Figure 5 A schematic cross-sectional structure diagram of a pipeline assembly provided in an embodiment of the present application, Figure 6 A cross-sectional structural diagram of a mixing assembly provided in an embodiment of the present application is shown in FIG. Figures 1 to 6As shown, the mixing assembly 3 is used to mix steam, air and milk to generate milk froth. The mixing assembly 3 is provided with a mixing chamber 31, a mixing air inlet pipe 32, a milk inlet pipe 33 and a milk froth outlet 34. The air inlet pipe 11, the air delivery pipe 21, the mixing air inlet pipe 32 and the mixing chamber 31 are connected in sequence, the steam inlet pipe 12, the steam delivery pipe 22 and the mixing chamber 31 are connected in sequence, and the milk inlet pipe 33 is connected to the mixing chamber 31. The steam, air and milk are mixed in the mixing chamber 31. A constriction portion 311 for forming milk froth is provided in the middle of the mixing chamber 31. The steam, air and milk form milk froth under the action of the constriction portion 311 and output it. The milk froth outlet 34 is used to output hot milk or milk froth from the mixing chamber 31.
[0038] The beneficial effect brought about by the above implementation method is that the present milk frother improves the stability of the connection between the joint assembly, the pipeline assembly and the mixing assembly through a modular connection method, and can reduce the number of pipelines connecting the joint assembly, the pipeline assembly and the mixing assembly, thereby improving the sealing performance of the milk frother.
[0039] In some implementations, the air intake pipe 11 is connected to a solenoid valve for controlling the opening and closing state of air circulation.
[0040] Structurally, the air intake pipe 11 is connected with a solenoid valve for controlling the opening and closing state of air circulation, so that the air intake pipe 11 can stop inputting air by closing the solenoid valve, thereby heating the milk only by steam, and the milk frother outputs hot milk.
[0041] The beneficial effect brought about by the above implementation is that when the air input is stopped by closing the electromagnetic valve, the milk is heated only by steam, so that the hot milk can be easily output.
[0042] The beneficial effect brought about by the above implementation is that the milk frother can be used as a hot milk heating device and can also be used to generate milk foam, thereby improving the integration level of the milk frother.
[0043] In some implementations, the air intake pipe 11 and the steam intake pipe 12 are arranged parallel to each other, and the air delivery pipe 21 and the steam delivery pipe 22 are arranged parallel to each other.
[0044] like Figure 2 As shown, structurally, the air intake pipe 11 and the steam intake pipe 12 are arranged parallel to each other, which simplifies the structure of the air delivery pipe 21 and the steam delivery pipe 22, and facilitates the mutual docking of the air intake pipe 11 and the air delivery pipe 21, and the mutual docking of the steam intake pipe 12 and the steam delivery pipe 22, thereby improving the convenience of assembling the milk frother.
[0045] The beneficial effect brought about by the above implementation method is that the structures of the air delivery pipe and the steam delivery pipe are simplified, and the convenience of assembling the milk frother is improved.
[0046] In some implementations, a blocking portion 221 is provided on the outer side wall of the steam delivery pipe 22 , and the blocking portion 221 is used to prevent milk foam from entering the mixing air inlet pipe 32 .
[0047] Figure 3 for Figure 2 A schematic diagram of the local structure of a milk frothing device at A, such as Figure 3 As shown, structurally, a blocking portion 221 is provided on the outer wall of the steam delivery pipe 22 . The blocking portion 221 may be a raised structure and is used to prevent milk foam from entering the mixing air intake pipe 32 , thereby improving the cleanliness of the mixing air intake pipe 32 .
[0048] The beneficial effect brought about by the above implementation method is that the cleanliness of the mixing intake pipe during use is improved.
[0049] In some implementations, the pipe assembly 2 is provided with a first claw 201 and a second claw 202, and the mixing assembly 3 is provided with an arc-shaped first slot 301, an arc-shaped second slot 302 and a baffle 303. The first claw 201 can extend into the first slot 301 through one end of the first slot 301, and the second claw 202 can extend into the second slot 302 through one end of the second slot 302. When the pipe assembly 2 and the mixing assembly 3 rotate relative to each other, the first claw 201 can slide along the first slot 301, and the second claw 202 can slide along the second slot 302, and the first claw 201 and the second claw 202 can be limited by the baffle 303.
[0050] Figure 7 This is a schematic diagram of the three-dimensional structure of a milk frothing machine provided in an embodiment of the present application at a first viewing angle. Figure 8 A schematic diagram of the three-dimensional structure of a milk frothing machine provided in an embodiment of the present application at a second viewing angle is shown in FIG. Figures 7 and 8 As shown, the pipe assembly 2 is provided with a first clamping claw 201 and a second clamping claw 202 , and the first clamping claw 201 and the second clamping claw 202 are used to fix the pipe assembly 2 .
[0051] like Figures 7 and 8As shown, the mixing component 3 is provided with an arc-shaped first slot 301, an arc-shaped second slot 302 and a baffle 303, the first claw 201 can extend into the first slot 301 through one end of the first slot 301, and the second claw 202 can extend into the second slot 302 through one end of the second slot 302. When the pipe component 2 and the mixing component 3 rotate relative to each other, the first claw 201 can slide along the first slot 301, and the second claw 202 can slide along the second slot 302, and then the first claw 201 and the second claw 202 can be limited by the baffle 303, so that the pipe component 2 and the mixing component 3 can be connected and fixed by mutual rotation, or the pipe component 2 and the mixing component 3 can be disassembled by relative rotation.
[0052] The beneficial effect brought about by the above implementation method is that the pipeline assembly and the mixing assembly can be connected and fixed by rotating relative to each other, or the pipeline assembly and the mixing assembly can be disassembled by relative rotation, which facilitates the installation and disassembly of the pipeline assembly and the mixing assembly.
[0053] In some implementations, a silicone connecting tube 23 is provided at the end of the air delivery tube 21 , and a hollow air delivery duct is provided on the silicone connecting tube 23 .
[0054] like Figure 5 As shown, a silicone connecting tube 23 is provided at the end of the air delivery pipe 21. The silicone connecting tube 23 has a certain elasticity and is used to seal the connection between the air delivery pipe 21 and the mixing intake pipe 32. A hollow air delivery duct is provided on the silicone connecting tube 23 to ensure the sealing effect of the connection between the air delivery pipe 21 and the mixing intake pipe 32.
[0055] Exemplarily, corresponding silicone connecting tubes may also be provided at the connection points of other pipelines to improve the sealing performance of the pipelines.
[0056] The beneficial effect brought about by the above implementation method is that the sealing performance of the pipeline connection is ensured by the silicone connecting tube.
[0057] In some implementations, an annular sealing ring 231 is provided at the end of the silicone connecting tube 23 , and the sealing ring 231 extends from the end of the silicone connecting tube 23 to the middle of the silicone connecting tube 23 to form a constricted structure.
[0058] like Figure 5As shown, structurally, an annular sealing ring 231 is provided at the end of the silicone connecting tube 23, and the sealing ring 231 extends from the end of the silicone connecting tube 23 to the middle of the silicone connecting tube 23 to form a contraction structure. The annular sealing ring 231 can be compressed toward the silicone connecting tube 23 when squeezed, and can ensure that the sealing ring 231 is tightly fitted with the end of the mixing intake pipe 32 under the pressure of air pressure, thereby improving the sealing performance of the mixing intake pipe 32 and the sealing ring 231.
[0059] The beneficial effect brought about by the above implementation method is that the sealing ring can fit tightly with the end of the mixing intake pipe under the pressure of air pressure, thereby improving the sealing performance of the mixing intake pipe and the sealing ring.
[0060] In some implementations, the mixing air inlet pipe 32 and the milk inlet pipe 33 are staggered.
[0061] like Figure 6 As shown, structurally, the mixing air inlet pipe 32 and the milk inlet pipe 33 are staggered so that the air entering through the mixing air inlet pipe 32 and the milk entering through the milk inlet pipe 33 will not collide with each other, and the milk can smoothly enter the mixing chamber 31 under the action of the negative pressure generated by the steam, thereby ensuring the mixing chamber 31's suction effect on the milk.
[0062] The beneficial effect brought about by the above implementation method is that the suction effect of the mixing chamber on milk is guaranteed.
[0063] In some implementations, the connector assembly 1 and the pipe assembly 2 are detachably connected via a snap-fit.
[0064] like Figure 1 As shown, the connector assembly 1 and the pipe assembly 2 are detachably connected via a snap, so that the connector assembly 1 and the pipe assembly 2 are easy to disassemble and clean.
[0065] The embodiment of the present application further provides a coffee machine, which includes any of the above-mentioned milk frothers. The coffee machine can improve the pipeline sealing performance of the coffee machine through the milk frother, simplify the pipeline connection structure of the coffee machine, and improve the use effect of the coffee machine.
