[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3This utility model provides an embodiment of a miniature flow regulating valve, comprising a valve body 10. An inlet 101 is provided on the surface of the valve body 10, serving as the inlet for fluid to flow into the regulating valve and providing a fluid source for subsequent flow regulation. A first chamber 102 is located at the center of the valve body 10. This first chamber 102 is an important space for temporary storage and regulation of the fluid after it flows in. The outer wall of a first sealing ring 301 contacts the inner side wall of the first chamber 102, providing a seal to prevent fluid leakage from gaps between the first chamber 102 and other components. The first chamber 102 is connected to the inlet 101 and a sensor interface 104, allowing fluid flowing in from the inlet 101 to enter the first chamber 102. Simultaneously, the sensor can monitor relevant parameters of the fluid within the first chamber 102 through the sensor interface 104. A second chamber 203 is connected to the outlet 103, serving as the outlet for regulated fluid. The converging space guides the fluid to the outlet 103 for discharge. The outlet 103 is provided at the end of the valve body 10 away from the inlet 101. The outlet 103 is the channel for the regulated fluid to flow out of the regulating valve. The surface of the valve body 10 is provided with a sensor interface 104. The sensor interface 104 can be used to install different types of sensors, such as NTC temperature sensors or TDS water quality sensors, to obtain information such as fluid temperature and water quality. The top surface of the valve body 10 is provided with a valve core port 105. The valve core port 105 provides a position for the installation of the valve core 20, and the valve core 20 can be detachably installed on its inner wall, which facilitates the installation, disassembly and maintenance of the valve core 20. The inner wall of the top of the valve core 20 can be detachably installed with a motor 40. The motor 40 serves as the power source for the regulating valve and provides power for the rotation of the valve core 20. The bushing of the motor 40 is installed inside the motor mounting groove 204 to ensure a stable connection between the motor 40 and the valve core 20, and to accurately drive the valve core 20 to rotate.

[0035] Reference Figure 3 and Figure 4A second sealing groove 202 is provided on the upper side of the outer arc surface of the valve core 20. This second sealing groove 202 is used to install the second sealing ring 302, further enhancing the sealing performance between the valve core 20 and the valve body 10. The first sealing ring 301 is sleeved on the outer arc surface of the first sealing groove 201, and the outer wall of the first sealing ring 301 contacts the inner side wall of the first chamber 102, again emphasizing the role of the first sealing ring 301 in sealing the first chamber 102. The second sealing ring 302 is sleeved on the surface of the second sealing groove 202, and the outer wall of the second sealing ring 302 contacts the inner side wall of the first chamber 102. This double sealing structure ensures that fluid will not leak from the gap between the valve core 20 and the first chamber 102. A first channel 205 is provided on the inner side of the valve core 20. The first channel 205 is one of the important channels for fluid flow inside the valve core 20, providing a path for fluid to flow from the first chamber 102 to the second chamber 203. A motor mounting point is provided on the upper end face of the valve core 20. The groove 204 precisely provides the mounting position for the bushing of the motor 40, ensuring that the motor 40 can stably drive the valve core 20 to rotate. A first sealing groove 201 is provided on the lower side of the outer arc surface of the valve core 20, which works together with the second sealing groove 202 on the upper side to form a sealing structure at different positions of the valve core 20. A second chamber 203 is provided at the center of the outer arc surface of the valve core 20. The second chamber 203 is a transition space for the convergence and outflow of the regulated fluid. A rotating channel 206 is provided on the surface of the second chamber 203. The rotating channel 206 cooperates with the first channel 205, so that the fluid can flow from the first chamber 102 to the second chamber 203 along a predetermined path during the rotation of the valve core 20. The second chamber 203 is connected to the first chamber 102 through the first channel 205 and the rotating channel 206. This connection structure is the key to realizing flow regulation. By rotating the valve core 20, the flow area of ​​the channel is changed, thereby regulating the flow rate.

[0036] Working principle: When the motor 40 is started, the bushing of the motor 40 is in the motor mounting groove 204, which drives the valve core 20 to rotate. When the valve core 20 rotates, the relative position of the first channel 205 and the rotating channel 206 changes, thereby changing the flow area of ​​the channel. The fluid enters from the first chamber 102, flows into the second chamber 203 through the first channel 205 and the rotating channel 206, and then flows from the second chamber 203 to the outlet 103 for discharge. By controlling the rotation angle and speed of the motor 40, the rotation position of the valve core 20 can be precisely adjusted, thereby changing the flow area of ​​the channel and realizing the regulation of the fluid flow rate. At the same time, the fluid after flow regulation converges in the second chamber 203 and then flows out of the regulating valve through the outlet 103 connected to the second chamber 203, completing the entire process of flow regulation and fluid transmission.

[0037] The first sealing ring 301 and the second sealing ring 302 together form a double sealing structure. When the valve core 20 is installed at the valve core port 105 of the valve body 10, the first sealing ring 301 and the second sealing ring 302 are tightly fitted to the inner side wall of the first chamber 102 to prevent fluid from leaking from the gap between the valve core 20 and the first chamber 102, ensuring that the fluid flows in the predetermined channel and guaranteeing the accuracy and stability of flow regulation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
