Abstract
The utility model relates to an air pump, which comprises a shell and a motor arranged in the shell, wherein the shell comprises a support; a stator of the motor is arranged in the support of the shell, and a fan is arranged at one end of a rotor. The air pump adopts a stator suspension structure, and the wind of the fan goes through the outer surface of the stator evenly so that a heat source body can realize heat dissipation, thereby having good heat dissipation effect.
Description
Technical field
The utility model relates to a kind of air pump.
Background technique
Existing air pump, especially small-power air pump all are to be its motor of stent support with the aluminum component, by the characteristic of metal aluminium rapid heat dissipation motor are cooled off.And work as operating ambient temperature than under the condition with higher, single dependence Steel Support heat radiation is not enough, therefore, also can increase the fan blade fan and assist cooling.
But these two kinds of types of cooling but are not very desirable for the cooling effect of motor, and especially under high-temperature work environment, the machine local temperature is very high.
Therefore, truly having to provide a kind of air pump, and it is simple in structure, good cooling results.
The model utility content
In order to overcome the shortcoming of existing air pump cooling effect difference, the utility model provides a kind of air pump, and it is simple in structure, good cooling results.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of air pump, it includes housing, is arranged at the motor in the housing.Its middle shell includes support, and the stator of motor hangs and is arranged in the support of housing, and an end of rotor also is provided with fan.The utility model adopts the stator suspension structures, makes the wind of fan evenly pass through stator outer surface, makes the thermal source body obtain heat radiation, good heat dissipation effect.
Further, in different mode of executions, wherein fan also is provided with spiral case outward, so that fan forms the vortex type air channel.This is that its rotating speed is on the low side, can not bring into play the optimum efficiency of fan blade, can certain influence be arranged to the cooling effect of complete machine because the motor that the small-power air pump adopts usually is an induction machine.And the utility model is under the situation of not adjusting motor, air channel by the adjustment fan is vortex flow formula air channel, make the fan fan blade be issued to best cooling effectiveness in slow-revving situation, it is very regular to pass in and out wind simultaneously, and integral body and part are all had good cooling effect.
Further, in different mode of executions, wherein shell holder includes fore poppet, back poppet, and both are combined into tubular, and motor is arranged in it.
Further, in different mode of executions, be provided with gusset in its medium-height trestle in order to support stator.
Further, in different mode of executions, wherein the diameter of fan is greater than the external diameter of motor stator.
Further, in different mode of executions, wherein timbering material is a plastic materials.
Further, in different mode of executions, wherein timbering material is a nylon material.
With respect to prior art, the beneficial effects of the utility model are that the utility model adopts the stator suspension structures, makes the wind of fan evenly pass through stator outer surface, makes the thermal source body obtain heat radiation, good heat dissipation effect.Further, vortex flow formula air channel is set, makes the fan fan blade be issued to best cooling effectiveness in slow-revving situation, it is very regular to pass in and out wind simultaneously, has further strengthened whole and local cooling effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the schematic perspective view of the air pump that relates to of the utility model; With
Fig. 2 is that as shown in Figure 1 air pump is along the sectional view of medial axis.
Embodiment
See also shown in Fig. 1,2, in a mode of execution of the present utility model, it provides a kind of air pump 100, and it includes housing, is arranged at the motor in the housing.Its middle shell includes fore poppet 10, back poppet 12, and both are combined into tubular, and motor is arranged in it.And the support of motor uses nylon material (in other embodiments, it also can be to adopt other plastic materialss), and this has also reduced 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 the support.One end of rotor 22 also is provided with fan 30, and wherein the diameter of fan is greater than the external diameter of motor stator.And fan also is provided with spiral case 40 outward, so that fan forms the vortex type air channel.Wherein fan and spiral case cooperate formed airflow direction, see also the direction of arrow among Fig. 2.
The utility model adopts the stator suspension structures, and fan is through the external diameter of diameter greater than motor stator, so makes the wind of fan evenly by stator outer surface, makes the thermal source body obtain heat radiation, good heat dissipation effect.
Further, because the motor that the small-power air pump adopts usually is an induction machine, its rotating speed is on the low side, can not bring into play the optimum efficiency of fan blade, can certain influence be arranged to the cooling effect of complete machine.And the utility model is under the situation of not adjusting motor, air channel by the adjustment fan is vortex flow formula air channel, make the fan fan blade be issued to best cooling effectiveness in slow-revving situation, it is very regular to pass in and out wind simultaneously, has further strengthened whole and local cooling effect.
