Referring to fig. 1 to 7 of the drawings, a water boiling apparatus according to a preferred embodiment of the present utility model will be disclosed and described in the following description, wherein the water boiling apparatus includes a water bottle 100 having a glass liner (hereinafter, abbreviated as a water bottle 100) and a base 200, the water bottle 100 being detachably supported to the base 200, and the water boiling apparatus can be used for boiling water, i.e., for heating water, when the water bottle 100 is supported to the base 200, so that the temperature of water rises.

Specifically, the water kettle 100 includes a bottom case 10, a glass liner 20, a heating unit 30, an upper coupler 40, and an insulation unit 50.

More specifically, the bottom case 10 has a receiving space 11 and a top opening 12 communicating with the receiving space 11. In this particular example of the water heating device of the present utility model shown in fig. 1 to 7, the bottom case 10 is an injection-molded plastic part, the bottom case 10 includes a bottom wall 13 and a peripheral wall 14, the peripheral wall 14 integrally extends upward from the periphery of the bottom wall 13 to form the accommodation space 11 between the bottom wall 13 and the peripheral wall 14, and the peripheral wall 14 defines the top opening 12 such that the top opening 12 of the bottom case 10 communicates with the accommodation space 11. Preferably, the peripheral wall 14 of the bottom shell 10 is a cylindrical peripheral wall, and accordingly, the kettle 100 is a cylindrical kettle. Alternatively, in other examples of the water heating apparatus of the present utility model, the peripheral wall 14 of the bottom case 10 is a square column-shaped peripheral wall, and accordingly, the water kettle 100 is a square column-shaped water kettle.

With continued reference to fig. 4, the glass liner 20 has a heating space 21, the glass liner 20 is disposed on top of the bottom shell 10, and the bottom of the glass liner 20 closes the top opening 12 of the bottom shell 10. The heating unit 30 is provided at the bottom of the glass liner 20, and the heating unit 30 is accommodated in the accommodating space 11 of the bottom case 10. Preferably, in order to increase the utilization rate of the heat generated by the heating unit 30, the heating unit 30 has a bonding surface 31, and the bonding surface 31 of the heating unit 30 is directly bonded to the bottom surface of the glass liner 20.

It should be noted that in this specific example of the water heating apparatus of the present utility model shown in fig. 1 to 7, the glass liner 20 forms the heating space 21 separately, so that when water is contained in the heating space 21 of the glass liner 20, the glass liner 20 isolates the heating unit 30 from water contained in the heating space 21 of the glass liner 20, so that scale is prevented from being formed in the heating unit 30, and in this way, it is not only advantageous to enhance the user's use experience, but also to ensure water quality, avoiding contamination of water during heating.

The upper coupler 40 is disposed at the bottom of the bottom case 10, and the upper coupler 40 is connected to the heating unit 30, and the utility power can be supplied to the heating unit 30 through the upper coupler 40, so that the heating unit 30 generates heat to heat the water contained in the heating space 21 of the glass liner 20. In this specific example of the water heating apparatus of the present utility model shown in fig. 1 to 7, the bottom case 10 has a bottom through hole 15, the bottom through hole 15 is provided at the bottom wall 13 of the bottom case 10, and the bottom through hole 15 communicates with the receiving space 11, wherein the upper coupler 40 is integrally received in the receiving space 11 of the bottom case 10, and the bottom of the upper coupler 40 corresponds to the bottom through hole 15 of the bottom case 10, so that the upper coupler 40 is provided at the bottom of the bottom case 10.

With continued reference to fig. 4-6, the thermal insulation unit 50 includes an outer thermal insulation portion 51, the outer thermal insulation portion 51 being received in the receiving space 11 of the bottom shell 10, and the outer thermal insulation portion 51 including an outer lateral thermal insulation element 511 and an outer longitudinal thermal insulation element 512, the outer lateral thermal insulation element 511 being configured to isolate the heating unit 30 from the bottom wall 13 of the bottom shell 10, the outer longitudinal thermal insulation element 512 being configured to isolate the heating unit 30 from the peripheral wall 14 of the bottom shell 10. When the heating unit 30 generates heat to heat the water contained in the heating space 21 of the glass liner 20, the outer lateral heat insulating member 511 can reduce the heat conducted toward the bottom wall 13 of the bottom case 10, and the outer longitudinal heat insulating member 512 can reduce the heat conducted toward the peripheral wall 14 of the bottom case 10, so that the bottom case 10 can have a lower temperature to avoid the problem of scalding or deforming the bottom case 10 when the water heating device heats the water contained in the heating space 21 of the glass liner 20.

It should be noted that, unlike the conventional glass electric kettle described in the background art of the present utility model, in this specific example of the water heating device of the present utility model shown in fig. 1 to 7, the glass inner container 20 alone forms the heating space 21, the glass inner container 20 isolates the heating unit 30 from the water contained in the heating space 21 of the glass inner container 20, that is, the heat generated by the heating unit 30 is conducted to the water contained in the heating space 21 of the glass inner container 20 through the glass inner container 20, in order to avoid the problem that a large amount of heat generated during the water heating process occurs in the direction of the bottom shell 10 due to the relatively weak heat conducting capacity of the glass inner container 20, the kettle 100 isolates the bottom shell 10 from the heating unit 30 through the outer heat insulation part 51 of the heat insulation unit 50, specifically, the outer lateral heat insulation element 511 of the outer heat insulation part 51 isolates the heating unit 30 from the bottom shell 10, the outer side wall 13 of the bottom shell 10, the heat conduction to the bottom shell 10 through the heat insulation part 51 is prevented from being conducted to the bottom shell 10, and the heat conduction to the bottom shell 10 is prevented from being reduced in such a way that the heat conduction to the outer side wall 10 is prevented.

Referring to fig. 2 and 3, and referring to fig. 1, 4 and 6, the base 200 includes a chassis 210 and a lower coupler 220 disposed on the chassis 210, and the lower coupler 220 may be connected to a commercial power. When the water kettle 100 is supported on the base 200, the upper coupler 40 of the water kettle 100 and the lower coupler 220 of the base 200 are coupled to enable commercial power to be supplied to the heating unit 30 via the lower coupler 220 and the upper coupler 40, so that the heating unit 30 generates heat to heat the water contained in the heating space 21 of the glass liner 20.

It should be noted that the "the outer lateral heat insulating member 511 of the outer heat insulating portion 51 insulates the heating unit 30 from the bottom wall 13 of the bottom case 10" referred to by the present utility model does not particularly mean that the outer lateral heat insulating member 511 completely insulates the heating unit 30 from the bottom wall 13 of the bottom case 10, but allows the outer lateral heat insulating member 511 to have a small-sized perforation for passing a wire for conducting the upper coupler 40 and the heating unit 30.

With continued reference to fig. 4 to 6, in this particular example of the water heating apparatus of the present utility model, the outer longitudinal heat insulating member 512 of the outer heat insulating portion 51 integrally extends upward from the periphery of the outer lateral heat insulating member 511 so that the outer heat insulating portion 51 forms a unitary structure, wherein the outer heat insulating portion 51 is disposed in the receiving space 11 of the bottom case 10. That is, in this specific example of the water heating apparatus of the present utility model, the bottom case 10 and the outer heat insulating part 51 are assembled to the receiving space 11 of the bottom case 10 after being manufactured, respectively, so that the outer heat insulating part 51 is received in the receiving space 11 of the bottom case 10. Alternatively, in other examples of the water heating apparatus of the present utility model, the outer lateral heat insulating element 511 of the outer heat insulating portion 51 is formed at the bottom wall 13 of the bottom case 10, the outer longitudinal heat insulating element 512 is formed at the peripheral wall 14 of the bottom case 10, and the outer lateral heat insulating element 511 of the outer heat insulating portion 51 may be formed at the bottom wall 13 of the bottom case 10, and the outer longitudinal heat insulating element 512 may be formed at the peripheral wall 14 of the bottom case 10, for example, by a spraying process.

In order to further prevent the heat generated by the heating unit 30 from being conducted toward the bottom case 10, referring to fig. 4 to 6, a first gap 101 is provided between the outer lateral heat insulating member 511 of the outer heat insulating portion 51 and the bottom wall 13 of the bottom case 10, and a second gap 102 is provided between the outer longitudinal heat insulating member 512 and the peripheral wall 14 of the bottom case 10. It will be appreciated that air has a low coefficient of thermal conductivity, and by forming the first gap 101 between the outer lateral heat insulating element 511 of the outer heat insulating portion 51 and the bottom wall 13 of the bottom case 10, air may be allowed to exist between the outer lateral heat insulating element 511 of the outer heat insulating portion 51 and the bottom wall 13 of the bottom case 10 to further prevent heat generated by the heating unit 30 from being conducted toward the bottom wall 13 of the bottom case 10. Accordingly, by forming the second gap 102 between the outer longitudinal heat insulating element 512 of the outer heat insulating portion 51 and the peripheral wall 14 of the bottom case 10, air can be caused to exist between the outer longitudinal heat insulating element 512 of the outer heat insulating portion 51 and the peripheral wall 14 of the bottom case 10 to further prevent conduction of heat generated by the heating unit 30 toward the peripheral wall 14 of the bottom case 10.

Further, referring to fig. 4 and 6, the outer lateral heat insulating member 511 of the outer heat insulating portion 51 is fixedly installed to the bottom wall 13 of the bottom case 10 to ensure that the first gap 101 is reliably formed between the outer lateral heat insulating member 511 and the bottom wall 13 of the bottom case 10 for blocking heat generated by the heating unit 30 from being conducted toward the bottom wall 13 of the bottom case 10. Specifically, the outer lateral heat insulating member 511 has at least one first support column 5111 extending downward, the bottom wall 13 of the bottom case 10 has at least one second support column 131 extending upward, and the first support column 5111 of the outer lateral heat insulating member 511 and the second support column 131 of the bottom wall 13 of the bottom case 10 are mutually supported in a plugging manner to form the first gap 101 between the outer lateral heat insulating member 511 and the bottom wall 13 of the bottom case 10. Preferably, the first support column 5111 of the outer lateral heat insulating member 511 and the second support column 131 of the bottom wall 13 of the bottom case 10 are screw-coupled to fixedly mount the outer lateral heat insulating member 511 to the bottom wall 13 of the bottom case 10, thereby ensuring that the first gap 101 is reliably formed between the outer lateral heat insulating member 511 and the bottom wall 13 of the bottom case 10.

With continued reference to fig. 4 and 6, the outer surface of the top portion of the outer longitudinal insulating element 512 of the outer insulating portion 51 abuts against the inner surface of the peripheral wall 14 of the bottom case 10 to ensure that the second gap 102 is reliably formed between the outer longitudinal insulating element 512 and the peripheral wall 14 of the bottom case 10 for blocking conduction of heat generated by the heating unit 30 toward the peripheral wall 14 of the bottom case 10. It will be appreciated that since the outer longitudinal insulating element 512 and the outer transverse insulating element 511 are of unitary construction, and the outer transverse insulating element 511 is fixedly mounted to the bottom wall 13 of the bottom shell 10, the relative positions of the outer longitudinal insulating element 512 and the peripheral wall 14 of the bottom shell 10 can be maintained unchanged, ensuring that the second gap 102 is reliably formed between the outer longitudinal insulating element 512 and the peripheral wall 14 of the bottom shell 10. Specifically, the top portion of the outer longitudinal heat insulating member 512 extends outward and then downward such that the outer surface of the top portion of the outer longitudinal heat insulating member 512 protrudes from the outer surfaces of the middle and bottom portions of the outer longitudinal heat insulating member 512, so that the second gap 102 may be formed between the outer longitudinal heat insulating member 512 and the peripheral wall 14 of the bottom case 10 when the outer surface of the top portion of the outer longitudinal heat insulating member 512 abuts against the inner surface of the peripheral wall 14 of the bottom case 10.

Further, with continued reference to fig. 4 to 6, the bottom wall 13 of the bottom case 10 has at least one heat exchanging channel 132, and the heat exchanging channel 132 communicates the second gap 102 with the external environment, so that the heat generated by the heating unit 30 can be rapidly radiated to the external environment through the heat exchanging channel 132 of the bottom wall 13 of the bottom case 10 after being conducted to the second gap 102 through the outer longitudinal heat insulating member 512 of the outer heat insulating portion 51, to prevent the temperature of the bottom case 10 from being excessively fast raised. Further, with continued reference to fig. 4 to 6, the heat insulating unit 50 includes an inner heat insulating portion 52, the inner heat insulating portion 52 being accommodated in the accommodating space 11 of the bottom shell 10, wherein the inner heat insulating portion 52 includes an inner lateral heat insulating member 521 and an inner longitudinal heat insulating member 522 integrally extending upward from a periphery of the inner lateral heat insulating member 521, the inner lateral heat insulating member 521 being located between the heating unit 30 and the outer lateral heat insulating member 511, and the inner longitudinal heat insulating member 522 being located between the heating unit 30 and the outer longitudinal heat insulating member 512. That is, in the water heating apparatus of the present utility model, the outer heat insulating part 51 and the inner heat insulating part 52 of the heat insulating unit 50 form a double-layered heat insulating part to secure a heat insulating effect. Preferably, the inner insulation 52 is a metal or alloy piece that may be formed by, but not limited to, stamping.

It should be noted that the "the inner lateral heat insulating member 521 of the inner heat insulating portion 52 insulates the heating unit 30 from the outer lateral heat insulating member 511" referred to by the present utility model does not particularly mean that the inner lateral heat insulating member 521 completely insulates the heating unit 30 from the outer lateral heat insulating member 511, but allows the inner lateral heat insulating member 521 to have a small-sized penetration hole for passing a wire for conducting the upper coupler 40 and the heating unit 30.

In order to further prevent the heat generated by the heating unit 30 from being conducted in the direction of the bottom case 10, a third gap 103 is provided between the inner lateral heat insulating member 521 and the outer lateral heat insulating member 511, and a fourth gap 104 is provided between the inner longitudinal heat insulating member 522 and the outer longitudinal heat insulating member 512. It will be appreciated that by forming the third gap 103 between the inner lateral heat insulating element 521 of the inner heat insulating portion 52 and the outer lateral heat insulating element 511 of the outer heat insulating portion 51, air may be present between the inner lateral heat insulating element 521 and the outer lateral heat insulating element 511 to further prevent heat generated by the heating unit 30 from being conducted toward the bottom wall 13 of the bottom case 10. Accordingly, by forming the fourth gap 104 between the inner longitudinal heat insulating member 522 of the inner heat insulating portion 52 and the outer longitudinal heat insulating member 512 of the outer heat insulating portion 51, air can be made to exist between the inner longitudinal heat insulating member 522 and the outer longitudinal heat insulating member 512 to further prevent heat generated by the heating unit 30 from being conducted toward the peripheral wall 14 of the bottom case 10.

Further, the outer lateral heat insulating member 511 has at least one upwardly extending first mounting post 5112, the heating unit 30 has at least one downwardly extending second mounting post 32, opposite sides of the inner lateral heat insulating member 521 of the inner heat insulating portion 52 are fixedly mounted to the first mounting post 5112 of the outer lateral heat insulating member 511 and the second mounting post 32 of the heating unit 30, respectively, for example, a bottom side of the inner lateral heat insulating member 521 is screwed to the first mounting post 5112 of the outer lateral heat insulating member 511 by a screw, and a top side of the inner lateral heat insulating member 521 is screwed to the second mounting post 32 of the heating unit 30 by a screw. With such a structure as described above, on the one hand, the heating unit 30, the inner side heat insulating portion 52, the outer side heat insulating portion 51, and the bottom case 10 can be assembled as a single body, and on the other hand, the third gap 103 is reliably formed between the inner side lateral heat insulating element 521 and the outer side lateral heat insulating element 511, and the fourth gap 104 is reliably formed between the inner side longitudinal heat insulating element 522 and the outer side longitudinal heat insulating element 512. Preferably, the lateral heat insulating member 511 of the lateral heat insulating part 51 has at least one downwardly extending third mounting post 5113, and the upper coupler 40 may be screwed to the third mounting post 5113 of the lateral heat insulating member 511 by a screw.
