Description
Technical Field
[0001] The utility model relates to the field of faucets, in particular to a basin faucet capable of controlling double water paths with a single handle. Background Art
[0002] A faucet is a water-using device used to control the flow of water, while a sink faucet is a kitchen faucet installed on a sink.
[0003] When using the kitchen sink faucet, the valve core of the kitchen sink faucet can be opened through the handle of the kitchen sink faucet. At this time, the water flow in the pipe connected to the kitchen sink faucet will enter the kitchen sink faucet through the valve core, and finally be sprayed out through the faucet mouth of the kitchen sink faucet for use. The traditional kitchen sink faucet is limited by its own structure and has only a single water channel inside. Although the single water channel can also meet the needs of daily life, as the requirements of water users become higher and higher, domestic water and drinking water will be distinguished. Domestic water is ordinary unfiltered water, and drinking water is filtered clean water. The two water flows have completely different uses. When the faucet can only provide one water flow, it is necessary to add another faucet to the kitchen sink to provide another water flow. Not only does it increase the cost of use, but more faucets are not conducive to being distributed and installed on the kitchen sink, which can easily lead to a situation where the cleaning space of the kitchen sink is reduced, which is not conducive to the use of the faucet. Summary of the invention
[0004] The utility model aims to solve the existing technical problem and provide a kitchen sink faucet with dual water paths controlled by a single handle.

[0038] A front stopper matching the handle head 38 is provided on the front side of the outer wall of the right end of the valve core seat 3 ; a rear stopper matching the handle head 38 is provided on the rear side of the outer wall of the right end of the valve core seat 3 .
[0039] The method of using the utility model is as follows:
[0040] The lower end port of the cold water channel 11 can be used to connect the cold water pipeline, the lower end port of the hot water channel 12 can be used to connect the hot water pipeline, and the lower end port of the drinking water channel 10 can be used to connect the drinking water pipeline. When the opening and closing plate 28 covers and seals the right end opening of the water outlet 24, the right end opening of the lower opening and closing hole 20, the right end opening of the upper front opening and closing hole 21, and the right end opening of the upper rear opening and closing hole 22, the cold water channel 11, the hot water channel 12 and the drinking water channel 10 are all in a closed state.
[0041] When drinking water is needed alone, the handle 6 can be used to drive the connecting rod 27 to rotate forward. At this time, the opening and closing plate 28 rotates forward synchronously. When the opening and closing plate 28 rotates forward, the positions of the switching hole 33 and the water passing gap 35 on the opening and closing plate 28 will change accordingly. When the handle head 38 is driven by the handle 6 to rotate forward to a certain angle, it will be blocked by the front block. The existence of the front block makes it easy to quickly rotate the opening and closing plate 28 into place. At this time, the switching hole 33 moves to the position of the auxiliary hole 34. The auxiliary hole 34 can be connected with the mixing tank 18 through the switching hole 33, and the water passing gap 35 moves to the position of the lower opening and closing hole 20. At this time, the lower opening and closing hole 20 can be connected with the mixing tank 18 through the water passing gap 35, and the upper opening and closing hole 20 is connected. The right end openings of the closing hole 21, the upper rear opening and closing hole 22, and the water outlet hole 24 are still covered and sealed by the opening and closing plate 28. In this case, the drinking water in the drinking water channel 10 can enter the mixing tank 18 through the drinking water channel 10, the water hole 13, the lower opening and closing hole 20, and the water through gap 35 in turn, and then enter the gap between the left end face of the valve core 5 and the bottom of the valve core hole 4 through the switching hole 33 and the auxiliary hole 34 in turn, and then enter the clean water chamber 17 through the connecting channel 36. The drinking water in the clean water chamber 17 can, under the impetus of subsequent water flow, enter the water through gap 8 through the water inlet gap 48 and the through hole 49 in turn. The water flow entering the water through gap 8 is finally sprayed to the outside through the water spray hole 59 of the water outlet seat for use.
[0042] When domestic water is needed, the handle 6 can be rotated backward. At this time, the handle 6 drives the connecting rod 27 to rotate backward through the handle head 38, and the opening and closing plate 28 rotates synchronously. When the handle 6 rotates backward for a certain stroke, the handle head 38 will touch the right stopper, indicating that it has been rotated into place and the rotation of the handle 6 is stopped. At this time, the switching hole 33 on the rotated opening and closing plate 28 is connected with the water outlet hole 24, and the upper front opening and closing hole 21 and the upper rear opening and closing hole 22 are just within the coverage range of the water-passing gap 35. The upper front opening and closing hole 21 and the upper rear opening and closing hole 22 are both connected with the water-passing gap 35, and the auxiliary hole 34 and the right end opening of the lower opening and closing hole 20 are shielded and sealed by the left side wall of the opening and closing plate 28 and are in a closed state. At this moment, the cold water pipe The cold water in the hot water pipe will flow into the cold water inlet hole 14 through the cold water channel 11, and then flow into the mixing tank 18 through the upper front opening and closing hole 21 and the water through gap 35 in turn. The hot water in the hot water pipe will flow into the hot water inlet hole 15 through the hot water channel 12, and then flow into the mixing tank 18 through the upper rear opening and closing hole 22 and the water through gap 35 in turn. Then the cold water and hot water are mixed in the mixing tank 18 to form domestic water with the actual required temperature, and flow into the mixing water chamber 16 through the switching hole 33 and the water outlet hole 24 in turn. The domestic water entering the mixing water chamber 16 will flow into the mixing water pipeline 7 through the screw joint 55, and finally be sprayed out through the water outlet joint 57 screwed to the end of the mixing water pipeline 7 for use.
[0043] From the above, it can be known that the utility model can switch between domestic water and drinking water only by turning the handle 6, thereby achieving the effect of controlling two water paths with a single handle, and the two water paths for domestic water and drinking water do not interfere with each other, meeting the different water needs of users. When the two water paths for domestic water and drinking water are integrated in a kitchen sink faucet, there is no need to equip each water flow with a separate faucet, which effectively reduces the number of faucets installed on the kitchen sink, which can not only effectively save the use cost, but also avoid the situation where too many faucets lead to a reduced cleaning range.
[0044] A square head 37 is provided at the center of the right end face of the connecting rod 27, and a handle head 38 opposite to the valve core seat 3 is provided at the lower end of the handle 6. A connecting seat 39 is provided on the inner wall of the handle head 38.

The limiting portion 44 and the left end face of the connecting rod 27 are fixed by a plurality of limiting screws 45 evenly distributed on the circumference. This fixing method facilitates the disassembly and assembly between the docking rod 43 and the connecting rod 27, thereby facilitating the disassembly and assembly of the opening and closing plate 28, and facilitating the maintenance and replacement of the opening and closing plate 28.

The existence of the hidden cover 54 can ensure the tightening effect of the positioning screw 51 while hiding the positioning screw 51.
[0047] The lower end port of the mixing water pipeline 7 is screwed with a screw joint 55 that matches it. The screw joint 55 is tubular, and the outer wall of the lower end of the screw joint 55 is provided with a clamping portion 56 that fits the lower end surface of the insert pipe 47.
