Description

Technical Field

[0002] A baby food feeder is a tool used to feed babies complementary foods. It contains complementary foods that spill out as the baby sucks and bites, thus achieving the feeding effect. As the baby sucks, the amount of complementary food in the feeder gradually decreases, eventually leaving some food residue.

[0003] Traditional baby food feeders solve the problem of food residue by manually pushing the feeder, requiring mothers to assist in pushing it when feeding their babies. This cumbersome operation can be inconvenient for mothers. Furthermore, relying on manual pushing to remove food residue results in extremely complex feeders that are difficult to assemble and clean, and it's impossible to guarantee that all components are made of food-grade materials, posing a risk of accidental ingestion by the baby.

[0027] 3. The snap-fit ​​end and the free end of the elastic element of the present invention are connected by a toothed sidewall, which enables deformation of the toothed sidewall along the axis of the elastic element; the outer sidewall surface of the free end of the elastic element is a corrugated surface, which can reduce the resistance encountered by the elastic element when it elongates and ensure the collection effect of the supplementary food.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] In the description of this invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and do not require that this invention must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0043] The terms “connected” and “linked” used in this invention should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; they can refer to direct connections or indirect connections through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0044] like Figure 1 , Figure 3 and Figure 8 As shown, the present invention provides an automatic feeding device, which mainly includes a snap-fit ​​body 3, an elastic element 16 and a strainer 4; the inner side of the snap-fit ​​body 3 is snapped with one end of the elastic element 16, the outer side of the snap-fit ​​body 3 is snapped with the strainer 4, the other end of the elastic element 16 extends into the strainer 4, the strainer 4 has a feeding cavity inside and an overflow hole 5 on the outer wall.

[0045] Specifically, in use, the automatic feeding utensil of this invention involves installing the elastic element 16 onto the snap-fit ​​body 3, filling the feeding cavity inside the strainer 4 with supplementary food, and then installing the snap-fit ​​body 3 onto the strainer 4. Since the feeding cavity is full of supplementary food, the elastic element 16 is in a compressed state and stores energy. When the baby sucks and bites the strainer 4, the supplementary food in the strainer 4 flows out through the overflow hole 5 and is consumed by the baby. As the supplementary food flows out, the amount of food in the feeding cavity gradually decreases, and the compressed elastic element 16 gradually extends downwards, squeezing the internal space of the feeding cavity. This reduces the internal space of the feeding cavity, allowing any remaining supplementary food to be collected and concentrated at the overflow hole 5 for the baby to eat, making it easier for the baby to eat and preventing food residue. This invention has a simple structure, is easy to operate, easy to clean, and convenient to assemble and use. It automatically pushes and collects supplementary food when the baby uses it, eliminating the need for the mother to manually push it, thus bringing convenience to the mother during feeding. Furthermore, this invention achieves automatic collection of complementary foods without the need for a complex propulsion structure, making the foods easy to eat and providing a better experience for the baby. With fewer parts and a strong overall design, this invention reduces the risk of accidental ingestion by the baby, ensuring safety while enhancing the user experience. It is characterized by its simple structure, convenient operation, safe use, and excellent user experience.

[0046] As an optional implementation, the elastic element 16 of the present invention can be a column made of liquid silicone; or a metal spring can be used, with a liquid silicone layer coated on the outer wall of the metal spring by an encapsulation process and a liquid silicone bottom surface formed on the bottom of the metal spring by an encapsulation process.

[0047] As an improvement to the present invention, such as Figures 1 to 10 As shown, the present invention also provides the following improvements:

[0048] like Figure 1 , Figure 3 and Figure 8 As shown, an automatic feeding aid mainly includes a snap-fit ​​body 3, an elastic element 16, and a strainer 4; the inner side of the snap-fit ​​body 3 snaps into one end of the elastic element 16, and the outer side of the snap-fit ​​body 3 snaps into the strainer 4, with the other end of the elastic element 16 extending into the strainer 4; the snap-fit ​​body 3 is provided with an air hole 2 that passes through the snap-fit ​​body 3, and the elastic element 16 is provided with a cavity 15 that communicates with the air hole 2; the strainer 4 has a feeding chamber inside and an overflow hole 5 on its outer wall.

[0049] To facilitate the extension and retraction of the elastic element 16, the present invention provides an air hole 2 on the snap-fit ​​body 3 and a cavity 15 on the elastic element 16. In use, the elastic element 16 is installed on the snap-fit ​​body 3, and complementary food is filled into the complementary food cavity inside the strainer 4. Then, the snap-fit ​​body 3 is installed on the strainer 4. At this time, because the complementary food cavity is full of complementary food, the elastic element 16 is in a compressed state and stores energy, and the cavity 15 of the elastic element 16 is squeezed and deformed, shrinking in size. When the baby sucks and bites the strainer 4, the complementary food in the strainer 4 flows out through the overflow hole 5 and is consumed by the baby. As the complementary food flows out, the complementary food in the cavity gradually decreases, and the compressed elastic element 16 gradually extends downwards. The shape of the cavity 15, which has shrunk due to compression deformation, gradually returns to its original shape. To compensate for the pressure drop caused by the extension of the elastic element 16, air enters through the air hole 2 on the snap-fit ​​body 3. The elastic element 16 gradually extends and descends, squeezing the internal space of the feeding cavity. The internal space of the feeding cavity becomes smaller, thereby collecting the remaining feeding food in the feeding cavity. The feeding food is concentrated at the overflow hole 5 for the baby to eat, making it easier for the baby to eat the feeding food and avoiding feeding food residue.

[0050] Furthermore, in order to ensure the effectiveness of the elastic element 16, such as Figure 1 , Figure 3 and Figure 8 As shown, the snap-fit ​​body 3 of the present invention is a cylindrical structure with a top cover and an opening at the bottom. An arc-shaped protrusion and an air hole 2 are provided along the axis of the cylindrical structure. The wall thickness of the top cover at the air hole 2 is greater than the wall thickness around the air hole 2. The top cover of the present invention has an arc-shaped protrusion at its top, and the bottom of the top cover can be an arc-shaped surface or a flat surface. This ensures that the wall thickness at the air hole 2 is greater than the wall thickness around the air hole 2. In other words, the wall thickness of the snap-fit ​​body 3 at the air hole 2 is thickened, making it less prone to bending and deformation during use, thus ensuring the permeability of the air hole 2 and guaranteeing gas compensation for the elastic element 16 during use, thereby ensuring the effectiveness of the elastic element 16.

[0051] Furthermore, for the convenience of babies, such as Figure 1 and Figure 3 As shown, the snap-fit ​​body 3 of the present invention has a hanging ring 1 at the top, which makes it easy for the baby to grasp with one or both hands when using it. Preferably, the two ends of the hanging ring 1 are located on both sides of the protrusion and connected to the snap-fit ​​body 3. The diameter of the hanging ring 1 gradually increases from the two ends to the middle, and is thickened in the middle part, which is mainly for the baby to grasp, to ensure the baby's feel when using it. The diameter of the hanging ring 1 gradually decreases at both ends, which can reduce the weight of the hanging ring 1 and further facilitate the baby's use.

[0052] Furthermore, to ensure the robustness of the connection in this invention, such as... Figure 3As shown, the snap-fit ​​body 3 of the present invention has a first snap-fit ​​protrusion 8 on its outer side. The cross-section of the first snap-fit ​​protrusion 8 is a right trapezoid, and the hypotenuse of the right trapezoid is located below the right angle side, which makes it easy for the snap-fit ​​body 3 to be inserted into the strainer 4 and snapped onto the inner wall of the strainer 4.

[0053] Furthermore, such as Figure 3 and Figure 8 As shown, the snap-fit ​​body 3 of the present invention has a second snap-fit ​​protrusion 9 on its inner side. The cross-section of the second snap-fit ​​protrusion 9 is a right trapezoid, with the hypotenuse of the trapezoid located below the right-angled side. In the design, the first snap-fit ​​protrusion 8 of the present invention is located above the second snap-fit ​​protrusion 9, thereby offsetting the arrangement positions of the first snap-fit ​​protrusion 8 and the second snap-fit ​​protrusion 9, which facilitates the manufacturing and installation of the snap-fit ​​body 3. Preferably, the inner diameter of the snap-fit ​​body 3 at the second snap-fit ​​protrusion 9 is smaller than the inner diameter of the strainer 4, which facilitates the expansion and contraction deformation of the elastic element 16.

[0054] Furthermore, to facilitate the installation and deformation of the elastic element 16, such as Figure 3 and Figure 8 As shown, one end of the elastic member 16 of the present invention, which has a cavity 15, is a snap-fit ​​end 17, which snaps onto the snap-fit ​​body 3 for easy assembly; the other end of the elastic member 16 is a free end 11, which is used to squeeze and collect supplementary food. The snap-fit ​​end 17 and the free end 11 are connected by a toothed sidewall 13, which facilitates the deformation of the elastic member 16. When the elastic member 16 is squeezed, the toothed sidewall 13 is squeezed and deformed, and gradually recovers its deformation as the squeezing force decreases. Preferably, for ease of manufacturing, the outer tooth tip thickness of the toothed sidewall 13 of the present invention is greater than the inner tooth tip thickness.

[0055] Furthermore, in order to reduce the deformation resistance of the elastic element 16 and ensure the collection effect of residual complementary food, such as Figure 3 and Figure 8 As shown, the outer wall surface of the free end 11 of the elastic member 16 of the present invention is a corrugated surface 12, and the top end of the corrugated surface 12 is in contact with the inner wall of the strainer 4, thereby reducing the resistance encountered by the elastic member 16 when it is extended and ensuring the collection effect of the elastic member 16 on the complementary food during the extension process.

[0056] Furthermore, to ensure the cleanliness of the colander 4 and facilitate its storage, such as... Figure 10 As shown, the present invention also includes an outer cover 18, the bottom of which is provided with a base. The outer cover 18 is fitted over the outside of the strainer 4 and is snapped into place with the strainer 4, which facilitates the storage of the present invention and ensures the cleanliness of the strainer 4.

[0057] Furthermore, such as Figure 3 , Figure 8 and Figure 9As shown, the strainer 4 of the present invention includes a strainer body and a connector 10. The connector 10 is snapped into place with a snap-fit ​​body 3, facilitating the installation of the snap-fit ​​body 3 on the strainer 4. To enrich the structural options of the strainer 4, the strainer body and the connector 10 can be movably or fixedly connected, and can be either a split structure or an integral structure. The strainer body includes a mating section 6 and a feeding end 7; the mating section 6 is a rotating body used to accommodate the elastic element 16 and slides with the elastic element 16; the feeding end 7 is a spindle-shaped body with an elliptical cross-section, the cross-sectional shape of which is the same as the shape of a baby's open mouth, making it easy for the baby to use, and an overflow hole 5 is provided on the feeding end 7 to allow complementary food to flow to the baby.

[0058] The snap-fit ​​body 3, elastic element 16, strainer body, and connector 10 of this invention are all made of liquid silicone, all of which meet food-grade requirements. The materials are safe and reliable, and can be sucked and bitten by babies during use, thus ensuring the safety of babies and improving their user experience. As a preferred embodiment, the connector 10 has a higher hardness than the strainer body, facilitating assembly and ensuring a strong connection. The strainer body has the lowest hardness compared to the snap-fit ​​body 3, elastic element 16, and connector 10, further improving the baby's taste experience.

[0059] As an embodiment of the present invention, such as Figure 9 As shown, the main body of the colander of the present invention is movably connected to the connector 10, preferably by a snap-fit ​​connection. In the design, the main body of the colander and the connector 10 are separate components. The main body of the colander also includes a snap-fit ​​end 17, which is connected to the mating section 6 and snaps onto the inner side of the connector 10. During use, the snap-fit ​​end 17 is snapped onto the inner side of the connector 10, meaning the colander main body is mounted on the connector 10. During cleaning, the colander main body can be detached from the connector 10 for separate cleaning.

[0060] As another embodiment of the present invention, such as Figure 3 As shown, the main body of the colander of the present invention is fixedly connected to the connector 10, preferably by adhesive bonding. In the design, the colander main body also includes a covering end 14, which is connected to the mating section 6 and used to connect to the connector 10. The covering end 14 covers the outside of the connector 10 and is integrally formed with the connector 10 using an adhesive bonding process. After the colander 4 is formed, the colander main body and the connector 10 become an integral structure, which can reduce the number of parts of the colander 4 and facilitate assembly and use.

[0061] To accommodate babies of different ages, such as Figures 1 to 7 As shown, the feeding end 7 of the present invention has a variety of structural forms, which can meet the needs of babies of different ages.

[0062] As an embodiment of the present invention, such as Figures 5 to 7As shown, the diameter of the major axis of the elliptical shape of the feeding end 7 of the present invention is smaller than the diameter of the cross-section of the mating section 6. That is, the shape of the feeding end 7 is smaller than that of the mating section 6. Because of its small shape, the feeding end 7 is easier to put into the mouth and is convenient for young babies (4 to 7 months old) to use.

[0063] Furthermore, in this embodiment, the sidewall of the feeding end 7 has multiple annular recesses that conform to the arc shape of the baby's teeth. The surface of the annular recesses is arc-shaped, which adds teething properties to the strainer 4 and further enriches the baby's user experience. In the design, there are multiple overflow holes 5, located in the annular recesses, and they are distributed in an array of large and small holes along the upper and lower surfaces of the spindle-shaped body to evenly overflow the complementary food.

[0064] As another embodiment of the present invention, such as Figures 1 to 4 As shown, the elliptical major axis diameter of the maximum cross-section of the feeding end 7 of the present invention is greater than the diameter of the cross-section of the mating section 6, that is, the feeding end 7 is larger than the mating section 6, which can increase the volume of the feeding cavity and is suitable for older babies (older babies are those relative to younger babies).

[0065] Furthermore, in this embodiment, there are multiple overflow holes 5, which are distributed in an array of large and small sizes on the upper and lower surfaces of the spindle-shaped body. The arc formed by connecting the center points of each row of overflow holes 5 has the same curvature as the arc of a baby's teeth, which is in line with the baby's eating habits.

[0066] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
