Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sound insulation wooden doors, in particular to a modular sound insulation wooden door. BACKGROUND

[0002] Doors are essential decoration materials for indoor decoration. Common doors include wooden doors, iron doors, or aluminum alloy doors, etc. In today's fast-paced life, most people need a quiet environment to relax after a busy day. Therefore, in indoor decoration, the sound insulation of doors is also an important factor considered by people. Wooden doors have good sound insulation performance, and decorating with wooden doors can also bring a simple and stable style, which is a mainstream choice for indoor decoration.

[0003] Solid wood doors are the best in sound insulation among wooden doors, but they are too heavy to install, and they can easily become skewed due to their weight after long-term use, which can cause the door panel to not fit the door frame. In addition, poor fire resistance is one of the shortcomings of wooden doors.

[0004] In the prior art, a Chinese invention patent with the application number CN201910468577.8 and the name "Wooden door with modularization and good sound insulation effect and using method thereof" proposes a modular wooden door. A cavity structure is provided inside the door panel of the wooden door, and a fire-retardant board and a sound insulation board are provided inside the cavity structure, which reduces the weight of the wooden door while improving the sound insulation and fire resistance of the wooden door. In addition, the patent also provides a ventilation cavity on the door panel of the wooden door, which facilitates the exchange of gas between the inside of the room and the outside of the room. And inside the ventilation cavity, a slope plate one and a slope plate two are rotatably provided, which can control the opening and closing of the ventilation cavity by rotating the slope plate one and the slope plate two, thereby realizing the connection and disconnection of the space inside the wooden door and the space outside the wooden door.

[0005] However, in the above-mentioned invention patent, the opening of the ventilation cavity needs to be manually controlled by rotating the shaft fixedly connected with the slope plate one and the slope plate two through the cross slot. When the room does not need ventilation, the shaft needs to be rotated through the cross slot to close the ventilation cavity to ensure the sound insulation effect of the wooden door. The cross slot is provided on the side edge of the door panel, which is blocked by the door frame when the wooden door is closed, making it inconvenient to adjust the shaft through the cross slot. If a fire occurs at this time, and the ventilation cavity is in an open state, toxic smoke will enter the room through the ventilation cavity, which is not conducive to the survival of people inside the room in the fire.

[0006] Therefore, a modular sound insulation wooden door is proposed. SUMMARY

[0007] The modular soundproof wooden door aims to improve the convenience of the soundproof wooden door while ensuring the soundproofing and ventilation effects of the soundproof wooden door, so as to improve the protection effect of the soundproof wooden door on the room in case of fire.

[0008] To achieve the above object, the present application provides the following technical scheme:

[0009] The modular soundproof wooden door comprises a door plate made of wood material, a soundproof cavity is formed in the side wall of the door plate towards the inside of the door plate, a side plate for closing the soundproof cavity can be detachably installed on the side wall of the door plate, two L-shaped supporting plates are arranged in the soundproof cavity, the L-shaped supporting plates comprise vertical parts and horizontal parts, the two supporting plates are symmetrically fixed and installed on the opposite two sides in the soundproof cavity through the vertical parts, and the horizontal parts of the two supporting plates are oppositely arranged, the soundproof cavity is divided into a soundproof part and a ventilation part by the horizontal parts of the supporting plates, the soundproof part is in communication with the ventilation part, a soundproof plate is arranged in the soundproof part, a fireproof assembly is further arranged in the soundproof part, the bottom of the soundproof plate is placed on the horizontal part of the L-shaped supporting plate to prevent the soundproof plate from falling into the ventilation part, a ventilation hole is further arranged on the door plate, the ventilation hole is aligned with the ventilation part and penetrates through the front and back surfaces of the door plate, a first accommodating groove is formed in the back surface of the door plate, a first sealing plate for closing the ventilation hole is rotatably installed in the first accommodating groove, the rotation shaft position of the first sealing plate is located on the upper side of the first accommodating groove, a torsional spring is arranged at the rotatable installation position of the first sealing plate, the torsional spring is used for keeping the first sealing plate upwardly rotated, and a lock catch is arranged on the back surface of the door plate and used for locking the first sealing plate in the first accommodating groove.

[0010] The soundproof plate is made of polyester fiber soundproof cotton, the soundproof cotton is arranged in the soundproof part, compared with the traditional solid wooden door, the weight of the door plate is reduced, the installation of the door plate is facilitated, and the soundproof effect of the door plate is ensured, the ventilation hole can connect the indoor and outdoor, and the soundproof door has the ventilation effect in the use process. The first sealing plate and the lock catch are arranged on the back surface of the door plate, the user can quickly reach them, the user can conveniently open or close the ventilation hole, and the convenience of the soundproof wooden door in use is improved.

[0011] Preferably, the L-shaped supporting plate is made of memory metal material, and the horizontal part and the vertical part of the supporting plate are integrally bent from the memory metal material. After the supporting plate exceeds the metamorphic temperature, the horizontal part is deformed and becomes vertical with the vertical part. The L-shaped supporting plate made of memory metal can be used to detect the temperature of the environment. When the temperature of the environment is higher than the metamorphic temperature of the supporting plate, the horizontal part of the supporting plate will automatically become vertical. At this time, the sound insulation plate loses the support of the horizontal part of the supporting plate and falls into the ventilation part under the action of gravity, blocks the ventilation hole, prevents the toxic smoke in the fire from passing through the door plate from the ventilation hole, and has the effect of automatic protection in the fire. Automatically prevent people from being harmed by toxic gases after a fire in their sleep. It not only ensures the sound insulation effect, but also saves time for people to escape in a fire.

[0012] The ventilation part is arranged below the sound insulation part with the supporting plate as the boundary. Cold air is located below. When the airflow flows, the cold air flows through the inside of the ventilation cavity. The airflow can cool the supporting plate to a certain extent, avoiding the automatic triggering of the supporting plate due to the hot weather after reaching the metamorphic temperature, and helping to ensure the stability of the supporting plate during use.

[0013] Preferably, the fireproof assembly includes a water bag arranged inside the sound insulation plate. The water bag stores water inside. The sound insulation plate is provided with a puncture hole at the bottom of the water bag. The ventilation part is fixedly installed with a needle. The needle is aligned with the puncture hole. When the sound insulation plate falls into the inside of the ventilation part, the needle is inserted into the inside of the puncture hole and punctures the water bag.

[0014] When the water bag is arranged, its area should cover the area of the sound insulation plate as much as possible. The arrangement of the water bag helps to absorb high-frequency sound waves during sound insulation, further improving the sound insulation effect. When the horizontal part of the supporting plate becomes vertical, the sound insulation plate loses support and falls into the ventilation part. At this time, the needle will insert into the inside of the puncture hole and puncture the water bag. After the water bag is punctured, water flows out of the puncture hole and wets the sound insulation plate. Since the sound insulation plate is made of polyester fiber sound insulation cotton and has a plurality of loose pores inside, the water flowing out of the water bag can spread upward along the sound insulation plate under capillary action and cover more area of the sound insulation plate. The excess water remains at the bottom of the ventilation part to moisten the underside of the door plate, preventing the door plate from being burned through, and helping to delay the fire from passing through the door plate, saving time for people to escape. When the water wets the sound insulation plate, part of the toxic smoke in the fire will be absorbed by the wet sound insulation plate when the toxic smoke enters the ventilation cavity through the communication hole, preventing the toxic smoke from passing through the door plate, helping to isolate the toxic smoke, and the water has a heat absorption effect, helping to prevent the sound insulation plate from being quickly burned through by the flame, further saving time for people to escape in a fire.

[0015] The addition of water bags also increases the weight of the sound insulation panel, effectively adding counterweight to it. This allows the sound insulation panel to quickly fall and block the ventilation holes during a fire, further ensuring the door panel's protection against toxic fumes during a fire.

[0016] Preferably, the ventilated section has a second receiving groove, which is the same size as the first receiving groove. The second receiving groove is located on the side of the ventilated section near the front of the door panel. A second sealing plate, which is the same size as the first sealing plate, is rotatably installed inside the second receiving groove. The pivot of the second sealing plate is located above the second receiving groove, and the pivots of the first and second receiving grooves are at the same horizontal height. The second sealing plate is parallel to the first sealing plate. An avoidance groove is provided on the side of the receiving groove near the first sealing plate. A connecting rod is provided inside the avoidance groove, parallel to the bottom surface of the door panel. The connecting rod is located between the first and second sealing plates. A guide groove is provided on the side of the first sealing plate facing the second sealing plate. A movable block is slidably installed inside the guide groove. One end of the connecting rod is rotatably connected to the movable block.

[0017] To ensure airflow through the vents into the room, the soundproofing panel is not inserted into the vents, resulting in reduced sound insulation at the vent area. However, installing a second sealing plate helps improve sound insulation at the vent area when the vents are closed.

[0018] The second sealing plate is connected to the first sealing plate via a connecting rod. This creates a structure similar to a parallel four-bar linkage, allowing the user to move the second sealing plate synchronously when controlling the first sealing plate. Specifically, when the first sealing plate is housed inside the first receiving groove, the connecting rod moves the second sealing plate synchronously into the second receiving groove, and both the first and second sealing plates effectively seal the vent. When the first sealing plate rotates upwards and leaves the first receiving groove, the second sealing plate also rotates synchronously and leaves the second receiving groove. At this point, the first and second sealing plates no longer block the vent, the vent opens, and gas can enter the room through the vent.

[0019] Furthermore, since the connecting rod is horizontally positioned within the vent, in the event of a fire, if the first and second sealing plates are tilted upwards (i.e., the vent is open), and the temperature inside or outside the room exceeds the abnormal temperature of the support plate, the horizontal portion of the support plate will deform into a vertical position. When the sound insulation panel falls downwards under gravity, it will press down on the connecting rod, thereby pulling the first and second sealing plates downwards simultaneously to reseal the vent. This automatically prevents toxic smoke from entering the room or spreading from inside the room to the outside during a fire. The weight of the sound insulation panel also helps prevent the first and second sealing plates from being blown open by the airflow in the fire.

[0020] The design of the linkage, along with the support plate and sound insulation panel, helps to automatically cut off the connection between the inside and outside of the room in the event of a fire at night when people are asleep and the ventilation holes are open, thus buying people precious escape time.

[0021] Preferably, a first magnet is fixedly installed inside the first receiving groove, and a second magnet is fixedly installed on the first sealing plate. When the first sealing plate is completely housed inside the first receiving groove, the first magnet and the second magnet are aligned, and the magnetic poles of the ends of the first magnet and the second magnet that are close to each other are opposite. A sliding groove is horizontally opened on the side plate. The sliding groove is aligned with the first receiving groove and located on the upper side of the first receiving groove. A locking block is slidably installed inside the sliding groove. The end of the locking block away from the first receiving groove is provided with a hemispherical spherical part, and the spherical part extends out of the end face of the side plate. A return spring is also provided inside the sliding groove. The return spring is used to keep the locking block pushed away from the first receiving groove. A triangular pressing part is provided on the side of the locking block near the first receiving groove. The triangular pressing part is horizontally arranged. A pressing groove is provided on the first sealing plate. When the first sealing plate is housed inside the first receiving groove, the pressing groove is aligned with the sliding groove. A triangular pressing block corresponding to the pressing part is horizontally arranged at the opening of the pressing groove.

[0022] When the door is opened, if the first sealing plate is tilted upwards, when the door is opened to its maximum, the pressure between the first sealing plate and the wall overcomes the torque of the torsion spring, causing the first sealing plate to rotate downwards towards the first receiving groove. When the first magnet and the second magnet approach each other, the first magnet attracts the second magnet and overcomes the torque of the torsion spring. The first sealing plate is then attracted and fixed inside the first receiving groove by the first magnet, and the vent is sealed. This achieves the automatic closing of the vent when the door is opened.

[0023] The spherical part on the locking block remains extended beyond the side plate end face under the push of the return spring, and the extension length is the radius of the spherical part. During door closing, the side plate moves towards the door frame. As the door panel enters the door frame, the spherical part on the locking block is pressed against the door frame. Guided by the arc shape of the spherical part, it is pressed towards the first receiving groove and housed inside the slide groove. The return spring is compressed, ensuring the door panel can smoothly enter the door frame. While the spherical part is housed inside the slide groove, the other end of the locking block extends into the first receiving groove. At this time, when the first sealing plate is housed and fixed inside the first receiving groove by the first magnet, the locking block aligns perfectly with the pressing groove on the first sealing plate when it extends into the first receiving groove, and the locking block extends into the pressing groove. As the locking block extends into the compression groove, the triangular compression part on the locking block compresses the compression block inside the compression groove. Both the compression part and the compression block are isosceles triangles, and their apex angles are horizontally opposite each other. This causes the compression part to push the compression block outward from the first receiving groove when it enters the compression groove. The first sealing plate is also pushed towards the first receiving groove and rotates upward. At this time, the first magnet and the second magnet move away from each other, and the magnetic attraction between them weakens. Under the action of its own elasticity, the torsion spring drives the first sealing plate to rotate upward, opening the vent. Air can then pass through the vent and circulate through the door panel. In this way, the first sealing plate automatically opens and the vent automatically opens when the door is closed, eliminating the need for manual control of the vent opening and improving the convenience and intelligence of the soundproof door during use.

[0024] When the door is opened, the wall presses against the first sealing plate, and with the help of the first and second magnets, the first sealing plate can be automatically stored inside the first receiving slot and the vent is closed, preventing the first sealing plate from being tilted upwards and affecting people's entry and exit.

[0025] Furthermore, if the user needs to disable the automatic vent opening function, when closing the door (i.e., when the spherical part is pressed and retracted into the slide groove), the user can press the first sealing plate by hand, rotate the first sealing plate, and retract it into the first receiving groove. At this time, the first magnet attracts the second magnet, the torsion spring cannot drive the first sealing plate to rotate upward, and the pressing part on the locking block is retracted into the pressing groove and misaligned with the pressing block on the pressing groove. The pressing part will not interfere with the pressing block, nor will it push the first sealing plate outward from the first receiving groove. The first and second sealing plates are closed and retracted into the first and second receiving grooves, and the vent is closed. When the door is opened again, without the obstruction of the door frame, the return spring drives the locking block to return to its original position. The pressing part on the locking block moves horizontally along the slide groove towards the spherical part. During the movement, the pressing part presses the pressing block, pushing the pressing block away from the first receiving groove. The torsion spring, together with the pressing block, overcomes the magnetic force of the first and second magnets, rotating the first sealing plate upward, opening the vent. At this time, the locking block can return to its original position under the action of the return spring, and the spherical part extends out of the side plate end face. When the door is opened to its maximum, the pressure of the wall on the first sealing plate will cause it to retract back into the first receiving slot, thus achieving an automatic closed loop of the function.

[0026] When it is necessary to completely disable the automatic vent opening function, simply press the first sealing plate with your hand while the spherical part is pressed into the receiving groove, rotate the first sealing plate to retract it into the first receiving groove, and then lock the first sealing plate with the latch. The first sealing plate will then be locked inside the first receiving groove. In this way, even if the spherical part is no longer pressed by the door frame, the return spring cannot drive the pressing part on the locking block past the pressing block under the action of the latch, and the spherical part on the locking block will no longer protrude from the side plate end face, so the spherical part will not affect the opening and closing of the door.

[0027] Preferably, the fireproof component further includes two fireproof plates fixedly installed inside the soundproof section. The fireproof plates are respectively fixedly installed on the inner walls of the soundproof section on both sides of the soundproof plate and are parallel to the soundproof plate. The fireproof plates can be made of metal or other fireproof materials, such as rock wool, fireproof polyurethane foam, etc., and then fixedly installed on the inner walls of the soundproof section on both sides of the soundproof plate.

[0028] Fireproof boards further improve the fire resistance of door panels. At the same time, the sound insulation section causes the door panel to be hollow, which reduces the strength of the door panel. Adding fireproof boards helps to increase the solid thickness of the door panel, thereby ensuring the structural strength of the door panel.

[0029] Preferably, both the first sealing plate and the second sealing plate are made of sound-insulating material.

[0030] Both the first and second sealing plates can be made of polyester fiber sound insulation cotton, glass fiber sound insulation cotton, rock wool sound insulation cotton, or other sound insulation materials. Using sound insulation materials for the first and second sealing plates helps to further improve the sound insulation effect of the door panel when the ventilation holes are closed.

[0031] Preferably, a filter screen for blocking dust is fixedly installed on the vent hole, and the filter screen is located on the vent hole port near the front side of the door panel.

[0032] The filter helps to filter the air entering the room through the vent when the vent is open, preventing dust and debris from entering the room. The filter is located at the vent port on the front of the door panel, so it is not obstructed by the first sealing plate, making it convenient for users to replace the filter.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] 1. The modular soundproof wooden door designed in this invention incorporates a ventilation section and a sound insulation section inside the door panel. The sound insulation section contains a sound-insulating board, improving the sound insulation effect of the wooden door. The ventilation section has ventilation holes that allow air to flow into the room even when the door is closed. Furthermore, a first sealing plate is located at the back of the door panel to open or close the ventilation holes, ensuring sound insulation while facilitating easy operation and enhancing the convenience of using the soundproof wooden door.

[0035] 2. The modular soundproof wooden door designed in this invention also features a support plate made of shape memory metal. The support plate holds the soundproof panel, and in the event of a fire, the deformation of the support plate causes the soundproof panel to automatically fall and seal the ventilation holes, preventing toxic fumes from passing through the door panel through the ventilation holes during a fire. This helps to buy people time to escape during a fire. Furthermore, when the soundproof panel falls, the compression rod can simultaneously pull the first sealing plate and the second sealing plate to seal the ventilation holes, further improving the isolation effect against toxic fumes.

[0036] 3. The modular wooden door designed in this invention also incorporates a water bag inside the sound insulation panel. The water stored in the bag absorbs high-frequency sound waves, further improving the sound insulation effect of the wooden door. The water in the bag also provides counterweight to the sound insulation panel, helping it to quickly fall and block the ventilation holes in the event of a fire. Furthermore, a piercing needle is installed inside the ventilation cavity. When the sound insulation panel falls, the needle pierces the water bag, allowing the water in the bag to wet the sound insulation panel, further enhancing the door panel's ability to isolate toxic fumes.

[0046] Please see Figures 1 to 8 This invention provides a modular soundproof wooden door, the technical solution of which is as follows:

[0047] A modular soundproof wooden door, reference Figures 1 to 8The system includes a door panel 1, which is made of wood. A soundproof cavity 2 is formed in the side wall of the door panel 1 facing inwards. A side panel 3 is also provided on the side wall of the door panel 1 to seal the soundproof cavity 2. The side panel 3 is fixedly connected to the side of the door panel 1 by countersunk bolts. Two "L"-shaped support plates 4 are provided inside the soundproof cavity 2. The "L"-shaped support plates 4 include a vertical portion 401 and a horizontal portion 402. The "L"-shaped support plates 4 are made of shape memory metal, and the horizontal portion 402 and the vertical portion 401 of the support plate 4 are integrally bent from shape memory metal. The deformation temperature of the support plate 4 can be set within the range of 50°C to 60°C. After the support plate 4 exceeds the deformation temperature, the horizontal portion 402 deforms and becomes vertical, located on the same plane as the vertical portion 401. An abnormal temperature range of 50°C to 60°C can quickly detect the presence of a fire, improving the response speed of the tray 4. Furthermore, the daily temperature in most areas does not reach above 50°C; therefore, setting an abnormal temperature of 50°C to 60°C can effectively prevent accidental activation of the tray 4 due to excessively high daily temperatures. In this embodiment, the abnormal temperature of the tray 4 is selected as 50°C.

[0048] refer to Figure 3 , Figure 5 , Figure 7 and Figure 8 Two support plates 4 are symmetrically fixed and installed on two opposite sides of the sound insulation cavity 2 through vertical parts 401, and the horizontal parts 402 of the two support plates 4 are arranged opposite each other. The sound insulation cavity 2 is divided into a sound insulation part 201 and a ventilation part 202 by the horizontal part 402 of the support plates 4.

A needle 13 is fixedly installed inside the ventilation section 202, and the needle 13 is aligned with the puncture hole 12. The fireproofing component also includes two fireproof plates 29 fixedly installed inside the soundproofing section 201. The fireproof plates 29 are both aluminum alloy plates with a thickness of 2mm. The fireproof plates 29 are fixedly installed on the inner walls of the soundproofing section 201 on both sides of the soundproofing panel 5 and are parallel to the soundproofing panel 5.

[0052] refer to Figure 4 , Figure 5 and Figure 8 A second receiving groove 14 is provided inside the ventilation section 202. The second receiving groove 14 is located on the side of the ventilation section 202 near the front of the door panel 1.

The movable block 19 helps to prevent the connecting rod 17 from getting stuck.

[0053] To further improve the sealing effect of the first sealing plate 8 and the second sealing plate 15, the interior of the first sealing plate 8 and the second sealing plate 15 can also be configured with a porous structure, so that the sound energy is consumed inside the porous structure after it is transmitted into the first sealing plate 8 and the second sealing plate 15.

[0054] refer to Figure 4 , Figure 5 , Figure 6 as well as Figure 8 A first magnet 20 is fixedly installed inside the first receiving groove 7, and a second magnet 21 is fixedly installed on the first sealing plate 8. When the first sealing plate 8 is completely housed inside the first receiving groove 7, the first magnet 20 and the second magnet 21 are aligned, and the magnetic poles of the ends of the first magnet 20 and the second magnet 21 that are close to each other are opposite. A sliding groove 22 is horizontally opened on the side plate 3. The sliding groove 22 is aligned with the first receiving groove 7 and is located on the upper side of the first receiving groove 7. A locking block 23 is slidably installed inside the sliding groove 22. A hemispherical spherical part 24 is provided at the end of the locking block 23 away from the first receiving groove 7, and the spherical part 24 extends out of the end face of the side plate 3. A return spring 25 is also provided inside the sliding groove 22, which is used to keep the locking block 23 pushed away from the first receiving groove 7. A triangular pressing part 26 is provided on the side of the locking block 23 near the first receiving groove 7, and the triangular pressing part 26 is horizontally arranged. The first sealing plate 8 is provided with an extrusion groove 27. When the first sealing plate 8 is housed inside the first receiving groove 7, the extrusion groove 27 is aligned with the sliding groove 22. A triangular extrusion block 28 corresponding to the extrusion part 26 is horizontally arranged at the opening of the extrusion groove 27.

[0055] During installation, the side of the door panel 1 opposite to the side panel 3 serves as the side where the door panel 1 is hinged to the door frame. The back of the door panel 1 where the first receiving groove 7 is located faces the inside of the room, and when the door is opened, the door panel 1 rotates in the direction of the first receiving groove 7 so that the first sealing plate 8 can be pushed into the first receiving groove 7 using the wall side.

[0056] During use, refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 8Under normal circumstances, the return spring 25 always pushes the ball part 24 out of the end face of the side plate 3. When the door is closed, the door frame squeezes the ball part 24, pushing the ball part 24 and the locking block 23 along the slide groove 22 toward the first receiving groove 7. If the first sealing plate 8 is stored inside the first receiving groove 7 at this time, the second sealing plate 15 is also stored inside the second receiving groove 14 under the action of the connecting rod 17. At this time, after the ball part 24 is squeezed by the door frame, the end of the locking block 23 away from the ball part 24 will extend into the first receiving groove 7. When the locking block 23 extends into the first receiving groove 7, it is aligned with the squeezing groove 27 on the first sealing plate 8. The locking block 23 will extend into the squeezing groove 27. During the process of the card block 23 extending into the compression groove 27, the triangular compression part 26 on the card block 23 will compress the compression block 28 inside the compression groove 27. Both the compression part 26 and the compression block 28 are isosceles triangles, and at this time, the apex angles of the triangles of the compression part 26 and the compression block 28 are opposite each other in the horizontal direction. This causes the compression part 26 to compress the compression block 28 outward from the first receiving groove 7 when it enters the compression groove 27. The first sealing plate 8 is also compressed towards the first receiving groove 7 and rotates upward. At this time, the first magnet 20 and the second magnet 21 move away from each other, and the magnetic attraction between the first magnet 20 and the second magnet 21 weakens. Under the action of its own elasticity, the torsion spring 9 drives the first sealing plate 8 to rotate upward. The second sealing plate 15 also rotates upward with the first sealing plate 8 under the action of the connecting rod 17 and the first sealing plate 8, so that the vent 6 is opened, and air can pass through the vent 6 and the door panel 1 to achieve air circulation.

[0057] refer to Figures 5 to 8 If the user needs to close the vent 6, when the door is closed, i.e., when the spherical part 24 is pressed and retracted into the slide groove 22, the user presses the first sealing plate 8 by hand, rotates the first sealing plate 8 and retracts it into the first receiving groove 7. At this time, the first magnet 20 attracts the second magnet 21, the torsion spring 9 cannot drive the first sealing plate 8 to rotate upward, and at this time the pressing part 26 on the locking block 23 is retracted into the pressing groove 27 and misaligned with the pressing block 28 on the pressing groove 27. The pressing part 26 will not interfere with the pressing block 28, nor will it press the first sealing plate 8 outward into the first receiving groove 7. The first sealing plate 8 and the second sealing plate 15 are closed and retracted into the first receiving groove 7 and the second receiving groove 14, and the vent 6 is closed. At this time, after the first sealing plate 8 and the second sealing plate 15 close the vent 6, they work together with the door panel 1, the sound insulation plate 5, and the water bag 11 to block sound, reduce the sound transmitted from outside the door to the inside, and provide a quiet resting environment for the people in the room.

[0058] The sound insulation panel 5, the first sealing panel 8, and the second sealing panel 15 are all cut from polyurethane sound insulation cotton, which can effectively block the transmission of sound. The water bag 11 inside the sound insulation panel 5 contains water, which has a good blocking effect on high-frequency sound waves and can further block sound from passing through the door panel 1.

[0059] When the door is opened, the obstruction of the door frame is removed, and the return spring 25 drives the locking block 23 to reset. The pressing part 26 on the locking block 23 moves horizontally along the slide groove 22 toward the spherical part 24. During the movement, the pressing part 26 presses the pressing block 28, pressing the pressing block 28 away from the first receiving groove 7. The torsion spring 9, together with the pressing block 28, overcomes the magnetic force of the first magnet 20 and the second magnet 21, and rotates the first sealing plate 8 upward, opening the vent 6. At this time, the locking block 23 can be reset under the action of the return spring 25, and the spherical part 24 extends out of the end face of the side plate 3.

[0060] When the door is fully open, refer to Figure 5 By pressing the first sealing plate 8 against the wall, and with the help of the first magnet 20 and the second magnet 21, the first sealing plate 8 can be automatically stored inside the first receiving groove 7 and the vent 6 can be closed, so as to prevent the first sealing plate 8 from being in an upward tilted state and affecting people's entry and exit.

[0061] When the door is closed, ventilation vent 6 is open, and the person is asleep, refer to... Figure 5 and Figure 8 If a fire occurs outside the room, and the outside temperature continues to rise, when the outside temperature exceeds the abnormal temperature of the support plate 4 (50°C), the horizontal part 402 of the support plate 4 will deform into a vertical state. At this time, under the weight of the sound insulation board 5 and the water bag 11, the sound insulation board 5 falls downward into the ventilation section 202. The piercing needle 13 located in the ventilation section 202 inserts into the piercing hole 12 and punctures the water bag 11. The water inside the water bag 11 flows out and adheres to the sound insulation board 5. Since the sound insulation board 5 is made of polyester fiber sound insulation cotton and has many loose pores inside, the water flowing out of the water bag 11 can spread upward along the sound insulation board 5 under capillary action and cover more of the sound insulation board 5 area. The excess water left at the bottom of the ventilation section 202 moistens the lower side of the door panel 1, preventing the door panel 1 from being burned through, helping to slow the fire from passing through the door panel 1, and buying time for people to escape.

[0062] During the process of the sound insulation panel 5 falling into the ventilation section 202, refer to Figure 5The bottom of the soundproof panel 5 will also press down on the connecting rod 17. After being pressed down by the soundproof panel 5, the connecting rod 17 will pull down the first sealing plate 8 and the second sealing plate 15. The first sealing plate 8 and the second sealing plate 15 will rotate downwards and be stored in the first receiving groove 7 and the second receiving groove 14 respectively. At the same time, the first magnet 20 will attract the second magnet 21 to prevent the torsion spring 9 from driving the first sealing plate 8 to rotate upwards. After the first sealing plate 8 and the second sealing plate 15 are stored in the first receiving groove 7 and the second receiving groove 14 respectively, the vent 6 will be sealed, further preventing toxic fumes from entering the room and buying time for people to escape in the fire.

[0063] At the same time, the impact sound of the soundproof panel 5 falling and hitting the bottom of the ventilation section 202, as well as the collision sound when the first magnet 20 and the second magnet 21 attract each other, can wake people who are asleep and help them escape in a fire.

[0064] During normal use, when it is necessary to completely shut off the function of automatically opening vent 6, refer to... Figure 1 , Figure 2 and Figure 5 When the spherical part 24 is pressed into the groove 22, a person simply presses the first sealing plate 8 by hand, rotates the first sealing plate 8 to house it in the first receiving groove 7, and then rotates the locking rod 1002 to a vertically upward position. The locking rod 1002 then locks the first sealing plate 8 to prevent it from leaving the first receiving groove 7, thus locking the first sealing plate 8 inside the first receiving groove 7. In this way, even if the spherical part 24 is no longer pressed by the door frame, the return spring 25 cannot drive the pressing part 26 on the locking block 23 past the pressing block 28 under the action of the latch 10. The spherical part 24 on the locking block 23 no longer protrudes from the end face of the side plate 3, and the spherical part 24 will not affect the opening and closing of the door. People no longer need to manually close the vent 6 every time, as the vent 6 is set to a normally closed state.

For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
