Description

Technical Field

[0001] This utility model relates to the field of bathroom products, specifically to a faucet. Background Technology

[0002] There are many types of faucets available today. Among them, the dual-control faucet uses two inlet connectors at the bottom, and then a control valve is installed between each inlet connector and the outlet. The switching between hot and cold water is achieved by adjusting the flow rate of the two control valves. Compared with the traditional integrated hot and cold water valve core for water temperature adjustment, the dual-control structure has a unique aesthetic appeal and installation stability. Its inlet connector is a conventional external thread connector, which not only meets the requirements for fixing the nut for installation, but also provides a connection base for the installation of the inlet hose. Therefore, the inlet hose connected to this type of faucet has metal (brass) nuts (i.e., internal thread connectors) at both ends, resulting in higher material costs due to its weight. At the same time, the inlet hose cannot be pre-installed when the faucet leaves the factory. It can only be connected after the faucet is installed and the locking nut used to fix the faucet is installed and fixed, in order to avoid interference between the two during installation. Therefore, the installation is also relatively complicated. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a faucet with low production cost and easy assembly.

[0004] To address the above problems, the following technical solution is provided: A faucet includes a water distribution body, which has a first connector, a second connector, and a water outlet. The water distribution body also has a first valve core that controls the flow and size of water between the first connector and the water outlet, and a second valve core that controls the flow and size of water between the second connector and the water outlet. The inner walls of the first connector and the second connector are both provided with internal threads. The faucet also includes a pre-installed hose, which has an external thread connector and an internal thread connector at both ends. There are two pre-installed hoses, and their external thread connectors are pre-installed by screwing into the internal threads of the first connector and the second connector, respectively. The outer walls of the first connector and the second connector are both provided with external threads. Locking nuts are screwed onto the external threads of the first connector and the second connector.

[0005] The present invention is further provided that the external threaded connector is provided with a sealing ring.

[0006] The present invention is further configured such that the water outlet is provided with a water outlet support arm, and the end of the water outlet support arm is provided with a water outlet nozzle.

[0007] The present invention is further configured such that both the first valve core and the second valve core are flow regulating valve cores.

[0008] The present invention is further configured such that the valve stems of the first valve core and the second valve core are each provided with a handle / wheel.

[0009] The present invention is further configured such that a decorative cover is provided outside the water separator, and the first connector and the second connector protrude from the bottom of the decorative cover.

[0010] The present invention is further configured such that the minor diameter of the internal thread of the locking nut is greater than or equal to the maximum profile diameter of the internal thread joint.

[0011] The beneficial effects of this utility model are: 1. By setting internal threads on the inner walls of the first and second connectors, the pre-installed hose external thread connectors can be directly screwed into them at the factory for pre-installation, avoiding the trouble of later installation for users. At the same time, the external thread connectors of the pre-installed hose have a smaller diameter and are lighter in weight than traditional nuts (i.e., internal thread connectors). They can be manufactured using materials with a smaller diameter, effectively saving materials and reducing material costs and / or procurement costs. During installation, simply pass the locking nut through the internal thread connector and the pre-installed hose to the first and second connectors and screw it onto their external threads. Therefore, there will be no mutual interference in the order of installation after pre-installation. Attached Figure Description
