[0035] Reference Figures 1 to 5 As shown, this embodiment provides a valve body structure, which includes a valve seat 100 and a filter cartridge 200 .

[0036] Specifically, the valve seat 100 is provided with a first channel 110, a liquid inlet 111 connected to the first end of the first channel 110, and a first liquid outlet 112 connected to the periphery of the first channel 110; a first support ring 210 is provided at one end of the filter cartridge 200, and a second support ring 220 is provided at the other end of the filter cartridge 200. The filter cartridge 200 is provided with a plurality of support ribs 230 spaced apart along the circumferential direction, the first end of the support rib 230 is connected to the first support ring 210, and the second end of the support rib 230 is connected to the second support ring 220, and the filter cartridge 200 is provided with a filter mesh 240 between adjacent support ribs 230; wherein, the filter cartridge 200 is arranged in the first channel 110, the first liquid outlet 112 is located between the first support ring 210 and the second support ring 220 along the axial direction of the filter cartridge 200, and the first support ring 210 is sealed with the liquid inlet 111.

[0037] In this embodiment, the first liquid outlet 112 is located between the first support ring 210 and the second support ring 220 along the axial direction of the filter cartridge 200, and the first support ring 210 is sealed with the liquid inlet 111, allowing liquid to stably flow into the filter cartridge 200 through the first support ring 210 and then flow through the filter screen 240 on the filter cartridge 200 to the first liquid outlet 112. Furthermore, the plurality of support ribs 230 connecting the first support ring 210 and the second support ring 220 provide good structural strength. When the first liquid outlet 112 is suddenly blocked, causing liquid to impact the filter cartridge 200, the support provided by the support ribs 230, the first support ring 210, and the second support ring 220 effectively prevents deformation of the filter screen 240, thereby ensuring the filtering effect of the filter cartridge 200 on the liquid.

[0038] In one feasible embodiment, the support ribs 230 are provided to protrude outwardly from the filter screen 240 along the radial direction of the filter cartridge 200, and the first support ring 210 and the second support ring 220 are both provided to protrude radially from the support ribs 230, so that a gap is formed between the filter screen 240 and the support ribs 230 and the inner surface of the first channel 110. Liquid in the filter cartridge 200 that flows through the filter screen 240 to the outside of the filter cartridge 200 can all flow out through the first liquid outlet 112. It is understandable that liquid between the outer periphery of the filter cartridge 200 and the inner surface of the first channel 110 can all flow out through the first liquid outlet 112. Even if the filter screen 240 is clogged in the radial direction of the filter cartridge 200 toward the first liquid outlet 112, the liquid can still flow out through the first liquid outlet 112 after passing through the filter screen 240 to the outside of the filter cartridge 200, so that the valve body structure can function normally.

[0039] In a feasible embodiment, the support rib 230 is provided with two protrusions 250 spaced apart along the axial direction of the filter cartridge 200, and the first liquid outlet 112 is located between the two protrusions 250 of the same support rib 230 along the axial direction of the filter cartridge 200, and the protrusion 250 is abutted against the inner surface of the first channel 110, which can form good support for the support rib 230, effectively prevent the support rib 230 from deformation, and further prevent the filter mesh 240 from deformation, thereby ensuring the filtering effect of the filter cartridge 200 on the liquid.

[0040] In a feasible embodiment, along the radial direction of the filter cartridge 200, one of the support ribs 230 is directed toward the first liquid outlet 112 and is arranged opposite the first liquid outlet 112, which can effectively prevent the filter mesh 240 opposite the first liquid outlet 112 from deforming, thereby ensuring the filtering effect of the filter cartridge 200 on the liquid.

[0041] In this embodiment, referring to Figures 3 to 5As shown, the filter screen 240 includes a plurality of arcuate ribs 241 spaced apart along the axial direction of the filter cartridge 200, and a plurality of vertical ribs 242 spaced apart along the circumference of the filter cartridge 200. The arcuate ribs 241 and the vertical ribs 242 intersect to form a plurality of filter holes 243, which facilitates the molding of the filter screen 240 and ensures that the filter cartridge 200 has sufficient filter holes 243 to ensure the water output of the valve body structure. Specifically, the ends of the arcuate ribs are connected to the corresponding support ribs 230, and one end of the vertical rib is connected to the first support ring 210, and the other end is connected to the second support ring 220.

[0042] For example, the first support ring 210, the second support ring 220, the support ribs 230, the protrusions 250, and the filter screen 240 are integrally injection molded to form the filter cartridge 200. The injection mold utilizes a top-to-bottom core-pulling and left-to-right mold-closing method to mold the filter cartridge 200. In this embodiment, during the injection molding of the filter cartridge 200, the size of the filter holes 243 can be adjusted by adjusting the spacing between adjacent vertical ribs 242 and the spacing between adjacent arcuate ribs 241, thereby adapting the filter cartridge 200 to various filtering requirements.

[0043] For example, one injection mold can simultaneously mold multiple filter cartridges 200 .

[0044] It is worth noting that the cross-sectional areas of the arcuate ribs 241 and the vertical ribs 242 are both smaller than the cross-sectional areas of the support ribs 230. This ensures that the filter cartridge 200 has sufficient filter holes 243 while also providing the filter cartridge 200 with good structural strength to prevent deformation of the filter screen 240. In this embodiment, during injection molding of the filter cartridge 200, the injection mold's injection port 10 can be aligned with the support ribs 230 or protrusions 250, effectively ensuring the molding quality of the filter cartridge 200.

[0045] For example, the cross-sectional area of ​​the arcuate rib 241 and the cross-sectional area of ​​the vertical rib 242 may be equal.

[0046] For example, the cross-sectional area of ​​the support rib 230 may be three to eight times, for example, four times, five times, or six times, the cross-sectional area of ​​the vertical rib 242 .

[0047] Exemplarily, the filter cartridge 200 is provided with three to eight supporting ribs 230 equidistantly along the circumference, such as four, five or six, to ensure that the filter cartridge has good structural strength.

[0048] In this embodiment, referring to Figure 1As shown, a sink groove 1111 is provided at the end of the liquid inlet 111, and a first support ring 210 is provided in the sink groove 1111. One end of the first support ring 210 facing the second support ring 220 along the axial direction of the filter cartridge 200 is abutted against the bottom of the sink groove 1111, so that a seal is formed between the first support ring 210 and the liquid inlet 111, and the positioning and assembly between the filter cartridge 200 and the valve seat 100 are facilitated.

[0049] For example, the liquid inlet 111 may be connected to a pipe joint by a threaded connection, and the first support ring 210 may be compressed by the pipe joint to form a good seal between the first support ring 210 and the liquid inlet 111 .

[0050] Illustratively, a clearance fit may be formed between the periphery of the first support ring 210 and the sidewall of the recessed groove 1111 , so as to facilitate placement of the first support ring 210 in the recessed groove 1111 .

[0051] In a feasible embodiment, the second support ring 220 is clearance-fitted with the first channel 110 , making it easy to insert the filter cartridge 200 into the first channel 110 .

[0052] In a feasible embodiment, the valve seat 100 is provided with a connection port 113 communicating with the second end of the first channel 110 to improve the applicability of the valve body structure. The pipe connector connected to the connection port 113 includes but is not limited to a Luer connector or a threaded connector.

[0053] In this embodiment, continue to refer to Figure 1 As shown, the valve seat 100 is further provided with a second channel 120 connected to the first liquid outlet 112 and a second liquid outlet 121 connected to the second channel 120, and a one-way valve 300 is provided in the second channel 120. The one-way valve 300 is configured to only allow the liquid in the first channel 110 to flow from the first liquid outlet 112 to the second liquid outlet 121, so as to prevent the liquid from flowing back from the second liquid outlet 121 to the first liquid outlet 112, which is stable and reliable.

[0054] Exemplarily, at least one second liquid outlet 121 is provided on the valve seat 100 , for example, two, to improve the applicability of the valve body structure.

[0055] Illustratively, the pipe joint connected to the second liquid outlet 121 includes but is not limited to a Luer joint or a threaded joint.

[0056] Specifically, the one-way valve 300 includes a valve stem 310, a sealing plate 320 mounted on the valve stem 310, and an elastic member 330 connected to the valve stem 310. The elastic member 330 forces the valve stem 310 to move toward the first liquid outlet 112. When the fluid pressure within the first channel 110 is lower than the fluid pressure within the second channel 120, the sealing plate 320, under the action of the elastic member 330, blocks the first liquid outlet 112. When the fluid pressure within the first channel 110 is higher than the fluid pressure within the second channel 120, the sealing plate 320 disengages from the first liquid outlet 112, allowing liquid to flow from the first liquid outlet 112 to the second liquid outlet 121.

[0057] Exemplarily, the elastic member 330 includes but is not limited to a spring or a spring.

[0058] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The specific contents of the above-mentioned specific embodiments only express several embodiments of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the appended claims.
