Embodiment 1

[0034] Example 1. The cover and the base are connected as a whole through a standard part or a threaded structure, and the gap between the two is sealed with a seal to form a closed inner cavity, and the seal acting between the base and the waterway switch is separated into a closed large cavity. , small cavity, and connected to the base inlet and outlet pipelines respectively. The fixed plate is limited by the limit device and the base and the cover and can only move axially. The rotating disk and the fixed disk correspondingly contact and cooperate with the rotation of the rotating shaft body to form a sealed and rotating switching interface.

[0035] A group of ring-shaped equally divided switch contacts and ring contacts are arranged around the rotating shaft outside the base, and a transition contact is arranged on the lower end surface of the top knob of the rotating shaft. The transition contact drives the rotating disc to rotate with the rotating shaft body, conducts...

Embodiment 2

[0044] Example 2. On the basis of Embodiment 1, under the premise of not changing the structure and switching connection relationship between the elastic transition contact of the switching position prompting device and the ring contact on the circuit board and the ring-shaped equally divided switching contact 8, the waterway switch Change the switching mode of "Connection with the same disk, closed-loop switching" to Figure 5-6 The switching mode of "different disk connection, closed-loop switching" shown can also detect and prompt each switching position of the waterway switcher.

[0045] The elastic transition contact on the corresponding knob conducts the annular contact 9 on the circuit board and the contact 81 on the annular bisection switching contact 8, and the switching position prompting device prompts that the waterway switcher is in the "filtering" position, and the tap water passes through the machine Seat water inlet pipeline, closed inner cavity, waterway swit...

Embodiment 3

[0048] Example 3. figure 1 and Figure 7 The combination shows the technical solutions of the present invention for open-loop switching, closed-loop pipeline connection, and switching position prompting. During the rotation of the rotating disk 1, the water inlet bend hole 11 and the switching blind hole 13 on the rotating disk 1 respectively correspond to two sets of fixed disk 2 switching nozzles to switch to form an open-loop switching mode: the water inlet bending hole 11 on the rotating disk 1 is in turn When docking with the switching nozzles 21, 23, 24, 25, 26, 27, 28, 29, 22 of the fixed plate respectively, the switching blind hole 13 is correspondingly connected with the switching nozzles 30, 31, 32, 33, 34, 35, 36, 37. Wherein, the fixed plate switching nozzles 21, 23, 24, 25, 26, 27, 28, 29, 22 are the first group of filter switching nozzles respectively connected in the segmented pipelines between the eight series-connected filter galls; The eight switching wate...

Abstract

The invention relates to a water treatment industry, and in particular relates to drinking water filtering. The invention discloses a switching position prompting method for a multi-filtering-liner backwashing switcher of a water purifier. The switching position prompting method comprises 3-8 filtering liners which are connected in series with one another, a base, a water path switcher, annular equal switching contacts, a rotating shaft body with a center rotating arm elastic contact terminal and a switching position prompting device, wherein the upper end of the rotating shaft body extends out of a shaft passing hole of the base; the center rotating arm elastic contact terminal on the rotating shaft body is connected with one end of a corresponding detection switch circuit of the switching position prompting device; all the annular equal switching contacts correspond to all equal switching positions of the water path switcher and have the same switching angle; one contact is connected with the other end of the detection switch circuit; every time when the rotating shaft body drives a rotating disk to rotate to be staggered from one equal switching position, a backwashing channel of the corresponding filtering liner is formed; the center rotating arm elastic contact terminal is in contact with one of the annular equal switching contacts; the switching position prompting device prompts the switching position to the water path switcher.

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] After the filter gall of the water purifier is used for a period of time, the filter material of the filter gall is gradually blocked by impurities and adsorbed on the outer surface of the filter material, resulting in a significant decline in filtration and adsorption effects. Moreover, as the filter gall retains more and more impurities , often make the "pollution" degree of the filter gall impurities exceed the "pollution" degree of the drinking water itself, so that the filter gall becomes a new "pollution" source. Most of the medium and low-priced water purifiers use an open liner to configure a bare metal model. The filter shell with built-in liner is hoisted under the machine base. Although the filter shell can be reused, which reduces the cost of replacing the filter by 10-20%,...
