Abstract
The invention discloses a low-resistance air blower which comprises an air blower body, wherein the air blower body is provided with an air outlet; a ring-shaped air inlet is also formed in the air blower body; the ring-shaped air inlet clings to the air outlet; a drive motor is arranged in the ring-shaped air inlet; a tubular fan is arranged at the periphery of the drive motor; the drive motor is an asynchronous alternating current (AC) motor; the tubular fan is made of metal. According to the low-resistance air blower, the ring-shaped air inlet is formed in the air blower body at the position close to the air outlet, the drive motor and the tubular fan are arranged in the air inlet, and the position of the fan is close to the air outlet, so that the airflow rapidly reaches the air outlet and flows out of the air blower when being generated by the rotation of the fan, the space resistance of the fan is greatly reduced, the rotating speed of the fan is increased, and the working efficiency of the air blower is improved.
Description
Technical field
The present invention relates to a kind of blower, or rather, is a kind of lower resistance blower.
Background technique
Blower is primarily of following six part compositions: motor, air filter, blower body, air chamber, base (fuel tank of holding concurrently), oil dripping mouth.Blower by rotor eccentricity biased in cylinder running, and makes the volume-variation between the blade in rotor by air intake, compresses, spues.Lubrication is delivered to oil dripping mouth by the on-stream pressure difference of blower that utilizes automatically, and to reduce friction and noise in instillation cylinder, cylinder charge can be kept not reflux, this type of blower is also called sliding vane blower simultaneously.
The blower generally used at present due to wind inlet and exhaust outlet distant, the air flowed needs certain distance to arrive exhaust outlet, and the resistance that blower flabellum is subject to is larger.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus the lower resistance blower that the resistance providing a kind of flabellum to be subject to is less.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of lower resistance blower, comprise a blower body, described blower body is provided with an exhaust outlet, described blower body is also provided with a ring-type suction port, described ring-type suction port is near described exhaust outlet, in described ring-type suction port, be provided with a drive motor, be arranged with a tubular fan at the outer of described drive motor.
As preferred embodiment of the present invention, described drive motor is asynchronous AC motor.
As preferred embodiment of the present invention, described tubular fan is made of metal.
Because the position of lower resistance blower of the present invention near exhaust outlet on blower body is provided with ring-type suction port, and in suction port, be provided with drive motor and tubular fan, position of fan is near exhaust outlet, when fan rotates generation air-flow time, air-flow can arrive exhaust outlet very soon and flow out blower, thus substantially reduce the space resistance that fan is subject to, improve the rotating speed of fan, improve the working efficiency of blower.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of lower resistance blower of the present invention;
Fig. 2 is the perspective view of the lower resistance blower in Fig. 1, is now another visual angle.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The invention provides the lower resistance blower that resistance that a kind of flabellum is subject to is less.
As shown in Figure 1 and Figure 2, a kind of lower resistance blower 1, comprise a blower body 21, described blower body 21 is provided with an exhaust outlet 22, described blower body 21 is also provided with a ring-type suction port 3, described ring-type suction port 3, near described exhaust outlet 22, is provided with a drive motor 4 in described ring-type suction port 3, is arranged with a tubular fan 5 at the outer of described drive motor 4.
As shown in Figure 1 and Figure 2, described drive motor 4 is asynchronous AC motor.
As shown in Figure 1 and Figure 2, described tubular fan 5 is made of metal.
The position of lower resistance blower near exhaust outlet on blower body of this invention is provided with ring-type suction port, and in suction port, be provided with drive motor and tubular fan, position of fan is near exhaust outlet, when fan rotates generation air-flow time, air-flow can arrive exhaust outlet very soon and flow out blower, thus substantially reduce the space resistance that fan is subject to, improve the rotating speed of fan, improve the working efficiency of blower.
Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more function module simultaneously, thus expands its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
