DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 The foldable, washable and reusable filter element comprises a support rod 1, the upper part of which is formed by combining two cylindrical rods together, and the lower part is a rectangular plate.

[0022] A rotating plate 2 is installed on the support rod 1 through a first connecting mechanism. The first connecting mechanism includes a first connecting rod 14 installed on the rotating plate 2. A first connecting groove corresponding to the first connecting rod 14 is provided on the support rod 1. As shown in the figure, after the first connecting rod 14 is inserted into the first connecting groove, the rotating plate 2 can rotate relative to the support rod 1.

[0023] The rotating plate 2 is provided with a gear 9 through the mounting groove 8, the support rod 1 is provided with a slide bar through the lifting groove 12, and the slide bar is provided with a movable frame 10 through a dragging mechanism. The dragging mechanism includes a dragging spring 13 sleeved on the outside of the slide bar, and the two ends of the dragging spring 13 are elastically connected to the outer wall of the movable frame 10 and the inner wall of the lifting groove 12 respectively. The movable frame 10 cooperates with the gear 9 through the meshing mechanism, and the meshing mechanism includes a fixed rack 11 installed on the movable frame 10, and the fixed rack 11 cooperates with the gear 9. The dragging spring 13 realizes the upward dragging operation of the movable frame 10, ensuring that the fixed rack 11 on the movable frame 10 can mesh with the gear 9, thereby preventing the gear 9 and the rotating plate 2 from rotating, and playing a role of limiting.

[0024] A contact plate 3 is connected between the two rotating plates 2 via a second connecting mechanism. The second connecting mechanism includes a second connecting rod installed on the rotating plate 2. A second connecting groove 15 corresponding to the second connecting rod is provided on the contact plate 3. As shown in the figure, when the second connecting rod is in the second connecting groove 15, the rotating plate 2 rotates relative to the support rod 1, thereby realizing the synchronous rotation of the contact plate 3. As shown in the figure, the surface where the contact plate 3 contacts the outer wall of the support rod 1 is designed to be arc-shaped.

[0025] A fixed plate 4 is also provided between the two rotating plates 2, and fixing grooves 16 are provided at both ends of the fixed plate 4. A fixed block 17 is provided on the rotating plate 2, and an upper groove 18 is provided on the fixed block 17. A positioning block 7 is provided in the upper groove 18 through an upper mechanism. The upper mechanism includes an upper spring 19 installed in the upper groove 18, and both ends of the upper spring 19 are elastically connected to the inner wall of the upper groove 18 and the outer wall of the positioning block 7 respectively. The upper spring 19 realizes the upper push of the positioning block 7, which can be pushed into the positioning hole 6. At this time, the two rotating plates 2, the fixed plate 4 and the contact plate 3 form a rectangular frame, and the filter medium 5 is installed in the rectangular frame.

[0026] The fixed plate 4 is provided with a positioning hole 6, and a filter medium 5 is installed between the two rotating plates 2, the contact plate 3 and the fixed plate 4. The filter medium 5 can be fiber, membrane, etc., for intercepting impurities, which can be determined according to its specific usage.

[0027] When the utility model is used, the movable frame 10 is dragged downward to make it slide downward on the slide rod. At this time, the drag spring 13 is in a stretched state, and the movable frame 10 descends to drive the fixed rack 11 to disengage from the gear 9. Then the gear 9 loses its limit fixation, and the rotating plate 2 and other components can rotate relative to the support rod 1, changing from a vertical contact state to a horizontal separation state, and can be unfolded for use, and filtering operation can be performed through the filter medium 5.

[0028] In the present solution, the positioning block 7 in the positioning hole 6 is pressed to squeeze the upper spring 19, and then the rotating plate 2 is moved laterally relative to the fixed plate 4. The rotating plate 2 will be separated from the contact plate 3 and the fixed plate 4, and the connection between the frame is released, so that the multiple components of the device are dispersed, which can facilitate the replacement of damaged parts. At the same time, the filter medium 5 is completely disassembled, which can be easily cleaned and reused.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
