Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water treatment equipment, in particular to a reverse osmosis direct drinking water device. Background Art
[0002] In direct drinking water treatment equipment, reverse osmosis is generally used to filter bacteria, impurities, heavy metals, etc. in the water. General reverse osmosis water treatment devices treat water through early filtration, centrifugal pumps, and RO reverse osmosis components. However, the filtration effect of general reverse osmosis water treatment devices is not good, and the early impurity filtration is not comprehensive, which increases the replacement frequency of the RO reverse osmosis components and makes it more troublesome to use.
[0003] In order to solve such problems, Chinese patent CN217265257U, a high-efficiency reverse osmosis raw water treatment device points out that by setting the treatment tank, ultraviolet waterproof lamp, through hole and titanium dioxide disc on the carrier, the internal organic matter of the raw water is greatly decomposed and disinfected before the reverse osmosis treatment, thereby improving the rate of subsequent reverse osmosis treatment and improving water quality. The raw water after disinfection is further purified by the guide pipe, polysulfone layer, polyester base layer, feed channel gasket, connector, mounting part, tee pipe, connecting pipe and raw water pipe on the protective shell, thereby obtaining fresh water and concentrated water. At this time, the quality of the fresh water obtained after treatment is significantly improved compared with the traditional device, and the processing time is significantly reduced, thereby greatly improving the water treatment efficiency. The above patent can indeed increase the efficiency of water treatment, but there are certain shortcomings. First, the early impurity filtration is not set (according to the patent drawings Figure 1 Secondly, in actual use, water pressure is generally achieved by a centrifugal pump, and there are certain problems with the size of the pressure. If the pressure is too high, it can be filtered through multiple groups of RO reverse osmosis components, while when the pressure is low, the internal pressure of multiple groups of RO reverse osmosis components is low, and the water cannot be reverse osmosis treated more effectively. Therefore, this patent does not have a pressure matching structure, and therefore cannot adapt to changes in the filtration state of the water pressure.
[0004] Therefore, in order to achieve the matching conditions of water pressure, and to be able to effectively remove and filter impurities in the early stage, and to make cleaning more convenient, and reduce the replacement frequency of RO reverse osmosis components, a reverse osmosis direct drinking water device is hereby proposed.

[0027] In this embodiment, the specific working principle is as follows: when the device is actually used, the water enters the impurity filter box 2 through the water inlet pipe 4 for preliminary impurity filtration, wherein the installation and cleaning of the filter structure are relatively convenient, and then enters the centrifugal pump 3 through the transmission pipe 5, and then enters the RO reverse osmosis water treatment pipe 9 through the connecting pipe 7 for filtration, wherein a water pressure sensor 8 is provided on the connecting pipe 7 to detect the water pressure in the connecting pipe 7, and then matches the solenoid valve 10 according to the size of the water pressure.
