Abstract
Description
Technical Field
[0001] This utility model belongs to the field of kitchen equipment technology, and specifically relates to a kitchen equipment monitoring device. Background Technology
[0002] Kitchen monitoring equipment helps kitchens accurately control air quality by detecting the concentration of pollutants such as cooking fumes and non-methane hydrocarbons in real time, reducing harmful gas emissions, protecting the health of staff, assisting catering establishments in environmental compliance, optimizing energy consumption, and promoting green and sustainable development.
[0003] A known authorized patent with application number 202420873749.6 discloses a kitchen fume detection device, including an oil fume duct, an installation base fixedly installed inside the oil fume duct, a socket connected inside the installation base, a limit hole on the surface of the socket, and a detection component on the rear side of the socket. This kitchen fume detection device allows for quick installation and removal of the socket and oil fume detection probe by rotating the component to drive a threaded rod to rotate in both directions, causing the threaded rod to drive the insertion component into or out of the limit hole. This avoids the problems of existing kitchen fume detection devices where the oil fume detection probe is fixed inside the oil fume duct with bolts, requiring tools for disassembly and installation during cleaning or replacement, which is not only cumbersome but also easily leaves workers covered in oil stains. It also prevents the fixing bolts from slipping on tools after being contaminated with oil, reducing maintenance difficulty and time.
[0004] However, during the implementation of the relevant technology, the following problems were found with the above technical solution: When in use, the device can only detect flue gas, but it lacks a detection component for non-methane total hydrocarbon gases, resulting in a limited detection range. It cannot detect different substances in the air, making it difficult to detect hazards in a timely manner. Furthermore, since oil fume purification devices are currently used in accordance with environmental protection requirements, this device cannot monitor the usage of the oil fume purification device.
[0005] Therefore, a kitchen waste monitoring device is proposed to solve the above problems. Utility Model Content

[0029] The technical solution provided in this embodiment is as follows: In use, the device is first fixed to a wall or other object. During fixing, nails are driven into the inner ring of the fixing lug 10 to secure the device. Then, the Hall element 23 is connected to the outer wall of the power cord of the purification device. The device can then be started. The Hall element 23 constantly monitors the start-up status of the purification device to prevent it from not being turned on during operation. If it remains closed for an extended period, an alarm signal is transmitted to the speaker 7 via the alarm 5, which outputs sound as a reminder. The air pump 31 starts, drawing air through the spiral coil 33 into the interior of the non-methane total hydrocarbon gas detector 32. The internal component concentration is analyzed, and the spiral coil 33 allows for the installation of a longer pipeline in a smaller space, avoiding the influence of external environmental factors such as steam on the non-methane total hydrocarbon gas detector 32. The air pump 31 continuously pumps air into the non-methane total hydrocarbon gas detector 32, enabling the device to continuously detect the air. At the same time, the humidity sensor 9 and temperature sensor 8 detect humidity and temperature. When the indoor temperature increases sharply or reaches a high value, the alarm 5 will automatically sound an alarm. The particulate matter sensor 4 can detect the particulate matter content in the air in a timely manner, ensuring more accurate monitoring data.

[0032] Furthermore, the detection component 3 includes an air pump 31, a non-methane total hydrocarbon gas detector 32, and a spiral coil 33. The air pump 31 is fixedly installed inside the air pump 31, the non-methane total hydrocarbon gas detector 32 is installed at the input end of the air pump 31, one end of the spiral coil 33 is fixedly connected to the input end of the non-methane total hydrocarbon gas detector 32, and the spiral coil 33 penetrates the outer shell 1.
[0033] Specifically, by setting up the non-methane total hydrocarbon gas detector 32, various substances in the air can be detected in a timely manner, and then the excessive substances in the air can be analyzed.
[0034] Furthermore, an installation ring 6 is provided inside the outer casing 1, a horn 7 is fixedly installed on the inner wall of the installation ring 6, and an alarm 5 is provided inside the outer casing 1.
[0035] Specifically, through the settings of alarm 5, a warning can be issued via speaker 7 when air pollution levels exceed the standard.
[0036] Furthermore, a temperature sensor 8 is installed inside the housing 1, with the detection end of the temperature sensor 8 penetrating through the housing 1. A humidity sensor 9 is also installed inside the housing 1, with the detection end of the humidity sensor 9 penetrating through the housing 1.
[0037] Specifically, the temperature sensor 8 and humidity sensor 9 can detect the air humidity and temperature in the space in real time. When the temperature rises rapidly, the alarm 5 can sound an alarm and the speaker 7 can alert the user, thus promptly detecting any potential dangers.
