The housing 13 of syringe.
Control circuit board 3 is arranged in the inside of control panel 11, and 4 are connect with motor module.There are one being set on rear chassis 2
Battery insertion groove 21, a battery 22 is arranged in the battery insertion groove 21, and connects motor module 4 and control circuit board 3.This hair
Bright dosing electronic pump can normally make by external AC power or using built-in rechargeable battery 22 to stablize offer equipment
With the required energy.22 small volume of battery influences equipment overall weight little.Control panel as shown in FIG. 6, passes through
It presses the power knob on control panel 11 and opens equipment, and external 220V AC powers are confirmed by the indicator light on panel
Or charging is completed in equipment internal battery, can be used after confirmation.When use long-press " manual " is carried out according to actual demand
Button carries out liquid transfer, and the button that can also press " 60mL ", " 100mL ", " 200mL " or " 300mL " carries out quantitative transfer.
Geometrical clamp 5 there are one being set on rear chassis 2.
Referring to Fig. 2, motor module 4 is arranged in dosing electronics pump case, motor module 4 includes motor 41, sliding tooth
Wheel group 42, screw rod 43, guide rod 44, sliding stand 45, slide push rod 46.Drive gear set 42 includes driving gear 421, screw rod tooth
Wheel 422, photoelectric coded disk 423 and photoelectric coding circuit board 424.
Driving gear 421 is connect with motor 41, and is engaged with screw gear 422.The diameter of screw gear 422 is less than driving
The diameter of gear 421.Screw gear 422 is connect with screw rod 43.Since this product is shifted for liquid, screw rod quick rotation is needed
Achieve the purpose that accelerate slide push rod movement, it is when design gear group, standard compliant being checked to the strength of gear teeth and its torque
Under the premise of, it devises level-one and drives up, 41 input speed of motor is made to reach larger when driving to screw rod 43 and exporting rotating speed
Transmission ratio.
Photoelectric coded disk 423 is connect with motor 41, and connects photoelectric coded disk circuit board 424.Photoelectric coded disk 423 with
When motor 41 with rotational speed, is recorded by photoelectric coding circuit board 424 and control 41 turnning circle of motor, and it is fed back
To control circuit board 3, when turnning circle reaches program setting and sets value, motor stalling, the transfer of liquid also stops therewith.
Guide rod 44 is arranged in parallel with screw rod 43；Sliding stand 45 is socketed on screw rod 43 and guide rod 44, slide push rod 46
It is connect with sliding stand.As shown in figure 3, the top of slide push rod 46 connects a pressure sensor 461；461 He of pressure sensor
Pressure sensor circuit plate 462 connects.
One group of photoswitch circuit plate 47 is additionally provided on motor module 4.
As shown in figure 4, the dosing electronic pump of the present invention is before use, need 100mL disposable syringes fixing it
On.Syringe core rod tail end is caught in the groove of slide push rod first and completes to fix, syringe jacket 13 is then passed through into note
Emitter housing pressure handle 12 is locked.After fixing syringe, equipment is placed on smooth desktop or is fixed on by geometrical clamp 5
On metal pipe frame.
It, can be in such a way that positioning pin is inserted into the card slot of different stalls when needing equipment being fixed on pipe support
The position of relative level, relative level after fixing can be in when equipment being allowed to be fixed on the pipe support of differing tilt angles
12.5 ° of desired inclination angle=.
As shown in figure 5, connecting infusion pipeline after fixed, and check whether syringe is connect with external pipeline close.
So far, step is fixedly mounted to terminate.
When proceeding by dosing, corresponding button on control panel 11 is pressed, the motor 41 in motor module 4 starts to turn
Dynamic, the at the same time rotation of motor 41 has driven driving gear 421 to be rotated with photoelectric coded disk 423.By drive gear 421 with
Transmission between screw gear 422, screw rod 43 also rotate therewith.Sliding stand 45 due to screw rod 422 rotation, along guide rod 44
Direction moved flat, at the same time, the slide push rod 46 being fixed on sliding stand is also left therewith with syringe core rod
The right side moves flat.In photoelectric coded disk 423 with motor 41 with rotational speed when, by photoelectric coding circuit board 424 record simultaneously
41 turnning circle of motor is controlled, and it is fed back into control circuit board 3, when turnning circle reaches program setting and sets value, motor
41 stallings, the transfer of liquid also stop therewith.It, can also be by pressing control panel when liquid transfer amount does not reach setting value
" stopping " button on 3 allows motor stalls manually.
Dosing electronics pump operation to midway suddenly power-off or battery capacity is too low be automatically closed when, connect with the mains and open again
Equipment is opened, 41 automatic operating of motor can be allowed by 47 pre-set programs of photoswitch circuit plate and photoelectric sensor positioning thereon
Until sliding stand 45 is made to reset.It can ensure in this way when occurring the case where accident power-off, reclose piston after power supply
Bar can be returned to initial position again.Meanwhile the presence of photoswitch circuit plate 47 is also ensured when equipment breaks down and slides
Dynamic platform 45 move flat be not in overtravel situation.
Go out when device control panel breaks down, when can be to avoid equipment fault except through photoswitch circuit plate 47
Outside existing overtravel, it can also be passed through when the fortuitous events such as pipeline blockage, operation error cause slide push rod 46 to be overloaded
Interior 461 feedback signal of pressure sensor is to pressure sensor circuit plate 462, then controls motor 41 by control circuit board 3 and stall.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
