[0002] In modern life, wall-mounted intelligent smoke detectors are widely used in homes, offices, warehouses and other places as an important safety device to monitor the concentration of smoke in the air, detect fire hazards in time, and protect people's lives and property.

[0003] Traditional smoke detectors typically feature a fixed filter cartridge structure to prevent larger impurities in the smoke from entering the detector's interior. However, the filter pore size is usually fixed, which has limitations. This design can lead to insufficient sensitivity or false alarms in certain scenarios. For example, in kitchens or other places where oil fumes are easily generated but false alarms are undesirable, traditional smoke detectors may not be able to detect the small oil fume particles in time, resulting in reduced timeliness and accuracy of the alarm. In warehouses or other places where large amounts of dust or smoke are stored, the interference from dust or smoke can easily cause false alarms, causing unnecessary inconvenience to users.

[0004] Therefore, this application provides a wall-mounted intelligent smoke alarm to solve the above problems. Utility Model Content

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Example 1

[0030] This embodiment provides a wall-mounted intelligent smoke detector, such as... Figures 1-2 As shown, the wall-mounted intelligent smoke alarm includes a base 1, a body 2 fixedly mounted on the base 1, a smoke inlet 3 located on the side of the body 2 away from the base 1, an upper seat 4 fixedly mounted on the body 2 above the smoke inlet 3, and a fixed filter cartridge 5 whose two ends are fixedly connected to the smoke inlet 3 and the bottom of the upper seat 4 respectively. The wall-mounted intelligent smoke alarm also includes an adjustment mechanism 6 mounted on the upper seat 4 for adjusting the size of the filter holes on the fixed filter cartridge 5. The adjustment mechanism 6 includes a movable filter cartridge 61 rotatably mounted inside the fixed filter cartridge 5 and connected to the upper seat 4, a drive assembly 62 mounted inside the upper seat 4 for rotating the movable filter cartridge 61, and a connector 63 mounted on the drive assembly 62 and the movable filter cartridge 61 for assembling and disassembling the drive assembly 62 and the movable filter cartridge 61.

[0031] In order to facilitate the installation of the drive component 62, the upper seat 4 is provided with a receiving cavity 41 at the position corresponding to the drive component 62; the design of the receiving cavity 41 provides a dedicated installation space for the drive component 62, making the whole structure more compact.

[0032] When smoke is generated indoors, it enters the body 2 through the smoke inlet 3. During this process, the smoke is first filtered by the filter holes on the fixed filter cartridge 5 to remove larger particles or impurities, preventing them from entering the body 2 and affecting its operation. However, when the body 2 is installed to detect smoke, the user can operate the drive component 62 to rotate the movable filter cartridge 61 according to the installation requirements. This changes the superposition effect of the filter holes on the movable filter cartridge 61 and the fixed filter cartridge 5, thereby adjusting the size of the smoke particles passing through the fixed filter cartridge 5. In situations where the alarm sensitivity needs to be increased, such as in kitchens or other places where oil fumes are easily generated but false alarms are not desired, the filter holes on the movable filter cartridge 61 can be enlarged to allow smaller smoke particles to pass through and enter the detector's sensing range. Conversely, in situations where the sensitivity needs to be reduced, such as in warehouses storing large amounts of dust or smoke, the filter holes on the movable filter cartridge 61 can be reduced. Furthermore, the movable filter cartridge 61 can be periodically deactivated by operating the connector 63 to loosen the fixation between the movable filter cartridge 61 and the drive component 62 and to perform maintenance on the movable filter cartridge 61.

[0033] Specifically, the drive assembly 62 includes a gear ring 621 rotatably connected to the receiving cavity 41 and connected to the outside of the movable filter cartridge 61, a connecting shaft 623 rotatably connected to one side of the gear ring 621 in the receiving cavity 41, and a gear 622 fixedly connected to the connecting shaft 623 and meshing with the gear ring 621.

[0034] When the user needs to adjust the size of the filter holes on the fixed filter cartridge 5 according to the installation requirements, the connecting shaft 623 can be rotated. As the connecting shaft 623 rotates, the gear 622 connected to it will also rotate synchronously. Since the gear 622 meshes with the gear ring 621, and the gear ring 621 is connected to the movable filter cartridge 61, the rotation of the gear 622 will cause the gear ring 621 to drive the movable filter cartridge 61 to rotate together. As the movable filter cartridge 61 rotates, it will change the superposition effect of the filter holes on it and the filter holes on the fixed filter cartridge 5, thereby realizing the adjustment of the size of the filter holes on the fixed filter cartridge 5 to meet different usage requirements.

[0035] It should be added that the rotation of the connecting shaft 623 can be driven manually by a knob or automatically by a motor.

[0036] Furthermore, the connector 63 includes a connecting plate 631 arranged in a ring array on the toothed ring 621 and located outside the movable filter cartridge 61, and fastening bolts 632 provided at both ends of the connecting plate 631. The two ends of the connecting plate 631 are respectively fixedly connected to the connecting plate 631 and the movable filter cartridge 61 by two fastening bolts 632.

[0037] When the movable filter cartridge 61 needs to be maintained regularly, the connection between the fastening bolts 632 at both ends of the connecting plate 631 and the movable filter cartridge 61 and the toothed ring 621 can be released by loosening the fastening bolts 632. The movable filter cartridge 61 can then be removed from the toothed ring 621 for maintenance or replacement. When the movable filter cartridge 61 needs to be installed, the connecting plate 631 is placed in the required position, and the movable filter cartridge 61 and the toothed ring 621 are fixed by tightening the fastening bolts 632. Furthermore, since the toothed ring 621 rotates within the receiving cavity 41, the toothed ring 621 will not detach from the connection of the receiving cavity 41 when the movable filter cartridge 61 and the toothed ring 621 are disassembled.

[0038] In addition, to further facilitate the disassembly and assembly of the movable filter cartridge 61, the upper seat 4 is provided with a through hole 42 at the position corresponding to the movable filter cartridge 61 for the movable filter cartridge 61 to pass through; through the through hole 42, the user can easily remove the disassembled movable filter cartridge 61 from the upper seat 4 for cleaning or replacement, and insert the movable filter cartridge 61 into the upper seat 4 and install it with the toothed ring 621, further simplifying the disassembly and assembly process.

[0039] Understandably, in order to ensure the use of the adjustment mechanism 6, a sealing cover 43 is screwed onto the side of the upper seat 4 away from the through hole 42. The design of the sealing cover 43 is such that, during the use of the alarm, the sealing cover 43 can be tightened to seal the upper seat 4, preventing external dust, moisture and other impurities from entering the alarm from the upper seat 4 and thus affecting the use of the adjustment mechanism 6. At the same time, when maintenance or operation of the adjustment mechanism 6 is required, simply loosen the sealing cover 43 and open the upper seat 4.

[0040] Example 2

[0041] Unlike Embodiment 1, in order to further facilitate the installation of the movable filter cartridge 61, such as Figure 3 As shown, a positioning groove 51 is provided at the bottom inner side of the fixed filter cylinder 5, and a positioning ring 611 is fixedly provided at the end of the movable filter cylinder 61 away from the toothed ring 621. The positioning ring 611 is movably disposed in the positioning groove 51. When it is necessary to install the movable filter cylinder 61, first insert the positioning ring 611 on the movable filter cylinder 61 into the corresponding positioning groove 51 on the fixed filter cylinder 5. Through the positioning and guidance of the positioning ring 611 and the positioning groove 51, the movable filter cylinder 61 is fixed to the toothed ring 621 using the connector 63, and the installation of the movable filter cylinder 61 can be completed.

[0042] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
