Description

Technical Field

[0001] This utility model relates to the field of isolation oxygen generator technology, specifically to an isolation oxygen generator ignition device. Background Technology

[0002] In civil defense projects, ensuring the safety of personnel inside is crucial in responding to potential threats of war, natural disasters, or other emergencies. Oxygen supply is one of the fundamental requirements for sustaining life activities. In isolation mode, when external air is unsafe due to pollution, toxic gases, or other reasons, civil defense projects rely on internal equipment to provide oxygen.

[0003] One traditional method of oxygen supply is the use of oxygen candles. An oxygen candle is a device that produces oxygen through a chemical reaction, releasing a large amount of oxygen in a short time to provide the necessary oxygen supply to a confined space. In civil defense projects, oxygen candles are typically energized via positive and negative electrode clamps to trigger the internal chemical reaction. This energizing method uses a direct-insertion design, where the clamps are directly inserted into the electrodes of the oxygen candle, igniting it through the action of the current and initiating the oxygen release process. This method is relatively cumbersome to install.

[0004] However, the traditional direct-plug electrical clamp method has some drawbacks. First, the direct-plug design can lead to poor contact between the clamp and the oxygen candle electrode, affecting current transmission and the ignition effect of the oxygen candle. Second, the direct-plug design can loosen or become damaged during long-term use, resulting in unstable or interrupted oxygen supply. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an isolation oxygen generator ignition device, which solves the problems of cumbersome installation process and poor contact between the wire clamp and the oxygen candle electrode in traditional oxygen candle ignition methods, which affect the current transmission and the ignition effect of the oxygen candle, and may loosen or be damaged during long-term use, leading to unstable or interrupted oxygen supply.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An oxygen generator ignition isolation device includes an outer cylinder unit and an oxygen candle mounting unit, wherein the oxygen candle mounting unit is disposed on the outer cylinder unit, and the outer cylinder unit includes:

[0007] Stainless steel outer cylinder;

[0008] An insulating heat insulation board is installed at the bottom of the stainless steel outer cylinder;

[0009] A positive power supply block is mounted on an insulating heat-insulating plate and is connected to a positive power supply line.

[0010] A spring, which is sleeved on the outside of the positive terminal block of the power supply;

[0011] The oxygen candle mounting unit includes:

[0012] Ignition positive electrode, which is positioned directly above the power supply positive electrode block;

[0013] The oxygen candle body is positioned above the ignition positive electrode.

[0014] Preferably, the oxygen candle mounting unit further includes:

[0015] A stainless steel outer shell, which is slidably connected to a stainless steel outer cylinder;

[0016] A cover, which is movably mounted on top of the stainless steel housing;

[0017] The upright is fixedly connected inside the stainless steel casing.

[0018] Preferably, the oxygen candle body is movably sleeved on the upright.

[0019] Preferably, the ignition positive electrode is fixedly connected to the bottom center of the stainless steel shell, and the ignition positive electrode is connected to the oxygen candle body.

[0020] Preferably, the ignition positive electrode and the power supply positive electrode block are mutually offset.

[0021] Preferably, the ignition positive electrode abuts against the spring.

[0022] Preferably, the top of the cap has an oxygen vent, and the bottom of the cap is fixedly connected to a support plate.

[0023] Preferably, connecting blocks are fixedly connected to both sides of the support plate, and fastening bolts are threaded onto the connecting blocks.

[0024] This utility model discloses an ignition isolation device for an oxygen generator, which has the following beneficial effects:

[0025] This isolated oxygen generator ignition device features a stainless steel outer cylinder with an inner diameter 1mm larger than the outer shell. An insulating heat-resistant plate is installed at the bottom of the outer cylinder, with a spring and a positive power supply block positioned in the center. The positive power supply block is connected to the positive power supply line. The stainless steel outer cylinder carries a negative power supply. The oxygen candle body is inserted directly into the stainless steel outer shell through its upper opening. The positive ignition electrode of the oxygen candle body is located at the center of the bottom of the stainless steel outer shell. Moving the stainless steel outer shell downwards aligns the positive ignition electrode with the positive power supply block. The stainless steel outer shell is connected to the outer cylinder with negative polarity. When oxygen release is detected, the positive power supply block is energized, and the oxygen candle body releases oxygen. This simplifies the installation process and solves the inconvenience of the previous method where the oxygen candle required clamps to hold its positive and negative electrodes in place before discharging oxygen. It also avoids the potential for poor contact between the clamps and the oxygen candle electrodes, and the possibility of loosening or damage during long-term use, which can occur with a direct-insertion design.
