[0037] The trace dust detection device currently publicly disclosed in the society is based on a laser assembly or a special sampling device to accurately sample and measure the dust in the working site environment. Such public health environment dust detection equipment is large in size, heavy in quality, cannot be worn, and cannot detect trace dust in the mask. For the mining, construction, ceramic and other industries, dust penetration of dustproof masks seriously threatens occupational health and safety. In view of the shortcomings of the public health environment dust detection equipment, such as large size, heavy quality, cannot be worn, and cannot detect trace dust in the mask, the present application discloses a portable, wearable trace dust early warning device based on a dustproof mask filter film.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1 As shown, this is a micro-dust early warning device based on a dust mask filter membrane according to an embodiment of this application, which mainly includes a dust filter membrane device 100 and a dust monitoring device 200.

[0041] The dust filter membrane device 100 is used to sense dust passing through the filter membrane of the dust mask and generate a dust sensing signal. The dust monitoring device 200 is used to receive the dust sensing signal and perform dust data analysis and generate dust exceeding the standard alarm signal based on the dust sensing signal.

[0042] The following, in conjunction with this embodiment, will specifically describe the structural composition and functional implementation of the above two components.

[0043] In this embodiment, the dust filter membrane device is placed in the inner layer of the mask and mainly includes a chip plate 1, a chip mesh 2, and a microporous plate 3.

[0044] Chip board 1 uses an array of silver wires inside and is 3D printed with insulating gel to transmit dust sensing signals.

[0045] Chip mesh 2 covers the chip board 1 and is connected to the internal circuit of chip board 1 by silver wire array. It is used to sense dust and generate dust sensing signal. The dust sensing signal is transmitted in the form of current.

[0046] The microplate 3 covers the chip mesh 2 and uses a hydrophobic insulating NCF film to form holes for dust to pass through. Each hole covers up to four electrode lines.

[0047] The chip in this embodiment can be made very small, about the size of a thumbnail. The dust collection process is entirely driven by external force. The dust is propelled through the meltblown filter layer of the mask by the breathing airflow, then passes through the microporous plate 3 and is paralleled with the chip mesh 2, generating a microcurrent as a dust sensing signal, thereby collecting the dust signal. The dust filter membrane device 100 is reusable and can be collected, cleaned, and reused by technicians.

[0048] In this embodiment, the signal transmission between the dust filter membrane device 100 and the dust monitoring device 200 adopts a 32-channel silver paste FPC flexible flat cable 4, and a corresponding adapter is provided.

[0051] Specifically, the counting processor 5 mainly comprises a counting unit, a threshold unit, a storage unit and an alarm signal unit.

[0052] The counting unit is used to receive the dust sensing signal, generate dust data through data accumulation and store the dust data in the storage unit in real time. The threshold unit is used to preset the alarm threshold, and the specific threshold value can also be stored in the storage unit. The alarm signal unit is used to generate a dust over-standard alarm signal according to the dust data and the alarm threshold when the dust data is greater than the alarm threshold.

[0053] Further, the dust over-standard alarm signal can be divided into multiple different levels, and the specific adjustment can be made according to actual needs.

[0054] In the embodiment, an adjustment button 9 is also provided for adjusting the alarm threshold, and a light-emitting diode 7 is used for signal feedback during debugging. The adjustment button 9 can also be used to restore the factory settings.

[0055] In the embodiment, the display panel 6 is used to display the dust data and the dust over-standard alarm signal.

[0056] The alarm device is used to issue an over-standard alarm according to the dust over-standard alarm signal and mainly comprises an optoelectronic alarm device and a sound alarm device.

[0057] The optoelectronic alarm device is used to issue an over-standard alarm in the form of optoelectronics according to the dust over-standard alarm signal, and the light-emitting diode 7 can be used.

[0058] The sound alarm device is used to issue an over-standard alarm in the form of sound according to the dust over-standard alarm signal, and the buzzer 8 can be used.

[0059] In the embodiment, the entire dust early warning device relies on a button cell 11 for power supply and is fixed on the dust monitoring device through a button card 10.

[0060] The micro dust early warning device based on the dust mask filter film in the embodiment is designed based on the dust mask and is convenient to wear. The dust amount of the mask can be monitored in real time and an alarm can be issued in time, so that the professional safety and health protection are effectively improved.
