[0002] As people's living standards improve, more and more people like to drink coffee. Adding milk foam to some coffee will improve the taste.

[0003] Many coffee machines are equipped with a milk frothing device for frothing milk. Existing milk frothing machines usually wind a thin steel wire around a ring to form multiple metal rings, and use the rotation of the metal rings to stir and cut the milk. Existing milk frothing machines have technical problems such as uneven stirring and difficulty in cleaning. Utility Model Content

[0004] The present application provides a milk frother and a coffee machine, which can solve the technical problems of uneven stirring and difficulty in cleaning of the milk frother in the prior art.

[0005] The present application provides a milk frother, which includes:

[0006] A runner, the runner comprising a body and blades; the body having an inner wall, the blades being arranged on the inner wall;

[0007] The screen is detachably connected to the bottom of the rotating wheel.

[0008] In the milk frothing machine provided by the present application, when the rotating wheel rotates, the blades extending into the milk cup stir the milk to produce foam, and the milk foam flows to the screen and is cut to form fine micro-foam. Since the blades are arranged on the inner wall of the body, the blades have a certain distance relative to the rotation center, thereby forming a larger stirring radius, so that the stirring is more uniform. The screen is detachably connected to the bottom of the rotating wheel, and can be easily removed, which is conducive to cleaning.

[0009] In a possible implementation, the blade is provided with an inclined surface, and the inclined surface is used to guide the liquid to flow toward the screen when the impeller rotates.

[0010] In the above solution, the blades are provided with inclined surfaces. When the wheel rotates, the inclined surfaces guide the milk liquid to flow toward the screen, thus playing a drainage role.

[0011] In a possible implementation, the blades are integrally formed on the inner wall of the body.

[0012] In the above solution, the blades are formed on the inner wall of the body through an integrated molding process, thereby simplifying the structure and making the molding process simpler.

[0013] In a possible implementation, there are multiple blades, and the multiple blades are evenly spaced and arranged on the inner wall of the body.

[0014] In the above scheme, the plurality of blades are arranged at equal intervals, which can make the stirring more uniform, thereby making the milk foam richer.

[0015] In a possible implementation, the rotating wheel further includes a fixing portion;

[0016] The milk foam machine also includes a main unit and a connecting rod, and two ends of the connecting rod are respectively connected to the fixing portion and the main unit.

[0017] In the above scheme, after the main machine is started, the main machine drives the connecting rod to rotate. Since the connecting rod is connected to the fixed part, it can drive the blades on the runner to rotate and stir. After the milk foam flows to the screen, it is cut into fine micro foam.

[0018] In a possible implementation, the rotating wheel further includes connecting ribs connected to the fixing portion and the body.

[0019] In the above scheme, when the connecting rod rotates, the fixed part rotates accordingly, and through the transmission of the connecting ribs, the main body and the blades also rotate accordingly, and the blades stir the milk.

[0020] In a possible implementation, a limiting portion is provided on the inner wall of the body;

[0021] The screen is provided with a clamping portion, and the limiting portion is clamped and matched with the clamping portion, so that the rotating wheel and the screen are detachably connected.

[0022] In the above solution, when the screen needs to be disassembled, the clamping part is disengaged from the limiting part, so that the screen and the rotating wheel can be disassembled. The cooperation between the limiting part and the clamping part can realize the detachable connection between the screen and the rotating wheel.

[0023] In a possible implementation, the screen includes a mesh body and an extension portion connected to the mesh body;

[0024] The clamping portion is a flange arranged on the extending portion;

[0025] The limiting portion is a groove formed on the inner wall of the body; the flange is snap-fitted with the groove.

[0026] In the above solution, the flange can be integrally formed on the extension portion, and the groove can be formed on the inner wall by machining. The clamping connection between the flange and the groove further simplifies the structure of the milk frother.

[0027] In a possible implementation manner, a notch is provided on the extension portion.

[0028] In the above scheme, the notch divides the extension part into multiple independent parts, so that the extension part has a certain elastic deformation space when the screen and the rotating wheel are assembled. During assembly, the extension part is pressed to extend a part of the screen into the rotating wheel, and the clamping part and the limiting part are engaged, so that the screen and the rotating wheel can be installed. During disassembly, the extension part is pressed to disengage the clamping part from the limiting part, and the screen is pulled out of the rotating wheel, so that the screen and the rotating wheel can be cleaned separately. The entire disassembly and assembly process is simple and easy to operate.

[0060] Figure 1 A schematic diagram of the structure of a milk frother provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the embodiment of the present application provides a milk frothing machine 100, which may include a main unit 30, and the main unit 30 is used as a power output source to provide power for stirring liquid. The milk frothing machine 100 may also include a sheath 50, which is connected to the main unit 30 and contains a stirring device of the milk frothing machine 100. When the milk frothing machine 100 is not needed, the sheath 50 can protect and isolate the stirring device.

[0061] Figure 2 This is a schematic diagram of the structure of the milk frother provided in the embodiment of the present application after the sheath is removed, as shown in FIG. Figure 2 As shown, the milk frother 100 includes a rotating wheel 10 and a screen 20. The rotating wheel 10 is used to stir milk to generate foam when rotating. The milk foam can form smooth and delicate micro-foam after flowing through the screen 20, thereby improving the taste of coffee. The rotating wheel 10 can be connected to the host 30 through a connecting rod 40. The host 30 drives the connecting rod 40 to rotate, thereby driving the rotating wheel 10 to rotate to stir the milk. This will be described in detail below.

[0062] Figure 3 This is a schematic diagram of the installation of the rotating wheel and the screen in the milk frothing machine provided in the embodiment of the present application, as shown in FIG. Figure 3 As shown, the wheel 10 includes a body 11 and blades 12, wherein the body 11 may be a circular metal ring, the body 11 has an inner wall 11a, and the blades 12 are arranged on the inner wall 11a and can rotate synchronously with the body 11. In a specific embodiment, the blades 12 may be integrally formed on the inner wall 11a of the body 11, and when the body 11 rotates, the blades 12 rotate accordingly, thereby stirring the milk.

[0063] The screen 20 is detachably connected to the bottom of the rotating wheel 10. When the screen 20 and the rotating wheel 10 need to be cleaned, the screen 20 can be removed from the bottom of the rotating wheel 10. After cleaning, the screen 20 can be installed on the bottom of the rotating wheel 10.

[0064] When in use, the protective cover 50 is first removed, the rotating wheel 10 and the screen 20 are inserted into the milk cup, the main unit 30 is turned on, and the connecting rod 40 is controlled to drive the rotating wheel 10 to rotate. The blades 12 on the rotating wheel 10 rotate to stir the milk at high frequency to produce milk foam.

[0065] In the milk frother 100 provided by the embodiment of the present application, when the wheel 10 rotates, the blades 12 stir the milk to generate foam, and the milk foam flows to the screen 20 and is cut to form fine micro-foam. Since the blades 12 are arranged on the inner wall 11a of the body 11, the blades 12 have a certain distance relative to the rotation center, thereby forming a larger stirring radius, so that the stirring is more uniform.

[0066] Figure 4 This is a schematic diagram of the structure of the rotating wheel in the milk frother provided in the embodiment of the present application, as shown in FIG. Figure 4 As shown, the blade 12 is provided with an inclined surface 12a, which can be a plane or a curved surface. The overall profile of the inclined surface 12a is inclined toward the screen 20. When the wheel 10 rotates, the inclined surface 12a guides the milk liquid to flow toward the screen 20, playing a role of drainage. In this embodiment, the cross section of the blade 12 forms a roughly triangular shape, so that the inclined surface 12a inclined downward can be formed.

[0067] As mentioned above, the blades 12 can be formed on the inner wall 11a of the body 11 by an integrated molding process, thereby simplifying the structure and making the molding process simpler. In other embodiments, the blades 12 can also be connected to the inner wall 11a of the body 11 by welding or other processes.

[0068] Continue to refer to Figure 4 In a specific embodiment, the number of blades 12 is multiple, and the multiple blades 12 are arranged on the inner wall 11a of the body 11 at equal intervals. Figure 4 In the embodiment shown, there are four blades 12, which are arranged opposite to each other on the inner wall 11a of the body 11. When the body 11 rotates, the blades 12 rotate accordingly. In this embodiment, the plurality of blades 12 are arranged at equal intervals, which can be more uniform during stirring, thereby making the milk foam richer.

[0069] Please continue to refer to Figure 3 The rotating wheel 10 also includes a fixing portion 14, and the milk frother also includes a main unit 30 and a connecting rod 40, and please also refer to Figure 2 As shown, both ends of the connecting rod 40 are respectively connected to the fixed part 14 and the main machine 30. After the main machine 30 is started, the main machine 30 drives the connecting rod 40 to rotate. The connecting rod 40 is connected to the fixed part 14, so that the connecting rod 40 drives the fixed part 14 to rotate, and then drives the blades 12 on the wheel 10 to rotate and stir the milk.

[0070] The fixing portion 14 may be Figure 3 The sleeve-shaped structure shown is an integral structure with the body 11. The fixing portion 14 may also be other structures or parts formed on the body 11, as long as it can transmit power to the wheel 10 with the connecting rod 40. In this embodiment, the fixing portion 14 is located at the center of the wheel 10, and the connecting rod 40 rotates to drive the wheel 10 to rotate, without eccentricity, so that the stirring is more uniform.

[0071] There is a certain distance between the fixing portion 14 and the end of the blade 12 so as to fully stir the milk.

[0072] like Figure 3As shown, the wheel 10 also includes a connecting rib 13, and the connecting rib 13 is connected between the fixing portion 14 and the body 11. In this embodiment, the fixing portion 14 is a sleeve-shaped structure located at the center of the wheel 10, and has a center hole. The connecting rod 40 is inserted and fixed in the center hole of the fixing portion 14. The connecting rib 13 can be an integrally formed structure with the body 11 and the fixing portion 14. When the host 30 drives the connecting rod 40 to rotate, the fixing portion 14 rotates accordingly. After the transmission of the connecting rib 13, the body 11 and the blades 12 also rotate accordingly, and the blades 12 stir the milk. In a specific embodiment, the blades 12 are provided with a downwardly inclined inclined surface 12a, which can make the milk have kinetic energy to flow from top to bottom. When passing through the screen 20, the milk foam is cut to form more delicate micro foam.

[0073] The number of the connecting ribs 13 may be two or more, so as to make the overall structure of the rotating wheel 10 more stable and firm. Figure 3 In the illustrated embodiment, there are four connecting ribs 13, which are evenly spaced and respectively connect the fixing portion 14 and the inner wall 11a of the body 11. It is understandable that each connecting rib 13 can be arranged between adjacent blades 12, so that the blades 12 and the connecting ribs 13 are distributed along the circumferential direction, and thus the height of the wheel 10 does not need to be increased to provide arrangement space, which is conducive to a more compact overall structure of the milk frother 100. Moreover, there is a certain distance between the connecting rib 13 and the blade 12, which can fully stir the milk.

[0074] like Figure 4 As shown, in a possible implementation manner, the inner wall 11 a of the body 11 is provided with a limiting portion 11 b , and the limiting portion 11 b is used to limit and fix the screen 20 .

[0075] Figure 5 A schematic diagram of the structure of the screen in the milk frother provided in the embodiment of the present application, as shown in FIG. Figure 5 As shown, the screen 20 is provided with a clamping portion 22a, which is combined with Figure 4 and Figure 5 As shown, the above-mentioned limiting portion 11b is engaged with the clamping portion 22a to make the rotating wheel 10 and the screen 20 detachably connected. When the screen 20 needs to be removed, the clamping portion 22a is removed from the limiting portion 11b to realize the removal of the screen 20 and the rotating wheel 10.

[0076] As an optional method, the screen 20 can be an integrally formed plastic part with screen holes formed thereon. The screen 20 can also be formed by combining a mesh part and a plastic part.

[0077] Optionally, the screen 20 includes a mesh body 21 and an extension portion 22 connected to the mesh body. The extension portion 22 can be formed as a whole into a circular ring structure, which can be inserted into the rotating wheel 10 so that the clamping portion 22a cooperates with the limiting portion 11b.

[0078] The clamping portion 22a may be a flange provided on the extension portion 22 , and the limiting portion 11b may be a groove formed on the inner wall 11a of the body 11 . The flange and the groove are clamped together to realize a detachable connection between the screen 20 and the wheel 10 .

[0079] In order to make the screen 20 easily inserted into the rotating wheel 10, the screen 20 may have a certain elastic deformation capability. Figure 5 Optionally, a notch 22b is provided on the extension portion 22. The notch 22b divides the extension portion 22 into a plurality of independent parts, so that the extension portion 22 has a certain elastic deformation space when the screen 20 is assembled with the runner 10. During assembly, the extension portion 22 is pressed to extend a portion of the screen 20 into the runner 10, and the clamping portion 22a is engaged with the limiting portion 11b, so that the screen 20 and the runner 10 can be installed. During disassembly, the extension portion 22 is pressed to disengage the clamping portion 22a from the limiting portion 11b, and the screen 20 is pulled out of the runner 10, so that the screen 20 and the runner 10 can be cleaned separately, and the entire disassembly and assembly process is simple and easy to operate.

[0080] The embodiment of the present application also provides a coffee machine, including a main body, and the coffee machine also includes a milk frother 100 provided in any embodiment of the present application, and the milk frother 100 is installed in the main body. When it is necessary to make milk froth, the milk frother 100 can be removed from the main body to make milk froth. After the milk froth is made, the milk frother 100 is cleaned and then installed in the main body.

[0081] In the milk frother and coffee machine provided by the embodiments of the present application, when the wheel is rotating, the blades extending into the milk cup stir the milk to produce foam, and the milk foam flows to the screen and is cut to form fine micro-foam. Since the blades are arranged on the inner wall of the body, the blades have a certain distance relative to the rotation center, thereby forming a larger stirring radius, so that the stirring is more uniform. The screen is detachably connected to the bottom of the wheel and can be easily removed, which is conducive to cleaning.

[0082] The above description is only the preferred embodiment of the present application and is not intended to limit the present application.
