Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a water purifier, and more particularly to a small water purifier. Background Technology

[0002] A water purifier is a household appliance used to purify water sources. It effectively removes pollutants and harmful components from water using technologies such as activated carbon adsorption, ultrafiltration, and reverse osmosis to provide cleaner water.

[0003] However, water purifiers based on this technology have drawbacks such as low purification efficiency and large size. Utility Model Content

[0004] In view of this, the present invention provides a water purifier that has high purification efficiency and small size.

[0005] This utility model provides a water purifier, comprising: a purification section having a receiving cavity filled with a first filter material; a first water distributor having an inlet for allowing water to enter and a first water distribution plate for allowing water to pass through, the first water distribution plate extending at least partially into the first filter material; and a water purification channel through which water purified by the first filter material flows out.

[0006] Optionally, the first water distribution plate is formed as the sidewall and / or bottom plate of the first water distributor.

[0007] Optionally, the water purifier further includes: a conversion device, an inlet pipe, a purification pipe, and a drain pipe disposed outside the receiving cavity; the conversion device is configured to connect or isolate the purification channel, the inlet, the inlet pipe, the drain pipe, and the purification pipe.

[0008] Optionally, the conversion device is further configured to connect the water inlet to the water inlet pipe and the purified water channel to the purification pipe, so that the water purifier enters the filtration mode.

[0009] Optionally, the conversion device is further configured to connect the purified water channel to the inlet pipe and the inlet to the drain pipe, so that the water purifier enters the backwashing mode.

[0010] Optionally, the conversion device is further configured to connect the water inlet to the water inlet pipe and the purified water channel to the drain pipe, so that the water purifier enters the positive flushing mode.

[0011] Optionally, the water purifier includes a second water distributor disposed within the first filter media and communicating with the water purification channel, wherein the second water distributor forms a second water distribution plate that allows water to pass through.

[0012] Optionally, the first water distribution plate and / or the second water distribution plate are formed with a plurality of filter holes that allow water to pass through.

[0013] Optionally, the purified water channel passes through the first water distributor.

[0014] Optionally, the first water distributor is filled with a second filter media.

[0015] According to this embodiment of the invention, since at least a portion of the water flows directly from the first water-dividing plate into the first filter media, rather than gradually entering the first filter media through its surface, it can drive some of the first filter media to move within the first filter media. This prevents impurities in the water from accumulating on the surface of the first filter media, thus ensuring the purification efficiency of the water purifier. Furthermore, because some of the first filter media moves while the other portion remains stationary, the stationary portion can filter and purify water through the gaps between the filter media, while the moving portion can enhance adsorption by increasing the contact area between the water and the filter media. This allows the first filter media within the cavity to both filter impurities and increase its adsorption capacity, thereby improving the purification efficiency of the water purifier. Moreover, since the first water-dividing plate extends at least partially into the first filter media, it improves the integration of the water purifier, thereby reducing its size and achieving miniaturization.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The orientations or positional relationships described below are for the convenience of describing this utility model and simplifying the description only, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model. Specifically, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In the process of developing this utility model, it was discovered that because the water distributor in the water purifier is located above the filter media, water flows out from the distributor and gradually enters the filter media from its surface. Impurities in the water accumulate on the surface of the filter media, thus reducing the purification efficiency of the water distributor. Therefore, this utility model provides a water purifier.

Figure 2 This is a cross-sectional view of a water purifier according to an illustrative embodiment of the present invention. Figure 3 This is a perspective view of a water purifier according to an illustrative embodiment of the present invention after the outer casing has been removed. Figure 4 This is an exploded view of the first water distributor 2 according to an illustrative embodiment of the present invention. Figure 5 This is a schematic diagram of the filtration principle of a water purifier according to an embodiment of the present invention.

[0034] Reference Figures 1-5 As shown, the water purifier in this embodiment can be a central water purifier, which can effectively remove chlorine, rust, heavy metals, viruses, algae, and suspended solids from the water. The water purifier can include a purification section 1, a first water distributor 2, and a purification channel 3. The purification section 1 can form a receiving cavity 11. The receiving cavity 11 can be filled with first filter media 12. The first water distributor 2 can form a first water dividing plate 21 and a water inlet 22. The water inlet 22 can allow water to enter. The first water dividing plate 21 can extend at least partially into the first filter media 12. At least part of the water can flow directly from the first water dividing plate 21 into the first filter media 12 to drive part of the first filter media 12 to move. The purification channel 3 can extend from the bottom of the first water distributor 2 out of the purification section 1. The water purified by the first filter media 12 can flow out from the purification channel 3. A filter screen can be provided at the bottom of the purification channel 3, which can prevent the first filter media 12 from entering the purification channel 3 from the bottom of the purification channel 3.

[0035] In some illustrative embodiments, the purification unit 1 may be configured as a barrel-shaped structure. For example... Figure 2 As shown, the purification unit 1 may have an opening 13 for connecting with other accessories.

[0036] In some illustrative embodiments, the first filter material 12 may include, but is not limited to, activated carbon. For example, the first filter material 12 may be any material with water purification function, such as quartz sand, zeolite, and clay minerals.

[0037] In some illustrative embodiments, the first water distributor 2 can be used to divert the water within it to expand the water flow area. Further, the water requiring purification can flow into the first water distributor 2 through the inlet 22, and after being diverted by the first water distribution plate 21, flow into the first filter media 12, where it is purified. The water requiring purification can be tap water, water filtered by a pre-filter, or any other type of water requiring purification.

[0038] According to this embodiment of the invention, since at least a portion of the water flows directly from the first water distribution plate 21 into the first filter media 12, rather than gradually entering the first filter media 12 through its surface, it can drive a portion of the first filter media 12 (e.g., the upper portion) to move within the first filter media 12. This prevents impurities in the water from accumulating on the surface of the first filter media 12, thus ensuring the purification efficiency of the water purifier. Furthermore, since a portion of the first filter media 12 moves while another portion remains stationary, the stationary portion can filter and purify the water through the gaps between the first filter media 12, while the moving portion can enhance the adsorption effect by increasing the contact area between the water and the first filter media 12. This allows the first filter media 12 within the receiving cavity 11 to both filter impurities in the water and increase its adsorption capacity, thereby improving the purification efficiency of the water purifier. Furthermore, since the first water distribution plate 21 extends at least partially into the first filter media 12, the integration of the water purifier can be improved, thereby reducing the size of the water purifier and achieving miniaturization of the water purifier.

[0039] Reference Figures 4-5 As shown, in some illustrative embodiments, the first water-dividing plate 21 can be formed as the sidewall of the first water distributor 2, wherein the arrow direction can indicate the water flow direction. Water can flow into the first filter media 12 from the sidewall of the first water distributor 2. The first water-dividing plate 21 can be configured as an annular conical structure. It should be understood that the embodiments of this utility model are not limited thereto. For example, the first water-dividing plate 21 can be configured as a rectangular, square, pentagonal, heptagonal, octagonal, or other plate-like structure.

[0040] Figure 6 This is a schematic diagram of the filtration principle of a water purifier according to another illustrative embodiment of the present invention.

[0041] Reference Figure 6As shown, in some illustrative embodiments, the first water-dividing plate 21 can be formed as the base plate of the first water distributor 2. Water can flow into the first filter media 12 from the base plate of the first water distributor 2. The first water-dividing plate 21 can be configured as a circular structure. The first water-dividing plate 21 is entirely located within the first filter media 12, meaning that the water in the first water distributor 2 flows directly into the first filter media after exiting the first water-dividing plate 21. It should be understood that the embodiments of this utility model are not limited thereto. For example, the first water-dividing plate 21 can be configured as a rectangular, square, pentagonal, heptagonal, octagonal, or other plate-shaped structure.

[0042] Reference Figure 4 As shown, in some illustrative embodiments, the first water distribution plate 21 may have a plurality of filter holes 6 that allow water to pass through. Water in the first water distributor 2 can enter the receiving cavity 11 through the filter holes 6 of the first water distribution plate 21, or water in the receiving cavity 11 can enter the first water distributor 2 through the filter holes 6 of the first water distribution plate 21.

[0043] Reference Figure 2 As shown, in some illustrative embodiments, the water purifier may further include a conversion device 4, an inlet pipe 7, a drain pipe 8, and a purification pipe 9. The conversion device 4 may be connected to the purified water channel 3, the inlet 22, the inlet pipe 7, the drain pipe 8, and the purification pipe 9, respectively. The conversion device 4 is configured to connect or isolate the purified water channel 3, the inlet 22, the inlet pipe 7, the drain pipe 8, and the purification pipe 9.

[0044] Furthermore, the switching device 4 can be a device capable of changing the flow path of a fluid or medium, enabling it to switch between multiple pipes. The switching device 4 can include, but is not limited to, switching valves and control valves. The inlet pipe 7 can be connected to an external water supply device. The external water supply device can provide water for preliminary filtration by the water purifier, such as a pre-filter, which can pre-filter impurities in the water.

[0045] Reference Figure 2 As shown, in some illustrative embodiments, the water purifier may also include a control device 10. The control device 10 may be used to control the switching device 4 to connect or isolate the water purification channel 3, the water inlet 22, the water inlet pipe 7, the drain pipe 8, and the purification pipe 9.

[0046] The conversion device 4 may be equipped with a gear transmission structure. After receiving a signal from the control device 10, the conversion device 4 can connect or isolate the water purification channel 3, the water inlet 22, the water inlet pipe 7, the drainage pipe 8, and the purification pipe 9 based on the gear transmission structure.

[0047] Reference Figures 1-2 As shown, in some illustrative embodiments, the water purifier may also include a housing 14. The housing 14 may have a display screen panel for interacting with the control device 10.

[0048] In some illustrative embodiments, the conversion device 4 can also be used to connect the water inlet 22 to the water inlet pipe 7 and the purified water channel 3 to the purification pipe 9, so that the water purifier enters the filtration mode.

[0049] Reference Figure 5 and Figure 6 As shown, in filtration mode, water to be purified flows from the inlet pipe 7 through the inlet 22 into the first water distributor 2. At least a portion of the water flows directly from the filter holes 6 into the first filter media 12, causing some of the first filter media 12 to move. This increases the contact area between the water and the first filter media 12, thereby improving the adsorption rate of the first filter media 12 for impurities in the water. After passing through the moving first filter media 12, the water flows to the stationary first filter media 12. Some impurities in the water are adsorbed by the moving first filter media 12, while some impurities are filtered by the stationary first filter media 12, resulting in high purification efficiency. The water purified by the first filter media 12 flows out of the water purifier through the purification channel 3 and the purification pipe 9. The purification pipe 9 may include, but is not limited to, connecting to water-using appliances such as faucets and heaters.

[0050] Figure 7 This is a schematic diagram illustrating the backwashing principle of a water purifier according to an embodiment of the present invention.

[0051] In some illustrative embodiments, the conversion device 4 can also be used to connect the water purification channel 3 to the water inlet pipe 7 and the water inlet 22 to the drain pipe 8, so that the water purifier enters the backwashing mode.

[0052] Reference Figure 7 As shown, in the backwash mode, water can enter the receiving chamber 11 from the inlet pipe 7 via the clean water channel 3, then enter the first water distributor 2 from the receiving chamber 11, and then flow out of the water purifier from the first water distributor 2 through the drain pipe 8.

[0053] Figure 8 This is a schematic diagram of the forward flushing principle of a water purifier according to an embodiment of the present invention.

[0054] In some illustrative embodiments, the conversion device 4 is also configured to connect the inlet 22 to the inlet pipe 7 and the purified water channel 3 to the drain pipe 8, so that the water purifier enters the positive flushing mode.

[0055] Reference Figure 8 As shown, in the positive flushing mode, water can enter the first water distributor from the inlet 22 of the water inlet pipe 7, enter the receiving chamber 11 from the first water distributor, then enter the clean water channel 3 from the receiving chamber 11, and then flow out of the water purifier from the clean water channel 3 through the drain pipe 8.

[0056] Figure 9This is a perspective view of a second water distributor according to an illustrative embodiment of the present utility model. Figure 10 This is a perspective view of a first water distributor and a second water distributor according to an illustrative embodiment of the present utility model.

[0057] In some illustrative embodiments, the water purifier may further include a second water distributor 5. The second water distributor 5 may be disposed within the first filter media 12 and communicate with the water purification channel 3, and the second water distributor 5 forms a second water distribution plate 51 that allows water to pass through.

[0058] Reference Figure 9 As shown, in some illustrative embodiments, the second water distributor 5 may have a second opening 53 communicating with the water purification channel 3.

[0059] Reference Figure 9 As shown, the second water distribution plate 51 can be formed with multiple filter holes 6 that allow water to pass through. Water in the receiving cavity 11 can enter the clean water channel 3 through the filter holes 6 of the second water distribution plate 51, or water in the clean water channel 3 can enter the receiving cavity 11 through the filter holes 6 of the second water distribution plate 51.

[0060] Reference Figure 5 and Figure 6 As shown, in filtration mode, the water purified by the first filter media 12 can enter the second water distributor 5 through the receiving cavity 11, and then flow from the second water distributor 5 to the clean water channel 3.

[0061] Reference Figure 7 As shown, in backwash mode, water can enter the second water distributor 5 through the clean water channel 3, and then flow into the receiving cavity 11 through the second water distributor 5.

[0062] Reference Figure 8 As shown, in backwash mode, water can enter the second water distributor 5 from the receiving cavity 11, and then flow into the clean water channel 3 from the second water distributor 5.

[0063] In some illustrative embodiments, the particle size of the first filter media 12 is larger than the diameter of the filter holes 6 of the second water distribution plate 51, so as to ensure that the first filter media 12 cannot enter the second water distributor 5 through the filter holes 6 of the first water distribution plate 21.

[0064] Reference Figure 10 As shown, in some illustrative embodiments, the water purification channel 3 passes through the first water distributor 2, meaning the first water distributor 2 can be fitted onto the water purification channel 3, thereby improving the integration of the water purifier. For example, the first water distributor 2 and the water purification channel 3 can be coaxially arranged.

[0065] In some illustrative embodiments, the first water distributor 2 is filled with a second filter media 52. The second filter media 52 may include, but is not limited to, KDF filter media. For example, the second filter media 52 may be any material with water purification function, such as quartz sand, zeolite, activated carbon, and clay minerals. Further, the second filter media 52 may be an alloy filter media, and the first filter media 12 may be a filter media with adsorption function.

[0066] Furthermore, the first water distributor 2 may have a first opening 23. The purified water channel 3 can extend into the first water distributor 2 through the first opening 23 and exit into the first filter media 12. A storage cavity 24 for accommodating the second filter media 52 can be formed between the purified water channel 3 and the first water distribution plate 21. The particle size of the second filter media 52 may be larger than the diameter of the filter holes 6 of the first water distribution plate 21 to ensure that the second filter media 52 cannot flow out of the filter holes 6 of the first water distribution plate 21.

[0067] The above describes the structure; the following describes the working process of the water purifier.

[0068] When purified water is needed, the control device 10 controls the switching device 4 to put the water purifier into filtration mode. Specifically, the water inlet 22 is connected to the water inlet pipe 7, and the purified water channel 3 is connected to the purification pipe 9.

[0069] Water enters the first water distributor 2 through inlet 22, is filtered by the second filter media, and then flows through the filter holes 6 of the first water distribution plate 21 into the receiving cavity 11 to contact the first filter media 12. The first water distribution plate 21 extends at least partially into the first filter media 12, so at least a portion of the water filtered by the first water distributor 2 directly reaches the interior of the first filter media 12. Due to the impact force of the water directly reaching the interior of the first filter media 12, the first filter media 12 is lifted, increasing the contact area between the water and the first filter media 12, thereby improving the adsorption rate of the first filter media 12. The water purified by the lifted first filter media 12 is then filtered again by the unlifted first filter media 12. After being purified by the first filter media 12, the water enters the second water distributor 5 through the filter holes 6 of the second water distribution plate 51, and then flows through the purified water channel 3 into the purified pipe 9.

[0070] When backwashing is required, the control device 10 controls the switching device 4 to put the water purifier into backwashing mode. Specifically, the water purification channel 3 is connected to the water inlet pipe 7, the water inlet 22 is connected to the drain pipe 8, and the water inlet 22 is isolated from the water inlet pipe 7. Water enters from the water purification channel 3 and reaches the second water distributor 5, then enters the first filter media 12 from the second water distributor 5. After passing through the first filter media 12, it enters the first water distributor 2 from the filter holes 6, and after passing through the second filter media 52, it is discharged from the drain pipe 8.

[0071] When forward flushing is required, the control device 10 controls the switching device 4 to put the water purifier into forward flushing mode. Specifically, the inlet 22 is connected to the inlet pipe 7, the purified water channel 3 is connected to the drain pipe 8, and the purified water channel 3 is isolated from the purification pipe 9. After water enters through the inlet 22, it first enters the first water distributor 2. After being filtered by the second filter media, the water is discharged from the filter holes 6 of the first water distributor 2 into the receiving cavity 11, where it comes into contact with the first filter media 12. The water filtered by the first filter media 12 enters the second water distributor 5 through the filter holes 6, and then flows into the drain pipe 8 through the purified water channel 3.
