Description

Technical Field

[0001] This invention relates to the field of soft drink preparation technology, and more specifically to a soft drink manufacturing machine. Background Technology

[0002] The basic structure of existing sparkling water machines includes a machine head with an interface slot, an air pumping pipe inside the interface slot, and a controllable air pumping valve on the air pumping pipe to control the air release from the cylinder. The interface slot is also connected to the outside through a pipe, and a control valve is also installed on this pipe to control the pressure release inside the beverage bottle.

[0003] After the interface groove is threadedly connected to the bottle neck, a sealed space is formed inside the beverage bottle. After the beverage bottle is installed, the bottom end of the air pump is below the liquid surface. The valve is operated to allow the exhaust pipe to vent air into the liquid and create positive pressure above the liquid surface. When the pressure is sufficient, the exhaust is opened to release excess gas, preventing explosion or preventing liquid from spraying out after the beverage bottle is removed.

[0004] Because the types of beverages to be carbonated are frequently changed, the lower outer part of the carbonation tube needs to be wiped after each beverage is made to prevent flavor mixing. This is inconvenient, and the excess carbon dioxide on the liquid surface being released to the outside also causes waste. Summary of the Invention

[0005] To address the problems existing in the above-mentioned technologies, the present invention provides a soft drink manufacturing machine, comprising an interface groove for docking with the mouth of a beverage bottle, an air pumping pipe disposed within the interface groove, the air pumping pipe being connected to a gas cylinder via a pipeline and having an air pumping valve disposed on the pipeline, and an expandable and contractible elastic container, the elastic container being connected to the interior of the interface groove via an air inlet pipeline, the air inlet pipeline being provided with a one-way valve and a first pressure relief valve, the first pressure relief valve opening when the gas pressure inside the beverage bottle reaches a preset value; and an air jet point, the air jet point being directed towards the end of the air pumping pipe, the air jet point being connected to the elastic container via an exhaust pipeline, and a control valve disposed on the exhaust pipeline.

[0006] The elastic container includes a gas-containing tube, a gas-containing piston is disposed inside the gas-containing tube, an elastic element is disposed on one side of the gas-containing piston, and the air inlet pipe and the air outlet pipe are located on the other side of the gas-containing piston.

[0007] It also includes a second pressure relief valve that is connected to the outside. The second pressure relief valve is connected to the inside of the interface groove through a pipeline. When the elastic container stops expanding, the second pressure relief valve opens.

[0008] The second pressure relief valve includes a second piston tube, which is parallel to the gas-bearing tube. A second piston is disposed inside the second piston tube. The second piston tube has an open end and a second exhaust port is disposed on the side wall of the second piston tube. A U-shaped connecting rod is disposed on one side of the second piston. The connecting rod extends out from the open end of the second piston tube and the protruding end of the connecting rod is connected to the gas-bearing piston.

[0009] The first pressure relief valve includes a vertically arranged first piston tube, the bottom of which is connected to the interior of the interface groove. A first piston is disposed inside the first piston tube, and a first exhaust port connected to the air intake pipe is disposed on the side wall of the first piston tube. When the first piston moves to the top, the first exhaust port is exposed.

[0010] The first piston tube has a groove on its inner sidewall, which is located above the first exhaust port. An elastic bending member is disposed in the groove. A slot is disposed on the sidewall of the first piston. When the first piston moves to the top, the slot corresponds to the position of the elastic bending member. The elastic bending member pops out of the groove and extends into the slot. A return mechanism is also provided to move the elastic bending member back into the groove.

[0011] The control valve includes a sealed cavity and a horizontally arranged control pipe, both of which are connected to the exhaust pipe.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1 to 4 As shown, an embodiment of a soft drink making machine includes an interface groove 9 for docking with the bottle neck of a beverage bottle 6, which can be connected by a thread. An air pumping pipe 1 is set in the interface groove 9. The air pumping pipe 1 is connected to a gas cylinder (not shown) through a pipeline and an air pumping valve (not shown) is set on the pipeline. The above part is the same as the prior art.

[0022] The inventive points of this application are as follows:

[0023] It also includes an expandable and contractible elastic container 2. The elastic container 2 is connected to the inside of the interface groove 9 through the air inlet pipe 24. A one-way air valve 35 and a first pressure relief valve 3 are provided on the air inlet pipe 24. The first pressure relief valve 3 opens after the air pressure inside the beverage bottle 6 reaches the preset value.

[0024] The jet point is located at the end of the air pump pipe. Specifically, the jet point can be the bottom end of the sleeve 11. The sleeve 11 is fitted on the outside of the air pump pipe 1 and its length is slightly shorter. The sleeve 11 is connected to the elastic container 2 through the exhaust pipe 25. A control valve 5 is installed on the exhaust pipe 25.

[0025] The elastic container 2 includes a gas-containing tube 22, a gas-containing piston 21 is disposed inside the gas-containing tube 22, a spring (not shown) is disposed on one side of the gas-containing piston 21 and is equipped with a sealing ring 10, and an air inlet pipe 24 and an exhaust pipe 25 are located on the other side of the gas-containing piston 21.

[0026] It also includes a second pressure relief valve 4 that is connected to the outside (located outside the beverage bottle 6 after installation). The second pressure relief valve 4 includes a second piston tube 41, which is parallel to the gas-containing tube 22. A second piston 42 is provided inside the second piston tube 41. The second piston 42 is equipped with a sealing ring 10. The second piston tube 41 has an open end. A second exhaust port 43 is provided on the side wall of the second piston tube 41. The second exhaust port 43 is connected to the outside.

[0027] A U-shaped connecting rod 23 is provided on one side of the second piston 42. The connecting rod 23 extends out from the open end of the second piston tube 41 and the protruding end of the connecting rod 23 is connected to the gas-bearing piston 21, so that the two pistons can move synchronously.

[0028] The second pressure relief valve 4 is connected to the inside of the interface groove 9 through a pipeline. When the elastic container 2 stops expanding, the second pressure relief valve 4 opens, so that the inside of the interface groove 9 is connected to the outside.

[0029] like Figure 3 As shown, the first pressure relief valve 3 includes a vertically arranged first piston tube 31, the bottom of the first piston tube 31 is connected to the inside of the interface groove 9, a columnar first piston 32 is arranged inside the first piston tube 31, and a first exhaust port 33 connected to the intake pipe 24 is arranged on the side wall of the first piston tube 31.

[0030] When the beverage bottle 6 is filled with gas, the pressure causes the first piston 32 to move to the top, exposing the first exhaust port 33 and inflating the elastic container 2.

[0031] A spring can also be installed on the top of the first piston 32 to control the exhaust pressure. When the gas pressure in the beverage bottle 6 exceeds the sum of the spring force and the weight of the first piston 32, i.e., the preset value, exhaust will then be performed.

[0032] Meanwhile, a groove 341 is provided on the inner wall of the first piston tube 31. The groove 341 is located above the first exhaust port 33. An elastic bending member 34 is provided in the groove 341. The elastic bending member 34 can be an arc-shaped elastic metal sheet with its top bent toward the middle of the first piston tube 31. A sealing ring 10 is provided at the lower part of the first piston 31.

[0033] A slot 321 is provided on the side wall of the first piston 32, preferably an annular slot. When the first piston 32 moves to the top, the slot 321 corresponds to the position of the elastic bending member 34. The elastic bending member 34 pops out from the groove 341 and extends into the slot 321.

[0034] Specifically, the elastic bending member 34 can be moved back into the groove 341 by the return mechanism.

[0035] like Figure 3 As shown, the control valve 5 includes a sealing cavity 51 and a horizontally arranged control pipe 52. Both the sealing cavity 51 and the control pipe 52 are connected to the exhaust pipe 25.

[0036] One end of the control tube 52 is connected to the sealing cavity 31. A conical valve 511 that mates with the control tube 52 is installed inside the sealing cavity 31. A pull rod 71 is installed on the conical valve 511 and passes through it coaxially. The two ends of the pull rod 71 pass through one end of the control tube 52 and the side wall of the sealing cavity 51, respectively. A spring (not shown) is installed inside the control tube 52. One end of the spring is connected to the conical valve 511, and the other end of the spring is connected to the inner side wall of the end of the control tube 52 away from the sealing cavity 51. The pull rod 71 is slidably and sealingly connected to the side wall of the sealing cavity 51 and one end of the control tube 52 through the sealing ring 10.

[0037] A through hole (not shown) is provided at the bottom of the groove 341. The pull-back mechanism is a pull rope 8. One end of the pull rope 8 is connected to the end of the pull rod 7 away from the sealing cavity 51, and the other end of the pull rope 8 passes through the through hole of the groove 341 and is connected to the movable end of the elastic bending member 34.

[0038] The working principle of this application is as follows:

[0039] 1. Connect the beverage bottle 6 to the interface groove 9 with a threaded seal. Inflate the beverage bottle 6 with air through the air pumping pipe 1 to the area below the liquid surface. As the pressure increases, the first piston 32 is lifted. After being lifted, the slot 321 and the elastic bending member 34 are aligned. The upper part of the elastic bending member 34 is inserted into the slot 321, keeping the first piston 32 in this position. Excess gas in the beverage bottle 6 enters the gas-containing pipe 22 through the first exhaust port 33 and the air inlet pipe 24. The gas pressure pushes the gas-containing piston 21 to move until the gas-containing piston 21 moves to the rightmost end. At the same time, the second piston 42 moves to the rightmost end, opening the second exhaust port 43, allowing the remaining gas in the beverage bottle 6 to be discharged, so that the air pressure inside and outside the beverage bottle 6 is consistent.

[0040] During this process, once the first exhaust 33 is heard to exhaust, the air pumping pipe 1 should be stopped. The first piston rod 32 is designed to automatically exhaust the gas after the pressure inside the bottle reaches the preset value. During exhaust, the elastic container 2 absorbs some gas first, and then the gas is discharged through the second exhaust port 43, achieving the effect of slow exhaust in stages, preventing the concentrated beverage liquid from forming too many bubbles during decompression.

[0041] 2. After the second exhaust port 43 has finished venting, remove the beverage bottle 6 to obtain the soft drink.

[0042] 3. Pull the pull ring 7 outward, the conical valve 511 moves outward, and the control valve 5 is opened. The gas in the elastic container 2 enters the sleeve 11 through the sealing cavity 51 of the control valve 5 and the control tube 5, and passes through the guide jet of the sleeve 11 to blow away most of the liquid remaining on the bottom outer wall of the air blowing pipe 1, thus completing the cleaning and preventing cross-contamination of flavors when making different soft drinks next time.

[0043] At the same time, due to the spring corresponding to the gas valve 21 returning to its original position, the gas valve 21 and the driven second piston 42 return to their original positions, closing the second exhaust port 43.

[0044] 4. While pulling the pull ring 7, the elastic bending member 34 is pulled back into the groove 341 by the pull rope 8. Without the obstruction of the elastic bending member 34, the first piston 32 moves downward back to its original position under the action of the corresponding spring and gravity, closing the first pressure relief valve 3. At this time, the elastic bending member 34 abuts against the upper part of the side wall of the first piston 32.

[0045] 5. Loosen the pull ring 7, and the spring corresponding to the conical valve 511 will return to its original position, closing the control valve 5 to complete one operation.

[0046] All sealing rings 10 used in this application can be lip-type sealing rings.

[0047] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
