Description
Technical field
The utility model relates to garden instrument field, particularly relates to a kind of garden instrument class hand blower alternating current machine preposition structure.
Background technology
Garden instrument class hand blower all adopts centrifugal fan mostly, in recent years, market has occurred axial-flow type hair-dryer.Because centrifugal blower compared by axial-flow type hair-dryer, there is high efficiency, the advantage of Wind Volume, deeply like by consumer.
Air channel feature because of axial-flow type hair-dryer: one, for ensureing integrality and the fluency in air channel, motor is all placed in duct by axial-flow blower on the market; Two, in order to ensure the heat radiation of motor.So the brushless direct-current small machine that the equal efficiency of selection of product is on the market very high, the motor feels hot that amount is little for this kind, do work many (axial-flow blower as Pellenc, EGO brand), but price is very expensive, and be limited to the continuation of the journey of power brick, and the operating time is short.
Utility model content
For solving the problems of the technologies described above, the utility model provides one by AC motor application in axial-flow blower, to increase work efficiency, and reduces the axial-flow blower motor preposition structure of production cost.
The technical scheme that the utility model adopts is: provide a kind of axial-flow blower motor preposition structure, comprise: collecting cover and discharge pipe, described discharge pipe is connected with collecting cover one end, described collecting cover and discharge pipe inside are provided with motor, fan blade and rear deflection cone successively along air-out direction, described motor is alternating current machine, it is fixed in collecting cover, and described fan blade is located at the output of motor, and the collecting cover between described motor output end and fan blade arrival end is closing-in structure.
In the utility model preferred embodiment, the motor that described motor is fixed on collecting cover inside is fixed on muscle position.
In the utility model preferred embodiment, described closing-in structure is taper closing-in structure.
In the utility model preferred embodiment, around the rear deflection cone on rear side of fan blade, be provided with duct.
The beneficial effects of the utility model are: the utility model adopts common alternating current machine, reduces costs, and consider common alternating current machine heat dissipation problem simultaneously, by preposition for common alternating current machine, efficiently solve the heat dissipation problem of alternating current machine.And devise novel collecting cover structure, ensure that air intake is smooth, improve the air channel efficiency of hair-dryer.AC motor application in hand-held axial-flow hair-dryer, is greatly reduced the cost of axial-flow blower, and the operating time of hair-dryer is extended greatly, can manufacture more powerful hair-dryer by success.

Embodiment
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-Fig. 3, the utility model embodiment comprises:
A kind of axial-flow blower motor preposition structure, comprising: collecting cover 1 and discharge pipe 6, described discharge pipe 6 is connected with collecting cover 1 one end.
Described collecting cover 1 is provided with motor 2, fan blade 3 and rear deflection cone 5 with discharge pipe 6 inside successively along air-out direction, and described motor 2 is alternating current machine, and its motor being fixed on collecting cover 1 inside is fixed on muscle position, and is screwed.
The utility model adopts common alternating current machine, reduces costs, and considers common alternating current machine heat dissipation problem simultaneously, by preposition for common alternating current machine, efficiently solves the heat dissipation problem of alternating current machine.The motor that specification can be used less loads larger load, can greatly reduce complete machine cost.
Described fan blade is located at the output of motor 2, is provided with duct 4 around the rear deflection cone 5 on rear side of fan blade 3.
Collecting cover 1 between described motor 2 output and fan blade arrival end is closing-in structure 7.In the present embodiment, described closing-in structure 7 is taper closing-in structure, as shown in Figure 1.
The collecting cover 1 at motor 2 fixed position place is strengthened simultaneously, add the taper closing-in structure 7 at fan blade 2 soon entrance, coordinate the taper of motor lower carriage part to shrink, guarantee that whole air channel has abundant air intake, air intake can not be blocked because of motor preposition, greatly improve air channel efficiency.Efficiently solve the heat radiation and air channel fluency problem that exchange hair-dryer, compare and the axial-flow blower using brshless DC motor, cost is lower, without battery durable problem.
The utility model collecting cover is compared with the collecting cover of prior art, and concrete data are as shown in the table:
| Type | Blade rotational speed (r/min) | Shaft power (W) | Rate of discharge (g/s) | Average exit speed (m/s) | Total head (Pa) | Moment of torsion (Nm) | Efficiency |
| Existing collecting cover | 21500 | 713.3 | 224.53 | 55.55 | 1890.9 | 0.3168 | 48.59% |
| The utility model collecting cover | 21500 | 713.3 | 239.69 | 59.15 | 2143.9 | 0.3184 | 58.51% |
As can be seen from the table, compared with existing collecting cover, when identical blade rotational speed and shaft power, collecting cover of the present utility model can obtain larger rate of discharge and muzzle velocity faster, thus obtains higher operating efficiency.
The beneficial effects of the utility model are: adopt common alternating current machine, reduce costs, and consider common alternating current machine heat dissipation problem simultaneously, by preposition for common alternating current machine, efficiently solve the heat dissipation problem of alternating current machine.And devise novel collecting cover structure, ensure that air intake is smooth, improve the air channel efficiency of hair-dryer.AC motor application in hand-held axial-flow hair-dryer, is greatly reduced the cost of axial-flow blower, and the operating time of hair-dryer is extended greatly, can manufacture more powerful hair-dryer by success.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
