Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1~6 As shown, the blower fan 5 of this embodiment includes a casing 51, a motor 52 and an oil filter 1, the motor 52 is arranged in the casing 51, the casing 51 has an air inlet 511, and the oil filter 1 is fixed on the air inlet 511. The oil screen 1 has an oil filtering hole 10 .

[0026] The oil filter screen 1 of this embodiment includes a plurality of annular ventilation surfaces 11, and the oil filter screen 1 is sequentially connected by at least three ventilation surfaces 11 in the radial direction to form an oil filter main body 100, and the adjacent ventilation surfaces The inclination direction of 11 is different and presents the ups and downs wavy structure in the radial direction, and each ventilating surface 11 is all opened with oil filter hole 11. Each annular ventilation surface 11 is a concentric ring, a...

Abstract

The invention relates to a fan. The fan comprises an outer shell, a motor and an oil filter screen. The motor is arranged in the outer shell, the outer shell is provided with an air inlet, and the oilfilter screen is arranged on the air inlet. The fan further comprises a cleaning brush and a clutch mechanism, the cleaning brush is rotatably arranged on the outer surface of the oil filter screen,and the clutch mechanism is disposed in the outer shell and used for driving the cleaning brush to be connected with or disconnected from an output shaft of the motor. The cleaning brush of the fan isselectively connected to the output shaft of the self-contained motor of the fan through the clutch mechanism, when an extractor hood is in a state of absorbing cooking fumes, the cleaning brush canbe disconnected from the output shaft of the motor through the clutch mechanism, so that the cleaning brush is static relative to the oil filter screen, and the effect of absorbing the cooking fumes is not affected; when absorption of the cooking fumes is completed and the extractor hood is switched to a self-cleaning state, the cleaning brush can be connected to the output shaft of the motor through the clutch mechanism, and the fan is started to enable the cleaning brush to rotate relative to the oil filter screen, so that oil stains on the oil filter screen are scraped off, and the filter screen is kept clean; and the extractor hood has a better self-cleaning effect.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a filter fan and a range hood using the fan. Background technique [0002] In recent years, people's living standards have been continuously improved, and people's awareness of health and environmental protection has been increasing. People are eager to have a healthy, clean and environmentally friendly home kitchen environment. Chinese patent CN200710051289 discloses an air dust centrifugal purification device and a manufacturing method of a rotary oil filter. The rotary oil filter is composed of a skeleton of the oil filter and a radial radial filter that is evenly wound around the periphery. The above-mentioned oil filter net is wound by a filter wire, and the manufacturing method is complicated, and the filter wire is easy to corrode and break, and the filter wires are densely interlaced in the middle area of ​​the oil filter net, resulting in large oil fume wind resistan...
