[0029] Specifically, the filter body 1 supports and protects the components of the device, the upper cup body 12 accesses and discharges the water source through the water inlet 121 and the water outlet 122, the filter element 2 is fixed by the upper cup body 12 and the top cover 13, so that the filter element 2 can be kept stable, the water inlet 121 puts the water source into the lower cup body 11, and the water source is filtered by the filter element 2, and the filtered water source surges upward in the filter element 2, so that the water source can reach the water outlet 122 position for discharge, realizing filtration, the top cover 13 supports the lead screw 3, the driving motor 32 rotates and drives the lead screw 3, the lead screw 3 supports and drives the lifting plate 31 to ascend and descend, when the filter element 2 is cleaned, the closing valve 141 is controlled to open, so that the impurity discharge pipe 14 can discharge the water source, the water source washes the surface of the filter element 2 to drive impurities to be discharged through the impurity discharge pipe 14, and then the driving motor 32 is controlled to drive the lead screw 3 to rotate, so that the lead screw 3 can drive the lifting plate 31 to slide up and down, and the lifting plate 31 reciprocally pushes the water source in the filter element 2 up and down while sliding, so that the water source in the lower cup body 11 can exchange and flow in and out of the filter element 2, and when the water source is pushed by the lifting plate 31 from the inside of the filter element 2 to the outside of the filter element 2, the water source can reversely wash the impurities intercepted on the outside of the filter element 2, increase the pressure of the water source in the lower cup body 11, and then increase the impact force of the water source on the filter element 2, make up for the deficiency of the traditional single water flow washing capacity, and then improve the cleaning effect of the filter element 2.

[0030] In an embodiment of the present application, as shown in Figure 2 and Figure 4 The upper cup body 12 is provided with an annular groove 15 and a plurality of water outlet holes 151, the water inlet 121 is in communication with the internal space of the annular groove 15, the annular groove 15 conveys the water source in the internal space of the upper cup body 12 through the plurality of water outlet holes 151, the plurality of water outlet holes 151 are arranged in a circumferential array, and the inner walls of the plurality of water outlet holes 151 are each provided with a one-way valve 152.

[0031] It should be noted that the one-way valve 152 described in this embodiment has an opening facing the internal space of the lower cup body 11.

[0032] Specifically, the water inlet 121 delivers the water source into the annular groove 15, the annular groove 15 uniformly distributes the water source into a plurality of water outlets 151 by the annular design, the water outlets 151 are inclined to the outside of the filter core 2, so that the water outlets 151 can uniformly distribute the water source to the outside of the filter core 2, reduce the situation that the impurities in the water source are distributed in a single position and cause the filter core 2 to be partially blocked, and facilitate the subsequent washing work when the filter core 2 is cleaned, and the one-way valve 152 reversely blocks the water source to prevent backflow.

[0033] In an embodiment of the present application, as shown in Figure 2 The connecting hole 131 is arranged in the top cover 13 and corresponds to the water outlet 122.

[0034] It should be noted that the size of the top cover 13 described in this embodiment is greater than the opening diameter of the water outlet 122, which increases the fault tolerance.

[0035] Specifically, the filtered water source flows upward from the inside of the filter core 2 into the top cover 13, the connecting hole 131 guides the water source into the water outlet 122, and the filtered water source is circulated.

[0038] Specifically, the lead screw 3 supports the bottom plate 33, the bottom plate 33 and the top cover 13 support the two limiting rods 34, and the rotating relationship between the bottom plate 33 and the lead screw 3 ensures that the lead screw 3 is not affected by the bottom plate 33 when rotating, the two limiting rods 34 cannot rotate due to the limiting of the top cover 13, and thus the two limiting rods 34 can limit and guide the sliding of the lifting plate 31, prevent the lifting plate 31 from rotating, and ensure the stability of the driving of the lifting plate 31 by the lead screw 3.

[0039] In an embodiment of the present application, as shown in Figures 2-4 The two pressure sensors 4 are installed on the bottom end of the top cover 13, the spherical rolling body 41 is rotatably connected to the bottom end of the two pressure sensors 4, and the spherical rolling body 41 is in sliding connection with the top end of the extension ring 21.

[0041] Specifically, the top cover 13 supports the two pressure sensors 4, and the pressure sensors 4 are in contact with the extension ring 21 through the spherical rolling body 41. When the device is used, the top cover 13 extrudes and fixes the extension ring 21, the pressure sensor 4 is contracted by the reaction force of the extension ring 21, and when the top cover 13 rotates with the pressure sensor 4, the pressure sensor 4 rotates and slides on the top of the extension ring 21 through the spherical rolling body 41, reducing the frictional resistance and loss between the pressure sensor 4 and the extension ring 21. When the top cover 13 and the upper cup body 12 are loose, the pressure sensor 4 is extended, so that the pressure sensor 4 can be in time to sense and timely transmit reminder information to the personnel, preventing water leakage.

When used, the water inlet 121 delivers the water source into the annular groove 15, the annular groove 15 uniformly distributes the water source into the plurality of water outlet holes 151 by utilizing the annular design, the water outlet holes 151 can uniformly distribute the water source to the outside of the filter element 2, reducing the situation that the impurities in the water source are distributed in a single position and cause local blockage of the filter element 2. The filtered water flows upward to the connecting hole 131 position, the connecting hole 131 guides the water source into the water outlet 122, realizing circulation of the filtered water. When the filter element 2 is cleaned, the lifting plate 31 is controlled to slide up and down, so that the lifting plate 31 can reciprocatingly push the water source in the lower cup body 11 up and down, thereby increasing the water pressure, so that the water source in the lower cup body 11 can exchange and flow in and out of the filter element 2. When the water source is pushed by the lifting plate 31 from the inside of the filter element 2 to the outside of the filter element 2, the water source can reversely flush the impurities intercepted on the outside of the filter element 2, increase the pressure of the water source in the lower cup body 11, and thereby increase the impact force of the water source on the filter element 2, making up for the deficiency of the traditional single water flow flushing capacity, and thereby improving the cleaning effect of the filter element 2.
