[0047] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0048] Figure 1 This is a structural schematic diagram of a pre-filter anti-clogging point-shaped water distributor according to an embodiment of the utility model. Figure 2 is based on Figure 1 A magnified schematic diagram of area A in the middle. Figure 3 This is a schematic diagram of the connection between the filter screen and the strip plate in the pre-filter anti-clogging point-shaped water distributor according to an embodiment of the utility model. Figure 5 This is a schematic diagram of the structure inside the filter tube in the pre-filter anti-clogging point-shaped water distributor according to one embodiment of the utility model. Figure 6 is based on Figure 5 A magnified schematic diagram of the C region. Figure 1 , Figure 2 , Figure 3 , Figure 5 as well as Figure 6 In the embodiment, the pre-filter anti-clogging point-shaped water distributor may include a water distributor body 1, a filter tube 6 and a filter assembly. Specifically, the filter tube 6 may include a strip hole 4 and a strip plate 5; the filter assembly may include a filter cartridge 15 and a filter screen 12.

[0049] One end of the filter tube 6 is connected to the top pipe of the water distributor body 1, and the other end of the filter tube 6 is used to communicate with the liquid inlet pipe. The strip hole 4 is opened on the side wall of the filter tube 6, and the strip plate 5 is arranged inside the strip hole 4 and is fixed with the strip hole 4. The filter cartridge 15 is rotatably arranged inside the filter tube 6, and the side wall of the filter cartridge 15 is circumferentially provided with water outlet holes, and a column 13 is formed between two adjacent water outlet holes. The filter screen 12 surrounds the outside of the plurality of columns 13, and one end of the filter screen 12 is detachably connected to one of the columns 13, and the other end of the filter screen 12 is connected to the strip plate 5.

[0050] When water enters the liquid inlet pipe, it enters the interior of the filter cartridge 15 along the other end of the filter tube 6, and filters out impurities that may cause the water distributor body 1 to be blocked through the filter screen 12, and finally the water distributor body 1 distributes water. When the filter screen 12 needs to be removed, pull the strip plate 5 so that the strip plate 5 is separated from the strip hole 4. During the movement of the strip plate 5, the filter screen 12 is driven to move synchronously. Since the filter screen 12 surrounds the outside of multiple columns 13, when the filter screen 12 moves, the filter cartridge 15 will follow the auxiliary rotation so that the filter screen 12 can be moved out along the strip hole 4, and finally the connection between one end of the filter screen 12 and one of the columns 13 can be removed. When the filter screen 12 needs to be replaced and installed, one end of the new filter screen 12 is connected to one of the columns 13, and the filter cartridge 15 is rotated to drive the filter screen 12 to surround along the outside of multiple columns 13, and then cooperate with the filter cartridge 15 to form a filtering structure, and finally the strip plate 5 is clamped and fixed in the strip hole 4.

[0051] When a traditional water distributor is used, some impurities will be contained in the incoming water, which will cause blockage in the water distributor when the water distributor works for a long time, affecting the normal operation of the water distributor and reducing the service life of the water distributor. In this embodiment of the utility model, the filter structure composed of the filter screen 12 and the filter cartridge 15 can filter the impurities in the water, prevent the impurities from entering the water distributor body 1 and clogging the water distributor body 1, and ensure the normal operation of the water distributor body 1. At the same time, the strip plate 5 and the filter cartridge 15 are used to replace the filter screen 12, which can realize the convenient replacement of the filter screen 12, reduce the filtering cost, and ensure the filtering effect of the filter tube 6.

[0052] In this embodiment of the present invention, if Figure 1 , Figure 3 as well as Figure 5 As shown, the filter tube 6 may also include a cone tube section 2 and a column tube section 3.

[0053] The bottom end of the cone pipe section 2 is communicated with the top pipe of the water distributor body 1 , and the bottom end of the column pipe section 3 is communicated with the top end of the cone pipe section 2 .

[0054] The column pipe section 3 is used to receive and filter the incoming water. The cone pipe section 2 is a conical pipe, that is, a funnel-shaped pipe, which is used to collect the filtered water so that it can quickly and stably enter the water distributor body 1.

[0055] In this embodiment of the present invention, if Figure 2 as well as Figure 6 As shown, the filter tube 6 may further include a water inlet pipe 7 and a ring plate 9 .

[0056] The water inlet pipe 7 is fixedly arranged at the top of the column pipe section 3 through multiple sets of first connecting plates 8.

The ring plate 9 is arranged between the column pipe section 3 and the water inlet pipe 7. The ring plate 9 is rotatably connected to the column pipe section 3 and the water inlet pipe 7. The ring plate 9 is fixedly connected to the top of the filter cartridge 15 through multiple L-shaped plates 16.

[0057] Considering that the water in the water inlet pipe 7 can stably enter the interior of the filter cartridge 15, the axial diameter of the water inlet pipe 7 is less than or equal to the axial diameter of the filter cartridge 15. Furthermore, one end of the water inlet pipe 7 extends along the top opening of the filter cartridge 15 to the interior of the filter cartridge 15, which can further improve the filtering effect on the incoming water. Since the filter cartridge 15 is fixedly connected to the ring plate 9, when the filter screen 12 is removed, the ring plate 9 will rotate synchronously with the filter cartridge 15. Similarly, when it is necessary to drive the filter cartridge 15 to rotate to install the filter screen 12, just rotate the ring plate 9, which is simple and quick to operate.

[0058] In this embodiment of the present invention, if Figure 2 as well as Figure 6 As shown, considering the convenience of rotating the ring plate 9, a plurality of groups of toggle blocks 10 are provided on the top circumference of the ring plate 9.

Specifically, the stepped shape combined with the vertical arrangement of the filter tube 6 can effectively prevent water from splashing out. Furthermore, a sealing ring is arranged at the step, which effectively improves the sealing strip of the ring plate 9, the water inlet pipe 7 and the column pipe section 3, and can effectively prevent water from overflowing.

[0060] In this embodiment of the utility model, in order to avoid continuous injection of water into the filter cartridge 15, which causes part of the water to enter the water distributor body 1 without being filtered, a flow control valve (not shown in the figure) can be set between the water inlet pipe 7 and the liquid inlet pipe to adjust the amount of water injected.

[0061] In this embodiment of the utility model, the connection between the conical pipe section 2 and the top pipe of the water distributor body 1, the water inlet pipe 7 and the flow control valve, or the water inlet pipe 7 and the liquid inlet pipe includes but is not limited to flange connection. Specifically, considering that some impurities may fall when replacing the filter screen 12, the flange connecting the water distributor body 1 and the conical pipe section 2 can be removed first, and then the filter screen 12 is replaced, and the inside of the filter tube 6 is cleaned.

[0062] In this embodiment of the present invention, if Figure 5 as well as Figure 7 As shown, the filter assembly may further include a circular plate 17 and a circular groove 18 .

[0063] The circular plate 17 is arranged inside the column tube section 3 and close to the bottom end of the column tube section 3. The circular plate 17 is fixedly connected to the inner wall of the column tube section 3 through multiple sets of second connecting plates 19. The circular groove 18 is opened on the top of the circular plate 17. The bottom end of the filter cartridge 15 extends into the circular groove 18 and is rotatably connected to the circular groove 18.

[0064] The circular groove 18 can limit the bottom end of the filter cartridge 15 , and can cooperate with the ring plate 9 to limit the two ends of the filter cartridge 15 , and the filter cartridge 15 can rotate in the column tube section 3 .

[0065] In this embodiment of the present invention, if Figure 3 and Figure 4 As shown, the pre-filter anti-clogging point-shaped water distributor may also include a limiting groove 14, a first magnetic strip and a second magnetic strip.

[0066] A limiting groove 14 is provided on the side wall of one of the pillars 13, and a first magnetic strip is provided on the inner wall of the limiting groove 14. A second magnetic strip (not shown in the figure) that cooperates with the first magnetic strip and is fixed by magnetic attraction is provided at one end of the filter screen 12.

[0067] The method of setting the second magnetic strip at one end of the filter 12 includes but is not limited to setting a long strip plate with the second magnetic strip installed at one end of the filter 12, sewing the first magnetic strip at one end of the filter 12, etc. The method of using the first magnetic strip and the second magnetic strip to cooperate with magnetic fixation is convenient and reliable in disassembly / installation on the one hand, and can be suitable for installing the filter 12 into the filter tube 6 at a smaller opening such as the bar hole 4 on the other hand.

[0068] In this embodiment of the present invention, if Figure 3 as well as Figure 5 As shown, the outer side wall of the strip plate 5 is provided with a pull buckle 11. Specifically, the pull buckle 11 can facilitate pulling the strip plate 5 and replacing the filter screen 12.

[0069] In this embodiment of the present invention, if Figure 4As shown, the joint between the strip plate 5 and the strip hole 4 is in a step shape. Further, a sealing strip is provided at the step, and the shape of the sealing strip is adapted to the edge of the strip plate 5. The step and the sealing strip cooperate to seal between the strip plate 5 and the strip hole 4, effectively preventing the water inside the filter tube 6 from overflowing. In addition, since the strip plate 5 and the strip hole 4 are fixed by clamping, the strip plate 5 can fully squeeze the sealing strip to further improve the sealing effect.

[0070] In this embodiment of the utility model, the clamping structure between the strip hole 4 and the strip plate 5 includes but is not limited to the buckle and slot matching structure known to those skilled in the art. In addition, a cable tie, an elastic rope, etc. may be tied to the outside of the filter tube 6 to allow the strip plate 5 to fully squeeze the sealing strip.

[0071] Through the above technical scheme, the pre-filter anti-blocking point-shaped water distributor provided by the utility model can cooperate with the filter cartridge 15 and the filter screen 12 to filter the impurities in the incoming water, prevent the impurities from entering the water distributor body 1 and blocking the water distributor body 1, and ensure the normal operation of the water distributor body 1. When the filter screen 12 needs to be replaced, pull the strip plate 5 so that the strip plate 5 moves out of the strip hole 4, and the strip plate 5 drives the filter screen 12 to move out with it. At this time, the filter cartridge 15 rotates so that the filter screen 12 gradually moves out of the strip hole 4, and then the other end of the filter screen 12 is disassembled. After the disassembly is completed, one end of the filter screen 12 is connected to one of the columns 13, and the filter cartridge 15 is rotated to drive the filter screen 12 to be wound along the outside of the multiple columns 13 until the strip plate 5 enters the inside of the strip hole 4 and is engaged with the strip hole 4; the use of this structure can realize the convenient replacement of the filter screen 12 to ensure the filtering effect of the filter tube 6.
