[0002] The online oil fume monitoring device is an intelligent monitoring device that collects oil fume emission concentrations from kitchens and restaurants and uploads the collected data to a regulatory platform for environmental management and supervision. Through this device, regulatory authorities can remotely monitor the operation of catering companies' production and pollution control facilities, promptly detect illegal or leaky emissions, and reduce atmospheric pollutant emissions from catering companies, thereby improving atmospheric environmental quality.

[0003] Online oil fume monitoring equipment typically uses an electromagnetic pump to collect exhaust gas from the exhaust duct through a sampling tube and uses an oil fume sensor to detect the oil fume concentration.

[0059] Refer to the following Figures 1 to 4 The oil fume monitoring device and the oil fume online monitoring system according to the embodiments of the present application are described.

[0060] See also Figures 1 to 3 As shown, an embodiment of the present application provides an oil fume monitoring device, which includes a box body 150, a filter component 500, a protective component 600 and a power device 130, wherein the filter component 500, the protective component 600 and the power device 130 are all arranged in the box body 150, and the filter component 500, the protective component 600 and the power device 130 are sequentially connected in the box body 150, the filter component 500 can filter out most of the impurities in the oil fume airflow, and the gaseous oil in the oil fume airflow can be converted into liquid oil when flowing through the filter component 500; the protective component 600 is provided with an oil storage portion, the liquid oil in the oil fume airflow and the liquid oil intercepted by the filter component 500 can flow into the oil storage portion, so that the oil fume airflow can be secondary processed when flowing through the protective component 600, and the power device 130 is specifically an electromagnetic pump, which is used to extract the oil fume airflow and make the oil fume airflow flow in a directional manner, such as Figure 3 As shown (in Figure 3 In the figure, letter a represents the oil fume airflow flowing into the box body 150, letter b represents the exhaust gas filtered by the filter component 500, and letter c represents the liquid oil flowing to the protective component 600). When the power device 130 is started, the oil fume forms a directional airflow and flows into the box body 150, and the oil fume can pass through the primary filtration of the filter component 500 and the secondary treatment of the protective component 600, and the impurities and oil in the oil fume are filtered out before flowing to the electromagnetic pump, thereby reducing the oil content in the oil fume airflow flowing to the electromagnetic pump and reducing the probability of damage to the electromagnetic pump.

[0061] Furthermore, the housing 150 is provided with an air intake 300, through which oil smoke can flow into the housing 150. The oil smoke monitoring device further includes an oil smoke sensor 400, which is provided in the housing 150 and is close to the air intake 300.

[0062] The oil fume sensor 400 includes a main body and a detection probe disposed therein. The main body is provided with a first connection port and a second connection port. The first connection port is connected to the air intake port 300 via a first connection pipe. Oil fume entering the housing 150 through the air intake port 300 flows through the first connection pipe into the main body and through the detection probe. The oil fume sensor 400 is used to detect oil fume concentration. The oil fume flow then flows through the second connection port to the filter element 500. Preferably, the first connection pipe and each of the following connection pipes are preferably rubber hoses.

[0063] Furthermore, the housing 150 is provided with an oil drain port 700 and an exhaust port 800. The oil drain port 700 is connected to the protective member 600, and the oil accumulated in the oil reservoir can be discharged outside the housing 150 through the oil drain port 700. The drive device is connected to the exhaust port 800, and the oil smoke flowing into the housing 150 passes through the electromagnetic pump and is finally discharged outside the housing 150 through the exhaust port 800.

[0064] Preferably, the box body 150 has a top plate, a side plate and a bottom plate, the air intake port 300 is arranged on the top plate, or the air intake port 300 is arranged on the side of the side plate close to the top plate, the oil drain port 700 and the exhaust port 800 are arranged at intervals on the bottom plate, or the oil drain port 700 and the exhaust port 800 are respectively arranged on the side of the side plate close to the bottom plate.

[0065] In addition, the box 150 is also provided with a power line interface 110 for passing wires to connect to an external power source, so as to connect the circuit to the box 150 to power various electrical devices in the box 150.

[0066] Furthermore, the filter component 500 includes a main body, within which a filter is disposed. The main body also includes a third connection port and a fourth connection port. The third connection port is connected to the second connection port via a second connection pipe, allowing the oil fume flow passing through the oil fume sensor 400 to flow into the main body via the second connection pipe. The filter can filter the oil fume flow, and the oil fume flow filtered by the filter, along with liquid oil essence, flows to the next node via the fourth connection port. It should be noted that the filter in this embodiment is specifically a filter element, filter screen, or other filtering component commonly used in the prior art.

[0067] Furthermore, the protective member 600 includes a tank body, which is provided with a fifth connection port 601 and a sixth connection port 605. The fifth connection port 601 is connected to the fourth connection port via a third connection pipe. The oil fume flow from the filter member 500 flows into the tank body through the third connection pipe. During this process, the liquid oil in the oil fume flow and the liquid oil accumulated in the third connection pipe during the oil fume flow can flow into the tank body, thereby separating the liquid oil from the gaseous substances in the oil fume flow, and the liquid oil remains in the tank body. Preferably, within the housing 150, the protective member 600 is positioned lower than the filter member 500.

[0068] Furthermore, the internal space of the tank body forms an oil storage part, and a partition plate 608 is provided inside the tank body to separate the oil storage part into an oil accumulation chamber 606 and an oil collecting chamber 607.

The shape of the convex portion 6041 is adapted to the shape of the connecting hole 6081, so that the convex portion 6041 can be embedded in the connecting hole 6081. One end of the elastic support member 602 is connected to the lower surface of the blocking block 604, and the other end of the elastic support member 602 is connected to the bottom wall of the oil collecting chamber 607, so that the elastic support member 602 can always apply elastic force to the blocking block 604. The convex portion 6041 on the blocking block 604 can block the connecting hole 6081 to close the connecting hole 6081. The liquid oil flowing into the tank body is first accumulated in the oil accumulation chamber 606, and the gaseous airflow flows to the next node through the sixth connecting port 605, and the gas will not flow into the oil collecting chamber 607.

[0070] The oil collecting chamber 607 is provided with an oil outlet 603, preferably located at the bottom of the oil collecting chamber 607 and connected to the oil drain port 700 of the housing 150. When excessive oil accumulates in the oil collecting chamber 606, the blocking block 604 is subjected to a pressure greater than the elastic force of the elastic support member 602, which pushes the blocking block 604 downward, allowing the oil in the oil collecting chamber 606 to flow into the oil collecting chamber 607. Ultimately, the oil is discharged outside the oil fume monitoring device through the oil outlet 603 and the oil drain port 700.

[0071] Furthermore, the electromagnetic pump is provided with a seventh connection port and an eighth connection port, and the seventh connection port is connected to the sixth connection port 605 through a fourth connection pipe, so that after the electromagnetic pump is started, the oil fume airflow can flow through the oil fume sensor 400, the filter component 500, the protective component 600 and the electromagnetic pump in sequence.
