Description

Technical Field

[0001] This utility model relates to the field of barbecue technology, and in particular to a handle structure that can effectively reduce temperature. Background Technology

[0002] The top cover of a barbecue grill is one of its core components. Its curved or concave design guides hot air circulation, preventing localized overheating or scorching, which keeps the top cover at a high temperature during use. To facilitate opening the top cover, a handle is usually provided.

[0003] Taking a charcoal grill as an example, when the charcoal is burning continuously, the temperature of the top cover can easily exceed 300℃. Handles can be categorized by material: metal handles, bakelite handles, and rubber handles. If a metal handle is used to connect to the top cover, the heat from the top cover will be quickly conducted to the handle due to metal's excellent heat conductor properties, causing the handle temperature to rise and potentially resulting in burns. To solve this problem, handles are usually designed with a hollow structure. Compared to a solid structure, a hollow structure reduces the volume of heat-conducting material, resulting in less material that heat needs to pass through, thus reducing the total amount of heat conduction and lowering the handle temperature.

[0004] However, hollow handles typically need to be secured to the top cover using metal screws, clips, or welds. These metal components create highly efficient heat conduction channels, causing heat to be transferred directly from the top cover to the handle surface through these highly thermally conductive parts. When the top cover becomes too hot, it can still cause burns. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that can cause burns, and to propose a handle structure that can effectively reduce temperature.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a handle structure that can effectively reduce temperature, including a grip portion, both ends of which are fixedly connected to threaded sleeves, each of the two threaded sleeves is threadedly connected to a threaded post, each of the two threaded posts is threadedly connected to a nut, and multiple welded parts are fixedly connected at equal intervals on the sides of the two nuts, the multiple welded parts are fixedly connected to the inner wall of a hollow tube, the nut is located inside the hollow tube, and the nut and the hollow tube are connected by a heat insulation mechanism, and both hollow tubes are connected to a top cover by a fixing mechanism.

[0008] Preferably, the hollow tube is a stainless steel tube.

[0009] Preferably, the heat insulation mechanism includes a mica heat insulation layer, which is fixedly connected to the nut. A ceramic gasket is fixedly connected to the lower end of the mica heat insulation layer. The ceramic gasket abuts against the lower surface of the nut and is coaxially arranged with the nut.

[0010] Preferably, a support shell is fixedly connected to the inner wall of the hollow tube, and the support shell is used to support the ceramic gasket.

[0011] Preferably, a mica heat insulation gasket is fixedly connected to the upper end of the hollow tube, and the mica heat insulation gasket abuts against the threaded sleeve.

[0012] Preferably, the length of the hollow tube is greater than 15cm.

[0013] Preferably, the fixing mechanism includes a bottom cover, which is fixedly connected to the lower end of the hollow tube. A rivet nut is fixedly connected to the bottom cover, and a screw is threaded onto the rivet nut, with the screw penetrating through the top cover.

[0014] Preferably, the gripping part is coated with a Teflon coating.

[0015] The present invention proposes a handle structure that can effectively reduce temperature. The beneficial effects are as follows: the nut is spot-welded with multiple welding parts, which reduces the effective heat transfer area and the total amount of heat conduction. At the same time, the heat insulation mechanism plays a role in isolating heat and reducing the conduction efficiency of the heat conduction path, thereby reducing the temperature of the handle and preventing burns when gripping it.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-4 A handle structure that can effectively reduce temperature includes a grip portion 1, with threaded sleeves 9 fixedly connected to both ends of the grip portion 1. Threaded posts 8 are threadedly connected to the two threaded sleeves 9, and nuts 3 are threadedly connected to the two threaded posts 8. Multiple welded parts 12 are fixedly connected at equal intervals on the sides of the two nuts 3. The multiple welded parts 12 are fixedly connected to the inner wall of a hollow tube 7. The fixed connection is achieved by welding, which welds the multiple welded parts 12 to the inner wall of the hollow tube 7, thus spot welding the nuts 3 instead of large-area welding, reducing the effective heat transfer area and the total amount of heat conduction. At the same time, the nuts 3 are threadedly connected to the threaded posts 8 to facilitate disassembly of the grip portion 1 and the hollow tube 7, so that the parts can be replaced if one of them is damaged.

[0023] Nut 3 is located inside hollow tube 7. Hollow tube 7 reduces the volume of heat conduction, thereby reducing the total amount of heat conduction. Hollow tube 7 is made of stainless steel, which prevents rust from forming.

[0024] A heat insulation mechanism is used between the nut 3 and the hollow tube 7. Both hollow tubes 7 are connected to the top cover 2 through a fixing mechanism. The heat insulation mechanism includes a mica heat insulation layer 14, which is fixedly connected to the nut 3. A ceramic gasket 10 is fixedly connected to the lower end of the mica heat insulation layer 14. The ceramic gasket 10 abuts against the lower surface of the nut 3 and is coaxially arranged with the nut 3. By using the mica heat insulation layer 14, the heat conduction path between the nut 3 and the hollow tube 7 is blocked, preventing the heat of the hollow tube 7 from being transferred to the nut 3 through heat radiation, thereby further reducing heat transfer.

[0025] A support shell 13 is fixedly connected to the inner wall of the hollow tube 7. The support shell 13 is used to support the ceramic gasket 10. By using the ceramic gasket 10, the heat of the hollow tube 7 is prevented from being transferred to the nut 3 through the support shell 13. The support shell 13 is set to support the nut 3 and facilitate spot welding of the nut 3.

[0026] A mica heat insulation pad 11 is fixedly connected to the upper end of the hollow tube 7. The mica heat insulation pad 11 abuts against the threaded sleeve 9. The mica heat insulation pad 11 acts as a barrier to the heat transfer between the hollow tube 7 and the threaded sleeve 9, thereby reducing the amount of heat transferred.

[0027] The fixing mechanism includes a bottom cover 6, which is fixedly connected to the lower end of the hollow tube 7. A rivet nut 4 is fixedly connected to the bottom cover 6, and a screw 5 is threaded onto the rivet nut 4. The screw 5 passes through the top cover 2, and the top cover 2 and the bottom cover 6 are fixedly connected by the screw 5. A handle is installed on the top cover 2. A rubber sealing ring is fitted on the screw 5, and a ceramic heat insulation layer is sprayed on the rubber sealing ring. The rubber sealing ring abuts against the top cover 2 to seal, preventing high-temperature flue gas from flowing out from the gap between the screw 5 and the top cover 2.

[0028] During heat transfer, screw 5 transfers heat to rivet nut 4, rivet nut 4 transfers heat to bottom cover 6, bottom cover 6 transfers heat to hollow tube 7, and the heat on hollow tube 7 is transferred to grip part 1 through two paths. Path 1: After heat is insulated by mica heat insulation gasket 11 through hollow tube 7, it is transferred to grip part 1. Path 2: Hollow tube 7 passes through welded part 12, which reduces the heat transfer area and the total amount of heat conduction, and the reduced heat is transferred to nut 3. Nut 3 transfers heat to threaded post 8, and finally to grip part 1.

[0029] Example 2: Refer to Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 1, the length of the hollow tube 7 is greater than 15cm, which keeps the hands away from the high-temperature area, avoids direct contact with the barbecue grill, and is also conducive to the safety of operation.

[0030] Example 3: Reference Figure 1-2 As another preferred embodiment of this utility model, based on embodiment 2, the grip part 1 is coated with a Teflon coating. When grilling, the hands are easily stained with oil, which will also leave oil stains on the grip part 1. The ultra-low coefficient of friction of the Teflon coating helps to prevent oil stains from adhering to the grip part 1, making it easier to clean the oil stains on the grip part 1.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
