BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a cross-sectional view of a telescopic water filter box of the utility model. DETAILED DESCRIPTION

[0014] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0015] Please refer to Figure 1 A telescopic water filter box according to an embodiment of the utility model is characterized in that it comprises a water filter box body 1, an extension tube 2 and a filter element 3, the left end of the water filter box body 1 is fixedly and sealedly connected with the water pipe, the extension tube 2 is arranged on the right side of the water filter box body 1, and the filter element 3 is arranged inside the water filter box body 1;

[0016] The right end of the water filter box 1 is the water outlet 4 of the water filter box 1. The water outlet 4 is a double-layer pipe structure. The inner pipe of the water outlet 4 is sealed and connected to the inner wall of the water filter box 1. A sealing gasket 5 is provided at the leftmost end of the outer pipe of the water outlet 4. The sealing gasket 5 connects the outer pipe of the water outlet 4 with the inner pipe.

[0017] The extension tube 2 is slidably arranged on the outside of the water outlet 4, and the extension tube 2 covers the water outlet 4 of the water filter box 1. The extension tube 2 is also a double-layer pipe structure. The inner pipe of the extension tube 2 is clamped between the double-layer pipes of the water outlet 4. The inner wall of the outer pipe of the extension tube 2 is provided with an internal thread, and the outer wall of the outer pipe of the water outlet 4 is provided with an external thread. The extension tube 2 is threadedly connected to the water outlet 4;

[0018] The filter element 3 is a multi-stage filter element 3 , and the filter element 3 is arranged at the center of the water filter box 1 .

[0019] The length of the water filter box can be adjusted and extended by the extension tube 2 set at the water outlet 4 to avoid the problem of being unable to install due to inappropriate size. When the size is too large, the extension tube 2 is threadedly rotated to the left to retract the extension tube 2 into the water outlet 4. When the size is too small, the extension tube 2 is threadedly rotated to the right to extend the extension tube 2 out of the water outlet 4. The length of the entire water filter box can be flexibly adjusted to match a variety of scenarios.

[0020] Preferably, the gap between the inner pipe and the outer pipe of the water outlet 4 is adapted to the width of the inner pipe of the extension tube 2 .

[0021] The water outlet 4 and the extension tube 2 are nested with each other to prevent the water in the water filter box 1 from flowing out from the gap between the water outlet 4 and the extension tube 2, and the sealing gasket 5 set at the leftmost end of the pipe outside the water outlet 4 can also effectively seal the water filter box 1.

[0022] Preferably, a sealing flange 7 is provided at the rightmost end of the extension tube 2, and the sealing flange 7 is sealed and connected to the water meter. The sealing flange 7 is used to seal the water meter and the extension tube 2 as a replacement for the connection between the water outlet 4 and the water meter. The sealing flange 7 at the rightmost end of the extension tube 2 is sealed and connected to the water meter to prevent water from leaking from the connection between the extension tube 2 and the water meter.

[0023] Preferably, the filter element 3 is composed of multiple filter plates 6, which are inclined toward the water outlet 4. The four sides of the filter plates 6 are clamped with the inner wall of the water filter box 1. Compared with conventional filter plates, multiple filter plates 6 have better filtering effect.

[0024] Preferably, the mesh number of the filter plate 6 gradually increases from left to right. The filter plate 6 with gradually increasing mesh number can effectively filter various sizes of debris in the water in layers. The filter plate 6 with a smaller mesh number is used to filter large particles of impurities first, and the smaller impurities are then filtered by the filter plate 6 with a larger mesh number, thereby achieving classified filtration and avoiding the situation where the entire water filter box 1 is blocked quickly.

[0025] As described above, when the utility model is actually used, the left end of the water filter box 1 is sealed and connected to the water pipe, and then the extension tube 2 is rotated a certain length until the length of the entire water filter box is appropriate, and the sealing flange 7 fixedly arranged at the rightmost end of the extension tube 2 is sealed and fixedly connected to the water meter, and the installation of the entire water filter box can be completed, avoiding the situation where additional welding and fixing are required due to inappropriate size, and the installation is time-saving and labor-saving.

[0026] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any changes and modifications made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
