Description

Technical Field

[0001] The utility model relates to a drinking vessel, in particular to a cup with a ceramic inner liner. Background Art

[0002] As Figure 1 shown, it is an exploded view of a ceramic inner liner cup in the prior art, which mainly consists of a ceramic inner liner 1 and a stainless steel outer cup body 2 sleeved on the ceramic inner liner 1. Then, the upper edges of the two components are fixed by a pressing ring 12 to complete the assembly of the cup.

[0003] However, in order to prevent the ceramic inner liner 1 from shaking in the outer cup body 2, it is usually necessary to abut the bottom of the ceramic inner liner 1 against the bottom of the inner cavity of the outer cup body 2. However, the rigid connection between the two will increase the risk of the ceramic inner liner 1 being broken, so there is still room for improvement. Summary of the Utility Model

[0004] Aiming at the shortcomings of the prior art, the utility model provides a cup with a ceramic inner liner. The buffer pad can not only ensure the connection stability between the ceramic inner liner and the outer cup body, but also avoid direct contact between the two, thereby reducing the risk of the ceramic inner liner being broken.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A cup with a ceramic inner liner includes a ceramic inner liner and an outer cup body sleeved on the ceramic inner liner. A buffer pad is arranged between the bottom of the ceramic inner liner and the bottom of the inner cavity of the outer cup body. A plurality of slots are annularly arranged at a position close to the edge and on the side close to the ceramic inner liner of the buffer pad. A plurality of plug-in parts are annularly arranged at a position close to the edge of the bottom of the ceramic inner liner and are in interference fit with the plurality of slots one by one.

[0007] By adopting the above scheme, the buffer pad can not only ensure the stable connection between the ceramic inner liner and the outer cup body, but also prevent the bottom of the ceramic inner liner from directly and rigidly contacting the bottom of the inner cavity of the outer cup body, thereby reducing the risk of the ceramic inner liner being broken. The interference fit between the plug-in parts and the corresponding slots can realize the connection between the buffer pad and the ceramic inner liner to realize the pre-positioning of the buffer pad, so as to facilitate the installation of the ceramic inner liner and the buffer pad together in the outer cup body, and further improve the assembly efficiency and convenience of the cup.

[0008] Preferably, a plurality of positioning grooves are distributed on the end face of the buffer pad away from the ceramic inner liner, and a plurality of positioning bumps are distributed on the bottom of the inner cavity of the outer cup body and are respectively clamped in the plurality of positioning grooves.

[0009] By adopting the above scheme, the clamping fit between the positioning bumps and the positioning grooves can realize the circumferential limit between the buffer pad and the bottom of the inner cavity of the outer cup body, thereby preventing the ceramic inner liner from rotating circumferentially in the outer cup body and further improving the stability of the ceramic inner liner.

[0010] Preferably, the buffer pad is made of silica gel.

[0011] With the above solution, silica gel has strong adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. Therefore, it can provide a good service life and elastic buffering performance for the buffer pad.

[0012] Preferably, positioning bumps are provided on the outer side of the opening of the ceramic inner liner, and positioning grooves for the positioning bumps to be snap-fitted are provided on the opening edge of the outer cup body.

[0013] With the above solution, when the ceramic inner liner together with the buffer pad is installed in the outer cup body, through the snap-fitting between the positioning bumps and the positioning grooves, circumferential positioning between the ceramic inner liner and the outer cup body can be achieved, so as to facilitate the precise docking of a plurality of positioning bumps and a plurality of positioning grooves, further improving the assembly efficiency and convenience of the cup.

[0014] Preferably, guiding arc surfaces are provided on both sides of the opening of the positioning groove.

[0015] With the above solution, the guiding arc surfaces can increase the opening size of the positioning groove, thus facilitating the positioning bumps to enter the positioning groove, further improving the assembly efficiency and convenience of the cup.

[0016] Preferably, a locking ring is screwed on the outer side of the outer cup body near the opening, and a pressing ring that presses against the upper opening of the ceramic inner liner to prevent the ceramic inner liner from having longitudinal displacement in the outer cup body is provided around the upper port of the locking ring.

[0017] With the above solution, by longitudinally positioning the ceramic inner liner in the outer cup body through the pressing ring, the locking of the ceramic inner liner and the outer cup body can be completed, thus completing the assembly of the cup. The locking ring screwed on the outer side of the opening of the outer cup body can realize the disassembly and assembly of the pressing ring, thus facilitating the user to disassemble and wash the ceramic inner liner, further improving the use convenience.

[0018] Preferably, a sealing gasket is provided between the pressing ring and the upper port of the ceramic inner liner.

[0019] With the above solution, the sealing gasket can not only improve the sealing performance between the pressing ring and the ceramic inner liner to reduce the risk of water leakage at the opening of the ceramic inner liner, but also increase the friction between the pressing ring and the upper opening of the ceramic inner liner, thus ensuring the stability after the pressing ring and the locking ring are installed.

[0020] Preferably, a ring groove for the sealing gasket to be snap-fitted is provided around the end face of the pressing ring close to the ceramic inner liner.

[0021] With the above solution, the snap-fitting between the sealing gasket and the ring groove can not only realize the disassembly and replacement of the sealing gasket, but also ensure the stability after the two are connected.

[0022] Due to the adoption of the above technical solutions, the utility model has remarkable technical effects: the buffer pad can not only ensure the stable connection between the ceramic inner container and the outer cup body, but also prevent the bottom of the ceramic inner container from directly and rigidly contacting the inner cavity bottom of the outer cup body, thereby reducing the risk of cracking of the ceramic inner container. The interference fit between the plug-in part and the corresponding slot can realize the connection between the buffer pad and the ceramic inner container to realize the pre-positioning of the buffer pad, so as to facilitate the installation of the ceramic inner container and the buffer pad together in the outer cup body, and further improve the assembly efficiency and convenience of the cup.
