Description
Technical field
The utility model relates to ultrasonic washing instruments, and in particular to a kind of ultrasonic washing instrument with denoising device.
Background technique
Ultrasonic cleaning is the penetrability and cavitation shock wave for propagating generation in the medium using sound wave, to needed for experiment
Instrument is cleaned, and furthermore ultrasonic washing instrument can also provide reaction condition for the dissolution and diffusion of indissoluble object.It is as clear
Washing when equipment uses has the advantages that high efficiency, high cleanliness, compares conventional cleaning process, is more convenient, is economic, practical.Ultrasound
Wave is not only had children outside the state plan in the cleaning device course of work can generate huge noise, meanwhile, the exhaust fan for heat dissipation can also generate very big
Noise, these noises are easy to make people irritated, to reduce working efficiency, be worked in such a case to staff's for a long time
Physical and mental health also easily causes negative impact.
Summary of the invention
To solve problems of the prior art, it is clear to be intended to provide a kind of ultrasonic wave with denoising device for the utility model
Instrument is washed, noise when ultrasonic washing instrument work is utmostly reduced.
The technical scheme adopted by the utility model is a kind of ultrasonic washing instrument with denoising device, including rinse bath,
Shell, the rinse bath are installed with thereon by the opening of shell upper, the rinse bath top setting cleaning lid, the rinse bath
It is made of the outer groove, the inside groove that are arranged, the outer groove, inside groove and shell upper bottom surface are enclosed noise reduction cavity, fill out in the noise reduction cavity
Fill glass silk flosssilk wadding；The outer rooved face is evenly distributed with noise reduction through-hole, the noise reduction shape of through holes different sizes and aperture less than sound wave wave
It is long；The cleaning lid back side and inner surface of outer cover paste soundproof plate respectively.
Further design, the noise reduction through-hole are uniform staggered in outer rooved face.
It further designs, filling glass silk flosssilk wadding in the noise reduction cavity.
Further design, the soundproof plate are damping sound-insulating felt plate, non-woven fabrics or microperforated panel.
The utility model has the advantages that noise reduction cavity made of enclosing in the utility model, forms helmholtz resonance chamber, while utilizing noise reduction
The glass silk flosssilk wadding of intracavitary filling generates resonance or absorption sound energy, and aggravation sound can consume, to make acoustic attenuation, to the greatest extent
The noise of ultrasonic cleaning instrument is reduced, a good working environment is provided for experimenter, improves working efficiency.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model, and Fig. 2 is outer groove schematic surface.
Specific embodiment
Embodiment: a kind of ultrasonic washing instrument with denoising device, as shown in Figure 1 and Figure 2, including shell 1, rinse bath 2,
The rinse bath 2 is installed with thereon by the opening on 1 top of shell, 2 top of the rinse bath setting cleaning lid 3, the rinse bath 2
It is made of the outer groove 21, the inside groove 22 that are arranged, the outer groove 21, inside groove 22 and 1 upper bottom surface of shell are enclosed noise reduction cavity 4, described
Filling glass silk flosssilk wadding 6 in noise reduction cavity 4；21 surface of outer groove is evenly distributed with noise reduction through-hole 5, and 5 shape size of noise reduction through-hole is different
And aperture is less than wave length of sound；3 back side of cleaning lid and 1 inner surface of shell paste soundproof plate 7 respectively.
In practice, since the aperture that 21 surface of outer groove is evenly distributed with noise reduction through-hole 5 is less than wave length of sound, noise reduction cavity 4 forms last of the twelve Earthly Branches nurse
Hereby resonant cavity suddenly, can use helmholtz resonance principle reduces the noise generated when cleaning device work.Noise reduction through-hole 5 is designed to
Different sizes are considered as being connected in series by the helmholtz resonance chamber of many a different sizes, different frequency, when sound wave enters
Noise reduction cavity 4 passes through glass silk flosssilk wadding 6, weakens as different frequency incident acoustic wave, is connected in series helmholtz resonance chamber with different frequency
Intrinsic frequency it is identical when, resonate, sound can consume aggravation, to make acoustic attenuation.
In practice, filling glass silk flosssilk wadding 6 in noise reduction cavity 4 utilizes the pore absorption sound energy of glass silk flosssilk wadding.When sound wave enters drop
Chamber 4 of making an uproar causes air vibration in pore, the friction of air and stiction enable vibrational energy and sound not when passing through glass silk flosssilk wadding 6
It is disconnected to be converted into thermal energy, to make sound energy attenuation, consume a part of sound energy；Another part sound can reach noise reduction through glass silk flosssilk wadding 6
Through-hole 5 when frequency is identical, resonates, sound is enable to decay again；Some reflected sound energy, encounters inside groove 21
It can be reflected again, glass silk flosssilk wadding 6 be again passed by reflection, sound can decay again, so that sound wave be made to decay step by step.
In practice, soundproof plate 7 is pasted at cleaning 3 back side of lid, when ultrasonic cleaning instrument work, lid is cleaned lid 3, in cleaning device
Closed environment can be formed.When sound wave upwardly propagates, cleaning lid 3 is reached, is absorbed by soundproof plate 7；When sound wave to left and right, lower section
When propagation, into noise reduction cavity 4, sound wave is decayed step by step in noise reduction cavity 4, can reduce ultrasonic washing instrument work to the greatest extent
When noise.
In practice, noise reduction through-hole 5 is uniform staggered with 22 surface of outer groove, and sound wave can be improved in this way in 4 internal reflection machine of noise reduction cavity
Rate, the absorption number of raising sound energy, further decreases noise.
