An exhaust valve structure for a sparkling water machine

Abstract

This utility model discloses an exhaust valve structure for a sparkling water machine, including an air passage body, an operating chamber and an exhaust chamber arranged on the air passage body, an exhaust valve, an exhaust valve rod, a first return spring, a second return spring, and an air guide pipe. During normal operation, the first return spring controls the operating valve rod to be located at the end of the operating chamber near the operating hole, and the driving valve section extends to its maximum distance outside the air passage body. At this time, the operating valve section does not contact the exhaust valve, and the exhaust valve completely seals the first connecting hole between the exhaust chamber and the operating chamber. When exhaust is required, a driving component arranged inside the sparkling water machine cooperates with the driving valve section and presses the driving valve section, causing the driving valve section to push the exhaust valve to move within the exhaust chamber. This allows the air intake channel to connect unobstructed with the exhaust hole in the exhaust chamber through the first connecting hole, thereby guiding the carbon dioxide gas in the sparkling water bottle to a specific area along the air guide pipe, thus preventing the moisture in the emitted carbon dioxide gas from corroding the parts.

Description

Technical Field

[0001] This utility model relates to the field of sparkling water machines, and in particular to an exhaust valve structure for a sparkling water machine. Background Technology

[0002] A sparkling water machine is a device used to prepare sparkling water. Referring to the press-type exhaust and intake sparkling water machine disclosed in patent number 202221536844.4, the traditional exhaust structure of a sparkling water machine is to set a valve chamber on the main body of the air passage, and set a valve head on the valve chamber. One end of the valve head extends to the outside of the main body of the air passage, and the gap between the valve head and the valve chamber is used for exhaust. The active exhaust is controlled by setting a component on the outside of the main body of the air passage to control the movement distance of the valve head. However, this method has a drawback, that is, the exhaust gas is directly discharged into the entire sparkling water machine, and cannot be discharged to a specific location in a direction. As a result, after long-term use, the water vapor in the exhaust gas is prone to corroding the parts inside the sparkling water machine. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide an exhaust valve structure for a bubble water machine that can directionally control the gas emission location.

[0004] The technical solution adopted by this utility model to solve the problem is: an exhaust valve structure for an aerated water machine, comprising:

[0005] The gas path body has an operating chamber and an exhaust chamber. The end of the exhaust chamber is connected to the end of the operating chamber through a first connecting hole. The bottom of the gas path body has an air intake channel that is connected to the operating chamber or the first connecting hole. The outer surface of the gas path body has an operating hole that is connected to the operating chamber. The operating hole and the first connecting hole are located at both ends of the operating chamber. The exhaust chamber has an exhaust hole that connects to the outside of the gas path body.

[0006] An exhaust valve is arranged in the exhaust chamber and used to close the first connecting hole. A first return spring is provided in the exhaust chamber to drive the exhaust valve to close the first connecting hole.

[0007] An operating valve stem includes a front drive valve section, a middle sealing valve section, and a rear operating valve section. The operating valve stem is inserted into the operating chamber. The drive valve section is inserted into the operating hole and extends to the outside of the gas path body. The sealing valve section seals against the inner wall of the operating chamber. The operating valve section can push the exhaust valve.

[0008] A second reset spring is arranged in the operating chamber and connected to the operating valve stem. The second reset spring can drive the operating valve stem to move toward the operating hole.

[0009] A duct is provided on the outside of the main body of the air passage, and a duct channel is provided on the duct to communicate with the exhaust port.

[0010] Pressing the valve section on the outside of the main air passage can push the exhaust valve to move within the exhaust chamber, thereby allowing the intake passage to connect unobstructed with the exhaust port in the exhaust chamber through the first connecting hole.

[0011] As a further improvement to the above technical solution, the gas path body is provided with a pressure relief chamber that is connected to the operating chamber or the first connecting hole through a second connecting hole. The pressure relief chamber is provided with a pressure relief valve head for closing the second connecting hole. The pressure relief chamber is provided with a third return spring for connecting to the pressure relief valve head and driving the pressure relief valve head to close the second connecting hole. The pressure relief chamber is provided with a pressure relief hole connected to the outside of the gas path body. When the pressure relief valve head moves, it can make the second connecting hole and the pressure relief hole communicate without obstruction. The air guide channel is connected to the pressure relief hole.

[0012] As a further improvement to the above technical solution, the outer side of the air passage body is provided with a first mating part on the exhaust port and a second mating part on the pressure relief port. The air guide pipe is provided with a first connecting part and a second connecting part that communicate with the air guide channel. The first connecting part is sleeved on the first mating part, and the second connecting part is sleeved on the second mating part. The air guide pipe is provided with bolts that connect to the air passage body.

[0013] As a further improvement to the above technical solution, the end of the air guide tube includes a connecting port, and an air guide hose is connected to the connecting port.

[0014] As a further improvement to the above technical solution, a valve is detachably connected to the main body of the air circuit. The valve is cross-shaped, forming an upper valve pipe, a lower valve pipe, a left valve pipe, and a right valve pipe. The air intake channel is located in the lower valve pipe, the pressure relief chamber is located in the upper valve pipe, the operating chamber is located in the left valve pipe, and the exhaust chamber is located in the right valve pipe.

[0015] As a further improvement to the above technical solution, the vent hole is arranged in the middle of the outer surface of the right valve pipe, the pressure relief hole is arranged in the middle of the outer surface of the upper valve pipe, and the vent hole and the pressure relief hole are located on the same side of the valve.

[0016] As a further improvement to the above technical solution, the end of the exhaust valve is provided with a push rod that extends from the first connecting hole into the operating chamber.

[0017] The beneficial effects of this utility model are as follows: Under normal working conditions, the first reset spring controls the operating valve rod to be located at the end of the operating chamber near the operating hole, and the driving valve section extends to its maximum distance to the outside of the air passage body. At this time, the operating valve section does not contact the exhaust valve, and the exhaust valve completely closes the first connecting hole. When exhaust is required, the driving component arranged in the sparkling water machine cooperates with the driving valve section and presses the driving valve section, causing the driving valve section to push the exhaust valve to move in the exhaust chamber. This allows the air intake channel to connect unobstructed with the exhaust hole in the exhaust chamber through the first connecting hole, thereby expelling carbon dioxide gas from the sparkling water bottle. The expelled carbon dioxide gas is guided to a specific area through the air guide pipe arranged on the outside of the air passage body, thus preventing the moisture in the expelled carbon dioxide gas from corroding the parts.

[0027] according to Figures 1 to 4 An exhaust valve structure for a sparkling water machine, comprising:

[0028] The air passage body 10 is provided with an operating chamber 20 and an exhaust chamber 30. The end of the exhaust chamber 30 is connected to the end of the operating chamber 20 through a first connecting hole 102. The bottom of the air passage body 10 is provided with an air intake channel 101 that is connected to the operating chamber 20 or the first connecting hole 102. The outer surface of the air passage body 10 is provided with an operating hole 201 that is connected to the operating chamber 20. The operating hole 201 and the first connecting hole 102 are located at both ends of the operating chamber 20. The exhaust chamber 30 is provided with an exhaust hole 301 that is connected to the outside of the air passage body 10.

[0029] An exhaust valve 31 is arranged in the exhaust chamber 30 and is used to close the first connecting hole 102. A first return spring 50 is provided in the exhaust chamber 30 to drive the exhaust valve 31 to close the first connecting hole 102.

[0030] The operating valve stem 21 includes a front drive valve section 211, a middle sealing valve section 212, and a rear operating valve section 213. The operating valve stem 21 is inserted into the operating chamber 20. The drive valve section 211 is inserted into the operating hole 201 and extends to the outside of the gas path body 10. The sealing valve section 212 seals with the inner wall of the operating chamber 20. The operating valve section 213 can push the exhaust valve 31.

[0031] The second reset spring 51 is arranged in the operating cavity 20 and connected to the operating valve stem 21. The second reset spring 51 can drive the operating valve stem 21 to move toward the operating hole 201.

[0032] Air guide pipe 40, the air guide pipe 40 is arranged on the outside of the air passage body 10, and the air guide pipe 40 is provided with an air guide channel that communicates with the exhaust port 301.

[0033] Pressing the drive valve section 211 on the outside of the air passage body 10 can cause the operating valve rod 21 to push the exhaust valve 31 to move within the exhaust chamber 30, thereby allowing the intake passage 101 to communicate unobstructed with the exhaust port 301 in the exhaust chamber 30 through the first connecting hole 102.

[0034] Under normal operating conditions, the first return spring 50 controls the operating valve rod 21 to be located at the end of the operating chamber 20 near the operating hole 201. The driving valve section 211 extends to its maximum distance outside the air passage body 10. At this time, the operating valve section 213 does not contact the exhaust valve 31, and the exhaust valve 31 completely closes the first connecting hole 102. When exhaust is required, the driving component arranged in the sparkling water machine cooperates with the driving valve section 211 and presses the driving valve section 211, causing the driving valve section 211 to push the exhaust valve 31 to move in the exhaust chamber 30. This allows the air intake channel 101 to communicate unobstructedly with the exhaust hole 301 in the exhaust chamber 30 through the first connecting hole 102, thereby expelling carbon dioxide gas from the sparkling water bottle. The expelled carbon dioxide gas is guided to a specific area through the air guide pipe 40 arranged outside the air passage body 10, thus preventing the moisture in the expelled carbon dioxide gas from corroding the parts.

[0035] To facilitate the cooperation between the exhaust valve 31 and the operating valve section 213, it is preferable that the end of the exhaust valve 31 is provided with a push rod 311 that extends from the first connecting hole 102 into the operating chamber 20.

[0036] Further optimization involves providing a pressure relief chamber 60 on the gas path body 10, which communicates with the operating chamber 20 or the first connecting hole 102 via a second connecting hole 103. The pressure relief chamber 60 contains a pressure relief valve head 61 for closing the second connecting hole 103. A third return spring 52 is also provided within the pressure relief chamber 60 to connect with and drive the pressure relief valve head 61 to close the second connecting hole 103. The pressure relief chamber 60 has a pressure relief hole 601 connected to the outside of the gas path body 10. When the pressure relief valve head 61 moves, it allows unobstructed communication between the second connecting hole 103 and the pressure relief hole 601. The gas guide channel communicates with the pressure relief hole 601. This additional pressure relief chamber 60 ensures that when the gas pressure in the sparkling water bottle becomes too high, the pressure relief valve automatically opens, allowing the gas to be discharged along the pressure relief hole 601 into the gas guide pipe 40, thus preventing excessive pressure from causing the bottle to explode.

[0037] To further optimize the installation of the air guide pipe 40, it is preferable that the outer side of the air passage body 10 is provided with a first mating part 115 on the exhaust port 301 and a second mating part 116 on the pressure relief port 601. The air guide pipe 40 is provided with a first connecting part and a second connecting part communicating with the air guide channel. The first connecting part is sleeved on the first mating part 115, and the second connecting part is sleeved on the second mating part 116. The air guide pipe 40 is provided with bolts connecting to the air passage body 10. Further optimization is preferred to include a connecting port at the end of the air guide pipe 40, to which a flexible air guide hose is connected, thereby facilitating easier arrangement.

[0038] In this design, for ease of processing, it is preferable that a valve 11 is detachably connected to the main air passage 10. The valve 11 is cross-shaped, forming an upper valve pipe 111, a lower valve pipe 112, a left valve pipe 113, and a right valve pipe 114. The air intake passage 101 is located in the lower valve pipe 112, the pressure relief chamber 60 is located in the upper valve pipe 111, the operating chamber 20 is located in the left valve pipe 113, and the exhaust chamber 30 is located in the right valve pipe 114. Preferably, the exhaust port 301 is located in the middle of the outer surface of the right valve pipe 114, and the pressure relief port 601 is located in the middle of the outer surface of the upper valve pipe 111. The exhaust port 301 and the pressure relief port 601 are located on the same side of the valve 11. Of course, this is just one implementation method for ease of processing. Other methods that can achieve the same functional effect are also possible. For example, the operating chamber 20 can be arranged on the left side of the gas path body 10, and the exhaust chamber 30 and the pressure relief chamber 60 can be arranged in parallel on the right side of the operating chamber 20. The first connecting hole 102 and the second connecting hole 103 can also be arranged in parallel to connect the exhaust chamber 30 with the operating chamber 20 and the pressure relief chamber 60 with the operating chamber 20. Such specific structures can be adjusted according to actual space requirements, so they will not be described in detail here.

[0039] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
