DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0020] like Figures 1 to 4As shown, a filter with an easily disassembled joint comprises a filter assembly 1, a joint body 2 arranged on one side of the filter assembly 1, the interior of the joint body 2 allows external pipes to be inserted, the filter assembly 1 and the joint body 2 are detachably connected, one end of the joint body 2 is provided with a first threaded boss 22, and the first threaded boss 22 is detachably connected to the interior of the filter assembly 1. Specifically, the filter assembly 1 comprises a filter body 11, a filter end cover 12 and a filter screen 13, one end of the filter body 11 is provided with a first threaded inner groove 111, the first threaded boss 22 is detachably connected to the interior of the first threaded inner groove 111, the other end of the filter body 11 is detachably connected to the filter end cover 12, and the filter screen 13 is arranged in the interior of the filter body 11. After such arrangement, the entire filter assembly 1 is detachably designed, which is convenient for later disassembly and assembly and replacement of parts. The interior of the filter body 11 is provided with a plurality of first limiting bosses 112, and the interior of the filter end cover 12 is provided with a plurality of first limiting bosses 112. The second limiting boss 121 is provided, and a boss limiting groove 122 is formed between adjacent second limiting bosses 121. The inner wall between the plurality of first limiting bosses 112 limits one end of the filter screen 13, and the boss limiting groove 122 limits the other end of the filter screen 13. After this arrangement, the two ends of the filter screen 13 are fixed by the boss limiting groove 122 and the first limiting boss 112 to prevent the filter screen 13 from shaking when the water flows through the filter body 11. The surface of the filter end cover 12 is provided with an end cover boss 123. The surface of the end cover boss 123 is provided with an anti-skid plug-in structure 14, and the inner wall of the external pipeline is used to be plugged into the surface of the end cover boss 123. The anti-skid plug-in structure 14 includes a plurality of anti-skid annular bosses 141 and a plurality of anti-skid vertical bosses 142. After such arrangement, whenever the external pipeline is plugged into the surface of the end cover boss 123, the anti-skid annular boss 141 and the anti-skid vertical boss 142 are used to increase the friction force of the inner wall of the inserted pipeline, thereby realizing the rapid plug-in and pull-out installation of the pipeline, and it can also be quickly locked with a clamp after installation.

[0021] In this embodiment, a sealing gasket 15 is provided between the filter assembly 1 and the joint body 2. This arrangement is to achieve a sealed connection between the filter assembly 1 and the joint body 2 so that water will not leak out from the connection point. The outside of the joint body 2 is slidably covered with a joint shell 3, and the outside of the joint shell 3 is provided with a plurality of first anti-slip bosses 31, and the outer surface of the joint body 2 is provided with a plurality of second anti-slip bosses 21. The internal arc-shaped groove 23 of the joint body 2, the inside of the arc-shaped groove 23 is provided with an elastic rubber 24, and the elastic rubber 24 will be deformed after the external pipeline is inserted into the inside of the joint body 2. A reset spring 25 is provided between the joint shell 3 and the joint body 2, and the inner wall surface of the joint body 2 is provided with a plurality of trumpet holes 26, and the inside of the trumpet holes 26 is provided with steel balls 27. The trumpet holes 26 are used to limit the steel balls 27 from sliding into the inside of the joint body 2, and the joint shell 3 is used to limit the steel balls 27 from sliding into the joint body 2. After such arrangement, when the user disassembles and assembles the joint body 2, the second anti-slip boss 21 can be used to increase the friction force so as to rotate the entire joint body 2. When it is necessary to insert a pipeline into the interior of the joint body 2, the first anti-slip boss 31 can be used to increase the friction force so as to move the entire joint shell 3 downward. When the joint shell 3 moves downward, the steel ball 27 is squeezed by the joint shell 3 and the pressure will gradually decrease. Since the trumpet hole 26 is a small hole toward the inside of the joint body 2 and a large hole toward the outside of the joint body 2, after the joint shell 3 moves downward, the steel ball 27 can have a movable gap in the trumpet hole 26. At this time, the external pipeline can be easily inserted into the interior of the joint body 2. Then the joint shell 3 is loosened, and the joint shell 3 will be driven to move upward under the elastic force of the reset spring 25. Due to the squeezing of the inside of the joint shell 3, the steel ball 27 gradually moves into the inside of the joint body 2 until it presses the outer wall of the inserted pipeline. In order to enhance the friction force, the elastic rubber 24 will also deform to increase the friction force.

[0022] Working principle and usage of this utility model:

[0023] First, both ends of the entire filter assembly 1 need to be connected to the water circuit. For the water outlet, when the external pipe is plugged into the surface of the end cover boss 123, the anti-skid annular boss 141 and the anti-skid vertical boss 142 are used to increase the friction of the inner wall of the inserted pipe, thereby realizing the quick plug-in and pull-out installation of the pipe, and the clamp is also used to lock it after installation. For the water inlet, the second anti-skid boss 21 is used to increase the friction so as to rotate the entire joint body 2, so that the first threaded boss 22 can be detachably connected to the inside of the first threaded inner groove 111, and then the pipe is inserted into the inside of the joint body 2, and the first anti-skid boss 31 is used to increase the friction so as to move the entire joint shell 3 downward. When the joint shell 3 moves downward, the steel ball 27 is affected. The extrusion of the joint shell 3 will gradually decrease. Since the trumpet hole 26 is a small hole toward the inside of the joint body 2 and a large hole toward the outside of the joint body 2, the steel ball 27 can have a movable gap in the trumpet hole 26 after the joint shell 3 moves downward. At this time, the external pipeline can be easily inserted into the inside of the joint body 2. Then loosen the joint shell 3, and the joint shell 3 will be driven to move upward under the elastic force of the reset spring 25. Due to the extrusion from the inside of the joint shell 3, the steel ball 27 gradually moves into the inside of the joint body 2 until it presses the outer wall of the inserted pipeline. In order to enhance the friction, the elastic rubber 24 will also deform to increase the friction. The entire filter assembly 1 is designed to be detachable, which is convenient for later disassembly and replacement of parts.

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.
