Abstract

The utility model relates to a dust catcher motor cavity sound isolator. A motor cavity body is connected with a bottom plate. A sealing ring seat is connected with a base. The motor cavity body and the base are connected together by using screws through an installation column A and an insulation column B on the base to integrally form a motor cavity. A motor assembly and a sound isolator are installed in the motor cavity. The sound isolator is sound isolation cotton which is respectively and closely attached on the motor cavity body, the bottom plate and the inner wall of the sealing ring seat. The surface of the sound isolation cotton is formed by flat blocks and spaced concave-convex surfaces. Flame-retardant sound isolation cotton with good sound absorption effect is used and is attached on the inner wall of the motor cavity and the bottom plate. The utility model has the advantages that the structure is compact and simple, the manufacturing and the installation are easy, and the production cost and the processing cost are low. After the sound isolator is used in a dust catcher, since the sound isolation cotton with elasticity and certain micropores has certain sound absorption function, the noise can be decreased by 2-3dB and the other performances of the dust catcher are not affected.

Description

Motor of dust collector chamber sound arrester

Technical field

The utility model relates to the accessory in a kind of dust catcher, and particularly a kind of being installed in is used for reducing the motor of dust collector chamber sound arrester that aerodynamic noise is used in the motor of dust collector chamber.

Background technology

Operation principle according to electric dust collector, it is to utilize motor high speed rotating impeller to rotate at a high speed, make and form parital vacuum in the dust storage chamber, after indoor and outdoor pressure reduction is increased to a certain degree, dust just is inhaled in the dirt bag with air-flow, dust separation is retained in the dirt bag after filtration, pure air after will filtering is at last discharged, because the high-speed gas that impeller produces can produce a kind of very strong aerodynamic noise in process of flowing, the high speed pure air of Pai Chuing changes because of flow separation on every side causes pressure simultaneously, and many reasons such as vibration of motor itself all can produce noise, for improving the comfort level that dust catcher uses, noise must take various measures to reduce.

Patent No. 200620149009.X " dust catcher tubular acoustic silencer ", just provide a kind of on dividing plate, the arrangement that hush pipe is set, path in the hush pipe is run through shelf-shaped and is become air exhaust passage, this structure is less to the resistance of air-flow, but can effectively reduce the noise of eluting gas, can be widely used in the noise reduction noise reduction of various family expenses or commercial vacuum cleaner, but the making of hush pipe, trouble is installed.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of motor of dust collector chamber sound arrester is provided, does not take the useful space of motor cavity, its compact conformation is simple, easily make, cost of manufacture is low, also easily install, can not cause ventilation freely not reduce dust collection efficiency, but can reduce noise.

The technical scheme in the invention for solving the above technical problem, motor of dust collector chamber sound arrester, comprise that the motor cavity is connected with base plate, packing holder is connected with base, and motor cavity, base connect into the whole motor cavity that constitutes by the erection column A on it, erection column B with screw, motor assembly and sound arrester are installed in the motor cavity, described sound arrester Sound-proof material is close to respectively on the inwall of motor cavity and base plate, packing holder, described Sound-proof material surface is a flat blocks, b male and fomale(M﹠F) at interval.

Compared with prior art, advantage of the present utility model is: this sound arrester is simple in structure, only adopted the sound-absorbing material Sound-proof material to stick on the inwall of motor cavity and base plate, easily make, install, the processing cost is low, but can play the effect of noise reduction sound, reduces noise 2-3 decibel, but he can not produce bigger resistance to air-flow, therefore can not influence other performance of dust catcher yet.

Description of drawings

Fig. 1, user mode of the present utility model are analysed and observe reference diagram.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

There is the air vent 8 of multiple tracks annular the centre of base 6, and perimeter injection moulding has ring dividing plate 17, is injected with motor assembly fixed leg 18 and erection column A11 on the base at the place, inboard that encircles dividing plate, is injected with the tubing string 16 at uniform interval on half position of ring dividing plate 17 outer surfaces.

The shape of packing holder 4, size are complementary, match with base 6, filling has the ring Sound-proof material 10 of flat blocks in one half the groove of surface, also can play the effect of noise reduction sound insulation, a lateral edges of no Sound-proof material have the tubing string on the uniform pipe thread that exceeds 15 and the base 6 16 corresponding, cooperate.The reeded surface of packing holder is fastened on the base, and each pipe thread 15 that exceeds on it is inserted make in each corresponding tubing string 16 on bases seal holder ring 4 and base 6 be fastened whole, a plurality of exhaust outlets 5 of formation between the groove of ring dividing plate 17 1 side external surfaces and each tubing string and packing holder 4 also.

Be separately installed with switch 13, socket 2. in the groove on the two symmetrical outside walls of motor cavity 3, there are four erection column B12 the inwall bottom surface and link to each other by the inwall of floor with the motor cavity.

Paste the Sound-proof material 14 of fixed pan piece on base plate 1 inwall.

Sound-proof material 14, cavity Sound-proof material 9, ring Sound-proof material 10 are fire-retardant Sound-proof material.

The lower surface of cavity Sound-proof material 9 is the plane, upper surface is the male and fomale(M﹠F) of orderly arrangement pitch, the convex surface that exceeds is for conical, low concave surface is a circular arc, and exceed identical with low height, cavity Sound-proof material 9 has elasticity and certain micropore, can play the certain absorption effect to noise, can not produce bigger resistance again simultaneously to air-flow, therefore can not influence the heat radiation of the dust collection efficiency and the motor of dust catcher yet, cavity Sound-proof material 9 is spliced on the inwall that is close to motor cavity 3 by four, and respectively by switch 13, socket 2, erection column B12 clamping location.

The motor cavity 3 that cavity Sound-proof material 9 is installed is screwed with the base plate 1 that has Sound-proof material 14 and is integral, packing holder 4 and base 6 chimeric being integral, and by erection column A11 on the base and the erection column B12 on the motor cavity 3, connect into the motor cavity of the important component part band sound arrester of dust catcher with screw, motor assembly 7 is screwed on the fixed leg 18 on base 6 lower surfaces.

During use, motor high speed impeller is rotated, and air inlet 8 air intakes from the base 6, thereby produce high speed airflow and also brought big pneumatic noise, when flowing, air-flow collides male and fomale(M﹠F) on the cavity Sound-proof material 9 and the Sound-proof material 14 on the base plate 1 in motor cavity 3, ring Sound-proof material on the packing holder 4, thereby the length that has increased air current flow reaches the purpose that reduces noise, because of cavity Sound-proof material 9 has certain micropore noise there is the certain absorption effect, therefore noise can dampedly sponge a part, but Sound-proof material is the rubber-like soft material, can not produce inhibition to air-flow.

Meanwhile, ring Sound-proof material 10 on motor cavity 3 packing holders 4 also can absorb a part of noise, also a part of noise is sealed in the motor cavity simultaneously and does not leak, the noise of therefore discharging gas in motor cavity base 6 exhaust outlets 5 has just weakened greatly, thereby plays the noise elimination deadening.
