Abstract
The utility model relates to a digital display thermometer quartz clock technological board, formed by that the surrounding of the utility model is provided with a frame, one side of the frame is a quartz clock, another side is a digital display thermometer whose surrounding is provided with luminous diodes, the front of the quartz clock and the digital display thermometer is a transparent glass plate, and the back of the quartz clock is a cover plate. The digital display thermometer is controlled by a circuit, temperature is converted to voltage by a temperature sensor of the circuit, the voltage is imported into an A/D converter, the voltage is converted to digital by the A/D converter, and the temperature is displayed by a digitron composed of the luminous diodes under the drive of a driving circuit. The utility model has the double functions of time displaying and temperature displaying. The utility model is suitable for civilians, having certain decorative performance as used in public places, and the price is low.
Description
The utility model is to have temperature display function and the digital display thermometer crystal clock Artist horizontal inscribed board of function when apparent for what ground such as public place, factory floor or family used.
At present used digital display thermometer and quartz analog clock all are separately to use, and are not one, and it all is to use charactron that the numeral of digital display thermometer shows, its price is more expensive, increased user's burden, and this digital display thermometer all is industrial, can not be used for civilian.
The purpose of this utility model is to overcome present digital display thermometer, and the weak point of quartz analog clock provides a kind of existing temperature display function, again the digital display thermometer crystal clock Artist horizontal inscribed board of free Presentation Function.
The utility model is achieved through the following technical solutions, around the digital display thermometer crystal clock Artist horizontal inscribed board is framework, a side is a quartz analog clock in the framework, opposite side is a digital display thermometer, around the digital display thermometer is light emitting diode, and the front of quartz analog clock and digital display thermometer is transparent flat glass, and the back is a cover plate, the numeral of digital display thermometer shows that using light emitting diode, temperature displayed is that radix point Celsius back keeps one digit number.Digital display thermometer is controlled by circuit, has adopted temperature sensor in circuit, by sensor temperature transition is become analog quantity---and voltage is input to 1/2 A/D converter of CMOS3 to voltage.A/D converter gets analog quantity and converts digital quantity to, and the charactron of forming through overdrive circuit driving electroluminescent diode comes the displays temperature value again.Light emitting diode around the digital display thermometer is controlled by programme control circut that it is program control luminous.
The utility model and separate at present the digital display thermometer that uses, electronic quartz clock mutually this, have existing function when apparent, temperature display function is arranged again, cheap advantage is suitable for civilianly, use also has certain decoration function in public places.
Accompanying drawing 1 is a structural representation of the present utility model, and Fig. 2 is the A-A cut-open view of Fig. 1.Among the figure 1---framework; 2---crystal clock; 3---charactron; 4---light emitting diode; 5---cover plate; 6---panel; 7---flat glass.
In force, framework can be made by aluminium alloy, and also available common wood or redwood are made, and are made as the best with the aluminium gold alloy.Distance between each light emitting diode on the charactron of being made up of light emitting diode is good with the 5-10 millimeter, and in manufacturing process, digital display thermometer must be through metering, to guarantee the accuracy of its displays temperature value.
Claims (3)
1, a kind of digital display thermometer crystal clock Artist horizontal inscribed board is a framework around it is characterized in that, a side is a quartz analog clock in the framework, opposite side is a digital display thermometer, around the digital display thermometer is light emitting diode, and the front of quartz analog clock and digital display thermometer is transparent flat glass, and the back is a cover plate.
