Abstract
The utility model discloses a gas generator, which is an instrument for chemistry experiment. The gas generator is improved by aiming at the disadvantages of a Kipp gas generator, the utility model reserves the advantages of the Kipp gas generator and as well as overcomes the disadvantages of the Kipp gas generator, and the aim of the gas generator is to provide the gas generator which is fit for scientific research and a teacher to demonstrate an experiment and also fit for students to do the experiment. The novel gas generator is mainly characterized in that the novel gas generator is composed of a pear-shaped funnel, a sphere body and a mastoid process head, and the sphere body is provided with a side opening which is connected with two plungers by a rubber plug. The utility model divides a plurality of sizes of 250 milliliters, 150 milliliters, 100 milliliters, 60 milliliters and 30 milliliters, the bigger is used for the scientific research and the teacher to demonstrate the experiment, and the smaller is used for students to do the experiment.
Description
The utility model is the New Type of Gas Generator at the shortcoming improvement of opening general gas generator, not only is suitable for scientific research and all is demonstration experiment usefulness, also is suitable for the classmate and does experiment usefulness.
Existingly open general gas generator and form by ball-type funnel and ball-type body and hemisphere etc., its advantage is to supply with stable air-flow at any time, time spent cessation reaction at any time not, its shortcoming is that volume is big, device bothers, consumption acid is many, topmost shortcoming is that it has huge hemisphere, acid in the hemisphere can not contact with solid medicine effectively again and react, so it is many to consume acid.But hemisphere again can not be too little, otherwise gas is gone into the ball-type funnel to acid fracturing, moves on the center of gravity, topples over easily.
The purpose of this utility model provides a kind of gas generator of improvement, and it had both kept the advantage that opens general gas generator, has overcome the shortcoming that opens general gas generator again.Make it become the gas generator that scientific research, teacher modeling experiment and classmate's experiment can both be used.This instrument divides 250 milliliters, 150 milliliters, 100 milliliters, 60 milliliters and 30 milliliters of five kinds of specifications, and big tests usefulness for scientific research and teacher modeling, and little tests usefulness for the classmate.
The purpose of this utility model realizes in the following manner: New Type of Gas Generator is made up of the mastoid nob of pear funnel and ball-type body and bottom, the side mouth of ball-type body connects the two-way piston, the long tube of pear funnel inserts in the mastoid nob pipe of ball-type body, make the internal diameter and the pear funnel long tube external diameter of mastoid nob pipe form the slit, so that the acid in the pear funnel enters the ball-type body, simultaneously can prevent that the solid medicine of ball-type body from slipping in the mastoid nob pipe, New Type of Gas Generator has been saved heavy hemisphere structure, device, operation, scrub, keeping is all very convenient, and acid consumption is few, because the acid that adds can both effectively contact with solid medicine, be swift in response, the air-flow abundance is particularly suitable for the usefulness of scientific research and education experiment.
The advantage of the utility model gas generator is significantly, at first be simple in structure, device easily.It is to be connected to form by pear funnel and ball-type body, saved huge dome-type body, be fixed on the brandreth during use and get final product, it is more safer than opening general gas generator, from the side mouth adding solid medicine of ball-type body, from the adding acid suitable for reading of pear funnel, acid enters in the ball-type body and with the solid medicine reaction gas takes place, close side mouth piston, acid just is pressed into pear funnel and separates with solid medicine, and reaction stops immediately.The utility model gas generator volume is little, in light weight, and it is compared with the general gas generator of opening of effect same, only opens 1/5th of general gas generator volume, 1/10th of weight.Because the acid that adds can both enter the ball-type body and gas takes place in the solid medicine reaction, the air-flow abundance, when sluggish, can incline at any time spent acid replacing eo-acid, and operation only needs very short time, just can recover original air-flow.The mastoid nob of the utility model gas generator ball-type body bottom only holds the acid of 1-2 milliliter, only needs when producing a small amount of gas as required that the amount of gas adds acid, and acid consumption significantly reduces.
The utility model gas generator concrete structure is drawn by following enforcement and accompanying drawing thereof.
As shown in Figure 1,1. 2. 3. link with the ball-type body by pear funnel and to form with the mastoid nob of bottom, the mastoid nob pipe that 5. pear funnel long tube 1. inserts ball-type body bottom 3. in, the long tube external diameter of the internal diameter of mastoid nob pipe and pear funnel forms 3 millimeters slit, so that the acid in the adding pear funnel enters the ball-type body, prevent that simultaneously the solid medicine in the ball-type body from slipping in the mastoid nob pipe.
The utility model gas generator is to be made by glass or plastics.
Claims (4)
1, New Type of Gas Generator is the instrument that a kind of chemical experiment is used, it is characterized in that by pear funnel 1. (the belt length pipe 5.), ball-type body 2. (band side mouth 4.) and the mastoid nob pipe of bottom thereof 3. form, the main effect of mastoid nob is to replace the hemisphere part that opens general gas generator.
2, by claim 1, described structure is characterized in that 2. 1. pear funnel be sintered into one with the ball-type body.
3, by claim 1, described, pear funnel long tube 1. 5. insert the mastoid nob pipe 3. in, mastoid nob pipe internal diameter and the pear funnel slit that 1. forms 2mm～3mm between long tube external diameter 5. 3., enter the ball-type body 2. so that add the acid of pear funnel in 1., prevent that simultaneously the solid medicine in the ball-type body 2. from slipping in the mastoid nob.
4, described by claim 1, the material that it is characterized in that this instrument is that the glass or the plastics of acid and alkali resistance corrosion are made.
