DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Please also see Figure 1-Figure 12 , the present invention provides some embodiments of a bubble machine.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the bubble machine of the present invention comprises: a liquid storage tank 10, a gas storage tank 20 and a gas-liquid mixer 30; the liquid storage tank 10 is used to store liquid, and the gas storage tank 20 is used to store carbon dioxide.

[0033] Specifically, the liquid reservoir 10 stores liquid, and the liquid may be water. Figure 2 and Figure 3As shown, a filter 13 is provided in the liquid reservoir 10, and 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. Ice cubes can lower the temperature of the liquid to a preset temperature range, which is beneficial to increase 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. The liquid reservoir 10 and the gas reservoir 20 are both connected to the gas-liquid mixer 30, and the liquid reservoir 10 injects the liquid into the gas-liquid mixer 30, and then the gas reservoir 20 injects the carbon dioxide gas into the gas-liquid mixer 30. Since the pressure of the carbon dioxide gas is greater than the atmospheric pressure when the carbon dioxide gas is injected into the gas-liquid mixer 30, the solubility of the carbon dioxide gas in the liquid is higher.

[0034] like Figure 5 , Figure 6 and Fig. 9 As shown, the gas-liquid mixer 30 comprises: The housing 31 has a bottom structure 31a which forms a first air inlet 311, a liquid inlet 312 and an outlet 313, wherein the first air inlet 311 is in communication with the air reservoir 20, the liquid inlet 312 is in communication with the liquid reservoir 10, and the outlet 313 is provided with a drain valve 3131; the top structure 31b of the housing 31 is a spherical crown top structure; The rotating member 32 has two ends which are rotatably connected to the bottom structure 31a of the shell 31 and the top structure 31b of the shell 31 respectively; A stirring driving member 33 is disposed outside the housing 31 and is used to drive the rotating member 32 to rotate; A plurality of arc-shaped frames 34, disposed on the rotating member 32; The plurality of arc frames 34 form a spherical crown structure.

[0035] Specifically, the shell 31 is used to contain liquid and carbon dioxide gas. The carbon dioxide gas enters the interior of the shell 31 from the first air inlet 311, and the liquid enters the interior of the shell 31 from the liquid inlet 312. After carbon dioxide is dissolved into the solution, bubble liquid is formed, and the bubble liquid flows out from the outlet 313. When the drain valve 3131 is opened, the bubble liquid flows out from the outlet 313. The shell 31 is divided into two parts, namely the bottom structure 31a and the top structure 31b. The first air inlet 311 is set at the bottom structure 31a, and the carbon dioxide entering the shell 31 from the first air inlet 311 will first contact the liquid in the bottom structure 31a, thereby increasing the contact probability between carbon dioxide and liquid. The top structure 31b of the shell 31 is a spherical crown top structure. When the rotating member 32 drives the liquid to rotate, the liquid forms a circulation. The flow direction of the circulating liquid is that the middle liquid sinks, the surrounding liquid floats, the lower liquid spreads outward, and the upper liquid concentrates inward, and finally presents a shape that is high around and low in the middle. The use of a spherical crown top structure is conducive to the rapid concentration of the upper liquid to the middle, accelerates the circulation flow of the liquid, and further increases the contact probability of carbon dioxide and liquid. Of course, when the rotation speed of the rotating member 32 is high, the surrounding liquid may reach the highest point of the spherical crown top structure, and the liquid is mainly located near the inner wall of the shell 31, and the position near the center of the shell 31 forms a state where gas and liquid blend with each other.

[0036] The arc frame 34 is used as the stirring structure, and multiple arc frames 34 form a spherical crown structure. The spherical crown structure is located at the center of the spherical crown top structure, and the ratio of the radius of the spherical crown structure to the radius of the spherical crown top structure is 1 / 3 to 2 / 3. The stirring driving member 33 drives the rotating member 32 and the arc frame 34 to rotate, thereby driving the liquid to form a high surrounding and low middle shape, and the arc frame 34 can span the liquid phase and the gas phase, which is easier to overcome the surface tension of the liquid, stir and break the liquid surface, and the liquid can enter the gas phase to form droplets, and the gas can enter the liquid phase to form bubbles, which is conducive to carbon dioxide contacting and dissolving in the liquid.

[0037] The present application accelerates the circulation flow of the liquid and promotes the mutual blending of the liquid phase and the gas phase through the coordination of the spherical crown top structure and the spherical crown structure, thereby increasing the possibility of carbon dioxide contacting and dissolving in the liquid, thereby increasing the concentration of carbon dioxide in the liquid.

[0038] In a preferred implementation of the embodiment of the present invention, Figure 6 As shown, the top structure 31 b of the housing 31 is provided with a first liquid level gauge 314 and a second liquid level gauge 315 .

[0039] Specifically, the amount of liquid cannot be too much. If there is too much liquid, there will be less space for gas in the shell 31, which may cause excessive air pressure. The amount of liquid cannot be too little. If there is too little liquid, the carbon dioxide in the liquid will easily reach saturation, which is not enough to dissolve an appropriate amount of carbon dioxide. The top structure 31b of the shell 31 is provided with two liquid level gauges, namely the first liquid level gauge 314 and the second liquid level gauge 315. The amount of injected liquid is determined by the liquid level gauge, and the amount of liquid is detected when the stirring drive 33 is not started. The height of the first liquid level gauge 314 is different from the height of the second liquid level gauge 315. For example, the height of the first liquid level gauge 314 is higher than the height of the second liquid level gauge 315. If the liquid level is lower than the position of the second liquid level gauge 315, the second liquid level gauge 315 does not detect liquid, and liquid needs to be replenished. If the liquid level is higher than the position of the first liquid level gauge 314, the first liquid level gauge 314 and the second liquid level gauge 315 both detect liquid, and excess liquid needs to be discharged. If the first liquid level gauge 314 does not detect liquid and the second liquid level gauge 315 detects liquid, and the liquid level is between the first liquid level gauge 314 and the second liquid level gauge 315 , the amount of liquid is appropriate.

[0040] In a preferred implementation of the embodiment of the present invention, Figure 9-11 As shown, the arc frame 34 includes: The extension portion 341 is extended along the radial direction of the rotating member 32; an arc-shaped portion 342 , wherein the upper end of the arc-shaped portion 342 is connected to the rotating member 32 , and the lower end of the arc-shaped portion 342 is connected to the extending portion 341 ; The first liquid level gauge 314 is higher than the upper end of the arc-shaped portion 342 ; the second liquid level gauge 315 is located between the upper end of the arc-shaped portion 342 and the lower end of the arc-shaped portion 342 .

[0041] 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 member 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 located between the upper end of the arc part 342 and the lower end of the arc part 342. During the rotation of the arc 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 frame 34 can be connected to each other, thereby improving the strength of the spherical crown structure.

[0042] In a preferred implementation of the embodiment of the present invention, Figure 5-Figure 6 As 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 .

[0043] 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.

[0044] In a preferred implementation of the embodiment of the present invention, Figure 6-Figure 8 As shown, the second air inlet 316 is also connected to an overpressure exhaust component 318 .

[0045] 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.

[0046] 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: 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.

[0047] 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.

[0048] In a preferred implementation of the embodiment of the present invention, Figure 9-11 As shown, the rotating member 32 includes: The rotating seat 321 rotates relative to the bottom structure 31a of the housing 31; The first magnet 322 is located in the rotating seat 321; The rotating shaft 323 is engaged with the rotating seat 321; The arc frame 34 is disposed on the rotating shaft 323 .

[0049] Specifically, the rotating seat 321 can rotate relative to the bottom structure 31a of the housing 31, a first magnet 322 is arranged in the rotating seat 321, and the rotating shaft 323 is detachably connected to the rotating seat 321. A through hole 3211 is formed in the center of the rotating seat 321, the rotating shaft 323 is a hollow shaft, and the shaft hole of the rotating shaft 323 is connected to the through hole 3211. The rotating seat 321 is disc-shaped.

[0050] In a preferred implementation of the embodiment of the present invention, Fig. 9 and Fig.11 As shown, the stirring driving member 33 includes: Motor 331; A rotating disk 332 connected to the output shaft of the motor 331; The second magnet 333 is located inside the rotating disk 332; The rotating disk 332 is located at a corresponding position of the rotating base 321 .

[0051] Specifically, the motor 331 drives the rotating disk 332 and the second magnet 333 to rotate, and drives the first magnet 322, the rotating seat 321 and the rotating shaft 323 to rotate together. The rotating disk 332 and the rotating seat 321 are not in contact, and this non-contact method makes the housing 31 less likely to leak.

[0052] like Fig. 9 and Fig.12 As shown, the through hole 3211 is provided with a shaft portion 3212, and the bottom structure 31a of the housing 31 includes: The peripheral portion 31a1 is formed with a central hole 31a3; The boss portion 31a2 is sealed and connected to the center hole 31a3; A limiting groove 31a4 is formed on the upper surface of the boss portion 31a2, and the shaft portion 3212 rotates in the limiting groove 31a4.

[0053] Specifically, a gap is formed between the boss portion 31a2 and the rotating seat 321, and the rotating disk 332 is inserted into the boss portion 31a2. The rotating seat 321 and the rotating disk 332 are respectively located on the inner and outer sides of the boss portion 31a2. When the rotating seat 321 rotates, the water in the gap is dispersed to the surroundings, and the air in the shaft hole of the rotating shaft 323 and the through hole 3211 is filled into the limiting groove 31a4, which is conducive to reducing the resistance of the shaft portion 3212 to rotation. The rotating disk 332 is provided with an avoidance groove 3321, which is located at the corresponding position of the limiting groove 31a4 to avoid the sinking limiting groove 31a4. The boss portion 31a2 can be made of metal material, which is conducive to improving the wear resistance of the boss portion 31a2. The shaft portion 3212 is not easy to wear in the limiting groove 31a4, and it is also convenient to replace the boss portion 31a2.

[0054] In a preferred implementation of the embodiment of the present invention, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the bubble machine also includes: The mixing chamber 40 is connected to the drain valve 3131; At least one storage container, disposed in the mixing bin 40; at least one second air pump 50, the second air pump 50 being in communication with a corresponding accumulator; Wherein, the material storage container is used to store the additive material.

[0055] Specifically, the mixing chamber 40 has a chamber opening, and other additives can be mixed in after the bubble liquid is prepared. Specifically, the bubble liquid and the additives are injected into the mixing chamber 40, mixed in the mixing chamber 40, and flow out from the chamber opening. The additives can be syrup, electrolyte solution, fruit juice, amino acids, vitamins, caffeine, taurine, etc. The second air pump 50 transports gas to the storage container and carries the additives into the mixing chamber 40, and mixes them into the bubble liquid. By mixing different additives into the bubble liquid, bubble liquids of different flavors can be obtained.

[0056] In a preferred implementation of the embodiment of the present invention, Figure 3 and Figure 5 As shown, the liquid reservoir 10 comprises: A first container 11, used for loading liquid; The pump body 12 is communicated with the first container 11 and the liquid inlet 312 respectively.

[0057] Specifically, the first container 11 can contain liquid, and a filter 13 can be configured in the first container 11, and solids, such as ice cubes, can be added to the first container 11. The added solids are blocked in the first container 11 by the filter 13 and cannot enter the pump body 12. Of course, the ice cubes can melt and reduce the temperature of the water, and the low-temperature water is transported to the gas-liquid mixer 30 by the pump body 12, which is conducive to increasing the concentration of carbon dioxide in the water.

[0058] In a preferred implementation of the embodiment of the present invention, Figure 5 As shown, the gas storage device 20 comprises: A second container 21, used for loading carbon dioxide; The gas slow-release component 22 is communicated with the second container 21 and the gas inlet.

[0059] Specifically, the second container 21 is loaded with carbon dioxide, for example, liquefied carbon dioxide. The gas slow-release component 22 reduces the pressure of the carbon dioxide released from the second container 21 and delivers the carbon dioxide to the gas-liquid mixer 30 .

[0060] Based on the bubble machine described in any of the above embodiments, the present invention also provides a preferred embodiment of a control method of the bubble machine.

[0061] The control method of the bubble machine according to the embodiment of the present invention comprises the following steps: Step S100, transporting liquid into the gas-liquid mixer through the liquid storage device; Step S200, driving the rotating member to rotate by the stirring driving member to stir the liquid; Step S300, transporting carbon dioxide into the gas-liquid mixer through the gas storage device; Step S400: After the liquid and carbon dioxide are mixed to form a mixed liquid, the drain valve is controlled to open to discharge the mixed liquid.

[0062] Specifically, when preparing the bubble liquid, firstly, liquid is transported to the gas-liquid mixer through the liquid reservoir, and then the pump body is controlled to start, and the liquid in the first container is extracted into the gas-liquid mixer; when the second liquid level gauge detects the liquid, the pump body is controlled to close, and the extraction of the liquid in the first container is stopped. If the first liquid level gauge also detects the liquid, it indicates that there is an excess of liquid, and the drain valve needs to be started to discharge 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 performed. The rotating member is driven to rotate by the stirring drive member, thereby stirring the liquid, and carbon dioxide is transported to the gas-liquid mixer through the gas reservoir, so that the carbon dioxide is dissolved in the liquid. Specifically, the carbon dioxide in the second container is released by the gas slow-release component and transported to the gas-liquid mixing chamber. When the liquid and carbon dioxide are mixed, the drain valve can be controlled to open to discharge the mixed liquid.

[0063] Before controlling the drain valve to open, the exhaust valve of the overpressure exhaust assembly can be controlled to exhaust gas in advance, reducing the air pressure to atmospheric pressure or slightly above atmospheric pressure. If the air pressure in the gas-liquid mixer is reduced to atmospheric pressure, when the drain valve is opened, the liquid in the gas-liquid mixer is discharged from the outlet under the action of gravity. If the air pressure in the gas-liquid mixer is reduced to slightly above atmospheric pressure, when the drain valve is opened, the liquid in the gas-liquid mixer is quickly discharged from the outlet under the action of gravity and air pressure. It can also be combined with the blowing effect of the first air pump to further assist the liquid in the gas-liquid mixer to be quickly discharged from the outlet.

[0064] In the process of discharging the mixed liquid, the first air pump is controlled to be turned on and the second air pump is controlled to be turned on so that the mixed liquid and the additive are mixed. Specifically, the first air pump and the second air pump are controlled to be turned on, which is conducive to fully mixing the additive and the mixed liquid.

[0065] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
