Abstract
The utility model relates to an atmospheric element demonstrating experiment instrument. The atmospheric element demonstrating experiment instrument can be used for visually and quickly carrying out the demonstrating experiment for atmospheric elements (air temperature, air pressure and humidity). In the utility model, a sealed main air chamber is formed by a transparent and tubular glass container, an upper cover and a base. The upper part of the main air chamber is provided with a measuring instrument, and a ventilating device, an air discharging device, a heating and drying device and a humidifying device are arranged in the base. The devices are operated so that the air temperature, the humidity and the air pressure in the main air chamber are changed, and then the numerical values can be read out from the measuring instrument. The utility model can change the meteorological elements during short time so that students can rapidly comprehend the concepts of the meteorological elements and can visually observe the meteorological elements. The utility model is an essential demonstrating experiment instrument for teaching in colleges, universities and high schools.
Description
The utility model is that atmosphere elements (temperature, humidity, air pressure) is measured the lecture experiment instrument.
Atmospheric air temperature, air pressure, humidity are main meteorological elements, also be meteorological observation must survey project, thereby be the important content of courses of geographical subject.Relevant notion and surveying instrument, measuring method all must be item by item by classroom instructions, and in outdoor observation field practice, the student are familiar with to some extent to notion, can grasp understanding to relevant instrument and measuring method thereof.But, these meteorological elements, the general time changes not obvious, need be through just observing its variation for a long time.Be difficult to especially observe to comparing opposite extreme situations, also be difficult to repetition.Particularly, be difficult to visual understanding and understanding especially to the air humidity notion.For middle school student, owing to be subjected to all condition restriction, to understanding related content difficulty especially.
The purpose of this utility model is: a kind of lecture experiment instrument is provided, as atmosphere relevant speciality teaching demonstration teaching aid, or as the laboratory experiment device, also can be used as middle school student's geography or physics teaching demonstration teaching aid.By this device, in a little space, temperature, humidity, air pressure or its combination are changed, then measure the situation of change of temperature, humidity, air pressure in this little space, reach the purpose of demonstration teaching by temperature, humidity, the barometric surveying instrument that is arranged on this space.
For achieving the above object, design of the present utility model is: a clear glass cylindrical container, loam cake and base are sealed to a main gas tank, main gas tank is provided with measurement instrument in the top, and blower fan, heat drier, electric hot plate are set in the base, and main gas tank has the air channel to communicate with base.One baffle is arranged between air channel and the main gas tank, between the wall of baffle and main gas tank the space is arranged.Measurement instrument can be do, wet bulb thermometer, aneroid pressure meter, the standard hair hygrometer, numeral shows electronic measuring instrument.By operation blower fan, heat drier, electric hot plate, the meteorological element in the main gas tank is changed, read variation numerical value by measurement instrument.Can make air drying or make air vaporization humidification, even make air near saturated, the designation data that reads psychrometer obtains temperature, humidity changes value; Also can the air pressure in the main gas tank be changed, read barometer numerical value, obtain the value of air pressure change.
The utility model compared with prior art has the following advantages:
1. the variation of the air key element in the main gas tank is random, to relatively the opposite extreme situations demonstration is obvious;
2. help notion and measuring method that the student learnt, understands, was familiar with atmospheric air temperature, humidity, air pressure at short notice;
3. have intuitive, versatility;
4. consider the situation of the actual conditions of school, particularly general high school, fully simplify during this instruments design that most of spare part in common use that adopts makes its cost low, simple in structure, reliable.
5. this instrument also can be used as the teaching demonstration instrument of molecular thermalmotion in the physics.
Accompanying drawing is a right section synoptic diagram of the present utility model, and the utility model is made of following components:
1, main gas tank 2, baffle 3, base
4, air channel 5, heat drier 6, blower fan
7, fan house 8, vaporizer 9, electric hot plate
10, water inlet dropper 11, operating switch 12, loam cake
13, instrument supporting plate 14, instrument 15, wind output channel
16, gim peg 17, sensing ball 18, clear glass cylindrical container
Embodiment one, and is universal
The contrast accompanying drawing, this instrument is made up of main gas tank 1, base 3, loam cake 12.Main gas tank 1 is a clear glass cylindrical container 18, and tube bottom, garden is mounted with base 3, and loam cake 12 is stamped on top, and totally four of gim pegs 16 make loam cake 12, main gas tank 1, base 3 is fixedly connected becomes integral body.
The operating switch 11 that is placed on the base 3 is one group of tape light switch, has total power switch, blower fan just changeing reversal switch, air heat exsiccator switch, electrothermal plate switch.Other has the into inlet of water dropper 10, so that add water.
Certainly, outward appearance of the present utility model, base form and material can not be restricted to one pattern, and the volume size also can change to some extent according to cost, and each operating switch position of sound production form also can change to some extent, and barometer also can be placed in instrument supporting plate front.
Embodiment two, plain edition
Structure, outward appearance, form such as embodiment one just cancel wet bulb thermometer, and the standard hair hygrometer is placed in the main gas tank 1, directly measure the relative humidity of air in the main gas tank 1, make observation more directly perceived, so that use in the middle school.
Embodiment three, high type
Structure, outward appearance, form such as embodiment one only are to use numeral to show electronic thermometer, hygrometer, barometer (promptly numeral shows electronic measuring instrument).Sensor is separately placed in the main gas tank 1, replace to do, wet bulb thermometer and aneroid pressure meter, make measurement more accurate, more directly perceived, become laboratory in colleges and universities's experimental apparatus.
According to design of the present utility model, can also constitute other similar device, give unnecessary details no longer one by one.
