Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a bubble detection device. Background Technology

[0002] A bubble detection device can be used to detect the presence of bubbles in liquid passing through a tube, and it can be applied in fields such as beverage machines and medical reagent infusions. For example, Chinese Patent Publication No. CN214318773U discloses a bubble detection device for an infusion tube, comprising: a U-shaped housing, including a first arm housing and a second arm housing with a gap between them, the first arm housing having a first slit and the second arm housing having a second slit, the first slit and the second slit being opposite each other; a light-emitting device disposed within the first arm housing, with its light-emitting end opposite to the first slit; a light-receiving device disposed within the second arm housing, with its photosensitive end opposite to the second slit; a signal processing module disposed within the housing, with its input end connected to the light-receiving device; and an alarm module connected to the output end of the signal processing module.

[0003] When the existing bubble detection device detects bubbles in the infusion tube, the infusion tube is placed in the gap between the first and second support arm housings, the light-emitting devices are located on opposite sides of the infusion tube, and there is a detection blind zone at the bottom of the infusion tube.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] The purpose of this invention is to provide a bubble detection device to address the shortcomings and deficiencies of existing technologies.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a bubble detection device, including a detection tube disposed on a liquid pipeline, a first sensor and a second sensor. The first sensor includes a first transmitting element and a first receiving element, and the second sensor includes a second transmitting element and a second receiving element.

[0008] The detection tube has a channel running through its front and rear ends, and the outer wall of the detection tube includes an upper side wall and a lower side wall that are opposite to each other, and a left side wall and a right side wall that are opposite to each other.

[0009] One of the first transmitting element and the first receiving element is disposed on the upper sidewall, and the other is disposed on the lower sidewall;

[0010] One of the second transmitting element and the second receiving element is disposed on the left side wall, and the other is disposed on the right side wall;

[0011] The detection areas of the first and second sensors cover the cross-section of the channel.

[0012] With the above structural arrangement, the first sensor and the second sensor are cross-distributed on different side walls of the detection tube, thereby detecting bubbles in the liquid in the channel from two different directions. This ensures that the detection areas of the first sensor and the second sensor cover the cross-section of the channel, effectively avoiding detection blind spots.

[0013] According to the above scheme, the detection tube is provided with a first mounting base and a second mounting base. The first mounting base is provided with mounting slots for mounting the first transmitting element and the first receiving element, respectively; the second mounting base is provided with mounting slots for mounting the second transmitting element and the second receiving element, respectively.

[0014] With the above structural arrangement, the first sensor and the second sensor are mounted on the outer wall of the detection tube.

[0015] According to the above scheme, the first mounting base and the second mounting base are integrally formed with the detection tube. This structural design simplifies the overall structure.

[0016] According to the above scheme, the length of the first transmitting element perpendicular to the channel axis is not less than the diameter of the channel, and the size of the first receiving element is the same as that of the first transmitting element; the length of the second transmitting element perpendicular to the channel axis is not less than the diameter of the channel, and the size of the second receiving element is the same as that of the second transmitting element. Through this structural arrangement, the detection areas of the first and second sensors respectively cover the cross-section of the channel, further avoiding the problem of detection blind spots.

[0017] According to the above scheme, it also includes an inlet pipe and an outlet pipe, wherein the inlet pipe is connected to the front end of the channel and the outlet pipe is connected to the rear end of the channel.

[0018] According to the above scheme, a signal processing module is also included, which is connected to the first transmitting element, the first receiving element, the second transmitting element, and the second receiving element respectively.

[0019] The first receiving element and the second receiving element respectively send the detection feedback signal to the signal processing module. The signal processing module processes the detection feedback signal to determine whether there are air bubbles in the liquid flowing through the channel.

[0020] It is understood that those skilled in the art can configure the signal processing module to perform operations such as liquid flow rate and actual bubble size estimation based on the detection feedback signal, in addition to determining the presence of bubbles, to meet the need for extensibility calculations and obtain more information.

[0021] According to the above scheme, it also includes a controller, which is connected to the signal processing module.

[0022] The controller sends a detection command to the signal processing module. Upon receiving the command, the signal processing module sends detection signals to the first and second transmitting elements, thus initiating the detection process. The controller can also be electrically connected to other devices (such as alarms) to control their operation based on the detection feedback signals.

[0023] According to the above scheme, the first sensor and the second sensor are ultrasonic sensors.

[0024] According to the above scheme, the first sensor and the second sensor are photoelectric sensors, and the detection tube is set as an optically transparent tube.

[0025] An optically transparent tube is a tube made of a highly transparent material that allows light emitted from the first emitting element and the second emitting element to illuminate the liquid inside the channel, and then be received by the first receiving element and the second receiving element, respectively.

[0026] It is understood that the working principle of the first and second sensors for detecting bubbles is existing technology, and will not be described in detail here.

[0027] According to the above scheme, the number of the first sensor is set to one or more; the number of the second sensor is set to one or more.

[0028] Understandably, the number of the first and second sensors can be set according to actual needs. When multiple sensors are set, they are arranged side by side along the channel axis. Judging the presence of air bubbles based on the detection results of multiple sensors helps to further improve detection accuracy.

[0029] The beneficial effects of this utility model are as follows:

[0030] This invention features a channel extending through the front and rear ends of a detection tube. One of a first transmitting element and a first receiving element is located on the upper side wall of the detection tube, and the other is located on the lower side wall. One of a second transmitting element and a second receiving element is located on the left side wall of the detection tube, and the other is located on the right side wall. This arrangement allows the first and second sensors to be distributed alternately on different side walls of the detection tube, enabling the detection of air bubbles in the liquid within the channel from two different directions. The detection areas of the first and second sensors cover the cross-section of the channel, effectively avoiding detection blind spots. Attached Figure Description

[0040] One of the second transmitting element 31 and the second receiving element 32 is disposed on the left side wall 14, and the other is disposed on the right side wall 15;

[0041] The combined detection area of ​​the first sensor 2 and the second sensor 3 covers the cross-section of the channel 11.

[0042] With the above structural arrangement, the first sensor 2 and the second sensor 3 are cross-distributed on different side walls of the detection tube 1, thereby detecting bubbles in the liquid in the channel 11 from two different directions. This ensures that the sum of the detection areas of the first sensor 2 and the second sensor 3 covers the cross-section of the channel 11, effectively avoiding the existence of detection blind spots.

[0043] Furthermore, the detection tube 1 is provided with a first mounting seat 16 and a second mounting seat 17. The first mounting seat 16 is provided with mounting slots 18 for mounting the first transmitting element 21 and the first receiving element 22, respectively. The second mounting seat 17 is provided with mounting slots 18 for mounting the second transmitting element 31 and the second receiving element 32, respectively.

[0044] Installation can be completed by installing the first transmitting unit, the first receiving element 22, the second transmitting element 31, and the second receiving element 32 into their respective mounting slots 18. Installation and disassembly are quick and easy.

[0045] Furthermore, the length of the first transmitting element 21 perpendicular to the axis of the channel 11 is not less than the diameter of the channel 11, and the size of the first receiving element 22 is the same as that of the first transmitting element 21; the length of the second transmitting element 31 perpendicular to the axis of the channel 11 is not less than the diameter of the channel 11, and the size of the second receiving element 32 is the same as that of the second transmitting element 31.

[0046] With the above structural arrangement, the detection areas of the first sensor 2 and the second sensor 3 respectively cover the cross-section of the channel 11, further avoiding the problem of detection blind spots.

[0047] Furthermore, it also includes an inlet pipe 4 and an outlet pipe 5, wherein the inlet pipe 4 is connected to the front end of the channel 11 and the outlet pipe 5 is connected to the rear end of the channel 11.

[0048] Furthermore, it also includes a signal processing module 6 and a controller 7.

[0049] Furthermore, the first sensor 2 and the second sensor 3 are ultrasonic sensors or photoelectric sensors; when the first sensor 2 and the second sensor 3 are photoelectric sensors, the detection tube 1 is set as an optically transparent tube.

After receiving the detection command, the signal processing module 6 sends a detection signal to the first transmitting element 21 and the second transmitting element 31, thereby starting the detection. The first receiving element 22 and the second receiving element 32 respectively send the detection feedback signal to the signal processing module 6. The signal processing module 6 processes the detection feedback signal to determine whether there are bubbles in the liquid flowing through the channel 11. After receiving the judgment result of the signal processing module 6 on whether there are bubbles, if the judgment result is that there are bubbles, the controller 7 controls the alarm 8 to work and issue an alarm.
