Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to a pressure relief and defogging structure and a coffee machine. Background Technology

[0002] In existing technology, the limited number of pressure relief vents in coffee machines prevents the rapid drainage of excess water. This causes residual water in the pipes to interfere with the pressure relief process, leading to increased pressure in the machine's piping. Excessive pressure can damage internal pipes, valves, and other equipment, and may even cause pipe ruptures and water leaks. Furthermore, the limited number of pressure relief vents prevents the efficient removal of steam generated inside the machine. This can mislead operators into believing the machine is malfunctioning and can also cause internal electronic components to become damp, potentially leading to short circuits and other damage. Utility Model Content

[0003] Therefore, it is necessary to address the issue of the limited number of pressure relief ports in the pressure relief and defogging structures of coffee machines by providing a pressure relief and defogging structure and a coffee machine in general.

[0004] A pressure relief and demisting structure includes: an external component having an inlet channel; a pressure relief component having the external component mounted on it, the external component and the pressure relief component forming a pressure relief cavity for buffering liquid and / or gas entering from the inlet channel; and a support component having the pressure relief component mounted on it, the support component having a pressure relief channel and a discharge cavity, the inlet channel, the pressure relief cavity, the pressure relief channel and the discharge cavity being sequentially connected.

[0005] The aforementioned pressure relief and demisting structure offers several advantages. Firstly, regarding safety, the inlet channel of the external component, the pressure relief chamber of the pressure relief component, and the pressure relief channel and outlet chamber of the supporting component are sequentially connected, forming a complete and effective pressure relief path. When the pressure in the steam boiler or pipeline is too high, the high-temperature, high-pressure liquid or gas can quickly enter the pressure relief chamber through the inlet channel for buffering, preventing dangerous situations such as boiler explosions caused by sudden pressure increases. This significantly improves the safety of the coffee machine and creates a reassuring operating environment for users. Simultaneously, because the pressure relief and demisting structure can discharge excess steam to the wastewater box, it prevents users from mistakenly believing the coffee machine is damaged due to visible steam leaks elsewhere. Secondly, through effective control of the pressure relief process, the pressure and steam state entering the coffee extraction structure can be precisely adjusted. Stable and suitable pressure helps to evenly extract coffee powder, allowing the flavor compounds of the coffee to be fully released, thereby improving the taste and aroma of the coffee and ensuring that every cup of coffee reaches the optimal quality standard, satisfying coffee lovers' pursuit of high-quality coffee. Finally, regarding the overall performance and lifespan of the coffee machine, this pressure relief and defogging structure effectively reduces the impact and erosion of steam and liquid on internal components. The rational design of the pressure relief chamber and discharge chamber guides the high-temperature, high-pressure medium out of the machine in an orderly manner, reducing the risk of damage to critical components due to long-term exposure to unstable pressure and humid environments. This extends the coffee machine's lifespan, reduces maintenance costs and the frequency of parts replacement, bringing economic benefits to both businesses and home users. The pressure relief and defogging structure of this application provides strong protection for the safe and stable operation of the coffee machine, improves coffee quality, and ensures long-term durability; it is key to the coffee machine's efficient and high-quality operation.

[0006] In one embodiment, the pressure relief chamber includes a first pressure relief chamber, a second pressure relief chamber, and a third pressure relief chamber. There are multiple first pressure relief chambers, located at both ends of the pressure relief assembly. There are also multiple second pressure relief chambers, located inside the first pressure relief chambers. The third pressure relief chamber is sandwiched between the second pressure relief chambers. The first, second, and third pressure relief chambers are connected, and both the second and third pressure relief chambers are connected to the pressure relief channel. By placing two first pressure relief chambers on either side of the pressure relief assembly, placing two second pressure relief chambers inside the first pressure relief chambers, and finally sandwiching the third pressure relief chamber between the two second pressure relief chambers, the multi-layered pressure relief chamber design brings several advantages to the pressure relief and demisting structure. First, in terms of pressure buffering capacity, the outermost first pressure relief chamber can buffer larger air or water pressures. When a sudden pressure change occurs in the steam boiler or pipeline, a large amount of high-pressure liquid and gas first impacts this area. The first pressure relief chamber, with its reasonable structural design and large volume, effectively disperses and initially reduces the pressure peak, preventing the instantaneous high pressure from directly impacting the entire coffee machine system. This greatly enhances the coffee machine's pressure resistance and ensures its stability and safety under high load operation. The second pressure relief chamber can handle relatively lower pressures in the steam boiler or pipeline, or buffer the water pressure from the first pressure relief chamber. The buffered water flow can then be discharged through the pressure relief channel, while the higher-pressure water flow can continue to the third pressure relief chamber for further pressure relief. When the pressure in the pipeline is not too high, it can flow into the third pressure relief chamber, and finally, the water or steam is discharged through the pressure relief channel. This layered and progressive pressure relief method precisely controls the pressure release process, ensuring not only the safe operation of the coffee machine but also making the pressure during coffee extraction more stable and suitable. This helps improve the extraction quality and consistency of the coffee's taste, providing users with a superior coffee experience.

[0007] In one embodiment, the cross-sectional area of ​​the portion of the pressure relief channel communicating with the second pressure relief chamber is smaller than the cross-sectional area of ​​the portion communicating with the third pressure relief chamber. By setting the area of ​​the pressure relief channel located in the second pressure relief chamber to be smaller than the area of ​​the pressure relief channel located in the third pressure relief chamber, the liquid or gas flowing into the pressure relief channel from the second pressure relief chamber is subject to a certain flow restriction. This helps to further control the pressure release rate, especially when dealing with large initial pressures, preventing a sudden surge of pressure into the subsequent discharge chamber, thereby avoiding the impact on the entire system due to sudden pressure changes. The larger cross-sectional area of ​​the third pressure relief chamber provides a relatively smoother discharge path for the pressure after initial fine adjustment, ensuring a smooth transition and effective dissipation of pressure throughout the entire pressure relief process, so that the system pressure is always maintained within a stable and safe range, ensuring the stable operation of the coffee machine and avoiding malfunctions due to pressure runaway. In fact, the smaller cross-sectional area of ​​the pressure relief channel connected to the second pressure relief chamber effectively prolongs the residence time of the liquid or gas in the pressure relief chamber, allowing the second pressure relief chamber to more fully exert its buffering effect and improving buffering efficiency. The third pressure relief chamber is connected to a pressure relief channel with a larger cross-sectional area. This allows for the rapid discharge of residual pressure once the pressure has been well controlled. This ensures the efficiency of the overall pressure relief process and, based on the initial buffering, further enhances the stability and safety of the internal pressure environment of the coffee machine. It also ensures that processes such as coffee extraction can be carried out under stable pressure conditions, which helps to improve the quality and taste of the coffee.

[0008] In one embodiment, the cross-sectional area of ​​the inlet channel is smaller than that of the pressure relief channel. Making the inlet channel smaller than the pressure relief channel provides significant advantages for pressure relief. In terms of pressure control, a smaller inlet channel limits the rapid influx of liquid or gas, preventing instantaneous high-pressure impacts on the interior of the pressure relief and demisting structure, thus providing initial pressure stabilization. A larger pressure relief channel, on the other hand, efficiently and quickly discharges the buffered medium from the pressure relief chamber at low pressure, preventing pressure buildup within the coffee machine, ensuring stable equipment operation, and reducing the risk of malfunctions caused by abnormal pressure. Secondly, this design helps improve coffee extraction quality. A stable pressure environment makes the coffee extraction process more uniform and thorough, ensuring consistent and high-quality coffee flavor and providing users with a superior coffee experience.

[0009] In one embodiment, the cross-sectional area of ​​the pressure relief channel is smaller than the cross-sectional area of ​​the discharge chamber. By making the area of ​​the pressure relief channel smaller than the area of ​​the discharge chamber, significant advantages are gained in pressure relief. The relatively smaller pressure relief channel can limit the flow of liquid and gas from the pressure relief chamber, resulting in a smoother and more stable pressure release, ensuring the reliability of the equipment operation. Meanwhile, the larger cross-sectional area discharge chamber, connected to the wastewater box, provides ample discharge space for the medium buffered by the pressure relief channel, allowing it to flow quickly and efficiently into the wastewater box, effectively preventing the accumulation of residual medium inside the coffee machine.

[0010] In one embodiment, the pressure relief assembly and the support assembly are integrally formed. By integrally forming the pressure relief assembly and the support assembly, potential gaps and looseness at the connection points are eliminated, making the entire structure more robust and durable. When the coffee machine faces pressure changes, vibrations, or other situations during operation, the integrated structure can evenly distribute stress, effectively preventing damage caused by relative displacement between components, greatly improving the reliability and lifespan of the equipment. Simultaneously, the integral forming ensures the sealing and continuity between the pressure relief chamber and the pressure relief channel, making pressure transmission and release more stable and efficient. No pressure leakage or uneven pressure relief will occur due to minor gaps or unevenness at the connection points, thus ensuring that the internal pressure of the coffee machine remains safe and stable. This provides a reliable pressure environment for precise coffee extraction, helping to improve the quality and taste of the coffee, allowing users to enjoy a higher quality coffee beverage.

[0011] In one embodiment, the pressure relief assembly includes connecting columns, a pressure relief shell, and pressure relief baffles. The pressure relief shell is mounted on the support assembly. Multiple connecting columns are positioned on both sides of the pressure relief shell. Multiple pressure relief baffles are spaced along the length of the pressure relief shell. The external component is mounted on the connecting columns. By positioning multiple connecting columns on both sides of the pressure relief shell and mounting the shell on the support assembly, a stable support connection point is provided for the external component, ensuring the connection stability between the external component and the pressure relief assembly. This effectively prevents components from loosening or shifting due to vibration or pressure impact during coffee machine operation, thus ensuring the reliability of the entire pressure relief system. Furthermore, the multiple pressure relief baffles spaced along the length of the pressure relief shell can repeatedly divert and block liquids and gases entering the pressure relief chamber, further optimizing the pressure buffering effect. This layered blocking and buffering mechanism allows pressure to be distributed more evenly within the pressure relief chamber, reducing the possibility of damage to components caused by excessive local pressure. It also helps to improve the stability and controllability of the pressure relief process, thereby enhancing the overall performance and lifespan of the coffee machine and providing users with a more stable and efficient coffee-making experience.

[0012] In one embodiment, the external component extends into the pressure relief chamber, and the horizontal plane of the end of the external component extending into the pressure relief chamber is lower than the horizontal plane of the top of the pressure relief baffle. By inserting the external component's connector into the pressure relief chamber, it is ensured that the liquid or gas requiring pressure relief completely enters the pressure relief chamber, effectively preventing liquid from directly overflowing from the external component into the pressure relief chamber. This avoids potential leakage problems, ensures the cleanliness and safety of the coffee machine's internal environment, and reduces the risk of short circuits or corrosion caused by liquid leakage to other components. Secondly, the higher liquid level of the pressure relief baffle provides better blocking and buffering effects. Even under large pressure fluctuations, it can stop any splashing liquid, allowing it to be fully buffered and fall back within the pressure relief chamber, maintaining a stable and orderly pressure relief process. This ensures stable operation of the coffee machine, extends its service life, and also improves the reliability and safety of the coffee making process.

[0013] In one embodiment, multiple pressure relief baffles divide the pressure relief channel into multiple segments. By using multiple pressure relief baffles to divide the pressure relief channel into multiple segments, the pressure relief process can be precisely controlled. As liquids and gases pass through each segment, they are subjected to multiple obstructions and buffering, resulting in a more stable and uniform pressure release. This protects the internal structure of the pressure relief and demisting structure and reduces the probability of damage and malfunction caused by pressure shocks. Simultaneously, the segmented structure helps improve pressure relief efficiency, allowing the medium to enter the pressure relief channel and then exit into the discharge chamber more quickly, orderly, and directly through different pressure relief chambers. This ensures the stability and safety of the coffee machine's operation and also helps maintain precise pressure control during coffee making, improving the quality and taste of the coffee.

[0014] In one embodiment, the pressure relief housing includes a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall, which are sequentially connected. The first and third sidewalls are arranged opposite to each other. A plurality of pressure relief baffles are evenly distributed on the first and third sidewalls, dividing the pressure relief chamber into a plurality of first, second, and third pressure relief chambers. The first, second, third, and fourth sidewalls are integrally formed. By evenly distributing the plurality of pressure relief baffles on the first and third sidewalls, the pressure relief chamber is reasonably divided, allowing pressure to be gradually dispersed and buffered in multiple chambers. The formation of multiple first, second, and third pressure relief chambers allows for the graded processing of incoming liquids and gases. The outermost first pressure relief chamber can withstand a larger initial pressure impact, followed by a more gradual and stable release of pressure in the second and third chambers. This avoids sudden, concentrated pressure release that could damage the coffee machine's internal structure, improving overall stability and safety. Different water or gas pressures can also be introduced into different pressure relief chambers based on actual conditions, achieving high-precision and efficient pressure relief. This uniform distribution and precise separation also helps optimize the coffee machine's pressure relief efficiency, making the process more orderly and efficient. This ensures stable operation of the coffee machine under various conditions, extending its lifespan, and providing a stable pressure environment for coffee extraction, thus improving coffee quality. Furthermore, the integrated molding of the first, second, third, and fourth sidewalls better withstands the impact of water and gas pressure, ensuring the structural stability of the pressure relief shell and providing reliable protection for the internal pressure relief process.

[0015] In one embodiment, the external component includes a base, connecting pipes, and support blocks. The base is mounted on the pressure relief component. Multiple connecting pipes are inserted through the base and spaced apart along its length. Multiple support blocks are also present, one-to-one with each of the connecting pipes. Each connecting pipe has an inlet channel. By arranging multiple connecting pipes spaced apart along the base's length, the flexibility and convenience of connecting to external devices are increased, adapting to different piping layout requirements. Whether connecting to a steam source or other liquid inputs, or water and air pressures with varying pressure values, stable and efficient transmission is ensured. The support blocks, one-to-one with each connecting pipe, not only strengthen the structural stability of the connecting pipes, preventing displacement or deformation due to vibration or pressure changes during coffee machine operation, but also ensure the inlet channels remain unobstructed and stable, thereby guaranteeing the accuracy of pressure and liquid transmission. This not only reduces the risk of leakage due to pipe instability and extends the service life of the external component, but also lays a solid foundation for the safe and stable operation of the entire coffee machine, significantly improving the reliability and quality consistency of the coffee-making process.

[0016] In one embodiment, the support assembly includes a main support housing, a pressure relief component, support connecting columns, and mounting columns. The pressure relief assembly is disposed on the main support housing, the pressure relief component is disposed on the main support housing, and there are multiple support connecting columns arranged circumferentially along the main support housing. There are also multiple mounting columns disposed on the main support housing. The main support housing has the discharge chamber, and the pressure relief component has the pressure relief channel. By arranging multiple support connecting columns circumferentially along the main support housing, a stable and uniform support force is provided, ensuring that the entire pressure relief system remains stable during coffee machine operation. This effectively resists shaking and displacement caused by internal pressure changes and mechanical vibrations, thereby improving the stability and reliability of the equipment operation and reducing the risk of malfunctions caused by loose or displaced components. The mounting columns facilitate the installation and fixation of the support assembly inside the coffee machine, improving assembly efficiency and facilitating subsequent maintenance and repair work. The pressure relief component and the main support housing are respectively equipped with pressure relief channels and discharge chambers, so that the liquid and gas flowing in from the pressure relief component can be discharged into the wastewater box in an orderly manner according to the predetermined path. The pressure release process is precisely controlled, avoiding the disorderly accumulation of pressure that could damage the inside of the coffee machine. At the same time, it ensures the stability of the pressure environment during the coffee extraction process, which helps to improve the quality and taste of the coffee and bring users a better coffee experience.

[0017] The second aspect of this application discloses a coffee machine, which includes: the aforementioned pressure relief and defogging structure; and a coffee machine body, wherein the pressure relief and defogging structure is disposed on the coffee machine body.

[0018] The second aspect disclosed above discloses a coffee machine that optimizes the use of internal space by integrating a pressure relief and defogging structure into the main body of the coffee machine. This integrated design makes the overall structure more compact and concise, reduces external connecting pipes and components, lowers the risk of malfunctions due to loose or damaged connections, and improves the stability and reliability of the equipment. Secondly, the pressure relief and defogging process is efficiently completed within the coffee machine body, promptly handling steam and pressure, preventing fog from affecting the surrounding environment and the performance of electronic components, and extending the lifespan of the equipment. Furthermore, the tightly integrated structure allows for more precise pressure control, ensuring stable pressure during coffee extraction, thereby improving the quality and taste of the coffee and providing users with a superior coffee experience.

[0031] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0033] The following describes some embodiments of the pressure relief and defogging structure and coffee machine of this utility model with reference to the accompanying drawings.

[0034] Example 1

[0035] like Figures 1 to 8 As shown, this embodiment discloses a pressure relief and demisting structure, including: an external component 1, which has an inlet channel 101; a pressure relief component 2, on which the external component 1 is disposed, and the external component 1 and the pressure relief component 2 together form a pressure relief chamber 201, which is used to buffer liquid and / or gas entering from the inlet channel 101; and a support component 3, on which the pressure relief component 2 is disposed, and the support component 3 has a pressure relief channel 301 and a discharge chamber 302, wherein the inlet channel 101, the pressure relief chamber 201, the pressure relief channel 301 and the discharge chamber 302 are sequentially connected.

[0036] This application discloses a pressure relief and demisting structure. First, in terms of safety, the inlet channel 101 of the external component 1, the pressure relief chamber 201 of the pressure relief component 2, and the pressure relief channel 301 and outlet chamber 302 of the support component 3 are sequentially connected, forming a complete and effective pressure relief path. When the pressure of the steam boiler or pipeline is too high, the high-temperature and high-pressure liquid or gas can quickly enter the pressure relief chamber 201 through the inlet channel 101 for buffering, avoiding dangerous situations such as boiler explosions that may be caused by sudden pressure increases, greatly improving the safety of coffee machine use and creating a safe operating environment for users. At the same time, because the pressure relief and demisting structure can discharge excess steam to the wastewater box, it prevents users from seeing steam leaking elsewhere and mistakenly believing that the coffee machine is damaged. Second, through effective control of the pressure relief process, the pressure and steam state entering the coffee extraction structure can be precisely adjusted. Stable and appropriate pressure helps to evenly extract coffee powder, allowing the flavor substances of coffee to be fully released, thereby improving the taste and aroma of coffee, so that every cup of coffee can reach the best quality standard and meet the pursuit of high-quality coffee by coffee lovers. Finally, regarding the overall performance and lifespan of the coffee machine, this pressure relief and defogging structure effectively reduces the impact and erosion of steam and liquid on internal components. The rational design of the pressure relief chamber 201 and the discharge chamber 302 guides the high-temperature, high-pressure medium out of the machine in an orderly manner, reducing the risk of damage to critical components due to long-term exposure to unstable pressure and humid environments. This extends the coffee machine's lifespan, reduces maintenance costs and the frequency of parts replacement, bringing economic benefits to both businesses and home users. The pressure relief and defogging structure of this application provides strong protection for the safe and stable operation of the coffee machine, improves coffee quality, and ensures long-term durability; it is key to the coffee machine's efficient and high-quality operation.

[0037] like Figure 3 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further defines that: the pressure relief chamber 201 includes a first pressure relief chamber 2011, a second pressure relief chamber 2012, and a third pressure relief chamber 2013. There are multiple first pressure relief chambers 2011, which are respectively disposed at both ends of the pressure relief assembly 2. There are multiple second pressure relief chambers 2012, which are disposed inside the multiple first pressure relief chambers 2011. The third pressure relief chamber 2013 is sandwiched between the multiple second pressure relief chambers 2012. The first pressure relief chambers 2011, the second pressure relief chambers 2012, and the third pressure relief chamber 2013 are connected. Both the second pressure relief chambers 2012 and the third pressure relief chamber 2013 are connected to the pressure relief channel 301. By placing two first pressure relief chambers 2011 on either side of the pressure relief assembly 2, placing two second pressure relief chambers 2012 inside the first pressure relief chambers 2011, and finally sandwiching a third pressure relief chamber 2013 between the two second pressure relief chambers 2012, the multi-layered pressure relief chamber design brings several advantages to the pressure relief and demisting structure. Firstly, in terms of pressure buffering capacity, the outermost first pressure relief chamber 2011 can buffer larger air or water pressures. When a sudden pressure change occurs in the steam boiler or pipeline, a large amount of high-pressure liquid and gas first impacts this area. Thanks to its reasonable structural design and large volume, the first pressure relief chamber 2011 can effectively disperse and initially reduce the pressure peak, preventing the instantaneous high pressure from directly impacting the entire coffee machine system. This greatly enhances the coffee machine's pressure resistance and ensures its stability and safety under high load operation. The second pressure relief chamber 2012 can handle relatively low pressure in the steam boiler or pipeline, or buffer the water pressure from the first pressure relief chamber 2011. The buffered water flow can then be discharged through the pressure relief channel 301, while the higher-pressure water flow can continue to the third pressure relief chamber 2013 for further pressure relief. When the pressure in the pipeline is not too high, it can be introduced into the third pressure relief chamber 2013, and finally, the water or steam will be discharged through the pressure relief channel 301. This layered and progressive pressure relief method precisely controls the pressure release process, ensuring not only the safe operation of the coffee machine but also a more stable and suitable pressure during coffee extraction, contributing to improved extraction quality and consistent taste, and providing users with a superior coffee experience.

[0038] like Figure 3 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-sectional area of ​​the portion of the pressure relief channel 301 communicating with the second pressure relief chamber 2012 is smaller than the cross-sectional area of ​​the portion of the pressure relief channel 301 communicating with the third pressure relief chamber 2013. By setting the area of ​​the pressure relief channel 301 located in the second pressure relief chamber 2012 to be smaller than the area of ​​the pressure relief channel 301 located in the third pressure relief chamber 2013, the liquid or gas flowing into the pressure relief channel 301 from the second pressure relief chamber 2012 is subject to a certain flow restriction effect. This helps to further control the pressure release rate, especially when dealing with a large initial pressure, preventing a large amount of pressure from rushing into the subsequent discharge chamber, thereby avoiding the impact on the entire system due to sudden pressure changes. The larger cross-sectional area of ​​the third pressure relief chamber provides a relatively smoother discharge path for the pressure after preliminary fine adjustment, ensuring a smooth transition and effective dissipation of pressure throughout the entire pressure relief process, so that the system pressure is always maintained within a stable and safe range, ensuring the stable operation of the coffee machine and avoiding malfunctions due to pressure runaway. In fact, the smaller cross-sectional area pressure relief channel 301 is connected to the second pressure relief chamber 2012, which effectively prolongs the residence time of liquid or gas in the pressure relief chamber, allowing the second pressure relief chamber 2012 to more fully exert its buffering effect and improve buffering efficiency. The third pressure relief chamber 2013, connected to the larger cross-sectional area pressure relief channel 301, quickly discharges residual pressure after ensuring good pressure control. This ensures the overall efficiency of the pressure relief process and, based on the initial buffering, further enhances the stability and safety of the internal pressure environment of the coffee machine. This ensures that coffee extraction and other processes can be carried out under stable pressure conditions, contributing to improved coffee quality and taste.

[0039] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-sectional area of ​​the inlet channel 101 is smaller than the cross-sectional area of ​​the pressure relief channel 301. By setting the inlet channel 101 to be smaller than the pressure relief channel 301, it brings great benefits to pressure relief. In terms of pressure control, the smaller inlet channel 101 can limit the rapid influx of liquid or gas, avoiding instantaneous high-pressure impact on the interior of the pressure relief and demisting structure, thus playing a preliminary pressure stabilizing role. The larger pressure relief channel 301 can efficiently, quickly, and at low pressure discharge the medium buffered by the pressure relief chamber 201, preventing pressure from accumulating in the coffee machine, ensuring stable operation of the equipment, and reducing the risk of malfunctions caused by abnormal pressure. Secondly, this design helps to improve the quality of coffee extraction. The stable pressure environment makes the coffee extraction process more uniform and thorough, thereby ensuring the consistency and high quality of coffee flavor, bringing users a better coffee experience.

[0040] like Figure 2 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-sectional area of ​​the pressure relief channel 301 is smaller than the cross-sectional area of ​​the discharge chamber 302. By setting the area of ​​the pressure relief channel 301 to be smaller than the area of ​​the discharge chamber 302, significant benefits are brought to pressure relief. The relatively smaller pressure relief channel 301 can limit the flow of liquid and gas flowing from the pressure relief chamber 201, making the pressure release smoother and more stable, ensuring the reliability of equipment operation. The larger cross-sectional area discharge chamber 302, which is connected to the wastewater box, provides a spacious discharge space for the medium after being buffered by the pressure relief channel 301, allowing it to flow into the wastewater box quickly and efficiently, effectively preventing the medium from accumulating inside the coffee machine.

[0041] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the pressure relief component 2 and the support component 3 are integrally molded. By integrally molding the pressure relief component 2 and the support component 3, gaps and looseness that may occur at the connection points are eliminated, making the entire structure more robust and durable. When the coffee machine faces pressure changes, vibrations, etc. during operation, the integral structure can evenly distribute stress, effectively avoiding damage caused by relative displacement between components, greatly improving the reliability and service life of the equipment. At the same time, the integral molding ensures the sealing and continuity between the pressure relief chamber 201 and the pressure relief channel 301, making the transmission and release of pressure more stable and efficient. There will be no pressure leakage or uneven pressure relief due to small gaps or unevenness at the connection points, thus ensuring that the internal pressure of the coffee machine is always in a safe and stable state, providing a reliable pressure environment for precise coffee extraction, helping to improve the quality and taste of coffee, and allowing users to enjoy a higher quality coffee beverage.

[0042] like Figure 1 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines: the pressure relief assembly 2 includes connecting columns 21, a pressure relief shell 22, and pressure relief baffles 23. The pressure relief shell 22 is disposed on the support assembly 3. Multiple connecting columns 21 are distributed on both sides of the pressure relief shell 22. Multiple pressure relief baffles 23 are spaced along the length of the pressure relief shell 22. The external assembly 1 is disposed on the multiple connecting columns 21. By distributing the multiple connecting columns 21 on both sides of the pressure relief shell 22 and placing the pressure relief shell 22 on the support assembly 3, a stable support connection point is provided for the external assembly 1, ensuring the connection stability between the external assembly 1 and the pressure relief assembly 2. This effectively prevents components from loosening or shifting due to vibration or pressure impact during coffee machine operation, thereby ensuring the reliability of the entire pressure relief system. Furthermore, the multiple pressure relief baffles 23 spaced along the length of the pressure relief shell 22 can divert and block liquids and gases entering the pressure relief chamber 201 multiple times, further optimizing the pressure buffering effect. This layered blocking and buffering mechanism allows the pressure to be distributed more evenly within the pressure relief chamber 201, reducing the possibility of damage to components caused by excessive local pressure. It also helps to improve the stability and controllability of the pressure relief process, thereby enhancing the overall performance and lifespan of the coffee machine and providing users with a more stable and efficient coffee making experience.

[0043] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the external component 1 extends into the pressure relief chamber 201, and the horizontal plane of the end of the external component 1 extending into the pressure relief chamber 201 is lower than the horizontal plane of the top of the pressure relief baffle 23. By inserting the pipe 12 of the external component 1 into the pressure relief chamber 201, it can be ensured that the liquid or gas that needs to be depressurized completely enters the pressure relief chamber 201, effectively preventing liquid from directly overflowing from the external component into the pressure relief chamber 201, avoiding possible leakage problems, ensuring the cleanliness and safety of the internal environment of the coffee machine, and reducing the risk of short circuits or corrosion of other components due to liquid leakage. Secondly, the higher liquid level of the pressure relief baffle 23 can play a better blocking and buffering role. Even when the pressure fluctuates greatly, it can block the liquid that may splash up, allowing it to be fully buffered and fall back in the pressure relief chamber 201, maintaining the stability and order of the pressure relief process, thereby ensuring the stable operation of the coffee machine, extending its service life, and also improving the reliability and safety of the coffee making process.

[0044] like Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further defines that: multiple pressure relief baffles 23 divide the pressure relief channel 301 into multiple segments. By using multiple pressure relief baffles 23 to divide the pressure relief channel 301 into multiple segments, the pressure relief process can be precisely controlled. When liquids and gases pass through each segment, they are blocked and buffered multiple times, making the pressure release more stable and uniform, protecting the internal structure of the pressure relief and demisting structure, and reducing the probability of damage and failure caused by pressure shock. At the same time, the segmented structure helps to improve pressure relief efficiency, allowing the medium to enter the pressure relief channel 301 and then be discharged to the discharge chamber 302 more quickly, orderly, and directly through different pressure relief chambers, ensuring the stability and safety of the coffee machine's operation, and also helping to maintain precise pressure control during coffee making, improving the quality and taste of the coffee.

[0045] like Figure 5 , Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines: the pressure relief shell 22 includes a first sidewall 221, a second sidewall 222, a third sidewall 223, and a fourth sidewall 224, which are connected sequentially. The first sidewall 221 and the third sidewall 223 are arranged opposite to each other. A plurality of pressure relief baffles 23 are evenly distributed on the first sidewall 221 and the third sidewall 223, dividing the pressure relief chamber 201 into a plurality of first pressure relief chambers 2011, a plurality of second pressure relief chambers 2012, and a third pressure relief chamber 2013. The first sidewall 221, the second sidewall 222, the third sidewall 223, and the fourth sidewall 224 are integrally formed. By evenly distributing the plurality of pressure relief baffles 23 on the first sidewall 221 and the third sidewall 223, the pressure relief chamber 201 is reasonably divided, so that the pressure can be gradually dispersed and buffered in multiple chambers. The formation of multiple first pressure relief chambers 2011, second pressure relief chambers 2012, and third pressure relief chambers 2013 allows for the graded processing of incoming liquids and gases. The outermost first pressure relief chamber 2011 can withstand a larger initial pressure impact, followed by a more stable release of pressure in the second and third pressure relief chambers 2012 and 2013. This avoids sudden, concentrated pressure release that could damage the coffee machine's internal components, improving overall stability and safety. Different water or gas pressures can also be introduced into different pressure relief chambers according to actual conditions, achieving high-precision and efficient pressure relief. This uniform distribution and precise separation also helps optimize the coffee machine's pressure relief efficiency, making the pressure relief process more orderly and efficient. This ensures stable operation of the coffee machine under various working conditions, extending its service life, and providing a stable pressure environment for coffee extraction, thus improving coffee quality. The first sidewall 221, the second sidewall 222, the third sidewall 223 and the fourth sidewall 224 are integrally formed, which can better withstand the impact of water pressure and air pressure, ensuring the structural stability of the pressure relief shell 22 and providing a reliable guarantee for the internal pressure relief process.

[0046] like Figure 1 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines: the external component 1 includes a base 11, connecting pipes 12, and support blocks 13. The base 11 is disposed on the pressure relief component 2. Multiple connecting pipes 12 are provided, passing through the base 11 and spaced apart along its length. Multiple support blocks 13 are provided, each corresponding to one of the connecting pipes 12. Each connecting pipe 12 has an inlet channel 101. By spaced the multiple connecting pipes 12 along the length of the base 11, the flexibility and convenience of connecting to external devices are increased, adapting to different pipeline layout requirements. Whether connecting to a steam source or other liquid inputs, or water and air pressures with different pressure values, stable and efficient transmission can be ensured. The support blocks 13, each corresponding to one of the connecting pipes 12, not only strengthen the structural stability of the connecting pipes 12, preventing displacement or deformation due to vibration or pressure changes during coffee machine operation, but also ensure that the inlet channel 101 remains unobstructed and stable, thereby guaranteeing the accuracy of pressure and liquid transmission. This not only reduces the risk of leakage caused by the instability of the connector 12 and extends the service life of the external component 1, but also lays a solid foundation for the safe and stable operation of the entire coffee machine, and effectively improves the reliability and quality consistency of the coffee making process.

[0047] like Figure 1 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines: the support assembly 3 includes a main support housing 31, a pressure relief component 32, support connecting columns 33, and mounting columns 34. The pressure relief assembly 2 is disposed on the main support housing 31, the pressure relief component 32 is disposed on the main support housing 31, the number of support connecting columns 33 is multiple, and the multiple support connecting columns 33 are arranged circumferentially along the main support housing 31. The number of mounting columns 34 is multiple, and the multiple mounting columns 34 are disposed on the main support housing 31. The main support housing 31 is provided with a discharge chamber 302, and the pressure relief component 32 is provided with a pressure relief channel 301. By arranging multiple support connecting columns 33 circumferentially along the main support housing 31, a stable and uniform support force is provided, ensuring that the entire pressure relief system can remain stable during the operation of the coffee machine, effectively resisting the shaking and displacement caused by internal pressure changes and mechanical vibrations, thereby improving the stability and reliability of the equipment operation and reducing the risk of failure caused by loose or displaced components. The mounting column 34 facilitates the installation and fixation of the support assembly 3 inside the coffee machine, improving assembly efficiency and simplifying subsequent maintenance and repair. The pressure relief component 32 and the main support housing 31 are respectively equipped with a pressure relief channel 301 and a discharge chamber 302, allowing liquids and gases flowing in from the pressure relief component 2 to be discharged into the wastewater box in an orderly manner along a predetermined path. This precise control of the pressure release process prevents disorderly pressure accumulation from damaging the inside of the coffee machine, while also ensuring a stable pressure environment during coffee extraction, contributing to improved coffee quality and taste, and providing users with a better coffee experience.

[0048] Example 2

[0049] like Figures 1 to 8 As shown, this embodiment discloses a coffee machine, including: the aforementioned pressure relief and defogging structure; and a coffee machine body, wherein the pressure relief and defogging structure is disposed on the coffee machine body.

[0050] The second aspect of this application discloses a coffee machine that optimizes the use of internal space by integrating a pressure relief and defogging structure into the machine body. This integrated design makes the overall structure more compact and concise, reduces external connecting pipes and components, lowers the risk of malfunctions due to loose or damaged connections, and improves the stability and reliability of the equipment. Secondly, the pressure relief and defogging process is efficiently completed within the coffee machine body, promptly handling steam and pressure, preventing fogging from affecting the surrounding environment and the performance of electronic components, and extending the lifespan of the equipment. Furthermore, the tightly integrated structure allows for more precise pressure control, ensuring stable pressure during coffee extraction, thereby improving the quality and taste of the coffee and providing users with a superior coffee experience.
