This vacuum pump can be considered lid, fixed piston assembly, sliding cylinder assembly, transition rings assembly four parts composition.Their characteristics are: 1, the fixed piston assembly can only left rotation and right rotation, can not perpendicular movement.2, the sliding cylinder assembly is can left rotation and right rotation, again can vertical up and down movement.3, transition rings assembly can only vertical up and down movement, can not left rotation and right rotation.4, lid can not left rotation and right rotation, can not up-and-down movement.Through above tetrameric working in coordination, can ideally finish and become each row function surely, concrete mode of operation is following:
When the needs vacuum state: will go to work indicating ring vacuum position by hand; When acting on fixed piston and press hand by the two ends elastic force of retracing spring; Press hand by jack-up, be connected with four protruding buttons 301 of sliding cylinder, drive on the whole sliding cylinder assembly and carry by four recessed buttons 401 of hand.This air pump form is the air transport air pump, and promptly the piston cydariform bulge loop 203 of piston component is blocked by the annular buckle 105 of lid 1, and piston component can only left rotation and right rotation, can not up-and-down movement, and lean on and do vertically by the hand-motion cylinder assembly that back and forth movement reaches the purpose of bleeding.When the spring that is reset by hand is upspring, end in contact under sliding cylinder intracavity bottom and the fixed piston, this moment, the volume of cylinder operation chamber was 0.By subordinate on time; The promotion sliding cylinder is descending, and piston O shape was enclosed 15 outers and was close to the sliding cylinder inwall this moment, and O shape ring recess 201 lower edges of fixed piston 2 are close in the lower edge; The outer wall of the cavity axis 104 of lid 1 is close on the interior edge of cylinder O shape circle 16, and the limit, outer of sliding cylinder endoporus is close in its upper edge.305 pore outers of sliding cylinder 3 are close on the last plane of silica gel check valve; The air pump operating room is in the sealed vacuum negative pressure state; The operating room communicates with valve 8 upper ends through fixed piston air drain, shift fork 204, and valve 8 upper ends produce negative pressure, carry on the valve and opening; The fast flow speed and direction air pump of the air drain operating room of the pore 1104 of the pore 108 of the air in the storage box body 17 through lid 1, silicagel pad 11, the valve edge 803 of valve 8 and the gap between the silicagel pad, fixed piston 2 reaches balance very soon.The elastic force of retracing spring 14 makes by hand-motion sliding cylinder assembly fast uplink and resets when loosening by hand; The upper edge of piston O shape circle 15 relies on O shape ring recess 201 upper edges of fixed piston 2 in up process; It is interior along the limit 701 that the lower edge of cylinder O shape circle 16 relies on snap ring 7; The cylinder operation chamber is through the crest clearance of sliding plug with the axis 104 of cylinder inner wall gap, cylinder bore and lid, and the cylinder operation chamber communicated with outer Jie, and operating room's internal gas pressure is replied normal.It is negative pressure state that air exhaustion is arranged in the depository dish; Drive the valve return, this moment, the upper end of valve was a normal barometric pressure, and the lower end is a negative pressure; The pressure of valve upper and lower side generation difference of pressure acts on the axis inner chamber bottom surface of valve edge 803 and silicagel pad 11 and lid 1, makes valve reach envelope gas purpose.This action frequency that circulates is many more, and the negative pressure in the depository dish can be big more, can be near reaching vacuum effectiveness.
When the vacuum completion needs to preserve; By the hand spring jack-up that still is reset; Pressing hand needs left-hand revolution to reset position, when pressing the hand-screw commentaries on classics, makes the and then rotation of fixed piston assembly by the protruding key 207 of inner chamber on the recessed key 405 drive fixed pistons of hand 4 axis 2 axis; Link to each other with four protruding keys 301 of sliding cylinder 3 owing to press four recessed keys of hand 4, sliding cylinder is rotation synchronously also.Having only the both wings 605 of transition rings 6 to be contained in the cavity keyway 102 of lid 1 can not rotate; It can only lean on transition rings endoporus limit and the rotation of sliding cylinder base circle buckle 302 outer walls; Owing to press hand, fixed piston assembly, sliding cylinder rotation; Transition rings is not rotated, and the spring shift fork that is contained on the transition rings is stirred by the bottom round boss 304 of sliding cylinder 3, when the spring shift fork pushes the center; Because action of the spring can be bound to reset position automatically, this moment, shift fork 306 rights crus of diaphragm of sliding cylinder 3 bottoms climbed 1001 near torsion spring 10.Because of the two-way function of spring shift fork and torsion spring, the location can be very accurate.Work the in addition two sides of back-off 501 of indicating ring 5 are stuck in the both wings shift fork 606 of transition rings 6; Transition rings can not changeed with the work indicating ring when changeing by hand-screw; The back-off 501 of the shift fork 605 of transition rings and work indicating ring 5 can only and be pressed in the arc-shaped through-hole 403 of hand 4 and move at the arc-shaped through-hole 307 of sliding cylinder 3.Non-return air valve and 305 dislocation of sliding cylinder 3 bottom pores, by subordinate on time, air can get into the air pump operating room from pore 305, can not produce vacuum state, can be very like a cork by on earth.The elasticity of sliding cylinder 3 bottoms is colluded and is climbed the 303 protruding buttons 103 that can catch in lid 1 cavity, just can be returned to original position like a cork by hand.
During the keeping-freshness storage, be vacuum state in the box chamber, take out the storage object like need, exit earlier, lid just can be opened.Like the need venting,, can get back to vacuum position automatically by hand as long as stop a little pressing hand dextrorotation to deflation position.When pressing hand-screw to deflation position; By by hand-motion fixed piston component synchronization rotation, the helical surface of the spiral both wings 801 of valve 8, left-hand screw boss 106 helical surfaces of being close to the axis intracavity bottom both sides of lid 1 jack-up that makes progress; The valve edge 803 of valve 8 are separated with the inner chamber bottom surface of silicagel pad 11; Air gets into from the bottom pore 305 of sliding cylinder, through the air drain of cylinder operation chamber, fixed piston 2, valve edge 803 and the Separation of the inner chamber bottom surface of silicagel pad 11, the pore 114 of silicagel pad 11, the pore 108 of lid 1 of valve 8, gets into depository dish fast; Reach balance very soon, reach the venting purpose; When pressing hand-screw to the venting position; Drive the sliding cylinder rotation simultaneously by hand, the bottom round boss 304 of sliding cylinder 3 will be stirred the spring shift fork earlier to vacuum position; This moment, the left foot of bottom shift fork 306 of sliding cylinder 3 climbed 1001 near torsion spring 10; During clickwise, the left foot of the bottom shift fork 306 of sliding cylinder drives 1001 rotation together of climbing of torsion spring 10 again, is blocked by pit 608 sides of transition rings 6 because another of torsion spring 10 climbs 1001; The shock damping action of torsion spring elastic force need be exerted oneself during rotation a little.After treating that venting is accomplished, unclamp and press hand, get back to vacuum position automatically because the screen resilience of torsion spring can make by hand.This moment, lid can easily be opened.
The hand push type vacuum pump fixedly is installed in the lid cavity; Need after the use often to clean; Only need when needing to clean and will rotate to cleaning positions by the hand conter clockwise, under the drive of pressing hand, sliding cylinder, fixed piston assembly rotate together; The helical surface of the axis lower end right-hand screw step 206 of fixing sliding plug 2; The helical surface of right-hand screw boss 107 of intracavity bottom of being close to the axis 104 of lid 1 jack-up that makes progress, the axis cydariform bulge loop 203 that makes fixed piston 2 breaks away from the annular buckle in axis upper end of lid 1, and air pump promptly separates with lid.When pressing the hand-screw commentaries on classics, the right crus of diaphragm of the bottom shift fork 306 of sliding cylinder drives 1002 rotation together of climbing of torsion spring 10 simultaneously, and the other end 1001 of torsion spring 10 is blocked by pit 608 sides of transition rings 6; Climb 1002 to climb 1001 near; The shock damping action of torsion spring elastic force need be exerted oneself during rotation a little, behind the air pump to be removed; Because the screen resilience of torsion spring can make by hand and get back to reset position automatically.Can fixed piston 4 be shifted onto the bottom of sliding cylinder 3 by hand spring 14, the axis of fixed piston is exposed to outside, sliding cylinder bottom, can easy removal silicagel pad 11 and valve 8.Take out the silica gel sealing ring 13 in the annular seal groove 109 of lid 1 again.The lid 1 that need to clean this moment, box body 17, silica gel sealing ring 13, silicagel pad 11, valve 8, all be discrete item, clean very convenient.
After treating clean drying; Need back dress, because of silica gel is soft elastic material, mounting or dismounting all can free-handly be operated; Put into lid 1 annular seal groove 109 to silica gel sealing ring 13; The back-off axis 1101 of silicagel pad 11 is packed in the mesopore step 802 of valve 8, and the spiral both wings 801 of valve 8 and the positioning table of silicagel pad 11 1103 be the shift fork 204 of secured in alignment piston 2 simultaneously, gets final product pack into the circular groove 205 of fixed piston 2 of the annular groove 1102 of silicagel pad again.Aim at the both wings of transition rings 6 604 the cavity keyway 102 of lids 1 again, the axis 202 of fixed piston 2 is aimed at the axis inner chamber of lids 1, and downwards firmly by on earth, the axis cydariform bulge loop 203 that makes fixed piston 2 is pressed into the annular chuck 105 of lid 1 and gets final product.
After vacuum is accomplished, forward to by hand-screw in the process of reset position, there are plane and plane friction in the axis inner chamber bottom surface of the outer wall bottom surface of silicagel pad 11 and lid 1, but can not leak gas.In rotating to the reset position process, the spiral both wings 801 of valve 8 are in neutral, to rotate by hand, can not contact with 107 with two pairs of left and right sides spiral boss 106 in axis chassis of lid 1.When needing to clean air pump assembly, its in-to-in retracing spring 14 is made with torsion spring 10 usefulness corrosion-resistant steels, and other part is rubber and Plastic Parts all, is not afraid of washing, and is not perishable.
