Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, specifically a dynamically adjustable smoking monitoring device. Background Technology

[0002] Smoking in public places is not only harmful to the health of the smoker, but also poses a serious health threat to the surrounding people. In particular, the harm of secondhand smoke has become a major issue in the field of global public health. Therefore, smoking monitoring devices are usually installed in some public places to determine whether someone is smoking.

[0003] Smoking monitoring devices are intelligent devices or systems that use advanced technology to monitor, identify, and issue early warnings for smoking behavior in a specific area in real time. They are widely used in smoke-free places such as hospitals, schools, factories, office buildings, and public transportation to maintain public environmental safety and health.

[0004] However, most existing smoke monitoring devices have various problems. For example, in a smoke monitoring device disclosed in publication number CN206921273U, although it can detect the amount of cigarette smoke near the device and issue light and voice alarms, which can effectively reduce people's inhalation of secondhand smoke and the occurrence of fires, this technical solution and most current smoke monitoring devices can only passively capture and monitor smoke floating in the air, and cannot actively capture it, which has certain limitations.

[0005] To address this, a dynamically adjustable smoking monitoring device is proposed. Utility Model Content

[0006] This utility model addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the purpose of this utility model is to overcome the aforementioned shortcomings in existing technologies by proposing a dynamically adjustable smoking monitoring device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A dynamically adjustable smoking monitoring device includes a rectangular outer shell, a protective shell, and a control base. The protective shell, which has a trapezoidal structure, is connected to the bottom of the rectangular outer shell. The protective shell has through holes around its perimeter. The control base is fixed at the center of the bottom of the protective shell. A smoking monitoring mechanism is provided on the control base. A flow guiding mechanism is provided inside the rectangular outer shell.

[0009] The smoking monitoring mechanism includes a smoking detection sensor, which is mounted on a control base and located in the internal cavity of the protective shell. The flow guiding mechanism includes a linkage rod and a linkage roller. The linkage rod is horizontally and rotatably connected to the center of the internal cavity of the rectangular shell. The linkage roller is fixed on the linkage rod, and the linkage rod is located at the center of the linkage roller. The threshold of the smoking detection sensor can be dynamically adjusted according to the concentration of particulate matter in the environment. It can also receive adjustment commands and broadcast commands from a remote management platform via an Internet of Things (IoT) gateway.

[0010] Preferably, the smoking monitoring mechanism further includes an indicator light and a speaker. The indicator light is fixed at the bottom center of the control base, and the speaker is embedded in the control base and arranged around the indicator light.

[0011] Preferably, the air guiding mechanism further includes a servo motor and an air outlet. The servo motor is fixed on the side wall of the rectangular housing, and the output shaft of the servo motor is connected to one end of the linkage rod. The air outlet is located at the top center of the rectangular housing.

[0012] Preferably, the linkage roller is provided with a plurality of fan blades at equal intervals around its periphery, and the plurality of fan blades together form a cylindrical structure.

[0013] Preferably, heat sinks are provided on the sidewalls of the rectangular shell, and the heat sinks are symmetrically arranged on the rectangular shell.

[0014] Preferably, a fixing plate is fixed to the top of the rectangular shell. The fixing plate has an L-shaped structure, and four fixing plates are arranged symmetrically in the front, back, left, and right directions.

[0015] The beneficial effects of this utility model are:

[0016] This device uses a smoke detection sensor to monitor the concentration of particulate matter in the environment in real time. It determines whether someone is smoking by setting a concentration threshold. If the threshold is exceeded, it will play a voice prompt such as "No Smoking". During detection, a servo motor drives the linkage rod and linkage roller to rotate, which in turn drives the airflow inside the rectangular shell. Air enters the internal cavity of the rectangular shell from the protective shell and flows out through the air outlet. This allows the device to actively detect smoke and dust in the air, solving the problem that the transmission device can only detect passively. It also makes the device more sensitive and efficient. In addition, the airflow process also dissipates heat from the entire device, preventing the device from overheating and damaging electronic components. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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. Example

[0024] like Figures 1 to 4 As shown, a dynamically adjustable smoking monitoring device includes a rectangular shell 1, a protective shell 2, and a control base 3. The trapezoidal protective shell 2 is connected to the bottom of the rectangular shell 1, and the protective shell 2 is provided with through holes around its perimeter. The control base 3 is fixedly installed at the bottom center of the protective shell 2, and a smoking monitoring mechanism is provided on the control base 3. A flow guiding mechanism is provided inside the rectangular shell 1.

[0025] The smoking monitoring mechanism includes a smoking detection sensor 6, which is mounted on the control base 3 and located in the internal cavity of the protective shell 2. The flow guiding mechanism includes a linkage rod 9 and a linkage roller 10. The linkage rod 9 is horizontally and rotatably connected to the center of the internal cavity of the rectangular shell 1. The linkage roller 10 is fixed on the linkage rod 9, and the linkage rod 9 is located at the center of the linkage roller 10. The threshold of the smoking detection sensor 6 can be dynamically adjusted according to the concentration of particulate matter in the environment. It can also receive adjustment instructions and broadcast instructions from the remote management platform through the Internet of Things.

[0026] The smoking detection mechanism also includes an indicator light 4 and a speaker 5. The indicator light 4 is fixed at the bottom center of the control base 3, and the speaker 5 is embedded in the control base 3 and arranged around the indicator light 4.

[0027] The air guiding mechanism also includes a servo motor 8 and an air outlet 11. The servo motor 8 is fixed on the side wall of the rectangular housing 1, and its output shaft is connected to one end of the linkage rod 9. The air outlet 11 is located at the top center of the rectangular housing 1.

[0028] The linkage roller 10 has several fan blades equidistantly arranged around its periphery, and the multiple fan blades together form a cylindrical structure.

[0029] In this device, the smoke detection sensor 6 detects the concentration of particulate matter in the environment in real time. It determines whether someone is smoking by setting a concentration threshold. When the threshold is exceeded, a voice prompt such as "No Smoking" is broadcast. During detection, the servo motor 8 drives the linkage rod 9 and the linkage roller 10 to rotate as a whole, which in turn drives the airflow inside the rectangular shell 1. Air enters the internal cavity of the rectangular shell 1 from the protective shell 2 and flows out through the air outlet duct 11. This allows the device to actively detect smoke and dust in the air, solving the problem that the transmission device can only detect passively. It also makes the device more sensitive and efficient. In addition, the airflow process also dissipates heat from the entire device, preventing the device from overheating and damaging electronic components. Example

[0030] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0031] Heat sinks 7 are provided on the side wall of the rectangular shell 1. The heat sinks 7 are made of aluminum alloy composite material to form a rectangular structure and are symmetrically arranged on the rectangular shell 1 to increase the heat dissipation area and enable the device to dissipate heat quickly.

[0032] A fixing plate 12 is fixed to the top of the rectangular outer shell 1. The fixing plate 12 has an L-shaped structure and four are arranged symmetrically in the front, back, left and right, so that the device can be quickly connected and fixed to the external structure through the fixing plate 12. Example

[0033] like Figure 5 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0034] The smoking detection sensor 6 is connected to the cloud platform via an IoT gateway. It has three threshold levels, adjustable via buttons on the hardware. Under normal conditions, the indicator light is green. For each level exceeding the threshold, the sensor will trigger an audible and visual alarm, turning the light red and activating the built-in voice broadcast module. The built-in voice file can be changed as needed, and a volume control knob allows adjustment of the voice volume. The threshold values ​​of the smoking detection sensor 6 can be dynamically adjusted based on the ambient particulate matter concentration. The device can also receive adjustment commands and broadcast commands from a remote management platform via the IoT gateway.

[0035] This device has a dynamic adjustment function:

[0036] The device reports a data message every 10 seconds. The device can accept dynamic adjustment commands issued by the remote platform, including gear commands and broadcast commands.

[0037] The backend receives data packets from the device every 10 seconds. When the difference between the maximum and minimum values ​​in the most recent 20 data packets is greater than the threshold set by the backend, the backend will send a command to the device to control the voice playback.

[0038] This feature can address the issue of varying PM levels in different environments.

[0039] Working principle: When using this smoking detection device, the smoking detection sensor 6 first detects the concentration of particulate matter in the environment in real time. It determines whether someone is smoking by setting a concentration threshold. When the concentration exceeds the threshold, it will play a voice prompt such as "No Smoking". The device reports a data message every 10 seconds. The hardware itself has a threshold setting. Under normal conditions, the light is green. When the concentration exceeds a certain level, the sensor will sound an alarm, the light will turn red, and the speaker 5 will play a voice prompt. The device can also receive dynamic adjustment commands from a remote platform, including threshold commands and broadcast commands. The backend receives the data message from the device every 10 seconds. When the difference between the maximum and minimum values ​​in the most recent data is greater than the threshold set by the backend, the backend will send a command to control the voice playback. During detection, the servo motor 8 drives the linkage rod 9 and the linkage roller 10 to rotate as a whole, which in turn drives the airflow inside the rectangular shell 1. The air enters the internal cavity of the rectangular shell 1 from the protective shell 2 and flows out through the air outlet duct 11.
