But the interior of the dislocated openings or labyrinth is difficult to clean.

For ease of cleaning, it is desirable to simplify the offset aperture or labyrinth structure. Reference is made to the Chinese patent publication No. CN 219249951U for disclosure of a cup cover assembly and a food processor.

Because the outer ventilation grooves and the inner ventilation grooves are staggered along the circumferential direction, sound waves are transmitted from inside to outside in a nonlinear manner and bypass, the propagation path of the sound waves can be prolonged, and the sound insulation and noise reduction effects are further improved.

Similarly, because the ventilation holes and the outer ventilation grooves are staggered in the circumferential direction, sound waves are transmitted from inside to outside in a nonlinear manner and bypass, the propagation path of the sound waves can be prolonged, and the sound insulation and noise reduction effects are further improved.

Therefore, through the combination of the structure, the cup cover is guaranteed to have good sound insulation and noise reduction effects.

Because the outer ventilation grooves and the inner ventilation grooves are staggered along the circumferential direction, sound waves are transmitted from inside to outside in a nonlinear manner and bypass, the propagation path of the sound waves can be prolonged, and the sound insulation and noise reduction effects are further improved.

Similarly, because the ventilation holes and the outer ventilation grooves are staggered in the circumferential direction, sound waves are transmitted from inside to outside in a nonlinear manner and bypass, the propagation path of the sound waves can be prolonged, and the sound insulation and noise reduction effects are further improved.

Therefore, through the combination of the structure, the cup cover is guaranteed to have good sound insulation and noise reduction effects.

Therefore, the cup cover structure has the advantages of convenient cleaning and ensuring the cleaning effect.

In this embodiment, the outer ventilation slot 125 extends axially through the outer ventilation peripheral edge 121 and the inner ventilation slot 115 extends axially through the inner ventilation peripheral edge 111. And a gap is formed between the lower end of the outer ventilation peripheral edge 121 and the upper surface of the cup cover main body, and a gap is formed between the upper end of the inner ventilation peripheral edge 111 and the inner top wall of the ventilation cover. Not only can the outer ventilation slots 125 and the inner ventilation slots 115 be used for ventilation and noise reduction, but also the axial gaps can be used for ventilation and noise reduction, so that the ventilation and noise reduction effect is further improved. Because only one ventilation hole is provided, in order to ensure the ventilation area, the ventilation hole 122 has a kidney-shaped structure and extends along the circumference of the ventilation cover.

As shown in fig. 5, at least two outer ventilation open slots 125 are uniformly distributed on the outer ventilation peripheral edge 121 along the circumferential direction, and two inner ventilation open slots 115 are uniformly distributed on the inner ventilation peripheral edge 111 along the circumferential direction. Thus, the two outer air permeable slots are 180 apart and the two inner air permeable slots are 180 apart. Generally, the outer ventilation slots 125 are provided in pairs with the inner ventilation slots 115, and the number can also be increased.

As shown in fig. 3, the circumferential center line of the ventilation hole 122 and the circumferential center line of the outer ventilation slit 125 are circumferentially spaced by an angle α, which ranges from 30 ° to 90 °. Because the angle of avoiding the center of the air hole and the outer ventilation open groove is more than 30 degrees, sound waves passing through the outer ventilation open groove can pass through the air hole after turning, one sound wave turning barrier can be added, the extended sound wave propagation path is ensured to be long enough, and the noise reduction effect is improved.

As shown in fig. 6, the circumferential midlines of adjacent outer and inner ventilation slots 125, 115 are circumferentially spaced apart by an angle β in the range of 60-90 °. The included angle beta is used for guaranteeing a good noise isolation effect, the optimal value is 90 degrees, the expected range is between 60 and 90 degrees, dislocation arrangement is formed, labyrinth sound insulation and noise reduction are achieved, the path of sound wave propagation is prolonged, and a better noise reduction effect is achieved.

In order to further reduce noise, the cup cover main body 11 is provided with a lower ventilation rib 118 extending downwards at a position corresponding to the inner ventilation surrounding edge 111, the lower ventilation rib 118 and the inner ventilation surrounding edge 111 can be at the same radial position, and the inside of the lower ventilation rib 118 is communicated with the inside of the inner ventilation surrounding edge 111. The lower ventilation ribs 118 have noise reduction effect, and the more downwardly extending the lower ventilation ribs, the better the noise reduction effect. The lower ventilation surrounding rib is preferably of a circular ring-shaped structure, and the smaller the diameter is, the smaller the noise is.

In order to prevent the pulp from being pushed to overflow in the pulping process, the vortex liquid flow is prevented from splashing to the lower ventilation surrounding ribs. As shown in fig. 6, the cover main body 11 is provided with a splash-proof enclosure rib 119 outside the lower ventilation enclosure rib 118, and the downward extending length of the splash-proof enclosure rib 119 is longer than that of the lower ventilation enclosure rib 118. The splash guard rib 119 is preferably of circular configuration, corresponding to the lower breathable rib. Splash-proof surrounding ribs prevent vortex liquid flow from splashing to the lower ventilation surrounding ribs on one hand, and noise reduction is carried out together with the lower ventilation surrounding ribs on the other hand.

As shown in fig. 6, the howling effect of the height of the lower ventilation ribs on the rotation of the water/slurry vortex is: the lower the ventilation surrounding rib is (the lower movement is), the better the silencing effect is, but the lower ventilation surrounding rib is more easy to splash when the vortex liquid flow splashes or stops rotating to brake; the higher the lower ventilation surrounding rib is (the upward movement) the poorer the silencing effect is, but the lower ventilation surrounding rib is not easy to splash when the vortex liquid flow splashes or stops rotating to brake. Meanwhile, the smaller the inner diameter of the lower ventilation surrounding rib is, the smaller the sound is transmitted. Specifically, as shown in fig. 6, the inner diameter of the lower ventilation rib is L, and the value range of L is 5-12mm, preferably 8mm. The height of the splash-proof surrounding rib is H, and the value range of H is 5-20mm, preferably 15mm. The height H of the splash-proof surrounding rib is too low to prevent the vortex liquid flow in the cup body from splashing to the lower ventilation surrounding rib, too high and too close to the liquid flow, but to cause the liquid flow to easily splash into the lower ventilation surrounding rib,

in order to ensure that the ventilation cover and the cup cover main body are fixed together, the ventilation cover 12 is provided with a turnbuckle inner peripheral edge 123 at the outer side of the outer ventilation peripheral edge 121, the outer side wall of the turnbuckle inner peripheral edge 123 is provided with an outer turnbuckle 126, and the outer turnbuckle is provided with a stop concave point 127. The cup cover main body 11 is provided with a turnbuckle peripheral edge 113 at the outer side of the inner ventilation peripheral edge 111, an inner turnbuckle 116 is arranged on the inner side wall of the turnbuckle peripheral edge 113, and a stop salient point 117 is arranged on the inner turnbuckle 116. The outer edge 113 of the turnbuckle is located outside the inner edge 123 of the turnbuckle, the inner turnbuckle 116 is buckled with the outer turnbuckle 126, and the stop protruding point 117 is clamped into the stop concave point 127. In particular, four pairs of outer turnbuckles and inner turnbuckles are uniformly distributed along the circumferential direction and are L-shaped, but the directions of the outer turnbuckles and the inner turnbuckles are opposite. The inner turnbuckle and the outer turnbuckle are buckled by rotating the ventilation cover, so that the ventilation cover is locked, and the ventilation cover is prevented from being separated from the cup cover main body by high-pressure driving in the cup body. When the turnbuckle is in place, the stop convex points are clamped into the stop concave points, and in-place hand feeling experience is formed during installation.

It will be appreciated that on the venting cover 12, the outer venting peripheral edge 121 is higher than the turnbuckle inner peripheral edge 123 to facilitate the formation of an up-down drop sound barrier.

Further, as shown in fig. 3, the venting cover 12 may also be provided with a removal handle 124. The air permeable cover is convenient to grasp and bear force when being screwed, so as to be convenient to disassemble and assemble. The cup cover main body 11 is provided with a cup cover handle 15. The cup cover main body 11 is provided with a cup cover sealing ring 14 which is sealed with the cup body. The cup cover main body 11 is provided with a cup cover turnbuckle 114 which is rotationally buckled with the cup body.

As shown in fig. 6, a venting cover sealing ring 13 is disposed between the venting cover 12 and the lid main body 11, and specifically disposed on the outer sidewall of the inner peripheral edge 123 of the turnbuckle. The ventilation cover sealing ring ensures the installation and sealing of the ventilation cover so as to buffer and pre-tighten the ventilation cover and the cup cover main body after installation. The ventilation cover can be installed on the cup cover main body by screwing clockwise, and can be detached from the cup cover main body by screwing anticlockwise.

As shown in fig. 6, the central region of lid body 11 may be configured as a recess 112, and both inner ventilation peripheral edge 112 and turnbuckle peripheral edge 113 extend upwardly from the bottom wall of the recess, with an annular groove being formed between turnbuckle peripheral edge 113 and the inner side wall of recess 112. Wherein the circumferential side wall of the concave part 112 is a conical surface with a large upper part and a small lower part. The arrangement of the concave part avoids on one hand that the height of the cup cover is increased in order to arrange the inner ventilation surrounding edge and the turnbuckle surrounding edge, and on the other hand, the concave part and the ring groove structure form a structure with high and low fluctuation on the bottom surface of the cup cover main body, thereby being beneficial to reflecting noise sound waves and reducing noise.
