[0003] With the development of society, tap water can no longer meet people's needs, and direct drinking water has developed rapidly. Direct drinking water undergoes multi-stage filtration to kill viruses and bacteria and filter out discoloration, odor, residual chlorine, ozone, hydrogen sulfide, bacteria, viruses and heavy metals in tap water to obtain directly drinkable water. It is convenient to get water and will not cause waste.

[0004] Direct drinking water is raw water that enters the user end through the water supply pipe after storage and filtration, and then circulates back to the intermediate water tank through the return pipe for circulation. However, since the user's water consumption is changing, the water pressure in the return pipe changes, and there is a problem of poor circulation effect when the water pressure is low. Utility Model Content

[0005] The purpose of the embodiment of the utility model is to provide a direct drinking water supply management system. The utility model controls the circulating water pump through PLC so that the flow pressure of water in the return pipe can be increased at any time, so that the return pipe will not have slow circulation, thereby ensuring the freshness of water quality.

[0006] A direct drinking water supply management system comprises: a water storage tank, a filter part, an intermediate water tank, a water production main unit, a buffer water tank, a finished product water tank, a user end and a return water collector which are connected in sequence, wherein the water outlet of the return water collector is connected to the water inlet of the intermediate water tank via a return water pipe; a flow meter is arranged between the user end and the return water collector, a circulating water pump is arranged on the return water pipe, and the circulating water pump and the flow meter are respectively connected to the PLC controller signal.

[0007] Furthermore, the filtering part includes a multi-media filtering water tank, an activated carbon filtering water tank and a security filtering water tank which are connected in sequence.

[0008] Furthermore, a dosing device is provided between the activated carbon filter water tank and the safety filter water tank.

[0009] Furthermore, a mixer is provided between the water production main unit and the buffer water tank, and an ozone generator is connected above the mixer.

[0010] Furthermore, a manual valve is provided between the user end and the circulating water collector.

[0011] By means of the above scheme, the utility model has at least the following beneficial effects:

[0012] The utility model controls the circulating water pump through PLC so that the flow pressure of water in the return water pipe can be increased at any time, so that the return water pipe will not have a slow circulation situation, thereby ensuring the freshness of water quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to more clearly illustrate the technical solution of the utility model, the following is a brief introduction to the drawings required for describing the embodiments:

[0014] Figure 1 It is a structural schematic diagram of a direct drinking water supply management system in the utility model. DETAILED DESCRIPTION

[0015] The present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the embodiments are intended to make it easier for those skilled in the art to understand the technical solution of the present invention, and cannot be used as a limitation on the protection scope of the present invention.

[0016] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the utility model, and different embodiments can be replaced or combined, so the utility model can also be considered to include all possible combinations of the same and / or different embodiments recorded.

[0023] The utility model controls the circulating water pump through PLC so that the flow pressure of water in the return water pipe can be increased at any time, so that the return water pipe will not have a slow circulation situation, thereby ensuring the freshness of water quality.

[0024] Working principle:

[0025] After the raw water passes through storage and filtration procedures, it enters the user end through the water supply pipe, and then circulates back to the intermediate water tank through the return pipe for circulation. When the circulation effect of the return pipe is not good, the flow meter will detect that the flow value becomes smaller. After reaching the set value, it will be fed back to the PLC. The PLC controls the water pump to force circulation. Of course, set the start time of the circulating water pump and stop automatically after the time is reached.

[0026] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
