An oxygen filling mechanism 3 is provided at the top of the oxygen bomb head for filling the oxygen bomb tube with oxygen.

[0044] The oxygen filling mechanism 3 includes an oxygen filling valve seat 31, an oxygen filling nozzle 32, and an oxygen filling core 33;

[0045] The oxygen filling valve seat 31 is fixed at the central axis of the oxygen bomb head 11, the oxygen filling nozzle 32 is located at the top of the oxygen filling valve seat 31, and the oxygen filling element 33 is located between the oxygen filling nozzle 32 and the oxygen filling valve seat 31; the bottom of the oxygen filling valve seat 31 is provided with a number of oxygen filling channels 311, which are symmetrically arranged. One end of the oxygen filling channel 311 is connected to the oxygen filling element 33, and the other end is connected to the inside of the oxygen bomb cylinder 2.

[0046] The laser ignition mechanism 4 includes a laser base 41, a laser head 42, a glass column 43, and a laser outer cover 44;

[0047] The laser base 41 is fixed to the bottom of the oxygen filling valve seat 31, the laser cover 44 is fixed to the bottom of the laser base 41, the laser head 42 is located inside the laser base 41, and the laser head 42 is positioned between the bottom of the laser base 41 and the top of the laser cover 44; the glass column 43 is located inside the laser cover 44, and the glass column 43 is positioned between the bottom of the laser head 42 and the laser cover 44.

[0049] In this embodiment, a laser electrode 421 is provided on the laser head 42, and the laser electrode 421 is vertically arranged on one side of the top of the laser head 42.

[0050] In this embodiment, an oxygen bomb septum 41a is provided on the laser holder 41, and the oxygen bomb septum 41a is disposed between the top of the laser holder 41 and the bottom of the oxygen filling valve seat 31.

[0051] Specifically, a laser insulating pad 41b is provided inside the oxygen bomb diaphragm 41a. The laser insulating pad 41b is located between the top of the laser base 41 and the bottom of the oxygen filling valve seat 31. The laser insulating pad 41b and the oxygen bomb diaphragm 41a isolate the unnecessary heat conduction path between the laser base 41 and the oxygen filling valve seat 31, prevent the high temperature from affecting the oxygen filling mechanism, and extend the life of internal components.

[0052] In this embodiment, the laser insulating pad 41b is provided with a countersunk hole 41c, the size of which is adapted to the laser electrode 421, and the laser electrode 421 is disposed in the countersunk hole 41c. By embedding the laser electrode 421 into the countersunk hole 41c of the laser insulating pad 41b, the size of which is adapted to the electrode, ensures accurate coaxial positioning of the laser head 42 during installation, avoiding ignition failure due to misalignment. The countersunk hole structure also restricts the lateral displacement of the electrode, and together with the axial clamping force of the spring 42a, ensures the tightness of the electrical connection under vibration and temperature changes, stabilizes the power supply and laser energy output, and reduces safety hazards, such as the risk of electric sparks caused by poor contact.

[0053] In this embodiment, a glass upper pad 43a is provided at the top of the glass column 43, and the glass upper pad 43a is located between the bottom of the laser head 42 and the top of the glass column 43; a glass lower pad 43b is provided at the bottom of the glass column 43, and the glass lower pad 43b is located between the bottom of the glass column 43 and the laser cover 44.

[0054] In this embodiment, a spring 42a is provided on the laser head 42. The spring 42a is disposed near the outer surface of the laser head 42. One end of the spring 42a is connected to the top of the laser head 42, and the other end of the spring 42a is connected to the glass pad 43a.

[0055] By setting a spring 42a on the outer surface of the laser head 42, with one end connected to the top of the laser head and the other end abutting against the upper glass pad 43a, the heat conduction efficiency between the laser head and the glass column 43 is enhanced through elastic contact; the glass column 43, the upper glass pad 43a, and the lower glass pad 43b form a continuous heat conduction path, which quickly conducts the heat of the laser head to the oxygen bomb cartridge 2, avoiding the problem of incomplete sample combustion caused by local heat accumulation and improving the accuracy of experimental data.

[0056] In this embodiment, a glass pad 44a is provided on the laser cover 44, and the glass pad 44a is disposed near the top of the laser cover 44 and the bottom of the laser base 41.

[0057] The oxygen bomb shim 41a, laser insulating shim 41b, upper glass shim 43a, lower glass shim 43b, and outer glass shim 44a form a multi-layered physical barrier, blocking oxygen, moisture, and impurities from entering the internal circuitry and optical path of the laser head. The closed design of the laser cover 44, combined with the insulating properties of the glass pillar 43, enhances the equipment's waterproof and corrosion-resistant capabilities in humid environments or liquid operation scenarios, preventing short circuits and performance degradation of optical components, thus expanding its application to complex environments such as chemical and energy industries.

[0058] In this embodiment, the laser base 41 is provided with a number of mounting holes 41d, which are respectively located near the top edge of the laser base 41; the bottom of the oxygen bomb 11 is provided with a mounting seat 11e that matches the mounting holes 41d, and the laser base 41 is fixed to the bottom of the oxygen bomb 11 by a screw passing through the mounting holes 41d.

[0059] The laser mount 41 is fixed to the bottom of the oxygen bomb head 11 via the mounting hole 41d and the screw, replacing the existing integrated or nested structure. The laser head 42 can be quickly disassembled and replaced without professional tools, avoiding damage to other components during the disassembly process, significantly reducing maintenance costs (reducing component wear) and equipment downtime (improving efficiency), and avoiding interruptions in experiments / production.

[0060] In this embodiment, the baffle plate 11c is also provided with a through hole 111a. The through hole 111a is located near the central axis of the baffle plate 11c and is coaxial with the laser head 42 and the crucible 11d. The through hole 111a is strictly coaxial with the laser head 42 and the crucible 11d to ensure that the laser beam penetrates the baffle plate without obstruction and is directly focused on the sample in the crucible, avoiding ignition failure caused by energy loss or deviation.

[0061] In this embodiment, the oxygen warhead 11 and the mounting base 11e adopt an integrated structure. Example 2

[0062] like Figures 2 to 5 As shown, in a further improvement of the above embodiment 1,

[0063] An oxygen bomb large pressure ring 111 and a large sealing ring 112 are provided between the bottom of the oxygen bomb head 11 and the bomb cover 1. The large sealing ring 112 is located between the bottom of the bomb cover 1 and the oxygen bomb head 11, and the large pressure ring 111 is located between the top of the large sealing ring 112 and the bottom of the bomb cover 1.

[0064] Specifically, the laser electrode 421 is also provided with an electrode sealing ring 5, which is located between the outer surface of the laser electrode 421 and the countersunk hole 41c.

[0065] By adding a large pressure ring 111 and enlarging the sealing ring 112 and electrode sealing ring 5, the existing oxygen bomb's leakage risk, electrode reliability, and structural stability issues under high pressure are solved through a triple mechanism of "mechanical compression, material sealing, and stress dispersion".

[0066] By using electrode sealing ring 5, the technical challenge of "sealing and protecting electrical connections" in the laser ignition mechanism has been specifically overcome, enabling the equipment to adapt to complex scenarios such as high pressure, high temperature, humidity, and vibration (e.g., combustion experiments in chemical reactors and deep-sea exploration equipment), significantly improving the industrial applicability and safety of laser-ignited oxygen bombs.

[0067] Working principle of this utility model:

[0068] Oxygenation process: High-pressure sealed oxygen supply;

[0069] The oxygen filling mechanism is connected to an external oxygen source through the oxygen filling nozzle 32 at the top of the oxygen filling valve seat 31. The oxygen flows through the oxygen filling valve core 33 into the symmetrical oxygen filling channel 311 at the bottom of the oxygen filling valve seat 31, and is finally evenly injected into the oxygen bomb 2.

[0070] Ignition process: laser precision ignition;

[0071] The laser ignition mechanism is fixed to the bottom of the oxygen filling valve seat 31 via the laser seat 41. The laser emitted by the laser head 42 is conducted through the glass column 43 to the crucible 11d below (coaxial with the laser head) to ignite the sample.

[0072] Positioning and conductivity: The laser electrode 421 is embedded in the countersunk hole 41c of the laser insulating pad 41b. The size of the countersunk hole is adapted to the electrode to ensure accurate coaxial positioning during laser head installation. The electrode sealing ring 5 on the outer surface of the electrode fills the gap, which not only fixes the electrode to prevent displacement, but also isolates oxygen from contacting the electrode to avoid short circuit.

[0073] Energy conduction: The spring 42a on the outer surface of the laser head abuts against the upper glass pad 43a, enhancing the heat conduction efficiency between the laser head and the glass column through elastic contact; the glass column 43, the upper glass pad 43a, the lower glass pad 43b, and the outer glass pad 44a form a continuous heat conduction path, rapidly conducting the heat from the laser head to the oxygen bomb cartridge, ensuring complete combustion of the sample;

[0074] Structural protection: multi-layer sealing and anti-interference design;

[0075] Insulation and heat insulation: The oxygen bomb spacer 41a and the laser insulation pad 41b isolate the unnecessary heat conduction path between the laser seat and the oxygen filling valve seat 31, preventing high temperature from affecting the oxygen filling mechanism; the laser insulation pad 41b also serves as an insulating support for the electrode to prevent current leakage.

[0076] Environmental protection: The closed structure of the laser cover 44, combined with the insulating properties of the glass column, and multiple physical barriers such as the oxygen bomb gasket, laser insulation gasket, glass gasket, and electrode sealing ring, prevents moisture and impurities from entering the laser head, improving the equipment's waterproof and corrosion-resistant capabilities in humid and dusty environments.

[0077] Ease of maintenance: Modular design for quick assembly and disassembly;

[0078] The laser mount 41 is fixed to the bottom of the oxygen bomb head 11 via the mounting hole 41d and the screw, forming a modular structure. When the laser head needs to be replaced, the screw can be quickly disassembled without special tools, and the laser mount and internal laser head assembly can be disassembled separately, avoiding damage to other components when disassembling the traditional integrated structure, and significantly reducing maintenance costs and equipment downtime.

[0079] Adaptability to extreme environments;

[0080] High pressure and impact resistance: The multiple sealing structures (steel ring, pressure ring, sealing ring) of the oxygen filling mechanism and oxygen bomb head can withstand high temperature and high pressure (such as the impact of combustion and explosion). The mechanical support of the steel ring and pressure ring disperses stress and prevents component deformation; the rigid support structure of the laser outer cover and glass column protects the optical components from high pressure impact damage.

[0081] Vibration and temperature stability: The elastic clamping force of spring 42a and the positioning effect of countersunk hole 41c ensure that the laser head maintains a tight electrical connection when vibrating or experiencing sudden temperature changes, stably outputs laser energy, and avoids ignition failure or safety hazards caused by poor contact.
