Referring to FIG. 1, the hydrogen generating device 100 according to an embodiment includes a powder storage unit 120 in which powder 20 is stored, and a reaction liquid 10 for generating hydrogen gas by reacting with the powder 20 is stored. Opening or closing the reaction unit 110, the powder passage 130 connecting the powder storage unit 120 and the reaction unit 110, and the powder passage 130 so that the powder 20 is supplied to the reaction unit 110 The stopper 140 and the hydrogen passage 150 through which hydrogen gas generated in the reaction unit 110 moves may be included.

The powder storage unit 120 may include a material composed of specific elements capable of generating hydrogen by reacting with a reactant such as water. A material composed of specific elements may be a metal in the form of powder 20 .

For example, substances composed of certain elements are alkali metals (lithium, sodium, potassium, rubidium, cesium, francium, etc.), alkaline earth metals (beryllium, magnesium, potassium, strontium, barium, radium, etc.), group 13 elements (boron, etc.) , aluminum, gallium, indium, etc.) or a combination thereof. According to an embodiment, the powder 20 included in the powder storage unit 120 may be at least one of aluminum (Al) powder, magnesium (Mg) powder, and calcium (Al) powder.

The reaction unit 110 may include a reaction liquid 10 that reacts with the powder 20 to generate hydrogen gas. The reaction liquid 10 may be a liquid composed of molecules containing hydrogen atoms to generate hydrogen by reacting with the powder 20 . According to one embodiment, the reaction liquid 10 may be water or distilled water.

Those skilled in the art can understand that the reaction liquid 10 and the powder 20 are not limited to those described above, and may be various materials capable of generating hydrogen gas by reacting with each other.

The powder storage unit 120 and the reaction unit 110 may be connected by a powder passage 130 . The powder passage 130 may be formed so that the powder 20 can be supplied to the reaction unit 110 . When the powder 20 is supplied to the reaction unit 110 through the powder passage 130, a chemical reaction between the powder 20 and the reaction liquid 10 occurs in the reaction unit 110, and thus hydrogen gas is generated. It can be.

According to an embodiment, the reaction in which hydrogen gas is generated may be an oxidation/reduction reaction in which the metal powder 20 is oxidized and the reaction solution 10 is reduced. According to the reaction of the powder 20 and the reaction solution 10, hydrogen gas and ions and/or precipitates may be formed. When 1 g of aluminum powder reacts with water, 1.3 L (liter) of hydrogen gas can be produced.

According to one embodiment, the hydrogen gas generated in the reaction unit 110 may move toward the hydrogen passage 150 through the open powder passage 130 . However, it is not limited thereto.

The stopper 140 may open or close the powder passage 130 connecting the powder storage unit 120 and the reaction unit 110 . The shape of the stopper 140 may be a simple rectangular shape as shown in FIG. 1, but is not limited thereto.

According to embodiments, the stopper 140 may be inserted into the powder passage 130 to close the powder passage 130 . In addition, the stopper 140 may have a shape that covers one side of the powder passage 130 without any gaps. In addition, the stopper 140 may be formed in at least a portion of the powder passage 130, and may have a membrane shape or a flange shape capable of opening and closing the powder passage 130.

When the hydrogen generating device 100 is not operating, the stopper 140 closes the powder passage 130 to prevent mixing of the powder 20 and the reaction liquid 10 to prevent a reaction from occurring. In addition, the stopper 140 may open the powder passage 130 when the hydrogen generating device 100 is operated so that the powder 20 is supplied to the reaction unit 110 so that a reaction occurs.

Accordingly, unnecessary hydrogen gas can be prevented from being generated when the hydrogen generating device 100 is not in use, and hydrogen gas can be generated only when the hydrogen generating device 100 is used. That is, an appropriate amount of the powder 20 can be controlled to be supplied to the reaction unit 110 only when hydrogen gas is needed, so that the powder 20 and the reaction liquid 10 can be prevented from being mixed at once.

The hydrogen passage 150 may be a hydrogen gas passage through which the hydrogen gas generated in the reaction unit 110 is discharged to the outside of the hydrogen generating device 100 . One end of the hydrogen passage 150 may be connected to at least one of the powder storage unit 120 , the powder passage 130 and the reaction unit 110 .

The hydrogen passage 150 may extend from one end of the hydrogen passage 150 to the other end opposite to the end of the hydrogen passage 150, and may communicate with the outside of the hydrogen generating device 100. The other end of the hydrogen passage 150 may be connected to a mouthpiece formed at one end of the hydrogen generating device 100.

The hydrogen gas generated in the reaction unit 110 moves along the hydrogen passage 150 and is discharged to the outside of the hydrogen generating device 100, and the user sucks one end of the hydrogen generating device 100 to the hydrogen generating device ( 100) It is possible to inhale hydrogen gas discharged to the outside.

The powder passage 130 may be opened or closed by a mechanical mechanism as well as opened or closed by an electrical mechanism. A detailed description of this will be described later.

Although not shown in FIG. 1, the hydrogen generating device 100 may further include at least one through hole communicating the outside and the inside of the hydrogen generating device 100 to facilitate the flow of gas such as air and hydrogen. .

External air may flow into the hydrogen generating device 100 through the through hole.

2 is an enlarged cross-sectional view of the inside of a hydrogen generating device according to an embodiment.

Referring to FIG. 2 , a reaction unit 110 , a powder storage unit 120 , a powder passage 130 , a stopper 140 and a hydrogen passage 150 are shown.

The hydrogen generating device 100 according to one embodiment may further include an elastic element 142 . One end of the elastic element 142 may be fixed to at least a portion of the first protrusion 151 protruding from the inner wall of the hydrogen passage 150 toward the center of the hydrogen passage 150, and at least one of the elastic elements 142 Some may be combined with the stopper 140. However, the fixing method of the elastic element 142 is not limited thereto, and it can be understood by those skilled in the art that the elastic element 142 may be fixed in various ways.

The elastic element 142 may close the powder passage 130 by elastically pressing the stopper 140 in the direction of closing the powder passage 130 . For example, the stopper 140 may have a cap shape that can cover one side of the powder passage 130 without any gaps.

The stopper 140 may open the powder passage 130 by moving the stopper 140 against the elastic element 142 due to a pressure change according to a user's inhalation motion through the hydrogen passage 150 .

According to the embodiment, when there is no user's suction action, the elastic element 142 presses the stopper 140 in a direction to close the powder passage 130 so that the powder passage 130 may be closed. Conversely, when a user's inhalation operation is performed, a pressure gradient is formed inside the hydrogen generating device 100, so that the stopper 140 may move in a direction to open the powder passage 130.

Specifically, with respect to the stopper 140, the pressure pushing the stopper 140 from the reaction part 110 side toward the hydrogen passage 150 side moves the stopper 140 from the hydrogen passage 150 side to the reaction part. (110) may be greater than the lateral pushing pressure. That is, as the pressure in the inner space of the hydrogen passage 150 is lower than the pressure when there is no user's inhalation, the pressure in the inner space of the reaction unit 110 becomes the pressure of the elastic element 142 and the inner space of the hydrogen passage 150. The powder passage 130 may be opened as the stopper 140 resists the elastic element 142 and moves.

When the powder passage 130 is opened, the powder 20 contained in the powder storage unit 120 is supplied to the reaction unit 110 and reacts with the reaction liquid 10 to generate hydrogen gas. The generated hydrogen gas moves in the direction of the hydrogen passage 150 when the powder passage 130 is open, and may be discharged to the outside through the hydrogen passage 150. That is, in the hydrogen generating device 100 according to the embodiment, the powder passage 130 is opened by a mechanical mechanism according to the user's inhalation operation, so that hydrogen gas is generated and discharged to the outside of the hydrogen generating device 100. there is.

According to the embodiment, the stopper 140 may include a hollow 141. One side of the hollow 141 faces at least a portion of the second protrusion 131 protruding from the inner wall of the powder passage 130 toward the center of the powder passage 130, and the other side of the hollow 141 faces the hydrogen passage 150. ) direction can be formed.

When the powder passage 130 is closed, one side of the hollow 141 is blocked by the second protrusion 131 of the powder passage 130, and as described above, the powder is powdered by the pressure change according to the user's inhalation operation. It may move in a direction of opening the passage 130 .

When the powder passage 130 is opened, both sides of the hollow 141 are opened, and hydrogen gas generated in the reaction unit 110 passes through the powder passage 130 to the hydrogen passage ( 150), the hydrogen gas may move in the direction of the hydrogen passage 150 through the hollow 141 of the stopper 140 via the powder passage 130. That is, the hollow 141 included in the stopper 140 may additionally provide a path for the hydrogen gas to move so that the hydrogen gas generated in the reaction unit 110 can more efficiently move toward the hydrogen passage 150. can

3 is a cross-sectional view showing the inside of a hydrogen generating device according to another embodiment.

Referring to FIG. 3 , the hydrogen generating device 100 according to another embodiment includes a reaction unit 110, a powder storage unit 120, a powder passage 130, a stopper 140, an elastic element 142, a hydrogen passage 150 , direct passage 152 , indirect passage 156 , auxiliary stopper 145 and auxiliary elastic element 147 . Descriptions of overlapping parts with the above drawings will be omitted below.

According to the embodiment, the hydrogen passage 150 may include a direct passage 152 directly connected to the reaction unit 110 and an indirect passage 156 connected to the reaction unit 110 via the powder storage unit 120. can Here, direct connection may mean direct connection without going through another configuration.

The direct passage 152 may be branched from at least one point of the hydrogen passage 150 and connected to the reaction unit 110 . In addition, the hydrogen generating device 100 according to the embodiment is located adjacent to at least one point of the direct passage 152, the auxiliary stopper 145 and the auxiliary stopper 145 for opening or closing the direct passage 152 It may further include an auxiliary elastic element 147 that elastically presses the direct passage 152 in a direction of closing.

The indirect passage 156 may be branched from at least one point of the hydrogen passage 150 and connected to the powder storage unit 120, and contents corresponding thereto may be the same as those described in FIG. 2 .

According to the embodiment, when there is no user's inhalation motion, the elastic element 142 presses the stopper 140 in a direction to close the powder passage 130 so that the powder passage 130 is closed, and the auxiliary elastic element 147 ) In addition, the direct passage 152 may be closed by pressing the auxiliary stopper 145 in a direction to close the direct passage 152 .

When the user's inhalation operation is performed, as the pressure in the internal space of the hydrogen passage 150 is lower than the pressure in the absence of the user's inhalation operation, the pressure in the internal space of the indirect passage 156 and the internal space of the direct passage 152 Each of the pressures may be lower than the pressure when the user does not inhale.

Accordingly, the pressure in the inner space of the reaction unit 110 becomes greater than the sum of the pressure in the elastic element 142 and the pressure in the inner space of the indirect passage 156, so that the stopper 140 resists the elastic element 142. By moving the powder passage 130 can be opened.

When the powder passage 130 is opened, the powder 20 is supplied to the reaction unit 110 , and hydrogen gas may be generated in the reaction unit 110 . Hydrogen generated in the reaction unit 110 may move toward the indirect passage 156 through the open powder passage 130 .

In addition, when the user's inhalation operation is performed, the pressure in the inner space of the reaction unit 110 becomes a greater value than the sum of the pressure of the auxiliary elastic element 147 and the pressure in the inner space of the direct passage 152, so that the auxiliary stopper 145 ) moves against the auxiliary elastic element 147, the direct passage 152 is opened, and hydrogen generated in the reaction unit 110 may move toward the open direct passage 152.

That is, as the hydrogen passage 150 includes the indirect passage 156 and the direct passage 152, an additional movement path of the generated hydrogen gas can be secured, and the user can more smoothly inhale the hydrogen.

In addition, the stopper 140 and the auxiliary stopper 145 and the elastic element 142 and the auxiliary elastic element 147 may have different physical characteristics such as shape, structure, dimension, and material. Due to the difference in physical characteristics, the displaced aspect of the stopper 140 or the auxiliary stopper 145 according to the user's suction motion may be different. The aspect of displacement may specifically mean a degree of displacement, a time point of displacement, and a displacement speed.

For example, the auxiliary elastic element 147 may have a greater modulus of elasticity than the elastic element 142 . In this case, when the user's suction operation is made, the stopper 140 is accelerated faster than the auxiliary stopper 145, and may be displaced first. Accordingly, the powder passage 130 is opened, the powder 20 is supplied to the reaction unit 110, and the auxiliary stopper 145 is displaced at approximately the time when hydrogen gas is generated, and the direct passage 152 is opened. And, the generated hydrogen gas may move toward the hydrogen passage 150 through the direct passage 152 .

That is, according to the difference in physical properties between the elastic element 142 and the auxiliary elastic element 147, the powder passage 130 and the direct passage 152 may be opened and closed differently.

4 is a cross-sectional view showing the inside of a hydrogen generating device according to another embodiment.

Referring to FIG. 4, the hydrogen generating device 100 according to another embodiment includes a reaction unit 110, a powder storage unit 120, a powder passage 130, a stopper 140, a hydrogen passage 150, a puff It may include a sensor 160 , an actuator 170 , a processor 180 and a battery 190 .

The puff sensor 160 may detect user's inhalation. The puff sensor 160 may detect a user's puff based on at least one of a flow change, a pressure change, and sound detection of an air flow introduced from the outside of the hydrogen generating device 100 . The puff sensor 160 may detect the start timing and end timing of the user's puff, and the processor 180 may determine a puff period and non-puff according to the detected start timing and end timing of the puff. ) period can be determined.

For example, the puff sensor 160 may detect a pressure change in the hydrogen generating device 100 according to the user's inhalation, but is not limited thereto.

The actuator 170 may displace or move the stopper 140 . For example, by driving the actuator 170, the stopper 140 may not only translate, but also rotate. That is, the actuator 170 may displace the stopper 140 so that the stopper 140 of various shapes can open and close the powder passage 130 regardless of the shape and structure of the stopper 140 . The actuator 170 may be, for example, a linear motor, a stepper motor, or a hydraulic and pneumatic cylinder, but is not limited thereto.

The processor 180 is electrically connected to the puff sensor 160 and the actuator 170, and controls the driving of the actuator 170 based on the user's inhalation detection of the puff sensor 160 to open the powder passage 130. can

In addition, the processor 180 may control the driving of the actuator 170 to adjust the opening time of the powder passage 130 according to the user's suction intensity detected by the puff sensor 160 . Here, the suction intensity means including suction time, suction pressure, and the like. Specifically, the processor 180 may receive a puff signal detected by the puff sensor 160 and transmit a driving command to the actuator 170 based on the received signal to control driving of the actuator 170 .

For example, the stronger the user's inhalation intensity, the more hydrogen may need to be produced. In this case, the processor 180 controls the actuator 170 to maintain the displaced state of the stopper 140 for a longer period of time so that the powder passage 130 can remain open for a longer period of time, thereby providing a relatively large amount of The powder 20 is supplied to the reaction unit 110, whereby a large amount of hydrogen gas can be produced.

Conversely, as the strength of the user's inhalation is weak, the processor 180 may generate a relatively small amount of hydrogen gas by controlling the actuator 170 so that the powder passage 130 may be open for a shorter time. there is.

Also, the processor 180 may control the output of the actuator 170 to adjust the movement speed of the stopper 140 . For example, the processor 180 may control the driving of the actuator 170 to adjust the moving speed of the stopper 140 based on the user's suction motion detected by the puff sensor 160 .

Accordingly, a time difference between when the user inhales the hydrogen generating device 100 and when the powder 20 is supplied to the reaction unit 110 to generate hydrogen can be minimized. In addition, since hydrogen gas is generated immediately after the user's inhalation operation, the user may be able to inhale the hydrogen gas more immediately.

That is, in the hydrogen generating device 100 according to the embodiment, the powder passage 130 is opened by an electrical mechanism, so that the generation of hydrogen gas is precisely controlled, and the time difference between the user's inhalation operation point and the hydrogen inhalation point is improved. can be

The battery 190 may supply power to the puff sensor 160 , the actuator 170 and the processor 180 . Battery 190 may also power other electrically operated components that may be included in hydrogen generating device 100.
