Embodiment 2

[0066] In the second embodiment, the wearing method of the mine dust filter air supply type dust mask, using the mine dust filter air supply type dust mask in embodiment 1, comprises the steps:

[0067] Step A1, put the breathing mask 103 on the nose and mouth of the user, and make the inside edge of the breathing mask 103 fit the face. After wearing the breathing mask 103, wear the head strap 104 on the user's head and neck, so that The breathing mask 103 is comfortably fixed on the face;

[0068] Step A2, wake up and turn on the micro fan 12;

[0069] Step A3, put the assembly from the back of the neck and make it wrap around the neck, hold the outer cone sleeve joint 31 on one side of the breathing mask 103 with one hand, and hold the quick swivel joint 158 ​​of the host machine 101 with the other hand, and place the outer cone Push the sleeve joint 31 into the quick swivel joint 158 ​​and then rotate the outer ring 1581 to connect the host 101 with the breathing mask 103;...

Embodiment 3

[0074] In the third embodiment, the test method of the mine dust filter air supply type dust mask uses the mine dust filter air supply type dust mask in embodiment 1, comprising the steps:

[0075] Step B1, put the mine-used dust filter dust mask on the user's head, press the power button 411 to start the host 101;

[0076] Step B2. After the wearer breathes normally, the system starts to adjust the air supply volume according to the breathing volume;

[0077] Step B3, press and hold the test key 412 for three seconds to enter the test mode, the micro fan 12 starts and supplies air with the maximum air volume, then press the test key 412 to reduce the air volume by one level to supply air, and then press the test key 412 to decrease the air volume by one level Air supply, and then press the test button 412, the fan will supply air at the maximum air volume again, and so on;

[0078] Step B4, press the power button 411 in the test mode to exit the test mode.

Abstract

The invention belongs to mine personal protection type portable instruments and equipment, and relates to a mine dust filtration and air supply type dustproof mask. The mine dust filtration and air supply type dustproof mask comprises a breathing mask, a head tying belt, a main machine and a filter; the breathing mask covers mouth and the nose parts of a user, a breathing exchange space is formedbetween the breathing mask and the mouth and the nose parts of the user; the head tying belt is connected on the breathing mask, the head tying belt assists the breathing mask in covering the mouth and the nose parts of the user in the mode of being fixed to a head, a shoulder and a neck of the user; a main body of the main machine is of a tubular structure, a micro fan is arranged in the main machine; the filter is connected to one end part of the tubular structure of the main machine body, the main machine and the filter form an assembly body with a tubular main body; and the assembly body is connected with the breathing mask to enable that the breathing exchange space communicates with the interior of an assembly body main pipe, the assembly body is lapped on the shoulder and neck of auser, and outside air is driven by the micro fan to enter the main machine through the filter. The mine dust filtration and air supply type dustproof mask actively supplies air and is portable and efficient. The invention further provides a wearing method of the dustproof mask.

Description

technical field [0001] The invention belongs to a portable instrument and equipment for personal protection in mines. The invention belongs to a dust filter mask for mines, in particular to a dust filter air supply type dust mask for mines. Background technique [0002] The environment of coal mine operation is harsh, the dust is heavy, the ventilation conditions are poor, and the incidence of pneumoconiosis is high, which seriously endangers the health of workers. The underground workers of coal mines need to wear corresponding respiratory protective equipment to avoid the damage of high dust environment to health and reduce the risk of pneumoconiosis. reduce the probability of disease and improve the efficiency of coal mine underground work. However, in the existing breathing dust masks for mines, the dust particles of the self-priming filter dust masks are gradually deposited on the filter layer after long-term use, resulting in continuous increase of breathing resistance...
