[0026] The middle column 51 is hollow, and the control structure 5 includes a control rod 54 arranged in the middle column 51. The control rod 54 is provided with a pressure rod 55 in contact with the end of the rotating rod 53. The end of the rotating rod 53 away from the plug 4 is located inside the middle column 51. The middle column 51 is provided with a straight groove 56, and the rotating rod 53 is located in the straight groove 56; the lifting and lowering of the control rod 54 drives the pressure rod 55 to move, and the pressure rod 55 pushes the end of the rotating rod 53 located in the middle column 51 to rotate, thereby controlling the rotation of the rotating rod 53. A counterweight block is installed on the rotating rod 53. When the pressure rod 55 no longer presses down the rotating rod 53, under the action of gravity, the counterweight block and the plug 4 descend under the action of gravity and fall into the water outlet 31, and the water outlet 31 is blocked by the plug 4.

[0027] A main water inlet 32 ​​is provided below the middle column 51, a main water pipe 33 is provided on the main water inlet 32, a branch water pipe 34 is provided on the water outlet 31, a connecting water pipe 35 is provided between the main water pipe 33 and the branch water pipe 34, and a one-way cover plate 36 is provided at the connection between the main water pipe 33 and the branch water pipe 34; when it is necessary to achieve a three-way connection, it is only necessary to open the main water inlet 32, and the liquid in the valve housing 2 will flow into the branch water pipe 34 through the main water pipe, and a one-way cover plate 36 is provided between the main water pipe and the branch water pipe 34 to prevent the liquid in the branch water pipe 34 from flowing back, and the one-way cover plate 36 is a cover with the top hinged in the main water pipe, and the one-way cover plate 36 covers the connection port of the main water pipe 33 and the branch water pipe 34, which can effectively prevent the liquid in the branch water pipe 34 from flowing back to other branch water pipes 34 through the main water pipe 33 and the connecting water pipe 35.

[0028] A sealing plug 7 connected to a control rod 54 is provided in the middle column 51. The sealing plug 7 is located at the bottom of the middle column 51. A lifting piece 6 is provided at the top of the control rod 54. A connecting rod 5 is provided between the control rod 54 and the sealing plug 7. The main water outlet 32 ​​is blocked by the sealing plug 7, and the sealing plug 7 is pulled by the lifting piece 6 to achieve the purpose of opening and closing the main water outlet 32.

[0029] The lifting member 6 includes a pull-twist 61 arranged at the top end of the middle column 51. The pull-twist 61 is divided into a cap end 611 and a column end 612. The column end 612 is connected to the control rod 54. The cap end 611 is arranged on the surface of the valve cover 52. A pull rod 62 is arranged inside the cap end 611. The control rod 54 is driven to move by the pull-twist 61. At the same time, the cap end 611 is located on the surface of the valve cover 52. When it is necessary to pull the pull-twist 61, pulling the pull rod 62 can facilitate the operator to pull the pull-twist 61 up.

[0030] A piston 63 is provided at the bottom of the column end 612, and the control rod 54 passes through the piston 63 and is inserted into the column end 612. A top plate 64 is provided at the top of the control rod 54, and a contraction spring 65 is provided between the top plate 64 and the piston 63; a semi-arc groove is provided on the inner side of the middle column 51, and a spring ball matched with the groove is provided on the outer side of the piston 63. By utilizing the cooperation of the spring ball and the groove, the operator can sense the elasticity of the spring ball to achieve the purpose of sensing the rotation angle of the control rod 54. At the same time, the piston 63 can prevent the liquid from overflowing through the middle column 51 to avoid liquid overflow, and use the contraction spring 65 to pull the control rod 54 down, so that the control rod 54 receives a downward pulling force, ensuring that the control rod 54 can push the rotating rod 53 to rotate. At the same time, a slider is provided on the outer side of the top plate 64, and a sliding groove matched with the slider is provided on the inner wall of the middle column 51, ensuring that the control rod 54 can be driven to rotate while the pull-twist 61 rotates, thereby driving the pressure rod 55 to rotate.

[0031] A sealing ring plate 66 is provided in the middle column 51, and the piston 63 is fitted on top of the sealing ring plate 66. An ejection spring 67 is provided between the piston 63 and the valve cover 52, and a support rod 68 that passes through the valve housing 2 is provided at the bottom of the cap end 611; the sealing ring plate 66 and the piston 63 are fitted together, and the sealing ring plate 66 is used to support the piston 63 to avoid excessive descent, and the piston 63 can be squeezed by the ejection spring 67 to achieve a better sealing effect and avoid leakage. A plurality of plug holes that cooperate with the support rod 68 are also provided on the valve housing 2, and the distribution of the plug holes is the same as that of the grooves. When the total water outlet 32 ​​needs to be fully opened, it is only necessary to pull up the pull-twist 61 to make the support rod 68 completely pass through the plug hole, and rotate the pull-twist 61 until the support rod 68 does not correspond to the plug hole, so that the pull-twist 61 cannot drop. In this way, the sealing plug 4 can be kept unable to block the total water outlet 32, thereby achieving the purpose of the three-way connection.

[0032] The pressure rod 55 is divided into a double rod 551 and a single rod. The double rod 551 is two thin rods with an angle of 120°. The angle between the single rod and one of the thin rods in the double rod 551 is greater than 120°. A tilting rod 553 is provided between the pressure rod 55 and the control rod 54. A pressing groove is provided at one end of the rotating rod 53 located in the middle column 51. The end of the pressure rod 55 is located in the pressing groove. The number of rotating rods 53 is equal to the number of pressure rods 55. The double rod 551 is used to control the rotation of the two rotating rods 53 to open the two water outlets 31 to achieve double-pass. The single rod is used to control the opening of a single water outlet 31 to achieve single-pass. At the same time, the position of the groove in the middle column 51 can be used to determine the positions of the double rod 551 and the single rod, which is convenient for control. The presence of the groove can prevent the end of the pressure rod 55 from separating from the rotating rod 53 when the pressure rod 55 presses down the rotating rod 53.

[0033] The plug 4 is embedded in the water outlet 31. The plug 4 is in the shape of a truncated cone with a small bottom and a large top. The plug 4 is hinged to the end of the rotating rod 53, and the rotating rod 53 is hinged in the middle column 51 through an axis. The plug 4 of this shape can better block the water outlet 31 and can reduce the situation where the plug 4 cannot block the water outlet 31 due to fluctuation displacement and other reasons.

[0034] The technical effect of the present invention is: different plugs 4 are controlled to open by the control structure 5 to achieve the effect of a single-way, two-way or three-way valve, to achieve flexible control of the number of water outlet valve ports, and to use the gravity of the water in the valve to press on the plug 4 to avoid water leakage.
