The present invention provides a cup lid assembly 100.

Referring to fig. 1-5, in an embodiment of the present invention, the cap assembly 100 includes:

the upper cover 10 comprises a cover plate 13 and a connecting plate 15 convexly arranged on one side of the cover plate 13, and the connecting plate 15 is provided with a first exhaust port 10 a; the upper cover 10 is a feeding cover of the food processor 200 and can be arranged in a circular shape.

The provision of the connecting portion 37 facilitates the installation of the lower cover 30.

And a sound insulator 50, wherein the sound insulator 50 includes a main body 51 and a communicating portion 53 provided on one surface of the main body 51, the main body 51 is mounted on the upper cover 10 or the lower cover 30, and forms a sound-deadening chamber 11 in cooperation with the cover plate 13 and the connecting plate 15, the communicating portion 53 extends into the sound-deadening chamber 11, a passage 53a is formed in the communicating portion 53, and the passage 53a communicates with the first exhaust port 10 a.

The main body 51 is attached to the upper cover 10 or the lower cover 30, that is, the insulator 50 may be attached to either the upper cover 10 or the lower cover 30. The shape of the main body 51 can be changed to suit the requirement of installing the cover, and for example, the main body can be arranged in a circular plate shape, or in other shapes. The passage 53a communicates the first exhaust port 10a and the agitation cup 230 so that the gas in the agitation cup 230 can be exhausted through the passage 53 a. While the gas is being discharged, sound waves also propagate through this channel 53 a.

According to the technical scheme of the invention, the sound insulating member 50 is adopted, the communicating part 53 of the sound insulating member 50 extends into the silencing cavity 11, the communicating part 53 forms the channel 53a, namely, the channel 53a extends into the silencing cavity 11, and when the gas and the sound are transmitted outwards, the gas and the sound are firstly counteracted and weakened through the main body part 51, so that the sound waves can only enter the silencing cavity 11 through the channel 53 a. The main body 51 prevents the sound wave from directly propagating into the sound-deadening chamber 11, and the main body 51 reduces the energy of the sound wave to reduce the noise for the first time at the main body 51. Then, in the channel 53a, the sound wave comes into contact with the side wall of the channel 53a, and the side wall of the channel 53a also cancels and attenuates the sound wave, so as to reduce the energy of the sound wave once again, i.e., reduce the noise once again in the channel 53 a. Finally, the sound wave enters the sound-deadening chamber 11 through the passage 53a, and the sound wave contacts the wall of the sound-deadening chamber 11, and the wall of the sound-deadening chamber 11 also cancels and attenuates the sound wave, so as to reduce the energy of the sound wave, that is, perform the third noise reduction in the sound-deadening chamber 11. Finally, the sound waves and the gas are discharged through the first exhaust port 10 a. Therefore, the noise generated by the food processor 200 can be effectively reduced.

Referring to fig. 2 to 8, in the present embodiment, a baffle 17 is further protruded from one side of the cover plate 13, the baffle 17 is located in the sound-deadening chamber 11, the connecting plate 15 surrounds the baffle 17, the baffle 17 partitions the sound-deadening chamber 11 into a first chamber 111 and a second chamber 113, and the communicating portion 53 is located in the first chamber 111. The relief opening 31 of the lower cap 30 is available for food to be added. The number of the first exhaust ports 10a may be one or more, and in this embodiment, two first exhaust ports 10a are preferably provided, and the two first exhaust ports 10a are disposed to face each other. The baffle 17 can be provided in two pieces, and two ends of the baffle 17 are connected with the wall of the sound attenuation cavity 11. The baffle 17 can increase the transmission path of the sound wave, and the energy attenuation of the sound wave in the transmission process is intensified. In the process of sound wave transmission, after the sound wave is transmitted by the channel 53a, the sound wave enters the first chamber 111, in the first chamber 111, the sound wave contacts the cover plate 13 and the baffle plate 17, the cover plate 13 and the baffle plate 17 in the first chamber 111 counteract the sound wave, the energy of the sound wave is reduced, so that noise is reduced, then the sound wave is transmitted into the second chamber 113, the sound wave is counteracted through the baffle plate 17 in the second chamber 113 and the chamber wall of the silencing chamber 11, the energy of the sound wave is reduced, so that noise is reduced, and the sound wave is transmitted and played through the first exhaust port 10a which is arranged on the chamber wall of the silencing chamber 11.

Referring to fig. 5, the distance H between the distal end of the communication portion 53 and the cover 13 ranges from: h is more than or equal to 5mm and less than or equal to 10 mm.

The too close distance between the upper end of the communication portion 53 and the cover plate 13 may cause the too close distance between the exhaust port of the channel 53a and the cover plate 13, and the exhaust gas discharged from the food processor 200 has a certain viscosity, and if the too close distance between the exhaust port of the channel 53a and the cover plate 13 may cause the exhaust port of the channel 53a to be blocked, and the exhaust gas cannot be discharged. And a distance of 5mm ensures that the channel 53a is not blocked. The distance between the upper end of the communication portion 53 and the cover plate 13 is too long, the noise reduction effect of the cover plate 13 is reduced, the propagation path of the sound wave is shortened, the contact between the sound wave and the sound insulating member 50 and the wall of the sound-deadening chamber 11 is reduced, and the noise reduction capability is reduced, so that the distance between the top end of the communication portion 53 and the cover plate 13 is 10mm or less.

The path of the sound wave transmission is further increased by the additional sound-deadening chamber 191 between the mounting plate 19 and the connecting plate 15, so that the sound wave comes into contact with the mounting plate 19 and the connecting plate 15 when being transmitted into the additional sound-deadening chamber 191, reducing the energy of the sound wave, thereby reducing noise, and the gas and sound are discharged from the second gas discharge port 10 b.

With reference to fig. 11, further, a projection of the first exhaust port 10a in a horizontal plane is located in a first radial direction of the cover plate 13, and the second exhaust port 10b in a second radial direction of the cover plate 13, where an included angle α between the first radial direction and the second radial direction has a range value: alpha is more than 0 degree and less than 180 degrees.

That is, the first exhaust port 10a and the second exhaust port 10b are not disposed to face each other, and the noise transmitted through the first exhaust port 10a also needs to pass through a certain path to reach the second exhaust port 10 b. Thus, the path of sound wave transmission can be prolonged, and the noise reduction capability of the additional sound attenuation cavity 191 can be enhanced.

Further, the quantity of first gas vent 10a is two, two first gas vent 10a sets up relatively, two first gas vent 10a is located in the projection on the horizontal plane the first radial of apron 13, the quantity of second gas vent 10b is two, two second gas vent 10b sets up relatively, two second gas vent 10b is located in the projection on the horizontal plane the second of apron 13 is radial, first radial with the second is radial perpendicular.

By arranging the first exhaust port 10a and the second exhaust port 10b in the first radial direction and the second radial direction which are perpendicular to each other, the path between the first exhaust port 10a and the second exhaust port 10b can be maximized, and then the propagation of sound can be routed through the longest path, so that the noise contacts more obstacles in the transmission process, and further the noise is attenuated, and the sound propagated through the second exhaust port 10b does not cause damage to the human body and can be reduced to be below 40 decibels.

Referring to fig. 9 and 10, in the present embodiment, the lower cover 30 includes an end cover 32 and a clamping plate 33 extending downward from a surface of the end cover 32, the relief opening 31 is disposed on the end cover 32, the clamping plate 33 surrounds the relief opening 31, and one end of the connecting plate 15 passes through the relief opening 31 and is mounted on the clamping plate 33.
