As Figure 1-Figure 2, a kind of low noise fan blade structure is present embodiments provided, including big flabellum 31, small flabellum 32
And wheel hub 33, the big flabellum 31, small flabellum 32 are an integral structure and are made of aluminum alloy material, the big flabellum 31
There is grafting block with the end set of small flabellum 32, spliced eye is provided on the wheel hub 33, the grafting block is inserted into the grafting
In hole, the two is fixedly connected by bolt.
Wherein, the big flabellum 31 is three, is uniformly arranged along the 33 side periphery interval of wheel hub, the small flabellum 32
Three are similarly, is arranged between big flabellum 31, is uniformly arranged along the 33 side circle spacing of wheel hub, the big flabellum 31
Swivel plate is more than the radius of turn of the small flabellum 32.
Fan blade structure in traditional technology is a type of multiple flabellums compositions, is 3-6 flabellum, flabellum sheet as by
The one side width of nearly wheel hub 33 is small, and the one side width away from wheel hub 33 is big, therefore, in use, when wheel hub 33 drive it is more
When a flabellum rotates, the axial velocity of each 33 one end of flabellum adjacent hub certainly will be less than separate
The axial velocity of 33 one end of wheel hub will so cause the axial velocity profile that air enters fan unequal, cause
Air quantity caused by 33 one end of flabellum adjacent hub is less than flabellum away from air quantity caused by 33 one end of wheel hub.Difference on this air quantity
It is different, between air-flow caused by different position on flabellum, pressure differential will be formed, therefore make fraction towards wheel hub 33
Direction is flowed, and the turbulent flow of rotational flow is easily formed at the position close to wheel hub 33, can disturb the discharge of whole air-flow, and
The heat dissipation of fan is greatly reduced.Therefore, the application sets 32 two groups of fan blade structures of big flabellum 31 and small flabellum, on evading
State defect.
Correspondingly, a kind of air-cooler is additionally provided, including driving motor 22 and fan blade structure, the driving motor 22 is logical
The housing for crossing connecting rod and air-cooler connects, and the middle part of the wheel hub 33 is provided with axis hole, the driving motor 22 it is defeated
Shaft is inserted into the axis hole, and the output shaft and axis hole can be interference fit mechanisms, and the wheel hub 33 is driven to rotate.
In addition, as shown in figure 3, in order to further reduce noise, the chimney fan of the air-cooler of the application is arranged to double-deck knot
Structure, it is double-deck between for cavity, be uniformly arranged multiple air holes 102 on inner wall, and cavity along it is distinguished and admirable to direction on, by between
Spacer ring 101, is isolated into multiple cavities, using such structure design, can further reduce noise.
The air-cooler of the application in the water tank of bottom in the process of running, it is necessary to add water, consequently facilitating water pump leads water
In wet curtain 6, cool down to wind.In use, after using a period of time, water can be dirty, it is necessary to replace water, operates
Come it is more bothersome, therefore, this application provides a kind of filtration cycle mechanism, as shown in figure 4, including the row being arranged on air-cooler
Water pipe 7 is sequentially connected the first water pump 8, Rose Box 9 (using 9 structure of Rose Box in public technology), the by circulating line 10
One valve 11 is connected with water inlet pipe 15, and the water circulating filter in water tank is carried out by the first water pump 8, reduces time for replacing water
Number；In addition, currently adding water to water tank, carry out manually adding water from water inlet pipe 15, it is time-consuming and laborious.Therefore, the application, which is provided with, mends
Water dispenser structure increases the second water pump 13, the second valve 12 and extra feed tank 14, replenishing water tank of water on the basis of filtration cycle mechanism
It is connected by the supply pipeline for being provided with the second water pump 13, the second valve 12 with circulating line 10.When carrying out circulating filtration,
The first valve 11 is opened, closes the second valve 12, when carrying out moisturizing, the second valve 12 is opened, closes the first valve 11.
In addition, in order to realize the automation control of the mechanism, in water tank liquid level sensor and lower liquid level is set to pass
Sensor, the upper liquid level sensor and lower liquid level sensor, the first water pump 8, the second water pump 13, the first valve 11, the second valve
12 grades of door are connected with controller, by being configured in advance in controller, realize the works such as automatic cycle filtering, automatic water supplement
Make.
As shown in figure 5, the air-cooler of the application is provided with water level monitoring floating ball 16, including floating ball body 161, connection with holes
Bar, band axis pin connecting rod 162, the band axis pin connecting rod 162 is provided with clamping portion 163, the pin with axis pin connecting rod 162
Axis is interference fitted with the connecting rod with holes, and can be rotated around axis pin, and the clamping portion 163 is stuck on air-cooler housing, with institute
The cooperation of air-cooler body clearance is stated, it is thus possible to realize, when the water level in water tank goes up, floating ball body 161 rises,
It the one end for causing clamping portion 163 exposed, can be according to the variation of this observation water level to the bottom.
Wet curtain 6 is both provided on four side walls of the air-cooler of the application, can enter the wind, improve refrigerating efficiency.
The application is the improvement based on existing air-cooler, and the part-structure of wherein air-cooler is not shown, these are not shown
Structure and the unmodified structure that shows the structure of the existing air-cooler having disclosed may be employed.
The above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
