Description

Technical Field

[0001] This utility model relates to the field of bathroom fixtures, and in particular to a three-dimensional sealed push-button switch structure and a faucet structure. Background Technology

[0002] Commercially available faucets with storage racks integrate the storage rack (outer shell) with the water outlet switching mechanism. The water outlet switching button is located on the storage rack panel. In existing designs, the faucet body built into the storage rack is often designed as a single unit to match the outer shell. The inlet and outlet structures, along with the corresponding multiple switching buttons, are all in fixed positions and styles, corresponding one-to-one with the storage rack outer shell (panel). This facilitates further assembly into a complete product. However, there are no standard parts for related products on the market; the styles are diverse, each with different water outlet and inlet arrangements, shapes, and directions. While a single-unit faucet body is convenient to assemble, the diverse products require separate mold development, resulting in higher costs and resource waste, hindering large-scale industrial production.

[0003] Our patent design aims to achieve flexible assembly, low cost, and wide applicability, and is based on a split design. However, during the design process, it was discovered that when using a pipe-type water circuit, there is a certain technical difficulty in achieving a sealed connection between the push-button switch and the pipe-type water circuit. Based on this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, which led to this case. Utility Model Content

[0004] The primary objective of this invention is to develop a three-dimensional sealed push button switch structure that is easy to assemble and has a good sealing effect.

[0005] The second objective of this invention is to develop a faucet structure that can be designed and molded in sections, is easy to assemble, has a good sealing effect, and has low production cost.

[0006] To achieve the above objectives, this utility model discloses a three-dimensional sealed push-button switch structure, comprising at least: a water outlet pipe, the side wall of which has at least one water outlet hole; a switch valve assembly with the same number of water outlet holes; each switch valve assembly comprising at least: a valve core shell, a water outlet connector, a switch valve core, a rotating partition, and a cat's eye pad; the valve core shell is a cylindrical shell with front and rear open conduction, its side wall having a set of through holes matching the cross-section of the water outlet pipe; the rear end of the water outlet connector is a cavity, and the front end has a connector portion, the water outlet connector having a transversely passing through a retaining channel with an open opening matching the cross-section of the water outlet pipe, while the cavity is isolated to form a water passage communicating with the connector portion; the cavity of the water outlet connector is fitted inside the valve core shell, the water outlet pipe passes through both the through hole and the retaining channel, and at least one water outlet hole stops at the open opening of the retaining channel. The valve core is thus formed into a valve core receiving cavity that communicates with the water outlet through hole. The rotating partition is provided with an inlet slot and an outlet slot. The rotating partition is tightly fitted with the switch valve core, and the inlet of the switch valve core is sealed and connected to the inlet slot, and the outlet of the switch valve core is sealed and connected to the outlet slot. The cat's eye gasket is placed in the inlet slot of the rotating partition. The cat's eye gasket is further provided with a sealing irregular surface. The sealing irregular surface is completely fitted with the shape and size of the surrounding water outlet pipe wall of the corresponding water outlet through hole. In the valve core receiving cavity, the inlet of the switch valve core, the inlet slot of the rotating partition, the cat's eye gasket and the corresponding water outlet through hole are tightly fixed and connected in sequence. The water outlet of the switch valve core, the outlet slot of the rotating partition and the water passage of the water outlet connector are sealed and connected. The connector is connected to an external water outlet device, and the opening and closing of the corresponding water outlet device is realized by opening and closing the switch valve core.

[0007] Furthermore, the water outlet connector is designed in an L-shape, with its cavity and connector part presenting an L-shaped structure, and the water passage presented in an angled manner.

[0008] Furthermore, the valve core shell end is provided with threads, and a valve core seat is fastened by the threads to fix the switch valve core in the valve core receiving cavity.

[0009] Furthermore, the water outlet pipe is a round pipe with an arc-shaped sidewall around the water outlet hole. The through hole of the valve core shell and the retaining channel of the water outlet connector are round or arc-shaped to match the water outlet pipe. The sealing irregular surface of the cat's eye pad is an arc-shaped surface, and the sealing irregular surface is completely fitted with the shape of the water outlet pipe wall around the corresponding water outlet hole.

[0010] Furthermore, the opening of the outlet connector is provided with a retainer facing the switch valve core. The retainer is used to hold the combined rotating spacer and the cat's eye pad after they are fitted together, further ensuring the stability of the switch valve core assembly process.

[0011] A faucet structure, including the aforementioned three-dimensional sealed push-button switch structure, further includes: at least one cold water inlet pipe and at least one hot water inlet pipe, a mixing valve core, and a faucet housing; the cold water inlet pipe, hot water inlet pipe, and outlet pipe are respectively connected to the cold water inlet, hot water inlet, and outlet of the mixing valve core, and the cold and hot water flows to the outlet pipe after being mixed by the mixing valve core; the faucet housing has at least two inlet mounting holes and an outlet mounting hole seat group with the same number of outlet holes, respectively used for the cold and hot water inlet pipes to pass through and be installed with the cold and hot water sources during assembly; the outlet mounting hole seat group includes at least one switch hole seat and one outlet hole seat, respectively used for the switch valve core of the corresponding three-dimensional sealed push-button switch structure to be assembled into the valve core receiving cavity through the switch hole seat, and the water outlet device to be installed on the connector through the outlet hole seat; the opening and closing of the external water outlet device at the corresponding outlet hole is realized by the opening and closing of the switch valve core.

[0012] Furthermore, the water outlet pipe is provided with multiple water outlet holes, and the corresponding water outlet device can be turned on / off by the corresponding switch valve core, so as to realize the selection of multiple water outlet devices.

[0013] Furthermore, the faucet shell is equipped with a storage structure, thus realizing both the faucet function and the storage function.

[0014] Furthermore, the at least one cold water inlet pipe, the at least one hot water inlet pipe, the water outlet pipe, and the faucet housing are all arranged horizontally, and the faucet housing is further provided with a horizontal decorative shell, giving it a larger storage area.

[0015] With the above structure, this patented design is ingenious. The sealing irregular surface of the cat's eye pad and the irregular outer wall of the water outlet pipe form a tight fit, creating a three-dimensional sealing effect between the switch valve core and the water outlet pipe using a combination of a rotating partition and a cat's eye pad. This design allows for a variety of water outlet pipe shapes, such as round, square, and elliptical pipes. Even pipes with special shapes can be sealed with corresponding cat's eye pads. The rotating partition, in conjunction with the switch valve core, separates the inlet and outlet water paths, better ensuring the cat's eye pad's conductivity over the inlet water path. This makes the three-dimensional sealed push-button switch structure applicable to a wide range of scenarios and ensures that the design of the inlet and outlet pipes does not require much consideration of the switch valve core's design requirements. This also facilitates the separate design of each valve core and pipe, avoiding the high development costs associated with overall modular design. Attached Figure Description
