Description

Water purification unit with top moves part

Technical Field

The application belongs to the technical field of water purification unit, especially relates to a water purification unit with top moves part.

Background

Nowadays, water resource pollution is more and more serious, and the problem of urban water safety is particularly serious. Aiming at the problem of secondary pollution of tap water and harmful substances in the tap water caused by source water pollution, more and more families apply water purifiers to filter purified water, so that the water purifiers become one of the visible household appliances in daily life. The water purifier gets rid of impurity such as solid particle, bacterium virus, harmful chemical substance in aquatic through the filter core to make water reach certain cleanliness factor, nevertheless along with the extension of live time, impurity in aquatic can block up the filter core, consequently need regularly unpick and wash or change the filter core, in order to ensure that the water purifier normally works.

The filter element fixing mode of the existing water purifier comprises a thread fixing mode, a rotary clamping mode, a hoop type fixing mode and the like, and the purposes of fixing the filter element and preventing the filter element from being separated from a matching structure can be achieved. Wherein, the thread tightening mode is when changing the filter core, and the filter flask lid need be twisted out with the help of supporting spanner more, and it is troublesome to trade the core, and the dismouting is very hard consuming time, and the operating efficiency is lower, leaks easily moreover, has certain requirement to the size of screwing in, and user experience is relatively poor. When the filter element is replaced or installed in a rotary clamping mode, the filter element assembly needs to be lifted up firstly to form a certain angle with the water purifier body, and then the filter element assembly is screwed down or screwed down, so that the filter element replacement operation is very inconvenient, the filter element replacement operation is only suitable for small-size filter elements, and for large-size filter elements, a user cannot lift and rotate the filter element easily; and many users are not clear to need to rotate the filter core by a few degrees when screwing up, lead to the user can not install by oneself, need rely on professional maintainer to go to the door and operate, increase the maintenance cost height. The staple bolt type fixed filter element can only be suitable for a small-size filter element, and the burst pressure received by the large-size filter element is very large, so that the staple bolt can be bounced off or broken at a certain position, the potential safety hazard exists, the using effect of the water purifier is poor, and the user use experience is influenced.

The above description is included in the technical recognition scope of the inventors, and does not necessarily constitute the prior art.
