[0035] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.
[0036] The utility model provides a milk frothing device 100 which can rotate in multiple directions. Figures 1 to 9 As shown, the multi-directionally rotatable milk frothing device 100 comprises a base 1 , a rotating member 2 and a milk frothing rod 3 .
[0037] The base 1 is provided with a swing arm 11, and the swing arm 11 is provided with a limit groove 111 with the top extending toward one side; the rotating member 2 includes a movable part 21 and a fixed part 22 connected to the movable part 21; the movable part 21 is movably arranged in the limit groove 111, and the movable part 21 can swing around a first axis relative to the limit groove 111, and specifically in this embodiment, the movable part 21 swings around the first axis along the top of the limit groove 111 to the side extending direction, that is, swings in the vertical direction; the milk whipping rod 3 is rotatably connected with the fixed part 22, and the milk whipping rod 3 can swing around the central axis of the fixed part 22 as a second axis, and the extension direction of the first axis intersects with the extension direction of the second axis. Specifically in this embodiment, the extension direction of the central axis of the fixed part 22 is the horizontal direction, and the milk whipping rod 3 swings around the central axis of the fixed part 22 as the second axis in the front-back direction, wherein it should be noted that the vertical direction and the front-back direction are both based on the direction of the three-dimensional coordinate system.
[0038] It can be understood that the milk frothing rod 3 is rotatably connected to the fixed part 22 of the rotating member 2, so that the milk frothing rod 3 can be driven to swing around the second axis as the central axis of the fixed part 22 under the action of external force, and the milk frothing rod 3 is movably set in the limiting groove 111 of the swing arm 11 of the machine base 1 through the movable part 21 of the rotating member 2, and the movable part 21 can swing around the first axis relative to the swing arm 11 of the machine base 1, and the extension direction of the first axis intersects with the extension direction of the second axis. Therefore, the milk frothing rod 3 can make multi-directional movements on the swing arm 11 around two staggered axes relative to the swing arm 11 of the machine base 1, which can make the milk frothing angle more and the milk foam more rich, and the height of the milk frothing rod 3 relative to the bottom of the machine base 1 can also be well adjusted to adapt to milk cups of different heights.
[0039] In some embodiments, such as Figure 4 and Figure 6 As shown, the groove wall of the limiting groove 111 is provided with a first clamping portion 112, and the movable part 21 is provided with a second clamping portion 211 adapted to the first clamping portion 112 along its own swinging direction. When the movable part 21 swings relative to the limiting groove 111, the second clamping portion 211 is engaged with the first clamping portion 112. It can be understood that the first clamping portion 112 is provided on the groove wall of the limiting groove 111, and the second clamping portion 211 is provided on the movable part 21. When the movable part 21 swings relative to the limiting groove 111, the second clamping portion 211 can form a hovering state when the second clamping portion 211 is in a state of being engaged with the first clamping portion 112, so that the movable part 21 and the fixed part 22 and the milk whipping stick 3 connected to the movable part 21 can hover at a fixed angle and form a gear sense when hovering.
[0040] Specifically in this embodiment, the first clamping portion 112 is a groove formed on the groove wall of the limiting groove 111, and a plurality of grooves are formed along the swinging direction of the movable portion 21, and the second clamping portion 211 is a protrusion formed on the movable portion 21; or, in another embodiment, as Figure 6 As shown, the first clamping portion 112 is a protrusion provided on the groove wall of the limiting groove 111, and the second clamping portion 211 is a groove provided on the movable portion 21, and a plurality of the grooves are provided along the swinging direction of the movable portion 21. It can be understood that by providing the groove and the protrusion for matching and snapping, on the one hand, it has the characteristics of simple structure, and on the other hand, it can form a good matching and snapping relationship. Specifically in this embodiment, when there are a plurality of grooves, there is a smooth transition between two adjacent grooves, so that the protrusion can smoothly move from the current groove to the next groove for snapping.
[0041] In some embodiments, such as Figure 5As shown, a rotation hole 212 is provided on the movable part 21, and a rotation shaft 113 is provided in the limiting groove 111. The rotation hole 212 of the movable part 21 is rotatably inserted into the rotation shaft 113. The movable part 21 reciprocates along the direction extending from the top of the limiting groove 111 to the side through the cooperation of the rotation hole 212 and the rotation shaft 113 to form a swinging motion, and the central axis of the rotation shaft 113 is the first axis. It can be understood that by setting the matching shaft-hole relationship between the rotation hole 212 and the rotation shaft 113, the movable part 21 can smoothly reciprocate along the direction extending from the top of the limiting groove 111 to the side to form a swinging motion.
[0042] In some embodiments, such as Figure 6 As shown, the movable part 21 is a cylindrical structure, and the limiting groove 111 is an arc-shaped groove structure adapted to the movable part 21, which can rotate smoothly relative to the limiting groove 111, and the limiting groove 111 forms a limiting effect on the movement of the movable part 21 to limit the swing amplitude of the movable part 21.
[0043] In some embodiments, such as Figure 7 As shown, a connection hole 31 is opened on the milk whipping rod 3 , and the milk whipping rod 3 is rotatably sleeved on the fixing portion 22 through the connection hole 31 , thereby limiting the milk whipping rod 3 from rotating around the central axis of the fixing portion 22 .
[0044] In some embodiments, the milk frothing stick 3 includes an upper shell 33 and a lower shell 34. When the upper shell 33 is connected to the lower shell 34, the fixing portion 22 is mounted to limit the milk frothing stick 3 to rotate only around the fixing portion 22. Specifically, in this embodiment, the upper shell 33 and the lower shell 34 are both provided with arc holes, wherein the fixing portion 22 is a cylindrical structure. When the upper shell 33 is connected to the lower shell 34, the two arc holes are mounted to form the connecting hole 31. The fixing portion 22 is mounted. The lower shell 34 is an inverted L-shaped structure. The specific structural setting of the lower shell 34 enables the end of the milk frothing stick 3 to swing forward and backward. With the aforementioned vertical swing, the milk frothing stick 3 can move in multiple directions, so that the angles of milk frothing are more and the milk foam is more concentrated. The height of the milk frothing stick 3 relative to the bottom of the machine can also be adjusted well to adapt to milk cups of different heights.
[0045] In some embodiments, such as Figure 7 and Figure 8As shown, the wall of the connecting hole 31 is provided with an elastic lever 32, and the peripheral wall of the fixing part 22 is provided with a plurality of slots 221. When the milk whipping stick 3 rotates relative to the fixing part 22, each of the slots 221 can be elastically engaged with the elastic lever 32 in sequence. It can be understood that during the rotation of the milk whipping stick 3, the elastic lever 32 of the milk whipping stick 3 can be elastically engaged with the slot 221, so that the milk whipping stick 3 can be suspended at a fixed angle and form a gear sense. Specifically in this embodiment, the elastic lever 32 includes an elastic member 321 and a limiting column 322; the wall of the connecting hole 31 is provided with a mounting hole 311, and the limiting column 322 is elastically arranged in the mounting hole 311 through the elastic member 321, wherein the elastic member 321 can be a spring, and the limiting column 322 is at least partially exposed in the mounting hole 311, and the end of the limiting column 322 exposed in the mounting hole 311 is in an arc shape. The arc-shaped limiting column 322 cooperates with the elastic property formed by the elastic member 321 to enable the limiting column 322 to slide from the clamping state of the previous clamping slot 221 to the clamping state of the subsequent clamping slot 221, so that the milk frothing stick 3 can smoothly rotate to the preset position for hovering.
[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, a receiving groove 114 is provided on the machine base 1, and the swing arm 11 is slidably arranged in the receiving groove 114, so that the swing arm 11 can extend out of the machine base 1 or be retracted into the machine base 1, and drive the milk frothing rod 3 to rotate and open to form a working state, or be retracted into the machine base 1 to form a storage state.
[0047] In some embodiments, such as Fig. 9 As shown, the milk whipping stick 3 includes a body 36 and a stirring body 37, wherein the stirring body 37 is rotatably connected to the body 36, and the body 36 is an internal hollow structure. A rotation drive device 38 is provided inside the body 36, and the output end of the rotation drive device 38 is connected to the stirring body 37 and drives the stirring body 37 to rotate relative to the body 36. In addition, a micro switch 39 and a button 35 electrically connected to the rotation drive device 38 are also provided on the body 36, and the button 35, the micro switch 39 and the rotation drive device 38 are installed in the body 36 from top to bottom. Furthermore, the swing arm 11 and the rotating member 2 are both hollow structures, so that the wires connecting the rotation drive device 38, such as the rotating motor and the micro switch 39, can be connected to the inside of the machine base 1.
[0048] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
