Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-3, the present embodiment provides an oxyhydrogen generating apparatus, which comprises a housing 1 and a water tank 2, wherein the housing 1 is configured with a hydrogen suction port 101, the water tank 2 is provided with a circulation inlet (not marked) and a circulation outlet (not marked), the oxyhydrogen generating apparatus further comprises a plurality of oxyhydrogen generating assemblies 3, the oxyhydrogen generating assemblies 3 are provided with a water inlet (not marked), a water return port (not marked) and a hydrogen outlet (not marked), the water inlets are respectively connected with the circulation outlet, the water return ports are respectively connected with the circulation inlet, and the hydrogen outlets are respectively connected with the hydrogen suction port 101.

Specifically, the oxyhydrogen generation apparatus of the present embodiment is configured with a plurality of oxyhydrogen generation assemblies 3 in a housing 1, and the oxyhydrogen generation assemblies 3 are oxyhydrogen generation modules in the oxyhydrogen generator of the conventional technology, which generally include electrodes and ion exchange membranes, and the specific structural form of the oxyhydrogen generation assemblies 3 is not limited herein. Because a plurality of oxyhydrogen generating assemblies 3 are arranged in parallel to generate gas simultaneously, a larger gas production rate can be obtained so as to meet the requirement of a user on the large gas volume. Meanwhile, for a single oxyhydrogen generation assembly 3, the size of the adopted ion exchange membrane is small, the volume of the single oxyhydrogen generation assembly 3 is small, and then a plurality of oxyhydrogen generation assemblies 3 can be arranged in the shell 1 to meet the requirement of portable use.

Wherein, in order to facilitate the installation of the internal components in the layout case 1, a plurality of hydrogen and oxygen generating modules 3 may be arranged at one side of the water tank 2, and a plurality of hydrogen and oxygen generating modules 3 are arranged side by side on the bottom plate of the case 1. In addition, it is also possible to provide the housings 10 arranged side by side on the bottom plate of the casing 1, with the oxyhydrogen generation assemblies 3 provided on the corresponding housings 10.

Furthermore, in order to perform gas-water separation treatment on the hydrogen generated by the hydrogen-oxygen generation assembly 3, the hydrogen-oxygen generation device is also provided with a gas-water separation assembly 4, and the gas-water separation assembly 4 is used for effectively separating and removing water in the gas flow. Specifically, the gas-water separation component is provided with a gas-water separation cavity; the hydrogen outlet is connected with the hydrogen suction port 101 through the gas-water separation cavity of the gas-water separation component.

Specifically, hydrogen generated by the oxyhydrogen generation assembly 3 is output into the gas-water separation cavity of the gas-water separation assembly through the hydrogen outlet, most of moisture falls into the bottom of the separation cylinder 41 due to the heavy weight of the moisture, and hydrogen is discharged from the gas-water separation cavity and is output through the hydrogen suction port 101.

And for the gas-water separation component, the gas-water separation component is arranged in the shell 1, and the specific structural form is as follows: the gas-water separation component comprises a separation cylinder 41, a floating body 42, an upper end cover 43 and a lower end cover 44; an air inlet pipe 431 and an air outlet pipe 432 are arranged on the upper end cover 43, a water outlet 441 is arranged on the lower end cover 44, the upper end cover 43 is arranged on the upper port of the separation cylinder 41, the lower end cover 44 is arranged on the lower port of the separation cylinder 41, the air-water separation cavity is formed between the separation cylinder 41 and the upper end cover 43 as well as between the separation cylinder 41 and the lower end cover 44, the floating body 42 is arranged in the separation cylinder 41, and a blocking part 421 for blocking the water outlet 441 is arranged at the bottom of the floating body 42.

Specifically, the hydrogen gas generated by the hydrogen-oxygen generation assembly 3 contains much moisture, and after entering the separation cylinder 41, most of the moisture falls into the bottom of the separation cylinder 41 due to the heavy weight of the moisture, and the hydrogen gas is discharged from the exhaust pipe 432. During the gas-water separation process, the floating body 2 blocks the water outlet 41 through the blocking portion 421 due to the gravity, so as to prevent or reduce the gas leakage from the water outlet 41. The separation cylinder 41 may be an independent component from the upper end cap 43 and the lower end cap 44, or the separation cylinder 41 may be an integral structure with the upper end cap 43 or the lower end cap 44.

As the usage time is prolonged, a certain amount of water is accumulated at the bottom of the separation cylinder 41, and as the amount of accumulated water at the bottom is increased, the buoyancy received by the floating body 42 is greater than the gravity of the floating body 42, so that the floating body 42 floats and leaves the drain port 441 under the buoyancy, thereby opening the drain port 441. After the water outlet 441 is opened, a positive pressure state is formed in the gas-water separation cavity due to the injection of hydrogen gas into the gas-water separation cavity, and accumulated water at the bottom of the gas-water separation cavity is quickly discharged through the water outlet 441 by utilizing the air pressure in the gas-water separation cavity. In a short time, the water level in the gas-water separation chamber will drop along with it, so that the gravity of the floating body 42 is greater than the buoyancy, and the floating body 42 falls down again and abuts against the drain port 441 to automatically close the drain port 441, thereby preventing hydrogen leakage.

The air inlet pipe 431 and the air outlet pipe 432 are arranged side by side, the air outlet direction of the air inlet pipe 431 faces downwards, and the air outlet direction of the air outlet pipe 432 faces upwards. Since the air outlet directions of the air inlet pipe 431 and the air outlet pipe 432 are arranged in the opposite direction, the air flow entering the air-water separation chamber from the air inlet pipe 431 can sufficiently separate moisture.

In addition, as for the expression entity of the blocking portion 421, a sealing plug may be adopted, that is, a sealing plug protruding downward is provided at the bottom of the floating body 42, and the sealing plug is the blocking portion 421. Specifically, when the gravity of the floating body 42 is greater than the buoyancy of the floating body, the sealing plug blocks the drain opening 441 at the bottom, and the sealing plug and the drain opening 441 form a sealing surface with a better airtight effect by combining the accumulated water at the bottom. When the buoyancy is larger than the gravity, the sealing plug follows the floating body 42

In a preferred embodiment, a pressure control module (not shown) is further connected to the exhaust pipe 432. Specifically, the pressure control module is arranged on the exhaust pipe 432 and can limit the output gas, so that the gas-water separation cavity is in a positive pressure state with a certain pressure value. In the positive pressure state, the floating body 42 in the gas-water separation chamber can further utilize the air pressure to more effectively seal and shield the water outlet 441, thereby improving the use reliability. Meanwhile, the positive pressure at a certain pressure value can also discharge the accumulated water quickly by the air pressure when the water outlet 441 is opened by the floating body 42. The representation entity of the pressure control module can be in various forms, such as: the pressure control module can be a backpressure valve connected to the exhaust pipe 432, or the pressure control module comprises a connecting air pipe and an aeration stone, the aeration stone is plugged in the connecting air pipe, and the connecting air pipe is connected with the exhaust pipe 432.

Based on the above technical solution, optionally, as shown in fig. 4, an oxygen suction port 102 is configured on the housing 1, and an oxygen outlet (not labeled) is provided at an upper portion of the water tank 2, and the oxygen outlet is connected with the oxygen suction port 102. Specifically, the oxygen suction port 102 can meet the requirement of a user for inhaling oxygen, and in order to achieve the oxygen removal, an independent gas-water separation assembly 4 can be additionally arranged between the oxygen suction port 102 and the oxygen outlet.
