The electrothermometer comprises a meter body; the head portion of the meter body is provided with a temperature sensor; the tail portion of the meter body is provided with a back cover; the surface of the meter body is provided with a display screen; a microprocessor, an RC oscillator and a power supply are arranged in the meter body; the temperature sensor is connected with the input terminal of the microprocessor, detects the temperature of a heat source and transmits the detected temperature to the microprocessor, and the microprocessor determines whether triggering temperature measure operation by processing; the power supply is connected with the microprocessor to supply power for the microprocessor and all electric components; the RC oscillator is connected with the microprocessor to provide a clock for the work of the microprocessor; and the output terminal of the microprocessor is connected with the display screen to display the measured temperature value. Compared to the prior art, the electrothermometer is advantageous in that the cost and structure design difficulty are reduced, carrying and use are more convenient, the immersion problem caused by gaps of a window, a switch and other structures of a common electrothermometer is prevented, and a good waterproof effect is provided.

Description

A kind of without switch electronic clinical thermometer

Technical field

This utility model relates to a kind of electronic clinical thermometer, particularly a kind of without switch electronic clinical thermometer, belongs to medical measurement device technical field.

Background technology

Because mercury clinical thermometer temperature measurement accuracy is low, also can cause the highly polluted of environment, at present, the clinical thermometer that people use is mainly also electronic clinical thermometer.The electronic clinical thermometer buying on market is at present typically provided with key switch, to realize electronic clinical thermometer operation or to finish, but, the electronic clinical thermometer waterproof effect that is provided with switch is poor, cost is high, particularly, when some user's hands is dumb or inconvenient, adopts and have the electronic clinical thermometer of key switch very painstaking.As shown in Figure 1, existing electronic thermometer structure mainly contains: at table body 1 head, be provided with temperature sensor 2, table body 1 afterbody is furnished with bonnet 3, and table body 1 surface is provided with display screen 4 and key switch 5, in table body 1 inside, is provided with circuit board.At present, on market, yet there are no a kind of without switch electronic clinical thermometer.

Summary of the invention

This utility model has overcome above-mentioned the deficiencies in the prior art, provide a kind of low cost, technique simple, effective without switch electronic clinical thermometer.

The technical solution of the utility model is achieved in that

Without a switch electronic clinical thermometer, comprise table body, at table body head, be provided with temperature sensor, table body afterbody is furnished with bonnet, and table body surface is provided with display screen, in table body inside, is provided with microprocessor, RC agitator and power supply; Temperature sensor is connected with the input of microprocessor, the temperature value of the thermal source detecting is passed to microprocessor and process to judge whether to trigger temperature survey operation; Power supply is connected with microprocessor, with thinking microprocessor and each electricity consumption assembly power supply; RC agitator is connected with microprocessor, with thinking that microprocessor work provides clock; The outfan of microprocessor connects display screen, in order to displays temperature measured value.

For convenient prompting gauger measures end, as preferably, in table body, be also provided with buzzer, buzzer is connected with microprocessor, in order to accept the signal of microprocessor and to carry out auditory tone cues.

Adopted principle of the present utility model and the beneficial effect of technique scheme to be:

Compared with prior art, this utility model provide a kind of low cost, technique simple, effective without switch electronic clinical thermometer, can utilize the temperature contrast between human body and ambient temperature, when temperature sensor records the temperature fluctuation being produced by said temperature difference, trigger the temperature survey operation without switch electronic clinical thermometer.Complete in temperature survey, show after, automatic shutdown, user without any operation, only need be placed on measuring point by clinical thermometer in whole temperature survey process.

This utility model, without built-in key press detecting circuit, without button design, has reduced the cost of electronic clinical thermometer in structure, and the difficulty in structural design, convenient when carrying and using.

Because product itself is without switch, during product structure design, can reduce the gap problem that table cover itself is introduced due to button, reduced the gap that the structure such as electronic clinical thermometer form, switch of general type need to exist and the immersion problem producing can simply be accomplished good waterproof effect during structural design.

The specific embodiment

The specific embodiment of the present utility model is as follows:

Embodiment: a kind of without switch electronic clinical thermometer, as shown in Fig. 2～3, comprising:

Table body 1, is provided with temperature sensor 2 at table body 1 head, and table body 1 afterbody is furnished with bonnet 3, and table body 1 surface is provided with display screen 4, in table body 1 inside, is provided with microprocessor, RC agitator and power supply; Temperature sensor 2 is connected with the input of microprocessor, the temperature of temperature sensor 2 human body also reaches microprocessor and ambient temperature is carried out diversity ratio pair, when existence produces large temperature fluctuation by said temperature difference, trigger the temperature survey operation without switch electronic clinical thermometer; Power supply is connected with microprocessor, with thinking microprocessor power supply; RC agitator is connected with microprocessor, with thinking that microprocessor work provides clock; Buzzer is connected with microprocessor, and in order to accept the signal of microprocessor and to carry out auditory tone cues, when thermometric finishes, buzzer is made prompting sound and finished with prompting user thermometric; The outfan of microprocessor connects display screen 4, and the thermometric value that temperature sensor is collected shows, informs user in display screen 4.

As shown in Figure 4, in use, without switch clinical thermometer, utilize the temperature contrast between human body and environment, human body is detected, when temperature sensor 2 record temperature contrast and produce large temperature fluctuation time, such as temperature rise in 4 seconds is greater than 2 ℃, trigger the temperature survey operation without switch electronic clinical thermometer.When thermometric process finishes, will send buzzing prompt tone and finish to represent thermometric, on display screen 4, show thermometric value simultaneously, in the certain hour after thermometric process finishes (as 15 seconds), without switch electronic clinical thermometer by automatic shutdown, to reach energy-conservation object.User without any operation, only need be placed on measuring point by clinical thermometer in whole temperature survey process, will automatically complete temperature survey operate without switch electronic clinical thermometer, conveniently carries out human body temperature measurement.
