Description

Technical Field

[0001] The utility model relates to a drinking utensil, in particular to a pressing shaft water sealing component, a pressing water permeable cover and a cup. Background Art

[0002] When drinking water during work or going out, a cup is generally carried and used.

[0003] To facilitate drinking water, there is a cup cover with exhaust and water permeability functions. The cup cover is generally divided into an upper cover body and a lower cover body. A pressing mechanism is generally arranged at the center of the upper cover body, and a water sealing component is generally arranged in the lower cover body. The water sealing component is generally connected to the shaft end of the pressing mechanism. When the pressing mechanism is pressed, the water sealing component is driven, and the water sealing component moves to exhaust or let water flow out.

[0004] When the cup is filled with hot water, the gas in the cup expands and the air pressure rises. When the air pressure in the cup is relatively high, the water sealing components of the pressing water permeable mechanism, such as a water sealing sleeve, a water sealing cylinder, etc., are also subjected to greater gas pressure. In this case, when pressing the pressing mechanism or the pressing component, since the water sealing component is subjected to greater force, it is difficult to press.

[0005] In addition, in the above-mentioned prior art, since the water sealing connection cylinder plays a role in water sealing and the water sealing connection cylinder itself has a certain depth, after pouring water outwards, some water is likely to remain in the cylinder. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a pressing shaft water sealing component, a pressing water permeable cover and a cup. The component is used to assemble the pressing water permeable cover, and the pressing water permeable cover is used to assemble the cup, which facilitates easy exhaust and pouring water outwards when pressing.

[0007] To solve the above technical problems, the utility model adopts the following technical means:

[0008] A pressing shaft water sealing component includes a pressing shaft and a water sealing piece. The pressing shaft includes a shaft cap and a shaft body. One end of the shaft body is the shaft cap. The shaft body is provided with a reset spring setting part, a first water sealing groove, a water sealing piece sliding connection part, a second water sealing groove and a limiting part. The end of the shaft body with the shaft cap is the reset spring setting part, and a reset spring is sleeved on the reset spring setting part. The other end of the shaft body is sequentially provided with a limiting part, a second water sealing groove, a water sealing piece sliding connection part from the end upwards. The water sealing piece sliding connection part sleeved with the water sealing piece. There is a sliding gap between the connection hole of the water sealing piece and the sliding connection part, and the sliding gap enables the water sealing piece to slide along the water sealing piece sliding connection part under force. The limiting part is connected or arranged at the end of the shaft body, and the limiting part prevents the water sealing piece from detaching from the shaft body. A first sealing rubber ring and a second sealing rubber ring are respectively arranged in the first water sealing groove and the second water sealing groove.

[0009] On the shaft body of the present utility model, a first water sealing groove and a second water sealing groove are provided, and a first sealing rubber ring and a second sealing rubber ring are respectively arranged. The first sealing rubber ring is used to cooperate with the pressing shaft cavity to seal water; the second sealing rubber ring is arranged outside the water sealing piece, and after the water sealing piece is reset, it can seal the gap between the water sealing piece and the shaft body; the water sealing piece cooperates with the water sealing ring rib extending from one side of the lower cover body. When the water sealing piece is driven away from the water sealing ring rib, water can flow out through the gap between the water sealing piece and the water sealing ring rib.

[0010] By providing a sliding connection part for the water sealing piece, when the pressing shaft is stressed and moves, the water sealing piece remains stationary. The cross-section of the pressing mechanism is very small, and the pressure of the hot air inside the cup it receives is very small, so it can be easily pressed. When the pressing shaft moves, the gas inside and outside the cup flows, achieving air pressure balance. When continuing to press, the pressing shaft drives the water sealing piece to continue moving, thereby realizing easy air exhaust and pouring water outwards when pressing.

[0011] In addition, by improving the water sealing connection cylinder into a water sealing piece, the problem that water is easily retained in the water sealing connection cylinder is also solved, which is more beneficial to drinking water health.

[0012] The further preferred technical solutions are as follows:

[0013] The limiting component is a limiting nut.

[0014] By using the limiting nut to be threadedly connected with the end of the shaft body, it is convenient for the connection and disassembly of the water sealing piece.

[0015] The connection hole of the water sealing piece is a circular hole or a special-shaped hole.

[0016] Both the circular hole and the special-shaped hole can achieve connection. However, for special-shaped holes, such as circular holes with edges missing, equilateral triangles, regular polygons, etc., the water sealing piece will not rotate when sliding.

[0017] The shaft body is divided into an upper shaft body and a lower shaft body. Magnets I and II are respectively provided at the connection part of the two parts, and they are magnetically connected through Magnets I and II.

[0018] The shaft body is divided into an upper shaft body and a lower shaft body and is magnetically connected through Magnets I and II, making the connection and disassembly of the two parts of the shaft body more convenient and facilitating the cleaning of the cover body.

At the center of the connecting part, there is a pressing shaft cavity and a pressing cavity extending towards the upper cover body side. Near the edge of the connecting part, there is a water-sealing ring rib extending towards the lower cover body side. Near the water-sealing ring rib of the connecting part, there is a water-permeable part. The shaft body of the pressing shaft is sleeved in the pressing shaft cavity, the shaft cap is close to the pressing component, and one end of the shaft body extending out of the pressing shaft cavity is connected with a water-sealing piece. The diameter of the water-sealing piece is greater than or equal to the diameter of the water-sealing ring rib. The lower cover water-sealing rubber ring is provided with a first sealing part and a second sealing part. The first sealing part is arranged between the side wall of the lower cover body and the water-sealing ring rib, and the second sealing part is arranged at the bottom surface of the water-sealing ring rib.

[0020] By setting a sliding connection part for the water-sealing piece, when the pressing shaft is stressed and moves, the water-sealing piece remains stationary. The cross-section of the pressing mechanism is very small, and the pressure of the hot air inside the cup it receives is very small, so it can be easily pressed. When the pressing shaft moves, the gas inside and outside the cup flows, achieving air pressure balance. When continuing to press, the pressing shaft drives the water-sealing piece to continue moving, thus realizing easy exhaust during pressing and pouring water outwards. In addition, using the water-sealing piece to replace the water-sealing sleeve, water-sealing cylinder, etc. in the prior art for water sealing avoids the problems that there will be water remaining inside the water-sealing sleeve and water-sealing cylinder after pouring water, and it is not easy to pour it clean or all flow back into the cup.

[0021] The upper cover body is provided with an outer cover, and the outer cover opens downward and is buckled on the upper cover body.

[0022] By setting the outer cover, firstly, it protects the upper cover body and keeps it clean and hygienic; secondly, it can be taken off and used as a cup when drinking water, which is convenient for drinking hot water. To facilitate the connection between the water-permeable cover and the cup, the outer cover and the upper cover body are provided with vertically arranged and mutually cooperating limit grooves and limit ribs. When rotating the cup cover, it is ensured that the outer cover and the upper cover body rotate together.

[0023] Between the upper cover body and the lower cover body, connecting ribs are provided at the outermost edge of the connecting part at intervals.

[0024] By setting the connecting ribs, the connection between the upper cover body and the lower cover body is more stable and it is convenient for mold release.

[0025] Magnets are arranged on the connecting ribs, and 2 - 5 magnets are arranged to facilitate the magnetic attraction between the outer cover and the magnets.

[0026] By setting the magnets, after the outer cover is buckled on the upper cover body, the connection is stable. When the cup is inverted, the outer cover also remains buckled on the upper cover body without falling off.

[0027] One side of the lower cover body is provided with a cup body, and the opening at the upper end of the cup body is connected with the lower cover body.

[0028] One side of the described lower cover body is provided with a filter screen cylinder, and the top end of the filter screen cylinder is connected to the pressing shaft water sealing assembly.

[0029] By setting the filter screen cylinder, it is convenient to use it to hold tea and make tea. The top end of the filter screen cylinder is connected to the pressing shaft water sealing assembly and can be selectively connected to any one of the shaft body, the water sealing piece or the limiting part. The end of the extended part of the shaft body on one side inside the lower cover body can be threadedly connected to the connecting nut arranged at the center of the top of the filter screen cylinder; a connecting ring is arranged on the bottom surface of the water sealing piece, and the connecting ring can be threadedly connected or snap-connected to the filter screen cylinder; the filter screen cylinder can also be connected to the limiting part by a magnetic attraction method or a snap connection method.
