Description
Technical Field
The invention relates to the water treatment industry, in particular to the aspects of deep filtration and purification of drinking water.
Background
As the consumptive material of purifier, filter courage after using a period, need change the filter courage. However, with popularization of water purifiers, defects and shortcomings of the water purifiers in application are gradually exposed: the water purifier with middle and low price mostly adopts an open type liner configuration bare metal mode. The shell with the built-in liner is hung below the machine structure of the machine base, although the shell can be reused, the cost of replacing the liner by a consumer is correspondingly reduced by 10-20%, the water purifier is required to be taken out and put on the air when the liner is replaced, and then a special liner wrench is sleeved on the shell from bottom to top and is forcibly rotated to loosen the threaded connection of the shell and the machine base, so that the shell is detached. After the new liner is replaced, the shell with the liner is tightly screwed below the machine base, and the whole operation process is very labor-intensive. Because the water purifier with water is heavy, and the built-in filter liners in the open filter cartridge are all poured out together with the water after the filter cartridge is detached, the water pollution treatment is very troublesome. For the horizontal water purifier, the use is very convenient: can be placed on the table top of a kitchen cabinet or in the cabinet; the machine is only required to be directly placed at the using position, and the punching hanging machine is not required. Because the filter liner is positioned above the machine base, the filter liner is convenient to replace, and the time and the labor are saved relatively. However, the biggest problem of adopting the seat type water purifier structure is that the machine operation surface is small, the display component and the operation control device can only be arranged on the side elevation of the machine, the top surface is used for replacing the filter liner, and the water passing control component can be placed in no place. Since the water purifier has limited length, width and height dimensions, which are generally less than 500 mm×200 mm×450 mm, the placement of the display control device on the machine side elevation will affect the number of filter liners placed. When the closed filter liner is used, water in the filter liner can flow out from the water gap of the filter liner to pollute the surrounding environment when the filter liner is replaced because the water gap of the filter liner faces downwards. The water in the filter element at the front and the back of the replaced filter element flows out from the water inlet and outlet pipelines of the corresponding machine seat of the detached filter element. The above-mentioned drawbacks and disadvantages make it difficult to obtain a water purifier that is more widely popularized.

Basic mode one (boss is arranged along radial direction) of a spin-card connection structure mode between the spin-card device and the self-supporting filter liner is as follows: the spin-card device of the upper module in the two spin-card connecting parts corresponding to the spin-card connecting circle is vertically provided with a group of overhanging wall structures along the axial direction at the inner side position corresponding to the spin-card connecting circle, and corresponding transverse bosses are arranged along the outer side walls of the group of overhanging wall structures to form a group of corner-shaped overhanging wall structures (along the radial outward direction) and is defined as a columnar spin-card structure; the two parts of the overhanging wall structure and the boss are positioned on the three circumferential layer structures (the inner layer wall structure, the outer layer wall structure and the middle layer wall structure are in axial fit, so that the boss structures with the grooves (inserting space is reserved) are arranged on the two groups of the boss structures in the transverse directions, so that the bosses in the transverse directions of the two oppositely arranged two rotating clamp connection structures are staggered with each other, and the boss structures are axially mutually inserted at the opposite grooves (the releasing position) and then are rotationally matched to the locking position to form axial connection (the locking position).
When the spin-on device is at the outer side of the corresponding spin-on connection circle, a group of overhanging wall structures are axially arranged, corresponding transverse bosses are arranged along the inner side wall of the group of overhanging wall structures to form a group of corner-shaped overhanging wall structures (along the radial inward direction), the corner-shaped overhanging wall structures are defined as ring-column spin-on structures, the corresponding self-supporting filter liners are axially arranged at the inner side of the corresponding spin-on connection circle, a group of overhanging wall structures are axially arranged, corresponding transverse bosses are arranged along the outer side wall of the group of overhanging wall structures to form a group of corner-shaped overhanging wall structures (along the radial outward direction), and the splicing relationship between the two corner-shaped overhanging wall structures is the same as that of the columnar spin-on structure, namely, the transverse bosses of the two groups of corner-shaped overhanging wall structures are arranged into boss structures with notch grooves (a splicing space is reserved, not shown), so that the transverse bosses of the upper and lower opposite spin-on connection structures are staggered with each other, and are axially inserted with each other at the notch of the other, and then are rotationally matched to the locking position to form an axial connection (locking position) after the two-on the inner side of the filter liner is axially inserted into the lock groove to form the lock position.

The corner type overhanging wall structures of the two rotary clamping connecting parts are arranged up and down oppositely and staggered, and are axially inserted into each other at the notch (disengaging position) of the other side and then are rotationally matched to the locking position to form axial connection (locking position). The mode is characterized in that: the overhanging wall structure and the boss of the two parts are positioned on a circumferential layer structure in the spin-card matching state. The spin-card mating mode is defined as a "gear spin-card mating mode".

The stop block is arranged on a rotating channel at the rear end of the corner-type overhanging wall structure of the self-supporting filter liner, corresponds to the front end of the rotating clamp connecting structure at the lower part of the rotating clamp device, or is arranged on a rotating channel track at the rear end of the rotating clamp connecting structure at the lower part of the rotating clamp device, and corresponds to the front end of the corner-type overhanging wall structure of the self-supporting filter liner.
