Specifically, in the actual use process, the water pump in the conventional non-negative pressure water supply equipment runs continuously for 24 hours, and when the water consumption of users is greatly reduced at night, the consistent operation of the non-negative pressure water supply equipment will consume a lot of energy. When the user’s water consumption is low, the main water supply pump 12 in the non-negative pressure water supply module 100 is powered off and stops working. At this time, the second electric control valve is opened, the first water pump 22 is powered on, and the main water inlet pipe The water output from 11 is pressurized by the first water pump 22 and delivered to the main water outlet pipe 13 through the second bypass pipe 302, so as to meet the water supply requirements of users in the case of low water consumption.

The utility model also provides a water supply method for the above-mentioned quality-based water supply equipment, including a water quality adjustment water supply mode;

The water quality adjustment water supply mode: when the water quality detected by the second water quality sensor is not up to standard, the water output from the main outlet pipe is first filtered through the pre-filter assembly, and then pressurized by the first water pump and then sent to the main outlet pipe. Specifically, the water in the municipal pipe network is affected by factors such as seasons and the environment. In different periods, the water quality in the municipal pipe network will be different. When the water quality of the municipal pipe network declines, this will lead to a decline in the quality of domestic water for users. In order to ensure that the water quality of the user’s domestic water is maintained at a high level to improve user experience, when the water quality detected by the second water quality sensor is not up to standard during the process of supplying domestic water to the user, part of the water output from the main outlet pipe will pass through the direct The pre-filter components in the drinking water treatment module are treated to obtain higher water quality water sources, and then the treated high-quality water is delivered to the main outlet pipe through the first bypass pipe, so that the user's domestic water can be effectively adjusted. water quality, thereby making the functions of the quality-based water supply equipment of this embodiment diversified and more versatile. Among them, the water quality adjustment water supply mode is specifically: when the water impurities detected by the second water quality sensor exceed the standard, the water output from the main outlet pipe is filtered through a multimedia filter; and/or, when the water detected by the second water quality sensor has a peculiar smell When the color is different, the water output from the main outlet pipe is filtered through an activated carbon filter.

Further, the water supply method also includes an energy-saving water supply mode. In the energy-saving water supply mode, when the total water consumption at the user end is lower than the set value, the main water supply pump stops running, and the water introduced by the main water inlet pipe passes through the second bypass pipe. It is sent to the first water pump, and then pressurized by the first water pump, and then sent to the main outlet pipe through the first bypass pipe. Specifically, in the operation process of the non-negative pressure water supply module, in order to provide sufficient water pressure, the power of the main water supply pump is relatively large, resulting in high power consumption. However, at night, the user's water consumption is very small , at this time, the energy-saving water supply mode starts, the main water supply pump stops running, and the first water pump in the direct drinking water treatment module is used as power to pressurize the water introduced by the main water inlet pipe to the user end, so that the water consumption can be reduced. In this case, the energy consumption of the quality-based water supply equipment in this embodiment can be effectively reduced, and green and low-carbon operation can be realized.

The water supply method of the quality-based water supply equipment provided by the utility model uses the non-negative pressure water supply module to supply water for the user's domestic water and the direct drinking water treatment module at the same time, without the need to separately configure the non-negative pressure water supply module for the direct drinking water function, which will be greatly improved. The installation cost and use cost are reduced, and the space occupied by the whole set of equipment is greatly reduced. At the same time, the second water quality sensor in the main waterway is used to detect the water quality of the water delivered by the non-negative pressure water supply module. When it is detected that the water quality does not meet the requirements At this time, part of the water can be processed by the pre-filter component and then returned to the main outlet pipe for output, so that the water quality of the user's domestic water can be adjusted conveniently, the functions of the water supply equipment can be diversified, and the space occupied by it can be reduced. Installation and usage costs.
