[0014] The following is a further detailed description through specific implementation methods:

[0015] like Figures 1 to 3 As shown:

[0016] A constant temperature and constant pressure water supply system, comprising two groups of water supply modules 1 and one group of water mixing modules 2 with the same structure, wherein the two groups of water supply systems are respectively a hot water supply system and a cold water supply system, and are respectively used to provide hot water and cold water; the two groups of water supply modules 1 are connected to the water mixing modules 2, and the water mixing modules 2 can fully mix cold water and hot water;

[0017] The water supply module includes a water storage tank 11, a first water pump 12, a buffer water tank 13, a water supply pipe 14 and a constant pressure water supply mechanism. The water storage tank 11 is used to store water in advance. The first water pump 12 is used to pump the water in the water storage tank 11 into the buffer water tank 13. Since the power of the first water pump 12 is constant, the first water pump 12 can input water into the buffer water tank 13 at a constant pressure. The constant pressure water supply mechanism in the buffer water tank 13 can buffer and relieve the water pumped into the buffer water tank 13 by the first water pump 12 to avoid fluctuations in the outlet pressure of the buffer water tank 13. The constant pressure water supply mechanism includes a mesh plate 15, a sponge pad 16 and The sintered plate 17, the mesh plate 15, the sponge pad 16 and the sintered plate 17 are fixedly installed in the buffer water tank 13 from top to bottom. The mesh plate can initially block the pumped water of the first water pump 12 to prevent the water pumped into the buffer tank by the first water pump 12 from directly impacting the interior of the buffer water tank 13. The sponge pad 16 can further buffer the incoming water. The sintered plate 17 is densely covered with small through holes, which can evenly distribute the water in the upper space of the buffer water tank 13 to the lower space of the buffer water tank 13, thereby reducing the water pressure fluctuation in the lower space of the buffer water tank 13. The water supply pipe 14 is used to transport the water in the lower part of the buffer water tank 13 to the mixing water module 2.

[0018] The mixing water module 2 includes a mixing water tank 21, a second water pump 22 and a mixing water box 24. The mixing water box 24 is installed in the inner upper space of the mixing water tank 21. A plurality of water outlet holes 25 are evenly opened on the upper side of the mixing water box 24. The water supply pipe 14 is connected to the bottom of the mixing water box 24, so that the water in the buffer water tank can enter the mixing water box 24 from the bottom of the mixing water box 24. The two water supply modules 1 respectively input cold water and hot water into the mixing water box 24, so that the cold water and hot water are initially mixed evenly in the mixing water box 24, and then flow from the water outlet holes 25 at the mixing water box 24 into the mixing water tank 21 for secondary mixing, and finally the mixed water is pumped out from the lower part of the mixing water box 24 by the second water pump 22 through the pumping pipe 23.

[0019] The specific implementation process is as follows:

[0020] When using the present constant temperature and constant pressure water supply system, firstly, pre-store cold water and hot water in the two water storage tanks 11 respectively, that is, when the two water storage tanks 11 are connected to an external water supply, the water supply to the buffer water tank is suspended; when the system needs to be used for water supply, the first water pump 12 is started, and the first water pump 12 pumps the water in the water storage tank 11 to the buffer water tank 13, and the water enters from the top of the buffer water tank 13 and is sprayed to the mesh plate 15. The mesh plate 15 performs preliminary pressure relief and interception on the water flow, and then enters from the mesh holes of the mesh plate 15 into the sponge pad 16. After further blocking and pressure relief by the sponge pad 16, the water flow pressure entering the range of the sponge pad 16 is relatively stable, and the best Finally, it enters the lower space of the buffer water tank 13 from the sintered plate 17 which is densely covered with small holes. The sintered plate 17 can evenly input the water flow into the lower space of the buffer water tank 13 to avoid fluctuations in water flow and water pressure. When the second motor is started, the water in the two buffer water tanks 13 respectively filled with cold water and hot water enters the mixing tank 24 from the water supply pipe 14, so that the cold water and hot water are initially mixed evenly in the mixing tank 24, and then flow from the water outlet 25 at the mixing tank 24 to the mixing tank 21 for secondary mixing, and finally the mixed water is pumped out from the lower part of the mixing tank 24 by the second water pump 22 through the pumping pipe 23, so that the outlet water temperature and pressure at the waterfall pump are relatively constant.

[0021] This constant temperature and constant pressure water supply system is connected to cold water and hot water respectively through two groups of water supply modules 1. The cold water and hot water processed by the water supply module 1 can be input into the mixing water module 2 at a relatively constant pressure and stably. The mixing water module 2 can fully mix the cold water and hot water and then discharge them, so that the outlet water temperature processed by the mixing water module 2 is relatively constant. This system can effectively reduce the problem of unstable system water supply pressure and temperature caused by water inlet pressure fluctuations and unbalanced water mixing, so that the water supply pressure and temperature processed by this system are more stable, meeting the user's usage needs.
