Description

Technical Field

[0001] This utility model relates to the field of electrolysis device technology, and in particular to an electrolytic cell for a hydrogen water machine and a hydrogen water machine. Background Technology

[0002] An electrolytic cell has two electrodes, a cathode and anode. Water flows through the anode and undergoes electrolysis, producing oxygen at the anode and hydrogen at the cathode. The anode of an electrolytic cell typically has an inlet and an outlet. The inlet connects to a water tank, and pure water enters the electrolytic cell from the tank through the inlet. At the anode, electrolysis produces hydrogen ions and hydroxide ions. The hydrogen ions pass through the membrane electrode between the anode and cathode to the cathode, where they gain electrons to become hydrogen atoms. These atoms then combine to form hydrogen molecules. The hydroxide ions react at the anode to produce oxygen and water. The water and oxygen from the anode return to the water tank through the outlet.

[0003] There are two water supply methods for the electrolyzer of a hydrogen water generator. One is gravity water supply, where the inlet and outlet of the electrolyzer are directly connected to a water tank, which is positioned higher than the electrolyzer. Pure water enters the electrolyzer through the inlet under gravity. The other method is water pump supply, where the pump draws pure water from the water tank and pushes it into the electrolyzer through the inlet.

[0004] Because the small electrolyzers used in hydrogen water machines (with hydrogen production typically below 100ml / min) are very small, the distance between the inlet and outlet pipes on the anode side is close, and the gravity difference between them is also small. Under gravity-fed water supply, the oxygen produced by the anode of the electrolyzer may return to the water tank through the inlet, which will affect the water intake. Over time, this can lead to a lack of water and dry burning in the anode chamber of the electrolyzer, severely shortening the lifespan of the electrolyzer. Therefore, the electrolyzers in hydrogen water machines are usually supplied with water using a water pump.

[0005] One drawback of using a water supply pump to supply water to the hydrogen water electrolyzer is that the pump emits a sound of over 40 decibels when it is running (i.e. when the electrolyzer is producing hydrogen). The sound of the pump is quite noticeable in quiet environments, which seriously affects the user experience.

[0006] To solve the above problems, this utility model proposes an electrolytic cell for a hydrogen water machine and a hydrogen water machine. Utility Model Content

[0007] The purpose of this invention is to provide an electrolytic cell and a hydrogen water machine for use in hydrogen water machines, in order to solve the problem of high noise during operation of the electrolytic cell.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An electrolytic cell for a hydrogen water machine and a hydrogen water machine are disclosed, comprising a first end plate and a second end plate. An anode plate and a cathode plate are disposed between the first end plate and the second end plate. The first end plate is provided with a first water inlet connector and a second water inlet connector. One end of the first water inlet connector is connected to the anode plate and the other end is connected to an external water tank. The first water inlet connector supplies water by gravity. One end of the second water inlet connector is connected to the anode plate and the other end is connected to the water tank via a water supply pump. The water supply pump and the water intake pump of the hydrogen water machine start and stop simultaneously.

[0010] Preferably, the vertical height of the water tank is higher than the vertical height of the electrolytic cell.

[0011] Preferably, the first water inlet connector is a flange portion that is fixedly connected to one end of the electrolytic cell. The flange portion is snapped between the first end plate and the anode plate. One end face of the flange portion abuts against the first end plate, and a sealing ring is provided between the other end face and the anode plate.

[0012] Preferably, a first partition is provided between the first end plate and the anode plate. The first end plate, the first partition, and the anode plate are respectively provided with a first through hole, a second through hole, and a third through hole that are coaxial and interconnected. The diameter of the second through hole is larger than the diameter of the first through hole and the diameter of the third through hole. The flange of the first water inlet connector is located in the second through hole.

[0013] Preferably, the first end plate is further provided with a water outlet connector, the vertical height of the water outlet connector being higher than the vertical height of the second water inlet connector being higher than the vertical height of the second water inlet connector being higher than the vertical height of the first water inlet connector being higher than the vertical height of the first water inlet connector being higher than the vertical height of the second ... second water in

[0014] Preferably, the connection structure of the second water inlet connector and the water outlet connector is the same as that of the first water inlet connector.

[0015] Preferably, the second end plate is provided with an air outlet connector, one end of which is connected to the cathode plate.

[0016] A hydrogen water machine, including the electrolyzer.

[0017] Compared with the prior art, the electrolyzer provided by this utility model is equipped with two water inlet connectors. The first water inlet connector achieves normal water supply through gravity, and the second water inlet connector supplies water through a water supply pump. The water supply pump is only started and stopped when the hydrogen water machine's water intake pump is working, which reduces the noise when only the water supply pump is used. This allows the electrolyzer of the hydrogen water machine to achieve both gravity water supply and water supply pump water supply at the same time, effectively avoiding the problem of the electrolyzer being prone to dry burning when only gravity water supply is used. At the same time, it reduces the noise problem when only the water supply pump is used (the water supply pump of the electrolyzer and the water intake pump of the hydrogen water machine start at the same time, so that the user cannot perceive the sound of the water supply pump of the electrolyzer).

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings.

[0026] It should be noted that, where there is no conflict, the embodiments and features described in this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] like Figures 1-5 As shown, an electrolytic cell for a hydrogen water machine and a hydrogen water machine include a first end plate 1 and a second end plate 2. An anode plate 3 and a cathode plate 4 are disposed between the first end plate 1 and the second end plate 2. The first end plate 1 is provided with a first water inlet connector 5 and a second water inlet connector 6. One end of the first water inlet connector 5 is connected to the anode plate 3 and the other end is connected to an external water tank. The first water inlet connector 5 supplies water by gravity. One end of the second water inlet connector 6 is connected to the anode plate 3 and the other end is connected to the water tank through a water supply pump. The water supply pump and the water intake pump of the hydrogen water machine start and stop simultaneously.

[0028] This technical solution features two water inlet connectors. When the electrolyzer is operating, the first water inlet connector 5 provides normal water supply via gravity, while the second water inlet connector 6 supplies water to the anode chamber via a water pump. The water pump only starts and stops simultaneously with the hydrogen water machine's water intake pump, reducing noise when only the water pump is used. This allows the electrolyzer of the hydrogen water machine to simultaneously achieve gravity-fed and pump-fed water supply, effectively avoiding the problem of the electrolyzer easily drying out when only gravity-fed water supply is used. It also reduces the noise problem when only the water pump is used (the electrolyzer's water pump and the hydrogen water machine's water intake pump start simultaneously, so the user cannot perceive the sound of the electrolyzer's water pump).

[0029] In one embodiment, the vertical height of the water tank is higher than that of the electrolytic cell, so that the first water inlet connector 5 can achieve gravity water supply.

[0030] In one implementation, such as Figure 3 , Figure 5 As shown, the first water inlet connector 5 is fixedly connected to one end of the electrolytic cell, which is a flange 7. The flange 7 is snapped between the first end plate and the anode plate 3. One end face of the flange 7 abuts against the first end plate, and a sealing ring 8 is provided between the other end face and the anode plate 3.

[0031] like Figure 3 As shown, a first partition 9 is provided between the first end plate 1 and the anode plate 3. The first end plate 1, the first partition 9, and the anode plate 3 are respectively provided with a first through hole 10, a second through hole 11, and a third through hole 12 that are coaxial and interconnected. The diameter of the second through hole 11 is larger than the diameter of the first through hole 10 and the diameter of the third through hole 12. The flange 7 of the first water inlet connector 5 is provided inside the second through hole 11. Further, the outer diameter of the flange 7 is larger than the diameter of the first through hole 10 and the third through hole 12, and the inner diameter of the water inlet connector 5 can be equal to the diameter of the third through hole 12.

[0032] The anode inlet and outlet water connectors 13 of the electrolyzer used in existing hydrogen water machines typically use threaded quick-connect connectors. These connectors are screwed onto the anode plate 3 of the electrolyzer via threads. When the screwing force is too large, the connector is prone to breakage; when the screwing force is too small, it can affect the sealing performance and easily lead to water leakage problems.

[0033] The connector connection method adopted in this utility model uses the flange 7 for snap-fit, which avoids the easy breakage or water leakage of the threaded quick-connect connectors commonly used in electrolytic cells.

[0034] In one embodiment, the first end plate 1 is further provided with a water outlet connector 13. The vertical height of the water outlet connector 13 is higher than the vertical height of the second water inlet connector 6. The vertical height of the second water inlet connector 6 is higher than the vertical height of the first water inlet connector 5. The second water inlet connector 6 is located between the water outlet connector 13 and the first water inlet connector 5, making gravity water supply more reliable. When the electrolytic cell is installed, the first water inlet connector 5 is located on the lower side, and the second water inlet connector 6 is located on the upper side. The first water inlet connector 5, which is supplied by gravity, is set at a lower position, making the height difference between the first water inlet connector 5 and the water tank greater.

[0035] In one embodiment, the connection structures of the second water inlet connector 6 and the water outlet connector 13 are the same as those of the first water inlet connector 5. The connection structure here refers to the connection between the connector and the first end plate 1, the first partition plate 9, and the anode plate 3, all connected by a flange 7 snapping between the first end plate 1 and the anode plate 3.

[0036] In one embodiment, the second end plate 2 is provided with a gas outlet connector 14, one end of which is connected to the cathode plate 4, and the gas outlet connector 14 is used to discharge hydrogen gas.

[0037] In one embodiment, the electrolytic cell includes a first end plate 1, a first partition 9, an anode plate 3, a membrane electrode, a cathode plate 4, a second partition 15, and a second end plate 2 arranged sequentially.

[0038] A hydrogen water machine, including an electrolyzer.

[0039] It is worth noting that the pump supplying water to the hydrogen water machine is the intake pump, and the pump supplying water to the electrolyzer is the supply pump. Both the intake pump and the supply pump are commonly used equipment, and will not be described in detail here. The simultaneous start-up and shutdown of the supply pump and the intake pump can also be achieved through existing control methods, which are existing technologies.
