In order to meet the demand for hydrogen in various application scenarios, hydrogen generators have become one of the important hydrogen production devices due to their convenience and flexibility.

The top of the left electrolytic tank 3 is connected with the oxygen exhaust pipe 9, and the oxygen exhaust pipe 9 passes through the manufacturing box 1. The front and rear sides of the top of the right electrolytic tank 3 are connected with the hydrogen exhaust pipe 10. The manufacturing box 1 is provided with an electrolysis structure for electrolyzing the solution, a gas storage mechanism for storing hydrogen and a liquid adding mechanism for adding the solution.

[0030] like Figure 2 As shown, the electrolytic structure includes a battery 2, a conductive column 6, an electrolytic sheet 7 and a conductive wire 8. The battery 2 is connected to the upper part of the manufacturing box 1, and the conductive column 6 is connected to the middle of the electrolytic tank 3. The conductive wire 8 is connected between the left conductive column 6 and the positive electrode of the battery 2, and the conductive wire 8 is also connected between the right conductive column 6 and the negative electrode of the battery 2. A plurality of electrolytic sheets 7 are evenly spaced and connected to the conductive column 6.

[0031] like Figure 3 As shown, the gas storage mechanism includes an exhaust box 101, a baffle 102, an outlet pipe 103 and a valve 104. The exhaust box 101 is connected to the right side of the manufacturing box body 1. The bottom of the exhaust box 101 is connected to the hydrogen exhaust pipe 10. The upper part of the exhaust box 101 is connected to the baffle 102. The front and rear sides of the baffle 102 are connected to the outlet pipe 103. The outlet pipe 103 is located on the left side of the swing plate 11. The swing plate 11 can be opened to connect the external pipeline with the outlet pipe 103. The outlet pipe 103 is provided with a valve 104.

[0032] like Figure 2-Figure 5 As shown, the liquid adding mechanism includes a liquid storage tank 111, a liquid injection pipe 112, a water pump 113, a liquid inlet pipe 114, a columnar plug 115 and a control component. The upper part of the manufacturing box body 1 is connected to the liquid storage tank 111, and the bottom of the liquid storage tank 111 is connected to the two electrolytic tanks 3 by a liquid injection pipe 112. The bottom of the liquid storage tank 111 is installed with a water pump 113, the liquid outlet end of the water pump 113 is connected to the liquid injection pipe 112, and the liquid inlet end of the water pump 113 is connected to the inside of the liquid storage tank 111. The top of the liquid storage tank 111 is connected to the liquid inlet pipe 114, and the liquid inlet pipe 114 is plugged with a columnar plug 115.

[0033] like Figure 4 and Figure 5 As shown, the control component includes a guide sleeve 121, a floating block 122, a start button 124 and a close button 123. The guide sleeve 121 is connected to the upper part of the left electrolytic tank 3, and the guide sleeve 121 is communicated with the inside of the electrolytic tank 3. The floating block 122 is slidably connected inside the guide sleeve 121, and the close button 123 is connected to the top of the floating block 122. The start button 124 is connected to the lower part of the guide sleeve 121, and the start button 124 and the close button 123 are both electrically connected to the water pump 113.

[0034] When hydrogen production is required, the device can be used. When in use, the columnar plug 115 can be opened first, and then the solution can be injected into the liquid storage tank 111 through the liquid inlet pipe 114. At this time, since there is no solution in the electrolytic tank 3, the floating block 122 sinks and contacts the start button 124, thereby controlling the water pump 113 to operate to extract the solution in the liquid storage tank 111 and inject it into the electrolytic tank 3 through the liquid injection pipe 112, until the solution in the electrolytic tank 3 increases to contact the floating block 122. As the solution continues to increase, the floating block 122 will move upward, and the floating block 122 will move upward to drive the closing button 123 to move upward. When the closing button 123 moves upward to contact the top of the guide sleeve 121, the water pump 113 is controlled to be closed. At this time, the solution in the electrolytic tank 3 can meet the electrolysis work. Then, the solution is continued to be added to the liquid storage tank 111 until an appropriate amount of solution is added to the liquid storage tank 111, and then the columnar plug 115 is inserted into the liquid inlet pipe 114, and then the battery can be controlled. 2 discharges, and the electrolytic sheet 7 is discharged through the conductive column 6 and the conductive wire 8. The positive electrode of the left electrolytic sheet 7 discharges to electrolyze the solution into oxygen, which is discharged through the oxygen discharge pipe 9. The negative electrode of the right electrolytic sheet 7 discharges to electrolyze the solution into hydrogen, and the hydrogen can enter the exhaust box 101 through the hydrogen discharge pipe 10 and be stored in the exhaust box 101. When it is necessary to extract the hydrogen, the swing plate 11 can be opened, the pipeline can be connected to the outlet pipe 103, and then the valve 104 can be opened to discharge the hydrogen. In this way, the device can be used to produce hydrogen. In the production process, as the solution in the electrolytic tank 3 decreases, the floating block 122 will gradually sink until the floating block 122 moves to contact the start button 124, thereby starting the water pump 113 again to add the solution. After the solution is added to a certain amount, the floating block 122 floats up and contacts the close button 123 again to control the water pump 113 to close, thereby realizing the automatic replenishment of the solution.

[0035] like Figure 6 and Figure 7As shown, a cleaning mechanism is also included, which includes a driving motor 131, a driving gear 132, a transmission gear 133, an inner gear ring 134, a scraper plate 135, a connecting plate 136 and a pinion 137. A driving motor 131 is installed in the middle of the upper part of the manufacturing box 1, and the driving gear 132 is connected to the output shaft of the driving motor 131. The tops of the two electrolytic tanks 3 are both rotatably connected to the transmission gear 133, and the driving gear 132 is meshed with the transmission gear 133. The lower part of the transmission gear 133 extends into the electrolytic tank 3 and is connected to a pinion 137. The upper part of the electrolytic tank 3 is rotatably connected to an inner gear ring 134. The inner gear ring 134 meshes with the pinion 137 so that the rotation of the pinion 137 can drive the inner gear ring 134 to rotate. The left and right sides of the bottom of the inner gear ring 134 are connected to connecting plates 136. A plurality of groups of scraper plates 135 are evenly spaced and connected to the connecting plates 136. Each group of scraper plates 135 is provided with two and are sleeved on the upper and lower sides of the electrolytic sheet 7.

[0036] The driving motor 131 is controlled to operate to drive the driving gear 132 to rotate. When the driving gear 132 rotates, it can drive the transmission gear 133 to rotate. When the transmission gear 133 rotates, it can drive the pinion 137 to rotate. When the pinion 137 rotates, it can drive the inner ring 134 to rotate. When the inner ring 134 rotates, it can drive the connecting plate 136 and the scraper plate 135 to move. When the scraper plate 135 moves, it can clean the impurities on both sides of the electrolytic sheet 7, thereby achieving the effect of cleaning the electrolytic sheet 7.

[0037] like Figure 8-Figure 11 As shown, it also includes a drainage mechanism, which includes a discharge barrel 141, a liquid guide tube 142, a second valve 143, a turbine 144 and a bottom scraper 145. The middle of the bottom of the two electrolytic tanks 3 are connected with a discharge barrel 141, and the bottom of the discharge barrel 141 is connected with a liquid guide tube 142. The rear sections of the two liquid guide tubes 142 are connected to each other and the ends pass through the manufacturing box 1. The second valve 143 is provided on the liquid guide tube 142. The discharge barrel 141 is rotatably connected with a turbine 144. Three bottom scrapers 145 are evenly spaced and connected to the top of the turbine 144. The bottom scraper 145 is in contact with the bottom of the electrolytic tank 3.

[0038] After the use of the generator, when the solution needs to be discharged, the valve 2 143 can be opened, and the solution in the electrolytic tank 3 will be discharged through the discharge barrel 141 and the liquid guide tube 142. When the solution is discharged, it will impact the turbine 144, causing the turbine 144 to rotate. The rotation of the turbine 144 can drive the scraper plate 135 to rotate. When the scraper plate 135 rotates, it can clean the bottom of the electrolytic tank 3. In this way, the solution can be discharged, and the bottom of the electrolytic tank 3 can be cleaned while the solution is discharged.

[0039] like Fig.12 As shown, it also includes a partition 151 and a molecular sieve 152. Two partitions 151 are connected to the lower part of the exhaust box 101, and a molecular sieve 152 is arranged between the two partitions 151. The molecular sieve 152 can screen out the moisture mixed in the gas. When the hydrogen enters the exhaust box 101, the hydrogen will pass through the molecular sieve 152, so that the moisture in the hydrogen is screened out by the molecular sieve 152, and the hydrogen is dried to make the hydrogen purer.
