Description

Technical Field

[0001] This application relates to the field of ceiling technology, and more specifically, to decorative ceilings with fire extinguishing functions and their usage methods. Background Technology

[0002] Suspended ceilings serve multiple functions, including heat insulation, sound insulation, and sound absorption. They also act as a concealed layer for electrical, ventilation, air conditioning, communication, fire protection, and alarm wiring and equipment. Suspended ceilings are a common element in home decoration. Ceilings are classified differently depending on the material of the decorative panels. The main basis for distinguishing ceiling types is the ceiling material itself, which includes: light steel keel gypsum board ceilings, gypsum board ceilings, mineral wool board ceilings, plywood ceilings, irregularly shaped long strip aluminum composite panel ceilings, square painted aluminum composite panel ceilings, stained glass ceilings, aluminum honeycomb perforated sound-absorbing panel ceilings, and full-room duplex ceilings, etc.

[0003] In existing suspended ceilings, holes are usually made, and fire sprinklers are then installed and connected to water pipes on the ceiling through the holes. However, since the fire sprinklers are installed and exposed outside the suspended ceiling, it is not convenient to retract them into the suspended ceiling when not in use. When moving objects indoors, the fire sprinklers may be bumped and damaged, which also affects the aesthetics of the suspended ceiling.

[0004] In view of this, we propose a decorative ceiling with fire extinguishing function. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] The purpose of this application is to provide a decorative ceiling with fire extinguishing function, which solves the technical problems mentioned in the background art and achieves the technical effect of storing the fire sprinkler head when it is not in use.

[0007] 2. Technical Solution

[0008] This application provides a decorative ceiling with fire extinguishing function, including: a ceiling panel, a connecting mechanism, a storage base, a retractable mechanism, a fire sprinkler head, and a water inlet mechanism. The ceiling panel is movably connected to the upper perimeter of all four sides via the connecting mechanism. The storage base is fixedly connected to the center of the ceiling panel. The retractable mechanism is fixedly connected to the inside of one side of the storage base, and a fire sprinkler head is mounted on the retractable mechanism. The retractable mechanism can retract the fire sprinkler head into the storage base when not in use. The water inlet mechanism is fixedly connected to the storage base and is connected to the fire sprinkler head via a pipe, enabling communication between the fire sprinkler head and an external water source.

[0009] As an optional solution to the technical solution in this application, the ceiling panel has a water guiding cavity inside, and water pipes are connected to both sides of the ceiling panel.

[0010] By adopting the above technical solution, the ceiling panel also has fireproof function.

[0011] As an optional embodiment of the technical solution in this application, the connecting mechanism includes a screw and a plug, with the plug fixedly connected to the bottom of the screw; multiple snap-fit ​​seats are fixedly connected through the ceiling panel near the screw, and the inner wall of each snap-fit ​​seat is movably inserted into the outer wall of the plug. Each snap-fit ​​seat has a slot on its inner wall.

[0012] As an optional solution to the technical solution of this application, the lower inner wall of the insert block is rotatably connected with two locking strips, which are fixedly connected by a spring. The ends of the locking strips are movably engaged with the inner wall of the locking seat. The lower end of the locking seat is slidably fitted with a U-shaped block, and the two ends of the U-shaped block are respectively in movable contact with the outer walls of the two locking strips.

[0013] By adopting the above technical solution, the snap-fit ​​seat on the ceiling panel is aligned and inserted with the plug at the bottom of the screw. Then, the snap-fit ​​strip inside the plug will be locked into the inner wall of the plug under the action of the spring, thereby fixing the ceiling panel.

[0014] As an optional solution to the technical solution of this application, a sealing plate is rotatably connected to the bottom of the storage base, and a connecting rod is rotatably hinged to one side of the sealing plate.

[0015] As an optional solution to the technical solution of this application, the retracting mechanism includes an electric push rod, which is fixedly connected to the inner wall of one side of the storage base, and the end of the electric push rod is hinged to the connecting rod.

[0016] By adopting the above technical solution, the electric actuator is activated, which drives the connected link to move, thereby opening the sealing plate.

[0017] As an optional solution to the technical solution of this application, the retracting mechanism further includes a gear A and a rack A. The gear A is rotatably connected to the inner wall of the storage seat, and the rack A is fixedly connected to one end of the electric push rod. The rack A and the gear A are meshed and driven together.

[0018] As an optional solution to the technical solution of this application, a gear B is coaxially and fixedly connected to the other side of the gear A; a rack B is fixedly connected to one end of the fire sprinkler head, and the rack B is meshed with the gear B for transmission.

[0019] By adopting the above technical solution, when the electric actuator extends, it will drive the connected rack A to move, thereby driving the meshing gear A to rotate. Then, gear A will drive the connected gear B to rotate, which will then drive the meshing rack B to move, thereby driving the connected fire sprinkler head to move out of the storage base.

[0020] As an optional solution to the technical solution of this application, the water inlet mechanism includes a water inlet pipe, a valve plate, and an opening and closing wheel. One end of the water inlet pipe is bifurcated, and one bifurcated end is connected to the fire sprinkler head via a flexible hose. The other bifurcated end of the water inlet pipe extends through the inner wall of the receiving base to the outside and is fixedly connected to one of the water inlet pipes. A valve plate is rotatably connected to the inner wall of one end of the water inlet pipe, and one end of the valve plate extends through the inner wall of the water inlet pipe to the outside and is fixedly connected to the opening and closing wheel. An opening and closing rack is fixedly connected to the fire sprinkler head, and the opening and closing rack is meshed with the opening and closing wheel for transmission.

[0021] By adopting the above technical solution, when the fire sprinkler head moves, the connected opening and closing rack will drive the meshing opening and closing wheel to rotate, thereby driving the connected valve plate to open, allowing external water to enter the fire sprinkler head for fire extinguishing.

[0022] The method for using decorative ceilings with fire extinguishing functions includes the following steps:

[0023] S1. When it is necessary to install a decorative ceiling, first adjust the height of multiple screws and connect them to the ceiling. Then, align the clips on the ceiling panel with the inserts at the bottom of the screws and insert them. The clips inside the inserts will be locked into the inner wall of the clips by the spring, thereby fixing the ceiling panel.

[0024] S2. Then connect one end of the water inlet pipe to the external water pipe, and at the same time connect one of the water inlets on the ceiling panel to the drainage pipe.

[0025] S3. When a fire occurs, the smoke sensor will detect smoke and activate the electric actuator via an electrical signal. The movable rod of the electric actuator moves downward, which will drive the connecting rod to move, thereby opening the sealing plate. At the same time, when the movable rod of the electric actuator extends, it will drive the connected rack A to move, which will drive the meshing gear A to rotate. Then gear A will drive the connected gear B to rotate, which will drive the meshing rack B to move, thereby moving the connected fire sprinkler head out of the storage base.

[0026] S4. At the same time, when the fire sprinkler head moves, the connected opening and closing rack will drive the meshing opening and closing wheel to rotate, which will drive the connected valve plate to open, allowing external water to enter the fire sprinkler head for fire extinguishing.

[0030] 2. By setting a connecting rod, this application can open and close the sealing plate while retracting the fire sprinkler head, realizing the automation of the device. At the same time, the fire sprinkler head can be retracted into the storage base and the sealing plate can be closed, so that the ceiling panel can form a whole plane, thereby making the ceiling panel more aesthetically pleasing and achieving a better decorative effect.

[0031] 3. This application enables the flow of water into the inlet pipe by connecting an opening and closing rack to the fire sprinkler head, allowing external water to enter and achieve the function of fire extinguishing. At the same time, the connection mechanism facilitates the installation and disassembly of the ceiling panel.

[0032] 4. By setting a water channel cavity inside the ceiling panel, cold water can play a role in heat insulation and cooling of the ceiling panel, preventing the ceiling panel from being heated and burning, and protecting the ceiling. Attached Figure Description

[0055] Reference Figures 1-6A method for using a decorative ceiling with fire extinguishing function includes the following steps:

[0056] S1. When it is necessary to install a decorative ceiling, first adjust the height of multiple screws 201 and connect them to the ceiling of the house. Then, align the snap-fit ​​seat 103 on the ceiling panel 1 with the insert block 202 at the bottom of the screw 201 and insert it. Then, the snap-fit ​​strip 203 in the insert block 202 will be snapped into the inner wall of the snap-fit ​​seat 103 under the action of the spring 204, thereby fixing the ceiling panel 1.

[0057] S2. Then connect one end of the water inlet pipe 601 to the external water pipe, and at the same time connect one of the water inlet pipes 102 on the ceiling panel 1 to the drainage pipe.

[0058] S3. When a fire occurs, the smoke sensor detects smoke and activates the electric actuator 401 via an electrical signal. The movable rod of the electric actuator 401 moves downward, causing the connected connecting rod 302 to move, thereby opening the sealing plate 301. At the same time, when the movable rod of the electric actuator 401 extends, it will drive the connected rack A403 to move, thereby driving the meshing gear A402 to rotate. Then, gear A402 will drive the connected gear B404 to rotate, which will then drive the meshing rack B501 to move, thereby causing the connected fire sprinkler head 5 to move out of the storage base 3.

[0059] S4. At the same time, when the fire sprinkler head 5 moves, the connected opening and closing rack 502 will drive the meshing opening and closing wheel 603 to rotate, which will drive the connected valve plate 602 to open, so that external water source can enter the fire sprinkler head 5 for water spraying and fire extinguishing.

[0060] The implementation principle of a decorative ceiling with fire extinguishing function of the present invention is as follows: When it is necessary to install the decorative ceiling, firstly, adjust the height of multiple screws 201 and connect and fix them to the ceiling of the house. Then, align the snap-fit ​​seat 103 on the ceiling panel 1 with the insert block 202 at the bottom of the screw 201 and insert it. Then, the snap-fit ​​strip 203 in the insert block 202 will be snapped into the inner wall of the snap-fit ​​seat 103 under the action of the spring 204, thereby fixing the ceiling panel 1.

[0061] Then, one end of the inlet pipe 601 is connected to the external water pipe, and one of the water inlets 102 on the ceiling plate 1 is connected to the drainage pipe. When a fire occurs, the smoke sensor will detect the smoke and activate the electric actuator 401 through an electrical signal. The movable rod of the electric actuator 401 moves downward, driving the connected rod 302 to move, thereby opening the sealing plate 301. At the same time, when the movable rod of the electric actuator 401 extends, it will drive the connected rack A403 to move, thereby driving the meshing gear A402 to rotate. Then the gear A402 will drive the connected gear B404 to rotate, and then drive the meshing rack B501 to move, thereby driving the connected fire sprinkler head 5 to move out of the storage base 3.

[0062] At the same time, when the fire sprinkler head 5 moves, the connected opening and closing rack 502 will drive the meshing opening and closing wheel 603 to rotate, which will drive the connected valve plate 602 to open, allowing external water to enter the fire sprinkler head 5 for fire extinguishing.

[0063] The present invention employs a retractable mechanism to allow the fire sprinkler head to be retracted into the storage base when not in use, thereby providing a protective effect for the fire sprinkler head.

[0064] By incorporating a linkage, the sealing plate can be opened and closed simultaneously with the extension and retraction of the fire sprinkler head, automating the device. The retracted fire sprinkler head and closed sealing plate create a seamless, flat surface on the ceiling panel, enhancing its aesthetics and decorative effect. Connecting an opening and closing rack to the fire sprinkler head allows for the connection of the water inlet pipe, enabling external water supply for fire suppression. The connecting mechanism also facilitates the installation and removal of the ceiling panel.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
