Description

Technical Field

[0001] The present invention relates to the technical field of gas cylinder excitation, and in particular to a multi-mode micro-intelligent opening system for gas cylinders. Background Art

[0002] When the emergency life-saving equipment is inflated, an activator is needed to penetrate and stimulate the gas cylinder so that the carbon dioxide and other gases in the cylinder can be filled into the inflatable structure.

[0003] However, the gas cylinder excitation systems on the market still have problems such as incomplete functions, such as:

[0004] The existing anti-drowning life-saving bracelets on the market can only be manually opened to control the activation of the gas cylinder. However, this can only work when the person is conscious and calm. It is difficult for ordinary people to maintain a normal state to manually trigger when they suddenly fall into the water while working or playing near the water, or it is easy to make mistakes, so that they cannot complete the self-rescue action in time, making the device ineffective;

[0005] There are also devices on the market that use water-soluble tablets for triggering. Although this method can automatically open when falling into water, the disadvantage is that water will inevitably splash onto the tablets during water operations, causing false operation and opening.

[0013] (2) When set to automatic excitation mode:

[0014] (2.1) If the anti-falling function is selected, when the water sensor detects that the device has entered the water, it sends a water ingress signal to the controller, which ignites the fuel propulsion unit, causing the piston and the excitation shaft to be pressed downward under the thrust generated by the fuel propulsion unit, and finally pushes the excitation needle to pierce the gas cylinder to complete the inflation of the first aid equipment;

[0015] (2.2) If the anti-drowning function is selected, then:

[0019] If the current water temperature is not within the preset safety temperature threshold range and the current depth is not within the preset safety water depth threshold range, the controller ignites the fuel propulsion unit, causing the piston and the excitation shaft to be pressed downward under the thrust generated by the fuel propulsion unit, and finally pushes the excitation needle to pierce the gas cylinder to complete the inflation of the first aid equipment.

[0020] In a preferred embodiment of the present invention, in step (2.2.3), when the water temperature and the water depth exceed the safety threshold, the controller obtains the continuous accumulated time that the depth sensor is at an unsafe depth, and when the continuous accumulated time exceeds the preset safety time threshold, the controller ignites the fuel propulsion unit.

[0031] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-2 , the embodiment of the present invention includes:

[0033] A multi-mode micro-intelligent opening system for a gas cylinder is mainly used on small emergency inflatable equipment such as an anti-drowning life-saving bracelet. Its structure includes: a carbon dioxide cylinder 1, an air jet valve 2, a gas cylinder nozzle 3, a controller 4, a water immersion sensor 5, a temperature sensor 6, a depth sensor 7, and an excitation actuator 8. The excitation actuator includes an excitation valve body 81, a fuel propulsion unit 82, a manual boost block 83, an excitation shaft 84, a piston 85, and an excitation needle 86.

[0034] The jet valve is arranged at the bottle mouth of the carbon dioxide gas cylinder, and the gas cylinder nozzle is connected and arranged on the side wall of the jet valve.

[0035] The excitation valve body is connected to the carbon dioxide cylinder and / or the jet valve, and the piston is arranged in the excitation valve body in a liftable manner.

[0036] Further preferably, the carbon dioxide cylinder is threadedly connected to the jet valve, and the jet valve is threadedly connected to the excitation valve body.

[0037] The excitation shaft is connected to the piston, and its lower end is connected to an excitation needle for puncturing the mouth of the carbon dioxide cylinder. Its top extends upward to the outside of the excitation valve body and is connected to the manual booster block, so that the excitation shaft, piston and excitation needle can be driven down by the manual booster block to puncture the cylinder to release carbon dioxide.

[0038] Further preferably, the excitation shaft and the excitation needle are an integrated structure.

[0039] Further preferably, the excitation shaft is fixedly connected to the piston.

[0040] Further preferably, an adjusting thread is provided on the excitation shaft, and the piston is connected to the adjusting thread via an adjusting nut to adjust the position of the piston on the excitation shaft to meet different usage requirements.

[0041] The water immersion sensor, the temperature sensor and the depth sensor are electrically connected to the controller to obtain current environmental information. The controller is connected to the fuel propulsion unit through a fuse wire 87, so that the controller can detonate the fuel propulsion unit according to the detection signal of the sensor. The fuel propulsion unit is arranged in the excitation valve body above the piston, so that its own explosion / combustion is used as the opening power to push the piston close to the gas cylinder, so that the excitation needle pierces the gas cylinder. Among them, the controller can ignite / explode the fuel propulsion unit by common methods in the field such as electric current and laser, and the current circuit, laser generator and other equipment used for ignition / explosion and their connection methods are all common technical means in the field, and this case has not improved them.

[0042] In order to facilitate carrying, especially life-saving bracelets, it is necessary to make the size as small, light and easy to carry as possible. Therefore, an automatic dynamic explosive propulsion unit is used as the opening power output unit. The energy density generated by the automatic dynamic explosive propulsion unit is large, so the size can be made very small, and it is highly safe and stable, meeting current usage needs.

[0043] Among them, the sensors and controllers can adopt conventional sensor and controller models in the field as long as they can achieve the functions. This case does not involve improvements to the structure of sensors and controllers and the way they are connected with other structural equipment.

[0044] Further preferably, the controller includes a microprocessor and a power supply connected to the microprocessor.

[0045] Further preferably, the controller is integrated with or externally connected to a function selector, and the function selector can be used to select the desired usage mode and activation mode.

[0046] The excitation mode mainly includes manual excitation or automatic excitation mode.

[0047] The usage modes mainly include anti-drowning mode, swimming mode, etc. For example, if you want to achieve the effect of activating the trigger as soon as you fall into the water, you can choose the anti-drowning mode; if you are preparing to swim, you can turn on the swimming mode. After turning on the swimming mode, the temperature sensor will sense whether the water temperature is suitable for swimming. If it is not suitable, it can be activated. After the depth sensor senses that it is not within the set depth range and continues for a period of time, it will turn on the trigger.

[0048] Further preferably, the fuel propelling unit includes a fuel propelling shell and gunpowder or combustible gas arranged in the fuel propelling shell.

[0049] When the manual mode is selected for manual excitation of the excitation system, the user presses down the manual booster block to drive the excitation shaft and the piston downward, so that the excitation needle on the excitation shaft passes through the jet valve and punctures the gas cylinder, and the carbon dioxide in the gas cylinder is sprayed from the gas cylinder nozzle into the inflation structure of the first aid equipment connected to the excitation system.

[0050] When the automatic mode is selected for automatic excitation of the excitation system:

[0051] 1. Obtain environmental information through various sensors, and control the working behavior of the excitation actuator through the controller. Specifically: the immersion sensor can detect whether the excitation system and / or first aid equipment and / or human body are in water, the temperature sensor can detect whether the current water temperature is within the preset temperature range suitable for swimming, and the depth sensor can detect whether the excitation system and / or first aid equipment and / or human body are within the preset depth range;

[0052] 2. When the water sensor senses that it is in water, the temperature sensor senses that the current water temperature is not within the preset temperature range, and the depth sensor detects that the current depth is not within the preset water depth range (and the time at this depth exceeds the preset time threshold), the controller detonates the fuel propulsion unit through the lead wire to push the excitation needle to pierce the gas cylinder for inflation.

[0053] The beneficial effects of the multi-mode micro-intelligent opening system for gas cylinders of the present invention are: not only manual stimulation but also intelligent automatic stimulation can be adopted, and the functions are more comprehensive and can meet different usage requirements. At the same time, the stimulation system also has the characteristics of small size, high safety and strong stability, so that people can play an emergency self-rescue effect in all aspects such as water sports, water operations or prevention of falling into water.

[0054] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
