Detailed Description

The utility model will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model provides a double-mode wire-control ultralow drainage valve, which is shown in figures 1 to 9, and comprises an ultralow flushing mechanism 1, a foot-operated lifting switch 2, a hand-operated lifting switch 3, a first traction rope 4 and a second traction rope 5, wherein the ultralow flushing mechanism 1 is respectively connected with the foot-operated lifting switch and the hand-operated lifting switch through two traction ropes, and can independently or jointly control the opening and closing of a valve body to realize double-mode mechanical control.

The ultra-low flush mechanism 1 is compact and particularly suitable for low tank toilets, and as shown in fig. 1 to 3, comprises a valve body and a valve stem 14 movably arranged in the valve body, and in particular, the valve body comprises a base 11 and an upper housing 12. Wherein, the circumference side of the base 11 is provided with a water inlet 111, and a water outlet 112 is positioned at the bottom of the base 11. The upper casing 12 is disposed on the upper portion of the base 11, and has an inner cavity therein, and a guide channel 121 is formed at the bottom of the inner cavity, and is used for the valve rod 14 to pass through, so as to ensure that the valve rod 14 can keep rectilinear motion during the moving process, and avoid offset or jamming.

For easy maintenance, the upper housing 12 is also provided with a removable upper cover 13. This upper cover 13 protrudes upward in the direction of movement of the valve stem 14, forming a relief cavity 131. This relief cavity 131 provides sufficient space for the valve stem 14 to move, ensuring that the valve stem 14 is smooth during opening and closing. Meanwhile, the detachable design also enables a user to conveniently check and replace the internal parts, so that the service life and the reliability of the product are improved.

In this embodiment, a3 inch diameter valve body is particularly preferred to accommodate different flush demands. Compared with the conventional 3-inch bore valve body, the valve body designed by us is optimized in height, and the height range is accurately set between 12.0 cm and 13.0 cm. This design results in a more compact overall size valve body, particularly in terms of height, significantly below the typical 3 inch bore valve body. The low-height design is not only convenient to install in the closestool of the low-level water tank, but also helps to improve the aesthetic degree and the use comfort of the whole 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.

Referring to fig. 4 with emphasis, the upper end of the valve rod 14 is located in the inner cavity of the upper housing 12, and the upper end of the valve rod 14 is connected with a first swing rod 6 and a second swing rod 7, which are respectively used for connecting an external control switch to realize the control of the valve rod 14. Specifically, the kick-type lifting switch 2 is connected with the first swing rod 6 through the first traction rope 4, and when a user kicks the switch with a foot, the first traction rope 4 pulls the first swing rod 6, so that the valve rod 14 is lifted. Similarly, the hand-push type lifting switch 3 is connected with the second swing rod 7 through the second traction rope 5, and when a user presses the switch, the second traction rope 5 pulls the second swing rod 7, so that the effect of lifting the valve rod 14 is achieved. The two lifting switches can be used independently, and can be operated simultaneously according to the needs of users so as to flexibly control the lifting of the valve rod 14.

Referring to fig. 4 with emphasis, the lower end of the valve stem 14 extends into the base 11 through a guide passage 121 at the bottom of the upper housing 12. This guide channel 121 ensures stability and accuracy of the valve stem 14 during lifting and lowering. When the valve stem 14 is moved by the pull-up switch, the water stop 15 connected to the lower end thereof moves following the movement of the valve stem 14. The water stop 15 functions to open or close the drain 112 in the base 11. When the water stop member 15 leaves the water outlet 112, water can smoothly flow out to realize the flushing function, and when the water stop member 15 tightly seals the water outlet 112, water is prevented from flowing out, and the water discharge valve is in a closed state. Through the design, a user can conveniently control the opening and closing of the drain valve, so that the flushing control of the toilet is realized.

Regarding the connection mode of the water stop 15 and the valve rod 14, the utility model adopts the snap fit design of the plug 151 and the socket 142. As shown in fig. 3, the upper end of the water stop 15 is provided with a plug 151, and the lower end of the valve stem 14 is provided with a plug seat 142. By the snap fit of the plug 151 and the socket 142, the water stop 15 can be firmly connected to the valve stem 14, so that the water stop 15 can move synchronously when the valve stem 14 is lifted, and the opening and closing of the drain outlet 112 can be effectively controlled. The connecting mode is simple in structure, convenient to install, high in connecting strength and stability and capable of meeting long-term use requirements. In this embodiment, as shown in fig. 9, the water stop member 15 is composed of an upper water stop cover 152, a water stop pad 153 made of silica gel, and a lower water stop cover 154, wherein the water stop pad 153 made of silica gel is used for blocking the water outlet 112, and the upper and lower water stop covers are used for fixing the water stop pad 153 and are connected to the valve stem 14.

With particular reference to fig. 3 and 5, the axes of rotation of the first and second pendulum rods 6, 7 are coaxially arranged, which means that they share the same center of rotation, and the two pendulum rods are jointly pivoted in the interior of the upper housing 12, through which point the pendulum rods can perform a rotational movement about the axes of rotation. The driving end of the first swing rod 6 is connected with the first traction rope 4, and when the kick-type lifting switch 2 is triggered, the first traction rope 4 pulls the driving end of the first swing rod 6, so that the first swing rod 6 rotates around a rotating shaft. The driven end of the first swing rod 6 is connected with the valve rod 14, and the driven end pushes or pulls the valve rod 14 along with the rotation of the first swing rod 6, so that the valve rod 14 moves correspondingly. Likewise, the driving end of the second swing rod 7 is connected with the second traction rope 5, and when the hand-push type lifting switch 3 is pressed down, the second traction rope 5 pulls the driving end of the second swing rod 7 to rotate around the rotating shaft. The driven end of the second swing rod 7 is also connected with the valve rod 14, and the driven end cooperates with the action of the first swing rod 6 to control the movement of the valve rod 14 together with the rotation of the second swing rod 7. By means of this design, the first swing link 6 and the second swing link 7 can be triggered by pulling apart the levers respectively or simultaneously, so that flexible control of the valve rod 14 is achieved. Whether the water draining valve is kicked or pressed by hands, the water draining valve can be effectively controlled to be opened and closed, and convenient use experience is provided for users.

As a further improvement in construction, as shown in fig. 3 and 5, the upper end of the valve stem 14 is provided with a rectangular pulling groove 143 extending along the length of the valve stem 14 to form a stable track. The driven ends of the first swing rod 6 and the second swing rod 7 are movably arranged in the rectangular lifting groove 143. The rectangular lifting groove 143 has the main function of providing sufficient abdication space for the swing link and ensuring that the valve rod 14 can be smoothly lifted or released when the swing link swings. When one of the two pull switches is activated (either kick or hand-operated), the rocker to which it is attached rotates about the shaft and moves within the rectangular pull slot 143, thereby pulling the valve stem 14. At the same time, the rocker to which the other, unactuated pull-up switch is connected will remain stationary (as shown in fig. 6 and 7) and may be located in the lower portion of the rectangular pull-up slot 143 without any interference. This design allows the two lift pulls to work independently while ensuring that the movements between them do not interfere with each other. No matter which mode is selected by a user to control the drain valve, the efficient and stable flushing operation can be realized. In addition, the introduction of the rectangular pulling groove 143 also enhances the connection stability between the valve stem 14 and the swing link, improving the durability and reliability of the drain valve.

As shown in fig. 3 to 5, the pontoon 16 is disposed in the inner cavity of the upper casing 12, the pontoon 16 is a full-row pontoon 16, and two sides of the pontoon 16 are pivotally connected to the side walls of the inner cavity, so that the pontoon 16 can flexibly float up and down when the water level changes. When the kick or push type pull switch 3 is triggered, the water level rises as the control valve stem 14 is lifted. In this process, the end of the pontoon 16 that is farther from the pivot is lifted upward, and at the same time, the hook 141 on the valve stem 14 moves above the hanging table 161 of the pontoon 16 as the valve stem 14 is lifted. At this time, if the user releases the switch button, the hanger 141 is automatically hung on the hanging stand 161, thus forming a temporary locking state. Due to the buoyancy of the pontoon 16, the hook 141 is hung on the hanging table 161 to delay the falling speed of the valve rod 14, further delay the falling of the water stop 15, ensure that the water outlet 112 is kept in an open state for a period of time, and realize the function of full water drainage. As the water level gradually drops, the pontoon 16 will drop accordingly. When the pontoon 16 falls to a certain position, the hanger 141 is disengaged from the hanger 161, and the buoyancy support of the pontoon 16 is lost. At this time, the valve stem 14 begins to fall under the action of its own weight or an external mechanism, and drives the water stopper 15 to reseat 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.

With particular reference to fig. 1 and 7, the kick-type lift switch 2 comprises a first control box 21, a first button 22 and a first swinging rod 23, wherein the first swinging rod 23 is fixed in the first control box 21 through a pivot point, so as to ensure free swinging. The driving end of the first swing lever 23 is in contact with the first button 22, and the driven end of the first swing lever 23 is connected with the first pulling rope. When the user kicks the first button 22 with his foot, the pressure of the button is transmitted to the driving end of the first swing lever 23. With the force applied to the driving end, the first swinging rod 23 swings from the pivot joint, and the driven end moves along with the first swinging rod, so that the first traction rope 4 connected with the first swinging rod is pulled. Thus, the opening of the drain valve can be controlled by simple kicking action.

The hand-push type lifting and pulling device 3 comprises a second control box, a second button and a second swinging rod, and the second swinging rod is fixed in the second control box through a pivot joint. The driving end of the second swinging rod is contacted with the second button, and the driven end of the second swinging rod is connected with the second traction rope. When the user presses the second button, the driving end of the second swinging rod is stressed, so that the driven end swings around the pivoting position, and the second traction rope 5 connected with the driving end of the second swinging rod is pulled. In this way, the user can control the opening of the drain valve by the hand pressing operation.

It is noted that the kick-type pull-up switch 2 and the hand-push type pull-up switch 3 are functionally similar, but their structures and operation manners may be designed according to actual needs. The mechanical push switch can be of identical mechanical push switch structures so as to adapt to different installation environments and user habits, and can also be of different mechanical push switch structures so as to meet specific design requirements and aesthetic requirements. This flexibility makes the drain valve of the present utility model more advantageous in terms of applicability and user experience.

The traction rope adopts the design that the outer sleeve wraps the inner steel wire rope, so that the sufficient strength and durability are ensured. It should be noted that the traction ropes are not limited to this particular rope configuration. In practical application, other suitable rope structures can be selected according to specific use environments and requirements to realize the function of the traction rope.

As shown in fig. 1, in order to enhance the safety and reliability of the drain valve, an overflow channel 17 is provided at the side of the base 11, an overflow pipe 18 is inserted into the overflow channel 17, water entering the water tank overflows into the pipe when the water is too high, and a pipe cover 19 is provided at the upper end of the overflow pipe 18, and small holes 20 on the pipe cover 19 are used for inserting a water inlet and water supply pipe (not shown in the figure).
