The cover equipped container comprises a cover and a container body, wherein the cover and the container body of the cover equipped container are connected via a rope. The ignition device is an electronic igniter, wherein a discharge ignition end of the electronic igniter extends into the cover equipped container. The demonstration device for conversion from internal energy to mechanical energy disclosed in the utility model has the advantages of simple structure, convenient preparation, easy material drawing, and obvious experimental effects.
Description
Technical field
The utility model relates to a kind of education experiment apparatus, is specifically related to a kind of interior apparatus for demonstrating that can be converted into the mechanical energy experiment.
Background technology
The interior content that can be converted into mechanical energy is more abstract knowledge point, junior physics the inside, usually can describe by concrete experiment in order to make the student can better understand this knowledge point.The experiment that can be converted into mechanical energy in present stage is used for illustrating is: heating is enclosed in invisible spectro water, adds thermogenetic water vapor the cork of closed test tube is gone out.But, heat time-consumingly, the student is in a single day absent-minded just to can't see the whole process that cork is gone out, and does not reach the purpose of experiment; And the speed that cork is gone out is very fast, gets to easily people or thing, makes experiment have certain potential safety hazard.
The utility model content
Consider the problems referred to above of prior art, according to an aspect of the present utility model, disclose and a kind ofly interiorly can be converted into the mechanical energy apparatus for demonstrating, it is characterized in that, comprise lidded container and portfire, described lidded container comprises lid and container body, and lid and the container body of described lidded container link together by rope, described portfire is ignition, and the point of discharge fire end of described ignition stretches in the lidded container.
As preferably, the point of discharge fire end of described ignition stretches in the lidded container by wire, and the container body sidewall of described lidded container is provided with wire and stretches into the hole that the lidded container end matches.
As preferably, described wire has two, and described two wires are respectively the first wire and the second wire; Described hole has two, and described two Kong Weiyu the first wires stretch into the first hole that the lidded container end matches and stretch into the second hole that the lidded container end matches with the second wire.
As preferably, described the first hole and the second hole are arranged on the container body sidewall on 1/4 height of container body bottom, and described the first hole and the second hole be 0.5cm apart.
As preferably, the diameter in described the first hole and the second hole is 1mm.
As preferably, the length of described the first wire and the second wire all is 50cm.
As preferably, the length of described rope is 2m.
As preferably, described rope is cotton thread.
As preferably, described ignition is piezoelectric ceramic ignitor.
The purpose of this utility model aims to provide more significantly experimental demonstration device of a kind of use safety, experiment effect.Compared with prior art, one of the beneficial effects of the utility model are: the utility model links together by lid and the container body of rope with lidded container, so that the Gai Buhui of lidded container disorderly flies and conveniently give for change outbound lid in the experimentation; In the utility model portfire is connected in the lidded container with two long wires, makes whole experimentation, particularly safer during starter gear.
Description of drawings
Fig. 1 shows the interior structural representation that can be converted into the mechanical energy apparatus for demonstrating according to an embodiment of the utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified, but embodiment of the present utility model is not limited to this.
Fig. 1 shows the interior structural representation that can be converted into the mechanical energy apparatus for demonstrating according to an embodiment of the utility model.As shown in Figure 1 interior can be converted into the mechanical energy apparatus for demonstrating, comprise lidded container and portfire 104, lidded container comprises covers 102 and container body 101, lid 102 links together by rope 103 with container body 101, and the point of discharge fire end of portfire 104 stretches in the lidded container by the first wire 105 and the second wire 106; Container body 101 sidewalls are provided with the first wire 105 and stretch into the first hole that the lidded container end matches and stretch into the second hole that the lidded container end matches with the second wire 106, the first hole and the second hole are arranged on container body 101 sidewalls on 1/4 height of container body bottom, the first hole and the second hole are at a distance of 0.5cm, and the diameter in the first hole and the second hole is 1mm; The length of the first wire 105 and the second wire 106 all is 50cm; Rope 103 is cotton thread, and length is 2m; Portfire 104 is piezoelectric ceramic ignitor.
When making this device, lidded container can be selected the about 250 milliliters plastic cup of common on the market capacity, the lighter that portfire can select fuel to use up; The first wire and the second wire are stretched into an end sharpening of lidded container, make its point point relatively, make its point point at a distance of 1mm, make the tip of the first wire and the second wire have Mars to skip by lighter after installing; When lidded container is holed, note not affecting the sealing of lidded container.
During experiment, in lidded container, splash into 7 to 8 alcohol, cover the lid of lidded container, make the alcohol volatilization in the lidded container be full of lidded container inside for gas, then pressing lighter makes the tip of the first wire and the second wire have Mars to skip, thereby light the gas in the lidded container, and produce blast, blast is blown up the cover of lidded container.Being converted into mechanical energy in the explanation of this phenomenon, thereby can be converted into the lecture experiment purpose of mechanical energy in the realization.
Device of the present utility model, simple in structure, easy to make, draw materials easily, experiment effect is obvious; Link together with lid and the container body of cotton thread with lidded container, make the Gai Buhui of lidded container in the experimentation disorderly fly and conveniently give for change outbound lid; Portfire is connected in the lidded container with two long wires, makes whole experimentation, particularly safer during starter gear.
