The water for linking the outside of housing 11 and water pot 30 is connected with the top of water pot 30 and supplies road 31.Water pot 30 and water The connecting portion on road 31 is supplied as the gas in water pot 30 to be played to the outside gas discharge port 30h released of device Function.That is, water supply road 31 releases road to play function as the gas for gas to be released.It should be noted that also may be used To set other gas discharge port (gas releasing road) for water supplies road 31.Level sensor is configured with water pot 30 Device 61.The situation that the water W in water pot 30 reaches lower limit water level WL is detected by level sensor 61.As shown in figure 1, water can also be made A part of 30a of tank 30, which attenuates and utilizes stream that a part of 30a is decomposed into monomer 20 with electricity, to be connected.

One end (first end 41a) of first flow path 41 is connected with the bottom of cathode chamber 21.The other end of first flow path 41 (the second end 41b) is connected with pipe 50.At least a portion of first flow path 41 and at least a portion of housing 11 can also be made To be transparent, in from the external visual of device 100 to first flow path 41.By in this way, can visually confirm The bubble of the hydrogen moved in first flow path 41.As shown in figure 1, a part of 41c of first flow path 41 can also be made thicker and saturating It is bright.Also, it can also be formed to from the external visual of device 100 a part of 41c.

Second flow path 42 is connected to both in a manner of the bottom of anode chamber 22 and water pot 30 to be linked.3rd stream 43 with The mode that the top of anode chamber 22 and water pot 30 link is connected to both.30 pairs of water pot (the first groove) is to anode (anode chamber 22) The waterborne liquid of supply is kept.

The one of the end 41b in the downstream of first flow path 41 and the upstream side of hydrogen gas flow path 44 is connected with the upper end of pipe 50 Hold (first end 44a).In their bound fraction, they can be configured to Y shape as shown in Figure 1.In pipe 50 extremely Few bottom is configured in water pot 30.The opening portion 50a of the lower section of pipe 50 is configured at the position than lower limit water level WL on the lower, as The outlet of hydrogen when the stream of hydrogen is cut off and play function.Opening portion 50a is configured to make to release from opening portion 50a Hydrogen can reach gas discharge port 30h.That is, the flowing of hydrogen of the hydrogen discharging gear release mechanism (pipe 50) in hydrogen gas flow path is pressed down When processed, hydrogen is set to flow into groove (water pot 30), so that hydrogen reaches gas discharge port 30h.

The other end (the second end 44b) of hydrogen gas flow path 44 is connected to connector 45.Connector 45 is can to connect hydrogen The connector of stream 201.Hydrogen gas flow path 201 is inserted in container 200.Container 200 has lid 200a, limitation inner space and outside Gas movement.Also hydrogen gas flow path 202 can also be connected with lid 200a.

When the electricity for entering water-filling decomposes, first, supply road 31 from water and supply water (deionized water) to water pot 30.Supply to water The water W of tank 30 is supplied to anode chamber 22 via stream 42 and stream 43.Then, monomer 20 is decomposed to electricity by dc source 12 Two electrodes between apply DC voltage, electric decomposition is carried out to water.Decomposed by the electricity to generate hydrogen in negative electrode, in Anode Into oxygen.Flowed to water pot 30 by the 3rd stream 43 in the oxygen that anode chamber 22 generates, and further released by gas Mouth 30h and water supply road 31 and released to the outside of device.When oxygen is by three streams 43, the water in anode chamber 22 Flowed to the side of water pot 30.As a result, produce the flowing of the water circulated between water pot 30 and anode chamber 22.Can also in order that The water capacity easily flows from water pot 30 to anode chamber 22, and makes the stream 43 of second flow path 42 to the three thick.Generally, device is configured to： Make to flow to hydrogen gas flow path 44 by opening portion 50a from the oxygen that stream 43 is released.Such as can not stream 43 with The surface configuration opening portion 50a of the connecting portion of water pot 30.

In the hydrogen that cathode chamber 21 generates by first flow path 41 and to the upper flow of pipe 50.Supply to anode chamber 22 A part for water is flowed by membrane-electrode assembly 23 to cathode chamber 21.In preferable one, the water of cathode chamber 21 is flow to Flowed with the movement of hydrogen in first flow path 41, reach pipe 50.Such as by making first flow path 41 attenuate, water can be made Moved with together with hydrogen.

The water for reaching pipe 50 falls at pipe 50 and returns to water pot 30.As a result, the hydrogen in the downstream of first flow path 41 Air-flow road 44, substantially only stream has hydrogen.So, pipe 50 plays function as water collector.Herein, it is necessary to no matter water pot 30 How is interior water level, water is not flowed to hydrogen gas flow path 44.Therefore, generally, the high position of peak level in than water pot 30 Put and be connected hydrogen gas flow path 44 with pipe 50.It should be noted that in order to easily be used as water collector to play function, can also make The entirety of pipe 50 is thicker, or makes the part of connection first flow path 41 thicker.

The hydrogen for flowing to hydrogen gas flow path 44 is blown into the liquid 210 in container 200 by hydrogen gas flow path 201.Liquid 210 be, for example, the liquid (water etc.) drunk.The high liquid of hydrogen concentration (such as hydrogen can be deposited as molten by being blown into the liquid of hydrogen Water) utilize.The undissolved hydrogen in liquid 210 is by hydrogen gas flow path 202 and to the flows outside of container 200.The hydrogen can Used as inhalant hydrogen.In this case, inhalant utensil can also be connected with the end of hydrogen gas flow path 202 (such as nose conduit etc.).

Before the generation of beginning hydrogen (before the internal pressure in pipe 50 rises), the water level (position on the surface of water in pipe 50 Put) it is identical with the water level in water pot 30.That is, in pipe 50 30 from opening portion 50a to water pot in the water surface position untill by water It is full of.On the other hand, when generating hydrogen, as shown in figure 1, the water level in pipe 50 reduces and water level and hydrogen in container 200 The difference of height L1 identical amounts of the front end (open end) on air-flow road 201.It should be noted that in order to be readily appreciated that, in Fig. 1, The hacures different from the hacures of the water W in water pot 30 are noted to the water gauge in pipe 50.In addition, on water and electricity in stream The water in monomer 20 is decomposed, omits hacures.

Generally, lower limit water level WL is set as follows：Make between lower limit water level WL and opening portion (gas discharge outlet) 50a Difference of height L2 containers 200 in water level and hydrogen gas flow path 201 open end between difference of height L1 maximum it is big.At this In the case of, in usual driving, the water level in pipe 50 is positioned at the position than opening portion 50a by the top.In order to as far as possible by opening portion 50a is configured at lower section, and opening portion 50a can also be configured to the thin part (such as a part of 30a) of water pot 30.But, it is excellent Choosing makes not flow to second flow path 42 from the hydrogen that opening portion 50a is released.

It should be noted that the water level that can also be detected in level sensor 61 in water pot 30 reaches lower limit water level WL When, stop the electricity decomposition of water.Alternatively, it is also possible to which opening portion 50a is arranged at into following location, the position is such that in water pot 30 Water level when reaching lower limit water level WL, the bubble of hydrogen will not be released from the front end of hydrogen gas flow path 201 because of the relation of pressure Position.In this case, level sensor 61 can be omitted.In any case, the water level in water pot 30 is caused to reach During lower limit water level WL, the bubble of hydrogen is not released from the front end of hydrogen gas flow path 201.Therefore, user can be by hydrogen from hydrogen The presence or absence of releasing of front end of stream 201 is used as the benchmark of the supply of water.

Here, the situation that research hydrogen gas flow path 201 has unexpectedly been bent by certain reason.In this case, hydrogen stream The flowing of hydrogen in road 201 is exceedingly suppressed (cut-out).On the other hand, the situation of hydrogen is continuously generated in cathode chamber 21 Under, the internal pressure rise of first flow path 41 and downstream (pipe 50 and hydrogen gas flow path 44).As a result, the water level decreasing in pipe 50 Untill the opening portion 50a for reaching pipe 50.Also, the hydrogen generated is expelled in water pot 30 from opening portion 50a.Discharged Hydrogen supplies road 31 to be discarded to the outside of device by gas discharge port 30h and water.As described above, pipe 50 is used as hydrogen Discharging gear release mechanism and play function.That is, hydrogen is made to release round when the flowing of hydrogen of the pipe 50 in hydrogen gas flow path is suppressed.It is logical Hydrogen discharging gear release mechanism as use is crossed, so that when hydrogen gas flow path is cut off, just can be simply without electric control Hydrogen is discarded to outside device.

Device of the present utility model can also possess inadequately to be suppressed for the flowing to the gas in hydrogen gas flow path The sensor that the situation of (such as cut-out) is detected.Also, it can also detect that hydrogen gas flow path is inadequately inhibited In the case of, stop the electricity decomposition of water.Such as the situation for being used to reach the water level in pipe 50 assigned position can be used to carry out The sensor of detection.When the flowing of hydrogen is cut off in hydrogen gas flow path, the water level in pipe 50 is greatly reduced.In addition, in oxygen Releasing path (such as water supply road 31) when being cut off, the water level in pipe 50 is substantially increased.By detecting this by sensor The situation of sample and stop electric decomposition, can prevent it not being situation that electric decomposition is persistently carried out in the state of usual driving.Pass through In the lump using such sensor and above-mentioned hydrogen discharging gear release mechanism, so as to not play the feelings of function well even in sensor , also can be by hydrogen to simply releasing outside device under condition.It should be noted that as sensor, can also be in pipe 50 Switch is configured to control the flowing of gas, liquid.

In device of the present utility model, in order to easily supply water to water pot, can also be set to can be by containers such as PET bottles Directly it is linked to water pot.In this case, it is different from the structure shown in Fig. 1, preferably it is separately provided gas discharge port.In Fig. 2A Illustrate the ability to the containers such as PET bottle being directly linked to one of the structure of the situation of water pot in~Fig. 2 C.It should be noted that In Fig. 2A~Fig. 2 C, involved part is only illustrated.

In Fig. 2A device, the water in container 70 is supplied to water pot 30.In this case, water pot 30, which has, is used to connect Connect the carrier 33 of container 70.In addition, connecting gas in water pot 30 releases road 32, the gas is released road 32 and is used in water pot Gas is released to the outside of device.Gas, which releases road 32 and the connecting portion of water pot 30, turns into gas discharge port 30h.

Carrier 33 has the shape of the connecting portion 71 for holding container 70.Carrier 33 includes pin 33a, to pin 33a The plate 33b and the adapting table 33c of undertaking connecting portion 71 supported.Formed with the insertion for running water through on plate 33b Hole.Connecting portion 71 includes cylindrical portion 71a, the float 71b and bulbous member 71c of the ring-type being configured in cylindrical portion 71a.It is spherical Component 71c plays function as valve.

When the container 70 for being put into water is arranged at into carrier 33 under the hydropenic state in water pot 30, such as Fig. 2 B Shown, float 71b and bulbous member 71c decline, and cylindrical portion 71a is not blocked.Therefore, supplied from cylindrical portion 71a to water pot 30 Feedwater.When the water level of water pot 30 rises with the supply of water, as shown in Figure 2 C, float 71b rises and bulbous member 71c Therefore rise.As a result, cylindrical portion 71a is blocked by bulbous member 71c, the supply of water stops.Therefore, the water in water pot 30 At the time of W reaches predetermined water level, the supply of the water from container 70 can be automatically stopped.Moreover, when the water of water pot 30 is reduced to During lower than predetermined water level position, float 71b declines and supplies water.In such manner, it is possible to automatically the water level of water pot 30 is remained It is fixed.It should be noted that the structure shown in Fig. 2A is one, electricity can be played and the knot shown in Fig. 2A by other structures The same function of structure.
