Technical Field

[0001] This utility model specifically relates to the field of formaldehyde concentration monitoring technology, and more specifically to an intelligent formaldehyde concentration monitoring device. Background Technology

[0002] Formaldehyde is widely present in various building materials, furniture, and textiles in our daily lives. For example, formaldehyde-containing adhesives are used in the production of plywood, particleboard, and other boards, and newly renovated houses often release large amounts of formaldehyde; some newly purchased furniture, especially furniture made of engineered wood, will also continue to release formaldehyde.

[0003] As people's living standards improve and their health awareness increases, the requirements for indoor environmental quality are becoming increasingly stringent. Therefore, formaldehyde concentration monitoring devices are used to investigate the indoor gas environment. Because formaldehyde carried by indoor boards, furniture, etc., is continuously volatile, long-term gas monitoring is necessary. However, continuous and prolonged gas monitoring can cause the formaldehyde concentration monitoring device to become fatigued, easily reducing its lifespan and affecting the test data. Furthermore, existing formaldehyde concentration monitoring devices lack convenient installation methods. Adhesive methods may result in the device falling off due to insufficient adhesive strength, while magnetic fixing is limited by the materials used in the installation environment and cannot be used on surfaces such as wood and plastic, greatly restricting the flexibility and convenience of installation.

[0031] With reference to the accompanying drawings of the embodiments of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below.

[0032] Example: Please refer to the appendix Figure 1-4 This utility model provides a technical solution: an intelligent formaldehyde concentration monitoring device, comprising:

[0033] The detection chamber 5 is equipped with a formaldehyde concentration detection module for detecting formaldehyde concentration.

[0034] Signal chamber 6 is fixedly installed on the top of detection chamber 5. Signal chamber 6 is equipped with a wireless communication module and an ARM processing module. The ARM processing module receives the information collected by the formaldehyde concentration detection module in real time and connects to the control terminal through the wireless communication module.

[0035] Threaded connector 8 is fixed on the bottom surface of the detection chamber 5, and threaded connector 8 is threadedly connected to the fixed pile assembly 4.

[0036] The extension tube 3 has one end fixedly connected to the collection port of the detection chamber 5, and the other end of the extension tube 3 is fixedly connected to the collection seat 2, and the air inlet of the collection seat 2 is fixedly installed with the air nozzle 1.

[0037] And a miniature air pump, which is fixedly installed in the collection base 2, and the miniature air pump is connected between the extension tube 3 and the air nozzle 1.

[0038] In this embodiment, the signal compartment 6 is also equipped with a wake-up module and a PLC control module. The wake-up module is connected to the micro air pump and the formaldehyde concentration detection module. The control terminal can drive the wake-up module to wake up the micro air pump and the formaldehyde concentration detection module at regular intervals through the PLC control module.

[0039] In other words, the combination of a miniature air pump and a formaldehyde concentration detection module for multi-segment timed detection of indoor gases effectively reduces the workload of this new device and achieves the following effects: Firstly, the release rate of formaldehyde varies at different times of day, and multi-segment timed detection can simulate changes in the indoor environment during daily life. During the day, people are active, and behaviors such as opening windows for ventilation will change the indoor formaldehyde concentration; at night, doors and windows are closed, indoor air is relatively stagnant, and the formaldehyde concentration may gradually increase. By detecting at different times, the device can better reflect the dynamic changes in indoor formaldehyde concentration over time during actual living, allowing users to clearly understand when the peak and trough values ​​of formaldehyde concentration occur within a day, thus enabling them to take more targeted prevention and control measures.

[0040] On the other hand, in the long run, formaldehyde release is a gradual process, but it can fluctuate due to various factors. By conducting long-term, multi-segment, timed monitoring and collecting a large amount of formaldehyde concentration data, a more accurate curve of formaldehyde concentration changing over time can be plotted. This helps analyze the long-term trend of formaldehyde release, predict when indoor formaldehyde concentration will decrease to a safe level, and provide a scientific basis for when it is suitable to move into a newly renovated house.

[0041] In this embodiment, the PLC control module, wake-up module, micro air pump, formaldehyde concentration detection module, wireless communication module, and ARM processing module are all powered by a battery module located in the signal compartment 6.
