Problems solved by technology

However, when the water purifier is manufactured according to the disclosed technical scheme of the above-mentioned patent application, one of the axial inlet and outlet ports of the waterway switch is arranged on the circumferential surface of the closed cavity, while the other water ports are all arranged at the end of the closed cavity. If the cover is closed, the assembly of the waterway switcher is more troublesome. It is necessary to consider the sealing of the end cover connection and the seal of the nozzle on the circumferential surface, resulting in time-consuming assembly of the waterway switcher and the need to increase the sealing device and increase the cost.
In addition, the waterway switcher in the above-mentioned technical solution is not equipped with a switching valve device. When the waterway needs to be closed, the valve of the external pipeline of the water purifier is often closed, which is very inconvenient.
The above defects and deficiencies have seriously affected the upgrading and popularization of water purifier products

Embodiment 1

[0054] Example 1. In order to clearly and completely explain the technical scheme of the water circuit switcher with axial water inlet and outlet ports and the water purifier, the water circuit switcher with axial water inlet and outlet ports and the water purifier using the water circuit switcher Related features are grouped together for elaboration.

[0055] Embodiment 1 is the optimal embodiment of the present invention, appended figure 1 Among them, the Jiushuikou waterway switcher adopts the combination mode of eight filter elements, closed-loop switching structure and forward filtering channel.

[0056] The waterway switcher is located in the closed cavity and is axially limited and integrated with the machine base. Under the pressure of the two end faces of the closed cavity, the fixed plate 2 is fixed with the closed cavity and cannot move radially. It cannot move axially, let alone rotate. Only the rotating disk 1 can rotate around the common axis of the two disks ...

Embodiment 2

[0074] Example 2. attached image 3 Among them, on the basis of Embodiment 1, a second intermediate water outlet is set in each controlled water outlet of the fixed plate, and the tail part of the filter channel of the serially connected filter element is connected correspondingly. The second middle water outlet 27 connected to the middle water outlet 28 and the closed position are respectively located adjacent to the inner and outer sides of the middle water outlet 28 .

[0075] The transition blind hole 13 of the rotating disk is a special-shaped blind hole corresponding to two adjacent nozzles of the fixed disk, and is adjacent to the water outlet 11; the special-shaped blind hole is composed of two transition blind holes 13, 13a. On the same circle, the fixed plate water inlet 21 and the second middle water outlet 27 located on both sides of the closed position respectively connect with the rotating plate water outlet 11 and the transition blind hole 13a to form a filter ...

Embodiment 3

[0078] Example 3. The waterway switcher is a combined mode of open-loop switching structure and forward filtering channel, and the number of controlled water outlets on the same circle where the fixed plate is equally divided into switching positions is set according to the basic mode of "the number of filter elements multiplied by two plus one".

[0079] attached Figure 5 Among them, a group of 9 controlled water ports located between the water inlet 21 of the fixed plate and the middle water outlet 30 correspond to both sides of each filter element in the 8 serially connected filter elements, and the other group is used for recoil. The water outlets are respectively connected to the water inlets of the corresponding filter elements in turn; the fixed disk water inlet 21 and the middle water outlet 30 are connected with the rotating disk water outlet 11 and the transition blind hole 13 respectively. The fixed disc closed position is located between the water inlet 21 and th...

Abstract

The invention is associated with the water treatment industry and specifically relates to purification of drinking water. The invention discloses a waterway switcher with axial water inlet and outlet interfaces and a water purifier. The waterway switcher also comprises a central interface and an eccentric interface which cooperate with an end cap. The number of controlled water nozzles which are arranged on the same circle of a fixed disc and are controlled by a rotary disc is one less than the number of equal switching positions. The waterway switcher comprises a water inlet and a middle water outlet which are correspondingly connected in series with head and tail of filter elements and corresponding filter element pipeline interfaces which are respectively sealingly in butt joint to cooperate with the end cap. The eccentric interface is communicated with an inner cavity and a rotary disc water-passing port through a water-passing channel. The central interface is communicated with a central blind hole and a transition blind hole of the rotary disc through the fixed disc. The equal switching position which isn't provided with a controlled water nozzle is an off-position. The rotary disc rotates to stagger one equal switching position to correspondingly form a back-flushing channel of a single filter element. When the rotary disc water-passing port or the transition blind hole is positioned at the off-position, the waterway switcher is in an off state.

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 using water, the water purifier is used to filter the water and the impurities caused by the water pipeline in depth, which better protects the health of users. Chinese patent applications 200910226508.2, 200910224481.3, 200910246024.4, 200910224652.2, and 200910215159.4 all disclose related technical solutions that all filter elements of the water purifier are backwashed to significantly improve the performance of the water purifier. However, when manufacturing the water purifier according to the disclosed technical scheme of the above-mentioned patent application, one of the axial inlet and outlet ports of the waterway switch is arranged on the circumferential surface of the closed cavity, while the other water ports a...
