It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0022] like Figure 1-Figure 4As shown, a specific embodiment of the present invention provides an aluminum alloy thermal break sliding window, including a window frame 100 and a window sash 200, wherein the window frame 100 includes a thermal break bottom beam 1 and a ventilation cavity 2 located at the bottom of the thermal break bottom beam 1; the window sash 200 can translate on the window frame 100; the outer wall of the ventilation cavity 2 is provided with an air inlet 21, and the inner wall is provided with an air outlet 22; a vertical partition 23 and a lifting partition 24 are also provided in the ventilation cavity 2, the vertical partition 23 is provided with a guide column 231, the lifting partition 24 is provided with a slide groove 241, the slide groove 241 is inserted into the guide column 231, the lifting partition 24 can be lifted and lowered relative to the vertical partition 23, and when the lifting partition 24 rises to a predetermined height, the ventilation cavity 2 can be divided into a left cavity 2a and a right cavity 2b that are independent of each other; when the lifting partition 24 descends, the left cavity 2a and the right cavity 2b can be connected.

[0023] A lifting transmission mechanism 3 is provided in the bottom beam 1 of the thermal break bridge, and the lifting transmission mechanism 3 is provided with a pressing head 31. When the window sash 200 moves to a predetermined position of the window frame 100, it can contact with the lifting transmission mechanism 3 to convert the translational motion of the window sash 200 into a descending motion of the pressing head 31. The pressing head 31 contacts with the lifting partition 24 to press the lifting partition 24 downward.

[0024] By adopting the above scheme, a ventilation cavity 2 is set under the traditional thermal insulation bottom beam 1, and air is taken in from the outside through the air inlet 21, and air is discharged to the indoor through the air outlet 22, so as to achieve continuous ventilation when the window sash 200 is closed, which not only ensures the sound insulation and heat insulation effect, but also can adjust the indoor temperature, save energy and reduce emissions, and improve user comfort. The ventilation cavity 2 is provided with a lifting partition 24, which can close the ventilation cavity 2 when needed, and the top of the lifting partition 24 corresponds to the position of the plastic thermal insulation bridge 11. By utilizing the elasticity of the plastic thermal insulation bridge 11, the sound insulation and sealing performance of the lifting partition 24 can be ensured when closed.

[0025] Preferably, the lifting transmission mechanism 3 includes a pulling head 32, a spring piece 33, a pulling slide 34, a swing gear 35 and a swing arm 36, the spring piece 33 is arranged at the bottom of the window sash 200 and extends obliquely downward; the pulling slide 34 is arranged on the inner side of the side wall of the broken bridge bottom beam 1, and a rack 321 is provided at the bottom of the pulling head 32, and can slide along the pulling slide 34; the swing gear 35 is provided with the swing arm 36, and the swing gear 35 is rotatably arranged in the broken bridge bottom beam 1 and meshed with the rack 321, and the pressing head 31 is arranged at the end of the swing arm 36.

[0026] Among them, the end of the pulling head 32 is connected to the return spring 37, and a pulling hook 322 is provided on the upper part, a first sliding column 323 is provided on the front part of both sides, and a second sliding column 324 is provided on the rear part. The first sliding column 323 and the second sliding column 324 are both arranged in the pulling slot 34; a downward-bending unhooking sliding section 341 is provided at the end of the pulling slot 34.

[0027] It should be noted that when the user opens the window, the window sash 200 moves relative to the window frame 100, and the spring piece 33 under the window sash 200 abuts against the pulling head 32, driving the pulling head 32 to move along the pulling slide 34. The pulling head 32 drives the swing gear 35 to rotate through the rack 321 at the bottom, and the swing arm 36 swings downward accordingly, and the pressing head 31 presses down the lifting partition 24. When the pulling head 32 reaches the unhooking slide section 341, it will move downward along the unhooking slide section 341, and the pulling head 32 will be unhooked from the spring piece 33. When the lifting partition 24 is pressed down to a predetermined position, it is locked, and the ventilation chamber 2 is opened. The pulling head 32 and the swing gear 35 are automatically reset under the action of the reset spring 37. When the user closes the window, the spring piece 33 contacts the pulling head 32 in the opposite direction, and the spring piece 33 is compressed by the pulling head 32 and directly passes over the pulling head 32. By adopting the above structure, the lifting partition 24 can be automatically opened when the user opens the window without the user's deliberate control. The usage habits are the same as those of ordinary sliding windows, and the ventilation effect can be retained when the user closes the window.

[0028] In order to ensure the locking of the lifting partition 24, a lock buckle 25 is provided on the lifting partition 24, and a lock block 26 is also provided in the broken bridge bottom beam 1. The lock block 26 is hinged to one side of the lock buckle 25 through a lock block hinge shaft 261; the side of the lock buckle 25 has a first inclined surface 251, and the top has a first locking plane 252. The top of the lock block 26 is provided with a second inclined surface 262, and the bottom is provided with a second locking plane 263. When the lifting partition 24 is pushed down, the first inclined surface 251 of the lock buckle 25 cooperates with the second inclined surface 262 of the lock block 26 to push the lock block 26 to rotate. When the lifting partition 24 is lowered into place, the first locking plane 252 is located at the bottom of the second locking plane 263, and the lock block 26 clamps and fixes the lock buckle 25.

[0029] Combination Figure 5 As shown, in order to realize the automatic closing function of the ventilation cavity 2 when it rains, a water guide groove 27 is provided in the left cavity 2a, the top of the water guide groove 27 is connected to the surface of the broken bridge bottom beam 1, the side is connected to the air inlet 21, and the rear surface is provided with an avoidance groove 271; a floating block 28 is provided in the water guide groove 27, and the floating block 28 is connected to a transmission rod 281, and the transmission rod 281 extends from the avoidance groove 271 and abuts against the left bottom of the locking block 26.

[0030] Preferably, the lower part of the water channel 27 is provided with a water storage space with four sides closed, and the transmission rod 281 is provided with a transmission rod hinge shaft 282, and the transmission rod 281 can swing around the transmission rod hinge shaft 282. When it rains, rainwater on the window sash 200 flows to the surface of the broken bridge bottom beam 1 and flows into the water channel 27. The accumulated water in the water channel 27 rises, so that the floating block 28 rises under the action of buoyancy. The floating block 28 no longer resists the bottom of the locking block 26 through its own weight and the lever action of the transmission rod 281. The locking block 26 is pushed to flip by the lock buckle 25, and the lifting partition 24 rises to a predetermined height under the action of the return spring 242 at the bottom, preventing heavy rain from entering the room from the ventilation cavity 2.

[0031] In order to simultaneously realize the high wind automatic closing function of the ventilation chamber 2, inclined wind plates 283 are provided on both sides of the floating block 28, the left wall of the water guide groove 27 is provided with a first wind pressure hole 284, and the right wall is provided with a second wind pressure hole 285, the first wind pressure hole 284 is provided below the wind plate 283, and the second wind pressure hole 285 is provided above the wind plate 283. When the wind pressure inside and outside the window frame 100 is too high (generally speaking, the outdoor wind pressure is greater than the indoor wind pressure), the airflow flows from the first wind pressure hole 284 to the second wind pressure hole 285. Since the first wind pressure hole 284 and the second wind pressure hole 285 are blocked by the wind plate 283, the wind plate 283 will be pushed up, that is, the floating block 28 will rise, achieving an effect similar to the buoyancy of rainwater. The floating block 28 no longer resists the bottom of the locking block 26 by its own weight and the leverage of the transmission rod 281. The locking block 26 is pushed to flip by the lock buckle 25, and the lifting partition 24 rises to a predetermined height under the action of the return spring 242 at the bottom, preventing strong wind from entering the room from the ventilation cavity 2.

[0032] In order to maximize the ventilation effect and improve the silent performance, the right cavity 2b is provided with a first silent dust-proof board 291 and a second silent dust-proof board 292. The first silent dust-proof board 291 is located on the left side, and its top is connected to the bottom surface of the broken bridge bottom beam 1 and is tilted to the lower right side; the bottom of the second silent dust-proof board 292 is connected to the bottom of the right cavity 2b and is arranged parallel to the first silent dust-proof board 291 at a predetermined gap. The first silent dust-proof board 291 and the second silent dust-proof board 292 can be made of sound-absorbing materials. The tilted first silent dust-proof board 291 and the second silent dust-proof board 292 can lengthen the propagation path of the sound and improve the sound absorption effect. The tilted suspended setting of the first silent dust-proof board 291 can also prevent small insects and some dust from entering the room from the ventilation cavity 2.

[0033] The air inlet 21 is a circular hole arranged in an array, and the air outlet 22 is a strip hole arranged in an array; a manual switch plate 20 is provided on one side of the inner wall, and the manual switch plate 20 can be manually raised and lowered, and the manual switch plate 20 is provided with matching holes 201 of the same shape and arrangement as the air outlet 22. The circular holes can effectively prevent insects and foreign objects from entering the ventilation cavity 2, and the strip holes can reduce wind resistance and improve ventilation efficiency. The manual switch plate 20 can be manually raised and lowered to open or close the air outlet 22, which acts as a manual master switch.

[0034] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
