Description

Children's hygrothermograph

Technical Field

The utility model relates to a hygrothermograph field, in particular to children's hygrothermograph.

Background

The hygrothermograph is a general name of thermometric instruments and hygrothermographic instruments, and can accurately judge and measure temperature and humidity. Various hygrothermographs have been designed and manufactured according to the purpose of use.

The temperature measurement design is based on the following principle that the phenomenon of expansion with heat and contraction with cold of solid, liquid and gas under the influence of temperature is utilized; under the constant volume condition, the pressure of gas (or steam) changes due to different temperatures; the action of the thermoelectric effect; the resistance changes with temperature; the influence of thermal radiation, etc. Generally, any physical property of any substance, so long as it changes monotonically and significantly with changes in temperature, can be used to mark temperature to make a thermometer, and common thermometers are rotary thermometers, semiconductor thermometers, thermocouple thermometers, optical pyrometers, liquid crystal thermometers, digital thermometers, mercury thermometers, and the like. With the continuous development of the technology, in the aspect of household thermometers, old mercury thermometers (glass tubes are fragile and mercury is toxic) are abandoned due to safety considerations, and novel electronic digital display thermometers, infrared thermometers and the like (working at low voltage, and the appearance of engineering plastics or silica gel enables the thermometers to be safer, more sensitive and more accurate) are developed.

The design of humidity measurement is based on the fact that humidity is defined as "the amount of the object image state" and that humidity referred to in daily life is relative humidity expressed as RH%. In summary, that is, the percentage of the amount of water vapor (water vapor pressure) contained in a gas (usually air) to the amount of saturated water vapor (saturated water vapor pressure) in the same air, a common humidity measurement method is as follows: dynamic methods (double pressure method, double temperature method, split flow method), static methods (saturated salt method, sulfuric acid method), dew point method, dry and wet ball method and electronic sensor method.

It has been found that the optimum indoor temperature is preferably maintained at about 18 deg.C, the relative humidity is preferably maintained at about 30-40%, and the optimum indoor temperature is preferably maintained at about 25 deg.C, the relative humidity is preferably maintained at about 40-50%. In the family with babies, the indoor temperature is preferably about 20 ℃ and the humidity is preferably kept between 50 and 60 percent under the general condition. Can be properly adjusted according to the characteristics of aversion to cold and heat of children. However, in order to replace the battery, the conventional thermo-hygrometer usually adopts a detachable battery cover, and for children, the battery cover is easily loosened due to vibration or misoperation of children, so that small parts such as the battery cover or the battery are in danger of being eaten by mistake.
