Referring to fig. 1-4, a fan inlet box, including shell 1, shell 1 includes air inlet portion 101 and wind-collecting portion 102, air inlet portion 101 is the one end fixedly connected with wind-collecting portion 102 that tubaeform structure and internal diameter are minimum, the top fixedly connected with air-out fan housing 2 of wind-collecting portion 102, air outlet 8 that suits with air-out fan housing 2 is seted up at the top of wind-collecting portion 102, the inboard of wind-collecting portion 102 is provided with an installation section of thick bamboo 3 and installation section of thick bamboo 3 passes through bracing piece and shell 1 fixed connection, three induced air baffle 5 can be dismantled to the inboard of air inlet portion 101, demountable installation has filter assembly 6 between induced air baffle 5 and the installation section of thick bamboo 3, the bottom of air-out fan housing 2 is provided with a plurality of cylinder 9, all cylinder 9 all rotate with shell 1 through the bracing piece and are connected, bracing piece one end rotates with cylinder 9 through the pivot with shell 1 fixed connection and the other end.
The scheme has the following working processes:
when the air inlet box of the fan is used, the horn-shaped air inlet part 101 can enlarge the size of an air inlet and can suck air from more directions, when the air flow passes through the air inducing partition plate 5, the air flow can be naturally divided into three layers of air flows, so that the air flow at the center or the periphery of the air inlet is guided to a uniform flow direction, when the air is discharged, the air flow can drive the roller 9 to roll, the air flow in the uniform direction is formed around the roller 9, the air flow is added into the air flow at the rear part, and the air is uniformly discharged.
According to the working process, the following steps are known:
the air inlet box of the fan can unify the flow direction of air when air is sucked and exhausted, thereby reducing the influence of turbulent air flow and reducing the energy consumption of the fan.
Further, the size of three induced air baffle 5 evenly reduces in proper order and all is the tubaeform structure that suits with air inlet portion 101, and the axis of three induced air baffle 5 all coincides and is the three-layer stacked structure distribution from inside to outside, through bracing piece fixed connection between three induced air baffle 5, then can be cut apart into three-layer air current from inside to outside when the induced air baffle 5 is flowed through to gas for the gas everywhere that is located the air intake inboard all can be driven to unified flow direction by the air current.
Further, filter assembly 6 includes support ring 12 and filter screen 13, and the outer wall of support ring 12 is laminated with the inner wall of shell 1 mutually, and the inboard fixedly connected with filter screen 13 of support ring 12 can play the effect of impurity in the filtered air, avoids impurity to arouse the condition of fan trouble.
Further, be located the equal fixedly connected with collar 7 of the inner wall of the induced air baffle 5 of inlayer and filter screen 13 in three induced air baffle 5, collar 7's inner wall, corresponding screw thread has all been seted up on the outer wall of spliced pole 4 and the inner wall of installation section of thick bamboo 3, collar 7, spliced pole 4 and the connection of closing soon of 3 accessible screws of installation section of thick bamboo, then after long-term the use, can dismantle down filter component 6 and induced air baffle 5 through unscrewing installation section of thick bamboo 3 and spliced pole 4 and collar 7, convenient washing.
Furthermore, all the rollers 9 are distributed in a circular array, and the center of the array is located on the central axis of the air outlet cover 2, so that the airflow direction can adapt to the shape of the air outlet 8, and the uniform discharge of air is facilitated.
Furthermore, a groove 10 is formed in the outer wall of the roller 9, a felt layer 11 is fixedly connected to the inner portion of the groove 10, and the felt layer 11 can increase the friction force between air and the roller 9 and can form air flow more easily.
In conclusion, the cooperation between each part and the structure not only provides conditions for forming airflow with uniform flow direction, but also reduces the difficulty of forming uniform airflow, filters the gas passing through the air inlet box, and comprehensively improves the practicability of the air inlet box of the fan.
