Description

Technical Field

[0001] This invention relates to the field of electromagnetic cooking appliances, and in particular to a high-strength, fast-temperature-sensing panel with an annular groove. Background Technology

[0002] Since electromagnetic heating technology was applied to the cooking industry, temperature control has always been a major challenge. The mainstream induction cooker structures are as follows:

[0003] The first structure, from top to bottom, consists of the cookware, a microcrystalline panel (approximately 4mm thick), and a sensor assembly (including a shell, insulation layer, and sensor, with the sensor located in the center of the coil). Because the microcrystalline panel is flat, and the sensor assembly is tightly attached to its bottom surface, this structure results in a significant distance between the temperature sensor and the cookware. The cookware's heat must first be conducted to the 4mm thick microcrystalline panel, causing it to heat up, before the panel can transfer the heat to the sensor. This leads to slow heat conduction. Normal home cooking typically requires a heating temperature not exceeding 280 degrees Celsius. However, due to the slow temperature sensing, even thinner cookware may be red-hot before the sensor detects the temperature. This leads to the following consequences: 1. Safety hazards: severely delayed temperature control could allow oil to reach its ignition point when the oil level is low, potentially causing a fire; 2. Excessively high oil temperatures produce large amounts of aromatic hydrocarbons, which are highly carcinogenic; 3. Poor taste in Chinese dishes.

[0004] The second structure involves an opening at the center of the microcrystalline glass relative to the coil, allowing the temperature sensor assembly to directly contact the cookware. The sensor assembly includes a shell, an insulating layer, and the sensor itself. The sensor shell is typically made of metal. When a cookware is placed on top of the sensor, the metal shell is exposed to an alternating magnetic field, causing it to heat up (under the cookware on an induction cooker, all metal heats up, and the closer to the pot, the faster the heat generation), thus leading to inaccurate temperature sensing. Furthermore, according to safety regulations, an insulating layer is required beneath the sensor shell, typically made of engineering plastic with a temperature resistance of around 350℃, which has relatively poor thermal conductivity. The biggest drawback of this structure is that the shell continuously generates heat, preventing accurate temperature readings of the cookware and hindering breakthroughs in temperature sensing technology. Additionally, waterproofing and anti-aging features require additional costs.

[0005] Both of these structures share the following drawbacks: To prevent sensor leakage, an outer casing is required, resulting in a larger sensor assembly. This necessitates a dedicated mounting location on the coil, typically centered to minimize the coil's heating efficiency. The electromagnetic heating primarily concentrates on a ring approximately 90mm in diameter, making the sensor too far from the high-temperature zone for accurate temperature feedback. Almost all induction cooker manufacturers conduct heating experiments with different cookware on their induction cookers, recording temperature change curves. These curves are then compared to the recorded curves to assess the cookware's heating performance. However, unpredictable variations in cookware quality, type, and ingredients during actual use limit the induction cooker's ability to become a mainstream cooking tool, primarily used for boiling water, hot pot, and porridge. Regarding the panel, the inability to accurately sense temperature necessitates the use of heat-resistant microcrystalline glass to reduce the risk of overheating, thus contributing to the high cost of the induction cooker panel. Summary of the Invention

[0006] The purpose of this invention is to propose a high-strength, fast-sensing panel with an annular groove to solve the problem of severe temperature lag in current electromagnetic cooking appliances.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A high-strength, rapid-sensing temperature panel with annular grooves includes a panel body, a wear-resistant thermally conductive cap, and temperature sensors. The top surface of the panel body has several annular grooves, forming a support platform within the area enclosed by these grooves. The outer walls of the annular grooves are inclined, creating a structure that is wider at the top and narrower at the bottom. The support platform has through-holes. The bottom of the wear-resistant thermally conductive cap has an opening, and its sidewalls are inserted into the annular grooves. A heat-resistant adhesive is filled between the wear-resistant thermally conductive cap and the annular grooves. The outer wall of the wear-resistant thermally conductive cap is in close contact with the outer wall of the annular grooves. A gap exists between the inner top wall of the wear-resistant thermally conductive cap and the top surface of the support platform. The top surface of the wear-resistant thermally conductive cap is not lower than the top surface of the panel body. The temperature sensors are fixed within the through-holes, with the tops of the temperature sensors abutting against the wear-resistant thermally conductive caps.

[0009] Preferably, the top surface of the wear-resistant thermal conductive cap is higher than the top surface of the panel body, and the upper sidewall of the wear-resistant thermal conductive cap is provided with an inclined transition surface, which makes the part of the wear-resistant thermal conductive cap that is higher than the top surface of the panel body form a structure that is smaller at the top and larger at the bottom.

[0010] Preferably, the bottom of the transition surface is not lower than the top surface of the panel body.

[0011] Preferably, the top surface of the support platform is lower than the top surface of the panel body, and the top surface of the wear-resistant and heat-conducting cap is flush with the top surface of the panel body.

[0012] Preferably, the top surface of the wear-resistant and heat-conducting cap is provided with a boss, and the side wall of the boss forms an obtuse angle or is tangent to the top surface of the wear-resistant and heat-conducting cap.

[0013] Preferably, the bottom of the wear-resistant thermally conductive cap is provided with a thinning area, and the temperature sensor and the wear-resistant thermally conductive cap abut against the thinning area.

[0014] Preferably, the thinning area is a receiving groove, the top of the receiving groove is an upwardly arched arc surface, and both the receiving groove and the receiving hole are filled with heat-resistant adhesive. The temperature sensor is fixed relative to the wear-resistant and temperature-conducting cap through the heat-resistant adhesive.

[0015] Preferably, the inner wall of the wear-resistant heat-conducting cap and the inner wall of the annular groove are clearance-fitted; the inner top wall of the wear-resistant heat-conducting cap and / or the top surface of the support platform are provided with protrusions or adhesive grooves.

[0016] Preferably, the inner wall of the wear-resistant thermally conductive cap gradually slopes outward from top to bottom.

[0017] Preferably, the inner wall of the annular groove is an inclined surface, and the upper part of the inner wall of the annular groove slopes away from the outer wall of the annular groove.

[0018] One of the above technical solutions has the following beneficial effects:

[0019] 1. By reducing the distance between the temperature sensor and the cookware, the temperature of the cookware can be transmitted to the temperature sensor more quickly, thereby effectively improving the speed of temperature sensing and significantly reducing the lag in temperature detection; the temperature control is more accurate.

[0020] 2. The material of the wear-resistant thermal conductive cap can be selected according to the actual use scenario of the product, making it applicable to a wider range of scenarios;

[0021] 3. By setting an annular groove, the panel body can still have good waterproof performance even if there are receiving holes, which can effectively protect the electrical components inside the electromagnetic cooking appliance.

[0022] 4. By setting the outer wall of the annular groove as a slope, a structure that is larger at the top and smaller at the bottom is formed. When the wear-resistant and temperature-conducting cap is installed in the annular groove, the wear-resistant and temperature-conducting cap can be supported on the annular groove by abutting against the outer wall of the annular groove through its own side wall. The inner top wall of the wear-resistant and temperature-conducting cap is suspended above the support platform. This allows the wear-resistant and temperature-conducting cap to withstand greater impact strength after being installed in the annular groove without causing the panel body to break.

[0035] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] This embodiment discloses a high-strength, fast-sensing temperature panel with an annular groove 11, such as Figure 1-7 As shown, the panel includes a panel body 1, a wear-resistant and temperature-conducting cap 2, and a temperature sensor 3. The top surface of the panel body 1 has several annular grooves 11, forming a support platform 12 within the area enclosed by the annular grooves 11. The outer wall of the annular grooves 11 is inclined to create a structure that is wider at the top and narrower at the bottom. The support platform 12 has through-holes 13. The bottom of the wear-resistant and temperature-conducting cap 2 has an opening, and the side wall of the wear-resistant and temperature-conducting cap 2 is inserted into the annular grooves 11. Temperature-resistant adhesive 4 is filled between the wear-resistant and temperature-conducting cap 2 and the annular grooves 11. The outer wall of the wear-resistant and temperature-conducting cap 2 is in close contact with the outer wall of the annular grooves 11. A gap is left between the inner top wall of the wear-resistant and temperature-conducting cap 2 and the top surface of the support platform 12. The top surface of the wear-resistant and temperature-conducting cap 2 is not lower than the top surface of the panel body 1. The temperature sensors 3 are fixed within the through-holes 13, and the top of the temperature sensors 3 abuts against the wear-resistant and temperature-conducting cap 2.

[0037] This invention involves creating an annular groove 11 on the top surface of the panel body 1, and fixing a wear-resistant thermally conductive cap 2 within the annular groove 11. The outer wall of the annular groove 11 is sloped, forming a structure that is wider at the top and narrower at the bottom. When the wear-resistant thermally conductive cap 2 is installed in the annular groove 11, its sidewalls abut against the outer wall of the annular groove 11, thus providing support. The inner top wall of the wear-resistant thermally conductive cap 2 is suspended above a support platform 12. Specifically, the top surface of the support platform 12 can be flush with the top surface of the panel body 1, while the wear-resistant thermally conductive cap 2... When the temperature-conducting cap 2 is installed into the annular groove 11, the inner top wall of the wear-resistant temperature-conducting cap 2 is higher than the top surface of the panel body 1; alternatively, the top surface of the support platform 12 can be lower than the top surface of the panel body 1, so as to achieve the effect of leaving a gap between the wear-resistant temperature-conducting cap 2 and the top surface of the support platform 12 when it is installed into the annular groove 11. When the wear-resistant temperature-conducting cap 2 is subjected to downward pressure from the cookware, since the inner top wall of the wear-resistant temperature-conducting cap 2 does not contact the top surface of the support platform 12, the outer wall of the wear-resistant temperature-conducting cap 2 applies pressure to the outer wall of the annular groove 11. At this time, the pressure borne by the outer wall of the annular groove 11 can be divided into... The pressure can be divided into vertical and horizontal pressures. First, regarding the vertical pressure, since part of the pressure is decomposed into horizontal pressure, the vertical pressure is smaller compared to the structure where the wear-resistant heat-conducting plate is directly supported by the bottom of the groove. Furthermore, since the vertical pressure is applied to the sidewall of the groove, the thickness of the panel body 1 at the stress point is greater, thus enabling it to withstand greater vertical pressure. As for the horizontal pressure, since the pressure is transmitted horizontally, and the distance between the sidewall of the groove and the sidewall of the panel body 1 is larger than the thickness of the panel body 1, the panel body 1 can withstand greater horizontal pressure. Therefore, the structure of this invention allows the wear-resistant heat-conducting cap 2 to withstand greater impact strength after being installed in the annular groove 11 without breaking the panel body 1. In particular, with the structure where the wear-resistant heat-conducting cap 2 protrudes from the panel body 1, when heavy objects are placed on the wear-resistant heat-conducting cap 2, such as a pot full of water, the panel body 1 is less likely to break due to impact, making it safer for users and improving product quality.

[0038] Furthermore, the sidewall of the wear-resistant heat-conducting cap 2 is inserted into and fixed in the annular groove 11. The annular groove 11 can limit the sidewall of the wear-resistant heat-conducting cap 2, preventing it from moving and also preventing it from falling off the panel body 1 during use. In addition, because the annular groove 11 is provided and heat-resistant adhesive 4 is filled between the annular groove 11 and the wear-resistant heat-conducting cap 2, the liquid needs to enter the annular groove 11, bypass the inner wall of the wear-resistant heat-conducting cap 2, and then pass through the top surface of the support platform 12 before reaching the receiving hole 13. Therefore, external liquid needs to travel a long path to seep into the receiving hole 13. In addition, the annular groove 11 is filled with heat-resistant adhesive 4, making it extremely difficult for external liquid to seep into the receiving hole 13, thus providing excellent waterproof performance.

[0039] Temperature sensor 3 passes through panel body 1 and abuts against wear-resistant temperature-conducting cap 2, which greatly reduces the distance between temperature sensor 3 and cookware. The heat from the cookware can be transferred to temperature sensor 3 more quickly, effectively improving the temperature sensing speed. During installation, temperature sensor 3 can be inserted upwards from the bottom surface of panel body 1 through receiving hole 13, abutting against wear-resistant temperature-conducting cap 2. Alternatively, temperature sensor 3 and wear-resistant temperature-conducting cap 2 can be bonded and fixed first with heat-resistant adhesive 4, and then both can be fixed together in annular groove 11, with the wire of temperature sensor 3 passing through receiving hole 13 from top to bottom, facilitating connection between temperature sensor 3 and electromagnetic cooker. The other electrical components of the cooking appliance are electrically connected, and the specific installation method is not limited here. As one implementation method, the wear-resistant temperature-conducting cap 2 can be made of metal materials, such as stainless steel, aluminum alloy, or copper alloy. It not only has high thermal conductivity, but also has high strength, good ductility, and wear resistance. Therefore, the wear-resistant temperature-conducting cap 2 only needs to be set to a thin thickness to protect the temperature sensor 3. In the long-term use, it is not easy for the wear-resistant temperature-conducting cap 2 to be worn due to the impact and friction of the cookware, and it can have a longer service life. Of course, the wear-resistant temperature-conducting cap 2 can also be made of engineering plastics, such as PEEK material, which also has good wear resistance. In addition, the top surface of the wear-resistant heat-conducting cap 2 is not lower than the top surface of the panel body 1, which ensures that when the cookware is placed on the rapid temperature-sensing panel, the cookware can effectively contact the wear-resistant heat-conducting cap 2 to achieve temperature sensing. As an optional implementation, the top surface of the wear-resistant heat-conducting cap 2 can be flush with the top surface of the panel body 1, or the top surface of the wear-resistant heat-conducting cap 2 can be higher than the top surface of the panel body 1. Since the cookware is in direct contact with the top surface of the wear-resistant heat-conducting cap 2, the heat of the cookware can be quickly transferred to the temperature sensor 3 through the wear-resistant heat-conducting cap 2. This can both protect the panel and achieve rapid temperature sensing, effectively avoiding the problem of overheating of the panel body 1 due to temperature sensing lag.

[0040] Furthermore, as one embodiment, such as Figure 3-6 As shown, the top surface of the wear-resistant and heat-conducting cap 2 is higher than the top surface of the panel body 1. The upper side wall of the wear-resistant and heat-conducting cap 2 is provided with an inclined transition surface 21. The transition surface 21 makes the part of the wear-resistant and heat-conducting cap 2 that is higher than the top surface of the panel body 1 form a structure that is smaller at the top and larger at the bottom.

[0041] By setting the top surface of the wear-resistant heat-conducting cap 2 to be higher than the top surface of the panel body 1, the wear-resistant heat-conducting cap 2 can support the cookware, so that the cookware and the panel body 1 do not directly contact each other. An air film is formed between the top surface of the cookware and the panel body 1, which can effectively reduce the heat transfer of the cookware to the panel body 1 and reduce the risk of the panel body 1 cracking due to overheating.

[0042] In addition, when the top surface of the wear-resistant thermal conductive cap 2 is higher than the top surface of the panel body 1, a step will be formed at the junction of the wear-resistant thermal conductive cap 2 and the panel body 1, which will make it difficult to clean. Therefore, a transition surface 21 is provided on the upper side wall of the wear-resistant thermal conductive cap 2, so that the upper side wall of the wear-resistant thermal conductive cap 2 forms an inclined straight surface or arc surface. The part of the wear-resistant thermal conductive cap 2 that is higher than the top surface of the panel body 1 forms an obtuse angle or is tangent to the top surface of the panel body 1, so as to reduce the dead corners for hygiene, make it easier for users to clean, and prevent dirt from accumulating.

[0043] Furthermore, the bottom of the transition surface 21 is not lower than the top surface of the panel body 1.

[0044] Understandably, due to machining errors in both the annular groove 11 and the wear-resistant thermally conductive cap 2, it cannot be guaranteed that the bottom of the transition surface 21 will be exactly located in the plane containing the top surface of the panel body 1. Therefore, after the wear-resistant thermally conductive cap 2 and the panel body 1 are assembled, three situations may occur:

[0045] 1. The bottom of the transition surface 21 is higher than the top surface of the panel body 1;

[0046] 2. The bottom of the transition surface 21 is on the same plane as the top surface of the panel body 1;

[0047] 3. The bottom of the transition surface 21 is lower than the top surface of the panel body 1;

[0048] In the third scenario, a groove will be formed between the transition surface 21 and the side wall of the annular groove 11. When soup or water is spilled on the rapid temperature sensing panel, the soup or water will accumulate in the groove, and because the groove is narrow, it will become extremely difficult to clean. In the first scenario, however, no groove will be formed between the transition surface 21 and the side wall of the annular groove 11. This makes the first scenario easier to clean than the third scenario, and soup or water will not accumulate, resulting in a better user experience.

[0049] As another implementation method, such as Figure 2 As shown, the top surface of the support platform 12 is lower than the top surface of the panel body 1, and the top surface of the wear-resistant and heat-conducting cap 2 is flush with the top surface of the panel body 1.

[0050] When the top surface of the wear-resistant temperature-conducting cap 2 is flush with the top surface of the panel body 1, the top surface of the panel body 1 and the top surface of the wear-resistant temperature-conducting cap 2 are treated on the same plane. This allows the top surface of the rapid temperature-sensing panel to form an almost complete plane, making it easier for users to clean the panel after cooking.

[0051] As another implementation method, such as Figure 7 As shown, the top surface of the wear-resistant and heat-conducting cap 2 is provided with a boss 22, and the side wall of the boss 22 forms an obtuse angle or is tangent to the top surface of the wear-resistant and heat-conducting cap 2.

[0052] As another structure of the wear-resistant temperature-conducting cap 2, the wear-resistant temperature-conducting cap 2 is flush with the top surface of the panel body 1. A protrusion 22 is provided on the top of the wear-resistant temperature-conducting cap 2, so that the top surface of the wear-resistant temperature-conducting cap 2 and the top surface of the panel body 1 are on the same plane, making cleaning easier. The protrusion 22 is located on the top surface of the panel body 1, and the side wall of the protrusion 22 and the top surface of the panel body 1 are obtuse angles or tangential transitions, which can avoid the formation of dead corners for hygiene and reduce the difficulty of cleaning. In addition, the protrusion 22 can also support the pot, so that the pot will not come into contact with the panel body 1 during cooking, thereby reducing the heat exposure of the panel body 1 and reducing the requirements for the temperature resistance performance of the panel body 1. Furthermore, supporting the pot by the protrusion 22 can also ensure that the pot can effectively contact the wear-resistant temperature-conducting cap 2, reducing the probability of false readings.

[0053] Furthermore, as an optional implementation, the bottom of the wear-resistant and temperature-conducting cap 2 is provided with a thinning area, and the temperature sensor 3 and the wear-resistant and temperature-conducting cap 2 are abutted against the thinning area.

[0054] To bring the temperature sensor 3 closer to the cookware, a thinned area is provided at the bottom of the wear-resistant heat-conducting cap 2. When installing the temperature sensor 3, simply align the temperature sensor 3 with the thinned area. By further reducing the distance between the temperature sensor 3 and the cookware, the distance the temperature is transferred from the cookware to the temperature sensor 3 is effectively shortened. This allows the temperature sensor 3 to detect the cookware temperature more sensitively, enabling near real-time monitoring of the cookware temperature. This allows for better control of the heat during cooking and timely stopping of heating in case of sudden situations such as dry burning, preventing dangerous situations. It should be noted that for the structure with a boss 22 on the top of the wear-resistant heat-conducting cap 2, the thinned area is located within the area of ​​the boss 22's top view projection. Figure 7As shown, this ensures that the distance between the temperature sensor 3 and the cookware will not increase after the boss 22 supports the cookware.

[0055] Specifically, the thinning area is a receiving groove 23, the top of the receiving groove 23 is an upwardly arched arc surface, and the receiving groove 23 and the receiving hole 13 are both filled with heat-resistant adhesive 4. The temperature sensor 3 is fixed relative to the wear-resistant and heat-conducting cap 2 through the heat-resistant adhesive 4.

[0056] As one way to implement the thinning area, a receiving groove 23 is opened on the bottom surface of the wear-resistant temperature-conducting cap 2. The receiving groove 23 can be formed by stamping or machining. The top of the receiving groove 23 arches upward, so that the thickness of the wear-resistant temperature-conducting cap 2 in the thinning area is gradually changing, that is, a thick-thin-thick structure, similar to the shape of an arch bridge. The advantages of this setting are as follows: First, since the top of the receiving groove 23 is an upward arched structure, during the assembly process, only upward pressure needs to be applied to the temperature sensor 3. The top of the receiving groove 23 can act as a guide, allowing the temperature sensor 3 to slide along the top surface of the receiving groove 23 and abut against the thinnest position of the wear-resistant temperature-conducting cap 2, so that the temperature transmission path is always the shortest, and the rapid temperature sensing performance can be better utilized. Second, although the thickness of the top of the receiving groove 23 is reduced, since the thickness of the top of the receiving groove 23 is continuously changing and arched, it can still have good strength even at the thinnest position, which can effectively protect the temperature sensor 3. The temperature sensor 3 is not easily damaged by the impact of the pot.

[0057] In addition, filling the receiving groove 23 and receiving hole 13 with heat-resistant adhesive 4 can fix the temperature sensor 3, so that the temperature sensor 3 can be fixed relative to the wear-resistant heat-conducting cap 2 after assembly and will not move during use, thus ensuring the temperature sensing effect. In addition, the heat-resistant adhesive 4 can also expel the air between the temperature sensor 3 and the wear-resistant heat-conducting cap 2, so as to avoid affecting the temperature transmission efficiency due to the presence of air between the temperature sensor 3 and the wear-resistant heat-conducting cap 2. It should be noted that the heat-resistant adhesive 4 refers to an adhesive that can meet the usage environment of the rapid temperature sensing panel, such as silicone adhesive, ceramic adhesive, etc., and the composition of the heat-resistant adhesive 4 is not specifically limited.

[0058] Furthermore, the inner wall of the wear-resistant and heat-conducting cap 2 is clearance-fitted with the inner wall of the annular groove 11; the inner top wall of the wear-resistant and heat-conducting cap 2 and / or the top surface of the support platform 12 are provided with protrusions or adhesive grooves.

[0059] This design allows for a certain gap when installing the wear-resistant temperature-conducting cap 2 into the annular groove 11, preventing the need for pressure to install it. Since the panel body 1 is typically made of glass, it is relatively brittle, especially at the edges, and is prone to chipping upon impact. Therefore, the gap fit between the wear-resistant temperature-conducting cap 2 and the annular groove 11 not only makes assembly easier but also protects the edges of the annular groove 11, effectively preventing chipping. The heat-resistant adhesive 4 prevents the wear-resistant temperature-conducting cap 2 from falling out of the annular groove 11 during use, ensuring it is firmly fixed in place. Furthermore, the heat-resistant adhesive 4 also provides waterproofing. When liquid is spilled on the surface of the rapid temperature-sensing panel, the gap between the wear-resistant temperature-conducting cap 2 and the annular groove 11 is filled with the heat-resistant adhesive 4, preventing liquid from seeping into the cooking appliance and thus protecting the internal electrical components and wiring.

[0060] By setting protrusions or adhesive grooves, the bonding area of ​​the wear-resistant heat-conducting cap 2 and / or the annular groove 11 can be increased, thereby improving the bonding force of the wear-resistant heat-conducting cap 2 to the annular groove 11. This allows the heat-resistant adhesive 4 to more firmly bond the wear-resistant heat-conducting cap 2 to the annular groove 11. During long-term use, the wear-resistant heat-conducting cap 2 is less likely to fall out of the annular groove 11, resulting in a longer service life.

[0061] Furthermore, such as Figure 4 , 5 As shown in Figures 7 and 8, the inner wall of the wear-resistant thermally conductive cap 2 gradually slopes outward from top to bottom.

[0062] This design allows the lower part of the wear-resistant thermally conductive cap 2 to be easily aligned with and inserted into the annular groove 11 when it is assembled into the annular groove 11. This effectively reduces the problem of the wear-resistant thermally conductive cap 2 colliding with the top corner of the annular groove 11 and chipping when it is aligned and installed.

[0063] Furthermore, such as Figure 4 , 6 As shown in Figures 7 and 8, the inner wall of the annular groove 11 is an inclined surface, and the upper part of the inner wall of the annular groove 11 is inclined to the side away from the outer wall of the annular groove 11.

[0064] This design allows the sidewalls of the annular groove 11 and the wear-resistant thermally conductive cap 2 to cooperate with each other, thus providing better limiting for the wear-resistant thermally conductive cap 2 and preventing the sidewalls of the annular groove 11 from cracking due to localized stress. In addition, this design allows the corner sections of the annular groove 11 to be obtuse, which increases the strength of the top corners of the annular groove 11 and further prevents edge chipping.

[0065] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way.
