Abstract
The utility model patent provides a kind of ultrasonic bubble detector for being suitable for hard infusion pipeline.The hard tube ultrasonic bubble detector includes probing shell, probe support frame, transmitting transducer, reception energy converter, control circuit board and lead, probing shell and is fixed on outside probe support frame.The probing shell is flexible material, and probe support frame is hard material, and there is the snak link of protrusion at probe support frame both ends, has corresponding snak link groove respectively in probing shell, probing shell is closely connected with probe support frame by snak link respectively.It since the shell of detection is flexible material, can deform when being in close contact hard infusion pipeline, so as to fulfill fitting closely for detector and pipeline, any hard woven hose can be detected, and without additional couplant, direct drying measure to a certain degree.
Description
Technical field
The utility model is related to a kind of sensing device for detecting pipeline bubble within fluid, liquid in particularly a kind of hard pipeline
The sensing device of bubble, belongs to sensor field in body.
Background technology
In numerous liquid transportation arts, such as it is infusion pump in medical application, dialysis machine, printing, filling, in infusion pipeline
Bubble has stringent control, does not allow occur bubble in a liquid, so the bubble detection device in woven hose is of great significance.
And optical detector is difficult that nontransparent pipeline or nontransparent liquid are detected, ultrasonic wave does not have the translucency of medium any
It is required that so the gas bubble detection of ultrasonic wave mode is widely used.But ultrasonic detector is for the knot of medium and detector
It is stringent to close compactness requirement, and then the material of infusion pipeline is had certain limitations.Existing detection pipeline bubble within fluid surpasses
Acoustic detector, it usually needs woven hose is deformable soft materials, such as silica gel, rubber, flexible plastic, for being difficult deformation
Or rigid hard woven hose, such as polytetrafluoro, PEEK, PFA, metal or glass, then it can not measure or need to add couplant
Material can just be detected.Larger limitation is received in the application field being corrosive or the liquid of high temperature conveys.
Utility model content
(1) technical problems to be solved
Technical problems to be solved are to carry out bubble detection to hard infusion pipeline, without the use of any additional couplant.
(2) technical solution
In order to overcome above-mentioned technical problem, the utility model patent provides a kind of ultrasonic wave for being suitable for hard infusion pipeline
Gas bubble detection.The hard tube ultrasonic bubble detector is changed including probing shell, probe support frame, transmitting transducer, reception
Energy device, control circuit board and lead, probing shell are fixed on outside probe support frame.The probing shell is flexible material, is visited
Head support is hard material, and there is the snak link of protrusion at probe support frame both ends, has corresponding bullet respectively in probing shell respectively
Spring button groove, probing shell are closely connected with probe support frame by snak link.
The probing shell top is provided with a groove, and it is outer that transmitting transducer and reception energy converter are respectively symmetrically bonded in probe
On the outer wall of shell groove both sides.The width of groove is between 1mm to 30mm.The control circuit board is placed on the convex of pedestal,
One entirety is packaged by encapsulating.
It is closely embedded in the groove of detector to be tested infusion pipeline during work, since the shell of detection is flexible material, tightly
Contiguity can deform to a certain degree when touching hard infusion pipeline, so as to fulfill fitting closely for detector and pipeline so that ultrasonic wave
Signal, which is able to pass through pipeline, to be entered in fluid to be measured.Be detected in infusion pipeline liquid by when, if any bubble in liquid,
Then ultrasonic wave receives bubble obstruction and can not propagate, so as to fulfill perception.Hard tube ultrasonic bubble is visited described in entire detection process
Device is surveyed not contact with detected liquid.
(3) advantageous effect
The utility model solves the problems, such as that ultrasonic bubble detector can not detect hard woven hose, can be to any hard
Woven hose is detected, and without additional couplant, direct drying measure.
Description of the drawings：
Fig. 1 is the 3D entity schematic diagrames of the hard tube ultrasonic bubble detector of the utility model；
Fig. 2 is the 3D sectional views of the hard tube ultrasonic bubble detector of the utility model；
Specific embodiment：
As depicted in figs. 1 and 2, the utility model discloses a kind of hard tube ultrasonic bubble detectors, outer including popping one's head in
Shell 1, transmitting transducer 2, transmitting transducer line 3, probe support frame 4, control circuit board 5, packaging plastic 6, ground wire 7, supply lines
8th, signal output line 9, receive energy converter line 10 and receive energy converter 11,1 top of probing shell is provided with a groove 12, in groove
There is high molecular material pipeline 13 to pass through, to be detected liquid 14 in pipeline.
Probing shell 1 is rubber material, and probe support frame 4 is duroplasts, and probe support frame 4 and probing shell 1 pass through bullet
Spring button 4a interlocks with snak link groove 1a and is connect.It is recessed that transmitting transducer 2 and reception energy converter 11 are symmetrically adhesive in probing shell
12 both sides outer wall of slot.2 tow sides of transmitting transducer draw one group of totally two transmitting transducer line 3, and with control circuit board 5
It is connected, receiving one group of 11 tow sides of energy converter extraction, totally two transmitting transducer lines 10 are also connected with control circuit board 5.Control
Circuit board 5 processed is placed on the convex 4b of probe support frame 4, and an entirety is packaged by encapsulating, the ground wire 7 of control circuit board 5,
Supply lines 8 and signal output line 9 are pierced by from packaging plastic 6.In 1 crown center of probing shell there are one groove 12, in groove 12
It is embedded to be tested infusion pipeline 13, there is detected liquid 14 to pass through in infusion pipeline 13, be detected between liquid 14 and probing shell 1
It is isolated by the infusion pipeline 13.Detector is not contacted with detected liquid in entire detection process.
