Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a milk preparation device. Background Technology

[0002] In related technologies, a formula preparation device includes a housing and a heating element, the heating element being located inside the housing, and the bottle being placed on the housing so that the formula preparation device can adjust the temperature of the bottle and / or shake it to mix it.

[0003] However, the milk preparation devices in related technologies suffer from problems such as low heating efficiency and uneven heating, which affect the user experience. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide a milk preparation device that offers high heating efficiency, uniform heating, and a good user experience.

[0005] The formula preparation device of this utility model embodiment includes:

[0006] A housing, comprising an inner shell and an outer shell, the inner shell being located within the outer shell, and the outer peripheral surface of the inner shell and the inner peripheral surface of the outer shell being spaced apart, the inner shell having an inner peripheral surface and a bottom surface, the inner peripheral surface and the bottom surface of the inner shell forming a receiving groove;

[0007] A heating element is disposed on the outer peripheral surface of the inner shell, the heating element extends circumferentially along the inner shell, and the heating element is arranged in a wave-like pattern on the outer peripheral surface of the inner shell.

[0008] In this embodiment of the formula preparation device, the heating element extends in a wave-like pattern along the circumference of the inner shell. The wave-like pattern has at least one high point (peak) and one low point (trough) in the circumference of the inner shell, which makes the contact between the heating element and the outer circumferential surface of the inner shell more sufficient. This increases the contact area between the heating element and the outer circumferential surface of the inner shell, and also improves the uniformity of the contact between the heating element and the outer circumferential surface of the inner shell. This improves the heating efficiency and heating uniformity of the formula preparation device, and enhances the user experience.

[0009] Optionally, the heating element is arranged in at least one ring around the outer peripheral surface of the inner shell.

[0010] In this embodiment of the formula preparation device, the heating element can be a single wavy ring or multiple rings, with each ring extending in a wavy shape. This ensures the contact area between the heating element and the outer circumferential surface of the inner shell, further improving the heating efficiency and uniformity of the formula preparation device, and enhancing the user experience.

[0011] Optionally, the heating element has peaks and troughs, and the number of peaks or troughs in the same ring of the heating element is N, where 3 ≤ N ≤ 9.

[0012] The formula preparation device of this utility model, by limiting the number of peaks or troughs of the heating element in the same circle, can ensure that the heating element has a sufficient circumferential path on the outer circumferential surface of the inner shell, thereby increasing the contact area between the heating element and the outer circumferential surface of the inner shell. Moreover, the peaks and troughs of the heating element can heat different positions on the outer circumferential surface of the inner shell, making the heating element heat evenly, improving the heating efficiency of the formula preparation device, shortening the heating time, and providing a better user experience.

[0013] Optionally, the outer peripheral surface of the inner shell is provided with a slot, and the heating element is disposed in the slot.

[0014] In this embodiment of the milk preparation device, the heating element is located in the slot, which improves the stability of the heating element installed on the outer circumferential surface of the inner shell and ensures heating efficiency.

[0015] Optionally, the outer peripheral surface of the inner shell is provided with a protrusion, and the slot is provided on the protrusion.

[0016] The milk preparation device of this utility model has a slot located on the protrusion, which facilitates the setting of the slot and ensures that the structural strength of the inner shell is not reduced due to the setting of the slot, thereby improving the overall strength of the shell.

[0017] Optionally, the slot is located on the lower side of the protrusion, and the milk preparation device further includes an abutment member that abuts against the lower side of the heating element.

[0018] In this embodiment of the milk preparation device, a slot is provided on the lower side of the protrusion, which facilitates the heating element to be inserted into the slot from the bottom of the outer shell. The abutment abuts against the lower side of the heating element to position the heating element, making it less likely to shift due to its own weight, thus ensuring the stability of the heating element installation and ensuring heating efficiency.

[0019] Optionally, the portion of the abutting member that abuts against the heating member is arranged opposite to the slot in the vertical direction.

[0020] In this embodiment of the milk preparation device, the abutment and the slot are arranged opposite each other in the vertical direction. Compared with the staggered arrangement, the heating element is more stable and ensures heating efficiency.

[0021] Optionally, the abutment is located on the lower side of the protrusion.

[0022] In this embodiment of the milk preparation device, the abutment is located on the lower side of the protrusion, which improves the stability of the heating element and ensures heating efficiency.

[0023] Optionally, there are multiple slots, which are arranged at intervals along the circumference of the inner shell. There are multiple protrusions, and each of the protrusions corresponds to one of the multiple slots. The abutment is provided on at least a portion of the multiple protrusions.

[0024] The formula preparation device of this utility model has multiple slots and multiple protrusions arranged in a one-to-one correspondence, which further improves the stability of the heating element installed on the outer peripheral surface of the inner shell and ensures heating efficiency.

[0025] Optionally, the plurality of protrusions include a first protrusion and a second protrusion, the lower side of the first protrusion being lower than the lower side of the second protrusion, and the slot being disposed on the lower side of the first protrusion and the lower side of the second protrusion.

[0026] The formula mixing device of this utility model has a height difference between the lower side of the first protrusion and the lower side of the second protrusion in the vertical direction. This allows the heating element to be wavy after being installed on the first and second protrusions, ensuring the contact area between the heating element and the outer peripheral surface of the inner shell, improving the heating efficiency and heating uniformity of the formula mixing device, and enhancing the user experience.

[0027] Optionally, the abutment is a threaded part, and the abutment is installed on the lower side of the second protrusion.

[0028] The milk preparation device of this utility model uses a threaded component to position the heating element below it, which is simple in structure. Moreover, the threaded component is installed on the lower side of the second protrusion, and there is enough space below the second protrusion to facilitate the installation of the threaded component, thereby improving assembly efficiency.

[0029] Optionally, the housing further includes a connecting portion located between the upper end of the inner shell and the upper end of the outer shell, and the connecting portion is connected to the outer peripheral surface of the inner shell and the inner peripheral surface of the outer shell, and the protrusion is connected to the connecting portion.

[0030] The formula preparation device of this utility model strengthens the seal between the inner shell and the outer shell by setting a connecting part, making it difficult for water to enter between the inner shell and the outer shell, and making it difficult for the heating element to come into contact with water or impurities, thus ensuring the safety and heating efficiency of the heating element and extending the service life of the heating element. In addition, the protrusion is connected to the connecting part, which strengthens the connection between the protrusion and the inner shell and facilitates the setting of the protrusion.

[0031] Optionally, the formula preparation device further includes a bottle holder, which is detachably disposed within the receiving slot.

[0032] The formula preparation device of this utility model has a bottle holder that is detachably installed in the receiving groove, making it convenient to remove the bottle holder for cleaning. Attached Figure Description

Detailed Implementation

[0044] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] like Figures 1-10 As shown, the formula preparation device of this embodiment includes a housing 1 and a heating element 2. The housing 1 includes an inner shell 11 and an outer shell 12. The inner shell 11 is located inside the outer shell 12, and the outer peripheral surface of the inner shell 11 and the inner peripheral surface of the outer shell 12 are spaced apart. The inner shell 11 has an inner peripheral surface and a bottom surface, and the inner peripheral surface and the bottom surface of the inner shell 11 form a receiving groove 13. The heating element 2 is disposed on the outer peripheral surface of the inner shell 11, and the heating element 2 extends circumferentially along the inner shell 11. The heating element 2 is arranged in a wave-like pattern on the outer peripheral surface of the inner shell 11.

[0046] In this embodiment of the formula preparation device, the heating element 2 extends in a wave-like shape along the circumference of the inner shell 11. The wave shape has at least one high position (peak) and one low position (trough) in the circumference of the inner shell 11, which makes the contact between the heating element 2 and the outer circumferential surface of the inner shell 11 more sufficient. This increases the contact area between the heating element 2 and the outer circumferential surface of the inner shell 11, and also improves the uniformity of the contact between the heating element 2 and the outer circumferential surface of the inner shell 11. This improves the heating efficiency and heating uniformity of the formula preparation device 100, and enhances the user experience.

[0047] Optionally, such as Figure 4 As shown, the heating element 2 is arranged in at least one ring around the outer peripheral surface of the inner shell 11.

[0048] Specifically, the heating element 2 can be a single wavy ring or multiple rings, with each ring extending in a wavy shape. This ensures the contact area between the heating element 2 and the outer circumferential surface of the inner shell 11, further improving the heating efficiency and heating uniformity of the milk preparation device 100, and enhancing the user experience.

[0049] Optionally, such as Figure 3 and Figure 4 As shown, the heating element 2 has peaks 21 and troughs 22. The number of peaks 21 or troughs 22 in the same ring of the heating element 2 is N, where 3≤N≤9.

[0050] Specifically, by limiting the number of peaks 21 or troughs 22 of the heating element 2 in the same circle, it can be ensured that the heating element 2 has a sufficient circumferential path on the outer circumferential surface of the inner shell 11, which increases the contact area between the heating element 2 and the outer circumferential surface of the inner shell 11. Moreover, the peaks 21 and troughs 22 of the heating element 2 can heat different positions on the outer circumferential surface of the inner shell 11, so that the heating element 2 is heated evenly, improving the heating efficiency of the milk preparation device 100, shortening the heating time, and providing a better user experience.

[0051] Specifically, when the number of peaks 21 or troughs 22 in the same ring of the heating element 2 is 3, the contact area between the heating element 2 and the outer peripheral surface of the inner shell 11 is increased, and different positions on the outer peripheral surface of the inner shell 11 can be heated, so that the heating is uniform and the heating efficiency is high.

[0052] When the number of peaks 21 or troughs 22 in the same ring of the heating element 2 is 9, the contact area between the heating element 2 and the outer peripheral surface of the inner shell 11 is further increased, thereby further improving the heating efficiency and the uniformity of heating.

[0053] Optionally, such as Figures 5-8 As shown, the outer peripheral surface of the inner shell 11 is provided with a slot 33, and the heating element 2 is disposed in the slot 33, which improves the stability of the heating element 2 on the outer peripheral surface of the inner shell 11 and ensures heating efficiency.

[0054] In some embodiments, the slot 33 may be formed by the outer peripheral surface of the inner shell 11 being recessed into the inner peripheral surface of the inner shell 11, and the slot 33 is circumferentially wavy, with the heating element 2 disposed in the slot 33.

[0055] Optionally, such as Figure 4 , Figure 7 and Figure 8 As shown, the outer peripheral surface of the inner shell 11 is provided with a protrusion 3, and the slot 33 is provided on the protrusion 3.

[0056] Specifically, the protrusion 3 extends along the vertical direction on the outer peripheral surface of the inner shell 11, and the slot 33 is provided on the protrusion 3. The slot 33 is convenient to be set, ensuring that the structural strength of the inner shell 11 is not reduced due to the setting of the slot 33, thereby improving the overall strength of the shell 1 and ensuring the service life of the shell 1.

[0057] It is understood that in another embodiment, the protrusion 3 is arranged around the outer peripheral surface of the inner shell 11, the slot 33 is formed on the side of the protrusion 3 away from the outer surface of the inner shell 11 and is wavy, and the heating element 2 is disposed in the slot 33.

[0058] Optionally, the slot 33 is provided on the lower side of the protrusion 3, so that the heating element 2 can be inserted into the slot 33 from the bottom of the housing 1.

[0059] Optionally, the formula preparation device 100 also includes an abutment 4, which abuts against the lower side of the heating element 2.

[0060] Specifically, the abutting part 4 abuts against the lower side of the heating element 2 to position the heating element 2, so that the heating element 2 is not easily displaced by its own gravity, ensuring the stability of the installation of the heating element 2 and ensuring heating efficiency.

[0061] Specifically, the abutment 4 can be located between two adjacent protrusions 3. The slot 33 and the abutment 4 together limit the heating element 2, further ensuring that the heating element 2 is firmly installed on the outer peripheral surface of the inner shell 11, and is not easily displaced by its own weight or external forces, thus ensuring heating efficiency.

[0062] Optionally, such as Figure 6 As shown, the part of the abutting member 4 that abuts against the heating member 2 is arranged opposite to the slot 33 in the vertical direction.

[0063] Specifically, the abutment 4 and the slot 33 are arranged opposite each other in the vertical direction. Compared with the staggered arrangement, the heating element 2 has higher stability and ensures heating efficiency.

[0064] Optionally, the abutment 4 is located on the lower side of the protrusion 3, which makes the heating element 2 more stable and ensures heating efficiency.

[0065] Optionally, there are multiple slots 33, which are arranged at intervals along the circumference of the inner shell 11. There are multiple protrusions 3, and each protrusion 3 corresponds to one of the multiple slots 33. The abutment 4 is provided on at least a portion of the multiple protrusions 3.

[0066] Specifically, multiple slots 33 and multiple protrusions 3 are provided in a one-to-one correspondence to further ensure the stable installation of the heating element 2 on the outer peripheral surface of the inner shell 11 and to ensure heating efficiency. The multiple protrusions 3 are arranged at intervals along the circumference of the inner shell 11, which further strengthens the structural strength of the inner shell 11.

[0067] Optionally, such as Figure 4 As shown, the plurality of protrusions 3 include a first protrusion 31 and a second protrusion 32. The lower side of the first protrusion 31 is lower than the lower side of the second protrusion 32. The slot 33 is provided on the first protrusion 31 and the lower side of the second protrusion 32.

[0068] Specifically, by having a height difference between the lower side of the first protrusion 31 and the lower side of the second protrusion 32 in the vertical direction, the heating element 2 can be made to appear wavy after being installed on the first protrusion 31 and the second protrusion 32, ensuring the contact area between the heating element 2 and the outer peripheral surface of the inner shell 11, improving the heating efficiency and heating uniformity of the milk preparation device, and enhancing the user experience.

[0069] Optionally, the abutment 4 is a threaded part, which is installed on the lower side of the second protrusion 32 to abut against the heating element 2, thereby ensuring the stability of the heating element 2 installation and ensuring heating efficiency.

[0070] Specifically, such as Figure 6 As shown, the threaded component includes a screw 41 and a head 42. The head 42 is located at one end of the screw 41, and the other end of the screw 41 is located on the lower side of the second protrusion 32. The end face of the head 42 connected to the screw 41 abuts against the heating element 2. It can be understood that the threaded component can be a screw, bolt, etc.

[0071] The milk preparation device of this utility model has a screw 41 that passes through the lower side of the second protrusion 32 and is mounted on the second protrusion 32. The upper end face of the head 42 can abut against the heating element 2 below the heating element 2, which improves the convenience of threaded installation and improves assembly efficiency.

[0072] Optionally, such as Figure 2 and Figure 4 As shown, the housing 1 also includes a connecting part 14, which is located between the upper end of the inner shell 11 and the upper end of the outer shell 12, and the connecting part 14 is connected to the outer peripheral surface of the inner shell 11 and the inner peripheral surface of the outer shell 12. The protrusion 3 is connected to the connecting part 14.

[0073] Specifically, the connecting part 14 connects the outer peripheral surface of the inner shell 11 and the inner peripheral surface of the outer shell 12, which strengthens the seal between the inner shell 11 and the outer shell 12, making it difficult for water to enter between the inner shell 11 and the outer shell 12, and making it difficult for the heating element 2 to come into contact with water or impurities, thus ensuring the safety and heating efficiency of the heating element 2 and extending its service life. In addition, the protrusion 3 is connected to the connecting part 14 and extends in the vertical direction, which strengthens the connection between the protrusion 3 and the inner shell 11, facilitates the setting of the protrusion 3, and strengthens the structural strength of the inner shell 11.

[0074] Optionally, both the first protrusion 31 and the second protrusion 32 extend downward from the lower side of the connecting portion 14, and the dimension of the first protrusion 31 in the vertical direction is greater than the dimension of the second protrusion 32 in the vertical direction, so that the lower side of the first protrusion 31 is lower than the lower side of the second protrusion 32.

[0075] Optionally, there are at least two abutting members 4, and the at least two abutting members 4 are arranged at circumferential intervals along the inner shell 11.

[0076] Specifically, at least two abutting parts 4 abut against and support the heating element 2 to ensure that the heating element 2 is firmly installed on the outer peripheral surface of the inner shell 11.

[0077] Optionally, such as Figure 2 and Figure 3 As shown, the formula preparation device 100 also includes a bottle holder 5, which is detachably disposed in the receiving groove 13, making it convenient to remove the bottle holder 5 for cleaning.

[0078] Specifically, the bottle holder 5 can be detachably installed in the receiving groove 13 by means of magnetic components. When the bottle holder 5 is placed in the receiving groove 13, the bottle holder 5 is installed stably in the receiving groove 13 by the magnetic attraction between the magnetic components. When the bottle holder 5 is removed from the receiving groove 13, the bottle holder 5 is removed from the receiving groove 13 by means of external force to overcome the magnetic attraction between the magnetic components.
