Description

Technical Field

[0001] This invention belongs to the field of coffee machine technology, and particularly relates to a coffee brewing system and coffee machine that are easy to clean. Background Technology

[0002] Existing fully automatic coffee machine brewing systems cannot be completely disassembled; typically, only the brewing head can be removed, making it difficult to completely disassemble the brewing components. This leads to difficulties in internal cleaning, resulting in odors and mold growth. For example, Chinese patent CN115568759A discloses a coffee machine brewing system, which includes a body, a brewing head assembly located at one end of the body's inner cavity, a screw assembly and brewing chamber assembly located at the other end of the inner cavity, and a coffee dispensing assembly located within the inner cavity. Because the body is fixed to the coffee machine as a whole, only the brewing head can be removed for cleaning. The remaining parts of the body are difficult to clean. As the coffee machine is used for longer, odors easily develop on the body, and bacteria can easily grow. Summary of the Invention

[0003] To address the aforementioned technical problems in the prior art, this invention provides a coffee brewing system and coffee machine that are easy to clean. This coffee brewing system allows for convenient disassembly and cleaning by the user.

[0004] The technical solution adopted in the embodiments of the present invention is as follows:

[0005] A coffee brewing system that is easy to clean includes a brewing base and a brewing chamber assembly. The brewing chamber assembly includes a sliding seat and a brewing head disposed on the sliding seat. The brewing head is detachably connected to the sliding seat. The coffee brewing system further includes:

[0006] A fixed bracket is disposed opposite to the brewing base;

[0007] A connecting rod assembly for connecting the brewing base and the fixed bracket to form a body, the body being detachably connected to the coffee machine, the sliding seat being connected to the connecting rod assembly and being movable relative to the connecting rod assembly in a direction toward or away from the brewing base to allow the brewing head to engage or disengage from the brewing base.

[0008] Furthermore, the coffee brewing system also includes a first coffee dispensing component and a second coffee dispensing component. The first coffee dispensing component is fixed on the sliding seat, and the second coffee dispensing component is fixed on the brewing base. When the brewing head is connected to the brewing base, the first coffee dispensing component and the second coffee dispensing component are in communication; when the brewing head is separated from the brewing base, the first coffee dispensing component and the second coffee dispensing component are disconnected. Positioning the coffee dispensing components on the machine body also facilitates the cleaning of any residual coffee liquid on the components.

[0009] Furthermore, the coffee brewing system also includes a connecting connector fixed to the brewing base. The connecting connector has a water supply channel and a coffee liquid channel. The outlet of the water supply channel communicates with the inner cavity of the brewing base, and the inlet of the coffee liquid channel communicates with the outlet of the second coffee dispensing assembly. When the machine body is placed on the coffee machine, the inlet of the water supply channel communicates with the water inlet connector on the coffee machine, and the outlet of the coffee liquid channel communicates with the coffee dispensing spout on the coffee machine. When the machine body is removed from the coffee machine, the inlet of the water supply channel disconnects from the water inlet connector on the coffee machine, and the outlet of the coffee liquid channel disconnects from the coffee dispensing spout on the coffee machine. This structure ensures that the coffee brewing system automatically connects to the water system of the coffee machine when placed on it.

[0010] Furthermore, the connecting rod assembly comprises multiple parallel rods, the first ends of which are detachably connected to the outer periphery of the brewing base, and the second ends of which are detachably connected to the outer periphery of the fixed bracket. This structure is simple and prevents the machine body from becoming loose and deformed during disassembly.

[0011] Furthermore, the outer periphery of the sliding seat is provided with multiple guide grooves, each corresponding to one of the multiple rods. The length direction of the rod is consistent with the moving direction of the sliding seat, and the rod fits against the groove wall. This structure not only facilitates the installation of the sliding seat but also facilitates its movement.

[0012] Furthermore, the coffee brewing system also includes a locking mechanism on the machine body. The locking mechanism includes a pull rod, a locking rod, and a transmission mechanism connecting the pull rod and the locking rod, all connected to the machine body. The pull rod is movable relative to the machine body and, through the transmission mechanism, drives the locking rod to move to engage or disengage with a fastener on the coffee machine, thereby installing the machine body onto or removing it from the coffee machine. This structure is simple and easy to implement.

[0013] Furthermore, the locking rod is slidably connected to the brewing base, and the pull rod is rotatably connected to the brewing base. The transmission mechanism includes a crank-slider assembly and a transmission rod. The pull rod is connected to the crank in the crank-slider assembly to drive its rotation. One end of the transmission rod is rotatably connected to the slider in the crank-slider assembly, and the other end of the transmission rod is rotatably connected to the locking rod. The mechanical linkage structure results in a more compact spatial layout and smaller size.

[0014] A coffee machine includes a main unit and a coffee brewing system as described in any of the preceding embodiments, the main unit having a coffee brewing chamber for accommodating the coffee brewing system.

[0015] Furthermore, the main unit is equipped with a motor assembly, which includes a first push rod and a second push rod that are respectively movable in directions toward and away from the brewing base. When the body of the coffee brewing system is placed on the coffee machine, the sliding seat can be connected to the first push rod, and the brewing head can be connected to the second push rod. When the body of the coffee brewing system is removed from the coffee machine, the sliding seat can be separated from the first push rod, and the brewing head can be separated from the second push rod. This structure separates the motor assembly from the existing coffee brewing system and places it on the main unit of the coffee machine, facilitating the disassembly and installation of the coffee brewing system.

[0016] Furthermore, the host is equipped with a reset micro switch assembly, a powder receiving micro switch assembly, and a powder pressing micro switch assembly, which are electrically connected to the controller respectively; the controller is also electrically connected to the motor assembly; the sliding seat has a reset position, a powder receiving position, and a powder pressing position in its moving direction. In the reset position, the sliding seat triggers the reset micro switch assembly; in the powder receiving position, the sliding seat triggers the powder receiving micro switch assembly; in the powder pressing position, the sliding seat triggers the powder pressing micro switch assembly. When the reset micro switch assembly, the powder receiving micro switch assembly, and the powder pressing micro switch assembly are triggered, they can generate control signals respectively. After receiving the control signals, the controller controls the motor assembly to stop.

[0017] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows:

[0018] The coffee brewing system provided by this invention allows the main body to be detached from the coffee machine, and the brewing head to be detached from the sliding seat. This makes it convenient for users to disassemble and clean the entire coffee brewing system, avoiding the occurrence of odors and thus preventing a bad user experience. Attached Figure Description

Detailed Implementation

[0045] To enable those skilled in the art to better understand the technical solutions of the embodiments of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] For ease of description below, the end of the coffee brewing system where the brewing base 10 is located is defined as the front end, and the end of the brewing chamber assembly 20 is defined as the rear end. The movement of the brewing chamber assembly 20 toward the brewing base 10 is defined as moving forward or forward, and the movement of the brewing chamber assembly 20 toward the direction away from the brewing base 10 is defined as moving backward or backward.

[0047] This invention provides an easy-to-clean coffee brewing system, which mainly includes a brewing base 10 and a brewing chamber assembly 20. For example... Figure 1 and Figure 2 As shown, the brewing chamber assembly 20 includes a sliding seat 201 and a brewing head 200 disposed on the sliding seat 201. The brewing seat 10 is used to communicate with the water system of the coffee machine. The brewing head 200 has a brewing chamber and a pressure head 205 that can move within the brewing head 200. The brewing chamber is used to hold coffee grounds, and the pressure head 205 can compress the coffee grounds in the brewing chamber to form a coffee cake. The brewing head 200 can be connected to or separated from the brewing seat 10. When the brewing head 200 is connected to the brewing seat 10, the brewing water in the water system of the coffee machine can enter the brewing chamber in the brewing head 200 to brew the coffee. After the coffee is brewed, the brewing head 200 is separated from the brewing seat 10. The specific structure of the brewing chamber assembly 20 and the brewing seat 10 is prior art and will not be described in detail.

[0048] like Figure 1 , Figure 2 as well as Figure 3 As shown, the coffee brewing system of this embodiment also includes a fixed bracket 30, a connecting rod assembly 40, and a locking mechanism 50. The fixed bracket 30 is disposed opposite to the brewing base 10, and the connecting rod assembly 40 connects the brewing base 10 and the fixed bracket 30 to form the body of the coffee brewing system. This body is detached from the coffee machine, and can be removed from the coffee machine before cleaning.

[0049] The sliding seat 201 is connected to the connecting rod assembly 40, and the sliding seat 201 can move relative to the connecting rod assembly 40 in a direction that is closer to or farther away from the brewing base 10.

[0050] When the sliding seat 201 moves forward, the brewing head 200 on it can dock with the brewing base 10; when the sliding seat 201 moves backward, the brewing head 200 on it can separate from the brewing base 10.

[0051] like Figure 3 As shown, the brewing head 200 is also detachably connected to the sliding base 201, so that the brewing head 200 can be removed and cleaned separately when the machine is removed from the coffee machine.

[0052] The coffee brewing system provided in this embodiment can be easily disassembled from the coffee machine, and the brewing head 200 can be removed from the sliding seat 201. This allows users to easily disassemble and clean the coffee brewing system as a whole, avoiding the occurrence of odors and thus avoiding a bad user experience.

[0053] like Figure 4As shown, in some embodiments, the sliding seat 201 has a cavity for placing the brewing head 200. Slots are provided at the top and bottom of the cavity. Pins 203 are provided at the top and bottom of the brewing head 200, respectively. Both pins 203 can move up and down vertically. A return spring 204 is provided inside the brewing head 200, with both ends of the return spring 204 abutting against the pins 203. Pressing the pins 203 compresses the return spring 204. When installing the brewing head 200, both pins 203 are pressed simultaneously. After the brewing head 200 is placed in the cavity, the pins 203 are released. Under the force of the return spring 204, the two pins 203 can be inserted into the slots on the cavity, thereby connecting the brewing head 200 to the sliding seat 201. To remove the brewing head 200, press the two pins 203 again to move them out of the slots, and then pull out the brewing head 200. This connection mechanism makes it easy to disassemble the brewing head 200.

[0054] In some embodiments, the coffee brewing system further includes a first coffee dispensing assembly 60 and a second coffee dispensing assembly 70. The two coffee dispensing assemblies can work together to discharge the coffee liquid brewed in the brewing chamber of the brewing head 200.

[0055] like Figure 5 As shown, the first coffee dispensing assembly 60 is fixed on the sliding seat 201, and its inlet is used to communicate with the brewing chamber inside the brewing head 200. The first coffee dispensing assembly 60 has a first outlet and a second outlet that can communicate with its inlet. Figure 6 As shown, the second coffee dispensing component 70 is fixed on the brewing base 10, and it has a liquid inlet and a third liquid outlet that are interconnected.

[0056] When the sliding seat 201 is moved to align the brewing head 200 with the brewing base 10, the first outlet of the first coffee dispensing assembly 60 connects with the inlet of the second coffee dispensing assembly 70. Simultaneously, the inlet of the first coffee dispensing assembly 60 connects with its first outlet, allowing coffee to be discharged through the third outlet of the second coffee dispensing assembly 70 for the user to drink. When the sliding seat 201 is moved to separate the brewing head 200 from the brewing base 10, the inlet of the first coffee dispensing assembly 60 disconnects from its first outlet but connects with its second outlet to discharge any remaining coffee in the brewing chamber. In this embodiment, the two coffee dispensing assemblies are respectively mounted on the main body, allowing for cleaning of both assemblies when the main body is removed from the coffee machine.

[0057] The specific structures of the first coffee dispensing component 60 and the second coffee dispensing component 70 in this embodiment are existing technologies and will not be described in detail here.

[0058] like Figure 5 and Figure 6 As shown, in this embodiment, the first coffee dispensing component 60 is fixed on the outer peripheral wall of the sliding seat 201, and the second coffee dispensing component 70 is fixed on the outer peripheral wall of the brewing seat 10, thereby facilitating the cleaning of the coffee dispensing components.

[0059] Preferably, the first coffee dispensing assembly 60 is detachably connected to the sliding seat 201, for example, by fixing it to the sliding seat 201 with screws. Similarly, the second coffee dispensing assembly 70 is also detachably connected to the sliding seat 201, so that the two coffee dispensing assemblies can be further disassembled for cleaning, thereby improving the cleaning effect.

[0060] Because the coffee brewing system needs to be connected to the water system on the coffee machine, it is necessary to ensure that the connection to the water system is broken during both disassembly and installation. For example... Figure 13 As shown, in some embodiments, the coffee brewing system further includes a connecting joint 80 fixed on the brewing base 10, the connecting joint 80 having a water supply channel and a coffee liquid channel. The outlet of the water supply channel is connected to the brewing chamber of the brewing base 10, and the inlet of the coffee liquid channel is connected to the outlet of the second coffee dispensing assembly 70.

[0061] Continue as Figure 13 As shown, the coffee machine is equipped with a water inlet connector 92 and a coffee outlet spout 91. When the coffee brewing system is placed on the coffee machine, the inlet of the water supply channel on the connector 80 is connected to the water inlet connector 92 on the coffee machine, and the outlet of the coffee liquid channel is connected to the coffee outlet spout 91 on the coffee machine. This ensures that the water for brewing coffee can automatically flow into the brewing head 200 for brewing, and the brewed coffee can be discharged through the two coffee dispensing components and the coffee outlet spout 91. When the machine is removed from the coffee machine, the inlet of the water supply channel is disconnected from the water inlet connector 92 on the coffee machine, and the outlet of the coffee liquid channel is disconnected from the coffee outlet spout 91 on the coffee machine. At the same time, the water inlet connector 92 and the coffee outlet spout 91 can also automatically close to prevent leakage of brewing water and coffee liquid.

[0062] like Figure 2 and Figure 3 As shown, in some embodiments, the connecting rod assembly 40 includes multiple parallel rods, which can be steel pipes. The first end of each rod is connected to the outer periphery of the brewing base 10, and the second end of each rod is connected to the outer periphery of the fixed bracket 30. In this way, the main body formed by the multiple rods, the brewing base 10 and the fixed bracket 30 has high strength, which can ensure the structural reliability of the entire coffee brewing system and prevent loosening during disassembly.

[0063] Preferably, each rod is connected to the brewing base 10 and the fixed bracket 30 by bolts, thereby facilitating the assembly of the main body.

[0064] Furthermore, the outer periphery of the sliding seat 201 in this embodiment is provided with a plurality of guide grooves 202 that correspond one-to-one with a plurality of rods. The length direction of the rods is consistent with the moving direction of the sliding seat 201, and the sliding seat 201 can move along the length direction of the rods.

[0065] like Figure 4 As shown, the guide groove 202 on the sliding seat 201 is formed by the inward indentation of its outer peripheral wall. When the sliding seat 201 is placed between multiple rods, each rod is in contact with the groove wall of the corresponding guide groove 202. The multiple rods can restrict the sliding seat 201 to move only in the direction of approaching or moving away from the brewing seat 10.

[0066] like Figure 7 As shown, the coffee brewing system of this embodiment also includes a locking mechanism 50 disposed on the machine body. The coffee machine has a latch 97, and the locking mechanism 50 is used to engage with the latch 97 on the coffee machine to allow the machine body to be detachably connected to the coffee machine. That is, the locking mechanism 50 enables the connection and separation of the machine body from the coffee machine.

[0067] In some embodiments, the locking mechanism 50 provided on the main body includes a pull rod 53, a locking rod 51 and a transmission mechanism 54 that are respectively connected to the main body.

[0068] The main body of the coffee machine is provided with a fastener 97. In this embodiment, the pull rod 53 can move relative to the machine body and drive the locking rod 51 to move together through the transmission mechanism 54 to connect with the fastener 97 on the coffee machine, thereby fixing the machine body to the main unit 90 of the coffee machine, or drive the locking rod 51 to move together to separate from the fastener 97 on the coffee machine, so that the machine body can be removed from the main unit 90 of the coffee machine.

[0069] In this embodiment, the locking mechanism 50 can be mounted on the fixed bracket 30 of the machine body or on the brewing base 10. Preferably, the locking mechanism 50 is mounted on the brewing base 10. Figure 8 and Figure 9 As shown, the locking lever 51 is slidably connected to the brewing base 10 and can move relative to the brewing base 10 to connect or disconnect with the latch 97 on the main unit 90. The pull rod 53 is rotatably connected to the brewing base 10 and can rotate relative to the brewing base 10. The transmission mechanism 54 is used to convert the rotation of the pull rod 53 into the movement of the locking lever 51.

[0070] In some embodiments, the transmission mechanism 54 can be a linkage structure. For example, such as... Figure 7As shown, the transmission mechanism 54 includes a crank-slider assembly 542 and a transmission rod 540. The crank in the crank-slider assembly 542 is connected to the pull rod 53, and the rotation of the pull rod 53 can drive the crank to rotate. The slider in the crank-slider assembly 542 is slidably connected to the brewing base 10. One end of the transmission rod 540 is rotatably connected to the slider, and the other end of the transmission rod 540 is rotatably connected to the locking rod 51. Thus, when the pull rod 53 rotates, it can drive the locking rod 51 to move on the sliding base 201.

[0071] Furthermore, the brewing base 10 in this embodiment is also provided with a guide rod 541. The first end of the guide rod 541 is inserted into the positioning hole 800 on the connecting joint 80, and the other end is fixed to the brewing base 10 by bolts. The extending direction of the guide rod 541 is perpendicular to the moving direction of the locking rod 51. The slider in the crank slider assembly 542 is slidably disposed on the guide rod 541 and can move along the guide rod 541.

[0072] Preferably, the guide rod 541 is provided with a first limiting part (not shown in the figure) and a second limiting part (not shown in the figure) spaced apart. When the pull rod 53 rotates in the first direction until the locking rod 51 is connected to the buckle 97, the slider can abut against the first limiting part to restrict the slider from moving further; when the pull rod 53 rotates in the second direction opposite to the first direction until the locking rod 51 is separated from the buckle 97, the slider can abut against the second limiting part to restrict the slider from moving further. By having the slider abut against the two limiting parts on the guide rod 541 respectively, the user can easily know whether the locking rod 51 is engaged or disengaged from the buckle 97.

[0073] It should be noted that the first direction in this embodiment can be understood as clockwise, and the second direction is counterclockwise, or the first direction can be understood as counterclockwise, and the second direction is clockwise.

[0074] Preferably, the brewing base 10 in this embodiment has a receiving cavity. The locking rod 51 and the transmission mechanism 54 are respectively disposed in the receiving cavity, and the brewing base 10 is provided with a through hole 100 connecting the brewing cavity and the outside.

[0075] like Figure 9 As shown, when the lever 53 rotates in the first direction, the locking lever 51 can move relative to the brewing base 10 so that a portion of it extends out through the through hole 100, and the portion extending out can be connected to the fastener 97 on the body.

[0076] like Figure 8 As shown, when the lever 53 rotates in the second direction, the locking lever 51 can retract completely into the receiving cavity, thereby separating from the latch 97 on the body.

[0077] This invention also provides a coffee machine, such as... Figure 10As shown, the coffee machine includes a main unit 90 and a coffee brewing system that is easy to clean, as described in any of the above embodiments. The coffee brewing system is detachably connected to the main unit 90.

[0078] like Figure 11 As shown, the main unit 90 has a coffee brewing chamber 98 that accommodates a coffee brewing system, which can be placed inside the coffee brewing chamber 98.

[0079] Preferably, the coffee brewing chamber 98 has a fastener 97 on its chamber wall. When the coffee brewing system is placed inside the coffee brewing chamber 98, the locking mechanism 50 on it can cooperate with the fastener 97 to fix the coffee brewing system inside the coffee brewing chamber 98.

[0080] like Figure 2 and Figure 12 As shown, in some embodiments, the main unit 90 is also provided with a motor assembly 96 for driving the brewing chamber assembly 20 to move. When the coffee brewing system is placed on the main unit 90, the motor assembly 96 is opposite to the brewing chamber assembly 20. The motor assembly 96 has a first push rod 960 and a second push rod 961 that can move back and forth in the front-rear direction. The first push rod 960 is used to connect with the sliding seat 201 to control the movement of the sliding seat 201 and the brewing head 200. The second push rod 961 is used to connect with the pressure head 205 in the brewing head 200. When the first push rod 960 drives the sliding seat 201 and the brewing head 200 forward to the position where coffee powder needs to be added, the second push rod 961 and the pressure head 205 remain stationary. After the sliding seat 201 and the brewing head 200 move to the position where the brewing chamber needs to receive coffee powder, coffee powder can be added into the brewing chamber in the brewing head 200. Then, by controlling the second push rod 961 to move forward, the pressure head 205 can be used to squeeze the coffee powder to form a coffee cake.

[0081] like Figure 2 and Figure 3As shown, the ends of the first push rod 960 and the second push rod 961 are respectively provided with connecting grooves 962. The middle part of the fixed bracket 30 on the main body is provided with a through hole 300. The sliding seat 201 and the brewing head 200 facing the motor assembly 96 respectively have protrusions that can pass through the through hole 300. Before the coffee brewing system is installed on the main unit 90, the sliding seat 201 and the brewing head 200 can be moved in advance so that their protrusions pass through the through hole 300 on the fixed bracket 30. When the coffee brewing system is installed on the main unit 90, the protrusions on the sliding seat 201 and the brewing head 200 can be inserted into the connecting grooves 962 of the corresponding push rods respectively, thereby realizing the connection with the corresponding push rods. When the coffee brewing system is removed from the main unit 90, the protrusions on the sliding seat 201 and the brewing head 200 can then be disengaged from the connecting grooves 962 of the corresponding push rods respectively. This structure facilitates the connection between the brewing head 200 and the sliding seat 201 in the coffee brewing system and the motor assembly 96, respectively.

[0082] like Figure 14 and Figure 15 As shown, in some embodiments, the host 90 is provided with a reset micro switch assembly 93, a powder receiving micro switch assembly 94, and a powder pressing micro switch assembly 95, which are respectively electrically connected to the controller. The controller is also connected to the motor assembly 96. When these micro switches are triggered, they can generate control signals respectively. After receiving the generated control signals, the controller can control the first push rod 960 of the motor assembly 96 to stop moving. When the trigger of these micro switches is activated, the controller can control the first push rod 960 of the motor assembly 96 to move forward again.

[0083] In this embodiment, the sliding seat 201 has three positions in its moving direction: a reset position, a powder receiving position, and a powder pressing position. The reset position corresponds to the rearmost end of the main body, where the sliding seat 201 is close to the fixed bracket 30. The powder pressing position corresponds to the frontmost end of the main body, where the sliding seat 201 is close to the brewing base 10, and the brewing head 200 is connected to the brewing base 10. The powder receiving position corresponds to the middle of the main body, where coffee powder can be added to the brewing head 200. The reset microswitch assembly 93, the powder receiving microswitch assembly 94, and the powder pressing microswitch assembly 95 are respectively disposed at these three positions.

[0084] In this embodiment, after the coffee brewing system is placed in the coffee brewing chamber 98 on the main unit 90, when the sliding seat 201 moves to the reset position, the sliding seat 201 can trigger the reset micro switch assembly 93, thereby controlling the first push rod 960 of the motor assembly 96 to stop moving; when the sliding seat 201 moves forward to the powder receiving position, the sliding seat 201 can trigger the powder receiving micro switch assembly 94, thereby controlling the first push rod 960 of the motor assembly 96 to stop moving again, and the sliding seat 201 can perform powder adding work at this position; when the sliding seat 201 finishes adding coffee powder and moves to the powder receiving position, the brewing base 10 can trigger the powder receiving micro switch assembly 94, thereby controlling the first push rod 960 of the motor assembly 96 to stop moving again.

[0085] like Figure 14 and Figure 15 As shown, in some embodiments, the reset microswitch assembly 93 and the powder-receiving microswitch assembly 94 are respectively located outside the coffee brewing chamber 98 on the main unit 90, and these two micro-coffee components respectively include a microswitch mounting bracket A930, a lever A931, a spring A932, and a microswitch A933. The microswitch mounting bracket A930 and the microswitch A933 are fixed on the main unit 90, the spring A932 is mounted on the microswitch mounting bracket A930, one end of the lever A931 extends into the coffee brewing chamber 98, and the other end abuts against the spring A932. When the sliding seat 201 moves to the reset position and the powder-receiving position respectively, it can push the lever A931 to squeeze the spring A932. During the process of squeezing the spring A932, the lever A931 can trigger the microswitch A933. At this time, the microswitch generates a control signal and sends the control signal to the controller. The controller receives the control signal and controls the sliding seat 201 to stop moving. When the sliding seat 201 is removed from the reset position and the powder receiving position respectively, the lever A931 will return to the initial position under the elastic force of the spring A932.

[0086] Furthermore, the powder pressing micro switch assembly 95 in this embodiment includes a micro switch mounting bracket B950, a lever B951, a spring B952, and a micro switch B953. Its movement principle is the same as that of the reset micro switch assembly 93, except that the lever B951 is pushed by the brewing base 10. When the brewing head 200 is connected to the brewing base 10, the brewing base 10 will also move forward a certain distance. At this time, the brewing base 10 will push the lever B951 to trigger the micro switch B953 to generate a control signal.

The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
