[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] It should be noted that in the present invention, the terms "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element of the present invention must have a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0031] Cooperate Figures 1 to 5 As shown, the utility model discloses a dual-drive drain valve, which is installed in a toilet tank. The drain valve is driven to work by a dual-drive mode, which can be flexibly selected during use, and when one of the drive modes fails, the other drive mode can be selected to drive, thereby preventing the drain valve from failing to work.

[0032] A double-drive drain valve, comprising:

[0033] The valve body 10 is installed at the drain port of the water tank, and the valve body 10 is provided with a sealing member 11 for opening and closing the drain port.

[0034] A connecting assembly 20 is connected to the sealing member 11, and the connecting assembly 20 includes a lifting arm 21,

[0035] The driving assembly 30 includes a button 31 and a lifting member 32. The button 31 is connected to the lifting arm 21 through a connecting rod assembly 40. The lifting member 32 is connected to the lifting arm 21. Pressing the button 31 or pulling the lifting member 32 drives the lifting arm 21 and the sealing member 11 to rise and open the drain outlet.

[0036] The drain valve is installed at the drain outlet of the toilet water tank. The valve body 10 (the base of the valve body 10 is not shown in the figure) has a seal 11 adapted to the drain outlet. When the seal 11 seals the drain outlet, the toilet does not drain. The seal 11 detaches and opens the drain outlet. The water in the water tank is discharged through the drain outlet, and the toilet drains.

[0037] A connecting assembly 20 and a driving assembly 30 are arranged in the valve body 10. The connecting assembly 20 is used to connect the driving assembly 30 and the sealing member 11, so that the driving assembly 30 can connect and drive the sealing member 11 to move and open the drain port. Among them, the connecting assembly 20 includes a lifting arm 21, which is specifically connected to the driving assembly 30. The driving assembly 30 includes a button 31 and a lifting member 32. The button 31 is the drain button 31 of the drain valve, including a full-row button 31 and a half-row button 31. The button 31 is connected to the lifting arm 21 through a connecting rod assembly 40. Pressing the button 31 can drive the sealing member 11 to rise through the lifting arm 21, thereby opening the drain port for drainage. This is one of the driving modes of the drain valve. The lifting member 32 is connected to the lifting arm 21. By pulling the lifting member 32, the sealing member 11 can be driven to rise through the lifting arm 21, thereby opening the drain port for drainage. This is another driving mode of the drain valve.

[0038] The drain valve has two driving modes at the same time. Consumers can flexibly choose according to their needs when using it. At the same time, the two driving modes can be used as backup for each other. When one driving mode fails, the other driving mode can be used to avoid the drain valve being unable to open the drain outlet to drain water.

[0039] Cooperate Figures 2 to 5 As shown, the connection assembly 20 also includes a connection member 22, the top end of which is connected to the lifting arm 21, and the bottom end is connected to the sealing member 11. The lifting arm 21 drives the sealing member 11 to move up and down through the connection member 22. The connection member 22 is a lifting tube, and is a vertically extending hollow tube. The connection member 22 reduces weight and saves materials, and is also easy to assemble.

[0040] The top side wall of the connecting member 22 is provided with a slot 221, and the bottom end of the lifting arm 21 is provided with an elastic hook 211 corresponding to the slot 221. The elastic hook 211 is inserted into the connecting tube and engages with the slot 221. An elastic hook 211 is extended from the bottom end of one side of the lifting arm 21. After the elastic hook 211 is inserted into the connecting tube, it engages with the slot 221 to achieve assembly and fixation of the lifting arm 21 and the connecting member 22.

[0041] Cooperate Figures 2 to 3As shown, the connecting rod assembly 40 includes a rocker rod 41 and a connecting rod 42. The rocker rod 41 is rotatably connected to the valve body 10, and the rocker rod 41 is connected to the lifting arm 21 through the connecting rod 42. Pressing the button 31 drives the rocker rod 41 to swing and drives the lifting arm 21 and the sealing member 11 to rise through the connecting rod 42.

[0042] Specifically, the middle part of the swing rod 41 is rotatably connected to the valve body 10, one end of the swing rod 41 abuts against the lower end of the button 31, and the other end is rotatably connected to the top end of the connecting rod 42, and the bottom end of the connecting rod 42 is connected to the lifting arm 21. When the button 31 is pressed, the swing rod 41 abuts against one end below the button 31 and rotates downward, while the other end rotates upward, thereby driving the connecting rod 42, the lifting arm 21, the connecting member 22 and the sealing member 11 to rise together, thereby opening the drain port for drainage. When the force of pressing the button 31 is removed, each component is reset under the action of gravity, and the sealing member 11 is reset to seal the drain port.

[0043] Cooperate Figure 2 , Figure 4 As shown, in this embodiment, the lifting member 32 is a steel wire rope or a chain. Specifically, the valve body 10 is provided with a clearance hole 12, one end of the lifting member 32 is connected to the lifting arm 21, and the other end passes through the clearance hole 12 and extends to the outside of the valve body 10. The clearance hole 12 is provided at the top of the drain valve, the bottom end of the steel wire rope or chain is connected to the lifting arm 21, and the top end passes through the clearance hole 12 and extends to the outside of the drain valve, so as to facilitate pulling the steel wire rope or chain.

[0044] Specifically, the lifting arm 21 has an extension portion extending horizontally, and the extension portion is provided with a first connection portion 212 and a second connection portion 213 in sequence along the extension direction, the first connection portion 212 is connected to the connecting rod assembly 40, and the lifting member 32 is connected to the second connection portion 213. On the basis of the existing structure driven by the button 31, the extension portion is horizontally extended by the lifting arm 21, so that it can be connected to the lifting member 32, and the structural design is compact and ingenious.

[0045] A accommodating chamber 13 protruding outward is provided on one side of the valve body 10, and the valve body 10 has a hollow inner cavity, and the connecting component 20, the driving component 30, etc. are all assembled in the inner cavity. On the basis of the inner cavity, another accommodating chamber 13 connected thereto is provided to facilitate the setting of a lifting member 32, and the second connecting portion 213 is located in the accommodating chamber 13, and a clearance hole 12 is provided at the top of the accommodating chamber 13, one end of the lifting member 32 passes through the clearance hole 12 to be connected with the second connecting portion 213, and the other end passes through the clearance hole 12 to extend to the outside of the accommodating chamber 13.

[0046] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
