Description

Intelligent digital display suction gun Technical Field

[0001] This utility model relates to the field of suction gun technology, and in particular to an intelligent digital display suction gun. Background Technology

[0002] The intelligent digital display suction gun is an advanced tool that integrates modern electronic technology with the functions of a traditional suction gun. It is particularly suitable for scenarios that require precise measurement and monitoring of the gas intake process, such as in the field of helium mass spectrometry leak detector technology.

[0003] The existing traditional suction guns usually have their capillary tubes installed at the air inlet of the suction gun tube. In actual use, the capillary tubes are easily blocked, which affects the measurement results. At the same time, it is very inconvenient to disassemble, clean or replace the capillary tubes, making maintenance inconvenient and reducing practicality.

[0004] To address the aforementioned issues, this utility model document proposes an intelligent digital display suction gun. Summary of the Invention

[0005] This utility model provides an intelligent digital display suction gun, which solves the problems of existing technology. In traditional suction guns, the capillary tube is usually installed at the air inlet of the suction gun tube, which can easily cause the capillary tube to become blocked during actual use, thus affecting the measurement effect. At the same time, it is very inconvenient to disassemble, clean or replace the capillary tube, making maintenance inconvenient and reducing practicality.

[0006] This utility model provides the following technical solution:

[0007] Intelligent digital display suction gun, including:

[0008] A handle, one end of which is connected to a probe tube, and the end of the probe tube away from the handle is connected to a connector;

[0009] The end of the connector away from the probe pipe is detachably connected to a filter head, which is used to filter moisture, oil mist, and dust in the inhaled gas. The detachable end of the filter head away from the connector is connected to a suction gun head.

[0010] In one possible design, a KF connection plate is provided at the end of the handle away from the probe pipe. The KF connection plate is electrically connected to the handle via a communication line. The KF connection plate is provided with a communication line outlet for connecting to an external leak detector.

[0011] In one possible design, two wire fixing heads are provided between the KF connecting plate and the handle, and a resin tube is fixedly provided between the two wire fixing heads. The ends of the two wire fixing heads away from the resin tube are respectively connected and fixed to the handle and the KF connecting plate.

[0012] In one possible design, the handle is equipped with a display screen, which has two buttons.

[0013] In one possible design, a PCB board is fixedly mounted inside the handle. The PCB board is electrically connected to the display screen and is used to read the leak rate value of the leak detector and display the detected leak rate on the display screen in real time.

[0014] In one possible design, a flow-limiting conduit is provided inside the probe conduit, with one end of the flow-limiting conduit connected to a connector and the other end of the flow-limiting conduit away from the connector connected to a handle.

[0015] In this application, during use, the intelligent digital display suction gun first draws in the gas to be tested through the suction gun head. The suction gun head, as the gas inlet, takes into account the efficiency and stability of the gas intake to ensure the accuracy of the test results. The gas is first filtered through the filter head to remove impurities such as moisture, oil mist, and dust, ensuring the accuracy of subsequent tests and preventing blockage of the subsequent pipes. The filtered gas enters the probe pipe through the connector and continues to flow to the handle. Inside the probe pipe, the gas flow is limited by the flow-limiting pipe to control the amount of gas drawn in, ensuring that the working pressure of the leak detector is within the normal range, thus ensuring stable gas flow and accurate detection. At the same time, the filter head is connected to the connector through a detachable connection to facilitate disassembly, which is beneficial for cleaning or replacing the filter head after long-term use, improving convenience.

[0016] The gas ultimately enters the handle and then flows through the resin tube into the leak detector. The internal PCB board reads the leak rate value from the external leak detector and transmits this data in real-time to the display screen. The display screen shows the detected leak rate value in real time, allowing users to easily monitor the detection status. Buttons are used to operate the intelligent digital display suction gun, such as starting the detection and switching display modes. This eliminates the need for operators to operate the leak detector itself; they can operate directly from the suction gun handle, improving ease of use. The KF connecting plate is electrically connected to the handle via a communication cable, enabling data transmission and communication between the intelligent digital display suction gun and the external leak detector. The communication cable outlet is an interface on the KF connecting plate for connecting the external leak detector's communication cable, enhancing applicability. A wire fixing head secures the resin tube between the handle and the KF connecting plate, ensuring a stable connection and transmission of the wires. The resin tube also acts as a protective sleeve for the internal wires and pipes, preventing damage or interference during use and improving overall performance.

[0017] In this invention, the intelligent digital display suction gun, through the setting of filter head and connecting parts, can filter out impurities such as moisture, oil mist and dust in the gas to ensure the accuracy of subsequent detection, while avoiding blockage of the downstream pipeline. It can also limit the gas flow to control the amount of gas sucked in, ensuring that the working pressure of the leak detector is within the normal range, so as to ensure stable gas flow and detection accuracy.

[0018] In this utility model, the intelligent digital display suction gun, through the setting of PCB board, display screen and buttons, can read the leak rate value of external leak detector and transmit these data to the display screen in real time for display, so that users can understand the detection situation at any time. It is also convenient to operate the intelligent digital display suction gun, so that the operator does not need to operate on the leak detector body, thus improving the ease of use.

[0019] This invention can filter out impurities such as moisture, oil mist, and dust from the gas to ensure the accuracy of subsequent testing, while also preventing blockage of downstream pipelines. It also facilitates the disassembly of the filter head, making it easier to clean or replace filter heads that have been used for a long time, thus improving convenience. Attached Figure Description
