Specific embodiment
In order to be able to further appreciate that structure of the present utility model, feature and other purpose, in conjunction with appended preferred embodiment
Describe in detail as follows, illustrated preferred embodiment is merely to illustrate the technical solution of the utility model, and non-limiting practicality
New.
Specific embodiment of the present utility model is as follows：
As shown in Fig. 1 is to 5, lever triangle amplifies piezoelectric stack pump, including the pump housing 1 of hollow, is provided with piezoelectricity in the pump housing 1
Stack 2 and raise one's arm 3 by what piezoelectric stack 2 drove.
Feeding mouth 1.1 and pump discharge 1.2 is provided with the pump housing 1, pump discharge 1.2 is alignd with 3 front end of raising one's arm.
Liquid enters and is full of the inner chamber of the pump housing 1 from feeding mouth 1.1, and piezoelectric stack 2 drives 3 reciprocally swingings of raising one's arm, and stirs
The liquid of its front end, liquid is released from the pump discharge of 3 front end alignment of raising one's arm, realizes the pumping of liquid.
In order to strengthen raise one's arm 3 amplitude of fluctuation, thus improving pump liquid amount, lever triangle enlarger is installed in the pump housing 1
Structure 4.
Lever triangle enlarger 4 symmetrical configuration, top 3 contacts with raising one's arm, including Triangular Arm 5, lever arm 6, fulcrum bearing 7
With actuating arm 8.
Triangular Arm 5, lever arm 6 and fulcrum bearing 7 are all symmetrical arranged two.
Hinged between the top of Triangular Arm 5, between Triangular Arm 5, be in angle is less than 180 degree.
Lever arm 6 outer end is hinged with the bottom of Triangular Arm 5, inner hinged with fulcrum bearing 7.
Fulcrum bearing 7 is affixed with the pump housing 1.
Actuating arm 8 is contacted with piezoelectric stack 2, and two ends are passed through connecting rod 9 respectively and are connected with the middle part of corresponding lever arm 6.
Piezoelectric stack 2 is energized, and produces vertical deformation, promotes actuating arm 8 to move up, drives lever arm 6.
Lever arm 6 is as lever construction, because the inner of lever arm 6 is hinged with fulcrum bearing 7, the displacement of lever arm 6 outer end
More than inner displacement.Actuating arm 8 drives the middle part of lever arm 6, displacement and the lever arm 6 affixed with it that actuating arm 8 produces
The displacement at middle part is identical, and the displacement that lever arm 6 outer end produces then is more than the displacement at lever arm 6 middle part, is then more than actuating arm 8
The displacement producing.So actuating arm 8 produces less displacement, lever arm 6 outer end can be made to produce larger displacement, produce one-level
Amplification effect.
The outer end of lever arm 6 promotes Triangular Arm 5 further, and two Triangular Arms 5 in angle form triangular structure.Due to
The outer end of lever arm 6, to medial movement, makes two Triangular Arms 5 to contract, and makes the top of two Triangular Arms 5 upwardly,
Produce two grades of amplification effects.
Upwardly raise one's arm in the middle part of 3 in the top of Triangular Arm 5,3 front ends that make to raise one's arm are swung up.Due to raising one's arm, 3 rear portions are fixed
Or hinged, the displacement of 3 front ends of raising one's arm is more than the displacement at 3 middle parts of raising one's arm, and produces three-level amplification effect.
Raise one's arm after 3 front ends are swung up, piezoelectric stack recovers, 3 itself swing the elastic force producing by raising one's arm, make to raise one's arm 3
Front end swung downward, drives all parts playback of lever triangle enlarger 4, then piezoelectric stack 2 is once again powered up, produces perpendicular
To deformation, 3 front ends that make again to raise one's arm are swung up.
Move in circles work in the manner described above, and making to raise one's arm 3 constantly swings up and down, and forms vibration.Piezoelectric stack 2 deformation is produced
Raw displacement amplitude is strengthened by lever triangle enlarger 4, and pass to raise one's arm 3 front end, increased 3 energy stirring water of raising one's arm
Power, improves pump output.
Pin joint between Triangular Arm 5, between Triangular Arm 5 and lever arm 6, between lever arm 6 and fulcrum bearing 7 all can adopt
Flexible hinge, due to the property of flexible hinge itself, when piezoelectric stack summit restores to the original state, can make thick stick by flexible hinge
The Triangular Arm 5 of bar triangle enlarger 4, lever arm 6, fulcrum bearing 7 and actuating arm 8 also reply original state, to carry out next
Secondary displacement equations.
In order to improve the amplification effect of lever construction further, lever arm 6 is Z-shape, is divided into outer by bending place ecto-entad
Section 6.1, stage casing 6.2 and inner segment 6.3.
Outer section of 6.1 tops are hinged with Triangular Arm 5, and inner segment 6.3 bottom is hinged with fulcrum bearing 7, reduce lever arm 6 arm of force
Length, enables lever arm 6 outer end greatly to move upwardly and inwardly, and increases the mobile range of Triangular Arm 5, improves vibration
Amplification effect.
In order to ensure lever triangle enlarger 4 stable motion, the length of the outer section of lever arm 6 is more than or equal to connecting rod 9
Length.Make actuating arm 8 be located at Triangular Arm 5 bottom part down, prevent actuating arm 8 motion from making to touch Triangular Arm 5, hinder Triangular Arm 5 to
Contract para-position moves and is amplified.
In order to mitigate abrasion, 3 bottoms of raising one's arm are parallel to be provided with cylindrical roller 10, the Triangular Arm 5 of lever triangle enlarger 4
Between by flexible hinge be connected, cylindrical roller 10 bottom position position is in flexible hinge.
Cylindrical roller 10 top is located in the mounting groove 11 of 3 bottom settings of raising one's arm, and mounting groove 11 inwall is and cylindrical roller
10 concentric circular arcs.
Lever triangle enlarger 4 promotes cylindrical roller 10, raises one's arm 3 by cylindrical roller 10 in promotion, cylindrical roller 10 with
Lever triangle enlarger 4 and the contact raised one's arm between 3 are all face contact, it is to avoid the abrasion that point contacts or linear contact lay causes, and damage
Lose displacement enlargement.
In order to piezoelectric stack 2 deforms maximum generation vertical displacement, spacing block 12, spacing block are installed in the pump housing 1
12 tops arrange the gathering sill 13 of opening upwards, and piezoelectric stack 2 is located in gathering sill 13.
Gathering sill 13 limits the direction of displacement that piezoelectric stack 2 deformation produces, and makes the vertical displacement that piezoelectric stack 2 produces maximum
The displacement amplitude increase passing to actuating arm 8, making that actuating arm 8 produces of degree, 3 Oscillation Amplitude thus enhancing is raised one's arm.
In order to improve the speed of service of all parts further, fixed seat 14 is installed in the pump housing 1, fixed seat 14 top is pacified
The fixed plate 15 of dress with raise one's arm that 3 rear ends are hinged, pin joint adopts flexible hinge.Raise one's arm 3 be swung up after, flexible hinge can be by
Raise one's arm 3 pullings playback, and the 3 promotion lever triangle enlargers 4 that make to raise one's arm playback, and increase the playback speed of all parts, make down
Athletic performance can be carried out faster, thus strengthening the frequency of vibration, improves pumpability.
