the power generation module 1 comprises a main pipeline 11, a branch pipeline 12, a water flow generator 13 and a check valve 14, wherein the water flow generator 13 is arranged on the main pipeline 11, the check valve 14 is arranged on the branch pipeline 12, a water inlet end of the main pipeline 11 is communicated with a water inlet end of the branch pipeline 12, and the opening pressure of the check valve 14 is greater than the minimum working pressure of the water flow generator 13 and less than the maximum working pressure of the water flow generator 13;
the current input end of the storage battery 7 is electrically connected with the current output end 23 of the water flow generator 13;
the electric water mixing valve 2 is provided with a hot water end 21, a cold water end 22 and an output end 23, wherein the hot water end 21 is connected with an external hot water source, and the cold water end 22 is connected with an external cold water source; the output end 23 is communicated with the water inlet end of the main pipeline 11 and the water inlet end of the branch pipeline 12;

the control circuit board 6 is electrically connected with the storage battery 7, and the electric water mixing valve 2, the electric flow valve 3, the electric shunt valve 4 and the temperature sensor 5 are respectively electrically connected with the control circuit board 6.
The traditional power generation module 1 is a single passage, and the water flow generator 13 is directly connected with an external water source, so that the water pressure of the external water source is all applied to the water flow generator 13 of the power generation module 1, whether the water flow power generation module 1 can normally work completely depends on whether the water pressure of the external water source is in the working water pressure range of the water flow generator 13, the working water pressure range refers to the water pressure range capable of driving the water flow generator 13 to normally work, namely the range between the lowest water pressure capable of starting the water flow generator 13 and the highest water pressure capable of enabling the water flow generator 13 to normally work and not to slip and lose efficacy, the traditional power generation module 1 has a narrow working water pressure range, so that different working environments are difficult to meet, and the normal work of the power generation module 1 is possibly influenced by too high or too; at present, the conventional solution is to use the water flow generator 13 with a wider working water pressure range, but since the working water pressure range of the water flow generator 13 is wider, the price thereof is greatly increased, and since if the water flow generator 13 with a wider working water pressure range is used, the problem of higher cost undoubtedly exists, and it is difficult to satisfy the market demand of each level. The lowest starting water pressure of the water flow generator 13 can be configured to be lower than or close to the lowest water pressure standard of urban tap water, so that the water flow generator 13 can work normally under the lower water pressure environment; the power generation module 1 is provided with the check valve 14 and the branch pipeline 12, and the branch pipeline 12 and the check valve 14 can perform a pressure relief effect on the main pipeline 11 in an environment with higher water pressure, so that the water pressure of the main pipeline 11 can be always kept in a working water pressure range of the water flow generator 13 in the power generation module 1 in the environment with higher water pressure; since the opening pressure of the check valve 14 is between the minimum working pressure and the maximum working pressure of the water flow generator 13, of course, the opening pressure of the check valve 14 can be close to the maximum working pressure of the water flow generator 13, and when the water pressure of the external water source is higher than the minimum working pressure of the water flow generator 13 and lower than the opening pressure of the check valve 14, the check valve 14 is in a closed state, as shown in fig. 1, so that the water pressure of the main pipeline 11 can be ensured in a low-pressure environment, the water pressure of the main pipeline 11 is equal to the water pressure of the external water source, and the water flow generator 13 normally generates electricity; when the water pressure of the external water source is higher than the opening pressure of the check valve 14, the check valve 14 is conducted under the action of the water pressure, as shown in fig. 2, the external water source is conducted from the main pipeline 11 and the branch pipeline 12 respectively, and part of the water pressure is distributed to the branch pipeline 12, by this way, the check valve 14 and the branch pipeline 12 can effectively decompress the main pipeline 11 in the environment with higher water pressure, so that the water pressure arranged in the main pipeline 11 is kept in the working water pressure range of the water flow generator 13, and the working water pressure range of the power generation module 1 is increased on the basis of not changing the parameters of the water flow generator 13, thereby effectively solving the problem that the traditional power generation module 1 cannot meet various water pressure environments due to the narrower working water pressure range; in addition, the branch pipe 12 and the check valve 14 have a low cost and a simple structure, and thus the power generation module 1 of the present application also has an advantage of low cost.
When the electric water mixing valve is used, the electric water mixing valve 2 is opened by the electric energy provided by the storage battery 7, at the moment, the electric water mixing valve 2, the power generation module 1 and the electric water distribution valve 4 form a passage, an external hot water source and a cold water source respectively enter the electric water mixing valve 2 through the hot water end 21 and the cold water end 22 and are mixed and converged in the electric water mixing valve 2, the mixed water drives the power generation module 1 to work when flowing through the power generation module 1, and the electric energy generated by the power generation module 1 during working flows to the storage battery 7 to charge the storage battery 7; the water flowing out of the power generation module 1 enters the electric shunt valve 4 and is output to the outside from the electric shunt valve 4 for users to use; when the water temperature needs to be adjusted, the mixing ratio of the hot water and the cold water is adjusted by controlling the electric water mixing valve 2, so that the water temperature is adjusted; the electric flow valve 3 can stably adjust the water flow entering the electric shunt valve 4, when the water pressure fluctuates, the water outlet end of the electric shunt valve 4 can also keep stable water outlet flow, and the user experience is better; in addition, the temperature sensor 5 is arranged at the water outlet end of the electric water mixing valve 2, when cold water and hot water are mixed in the electric water mixing valve 2 and then are output from the electric water mixing valve 2, the temperature sensor 5 can detect the temperature of warm water output by the electric water mixing valve 2 and immediately feed back a detected signal to the control circuit board 6, and the control circuit board 6 compares the signal of the temperature sensor 5 with a target temperature to further adjust the proportion of cold water and hot water in the electric water mixing valve 2, so that the temperature of the warm water output by the electric water mixing valve 2 is closer to the target temperature; because the temperature sensor 5 is disposed at the output end 23 of the electric mixing valve 2, the temperature detected by the temperature sensor 5 is the temperature of the current electric mixing valve 2 after mixing cold water and hot water, the present invention has a smaller hysteresis than the temperature sensor 5 disposed at the output end 23 of the electric mixing valve 2 disposed at the water outlet 42, because when the mixing ratio of cold water and hot water of the electric mixing valve 2 is changed, a certain time is required for warm water to flow from the output end 23 of the electric mixing valve 2 to the water outlet 42, and during this process, the temperature at the water outlet 42 is still the temperature before the mixing ratio of cold water and hot water of the electric mixing valve 2 is changed, so the temperature sensor 5 disposed at the water outlet 42 has a larger hysteresis, and the present invention innovatively disposes the temperature sensor 5 at the output end 23 of the electric mixing valve 2, therefore, the water temperature of the electric water mixing valve after water mixing can be detected in real time, the temperature can be adjusted more accurately, and the temperature adjusting speed is higher; when the water temperature changes due to unstable water pressure, the temperature sensor 5 can detect the fluctuation of the water temperature at the first time, so that the temperature signal is fed back to the control circuit board 6, and the control circuit board 6 controls the mixing proportion of the cold water and the hot water of the electric water mixing valve 2, so that the water temperature is kept at the target temperature, and the water temperature is kept stable better.
