Description

Technical Field

[0001] This utility model relates to the field of milk shaker technology, specifically to a milk shaker that reduces surface temperature rise. Background Technology

[0002] In the field of infant feeding equipment, bottle shakers are widely used as an important tool to help mix formula and water and promote dissolution. With technological advancements and evolving consumer demands, bottle shakers with heating functions are gradually becoming the mainstream in the market. However, existing bottle shakers with heating functions face significant technical bottlenecks in practical use.

[0003] Currently, most baby shakers use a traditional design, where heat generated by the heating element is transferred to the bottle primarily through air convection and structural conduction to heat the milk. However, this heat transfer method lacks an effective isolation and guidance mechanism, allowing a large amount of heat to diffuse randomly into the shaker's casing, causing a rapid increase in surface temperature. When a user accidentally comes into contact with the hot casing during operation, burns are highly likely, posing a significant safety hazard, especially for families with infants. Furthermore, excessively high surface temperatures can create a complex temperature field inside the shaker, resulting in uneven heating of the milk within the drum, affecting both heating efficiency and milk quality.

[0004] Furthermore, the layout and connection methods of the internal components of existing milk shakers fail to adequately consider heat management. Significant heat loss during transfer not only reduces heating efficiency and increases energy consumption but also shortens the lifespan of the shaker, impacting the user experience. Therefore, optimizing the structure of milk shakers to effectively reduce the temperature rise of the shell surface while ensuring efficient heating of milk has become an urgent technical problem to be solved. Utility Model Content

The heating air duct of the heating device is connected to the support base, and the air outlet of the heating air duct faces the inner cylinder of the milk shaker so as to guide the hot air to the baby bottle inside the inner cylinder of the milk shaker.

[0014] As a further embodiment of this utility model: the hot air from the heating device forms a flow channel through the thermal insulation layer between the supporting base and the inner cylinder of the milk shaker, and flows along the flow channel toward the inner cylinder of the milk shaker.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1) Through the support base and the thermal insulation layer it forms, heat is difficult to be directly conducted to the shell through the structure, which forces more heat to be concentrated in the inner drum and bottle area, reducing the possibility of heat diffusion to the shell, thereby reducing the temperature rise of the shell surface and allowing more heat to be concentrated in the inner drum area for heating the bottle, thus improving heat utilization efficiency.

[0024] 2) The sealing structure of the silicone seal makes it difficult for heat to be transferred through the gap between the support base and the shell, forcing more heat to be confined to the inner drum area of ​​the milk shaker, reducing the path of heat diffusion to the shell, thereby significantly reducing the temperature rise of the shell surface and allowing more heat to be used to heat the bottle, thus improving heat utilization efficiency.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-5 In this embodiment of the invention, a milk shaker for reducing surface temperature rise includes:

[0036] Housing 1, which constitutes the external support structure of the milk shaker;

[0037] The inner cylinder 2 for shaking milk is disposed inside the shell 1 and is used to support the milk bottle;

[0038] The driving component 3 is disposed inside the housing 1 and connected to the milk shaking inner cylinder 2, and is used to drive the milk shaking inner cylinder 2 to move.

[0039] The support base 4 is installed inside the housing 1 and located between the housing 1 and the inner cylinder 2 of the milk shaking, so that a thermal insulation layer 5 is formed between the support base 4 and the inner cylinder 2 of the milk shaking.

[0040] In this utility model, the shell 1 constitutes the external support structure of the milk shaker, which is used to accommodate the internal components and provide overall support for the milk shaker; the milk shaker inner cylinder 2 is set inside the shell 1, and its main function is to support the milk bottle. The milk bottle is placed in the milk shaker inner cylinder 2 for shaking and heating operations. The drive component 3 is also set inside the shell 1 and connected to the milk shaker inner cylinder 2. The operation of the drive component 3 (such as a motor) drives the milk shaker inner cylinder 2 to move, thereby achieving the mixing of the liquid in the milk bottle.

[0041] The support base 4 is a key component of this utility model. It is installed inside the shell 1 and located between the shell 1 and the inner bottle 2. The support base 4 and the inner bottle 2 are spaced apart, forming a thermal insulation layer 5 between them. The presence of this thermal insulation layer 5 can effectively block the transfer of heat from the inner bottle 2 area to the shell 1, thereby reducing heat loss to the surface of the shell 1 and lowering the surface temperature rise of the shell 1. From the perspective of heat transfer principle, heat follows the law of conduction from high temperature area to low temperature area during the transfer process. The setting of the thermal insulation layer 5 to a certain extent blocks the direct conduction path of heat from the inner bottle 2 (high temperature area) to the shell 1 (low temperature area), so that more heat is concentrated in the inner bottle 2 area for heating the bottle, thereby improving the heat utilization efficiency. That is, through the presence of the thermal insulation layer 5, it is difficult for heat to be directly conducted to the shell 1 through the structure, forcing more heat to be concentrated in the inner bottle 2 and bottle area, reducing the possibility of heat diffusion to the shell 1, thereby reducing the surface temperature rise of the shell 1.

[0042] In this embodiment of the utility model, a silicone sealant 6 is provided between the bearing base 4 and the shell 1. The silicone sealant 6 is used to block heat from being transferred from the milk-shaking inner cylinder 2 area to the shell 1.

[0043] The silicone seal 6 has good thermal insulation performance and low thermal conductivity, which can effectively hinder the conduction of heat. The silicone seal 6 is placed between the support base 4 and the shell 1. Utilizing the elastic and deformable properties of silicone material, it can tightly fill any gaps that may exist between the support base 4 and the shell 1. When the milk shaker is working, heat accumulates in the milk shaker inner cylinder 2 area and attempts to be transferred to the shell 1 through the gap between the support base 4 and the shell 1. The silicone seal 6 forms a barrier between the two, blocking the path of heat transfer and confining the heat to the milk shaker inner cylinder 2 area as much as possible, thereby reducing the diffusion of heat to the shell 1 and achieving the purpose of reducing the surface temperature rise of the shell 1.

[0044] In this embodiment of the present invention, the inner cylinder 2 is movably connected to the support base 4. The support base 4 surrounds the inner cylinder 2 and is spaced apart from the inner cylinder 2, so as to form the thermal insulation layer 5 between the support base 4 and the inner cylinder 2.

[0045] Heat transfer mainly occurs through three mechanisms: conduction, convection, and radiation. When the inner drum 2 and the supporting base 4 are tightly connected, heat is quickly transferred from the inner drum 2 to the supporting base 4 via conduction, and then to the outer shell 1. However, the presence of a gap, where the air inside is a poor conductor of heat, effectively slows down the rate of heat conduction. At the same time, the gap disrupts the path of heat convection, making it difficult for hot air to form an effective convection circulation between the inner drum 2 and the supporting base 4, further preventing heat transfer. This creates a thermal insulation layer 5 between the supporting base 4 and the inner drum 2, reducing the amount of heat transferred from the inner drum 2 to the supporting base 4 and the outer shell 1.

[0046] In this embodiment of the utility model, the supporting base 4 and the milk-shaking inner cylinder 2 are coaxially connected cylindrical structures;

[0047] The inner diameter of the supporting base 4 is larger than the outer diameter of the milk-shaking inner cylinder 2.

[0048] Its design principle lies in optimizing the heat transfer path and motion stability. Specifically, the coaxial structure ensures the regularity of the spatial layout of the two, so that the inner cylinder 2 of the milk shaker is subjected to uniform force when it moves within the support base 4, avoiding the aggravation of shaking caused by eccentricity, thereby ensuring smooth milk shaking. The inner diameter of the support base 4 is larger than the outer diameter of the inner cylinder 2 of the milk shaker, which can form a uniform annular gap between the two, which can serve as a thermal isolation space. When the milk shaker is working, the heat generated by the inner cylinder 2 of the milk shaker diffuses to the surroundings. The air in the annular gap acts as a poor conductor of heat, effectively blocking the heat from being transferred to the support base 4 by conduction, thereby reducing the heat transfer to the shell 1 and achieving the effect of reducing surface temperature rise. At the same time, the uniform annular gap also provides a standardized channel space for the realization of functions such as hot air guidance, which facilitates the uniform distribution of heat flow.

[0049] In this embodiment of the present invention, a heating device 7 for heating the baby bottle on the inner cylinder 2 is also provided inside the housing 1. The heating air duct 8 of the heating device 7 is connected to the support base 4, and the air outlet 9 of the heating air duct 8 faces the inner cylinder 2 to guide the hot air to the baby bottle inside the inner cylinder 2.

[0050] Due to the directional guidance of the air outlet 9, the hot air can flow precisely to the bottle inside the shaking inner cylinder 2. At the same time, the heat insulation layer 5 formed by the gap between the support base 4 and the shaking inner cylinder 2 can reduce the transfer of heat to the shell 1 on the one hand, and provide a relatively closed transmission channel for the hot air on the other hand, so that the hot air can act on the bottle more concentratedly and efficiently, and avoid excessive heat loss to the surrounding environment during the transmission process.

[0051] In this embodiment of the present invention, the hot air from the heating device 7 flows through the heat insulation layer 5 between the supporting base 4 and the inner cylinder 2 to form a flow channel, and flows along the flow channel to the inner cylinder 2.

[0052] When the heating device 7 generates hot air, the hot air will preferentially flow through the channel with less resistance under the action of pressure difference. Since the guide channel is relatively closed and has a clear direction, the hot air can be stably transmitted in it. The heat is transferred to the inner drum 2 of the milk shaker through air convection. At the same time, the air or heat insulation material used in the heat insulation layer 5 has poor thermal conductivity, which can effectively prevent the heat carried by the hot air from spreading to the support base 4 and the shell 1, so that the heat is mainly concentrated in the area of ​​the inner drum 2 of the milk shaker, thereby achieving precise heating of the milk bottle and control of the surface temperature rise of the shell 1.

[0053] In this embodiment of the present invention, the top edge of the bearing base 4 is provided with an annular protrusion structure 10, and the silicone sealant 6 is arranged around the annular protrusion.

[0054] The inner side of the silicone seal 6 is tightly fitted with the annular protrusion, and the outer side is fitted with the housing 1.

[0055] The annular protrusion 10 on the top edge of the support base 4 provides a precise installation positioning reference for the silicone seal 6. The silicone seal 6 has good elasticity and plasticity. When it is set around the annular protrusion, its inner side can fit tightly against the surface of the annular protrusion. The elastic deformation of the silicone material itself fills the tiny gaps, forming a physical barrier to prevent heat from being transferred from the top of the support base 4 to the silicone seal 6 through contact conduction. Its outer side cooperates with the shell 1, and the sealing properties of silicone fill the gap between the support base 4 and the shell 1, reducing the heat loss path caused by hot air convection. Through this structural design, the heat generated in the milk-shaking inner cylinder 2 area is confined to the inside as much as possible, reducing the transfer to the shell 1 and achieving a heat insulation effect.

[0056] In this embodiment of the utility model, the cross-section of the silicone seal 6 is an L-shaped structure (which can be understood as a horizontally placed L-shaped structure from the figure), including a vertical fitting part 11 and a horizontal blocking part 12. The vertical fitting part 11 is arranged along the side wall of the annular protrusion of the bearing base 4 and fits tightly. The horizontal blocking part 12 extends to the top of the heat insulation layer 5 to prevent heat from overflowing to the shell 1.

[0057] The lateral blocking portion 12 also extends to the top of the support base 4 and fits tightly against the inner side of the top of the housing 1.

[0058] The vertical fitting part 11 is tightly fitted along the annular protrusion of the support base 4. Utilizing the elastic deformation properties of the silicone material, it fills the gaps in the side wall, preventing heat from being transferred to the shell 1 through structural conduction in the vertical direction. The horizontal blocking part 12 extends to the top of the heat insulation layer 5, sealing the top opening of the heat insulation layer 5 or blocking it to a certain extent, thereby blocking hot air or preventing hot air from escaping and diffusing to the convection path of the shell 1 through the top. At the same time, the horizontal blocking part 12 extends to the top of the support base 4 and is tightly fitted to the inner side of the top of the shell 1, forming a horizontal sealing barrier, further isolating heat from being transferred to the shell 1 through the top gap. In other words, through the double sealing structure of vertical and horizontal, a three-dimensional heat insulation barrier is constructed, reducing the transfer of heat from the milk-shaking inner cylinder 2 area to the shell 1 in all directions.

[0059] In this embodiment of the present invention, the inner side of the housing 1 is provided with a groove 13 corresponding to the silicone seal 6, and the silicone seal 6 is embedded in the groove 13.

[0060] The slot 13 and the silicone seal 6 are embedded and fitted together, so that the silicone seal 6 is firmly installed in the designated position, avoiding the seal from loosening or shifting due to long-term use, vibration and other factors, ensuring that the sealing structure always maintains good sealing performance, blocking heat transfer in a long-term and stable manner, and reducing the temperature rise of the housing 1 surface.

[0061] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
