Said first abaculus is based in the lateral wall in the caulking groove; The second abaculus root is based in the joint outer periphery.

Said collecting bag is made up of collecting bag body, bag opening, the chimeric strip of paper used for sealing of sack.

Have step through-hole on the said valve body, valve sheet places two limits of step through-hole and valve sheet to place on the step of step through-hole, and the valve cover of band air extractor vent is spirally connected and is fixed on the valve body.

Form elbow on the said joint, the elbow sleeve is in flexible pipe, and the elbow passage communicates with flexible pipe and step through-hole; The aspiration column body is made up of cylindrical shell, piston, piston rod and handle, and piston and piston rod are fixed together and place cylindrical shell, and piston rod passes cylindrical shell and handle is fixed together,

Aspiration column body bottom is fixed with the aspiration column noumenal seat, forms left opening and right opening on the aspiration column noumenal seat, and left opening and right opening and aspiration column body connect, and in the left opening check valve are installed, and right opening connects flexible pipe.

The beneficial effect of the utility model is:

Its aspiration column cooperates with blow off valve closely, and exhaust efficiency is high, can on-line operation after simultaneously aspiration column and blow off valve being docked, need not save time and save trouble by hand according to the joint of aspiration column; Its blow off valve good seal performance of while.

The specific embodiment:

Embodiment: see shown in Fig. 1～7; The exhaust improvement of the collecting bag and the rod of bleeding; Comprise a collecting bag 1, a blow off valve 2 and the aspiration column 3 that is used with blow off valve 2; The one-way exhaust valve that blow off valve 2 is made up of a valve body 21 and a valve sheet 22 is provided with the caulking groove 213 of a loop shaped in valve body 21 upper ends, the sidewall in caulking groove 213 is equipped with several first abaculus 214;

Aspiration column 3 has a joint 32 and combines with aspiration column body 31 to form via a flexible pipe 33; Joint 32 is " ㄇ " female cap shape; The peripheral process of joint 32 is provided with several second abaculus 321 that matees first abaculus 214; Joint 32 sleeves are in caulking groove 213, and second abaculus 321 is fastened on the bottom of first abaculus 214.

Said first abaculus 214 is based in the lateral wall in the caulking groove 213; The second abaculus root 21 is based in joint 32 outer periphery.

Said collecting bag 1 is made up of collecting bag body 11, bag opening 12, the chimeric strip of paper used for sealing 13 of sack.

Have step through-hole 211 on the said valve body 21, valve sheet 22 places two limits of step through-hole 211 and valve sheet 22 to place on the step of step through-hole 211, and valve, the lid 212 of band air extractor vent are spirally connected and are fixed on the valve body 21.

Form elbow 322 on the said joint 32, elbow 322 sleeves are in flexible pipe 33, and elbow passage 323 communicates with flexible pipe 33 and step through-hole 211; Aspiration column body 31 is made up of cylindrical shell 311, piston 312, piston rod 313 and handle 314, and piston 312 is fixed together and places cylindrical shell 311 with piston rod 313, and piston rod 313 passes cylindrical shell 311 and is fixed together with handle 314,
