[0028] 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 in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] See attached document Figures 1 to 6A wireless heating cooker according to an embodiment of the present invention includes a cooker body 10 and a rechargeable battery 20. The cooker body 10 has a shell 11 and a pot body 12 disposed on the shell 11. The shell 11 has a mounting groove 111 for accommodating the rechargeable battery 20 on the lower side of the pot body 12. The mounting groove 111 has a communication port 1111 communicating with the outside. The rechargeable battery 20 is detachably (usually pluggable) mounted on the mounting groove 111 through the communication port 1111. In addition, the shell 11 is also equipped with a PCB board 13 and a heating element 14 for heating the pot body 12. The PCB board 13 is electrically connected to the heating element 14.

[0030] Thus, by detachably installing the rechargeable battery 20 onto the housing 11, users can purchase multiple rechargeable batteries 20 for backup. When the rechargeable battery 20 in use is low on power, it can be replaced with a spare rechargeable battery 20, thereby ensuring the heating effect of the wireless hot pot and preventing food from not reaching the appropriate temperature due to insufficient power, which would affect the consumption. The wireless hot pot of this application is very suitable for people and scenarios where it is inconvenient to obtain electricity, such as boarding students, campers, etc.

[0031] Furthermore, the communication port 1111 is located on the periphery of the housing 11, and the lower side of the mounting groove 111 has a clearance opening 1112, which connects to the outside. Thus, through the specific design of the mounting groove 111, the mounting groove 111 of this application can accommodate rechargeable batteries 20 of various capacities, resulting in better compatibility. Specifically, there is a common rechargeable battery 20 on the market, which is suitable for various wireless products, such as car wash water guns and car vacuum cleaners. This battery has multiple capacity options, and the only difference in size between different capacity rechargeable batteries 20 is the thickness (height). However, by setting the clearance 1112 of the mounting slot 111, this application allows even larger capacity batteries to be adapted to the shell 11 of the electric hot pot of this application. This allows consumers and merchants to configure larger batteries according to their specific needs, thereby reducing the number of battery replacements. Compared with existing electric hot pots (whose battery slots are usually of a fixed size and can only accommodate batteries of a fixed size), the electric hot pot of this application can accommodate rechargeable batteries 20 with different capacities, which is more versatile. Furthermore, due to the reasonable design of the shell 11 of this application (compact and small), the placement stability of the electric hot pot will not be affected when replacing rechargeable batteries 20 with different capacities.

[0032] It can be added that this universal rechargeable battery 20 also has a latch 21 and a sliding protrusion (usually strip-shaped). The latch 21 is linked to a linkage key 22, which allows the latch 21 to move downwards and disengage from the latching groove 1113 described below, so that the rechargeable battery 20 can be removed. Correspondingly, the mounting groove 111 is provided with a latching groove 1113 that matches the latch 21 of the rechargeable battery 20; the mounting groove 111 is provided with a sliding groove 1114 that matches the sliding protrusion of the rechargeable battery 20. This makes the replacement operation more convenient for users. In practical applications, the mounting groove 111 is provided with a metal insert for connecting with the metal spring of the rechargeable battery 20. The power supply to the rechargeable battery 20 is achieved through the connection between the spring and the insert.

[0033] Preferably, the housing 11 is provided with a step 15 corresponding to the communication port 1111. This step 15 design allows users to easily remove and install the rechargeable battery 20. Specifically, when removing or installing the rechargeable battery 20, according to most people's habits, their fingers are positioned at the step 15, allowing them to grip the center of the battery 20, making installation and removal easier. Of course, the PCB board 13 can also be electrically connected to a charging port 131 for charging the rechargeable battery 20. The charging port 131 is exposed on the outer surface of the housing 11, allowing the user to charge the battery 20 without disassembling it. The charging port 131 is typically located on the step 15, providing a semi-hidden effect for a more aesthetically pleasing appearance. Furthermore, the PCB board 13 can also be electrically connected to other function buttons to switch the working modes of the electric hot pot, such as: keep-warm function, noodle cooking function, rice cooking function, soup heating function, and food (vegetable) heating function, etc.

[0034] Typically, a sealing cover 16 can also be opened and closed on the upper side of the pot body 12. The sealing cover 16 is provided with a negative pressure hole and a negative pressure switch. This is existing technology and will not be described in detail here.

[0035] The housing 11 is typically made of plastic, and preferably, a heat-insulating structure is provided inside the housing 11. Generally, the housing 11 includes an upper shell 112 and a lower shell 113, which offers advantages such as easy demolding and manufacturing. Figure 6 As shown, the heat preservation structure can be heat insulation cotton 30 disposed between the shell 11 and the pot body 12, thereby improving the heat preservation and heating effect of the electric hot pot. The pot body 12 is usually made of food-grade stainless steel. The heating element 14 can be a ceramic heating element attached to the lower side of the pot body 12, and the ceramic heating element is electrically connected to the PCB board 13.

[0036] The key design feature of this invention is the detachable installation of the rechargeable battery into the casing. This allows users to purchase multiple rechargeable batteries for backup. When the battery in use runs low, it can be replaced with a spare, ensuring the heating effect of the wireless electric hot pot and preventing food from not reaching the appropriate temperature due to insufficient power, thus affecting consumption. It also offers advantages such as portability. Furthermore, the specific design of the mounting slot allows the electric hot pot to be compatible with rechargeable batteries of different capacities, meeting the battery matching needs of different businesses and users, further increasing the product's versatility and better meeting the actual needs of different customers. Additionally, it offers advantages such as easy assembly and disassembly, stable placement, and a heat-insulating structure that effectively improves the product's heat retention.

[0037] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
