Abstract
The utility model provides an electric air pump which can perform active heat radiation on a motor during working. The electric air pump comprises an air passage shell, fan blades, a motor and a protection shell, wherein the motor is arranged in the protection shell, the protection shell and the air passage shell are mounted together, ventilation holes communicated with interior of the protection shell are arranged on the air passage shell, and air suction holes communicated with outside are arranged in the protection shell; and the ventilation holes, the space in the protection shell and the air suction holes constitute an air suction channel. The electric air pump has simple structure and excellent heat radiation effect, and can be refitted on the basis of the structure of the existing electric air pump and effectively ensure the service life of the electric air pump.
Description
Technical field
The utility model relates to a kind of electronic being used to and inflates device with exhaust.
Background technique
Electric air pump can be used for occasions such as bleeding of the inflation of air mattress and vacuum storing bag usually.Existing electric air pump is by the air channel shell, is arranged on the fan blade in the shell of air channel and is used to drive the motor that fan blade rotates and constitute, and motor is arranged in the containment vessel, and containment vessel is provided with radiation hole.During work, the air sucking mouth of fan blade by the air channel shell sucks the air discharge after air and the exhaust port by the air channel shell will pressurize.Such electric air pump is centrifugal supercharging type gas-filled pump, and higher blast can be provided.But such electric air pump only relies on radiation hole to carry out passive heat radiation usually, and temperature raises very soon during machine operation, is easy to damage in advance because temperature is too high, thereby influences working life of whole electric air pump.So need improve existing electric air pump, to prolong its working life.
Summary of the invention
The purpose of this utility model provides a kind of electric air pump that in the lump motor is carried out active heat radiation when work.
For achieving the above object, the utility model is taked following technological scheme:
Electric air pump comprises air channel shell, fan blade, motor and containment vessel, and motor is arranged in the containment vessel, and containment vessel and air channel shell are installed together, and the air channel shell is provided with the vent hole that communicates with the inside of containment vessel, is provided with on containment vessel and the extraneous wind inlet that communicates; Vent hole, containment vessel volume inside and wind inlet constitute an air-suction channel.
When fan blade rotates,, also can suck air, so can obtain bigger suction air volume from air-suction channel except that sucking the air from the air sucking mouth of air channel shell.The more important thing is that the air of the containment vessel inner space of flowing through can be taken away the heat of motor and inject article to be inflated,, also can not burn, effectively guaranteed the working life of motor because temperature is too high even make that motor works long hours.
In the utility model, fan blade can formal dress or anti-dress; And fan blade towards being left-hand or dextrad.More air sucks from the air sucking mouth during fan blade formal dress; Fan blade is anti-when adorning, and more air sucks from air-suction channel.
In addition, can have pore on the round plate of fan blade, can alleviate on the one hand the weight of fan blade, still can upwards distribute at the quit work heat of rear motor of motor on the other hand, to reduce the temperature of motor as early as possible by pore.
The utility model is simple in structure, and radiating effect is good, can convert on the structure of existing electric air pump, has effectively guaranteed the working life of electric air pump.

Embodiment
Below in conjunction with drawings and Examples the utility model content is described further.
Embodiment 1
As shown in Figure 1 and Figure 2, electric air pump comprises air channel shell 1, fan blade 2, motor 3 and containment vessel 4.
Wherein, air channel shell 1 is made of upper air duct shell 5, lower air duct shell 6.The top of upper air duct shell 5 is provided with air sucking mouth 7; The bottom of lower air duct shell 6 is provided with some vent holes 8; After upper air duct shell 5 and 6 amalgamations together of lower air duct shell, can form the exhaust port 9 of air channel shell 1.Fan blade 2 is arranged in the space between upper air duct shell 5 and the lower air duct shell 6.
The rotating shaft of motor 3 is passed lower air duct shell 6 and is linked together with fan blade 2, can drive fan blade 2 and rotate.Motor 3 is among the encirclement of containment vessel 4 simultaneously.
As shown in Figure 1, the fan blade 2 of present embodiment is in the position of anti-dress, so the electric air pump more air sucks from air-suction channel.The fan blade 2 of this enforcement is a dextrad, on the round plate of fan blade 2, also is evenly distributed with pore 11, is used for the heat radiation after motor 3 stalls.
As shown in Figure 1 and Figure 2, also be provided with power switch 12 and power line cable-through hole 13 on the containment vessel 4 of present embodiment.
Present embodiment and embodiment's 1 difference is: as shown in Figure 4, fan blade 2 ' is in the position of formal dress, and fan blade 2 ' is a left-hand.
What this specification was enumerated is better embodiment of the present utility model only, and all equivalent technologies conversion of being done under working principle of the present utility model and thinking all are considered as protection domain of the present utility model.
