Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, and in particular to a filtering device used for water purifiers. Background Art

[0002] A water purifier, also known as a water purifier or water purifier, is a water treatment device that deeply filters and purifies water according to water usage requirements. It is widely used in households and industries. Existing water purifiers mainly purify water through a filter membrane installed inside the filter element. Although this method can remove bacteria, pathogens, toxins, heavy metals and other impurities in the water.

[0003] For example, a Chinese patent with announcement number CN211513690U discloses a filtering device for a water purifier, which relates to the technical field of water purifiers. The utility model includes a filter tank and a three-way water inlet pipe. The filter tank is connected to a purified water outlet pipe on the side surface, and a support is fixedly connected to the bottom of the filter tank; the bottom surface of the filter tank is rotatably connected to an actuator pipe; the top of the filter tank is connected to an upper water inlet branch pipe; the inner wall of the filter tank is rotatably connected to an upper water distribution plate and a lower water distribution plate; a group of water distribution holes are provided on one surface of the upper water distribution plate and the lower water distribution plate; a group of filter cartridges are connected between the opposite surfaces of the upper water distribution plate and the lower water distribution plate through the water distribution holes. The utility model changes the traditional one-way water inlet into a two-way water inlet. By changing the two-way water inlet mode, the problem that the filter element of the traditional filtering mechanism is prone to one-way blockage or high one-way loss is solved. At the same time, the device changes the fixed purification of the traditional filter element into a rotating purification, thereby solving the problem that the filter cartridge close to the purified water outlet pipe is prone to blockage in the traditional mode.

[0004] The existing technology has the following problems:

[0005] When a water purifier purifies water, it usually needs components such as filter elements to filter out impurities in the water. After a certain period of time, the filter element will adsorb a large amount of impurities, resulting in a decrease in adsorption capacity. At this time, the filter element needs to be replaced. However, the filter element in the filtration device is located on the water inlet side on both the upper and lower sides, making it difficult to install and disassemble. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 , Figure 2 and Figure 5 As shown, a filtering device for a water purifier includes a protective shell 1, a water inlet 2 is fixedly connected to the upper surface of the protective shell 1 near the left side, a drain pipe 3 is fixedly connected to the lower surface of the protective shell 1 near the bottom axis, a partition mechanism 5 is fixedly connected to the inner side of the protective shell 1, a filter cartridge body 4 is movably sleeved on the inner side of the partition mechanism 5, and a fixing mechanism 6 is fixedly connected to the upper side of the partition mechanism 5.

[0027] It should be noted that the filter cartridge body 4 is used to filter impurities in water, and the filter cartridge body 4 is cylindrical.

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, the separation mechanism 5 includes an outer isolation cylinder 51, the lower surface of which is fixedly connected to the middle of the inner lower surface of the protective shell 1, and an inner isolation cylinder 52 is fixedly connected to the middle of the inner lower surface of the protective shell 1, and the inner isolation cylinder 52 is located on the inner side of the outer isolation cylinder 51, and the inner and outer sides of the filter cartridge body 4 are movably sleeved between the outer isolation cylinder 51 and the inner isolation cylinder 52.

[0029] It should be noted that holes for water pipes are provided on the outer isolation cylinder 51 and the inner isolation cylinder 52. The outer isolation cylinder 51 and the inner isolation cylinder 52 are used to fix the filter cylinder body 4. Water enters the filter cylinder body 4 from the outside of the outer isolation cylinder 51, and then the filtered water enters the inside of the inner isolation cylinder 52.

[0030] like Figure 2 , Figure 3 As shown, a water storage cylinder 53 is fixedly connected to the inner lower surface of the protective shell 1 near the edge, and the outer isolation cylinder 51 is located on the inner side of the water storage cylinder 53, and a plurality of evenly distributed partitions 54 are fixedly connected to the inner side of the water storage cylinder 53 to avoid being fixedly connected to the outer side of the water storage cylinder 53, and a diverter 55 is fixedly connected to the inner upper surface of the protective shell 1 near the edge, and a cavity formed by a plurality of adjacent partitions 54 is fixedly connected to the lower side of the diverter 55, and the upper side of the diverter 55 is connected to the water inlet 2.

[0031] It should be noted that the water storage cylinder 53 is used to store water to be filtered, and the partition 54 is used to divide the space inside the entire water storage cylinder 53, so that the water pressure in various parts of the whole is roughly consistent, and the filtration efficiency of various parts of the filter cartridge body 4 is roughly consistent, so as to avoid the problem that the water pressure on the lower side is too high, resulting in saturation of impurities absorption on the lower side while the upper side can still absorb impurities, resulting in the water on the lower side being difficult to filter before replacing the new filter cartridge body 4.

[0032] like Figure 4 , Figure 5 As shown, the fixing mechanism 6 includes a connecting seat 61, the lower surface of the connecting seat 61 is fixedly connected to the upper side of the filter cartridge body 4, the outer wall of the connecting seat 61 is movably sleeved in a circular hole opened in the middle of the upper wall of the protective shell 1, the outer wall of the connecting seat 61 is movably sleeved with a rotating seat 62, a spring 63 is fixedly connected at the inner axis of the connecting seat 61, and the spring 63 is located on the inner side of the rotating seat 62, and the front and rear sides of the rotating seat 62 are fixedly connected with limiting plates 64, and a limiting groove 65 is opened on the upper surface of the protective shell 1 near the front and rear sides of the circular hole, and the outer wall of the limiting plate 64 is movably sleeved on the inner side of the limiting groove 65.

[0033] It should be noted that when the limiting plate 64 is movably sleeved on the inner side of the limiting groove 65, the rotating seat 62 cannot rotate, and the spring 63 presses the rotating seat 62 and the filter cartridge body 4 up and down, so that the filter cartridge body 4 is fixed.

[0034] like Figure 4 As shown, through grooves 66 are provided on the left and right sides of the inner side of the circular hole on the upper wall of the protective shell 1 .

[0035] It should be noted that the rotating seat 62 is pressed downward to cause the limiting plate 64 to disengage from the limiting groove 65, and then the rotating seat 62 is rotated so that the limiting plate 64 is aligned with the through groove 66, so that the filter cartridge body 4 and the fixing mechanism 6 can be pulled upward as a whole.

[0036] like Figure 5 As shown, a rubber pad 67 is fixedly connected to the lower surface of the filter cartridge body 4 .

[0037] It should be noted that, because the spring 63 presses the filter cartridge body 4 downward, the rubber pad 67 closes the gap between the filter cartridge body 4 and the lower surface of the protective shell 1, preventing a small amount of unfiltered water from directly entering the inner side of the inner isolation cylinder 52 from here.

[0038] like Figure 1 As shown, four annularly distributed supporting feet are fixedly connected to the lower surface of the protective shell 1.

[0039] It should be noted that the support legs are used to prop up the protective shell 1 so that the drain pipe 3 is suspended in the air to prevent the drain pipe 3 from contacting the bottom surface. At the same time, rubber sheets are contained thereon to reduce the overall shaking caused by external or internal vibrations.

[0040] like Figure 1 As shown, a valve mechanism is movably installed on the outer wall of the drain pipe 3 near the right end.

[0041] It should be noted that the valve mechanism is used to control the opening and closing of the drain pipe 3 to control whether the drain pipe 3 releases the filtered water.

[0042] The working principle of the utility model is as follows: first, when the limiting plate 64 is movably sleeved on the inner side of the limiting groove 65, the rotating seat 62 cannot rotate, and the spring 63 presses the rotating seat 62 and the filter cartridge body 4 up and down, so that the filter cartridge body 4 is fixed, and the rotating seat 62 is pressed downward, so that the limiting plate 64 is disengaged from the limiting groove 65, and then the rotating seat 62 is rotated so that the limiting plate 64 is aligned with the through groove 66, so that the filter cartridge body 4 and the fixing mechanism 6 can be pulled out upward as a whole, and the limiting plate 64 is moved to under the upper wall of the protective shell 1 through the through groove 66, and is fixed with the limiting groove 65, so that the filter cartridge body 4 is installed in place, which is convenient for disassembly, installation and operation, and facilitates the subsequent maintenance operation of the filtering device. Finally, the outer isolation cylinder 51 and the inner isolation cylinder 52 are provided with holes for water pipes to pass through. The outer isolation cylinder 51 and the inner isolation cylinder 52 are used to fix the filter cartridge body 4, and water is drawn from the outside. The outer side of the isolation cylinder 51 enters the filter cartridge body 4, and then the filtered water enters the inner side of the inner isolation cylinder 52. The water storage cylinder 53 is used to store the water to be filtered, and the partition 54 is used to separate the space inside the entire water storage cylinder 53, so that the water pressure in various parts of the whole are roughly the same, so that the filtration efficiency of various parts of the filter cartridge body 4 is roughly the same, and it is avoided that the water pressure on the lower side is too high, resulting in saturation absorption of impurities on the lower side, while the upper side can still absorb impurities, resulting in the problem that the water on the lower side is difficult to filter before replacing the new filter cartridge body 4. The water passes through the outer isolation cylinder 51 from the side, so that it enters the filter cartridge body 4 from the side during filtration, so that the overall contact area is increased, and the filtration speed is accelerated. At the same time, due to filtering from the side, the problem of water entering from the upper and lower sides, which causes blockage of the filter cartridge body 4 on one side, is avoided, so that the filter cartridge body 4 as a whole can be fully utilized, avoiding waste and increasing costs.

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
