Description

Technical Field

[0001] The utility model relates to the technical field of heating coasters, and particularly relates to a heating coaster with an infrared induction device. Background Art

[0002] A heating coaster, also known as a heat-preserving coaster, is a coaster that continuously heats and keeps warm a cup body through a heating element, and is applicable to living environments such as offices and homes. Existing heating coasters usually only have a heating function. If the cup body is moved away from the heating coaster during use, the heating coaster will still continue to heat, which not only consumes electric energy in such a state but also easily causes users to be accidentally scalded by touching, or the cup body is still heated when there is no liquid in the cup body, resulting in the cup body being dry-burned and cracked. Therefore, it is necessary to improve the heating coaster. Summary of the Utility Model

[0006] Specifically, the upper end of the coaster upper cover is provided with a first induction position and a second induction position arranged oppositely. The infrared induction device includes an infrared emission end and an infrared reception end. The infrared emission end is arranged at the first induction position, and the infrared reception end is arranged at the second induction position.

[0007] Specifically, a first boss protruding upward is provided at the front end of the coaster upper cover. A touch panel is arranged on the upper surface of the first boss, and the first induction position is formed at the rear side of the first boss.

[0008] Specifically, a second boss protruding upward is provided at the rear end of the coaster upper cover. The volume of the second boss is smaller than that of the first boss, and the second induction position is formed at the front side of the second boss.

[0009] Specifically, the upper surface of the first boss is inclined upward.

[0021] As Figures 1 to 4 shown, a heating coaster with an infrared sensing device includes a coaster body 10. A heating area 11 is provided on the coaster body 10, and a heating element 12 is arranged at the heating area 11. An infrared sensing device is also provided above the coaster body 10. The infrared sensing device is arranged adjacent to the heating area 11 and is connected to the heating element 12 for controlling the on or off of the heating element 12. When using the heating coaster, by arranging the infrared sensing device on the coaster body 10, the position of the cup located in the heating area 11 and the water volume in the cup are sensed by the infrared sensing device, so as to facilitate controlling the start or stop of the heating element 12, thereby avoiding the heating area 11 still being in a heating state and scalding the user when not in use, or continuing to heat when the water volume in the cup is low and causing a dry burning phenomenon, so as to improve the user experience.

[0022] The coaster body 10 includes a coaster base 13. The coaster base 13 is provided with an installation groove 14 with an upward opening. A coaster upper cover 15 is covered on the installation groove 14. The heating element 12 is arranged in the installation groove 14, and the heating area 11 is formed in the middle of the coaster upper cover 15. In this embodiment, the installation groove 14 is arranged on the coaster base 13, which facilitates the installation of the heating element 12. At the same time, the heating area 11 is arranged on the coaster upper cover 15, which facilitates the placement and heating of an external cup.

[0023] The upper end of the upper cover 15 of the coaster is provided with a first induction position 16 and a second induction position 17 which are oppositely arranged. The infrared induction device includes an infrared emission end and an infrared reception end. The infrared emission end is arranged on the first induction position 16, and the infrared reception end is arranged on the second induction position 17. In this embodiment, the first induction position 16 and the second induction position 17 which are oppositely arranged are set on the upper cover 15 of the coaster. By setting the infrared emission end on the first induction position 16 and then setting the infrared reception end on the second induction position 17, the emission and reception of infrared rays are realized. When the cup body is placed in the heating area 11, the infrared rays will be refracted at a certain angle due to the influence of the cup body. When there is liquid in the cup body, the relevant refraction angle will further change. Thus, it can be judged whether there is a cup body in the heating area 11 and whether there is liquid in the cup body through the infrared rays emitted between the infrared emission end and the infrared reception end, and then the control of the heating element 12 is realized.

[0024] A first boss 18 protruding upward is arranged at the front end of the upper cover 15 of the coaster. The upper surface of the first boss 18 is provided with a touch panel 22, and the first induction position 16 is formed at the rear side of the first boss 18; a second boss 19 protruding upward is arranged at the rear end of the upper cover 15 of the coaster. The volume of the second boss 19 is smaller than that of the first boss 18, and the second induction position 17 is formed at the front side of the second boss 19; the upper surface of the first boss 18 is inclined upward. In this embodiment, the first boss 18 is arranged at the front end of the upper cover 15 of the coaster, and the second boss 19 is arranged at the rear end of the upper cover 15 of the coaster. The first induction position 16 and the second induction position 17 are respectively formed on the opposite side surfaces of the first boss 18 and the second boss 19, which is convenient for the installation of the infrared emission end and the infrared reception end, improves the installation efficiency. At the same time, the touch panel 22 is inclined on the upper surface of the first boss 18, which is convenient for manually regulating the heating element 12 through the touch panel 22.

[0025] Heat dissipation holes 20 are arranged below the coaster base 13, and the heat dissipation holes 20 are communicated with the installation groove 14. In this embodiment, the heat dissipation holes 20 are arranged below the coaster base 13. The heating element 12 can be dissipated heat through the heat dissipation holes 20, thereby avoiding overheating of the temperature in the installation groove 14.

[0026] The lower surface of the coaster base 13 is rectangular, and anti-slip protrusions 21 are arranged at the corners of the lower surface. In this embodiment, the anti-slip protrusions 21 are arranged on the lower surface of the coaster base 13. The anti-slip support for the coaster body 10 when placed on a plane is facilitated through the anti-slip protrusions 21.

[0027] The above are only the preferred embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
