Description

Technical Field

[0001] The utility model relates to the technical field of glass heating kettles, in particular to a safe and reliable glass heating kettle and a health-preserving kettle using the same. Background Art

[0002] This section only provides background information related to the present application to help those skilled in the art understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] The bottom of the kettle body in the traditional heating kettle is a stainless steel plate. Since the stainless steel plate has good thermal conductivity, when the water in the kettle body is heated to boiling through the stainless steel plate, the heating plate at the bottom of the stainless steel plate is still at a relatively low working temperature; when the kettle body lacks water and starts to dry-heat, the temperature of the stainless steel plate and the heating plate will rise sharply. Therefore, by setting a dry-heating plate and a temperature fuse on the heating plate, when the set working temperature is exceeded, the dry-heating plate or the temperature fuse can cut off the power supply of the heating plate in time to ensure the safety of the product.

[0004] However, stainless steel plates are prone to produce metal ions and harmful substances during the heating process, which have a certain impact on human health, so all-glass heating kettles are gradually becoming popular. Most of the existing all-glass heating kettles have a microcrystalline glass plate at the bottom of the kettle body. Due to the poor thermal conductivity of the microcrystalline glass plate, when the water in the kettle body is heated to boiling through the microcrystalline glass plate, the heating plate at the bottom of the microcrystalline glass plate is already at a high operating temperature, which exceeds the limit operating temperature of the dry-burning plate and the temperature fuse. Therefore, the dry-burning plate and the temperature fuse cannot be set on the heating plate, and the safety of the product cannot be guaranteed. Utility Model Content

[0039] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the modules or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0042] See also Figure 1-6 The utility model provides a safe and reliable glass heating kettle, comprising a full glass kettle body 1, a heating component and an upper coupler 4, the full glass kettle body 1 comprising a glass kettle body 11 and a microcrystalline glass plate 12 arranged at the bottom opening of the glass kettle body 11; the heating component comprises a heating disk 2 arranged at the bottom of the microcrystalline glass plate 12 and a heat insulation cover 3 arranged below the heating disk 2 and connected thereto, the heating disk 2 comprises a heat transfer plate 21 fitted with the bottom surface of the microcrystalline glass plate 12 and a heating tube 22 arranged at the bottom of the heat transfer plate 21; the upper coupler 4 is arranged at the bottom of the heat insulation cover 3 and comprises a seat body 41 and a bracket 42 arranged on the seat body 41, a temperature fuse 431 and a dry-burning sheet 441 which are electrically conductive with the heating tube 22 are arranged on the bracket 42, the temperature fuse 431 and the dry-burning sheet 441 are both fitted with the heat insulation cover 3 to achieve heat conduction.

[0043] Therefore, by connecting the heat insulation cover 3 with the heating plate 2 and fitting the dry-burning sheet 441 and the temperature fuse 431 with the heat insulation cover 3, since the temperature of the heat insulation cover 3 is relatively low, the normal use of the dry-burning sheet 441 and the temperature fuse 431 can be guaranteed. When the temperature of the dry-burning sheet 441 or the temperature fuse 431 exceeds the rated working temperature, the dry-burning sheet 441 and the temperature fuse 431 can be activated and the heating plate 2 can be powered off, thereby ensuring the safety of the product and improving the reliability of the product.

[0044] In this embodiment, a mounting column is provided at the bottom of the heat transfer plate 21, and a mounting hole corresponding to the mounting column is provided on the fixing ring 7. The mounting column and the mounting hole are connected and fixed by bolts.

[0045] In this embodiment, a ring-shaped fixing ring 7 is provided at the bottom of the glass pot body 11 , and a plurality of brackets 8 are provided on the fixing ring 7 . The brackets 8 are connected to the heat insulation cover 3 so as to fix the heat insulation cover 3 on the glass pot body 11 .

[0046] See also Figure 3-4, also includes an L-pole conductive ring 461, an N-pole conductive ring 462, an L-pole terminal piece 451 and an N-pole terminal piece 452 arranged on the base body 41, and the L-pole terminal piece 451 and the N-pole terminal piece 452 are both electrically connected to the heating tube 22; the L-pole conductive ring 461 and the L-pole terminal piece 451 are electrically connected through a first conductive component, and the N-pole conductive ring 462 and the N-pole terminal piece 452 are electrically connected through a second conductive component; specifically, the first conductive component includes a temperature fuse 431, a first conductive sheet 433 and a first porcelain column 432 inserted on the first conductive sheet 433, one end of the first conductive sheet 433 contacts with the L-pole conductive ring 461 and conducts electricity; the second conductive component includes a dry-burning sheet 441, a second conductive sheet 443 and a second porcelain column 442 inserted on the second conductive sheet 443, one end of the second conductive sheet 443 contacts with the N-pole conductive ring 462 and conducts electricity.

[0047] Thus, when the temperature fuse 431 is in a normal state, the temperature fuse 431 abuts the first ceramic column 432 and drives the other end of the first conductive sheet 433 to contact the L terminal sheet 451 to achieve electrical conduction; when the temperature fuse 431 is subjected to a high temperature and melted by heat, the first ceramic column 432 resets and drives the other end of the first conductive sheet 433 to separate from the L terminal sheet 451, thereby disconnecting the circuit; similarly, when the dry-burning sheet 441 is in a normal state, the dry-burning sheet 441 abuts the second ceramic column 442 and drives the other end of the second conductive sheet 443 to contact the N terminal sheet 452 to achieve electrical conduction; when the dry-burning sheet 441 is subjected to a high temperature and deformed, the second ceramic column 442 resets and drives the other end of the second conductive sheet 443 to separate from the N terminal sheet 452, thereby disconnecting the circuit. When the temperature drops to a normal value, the dry-burning sheet 441 returns to its original state and the circuit is turned on again.

[0048] Therefore, by setting the temperature fuse 431 and the dry-burning sheet 441 on the bracket 42, when the temperature exceeds the rated working temperature, the temperature fuse 431 can be melted or the dry-burning sheet 441 can be deformed, thereby disconnecting the circuit to avoid safety accidents.

Preferably, the NTC temperature probe 5 is fixed to the heat insulation cover 3 via a mounting plate.

[0050] Therefore, by arranging the NTC temperature probe 5 on the heat insulation cover 3 and making it in direct contact with the heating tube 22, when the kettle body is dry-burning due to lack of water, the NTC temperature probe 5 can accurately monitor the temperature change of the heating tube 22 and send a signal to the control component, thereby reducing the power of the heating tube 22 to prevent the temperature of the heating tube 22 from being too high and affecting the safety and life of the product.

[0051] See also Figure 3-4 , and also includes a signal input conductive ring 463, a signal output conductive ring 464, a signal input terminal piece 453 and a signal output terminal piece 454 arranged on the base body 41.

[0056] (I) The glass heating kettle of the utility model connects the heat insulation cover 3 with the heating plate 2 and fits the dry-burning sheet 441 and the temperature fuse 431 with the heat insulation cover 3.
