[0029] Preferably, in this embodiment, the processor 200 not only has traditional data processing and control functions, but also integrates IOT (Internet of Things) capabilities such as OTA (Over-The-Air) upgrades, so that it can not only continuously maintain the latest software status, but also seamlessly connect with other smart devices to form an intelligent kitchen ecosystem. This design not only improves the user's cooking experience, but also enhances the practicality and safety of the device, making it a truly intelligent kitchen companion.

[0030] In order to realize active interaction with the user, in this embodiment, a camera 400 is provided which is in communication connection with the processor 200 and electrically connected with the start switch 300, and the camera 400 is turned on and off synchronously with the start switch 300, and when in the on state, it can continuously recognize the human body image and form a user status characteristic signal to feed back to the processor 200. This design enables the camera 400 to automatically enter the working state after the range hood is started, and feed back the user status characteristic signal to the processor 200 in real time, so that after the range hood is started, without user operation, the processor 200 can analyze the user's state and send a signal to the display screen 500, so that the display screen 500 can actively interact with the user according to the user's real-time state and provide personalized services, which greatly improves the intelligence level of the range hood.

[0031] In this embodiment, the camera 400 is detachably disposed below the side of the smoke hood 110 facing the user. This design, on the one hand, enables the camera 400 to obtain a wider field of view and better capture the user's behavior, posture and expression, thereby ensuring that the processor 200 can accurately analyze the user's emotional state; on the other hand, it improves the convenience of disassembly and assembly of the camera 400.

[0032] In this embodiment, two groups of cameras 400 are provided and arranged symmetrically relative to the center line of the range hood body 100, and the two groups of cameras 400 are respectively threadedly connected to the smoke hood 110. This design provides two different shooting angles, which can form a stereoscopic vision, so that the camera 400 can capture the user's more comprehensive behavior and expression, effectively improving the accuracy of emotion recognition and behavior analysis. The threaded connection method ensures that the camera 400 is firmly installed and will not loosen or shift, effectively ensuring the stability of the shooting effect. On the other hand, it also allows the camera 400 to adjust the angle as needed, ensuring the best shooting effect.

[0033] Preferably, in this embodiment, each group of cameras 400 is provided with a threaded portion 410 , and the smoke collecting hood 110 is provided with threaded holes corresponding to the two groups of cameras 400 one by one.

[0034] In this embodiment, the user status characteristic signal includes facial expression information and / or body posture information and / or age information and / or gender information. This design provides rich basic data for the processor 200 to analyze the user's emotions and status, so that the processor 200 can analyze the user's status more comprehensively and provide more accurate services.

[0035] Specifically, the camera 400 continuously captures the user's facial expressions, and the processor 200 analyzes the user's micro-expression changes through the AI ​​algorithm to identify the user's emotional state (such as happiness, frustration, anxiety, confusion, etc.). This analysis is not limited to static expressions, but also includes dynamic expression changes, which can more accurately capture the user's emotional fluctuations. If the user shows a smile and a relaxed posture, the processor 200 can judge that the user is in a happy state. At this time, the display screen 500 can display relaxed and humorous subtitles or expressions to create a pleasant cooking atmosphere. If the user shows anxiety or stress such as frowning and tight shoulders, the processor 200 can judge that the user may feel nervous or uneasy. At this time, the display screen 500 can display relaxation guidance words to help the user relieve emotions. If the user shows a sad or depressed expression, the display screen 500 displays comforting words to provide emotional support. In addition, according to the user's emotional state, recipes suitable for the current mood can also be recommended. For example, when the user feels tired, some simple and quick dishes can be recommended; when the user is in a good mood, some more creative or complex dishes can be recommended to increase the fun of cooking.

[0036] In addition to facial expressions, the camera 400 can also monitor the user's body movements in real time, such as gestures, body posture, head movements, etc. This body information can help the processor 200 determine the user's concentration level, fatigue level, and whether they need to rest or adjust their posture. For example, when it is detected that the user maintains the same posture for a long time, the user can be reminded to move appropriately to avoid muscle fatigue.

[0037] Through image recognition technology, the processor 200 can estimate the age range of the user and provide personalized services according to different age groups. For example, for young users, more creative recipes can be recommended; for older users, simpler and easier-to-make dishes can be recommended, or larger fonts can be displayed on the display screen 500 for easier reading.

[0038] In addition, the processor 200 can also provide differentiated services according to the gender characteristics of the user. For example, for female users, more recipes related to health and beauty can be recommended; and for male users, more high-protein and high-energy recipes can be provided.
