A silicone rubber plug is fixed at a position on the channel corresponding to the second end, and is provided with a liquid discharge slit in the middle; the liquid heating and ejecting assembly includes a liquid storage housing, a liquid storage tank, a warming device, and a piston, the liquid storage tank is fixed in the liquid storage housing, the warming device is fixed on an outer periphery of the liquid storage tank, and the piston is located inside the liquid storage tank.

Abstract: The invention discloses a locking structure of a cup. The locking structure comprises a cup body and a cup cover. The cup body is provided with a first buckle, and the cup cover is provided with a second buckle adaptive to the first buckle. The locking structure further comprises a lock catch which is movably arranged on the cup cover up and down. The lock catch is provided with a bolt. Correspondingly, the cup body is provided with a bolt hole adaptive to the bolt. The cup cover rotates on the cup body, so that the first buckle and the second buckle are matched. When aligned, the bolt falls into the bolt hole, thereby realizing rotary locking.

Abstract: The present disclosure discloses a massage device with replaceable massage subassemblies, including a stick body and at least one massage subassembly. A printed circuit board (PCB), a first massage module, and a power supply are arranged in the stick body. The PCB is electrically connected to the first massage module and the power supply. A second massage module is arranged in each massage subassembly. The stick body is provided with a conducting sliding rail, and the PCB is electrically connected to the conducting sliding rail. Each massage subassembly is provided with a conducting sheet adapting to the conducting sliding rail. The conducting sheet is capable of sliding in a reciprocating manner on the conducting sliding rail. Therefore, by means of configuring several massage subassemblies, each massage subassembly has a different massage function, so that a user can replace massage subassemblies to achieve different massage modes.
