Referring to fig. 1 to 4, the muffler 100 includes a housing 10 and a communication hole pipe 30, wherein an air inlet chamber 11 and an air outlet chamber 12 are disposed in the housing 10 at intervals; the communication hole pipe 30 is installed in the housing 10 and is respectively communicated with the air inlet chamber 11 and the air outlet chamber 12, the communication hole pipe 30 is at least partially disposed in the air outlet chamber 12, and a plurality of air outlet holes 31 are formed in the portion of the communication hole pipe 30 located in the air outlet chamber 12.

In the technical scheme provided by the utility model, the air inlet chamber 11 and the air outlet chamber 12 are arranged in the shell 10 at intervals, and the air inlet chamber 11 and the air outlet chamber 12 are communicated through the communication hole pipe 30, so that when noise and air enter the silencer 100, the air inlet chamber 11 forms an expansion chamber, when sound waves enter the expansion chamber, reflection and interference can occur in the chamber, a series of sound wave superposition can be formed, the superimposed sound waves can generate phase difference so as to offset a part of sound energy, the silencing effect is achieved, after the air inlet chamber 11 is silenced, the sound waves and air enter the air outlet chamber 12 through the communication hole pipe 30, at the moment, because the aperture of the air outlet hole 31 of the communication hole pipe 30 is smaller, a high-pressure environment can be formed in the communication hole pipe 30, and when the air and the sound waves reach the air outlet chamber 12 from the communication hole pipe 30, the high-pressure environment is changed into the low-pressure environment, so that the air outlet chamber 12 plays a role of an expansion chamber and an expansion chamber, when sound waves enter the air outlet chamber 12, reflection and interference can occur in the chamber to form a series of sound wave superposition, the superposed sound waves can generate phase differences so as to offset a part of sound energy to achieve the silencing effect, and in the air outlet chamber 12, a propagation medium of the sound waves can expand to consume the energy of the sound waves, compared with the traditional scheme of silencing the expansion chamber, in the utility model, the air outlet chamber 12 has the functions of the expansion chamber and the expansion chamber through the cooperation of the communication hole pipe 30, the air inlet chamber 11 and the air outlet chamber 12, and the silencing capability of the silencer 100 on high-frequency noise is remarkably improved.

The formation of the air inlet chamber 11 and the air outlet chamber 12 is not limited, and two separate chambers may be directly formed in the housing 10, or one chamber may be formed in the housing 10, and the air inlet chamber 11 and the air outlet chamber 12 may be separated by the partition 20, which is not limited herein. The mid muffler 100 of the present embodiment belongs to the suction muffler 100.

It should be emphasized that the opening positions of the plurality of air outlet holes 31 are not limited, and may be at the end of the communicating hole pipe 30 or at the side of the communicating hole pipe 30, and only need to be in the air outlet chamber 12, where the shape of the air outlet holes 31 is not limited, and may be a square hole, a circular hole, a triangular hole, or the like, and in this embodiment, the air outlet holes 31 are circular holes for convenience in processing and manufacturing.

It will be appreciated that the smaller the aperture of the air outlet hole 31, the smaller the corresponding air outlet amount, the larger the pressure difference between the communication hole pipe 30 and the air outlet chamber 12, and when the air flows out to the air outlet chamber 12 through the air outlet hole 31, the corresponding expansion effect is better, the larger the energy of the consumed sound wave, the better the effect of the air outlet chamber as the expansion chamber is to be muffled, but the smaller the corresponding air outlet amount is, and the larger the aperture is, the smaller the pressure difference between the communication hole pipe 30 and the air outlet chamber 12 is, and the corresponding air outlet chamber 12 is the worse the effect of the air outlet chamber as the expansion chamber is.

And, the principle of the expansion cavity is that when the sound wave enters the air outlet cavity 12, reflection and interference can occur in the cavity to form a series of sound wave superposition, and the superimposed sound waves can generate phase difference so as to offset a part of sound energy and achieve the silencing effect, therefore, the aperture of the air outlet hole 31 is different, and the corresponding noise frequency is not different, so that in order to ensure the air outlet quantity and the acting noise frequency, the aperture of the air outlet hole 31 is 1 mm-5 mm, on one hand, the air outlet quantity can be ensured, and on the other hand, the noise can be reduced aiming at the specific noise frequency.

Specifically, the number of the air outlet holes 31 is not limited, and may be any number greater than 1, for example, two, three, four, etc., and in actual use, may be determined according to the frequency of action of the transmission loss and the amount of suction.

It should be emphasized that the apertures of the plurality of air outlet holes 31 may be the same, and in this case, the noise reduction effect for the noise of the same frequency may be better, or may be different, and the present invention is not limited thereto.

In other embodiments, a plurality of air outlet holes 31 may be formed in the communicating hole pipe 30, and the air outlet holes 31 may be configured to be opened and closed, for example, a valve is disposed at the air outlet hole 31, a corresponding setting control device is connected with the valve in a communication manner, and the corresponding air outlet holes 31 are controlled to be opened and closed according to a selected operating frequency and an air suction amount, so that a plurality of specific frequencies can be muffled, and the effect of muffling can be further improved according to self-adaptive adjustment of the air suction amount.

Of course, in a further embodiment, the aperture of the air outlet hole 31 may be set to be different, so that the frequency range of the air outlet hole is wider.

Further, the opening positions of the plurality of air outlet holes 31 are not limited, and may be at the end of the communication hole pipe 30, or may be at the side of the communication hole pipe 30, and only need to be in the air outlet chamber 12, which is not limited herein, in an embodiment, the plurality of air outlet holes 31 are disposed at the circumferential side of the communication hole pipe 30, and the plurality of air outlet holes 31 are correspondingly disposed at the circumferential side of the communication hole pipe 30, so that the gas propagation range flowing out from the air outlet holes 31 can be wider, the expansion effect is better, and the sound cancellation effect is better.

Meanwhile, the end of the communication hole pipe 30 located in the air outlet chamber 12 may be in a closed arrangement, specifically, the form of the closed arrangement is not limited, and the end of the communication hole pipe 30 located in the air outlet chamber 12 may be directly closed, or the end of the communication hole pipe 30 located in the air outlet chamber 12 may be directly abutted against the chamber wall of the air outlet chamber 12, thereby realizing the closing, and the like, which is not limited herein.

Further, it will be appreciated that the acoustic cancellation principle of the expansion chamber is that the reflected and interfered sound waves form a series of superimposed sound waves, which are phase-shifted to cancel a portion of the acoustic energy and achieve the acoustic cancellation effect, so that the length of the communication port tube 30 in the expansion chamber determines the frequency of the acoustic wave to be applied for the acoustic cancellation, and in one embodiment, the communication port tube 30 has a first communication section 32 in the inlet chamber 11 and a second communication section 33 in the outlet chamber 12, the length of the first communicating section 32 is different from the length of the second communicating section 33, so that in this embodiment, the lengths of the communicating hole pipes 30 in the air inlet chamber 11 and the air outlet chamber 12 are different, so that the frequencies of the active silencing are different, and thus, the silencing capability of the silencer 100 is further improved.

In addition, if all the gas in the gas inlet chamber 11 is transmitted through the communication hole pipe 30, the gas outlet amount is limited to affect the working efficiency of the compressor, and therefore, the muffler 100 further includes a communication pipe 40 installed in the housing 10 and communicating the gas inlet chamber 11 and the gas outlet chamber 12, so that the gas in the gas inlet chamber 11 is partially conducted to the gas outlet chamber 12 through the communication pipe 40 to increase the gas outlet amount.

In the technical solution of the present embodiment, after entering the air inlet chamber 11, a part of the air and the sound wave is introduced into the air outlet chamber 12 through the communication pipe 40, and another part of the air is introduced into the air outlet chamber 12 through the communication hole pipe 30, so that the air outlet amount can be ensured, and the occurrence of the phenomenon of excessive pressure in the communication hole pipe 30 is avoided.

In this regard, when the pipe diameters of the communicating pipe 40 and the communicating pipe 30 are different, the sound waves with different frequencies can be silenced, and, considering the air output, in an embodiment, the pipe diameter of the communicating pipe 40 is larger than the pipe diameter of the communicating pipe 30, in the technical scheme of this embodiment, the pipe diameters of the communicating pipe 40 and the communicating pipe 30 are set to be different, so that the sound waves with different frequencies can be silenced, and the pipe diameter of the communicating pipe 40 is larger than the pipe diameter of the communicating pipe 30, so that more air can be conveyed from the air inlet chamber 11 to the air outlet chamber 12, and the working efficiency of the compressor is ensured.

Meanwhile, the lengths of the communication pipe 40 in the air inlet chamber 11 and the air outlet chamber 12 may be equal or unequal, which is not limited herein, and in an embodiment, in order to mute sound waves with more frequencies, the communication pipe 40 has a first pipe section 41 in the air inlet chamber 11 and a second pipe section 42 in the air outlet chamber 12, and the lengths of the first pipe section 41 and the second pipe section 42 are unequal, where the frequencies of the first pipe section 41 and the second pipe section 42 in the noise transmission loss are different, and in particular, since the lengths of the first pipe section 41 and the second pipe section 42 are unequal, the distances between the first pipe section 41 and the second pipe section 42 and the chamber wall are different, so that the wavelengths of the superimposed sound waves are different, and thus the sound waves with more frequencies can be muted.

In an embodiment, the lengths of the communicating pipe 40 and the communicating hole pipe 30 located in the air inlet chamber 11 are different, and the distances between the ends of the communicating pipe 40 and the communicating hole pipe 30 reaching the chamber wall of the air inlet chamber 11 are different, so that the wavelengths of the superimposed sound waves are different, and thus sound waves with more frequencies can be muffled.
