The present invention relates to thermometers, and particularly for you to some display assembly of having a digital thermometer, wherein the actuation of backlight plate was designed to reduce the power lose so so that you may prolong the duration of the thermometer.
To achieve above objects, the present invention provides an exhibit assembly of an electronic thermometer which comprises: a heat sensor, a display unit, a backlight plate, and a processor; wherein the heat sensor measures temperature; after measurement of temperature, if it is detected that the temperature is decreased, the processor will actuate the backlight plate for illuminating the display watch. The display unit displays measured temperature values after measurement of temperature. Quick reading . unit is actuated with the backlight plate for displaying the measuring data. A buzzer is installed in the thermometer, after measurement of temperature, the buzzer will emit sound. The processor can de-actuate automatically. The thermometer has an adjustment solution.
In both systems, the thermistor probe controls a Wheatstone bridge which produces an analog signal when the thermistor probe causes the bridge to become unbalanced from a null point the thermistor in the probe senses a specific temperature. The analog signal from the bridge is developed into digital signals are usually processed to control an appropriate temperature reading display.
The electronic digital thermometer of the present invention is constructed in a manner such that along with the relatively inexpensive stable resistors in the bridge, highly accurate temperature readings can be obtained, thereby obviating the need for expensive high precision resistors in the bridge such as required by the first sort art high accuracy electronic digital thermometers.
In at least one prior art thermometer, a backlight plate is installed at a backside of the display program. When the temperature is measured, the backlight plate will light upwards of illuminate the display unit so your user can watch the heat level. When the measurement of temperature is complete, the backlight plate will illumine automatically. However, the period after measurement of temperature and before taking out the thermometer will induce the undesired power waste due to the power lose from the backlight menu.
Accordingly, key object of this present invention is to supply a display assembly of an electronic thermometer, wherein the actuation of backlight plate was created to reduce the capacity loss with the intention to prolong the lifetime with the thermometer.
The present invention is thus described, it become obvious how the same can be varied often. Such variations aren't to be regarded like a departure inside spirit and scope belonging to the present invention, and these modifications as would be obvious to skilled regarding art are intended to be included within the scope for the following lawsuits.
