Embodiment Construction

[0015] The optimal implementation mode of the present invention is a frame-type machine base composed of an "n"-shaped frame and machine base parts, and a side cover is provided on its side facade. The base part with the filter channel is located at the bottom of the frame-type base, and it is also provided with an upward drain channel connected with the filter channel, an inner buckle screw cap with a sealing gasket, and an inclined guide groove plate. The inverted filter element with the water outlet facing downward is flexibly connected with the base part, and its water inlet and outlet pipes are respectively connected in series in the filter channel. The inner buckle screw cap is screwed tightly on the drain channel and is sealed with it by a gasket. The inclined diversion channel plate is located on the upper surface of the machine base part, and its front lower end is provided with a guide flow hole and protrudes out of the frame type machine base. When the machine need...

Abstract

The invention relates to the field of water treatment, in particular to the depth-type filtration and purification of drinking water. The invention discloses a water draining method for a filtering element of a water purifier. A base with a water inlet pipeline and a water outlet pipeline is positioned at the bottom of the machine; the filtering element is inverted on the base; a water inlet and a water outlet of the filtering element are correspondingly communicated with the water inlet pipeline and the water outlet pipeline of the base to form a filtering channel; a draining channel for draining water in the filtering element and a draining device for controlling the on-off of the draining channel are arranged on the base; the draining device conducts the draining channel connected with the filtering channel when the water inlet pipeline of the base is in a closed state; and water in the filtering element is drained by gravity through the draining channel. The invention has the following advantages that the filtering element is clean and sanitary without pollution in the replacement process, and can be replaced by users conveniently, and the product has high grade.

Description

technical field [0001] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0002] At present, water purifiers are relatively popular in China. When drinking water is used, the water purifier is used to deeply filter the impurities in the water and water pipelines, which better protects the health of users. As a consumable of the water purifier, the filter element needs to be replaced after being used for a period of time. However, with the popularization of water purifiers, their defects and deficiencies in application are gradually exposed: most of the middle and low-priced water purifiers use an open liner configuration bare metal model. The machine structure in which the filter housing with built-in liner is hoisted under the machine base, although the filter housing can be reused, correspondingly reduces the cost of replacing the filter element by 10-20% for co...
