The specific embodiment

In order to better understand technology contents of the present utility model, especially exemplified by the specific embodiment and coordinate appended illustrate as follows.

Please refer to Fig. 1 to Fig. 3, hand blower 10 as the utility model embodiment, comprise: housing 11, be installed on handle 12 and power brick 13 on housing, housing 11 has the blowing portion 111 of extending along housing 11 longitudinal axes L that is connected in one end, be connected in the inlet section 112 of the other end, and be contained in motor (not shown) in housing and by motor-driven fan (not shown), in the present embodiment, fan is aerofoil fan, its central axis line parallel is in the longitudinal axes L of housing, the inlet section 112 of housing forms a ramp shaped, be arranged so that like this incoming air area is larger, be provided with on the slope the rail shape structure that is beneficial to wind-guiding, when fan work, air-flow mainly enters fan along the direction that is parallel to housing longitudinal axes L by inlet section 112, under the effect of fan, flow to vertically blowing portion 111.

Power brick 13 has the shape of general square shape, this shape is extended along direction in space X, Y and the Z of quadrature, therefore, this power brick has length axes A, width axis B and depth axis C, corresponding, along length axes A directional structure vectorical structure length, this length is greater than along the width of width axis B direction, and in the present embodiment, width is also greater than the degree of depth of extending along depth axis C

Handle 12 has a mid-plane P1 who is parallel to housing longitudinal axes L location, grip part 120 on handle 12 is distributed in the both sides of above-mentioned plane P 1, preferably grip part 120 symmetries are distributed in to mid-plane P1 both sides, in order to reduce the length of complete machine, improve the comfortableness of operation simultaneously, power brick 13 is arranged at the top of inlet section 112, and along the direction of length axes A, be distributed in the both sides of mid-plane P1, preferably symmetrical both sides that are distributed in mid-plane P1 alongst.In the present embodiment, power brick 13 is arranged at the rear of handle 12, also can be according to factors such as assembled machine balances power brick 13 need to be arranged on to the place ahead of handle 12.

Power brick 13 has two the first sides 131, described the first side 131 is parallel to width axis B and depth axis C place plane, along X-Y plane direction extension and parallel with mid-plane P1, two the second sides 132 of power brick are parallel to the plane at length axes A and depth axis C place, along Y-Z in-plane extension and vertical with mid-plane P1, distance between two the first sides is greater than two distances between the second side, power brick also has end face 133 and the bottom surface 134 arranging towards work ground P2, described end face 133 and bottom surface 134 are parallel to by the plane at length axes A and width axis B place, along X-Z in-plane, extend.Be understandable that, also can the second side 132 of power brick 13 need to be arranged to towards work ground P2 according to overall design here.

In power brick 13, be provided with rechargeable battery unit, as nickel-cadmium cell, nickel metal hydride battery, lithium ion battery, lithium polymer battery, lithium titanium battery or similar battery unit, use used battery unit that the power brick voltage needing is provided by corresponding electric connection mode.In order to make instrument there is higher flexible applicability, the power brick 13 being installed on housing is dismountable, and in power brick 13, be provided for forming with housing the slide rail (not shown) being slidably connected, certainly, on housing, must be provided with the slide construction coordinating with slide rail, this is apparent, does not repeat herein.Be understandable that, for by battery pack locking on the permanent position of housing, can adopt buckle structure well known to those skilled in the art lock and discharge.

Please refer again to Fig. 1 to Fig. 3, handle 12 extends towards housing 11 rear portions along housing longitudinal axes L, it is plug-in mounting angle that power brick 13 be take the formed less angle of mid-plane P1 of its length axes A and handle, as a kind of preferred version, for in the rear raising operability of plug-in mounting power brick 13, the angle value scope of plug-in mounting angle is: be greater than 60 degree and be less than 90 degree, as a kind of optimum way, power brick 13 is inserted perpendicular to the direction of the mid-plane P1 of handle with its length axes A.

In the present embodiment, in order to improve the balance of complete machine, the center of gravity G of hair-dryer integral body is positioned on the mid-plane P1 of above-mentioned handle 12, this plane P 1 is vertical with the ground P2 of work, motor, fan, blowing portion 111, inlet section 112 are roughly located along the same line, and above-described work ground P2 is defined as a horizontal plane.Make like this compact integral structure, near centroidal distance grip part, reduced and in use overcome the power that hand blower deflection needs, increase hand-held comfort level, reduce hand-held sense of fatigue in long-time use procedure.

Although the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Under the utility model, in technical field, have and conventionally know the knowledgeable, within not departing from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection domain of the present utility model is when being as the criterion depending on claims person of defining.
