[0026] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way restricts the present invention and its application or use. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] It should be noted that the terms used herein are only for describing the specific implementation manners and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations.

[0028] Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not require further discussion in subsequent drawings.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description.

[0032] Embodiment 1

[0033] As Figure 1 and 2 shown, the present invention provides a compact portable hydrogen-oxygen generator, which includes a housing 1, an end cover 2 buckled on the upper end of the housing 1 for air outlet, and a bottom cover 15 buckled on the lower end of the housing 1.

[0034] Inside the housing 1, a battery module for power supply, an electrolytic cell module for generating hydrogen / oxygen mixed gas, a water filtration cell 4 for filtering moisture, and a multi-stage filtration baffle for further filtering the gas are sequentially arranged from bottom to top. As shown in the figure, the multi-stage filtration baffle is two-stage. The first-stage filtration baffle 5 is adjacent to the water filtration cell 4, and a flame retardant core 7 is provided between the second-stage filtration baffle 6 and the air outlet 3 provided in the end cover 2.

[0035] A water level monitoring module is further provided between the electrolytic cell module and the water filtration cell 4. The water level monitoring module includes a high water level indication mark 8 and a low water level float 9 connected to a sensor. The water level monitoring module is arranged on the electrode 10 to monitor the addition amount and usage amount of the electrolyte.

[0036] The water filtration cell 4 and the end cover 2 are locked by screwing. A receiving cavity for accommodating the multi-stage filtration baffle is formed therebetween. Specifically, water is used to be contained in the water filtration cell 4. A hollow boss is provided in the middle thereof. The structure of the first-stage filtration baffle 5 is a disc-shaped structure with a centering indentation corresponding to the boss of the water filtration cell 4 in the middle. Only an indentation structure without a hollow opening is provided in the middle thereof. A slightly convex outer edge is provided around the disc. At least one through hole for the hydrogen / oxygen mixed gas to pass through is provided on the disc-shaped main body (non-middle position) thereof. A plurality of auxiliary baffle pieces are selectively provided at the lower end of the disc-shaped main body. The auxiliary baffle pieces can be seen from the back view Figure 2 thereof.

[0037] The middle part of the boss abuts against the centering indentation of the first-stage filtration baffle 5 and is sealed with the middle part and the periphery thereof, ensuring that the gas generated by the reaction passes through the water pool of the water filtration cell 4 and is filtered layer by layer through the airway on the side.

[0038] The structure of the second-stage filtration baffle 6 is the same as or different from that of the first-stage filtration baffle 5. The structure of the second-stage filtration baffle 6 is a screen-type disc composite structure with a plurality of ventilation holes. The top disc has a screen with a plurality of ventilation holes, and at least one main ventilation hole is provided on the remaining discs. A plurality of discs are arranged staggeredly to form a filtration structure. The second-stage filtration baffle 6 shown in the figure is a composite structure in which two parts are inlaid and closed. The hydrogen / oxygen mixed gas with water vapor is condensed into water vapor through the multi-layer filter plates, making the gas exiting from the outlet more dry.

[0039] In this embodiment, an electrode 10 for reaction is provided in the electrolytic cell module. The electrode 10 is screwed through the baffle between the electrolytic cell module and the battery module and the fixing hole on the bottom cover 15 by a screw 11.

[0040] Embodiment 2

[0041] As Figure 3 shown, different from Embodiment 1, in this embodiment, two electrode structures are provided. In order to increase the reaction rate, the electrode 10 and the reinforcing electrode 12 are used in combination. Between the two electrodes, they are separated by an insulating ring 13.

[0042] In addition, in this embodiment, it can be clearly seen that the water filter 4 has a large accommodation cavity for storing water and a ventilation pipe connected thereto, which can extend the flow path of the reaction gas and make the filtration more thorough. Similarly, the secondary filtration baffle 6 adopts a side-hole-shaped structure staggered from the primary filtration baffle 5.

[0043] Embodiment 3

[0044] As Figure 4 shown, different from Embodiment 1, in this embodiment, the primary filtration baffle 5 is a plate-shaped filter plate, and a ventilation part is provided on one side thereof. The structure of the secondary filter plate 6 is substantially the same as that of Embodiment 1. In this embodiment, a tertiary filtration baffle 16 is also provided, and the hydrogen / oxygen mixed gas removes water vapor through layer-by-layer condensation. A sealing ring 17 is also provided between the water filtration tank 4, the end cover 2 and the housing 1. When the end cover 2 is tightened and locked with the water filtration tank 4, the sealing ring 17 plays a sealing role.

[0045] During use, water and electrolyte can be injected from the air outlet 3, and then the water level monitoring module is used to monitor whether the water level in the electrolytic cell is appropriate. The power supply connector 22 contacts the battery 14, and the entire device is controlled by turning on the power button 19 to connect to the circuit board. The electrode 10 starts to react and generate gas in the electrolyte module. The electrode 10 is fixed to the bottom cover 15 through the gasket 20 and the screw in sequence by the screw 11. In order to stand upright on a desktop or other positions, an anti-slip pad 18 is provided at the lower end of the bottom cover 15.

[0046] Turn on the power button 19 to start the hydrogen-oxygen generator to generate gas. The hydrogen / oxygen mixed gas mixed with water vapor is generated from the electrolytic cell module and enters the water filter 4, and then enters the multi-stage filtration baffle through the air duct. The meandering ventilation air duct formed between the multi-stages causes the water vapor to condense on the filtration baffle and fall back into the electrolytic cell. The relatively dry hydrogen / oxygen mixed gas is finally led out from the air outlet 3 through the flame arrester core 7 for the user to inhale.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
