Description
技术领域technical field
本发明属于净水设备领域，尤其涉及一种多滤芯并联式陶瓷净水器。The invention belongs to the field of water purifying equipment, in particular to a multi-filter parallel ceramic water purifier.
背景技术Background technique
目前，在对陶瓷滤芯净水器滤芯进行清洗时，是将净水器卸开，用清水冲去陶瓷滤芯上由刮片或刷子清理下来的污垢，使其恢复通透性。当自来水压力较小或者水质较差时，需要经常卸开净水器清洗陶瓷滤芯。这样操作麻烦且容易对滤芯造成损耗，发明专利CN204798967U 对上述缺陷进行改进：利用微型齿轮减速电机作动力源，其输出轴与免拆洗陶瓷滤芯净水器洗刷组件磁力传动式机构的外磁环端部或机械传动式机构的传动轴连接；在净水器外壳圆筒的排污口上，接有电磁阀；微型齿轮减速电机和排污电磁阀由时间程序控制器控制。但是依旧存在以下问题，1.需要电机作为动力源；2. 对于清除清扫下来的污垢还需要通过增设排污阀来实现；3.由电机驱动的洗刷组件会持续对陶瓷滤芯进行洗刷，容易对陶瓷滤芯造成损耗，减短陶瓷滤芯的寿命。At present, when the filter element of the ceramic filter element water purifier is cleaned, the water purifier is disassembled, and the dirt cleaned by scrapers or brushes on the ceramic filter element is washed away with clear water to restore the permeability. When the tap water pressure is low or the water quality is poor, it is necessary to remove the water purifier frequently to clean the ceramic filter element. This operation is cumbersome and easy to cause loss to the filter element. The invention patent CN204798967U improves the above defects: use a micro-gear reduction motor as the power source, and its output shaft is connected to the outer magnetic ring end of the magnetic drive mechanism of the non-removable ceramic filter element water purifier. The transmission shaft of the head or the mechanical transmission mechanism is connected; a solenoid valve is connected to the sewage outlet of the shell cylinder of the water purifier; the micro-gear reduction motor and the sewage solenoid valve are controlled by a time program controller. However, there are still the following problems: 1. A motor is needed as a power source; 2. To remove the dirt that has been cleaned, it needs to be realized by adding a sewage valve; 3. The scrubbing component driven by the motor will continue to scrub the ceramic filter element, which is easy to clean the ceramic filter element. The filter element causes loss and shortens the life of the ceramic filter element.
