Filter element and water purification equipment

Abstract

The invention relates to the field of water purifying and drinking equipment, and provides a filter element and water purifying equipment, the filter element comprises a shell, a filter element body, a central pipe and an air compression unit, the central pipe is arranged in a second flow channel, the first end of the central pipe is communicated with a water outlet channel, and the second end of the central pipe is communicated with the second flow channel and extends in the direction away from the water outlet channel; and the air compression unit is arranged in the second mounting cavity. The central pipe is arranged in the second flow channel of the filter element body and used for balancing the pressure difference between the water inlet path and the water outlet path, so that the flow speeds of all positions of the filter element body are the same, and the utilization rate of a filter material is increased; under the condition of the same volume and the same use amount of the filter material, the utilization rate of the filter material is effectively improved, so that the filtering performance of the filter element body is improved, the service life of the filter element body is prolonged, and the use cost of the filter element is reduced; and under the requirement of the same performance, the design consumption of a filter material can be reduced, the volume of the filter element is reduced by about 30% or above, and the product competitiveness is improved.

Description

technical field [0001] The invention relates to the field of water purification and drinking water equipment, in particular to a filter element and water purification equipment. Background technique [0002] With the improvement of people's living standards and awareness of drinking water safety and health, the use of water purifiers in ordinary households is becoming more and more popular. The filter element is the core component of the water purifier, and the performance of the filter element determines the performance of the water purifier. [0003] For the filter element of the related art, the closer the water inlet and outlet of the filter element are, the greater the pressure difference between the water inlet and outlet. Since the pressure difference between the inlet and outlet water is directly proportional to the flow velocity of the purified water, the closer to the inlet and outlet of the filter element, the greater the flow velocity of the water, and the farthe...

AI Technical Summary

Problems solved by technology

Since the pressure difference between the inlet and outlet water is directly proportional to the flow velocity of the purified water, the closer to the inlet and outlet of the filter element, the greater the flow velocity of the water, and the farther away from the inlet and outlet of the filter element, the smaller the flow velocity of the water, and even a "dead water area". This part of the filter material is actually not used and occupies a certain space, so that the filtering performance of the filter element is not fully utilized, and the service life of the filter element cannot be effectively utilized.
