Description

Household water purifying and drinking machine with water inlet pressure stabilizing device

Technical Field

The utility model relates to the technical field of water purification equipment manufacturing, in particular to a household water purifying and drinking machine with a water inlet pressure stabilizing device.

Background

Due to the continuous development of industrial technology and the continuous improvement of living standard, the phenomenon that water sources in cities are polluted is more and more serious, and the health of people is adversely affected. On the other hand, with the demands of people on life quality and the importance of self health conditions, the problem of water quality of domestic water is getting more and more attention. Under such a background, the household water purifying and drinking machine has wide market space, can perform multistage treatment and deep purification on municipal tap water, and provides high-quality and convenient drinking water experience for users.

The water inlet pressure is an important parameter of the household water purifying machine, and reasonable setting of the water inlet pressure plays an indispensable role in maintaining the normal operation of the water purifying machine, and the water inlet pressure is preferably 0.1Mpa-0.4 Mpa. However, it is not negligible that the domestic water purifying machine often has a situation that the water inlet pressure changes rapidly in a short time in the actual use process, such as a huge pressure generated by a water hammer phenomenon generated in a pipeline when the tap is closed rapidly, a water pressure generated by suddenly increasing the water inlet pressure at the moment of opening the total water valve, a water pressure impact force generated when the tap is opened after a period of water cut-off, etc. The instantaneous increase of water pressure not only can damage the purification effect and service life of various filter elements, filter flask fittings and membranes in the filtering device, but also can cause water leakage of the pipeline of the water purifying drinking machine. The household water purifying machine has the advantages of reducing the service life of the household water purifying machine, improving the use cost, even causing the occurrence of safety accidents such as pipe explosion and the like, and being a troublesome problem in the popularization and use process of the household water purifying machine, and always puzzles manufacturers and consumers.

In order to prevent adverse effects caused by the increase of the water inlet pressure, conventional water purifying apparatuses generally employ a measure of reducing the water inlet pressure by adding a pressure reducing valve, but there is a limit to this measure because the measure does not have a water inlet pressure regulating function when coping with instantaneous variable tap water inlet pressure which may exist in the environment. Once the pressure of the water inlet water is too small after the pressure is reduced, the water cannot flow into the water purifying and drinking machine in time, and the water yield of the equipment is reduced, so that the water yield is influenced. In summary, a reasonable hydraulic buffer range is necessary for the household water purifying and drinking machine.

The devices listed in the figures are simplified schematic views illustrating the basic water purification process of the present utility model by way of illustration only, and therefore show only the structures relevant to the present utility model.

Example 1

As shown in fig. 1 to 3, the household water purifying and drinking machine with the water inlet pressure stabilizing device of this embodiment includes: a water inlet 1, a first electromagnetic valve 2, a pressure stabilizing system 3, a pretreatment system 4, a booster pump 5, a second electromagnetic valve 6, a reverse osmosis membrane filtration system 7, a high-voltage switch 8, a water purification pressure barrel 9, a rear antibacterial filter element system 10, a rear ultraviolet sterilization system 11, a water purification outlet 12, a reflux ratio 13, a concentrated water outlet 14 and a PLC control system 15; the water inlet 1 is connected with municipal tap water; the pretreatment system 4 is sequentially connected with three groups of filtering equipment, and the three groups of filtering equipment respectively adopt a PP melt-blown filter element, a granular activated carbon core and a compressed activated carbon filter element for filtering.

The main body of the pressure stabilizing system comprises a protective shell 3-1, a pressure stabilizing telescopic bag 3-2, a pressure sensor 3-3, a water level sensor 3-4 and an audible and visual alarm device 3-5. The water inlet end of the pressure stabilizing system 3 is connected with the water inlet 1 through the first electromagnetic valve 2, and the water outlet end is connected with the water inlet end of the pretreatment system 4. The protective housing 3-1 main part adopts 304 stainless steel, steady voltage flexible bag 3-2 adopts the PVC material. The pressure stabilizing telescopic bag 3-2 is internally provided with a pressure sensor 3-3 and a water level sensor 3-4. The data signal output ends of the pressure sensor 3-3 and the water level sensor 3-4 are electrically connected with the signal input end of the audible and visual alarm device 3-5. The PLC control system 15 is electrically connected with the first electromagnetic valve 2, the audible and visual alarm device 3-5, the second electromagnetic valve 6 and the high-voltage switch 8.

A more detailed explanation is:

when the utility model is put into use, the water pressure threshold value a and the water level threshold value b of the pressure stabilizing system 3 are determined in advance according to the pressure bearing capacity of the pressure stabilizing telescopic bag 3-2 and the height of the protective shell 3-1. The function of buffering and adjusting the water inlet pressure is achieved through the contraction (shown in figure 2) and the expansion (shown in figure 3) of the pressure stabilizing telescopic bag 3-2. Meanwhile, the protective shell 3-1 on the outer layer of the pressure-stabilizing telescopic bag has the function of explosion prevention and water leakage prevention, and the dangerous situation of expansion and breaking caused by overlarge water inlet pressure can be avoided. When the pressure sensor 3-3 detects that the pressure in the pressure stabilizing and telescoping bag 3-2 is greater than a, or when the water level sensor 3-4 detects that the water level in the pressure stabilizing and telescoping bag 3-2 is higher than b, the pressure stabilizing and telescoping bag 3-2 expands, and the pressure stabilizing system 3 is in the state shown in fig. 3. At this time, the PLC control system 15 determines that the water inlet pressure is abnormal, controls the audible and visual alarm device 3-5 to start, and sounds and lights to remind the user. Simultaneously, the electromagnetic valve I2, the electromagnetic valve II 6 and the high-voltage switch 8 are automatically closed, damage to a pipeline of the water purifying machine and a water purifying part is avoided, and related pressure data is synchronously uploaded to the cloud end, so that multiple departments such as a maintenance part, an engineering part and municipal tap water supply share data in real time, and timely maintenance and reasonable planning of the water inlet pressure of subsequent municipal tap water are facilitated. When the pressure sensor 3-3 detects that the pressure in the pressure stabilizing telescopic bag 3-2 is smaller than or equal to a, and when the water level sensor 3-4 detects that the water level in the pressure stabilizing telescopic bag 3-2 is smaller than or equal to b, the pressure stabilizing telescopic bag 3-2 contracts, and the pressure stabilizing system 3 is in a state shown in fig. 2. At this time, the PLC control system 15 judges that the water inlet pressure is normal, and the audible and visual alarm device 3-5 is closed. Simultaneously, the first electromagnetic valve 2, the second electromagnetic valve 6 and the high-voltage switch 8 are automatically opened to perform normal water production. In addition, bacteria are easy to breed in a raw water barrel arranged at a water inlet of the traditional water purifying equipment, and the purified water dispenser adopts the pressure stabilizing telescopic bag, so that the generation of dead water can be effectively avoided, the potential bacterial pollution is reduced, and the water quality of effluent is improved.
