Description

Technical Field

[0001] This invention relates to thermometers, and more specifically, to a device and method for detecting the flow rate at a thermometer drip point. Background Technology

[0002] A point is set at the bulb of the thermometer. When measuring body temperature, the liquid inside the bulb is heated, rises through the constriction, and stabilizes before the temperature is read. When reading the temperature, the liquid breaks off at the constriction, and the liquid column above maintains a constant reading.

[0003] The tightness of the processing point is particularly important during the processing. After the shrunken opening is finished, it is necessary to check the tightness of the processing point. If it is too loose, it will easily flow out by itself, and if it is too tight, it will be difficult to shake back the liquid bubble.

[0004] In the current production process, manual inspection is required. However, because the thermometer has a glass shell with a smooth surface that reflects light, and the spot is inside the glass shell with a very small diameter, manual inspection is labor-intensive and has poor accuracy. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device for detecting the flow rate at the throat of a thermometer. This device is used to detect the flow rate at the thermometer inlet, and has the advantages of intuitive and reliable detection results and high accuracy. The detection method is simple to operate.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical means:

[0007] A device for detecting the flow rate at a thermometer infusion point includes a tube frame and a U-shaped tube mounted on the tube frame, wherein the tube frame is hinged to a measuring support.

[0008] The U-shaped tube is a transparent tube containing a test liquid. The left and right sides of the U-shaped tube are the left and right sides, respectively. The height of the left side of the U-shaped tube is less than the height of the right side of the U-shaped tube. The part of the right side of the U-shaped tube that is higher than the left side of the U-shaped tube is the overflow prevention part of the U-shaped tube.

[0009] The top of the left side of the U-shaped tube is a detection tube, and a first fiber optic sensor and a second fiber optic sensor are arranged at intervals above the detection tube; the positions of the detection tube corresponding to the detection heads of the first fiber optic sensor and the second fiber optic sensor are the first measurement point and the second measurement point, respectively; the right side port of the detection tube is connected to one end of the test connection hose, and the other end of the test connection hose is used to connect to the capillary tube at the test point.

[0010] The first fiber optic sensor and the second fiber optic sensor are electrically connected to the host and the display, respectively. The host and the display are used to receive, process and display data information, and the host and the display supply power to the first fiber optic sensor and the second fiber optic sensor.

[0011] The described pipe support is provided with a limiting component, and the limiting component defines the amplitude of rotation of the pipe support.

[0012] The working principle of this device:

[0013] After the connection is set up, rotate the pipe support to make the left side of the pipe support lower and the right side higher. When the detection liquid contained in the U-shaped pipe passes through the first measurement point, the first fiber optic sensor transmits a signal to the host and the display. When the detection liquid passes through the second measurement point, the second fiber optic sensor transmits a signal to the host and the display; the host and the display calculate the detection time difference between the detection liquid passing through the first measurement point and the second measurement point based on the received signals, and the display screen shows the detection time difference; the host and the display compare the displayed time difference with the standard time difference data of qualified products. If the detection time difference is within the range of the standard time difference data, the detection is qualified; if the detection time difference is less than the minimum value of the standard time difference data or greater than the maximum value of the standard time difference data, the detection is unqualified; the detection result is displayed through the display screen.

[0014] For the detection of this device, only gas passes through the capillary under test during the detection, maintaining its cleanliness; during the detection process, the detection time difference of the detection liquid passing through the first measurement point and the second measurement point is compared with the standard time difference data of qualified products; thus, a conclusion of qualified or unqualified can be obtained intuitively and accurately. It should be noted that the standard time difference is a data range (data interval) measured for qualified products. This device is used to detect the flow rate at the constriction of the thermometer, and has the advantages of intuitive and reliable detection results and high precision; this detection method has simple operation steps.

[0015] The further preferred technical solutions are as follows:

[0016] The described pipe support is a rectangular frame, and a vertically arranged support frame is provided in the middle; the pipe support is hinged to the measurement pillar through the support frame.

[0017] By setting the support frame, firstly, the strength of the pipe support is increased, and secondly, it is convenient to connect the measurement pillar using the support frame.

[0018] The side of the described pipe support is provided with a U-shaped pipe embedding groove and a sensor embedding groove. The U-shaped pipe is a glass pipe and is arranged in the U-shaped pipe embedding groove.

[0019] The described measurement pillar is connected and arranged on the measurement pedestal, and a display pillar is also provided on the measurement pedestal. The host and the display are connected and arranged on the display pillar.

[0020] By setting the measurement pedestal and the display pillar, it is convenient for the connection and arrangement of the host and the display and the observation of the displayed data.

[0021] The described limiting component is a left limiting column and a right limiting column arranged on both sides of the measurement pillar, and the height of the right limiting column is greater than the height of the left limiting column.

[0022] The inclusion of left and right limit posts facilitates the control of the pipe rack's rotation. The right limit post is taller than the left limit post to prevent the detection liquid from overflowing.

[0023] The left and right limiting posts are respectively provided with a left elastic pad and a right elastic pad.

[0024] By setting left and right elastic pads, the contact between the pipe rack and the left and right limit posts is made gentle.

[0025] The tube rack has a sensor rail platform parallel to the detection tube above it. The sensor rail platform has a first sensor seat and a second sensor seat whose positions can be adjusted by sliding along its surface. The first sensor seat and the second sensor seat are respectively connected to a first fiber optic sensor and a second fiber optic sensor.

[0026] By setting up a sensor rail, a first sensor base, and a second sensor base, the spacing between the first and second sensor bases can be easily adjusted to meet the detection needs of thermometers of different specifications and models.

[0027] The measuring platform is equipped with a connecting beam frame, which has spaced-apart connecting holes for connecting measuring supports and display supports. The connecting beam frame increases the stability of the measuring platform, and the connecting holes facilitate the connection and installation of measuring supports and display supports.

[0028] A method for detecting the flow rate at the constriction of a thermometer using a device includes the following steps:

[0029] (a) Rotate the tube rack of this measuring device to a horizontal position;

[0030] (b) Turn on the host and display. The host and display will power the first sensor base and the second sensor base to prepare for measurement.

[0031] (c) Connect one end of the constricted capillary to be tested to the end of the test connection hose;

[0032] (d) Rotate the tube rack so that the left side is lower than the right side. When the test liquid in the U-shaped tube passes through the first measurement point, the first fiber optic sensor transmits a signal to the host and the display. When the test liquid passes through the second measurement point, the second fiber optic sensor transmits a signal to the host and the display. The host and the display calculate the detection time difference between the first measurement point and the second measurement point based on the received signals, and the display shows the detection time difference.

[0033] (e) The host and monitor compare the time difference displayed with the standard time difference of qualified products. If the detection time difference is within the range of the standard time difference, the test is qualified; if the detection time difference is less than the minimum value of the standard time difference or greater than the maximum value of the standard time difference, the test is unqualified. The test results are displayed on the screen. Attached Figure Description

Detailed Implementation

[0038] The present invention will be further described below with reference to the embodiments.

[0039] See Figure 1 , 2 As can be seen from 3, the device for detecting the flow rate of a thermometer drip point according to the present invention consists of a tube frame 2 and a U-shaped tube 4 set on the tube frame.

[0040] The U-shaped tube 4 is a transparent tube, and the U-shaped tube 4 contains the detection liquid. The left and right sides of the U-shaped tube 4 are the left side tube 1 and the right side tube 12, respectively. The height of the left side tube 1 is less than the height of the right side tube 12. The part of the right side tube 12 that is higher than the left side tube 1 is the overflow prevention part 22 of the U-shaped tube.

[0041] The top end of the left tube 1 of the U-shaped tube is a detection tube, and a first fiber optic sensor 17 and a second fiber optic sensor 15 are arranged at intervals above the detection tube; the positions of the detection tube corresponding to the detection heads of the first fiber optic sensor 17 and the second fiber optic sensor 15 are the first measurement point 18 and the second measurement point 13, respectively; the right port of the detection tube is connected to one end of the test connection hose 11, and the other end of the test connection hose 11 is used to connect to the throat capillary to be tested.

[0042] The first fiber optic sensor 17 and the second fiber optic sensor 15 are electrically connected to the host and the display 20, respectively. The host and the display 20 are used to receive, process, and display data information, and supply power to the first fiber optic sensor 17 and the second fiber optic sensor 15. The host and the display 20 are branded as Fuhuatong, model OP325-A; the first fiber optic sensor 17 and the second fiber optic sensor 15 are branded as F&C, model FF-403G.

[0043] The pipe rack 2 is equipped with a limiting component, which limits the range of rotation of the pipe rack 2.

[0044] The working principle of this device is as follows:

[0045] After the connection is set up, rotate the tube rack 2 so that the left side is lower than the right side. When the test liquid in the U-shaped tube 4 passes through the first measuring point 18, the first fiber optic sensor 17 transmits a signal to the host and display 20. When the test liquid passes through the second measuring point 13, the second fiber optic sensor 15 transmits a signal to the host and display 20. The host and display 20 calculate the detection time difference between the first measuring point 18 and the second measuring point 13 based on the received signals, and the display shows the detection time difference. The host and display 20 compare the displayed time difference with the standard time difference data of qualified products. If the detection time difference is within the data range of the standard time difference, the test is qualified. If the detection time difference is less than the minimum value of the standard time difference or greater than the maximum value of the standard time difference, the test is unqualified. The test result is displayed on the display screen.

[0046] This device detects that only gas passes through the constricted capillary tube being tested, maintaining its cleanliness. The testing process compares the time difference between the liquid passing through the first measuring point 18 and the second measuring point 13 with the standard time difference data of a qualified product, thus providing a direct and accurate conclusion on whether it is qualified or not. It should be noted that the standard time difference is a data range obtained from measurements of a qualified product. This device is used to detect the flow rate at the constriction of a thermometer, offering advantages such as intuitive and reliable results, high accuracy, and simple operation.

[0047] The tube frame 2 is a rectangular frame with a vertical support frame in the middle; the tube frame 2 is hinged to the measuring column 7 through the support frame.

[0048] By setting up a support frame, firstly, the strength of the pipe rack 2 is increased, and secondly, it is easier to connect the measuring support column 7 using the support frame.

[0049] The side of the tube frame 2 is provided with a U-shaped tube groove and a sensor groove. The U-shaped tube is a glass tube, and the U-shaped tube 4 is set in the U-shaped tube groove.

[0050] The measuring support 7 is connected to the measuring platform 8, and the measuring platform 8 is also provided with a display support 21. The host and display 20 are connected to the display support 21.

[0051] By setting up the measuring platform 8 and the display support 21, it is convenient to connect and set up the host and the display 20 and to observe the displayed data.

[0052] The limiting components are a left limiting post 6 and a right limiting post 9 set on both sides of the measuring support post 7, with the height of the right limiting post 9 being greater than the height of the left limiting post 7.

[0053] The left limiting post 6 and the right limiting post 9 are designed to limit the rotation of the pipe rack 2. The height of the right limiting post 9 is greater than the height of the left limiting post 7 to ensure that the detection liquid will not overflow.

[0054] The left limiting post 6 and the right limiting post 9 are respectively provided with a left elastic pad 5 and a right elastic pad 10.

[0055] By setting the left elastic pad 5 and the right elastic pad 10, the contact between the pipe rack 2 and the left limiting post 6 and the right limiting post 9 is made gentle.

[0056] The tube rack 2 is provided with a sensor rail 19 parallel to the detection tube above the detection tube. The sensor rail 19 is provided with a first sensor seat 16 and a second sensor seat 14 whose positions can be adjusted by sliding along its surface. The first sensor seat 16 and the second sensor seat 14 are respectively connected to a first fiber optic sensor 17 and a second fiber optic sensor 15.

[0057] By setting up the sensor rail 19, the first sensor seat 16, and the second sensor seat 14, the spacing between the first sensor seat 16 and the second sensor seat 14 can be easily adjusted to meet the detection needs of thermometers of different specifications and models.

[0058] The measuring platform 8 is equipped with a connecting beam frame, which has spaced connecting holes for connecting the measuring support column 7 and the display support column 21. The connecting beam frame increases the stability of the measuring platform 8, and the connecting holes facilitate the connection and installation of the measuring support column 7 and the display support column 21. Figure 3 As shown, the connecting beam frame is also equipped with two circular holes for connecting and setting the left limiting post 6 and the right limiting post 9.

[0059] See Figure 1 , Figure 2 It is known that a detection method for a device for detecting the flow rate at a thermometer infusion point includes the following steps:

[0060] (a) Rotate the tube frame 2 of this measuring device to a horizontal position;

[0061] (b) Turn on the host and display 20. The host and display 20 will supply power to the first sensor base 16 and the second sensor base 14 to prepare for measurement.

[0062] (c) Connect one end of the constricted capillary tube to be tested to the end of the test connection hose 11;

[0063] (d) Rotate the tube rack 2 so that the left side of the tube rack 2 is lower than the right side. When the detection liquid contained in the U-shaped tube 4 passes through the first measurement point 18, the first fiber optic sensor 17 transmits a signal to the host and display 20. When the detection liquid passes through the second measurement point 13, the second fiber optic sensor 15 transmits a signal to the host and display 20. The host and display 20 calculate the detection time difference between the detection liquid passing through the first measurement point 18 and the second measurement point 13 based on the received signals, and the display screen shows the detection time difference.

[0064] (e) The host and display 20 compare the time difference displayed with the standard time difference of the qualified product. If the detection time difference is within the range of the standard time difference, the detection is qualified; if the detection time difference is less than the minimum value of the standard time difference or greater than the maximum value of the standard time difference, the detection is unqualified; the detection result is displayed on the screen.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
