icon 126 may be lit, as shown in FIGS. 1 and 2, to indicate to the user that the teeth have been brushed for a suitable amount of time. In an alternative example, a particular icon may be darkened rather than lit when the preset time is reached
In another example, the indicia may comprise an image of a mouth having four quadrants 128a-d, as shown in FIGS. 1 and 2. The timer 122 may be programmed with four different preset times, and the level of illumination of one of the four quadrants 128a-d may be changed when the time count reaches each of the preset times, to indicate to the user that a particular quadrant of the mouth has been brushed for a suitable amount of time, and the user may begin brushing a different quadrant of the mouth. For example, the timer 122 may be programmed with preset times of 30 seconds, 60 seconds, 90 seconds, and 120 seconds. Quadrant 128a may be lit when the time count reaches 30 seconds, quadrant 128b may be lit when the time count reaches 60 seconds, quadrant 128c may be lit when the time count reaches 90 seconds, and quadrant 128d may be lit when the time count reaches 120 seconds. In addition, an audio signal may be issued at each of the preset times.
In the above examples, a preset time of 2 minutes has been used. This time is but one example of a preset time, and various other preset times could be used.
Referring still to FIG. 3, in the example shown, a battery 130 is provided in the main body 102 for powering the timer 122, the display 118, and optionally the sensor 120. The battery 130 is housed in compartment 121.
