the one end of dwang is inside to be clamped there is the round bar, the one end fixedly connected with disc of round bar, the disc clamp in the inside of connecting plate.
Preferably, the spout has been seted up to the one end inside of dwang, the other end outer wall fixedly connected with card strip of round bar, card strip slip joint in the inside of spout.
Preferably, eight groups of clamping grooves are uniformly formed in the connecting plate, two groups of clamping blocks are symmetrically arranged on the outer wall of the disc, and the clamping blocks are clamped in the clamping grooves.
Preferably, a filter screen is fixedly installed at one side of the fan.
Preferably, a rotary button is fixedly connected to one side of the disc.
The working principle and the specific using process of the utility model are as follows: during the use, when the angle of blowing of fan need be adjusted, make disc and fixture block break away from the inside of connecting plate through pulling turn button, turn button at fan both ends simultaneously, under the combined action of card strip and spout, can make the disc drive round bar and dwang rotate together to make the angle of fan adjust, adjust certain angle back, promote turn button to one side, make the fixture block correspond the card in eight wherein two sets of draw-in grooves of group, and then fix the fan behind the angle of adjustment.
Compared with the prior art, the utility model has the beneficial effects that: this clean laminar flow cover of purification workshop liquid tank formula, through the setting of components such as laminar flow cover, fan and filter screen, through the cooperation of fan and filter screen, can act as the isolation air current layer of laminar flow cover, can separate the laminar flow cover when using with the ambient air through the isolation air current layer or can form the backward flow to avoid the air to flow back to the below of laminar flow cover, thereby further reduction pollution product, protection product that can be better. And then the fan can be adjusted at multiple angles by arranging the connecting plate, the rotating rod, the disc, the rotating button, the clamping groove, the clamping block, the round rod, the clamping strip, the sliding groove and other components, so that the angle of the isolation airflow layer can be changed, and the isolation range can be enlarged.
