Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
The present invention provides a kind of hair dryer, which is used to clear up lawn, the weeds in garden.Institute as shown in Figure 1 to Figure 4
Show, which includes casing 1, Blowing drum 2, air intake cover 3, motor 4 and fan component 5, and fan component 5 includes the first fan 51
With the second fan 52.Casing 1 can be integrally formed, and can also be spliced by multiple portions, in the present embodiment, in order to reduce
The assembling difficulty of 1 inner body of casing, as shown in Fig. 2, casing 1 is set as being spliced to form by two parts.Specifically, casing
1 includes the first shell 11 and second shell 12 of left and right arrangement, and first shell 11 is right shell body, and second shell 12 is left shell,
First shell 11 and second shell 12 are preferably formed using plastic injection.Certainly in other embodiments, casing 1 can also be by upper
The upper housing and lower case of lower arrangement are spliced, and are either spliced by three parts, four parts or more parts.The
One shell 11 and second shell 12 are detachably connected, and the mode being detachably connected, which can choose, to be snapped connection or connected using screw
It connects.Clean-up task is carried out for the ease of user's hand-held hair dryer, the top of casing 1 is provided with handle 13.Handle 13 and casing 1 can
To be structure as a whole, i.e., when manufacturing casing 1, directly process to form handle 13 at the top of casing 1, or handle is fabricated separately
After 13, then handle 13 is fixed on casing 1, in the present embodiment, in order to simplify the assembling procedure of hair dryer, preferred grip 13
It is integrally formed with casing 1.
As shown in figure 3, casing 1 is open at one end, and forms the accommodating chamber for accommodating air intake cover 3, one end of Blowing drum 2 is placed in
In accommodating chamber, the prominent casing 1 of the other end is arranged.The split ring of air intake cover 3 around Blowing drum 2 outer wall, the air inlet of air intake cover 3
Opening direction is identical as the opening direction of the air outlet of Blowing drum 2, and the air inlet of Blowing drum 2 protrudes into air intake cover 3.4, motor
It inside air intake cover 3, and is fixedly mounted on the bottom surface of air intake cover 3, and the motor shaft of motor 4 is set along the outflow direction of air-flow
It sets, motor shaft is connect with the first fan 51, and air inlet one end in Blowing drum 2 is arranged in the first fan 51, to be conducive to mention
High fan allows the flow to accurately flow out at a high speed via Blowing drum 2 to the guiding function of air-flow.In the driving effect of motor 4
Under, the rotation of the first fan 51 forms main high-speed flow to accelerate the air-flow after the bottom surface of air intake cover 3 is reversed, air-flow
Accelerate to form a negative pressure space in the bottom end of air intake cover 3 suddenly, since the air pressure of the bottom end two sides of air intake cover 3 is different,
Hair dryer can be given to apply an active force, and the action direction of the active force and main high-speed flow are to the reaction force of hair dryer
It is contrary, so as to balance out a part of even all of air-flow to the reaction force of hair dryer, and then be conducive to drop
Low hair dryer holds the difficulty of blower operations to the reaction force of user and user, improves the usage experience of user.
Further, as shown in figure 4, setting the bottom surface of air intake cover 3 to make the bottom end of air intake cover 3 that there is catchment effect
It is set to cone structure.As shown in figure 3, flow level enters the bottom end of arrival air intake cover 3 after air intake cover 3, due to the bottom of air intake cover 3
End is cone structure, and air-flow is changed to inclined direction while reversed, by horizontal direction, and concentrates to the direction of Blowing drum 2
Inclination enters in Blowing drum 2 so that main high-speed flow be made to concentrate, further increases the vacuum effect of the bottom end of air intake cover 3, drops
Low active force of the hair dryer to user.
Further, secondary channels 6 are additionally provided in casing 1, secondary channels 6 specifically include air intake passage 61 and air-out passage
62, air intake passage 61 is formed by the space between the inner wall of accommodating chamber and the outer wall of air intake cover 3, one end of air-out passage 62 with into
Wind channel 61 is connected to, and the other end extends to the rear of casing 1, and towards the bottom angled of casing 1.The air outlet of air-out passage 62
The opening direction of the air outlet of air-out direction and Blowing drum 2 is on the contrary, and the angle between air-out passage 62 and horizontal direction is sharp
Angle.
The connectivity part of air intake passage 61 and air-out passage 62 is arranged in second fan 52, and the size of the second fan 52 is less than
The size of one fan 51.After air-flow is out of air intake passage 61 entrance casing 1, auxiliary high speed gas is formed after the acceleration of the second fan 52
Stream, auxiliary high-speed flow flow to the direction opposite with main high-speed flow, effect of the auxiliary high-speed flow to casing 1 by air-out passage 62
Power component in the horizontal direction can directly balance out the main high-speed flow in part to the reaction force of hair dryer, auxiliary high-speed flow pair
The active force of casing 1 vertical direction component can partial offset fall the gravity of hair dryer, to further reduced blowing
Machine holds the difficulty of blower operations to the reaction force of user and user, improves the usage experience of user.
The auxiliary high-speed flow that the main high-speed flow and the second fan 52 generated due to the first fan 51 is generated can be to handle
Hand 13 forms the overturning arm of force, and main high-speed flow is flipped up hair dryer, and auxiliary high-speed flow downwardly turns over hair dryer, in order to keep away
When exempting from user's hand-held hair dryer operation, hair dryer is overturn upwards, and the arm of force for preferably generating auxiliary high-speed flow is greater than main high speed
The arm of force that air-flow generates.
Further, in order to improve the throughput in secondary channels 6, as shown in figure 4, being additionally provided with ventilation opening on casing 1
14, ventilation opening 14 is connected to air intake passage 61.14 quantity of ventilation opening is preferably several, such as two, three or four.In order to
Realize uniform air inlet, ventilation opening 14 is arranged circumferentially along casing 1.The increase of 6 interior air-flow amount of secondary channels can further increase
Greatly to the overturning arm of force of handle 13, hair dryer is further prevented to overturn.
In the present embodiment, the second fan 52 is equally driven by motor 4, in order to simplify hair dryer internal structure, preferably
Two fans 52 and the first fan 51 are driven using the same motor 4, and motor 4 preferably uses inner rotor motor, the motor shaft of motor 4
The prominent casing 1 in both ends is arranged, and the bottom surface that one end of motor shaft passes through air intake cover 3 is connect with the second fan 52, the other end and the
The connection of one fan 51.
Obviously, the above embodiment of the present invention is just for the sake of clearly illustrating examples made by the present invention, and being not is pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
Made any modifications, equivalent replacements, and improvements etc., should be included in the claims in the present invention within the spirit and principle of invention
Protection scope within.
