Abstract
The present invention relates to a kind of air pump, it include housing, the motor be arranged in housing.Its middle shell includes support, and the stator of motor hangs and is arranged in the support of housing, and one end of rotor is also provided with fan, and the whole air-flows sucked during fan turns are between stator and support.The present invention adopts stator suspension structures, makes the wind of fan evenly by stator outer surface, thermal source body is dispelled the heat, good heat dissipation effect.
Description
Technical field
The present invention relates to a kind of air pump.
Background technique
Existing air pump, especially small-power air pump, be all take aluminum component as its motor of stent support, the characteristic by metal aluminium rapid heat dissipation cools motor.And when operating ambient temperature is higher, single dependence Steel Support heat radiation is not enough, therefore, also can increases fan blade fan and carry out supplement heat rejecter.
But these two kinds of types of cooling, the cooling effect for motor is not but very desirable, and especially under high-temperature work environment, machine local temperature is very high.
Therefore, truly have needs to provide a kind of air pump, its structure is simple, good cooling results.
Summary of the invention
In order to overcome the shortcoming of existing air pump cooling effect difference, the invention provides a kind of air pump, its structure is simple, good cooling results.
The technical solution adopted for the present invention to solve the technical problems is: a kind of air pump, and it includes housing, the motor be arranged in housing.Its middle shell includes support, support is by fore poppet, back poppet, both are combined into barrel-shaped, the stator of motor hangs and is arranged in the support of housing, and one end of rotor is also provided with fan, the whole air-flows sucked during fan turns are between stator and support, and described air-flow directly sucks from the rear portion of casing, enters the cavity at motor rear portion.The present invention adopts stator suspension structures, makes the wind of fan evenly by stator outer surface, thermal source body is dispelled the heat, good heat dissipation effect.
Its fan is also provided with spiral case outward, forms vortex type air channel to make fan.This is the motor usually adopted due to small-power air pump is induction machine, and its rotating speed is on the low side, can not play the optimum efficiency of fan blade, can have certain influence to the cooling effect of complete machine.And the present invention is not when adjusting motor, is vortex flow formula air channel, makes fan vane be issued to best cooling effectiveness in slow-revving situation by adjusting the air channel of fan, air inlet/outlet is very regular simultaneously, has good cooling effect to overall and local.
Further, in different embodiments, wherein shell holder includes fore poppet, back poppet, and both are combined into tubular, and motor is arranged in the inner.
Further, in different embodiments, the gusset in order to support stator is provided with in its medium-height trestle.
Further, in different embodiments, the diameter of its fan is greater than the external diameter of motor stator.
Further, in different embodiments, wherein timbering material is plastic materials.
Further, in different embodiments, wherein timbering material is nylon material.
Relative to prior art, the invention has the beneficial effects as follows, the present invention adopts stator suspension structures, makes the wind of fan evenly by stator outer surface, thermal source body is dispelled the heat, good heat dissipation effect.Further, arrange vortex flow formula air channel, make fan vane be issued to best cooling effectiveness in slow-revving situation, air inlet/outlet is very regular simultaneously, further strengthens cooling effect that is overall and local.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the schematic perspective view of the air pump that the present invention relates to; With
Fig. 2 is the sectional view of air pump as shown in Figure 1 along medial axis.
Embodiment
Refer to shown in Fig. 1,2, in an embodiment of the invention, which provide a kind of air pump 100, it includes housing, the motor be arranged in housing.Its middle shell includes fore poppet 10, back poppet 12, and both are combined into tubular, and motor is arranged in the inner.And the support of motor uses nylon material (in other embodiments, it also can be adopt other plastic materialss), and this also reduces the cost of product to a certain extent.
The stator 20 of motor hangs and is arranged in the support 10,12 of housing, and is provided with the gusset (not shown) in order to support stator in support.One end of rotor 22 is also provided with fan 30, and the diameter of its fan is greater than the external diameter of motor stator.And fan is also provided with spiral case 40 outward, form vortex type air channel to make fan.Its fan and spiral case coordinate the airflow direction formed, and refer to the direction of arrow in Fig. 2.
The present invention adopts stator suspension structures, and fan is greater than the external diameter of motor stator through diameter, so makes the wind of fan evenly by stator outer surface, thermal source body is dispelled the heat, good heat dissipation effect.
Further, the motor usually adopted due to small-power air pump is induction machine, and its rotating speed is on the low side, can not play the optimum efficiency of fan blade, can have certain influence to the cooling effect of complete machine.And the present invention is not when adjusting motor, be vortex flow formula air channel by adjusting the air channel of fan, make fan vane be issued to best cooling effectiveness in slow-revving situation, air inlet/outlet is very regular simultaneously, further strengthens cooling effect that is overall and local.
