[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a filter element with an impurity temporary storage mechanism, according to... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a filter screen plate 2 is provided in the middle of the outer shell 1, and an extension sleeve 14 is provided on the outer shell 1 outside the filter screen plate 2. A positioning seat 15 on one side of the extension sleeve 14 is detachably connected to one end of the drain pipe 16. A detector 17 is provided in the middle of the front of the extension sleeve 14. The detector 17 is specifically an optical particle counter, which facilitates the detection of impurity content inside the filter element body 3, so as to discharge impurities in a timely manner. The filter element body 3 is provided in the middle of the inner shell 1, and an inlet pipe 4 is provided in the middle of the upper end of the filter element body 3. The top of the inlet pipe 4 passes through the middle of the upper end of the outer shell 1 and extends to the outside of the outer shell 1. A sealing sleeve 5 is provided at the connection between the inlet pipe 4 and the middle of the upper end of the outer shell 1, and an installation flange 6 is detachably connected to the outer side of the inlet pipe 4 above the sealing sleeve 5. A stainless steel base plate 7 is provided at the bottom of the lower end of the filter element body 3, and a one-way drain valve 8 is provided in the middle of the lower end of the stainless steel base plate 7. The one-way drain valve 8 facilitates the transport of impurities to the storage box 9, preventing them from flowing back into the filter element body 3. The bottom center of the lower end of the outer shell 1 is threaded to the top outer side of the storage box 9. A sealing ring 101 is provided on the upper part of the storage box 9, outside the filter element body 3 and the stainless steel base plate 7. The outer side of the sealing ring 101 is also in contact with the lower end of the inner shell 1. The sealing ring 101 improves the sealing between the lower outer side of the filter element body 3 and the outer shell 1. An observation window 901 is provided in the center of the front of the storage box 9, and a sealing gasket 10 is provided between the upper outer side of the storage box 9 and the bottom of the outer shell 1. The sealing gasket 10 improves the sealing at the connection between the storage box 9 and the outer shell 1. A guide rubber seat 11 is provided inside the upper end of the storage box 9 to guide impurities into the storage box 9. At the same time, a rubber cover 13 is provided at the bottom end of the drain pipe 12 at the lower end of the storage box 9.

[0021] Specifically, the filter element body 3 includes an outer mesh cylinder 301, an inner mesh cylinder 302, a filter layer 303, and an anti-stick coating 304. The filter layer 303 is disposed between the outer mesh cylinder 301 and the inner mesh cylinder 302. The liquid is filtered multiple times through the outer mesh cylinder 301, the inner mesh cylinder 302, and the filter layer 303 to improve the filtration effect. At the same time, the inner side of the inner mesh cylinder 302 is provided with an anti-stick coating 304, which is made of Teflon material. This makes it difficult for impurities to adhere to the inner wall of the filter element body 3. It can be cleaned with water without disassembly, which improves the convenience of cleaning operations and also extends the life of the filter element body 3.

[0022] To further explain, the filter holes of the outer mesh cylinder 301 and the inner mesh cylinder 302 have the same diameter, and the filter hole diameters of the outer mesh cylinder 301 and the inner mesh cylinder 302 are smaller than the filter hole diameters of the filter screen plate 2.

[0023] In use, liquid enters the filter element body 3 through the inlet pipe 4, and after being filtered by the filter element body 3, the liquid enters the cavity between the outer shell 1 and the filter element body 3. Then, the liquid is filtered again by the filter screen 2 and enters the expansion sleeve 14. Finally, it is discharged through the drain pipe 16. Due to the reduced flow rate, impurities are deposited at the lower end of the filter element body 3. The impurities inside the filter element body 3 are monitored by the detector 17. When a certain thickness is reached, the one-way drain valve 8 is opened, allowing the deposited impurities to enter the temporary storage box 9 for temporary storage. The condition of the impurities stored in the temporary storage box 9 can be easily viewed through the observation window 901. Finally, the rubber cover 13 is opened, allowing the impurities stored in the temporary storage box 9 to be discharged through the drain pipe 12.
