Description

Technical Field

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

[0002] In existing technology, coffee machines lack a pour-over mechanism, making them unable to flexibly adapt to the rapid brewing needs of different scenarios. When a user needs to make coffee with different flavor preferences for multiple guests, a pour-over mechanism can quickly adjust the water flow and temperature. However, coffee machines lacking this mechanism can only rely on preset programs and cannot make timely adjustments, resulting in low brewing efficiency. Utility Model Content

[0003] Therefore, it is necessary to address the lack of a pour-over mechanism in coffee machines by providing a pour-over mechanism and a coffee machine.

[0004] A hand-operated flushing structure includes: a support assembly having an installation space; a housing assembly detachably mounted on the support assembly with its connection point located in the installation space; a water inlet assembly having a liquid passage chamber, the water inlet assembly having an inlet and an outlet communicating with the liquid passage chamber, the inlet, the liquid passage chamber, and the outlet being sequentially connected, the housing assembly being sleeved on the water inlet assembly; and a control assembly mounted on the water inlet assembly for electrical connection with a valve body.

[0005] The above discloses a pour-over structure for coffee machines. Currently available brewers do not employ this pour-over structure, resulting in insufficient precision and flexibility in liquid control. This pour-over structure overcomes this deficiency through a unique component design. The support assembly provides a stable foundation and reasonable layout for each component, while the outer shell assembly is supported within this space. The support assembly protects and supports the outer shell assembly, ensuring stable operation of the water inlet assembly and other components. The inlet, passage chamber, and outlet of the water inlet assembly are sequentially connected, forming a smooth liquid transmission path and ensuring high efficiency in the brewing process. Crucially, the control component is located on the water inlet assembly, and a solenoid valve is installed between the pour-over structure and the heating assembly. The control component allows for precise control of the solenoid valve's on / off state. This design allows users to precisely adjust the opening and closing of the solenoid valve according to actual needs, thereby controlling the timing and flow rate of liquid flowing from the heating assembly into the pour-over structure, achieving refined control of the brewing process. Adjusting the brew concentration or controlling the brewing speed can be easily achieved. At the same time, this precise control can effectively avoid liquid waste, improve resource utilization, enhance the energy efficiency and environmental friendliness of the equipment, and bring users a more convenient, efficient and personalized brewing experience. Compared with existing brewers, it has achieved a qualitative leap in functionality and practicality.

[0006] In one embodiment, the water inlet assembly includes an input section and an output section. The output section is disposed on the input section, and the control component is disposed on the input section. The input section has a liquid inlet, and the output section has a liquid outlet. The input section or the output section is disposed on the housing assembly. By disposing the input section or the output section on the housing assembly and the output section on the input section, the input section has a liquid inlet and is connected to the heating component, serving as the initial port for liquid input and providing a stable liquid source for the hand-pour structure. The control component, disposed on the input section, can regulate the liquid inflow in real time, such as controlling the start and stop of liquid inflow through a solenoid valve switch, achieving precise liquid input control. The output section, disposed on the input section and having a liquid outlet, serves as the liquid output port, allowing the liquid from the input section to be output to the user's cup. Its connection design with the input section ensures a smooth liquid flow path, reducing transmission resistance and pressure loss. The placement of the input section or the output section on the housing assembly provides stable support for the water inlet assembly, ensuring its positional stability during system operation and preventing problems such as loosening of the interface and liquid leakage due to vibration or external forces.

[0007] In one embodiment, the water inlet assembly includes a liquid inlet, a liquid passage, and a liquid outlet. The liquid passage is disposed on the outer casing assembly. The liquid inlet and the liquid outlet are located on the liquid passage and at its two ends. The control assembly is disposed on the liquid inlet. The liquid inlet has a liquid inlet. The liquid passage and the liquid outlet cooperate to form a liquid passage chamber. The liquid outlet has a liquid outlet. By combining the liquid inlet, liquid passage, and liquid outlet, different stages and functional areas of liquid flow are clearly defined. The liquid inlet, disposed on the liquid passage and equipped with a liquid inlet and control assembly, not only facilitates the introduction of liquid but also allows for precise control of the liquid inflow through the control assembly's precise operation of the solenoid valve, laying the foundation for subsequent brewing processes. The liquid passage, with its liquid passage chamber mounted on the outer casing assembly, serves as the core channel for liquid transmission. The liquid outlet, located at the other end of the liquid conveying component, is responsible for smoothly discharging the brewed liquid. Its structural design ensures the stability and controllability of the liquid flow, preventing splashing or uneven flow. These three components work together to form a complete and efficient liquid transfer and control system, supported and protected by the bracket and housing components.

[0008] In one embodiment, the liquid inlet component includes an inlet housing and an inlet pipe. The inlet housing is disposed at one end of the liquid-passing component, and the inlet pipe passes through the inlet housing and connects to the liquid-passing component. The control component is disposed on the inlet housing, and the inlet pipe has the inlet port. By installing the inlet housing at one end of the liquid-passing component, a stable installation base is provided, serving as a connection transition and protection function, firmly connecting the inlet and liquid-passing components, and protecting the liquid from external environmental interference during liquid flow. The inlet pipe passes through the inlet housing, and the inlet port on it serves as the inlet for the liquid to enter the water inlet component, ensuring precise liquid flow. The control components are respectively arranged on the side walls of the inlet housing and the inlet pipe. This distribution method enables flexible and precise control of the liquid inlet process. The portion disposed on the inlet housing facilitates connection with external control signals or operating components to receive control commands; while the portion located on the side wall of the inlet pipe, in conjunction with a solenoid valve, quickly responds to control commands and precisely adjusts the liquid flow rate at the inlet port. Working together, the two can ensure the stability of liquid introduction and enable precise control of the liquid supply process, making the hand-pumped equipment more intelligent and efficient in the liquid supply stage.

[0009] In one embodiment, the liquid-passing component includes a liquid-passing component body and a connector. The liquid-passing component body is disposed on the housing assembly, and the connector is disposed on the liquid-passing component body. The connector is located in the liquid inlet component and connected to the liquid inlet pipe, and the liquid outlet component is disposed on the liquid-passing component body. By placing the liquid-passing component body on the housing assembly, a stable support is provided for the entire liquid-passing system, and the stable operation is ensured by the protection of the housing assembly. The connector is disposed on the liquid-passing component body, located in the liquid inlet component, and communicates with the liquid inlet. This design achieves precise docking between the liquid inlet component and the liquid-passing component, ensuring that the liquid flows smoothly into the liquid-passing cavity of the liquid-passing component body and effectively preventing liquid leakage. The liquid outlet component is disposed on the liquid-passing component body. The three components work together to form a smooth liquid transmission channel. The liquid-passing component adopts a structural design in which the connector and the liquid-passing component body are integrally formed, eliminating the assembly gaps of the traditional split structure, significantly improving structural strength and sealing performance, avoiding liquid leakage, and enhancing resistance to deformation. Meanwhile, the one-piece molding process simplifies the production process and reduces assembly errors, while also reducing the number of vulnerable parts and improving product reliability and ease of maintenance.

[0010] In one embodiment, the liquid outlet includes a liquid outlet body and a liquid outlet pipe. The liquid outlet body is disposed on the liquid conveying component, and the liquid outlet pipe is disposed on the liquid outlet body, with the liquid outlet port provided in the liquid outlet pipe. By securely mounting the liquid outlet body on the liquid conveying component, it acts as a connecting hub, ensuring a seamless connection between the liquid conveying chamber and the liquid outlet pipe, effectively reducing liquid transmission resistance and pressure loss, and ensuring smooth liquid flow. The liquid outlet pipe is installed on the liquid outlet body, and its liquid outlet port serves as the final liquid output end, enabling the liquid to be output smoothly.

[0011] In one embodiment, the outer casing assembly includes an outer casing body and a fastener. The fastener is disposed on the outer casing body and is adapted to the installation space. The outer casing body is fitted onto the water inlet assembly. This combination of the outer casing body and the fastener plays a crucial supporting, protective, and integrating role in the entire hand-pump structure. The fastener, located on the outer casing body, allows for stable installation within the mounting space of the support assembly. This connection method not only ensures the stability of the outer casing assembly during use but also provides a reliable load-bearing foundation for the internal water inlet assembly, preventing vibration or displacement from affecting the dispensing effect. Simultaneously, the synergistic effect of the fastener and the outer casing body tightly encloses the water inlet assembly, forming a physical protective barrier that effectively prevents the intrusion of external dust, moisture, and other impurities, protecting the structure of the water inlet assembly and extending its service life. Furthermore, this enclosed design helps integrate the various components, making the overall hand-pump structure layout more compact and rational, reducing the exposure of external pipes or components, and lowering safety hazards during use. Meanwhile, the integrated design of the outer shell and the fastener eliminates the assembly gaps of traditional split structures, significantly enhancing the overall rigidity and stability of the outer shell assembly. This allows it to be more securely installed in the mounting space of the bracket assembly, resisting external impacts and vibrations during use, and effectively preventing structural loosening from affecting the normal operation of the water inlet assembly.

[0012] In one embodiment, the liquid inlet housing has a wire hole through which the signal wire passes, and after passing through the wire hole, the signal wire is electrically connected to the control component. By placing the signal wire 5 on the wire hole of the liquid inlet housing 311 and simultaneously electrically connecting it to the control component 4, the user can easily operate the signal wire, greatly improving ease of use. The user can quickly issue opening and closing commands by simply pressing the control component 4, achieving intuitive control of the liquid inlet process. The two components work together to enable the control component 4 not only to flexibly control the opening and closing of the valve body between the hand-operated structure and the heating component, but also to enhance the human-machine interface and operational stability of the entire hand-operated structure. At the same time, this layout also facilitates equipment maintenance and repair. If a signal transmission failure occurs, the signal wire or control button can be quickly located for troubleshooting, reducing equipment maintenance costs and difficulty.

[0013] In one embodiment, the support assembly includes a support member and a mounting member. The support member is disposed on the mounting member and is used for mounting on an external structure. The outer casing assembly is detachably disposed on the mounting member, and the mounting member has the mounting space. By disposing the support member on the mounting member, it acts as a connecting bridge between the hand-pump structure and the external structure. Fixing it to the external structure provides a stable support point for the entire hand-pump structure, ensuring that the equipment will not shift due to external impacts or vibrations caused by liquid flow during use. The mounting space of the mounting member provides precise installation space for the outer casing assembly and the water inlet assembly. Through reasonable size design and structural layout, mutual interference between components during operation can be effectively avoided, ensuring the smoothness of the liquid transmission path. Simultaneously, the tight fit between the mounting member and the outer casing assembly enhances the stability of the overall structure, protects the internal components, and further improves the reliability of the equipment. Meanwhile, the integrated molding of the support and mounting components completely eliminates the connection gaps and assembly errors inherent in traditional split structures. This creates a seamless whole without weak points, significantly improving the structural rigidity of the bracket assembly. It effectively prevents deformation or breakage caused by stress concentration, ensuring the entire hand-punched structure is stably installed without wobbling. Furthermore, this design simplifies the production process, eliminating the welding and bolting assembly steps required for split structures. This not only reduces production costs but also minimizes quality risks caused by assembly processes, improving product consistency.

[0014] In one embodiment, a sealing assembly is further included, comprising a first sealing assembly and a second sealing assembly. The first sealing assembly is sandwiched in the connection gap between the liquid inlet and the liquid outlet, and the second sealing assembly is sandwiched in the connection gap between the liquid outlet and the liquid outlet. This dual-protection design of the first and second sealing assemblies provides reliable sealing for the liquid transfer system of the hand-pour structure, effectively improving the performance and service life of the equipment. The first sealing assembly, sandwiched in the connection gap between the liquid inlet and the liquid outlet, tightly fills the gap at the joint, preventing liquid leakage from the interface under pressure, ensuring the stability and sealing of the liquid transfer process, and avoiding material waste due to liquid leakage. The second sealing assembly, located in the connection gap between the liquid outlet and the liquid outlet, also forms a solid sealing barrier, ensuring that the brewed liquid flows out along a predetermined path, preventing liquid overflow from affecting the operating environment and operational safety. The two work together to achieve a comprehensive seal on the key connection parts of the water inlet component, effectively reducing pressure loss caused by poor sealing, ensuring stable liquid transmission in the inlet, flow and outlet stages, and thus improving the consistency of the brewing effect. At the same time, the good sealing performance can also prevent external dust and impurities from entering the water inlet component, reducing the risk of blockage, reducing maintenance frequency, extending the service life of the equipment, and bringing users a more efficient, clean and stable user experience.

[0015] The second aspect of this application discloses a coffee machine, which includes: the above-described hand-drip structure; a boiler assembly; a valve body; a control board electrically connected to the valve body; and a coffee machine body, wherein the boiler assembly, the valve body, and the support assembly are disposed on the coffee machine body, the boiler assembly, the valve body, and the liquid inlet are connected in sequence, and the control assembly is electrically connected to the control board.

[0016] The second aspect disclosed above discloses a brewing machine in which a support assembly serves as the core support structure, securely mounted on the brewing machine body. This provides a solid and reliable foundation for the outer shell assembly and water inlet assembly, ensuring stable operation of each component during brewing and preventing displacement due to vibration or external forces, thus guaranteeing the accuracy of the liquid transmission path. Simultaneously, the connection between the liquid inlet and the heating assembly creates an efficient liquid pretreatment channel. A control assembly controls a solenoid valve, allowing the heated liquid to pass through the liquid inlet, the liquid passage chamber, and finally to the liquid outlet, achieving a continuous and controllable brewing process.

Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0037] The following describes some embodiments of the pour-over structure and coffee machine of this utility model with reference to the accompanying drawings.

[0038] Example 1

[0039] like Figures 1 to 11 As shown, this embodiment discloses a hand-operated flushing structure, including: a support assembly 1, which has an installation space 101; a housing assembly 2, which is detachably mounted on the support assembly 1 and the connection is located at the installation space 101; a water inlet assembly 3, which has a liquid passage chamber 302, and has an inlet port 301 and an outlet port 303 communicating with the liquid passage chamber 302, the inlet port 301, the liquid passage chamber 302 and the outlet port 303 being connected in sequence, and the housing assembly 2 being sleeved on the water inlet assembly 3; and a control assembly 4, which is mounted on the water inlet assembly 3 and is used for electrical connection with the valve body.

[0040] This application discloses a pour-over structure for coffee machines. Currently available brewers do not employ this pour-over structure, resulting in insufficient precision and flexibility in liquid control. This pour-over structure overcomes this deficiency through a unique component design. The mounting space 101 of the support assembly 1 provides a stable foundation and reasonable layout space for each component. The outer shell assembly 2 is supported at the mounting space 101, and the support assembly 1 provides protection and support for the outer shell assembly 2, ensuring stable operation of the water inlet assembly 3 and other components. The inlet 301, liquid passage chamber 302, and outlet 303 of the water inlet assembly 3 are sequentially connected, forming a smooth liquid transmission path and ensuring high efficiency in the brewing process. Crucially, the control assembly 4 is located on the water inlet assembly 3, and a solenoid valve is installed between the pour-over structure and the heating assembly. The control assembly 4 allows for precise control of the solenoid valve's opening and closing. This design allows users to precisely adjust the opening and closing of the solenoid valve according to actual needs, thereby controlling the timing and flow rate of liquid flowing from the heating assembly into the pour-over structure, achieving refined control of the brewing process. Adjusting the brewing concentration or controlling the brewing speed can be easily achieved. At the same time, this precise control can effectively avoid liquid waste, improve resource utilization, enhance the energy efficiency and environmental friendliness of the equipment, and bring users a more convenient, efficient and personalized brewing experience. Compared with existing brewers, it has achieved a qualitative leap in functionality and practicality.

[0041] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the water inlet assembly 3 includes an input part and an output part, the output part is disposed on the input part, the control assembly 4 is disposed on the input part, the input part is provided with the liquid inlet 301, the output part is provided with the liquid outlet 303, and the input part or the output part is disposed on the outer shell assembly 2. By placing the input or output section on the housing assembly 2 and the output section on the input section, the input section has a liquid inlet 301 connected to the heating assembly, serving as the initial port for liquid input and providing a stable liquid source for the hand-pour structure. The control assembly 4 is placed on the input section and can regulate the liquid inflow status in real time, such as controlling the start and stop of liquid input through a solenoid valve switch, to achieve precise liquid input control. The output section is placed on the input section and has a liquid outlet 303, serving as the liquid output port, which can output the liquid from the input section to the user's cup. Its connection design with the input section ensures the smoothness of the liquid flow path and reduces transmission resistance and pressure loss. The placement of the input or output section on the housing assembly 2 allows the water inlet assembly 3 to obtain stable support through the housing assembly 2, ensuring its positional stability during system operation and avoiding problems such as loosening of the interface and liquid leakage caused by vibration or external force.

[0042] like Figure 2 , Figure 3 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water inlet assembly 3 includes a liquid inlet 31, a liquid passage 32, and a liquid outlet 33. The liquid passage 32 is disposed on the outer shell assembly 2. The liquid inlet 31 and the liquid outlet 33 are disposed on the liquid passage 32 and located at both ends of the liquid passage 32. The control assembly 4 is disposed on the liquid inlet 31. The liquid inlet 31 has a liquid inlet 301. The liquid passage 32 and the liquid outlet 33 cooperate to form a liquid passage chamber 302. The liquid outlet 33 has a liquid outlet 303. By combining the liquid inlet 31, the liquid passage 32, and the liquid outlet 33, different stages and functional areas of liquid flow are clearly defined. The liquid inlet 31 is disposed on the liquid passage 32 and has a liquid inlet 301 and the control assembly 4. This not only facilitates the introduction of liquid but also allows for precise control of the liquid inflow through the control assembly 4 by accurately operating the solenoid valve, laying the foundation for the subsequent brewing process. The liquid conveying component 32 is equipped with a liquid conveying chamber 302, which is mounted on the housing assembly 2 and serves as the core channel for liquid transfer. The liquid outlet component 33 has a liquid outlet 303, located at the other end of the liquid conveying component 33, responsible for smoothly exporting the brewed liquid. Its structural design ensures the stability and controllability of the liquid flow, avoiding liquid splashing or uneven flow rate. The three components work together to form a complete and efficient liquid transfer and control system for the water inlet assembly 3, supported and protected by the bracket assembly 1 and the housing assembly 2.

[0043] like Figure 3 , Figure 7 , Figure 10 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the liquid inlet component 31 includes a liquid inlet housing 311 and a liquid inlet pipe 312. The liquid inlet housing 311 is disposed at one end of the liquid passing component 32, and the liquid inlet pipe 312 passes through the liquid inlet housing 311 and is connected to the liquid passing component 32. The control component 4 is disposed on the liquid inlet housing 311, and the liquid inlet pipe 312 is provided with a liquid inlet 301. By installing the liquid inlet housing 312 at one end of the liquid passing component 32, a stable installation base is provided, which serves as a connection transition and protection function, firmly connecting the liquid inlet component 31 and the liquid passing component 32, while protecting the liquid from external environmental interference during liquid flow. The liquid inlet pipe 312 passes through the liquid inlet housing 311, and the liquid inlet 301 disposed on it serves as the inlet for the liquid to enter the water inlet component 3, ensuring that the liquid can flow in accurately. The control component 4 is respectively arranged on the side walls of the liquid inlet housing 311 and the liquid inlet pipe 312. This distribution method realizes flexible and precise control of the liquid inlet process. The portion located on the liquid inlet housing 311 facilitates connection to external control signals or operating components to receive control commands; while the portion located on the side wall of the liquid inlet pipe 312, in conjunction with a solenoid valve, quickly responds to control commands and precisely regulates the liquid flow rate. Working together, these two components ensure the stability of liquid introduction and enable precise control of the liquid inlet process, making the hand-operated flushing equipment more intelligent and efficient in the liquid supply stage.

[0044] like Figure 3 , Figure 7 Figure 10 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further defines: the liquid-passing component 32 includes a liquid-passing component body 321 and a connector 322. The liquid-passing component body 321 is disposed on the outer shell assembly 2, and the connector 322 is disposed on the liquid-passing component body 321. The connector 322 is located in the liquid inlet component 31 and connected to the liquid inlet pipe 312. The liquid outlet component 33 is disposed on the liquid-passing component body 321. By disposing the liquid-passing component body 321 on the outer shell assembly 2, a stable support is provided for the entire liquid-passing system. Relying on the protection of the outer shell assembly 2, its stable operation is ensured. The connector 322 is disposed on the liquid-passing component body 321, located in the liquid inlet component 31 and connected to the liquid inlet 301. This design achieves precise docking between the liquid inlet component 31 and the liquid-passing component 32, which can ensure that the liquid flows smoothly into the liquid-passing chamber 302 of the liquid-passing component body 321 and effectively prevent liquid leakage. The liquid outlet component 32 is disposed on the liquid-passing component body 321. The three components cooperate with each other to form a smooth liquid transmission channel. The liquid-passing component 32 adopts a structural design in which the connector 322 and the liquid-passing component body 321 are integrally formed, eliminating the assembly gaps of the traditional split structure, significantly improving structural strength and sealing performance, preventing liquid leakage and enhancing resistance to deformation. At the same time, the integral molding process simplifies the production process and reduces assembly errors, while reducing the number of vulnerable parts, improving product reliability and ease of maintenance.

[0045] like Figure 3 , Figure 7 Figure 10 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the liquid outlet 33 includes a liquid outlet body 331 and a liquid outlet pipe 332. The liquid outlet body 331 is disposed on the liquid conveying component 32, and the liquid outlet pipe 332 is disposed on the liquid outlet body 331. The liquid outlet pipe 332 is provided with a liquid outlet 303. By firmly disposing the liquid outlet body 331 on the liquid conveying component 32, it acts as a connecting hub, ensuring a seamless connection between the liquid conveying chamber 302 and the liquid outlet pipe 332, effectively reducing liquid transmission resistance and pressure loss, and ensuring smooth liquid flow. The liquid outlet pipe 332 is installed on the liquid outlet body 331, and its liquid outlet 303 serves as the final liquid output end, enabling the liquid to be output smoothly.

[0046] like Figure 2 , Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further defines: the outer casing assembly 2 includes an outer casing body 21 and a fixing member 22. The fixing member 22 is disposed on the outer casing body 21 and is adapted to the installation space 101. The outer casing body 21 is fitted onto the water inlet assembly 3. By adopting the combined design of the outer casing body 21 and the fixing member 22, they play a key supporting, protective, and integrating role in the entire hand-pump structure. The fixing member 22 is disposed on the outer casing body 21, so that it can be stably installed in the installation space 101 of the bracket assembly 1. Through this connection method, not only is the stability of the outer casing assembly 2 ensured during use, but it also provides a reliable bearing foundation for the internal water inlet assembly 3, preventing the liquid output effect from being affected by shaking or displacement. At the same time, the synergistic effect of the fixing member 22 and the outer casing body 21 tightly wraps the water inlet assembly 3, forming a physical protective barrier, effectively preventing the intrusion of external dust, water vapor, and other impurities, protecting the structure of the water inlet assembly 3, and extending its service life. Furthermore, this enclosed design helps integrate the various components, making the overall layout of the hand-pump structure more compact and reasonable, reducing the exposure of external pipes or components, and lowering safety hazards during use. At the same time, the integrated design of the outer shell 21 and the fixing component 22 eliminates the assembly gaps of traditional split structures, significantly enhancing the overall rigidity and stability of the outer shell assembly 2. This allows it to be more securely installed within the mounting space 101 of the bracket assembly 1, resisting external impacts and vibrations during use, and effectively preventing structural loosening from affecting the normal operation of the water inlet assembly 3.

[0047] like Figure 2 , Figure 6 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further includes a signal line 5. The liquid inlet housing 311 has a wire hole through which the signal line 5 passes, and the signal line 5 is electrically connected to the control component 4 after passing through the wire hole. By placing the signal line 5 on the wire hole of the liquid inlet housing 311 and simultaneously electrically connecting it to the control component 4, the user can easily operate the signal line, greatly improving ease of use. The user can quickly issue opening and closing commands by simply pressing the control component 4, achieving intuitive control of the liquid inlet process. The two components work together, enabling the control component 4 not only to flexibly control the opening and closing of the valve body between the hand-operated structure and the heating component, but also enhancing the human-machine interface and operational stability of the entire hand-operated structure. At the same time, this layout also facilitates equipment maintenance and repair. If a signal transmission failure occurs, the signal line or control button can be quickly located for troubleshooting, reducing equipment maintenance costs and difficulty.

[0048] like Figure 1 , Figure 2 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines: the support assembly 1 includes a support member 11 and a mounting member 12. The support member 11 is disposed on the mounting member 12 and is used for mounting on the external structure. The outer shell assembly 2 is detachably disposed on the mounting member 12, and the mounting member 12 is provided with an installation space 101. By disposing the support member 11 on the mounting member 12, it serves as a connecting bridge between the hand-pump structure and the external structure. Through fixation with the external structure, it provides a stable force point for the entire hand-pump structure, ensuring that the equipment will not be displaced due to external force collisions or vibrations caused by liquid flow during use. The installation space 101 of the mounting member 12 provides precise installation space for the outer shell assembly 2 and the water inlet assembly 3. Through reasonable size design and structural layout, mutual interference between components during operation can be effectively avoided, ensuring the smoothness of the liquid transmission path. At the same time, the close cooperation between the mounting member 12 and the outer shell assembly 2 enhances the stability of the overall structure, protects the internal components, and further improves the reliability of the equipment. Meanwhile, the integral molding of the support component 11 and the mounting component 12 completely eliminates the connection gaps and assembly errors of traditional split structures, making the support component 11 and the mounting component 12 form a whole without weak points. This significantly improves the structural rigidity of the bracket assembly 1, effectively preventing deformation or breakage caused by stress concentration, and ensuring that the entire hand-punched structure is stably installed without shaking. At the same time, this design simplifies the production process, eliminating the welding, bolting and other assembly processes required for split structures. This not only reduces production costs but also reduces quality risks caused by assembly processes, improving product consistency.

[0049] like Figure 3 , Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further includes a sealing component 6, which comprises a first sealing component 61 and a second sealing component 62. The first sealing component 61 is sandwiched in the connection gap between the liquid inlet 31 and the liquid outlet 32, and the second sealing component 62 is sandwiched in the connection gap between the liquid outlet 32 ​​and the liquid outlet 33. By utilizing the dual protection design of the first sealing component 61 and the second sealing component 62, a reliable sealing guarantee is provided for the liquid transfer system of the hand-pump structure, effectively improving the performance and service life of the equipment. The first sealing component 61, sandwiched in the connection gap between the liquid inlet 31 and the liquid outlet 32, can tightly fill the gap at the joint between the two, preventing liquid from leaking from the interface under pressure, ensuring the stability and sealing of the liquid transfer process, and avoiding material waste due to liquid leakage; the second sealing component 62 is set in the connection gap between the liquid outlet 32 ​​and the liquid outlet 33, which can also form a solid sealing barrier, ensuring that the liquid after brewing can flow out along the predetermined path, avoiding liquid overflow from affecting the use environment and operational safety. The two work together to achieve a comprehensive seal on the key connection parts of the water inlet component 3, effectively reducing pressure loss caused by poor sealing, ensuring stable liquid transmission in the inlet, flow and outlet stages, and thus improving the consistency of the brewing effect. At the same time, the good sealing performance can also prevent external dust and impurities from entering the interior of the water inlet component 3, reducing the risk of blockage, reducing maintenance frequency, extending the service life of the equipment, and bringing users a more efficient, clean and stable user experience.
