Abstract
The invention discloses a motor cover of a hovership type dust collector, comprising a motor and a motor cover for holding the motor, wherein the motor cover consists of a motor cover front cover and a motor cover rear shell, and the side of the motor cover rear shell is provided with an exhaust passage; the motor cover of the hovership type dust collector also comprises a fixed block fixed at the tail part of the motor cover rear shell; and the fixed block is arranged in a supporting frame. With the motor cover structure provided by the invention, part of vibration generated by the motor can be offset by effectively utilizing the reacting force generated by exhaust; meanwhile, reacting force generated by downwards exhausted gas enables the fixed block to move upwards in the supporting frame to generate a gas suspension effect, thus the vibration of the dust collector is effectively reduced, and noise caused by the vibration is reduced.
Description
Technical field
The present invention relates to a kind of dust catcher; The fixed structure that particularly relates to a kind of motor cavity.
Background technology
Usually, vacuum cleaner is to utilize vacuum to produce suction to suck air, makes air flow through various filters, airborne foreign matter is filtered the device in the cleaning chamber.
In general, vacuum cleaner mainly comprises aspirator and suction line, with motor and blower fan is that the aspirator that dominant shape becomes is arranged in the body, suction line comprises suction nozzle and air intake duct, and the air entry of the oriented under shed of suction nozzle and telescoping tube and flexible pipe by air intake duct communicate with the air inlet of body inner blower.During the dust catcher running, the impeller high speed rotating of motor drives blower fan discharges the air in the dust catcher, forms instantaneous vacuum in dust catcher, and forms a quite high Negative Pressure Difference between the ambient atmosphere.Under the effect of this Negative Pressure Difference, near the dust the suction nozzle sucks in the dust bucket in the body by air entry together with air.The air that contains dust after filtering, flows back to the dust catcher outside from air outlet again in the body dust bucket.Like this, just reach the effect of dust out, clean floor.The suction rate of vacuum cleaner is divided into a plurality of class of operating control, adapts to the scope of operation of different cleaning objects such as ground, bed surface, sofa, corner, so that aspirate dust everywhere better.
Press the use and the moving method of vacuum cleaner, can be divided into horizontally, vertical, portable etc., little foreign matters such as dust clean: ground such as vertical easy cleaning woollen blanket with comparalive ease in the wherein horizontal family that is mainly used in; The portable narrow positions such as step, desktop of easily cleaning.
In addition, vacuum cleaner can be divided into filer element type, cyclone type to the mode that foreign matters such as dust, hair filter by it.Wherein filer element type makes the air that contains foreign matter flow through a kind of dry goods dust bag, foreign matter filtered to change dust bag periodically, and cyclone type makes the suction air generation swirling flow that contains foreign matter, fall the bottom surface with sucking the deadweight effect tenesmus of airborne foreign matter in rotary course, do not need dust bag, its use amount just constantly rises.
The air suction apparatus mainly comprises motor and fan, as shown in Figure 1, the right side of figure is the front portion of dust catcher, and prior art is that motor 4 is fixing by former and later two rubber blankets 1 in motor cavity 5, rubber blanket 1 is fixed on the support 9, and motor 4 surfaces are wrapped with one deck sound absorption sponge.
There is following defective in the dust catcher of prior art:
At first, current motor of dust collector is fixed at two ends with block rubber, can not well reduce vibration, causes dust collector vibration excessive, life-span of dust catcher is constituted a threat to, and influence the evaluation of noise.
Secondly, lack the noise reducing apparatus that effectively is used to reduce the noise that motor causes.Simultaneously, in order to reduce noise, adopted the method for the simple suction power that reduces dust catcher.But this method can cause the decreased performance of dust catcher.Therefore, can't eliminate the discontented of the operator that uses dust catcher, thereby cause product image to descend.
Summary of the invention
Technical problem to be solved by this invention is, a kind of suction cleaner using motor cover is provided, and can prevent motor oscillating, eliminates motor noise.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the technical solution adopted in the present invention is:
A kind of air cushion boat form motor of dust collector cover, it comprises motor, motor is held motor cover in it, and described motor cover comprises motor cover protecgulum and motor cover back cover two parts, and wherein the sidepiece at the motor cover back cover is provided with exhaust duct; Be fixedly installed on the fixed block of motor cover back cover afterbody, described fixed block is arranged in the support.
The cylinder of described exhaust duct and motor cover back cover is tangent.
Described motor cover protecgulum and the motor cover back cover composition motor cover that can be fixed together with fastening.
Between motor and motor cover, be provided with rubber blanket.
Motor cover back cover afterbody be formed with that rubber blanket is complementary to outer lug, described rubber blanket just is embedded in the motor cover back cover because of in the formed inner depression of outer lug.
Fixed block offers the perforate that is complementary with projection.
The invention has the beneficial effects as follows: the reaction force that motor cover structure of the present invention can effectively be utilized exhaust and produced, offset the part vibrations that motor produced, simultaneously, the reaction force that gas produced of following discharge produces fixed block and moves up in support, produce the gas suspension effect, this just effectively reduces the vibrations of dust catcher, and reduces the noise that has vibrations to cause.
