After the mounting of the detachable domestic water-saving circulating device is completed, the lower end of the third hot water pipe 1 is communicated with the right end of the first hot water pipe 19, the lower end of the third cold water pipe 13 is communicated with the right end of the first cold water pipe 20, the right end of the cold water outlet pipe 17 is communicated with the left end of the second cold water pipe, and the right end of the hot water outlet pipe 18 is communicated with the left end of the second hot water pipe.
The basic waterway flow direction of the detachable household water-saving circulation assembly is as follows:
cold water is introduced into the left end of the cold water main pipe 12 and is shunted to a fourth cold water pipe 14 and a third cold water pipe 13 through a third three-way pipe 15, the fourth cold water pipe 14 conveys cold water to a water heater 23, the cold water is heated in the water heater 23 to become hot water, and the hot water is conveyed to a hot water channel of the switching type water faucet 16 through a third hot water pipe 1, a first hot water pipe 19, a second hot water pipe and a hot water outlet pipe 18 in sequence, and when the switching type water faucet 16 is switched to a hot water gear, the hot water can flow out. Similarly, the cold water in the third cold water pipe 13 is sequentially conveyed to the cold water channel of the switching faucet 16 through the first cold water pipe 20, the second cold water pipe and the cold water outlet pipe 17, and when the switching faucet 16 is driven to a cold water level, the cold water can flow out.
After the switching type water faucet 16 is used for a period of time in a non-hot water gear, hot water in the third hot water pipe 1, the first hot water pipe 19, the second hot water pipe and the hot water outlet pipe 18 gradually becomes cool, at the moment, the switching type water faucet 16 is switched to a hot water gear immediately, and cold water or warm water flows out, so that the living needs cannot be met, and waste is caused.
For this reason, domestic water conservation circulating device of reassembling type still includes check valve 4, circulating pump 3, control panel 5, pressure switch 8, No. one three-way pipe 21 and No. two three-way pipe 22 in this embodiment, and No. one three-way pipe 21, No. two three-way pipe 22, check valve 4, circulating pump 3, control panel 5 and pressure switch 8 all set up in casing 24 to in the lump dismouting along with casing 24.

Meanwhile, the lower end of the second three-way pipe 22 and the upper end of the first three-way pipe 21 are communicated through the check valve 4, so that warm water or cold water in the third hot water pipe 1 and the first hot water pipe 19 can flow to the first cold water pipe 20 or the second cold water pipe in a one-way mode when the check valve 4 is opened, and the warm water or the cold water and original cold water in the first cold water pipe 20 or the second cold water pipe are mixed and used as cold water, or flow back to the water heater 23 for heating. The hot water heater 23 regenerates new hot water to flow to the first hot water pipe 19 via the third hot water pipe 1 for supplement, and then closes the check valve 4, so that the first hot water pipe 19 can deliver the hot water to the switching faucet 16 again. Since at least a part of the warm water or the cold water in the third hot water pipe 1 and the first hot water pipe 19 will flow to the second cold water pipe when the switching type water tap 16 is switched to the hot water range, the whole warm water or the cold water actually flowing out when the switching type water tap 16 is switched to the hot water range only has the warm water or the cold water in the second hot water pipe and the hot water outlet pipe 18, and a small amount of the cold water and the warm water in the first hot water pipe 19 and the third hot water pipe 1 which do not flow to the check valve 4.
Therefore, the amount of warm or cold water flowing out from the switching faucet 16 immediately after switching to the hot water range can be reduced by increasing the flow rate of the check valve 4 as much as possible, and the circulation pump 3 is installed at the check valve 4, so that the flow rate of warm or cold water inside the check valve 4 is increased when the check valve 4 is turned on.
