Under the premise of degree, it is very crucial for promoting the efficiency of gas chamber cleaning.Inventors believe that by designing cube convenient for cleaning
Bodily form gas chamber, for example, if especially double tail pipe structures are arranged in side corner, compared to biography on the side of cube cavity
The gas chamber of single tail pipe positioned at center side of system can not only promote the cleanliness of gas chamber cleaning, enhance the anti-relaxation property of gas chamber
Energy；Can cube shaped alkali metal gas chamber can also be injected and is discharged the convection type cleaning of cleaning solution, simplification was cleaned
Journey improves cleaning efficiency, saves scavenging period, has huge application prospect.In view of this, the present inventor completes this hair
It is bright.
Summary of the invention
The present invention is in view of the deficiencies in the prior art or insufficient, provides a kind of cube shaped convenient for double tail pipes of cleaning
Alkali metal gas chamber can not only be eliminated by the way that on the side of cube cavity, especially double tail pipe structures are arranged in side corner
Zonule cleaning liquid inside residual centered on cube apex, moreover it is possible to alkali metal gas chamber be carried out before filling alkaline metallic atom
The convection type cleaning of injection and discharge cleaning solution simplifies gas chamber cleaning stream to be conducive to while promoting gas chamber cleanliness
Journey improves the efficiency of alkali metal gas chamber cleaning, saves gas chamber scavenging period.Can to avoid due to gas chamber it is unholiness caused by relax
Henan promotes the anti-Relaxivity of gas chamber, greatly promotes the production quality of gas chamber.
Technical solution of the present invention is as follows:
The cube shaped alkali metal gas chamber of a kind of double tail pipes convenient for cleaning, which is characterized in that including gas chamber transparent glass shell
Body, the gas chamber transparent glass shell is in cube shaped, on the opposed facing side wall of a pair of the gas chamber transparent glass shell
It is provided with tail pipe, the tail pipe is connected to gas chamber inner cavity.
The tail pipe is arranged on sidewall corners.
The gas chamber transparent glass shell includes upper side wall, lower wall, front side wall, rear wall, left side wall and right side wall, institute
It states the sidewall corners on upper side wall and is provided with the first tail pipe, the sidewall corners in the lower wall are provided with the second tail pipe, described
First tail pipe and the second tail pipe are circular configuration, and first tail pipe and the second tail pipe pass through circular hole and gas chamber inner cavity company
It is logical.
First tail pipe is perpendicular to the upper side wall, and second tail pipe is perpendicular to the lower wall.
The periphery of first tail pipe each is tangent with the outer surface of the rear wall and the outer surface of the left side wall.
The periphery of second tail pipe each is tangent with the outer surface of the rear wall and the outer surface of the left side wall.
The circular hole each is tangent with the inner surface of the rear wall and the inner surface of the left side wall.
First tail pipe is cleaning solution pressurization inlet, and second tail pipe is cleaning solution outlet.
Technical effect of the invention is as follows: the present invention is a kind of cube shaped alkali metal gas chamber of double tail pipes convenient for cleaning,
Since on the cube shaped opposed facing side wall of alkali metal gas chamber, especially sidewall corners use double tail pipe structures, not only
The zonule cleaning liquid inside residual centered on cube apex, which can be eliminated, can also realize cleaning solution in the disengaging point of gas chamber
Stream forms cleaning solution convection effect in entire gas chamber, have efficiently, quickly, the high advantage of cleanliness.
The configuration of the present invention is simple, design rationally, by designing gas chamber tail pipe in the corner of side wall, are convenient for cube shaped alkali
The cleaning in region of the metal air chamber centered on 8 vertex enhances cleaning effect, clean in promotion gas chamber cleaning by convection effect
The cleaning efficiency of gas chamber can be significantly improved under the premise of cleanliness, save scavenging period,.In use, using peristaltic pump to first
Tail pipe applies pressure, and the second tail pipe is discharged cleaning liquid, the efficiency of cleaning can be improved, and during avoiding conventional clean, uses
Secondary pollution caused by syringe is sucked out saves and cleans the time used, promotes the cleanliness of cleaning, alkali metal gas chamber can be enhanced
Anti- Relaxivity.
