Detailed Implementation

[0033] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0034] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0035] This embodiment mainly describes a water tank drain filter device with a small number of load-bearing components and simplified maintenance and disassembly, as detailed below:

[0036] like Figures 1-10 As shown, the water tank drain filter includes a main body 1, a bottom cover 2, an annular cover 3, a limiting shell 4, a movable part 5, and a positioning part 6. The main body 1 and the bottom cover 2 are each provided with several drainage holes 7. A rotating shaft 11 is provided near the lower end of the main body 1. The bottom cover 2 is provided with a C-shaped connecting part 21 that rotatably connects to the rotating shaft 11. The bottom cover 2 is rotatably installed at the lower end of the main body 1. The bottom cover 2 and the main body 1 are each provided with several through drainage holes 7. The annular cover 3 is installed at the upper end of the main body 1, and the annular cover 3 and the main body 1 are each provided with a protruding rib 8 for limiting installation. The limiting shell 4 is fastened to the annular cover 3. The limiting shell 4 is set in half and clamps the movable part 5 and the positioning part 6 for installation. The positioning part 6 is fixedly installed in the limiting shell 4, and the movable part 5 is rotatably connected to the positioning part 6 through a rotating shaft 9. The limiting shell 4 restricts the separation of the movable part 5 and the positioning part 6.

[0037] In this embodiment, the movable piece 5 is integrally provided with a force receiving part 51, a rotating connecting part 52, an elastic action part 53 and a hooking part 54. The rotating connecting part 52 is connected with the hooking part 54 through a connecting section 55. The rotating connecting part 52 is located between the force receiving part 51 and the connecting section 55. The rotating connecting part 52 of the movable piece 5 is sleeved on the rotating shaft 9 to realize rotating installation. The force receiving part 51 and the connecting section 55 extend out of the limiting shell 4. The connecting section 55 is provided with an action opening 55a. One end of the elastic action part 53 is fixedly connected with the side wall of the action opening 55a, and the other end is a free end. The elastic action part 53 is provided with an arch 53a protruding from the action opening 55a. Under the elastic action of the elastic action part 53, the hooking part 54 of the movable piece 5 is buckled to the bottom cover 2 to limit the bottom cover 2 from being flipped and opened relative to the main body 1.

[0038] In this application, the movable piece 5 is integrally provided with a force receiving part, a rotating connecting part 52, an elastic action part 53 and a hooking part 54 to realize the integration of each functional part of the movable piece 5, effectively reduce the number of force receiving parts and realize the simplification during disassembly.

[0039] As shown in Figures 4-8 The side wall of the main body 1 is provided with an activity cavity 12. The activity cavity 12 is throughly arranged. The ring cover 3 is provided with an installation opening 31 communicating with the activity cavity 12. The limiting shell 4 is provided with a buckling part 41 buckling and limiting at the lower end of the installation opening 31 through the installation opening 31. The installation opening 31 is provided with a plurality of limiting strips 32 limiting the whole limiting shell 4 from entering the installation opening 31.

[0040] The positioning piece 6 is provided with a fixed part 61 clamping and fixing in the limiting shell 4. The rotating shaft 9 is connected with the fixed part 61. The fixed part 61 is concave-convex matched and limited in the limiting shell 4. The rotating connecting part 52 of the movable piece 5 and the fixed part 61 of the positioning piece 6 are located above the limiting strips 32. The connecting section 55 of the movable piece 5 passes through the installation opening 31 and is inserted into the activity cavity 12. The arch 53a on the elastic action part 53 of the connecting section 55 is elastically attached to the cavity wall of the activity cavity 12.

[0041] In order to avoid the interference between the limiting strips 32 and the connecting section 55 when the movable piece 5 rotates, the limiting strips 32 can be arranged to avoid the connecting section 55.

[0042] In order to avoid the movable piece 5 from rotating when the force receiving part 51 of the movable piece 5 is not subjected to external force, the activity cavity 12 is provided with a stopping section 13. The connecting section 55 is located between the stopping section 13 and the cavity wall of the activity cavity 12. At this time, the arch 53a of the elastic action part 53 of the movable piece 5 is elastically attached to the cavity wall of the activity cavity 12, so that the force receiving part 51 of the movable piece 5 will not shake due to rotating installation when it is not subjected to external force.

[0043] The positioning member 6 has a force-receiving part 62 that exposes the limiting shell 4. The force-receiving part 51 and the force-receiving part 62 are positioned correspondingly, and the distance between the force-receiving part 51 and the force-receiving part 62 is larger at the top and smaller at the bottom. The force-receiving part 51 and the force-receiving part 62 usually form a V-shaped structure.

[0044] like Figures 9-10 As shown, when the bottom cover 2 is unlocked and opened, the movable part 5 can rotate around the axis of the rotating shaft 9 by pinching the force-receiving part 51 and the force-receiving part 62. The elastic part 53 on the movable part 5 acts on the cavity wall of the movable cavity 12 and increases the elastic potential energy that can be reset. Furthermore, the hook part 54 on the movable part 5 deviates from the bottom cover 2 due to rotation and contacts the hook part 54 to restrict the rotation of the bottom cover 2, so that the bottom cover 2 can be flipped open to facilitate the pouring out of the residue in the main body 1.

[0045] The movable part 5 has a guide slope 56 on the hook part 54. When the bottom cover 2 is closed, it is only necessary to rotate the bottom cover 2 so that the bottom cover 2 fits against the guide slope 56 on the hook part 54. During the rotation, the bottom cover 2 can cause the movable part 5 to deflect until the bottom cover 2 rotates to the top of the hook part 54. The hook part 54 then latches and limits the bottom cover 2, and the closing operation of the bottom cover 2 is completed.
