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. However, in the case of low water consumption of the intelligent non-negative pressure water supply equipment in this embodiment, 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 energized to run, and the water output from the main water inlet pipe 11 is pressurized by the first water pump 22 and then sent to the main water outlet pipe 13 through the second bypass pipe 302, so as to meet the water supply of users in the case of low water consumption.

Compared with the direct drinking water equipment in the prior art that directly discharges waste water, the intelligent water quality control non-negative pressure water supply equipment in this embodiment can maximize the use of water resources, reduce waste, and achieve environmental protection.

The utility model also provides a water supply method for the above-mentioned intelligent non-negative pressure and quality water supply equipment, including a conventional water supply mode, a direct drinking water supply mode and a water quality adjustment water supply mode;

The normal water supply mode: the water output from the main outlet pipe is directly supplied to the user end. Specifically, the conventional water supply mode is the same as the usual non-negative pressure water supply equipment for water supply, that is, the non-negative pressure water supply equipment is used to pressurize the water in the municipal pipe network to each household for use.

The direct drinking water supply mode: the water output from the main water outlet pipe is sequentially processed by the pre-filtration module and the reverse osmosis membrane module, and the direct drinking water obtained is supplied to the user end. Specifically, the water output from the non-negative pressure water supply module enters the direct drinking water treatment module through the main water outlet pipe, and the water is treated by the pre-filtration module and the reverse osmosis membrane module to obtain direct drinking water and supply it to users.

The water supply mode for water quality adjustment: in the normal water supply mode, when the water quality detected by the first water quality sensor is not up to the 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 passed through the first water pump. A bypass pipe is 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, in the normal water supply mode, when the water quality detected by the first water quality sensor is not up to standard, part of the water output from the main outlet pipe will pass through the direct drinking water treatment module The pre-filter components in the middle of the system are treated to obtain a higher water quality water source, and then the treated high-quality water is delivered to the main outlet pipe through the first bypass pipe, so that the water quality of the user's domestic water can be effectively adjusted, thereby This makes the intelligent non-negative pressure water supply equipment of this embodiment diversified in function and stronger in versatility. Among them, the water quality adjustment water supply mode is specifically: when the water impurities detected by the first 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 first 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; and/or, when the hardness or heavy metal content of the water detected by the first water quality sensor exceeds the standard, the water output from the main outlet pipe is filtered through a water softener.

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 12 is relatively large, resulting in large power consumption. However, at night, the water consumption of users is very high. At this time, the energy-saving water supply mode starts, the main water supply pump stops, and the first water pump in the direct drinking water treatment module is used as the 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 the case of less, the energy consumption of the intelligent non-negative pressure water supply equipment of this embodiment can be effectively reduced, and green and low-carbon operation can be realized.

Compared with the prior art, the advantages and positive effects of the utility model are: the intelligent non-negative pressure water supply equipment provided by the utility model can simultaneously supply water to the user's domestic water and direct drinking water treatment module by using the non-negative pressure water supply module , instead of configuring a non-negative pressure water supply module for the direct drinking water function, which will greatly reduce the installation cost and use cost, and at the same time greatly reduce the space occupied by the whole set of equipment. At the same time, the first water quality sensor in the main waterway is used to detect no The water quality of the water delivered by the negative pressure water supply module, when it is detected that the water quality does not meet the requirements, 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 easily adjusted to achieve The intelligent non-negative pressure water supply equipment has multiple functions, reduces the space it occupies, and reduces the cost of installation and use.
