[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an external filter connector for a faucet. Example

[0030] Combination Figures 1 to 5 As shown, the present invention provides an external filter connector for a faucet, including two replaceable filter elements 300, a faucet stabilizing component 100 installed on the faucet, and a filter component 200 installed in the faucet stabilizing component 100. The faucet stabilizing component 100 is fixed on the faucet tube and provides a support platform for the filter component 200. The filter component 200 is used to provide a replacement platform for the two replaceable filter elements 300.

[0031] The faucet stabilization assembly 100 includes a clamp 110 and two springs 1101, two clamping plates 120 movably installed outside the clamp 110, a rod sleeve 1201 installed inside the two clamping plates 120, a support rod 130 inserted into the rod sleeve 1201, a load-bearing plate 140 fixedly installed at the bottom of the support rod 130, and a core pad 150 movably installed on the load-bearing plate 140.

[0032] The clamping plate 120 has a sliding groove inside, and the clamp 110 has a plug fixedly installed inside, and the plug is adapted to pass through the sliding groove.

[0033] Two load-bearing plates 140 are respectively set in the sliding grooves inside the two clamping plates 120;

[0034] The outer wall of the sleeve 1201 is provided with a threaded transverse hole, and a locking bolt 1202 is fitted into the threaded transverse hole.

[0035] The core pad 150 has a triangular structure, and three cylindrical holes are opened inside the core pad 150. A rubber inner pad is fixedly installed on the inner wall of the cylindrical holes.

[0036] The filter assembly 200 includes a sealed filter sleeve 210 installed in the load-bearing plate 140, a main filter element 220 installed at the bottom of the sealed filter sleeve 210, a drain filter sleeve 230 installed at the bottom of the main filter element 220, and an anti-seepage inner ring 240 disposed in the drain filter sleeve 230.

[0037] Replacement filter 300 is installed inside core pad 150.

[0038] Depending on the length of the faucet pipe, the locking bolt 1202 is loosened in advance. Then, the support rod 130 is controlled to rise and fall along the inside of the rod sleeve 1201. The load-bearing plate 140 and the core pad 150, which rise and fall synchronously with the support rod 130, will then be adapted to the faucet port.

[0039] After the sealed filter sleeve 210 is removed from the faucet port, under the elastic support of the two springs 1101, the two clamps 120 and the rod sleeve 1201 will quickly extend outward, allowing the filter assembly 200 and the two replacement filter elements 300 to open a sufficiently large gap from the faucet port, thus facilitating quick cleaning of the filter assembly 200. Example

[0040] Combination Figure 4 and Figure 5 As shown, based on Embodiment 1, the filter assembly 200 further includes two expansion pads 2402, and the two expansion pads 2402 are adapted to be snapped into two slots on the outer wall of the seepage-proof inner ring 240.

[0041] A T-shaped sliding column is fixedly installed at the top of the screw 2303, and a slot 2401 is opened at the bottom of the anti-seepage inner ring 240, and the T-shaped sliding block is adapted to be inserted into the inside of the slot 2401.

[0042] The outer wall of the drainage filter sleeve 230 is provided with a groove 2301, and the top of the drainage filter sleeve 230 is provided with an annular groove, a screw sleeve 2302 is fixedly installed inside the annular groove, and a screw rod 2303 is movably installed inside the screw sleeve 2302.

[0043] Preferably, the expansion pad 2402 has a cylindrical cross-section, and the end of the screw 2303 that penetrates into the groove 2301 is fixedly fitted with a hexagonal end;

[0044] Specifically, when the screw 2303 rotates forward, the anti-seepage inner ring 240 is pulled by the screw 2303 and will quickly contract towards the inside of the drainage filter sleeve 230. When the screw 2303 rotates in reverse, the anti-seepage inner ring 240 is pushed upward, which can quickly clamp and fix the replacement filter element 300 after replacement.

[0045] The working principle and usage process of this utility model are as follows: First, insert the clamp 110 along the water outlet pipe of the faucet until the clamp 110 rises to the designated position along the faucet pipe body. Then, press the support rod 130 toward the faucet and then insert the sealing filter sleeve 210 toward the bottom of the faucet.

[0046] When the filter assembly 200 is fully connected to the faucet outlet, the faucet is turned on and drains water outward. The water after passing through the faucet will flow into the main filter element 220 through the sealed filter sleeve 210. Finally, the water will be filtered by the main filter element 220 and enter the inner cavity of the drain filter sleeve 230.

[0047] After prolonged use of the main filter element 220, to reduce the difficulty of disassembling the external filter, the screw 2303 is reversed using a screwdriver. As the screw 2303 extends downward along the inside of the screw sleeve 2302, the anti-seepage inner ring 240, which is engaged at the top of the screw 2303, will retract into the annular groove on the inner wall of the drainage filter sleeve 230. At this time, the main filter element 220 will be loosened. Then, the core pad 150 is rotated until one of the replacement filter elements 300 in the core pad 150 rotates into the gap between the sealing filter sleeve 210 and the drainage filter sleeve 230. Then, the screw 2303 is adjusted to rotate forward, and the reset anti-seepage inner ring 240 will quickly lock the replacement filter element 300.

[0048] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
