Abstract
The utility model relates to a hand vacuum packing unit, comprising a guide cylinder, an end cover and a piston assembly. The utility model is characterized in that the piston assembly comprises a volume changing cylinder, a guide piston, a valve body and a handle. The volume changing cylinder is a corrugated tubular axial direction telescopic cylinder made of the air-proof flexible materials and is arranged in the guide cylinder, the left and right ends connect with the guide cylinder, the left end cover, the valve body and the guide piston in a fixed way, and the side wall of the left end of the guide cylinder is provided with a balancing hole. Through the repeated pushing and pulling operation, the vacuum pumping purpose is achieved to keep food fresh.
Description
The utility model relates to a kind of family expenses antistaling vacuum container.
The family expenses vacuum sealed package machine that present people generally use can roughly be divided into following two big classes, and the Motorized vacuum sealing and packing machine that a class is made up of vacuum pump and motor needs power supply during operation, makes complexity, and carries inconvenience; Another kind of is to be the manual vacuum packing device that primary clustering constitutes by cylinder and piston, and this device is because inevitable gap between piston and cylinder causes gas leakage, and the higher degree of vacuum of out of reach.
The purpose of this utility model provides and a kind ofly can save motor, makes its structure manufacturing simple, can overcome the family expenses manual vacuum wrapper that gas leakage between piston and cylinder reduces the defective of degree of vacuum again.
The utility model is realized by following measure:
Family expenses manual vacuum wrapper mainly is to be made of guide cylinder, two end cap and piston component, piston component comprises volume-variation tube, pilot piston, valve body and handle, the volume-variation tube that is corrugated tube shape is arranged in the guiding cylindrical shell, volume-variation tube one end is captiveed joint with the left end cap inner plane with guide cylinder, and it is an integral body that the other end and valve body and pilot piston are fastenedly connected.The volume-variation tube is to adopt garden oblique crank Z that airtight flexible material makes to telescopic corrugated tube shape tube, has a unloading hole on the guide cylinder left end sidewall, prevents to feel suffocated, and makes handle push away, draw light piece.
Description of drawings:
Accompanying drawing is a structural representation section-drawing of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
Family expenses manual vacuum wrapper is by guide cylinder 5, left end cap 1, right end cap 10 and piston component 8 constitute, piston component comprises volume-variation tube 4, pilot piston 9, valve body 6 and handle 11, volume-variation tube 4 is that the garden oblique crank Z made with flexible gas impermeable material (slim canvas filler rubber) is to telescopic corrugated tube shape tube, under the free state, its axial section indentation, the volume-variation tube is arranged in the guide cylinder 5, its left end flanging is clipped between two face of joints of left end cap 1 and guide cylinder 5, and clamp by seal ring, left end cap is fixed by negative thread and guide cylinder, on guide cylinder left end sidewall, have a unloading hole B, valve body 6 is connected with pilot piston 9 by outside thread, volume-variation tube right-hand member in-flanges is enclosed within on the flange of valve body and is clipped between the face of joint of valve body and pilot piston, clamp by seal ring, handle 11 stretches in the guide cylinder by the centre hole of right end cap 10, and be threaded with pilot piston 9, right end cap 10 is fixed by screw thread and guide cylinder right-hand member, the limit on the right-right-hand limit position of restricted guidance piston.Breather cheek valve 3 that thin rubber is made and exhaust check valve 7 are fixed on inner plane suction hole A place, left end cap right side and valve body right side deflation hole C place by screw 2 and 12 respectively, be respectively equipped with deflation hole D and E on pilot piston right side and the right end cap, but the air exhaust to atmosphere that the volume-variation tube is discharged through check valve 7.
During use, the plastic bag sack that desire preservation food will be housed is earlier entirely wrapped up on the outer garden cylinder that wraps in left end cap 1, and tighten with the rubber bar, air bleeds in the bag when preventing to vacuumize, one holds guide cylinder 5, another hand successive reciprocation drawing handle 11, at this moment pilot piston 9 is together with right-hand member crank motion in guide cylinder of volume-variation tube 4; Form the axial stretching of volume-variation tube, the cyclical variation of bore seal spatial volume, when volume-variation tube inner chamber seal cavity volume becomes big, its internal gas pressure reduces, exhaust check valve 7 is closed, breather cheek valve 3 is opened, gas in the packaging bag sucks the volume-variation tube inner chamber through the suction hole on the left end cap 1, otherwise, the gas of volume-variation tube inner chamber is through the hole of valve body 6 and the hole exhaust to atmosphere on pilot piston and the right end cap 10, said process is several repeatedly, and most of air is drawn out of in the packaging bag, makes and forms quite high degree of vacuum in the packaging bag.
The utility model has the advantage of that volume changes the variable seal cavity of volume that tube consists of, replace the variable seal cavity of volume that consists of with matched in clearance between piston and cylinder, overcome the defective that clearance leakage hinders vacuum to improve, save simultaneously motor, make its designs simplification, applicable to any power free occasion.
