Description

Technical Field

[0001] This utility model relates to the technical field of building fire protection, specifically to an intelligent window opener with fire smoke extraction function. Background Technology

[0002] In the field of building fire protection, windows are not only important components for ventilation and lighting, but also play a crucial role in smoke extraction during a fire. Traditional window openers mostly rely on manual operation or simple electric control, and cannot automatically respond and perform smoke extraction in the event of a fire, resulting in slow response and inconvenience. While existing intelligent window openers have some automation functions, their level of intelligence in fire smoke extraction is low, and they lack emergency manual operation capabilities in the event of a power outage, making it difficult to meet the higher fire safety requirements of modern buildings. In addition, traditional window openers are prone to wear and tear on mechanical parts due to dust accumulation during long-term use, affecting their stability and service life. Therefore, developing an intelligent window opener that combines automatic smoke extraction, manual emergency operation, and dust prevention functions has significant practical significance and application value.

[0003] A search revealed Chinese patent publication number CN220336718U, which discloses a smart window opener with fire-fighting smoke extraction function. The opener includes a housing, an opening and closing mechanism, and a cover plate. The opening and closing mechanism is located on the housing, and the cover plate is located at the front end of the housing. The mechanism includes a slide groove, a motor, a reducer, a worm gear, a screw, a worm wheel, a slider, a pull rod, and a connector. The motor is located at the bottom inside the housing. The reducer is located on the inner wall of the housing and connected to the motor above it. One end of the worm gear is attached to the reducer, and the other end is rotatably connected to the top inside the housing. The screw is rotatably connected to the inner wall of the housing and passes through the slide groove. The worm wheel is attached to the screw and meshes with the worm gear. This invention belongs to the field of smart window opener technology, specifically a widely applicable and multifunctional smart window opener with fire-fighting smoke extraction function.

[0004] However, while it possesses basic window-opening functionality, its design has significant shortcomings, particularly in terms of automatic and manual dual-mode operation. The device relies solely on a motor to drive a worm gear and worm wheel to open and close the window, lacking a manual operation mechanism. In the event of a power outage or motor malfunction, the device will be unable to open the window properly, failing to meet emergency needs in situations such as fires. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an intelligent window opener with fire smoke extraction function, solving the problems of existing devices lacking dual-mode operation and effective dustproof design.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent window opener with fire smoke extraction function, comprising a housing, a rotating device, and a slider. The housing is equipped with the rotating device, the rotating device is equipped with the slider, and the rotating device is equipped with a mounting frame. A rotating motor is fixedly connected to the mounting frame, the output shaft of the rotating motor is connected to a limiting wheel, and the limiting wheel is connected to a first rotating rod. The first rotating rod is equipped with a first driving gear and a second driving gear. A second rotating rod is fixedly connected to one side of the mounting frame, and a handle is provided at one end of the second rotating rod. In use, pulling the handle causes the limiting wheel's outer wall to embed into a through groove in the housing, where the roller assembly assists in the rotation of the limiting wheel. The second driving gear meshes with the second driven gear, and rotating the handle opens the window.

[0007] When in use, the device is installed at the top of the window and the mounting block is connected to the window frame. In the event of a fire, the smoke sensor transmits an electrical signal to the control module. The control module drives the rotating motor to rotate, which in turn causes the limit wheel and the first rotating rod to rotate. This causes the first driving gear to rotate, and the lead screw follows the rotation of the first driven gear, causing the slider to move. The movement of the slider causes the connecting rod to gradually move towards the direction perpendicular to the smoke sensor, thereby opening the window. However, in the event of a fire, there is often a risk of power outages. At this time, pulling the handle will cause the insert on the mounting bracket to be pulled out of the groove in the housing. When the outer wall of the limit wheel is embedded in the through groove of the housing, the second driving gear and the second driven gear mesh. Since the gear combination torque of the second driven gear and the second driving gear 13 is relatively small, rotating the handle can quickly open the window.

[0008] Preferably, the housing is provided with a lead screw, the lead screw is provided with a first driven gear and a second driven gear, the first driven gear meshes with a first driving gear, the second driven gear meshes with a second driving gear, and the gear combination of the second driven gear and the second driving gear has a smaller torque than the combination of the first driven gear and the first driven gear.

[0009] Preferably, the lead screw is connected to the slider via a threaded seat, and the thread of the lead screw engages with the thread of the threaded seat.

[0010] Preferably, the housing is equipped with a guide rail, the guide rail is equipped with a slider, the slider is equipped with a connecting rod, the connecting rod is equipped with a mounting block, the housing is equipped with a smoke sensor, the housing is equipped with a control module, the slider is equipped with a through hole, the cross-section of which is the same as that of the guide rail, which limits the movement of the slider, and since it is located inside the housing, it can play a dustproof role, ensure the normal operation of the device, and increase the service life of the device. The cross-section of the through hole is the same as that of the limiting wheel and can be fitted together.

[0011] Preferably, the mounting bracket is equipped with a spring, which is fixedly connected to one end of the insert block. The insert block has a trapezoidal design, and a matching groove is provided on one side of the housing. The trapezoidal design of the insert block facilitates its insertion and removal.

[0012] Preferably, a through groove is provided on one side of the housing, and a roller assembly is provided in the through groove. The roller assembly can assist the rotation of the first rotating rod when it is manually rotated.

[0013] This utility model provides an intelligent window opener with fire smoke extraction function. It has the following features:

[0014] Beneficial effects:

[0015] 1. This intelligent window opener with fire smoke extraction function combines automatic and manual operation functions in its rotating device design, adapting to various usage scenarios. Under normal circumstances, the device detects fire signals through a smoke sensor, and the control module drives the rotating motor to rotate the limit wheel and the first rotating rod. In turn, the first driving gear and the first driven gear drive the screw to rotate, pushing the slider to move and realize the automatic opening of the window. In emergency situations such as power failure or motor failure, the user can pull the handle to unlock the overall rotation capability of the rotating device, so that the second driving gear and the second driven gear mesh. Since the torque of this gear set is small, the user can easily rotate the handle to manually drive the screw to rotate and quickly open the window. This dual-mode design ensures the reliability of the device in emergency situations such as fire, while also taking into account the convenience of daily use.

[0016] 2. This intelligent window opener with fire smoke extraction function uses a semi-enclosed design of the housing. The slider has a through hole with the same cross-section as the guide rail. The slider and guide rail prevent dust and other particles from directly entering the housing, protecting the normal operation of the gears and control module, and extending their service life.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-6 This utility model provides a smart window opener with fire smoke extraction function, including a housing 3, a rotating device 4, and a slider 2. The housing 3 is equipped with the rotating device 4, the rotating device 4 is equipped with the slider 2, and the rotating device 4 is equipped with a mounting frame 17. The mounting frame 17 is fixedly connected to a rotating motor 16. The output shaft of the rotating motor 16 is connected to a limiting wheel 11, and the limiting wheel 11 is connected to a first rotating rod 12. The first rotating rod 12 is equipped with a first driving gear 14 and a second driving gear 13. A second rotating rod 18 is fixedly connected to one side of the mounting frame 17. One end of the second rotating rod 18 is equipped with a handle 19. The output shaft of the rotating motor 16 is connected to the limiting wheel 11, and the limiting wheel 11 drives the first driving gear 14 and the second driving gear 13 through the first rotating rod 12.

[0028] Example 2

[0029] Please see Figure 1-6In this embodiment, the housing 3 is provided with a lead screw 8, which is equipped with a first driven gear 9 and a second driven gear 10. The first driven gear 9 meshes with the first driving gear 14, and the second driven gear 10 meshes with the second driving gear 13. The gear combination of the first driven gear 9 and the first driving gear 14 is designed for high torque transmission, which is suitable for motor drive. The gear combination of the second driven gear 10 and the second driving gear 13 is designed for low torque transmission, which is suitable for manual operation. The dual gear combination design ensures efficient power transmission in both motor drive and manual operation.

[0030] The lead screw 8 is connected to the slider 2 via a threaded seat. When the lead screw 8 rotates, the linear motion of the threaded seat drives the slider 2 to move along the guide rail 1, which can ensure the smooth movement of the slider 2, with high precision and high stability, thereby realizing the precise opening and closing of the window.

[0031] The housing 3 is equipped with a guide rail 1, a slider 2, a connecting rod 7, and a mounting block 6. The housing 3 is also equipped with a smoke sensor 5 and a control module 15. The smoke sensor 5 is used to detect fire signals, and the control module 15 is used to receive signals and control the operation of the rotating motor 16.

[0032] Mounting bracket 17 is equipped with spring 23, which is fixedly connected to one end of insert block 22. When manual operation is required, pulling handle 19 can pull insert block 22 out of groove and rotate device 4 to unlock its rotation capability.

[0033] A through groove 21 is provided on one side of the housing 3, and a roller assembly 20 is provided in the through groove 21. The roller assembly 20 is used to assist the rotation of the first rotating rod 12 during manual operation, reduce frictional resistance, and make manual operation more labor-saving. The design of the roller assembly 20 improves the convenience of manual operation.

[0034] It should be noted that in this embodiment, when the device is in use, the housing 3 is installed on the top of the window and the mounting block 6 is connected to the window frame. When a fire occurs, the smoke sensor 5 transmits an electrical signal to the control module 15. The control module 15 drives the rotating motor 16 to rotate, which in turn drives the limit wheel 11 and the first rotating rod 12 to rotate. This causes the first driving gear 14 to drive the first driven gear 9 to rotate. The lead screw 8 follows the rotation of the first driven gear 9, which drives the slider 2 to move. The movement of the slider 2 causes the connecting rod 7 to gradually move towards the direction perpendicular to the smoke sensor 5, thereby opening the window. However, fires are often accompanied by power outages. At this time, the user can pull the handle 19 to pull the insert 22 on the mounting bracket 17 out of the groove in the housing 3. When the outer wall of the limit wheel 11 is embedded in the through groove 21 of the housing 3, the second driving gear 13 meshes with the second driven gear 10. Since the gear combination torque of the second driven gear 10 and the second driving gear 13 is small, rotating the handle 19 can quickly open the window.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
