[0034] It can be understood that the principle of brewing the powder material to obtain the beverage liquid by the beverage machine 100 can be the same as or similar to the general principle of brewing the coffee powder to obtain the coffee liquid in the coffee machine in the related art, which will not be described herein.

[0035] Please refer to Figure 2 and Figure 3 In an embodiment, the beverage machine 100 can include a machine body 101, a powder grinding device 102, and a brewing device 103 (as shown in Figure 11 ).

[0036] The machine body 101 can include a frame and a shell, and the shell can cover the outer side of the frame and be fixedly connected with the frame. The frame can provide mounting positions for constituent components of the beverage machine 100 and support the shell.

[0037] The powder grinding device 102 can be located in the machine body 101 and fixedly connected with the machine body 101. The powder grinding device 102 can include a powder grinding mechanism 1021 and a powder outlet mechanism 1022. The powder grinding mechanism 1021 can receive the bean material and grind the bean material to obtain the powder material. For example, the powder grinding mechanism 1021 and the powder outlet mechanism 1022 can be arranged along a first horizontal direction; alternatively, the powder grinding mechanism 1021 and the powder outlet mechanism 1022 can have other positional relationships, which are not limited herein.

[0038] The powder grinding mechanism 1021 can be provided with a first discharge port 10211 on a side facing the powder outlet mechanism 1022. The powder outlet mechanism 1022 can be in communication with the first discharge port 10211, and the powder material obtained by grinding by the powder grinding mechanism 1021 can be removed from the powder grinding mechanism 1021 through the first discharge port 10211 and enter the powder outlet mechanism 1022.

[0039] The brewing device 103 can be located below the powder grinding device 102. The powder material in the powder outlet mechanism 1022 can enter the brewing device 103 from the powder outlet mechanism 1022. The brewing device 103 can brew the powder material to obtain the beverage liquid. The brewing device 103 can be provided through the machine body 101, or the machine body 101 can be provided with a liquid outlet (not shown in the figure) corresponding to the brewing device 103, so that the beverage liquid produced by the brewing device 103 can flow out of the machine body 101, and the user can receive the beverage liquid flowing out of the machine body 101 by using a container.

[0040] In the embodiments of the present application, the length direction, the width direction, and the height direction of the powder grinding device 102 can be defined as the first direction, the second direction, and the third direction, respectively.

Wherein, the beverage machine 100 and the constituent components thereof can have a top and a bottom oppositely arranged in the third direction.

[0041] It can be understood that the discharging direction of the powder in the powder discharging mechanism 1022 can coincide with the third direction, and the powder can move to the bottom of the powder discharging mechanism 1022 under the action of gravity and enter the powder grinding device 102 located below the powder discharging mechanism 1022.

[0042] In the embodiments of the present application, the working principle and structure of the powder grinding mechanism 1021 can be the general principle and structure in the related field respectively, which will not be repeated here; at the same time, the working principle and structure of the brewing device 103 can be the general principle and structure in the related field respectively, which will not be repeated here.

[0043] In the embodiments of the present application, the fixing mode when fixedly installed and fixedly connected is not specifically limited. For example, the fixing mode can include, but is not limited to, bolt fixing, screw fixing, welding fixing, one-piece fixing and buckle fixing.

[0044] Please refer to Figure 4 In some embodiments, a powder discharging channel 10 can be formed in the powder discharging mechanism 1022, the powder discharging channel 10 can extend along the third direction, and the length of the powder discharging channel 10 in the third direction is adjustable. The powder discharging channel 10 can be in communication with the first discharging port 10211 to receive the powder from the first discharging port 10211, and the powder can fall in the powder discharging channel 10 under the action of gravity, thereby moving to the brewing device 103.

[0045] The powder discharging mechanism 1022 can include a housing 20, a powder receiving assembly 30 and a lifting assembly 40. The powder discharging channel 10 can include a first powder channel 11 and a second powder channel 12.

[0046] A first space 21 can be formed in the housing 20 Figure 7The bottom of the shell 20 can be provided with a discharge opening 22. The discharge opening 22 can be in communication with the first space 21. The powder receiving assembly 30 and the lifting assembly 40 are at least partially received in the first space 21. The powder receiving assembly 30 can be fixedly connected to the shell 20. The powder receiving assembly 30 can be provided with an inlet opening 31 on a side close to the grinding mechanism 1021 in the first direction. The inlet opening 31 can be in communication with the first discharge opening 10211. A first powder channel 11 can be provided in the powder receiving assembly 30. The first powder channel 11 can extend along the third direction and penetrate the bottom of the powder receiving assembly 30. The opening of the first powder channel 11 at the bottom can be correspondingly arranged with the discharge opening 22. The first powder channel 11 can be in communication with the inlet opening 31. Powder can enter the first powder channel 11 through the inlet opening 31.

[0047] Please refer to Figure 5 and Figure 6 A second powder channel 12 can be provided in the lifting assembly 40 and extend along the third direction. The bottom of the lifting assembly 40 can be provided with a second discharge opening 41. The second discharge opening 41 can be in communication with the second powder channel 12. The powder receiving assembly 30 can be partially received in the second powder channel 12. The lifting assembly 40 can be sleeved on the powder receiving assembly 30. Powder in the first powder channel 11 can enter the second powder channel 12 under the action of gravity. Powder in the second powder channel 12 can be removed from the second powder channel 12 through the second discharge opening 41.

[0048] The lifting assembly 40 can be movably connected to the powder receiving assembly 30 in the third direction. When the lifting assembly 40 is lowered, the bottom of the lifting assembly 40 can extend out of the shell 20 from the discharge opening 22. The volume of the powder receiving assembly 30 received in the second powder channel 12 is reduced. The space where the second powder channel 12 and the first powder channel 11 overlap in the third direction is reduced. Thus, the length of the powder outlet channel 10 formed by the cooperation of the first powder channel 11 and the second powder channel 12 can be increased. When the lifting assembly 40 is raised, the bottom of the lifting assembly 40 can enter the shell 20 through the discharge opening 22. The volume of the powder receiving assembly 30 received in the second powder channel 12 is increased. The space where the second powder channel 12 and the first powder channel 11 overlap in the third direction is increased. Thus, the length of the powder outlet channel 10 formed by the cooperation of the first powder channel 11 and the second powder channel 12 can be reduced.

[0049] It can be understood that when the grinding mechanism 1021 is not working, the lifting assembly 40 can be located in the first space 21. There is a spacing distance between the bottom of the powder outlet mechanism 1022 and the brewing device 103.

[0050] When the grinding mechanism 1021 works and generates powder, the lifting assembly 40 can move out of the shell 20 through the discharge opening 22, and the bottom of the lifting assembly 40 can be close to the brewing device 103, so as to shorten the distance from the brewing device 103 or abut against the brewing device 103. The powder generated by the grinding mechanism 1021 can enter the powder discharging mechanism 1022 through the first discharge port 10211, and the powder can sequentially pass through the feeding port 31, the first powder channel 11, the second powder channel 12 and the second discharge port 41, so as to move out of the powder discharging mechanism 1022 and enter the brewing device 103.

[0051] In this way, the movement of the lifting assembly 40 in the third direction can realize the extension of the powder discharging channel 10, so that the powder discharging channel 10 can cover the space between the grinding mechanism 1021 and the brewing device 103, and the movement path of the powder can be closed. The powder entering the brewing device 103 through the extended powder discharging channel 10 can reduce the splashing of the powder due to the lifting assembly 40 moving away from the brewing device 103, and can reduce the situation that the powder splashes outside the brewing device 103 and falls on other mechanisms inside the machine body 101 or other mechanisms inside the machine body 101, so as to improve the cleanliness of the surfaces of the components in the machine body 101 and reduce the difficulty of cleaning the beverage machine 100 for the user.

[0052] It can be understood that the shell 20 can be fixedly connected with the machine body 101, so as to realize the relative fixation of the powder discharging mechanism 1022 and the machine body 101.

[0053] It can be understood that the outer side of the powder receiving assembly 30 can be provided with a sealing ring 32, and the sealing ring 32 can abut against the inner wall of the second powder channel 12, so as to realize the sealing connection between the lifting assembly 40 and the powder receiving assembly 30, and to realize the blocking of the opening at the top of the lifting assembly 40 and the space outside the powder receiving mechanism during the movement of the lifting assembly 40, so as to reduce the probability of powder leakage from the connection between the lifting assembly 40 and the powder receiving assembly 30.

[0054] Please refer to Figure 7 In some embodiments, the powder discharging mechanism 1022 can further include a movable door 50. The movable door 50 can be arranged at the discharge opening 22, and one side of the movable door 50 can be rotatably connected to the shell 20. The movable door 50 and the shell 20 can be connected with an elastic member 51. The elastic member 51 can have a pre-tightening force, so as to maintain the shielding of the discharge opening 22 by the movable door 50, and to close the discharge opening 22.

[0055] When the powder outlet channel 10 is extended, the bottom of the lifting assembly 40 can push the movable door 50 to rotate, so as to expose the discharge opening 22, thereby opening the discharge opening 22; the lifting assembly 40 can extend from the opened discharge opening 22. At this time, the elastic member 51 can be compressed and deformed; when the lifting assembly 40 moves into the first space 21, the elastic member 51 can drive the movable door 50 to rotate through the elastic force generated by deformation, so as to increase the shielding of the discharge opening 22, and finally close the discharge opening 22.

[0056] It can be understood that the rotatable connection can be achieved by a rotating connecting member, which is a connection mode that can cause relative rotation of two components. In the embodiments of the present application, the type of rotating connecting member is not specifically limited. For example, the rotating connecting member can be, but is not limited to, a pin shaft, a bearing or a hinge.

[0057] In the embodiments of the present application, the type of elastic member 51 is not specifically limited. For example, the elastic member 51 can be, but is not limited to, a torsion spring.

[0058] For example, one side of the movable door 50 can be provided with a connecting shaft 52, the connecting shaft 52 can be fixedly connected with the shell 20, and the movable door 50 can rotate around the connecting shaft 52, thereby achieving the rotatable connection between the movable door 50 and the shell 20. The elastic member 51 can be a torsion spring, the elastic member 51 can be sleeved on the connecting shaft 52, and the two ends of the elastic member 51 can respectively abut against one side of the movable door 50 away from the lifting assembly 40 and the outer side of the shell 20.

[0059] It can be understood that after the powder in the powder outlet channel 10 enters the brewing device 103 through the second discharge port 41, and before the brewing device 103 brews the powder, the lifting assembly 40 can be retracted into the first space 21, at this time, the movable door 50 can be closed under the driving of the elastic member 51, thereby blocking the water vapor generated when the brewing device 103 brews the powder, reducing the situation that the water vapor enters the powder outlet channel 10 and causes the powder remaining in the powder outlet channel 10 to be caked, and reducing the situation that the water vapor is transmitted to the grinding mechanism 1021 through the powder outlet channel 10, causing the powder remaining in the grinding mechanism 1021 to be caked, thereby reducing the situation that the caked powder enters the brewing device 103 when the grinding device 102 produces powder and transmits it to the brewing device 103 in the future, and reducing the influence of the caked powder on the quality of the beverage liquid brewed by the brewing device 103.

[0060] In some embodiments, the housing 20 can include a first housing portion 23 and a second housing portion 24. The first housing portion 23 and the second housing portion 24 can be oppositely arranged in the first direction and fixedly connected. The first housing portion 23 can be located on a side of the second housing portion 24 away from the grinding mechanism 1021. The first housing portion 23 and the second housing portion 24 can jointly form the first space 21, and can be respectively located on two sides of the powder receiving assembly 30 in the first direction and can be respectively located on two sides of the lifting assembly 40 in the first direction.

[0061] It can be understood that the first housing portion 23 and the second housing portion 24 can cooperate to form the discharge opening 22, and the movable door 50 can be connected to the first housing portion 23 and the second housing portion 24 at the same time.

[0062] For example, the first housing portion 23 and the second housing portion 24 can be fixedly connected by buckles and / or screws, and personnel can separate the first housing portion 23 and the second housing portion 24 by releasing the buckles and / or unscrewing the screws to maintain the powder discharging mechanism 1022.

[0063] In some embodiments, the powder receiving assembly 30 can include a powder channel portion 33 and an interface portion 34. The powder channel portion 33 can be cylindrical and can extend along the third direction. The first powder channel 11 is formed in the powder channel portion 33 and can extend through the powder channel portion 33 along the third direction. The powder channel portion 33 can be received in the first space 21. The lifting assembly 40 can be sleeved on the powder channel portion 33.

[0064] The interface portion 34 can be protruded on a side of the powder channel portion 33 facing the grinding mechanism 1021 in the first direction, and the feed inlet 31 is formed in the interface portion 34. The feed inlet 31 can extend along the first direction and penetrate through an inner wall of the first powder channel 11 near the grinding mechanism 1021, so as to realize the communication between the feed inlet 31 and the first powder channel 11.

[0065] The second housing portion 24 can be formed with a powder receiving opening 25, which communicates with the first space 21. The powder receiving opening 25 can be correspondingly arranged with the interface portion 34, and the interface portion 34 can pass through the powder receiving opening 25 in the first direction, so as to extend out of the housing 20, so that the material receiving port on the interface portion 34 can be correspondingly arranged with and communicated with the first discharge opening 10211.

[0066] For example, the interface portion 34 can be fixedly connected with a part of the grinding mechanism 1021 where the first discharge opening 10211 is formed by buckles, so as to realize the corresponding arrangement and communication between the first discharge opening 10211 and the material receiving port, and realize the relative fixation between the grinding mechanism 1021 and the powder discharging mechanism 1022.

[0067] It can be understood that the lifting assembly 40 can be provided with a notch 42 for avoiding the interface portion 34, so as to avoid the interference of the interface portion 34 structure on the movement of the lifting assembly 40 in the third direction.

[0068] It can be understood that the sealing ring 32 can be sleeved outside the powder channel portion 33 and abut against the inner wall of the second powder channel 12, so as to realize the sealed connection of the powder receiving assembly 30 and the lifting assembly 40.

[0069] It can be understood that the sealing ring 32 can be sleeved outside the powder channel portion 33 and abut against the inner wall of the second powder channel 12, so as to realize the sealed connection of the powder receiving assembly 30 and the lifting assembly 40. Figure 8 In some embodiments, the top of the powder receiving assembly 30 can be provided with a mounting opening 35, and the mounting opening 35 can be formed by the top of the powder channel portion 33 and the top of the interface portion 34. The mounting opening 35 can be in communication with the first powder channel 11.

[0070] The powder outlet mechanism 1022 can further include a shielding assembly 60. The shielding assembly 60 can be accommodated in the first space 21, the shielding assembly 60 can be connected with the powder receiving assembly 30, and can extend into the first powder channel 11 through the mounting opening 35. The shielding assembly 60 can shield the feeding opening 31 on one side in the first direction, and guide the powder entering the first powder channel 11 from the feeding opening 31 to move towards the second discharge opening 41.

[0071] The shielding assembly 60 can include a mounting frame 61 and a shielding piece 62. The mounting frame 61 can be located on the mounting opening 35, and can be fixedly connected with the powder channel portion 33 and / or the interface portion 34. The shielding piece 62 can be fixedly connected to the mounting frame 61, and can extend into the first powder channel 11. The shielding piece 62 can extend along the mounting opening 35 towards the second discharge opening 41, and the bottom of the shielding piece 62 can be arc-shaped. The shielding piece 62 can shield the feeding opening 31 in the first direction, and is spaced apart from the inner wall of the first powder channel 11 near the interface portion 34.

[0072] In this way, the powder entering the first powder channel 11 through the feeding opening 31 can collide with the shielding piece 62, the shielding piece 62 can block the movement of the powder in the first powder channel 11 in the direction away from the feeding opening 31, and can guide the powder to move towards the second discharge opening 41 along the extension direction of the shielding piece 62, so as to improve the smoothness of the powder moving to the second discharge opening 41.

[0073] Meanwhile, the baffle 62 can be arranged in a spaced-apart manner from the inner wall of the first powder channel 11 on the side of the interface portion 34 away from the first direction. In this way, the powder cannot continue to move away from the feed opening 31 in the first direction after colliding with the baffle 62, so that the probability of the powder adhering to the inner walls of the first powder channel 11 and the second powder channel 12 can be reduced. Some of the powder can adhere to the baffle 62, and the powder continuously entering the first powder channel 11 through the feed opening 31 can flush the powder adhering to the baffle 62 at the same time of colliding with the baffle 62, so that the adhesion of the powder to the baffle 62 can be reduced. In this way, the reduction of the adhesion of the powder to the inner walls of the first powder channel 11, the inner walls of the second powder channel 12, and the baffle 62 can reduce the powder remaining in the powder outlet channel 10, improve the utilization rate of the powder, and reduce the situation that the quality of the beverage liquid is affected due to the lack of the powder.

[0074] For example, the mounting bracket 61 can be fixedly connected to the powder channel portion 33 and / or the interface portion 34 by buckling. The mounting bracket 61 can be provided with a through hole 611, the baffle 62 can pass through the through hole 611, and the baffle 62 can extend into the first powder channel 11 through the through hole 611, and the baffle 62 can be fixedly connected to the mounting bracket 61 by buckling.

The powder outlet mechanism 1022 can further include a driving assembly 70, the driving assembly 70 being at least partially arranged in the second space 26, and the driving assembly 70 can be connected to the lifting assembly 40. The driving assembly 70 can drive the lifting assembly 40 to move in the third direction.

[0076] The lifting assembly 40 can include a lifting member 43. The lifting member 43 can be in a cylindrical shape and can extend in the third direction. The lifting member 43 can be sleeved on the powder channel portion 33, the lifting member 43 can be provided with a gap 42 for avoiding the interface portion 34, the second powder channel 12 can be arranged in the lifting member 43, and the second discharge opening 41 can be arranged at the bottom of the lifting member 43. The lifting member 43 can be connected to the driving assembly 70, and the driving assembly 70 can drive the lifting member 43 to move in the third direction, so as to adjust the length of the powder outlet channel 10.

[0077] It can be understood that the driving assembly 70 can be a component that operates by means of electricity or gas to drive the lifting member 43 to move.

[0078] In some embodiments, the driving assembly 70 can include a rack 71, a gear 72, and a driving member 73.

[0079] The rack 71 can be fixedly installed on one side of the lifting member 43 facing the second space 26 in the second direction, and can extend in the third direction. The gear 72 can be at least partially received in the second space 26, and can be engaged with the rack 71. The driving member 73 can be received in the second space 26, and the body 101 of the driving member 73 can be fixedly connected with the first shell 23 and / or the second shell 24. The output end of the driving member 73 can be fixedly connected with the gear 72. The driving member 73 can drive the gear 72 to rotate, so as to move the rack 71 and the lifting member 43 in the third direction.

[0080] In the embodiments of the present application, the type of the driving member 73 is not specifically limited. For example, the driving member 73 can be, but is not limited to, a motor.

[0081] For example, a cover 27 can be formed on the first shell 23, and the cover 27 can enclose a space which can be matched to constitute the second space 26. The cover 27 can be adapted to the body 101 of the driving member 73, and the driving member 73 can be at least partially received in the space enclosed by the cover 27, so as to realize the positioning of the driving member 73 and the first shell 23.

[0082] In some cases, the rack 71 can include a plurality of teeth, the plurality of teeth can be fixedly installed on one side of the lifting member 43 facing the second space 26 in the second direction, and the plurality of teeth can be spaced apart in the third direction, so as to form the rack 71. In other cases, the rack 71 can include a connecting strip and a plurality of teeth, the connecting strip can extend in the third direction, the plurality of teeth can be spaced apart on one side of the connecting strip in the third direction, and the connecting strip can be fixedly installed on one side of the lifting member 43 facing the second space 26 in the second direction. The embodiments of the present application are not limited in this regard.

[0083] Please refer to Figure 11 In some embodiments, the beverage machine 100 can further include a processor 104. The processor 104 can be communicatively connected with the driving member 73.

[0084] The powder discharging mechanism 1022 can further include a first switch 80 and a second switch 90, which can be located outside the first shell 23 and can be spaced apart in the third direction. The first switch 80 is located below the second switch 90. The first switch 80 and the second switch 90 are both communicatively connected with the processor 104, and are communicatively connected with the driving member 73 through the processor 104.

[0085] A sliding groove 28 can be formed on the first shell 23, and the sliding groove 28 can extend in the third direction. The first switch 80 and the second switch 90 are respectively located on two sides of the sliding groove 28 in the third direction.

[0086] The lifting assembly 40 can further include a contact head 44, which can protrude from a side of the lifting piece 43 away from the powdering mechanism 1021 in the first direction. The contact head 44 can pass through the sliding groove 28 in the first direction and be in sliding connection with the sliding groove 28 in the third direction. The contact head 44 can press the first switch 80 or the second switch 90 during movement in the third direction.

[0087] When the driving piece 73 drives the lifting piece 43 to descend and extend out of the shell 20 through the discharge opening 22, the contact head 44 moves synchronously and approaches the first switch 80 until pressing the first switch 80. When the contact head 44 presses the first switch 80, the first switch 80 outputs a switch signal to the processor 104. After receiving the switch signal, the processor 104 can determine that the distance of the lifting piece 43 descending has reached a preset upper limit of distance. At this time, the processor 104 can trigger the driving piece 73 to stop working, so as to stop the lifting piece 43 from descending, reduce the extrusion between the lifting assembly 40 and the brewing device 103, and avoid the separation of the lifting assembly 40 and the powder receiving assembly 30.

[0088] When the driving piece 73 drives the lifting piece 43 to ascend and enter the first space 21 through the discharge opening 22, the contact head 44 moves synchronously and approaches the second switch 90 until pressing the second switch 90. When the contact head 44 presses the second switch 90, the second switch 90 outputs a switch signal to the processor 104. After receiving the switch signal, the processor 104 can determine that the distance of the lifting piece 43 ascending has reached a preset upper limit of distance. At this time, the processor 104 can trigger the driving piece 73 to stop working, so as to stop the lifting piece 43 from ascending and reduce the extrusion between the lifting assembly 40 and the powder receiving assembly 30.

[0089] In the embodiments of the present application, the manner of the communication connection is not specifically limited. For example, the communication connection can be a wired communication connection realized through signal lines and the like. For another example, the communication connection can be a wireless communication connection realized through 3G, 4G, 5G, Bluetooth, wireless local area network, cellular network and the like.

[0090] In the embodiments of the present application, the types of the first switch 80 and the second switch 90 are not specifically limited. For example, the first switch 80 and the second switch 90 can both be, but are not limited to, micro switches.

[0091] It can be understood that the processor 104 can also be in communication connection with the powdering mechanism 1021 and the brewing device 103, and can trigger the powdering mechanism 1021 to start and stop grinding the bean material and trigger the brewing device 103 to start and stop brewing the powder material.

[0092] In some other embodiments, the driving member 73 can be connected to the first switch 80 and the second switch 90 through a circuit structure, and the first switch 80 and the second switch 90 can be closed or disconnected after being pressed, and the current and / or voltage in the circuit structure can be changed, so that the driving member 73 is triggered to stop working through the change of the current and / or voltage.

[0093] In some other embodiments, the driving assembly 70, the first switch 80 and the second switch 90 can not be arranged in the powder outlet mechanism 1022, and the movement of the lifting assembly 40 in the third direction can be achieved by manual pushing by a person. For example, the contact head 44 can be arranged outside the machine body 101, and the person can move the lifting assembly 40 in the third direction by pushing the contact head 44.

[0094] The powder grinding device 102 and the beverage machine 100 provided by the embodiments of the present application can realize the following functions. After the powder grinding mechanism 1021 grinds the bean material to obtain the powder, the lifting assembly 40 can be lowered to drive the movable door 50 to rotate to open the discharge opening 22, and the powder grinding device 102 can extend out of the shell 20 through the discharge opening 22 and be close to the brewing device 103. Then, the powder obtained by the powder grinding mechanism 1021 can be moved out of the powder grinding mechanism 1021 through the first discharge opening 10211, and be moved out of the powder outlet mechanism 1022 through the inlet 31, the first powder channel 11, the second powder channel 12 and the second discharge opening 41, and be moved into the brewing device 103.

[0095] After the grinding of the powder is completed, and before the brewing device 103 brews the powder, the lifting assembly 40 can be raised to retract into the first space 21, and at this time, the elastic member 51 can drive the movable door 50 to rotate through the elastic force generated by the elastic deformation, so as to close the discharge opening 22. Then, the brewing device 103 can brew the received powder to obtain the beverage liquid.

[0096] When the powder needs to be transferred to the brewing device 103, the powder outlet channel 10 in the powder outlet mechanism 1022 can be lengthened through the movement of the lifting assembly 40 to cover the space originally spaced between the powder outlet mechanism 1022 and the brewing device 103, so as to shorten the distance between the second discharge opening 41 and the brewing device 103, strengthen the sealing of the moving path of the powder, and reduce the situation that part of the powder moved out of the second discharge opening 41 cannot enter the brewing device 103 due to splashing and splashes onto other components of the beverage machine 100. In this way, the length-adjustable powder outlet channel 10 can increase the cleanliness of the components in the machine body 101, and reduce the difficulty of cleaning the components by the user.

[0097] Meanwhile, the shielding assembly 60 can shield the powder moving along the first powder channel 11 in the first direction and guide the powder to move in the direction of the first powder channel 11 towards the second discharge port 41, thereby improving the flow of the powder from the powder discharge mechanism 1022 to the brewing device 103.

[0098] It is apparent that a person skilled in the art can make many modifications to the details of the application here described without departing from the scope of the application. The application is therefore not limited to the embodiments described above, which are given only by way of non-restrictive example, and the scope of protection afforded to it is defined by the claims that follow and not by the description above, which is to be considered merely illustrative.
