Abstract

The utility model belongs to a weighing appliance for experiments, which is a resonance weighting medicine spoon, and the front end of the resonance weighting medicine spoon is a common medicinal spoon (2). The utility model is characterized in that the common medicinal spoon (2) is fixedly arranged on the vibrating body (15) which can generate the resonance; the inside of the housing (1) of the vibrating body (15) is fixedly provided with a miniature motor (11); the axis of the miniature motor (11) is fixedly provided with an eccentric vibrating block (10); the miniature motor (11) is fixed on the inner wall of the housing (1) in the way that the spring (9) is squeezed by the attachments (4) of the movable and fixed pieces; the vibrating body (15) uses the miniature motor (11) to drive the vibrating block (10) to rotate to generate the resonance and pass to the medicinal spoon (2), which causes the medicinal powder in medicinal spoon (2) to generate vibration and to uniformly and continuously move outwards along the edge of the medicinal spoon (2) with a little amount. The utility model has the advantage of exact and rapid material feeding.

Description

Resonant mode weighing spoon

The utility model belongs to experiment weighing articles for use, is a kind of resonant mode weighing spoon.

For a long time, the experimenter realizes that with common spoon the trace of chemically examining medicine in the weighing process adds always, its method is in the weighing process, produce vibration by rapping spoon with finger, grasp the size and the speed of micro-addition by controlling the size of pointing the power of rapping, the size of rapping power because of finger is difficult to grasp, there is absorption affinity in various degree simultaneously between the various medicine particles, make add medicine particle size also be not quite similar, cause and often cause interpolation excessive, cause weighing repeatedly, influence the accuracy of weighing speed and weighing, especially strong to some hygroscopicity, the medicine influence of the quick weighing of the more high needs of temperature can be bigger.

The purpose of this utility model, provide a kind ofly can carry out quick and precisely, evenly trace, add the resonant mode weighing spoon of medicine continuously.

The purpose of this utility model is to realize by the resonance of spoon.The front end of resonant mode weighing spoon is a common spoon, its major technique feature is that common spoon is fixedly mounted on the vibrating body that can produce resonance, the enclosure of vibrating body fixedly mounts a micromachine, fixed installation one eccentric vibration block on the motor shaft, motor is fixed on the outer casing inner wall by the extruding of sound sheet attachment by spring, sound sheet attachment directly is adhesively fixed in the bayonet socket place and the shell of shell, moving plate attachment and still are bonded in respectively on the sound sheet attachment, vibrating body produces resonance and reaches spoon by shake piece rotation of driven by motor, make the medicinal powder in the spoon produce vibration and even along the edge of spoon, trace, outwards move continuously, have and add material accurately, advantage fast.

Resonance provided by the utility model is to be produced by the eccentric vibration block eccentric rotary that is fixed on the miniature electrical machinery axle, it is continuous to have the vibration that common spoon can't provide, the uniform characteristics of power value, continuity because of vibration, overcome with finger and rapped absorption affinity between the medicine particle that the common drug spoon can't overcome, make to add medicine particle even.Uniformity because of the vibration force size, the size of power when need not to consider again to rap the common drug spoon with finger, vibration force is provided by the eccentric rotary of eccentric vibration block, adding the size and the speed of amount of medicament can be controlled by the residing horizontality of spoon itself, very easy realization evenly trace is added, simultaneously, continuity because of vibration, can realize evenly trace interpolation continuously, the evenly micro-requirement of adding near adding purpose of one-time continuous also is easy to realize, unlikely often causing added excessively, causes repeatedly weighing repeatedly.

Fig. 1 is the structural representation according to the resonant mode weighing spoon that the utility model proposes.

Fig. 2 is the conspectus according to the resonant mode weighing spoon that the utility model proposes.

Its static structure:

The 1st, shell, the 2nd, common spoon, the 3rd, bayonet socket, the 4th, sound sheet attachment, the 5th, push switch, the 6th, moving plate attachment, the 7th, moving plate, the 8th, still, the 9th, spring, the 10th, the piece that shakes, the 11st, motor, the 12nd, electrode, the 13rd, power connection, the 14th, nut, the 15th, vibrating body

Its operation principle and method of operating are as follows, go up socket power at power connection (13), pressing push switch (5) connects circuit, motor (11) drives piece (10) rotation of shaking and produces vibration, vibration reaches common drug (2) by shell (1) and annex etc., make medicine on the common spoon (2) produce vibration and evenly, outwards move continuously, and change the size and the speed of common spoon (2) interpolation amount of medicament by the horizontality that changes common spoon (2) along the bezel of common spoon (2).

With press button (5) moving plate (7) still (8) cancellation, change the line resistance switch of slidingtype into, then can be by regulating the size of current in the motor (11), change the size frequently of shaking, to realize to adding the control of amount of medicament and speed.

Claims
