[0035] See also Figure 1-5 The utility model provides an anti-dry-burning water bottle, comprising an inner liner 1, a heating plate 2 arranged at the bottom of the inner liner 1 to heat it, and a coupler 3 arranged at the bottom of the heating plate 2; wherein the heating plate 2 comprises a heat transfer plate 21 fitted with the bottom surface of the inner liner 1 and a heating tube 22 arranged at the bottom of the heat transfer plate 21; the coupler 3 comprises a seat 31 and a cover plate 32 arranged on the seat 31, and a first dry-burning sheet 341, a second dry-burning sheet 342 and a fuse 343 which are electrically conductive with the heating tube 22 are installed on the cover plate 32, and the first dry-burning sheet 341, the second dry-burning sheet 342 and the fuse 343 are all fitted with the lower end surface of the heat transfer plate 21 to achieve heat conduction. wherein the first dry-burning sheet 341 and the second dry-burning sheet 342 are respectively located on the left and right sides of the lower end surface of the heat transfer plate 21.

[0036] Therefore, by arranging the first dry-burning sheet 341 and the second dry-burning sheet 342 on the coupler 3, and the first dry-burning sheet 341 and the second dry-burning sheet 342 are respectively attached to the left and right sides of the lower end surface of the heat transfer plate 21, such an arrangement can prevent the inner tank 1 from tilting and causing dry burning on one side of the inner tank 1, thereby improving the success rate of preventing dry burning and reducing the probability of the fuse 343 melting.

[0037] See also Figure 3-5 Furthermore, the coupler 3 also includes an L-pole conductive circuit and an N-pole conductive circuit which are arranged on the seat body 31 and electrically connected to the heating tube 22, wherein a first porcelain column 381 is movably arranged between the first dry-burning sheet 341 and the L-pole conductive circuit, and a second porcelain column 382 is movably arranged between the second dry-burning sheet 342 and the N-pole conductive circuit. When the temperature on the first dry-burning sheet 341 and / or the second dry-burning sheet 342 exceeds the rated working temperature, the first dry-burning sheet 341 and / or the second dry-burning sheet 342 are deformed and drive the first porcelain column 381 and / or the second porcelain column 382 to disconnect the L-pole conductive circuit and / or the N-pole conductive circuit, thereby disconnecting the heating tube 22 to prevent the inner tank 1 from continuing to heat.

[0038] Specifically, the L-pole conductive circuit includes an L-pole terminal sheet 361 and a first conductive sheet 362, one end of the L-pole terminal sheet 361 contacts the heating tube 22 and conducts electricity, the other end of the L-pole terminal sheet 361 contacts one end of the first conductive sheet 362 and conducts electricity, the bottom of the first porcelain column 381 is passed through the other end of the first conductive sheet 362, and the top of the first porcelain column 381 is in conflict with the first dry-burning sheet 341; when the temperature of the first dry-burning sheet 341 exceeds the rated operating temperature and deforms, it can drive the first porcelain column 381 to move downward so that one end of the first conductive sheet 362 is lifted up and separated from the L-pole terminal sheet 361 to disconnect the L-pole conductive circuit. Similarly, the N-pole conductive circuit includes an N-pole terminal sheet 371 and a second conductive sheet 372. One end of the N-pole terminal sheet 371 contacts the heating tube 22 and conducts electricity, and the other end of the N-pole terminal sheet 371 contacts one end of the second conductive sheet 372 and conducts electricity.

[0040] Furthermore, a third porcelain column 383 is movably arranged between the fuse 343 and the N-pole conductive circuit, the bottom of the third porcelain column 383 is passed through the second conductive sheet 372, and the top of the third porcelain column 383 is in conflict with the fuse 343; when the temperature of the fuse 343 exceeds the rated operating temperature and melts, the third porcelain column 383 moves upward under the action of elastic force and drives the second conductive sheet 372 to move upward and separate from the N-pole terminal sheet 371 to disconnect the N-pole conductive circuit.

[0041] Therefore, by setting the fuse 343, a last line of defense is reserved for the anti-dry-burn protection of the kettle, thereby ensuring the safety of the product and meeting the safety requirements.

[0042] Of course, in other embodiments, the fuse 343 may also be set on the L-pole conductive circuit, that is, the third porcelain column 383 may be movably set between the fuse 343 and the L-pole conductive circuit, which can also achieve the effect of disconnecting the heating tube 22; or, two third porcelain columns 383 are set and used to disconnect the L-pole conductive circuit and the N-pole conductive circuit respectively, which is not limited here.

[0043] Furthermore, it also includes a first guide bracket 351 and a second guide bracket 352 arranged in the base body 31, the first guide bracket 351 is provided with a first guide hole 3511 for the first porcelain column 381 to pass through and guide its up and down movement, the second guide bracket 352 is provided with a second guide hole 3521 for the second porcelain column 382 to pass through and guide its up and down movement, and a third guide hole 3522 for the third porcelain column 383 to pass through and guide its up and down movement.

[0044] Therefore, by providing the first guide bracket 351 and the second guide bracket 352, it is possible to ensure that the first porcelain column 381, the second porcelain column 382 and the third porcelain column 383 can slide up and down stably, thereby reducing the possibility of failure of the anti-dry burning action caused by the tilt and displacement of the porcelain columns.

[0045] Furthermore, the coupler 3 further comprises a connection bracket 33 connected to the base body 31, and the connection bracket 33 is detachably connected and fixed to the heat transfer plate 21. Specifically, a plurality of mounting posts 211 are convexly provided on the lower end surface of the heat transfer plate 21, and a plurality of mounting holes 331 corresponding to the plurality of mounting posts 211 are provided on the connection bracket 33; thus, the connection bracket 33 can be connected and fixed to the heat transfer plate 21 by passing a fastener through the mounting hole 331 and fixing it in the mounting post 211. Preferably, the mounting hole 331 is a through hole, the mounting post 211 is a nut post, and the fastener is a locking screw.
