Description

Technical Field

[0001] The present application relates to the technical field of water tanks, and in particular to a pure water recovery water tank for a hydrogen generator. Background Art

[0002] Currently, more and more people adopt the maintenance methods of inhaling hydrogen or drinking hydrogen water for the purpose of health preservation and anti-aging. Some studies have pointed out that hydrogen can scavenge free radicals in the body and achieve the effect of antioxidant. However, the equipment for producing hydrogen is bulky and inconvenient to use.

[0003] In the related art, the principle of hydrogen production is that the electrolytic cell electrolyzes pure water to produce hydrogen and oxygen. The hydrogen produced by electrolysis is saturated with water vapor and has a too high temperature. If the electrolyzed hydrogen is directly used, it may cause burns or choking of the user by water vapor. Therefore, in addition to setting a water tank to supply water to the electrolytic cell, the hydrogen generator also sets another water tank to recover the water after filtering the excess water vapor in the hydrogen.

[0004] Regarding the above related art, the inventor believes that setting two water tanks must occupy too much volume, and the water tank needs to be replenished continuously, which is not convenient to use. Summary of the Invention

[0005] In order to improve the problem that setting two water tanks must occupy too much volume and the water tank needs to be replenished continuously, the present application provides a pure water recovery water tank for a hydrogen generator.

[0006] A pure water recovery water tank for a hydrogen generator provided by the present application adopts the following technical solutions:

[0007] A pure water recovery water tank for a hydrogen generator includes an outer water tank, on which a hydrogen inlet, a hydrogen outlet, an oxygen inlet and an oxygen-dispersing hole are formed; and a first tubular part, a second tubular part and a third tubular part are arranged on the outer water tank; the first tubular part includes a first end and a second end, the first end is connected to the hydrogen inlet, and the second end communicates with the hydrogen outlet; the second tubular part is sleeved outside the first tubular part and communicates with the second end of the first tubular part, and the second tubular part includes a first communication hole; the third tubular part is arranged inside the outer water tank and sleeved outside the second tubular part, and the third tubular part includes a second communication hole, wherein the first communication hole and the second communication hole communicate the outer water tank, the third tubular part and the second tubular part with each other.

[0008] Optionally, the hydrogen inlet, the first communication hole and the second communication hole have the same size.

[0009] Optionally, the apertures of the hydrogen inlet, the first communication hole, and the second communication hole are from 0.3 mm to 0.5 mm.

[0010] Optionally, the first communication hole is located at the bottom of the second tubular part.

[0011] Optionally, the second communication hole is located at the bottom of the third tubular part.

[0012] Optionally, the bottom of the outer water tank includes a convex part, the convex part includes a bottom surface, a middle column, and a top convexity. The middle column extends upward from the bottom surface, and the top convexity extends upward from the middle column. The hydrogen inlet is located on the top surface of the top convexity. The second tubular part is sleeved on the top convexity, and the third tubular part is sleeved on the middle column.

[0013] Optionally, the first communication hole is formed between the top convexity and the second tubular part.

[0014] Optionally, the first communication hole is formed by a first groove, and the first groove extends from the top surface of the top convexity to the top surface of the middle column.

[0015] Optionally, the second communication hole is formed between the bottom surface and the third tubular part.

[0016] Optionally, the second communication hole is formed by a second groove, and the second groove extends from the top surface of the middle column to the bottom surface.

[0017] In summary, the present application includes at least one of the following beneficial technical effects for the pure water recovery water tank of the hydrogen generator:

[0018] In operation, connect the first end of the first tubular part to the hydrogen inlet, and the second end communicates with the hydrogen outlet. Then, sleeve the second tubular part outside the first tubular part and connect it to the second end of the first tubular part. After that, sleeve the third tubular part outside the second tubular part. The first communication hole and the second communication hole connect the outer water tank, the third tubular part, and the second tubular part to each other. The hydrogen saturated with water vapor produced by the electrolytic cell enters the first end of the first tubular part from the hydrogen inlet, rises to the second end, and then leaves from the hydrogen outlet. The rising hydrogen bubbles will pass through the water in the first tubular part to cool the hydrogen and condense the excess water vapor. Through the buffering effect between the first tubular part, the second tubular part, and the third tubular part, balanced water supply can be achieved, without obstructing the gas outlet or water outlet. Thus, the need for setting up redundant water tanks is eliminated, the excessive volume occupied by the redundant water tanks is reduced, enabling the water tank to supply water simultaneously and recover the excess water in the hydrogen. The water tank has a small volume and can provide electrolytic water for a long time without the need for continuous water replenishment. Description of the Drawings

Detailed implementation manners

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0027] Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art to which the present application belongs. The words such as "one" or "a" used in the description and claims of the present patent application do not denote a limitation of quantity, but rather denote the presence of at least one.

[0028] The following will further describe the present application in detail with reference to the attached Figures 1-6 drawings.

[0029] The embodiments of the present application disclose a pure water recovery water tank for a hydrogen generator.

[0030] Refer to Figure 1, A pure water recovery water tank for a hydrogen generator, comprising an outer water tank 1, a first tubular part 20, a second tubular part 30, and a third tubular part 40. Among them, the diameter of the first tubular part 20 is smaller than that of the second tubular part 30, and the diameter of the second tubular part 30 is smaller than that of the third tubular part 40. The outer water tank 1 includes a hydrogen inlet 11, a hydrogen outlet 12, an oxygen inlet 13, an oxygen-dispersing hole 14, and a water intake hole 15. The water intake hole 15 is used to provide water required by the electrolytic cell, and the electrolytic cell electrolyzes water to produce hydrogen and oxygen. The hydrogen and oxygen just after electrolysis are not only at a high temperature but also saturated with water vapor. If directly supplied for the user to inhale, it may cause burns or choking. Therefore, the produced hydrogen and oxygen will return to the inside of the outer water tank 1 through the hydrogen inlet 11 and the oxygen inlet 13, so that the high-temperature hydrogen and oxygen can be cooled by the water in the outer water tank 1 and the excess water vapor can be condensed out.

[0031] The outer water tank 11 is provided to match the shape of the hydrogen generator, and the outer water tank 1 is generally rectangular parallelepiped-shaped, and the length direction of the outer water tank 1 is vertically arranged. The first tubular part 20, the second tubular part 30, and the third tubular part 40 are long circular tubes. The diameters among the first tubular part 20, the second tubular part 30, and the third tubular part 40 are in turn that the first tubular part 20 is smaller than the second tubular part 30, and the second tubular part 30 is smaller than the third tubular part 40. The inner diameter of the first tubular part 20 is the smallest and thinnest, the inner diameter of the third tubular part 40 is the largest and thickest, and the inner diameter of the second tubular part 30 is between the inner diameters of the first tubular part 20 and the third tubular part 40. During use, the first tubular part 20, the second tubular part 30, and the third tubular part 40 are sleeved with each other and connected to the inner bottom layer of the outer water tank 1, so as to be fixed inside the outer water tank 1 and will not collide with the inner wall of the outer water tank 1. Since the gas passes between the first tubular part 20, the second tubular part 30, and the third tubular part 40, the first tubular part 20, the second tubular part 30, and the third tubular part 40 will have slight vibrations. If the first tubular part 20, the second tubular part 30, and the third tubular part 40 are not fixed, leakage will occur between the first tubular part 20, the second tubular part 30, and the third tubular part 40, affecting the recovery of pure water. Therefore, the working stability among the first tubular part 20, the second tubular part 30, and the third tubular part 40 is improved.

[0032] Reference Figure 2 And 3, a hydrogen inlet 11 is provided at the bottom of the outer water tank 1, and two ends of the first tubular part 20 are respectively connected to the hydrogen inlet 11 and the hydrogen outlet 12. The outer water tank 1 further includes a water tank cover 16 which covers the outer water tank 1, and both the hydrogen outlet 12 and the oxygen-dispersing holes 14 are provided on the water tank cover 16. The second tubular part 30 is sleeved outside the first tubular part 20, and the second tubular part 30 and the first tubular part 20 communicate with each other. In some embodiments, the second tubular part 30 and the first tubular part 20 communicate with each other through holes. In other embodiments, the second tubular part 30 and the first tubular part 20 communicate with each other near the hydrogen outlet 12, the hydrogen is cooled and the excess water vapor is condensed on the inner tube wall of the first tubular part 20 or the tube wall between the second tubular part 30 and the first tubular part 20. So that the efficiency of condensing water vapor on the first tubular part 20 and the second tubular part 30 is improved, and the condensed liquid water can be well recycled and utilized.

[0033] Since the cooling of hydrogen will condense the excess water vapor on the inner tube walls of the first tubular part 20 and the second tubular part 30, if metal fixing parts such as screws are used, the metal fixing parts will rust, resulting in some metal impurities in the hydrogen generated by the hydrogen generator, which affects the safety of people inhaling hydrogen. After improvement by the designer, the inner diameter of the upper end of the second tubular part 30 is smaller than the inner diameter of the first tubular part 20, and the first tubular part 20 is connected to the hydrogen outlet 12 through the upper end of the second tubular part 30. In other words, the first tubular part 20 is connected to the hydrogen outlet 12 through the second tubular part 30 and the third tubular part 40. In this way, the first tubular part 20, the second tubular part 3 and the third tubular part 40 are fixed to each other at the end connected to the hydrogen outlet 12, and no additional fixing parts are needed. On the one hand, the safety of people inhaling hydrogen is improved, and on the other hand, the service life of the water tank of the hydrogen generator is extended.

[0034] In one embodiment, the inner diameter of the second tubular part 30 is slightly larger than that of the first tubular part 20, and the inner diameter of the third tubular part 40 is 3 times that of the second tubular part 30. And the lengths of the first tubular part 20, the second tubular part 30 and the third tubular part 40 are about 2 / 3 of the height of the outer water tank 1. Among them, the length of the third tubular part 40 is greater than that of the first tubular part 20, the first tubular part 20 is greater than the second tubular part 30, and the second tubular part 30 is the shortest.

[0035] Reference Figure 3 , the second tubular part 30 and the third tubular part 40 are tapered in a stepped manner at the end connected to the hydrogen outlet 12, so as to improve the connection stability between the first tubular part 20, the second tubular part 30 and the third tubular part 40.

[0036] Figure 4 This is a partial cross-sectional view of the hydrogen generator mainly shown in this embodiment. Figure 4 Compared withFigure 2 They are cross-sectional views in two different directions, Figure 2 and Figure 4 is a cross-sectional view of the hydrogen generator. Figure 5 is a partially enlarged view of the outer water tank 1 mainly embodied in this embodiment. The second tubular part 30 further includes a first communication hole 31. The third tubular part 40 is disposed inside the outer water tank 1 and sleeved outside the second tubular part 30. The third tubular part 40 includes a second communication hole 41. The first communication hole 31 and the second communication hole 41 communicate the outer water tank 1, the third tubular part 40 and the second tubular part 30 with each other. Thereby, the hydrogen entering from the hydrogen inlet 11 at the lower end of the first tubular part 20 rises to the upper end and then leaves from the hydrogen outlet 12, and the rising hydrogen bubbles will pass through the water in the first tubular part 20. When there is too much water in the first tubular part 20, it will escape from the part communicating with the second tubular part 30 at the upper end to the second tubular part 30, and the third tubular part 40 and the second tubular part 30 communicate with each other.

[0037] Since the hydrogen inlet 11, the first communication hole 31 and the second communication hole 41 have the same size, the water between the outer water tank 1, the second tubular part 30 and the third tubular part 40 reaches balance, enabling the water to be recycled and ensuring unobstructed water flow. It reduces the occurrence of blockage in the water tank during the use of the hydrogen generator and improves the convenience of using the hydrogen generator.

[0038] The apertures of the hydrogen inlet 11, the first communication hole 31 and the second communication hole 41 of the water tank are 0.3 mm to 0.5 mm. Preferably, the apertures of the hydrogen inlet 11, the first communication hole 31 and the second communication hole 41 of the water tank are 0.4 mm, so that the water in the water tank can reach balance when the electrolytic cell consumes 5 cc / hr of water.

[0039] In this embodiment, the second communication hole 41 is located at the bottom of the third tubular part 40. In some embodiments, the first communication hole 31 and the second communication hole 41 are located on the wall surfaces of the second tubular part 30 and the third tubular part 40 close to the bottom to ensure that the communication holes are below the water level.

[0040] In one embodiment, the bottom surface 170 of the outer water tank 1 is provided with grooves. When the second tubular part 30 and the third tubular part 40 are sleeved on the bottom surface 170 of the outer water tank 1, the first communication hole 31 and the second communication hole 41 are formed by the grooves. Forming the communication holes through the grooves can make the manufacturing process simpler and improve the reliability of the finished product.

[0041] Reference Figure 4 and 5, the bottom of the outer water tank 1 includes a convex portion 17, which extends upward in a stepped manner from the bottom of the outer water tank 1, and the central position of the convex portion 17 is higher than the surrounding. The convex portion 17 includes a bottom surface 170, a middle column 172, and a top convex 174. The bottom surface 170 is a square surface, the middle column 172 is cylindrical and extends upward from the bottom surface 170, and the top convex 174 is also cylindrical and extends upward from the middle column 172. The hydrogen inlet 11 is located on the top surface of the top convex 174. The second tubular portion 30 is sleeved on the top convex 174, and the third tubular portion 40 is sleeved on the middle column 172.

[0042] In some embodiments, the first communication hole 31 is formed between the top convex 174 and the second tubular portion. In one embodiment, the first communication hole 31 is formed by the first groove 171, and the first groove 171 extends from the top surface of the top convex 174 to the top surface of the middle column 172. Continue to refer to Figure 3 , when the bottom end of the second tubular portion 30 is sleeved on the top convex 174, the inner wall surface of the second tubular portion 30 is closely joined to the outer surface of the top convex 174. Therefore, the inside of the second tubular portion 30 is communicated with the inside of the third tubular portion 40 through the first groove 171.

[0043] Continue to refer to Figure 5 , in one embodiment, the second communication hole 41 is formed between the bottom surface 170 and the third tubular portion 40. In one embodiment, the second communication hole 41 is formed by the second groove 173, and the second groove 173 extends from the top surface of the middle column 172 to the bottom surface 170. In one embodiment, the first groove 171 and the second groove 173 communicate with each other. Continue to refer to Figure 3 , when the bottom end of the third tubular portion 40 is sleeved on the middle column 172, the inner wall surface of the third tubular portion 40 is closely joined to the outer surface of the middle column 172. Therefore, the inside of the third tubular portion 40 is communicated with the inside of the outer water tank 1 through the second groove 173.

[0044] Figure 6 This is a schematic diagram mainly showing the appearance of the hydrogen generator in this embodiment. By sleeving the first tubular portion 20, the second tubular portion 30, and the third tubular portion 40 inside the outer water tank 1, the water tank saves more space. Therefore, the hydrogen generator using the water tank of this application can have a more miniature and beautiful appearance. The hydrogen generator further includes a condensing pipe 60, which is connected to the hydrogen outlet 12, preventing the temperature difference between the hydrogen and the outside air from being too large to generate more water vapor, and retaining the generated water in the condensing pipe 60 to avoid the water being discharged along with the hydrogen. Silica gel balls are arranged in the condensing pipe 60 to prevent the water from flowing back to the hydrogen outlet 12. A one-way valve 50 is also arranged between the condensing pipe 60 and the third tubular portion 40, which can prevent the outside air from flowing into the hydrogen generator and can further avoid the explosion of the hydrogen-oxygen mixture when encountering fire.

[0045] The implementation principle of a pure water recovery water tank for a hydrogen generator in an embodiment of this application is as follows: Before use, the water tank is fixed on the hydrogen generator. The hydrogen saturated with water vapor produced by the electrolytic cell enters the first end of the first tubular part 20 through the hydrogen inlet 11, rises to the second end, and then leaves through the hydrogen outlet 12. The rising hydrogen bubbles will pass through the water in the first tubular part 20. The hydrogen cools down and condenses the excess water vapor on the inner wall of the first tubular part 20. When the water in the first tubular part 20 is too much, it will escape to the second tubular part 30 from the part communicating with the second tubular part 30 at the upper end. When the temperature difference between the hydrogen and the outside air is too large, the condensing pipe 60 on the hydrogen outlet 12 reduces the generation of water vapor. At the same time, the generated water can be retained in the condensing pipe 60, reducing the discharge of water along with the hydrogen. The silica gel balls in the condensing pipe 60 prevent the water from flowing back to the hydrogen outlet 12, and the one-way valve 50 prevents the outside air from flowing into the hydrogen generator, preventing the occurrence of the phenomenon of hydrogen-oxygen mixture explosion when encountering fire.

[0046] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
