[0029] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figures 1 to 6As shown, a bubble water machine is provided in this embodiment, including a body 1, a nozzle 2, a pressure relief component 3, a flow detection structure 4 and a controller, the nozzle 2 is arranged on the body 1, and is suitable for connecting with the water bottle 9, and an air inlet 21 and an exhaust port structure 22 are provided on the nozzle 2, and the air inlet 21 is suitable for communicating with the air outlet of the gas bottle 8; the pressure relief component 3 is arranged on the body 1, and is connected with the exhaust port structure 22; the flow detection structure 4 is arranged on the flow path between the exhaust port structure 22 and the pressure relief component 3, and is used to detect the gas flow rate; the controller is communicatively connected with the flow detection structure 4, and is suitable for receiving the gas flow rate detected by the flow detection structure 4, and converting the dissolved amount of carbon dioxide gas in the water bottle 9 according to the gas flow rate.

[0034] The bubble water machine is provided with a flow detection structure 4, which detects the gas flow rate on the pressure relief path, converts the dissolved amount of carbon dioxide gas in the water bottle 9, and achieves relatively accurate control of the dissolved amount of carbon dioxide. The gas flow rate on the pressure relief path represents the gas flow rate of carbon dioxide precipitated from the bubble water in the water bottle 9, which is the carbon dioxide gas precipitated after the carbon dioxide gas of corresponding pressure is injected into the water bottle 9, that is, the carbon dioxide gas that is still undissolved after reaching the corresponding pressure. The gas flow rate of the carbon dioxide gas is directly related to the dissolved amount of carbon dioxide gas in the bubble water, and the dissolved amount of carbon dioxide gas can be measured and controlled relatively accurately.

[0035] In some existing sparkling water machines, the gas flow detection device is arranged on the air intake path, which can detect the amount of carbon dioxide gas entering the water bottle 9. However, during the research process, the researchers found that the amount of carbon dioxide gas dissolved in water or beverages is different, and the amount of carbon dioxide gas dissolved in liquids with different pressures is also different. Therefore, the correlation between the flow rate of carbon dioxide gas entering the water bottle 9 and the flow rate of carbon dioxide gas entering the water bottle 9 is inaccurate, which can easily cause detection errors and cause the user to be unable to obtain the desired sparkling water. The gas flow detection device in this embodiment is arranged on the flow path between the exhaust port structure 22 and the pressure relief component 3. The detection result can be converted into the dissolved amount. The correlation between the two is relatively large, and the control of the dissolved amount of carbon dioxide gas is more accurate.

[0036] In this embodiment, the communication connection includes multiple connection modes such as connection through a wire and connection through a network, and the network connection includes wireless networks such as WIFI, 2G, 3G, 4G and other wireless networks.

[0037] The water bottle 9 in this embodiment is a container bottle, which can be used to hold water or beverages such as juice. The bubble water machine also includes a gas cylinder 8 for holding compressed carbon dioxide gas.

[0038] The bubble water machine in this embodiment also includes a pressing structure 5, which is suitable for controlling the opening or closing of the air outlet; the exhaust port structure 22 includes a first exhaust port, and the pressure relief assembly 3 includes a first pressure relief valve 31 connected to the first exhaust port, and the first pressure relief valve 31 is linked to the pressing structure 5, and is suitable for opening when the pressing structure 5 closes the air outlet, and closing when the pressing structure 5 opens the air outlet; the flow detection structure 4 is arranged on the flow path between the first exhaust port and the first pressure relief valve 31.

[0039] The first pressure relief valve 31 is linked to the pressing structure 5 and is suitable for opening when the pressing structure 5 closes the air outlet. The flow detection structure 4 is used to detect the gas flow rate of the carbon dioxide gas released after the inflation is completed, that is, the flow rate of the gas not dissolved in the water. The dissolved amount of carbon dioxide in the bubble water can be calculated relatively accurately based on the flow rate.

[0040] In the sparkling water machine in this embodiment, the pressing structure 5 includes a button assembly 51 and a pressing lever 52. The button assembly 51 is arranged on the body 1 and is located above the nozzle 2; one end of the pressing lever 52 is rotatably connected to the gas cylinder fixing frame 6, and the other end is linked to the button assembly 51; the gas cylinder fixing frame 6 is arranged on the body 1 at a position away from the nozzle 2, and the gas cylinder fixing frame 6 is suitable for connecting to the gas cylinder 8; the first pressure relief valve 31 is arranged on the gas cylinder fixing frame 6 and is linked to the pressing lever 52.

[0041] The button assembly 51 is arranged on the top of the machine body 1 and can move up and down relative to the top of the machine body 1; the gas cylinder fixing frame 6 is used to fix the gas cylinder 8, and the gas cylinder fixing frame 6 is connected to the position of the machine body 1 away from the nozzle 2, so that the positions of the gas cylinder 8 and the water bottle 9 are staggered. When the pressing lever 52 is pressed and moved downward, the pressing lever 52 moves with the button assembly 51, driving the gas valve at the bottle mouth of the gas cylinder 8 to open; when the pressing lever 52 is not pressed, the pressing lever 52 and the button assembly 51 return to their original positions under the elastic force of their respective elastic structures, and the gas valve at the bottle mouth of the gas cylinder 8 is closed.

[0042] In the bubble water machine of this embodiment, the pressure relief assembly 3 also includes a first exhaust pipe 32 , one end of the first exhaust pipe 32 is connected to the first exhaust port, and the other end is connected to the first pressure relief valve 31 , and the flow detection structure 4 is arranged on the first exhaust pipe 32 .

[0043] The first exhaust port is connected to the first pressure relief valve 31 through the first exhaust pipe 32, so that the first pressure relief valve 31 can be set at a corresponding position. The position of the first pressure relief valve 31 is not restricted and is more flexible. The flow detection structure 4 is set on the first exhaust pipe 32, the flow rate in the first exhaust pipe 32 is relatively stable, and the measured result is more accurate.

[0044] In this embodiment, the pressure relief assembly 3 also includes a second pressure relief valve 33; the exhaust port structure 22 includes a second exhaust port, the second exhaust port is connected to the second pressure relief valve 33, the second pressure relief valve 33 is communicated with the controller, and the first pressure relief valve 31 is suitable for opening after the second pressure relief valve 33 is opened.

[0045] The second pressure relief valve 33 is an automatic pressure relief valve having a certain pressure maintaining capability. When the gas pressure in the sparkling water machine reaches the preset pressure of the second pressure relief valve 33, the second pressure relief valve 33 automatically opens.

[0046] The second pressure relief valve 33 is arranged on the gas cylinder fixing frame 6; the gas cylinder fixing frame 6 is suitable for connecting with the gas cylinder 8 and is arranged at a position on the body 1 away from the nozzle 2; the pressure relief assembly 3 also includes a second exhaust pipe 34, one end of the second exhaust pipe 34 is connected with the second exhaust port, and the other end is connected with the second pressure relief valve 33. The second exhaust port is connected with the second pressure relief valve 33 through the second exhaust pipe 34, so that the second pressure relief valve 33 can be arranged at a corresponding position, and the position of the second pressure relief valve 33 is not restricted, which is more flexible.

[0047] The bubble water machine in this embodiment further includes a display screen 7, which is arranged outside the machine body 1. The display screen 7 is connected to the controller for communication and is suitable for displaying the dissolved amount converted by the controller.

[0048] The display screen 7 is suitable for displaying the dissolved amount of carbon dioxide gas. The user can judge whether the drinking requirements are met based on the dissolved amount displayed on the display screen 7. If not, the user can press the button assembly 51 a second time to introduce carbon dioxide gas into the bubble water.

[0049] In this embodiment, the display screen 7 is arranged on the side of the head of the machine body 1, so that the user can observe the dissolution amount.

[0050] As a convertible implementation, the display screen 7 may also be arranged on the top of the head of the machine body 1.

[0051] The working process of the bubble water machine in this embodiment includes: pressing the button assembly 51 downward, one end of the pressing lever 52 moves downward under the linkage of the button assembly 51, the gas valve of the gas cylinder 8 is pushed open, and the carbon dioxide gas enters the nozzle 2 through the air inlet pipe and the air inlet 21, and enters the water or beverage in the water bottle 9 through the nozzle 2. At this time, the other end of the pressing lever 52 is tilted, and the first pressure relief valve 31 is closed. After a period of inflation, part of the carbon dioxide is dissolved in the water or beverage, part of the carbon dioxide is discharged through the second exhaust pipe 34 and the second pressure relief valve 33, and the other part of the gas is discharged through the first exhaust pipe 32 and the first pressure relief valve 31 after the button assembly 51 and the pressing lever 52 return to their original positions.

[0052] The exhaust step of the bubble water machine in this embodiment includes: when the pressure in the water bottle 9 of the bubble water machine is greater than the pressure holding pressure of the second pressure relief valve 33, the second pressure relief valve 33 is opened, and part of the carbon dioxide gas is discharged through the second pressure relief valve 33, at this time, the button assembly 51 is released, the button assembly 51 and the pressing lever 52 are both restored to their original positions, the gas valve is closed, and no more carbon dioxide gas is introduced into the water bottle 9, the first pressure relief valve 31 is opened, and the gas less than the pressure holding pressure is discharged through the first pressure relief valve 31. When the excess gas in the water bottle 9 is exhausted, the bubble water in the water bottle 9 begins to precipitate carbon dioxide gas due to the reduction of the external pressure, and the precipitation speed of carbon dioxide gas depends on the dissolved amount of carbon dioxide in the bubble water, the flow rate is small and stable, the flow detection structure 4 starts to work, and the controller converts the flow rate data into the dissolved amount of carbon dioxide data and displays it on the display screen 7, and the conversion data of the controller comes from a large number of experiments by the R&D personnel. After reading the dissolved amount displayed on the display screen 7, the user can perform secondary inflation according to the personal requirements for the dissolved amount of carbon dioxide gas.

[0053] When the button assembly 51 is first released, a large amount of gas in the water bottle 9 is discharged, and the flow rate of the flow detection structure 4 is relatively large. The measured value at this time is not used as a reference and is not converted.

[0054] In this embodiment, the flow detection structure 4 is a gas flow meter.

[0055] In this embodiment, the gas flow meter includes a flow rate sensor for detecting the gas flow rate and a temperature sensor for detecting the gas temperature, and the controller is adapted to convert the dissolved amount according to the gas flow rate and the gas temperature, thereby avoiding the influence of temperature on the speed of carbon dioxide gas precipitation, and making the detection result more accurate.

[0056] In this embodiment, the nozzle 2 includes a first connection part and a second connection part suitable for detachably connecting with the water bottle 9, and the first connection part is suitable for detachably connecting with the body 1 and suitable for detachably connecting with the portable inflatable device. When the user needs to go out for use, the water bottle 9 is connected to the second connection part, and the first connection part is removed from the body 1 and detachably connected to the portable inflatable device. The portable inflatable device replaces the gas cylinder 8 in the body 1 to inject carbon dioxide gas into the liquid in the water bottle 9, so that the portable inflatable device is used to prepare sparkling water in the small-capacity water bottle 9 when going out. When the user needs to use the bubble water machine at home, the portable inflation device can be set on the body 1 of the bubble water machine, or stored near the bubble water machine; the nozzle 2 structure is connected to the body 1 through the first connecting part, connecting the water bottle 9 with the bubble water machine, and directly using the large air bottle 8 of the bubble water machine itself to prepare the bubble water of the large-capacity water bottle 9 to meet the bubble water needs of more people at home, so that one bubble water machine can meet the preparation needs of large-capacity bubble water and small-capacity bubble water, which can be achieved by users purchasing one bubble water machine, and the cost is relatively low.

[0057] The nozzle 2 structure is detachably connected to the body 1, which facilitates cleaning and maintenance of the nozzle 2 structure, so that liquid is unlikely to remain on the nozzle 2 structure and bacteria are unlikely to grow.

[0058] The water bottle 9 in this embodiment is a container bottle, which can be used to hold water or beverages such as juice. The sparkling water machine also includes a gas cylinder 8, and the portable gas filling device includes a gas tank, and both the gas cylinder 8 and the gas tank contain carbon dioxide gas, which is not limited here.

[0059] The portable inflatable device is suitable for being arranged on the body 1 when the first connecting part is connected to the body 1. The portable inflatable device is convenient for storage to prevent loss. A storage space is provided on the body 1, and the portable inflatable device is suitable for being placed in the storage space. It is convenient for storage of the portable inflatable device to prevent loss; the portable inflatable device is also stored, which protects the portable inflatable device while ensuring the aesthetics of the whole device. The storage space is located between the button assembly 51 and the gas cylinder fixing frame 6, and the space between the button assembly 51 and the gas cylinder fixing frame 6 is reasonably utilized; the pressing lever 52 is provided with an avoidance opening suitable for avoiding the portable inflatable device, so that the pressing lever 52 will not interfere with the portable inflatable device.

[0060] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
