Detailed Description
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
Embodiment one:
the embodiment discloses an electric hair dryer. As shown in fig. 1, the electric hair dryer comprises a handle 1 and an air duct 2 which are communicated with each other, an inner cavity pipe 6 is sleeved on the inner side of the air duct 2, and an annular rear baffle 7 is connected between the air inlet side end part of the air duct 2 and the outer end part of the air inlet section of the inner cavity pipe 6. An air inlet hole 62 is formed in the side wall, close to the air inlet, of the inner cavity pipe 6, and air flows sequentially pass through the air inlet of the inner cavity pipe 6 and the air inlet hole 62 and then enter the electric blower.
As shown in fig. 2 and 3, a fan blade 3 and a heating wire 9 are sequentially arranged in the air duct 2 along the blowing direction, the fan blade 3 is an annular fan blade with a bearing 5 penetrating through the middle part, and an inner cavity pipe 6 penetrates through the middle part of the bearing 5; a motor 4 is arranged in the handle 1. A motor bevel gear 41 is arranged at the output end of the motor 4, a fan blade bevel gear 31 meshed with the motor bevel gear 41 is arranged on the fan blade 3, and the axis of the motor bevel gear 41 is perpendicular to the axis of the fan blade bevel gear 31 or forms a certain included angle. The motor drives the motor bevel gear 41 to rotate around the axis, and the motor bevel gear 41 drives the fan blade bevel gear 31 to rotate around the axis of the motor bevel gear, so that the fan blades 3 are driven to rotate, and blowing air is generated and blown out from the air outlet channel 21 between the inner cavity pipe 6 and the air duct 2.
In the embodiment, the motor 4 is arranged in the handle 1, the motor 4 does not generate moment at the handle 1 any more, the handle 1 is better in hand feeling and more labor-saving when being gripped, and the blowing direction is easy to control; the motor 4 is connected with the fan blades 3 through a pair of bevel gears which are meshed with each other, so that the movement direction is changed, the motor 4 in the handle 1 can drive the fan blades 3 in the air duct 2, and the structure is reasonable and compact; the ring fan blade has strong blowing capability, large air quantity and high air speed, thereby improving the power efficiency of the electric blower.
In order to make the ventilation smoother, the air inlet 62 is located on the windward side of the fan blade 3, and the solid line with arrow in fig. 2 is the ventilation path of the ventilation air.
The side wall of the air duct 2, the side wall of the air inlet section of the inner cavity pipe 6 and the rear baffle 7 are enclosed into a concave structure with a C-shaped section, and a PCB 8 (PCB, printed Circuit Board, printed circuit board) is arranged in the concave structure. The dashed line with arrows in fig. 2 shows the flow path of part of the air after the air inlet hits the inner wall of the air duct 2 at the air inlet 62, and part of the air is flushed into the recess structure, blown through the PCB board 8, and returned to the air inlet 62 after hitting the inside of the recess structure, and mixed into the subsequent air. The heat on the PCB 8 can be taken away when the air flow blows through the PCB 8, so that the PCB 8 is cooled.
In view of the fact that it is difficult to make all the air intake enter the air outlet channel 21 only by the arrangement of the air intake holes 62, the electric blower of the embodiment is vertically provided with the wind shielding plate 61 in the inner cavity tube 6, and the side edge of the wind shielding plate 61 is completely attached to the inner wall of the inner cavity tube 6, so that the inner cavity tube 6 is divided into an air intake section and an air outlet section. The air inlet hole 62 is formed in the side wall of the air inlet section, and the area of the air inlet hole 62 is increased as much as possible without cutting off the inner cavity tube 6. The air flow can enter the air outlet channel 21 from the port outside the air inlet section of the inner cavity pipe 6 through the air inlet hole 62, and no air flow directly rushes to the port of the air outlet channel 21 from the inner cavity pipe 6.
The specific shape and material of the wind shielding sheet 61 are not limited, and a wind shielding effect may be achieved. Preferably, the wind shielding sheet 61 is made of transparent material, and forms the feeling that the central axis part of the electric hair dryer is completely opened, and has attractive appearance and strong technological feeling.
In order to reduce the force applied by the motor bevel gear 41 to the output shaft of the motor 4 as much as possible, the motor 4 is arranged at the upper part of the inner side of the handle 1, so that the length of the output shaft of the motor 4 is shortened, and the torque of the reaction force generated when the motor bevel gear 41 is meshed with the fan blade bevel gear 31 at the root part of the output shaft of the motor 4 is reduced.
As shown in fig. 4, the annular fan blade includes an inner ring body 32 and an outer ring body 33 which are sleeved, a plurality of blades 34 are obliquely arranged between the inner ring body 32 and the outer ring body 33, a certain distance is reserved between two adjacent blades 34, and air flow passes through the space between two adjacent blades 34. The bevel blade gear 31 may be disposed on the side of the inner ring body 32 or on the side of the outer ring body 33, and preferably, the bevel blade gear 31 is disposed on the side of the inner ring body 32, and the overall volume is smaller.
Embodiment two:
the present embodiment discloses an electric hair dryer having substantially the same structure as the first embodiment. The difference is that: as shown in fig. 5, a worm 45 is disposed at the output end of the motor 4, a worm wheel 35 meshed with the worm 45 is disposed on the fan blade 3, and the axis of the worm is perpendicular to the axis of the worm wheel or forms a certain included angle. The motor 4 drives the worm 45 to rotate around the vertical axis, and the worm 45 drives the worm wheel 35 to rotate around the horizontal axis, so that the same movement effect as in the first embodiment is realized.
The teeth of the worm wheel 35 may be provided on the outer wall (as shown in fig. 5 a) or on the side wall (as shown in fig. 5 b) of the fan blade 3, without affecting the engagement with the worm, only by changing the mounting position of the worm 45 accordingly.
Embodiment III:
the present embodiment discloses an electric hair dryer having substantially the same structure as the first embodiment. The difference is that: the direction conversion part comprises a motor universal joint and a fan blade universal joint which are connected through a cross connecting piece which is obliquely arranged, the motor universal joint is arranged at the output end of the motor, and the fan blade universal joint is arranged on the rotating shaft of the fan blade.
The output end of the motor rotates around a vertical line, so as to drive the motor universal joint to rotate in the same direction; the motor universal joint drives the fan blade universal joint to rotate around the horizontal line or the axis close to the horizontal direction through the cross connecting piece, and then drives the fan blade to rotate around the horizontal line or the axis close to the horizontal direction, so that the same movement effect of driving the fan blade to rotate is achieved as in the first embodiment.
