[0002] With the increasing security needs of modern families, home fire safety cameras have become an important security device. They not only monitor the home environment in real time but also issue timely alarms in the event of a fire, buying precious escape time for family members.

[0003] Home fire safety cameras are indispensable security devices for modern families. Through real-time monitoring, intelligent detection, and remote alarm functions, they can effectively prevent and respond to fires, protecting the lives and property of family members. According to the authorized announcement number "CN218830325U", a protective device for a home fire alarm camera is disclosed, including a storage tube and a first fixing ring. The first fixing ring is fixedly installed on the back side wall of the storage tube. A fixing groove is opened inside the storage tube, and a second fixing ring is fixedly installed inside the fixing groove. A protective shielding device is set inside the second fixing ring. The protective shielding device includes a collar, with a fixing block fixedly installed at the center inside the collar. Torque springs are fixedly installed at both ends of the fixing block inside the collar, and an inner fixing strip is fixedly installed at the end of the torque spring away from the fixing block. This protective device for a home fire alarm camera, by setting up a protective shielding device, can retract the fire alarm camera into the storage tube in the event of flame exposure, reducing the direct damage to the fire alarm camera caused by direct flame exposure, improving the protection of the fire alarm camera in small and medium-sized fires, and reducing user costs.

[0004] Currently, the main fire safety hazard in homes is fire, especially in the kitchen where there is an open flame, which is a high-frequency area for fires. Many fires are caused by people forgetting to cook on the gas stove or using the gas stove improperly when they are in a hurry. In order to monitor and sense fire situations in a timely manner, cameras can be used for monitoring. However, conventional cameras can only record live video and have poor ability to report fires in other surrounding areas. At the same time, when using cameras for a long time, the wiring also needs to be protected to prevent the wiring from being dragged and damaged. Utility Model Content

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figures 1-5 A protective device for a home fire alarm camera includes a camera body 1. The camera body 1 includes a base 11 and a housing 12. The base 11 and the housing 12 are fixed to each other by screws. Both the base 11 and the housing 12 are made of high-strength plastic material. A shooting port 13 is provided at the bottom of the housing 12. The base 11 and the housing 12, made of high-strength plastic material, have good corrosion resistance, dustproof and moisture-proof capabilities during normal use. The shooting port 13 can provide a shooting area for the camera shooting components.

[0027] One end of the side wall of the outer casing 12 is wrapped with a connecting seat 17, which is a semi-circular ring structure. The monitoring component 14 is embedded and fixed in the middle area of ​​the connecting seat 17. The monitoring component 14 includes a gas sensor 141, a smoke sensor 142, and a temperature sensor 143. The monitoring component 14 also has a processor, a wireless signal transmitter, and an alarm installed inside. When the gas sensor 141, smoke sensor 142, and temperature sensor 143 are monitoring and issuing warnings, the data collected by the sensors is processed and analyzed by the built-in microprocessor. The microprocessor determines whether the alarm conditions are met according to the preset threshold. When the detected gas concentration, smoke concentration, or temperature exceeds the preset threshold, the microprocessor triggers the alarm. The alarm can be issued on-site by means of sound, light, etc. The alarm information can be sent to the user's mobile phone or computer through the wireless signal transmitter in conjunction with Wi-Fi or cellular network. The user can receive the alarm information and view the real-time monitoring screen through a dedicated application.

[0028] Mounting brackets 15 are symmetrically fixed on the top of the base 11. The mounting brackets 15 have an L-shaped structure and mounting holes 16 that penetrate through the horizontal position of the mounting brackets 15. The entire camera assembly can be installed on the roof by using the mounting holes 16 and screws.

[0029] It should be further noted that threaded posts 2 are fixedly installed on both sides of the outer shell 12 by brackets, and collars 21 are fixedly installed on both ends of the connecting seat 17 by brackets. The threaded posts 2 and collars 21 are slidably connected through each other. The connection between the threaded posts 2 and collars 21 facilitates quick positioning and docking between the connecting seat 17 and the outer shell 12.

[0030] It should be further noted that a threaded cap 22 is threadedly installed at the end of the threaded column 2. One side of the threaded cap 22 is slidably and tightly attached to the end face of the threaded column 2. The threaded cap 22 and the threaded column 2 are threadedly installed to each other, which facilitates the assembly and fixing of the connecting seat 17 and the outer shell 12.

[0031] It should be further noted that a positioning plate 3 is fixedly installed at the end of the outer shell 12 away from the monitoring component 14. A winding post 31 is fixedly installed on the surface of the positioning plate 3. The winding post 31 can wind and roll up the excess length of the wire connected to the camera body 1 to reduce the occurrence of falling and bending, and avoid the wire from being damaged due to being kept in a bent state for a long time.

[0032] It should be further explained that the surface of the winding post 31 is covered with a tightening cap 32. A pull head 33 is fixedly installed on the side of the tightening cap 32 away from the positioning plate 3. After the tightening cap 32 covers the winding post 31, it can wrap and tighten the wire wound on the winding post 31 to prevent it from becoming loose.

[0033] It should be further noted that the end face of the winding post 31 is provided with a slot 34, and an elastic clip 35 is fixedly installed on the inner wall of the tightening cap 32. The surface of the elastic clip 35 and the groove of the slot 34 are engaged with each other. The shape of the elastic clip 35 and the shape of the groove of the slot 34 are both regular hexagons, and the elastic clip 35 is made of rubber material.

[0034] It should be further explained that the surface of the tightening cap 32 is provided with a number of notches 36. The notches 36 are distributed equidistantly in a ring along the surface of the tightening cap 32, and at least two notches 36 are provided. This can facilitate the stability of the wire entering and exiting at the position of the tightening cap 32 when the wire is wound on the winding post 31.

[0035] In practice

[0036] The multi-sensor combination in the monitoring component 14 of this solution involves gas sensor 141, smoke sensor 142, and temperature sensor 143 monitoring the concentration of combustible gas, smoke particle density, and ambient temperature in the environment in real time, respectively. The data collected by the sensors is analyzed in real time by the built-in microprocessor. By comparing it with preset safety thresholds, it determines whether to trigger an alarm. For example, when the smoke concentration exceeds the threshold, the microprocessor will simultaneously activate the on-site audible and visual alarm and push the alarm information to the user's terminal device, mobile phone or computer, via a wireless signal transmitter such as Wi-Fi or cellular network. Users can view the real-time monitoring screen through a dedicated application to achieve remote early warning. This design, which combines multimodal sensing and intelligent analysis, significantly improves the early identification capability of fires or gas leaks while reducing the false alarm rate.

[0037] The housing 12 is fixed to the base 11 with screws, while the monitoring component 14 is embedded in the side wall of the housing through the semi-circular ring connector 17. The two ends of the connector are slidably connected to the threaded post 2 through the collar 21, and finally locked with the threaded cap 22. This design not only ensures the stability of the monitoring component, but also simplifies the disassembly process, making it easy to replace the sensor or repair the internal circuit. In addition, the L-shaped structure of the mounting bracket 15 and the mounting hole 16 support the quick fixing of the roof, while the winding post 31 and tightening cap 32 on the positioning plate 3 optimize the line management and avoid cable bending damage. Modular assembly significantly reduces maintenance costs and extends the service life of the equipment.

[0038] The winding post 31 and tightening cap 32 achieve efficient cable storage and protection. Excess cable can be wound around the winding post, and the tightening cap is fixed by the hexagonal snap-fit ​​of the elastic clip 35 and the slot 34 to ensure that the cable bundle is tightly wrapped. The notch 36 design allows the cable to maintain a natural bend when entering and exiting, avoiding damage to the insulation layer caused by right-angle bending.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
