Embodiment 1

[0039] Embodiment 1: A starting device for a chemical oxygen self-rescuer, combined with figure 2 , including a protective cover 1, the lower end of the protective cover 1 is connected to an oxygen-evolving agent storage chamber 2, and an isolation film 3 is fixed between the protective cover 1 and the oxygen-emitting agent storage chamber 2. Inside the protective cover 1 , an elastic starting bag 4 is fixed on the upper end surface of the isolation membrane 3 , and a needle 43 is fixed inside the elastic starting bag 4 . The upper end of the protective cover 1 is hinged with the activation assembly 6 , and the activation assembly 6 abuts against the elastic activation bag 4 . Rotate the starting component 6, the starting component 6 pushes the elastic starting bag 4 to drive the puncture needle 43 to pierce the diaphragm, so as to realize the starting of the chemical oxygen self-rescuer.

Embodiment 2

[0052] Embodiment 2: A starting device for a chemical oxygen self-rescuer, combined with Image 6 , the difference between this embodiment and Embodiment 1 is that: the locking section 65 and the driving section 62 on the starting assembly 6 fix the projection 66, and the positioning block 14 is fixed at the position corresponding to the projection 66 on the protective cover 1, and the positioning block 14 The connection with the protective cover 1 has a certain degree of elasticity, which is convenient for the protrusion 66 to fit into the groove formed between the positioning block 14 and the protective cover 1 .

[0053] After the starting assembly 6 rotates 180 degrees around the hinge shaft 61 , the slot 651 engages with the positioning portion 52 , and at the same time, the projection 66 engages and fixes with the positioning block 14 , further strengthening the locking of the starting assembly 6 .

Abstract

The invention relates to a chemical oxygen self-rescuer starting device which comprises a protection cover and an oxygen releasing agent storing chamber which are arranged up and down. An isolation film is fixed between the protection cover and the oxygen releasing agent storing chamber, a starting assembly is hinged to be position above the protection cover, an elastic starting bag is arranged inthe protection cover in a manner of being fixed to the isolation film, and a felting needle is fixed to the end, far away from the isolation film, in the elastic starting bag; and the starting assembly comprises a driving section and a motion section, the distance between the end of the motion section and a hinge shaft of the starting assembly is larger than the distance between the felting needle and the isolation film. According to the chemical oxygen self-rescuer starting device, the starting manner of pulling the starting assembly open in the axial direction is changed into a rotary pressing manner, and the starting assembly is conveniently started.

Description

technical field [0001] The invention relates to the field of lifesaving equipment used in coal mines, in particular to a starting device for a chemical oxygen self-rescuer. Background technique [0002] The self-rescuer is a portable respiratory protective device for personnel entering the well to prevent harmful gas poisoning or hypoxia suffocation when a fire occurs underground, gas, coal dust explosion, coal and gas outburst. [0003] The chemical oxygen self-rescuer uses chemical substances (such as potassium superoxide) to generate oxygen. Potassium superoxide reacts with water or carbon dioxide as follows: 4KO 2 +2H 2 O=4KOH+3O 2 ,4KO 2 +2CO 2 = 2K 2 CO 3 +3O 2 ; That is, when potassium superoxide contacts with water or carbon dioxide, oxygen will be produced, which can support the wearer to escape from the dangerous area. Therefore, potassium superoxide pills are usually placed inside the chemical oxygen self-rescuer, and the potassium superoxide pills are sea...
