Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary breathing equipment, in particular to a hydrogen-oxygen mixing atomizer. Background Art

[0002] Medical nebulizers are mainly used to treat various upper and lower respiratory system diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases occurring in the trachea, bronchi, alveoli and chest cavity. Nebulizer inhalation therapy is an important and effective treatment method for respiratory diseases. The nebulizer inhaler is used to atomize the liquid medicine into tiny particles. The medicine enters the respiratory tract and lungs through inhalation, thereby achieving the purpose of painless, rapid and effective treatment. There are three types of medical nebulizers, the mainstream types are compressed nebulizers (gas compressed air compressed nebulizers), ultrasonic nebulizers and mesh nebulizers. The gas compressed air compressed nebulizer uses compressed air to form a high-speed airflow through a small tube mouth. The negative pressure generated drives the liquid medicine to be sprayed onto the obstacle together. Under high-speed impact, the droplets splash around and become mist particles and are sprayed out from the outlet pipe.

[0003] Currently, there are two hydrogen output modes for hydrogen-oxygen machines that produce hydrogen and oxygen through electrolysis, one is pure hydrogen output, and the other is hydrogen-oxygen mixed output. The hydrogen absorption tube for pure hydrogen output is a small hole that is inserted into the nostrils. Although some air will be inhaled through the gap next to it, users are prone to insufficient oxygen supply and hypoxia. Hydrogen-oxygen mixed output can solve the hypoxia problem, but the volume ratio of hydrogen to oxygen in the hydrogen-oxygen mixed gas is 2:1, and according to theoretical calculations, the explosion limit of hydrogen is 4%-75.6% (volume concentration), so although the hydrogen-oxygen mixed method is effective, it is not very safe.

DETAILED DESCRIPTION

[0026] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Example 1

[0028] like Figure 1-5 As shown, an embodiment of the utility model provides a hydrogen-oxygen mixing atomizer, comprising an atomizing cup 7, a main shell, a compressor unit and a gas mixing tank 19 integrated in the main shell, the output end of the gas mixing tank 19 is connected to the input end of the compressor unit, the output end of the compressor unit is connected to the atomizing cup 7, and the two input ends of the gas mixing tank 19 are respectively provided with an oxygen interface 11 and a hydrogen interface 12, the oxygen interface 11 is connected to the input end of the gas mixing tank 19 through an oxygen flow limiting valve 17, and the hydrogen interface 12 is connected to the input end of the gas mixing tank 19 through a hydrogen flow limiting valve 18; the ventilation volume ratio between the oxygen flow limiting valve 17 and the hydrogen flow limiting valve 18 is greater than 24:1.

[0029] Specifically, oxygen and hydrogen are mixed in the gas mixing tank 19 to form a hydrogen-oxygen mixed gas after passing through the oxygen flow limiting valve 17 and the hydrogen flow limiting valve 18, and the volume concentration of hydrogen in the hydrogen-oxygen mixed gas is not greater than 4%; the hydrogen-oxygen mixed gas is transmitted to the compressor unit through the output end of the gas mixing tank 19. The gas mixing tank 19 can be a three-way valve, or a hydrogen-oxygen mixed tank can be used to mix oxygen and hydrogen in the tank body and then output. Figure 3As shown, the hydrogen-oxygen mixing atomizer further includes an oxygen pressure regulating valve 13 and a hydrogen pressure regulating valve 14, the oxygen interface 11 is connected to the oxygen flow limiting valve 17 through the oxygen pressure regulating valve 13, and the hydrogen interface 12 is connected to the hydrogen flow limiting valve 18 through the hydrogen pressure regulating valve 14, and the oxygen pressure regulating valve 13 and the hydrogen pressure regulating valve 14 make the oxygen and hydrogen entering the mixing tank 19 have the same pressure. Optionally, an oxygen pressure gauge 15 and a hydrogen pressure gauge 16 are respectively provided corresponding to the oxygen pressure regulating valve 13 and the hydrogen pressure regulating valve 14.

[0030] When in use, since the oxygen and hydrogen outputted by the oxygen source such as the oxygen generator and the hydrogen source such as the hydrogen generator have the same pressure respectively by the pressure regulating valve, the amount of gas passing through the flow limiting valve per unit time is related to the aperture size. When the ventilation volume ratio between the oxygen flow limiting valve 17 and the hydrogen flow limiting valve 18 is greater than 24:1, that is to say, the hydrogen concentration in the hydrogen-oxygen mixed gas in the mixing tank 19 will not be greater than 4%; thereby ensuring that the hydrogen-oxygen mixed gas is in an absolutely safe state, avoiding the use of a flow regulating valve to adjust the output ratio of oxygen and hydrogen. The flow regulating valve cannot guarantee absolute stability and safety, and manual adjustment is also prone to errors, which puts the equipment in a dangerous and uncontrollable state. The use of a flow limiting valve limits the oxygen and hydrogen ratio within a safe and controllable range through a physical structure, thereby achieving an absolutely safe output state of the equipment.

[0031] like Figure 2 , 3 As shown, the compressor unit includes a driving motor 26, a compression cylinder 22, and a guide fixing seat 23 connected to the compression cylinder 22. The driving motor 26 is arranged in the main housing through a motor mounting seat 27. A cam 25 is arranged at one output end of the driving motor 26. The cam 25 drives a piston arranged in the guide fixing seat 23 through a connecting rod 24, and the piston performs work on the hydrogen-oxygen mixed gas in the compression cylinder 22.

[0032] Specifically, a heat dissipation metal sheet group 28 is sleeved on the driving motor 26 , and an impeller 29 is disposed at the other output end of the driving motor 26 , and the impeller 29 corresponds to the heat dissipation metal sheet group 28 .

[0033] like Figure 1 As shown, the main shell includes an upper shell 1 and a lower shell 2, and the upper shell 1 and the lower shell 2 are fixedly installed by a plurality of screw seats 4 and screws. At least one air vent 3 is opened on the side of the upper shell 1 and the lower shell 2, and the air vent 3 corresponds to the heat dissipation metal plate group 28.

[0034] Optionally, the hydrogen-oxygen mixing atomizer further includes a power cord 5 and a display and control device 9, and the power cord 5, the display and control device 9 and the driving motor 26 are interconnected.

[0035] Optionally, the hydrogen-oxygen mixing atomizer further includes a hose 6 and an atomizing hood 8, wherein one end of the hose 6 is connected to the compression cylinder 22 via a hose connector 10, and the other end is disposed at the lower end of the atomizing cup 7, and the atomizing hood 8 is disposed at the upper end of the atomizing cup 7.

[0036] like Figure 2 , 3 As shown, an electronic flow meter 21 and a safety valve 20 are provided on the air intake pipe between the output end of the mixing tank 19 and the compression cylinder 22, and the output end of the compression cylinder 22 is connected to the hose connector 10 through a pressure pipe.

[0037] Optionally, the electronic flow meter 21 is electrically connected to the display and control device 9 to display in real time the flow rate, pressure and other parameters of the hydrogen-oxygen mixed gas entering the compression cylinder 22. A one-way valve and a pressure gauge can be set at the pressure pipe, the air intake pipe and other positions, and the pressure value of the hydrogen-oxygen mixed gas output from the compression cylinder is realized by controlling the speed of the driving motor. The pressurized hydrogen-oxygen mixed gas is introduced into the nebulizer cup to atomize the medicine, and the user wears the nebulizer mask for nebulization treatment.

[0038] Hydrogen molecules have been proven to be very safe for the human body, but there is an unavoidable safety issue when hydrogen and oxygen are mixed. The combustion range and detonation range of hydrogen mixed with air are 4-75.6% (V / V) and 18-59% (V / V), respectively, and the combustion range and detonation range of hydrogen mixed with oxygen are 4.65-94% (V / V) and 18.3-58.9% (V / V), respectively. The ignition energy is only 0.02mj, and the flame speed is 270cm / s. The current hydrogen-oxygen mixed gas will burn and explode when it encounters an open flame or static spark. In order to better and more safely provide oxygen and hydrogen to patients at the same time, combining the advantages of the two gases, the above safety hazards must be eliminated.

[0039] The hydrogen-oxygen mixed atomizer of the embodiment of the utility model completely solves the above-mentioned safety problems and achieves intrinsic safety. The volume concentration of hydrogen in the hydrogen-oxygen mixed gas provided to the user is guaranteed to be within 4% by physical current limiting, which completely eliminates the risk of explosion. Specifically, the utility model adopts the following technical solutions to achieve intrinsic safety: an oxygen pressure regulating valve and a hydrogen pressure regulating valve are respectively installed on the oxygen interface and the hydrogen interface, so that oxygen and hydrogen have the same pressure when input, and an oxygen flow limiting valve and a hydrogen flow limiting valve are respectively set at the output ends of the oxygen pressure regulating valve and the hydrogen pressure regulating valve, and the ventilation volume ratio between the oxygen flow limiting valve and the hydrogen flow limiting valve is greater than 24:1; the volume concentration of hydrogen in the hydrogen-oxygen mixed gas output by the hydrogen-oxygen mixed atomizer is constant and not greater than 4%, and even if it encounters a fire source, it will not cause an explosion.

[0040] The utility model discloses a hydrogen-oxygen mixed atomizer, by respectively arranging pressure regulating valves at the oxygen interface and the hydrogen interface so that the input gas pressures of oxygen and hydrogen are the same, then a flow limiting valve is used to mix oxygen and hydrogen in a gas mixing tank to form a hydrogen-oxygen mixed gas, and a compression cylinder is used to further pressurize the hydrogen-oxygen mixed gas and then drive an atomizing cup to realize the atomization treatment function of the medicine, and the flow limiting valve makes the gas volume ratio of oxygen and hydrogen greater than 24:1, that is, the volume concentration of hydrogen in the hydrogen-oxygen mixed gas is constant and not greater than 4%, and even if a fire source is encountered, it will not cause an explosion; the safety hazard of hydrogen-oxygen mixed gas can be completely eliminated, so that the oxygen-hydrogen mixed atomization treatment program can be popularized more quickly, the hydrogen-oxygen mixed gas has stronger permeability than single oxygen and increases the anti-inflammatory effect of hydrogen, and has a better treatment effect on lung diseases, and the use of a flow limiting valve to control the mixing ratio of oxygen and hydrogen is safer and has lower cost.

For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
