Description

Technical Field

[0001] The invention relates to the technical field of sanitary ware, and in particular to a lever-type flushing button and a flushing water tank using the same. Background Art

[0002] The mechanical water pumping buttons of traditional bathroom water tanks are generally pressed vertically. The vertical press buttons are easy to cause inconvenience to users with long nails and easily cause nail breakage. The installation method of the water pumping buttons of bathroom water tanks is that the levers between the connecting rods are connected and the connecting rods are long. On the one hand, the overall structure of the button occupies too much volume of the water tank. On the other hand, the connection between the piston and the water outlet of the water tank is prone to insufficient sealing and water seepage. The traditional mechanical water pumping buttons require a lot of force when pressed, which is not friendly to female use. The water output is also uncontrollable, resulting in a waste of water resources. Summary of the invention

[0003] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a lever-type flush button which can realize the inclined lever-type pressing of the flush button and prevent pinching during use, thereby improving the safety of bathroom products and having a simple and practical structure.

[0004] According to a first aspect of the present invention, there is provided a lever-type flush button, comprising a shell, the shell being a trapezoidal shell, the narrow side of the shell being provided with a first connecting portion, the wide side being an arc-shaped baffle, a first round rod being provided in the shell, and the two ends of the first round rod being fixedly connected to the inner wall of the shell; a connecting rod assembly comprising a first connecting rod and a second connecting rod, the first connecting rod being an "I"-shaped connecting rod, the two ends of the first connecting rod being arc-shaped slots with notches, the width of the notch being L1, L1 being smaller than the inner diameter of the slot, and the slot at one end of the first connecting rod being hinged to the first round rod; the second connecting rod comprising a mounting portion and a second connecting portion, the mounting portion being a mounting ear, the mounting portion being provided with a second round rod, the two ends of the second round rod being fixedly connected to the two ends of the mounting ear, and the second round rod being hinged to the slot at one end of the first connecting rod.

[0005] A lever-type flush button of the present invention has at least the following beneficial effects: a first connecting portion is provided on the narrow side of the shell, and a first round rod is also provided in the shell, wherein the first round rod is connected to a slot at one end of the first connecting rod, and the slot at the other end of the first connecting rod is hinged to the mounting portion of the second connecting rod. The shell uses the connecting point of the first connecting portion and the water tank as a hinge point, and uses the connecting point of the first round rod and the first connecting rod as a movable fulcrum to realize the lever-type pressing of the flush button, and the wide side of the shell is provided with an arc-shaped baffle. Since the flush button moves in a fan shape when pressed, the arc-shaped baffle can always fit the water tank body during the pressing process, which can prevent the user's nails or fingers from being pinched, and help to improve the safety of the flush button. The second connecting portion of the second connecting rod is connected to the control valve of the water tank and is the supporting point of the flush button. The width L1 of the notch is smaller than the inner diameter of the slot, which can facilitate the hinge connection of the first round rod and the second round rod with the slot buckle, facilitate installation and disassembly, and has a simple and practical structure.

[0006] According to the lever-type flush button of the first aspect of the present invention, a panel is provided on the top of the shell, one end of the panel is an arc surface and is smoothly connected to the arc baffle of the shell, and the other end of the panel is an inclined surface and is smoothly connected to the narrow side of the shell. One end of the panel is an arc surface, and the other end is an inclined surface, which is beneficial to the appearance of the connection between the panel and the shell and the appearance of the flush button, and is also beneficial to the smoothness of the relative sliding of the flush button and the water tank body.

[0007] According to the lever-type flush button of the first aspect of the present invention, the notch edge of the slot is provided with a rounded corner, which facilitates the buckle connection between the first round rod and the slot, facilitates installation and disassembly, and has a simple and practical structure.

[0008] According to the lever-type flush button of the first aspect of the present invention, the second round rod and the mounting portion are manufactured in one piece, which can simplify the manufacturing process and help reduce production costs.

[0009] According to a second aspect of the present invention, there is provided a flush water tank using a lever-type flush button, wherein the flush button is embedded in a mounting opening at the top of the water tank, the panel is flush with the top of the water tank body when not in operation, the first connecting portion is hinged to the rear cover plate of the water tank body, the arc-shaped baffle is slidably connected to the front cover plate of the water tank, the water tank further comprises a control valve, and the second connecting portion is fixedly connected to the control valve.

The flushing button is hingedly mounted on the water tank by combining the mounting hole and the third round rod, and the structure is simple and practical.

[0013] According to the second aspect of the present invention, a flushing water tank is provided with a plurality of flushing buttons, which are arranged at intervals and connected in series in sequence through a third round rod. The flushing buttons are arranged at intervals and connected in series in sequence through a third round rod to simplify the connection design between the flushing buttons and the water tank, and the number of flushing buttons of the water tank can be designed according to functional requirements.

[0014] According to the second aspect of the present invention, a flushing water tank is provided with a notch at the connection between the front cover plate and the arc-shaped baffle plate of the water tank. The notch is used to match the pressing of the flush button, which can prevent the user's fingers from being pinched when pressing the flush button, thereby improving the safety performance of the product.

[0015] According to a flushing water tank of the second aspect of the present invention, the height of the notch is L2, and L2 is equal to the vertical height when the flush button is pressed down to the maximum value.
