[0002] Shower heads are also called shower heads, and are mainly used for showering, shampooing, etc. Shower heads are usually directly connected to water heaters, and can produce both cold and hot water. However, even if the water heater is adjusted to the mode of only producing hot water, cold water will still be produced first when the shower head is turned on because there is cold water stored in the water pipes. Currently, shower head products on the market mainly solve the cold water problem by manually adjusting the temperature and manually draining the cold water section before bathing.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1 -Attached Figure 4 The utility model is further described in detail:

[0025] The utility model discloses a smart shower head with a zero cold water function, such as Figure 1-Figure 3As shown, the utility model is a smart shower with zero cold water function, comprising a shower body 1 and an electrically controlled thermostatic valve 2, and also comprising a first solenoid valve 3 and a water circuit box 4; the shower body 1 is installed at the water outlet of the electrically controlled thermostatic valve 2 through the first solenoid valve 3, and a cold water pipeline, a hot water pipeline and a return water pipeline are arranged inside the water circuit box 4; one end of the cold water pipeline is connected to the cold water source pipe 42 and the cold water inlet pipe of the water heater through a three-way valve 41; one end of the hot water pipeline is connected to the hot water outlet pipe of the water heater, and the other ends of the cold water pipeline and the hot water pipeline are both connected to the electrically controlled thermostatic valve 2; one end of the return water pipeline is connected to the cold water pipeline, and the other end of the return water pipeline is connected to the water outlet of the electrically controlled thermostatic valve 2; in this embodiment, the specific connection method of the cold water pipeline, the hot water pipeline and the return water pipeline is as follows Figure 3 As shown. The cold water source pipe 42 is connected to both the cold water inlet pipe and the return water pipe of the water heater through the three-way valve 41, and can provide cold water from the outside to the water heater and the shower body 1 at the same time. By setting the return water pipe, the cold water pipe, the hot water pipe, the first solenoid valve 3 and the electrically controlled thermostatic valve 2, when the zero cold water mode is not used, the water entering from the cold water source pipe 42 can flow into the electrically controlled thermostatic valve 2 along the cold water pipe and flow out of the shower body 1; when the zero cold water mode is used, the cold water in the hot water pipe can flow from the outlet of the electrically controlled thermostatic valve 2 into the return water pipe, flow into the cold water inlet pipe of the water heater through the cold water pipe and the three-way valve 41, and re-enter the water heater, so that the stored water in the entire pipeline is heated into hot water, which fundamentally solves the problem of the cold water section, so that the user can get hot water by turning on the shower body 1.

[0026] like Figure 1 , Figure 2 As shown, the water outlet of the electric thermostatic valve 2 is threadedly connected with a warm water outlet pipe 43, and the shower body 1 is connected to the warm water outlet pipe 43 through the first solenoid valve 3; in this embodiment, the specific connection position of the warm water outlet pipe 43 is as shown in FIG. Figure 1 As shown, the inner wall of the warm water outlet pipe 43 is provided with an internal thread, the water outlet of the electric-controlled thermostatic valve 2 is provided with an external thread, the water outlet of the electric-controlled thermostatic valve 2 is threadedly connected to one end of the warm water outlet pipe 43, and the other end of the warm water outlet pipe 43 is connected to the shower body 1 through the first solenoid valve 3.

[0027] like Figure 1 , Figure 3 As shown, the cold water pipeline includes a cold water pipe 61; one end of the cold water pipe 61 is connected to the three-way valve 41, and the other end of the cold water pipe 61 is connected to the cold water inlet of the electric-controlled thermostatic valve 2 through a one-way valve; in this embodiment, the specific connection method of the cold water pipe 61 is as follows Figure 3As shown, by providing a cold water pipe 61, the flow between multiple pipes is connected, so that the water outlet mode can be switched between a non-zero cold water mode and a zero cold water mode. A one-way valve (not shown in the figure) is provided at the cold water inlet of the electric-controlled thermostatic valve 2. The one-way valve allows the water in the cold water pipe 61 to flow into the electric-controlled thermostatic valve 2 from the cold water inlet of the electric-controlled thermostatic valve 2 but not to flow out. When using the non-zero cold water mode, the water entering from the cold water source pipe 42 flows into the cold water inlet of the electric-controlled thermostatic valve 2 through the three-way valve 41, and flows out from the shower body 1 from the outlet of the electric-controlled thermostatic valve 2 through the warm water outlet pipe 43 and the first solenoid valve 3.

[0028] like Figure 1 , Figure 3 As shown, the return water pipeline includes a return water pipe 51 and a circulation device 53; one end of the return water pipe 51 is connected to the side wall of the cold water pipe 61 close to the three-way valve 41 through a one-way valve and is communicated with the interior of the cold water pipe 61, and the other end of the return water pipe 51 is connected to the side wall of the warm water outlet pipe 43 and is communicated with the interior of the warm water outlet pipe 43. A circulation device 53 is arranged in the return water pipe 51, and the water flow in the return water pipe 51 can flow into the cold water inlet pipe of the water heater through the cold water pipe 61 and the three-way valve 41; in this embodiment, the flow direction of the one-way valve in the return water pipe 51 is to flow toward the cold water pipe 61. When using the non-zero cold water mode, the water flow from the cold water source pipe 42 will pass through the return water pipe 51 when flowing in the cold water pipe 61. At this time, the water flow is blocked by the one-way valve in the return water pipe 51 and cannot enter the return water pipe 51. By providing the circulation device 53, the cold water in the hot water pipeline can be transported to the return pipe 51, and then re-enter the water heater through the three-way valve 41 and the cold water inlet pipe of the water heater. Preferably, the circulation device 53 is a circulation pump.

[0029] like Figure 2 , Figure 3 As shown, the hot water pipeline includes a hot water pipe 71; one end of the hot water pipe 71 is connected to the hot water outlet pipe of the water heater, and the other end of the hot water pipe 71 is connected to the hot water inlet of the electric-controlled thermostatic valve 2 through a one-way valve; in this embodiment, the specific connection method of the hot water pipe 71 is as follows Figure 3As shown, a one-way valve (not shown in the figure) is provided at the hot water inlet of the electric-controlled thermostatic valve 2. The one-way valve allows the water in the hot water pipe 71 to flow into the electric-controlled thermostatic valve 2 from the hot water inlet of the electric-controlled thermostatic valve 2 but not out. When using the zero cold water mode, the first solenoid valve 3 is closed, the cold water end of the electric-controlled thermostatic valve 2 is closed and the hot water end is opened, the circulation device 53 in the return pipe 51 is started, and the cold water in the hot water pipe 71 can flow into the return pipe 51 along the electric-controlled thermostatic valve 2 and the warm water outlet pipe 43, and flow to the cold water pipe 61 through the one-way valve in the return pipe 51, and re-enter the water heater from the cold water inlet pipe of the water heater through the three-way valve 41 and be heated. At this time, hot water will flow into the hot water pipe 71 from the hot water outlet pipe of the water heater, so that the hot water pipe 71 is filled with hot water again. The electric thermostatic valve 2 is provided with a temperature sensor inside. The temperature of the water flowing out of the water heater can be detected by the temperature sensor inside the electric thermostatic valve 2. When the water temperature reaches a predetermined temperature, zero cold water can be achieved. And because the electric thermostatic valve 2 is closer to the shower body 1, it can quickly detect that hot water has arrived, and the detection result is faster and the water temperature is more accurately detected, preventing excessive hot water from rushing into the cold water pipe 61.

[0030] like Figure 1 , Figure 4 As shown, the electric-controlled thermostatic valve is internally provided with a voice recognition module, a processing module, a display module and a control module;

[0031] A voice recognition module, used to receive the opening and closing instructions issued by the user and send the instructions to the processing module;

[0032] A processing module, used for comprehensively analyzing and processing the instructions sent by the voice recognition module and the real-time temperature data sent by the electronically controlled thermostatic valve, and sending instructions to the control module and the display module;

[0033] A display module is used to display the temperature of water in the electric thermostatic valve and whether the zero cold water mode can be used;

[0034] A control module, used to control the opening and closing of the first solenoid valve and the operation and closing of the circulation device according to the instructions sent by the processing module;

[0035] In this embodiment, the voice recognition module is used to receive user instructions, which include but are not limited to: water use instructions, water stop instructions, and preset temperature adjustment instructions. The voice recognition module will send the received instructions to the processing module for analysis and processing by the processing module.

[0036] The processing module is used to analyze and process the instructions sent by the voice recognition module, and at the same time compare the real-time temperature data sent by the electronically controlled thermostatic valve with the preset temperature;

[0037] When receiving the water use instruction sent by the voice recognition module, the temperature data sent by the electronically controlled thermostatic valve is compared with the preset temperature; if the temperature data sent by the electronically controlled thermostatic valve is the same as the preset temperature, an instruction to open the first solenoid valve and an instruction to close the circulation device are sent to the control module;

[0038] When receiving the water stop command sent by the voice recognition module, a closing command is sent to the electronically controlled thermostatic valve;

[0039] When receiving the instruction for adjusting the preset temperature sent by the voice recognition module, a change instruction is sent to the electric-controlled thermostatic valve to change the preset temperature of the electric-controlled thermostatic valve.

[0040] The display module is used to display the mixed water temperature in the electric-controlled thermostatic valve, and the processing module is used to display the identification of whether the zero cold water mode can be used after comparing the temperature data sent by the electric-controlled thermostatic valve to see whether it reaches the preset temperature.

[0041] The control module is used to send instructions to the first solenoid valve and the circulation device according to the instructions sent by the processing module, so as to open or close the first solenoid valve; and to operate or close the circulation device.

[0042] The implementation principle of the embodiment of the utility model is:

[0043] When using cold water, the first solenoid valve 3 is opened, and water entering from the cold water source pipe 42 flows into the cold water inlet of the electronically controlled thermostatic valve 2 through the three-way valve 41, and flows out of the shower body 1 from the outlet of the electronically controlled thermostatic valve 2 through the warm water outlet pipe 43 and the first solenoid valve 3.

[0044] When using the zero cold water mode, the first solenoid valve 3 is closed, the cold water end of the electric thermostatic valve 2 is closed and the hot water end is opened, the circulation device 53 in the return pipe 51 starts to operate, and the cold water in the hot water pipe 71 can enter the return pipe 51 along the electric thermostatic valve 2 and the warm water outlet pipe 43, and pass through the one-way valve to flow to the three-way valve 41, and re-enter the water heater through the cold water inlet pipe of the water heater to be heated. At the same time, hot water will enter the hot water pipe 71 through the hot water outlet pipe of the water heater, and then flow to the electric thermostatic valve 2. The temperature sensor built into the electric thermostatic valve 2 will send the temperature to the processing module in real time. When the processing module detects that the water temperature reaches the predetermined temperature, the processing module will send instructions to the control module and the display module respectively, and the control module will stop the operation of the circulation device 53; the display module will notify the user that it can be used. When the voice module receives the user's usage instruction, it will send the instruction to the processing module. After analysis and processing, the processing module will send the instruction to the control module. The control module will open the first solenoid valve 3. At this time, the hot water from the water heater in the hot water pipe 71 and the cold water entering from the cold water source pipe 42 are provided for the user to use.

[0045] The following is a description of the principle of water circulation in zero cooling water mode:

[0046] When the first solenoid valve 3 is in a closed state and no water flows in or out of the entire pipeline, the pressures in the water heater, the cold water pipe 61, the hot water pipe 71, the electrically controlled thermostatic valve 2, the circulation device 53, and the return pipe 51 are equal, and are equal to the pressure provided by the water flow in the cold water source pipe 42, so the pressure difference between the above components is zero. When the circulation device 53 is started, a pressure difference is formed at both ends of the circulation device 53, and water will flow in the internal circulation water circuit formed by the above components. Since there is always pressure in the cold water source pipe 42 and water cannot flow back, the cold water in the hot water pipe 71 can be circulated back to the cold water inlet pipe of the water heater through the electrically controlled thermostatic valve 2, the circulation device 53, and the cold water pipe 61, so that the water flow is reheated by the water heater, and the hot water in the water heater enters the hot water pipe 71.

[0047] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field.
