[0028] like Figures 1 to 3 As shown, the utility model proposes a smart toilet companion large flow valve core, including a three-inlet and outlet angle valve, a valve core structure installed at the water outlet of the three-inlet and outlet angle valve, and a switch screw cap matched with the valve core structure, wherein the valve core structure includes a valve stem, a hollow fixing block, a hollow polygonal body block, a gasket and a fastener;

[0029] The hollow fixing block can be detachably installed on the water outlet of the three-inlet and outlet angle valve;

[0030] The valve stem is installed in the hollow fixed block;

[0031] The outer surface of the top of the valve stem is tightly matched with the inside of the switch screw cap, and the outer surface of the bottom of the valve stem is connected with the inner thread of the hollow polygonal body block;

[0032] The hollow polygonal body block and the hollow fixed block slide up and down in cooperation;

[0033] The gasket is fixed to the bottom end of the hollow polygonal body block through a fastener.

[0034] The outer surface of the top of the valve stem is in the shape of vertical teeth, and a groove with a clearance fit between the outer surface of the top of the valve stem and the switch screw cap is provided.

[0035] The valve stem and the inside of the hollow fixing block are snap-fitted, the valve stem is provided with a plurality of annular protrusions, and the hollow fixing block is provided with grooves matching with the plurality of annular protrusions.

[0036] The outer surface of the bottom of the valve stem is in the shape of a screw, and is connected to the inner thread of the hollow polygonal body.

[0037] The fastener is threadedly connected to the bottom of the hollow polygonal block.

[0038] The contact area between the fastener and the washer is approximately equal to 1 / 3 of the bottom area of ​​the washer.

[0039] The hollow polygonal body block is provided with an annular groove, and the top end of the annular groove is clamped at the bottom end of the hollow fixed block.

[0040] The hollow fixing block and the water outlet of the three-inlet and outlet angle valve are clearance-fitted or threadedly connected.

[0041] Working principle:

[0042] User operation and control transfer

[0043] The user controls the water flow by rotating the switch cap. The groove inside the switch cap fits tightly with the vertical toothed outer surface on the top of the valve stem, realizing direct transmission from the user's rotation to the valve stem rotation. This design ensures the sensitivity and accuracy of the operation, allowing the user to easily adjust the water flow and realize the flushing function.

[0044] Multifunctional stem design

[0045] As the core component of the operation transmission, the valve stem has a unique multifunctional design; the vertical toothed outer surface on the top cooperates with the groove in the switch screw cap, while the screw shape at the bottom is connected with the inner thread of the hollow polygonal block; the annular protrusion on the valve stem cooperates with the groove in the hollow fixing block, providing additional stability and guidance, ensuring that the valve stem remains stable when rotating, thereby accurately controlling the water flow;

[0046] Precise control of water flow

[0047] The hollow polygonal body slides up and down inside the hollow fixed block and is connected to the thread at the bottom of the valve stem, forming a precise adjustment mechanism. When the valve stem rotates, the hollow polygonal body moves up and down at a precise linear distance according to the angle and pitch of the thread. This up and down movement changes the opening degree of the valve core, thereby accurately controlling the water flow and flow rate. This allows users to easily adjust the water flow according to different usage requirements and achieve an efficient and water-saving flushing effect.

[0048] Gasket stability and maintenance

[0049] The gasket is fixed to the bottom of the hollow polygonal block by fasteners, and the fasteners are connected to the threads at the bottom of the hollow polygonal block, providing a stable fixing method; this design reduces the displacement or falling off of the gasket caused by water flow impact, and improves the reliability of sealing performance; the contact area between the fastener and the gasket is optimized to about 1 / 3 of the bottom area of ​​the gasket, reducing the contact area between the gasket and the fastener, reducing the wear caused by friction, and extending the service life of the gasket; when the gasket needs to be replaced, the user can easily remove the fastener and replace the new gasket without professional tools or complicated operations, reducing the difficulty and cost of maintenance;

[0050] Sealing and leak-proof enhancement

[0051] The ring groove design on the hollow polygonal block and its clamping fit with the hollow fixed block further enhance the sealing performance of the entire valve core structure; the top of the ring groove is clamped on the bottom of the hollow fixed block to form a double sealing structure, which effectively prevents water from leaking through the valve core; this double sealing structure ensures that the sealing performance does not decrease after long-term use, and can still maintain a good sealing effect even after the valve core has been working for a long time or has been worn to a certain extent;

[0052] Optimization of materials and processes

[0053] The utility model is optimized in material selection and process design; all parts in direct contact with water are made of corrosion-resistant and wear-resistant materials, ensuring stability and durability in long-term use; key connection parts such as threaded connection and bayonet fit are processed with high precision and strict quality control, ensuring the tightness and reliability of the connection, and reducing the risk of performance degradation or failure due to loose connection.
