One of the inlets may be in communication with the liner 2 via a conduit to allow at least one of gas or water in the liner 2 to enter the tank 1. When an inlet is provided in the tank 1, the inlet may be used for circulating gas or liquid. When a plurality of inlets are provided on the tank 1, each inlet may perform a different function, for example one for intake of air, one for intake of water, etc. In addition, the number of the output pipes on the tank body 1 may be at least one, and correspondingly, the number of the outlets may be one or more, which is not particularly limited herein.

Referring to fig. 4A to 4D, the jet structure may be a variable cross-sectional area portion 311 formed at the input pipe 31 near the inlet 310.

As shown in fig. 4A, the variable cross-sectional area portion 311 may be an elliptical opening formed at the inlet 310 of the input pipe 31.

In this embodiment, the inner container 2 may be communicated with the tank 1 to form a gas storage mechanism, and the gas storage mechanism is used for storing gas used for preparing micro-bubble water. Specifically, the gas storage mechanism may further include a pipeline for connecting the inner container 2 and the tank 1, in addition to the inner container 2 and the tank 1 that can be mutually communicated.

Specifically, the inner container 2 and the tank body 1 may be connected in series along the fluid flow direction, and after the water is discharged and the air is supplemented into the air storage mechanism, a predetermined amount of air may be stored in the inner container 2. The specific predetermined amount of gas may be set according to the actual use requirement, and in general, when the water consumption requirement is large, the predetermined amount of gas stored in the liner 2 may be relatively more, or even the gas may be stored in the liner; when the water consumption is small, the predetermined amount of gas stored in the inner container 2 may be relatively small, and in particular, the present application is not limited thereto. In a preferred case, the micro bubble water prepared by combining the gas stored in the inner container 2 with the gas in the tank 1 can satisfy the use amount of one time of the user. When the water is discharged to the air storage mechanism for air supplement, after the air supplement of the inner container 2 is completed, the air supplement of the tank body 1 can be performed. Wherein, the air supply to the tank body 1 is also completed at the same time of the air supply to the water discharge of the connecting pipeline between the liner 2 and the tank body 1.

After the water drainage and air supplement of the air storage mechanism are completed, the air in the air storage mechanism can be compressed by using a pressurizing source. Specifically, a predetermined amount of gas in the liner 2 can be compressed into the tank 1, and pressure is provided for mixing the gas and the liquid in the tank 1 of the gas storage mechanism, so as to prepare the micro-bubble water.

In this embodiment, the pressurizing source is capable of compressing the gas in the gas storage mechanism and providing pressure for mixing the gas and the liquid in the gas storage mechanism. Specifically, the boost source may include at least one of the following or a combination thereof: pump 3, liquid with a predetermined pressure. The pump 3 may be a water pump, when the water pump is started to operate, the water pump may boost pressure of water flowing through the water pump, and may boost pressure of the tank 1 communicated with the water pump, that is, when micro-bubble water is prepared, the water pump may provide pressure required when gas and water are mixed. In addition, the water pump can also be used as a power device for water circulation of the water heater system. Generally, a water pump may be provided in the water heater system to provide the power for the water circulation.

In this embodiment, when the pressurizing source is a water pump, it can utilize the existing water pump in the water heater system, without separately adding a water pump, thereby being beneficial to saving the cost, saving the space of the whole water heater system, and optimizing the product structure. Of course, the pressurizing source may also be in the form of other pressurizing devices capable of providing pressure, and the specific application is not limited in this regard.

In addition, the pressurizing source can be liquid with preset pressure, such as water with certain pressure, when the water with pressure flows to the gas storage mechanism, the pressurized source can compress gas in the gas storage mechanism, and the pressurized water can well realize gas-liquid mixing when colliding with compressed air.

In this embodiment, the water heater system may include: a first state of draining and supplementing air to the air storage mechanism and a second state of compressing air in the air storage mechanism and mixing air and liquid in the air storage mechanism; correspondingly, in the first state, the inner container 2 and the tank body 1 can be communicated to form a gas storage mechanism; in the second state, the pressurizing source can compress the gas in the gas storage mechanism and provide pressure for mixing the gas and the liquid in the gas storage mechanism.

Specifically, the first state of the water heater system when in use is a water draining and air supplementing state for draining and supplementing air to the air storage mechanism, and the air needed by preparing micro bubbles is supplemented into the air storage mechanism of the water heater system by draining and supplementing air to the air storage mechanism. The second shape body of the water heater system is in a gas-liquid mixing state of compressing the gas in the gas storage mechanism and mixing the gas and the liquid in the gas storage mechanism when the water heater system is in use.

When the gas and the liquid are mixed, a predetermined amount of gas in the liner 2 can be compressed into the tank 1, then water under the action of the pressurizing source can be sprayed into the tank 1 through the inlet to be mixed with the gas in the tank 1, and the tank 1 is subjected to gas-liquid mixing so as to prepare micro-bubble water to be supplied to a user terminal.

As shown in fig. 2B, in particular, the tank 1 has opposite top and bottom ends, and the tank 1 is generally top-up and bottom-down when in use. The tank body 1 is internally provided with a pipe body extending from the bottom end to the top end, and the inlet is formed by a port of the pipe body close to the top end. When the tank body stores gas, pressurized water under the pressurizing effect of the pressurizing source is sprayed upwards through the pipe body, and is initially contacted with the gas in the tank body, so that a certain gas dissolving effect is achieved; further collide with the inner wall of the tank body near the top end, the pressurized water diffuses in all directions to form liquid drops and liquid films, and air is involved in the process of impacting underwater, so that better secondary gas dissolution is realized. In the embodiment, the pressure water can strike the inner wall of the tank body and then is dissolved with the gas for the second time, so that the gas dissolving efficiency is relatively high, and the time for preparing the micro bubbles is shortened.

Naturally, the gas in the tank body 1 may be compressed into the liner 2, and then the gas and the liquid may be mixed in the liner 2; or the gas-liquid mixing may be performed in the liner 2 and the tank 1, respectively, and the specific manner and the mixing position of the gas-liquid mixing are not particularly limited herein.

The water heater system may further comprise a pressure regulating device 4 arranged downstream of the gas storage mechanism.

The pressure regulating means 4 may be provided at a downstream location of the overall water heater system, the pressure regulating means 4 being adapted to maintain the pressure between the air reservoir itself within a predetermined range. Specifically, the pressure adjusting device 4 may be one of pressure adjusting valves, such as a self-operated pressure adjusting valve, such as a gas release device, etc., a hydraulic pressure controlling valve, such as a relief valve, an electronic expansion valve, a thermal expansion valve, etc. with controllable pressure, or may be other forms, and specifically, the control principle of the pressure adjusting device 4 may be different according to the specific structure of the pressure adjusting device 4, which is not limited herein specifically.

Referring to fig. 3A, for example, at least one stage of the variable aperture structure is provided in the direction of fluid flow, and the pressure adjusting device 4 includes a hollow pipe body in which at least one throttling member is provided. The throttling component can be of a structure with the aperture smaller than the inner diameter of the pipe body. In addition, the throttle plate can be sequentially provided with the flow holes with sequentially increased number of holes along the fluid flow direction, so that the flow cross section area is gradually increased along the fluid flow direction on the whole. When fluid flows through the throttling mechanism, the pressure of the fluid is correspondingly increased due to the fact that the flow cross section area is suddenly reduced, and therefore the function of maintaining the pressure can be achieved.

Referring to fig. 3B, the pressure adjusting device 4 may be further provided with a back pressure spring having a variable flow cross-sectional area, or other throttling mechanism, which is not particularly limited herein. Other variations will occur to those skilled in the art upon the benefit of this disclosure, and it is intended that the application encompass both functions and effects similar to those described herein.

The preset pressure is the pressure required by gas-liquid mixing in the gas storage mechanism, and is favorable for generating and maintaining micro bubbles. For example, when the pressurizing source is a water pump, the water pump is disposed upstream of the liner 2, and when the water pump is turned on, the pressure adjusting device 4 can maintain the pressure between the water pump and the pressure adjusting device 4 to be 0.2 mpa or more. When the pressure between the water pump and the pressure regulating device 4 is controlled to be more than 0.2 megapascals by the pressure regulating device 4, the preset pressure is the pressure required by gas-liquid mixing in the liner 2, which is beneficial to generation and maintenance of micro bubbles. In particular, on the one hand, when the pressure is above 0.2 megapascals, more air is dissolved in water, so that micro-bubble water with higher solubility is formed; on the other hand, when the micro-bubble water flows in the pipeline, the state of the micro-bubble water is maintained, and bubbles in the water are prevented from becoming larger gradually.

Of course, the scope of the predetermined pressure is not limited to the above list, and other modifications can be made by those skilled in the art in light of the technical spirit of the present application, and any functions and effects achieved by the present application are intended to be included in the scope of the present application.

The water heater system may further comprise a pressure detection device for detecting the pressure of the water heater system.

When the gas-liquid mixture is performed in the tank 1, the pressure detecting device may include: a first pressure detecting means 81 for detecting whether the pressure in the tank 1 reaches a predetermined operating pressure, and a second pressure detecting means 82 for detecting whether the pressure in the tank 1 is lower than a predetermined holding pressure.

The first pressure detecting device 81 and the second pressure detecting device 82 may be disposed on a pipe line through which the tank 1 communicates, for example, a pipe line between the tank 1 and the pressure adjusting device 4. The first pressure detecting device 81 and the second pressure detecting device 82 may be electrically connected to a controller. When the pressure of the tank 1 detected by the first pressure detecting device 81 reaches a predetermined working pressure, the controller may control the water heater system to enter a second state of gas-liquid mixing, so as to perform gas-liquid mixing. When the pressure of the tank 1 detected by the first pressure detecting device is lower than the holding pressure, the controller can control the water heater system to stop the second state of gas-liquid mixing, so that the water heater system can be ensured to stably prepare micro-bubble water.

The microbubbles refer to bubbles having a size of several or tens of micrometers. The surface of the microbubbles has weak negative charges in water, and can adsorb substances such as grease, protein and the like, thereby carrying them away from skin, hair and the like. When the bath is performed by using the microbubble water with microbubbles, a large amount of microbubbles per minute can penetrate into the parts such as the hair roots which are difficult to clean, and dirt such as sebum, grease and the like accumulated in the parts can be thoroughly removed.

In addition, the micro-bubble water also has a unique sterilization effect. Specifically, the sterilization process of the microbubble water comprises two processes of attraction and sterilization, wherein the microbubbles are provided with static electricity and can adsorb bacteria and viruses in the water body; then, a large amount of free radicals are excited around the bubbles along with the collapse of the bubbles, and the adsorbed bacterial viruses are killed by the ultrahigh temperature and high pressure generated by the collapse. The sterilization process is a complete physical sterilization process which is essentially different from the conventional disinfection sterilization method, so that the sterilization process is more environment-friendly and healthy compared with the conventional chemical sterilization process.
