[0002] A hydrogen generator is a device that produces hydrogen. It can use fuel, catalysts and other ingredients to produce hydrogen, or it can use the electrolysis of high-purity water to produce water. The online hydrogen generator has an online monitoring function, which monitors the status of the hydrogen generator in real time and is safer.

[0003] Existing online hydrogen generators, such as the hydrogen generator proposed in patent application number "CN202322399190.6", generate hydrogen by electrolyzing water in the water tank through structures such as a support block, a water tank, a control panel, an electrolysis seat, a water outlet pipe and a water inlet pipe, thereby realizing hydrogen processing and preparation.

It is necessary to observe in real time whether there is enough water in the water tank to prevent slow hydrogen production efficiency due to insufficient water, or damage to electrolytic parts due to insufficient water. Therefore, an automatic water adding device for an online hydrogen generator is proposed. Utility Model Content

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] An automatic water adding device for an online hydrogen generator, such as Figure 1-Figure 4 As shown, it includes an outer shell 1, and a water tank 2 is installed inside the outer shell 1. A fixing seat 16 is fixedly connected to the upper end of the water tank 2. A water cavity 17 is opened inside the fixing seat 16, and a water inlet 18 is opened below the inner wall of the water cavity 17. A slide 15 is slidably connected inside the fixing seat 16, and a water inlet 19 is opened at the upper end of the side wall of the slide 15. The water inlet 19 cooperates with the water inlet 18. A connecting rod 13 is fixedly connected to the middle part of the lower end of the slide 15, and a floating bag 12 is fixedly connected to the lower end of the connecting rod 13. A water injection port 14 is opened at the lower end of the slide 15.

[0024] The water tank 2, drying tube, electrolysis structure and other structures are installed inside the shell 1 by bolts. The various structures are connected to each other, and the water in the water tank 2 is electrolyzed to produce hydrogen, and the hydrogen is dried. The floating bag 12 floats on the water surface. As the water level rises and falls, when the water inside the water tank 2 is insufficient, the floating bag 12 will drop, and the connecting rod 13 will pull the slide 15 down, so that the water inlet 19 is connected with the water inlet hole 18. The water in the water cavity 17 enters the slide 15 from the water inlet hole 18 and the water inlet 19, and enters the water tank 2 through the water injection port 14. Water is added to the water tank 2, the water level increases, the height of the floating bag 12 increases, and the slide 15 slowly rises in the fixed seat 16. When water is added to a certain height, the slide 15 is lifted to a certain height, the water inlet 19 is no longer connected with the water inlet hole 18, and water addition stops. This online hydrogen generator can automatically replenish water when the water in the water tank 2 is insufficient, to prevent insufficient water in the water tank 2 from affecting the hydrogen production efficiency or damaging the electrolysis parts.

[0025] like Figure 3 As shown, the water tank 2 is slidably connected to a round frame 11, the floating bag 12 is fixed to the middle of the round frame 11, the upper end of the fixing seat 16 is fixed to a U-shaped tube 21, both ends of the U-shaped tube 21 are connected to the water cavity 17, and the middle of the U-shaped tube 21 is connected and fixed to the water inlet pipe 3.

[0026] The outer wall of the circular frame 11 is fitted and slidably connected to the inside of the water tank 2. When the water level rises and falls, the floating bag 12 drives the circular frame 11 to rise and fall. The circular frame 11 prevents the floating bag 12 from tilting, and water is added to the water cavity 17 through the water inlet pipe 3 and the U-shaped tube 21.

[0027] like Figure 2 As shown, one end of the water inlet pipe 3 away from the U-shaped tube 21 is threadedly connected to a connecting pipe 5 for connecting to an external high-purity water source, and the lower end of the side wall of the water tank 2 is connected and fixedly connected to a drain pipe 4 for discharging excess water.

[0028] The connecting pipe 5 adds water into the water cavity 17 through the water inlet pipe 3 and the U-shaped pipe 21 , and the water in the water tank 2 can be discharged through the drain pipe 4 .

[0029] like Figure 3-Figure 4 As shown, the upper end of the slide 15 is fixed with multiple groups of fixing rods 20, and the multiple groups of fixing rods 20 all pass through the top of the fixing seat 16, and the upper ends of the multiple groups of fixing rods 20 are fixed with limit blocks 22 for preventing them from falling off from the fixing seat 16. The upper end of the water tank 2 is fixed with the cover body 10, and the fixing seat 16 is located inside the cover body 10.

[0030] The fixing rod 20 prevents the slide 15 from rotating in the fixing seat 16, thereby preventing the floating bag 12 and the round frame 11 from rotating. It cooperates with the limit block 22 to prevent the slide 15 from separating from the fixing seat 16 due to the water level being too low. The cover body 10 prevents the fixing rod 20 from being exposed inside the shell 1 and causing water pollution.

[0031] like Figure 1 As shown, two groups of grooves 6 are symmetrically opened on the side wall of the housing 1 , and handles 7 are rotatably connected inside the two groups of grooves 6 , and one side of the handle 7 is in abutment with the upper wall of the groove 6 .

[0032] When the handle 7 is not in use, it is folded and stored in the groove 6. When the generator needs to be transported, the handle 7 is rotated and the hand is buckled to facilitate applying force to the shell 1 during transportation.

[0033] like Figure 1 As shown, the lower end of the housing 1 is fixedly connected to multiple groups of supporting legs 8, which are arranged in a rectangular array, and the lower ends of the multiple groups of supporting legs 8 are rotatably connected to rolling balls 9.

[0034] The multiple groups of legs 8 and balls 9 not only facilitate the free movement of the online hydrogen generator, but also support the shell 1, making it easier for the bottom of the generator to dissipate heat.

[0035] The working principle of the automatic water adding device of an online hydrogen generator provided by the utility model is as follows:

[0036] When there is insufficient water in the water tank 2, the floating bag 12 will drop, and the connecting rod 13 will pull the slide 15 down, so that the water inlet 19 is connected with the water inlet hole 18. The water in the water cavity 17 enters the slide 15 from the water inlet hole 18 and the water inlet 19, and enters the water tank 2 through the water injection port 14. Water is added to the water tank 2, the water level increases, the height of the floating bag 12 increases, and the slide 15 is slowly lifted in the fixed seat 16. When water is added to a certain height, the slide 15 is lifted to a certain height, the water inlet 19 is not connected with the water inlet hole 18, and the water adding stops. This online hydrogen generator can automatically replenish water when there is insufficient water in the water tank 2, to prevent insufficient water in the water tank 2 from affecting the hydrogen production efficiency or damaging the electrolytic parts.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
