[0022] 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. Example

[0023] like Figure 1-8 As shown, an embodiment of the present invention provides an ice cream heating spoon, including a spoon handle 1 and a spoon head 2. The spoon head 2 has a cavity 21 inside, and a heating base 22 is provided inside the cavity 21. The heating base 22 integrates a heating element 23 and extends a plurality of heat-conducting ribs 24 to the outer periphery of the heating element 23 to the inner wall of the spoon head 2. The bottom of the spoon head 2 is provided with a notch 25 communicating with the cavity 21, and the notch 25 is encapsulated with a bottom cover 26. The spoon handle 1 is connected to the spoon head 2, and the spoon handle 1 is provided with a control component for powering and controlling the heating element 23.

[0024] Both the spoon head 2 and the bottom cover 26 are made of food-grade stainless steel. The heating base 22 and the heat-conducting ribs 24 are made of pure copper or aluminum alloy and are inlaid and combined with the stainless steel spoon head 2. Through the brazing process, at high temperature, a metal solder (such as silver-based solder) with a lower melting point than both is used as a medium to firmly weld the copper or aluminum heat-conducting components to the inner wall of the stainless steel spoon head 2. At the same time, high thermal conductivity insulating silicone grease is applied to the contact surface to fill the micro gaps and reduce the contact thermal resistance.

[0025] like Figure 1-8 As shown, in some embodiments, the inner wall of the spoon tip 27 region of the spoon head 2 is thinned, the spoon base 28 region of the spoon head 2 is thickened, and the horizontal height of the spoon base 28 is higher than that of the spoon tip 27.

[0026] The thinner tip 27 reduces thermal resistance, allowing heat to be transferred to the surface more quickly, prioritizing the softening of the hardest and most difficult-to-scoop ice cream tip. The thicker base 28 increases structural strength to withstand the leverage force during scooping and also slows down the heating due to its larger heat capacity, preventing overheating at the handle connection. The base 28, being higher than the tip 27, forms a natural angle, conforming to ergonomics and facilitating scooping. This achieves a differentiated heating and user experience with "quick entry with the tip 27, uniform softening of the spoon body, and a robust and durable base 28," while also improving the convenience of scooping and the structural reliability of the product.

[0027] like Figure 1-8 As shown, in some embodiments, the heat-conducting ribs 24 on the heating base 22 are radially distributed, and their extension direction includes at least a main heat-conducting rib 241 leading to the spoon tip 27 and a secondary heat-conducting rib 242 leading to the spoon base 28. The cross-sectional area of ​​the main heat-conducting rib 241 is larger than the cross-sectional area of ​​the secondary heat-conducting rib 242.

[0028] The larger the cross-sectional area of ​​a conductor, the smaller its thermal resistance and the greater the heat flow allowed. By increasing the cross-sectional area of ​​the main heat-conducting rib 241, it is equivalent to widening the lanes of the "heat highway" leading to the spoon tip 27, making its heat transfer capacity exceed that of other paths. The functional distinction between the main heat-conducting rib 241 and the secondary heat-conducting rib 242 is physically strengthened, which can significantly improve the heating rate of the spoon tip 27, realize the rapid entry of the spoon tip 27, and promote the more synchronous reaching of the working temperature of each area of ​​the spoon head 2.

[0029] like Figure 1-8 As shown, in some embodiments, a sealing gasket 251 is embedded in the notch 25, the bottom cover 26 and the notch 25 are interference fit, and the sealing gasket 251 is provided with a plurality of sealing protrusions 252 on the side facing the bottom cover 26.

[0030] As a flexible medium, the sealing gasket 251 fills the micro-unevenness. The multiple sealing protrusions 252 on it will generate greater local deformation when under pressure, forming multiple continuous, high-pressure sealing contact lines. This greatly increases the path required for liquid penetration and can effectively resist material deformation caused by long-term hot and cold cycles, ensuring the long-term sealing of the cavity 21 of the spoon head 2 and preventing moisture intrusion that could lead to short circuits and failures.

[0031] like Figure 1-8 As shown, in some embodiments, the spoon handle 1 includes a housing 11 and a waterproof sleeve 12 fitted over the housing 11, and a connector 13 is provided at one end of the housing 11; The spoon head 2 has a socket 29 on one side of the spoon base 28 for inserting the connector 13, and the connector 13 is interference-fitted with the socket 29.

[0032] The interference fit between the connector 13 and the socket 29 relies on the elastic deformation of the material to generate huge static friction, achieving a reliable connection without fasteners. The waterproof sleeve 12 independently provides insulation and a comfortable grip for the handheld part. It enables quick and stable assembly of the spoon head 2 and the spoon handle 1 without the need for screws or other additional parts, reducing production costs and improving assembly efficiency. The interference fit ensures the connection strength during use and prevents loosening.

[0033] like Figure 1-8 As shown, in some embodiments, the connector 13 is provided with limiting grooves 131 on both sides, and the inner wall of the socket 29 is provided with limiting ribs 291 that respectively engage with the two limiting grooves 131 on both sides.

[0034] The connection between the limiting rib 291 and the limiting groove 131 is equivalent to embedding a "key" in the connection interface, which mechanically prevents relative rotation between the spoon head 2 and the spoon handle 1, greatly enhancing the ability of the connection point to resist the torque generated when scooping ice cream and preventing the interface from loosening after long-term use.

[0035] like Figure 1-8 As shown, in some embodiments, the control components include a control board 14 disposed inside the spoon handle 1 and a battery 15. The heating element 23 is electrically connected to the control board 14 via a high-temperature resistant wire. The control board 14 integrates a switch 141 and a charging interface 142. The heating element 23 is one of a thick film heating element, a ceramic heating element, or a MCH (metal-ceramic heater).

[0036] High-temperature resistant wires ensure that heat will not damage electrical components along the wires. The control board 14, as the "brain", integrates power management, switch 141 control and charging management functions, spatially separating all live parts from the heating part of the spoon head 2, improving electrical safety. The integrated design makes the product structure compact and provides a complete user experience.

[0037] like Figure 1-8 As shown, in some embodiments, the end of the spoon handle 1 is fitted with a tail cap 16, and the tail cap 16 is provided with a waterproof button 161 and a waterproof charging plug 162 corresponding to the switch 141 and the charging interface 142.

[0038] The tail cap 16 serves as the end cap of the spoon handle 1. The waterproof button 161 on it prevents water from entering when the switch 141 is triggered by the internal sealing ring structure. The waterproof charging plug 162 is an independent physical barrier that completely seals the charging interface 142 when not charging.

[0039] like Figure 1-8 As shown, in some embodiments, the outer shell 11 includes a lower shell 17 and an upper shell 18. The lower shell 17 and the upper shell 18 are both provided with fixing ribs 19 for limiting the battery 15. The lower shell 17 is provided with studs 171 for screwing and fixing the control board 14.

[0040] The fixing ribs 19 limit the soft-pack battery 15 from all sides to prevent it from shaking or shifting inside the housing. The studs 171 provide a precise mounting surface and reliable mechanical fixing point for the control board 14, preventing it from being suspended or vibrating, and ensuring the stability and reliability of the internal components of the spoon handle 1. The lower shell 17 and the upper shell 18 are also provided with grooves that engage with the tail cap 16. Rubber gaskets are also provided inside the grooves for sealing.

[0041] In summary, efficient heating is achieved by combining the heating base 22 and its radial heat-conducting ribs 24 with the inner wall of the spoon head 2. The thinning of the inner wall of the spoon tip 27 and the thickening and raising of the spoon base 28 allow the spoon tip 27 to quickly cut into the ice cream while the spoon base 28 has a robust and ergonomic structure. The structure of the main heat-conducting rib 241 leading to the spoon tip 27 with a cross-sectional area larger than that of the secondary heat-conducting rib 242 significantly improves the heating efficiency. The bottom cover 26 ensures long-term reliable sealing by pressing the sealing gasket 251 with multiple sealing protrusions 252 through an interference fit. The connector 13 of the spoon handle 1 and the socket 29 of the spoon head 2 through an interference fit and the limiting rib 291 and the limiting groove 131 are connected to achieve a firm connection and resistance to torsion. The waterproof button 161 and the waterproof charging plug 162 of the tail cover 16 comprehensively improve the internal structural stability and overall waterproof safety.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
