The device is simple in structure and visual in demonstration. The device comprises a box, wherein a bulb is arranged in the middle of the upper portion of the box, and a wire connected with the bulb is connected with a plug outside the box via the box; one side of the bulb is provided with a black first glass bottle, the other side of the bulb is provided with a transparent second glass bottle, the two bottles have the same volume, and distance from the first glass bottle to the bulb and the distance from the second glass bottle to the bulb are the same; and the first glass bottle and the second glass bottle are both connected with one end of a flexible pipe in the box, and the other end of the flexible pile extends out of the box and is connected with one end of a U-shaped pipe which is vertically arranged, and the other end of the U-shaped pipe is communicated with the atmosphere.

Description

A kind of device of demonstrating gas pressure intensity and temperature relation

Technical field:

The utility model is divided by International Patent Classification (IPC) (IPC) and is belonged to physical department, instrument branch, education; Cryptology; Show; Advertisement; The big class of seal, education or demonstration equipment; Be used to the apparatus of imparting knowledge to students or communicating by letter with blind person, deaf person or mute; Model; Planetarium; Terrestrial globe; Map; The figure watch group, the teaching aid technical group field of electricity operation; Classification number is G09B5/00, in particular, relates to a kind of device of demonstrating gas pressure intensity and temperature relation.

Background technology:

On the physics lesson, the student is difficult to understand when lecturing gas pressure intensity with temperature relation, does not have a kind ofly can show the object teaching apparatus that concerns between gas pressure intensity and the temperature variation, make teacher in teaching to the explanation of this knowledge also difficulty relatively, the student is difficult for understanding.

Summary of the invention:

The utility model is exactly at the problems referred to above, and a kind of simple in structure, the demonstration gas pressure intensity of demonstrating visual and the device of temperature relation are provided.

For reaching above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, and the utility model comprises casing, its structural feature: casing is provided with bulb in the middle of the top, and the electric wire that links to each other with bulb links to each other with the outer plug of casing through casing; The both sides of casing upper bulb are respectively arranged with first vial of the identical black of volume and the second transparent vial, and the distance between described first vial and the bulb and second vial equate with distance between the bulb; First vial all links to each other with an end of the flexible pipe in the casing with second vial, and the other end of flexible pipe stretches out casing, and links to each other with an end of the U-shaped pipe that vertically is provided with, and the other end of U-shaped pipe is communicated with atmosphere.

The beneficial effects of the utility model:

1, simple in structure:

Casing of the present utility model is provided with bulb in the middle of the top, and the electric wire that links to each other with bulb links to each other with the outer plug of casing through casing; The both sides of casing upper bulb are respectively arranged with first vial of the identical black of volume and the second transparent vial, and the distance between described first vial and the bulb and second vial equate with distance between the bulb; First vial all links to each other with an end of the flexible pipe in the casing with second vial, and the other end of flexible pipe stretches out casing, and links to each other with an end of the U-shaped pipe that vertically is provided with, and the other end of U-shaped pipe is communicated with atmosphere; Its member is few, and the utility model is simple in structure thus.

2, demonstrating visual:

When using the utility model, in two U-shaped pipes, inject the water of same amount earlier, link to each other with two flexible pipes vertically then; Plug with bulb inserts in the power supply again, and bulb lights; Bulb heats up first vial of bulb both sides and second vial by illumination; Because first vial is a black, it is many to absorb heat, so first vial raises soon than the second vial temperature; Gas pressure intensity in such first vial is also big than the gas pressure intensity in second vial, thereby the water in the compressing U-shaped pipe moves, and can observe the relation of temperature and pressure by the position of water intuitively, demonstrating visual.

Description of drawings:

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.Protection domain of the present utility model will not only be confined to the statement of following content.

Fig. 1 is a structural representation of the present utility model;

1 is that casing, 2 is that first vial, 3 is that flexible pipe, 4 is that U-shaped pipe, 5 is that bulb, 6 is that water, 7 is that second vial, 8 is that electric wire, 9 is a plug in the accompanying drawing.

Embodiment:

The utility model comprises casing 1, is provided with bulb 5 in the middle of casing 1 top, and the electric wire 8 that links to each other with bulb 5 links to each other with casing 1 outer plug 9 through casing 1; The both sides of casing 1 upper bulb 5 are respectively arranged with first vial 2 of the identical black of volume and the second transparent vial 7, and the distance between described first vial 2 and the bulb 5 and second vial 7 equate with distance between the bulb 5; First vial 2 all links to each other with an end of the flexible pipe 3 in the casing 1 with second vial 7, and the other end of flexible pipe 3 stretches out casing 1, and links to each other with an end of the U-shaped pipe 4 that vertically is provided with, and the other end of U-shaped pipe 4 is communicated with atmosphere.

During use, in two U-shaped pipes 4, inject the water 6 of same amount earlier, link to each other with two flexible pipes 3 vertically then; Plug 9 with bulb 5 inserts in the power supply again, and bulb 5 lights; Bulb 5 heats up first vial 2 of bulb 5 both sides and second vial 7 by illumination; Because first vial 2 is a black, it is many to absorb heat, so first vial, 2 to the second vials, 7 temperature raise soon; Gas pressure intensity in such first vial 2 is also big than the gas pressure intensity in second vial 7, thereby the water 6 in the compressing U-shaped pipe 4 moves, and can observe the relation of temperature and pressure by the position of water 6 intuitively.

Above content is to further describing that the utility model is done in conjunction with concrete preferred implementation; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the definite protection domain of claims that the utility model is submitted to.
