For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1 As shown, a pressure differential automatic temperature-adjusting water mixing valve comprises a valve body 1, a fixed valve core sleeve 2, a dynamic water-adjusting sleeve 3 and a water-conducting fastener 4.

[0022] The valve body 1 includes a main body pipe 11 and a mixed water interface pipe 12. The mixed water interface pipe 12 is perpendicular to and connected to the main body pipe 11. A hot water inlet seat 13 and a cylindrical plug-in cavity 131 provided at the water outlet end of the hot water inlet seat 13 are provided in one end of the main body pipe 11. The water guide cavity of the hot water inlet seat 13 is connected to the cylindrical plug-in cavity 131.

[0023] The fixed valve core sleeve 2 is provided with a fixed cold water arc hole group 22 and a fixed hot water arc hole group 21. The fixed cold water arc hole group 22 is composed of two fixed cold water arc holes 221 distributed along the circumference, and the fixed hot water arc hole group 21 is composed of two fixed hot water arc holes 211; it can also be composed of more than three;

[0024] The dynamic water jacket 3 includes a hot water chamber 31, a dynamic arc-shaped hot water hole group 311, a cold water chamber 32 and a dynamic arc-shaped cold water hole group 321; the dynamic arc-shaped hot water hole group 311 is composed of two dynamic arc-shaped hot water holes 3111, and the dynamic arc-shaped cold water hole group 321 is composed of two dynamic arc-shaped cold water holes;

[0025] The water-conducting fastener 4 includes a circular fixing seat 41, a cold water hole 42 and a fixing cavity 43;

[0026] The cold water end of the fixed valve core sleeve 2 is inserted into the fixed cavity 43, and the dynamic water sleeve 3 is arranged in the fixed valve core sleeve 2 and slides together; the hot water end of the fixed valve core sleeve 2 is inserted into the cylindrical plug-in cavity 131, and the circular fixed seat 41 is detachably connected to the main pipe 11; the main pipe 11 between the water-conducting fastener 4 and the hot water inlet seat 13 constitutes a mixing water cavity, and the mixing water interface pipe 12 is connected to the mixing water cavity.

[0027] As a further improvement of the utility model: the width of the moving circular arc hot water holes of the moving circular arc hot water hole group 311 and the moving circular arc cold water holes of the moving circular arc cold water hole group 321 is greater than the width of the fixed cold water circular arc holes of the fixed cold water circular arc hole group 22 and the fixed hot water circular arc holes of the fixed hot water circular arc hole group 21. With such a structure, the dynamic water jacket is ensured to move and the water path is smooth.

[0028] As a further improvement of the present invention: the main body tube 11 is provided with an internal thread; the outer circumferential surface of the circular fixing seat 41 is provided with an external thread, and the cold water hole 42 is an internal hexagonal hole. The external thread and the internal thread are screwed together.

[0029] The movable arc-shaped hot water hole group 311, the movable arc-shaped cold water hole group 321, the fixed cold water arc-shaped hole group 22 and the fixed hot water arc-shaped hole group 21 are respectively provided in one group, and two or more groups may also be provided.

[0030] The valve body 1 and the water-conducting fastener 4 are made of brass, and the fixed valve core sleeve 2 and the dynamic water-adjusting sleeve 3 are made of stainless steel.

[0031] like Figure 1As shown, the hot water chamber 31 of the dynamic water jacket 3 corresponds to the hot water inlet seat 13 of the valve body, and hot water enters the fixed valve core sleeve 2 from the hot water inlet seat 13 and cold water enters from the water guide fastener 4 respectively; hot water enters the mixing water chamber through the hot water chamber 31, the dynamic arc-shaped hot water hole group 311, the dynamic arc-shaped hot water hole group 311 on the dynamic water jacket 3, and the fixed hot water arc-shaped hole group 21; cold water enters the mixing water chamber through the cold water chamber 32, the cold water chamber 32, the dynamic arc-shaped cold water hole group 321, and the fixed cold water arc-shaped hole group 22, and the cold water and the hot water are premixed in the mixing water chamber and then enter the mixing water interface pipe 12 for mixing;

[0032] like Figure 1 As shown, when in the center position, the dynamic arc-shaped hot water hole group 311 of the dynamic water regulating jacket 3 is flush with the left side of the fixed hot water arc-shaped hole group 21 of the fixed valve core sleeve 2, and the dynamic arc-shaped cold water hole group 321 is flush with the right side of the cold water arc-shaped hole group 22. When the cold water pressure decreases, the hot water side has a greater pressure than the cold water side, and the pressure difference between the left and right sides pushes the dynamic water regulating jacket 3 to move to the right, causing the dynamic arc-shaped hot water hole group 311 of the dynamic water regulating jacket 3 to be blocked by the fixed valve core sleeve 2. The fixed hot water arc hole group 21 of the fixed valve core sleeve 2 is blocked by the passive water regulating sleeve 3, so that the interactive outlet formed by the dynamic arc-shaped hot water hole group 311 and the fixed hot water arc-shaped hole group 21 becomes smaller, reducing the amount of hot water entering the mixing water chamber; and the dynamic arc-shaped cold water hole group 321 of the dynamic water regulating sleeve 3 is wider than the fixed cold water arc-shaped hole group 22 of the fixed valve core sleeve 2. Before the left side of the dynamic arc-shaped cold water hole group 321 is not flush with the left side of the fixed cold water arc-shaped hole group 22, the dynamic arc The size of the interactive outlet formed by the movable arc-shaped cold water hole group 321 and the fixed cold water arc-shaped hole group 22 remains unchanged, that is, the cold water with low water pressure has a larger outlet than the hot water outlet; when the pressure difference is large enough, the left side of the movable arc-shaped cold water hole group 321 of the dynamic water regulating jacket 3 is flush with the left side of the fixed cold water arc-shaped hole group 22 of the fixed valve core sleeve 2, when the dynamic water regulating jacket 3 continues to move to the right, the interactive outlet formed by the movable arc-shaped hot water hole group 311 and the fixed hot water arc-shaped hole group 21 and the interactive outlet formed by the movable arc-shaped cold water hole group 321 and the fixed cold water arc-shaped hole group 22 both begin to become smaller equally, and finally the interactive outlet formed by the movable arc-shaped hot water hole group 311 and the fixed hot water arc-shaped hole group 21 is completely closed, and the interactive outlet formed by the movable arc-shaped cold water hole group 321 and the fixed cold water arc-shaped hole group 22 still retains about half the size. From the beginning to the end, the hot water outlet is smaller than the cold water outlet, so as to achieve the purpose of balancing the water output on both sides and controlling the temperature of the mixed water. Vice versa, when the cold water pressure increases and the hot water pressure is smaller than the cold water pressure, the cold water outlet should be smaller than the hot water outlet throughout the process, and the water output on both sides is balanced, which can also achieve the purpose of controlling the mixed water temperature.

[0033] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
