Problems solved by technology

In the prior art, the food filter element and the end cap are connected by glue, and the food residue juice is usually weakly acidic or weakly alkaline. If the glue is soaked in such an environment for a long time, it is prone to aging and decomposition, and the decomposed small molecular organic matter is harmful to food. make an impact

Embodiment 1

[0025] Such as Figure 1~3 As shown, the present invention is a filter cartridge for ensuring food safety, comprising a continuous pleated cylindrical filter element 3 arranged between the upper end cover 1 and the lower end cover 2, the inner periphery of the filter element 3 is provided with an inner skeleton 4, and at the upper end The cover 1 and the lower end cover 2 are provided with a groove on the side facing the filter element 3, and glue is arranged in the groove, and the glue is conductive silver glue 5, so that the sides of the filter element 3 are connected to the upper end cover 1 and the lower end respectively. In the groove of the cover 2, a layer of sealing coating 6 is attached above the conductive silver glue 5.

[0026] The upper end cover 1 and the lower end cover 2 are insulating materials, and one end of the first conductive pin 8 is embedded in the conductive silver glue 5 in the groove of the lower end cover 2, and the other end is led out of the lower...

Embodiment 2

[0029] Such as Figure 4 As shown, on the basis of Embodiment 1, a layer of aluminum film 11 is attached to the middle of the inner wall of the inner frame 4, and the aluminum film 11 is connected to the third conductive pin 12, and the third conductive pin 12 is connected to the negative pole of the high-voltage electrostatic generator 13 , the anode of the high voltage electrostatic generator 13 is connected to the first conductive pin 8 .

[0030] When the sealing structure is damaged or cracked, the conductive adhesive will be exposed to the damaged or cracked part and directly contact with the food. Since the solid powder is a non-conductive material, under the high voltage generated by the high-voltage electrostatic generator, due to corona discharge, in its A dense charge is generated nearby, and the powder forms charged particles, which are attracted to the conductive glue opposite to its polarity under the action of electrostatic force, so the powder and the first con...

Abstract

The invention discloses a filter cartridge for ensuring food safety, which comprises a continuous pleated cylindrical filter core arranged between an upper end cover and a lower end cover, an inner skeleton is arranged on the inner periphery of the filter core, and an inner frame is arranged between the upper end cover and the lower end cover There is a groove on the side of the cover facing the filter element, and glue is arranged in the groove, so that the sides at both ends of the filter element are respectively connected to the grooves of the upper end cover and the lower end cover, and a layer of sealing structure is attached above the glue. The sealing structure is a sealing gasket or a sealing coating. The filter cartridge for ensuring food safety has a simple structure, is convenient to use, can prevent glue from directly contacting food, and eliminates the hidden danger of glue to human health. At the same time, it can detect whether the glue leaks and send out an alarm signal in time.

Description

technical field [0001] The invention relates to the technical field of filter cartridges, in particular to a filter cartridge for ensuring food safety. Background technique [0002] With the development of social economy and the improvement of people's living standards, people pay more attention to health and food safety. "Food safety" has become an important factor related to national health and social stability. In the prior art, the food filter element and the end cap are connected by glue, and the food residue juice is usually weakly acidic or weakly alkaline. If the glue is soaked in such an environment for a long time, it is prone to aging and decomposition, and the decomposed small molecular organic matter is harmful to food. make an impact. [0003] In order to ensure the safety of food and prevent the small molecule organic matter decomposed from the glue from leaking into the food, the structure of the filter cartridge needs to be further improved.
