In some embodiments of the present invention, the housing 100 is provided with an internal thread and the flow control ring 200 is provided with an external thread matching the internal thread, and the flow control ring 200 is threadedly mounted in the housing 100, so that the flow control ring 200 can be stably and detachably mounted in the housing 100, and the position of the flow control ring 200 in the axial direction of the housing 100 can be adjusted by rotating the flow control ring 200.
Further, as shown in fig. 3, a position adjustment concave hole 220 is provided on an end surface of the flow control ring 200 facing the outside of the housing 100. For example, the flow control ring 200 is disposed adjacent to the water inlet 110, and an end surface of the flow control ring 200 facing out of the water inlet 110 is provided with two regulating recesses 220 opposed in a radial direction of the flow control ring 200. It is thereby possible to facilitate the user to rotate the flow control ring 200 from the outside with a tool to adjust the position of the flow control ring 200 in the axial direction of the housing 100.
In some specific examples of the present invention, as shown in fig. 1 to 3, the water inlet 110 and the water outlet 120 are respectively disposed at both ends of the housing 100, the side water inlet 130 is disposed on a side wall of the housing 100, and the flow control ring 200 is disposed between the side water inlet 130 and the water outlet 120. This makes it possible to diversify the water supply to the flow rate control device 10, and to expand the range of application of the flow rate control device 10. Specifically, the flow regulating device 10 can be inserted into a straight pipe to feed water into and discharge water from two ends, and the flow regulating device 10 can also be inserted into a three-way pipe to feed water into and discharge water from the end by-pass, so that different water inlet structure requirements can be met.
Further, as shown in fig. 3, the side water inlets 130 are plural, each side water inlet 130 extends in the axial direction of the housing 100, and the plural side water inlets 130 are arranged at intervals in the circumferential direction of the housing 100. Therefore, on one hand, the water inflow from the side part of the shell 100 can be increased, and on the other hand, all parts of the shell 100 in the circumferential direction can be filled with water, so that the water filling diversity is further increased, and the flow adjusting device 10 is convenient to install.
Optionally, as shown in fig. 1 to fig. 3, the flow rate adjusting device 10 further includes a support 400, a buckle 410 is disposed on the support 400, the support 400 is disposed at the water outlet 120, and the buckle 410 is buckled in the side water inlet 130, so as to stop the temperature-sensitive flow rate adjusting assembly 300 in the housing 100, and the support 400 can be inserted into or pulled out from one end of the water outlet 120 of the housing 100, which is convenient to assemble and disassemble.
In some embodiments of the present invention, as shown in fig. 1-3, the temperature-sensitive flow rate adjustment assembly 300 includes a stroke sleeve 310, a temperature-sensitive element 320, and a return elastic element 330.
The stroke sleeve 310 is movably provided in the housing 100 in the axial direction of the housing 100, and the stroke sleeve 310 cooperates with the flow rate adjustment hole 210 to adjust the opening degree of the flow rate adjustment hole 210. The temperature sensing element 320 is variable in volume according to temperature, and for example, the temperature sensing element 320 is paraffin. The temperature sensing element 320 is disposed in the housing 100, and the temperature sensing element 320 is in transmission connection with the stroke sleeve 310, and the temperature sensing element 320 pushes the stroke sleeve 310 toward the flow control ring 200 by self-expansion. The return spring 330 is disposed between the stroke sleeve 310 and the housing 100 and normally urges the stroke sleeve 310 toward the temperature sensing element.
When the water temperature of the casing 100 is high, the temperature sensing member 320 expands and pushes the stroke sleeve 310 to move toward the flow control ring 200, so that the opening degree of the flow control hole 210 is increased, thereby increasing the water flow rate. When the water temperature of the housing 100 is low, the temperature sensing element 320 contracts, the stroke sleeve 310 moves toward the temperature sensing element 320 under the action of the elastic return element 330, and the opening of the flow rate adjusting hole 210 is reduced, thereby reducing the water flow rate.
Alternatively, as shown in fig. 1 to fig. 3, the flow-regulating hole 210 is a tapered hole whose cross-sectional area gradually increases from the water outlet 120 to the water inlet 110, the stroke sleeve 310 is provided with a flow-regulating head 311 that is matched with the tapered flow-regulating hole 210, when the stroke sleeve 310 moves, the flow-regulating head 311 is driven to move relative to the flow-control ring 200, and the position of the flow-regulating head 311 in the flow-regulating hole 210 changes, so as to change the position of the flow-regulating head 311 in the flow-regulating hole 210, so as to adjust the opening degree of the flow-regulating hole 210.
Specifically, when the temperature of the water in the casing 100 is high, the temperature sensing element 320 expands and pushes the stroke sleeve 310 to move toward the flow control ring 200, the flow control head 311 moves toward a portion of the flow control hole 210 having a large diameter, the opening degree of the flow control hole 210 increases, and the flow rate of the water increases.
When the water temperature of the casing 100 is low, the temperature sensing element 320 contracts, the stroke sleeve 310 moves toward the temperature sensing element 320 under the action of the return elastic element 330, the flow rate adjusting head 311 moves toward the portion of the flow rate adjusting hole 210 with a smaller diameter, the opening of the flow rate adjusting hole 210 is reduced, and the water flow rate is reduced.
In some specific examples of the present invention, as shown in fig. 1 to 3, the temperature-sensitive flow rate adjusting assembly 300 further includes a temperature-sensitive housing 340, a flexible pad 350, and a transmission lever 360.
The temperature sensing element 320 is disposed in the temperature sensing housing 340 and the temperature sensing housing 340 is provided with a through hole. The flexible pad 350 is provided in the temperature sensing housing 340 between the temperature sensing piece 320 and the through hole. One end of the transmission rod 360 abuts on the stroke sleeve 310, and the other end of the transmission rod 360 passes through the through hole to abut on the flexible pad 350. Therefore, the temperature sensing element 320 can be installed and positioned, the expansion deformation of the temperature sensing element 320 can be transmitted to the stroke sleeve 310 by the transmission rod 360, and the stability of power transmission can be improved by arranging the flexible pad 350.
It will be understood by those skilled in the art that the temperature sensing housing 340, the flexible pad 350 and the transmission rod 360 are all heat conductive members in order for the temperature sensing element 320 to accurately sense the temperature of water in the housing 100.

This improves the stability of the engagement of the transmission rod 360 with the stroke sleeve 310, and prevents the one end of the transmission rod 360 from shifting in the radial direction of the bottom wall of the inner cavity 312, thereby improving the stability of the transmission.
In some embodiments of the invention. As shown in fig. 1-3, a sleeve boss 314 is disposed on an outer wall of the stroke sleeve 310, a housing boss 140 is disposed on an inner wall of the housing 100, the elastic restoring member 330 is a spring, the elastic restoring member 330 is sleeved on the stroke sleeve 310, and two ends of the elastic restoring member 330 respectively abut against the sleeve boss 314 and the housing boss 140, so as to implement installation and positioning of the elastic restoring member 330.
