In order to realize the purpose, the technical scheme is as follows:
an air conditioning volute that is effective in noise reduction, comprising:
the air inlet is formed in the end face of the shell;
the ventilation part is arranged on the inner wall of the shell and extends from one end of the shell to the other end of the shell;
the sound absorption cotton is sleeved on the periphery of the shell and is communicated with the ventilation part so as to absorb noise generated by equipment;
the ventilation portion is a cell body, perhaps ventilation portion is the through-hole that is the round platform shape, and the aperture of this through-hole is crescent by inboard to the outside.
In some embodiments, an end face of the air outlet is also provided with a plurality of the ventilation parts, and the sound absorption cotton extends along the end face of the ventilation parts so as to seal the ventilation parts.
In some embodiments, the windward port is formed with a flange inward of the periphery of the windward side, and the periphery of the windward port is designed in an arc shape.
In some embodiments, a plurality of ventilation portions are also arranged on two sides of the air outlet, and the ventilation portions are opposite to the sound-absorbing cotton.
In some embodiments, a purification module is provided at the windward port.
The beneficial effect of this application does:
the sound-absorbing cotton absorbs the wind pressure entering from the windward opening through the ventilating part, so that the noise is absorbed, and the noise is greatly reduced when the air feeder works, so that silent work is realized, and the user experience is good; in addition, the groove body or the round table shape is adopted in the ventilation part to accelerate the conduction speed of noise sound waves and achieve the advantage of avoiding noise generation when the ventilation part starts to work, and finally, through the improvement, the noise can be reduced by 1-2 decibels.

Detailed Description
In order to make the technical problems, technical solutions and advantageous effects solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit the utility model.
Referring to fig. 1 to 6, an air conditioning volute capable of effectively reducing noise includes:
the air conditioner comprises a shell 1, wherein an air duct and an air outlet 2 communicated with the air duct are formed in the shell 1, and an air inlet 3 is further formed in the end face of the shell 1;
the ventilation part 4 is arranged on the inner wall of the shell 1 and extends from one end of the shell 1 to the other end;
the sound absorption cotton 5 is sleeved on the periphery of the shell 1 and is communicated with the ventilation part 4 so as to absorb noise generated by equipment;
referring to fig. 4, the ventilation part 4 is a groove body, and it can be seen that the area of the groove body is large, so that the conduction area between the inner cavity of the casing and the sound-absorbing cotton is enlarged, and the sound-absorbing cotton can absorb noise in a large area;
referring to fig. 5, the ventilation part 4 is a circular truncated cone-shaped through hole, the aperture of the through hole gradually increases from the inner side to the outer side, and the inclined surface of the through hole can guide the noise sound wave to be quickly transmitted to the sound-absorbing cotton, so that the transmission speed is higher, the advantage of avoiding noise generation when the sound-absorbing cotton starts to work is achieved, and finally, the noise can be reduced by 1-2 db through the improvement.
Referring to fig. 1 and 2, the wind pressure enters through the windward port and then spreads to the ventilation part around, due to the dense arrangement of the ventilation part, the wind pressure can be absorbed in a large area and then absorbed by the sound-absorbing cotton, and then the wind pressure is discharged from the air outlet, and no noise is generated in the air exhaust process.
In this embodiment, a plurality of the ventilation portions 4 are also disposed on an end surface of the outlet 2, and the sound-absorbing cotton 5 extends along the ventilation portions 4 so as to seal the ventilation portions 4;
referring to fig. 2, the further noise reduction through the ventilation portion that falls again when airing exhaust, inhale the cotton design of sound and can refer to fig. 1, its bottom is extended, not only can fix a position the spiral case, can also fall the noise in the three direction of air outlet, further promoted the efficiency of making an uproar, improved user's experience and felt.
