Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purification testing, in particular to an oil fume generating device. Background Art

[0002] Existing oil fume generators used for testing all utilize an electric stove and frying pan. These tests utilize a system of oil (or water) droplets that are heated and vaporized to generate oil fume. Their application is limited to vertical test benches, and the entire device is bulky, making it unsuitable for small, ducted test benches. The pan itself is difficult to clean and is a consumable item. During the generation of oil fume, non-directional splashing is inevitable, and there is even the risk of open flames. These methods differ significantly from the oil fume generated during actual cooking and cannot fully simulate the everyday household fume scene. Consequently, the calibration results of the oil fume detector may not accurately reflect its operational status. To ensure that the calibration results of the oil fume detector are based on the actual cooking process, a fume generator that can simulate the fumes of actual cooking is required.

[0003] For example, the Chinese utility patent with application number: CN202120232890.4 discloses an "oil fume generator", including an oil fume generating device and a mixing and smoke extraction device, the oil fume generating device includes: an oil fume generating chamber, the oil fume generating chamber is provided with: a control system, the control system includes a temperature control system and an air volume adjustment system; a heating oil pot, which is connected to the temperature control system; a heating water cylinder, which is connected to the temperature control system; a smoke guide pipe, which is respectively connected to the heating oil pot and the heating water cylinder, and one end of the smoke guide pipe extends to the outside of the oil fume generating chamber, and the other end is provided with an air volume adjustment system; the mixing and smoke extraction device is arranged outside the oil fume generating chamber, and includes: a mixing cylinder, the air inlet end of which is connected to one end of the smoke guide pipe, and the air inlet end is a conical structure; a smoke exhaust pipe, which is connected to the air outlet end of the mixing cylinder.

[0004] While the above solution can achieve precise oil temperature control, continuous, stable, and controllable smoke generation, and evenly distribute the smoke within the mixing cylinder, reducing the introduction of systematic errors during sampling, it still fails to truly simulate household oil smoke conditions, resulting in the calibration results of the oil fume detector not accurately reflecting its operating status. Summary of the Invention

[0005] In response to the problem mentioned in the background technology that the oil fume generating device in the prior art cannot truly simulate the oil fume of the actual cooking process, the present application provides an oil fume generating device, which is highly integrated through PLC and controls parameters such as temperature, weight, and pump speed to achieve automatic and precise oil control. It can be used in multiple scenarios, especially horizontal test benches, and is easy to disassemble and clean.

[0006] The second invention purpose of the present application is to solve the problem that during the generation of oil smoke, non-directional splashing is inevitable and may even cause the danger of open flames.

[0007] In order to achieve the above-mentioned purpose, an oil fume generating device is disclosed, comprising: a controller component, including a PLC controller and an oil fume source connected to the PLC controller; a heating furnace body, which vaporizes an oil-water mixture to generate oil fume; wherein the PLC controller controls the oil fume source to transport the oil-water mixture to the heating furnace body; wherein the heating furnace body is electrically connected to the controller component.

[0008] This device uses a PLC controller to control the oil fume source to deliver an oil-water mixture to the heating furnace, which then vaporizes the mixture to produce oil fume. The core of this design lies in the PLC controller, which enables precise control and ensures stable and controllable oil fume generation. The purpose of using a PLC controller is to precisely control the oil fume generation process. The PLC controller adjusts the oil-water mixture delivery rate in real time using a pre-set program, ensuring that the oil-water mixture vaporizes within the heating furnace at the optimal ratio, resulting in stable oil fume production. This precise control capability is unattainable with the traditional electric stove and frying pan method. The use of a PLC controller significantly improves the automation level and control accuracy of the oil fume generation device. Traditional methods rely on manual control and visual observation to ensure consistent oil fume generation. This device, however, achieves automated control through the PLC controller, improving experimental repeatability and reliability while also reducing operator error.

[0009] Compared with existing technologies, the greatest advantage of this device lies in its high degree of automation and integration. The traditional electric stove + frying pan method is large, cumbersome to operate, difficult to clean, and the fume generation process poses safety hazards, such as non-directional splashing and possible open flame hazards. This device solves these problems through the combination of a PLC controller and a heating furnace. The design of the heating furnace ensures the directional injection of fume, reducing the risk of contamination in the experimental environment. At the same time, the split structural design makes the device more flexible and portable, suitable for a variety of test benches, especially horizontal test benches.

[0010] Notably, the design of this device not only achieves precise control over the fume generation process but also allows for future expansion and upgrades. By varying program settings, the device can simulate various cooking scenarios, more realistically simulating the fume-generating conditions of everyday life. This flexibility and scalability are unmatched by traditional methods, demonstrating both technological innovation and foresight.

[0011] Furthermore, a four-way valve is provided between the oil fume source and the heating furnace body, and the oil fume source includes a water pump, an oil pump, and an air pump, which are respectively connected to the four-way valve. The structure of the four-way valve can accurately control the flow rate and mixing ratio of the three media: oil, water, and gas, and transport the mixture to the heating furnace body for gasification. Traditional oil fume generating devices usually lack a precise fluid control mechanism, resulting in unstable oil fume generation and difficulty in simulating a real cooking environment. The application of a four-way valve can achieve precise control of oil, water, and gas, ensuring the controllability and consistency of the oil fume generation process. First, through precise fluid control, the stable generation of oil fume is ensured, avoiding experimental errors caused by unstable flow. Second, this solution avoids the blockage problem that may be caused by a single oil circuit or water circuit, thereby improving the reliability and durability of the system. In addition, the use of an air pump can also simulate the participation of air in the cooking process, making the generated oil fume closer to the actual home cooking scene. Specifically, traditional oil fume generators typically use a simple oil-water mixing heating method, lacking precise control over the oil, water, and gas, which can easily lead to unstable oil fume generation, non-directional splashing, and even the risk of open flames. This solution, however, combines a four-way valve with a water pump, an oil pump, and an air pump to achieve precise control of the oil, water, and gas. This not only improves the stability of oil fume generation, but also effectively avoids the risk of non-directional splashing and open flames.

[0012] Preferably, the water pump and the oil pump are both peristaltic pumps. Peristaltic pumps are used as water pumps and oil pumps to achieve precise metering and delivery of water and oil. The peristaltic pump squeezes the hose through the rotating pump head, thereby generating suction and pressure, and can accurately control the flow rate. This ensures that the ratio of water and oil delivered to the heating furnace is accurate, thereby ensuring that the state and concentration of the oil fume smoke ultimately generated can be precisely controlled, better simulating the oil fume generated by actual cooking. Compared with common electronic or mechanical metering methods, the use of a peristaltic pump can achieve more accurate water and oil metering, which is an innovation. This precise control is conducive to simulating oil fume smoke that is closer to actual cooking, so that the calibration results of the oil fume detection equipment can better reflect the actual situation, thereby improving the accuracy of the detection. In addition, the peristaltic pump has a simple structure and is easy to maintain and replace, which is conducive to the long-term and stable operation of the equipment.

[0013] Preferably, the oil pump is connected to an oil pot, and a weighing sensor is provided at the bottom of the oil pot, and the weighing sensor is electrically connected to the PLC controller. The weighing sensor detects changes in the amount of oil in the oil pot in real time and feeds the data back to the PLC controller. The PLC controller adjusts the delivery speed of the oil pump based on the actual changes in the detected oil volume, thereby accurately controlling the amount of oil delivered to the heating furnace. This ensures that the ratio of the oil-water mixture in the heating furnace is accurate, thereby generating oil fume smoke that is more similar to actual cooking. Common oil fume generating devices are generally unable to accurately control the amount of oil released, making it difficult to achieve an accurate simulation of the oil fume situation during actual cooking. By providing an oil pot at the outlet of the oil pump and equipping it with a weighing sensor, oil consumption can be monitored in real time, and precise oil volume control can be achieved by coordinating the adjustment of the PLC controller and the oil pump. This can better reproduce the oil fume generated during actual cooking and improve the calibration accuracy of the oil fume detection equipment. This solution can monitor and precisely control the amount of oil delivered to the heating furnace in real time, thereby generating oil fume smoke that is more similar to actual cooking. At the same time, it improves the automation and precise control capabilities of the heating device and enhances the calibration effect of the detection equipment; 3) By automatically adjusting the oil volume, the need for manual intervention and maintenance is reduced, and the equipment is more convenient to use.

[0014] Preferably, the heating furnace body includes a heating chamber and an evaporation core disposed within the chamber. The evaporation core is connected to the outlet of a four-way valve. The heating chamber is provided with a directional groove. The four-way valve mixes water, oil, and gas delivered by the water pump, oil pump, and air pump, and then passes the mixture through the evaporation core into the heating chamber. Under the heating action of the heating chamber, the water and oil are vaporized into oil smoke. The directional grooves in the heating chamber guide the generated oil smoke toward a specific direction, preventing non-directional splashing. This design better simulates the characteristics of oil smoke generated during actual cooking and improves the calibration accuracy of detection equipment. Compared to the common method of simply heating oil or water, this technology incorporates an evaporation core within the heating chamber, ensuring thorough mixing and vaporization of water, oil, and gas, generating oil smoke that more closely resembles actual cooking. Furthermore, the directional grooves in the heating chamber guide the direction of oil smoke emission, preventing non-directional splashing and enhancing safety and simulation accuracy.

[0015] Furthermore, a temperature sensor is provided in the heating furnace body, and the temperature sensor is electrically connected to the PLC controller. The temperature sensor can monitor the temperature changes inside the heating furnace body in real time and feed back the data to the PLC controller. Based on the temperature feedback, the PLC controller can finely control the heating power of the heating furnace body to ensure that the interior of the heating furnace body maintains an ideal constant temperature state. This can ensure that water and oil can be fully vaporized inside the heating furnace body to generate stable and uniform oil fume smoke. Setting up a temperature monitoring and feedback mechanism can ensure that the temperature inside the heating furnace body is within the optimal range to obtain an ideal oil fume gasification effect. During the heating process of common oil fume generating devices, the temperature control is often rough and it is difficult to maintain a constant temperature state, which will cause the state of the oil fume smoke to be unstable, thereby affecting the calibration accuracy of the detection equipment. By using a built-in temperature sensor and linking it with a PLC controller, more accurate temperature monitoring and adjustment can be achieved, ensuring the controllability and repeatability of the heating process and improving the performance and applicability of the oil fume generating device.

[0016] Preferably, the controller assembly includes an interactive display screen, which is connected to a PLC controller and controls the ratio and temperature of the oil-water mixture. The interactive display screen can realize human-machine interactive control of the equipment operating parameters, including adjusting the ratio of the oil-water mixture and the temperature of the heating furnace body. Setting up an interactive display screen increases the flexibility of manual intervention on the basis of ensuring automatic control. Through the interactive display screen, the operator can freely adjust the oil-water ratio and temperature settings according to actual needs to generate oil smoke in different states. This human-machine interactive function is conducive to simulating the characteristics of oil smoke generated in various cooking scenarios, thereby improving the pertinence and applicability of the calibration of the detection equipment. The operator can adjust key parameters at any time according to needs to achieve refined control of the oil smoke generation state, thereby better meeting the needs of different detection scenarios. This design not only enhances the applicability of the equipment, but also improves the user experience, which is conducive to its promotion and use in practical applications.

[0017] Preferably, an auxiliary shield is provided on one end of the heating furnace body, near the directional slot. This shield is made of a high-temperature-resistant polymer material. The primary purpose of this shield is to reduce the environmental pollution caused by the high-temperature, high-pressure oil smoke generated by the heating furnace body. Without this shield, the high-temperature, high-pressure oil smoke would easily splash around, contaminating the surrounding environment. This auxiliary shield, made of a high-temperature-resistant material, effectively blocks and collects this splashing oil smoke, preventing the spread of pollution.

[0018] This design, to a certain extent, addresses the safety risks and environmental pollution issues associated with common oil fume generating devices. Installing this auxiliary shield at the outlet not only reduces the splashing of oil fume, but also protects the equipment from high temperatures and high pressures, improving its safety and reliability.

[0019] The detachable guard plate facilitates equipment maintenance and cleaning. Over extended use, oil fume contaminants may accumulate on the surface of the auxiliary guard plate. Failure to easily remove and clean the auxiliary guard plate can negatively impact equipment operation. This detachable design significantly improves equipment maintenance and extends its service life. The auxiliary guard plate effectively addresses the safety and environmental challenges of common oil fume generating devices, reducing splash pollution and contributing to long-term reliable operation.

[0020] Therefore, the present invention has the following beneficial effects:

[0021] (1) It can precisely control the proportion of water, oil and gas, generating a state that is more similar to the oil smoke produced during the actual cooking process, thereby improving the accuracy of the detection equipment calibration.

[0022] (2) The use of automated control technologies, such as PLC control and temperature monitoring feedback, can achieve fine control of the oil fume generation process, ensure the stability and repeatability of oil fume smoke, and further improve the calibration effect of the detection equipment.

[0023] (3) The innovative design of the directional spray mechanism and auxiliary guard plate can effectively avoid the non-directional splashing of high-temperature and high-pressure oil smoke, reduce the safety hazards of equipment use, and reduce pollution to the surrounding environment.

[0024] (4) The use of a detachable and easy-to-clean design, such as the quick-plug interface between the heating furnace body and the controller assembly, and the detachable auxiliary protective plate, improves the maintenance convenience of the equipment and extends its service life.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figure 1 、 2 As shown, a fume generating device includes: a controller assembly 1, including a PLC controller and an oil fume source connected to the PLC controller; a heating furnace body, which vaporizes an oil-water mixture to generate oil fume; wherein the PLC controller controls the oil fume source to deliver the oil-water mixture to the heating furnace body; wherein the heating furnace body is electrically connected to the controller assembly; and an interactive display screen 2, which is connected to the PLC controller and controls the ratio and temperature of the oil-water mixture.

[0031] A four-way valve 11 is provided between the oil fume source and the heating furnace body. The oil fume source includes a water pump 7, an oil pump 6 and an air pump 5 respectively connected to the four-way valve. The water pump 7 and the oil pump 6 are both peristaltic pumps. The oil pump 6 is connected to an oil pot 4. A weighing sensor 3 is provided at the bottom of the oil pot 4. The weighing sensor 3 is electrically connected to the PLC controller. The heating furnace body includes a heating furnace cavity and an evaporation core provided inside the heating furnace cavity. The evaporation core is connected to the outlet of the four-way valve. An orientation groove is provided on the heating furnace cavity. A temperature sensor is provided in the heating furnace body. The temperature sensor is electrically connected to the PLC controller. An auxiliary protective plate 15 is provided on one end of the heating furnace body near the orientation groove. The auxiliary protective plate 15 is made of a high-temperature resistant polymer material.

[0032] The core of the oil fume generating device disclosed in this scheme is to realize the automation and intelligent control of the oil fume generation process through a set of precise control systems, so as to generate a state that is more similar to the oil fume generated during the actual cooking process, and provide a more reliable simulation environment for the calibration of oil fume detection equipment.

[0033] Overall, the device consists of three main components: a controller assembly, a heating furnace, and an auxiliary protective plate. The controller assembly integrates functional modules such as temperature control, water, oil, and gas flow regulation, and weight monitoring, all coordinated and managed by an intelligent control system with a PLC at its core. The heating furnace heats and vaporizes the water, oil, and gas mixture supplied by the control system, generating oil smoke. The auxiliary protective plate collects and directs the oil smoke, preventing splash contamination caused by high-temperature, high-pressure oil smoke. These three components work together to form an oil smoke generation system that combines precise control, stable generation, and safe protection.

[0034] Specifically, the controller assembly is the "brains" of this device. It integrates core components such as a PLC controller, temperature sensor, water pump 7, oil pump 6, air pump 5, and weight sensor. These components utilize sophisticated PID algorithms and feedback control to monitor and adjust the water, oil, and air supply ratios in real time, ensuring precise control of the mixed gasification process within the heating furnace. For example, the weight sensor collects real-time data on the oil level changes in the oil tank 4 and feeds it back to the PLC controller, which automatically adjusts the speed of the oil pump 6 to precisely control the amount of oil delivered to the heating furnace. Simultaneously, the temperature sensor within the heating furnace transmits real-time temperature data to the PLC, enabling precise control of the heating power and ensuring a constant temperature during the heating process. This automated control mechanism ensures repeatable and reliable oil fume generation, helping to simulate oil fume conditions that more closely resemble actual cooking.

[0035] The heating furnace body consists of a precisely machined heating chamber 13 and an evaporation core 14. The control system delivers the prepared mixture of water, oil, and gas to the evaporation core 14. Under the heating action of the heating chamber, this mixture is fully vaporized and transformed into a stable oil smoke cloud. It is worth mentioning that the heating chamber adopts a double-layer insulation and sealing structure, which not only ensures good temperature stability but also effectively reduces oil leakage and contamination. At the same time, the evaporation core design can also be replaced according to different usage requirements, making this device adaptable to a variety of complex application scenarios.

[0036] Furthermore, the design of the auxiliary protective plate further enhances the practicality of this device. When high-temperature, high-pressure oil smoke and fumes are ejected from the heating furnace, they can easily cause non-directional splashing, polluting the surrounding environment. This protective plate, made of high-temperature-resistant polytetrafluoroethylene, effectively collects and guides this smoke, ensuring a stable discharge in a predetermined direction and preventing random splashing. Furthermore, the removable design of the protective plate facilitates routine maintenance and cleaning of the equipment, significantly extending the device's service life.

[0037] Overall, the overall design of this oil fume generating device embodies the principles of precise control, stable generation, and safe protection. The controller component ensures precise delivery of water, oil, and gas at a constant temperature through intelligent, automated control, generating high-quality water-oil fume. The ingenious structural design of the heating furnace also ensures an efficient and stable gasification process. The auxiliary protective plate eliminates the splashing contamination problem common with conventional devices, enhancing overall safety. These innovative design features enable this device to effectively simulate the characteristics of oil fumes generated during actual cooking, providing a more reliable basis for the calibration of oil fume detection equipment.

[0038] It's worth mentioning that the device's split design also demonstrates excellent user-friendliness. Aviation-grade quick-connect connectors connect the controller assembly to the heating element, making it extremely convenient to disassemble and carry the entire unit. Furthermore, the controller assembly incorporates a human-machine interactive display screen2, allowing operators to adjust parameters such as the water-to-oil ratio and temperature through an intuitive touch interface to meet the needs of various application scenarios. This flexibility and customizability are advantages not found in conventional oil fume generators.

[0039] From an automation perspective, the device utilizes an intelligent control system centered around a PLC, enabling precise regulation of the water, oil, and gas mixture ratio and temperature. This not only ensures repeatability and reliability in the fume generation process, but also helps simulate fume characteristics that more closely resemble actual cooking scenarios. Compared to traditional, simple heating methods, this device offers significantly greater automation capabilities, significantly improving the accuracy of test equipment calibration.

[0040] The device's sophisticated internal structural design is crucial for achieving optimal fume generation. The heating element utilizes a double-layer, thermally insulated, and sealed structure, ensuring excellent temperature stability and enabling the full vaporization of water, oil, and gas. Furthermore, the removable evaporation core design provides the device with enhanced adaptability, allowing for flexible switching to suit different application scenarios. These innovations effectively address the shortcomings of existing devices in terms of fume generation stability and applicability.

[0041] Furthermore, this device specifically addresses the safety hazards and environmental pollution issues commonly encountered with conventional devices. A high-temperature-resistant auxiliary protective plate at the outlet effectively collects and directs the high-temperature, high-pressure oil smoke, preventing non-directional splash pollution. This design not only enhances safety during use but also reduces environmental impact. Furthermore, the removable protective plate facilitates maintenance and further extends the device's service life.

[0042] In actual use, the oil fume generating device is relatively simple to operate. First, the controller assembly and the heating furnace body need to be connected via quick-connect connectors to ensure smooth data and power transmission between the two components. Then, according to actual needs, the water, oil, and gas supply lines are connected to the interfaces on the controller. The other ends of the water and oil pipes can be directly connected to water pump 7 and oil pump 6, while the gas line can be supplied by an external gas source.

[0043] Next, the required working parameters are set through the touch screen integrated in the controller component, that is, the interactive display screen 2. The operator can adjust the delivery ratio of water, oil and gas, as well as the temperature setting of the heating furnace body according to specific detection needs. These parameters can be stored as preset plans for subsequent repeated use. It should be noted that in order to ensure that the final generated oil smoke state is closer to the actual cooking process, it is recommended to use certain test data as a reference and gradually optimize the various parameter settings. After the parameters are set, the entire system can be started to work. The PLC built into the controller component will automatically coordinate the operation of the water pump 7, oil pump 6 and air pump 5, and adjust the flow rate in real time according to the feedback from the weight sensor to ensure that the mixing ratio of water, oil and gas remains in the optimal state. At the same time, the temperature sensor inside the heating furnace body will also transmit the real-time temperature data back to the PLC, which will adjust the heating power in time according to the feedback to keep the furnace body in the ideal constant temperature working state. Under this precise automatic control, the water, oil and gas mixture will be fully vaporized inside the heating furnace body and transformed into stable oil smoke. As Figure 1 As shown, an oil inlet pipe 8, an air inlet pipe 9 and a water inlet pipe 10 are connected between the controller assembly and the heating furnace body; and a temperature sensing line 12 is also connected to the PLC controller and the heating furnace body for receiving signals from the temperature sensor and feedback-controlling the heating temperature of the heating furnace body 13.

[0044] To prevent the non-directional splashing of high-temperature, high-pressure fumes, the device features an auxiliary protective plate at the furnace outlet. This high-temperature-resistant polytetrafluoroethylene (PTFE) material guides the fumes in a predetermined direction, effectively reducing pollution to the surrounding environment. The removable plate also facilitates regular cleaning and maintenance, extending the life of the equipment.

[0045] After the entire workflow is complete, the operator simply removes the heating element from the controller assembly to transfer the generated oil smoke to the equipment under inspection. This split design not only facilitates transportation and storage of the equipment, but also enhances its applicability to meet the needs of different application scenarios.

[0046] Overall, the overall operation of this oil fume generator is highly user-friendly and automated. Whether it's parameter setting, operational control, or equipment maintenance, it demonstrates a high level of intelligence. Compared to existing similar products, it offers significant improvements in accuracy, stability, and safety, undoubtedly providing a superior solution for oil fume detection.

[0047] It's worth noting that, in practical applications, the controller component of this device integrates several key functional modules. First, there's the temperature control module, capable of adjusting the furnace temperature from room temperature to 450°C. Next, there's the water pump 7 and oil pump 6, capable of delivering 1-10g / min of water and oil, respectively. Furthermore, an air pump 5 is integrated, providing a gas flow rate of 100-500ml / min. This can be operated from an external source or with a built-in air pump. Furthermore, a weight sensor with a range of 0-1kg is included to monitor changes in the oil level in the oil pot 4 in real time.

[0048] These core components are intelligently coordinated and managed by a PLC controller. The PLC utilizes a PID feedback control algorithm, automatically adjusting the speed of water pump 7 and oil pump 6 based on real-time data from the weight sensor, thereby precisely controlling the amount of water and oil delivered. The PLC also connects to the temperature sensor inside the heating furnace to monitor the heating temperature in real time and adjust the heating power based on the feedback signal to ensure a constant temperature.

[0049] The heating element consists of two main components: an evaporation core and a heating chamber. The evaporation core, measuring 195 x 50 x 10 mm, is specifically designed to vaporize the water, oil, and gas mixture from the controller assembly. The heating chamber features an integrated slotted design that precisely positions the evaporation core, ensuring the gas mixture is adequately heated. The entire heating element utilizes a double-layered, insulated, and sealed structure, effectively ensuring a constant temperature during heating while also reducing oil leakage and contamination.

[0050] During the exhaust process, a removable auxiliary protective plate designed for the furnace outlet is installed. Made of high-temperature resistant polytetrafluoroethylene, this plate effectively collects and guides the high-temperature, high-pressure oil smoke, ensuring a stable discharge in a pre-set direction and preventing non-directional splashing. The removable plate also greatly improves the equipment's maintenance convenience.

[0051] Overall, this solution fully embodies the integrated innovation of automated control, stable generation, and safety protection. From the controller assembly to the heating furnace body and auxiliary protective plate, each component is closely linked and works together to ensure the accuracy, stability, and safety of the oil fume generator.

[0052] Example 2

[0053] In addition to Example 1, this embodiment also proposes some expansion and extension solutions. For example, in the gas supply part, it is possible to consider using a blower with variable frequency speed regulation instead of the traditional air pump 5 to achieve more delicate air flow control. Alternatively, a new type of diffuser can be designed at the oil smoke ejection part to better simulate the diffusion characteristics of oil smoke during the actual cooking process. These technical points are likely to further improve the performance and applicability of this device. Regardless of the method adopted, the key is to fully meet the calibration requirements of the oil smoke detection equipment and restore the characteristics of the oil smoke generated during the actual cooking process as much as possible.
