Description

Technical Field

[0001] This utility model relates to the field of beverage machine technology, and in particular to an aeration structure for a soda water machine. Background Technology

[0002] A soda maker is a device that fills water or beverages with carbon dioxide gas to make soda water and other carbonated drinks. It typically includes a gas cylinder, a water bottle, and a gas filling mechanism. The water bottle has a filling port at the bottom, and the gas cylinder connects to the water bottle through the filling port, filling the water bottle with carbon dioxide gas to mix with the water and produce soda water. During the soda water making process, the user can hear a "hissing" sound, which usually indicates that the filling is complete.

[0003] Chinese patent CN112568355A discloses a bottled component for soda water, comprising a base, a water bottle, an air inlet, an air inlet pipe, a pressure relief valve, a bottle cap cover, a bottle cap, and multiple sealing gaskets. The water bottle consists of a bottle bottom, a bottle body, and a connector. The bottom of the bottle body is inserted into the bottle bottom, and an air inlet is provided in the bottle bottom located at the bottom port of the bottle body. A connector is inserted in the bottle bottom below the air inlet. A conical hole is provided at the bottom of the connector, and an air inlet is inserted into the conical hole. The air outlet end of the air inlet pipe passes through a locking nut and is located in the air inlet end. The other end of the air inlet pipe is connected to a carbon dioxide gas cylinder in a soda water machine. A pressure relief valve is provided in the recessed structure of the bottle cap located at the upper port of the bottle body, and the upper end of the pressure relief valve is movably embedded in the bottle cap cover.

[0004] The problem with the existing technology is that after inflation, when the water bottle is removed from the base and the connector is disconnected from the air inlet, although the gas cylinder switch is closed, there is still some high-pressure gas inside the air inlet pipe, air inlet, and other connectors / pipes. This gas will be sprayed directly outward through the air inlet, potentially hitting the water bottle or the user's hands, posing a safety hazard. Therefore, the existing technology needs improvement and development. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a soda water machine inflation structure that is reasonable in structure, easy to operate, and safe and reliable.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The present invention discloses a soda maker inflation structure, comprising a base, on which a gas cylinder and an inflation assembly are mounted. The inflation assembly includes a valve and an inflation nozzle. The valve has several interfaces, through which the gas cylinder is connected to the inner cavity of the valve. A piston is located in the inner cavity of the valve, and the inflation nozzle is linked to the piston and connected to the inner cavity of the valve, thereby enabling the gas cylinder to be inflated through the inflation nozzle, or to be vented through the interfaces on the valve.

[0008] When the gas cylinder is being filled, the water bottle, after being paired with the filling nozzle, moves the piston. The piston switches the connection state of the valve, allowing gas from the gas cylinder to be injected into the water bottle through the valve and filling nozzle to make soda. After filling is complete, before the water bottle and filling nozzle separate, the piston first resets, and the piston switches the connection state of the valve, allowing any remaining high-pressure gas in the valve to be discharged through other ports, preventing the safety hazard of excess gas being ejected from the filling nozzle when the water bottle and filling nozzle separate.

[0009] According to the above scheme, several interfaces include an air inlet, an exhaust port, and a pressure relief port. The inner cavity of the valve forms an actuation chamber, which extends through the upper end of the valve to form an exhaust port. The lower end of the valve is provided with a pressure relief port that connects to the actuation chamber. The air inlet is located on the side wall of the valve and is connected to the gas cylinder through an air inlet pipe. The piston is movably disposed in the actuation chamber, and a first sealing ring that mates with the inner side wall of the valve is provided on the outer side wall of the piston.

[0010] The actuating chamber within the valve is vertically oriented, aligning with the direction in which the water bottle is inserted and removed. The inflation nozzle passes through the exhaust port and connects to the piston, enabling the piston to move vertically within the actuating chamber. The piston, through a first sealing ring, engages with the inner wall of the valve to separate the actuating chamber, thereby connecting the air inlet to the exhaust port or the pressure relief port.

[0011] Specifically, when the water bottle is placed on the base for inflation, the water bottle is paired with the inflation nozzle and drives the piston to approach the pressure relief port. At this time, the air inlet is connected to the inflation nozzle in the exhaust port through the actuation chamber. The high-pressure gas (carbon dioxide) in the gas cylinder is injected into the water bottle from the air inlet pipe, valve and inflation nozzle to form soda water.

[0012] After inflation is complete, the inflation nozzle drives the piston toward the exhaust port, so that the air inlet is connected to the pressure relief port through the actuation chamber. At this time, the remaining high-pressure gas in the air inlet pipe and valve can be discharged from the pressure relief port.

[0013] According to the above scheme, the base is provided with an inflation seat, the valve is fixedly connected to the inflation seat, and a third sealing ring is provided between the exhaust port and the inflation seat; a positioning post is provided on the bottom surface of the inflation seat, and the positioning post passes through the exhaust port so that the lower end of the positioning post is paired with the piston in the action chamber.

[0014] The inflation seat is used to control the installation position of the inflation assembly and the positioning of the water bottle during inflation. It is understood that the valve is sealed to the inflation seat via a third sealing ring on the vent, and the positioning post passes through the vent, ensuring that the valve and positioning post are concentrically positioned. The lower end of the positioning post is paired with a piston, thereby controlling the upward displacement distance of the piston. In short, the inflation seat and the third sealing ring constitute a sealing structure on the vent, allowing the valve's internal actuating chamber to be independently positioned and ensuring the upward movement stroke of the piston.

[0015] When the water bottle is placed on the inflation base for inflation, the water bottle is paired with the inflation nozzle and moves the piston, connecting the air inlet and the air outlet. At this time, the high-pressure gas (carbon dioxide) in the gas cylinder is injected into the water bottle from the air inlet pipe, valve and inflation nozzle to form soda water.

[0016] After inflation is complete, separating the water bottle from the inflation nozzle will cause the piston to approach the lower end of the positioning pin. At this time, the passage between the action chamber and the air inlet is cut off, so that excess gas will not be sprayed out from the inflation nozzle and cause injury.

[0017] According to the above scheme, the positioning post has a central through hole, and the inflation nozzle can be movably inserted through the central through hole. A second sealing ring is provided between the inflation nozzle and the positioning post. The upper end of the inflation nozzle extends out and is mounted on the inflation seat, and the lower end of the inflation nozzle is fixedly connected to the piston. The lower end of the inflation nozzle is provided with an air inlet. The central through hole on the positioning post is used to control the movement path of the inflation nozzle, ensuring stable cooperation between the piston and the valve in the action chamber. When the piston moves downward and approaches the pressure relief port, the air inlet, the action chamber, and the air inlet on the inflation nozzle are connected.

[0018] According to the above scheme, a spring is provided in the actuating chamber of the valve component, and a limiting seat is provided on the lower end face of the valve component. The limiting seat is paired with the piston. The lower end of the spring is assembled on the limiting seat, and the upper end of the spring abuts against the piston. The limiting seat is primarily used to assemble the spring to prevent spring misalignment from affecting piston reset. Simultaneously, the limiting seat is located on the lower end face of the valve component, and the pressure relief port is opposite to the limiting seat. When the piston moves downward and approaches the pressure relief port, the piston contacts the limiting seat to achieve limitation, and at this time, the passage between the air inlet and the pressure relief port is cut off.

[0019] According to the above scheme, the base has a main body, and the gas cylinder is detachably installed inside the main body. An inflation wrench is located at the upper end of the main body, and the inflation wrench is connected to the valve assembly on the gas cylinder. The main body is vertically mounted on the base, and the upper end of the main body has the valve assembly connecting to the gas cylinder. The inflation wrench is used to control the valve assembly. When the water bottle is paired with the inflation nozzle, pulling the inflation wrench opens the valve assembly. After inflation is complete, pulling the inflation wrench closes the valve assembly and shuts off the gas cylinder. At this time, the high-pressure gas remaining in the inlet pipe and valve components is discharged from the pressure relief port as the water bottle is disassembled and the piston resets.

[0020] According to the above scheme, this utility model also includes a water bottle. The lower end of the water bottle is provided with an inflation connector, and the inflation base is provided with a socket. The inflation connector has a self-sealing port. When the water bottle is connected to the socket through the inflation connector, the self-sealing port is paired with the inflation nozzle. The inflation connector and the socket are adapted to each other, allowing the self-sealing port and the inflation nozzle to be accurately paired. Of course, the inflation nozzle or the self-sealing port is provided with a sealing element. After the water bottle is installed on the inflation base, the inflation nozzle can be pushed downwards along the central through hole, simultaneously causing the piston to approach the limiting seat. After the piston can no longer move, the inflation nozzle completes the pairing with the self-sealing port, and gas can be injected into the water bottle through the self-sealing port. Of course, the inflation connector can be connected to the socket through a screw-on structure to prevent the water bottle from loosening during inflation. After inflation is complete, the water bottle is removed from the inflation base. At this time, the self-sealing port can automatically seal, preventing water and gas leakage from the water bottle.

[0021] According to the above scheme, the upper end of the water bottle is equipped with a pressure relief cap. It is understood that the pressure inside the water bottle after inflation is relatively large, and the cap of the water bottle is difficult to open. The pressure relief cap can release the pressure of the water bottle before opening, avoid the difficulty of opening the cap, and prevent the pressure inside the water bottle from blowing the cap off.

[0022] This utility model discloses a soda water machine inflation structure. During inflation, the water bottle is paired with the inflation nozzle, which drives the piston to move. The piston switches the connection state of the valve, allowing the gas in the gas cylinder to be injected into the water bottle through the valve and inflation nozzle to make soda water. After inflation is completed, the separation of the water bottle and the inflation nozzle will first drive the piston to reset, allowing the high-pressure gas remaining in the valve to be discharged from other interfaces, avoiding the safety hazard of excess gas being sprayed out of the inflation nozzle when the water bottle and the inflation nozzle are separated.

[0028] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-3 As shown, the present invention discloses a soda water machine inflation structure, including a base 1, on which a gas cylinder 11 and an inflation assembly are provided. The inflation assembly includes a valve 3 and an inflation nozzle 2. The valve 3 is provided with several interfaces, through which the gas cylinder 11 is connected to the inner cavity of the valve 3. A piston 34 is provided in the inner cavity of the valve 3. The inflation nozzle 2 is linked with the piston 34 and connected to the inner cavity of the valve 3, thereby enabling the gas cylinder 11 to be inflated through the inflation nozzle 2, or enabling the gas cylinder 11 to be vented through the interfaces on the valve 3.

[0030] When the gas cylinder 11 is being inflated, the water bottle 4, after being paired with the inflation nozzle 2, moves the piston 34. The piston 34 switches the connection state of the valve 3, allowing the gas in the gas cylinder 11 to be injected into the water bottle 4 through the valve 3 and the inflation nozzle 2 to make soda water. After inflation is complete, before the water bottle 4 separates from the inflation nozzle 2, the piston 34 will first return to its original position. The piston 34 then switches the connection state of the valve 3, allowing any remaining high-pressure gas in the valve 3 to be discharged through other ports, thus preventing the safety hazard of excess gas being ejected from the inflation nozzle 2 when the water bottle 4 separates from the inflation nozzle 2.

[0031] Several interfaces include an air inlet 31, an exhaust port 32, and a pressure relief port 33. The inner cavity of the valve 3 forms an actuation chamber 300. The actuation chamber 300 passes through the upper end of the valve 3 to form an exhaust port 32. The lower end of the valve 3 is provided with a pressure relief port 33 that communicates with the actuation chamber 300. The air inlet 31 is located on the side wall of the valve 3 and is connected to the gas cylinder 11 through an air inlet pipe 12. The piston 34 is movably disposed in the actuation chamber 300, and the outer side wall of the piston 34 is provided with a first sealing ring 35 that mates with the inner side wall of the valve 3.

[0032] The actuating chamber 300 inside the valve 3 is arranged vertically, in the same direction as the water bottle 4 being inserted and removed. The inflation nozzle 2 passes through the exhaust port 32 and is connected to the piston 34, which can drive the piston 34 to move vertically within the actuating chamber 300. The piston 34 cooperates with the inner wall of the valve 3 through the first sealing ring 35 (commonly known as the piston ring) to separate the actuating chamber 300, thereby connecting the air inlet 31 to the exhaust port 32 or the pressure relief port 33.

[0033] Specifically, when the water bottle 4 is placed on the base 1 for inflation, the water bottle 4 is paired with the inflation nozzle 2 and drives the piston 34 to approach the pressure relief port 33. At this time, the air inlet 31 is connected to the inflation nozzle 2 in the exhaust port 32 through the action chamber 300. The high-pressure gas (carbon dioxide) in the gas cylinder 11 is injected into the water bottle 4 from the air inlet pipe 12, valve 3 and inflation nozzle 2 to form soda water.

[0034] After inflation is complete, the inflation nozzle 2 drives the piston 34 toward the exhaust port 32, so that the air inlet 31 is connected to the pressure relief port 33 through the action chamber 300. At this time, the remaining high-pressure gas in the air inlet pipe 12 and valve 3 can be discharged from the pressure relief port 33.

[0035] The base 1 is provided with an inflation seat 2, the valve 3 is fixedly connected to the inflation seat 2, and a third sealing ring 36 is provided between the exhaust port 32 and the inflation seat 2; the bottom surface of the inflation seat 2 is provided with a positioning post 22, which passes through the exhaust port 32 so that the lower end of the positioning post 22 is paired with the piston 34 in the action chamber 300.

[0036] The inflation seat 2 is used to control the installation position of the inflation assembly and the positioning of the water bottle 4 during inflation. It is understood that the valve 3 is sealed to the inflation seat 2 via the third sealing ring 36 on the vent 32, and the positioning post 22 passes through the vent 32, making the valve 3 and the positioning post 22 concentrically positioned. The lower end of the positioning post 22 is paired with the piston 34, thereby controlling the upward displacement distance of the piston 34. In short, the inflation seat 2 and the third sealing ring 36 constitute a sealing structure on the vent 32, allowing the actuating chamber 300 within the valve 3 to be independently positioned and ensuring the upward movement stroke of the piston 34.

[0037] When the water bottle 4 is placed on the inflation seat 2 for inflation, the water bottle 4 is paired with the inflation nozzle 2 and drives the piston 34 to move, so that the air inlet 31 is connected to the exhaust port 32. At this time, the high-pressure gas (carbon dioxide) in the gas cylinder 11 is injected into the water bottle 4 from the air inlet pipe 12, valve 3 and inflation nozzle 2 to form soda water.

[0038] After inflation is complete, the action of separating the water bottle 4 from the inflation nozzle 2 will cause the piston 34 to approach the lower end of the positioning post 22. At this time, the passage between the action chamber 300 and the air inlet 25 is cut off, so that excess gas will not be sprayed out from the inflation nozzle 2 and cause injury.

[0039] The positioning post 22 has a central through hole 23, through which the inflation nozzle 2 can move vertically. A second sealing ring is provided between the inflation nozzle 2 and the positioning post 22. The upper end of the inflation nozzle 2 extends out onto the inflation seat 2, and the lower end of the inflation nozzle 2 is fixedly connected to the piston 34. The lower end of the inflation nozzle 2 has an air inlet 25. The central through hole 23 on the positioning post 22 is used to control the movement path of the inflation nozzle 2, ensuring that the piston 34 and the valve 3 cooperate stably within the action chamber 300. When the piston 34 moves downward and approaches the pressure relief port 33, the air inlet 31, the action chamber 300, and the air inlet 25 on the inflation nozzle 2 are connected.

[0040] A spring 37 is provided inside the actuating chamber 300 of the valve component 3, and a limiting seat 38 is provided on the lower end face of the valve component 3. The limiting seat 38 is paired with the piston 34. The lower end of the spring 37 is mounted on the limiting seat 38, and the upper end of the spring 37 abuts against the piston 34. The limiting seat 38 is primarily used to mount the spring 37 to prevent the spring 37 from shifting and affecting the piston 34's reset. Simultaneously, the limiting seat 38 is located on the lower end face of the valve component 3, and the pressure relief port 33 is positioned opposite the limiting seat 38. When the piston 34 moves downward and approaches the pressure relief port 33, the piston 34 contacts the limiting seat 38 to achieve a limit, and at this time, the passage between the air intake port 31 and the pressure relief port 33 is cut off.

[0041] The base 1 has a main body 13, and the gas cylinder 11 is detachably installed inside the main body 13. An inflation wrench 14 is located at the upper end of the main body 13, and the inflation wrench 14 is connected to the valve assembly on the gas cylinder 11. The main body 13 is vertically mounted on the base 1, and the upper end of the main body 13 has a valve assembly connected to the gas cylinder 11. The inflation wrench 14 controls the valve assembly. When the water bottle 4 is paired with the inflation nozzle 21, pulling the inflation wrench 14 opens the valve assembly. After inflation is complete, pulling the inflation wrench 14 closes the valve assembly, shutting off the gas cylinder 11. At this time, the high-pressure gas remaining in the air inlet pipe 12 and valve 3 is discharged from the pressure relief port 33 as the water bottle 4 is disassembled and the piston 34 is reset.

[0042] This utility model also includes a water bottle 4, the lower end of which is provided with an inflation connector 41, and the inflation base 2 is provided with a socket 26. The inflation connector 41 is provided with a self-sealing port 42. When the water bottle 4 is connected to the socket 26 through the inflation connector 41, the self-sealing port 42 is paired with the inflation nozzle 21. The inflation connector 41 and the socket 26 are adapted to accurately pair the self-sealing port 42 with the inflation nozzle 21. Of course, the inflation nozzle 21 or the self-sealing port 42 is provided with a sealing element. After the water bottle 4 is installed on the inflation base 2, the inflation nozzle 21 can be pushed to move downward along the central through hole 23, and at the same time, the piston 34 is driven to approach the limiting seat 38. After the piston 34 can no longer move, the inflation nozzle 21 completes the pairing with the self-sealing port 42, and gas can be filled into the water bottle 4 through the self-sealing port 42. Of course, the inflation connector 41 can be connected to the socket 26 through a screw-on structure to prevent the water bottle 4 from loosening during inflation. After inflation is complete, remove the water bottle 4 from the inflation base 2. At this time, the self-sealing port 42 can automatically seal to prevent water and gas leakage from the water bottle 4.

[0043] The upper end of the water bottle 4 is provided with a pressure relief cap 43. It is understood that the pressure inside the water bottle 4 after inflation is relatively large, and the cap of the water bottle 4 is difficult to open. The pressure relief cap 43 can release the pressure of the water bottle 4 before opening the cap, so as to avoid difficulty in opening the cap and prevent the pressure inside the water bottle 4 from blowing the cap off.

[0044] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
