[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a shower head filter element that is easy to replace, including a shower head body 1 and a composite filter element body 2. The composite filter element body 2 is provided inside the shower head body 1 to filter the water flowing inside the shower head body 1.

[0025] The composite filter body 2 has a docking groove 201 and an insertion groove 202 inside, and the insertion grooves 202 are equally spaced inside the composite filter body 2. A docking block 3 is inserted into the docking groove 201. An insertion block 401 is inserted into each of the multiple insertion grooves 202, and the outer sides of the multiple insertion blocks 401 are equally spaced to the locking blocks 4. The locking blocks 4 and the reserved grooves inside the shower body 1 are both semi-arc-shaped. The outer side of the locking blocks 4 is inserted into the reserved groove inside the shower body 1. The side of the docking groove 201 closer to the shower body 1 is arc-shaped, and the side of the docking block 3 away from the shower body 1 is arc-shaped, so as to facilitate the insertion of the docking groove 201 and the docking block 3.

[0026] In practice, to facilitate the replacement of the shower head filter, the composite filter body 2 has a docking groove 201 and an insertion groove 202 inside, which are respectively inserted into the docking block 3 and the insertion block 401. When disassembling the composite filter body 2, the composite filter body 2 is moved outward by the locking block 4, which causes the docking groove 201 inside the composite filter body 2 to completely disengage from the docking block 3. After the composite filter body 2 is completely removed from the shower head body 1, the composite filter body 2 is pushed upward by the insertion of the insertion block 401 and the insertion groove 202, thus removing the composite filter body. 2. Successfully remove the filter from the locking block 4. At this time, insert the new composite filter body 2 into the locking block 401 inside the locking block 4 through the inner insertion groove 202. Insert the locking block 4 into the reserved groove inside the shower body 1 again. At this time, the docking groove 201 inside the new composite filter body 2 will be inserted into the docking block 3, thus completing the replacement of the composite filter body 2. This easy-to-replace shower filter does not require the entire shower body 1 to be disassembled. Simply remove the locking block 4 and the composite filter body 2 to replace the composite filter body 2. The operation is convenient.

[0027] See Figures 3-6 It is known that the locking block 4 and the shower body 1 are both connected to the outer side with connecting threads 5, and the locking block 4 and the outer side of the shower body 1 are threadedly connected to the inner thread sealing sleeve 501 through the connecting threads 5. The shower body 1 has a sealing groove 502 inside. The bottom and inner side of the inner thread sealing sleeve 501 are respectively bonded with a sealing ring 503 and a sealing ring 504, and the bottom of the inner thread sealing sleeve 501 and the sealing ring 503 are inserted into the sealing groove 502. The inner side of the sealing ring 504 is in contact with the outer surface of the shower body 1. The upper side of the inner thread sealing sleeve 501 has a positioning hole 505. A mounting post 602 is welded to one side of the shower body 1. A return spring 601 is connected inside the mounting post 602. One side of the return spring 601 is connected to the positioning block 6. The two ends of the positioning block 6 are respectively inserted into the mounting post 602 and the positioning hole 505.

[0028] In specific implementation, to enhance the connection effect between the locking blocks 4, after the locking blocks 4 are inserted into the reserved groove inside the shower body 1, the internal threaded sealing sleeve 501 is threadedly connected to the locking blocks 4 and the shower body 1 through the connecting thread 5 until the bottom of the internal threaded sealing sleeve 501 is tightly inserted into the sealing groove 502 through the sealing ring 1 503. At this time, the sealing ring 2 504 will enhance the sealing effect after the upper side of the internal threaded sealing sleeve 501 is connected to the shower body 1. In addition, the positioning block 6 inserted inside the mounting post 602 will be pushed by the return spring 601 and inserted into the positioning hole 505 opened inside the internal threaded sealing sleeve 501 to limit the position of the internal threaded sealing sleeve 501. This convenient shower filter element has an internal threaded sealing sleeve 501 with enhanced sealing effect and a positioning block 6 to limit the position of the internal threaded sealing sleeve 501 on the outside of the locking block 4. The installation effect of the composite filter element body 2 is better when used.

[0029] In summary, when using this easy-to-replace shower head filter, push the positioning block 6 into the positioning hole 505 until the positioning block 6 disengages from the positioning hole 505. Then, rotate the internal threaded sealing sleeve 501 to move it upward through the threaded connection between the internal threaded sealing sleeve 501 and the connecting thread 5. At this time, the locking block 4 can be moved to the outside of the shower head body 1, thereby smoothly removing the composite filter body 2 inside the shower head body 1.
