摘要： A protection device for an oil-smoke sensor has a protection housing having two ends and an inner chamber; the first end having a first opening for receiving a probe of the oil-smoke sensor and in communication with the inner chamber; a second opening is disposed on the second end which is opposite to the first opening and in communication with the inner chamber. Because the probe is sealing mounted in the first opening, the probe will not be directly exposed in oil-smoke flow. The protective device is mounted such that the axial direction of the protective device is vertical to the oil-smoke flow direction. Therefore, the inner chamber of the protection housing has a pressure with respect to the oil-smoke flow that tangentially flows at a high speed, and the oil-smoke can only be diffused into the protection housing, thus, the probe is much less likely to be contaminated.

摘要： The present invention discloses a lifting mechanism for a moving component of a range hood and a range hood with the same, which comprises a mounting frame, a moving component, a motor, a transmission mechanism, two lifting rods, a connecting member and two guide rails. The transmission mechanism moves the connecting member up and down along the guide rails, so that the lifting rods and the moving component are allowed to move up and down. The power for the lifting motion is provided by the transmission mechanism, the guide rails on two sides ensure the stability of the lifting motion, and the lifting rods fixed on two sides of the connecting member further transfers the motion downward to the smoke guide plate, so that the lifting motion of the smoke guide plate is very stable.

摘要： The present invention discloses an intelligent range hood and a control method thereof, which comprises a housing, a fan (4), a smoke collecting hood (3), a smoke guide plate (6), a controller and a sensor (8) for detecting concentration of smoke and/or vapor inside or outside the housing. The sensor (8) outputs an electrical signal to the controller; and, the controller controls rotation speed of the fan motor (5) and position of the smoke guide plate (6) according to the signal received from the sensor (8). The controller not only can automatically adjust the rotation speed of the fan motor (5) so as to allow the air volume of the fan (4) to adapt to the working condition of the range hood in real time, but also can adjust the air inlet area and the distance between the negative pressure region and the smoke source by moving the smoke guide plate (6) up and down, so as to adapt the change in the working condition.

摘要： A real-time fume concentration monitoring system includes an electrical box having a closed internal space, wherein a divider is disposed within the electrical box so that the internal space of the electrical box is divided into a first chamber and a second chamber; a signal emitting unit is disposed within the first chamber, and a signal receiving unit is disposed within the second chamber; a portion of the electrical box corresponding to a signal emitting portion of the signal emitting unit and signal receiving unit is a light-transmitting region; a signal output terminal of the signal receiving unit is connected to a data processing unit. By detecting the fume concentration in a contactless manner, power consumption is low, the energy efficiency demand for the whole machine in the standby state is satisfied, and the signal detection sensitivity is high.
