technical field

Background technique

Before the invention of electronic thermometers, mercury thermometers were widely used to measure the body temperature of the human body. People used the principle that mercury naturally expands when it is heated and shrinks when it is cold to make mercury thermometers. Generally, mercury thermometers are made of glass. The mercury column and the mercury ball at the end have different shapes and sizes depending on the measurement position. For example, the oral temperature measurement is slender, and the anal temperature measurement is short and round or distinguished by color. During the temperature measurement process, the thermometer Mercury expands when heated, so that the expanded mercury rises along the mercury column, and the user can read the volume and set the data according to the external scale; however, the mercury thermometer is fragile, and the measured value varies with the angle of view. Thermometers contain mercury (mercury) metal. Because mercury metal and its compounds seriously harm humans, environmental ecology, animals and plants, it has become a trend for countries all over the world to ban mercury. Therefore, the promotion of electronic thermometers is imperative.

The measurement principle of the general electronic thermometer is to use the built-in timing circuit of the integrated circuit to calculate the time required for the oscillating circuit formed by the externally connected reference resistance and capacitance to oscillate to a specific number of times as the reference time, and then switch to the temperature-sensitive resistor and the above-mentioned oscillation. The same capacitor in the circuit oscillates, and obtains the number of oscillations within the reference time, which is converted into a data signal and sent to the display through the internal calculation of the microprocessor; due to the great progress in science and technology, people's requirements for sanitary conditions are also increasing. Since the users of household electronic thermometers are all their relatives, ordinary users may have no doubts about sharing household electronic thermometers, but the electronic thermometers used in medical institutions are shared by all patients. Simple disinfection such as alcohol cannot remove people's doubts about virus infection.

Therefore, in view of the problems existing in the above-mentioned existing structure, how to develop a more ideal and practical innovative structure, which is eagerly awaited by consumers, is also the goal and direction that relevant companies must work hard to develop breakthroughs.
