In the figure: 100 centrifugal fan shell, 200 base, 300 outer shell, 301 ejector rod, 400 cleaning box, 401 handle, 402 baffle, 403 cleaning opening, 404 hook.
Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
As shown in fig. 1 to 2: the embodiment provides a fan with an anti-blocking structure, which comprises a centrifugal fan shell 100 and a base 200 connected with the centrifugal fan shell 100, wherein the base 200 is positioned at the bottom of the centrifugal fan shell 100 and supports the centrifugal fan shell 100 to a certain height, a gap is formed between the lower part of the centrifugal fan shell 100 and the ground, the gap is required to meet the installation and use requirements of a cleaning device, meanwhile, the base 200 adopts a frame structure, and all sides of the frame are open, so that the periphery of the cleaning device is basically exposed to the outside, and the assembly and the use of the cleaning device are facilitated.
In order to realize the internal anti-blocking effect of the centrifugal fan, a cleaning device connected with the cleaning device is installed in a gap at the lower part of the centrifugal fan shell 100 and is located inside the base 200 to ensure the safety of the cleaning device in the transportation and installation processes, the cleaning device comprises an outer shell 300 and a cleaning box 400 detachably connected with the outer shell 300, wherein:
the outer shell 300 is fixedly connected with the centrifugal fan shell 100, the side face of the front side of the outer shell 300 is of an open structure, the cleaning box 400 is placed into the outer shell 300 at the open position and is communicated with an opening at the bottom of the centrifugal fan, and a handle 401 is mounted on the front side of the cleaning box 400, so that the operation and the use are convenient; simultaneously, the inside cavity height of shell body 300 is greater than the high setting of clearance box 400, just the bottom of shell body 300 still is equipped with ejector pin 301 rather than being connected, the bottom surface threaded connection of ejector pin 301 and shell body 300, and the bottom of ejector pin 301 is equipped with the hand wheel rather than being connected for rotatory ejector pin 301 goes up and down to use, and the top of ejector pin 301 is equipped with a tight piece in top, the tight piece in top and the bottom surface contact of clearance box 400, and upwards jack-up clearance box 400 sets up, make clearance box 400 with carry out sealing connection through sealed pad etc. between the opening of centrifugal fan casing 100.
