Description

Technical Field

[0001] The utility model relates to the field of flower teapots, in particular to a flower teapot. Background Art

[0002] Current heating devices, such as electric kettles and electric water cups, primarily use cast aluminum heating plates and electromagnetic heating to heat containers. The cast aluminum heating plate primarily consists of a heating tube and an aluminum casting, which is wrapped around the heating tube. The heating tube includes a heating wire and a metal outer tube, which is wrapped around the heating wire and filled with insulating thermally conductive materials such as magnesium oxide powder between the metal outer tube and the heating wire. Heat from the heating wire passes through the insulating thermally conductive material and the metal outer tube before being transferred to the aluminum casting, resulting in significant heat loss and high costs. Furthermore, because the heating plate uses contact heating, it requires good contact with the bottom of the vessel. However, the molding process for glassware and ceramic vessels is difficult to maintain consistency during production, making it difficult to ensure a reliable fit between the bottom shape and the heating plate, resulting in low heating efficiency.

[0003] Electromagnetic heating mainly consists of an electromagnetic heating control circuit, a copper coil, a heat dissipation fan, etc. Moreover, glass or ceramic containers cannot be heated directly, and a magnetic induction heating coating needs to be provided on the bottom of the container, which is more expensive and more difficult to process. In addition, the above heating method is large in size and not light enough, which is not conducive to use in portable heating devices.

[0004] Therefore, the applicant submitted a patent application on July 20, 2024, with the subject name of a flower teapot and its heating device, and the application number is: CN202421731473.4. This radiant heating plate effectively solves the above problems, but the mica winding board in the radiant heating plate covers the entire mica substrate, causing the edges of the radiant heating plate to also generate uniform high temperatures. When the radiant heating plate is installed on the heating device, this situation makes the installation of the radiant heating plate difficult, and the edge of the mica winding board is too close to the heating device, and the high temperature will be quickly transferred to the heating device, causing its outer surface temperature to be high enough, so further improvement is needed.

[0043] This flower teapot uses a radiation heating plate 1 of this structure. Compared with the previous existing technology, it adds a low-temperature edge area X with a certain width, which can effectively reduce the temperature of the edge of the radiation heating plate 1, facilitate the installation and fixation of the radiation heating plate 1, reduce the difficulty of installation, and form an insulating distance between the area of ​​the mica winding plate 12 and the flower teapot, reducing heat transfer to the flower teapot.

[0045] Specifically, a groove 123 is provided on one side of the two adjacent mica winding plates 12 , thereby enlarging the interval between the heating wires 11 of the two mica winding plates 12 .

[0046] See also Figure 8 and Figure 9 As shown, a plurality of tooth grooves 122 are provided on the edges of the mica winding plate 12 , and the heating wire 11 is wound through the tooth grooves 122 ; the tooth grooves 122 can stabilize the intervals between the sections of the heating wire 11 .

[0049] In addition, in this embodiment, the electrode 14 is disposed on a side of the mica substrate 13 facing away from the mica winding plate 12 .

[0050] The mica winding plate 12 and the mica base plate 13 are connected and fixed by rivets 15 .

[0051] This radiation heating plate 1 is applied to a flower teapot. A radiation heating area is formed above the base 2 of the flower teapot corresponding to the radiation heating plate 1, which can radiate heat to any glass pot body 3 and can also heat other ceramic utensils.

[0052] See also Figure 10 As shown, the glass pot body 3 includes a cup-shaped glass pot body 31, and a cup cover 32 is provided on the top. The cup cover 32 and the glass pot body 31 form a heating cavity, and a filter vessel 33 or a stewing vessel 34 is provided in the heating cavity.

The protective cover 8 also has high temperature characteristics, which serves the purpose of multi-layer heat insulation.

[0057] In other embodiments, a cooling fan is further included, and the cooling fan is arranged in the base 2 corresponding to the cooling holes 201; when the cooling holes 201 of the radiation heating plate 1 alone lead to insufficient cooling efficiency, a cooling fan can be added to improve efficiency and speed.

However, due to the shielding of the heat by the mica winding plate 12 and the mica substrate 13, this part of the heat can only be wasted. Therefore, through the heat-transmitting through holes 121, the heat generated by the heating wires 11 on the lower surface can pass through the heat-transmitting through holes 121 and radiate upward, thereby improving the heating efficiency of the radiation heating plate 1 and reducing energy waste.
