AI Technical Summary
Existing filter elements are prone to freezing and bursting due to expansion when freezing in low-temperature environments, affecting their use.
The protective shell is made of metal to enhance the structural strength of the filter element, and an observation port is provided on the shell to facilitate monitoring of the internal conditions.
This effectively reduces the probability of filter cartridges cracking due to ice expansion, allowing for timely detection and replacement of cracks, and reducing the risk of leaks.

Abstract
Claims
1. A filter cartridge housing structure for strengthening against breakage, comprising a protective casing (1) mounted on the outside of the filter cartridge, characterized in that: The protective housing (1) has a receiving cavity (2) for accommodating the filter element. The top of the receiving cavity (2) is provided with an installation port (21) for the filter element to be inserted into the outside. The protective housing (1) is made of metal material. The protective housing (1) has a first opening (3) on its side for easy observation of the internal situation. The first opening (3) extends from the receiving cavity (2) to the outside in the side position.
2. A filter cartridge housing structure for enhanced resistance to bursting according to claim 1, characterized by: Several of the first openings (3) are arranged at intervals along the length or axis of the protective shell (1).
3. A filter cartridge housing structure for enhanced resistance to bursting according to claim 2, wherein: Several of the first openings (3) are evenly spaced along a straight line.
4. A filter cartridge housing structure for enhanced resistance to bursting according to claim 1 wherein: Several of the first openings (3) are symmetrically arranged on the front and rear sides of the protective shell (1).
5. A filter cartridge housing structure for enhanced resistance to bursting as defined in Claim 1 wherein: The first opening (3) adopts a circular or elliptical hole structure.
