Lower port side be equipped with notch, the upper end of appendix passes through the top for blocking room, and appendix upper end is connected by rubber sleeve draws
Water pipe.
As a further solution of the present invention: the appendix, aqueduct and exhaust pipe are all glass tubes.
It is respectively used to block as a further solution of the present invention: being fixed on the oral area of the tank body by rope
Appendix nozzle and enter the piston of tracheae.
The utility model has the beneficial effects that the present apparatus prevents suck-back phenomenon when can preferably be placed on inflation, together
When can preferably save nitrogen.
The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description
In become obvious, or recognized by the practice of the utility model.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment

Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model appendix lower end side figure.
In figure: 1- tank body, 2- cover, 3- enter tracheae, 4- exhaust pipe, 5- and block room, 6- floating plug, 7- bubble, 8- protrusion, 9-
Appendix, 10- notch, 11- rubber sleeve, 12- aqueduct, 13- rope, 14- piston.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1~2, in the utility model embodiment, a kind of nitrogen suck-back device, including tank body 1, tank body 1
Top is equipped with cover 2, and the oral area of tank body 1 is arranged in cover 2, and cover 2 and tank body 1 are tightly connected, and the cover 2 is equipped with and is filled with
Nitrogen enters tracheae 3.
The present apparatus the difference is that, the exhaust pipe 4 placed vertically is equipped in the tank body 1, under the exhaust pipe 4
End is located at the bottom of tank body 1, the upper end of exhaust pipe 4 pass through cover 2 and be connected to the inner cavity for blocking room 5 and 4 upper port of exhaust pipe and
The upper surface of cover 2 is concordant, and 2 upper surface of cover, which is sealedly and fixedly connected, the closure room 5 of anti-suck, and the closure room 5 of anti-suck is
Hollow, inverted truncated conical shape is equipped with floating plug 6 in the closure room 5 of anti-suck, bubble 7 is had in floating plug 6, floating plug 6 is to fall
The truncated conical shape set, the front end face diameter of floating plug 6 are less than the front end face diameter of closure 5 cavity of room of anti-suck, after floating plug 6
End face diameter is greater than the rear end face diameter of closure 5 cavity of room of anti-suck, and the lower surface of the floating plug 6 is equipped with protrusion 8, protrusion 8
Positioned at 4 upper port of exhaust pipe top and matched with the diameter mouth of upper port, it is described block room 5 upper surface appendix 9 is installed,
