Description

Technical Field

[0001] The utility model relates to the technical field of gas masks, in particular to a gas mask with a manual water mist brush. Background Art

[0002] At present, when a gas mask is used, it is easy for water vapor produced by breathing to cause water mist to form inside the window, which affects the wearer's vision and reduces the wearer's work efficiency. Utility Model Content

[0003] In view of the above technical problems in the related art, the utility model proposes a gas mask with a manual water mist brush, which can solve the above problems.

[0004] In order to achieve the above technical purpose, the technical solution of the utility model is implemented as follows:

[0005] A gas mask with a manual water mist brush comprises a gas mask body, a gas mask window lens, an exhalation valve, and a talker are arranged on the front of the gas mask body, headband fixing buckles are arranged on both sides of the gas mask body, a water mist brush is arranged on the inner surface of the gas mask window lens, and a water mist brush external knob is arranged on the outer surface, and the water mist brush external knob is connected to the water mist brush through a manually rotating sealing component.

[0006] Furthermore, a window clamp is provided on the gas mask cover body, and the gas mask window lens is fixedly connected to the window clamp via a clamp locking screw nut.

[0007] Furthermore, the water mist brush includes an elastic bracket assembly and a water mist brush shrapnel assembly. The bottom end of the elastic bracket assembly is connected to the manual rotating sealing assembly. The water mist brush shrapnel assembly is arranged at the top end of the elastic bracket assembly. The water mist brush shrapnel assembly is provided with a leather felt.

[0008] Furthermore, the elastic support assembly includes a stainless steel elastic connecting plate and a 1 mm thick rigid pressure plate.

[0009] Furthermore, the manual rotating sealing assembly includes rubber sealing rings, sealing compression nuts, and sealing pads provided on both sides of the gas mask window lens, and a sliding bearing is provided between the rubber sealing rings on both sides.

[0010] Furthermore, the leather felt wraps two stainless steel support plates, which are connected by rotatable screws to form an arch shape, and fits tightly against the inner side of the lens.

[0011] The beneficial effects of the utility model are as follows: when the gas mask of the present application has fog and water droplets inside the lens blocking the vision, the user can, without taking off the gas mask, use the hand to turn the external knob to drive the elastic bracket assembly and the water mist brush shrapnel assembly to effectively remove the water mist within the range of the window lens wiped by the rotating water mist brush, thereby achieving a good field of vision.
