Description
Technical field
The utility model relates to a kind of electric tool more particularly to a kind of hair dryers.
Background technique
Hair dryer is also a kind of common electric tool, and structure design is highly developed.But in industrial use,
The biggest problems are that duration.Continuous use hair dryer will lead to casing fever, influence the service life of entire hair dryer, together
When also bring along security risk.In order to solve this problem, also there are many solutions, such as the patent No. in the prior art:
201620949742.3 utility model " hand blower " in disclose a kind of hand blower, including blower
(1), casing (3), stator (4), rotor (5), windward disk (8), fan blade (9), leeward disk (10), the fan blade (9) includes wind
Leaf dish (14), fan blade disc (14) are equipped with and are linked together and equally distributed several cyclone type arc shaped blades (15), fan blade disc
(14) the triangle aileron piece (11) for being correspondingly provided on excircle and being linked together per a piece of cyclone type arc shaped blade (15), phase
Be correspondingly provided with ventilation hole (13) on fan blade disc (14) between adjacent cyclone type arc shaped blade (11), the side of ventilation hole (13) with it is upper
Air inlet (7) on wind disk (8) is corresponding, and the other side of ventilation hole (13) is corresponding with motor radiating air inlet (6)；Rotation
It is smoothly transitted and is connect by arc fillet (12) between wind formula arc shaped blade (15) and triangle aileron piece (11).Using this structure
Afterwards, have simple and reasonable, firm and reliable connection, wind-force is powerful, wind pressure is stable, can long time continuous working, service life
The advantages that long.
But hair dryer in the prior art considers the problem of fan blade disc intensity, can not design heat release hole excessive.
Two problems are brought in this way, first is that heat release hole is too small, heat dissipation effect is limited；Second is that noise can be generated during running at high speed.
Utility model content
The purpose of this utility model is to provide a kind of hair dryers, are improved on the basis of existing hair dryer, into one
Step improves the effect of heat dissipation, while also reducing noise when wind machine itself uses.
In order to realize the purpose, a kind of hair dryer of the utility model, including the motor being mounted in casing and connection
Fan blade on motor, the fan blade include fan blade disc and air blade, and the fan blade disc is equipped with heat release hole, face shared by heat release hole
Product is the 1/4-1/3 of fan blade disc surface area, and radiates bore edges at least in 3 centimetres of fan blade disc outer edge, the heat release hole
Equipped with strengthening rib strip.
Preferably, the edge shape of the heat release hole edge shape matching air blade.Two fan blades can be made full use of in this way
Space between piece.
Preferably, the junction between the strengthening rib strip is set to heat release hole edge.Due to the junction of strengthening rib strip
Bigger connection area is needed, therefore design can reduce strengthening rib strip area shared in heat release hole in heat dissipation bore edges,
Improve the space utilization rate of heat release hole.
Preferably, the strengthening rib strip has gradient, and inclined direction is consistent with fan blade rotation direction.Such structure subtracts
The windage of strengthening rib strip is lacked.
Preferably, the strengthening rib strip surface is with heat dissipation burr.Which not only adds the radiating surfaces of heat dissipation hole surface
Product, while also avoiding forming turbulent flow in heat dissipation hole site, influence the effect of outlet air.
Preferably, the strengthening rib strip projected area is lower than the 1/10 of heat release hole projected area.
Preferably, heat release hole is evenly distributed on fan blade panel surface.Ensure fan blade disc uniform force in this way, is hardly damaged.
Being mainly characterized by for the utility model is compared with similar product, under the premise of not influencing the intensity of fan blade disc,
Heat dissipation hole area is improved, the air output and radiating efficiency of complete machine are not only increased, while also reducing noise.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of internal structure of hair dryer of the utility model.
Specific embodiment
As shown in Figure 1, a kind of hair dryer of the utility model, including the motor being mounted in casing 1 and is connected to motor
On fan blade, the fan blade includes fan blade disc 2 and air blade 3, and the fan blade disc 2 is equipped with heat release hole 4, face shared by heat release hole 4
Product is the 1/4-1/3 of 2 surface area of fan blade disc, and 4 edge of heat release hole is at least apart from 3 centimetres of 2 outer edge of fan blade disc, the heat release hole
Strengthening rib strip 5 is equipped in 4.The edge shape of 4 edge shape of the heat release hole matching air blade 3.Between the strengthening rib strip 5
Junction is set to 4 edge of heat release hole.The strengthening rib strip 5 has gradient, and inclined direction is consistent with fan blade rotation direction.Institute
5 surface of strengthening rib strip is stated with heat dissipation burr.5 projected area of strengthening rib strip is lower than the 1/10 of 4 projected area of heat release hole.It dissipates
Hot hole 4 is evenly distributed on 2 surface of fan blade disc.
The utility model application method is consistent with conventional hair dryer, and the fan blade disc 2 of the hair dryer of conventional design is equipped with 9
A circular aperture when machine operation, drives air to enter from motor tail portion, by the aperture of motor front end, is led out by fan blade,
Reach a good cooling effect to motor.And circular aperture is changed to the large-scale heat dissipation with strengthening rib strip 5 by the present invention
Hole 4.The utility model improves the effect of heat dissipation through this structure, while also reducing noise.
The casing 1 of hair dryer is slowly to increase at a distance from involute shape, with fan blade, is come when air is thrown out of from fan blade
When, a higher-pressure region between fan blade and casing 1 enables and reaches a biggish air quantity and wind in outlet spout in air
Speed.And the utility model uses biggish heat release hole 4 also to can be further improved the wind-guiding amount upper limit of air blade.
