[0029] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0030] like Figure 1 and Figure 2As shown, the present invention discloses a mother-infant machine, comprising a machine base 1 with a built-in motor 11 and a bottle sleeve 3, the bottle sleeve 3 comprising a sleeve seat 31 and a sleeve body 32 arranged on the sleeve bottom 31, the sleeve bottom 31 and the sleeve body 32 together enclose a receiving cavity for placing a bottle; a transmission mechanism is provided between the machine base 1 and the sleeve seat 31 of the bottle sleeve 3, the bottle sleeve 3 is assembled on the machine base 1 through the transmission mechanism, so that the motor 11 drives the bottle sleeve 3 to rotate, and the bottle placed in the receiving cavity of the bottle sleeve 3 is provided with a rotation and shaking, so as to promote the uniform mixing of milk powder and water in the bottle.

[0031] Further integration Figure 2-Figure 6 The transmission mechanism of the maternal and infant machine specifically includes: a rotating sleeve 2 arranged on the machine base 1 and connected to the motor 11 in the machine base 1 for rotation (or transmission connection), the rotating sleeve 2 having an assembly cavity 21 with an opening facing upward; a plurality of transmission teeth 41 arranged at the bottom of the assembly cavity 21, the plurality of transmission teeth 41 are evenly spaced and distributed on the first circumference of the radius R, there is a transmission groove 42 between any two adjacent transmission teeth 41, any two adjacent transmission grooves 42 have an equal groove distance D on the first circumference, and a first guide inclined surface 411 is provided on the side of each transmission tooth 41 close to the transmission groove 42; a plurality of positioning buckles 311 are arranged at the bottom of the sleeve 31 of the bottle sleeve 3, the plurality of positioning buckles 311 are spaced and distributed on the second circumference of the radius R, the spacing between two adjacent positioning buckles 311 on the second circumference is N times the groove distance D (N is a natural number), and the lower end of each positioning buckle 311 has a second guide inclined surface 312 matched with the first guide inclined surface 411.

[0032] This solution provides a positioning buckle 311 and a transmission tooth 41 and a transmission groove 42 for transmission cooperation. The positioning buckle can be positioned in the transmission groove so that the bottle sleeve 3 is driven to rotate. Compared with the technical solution of the prior art in which the bottle is directly placed on the rotating sleeve, this transmission mechanism has a good positioning effect, which makes it difficult for the bottle sleeve to slide relative to the rotating sleeve, thereby ensuring the milk shaking effect and stability.

[0033] The size of the first circumference formed by the multiple transmission teeth 41 at the bottom of the assembly cavity 21 is consistent with the size of the second circumference formed by the multiple positioning buckles 311, ensuring that when the sleeve seat 31 of the bottle sleeve 3 is inserted into the assembly cavity 21 of the rotating sleeve 2, the second guide slope 312 of each positioning buckle 311 can contact the first guide slope 411 of the transmission tooth 41 at the corresponding position. At the same time, since the spacing between two adjacent positioning buckles 311 on the second circumference is N times the groove distance D (N is a natural number), each positioning buckle 311 can be engaged with the transmission groove 42 at its corresponding position at the same time, which provides conditions for the bottle sleeve 3 to be inserted into the assembly cavity 21 of the rotating sleeve 2 in any orientation without alignment, and to realize the transmission assembly with the rotating sleeve 2 by using the meshing connection between the positioning buckle 311 and the transmission groove 42.

[0034] Therefore, the present invention provides a bottle sleeve 3 that can be quickly positioned when assembled with the rotating sleeve 2, and does not need special alignment when inserted. The transmission assembly connection can be achieved at any angle, simplifying the assembly for easy use. At the same time, the present invention provides multiple positioning buckles 311, and utilizes multiple positioning buckles 311 to engage and connect with the transmission teeth 41 at corresponding positions to achieve multi-point transmission, thereby ensuring the reliability of the transmission assembly connection between the bottle sleeve 3 and the rotating sleeve 2, ensuring stable transmission so that the rotating sleeve 2 can drive the bottle sleeve 3 to rotate stably, which is beneficial to improving the user experience of the mother and baby machine.

[0035] The base 1 drives the bottle sleeve 3 to rotate through the aforementioned transmission mechanism, providing automatic milk shaking for the bottle placed in the accommodating cavity, replacing manual milk shaking to make the milk powder brew and mix evenly. When in use, the sleeve 31 of the bottle sleeve 3 is inserted into the assembly cavity 21 of the rotating sleeve 2. Since the spacing between two adjacent positioning buckles 311 on the second circumference is N times the groove distance D, it can be ensured that the second guide bevel 312 of each positioning buckle 311 can definitely contact the first guide bevel 411 of the transmission tooth 41 at the corresponding position. By using the first guide bevel 411 and the second guide bevel 312 to cooperate, each positioning buckle 311 slides into a transmission groove 42 at the corresponding position, so that the bottle sleeve 3 is connected to the transmission groove 42 at the bottom of the assembly cavity 21 through multiple positioning buckles 311. Therefore, there is no need to align the bottle sleeve 3 and the rotating sleeve 2 when assembling them. It is only necessary to insert the sleeve seat 31 of the bottle sleeve 3 into the assembly cavity 21 of the rotating sleeve 2 in any orientation, so that the sleeve seat 31 can be engaged and connected with the transmission groove 42 at the bottom of the assembly cavity 21 of the rotating sleeve 2 through the positioning buckle 311, so that the assembly operation is convenient for users to use.

[0036] Furthermore, the rotating sleeve 2 is fixedly connected to the rotating shaft of the motor 11 in the base 1, and the rotating sleeve 2 is driven by the motor 11 to rotate on the base 1. After the milk bottle 9 is placed in the accommodating cavity of the milk bottle sleeve 3, the sleeve seat 31 of the milk bottle sleeve 3 is inserted into the assembly cavity 21 of the rotating sleeve 2 in any direction, and the positioning buckle 311 is engaged with the transmission groove 42 at the bottom of the assembly cavity 21 of the rotating sleeve 2 to achieve the milk bottle sleeve 3 being assembled into the rotating sleeve 2. Moreover, under the gravity of the milk bottle 9, the milk bottle sleeve 3 can be kept connected with the rotating sleeve 2 from the transmission assembly during the rotation of the rotating sleeve 2, ensuring that the motor 11 in the base 1 can drive the milk bottle sleeve 3 to rotate through the rotating sleeve 2 to achieve automatic milk shaking.

[0037] In one embodiment, an annular gear ring 4 is provided at the bottom of the assembly cavity 21, and a plurality of transmission teeth 41 are arranged evenly at intervals on the annular gear ring 4. The annular gear ring 4 can be fixed to the bottom of the assembly cavity 21 of the rotating sleeve 2, or can be an integrally formed structure with the rotating sleeve 2. By providing the annular gear ring 4, it is convenient to arrange a plurality of transmission teeth 41 in a circular shape at the bottom of the assembly cavity 21.

[0038] In one embodiment, the annular gear ring 4 is coaxially arranged with the assembly cavity 21, and a plurality of vertically extending guide ribs 24 are arranged on the inner side wall of the assembly cavity 21. In order to facilitate the insertion of the sleeve 31 of the bottle sleeve 3 into the assembly cavity 21, generally speaking, the size of the sleeve 31 is slightly smaller than the size of the assembly cavity 21, ensuring that there is a reasonable assembly gap when the sleeve 31 is inserted into the assembly cavity 21. By providing the guide ribs 24, the sleeve 31 of the bottle sleeve 3 is provided with guidance and position limiting when it is inserted into the assembly cavity 21, ensuring that the sleeve 31 of the bottle sleeve 3 is inserted into the assembly cavity 21. The assembly gap will not cause the positioning buckle 311 at the bottom of the sleeve 31 to be unable to align with the transmission groove 42 on the annular gear ring 4 and fail to transmit and assemble during the insertion of the sleeve 31 into the assembly cavity 21.

[0039] In one embodiment, the two opposite side surfaces of the transmission tooth 41 near the transmission groove 42 are both set as the first guiding inclined surface 411; the two opposite side surfaces of the positioning buckle 311 are both set as the second guiding inclined surface 312. Therefore, when the bottle sleeve 3 is inserted into the rotating sleeve 2, the second guiding inclined surface 312 of one of the two side surfaces at the lower end of the positioning buckle 311 will definitely contact the first guiding inclined surface 411 of the transmission groove 42 at the corresponding position, and the first guiding inclined surface 411 cooperates with the second guiding inclined surface 312 to allow the positioning buckle 311 to slide into the transmission groove 42 at the corresponding position along the first guiding inclined surface 411, so that each positioning buckle 311 is respectively engaged and connected with the transmission groove 42 at the corresponding position.

[0040] Furthermore, the top end 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 bottle sleeve 3 is inserted into the rotating sleeve 2, when the second arc surface 313 of the positioning buckle 311 touches the first arc surface 413 of the transmission tooth 41, the first arc surface 413 and the second arc surface 313 are mutually guided and slid without being stuck, and the second guiding inclined surface 312 of the positioning buckle 311 is guided to the first guiding inclined surface 411 of the transmission tooth 41. Therefore, the first arc surface 413 cooperates with the second arc surface 313 to make the positioning buckle 311 automatically slide into the transmission groove 42 at the corresponding position, thereby improving the reliability of the transmission assembly of the bottle sleeve 3 and the rotating sleeve 2.

[0041] The cross section of the positioning buckle 311 is also V-shaped; the first guide inclined surfaces 411 on the two 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, such as Figure 5 , Figure 6 Of course, the first guiding inclined surface 411 may not extend to the bottom of the transmission groove 42. The first guiding inclined surface 411 is only provided on the two opposite sides of the transmission groove 42 at the end of the transmission tooth 41, so that the cross section of the upper half of the transmission groove 42 is V-shaped, as shown in FIG. Figure 7 shown.

[0042] like Figure 8In the illustrated embodiment, the first guiding bevel 411 is arranged on the side of the transmission tooth 41 facing the rotation direction of the rotating sleeve 2, and the side of the transmission tooth 41 facing away from the first guiding bevel 411 is a vertical first vertical blocking surface 414, that is, the first vertical blocking surface 414 is located on the side of the transmission tooth 41 facing away from the rotation direction of the rotating sleeve 2; the second guiding bevel 312 is arranged on the side of the lower end of the positioning buckle 311 facing the first guiding bevel 411, and the side of the second guiding bevel 312 facing away from the first guiding bevel 411 is correspondingly provided with a vertical second vertical blocking surface 314. When the bottle sleeve 3 is inserted into the rotating sleeve 2, the first arc surface 413 and the second arc surface 313 are guided and cooperated to allow the bottle sleeve 3 to rotate at a small angle until the second guide inclined surface 312 of the positioning buckle 311 contacts the first guide inclined surface 411 of the transmission tooth 41, so that the positioning buckle 311 slides into the transmission groove 42 at the corresponding position guided by the second guide inclined surface 312 and the first guide inclined surface 411, thereby realizing the meshing transmission assembly of the bottle sleeve 3 and the rotating sleeve 2.

[0043] When the motor 11 drives the rotating sleeve 2 to rotate, the second guiding bevel 312 contacts the side of the first guiding bevel 411. Since the first vertical blocking surface 414 is located on the side of the transmission tooth 41 facing away from the rotation direction of the rotating sleeve 2, no guiding movement will occur between the first vertical blocking surface 414 and the second guiding bevel 312, thereby preventing the bottle sleeve 2 from moving in the direction of the first vertical blocking surface 414 out of the transmission groove 42 during the rotation process, ensuring that the bottle sleeve 2 remains meshed and connected with the rotating sleeve 2 under the action of gravity, thereby helping to further improve the reliability of the transmission assembly of the bottle sleeve 3 and the rotating sleeve 2.

[0044] Further integration Figure 1 , Figure 4-Figure 6 A transmission hole 23 is provided at the bottom center of the assembly cavity 21 , and a fixing member (such as a screw or a rivet) passes through the transmission hole 23 to connect the rotating sleeve 2 with the rotating shaft of the motor 11 , so that the motor 11 drives the rotating sleeve 2 to rotate on the base 1 .

[0045] In one embodiment, the upper end surface of the base 1 is provided with a concave connection groove 12, the bottom center of the rotating sleeve 2 is provided with a convex connection platform 22, the transmission hole 23 is provided through the connection platform 22, the connection platform 22 is located in the connection groove 12, and the rotating sleeve 2 is connected to the rotating shaft of the motor 11 by transmission through the transmission hole 23. Through the cooperation of the connection platform 22 and the connection groove 12, the connection structure of the rotating sleeve 2 rotatably connected to the base 1 is more reliable, which is conducive to reducing the shaking of the rotating sleeve 2 during the rotation process, reducing the risk of the bottle sleeve 3 and the rotating sleeve 2 being loosened during the rotation process, and thus ensuring the working reliability of the mother-infant machine.

[0046] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
