Silent water cup

Abstract

When a cup cover is screwed in or out of a cup opening, abnormal sound generated by friction between a sealing ring and the cup opening can be avoided. A cup body is in threaded connection with a cup cover, a water sealing rib protruding inwards in the radial direction is arranged on the inner wall of an opening of the cup body, and a sealing ring is arranged on the cup cover and abuts against the water sealing rib to seal water. The cup cover comprises an upper cover and a lower cover; the upper cover is in threaded connection with an opening of the cup body; the lower cover is arranged below the upper cover and detachably connected with the upper cover in a magnetic attraction mode. The sealing ring is sleeved on the clamping part at the lower end of the lower cover; the lower cover and the sealing ring can extend into or be pulled out of the opening part of the cup body; when the cover is closed, the sealing ring firstly abuts against the water sealing rib, friction force between the sealing ring and the water sealing rib limits rotation of the lower cover and the sealing ring, and the upper cover is screwed to move downwards to extrude the sealing ring to abut against the water sealing rib tightly to seal water. When the cover is opened, the upper cover is screwed, the lower cover and the sealing ring are limited to rotate by friction force between the sealing ring and the water sealing rib until the upper cover is screwed and moved upwards to be separated from the opening of the cup body, and the upper cover magnetically attracts the lower cover to be taken out together.

[0031] In order to make the technical scheme of the utility model clearer, the following will be combined with the drawings of the utility model to further describe the utility model. Figs. 1 to 6 The utility model is described in detail. It should be understood that the specific embodiments described in the specification are only for the purpose of explaining the utility model, and are not intended to limit the protection scope of the utility model.

[0032] The utility model is a silent water cup, which comprises a cup body 1 and a cup cover which is combined with the cup body 1.

[0033] Specifically, the inner wall of the mouth of the cup body 1 is provided with a water sealing rib 11 protruding radially inward, and a first thread 12 is arranged on the inner wall or the outer side wall.

[0034] Specifically, the cup cover includes an upper cover 2 and a lower cover 3, and the lower cover 3 is connected below the upper cover 2 in a magnetic attraction manner, so that the upper cover 2 and the lower cover 3 can rotate relative to each other and can be very conveniently disassembled and separated.

[0035] The upper cover 2 is provided with a second thread 23 on the upper cover 2, which cooperates with the first thread 12, so that the upper cover 2 can be screwed on the mouth of the cup body 1.

[0036] The upper cover 2 is provided with a cavity 21 in the inner part close to the bottom surface, and a first magnetic attraction member 5 is arranged on the bottom wall of the cavity 21. The first magnetic attraction member 5 can be an iron sheet, a magnet sheet, etc. In the embodiment, the first magnetic attraction member 5 is preferably made of 430 stainless steel, which satisfies the magnetic attraction and also has the characteristics of corrosion resistance.

[0037] The lower cover 3 is provided with a receiving cavity 31 in the inner part close to the top surface, and a second magnetic attraction member 6 is arranged in the receiving cavity 31. In order to cooperate with the first magnetic attraction member 5 made of 430 stainless steel, the second magnetic attraction member 6 in the embodiment is a magnet (the first magnetic attraction member 5 and the second magnetic attraction member 6 can be configured to be attracted by different combinations of iron and magnet). The receiving cavity 31 can be closed by a cover or by a secondary injection molding method.

[0038] Through the above structure, the first magnetic attraction member 5 and the second magnetic attraction member 6 are attracted to each other, so that the lower cover 3 can be adsorbed below the upper cover 2 and can support the rotation of the upper cover 2 and the lower cover 3 relative to each other.

[0039] In order to avoid the situation that the lower cover 3 is adsorbed below the upper cover 2 and is not coaxial, and to ensure that it can be positioned at a fixed point, a positioning recess 22 is arranged on the bottom surface of the upper cover 2, and a positioning protrusion is correspondingly arranged on the top surface of the lower cover 3, and the receiving cavity 31 is arranged at the top end of the positioning protrusion. The positioning protrusion is rotatably limited in the positioning recess 22.

[0040] Specifically, the lower cover 3 is provided with a sealing ring 4, and the sealing ring 4 contacts the water sealing rib 11 to seal the water.

[0041] Further, the sealing ring 4 includes a main body 41 of annular structure, an inner side wall of the main body 41 is provided with a ring groove 42, and an outer side of the main body 41 is further connected with a sealing portion 43, and the sealing portion 43 has a gap with the main body 41.

[0042] Further, the outer side wall of the lower cover 3 is further provided with a clamping portion 32, and the clamping portion 32 in the embodiment is a ring of protrusions. When the sealing ring 4 is sleeved on the lower cover 3, the ring groove 42 is clamped on the clamping portion 32.

[0043] Further, the edge of the lower cover 3 is above the clamping portion 32 and is provided with a pressing plate 33, and the top surface of the sealing ring 4 is in contact with the pressing plate 33.

[0044] Further, the bottom edge of the upper cover 2 is provided with a pressing portion 24 extending downward, and the pressing portion 24 is in contact with the pressing plate 33. When the cup cover is screwed into the mouth of the cup body 1, the sealing ring 4 can be further contacted with the water sealing rib 11 more closely. Especially when the cup body 1 is filled with hot water, the pressing portion 24 can limit the pressing plate 33 from being pushed open by the internal pressure of the cup body 1, so as to avoid the safety accidents caused by hot water leakage.

[0045] In use, the sealing ring 4 is sleeved on the lower cover 3, and then the lower cover 3 is adsorbed below the upper cover 2 to complete the assembly of the cup cover.

[0046] When the cup cover is closed, the cup cover is placed on the mouth of the cup body 1, and then the sealing ring 4 is in contact with the water sealing rib 11, and then the upper cover 2 is screwed. At this time, due to the friction between the sealing ring 4 and the water sealing rib 11, the lower cover 3 will not rotate with the upper cover 2, so as to avoid the friction between the sealing ring 4 and the water sealing rib 11 to produce abnormal sound. The upper cover 2 is screwed downward, the bottom surface of the upper cover 2 presses the top surface of the lower cover 3, the pressing portion 24 of the upper cover 2 presses the pressing plate 33, and the sealing ring 4 is tightly contacted with the water sealing rib 11 to seal the water.

[0047] When the cup cover is opened, the upper cover 2 is screwed, and the friction between the sealing ring 4 and the water sealing rib 11 makes the lower cover 3 stop in contact with the water sealing rib 11, so as to avoid the friction between the sealing ring 4 and the water sealing rib 11 to produce abnormal sound. The upper cover 2 is kept screwed until the second thread 23 is separated from the first thread 12, and at this time, the lower cover 3 is still adsorbed below the upper cover 2. If the upper cover 2 is continued to be screwed, only idle rotation is formed. After the upper cover 2 is lifted, the lower cover 3 is also lifted, that is, the cup cover is rotated and removed from the mouth of the cup body 1.
