Description

Technical Field

[0001] This utility model relates to the field of smoke alarm technology, specifically a fire smoke alarm device. Background Technology

[0002] In the field of modern fire safety, smoke alarm devices are crucial for protecting life and property. Currently, some smoke alarm devices on the market use 3M adhesive to attach a magnet to the top of the alarm, and then another magnet is attached to the roof using 3M adhesive, utilizing the magnetic force between the two magnets to install the smoke alarm. However, this installation method has many drawbacks.

[0003] First, the adhesive strength of 3M adhesive is significantly affected by environmental factors. In high-temperature environments, the adhesive strength decreases, leading to weak adhesion between the magnet and the alarm, and between the magnet and the ceiling, making the smoke alarm device prone to detachment. For example, in hot indoor environments during summer, especially in areas with direct sunlight, temperatures can reach 35°C or even higher, at which point the adhesive strength of 3M adhesive will be significantly weakened. In humid environments, moisture can seep into the contact surface between the 3M adhesive and the object, damaging its adhesive structure and also causing the magnet to detach. During the rainy season in southern China, when air humidity remains consistently high, smoke alarm devices installed using this method frequently fall off.

[0004] Secondly, the adhesion of 3M adhesive decreases over time. After prolonged use, 3M adhesive gradually ages and loses its original stickiness. Smoke alarm devices, as equipment that operates for extended periods, typically need to maintain a stable installation for a considerable time. However, once the 3M adhesive ages, even under normal environmental conditions, it may be difficult to ensure a stable installation of the smoke alarm device, potentially leading to accidental fall and affecting its timely smoke monitoring and alarm functions.

[0005] Furthermore, the installation method using dual magnets for magnetic adsorption is prone to displacement or even detachment when subjected to external impacts or vibrations due to the limited attractive force between the magnets. For example, in scenarios such as home renovations and furniture moving, some vibration and collisions are unavoidable. This could cause the smoke alarm device, which relies on magnetic adsorption, to change position or fall off, rendering it ineffective in its monitoring function.

[0006] Therefore, it is necessary to redesign and modify the fire smoke alarm device to effectively prevent it from falling and being damaged due to insecure installation, which would lead to waste of resources and reduced environmental friendliness. Utility Model Content

[0007] To address the problems mentioned in the background art, the purpose of this utility model is to provide a fire smoke alarm device that has the advantages of secure installation and easy disassembly.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a fire smoke alarm device, comprising a sleeve, a fixed rod fixedly connected to the inner wall of the sleeve, the fixed rod being a plurality of rods evenly distributed in a ring on the inner wall of the sleeve, a cylindrical block slidably connected to the inner wall of the sleeve, a limiting groove being provided on the surface of the cylindrical block, the limiting groove being a plurality of rods evenly distributed in a ring on the surface of the cylindrical block, the fixed rods being slidably connected to the limiting grooves, a smoke alarm body being fixedly connected to the top of the cylindrical block, and an elastic component being provided at the bottom of the inner wall of the sleeve.

[0009] In a preferred embodiment of this invention, the elastic component includes a spring fixedly connected to the bottom of the inner wall of the sleeve, and a pressure block fixedly connected to the top of the spring, the pressure block being in contact with the cylindrical block.

[0010] As a preferred embodiment of this utility model, a support column is fixedly connected to the bottom of the inner wall of the sleeve. The number of support columns is several, and the support columns are evenly distributed in a ring at the bottom of the inner wall of the sleeve. A groove is provided at the top of the support column, and a movable column is slidably connected inside the groove. The top of the movable column is fixedly connected to the bottom of the pressure block.

[0011] As a preferred embodiment of this utility model, a protective frame is fixedly connected to the surface of the sleeve. The number of protective frames is several, and the protective frames are evenly distributed in a ring on the surface of the sleeve. The protective frames are L-shaped.

[0012] As a preferred embodiment of this utility model, the bottom of the sleeve is fixedly connected to a mounting plate, and the surface of the mounting plate is provided with mounting openings. The number of mounting openings is several, and the mounting openings are evenly distributed in a ring on the surface of the mounting plate.

[0013] As a preferred embodiment of this invention, the surface of the spring is coated with anti-rust paint, and the top of the pressure block and the bottom of the cylindrical block are both smooth.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model abandons the traditional installation method that relies on 3M adhesive and magnetic adsorption. Instead, it uses a mounting plate and bolts for roof fixation. Multiple bolts significantly improve the stability of the mounting plate, thus ensuring the secure installation of the sleeve, fixing rod, cylindrical block, and smoke alarm body. Simultaneously, the unique cooperation between the fixing rod and the limiting groove on the cylindrical block surface, combined with the upward force applied by the elastic component, prevents the smoke alarm body from loosening or falling off due to external impacts, vibrations, or environmental changes after installation. This effectively ensures the stable operation of the device during long-term use, providing reliable protection for fire safety monitoring. The device has an ingenious structural design. When maintenance or replacement of the smoke alarm body is required, simply align the inlet of the limiting groove on the cylindrical block surface with the fixing rod, and easily separate the smoke alarm body from the cylindrical block by moving it upwards and rotating it. The disassembly and assembly process does not require complex tools, greatly improving operational convenience and facilitating rapid maintenance later, saving manpower and time costs. This device has the advantages of secure installation and easy disassembly.

[0016] 2. By setting up an elastic component, the spring applies elastic force to the pressure block, making the pressure block and the cylindrical block fit tightly together, thereby applying an upward force to the cylindrical block and the smoke alarm body.

[0017] 3. By effectively fixing the smoke alarm body and providing a certain degree of protection for the smoke alarm body through a protective frame, this utility model can reduce the probability of damage to the smoke alarm body, thereby avoiding waste of resources and achieving the goal of environmental protection to a certain extent.

[0024] 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.

[0025] like Figures 1 to 5 As shown, a fire smoke alarm device includes a sleeve 1. A number of fixing rods 2 are fixedly connected to the inner wall of the sleeve 1. The fixing rods 2 are evenly distributed in a ring on the inner wall of the sleeve 1. A cylindrical block 3 is slidably connected to the inner wall of the sleeve 1. A number of limiting grooves 4 are provided on the surface of the cylindrical block 3. The limiting grooves 4 are evenly distributed in a ring on the surface of the cylindrical block 3. The fixing rods 2 are slidably connected to the limiting grooves 4. A smoke alarm body 5 is fixedly connected to the top of the cylindrical block 3. An elastic component 6 is provided at the bottom of the inner wall of the sleeve 1.

[0026] refer to Figure 2 The elastic component 6 includes a spring 7 fixedly connected to the bottom of the inner wall of the sleeve 1, and a pressure block 8 fixedly connected to the top of the spring 7, which is in contact with the cylindrical block 3.

[0027] As a technical optimization of this utility model, by setting the elastic component 6, the spring 7 applies elastic force to the pressure block 8, so that the pressure block 8 is in close contact with the cylindrical block 3, thereby applying an upward force to the cylindrical block 3 and the smoke alarm body 5.

[0028] refer to Figure 2 A support column 9 is fixedly connected to the bottom of the inner wall of the sleeve 1. There are several support columns 9. The support columns 9 are evenly distributed in a ring at the bottom of the inner wall of the sleeve 1. The top of the support column 9 is provided with a groove, and a movable column 10 is slidably connected inside the groove. The top of the movable column 10 is fixedly connected to the bottom of the pressure block 8.

[0029] As a technical optimization of this utility model, by setting up the support column 9, the groove and the movable column 10, the movable column 10 slides up and down in the groove, thereby ensuring that the pressure block 8 can slide up and down stably.

[0030] refer to Figure 1 A protective frame 13 is fixedly connected to the surface of the sleeve 1. There are several protective frames 13, which are evenly distributed in a ring on the surface of the sleeve 1. The protective frame 13 is L-shaped.

[0031] As a technical optimization of this utility model, the protective frame 13 can prevent the smoke alarm body 5 from being damaged by collision when moving furniture, thereby improving the protection effect of the smoke alarm body 5 to a certain extent, and will not affect the normal operation of the smoke alarm body 5.

[0032] refer to Figure 1 The bottom of the sleeve 1 is fixedly connected to the mounting plate 11. The surface of the mounting plate 11 is provided with mounting ports 12. There are several mounting ports 12, which are evenly distributed in a ring on the surface of the mounting plate 11.

[0033] As a technical optimization of this utility model, by setting up the mounting plate 11 and the mounting port 12, the operator can install the mounting plate 11 to the roof with bolts and fix the mounting plate 11 with multiple bolts, thereby improving the stability of fixing the mounting plate 11, and thus improving the stability of fixing the sleeve 1, the fixing rod 2, the cylindrical block 3 and the smoke alarm body 5.

[0034] refer to Figure 2 The surface of the spring 7 is coated with anti-rust paint, and the top of the pressure block 8 and the bottom of the cylindrical block 3 are both smooth.

[0035] As a technical optimization of this utility model, by spraying anti-rust paint on the surface of the spring 7, the spring 7 can be prevented from being corroded, thereby extending the service life of the device. By making the top of the pressure block 8 and the bottom of the cylindrical block 3 smooth, the friction between the pressure block 8 and the cylindrical block 3 can be reduced, thereby facilitating the relative sliding of the pressure block 8 and the cylindrical block 3.

[0036] The working principle and usage process of this utility model are as follows: When the operator needs to install the smoke alarm body 5, the operator first installs the mounting plate 11 on the roof with bolts, and then installs the sleeve 1, the fixing rod 2 and the elastic component 6. Then, the operator holds the smoke alarm body 5 and aligns the entrance of the limiting groove 4 on the surface of the cylindrical block 3 with the fixing rod 2. Then, the cylindrical block 3 is moved upward. At this time, the spring 7 is compressed. When the fixing rod 2 moves to the first corner in the limiting groove 4, the operator rotates the smoke alarm body 5 and the cylindrical block 3, so that the fixing rod 2 moves to the second corner in the limiting groove 4. Then, the operator releases the smoke alarm body 5. Under the action of the spring 7, the spring 7 pushes the pressure block 8 downward, which in turn drives the cylindrical block 3 and the smoke alarm body 5 downward. At this time, the fixing rod 2 contacts the bottom of the channel of the limiting groove 4, and the installation of the smoke alarm body 5 is completed.

[0037] This device has a simple structure. When it is necessary to maintain or replace the smoke alarm body 5, the operator can quickly disassemble and assemble the smoke alarm body 5 and the cylindrical block 3, thereby achieving the purpose of quick disassembly and assembly, which improves the ease of operation of this device. At the same time, by effectively fixing the smoke alarm body 5 and by providing a certain degree of protection to the smoke alarm body 5 through the protective frame 13, this device can reduce the probability of damage to the smoke alarm body 5, thereby avoiding waste of resources and achieving the purpose of environmental protection to a certain extent.

[0038] The smoke alarm body 5 described above utilizes the principle of light scattering to detect smoke generated in the early stages of a fire. The alarm contains a light-emitting element and a light receiver. Under normal circumstances, the light emitted by the light-emitting element does not directly illuminate the light receiver. When smoke enters the alarm, the particles in the smoke scatter the light, and some of the scattered light is directed to the light receiver. The light receiver receives the light signal and converts it into an electrical signal, triggering the alarm device to sound an alarm. The smoke alarm body 5 described above is a common existing technology and is common knowledge to those skilled in the art; therefore, it will not be described in detail here.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
