[0012] The return pipe is connected to one side of the water outlet end of the cold water inlet pipe, and the return pipe is connected in parallel to the water outlet end of the water pump through a corresponding return solenoid valve.

[0017] The outer wall of the sleeve is fixedly connected with a plurality of reinforcing ribs whose outer ends abut against the inner walls of the hot water inlet pipe and the cold water inlet pipe, and the outer wall of the guide shaft is fixedly connected with a group of guide protrusions whose outer ends are slidably mounted on the inner wall of the sleeve.

[0018] The inner ends of the guide shafts are respectively provided with corresponding inner grooves, and the depths of the inner grooves are gradually increased.

[0022] Advantages of the utility model:

[0023] 1) During use, the utility model can detect the temperature of water in the circulation process through the water inlet temperature sensor. When the temperature value detected by the water inlet temperature sensor is less than the set value, the mixing water solenoid valve and the water outlet solenoid valve are closed, the return water solenoid valve is opened, and the water pump is started to pump out the hot water in the water heater, so that the hot water flows along the hot water inlet pipe, the water pump, the return water pipe, and the cold water inlet pipe, so that the cold water in the pipeline outside the water inlet temperature sensor flows back to the water tank of the water heater; until the temperature value detected by the water inlet temperature sensor is not less than the set value, the mixing water solenoid valve, the water outlet solenoid valve are opened, and the return water solenoid valve is closed, so that the hot water in the water heater and the cold water entering the tap water inlet pipe are mixed and pumped out to the mixing water outlet pipe for discharge and use.

[0024] Therefore, on the basis of the original adjustment of water temperature and water volume, the cold water stored in the pipe between the water heater and the water mixer can be easily refluxed for utilization, so as to improve the utilization rate of water resources.

[0025] 2) When the flow regulating assembly of the utility model is performing flow regulation, the stepping motor is mainly used to drive the driving shaft to rotate, so as to drive the guide shaft to form a directional movement, thereby adjusting the water flow throttling area between the inner end of the guide shaft and the fixed annular member to achieve flow regulation.

[0026] 3) The utility model further integrates the corresponding sleeve on the cover plate and sets it inward. The sleeve and the guide shaft, the hot water inlet pipe, and the cold water inlet pipe are set at intervals, and the sleeve is provided with a water inlet hole. The outer wall of the sleeve is fixed with a plurality of reinforcing ribs whose outer ends abut against the inner walls of the hot water inlet pipe and the cold water inlet pipe. The outer wall of the guide shaft is fixed with a group of guide convex edges whose outer ends are slidably mounted on the inner wall of the sleeve. During the circulation of water, it first enters between the sleeve and the hot water inlet pipe and the cold water inlet pipe, then enters between the sleeve and the guide shaft through the water inlet hole, and then enters into the hot water inlet pipe and the cold water inlet pipe through the guide shaft and the fixed annular member to circulate, so it will not affect the normal circulation of the water. By setting the shaft sleeve, on the one hand, it can divert the circulating water to reduce the impact of continuous changes in water pressure on the guide shaft; on the other hand, it can cooperate with the reinforcing rib plate and the guide ridge to form a more stable guide support for the guide shaft, so as to ensure the assembly and operation stability of the guide shaft that plays a flow regulating role. This is undoubtedly of great significance for the flow regulating components that need to be in operation for a long time.

[0027] 4) The second clamping platforms of the hot water inlet pipe and the cold water inlet pipe of the utility model are respectively clamped with corresponding hollow abutment parts, and the outer ends of the hollow abutment parts are respectively fixedly buckled to the inner ends of the fixed annular parts. Under the premise of not affecting the flow of water, the assembly stability of the fixed annular parts is improved, thereby further improving the overall assembly and operation stability of the flow regulating assembly.

[0028] 5) The utility model has corresponding water flow buffer components fixedly installed on the hot water inlet pipe and the cold water inlet pipe between the flow sensor and the second clamping platform, respectively. The planar diverter plate of the water flow buffer component is used to divert the circulating water. The water after diversion forms a flow buffer under the guidance of the spiral diverter plate, so as to reduce the impact of the continuous change of water pressure on the flow sensor.

[0038] refer to Figure 1-8 , an electronic water mixer, comprising

[0039] A housing 1, on which a hot water inlet pipe 2 and a cold water inlet pipe 3 are installed;

[0040] A water mixing solenoid valve 4 is used to form a switchable connection between the outlet ends of the hot water inlet pipe 2 and the cold water inlet pipe 3;

[0041] A mixing water pipe 5 is connected to one side of the water outlet end of the hot water inlet pipe 2. The end of the mixing water pipe 5 not connected to the hot water inlet pipe 2 is connected to a corresponding water pump 6. The water outlet end of the water pump 6 is connected in parallel to a plurality of mixing water outlet pipes 8 equipped with water outlet solenoid valves 7.

[0044] During use, the water temperature in the circulation process can be detected by the water inlet temperature sensor 9. When the temperature value detected by the water inlet temperature sensor 9 is less than the set value, the mixing water solenoid valve 4 and the water outlet solenoid valve 7 are closed, the return water solenoid valve 11 is opened, and the pump 6 is started to pump out the hot water in the water heater, so that the hot water flows along the hot water inlet pipe 2, the pump 6, the return water pipe 10, and the cold water inlet pipe 3, so that the cold water in the pipeline outside the water inlet temperature sensor 9 flows back to the water tank of the water heater; until the temperature value detected by the water inlet temperature sensor 9 is not less than the set value, the mixing water solenoid valve 4 and the water outlet solenoid valve 7 are opened, and the return water solenoid valve 11 is closed, so that the hot water in the water heater and the cold water entering the tap water inlet pipe are mixed and pumped out to the mixing water outlet pipe 8 for discharge and use.

[0045] The water inlet ends of the hot water inlet pipe 2, the cold water inlet pipe 3, and the water outlet end of the mixed water outlet pipe 8 are respectively arranged at the bottom of the shell 1, and a corresponding water outlet temperature sensor (not marked) is fixedly installed on the mixed water outlet pipe 8.

[0046] The hot water inlet pipe 2 and the cold water inlet pipe 3 are respectively fixed with flow regulating components 12 for regulating water flow. The hot water inlet pipe 2 and the cold water inlet pipe 3 are respectively arranged in an L shape, and corresponding communication holes are respectively opened at the folded parts of the hot water inlet pipe 2 and the cold water inlet pipe 3, and corresponding cover plates 13 are respectively sealed and installed at the communication holes. The hot water inlet pipe 2 and the cold water inlet pipe 3 inside the communication holes are respectively provided with corresponding first clamping platforms 14, and the flow regulating component 12 includes a fixed annular member 1201 clamped on the first clamping platform 14, and a corresponding guide shaft 1202 is movably provided in the middle of the fixed annular member 1201, and the inner end diameter of the guide shaft 1202 is gradually reduced from the outside to the inside, and the guide shaft 1202 is movably connected to the corresponding drive shaft 1203 by threaded connection, and the drive shaft 1203 is transmission-connected to the output shaft end of the corresponding stepping motor 15.

[0047] When the flow rate is adjusted, the driving shaft 1203 is mainly driven to rotate by the stepping motor 15 to drive the guide shaft 1202 to form a directional movement, thereby adjusting the water flow throttling area between the inner end of the guide shaft 1202 and the fixed annular member 1201 to achieve flow rate adjustment.

[0048] The cover plate 13 is integrally formed and has a shaft sleeve 16 inwardly arranged to be pressed against the fixed annular member 1201 . The shaft sleeve 16 is spaced apart from the guide shaft 1202 , the hot water inlet pipe 2 , and the cold water inlet pipe 3 , and a corresponding water inlet hole 1601 is arranged on the shaft sleeve 16 .

[0049] The outer wall of the sleeve 16 is fixedly connected with a plurality of reinforcing ribs 1602 whose outer ends abut against the inner walls of the hot water inlet pipe 2 and the cold water inlet pipe 3. The outer wall of the guide shaft 1202 is fixedly connected with a group of guide protrusions 17 whose outer ends are slidably mounted on the inner wall of the sleeve 16.

[0050] During the water flow, it first enters between the sleeve 16 and the hot water inlet pipe 2 and the cold water inlet pipe 3, then enters between the sleeve 16 and the guide shaft 1202 through the water inlet hole 1601, and then enters the hot water inlet pipe 2 and the cold water inlet pipe 3 through the guide shaft 1202 and the fixed annular member 1201 to circulate, so it will not affect the normal flow of the water. The sleeve 16 can be set up to divert the circulating water to reduce the impact of the continuous change of water pressure on the guide shaft 1202; secondly, it can cooperate with the reinforcing rib plate 1602 and the guide convex edge 17 to form a more stable guide support for the guide shaft 1202, so as to ensure the assembly and operation stability of the guide shaft 1202 that plays a role in flow regulation.

[0053] By providing the hollow abutment member 20 , the assembly stability of the fixed annular member 1201 is improved without affecting the circulation of water, thereby further improving the overall assembly and operation stability of the flow regulating assembly 12 .

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
