The vibration resistant device also comprises a supporting frame of the motor which is arranged in a shell of a main body and is separated with an upper shell and a lower shell, and supporting frames at both ends of the supporting frame of the motor and a sealed supporting frame are used for fixing the motor; the supporting frames are arranged on the outside of the paddle-wheel cover outer shell, and the bearing installing frame is inserted into and is fixed to a fixed groove of the sealed supporting frame. The present invention has the advantages that the supporting frame of the motor independently arranged in the main body of the dust collector is used for fixing the motor, so vibration and vibration noise generated in the rotation of the motor can be effectively prevented, and the trustworthiness of products is improved.
Description
Technical field
The present invention relates to the invention of dust catcher aspect, particularly be the relevant invention that prevents the motor shock-proofing device for vacuum cleaner of shock transfer.
Background technology
Vacuum cleaner is an attraction of utilizing motor to produce, and rubbish and dust are sucked the electronics cleaning machine that dust storage chamber carries out cleaning together with air.
The noise branch that vacuum cleaner produces has two kinds, a kind of is that the motor rotation produces the vibrations that inhalation power brings, import the vibrating noise of body of dust collector into by the motor support component, another kind is exactly under the driving of motor, the moving air of being discharged at a high speed and the mobile noise that produces.
Below, introduce the motor bracing or strutting arrangement that existing vacuum cleaner reduces vibrating noise.As shown in Figure 1 to Figure 3, have illustrated in vacuum cleaner such as Fig. 1, include: body of dust collector 100; Be connected the prolongation flexible pipe 200 of a side of body of dust collector 100; Prolong pipe 300; Suction nozzle 400.Above-mentioned four partial component are linked in sequence.
Body of dust collector 100 as shown in Figure 2, its structure comprises: upper casing 102; Lower casing 103; The motor room 120 that can produce inhalation power motor 140 is equipped with in inside; Aspirated foreign body is collected the dust storage chamber 110 that is provided with dust-collecting filter 112; Form body casing 101 by upper casing, lower casing.
Above-mentioned motor room 120 as shown in Figure 3, its structure comprises: the shockproof lid 143 of motor 140 is fixed on impeller cover 141 shells; Electric machine assemblies such as motor bracing frame 121 fixed supports 140,141,143; Sealing bracing frame 122 fixed support motors 140 back spherical bearing installing racks 142; Upper casing 102, lower casing 103 form position in correspondence with each other.
Above-mentioned motor bracing frame 121 is to be made of upside motor bracing frame 121a, downside motor bracing frame 121b.Shockproof lid 143 upper periphery faces contact is located at the upside motor bracing frame 121a of upper casing 102, and the lower, outer perimeter face contact of shockproof lid 143 is located at the downside motor bracing frame 121b of lower casing 103;
Above-mentioned sealing bracing frame 122 is made of following structure: holddown groove 122c; Protrusion is formed on the following side seal bracing frame 122a of lower casing 103; Corresponding with following side seal bracing frame 122a, and protrude the last side seal bracing frame 122b that is formed on upper casing 102 inboards.
In the drawing, the symbol 111 that does not have explanation is to prolong flexible pipe combined hole, the 123rd, tap.
After existing vacuum cleaner with said structure lies in ground with suction nozzle 400, connect power supplys for the motor 140 of vacuum cleaner and drive, motor 140 rotations make suction nozzle 400 produce inhalation powers.The air that comprises rubbish such as dust is sucked from suction nozzle 400, by prolonging pipe 300, and prolong after the flexible pipe 200, enter dust storage chamber 110 by suction inlet 111 again.
Rubbish such as dust in the air in the above-mentioned dust storage chamber 110, be collected into the inside of filter 112, rubbish such as dust enter behind motor 140 in the motor room 120 by the air inflow aperture 131 in next door 130, and then are discharged by the outlet 123 that motor room's 120 1 sides form.
The vibrations that the motor 140 of existing vacuum cleaner produces when driving, its major part is caused by the rotation of the impeller of impeller cover 141 inside (not shown).
In order to stop on motor 140, to produce vibrations, shockproof lid 143 is installed on impeller cover 141 outer peripheral faces, but, the reverse that produces in order to prevent the reaction that impeller-driven causes, the outer peripheral face up and down of shockproof lid 143 is fixed in the upper and lower sides motor bracing frame 121, therefore, vibrations are just passed to body casing 101 by upper and lower sides motor bracing frame 121, so the vibrations that shockproof lid 143 can not be stopped to cause.
In addition, the vibrations that produce of motor by motor 140 back spherical bearing installing racks 142, seal cover 144 and sealing bracing frame 122 pass to body casing 101.
Therefore, the vibrations that produce on motor by motor bracing frame 121 and sealing bracing frame 122, are passed to body casing 101, cause trembling of body casing 101, produce vibrating noise.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned technology, a kind of motor shock-proofing device for vacuum cleaner that the vibrations of body of dust collector motor internal produce noise that reduces is provided.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of motor shock-proofing device for vacuum cleaner, its structure comprises the motor that has the impeller cover shell, there is the bearing installing rack back of motor housing, this vibration abatement also comprises and is positioned at body casing, and separate independently electric machine support with upper casing, lower casing, the bracing frame at electric machine support two ends and sealing bracing frame fixed electrical machinery; Wherein bracing frame is contained in the outside of impeller cover shell, and the bearing installing rack inserts in the holddown groove that is fixed on the sealing bracing frame; Described electric machine support comprises independently gripper shoe, and its two ends are bent upwards and prolong bracing frame that has formed the shockproof lid of fixed electrical machinery and the sealing bracing frame that inserts the fixing seal lid.
The invention has the beneficial effects as follows: the present invention adopts at the independent electric machine support fixed electrical machinery that is provided with in body of dust collector inside, the vibrations and the vibrating noise that produce in the time of effectively preventing the motor rotation, the reliability of raising product.
