技术领域Technical field
本发明涉及一种净水机，特别涉及一种具有RO反渗透过滤芯的净水机。The invention relates to a water purifier, in particular to a water purifier with an RO reverse osmosis filter core.
背景技术Background technique
近年来，随着环境问题越来越突出，人们对于健康饮食的意识也逐步增强，如食品卫生，空气质量和水质安全越来越关注，净水行业迎来蓬勃发展的时期。目前市场上很多净水机(饮水机)大多是厨下式的和立柜式的，厨下式制水速度很慢，难以实现随制随用，影响用户日常生活使用。In recent years, as environmental problems have become more prominent, people's awareness of healthy eating has gradually increased. For example, food hygiene, air quality and water quality safety have become more and more concerned, and the water purification industry has ushered in a period of vigorous development. At present, many water purifiers (water dispensers) on the market are mostly kitchen-type and vertical cabinet-type, and the kitchen-type water production speed is very slow, which is difficult to achieve with the system and affects the daily life of users.
立柜式净水机多是由传统饮水机改变而来，因体积偏大，多放在客厅。受水源和管路限制，受水源和管路限制，不便于采用RO滤芯过滤，因为RO膜过滤会产生一定量的浓水，需要排放掉，因此，很多立柜式净水机只采用微滤、活性炭等简单过滤，达不到真正的净化水。个别净水机采用RO膜过滤的，多增加了一个浓水收集桶，需要定期排放、清空，给用户带来不便。很多单机功能比较单一，操作使用不方便，而且冲洗RO滤芯后的浓水，直接排放掉或者倒掉，对水资源造成了严重的浪费。Most of the cabinet-type water purifiers are changed by traditional water dispensers, and they are mostly placed in the living room due to their large size. Limited by water source and pipeline, limited by water source and pipeline, it is not convenient to use RO filter to filter, because RO membrane filtration will produce a certain amount of concentrated water, which needs to be discharged. Therefore, many vertical cabinet water purifiers only use microfiltration. Simple filtration such as activated carbon does not achieve true purified water. Individual water purifiers are filtered by RO membranes, and a concentrated water collection tank is added, which needs to be periodically discharged and emptied, which brings inconvenience to users. Many single-machine functions are relatively simple, and the operation is inconvenient, and the concentrated water after flushing the RO filter is directly discharged or dumped, causing serious waste of water resources.
因此，鉴于以上问题，有必要提出一种净水机，以提高使用性能。Therefore, in view of the above problems, it is necessary to propose a water purifier to improve the performance.
