[0020] FIG. 2 is a schematic view of the milk powder solution according to an embodiment of the present invention as it revolves.

DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0022] As shown in FIG. 1, the stirring type feeding-bottle includes a base 1 and a feeding-bottle assembly 2.

[0023] The base 1 includes a base body 11 and a drive device disposed in the base body 11. In the embodiment, the drive device may be a magnetic drive device 12.

[0024] The base body 11 includes a lower casing 111 and an upper casing 112. The upper casing 112 is snapped on the lower casing 111, so that the magnetic drive device 12 is conveniently installed and disassembled. The lower casing 111 is provided with an upward protrusion 1111 at a central position. The protrusion 1111 has a holding cavity 1112 for holding a motor. A concave recessed portion is provided on a top surface of the upper casing 112. A pad 113 is disposed in the recessed portion. An upper surface of the pad 113 acts as a feeding-bottle placement position. When the pad 113 is worn, it is convenient to replace the pad 113 separately, and the cost is low.

[0025] The magnetic drive device 12 includes a motor 121, a holder 122, and a magnet 123. The motor is held in the holding cavity. The holding cavity has a positioning function on the motor 121, thereby ensuring high mounting reliability of the motor 121.

[0026] The holder 122 includes a connecting post 1220 and a supporting portion 1221 extending outward from a central portion of the connecting post 1220. The supporting portion 1221 is provided with a bearing portion 1222 symmetric with respect to the connecting post. A magnet cavity 1223 is disposed within the bearing portion. The magnet 123 is provided inside the magnet cavity 1223. The connecting post 1220 is sleeved on an output shaft of the motor. When the motor is working, the output shaft of the motor 121 drives the holder 122 to revolve, and the holder 122 in turn drives the magnet 123 to revolve. By providing the magnet cavity 1223, the magnet 123 can be fixed without any additional fixing means, which simplifies the structure. Further, the magnet 123 is symmetrically arranged to make the magnetic driving force uniform and large.

[0027] The feeding-bottle assembly 2 includes a feeding-bottle 21, a nipple subassembly 22, a flexible straw 23 and a counterweight head. In one embodiment, the counterweight head may be a magnetic bead assembly 24. The nipple subassembly 22 includes a cover and a nipple. The nipple is disposed on the feeding-bottle 21 through the cover. The flexible straw 23 is a silicone straw. An upper end of the flexible straw 23 is inserted into an interface at the bottom of the nipple. The magnetic bead assembly 24 includes a magnetic bead 241, a hardened layer wrapped around the magnetic bead 241, and a silicone body 242 wrapped around the hardened layer (not shown). An upper end of the silicone body 242 is inserted at a lower end of the flexible straw. A through hole is formed in the middle of the silicone body 242 which communicates with the flexible straw 23. A gap is formed between the magnetic bead assembly 24 and an inner bottom surface of the feeding-bottle. Silicone body is a safe and environmentally friendly material for the human body. The magnetic beads 241 are wrapped in the silicone body 242, the milk powder solution is not easily contaminated, and is safer, more hygienic and more friendly to environment, when the magnetic bead assembly is in contact with the milk powder solution. At the same time, the hardened layer can protect the magnetic beads more reliably. A convex rib 2421 is provided at the bottom of the silicone body 242, thus reducing the possibility of blockage of the silicone body. A convex ring 2422 is provided on the outer circumference of the silicone body 242 to improve the uniformity of stirring.

[0028] In this embodiment, the milk powder solution is stirred in such a way that the feeding-bottle assembly 2 is placed on the feeding-bottle placement position of the pad, the motor 121 is started, the motor 121 drives the holder 122 to revolve, the holder 122 in turn drives the magnet 123 to revolve, thereby the magnetic bead assembly 24 is driven to revolve under a magnetic field, and the flexible straw is driven to revolve by the magnetic bead assembly 24. In the present invention, the rotation of the counterweight head and the flexible straw refers to revolution. Meanwhile, since the upper end of the flexible straw 23 is inserted into the nipple and they do not revolve relative to each other, the flexible straw 23 and the magnetic bead assembly 24 rotate on their own axis in an opposite direction to the revolution of the magnetic bead assembly 24 and the flexible straw 23. The milk powder solution may revolve as the magnetic bead assembly 24 and the flexible straw 23 revolve, causing the revolving milk powder solution surface to be low in the middle and high in the periphery to form a vortex. A centripetal force of the milk powder solution near the side of the magnetic bead assembly 24 is large, so that the milk powder solution at the bottom of the feeding-bottle flows outward from the middle. When the milk powder solution flows outward, the milk powder solution in the outer layer moves outward, the milk powder solution in the upper layer is replenished from the outer layer to the middle, so that the milk powder solution in the upper layer flows from the outer side to the middle. The middle milk powder solution flows from up to down, so that the milk powder solution moves from up to down in the middle and moves from down to up in the outer layer in the axial direction. At the same time, during the rotation of the milk powder solution, the milk powder in the milk powder solution forms a cycle with spiral ascending followed by spiral descending.

[0029] According to such structure of this embodiment, when the magnetic drive device 12 is in operation, the magnetic drive device 12 drives the magnetic bead assembly 24 to revolve, and the magnetic bead assembly 24 in turn drives the flexible straw 23 to revolve, which serves to stir. The flexible straw 23 is connected to the nipple, and the portion of the flexible straw 23 connected to the nipple does not rotate with respect to the nipple. Thus, when the magnetic bead assembly 24 and the flexible straw 23 are driven to revolve by the magnetic drive device 12, the flexible straw 23 and the magnetic bead assembly 24 will rotate on their own axis in an opposite direction to the revolution of the magnetic bead assembly 24 and the flexible straw 23. Therefore, even when the magnetic bead assembly 24 and the flexible straw 24 revolve, even a water channel is generated behind the magnetic bead assembly 24 and the flexible straw 23, the milk powder solution will fill the water channel rapidly due to the rotation, making it difficult for air to enter the water channel. Thus, when milk power solution is stirred by means of the structure of the present invention, the milk powder solution will generate fewer or no bubbles, and even if a small amount of bubbles is generated, they will disappear within a short time.

[0030] When the flexible straw 23 and the magnetic bead assembly 24 revolve, the milk powder solution will follow the revolution, especially when the flexible straw 23 follows the revolution, causing the rotating milk powder solution surface to be low in the middle and high in the periphery to form a vortex. Since the lower end of the flexible straw 23 is connected to the magnetic bead assembly 24, when the flexible straw 23 and the magnetic bead assembly 24 revolve simultaneously, a centripetal force of the milk powder solution near the side of the magnetic bead assembly 24 is large, as shown in FIG. 2, so that the milk powder solution at the bottom of the feeding-bottle flows outward from the middle. When the liquid flows outward, the milk powder solution in the outer layer moves outward, and the milk powder solution in the upper layer is replenished from the outer layer to the middle, so that the milk powder solution flows from the outer side in the upper layer to the middle. The middle milk powder solution flows from up to down, so that the milk powder solution moves from up to down in the middle and moves from down to up in the outer layer. At the same time, during the rotation of the milk powder solution, the milk powder in the milk powder solution forms a cycle with spiral ascending followed by spiral descending. In this way, the mixing of the milk powder solution is more uniform.

[0031] In the present invention, the flexible straw and the magnetic bead assembly 24 serve to stir and at the same time serve as a straw for feeding, thus facilitating feeding.
