Water purifier

Technical Field

The utility model belongs to the technical field of the water purifier, a water purifier is related to.

Background

The water purifier is water treatment equipment for deeply filtering and purifying water according to the use requirement of water. Along with the improvement of living standard of people, the requirement on the quality of drinking water is higher and higher, and the use of the purifier is more and more popular.

Conventional water purifiers, for example, chinese patent literature documents disclose water purifiers [ application No.: 200420094564.8, respectively; authorization notice number: CN2741960Y ], comprising a fixed seat, a switching valve and a filter element, wherein the fixed seat is provided with a water inlet and a water outlet connected to a water supply pipeline, the switching valve seat is fixed on the fixed seat and is provided with a water inlet and a water outlet corresponding to the water inlet and the water outlet of the fixed seat, the valve core is movably disposed between the valve seat and the fixed seat and is provided with a water inlet hole and a water outlet hole corresponding to the water inlet and the water outlet of the valve seat, the filter element is detachably fixed on the fixed seat, the water inlet and the water outlet of the filter element are sleeved with the water inlet hole and the water outlet hole of the valve core, the valve core can be rotated by rotating the filter element, so that the water inlet hole of the valve core is communicated or not communicated with the water inlet of the valve seat, the water inlet of the filter element meets the periphery of the filter element, and the water outlet thereof is communicated with the interior of the filter element.

When the filter element needs to be replaced, the rotary lower filter body drives the valve core to rotate, so that the water inlet hole of the valve core is not communicated with the water inlet hole of the valve seat, water of an upstream water supply pipeline cannot be sprayed out, and the purpose of replacing the filter element can be achieved without closing water supply or detaching the water purifier from the pipeline. However, when the filter element of the water purifier with the structure is replaced, the upstream water supply is only cut off, a certain pipeline is arranged at the downstream of the water purifier, the pipeline has water storage, the water storage has the problem of backflow when the filter element is replaced, and water still seeps out to wet the installation environment when the filter element is replaced, so that inconvenience is brought to the replacement of the filter element.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a water purifier to the above-mentioned problem that exists among the prior art, the technical problem of solution can not seep water when how making the water purifier renew cartridge, makes the filter core change convenient.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a water purifier, is including the disk seat that has water inlet and delivery port, be equipped with case and filter core in the disk seat, inhalant canal and exhalant canal have in the case, rotate the case enables the water inlet of disk seat is linked together through inhalant canal, filter core and exhalant canal and disk seat's delivery port, its characterized in that, the epirelief is provided with into water end cap and play water end cap on the case, rotates the case enables into the delivery port that makes play water end cap shutoff disk seat when water end cap shutoff disk seat water inlet.

When the filter element needs to be replaced, the valve core is rotated, so that the water inlet of the water inlet plug blocks the water inlet of the valve seat, the water inlet plug blocks the water path on the upper stream of the water purifier, the water outlet of the water outlet plug blocks the water path on the lower stream of the water purifier, the water paths on the upper stream and the lower stream are blocked when the filter element is replaced by the water purifier, the problem of water seepage cannot exist, the installation environment cannot be wetted, and the filter element is convenient to replace.
