For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The water mist hydrogen production device provided in an embodiment of the present invention includes: a water storage mechanism 100, an atomization mechanism 200 and a storage container 300, the water storage mechanism 100 is connected to the atomization mechanism 200, the storage container 300 is used to store hydrogen production materials 310, and is connected to the atomization mechanism 200; the atomization mechanism 200 includes an atomization element and a control component connected to the atomization element signal.

[0028] Specifically, the water storage mechanism 100 is detachably connected to the atomizing mechanism 200 and the storage container 300, respectively. The atomizing mechanism 200 includes an atomizing housing 210, and the upper end of the atomizing housing 210 is provided with an atomizing groove for accommodating water, and the atomizing member includes an atomizing sheet 220, and the atomizing sheet 220 is installed at the bottom of the atomizing groove. The control component is arranged in the atomizing housing 210 and is connected to the atomizing sheet 220 signal. The part where the water storage mechanism 100 is connected to the atomizing mechanism 200 is provided with a water outlet. During the hydrogen production process, the water storage mechanism 100 is connected to the atomizing housing 210, the water outlet is communicated with the atomizing groove, the atomizing groove is communicated with the storage container 300, the water in the water storage mechanism 100 enters the atomizing groove, the control component controls the atomizing sheet 220 to atomize the water, and the water mist 121 generated by the atomization enters the storage container 300, and the water mist 121 reacts with the hydrogen production material 310 in the storage container 300 to produce hydrogen.

[0029] Furthermore, the water storage mechanism 100 includes a water reservoir 110, which is located between the atomization mechanism 200 and the storage container 300; an air pipeline 120 is provided in the middle of the water reservoir 110, and the air pipeline 120 is connected to the atomization mechanism 200 and the storage container 300 respectively.

[0030] The exterior of the water reservoir 110, the exterior of the accumulator 300 and the exterior of the atomizing housing 210 are all cylindrical, the lower end of the water reservoir 110 is connected to the atomizing housing 210, and the upper end of the water reservoir 110 is connected to the accumulator 300. The lower end of the accumulator 300 is provided with an opening for the gas pipeline 120 to enter, and the upper end of the accumulator 300 is provided with an exhaust port for the discharge of hydrogen. The gas pipeline 120 penetrates the water reservoir 110 along the axial direction of the water reservoir 110, the lower end of the gas pipeline 120 extends out of the lower end surface of the water reservoir 110, and the upper end of the gas pipeline 120 extends out of the upper end surface of the water reservoir 110. When the water reservoir 110 is connected to the atomizing shell 210 and the accumulator 300, the lower end of the gas pipeline 120 is located in the atomizing groove and opposite to the atomizing sheet 220, and the upper end of the gas pipeline 120 extends into the accumulator 300 through the opening on the accumulator 300, so that the atomizing groove and the accumulator 300 are connected through the gas pipeline 120.

[0031] During the hydrogen production process, the water in the water reservoir 110 enters the atomizing tank under the action of gravity, and the control component controls the atomizing sheet 220 to atomize the water. The water mist 121 generated by the atomization enters the storage container 300 through the gas pipeline 120. The water mist 121 reacts with the hydrogen production material 310 in the storage container 300 to generate hydrogen, and the generated hydrogen can be discharged through the exhaust port on the storage container 300. The water reservoir 110 is located between the atomizing mechanism 200 and the storage container 300, making the structure of the water mist hydrogen production device more compact.

[0032] Furthermore, the water reservoir 110 and the atomization mechanism 200 are detachably connected.

[0033] The upper end of the water reservoir 110 is detachably connected to the accumulator 300, and the lower end of the water reservoir 110 is detachably connected to the atomizing housing 210. Specifically, the lower end of the water reservoir 110 can be connected to the atomizing housing 210 by means of a clamping connection or a bolt connection.

[0034] When water needs to be added to the water reservoir 110 , the water reservoir 110 can be removed from the atomizing housing 210 , and the water inlet cap 160 can be opened to facilitate adding water to the water reservoir 110 .

[0035] Furthermore, a water supply pipeline 130 is provided on the end surface of the water reservoir 110 opposite to the atomization mechanism 200 , the water supply pipeline 130 is provided with a switch assembly 140 , and the atomization mechanism 200 is provided with an opening piece for opening the switch assembly 140 .

[0036] like Figure 1 As shown, the water delivery pipeline 130 penetrates the lower end surface of the water reservoir 110, and the axis of the water delivery pipe is parallel to the axis of the water reservoir 110. The switch assembly 140 is arranged at one end of the water delivery pipeline 130 located in the water reservoir 110. When the switch assembly 140 is not in contact with the opening member, the switch assembly 140 closes the water delivery pipeline 130 to prevent the water in the water reservoir 110 from flowing out.

[0037] The opening member includes a pin 240, which is rod-shaped and arranged in a vertical direction and fixedly mounted at the bottom of the atomizing tank.

[0038] When the water reservoir 110 is installed on the atomizing housing 210, the ejector pin 240 is inserted into the water delivery pipeline 130, and the switch assembly 140 is turned on, the water in the water reservoir 110 enters the atomizing tank through the water delivery pipeline 130, and the atomizing sheet 220 atomizes the water in the atomizing tank.

[0039] Furthermore, the switch assembly 140 includes a movable valve 141 and an elastic member. The movable valve 141 is located in the water reservoir 110 . The elastic member is respectively connected to the movable valve 141 and the water pipeline 130 . The elastic member enables the movable valve 141 to have a tendency to close the water pipeline 130 .

[0040] like Figure 1 As shown, the movable valve 141 is provided at one end of the water pipeline 130 located in the water reservoir 110, and is used to close or open the water pipeline 130. The elastic member may include a rubber strip or a coil spring 142, etc. In this embodiment, the elastic member includes a coil spring 142, which is located in the water pipeline 130, one end of the coil spring 142 is connected to the movable valve 141, and the other end of the coil spring 142 is connected to the inside of the water pipeline 130. In the absence of external force, the coil spring 142 pulls the movable valve 141 to close the water pipeline 130, preventing the water in the water reservoir 110 from flowing out through the water pipeline 130.

[0041] When the water reservoir 110 is installed on the atomizing housing 210, the ejector pin 240 extends into the water delivery pipeline 130 and lifts up the movable valve 141, so that the movable valve 141 opens the water delivery pipeline 130. When the movable valve 141 is lifted up, the coil spring 142 is in a stretched state. When the ejector pin 240 cancels the force acting on the movable valve 141, the movable valve 141 automatically closes the water delivery pipeline 130 under the action of the restoring force of the coil spring 142.

[0042] Furthermore, a one-way air inlet pipe 150 is provided on the end surface of the water reservoir 110 opposite to the atomization mechanism 200 , and the one-way air inlet pipe 150 is used to allow the gas in the atomization mechanism 200 to enter the water reservoir 110 .

[0043] like Figure 1 As shown, the one-way air inlet pipe 150 is fixedly installed at the bottom end of the water reservoir 110 and penetrates the water reservoir 110, and the axis of the one-way air inlet pipe 150 is parallel to the axis of the water reservoir 110. A water-proof cotton core is arranged in the one-way air inlet pipe 150, and the water-proof cotton core allows external gas to enter the water reservoir 110 through the one-way air inlet pipe 150, and prevents the water in the water reservoir 110 from flowing out from the one-way air inlet pipe 150.

[0044] During the hydrogen production process, the air in the atomization tank can enter the water reservoir 110 through the one-way air inlet pipe 150, and the water in the water reservoir 110 enters the atomization tank through the water delivery pipeline 130. The setting of the one-way air inlet pipe 150 prevents negative pressure from being generated in the water reservoir 110 and affecting the outflow of water in the water reservoir 110.

[0045] Furthermore, the lower end of the gas transmission pipeline 120 extends out of the water reservoir 110 .

[0046] like Figure 1As shown, the lower end of the gas pipeline 120 and the lower end of the one-way air inlet pipe 150 both extend from the lower end of the water reservoir 110, and the extended length of the gas pipeline 120 is greater than the extended length of the one-way air inlet pipe 150. When the water reservoir 110 is mounted on the atomizing housing 210, the gas pipeline 120 and the atomizing sheet 220 are opposite and spaced apart, and the lower end surface of the gas pipeline 120 is lower than the lower end surface of the one-way air inlet pipe 150.

[0047] The water in the water reservoir 110 enters the atomizing tank through the water delivery pipe 130. Since the water reservoir 110 is closed, the one-way air inlet pipe 150 will guide the gas in the atomizing tank into the water reservoir 110, so that the water in the water reservoir 110 can continue to flow into the atomizing tank. Since the lower end surface of the air delivery pipe 120 above the atomizing sheet 220 is lower than the lower end surface of the one-way air inlet pipe 150, when the liquid level in the atomizing tank is higher than the lower end of the air delivery pipe 120, the liquid in the atomizing tank will seal the lower end of the air delivery pipe 120, and the gas in the air delivery pipe 120 cannot enter the atomizing tank. Therefore, when all the air in the atomizing tank enters the water reservoir 110 through the one-way air inlet pipe 150, the air in the water reservoir 110 cannot increase any more and a negative pressure is generated, so that the water in the water reservoir 110 no longer enters the atomizing tank through the water delivery pipe 130, and the liquid level in the air delivery pipe 120 is prevented from being too high.

[0048] Furthermore, a water inlet is provided at the end surface of the water reservoir 110 opposite to the atomization mechanism 200 , and a water inlet cover 160 is provided at the water inlet, and the water inlet cover 160 is detachably connected to the water reservoir 110 .

[0049] like Figure 1 As shown, the water inlet is arranged at the lower end surface of the water reservoir 110, and the water inlet cover 160 can be connected to the water reservoir 110 by threaded connection. A sealing ring is arranged on the water inlet cover 160 to prevent the water in the water reservoir 110 from leaking from the water inlet.

[0050] When water needs to be added to the water reservoir 110, the water inlet cap 160 is removed from the water reservoir 110. After the water is added, the water inlet cap 160 is tightened on the water reservoir 110 to prevent water from flowing out. When the water reservoir 110 is connected to the atomizing housing 210, the water inlet cap 160 is located in the atomizing tank. When water leaks from the water inlet cap 160, the leaked water enters the atomizing tank to avoid waste.

[0051] Furthermore, the water mist hydrogen production device also includes a filtering mechanism, and the filtering mechanism is connected to the storage container 300.

[0052] Specifically, the filtering mechanism includes a filter 410, and a filter cotton 420 is arranged inside the filter 410. The filter 410 is located at one end of the accumulator 300 away from the water reservoir 110, and is connected to the water reservoir 110. The lower end of the filter 410 is communicated with the exhaust port of the accumulator 300, and the upper end of the filter 410 is provided with an exhaust pipe 430, and the exhaust pipe 430 is communicated with the inside of the filter 410.

[0053] The water mist 121 reacts with the hydrogen-producing material 310 in the storage container 300 to generate hydrogen, and the hydrogen enters the filter mechanism through the exhaust port, is filtered by the filter cotton 420, and is discharged through the exhaust pipe 430.

[0054] Furthermore, the control component includes an adjusting knob 230 and a control circuit, and the control circuit is connected to the adjusting knob 230 and the atomizing sheet 220 respectively.

[0055] Specifically, the adjusting knob 230 is installed on the atomizing housing 210 , and the control circuit is located in the atomizing housing 210 and is respectively connected to the adjusting knob 230 and the atomizing sheet 220 by signals. Figure 2 The circuit schematic diagram of the water mist hydrogen production device provided in the embodiment of the present invention, specifically, the reed switch is used to detect the water level, the two LED lights (LED2, LED1) indicate the working state and the water shortage state respectively, and the R5 potentiometer is used to adjust the power. The oscillation circuit is composed of a power transistor Q1 and a peripheral capacitor and inductor to form a three-point oscillation circuit. Since the atomizer 220 itself can be regarded as a crystal oscillator with a natural frequency, it oscillates after being excited by the oscillation circuit. This oscillation signal is fed back to the oscillation circuit through the coupling capacitor, so that the resonant frequency of the oscillation circuit is the natural frequency of the atomizer 220. The potentiometer R5 is adjusted by adjusting the knob 230 to change the base current (voltage) of the transistor Q1 to change the voltage across the atomizer 220.

The water storage mechanism 100 is connected to the atomizing mechanism 200. The storage tank 300 is used to store hydrogen production materials 310 and is connected to the atomizing mechanism 200. The atomizing mechanism 200 includes an atomizing element and a control component connected to the atomizing element signal. When using the water mist hydrogen production device provided in the embodiment of the present invention to prepare hydrogen, the water in the water storage mechanism 100 enters the atomizing mechanism 200, the atomizing element atomizes the water, and the water mist 121 generated by the atomization enters the storage tank 300. The water mist 121 entering the storage tank 300 reacts with the hydrogen production material 310 in the storage tank 300 to produce hydrogen.

[0058] Compared with the prior art, the water mist hydrogen production device provided in the embodiment of the present invention can control the atomization amount of the atomizing element through a control component, thereby controlling the hydrogen production rate by controlling the atomization amount and reducing the situation where a large amount of heat is generated locally; when it is necessary to stop the reaction, the atomizing element is controlled by the control component to stop atomization, so that the hydrogen production material 310 is no longer in contact with the water mist 121, thereby stopping the reaction.
