[0044] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0045] like Figure 1 and Figure 2 , Figure 3 As shown, a sliding and casement multifunctional door and window in one embodiment of the present invention includes a window frame 1, and a window body 2 set on the window frame 1 through a sliding structure 81; the window body 2 includes a sash frame 21, a sash body 23 connected to the sash frame 21 through a casement structure 82, and a safety rupture structure 3; the sash frame 21 includes a frame body 24, and the safety rupture structure 3 includes a folding bag 31 set in the frame body 24, a fragile unit 32 set on the outside of the frame body 24, a filling unit 33 connected to the inside of the folding bag 31, and a safety switch 34 for connecting the inside of the folding bag 31 and the filling unit 33, and the safety switch switches the opening state or the closing state of the filling unit by detecting the indoor temperature.

[0046] Specifically, since the opening direction of the fan body 23 on the fan frame 21 is set according to actual needs, that is, the fan body 23 can be opened to the inside of the house or to the outside of the house on the fan frame 21. In this way, the safety switch 34 is used to control the filling unit 33 to fill the folding bag 31. When an accident occurs, the safety switch 34 is turned on, and the filling unit 33 fills the folding bag 31. The folding bag 31 expands due to the filling, causing the fragile unit 32 to rupture, thereby forming an escape window, which is convenient for people in the house to escape from the escape window or get rescued.

[0047] In one embodiment, the filling unit 33 and the safety switch 34 (attached Figure 1 The safety switch 34 is a temperature sensor and a switch valve electrically connected to the temperature sensor. Specifically, the safety switch 34 also includes a switch power supply for providing power to the temperature sensor and the switch valve. In this way, when the temperature sensor senses a temperature reaching a preset value, the switch valve opens the connecting pipe, and the filling unit 33 fills the folding bag 31.

[0048] In one embodiment, the filling unit 33 includes a compression bottle arranged in the room through a connecting pipe, and a filling material arranged in the compression bottle, and the filling material is compressed dry powder or compressed gas. In this way, when the safety switch 34 is turned on, the filling material in the compression bottle is quickly transferred from the compression bottle to the folding bag 31 due to the change in air pressure, and the filling work is completed.

[0049] like Figure 4As shown, in one embodiment, the safety switch 34 includes a cylinder 341 with a cavity inside, and a thermal-sensitive cylinder core 342, a discharge cylinder 343, a conical cylinder core 344 and a spring 345 which are sequentially arranged in the cavity of the cylinder 341; the discharge cylinder 343 and the conical cylinder core 344 respectively form a sliding seal with the inner cavity of the cylinder 341, the discharge cylinder 343 is provided with a first through hole, and the middle of the conical cylinder core 344 is provided with a flow channel; the inner wall of the cylinder 341 is provided with an abutting portion abutting against the conical cylinder core 344, the cylinder 341 is provided with an injection hole penetrating through the cylinder wall, and the valve end of the cylinder 341 near the spring 345 is provided with a connecting hole connected to the compression bottle; when the thermal-sensitive cylinder core 342 expands due to heat, the spring 345 is squeezed by force, and the filling material passes through the connecting hole, the flow channel, and the first through hole in sequence and is ejected from the injection hole. Specifically, the safety switch 34 is set at the door or wall near the soundproof house using a pipeline according to actual conditions. In this way, since the soundproof material usually has a certain heat preservation ability, by placing the safety switch 34 at the door or wall of the soundproof house, the safety switch 34 can sense the temperature rise earlier than the soundproof house; at the same time, when the thermosensitive cylinder core 342 expands due to heat, the spring 345 is squeezed by force, and the filling material passes through the connecting hole, the flow channel, and the first through hole in sequence and is ejected from the injection hole, so that the filling material in the compressed bottle is quickly transferred from the compressed bottle to the folded bag 31 due to the change in air pressure.

[0050] In one embodiment, the fan body 23 is connected to the fan frame 21 through a flat opening structure 82; the flat opening structure 82 includes a hinge unit 821 connecting the bottom of the fan body 23 and the fan frame 21, and a hinge unit 822 connecting the two sides of the fan body 23 and the fan frame 21; the folding bag 31 is arranged in the fan frame 21 in an inverted U shape; after the folding bag 31 is filled, the fragile unit 32 breaks, the hinge unit 822 is disconnected from the frame body 24, and the fan body 23 rotates downward with the hinge unit 821 as the rotation center, and the fan frame 21 forms an escape window. Specifically, since the opening direction of the fan body 23 on the fan frame 21 is set according to actual needs, that is, the fan body 23 can be opened to the inside of the house or to the outside of the house in the fan frame 21. In this way, after the foldable bag 31 is filled, the fragile unit 32 breaks and makes a sound; when the fan body 23 rotates downward with the hinge unit 821 as the rotation center, a loud noise will be made, thereby alerting people in the house to pay attention and wait / get rescue at the escape window or escape from the soundproof house from the escape window.

[0051] Specifically, the escape method can be to wait for firefighters to use a ladder to descend to the ground.

[0052] like Figure 3As shown, in one embodiment, the fan body 23 and the fan frame 21 achieve a sound insulation effect through a sound insulation structure 6; the sound insulation structure 6 includes a first sound insulation unit 61, a second sound insulation unit 62 and a third sound insulation unit 63 arranged in sequence from inside to outside the house; the first sound insulation unit 61 includes a first sound insulation groove 611 arranged on the inner side of the fan frame 21, and a first sound insulation strip 612 arranged on the fan body 23; the second sound insulation unit 62 includes a second sound insulation strip 621 arranged in the middle of the fan frame 21, and a second connecting strip 622 arranged on the fan body 23; the third sound insulation unit 63 includes a third sound insulation strip 631 arranged on the outer side of the fan frame 21, and a third sound insulation groove 632 arranged on the fan body 23. In this way, the first sound insulation unit 61, the second sound insulation unit 62 and the third sound insulation unit 63 between the fan body 23 and the fan frame 21 form a sound insulation structure 6, and the sound is prevented from being propagated from the gap between the fan body 23 and the fan frame 21 through triple sound insulation.

[0053] In one embodiment, the window frame 1 includes an upper frame 11 and a lower frame 12; the sliding structure 81 includes a first guide rail 101 and a second guide rail 102 arranged on the lower frame 12; the window body 2 includes a first movable fan 201 and a second movable fan 202; the bottom of the first movable fan 201 is provided with a first pulley 203 adapted to the first guide rail 101, and the bottom of the second movable fan 202 is provided with a second pulley 204 adapted to the second guide rail 102.

[0054] like Figure 2 and Figure 5As shown, in one embodiment, the bottom of the first movable fan 201 is sealed and connected to the lower frame 12 through a lower sealing structure 4; the lower sealing structure 4 includes a first flange 41, a second flange 42, a third flange 43, a fourth flange 44, a fifth flange 45, a sixth flange 46, a second sealing strip 421, a third sealing strip 431, a fourth sealing strip 441, a fifth sealing strip 451, and a sixth sealing strip 461 arranged on the sixth flange 46, arranged at the bottom of the first movable fan 201; both sides of the first flange 41 are respectively in contact with the fourth sealing strip 441 and the fifth sealing strip 451, the second sealing strip 421 and the third sealing strip 431 are in contact with the lower frame 12, and the sixth sealing strip 461 is in contact with the outer side of the lower frame 12. In this way, the two sides of the first flange 41 are respectively in contact with the fourth sealing strip 441 and the fifth sealing strip 451, the second sealing strip 421 and the third sealing strip 431 are in contact with the lower frame 12, and the sixth sealing strip 461 is in contact with the outer side of the lower frame 12; the multi-channel sealing design ensures the air tightness and water tightness of the window in the closed state through layer by layer. This design can effectively prevent the cold air outside from entering the house, and prevent the warm air inside from flowing out, so as to keep the temperature inside the house stable and comfortable.

[0055] like Figure 2 and Figure 6 As shown, in one embodiment, the bottom of the first movable fan 201 is sealed and connected to the upper frame 11 through an upper sealing structure 5; the upper sealing structure 5 includes, from the inside to the outside, an upper contact flange 51 arranged on the upper frame 11, a first sealing unit 52 arranged on the top of the first movable fan 201, and a second sealing unit 53 arranged on the upper frame 11.

[0056] In one embodiment, it also includes an overhead component 7, which includes an overhead wheel unit 71 arranged on the top of the first movable sash 201; the upper frame 11 is provided with a limit track 103 adapted to the overhead wheel unit 71. The abnormal noise generated by the sliding window during the opening or closing process is often caused by the friction and collision between the movable window sash and the window frame 1, and the aging and loosening of the sealing strip. Especially in windy weather, the shaking of the window sash will aggravate the generation of these abnormal noises. In this way, the overhead wheel unit 71 is placed on the limit track 103, and the friction and collision sound are reduced by reducing the shaking of the movable window sash; at the same time, the overhead wheel unit 71 can ensure that the movable window sash slides smoothly on the limit track 103, preventing abnormal noise caused by slipping or misoperation. In addition, the multi-channel sealing design also reduces the noise generated by air flow, providing users with a quieter and more comfortable living environment.

[0057] like Figure 2 and Figure 7 As shown, in one embodiment, the top wheel unit 71 includes a mounting seat 72, a top rod 73 rotatably connected to the mounting seat 72, a top wheel body 74 arranged at the end of the top rod 73, and a compression spring 75 for pressing the top rod 73 to generate a tendency to move in the vertical direction. In this way, the compression spring 75 is used to press the top rod 73 to generate a tendency to move in the vertical direction, so that the top wheel body 74 at the end of the top rod 73 is pressed against the upper top wall of the limit track 103, and the position of the window 2 in the window frame 1 is limited by cooperating with the pulley on the lower frame 12 to avoid the occurrence of shaking.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
