Detailed Description
The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 5, the invention provides a range hood, which comprises a hood body 1, a fume collecting hood 2, a baffle 3, a connecting port 4, a push rod motor 5, a microphone 6, a mounting bracket 7, a first motor 8 and a microphone bracket 9.
The smoke ventilator body 1 comprises a smoke collecting hood 2 and a smoke ventilator panel arranged at the periphery of the bottom end of the smoke collecting hood 2. The front end face of the panel of the range hood, which is close to a user, is provided with a display area for displaying the working state of the range hood and/or a control area for controlling the range hood. The panel of the range hood is also provided with a square connecting port 4, and the connecting port 4 is communicated with a microphone mounting structure arranged inside the range hood body 1. The microphone 6 is provided with a movable member that moves relative to the connection port 4 and a sliding device that slides relative to the connection port 4. The sliding device is a push rod motor 5. The push rod motor 5 comprises a motor body and a sliding block arranged on the motor body in a sliding mode, the microphone bracket 9 is fixed on the sliding block, and the microphone 6 is arranged on the microphone bracket 9.
The movable part is a square baffle 3 slightly larger than the connecting port. The opposite sides of the connection port 4 are provided with two mounting brackets 7 for mounting the baffle 3. The baffle 3 is rotatably mounted on a mounting bracket 7 about a rotation axis parallel to the side of the connection port 4. The baffle 3 has a first position for closing the connection port 4 and a second position for leaving the connection port 4 during rotation. The first motor 8 is arranged on the outer side of the mounting bracket 7, and the output shaft penetrates through the mounting bracket 7 to be connected with the baffle plate 3 so as to drive the baffle plate 3 to rotate between a first position and a second position.
When the user uses the microphone 6, after the first motor 8 receives a signal, the first motor 8 drives the baffle 3 to be opened from the connection port 4, and then the push rod motor 5 pushes the microphone 6 out of the microphone mounting structure after receiving the signal, and the microphone is extended to an externally preset extending position through the connection port 4. When the user finishes using Bi Maike wind 6, after receiving the signal, push rod motor 5 will microphone 6 to be located the storage position of microphone mounting structure, later after receiving the signal, first motor drive baffle 3 seals connector 4. By the arrangement, when the range hood is operated daily and the microphone 6 is used, the connecting port 4 which is communicated with the outside through the microphone mounting structure is opened through the movable part, so that the voice of the user can be obtained.
