Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a swimming pool filter with a diversion structure. Background Art

[0002] With the improvement of people's living standards, swimming pools, as a kind of leisure and entertainment facility, are becoming more and more popular in daily life. The existing swimming pool filters usually adopt a fixed filtering method, and the water flow directly enters the filter through the water inlet pipe. There are some deficiencies in the actual use of this design. For example, when the water flow enters the filter element, it often concentrates on a certain area of the filter element, resulting in the rapid accumulation of impurities in this area. This uneven distribution of impurities will not only accelerate the wear of the filter element, shorten the service life of the filter element, but also affect the filtering effect of the entire filtering system, and cannot effectively guarantee the cleanliness of the overall water quality.

[0003] In addition, due to the uneven distribution of impurities, some areas of the filter element may reach the saturation state prematurely, while other areas are not fully utilized, which further reduces the filtering efficiency. Then, in order to maintain the water quality, users have to replace the filter element frequently or increase the cleaning frequency, increasing the maintenance cost; for this reason, a swimming pool filter with a diversion structure is proposed. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a solution that can effectively solve the problems in the background art.

[0012] Preferably, the limiting structure includes a support ring provided on the housing, several limiting blocks provided on the support ring, and several limiting ports provided at the bottom of the outer ring and adapted to the limiting blocks.

[0013] The utility model has the following beneficial effects:

[0014] Through the setting of the diversion plate, when water flows in from the water inlet and reaches the diversion plate, when passing through the diversion plate, the water flow is evenly divided under the action of each spiral water diversion channel and rotates to form a rotational flow, and finally evenly enters from the outside of the filter element, avoiding the water flow concentrating on one place to enter the filter element, thereby improving the service life and filtration efficiency of the filter element;

[0015] Through the setting of the slot, when the cover plate is tightened, the cover plate is completely docked with the housing, and the top of the limiting cylinder abuts in the slot, so as to complete the fixation of the diversion plate, avoiding the shaking of the diversion plate caused by the water flow affecting the normal work; by setting the gap between the limiting cylinder and the slot, the cover plate and the housing will not be interfered by the limiting cylinder during the rotary installation process, resulting in the cover plate driving the limiting cylinder to rotate when rotating, causing the threaded connection between the limiting cylinder and the central column to become disconnected or tightened and then driving the diversion plate to rotate, while the diversion plate is limited by the limiting blocks and the limiting ports, so as not to affect the connection between the cover plate and the housing;

[0016] By setting the central column as a cone, it plays a role in guiding the water falling on the central column and avoiding remaining on the central column. At the same time, in combination with the setting of several diversion vanes, a spiral water diversion channel expanding outward is formed, which can guide the water flow outward to form an outward expanding spiral, enabling the water flow to more easily enter from the side, that is, the water inlet surface of the filter element, and improving the filtration efficiency;

[0017] Through the setting of the threaded docking groove, it is convenient for the connection between the limiting cylinder and the central column, and the disassembly and assembly are convenient;

[0018] By providing the limiting blocks on the support ring to be adapted to the limiting ports provided on the outer ring of the diversion plate, the support ring plays a role in supporting and limiting the diversion plate, and the cooperation of the limiting blocks and the limiting ports plays a role in limiting the circumferential position of the diversion plate, reducing the shaking and rotation of the diversion plate caused by the water flow during work and increasing the stability of the diversion plate during work.
