Description

Technical Field

[0001] This utility model relates to the field of RV safety equipment technology, specifically a smoke alarm exhaust fan for RVs. Background Technology

[0002] As a special type of vehicle that combines the functions of a house and a car, the enclosed space design and diverse living facilities of a motorhome make fire hazards ever-present. On the one hand, the kitchen stoves, heating equipment, high-power electrical appliances, and complex electrical systems inside the vehicle can easily ignite when used improperly or when the equipment is old. On the other hand, ventilation conditions are limited in motorhome travel scenarios, and some users have a habit of storing flammable items, which further exacerbates the fire risk. When a fire occurs, smoke will fill the entire vehicle at an extremely fast speed, and the smoke concentration will drastically reduce visibility, causing trapped people to lose their way to escape. Moreover, the smoke contains toxic gases such as carbon monoxide and hydrogen cyanide, which not only seriously hinder people's escape opportunities but also pose a direct and imminent threat to their lives.

[0003] Currently, smoke detectors lack precise positioning and efficient fixing devices. Installation often requires various tools and a significant amount of time for debugging and securing, demanding a high level of technical skill from installers. During RV travel, bumps and vibrations can easily cause the equipment to loosen, affecting its normal operation, posing safety hazards, and potentially causing secondary injuries from falling equipment. Furthermore, the lack of effective filtration allows dust, particles, and other impurities in the air to easily enter the exhaust fan and smoke sensor, hindering timely and effective fire hazard warnings. These detectors also cannot adapt to the complex and changing environment of RVs, failing to ensure the safety of the RV and its occupants. Therefore, we propose a smoke alarm exhaust fan for RVs.

[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] Please see Figure 1-6 A smoke alarm exhaust fan for a motorhome includes a smoke alarm housing 1, a mounting plate 2 fixedly mounted on the top of the smoke alarm housing 1, an upper mounting bracket 3 fixedly mounted on the bottom of the smoke alarm housing 1, an electric power source 4 disposed inside the smoke alarm housing 1, an exhaust fan body 5 fixedly mounted at the output end of the electric power source 4, a lower mounting bracket 6 fixedly mounted on the bottom of the upper mounting bracket 3, a connecting bracket 7 fixedly mounted on the bottom of the lower mounting bracket 6, a sensor cover 8 fixedly mounted on the bottom of the connecting bracket 7, a filter screen 9 disposed inside the sensor cover 8, and a mounting mechanism 10 disposed on the top of the mounting plate 2; the mounting mechanism 10 includes a placement device and a clamping device, the placement device placing the smoke alarm body and driving the clamping device to clamp and fix it.

[0027] In this embodiment, the placement device includes a mounting plate 1001, which is disposed on the mounting plate 2. A through hole 1002 is provided on the top of the mounting plate 1001, and a placement plate 1003 is fixedly installed on the bottom of the mounting plate 1001. A limiting plate 1004 is fixedly installed on the outer side of the mounting plate 1001. A first mounting groove 1005 and a second mounting groove 1006 are provided on the outer side of the mounting plate 1001. A threaded hole 1007 is provided inside the mounting plate 1001. The through hole 1002 reduces the weight of the mounting plate 1001 and allows for cable routing during installation, facilitating electrical connections between the smoke alarm body and other components for signal transmission and power supply. The "L"-shaped structure of the placement plate 1003 provides support for the smoke alarm body from the bottom and sides. Combined with multiple limit plates 1004, the smoke alarm body can be precisely positioned to ensure it is centered in the mounting mechanism 10, facilitating subsequent clamping operations. The first mounting slot 1005 and the second mounting slot 1006 provide installation space for the elastic spring 1010 and the snap-fit ​​seat 1014 in the clamping device, respectively, ensuring a tight fit between the clamping device and the placement device to form a complete installation and fixing system.

[0028] Furthermore, the clamping device includes a mounting block 1008, which is disposed on the outer side of the mounting support plate 1001. A limit post 1009 is fixedly mounted on the outer side of the mounting block 1008. An elastic spring 1010 is disposed on the outer side of the limit post 1009. A clamping seat 1011 is disposed on the outer side of the mounting support plate 1001. A rotating handle 1012 is rotatably mounted inside the clamping seat 1011. A snap-fit ​​block 1013 is fixedly mounted on the outer side of the rotating handle 1012. A snap-fit ​​seat 1014 is disposed inside the mounting support plate 1001. A threaded post 1015 is fixedly mounted on the outer side of the snap-fit ​​seat 1014. Positioning is achieved through the limiting plate 1004. The operator rotates the handle 1012, causing the locking block 1013 to rotate. Since the locking block 1013 is compatible with the locking seat 1014, and the threaded hole 1007 and the threaded post 1015 are threadedly connected, the locking block 1013 gradually engages with the locking seat 1014 during rotation, while simultaneously pushing the clamping seat 1011 towards the smoke alarm body. During this process, the elastic spring 1010 is compressed, providing a continuous clamping force to the clamping seat 1011. When the locking block 1013 is fully engaged with the locking seat 1014, the clamping seat 1011 firmly clamps the smoke alarm body, ensuring both ease of installation and stable clamping of the smoke alarm body even in the bumpy and vibrating environment of the RV.

[0029] Furthermore, the vertical cross-section of the placement plate 1003 is L-shaped, and multiple identical sets of limiting plates 1004 are provided, with the bottoms of these limiting plates 1004 aligned with the bottom of the placement plate 1003. This allows the smoke alarm body to be stably placed on the horizontal surface of the placement plate 1003 during installation, while its sides are restrained by the limiting plates 1004, preventing lateral displacement. Simultaneously, because the bottoms of the multiple limiting plates 1004 are flush with the bottom of the placement plate 1003, they provide uniform support from the bottom, preventing the smoke alarm body from tilting during installation. This ensures that the clamping device can accurately and stably fix the smoke alarm, significantly improving installation accuracy and efficiency.

[0030] Furthermore, the elastic spring 1010 is located within the mounting groove 1005. The elastic spring 1010, the mounting support plate 1001, and the clamping seat 1011 are all fixedly connected. The mounting block 1008 is located inside the clamping seat 1011, and the vertical cross-section of the clamping seat 1011 has a "]" shaped structure. The mounting groove 1005 limits and protects the elastic spring 1010, preventing it from shifting or disengaging during operation. The mounting block 1008, located inside the clamping seat 1011, guides and supports the clamping seat 1011 during its movement and clamping process, ensuring smooth movement of the clamping seat 1011 and further improving the reliability of the clamping device.

[0031] In addition, both the snap-fit ​​block 1013 and the snap-fit ​​base 1014 are hexagonal structures, and the snap-fit ​​block 1013 and the snap-fit ​​base 1014 are compatible. The hexagonal snap-fit ​​block 1013 and the snap-fit ​​base 1014 have clear rotational positioning points when engaged, effectively preventing slippage during rotation and ensuring the accuracy of the snap-fit ​​operation. At the same time, the multiple hexagonal faces contact each other, increasing the force-bearing area during snap-fit, making the snap-fit ​​more secure. Even in the complex vibration environment of a motorhome, the snap-fit ​​block 1013 and the snap-fit ​​base 1014 will not easily separate, thus maintaining the stable fixation of the clamping device on the smoke alarm body.

[0032] It is worth noting that the locking seat 1014 is located inside the mounting groove 1006, and the threaded hole 1007 and the threaded post 1015 are threadedly connected. Through the threaded connection between the threaded hole 1007 and the threaded post 1015, the rotating handle 1012 can convert rotational force into linear movement force of the locking seat 1014 when rotating, thereby achieving the engagement and disengagement of the locking block 1013 and the locking seat 1014. This not only makes operation simple but also has good self-locking performance. When the locking block 1013 and the locking seat 1014 are engaged in place, the threaded connection prevents them from loosening due to vibration or other factors, further enhancing the stability and reliability of the clamping device.

[0033] During use, the operator secures the mounting plate 2 to the top of the smoke alarm housing 1 using screws and other connectors to ensure a firm installation that can withstand external forces during subsequent installation and operation. The mounting bracket 3 is then installed at the bottom of the smoke alarm housing 1, again using a suitable fixing method to ensure connection strength. The electric power source 4 is installed inside the smoke alarm housing 1, ensuring proper securing between the electric power source 4 and the housing to prevent shaking during operation. Next, the exhaust fan body 5 is installed at the output end of the electric power source 4, ensuring accurate connection so that the electric power source 4 can stably drive the exhaust fan body 5. The lower mounting bracket 6 is then fixed to the bottom of the upper mounting bracket 3, forming a stable support structure. Finally, the connecting bracket 7 is attached. The bottom of the smoke detector is fitted with a sensor cover 8, and a filter 9 is installed inside the sensor cover 8. The filter 9 can be detached and installed using clips, slots, etc., for easy cleaning and replacement. The mounting plate 1001 is installed on the mounting plate 2. It can be fixed with bolts or other connectors according to the preset mounting holes on the mounting plate 2. The through hole 1002 at the top of the mounting plate 1001 is reserved for cable passage during installation, which facilitates the electrical connection between the smoke detector body and other components. The placement plate 1003 at the bottom of the mounting plate 1001 and the outer limiting plate 1004 are fixed and installed at the factory. Check that their connection is firm to ensure that they will not loosen during subsequent use. The operator fixes the limiting post 1009 on the mounting plate 1001. Install the outer side of the mounting block 1008, then sleeve the elastic spring 1010 on the outer side of the limiting post 1009, and place it into the mounting groove 1005 on the outer side of the mounting support plate 1001, so that both ends of the elastic spring 1010 are fixedly connected to the mounting support plate 1001 and the clamping seat 1011 respectively. Rotate the rotating handle 1012 inside the clamping seat 1011 to ensure flexible rotation. Fix the snap-fit ​​block 1013 on the outer side of the rotating handle 1012. Install the snap-fit ​​seat 1014 in the mounting groove 1006 inside the mounting support plate 1001, and align the threaded post 1015 with the threaded hole 1007. Place the smoke alarm body on the placement plate 1003, and use the placement plate 1003 and multiple sets of limiting plates 1004 for positioning. The bottom of the alarm body is placed on the horizontal surface of the placement plate 1003, and its sides are restricted by the limiting plate 1004 to ensure that it is in the center position of the mounting mechanism 10, preparing for subsequent clamping operations. The operator rotates the handle 1012, causing the locking block 1013 to rotate. Since the locking block 1013 is compatible with the locking seat 1014, and the threaded hole 1007 and the threaded post 1015 are threadedly connected, during rotation, the locking block 1013 gradually engages with the locking seat 1014, while simultaneously pushing the clamping seat 1011 towards the smoke alarm body. During this process, the elastic spring 1010 is compressed, providing a continuous clamping force to the clamping seat 1011. When the locking block 1013 is fully engaged with the locking seat 1014...The handle 1012 can be rotated to firmly clamp the smoke detector body 1011 onto the clamping base. A suitable installation location should be selected inside the RV, typically prioritizing areas with good air circulation and easy smoke monitoring. The assembled smoke alarm exhaust fan is then fixed to the chosen location on the RV using the mounting plate 2. After installation and power-on, the smoke sensor begins real-time monitoring of the smoke concentration inside the RV. Simultaneously, the electric power source 4 drives the exhaust fan body 5 to operate, expelling the smoke outside the vehicle. Users can also manually control the start / stop and operating status of the exhaust fan according to their needs. Regular checks are necessary to ensure the equipment is always in good working order.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
