Specific embodiment

The utility model is further described with specific embodiment with reference to the accompanying drawing.

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of vacuum juicer convenient to use, including base 1, the processing being connect with base Component 11, the storage juice container 2 for sealing accommodating fruits and vegetables juice are used to vacuumize adapter 3, base with what storage juice container connected The interior motor for being equipped with driving processing assembly and the vacuum pump (not shown) for vacuumizing, vacuumize adapter and pass through pumping Gas hose is connected with the vacuum pump in base.Storage juice container includes cup body 21, the sealing cover being covered on cup body 22, Setting can be covered with the connector 221 for vacuumizing the evagination that adapter is connected and after downwardly turning over and be connect on sealing cover The overturning lid 23 of mouth.Certainly, it would be desirable to check valve is set in connector, the intracorporal air of cup can not only extracted out outward, but also It can avoid external air to enter in the cup body vacuumized.

Furthermore, it would be desirable to the opposite damping plane 221 in left and right be set on sealing cover, be respectively set in damping plane Rotational pin 24, and the rotational pin of the left and right sides is coaxially positioned opposite, overturns the opposite support ring in the downside setting left and right of lid 231, support ring is socketed in the rotation pin end of corresponding side, to make overturning lid that can rotate upwardly and downwardly.Certainly, we can seal The position limiting structure that corresponding limited block etc is set is covered, so that covering overturning can be positioned on one when being rotated up more than 90 degree The open position of a fixation.

In order to avoid quickly downwardly turning over when by unintentionally touching is covered in the overturning of open position, it would be desirable to turn Dynamic pin root is arranged a flexible damping washer 4, and damping washer side reclines support ring, and the other side, which reclines, damps plane. It is understood that the outside spacing between two support rings in left and right should be greater than the spacing between the rotation pin end of left and right two, Support ring to avoid overturning lid is deviate from from rotational pin.When installation overturning lid, we can make the support ring in overturning lid left side first It is set in the end that left side is arranged with the rotational pin of damping washer, then pushes hard to the left and turns hub cap over, make the bearing in left side Ring squeezed air-damping washer, until the support ring on right side enters the region between rotational pin end face, it can be by the rotational pin on right side Set is set on the rotational pin on right side.At this point, the damping washer elastic recovery that left side is squeezed, so that overturning lid be driven to enjoy shifting It is dynamic, so that overturning lid is automatically positioned at the position among the consistent rotational pin of the damping plane of left and right two, and two damping mats in left and right Circle is squeezed by one simultaneously and is compressed, and the rate control of two damping washer thickness is then propping up between 5%-30% Meeting between the side and damping washer of carrier ring and between the damping plane and damping washer of sealing cover is simultaneously as squeezing and producing Raw certain stiction and kinetic force of friction.When overturning lid is flipped up to open position, by the static friction of damping washer Power can be effectively prevented from automatic when being touched of overturning lid and quickly downwardly turn over and collide sealing cover, be conducive to extend overturning The service life of lid.Overturning lid can be made to rest on open any position in particular, damping washer is formed by stiction, To greatly facilitate the use of juice extractor, avoids overturning from covering collision noise when spinning upside down, improve juice extractor significantly User experience.And the slight abrasion of damping washer still can make the rate control of its thickness in suitable range, into And it is maintained at resistance when overturning lid rotation on one steady state value.

When the compression ratio of damping washer thickness is less than 5%, the insufficient compression of damping washer will cause, damping washer has been difficult to To due damping action, overturning lid can not rest on open any position by frictional force.When the pressure of damping washer thickness Shrinkage is greater than 30%, will cause the excess compression of damping washer, has both caused the difficulty of overturning lid installation, while will cause overturning lid Frictional force is excessive when rotation, is unfavorable for the rotation of overturning lid.

It should be noted that support ring and the connection structure of rotational pin can there are many other forms, for example, we can One chamfering is set with the lower part on the outside of first support ring, or rotates the upside setting one of pin end at first Angle can firmly push overturning lid, at this time first bearing when second support ring set is set on corresponding rotational pin by we Ring can under the action of chamfering bending deformation and squeeze into two rotation pin end between regions, and finally set be set to first On rotational pin.Alternatively, the opening less than rotational pin diameter can also be arranged in we in first support ring, when second support ring When set is set on rotational pin, overturning lid can be firmly squeezed, makes the opening distending of first support ring and covers and be set on rotational pin.This The compression ratio of damping washer thickness refers to the ratio of decrement and original thickness in embodiment, for example, original thickness is H, compression Afterwards with a thickness of h, then compression ratio is equal to (H-h)/H.

The silica gel that food-grade preferably can be used in damping washer is made, and the shore hardness of damping washer is controlled in 30- Between 55.Since juice extractor needs repeatedly to rotate overturning lid in use, and elasticity is good for silica gel, has good wear-resisting Property, ageing resistance, therefore, the damping washer made of silica gel still can maintain enough elasticity after prolonged use, make to turn over Hub cap has enough rotary dampings, thus has good feel in rotation, while facilitating its assembling.When damping washer When shore hardness is less than 30, under the identical thickness reduction of damping washer, excessively soft damping washer will lead to overturning lid rotation When damping it is too small, overturning at this time lid is difficult reliably to rest in open position；When the shore hardness of damping washer is greater than When 55, damping washer is really up to the mark, is unfavorable for the compression of damping washer in the assembling of overturning lid.Due to the damping washer after assembling Compression ratio is difficult to reach design requirement, therefore the elastic force generated after its compression and corresponding frictional force are difficult to meet design and want It asks.

As a preferred embodiment, a U-shaped groove 222 is arranged in the upside of sealing cover, and one end of the U-shaped groove is semicircle The closed end of shape, the other end then extend towards the edge of sealing cover, until perforation sealing cover edge, thus in the upside of sealing cover And lateral formed is open.Correspondingly, the connector on sealing cover is arranged in U-shaped groove, and damps plane and be then respectively set In U-shaped groove in the two side walls of semicircular closed end.Overturning lid fits in opening on the upside of U-shaped groove, and Overturning covers one end far from support ring and the baffle 25 extended downwardly is arranged, and baffle fits in the lateral opening of U-shaped groove, thus The lateral opening of sealing cover is covered, being conducive to, which makes to seal cap surface, keeps smooth beauty.When we need to be rotated up overturning lid When, overturning can be pushed up against and cover the baffle for fitting in the lateral opening of U-shaped groove, thus the unlatching for facilitating overturning to cover.

As shown in figure 4, storing for convenience, we can be arranged in the side wall of base by the local receiving formed that is recessed inwardly Chamber 12 vacuumizes adapter and then fits in accommodating chamber.Certainly, corresponding buckle can be arranged at the edge of accommodating chamber in we, with Just make to vacuumize adapter and reliably be connected in accommodating chamber.

For the ease of the control to vacuum pump, we can correspond in base is arranged normally opened control switch 5 at accommodating chamber, Control switch is electrically connected with vacuum pump, in order to control the opening and closing of vacuum pump.In addition, we can vacuumize adapter and receiving The trigger architecture that can trigger control switch is set between chamber, and when vacuumizing adapter and being accommodated in accommodating chamber, trigger architecture is risen Effect, so that control switch be made to close, vacuum pump at this time is not necessarily to work；It, can when we need to store up juice container vacuum-pumping It is removed from accommodating chamber and vacuumizes adapter, and be sealed against being connected on storage juice container, trigger architecture at this time does not work, Control switch is restored to normally open, the i.e. automatic starting of vacuum pump, so that the automatic control of vacuum pump can be realized, so as to effective Ground avoids causing working long hours for vacuum pump because user forgets shutdown, is conducive to extend the service life of vacuum pump.

Preferably, trigger architecture include the guide pipe 13 being arranged in corresponded in base at accommodating chamber on inner sidewall, setting exist The outer touching of perforation guide pipe is arranged in accommodating chamber bottom in triggering rod 6 in guide pipe, the reset spring 7 being set on triggering rod Bar via hole 121 corresponds to the switch bracket 8 that setting is fixed in base at guide pipe in base, and control switch, which is then arranged, to be opened It closes in bracket, the interior feeler lever via hole 81 coaxial with guide pipe is set on switch bracket.In addition, being arranged on the lateral wall of triggering rod The limit shaft shoulder 61 of one circle diameter convex, to being separated into triggering rod close to the inner end of control switch and close to accommodating chamber Outer end.Reset spring is set on the inner end of triggering rod, and the outer end of triggering rod fits in guide pipe.The one of reset spring End compresses the limit shaft shoulder, and the other end compresses switch bracket, so that outer feeler lever is stretched out in the outer end for fitting in triggering rod in guide pipe Via hole.

When we, which will vacuumize adapter, puts into accommodating chamber, vacuumizes adapter and inwardly push outside triggering rod stretching The inner end of the outer end of feeler lever via hole, triggering rod compresses and triggers control switch, and control switch is made to switch to closed state；When us From accommodate it is intracavitary remove vacuumize adapter when, reset spring is displaced outwardly triggering rod, and the inner end of triggering rod is left control and opened It closes, control switch at this time switches to opening state.It is understood that we can expose to accommodating chamber bottom by pressing manually The triggering rod outer end in portion, the easily opening and closing of point operation control vacuum pump, to control the vacuum degree of storage juice container as needed.It needs It is noted that normally opened microswitch preferably can be used in control switch, it is known that have can self-resetting for microswitch Drive rod 51, when triggering rod depresses drive rod, microswitch switches to closed state；When triggering rod leaves drive rod When, drive rod self-resetting and switches to opening state at microswitch at this time.

As another preferred embodiment of trigger architecture, as shown in figure 5, trigger architecture includes that setting is vacuumizing adapter On triggering rod 6, the outer feeler lever via hole 121 of accommodating chamber bottom Yu the drive rod corresponding position is set.It transfers when vacuumizing When head is put into accommodating chamber, interior feeler lever of the triggering rod on outer feeler lever via hole and switch bracket on adapter is vacuumized Via hole simultaneously contradicts drive rod, and microswitch at this time is in close state；When vacuumizing adapter and leaving accommodating chamber, fine motion is opened The drive rod of pass resets, and microswitch at this time is in the open state.In the present solution, we directly on vacuumizing adapter Triggering rod is set, thus be conducive to simplify the structure and assembling of base, and triggering rod is fixed structure, without resetting, because And the reliability of trigger architecture work can be improved.

In order to improve the sealing performance of storage juice container, as shown in Fig. 2, we can make the lower part of sealing cover locally to downward The auxiliary section 223 to be formed and be protruded into cup body opening is stretched, and is arranged in the outside of auxiliary section closely against cup body opening inner side wall Lateral seal muscle 224 is interference fitted so that lateral seal muscle and cup body opening inner side wall be made to be formed.When we close sealing cover lid When on to cup body, auxiliary section enters in cup body opening, thus make sealing cover and cup body automatic centering, and lateral seal muscle is then in cup Lateral seal is formed between body and sealing cover.It should be noted that we can make the opening inner side wall formation mouth imperial palace of cup body small Cone, correspondingly, the lateral wall of auxiliary section is the cone gradually reduced from top to bottom.In this way, when auxiliary section enters When in the opening of cup body, lateral seal influential point of tendons moves closer to the inner sidewall of cup body opening, until lateral seal muscle and cup body are open Inner sidewall forms interference fit, to facilitate the assembly and disassembly of sealing cover.

Preferably, lateral seal muscle and the magnitude of interference of cup body opening are can be controlled between 0.3-0.8mm, not only improve raising Sealing effect between the two, and sealing cover lid is facilitated to close onto cup body.When the magnitude of interference that lateral seal muscle and cup body are open is small When 0.3mm, lateral seal effect between the two can be reduced；When the magnitude of interference that lateral seal muscle is open with cup body is greater than When 0.8mm, then sealing cover lid can be made to close, and resistance when onto cup body is excessive, so that the lid for being unfavorable for sealing cover closes.

It is threadedly coupled in addition, sealing cover is used with cup body, while also the vertical close of annular can be set in the downside of sealing cover Muscle 225 is sealed, vertical seal muscle closely compresses cup body open end.Vertical seal when sealing cover lid closes in place, under sealing cover Influential point of tendons closely compresses cup body open end, to form end face seal together, between cup body and sealing cover to further increase Sealing effect between sealing cover and cup body.Preferably, when sealing cover lid closes in place, vertical seal muscle and cup body open end Between magnitude of interference between 0.3-1mm, to ensure to form reliable end face seal between the two.When vertical seal muscle and cup When magnitude of interference between body open end is less than 0.3mm, the end face that too small magnitude of interference can reduce between sealing cover and cup body is close Seal effect；When the magnitude of interference between vertical seal muscle and cup body open end is greater than 1mm, then it can increase lid and sealing significantly Lid resultant force needed for lid makes sealing cover be not easy lid and closes in place.In particular, when we close sealing cover lid in place, it is excessive Magnitude of interference be easy that vertical seal muscle is made to occur being plastically deformed and damaging.
