Abstract
The invention discloses combined equipment for researching an ice melting point, a water boiling point and the specific heat capacity of liquid. The combined equipment comprises an iron stand, an alcohol lamp (8) and an asbestosed wire gauze, wherein the alcohol lamp (8) is arranged on an iron stand base (9). The combined equipment is characterized in that the upper end of the iron stand is movably connected with a connecting rod, wherein an iron block (4) is welded on the connecting rod; a digital temperature meter display screen (1) is arranged on the iron block (4); a 9V motor power supply (2) and a switch are arranged behind the digital temperature meter display screen (1); the digital temperature meter display screen (1) is connected with a temperature meter probe (6); the 9V motor power supply (2) is connected with a stirring connecting rod (5) below the iron block (4); a stirring impeller (7) is arranged at the bottom end of the stirring connecting rod (5). According to the combined equipment, three experiments can be made more simply and intelligently, time is greatly saved for the experiments, and the classroom efficiency is improved.
Description
Technical field
The invention belongs to experiment device for teaching, relate to one particularly and probe into ice fusing point, water boiling point, specific heat of liquid unit equipment.
Background technology
In the middle of the process of learning physics, have various experiments, various glass apparatus can be used, the breakables such as such as beaker, glass bar, test tube, thermometer.In three experimental provisions probing into ice fusing point, water boiling point, specific heat of liquid, just there is glass apparatus, not carefully just easily smash these glass apparatus, hurt the finger of student.In addition, when doing these experiments, also find too to bother in the process of assembling experiment equipment, thermometer fine rule hangs, and heating process also will constantly stir, very difficultly.3rd, these three experiments all need thermometer, and each reading, and in order to reduce error, sight line must be equal with liquid level, time-consumingly difficultly do not say, reading error is also larger.
Summary of the invention
The object of the invention is in order to overcome traditional experiment device exist equipment many, assemble the drawbacks such as time-consuming, reading is difficult, stirring is difficult, and provide one to probe into ice fusing point, water boiling point, specific heat of liquid unit equipment, it is all simpler, intelligent that this combination unit makes three kinds of experiments do, for experiment saves a lot of time, improve classroom efficiency.
Object of the present invention and to solve its technical problem underlying be come by the following technical solutions
Realize: one probes into ice fusing point, water boiling point, specific heat of liquid unit equipment, comprise iron stand, spirit lamp and asbestos gauge, iron stand base puts spirit lamp, iron stand movable upper end connects connecting rod, connecting rod welds iron block, iron block is installed digital thermometer display screen, 9V motor power and switch is had after digital thermometer display screen, digital thermometer display screen is connected with thermometer probe, and 9V motor power is connected with the stirring connecting rod under iron block, and stirring connecting rod bottom has paddle wheel.
Described digital thermometer display screen has shell.
Described paddle wheel is plastics flabellum.
The present invention compared with prior art has obvious advantage and beneficial effect.From above technical scheme, the present invention has following characteristics:
(1) student experimenting process, digital temperature meter instead of original thermometer, convenient reading, for experiment saves a lot of time, improves classroom efficiency.
(2) this device uses propeller agitation, thus eliminates the process that we stir with hand-held thermometer, whole experiment is done simpler, intelligent.
(3) this device is arranged on iron stand, can freely be elevated, and adjustment height, is adapted at testing in the glass container of various shape.
(4) thermometer and propeller agitation are integrated by this experimental provision, modular device is more succinct than original experimental provision, more humane, and this device also can do the experiment of " fusing point probing into ice ", " probing into the boiling of water " and " probing into specific heat of liquid ", can Reusability, widespread use, has promotional value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention,
Fig. 2 is prior art schematic diagram.
Mark in figure: 1, digital thermometer display screen, 2,9V motor power, 3, shell, 4, iron block, 5, stir connecting rod, 6, thermometer probe, 7, paddle wheel, 8, spirit lamp, 9, iron stand base.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, ice fusing point, water boiling point, specific heat of liquid unit equipment embodiment, feature and effect thereof are probed into the one proposed according to the present invention, is described in detail as follows.
See Fig. 1, one probes into ice fusing point, water boiling point, specific heat of liquid unit equipment, comprise iron stand, spirit lamp 8 and asbestos gauge, iron stand base 9 is put spirit lamp 8, iron stand movable upper end connects connecting rod, connecting rod welds iron block 4, iron block 4 is installed digital thermometer display screen 1,9V motor power 2 and switch is had after digital thermometer display screen 1, digital thermometer display screen 1 is connected with thermometer probe 6,9V motor power 2 is connected with the stirring connecting rod 5 under iron block 4, and stirring connecting rod 5 bottom has paddle wheel 7.
Described digital thermometer display screen 1 has shell 3.
Described paddle wheel 7 is plastics flabellum.
Innovation of the present invention is:
First, thermometer is improved, use new digital thermometer.
Secondly, increase a stirrer, can even automatic stirring, prevent the generation of hot accident.
Again, increase a connecting rod in the behind of this device, can freely adjustment height, be applicable to different containers.
Finally, this device is combined into one, convenient installation, operation.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, anyly do not depart from technical solution of the present invention content, the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
