DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0023] like Figures 1 to 6 As shown, a water inlet filter that is easy to install in a pipeline comprises a filter body 1 and a filter end cover 2, wherein the filter body 1 and the filter end cover 2 are detachably connected. Specifically, a first threaded boss 12 is provided on the outer side of one end of the filter body 1, and a first threaded inner groove 23 is provided on the inner side of one end of the filter end cover 2. A plurality of water inlet connecting grooves 11 are provided on the other end of the filter body 1, and an anti-slip boss 22 is provided on the other end of the filter end cover 2, wherein the first threaded boss 12 is connected to the inside of the first threaded inner groove 23. A filter screen 3 is provided between the filter body 1 and the filter end cover 2, wherein the filter screen 3 is made of plastic, and a plurality of mesh capillary pores are provided on the surface of the filter screen 3, and the filter screen 3 can filter some particulate matter and floating objects in the water, wherein the water inlet connecting groove 11 is the water inlet of the entire filter, and the anti-slip boss 22 is the water outlet of the entire filter.

[0024] In this embodiment, the anti-slip boss 22 includes an anti-slip annular boss 221 and a plurality of anti-slip vertical bosses 222. The outer portion of the anti-slip boss 22 is provided with a locking sleeve 4. The locking sleeve 4 can be made of a plastic material with a certain toughness. Whenever the external pipeline is inserted into the surface of the anti-slip boss 22, the external pipeline is located between the anti-slip boss 22 and the locking sleeve 4. In this way, the locking sleeve 4 is sleeved on the surface of the external pipeline, so that the locking sleeve 4 squeezes the external pipeline and is firmly attached to the anti-slip boss 22. Without installing a clamp, the external pipeline can be directly fixed to the surface of the anti-slip boss 22 by plugging and unplugging.

[0025] In this embodiment, a pipe joint 5 is installed inside each water inlet connection groove 11. The number of the water inlet connection grooves 11 is two, including a second threaded inner groove 111 and a third threaded inner groove 112. The diameters of the second threaded inner groove 111 and the third threaded inner groove 112 are different. The pipe joint 5 includes a quick-release joint assembly 51, a universal joint assembly 52 and a threaded joint assembly 53. The quick-release joint assembly 51 can be threadedly connected to the inside of the second threaded inner groove 111, and the universal joint assembly 52 and the threaded joint assembly 53 can be threadedly connected to the inside of the third threaded inner groove 112.

[0026] The quick-release joint assembly 51 includes a quick-release joint cover 512, a quick-release joint body 511, a return spring 514 and a steel ball 516. One end of the quick-release joint body 511 is sleeved with the quick-release joint cover 512, and the other end of the quick-release joint body 511 is provided with a second threaded boss 513. A return spring 514 is provided between the quick-release joint body 511 and the quick-release joint cover 512. A plurality of horn holes 515 are provided inside the side wall of the quick-release joint body 511, and a steel ball 516 is provided inside each of the horn holes 515. The horn holes 515 can limit the steel ball 516. 516 slides to the inside of the quick-release connector body 511, and the quick-release connector cover 512 can limit the steel ball 516 from sliding to the outside of the quick-release connector body 511. After this arrangement, the quick-release connector cover 512 is pushed downward, and the return spring 514 is deformed at this time, and the steel ball 516 has a certain range of movement inside the speaker hole 515. Then the external water inlet pipe can be directly inserted into the inside of the quick-release connector body 511. After releasing the quick-release connector cover 512, the return spring 514 will make it move upward, so that the inner side wall of the quick-release connector cover 512 can limit the movement of the steel ball 516. , so that the steel ball 516 will be squeezed with the side wall of the water inlet pipe to deform it to increase the friction force, thereby realizing the rapid installation of the water inlet pipe. Similarly, when the quick-release joint assembly 51 is installed on the filter body 1, it is only necessary to thread the second threaded boss 513 into the inside of the second threaded inner groove 111 to realize disassembly and assembly; the universal joint assembly 52 includes a universal joint body 521, a first support sleeve 522 and a threaded column 523. The first support sleeve 522 is provided inside the universal joint body 521, and the surface of the side wall of the universal joint body 521 is provided with a threaded column 523, one end of the universal joint body 521 is provided with a third threaded boss 524. After such arrangement, when the external water inlet pipeline needs to be installed, the threaded column 523 is rotated outward until the water inlet pipeline can be inserted into the universal joint body 521 and the first support sleeve 522, and then the threaded column 523 is rotated inward to continuously press the water inlet pipeline to increase the friction force, thereby realizing the rapid installation of the water inlet pipeline. When the universal joint assembly 52 is installed on the filter body 1, it only needs to thread the third threaded boss 524 into the third threaded inner groove 112 to realize disassembly and assembly;The threaded joint assembly 53 includes a threaded joint body 531 and a second support sleeve 532. The second support sleeve 532 is provided inside the threaded joint body 531. One end of the threaded joint body 531 is provided with a fourth threaded boss 533, and the other end is provided with a fourth threaded inner groove 534. After such a configuration, only the water inlet pipe with the threaded boss can be installed. The water inlet pipe is installed inside the fourth threaded inner groove 534. The second support sleeve 532 limits the distance allowed for the water inlet pipe to be inserted. When the threaded joint assembly 53 needs to be installed on the filter body 1, only the fourth threaded boss 533 is required. The threaded boss 533 is threadedly connected to the inside of the third threaded inner groove 112, so that disassembly and assembly can be achieved; the second threaded inner groove 111 and the third threaded inner groove 112 are set to adapt to pipe fixing joints 2 of different sizes, and can be inserted into the second threaded inner groove 111 or the third threaded inner groove 112 according to different diameters. Moreover, whether it is connected to the inside of the second threaded inner groove 111 or the third threaded inner groove 112, the second threaded inner groove 111 can allow water to pass through, which will not affect the normal use of the entire filter body 1, bringing convenience to users when installing pipelines. ;

[0027] Working principle and usage of this utility model:

[0028] For the water inlet end of the entire filter, the second threaded inner groove 111 or the third threaded inner groove 112 can be inserted into the inside according to different diameters, so that the second threaded inner groove 111 and the third threaded inner groove 112 can adapt to pipe fixing joints 2 of different sizes. For the water outlet end of the entire filter, after the external pipe is inserted into the surface of the anti-slip annular boss 221 and the anti-slip vertical boss 222, the locking sleeve 4 is sleeved on the surface of the external pipe, so that the locking sleeve 4 squeezes the external pipe so that it is firmly attached to the anti-slip boss 22. Without installing a clamp, the external pipe can be directly fixed to the surface of the anti-slip boss 22 by plugging and pulling.

[0029] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
