Description

Technical Field

[0001] This utility model relates to the field of pre-filter technology, and in particular to an anti-clogging pre-filter. Background Technology

[0002] A pre-filter, as the name suggests, is a filtration device installed at the beginning of the water supply line. It is typically installed after the water meter and before all water-using appliances, serving as a preliminary filtration barrier for the entire house's water supply.

[0003] Many existing pre-filters do not have the function of automatically cleaning the filter screen. They rely on manual disassembly and cleaning or regular replacement of the filter screen to maintain the filtration effect. This not only increases the maintenance burden on users, but also easily leads to filter screen clogging if maintenance is not timely or inadequate, affecting water quality and the normal operation of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging pre-filter. This device prevents the pre-filter from becoming clogged, thus solving the problem of easy clogging in existing pre-filters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pre-filter designed to prevent clogging includes a bottom cover with multiple connecting rods arranged in a circular array inside the bottom cover, the ends of which are fixedly connected to a connecting seat; a housing located above the bottom cover, containing a cylindrical column with slots extending through both sides of the column, a filter screen inside the sidewall of the column, a rotating rod inside the column, multiple rod bodies fixedly connected to both sides of the rotating rod, a vertical plate fixedly connected to the ends of the rod bodies on each side, a brush fixedly connected to the sidewall of the vertical plate, the brush fitting against the sidewall of the filter screen, and a blade fixedly connected through the lower end of the rotating rod.

[0007] Preferably, an inlet pipe and an outlet pipe are fixedly connected through both sides of the bottom cover, and the end of the inlet pipe is connected to the connecting seat.

[0008] Preferably, the upper end of the connecting seat is provided with a groove, and the lower end of the cylindrical column is slidably connected to the groove.

[0009] Preferably, an upper seat is fixedly connected to the top of the housing, and a groove is provided inside the upper seat. The upper end of the cylindrical column is rotatably connected to the inside of the groove via a thread.

[0010] Preferably, the cylinder has a cavity inside, the cavity is connected to the slot, and the cavity is slidably connected to the filter screen.

[0011] Preferably, two crossbars are fixedly connected to the inner walls on both sides of the cylindrical column, and a ring seat is fixedly connected between the ends of the two symmetrical crossbars, and the rotating rod rotates through the ring seat.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. Water is delivered to the connecting seat through the inlet pipe, and simultaneously flows upward into the cylinder. The water flows through the slot and contacts the filter screen, which filters and purifies the water. During the water flow, the blades are pushed, causing the rotating rod to rotate. At the same time, the rotating rod drives the vertical plate to rotate, causing the brush to clean the impurities accumulated on the filter screen. The purified water flows into the bottom cover and is then discharged through the outlet pipe. The automatic cleaning function can effectively prevent the filter screen from clogging, maintain its continuous and efficient filtration capacity, and extend the service life of the filter screen.

[0014] 2. When the filter screen needs to be replaced, remove the housing from the top of the bottom cover, then unscrew the cylinder from the internal thread of the upper seat. After the cylinder is unscrewed, pull out the filter screen from the opening at the top of the cavity for replacement. This eliminates the need for complicated tools or professional skills, allowing operators to easily replace the filter screen, reducing the difficulty of maintenance work and enabling non-professionals to perform basic maintenance.
