Heater capable of being conveniently fixed on outer side surfaces of respirators with different sizes

Abstract

The invention discloses a heater capable of being conveniently fixed to the outer side surfaces of respirators of different sizes. The heater comprises a heating shell, first secondary hook-and-loop fasteners, first connecting cloth and second connecting cloth; a heat preservation shell is arranged on the outer side surface of the heating shell; a waterproof shell is arranged on the outer side surface of the heat preservation shell; a top sealing sleeve is arranged on the upper side surface of the heating shell; a hollow sleeve is arranged on the upper side surface of the top sealing sleeve; an adjusting rope penetrates through the interior of the hollow sleeve; a fastening device is arranged on the adjusting rope; and the first secondary hook-and-loop fasteners are arranged on the front side surface of the waterproof shell. According to the heater capable of being conveniently fixed to the outer side surfaces of respirators of different sizes, a plurality of secondary clamping bucklesand the first secondary hook-and-loop fasteners are adopted; when the heater needs to be installed on the outer side surface of a respirator; primary clamping buckles are connected with the secondaryclamping buckles at proper positions according to the diameter of the respirator, meanwhile, first primary hook-and-loop fasteners are connected with the first secondary hook-and-loop fasteners at proper positions; and therefore the heater can be conveniently fixed to the outer side surfaces of respirator bottles of different sizes.

Description

technical field [0001] The invention specifically relates to the technical field of respirators, in particular to a heater that is conveniently fixed on the outer surfaces of respirators of different sizes. Background technique [0002] The respirator is a self-contained open-air respirator, also known as a gas storage mask, sometimes called a fire mask. It has the advantages of light weight, small size, convenient use and maintenance, comfortable wearing, and stable performance. The product is equipped with It is a full-face mask with wide field of vision, bright and good airtightness. At the same time, the pressure reducing valve device is equipped with a residual gas alarm, which can send an audible signal to the wearer within the specified pressure range of the gas cylinder to remind the user to evacuate the scene in time. Ideal personal respiratory protective device for disaster relief and fire fighting operations. [0003] When the heater is installed on the outer sid...
