[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] The following is in conjunction with the appendix Figure 1-2 This application provides a further detailed description. An embodiment of this application discloses a wireless oil quality monitoring sensor, including a hollow housing 1. The housing 1 has a detection port 101 for insertion into the oil to be tested. A processing core 2 is located inside the housing 1, connected to a detection electrode 3. The detection electrode 3 is positioned at the detection port 101 and contacts the oil for detection. The processing core 2 processes the electronic data detected by the detection electrode 3. The housing 1 also includes a built-in power supply (not shown) and a wireless antenna (not shown) connected to the processing core 2. The built-in power supply powers the processing core 2, the wireless antenna, and the detection electrode 3, while the wireless antenna transmits the detection data to an external data receiving device.

[0017] Furthermore, the processing core 2 includes a signal acquisition board 201, a core motherboard 202, and a transmitter board 203 connected in sequence. Specifically, the signal acquisition board 201 is closer to the detection electrode 3, the transmitter board 203 is closer to the wireless antenna, and the core motherboard 202 is located in the middle. The electronic data detected by the detection electrode 3 is first acquired by the signal acquisition board 201, and after being analyzed and processed by the core motherboard 202, the transmitter board 203 transmits the processed data through the wireless antenna.

[0018] Furthermore, the housing 1 includes a detection unit 110, an equipment unit 120, and a battery unit 130 that are detachably connected in sequence. A detection port 101 is located in the detection unit 110, the processing core 2 is located in the equipment unit 120, and the built-in power supply and wireless antenna are located in the battery unit 130. This segmented design allows for modular assembly of the entire device, facilitating future maintenance and replacement.

[0019] Furthermore, since the built-in power supply is typically quite heavy and its operating environment is unpredictable, a vibration damping pad 4 is provided between the device section 120 and the battery section 130 to prevent vibrations from the entire device during use from impacting the processing core 2. The vibration damping pad 4 buffers the vibrations of the built-in power supply, protecting the processing core 2 from impact damage. The vibration damping pad 4 can be made of elastic materials such as silicone or rubber. The vibration damping pad can serve as an intermediary connecting the device section 120 and the battery section 130, or it can be installed as an internal component at the connection point between the device section 120 and the battery section 130 after the device section 120 and the battery section 130 are connected.

[0020] Furthermore, the built-in power supply can be a rechargeable power supply completely integrated into the battery section 130 of the housing 1, and charged via a power cord connected to a charging port on the surface of the housing 1. Based on the portability of this invention, the built-in power supply can also be a replaceable built-in power supply, such as a battery. Thus, the battery section 130 is further divided into two detachably connected structures: a battery compartment 131 and a battery cover 132. The connection between the battery compartment 131 and the battery cover 132 can be a conventional detachable connection technology, such as an interference fit or a threaded connection.

[0021] Furthermore, to enable this invention to be fixedly connected to a device or pipeline, the outer wall of the detection port 101 is provided with a connecting structure. The connecting structure can be a thread as shown in the embodiment, or other conventional connecting structures corresponding to the external connection port. Correspondingly, elastic sealing measures such as sealing rings can be provided in the connecting structure to prevent oil from overflowing from the connecting structure.

[0022] Furthermore, to expand the functionality of the device, a temperature sensor is also provided at the detection port. The temperature sensor is electrically connected to the processing core 2, enabling this invention to detect the oil temperature while simultaneously detecting the oil quality. Specifically, in this embodiment, the temperature sensor is a PT1000 temperature sensor.

[0023] Furthermore, a display screen electrically connected to the processing core 2 can be installed on the outside of the housing 1 to display relevant data in real time.

[0024] Working principle: A battery is installed, powering on the processing core 2, detection electrode 3, wireless antenna, and other electronic devices, putting them into operation. The detection port 101 of the detection unit 110 is inserted into the oil to be tested, causing the detection electrode 3 inside the detection port 101 to contact the oil. The detection electrode 3 generates electronic signals, producing electronic data which is transmitted to the processing core 2. The processing core 2 processes the electronic data and then transmits the signal to an external receiving device via the wireless antenna.
