Abstract
Description
Technical Field
[0001] This invention relates to the field of microelectronics manufacturing technology, and more specifically to an oxygen transfer module shielding cover that is easy to install. Background Technology
[0002] An oxygen transfer module is a detection device primarily used to measure the concentration of oxygen gas in the environment. During operation, it generates interference and radiation. The higher the power of the oxygen transfer module, the greater the interference and radiation. The working environment of the oxygen transfer module contains many complex interference sources, such as external electric and magnetic fields. These sources affect the measurement accuracy and lifespan of the module. When measuring the oxygen concentration, the oxygen intake volume affects the measurement, and atmospheric pressure also affects the intake volume. Existing oxygen transfer modules suffer from problems such as electrolyte solution evaporation and leakage. These issues can easily prevent the module from reaching its expected lifespan and may even lead to combustion and other hazards. The metal casing on a wireless module is called a shielding cover, which is part of the module's hardware. While existing shielding covers isolate interference and radiation, they can affect the heat dissipation of internal components. Summary of the Invention
[0003] To address the aforementioned technical problems, this invention provides an easily installable oxygen transfer module shielding cover, including a filtering mechanism. The filtering mechanism includes a filter sleeve, with a filter screen fixedly connected to the inner wall of the filter sleeve. This filter screen increases the stability of the module's air inlet and also provides a certain degree of filtration, preventing impurities from entering and affecting operational stability. A ventilated membrane is fixedly connected to the inner wall of the filter sleeve. This filtering mechanism, being the module's only air inlet, provides filtration, ensuring measurement accuracy. The device also includes:
[0004] The shielding mechanism includes a left shielding shell, with several rectangular buckles on the side wall of the left shielding shell, and a right shielding shell that is snapped onto the side wall of the left shielding shell. The side wall of the right shielding shell has several rectangular slots, and the outer walls of the rectangular buckles engage with the inner walls of the rectangular slots. This shielding mechanism isolates the oxygen transfer module from interference and radiation. The connection method of the rectangular buckles and rectangular slots facilitates the installation of the shielding mechanism and makes it easy to disassemble and replace.
[0005] The electrode mechanism includes an electrode housing, an isolation frame fixedly connected to the inner wall of the electrode housing, a cathode component fixedly connected to the upper surface of the isolation frame, and a set of anode components evenly distributed and fixedly connected to the inner wall of the electrode housing. The isolation frame serves to separate the inner space of the electrode housing into an upper compartment and a lower compartment, where the cathode and anode components are fixed respectively. When the electrolyte solution evaporates or leaks, the separated electrodes prevent the module from burning, ensuring safety and extending the module's service life. A detection cover is fixedly connected to the lower surface of the electrode housing. This detection cover will detect the evaporation or leakage of the electrolyte solution and send a signal to remind the user, further improving safety.

A calibration circuit board is fixedly connected to the inner wall of the calibration sleeve. A calibration processor and a pressure sensor are electrically connected to the upper surface of the calibration circuit board. This calibration mechanism improves the accuracy of the module's measurements. Atmospheric pressure affects the air intake inside the module, causing deviations in the values detected by the device. When the module is in use, the pressure sensor detects the current atmospheric pressure and transmits the information to the calibration processor. After measuring the oxygen content, the calibration processor corrects the value to obtain a more accurate value.
[0007] Preferably, filter plates are fixedly connected to the inner walls of the left and right shells of the shielding cover. The filter plates increase the shielding cover's ability to isolate interference and radiation. At the same time, the structure composed of several thin plates facilitates heat dissipation.

The silver plating layers further increase the shielding cover's ability to isolate interference and radiation. The outer walls of the left and right shells of the shielding cover are rotatably connected to the outer wall of the calibration sleeve.
[0008] Preferably, a set of oblique holes are evenly distributed on the lower surface of the electrode housing, which lead to the inner wall of the detection hood. When the electrolyte solution evaporates or leaks, it will flow into the detection hood, which facilitates detection. A detector is fixedly connected to the inner wall of the detection hood. The detector will detect the evaporation and leakage of the electrolyte solution and send a signal to remind the user, which improves safety. A support frame is provided on the upper surface of the electrode housing, a vent tube is sleeved on the inner wall of the electrode housing, and a sleeve mechanism is provided on the outer wall of the electrode housing.

This sleeve mechanism serves to protect the electrode mechanism, and the double-layer sleeve increases the stability of the structure, ensuring the normal operation of the module.
[0010] Preferably, the inner wall of the lower inner cylinder is provided with an electrode holder, the inner wall of the electrode holder is fixedly connected to the outer wall of the electrode housing, and the inner wall of the lower inner cylinder is provided with a fitting groove, the inner wall of the fitting groove is movably connected to the outer wall of the detection cover. By fixing the electrode mechanism on the electrode holder and fitting the detection cover into the fitting groove, the electrode mechanism is more securely fixed and connected, ensuring the operational safety of the module.
[0011] Preferably, a set of hooks are evenly distributed on the inner wall of the upper inner cylinder, and an air guide valve is fixedly connected to the outer wall of the set of hooks. A sealing ring is movably connected to the inner wall of the upper inner cylinder. The outer wall of the air guide valve is movably connected to the outer wall of the sealing ring. The upper surface of the upper inner cylinder is rotatably connected to the lower surface of the calibration sleeve. The output hole of the air guide valve is fixedly connected to the upper surface of the air pipe. The air guide valve is installed by hooks, and the sealing ring is used at the connection between the air guide valve and the upper inner cylinder to allow internal air circulation, ensuring the sealing of the module and improving the accuracy of module testing.
[0012] Preferably, an output circuit board is fixedly connected to the lower surface of the lower inner cylinder. The outer walls of the left and right shells of the shielding cover are movably connected to the outer wall of the calibration sleeve. A set of support feet is electrically connected to the terminals of the output circuit board. A connecting circuit board is electrically connected to the outer wall of the set of support feet. The module is connected to the connecting circuit board for use through the support feet. The module and the connecting circuit board will clamp the shielding cover mechanism, which facilitates the installation of the shielding cover mechanism.
[0013] The present invention has the following beneficial effects:
[0014] 1. The radiation generated during the operation of the oxygen transfer module first reaches the filter plate. The several sheet-like structures enable the filter plate to absorb as much radiation as possible. The radiation is further isolated by the subsequent left and right shielding shells and silver plating layer. The shielding shell mechanism can also isolate external interference and radiation to the oxygen transfer module in the reverse direction. At the same time, the sheet-like structure of the filter plate facilitates the absorption of heat generated during the operation of the oxygen transfer module and dissipates heat through the left and right shielding shells.
[0015] 2. When detecting the oxygen content of the current environment, the air first enters the module's air inlet after being filtered through a filter screen and a ventilation membrane. The air pressure sensor detects the current atmospheric pressure and transmits the information to the calibration processor. Then, the air enters the interior of the electrode mechanism through the air guide valve and the ventilation pipe. The air undergoes a chemical reaction inside the electrode mechanism, thereby enabling the calibration processor to obtain the current oxygen content of the environment. After calibration with the atmospheric pressure value, the accurate environmental oxygen content is obtained.
[0016] 3. The left and right shells of the shielding cover are connected by rectangular buckles and rectangular slots, and the oxygen transfer module is clamped inside them. Then, the output circuit board is inserted into the bottom groove of the shielding cover mechanism to enhance the tightness of the connection of the shielding cover mechanism. The module is connected to the connecting circuit board through the support feet. The module and the connecting circuit board will clamp the shielding cover mechanism, realizing the joint installation of the oxygen transfer module and the shielding cover mechanism.
