Embodiment
As shown in Figure 2, be first embodiment of the invention.Installed dividing plate 4 additional in blade 3 inboards.As shown in the figure: ventilation fan 200 is made of flabellum, motor 5, framework 2, switch curtain 1 and dividing plate 4; This motor 5 is fixed in the middle part of framework 2; This flabellum is installed on the axle of motor 5; This switch curtain 1 is installed in a side of framework 2 opening portions, and switch curtain 1 is made of the blade 3 of plural number, and the axle 6 of each blade 3 is fixed on the framework 2; Dividing plate 4 is fixed on the inboard of switch blind blade 3, is preferably to be shaped in switch blind blade inboard.When switch curtain 1 was closed, this dividing plate 4 was positioned at the space that switch curtain 1 and framework 2 surround; When switch curtain 1 was opened, dividing plate 4 rotated and outwards rotates along with blade 3, is forming obstacle between the blade 3 and between blade 3 and frame inner wall 7.After staff touched blade 3 accidentally, because the stopping of dividing plate 4, staff can't continue to stretch between the blade 3 or gap between blade 3 and frame inner wall 7 and touch flabellum.
The shape of dividing plate 4 can be a different shape, when needing only switch curtain 1 closure, can be positioned at the space that switch curtain 1 and framework 2 surround; And when switch curtain 1 is opened, can rotate and outwards rotate and get final product along with blade 3.Be preferably number of plate-shaped thing or bar.These number of plate-shaped things or bar are fixed on the blade 3, distribute around motor 5.On blade 3 also can before and after divide to arrange and put these tablets or bar.
Please referring to Fig. 3, this figure is a second embodiment of the invention, and figure central diaphragm 4 is run into frame inner wall 7.Be further to increase Security, switch curtain 1 can not complete opening in the present embodiment, and this point is different with first embodiment.When switch curtain 1 was opened, frame inner wall 7 was run in any position of dividing plate 4, and switch curtain 1 is stopped operating, thereby makes switch curtain 1 be in half-open position.
Please referring to Fig. 4, this figure is a third embodiment of the invention, and figure central diaphragm 4 is run into motor 5.Different is when switch curtain 1 is opened with Fig. 3, and any position of dividing plate 4 is run into motor 5 positions and allowed switch curtain 1 stop operating, thereby makes switch curtain 1 be in half-open position.
Among above-mentioned second, third embodiment, because switch curtain 1 is in half-open position, gap between blade 3 and the blade 3, between blade 3 and the frame inner wall 7 is all littler than first embodiment, and between the switch blind blade 3, the existence of dividing plate 4 is arranged between blade 3 and the frame inner wall 7, also can't continue to stretch into and touch flabellum even therefore there is staff to touch blade accidentally between the blade 3 or gap between blade 3 and the frame inner wall 7.
As shown in Figure 5, this figure is a fourth embodiment of the invention, and dividing plate 4 is positioned at around the motor 5.As shown in the figure, around motor 5, extend number of plate-shaped thing or bar, be preferably and be shaped on the motor 5.These tablets or bar form a net.As staff accidentally between blade 3 or the gap between blade 3 and the frame inner wall 7 when stretching into since above-mentioned number of plate-shaped thing or bar stop that staff can't touch flabellum 8.
As shown in Figure 6, this figure is a fifth embodiment of the invention, and dividing plate 4 is fixed on the frame inner wall 7.As shown in the figure, extend number of plate-shaped thing or bar, be preferably and be shaped on the inwall at frame inner wall 7.These tablets or bar form a net.As staff accidentally between blade 3 or the gap between blade 3 and the frame inner wall 7 when stretching into since above-mentioned number of plate-shaped thing or bar stop that staff can't touch flabellum 8.
As shown in Figure 7, this figure is a sixth embodiment of the invention.Increase the quantity of blade 3 in the present embodiment, make blade 3 gap turn narrow.As shown in the figure, the space h between the blade 3, and space h ' or h between blade 3 and the frame inner wall 7 " less than the width of finger; generally speaking, such as h, h, or h " during less than 10mm, the finger of staff is because the stopping of blade 3, just can't stretch into smoothly in the framework 2 and touches flabellum.
As shown in Figure 8, this figure is an eighth embodiment of the invention, increases the length of framework 2 in the present embodiment.When the height H of framework during greater than the hand length of staff, generally speaking, such as H during greater than 150mm, staff can't stretch into smoothly in the framework 2 and touch flabellum.
