Description

Filter capable of automatically exhausting

Technical Field

The present invention relates to a filter, and more particularly, to a filter capable of automatically exhausting air.

Background

At present, non-woven fabrics class filter receives the restriction of structure, if not exhaust the use, remains the air in the cartridge filter, and water can not be full of the cartridge filter, leads to can only partly filter the filter core through rivers, and the unable whole utilization of filter core influences filtration efficiency, therefore non-woven fabrics class filter will discharge the air in the cartridge filter in water pump operation earlier stage. The existing exhaust structure of the filter is characterized in that an exhaust hole is formed in the top of a filter cartridge, an exhaust nut is installed in the exhaust hole, the exhaust nut is loosened in the early stage of operation of a water pump, and the exhaust nut is screwed after water in the exhaust hole comes out after exhaust is finished, so that exhaust operation of the filter is finished. The exhaust mode needs manual exhaust operation, which brings inconvenience to the use of the filter.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes current filter needs artifical manual operation of exhausting, and the use of giving the filter has brought inconvenient not enough, provides a but self-bleeding's filter, and it can self-bleeding at the in-process that uses, makes the use of filter more convenient.

In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides a but self-bleeding's filter, includes the cartridge filter, and the cartridge filter upper end sets up the exhaust hole, and the core vent of installation liftable in the exhaust hole is equipped with the floater on the core vent, and the core vent upper end is equipped with the venthole, is equipped with the air vent with the venthole intercommunication on the core vent outer wall, and the floater top is arranged in to the air vent, and the cartridge filter is arranged in to the floater.

When the filter works, water flow enters the filter cartridge, air in the filter cartridge is discharged outwards from the vent hole in the exhaust plug through the air outlet hole, when the filter cartridge is full of water, the floating ball floats upwards to push the exhaust plug to move upwards, so that the vent hole moves upwards in the exhaust hole, and the vent hole is blocked and sealed to finish automatic exhaust operation. The filter capable of automatically exhausting can automatically exhaust in the using process, so that the filter is more convenient to use.

Preferably, the outer wall of the vent plug is provided with a convex ring, and the convex ring is arranged between the floating ball and the vent hole. After the floating ball floats to the top, the convex ring is abutted to the edge of the end part of the exhaust hole, so that good positioning and sealing effects are achieved.

Preferably, the exhaust plug is sleeved with a sealing ring, and the sealing ring is supported on the upper end face of the convex ring. The sealing ring increases the sealing performance.

Preferably, an extension sleeve is arranged at a position corresponding to the vent hole in the filter cartridge, and the vent plug is in adaptive connection with the extension sleeve. The arrangement of the extension sleeve ensures that the vent hole can be blocked and sealed after the vent plug moves upwards.

Preferably, the upper end of the vent plug is provided with a limiting cap, and the limiting cap can be supported at the upper end of the filter cylinder. The limiting cap has good positioning effect on the exhaust plug.

Preferably, the filter cartridge comprises a cylinder body and an upper cover, the upper cover is tightly installed at the upper end of the cylinder body, and the vent hole is formed in the upper cover. The cartridge filter is formed by connecting the cylinder body and the upper cover together, and is convenient to assemble.

Preferably, the lower surface of the upper cover is provided with an inner ring and an outer ring, a filter element is arranged in the filter cartridge, the upper end of the filter element is arranged between the inner ring and the outer ring, and the floating ball is arranged in the filter element and close to the upper part. The arrangement of the inner ring and the outer ring on the upper cover is convenient for the installation of the filter element.

Compared with the prior art, the beneficial effects of the utility model are that: the filter can automatically exhaust in the using process, so that the filter is more convenient to use.
