By switching the position of the jack 231, an on-off control function can be realized.
When the ejector rod 231 is in the first position state and the adjusting channel 215 is in the opening state, and the flow is required to be adjusted, the valve core 232 is rotated, the valve seat rotates along with the valve core 232, and the valve seat axially moves simultaneously in the rotating process due to the fact that the valve seat is in threaded connection with the valve body, and the relative position between the valve seat and the ejector rod 231 is changed accordingly. And the plug 213 is limited by the ejector rod 231, when the position of the ejector rod 231 is not changed, the position of the plug 213 is determined, namely, the relative position between the plug 213 and the valve seat is changed, and the opening degree of the adjusting channel 215 is changed, so that the flow adjusting function is realized. Since the axial position of the valve core 232 is unchanged during the flow rate adjustment, the filtering effect of the valve core 232 can be reliably ensured.
When maintenance is needed and the flow regulating assembly 23 is removed, the driving action of the ejector rod 231 on the plug 213 disappears, and the plug 213 automatically closes the regulating channel 215 under the action of the first elastic piece 212, so that an automatic flow stopping function is realized.
The multifunctional curved foot has an on-off control function, a flow regulating function and an automatic flow stopping function.
As shown in fig. 16, a faucet with a water mixing function comprises a water mixing valve 02, wherein the water mixing valve 02 is provided with at least two water inlets, and at least one water inlet is connected with a multifunctional curved foot 01. Preferably, the two water inlets are respectively connected with the multifunctional curved foot 01.
Common water mixing valve in market has inherited on-off control, mixed water and proportion regulation's function generally, though compact structure, convenient to use, owing to often adopt single handle to accomplish above-mentioned operation, mixed water proportion regulation has unstable problem, can change mixed water proportion often simultaneously in the in-process of carrying out on-off control operation, influences the result of use. The faucet has the advantages that the flow adjusting function is independent of the water mixing valve, and the water mixing proportion can be better controlled.
In addition, when the internal fittings of the mixing valve, such as the valve core, need to be replaced due to damage, the existing conventional mixing valve needs to close the home main valve to perform maintenance operation, which causes that other water outlet terminals in the home cannot be used normally. The multifunctional bent feet are only required to be arranged at the two water inlets of the faucet, and when maintenance is needed, the multifunctional bent feet can be closed to replace the water mixing valve, so that the water demand of other places in the home is not influenced.
In summary, the foregoing description is only of the preferred embodiments of the utility model, and is not intended to limit the utility model to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model.
