Description

Technical Field

[0001] The utility model relates to the technical field of kettles, in particular to a self-heating kettle. Background Art

[0002] The electric kettle is an indispensable small household appliance in daily life. It heats up quickly and it usually only takes a few minutes to boil a pot of water. It is an energy-saving and electricity-saving fast heating appliance. In addition, the electric kettle is easy to use and automatically cuts off the power when the water boils, ensuring safety during use.

[0003] An electric kettle is a device that uses electrical energy to convert into thermal energy to heat water. The working principle of an electric kettle is that the steam generated when water boils causes the bimetallic strip of the steam temperature sensing element to deform. This deformation pushes the power switch to cut off the power through the lever principle.

[0004] A search revealed a safety kettle with patent publication number CN221577469U that proposes "a two-way backflow valve is provided, and the heating base heats the water in the kettle. Some of the overflow water generated during the heating process enters the two-way backflow valve through a first overflow port, and some enters the water storage tank through a second overflow port before flowing into the two-way backflow valve. From the two-way backflow valve, it flows into the guide pipe, then into the heating base through a first drain hole, and finally discharged through a second drain hole, thereby preventing water from spraying out of the spout and causing burns to the operator, providing good protection."

[0005] However, the above solution still has certain shortcomings in actual use. The heating base is not provided with a protective structure when heating the kettle, resulting in external collisions causing the heating base to separate from the kettle, and the heating base will still retain a certain amount of heat after the heating is completed, resulting in poor safety of the heating base at this time, thereby affecting the stability of the kettle.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model discloses a self-heating kettle, comprising a kettle structure 1 and a protective heating structure 2. A control panel 3 is provided on the outer side of the protective heating structure 2, and the control panel 3 is electrically connected to the protective heating structure 2.

[0023] The kettle structure 1 includes a kettle body 101, the bottom end of the kettle body 101 is interconnected with the heating plate 203, a handle 102 is fixedly installed on the outside of the kettle body 101, a water outlet 103 is provided on the surface of the kettle body 101, a spout 104 is provided on the outside of the water outlet 103, a top cover 105 is movably connected to the top of the kettle body 101, a water inlet 106 is provided inside the top cover 105, and a flip cover 107 is hinged on the top of the top cover 105.

[0024] The protective heating structure 2 includes a placement base 201 , a placement platform 202 is movably connected to the top of the placement base 201 , and a heating plate 203 is provided on the top of the placement platform 202 .

[0025] The inner wall of the placement base 201 is connected to a driving gear 204 through a built-in motor. Two follower racks 205 are engaged on the outer side of the drive gear 204. An external plate 209 is fixedly installed on the outer side of the follower rack 205. A bending rod 210 is fixedly installed on the top of the external plate 209. The top ends of the two bending rods 210 are respectively fixedly connected to a heat dissipation cover 211 and a guardrail 212. A fan is provided inside the heat dissipation cover 211.

[0026] By setting up a protective heating structure 2, before the heating disk 203 heats the kettle structure 1, the driving gear 204 can prompt the follower rack 205 to drive the guardrail 212 above the external plate 209 to move to the top of the heating disk 203, so that the guardrail 212 can effectively protect the overlapping state of the heating disk 203 and the kettle structure 1, and then cooperate with the driving gear 204 to prompt the follower rack 205 to drive the heat dissipation cover 211 above the external plate 209 to shield the heating disk 203 after use and quickly dissipate heat, so that the device can be effectively protected during and after use, thereby improving the stability of the kettle.

[0027] Specifically, a cross bar 207 is fixedly installed on the inner wall of the placement base 201, and the cross bar 207 is slidably connected to the inner wall of the follower rack 205. A pulley 206 is provided at the bottom end of the follower rack 205, and a slide groove 208 is opened on the inner wall of the placement base 201, and the pulley 206 overlaps the slide groove 208.

[0028] In this embodiment, the follower rack 205 can slide along the surface of the cross bar 207, and the pulley 206 can slide along the inner wall of the sliding groove 208, thereby improving the movement stability of the follower rack 205.

[0029] Specifically, an extension opening is opened inside the placement platform 202, and the bending rod 210 is located inside the extension opening.

[0030] In this embodiment, the bending rod 210 can slide along the interior of the extension opening, so that the movement of the bending rod 210 is restricted.

[0031] When in use, first place the protective heating structure 2 on the table, then connect the protective heating structure 2 to a power source so that the protective heating structure 2 is powered on;

[0032] Then, the built-in motor drives the driving gear 204 to rotate, and the rotation of the driving gear 204 drives the follower rack 205 to engage and transmit, and the movement directions of the two follower racks 205 are opposite, so the follower rack 205 drives the heat dissipation cover 211 and the guardrail 212 to slide in opposite directions inside the extension opening through the external plate 209 and the bending rod 210, so that the guardrail 212 gradually comes to the top of the heating plate 203, and the heat dissipation cover 211 moves to the farthest end of the heating plate 203;

[0033] Then, the kettle body 101 and the heating plate 203 are connected so that the guardrail 212 forms a wrapping protective structure for the connection between the kettle body 101 and the heating plate 203, thereby preventing the kettle body 101 and the heating plate 203 from separating due to collision.

[0034] After the heating plate 203 completes heating of the kettle body 101, the gear rod of the kettle body 101 is removed from the heating plate 203, and then the built-in motor is started in reverse. The built-in motor is started in reverse, prompting the built-in motor to drive the follower rack 205 through the driving gear 204 to drive the heat dissipation cover 211 and the guardrail 212 to move in the opposite direction, prompting the heat dissipation cover 211 to gradually come above the heating plate 203, and at this time the guardrail 212 moves to the farthest end of the heating plate 203, and then the fan inside the heat dissipation cover 211 is started, so that the fan begins to dissipate heat for the heating plate 203, so that the residual temperature of the heating plate 203 is quickly cooled down.

[0035] To sum up, the self-heating kettle is provided with a protective heating structure 2. Before the heating disk 203 heats the kettle structure 1, the driving gear 204 can prompt the follower rack 205 to drive the guardrail 212 above the external plate 209 to move to the top of the heating disk 203, so that the guardrail 212 can effectively protect the overlapping state of the heating disk 203 and the kettle structure 1. The driving gear 204 then prompts the follower rack 205 to drive the heat dissipation cover 211 above the external plate 209 to shield the heating disk 203 after use and quickly dissipate heat, so that the device can be effectively protected during and after use, thereby improving the stability of the kettle.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
