Abstract
Description
Technical Field
[0001] This application relates to the field of building technology, and in particular to a ventilated wall structure. Background Technology
[0002] Indoor air quality has always been an important factor in building quality, as it is directly related to human health. Undoubtedly, the best way to improve indoor air quality is to open windows in buildings and make full and effective use of natural ventilation. Natural ventilation refers to the use of natural wind pressure difference and thermal pressure difference for ventilation and air exchange between indoor and outdoor air. Natural ventilation can improve indoor comfort without consuming energy, and compared with powered fans, it also has the advantages of being economical and noiseless.
[0003] To maintain good indoor air quality, people usually keep their windows open. However, when it suddenly rains while people are working outside, rainwater or moisture can enter the room through the open windows, causing bedding to become damp and items to get wet, thus affecting people's lives and reducing their comfort. Summary of the Invention
[0004] To improve people's living comfort, this application provides a ventilated wall structure.
[0005] The ventilated wall structure provided in this application adopts the following technical solution:
[0006] A ventilated wall structure includes a ventilation window, which includes a window frame and a rotatable window sash within the window frame. A fixing groove is provided within the window frame, and a fixing rod is fixedly installed within the fixing groove. The window sash rotates on the fixing rod. A first torsion spring is sleeved on the fixing rod, and the two ends of the first torsion spring are fixedly connected to the window sash and the inner wall of the fixing groove. A limiting component is provided within the window sash to limit its own movement. A rain collection groove is provided on the window, and a closing component for closing the window sash is provided within the rain collection groove.
[0007] By adopting the above technical solution, when people open the window, the limiting component can limit the window and fix the position of the window sash, reducing the possibility of the window sash rotating. When the window is open and it rains, the rainwater falls into the rain collection channel and drives the closing component to close the window sash, thereby reducing the entry of rainwater and moisture in the air into the room, thus reducing the possibility of indoor bedding and other items becoming damp and improving people's living comfort.
[0008] Preferably, the window sash has a storage slot, and the limiting component includes a first gear and a limiting block. The first gear is sleeved on and slides on the fixed rod. A connecting rod is fixedly connected in the storage slot. The limiting block rotates on the connecting rod. A second torsion spring is sleeved on the connecting rod. The two torsion arms of the second torsion spring are fixedly connected to the connecting rod and the limiting block, respectively. The limiting block can be inserted into the tooth groove of the first gear.
[0009] By adopting the above technical solution, when the window sash is rotated, the limiting block rotates along with the window sash. At this time, the first gear is fixed, and the limiting block rotates against the second torsion spring. When the limiting block moves away from the first gear, the limiting block is inserted into the next tooth groove of the first gear under the action of the second torsion spring until the window sash stops rotating. The limiting block is then inserted into the first gear under the action of the second torsion spring to fix the window sash.
[0010] Preferably, the rain collection trough is located at the top of the window sash, and the length of the rain collection trough is close to the width of the window sash. The inner wall of the rain collection trough is connected to a water inlet channel, which is connected to the storage trough.
[0011] By adopting the above technical solution, the longer length of the rainwater collection trough can improve the efficiency of rainwater collection, and the water inlet channel can transport the collected rainwater to the storage tank to activate the shut-off component.
[0012] Preferably, the closing component includes a sponge, a connecting block, and a first spring. The connecting block is fixedly sleeved on the fixed rod, and the two ends of the first spring are respectively fixedly connected to the connecting block and the first gear. A sliding groove is provided on the fixed rod, and a slider is fixedly connected to the inner wall of the first gear. The slider slides in the sliding groove, and the sponge is sleeved and slides on the fixed rod, abutting against the first gear.
[0013] By adopting the above technical solution, rainwater in the rain collection trough flows into the sponge through the water inlet channel. The sponge absorbs water and becomes heavier. When the sponge absorbs a certain amount of water, it pushes the first gear to move against the first spring. When the first gear moves away from the limit block, the limit of the window sash is released, and the window sash rotates to the closed state under the action of the first torsion spring, thereby closing the window sash.
[0014] Preferably, the window sash has a water outlet channel, one end of which is connected to the storage tank and the other end of which is connected to the outside. The storage tank is equipped with a squeezing component that can squeeze the sponge.
[0015] By adopting the above technical solution, after the rain stops, when people need to open the window again, they can squeeze the water out of the sponge through the squeezing component and let it flow out of the window through the water outlet channel, thereby reducing the weight of the sponge. In turn, the first gear can maintain its position under the action of the first spring, thus maintaining the limit of the window.
[0016] Preferably, the window sash has a placement groove, a plug slides in the placement groove, a second spring is provided in the placement groove, the two ends of the second spring are respectively fixedly connected to the plug and the inner wall of the placement groove, the plug has an inclined surface, the window frame has a slot for the plug to be inserted, and the window sash is provided with a drive assembly for driving the plug to move.
[0017] By adopting the above technical solution, when the window sash is closed, the inclined surface on the insert block abuts against the window frame, and the window frame pushes the insert block to compress the second spring. When the window sash is completely closed, the insert block is inserted into the slot under the action of the second spring, thereby strengthening the closing of the window sash and reducing the window sash from opening under the action of outside wind.
[0018] Preferably, the drive assembly includes a second gear, a rack, a handle, and a rotating rod. The handle rotates on the window sash, and the two ends of the rotating rod rotate on the opposite inner walls of the placement groove. The second gear is fixedly sleeved on the rotating rod and rotates within the placement groove. The rack slides within the placement groove, and one end of the rack is fixedly connected to the insert block. The second gear and the rack mesh with each other.
[0019] By adopting the above technical solution, when people need to open the window, they first turn the handle, which drives the second gear to rotate, which in turn drives the rack to rotate, which in turn drives the insert to move away from the slot. Then, people push the handle to open the window.
[0020] Preferably, the extrusion assembly includes an extrusion plate, a pressure rod, and a rotating rod. The extrusion plate is slidably fitted onto the fixed rod and abuts against the sponge. The rotating rod rotates on the inner wall of the storage tank. The pressure rod is fixedly fitted onto the rotating rod and abuts against the extrusion plate. A first rotating roller is fixedly fitted onto the rotating rod, and a second rotating roller is fixedly fitted onto the rotating rod. The first rotating roller and the second rotating roller are connected by a belt.
[0021] By adopting the above technical solution, when people turn the handle to open the window sash, the second rotating roller rotates, which drives the first rotating roller to rotate. The rotation of the first rotating roller drives the pressure rod to move along with the rotating rod. The movement of the pressure rod drives the squeezing block to squeeze the sponge to move, thereby squeezing out the water from the sponge, reducing the weight of the sponge, and then causing the first gear and the limiting block to mesh, thus activating the limiting effect on the window sash.
[0022] Preferably, a dustproof net is provided inside the rainwater collection trough.
[0023] By adopting the above technical solution, the dustproof net can reduce the amount of dust falling into the rainwater collection trough, thereby reducing the possibility of the water inlet channel being blocked.
[0024] Preferably, rubber pads are fixedly installed on the four walls of the window frame, and the window sash abuts against the rubber pads.
[0025] By adopting the above technical solution, when the window sash is closed, the rubber pad can reduce the rigid contact between the window sash and the window frame. In addition, the rubber pad can increase the airtightness of the ventilation window and reduce the possibility of moisture entering.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. When people open windows daily, the limiting component can limit the window and fix the position of the window sash, reducing the possibility of the window sash rotating. When the window is open and it rains, rainwater falls into the rain collection channel and drives the closing component to close the window sash, thereby reducing the entry of rainwater and moisture in the air into the room, thus reducing the possibility of indoor bedding and other items becoming damp and improving people's living comfort.
[0028] 2. When the window sash is rotated, the limiting block rotates along with it. At this time, the first gear is fixed, and the limiting block rotates against the second torsion spring. When the limiting block moves away from the first gear, it inserts into the next tooth slot of the first gear under the action of the second torsion spring, until the window sash stops rotating. Then, the limiting block, under the action of the second torsion spring, inserts into the first gear, thus fixing the window sash in place.
[0029] 3. When people turn the handle to open the window sash, the second rotating roller rotates, which drives the first rotating roller to rotate. The rotation of the first rotating roller drives the pressure rod to move along with the rotating rod. The movement of the pressure rod drives the squeezing block to squeeze the sponge, thereby squeezing out the water from the sponge, reducing the weight of the sponge, and then causing the first gear and the limiting block to mesh, thus starting the limiting action on the window sash.

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0038] This application discloses a ventilation wall structure 1, such as... Figure 1 As shown, the ventilation window 2 on the wall 1 includes a window frame 3 and a rotating window sash 4 inside the window frame 3. The window sash 4 is rectangular. The upper and lower inner walls of the window frame 3 are respectively provided with fixing grooves 5 in the vertical direction. Fixing rods 6 are fixedly installed in the fixing grooves 5. The fixing rods 6 are cylindrical, and the two ends of the fixing rods 6 are respectively fixedly welded to the inner walls of the two fixing grooves 5. The window sash 4 rotates on the fixing rods 6. The window sash 4 abuts against the inner wall of the window frame 3. Rubber pads 38 are fixedly adhered to the four walls of the window frame 3. The window sash 4 abuts against the rubber pads 38. When the window sash 4 is closed, the rubber pads 38 can reduce the rigid contact between the window sash 4 and the window frame 3. In addition, the rubber pads 38 can increase the airtightness of the ventilation window 2 and reduce the possibility of water vapor entering. The two ends of the fixing rod 6 are respectively fitted with the first torsion spring 7, which is located in the fixing groove 5. The two torsion arms of the first torsion spring 7 are fixedly welded to the side wall of the window sash 4 and the inner wall of the fixing groove 5. The window sash 4 is provided with a limiting component 8 to limit its own movement.
[0039] like Figure 2As shown, a rainwater collection trough 9 is provided on the upper surface of the window, and the length of the rainwater collection trough 9 is close to the width of the window sash 4, thereby improving the efficiency of rainwater collection. The rainwater collection trough is funnel-shaped, and the inner wall of the lowest end of the rainwater collection trough 9 is connected to a water inlet channel 16. The water inlet channel 16 passes through the inner wall of the top of the storage tank 11 and is connected to the storage tank 11; thus, it can collect the rainwater in the rainwater collection trough. A dustproof net 37 is provided inside the rainwater collection trough 9, which can reduce the amount of dust falling into the rainwater collection trough 9, thereby reducing the possibility of the water inlet channel 16 being blocked. A closing component 10 for closing the window sash 4 is provided inside the rainwater collection trough 9.
[0040] like Figure 1 He Ru Figure 2 As shown, when people open the window daily, the window sash 4 rotates to the fixed rod 6. The limiting component 8 can limit the window sash 4, fix the position of the window sash 4, and reduce the possibility of the window sash 4 rotating. When the window is open, when it rains, rainwater falls into the rain collection trough 9 and enters the storage trough 11 through the water inlet channel 16, thereby driving the closing component 10 to close the window sash 4, thereby reducing the entry of rainwater and moisture in the air into the room, thus reducing the possibility of indoor bedding and other items becoming damp, and improving people's living comfort.
[0041] like Figure 2 and Figure 3 As shown, a placement groove 24 is provided at the end of the window sash 4 away from the fixing rod 6. The placement groove 24 extends horizontally, and a cuboid-shaped insert 25 slides horizontally within the placement groove 24. A second spring 26 is installed within the placement groove 24, and the second spring 26 is horizontally positioned. Both ends of the second spring 26 are fixedly welded to the insert 25 and the inner wall of the placement groove 24, respectively. A bevel 27 is provided at the end of the insert 25 away from the second spring 26. A slot 28 is provided on the window frame 3 for the insert 25 to be inserted into. A drive assembly 29 is provided on the window sash 4 to drive the insert 25 to move. When the window sash 4 is closed, the bevel 27 on the insert 25 abuts against the window frame 3, and the window frame 3 pushes the insert 25 to compress the second spring 26. When the window sash 4 is fully closed, the insert 25 is inserted into the slot 28 under the action of the second spring 26, thereby strengthening the closing of the window sash 4 and reducing the opening of the window sash 4 under the action of external wind.
[0042] like Figure 2 and Figure 3As shown, the drive assembly 29 includes a second gear 30, a rack 31, a handle 32, and a rotating rod 39. The handle 32 rotates on the side wall of the window sash 4. The rotating rod 39 is cylindrical, and its axis is set horizontally. The two ends of the rotating rod 39 rotate on opposite inner walls of the placement groove 24. The handle 32 is fixedly welded to one end of the rotating rod 39. The second gear 30 is fixedly sleeved on the rotating rod 39 and rotates within the placement groove 24. The rack 31 slides within the placement groove 24, and the second gear 30 and rack 31 mesh. One end of the rack 31 is fixedly welded to the insert block 25. When people need to open the window sash 4, they first turn the handle 32. The rotation of the handle 32 drives the rotating rod 39 to rotate, which in turn drives the second gear 30 to rotate. The rotation of the second gear 30 drives the rack 31 to rotate, which in turn drives the insert block 25 away from the slot 28 and compresses the second spring 26. Then, people push the handle 32 to open the window sash 4.
[0043] like Figure 2 and Figure 4 As shown, the limiting component 8 includes a first gear 12 and a limiting block 13. A connecting rod 14 is fixedly welded inside the storage groove 11. The connecting rod 14 is cuboid in shape, and its axis is set vertically. The two ends of the connecting rod 14 are fixedly welded to the opposite inner walls of the storage groove 11. The limiting block 13 is sleeved on and rotates around the connecting rod 14. A second torsion spring 15 is provided at the upper and lower ends of the limiting block 13. The second torsion spring 15 is fixedly sleeved on the side wall of the connecting rod 14, and the two torsion arms of the second torsion spring 15 are fixedly welded to the side wall of the connecting rod 14 and the limiting block 13, respectively.
[0044] like Figure 4 and Figure 5 As shown, the first gear 12 is fitted onto the fixed rod 6 and slides along it. A groove 20 is vertically formed on the side wall of the fixed rod 6. A slider 21, rectangular in shape, is welded to the inner wall of the first gear 12 and slides vertically within the groove 20. A limiting block 13 can be inserted into the tooth groove of the first gear 12. When the window sash 4 is rotated, the limiting block 13 rotates with it. At this time, the limiting block 13 moves to abut against the first gear 12, which remains fixed. Therefore, the limiting block 13 rotates against the second torsion spring 15. When the limiting block 13 moves away from the first gear 12, it inserts into the next tooth groove of the first gear 12 under the action of the second torsion spring 15, until the window sash 4 stops rotating. The limiting block 13 then inserts into the first gear 12 under the action of the second torsion spring 15, thus fixing the window sash 4.
[0045] like Figure 2 and Figure 4As shown, the closing assembly 10 includes a sponge 17, a connecting block 18, and a first spring 19. The connecting block 18 is fixedly sleeved on the fixing rod 6 and is located below the first gear 12. The first spring 19 is arranged vertically, and its two ends are respectively fixedly welded to the upper end face of the connecting block 18 and the lower end face of the first gear 12. The sponge 17 is sleeved and slides on the fixing rod 6, and the water inlet channel 16 abuts against the sponge 17. The sponge 17 is located on the upper end face of the first gear 12. Rainwater in the rain collection trough 9 flows into the storage tank 11 through the water inlet channel 16 and is absorbed by the sponge 17, increasing the weight of the sponge 17. When the sponge 17 absorbs a certain amount of water, it pushes the first gear 12 to move against the first spring 19. When the first gear 12 moves away from the limiting block 13, the limiting of the window sash 4 is released, and the window sash 4 rotates to the closed state under the action of the first torsion spring 7, thereby closing the window sash 4.
[0046] like Figure 2 and Figure 4 As shown, a water outlet channel 22 is provided inside the window sash 4. The water outlet channel 22 is inclined. The top end of the water outlet channel 22 passes through the bottom inner wall of the storage tank 11 and is connected to the storage tank 11. The bottom end of the water outlet channel 22 passes through the lower end face of the window sash 4 and is connected to the outside. A squeezing component 23 that can squeeze the sponge 17 is provided inside the storage tank 11. The extrusion assembly 23 includes an extrusion plate 33, a pressure rod 34, and a rotating rod 35. The extrusion plate 33 is lightweight and cylindrical, with its axis arranged vertically. The extrusion plate 33 is fitted and slidably mounted on the fixed rod 6. The extrusion plate 33 is located above the sponge 17, with its lower end face abutting against the upper end face of the sponge 17. A flow groove 42 is provided on the extrusion plate 33. The water inlet channel 16 at the top of the storage tank 11 is above the flow groove 42. Rainwater flows out from the water inlet channel 16, passes through the flow groove 42, and reaches the sponge 17, where it is absorbed. At the same time, the flow groove 42 increases the range of rotation of the pressure rod 34, improving the water squeezing effect of the sponge 17.
[0047] like Figure 2 and Figure 4As shown, the rotating rod 35 rotates on the inner wall of the storage groove 11, and the pressure rod 34 is fixedly sleeved on the rotating rod 35. The rotating rod 35 is located above the extrusion plate 33 and abuts against the extrusion plate 33. A first rotating roller 40 is fixedly sleeved on the rotating rod 35, and a second rotating roller 41 is fixedly sleeved on the rotating rod 39. The first rotating roller 40 and the second rotating roller 41 are connected by a belt 36. After the rain stops, when people need to open the window sash 4 again, they turn the handle 32 to push the window. The rotation of the handle 32 drives the second rotating roller 41 to rotate, and the rotation of the second rotating roller 41 drives the first rotating roller 40 to rotate. The rotation of the first rotating roller 40 drives the pressure rod 34 to move with the rotating rod 35. The movement of the pressure rod 34 pushes the extrusion block to squeeze the sponge 17, thereby squeezing out the water in the sponge 17. The squeezed water flows out of the window sash 4 through the water outlet channel 22 and reduces the weight of the sponge 17. Under the push of the first spring 19, the sponge 17 causes the position of the limiting block 13 to move upward and mesh with the first gear 12, continuing to activate the limiting function of the window sash 4.
[0048] The implementation principle of this application embodiment is as follows: When people open the window daily, the limiting component 8 can limit the window and fix the position of the window sash 4, reducing the possibility of the window sash 4 rotating; when the window is open and it rains, rainwater falls into the rain collection groove 9 and drives the closing component 10 to close the window sash 4, thereby reducing the entry of rainwater and moisture in the air into the room, thereby reducing the possibility of indoor bedding and other items becoming damp and improving people's living comfort.
[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
