Abstract
The utility model relates to a novel noise-reduction dust collector, which comprises a dust collection barrel, a motor lower cover, a motor and a filter. A noise-reduction sponge is arranged at a motor air inlet under the motor, and an air inlet is arranged on the dust collection barrel. The novel noise-reduction dust collector is characterized in that a noise-reduction partition board is arranged between the filter and the motor air inlet, and the noise-reduction sponge is disposed on the noise-reduction partition board. The noise-reduction partition board distributed with regular or irregular holes is additionally arranged in an air inlet channel between the air inlet on the dust collection barrel of the dust collector and the motor, simultaneously, the noise-reduction sponge is covered on the noise-reduction partition board, bending degree of the air inlet channel is improved, so that sound wave energy of the motor is lost when transmitted to the inside of the dust collection barrel, noise of the motor is blocked and is prevented from transmitting outwards via the dust collection barrel from the inside thereof, the possibility that the noise is transmitted out via the dust collection barrel is reduced, and noise of the dust collector during operation is reduced effectively.
Description
Technical field
The utility model relates to a kind of improvement of dust catcher; Relate in particular to a kind of through sound gobo is installed at motor of dust collector lower cover air inlet place; Make the noise of motor of dust collector in through the outside communication process of bucket wall, obtain consume, thereby reach the novel noise reduction noise reduction dust catcher of the effect that reduces noise
Background technology
In the prior art, the basic structure of dust catcher is followed successively by suction port, dedusting chamber, motor, exhaust outlet.And noise reduction dust catcher in the market all is to carry out noise reduction at exhaust outlet, though carried out noise reduction, also has the space of noise reduction to develop from product structure.
Summary of the invention
The purpose of the utility model is: fully open up the noise reduction silence space of dust catcher, a kind of novel noise reduction noise reduction dust catcher is provided, reduce the operating noise of dust catcher to a greater degree.
The technical scheme that realizes the utility model purpose is:
A kind of novel noise reduction noise reduction dust catcher; Said dust catcher comprises dust suction bucket, motor lower cover, motor and filter; Motor air inlet place below the motor is provided with the noise reduction sponge; The dust suction bucket is provided with air inlet, it is characterized in that: be provided with sound gobo between described filter and the motor air inlet, the sound insulation sponge is set on the sound gobo.
Described sound insulation sponge comprises sound insulation sponge A and sound insulation sponge B, and wherein sound insulation sponge A is arranged between sound gobo and the motor lower cover, and described sound insulation sponge B is arranged in the sound gobo.
Be provided with bloop in the described sound gobo.This bloop is rule or irregular alignment.
Described sound insulation sponge B be arranged on bloop in the sound gobo above.
The novel noise reduction noise reduction dust catcher that the utility model provides; Compare existing dust catcher and only be provided with on the basis of noise reduction sponge at original motor air inlet place, air inlet increases the sound gobo that setting has rule or irregular pore size distribution in the air intake passage the motor on by dust catcher dust suction bucket, on sound gobo, covers the sound insulation sponge simultaneously; Sound gobo is blocked in motor air inlet place; Increased the tortuosity of air intake passage, made air intake, the acoustic wave energy of motor is being lost in the communication process in the dust suction bucket by the tortuous motor that gets into around the sound gobo; Thereby the noise of motor is cut off; Intercept motor noise and in the dust catcher bucket, outwards propagate, spread out of through the dust suction bucket, the noise when effectively reducing dust catcher work thereby reduced noise through the dust catcher bucket.

The specific embodiment
The utility model person of ordinary skill in the field the embodiment of the utility model is described with reference to the accompanying drawings, so that can implement the utility model easily.
See also shown in Figure 1; Present embodiment dust catcher dust suction bucket 8, be installed in motor lower cover 1, the motor 2 on the dust suction bucket 8 and be installed in the filter 7 on the motor lower cover 1; Motor air inlet 11 places below the motor 2 are provided with noise reduction sponge 4, and dust suction bucket 8 is provided with air inlet 9, and the space between the motor air inlet 11 below air inlet 9 and the motor 2 constitutes air intake passage; Sound gobo 6 is arranged in this air intake passage; And between filter 7 and motor air inlet 11, be fixed on the motor lower cover 1, as shown in Figure 2.Sound insulation sponge A 3 is arranged between sound gobo 6 and the motor lower cover 1, and sound insulation sponge B 5 is arranged in the sound gobo 6.Can be provided with bloop 12 in the sound gobo 6, this bloop 12 can be the hole of rule or irregular distribution.When being provided with bloop 12 in the sound gobo 6, sound insulation sponge B 5 be arranged on this bloop 12 above.
Fig. 3, Fig. 4, Fig. 5 are respectively three kinds of enforcement structures of sound gobo 6 in the utility model; Wherein, The lateral cross section of bloop 12 is shaped as polygon in Fig. 3 structure, and the lateral cross section of bloop 12 is for then being circular in Fig. 4 structure, and sound gobo shown in Figure 5 is not provided with bloop 12.Fig. 3 to Fig. 5 only is several kinds of possibility structures that bloop 12 is set on the sound gobo 6, is not expressed as it and only limits to this several kinds of structures.Except the shape of bloop 12 can be a rule or irregularly shaped, the distribution of bloop 12 on sound gobo 6 is random too.
