Referring to fig. 16, the electrolytic cell 2 includes a first fixing plate 21, a first insulating plate 22, an anode electrolytic plate 23, a first titanium fiber plate 24, an ionic membrane 25, a second titanium fiber plate 26, a cathode electrolytic plate 27, a second insulating plate 28 and a second fixing plate 29, which are sequentially arranged, the anode electrolytic plate 23 is provided with a water flow groove 231, the water flow groove 231 penetrates through the anode electrolytic plate 23, the water flow groove 231 is bent from bottom to top, the lower part of the water flow groove 231 is communicated with a water inlet 232, and the upper part of the water flow groove 231 is communicated with a water outlet 233; the cathode electrolytic plate 27 is provided with an air outlet 271, and the air outlet 271 is communicated with the first titanium fiber plate 24. The first fixing plate 21 and the second fixing plate 29 may be made of aluminum alloy, the first insulating plate 22 and the second insulating plate 28 may be a silica gel plate, a rubber plate or a plastic plate, the anode electrolytic plate 23 may be a titanium substrate, the cathode electrolytic plate 27 may be a general conductive metal plate, and the surface of the ionic membrane 25 may be coated or plated with a noble metal catalyst, such as a platinum catalyst. The water tank 1 is connected with the water inlet 232 and the water outlet 233 through a conduit, and the connecting position of the conduit connected with the water inlet 232 and the water tank 1 is lower than the connecting position of the conduit connected with the water outlet 233 and the water tank 1.

In operation, the cathode plate 27 is connected to the negative pole of the DC power source, and the anode plate 23 is connected to the positive pole of the DC power source. The cathode electrolytic plate 27 transfers the electric field to the second titanium fiber plate 26, the anode electrolytic plate 23 transfers the electric field to the first titanium fiber plate 24, so that a potential difference is formed between two sides of the ionic membrane 25, hydrogen ions and cations in water move directionally under the action of the potential difference, hydrogen is generated on one side of the ionic membrane 25, oxygen is generated on the other side of the ionic membrane, the generated hydrogen is transferred back to the cathode electrolytic plate 27 through the second titanium fiber plate 26, and the generated oxygen is transferred back to the anode electrolytic plate 23 through the first titanium fiber plate 24.

A water level switch and a water quality detection probe can be arranged in the water tank 1. The water level switch is connected with a water level detection circuit in the control circuit and is used for detecting the water level of the water tank 1; due to the ionic membrane, which is a component of the electrolytic cell, if too much mineral ions are in the water during the catalytic electrolysis, the pores of the ionic membrane are clogged, and the ionic membrane affects the catalytic efficiency and has a shortened life span. The water quality detection probe is connected with a water quality detection circuit in the control circuit and is used for monitoring the TDS of the water in the water injection bin in real time, and if the TDS is too large, the water injection bin stops working and an indicator lamp gives an alarm; the water quality detection probe adopts a pure titanium screw needle.

The utility model discloses a set up the bolt 3 in bank at the border of first fixed plate 21 and second fixed plate 29, exert even pressure to the multiple panel between first fixed plate 21 and the second fixed plate 29. Under the pressure, a sealed chamber is formed between the anode electrolytic plate 23 and the ionic membrane 25 and between the cathode electrolytic plate 27 and the ionic membrane 25 through the rubber sealing frame 20; arranging a first titanium fiber plate 24 and a second titanium fiber plate 26 with flat surfaces in the sealed chamber, and ensuring that the surface of the ionic membrane 25 is continuously covered by water and the generated gas can be discharged from the first titanium fiber plate 24 and the second titanium fiber plate 26 in time by utilizing the hydrophobicity and the air permeability of the first titanium fiber plate 24 and the second titanium fiber plate 26; by utilizing the conductivity of the first titanium fiber plate 24 and the second titanium fiber plate 26, a uniform electric field is formed on two sides of the ionic membrane 25, and the stable proceeding of the electrolytic reaction is ensured; by utilizing the physical characteristics of the first titanium fiber plate 24 and the second titanium fiber plate 26, such as high strength, compact inner hole and smooth and flat surface, each part of the ionic membrane 25 is clamped, so that the ionic membrane 25 is prevented from repeatedly expanding and contracting due to the periodic force in the electrolytic process, and the service life of the ionic membrane 25 is prolonged.

At the positive pole reaction end, guarantee water and ionic membrane 25 full contact, the oxygen that produces simultaneously can in time discharge, and current positive pole electrolysis board needs mill flute profile horizontal chute, because the material of positive pole electrolysis board is titanium, the cutter is worn and torn easily during titanium substrate cutting process, and the cutter cost is than higher, leads to milling flute processing cost too high, and the efficiency of production and processing is low moreover. In addition, a titanium mesh pad is arranged between the anode electrolytic plate and the first titanium fiber plate, and the four sides of the titanium mesh are uneven, so that water can flow through gaps formed on the contact surface of the titanium mesh pad and the anode electrolytic plate. Referring to fig. 18, the present invention employs a through-hole water flow groove 231, i.e. the water flow groove 231 for punching the anode electrolytic plate 23 to form a through-hole, so that water flow and air flow are both smooth and unobstructed.

Because the water flow groove 231 of the utility model is of a through hole structure, the anode electrolytic plate of the utility model can be directly processed by a metal plate punching blanking die, and has high processing efficiency and low cost. Because the anode electrolytic plate 23 does not need a blind hole water flow groove, the thickness of the anode electrolytic plate 23 can be less than or equal to 1mm, and the weight and the volume of the whole hydrogen generator are effectively reduced. Because the cost of the titanium substrate is very high, the thickness of the anode electrolytic plate 23 of the utility model is thinned to below 1mm from the existing 2mm, thereby effectively reducing the cost. The shape of the water flow groove 231 of the present invention is not limited to the curved shape, and the water flow grooves 231 of other different shapes all belong to the protection scope of the present invention.

Preferably, the anode electrolytic plate 23 of the present embodiment is provided with two sets of water flow grooves 231 which are symmetrically arranged, the two sets of water flow grooves 231 are independent from each other, water entering from the lower water inlet 232 flows in the water flow grooves 231 in two paths, and the two paths of water flow can rapidly supplement water for the first titanium fiber plate 24; in addition, the generated oxygen bubbles are collected to the water outlet 233 along with the water flow in the two water flow grooves 231 respectively and discharged, so that the continuous discharge of oxygen can be ensured, and the smoothness of the hydrogen production process is further ensured. Because the water flow groove 231 of the utility model penetrates the anode electrolytic plate 23, the generated oxygen bubbles can not be gathered too fast in the water flow groove 231 and become large bubbles, which obstruct the flow of water flow. The small bubbles in the water flow groove 231 move upwards and bring upward flowing power to water flow, so that water flow can enter from the water inlet 232 and flow out from the water outlet 233 spontaneously only by directly communicating the water inlet 232 and the water outlet 233 with the water tank 1 without arranging active power devices such as a water pump and the like.

In daily use, dust is not easy to accumulate on the top surface of the handheld part 116 higher than the plane of the handheld part, and the ridge-shaped top surface is not easy to be completely covered by sundries, so that the upper vent hole 113 arranged on the handheld part is not easy to be blocked, and the use reliability is ensured.

A gas-water separator:

referring to fig. 20, the hydrogen generated by the hydrogen generator is introduced into a gas-water separator to be subjected to gas-water separation. The gas-water separator comprises a pressure bin 4, the pressure bin 4 is a sealed box body, the top of the pressure bin is provided with a hydrogen output port 41, and the bottom of the pressure bin is provided with a hydrogen input port 42 and a water outlet 43; the hydrogen output port 42 is connected to the hydrogen outlet 5, and the water outlet 43 is connected to the water tank 1.

Specifically, the blocking pieces 44 are connected to one side wall of the pressure chamber 4, and are not connected to the other side wall, in order to increase the moving distance of hydrogen in the pressure chamber 4, two adjacent blocking pieces 44 are symmetrically arranged, that is, two adjacent blocking pieces 44 are respectively connected to the side walls on two sides of the pressure chamber 4. In order to further improve the drying effect and prevent the hydrogen from being rewetted by the water separated from the pressure chamber 4, a hydrogen input pipe 45 communicated with the hydrogen input port 42 is arranged in the pressure chamber 4, and the gas outlet of the hydrogen input pipe 45 is positioned at the upper part of the pressure chamber 4. Preferably, the top of the blocking piece 44 is provided with a notch 441, the air outlet of the hydrogen input pipe 45 is flush with the notch 441, and the hydrogen coming out from the air outlet collides with the blocking piece 44, wherein the notch 441 can increase the collision chance of the hydrogen with the blocking piece 44.

The hydrogen outlet 5 is of a microporous structure, when the overflow rate of hydrogen from the hydrogen outlet 5 is lower than the hydrogen rate of the hydrogen generator supplied to the pressure chamber 4, the pressure in the pressure chamber 4 increases, and water in the pressure chamber 4 is automatically discharged into the water tank 1. The rate of hydrogen supply from the hydrogen generator to the pressure chamber 4 is substantially constant, and the rate of hydrogen overflow from the hydrogen outlet 5 is related to the size of the hydrogen outlet 5 and the pressure chamber 4. Under the condition that the rate of hydrogen supplied to the pressure bin by the hydrogen generator is constant and the size of the pressure bin is not changed, the larger the diameter of the hydrogen outlet 5 is, the faster the hydrogen overflows from the hydrogen outlet 5, and when the discharge rate of the hydrogen is greater than the inlet rate of the hydrogen, the pressure in the pressure bin 4 cannot be increased; only if the diameter of the hydrogen outlet 5 is small enough, the discharge rate of the hydrogen can be ensured to be smaller than the inlet rate of the hydrogen; further, the hydrogen gas input port 42 has a diameter larger than that of the hydrogen gas output port 41. Preferably, the diameter of the hydrogen outlet 5 is 0.4 to 0.5 μm. If the diameter of the hydrogen outlet 5 is too small and smaller than 0.4 μm, a part of the hydrogen gas still contains a small amount of moisture, and the hydrogen outlet 5 is easily clogged with the hydrogen gas, so that the hydrogen gas cannot be discharged from the hydrogen outlet 5. The normal state is that hydrogen continues to get into pressure chamber 4, and hydrogen continues to be discharged from hydrogen outlet 5, and the pressure in pressure chamber 4 constantly increases, and when the pressure in pressure chamber 4 increases to the default, the water in pressure chamber 4 is automatic to be discharged into water tank 1 to prevent that the water in pressure chamber 4 from overflowing.

The hydrogen gas discharged from the hydrogen outlet 5 is dry and can be used as it is. When the hydrogen outlet 5 is connected with the air suction pipe, the hydrogen can be supplied to the user for suction. Referring to fig. 22, when the hydrogen port 5 is connected to the hydrogen container 6, hydrogen gas can be added to a liquid for a user to drink, wherein the liquid can be water, fruit juice, tea, milk tea, and other beverages.

When the device is shut down from a pressurized state or a normal state, the solenoid valve 46 is automatically opened, so that the pressure chamber 4 and the water tank 1 are communicated. Because the hydrogen that the hydrogen generator produced has certain temperature, the hydrogen of following hydrogen outlet 5 exhaust has same temperature, after equipment closes, because hydrogen outlet 5 is very little, the hydrogen that is located hydrogen outlet 5 cools off to condense into the drop of water and blocks up hydrogen outlet 5, the hydrogen in pressure chamber 4 also takes place to cool off simultaneously and leads to the pressure in pressure chamber 4 to be less than the pressure of water tank 1, the water in the water tank 1 flows backward and gets into pressure chamber 4, when equipment restarts, the water in pressure chamber 4 can be along with hydrogen from hydrogen outlet 5 discharges.

In order to solve the above problem, the top of the pressure chamber 4 is further provided with an air inlet 47, and the air inlet 47 is connected with a one-way valve 48. In the shutdown state, the check valve 48 and the electromagnetic valve 46 are opened, and the external air enters the pressure chamber 4 from the air input port 47 through the check valve 48, so that the pressures of the pressure chamber 4 and the water tank 1 are kept balanced, the water level in the pressure chamber 4 is ensured to be in a normal state, and when the system is restarted, the water in the pressure chamber 4 cannot be discharged along with the hydrogen.
