Abstract
The invention discloses an exhaust device of a dust collector motor, which comprises an exhaust hood, wherein the top surface of the exhaust hood is provided with a plurality of exhaust holes; the inside of the exhaust hood is provided with a plurality of springs and a plurality of dampers; the upper end of each spring is connected with the top surface of the exhaust hood, while the lower end is connected with a bottom plate; the upper end of each damp is connected with the top surface of the exhaust hood by a connecting rod, while the lower end is connected with the bottom plate; the bottom plate is provided with a plurality of vents; the length and width of the bottom plate are smaller than those of the exhaust hood; and the bottom plate is in an impending state, and can freely move up and down. Because a vibrating mechanism is formed by combining the plurality of springs, the plurality of dampers and the multihole bottom plate which are arranged in the exhaust device together, and when gas is exhausted outwards, the vibrating mechanism is vibrated so as to achieve the effects of consuming gas kinetic energy and reducing gas noise because of the damping action of the dampers.
Description
Technical field
The invention belongs to a kind of exhaust apparatus, be specifically related to a kind of exhaust apparatus that has the motor of dust collector of the damper that can reduce noise.
Background technology
Dust catcher is a kind of household electrical appliance of indoor cleaning health, is used for removing the dust in ground, carpet, wall, furniture, clothing and various slits.In general, dust catcher 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.
In dust catcher when running,, the impeller of motor drives blower fan rotates at a high speed, and the air of dust catcher inside is discharged, and forms instantaneous vacuum in the inside of 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, is discharged to the dust catcher outside again from the gas outlet in the dust bucket of body.Like this, just reach the effect of dust out, clean floor.The suction rate of dust catcher is divided into a plurality of retainings of operating control, adapts to the scope of operation of different cleaning objects such as ground, bed surface, carpet, sofa, corner, so that aspirate dust everywhere better.
Profile classification according to dust catcher can be divided into vertical type dust collector, horizontal dust collector and portable dust collector etc.For dust catcher, no matter be vertical type dust collector or horizontal dust collector or portable dust collector, all be provided with the dust collect plant of assembling dust and foreign matter at inner of dust catcher body, inner dust of assembling of dust collect plant and foreign matter need regularly to remove, to guarantee the normal use of dust catcher.
Vertical type dust collector is an integrally formed structure such as shell and suction inlet and flexible pipe etc., is the bigger vacuum cleaner of volume ratio.Upright vacuum cleaner is mainly used in bigger spaces such as parlor, particularly lays the occasion of carpet on the ground.
Horizontal dust collector and portable dust collector are mainly used in smaller spaces such as family, particularly remove occasions such as dust on metope, furniture and the electrical equipment and foreign matter.
Shown in Fig. 1～3, the dust catcher of prior art comprises casing 1, protecgulum 2, castor 3, motor cavity 4, in motor cavity 4 inside motor 5 is installed, and is provided with hood 6 in the upper end of motor 5.Motor 5 is fixed on the shell 7, between a side of motor 5 and the shell 7 foam-rubber cushion 8 is installed, and 8 pairs of motors 5 of foam rubber cushion have damping effect.The opposite side of motor 5 is provided with air-breathing interface 9, and air-breathing interface 9 is connected with dust-collecting cavity, at the rear portion of air-breathing interface 9 fan 10 is installed, and is provided with hood 6 in the upper end of motor 5.End face at hood 6 forms a plurality of steam vents 11, and filling sponge 12 below hood 6, and the foreign matters such as dust in the gas of 12 pairs of discharges of sponge have the secondary filter effect.
But the hood of the motor of dust collector of prior art is that gas directly discharges, because the speed of gas is very big, bigger kinetic energy is arranged, and more energy is converted into noise, makes noise very big, causes environmental pollution.
Summary of the invention
The present invention proposes for the shortcoming that overcomes the prior art existence, and its objective is provides a kind of exhaust apparatus that has the motor of dust collector of the damper that can reduce noise.
Technical scheme of the present invention is: a kind of exhaust apparatus of motor of dust collector, described motor of dust collector is fixed on the shell, between side of motor and shell, foam-rubber cushion is installed, be provided with air-breathing interface at opposite side, air-breathing interface is connected with dust-collecting cavity, rear portion at air-breathing interface is equipped with fan, is provided with exhaust apparatus in the upper end of motor.
Exhaust apparatus comprises hood, forms a plurality of steam vents, is provided with a plurality of springs and a plurality of damper in the inside of hood at the end face of hood.The upper end of spring is connected with the end face of hood, and its lower end is connected with base plate.
The upper end of damper is connected with the end face of connecting rod and hood, and its lower end is connected with base plate.
Damper comprises that the lower end opens the cylinder of aperture, is provided with plectane and pole in the inside of cylinder.
Spring and damper are arranged between the hood end face two row steam vents in the outer part.
On base plate, form a plurality of passages.
The length of base plate and width are littler than the length and the width of hood, and base plate is vacant state, can the easy on and off activity.
The present invention is because vibrating mechanism of the common composition of a plurality of springs, a plurality of damper and the Porous Base that is provided with in exhaust apparatus, when gas outwards discharges, cause the vibration of vibrating mechanism, again because the damping action of damper reaches the kinetic energy of spent gas, the effect of reduction gas noise.
