[0005] An intelligent window control system provided by this application adopts the following technical solution: An intelligent window control system includes a window frame, a window sash, a window opener, and a control component. The window frame has a rotation cavity for the window sash to rotate. The window opener is connected between the window frame and the window sash. The window opener can control the window sash to rotate on the inner wall of the rotation cavity. The window opener is electrically connected to an alarm system. When the alarm system is activated, the window opener is controlled to start, and the window sash rotates away from the rotation cavity and opens the rotation cavity. The control component includes a smoke sensor and a controller. The smoke sensor is connected to the window frame. The smoke sensor and the window opener are electrically connected to the controller. The smoke sensor sends the smoke concentration to the controller. When the controller detects that the smoke concentration exceeds a preset value, the controller controls the window opener to start.

[0006] By adopting the above technical solution, the window frame is embedded in the wall body, the window sash is rotatably connected to the inner wall of the rotating cavity, the window opener is connected between the window frame and the window sash, and the window opener can control the rotation of the window sash on the inner wall of the rotating cavity. When the alarm system is activated, the window opener is powered on and operates. The window opener drives the window sash to rotate away from the window frame on the inner wall of the rotating cavity, and the rotating cavity is opened. The smoke indoors is discharged outdoors through the rotating cavity, realizing the stable discharge of indoor smoke, ensuring that the people indoors are not easily poisoned by inhaling smoke, and thus improving the safety of indoor personnel's escape. At the same time, the controller is electrically connected to the smoke sensor and the controller. The smoke sensor sends the smoke concentration to the controller. When the controller detects that the smoke concentration exceeds the preset value, the controller controls the window opener to be powered on and operate. The window opener controls the window sash to rotate away from the window frame on the inner wall of the rotating cavity, and the rotating cavity is opened. The smoke indoors is discharged outdoors from the rotating cavity, realizing the real-time monitoring of the smoke near the window, further reducing the probability of indoor personnel being poisoned by inhaling smoke, and thus improving the safety of indoor personnel's escape.

[0007] Optionally, a sealing plate is connected to the outer peripheral surface of the window sash, and a sealing cavity for accommodating the sealing plate is provided on the inner wall of the rotating cavity. When the window sash covers the rotating cavity, the sealing plate is embedded in the sealing cavity, and the surface of the sealing plate abuts against the inner wall of the sealing cavity to form a seal.

[0008] By adopting the above technical solution, when the window sash covers the rotating cavity, the sealing plate is embedded in the sealing cavity, and the surface of the sealing plate abuts against the inner wall of the sealing cavity to form a seal, so that external rainwater is not easily infiltrated into the rotating cavity from the abutting part between the surface of the sealing plate and the inner wall of the sealing cavity, thereby improving the sealing performance of the window.

[0009] Optionally, a fastening assembly is connected between the window opener and the window frame. The fastening assembly includes a fastening bolt and a positioning strip. A first threaded hole for the fastening bolt to pass through is provided on the surface of the window opener, and a second threaded hole for the end of the fastening bolt to be tightened is provided on the inner wall of the rotating cavity. The positioning strip is connected to the surface of the window opener, and a positioning cavity for the positioning strip to be embedded is provided on the inner wall of the sealing cavity. When the positioning strip is embedded in the positioning cavity, the first threaded hole corresponds to and communicates with the second threaded hole one by one, and the end of the fastening bolt passes through the first threaded hole and is threadedly tightened and fixed on the inner wall of the second threaded hole to form a fixation.

[0010] By adopting the above technical solution, when the window opener is installed on the window frame, the positioning strip corresponds to and is embedded in the positioning cavity one by one, and the surface of the positioning strip abuts against the inner wall of the positioning cavity to form a positioning, so that the window opener is not easily displaced on the window frame, realizing the preliminary positioning of the window opener on the window frame. At the same time, the first threaded hole corresponds to and communicates with the second threaded hole one by one, and the end of the fastening bolt passes through the first threaded hole and is threadedly tightened and fixed on the inner wall of the second threaded hole to form a fixation, realizing the detachable connection between the window opener and the window frame, and thus facilitating the repair and replacement of the window opener.

[0011] Optionally, the fastening assembly further includes a positioning piston, a first elastic member, and a power piston. A power flow channel for the power piston to slide is provided on the bottom wall of the second threaded hole. The sliding direction of the power piston is parallel to the axis of the second threaded hole. One end of the first elastic member in the direction of its elastic force is connected to the inner wall of the power flow channel, and the other end of the first elastic member in the direction of its elastic force is connected to the surface of the power piston. The first elastic member has an elastic force to drive the power piston to slide towards the second threaded hole, and there is a tendency for the end of the power piston to protrude from the bottom wall of the second threaded hole. A positioning flow channel for the positioning piston to slide is provided on the inner wall of the positioning cavity. The positioning flow channel communicates with the power flow channel. The end face of the positioning piston is flush with the bottom wall of the positioning cavity. A positioning groove for the end of the positioning piston to be embedded is provided on the surface of the positioning strip. When the end face of the fastening bolt abuts against the surface of the power piston and drives the power piston away from the second threaded hole, the positioning piston is pushed towards the positioning groove, and the end of the positioning piston is embedded in the positioning groove, and the surface of the positioning piston is flush with the surface of the positioning strip.

[0012] By adopting the above technical solution, when the positioning strip is embedded in the positioning cavity, the end face of the positioning piston is flush with the bottom wall of the positioning cavity, and the positioning groove communicates with the positioning flow channel. When the end of the fastening bolt passes through the first threaded hole and is threadedly tightened and fixed on the inner wall of the second threaded hole, the end face of the fastening bolt abuts against the end face of the power piston and pushes the power piston to slide along the inner wall of the power flow channel away from the second threaded hole. The end face of the power piston is flush with the bottom wall of the second threaded hole. The power flow channel communicates with the positioning flow channel. The air in the power flow channel impacts the end face of the positioning piston through the positioning flow channel, driving the positioning piston to slide along the inner wall of the positioning flow channel towards the positioning groove. The end face of the positioning piston is flush with the end face of the positioning strip, making it difficult for the positioning strip to shift in the positioning cavity, thereby improving the limit stability of the window opener on the window frame; at the same time, the staff can directly judge the tightening situation of the fastening bolt according to the flush situation between the end face of the positioning piston and the end face of the positioning strip, thereby improving the installation efficiency between the window opener and the window frame.

[0013] Optionally, the fastening assembly further includes a plurality of elastic blocks. The plurality of elastic blocks are connected to the inner wall of the second threaded hole at intervals. The plurality of elastic blocks are spliced to form a circular plate and seal the second threaded hole. When the end of the fastening bolt is embedded in the second threaded hole, the fastening bolt presses the elastic blocks, and the elastic blocks are deformed under pressure. The end face of the fastening bolt and the inner wall of the second threaded hole abut against both sides of the elastic blocks to form a seal.

[0014] By adopting the above technical solution, the plurality of elastic blocks are spliced to form a circular plate and seal the second threaded hole, making it difficult for external impurities to enter the second threaded hole, thereby ensuring the cleanliness of the second threaded hole; when the end of the fastening bolt is embedded in the second threaded hole, the fastening bolt presses the elastic blocks, and the elastic blocks are deformed under pressure. The end face of the fastening bolt and the inner wall of the second threaded hole abut against both sides of the elastic blocks to form a seal, making it difficult for the end of the fastening bolt in the second threaded hole to come into contact with external rainwater and be corroded, thereby further improving the installation firmness of the window opener on the window frame.

[0015] Optionally, a push-pull assembly is connected to the window frame. The push-pull assembly includes a first slider, a second slider, a first connecting rod, and a second connecting rod. A slideway is formed in the inner wall of the window frame. The first slider and the second slider are slidably connected to the inner wall of the slideway at intervals. One end of the first connecting rod is rotatably connected to the end face of the first slider, the other end of the first connecting rod is rotatably connected to the end of the second connecting rod, and the end of the second connecting rod away from the first connecting rod is rotatably connected to the end face of the second slider. When the first connecting rod and the second connecting rod rotate in a direction away from each other, the end faces of the first connecting rod and the second connecting rod are flush and abut against the end face of the window sash facing the rotating cavity. When the first connecting rod and the second connecting rod rotate in a direction close to each other, the end of the first connecting rod and the second connecting rod that are rotatably connected abuts against the surface of the window sash and drives the window sash to rotate away from the window frame.

[0016] By adopting the above technical solution, when the window sash covers the rotating cavity, the first connecting rod and the second connecting rod rotate in a direction away from each other, driving the first slider and the second slider to slide along the inner wall of the slideway in a direction away from each other. The end faces of the first connecting rod and the second connecting rod are flush and abut against the end face of the window sash facing the rotating cavity. When the first connecting rod and the second connecting rod rotate in a direction close to each other, it drives the first slider and the second slider to slide along the inner wall of the slideway in a direction close to each other. The end of the first connecting rod and the second connecting rod that are rotatably connected abuts against the surface of the window sash and drives the window sash to rotate away from the window frame, making it difficult for the window sash to deflect in the rotating cavity, thereby improving the limit stability of the window sash in the rotating cavity.

[0017] Optionally, the push-pull assembly further includes a guide rod. A guide channel for the guide rod to slide is formed in the inner wall of the window frame. The guide channel communicates with the slideway. The end of the guide rod protruding from the inner wall of the window frame is coaxially connected to the rotating shaft of the second connecting rod.

[0018] By adopting the above technical solution, when the first slider and the second slider slide on the inner wall of the slideway, they push the first connecting rod and the second connecting rod to rotate, driving the guide rod to slide on the inner wall of the guide channel, realizing the directional control of the rotation range of the first connecting rod and the second connecting rod, thereby improving the stability of the end of the first connecting rod and the second connecting rod that are rotatably connected and abutting against the surface of the window sash.

[0019] Optionally, the push-pull assembly includes a push-pull rod. The guide channel penetrates the rotating cavity and communicates with the sealing cavity. One end of the push-pull rod is connected to the rod surface of the guide rod, the other end of the push-pull rod faces the sealing plate, and the rod surface of the push-pull rod is flush with the inner wall of the rotating cavity. When the first connecting rod and the second connecting rod rotate in a direction close to each other, the rod surface of the push-pull rod abuts against the plate surface of the sealing plate and drives the sealing plate away from the sealing cavity.

[0020] By adopting the above technical solution, the push-pull rod surface is flush with the inner wall of the rotating cavity, so that the wear between the push-pull rod and the window sash is reduced when the window sash is embedded in the rotating cavity; when the connecting rod 1 and the connecting rod 2 rotate in the direction of approaching each other, the end of the connecting rod 1 and the connecting rod 2 that are rotatably connected abuts the surface of the window sash and drives the window sash to rotate in the direction away from the rotating cavity, and at the same time, the push-pull rod slides along the inner wall of the guide flow channel in the direction close to the sealing cavity, and the push-pull rod surface abuts the sealing plate surface and drives the sealing plate away from the sealing cavity, thereby increasing the force application points on the window sash and achieving uniform force on the window sash, thereby improving the stability of the window sash in the rotating cavity.

[0021] Optionally, the push-pull assembly also includes a limit block, which is rotatably connected to the end face of the push-pull rod away from the sealing plate, the rotation axis of the limit block and the rotation axis of the connecting rod are perpendicular to each other, and the inner wall of the guide channel is provided with a plurality of limit grooves for the end of the limit block to be embedded in. When the limit block is embedded in one of the limit grooves, the outer wall of the limit block abuts against the inner wall of the limit groove to form a limit, and limits the push-pull rod in the guide channel.

[0022] By adopting the above-mentioned technical scheme, when the end of the connecting rod one and the connecting rod two that are rotatably connected abuts against the surface of the window sash and drives the window sash to rotate to a preset angle, the limit block corresponds one-to-one with one of the limit grooves, and the end of the limit block rotates and embeds in the direction close to the limit groove. The outer wall of the limit block abuts against the inner wall of the limit groove and limits the push-pull rod in the guide channel, thereby realizing the limiting of the guide rod in the guide channel, thereby increasing the clamping force between the end of the connecting rod one and the connecting rod two that are rotatably connected and the surface of the window sash.

[0023] Optionally, the push-pull assembly also includes an elastic member 2, one end of the elastic member 2 in the elastic force direction is connected to the rotating shaft of the push-pull rod, and the other end of the elastic member 2 in the elastic force direction is connected to the inner wall of the limit block. The elastic member 2 has an elastic force that drives the limit block to rotate toward the direction close to the limit groove, and the end of the limit block tends to be embedded in the limit groove.

[0024] By adopting the above technical solution, when it is necessary to drive connecting rod one and connecting rod two to rotate, the limit block is driven to overcome the elastic force of elastic member two and rotate in the direction away from the limit groove, and the end of the limit block protrudes out of the inner wall of the window frame, pushing the guide rod to slide on the inner wall of the guide channel. When the end of connecting rod one and connecting rod two that are rotatably connected abuts the surface of the window sash, the limit block faces one of the limit grooves, releases the limit block, and the elastic force of elastic member two drives the limit block to rotate in the direction close to the limit groove, and the end of the limit block is embedded in the limit groove, and the outer wall of the limit block abuts against the inner wall of the limit groove to form a limit, so that the limit block is not easy to separate from the limit groove, thereby improving the limiting stability of the guide rod in the guide channel.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The settings of the smoke sensor and the controller enable the smoke indoors to be discharged outdoors from the rotating cavity, achieving real-time monitoring of the smoke near the window, further reducing the probability of indoor personnel inhaling poisonous smoke, and thus enhancing the safety of indoor personnel's escape. 2. The setting of the sealing plate prevents external rainwater from seeping into the rotating cavity easily from the contact area between the sealing plate surface and the inner wall of the sealing cavity, thereby improving the sealing performance of the window. 3. The settings of the fastening bolt and the positioning strip enable the end of the fastening bolt to pass through the threaded hole and be screwed tightly and fixed on the inner wall of the second threaded hole to form a fixation, realizing the detachable connection between the window opener and the window frame, and thus facilitating the maintenance and replacement of the window opener.

The push-pull rod 76 is embedded in the guide channel 19, and the rod surface of the push-pull rod 76 is flush with the inner wall of the rotation cavity 11, reducing the wear between the push-pull rod 76 and the window sash 2, thereby improving the sealing stability between the window sash 2 and the inner wall of the rotation cavity 11.

[0043] Referring to Figure 2 and Figure 5 , the limit block 77 is rotatably connected to the end of the push-pull rod 76 away from the sealing plate 5. The rotation axis of the limit block 77 is parallel to the width direction of the window frame 1. A plurality of limit grooves 110 for the end of the limit block 77 to be embedded are spaced apart on the inner wall of the guide channel 19. The end of the limit block 77 away from the push-pull rod 76 is provided with a guide surface, and the guide surface is in a circular arc convex shape. The guide surface guides the limit block 77 to be embedded in the limit groove 110, reducing the wear between the limit block 77 and the inner wall of the limit groove 110, thereby improving the pressing force between the surface of the limit block 77 and the inner wall of the limit groove 110.

[0044] Referring to Figure 2 and Figure 5 , the second elastic member 78 can be a compression spring or a torsion spring. In the embodiment of the present application, the second elastic member 78 is a torsion spring and has a certain deformation ability. One end of the second elastic member 78 in the direction of the elastic force is connected to the rotating shaft of the push-pull rod 76, and the other end of the second elastic member 78 in the direction of the elastic force is connected to the inner wall of the limit block 77. The second elastic member 78 has an elastic force to drive the limit block 77 to rotate towards the direction close to the limit groove 110, and there is a tendency for the end of the limit block 77 to be embedded in the limit groove 110.

[0045] Refer to Figure 2 and Figure 5 When the window sash 2 closes the rotating cavity 11, it drives the push-pull rod 76 to slide along the inner wall of the guiding flow channel 19 in a direction away from the sealing cavity 13. The rod surface of the push-pull rod 76 is flush with the bottom wall of the sealing cavity 13, so that the supporting effect of the push-pull rod 76 on the plate surface of the sealing plate 5 disappears. At the same time, the guiding rod 75 slides along the inner wall of the guiding flow channel 19 in a direction away from the rotating cavity 11, driving the first connecting rod 73 and the second connecting rod 74 to rotate in a direction away from each other. The first slider 71 and the second slider 72 slide along the inner wall of the slideway 18 in a direction away from each other. The end surfaces of the first connecting rod 73 and the second connecting rod 74 are flush and abut against the surface of the window sash 2 to achieve storage. The limiting block 77 faces one of the limiting grooves 110 away from the rotating cavity 11. The limiting block 77 is released, and the elastic force of the second elastic member 78 drives the limiting block 77 to rotate in a direction close to the limiting groove 110. The end of the limiting block 77 is embedded in the limiting groove 110, and the outer part of the limiting block 77 abuts against the inner wall of the limiting groove 110 to form a limit, so that the push-pull rod 76 is not easy to move in the guiding flow channel 19, realizing the limiting stability of the push-pull rod 76 in the guiding flow channel 19.

[0046] Refer to Figure 2 and Figure 5 When the window sash 2 rotates along the inner wall of the rotating cavity 11 in a direction away from the window frame 1 and opens the rotating cavity 11, it drives the limiting block 77 to rotate in a direction away from the limiting groove 110 against the elastic force of the second elastic member 78. The end of the limiting block 77 disengages from the limiting groove 110, and the limiting effect of the push-pull rod 76 in the guiding flow channel 19 disappears. It drives the push-pull rod 76 to slide along the inner wall of the guiding flow channel 19 in a direction close to the sealing cavity 13. The rod surface of the push-pull rod 76 abuts against the plate surface of the sealing plate 5 and guides the sealing plate 5 to disengage from the sealing cavity 13. At the same time, the guiding rod 75 slides along the inner wall of the guiding flow channel 19 in a direction close to the rotating cavity 11, driving the first connecting rod 73 and the second connecting rod 74 to rotate in a direction close to each other. The first slider 71 and the second slider 72 slide along the inner wall of the slideway 18 in a direction close to each other. The end of the first connecting rod 73 rotatably connected to the second connecting rod 74 abuts against the surface of the window sash 2 and guides the window sash 2 to rotate in a direction away from the window frame 1, realizing multiple force application points on the surface of the window sash 2, thereby improving the stability of the window sash 2 rotating along the inner wall of the rotating cavity 11. At the same time, the limiting block 77 faces one of the limiting grooves 110. The limiting block 77 is released, and the elastic force of the second elastic member 78 drives the limiting block 77 to rotate in a direction close to the limiting groove 110. The end of the limiting block 77 is embedded in the limiting groove 110, and the outer wall of the limiting block 77 abuts against the inner wall of the limiting groove 110 to form a limit, realizing the stable support for the surface of the window sash 2.

[0047] The implementation principle of an intelligent window control system in an embodiment of this application is as follows: When the alarm system is activated, the control body 31 is powered on and starts. The body 31 drives the chain 32 to extend, pushing the window sash 2 to rotate away from the window frame 1 along the inner wall of the rotation cavity 11, and the rotation cavity 11 is opened. The smoke indoors is discharged outdoors through the rotation cavity 11, eliminating the need for staff to manually control the window opener 3 to start, ensuring that indoor personnel are not easily poisoned by inhaling smoke, and thus improving the safety of indoor personnel's escape. At the same time, the smoke sensor 41 continuously detects the indoor smoke concentration and sends it to the controller. The controller compares the measured value with the preset value. When the controller detects that the measured value exceeds the preset value, the controller controls the body 31 to be powered on. The body 31 drives the chain 32 to extend, driving the window sash 2 to rotate away from the window frame 1 along the inner wall of the rotation cavity 11, and the rotation cavity 11 is opened, realizing real-time monitoring of the smoke near the window, further reducing the probability of indoor personnel being poisoned by inhaling smoke, and thus improving the safety of indoor personnel's escape.

[0048] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
