Detailed Description
In order to make the technical problems, technical schemes and beneficial effects solved by the utility model more clear, the utility model is further described in detail below with reference to the embodiments.
Examples
The motor wind scooper shown in fig. 2 to 5 includes a housing body 10 and a tapered member 20 which are integrally injection molded, the housing body 10 having a circular passage C with both ends of the circular passage being a wind inlet hole 11 and a wind outlet hole 12, the tapered member being disposed in the circular passage. The conical part 20 divides the circular channel into two chambers, the chamber corresponding to the inlet opening 11 being the front chamber 50 and the chamber corresponding to the outlet opening 12 being the rear chamber 60.
The conical part comprises an inner ring plate 21 and an outer ring plate 22, the outer ring plate 22 being connected to the side wall of the circular channel by a connection 23. The inner ring plate is connected to the outer ring plate at one end corresponding to the front chamber through a ring plate 24, and the connecting portion includes two parallel plate members 231, one side of each plate member is connected to the side wall of the circular channel C, and the other side is connected to the outer ring plate 22.
