Abstract
Description
Technical Field
[0001] This utility model relates to milk frothing device technology, and in particular to a steam output system and a coffee machine. Background Technology
[0002] With societal development and rising demands for quality of life, coffee, as one of the most popular daily beverages, has become increasingly diverse. Adding milk to create foam enriches the flavor of coffee and is an essential step in the coffee-making process. Therefore, most coffee machines on the market are equipped with milk frothing devices. These devices work by using high-temperature steam to inject air into the milk to form foam. However, the high-temperature steam inevitably produces a large amount of condensation during its circulation within the machine, which is detrimental to coffee brewing.
[0003] Most milk frothing devices on the market currently use steam pipes to directly deliver high-temperature steam into the milk. This steam delivery process easily produces a large amount of condensation that accumulates in the steam pipes. This condensation not only causes inconvenience during coffee machine use but also affects the taste of the coffee to some extent. Therefore, it is necessary to improve the existing technology. Utility Model Content
[0004] Therefore, it is necessary to provide a steam output system to address the problem of condensate buildup during the use of milk foaming devices.
[0005] A steam output system includes: an outer pipe assembly having an installation channel, an installation opening communicating with the installation channel, and a steam outlet; an inner pipe assembly disposed on the outer pipe assembly and at least partially located within the installation channel, the inner pipe assembly having a flow passage and being used to connect to a steam input pipe; and a steam pipe assembly disposed on the outer pipe assembly, the steam pipe assembly having a steam passage, the installation opening, the flow passage, and the steam passage being sequentially connected.
[0006] This application discloses a steam output system. The outer tube assembly has strength and rigidity, capable of supporting the internal components and withstanding steam transmission pressure. Its steam outlet determines the steam output direction and flow rate, ensuring system stability and reliability. The inner wall of the outer tube assembly limits and supports the inner tube assembly. The inner tube assembly ensures smooth steam entry into the steam pipe assembly through a flow channel, and its pipe diameter and other parameters are adapted to the installation channel, avoiding pressure and flow problems. The two work together to form a stable whole. Even if the coffee machine vibrates during operation, the inner tube assembly remains stable, ensuring stable steam transmission and avoiding problems caused by shaking of the inner tube assembly. During use, the inner tube assembly is directly connected to the steam input pipe. When external steam is input, it directly enters the inner tube assembly, reducing the contact area during steam input and reducing condensation. Moreover, the direct steam input to the inner tube assembly results in a shorter steam flow path through the steam output system, with less residual condensation within the system. The steam pipe assembly and tube assembly, when combined, form a compact structure that remains stable under complex operating conditions, ensuring system reliability and durability, reducing equipment maintenance frequency, and improving the performance and economy of the coffee machine.
[0007] In one embodiment, the inner tube assembly includes an inner tube and a limiting component. The inner tube is disposed on the outer tube assembly and located within the mounting channel. The inner tube has the flow channel, and the limiting component is disposed on the outer tube assembly and abuts against the inner tube. The limiting component enhances the inner tube's resistance to displacement within the mounting channel, ensuring that the inner tube remains fixed in the correct position when subjected to external forces such as coffee machine vibration or steam pressure fluctuations. This guarantees the unobstructed and stable flow channel. The cooperation between the inner tube and the limiting component effectively prevents problems such as steam transmission interruption or damage from collisions with other components that may occur due to inner tube movement. This further improves the reliability of the entire steam output system, ensuring that steam can be continuously and smoothly transmitted along the predetermined route and flow rate, meeting the requirements for steam supply stability in coffee making, and guaranteeing the normal operation of the coffee making process.
[0008] In one embodiment, the inner tube includes an inner tube body, an inner tube core, and a tube body limiting member. The inner tube body is sleeved on the inner tube core, and the tube body limiting member is sleeved on the inner tube body. The tube body limiting member abuts against the limiting component, and the inner tube core is provided with the flow passage. The nested fit between the inner tube body, the inner tube core, and the tube body limiting component offers significant advantages in mechanical performance. The inner tube body provides external protection for the inner tube core, enhancing the overall structural strength of the inner tube and enabling it to better withstand the pressure generated when steam flows through the flow channel. This prevents the inner tube core from deforming or cracking due to excessive pressure, ensuring the shape and size of the flow channel remain stable and allowing steam to flow smoothly within it. The tube body limiting component further strengthens the positioning effect of the inner tube within the installation channel, limiting the possibility of displacement from multiple angles. This allows the inner tube to maintain an accurate position even under complex operating environments (such as frequent starts and stops, temperature changes, etc.). During use, this structural fit allows steam to flow continuously and smoothly within a stable flow channel. Even under long-term high-temperature and high-pressure steam environments, it maintains good structural integrity, reducing steam leakage and abnormal flow caused by changes in the inner tube's own structure. This ensures the long-term stable operation of the steam output system and the stability and accuracy of steam supply in coffee making, contributing to the production of consistently high-quality coffee beverages.
[0009] In one embodiment, the inner tube further includes a second sealing ring, which is sleeved on the inner tube body and sandwiched between the inner tube body and the outer tube assembly. The second sealing ring fits tightly with both the inner tube body and the outer tube assembly, and its material possesses good elasticity and sealing performance, accurately filling the minute gaps between the inner tube body and the outer tube assembly to form a reliable sealing structure. During use, it effectively prevents steam leakage from the connection between the inner tube and the outer tube assembly, ensuring that all steam can pass through the flow channel into the subsequent flow path, maintaining stable steam pressure and flow rate within the system. For coffee making, stable steam pressure and flow rate are key factors in producing high-quality coffee beverages. The presence of the second sealing ring guarantees this condition, ensuring a stable and sufficient steam supply during coffee making, thus improving the quality and effect of coffee production.
[0010] In one embodiment, the outer tube assembly includes a tube assembly and an inner core assembly, the inner core assembly being disposed on the tube assembly, the inner core assembly and the tube assembly cooperating to form the installation channel, the tube assembly having the installation opening, and the inner core assembly having the steam outlet. The steam input hose connects to the inner tube sequentially through the installation opening and installation channel. Steam is directly delivered to the inner tube through the steam input hose, effectively preventing excessive condensation of water vapor in the installation opening and installation channel. The installation opening provides a convenient access method for the installation of the steam input hose, and its size is compatible with the inner tube assembly, ensuring a tight and accurate connection. The steam outlet is rationally designed according to the steam output requirements. Its position and opening size match the steam transmission path of the entire system, ensuring that the steam can be discharged smoothly and stably. This effectively copes with the influence of various external forces and temperature changes generated during the operation of the coffee machine, ensuring the integrity of the overall steam output system structure. At the same time, it allows the steam to be smoothly output from the steam outlet along the designed path, meeting the requirements for the steam output position and state in coffee making, providing a stable and suitable steam supply for coffee making, ensuring the smooth progress of coffee making and the quality of the final beverage.
[0011] In one embodiment, the inner core assembly is provided with a mounting groove, a limiting groove, and a vent. The inner tube is located at the mounting groove, the limiting assembly is located at the limiting groove, and the vent communicates with the flow channel. The end of the vent away from the flow channel is the steam outlet. The mounting groove provides an accurate installation position for the inner tube, allowing it to be securely placed inside the inner core assembly. The limiting groove positions the limiting assembly, ensuring that it accurately abuts against the inner tube, further enhancing the connection stability and positional accuracy between the components. The vent connects the flow channel and the steam outlet, ensuring that steam flows smoothly from the inner tube to the steam outlet and is output, making the steam output path continuous and efficient. In use, the cooperation of the above components helps improve coffee making efficiency because stable and smooth steam transmission allows related operations (such as frothing milk) to be completed more quickly, while ensuring that steam is supplied to the corresponding production stages in the appropriate state and flow rate, improving the quality of coffee making and making the taste and appearance of the coffee beverage more in line with requirements.
[0012] In one embodiment, the pipe assembly includes a pipe body, a cover, a limiting cover, and a first sealing ring. The cover is disposed on the pipe body, and a limiting step is formed on the outer wall of the pipe body. The first sealing ring is sleeved on the pipe body and located at the limiting step. The limiting cover is disposed on the pipe body, and a limiting space is formed between the limiting cover and the first sealing ring. The inner core assembly is provided with a locking groove, and the pipe body is adapted to the locking groove. A limiting protrusion is formed on the outer wall of the inner core assembly, and a limiting guide groove is provided on the steam pipe assembly. The limiting protrusion is adapted to the limiting guide groove. The coordination between the internal components of the pipe assembly and with the inner core assembly and steam pipe assembly enhances the connection stability and positioning accuracy of the entire system; the cover provides a certain degree of sealing and protection; the first sealing ring, using its own elasticity to fill the limiting step, effectively prevents steam leakage from the connection between the pipe body and other components. The limiting space formed by the limiting cover and the first sealing ring further stabilizes the installation position of the relevant components, making the internal structure of the pipe body more stable; the fitting installation of the pipe body and the locking groove ensures the tightness and firmness of the connection between the two, preventing loosening due to external factors (such as vibration, temperature changes, etc.); the limiting protrusion and the limiting... The adaptive guide grooves ensure that the steam pipe assembly can be accurately installed and positioned in the corresponding location, guaranteeing the accurate relative positions of each component. During use, the cooperation of the above components ensures that the entire steam output system maintains structural stability even under complex coffee machine operating environments (such as frequent starts, vibrations, temperature changes, etc.), ensuring stable and leak-free steam transmission. Furthermore, the coordinated work of each component can precisely control the direction and flow of steam, providing reliable steam for coffee making, improving the stability and quality of coffee making, and allowing the coffee making process to proceed stably and efficiently, reducing fluctuations in coffee quality caused by steam system problems.
[0013] In one embodiment, the steam pipe assembly is provided with an air inlet channel surrounding the steam channel. The outlet of the steam channel is located within the air inlet channel, and the side wall of the steam pipe assembly has an air inlet communicating with the air inlet channel. This structure achieves effective steam regulation in the final stage of steam output. The connection between the steam pipe assembly and the outer pipe assembly is stable, ensuring its position within the system and enabling accurate reception and subsequent processing of steam from the inner pipe assembly. The design of the air inlet channel surrounding the steam channel allows the inlet air to mix evenly with the steam. The position and size of the air inlet are rationally set according to actual needs, facilitating control of the amount and speed of air inlet. In use, the air inlet channel can introduce an appropriate amount of air as needed, altering the steam state to better suit coffee brewing requirements. For example, when frothing milk, the steam after air inlet can better blend with the milk, producing high-quality milk foam, thereby improving the taste and appearance of the coffee beverage. This provides strong support for producing coffees of different flavors and qualities, meeting consumers' diverse needs for high-quality coffee beverages.
[0014] In one embodiment, the steam pipe assembly includes a steam output pipe, an outer sleeve, a third sealing ring, and a protective ring. The steam output pipe is disposed on the outer pipe assembly and has a steam passage. The outer sleeve is fitted onto the steam output pipe and has an air inlet passage. An air inlet communicating with the air inlet passage is opened on the outer wall of the outer sleeve. The third sealing ring is fitted onto the steam output pipe and sandwiched between the steam output pipe and the outer sleeve. The protective ring is fitted onto the outer sleeve. The aforementioned components work together to create a stable and efficient steam output system that effectively regulates steam conditions. The third sealing ring's excellent sealing performance ensures the air intake channel remains sealed, preventing air leakage from affecting steam regulation. The protective ring, located on the outside of the steam pipe assembly, allows for easier control of force direction and intensity compared to directly manipulating internal components like the steam output pipe, making disassembly smoother. Furthermore, during disassembly, the protective ring, as a relatively independent and easily accessible component, helps to smoothly separate the steam pipe assembly from the outer pipe assembly and other related parts, maintaining the integrity of each component and preventing damage due to improper disassembly. During reinstallation, the protective ring also helps operators more intuitively locate the steam pipe assembly, ensuring accurate reinstallation with the outer pipe. The precise placement of components ensures the accuracy and stability of the entire steam output system structure, guaranteeing its normal operation and providing a stable and reliable steam supply for coffee making. This enhances the convenience and practicality of the coffee machine during daily maintenance and use. The steam output pipe features a straight design, which, compared to a bent pipe, reduces resistance and stabilizes the flow rate of steam. This effectively reduces energy loss when steam contacts the pipe wall, minimizing condensation. Even if some steam condenses into water droplets when passing through the straight pipe at a high speed, it is quickly expelled by the high-speed airflow, preventing accumulation inside the pipe. Furthermore, the straight pipe structure offers higher mechanical strength, better withstanding steam pressure and temperature changes, thus enhancing the system's reliability and stability.

[0032] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention 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.
[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.
[0034] The steam output system and coffee machine of some embodiments of the present invention are described below with reference to the accompanying drawings.
[0035] like Figures 1 to 13 As shown, this embodiment discloses a steam output system, which includes: an outer pipe assembly 1, which has an installation channel 101, an installation opening 102 communicating with the installation channel 101, and a steam outlet 103; an inner pipe assembly 2, which is disposed on the outer pipe assembly 1 and at least partially located within the installation channel 101, and has a flow passage 201 for connecting to a steam input pipe; and a steam pipe assembly 3, which is disposed on the outer pipe assembly 1 and has a steam passage 301, wherein the installation opening 102, the flow passage 201, and the steam passage 301 are sequentially connected.
[0036] This application discloses a steam output system. The outer tube assembly 1 has strength and rigidity, capable of supporting the internal components and withstanding steam transmission pressure. Its steam outlet determines the steam output direction and flow rate, ensuring system stability and reliability. The inner wall of the outer tube assembly 1 limits and supports the inner tube assembly 2. The inner tube assembly 2 ensures smooth steam entry into the steam pipe assembly 3 through the flow channel 201, and its pipe diameter and other parameters are adapted to the installation channel, avoiding pressure and flow problems. The two work together to form a stable whole. Even if the coffee machine vibrates during operation, the inner tube assembly remains stable, ensuring stable steam transmission and avoiding problems caused by shaking of the inner tube assembly. During use, the inner tube assembly 2 is directly connected to the steam input pipe. When external steam is input, it directly enters the inner tube assembly 2, reducing the contact area during steam input and reducing the generation of condensate. Moreover, the direct input of steam into the inner tube assembly 2 results in a shorter steam flow path through the steam output system, leading to less residual condensate within the system. The steam pipe assembly 3 and the outer pipe body assembly 1 are combined to form a compact structure, which can maintain stability under complex working conditions, ensure system reliability and durability, reduce equipment maintenance frequency, and improve the performance and economy of the coffee machine.
[0037] like Figures 1 to 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner tube assembly 2 includes an inner tube 21 and a limiting assembly 22. The inner tube 21 is disposed on the outer tube assembly 1 and located within the installation channel 101. The inner tube 21 has a flow channel 201. The limiting assembly 22 is disposed on the outer tube assembly 1 and abuts against the inner tube 21. The limiting assembly 22 enhances the ability of the inner tube 21 to resist displacement within the installation channel 101, so that the inner tube 21 can be fixed in the correct position when subjected to external forces such as coffee machine vibration or steam pressure fluctuations, ensuring the unobstructed and stable flow channel 201. The cooperation between the inner tube 21 and the limiting assembly 22 effectively prevents problems such as steam transmission interruption or collision damage with other components that may occur due to the movement of the inner tube 21, further improving the reliability of the entire steam output system, ensuring that steam can be continuously and smoothly transmitted along the predetermined route and flow rate, meeting the requirements for steam supply stability in coffee making, and ensuring the normal operation of the coffee making process.
[0038] In addition to the features of the above embodiments, this embodiment further specifies that: the inner tube 21 includes an inner tube body 211, an inner tube core 212 and a tube body limiting member 213, the inner tube body 211 is sleeved on the inner tube core 212, the tube body limiting member 213 is sleeved on the inner tube body 211, the tube body limiting member 213 abuts against the limiting component 22, and the inner tube core 212 is provided with a flow channel 201. The nested fit between the inner tube body 211, the inner tube core 212, and the tube body limiting member 213 has significant advantages in mechanical performance. The inner tube body 211 provides external protection for the inner tube core 212, enhancing the overall structural strength of the inner tube 21 and enabling it to better withstand the pressure generated when steam flows in the flow channel 201. This prevents the inner tube core 212 from deforming or cracking due to excessive pressure, ensuring that the shape and size of the flow channel 201 remain stable and that steam can flow smoothly within it. The tube body limiting member 213 further strengthens the inner tube 21 in the installation channel 10. The positioning effect within the inner tube 21 ensures that it maintains an accurate position even under complex operating conditions (such as frequent starts and stops, temperature changes, etc.). During use, this structural design allows steam to flow continuously and smoothly within the stable flow channel 201. Even under long-term high-temperature and high-pressure steam environments, it maintains good structural integrity, reducing steam leakage and abnormal flow caused by changes in the inner tube 21's own structure. This ensures the long-term stable operation of the steam output system and the stability and accuracy of steam supply in coffee making, contributing to the production of consistently high-quality coffee beverages.
[0039] In addition to the features of the above embodiments, this embodiment further specifies that: the inner tube 21 also includes a second sealing ring 214, which is sleeved on the inner tube body 211 and sandwiched between the inner tube body 211 and the outer tube assembly 1. The second sealing ring 214 fits tightly with the inner tube body 211 and the outer tube assembly 1, and its material has good elasticity and sealing performance, which can accurately fill the tiny gap between the inner tube body 211 and the outer tube assembly 1 to form a reliable sealing structure. During use, it effectively prevents steam from leaking out from the connection between the inner tube 21 and the outer tube assembly 1, ensuring that all steam can enter the subsequent flow path through the flow channel 201, maintaining the stability of steam pressure and flow rate in the system. For coffee making, stable steam pressure and flow rate are one of the key factors in making high-quality coffee drinks. The presence of the second sealing ring 214 ensures this condition, enabling a stable and sufficient steam supply during coffee making, thus improving the quality and effect of coffee making.
[0040] like Figures 1 to 5 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the outer tube assembly 1 includes a tube assembly 11 and an inner core assembly 12, the inner core assembly 12 is disposed on the tube assembly 11, the inner core assembly 12 and the tube assembly 11 cooperate to form an installation channel 101, the tube assembly 11 has an installation opening 102, and the inner core assembly 12 has a steam outlet 103. The steam input hose connects to the inner tube 21 via the installation opening 102 and the installation channel 101. Steam is directly delivered to the inner tube 21 through the steam input hose, effectively preventing the excessive condensation of water vapor in the installation opening 102 and the installation channel 101. The installation opening 102 provides a convenient access for the installation of the steam input hose, and its size is compatible with the inner tube assembly 2, ensuring a tight and accurate connection. The steam outlet 103 is rationally designed according to the steam output requirements. Its position and opening size are consistent with the steam transmission path of the entire system, ensuring that the steam can be discharged smoothly and stably. This effectively copes with the influence of various external forces and temperature changes generated during the operation of the coffee machine, ensuring the integrity of the overall structure of the steam output system. At the same time, it allows the steam to be output smoothly from the steam outlet 103 along the designed path, meeting the requirements for the steam output position and state in coffee making, providing a stable and suitable steam supply for coffee making, and ensuring the smooth progress of coffee making and the quality of the final beverage.
[0041] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 12 and Figure 13As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner core assembly 12 is provided with an installation groove 1201, a limiting groove 1202 and an exhaust hole 1203, the inner tube 21 is located at the installation groove 1201, the limiting assembly 22 is located at the limiting groove 1202, the exhaust hole 1203 is connected to the flow channel 201, and the end of the exhaust hole 1203 away from the flow channel 201 is the steam outlet 103. The mounting slot 1201 provides an accurate mounting position for the inner tube 21, allowing it to be securely placed inside the inner core assembly 12. The limiting slot 1202 positions the limiting assembly 22, ensuring that the limiting assembly 22 accurately abuts against the inner tube 21, further enhancing the connection stability and positional accuracy between the components. The exhaust port 1203 connects the flow channel 201 to the steam outlet 103, ensuring that steam can flow smoothly from the inner tube 21 to the steam outlet 103 and be output, making the steam output path continuous and efficient. In use, the cooperation of the above components helps to improve coffee making efficiency, because stable and smooth steam transmission allows related operations (such as frothing milk) to be completed more quickly, while ensuring that steam is supplied to the corresponding production stages in the appropriate state and flow rate, improving the quality of coffee making, and making the taste and appearance of the coffee beverage more in line with requirements.
[0042] like Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 10 , Figure 12 and Figure 13As shown, in addition to the features of the above embodiments, this embodiment further defines: the pipe assembly 11 includes a pipe body 111, a cover 112, a limiting cover 113, and a first sealing ring 114. The cover 112 is disposed on the pipe body 111, and a limiting step is formed on the outer wall of the pipe body 111. The first sealing ring 114 is sleeved on the pipe body 111 and located at the limiting step. The limiting cover 113 is disposed on the pipe body 111, and a limiting space is formed between the limiting cover 113 and the first sealing ring 114. The inner core assembly 12 is provided with a locking groove 1204, and the pipe body 111 is adapted to the locking groove 1204. A limiting protrusion 121 is formed on the outer wall of the inner core assembly 12, and a limiting guide groove 304 is provided on the steam pipe assembly 3. The limiting protrusion 121 is adapted to the limiting guide groove 304. The cooperation between the internal components of the pipe body assembly 11 and with the inner core assembly 12 and steam pipe assembly 3 enhances the connection stability and positioning accuracy of the entire system; the cover 112 provides a certain degree of sealing and protection; the first sealing ring 114, using its own elasticity to fill the limiting step, effectively prevents steam leakage from the connection between the pipe body 111 and other components; the limiting space formed by the limiting cover 113 and the first sealing ring 114 further stabilizes the installation position of the relevant components, making the internal structure of the pipe body 111 more stable; the fitting installation of the pipe body 111 and the locking groove 1204 ensures the tightness and firmness of the connection between the two, and will not be affected by external factors (such as vibration, temperature changes, etc.). The fit between the limiting protrusion 121 and the limiting guide groove 304 ensures that the steam pipe assembly 3 can be accurately installed and positioned in the corresponding position, ensuring that the relative positions between the components are accurate. During use, the cooperation of the above components ensures that the entire steam output system can maintain structural stability in complex coffee machine operating environments (such as frequent starts, vibration, temperature changes, etc.), ensuring stable steam transmission without leakage. Furthermore, the coordinated work of each component can precisely control the direction and flow of steam, providing reliable steam for coffee making, improving the stability and quality of coffee making, and allowing the coffee making process to proceed stably and efficiently, reducing fluctuations in coffee quality caused by steam system problems.
[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the steam pipe assembly 3 is provided with an air supply channel 302, the air supply channel 302 surrounds the steam channel 301, the outlet of the steam channel 301 is located in the air supply channel 302, and the side wall of the steam pipe assembly 3 is provided with an air supply inlet 303 communicating with the air supply channel 302. The connection between the steam pipe assembly 3 and the outer pipe assembly 1 is secure, ensuring its stable position within the system and enabling it to accurately receive steam from the inner pipe assembly 21 for subsequent processing. The design of the air inlet channel 302 surrounding the steam channel 301 allows the introduced air to mix evenly with the steam. The position and size of the air inlet 303 are rationally set according to actual needs, facilitating control of the amount and speed of air intake. During use, the air inlet channel 302 can introduce an appropriate amount of air as needed, changing the state of the steam to better suit the requirements of coffee making. For example, when frothing milk to make milk foam, the steam after adding air can better blend with the milk, producing high-quality milk foam, thereby improving the taste and appearance of the coffee beverage. This provides strong support for making coffee with different flavors and qualities, meeting consumers' diverse needs for high-quality coffee beverages.
[0044] In addition to the features of the above embodiments, this embodiment further specifies that: the steam pipe assembly 3 includes a steam output pipe 31, an outer sleeve 32, a third sealing ring 33, and a protective ring 34. The steam output pipe 31 is disposed on the outer pipe assembly 1 and has a steam channel 301. The outer sleeve 32 is sleeved on the steam output pipe 31 and has an air inlet channel 302. The outer wall of the outer sleeve 32 has an air inlet 303 communicating with the air inlet channel 302. The third sealing ring 33 is sleeved on the steam output pipe 31 and sandwiched between the steam output pipe 31 and the outer sleeve 32. The protective ring 34 is sleeved on the steam output pipe 31. The excellent sealing performance of the third sealing ring 33 ensures the airtightness of the air intake channel 302, preventing air leakage from affecting the steam regulation effect. The protective ring 34 is located on the outside of the steam pipe assembly 3. Compared with directly operating on internal components such as the steam output pipe 31, holding the protective ring 34 makes it easier to control the direction and force of the force, making the disassembly process smoother. At the same time, during disassembly, the protective ring 34, as a relatively independent and easy-to-grip component, can help to smoothly separate the steam pipe assembly 3 from the outer pipe assembly 1 and other related components, helping to maintain the integrity of each component and avoid damage to components due to improper disassembly. During reinstallation, the protective ring 34 can also help the operator to more intuitively locate the position of the steam pipe assembly 3, so that it can be accurately installed back into the position that matches the outer pipe assembly 1 and other components. The design ensures the accuracy and stability of the entire steam output system structure, thereby guaranteeing the normal operation of the subsequent steam output system and continuously providing a stable and reliable steam supply for coffee making. This enhances the convenience and practicality of the entire coffee machine in daily maintenance and use. The steam output pipe 31 adopts a straight pipe design. Compared with the bent pipe structure, the straight pipe design results in less resistance to steam flow and a more stable flow rate. It can effectively reduce energy loss when steam comes into contact with the pipe wall, thereby reducing the occurrence of condensation. When steam passes through the straight pipe at a high speed, even if some steam condenses into water droplets, it will be quickly discharged from the pipe under the propulsion of the high-speed airflow, making it less likely to accumulate inside the pipe.
