Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom appliances, and in particular to a compact faucet. Background Technology

[0002] A faucet is a common term for a water valve, mainly used to control the flow of water and its intensity. It is a common product in the kitchen and bathroom industry. A compact faucet is a type of faucet characterized by a highly integrated structure and a minimalist overall appearance. For example, the handle and switch are integrated into the entire water pipe, and above the countertop, it appears as a single water pipe, achieving an extremely minimalist look that is favored by the mid-to-high-end market.

[0003] With the continuous development of kitchen and bathroom products and the continuous improvement of users' living standards, the diversification of faucet functions is an inevitable development trend. For example, in the field of kitchen and bathroom faucets, common water needs include domestic water and purified water, and more and more faucet products will choose to integrate different water outlet functions on the same faucet.

[0004] However, the pursuit of ultimate simplicity in compact faucets inevitably limits the overall size of the faucet. Integrating different water outlet functions inevitably leads to structural complexity. The contradiction between complex structure and limited volume is difficult to reconcile reasonably. Therefore, there are currently no products on the market that integrate two water outlet functions in a single pipe. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a compact faucet that rationally distributes the control structures of the two water outlet functions axially and, with the inward and outward conversion of the two channels, realizes the integration of two water outlet functions in a limited space, effectively balancing simplification and multi-functionality.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a compact faucet, including a faucet body, a water outlet module and a water distribution module, wherein the faucet body is provided with a main water outlet channel;

The second control component is used to control the opening and closing of the second water outlet channel.

[0010] The integrated faucet of this application realizes dual-channel water supply. The first channel receives water from the valve core, flows out through the first conversion channel, the main outlet channel, and the first outlet channel. The on / off control of the first channel can be realized by operating the valve core through the first operating unit. The second channel receives water from the water supply channel, flows out through the guide pipe, the second conversion channel, the intermediate pipe, and the second outlet channel. The second control component can realize the on / off control of the second channel.

[0011] The integrated faucet of this application integrates two water outlet functions in a limited space by setting the first operating component at the inlet end of the main water outlet channel and the second operating component at the outlet end of the main water outlet channel. This rationally distributes the control structures of the two water outlet functions axially and, in conjunction with the inward and outward conversion of the two channels, achieves the integration of two water outlet functions, effectively balancing simplification and multi-functionality.

By rotating the handwheel 121, the sealing pin 124 can be driven to slide along the operating hole 113, thereby opening and closing the second water outlet channel 112.

[0061] The integrated faucet of this application realizes dual-channel water supply. The first channel receives water from the valve core 32, flows out through the first conversion channel 411, the main outlet channel 21, and the first outlet channel 111. The first channel can be controlled by operating the valve core 32 through the first operating unit. The second channel receives water from the water supply channel 47, flows out through the guide pipe 42, the transition channel 461, the second conversion channel 412, the intermediate pipe 22, and the second outlet channel 112. The second control component 12 can control the on / off of the second channel.

[0062] The integrated faucet of this application integrates two water outlet functions in a limited space by setting the first operating component 31 at the inlet end of the main water outlet channel 21 and the second operating component at the outlet end of the main water outlet channel 21. This rationally distributes the control structures of the two water outlet functions axially and, in conjunction with the internal and external conversion of the two channels, achieves the integration of two water outlet functions, effectively balancing simplification and multi-functionality.

[0063] Furthermore, such as Figure 1 and Figure 2 As shown, it also includes an installation module 5, which includes a locking connector, a base, a support cylinder, and a locking cylinder. The locking connector is detachably connected to the valve sleeve 44 and presses against the valve seat 45. The base is sleeved on the support cylinder, and both the base and the support cylinder are detachably connected to the locking connector. The locking cylinder is sleeved on the support cylinder and detachably connected to it, forming an installation area between the locking cylinder and the base.

[0064] Specifically, a sealing ring is provided on the outer side of the valve seat for sealing between the valve seat and the valve sleeve, a locking connector presses the valve seat together, and a directional screw is also provided between the valve seat and the valve sleeve.
