[0022] Reference Figure 1 As shown, the water purification structure provided in the embodiment of this utility model includes a filter cartridge 100 and a diverter 500. The filter cartridge 100 has a first flow channel 200, a second flow channel 300, and a third flow channel 400. The second flow channel 300 is provided with a softening resin layer 310, and the third flow channel 400 is provided with an activated carbon layer 410. The filter cartridge 100 has a raw water inlet 110 and a pure water outlet 120. The first inlet 210 of the first flow channel 200 and the second inlet 320 of the second flow channel 300 are both connected to the raw water inlet 110, and the third outlet 420 of the third flow channel 400 is connected to the pure water outlet 120. The diverter 500 is movably disposed on the filter cartridge 100 and moves between a first position and a second position. Figure 2 As shown, in the first position, the third inlet 430 of the third flow channel 400 is connected to the first outlet 220 of the first flow channel 200, and the diverter 500 closes the second outlet 330 of the second flow channel 300; as Figure 1 As shown, in the second position, the third inlet 430 is connected to the second outlet 330, and the diverter 500 closes the first outlet 220.

[0023] By configuring a first flow channel 200, a second flow channel 300, a third flow channel 400, and a diversion component 500, the user can drive the diversion component 500 to move according to the water quality. When the water quality is good, the diversion component 500 connects the first flow channel 200 and the third flow channel 400, and the raw water is filtered only through the activated carbon layer 410. When the water quality is poor, the diversion component 500 connects the second flow channel 300 and the third flow channel 400, and the raw water is filtered sequentially through the softening resin layer 310 and the activated carbon layer 410. This allows different filtration channels to be used when treating water of different qualities, thereby reducing filtration costs (water of good quality does not need to be filtered through the softening resin layer 310, thus avoiding wasting the number of filtrations of the softening resin layer 310, thereby reducing filtration costs).

[0024] like Figure 2 As shown, when the raw water quality is good, the user drives the diverter 500 to move to the first position, the third inlet 430 of the third channel 400 is connected to the first outlet 220 of the first channel 200, the diverter 500 closes the second outlet 330 of the second channel 300, the raw water enters the first channel 200 in the filter cartridge 100 through the raw water inlet 110 and the first inlet 210, and the raw water discharged from the first channel 200 enters the third channel 400 through the first outlet 220 and the third inlet 430. After the raw water enters the third channel 400, the raw water will be filtered through the activated carbon layer 410, and the filtered pure water will be discharged from the filter cartridge 100 through the third outlet 420 and the pure water outlet 120. like Figure 1 As shown, when the raw water quality is poor, the user drives the diverter 500 to move to the second position, the third inlet 430 connects with the second outlet 330, the diverter 500 closes the first outlet 220, and the raw water enters the second flow channel 300 in the filter cartridge 100 through the raw water inlet 110 and the second inlet 320. After entering the second flow channel 300, the raw water will be softened by the softening resin layer 310. The softened water enters the third flow channel 400 through the second outlet 330 and the third inlet 430. After entering the third flow channel 400, the softened water is filtered through the activated carbon layer 410. The filtered pure water is discharged from the filter cartridge 100 through the third outlet 420 and the pure water outlet 120.

[0025] It is understandable that the flow divider 500 is movably disposed on the filter cartridge 100, meaning that the flow divider 500 is rotatably disposed on the filter cartridge 100 or the flow divider 500 is movablely disposed on the filter cartridge 100.

[0026] Furthermore, the filter cartridge 100 has a first cavity 130 and a second cavity 140, a first flow channel 200 and a second flow channel 300 are both located on the first cavity 130, a second inlet 320 is connected to the raw water inlet 110 through the first flow channel 200, and a third flow channel 400 is located on the second cavity 140.

[0027] Since both the first flow channel 200 and the second flow channel 300 are located on the first cavity 130, the space inside the first cavity 130 is fully utilized.

[0028] Furthermore, the diverter 500 is movably disposed between the first cavity 130 and the second cavity 140 to make full use of the space between the first cavity 130 and the second cavity 140.

[0029] Furthermore, such as Figure 1 As shown, the diverter 500 is rotatably disposed between the first cavity 130 and the second cavity 140, so that the diverter 500 does not need to occupy space in the vertical direction, and the volume of the coffee machine in the vertical direction can be reduced. If it is moved, the diverter 500 needs to move in the vertical direction, which means that the diverter 500 needs to occupy space in the vertical direction.

[0030] Furthermore, such as Figure 1 As shown, a portion of the diverter 500 is located inside the filter cartridge 100, while another portion of the diverter 500 is located outside the filter cartridge 100.

[0031] Since the other part of the diverter 500 is located outside the filter cartridge 100, the user can drive the diverter 500 through the other part of the diverter 500, thus achieving the effect of conveniently driving the diverter 500 to rotate.

[0032] Furthermore, such as Figure 1 As shown, the filter cartridge 100 has a third cavity 150, which is located between the first cavity 130 and the second cavity 140; The first cavity 130 is connected to the third cavity 150 through the first outlet 220 and the second outlet 330; The third inlet 430 is configured as two, and the second cavity 140 is connected to the third cavity 150 through the two third inlets 430; The flow divider 500 is rotatably mounted on the third cavity 150, and the flow divider 500 has a fourth flow channel 510; like Figure 2 As shown, in the first position, the first outlet 220 is connected to one of the third inlets 430 (α), and the diverter 500 closes the second outlet 330; like Figure 1 As shown, in the second position, the second outlet 330 is connected to another third inlet 430 (β) through the fourth flow channel 510 and the space γ between the outer wall of the diverter 500 and the inner wall of the third cavity 150, and the diverter 500 closes the first outlet 220.

[0033] With the above configuration, it is convenient to make full use of the space between the first cavity 130 and the second cavity 140, and also to switch the third flow channel 400 to be connected to the first flow channel 200 or the second flow channel 300 by driving the flow divider 500 to rotate.

[0034] It is understandable that, in the first position, the connection between the first outlet 220 and one of the third inlets 430 (α) means that when the diverter 500 is rotated to the first position, the diverter 500 connects the first outlet 220 with one of the third inlets 430 (α). That is, the first outlet 220 can only be connected to one of the third inlets 430 (α) through the diverter 500.

[0035] Furthermore, such as Figure 1 As shown, the first outlet 220 and one of the third inlets 430 (α) are located at the bottom of the third cavity 150, the other third inlet 430 (β) is located above the first outlet 220 and one of the third inlets 430 (α), the second outlet 330 is located above the other third inlet 430 (β), and the position of the inlet of the fourth flow channel 510 corresponds to the position of the second outlet 330. The bottom of the diverter 500 has a threaded section 520, which is threadedly connected to the inner wall of the third cavity 150. The threaded section 520 is located between the two third inlets 430. The bottom of the third cavity 150 has a connecting channel 101 located below the diverter 500 and extending horizontally. The inlet of the connecting channel 101 is connected to the first outlet 220, and the outlet of the connecting channel 101 is connected to one of the third inlets 430. The upper end of the middle part of the connecting channel 101 has an opening, and the opening is provided with a silicone gasket sealing gasket 151 on the bottom surface. like Figure 2 As shown, in the first position, the bottom of the diverter 500 is away from the sealing gasket 151, the first outlet 220 is connected to one of the third inlets 430 (α) through the connecting channel 101, the position of the inlet of the fourth flow channel 510 is offset from the position of the second outlet 330, and the side wall of the diverter 500 closes the second outlet 330. like Figure 1 As shown, in the second position, the bottom of the diverter 500 presses down the sealing gasket 151, the sealing gasket 151 closes the communication channel 101, and the inlet and outlet of the fourth channel 510 are connected to the second outlet 330 and another third inlet 430 (β), respectively.

[0036] like Figure 2As shown, when the raw water quality is good, the user drives the diverter 500 to rotate, moving it to the first position, causing it to move upwards and its bottom away from the sealing gasket 151. At this time, the sealing gasket 151, under the action of elastic recovery, does not close the connecting channel 101. The first outlet 220 is connected to one of the third inlets 430 (α) through the connecting channel 101. The position of the inlet of the fourth flow channel 510 is offset from the position of the second outlet 330. The second outlet 330 is closed on the side wall of 500. Raw water enters the first flow channel 200 in the filter cartridge 100 through the raw water inlet 110 and the first inlet 210. The raw water discharged from the first flow channel 200 enters the third flow channel 400 through the first outlet 220, the connecting channel 101 and one of the third inlets 430 (α). After entering the third flow channel 400, the raw water is filtered through the activated carbon layer 410. The filtered pure water is discharged from the filter cartridge 100 through the third outlet 420 and the pure water outlet 120. like Figure 1 As shown, when the raw water quality is poor, the user drives the diverter 500 to rotate, moving it to the second position. This causes the diverter 500 to move downwards, pressing down on the sealing gasket 151. The sealing gasket 151 closes the connecting channel 101, preventing the first outlet 220 from connecting with one of the third inlets 430 (α). Simultaneously, due to the downward movement of the diverter 500, the inlet position of the fourth channel 510 corresponds to the position of the second outlet 330. Consequently, the inlet and outlet of the fourth channel 510 connect with the second outlet 330 and another third inlet 430 (β), respectively, allowing the raw water to flow through. The raw water enters the second flow channel 300 inside the filter cartridge 100 through the raw water inlet 110 and the second inlet 320. After entering the second flow channel 300, the raw water will be softened by the softening resin layer 310. The softened water enters the fourth flow channel 510 through the second outlet 330, and then flows downward along the space (γ) between the outer wall of the diverter 500 and the inner wall of the third cavity 150. Then it enters the third flow channel 400 through another third inlet 430 (β). After entering the third flow channel 400, the softened water is filtered through the activated carbon layer 410. The filtered pure water is discharged from the filter cartridge 100 through the third outlet 420 and the pure water outlet 120.

[0037] Specifically, such as Figure 3 As shown, the connecting channel 101 is a long strip extending in the left and right direction when viewed from above. The sealing gasket 151 is circular, and the diameter of the sealing gasket 151 is greater than the width of the connecting channel 101 in the front and back direction. The bottom of the diverter 500 is conical, and the lowest end of the diverter 500 is flat. When the bottom of the diverter 500 presses down on the sealing gasket 151, the diverter 500 causes the sealing gasket 151 to extend into the connecting channel 101. The part of the bottom of the diverter 500 that extends into the connecting channel 101 can squeeze the sealing gasket 151, causing the sealing gasket 151 to block the connecting channel 101, so that the left and right sides of the connecting channel 101 are not connected.

[0038] Specifically, such as Figure 1 As shown, two supports 600 are spaced apart in the vertical direction, and the outer walls of the two supports 600 are threadedly connected to the inner wall of the third cavity 150. The space between the two supports 600 forms a connecting channel 101.

[0039] Furthermore, such as Figure 1 As shown, the second outlet 330 is provided with a sealing ring 331 to facilitate the closure of the second outlet 330 by the diverter 500, thus making it easy for the diverter 500 to close the second outlet 330.

[0040] Furthermore, such as Figure 1 As shown, the second cavity 140 has a partition 141 in the middle, which extends upward. There is a gap between the upper end of the partition 141 and the upper wall of the second cavity 140. The pure water outlet 120 is located to the left of the partition 141 and the bottom of the second cavity 140. Two third inlets 430 are located to the right of the partition 141. The inner wall of the second cavity 140 and the partition 141 enclose a third flow channel 400.

[0041] By providing a baffle 141 to extend the third flow channel 400, the activated carbon layer 410 can be fully filtered for water.

[0042] Furthermore, such as Figure 2 As shown, another part of the diverter 500 is provided with a handle 530 to facilitate driving the diverter 500 to rotate.

[0043] Furthermore, the second flow channel 300 and / or the third flow channel 400 are also provided with several filter media to perform different filtrations on the water. For example, the third flow channel 400 is also provided with a filter media, which is a post-filter cartridge located downstream of the activated carbon layer 410.

[0044] When this utility model is in operation: like Figure 2As shown, when the raw water quality is good, the user drives the diverter 500 to rotate by the handle 530, driving the diverter 500 to the first position, so that the diverter 500 moves upward and the bottom of the diverter 500 moves away from the sealing gasket 151. At this time, the first outlet 220 is connected to one of the third inlets 430 (α) through the connecting channel 101. The side wall of the diverter 500 closes the second outlet 330. The raw water enters the first flow channel 200 in the filter cartridge 100 through the raw water inlet 110 and the first inlet 210. The raw water discharged from the first flow channel 200 enters the third flow channel 400 through the first outlet 220 and one of the third inlets 430 (α). After the raw water enters the third flow channel 400, the raw water is filtered through the activated carbon layer 410. The filtered pure water is discharged from the filter cartridge 100 through the third outlet 420 and the pure water outlet 120. like Figure 1 As shown, when the raw water quality is poor, the user drives the diverter 500 to rotate via handle 530, moving it to the second position and causing it to move downwards. The diverter 500 causes the sealing gasket 151 to close the connecting channel 101. The sealing gasket 151 prevents the first outlet 220 from connecting with one of the third inlets 430 (α). The inlet and outlet of the fourth channel 510 are connected to the second outlet 330 and another third inlet 430 (β), respectively. Raw water enters the first channel 200 through the raw water inlet 110 and the first inlet 210. Because the second outlet 330 of the first channel 200 is closed, the first… The raw water in the flow channel 200 enters the second flow channel 300 through the second inlet 320. After entering the second flow channel 300, the raw water will be softened by the softening resin layer 310. The softened water enters the fourth flow channel 510 through the second outlet 330, and then flows downward along the space (γ) between the outer wall of the diverter 500 and the inner wall of the third cavity 150. Then it enters the third flow channel 400 through another third inlet 430 (β). After entering the third flow channel 400, the softened water is filtered through the activated carbon layer 410. The filtered pure water is discharged from the filter cartridge 100 through the third outlet 420 and the pure water outlet 120.
