DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.

[0021] Please refer to Figures 1-4This utility model provides a technical solution: a stainless steel long-handled filter head, including a filter rod 1 and a filter cap 3. The top of the filter rod 1 is provided with a mounting plate 2, which has an annular structure and a through hole communicating with the filter rod 1. The bottom of the filter cap 3 is provided with an insertion tube 301, which is inserted into the through hole. Four L-shaped blocks 201 are evenly distributed on the top of the mounting plate 2, and limiting holes 202 are formed on the L-shaped blocks 201. A limiting ring 302 is provided on the outer side of the bottom of the filter cap 3, and four grooves 303 corresponding to the L-shaped blocks 201 are formed on the limiting ring 302, which is positioned between the four L-shaped blocks 201. Four protrusions 304 are provided on the outside of the filter cap 3, and sliding holes 305 are formed at the upper and lower ends of the protrusions 304 respectively. The protrusion 304 has a groove 306 inside, which communicates with the sliding hole 305. A pull rod 308 is fitted in the sliding hole 305. The pull rod 308 is a long strip structure. A slider 309 is provided on the outside of the pull rod 308. The slider 309 is a square structure and fits in the groove 306. A spring 3010 is sleeved on the outside of the pull rod 308. One end of the spring 3010 is connected to one end of the slider 309, and the other end is connected to the top of the groove 306. The bottom end of the pull rod 308 is inserted into the limiting hole 202. One side of the bottom end of the pull rod 308 is designed with a bevel structure to facilitate applying pressure to the pull rod 308 to compress it and make it shrink. The top of the four pull rods 308 is provided with a pull plate 307, which is a circular structure.

[0022] The pull plate 307 drives the pull rod 308 to move, and pulls one end of the pull rod 308 out of the limiting hole 202 to release the limiting of the L-shaped block 201. Then, the filter cap 3 is rotated to rotate the groove 303 to the corresponding position of the L-shaped block 201, so that the filter cap 3 can be disassembled and replaced. This solves the problem of wasting resources by replacing the entire long-handled filter head.

[0023] The top outer side of the filter rod 1 is provided with an external thread 101, through which the long-handled filter head can be installed on the filter plate.
