The apparatus comprises a pedestal, a first non-return valve, a second non-return valve, a gas-guide tube, a beaker, an electric motor and an oval cam, wherein the pedestal is provided with an elastic air bag and an alcohol lamp, and an air outlet opening of the elastic air bag is connected with the first non-return valve; an air inlet opening of the elastic air bag is connected with the beaker orderly through the second non-return valve and the gas-guide tube; the beaker is arranged above the alcohol lamp; the top part of the beaker is provided with a beaker cap which is provided with at least a round hole, a cambered surface of the oval cam acts on the upper surface of the elastic air bag, and the oval cam is driven to rotate by the electric motor. Smoking processes can be simulated through the smoking harm demonstration apparatus, coke tar left in human bodies after smoking can be refined and displayed to students, and the students can be effectively improved in understanding of smoking harm.
Description
Technical field
The utility model relates to a kind of harmfulness of smoking apparatus for demonstrating, belongs to junior middle school's Political Teaching apparatus.
Background technology
In junior middle school's politics lesson, teacher need to educate student and resist bad temptation at one's side, in these bad temptation, just comprises smoking.Smoking can make the interior residual a kind of tar of people's body, and this tar contains more than 30 kind of carcinogen, and health in serious threat.On classroom, owing to lacking demonstration teaching aid intuitively, teacher can only instruct student by the mode of oral account, and this can not effectively improve the understanding of student to the harm of smoking.
Utility model content
The utility model, for the problem in background technology, proposes a kind of harmfulness of smoking apparatus for demonstrating.
The utility model, for overcoming the above problems, adopts following technical scheme:
A harmfulness of smoking apparatus for demonstrating, comprises base, the first retaining valve, the second retaining valve, wireway, beaker, motor and oval cam; Described base is provided with elastic bag and spirit lamp; The gas outlet of described elastic bag is connected with the first retaining valve, and the air intake opening of elastic bag is connected with beaker by the second retaining valve and wireway successively; Described beaker is located at spirit lamp top, and beaker top is provided with bowl cover, has at least one circular hole on bowl cover; The cambered surface of described oval cam acts on elastic bag upper surface; Described motor drives oval cam to rotate.
Further, described Circularhole diameter is 8-10mm.
Preferably, described motor adopts DC speed-reducing.
Technique effect:
1, the utility model can be to the process simulation of smoking, and the tar remaining in body after smoking is extract, and shows student, has effectively improved the understanding of student to the harm of smoking.
2, the utility model is rational in infrastructure, designs ingeniously, and convenient operation, is adapted at each school and promotes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the constitutional diagram of oval cam when elastic bag is pushed.
Label title in Fig. 1, Fig. 2: 1, base; 2, elastic bag; 3, the first retaining valve; 4, the second retaining valve; 5, wireway; 6, beaker; 7, motor; 8, oval cam; 9, bowl cover; 10, circular hole; 11, spirit lamp; 12, pure water; 13, cigarette; 14, electric machine support; 15, beaker support.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is done in further detail and is introduced:
Structure of the present utility model as shown in Figure 1, comprises base 1, the first retaining valve 3, the second retaining valve 4, wireway 5, beaker 6, motor 7 and oval cam 8; Described base 1 is provided with elastic bag 2 and spirit lamp 11; The gas outlet of described elastic bag 2 is connected with the first retaining valve 3, and the air intake opening of elastic bag 2 is connected with beaker by the second retaining valve 4 and wireway 5 successively; Described beaker 6 is located at spirit lamp 11 tops by beaker support 15, and beaker 6 tops are provided with bowl cover 9, has at least one circular hole 10 on bowl cover 9; The cambered surface of described oval cam 8 acts on elastic bag 2 upper surfaces; Described motor 7 drives oval cam 8 to rotate.
Described circular hole 10 diameters are 8-10mm, are slightly larger than cigarette external diameter (8mm), during experiment, cigarette directly can be inserted in circular hole 10 and are fixed.
Described motor 7 adopts DC speed-reducing, and motor 7 is fixed on base 1 by electric machine support 14, for driving oval cam 8 to rotate.
Described the first retaining valve 3 and the second retaining valve 4 all adopt cooling gas check valve.Gas in elastic bag 2 can be discharged elastic bag 2 by the first retaining valve 3; Gas in wireway 5 can enter elastic bag 2 by the second retaining valve 4.
During experiment, first in beaker 6, pour pure water 12 into, then cigarette 13 one end are penetrated to circular hole 10 and be fixed, and the other end is lighted, afterwards by motor 7 power connections, motor 7 drives oval cam 8 to rotate while rotating.When the major axis of oval cam 8 is rotated to vertical direction by horizontal direction, oval cam 8 can push elastic bag 2, and a part of gas in elastic bag 2 is extruded to (as shown in Figure 2) by the first retaining valve 3.When the major axis of oval cam 8 is rotated to horizontal direction by vertical direction, oval cam 8 no longer pushes elastic bag 2, now, because ambient pressure is greater than the air pressure in elastic bag 2, ambient atmos can pour in elastic bag 2 by cigarette 13, beaker 6, wireway 5 and the second retaining valve 4 successively, and elastic bag 2 is restored to the original state (as shown in Figure 1), when gas process beaker 6, the smoke from cigarette in gas can be caught by the pure water in beaker 6.So, when motor 7 rotates always, elastic bag 2 is exhaust and air-breathing constantly, and the gas that contains smoke from cigarette is sucked in beaker 6, and the smoke from cigarette that the pure water in beaker 6 is caught just can increase gradually.The spirit lamp 11 of beaker 6 belows can evaporate the moisture in beaker, and the tar that leaves black shows student.
