Specific embodiment
Fig. 1 is specially a kind of gardens hair dryer 100 to gardens blower shown in Fig. 3, comprising: fan 10, motor 11,
Housing unit 12.Wherein, housing unit 12 is formed with the airflow channel 13 extended along first straight line direction, in airflow channel 13
Receiving portion 133, air duct portion 134, inlet section 135 and handle portion 15 are formed on extending direction, fan 10 and the installation of motor 11 are extremely
Receiving portion 133, motor 11 are axis rotation with first axle 101 for driving fan 10, and fan 10 is specially aerofoil fan, air inlet
Portion 135 states the two sides that air duct portion 134 is separately positioned on fan 10, and first straight line is parallel to first axle 101, in the present embodiment
In, first straight line and first axle 101 essentially coincide, and fan 10, which can be generated when rotating from inlet section 135, enters airflow channel
Air blowing air-flow in 13, air duct portion 134 are used for being oriented to the air-flow effluent stream channel 13 after flowing through fan 10, inlet section 135
Enter airflow channel 13 from the external world in guiding air-flow, handle portion 15 is used to hold operation hair dryer 100 for user.
Housing unit 12 is also parallel to 102 almost symmetry of the first symmetrical plane of first straight line about one.Specifically,
Housing unit 12 includes about the symmetrical first shell of symmetrical plane and second shell, and first shell and second shell can be two
A independent part, both can be fixedly connected by screw.First shell and second shell surround when docking and form gas
Circulation road 13.Airflow channel 13 is essentially the cylinder around first straight line, and cylinder is divided into inner wall 131 and outer wall 132, and fan 10 is set
Set the side in motor 11 close to inlet section 135.Air inlet 135b, air inlet are formed in the inlet section of airflow channel 13 135
135b is also equipped with separation net 14, separation net 14 be it is latticed, can cover at least partly air inlet 135b, and by detachably first
Part is connected to air inlet 135b.Separation net 14 enables blowing air-flow to uniformly enter airflow channel 13, and separation net 14 is also
It is avoided that the sundries of larger particles enters in airflow channel 13.
When user's operation hair dryer 100, motor runs at high speed, and fan blade and gas current friction generate high frequency noise, the present embodiment
In, by installing effective absorption of the realization of noise reduction component 16 to above-mentioned high frequency noise in 13 inner wall 131 of airflow channel, just disappear below
The specific structure and its connection type of sound component 16 do specific introduction.
As shown in Fig. 1 to 7, inlet section 135 forms a round table-like through-hole, and internal diameter is along first straight line far from air inlet
The direction 135b is gradually reduced and tends to a preset value.Noise reduction component 16 is fixedly connected with or is detachably connected to inlet section 135
On inner wall 131, it is at least partially disposed between fan 10 and air inlet 135b.Disappear since the special operating condition of hair dryer 100 determines
The service life of sound component 16 is less than the service life of hair dryer 100 itself, therefore using in engineering, it needs periodically to noise reduction component 16
It is replaced.To increase the convenience that noise reduction component 16 is replaced, in the present embodiment, 135 inner wall 131 of inlet section is formed with multiple peaces
The locating piece 135a of noise reduction component 16 is filled, locating piece 135a can be integrally formed or be fixedly attached to inner wall with inner wall 131
