Technical Field

[0001] This utility model relates to the field of filter technology, and more specifically, to a kitchen water pre-filter. Background Technology

[0002] A pre-filter is the first coarse filtration device for the whole house's water supply. It can filter out large particles such as sediment, rust, insect eggs, and red worms from tap water. It is usually installed under the kitchen sink. However, after the existing pre-filter is installed, when there are too many impurities in the water, the water pressure can easily decrease, which will affect normal use. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a kitchen water pre-filter, which has the advantage of not changing the water pressure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a kitchen water pre-filter, including a connector, a mating interface fixedly installed at the bottom of the connector, a filter tube engaged at the bottom of the mating interface, a connecting pipe inserted into the bottom of the filter tube, a dispersing pipe fixedly installed at the end of the connecting pipe away from the filter tube, an outlet pipe fixedly installed on the right side of the connector, an inlet pipe fixedly installed on the left side of the connector, a control valve rotatably connected inside the inlet pipe, a sliding groove first opened inside the mating interface, a slider first slidably connected inside the sliding groove first, and a filter plate fixedly installed at the end of the slider first away from the sliding groove first.

[0005] As a preferred embodiment of this utility model, there are three filter plates arranged vertically. A first filter sponge is fixedly installed above the uppermost filter plate, a second filter sponge is fixedly installed above the middle filter plate, and a third filter sponge is fixedly installed above the lowermost filter plate. A connecting shaft is fixedly installed inside each filter plate, and the connecting shaft is coaxial with each of the three filter plates.

[0006] As a preferred embodiment of this utility model, a connecting sleeve is rotatably connected to the outer side of the connecting shaft, a spiral blade is fixedly installed on the outer side of the connecting sleeve, and a stirring plate is fixedly installed on the outer side of the spiral blade.

[0007] As a preferred embodiment of this utility model, each of the three filter plates has a filter hole inside, and there are multiple filter holes, which are located inside the three filter plates respectively.

[0008] As a preferred embodiment of this utility model, a limiting ring is fixedly installed on the outer side of the connecting shaft. The limiting ring is located above the third filter sponge and is circular in shape. The limiting ring is located below the second filter sponge.

[0009] As a preferred technical solution of this utility model, the inside of the dispersion tube is provided with a second sliding groove, and a second slider is slidably connected inside the second sliding groove. A connecting rod is fixedly installed on the first side of the second slider near the center point of the dispersion tube. A rotating shaft is rotatably connected inside the connecting rod. A second spiral blade is fixedly installed on the outside of the rotating shaft. The diameter of the second spiral blade is smaller than the internal diameter of the dispersion tube.

[0010] As a preferred embodiment of this utility model, a partition is fixedly installed inside the connector. The partition is located in the middle of the filter tube and the dispersion tube. There are two mating interfaces, which are located on the left and right sides of the partition, respectively, and the two mating interfaces engage with the filter tube and the dispersion tube, respectively.

[0011] As a preferred technical solution of this utility model, there are two slide grooves, which are respectively located on the left and right sides of the three filter plates. There are six sliders, which are fixedly connected to the three filter plates and slidably connected to the two slide grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model involves fixing a first filter sponge, a second filter sponge, and a third filter sponge above three filter plates, with the first and second filter sponges each being half of the third filter sponge. The first filter sponge is positioned above the second filter sponge, and the second filter sponge is positioned above the third filter sponge. When water flows through the filter tube, it enters above the interface, where it is filtered by the first filter sponge and the top filter plate. When there are many impurities, the water flows through the other half of the filter plate into the area above the second filter sponge, where it continues to be filtered by the second filter sponge and the filter plate at the bottom of the second filter sponge. Finally, the filtered water enters the area above the third filter sponge and is filtered by the third filter sponge. The water flowing above the third filter sponge contains more impurities filtered by the first and second filter sponges. The third filter sponge filters out some small impurities, and the amount of impurities accumulating on top of the third filter sponge is reduced, thus preventing the water flow from being too weak due to excessive impurities.

[0014] 2. This utility model features a sliding groove inside the filter tube, with a slider connected slidably inside the groove. The slider is fixedly installed on the filter plate. When a large amount of debris accumulates on top of the first, second, or third filter sponge, the control valve is rotated to close the inlet pipe. The filter tube is then disassembled from the interface, and the connecting shaft is pulled upwards. This allows the filter plate to be disassembled through the sliding action of the slider and the groove, thus achieving the effect of timely replacement and cleaning of the first, second, and third filter sponges.

[0021] 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.

[0022] like Figures 1 to 5As shown, this utility model provides a kitchen water pre-filter, including a connector 1, a mating interface 2 fixedly installed at the bottom of the connector 1, a filter tube 3 engaged at the bottom of the mating interface 2, a connecting pipe 4 inserted into the bottom of the filter tube 3, a dispersing pipe 5 fixedly installed at the end of the connecting pipe 4 away from the filter tube 3, a water outlet pipe 6 fixedly installed on the right side of the connector 1, a water inlet pipe 7 fixedly installed on the left side of the connector 1, a control valve 8 rotatably connected inside the water inlet pipe 7, a sliding groove 9 opened inside the mating interface 2, a slider 10 slidably connected inside the sliding groove 9, and a filter plate 11 fixedly installed at the end of the slider 10 away from the sliding groove 9.

[0023] The main function of the control valve 8 is to control the water flow. It can close the inside of the inlet pipe 7, so as to prevent water from flowing out when the interface 2 and filter pipe 3 need to be replaced. At the same time, it can control the water flow in time. The main function of the outlet pipe 6 is to discharge the filtered water through the faucet above in time, so as to clean the items in time.

[0024] There are three filter plates 11, which are arranged vertically. The top filter plate 11 has a first filter sponge 12 fixedly installed on top of it, the middle filter plate 11 has a second filter sponge 13 fixedly installed on top of it, and the bottom filter plate 11 has a third filter sponge 14 fixedly installed on top of it. A connecting shaft 15 is fixedly installed inside the filter plate 11, and the connecting shaft 15 is coaxial with the three filter plates 11 respectively.

[0025] The first filter sponge 12 and the second filter sponge 13 are respectively the third filter sponge 14 and are staggered. The first filter sponge 12 is located to the upper left of the second filter sponge 13. Its main function is to divert the flow, achieve partial filtration, ensure normal water pressure, and prevent excessive impurities in the water from clogging the water and causing the water pressure to decrease.

[0026] The connecting shaft 15 is rotatably connected to the outer side of the connecting sleeve 16, the connecting sleeve 16 is fixedly mounted with a spiral blade 17, and the spiral blade 17 is fixedly mounted with a stirring plate 18.

[0027] When water flows from the inside of the inlet pipe 7 into the inside of the connector 1, and then flows into the inside of the filter pipe 3 through the interface 2, the water flow will drive the spiral blade 17 to rotate. At the same time, the stirring plate 18 will rotate with the spiral blade 17, which can give the water flow a certain buffering effect. This will allow the debris accumulated on the three filter plates 11 to rotate, thereby preventing the three filter plates 11 and the first filter sponge 12 from becoming clogged.

[0028] Each of the three filter plates 11 has a filter hole 19 inside. There are multiple filter holes 19, and the multiple filter holes 19 are located inside the three filter plates 11 respectively.

[0029] The main function of the multiple filter holes 19 is to filter out impurities in the water flow and prevent impurities from flowing out with the water flow, thereby ensuring the health of drinking water.

[0030] Among them, a limiting ring 20 is fixedly installed on the outer side of the connecting shaft 15. The limiting ring 20 is located above the third filter sponge 14 and is circular in shape. The limiting ring 20 is located below the second filter sponge 13.

[0031] The main function of the limiting ring 20 is to limit the third filter sponge 14 to prevent it from folding or shifting during the water flow.

[0032] The dispersion tube 5 has a sliding groove 21 inside, and a slider 22 is slidably connected inside the sliding groove 21. A connecting rod 23 is fixedly installed on the first side of the slider 22 near the center point of the dispersion tube 5. A rotating shaft 24 is rotatably connected inside the connecting rod 23. A spiral blade 25 is fixedly installed on the outside of the rotating shaft 24. The diameter of the spiral blade 25 is smaller than the internal diameter of the dispersion tube 5.

[0033] After the filtered water flows into the dispersing pipe 5 through the connecting pipe 4, the water flow will drive the spiral blade 25 to rotate, thereby controlling the flow rate of the water and preventing the water from flowing out inconsistencies.

[0034] The connector 1 has a partition 26 fixedly installed inside. The partition 26 is located in the middle of the filter tube 3 and the dispersion tube 5. There are two interfaces 2, which are located on the left and right sides of the partition 26 respectively. The two interfaces 2 are engaged with the filter tube 3 and the dispersion tube 5 respectively.

[0035] The main function of the partition 26 is to divide the internal space of the connector 1 into two parts, so as to facilitate the filtration of water flow and its transportation out from the other side, thereby achieving the effect of easy filtration.

[0036] There are two slide grooves 9, which are located on the left and right sides of the three filter plates 11 respectively. There are six sliders 10, which are fixedly connected to the three filter plates 11 respectively, and are slidably connected to the two slide grooves 9 respectively.

[0037] When there are many impurities inside the filter tube 3, first remove the filter tube 3 from the inside of the interface 2. Then, take the connecting shaft 15 out upwards. At this time, the filter plate 11 is removed by sliding through the six sliders 10 and the two sliding grooves 9, thereby achieving the effect of easy disassembly and installation.

[0038] Working principle and usage process of this utility model:

[0039] First, a water inlet pipe 7 is fixedly installed on the left side of connector 1. A control valve 8 is rotatably connected inside the water inlet pipe 7. The rotating plate can open and close the inside of the water inlet pipe 7 to facilitate the opening and closing of the water flow.

[0040] Secondly, a first filter sponge 12, a second filter sponge 13, and a third filter sponge 14 are fixedly installed on top of the three filter plates 11, respectively. The first filter sponge 12 and the second filter sponge 13 are each half of the third filter sponge 14. The first filter sponge 12 is located above the second filter sponge 13, and the second filter sponge 13 is located above the third filter sponge 14. When the water flows through the filter pipe 3, it enters above the interface 2. At this time, the first filter sponge 12 and the top filter plate 11 filter the water. When there are many impurities, the water flows through the other half of the filter plate 11 and enters above the second filter sponge 13, where it continues to be filtered by the second filter sponge 13 and the filter plate 11 at the bottom of the second filter sponge 13. Finally, the filtered water enters above the third filter sponge 14 and is filtered by the third filter sponge 14. The impurities in the water flowing above the third filter sponge 14 are mostly filtered by the first filter sponge 12 and the second filter sponge 13. At this time, the third filter sponge 14 filters some small impurities, and the impurities accumulated on the third filter sponge 14 are reduced.

[0041] Meanwhile, a groove 9 is provided inside the filter tube 3, and a slider 10 is slidably connected inside the groove 9. The slider 10 is fixedly installed with the filter plate 11. When there is a lot of debris accumulated on the top of the first filter sponge 12, the second filter sponge 13, or the third filter sponge 14, the control valve 8 is rotated to close the water inlet pipe 7. At this time, the filter tube 3 is disassembled from the inside of the interface 2, and the connecting shaft 15 is pulled upwards, so that the filter plate 11 is disassembled by the sliding action of the slider 10 and the groove 9. This achieves the effect of timely replacement and cleaning of the first filter sponge 12, the second filter sponge 13, and the third filter sponge 14.

[0042] Finally, a sliding groove 21 is provided inside the dispersion tube 5, and a slider 22 is slidably connected inside the sliding groove 21. A connecting rod 23 is fixedly installed on the first side of the slider 22 near the center point of the dispersion tube 5. A rotating shaft 24 is rotatably connected inside the connecting rod 23, and a spiral blade 25 is fixedly installed on the outside of the rotating shaft 24. The diameter of the spiral blade 25 is smaller than the internal diameter of the dispersion tube 5. When the filtered water flows into the dispersion tube 5 through the connecting pipe 4, the water flow will drive the spiral blade 25 to rotate, thereby controlling the flow rate of the water and preventing the water from flowing out inconsistencies.
