DETAILED DESCRIPTION

[0015] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0016] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only."

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0018] like Figure 1 As shown, a water electrolysis hydrogen and oxygen generator with automatic control function includes an inner water tank 1, the inner water tank 1 is connected to an electrolyzer 2 through a pipeline, the electrolyzer 2 is respectively provided with a first mixing pipeline 3 and a second mixing pipeline 4, the first mixing pipeline 3 is connected to a hydrogen water tank 5, the second mixing pipeline 4 is connected to an oxygen water tank 6, the hydrogen water tank 5 is connected to a hydrogen outlet nozzle 7 through a first one-way valve 9, the oxygen water tank 6 is connected to an oxygen outlet nozzle 8 through a second one-way valve 10, and the hydrogen water tank 5 and the oxygen water tank 6 are connected to the inner water tank 1 through a pipeline. At this time, the electrolysis of water is used to realize automatic hydrogen production, and then the oxygen and hydrogen obtained by electrolysis are discharged from the oxygen outlet nozzle 8 and the hydrogen outlet nozzle 7 respectively, so as to realize the production of hydrogen and oxygen by electrolysis of water.

[0019] Since the inner water tank 1 is arranged inside the electrolytic water hydrogen and oxygen generator, in order to avoid the trouble of adding water during use, in this embodiment, the electrolytic water hydrogen and oxygen generator further comprises an outer water tank 11, which is connected to the inner water tank 1 through a pipeline, and the outer water tank 11 is provided with an air inlet. The inner water tank 1 is connected through the outer water tank 11 to replenish water to the inner water tank 1, and the outer water tank 11 is arranged outside the electrolytic water hydrogen and oxygen generator, so it is more convenient to add water. At the same time, during the use of the outer water tank 11, pure water sold on the market can be added, which is more convenient.

[0020] In order to allow the water in the outer water tank 11 to flow into the inner water tank 1, a water pump 12 is provided in the pipeline between the outer water tank 11 and the inner water tank 1 to provide water flow power. At the same time, a filter 13 is also provided in the pipeline to filter impurities to avoid the presence of certain impurities in the oxygen generated by electrolysis, thereby improving safety during use.

[0021] Of course, when the outer water tank 11 is used to supply water to the inner water tank 1, it is necessary to understand the water level in the inner water tank 1. Therefore, in the present embodiment, the inner water tank 1 is provided with a water level detection structure 15. At this time, the water level detection structure 15 uses a water level sensor for detecting the liquid height in the inner water tank 1. Furthermore, the inner water tank 1 is also provided with a water shortage detection structure. The so-called water shortage detection structure uses a water level sensor to detect the height position of the liquid in the inner water tank 1, and judges the actual liquid height by the preset low liquid level height position. If the actual liquid height is equal to the low liquid level height, the water pump 12 is started, and the outer water tank 11 supplies water toward the inner water tank 1, so that the liquid in the inner water tank 1 increases to the preset high liquid level height position, and then the water pump 12 is turned off, thereby realizing the liquid height control in the inner water tank 1. At this time, the circuits involved adopt the existing technical solutions, so they are not described in detail here.

[0022] Since the electrolyzer 2 generates hydrogen during the electrolysis process, and hydrogen can be directly discharged into the external environment, and excessive hydrogen in the environment can cause explosion, it is necessary to strictly check the hydrogen content in the air. In this embodiment, the electrolytic water hydrogen and oxygen generator also includes a hydrogen detection structure 14, which is arranged outside the electrolytic water hydrogen generator to detect the hydrogen content in the air. Specifically, in this embodiment, a hydrogen detector (such as the NGP5-50 fixed all-in-one gas detector produced by Ningbo Gaopin Technology Co., Ltd.) is used. When the hydrogen content in the air is detected to be high, an alarm can be issued, and the data will be transmitted to the electrolytic water hydrogen and oxygen generator, thereby terminating the continued electrolysis of the electrolytic cell 2 to avoid accidents.

[0023] Since the water in the electrolytic cell 2 needs to be kept within a certain temperature range during the electrolysis process to achieve the highest electrolysis efficiency, in this embodiment, the electrolytic cell 2 is provided with a temperature detection structure 16, such as a temperature sensor, for detecting the water temperature in the electrolytic cell 2. When the water temperature is too high, the electrolysis is stopped. At the same time, a fan is provided on the outside of the electrolytic cell 2. When the water temperature in the electrolytic cell 2 is too high, the fan continues to work for cooling.

[0024] In order to further ensure that the electrolyzed water is in a pure water state, in this embodiment, the pipe connecting the inner water tank 1 and the electrolytic cell 2 is provided with a water quality detection structure 17. At this time, the water quality detection structure 17 adopts a water quality detector. Of course, considering the convenience of installation of the water quality detector, the water quality detector can also be set in the inner water tank 1, so as to detect the water quality at the position of the inner water tank 1, so as to ensure that the oxygen generated by electrolysis can be inhaled.

[0025] Oxygen produced by electrolysis in the electrolyzer 2 will contain some water, so an oxygen water tank 6 is provided to further separate oxygen from water. In order to make the product volume smaller, in this embodiment, the oxygen water tank 6 is an inner water tank 1, and the second mixing pipe 4 connects the electrolyzer 2 and the inner water tank 1, and is used to transmit the electrolyzed oxygen to the inner water tank 1. The upper side of the inner water tank 1 is connected to the oxygen outlet 8 through the second one-way valve 10. That is, the oxygen water tank 6 is removed, and the inner water tank 1 is used as the oxygen water tank 6. The oxygen-water mixture after electrolysis is connected to the inner water tank 1 through the second mixing pipe 4, and then the oxygen and water are separated at the position of the inner water tank 1. At this time, although the concentration of oxygen will be reduced, the normal use of oxygen will be less affected.

[0026] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
