[0034] Reference Figure 1 As shown, the water circuit structure according to an embodiment of the present invention includes multiple filter components 100, multiple first connecting components 200, and multiple second connecting components 300. The multiple filter components 100 include a filter element cover 110 and a filter element 150. The filter element 150 has a first inlet / outlet (not shown) and a second inlet / outlet (not shown). The filter element cover 110 has a first pipe 120 extending in a leftward direction and a second pipe 130 extending in a left-right direction. The middle portion of the first pipe 120 communicates with the first inlet / outlet, and the middle portion of the second pipe 130 communicates with the second inlet / outlet. The multiple first connecting components 200 include a plug 210, which is detachably installed at one end of the first pipe 120 or one end of the second pipe 130, and the plug 210 can seal one end of the first pipe 120 or one end of the second pipe 130. The multiple second connecting components 300 include a connecting member 310, such as... Figure 1 , 2As shown, the connecting member 310 has a through channel 320 extending in the left-right direction. When multiple filter components 100 are combined, a connecting member 310 is detachably connected between the first pipes 120 of two filter components 100 and / or a connecting member 310 is detachably connected between the second pipes 130 of two filter components 100.

[0035] By setting multiple plugs 210 and multiple connecting parts 310, operation can be performed according to the combination (series or parallel) of multiple filter components 100. Specifically, depending on the combination, the plugs 210 are used to seal one end of the first pipe 120 or the second pipe 130 that needs to be blocked; depending on the combination, the connecting parts 310 are used to connect two adjacent first pipes 120 or second pipes 130 that need to be connected. Thus, multiple filter cartridges are connected through multiple plugs 210 and multiple connecting parts 310, avoiding the use of more pipes and reducing the size of the water purification equipment. The filter cartridge cover 110 can adopt a uniform shape, with low development cost, and only needs to be used with the plugs 210 and connecting parts 310 to realize series or parallel filtration of raw water.

[0036] For example, such as Figure 1 As shown, each filter assembly 100 also includes a filter element 150, with a filter element cover 110 mounted on top of the filter element 150; as Figure 3 As shown, taking three filter components 100 as an example, they are defined as the first filter component 100 (α), the second filter component 100 (β), and the third filter component 100 (γ), respectively. The second filter component 100 (β) and the third filter component 100 (γ) are connected in parallel with the first filter component 100 (α). That is, after the raw water enters the first filter component 100 (α) for filtration, the filtered water simultaneously enters the second filter component 100 (β) and the third filter component 100 (γ). The water filtered by the second filter component 100 (β) and the water filtered by the third filter component 100 (γ) are discharged through a common pipe.

[0037] The specific configuration of plug 210 and connector 310 is as follows:

[0038] like Figure 3As shown, the left end of the first pipe 120 of the first filter assembly 100(α) is connected to the raw water. A plug 210 is provided on the right side of the first pipe 120 of the first filter assembly 100(α). A plug 210 is provided on the left end of the second pipe 130 of the first filter assembly 100(α). A connecting piece 310 connects the right end of the second pipe 130 of the first filter assembly 100(α) and the left end of the second pipe 130 of the second filter assembly 100(β). The right end of the second pipe 130 of the first filter assembly 100(α) and the left end of the second pipe 130 of the second filter assembly 100(β) are connected through the through channel 320 of the connecting piece 310. A plug 210 is provided on the left end of the first pipe 120 of the second filter assembly 100(β). A connection is provided between the right end of the first pipe 120 of the second filter assembly 100(β) and the left end of the first pipe 120 of the third filter assembly 100(γ). There is a connecting member 310. The right end of the first pipe 120 of the second filter assembly 100(β) and the left end of the first pipe 120 of the third filter assembly 100(γ) are connected through the through channel 320 of the connecting member 310. The right end of the second pipe 130 of the second filter assembly 100(β) and the left end of the second pipe 130 of the third filter assembly 100(γ) are connected through the through channel 320 of the connecting member 310. A plug 210 is provided at the right end of the second pipe 130 of the third filter assembly 100(γ). The right end of the first pipe 120 of the third filter assembly 100(γ) is used to discharge the water filtered by the first filter assembly 100(α), the second filter assembly 100(β) and the third filter assembly 100(γ).

[0039] At work, such as Figure 4 As shown, raw water enters the first filter assembly 100(α) from the left end of the first pipe 120 through the first pipe 120 for filtration. The filtered water then enters the second pipe 130 of the first filter assembly 100(α), and is discharged from the right end of the second pipe 130 of the first filter assembly 100(α). The water then passes through the connecting piece 310 and enters the second pipe 130 of the second filter assembly 100(β) from the left end of the second pipe 130. Finally, the water enters the second filter assembly 100(β) through the second pipe 130 for filtration.

[0040] Simultaneously, since the second pipe 130 of the second filter assembly 100(β) and the second pipe 130 of the third filter assembly 100(γ) are connected by a connecting member 310, the water filtered by the first filter assembly 100(α) also enters the second pipe 130 of the third filter assembly 100(γ) from the right end of the second pipe 130 of the second filter assembly 100(β) through the connecting member 310. This allows the water filtered by the first filter assembly 100(α) to also enter the third filter assembly 100(γ) for filtration. The water filtered by the second filter assembly 100(β) enters the first pipe 120 of the second filter assembly 100(β) and enters the first pipe 120 of the third filter assembly 100(γ) through the right end of the first pipe 120 and the connecting member 310, where it merges with the water filtered by the third filter assembly 100(γ). Consequently, the water filtered by the second filter assembly 100(β) and the water filtered by the third filter assembly 100(γ) are both discharged from the right end of the first pipe 120 of the third filter assembly 100(γ).

[0041] Specifically, the first pipe 120 and the second pipe 130 on the filter cover 110 are spaced apart in the front-to-back direction.

[0042] It is understandable that, such as Figure 3 As shown, the plug 210 can be installed at one end of the first pipe 120 or one end of the second pipe 130 depending on the combination of multiple filter components 100. For example, when raw water needs to enter the filter component 100 through the first pipe 120 of the first filter component 100 (α), the left end of the first pipe 120 is open, and the right end of the first pipe 120 is provided with a plug 210. Then, the raw water enters the first pipe 120 from the left end of the first pipe 120 and enters the first filter component 100 (α) through the first pipe 120.

[0043] It is understood that the connecting element 310 can be located between two adjacent first pipes 120 or between two adjacent second pipes 130, depending on the connectivity of two adjacent filter components 100.

[0044] For example, when the second filter assembly 100(β) and the third filter assembly 100(γ) need to pass water filtered by the first filter assembly 100(α), a plug 210 is provided at the left end of the second pipe 130 of the first filter assembly 100(α), the right end of the second pipe 130 of the first filter assembly 100(α) is connected to the left end of the second pipe 130 of the second filter assembly 100(β) through a connecting member 310, the right end of the second pipe 130 of the second filter assembly 100(β) is connected to the left end of the second pipe 130 of the third filter assembly 100(γ) through a connecting member 310, and a plug 210 is provided at the right end of the second pipe 130 of the third filter assembly 100(γ). During operation, water filtered by the first filter assembly 100(α) enters the second pipe 130 of the second filter assembly 100(β) through the connecting piece 310 on the left side of the second filter assembly 100(β). At the same time, water filtered by the first filter assembly 100(α) enters the second pipe 130 of the third filter assembly 100(γ) through the second pipe 130 of the second filter assembly 100(β) and the connecting piece 310 on the right side of the second filter assembly 100(β). Due to the blockage 210 on the right side of the second pipe 130 of the third filter assembly 100(γ), water filtered by the first filter assembly 100(α) will enter both the second filter assembly 100(β) and the third filter assembly 100(γ).

[0045] It is understandable that both the first and second inlets / outlets can serve as the inlet or outlet for filter element 150.

[0046] For example, such as Figure 3 As shown, raw water enters the filter element 150 through the first pipe 120 and the first inlet / outlet (equivalent to the inlet) of the first filter assembly 100(α). After being filtered by the filter element 150, the raw water is discharged through the second pipe 130 and the second inlet / outlet (equivalent to the outlet) of the first filter assembly 100(α).

[0047] For example, as shown in Figure 3, the water filtered by the first filter element 100 (α) enters the filter element 150 through the second pipe 130 and the second inlet / outlet (equivalent to the inlet) of the second filter element 100 (β), and the water filtered by the filter element 150 is discharged through the first pipe 120 and the first inlet / outlet (equivalent to the outlet) of the second filter element 100 (β).

[0048] In some embodiments of this utility model, such as Figure 1 , 5 As shown, both the left and right ends of the first pipe 120 and both the left and right ends of the second pipe 130 have a first snap-fit ​​portion 140.

[0049] The first connecting component 200 also includes a second snap-fit ​​portion 220, which is detachably mounted on the plug 210. The second snap-fit ​​portion 220 and the first snap-fit ​​portion 140 corresponding to the plug 210 are snap-fit ​​connected.

[0050] The second connecting component 300 also includes a third snap-fit ​​portion 330, which is detachably mounted on the connecting member 310. The third snap-fit ​​portion 330 and the first snap-fit ​​portion 140 corresponding to the connecting member 310 are snap-fit ​​connected.

[0051] By providing a second snap-fit ​​part 220 and a first snap-fit ​​part 140, the second snap-fit ​​part 220 can be snapped into connection with the first snap-fit ​​part 140, thereby fixing the plug 210 to one end of the first pipe 120 or one end of the second pipe 130.

[0052] For example, such as Figure 3 As shown, the plug 210 needs to be installed on the right end of the first pipe 120. During installation, the plug 210 is installed on the right end of the first pipe 120, and the second snap-fit ​​part 220 corresponds to the position of the first snap-fit ​​part 140 on the first pipe 120. The second snap-fit ​​part 220 is installed on the plug 210 and snap-fits with the first snap-fit ​​part 140, thereby fixing the plug 210 to the first pipe 120.

[0053] By providing a third snap-fit ​​part 330 and a first snap-fit ​​part 140, the third snap-fit ​​part 330 can be snapped into connection with the first snap-fit ​​part 140, thereby fixing the connecting member 310 to one end of the first pipe 120 or one end of the second pipe 130.

[0054] For example, such as Figure 3 As shown, when two adjacent second pipes 130 need to be connected, the left end of the connecting member 310 is connected to the right end of the second pipe 130 on the left, and the right end of the connecting member 310 is connected to the left end of the second pipe 130 on the right. One third snap-fit ​​part 330 corresponds to the position of the first snap-fit ​​part 140 on the second pipe 130 on the left and snaps-fits it. The other third snap-fit ​​part 330 corresponds to the position of the first snap-fit ​​part 140 on the second pipe 130 on the right and snaps-fits it. By snapping-fitting the two third snap-fit ​​parts 330 with the two first snap-fit ​​parts 140, the connecting member 310 is installed on the two adjacent second pipes 130.

[0055] In a further embodiment of this utility model, such as Figure 5 As shown, the outer sides of both ends of the first pipe 120 and the outer sides of both ends of the second pipe 130 have grooves 121, and the grooves 121 are the first snap-fit ​​parts 140.

[0056] like Figure 7As shown, the plug 210 has an installation cavity 211 with one end open. One end of the first pipe 120 or one end of the second pipe 130 is inserted into the installation cavity 211. The second snap-fit ​​part 220 can pass through the plug 210 and snap-fit ​​with the corresponding groove 121.

[0057] The second snap-fit ​​part 220 engages with the groove 121 to achieve a snap-fit ​​connection, which facilitates the installation of the plug 210. When installing or removing the plug 210, only the second snap-fit ​​part 220 needs to be removed or installed.

[0058] For example, the plug 210 needs to be installed on the left end of the second pipe 130. During installation, the left end of the second pipe 130 is inserted into the mounting cavity 211 of the plug 210, and the second snap-fit ​​part 220 passes through the plug 210 and snaps into the groove 121 on the second pipe 130. In this way, the second snap-fit ​​part 220 restricts the movement of the plug 210, thereby installing the plug 210 on the second pipe 130.

[0059] Specifically, the groove 121 can be an annular groove, and the second snap-fit ​​part 220 can be C-shaped.

[0060] In a further embodiment of the present invention, the plug 210 has a first insertion channel 212 that facilitates the second snap-fit ​​portion 220 to pass through the plug 210 and snap-fit ​​into the groove 121.

[0061] The first insertion channel 212 facilitates the snap-fit ​​connection between the second snap-fit ​​part 220 and the groove 121, making it easy to install and remove the plug 210.

[0062] In a further embodiment of this utility model, such as Figure 7 As shown, one end of the first pipe 120 or one end of the second pipe 130 is inserted into the through channel 320, and the third snap-fit ​​part 330 can pass through the connecting member 310 and its corresponding groove 121 for snap-fit ​​connection.

[0063] The connecting piece 310 is sleeved outside the first pipe 120 or the second pipe 130, so that the third snap-fit ​​part 330 can pass through the connecting piece 310 and snap-fit ​​with the groove 121, which facilitates the installation and removal of the connecting piece 310.

[0064] For example, such as Figure 7 As shown, one end of the first pipe 120 or one end of the second pipe 130 is inserted into one end of the through channel 320, and the third snap-fit ​​part 330 passes through the connecting member 310 and snaps into the groove 121 on the first pipe 120 or the groove 121 on the second pipe 130.

[0065] In a further embodiment of this utility model, such as Figure 5 As shown, the connecting member 310 has a second insertion channel 311 that facilitates the third snap-fit ​​portion 330 to pass through the connecting member 310 and snap-fit ​​into the groove 121.

[0066] The second insertion channel 311 facilitates the snap-fit ​​connection between the third snap-fit ​​part 330 and the groove 121, making it easy to install and remove the connecting piece 310.

[0067] In some embodiments of this utility model, such as Figure 7 As shown, a first sealing ring 213 is provided between the inner wall of the mounting cavity 211 of the plug 210 and the outer wall of the first pipe 120 or the outer wall of the second pipe 130.

[0068] By providing a first sealing ring 213, the gap between the plug 210 and the first pipe 120 or the second pipe 130 can be sealed by the first sealing ring 213, thereby preventing water leakage.

[0069] A second sealing ring 321 is provided between the inner wall of the through channel 320 of the connecting member 310 and the outer wall of the first pipe 120 or the outer wall of the second pipe 130.

[0070] By providing a second sealing ring 321, the gap between the connecting member 310 and the first pipe 120 or the second pipe 130 can be sealed by the second sealing ring 321 to prevent water leakage.

[0071] In a further embodiment of the present invention, there are multiple first sealing rings 213 and multiple second sealing rings 321, and the multiple first sealing rings 213 are spaced apart in the left-right direction.

[0072] By setting multiple first sealing rings 213 and multiple second sealing rings 321 in the left and right directions, multiple waterproofing effects can be achieved, thereby improving the sealing performance.

[0073] In some embodiments of this utility model, such as Figure 1 As shown, the outer side of the first pipe 120 has a first connecting hole 122 that communicates with the interior of the first pipe 120 and extends in the vertical direction, and the outer side of the second pipe 130 has a second connecting hole 131 that communicates with the interior of the second pipe 130 and extends in the vertical direction.

[0074] By providing a first connecting hole 122 and a second connecting hole 131, a pressure gauge or other detection device can be installed on the first connecting hole 122 or the second connecting hole 131, making it convenient to detect the condition inside the first pipe 120 or the second pipe 130.

[0075] In some embodiments of this utility model, the connecting member 310 has a bypass pipe 312, one end of which is connected to the through channel 320, and the other end of which is connected to the outside of the connecting member 310.

[0076] By providing a bypass pipe 312, filtered water can be extracted from the connecting member 310.
