Description

Technical Field

[0001] The utility model belongs to the technical field of pet drinking fountains, and in particular relates to a high-efficiency filtering structure and a pet drinking fountain. Background Art

[0002] With the improvement of people's living standards, pets have become important members of many families. For the health of pets, it is essential to provide clean and fresh water. However, traditional water bowls are prone to breeding bacteria, and the water needs to be replaced frequently, which brings great inconvenience to pet owners. Therefore, pet drinking fountains came into being. They are equipped with a filtering structure inside, which can filter impurities and particulate foreign matter in pet drinking water, thereby providing pets with continuous purified water and ensuring the cleanliness and hygiene of the water. However, the water circulation filtration mode of existing pet drinking fountains is generally that the filtering structure is set at the bottom of the water bowl drain for direct filtration, which can easily cause particulate foreign matter to quickly accumulate in the filtering structure, further clogging the filter holes of the filtering structure, affecting the normal filtering effect of the filtering structure, and also requiring users to frequently perform tedious operations to replace the filtering structure, and the product user experience is not ideal. Utility Model Content

[0003] The utility model aims to overcome the problem that the filter structure of the existing pet water dispenser lacks the function of pre-precipitation of particulate impurities, resulting in the need for frequent replacement of the filter structure, and to provide a high-efficiency filter structure with the function of pre-precipitation of particulate impurities and a pet water dispenser.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A high-efficiency filtering structure comprises an overflow basin and a filtering module, wherein the overflow basin is provided with an overflow trough with an opening at the top and a sedimentation structure and a filtering trough arranged along at least one side direction from the overflow trough, the filtering module is installed in the filtering trough, the sedimentation structure comprises at least two overflow ridges arranged at intervals, a plurality of overflow ridges are arranged along the outer direction from the overflow trough and the height of each overflow ridge gradually increases along the outer direction, a sedimentation trough is formed between two adjacent overflow ridges, and an overflow port is formed at the upper end of each overflow ridge.

[0006] Compared with the prior art, the high-efficiency filtering structure of the utility model is achieved by arranging an overflow trough in the overflow basin and arranging a sedimentation structure and a filter trough along the outer side of the overflow trough, and the sedimentation structure includes a plurality of overflow ridges with increasing heights, and a sedimentation trough is formed between adjacent overflow ridges, so that after the liquid water to be filtered enters the overflow trough, it flows to the sedimentation trough and the filter module in turn in an overflow manner, effectively precipitating particulate impurities in the sedimentation trough, avoiding the accumulation of particulate impurities in the filter module and causing the filter module to be blocked, affecting the normal filtering effect, effectively extending the service life of the filter module, and reducing the operation of frequent replacement of the filter module.

[0007] Furthermore, the overflow protrusion and the filter groove are arranged in a ring shape with the overflow groove as the center; the overflow basin is disc-shaped, the overflow protrusion is correspondingly ring-shaped, and the overflow groove is correspondingly ring-shaped; through such an arrangement, the high-efficiency filtering structure has a larger range of particle impurity precipitation area and filtration area, and the water purification effect is better.

[0008] Furthermore, the overflow basin is rectangular.

[0009] Furthermore, the overflow trough is located on one side of the overflow basin, and the sedimentation structure and the filter trough are arranged along the other side of the overflow basin; or, the overflow trough is located in the middle of the overflow basin, and the sedimentation structure and the filter trough are respectively provided on both sides of the overflow trough; through such an arrangement, the high-efficiency filtration structure can be suitable for pet drinking fountains in which the drainage level of the drinking basin is lower than the overflow level height of the filter net, and the product shape is not restricted by the shape, so that triangular, rectangular, polygonal and circular shapes can be used.

[0010] Furthermore, an overflow baffle is formed on the outer periphery of the overflow groove, and a sedimentation groove is formed between the overflow baffle and the adjacent overflow convex edge, and the height of the overflow baffle is lower than the height of the adjacent overflow convex edge; through such an arrangement, the filtering effect of the sedimentation structure on particulate impurities is effectively improved.

[0011] Furthermore, three or more overflow ridges are arranged at intervals, so that at least three sedimentation troughs with different elevations are formed between the multiple overflow ridges and the overflow baffle, which can respectively precipitate and filter large particles, medium particles and small particles.

[0012] Furthermore, the height difference between adjacent overflow ridges is between 1 and 10 mm.

[0013] Furthermore, the overflow basin is integrally formed by injection molding; this arrangement simplifies the production process of the high-efficiency filtering structure and improves production efficiency.

[0014] Furthermore, the overflow ridges are arranged in plurality and are connected to each other via reinforcing ribs. This arrangement effectively improves the structural strength of each overflow ridge and improves product reliability.

[0015] Furthermore, a filter baffle is provided on the outer side of the overflow basin, and the filter groove is formed between the filter baffle and the outermost overflow convex edge, and a filter hole is provided at the bottom of the filter groove; through such an arrangement, the liquid water overflowing outward by the purification filter module is filtered and discharged from the filter hole, thereby ensuring the filtering effect.

[0016] Furthermore, it also includes a filter net, which is adapted to the shape of the filter tank and is used to cover the filter tank. Through such an arrangement, by setting the filter net to cover the opening of the filter tank, the filter module can be effectively fixed.

The water tank is provided with a water storage cavity with an upper opening. The water pump and the high-efficiency filtering structure are arranged in the water storage cavity. The water bowl covers the opening of the water storage cavity. A drain outlet is provided at the bottom of the water bowl. The overflow basin is arranged at the bottom of the water bowl and the overflow trough is located below the drain outlet. The water pump is used to transport liquid water in the water storage cavity to the water outlet assembly, which is discharged into the water bowl by the water outlet assembly.
