Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The embodiment provides an air inlet duct structure, which is applied to a blower (particularly a high-speed blower) and is used for guiding the air inlet flow direction of the blower so as to reduce noise and vibration generated in the air inlet process of the blower.
Referring to fig. 1-3, the blower is provided with an air intake structure 2 at least at the handle thereof, and the air intake structure 2 is capable of taking air in the circumferential direction.
Specifically, the air inlet structure 2 is one of an air inlet (integrally formed on a handle bottom cover of the blower), an air inlet grille (integrally formed on the handle bottom cover of the blower) and an air inlet net (fixedly arranged at the bottom of the handle inner shell 1 of the blower and positioned at the inner side of the handle bottom cover of the blower, and at the moment, the handle bottom cover of the blower is also provided with an air inlet/air inlet grille); it will be appreciated that the air intake structure 2 is of annular or cylindrical configuration.
In order to guide the intake air flow direction of the blower, the intake air duct structure of the present embodiment includes an air guide wall 13; the air guide wall 13 is supported inside the air intake structure 2 of the blower for gathering the air flow inside the air intake structure 2 and guiding the air flow to the extending direction of the handle.
Specifically, the handle of the blower comprises a handle inner shell 1, the handle inner shell 1 is a shell made of engineering plastic, an air inlet duct 11 is formed in the handle inner shell 1, the air inlet duct 11 is communicated with an air inlet structure 2, and in practice, a strip-shaped cavity in the handle inner shell 1 is the air inlet duct 11 and is used for guiding air flow to a heating body positioned in the blower body; the bottom of the inner handle shell 1 is formed with a bottom extension bracket 12, the bottom extension bracket 12 is a strip-shaped bracket, the air guide wall 13 is connected to the free end of the bottom extension bracket 12 to support the air guide wall 13 on the inner side of the air inlet structure 2, and the number of the bottom extension brackets 12 is not limited, for example, three as shown in fig. 1 or two as shown in fig. 2.
Further, the handle inner shells 1 are arranged in opposite to each other, at this time, each handle inner shell 1 is a half shell, and the two handle inner shells 1 are buckled with each other into a whole or locked into a whole by screws.
Further, the wind guide wall 13 includes:
