[0029] To further elaborate on the technical means and effects adopted by the present application to achieve the predetermined purpose, the following describes in detail the specific embodiments, structures, features, and effects according to the present application in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0030] Combined Figures 1-4 As shown in the figure, the present invention discloses a multifunctional mother and baby machine, which includes a base 1 with a built-in motor 11, a milk shaking cylinder 2 and a milk bottle sleeve 3. The milk shaking cylinder 2 is arranged on the base 1 and is in transmission connection with the motor 11, and the milk shaking cylinder 2 has a milk shaking cavity 21 with an upward opening; the milk bottle sleeve 3 includes a sleeve base 31 with a built-in battery 318, a sleeve body 32 arranged on the sleeve bottom 31, a containing cavity formed by the sleeve bottom 31 and the sleeve body 32 together for placing the milk bottle 9, and a heating element 323 arranged in the sleeve base 31 or / and the sleeve body 32. The heating element 323 is electrically connected to the battery 318 to provide a heating and warming function for the milk bottle 9 placed in the containing cavity; the milk bottle sleeve 3 is detachably arranged relative to the milk shaking cylinder 2. A first connecting part is arranged at the bottom of the milk shaking cavity 21, and a second connecting part 311 is arranged at the bottom of the sleeve base 31. When the sleeve base 31 is arranged in the milk shaking cavity 21, the second connecting part 311 is in transmission and assembly connection with the first connecting part.

[0031] A first switch 319 is also arranged on the sleeve bottom 31 and is connected in series between the battery 318 and the heating element 323. When the first switch 319 is turned on, the heating element 323 gets electricity and starts to heat, providing warming for the milk bottle 9 placed in the containing cavity of the milk bottle sleeve 3. Since the battery 318 is built in the milk bottle sleeve 3, the milk bottle sleeve 3 can be separately made into a portable automatic milk warmer for the convenience of users.

[0032] A second switch 19 is arranged on the base 1, and the second switch 19 is connected in series between the motor 11 and the power supply. Among them, the power supply can be either an external power supply (such as mains electricity) or the battery 318. That is, the motor 11 in the base 1 can be electrically connected to the external power supply through a power cord or powered by the battery 318 on the milk bottle sleeve 3. For example, a first electrical connection piece is arranged on the sleeve bottom 31, and a second connection piece electrically connected to the motor 11 is arranged on the milk shaking cylinder 2. When the milk bottle sleeve 3 is assembled in the milk shaking cavity 21 through the sleeve bottom 31, the first electrical connection piece is electrically connected to the second connection piece, so that the battery 318 can also supply power to the motor 11. Therefore, when the second switch 19 is turned on, the milk shaking cylinder 2 rotates to provide an automatic milk shaking function for the milk bottle sleeve 3.

[0033] Therefore, the mother and baby machine disclosed by the present invention adopts a separable structure for the milk bottle sleeve 3 relative to the milk shaking cylinder 2 on the base 1, so that the milk bottle sleeve 3 can be assembled on the milk shaking cylinder 2 as needed, so that the mother and baby machine has multiple usage functions:

[0034] 1. The mother-infant machine is used as an automatic milk-shaking machine: insert the bottom 31 of the bottle sleeve 3 into the milk-shaking cavity 21, and connect the first connecting part 311 with the second connecting part through a transmission assembly, so that the bottle sleeve 3 is connected to the milk-shaking barrel 2 through a transmission, and the motor 11 in the machine base 1 drives the milk-shaking barrel 2 to rotate, thereby driving the bottle sleeve 3 to rotate, so that the milk bottle 9 placed in the accommodating cavity rotates, providing automatic milk shaking for the milk bottle 9 placed in the accommodating cavity, instead of manual milk shaking to make the milk powder brewed and mixed evenly.

[0035] 2. Use the bottle sleeve 3 alone: Take the bottle sleeve 3 out of the milk shaker 2. The bottle sleeve 3 can be used as a bottle carrier to facilitate users to carry bottles. At the same time, since the electric heating element 323 is arranged in the sleeve body 32, the bottle sleeve 3 can be used alone as an automatic milk warmer.

[0036] The sleeve body 32 includes an elastic connector 322 and a sleeve body sub-piece 321 connected to two opposite vertical sides of the elastic connector 322. The electric heating element 323 is arranged in the sleeve base 31 and / or the sleeve body sub-piece 321. There are multiple sleeve body sub-pieces 321 and elastic connectors 322, and one elastic connector 322 is connected between adjacent vertical sides of two adjacent sleeve body sub-pieces 321. Under the elastic force of the elastic connector 322, the size of the accommodating cavity is variable, so that the bottle accommodating cavity can accommodate bottles of different diameters. Specifically, the elastic connecting piece 322 generates a gathering elastic force on the sleeve body part 321 toward the central axis of the elastic connecting piece 322, so that the sleeve body 32 can generate a gathering elastic force on the milk bottle 9. Within the allowable range, when a milk bottle of any diameter is placed in the accommodating cavity, the sleeve body 32 can be tightly attached to the milk bottle under the action of the gathering elastic force to prevent the milk bottle from falling. It also provides heat conduction performance between the milk bottle 9 and the electric heating element 323 arranged on the sleeve bottom and / or the sleeve body part to improve the heating efficiency of warm milk.

[0037] For example, the elastic connecting member 322 is a rubber band or a silicone band, and the sleeve body member 321 is a cloth. Under the elastic force of the rubber band or the external force, the diameter of the accommodating cavity of the bottle sleeve 3 changes, so that the accommodating cavity can accommodate bottles of different diameters.

[0038] In one embodiment, the body part 321 includes a heat insulation layer and a heat conductive layer located on the inner side of the heat insulation layer; each body part 321 is provided with an electric heating element 323, and the electric heating element 323 is arranged between the heat insulation layer and the heat conductive layer. The inner layer of the body part 321 is a heat conductive layer made of a material with good thermal conductivity to improve the heat conduction efficiency between the heating element and the milk bottle, and the outer layer is a heat insulation layer to reduce the heat dissipation of the heating element to improve the heat utilization rate of the heating element.

[0039] Especially see Figure 5 and Figure 6The illustrated embodiment. The body 32 of the bottle holder includes a body sub-component 321 and an adjusting component 324. The body sub-component 321 is provided with at least one slit extending from the top opening of the body 32 towards the bottom 31 of the bottle holder. The adjusting component 324 is disposed at the slit to adjust the size of the top opening of the body 32 by adjusting the slit, so that the size of the accommodating cavity of the bottle holder 3 can be changed to meet the needs of placing bottles of different sizes.

[0040] For example, the adjusting component 324 is a zipper assembly. The zipper chain of the zipper assembly is disposed at the slit and extends along the extending direction of the slit. The zipper head of the zipper assembly moves along the extending direction of the zipper chain on the zipper chain, thereby changing the size of the slit.

[0041] In another embodiment, the adjusting component 324 is a magic tape.

[0042] Thus, it can be seen that the size of the body 32 of the bottle holder 3 can be changed and can be used in combination with bottles of different sizes, thus facilitating the use by users.

[0043] Further in combination with Figures 7-10 As shown. The first connecting portion includes a plurality of driving teeth 41 provided at the bottom of the milk shaking cavity 21. The plurality of driving teeth 41 are evenly spaced and arranged on a first circumference with a radius R. There is a driving groove 42 between any two adjacent driving teeth 41. The groove pitches D of any two adjacent driving grooves 42 on the first circumference are equal, and a first guiding inclined surface 411 is provided on the side of each driving tooth 41 close to the driving groove 42. The second connecting portion 311 includes a plurality of positioning buttons 311 provided at the bottom of the socket 31. The plurality of positioning buttons 311 are spaced apart on a second circumference with a radius R. The distance between two adjacent positioning buttons 311 on the second circumference is N times the groove pitch D (N is a natural number), and the lower end of each positioning button 311 has a second guiding inclined surface 312 that cooperates with the first guiding inclined surface 411.

[0044] The size of the first circumference formed by the distribution of the plurality of driving teeth 41 located at the bottom of the milk shaking cavity 21 is the same as the size of the second circumference formed by the arrangement and distribution of the plurality of positioning buttons 311, ensuring that when the socket 31 of the bottle holder 3 is inserted into the milk shaking cavity 21 of the milk shaker 2, the second guiding inclined surface 312 of each positioning button 311 can contact the first guiding inclined surface 411 of the corresponding driving tooth 41. At the same time, since the distance between two adjacent positioning buttons 311 on the second circumference is N times the groove pitch D (N is a natural number), each positioning button 311 can be engaged with the corresponding driving groove 42 at the same time, providing a condition for the bottle holder 3 to be inserted into the milk shaking cavity 21 of the milk shaker 2 in any orientation without alignment and realizing the transmission assembly with the milk shaker 2 by the engagement connection between the positioning button 311 and the driving groove 42.

[0045] Therefore, the present invention provides that when the milk bottle cover 3 is assembled with the milk shaker 2, it can be quickly positioned, and there is no need to specifically align the positions when putting it in. It can achieve drive assembly connection at any angle, simplifying the assembly for convenient use. At the same time, the present invention sets a plurality of positioning buckles 311, and uses the plurality of positioning buckles 311 to engage and connect with the transmission teeth 41 at corresponding positions to achieve multi-point transmission, ensuring the reliability of the drive assembly connection between the milk bottle cover 3 and the milk shaker 2, ensuring stable transmission so that the milk shaker 2 can drive the milk bottle cover 3 to rotate stably, which is beneficial to improving the use experience of the mother and baby machine.

[0046] During use, insert the socket 31 of the milk bottle cover 3 into the milk shaking cavity 21 of the milk shaker 2. Since the distance between two adjacent positioning buckles 311 on the second circumference is N times the slot pitch D, it can be ensured that the second guiding slope 312 of each positioning buckle 311 will surely contact the first guiding slope 411 of the transmission tooth 41 at the corresponding position. By using the cooperation between the first guiding slope 411 and the second guiding slope 312, each positioning buckle 311 slides into a transmission slot 42 at the corresponding position, thus realizing the meshing and driving connection between the milk bottle cover 3 and the transmission slots 42 at the bottom of the milk shaking cavity 21 through a plurality of positioning buckles 311. Therefore, when assembling the milk bottle cover 3 and the milk shaker 2, there is no need to align the positions. Just insert the socket 31 of the milk bottle cover 3 into the milk shaking cavity 21 of the milk shaker 2 in any orientation, and the socket 31 can be meshed and driven connected with the transmission slots 42 at the bottom of the milk shaking cavity 21 of the milk shaker 2 through the positioning buckles 311, so that the assembly operation is convenient for the user to use.

[0047] Furthermore, the milk shaker 2 is fixedly connected to the rotating shaft of the motor 11 in the machine base 1, and the milk shaker 2 is driven by the motor 11 to rotate on the machine base 1. After the milk bottle 9 is placed in the accommodating cavity of the milk bottle cover 3, then insert the socket 31 of the milk bottle cover 3 into the milk shaking cavity 21 of the milk shaker 2 in any orientation, and it is meshed and driven connected with the transmission slots 42 at the bottom of the milk shaking cavity 21 of the milk shaker 2 through the positioning buckles 311, realizing the drive assembly of the milk bottle cover 3 into the milk shaker 2. And under the action of the gravity of the milk bottle 9, the milk bottle cover 3 can be kept in drive assembly connection with the milk shaker 2 during the rotation of the milk shaker 2, ensuring that the motor 11 in the machine base 1 can drive the milk bottle cover 3 to rotate through the milk shaker 2 to realize automatic milk shaking.

[0048] In one embodiment, an annular gear ring 4 is provided at the bottom of the milk shaking cavity 21, and a plurality of transmission teeth 41 are arranged at equal intervals on the annular gear ring 4. The annular gear ring 4 can be fixed at the bottom of the milk shaking cavity 21 of the milk shaker 2, or can be an integrally formed structure with the milk shaker 2. By setting the annular gear ring 4, it is convenient to arrange a plurality of transmission teeth 41 in a circular arrangement at the bottom of the milk shaking cavity 21.

[0049] In one embodiment, the annular gear ring 4 and the milk shaking cavity 21 are coaxially arranged, and a plurality of vertically extending guide ribs 24 are provided on the inner side wall of the milk shaking cavity 21. To facilitate the insertion of the socket 31 of the milk bottle sleeve 3 into the milk shaking cavity 21, generally, the size of the socket 31 is slightly smaller than that of the milk shaking cavity 21 to ensure a reasonable assembly clearance when the socket 31 is inserted into the milk shaking cavity 21. By providing the guide ribs 24, it provides guidance and limitation for the insertion of the socket 31 of the milk bottle sleeve 3 into the milk shaking cavity 21, ensuring that the positioning buckle 311 at the bottom of the socket 31 cannot be aligned with the transmission groove 42 on the annular gear ring 4 due to the assembly clearance during the insertion of the socket 31 into the milk shaking cavity 21, resulting in failure of transmission assembly.

[0050] In one embodiment, both opposite sides of the transmission tooth 41 close to the transmission groove 42 are provided as the first guiding inclined surfaces 411; both opposite sides of the positioning buckle 311 are provided as the second guiding inclined surfaces 312. Therefore, when the milk bottle sleeve 3 is inserted into the milk shaking cylinder 2, one of the second guiding inclined surfaces 312 on both sides of the lower end of the positioning buckle 311 will surely contact the first guiding inclined surface 411 of the corresponding position of the transmission groove 42. By using the cooperation of the first guiding inclined surface 411 and the second guiding inclined surface 312, the positioning buckle 311 slides along the first guiding inclined surface 411 into the transmission groove 42 at the corresponding position respectively, realizing the meshing connection of each positioning buckle 311 with the transmission groove 42 at the corresponding position.

[0051] Moreover, the top surface of the transmission tooth 41 is an arc-shaped first arc surface 413, and the lower end surface of the positioning buckle 311 is an arc-shaped second arc surface 313. When the milk bottle sleeve 3 is inserted into the milk shaking cylinder 2, when the second arc surface 313 of the positioning buckle 311 touches the first arc surface 413 of the transmission tooth 41, mutual guiding sliding occurs between the first arc surface 413 and the second arc surface 313 without jamming, guiding the second guiding inclined surface 312 of the positioning buckle 311 to the first guiding inclined surface 411 of the transmission tooth 41. Therefore, through the cooperation of the first arc surface 413 and the second arc surface 313, it is more beneficial for the positioning buckle 311 to automatically slide into the transmission groove 42 at the corresponding position, improving the reliability of the transmission assembly between the milk bottle sleeve 3 and the milk shaking cylinder 2.

[0052] The cross-section of the positioning buckle 311 is also V-shaped; the first guiding inclined surfaces 411 on both opposite sides of the transmission tooth 41 extend to the bottom of the transmission groove 42, and the cross-section of the transmission groove 42 is V-shaped. Of course, the first guiding inclined surface 411 may not extend to the bottom of the transmission groove 42, and the first guiding inclined surface 411 is only provided on the two opposite sides of the upper end of the transmission tooth 41 close to the transmission groove 42, so that the upper half of the cross-section of the transmission groove 42 is V-shaped.

[0053] A transmission hole 23 is provided at the center of the bottom of the milk shaking cavity 21. The milk shaking cylinder 2 is drivingly connected to the rotating shaft of the motor 11 through a fixing member (such as a screw or a rivet) passing through the transmission hole 23, so that the motor 11 drives the milk shaking cylinder 2 to rotate on the machine base 1.

[0054] In one embodiment, a connecting groove 12 is recessed on the upper end surface of the machine base 1. A connecting platform 22 is protruded downward at the center of the bottom of the milk shaking cylinder 2. A transmission hole 23 is provided through the connecting platform 22. The connecting platform 22 is located in the connecting groove 12, and the milk shaking cylinder 2 is in transmission connection with the rotating shaft of the motor 11 through the transmission hole 23. Through the cooperation of the connecting platform 22 and the connecting groove 12, the connecting structure for rotatably connecting the milk shaking cylinder 2 to the machine base 1 is more reliable, which is beneficial to reducing the shaking of the milk shaking cylinder 2 during rotation and reducing the risk of loosening between the milk bottle sleeve 3 and the milk shaking cylinder 2 during rotation, thereby ensuring the working reliability of the mother and baby machine.

[0055] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
