Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0049] Example 1

[0050] This embodiment provides a muffler structure, such as Figures 1-7 As shown, the muffler structure includes a muffler housing 1 and a baffle assembly 2. The baffle assembly 2 is disposed inside the muffler housing 1, such that the inner cavity of the muffler housing 1 is divided into a first flow channel 3 and a second flow channel 4. The baffle assembly 2 has a through hole 26 for connecting or separating the first flow channel 3 and the second flow channel 4. The outer surface of the muffler housing 1 has a first opening 11 and a second opening 12. The first opening 11 communicates with the first flow channel 3, and the second opening 12 communicates with the second flow channel 4.

[0051] The silencer structure provided by this invention has two silencing channels, a first flow channel 3 and a second flow channel 4. The arrangement of the first opening 11, the second opening 12, and the through hole 26 allows the silencer structure provided in this embodiment to have three different silencing methods: the first method is silencing only through the first flow channel 3, the second method is silencing only through the second flow channel 4, and the third method is silencing through both the first flow channel 3 and the second flow channel 4. Different silencing methods target different noise frequencies. That is, compared with traditional silencers, most of which are basically finalized at the beginning of the design and the transmission loss is already determined, and have the same silencing effect at different operating frequencies of the compressor, the silencer structure provided in this embodiment can correspond the frequency with the silencing method, solving the technical problems of large pressure loss of the silencer affecting the performance when the compressor is running at low frequency, insufficient silencing capacity and large noise when running at high frequency, and the mismatch between the silencing capacity of the silencer and the operating frequency of the compressor.

[0052] More specifically, the first opening 11 and the second opening 12 are distributed along the outer surface of the silencing housing 1. The first opening 11 is close to the center of the silencing housing 1, and the second opening 12 is far away from the center of the silencing housing 1. Correspondingly, the first flow channel 3 is a flow channel close to the center of the silencing housing 1, and the second flow channel 4 is a flow channel far away from the center of the silencing housing 1. Generally, the flow channel close to the center of the silencing housing 1, i.e., the first flow channel 3, has a smaller volume.

[0053] The muffler structure provided by the embodiment has three different muffling modes: first, the first opening 11 is open, the second opening 12 and the through hole 26 are closed, at this time, muffling can be performed only through the first flow channel 3; second, the second opening 12 is open, the first opening 11 and the through hole 26 are closed, at this time, muffling can be performed only through the second flow channel 4; third, the second opening 12 and the through hole 26 are open, at this time, muffling can be performed through the first flow channel 3 and the second flow channel 4 together.

[0054] In specific embodiments, the partition plate assembly 2 includes a first partition plate 21 and a second partition plate 22, the first partition plate 21 is arranged on the side wall of the muffling shell 1 and extends towards the center of the muffling shell 1, the first end of the second partition plate 22 is connected with the first partition plate 21, and the second end of the second partition plate 22 is fixed on the side wall of the muffling shell 1; and the second partition plate 22 is located between the first opening 11 and the second opening 12, and the through hole 26 is arranged on the second partition plate 22.

[0055] Specifically, the first partition plate 21 and the second partition plate 22 are mainly used to divide the cavity in the muffler structure into two parts, i.e., the first flow channel 3 and the second flow channel 4; the first partition plate 21 is a plate-shaped structure arranged along the radial direction of the muffler structure, the second partition plate 22 is an arc-shaped structure arranged along the circumferential direction of the muffler structure, and the second segment of the second partition plate 22 is located between the first opening 11 and the second opening 12, so that the first opening 11 can be in communication with the first flow channel 3, and the second opening 12 can be in communication with the second flow channel 4.

[0056] In specific embodiments, the first partition plate 21 has a third opening 211 and a fourth opening 212, and the first end of the second partition plate 22 is located between the third opening 211 and the fourth opening 212, so that the third opening 211 is in communication with the first flow channel 3, and the fourth opening 212 is in communication with the second flow channel 4.

[0057] Specifically, the third opening 211 and the fourth opening 212 are arranged along the radial direction.

[0058] In this way, after the above specific structure is adopted, the three working modes of the muffler structure are as follows:

[0059] First, the third opening 211 and the first opening 11 are in an open state, and the fourth opening 212, the through hole 26 and the second opening 12 are in a closed state, at this time, gas enters the first flow channel 3 from the third opening 211 and is discharged from the first opening 11; in this case, the muffling cavity volume is the smallest, the muffling amount is lower, but the pressure loss is low, and the influence on the compressor performance is smaller.

[0060] The second, the fourth opening 212 and the second opening 12 are in an open state, the third opening 211, the first opening 11 and the through hole 26 are in a closed state, at this time the gas enters the second flow channel 4 from the fourth opening 212 and is discharged from the second opening 12; compared with the first kind of muffling cavity, the volume of the muffling cavity is increased, and the noise reduction amount is obviously improved.

[0061] The third, the fourth opening 212, the second opening 12 and the through hole 26 are in an open state, the third opening 211 and the first opening 11 are in a closed state, at this time the gas enters the second flow channel 4 from the fourth opening 212, enters the first flow channel 3 through the through hole 26 to realize the resonance noise reduction effect, and is finally discharged through the second opening 12; in this case, the overall noise reduction effect is good, and the noise reduction amount of the specific frequency band (near 1300Hz and near 2600Hz) is significantly improved.

[0062] In specific embodiments, the baffle assembly 2 further comprises a third baffle 23 fixed on the side wall of the muffling shell 1 and extending towards the center of the muffling shell 1, and the second end of the second baffle 22 is connected with the third baffle 23.

[0063] The third baffle 23 is a plate structure, mainly used to realize the connection and fixation of the second baffle 22 and the side wall of the muffling shell 1.

[0064] In specific embodiments, the baffle assembly 2 further comprises a first control module 24 for controlling the opening and closing states of the third opening 211 and the fourth opening 212, and the first control module 24 is arranged on the first baffle 21.

[0065] The arrangement of the first control module 24 makes the muffler structure provided in the embodiment have a higher degree of automation. In specific use process, the opening and closing states of the third opening 211 and the fourth opening 212 can be controlled through the first control module 24, for example, in the first case described above, the first control module 24 controls the third opening 211 to open and controls the fourth opening 212 to close, and in the second and third cases described above, the first control module 24 controls the third opening 211 to close and controls the fourth opening 212 to open.

[0066] In specific embodiments, the baffle assembly 2 further comprises a second control module 25 for controlling the opening and closing states of the through hole 26, and the second control module 25 is arranged on the second baffle 22.

[0067] In specific embodiments, the outer surface of the muffling shell 1 further has a third control module 13 arranged at the first opening 11 and the second opening 12, for controlling the opening and closing states of the first opening 11 and the second opening 12.

[0068] Likewise, the second control module 25 and the third control module 13 also have the functions and roles of the first control module 24, which improves the degree of automation of the entire muffler structure and enables different combinations to be achieved without manual operation, so that the structure of the muffler corresponds to different noise frequencies.

[0069] In specific embodiments, the first control module 24 comprises a first controller 241 and a first opening and closing disc 242, which are connected, the first opening and closing disc 242 is arranged at the third opening 211 and the fourth opening 212, and the first opening and closing disc 242 can control at least one of the third opening 211 and the fourth opening 212 to open;

[0070] Specifically, the first opening and closing disc 242 has a first notch 2421, the shape and size of the first notch 2421 match the third opening 211 and the fourth opening 212, and under the action of the first controller 241, the first opening and closing disc 242 can rotate, when it rotates to the first notch 2421 coincides with the third opening 211, the third opening 211 is opened, and the fourth opening 212 is closed; when it rotates to the first notch 2421 coincides with the fourth opening 212, the fourth opening 212 is opened, and the third opening 211 is closed.

[0071] The second control module 25 comprises a second controller 251 and a second opening and closing disc 252, which are connected, the second controller 251 is arranged at the through hole 26, and the second opening and closing disc 252 can control the through hole 26 to open or close;

[0072] Specifically, the second opening and closing disc 252 has a second notch 2521, the shape and size of the second notch 2521 match the through hole 26, and under the action of the second controller 251, the second opening and closing disc 252 can rotate, when it rotates to the second notch 2521 coincides with the through hole 26, the through hole 26 is opened, when it rotates to the second notch 2521 completely deviates from the through hole 26, the through hole 26 is closed.

[0073] The third control module 13 comprises a third controller 131 and a third opening and closing disc 132, which are connected, the third opening and closing disc 132 is arranged at the first opening 11 and the second opening 12, for controlling the opening and closing state of the first opening 11 and the second opening 12.

[0074] Specifically, the third opening and closing plate 132 has a third notch 1321, the shape and size of the third notch 1321 matches the first opening 11 and the second opening 12, and under the action of the third controller 131, the third opening and closing plate 132 can rotate, when it rotates to the third notch 1321 coincides with the first opening 11, the first opening 11 is opened, and the second opening 12 is closed; when it rotates to the third notch 1321 coincides with the second opening 12, the second opening 12 is opened, and the first opening 11 is closed.

[0075] In specific embodiments, the thickness of the baffle assembly 2 can be adjusted, and the setting position of the baffle assembly 2 can be moved radially along the sound absorber structure, so that the volume of the first flow channel 3 and the second flow channel 4 corresponds to the frequency of the noise.

[0076] That is, by changing the thickness and specific position of the baffle assembly 2, the volume of the first flow channel 3 and the second flow channel 4 can be changed, and the volume is related to the corresponding frequency of the noise; therefore, at the initial design stage, the thickness and position of the baffle assembly 2 can be adjusted to make the sound absorber structure correspond to the frequency of the noise to be eliminated. Of course, the baffle assembly 2 can also be arranged to be movable in the sound absorbing shell 1, and such a sound absorber structure has better applicability.

[0077] In addition, the opening size, shape and position of the third opening 211, the first opening 11, the fourth opening 212, the through hole 26 and the second opening 12 in the embodiment can be changed, and in this way, the sound absorber opening can be changed.

[0078] Embodiment 2

[0079] The embodiment provides a compressor, which comprises the sound absorber structure in the embodiment 1. Figure 8 and 9 As shown in the drawings, the compressor comprises the sound absorber structure in the embodiment 1.

[0080] The compressor provided by the embodiment comprises the sound absorber structure in the embodiment 1, and therefore has all the beneficial effects of the sound absorber structure.

[0081] The compressor further comprises a pump body assembly 6, a cover body assembly 7, a motor assembly 8 and a distribution assembly 9, wherein the pump body assembly 6 and the motor assembly 8 are arranged in the cover body assembly 7, and the distribution assembly 9 is connected with the cover body assembly 7. The pump body assembly 6 comprises a cylinder 61, an upper flange 62, a lower flange 63 and a crankshaft 64, the crankshaft 64 passes through the upper flange 62, the cylinder 61 and the lower flange 63 in sequence, and the sound absorber structure is arranged above the upper flange 62.

[0082] In specific embodiments, the compressor further comprises a main controller 5 capable of controlling the opening and closing states of the first opening 11, the second opening 12 and the through hole 26 according to the operating frequency of the compressor.

[0083] More specifically, the main controller 5 is connected with the first controller 241, the second controller 251 and the third controller 131 respectively; in specific use, the main controller 5 can receive the operating frequency of the compressor, and control the rotation of the first opening and closing disc 242, the second opening and closing disc 252 and the third opening and closing disc 132 through the first controller 241, the second controller 251 and the third controller 131, so as to realize the control of the third opening 211, the first opening 11, the fourth opening 212, the through hole 26 and the second opening 12.

[0084] In specific embodiments, when the operating frequency of the compressor is lower than f, the silencer structure silences through the first flow channel 3; when the operating frequency f of the compressor satisfies: 31Hz≤f≤80Hz, the silencer structure silences through the second flow channel 4; when the operating frequency f of the compressor satisfies: f>80Hz, the silencer structure silences through the first flow channel 3 and the second flow channel 4 together.

[0085] Specifically, when the working mode of the silencer structure is the first mode, i.e. the third opening 211 and the first opening 11 are in the open state, and the fourth opening 212, the through hole 26 and the second opening 12 are in the closed state, from Figure 10 It can be seen that this mode has the smallest silencing amount in 0-1500Hz and 2000-5000Hz; noise and performance are in a contradictory relationship, the smaller the silencing amount of the silencer, the smaller the pressure loss, and the better the performance; when the compressor operates at low frequency (lower than 31Hz), the noise generated is small, and the demand for silencing amount of the silencer is small, so the first mode is selected to meet the noise demand while improving the performance level.

[0086] When the working mode of the silencer structure is the second mode, i.e. the fourth opening 212 and the second opening 12 are in the open state, and the third opening 211, the first opening 11 and the through hole 26 are in the closed state, from Figure 10 It can be seen that this mode has a larger silencing amount in 0-1500Hz and 2000-5000Hz than the first mode; when the compressor operates at 31-80Hz, the noise generated becomes larger with the increase of frequency, and the demand for silencing amount of the silencer becomes larger, so this working mode can meet the noise demand of the compressor.

[0087] When the working mode of the muffler structure is the third mode as described above, i.e., the fourth opening 212, the second opening 12 and the through hole 26 are in the open state, and the third opening 211 and the first opening 11 are in the closed state, the sound waves from Figure 10 It can be seen that this mode significantly improves the sound reduction amount near 1300Hz and near 2600Hz; when the compressor operates above 82Hz, some frequency bands of the compressor will produce prominent noise as the frequency increases, and selecting this working mode can meet the normal noise requirements of the compressor, and has good sound reduction effect on specific frequencies.
