Detailed description of the invention
In order to enable preferably technical scheme to be understood, below by specifically embodiment
And combine accompanying drawing and be described in detail:
Refer to Fig. 1, a kind of dosing electronic pump of the present invention, including front cover 1, rear chassis 2,
Control circuit plate 3 and motor module 4.
Front cover 1 and rear chassis 2 are combined into the shell of dosing electronic pump.Front cover upper
Portion is provided with control panel 11, and bottom is provided with the syringe jacket pressure handle 12 of a upper hook-type.Syringe
Overcoat pressure handle 12 is in order to clamp the overcoat 13 of disposable 100ml syringe.
Control circuit plate 3 is arranged on the inner side of control panel 11, is connected 4 with motor module.After casing
Lid 2 is provided with a battery insertion groove 21, and a battery 22 is arranged in described battery insertion groove 21, and
Connect motor module 4 and control circuit plate 3.The dosing electronic pump of the present invention can be by external exchange
Power supply or use built-in rechargeable battery 22 stably provide equipment normally to use the required energy.
Battery 22 small volume, little on the impact of equipment overall weight.Control panel as shown in Figure 6,
Equipment is opened by pressing the power knob on control panel 11, and true by the indicator lamp on panel
Recognize the most external 220V AC power or equipment internal battery has completed charging, can make after confirmation
With.Carry out growing according to actual demand during use and press " manually " button and carry out liquid transfer, it is also possible to press
Under the button of " 60mL ", " 100mL ", " 200mL " or " 300mL " quantitatively shift.
Rear chassis 2 is provided with a geometrical clamp 5.
Referring to Fig. 2, motor module 4 is arranged in dosing electronic pump shell, and motor module 4 includes
Motor 41, drive gear set 42, screw rod 43, guide post 44, sliding stand 45, pusher 46.
Drive gear set 42 includes driving gear 421, screw gear 422, photoelectric coded disk 423 and photoelectricity
Coding circuit plate 424.
Drive gear 421 to be connected with motor 41, and engage with screw gear 422.Screw gear 422
Diameter less than drive gear 421 diameter.Screw gear 422 is connected with screw rod 43.Due to this
Product shifts for liquid, needs screw rod quick rotation to reach to accelerate the purpose of pusher motion,
During design gear group, the strength of gear teeth and moment of torsion thereof are being checked under standard compliant premise, is devising one
Level drives up, and makes motor 41 input speed reach bigger when driving to screw rod 43 output speed
Gearratio.
Photoelectric coded disk 423 is connected with motor 41, and connects photoelectric coded disk circuit board 424.At light
Electricity coding disk 423 along with motor 41 with rotational speed time, by photoelectric coding circuit board 424 record
And control motor 41 and rotate the number of turns, and it is fed back to control circuit plate 3, count to reach journey at turning collar
Sequence sets when putting value, and motor stalling, the transfer of liquid stops the most therewith.
Guide post 44 be arranged in parallel with screw rod 43；Sliding stand 45 is socketed in screw rod 43 and guide post 44
On, pusher 46 is connected with sliding stand.As it is shown on figure 3, the top of pusher 46 connects one
Individual pressure sensor 461；Pressure sensor 461 and pressure sensor circuit plate 462 connect.
One group of photoswitch circuit plate 47 it is additionally provided with on motor module 4.
As shown in Figure 4, before the dosing electronic pump of the present invention uses, need 100mL single use
Syringe is fixed thereon.First complete solid in syringe core rod tail end is snapped in the groove of pusher
Fixed, then syringe jacket 13 is carried out locked by syringe jacket pressure handle 12.Fix injection
After device, equipment is placed on smooth desktop or is fixed on metal pipe frame by geometrical clamp 5.
When equipment is fixed on pipe support by needs, by alignment pin being inserted the draw-in groove of different gear
Mode, all can be in the position of relative level when equipment can be allowed to be fixed on the pipe support of differing tilt angles
Put, the desired inclination angle=12.5 ° of relative level after it is fixing.
As it is shown in figure 5, connect infusion pipeline after Gu Ding, and check that syringe is with external pipeline even
Connect the tightst.So far, fixed installation step terminates.
When proceeding by dosing, press button corresponding on control panel 11, in motor module 4
Motor 41 start rotate, the meanwhile rotation of motor 41 has driven driving gear 421 and photoelectricity
Coding disk 423 rotates.By driving the transmission between gear 421 and screw gear 422, screw rod 43
Also concomitant rotation.Sliding stand 45, due to the rotation of screw rod 422, is carried out along the direction of guide post 44
Moving flat, meanwhile, the pusher 46 being fixed on sliding stand is also with syringe core rod
Left and right moves flat therewith.Photoelectric coded disk 423 along with motor 41 with rotational speed time, pass through
Photoelectric coding circuit board 424 records and controls motor 41 and rotates the number of turns, and it feeds back to control electricity
Road plate 3, turning collar count to reach program setting put value time, motor 41 stall, the transfer of liquid also with
Stopping.When liquid transfer amount does not arrives setting value, it is also possible to by pressing on control panel 3
" stop " button and manually allow motor stalls.
Dosing electronic pump run to midway suddenly power-off or battery electric quantity is too low be automatically switched off time, connect
Power supply is again turned on equipment, by photoswitch circuit plate 47 pre-set programs and photoelectric sensing thereon
Device location can allow motor 41 automatically operate until making sliding stand 45 reset.So can ensure that and take notice of
When the situation of outer power-off occurs, after reclosing power supply, syringe core rod can be returned to initial bit again
Put.Meanwhile, the existence of photoswitch circuit plate 47 also ensures that sliding stand when equipment breaks down
45 move flat the situation not havinging stroke.
When device control panel breaks down, except being avoided by photoswitch circuit plate 47
Occurred during equipment fault outside stroke, it is also possible to occur at the fortuitous event such as pipeline blockage, operational error
When causing pusher 46 to be transshipped, feed back signal to pressure by its interior pressure sensor 461 and pass
Sensor circuit board 462, then controlled motor 41 stall by control circuit plate 3.
Those of ordinary skill in the art is it should be appreciated that above embodiment is intended merely to
The bright present invention, and it is not used as limitation of the invention, as long as at the spirit of the present invention
In, change, the modification of embodiment described above all will be fallen in the range of claims of the present invention.
