Description

Technical Field

[0001] This utility model relates to the technical field of baby products, specifically to a milk warmer and shaker with an eccentric motion structure. Background Technology

[0002] To simplify infant feeding, many parents choose formula as an alternative. However, formula often doesn't dissolve quickly in water, requiring prolonged manual shaking of the bottle to achieve complete mixing—a rather tedious process. Most bottle shakers on the market currently use either a central or eccentric rotation method to agitate the bottle, but these designs typically lack mechanisms to stabilize the bottle. Therefore, there is still room for improvement in bottle shakers. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0027] See Figures 1-11 A milk warmer and shaker with an eccentric motion structure includes a body 1, a positioning component 2 and a driver 3 disposed in the body 1, wherein the positioning component 2 is used to position the container and is eccentrically connected to the drive shaft of the driver 3. An eccentric motion component 4 is provided between the positioning component 2 and the inner side of the body 1 to assist the positioning component 2 in making eccentric movements. During the operation of the positioning component 2 driven by the driver 3, the eccentric motion component 4 acts on the positioning component 2 to make the positioning component 2 run smoothly.

[0028] By using the positioning component 2 to position the container and connecting it to the drive shaft of the driver 3 via an eccentric transmission, the bottle can achieve eccentric movement within the shaker. Meanwhile, the eccentric movement component 4, which is provided between the positioning component 2 and the inner side of the body 1, can act on the positioning component 2 during the operation of the positioning component 2 driven by the driver 3, providing assistance for the eccentric movement of the positioning component 2.

[0029] The eccentric motion assembly 4 is provided with an upper connecting shaft 6.1 that cooperates with the positioning member 2 and a lower connecting shaft 6.4 that cooperates with the interior of the body 1. The upper connecting shaft 6.1 and the lower connecting shaft 6.4 are eccentrically arranged and their axes are not on the same axis.

[0030] The eccentric motion assembly 4 includes a first bearing 5 acting on the positioning member 2, and the first bearing 5 acting on the outer side of the positioning member 2. The positioning member 2 has a mounting groove 2.1 on its outer side, and the first bearing 5 is limited within the mounting groove 2.1; The eccentric motion assembly 4 also includes a connector 6 connected to the first bearing 5, and the connector 6 is provided with a buckle 6.2 fixed on the inner side of the body 1; The upper connecting shaft 6.1 and the lower connecting shaft 6.4 are arranged vertically on the connector 6. The first bearing 5 is connected to the upper connecting shaft 6.1. During the eccentric movement of the positioning member 2, the connector 6 rotates within the machine body 1 through the lower connecting shaft 6.4. The buckle 6.2 is arranged on the outside of the lower connecting shaft 6.4.

[0031] The first bearing 5 and the positioning component 2 are connected by the connector 6. The connector 6 is also secured to the inside of the machine body 1 by the latch 6.2, ensuring the stability of the eccentric motion component 4 during the operation of the milk shaker and preventing loosening or displacement due to vibration or other factors. This stable connection structure helps ensure that the first bearing 5 can act on the positioning component 2 during its operation, providing reliable assistance for the eccentric motion of the positioning component 2 and further enhancing its smooth operation. During the eccentric motion of the positioning component 2, the latch 6.2 is engaged with the inside of the machine body 1 while rotating along with the connector 6.

[0032] The first bearing 5 can be located on the outside or bottom of the positioning member 2. During the operation of the positioning member 2, the first bearing 5 acts on the positioning member 2. The rotational design of the first bearing 5 further reduces the frictional resistance during the movement of the positioning member 2, ensuring smooth operation and preventing jamming. The mounting groove 2.1 at the bottom of the positioning member 2 is used to accommodate the first bearing 5. When the positioning member 2 performs eccentric circumferential movement, the first bearing 5 is confined within the mounting groove 2.1. This structure not only prevents the first bearing 5 from detaching from the positioning member 2 during movement but also makes the fit between the first bearing 5 and the positioning member 2 more precise, thereby better assisting the positioning member 2 in operating smoothly.

[0033] The body 1 is provided with a fixing member 7, which is fixed inside the body 1. The fixing member 7 is provided with an assembly groove 7.1 for installing the connector 6. The buckle 6.2 of the connector 6 is fastened to the outside of the assembly groove 7.1 to prevent the connector 6 from detaching from the fixing member 7.

[0034] There is no structure on the outside of the assembly groove 7.1 that prevents the buckle 6.2 from rotating; the buckle 6.2 can rotate along the outside of the assembly groove 7.1.

[0035] The fastener 7 provides a precise mounting and positioning structure for the connector 6 in the eccentric motion assembly 4. The mounting slot 7.1 accurately defines the installation position of the connector 6, ensuring that the connector 6 maintains a relatively fixed positional relationship with the body 1 after installation. This prevents the connector 6 from shifting position during the operation of the milk shaker and from easily detaching from the fastener 7. The snap-fit ​​design between the buckle 6.2 and the outer side of the mounting groove 7.1 further enhances the stability of the connector 6 during installation. When the milk shaker is running, certain vibrations and forces are generated inside, and the snap-fit ​​structure of the buckle 6.2 can effectively resist these external forces, preventing the connector 6 from detaching from the fixing part 7, thereby ensuring that the first bearing 5 connected to the connector 6 can stably act on the positioning part 2.

[0036] The connecting member 6 is provided with an upper connecting shaft 6.1 that connects to the first bearing 5. The first bearing 5 is sleeved on the outside of the upper connecting shaft 6.1. The outer side of the upper connecting shaft 6.1 is provided with a protrusion 6.3. The protrusion 6.3 has an arc surface that forms point contact, line contact, or surface contact with the shaft hole of the first bearing 5. This design makes the connection between the first bearing 5 and the upper connecting shaft 6.1 tighter and more flexible. The arc surface design can reduce the friction between the first bearing 5 and the upper connecting shaft 6.1, making the rotation of the first bearing 5 on the upper connecting shaft 6.1 smoother. It also makes the first bearing 5 play a role in preventing jamming when the positioning member 2 is running, thereby better assisting the positioning member 2 in eccentric movement. The protrusion 6.3 can compensate for the rotational fit clearance between the connecting member 6 and the first bearing 5.

[0037] An eccentric transmission assembly 20 is provided between the positioning member 2 and the drive shaft of the driver 3. The eccentric transmission assembly 20 includes a first connecting shaft 10.1 connected to the drive shaft of the driver 3 and a second connecting shaft 10.2 connected to the positioning member 2. The first connecting shaft 10.1 and the drive shaft of the driver 3 are coaxially arranged, and the positioning member 2 and the second connecting shaft 10.2 are coaxially arranged. The first connecting shaft 10.1 and the second connecting shaft 10.2 are eccentrically arranged, and their axes are not on the same axis.

[0038] The eccentric transmission assembly 20 includes a first transmission member 8 fixedly connected to the positioning member 2, and a second bearing 9 sleeved on the second connecting shaft member 10.2.

[0039] Through the cooperation of the first transmission component 8 and the second bearing 9, the power of the driver 3 can be transmitted to the positioning component 2 more stably and efficiently, enabling the positioning component 2 to perform eccentric motion more stably. The second bearing 9 has good rotational performance and friction reduction effect, which can reduce the friction between the first transmission component 8 and the eccentric rotating shaft, and play a role in preventing jamming.

[0040] The eccentric transmission assembly 20 includes a second transmission member 10 connected to the drive shaft of the driver 3, and a second connecting shaft 10.2 and a first connecting shaft 10.1 are arranged vertically on the second transmission member 10.

[0041] The eccentric transmission assembly 20 includes a bracket 11 for fixing the second bearing 9, and the bracket 11 is fixed inside the body 1; The bracket 11 includes a positioning platform 11.1 with a fixed groove and a connecting arm 11.2. The second bearing 9 is installed in the fixed groove of the positioning platform 11.1. The connecting arm 11.2 is fixedly connected to the inner side of the body 1. The first transmission component 8, the positioning component 2 and the positioning platform 11.1 of the bracket 11 are fixedly connected. A flexible connection structure is provided between the positioning platform 11.1 and the connecting arm 11.2. During the eccentric movement of the positioning platform 11.1 following the positioning component 2, the flexible connection structure deforms during the eccentric movement of the positioning component 2, and the positioning platform 11.1 swings on the connecting arm 11.2 through the flexible connection structure. The flexible connection structure includes a first flexible cantilever 11.3 and a second flexible cantilever 11.4 disposed on the outside of the positioning platform 11.1. Both the first flexible cantilever 11.3 and the second flexible cantilever 11.4 are suspended inside the body 1. Both the first flexible cantilever 11.3 and the second flexible cantilever 11.4 include flexible connecting ribs that are spaced apart from each other. One end of the second flexible cantilever 11.4 is connected to the connecting arm 11.2, and the other end of the second flexible cantilever 11.4 is connected to the first flexible cantilever 11.3 by a connecting block 11.6. An extension arm 11.5 is provided between the first flexible cantilever 11.3 and the positioning platform 11.1. The support 11 is made of wear-resistant and fold-resistant PP material.

[0042] The flexible cantilever makes the positioning component 2 more stable and regular in its cushioning. The bracket 11 has a second bearing 9 to prevent the positioning component 2 (the bottle compartment for positioning bottles and other containers) from rotating, as rotation would affect the milk shaking effect. Without the second bearing 9 and the flexible cantilever, the positioning component 2 would be directly fixed to the first transmission component 8 and the second transmission component 10 (eccentric block), causing the positioning component 2 to rotate around the motor shaft, affecting the milk shaking effect.

[0043] The body 1 is provided with a fixing member 7 for installing the eccentric motion component 4. One end of the fixing member 7 is provided with a wind guide cover 12, and the bottom of the fixing member 7 is provided with an avoidance through hole 7.2 corresponding to the eccentric transmission connection between the driver 3 and the positioning component 2. The air guide shroud 12 is provided with a ventilation duct. One end of the ventilation duct is connected to the inner cavity of the fixing member 7, and the other end of the ventilation duct is connected to the fan 13. The ventilation duct is connected to the air outlet of the fan 13. The positioning element 2 is located in the inner cavity of the fixing element 7. The positioning element 2 is provided with a plurality of circumferentially spaced air inlets 2.2. A diverting block 14 is provided on the air outlet end of the ventilation duct or the air inlet end of the inner cavity of the fixing element 7. A heater 15 is provided in the ventilation duct. The air outlet end of the ventilation duct and the inner cavity of the fixing element 7 are connected by the diverting block 14 to form a first air duct 16 and a second air duct 17. A portion of the gas output by the fan 13 enters the positioning element 2 through the first air duct 16 and the first corresponding air inlet 2.2. Another portion of the gas output by the fan 13 enters the positioning element 2 through the second air duct 17 and the second corresponding air inlet 2.2. The milk warming function is integrated into the bottle shaker. The gas output from the fan 13 is heated by the heater 15 and then flows through the diverter 14 from the first air duct 16 and the second air duct 17, entering the positioning component 2 through the air inlet 2.2, thus achieving the milk warming effect. By rationally designing the ventilation ducts, diverter 14, and air inlet 2.2, the heating gas can be evenly distributed into the positioning component 2, resulting in more uniform heating of the bottle.

[0044] The eccentric motion component 4 is provided in three or more parts, and the three or more eccentric motion components 4 are arranged at circumferential intervals at the bottom of the positioning component 2; The body 1 includes a base 18 and a housing 19 fixed on the base 18. The housing 19 has an clearance opening corresponding to the positioning member 2, and the driver 3 is fixed on the internal cavity of the base 18.

[0045] In this embodiment, the first transmission component 8, the positioning component 2, and the positioning platform 11.1 of the bracket 11 are all provided with mounting holes for inserting screws.

[0046] In this embodiment, the driver 3 is a motor, which is fixed on the motor mounting position of the base 18. The base 18 is provided with a heat dissipation port corresponding to the motor.

[0047] In this embodiment, the base 18 and the housing 19 are also fixedly connected by a connecting column and a positioning slot.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
