Description

Technical Field

[0001] The utility model mainly relates to the technical field of heating cups, and particularly relates to a double-layer heating cup. Background Technique

[0002] With the increasing improvement of the scientific and technological level, the application of heating cups is becoming more and more extensive. In addition to boiling water, heating cups can also make coffee, milk, instant noodles, etc. They integrate the functions of ordinary cups and electric kettles, are very convenient and fast, and fully adapt to the fast-paced living habits of most people in today's society.

[0003] However, when the existing heating cup is heating, the cup body is easy to separate from the heating base, which may easily cause scalding to people if not noticed. And because the heating base needs to be in contact with the cup body, the bottom of the cup body cannot be made into a vacuum, resulting in faster heat dissipation of the heating cup. There is a need for a new type of double-layer heating cup. Summary of the Utility Model

[0004] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution significantly different from the existing technology. It mainly provides a double-layer heating cup to solve the technical problems of easy separation between the cup body and the heating base and the inability to make the bottom of the cup body into a vacuum, resulting in faster heat dissipation of the heating cup as mentioned in the above background technique.

[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0006] A double-layer heating cup, including a base and a cup body. A cylinder is installed at the center of the upper surface of the base. A heating resistor is installed inside the cylinder.

[0024] Please refer specifically to the attached Figures 1-4 , a double-layer heating cup, comprising a base 1 and a cup body 4. A cylinder 12 is installed at the center of the upper surface of the base 1. A heating resistor 2 is installed inside the cylinder 12. A first ring 3 is installed at the bottom of the cup body 4. The first ring 3 is sleeved on the annular surface of the cylinder 12 and is in contact with the base 1. An annular groove is opened in the first ring 3. An annular plate 6 is rotatably connected in the annular groove. The annular plate 6 is made of heat-insulating material. A second ring 5 installed at the bottom of the cup body 4 is slidably connected inside the annular plate 6. The second ring 5 is inserted into the cylinder 12.

[0025] A plurality of arc-shaped plates 8 are arranged on the side of the second ring 5 away from the bottom of the cup. The arc-shaped plates 8 are made of heat-insulating material and the plurality of arc-shaped plates 8 are in contact with each other. A plurality of first rotating rods 9 arranged annularly and equidistantly are installed on the lower surface of the second ring 5. The first rotating rods 9 are rotatably connected to the arc-shaped plates 8. Cross-section L-shaped fixing rods 15 are installed on the sides of the plurality of arc-shaped plates 8 facing away from each other. Then, a plurality of spiral grooves 14 gradually extending inward are opened on the upper surface of the cylinder 12. The round rod 7 is in rotational contact with the spiral grooves 14.

[0026] Second rotating rods 10 are installed on the lower surfaces of the annular plate 6 and the arc-shaped plate 8, wherein the number of second rotating rods 10 on the annular plate 6 is consistent with the number of arc-shaped plates 8, and a plurality of connecting plates 11 are arranged between the arc-shaped plate 8 and the annular plate 6, and the two ends of the connecting plate 11 are rotatably connected to the second rotating rod 10 on the arc-shaped plate 8 and the second rotating rod 10 on the adjacent annular plate 6 respectively.

[0027] The bottom of the cup body 4 is sealed by the arc plate 8 to prevent the heat in the cup body 4 from being lost through the bottom. At the same time, when the annular plate 6 is rotated, the arc plate 8 can be driven to rotate to the side away from each other, so that the fixing rod 15 is inserted into the annular groove, thereby realizing the connection between the arc plate 8 and the base 1, thereby preventing the cup body 4 from being separated from the base 1.

[0028] A plurality of circular holes 13 are formed on the upper surface of the circular ring, and a plurality of circular rods 7 are mounted on the lower surface of the circular plate 6 . One end of the circular rod 7 away from the circular plate 6 is inserted into the circular hole 13 .

[0029] In order to facilitate the first ring 3 to be sleeved on the annular surface of the ring, an annular bevel is cut on the upper side of the annular surface of the cylinder 12.

[0030] The specific operation process of the utility model is as follows: align the round rod 7 with the round hole 13, then insert the first ring 3 into the cylinder 12, and then rotate the cup body 4, use the round rod 7 to limit the annular plate 6, and then the cup body 4 rotates to drive the first ring 3 and the second ring 5 to rotate without driving the annular plate 6 to rotate, and because the second ring 5 is rotatably connected with the arc plate 8 through the first rotating rod 9, when the second ring 5 rotates, the position of the first rotating rod 9 is driven to change, but the second rotating rod 10 installed on the first annular plate 6 will not rotate synchronously, resulting in a change in the distance between the first rotating rod 9 and the second rotating rod 10, thereby causing the arc plate 8 to rotate with the first rotating rod 9 as the center, thereby opening the second ring 5, and at this time the heating resistor 2 can be inserted into the second ring 5 and contact the bottom of the cup body 4, and then the heating resistor 2 switch can be turned on for heating, and when the arc plate 8 is opened, the fixing rod 15 is inserted into the spiral groove 14 in a spiral form to fix the cup body 4 to the base 1.

[0031] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
