Abstract: A pre-embedded base device includes a pre-embedded base, a first plug detachably coupled to the pre-embedded base, and second plug detachably coupled to the first plug. The pre-embedded base defines a base water chamber and a water inlet channel in communication with the base water chamber. The first plug has a drainage channel in communication with the base water chamber and a water pipe joint in communication with the drainage channel. When the pre-embedded base device is in an initial configuration, the first plug is coupled to the pre-embedded base, the second plug is coupled to the first plug, the first plug seals the base water chamber, and the second plug seals at least one of the drainage channel or the water pipe joint.

Abstract: A faucet connection structure comprising a faucet, a protective sleeve, an inlet diverting base, and a connecting water pipe. The connecting water pipe plays the role of connecting and securing and passes through the protective sleeve. The connecting water pipe has an upper end that connects to a faucet inlet pipe of the faucet, and a lower end that connects and locks with the inlet diverting base. The protective sleeve is coupled between the faucet inlet pipe and the inlet diverting base, eliminating the need to fix ends of the protective sleeve. This configuration simplifies the mounting steps and increases the mounting efficiency. The configuration allows for no collision to occur during the process of cleaning the protective sleeve. The cleaning process is convenient for users. The protective sleeve can be selected from a wide range of shapes, enriching the appearances of the products.

Abstract: A flexible support includes a first mounting channel for mounting a flexible water pipe, a second mounting channel for mounting a flexible supporting and positioning mechanism, a first connecting end, a second connecting end, and a support body. The support body capable of being bent and deformed. The support body coupled between the first connecting end and the second connecting end. The second mounting channel is located on one side of the first mounting channel. The first mounting channel and the second mounting channel respectively penetrate through the first connecting end, the support body and the second connecting end in sequence.

Abstract: An assembly structure of a lever handle and a valve plug, wherein at least two positioning grooves are formed in the inner surface of a mounting hole of the lever handle which is made of metal, a non-metal clamping member has two pushing wedges inserted in the positioning grooves, and a second connecting portion of the valve plug is inserted in the mounting hole of the lever handle and is axially fixed by a locking member. Plural arc-shaped concave surfaces formed on the pushing edges are abutted against the teeth of the second connecting portion of the valve plug in an interference fit, so as to prevent the looseness between the lever handle and the valve plug and the accelerated wear and tear caused by the fit clearance between the teeth.
