Embodiment
Referring now to accompanying drawing 1-2, it is described as follows with reference to embodiment：
A kind of simple apparatus for demonstrating of gas pressure intensity and flow velocity relation, including blower fan 2, base body 1, described blower fan 2 connect
Power supply is connect, blower fan 2 is provided with power knob 22 and speed governing button 21, and speed governing button 21 can adjust the wind speed size of blower fan 2, institute
Blower ventilation pipeline 3 is provided with before the blower fan 2 stated, described blower fan 2 is fixed on base body 1, and described base body 1 is integral note
Modeling is formed, and screw is provided with base body 1, and described blower fan 2 is bolted in screw, on described base body 1
Provided with fixed groove A 14, fixed groove B 13 and fixed groove C 12, described fixed groove B 13 is arranged on base body 1
Middle part, front and rear sides are respectively equipped with one；Described fixed groove A 14 is in front side fixed groove B 13 left side, institute
The fixed groove C 12 stated is plugged with paper tape 4 in front side fixed groove B 13 right side, described fixed groove A 14, described
Anterior planting 5 is plugged with front side fixed groove B 13, rear side fixed plate 15 is plugged with the rear side fixed groove B 13,
Fixed mount B 16 is fixed between the anterior planting 5 and rear side fixed plate 15, fixed mount B 16 can be used to fixed common
Transparent pipeline 17, the transparent pipeline 17 are corresponding with conically shaped；The anterior planting 5, rear side fixed plate 15 and fixation
Frame B 16 is that integrated injection molding forms, ratchet 6 of the anterior planting 5 provided with internal messing formula, in the rear side fixed plate 15
Provided with circular hole, the fixed mount B 16 is made up of conically shaped, front rod and rear connecting rod, and conically shaped is fixed on front rod
And between rear connecting rod；Front end is provided with active reel 8 on the front rod, and brake pawl 7 is provided with active reel 8,
Rocking bar 9 is provided with the centre of front end active reel 8, the front rod is fixed on anterior planting 5, and the front side is fixed
The mechanism of ratchet 6 of front rod composition internal messing formula on ratchet 6 and fixed mount B 16 on plate 5, the described mechanism of ratchet 6
It can only can not be rotated to a direction rotating rocker 9, opposite direction, brake pawl 7 is braked, and the rear connecting rod is plugged on rear side
In fixed plate 15；Right side fixed plate 11 is plugged with the fixed groove C 12, the integrated injection molding of right side fixed plate 11 forms,
It is made up of middle connecting plate, left connection board and right connection board, the middle connecting plate is fixed between left and right connecting plates bottom,
