Description
Technical field
The utility model relates to air extractor, particularly a kind of air extractor of double barreled vacuum bag.
Background technique
Vacuum bag is a kind of storage bag commonly used, generally disposes vacuum suction device.At present existing air extractor all is made up of the pump bowl and the mouth of bleeding, and the technical problem of its existence has a variety of, and for example: the pump bowl and the mouth of bleeding cooperate not tight, easily gas leakage; Pump bowl cooperates by direct-insert mode with the mouth of bleeding, and rely on the deformation pressure of material to prevent gas leakage, but pump bowl is thrown off easily when the action of bleeding takes place, causes the inconvenience of using with the mouth of bleeding; Bleed position is fixed in pumping process, is not easy to physical activity, and pumping process is relatively required great effort.And existing air extractor all is the monotubular formula, and rate of air sucked in required is less, use relatively require great effort time-consuming.
Summary of the invention
The purpose of this utility model provides a kind of convenience of bleeding, is difficult for gas leakage, and time saving and energy saving double barreled vacuum bag air extractor.
The air extractor of described a kind of double barreled vacuum bag comprises handle, piston, pump bowl and the head of bleeding, it is characterized in that: described pump bowl is a double barreled, be provided with piston at each pump bowl, the head of bleeding is tightly connected successively by the valve joint of the air pump joint of hollow type, sebific duct, hollow type and valve and forms, and the sealing channel that is communicated with pump bowl of formation; The upper end of two pump bowls is provided with sealed type diplopore dished cover, and the pull bar of two-piston passes the diplopore dished cover respectively and handle is tightly connected, and the lower end of two pump bowls is connected by the air pump joint screw thread of the recessed lid of single hole with the head of bleeding.
Described handle is horizontal D type, is that the hand surface of contact is the male and fomale(M﹠F) that coincide with finger.
The diplopore symmetry of described diplopore dished cover is opened on the dished cover face, and the single hole of the recessed lid of single hole is opened on the recessed capping.
The outer rim of described valve joint and valve is the lace shape structure.
The position that described piston is connected with handle is the frustoconic shape structure.
The beneficial effects of the utility model: 1. increase that to make double pump tube rate of air sucked in required into by original single pump barrel bigger, save time and laborsaving;
2. increased joint and sebific duct air pump, can move up and down when bleeding, more laborsaving to the active actions of human body;
3. appearance design is more reasonable, technology simpler simple in structure in addition, dismounting is also more convenient, easy processing.
The utility model good sealing effect can prevent to produce in the pumping process gas leakage better, further improves the efficient that vacuumizes, and time saving and energy saving; It is simple in structure, and beautiful shape uses more convenient, fashion.

Among the figure: 1-pump bowl, 2-piston, 3-diplopore dished cover, 4-handle, the recessed lid of 5-single hole, 6-air pump joint, 7-sebific duct, 8-valve joint, 9-valve.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.Among Fig. 1,2, the air extractor of described a kind of double barreled vacuum bag, comprise handle, piston, pump bowl and the head of bleeding, it is characterized in that: described pump bowl 1 is double barreled, be provided with piston 2 at each pump bowl 1, the head of bleeding is tightly connected successively by the valve joint 8 of the air pump joint 6 of hollow type, sebific duct 7, hollow type and valve 9 and forms, and the sealing channel that is communicated with pump bowl 1 of formation; The upper end of two pump bowls 1 is provided with sealed type diplopore dished cover 3, and the pull bar of two-piston 2 passes diplopore dished cover 3 respectively and is tightly connected with handle 4, and the lower end of two pump bowls 1 is threaded by the air pump joint 6 of the recessed lid 5 of single hole with the head of bleeding; The recessed lid of dished cover and lower end of pump bowl upper end has strengthened go back to power space, can make when bleeding more laborsavingly, and rate of air sucked in required is big.
Described handle 4 is horizontal D type, is that the hand surface of contact is the male and fomale(M﹠F) that coincide with finger, holds comfort level for strengthening holding sense, increasing.
The diplopore symmetry of described diplopore dished cover 3 is opened on the dished cover face, and the single hole of the recessed lid 5 of single hole is opened on the recessed capping.
Among Fig. 3,4, the outer rim of described valve joint 8 and valve 9 is the lace shape structure, and is both attractive in appearance, can save material again.
The position that described piston 2 is connected with handle 4 is the frustoconic shape structure, makes installation more convenient, should not come off.
As Fig. 4, valve 9 bottoms that the utility model adopted are provided with dividing plate, the dividing plate outer wall is interval with triangle skeleton, on the dividing plate between the adjacent triangle skeleton, offer air outlet hole, between adjacent skeleton, form air-flow path like this, the air of being convenient in the vacuum bag is extracted out from air-flow path smoothly, and present embodiment intermediate cam shape skeleton is not only saved material, and is convenient to the smooth circulation of air.
During work, earlier storing is placed in the vacuum bag, after sealing sack, the valve joint 8 of pump bowl 1 with air pump joint 6, sebific duct 7, hollow type is sealedly connected and fixed successively, and screw by mouth 9 screw threads of bleeding on screw thread and the vacuum bag, form a sealing bleed-off passage that vacuum bag is communicated with pump bowl 1; Promote handle then, just the air in the vacuum bag is extracted out by sealing channel.
The utility model adopts the technological scheme of the pump bowl and the mouth threads engaged of bleeding, and can prevent to produce in the pumping process gas leakage better, further improves the efficient that vacuumizes; And the employing bitubular, increased rate of air sucked in required, accelerated the time of bleeding.
