[0035] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0036] The utility model provides a dual-mode wire-controlled ultra-low drainage valve, such as Figures 1 to 9 As shown, it includes an ultra-low flushing mechanism 1, a foot-kick type pull switch 2, a hand-pressed pull switch 3, a first traction rope 4 and a second traction rope 5. The ultra-low flushing mechanism 1 in this case is connected to the foot-kick type and hand-pressed pull switches respectively through two traction ropes, which can control the opening and closing of the valve body individually or jointly to realize dual-mode mechanical control.
[0037] The ultra-low flushing mechanism 1 has a compact structure and is particularly suitable for low-tank toilets, such as Figures 1 to 3 As shown, the valve body includes a valve body and a valve stem 14 movably arranged in the valve body. Specifically, the valve body includes a base 11 and an upper shell 12. A water inlet 111 is arranged on the peripheral side of the base 11, and a water outlet 112 is located at the bottom of the base 11. The upper shell 12 is arranged on the upper part of the base 11, and has an inner cavity inside. A guide channel 121 is opened at the bottom of the inner cavity. This channel is used for the valve stem 14 to pass through, so as to ensure that the valve stem 14 can maintain linear motion during movement to avoid deviation or jamming.
[0038] In order to facilitate repair and maintenance, the upper shell 12 is also designed with a detachable upper cover 13. The upper cover 13 protrudes upward in the moving direction of the valve stem 14 to form a clearance cavity 131. The clearance cavity 131 provides sufficient moving space for the valve stem 14 to ensure that the valve stem 14 can be opened and closed smoothly. At the same time, the detachable design also allows users to easily check and replace internal components, thereby improving the service life and reliability of the product.
[0039] In this embodiment, we specially selected a 3-inch caliber valve body to adapt to different flushing needs. Compared with the conventional 3-inch caliber valve body, the valve body we designed is optimized in height, and its height range is precisely set between 12.0-13.0 cm. This design makes the overall size of the valve body more compact, especially in terms of height, which is significantly lower than the usual 3-inch caliber valve body. This low-height design is not only easy to install in toilets with low-level water tanks, but also helps to improve the aesthetics and comfort of the overall bathroom space. By precisely controlling the height of the valve body, we ensure that the performance of the drain valve is not affected while maximizing space utilization.
[0040] Key References Figure 4 , the upper end of the valve stem 14 is located in the inner cavity of the upper shell 12, and the upper end of the valve stem 14 is connected to the first swing rod 6 and the second swing rod 7, which are respectively used to connect to the external control switch to realize the control of the valve stem 14. Specifically, the foot-kick-type pull switch 2 is connected to the first swing rod 6 through the first traction rope 4. When the user kicks the switch with his foot, the first traction rope 4 will pull the first swing rod 6, and then pull the valve stem 14. Similarly, the hand-pressed pull switch 3 is connected to the second swing rod 7 through the second traction rope 5. When the user presses the switch, the second traction rope 5 will pull the second swing rod 7, and the effect of lifting the valve stem 14 is also achieved. These two pull switches can be used separately, or they can be operated simultaneously according to the needs of the user to flexibly control the lifting and lowering of the valve stem 14.
[0041] Key References Figure 4 , the lower end of the valve stem 14 passes through the guide channel 121 at the bottom of the upper shell 12 and extends to the inside of the base 11. This guide channel 121 ensures the stability and accuracy of the valve stem 14 during the lifting process. When the valve stem 14 moves under the action of the pull switch, the water stop 15 connected to its lower end will move with the movement of the valve stem 14. The function of the water stop 15 is to open or block the drain port 112 on the base 11. When the water stop 15 leaves the drain port 112, water can flow out smoothly to achieve the flushing function; and when the water stop 15 tightly blocks the drain port 112, water is prevented from flowing out, and the drain valve is in a closed state. Through such a design, the user can easily control the opening and closing of the drain valve, thereby realizing the flushing control of the toilet.
[0042] Regarding the connection method between the water stop 15 and the valve stem 14, the utility model adopts a snap-fit design between the plug connector 151 and the plug socket 142. Figure 3 As shown, the upper end of the water stop 15 is provided with a plug connector 151, and the lower end of the valve stem 14 is provided with a socket 142. Through the snap fit of the plug connector 151 and the socket 142, the water stop 15 can be firmly connected to the valve stem 14, ensuring that the water stop 15 can move synchronously when the valve stem 14 is raised or lowered, and effectively controlling the opening and closing of the drain port 112. This connection method is not only simple in structure and easy to install, but also has high connection strength and stability, and can meet the requirements of long-term use. In this embodiment, Fig. 9 As shown, the water stop member 15 is composed of an upper water sealing cover 152 , a silicone water stop pad 153 and a lower water sealing cover 154 , wherein the silicone water stop pad 153 is used to seal the drain outlet 112 , and the upper and lower water sealing covers are used to fix the water stop pad 153 and then connected to the valve stem 14 .
[0043] Key References Figure 3 and Figure 5 , the rotating shafts of the first swing rod 6 and the second swing rod 7 are coaxially arranged, which means that they share the same rotation center, and the two swing rods are pivoted together in the inner cavity of the upper shell 12, and through this pivot point, the swing rod can rotate around the rotating shaft. The active end of the first swing rod 6 is connected to the first traction rope 4. When the kick-type pull switch 2 is triggered, the first traction rope 4 will pull the active end of the first swing rod 6, so that the first swing rod 6 rotates around the rotating shaft. The driven end of the first swing rod 6 is connected to the valve stem 14. As the first swing rod 6 rotates, the driven end will push or pull the valve stem 14 to make it move accordingly. Similarly, the active end of the second swing rod 7 is connected to the second traction rope 5. When the hand-pressed pull switch 3 is pressed, the second traction rope 5 will pull the active end of the second swing rod 7 to make it rotate around the rotating shaft. The driven end of the second swing rod 7 is also connected to the valve stem 14. As the second swing rod 7 rotates, the driven end will cooperate with the action of the first swing rod 6 to jointly control the movement of the valve stem 14. Through this design, the first swing rod 6 and the second swing rod 7 can be triggered by the pull switch separately or simultaneously, thereby realizing flexible control of the valve stem 14. Whether by kicking or pressing, the opening and closing of the drain valve can be effectively controlled, providing a convenient use experience for users.
[0044] As a further improvement of the structure, Figure 3 and Figure 5As shown, a rectangular lifting groove 143 is designed at the upper end of the valve stem 14, and the groove extends along the length direction of the valve stem 14 to form a stable track. The driven ends of the first rocker arm 6 and the second rocker arm 7 are movably arranged in this rectangular lifting groove 143. The main function of the rectangular lifting groove 143 is to provide sufficient clearance space for the rocker arm to ensure that the valve stem 14 can be smoothly lifted or released when the rocker arm swings. When one of the two lifting switches is activated (whether it is a foot-kick type or a hand-press type), the rocker arm connected to it will rotate around the rotating shaft and move in the rectangular lifting groove 143, thereby lifting the valve stem 14. At the same time, the rocker arm connected to the other unactivated lifting switch will remain stationary (such as Figure 6 and Figure 7 As shown in the figure, the rectangular pull-up groove 143 may be located at the lower part of the rectangular pull-up groove 143 without any interference. This design allows the two pull-up switches to work independently while ensuring that their movements do not interfere with each other. No matter which method the user chooses to use to control the drain valve, efficient and stable flushing operation can be achieved. In addition, the introduction of the rectangular pull-up groove 143 also enhances the connection stability between the valve stem 14 and the rocker arm, and improves the durability and reliability of the drain valve.
[0045] like Figures 3 to 5 As shown, a float 16 is provided in the inner cavity of the upper shell 12, and the float 16 is a full-row float 16. Both sides of the float 16 are pivotally connected to the side walls of the inner cavity, so that the float 16 can float up and down flexibly when the water level changes. When the kick-type or hand-pressed pull switch 3 is triggered, the control valve stem 14 is lifted, and the water level will rise accordingly. In this process, the end of the float 16 farther from the pivot point will be lifted upward, and at the same time, the hook 141 on the valve stem 14 will move to the top of the float 16 hanging platform 161 as the valve stem 14 is lifted. At this time, if the user releases the switch button, the hook 141 will automatically hang on the hanging platform 161, thus forming a temporary locking state. Due to the buoyancy of the float 16, after the hook 141 is hung on the hanging platform 161, the falling speed of the valve stem 14 will be delayed, and then the falling of the water stop 15 will be delayed, ensuring that the drain port 112 remains open for a period of time, realizing the function of full drainage. As the water level gradually drops, the buoy 16 will also fall accordingly. When the buoy 16 drops to a certain position, the hook 141 will be separated from the hanging platform 161, and the buoyancy support of the buoy 16 will be lost. At this time, the valve stem 14 begins to fall under its own gravity or the action of an external mechanism, driving the water stop 15 to re-block the drain port 112. This process ensures that the drain valve can be closed in time after the water level drops, avoiding unnecessary water loss.
[0046] Key References Figure 1 and Figure 7The foot-kick pull switch 2 includes a first control box 21, a first button 22 and a first swing rod 23. The first swing rod 23 is fixed in the first control box 21 through a pivot point to ensure that it can swing freely. The active end of the first swing rod 23 contacts the first button 22, and the driven end of the first swing rod 23 is connected to the first pull rope. When the user kicks the first button 22 with his foot, the pressure of the button will be transmitted to the active end of the first swing rod 23. As the active end is subjected to force, the first swing rod 23 will swing from the pivot point, and its driven end will move accordingly, thereby pulling the first traction rope 4 connected to it. In this way, the opening of the drain valve can be controlled by a simple kicking action.
[0047] The hand-pressed pull switch 3 includes a second control box, a second button, and a second swinging rod, and the second swinging rod is also fixed in the second control box through a pivot point. The active end of the second swinging rod contacts the second button, and the driven end of the second swinging rod is connected to the second pulling rope. When the user presses the second button, the active end of the second swinging rod is subjected to force, so that the driven end of the second swinging rod swings around the pivot point, pulling the second pulling rope 5 connected thereto. In this way, the user can control the opening of the drain valve by hand pressing operation.
[0048] It is worth noting that the foot-kick pull switch 2 and the hand-press pull switch 3 are similar in function, but their structure and operation mode can be designed according to actual needs. They can be completely the same mechanical push switch structure to adapt to different installation environments and user habits; or they can be mechanical push switch structures with different structures to meet specific design needs and aesthetic requirements. This flexibility makes the drain valve of the utility model more advantageous in terms of applicability and user experience.
[0049] The traction rope of the utility model adopts a design in which an outer jacket wraps an inner steel wire rope to ensure sufficient strength and durability. However, it should be noted that the traction rope is not limited to this specific rope structure. In practical applications, other suitable rope structures can be selected according to specific use environments and requirements to achieve the functions of the traction rope.
[0050] like Figure 1 As shown, in order to enhance the safety and reliability of the drain valve, an overflow channel 17 is set on the side of the base 11, and an overflow pipe 18 is inserted in the overflow channel 17. When the water entering the water tank is too high, it will overflow into the pipe. At the same time, a pipe cover 19 is provided at the upper end of the overflow pipe 18, and the small hole 20 on the pipe cover 19 is used to insert a water inlet and replenishment pipe (not shown in the figure).
