Description
Technical field
The utility model relates to a kind of blower fan, particularly relates to a kind of blower fan for respiratory machine.
Background technique
The application of respiratory machine is more and more extensive, and respiratory machine is not only used in it sufferer, also can use respiratory machine when people go to plateau section to travel on official business.
What in respiratory machine, volume was maximum is exactly blower fan and air inlet supporting with it, to give vent to anger and the parts of sound insulation, what power consumption was maximum is also blower fan, air pressure required for respiratory machine and flow velocity produce by fan blade High Rotation Speed, under certain pressure and flow velocity, the larger rotating speed of blade diameter is slower, otherwise the less rotating speed of diameter is faster, the impeller diameter of current use is greater than 100 millimeters, blade is 6, rotating speed to turn left the right side 12000, and impeller material is aluminium, and impeller adopts aluminum to be stamped to form, Heavy Weight, exist power consumption large, be inconvenient to the shortcoming of carrying.
Model utility content
The technical problems to be solved in the utility model be to provide a kind of structure simple, be convenient for carrying, portable fan that power consumption is less.
The utility model portable fan, comprise spiral case lid, spiral case, impeller, high-speed brushless motor, described high-speed brushless motor is inner rotor motor, described impeller material adopts plastics, and adopt injection molding one-body molded, described impeller comprises center and establishes round-meshed upper cover plate, the lower cover plate be arranged in parallel with upper cover plate, multiple blade, multiple blade is evenly arranged along the center of lower cover plate upper surface, the upper end of each blade is all fixed with the lower end surface of upper cover plate, the lower end of each blade is all fixed with the upper-end surface of lower cover plate, often adjacent two blades and upper cover plate, all relief opening is formed between lower cover plate, the base plate center of described spiral case arranges center hole, described high-speed brushless motor is fixed in center hole, the output shaft of described high-speed brushless motor passes the center of the lower cover plate of impeller and fixes with lower cover plate, the described lower end of spiral case lid and the upper end of spiral case are fastened.
The utility model portable fan, wherein said impeller diameter is 100mm, and blade number is 8, and relief opening height is 8mm.
The utility model portable fan difference from prior art is that the utility model portable fan only includes spiral case lid, spiral case, impeller, a few part of high-speed brushless motor, and structure is simple; Impeller adopts plastics injection moldings one-body molded, upper cover plate, more firm between lower cover plate and blade, and weight is little, and power consumption is also little; And adopt plastic weigh comparatively light, be convenient for carrying.
In the utility model portable fan, impeller diameter is 100mm, blade number is 8, relief opening height is 8mm, comparatively in background technique, impeller diameter reduces to some extent, blade number increases, impeller diameter reduces the volume of blower fan is reduced, and take up room reduction, and blade number increases raising pumping efficiency.
Below in conjunction with accompanying drawing, portable fan of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model portable fan;
Fig. 2 is the main TV structure schematic diagram of impeller in the utility model portable fan;
Fig. 3 is the distribution map of Fig. 2 Leaf.
Embodiment
Composition graphs 1, 2, shown in 3, the utility model portable fan comprises spiral case lid 1, spiral case 2, impeller 3, high-speed brushless motor 4, high-speed brushless motor 4 is inner rotor motor, impeller 3 material adopts plastics, and adopt injection molding one-body molded, impeller 3 comprises the upper cover plate 5 that center is provided with circular hole 14, the lower cover plate 6 be arranged in parallel with upper cover plate 5, multiple blade 7, multiple blade 7 is evenly arranged along the center of lower cover plate 6 upper surface, the upper end of each blade 7 is all fixed with the lower end surface of upper cover plate 5, the lower end of each blade 7 is all fixed with the upper-end surface of lower cover plate 6, often adjacent two blades 7 and upper cover plate 5, relief opening 8 is all formed between lower cover plate 6, the base plate center of spiral case 2 arranges center hole 9, high-speed brushless motor 4 is fixed in center hole 9, the output shaft 10 of high-speed brushless motor 4 is also fixed by screw 11 and lower cover plate 6 through the center of the lower cover plate 6 of impeller 1, the lower end of spiral case lid 1 and the upper end of spiral case 2 are fastened.
Impeller 1 diameter is 100mm, and blade 7 number is 8, and relief opening 8 is highly 8mm.
Again as shown in Figure 1, spiral case lid 1 center arranges suction port 12, spiral case 2 outer surface arranges the air outlet 13 be communicated with spiral case 2 inside, during use, air sucks from suction port 12, via circular hole 14, relief opening 8, discharge from air outlet 13 again, airintake direction is vertical with discharge directions, and air is pressurized directly, and pumping efficiency is higher.
In the utility model, the material of impeller is plastics, and compared with employing aluminium, much lightweight, fan starting is faster, the lightweight vane rotary of motor belt motor, low in energy consumption, power consumption is low, and rotating speed also has lifting.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
