Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, a kind of embodiment provided by the invention：A kind of transfusion drip tube of automatic adjustment flow velocity, including drop
Tube body 1 is provided with interlayer 11 in dropper ontology 1, and dropper ontology is divided into two cavitys up and down by interlayer 11, and upper cavity is to deposit
Sap cavity 12, lower chamber are adjusting cavity 13, and 12 upper end of liquid storage chamber is provided with liquid entrance 21, liquid entrance 21 and 12 phase of liquid storage chamber
Logical, 13 bottom end of adjusting cavity is provided with medicine liquid outlet 23.
Further, liquid level sensor 1 and liquid level sensor 2 32, liquid level sensor 1 are provided in liquid storage chamber 12
It is arranged on 2 32 top of liquid level sensor.
Further, it is provided with regulation pipe 22 in adjusting cavity 13 and adjusts cam 33, in the adjusting cavity 13 in 22 left side of regulation pipe
Supporting rack 14 is provided on wall, supporting rack 14 is contacted with regulation pipe 22, and through-hole is provided on interlayer 11, and 22 upper end of regulation pipe passes through
Through-hole on interlayer 11 is connected with liquid storage chamber 12, and 22 lower end of regulation pipe is connected with medicine liquid outlet 23, and 22 right side of regulation pipe is set
It is equipped with and adjusts cam 33, adjust 33 input terminal of cam and be provided with micromotor 34, adjust 33 lower section of cam and be provided with micro machine control
Device 35 and minicell 36 processed, minicell 36 are electrically connected with micro machine controller 35, micromotor 34 and level sensing
Device 1 and liquid level sensor 2 32 are all electrically connected with micro machine controller 35.
Preferably, dropper ontology 1 is cylindrical cavity.
Preferably, 22 internal diameter of regulation pipe is identical as the internal diameter of liquid entrance 21 and medicine liquid outlet 23.
Preferably, the volume of liquid storage chamber 12 is less than the volume of adjusting cavity 13.
Preferably, regulation pipe 22 is PVC hose.
Operation principle：When using the transfusion drip tube of the automatic adjustment flow velocity, by the liquid entrance 21 and medicine of dropper ontology 1
Liquid outlet 23 is connected with woven hose respectively, opens micro machine controller 35, and micro machine controller 35 is by minicell 36
Micromotor 34 and the power supply of liquid level sensor 1 and liquid level sensor 2 32, and receive liquid level sensor 1 and liquid level biography
The electric signal of sensor 2 32 controls the action of micromotor 34 by signal processing.When liquid position is higher than liquid level sensor one
When 31 position, indicate that liquid is also sufficient, it is not necessary to which limited flow rate, liquid level sensor 1 and liquid level sensor 2 32 are given simultaneously at this time
Micro machine controller 35 sends signal, and micro machine controller 35 controls micromotor 34 and is failure to actuate, that is, adjusts cam 33 and be in Fig. 1
Position；When liquid position is less than liquid level sensor 1 and is higher than liquid level sensor 2 32, indicates that liquid is inadequate, need
Limited flow rate is wanted, liquid level sensor 1 does not signal at this time, and liquid level sensor 2 32 signals, and micro machine controller 35 controls
