Specific embodiments

[0027] The following is a description of the preferred embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention and are not intended to limit the present invention.

[0028] As Figure 1 shown, a glass heating kettle with bottom temperature measurement includes an electromagnetic heating base 1 and a glass kettle 2 placed on the electromagnetic heating base 1. A measuring component 3 is provided at the bottom of the glass kettle 2, and the measuring component 3 is arranged inside the electromagnetic heating base 2. This position design not only makes the structure of the glass heating kettle compact but also can prevent the electromagnetic heating base 1 from being damaged due to collision.

[0029] Specifically, as Figures 2 to 5As shown in the figure, the electromagnetic heating base 1 includes a cover body 101. A cover plate 102 is arranged below the cover body 101. A first step position 1011 is arranged at the lower edge of the cover body 101, and a second step position 1021 is arranged at the upper edge of the cover plate 102. The first step position 1011 corresponds to the second step position 1021, so that there is no gap when the cover body 101 and the cover plate 102 are installed together, and the appearance is beautiful. A plurality of first connection holes 1012 are arranged below the cover body 101, and a plurality of second connection holes 1022 are arranged above the cover plate 102. The first connection holes 1012 correspond to the second connection holes 1022. By using screws to pass through the first connection holes 1012 and the second connection holes 1022, the cover body 101 and the cover plate 102 can be fixed together.

[0030] The measurement component 3 includes a support 301. An NTC temperature probe 302 is arranged on the support 301. A placement position 3011 is arranged on the support 301. A detection element 303 of a non-contact liquid sensor is arranged in the placement position 3011. In this embodiment, the detection element 303 is an annular aluminum sheet, and the placement position 3011 is also an annular groove, which is beneficial to the stable placement of the detection element 303. A silica gel sleeve 304 is also sleeved on the support 301. Figure 4 It can be seen that the silica gel sleeve 304 is tightly wrapped around the support 301 and has a waterproof effect on the support 301. The detection element 303 is connected to the control module, and the control module is connected to the electromagnetic heating disc 4; the detection element 303 is equivalent to a pad and forms an induction capacitor with the ground. When the surrounding environment remains unchanged, the capacitance value is fixed at a small value and has a fixed charge and discharge time. When water is added to the glass kettle 2, it is equivalent to a conductor approaching the liquid level detection element 303, and a distributed capacitance (coupling capacitance) will be formed between the water and the liquid level detection element 303. At this time, it is equivalent to a capacitor being connected in parallel to the detection port of the control module, increasing the capacitance of the liquid level detection element 303 as a whole. Therefore, it is detected whether there is water in the glass kettle 2, and according to the judgment result, the control module controls whether the electromagnetic heating disc 4 heats up. The non-contact liquid sensing technology is the prior art and is described in detail in the Chinese patent document (authorization announcement number CN203432646U, patent name: A non-contact liquid level detection device). The application principle of the detection element 303 of the non-contact liquid sensor in this application is the same as that of the above-mentioned document, so it belongs to the prior art and will not be elaborated here.

[0031] When the detection element 303 of the non-contact liquid sensor detects that there is no water inside the glass kettle 2, the non-contact liquid sensor transmits a signal to the control module, and the control module controls the electromagnetic heating plate 4 to stop heating the glass kettle 2, effectively avoiding dry burning of the glass kettle 2; the NTC temperature probe 302 is used to detect the water temperature inside the glass kettle 2, and the NTC temperature probe 302 is also connected to the control module. When the water temperature reaches the boiling point or the set temperature value, the NTC temperature probe 302 transmits a signal to the control module, and the control module controls the electromagnetic heating plate 4 to stop heating the glass kettle 2.

[0032] An electromagnetic heating plate 4 is arranged inside the electromagnetic heating base 1, the NTC temperature probe 302 is arranged in the middle of the electromagnetic heating plate 4, and an electromagnetic heating layer 205 for electromagnetic heating cooperation with the electromagnetic heating plate 4 is arranged at the bottom of the glass kettle 2. The electromagnetic heating plate 4 converts magnetic force into heat energy, and heats the water inside the glass kettle 2 through the electromagnetic heating layer 205. A reserved position is arranged in the middle of the electromagnetic heating layer 205. The meaning of the reserved position is that the bottom of the glass kettle 2 is screen-printed with the electromagnetic heating layer 205, and there is no electromagnetic heating layer 205 except for the reserved position. The reserved position is located at the center of the bottom of the glass kettle 2 and corresponds to the position of the NTC temperature probe 302; a through hole 1013 is arranged in the middle of the cover body 101, and the upper end of the NTC temperature probe 302 passes through the through hole 1013. When the glass kettle 2 is placed on the electromagnetic heating base 1, the upper end of the NTC temperature probe 302 abuts against the reserved position, which is convenient for the NTC temperature probe 302 to directly detect the water temperature inside the glass kettle 2 and avoid interference.

[0033] Limiting arc positions 1017 are arranged on both sides of the through hole 1013 to play a limiting role on the glass kettle 2, so that the glass kettle 2 is not easily displaced.

[0034] A first slot 1014 is arranged on one side of the cover body 101. The first slot 1014 is used to install a push plate. By pressing the push plate, the electromagnetic heating plate 4 can be controlled to open and close, playing the role of a switch. A plurality of first heat dissipation holes 1015 are arranged on the other side of the cover body 101, and a second slot 1016 is arranged below the first heat dissipation holes 1015. The second slot 1016 is convenient for wire installation and supplies power to the electromagnetic heating plate 4.

[0035] A blower 5 is arranged below the electromagnetic heating plate 4, the cover plate 102 is provided with a plurality of second heat dissipation holes 1023, and the blower 5 is arranged on the second heat dissipation holes 1023. Under the action of the blower 5, external gas enters from the first heat dissipation holes 101 to dissipate heat inside the electromagnetic heating base 1, and finally discharges from the second heat dissipation holes 1023.

[0036] A plurality of support pads 1024 are arranged below the cover plate 102. The support pads 1024 play a supporting role on the electromagnetic heating base 1, prevent water from entering the inside of the electromagnetic heating base 1, and effectively extend the service life of the electromagnetic heating base 1.

[0037] The glass kettle 2 includes a housing 201, a handle 202 is provided on one side of the housing 201, a water outlet 203 is provided on the other side of the housing 201, a kettle lid 204 is provided above the housing 201, and the handle 202 is designed to facilitate lifting the housing 201 so that the water in the housing 201 flows out from the water outlet 203.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
