The invention provides a sealing ring 2, as shown in fig. 1 and 2, the sealing ring 2 is applied to a soymilk machine to eliminate noise generated in the working process of the soymilk machine, and the sealing ring 2 can be applied to other food processors needing to eliminate noise. The sealing ring 2 is arranged between the cup body 13 of the cooking machine and the machine head assembly and is sleeved on the machine head assembly. The seal ring 2 has a first end surface 201 axially opposite to the head assembly and a second end surface 202 axially opposite to the cup 13, the first end surface 201 being fitted to the head assembly, and the second end surface 202 being fitted to the end surface of the cup 13. The first end face 201 is provided with at least one silencing cavity distributed along the circumferential direction of the sealing ring 2, an air inlet mechanism communicated with the silencing cavity and the inside of the cup body 13, and an exhaust mechanism communicated with the silencing cavity and the outside of the cup body 13, wherein the exhaust mechanism penetrates through the periphery of the sealing ring. The exhaust mechanism is used for exhausting high-temperature and high-pressure gas in the soymilk machine.

According to the technical scheme, the silencing cavity, the air inlet mechanism and the air outlet mechanism are arranged on the sealing ring 2, the volumes of the air inlet mechanism and the air outlet mechanism are smaller than those of the silencing cavity, after sound in the cup body 13 enters the spacious silencing cavity through the narrow air inlet mechanism, larger energy consumption can be generated, and when the sound is discharged out of the sealing ring from the spacious silencing cavity through the narrow air outlet mechanism, the energy of the sound is further weakened, so that the purpose of noise reduction is achieved.

Preferably, as shown in fig. 3, the silencing cavity is provided with at least two sub silencing cavities, and a connecting channel is arranged between every two adjacent sub silencing cavities. The width of the connecting channel is preferably smaller than the width of the sub-muffling chamber. The sub-muffling chambers may be distributed along the circumference of the sealing ring 2, may be distributed along the radial direction of the sealing ring 2, or both. Compared with the mode of only arranging one silencing cavity, the mode of arranging at least two sub silencing cavities in the invention has the advantages that when sound is transmitted from the last sub silencing cavity to the next sub silencing cavity through the connecting channel, the sound transmission channel is changed from large to small and then from small to large, the sound energy is consumed for multiple times, the sound energy is greatly attenuated, and the noise reduction effect is better. The number of the connecting channels arranged between two adjacent sub-silencing cavities is at least two. By arranging a plurality of connecting channels, the sound is split, and the frequency, amplitude and phase of the sound transmitted from the different connecting channels to the next sub-silencing cavity are different, so that the sounds entering the next sub-silencing cavity interfere. In order to make the phases of the sound entering the next sub-muffling cavity different so as to cancel the most energy by interference, in this embodiment, the lengths of each connecting channel are preferably different, so that the peak of the sound transmitted to the next sub-muffling cavity through one connecting channel and the trough of the sound transmitted to the next sub-muffling cavity through the other connecting channel are overlapped as much as possible, and the peak and trough overlap each other so as to cancel the energy of the sound. .

Referring to fig. 4, in an embodiment of the present invention, the silencing cavity includes a first silencing cavity 21 and a second silencing cavity 22, a first connection channel 231 and a second connection channel 232 are disposed between the first silencing cavity 21 and the second silencing cavity 22, the first silencing cavity 21 is communicated with the air intake mechanism, and the second silencing cavity 22 is communicated with the air exhaust mechanism. In this embodiment, the first silencing chamber 21 and the second silencing chamber 22 are preferably distributed along the circumferential direction of the sealing ring, the first connecting channel 231 and the second connecting channel 232 preferably extend along the circumferential direction of the sealing ring, and the length of the first connecting channel 231 is smaller than the length of the second connecting channel 232. After the sound is reflected for multiple times in the first silencing cavity 21, a part of sound is transmitted into the second silencing cavity 22 through the first connecting channel 231, and another part of sound is transmitted into the second silencing cavity 22 through the second connecting channel 232, and as the first connecting channel 231 and the second connecting channel 232 are different and the positions connected to the first silencing cavity 21 and the second silencing cavity 22 are also different, the frequencies, the amplitudes and the phases of the two parts of sound after reaching the second silencing cavity 22 are different, the two parts of sound interfere, and part of energy is counteracted.

Further, the first sound deadening chamber 21 is provided with a first guide groove 241 connected to the second connecting passage 232, and the first guide groove 241 is disposed at an angle to the second connecting passage 232. In this embodiment, the first guiding groove 241 preferably extends along the radial direction of the sealing ring, and forms an included angle of 90 degrees with the second connecting channel 232. By providing the first guide groove 241 and forming an angle with the second connection channel 232, the propagation direction of the sound propagated through the second connection channel 232 can be changed, and thus the frequency, amplitude and phase of the sound can be changed to be different from those of the sound propagated through the first connection channel 231, thereby enhancing interference and reducing noise. Meanwhile, when the sound propagates to the junction of the first guide groove 241 and the second connection channel 232, the sound is reflected at the junction, and the sounds of different frequencies interfere with each other, so that the effect of consuming energy can be also achieved. The junction is preferably an arc surface.

Further, the second sound deadening chamber 22 is provided with a second guide groove 242 connected to the second connecting passage 232, and the second guide groove 242 is disposed at an angle to the second connecting passage 232. The second guide groove 242 preferably extends in the radial direction of the seal ring and forms an angle of 90 degrees with the second connecting channel 232. Since the first connection passage 231 and the second connection passage 232 are disposed in parallel and extend in the circumferential direction of the seal ring 2, the second guide groove 242 is also inclined at 90 degrees with respect to the first connection passage 231. In this way, the sound transmitted from the second guiding groove 242 to the second silencing cavity 22 propagates along the radial direction of the sealing ring 2, and the sound transmitted from the first connecting channel 231 to the second silencing cavity 22 propagates along the circumferential direction of the sealing ring, that is, the propagation directions of the two parts of sound are mutually perpendicular, so that the interference between the two parts of sound is further enhanced, and a better silencing and noise reducing effect is achieved.

Similarly, the first silencing chamber 21 may also be provided with a guide groove connected to the first connecting channel 231, and the guide groove has a certain included angle with the first connecting channel 231; the second sound deadening chamber 22 may also be provided with a guide groove connected to the first connecting passage 231, the guide groove having a certain angle with the first connecting passage 231.

Specifically, the first silencing cavity 21 is rectangular, but of course, it may take other shapes, one end of the first silencing cavity opposite to the air inlet mechanism along the length direction is communicated with the air inlet mechanism, two sides of the other end of the first silencing cavity opposite to the air inlet mechanism along the width direction are respectively provided with an arc wall 211 for connecting the long side wall and the short side wall of the first silencing cavity 21, and the first connecting channel 231 and the second connecting channel 232 are both opened on the long side wall of the first silencing cavity 21. The second sound deadening chamber 22 is circular, the first connection passage 231 is directly connected to the second sound deadening chamber 22, the second connection passage 232 is connected to the first sound deadening chamber 21 through the first guide groove 241, and is connected to the second sound deadening chamber 22 through the second guide groove 242. Specifically, the first connection passage 231 is connected to one end of the second sound deadening chamber 22 in the seal ring circumferential direction, and one end of the second sound deadening chamber 22 in the seal ring radial direction is provided with a second guide groove 242 connected to the second connection passage 232. The second sound-deadening chamber 22 of this circular shape reflects sound in more directions than a rectangular shape, and has a better reflection effect on sound, and thus is more advantageous in changing the frequency and amplitude of sound to attenuate sound energy. Similarly, the circular arc wall 211 on the first silencing chamber 21 has a good silencing effect. Of course, a plurality of protrusions may be provided on the side wall of the sound attenuation chamber, so that the side wall forms an uneven shape, sound is better reflected, and the attenuation of sound energy can be realized.

Preferably, the air inlet mechanism comprises an air inlet penetrating through the sealing ring along the axial direction and an air inlet baffle 254 for sealing the air inlet, one end of the air inlet baffle 254 is connected with the sealing ring 2, and can axially swing relative to the sealing ring under the action of gas in the cup, so that the inside of the cup body 13 is communicated with the silencing cavity. Specifically, the air intake mechanism includes two first air intake slits 251 arranged in parallel, and a second air intake slit 252 connected to the two first air intake slits 251, where the first air intake slits 251 and the second air intake slits 252 each axially penetrate through the sealing ring, and the area surrounded by the two first air intake slits 251 and the second air intake slits 252 forms an air intake baffle 254 in a shape of "pi". Of course, the intake baffle 254 can take other shapes, such as a truncated circle. In the present embodiment, the intake baffle 254 is preferably disposed in the first sound deadening chamber 21. The second air intake slit 252 may be connected to an end portion of the first air intake slit 251 or may be connected to a middle portion of the first air intake slit 251. In order to reduce the discharge of gas when the gas pressure in the cup body is low, the slit width of the first air intake slit 251 and the second air intake slit 252 is preferably between 0.1mm and 0.3 mm. When the air pressure in the cup 13 increases, the high-pressure air expands the first air inlet gap 251 and the second air inlet gap 252, so that the first air inlet gap 251 and the second air inlet gap 252 are widened, the air inlet baffle 254 is opened to form a larger air inlet channel, the high-pressure air in the cup 13 is discharged, and meanwhile, noise in the cup 13 is also discharged from the air outlet. Of course, the air inlet mechanism can also be an air inlet hole penetrating through the thickness direction of the sealing ring. Or, referring to fig. 5, the air inlet mechanism is an air inlet groove 253, one end of the air inlet groove 253 is communicated with the silencing cavity, and the other end extends along the radial direction of the sealing ring to penetrate through the inner periphery of the sealing ring, at this time, the sealing ring is sleeved on the machine head assembly, a gap is formed between the inner periphery of the sealing ring and the machine head assembly, and air enters the air inlet groove 253 from the gap.

Preferably, the exhaust mechanism is an exhaust groove 261, one end of the exhaust groove 261 is communicated with the silencing cavity, and the other end of the exhaust groove extends to penetrate through the periphery of the sealing ring 2 along the radial direction of the sealing ring 2. Of course, the exhaust mechanism may also be a bending groove, that is, after being bent for several times, the exhaust mechanism extends to penetrate the periphery of the sealing ring 2 along the radial direction of the sealing ring or along the direction inclined at a certain angle to the radial direction, so as to exhaust the gas to the outside of the cup 13, and consume the energy of sound through the bent path. Alternatively, the exhaust mechanism may be an exhaust through groove penetrating the outer periphery of the seal ring 2 and penetrating the seal ring 2 in the thickness direction.

As shown in fig. 6 and 7, further, a plurality of first positioning bosses 271 are provided on the second end face 202 of the seal ring 2, the outer peripheral wall of the first positioning bosses 271 being in contact with the inner wall of the cup 13. Specifically, the first positioning bosses 271 are provided in plural, for example, four, and the plural first positioning bosses 271 are uniformly distributed on the second end face 202.
