Detailed implementation mode

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a detachable pipeline filter as shown in Figures 1 - 4 which includes a cylinder body 101 and a positioning mechanism. A filtering mechanism is arranged inside the cylinder body 101. The filtering mechanism includes a filter mesh basket 102. The filter mesh basket 102 is inserted into the cylinder body 101. A wrapping ring 103 is fixedly connected to the top end of the filter mesh basket 102. Through the setting of the wrapping ring 103, the deformation of the top end of the filter mesh basket 102 can be avoided, thereby improving the stability of the filter mesh basket 102 during use. A sealing mechanism is arranged between the wrapping ring 103 and the inner wall of the cylinder body 101. Connecting pipes 501 are symmetrically and fixedly connected to the outer wall of the cylinder body 101. First connecting rings 502 are fixedly sleeved at the ends of the connecting pipes 501. A plurality of connecting holes 503 are formed in one side of the first connecting ring 502. The front cross-section of the filter mesh basket 102 is trapezoidal, that is, the top opening of the filter mesh basket 102 is an inclined opening, so that the filter mesh basket 102 is higher on one side and lower on the other side. And the lower position of the filter mesh basket 102 is aligned with the connecting pipe 501 for water inlet, and the higher position of the filter mesh basket 102 is aligned with the connecting pipe 501 for water outlet. At this time, water enters the inside of the cylinder body 101 through the connecting pipe 501 for water inlet, and will directly enter the filter mesh basket 102 through the inclined opening of the filter mesh basket 102. Then, through the filtration of the inner wall of the filter mesh basket 102, the water passes through the filter mesh basket 102 and is discharged through the other connecting pipe 501 for drainage, and the filtration can be completed. At this time, the impurities filtered by the filter mesh basket 102 remain inside the filter mesh basket 102. Through the setting of the first connecting ring 502 and the connecting holes 503, it is convenient to connect the connecting pipe 501 with external equipment, so as to facilitate injecting the water to be filtered into the cylinder body 101, and then facilitating discharging the filtered water for use.

[0024] Among them, a top cover 601 is provided at the top end of the cylinder body 101. A second connecting ring 701 is fixedly connected to the top of the outer wall of the cylinder body 101. A plurality of jacks 702 are opened at the top ends of both the top cover 601 and the second connecting ring 701. A fixing bolt 703 is movably inserted through the inner walls of two adjacent jacks 702. A fixing nut 704 is threadedly sleeved on the outer wall of the fixing bolt 703 and located below the second connecting ring 701. When it is necessary to clean the impurities accumulated in the filter basket 102, turn the fixing nut 704 to separate the fixing nut 704 from the fixing bolt 703, and then pull out the plurality of fixing bolts 703 from the jacks 702, and the top cover 601 can be removed. At this time, the filter basket 102 in the cylinder body 101 can be taken out for cleaning, which improves the convenience of cleaning the filter basket 102. After the cleaned filter basket 102 is re-aligned and inserted into the cylinder body 101, then cover the top cover 601, and pass the fixing bolt 703 through the two jacks 702 and tighten it with the fixing nut 704;

[0025] In a preferred embodiment, the positioning mechanism is arranged inside the cylinder body 101. The positioning mechanism is used to prevent the filtering mechanism from rotating. The positioning mechanism includes a magnetic block 201. The magnetic block 201 is connected to the filtering mechanism. A square card hole 202 is opened at the bottom end of the magnetic block 201. A square iron block 203 is fixedly connected to the top end of the inner wall of the cylinder body 101. The outer wall of the square iron block 203 is movably inserted through the inner wall of the square card hole 202. The top end of the magnetic block 201 is fixedly connected to the bottom end of the filter basket 102. When the filter basket 102 is inserted into the cylinder body 101, at this time, align the height position of the filter basket 102 and move it downward until the square card hole 202 at the bottom end of the magnetic block 201 catches the square iron block 203. Under the limitation of the square iron block 203 by the square card hole 202, the filter basket 102 cannot rotate, and the lateral positioning of the filter basket 102 is completed. At the same time, the adsorption effect between the magnetic block 201 and the square iron block 203 makes the filter basket 102 not move when it does not receive a large longitudinal force, so as to complete the longitudinal positioning of the filter basket 102, and the filter basket 102 can work in the cylinder body 101 without displacement, which improves the stability of the filter during operation.

[0026] Among them, an inclined chamfer 301 is opened at the top of the outer wall of the square iron block 203. Through the setting of the inclined chamfer 301, the top size of the square iron block 203 is smaller, so that the square card hole 202 can easily catch the square iron block 203, thereby improving the convenience of operation of the positioning mechanism.

[0027] Among them, the sealing mechanism includes a rubber sleeve 401. The rubber sleeve 401 is sleeved on the outer wall of the edge-wrapping ring 103, and the outer wall of the rubber sleeve 401 is in interference fit with the inner wall of the cylinder body 101. When the filter basket 102 is inserted into the cylinder body 101, the rubber sleeve 401 will be located between the outer wall of the filter basket 102 and the inner wall of the cylinder body 101, so as to seal the gap between the edge-wrapping ring 103 and the cylinder body 101, avoiding water directly flowing out through the gap between the edge-wrapping ring 103 and the cylinder body 101 when there is too much water inside the cylinder body 101, ensuring that the water in the cylinder body 101 can only flow out from the connecting pipe 501 after passing through the inner wall of the filter basket 102, thereby improving the filtering effect of the filter.

[0028] Among them, an annular clamping groove 402 is formed in the inner wall of the rubber sleeve 401, and the outer wall of the edge-wrapping ring 103 is movably inserted and connected with the inner wall of the annular clamping groove 402. When the rubber sleeve 401 is sleeved on the outer wall of the edge-wrapping ring 103, the outer wall of the edge-wrapping ring 103 will be stuck inside the annular clamping groove 402, so that the rubber sleeve 401 can be stably sleeved on the outer wall of the edge-wrapping ring 103, making it difficult for the rubber sleeve 401 to separate from the edge-wrapping ring 103 during operation, thereby improving the working stability of the rubber sleeve 401.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
