Description

A clean kettle that can prevent mixing of raw water and clean water

technical field

The invention relates to a water purification jug, in particular to a water purification jug capable of preventing raw water and purified water from mixing.

Background technique

In the water purifier industry, the kettle is very popular with the public because of its portability and beautiful appearance. The clean kettle usually includes a kettle body, a filter cartridge and a kettle liner. When the user pours tap water (commonly referred to as raw water) into the water purification jug, there may be a phenomenon of mixing the raw water and the purified water, and the bacteria, colloids, heavy metals and other substances in the raw water will threaten the health of the user.

In the prior art, a common water purification kettle uses a silicone ring to seal the edge of the filter cartridge and the kettle liner to prevent raw water from mixing with purified water. But there are still following problems:

1. The user is prone to improper assembly of the filter cartridge and the inner tank during use, resulting in misalignment of the silicone ring, resulting in a gap between the filter cartridge and the kettle inner tank, through which raw water flows into the water purification area, polluting the clean water, and failing to achieve Purifying effect.

2. The silicone ring in the water purification pot that has been used for a long time will be aging and deformed, easily damaged, and cannot achieve the effect of sealing water, resulting in secondary pollution of raw water mixed with purified water through infiltration, and the best purification effect cannot be achieved.

Contents of the invention

The object of the present invention is to overcome the deficiencies of the prior art and provide a water purification pot that can prevent the mixing of raw water and purified water. The possibility of secondary pollution makes the purification effect better.

The object of the present invention is achieved through the following technical solutions:

A water purification kettle capable of preventing raw water from mixing with purified water, comprising a kettle body, a kettle inner tank, a filter cartridge disposed in the kettle inner tank, and a filter element disposed in the filter cylinder for purifying raw water; it is characterized in that the kettle The liner includes an upper liner for raw water buffering and a lower liner for assembling with the filter cartridge; the bottom of the lower liner is provided with a pillar extending upward; the top of the filter cartridge is provided with a filter element for raw water to enter The raw water inlet, the bottom of the filter cartridge is provided with a clean water outlet, the upper end of the outer wall of the filter cartridge is provided with a sealing ring that fits the inner wall of the lower liner, and the bottom of the filter cartridge is provided with an upwardly extending A hollow support cylinder, the pillars extend into the support cylinder, and the top surface of the pillar is supported on the top surface of the inner cavity of the support cylinder; after the filter cartridge is assembled with the lower inner tank, the inner wall of the lower inner tank and the outer wall of the filter cartridge The space between them forms a clean water buffer area, which includes the annular area between the inner side wall of the lower liner and the outer side wall of the filter cartridge, and the net area between the bottom upper surface of the lower inner liner and the bottom lower surface of the filter cartridge.
