Abstract

The utility model discloses an electronic digit display thermometer with Chinese speech sounding, comprising a casing, a sensing head, a thermocouple connected with the sensing head, an amplifying circuit connected with the output end of the thermocouple, and a liquid crystal display chip connected with the output end of the amplifying circuit. The utility model is characterized in that the thermometer also comprises a Chinese speech chip connected with the output end of the amplifying circuit. The speech chip adopts the HY12503 programmable advanced speech chip. The utility model has the advantages of high precision of temperature measurement; the minimum resolution is 0.1 DEG C and the utility model can measure the temperature under dark condition; the utility model is especially suitable for blind and old people and the temperature measurement has a short time which is only 50 seconds.

Description

Warm clinical thermometer reported in electronic digital display Chinese

The utility model relates to a kind of medical apparatus, particularly relates to the clinical thermometer that can survey body temperature.

Measure body temperature at present, modal is to adopt the glass mercury clinical thermometer, has occurred the liquid crystal display electron clinical thermometer in recent years again.These two kinds of clinical thermometers all need at bright place eyes careful survey, just can read the body temperature that shows on the clinical thermometer, this is very inconvenient for survey body temperature under dark condition, and the elderly, child or disabled person, the particularly blind person body temperature of testing oneself is all had certain difficulty.

The purpose of this utility model is to provide a kind of and can reads automatically and show the body temperature temperature, and easy to use, is suitable for the electronic digital display Chinese that the elderly, child or disabled person use and reports warm clinical thermometer.

The purpose of this utility model by following measure this to: it comprises shell, sensing head, the amplifying circuit that joins with the responsive thermopair that joins, with the thermopair output terminal, the chip of LCD that is connected on amplification circuit output end, and its characteristics are: also comprise the Chinese speech chip that is connected on amplification circuit output end.After sensing head is experienced temperature, by thermopair temperature transition is become electric weight, amplifying circuit amplifies the output of coding back with this electric weight, on the one hand by the LCD panel displays temperature, on the other hand digital quantity is imported the Chinese speech chip, after deciphering, quoted relevant temperature by Yang Shengqi.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a structural front view of the present utility model;

Fig. 2 is a LCD plate synoptic diagram in the rear view of the present utility model;

Fig. 3 is an electrical schematic diagram of the present utility model;

Fig. 4 is the electrical schematic diagram of the utility model Chinese speech chip.

Referring to accompanying drawing 1,2, the thermopair 3 that present embodiment joins by shell 1, sensing head 2, with quick head, the amplifying circuit 4 that is connected on thermopair 3 output terminals, the LCD plate 5 of joining with amplifying circuit 4 ends, form with LCD plate 5 and the Chinese speech chip 6 that connects, Microspeaker 7 and power supply 8.

Referring to accompanying drawing 3,4, integrated amplifier 6 is that the output signal of IC1 is sent into chip of LCD 5 respectively and Chinese speech chip 6 is IC2, IC2 adopts general HY12503 programmable advanced speech chip, it comprises address/data/shift register 61, clock generator 62, voice POM PROM array voice operation demonstrator 63, D/A converter 64, program and logic function controller 65,3V, 1.5V voltage stabilizer and supply power soft switch 66, wherein 1-18 is the address strobe end, 19-20 is 1.5V voltage stabilizer and supply power soft switch, 24-26 temperature voice output trigger end, 25-26 is the 3V power input, 27-28 clock crystal line end.

The utility model compared with prior art has following advantage:

1. owing to adopt the Chinese speech chip, so the temperature measurement accuracy height, minimum resolution is 0.1 ℃.

2. also observable temperature under dark condition is fit to disabled person, especially blind person, the elderly very much Use.

3. thermometric time weak point only needs 50 seconds.

4. thermometric is convenient, and waterproof, anti-shaking.

Claims

1. warm clinical thermometer reported in an electronic digital display Chinese, it comprises shell, sensing head, the amplifying circuit that joins with the responsive thermopair that joins, with the thermopair output terminal, the LCD plate that is connected on amplification circuit output end, and its characteristics are: also comprise the Chinese speech chip that is connected on amplification circuit output end.

2. warm clinical thermometer reported in electronic digital display Chinese according to claim 1, it is characterized in that: what the Chinese speech chip adopted is HY12503 programmable speech chip.
