[0042] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0043] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0045] See Figures 1-10 This utility model provides a novel insulated bowl, including a base 2 and a bowl assembly 1 detachably placed on the base 2. The bowl assembly 1 includes a bowl body 11 and a bowl lid 13 covering the top of the bowl body 11. The bowl body 11 has a first groove with a top opening for placing food. The bowl lid 13 is detachably placed on the top of the bowl body 11 to seal or open the first groove. The top of the base 2 has a second groove that matches the shape of the bowl body 11 and allows the bowl body 11 to be placed or removed. In addition, it also includes an electromagnetic coil module 3 disposed inside the base 2. The electromagnetic coil module 3 includes a first electromagnetic coil 31 disposed inside the base 2 and located below the second groove, a second electromagnetic coil 32 surrounding the outer part of the second groove, and a circuit board 33 electrically connected to the first electromagnetic coil 31 and the second electromagnetic coil 32 respectively. The bowl body 11 is made of stainless steel.

[0046] Therefore, based on the above structure, when the bowl 11 is placed into the second groove and the circuit board 33 is powered, both the first electromagnetic coil 31 and the second electromagnetic coil 32 are energized and generate an electromagnetic field. This electromagnetic field can form a magnetic current at the bottom and side of the bowl 11 and raise its temperature, thereby uniformly heating the food in the first groove.

[0047] Therefore, by making the bowl body 11 out of stainless steel and installing an electromagnetic coil module 3 inside the base 2, the bowl body 11 can be heated by energizing the electromagnetic coil module 3. This allows the bowl body 11 to be separated from the base 2, making it easier to remove and clean the bowl body 11. In addition, the electromagnetic coil module 3 includes not only a first electromagnetic coil 31 located below the second groove, but also a second electromagnetic coil 32 surrounding the outer part of the second groove, which can heat the bottom and sides of the bowl body 11, thus achieving comprehensive heating, more uniform heating, and high heating efficiency.

[0048] In this embodiment, the bowl lid 13 is also provided with a viewing window 131 and a vent 132. The viewing window 131 allows the user to easily observe the state of the food inside the bowl 11, and the vent 132 can expel the heat and water vapor generated by the food to prevent the internal pressure of the bowl 11 from being too high, thereby preventing the bowl from deforming or exploding.

[0049] See Figures 3-4 as well as Figure 6 The novel insulated bowl also includes a first magnetic block 14 disposed on the bowl body 11 and a second magnetic block 21 disposed in the base 2. When the bowl body 11 is placed into the second groove, the first magnetic block 14 and the second magnetic block 21 are magnetically attracted to fix the bowl body 11 in the second groove. Specifically, it also includes a fixing ring 12. The top of the bowl body 11 is bent outward to form a flange 111. The fixing ring 12 is fitted onto the bowl body 11 from bottom to top and hooked onto the flange 111 to achieve fixation. There are multiple first magnetic blocks 14, and the fixing ring 12 is provided with several mounting grooves 121 for placing the first magnetic blocks 14. Similarly, multiple second magnetic blocks 21 are also provided and are arranged in a ring inside the base 2. When the bowl 11 is placed into the second groove, several first magnetic blocks 14 and several second magnetic blocks 21 correspond one-to-one and are magnetically attracted to each other to achieve fixation, thereby preventing the bowl 11 from falling off the base 2 and ensuring the stability of the bowl 11 placed on the base 2.

[0050] See Figure 2 as well as Figures 8-9 The novel insulated bowl also includes an NTC temperature probe 4 inserted through the bottom of the second groove. When the bowl 11 is placed into the second groove, the NTC temperature probe 4 contacts the bottom of the bowl 11 to detect the temperature. Preferably, the NTC temperature probe 4 is a ceramic NTC temperature probe, which is not affected by electromagnetic fields, thus ensuring the accuracy of temperature detection.

[0051] The base 2 is also provided with a mounting bracket 6, which includes an upper bracket 61 and a lower bracket 62 arranged vertically. The lower bracket 62 is fixedly installed, and the upper bracket 61 is elastically abutted against the lower bracket 62 by an elastic member 7 and can move up and down. The top part of the upper bracket 61 extends into the second groove and the NTC temperature probe 4 passes through the top of the upper bracket 61.

[0052] Therefore, when the bowl 11 is placed into the second groove, the bottom of the bowl 11 can abut against the NTC temperature probe 4, and under the magnetic attraction of the first magnetic block 14 and the second magnetic block 21, the NTC temperature probe 4 and the upper bracket 61 can move downward and compress the elastic member 7; when the bowl 11 is taken out from the second groove, the elastic member 7 releases its elastic force and drives the upper bracket 61 to reset, thereby driving the NTC temperature probe 4 to reset.

[0053] Therefore, through the magnetic attraction between the first magnetic block 14 and the second magnetic block 21, the bowl 11 can be driven to abut against and compress the NTC temperature probe 4 to ensure the reliability of the contact between the two, thereby ensuring the accuracy of temperature detection.

[0054] Specifically, the upper support 61 includes a first plate 611 and a second plate 612 arranged vertically. The first plate 611 includes a protruding post 6111 located in the middle and whose top portion extends into the second groove, and a protruding ring 6112 surrounding the protruding post 6111 and clamped and fixed between the bottom of the second groove and the lower support 62. The NTC temperature probe 4 passes through the protruding post 6111. The first plate 611 is made of an elastic material. The second plate 612 is pressed against the bottom of the first plate 611 by a plurality of elastic members 7. Preferably, the elastic member 7 is a spring, one end of which abuts against the second plate 612 and the other end of which abuts against the lower support 62.

[0055] Therefore, when the bowl 11 is placed into the second groove, the bottom of the bowl 11 can abut against the NTC temperature probe 4 and cause the protrusion 6111 to undergo elastic deformation, thereby causing the second plate 612 to compress the spring and move downward; when the bowl 11 is taken out of the second groove, the spring releases its elastic force and causes the second plate 612 and the protrusion 6111 to reset and move upward, thereby causing the NTC temperature probe 4 to reset.

[0056] See also Figure 9 The lower support 62 also has a groove 621 formed on it to accommodate and avoid the second plate 612. A guide structure is provided between the second plate 612 and the groove 621. The guide structure includes a first guide groove 6121 and a first guide block 6122 disposed on the second plate 612, and a second guide groove 622 and a second guide block 623 disposed in the groove 621. The first guide groove 6121 and the second guide block 623 are slidably engaged, and the second guide groove 622 and the first guide block 6122 are slidably engaged. Thus, by providing a guide structure, the vertical movement of the second plate 612 can be guided and limited, thereby improving the sliding stability of the second plate 612.

[0057] See Figure 7 The novel insulated bowl also includes a power supply module 5 housed within the base 2. This power supply module 5 comprises a power board 51 and a battery 52. ​​The power board 51 has a power input interface 511, and the battery 52 is electrically connected to both the power board 51 and the circuit board 33. Thus, the battery 52 can supply power to the circuit board 33, thereby energizing the first electromagnetic coil 31 and the second electromagnetic coil 32. The power input interface 511 on the power board 51 can charge the battery 52.

[0058] In addition, in this embodiment, the power supply module 5 can be detachably plugged into the base 2. The power board 51 is also provided with a power output interface 512. When the power supply module 5 is pulled out from the base 2, the battery 52 can output power to external electrical devices through the power output interface 512, acting as a power bank with multiple functions.

[0059] In summary, the novel insulated bowl provided by this utility model has the following beneficial effects:
