Rather, the use of the words "exemplary" or "for example" is intended to present related concepts in a specific way.

[0032] Please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 Fig. 1 shows a beverage machine 100 provided by an embodiment of the present application.

[0033] In an embodiment of the present application, when the beverage machine 100 is working, beverage raw materials (not shown in the figure) can be brewed to obtain beverage liquid, and the beverage liquid can flow out of the beverage machine 100 to enter a container prepared in advance by a user. The process of brewing the beverage raw materials can include a process of compacting the beverage raw materials and a process of extracting the beverage raw materials by liquid.

[0034] It can be understood that in order to improve the flavor of the beverage liquid after extraction, the beverage raw materials brewed by liquid can be in powder form, and the powder form of the beverage raw materials can be in full contact with the liquid, thereby increasing the flavor of the beverage raw materials in the beverage liquid. In an embodiment of the present application, the type of beverage raw materials is not specifically limited. For example, the beverage raw materials can be, but are not limited to, coffee powder. Exemplarily, the beverage liquid can be coffee liquid obtained by brewing coffee powder by liquid.

[0035] In an embodiment of the present application, the type of liquid used for extracting beverage raw materials is not specifically limited. For example, the liquid used for extracting beverage raw materials can be, but is not limited to, water.

[0036] It can be understood that the principle of compacting and extracting beverage raw materials to obtain beverage liquid is a general principle in the related field, which will not be repeated here.

[0037] In an embodiment, the beverage machine 100 can include a machine body 101, a brewing mechanism 102, a water injection mechanism 103, and a milk injection mechanism 104.

[0038] The machine body 101 can have an outer shell and a support structure inside the outer shell. The brewing mechanism 102 can be located inside the machine body 101 and mounted on the support structure of the machine body 101. The brewing mechanism 102 can accommodate beverage raw materials. The water injection mechanism 103 can be in communication with the brewing mechanism 102, and the water injection mechanism 103 can transmit liquid to the brewing mechanism 102, which can be applied to extraction of the beverage raw materials in the brewing mechanism 102. The milk frothing mechanism 104 can realize milk frothing by mixing air, high-temperature steam and milk, and make milk froth.

[0039] In some cases, the machine body 101 can be configured with a feeding port (not shown in the figure), and the user can pour the powdered beverage raw materials into the beverage machine 100 through the feeding port, so that the beverage raw materials enter the brewing mechanism 102. In other cases, the beverage machine 100 can also include a grinding mechanism (not shown in the figure), which can receive bean materials and grind the bean materials to obtain powdered beverage raw materials; the grinding mechanism can transmit the ground beverage raw materials to the brewing mechanism 102. The embodiments of the present application are not limited in this regard.

[0040] It can be understood that the water injection mechanism 103 is arranged inside or outside the machine body 101, and the embodiments of the present application are not limited in this regard. At the same time, the water injection mechanism 103 can be in communication with the brewing mechanism 102 through a pipeline, and the water injection mechanism 103 can have a water pump, so that the water pump can inject the liquid stored or accessed by the water injection mechanism 103 into the brewing mechanism 102 through the pipeline.

[0041] It can be understood that the milk frothing mechanism 104 can access milk, air and high-temperature steam, and can perform a milk frothing action to mix the milk, air and high-temperature steam to obtain milk froth and output the milk froth. At least part of the structure of the milk frothing mechanism 104 can be located inside the machine body 101 and fixedly connected with the support structure of the machine body 101. The milk froth generated by the milk frothing mechanism 104 can be discharged from the beverage machine 100 through the same or different outlet as the beverage liquid generated by the brewing mechanism 102, and the embodiments of the present application are not limited in this regard.

[0042] At the same time, the milk frothing mechanism 104 can be in communication with the brewing mechanism 102 through a pipeline, and the steam, gas and / or liquid in the milk frothing mechanism 104 can be discharged through the brewing mechanism 102 after the milk frothing mechanism 104 performs the milk frothing operation to complete the preparation of the milk froth.

[0043] Please refer to Figure 3 and Figure 4 In some embodiments, the brewing mechanism 102 can include a brewing device 10, a brewing structure 20 and a liquid inlet assembly 30.

[0044] The brewing device 10 and the brewing structure 20 can be arranged in a preset direction. The brewing device 10 can be internally configured with a brewing cavity 11, which can penetrate the top of the brewing device 10. The brewing cavity 11 can receive and accommodate beverage raw materials. The brewing structure 20 can pass through the brewing cavity 11 at the top of the brewing device 10. The brewing structure 20 can be in contact with the beverage raw materials in the brewing cavity 11 and perform compaction processing to reduce the voids in the powdered beverage raw materials. The liquid inlet assembly 30 can be fixedly connected with the brewing structure 20 and can be in communication with the water injection mechanism 103 and the brewing structure 20. The liquid inlet assembly 30 can introduce liquid to the brewing structure 20, and the liquid can extract the compacted beverage raw materials in the brewing cavity 11 to obtain beverage liquid.

[0045] The brewing device 10 can also be configured with a liquid outlet channel (not shown in the figure), which is in communication with the brewing cavity 11, and the beverage liquid can flow out of the brewing device 10 through the liquid outlet channel. The machine body 101 can be provided with a liquid outlet end 1011, and after the beverage liquid flows out of the brewing device 10 through the liquid outlet channel, it can flow out of the machine body 101 through the liquid outlet end 1011 and into a container prepared by the user.

[0046] It can be understood that the beverage raw materials can be compacted by the brewing structure 20 and then extracted by the liquid introduced by the liquid inlet assembly 30 to obtain beverage liquid, thereby reducing the situation that the liquid scatters the beverage raw materials when brewing the beverage raw materials and affects the quality of the beverage liquid.

[0047] It can be understood that the liquid inlet assembly 30 can also be connected and communicated with the milk frothing mechanism 104, thereby realizing the communication between the milk frothing mechanism 104 and the brewing mechanism 102.

[0048] In some embodiments, the beverage machine 100 can further include a switching valve 105, which can have two input ends and one output end. Only one input end of the switching valve 105 can be in communication with the output end, and the switching valve 105 can block the input end originally in communication with the output end and make the other input end in communication with the output end when the working state of the switching valve 105 changes.

[0049] The water injection mechanism 103 can be connected and communicated with one output end of the switching valve 105 through a pipeline, and the milk frothing mechanism 104 can be connected and communicated with the other output end of the switching valve 105 through a pipeline. The liquid inlet assembly 30 can be connected and communicated with the input end of the switching valve 105.

[0050] The switching valve 105 can maintain the communication between the water injection mechanism 103 and the liquid inlet assembly 30. When the beverage machine 100 makes beverage liquid, the water injection mechanism 103 can transmit liquid to the brewing structure 20 to extract the beverage raw materials.

[0051] After the milk frothing mechanism 104 completes the milk frothing operation, the switching valve 105 can switch the working state to make the milk frothing mechanism 104 communicate with the liquid inlet assembly 30. At this time, the milk frothing mechanism 104 that completes the milk froth preparation realizes pressure relief through the communication with the liquid inlet assembly 30, and the gas, liquid or steam in the milk frothing mechanism 104 can flow to the brewing mechanism 102 through the liquid inlet assembly 30 and be discharged to the outside through the brewing mechanism 102.

[0052] In the embodiments of the present application, the type of the switching valve 105 is not specifically limited. For example, the switching valve 105 can be, but is not limited to, a solenoid valve.

[0053] It can be understood that the switching valve 105 can also have a closed state. When the switching valve 105 is closed, the two input ends of the switching valve 105 are both cut off from the output end. At this time, the liquid inlet assembly 30 can be cut off from both the water injection mechanism 103 and the milk frothing mechanism 104.

[0054] In the embodiments of the present application, the length direction, the width direction and the height direction of the brewing mechanism 102 can be defined as the first direction, the second direction and the vertical direction, respectively. For example, the first direction can be the X direction and the opposite direction thereof as shown in Figure 3 and Figure 4 The second direction can be the Y direction and the opposite direction thereof as shown in Figure 3 and Figure 4 The vertical direction can be the Z direction and the opposite direction thereof as shown in Figure 3 and Figure 4 Among them, the brewing mechanism 102 and its components can have a top and a bottom arranged oppositely in the vertical direction.

[0055] It can be understood that the brewing structure 20 and the brewer 10 can move relatively in the vertical direction, so that the brewing structure 20 enters or moves out of the brewing chamber 11.

[0056] In some cases, when the brewing structure 20 and the brewer 10 move relatively in the vertical direction, one of the brewing structure 20 and the brewer 10 can be relatively fixed to the machine body 101, and the other can move in the vertical direction within the machine body 101. In other cases, when the brewing structure 20 and the brewer 10 move relatively in the vertical direction, both the brewing structure 20 and the brewer 10 move. The embodiments of the present application do not limit this.

[0057] It can be understood that the beverage machine 100 can also include a driving mechanism. The brewing structure 20 and / or the brewer 10 can be connected to the driving mechanism and move within the machine body 101 under the driving of the driving mechanism. The principle of the driving mechanism driving the brewing structure 20 and / or the brewer 10 to move can be the general principle in the related field, which will not be described here.

[0058] In the embodiments of the present application, the type of the driving mechanism is not specifically limited. For example, the driving mechanism can be, but is not limited to, a linear motor or a pneumatic cylinder.

[0059] Please refer to Figure 5 In some embodiments, the brewing structure 20 can include a mounting member 21, a brewing assembly 22, and a pressing elastic member 23.

[0060] The brewing assembly 22 can be sleeved on the mounting member 21 and movably connected to the mounting member 21 in the vertical direction. When the brewing structure 20 and the brewing device 10 are relatively moved in the vertical direction so that the brewing structure 20 enters the brewing chamber 11, the brewing assembly 22 and the mounting member 21 are synchronously moved in the vertical direction. The brewing assembly 22 can enter the brewing chamber 11. The bottom of the brewing assembly 22 can be in contact with the beverage raw material in the brewing chamber 11 and compact the beverage raw material. The bottom of the brewing assembly 22 can be configured with a liquid outlet hole 2221 for liquid flow. The liquid inlet assembly 30 can be in communication with the liquid outlet hole 2221. After the brewing assembly 22 completes the compaction of the beverage raw material, the liquid inlet assembly 30 can access the liquid and inject the liquid into the beverage raw material through the liquid outlet hole 2221, thereby completing the extraction of the beverage raw material.

[0061] The bottom of the mounting member 21 can be configured with a positioning groove 211. The brewing assembly 22 can be fixedly connected with a positioning column 2211 corresponding to the positioning groove 211. The positioning groove 211 can extend in the vertical direction, and the positioning column 2211 can extend in the vertical direction. The positioning column 2211 can at least partially enter the positioning groove 211. The positioning column 2211 can be synchronously moved with the brewing assembly 22, so as to move in the vertical direction in the positioning groove 211 when the mounting member 21 and the brewing assembly 22 are relatively moved.

[0062] The pressing elastic member 23 can be supported between the mounting member 21 and the brewing assembly 22. The pressing elastic member 23 can be at least partially accommodated in the positioning groove 211 and can be connected between the inner wall of the positioning groove 211 and the positioning column 2211. The side wall of the positioning groove 211 and the positioning column 2211 can block the pressing elastic member 23, thereby limiting the swinging of the pressing elastic member 23 in a direction perpendicular to the vertical direction. In this way, the positioning groove 211 and the positioning column 2211 can cooperate to limit the swinging of the pressing elastic member 23.

[0063] It can be understood that the pressing elastic member 23 can have a pre-tightening force. When the bottom of the brewing assembly 22 is not in abutment with the beverage raw material, the pressing elastic member 23 can support the mounting member 21 and the brewing assembly 22 by the elastic force generated by its compression, so that the bottom of the mounting member 21 is arranged in a spaced manner in the vertical direction from the brewing assembly 22.

[0064] When the brewing structure 20 moves into the brewing cavity 11 and the bottom of the brewing assembly 22 abuts against the beverage raw material in the brewing cavity 11, the mounting member 21 can continue to move in the vertical direction to extend into the brewing cavity 11, at this time the brewing assembly 22 can maintain abutting against the beverage raw material and can move relative to the mounting member 21, so that the distance between the bottom of the mounting member 21 and the brewing assembly 22 in the vertical direction is shortened, and the compression elastic member 23 is compressed; under the pushing of the mounting member 21 and the elastic driving of the compression elastic member 23, the brewing assembly 22 continuously presses on the beverage raw material, so as to realize the compaction treatment of the beverage raw material.

[0065] When the beverage raw material in the brewing cavity 11 decreases, the deformation degree of the compression elastic member 23 after the brewing assembly 22 presses on the beverage raw material can relatively decrease, and the relative moving distance of the brewing assembly 22 and the mounting member 21 decreases; when the beverage raw material in the brewing cavity 11 increases and the thickness of the beverage raw material increases, the deformation degree of the compression elastic member 23 after the brewing assembly 22 presses on the beverage raw material can relatively increase, and the relative moving distance of the brewing assembly 102 and the mounting member 21 increases; no matter the volume of the beverage raw material in the brewing cavity 11, the brewing assembly 22 can realize the compaction treatment of the beverage raw material through the movement of the mounting member 21 and the support of the compression elastic member 23. In this way, the insufficient contact between the brewing structure 20 and the beverage raw material due to the insufficient volume of the beverage raw material when the beverage raw material is compacted can be reduced, and the effect of the compaction treatment of the beverage raw material can be improved.

[0066] It can be understood that when the liquid is injected into the beverage raw material, the flow of the liquid through the powdered beverage raw material can cause the beverage raw material to be locally loose, and the local looseness of the beverage raw material can cause the liquid to be unable to flow through part of the powder, thereby affecting the quality of the beverage liquid after brewing. In the brewing mechanism 102 of the present application, the brewing assembly 22 can maintain the compaction treatment of the beverage raw material under the elastic driving of the compression elastic member 23, and the continuous compaction treatment of the brewing assembly 22 during the process of brewing the beverage raw material can reduce the looseness of the powdered beverage raw material, and can timely compact the beverage raw material when the beverage raw material is loose, so as to reduce the influence of the local looseness of the beverage raw material on the quality of the beverage liquid, and improve the quality of the beverage liquid produced by the beverage machine 100.

[0067] It can be understood that after the brewing of the beverage raw material is completed, the brewer 10 and the brewing structure 20 can move away from each other to perform a retreat action, and the brewing structure 20 can move out of the brewing cavity 11 after the retreat action is completed, and the brewing assembly 22 and the mounting member 21 can move away from each other under the elastic driving of the compression elastic member during the retreat process, until the brewing assembly 22 is separated from the brewed beverage raw material, the brewing assembly 22 can be relatively fixed with the mounting member 21 and retreat synchronously.

[0068] In the embodiments of this application, the fixing method for fixed connection and fixed installation is not specifically limited. For example, the fixing method may include, but is not limited to, bolt fixing, screw fixing, welding fixing, integral molding fixing, and interference fixing.

[0069] In the embodiments of this application, the type of the pressure elastic element 23 is not specifically limited. For example, the pressure elastic element 23 can be, but is not limited to, a spring.

[0070] It is understood that the number of positioning grooves 211, positioning posts 2211, and pressure elastic elements 23 can be equal. In the embodiments of this application, the number of pressure elastic elements 23, positioning grooves 211, and positioning posts 2211 is not specifically limited. For example, as... Figure 4 and Figure 5 As shown, there can be two positioning slots 211, which can be spaced apart in the first direction; there can be two positioning posts 2211, which can be spaced apart in a direction perpendicular to the vertical direction and correspond one-to-one with the two positioning slots 211. When the brewing component 22 and the mounting component 21 move relative to each other, each positioning post 2211 can extend into or out of the corresponding positioning slot 211 in the vertical direction; there can be two pressing elastic elements 23, which can be springs. The two pressing elastic elements 23 can be respectively sleeved on the corresponding positioning posts 2211, and at least their tops can be housed in the corresponding positioning slots 211. The two ends of each pressing elastic element 23 in the vertical direction can abut or be fixedly connected to the top wall of the positioning slot 211 and the brewing component 22.

[0071] It is understood that there can be multiple liquid outlet holes 2221, and these multiple liquid outlet holes 2221 can be spaced apart in the first direction and / or the second direction.

[0072] It is understandable that after the beverage liquid is brewed and the brewing structure 20 is removed from the brewing chamber 11, the beverage machine 100 can automatically clean and replenish the beverage ingredients in the brewing chamber 11. The method by which the beverage machine 100 cleans and replenishes the beverage ingredients can be a common method in the relevant field, and will not be described in detail here.

[0073] In some embodiments, the middle portion of the mounting member 21 may extend vertically to form the bottom of the mounting member 21. A first receiving cavity 212 may be constructed in the mounting member 21, extending through the top of the mounting member 21. The cross-section of the middle portion of the mounting member 21 may be circular, and the cross-section of the first receiving cavity 212 may also be circular. Positioning grooves 211 may be spaced apart from the first receiving cavity 212.

[0074] The brewing assembly 22 can include a brewing plug 221 and a powder pressing member 222. The brewing plug 221 can be in a sleeve shape, and a second receiving cavity 2212 can be configured on the brewing plug 221, penetrating the top of the brewing plug 221 in the vertical direction, and a positioning column 2211 can be fixedly connected to the bottom wall of the second receiving cavity 2212. The cross section of the brewing plug 221 can be circular, and the cross section of the second receiving cavity 2212 can be circular. The middle part of the mounting member 21 can be received in the second receiving cavity 2212, so that the brewing plug 221 can be sleeved on the mounting member 21. The mounting member 21 is movably connected to the second receiving cavity 2212 in the vertical direction.

[0075] The bottom of the brewing plug 221 can be configured with a first mounting groove 2213. The powder pressing member 222 can be received in the first mounting groove 2213 and fixedly connected with the brewing plug 221. There is a gap between the top of the powder pressing member 222 and the top wall of the first mounting groove 2213, and the bottom of the powder pressing member 222 can be flush with the bottom of the brewing plug 221. The powder pressing member 222 can be pressed on the beverage raw material to perform compaction treatment on the beverage raw material. A plurality of liquid outlet holes 2221 can be configured in the powder pressing member 222 and penetrate the powder pressing member 222 in the vertical direction. The plurality of liquid outlet holes 2221 are all in communication with the first mounting groove 2213. The liquid inlet assembly 30 can be in communication with the first mounting groove 2213, and after the liquid inlet assembly 30 is connected to the liquid, the liquid can enter the gap between the top wall of the first mounting groove 2213 and the top of the powder pressing member 222, and then flow out through the plurality of liquid outlet holes 2221 and be injected into the beverage raw material compacted by the powder pressing member 222.

[0076] It can be understood that the cross section of the brewing cavity 11 can be circular, and the circular sleeve-shaped brewing plug 221 can move in the vertical direction in the brewing cavity 11.

[0077] A sealing ring can be sleeved on the brewing plug 221. When the brewing plug 221 enters the brewing cavity 11 to make the powder pressing member 222 perform compaction treatment on the beverage raw material, the sealing ring can abut against the inner wall of the brewing cavity 11, so as to block the brewing cavity 11 into two parts arranged in the vertical direction. The sealing ring can block the liquid injected into the brewing cavity 11 to brew the beverage raw material, so as to reduce the occurrence of liquid leakage from the brewing cavity 11, reduce the occurrence of insufficient beverage liquid caused by liquid leakage after brewing, and improve the quality of the beverage liquid and the user experience.

[0078] In some embodiments, the brewing mechanism 102 can further include a first flow channel assembly 40, a second flow channel assembly 50, and a third flow channel assembly 60.

[0079] The first flow channel assembly 40 can be in communication with the liquid inlet assembly 30 and the liquid outlet hole 2221, respectively. After the beverage raw material in the brewing chamber 11 is compacted by the brewing assembly 22, the water injection mechanism 103 can transmit liquid to the first flow channel assembly 40 through the liquid inlet assembly 30, and the first flow channel assembly 40 can transmit the liquid to the brewing chamber 11 through the liquid outlet hole 2221 to extract the beverage raw material.

[0080] One end of the second flow channel assembly 50 can be in communication with the brewing chamber 11 through the liquid outlet hole 2221, and the other end can be switched to be in communication with the external space other than the brewing mechanism 102. When the brewing plug 221 moves in the brewing chamber 11, the second flow channel assembly 50 can be in communication with the external space, so that the gas in the brewing chamber 11 can be discharged to the external space. When the liquid inlet assembly 30 transmits liquid to the brewing chamber 11, i.e., the liquid extracts the beverage raw material in the brewing chamber 11, the second flow channel assembly 50 can be cut off from the external space.

[0081] The third flow channel assembly 60 can be in communication with the liquid inlet assembly 30 and the external space. When the liquid inlet assembly 30 is in communication with the milk frothing mechanism 104, the gas, steam and / or liquid in the milk frothing mechanism 104 can be sequentially discharged to the external space through the liquid inlet assembly 30 and the third flow channel assembly 60 after the milk frothing mechanism 104 performs the milk frothing operation.

[0082] It can be understood that the external space can refer to a space outside the brewing mechanism 102. The second flow channel assembly 50 and the third flow channel assembly 60 can also be in communication with the external space through a pipe or other structure extending to the outside of the machine body 101. The gas discharged from the brewing mechanism 102 through the second flow channel assembly 50 and the gas, liquid and / or steam discharged from the brewing mechanism 102 through the third flow channel assembly 60 can be discharged from the brewing mechanism 102 and the machine body 101 through the pipe.

[0083] It can be understood that the first flow channel assembly 40 and the liquid inlet assembly 30 cooperate to provide liquid to the brewing chamber 11 when the brewing mechanism 102 makes beverage liquid. The second flow channel assembly 50 can provide a discharge channel for the gas in the brewing chamber 11 when the brewing plug 221 moves in the brewing chamber 11, thereby reducing the occurrence of the situation that the gas in the brewing chamber 11 hinders the movement of the brewing plug 221. The third flow channel assembly 60 and the liquid inlet assembly 30 cooperate to provide a discharge channel for the gas, steam and / or liquid in the milk frothing mechanism 104 after the milk frothing mechanism 104 completes the preparation of milk froth.

[0084] When the brewing assembly 22 moves in the brewing chamber 11, the sealing ring of the brewing plug 221 can divide the brewing chamber 11 into two parts in the vertical direction, and the part below the sealing ring is in a sealed state. At this time, the rising of the brewing assembly 22 in the brewing chamber 11 will reduce the air pressure of the space below the sealing ring, so that the air pressure above the sealing ring is greater than that below the sealing ring, thereby hindering the rising of the brewing assembly 22. The descending of the brewing assembly 22 in the brewing chamber 11 will increase the air pressure of the space below the sealing ring, so that the air pressure below the sealing ring is greater than that above the sealing ring, and the air below the sealing ring is compressed and hinders the descending of the brewing assembly 22.

[0085] The second flow channel assembly 50 is arranged to enable the space below the sealing ring in the brewing chamber 11 to communicate with the second flow channel assembly 50 through the liquid outlet hole 2221 and the first mounting slot 2213, and when the brewing assembly 22 descends in the brewing chamber 11, the air in the brewing chamber 11 can be discharged to the external space through the liquid outlet hole 2221, the first mounting slot 2213 and the second flow channel assembly 50, thereby reducing the hindrance to the compaction of the beverage raw materials by the brewing assembly 22 and improving the smoothness of the compaction of the beverage raw materials by the brewing assembly 22. At the same time, when the brewing assembly 22 rises in the brewing chamber 11, the air in the external space can enter the brewing chamber 11 through the second flow channel assembly 50, the first mounting slot 2213 and the liquid outlet hole 2221, thereby reducing the hindrance to the movement of the brewing assembly 22 out of the brewing chamber 11 and improving the smoothness of the movement of the brewing assembly 22 out of the brewing chamber 11.

[0086] Therefore, the brewing mechanism 102 provided by the present application can improve the smoothness of the movement of the brewing assembly 22 in the brewing chamber 11, thereby improving the smoothness of the operation of the brewing mechanism 102 and the beverage machine 100. At the same time, the hindrance to the movement of the brewing assembly 22 in the brewing chamber 11 is reduced, thereby reducing the load of the driving mechanism, reducing the failure rate of the driving mechanism, and increasing the service life of the driving mechanism and the beverage machine 100.

[0087] It can be understood that the first flow channel assembly 40 and the second flow channel assembly 50 can cooperate to form a system that can allow liquid to enter the brewing mechanism 102 and block air outside the brewing mechanism 102, and can provide a discharge path for the air, steam and / or liquid in the milk frothing mechanism 104, thereby achieving pressure relief for the milk frothing mechanism 104 without adjusting the structure of the milk frothing mechanism 104, thereby reducing the load of the milk frothing mechanism 104, reducing the failure rate of the milk frothing mechanism 104, and increasing the service life of the milk frothing mechanism 104 and the beverage machine 100.

[0088] In some embodiments, the brewing mechanism 102 can further comprise a connecting assembly 70. The connecting assembly 70 can be fixedly connected to the mounting member 21 and can be received in the first receiving cavity 212. A top portion of the connecting assembly 70 can be provided with a connecting passage 711. The liquid inlet assembly 30 can be inserted into the connecting passage 711 and communicate with the connecting passage 711. The liquid inlet assembly 30 can be fixedly connected to the connecting assembly 70.

[0089] The first flow channel assembly 40 can comprise a liquid inlet pipe 41 fixedly connected to the brewing plug 221. The liquid inlet pipe 41 can be vertically arranged through the bottom of the mounting member 21 so as to enter the first receiving cavity 212 from the second receiving cavity 2212. A bottom portion of the liquid inlet pipe 41 can communicate with the first mounting groove 2213. The third flow channel assembly 60 can comprise a liquid inlet groove 61. The liquid inlet groove 61 can be arranged at a bottom portion of the connecting assembly 70 and can be correspondingly arranged with the connecting passage 711. The liquid inlet groove 61 can communicate with the liquid inlet assembly 30 through the connecting passage 711. At least a top portion of the liquid inlet pipe 41 can be received in the liquid inlet groove 61 and can communicate with the liquid inlet groove 61.

[0090] It can be understood that when the brewing assembly 22 and the mounting member 21 move relative to each other, the liquid inlet pipe 41 can synchronously move in the liquid inlet groove 61 and maintain communication with the liquid inlet groove 61, thereby maintaining communication with the liquid inlet assembly 30. After the powder compacting member 222 completes compaction of the beverage raw material, the brewing assembly 22 and the mounting member 21 can stop moving relative to each other, and the water injection mechanism 103 can output liquid to the liquid inlet assembly 30. The liquid can flow into the liquid inlet pipe 41 through the liquid inlet groove 61 and be injected into the beverage raw material in the brewing chamber 11 through the first mounting groove 2213 and the liquid outlet hole 2221, thereby completing brewing of the beverage liquid.

[0091] It can be understood that the liquid inlet pipe 41 can be arranged in a spaced-apart manner with the positioning column 2211.

[0092] In some embodiments, the liquid inlet pipe 41 can be provided with a liquid inlet passage 411, a liquid inlet hole 412 and a liquid inlet cavity 413 arranged in a vertical direction. The liquid inlet passage 411 can pass through a top portion of the liquid inlet pipe 41 and communicate with the liquid inlet groove 61. The liquid inlet cavity 413 can pass through a bottom portion of the liquid inlet pipe 41 and communicate with the first mounting groove 2213. The liquid inlet hole 412 can communicate between the liquid inlet passage 411 and the liquid inlet cavity 413, and a cross-sectional area of the liquid inlet hole 412 can be smaller than a cross-sectional area of the liquid inlet cavity 413.

[0093] The brewing mechanism 102 can further comprise a valve plug 80 and a valve elastic member 90. A top portion of the valve plug 80 can enter or move out of the liquid inlet hole 412 in a vertical direction. When the valve plug 80 enters the liquid inlet hole 412, the valve plug 80 can abut against an inner wall of the liquid inlet hole 412 and / or a top wall of the liquid inlet cavity 413, thereby closing the liquid inlet hole 412.

[0094] The valve elastic member 90 can be located in the liquid inlet cavity 413 and can extend into the first installation groove 2213. The valve elastic member 90 can be supported and pre-pressed between the bottom of the valve plug 80 and the powder pressing member 222. The elastic force generated by the compression of the valve elastic member 90 can drive the valve plug 80 away from the powder pressing member 222 to close the liquid inlet hole 412.

[0095] In the embodiments of the present application, the type of the valve elastic member 90 is not specifically limited. For example, the valve elastic member 90 can be, but is not limited to, a spring, a rubber member, or a silica gel member.

[0096] It can be understood that when the liquid inlet assembly 30 is not connected to the liquid, the valve plug 80 can be maintained to close the liquid inlet hole 412 by the elastic force of the valve elastic member 90, thereby reducing the occurrence of the liquid in the liquid inlet cavity 413 flowing back to the liquid inlet groove 61 and the liquid inlet assembly 30, and reducing the occurrence of the liquid for extracting the beverage raw material being insufficient to affect the quality of the beverage liquid.

[0097] When the water injection mechanism 103 inputs the liquid to the liquid inlet assembly 30, the flowing liquid can exert pressure on the valve plug 80, thereby driving the valve plug 80 to approach the powder pressing member 222 to open the liquid inlet hole 412. After the liquid inlet hole 412 is opened, the liquid can flow into the liquid inlet cavity 413 after flowing through the liquid inlet assembly 30, the liquid inlet groove 61, the liquid inlet channel 411, and the liquid inlet hole 412, and be injected into the beverage raw material through the liquid outlet hole 2221; at this time, the valve elastic member 90 is further compressed. Until the liquid inlet assembly 30 stops inputting the liquid, the valve plug 80 can close the liquid inlet hole 412 under the driving of the valve elastic member 90 to block the backflow of the liquid.

[0098] It can be understood that under the support of the valve elastic member 90, the liquid for extracting the beverage raw material can push open the valve plug 80 to be injected into the beverage raw material, and the gas, liquid, and / or steam flowing through the liquid inlet assembly 30 in the milk frothing mechanism 104 cannot push open the valve plug 80 because the pressure exerted on the valve plug 80 is less than the elastic force exerted on the valve plug 80 by the valve elastic member 90. In this way, the occurrence of the gas, liquid, and / or steam in the milk frothing mechanism 104 entering the brewing cavity 11 can be reduced, thereby reducing the dirt in the brewing cavity 11 and improving the quality of the beverage liquid.

[0099] Please refer to Figure 6 and Figure 7 In some embodiments, the second flow channel assembly 50 can include an exhaust pipe 51, a first sealing member 52, an exhaust groove 53, and a first air channel 54.

[0100] The exhaust pipe 51 can be fixedly connected with the brewing plug 221. The exhaust pipe 51 can be arranged in the vertical direction through the bottom of the mounting member 21, so as to enter the first receiving cavity 212 from the second receiving cavity 2212. The bottom of the exhaust pipe 51 can be in communication with the first mounting groove 2213. The first sealing member 52 can be arranged on the outer periphery of the exhaust pipe 51.

[0101] Please refer to Figure 8 The connecting assembly 70 can include a connecting seat 71 and an exhaust member 72. The connecting channel 711 can be arranged on the top of the connecting seat 71. The liquid inlet groove 61 can be arranged on the bottom of the connecting seat 71 and in communication with the connecting channel 711. The exhaust groove 53 can be arranged on the bottom of the connecting seat 71 and spaced apart from the liquid inlet groove 61. The top of the exhaust pipe 51 can be received in the exhaust groove 53 and can move in the vertical direction in the exhaust groove 53. The first sealing member 52 can be located in the exhaust groove 53. The inner wall of the exhaust groove 53 and / or the outer periphery of the exhaust pipe 51 are narrowed in the direction away from the brewing device 10, i.e. the cross-sectional area of the top of the inner wall of the exhaust groove 53 is smaller than the cross-sectional area of the bottom of the inner wall of the exhaust groove 53, and / or the cross-sectional area of the top of the outer periphery of the exhaust pipe 51 is smaller than the cross-sectional area of the bottom of the outer periphery of the exhaust pipe 51. In this way, as the distance of the exhaust pipe 51 rising in the exhaust groove 53 changes, i.e. the depth of the exhaust pipe 51 extending into the exhaust groove 53 changes, the distance between the first sealing member 52 and the inner wall of the exhaust groove 53 can change synchronously; when the depth of the exhaust pipe 51 extending into the exhaust groove 53 increases, the distance between the outer periphery of the exhaust pipe 51 and the inner wall of the exhaust groove 53 decreases, the distance between the first sealing member 52 and the inner wall of the exhaust groove 53 decreases and finally abuts against the inner wall of the exhaust groove 53; when the depth of the exhaust pipe 51 extending into the exhaust groove 53 decreases, the distance between the outer periphery of the exhaust pipe 51 and the inner wall of the exhaust groove 53 increases, the distance between the first sealing member 52 and the inner wall of the exhaust groove 53 increases.

[0102] One side of the connecting seat 71 in the first direction can be arranged with a connecting groove 712, and the connecting seat 71 is arranged with a first through hole 713. The first through hole 713 is located between the connecting groove 712 and the exhaust groove 53 and is in communication with the connecting groove 712 and the exhaust groove 53. The exhaust member 72 can be inserted into the connecting groove 712 and is in sealing connection with the connecting groove 712. The first air channel 54 can be arranged in the exhaust member 72. One end of the first air channel 54 can be in communication with the exhaust groove 53 through the first through hole 713, and the other end can penetrate the top of the exhaust member 72, so as to realize communication with the external space.

[0103] The first seal 52 can have an open position to open the first air passage 54 and a closed position to close the first air passage 54. When the first seal 52 is in the open position, the first air passage 54 remains in communication with the external space and the exhaust pipe 51, so that the second flow passage assembly 50 is switched to be in communication with the external space. When the first seal 52 is in the closed position, the first air passage 54 remains in communication with the external space and is blocked from the exhaust pipe 51, so that the second flow passage assembly 50 is switched to be blocked from the external space.

[0104] During the process of the brewing assembly 22 extending into the brewing cavity 11, the exhaust pipe 51 and the first seal 52 are synchronously lifted in the exhaust groove 53, and there is a gap between the first seal 52 and the inner wall of the exhaust groove 53. At this time, the first seal 52 is in the open position to open the first air passage 54. After the powder pressing member 222 abuts against the beverage raw material in the brewing cavity 11, the mounting member 21 can continue to approach the beverage raw material, and the mounting member 21 and the brewing assembly 22 approach each other. The first seal 52 can be synchronously moved to abut against the inner wall of the first exhaust groove 53 to close the first exhaust groove 53, so as to block the first air passage 54 from the exhaust pipe 51. At this time, the first seal 52 is in the closed position to close the first air passage 54.

[0105] In the embodiments of the present application, the number of the first seal 52 is not specifically limited. For example, the number of the first seal 52 can be multiple, and the multiple first seals 52 can be arranged in the vertical direction. When the first seal 52 is in the closed position, part of the first seal 52 can be located above the first through hole 713 and abut against the inner wall of the exhaust groove 53, and part of the first seal 52 can be located below the first through hole 713 and abut against the inner wall of the exhaust groove 53. In this way, the first seal 52 located on both sides of the first through hole 713 can block the space above and below the first through hole 713, and block the communication between the first air passage 54 and the exhaust pipe 51 from both sides in the vertical direction.

[0106] It can be understood that the top and bottom of the exhaust pipe 51 are provided with openings. The opening at the top realizes the communication between the exhaust pipe 51 and the exhaust groove 53, and the opening at the bottom realizes the communication between the exhaust pipe 51 and the first mounting groove 2213 and the liquid outlet hole 2221. When the multiple first seals 52 move to the closed position, at least one first seal 52 is located above the first through hole 713. The first seal 52 can block the space above the exhaust groove 53 and the first through hole 713, so as to block the opening at the top of the exhaust pipe 51 and the first through hole 713, and block the first air passage 54 and the exhaust pipe 51.

[0107] At the same time, at least one first seal 52 is located below the first through hole 713. The first seal 52 can block the space below the exhaust groove 53 and the first through hole 713.

[0108] It can be understood that the first seal 52 can be annular. When the number of the first seal 52 is plural, the plural first seals 52 arranged in the vertical direction can have different diameters at different heights.

[0109] In the embodiments of the present application, the material of the first seal 52 is not specifically limited. For example, the material of the first seal 52 can be, but is not limited to, rubber or silicone.

[0110] It can be understood that after the powder compacting member 222 compacts the beverage raw material, the liquid inlet assembly 30 can inject liquid into the beverage raw material through the liquid inlet pipe 41 and the liquid outlet hole 2221. At this time, the second flow channel assembly 50 is isolated from the external space, which can reduce the probability of liquid being discharged from the brewing chamber 11 through the exhaust pipe 51, the exhaust groove 53 and the first air channel 54, thereby reducing the probability of affecting the quality of the beverage liquid due to insufficient liquid extracted from the beverage raw material.

[0111] It can be understood that the first air channel 54 can include a first part extending in the first direction, and a second part extending in the vertical direction and communicating with the first part. At the same time, the exhaust member 72 can include a first part extending in the first direction, and a second part extending in the vertical direction and fixed with the first part. The first part of the first air channel 54 can be configured in the first part of the exhaust member 72, and can penetrate the exhaust member 72 in the first direction towards one side of the first through hole 713, so as to communicate with the exhaust groove 53 through the first through hole 713. The second part of the first air channel 54 can be configured in the second part of the exhaust member 72, and can penetrate the top of the second part of the exhaust member 72, so as to communicate with the external space.

[0112] Please refer to Figure 9 and Figure 10 In some embodiments, the first flow channel assembly 40 can further include a second seal 42, which can be sleeved on the outer periphery of the liquid inlet pipe 41 and can be accommodated in the liquid inlet groove 61.

[0113] The third flow channel assembly 60 can further include a second air channel 62. The second air channel 62 can be configured in the connecting seat 71. The connecting seat 71 further has a second through hole 714. The second air channel 62 and the second through hole 714 are both located on one side of the liquid inlet groove 61 in the second direction, and the second through hole 714 communicates between the second air channel 62 and the liquid inlet groove 61.

[0114] The inner wall of the liquid inlet groove 61 and / or the outer periphery of the liquid inlet pipe 41 narrows in the direction away from the brewing device 10, that is, the top cross-sectional area of the inner wall of the liquid inlet groove 61 is smaller than the cross-sectional area of the bottom of the inner wall of the liquid inlet groove 61, and / or the cross-sectional area of the top of the outer periphery of the liquid inlet pipe 41 is smaller than the cross-sectional area of the bottom of the outer periphery of the liquid inlet pipe 41. In this way, as the distance of the liquid inlet pipe 41 rising in the liquid inlet groove 61 changes, that is, the depth of the liquid inlet pipe 41 extending into the liquid inlet groove 61 changes, the distance between the second sealing member 42 and the inner wall of the liquid inlet groove 61 can change synchronously; when the depth of the liquid inlet pipe 41 extending into the liquid inlet groove 61 increases, the distance between the outer periphery of the liquid inlet pipe 41 and the inner wall of the liquid inlet groove 61 decreases, and the distance between the second sealing member 42 and the inner wall of the liquid inlet groove 61 decreases and eventually abuts against the inner wall of the liquid inlet groove 61; when the depth of the liquid inlet pipe 41 extending into the liquid inlet groove 61 decreases, the distance between the outer periphery of the liquid inlet pipe 41 and the inner wall of the liquid inlet groove 61 increases, and the distance between the second sealing member 42 and the inner wall of the liquid inlet groove 61 increases.

[0115] The second sealing member 42 can have an open position to open the second air passage 62 and a closed position to close the second air passage 62. When the second sealing member 42 is in the open position, the second air passage 62 remains in communication with the external space and the liquid inlet pipe 41, so that the second flow passage assembly 50 is switched to be in communication with the outside; when the second sealing member 42 is in the closed position, the second air passage 62 remains in communication with the external space, but is blocked from the liquid inlet pipe 41, so that the second flow passage assembly 50 is switched to be blocked from the outside.

[0116] During the process of the brewing device 10 and the brewing structure 20 approaching each other, the second sealing member 42 can be spaced apart from the inner wall of the liquid inlet groove 61; when the powder pressing member 222 abuts against the beverage raw material, the mounting member 21 and the brewing assembly 22 approach each other, the second sealing member 42 and the liquid inlet pipe 41 rise synchronously in the liquid inlet groove 61; until the powder pressing member 222 compacts the beverage raw material in the brewing chamber 11, the brewing assembly 22 and the mounting member 21 stop approaching each other, the second sealing member 42 can abut against the inner wall of the liquid inlet groove 61, at this time, the second sealing member 42 is in the closed position to close the second air passage 62.

[0117] After the brewing of the beverage liquid ends and the brewing device 10 and the brewing structure 20 perform the retreat action, the user can perform the milk frothing action through the milk frothing mechanism 104 to obtain milk froth, and the user can add the milk froth to the beverage liquid. At this time, the depth of the liquid inlet pipe 41 extending into the liquid inlet groove 61 is relatively reduced compared to when the second sealing member 42 is in the closed position, the second sealing member 42 is spaced apart from the inner wall of the liquid inlet groove 61, and is in the open position to open the second air passage 62. After the milk frothing mechanism 104 completes the milk frothing operation, the switching valve 105 can make the milk frothing mechanism 104 and the liquid inlet assembly 30 communicate, so that the gas, liquid and / or steam in the milk frothing mechanism 104 can flow through the liquid inlet assembly 30, the liquid inlet groove 61, the second through hole 714 and the second air passage 62 in turn, and be discharged to the external space.

[0118] In the embodiments of the present application, the number of the second seal 42 is not specifically limited. For example, the number of the second seal 42 can be multiple, and the multiple second seals 42 can be arranged in the vertical direction. When the second seal 42 is in the closed position, part of the second seal 42 can be located above the second through hole 714 and abut against the inner wall of the liquid inlet groove 61, and part of the second seal 42 can be located below the second through hole 714 and abut against the inner wall of the liquid inlet groove 61; in this way, the second seal 42 located on both sides of the second through hole 714 can separate the space above and below the second through hole 714, and block the communication between the second air channel 62 and the liquid inlet pipe 41 from both sides in the vertical direction.

[0119] It can be understood that the material of the second seal 42 can be the same as or similar to that of the first seal 52, and the principle of the second seal 42 separating the second air channel 62 from the liquid inlet groove 61 is the same as or similar to that of the first seal 52 separating the first air channel 54 from the exhaust pipe 51, which will not be described here.

[0120] It can be understood that the second air channel 62 can include a first part extending in the second direction and a second part extending in the vertical direction. One end of the first part of the second air channel 62 communicates with the second through hole 714, and the other end communicates with the second part. One end of the second part can penetrate the top of the connecting seat 71 to communicate with the external space.

[0121] In some embodiments, a second mounting groove 2214 can be formed in the brewing plug 221, and the second mounting groove 2214 can be located on the side of the first mounting groove 2213 away from the second receiving cavity 2212 and can communicate with the first mounting groove 2213. The bottom of the exhaust pipe 51 and the bottom of the liquid inlet pipe 41 can be fixedly connected to a base 110, which can be arranged on the periphery of the exhaust pipe 51 and the periphery of the liquid inlet pipe 41 and can relatively fix the exhaust pipe 51 and the liquid inlet pipe 41. The base 110 can be received in the second mounting groove 2214 and can be sealingly connected to the second mounting groove 2214 through a sealing ring.

[0122] It can be understood that the fixation of the base 110 to the exhaust pipe 51 and the liquid inlet pipe 41 allows the exhaust pipe 51 and the liquid inlet pipe 41 to be installed synchronously, thereby improving the convenience of installing the exhaust pipe 51 and the liquid inlet pipe 41.

[0123] It can be understood that the brewing mechanism 102 provided by the present application can realize the exhaust of the brewing cavity 11 when the brewing mechanism 102 brews beverage liquid, and can realize the discharge of gas, liquid and / or steam in the milk frothing mechanism 104 after the milk frothing mechanism 104 completes the milk frothing operation.

[0124] In some embodiments, the brewing structure 20 can further comprise a liquid outlet pipe 24. The liquid outlet pipe 24 can be arranged on the mounting member 21 and can extend in the vertical direction. The liquid outlet pipe 24 can be connected to a liquid pump (not shown) and the liquid outlet end 1011 through a pipe.

[0125] When the brewing structure 20 is close to the brewing device 10, one end of the liquid outlet pipe 24 can abut or plug into the brewing device 10 and communicate with the liquid outlet channel of the brewing device 10. After the beverage liquid is brewed, the liquid pump connected to the liquid outlet pipe 24 works, so that the beverage liquid can be transmitted to the liquid outlet pipe 24 through the liquid outlet channel and transmitted to the liquid outlet end 1011 through the liquid outlet pipe 24, so that the user can receive the beverage liquid at the liquid outlet end 1011.

[0126] Through the brewing mechanism 102 and the beverage machine 100 provided in the present application, when the brewing structure 20 moves into the brewing cavity 11 to be close to the beverage raw material and does not contact the beverage raw material, the first sealing member 52 is separated from the inner wall of the exhaust groove 53, the first sealing member 52 is located at the open position, and the gas in the brewing cavity 11 can be discharged to the external space through the exhaust pipe 51, the exhaust groove 53 and the first air passage 54.

[0127] After the brewing assembly 22 abuts against the beverage raw material, the mounting member 21 can move close to the brewing assembly 22, the exhaust pipe 51 and the first sealing member 52 move synchronously in the exhaust groove 53, and the liquid inlet pipe 41 and the second sealing member 42 move synchronously in the liquid inlet groove 61. When the first sealing member 52 moves to abut against the inner wall of the exhaust groove 53, the first sealing member 52 is at the closed position, and at this time, the second sealing member 42 also abuts against the inner wall of the liquid inlet groove 61, i.e., the second sealing member 42 is at the closed position; at the same time, the beverage raw material is compacted by the brewing assembly 22. At this time, the water injection mechanism 103 can input liquid to the liquid inlet assembly 30, the liquid can pass through the liquid inlet assembly 30, the liquid inlet groove 61 and the liquid inlet channel 411, push away the valve plug 80, and continue to flow into the brewing cavity 11 through the liquid inlet cavity 413 and the liquid outlet hole 2221, so as to extract the beverage liquid from the compacted beverage raw material.

[0128] Similarly, when the brewing structure 20 and the brewing device 10 perform the retreat action, the brewing assembly 22 and the mounting member 21 first move away from each other under the elastic driving of the powder pressing elastic member, so that the first sealing member 52 is separated from the inner wall of the exhaust pipe 51, i.e., the first sealing member 52 is switched to the open position, and then the brewing structure 20 continues to move out of the brewing cavity 11. At this time, the gas in the external space can enter the brewing cavity 11 through the first air passage 54, the exhaust groove 53 and the exhaust pipe 51.

[0129] Therefore, when the brewing structure 20 is extended into and moved out of the brewing chamber 11, and the second flow channel assembly 50 is in communication with the external space, the gas can flow between the brewing chamber 11 and the external space, thereby reducing the resistance of the gas pressure in the brewing chamber 11 to the movement of the brewing structure 20, improving the smoothness of the movement of the brewing structure 20 in the brewing chamber 11, reducing the load of the driving mechanism, thereby increasing the service life of the beverage machine 100.

[0130] Meanwhile, after the brewing structure 20 and the brewing device 10 complete the back-off action, the second sealing member 42 can be separated from the inner wall of the liquid inlet groove 61, that is, maintained in the open position. At this time, if the user makes milk foam through the milk frothing mechanism 104, after the milk frothing mechanism 104 completes the milk frothing operation, the switching valve 105 can communicate the milk frothing mechanism 104 with the liquid inlet assembly 30, thereby achieving pressure relief of the milk frothing mechanism 104, so that the gas, liquid and / or steam in the milk frothing mechanism 104 is discharged to the external space through the second gas channel 62. In this way, the milk frothing mechanism 104 can achieve pressure relief through the cooperation of the first flow channel assembly 40 and the third flow channel assembly 60, thereby not needing to additionally set a pressure relief structure, simplifying the structure of the milk frothing mechanism 104, and increasing the convenience of pressure relief of the milk frothing mechanism 104. Meanwhile, the cooperation of the first flow channel assembly 40 and the third flow channel assembly 60 for pressure relief of the milk frothing mechanism 104 can reduce the load of the milk frothing mechanism 104, reduce the failure rate of the milk frothing mechanism 104, and increase the service life of the beverage machine 100.

[0131] It is apparent for those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the above-described embodiments of the present application are to be considered in all aspects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended to embrace all changes and modifications that fall within the meaning and range of equivalents of the claims.
