Description

Technical Field

[0001] This invention relates to the field of fire protection facilities, specifically to a fire extinguisher box with real-time weight detection and alarm function. Background Technology

[0002] Fires have occurred frequently in recent years, and the frequent malfunctions of fire-fighting facilities pose a significant threat to people's lives and property. Fire extinguishers, in particular, are often undetectable due to their storage in fire extinguisher boxes. These boxes lack real-time monitoring of the extinguisher's status, making it difficult to detect problems such as insufficient pressure or expired extinguisher agents. More importantly, existing fire extinguisher boxes lack real-time weight monitoring capabilities, failing to detect abnormal weight changes caused by agent leaks or misuse. This prevents timely replenishment or replacement, further increasing the risk of unusable extinguishers during a fire, leading to irreversible consequences. Therefore, a fire extinguisher box product capable of automatically issuing alarms to alert personnel needs to be designed to address these issues. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a fire extinguisher box with real-time weight detection alarm function.

[0004] To solve the above-mentioned technical problems, the technical solution provided by the present invention is a fire extinguisher box with real-time weight detection alarm function: including a box base and a fire extinguisher box body that cooperates with the box base.

[0005] The base of the enclosure has a built-in weight detection unit, and a digital display screen for real-time weight display is embedded on the front side of the enclosure. The weight detection unit is electrically connected to the digital display screen.

[0006] The base of the box includes a base body and a support frame located at the lower part of the base body. The upper end of the support frame is provided with mounting holes that are fixedly engaged with the fire extinguisher box body.

[0007] The enclosure is equipped with an audible and visual alarm, which is electrically connected to the weight detection unit.

[0008] As an improvement, the fire extinguisher box is equipped with dual power supplies, and the main body of the fire extinguisher box has a power cord port and a battery compartment on the side.

[0009] As an improvement, the weight detection unit includes a weighing sensor, an A / D converter, and a microcontroller.

[0010] As an improvement, the weighing sensor is a strain gauge type, employing a metal foil strain gauge made of constantan alloy. The deformation of the strain gauge, adhered to an elastic body, generates a change in resistance, converting the weight signal into an electrical signal, ensuring accurate capture of minute weight changes. The A / D converter uses an RS485 wired interface and supports Modbus protocol and BLE5.0 wireless Bluetooth module. The microcontroller uses an STM32L051 low-power microcontroller to calculate real-time weight values ​​and integrates an intelligent range calibration algorithm to achieve adaptive range adjustment and data logic judgment.

[0011] As an improvement, the audible and visual alarm includes a loud horn and a high-brightness LED alarm light.

[0012] As an improvement, the loudspeaker uses a piezoelectric active buzzer with an externally nested ABS material resonance cavity. The high-brightness LED alarm light uses three surface-mount red LEDs, each with a brightness ≥5000mcd, connected in parallel; the high-brightness LED alarm light integrates an LED driver chip and uses a fixed-frequency strobe mode.

[0013] The advantages of this invention compared to the prior art are as follows: This invention is equipped with a weight detection unit, a digital display screen, and an audible and visual alarm. When these components are used together, an alarm can be issued in real time when the fire extinguisher experiences a gas leak that causes a decrease in weight, reminding staff to replace the fire extinguisher as soon as possible, thereby improving the reliability of the fire extinguisher.

Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of the indicated features.

[0028] The following is a detailed description of a fire extinguisher box with real-time weight detection and alarm function according to the present invention, with reference to the accompanying drawings.

[0029] like Figure 1 As shown, a fire extinguisher box with real-time weight detection alarm function includes a box base 100 and a fire extinguisher box body 200 that cooperates with the box base 100.

[0030] The base 100 includes a base body 130, a support frame 140 located at the bottom of the base body 130, and a digital display screen 120 located at the front of the base body 130. The base body 130 contains a fixedly connected weight detection unit 110. The digital display screen 120 is electrically connected to the weight detection unit 110 to display the weight of the fire extinguisher in real time. The support frame 140 has mounting holes 141 at its upper end that are fixedly fitted to the fire extinguisher box 200 for easy installation and use by the user.

[0031] The fire extinguisher box 200 has an audible and visual alarm 210 on the front and a power outlet 220 on the side. The audible and visual alarm 210 includes a loudspeaker 211 and a high-brightness LED alarm light 212. The loudspeaker 211 uses a piezoelectric active buzzer, supporting both continuous and intermittent sound modes, which can be switched via a control signal. It has an externally nested ABS material resonant cavity, and its internal spiral sound wave reflection structure directs and focuses sound waves onto the front of the box, reducing noise interference to non-target areas and avoiding sound attenuation caused by the enclosed interior space. The high-brightness LED alarm light 212 uses three parallel-connected surface-mount red LEDs, each with a brightness ≥5000mcd. These LEDs are focused by a focusing lens to form a 5mm diameter bright spot. The high-brightness LED alarm light integrates an LED driver chip and uses a fixed-frequency strobe mode, which is more visually noticeable than a constant-on mode and reduces power consumption by 40%.

[0032] like Figure 2 As shown, the base 100 includes a base body 130, a support frame 140 located at the bottom of the base body 130, and a digital display screen 120 located at the front of the base body 130. A weight detection unit 110 is fixedly connected inside the base body 130. The weight detection unit 110 includes a weighing sensor 111, an A / D converter 112, and a microcontroller 113. The digital display screen 120 is electrically connected to the weight detection unit 110, displaying the weight of the fire extinguisher in real time. The upper end of the support frame 140 has mounting holes 141 that are fixedly fitted to the fire extinguisher box body 200. The weighing sensor 111 is a strain gauge type weighing sensor, using a metal foil strain gauge made of constantan alloy. The strain gauge, bonded to an elastic body, deforms to generate a change in resistance, converting the weight signal into an electrical signal, ensuring accurate capture of minute weight changes. The A / D converter 112 uses an RS485 wired interface and supports the Modbus protocol and BLE 5.0 wireless Bluetooth module. The microcontroller controller 113 uses an STM32L051 low-power microcontroller to calculate the real-time weight value and integrates an intelligent range calibration algorithm to realize adaptive range adjustment and data logic judgment.

[0033] like Figure 3 As shown, the weighing sensor obtains the weight of the fire extinguisher in real time. The analog signal obtained by the weight sensor is converted into a digital signal by the A / D converter and transmitted to the microcontroller. When the weight of the fire extinguisher is lower than the set threshold, the microcontroller controls the loudspeaker and the bright LED alarm to sound an alarm to remind the staff.

[0034] like Figure 4 As shown, there is a base 100 and a fire extinguisher box body 200 that cooperates with the base 100.

[0035] The base 100 includes a base body 130, a support frame 140 located at the bottom of the base body 130, and a digital display screen 120 located at the front of the base body 130. The base body 130 contains a fixedly connected weight detection unit 110. The digital display screen 120 is electrically connected to the weight detection unit 110 to display the weight of the fire extinguisher in real time. The support frame 140 has mounting holes 141 at its upper end that are fixedly fitted to the fire extinguisher box 200 for easy installation and use by the user.

[0036] The fire extinguisher box is equipped with a power cord port 220 on the side and a battery compartment 230 to adapt to different usage scenarios.

[0037] In practical implementation, the fire extinguisher box 200 is opened, and the weight detection unit 110 is connected to the digital display screen 120. The weight detection unit 110 is also connected to the audible and visual alarm 210. The fire extinguisher is placed on the base body 130. The weight detection unit 110 monitors the weight of the fire extinguisher in real time and transmits the data to the digital display screen 120, which accurately displays the real-time weight of the fire extinguisher. When the fire extinguisher loses weight due to gas leakage and reaches the pre-set alarm weight, the audible and visual alarm 210, located outside the fire extinguisher box 200, is activated to alert personnel and prompt them to repair or replace the fire extinguisher as soon as possible, thus avoiding potential safety hazards.

[0038] Although some embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations of these embodiments without departing from the principles and spirit of the present invention are within the scope of protection of the claims of the present invention.
