Technical Field

[0001] This utility model relates to the field of sparkling water machines, and in particular to a sparkling water machine that uses an air spring. Background Technology

[0002] A sparkling water machine is a device used to prepare sparkling water. Currently, there are two types of sparkling water machines: one uses a large-capacity carbon dioxide cylinder, and the other uses a small-capacity carbon dioxide cartridge. The purpose of using a cartridge is to save carbon dioxide consumption, making it suitable for users with low usage frequency, as illustrated by a general-purpose sparkling water machine disclosed in patent publication number CN216962154U. However, current sparkling water machines using cartridges have drawbacks: their functionality is relatively limited, they cannot filter the incoming carbon dioxide gas, their carbon dioxide dissolution efficiency is low, and because the carbon dioxide injection process rapidly absorbs heat, the nozzle is prone to icing and clogging. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a sparkling water machine that uses an air cartridge to filter carbon dioxide gas while avoiding the problem of air nozzle icing.

The drive linkage passes through the through hole and is connected to the slow-release valve body. A quick-release return spring is provided in the exhaust valve cavity and connected to the quick-release valve body. The quick-release return spring is used to drive the quick-release valve body to descend in the exhaust valve cavity, thereby closing the exhaust valve passage with the quick-release valve head. When the slow exhaust valve body rises to abut against the top surface of the exhaust valve chamber, the continued rise of the slow exhaust valve chamber can drive the fast exhaust valve body to rise in the exhaust valve chamber.

[0007] As a further improvement to the above technical solution, a slow-release return spring is provided in the slow-release valve cavity, which is connected to the slow-release valve body and drives the slow-release valve body to close the slow-release valve passage.

[0008] As a further improvement to the above technical solution, the exhaust switch is horizontally pivotally connected to the main body, and the bottom of the exhaust switch is provided with a limiting groove with a lower opening.

[0014] The beneficial effects of this utility model are as follows: When in use, the gas cartridge is inserted into the gas cartridge installation port, an appropriate amount of water is added to the sparkling water bottle and installed in the installation position, and then the upper pressure cap is closed. By driving the upper pressure cap to move, the gas cartridge is squeezed, causing the gas cartridge to be punctured by the air inlet needle. Carbon dioxide gas enters the space between the air inlet pipe and the filter pipe along the air inlet hole. During the continuous injection of carbon dioxide gas, it is filtered by the filter pipe and injected into the air guide groove on the vortex nozzle along the one-way valve. Since the air guide groove is spiral, the carbon dioxide gas enters the nozzle in a vortex shape and is then ejected. Because the ejected carbon dioxide gas is spiral, the turbulence it generates is stronger and will produce a greater impact effect at the end of the nozzle. Therefore, even if ice forms at the end of the nozzle, it will be easily broken by the spiral carbon dioxide airflow, and the carbon dioxide gas can diffuse into the water more quickly, thereby improving the dissolution efficiency and completing the preparation of sparkling water faster. After completion, the exhaust switch is controlled to drive the exhaust valve body to move, thereby connecting the exhaust valve channel with the exhaust hole for exhaust operation.

[0021] Reference Figures 1 to 12 A sparkling water machine using an air bomb, comprising: The main body 10 has a mounting position 11 for connecting to a water bottle and an air inlet pipe 12 arranged on the mounting position 11 at its bottom. The main body 10 has an air cartridge mounting port 13 and an air inlet needle 14 located at the bottom of the air cartridge mounting port 13. The bottom of the air inlet needle 14 or the air cartridge mounting port 13 has an air inlet hole 141 that communicates with the air inlet pipe 12. A filter tube 20 is disposed in the air intake pipe 12. The top end of the filter tube 20 is closed, and a one-way valve 30 is disposed at the bottom of the filter tube 20. The input end of the one-way valve 30 is connected to the filter tube 20. A vortex nozzle 40 is disposed in the air intake pipe 12 and located at the bottom of the one-way valve 30. The vortex nozzle 40 is provided with a spiral air guide groove 41 that is connected to the output end of the one-way valve 30. Nozzle 50, wherein the nozzle 50 is disposed at the end of the air intake pipe 12; The upper pressure cover 60 is installed on the top of the main body 10. When the upper pressure cover 60 is installed on the top of the main body 10, the upper pressure cover 60 and the gas bullet mounting port 13 together form a mounting cavity for placing the gas bullet. The upper pressure cover 60 can move axially on the top of the main body 10 to drive the gas bullet to move in the gas bullet mounting port 13. An exhaust valve chamber 70 is disposed in the main body 10. The bottom of the exhaust valve chamber 70 is provided with an exhaust valve passage 71 that connects to the mounting position 11. The exhaust valve chamber 70 is provided with an exhaust hole 72 that directly or indirectly connects to the outside of the main body 10. An exhaust valve body is disposed inside the exhaust valve passage 71. An exhaust switch 73 is disposed on the surface of the main body 10 and is used to connect with the exhaust valve body. The exhaust switch 73 is used to drive the exhaust valve body to move, thereby connecting or closing the exhaust port 72 and the exhaust valve passage 71.

[0022] To use, insert the gas canister into the gas canister mounting port 13, fill the sparkling water bottle with an appropriate amount of water and install it on the mounting position 11, then cover it with the upper pressure cap 60. By driving the upper pressure cap 60 to move, the gas canister is squeezed, causing it to be punctured by the air inlet needle 14. Carbon dioxide gas enters the space between the air inlet pipe 12 and the filter pipe 20 along the air inlet hole 141. As the carbon dioxide gas is continuously injected, it is filtered by the filter pipe 20 and injected into the air guide groove 41 on the vortex nozzle 40 along the one-way valve 30. Since the air guide groove 41 is spiral-shaped, the carbon dioxide gas forms a vortex. The carbon dioxide gas enters the nozzle 50 and is ejected. Because the ejected carbon dioxide gas is spiral-shaped, it generates stronger turbulence and produces a greater impact effect at the end of the nozzle 50. Therefore, even if ice forms at the end of the nozzle 50, it will be easily broken up by the spiral carbon dioxide gas flow. This allows the carbon dioxide gas to diffuse into the water more quickly, thereby improving the dissolution efficiency and making the preparation of sparkling water faster. After completion, the exhaust switch 73 is controlled to drive the exhaust valve body to move, thereby connecting the exhaust valve channel 71 with the exhaust port 72 to perform the exhaust operation.

[0023] There are many ways in which the exhaust switch 73 and the exhaust valve body can cooperate. For example, a rack can be provided on the side of the exhaust valve body, and the exhaust switch 73 can be a gear that meshes with the rack. The rotation of the gear drives the rack to rise and fall, thereby driving the exhaust valve body to move. Considering the stability and robustness of the structure, it is preferable that a drive linkage 74 is connected to the exhaust valve body, and the exhaust switch 73 is rotatably mounted on the main body 10. The exhaust switch 73 is provided with a drive linkage 74 connected to the exhaust valve body. The main body 10 is provided with a mating bracket 79 that abuts against the exhaust switch 73. The exhaust switch 73 and / or the mating bracket 79 are provided with a first guide slope 791. When the exhaust switch 73 rotates, it can drive the exhaust valve body to rise and fall through the first guide slope 791. In this way, when the exhaust switch 73 rotates, it will move relative to the mating bracket 79 through the first guide slope 791. During the movement, the height of the first guide slope 791 changes, causing the height of the exhaust switch 73 to change, thereby driving the exhaust valve body to rise and fall.

[0024] In this solution, the filter tube 20 can be made of various existing materials such as filter sponge and activated carbon.

[0025] In order to control exhaust efficiency and adjust the exhaust speed, the exhaust valve body preferably includes: A quick-exhaust valve body 75 is disposed in the exhaust valve chamber 70 and can move up and down in the exhaust valve chamber 70. A slow-exhaust valve chamber 751 is disposed in the quick-exhaust valve body 75. A perforation is provided at the top of the slow-exhaust valve chamber 751. A quick-exhaust valve head 752 for closing the exhaust valve passage 71 is provided at the bottom of the quick-exhaust valve head 752. A slow-exhaust valve passage 753 communicating with the slow-exhaust valve chamber 751 is provided at the bottom of the quick-exhaust valve head 752. Slow-release valve body 76, which is disposed in the slow-release valve cavity 751 and can be raised and lowered in the slow-release valve cavity 751 to close or open the slow-release valve passage 753, and the drive connecting rod 74 passes through the through hole and is connected to the slow-release valve body 76. A quick-release return spring 77 is disposed in the exhaust valve cavity 70 and connected to the quick-release valve body 75. The quick-release return spring 77 is used to drive the quick-release valve body 75 to descend in the exhaust valve cavity 70, thereby causing the quick-release valve head 752 to close the exhaust valve passage 71. When the slow exhaust valve body 76 rises to abut against the top surface of the exhaust valve chamber 70, the slow exhaust valve chamber 751 continues to rise, which can drive the fast exhaust valve body 75 to rise in the exhaust valve chamber 70.

[0026] In this way, during the process of the exhaust switch 73 driving the slow exhaust valve body 76 to rise via the drive linkage 74, if the rise is small, the slow exhaust valve body 76 only rises within the slow exhaust valve chamber 751. At this time, the carbon dioxide gas in the sparkling water bottle is exhausted through the smaller slow exhaust valve passage 753 on the fast exhaust valve head 752. The exhaust speed is small at this time. When the slow exhaust valve body 76 rises to abut against the top surface of the fast exhaust valve chamber and continues to rise, the slow exhaust valve body 76 will drive the fast exhaust valve body 75 to rise within the exhaust valve chamber 70, thereby fully opening the exhaust valve passage 71 on the fast exhaust valve head 752, and thus allowing the carbon dioxide gas in the sparkling water bottle to be quickly discharged. It can be seen that by controlling the rotation amplitude of the exhaust switch 73, the exhaust efficiency of fast and slow exhaust can be controlled. The purpose of the fast exhaust return spring 77 is to ensure that when the slow exhaust valve body 76 only rises and falls within the slow exhaust valve chamber 751, the fast exhaust valve body 75 can stably close the exhaust valve passage 71. For stability, a slow-release return spring 78 is preferably provided in the slow-release valve cavity 751, which is connected to the slow-release valve body 76 and drives the slow-release valve body 76 to close the slow-release valve passage 753.

[0027] In this design, if the exhaust switch 73 is directly connected to the drive linkage 74, the exhaust switch 73 will also change height when rotating. This requires sufficient space for the exhaust switch 73 to rise and fall on the surface of the main body 10. However, this could easily cause debris to get stuck in the path of the exhaust switch 73. Therefore, it is preferable that the exhaust switch 73 is horizontally pivotally connected to the main body 10. The bottom of the exhaust switch 73 is provided with a limiting groove 731 with a downward opening. A lifting drive member 732 capable of rising and falling is arranged in the limiting groove 731. The drive linkage 74 is connected to the lifting drive member 732. The lifting drive member 732 is used to abut against the mating bracket 79. The first guide slope 791 is provided on the bottom surface of the lifting drive member 732 and / or the top surface of the mating bracket 79. With this structural arrangement, the exhaust switch 73 only needs to rotate in the horizontal direction without changing its height. The change in height is indirectly achieved by the lifting drive member 732 rising and falling in the limiting groove 731 at the bottom of the exhaust switch 73.

[0028] Further optimization is preferred, with a slot 7321 at the bottom of the drive lifting component 732 and an overstepping protrusion 792 on the top surface of the mating bracket 79. The overstepping protrusion 792 can engage with the slot 7321. The side of the overstepping protrusion 792 and / or the inner wall of the slot 7321 are provided with a second guide slope 7921. The second guide slope 7921 allows the slot 7321 to pass over the overstepping protrusion 792. When the overstepping protrusion 792 is located in the slot 7321, the drive lifting component 732 is at its lowest position and the exhaust switch 73 is at the outermost edge of its rotation stroke. This position ensures that the exhaust switch 73 is at the outermost edge. When the entire sparkling water machine is in an unvented state, the drive lifting component 732 locks the exhaust switch 73 by engaging the slot 7321 with the overstepping protrusion 792. When venting is required, a certain amount of force needs to be applied to the exhaust switch 73 to make the slot 7321 on the drive lifting component 732 move past the overstepping protrusion 792 in order to vent.

[0029] Further optimization is preferred, where an air guide seat 80 is provided at the top of the filter pipe 20 within the air intake pipe 12. The bottom of the air guide seat 80 has a blind groove for the top of the air intake pipe 12 to be inserted, thus sealing the top of the air intake pipe 12. A flange portion 83 is provided on the periphery of the air guide seat 80 to fix it to the inner wall of the air intake pipe 12. Several first diversion grooves 81 are provided at the top of the air guide seat 80, and several second diversion grooves 82 extending to the edge of the flange portion 83 are provided on the periphery of the air guide seat 80. In this way, the carbon dioxide gas in the gas cartridge, after flowing into the air intake pipe 12 through the air inlet 141, will first impact the top of the air guide seat 80, and then diffuse evenly along the first and second diversion grooves 81 and 82 to the periphery of the filter pipe 20. Furthermore, the air guide seat 80 also serves to fix and seal the top of the filter pipe 20. Of course, the most preferred method is to further add a sealing pin 21 to the top of the filter pipe 20 for further sealing.

[0030] Further optimization is preferred, with an inverted conical air guide head 42 at the bottom of the vortex nozzle 40, a vortex cavity 43 at the top of the vortex nozzle 40, an inwardly recessed guide groove 44 on the inner wall of the vortex cavity 43, and air guide grooves 41 evenly arranged on the outer periphery of the air guide head 42 and connected to the bottom of the guide groove. This structure makes it easier for the air guide grooves 41 to guide the airflow to form a vortex.

[0031] Further optimization involves providing a nozzle 50 with a gradually decreasing diameter injection orifice. This orifice comprises an upper large conical section, a middle cylindrical section, a lower compression conical section, and a bottom cylindrical air outlet. The inner wall of the compression conical section extends to the bottom edge of the cylindrical air outlet, and the air guide head 42 is inserted into the large conical section. This way, when the airflow exits along the bottom of the cylindrical air outlet, the powerful vortex-like airflow impacts the bottom edge of the nozzle 50, further breaking up any ice that may form, thus preventing ice blockage.

[0032] Further optimization is preferred, where the top of the main body 10 is provided with an external thread, and the bottom of the upper pressure cover 60 is provided with an internal thread that screws into the external thread. This way, as long as the upper pressure cover 60 rotates relative to the top of the main body 10, it can be displaced in the height direction after installation, thereby driving the air spring to press down. Of course, in other embodiments, the upper pressure cover 60 can also be directly controlled by the user pressing it in the height direction, or other structures can be used for driving; these will not be elaborated upon here.

[0033] Further optimization involves providing two pressure-regulating valve bodies 90 on the main body 10. Each pressure-regulating valve body 90 includes a pressure-regulating valve chamber 91 connected to the mounting position 11 and a pressure-regulating valve core 92 located within the pressure-regulating valve chamber 91. A pressure-regulating spring is connected to the pressure-regulating valve core 92. The two pressure-regulating valve bodies 90 can prevent the gas pressure inside the sparkling water bottle from exceeding the standard. They also serve as backups for each other, preventing the inability to regulate pressure if one of the pressure-regulating valve bodies 90 malfunctions.

[0034] In this scheme, in order to further reduce the condensation and adhesion of ice to the nozzle 50, it is preferable that both the inner and outer surfaces of the nozzle 50 are lined with a material layer with a low coefficient of friction and low or no adhesion to any substance.

[0035] 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.
