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 volute for a centrifugal fan, which comprises a volute tongue having an inner wall; wherein, the volute tongue has an enclosed noise-reducing chamber, the volute tongue has a plurality of holes for allowing the air flow to enter into the noise-reducing chamber; and a sound collector and a speaker are disposed in the noise-reducing chamber. In the present invention, during the use of the centrifugal fan, a gas flow can enter the cavity through the holes on the inner wall. The sound collector can acquire a noise signal and transmit it to a controller, and the controller calculates a noise-reduced audio signal according to the acquired signal and then controls the speaker to play the corresponding reduced noise according to the noise-reduced audio signal, so that the active noise reduction is realized. With such a structure, the vortex at the volute tongue is eliminated, thus the fan noise is reduced and the fan efficiency is improved.
