Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to a camera with smoke warning function. Background Technology

[0002] In the existing technology, devices that combine video recording and smoke warning functions have many shortcomings. In terms of installation and fixation, some camera installation structures are not stable enough, and are only fixed by simple clips or screws. They are easily shaken or even fall off due to external forces, affecting normal use. Moreover, the installation and disassembly process is cumbersome, which brings inconvenience to later maintenance and position adjustment. In terms of functional protection and operating environment, the ventilation structure of some devices is not reasonably designed and lacks effective foreign object blocking components. External dust, insects and other foreign objects can easily enter the device, causing component damage and shortening the service life of the device. Regarding smoke detection, traditional devices have low sensitivity, relying mainly on natural airflow to bring smoke into the sensing area, resulting in slow response and difficulty in quickly detecting smoke. The conversion and transmission mechanisms of smoke signals are not perfect, often leading to signal delays or distortions. The warning methods are limited, relying on either sound or light for alerts, which may not attract the attention of people in complex environments, resulting in poor warning effectiveness. In addition, many devices lack emergency power supply mechanisms, and once a power outage occurs, the smoke detection function will fail, rendering it ineffective in emergency situations and posing a significant safety hazard.

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

[0015] Example: See Figure 1-5 This utility model discloses a camera with smoke warning function, including a camera housing 1, which is snapped onto one end of a camera sleeve 2. A camera mechanism is installed inside the camera housing 1 and inside the camera sleeve 2. The inside of the camera sleeve 2 is divided into two layers by a circular plate, and multiple ventilation openings 3 are equidistantly provided on the outside of the camera sleeve 2. Multiple vertical baffles are equidistantly provided in the ventilation openings 3 to prevent foreign objects from entering the device and damaging it. A thread is provided on the inner wall of one end of the camera sleeve 2, and the camera sleeve 2 is connected to the base plate 4 by the thread. A fixing hole is provided in the middle of the base plate 4, and the inside of the fixing hole is fixed to the wall by an expansion bolt 5. One end of the expansion bolt 5 is fixed to the wall by a fixing nut 12. The expansion bolt 5 and the fixing nut 12 facilitate the stable fixing of the camera to the wall.

[0016] In this invention, a battery 6 is installed on one side of the upper end of the circular plate, and a wire 7 is provided on one side of the battery 6. One end of the wire 7 is connected to the battery 6, and the other end is connected to the circuit board 8. Two support columns are provided at equal intervals at the lower end of the circuit board 8. The wire 7 between the circuit board 8 and the battery 6 facilitates the normal operation of the smoke detection function after power failure. A light-emitting diode 10 is installed on the upper end of the circuit board 8 and is fixed to the circuit board 8. An ionization chamber 16 is installed on one side of the upper end of the circuit board 8. The light-emitting diode 10 on one side of the circuit board 8 can light up to indicate the presence of smoke. Multiple smoke inlets are provided at equal intervals on both the upper and lower sides of the ionization chamber 16. A micro motor 9 is installed in the middle of the upper end of the ionization chamber 16. The drive shaft of the micro motor 9 passes through the upper end of the ionization chamber 16, and a blade 13 is sleeved on the outside of the drive shaft of the micro motor 9. The micro motor 9 and the blade 13 improve the sensitivity of the smoke detection.

[0017] In this invention, a metal disk 14 is installed inside the ionization chamber 16, and a smoke detector radiation source is installed in the middle of the metal disk 14. One side of the metal disk 14 is fixed to one side of the microchip 15 by a metal strip. The microchip 15 and the metal disk 14 are interconnected to facilitate the signaling after smoke is detected. A piezoelectric alarm 11 is installed in the middle of the circuit board 8. L-shaped fixing blocks are provided on both sides of the piezoelectric alarm 11. The L-shaped fixing blocks are snapped onto both sides of the circuit board 8. The piezoelectric alarm 11 on one side of the circuit board 8 facilitates the alarm prompting after smoke is detected.

[0018] Working Principle: When using the camera with smoke warning function of this utility model, the installation and fixing operation must first be completed. First, carefully align the base plate 4 with the preset installation position on the wall and attach it to the wall surface, ensuring that the fixing hole in the middle of the base plate 4 is precisely aligned with the drill hole on the wall. Next, insert the expansion bolt 5 from the inside of the fixing hole, so that one end is deeply embedded in the drill hole in the wall. Through the expansion action of the expansion bolt 5 in the drill hole, a preliminary fixing force is formed on the base plate 4. Then, take the fixing nut 12 and tighten it on the end of the expansion bolt 5 that is exposed on the outside of the base plate 4. Through the tight engagement of the fixing nut 12 and the expansion bolt 5, the base plate 4 is firmly pressed and fixed to the wall. At this time, there is no loose gap between the base plate 4 and the wall, ensuring the stability of the installation. After fixing the base plate 4, pick up the camera sleeve 2 and align its threaded end with the base plate 4. Slowly rotate the camera sleeve 2, using the threads on the inner wall of the camera sleeve 2 to engage with the threads on the outer side of the base plate 4 until the camera sleeve 2 and the base plate 4 are tightly connected without any shaking. This completes the overall installation and fixing of the camera. During this process, the camera housing 1 is firmly connected to one end of the camera sleeve 2 through a snap-fit ​​structure, forming a closed space that provides good protection for the internal camera mechanism and prevents direct damage to the camera mechanism from the external environment. At the same time, the multiple ventilation openings 3 equidistantly opened on the outer side of the camera sleeve 2 not only allow air circulation between the inside and outside of the device, but also the multiple vertical baffles set in the ventilation openings 3 can effectively block dust, small insects, fallen leaves and other foreign objects from entering the inside of the device, preventing foreign objects from contacting internal components and causing damage to the equipment, and ensuring the normal operation environment of the equipment. After installation, the power is turned on, and the camera enters normal working condition. The camera mechanism starts according to the preset program inside the camera sleeve 2, and begins to perform shooting, recording and other camera functions to monitor the surrounding environment in real time. At the same time, the smoke sensing components also enter working condition. The battery 6 is in standby mode and establishes a stable electrical connection with the circuit board 8 through the wire 7, providing power support to the circuit board 8 and related components at any time to ensure that the smoke sensing system can operate normally under various conditions. The circuit board 8 is kept horizontal and stable under the support of two equally spaced support columns at its lower end, maintaining an appropriate distance from surrounding components to avoid mutual interference. The micro motor 9 installed at the upper end of the circuit board 8 starts after the power is turned on, and its drive shaft begins to rotate, driving the blades 13 sleeved on the outside of the drive shaft to rotate at high speed. The rotation of the blades 13 generates airflow, which accelerates the air exchange and circulation inside and outside the camera sleeve 2, allowing the smoke in the surrounding environment to enter the ionization chamber 16 more quickly and fully through the multiple smoke inlets equally spaced on the upper and lower sides of the ionization chamber 16, thereby significantly improving the sensitivity of the smoke sensing and shortening the response time of the smoke detection. When smoke is generated and enters the ionization chamber 16, the smoke detector radiation source in the center of the metal disk 14 installed inside the ionization chamber 16 interacts with the smoke, changing the ionization state inside the ionization chamber 16. The metal disk 14 can sense this change in ionization state and accurately transmit this smoke signal to the microchip 15 through a metal strip connected to one side. As the core control component of the smoke sensing system, the microchip 15 immediately processes and analyzes the signal after receiving the smoke signal and quickly issues corresponding control commands. On one hand, the control commands are transmitted through the circuit on the circuit board 8 to the light-emitting diode 10 installed at the top of the circuit board 8, causing the light-emitting diode 10 to conduct and emit a bright light. The circuit board 8 provides a visual alert to those nearby that smoke is present, and it remains clearly visible even in low-light conditions. Simultaneously, control commands are transmitted to the piezoelectric alarm 11 located in the center of the circuit board 8. Upon receiving the command, the piezoelectric ceramic plate inside the alarm 11 vibrates, emitting a sharp, loud alarm sound. This provides a strong auditory warning, promptly alerting those nearby to the smoke situation. Furthermore, the L-shaped fixing blocks on both sides of the piezoelectric alarm 11 are securely fastened to both sides of the circuit board 8 via a snap-fit ​​structure, ensuring that the alarm 11 will not shift or fall off due to vibration during operation, thus guaranteeing the stable and continuous functioning of the alarm. In the event of a sudden power outage and interruption of external power supply, battery 6 immediately supplies power to circuit board 8 through wire 7, seamlessly connecting the power supply and ensuring the normal operation of the smoke sensing function is not affected by the power outage. The entire process of smoke entering ionization chamber 16 through smoke inlet, smoke detector radiation source sensing smoke, metal disk 14 transmitting signals, microchip 15 processing signals and issuing instructions, LED 10 illuminating and indicating, and piezoelectric alarm 11 sounding alarm can still proceed smoothly according to the normal procedure until battery 6 is exhausted or the fault is cleared and external power supply is restored. Thus, effective monitoring and alarm of smoke can be achieved even in emergency situations such as power outages.

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.
