[0026] Reference Figure 1 and Figure 2 The filter according to a first aspect of the present invention includes: a main body 110, which is provided with a water filter pipe 140, an inlet 111 and an outlet 112. The water filter pipe 140 is disposed inside the main body 110. The inlet 111 is connected to the inlet end of the water filter pipe 140, and the outlet 112 is connected to the interior of the main body 110 through the outlet end of the water filter pipe 140. The filter assembly includes a filter element 130, which is disposed inside the main body 110 and connected to the inlet end of the water filter pipe 140. Calcium sulfite particles 152 and water-repellent beads 151 are sequentially disposed inside the filter element 130, and a first filter screen 131 is disposed on the outside of the filter element 130.

[0027] Tap water enters the main body 110 through the inlet 111 and is filtered by the first filter screen 131 of the filter element 130, which removes large particles such as mud and sand. The water beads 151 remove scale from the water, preventing scale buildup and clogging of the filter element 130, thus improving the user experience. In addition, calcium sulfite filters out chlorine in the water, further improving the filtration effect.

[0028] Understandably, referring to Figure 2 The main body 110 is provided with a cover 120, and the cover 120 is provided with a connecting part 121. The connecting part 121 extends into the interior of the main body 110 and is threadedly connected to the main body 110. The cover 120 is removed, the main body 110 is opened, and the filter element 130 is inserted into the water filter pipe 140 for easy replacement. The filter element 130 is easy to install and remove. After inserting the filter element 130 into the water filter pipe 140, the filter element 130 can be replaced by tightening the cover 120, which is convenient and quick.

[0029] Understandably, referring to Figure 2 A first sealing ring 122 is provided between the connecting part 121 and the inner wall of the main body 110. The connecting part 121 extends into the main body 110 to improve the sealing performance between the cover 120 and the main body 110. Furthermore, the connecting part 121 and the inner wall of the main body 110 abut against the first sealing ring 122 to further improve the sealing performance between the cover 120 and the main body 110.

[0030] Understandably, referring to Figure 2 The cover 120 has a protruding positioning part 123 inside, and the upper end of the filter element 130 has a positioning groove 135. The positioning groove 135 matches the positioning part 123, and the positioning part 123 and the positioning groove 135 are inserted into each other. When the cover 120 is installed on the main body 110, the positioning part 123 is inserted into the positioning groove 135, and at the same time, the filter pipe 140 is used to stabilize the filter element 130 inside the main body 110, thereby improving the stability of the filter element 130.

[0031] It is understandable that a filter plug (not shown in the attached diagram) is provided between the filter element 130 and the water filter pipe 140. The filter plug is snapped between the filter element 130 and the water filter pipe 140. By removing the filter element 130, it is convenient to replace the calcium sulfite particles 152 and water beads 151 inside the filter element 130, and to prevent the calcium sulfite particles 152 and water beads 151 from flowing out of the filter element 130 after water is passed through, thus ensuring the filtration function of the filter element 130.

[0032] Understandably, referring to Figure 2 The cover 120 is transparent. After water is passed through the main body 110, the water flow can be observed through the transparent cover 120, which makes it convenient to observe the use of the filter element 130 and to replace the filter element 130 in a timely manner. It also makes the filter look more aesthetically pleasing.

[0033] Understandably, referring to Figure 2The filter element 130 has multiple filter holes 132 circumferentially. The width of the filter holes 132 is larger than the diameter of the water beads 151 or calcium sulfite particles 152, ensuring that the water beads 151 and calcium sulfite particles 152 will not clog the filter element 130 with the water flow after water is passed through. At the same time, the water beads 151 and calcium sulfite particles 152 are prevented from flowing out of the filter element 130 through the first filter screen 131 on the outside of the filter element 130.

[0034] Understandably, referring to Figure 2 The filter element 130 is provided with a plug-in portion 133, and the inner wall of the filter tube 140 is provided with a limiting portion 141 protruding from it. The plug-in portion 133 is plugged into the filter tube 140, and the plug-in portion 133 abuts against the limiting portion 141. The positioning of the filter element 130 and the filter tube 140 is achieved by the abutment of the plug-in portion 133 and the limiting portion 141, which is simple and quick.

[0035] Understandably, referring to Figure 2 A second sealing ring 134 is fitted onto the outer side of the insertion part 133, and the second sealing ring 134 abuts against the inner wall of the filter pipe 140. By setting the second sealing ring 134, the sealing performance between the filter element 130 and the filter pipe 140 is improved, thereby further improving the filtration effect of the filter.

[0036] Understandably, referring to Figure 2 The outlet 112 is equipped with an insert 220 and a connector 210. The insert 220 is snapped into the outlet 112, and the connector 210 is threadedly connected to the insert 220. By snapping the insert 220 into the outlet 112 and threading the connector 210 into the insert 220, wear on the outlet 112 is reduced, making it easier to replace worn parts. This also improves the connection strength of the connector 210 and reduces the likelihood of it loosening. A third sealing ring 211 is fitted onto the connector 210. The third sealing ring 211 abuts against the inner wall of the outlet 112, further improving the sealing performance between the connector 210 and the outlet 112.

[0037] Reference Figure 3 It is understandable that the filter element 130 is equipped with a spiral blade 136 and a second filter screen 137, with the second filter screen 137 positioned above the spiral blade 136. The second filter screen 137 is positioned above the spiral blade 136 to prevent debris from accumulating and jamming the spiral blade 136. When water flows through the filter element 130, the spiral blade 136 rotates, increasing the water contact area and improving the descaling effect.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
