[0011] Preferably, a second sealing element is provided between the connector and the upper tube; and a first sealing element is provided between the connector and the lower cylinder.

[0012] Preferably, the first seal is made of a composite material of POK and TPE and is integrally molded with the connector through injection molding; the second seal is a sealing ring made of silicone material.

[0013] Preferably, both the upper tube and the lower cylinder have a double-layer vacuum structure.

[0014] Preferably, the upper tube includes an inner tube and an outer tube; a gap layer is provided between the inner tube and the outer tube; a vacuum hole is provided on the outer surface of the outer tube, and a vacuum layer is formed through the vacuum hole in the gap layer; and a decorative part is also included to cover and shield the vacuum hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by adopting the above technical solution, the upper tube and the lower cylinder are detachably connected, which facilitates disassembly and cleaning, avoids dead corners, and makes cleaning more thorough; and by setting plastic connectors, the upper tube and the lower cylinder can be directly connected, avoiding noise generated by friction between metals.

[0016] Further beneficial effects are: by setting a first seal and a second seal to seal the gap between the connector and the upper tube and lower cylinder; and the first seal is made of a composite material of POK and TPE, which makes it less prone to shrinkage and deformation even after repeated long-term immersion in boiling water, thus avoiding problems such as slippage during connection; and then by integral molding through injection molding, the first seal will not fall off, the assembly efficiency is higher, and the number of parts that need to be cleaned is reduced.
