Description
Technical field
The utility model relates to rotary pump pumping elastic fluid, particularly relates to working fluid and is air and with electrically driven (operated) pumping installations controlling component, particularly relates to and significantly manual tune can fan the electric fan at the head elevation angle.
Background technique
Electric fan generally includes fan head, fan blade and supporting base, and described fan head comprises again forward and backward housing, motor, horizontal oscillating mechanism and fan head mechanism for regulating elevation angle.Prior art electrical fan head mechanism for regulating elevation angle comprises two kinds of mode of structure:
One, fanning head bottom inserts in supporting base, with the pivot joint of cylinder bolt, also relies on fan head to insert the frictional force fixed fan head elevation angle of supporting base contact segment by its screw head tightening.First screw is unscrewed when adjusting this elevation angle, then buttress fan head front portion and up lift or toward pressing down, finally tightening screw and fixing.Although this kind of adjust structure is simple, but regulation range is too little, can only be generally that 10 ° of < fan head elevation angle <+30 °, adjustment process is cumbersome again, fan head after using a period of time can naturally droop under gravity, and electric wire exposes also unsightly, also easy tong.
Two, on front a kind of mode of structure basis, increase and the detorsion spring that opposing fan head sinks and the banking stop controlling the fan head elevation angle are set, and the decorative pearl on top of an official cap and decorative pearl on top of an official cap spring.Described improved procedure does not keep the elevation angle by surface of contact frictional force, but offsets fan head sinking gravity by torsion spring, keeps the fan head elevation angle by banking stop, the decorative pearl on top of an official cap and decorative pearl on top of an official cap spring.Advantage is easy to adjust, and the elevation angle keeps, shortcoming: regulation range is little, and power line exposes unsightly, installation, maintenance difficulty, easy tong.
The above-mentioned fan head elevation angle, see Fig. 8, means the angle α of fan head motor axis line O and horizontal plane L; Horizontal plane L above α > 0, below horizontal plane L, α < 0.
