Description

Water purifier with U-shaped double-bin stacking structure and self-closing bin manufacturing method thereof

Technical Field

The invention relates to the water treatment industry, in particular to the aspects of deep filtration and purification of drinking water.

Background

At present, the water purifier is adopted to carry out deep filtration on impurities and the like caused in water and a water conveying pipeline, so that the health of a user is well protected. As the filter liner of the water purifier is required to be replaced regularly in the using process after the water purifier is purchased and installed by a user. A series of matters and expenses generated around the replacement of the filter liner are always accompanied with the use process of the water purifier, so that the sales of the water purifier products are different from the sales of other household electrical appliances, the sales of the water purifier products are called as semi-finished products, and a seller needs to have strong maintenance service capability for supporting. Along with the popularization improvement of the water purifier and the gradual popularization of the fast-assembling filter liner, a user can replace the filter liner by himself, so that the use cost of the water purifier is reduced. However, the water purifier has the characteristics of long-term continuous operation, great influence of environmental factors on the filtering effect and the service life of the filter liner, and the maintenance content of the water purifier mainly comprises the replacement of damaged parts. Although the machine maintenance principle is relatively simple and not numerous, the maintenance process is quite complex. Moreover, because the water purifier is influenced by the use environment, the size of the water purifier is smaller, and the main position space is used for placing the filter liners, the related pipelines are staggered, and the fixed positions of all control parts connected in the filter channel are more concealed and are not easy to disassemble; it is difficult for non-professionally trained personnel to disassemble. For example, most of box-type water purifiers are designed by adopting a three-layer structure consisting of an operation panel, a pipeline and a filter liner, a simple part is often replaced, and most of structures of the water purifiers need to be disassembled, so that the maintenance and replacement of the part only can require professional maintenance service personnel to perform door-to-door service, the workload of the maintenance service personnel is increased, the related expense is increased, and related matters surrounding the door-to-door service are very troublesome. Especially, the remote users who purchase the telephone through the network telephone are difficult to obtain timely and good service. Because the popularity of the current water purifier is less than 3 percent, and parts of manufacturers of the water purifier are not universal, a remote user can only search for repair under the guidance of the manufacturers or distribution units, or stop using a machine to wait for the regular maintenance and itineration service of the manufacturers for home maintenance; or simply remove the machine for return to the manufacturer for repair. This is also the main reason why water purifiers cannot be sold out of professional maintenance networks. The existing defects and shortcomings seriously influence the popularization of the water purifier product.
