Detailed implementation manners

[0062] To make the purpose, technical solutions and advantages of the present invention clearer and more definite, the following further elaborates on the present invention by way of examples with reference to the accompanying drawings. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0063] Please refer to simultaneously Figures 1-12, the present invention provides some embodiments of a bubble machine.

[0064] As Figure 1 , Figure 2 and Figure 4 shown, the bubble machine of the present invention includes: a liquid reservoir 10, a gas reservoir 20, and a gas-liquid mixer 30; the liquid reservoir 10 is used to store liquid, and the gas reservoir 20 is used to store carbon dioxide.

[0065] Specifically, the liquid reservoir 10 stores liquid, and the liquid can be water. As Figure 2 and Figure 3 shown, a filter 13 is provided in the liquid reservoir 10, so ice cubes can be added to the liquid reservoir 10, and the ice cubes are blocked by the filter 13 and cannot enter the gas-liquid mixer 30. The ice cubes can reduce the temperature of the liquid to a preset temperature range, which is beneficial to increasing the solubility of carbon dioxide. When the liquid is water, the preset temperature range is 1°C to 6°C. The gas reservoir 20 stores high-pressure carbon dioxide, which can be liquefied carbon dioxide. Both the liquid reservoir 10 and the gas reservoir 20 are connected to the gas-liquid mixer 30. The liquid reservoir 10 injects the liquid into the gas-liquid mixer 30, and then the gas reservoir 20 injects carbon dioxide gas into the gas-liquid mixer 30. Since the pressure of the carbon dioxide gas is greater than the atmospheric pressure when it is injected into the gas-liquid mixer 30, the solubility of the carbon dioxide gas in the liquid is higher.

[0066] As Figure 5 , Figure 6 and Figure 9 shown, the gas-liquid mixer 30 includes:

[0067] A housing 31, the bottom structure 31a of the housing 31 forms a first air inlet 311, a liquid inlet 312, and an outlet 313. The first air inlet 311 is connected to the gas reservoir 20, the liquid inlet 312 is connected to the liquid reservoir 10, and a drain valve 3131 is provided at the outlet 313; the top structure 31b of the housing 31 is a spherical crown-shaped top structure;

[0068] A rotating member 32, with both ends rotatably connected to the bottom structure 31a of the housing 31 and the top structure 31b of the housing 31 respectively;

[0069] A stirring driving member 33, arranged outside the housing 31 and used to drive the rotating member 32 to rotate;

[0070] A plurality of arc-shaped frames 34, arranged on the rotating member 32;

[0071] Among them, the plurality of arc-shaped frames 34 form a spherical crown-shaped structure.

[0072] Specifically, the housing 31 is used to contain liquid and carbon dioxide gas. The carbon dioxide gas enters the interior of the housing 31 from the first inlet 311, and the liquid enters the interior of the housing 31 from the liquid inlet 312. After the carbon dioxide dissolves in the solution, a bubble liquid is formed. When the liquid discharge valve 3131 is specifically controlled to open, the bubble liquid flows out from the outlet 313. The housing 31 is divided into two parts, namely the bottom structure 31a and the top structure 31b. The first inlet 311 is arranged on the bottom structure 31a, so that the carbon dioxide entering the housing 31 from the first inlet 311 will first contact the liquid of the bottom structure 31a, increasing the contact probability between the carbon dioxide and the liquid. The top structure 31b of the housing 31 is a spherical crown-shaped top structure. When the rotating member 32 drives the liquid to rotate, the liquid forms a circulating flow. The flow direction of the circulating liquid is that the liquid in the middle sinks, the liquid around floats, the liquid below diffuses outward, and the liquid above concentrates inward, finally presenting a shape with a high periphery and a low middle. The use of the spherical crown-shaped top structure is conducive to the rapid concentration of the liquid above to the middle, accelerating the circulating flow of the liquid, and further increasing the contact probability between the carbon dioxide and the liquid. Of course, when the rotation speed of the rotating member 32 is relatively high, the liquid around may reach the highest point of the spherical crown-shaped top structure, and the liquid is mainly located near the inner wall of the housing 31, and a state of mutual blending of gas and liquid is formed near the center of the housing 31.

[0073] The arc-shaped frame 34 is used as the stirring structure. A plurality of arc-shaped frames 34 form a spherical crown structure. The spherical crown structure is located at the center of the spherical crown-shaped top structure. The ratio of the radius of the spherical crown structure to the radius of the spherical crown-shaped top structure is 1 / 3 to 2 / 3. The stirring drive member 33 drives the rotating member 32 and the arc-shaped frame 34 to rotate, thereby driving the liquid to form a shape with a high periphery and a low middle. The arc-shaped frame 34 can span the liquid phase and the gas phase, and it is easier to overcome the surface tension of the liquid, stir and break the liquid surface. The liquid can enter the gas phase to form liquid droplets, and the gas can enter the liquid phase to form bubbles, which is beneficial to the contact between the carbon dioxide and the liquid and the dissolution of the carbon dioxide in the liquid.

[0074] Through the cooperation of the spherical crown-shaped top structure and the spherical crown structure, the present application accelerates the circulating flow of the liquid, promotes the mutual blending of the liquid phase and the gas phase, increases the possibility of the carbon dioxide contacting the liquid and dissolving in the liquid, and thus increases the concentration of the carbon dioxide in the liquid.

[0075] In a preferred implementation manner of the embodiment of the present invention, as Figure 6 shown, the top structure 31b of the housing 31 is provided with a first liquid level gauge 314 and a second liquid level gauge 315.

[0076] Specifically, the amount of the liquid cannot be too much. If there is too much liquid, the space for gas in the housing 31 will be less, which may lead to too high air pressure. The amount of the liquid cannot be too little either. If there is too little liquid, the carbon dioxide in the liquid will easily reach saturation and is not sufficient to dissolve an appropriate amount of carbon dioxide. The top structure 31b of the housing 31 is provided with two liquid level gauges, namely a first liquid level gauge 314 and a second liquid level gauge 315. The amount of the injected liquid is determined by the liquid level gauges, and the amount of the liquid is detected when the stirring driving member 33 is not started. The heights of the first liquid level gauge 314 and the second liquid level gauge 315 are different. For example, the height of the first liquid level gauge 314 is higher than that of the second liquid level gauge 315. If the liquid level is lower than the position of the second liquid level gauge 315 and the second liquid level gauge 315 does not detect the liquid, then the liquid needs to be replenished. If the liquid level is higher than the position of the first liquid level gauge 314 and both the first liquid level gauge 314 and the second liquid level gauge 315 detect the liquid, then the excess liquid needs to be discharged. When the first liquid level gauge 314 does not detect the liquid and the second liquid level gauge 315 detects the liquid, and the liquid level is between the first liquid level gauge 314 and the second liquid level gauge 315, the amount of the liquid is appropriate.

[0077] In a preferred implementation manner of the embodiment of the present invention, as Figures 9-11 shown, the arc-shaped frame 34 includes:

[0078] An extension part 341, which is arranged to extend along the radial direction of the rotating part 32;

[0079] An arc part 342, the upper end of the arc part 342 is connected to the rotating part 32, and the lower end of the arc part 342 is connected to the extension part 341;

[0080] Wherein, the first liquid level gauge 314 is higher than the upper end of the arc part 342; the second liquid level gauge 315 is located between the upper end and the lower end of the arc part 342.

[0081] Specifically, the extension part 341 is located below the arc part 342, and the extension part 341 fixes the lower end of the arc part 342 on the rotating part 32. The position of the first liquid level gauge 314 is higher than the upper end of the arc part 342, and the position of the second liquid level gauge 315 is between the upper end and the lower end of the arc part 342. During the rotation of the arc-shaped frame 34, the upper part of the arc part 342 is mainly located in the gas phase, and the lower part of the arc part 342 is mainly located in the liquid phase. The extension parts 341 of each arc-shaped frame 34 can be connected to each other, improving the strength of the spherical crown structure.

[0082] In a preferred implementation manner of the embodiment of the present invention, as Figures 5-6As shown, the top structure 31 b of the shell 31 is formed with a second air inlet 316 , the second air inlet 316 is connected to a first air pump 317 , and the second air inlet 316 is higher than the first liquid level gauge 314 .

[0083] Specifically, after the bubble liquid is prepared, it can be discharged from the outlet 313. In order to discharge the bubble liquid as quickly and fully as possible, the first air pump 317 delivers air from the second air inlet 316 into the housing 31, thereby accelerating the discharge speed of the bubble liquid and discharging as much bubble liquid as possible.

[0084] In a preferred implementation of the embodiment of the present invention, Figures 6-8 As shown, the second air inlet 316 is also connected to an overpressure exhaust component 318 .

[0085] Specifically, the second air inlet 316 can also be connected to the overpressure exhaust component 318 to prevent the air pressure in the housing 31 from being too high. After the bubble liquid is prepared, the overpressure exhaust component 318 is also required to exhaust air to reduce the pressure of the gas in the housing 31 to atmospheric pressure or slightly above atmospheric pressure.

[0086] In a preferred implementation of the embodiment of the present invention, Figure 5 , Figure 7 and Figure 8 As shown, the overpressure exhaust assembly 318 includes:

[0087] A pressure relief device 3181, an overpressure protector 3182, an exhaust valve 3183 and a controller 3184; the controller 3184 is used to control the exhaust valve 3183 to open or close. When the air pressure in the shell 31 exceeds a first pressure value, the pressure relief device 3181 opens and releases pressure; when the air pressure in the shell 31 exceeds a second pressure value, the overpressure protector 3182 opens and exhausts gas. The second pressure value is greater than the first pressure value.

[0088] Specifically, the exhaust valve 3183 is used for active exhaust. When the bubble liquid is prepared, the exhaust valve 3183 is opened by the controller 3184 to reduce the air pressure in the shell 31 to atmospheric pressure or slightly above atmospheric pressure. The pressure relief device 3181 and the overpressure protector 3182 are used for passive exhaust. If the air pressure is high and exceeds the first pressure value, the pressure relief device 3181 discharges the gas at a certain flow rate to prevent the air pressure from exceeding the first pressure value. If the air pressure continues to increase and exceeds the second pressure value, the overpressure protector 3182 is destroyed and the gas is quickly discharged to prevent the shell 31 from being damaged due to excessive air pressure.

[0089] In a preferred implementation of the embodiment of the present invention, Figures 9-11 As shown, the rotating member 32 includes:

[0090] The rotating seat 321 rotates relative to the bottom structure 31a of the housing 31;

[0091] A first magnet 322, located within the rotating base 321;

[0092] A rotating shaft 323, snap-connected to the rotating base 321;

[0093] Wherein, the arc-shaped frame 34 is arranged on the rotating shaft 323.

[0094] Specifically, the rotating base 321 can rotate relative to the bottom structure 31a of the housing 31. A first magnet 322 is arranged within the rotating base 321. The rotating shaft 323 is detachably connected to the rotating base 321. A through-hole 3211 is formed at the center of the rotating base 321. The rotating shaft 323 is a hollow shaft, and the shaft hole of the rotating shaft 323 communicates with the through-hole 3211. The rotating base 321 is disc-shaped.

[0095] In a preferred implementation manner of the embodiment of the present invention, as Figure 9 and Figure 11 shown, the stirring driving member 33 includes:

[0096] A motor 331;

[0097] A rotating disc 332, connected to the output shaft of the motor 331;

[0098] A second magnet 333, located within the rotating disc 332;

[0099] Wherein, the rotating disc 332 is located at the corresponding position of the rotating base 321.

[0100] Specifically, the motor 331 drives the rotating disc 332 and the second magnet 333 to rotate, and drives the first magnet 322, the rotating base 321 and the rotating shaft 323 to rotate together. The rotating disc 332 and the rotating base 321 do not contact each other. In this non-contact manner, it is not easy for the housing 31 to have leakage problems.

[0101] As Figure 9 and Figure 12 shown, a shaft portion 3212 is provided in the through-hole 3211. The bottom structure 31a of the housing 31 includes:

[0102] A peripheral portion 31a1, formed with a central hole 31a3;

[0103] A boss portion 31a2, hermetically connected to the central hole 31a3;

[0104] Wherein, a limiting groove 31a4 is formed on the upper surface of the boss portion 31a2, and the shaft portion 3212 rotates within the limiting groove 31a4.

[0105] Specifically, a gap is formed between the boss portion 31a2 and the rotating base 321. The rotating disk 332 is inserted into the boss portion 31a2, and the rotating base 321 and the rotating disk 332 are respectively located on the inner and outer sides of the boss portion 31a2. When the rotating base 321 rotates, the water in the gap spreads around, and air in the shaft hole of the rotating shaft 323 and the through hole 3211 is replenished into the limiting groove 31a4, which is beneficial to reducing the resistance of the rotation of the shaft portion 3212. A clearance groove 3321 is provided on the rotating disk 332. The clearance groove 3321 is located at the corresponding position of the limiting groove 31a4 to avoid the sunken limiting groove 31a4. The boss portion 31a2 can be made of a metal material, which is beneficial to improving the wear resistance of the boss portion 31a2. The shaft portion 3212 is not easily worn in the limiting groove 31a4, and it is also convenient to replace the boss portion 31a2.

[0106] In a preferred implementation manner of the embodiment of the present invention, as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the bubble machine further includes:

[0107] A mixing bin 40, which is communicated with the liquid discharge valve 3131;

[0108] At least one storage container, which is arranged in the mixing bin 40;

[0109] At least one second air pump 50, and the second air pump 50 is communicated with the corresponding storage container;

[0110] Wherein, the storage container is used for storing additives.

[0111] Specifically, the mixing bin 40 has a bin opening. After the bubble liquid is prepared, other additives can also be mixed in. Specifically, the bubble liquid and the additives are both injected into the mixing bin 40, mixed in the mixing bin 40, and flow out from the bin opening. The additives can be syrup, electrolyte solution, fruit juice, amino acid, vitamin, caffeine, taurine, etc. The second air pump 50 conveys gas into the storage container and carries the additives into the mixing bin 40 and mixes them into the bubble liquid. Different additives are mixed into the bubble liquid to obtain bubble liquids with different flavors.

[0112] In a preferred implementation manner of the embodiment of the present invention, as Figure 3 and Figure 5 shown, the liquid storage device 10 includes:

[0113] A first container 11, which is used for loading liquid;

[0114] A pump body 12, which is respectively communicated with the first container 11 and the liquid inlet 312.

[0115] Specifically, the first container 11 can hold a liquid. A filter 13 can also be arranged inside the first container 11. Then, solids can be added to the first container 11. For example, ice cubes. The added solids are blocked by the filter 13 inside the first container 11 and cannot enter the pump body 12. Of course, the ice cubes can melt and lower the temperature of the water. The low-temperature water is transported by the pump body 12 to the gas-liquid mixer 30, which is beneficial to increasing the concentration of carbon dioxide in the water.

[0116] In a preferred implementation manner of the embodiment of the present invention, as Figure 5 shown, the gas storage device 20 includes:

[0117] A second container 21 for loading carbon dioxide;

[0118] A gas slow-release component 22 communicating with the second container 21 and the air inlet.

[0119] Specifically, the second container 21 loads carbon dioxide. For example, it can be liquefied carbon dioxide. The gas slow-release component 22 reduces the pressure of the carbon dioxide released by the second container 21 and transports the carbon dioxide to the gas-liquid mixer 30.

[0120] Based on the bubble machine according to any one of the above embodiments, the present invention also provides a preferred embodiment of a control method for a bubble machine.

[0121] The control method for the bubble machine in the embodiment of the present invention includes the following steps:

[0122] Step S100: Transport a liquid into the gas-liquid mixer through a liquid storage device;

[0123] Step S200: Drive a rotating member to rotate through a stirring driving member to stir the liquid;

[0124] Step S300: Transport carbon dioxide into the gas-liquid mixer through a gas storage device;

[0125] Step S400: When the liquid and carbon dioxide are mixed to form a mixed liquid, control the drain valve to open to discharge the mixed liquid.

[0126] Specifically, when preparing the bubble liquid, first transport the liquid to the gas-liquid mixer through the liquid storage device, specifically control the start of the pump body, and extract the liquid in the first container to the gas-liquid mixer; when the second liquid level gauge detects the liquid, control the pump body to close and stop extracting the liquid in the first container. If the first liquid level gauge also detects the liquid, it indicates that the liquid is excessive and the drain valve needs to be started to drain the liquid in the gas-liquid mixer. If the first liquid level gauge does not detect the liquid and the second liquid level gauge detects the liquid, the subsequent steps can be carried out. Drive the rotating member to rotate through the stirring drive member, thereby stirring the liquid, and transport carbon dioxide to the gas-liquid mixer through the gas storage device, so that the carbon dioxide dissolves in the liquid. Specifically, release the carbon dioxide in the second container through the gas slow-release component and transport it to the gas-liquid mixing chamber. When the mixing of the liquid and carbon dioxide is completed, the drain valve can be controlled to open, thereby discharging the mixed liquid.

[0127] Before controlling the drain valve to open, the exhaust valve of the overpressure exhaust component can be controlled to discharge the gas in advance to reduce the air pressure to the atmospheric pressure or slightly greater than the atmospheric pressure. If the air pressure in the gas-liquid mixer drops to the atmospheric pressure, when the drain valve is opened, the liquid in the gas-liquid mixer will drain out from the outlet under the action of gravity. If the air pressure in the gas-liquid mixer drops to slightly greater than the atmospheric pressure, when the drain valve is opened, the liquid in the gas-liquid mixer will quickly drain out from the outlet under the action of gravity and air pressure. The blowing action of the first air pump can also be combined to further assist the liquid in the gas-liquid mixer to quickly drain out from the outlet.

[0128] During the process of discharging the mixed liquid, control the first air pump to open and control the second air pump to open, so that the mixed liquid and the additive are mixed. Specifically, controlling both the first air pump and the second air pump to open is beneficial to fully mixing the additive and the mixed liquid.

[0129] It should be understood that the application of the present invention is not limited to the above examples. For those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present invention.
