[0042] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with its embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] In the present invention, “first” and “second” do not represent specific numbers and orders, but are only used to distinguish names.

[0046] On the one hand, if Figure 1 and Figure 2 As shown, a sealed drainage mechanism in one embodiment of the present invention is arranged in the drainage cavity of aluminum alloy doors and windows, and includes a float member 1, a mounting plate 2 and a sealing plate 4; the float member 1 includes a float body 11, a hinged portion 12 and a connecting portion 13, the density of the float body 11 is less than the density of rainwater, the hinged portion 12 is rotatably connected to the mounting plate 2, and the connecting portion 13 is connected to the sealing plate 4; the sealing plate 4 includes a plate body 41 and a lifting guide rod 42 connected to the connecting portion 13, the plate body 41 can move along the hole direction of the drainage hole and is arranged on the outside of the drainage cavity, and the sealing plate 4 switches the sealing state and the conductive state of the drainage hole according to the buoyancy of the rainwater in the drainage cavity on the float body 11.

[0047] The above-mentioned sealed drainage mechanism utilizes the gravity and buoyancy principle of rainwater in the drainage cavity, and cooperates with the gravity of the float 1 to make the sealing plate 4 rise and fall, thereby switching the sealing state and the conductive state of the drainage hole; the rainwater in the drainage cavity is quickly discharged outdoors, and the drainage cavity can be kept closed when there is no rainwater, thereby achieving the triple functions of watertightness, airtightness, and mosquito-proofing; at the same time, the sealed drainage mechanism does not require any external power to operate, which is energy-saving and environmentally friendly.

[0048] In one embodiment, the mounting plate 2 is provided with an inverted U-shaped guide member 21, whose two vertical sides form a guide track 22. A lifting guide rod 42 is an L-shaped bent structure with a connecting end 43, which is disposed within the guide track 22 of the guide member 21. Thus, the inverted U-shaped guide member 21 forms the guide track 22, allowing the lifting guide rod 42 to move the plate 41 upward and downward along the drain hole, ensuring that the plate 41 effectively seals the drain hole.

[0049] In one embodiment, the hinged portion 12 of the float member 1 is a rotating shaft, and the connecting portion 13 is a sliding ring welded to both ends of the rotating shaft. The connecting end 43 is positioned within the elongated connecting hole of the sliding ring. Inserting the connecting end 43 into the elongated connecting hole of the sliding ring facilitates the vertical displacement vector of the connecting end 43 to change during the rotation of the float member 1, thereby switching the drainage hole between a sealed state and a conductive state by utilizing the buoyancy of the rainwater in the drainage chamber on the float body 11.

[0050] In one embodiment, a sealing strip 411 is provided on one side of the plate 41 adjacent to the aluminum alloy door or window. Specifically, the sealing strip 411 is annular and surrounds the edge of the plate 41. Thus, by providing the sealing strip 411 on the plate 41, the sealing strip 411 cushions deformation during the sealing contact between the plate 41 and the aluminum alloy door or window, preventing the plate 41 from making hard contact with the aluminum alloy door or window as it moves upward and downward along the drain hole, thereby enhancing the sealing effect.

[0051] In one embodiment, the sealing and drainage mechanism 6 includes a top switch 7 and a reset switch 8 .

[0052] On the one hand, if Figure 4 and Figure 5 As shown, an aluminum alloy door and window according to one embodiment of the present invention includes a mounting frame 5 and a sealing drainage mechanism 6. The mounting frame 5 includes a frame 51 and an isobaric adhesive strip 52 disposed on the frame 51. The frame 51 and the isobaric adhesive strip 52 form a drainage cavity 501. The frame 51 is provided with a drainage hole 502 communicating with the drainage cavity 501, and the sealing plate 4 of the sealing drainage mechanism 6 is adapted to fit within the drainage hole 502. In this manner, the sealing drainage mechanism 6 rapidly drains rainwater from the drainage cavity 501 to the outside, and can also maintain the drainage cavity 501 sealed in the absence of rain, thereby achieving the triple functions of watertightness, airtightness, and mosquito protection. Furthermore, the sealing drainage mechanism operates without requiring any external power, thus being energy-efficient and environmentally friendly.

[0053] Specifically, the sealing state of the drain hole 502 is as follows: Figure 3 As shown, at this time, there is no rainwater in the drainage cavity 501, and the gravity force F1 of the float member 1 is greater than the gravity force F2 of the sealing plate 4. Since F1>F2, the drainage hole 502 is in a closed state at this time, the air tightness is effectively improved, and the external rainwater is effectively prevented from entering the drainage cavity 501 of the aluminum alloy door and window with the help of external air pressure.

[0054] Specifically, the conduction state of the drain hole 502 is as follows: Figure 4 As shown, a large amount of rainwater seeps into the drainage cavity 501. The rainwater is blocked by the sealed isobaric strip 52 and cannot leak out of the mounting frame 5. The combined force F1 of the gravity of the float 1 and the buoyancy F 浮 The sum is less than the combined force F2 of the sealing plate 4 and the gravity F of part of the rainwater. 水 The sum of F1-F 浮 <F2+F 水 , the sealing plate 4 moves downward along the direction of the drainage hole 502. At this time, the aluminum alloy doors and windows are in a drainage state, so that the rainwater that has penetrated into the drainage cavity 501 can be quickly discharged to the outside. When all the water is discharged to the outside, F 浮 =0, F 水 =0, the gravity resultant force F1 of the float member 1 is greater than the gravity resultant force F2 of the sealing plate 4. Since F1>F2, the sealing plate 4 moves upward along the hole direction of the drainage hole 502, so that the drainage hole 502 is in a sealed state again.

[0055] like Figure 3 and Figure 6 、 Figure 7 、 Figure 8As shown, in one embodiment, a top switch 7 is further included on the frame 51 and is disposed at the top of the drainage cavity 501. The top switch 7 includes a cylindrical body 71 having a cavity therein, an expansion column 72 disposed in sequence within the cavity of the cylindrical body 71, and a top rod 73. The top rod 73 includes a rod body 731 and a top end 732, with the rod body 731 disposed within the cavity. After the expansion column 72 absorbs water and expands, it presses against the top rod 73 to move out of the cavity, and the top end 732 pushes the plate 41 of the sealing plate 4 away from the drainage hole. Rainwater often seeps into debris such as dust or leaves, which can cause the float 1 to become stuck and unable to rotate, thereby causing rainwater to accumulate in the drainage cavity 501. In this way, by using the top switch 7 set on the top of the drainage chamber 501, when too much rainwater accumulates in the drainage chamber 501, the expansion column 72 absorbs water and expands to press the top rod 73, causing the top rod 73 to push the sealing plate 4, forcing the drainage hole 502 to switch to the conductive state, thereby draining the rainwater in the drainage chamber 501.

[0056] In one embodiment, the cylinder 71 is fixedly mounted on the frame 51 by welding or fixing glue, thereby achieving fixed installation of the top switch 7.

[0057] In one embodiment, the cylinder 71 is provided with a water inlet 711 communicating with the cavity, and the water inlet 711 is disposed at the upper portion or top of the cylinder 71. Thus, by disposing the water inlet 711 at the upper portion or top of the cylinder 71, the position of the water inlet 711 defines a warning line for the amount of rainwater within the drainage cavity 501, thereby achieving forced drainage.

[0058] In one embodiment, the expansion column 72 is made of water-swellable rubber. Thus, the water-swellable rubber expands after absorbing water and returns to its original size after losing water, so that the expansion column 72 can be reused.

[0059] In one embodiment, a reset switch 8 is further included. A stopper 733 is provided on the top rod 73. The reset switch 8 is used to push the stopper 733, causing the top rod 73 to retract into the cavity. Thus, by pushing the stopper 733 against the reset switch 8, once the rainwater in the drainage cavity 501 is drained, the reset switch 8 can squeeze the expansion column 72 to remove water, accelerating its return to its original size.

[0060] In one embodiment, the reset switch 8 includes a swing lever 81 and an elastic connector 82. The swing lever 81 has a first hinged portion 811, a top connection portion 812, and a second hinged portion 813 disposed between the first hinged portion 811 and the top connection portion 812. The first hinged portion 811 is fixedly connected to the frame 51. The elastic connector 82 has a fixed end 821 and a hinged end 822. The fixed end 821 is fixedly connected to the frame 51, and the hinged end 822 is hingedly connected to the second hinged portion 813. Specifically, the elastic connector 82 is a spring. The elastic restoring force of the elastic connector 82 causes the top connection portion 812 of the swing lever 81 to press the top rod 73 upward, squeezing the expansion column 72 to dehydrate it and accelerating its return to its original size. In one embodiment, the limiting portion 733 is a bending frame, and the top connection portion 812 is a roller adapted to the bending frame. Specifically, the roller is provided with a rubber layer. In this way, the friction force is increased by the roller provided with the rubber layer, so that the force exerted by the roller on the bending frame is stable, which facilitates long-term resetting and extrusion.

[0061] In one embodiment, an aluminum alloy door and window includes a door leaf 9 that is movable relative to a mounting frame 5. The door leaf 9 includes a first frame 91, a second frame 92, and a connecting strip 93 connecting the first and second frames 91 and 92. The frame 51 is provided with a sealing strip 53 adapted to fit the second frame 92. When the sealing strip 53 is placed on top of the door leaf 9, the second frame 92, the sealing strip 53, the connecting strip 93, the isobaric strip 52, and the frame 51 form a sealed cavity. This sealed contact between the sealing strip 53 and the second frame 92 prevents rainwater from flowing into the sealed cavity through the gap between the door leaf 9 and the mounting frame 5 when the door leaf 9 is closed.

[0062] In one embodiment, a rainwater detector and an electric telescopic rod electrically connected to the rainwater detector are provided on the top of the drainage chamber 501. When the rainwater detector detects that too much rainwater has accumulated, the electric telescopic rod is controlled to push the sealing plate 4, forcing the drainage hole 502 to switch to a conductive state, thereby draining the rainwater in the drainage chamber 501.

[0063] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
