The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to its specific embodiment of vacuum cleaner, structure, feature and the effect thereof that foundation the present invention proposes, describe in detail as after.
See also shown in Figure 2, vacuum cleaner of the present invention, it mainly comprises: the main body (50) that is connected by suction line (not shown) with the sucker mechanism (not shown) that air and dust thing together can be sucked; Be arranged on the inner the place ahead of described main body (50) and the dust thing that suction line sucks carried out the dust storage chamber (52) of collection work; Be arranged on the inner rear of described main body (50) and can produce the air blast (54) of inhalation power, described air blast sucks the dust thing by described sucker mechanism and is gone by described dust storage chamber (52) receipts; And the acoustic resonator (60) that is arranged on described main body (50) inwall.Described acoustic resonator utilizes sympathetic response sound absorption principle, by absorbing the sound wave of special frequency channel, has reduced the noise that the driving because of dust catcher produces.
Described acoustic resonator (60) is to make more vigorous exercise and transfer acoustic energy to thermal energy of air molecule, thereby absorb and reduce the helmholtz acoustic resonator of noise, it includes as the lower part: have the resonant chamber (62) of prescribed volume, described resonant chamber can make stimulation people's sense of hearing and cause the special frequency channel sound wave of stress identical with its intrinsic vibration frequency; And for sound wave is entered in the described resonant chamber (62), be provided with input hole (64) in a side of described resonant chamber (62).
In addition, described main body (50) comprising: the main body important document (50a) that has the blast chamber (56) that described dust storage chamber (52) and air blast (54) can be installed; And the body cover (50b) that is engaged in described main body important document (50a) upside.At this, described acoustic resonator (60) is set to a plurality of in the inboard of body cover (50b) with honeycomb type.
Other adds explanation, and the eigentone of above-mentioned acoustic resonator (60) promptly can obtain from following mathematical expression with the resonance frequency (f) that above-mentioned special frequency channel is empathized.Above-mentioned resonance frequency (f) depends on the sound wave of special frequency channel, and therefore above-mentioned resonant chamber (62) can be designed to satisfy the cylinder type with designated volume of following mathematical expression.
＜mathematical expression 〉
L '=L+1.7a herein, above-mentioned f is a resonance frequency, c is a velocity of sound, S is the area of input hole (64), V is the volume of resonant chamber (62), L is the thickness of resonant chamber (62), a is the radius of input hole (64).
The above-mentioned resonant chamber of content according to the present invention (62) can also be designed to shapes such as rectangle or hexahedron except that being designed to cylinder type.
In addition, there are most the sound waves that stimulate people's sense of hearing frequency range in the reality, and along with the variation of the actuating speed of above-mentioned air blast (54), stimulate the frequency range of people's sense of hearing also can change thereupon, therefore in order to absorb the sound wave of most frequency ranges separately respectively, the volume of the resonant chamber (62) of above-mentioned acoustic resonator (60) is designed to have with each frequency range sound wave most forms of respective volume, thereby further reduces noise.
Above-mentioned acoustic resonator (60) not only can be arranged on the upside of aforementioned body (50), can also be arranged in the remaining space in the blast chamber (56) that dust storage chamber (52) and air blast (54) are installed, noise not only can be reduced like this, utilization of space can also be improved.
According to vacuum cleaner of the present invention, its sympathetic response sound absorption principle is as follows.
When the sound wave with special frequency channel is input to when having the resonant chamber (62) of acoustic resonator (60) of same intrinsic frequency with its sound wave, empathize because of the intrinsic frequency of the sound wave of above-mentioned special frequency channel and acoustic resonator (60) and to make above-mentioned acoustic resonator (60) inner air high vibration, thereby the acoustic wave energy of above-mentioned special frequency channel is converted to thermal energy, causes the acoustic wave energy of special frequency channel to weaken.Because the sound wave of special frequency channel is absorbed by above-mentioned acoustic resonator (60), sound wave can not emit to human body, can also reduce noise.
The technological innovation of the vacuum cleaner of the present invention that above-mentioned structure like this constitutes all has many saving graces for technical staff of the same trade now, and the progressive that possesses skills really.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, but every technical solution of the present invention content that do not break away from,, all still belong in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present invention.
