Description

An improved faucet

technical field

The utility model relates to plumbing and sanitary ware, in particular to an improved water tap.

Background technique

With the improvement of people's living standards, people's requirements for faucets are getting higher and higher. At present, all the water purification faucets on the market have a single handle to control the opening and closing function of the single water outlet of the water purification faucet. It is necessary to use two different water qualities (such as tap water and ultra-filtered water) at the same time, and it is necessary to switch between the two water qualities frequently. However, the current water purification faucets cannot achieve the above switching function, and two valves need to be installed at the same time. , not only takes up space, but also costs a lot. Although the existing water purification faucets also have double water inlets, they are controlled by two valve cores. During use, one of the valve cores may not be completely closed, resulting in mixed water quality. At the same time, there is a hidden danger of impacting the filter element, reducing the filter element service life.

Utility model content

Therefore, aiming at the above problems, the utility model proposes an improved faucet with reasonable structure, convenient use, low manufacturing cost and extended service life.

In order to solve this technical problem, the utility model adopts the following scheme: an improved faucet, including a housing, a water outlet pipe, a first water inlet pipe and a second water inlet pipe, and also includes a two-inlet and two-outlet steering valve core and a valve cap. The two-inlet and two-outlet steering valve core is set on the upper part of the housing, the first water inlet pipe and the second water inlet pipe are respectively installed on the lower part of the housing, and the inside of the housing is provided with a first water inlet channel and a second water inlet channel. channel, a first water outlet channel, a second water outlet channel and a third water outlet channel, the first water inlet pipe communicates with the first water inlet of the two-inlet and two-outlet steering valve through the first water inlet channel, and the second water inlet pipe The second water inlet channel is connected with the second water inlet of the two-inlet and two-outlet steering valve, and the first water outlet of the two-inlet and two-outlet steering valve is connected with the third water outlet channel through the first water outlet channel. The second water port of the two-inlet and two-outlet steering valve communicates with the third water outlet channel through the second water outlet channel, and the water inlet end of the water outlet pipe is penetrated in the housing and communicates with the water outlet of the third water outlet channel in the housing. The bonnet cover is arranged on the spool of the two-input, two-outlet steering valve and controls the opening or closing of the two-inlet, two-outlet steering valve.

As a further improvement, a handle is also provided on the valve cap.

By adopting the aforementioned technical scheme, the beneficial effect of the utility model is: by setting the first water inlet channel, the second water inlet channel, the first water outlet channel, the second water outlet channel and the third water outlet channel on the housing, thus adopting two The inlet and outlet diverter valves selectively control the water inlet and outlet of the first water inlet pipe or the second water inlet pipe respectively, so that only one outlet water will be opened for the two water qualities. When the first water inlet and outlet are turned on, the second water inlet is completely Closed, when the second water inlet and outlet are turned on, the first water inlet is completely closed, so that there will be no mixing of the two water qualities, and only one two-inlet and two-outlet steering valve is needed for coordinated control. The cost is low and will not cause two kinds of water. The impact of water quality on the filter core prolongs the service life of the filter core, and the structure is reasonable and easy to use, which can be widely popularized and applied.

detailed description

The utility model is further described now in conjunction with accompanying drawing and specific embodiment.

Referring to Fig. 1 and Fig. 2, the preferred improved faucet of the present invention includes a housing 1, an outlet pipe 2, a first water inlet pipe 3, a second water inlet pipe 4, a two-inlet and two-outlet steering valve core 5 and a valve cap 6 , the two-inlet and two-outlet steering valve core 5 is arranged on the upper part of the housing 1, the first water inlet pipe 3 and the second water inlet pipe 4 are respectively installed on the lower part of the housing 1, and the first water inlet pipe 4 is provided inside the housing 1. The water inlet channel 11, the second water inlet channel 12, the first water outlet channel 13, the second water outlet channel 14 and the third water outlet channel 15, the first water inlet pipe 3 is diverted through the first water inlet channel 11 and two in and two out. The first water inlet of the valve 5 is connected, and the second water inlet pipe 4 is connected with the second water inlet of the two-inlet and two-outlet steering valve 5 through the second water inlet passage 12, and the two-inlet and two-outlet steering valve 5 is connected to each other. The first water outlet communicates with the third water outlet channel 15 through the first water outlet channel 13, and the second water outlet of the two-input and two-outlet diverter valve 5 communicates with the third water outlet channel 15 through the second water outlet channel 14. The water inlet end of the water pipe 2 is set in the casing 1 and communicates with the water outlet of the third water outlet channel 15 in the casing 1, and the valve cap 6 is set on the valve core of the two-inlet and two-outlet steering valve 5 And control the two-in and two-out steering valve 5 to open or close, and the valve cap 6 is also provided with a handle 61 .

Among them, the two-inlet and two-outlet steering valve adopts the four-hole 90° spool with double ON/OFF function produced by Shanghai Qier Plastic Co., Ltd. on the existing market.

The utility model sets the first water inlet channel, the second water inlet channel, the first water outlet channel, the second water outlet channel and the third water outlet channel on the shell, thereby adopting two-inlet and two-outlet steering valves to selectively control only The first water inlet or the second water inlet and outlet, so that only one kind of water outlet will be opened for two kinds of water quality. When the first water inlet and outlet are turned on, the second water inlet is completely closed. When the second water inlet and outlet are turned on, the second water outlet Once the water inlet is completely closed, there will be no mixing of the two water qualities. Only one two-inlet and two-outlet steering valve is needed for coordinated control. The cost is low, and the two kinds of water quality will not impact the filter element, which prolongs the service life of the filter element. Reasonable, easy to use, can be widely popularized and applied.
