Description
Technical field
The utility model relates to a kind of chemical experiment device, especially a kind of smog Tyndall phenomenon simulation demonstrating apparatus.
Background technology
Chemistry is a natural science based on experiment, and wherein Tyndall phenomenon observation experiment is a lecture experiment very important in chemistry teaching initial stage.At present, the device of Tyndall phenomenon lecture experiment comprises a cubical box, wherein be shaped with light source and silica dish, when testing, first box is opened, in silica dish, difference pouring soln, colloid and turbid liquid, opens light source afterwards, according to different experimental results demonstration Tyndall phenomenon.
But in actual experiment process, because this body structure of experimental provision is less, experimental result is subject to environmental limit in addition.Its result is also not obvious, and student often cannot observe the phenomenon of experiment, is difficult to reach object student being understood to experimental principle and relevant knowledge.And existing apparatus for demonstrating can only be demonstrated the Tyndall phenomenon of liquid, can not demonstrate aerocolloidal Tyndall phenomenon.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one kind of multiple demo functions, and experimental result is obvious, intuitively three-dimensional, a kind of smog Tyndall phenomenon simulation demonstrating apparatus can demonstrated gasoloid.
The utility model is achieved through the following technical solutions:
A kind of smog Tyndall phenomenon simulation demonstrating apparatus, it is characterized in that: comprise upper cartridge body and lower box body, this upper cartridge body is inlaid in the upper end of lower box body, described upper cartridge body and lower box body all adopt transparent material, the cavity placing smokeable substance is shaped with in this lower box body, the interval that described lower box body sidewall inner edge is parallel to each other is provided with two planar optics, the reflective surface of described two planar optics is mounted opposite, wherein the top of a planar optics is shaped with a direct projection light source projected to another plate plane minute surface, inner edge, lower box body upper end above this direct projection light source is shaped with a through hole, in this through hole, contraposition is embedded with described upper cartridge body, a scattering light source be connected with power supply is shaped with in this upper cartridge body, this scattering light source is to the bottom projection in upper cartridge body, the inner edge, bottom of described upper cartridge body is embedded with the dividing plate that is shaped with multiple exhaust hole, described upper cartridge body is connected with the cavity in lower box body by exhaust hole.
And described lower box body bottom surface central authorities are embedded with a heat-conducting plate, be shaped with multiple exhaust smoke hole be in communication with the outside in described lower box body sidewall upper portion, described lower box body sidewall outer rim is provided with one for controlling the control panel of direct projection light source.
And described upper cartridge body sidewall outer rim is provided with the power supply of a control scattering light source.
Advantage of the present utility model and good effect are:
In the utility model, when cavity is built-in with the smokeable substance of burning, the air hole that smog can be made by dividing plate enters upper cartridge body, because upper cartridge body and lower box body all adopt transparent material, therefore the Tyndall phenomenon coordinating smog to produce direct projection light source and scattering light source respectively carries out classification demonstration, and then the three-dimensional Tyndall phenomenon observed in gasoloid directly perceived; The heat-conducting plate made in lower box body bottom surface can be used for the smokeable substance of placement to ignite, thus carries out experimental demonstration, and smokeable substance of avoiding igniting outside cavity causes the pollution of experimental situation; Excessive smog can be discharged in cavity by the exhaust smoke hole that lower box body upper end is made, thus avoids the observation affecting experimental result.

Fig. 1 is structural representation of the present utility model;
Structural representation when Fig. 2 is the utility model use.
Embodiment
Elaborate to the utility model below by embodiment, described embodiment is illustrative, and nonrestrictive, can not limit protection domain of the present utility model with this.
A kind of smog Tyndall phenomenon simulation demonstrating apparatus, innovation of the present utility model is, comprise upper cartridge body 3 and lower box body 7, this upper cartridge body is inlaid in the upper end of lower box body, described upper cartridge body and lower box body all adopt transparent material, the cavity 9 placing smokeable substance 11 is shaped with in this lower box body, the interval that described lower box body sidewall inner edge is parallel to each other is provided with two planar optics 8, the reflective surface of described two planar optics is mounted opposite, wherein the top of a planar optics is shaped with a direct projection light source 14 projected to another plate plane minute surface, inner edge, lower box body upper end above this direct projection light source is shaped with a through hole 13, in this through hole, contraposition is embedded with described upper cartridge body, a scattering light source 2 be connected with power supply 1 is shaped with in this upper cartridge body, this scattering light source is to the bottom projection in upper cartridge body, the inner edge, bottom of described upper cartridge body is embedded with the dividing plate 5 that is shaped with multiple exhaust hole 4, described upper cartridge body is connected with the cavity in lower box body by exhaust hole.
In the present embodiment, the carrying out of conveniently testing, described lower box body bottom surface central authorities are embedded with a heat-conducting plate 10, are shaped with multiple exhaust smoke hole 6 be in communication with the outside in described lower box body sidewall upper portion, and described lower box body sidewall outer rim is provided with one for controlling the control panel 12 of direct projection light source.
In the present embodiment, in order to control respectively experiment, described upper cartridge body sidewall outer rim is provided with the power supply of a control scattering light source.
Use procedure of the present utility model is:
When the utility model uses, first upper cartridge body is separated placement with lower box body by experimenter, afterwards smokeable substance is positioned in cavity, the through hole upper end of afterwards upper cartridge body setting-in and lower box body being made, afterwards experimental provision is positioned over above iron stand 15, and add thermal ignition smokeable substance by spirit lamp 16, the a large amount of smog produced after smokeable substance burning enter in upper cartridge body by exhaust hole, experimenter can experimentally demand open the transparency material that direct projection light source and scattering light source coordinate upper cartridge body and lower box body to adopt respectively and demonstrates aerocolloidal Tyndall phenomenon afterwards, but when in experiment, smog is too much, the exhaust smoke hole that smog can be made along lower box body is discharged, thus avoid the impact on experimental observation.
In the utility model, when cavity is built-in with the smokeable substance of burning, the air hole that smog can be made by dividing plate enters upper cartridge body, because upper cartridge body and lower box body all adopt transparent material, therefore the Tyndall phenomenon coordinating smog to produce direct projection light source and scattering light source respectively carries out classification demonstration, and then the three-dimensional Tyndall phenomenon observed in gasoloid directly perceived; The heat-conducting plate made in lower box body bottom surface can be used for the smokeable substance of placement to ignite, thus carries out experimental demonstration, and smokeable substance of avoiding igniting outside cavity causes the pollution of experimental situation; Excessive smog can be discharged in cavity by the exhaust smoke hole that lower box body upper end is made, thus avoids the observation affecting experimental result.
