[0003] However, the existing milk foaming devices have many components. All the parts that the milk passes through need to be disassembled for cleaning. Disassembly and cleaning are very cumbersome. After drying, they need to be reassembled before use. There are many sanitary dead corners, which are not easy to clean thoroughly, and milk stains are prone to stink. Moreover, the milk is sucked up by a straw, and the straw requires special tools to be cleaned thoroughly. The entire structure has many parts, and disassembly and cleaning are cumbersome. Summary of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] The technical problem to be solved by the utility model is to provide a milk foaming device and a coffee machine. A main channel communicating with a mixing chamber and a milk inflow channel communicating with the main channel are provided on a milk container. The outer ends of the main channel and the milk inflow channel are open. After the milk container is removed from the milk bracket, the main channel and the milk inflow channel can be easily cleaned. After the milk container is assembled to the milk bracket, the main channel and the milk inflow channel can be closed, thus reducing many parts. Disassembly and cleaning are very convenient, and the milk straw is also eliminated.

[0006] (2) Technical Solutions

[0007] The solution adopted by the utility model to solve the above technical problems is a milk foaming device, which includes a milk bracket and a milk container assembled on the milk bracket for containing milk. Wherein, the milk container is provided with a mixing chamber and a main channel communicating with the mixing chamber. The two ends of the main channel along its flow direction are respectively provided with a mixing inlet communicating with the mixing chamber and a steam inlet communicating with a steam inflow channel. A milk inflow channel communicating with the main channel is provided downstream between the steam inlet and the mixing inlet of the main channel, and an air inlet is provided upstream between the steam inlet and the mixing inlet of the main channel. Moreover, the outer ends of the main channel and the milk inflow channel are open and can cooperate with the milk bracket to form the closed main channel and milk inflow channel. The milk bracket includes the steam inflow channel.

[0008] In some embodiments, the main channel and the milk inflow channel are integrally in a T-shape on the milk container.

[0009] Specifically, steam enters the steam inlet of the main channel through the steam inflow channel on the milk bracket. And on the path from the main channel to the mixing chamber, the rapid passage of steam will form a negative pressure area near the main channel in the milk inflow channel, so as to suck milk from the milk container and flow along the milk inflow channel towards the main channel, enabling the milk and steam to mix and flow towards the mixing chamber, where the air entering through the air inlet can be mixed, so that the steam, milk and air are fully and evenly mixed, thus forming delicate milk foam.

[0010] With the above solution, a main channel communicating with the mixing chamber and a milk inflow channel communicating with the main channel are provided on the milk container; the outer ends of the main channel and the milk inflow channel are open. After the milk container is disassembled from the milk bracket, the main channel and the milk inflow channel can be easily cleaned; and after the milk container is assembled to the milk bracket, the main channel and the milk inflow channel can be closed, thus reducing many parts, making disassembly and cleaning very convenient, and also eliminating the milk straw.

[0011] In some embodiments, a first milk inlet and a second milk inlet are respectively arranged along the flowing direction of the milk inflow channel. The first milk inlet communicates with the milk container, and the second milk inlet communicates with the main channel; and the first milk inlet is relatively arranged downstream of the second milk inlet.

[0012] With the above solution, on the path of the steam flowing along the main channel towards the mixing chamber, due to the rapid passage of the steam, a negative pressure area will be formed near the second milk inlet in the milk inflow channel, sucking the milk in the milk container into the first milk inlet, flowing along the milk inflow channel towards the main channel, and entering the main channel through the second milk inlet to be mixed with the steam.

[0013] In some embodiments, the main channel is sequentially provided with a first channel, a second channel and a third channel along its flowing direction. The first channel communicates with the steam inflow channel, the second channel communicates with the milk inflow channel, and the third channel communicates with the air inlet; and, the size of the second channel in the width direction is smaller than the size of the first channel in the width direction, and the size of the third channel in the width direction gradually increases along the flowing direction.

[0014] In some embodiments, the second channel communicates with the second milk inlet.

[0015] With the above solution, since the path at the second channel and the second milk inlet suddenly becomes narrower compared to the first channel, the steam pressure passing through will increase and the speed will become faster. As a result, a negative pressure area will be formed near the second milk inlet in the milk inflow channel, and the milk can be sucked into the main channel and mixed with the steam. After the steam is mixed with the milk and enters the third channel, it will be mixed with the air entering from the air inlet in the third channel and then enter the mixing chamber, enabling the steam, milk, and air to be fully and evenly mixed, thereby forming delicate milk foam. At the same time, due to the large size of the first channel, the steam flowing into the channel will impact the outer wall of the milk container placed in the first channel, thereby reducing the impact force of the steam and making its flow smoother.

[0016] In some embodiments, the outer wall of the milk container bulges outward to form a protruding wall, and the main channel and the milk inflow channel are formed inside the protruding wall; moreover, the air inlet is provided on the protruding wall along its protruding direction.

[0017] In some embodiments, the protruding wall is in a T shape on the milk container.

[0018] In some embodiments, the outer wall of the milk container is recessed inward to form the mixing chamber, and the main channel communicates with the mixing chamber through the mixing inlet.

[0019] In some embodiments, the mixing chamber and the protruding wall are respectively provided on two side walls of the milk container, and the two side walls intersect. Then, by opening a mixing inlet at one end of the main channel, the main channel and the mixing chamber can be connected.

[0020] In some embodiments, a nozzle member is connected to one end of the mixing chamber away from the milk container.

[0021] In some embodiments, the outer wall of the milk container bulges outward along the periphery of the mixing chamber to form a mounting wall, and the nozzle member is rotatably connected to the mounting wall, so that the angle of the nozzle member can be adjusted to adapt to cup bodies of different heights.

[0022] With the above solution, the inside of the nozzle member communicates with the mixing chamber to discharge the mixed milk foam from the nozzle member.

[0023] In some embodiments, a sealing member is provided between the milk bracket and the milk container, and the sealing member can seal the main channel and the milk inflow channel; moreover, a perforation is provided on the sealing member to communicate the steam inflow channel and the main channel.

[0024] In some embodiments, the milk bracket is provided with a receiving groove for receiving the sealing member.

[0025] In some embodiments, the seal is T-shaped to fit the main channel and the milk inlet channel; then the receiving groove is also T-shaped to snap the seal onto the milk holder, making the seal between the milk container and the milk holder better.

[0026] With the above solution, the setting of the seal can improve the seal between the main channel and the milk inlet channel to prevent milk leakage.

[0027] In some embodiments, the milk holder includes a main holder that can wrap part of the outer wall of the milk container, and a base provided at the bottom of the main holder to support the milk container; an opening is provided at the top of the milk container, and a lid is connected to the opening, and the lid can close or open the opening.

[0028] In some embodiments, a limiting portion for restricting the axial movement and radial movement of the milk container is provided at the top of the main holder, and a radial limiting portion for restricting the radial movement of the milk container is provided on the base.

[0029] In some embodiments, the limiting portion includes an inverted shaft body formed at the top of the main holder, and a recess is provided at the bottom of the shaft body. Correspondingly, a protrusion that can be adapted to the recess is provided at the top of the milk container; through the cooperation of the protrusion and the recess, the top of the milk container is locked on the main holder; the radial limiting portion includes a jack formed on the base, and correspondingly, a plug that can be adapted to the jack is provided at the bottom of the milk container; through the cooperation of the plug and the jack, the bottom of the milk container is locked on the base; thus, after the milk container is assembled to the milk holder, the fastening degree is high, it is not easy to separate, and the structure is simple, which is conducive to disassembly and assembly and convenient for subsequent cleaning.

[0030] The solution adopted by the present utility model to solve the above technical problems is a coffee machine, including the milk foaming device as described above.

[0031] In some embodiments, the coffee machine includes a machine body, a steam generator is provided in the machine body, and an outlet of the steam generator communicates with a steam inlet channel of the milk foaming device located on the milk holder to provide steam for milk foaming; the machine body is further provided with a coffee brewing device, and the coffee brewing device has a coffee liquid outlet, and an outlet of a nozzle member of the milk foaming device is arranged close to the coffee liquid outlet; and, since the nozzle member can rotate, the position of the outlet of the nozzle member can be adjusted according to the height of the cup body, so that the milk foam can better flow into the cup body and will not splash.

[0060] Embodiment 1:

[0061] As Figures 1 - 12As shown, this embodiment provides a milk foaming device, including a milk bracket 101 and a milk container 102 assembled on the milk bracket 101 for containing milk. Among them, the milk container 102 is provided with a mixing chamber 103 and a main channel 104 communicating with the mixing chamber 103. At both ends of the main channel 104 along its flow direction, there are respectively a mixing inlet 1041 communicating with the mixing chamber 103 and a steam inlet 1042 communicating with a steam inflow channel 1011. Downstream of the main channel 104 between the steam inlet 1042 and the mixing inlet 1041, there is a milk inflow channel 105 communicating with the main channel 104. Upstream of the main channel 104 between the steam inlet 1042 and the mixing inlet 1041, there is an air inlet 1043. And the outer ends of the main channel 104 and the milk inflow channel 105 are open, and can cooperate with the milk bracket 101 to form the closed main channel 104 and milk inflow channel 105. The milk bracket 101 includes the steam inflow channel 1011. In some embodiments, the main channel 104 and the milk inflow channel 105 are integrally in a T shape on the milk container 102. Specifically, steam enters the steam inlet 1042 of the main channel 104 through the steam inflow channel 1011 on the milk bracket 101. And on the path from the main channel 104 flowing towards the mixing chamber 103, the rapid passage of steam will form a negative pressure area 1053 near the main channel 104 in the milk inflow channel 105, so as to suck milk from the milk container 102 and flow along the milk inflow channel 105 towards the main channel 104 direction, making the milk and steam mix, and flow towards the mixing chamber 103 direction, and can mix the air entering from the air inlet 1043, so that the steam, milk and air are fully and evenly mixed, thus forming delicate milk foam. Adopting the above scheme, on the milk container 102, there are provided a main channel 104 communicating with the mixing chamber 103 and a milk inflow channel 105 communicating with the main channel 104. The outer ends of the main channel 104 and the milk inflow channel 105 are open. After disassembling the milk container 102 from the milk bracket 101, the main channel 104 and the milk inflow channel 105 can be easily cleaned. And after assembling the milk container 102 to the milk bracket 101, the main channel 104 and the milk inflow channel 105 can be closed, thus reducing a lot of parts, and the disassembly and cleaning are very convenient, and the milk straw is also cancelled.

[0062] In some embodiments, a first milk inlet 1051 and a second milk inlet 1052 are respectively arranged along the flowing direction of the milk inflow channel 105. The first milk inlet 1051 communicates with the milk container 102, and the second milk inlet 1052 communicates with the main channel 104; and the first milk inlet 1051 is relatively arranged downstream of the second milk inlet 1052. With the above solution, on the path where the steam flows along the main channel 104 towards the mixing chamber 103, due to the rapid passage of the steam, a negative pressure area 1053 will be formed near the second milk inlet 1052 of the milk inflow channel 105, sucking the milk in the milk container 102 into the first milk inlet 1051, flowing along the milk inflow channel 105 towards the main channel 104, and entering the main channel 104 through the second milk inlet 1052 to be mixed with the steam.

[0063] In some embodiments, a first channel 1044, a second channel 1045 and a third channel 1046 are sequentially arranged along the flowing direction of the main channel 104. The first channel 1044 communicates with the steam inflow channel 1011, the second channel 1045 communicates with the milk inflow channel 105, and the third channel 1046 communicates with the air inlet 1043; and, the size of the second channel 1045 in the width direction is smaller than the size of the first channel 1044 in the width direction, and the size of the third channel 1046 in the width direction gradually increases along the flowing direction. In some embodiments, the second channel 1045 communicates with the second milk inlet 1052. With the above solution, since the path at the second channel 1045 and the second milk inlet 1052 suddenly becomes narrower compared to the first channel 1044, the steam pressure passing through will increase and the speed will become faster, thereby forming a negative pressure area 1053 near the second milk inlet 1052 of the milk inflow channel 105, so that the milk can be sucked into the main channel 104 to be mixed with the steam; and after the steam is mixed with the milk and enters the third channel 1046, it will be mixed with the air entering through the air inlet 1043 in the third channel 1046 and then enter the mixing chamber 103, making the steam, milk and air fully and evenly mixed, thereby forming delicate milk foam; at the same time, since the size of the first channel 1044 is large, the steam entering from the steam inflow channel 1011 will impact the outer wall of the milk container 102 placed in the first channel 1044, thereby reducing the impact force of the steam and making its flow smoother.

[0064] In some embodiments, an outwardly protruding raised wall 1021 is formed on the outer wall of the milk container 102, and the main channel 104 and the milk inflow channel 105 are formed within the raised wall 1021; moreover, an air inlet 1043 is provided along the protruding direction of the raised wall 1021. In some embodiments, the raised wall 1021 is in a T shape on the milk container 102. In some embodiments, an inwardly concave mixing chamber 103 is formed on the outer wall of the milk container 102, and the main channel 104 communicates with the mixing chamber 103 through the mixing inlet 1041. In some embodiments, the mixing chamber 103 and the raised wall 1021 are respectively provided on two side walls of the milk container 102, and the two side walls intersect. Then, by opening a mixing inlet 1041 at one end of the main channel 104, the main channel 104 and the mixing chamber 103 can be connected.

[0065] In some embodiments, a nozzle member 106 is connected to one end of the mixing chamber 103 away from the milk container 102. In some embodiments, an installation wall 1023 is formed on the outer wall of the milk container 102 to protrude outward along the periphery of the mixing chamber 103, and the nozzle member 106 is rotatably connected to the installation wall 1023, so that the angle of the nozzle member 106 can be adjusted to adapt to cups of different heights. With the above solution, the interior of the nozzle member 106 communicates with the mixing chamber 103 to allow the mixed milk foam to flow out from the nozzle member 106.

[0066] In some embodiments, a seal 107 is provided between the milk holder 101 and the milk container 102, and the seal 107 can seal the main channel 104 and the milk inflow channel 105; moreover, a perforation 1071 is provided on the seal 107 to communicate the steam inflow channel 1011 and the main channel 104. In some embodiments, the milk holder 101 is provided with a receiving groove 1017 for receiving the seal 107. In some embodiments, the seal 107 is in a T shape to fit the main channel 104 and the milk inflow channel 105; then the receiving groove 1017 is also in a T shape to snap the seal 107 onto the milk holder 101, making the seal between the milk container 102 and the milk holder 101 better. With the above solution, the provision of the seal 107 can improve the seal of the main channel 104 and the milk inflow channel 105 to prevent milk from leaking out.

[0067] In some embodiments, the milk holder 101 includes a main holder 1012 capable of covering an outer wall of a part of the milk container 102, and a base 1013 provided at a bottom end of the main holder 1012 for supporting the milk container 102; an opening 1022 is provided at a top end of the milk container 102, and a cover 1014 is connected to the opening 1022, and the cover 1014 can close or open the opening 1022. In some embodiments, a limiting part 1015 for restricting axial movement and radial movement of the milk container 102 is provided at a top end of the main holder 1012, and a radial limiting part 1016 for restricting radial movement of the milk container 102 is provided on the base 1013. In some embodiments, the limiting part 1015 includes an inverted shaft body 1015a formed at the top end of the main holder 1012, and a recessed part 1015b is provided at a bottom end of the shaft body 1015a. Correspondingly, a protruding part 1024 capable of being adapted to the recessed part 1015b is provided at the top end of the milk container 102; through the cooperation of the protruding part 1024 and the recessed part 1015b, the top end of the milk container 102 is locked on the main holder 1012; the radial limiting part 1016 includes a socket 1016a formed on the base 1013.
