The thickness T1 is too thick, the first sealing portion 22 has a large elastic force and is not easy to insert the center cap assembly 10, the thickness T1 is too thin, the first sealing portion 22 has a small elastic force and cannot be well abutted against the outer surface of the top of the cup lid 20, and the sealing performance is poor, so that the thickness T1 of the first sealing portion 22 is 0.8mm to 1.5mm, which can make the sealing effect good and facilitate the assembly of the center cap assembly 10.

The skilled person will appreciate that the first sealing portion 22 satisfies at least one of the following four features: 1) the first sealing part 22 surrounds the first sealing ring body 21 and is in a circular truncated cone shape, or comprises a first abutting part used for abutting against the outer surface of the top of the cup cover and a first elastic part connecting the first abutting part and the first sealing ring body; 2) the included angle alpha 1 of the first sealing part 22 relative to the horizontal direction is 15-45 degrees; 3) the length L1 of the first seal portion 22 relative to the first seal ring body 21 is 3mm to 5 mm; 4) the thickness of the first sealing part 22 is 0.8mm to 1.5 mm.

Referring to fig. 4 and 6, the structure of the second sealing portion 23 surrounding the first sealing ring body 21 is not limited as long as the second sealing portion 23 can seal between the center cover body 11 and the soundproof cover 40. In fig. 4, the second seal portion 23 may be formed in an inverted truncated cone shape (inverted truncated cone shape) around the first seal ring body 21, and the first seal portion 22 may be a side wall of the inverted truncated cone shape. The inverted circular truncated cone shape makes the second sealing portion 23 good in sealing performance, and also makes the second sealing portion 23 simple in structure. In other embodiments, the second sealing portion 23 may have other shapes, including a second abutting portion for abutting against the sidewall of the soundproof cover opening 401 and a second elastic portion connecting the second abutting portion and the first sealing ring body 21, wherein the second abutting portion at least realizes sealing between the soundproof cover opening 401 and the center cover main body 11. The elastic portion is used for the second sealing portion 23 to generate elastic deformation and more reliably press the side wall of the soundproof cover opening 401, for example, the second sealing portion is in an inclined N or M shape, and the second elastic portion is an N or M-shaped bent portion. However, in comparison, it is better for the second sealing portion 23 to be in the form of a truncated cone than for the second sealing portion 23 to include the second sealing portion and the second elastic portion because the structure is simpler.

Referring to fig. 5, in some embodiments, the included angle α 2 of the second sealing portion 23 with respect to the vertical direction is 15 degrees to 45 degrees, for example, 15 degrees, 18 degrees, 20 degrees, 23 degrees, 25 degrees, 27 degrees, 30 degrees, 33 degrees, 35 degrees, 38 degrees, 40 degrees, 43 degrees or 45 degrees, if the included angle α 2 is too small, the elastic force of the second sealing portion 23 is too small or too far from the sidewall of the soundproof cover opening 401 to abut against the sidewall of the soundproof cover opening 401, the sealing effect is not good, if the included angle α 2 is too large, the elastic force of the second sealing portion 23 is too large, a large reaction force is applied to the center cover 1 during the installation of the center cover assembly 10, and thus, a large resistance force (for example, a resilience force applied to the second sealing portion 23) is applied to the center cover assembly 10 during the insertion of the center cover assembly 10, and the included angle α 2 is within the above range, not only the tightness is good, but also the resistance of the center cover assembly 10 is small, and the assembly is easy.

Referring to fig. 5, in some embodiments, the length L2 of the second sealing portion 23 relative to the first sealing ring body 21 is 3mm to 5 mm. The length L2 of the second sealing portion 23 is too long, the elastic force of the second sealing portion 23 is large, and the resistance (e.g., resilience) applied during the insertion of the center cover assembly 10 is large, so that the center cover assembly 10 is not easily inserted; the length L2 of the second sealing portion 23 is too short, and the second sealing portion 23 may not abut against the side wall of the soundproof cover opening 401 and cannot seal or cannot tightly abut against the side wall of the soundproof cover opening 401, so that the sealing effect is not good, and in sum, the length L2 of the second sealing portion 23 with respect to the first seal ring body 21 in the above range can make it easy to insert the center cover assembly 10, and also make the sealing effect of the second sealing portion 23 good.

Referring to fig. 5, in some embodiments, the thickness T2 of the second sealing portion 23 is 0.8mm to 1.5 mm. The thickness T2 of the second sealing portion 23 is too small, and the elastic force of the second sealing portion 23 is too small to tightly abut against the side wall of the soundproof cover opening 401, so that the sealing effect is not good; the thickness T2 of the second sealing portion 23 is too large, so that the insertion of the center cover assembly 10 is not easily performed due to the resistance applied to the insertion of the center cover assembly 10, and therefore, the thickness of the second sealing portion 23 is 0.8mm to 1.5mm, which makes it possible to improve the sealing performance and to easily assemble the center cover assembly.
