The speed change member 222, the connection member 23 and the anti-slipping member 24 are arranged in the box body 221, which improves the connectivity and integrity of the speed change member 222, the connection member 23 and the anti-slipping member 24, and improves the integrity of the head 100.

One end of the stirring component 6 is inserted into the connecting hole 234, so that the stirring component 6 is firmly connected to the second section 233.

[0043] Specifically, the flange section 232 is cylindrical, the cross-sectional area of ​​the flange section 232 is larger than the cross-sectional area of ​​the through hole 241, the lower surface of the flange section 232 contacts the upper surface of the anti-slip member 24, and the flange section 232 limits the first section 231, so that the first section 231 is not easy to penetrate into the through hole 241. The size of the flange section 232 along the length direction of the connecting member 23 is smaller than the size of the first section 231 along the length direction of the connecting member 23.

[0044] Specifically, the second section 233 is also cylindrical, and the second section 233 is adapted to the through hole 241. The outer circumference of the second section 233 contacts the inner circumference of the through hole 241, so that the second section 233 is firmly installed in the through hole 241. The size of the second section 233 along the length direction of the connecting member 23 is larger than the size of the through hole 241 along the axial direction of the anti-slip member 24, so that the second section 233 is not easy to fall out of the through hole 241, further improving the stability of the second section 233 installed in the through hole 241. The size of the second section 233 along the length direction of the connecting member 23 is larger than the size of the flange section 232 along the length direction of the connecting member 23, so that the structure of the connecting member 23 is simple, cost-saving, and easy to manufacture.

[0045] Specifically, there is a gap of 0.1mm to 0.5mm between the lower surface of the anti-slip part 24 and the surface of the stirring component 6 adjacent to the anti-slip part 24, so that the stirring component 6 can make a slight movement in the gap.

The arrangement of the first flat surface 2311 and the second flat surface 2313 makes it difficult for the first section 231 to rotate relative to the speed change component 222 when the speed change component 222 rotates. The arrangement of the first curved surface 2312 and the second curved surface 2314 reduces the friction between the first section 231 and the speed change component 222, thereby reducing the wear between the first section 231 and the speed change component 222, and ensuring the service life of the connecting member 23 and the speed change component 222.

The second section 233 is threadedly connected to the stirring assembly 6, so that the connection member 23 is firmly connected to the stirring assembly 6, and the spiral direction of the connection hole 234 is opposite to the rotation direction of the motor 21. When the motor 21 drives the connection member 23 to drive the stirring assembly 6 to rotate, the rotation direction of the connection member 23 is opposite to the rotation direction of the stirring assembly 6, so that the connection member 23 is more firmly connected to the stirring assembly 6.

The central gear 2223 is arranged between the three planetary gears 2224 and meshes with the three planetary gears 2224. The motor 21 drives the central gear 2223 to rotate to drive the planetary gears 2224 to rotate. The planetary gears are meshed with a circle of teeth on the inner circumference of the lower case 2212 and can rotate relative to the case 221, so that the speed change component 222 also rotates relative to the case 221, thereby allowing the connecting piece 23 that cooperates with the speed change component 222 to also rotate relative to the case 221.

[0055] By setting the above-mentioned speed change component 222, the structure of the speed change component 22 is simple, and the matching mode of the first planetary carrier 2221, the second planetary carrier 2222, the central gear 2223 and the planetary gear 2224 is simple and highly matched. In addition, the setting of the speed change component 222 changes the rotation speed of the stirring component 6, which can improve the user's operating experience. The inner circumference of the housing 221 meshes with the planetary gear 2224, which improves the matching degree and integrity of the speed change component 222 and the housing 221.

[0056] Optionally, one end of the connecting member 23 is integrally formed with the second planet carrier 2222 , thereby improving the connection strength between the connecting member 23 and the second planet carrier 2222 .

[0057] Alternatively, if Figure 8 As shown, the box body 221 includes a bottom wall 22121, a peripheral wall 22122 and a flange wall 22123, the bottom wall 22121 is arranged on the outer peripheral edge of the bottom of the peripheral wall 22122, the flange wall 22123 extends outward from the outer peripheral edge of the top of the peripheral wall 22122, and the inner bottom surface of the cover body 1 is provided with a second annular protrusion 32, and the head 100 of the supplementary food machine 200 also includes a first sealing ring 4, which is arranged between the second annular protrusion 32 and the flange wall 22123.

[0058] Specifically, the lower box body 2212 includes a bottom wall 22121, a peripheral wall 22122 and a flange wall 22123. The lower box body 2212 has a simple structure, is easy to manufacture, and saves costs. Moreover, by fitting the first sealing ring 4 between the second annular protrusion 32 and the flange wall 22123, it is possible to prevent external water vapor from entering the accommodating chamber 13, avoid water vapor from contacting the motor 21, the box body 221 and other components in the accommodating chamber 13, protect the motor 21, the box body 221 and other components from being easily corroded, and extend the service life. Moreover, the second annular protrusion 32 can also limit the installation of the box body 221, ensuring that the box body 221 is firmly installed in the accommodating chamber 13.

[0059] Specifically, the lower box body 2212 further includes a cofferdam wall 22124 , which extends upward from the outer circumference of the flange wall 22123 , and the inner circumference of the cofferdam wall 22124 is provided with teeth meshing with the planetary gear 2224 .

[0060] Alternatively, if Figure 8 As shown, the flange wall 22123 includes a first straight section 221231, an inclined section 221232 and a second straight section 221233 connected in sequence, one end of the first straight section 221231 is connected to the peripheral wall 22122, the inclined section 221232 is arranged to be inclined outward in an upward direction from the other end of the first straight section 221231, and the first sealing ring 4 is arranged between the second annular protrusion 32 and the second straight section 221233.

[0061] Specifically, the inclined section 221232 is arranged to be inclined outward from the other end of the first straight section 221231 in an upward direction, so that the cross-sectional area of ​​the inclined section 221232 adjacent to the first straight section 221231 is smaller than the cross-sectional area of ​​the inclined section 221232 adjacent to the second straight section 221233. When the box body 221 is assembled in the accommodating cavity 13, the inclined section 221232 can play a guiding role, so that the box body 221 is easily installed in the second annular protrusion 32. The first sealing ring 4 is arranged between the second annular protrusion 32 and the second straight section 221233, which can effectively prevent water vapor from entering the accommodating cavity 13 from the gap between the second annular protrusion 32 and the second straight section 221233. Moreover, the arrangement of the first sealing ring 4 also increases the friction between the second annular protrusion 32 and the second straight section 221233, so that the box body 221 is installed more firmly in the second annular protrusion 32.

[0062] like Figure 1 and Figure 6 As shown, the baby food machine 200 of the embodiment of the utility model comprises a cup body 5, a machine head 100 and a stirring assembly 6.

[0063] The baby food machine of the embodiment of the utility model drives the stirring component 6 to stir in the cup body 5 through the machine head 100, which can reduce the longitudinal swing amplitude of the stirring component 6, so that the stirring component 6 is more stable when stirring in the cup body 5 and is not easy to collide with the cup body 5, thereby ensuring the service life of the baby food machine 200 and improving the reliability of the baby food machine 200.

[0064] Specifically, Figure 2 As shown, the baby food machine further includes a third sealing ring 8 , which is disposed on the lower cover body 12 and is arranged in a circle around the circumference of the lower cover body 12 to improve the sealing between the machine head 100 and the cup body 5 .

[0065] Alternatively, if Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the stirring assembly 6 includes a coupler 61 and a knife assembly 62. The top of the coupler 61 extends into the accommodating cavity 13 and is connected to the other end of the connecting member 23. In the projection plane orthogonal to the length direction of the connecting member 23, the projection of the coupler 61 and the projection of the anti-slip member 24 at least partially overlap. A mating portion is provided at the bottom of the coupler 61, and a part of the knife assembly 62 is mated in the mating portion.

[0066] Specifically, the coupler 61 includes a base 611 and an extension portion 612 provided on the base 611. An external thread is provided on the outer peripheral surface of the extension portion 612. The external thread on the extension portion 612 cooperates with the thread of the connecting hole 234 on the second section 233, so that the coupler 61 is connected to the connecting member 23. A matching groove 6111 that cooperates with the knife assembly 62 is provided at the bottom of the base 611. One end of the knife assembly 62 is connected to the base 611 through the matching groove 6111, and the other end of the knife assembly 62 is located in the cup body 5.

[0067] Specifically, the anti-slip component 24 serves to limit the coupler 61, thereby reducing the moving distance of the coupler 61 in the length direction of the connecting component 23, thereby reducing the moving distance of the knife assembly 62 in the length direction of the connecting component 23, and improving the stability of the knife assembly 62 when stirring in the cup body 5.

[0068] like Figure 7 As shown, the baby food machine 200 also includes a second sealing ring 7, and the inner bottom surface of the cover body 1 is provided with a third annular protrusion 33, and the second sealing ring 7 abuts against the outer peripheral surface of the coupler 61, the inner peripheral surface of the third annular protrusion 33 and the outer bottom surface of the box body 221.

[0069] Specifically, the third annular protrusion 33 is located on the inner bottom surface of the lower cover 12 and inside the second annular protrusion 32. The third annular protrusion 33 is provided to limit the coupler 61 in a plane orthogonal to the extension direction of the anti-slip member 24, so as to further improve the stability of the knife assembly 62 when stirring in the cup body 5. The second sealing ring 7 is provided to prevent the water vapor in the cup body 5 from entering the machine head 100 and the lubricating oil in the machine head 100 from overflowing, thereby ensuring the sealing of the machine head 100 and extending the service life of the machine head 100.
