Description

Technical Field

[0001] This application relates to the field of coffee brewing technology, and more particularly to a brewing device and coffee brewing equipment. Background Technology

[0002] There are many types of coffee machines available, but drip coffee machines are popular among consumers due to their simple structure, the need for atmospheric pressure brewing, and their easy and reliable operation, making them ideal for home or office use. However, current drip coffee machines on the market have structural limitations that prevent the complete removal of contaminated parts of the brewing device for cleaning and maintenance, posing significant hygiene problems. In particular, the issue of coffee grounds in the brewing mechanism is problematic; continuous use leads to significant coffee grounds buildup, making cleaning difficult and potentially causing food safety issues. For example, Chinese patent CN208610608U discloses a drip coffee machine comprising a casing, a shower head, a brewing basket, a water tank, a coffee pot, a first rotating shaft, a second rotating shaft, and a top cover. The top cover is hinged to the casing via the first rotating shaft, and one end of the shower head is hinged to the casing via the second rotating shaft. The lower part of the top cover has a cavity with a receiving groove, and an elastic element with a movable groove is installed within the receiving groove. It is evident that the brewing basket of this drip coffee machine cannot be easily disassembled for cleaning, making deep cleaning impossible and resulting in a poor user experience. Summary of the Invention

[0003] In view of the above-mentioned technical problems existing in the prior art, this application provides a brewing device and a coffee brewing equipment, which can solve the technical problem that the brewing chamber components cannot be disassembled and cleaned.

[0004] This application provides a brewing device, including:

[0005] A brewing device includes a mounting cavity and a first drive assembly disposed at the bottom of the mounting cavity, wherein a first connector is provided in the mounting cavity and is drively connected to the first drive assembly;

[0006] A brewing chamber assembly is detachably installed within the mounting cavity. The brewing chamber assembly includes a chamber body assembly and a first plunger assembly. The first plunger assembly is slidably disposed within the brewing chamber of the chamber body assembly. The first plunger assembly includes a second connector that mates with the first connector. The first and second connectors cooperate to form a liquid outlet channel communicating with the brewing chamber. A first drive assembly is used to drive the first plunger assembly and the first connector to move synchronously up and down within the chamber body assembly. This structure enables the brewing chamber assembly to be detachable, facilitating user rinsing or soaking the disassembled assembly with water.

[0007] In some embodiments, the brewing chamber assembly further includes a foolproof component disposed at the bottom of the chamber assembly. The foolproof component has a locked state where it is inserted into the inner wall of the mounting cavity, and an unlocked state where it is away from the inner wall of the mounting cavity. When the first plunger assembly moves to the bottom of the chamber assembly, it acts on the foolproof component, causing the foolproof component to switch from the locked state to the unlocked state, so that the brewing chamber assembly can be detached from the brewer. This structure ensures that the first plunger assembly can be stably installed on the brewer when it has not moved to the bottom of the chamber assembly, and prevents the brewing chamber assembly from being incorrectly installed during user cleaning and maintenance, thus avoiding any impact on the function of the coffee brewing equipment.

[0008] In some embodiments, the brewing device further includes a transmission assembly, which includes a lead screw structure pulsatingly connected to the first drive assembly. The first drive assembly drives the first plunger assembly and the first connector to move synchronously up and down within the cavity assembly via the lead screw structure. The lead screw structure has a first end face located within the mounting cavity, and both the first connector and the brewing cavity assembly are disposed on the first end face. The first end face of the lead screw structure extends into the brewing cavity from the bottom of the cavity assembly to drive the first plunger assembly and the first connector. This allows the lead screw structure to stably drive a plunger assembly and the first connector to move synchronously up and down within the cavity assembly.

[0009] In some embodiments, the cavity assembly includes a cavity body on which the brewing cavity is formed. Resilient mounting components are respectively provided on opposite sides of the cavity body. Each resilient mounting component includes a snap-fit ​​and an elastic element. The brewer has a slot, and the elastic element applies a force to the snap-fit ​​to engage with the slot, thereby securing the cavity assembly to the brewer. This structure allows the user to easily install or remove the cavity assembly from the brewer by applying force to the resilient mounting components, providing convenient operation and structural stability.

[0010] In some embodiments, the first plunger assembly includes a filter screen and a lower plunger disposed below the filter screen. The second connector is mounted on the lower part of the lower plunger. Cavities are provided on opposite sides of the lower plunger, and spring-loaded assemblies are disposed within these cavities. The bottom of the cavity assembly has a locking portion that interacts with the spring-loaded assemblies to position the first plunger assembly as it moves to the bottom of the cavity assembly. This spring-loaded structure allows the first plunger assembly to remain in that position after moving to the bottom of the cavity assembly, preventing the first plunger assembly from floating upwards due to force.

[0011] In some embodiments, at least one detection device is provided within the mounting cavity. This detection device is used to detect the assembly / disassembly status of the brewing chamber assembly and the brewer. The first driving assembly operates when the brewing chamber assembly is mounted on the brewer. By accurately detecting the assembly / disassembly status of the brewing chamber assembly, the coffee brewing equipment using the brewing device can perform functions such as receiving coffee grounds, adding water, drip filtering, and removing sediment after the brewing chamber assembly is properly installed.

[0012] In some embodiments, the foolproof assembly includes a foolproof spring and foolproof pins acting on both ends of the foolproof spring. The mounting cavity has slots on the inner wall corresponding to the foolproof pins. The foolproof spring applies a force to the foolproof pins to insert them into the slots. The interaction between the foolproof pins and the slots is stable, and the structure is simple and compact.

[0013] In some embodiments, the anti-misalignment pin is provided with a protrusion, and the first plunger assembly has a retractable groove. The retractable groove acts on the protrusion when the plunger moves to the bottom of the cavity assembly, causing the protrusion to retract relative to the plunger, thereby driving the anti-misalignment pin to move closer together and disengage from the slot. The protrusion and retractable groove provide a stable force on the anti-misalignment pin, enabling it to disengage from the slot. The structure is simple, and the interaction is stable.

[0014] In some embodiments, the second connector is provided with a guide post and a guide groove, and the first connector is provided with a groove adapted to the guide post and a limiting cavity adapted to the guide groove. The guide post and guide groove enable precise docking of the first and second connectors, ensuring the stability and accuracy of the docking and preventing leakage.

[0015] This application also provides a coffee brewing apparatus, including the brewing device as described above. The above structure allows for the detachment of the brewing chamber assembly, facilitating the user to rinse or soak the disassembled brewing chamber assembly with water.

[0016] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: This application achieves the detachability of the brewing chamber unit by detachably installing the brewing chamber assembly in the installation cavity. This allows users to easily rinse or soak the disassembled brewing chamber unit with water and then reinstall the cleaned brewing chamber unit on the brewer for the next brewing of coffee. Furthermore, the brewing chamber assembly can be further disassembled into a chamber assembly and a first plunger assembly, facilitating further deep cleaning and maintenance, thus increasing user convenience. A liquid outlet channel is formed between the brewer and the brewing chamber assembly through the cooperation of the first connector and the second connector for discharging the brewed coffee liquid. The above structure ensures the sealing of the liquid outlet, allowing the coffee liquid to be smoothly discharged through the liquid outlet channel. Attached Figure Description

[0036] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] This application provides a brewing device. For example... Figures 1 to 9As shown, the brewing device includes a brewer 1 and a brewing chamber assembly 2. The brewer 1 includes a mounting cavity 101 and a first drive assembly 102 disposed at the bottom of the mounting cavity 101. A first connector 103, which is drively connected to the first drive assembly 102, is disposed in the mounting cavity 101. The brewing chamber assembly 2 is detachably installed in the mounting cavity 101. The brewing chamber assembly 2 includes a chamber body assembly 201 and a first plunger assembly 203. The first plunger assembly 203 is slidably disposed in the brewing chamber 202 of the chamber body assembly 201. The first plunger assembly 203 includes a second connector 204 that mates with the first connector 103. The first connector 103 and the second connector 204 cooperate to form a liquid outlet channel communicating with the brewing chamber 202. The first drive assembly 102 is used to drive the first plunger assembly 203 and the first connector 103 to move up and down synchronously within the chamber body assembly 201.

[0038] The brewing chamber assembly 2 has an installed state within the mounting cavity 101 and a disassembled state detached from the mounting cavity 101. When the brewing chamber assembly 2 is in the installed state, the coffee brewing equipment using the brewing device can perform functions such as receiving coffee grounds, adding water, drip filtering, and removing grounds. When the brewing chamber assembly 2 is in the disassembled state, the coffee brewing equipment using the brewing device cannot perform these functions, ensuring the safety and stability of equipment operation and preventing malfunctions.

[0039] After the brewer 1 and the brewing chamber assembly 2 are detached, they can be understood as two independent components, thus enabling a comprehensive cleaning of the brewing chamber assembly 2. Furthermore, the disassembled brewing chamber assembly 2 only includes the chamber body assembly 201 and the first plunger assembly 203, without needing to disassemble components such as the first drive assembly 102 and the first connector 103, simplifying the disassembly of the components. The disassembled brewing chamber assembly 2 can be cleaned as a whole. Of course, the chamber body assembly 201 and the first plunger assembly 203 can be detachably connected, allowing the brewing chamber assembly 2 to be further disassembled into these two components, enabling separate cleaning of the chamber body assembly 201 and the first plunger assembly 203, further optimizing the cleaning effect. Specifically, the chamber body assembly 201 can be connected at both ends along the direction of movement of the first plunger assembly 203, allowing the first plunger assembly 203 to pass through the chamber body assembly 201 along its direction of movement, achieving the purpose of detaching the first plunger assembly 203 from the chamber body assembly 201.

[0040] Optionally, the above-mentioned brewing device may include a second plunger assembly 8 and a scraper 7. The second plunger assembly 8 is disposed above the brewing chamber assembly 2, and the second plunger assembly 8 is capable of moving in a lateral direction perpendicular to the lifting direction of the first plunger assembly 203. Figures 10 to 12 as well as Figure 14As shown in the figure, the second plunger assembly 8 is in the first position, and in the first position, the second plunger assembly 8 is away from the upper opening of the brewing chamber 202 of the chamber assembly 201. Figure 15 As shown in the figure, the second plunger assembly 8 is in the second position. The second plunger assembly 8 in the first position can be moved to the second position by lateral movement.

[0041] Furthermore, the second plunger assembly 8 can also move towards the upper opening of the brewing chamber 202 in the second position to seal the upper opening of the brewing chamber 202. For example, as Figure 13 As shown in the figure, the second plunger assembly 8 is in the third position. The second plunger assembly 8 in the second position can move downward to cover the upper opening of the brewing chamber 202, so that the second plunger assembly 8 can move from the second position to the third position.

[0042] The aforementioned scraper 7 can be disposed on one end of the second plunger assembly 8 near the upper opening of the brewing chamber 202. After coffee preparation is completed, the second plunger assembly 8 can move from the first position to the second position to drive the scraper 7 to move in the direction of the coffee grounds on the first plunger assembly 203, so as to push the coffee grounds out of the brewer 1.

[0043] Optionally, the first connector 103 and the second connector 204 can be connected by a soft rubber mat or a sealing ring. This application does not make a specific limitation on this, as long as the first connector 103 and the second connector 204 can be sealed together after the brewing chamber assembly 2 is installed on the brewer 1.

[0044] Optionally, a cavity for containing coffee powder can be formed between the upper surface of the first plunger assembly 203 and the brewing chamber 202. Hot water enters the cavity to brew the coffee powder. The brewed coffee liquid can be discharged outward through the liquid outlet channel formed by the cooperation of the first connector 103 and the second connector 204, while the brewed coffee grounds will remain on the first plunger assembly 203.

[0045] Optionally, one end of the first drive assembly 102 connected to the first connector 103 can move up and down synchronously with the first connector 103 and the first plunger assembly 203 within the cavity assembly 201. That is, this end of the first drive assembly 102 can extend into or out of the cavity assembly 201, making the structure more compact and reasonable.

[0046] Optionally, the brewer 1 may also include a frame, on which the first drive assembly 102 and the second plunger assembly 8 are both mounted. The frame can limit the movement of the second plunger assembly 8 and can also stably mount the first drive assembly 102. After the brewing chamber assembly 2 is disengaged from the brewer 1, the first drive assembly 102 and the first connector 103 can remain stably mounted on the frame.

[0047] Optionally, the stroke of the first plunger assembly 203 within the brewing chamber 202 may have an upper limit position and a lower limit position, for example, as shown in the example. Figure 2 , Figure 10 , Figure 12 , Figure 13 as well as Figure 16 As shown in the figure, the first plunger assembly 203 is in the lower limit position; as Figure 1 , Figure 11 , Figure 14 as well as Figure 15 As shown in the figure, the first plunger assembly 203 is in the upper limit position.

[0048] Optionally, the brewing chamber assembly 2 at the lower limit position is in a detachable state, and the brewing chamber assembly 2 at the upper limit position is in a non-detachable state. That is, the brewing chamber assembly 2 can only be detached when it moves to the bottom of the brewing chamber 202. When the brewing chamber assembly 2 is not at the bottom of the brewing chamber 202, the brewing chamber assembly cannot be detached.

[0049] The coffee brewing equipment using the above-mentioned brewing device can have an initial mode, a powder receiving mode, a brewing mode, a grounds pushing mode, a grounds scraping mode, and a maintenance mode. The various modes of the coffee brewing equipment using the above-mentioned brewing device will be described in detail below, and will not be repeated here. Among them, Figure 1 and Figure 11 The brewing device shown is in the initial mode; Figure 12 The brewing device shown is in powder receiving mode; Figure 13 The brewing device shown is in brewing mode; Figure 14 The brewing device shown is in the grounds pushing mode. In the grounds pushing mode, the first plunger assembly 203 pushes the coffee grounds formed after brewing upwards to the position corresponding to the scraper 7. Figure 15 The brewing device shown is in the scraping mode. In the scraping mode, the coffee grounds on the first plunger assembly 203 are pushed to the outside of the brewer 1 by the scraper blade 7. Figure 2 , Figure 10 as well as Figure 16 The brewing device shown is in maintenance mode.

[0050] In maintenance mode, the first plunger assembly 203 of the brewing chamber assembly 2 can be moved to the lower limit position. Then, the user can manually detach the brewing chamber assembly 2 from the brewer 1. At this time, the first connector 103 and the second connector 204 can be separated. Then, the brewing chamber assembly 2 can be removed from the brewer 1 for rinsing. Furthermore, the brewing chamber assembly 2 can be disassembled into two parts: the chamber assembly 201 and the first plunger assembly 203, for cleaning separately to achieve a better cleaning effect.

[0051] After maintenance and cleaning, the brewing chamber assembly 2 can be installed in the installation cavity 101 of the brewer 1, and the first connector 103 and the second connector 204 can be connected to form a liquid outlet channel. This allows the coffee brewing equipment using the above-mentioned brewing device to restore its brewing-related functions, such as receiving powder, pouring water, drip filtering, and discharging residue, after the brewing chamber assembly 2 has been installed in place.

[0052] Optionally, a guide structure may be provided inside the mounting cavity 101, and a guide groove 213 adapted to the guide structure may be provided on the outer wall of the cavity assembly 201 to guide the cavity assembly 201 to be installed in a designated position inside the mounting cavity 101 to achieve the purpose of precise installation.

[0053] This application achieves detachability of the brewing chamber assembly 2 by detachably installing it within the mounting cavity 101. This allows users to easily rinse or soak the disassembled assembly with water before reinstalling it back onto the brewer 1 for the next brewing. Furthermore, the brewing chamber assembly 2 can be further disassembled into a cavity assembly 201 and a first plunger assembly 203, facilitating deeper cleaning and maintenance and increasing user convenience. A liquid outlet channel is formed between the brewer 1 and the brewing chamber assembly 2 through the cooperation of the first connector 103 and the second connector 204, for discharging the brewed coffee liquid. This structure ensures a tight seal at the outlet, allowing the coffee liquid to be smoothly discharged through the outlet channel.

[0054] In some embodiments, such as Figure 3 , Figure 5 and Figure 7 As shown, the brewing chamber assembly 2 also includes a foolproof component 3 located at the bottom of the chamber assembly 201. The foolproof component 3 has a locked state where it is inserted into the inner wall of the mounting cavity 101, and an unlocked state where it is away from the inner wall of the mounting cavity 101. When the first plunger assembly 203 moves to the bottom of the chamber assembly 201, it acts on the foolproof component 3, causing the foolproof component 3 to switch from the locked state to the unlocked state, so that the brewing chamber assembly 2 can be detached from the brewer 1. Figure 3 The foolproof component 3 shown is in the unlocked state.

[0055] Thus, by setting the aforementioned foolproof component 3, the first plunger assembly 203 can only be detached from the brewer 1 when it moves to the bottom of the cavity assembly 201. This ensures that the first plunger assembly 203 can be stably installed on the brewer 1 when it has not moved to the bottom of the cavity assembly 201. Furthermore, it prevents the brewing cavity assembly 2 from being incorrectly installed during user cleaning and maintenance, thus avoiding any impact on the function of the coffee brewing equipment.

[0056] like Figure 2 , Figure 10 , Figure 12 , Figure 13 as well as Figure 16 As shown in the figure, the first plunger assembly 203 is in the lower limit position, and the foolproof assembly 3 is in the unlocked state; as Figure 1 , Figure 11 , Figure 14 as well as Figure 15 As shown in the figure, the first plunger assembly 203 is in the upper limit position, and the foolproof component 3 is in the locked state. The brewing chamber assembly 2 is in a detachable state in the lower limit position and in a non-detachable state in the upper limit position. The foolproof component 3 ensures that the brewing chamber assembly 2 can only be removed when it is in a specified position, which facilitates cleaning of the brewing chamber assembly 2 and increases the installation stability of the brewing chamber assembly 2.

[0057] When the first plunger assembly 203 moves above the bottom of the cavity assembly 201, the foolproof component 3 can be understood as remaining in a locked state to increase the installation stability of the first plunger assembly 203.

[0058] Optionally, the brewing chamber 202 of the cavity assembly 201 can be understood as a through chamber, which runs through both the upper and lower ends of the cavity assembly 201. The foolproof component 3 has an action part corresponding to the through chamber. When the first plunger assembly 203 moves to the bottom of the cavity assembly 201, it can act on the action part to switch the foolproof component 3 from the locked state to the unlocked state.

[0059] In some embodiments, such as Figure 3 as well as Figures 9 to 16 As shown, the brewing device 1 also includes a transmission assembly 4, which includes a lead screw structure 401 that is connected to the first drive assembly 102. The first drive assembly 102 drives the first plunger assembly 203 and the first connector 103 to move up and down synchronously within the cavity assembly 201 via the lead screw structure 401. The lead screw structure 401 has a first end face 402 located within the mounting cavity 101. The first connector 103 and the brewing cavity assembly 2 are both located on the first end face 402. The first end face 402 of the lead screw structure 401 extends into the brewing cavity 202 from the bottom of the brewing cavity 202 to drive the first plunger assembly 203 and the first connector 103 to move.

[0060] In this way, by both the first plunger assembly 203 and the first connector 103 are mounted on the first end face 402 of the lead screw structure 401, the lead screw structure 401 can stably drive the first plunger assembly 203 and the first connector 103 to move up and down synchronously within the cavity assembly 201. Furthermore, one end of the lead screw structure 401 can simultaneously penetrate into the brewing cavity 202 along with the first plunger assembly 203, resulting in a more compact and rational structural layout, and significantly reducing the size of the detachable brewing cavity assembly 2.

[0061] Optionally, such as Figure 9 As shown, the transmission assembly 4 may also include a gear assembly 403, and the first drive assembly 102 can drive the lead screw structure 401 to perform stable lifting and lowering movements through the gear assembly 403.

[0062] Specifically, the gear assembly 403 may include a driving gear and a driven gear that are connected by a transmission. The driving gear is connected to the output shaft of the first drive assembly 102, and the driven gear rotates under the drive of the driving gear. The driven gear may be configured as a lead screw gear, which is rotatably mounted outside the lead screw structure 401 so that the rotation of the lead screw gear drives the lead screw structure 401 to perform lifting and lowering movements.

[0063] Optionally, the first connector 103 may be installed on the first end face 402 of the lead screw structure 401 in a detachable connection manner.

[0064] In some embodiments, such as Figures 1 to 5 As shown, the cavity assembly 201 includes a cavity body 205 with a brewing cavity 202 formed thereon. Elastic mounting components 5 are respectively provided on opposite sides of the cavity body 205. The elastic mounting components 5 include a buckle 501 and an elastic element 502. The brewer 1 is provided with a slot 104. The elastic element 502 is used to apply a force to the buckle 501 to make it engage with the slot 104, so as to limit the cavity assembly 201 on the brewer 1.

[0065] The above structure allows the user to install or remove the cavity assembly 201 from the brewer 1 by applying force to the elastic mounting component 5, which is convenient to operate and structurally stable.

[0066] Optionally, the latch 501 can be relatively close to or away from the cavity body 205. The elastic element 502 is used to apply a force to the latch 501, causing the latch 501 to move away from the cavity body 205, so that the latch 501 can be stably engaged with the slot 104. The user can apply force to the latch 501 to move the latch 501 closer to the cavity body 205, so that the latch 501 can move away from the slot 104, thereby unlocking the slot 104 and the latch 501, and allowing the cavity assembly 201 to be moved away from the brewer 1.

[0067] The flexible mounting components 5 are located on opposite sides of the cavity body 205, allowing users to simultaneously press and pinch the left and right sides of the cavity body 205, increasing user convenience.

[0068] In some embodiments, such as Figures 1 to 6 as well as Figure 16As shown, the first plunger assembly 203 includes a filter screen 206 and a lower plunger 207 located below the filter screen 206. The second connector 204 is installed on the lower part of the lower plunger 207. The lower plunger 207 has cavities 208 on opposite sides. A spring-loaded assembly 209 is provided in the cavity 208. The bottom of the cavity assembly 201 has a snap-fit ​​part 210 that interacts with the spring-loaded assembly 209 to position the first plunger assembly 203 that moves to the bottom of the cavity assembly 201.

[0069] In this way, the spring-loaded structure allows the first plunger assembly 203 to move to the bottom of the cavity assembly 201 and remain in that position, avoiding the problem of the first plunger assembly 203 floating upward due to the force. Furthermore, when the brewing cavity assembly 2 is installed on the brewer 1, the force between the spring-loaded assembly 209 and the snap-fit ​​part 210 at the bottom of the cavity assembly ensures the alignment of the second connector 204 of the brewing cavity assembly 2 and the first connector 103 in the mounting cavity 101, thus ensuring the effectiveness of the liquid outlet channel.

[0070] Optionally, such as Figure 6 As shown, a sealing ring 214 can be fitted onto the outer wall of the lower plunger 207 to ensure a sealed connection between the lower plunger 207 and the brewing chamber 202. When the first plunger assembly 203 moves to the bottom of the chamber assembly 201, the sealing ring 214 will generate a force that causes the first plunger assembly 203 to float. Thus, by providing the spring-loaded assembly 209 and the snap-fit ​​part 210, the first plunger assembly 203 can be stably maintained at the bottom of the chamber assembly 201.

[0071] Optionally, the spring-loaded assembly 209 may include a spring and an extension that can move in the direction of the brewing chamber 202 under the action of the spring, the extension being able to engage with the locking part 210.

[0072] Optionally, the second connector 204 can be detachably installed at the bottom of the lower plunger 207.

[0073] In some embodiments, such as Figure 10 As shown, at least one detection device 6 is provided in the mounting cavity 101. The detection device 6 is used to detect the disassembly and assembly status of the brewing chamber assembly 2 and the brewer 1. The first drive assembly 102 is used to operate when the brewing chamber assembly 2 is installed on the brewer 1. The above-mentioned detector can accurately detect the disassembly and assembly status of the brewing chamber assembly 2, so that after the brewing chamber assembly 2 is installed in place, the coffee brewing equipment using the brewing device can have functions such as receiving powder, injecting water, drip filtering, and discharging residue.

[0074] Optionally, the detection device 6 can be configured as a Hall effect sensor, and a magnetic element 601 can be provided on the outer wall of the cavity assembly 201. When the brewing cavity assembly 2 is installed in the installation cavity 101, the Hall effect sensor will sense the magnetic element 601 on the outer wall of the cavity assembly 201 to generate a command that the brewing cavity assembly 2 is installed in place.

[0075] In some embodiments, such as Figure 3 , Figure 5 and Figure 7 As shown, the foolproof component 3 includes a foolproof spring 301 and foolproof pins 302 that act on both ends of the foolproof spring 301. A slot 105 is provided on the inner wall of the mounting cavity 101 corresponding to the foolproof pin 302. The foolproof spring 301 applies a force to the foolproof pin 302 to insert it into the slot 105. The interaction between the foolproof pin 302 and the slot 105 is stable, and the structure is simple and compact.

[0076] Optionally, the aforementioned anti-mistake component 3 may further include a cover plate 304 installed at the bottom of the cavity assembly 201, with an anti-mistake spring 301 and an anti-mistake pin 302 disposed on the cover plate 304.

[0077] In some embodiments, such as Figure 5 and Figure 7 As shown, the anti-misalignment pin 302 is provided with a protrusion 303, and the first plunger assembly 203 has a retracting groove 211. The retracting groove 211 acts on the protrusion 303 when it moves to the bottom of the cavity assembly 201, causing the protrusion 303 to retract relatively, thereby driving the anti-misalignment pin 302 to move closer together and disengage from the slot 105. The protrusion 303 and the retracting groove 211 can stably act on the anti-misalignment pin 302, allowing the anti-misalignment pin 302 to disengage from the slot 105. The above structure is simple and the working relationship is stable.

[0078] Optionally, the aforementioned gathering groove 211 can be constructed as a figure-eight groove, which has two through grooves. The two channels have one end close to each other and one end far apart. When the first plunger assembly 203 moves to the bottom of the cavity assembly 201, the protrusion 303 will be inserted into the through groove from the end far apart from the figure-eight groove, and then move towards the end close to the figure-eight groove, thereby driving the two anti-fool pins 302 to move closer to each other in the direction of disengaging from the slot 105.

[0079] In some embodiments, such as Figure 3 and Figure 6As shown, the second connector 204 is provided with a guide post 212 and a guide groove 213, and the first connector 103 is provided with a groove 106 adapted to the guide post 212 and a limiting cavity 107 adapted to the guide groove 213. The guide post 212 and guide groove 213 enable precise docking of the first connector 103 and the second connector 204, ensuring the stability and accuracy of the docking and preventing leakage.

[0080] The following provides a detailed description of the various modes of coffee brewing equipment using the aforementioned brewing device. For example... Figure 1 and Figure 11 As shown, in the initial mode, the second plunger assembly 8 is at the leftmost end, and the first plunger assembly 203 is at the upper end of the cavity assembly 201, that is, the second plunger assembly 8 is in the first position, and the first plunger assembly 203 is in the upper limit position. The control panel of the coffee brewing equipment can receive the user's preparation instructions to brew coffee. After the initial mode ends, it enters the powder receiving mode. At this time, as shown... Figure 12 As shown, the first plunger assembly 203 will move to the lower limit position, and the coffee brewing equipment can start its grinder to grind the coffee powder and discharge the ground coffee powder into the brewing chamber 202 of the chamber assembly 201, that is, above the first plunger assembly 203.

[0081] like Figure 13 As shown, the coffee brewing mode then transitions from the powder receiving mode to the brewing mode. The second plunger assembly 8 moves sequentially from the first position to the second and third positions to seal the upper opening of the brewing chamber 202. The water pump of the coffee brewing equipment then pumps water into the boiler. The boiler discharges hot water, which is then sprayed into the brewing chamber 202 via the second plunger assembly 8. Once the water reaches the set capacity, the water pump stops. The air pump of the coffee brewing equipment then blows air into the brewing chamber 202 via the second plunger assembly 8. Because the upper part of the brewing chamber 202 is sealed at this time, the continuous influx of hot water and a large amount of steam creates a certain pressure (approximately 0.6 bar), which accelerates the drip filtration process, thereby shortening the brewing time for drip coffee.

[0082] like Figure 14 and Figure 15 As shown, after the brewing mode ends, the system first enters the grounds-pushing mode. At this time, the second plunger assembly 8 returns to the first position, and the first plunger assembly 203 moves to its upper limit position. Then, in the grounds-pushing mode, the second plunger assembly 8 moves from the first position to the second position, pushing the coffee grounds to the right, thus achieving automatic grounds removal. Afterward, it can return to the initial mode for the next brewing.

[0083] The maintenance modes for coffee brewing equipment using the above-mentioned brewing device may include routine cleaning and maintenance mode and deep cleaning and maintenance mode.

[0084] In the routine cleaning and maintenance mode, since the first plunger assembly 203 of the brewing device is at the top of the cavity, i.e., the upper limit position, you can directly wipe the first plunger assembly 203 and the scraper 7 with a clean cloth or paper towel to clean the residual coffee grounds. Then you can press the cleaning button on the control panel of the coffee brewing equipment to perform an automatic cleaning. That is, it is not necessary to disassemble the brewing chamber assembly 2 for cleaning during routine cleaning and maintenance.

[0085] In deep cleaning and maintenance mode, the maintenance button on the control panel of the coffee brewing equipment can be pressed. The first drive assembly 102 will drive the lead screw structure 401 to move, causing the first plunger assembly 203 to move to the bottom of the cavity assembly 201. Then, the user can pinch the elastic mounting component 5 on the cavity assembly 201 with one hand, causing the buckle 501 of the elastic mounting component 5 to retract inward, thereby allowing the brewing cavity assembly 2 to detach from the brewer 1. The brewing cavity assembly 2 can be pulled straight out away from the brewer 1, thus separating the brewing cavity assembly 2 from the water pipe of the brewer 1, that is, separating the first connector 103 and the second connector 204. Then, the brewing cavity assembly 2 can be rinsed and cleaned separately. Furthermore, the brewing cavity assembly 2 can also be disassembled into two parts: the cavity assembly 201 and the first plunger assembly 203. This allows for cleaning not only the brewing cavity 202 of the cavity assembly 201 but also the sealing ring 214 of the first plunger assembly 203, achieving a better cleaning effect.

[0086] After cleaning the brewing chamber assembly 2 separately, simply place the brewing chamber assembly 2 on the top plane of the first connector 103 and roughly align it. Under the action of the guide structure in the installation cavity 101, the brewing chamber assembly 2 will be automatically guided and aligned when pushed in. The first connector 103 and the second connector 204 can be precisely inserted. At the same time, the coffee brewing equipment will also detect that the brewing chamber assembly 2 has been installed in place through the detection device 6, and the coffee brewing equipment's functions such as receiving powder, injecting water, drip filtering, and discharging residue will be restored in time.

[0087] This application also provides a coffee brewing apparatus, which includes the brewing device as described above.

[0088] This application achieves detachability of the brewing chamber assembly 2 by detachably installing it within the mounting cavity 101. This allows users to easily rinse or soak the disassembled assembly with water before reinstalling it back onto the brewer 1 for the next brewing. Furthermore, the brewing chamber assembly 2 can be further disassembled into a cavity assembly 201 and a first plunger assembly 203, facilitating deeper cleaning and maintenance and increasing user convenience. A liquid outlet channel is formed between the brewer 1 and the brewing chamber assembly 2 through the cooperation of the first connector 103 and the second connector 204, for discharging the brewed coffee liquid. This structure ensures a tight seal at the outlet, allowing the coffee liquid to be smoothly discharged through the outlet channel.

[0089] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. Those skilled in the art can make various modifications or equivalent substitutions to this application within the scope and nature of this application, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
