Background

Mercury thermometers, one type of expansion thermometer, have a mercury freezing point of-39 deg.C, a boiling point of 356.7 deg.C, and a measuring temperature range of-39 deg.C to 357 deg.C. The thermometer is used for measuring the temperature, is simple and visual, and can avoid the error of an external remote thermometer.

The liquid thermometer realizes the reaction to the temperature by the expansion of the liquid when heated; because mercury thermometer figures and scales are small, many people cannot understand the mercury thermometer figures or the mercury thermometer figures are more difficult to read by the old with poor eyesight.

The mercury thermometer generally needs to have a vertical line of sight with the thermometer in the reading process, and the reading is easy to generate larger errors when some users do not know the method; and some patients do not know the normal temperature range of the human body and the defined temperature range of fever and low fever.

For example, the technology disclosed in the patent CN 103557952B is improved on the basis of a mercury thermometer, so that the thermometer can realize real-time temperature feedback, but the thermometer has a complex structure, has a large amount of temperature data, needs to be matched with a computing device, and is not convenient to carry. When the temperature measuring instrument is used for measuring the temperature of a human body, the measurement is very inconvenient, and excessive waste data exists; the actual working principle of the temperature monitoring device has more similarity to the temperature monitoring of a conventional temperature sensor, and only the reliability and the accuracy of data are improved.

Simultaneously, the thermometer that the hospital used, when the temperature was surveyed to dark or night, can't see the temperature dial gauge clearly, need watch under with the flashlight or taking the bulb, had the inconvenient drawback of use.

Detailed Description

The invention is further illustrated with reference to the accompanying drawings:

as in fig. 1, a thermometer comprises an expansion element 10, said expansion element 10 comprising a capillary tube 11 and a liquid bubble 12 communicating with each other; mercury 20 is provided in the expansion element 10;

the expansion element 10, the power supply 30 and the feedback module 40 are sequentially connected in series, and current flows from the three components;

the feedback module 40 comprises a resistance module 41 and a feedback element 42 connected in series with each other; one end of the resistance module 41 far away from the feedback element 42 is connected to the capillary 11;

the resistance module 41 comprises a plurality of resistors 411 connected in parallel;

the feedback module 40 feeds back different information according to the magnitude of the current passing through it.

The end of the resistor 411 remote from the feedback element 42 is connected to an electrical connection 110 of the capillary 11, the electrical connection 110 being located within the capillary 11, the mercury being able to contact the electrical connection 110 as the mercury 20 moves within the capillary 11.

The electric connection columns 110 correspond to the positions of part of the scale marks of the capillary tube 11, the number of the electric connection columns 110 is set according to requirements, generally at 36 ℃ and 37 ℃, and when the upper end face of the mercury 20 is positioned between the two scales, the feedback element 42 feeds back information to indicate that the body temperature is normal to a user.

The electrical connection post 110 is correspondingly arranged on the capillary 11 at the positions of the graduation lines at 36 ℃, 37 ℃, 38 ℃ and 39 ℃.

The end of the power supply 30 away from the feedback module 40 is connected to the liquid bubble 12 and can be electrically conducted with the mercury 20 in the liquid bubble 12, and when the mercury 20 contacts the connecting column 110, the mercury 20 can also become an electric conductor, so that the whole circuit forms a current loop.

The feedback module 40 is provided with an indicating element 60 in parallel; the feedback module 40 and the end of the indicator element 60 remote from the power supply are connected to a capillary tube.

The connection of the indicator element 60 to the capillary tube 11 is closer to the liquid bubble 12 than the connection of the feedback module 40 to the capillary tube 11.

A plurality of the resistors 411 have equal resistance values.

The feedback element 42 is a color changing light emitting diode.

When the current in the color-changing light-emitting diode changes, the color-changing light-emitting diode also emits light with different colors, and the specific technology is known.

One working mode of the invention is as follows:

as shown in fig. 1, when mercury 20 in the liquid bubble 12 expands into the capillary tube 11 after being heated, the capillary tube 11 is provided with temperature scales, the arrangement of the scale marks is the same as that of a common thermometer, and the mercury reaches the temperature which can reflect the measurement of the mercury at the corresponding scale marks;

after the mercury 20 rises in the capillary tube 11, the upper end surface of the mercury 20 rises gradually;

as shown in fig. 1, when the liquid level of the mercury 20 reaches the left terminal of the indicating element 60, a current loop is formed, and the indicating element 60 is powered on to emit an indicating signal, such as light;

due to the particularity of the mercury thermometer, after the mercury thermometer is used, a heat source is started to return to the liquid bubble 12, the mercury 20 needs to be thrown back into the liquid bubble 12, when the liquid level on the mercury 20 descends to the lower end of the left terminal of the indicating element 60, the current of the indicating element 60 is short-circuited, and information display is stopped; this function can also be used to observe whether the thermometer mercury 20 has returned or not at the time of second use, avoiding problems with the measurement result.

When the mercury 20 reaches the 36 c position, resistor R4 is also switched into the circuit, causing a current I in the feedback element 42₁Introducing; r continues to rise to 37 ℃ with 20 mercury columns₃Parallel access R₄The two-terminal circuit allows a current I2 to pass through the feedback element 42; r rises with mercury 20_nParallel access R₄Two terminal circuits in the feedback element 42With current I_nIntroducing;

in connection with the circuit diagram of figure 2,as the resistors R connected in parallel are more and more, R is accordingly_{And are}Gradually decreases.

One setting is R₁＝R₂＝R_nIn order to adapt to the current values of the light emitting diode at different light emitting stages, the settings of a plurality of resistance values can be adjusted according to needs, so that the feedback element 42 can display different information through the current of the feedback element 42 after different resistors are connected into the circuit;

since the indicator 60 and the feedback module 40 are connected in parallel across the electrical connection, both voltages are the same and constant; as R and decreases, I_{Feedback module}Gradually increasing, the current through the feedback element 42 also gradually increasing; the feedback element 42 can display different information when the current is applied;

as an example, when the current is 1A, the feedback element 42 emits yellow light, when the current is 2A, the feedback element 42 emits green light, and when the current is 3A, the feedback element 42 emits red light;

in conjunction with fig. 1, one way of further defining the matching is: when mercury 20 touches R₅When the post 110 is electrically connected (35℃.), the current passing through the feedback module 40 causes the feedback element 42 to emit yellow light, indicating low heat; when the mercury 20 touches the R4 electrical connection post 110 (36 ℃), the current passing in the feedback module 40 causes the feedback element 42 to emit green light, indicating normal; when the mercury 20 touches the R3 electrical connection post 110 (37 ℃), the current passing in the feedback module 40 causes the feedback element 42 to glow red, indicating heating; when the mercury 20 touches the R1 electrical connection post 110 (39 ℃), the current passing in the feedback module 40 causes the feedback element 42 to glow purple, indicating high heat.

It will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the general spirit and concept of the invention. All falling within the scope of protection of the present invention. The protection scheme of the invention is subject to the appended claims.
