Description

Technical Field

[0001] The utility model belongs to the technical field of direct drinking water machines, in particular to a drinking water machine. Background Art

[0002] Bubbles are classified into large bubbles, micron bubbles, submicron bubbles or nanobubbles. Some people also use more popular classifications of large bubbles, small bubbles and ultra-small bubbles. Usually, people call the diameter range of 10-100 microns as microbubbles, 1-10 microns as submicron bubbles, and 10-1000 nanometers as nanobubbles. Nanobubbles have excellent application prospects in many fields because of their large specific surface area, long residence time, high interfacial potential, free radical generation and enhanced mass transfer.

[0003] The nanobubble research team of Shanghai Advanced Research Institute / Shanghai Institute of Applied Physics, Chinese Academy of Sciences, has prepared an ultra-small particle size nanobubble that can selectively adsorb and quench ROS, thereby showing a strong antioxidant effect on the substrate. Since the gas-liquid interface of ultra-small particle size nanobubbles is non-consumable, its antioxidant effect is sustainable and its effect is cumulative. Compared with chemical reductants, ultra-small particle size nanobubbles can maintain their antioxidant capacity in a high level ROS environment, and no harmful oxidation products will remain after ROS quenching. This shows that nanobubbles have prospects in the fields of biomedicine and health. Therefore, some drinking water containing nanobubbles began to appear on the market. However, this kind of drinking water containing nanobubble water is usually prepared and packaged by factories, and people can only obtain it by purchasing.

[0004] The direct drinking water machine is a device used to provide drinking water to people. At present, the direct drinking water machines on the market can only provide conventional cold drinking water and hot drinking water. However, there is no direct drinking water machine that can produce nano bubbles on the market. Utility Model Content

[0043] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0044] Implementation Method 1

[0045] This embodiment discloses a drinking water machine, including a water tank 1 and a water outlet (not shown in the figure) connected to the water tank 1. Figure 1 As shown, the drinking water machine also includes:

[0046] A nano bubble generating component 2, used to generate nano bubbles to prepare nano bubble water, wherein the nano bubble generating component 2 has an input pipe and an output pipe;

[0047] A water filter assembly 3 connected to the water tank 1 to supply water;

[0048] The water tank 1 is connected to the input pipe to supply water to the nano bubble generating assembly 2 , and the output pipe is connected to the water tank 1 to transport nano bubble water to the water tank 1 .

[0049] The drinking water machine proposed in this embodiment generates nanobubbles through the nanobubble generating component 2 to prepare nanobubble water, and transports it to the water tank 1, and can provide nanobubble water to the outside through the water outlet connected to the water tank 1, that is, direct drinking water containing nanobubbles, filling the gap in direct drinking water machines that generate nanobubbles on the market.

[0050] In some embodiments, the nano bubble generating assembly 2 has an input pipe for inputting water, an output pipe for outputting nano bubble water, and a gas input port for inputting gas. Gas and water enter the nano bubble generating assembly 2 through the gas input port and the input pipe, respectively, and nano bubble water is prepared by the nano bubble generating assembly 2, and the prepared nano bubble water is finally output to the water tank 1 through the output pipe. Depending on the type of gas used to prepare nano bubbles, the drinking water machine in this embodiment can be used to make many types of nano bubble water, such as hydrogen nano bubble water, oxygen nano bubble water, air nano bubble water, etc.

[0051] In some embodiments, the drinking water machine can directly use air to prepare nano bubble water, that is, the gas input port of the nano bubble generating component 2 is directly connected to the atmosphere. In order to prevent impurities in the air in the atmosphere from entering the nano bubble generating component 2 and prevent the purity of the prepared nano bubble water from being affected, an air purification component can be provided at the gas input port to purify the air. In addition, in other embodiments, in order to meet the gas input pressure requirements of the nano bubble generating component 2, an air pump can also be provided at the gas input port. In other embodiments, the gas input port of the drinking water machine can be connected to a gas tank, which stores gases required for preparing nano bubbles, such as hydrogen, oxygen, etc.

[0052] It is worth mentioning that, in this embodiment, the water tank 1 is connected to the input pipe to supply water to the nano bubble generating assembly 2, and the output pipe is connected to the water tank 1 to deliver nano bubble water to the water tank 1. In other words, the water tank 1 supplies water to the nano bubble generating assembly 2 through the input pipe on the one hand, and receives the nano bubble water prepared by the nano bubble generating assembly 2 through the output pipe on the other hand, thereby forming a water circuit circulation between the water tank 1 and the nano bubble generating assembly 2. The purpose of such a setting is that, on the one hand, the water in the water tank 1 can repeatedly pass through the nano bubble generating assembly 2 and prepare nano bubble water, and in the process of circulation, the content of nano bubbles in the liquid in the water tank 1 is gradually increased; on the other hand, in the process of water circuit circulation, the bubbles in the water that do not meet the nano bubble standards are broken or separated from the water surface, and after repeated circulation, the effective content of nano bubbles in the water can be increased.

[0053] In this embodiment, by setting the water filter component 3, impurities in the water can be filtered out to purify the water and improve the water quality, and the various components and pipes of the drinking water machine can be effectively protected to avoid the formation of scale and improve the durability of the drinking water machine. In some embodiments, the water filter component 3 includes a first pp cotton filter element, an activated carbon filter element, a second pp cotton filter element and a first RO membrane arranged in sequence along the liquid flow direction. Specifically, the first pp cotton filter element is a 5umpp cotton filter element, and the second pp cotton filter element is a 1umpp cotton filter element.

[0054] In some other preferred embodiments, the water tank 1 includes at least two;

[0055] At the same time, the nano bubble generating assembly 2 is supplied with water from the same water tank 1 and delivers nano bubble water to the same water tank 1 .

[0056] For example, if Figure 1 As shown, the water tank 1 includes three parts, namely, water tank A, water tank B and water tank C. In this embodiment, after the water is purified by the water filter component 3, it is transported to water tank A, water tank B and water tank C in sequence until the liquid level in the water tank reaches the set liquid level. Water tank A supplies water to the nano bubble generating component 2 through the input pipe, and the nano bubble generating component 2 prepares nano bubble water and re-transports the prepared nano bubble water to water tank A through the output pipe; at the same time, water tank B and water tank C are in a static state. After the nano bubble content of the water in water tank A reaches the target content or reaches the set running time, the valve of water tank A is closed and the valve of water tank B is opened, that is, the nano bubble generating component 2 is changed to be supplied by water tank B, and the prepared nano bubble water is transported to water tank B. After the nano bubble content of the water in water tank B reaches the target content or reaches the set running time, the valve of water tank B is closed and the valve of water tank C is opened. In other words, the water supply and output of the nano bubble generating assembly 2 are switched in turn in the water tank A, the water tank B and the water tank C. In this way, at the same time, the nano bubble generator is supplied with water from the same water tank 1 and delivers nano bubble water to the same water tank 1, and the other water tanks 1 can be in a static state, so that the bubbles in the water that do not meet the nano bubble standards in the water tank 1 in a static state can be broken or separated from the water surface, so that the effective content of nano bubbles in the water can be increased.

[0057] It is worth mentioning that in this embodiment, three water tanks 1 are provided, and at the same time, one water tank is used to supply water to the nano bubble generating assembly 2 and receive the prepared nano bubble water, one water tank is used to output the nano bubble water for drinking, and one water tank is used to stand still so that the bubbles in the water that do not meet the nano bubble standard will burst or detach from the water surface, and the three do not interfere with each other. Such a configuration can satisfy the supply of nano bubble water for drinking without affecting the preparation of nano bubble water, and provide sufficient time for the bubbles in the water that do not meet the nano bubble standard to burst or detach, so as to increase the effective content of nano bubbles in the water.

[0058] In some other embodiments, a plurality of water tanks may be provided, and the plurality of water tanks may be connected in sequence through pipelines. Figure 1The water tank 1 includes three parts, namely, water tank A, water tank B and water tank C. After the water is purified by the water filter component 3, it is transported to the water tank A until the liquid in the water tank A reaches the preset liquid level. The water tank A supplies water to the nano bubble generating component 2 through the input pipe, the nano bubble generating component 2 prepares nano bubble water, and re-transports the prepared nano bubble water to the water tank A through the output pipe. After the water circuit between the water tank A and the nano bubble generating component 2 circulates for a set time, the nano bubble water in the water tank A is transported to the water tank B through the pipe under the action of the water pump, and after the transportation is completed, the water filter component transports the purified water to the water tank A again until the liquid in the water tank A reaches the preset liquid level; the water tank A supplies water to the nano bubble generating component 2 through the input pipe again, the nano bubble generating component 2 prepares nano bubble water, and re-transports the prepared nano bubble water to the water tank A through the output pipe. After the nano bubble water in water tank B is left to stand for a period of time, the water in water tank B is transported to water tank C through a pipeline under the action of a water pump, and the nano bubble water in water tank C is used for external supply. In this way, the nano bubble water can be supplied to the outside for drinking without affecting the preparation of nano bubble water; during the transportation of nano bubble water between water tank A, water tank B and water tank C, some bubbles in the nano bubble water that do not meet the nano bubble standard will break or detach from the water surface, which can make the nano bubble purity in the water.

[0059] Implementation Method 2

[0060] This embodiment discloses a drinking water machine. This embodiment is a further improvement made based on the first embodiment. The improvement is as follows: Figure 1 and Figure 2 As shown, the drinking water machine also includes:

[0061] The gas generator 4 is connected to the nano bubble generating component 2 and is used to provide the nano bubble generating component 2 with gas required for generating nano bubbles.

[0062] Specifically, in some embodiments, the gas generator 4 can be an oxygen production device. For example, the oxygen production device can use air separation technology to prepare oxygen, compress the air at a high density, and then use the different condensation points of the components in the air to separate the gas and liquid at a certain temperature, and then perform distillation to separate it into oxygen and nitrogen. Among them, oxygen is used to be transported to the nano bubble generating component 2 to generate nano bubbles. In some other embodiments, the gas generator 4 includes:

[0063] An electrolytic cell 41, used for electrolyzing liquid to generate gas, the electrolytic cell 41 having a liquid inlet and a gas outlet, the gas outlet being connected to the nano bubble generating assembly 2 to transport gas;

[0064] The electrolytic cell water tank 42 is connected to the liquid inlet and is used to transport the liquid required for electrolysis to the electrolytic cell 41 .

[0065] Specifically, the electrolyzer water tank 42 stores the liquid required for electrolysis; the electrolyzer water tank 42 is connected to the liquid inlet of the electrolyzer 41, and the liquid required for electrolysis is transported to the electrolyzer 41. The electrolyzer 41 electrolyzes the liquid to generate gas, and transports the gas to the nano bubble generating component 2 through the gas outlet for generating nano bubbles. Specifically, in this embodiment, water is stored in the electrolyzer water tank 42 and transported to the electrolyzer 41 through the liquid inlet, and the electrolyzer 41 electrolyzes the water to generate hydrogen and oxygen. In some embodiments, the liquid required for electrolysis is used to produce hydrogen and oxygen at the same time, and hydrogen or oxygen can be output to the nano bubble generating component 2 through the gas outlet. In this way, by selecting different structures of the electrolyzer 41, the position of the gas outlet is changed, that is, hydrogen or oxygen is transported to the nano bubble generating component 2 for preparing hydrogen nano bubble water and oxygen nano bubble water.

[0066] In some embodiments, a gas pump may be provided between the electrolytic cell and the nano bubble generating assembly, and the gas generated by electrolysis in the electrolytic cell 41 is delivered to the nano bubble generating assembly under the pumping action of the gas pump. By providing the gas pump, the output pressure of the gas generated by electrolysis in the electrolytic cell 41 can be increased to meet the gas pressure requirement of the nano bubble generating assembly. In addition, in some embodiments, in order to improve the gas preparation efficiency, a plurality of electrolytic cells 41 may be provided, and the plurality of electrolytic cells 41 are provided in parallel.

[0067] In some other preferred embodiments, the gas generator 4 further comprises:

[0068] The purification filter element 5 is disposed between the electrolytic cell 41 and the electrolytic cell water tank 42 , and is used for filtering the liquid transported from the electrolytic cell water tank 42 to the electrolytic cell 41 .

[0069] By setting the purification filter element 5, the liquid can be filtered and purified during the process of conveying the liquid from the electrolytic cell water tank 42 to the electrolytic cell 41. On the one hand, the electrolytic cell 41 and the pipeline can be effectively protected to avoid the formation of scale and improve the durability of the electrolytic cell 41. On the other hand, the purity of the liquid conveyed to the electrolytic cell 41 can be improved, thereby improving the purity of the gas generated by electrolysis in the electrolytic cell 41.

[0070] In some embodiments, the electrolytic tank water tank 42 can be connected to the water filter assembly 3 and supplied with water by the water filter assembly 3. The purpose of such a setting is that the water can be subjected to a first purification process through the water filter assembly 3 to inject the purified water into the electrolytic tank water tank 42. Since the electrolytic tank water tank 42 may contain impurities during long-term use. By setting the purification filter element 5, the water can be further purified. On the one hand, the purity of the water can be ensured. On the other hand, through two purification processes, the purity of the water can be further improved, thereby improving the purity of the gas generated by electrolysis in the electrolytic tank 41.

[0071] In some preferred embodiments, the water tank 1 is provided with a wastewater outlet;

[0072] The drinking water machine also includes:

[0073] A wastewater treatment component 6 , the input end of which is connected to the wastewater outlet, is used to treat the wastewater in the water tank 1 , and the output end of which is connected to the electrolytic cell water tank 42 .

[0074] The wastewater outlet provided in the water tank 1 is used to discharge the wastewater in the water tank 1. By providing the wastewater treatment component 6, the input end of the wastewater treatment component 6 is connected to the wastewater outlet, and the output end is connected to the electrolytic tank 42, so that the water in the water tank 1 can be purified and transported to the electrolytic tank 42 for electrolysis in the electrolytic tank 41. In this way, the wastewater that should be discharged from the water tank 1 can be reused, thereby reducing the preparation cost of nano bubble water.

[0075] Specifically, the wastewater treatment component 6 includes:

[0076] The second RO membrane 61 is used to filter waste water;

[0077] The wastewater pump 62 is connected to the wastewater outlet and is used to transport wastewater.

[0078] The wastewater pump 62 is connected to the wastewater outlet, and is used to extract the wastewater in the water tank 1 and pump it to the second RO membrane 61, providing the required pressure for the second RO membrane 61 to filter the wastewater; the water filtered by the second RO membrane 61 is transported to the electrolytic cell water tank 42.

[0079] Implementation Method 3

[0080] This embodiment is a further improvement based on the first embodiment and the second embodiment, and the improvement is that the nano bubble generating component 2 is further limited. Specifically, Figure 2 As shown, the nano bubble generating component 2 includes:

[0081] The nano bubble generator 21 has:

[0082] A gas inlet, used for inputting gas;

[0083] A liquid inlet, connected to the water tank 1, for inputting liquid;

[0084] The liquid outlet is connected to the water tank 1 and is used to output nano bubble water.

[0085] In this embodiment, gas enters the nano bubble generator 21 through the gas inlet, and water in the water tank 1 is pumped by a water pump and enters the nano bubble generator 21 from the liquid inlet through the input pipe; the nano bubble generator 21 produces nano bubble water, and the produced nano bubble water flows out through the liquid outlet and is transported to the water tank 1 through the output pipe.

[0086] It is worth mentioning that, since the volume of nanobubble water prepared by a single nanobubble generator 21 per unit time is limited, that is, the preparation efficiency of the nanobubble generator 21 is limited. Therefore, in some more preferred embodiments, such as Figure 2 As shown, there are multiple nano bubble generators 21, and the multiple nano bubble generators 21 are arranged in parallel. Through the multiple nano bubble generators 21 arranged in parallel, nano bubble water can be prepared at the same time, thereby improving the preparation efficiency.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them. Although the embodiments of the utility model are described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the utility model can still be modified or replaced by equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the utility model.
