Description

Technical Field

[0001] This utility model relates to the field of coffee brewing, and in particular to a liquid supply system and a coffee machine. Background Technology

[0002] In today's diversified coffee culture, pour-over coffee, with its unique flavor profile and personalized brewing experience, has become a favorite among many coffee lovers. However, automatic coffee machines, the mainstay of modern coffee making, generally have the limitation of not being able to brew pour-over coffee, a problem that is becoming increasingly prominent in a market environment where consumer demands are becoming increasingly segmented. Utility Model Content

[0003] Therefore, it is necessary to provide a liquid supply system and a coffee machine to address the problem that coffee machines cannot brew pour-over coffee.

[0004] A liquid supply system for a coffee machine includes: a housing assembly; a pour-over assembly detachably mounted on the housing assembly; a sensor; a sensor, one of which is mounted on the housing assembly and the other on the pour-over assembly, the sensor being matched with the sensor; and a liquid supply assembly electrically connected to the sensor and connected to the pour-over assembly.

[0005] The liquid supply system disclosed in this application provides a stable installation foundation and structural support for the entire system, ensuring that each component maintains a relatively fixed position during the operation of the coffee machine and guaranteeing the stability of the system. The pour-over assembly is detachably mounted on the housing assembly. This detachable design facilitates user operation and meets the needs of different usage scenarios, improving the convenience and flexibility of the coffee machine. One sensor and one induction element are mounted on the pour-over assembly, while the other is mounted on the housing assembly, with the sensor and induction element matched. Through the cooperation of the induction element and induction element, accurate detection of the pour-over assembly's installation status can be achieved. When the pour-over assembly is correctly installed on the housing assembly, the sensor detects the induction element, causing the liquid supply assembly to stop working. If the pour-over assembly is not properly installed or the sensor cannot detect the induction element, the liquid supply assembly starts working, facilitating manual coffee brewing and meeting more usage scenarios. The liquid supply assembly is electrically connected to the sensor and also connected to the pour-over assembly, enabling the liquid supply assembly to control the liquid supply based on the sensor's detection signal. When the pour-over unit is removed, it can be preheated, and the liquid supply unit supplies liquid to the pour-over unit in a timely manner to ensure the smooth brewing process of coffee. When the pour-over unit is installed, the liquid supply unit stops supplying liquid, realizing intelligent control of the liquid supply. This not only improves the automation level of the coffee machine, but also saves energy to a certain extent and avoids liquid waste.

[0006] In one embodiment, the pour-over assembly includes a faucet housing and a valve body assembly. The faucet housing is detachably mounted on the housing assembly and connected to the liquid supply assembly. The valve body assembly is mounted on the faucet housing and controls the flow of water through the faucet housing. The detachable faucet housing's key advantage lies in its flexible disassembly, allowing users to use it independently for pour-over coffee making, meeting the needs of traditional pour-over techniques. The connection between the faucet housing and the liquid supply assembly creates a stable liquid transmission channel, ensuring that the liquid output from the liquid supply assembly flows precisely and smoothly into the faucet housing, providing a stable liquid supply for the pour-over coffee process. This guarantees the stability of the liquid flow during brewing, allowing the pour-over operation to retain the flexibility of manual brewing while relying on the automated temperature control capabilities of the coffee machine. The valve body assembly, mounted on the faucet housing and controlling the water flow, allows users to precisely adjust the start and stop of the water flow and its speed according to the pour-over coffee process requirements, such as segmented water pouring and controlling extraction time, perfectly adapting to the professional pour-over requirements for water flow rhythm control. When liquid supply is not required, the water path is shut off via the valve assembly, effectively preventing liquid dripping and avoiding waste or countertop contamination, further enhancing the convenience and safety of pour-over operation. Furthermore, the cooperation between the faucet housing and the valve assembly forms an independent and complete water circuit control unit for the pour-over system. This unit works in conjunction with the liquid supply assembly, sensors, and other components to achieve a seamless transition from automatic liquid supply by the coffee machine to precise manual water control. This leverages the automation advantages of the equipment while preserving the craft experience of pour-over coffee, significantly improving the coffee machine's adaptability and professional brewing performance in various usage scenarios.

[0007] In one embodiment, the faucet housing includes a first pipeline assembly and a support ring. The support ring is disposed on and surrounds the first pipeline assembly. The sensor is disposed on the support ring. The housing assembly has a limiting hole, and the support ring is mounted on the limiting hole. The valve body assembly is disposed on the first pipeline assembly and is used to control the flow of water in the first pipeline assembly. The first pipeline assembly is connected to the liquid supply assembly via a pipeline. The support ring surrounds the first pipeline assembly and is mounted on the limiting hole of the housing assembly. This annular support structure provides uniform force support for the first pipeline assembly, preventing pipeline deformation due to liquid pressure or external impact, and ensuring the stability of liquid transmission. Simultaneously, the fit between the support ring and the limiting hole forms a precise installation positioning structure. Users can complete the installation of the faucet housing through a simple "set-up-embed" operation. Furthermore, the edge of the limiting hole prevents the support ring from moving vertically, ensuring the faucet housing is fixed in position after installation, thereby guaranteeing the sealing of the pipeline connection between the first pipeline assembly and the liquid supply assembly and reducing the risk of liquid leakage.

[0008] In one embodiment, the sensing element is a magnet, and the sensor is a reed switch.

[0009] In one embodiment, the faucet housing has a limiting groove located on the side of the faucet housing closest to the housing assembly, and the sensor is located at the limiting groove. The limiting groove on the faucet housing, located close to the housing assembly, provides precise installation and positioning space for the sensor. The shape and position of the limiting groove strictly define the installation position of the sensor, ensuring that it maintains an accurate relative position with the sensor on the housing assembly after installation. This avoids sensor malfunction due to installation misalignment and improves the reliability of the sensor in detecting the installation status of the hand-pouring assembly.

[0010] In one embodiment, the housing assembly has a limiting hole, which includes a support hole and a limiting notch. The limiting notch communicates with the support hole and is located on the side of the support hole closer to the housing assembly. The faucet housing includes a support ring that is adapted to both the support hole and the limiting notch. The sensor is located in the area where the limiting notch is located. The adaptation relationship between the limiting notch and the support ring forms an installation guidance mechanism: during installation, the support ring can slide into the support hole along the limiting notch, avoiding installation deviations caused by blind alignment and reducing operational difficulty; at the same time, the edge of the limiting notch provides circumferential restraint to the support ring, preventing it from rotating within the support hole and ensuring that the sensor is always directly facing the sensor, avoiding sensor malfunction due to positional misalignment.

[0011] In one embodiment, the housing assembly includes an outer shell assembly and a support assembly, the support assembly being disposed on the outer shell assembly, and the hand-held punch assembly being detachably disposed on the support assembly. The support assembly, disposed on the outer shell assembly, specifically provides a mounting support structure for the hand-held punch assembly. Compared to directly mounting the hand-held punch assembly on the outer shell assembly, the support assembly can be designed with precise mounting interfaces, such as limiting holes, based on the structural characteristics of the hand-held punch assembly. This ensures that the hand-held punch assembly is fixed in position and subjected to uniform force after installation, avoiding installation wobbling due to insufficient structural strength of the outer shell assembly, and ensuring the sensing accuracy of the sensing element and sensor.

[0012] In one embodiment, the bracket assembly has a mounting slot, and the sensor is mounted on the bracket assembly and located in the mounting slot. The mounting slot on the bracket assembly provides a precise installation and positioning space for the sensor. Its shape and size are adapted to the sensor, which can strictly limit the installation position of the sensor and ensure that the sensor and the sensing element on the hand-pump assembly maintain a precise relative positional relationship after installation. This avoids deviation of the sensing signal due to installation offset and improves the reliability of the hand-pump assembly installation status detection.

[0013] In one embodiment, the support assembly has a limiting hole, and the hand-held punch assembly is mounted on the support assembly and passes through the limiting hole. This mounting method, where the hand-held punch assembly passes through the limiting hole, allows the support assembly to provide uniform support through the hole wall, distributing the weight of the hand-held punch assembly and the pressure of the flowing liquid, avoiding structural deformation caused by single-point stress, and enhancing the stability after installation. Simultaneously, the edge of the limiting hole and the mounting location of the hand-held punch assembly form a stop structure, preventing the hand-held punch assembly from moving vertically.

[0014] In one embodiment, the liquid supply assembly includes a boiler assembly, a second pipeline assembly, and a control assembly. The boiler assembly and the second pipeline assembly are mounted on the housing assembly and are sequentially connected to the hand-drip assembly. The control assembly is electrically connected to both the boiler assembly and the sensor. The second pipeline assembly connects the boiler assembly and the hand-drip assembly, forming a closed liquid transmission channel. The second pipeline assembly mounted on the housing assembly can be fixed using the housing structure, with supports or clips used to prevent bending or loosening of the pipeline, ensuring the stability of the liquid flow rate. The sequential connection of the boiler assembly, the second pipeline assembly, and the hand-drip assembly constitutes a complete path from heating to water output, reducing the risk of leakage in intermediate stages, shortening the liquid transmission distance, reducing heat loss, and allowing the hand-drip assembly to obtain hot water with less temperature decay, ensuring the accuracy of the water temperature during the extraction process. The control assembly is electrically connected to both the boiler assembly and the sensor, realizing intelligent linkage control.

[0015] In one embodiment, the second piping assembly includes a mounting housing assembly and a pipe. The mounting housing assembly is disposed on the housing assembly, and the pipe is wound around the mounting housing assembly. One end of the pipe is connected to the boiler assembly, and the other end of the pipe is connected to the pour-over assembly. This structural design, consisting of the mounting housing assembly and the pipe, optimizes the liquid transport path and the utilization of internal space. The mounting housing assembly, disposed on the housing assembly, provides a stable mounting carrier for the pipe. The rigid support of the housing structure prevents deformation and bending of the pipe due to its own weight or liquid flow pressure, ensuring unobstructed internal channels, maintaining stable liquid flow, and preventing blockages from affecting the continuity of coffee brewing.

[0016] In one embodiment, the mounting housing assembly includes a mounting shell and a reset assembly. The mounting shell is disposed on the housing assembly, the reset assembly is disposed on the mounting shell, and the pipeline is wound around the reset assembly. The reset assembly allows the pipeline to retract and reset after stretching, ensuring ease of use and making it more convenient to operate.

[0017] The second aspect of this application discloses a coffee machine, comprising:

[0018] The aforementioned liquid supply system.

[0019] The coffee machine disclosed in this application has a detachable pour-over assembly mounted on the housing assembly, meeting the user's need for pour-over coffee after removal, while also facilitating deep cleaning and preventing coffee residue from affecting water quality and taste. A sensor is mounted on the pour-over assembly, and a matching sensor is mounted on the housing assembly. When the pour-over assembly is installed on the housing assembly, the sensor and the matching sensor sense each other, enabling the liquid supply assembly to automatically control the liquid supply based on the installation status of the pour-over assembly, achieving intelligent liquid supply control.

[0035] 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.

[0036] 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.

[0037] The following describes some embodiments of the liquid supply system and coffee machine of the present invention with reference to the accompanying drawings.

[0038] Example 1

[0039] like Figures 1 to 9 As shown, this embodiment discloses a liquid supply system for a coffee machine, comprising: a housing assembly 1; a pour-over assembly 2, which is detachably mounted on the housing assembly 1; a sensor 3; a sensor 4, one of which is mounted on the housing assembly 1, and the other of which is mounted on the pour-over assembly 2, wherein the sensor 4 and the sensor 3 are matched; and a liquid supply assembly 5, which is electrically connected to the sensor 4 and is connected to the pour-over assembly 2.

[0040] The liquid supply system disclosed in this application provides a stable installation foundation and structural support for the entire system, ensuring that each component maintains a relatively fixed position during the operation of the coffee machine and guaranteeing the stability of the system. The pour-over assembly 2 is detachably mounted on the housing assembly 1. This detachable design facilitates user operation and meets the needs of different usage scenarios, improving the convenience and flexibility of the coffee machine. One of the sensors, 3 and 4, is mounted on the pour-over assembly 2, while the other is mounted on the housing assembly 1, with the sensor 4 matching the sensor 3. Through the cooperation of the sensor 3 and sensor 4, accurate detection of the installation status of the pour-over assembly 2 can be achieved. When the pour-over assembly 2 is correctly installed on the housing assembly 1, the sensor 4 detects the sensor 3, causing the liquid supply assembly 5 to stop working. If the pour-over assembly 2 is not properly installed or the sensor 4 cannot detect the sensor 3, the liquid supply assembly 5 starts working, facilitating manual coffee brewing and meeting more usage scenarios. The liquid supply assembly 5 is electrically connected to the sensor 4 and also to the pour-over assembly 2, enabling the liquid supply assembly 5 to control the liquid supply based on the detection signal from the sensor 4. When the pour-over assembly 2 is removed, it can be preheated, and the liquid supply assembly 5 supplies liquid to the pour-over assembly 2 in a timely manner to ensure the smooth progress of the coffee brewing process. When the pour-over assembly 2 is installed, the liquid supply assembly 5 stops supplying liquid, realizing intelligent control of the liquid supply. This not only improves the automation level of the coffee machine but also saves energy to a certain extent and avoids liquid waste.

[0041] like Figure 4 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the pour-over assembly 2 includes a faucet housing 21 and a valve body assembly 22. The faucet housing 21 is detachably mounted on the housing assembly 1 and is connected to the liquid supply assembly 5. The valve body assembly 22 is mounted on the faucet housing 21 and is used to control the flow of water through the faucet housing 21. The detachable mounting of the faucet housing 21 on the housing assembly 1 has the core advantage of enabling flexible disassembly of the pour-over assembly 2. Users can remove it and use it independently for pour-over coffee operation, meeting the needs of traditional pour-over processes. The connection between the faucet housing 21 and the liquid supply assembly 5 establishes a stable liquid transmission channel, allowing the liquid output from the liquid supply assembly 5 to flow accurately and smoothly into the faucet housing 21, providing a stable liquid supply for the pour-over coffee process, ensuring the stability of the liquid flow during brewing, and allowing the pour-over operation to rely on the automatic temperature control capabilities of the coffee machine while maintaining the flexibility of manual brewing. The valve assembly 22 is mounted on the faucet housing 21 and controls the water flow. This design allows users to precisely adjust the water flow and speed according to the process requirements of pour-over coffee, such as segmented water injection and control of extraction time, perfectly matching the professional pour-over coffee's requirements for water flow rhythm control. When liquid supply is not needed, the water flow can be closed by the valve assembly 22, effectively preventing liquid leakage, avoiding waste or countertop contamination, and further enhancing the convenience and safety of pour-over operation. In addition, the cooperation between the faucet housing 21 and the valve assembly 22 makes the pour-over component 2 an independent and complete water circuit control unit. This unit works in conjunction with components such as the liquid supply component 5 and the sensor 4 to realize the functional connection from automatic liquid supply by the coffee machine to precise manual water control. It not only leverages the automation advantages of the equipment but also retains the process experience of pour-over coffee, greatly improving the adaptability and professional brewing performance of the coffee machine in different usage scenarios.

[0042] like Figure 4 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the faucet housing 21 includes a first pipeline assembly 211 and a support ring 212. The support ring 212 is disposed on and surrounds the first pipeline assembly 211. The sensor 3 is disposed on the support ring 212. The housing assembly 1 has a limiting hole 101. The support ring 212 is mounted at the limiting hole 101. The valve body assembly 22 is disposed on the first pipeline assembly 211. The valve body assembly 22 is used to control the flow of water in the first pipeline assembly 211. The first pipeline assembly 211 is connected to the liquid supply assembly 5 through a pipeline. The support ring 212 surrounds the first pipeline assembly 211 and is mounted at the limiting hole 101 of the housing assembly 1. This annular support structure provides uniform force support for the first pipeline assembly 211, avoiding pipeline deformation due to liquid pressure or external collisions, and ensuring the stability of liquid transmission. Meanwhile, the fitting of the support ring 212 and the limiting hole 101 forms a precise installation and positioning structure. Users can complete the installation of the faucet housing 21 through a simple "set-up-embed" operation. The edge of the limiting hole 101 can prevent the support ring 212 from moving in the vertical direction, ensuring that the faucet housing 21 is fixed in position after installation. This ensures the sealing of the pipeline connection between the first pipeline assembly 211 and the liquid supply assembly 5, reducing the risk of liquid leakage.

[0043] In addition to the features of the above embodiments, this embodiment further specifies that: the sensing element 3 is a magnet and the sensor 4 is a reed switch.

The limiting groove 2101 on the faucet housing 21 is located on the side near the housing assembly 1, and the sensor 3 is disposed here, which firstly provides a precise installation positioning space for the sensor 3. The shape and position of the limiting groove 2101 can strictly limit the installation position of the sensor 3, ensuring that it maintains an accurate relative position with the sensor 4 on the housing assembly 1 after installation, avoiding sensor failure due to installation misalignment, and improving the reliability of the sensor 4 in detecting the installation status of the hand-pouring assembly 2.

[0045] like Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 is provided with a limiting hole 101, the limiting hole 101 includes a support hole 1011 and a limiting notch 1012, the limiting notch 1012 communicates with the support hole 1011, the limiting notch 1012 is located on the side of the support hole 1011 close to the housing assembly 1, the faucet housing 21 includes a support ring 212, the support ring 212 is adapted to the support hole 1011 and the limiting notch 1012, and the sensing element 3 is located in the area where the limiting notch 1012 is located. The fitting relationship between the limiting notch 1012 and the support ring 212 forms an installation guidance mechanism: during installation, the support ring 212 can slide into the support hole 1011 along the limiting notch 1012, avoiding installation deviations caused by blind docking and reducing the difficulty of operation; at the same time, the edge of the limiting notch 1012 forms a circumferential limit on the support ring 212, preventing it from rotating in the support hole 1011, ensuring that the sensing element 3 is always facing the sensor 4, and avoiding sensing failure due to positional deviation.

[0046] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 includes an outer shell assembly 11 and a bracket assembly 12, the bracket assembly 12 is disposed on the outer shell assembly 11, and the hand-pump assembly 2 is detachably disposed on the bracket assembly 12. The bracket assembly 12 is disposed on the outer shell assembly 11 and specifically provides a mounting support structure for the hand-pump assembly 2. Compared to directly mounting the hand-pump assembly 2 on the outer shell assembly 11, the bracket assembly 12 can be designed with precise mounting interfaces such as limiting holes 101 according to the structural characteristics of the hand-pump assembly 2, ensuring that the hand-pump assembly 2 is fixed in position and evenly stressed after installation, avoiding installation shaking caused by insufficient structural strength of the outer shell assembly 11, and ensuring the sensing accuracy of the sensing element 3 and the sensor 4.

[0047] like Figure 3 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the bracket assembly 12 is provided with a mounting groove 1201, and the sensor 4 is disposed on the bracket assembly 12 and located at the mounting groove 1201. The mounting groove 1201 on the bracket assembly 12 provides a precise installation and positioning space for the sensor 4. Its shape and size are adapted to the sensor 4, which can strictly limit the installation position of the sensor 4, ensure that the sensor 4 and the sensing element 3 on the hand-pump assembly 2 maintain a precise relative positional relationship after installation, avoid the deviation of the sensing signal due to installation offset, and improve the reliability of the installation status detection of the hand-pump assembly 2.

The way the hand-pump assembly 2 passes through the limiting hole 101 allows the support assembly 12 to provide uniform support through the hole wall of the limiting hole 101, distributing the weight of the hand-pump assembly 2 and the pressure during liquid flow, avoiding structural deformation caused by single-point stress, and enhancing the stability after installation. At the same time, the edge of the limiting hole 101 and the mounting part of the hand-pump assembly 2 form a stop structure, which can prevent the hand-pump assembly 2 from moving vertically.

The control component is electrically connected to the boiler component 51 and the sensor 4, respectively. The second pipeline component 52 connects the boiler component 51 and the hand-pour component 2, forming a closed liquid transmission channel. The second pipeline component 52 mounted on the housing component 1 can be fixed by means of the housing structure, and the pipe bending and loosening are prevented by means of brackets or buckles, ensuring the stability of the liquid flow rate. The sequential connection of the boiler component 51, the second pipeline component 52, and the hand-pour component 2 constitutes a complete path from heating to water output, reducing the risk of leakage in intermediate links, shortening the liquid transmission distance, reducing heat loss, and enabling the hand-pour component 2 to obtain hot water with less temperature decay, ensuring the accuracy of the water temperature in the extraction process. The control component is electrically connected to the boiler component 51 and the sensor 4, realizing intelligent linkage control.

The mounting housing assembly 521, disposed on the housing assembly 1, provides a stable mounting carrier for the pipeline 522. Through the rigid support of the housing structure, the pipeline 522 is prevented from deforming or bending due to its own weight or liquid flow pressure, ensuring the unobstructed flow of the internal passage of the pipeline 522, maintaining the stability of the liquid flow, and preventing the continuity of coffee brewing from being affected by pipeline blockage.

[0051] like Figure 5 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting housing assembly 521 includes a mounting housing 5211 and a reset assembly 5212.
