Movable part or air flow regulator is utilized to control the air-flow by described second gas channel and described first gas channel, to allow the air themperature of mass flowing nozzle almost immediately to become room temperature from hot.Furthermore, it is possible to utilize the balance adjustment gas flow temperature regulating each interchannel air-flow.For example, it is possible to described movable part is arranged on centre position, open at the entrance of the first gas channel described in this centre position and the entrance of described second gas channel.
In fig. 1 and 2, at described air outlet slit place, before described second gas channel terminates in described first gas channel.In this way, it does not have extend to the heater block beyond described cooling-part, thus the injury of user being preferably minimized.
Suitable control device can be utilized to start described movable part.What the power that can be applied by user or electric system were applied drives the Li Shi mechanism work of described fan unit.
Operation principle structure: impeller is the parts by rotating the air-flow being created towards axially front centered by axis of blowing.Impeller is configured in cylindrical portion.As shown in Figure 1 and Figure 2, the impeller of present embodiment has centrally located cup portion and is radially oriented, from cup portion, multiple blades that outside extends.Cup portion is fixed on the axle of motor.Multiple blades circumferentially arrange at the radial outside of cup portion.Each blade is relative to axial and peripheral, oblique extension.Using in circumference two ora terminalis of each blade by the ora terminalis on front side of direction of rotation as the first ora terminalis.Further, using in two ora terminalis of the circumference of each blade by the ora terminalis on rear side of direction of rotation as the second ora terminalis.In this impeller, the second ora terminalis is positioned at the position leaning on axially front than the first ora terminalis.Therefore, when the impeller is rotated, the wind from the axial rearward direction of impeller towards the axially front of impeller is produced.Further, the impeller of present embodiment is the single resin component obtained by injection mo(u)lding.But, impeller also can be made up of multiple parts.Such as, cup portion and multiple blades may also be the parts of split.Further, impeller 20 may also be and formed by material in addition to the resins.
Motor for providing the mechanism for the power rotated to impeller.In the present embodiment, the position of axially front is being leaned on to be configured with motor than impeller.But, motor can also be configured in the position leaning on axial rearward direction than impeller.Motor has the axle extended along air-supply axis.If driving motor, then the magnetic force that can pass through to be configured between the coil in motor and Magnet produces the torque centered by axis of blowing.Thus, the axle of motor rotates centered by axis of blowing.
In the present embodiment, motor uses Brushless DC motor.Owing to Brushless DC motor will not produce the performance degradation that causes because of the abrasion of brush, thus the life-span is longer than the life-span of brush motor.Further, Brushless DC motor speed change easier than alternating current motor, and it is easily reduced power consumption.However, it is possible to use brush motor or alternating current motor to replace Brushless DC motor.
Rectification part is arranged in the ratio impeller in cylindrical portion by axially front and the position leaning on axial rearward direction than heater support.Rectification part has the multiple stator blades extended in a generally radial direction.Multiple stator blades are circumferentially arranging by the position of radial outside than motor.The wind produced by impeller is from process between multiple stator blades, and transmits towards heater support side.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
