Description

Technical Field

[0001] The utility model relates to the field of faucets, in particular to a multi-position temperature-controlling constant-temperature faucet body. Background Art

[0002] A thermostatic faucet refers to a water control device that uses a thermostatic valve core to achieve constant water temperature, and the faucet body is the main body of the thermostatic faucet, which is equipped with a flow channel inside to transport water. The thermostatic faucet generally has multiple joints, which are used to connect water outlets such as hand-held showerheads, overhead sprays and faucet spouts. The flow channel that flows to the hand-held showerhead, overhead spray or faucet spout is determined by the water diverter valve on the thermostatic faucet to achieve multi-gear control. Since the water diverter valve controls the opening of three water outlets at the same time, the water diverter valve will set its own opening angle to 120 degrees. After rotating 360 degrees, the water diverter valve returns to its original position. If it is in the range of 0 to 120 degrees, the hand-held showerhead, The overhead shower can be opened in the range of 120 degrees to 240 degrees, and the faucet spout can be opened in the range of 240 degrees to 360 degrees. When the faucet spout needs to be opened, the handheld shower and the overhead shower must be opened first. Although the water diverter valve can be rotated in reverse, in actual use, users often confuse the rotation direction of opening the handheld shower, overhead shower or faucet spout. Once the rotation direction is mixed up, even if it is rotated to the actual required position in time, part of the water flow will enter other flow channels that are useless at this time, causing a waste of water flow and resulting in the ineffective use of water resources. In order to avoid incorrect rotation direction, each opening requires careful consideration, which seriously affects the efficiency and experience of use. Summary of the invention

[0019] An upper thickened portion 17 located in front of the cold water joint is provided on the upper surface of the left portion of the faucet body 1; a lower thickened portion 18 located in front of the hot water joint 11 is provided on the lower surface of the left portion of the faucet body 1; the hot water hole 8 is provided on the front side wall of the lower thickened portion 17; the hot water flow channel 10 is provided in the lower thickened portion 17; the cold water hole 7 is provided on the front side wall of the upper thickened portion 18; and the cold water flow channel 9 is provided in the upper thickened portion 18.

[0020] A lower water hole 19 is provided at the rear side of the left end of the hot water flow channel 10; an upper water hole 20 is provided at the rear side of the left end of the cold water flow channel 9; the lower water hole 19 and the upper end of the hot water joint 12 are connected through a lower auxiliary flow channel 21; the upper water hole 20 and the lower end of the cold water joint 11 are connected through an upper auxiliary flow channel 22; the upper auxiliary flow channel 22 and the lower auxiliary flow channel 21 are symmetrical to each other and both are L-shaped; a buffer flow channel 23 is provided at the corner position of the upper auxiliary flow channel 22 and the lower auxiliary flow channel 21; a rear buffer surface 2301 is provided on the inner wall of the rear side of the buffer flow channel 23, and a front buffer surface 2302 is provided on the inner wall of the front side of the buffer flow channel 23; the cross section of the front buffer surface 2302 is wavy; the cross section of the rear buffer surface 2301 is arc-shaped, and one of the wave peaks of the front buffer surface 2302 is opposite to the convex part of the rear buffer surface 2301.

[0021] A positioning groove 24 is provided at the bottom of the water diversion valve installation hole 3; the front end ports of the faucet spout flow channel 15 and the front end ports of the top spray flow channel 16 are both located at the bottom of the positioning groove 24; a positioning hole 25 is provided at the bottom of the positioning groove 24.

[0022] The method of using the utility model is as follows:

[0023] The thermostatic valve core mounting hole 2 can be used to install a thermostatic valve core that matches it, the water diverter valve mounting hole 3 can be used to install a water diverter valve that matches it, the quick-opening valve mounting hole 4 can be used to connect a quick-opening valve that matches it, the top spray joint 14 can be used to connect the top spray, the faucet mouth joint 13 can be used to connect the faucet mouth, the shower joint 6 can be used to connect a handheld shower, and the cold water joint 11 can be used to connect the cold water pipeline, and the hot water joint 12 can be used to connect the hot water pipeline. Before using the thermostatic faucet body 1, plugs can be screwed into the cold water hole 7 and the hot water hole 8 to block and seal the cold water hole 7 and the hot water hole 8.

[0024] The cold water in the cold water pipeline can flow into the thermostatic valve core in the thermostatic valve core installation hole 2 through the cold water connector 11 and the cold water flow channel 9 in sequence, and the hot water in the hot water pipeline can flow into the thermostatic valve core in the thermostatic valve core installation hole 2 through the hot water connector 12 and the hot water flow channel 10 in sequence. As the thermostatic valve core is opened, the cold water and the hot water will be adjusted in the thermostatic valve core to become mixed water with a certain temperature, and enter the mixed water flow channel 5. Finally, the mixed water flow channel 5 is filled with mixed water with the actual required temperature, and the left and right ends of the mixed water flow channel 5 are respectively provided with a water diversion valve and a quick-opening valve. The quick-opening valve can directly open the shower connector 6 to fill the mixed water flow channel 5 with water. The mixed water in 5 is transported to the shower connector 6, and finally sprayed out from the hand-held shower connected to the shower connector 6 for use, and the water diverter valve can control the opening and closing of the top spray or the faucet nozzle by rotating its own valve stem. At this time, the bottom of the water diverter valve mounting hole 3 only has the top spray flow channel 16 and the faucet nozzle flow channel 15, so the water diverter valve can set the rotation angle of opening and closing to 180 degrees. At this time, there is no need to rotate forward or reverse, and the water outlet mode can be switched by rotating more than 180 degrees. If water is discharged from the top spray flow channel 16 at the beginning, when the valve stem of the water diverter valve rotates more than 180 degrees, it will be converted into water discharge from the faucet nozzle flow channel 15, and vice versa.

[0025] From the above, it can be known that the water diverter valve mounting hole 3 of the utility model is only connected with the top spray flow channel 16 and the faucet nozzle flow channel 15, thereby simplifying the structure of controlling three flow channels into a structure of controlling only two flow channels. Therefore, it is only necessary to rotate the valve stem of the water diverter valve installed in the water diverter valve mounting hole 3 to switch one of the flow channels to another flow channel, and there will be no confusion in the conversion between the two flow channels, so that the user can accurately and quickly control the opening and closing of the top spray or the faucet nozzle, and effectively avoid the situation where too many flow channels lead to erroneous opening, thereby causing water resources to be wasted during the erroneous opening process, and the quick-opening valve mounting hole 4 can be used to install the quick-opening valve, so as to independently control the opening and closing of the shower connector 6. The quick-opening valve can use its own quick-opening characteristics to quickly open the handheld shower connected to the shower connector 6, effectively ensuring the use efficiency and user experience.

[0026] An upper thickened portion 17 located in front of the cold water joint is provided on the upper surface of the left part of the faucet body 1, and a lower thickened portion 18 located in front of the hot water joint 11 is provided on the lower surface of the left part of the faucet body 1. The hot water hole 8 is provided on the side wall in front of the lower thickened portion 17, and the hot water flow channel 10 is provided in the lower thickened portion 17. The cold water hole 7 is provided on the side wall in front of the upper thickened portion 18, and the cold water flow channel 9 is provided in the upper thickened portion 18. The existence of the upper thickened portion 17 and the lower thickened portion 18 can locally enlarge the faucet body 1 to avoid the situation where the faucet body 1 is too slender and it is difficult to set the cold water flow channel 9 and the hot water flow channel 10. The hot water joint 12 is further connected to the middle part of the faucet body 1 through the lower thickened portion 18, and the cold water joint 11 is further connected to the middle part of the faucet body 1 through the upper thickened portion 17, which can effectively improve the local strength of the faucet body 1 and facilitate the cold water flow channel 9 and the hot water flow channel 10 to transport water.

[0027] A lower water hole 19 is provided at the rear side of the left end of the hot water flow channel 10, and an upper water hole 20 is provided at the rear side of the left end of the cold water flow channel 9. The lower water hole 19 and the upper end of the hot water joint 12 are connected through a lower auxiliary flow channel 21, and the upper water hole 20 and the lower end of the cold water joint 11 are connected through an upper auxiliary flow channel 22. The upper auxiliary flow channel 22 and the lower auxiliary flow channel 21 are symmetrical to each other and are both L-shaped. A buffer flow channel 23 is provided at the corner position of the upper auxiliary flow channel 22 and the lower auxiliary flow channel 21. A rear buffer surface 2301 is provided on the rear inner wall of the buffer flow channel 23, and a front buffer surface 2302 is provided on the front inner wall of the buffer flow channel 23. The cross section of the front buffer surface 2302 is The cross section of the rear buffer surface 2301 is wavy and arc-shaped. The L-shaped upper auxiliary flow channel 22 and the lower auxiliary flow channel 21 can prevent the straight flow of water from causing excessive impact force and noise. When one of the wave peaks of the front buffer surface 2302 is opposite to the raised part of the rear buffer surface 2301, the buffer flow channel 23 can be gradually narrowed, thereby further buffering the water flow pressure. The wavy front buffer surface 2302 can make the water flow fluctuate, thereby minimizing the water flow pressure and noise. At the same time, it can effectively prevent the straight flow of water from long-term impact on the thermostatic valve core in the thermostatic valve core mounting hole 2, causing the thermostatic valve core to be easily damaged.

[0028] A positioning groove 24 is provided at the bottom of the water diverter valve mounting hole 3, and the front end ports of the faucet nozzle flow channel 15 and the top spray flow channel 16 are both located at the bottom of the positioning groove 24. A positioning hole 25 is provided at the bottom of the positioning groove 24. The presence of the positioning groove 24 can effectively position the lower end of the water diverter valve installed in the water diverter valve mounting hole 3, thereby ensuring the stability of the water diverter valve when installed in the water diverter valve mounting hole, and the presence of the positioning hole 25 can further position the lower end of the water diverter valve, ensuring that the water delivery hole on the lower end face of the water diverter valve can be accurately aligned with the front end ports of the top spray flow channel 16 and the front end ports of the faucet nozzle flow channel 15, so as to facilitate the water diverter valve to accurately control the opening and closing of the top spray flow channel 16 or the faucet nozzle flow channel 15.
