[0040] like Figure 1 - Figure 10 As shown, the pot lid 1000 provided by this utility model is provided with a first position detection element. The first position detection element cooperates with a second position detection element on the pot 2000 to detect whether the pot lid 1000 has rotated into place. One of the first and second position detection elements is a magnet 2110 capable of generating magnetic lines of force, and the other is a Hall effect detection mechanism. The Hall effect detection mechanism can sense the change in the magnetic field of the magnet 2110 during rotation to determine whether the pot lid 1000 has rotated into place. Figure 3 As shown. By sensing the change in the magnetic field lines of the magnet 2110 through the Hall effect detection mechanism, it is possible to detect whether the lid 1000 has rotated into place relative to the cookware 2000, thus solving the problem of detecting the fit between the lid 1000 and the cookware 2000 and improving safety and reliability.

[0041] The use of a Hall effect sensor in conjunction with a magnet 2110 to detect the relative position of two components is existing technology. This solution applies Hall effect detection to the lid 1000 and the cookware 2000, thereby automatically determining whether the lid 1000 has rotated into position. Subsequent cooking steps can only proceed when the lid 1000 has rotated into position.

[0042] In this embodiment, the pot lid 1000 includes a lid body and a handle base module 1100. The handle base module 1100 is installed on the top surface of the lid body and has a handle 2100 for the user to hold.

[0043] like Figure 2As shown, the first position detection component is a Hall effect detection mechanism, which includes a Hall element 1112. The Hall element 1112 is located at one end of the handle module 1100 near the handle 2100 of the cookware 2000. It enhances the sensing detection of the magnet 2110 at the end of the handle 2100 of the cookware 2000, so that when the handle module 1100 rotates to be parallel with the handle 2100 of the cookware 2000, the magnet 2110 on the end face of the handle 2100 of the cookware 2000 facing the opening of the cookware 2000 senses the Hall element 1112, and the lid 1000 rotates into place.

[0044] In other possible solutions, the Hall effect sensor can be placed on the cookware 2000, while the magnet 2110 can be placed on the lid 1000.

[0045] like Figure 4 and Figure 5 As shown, the Hall effect detection mechanism includes a Hall effect charging plate 1110, with a Hall effect element 1112 disposed on the Hall effect charging plate 1110; the handle base module 1100 includes a pot lid handle base 1120, which has a mounting slot 1121 for assembly and positioning, and the Hall effect charging plate 1110 is positioned and installed in the mounting slot 1121. Specifically, the pot lid handle base 1120 also has a positioning post 1122 protruding towards the Hall effect charging plate 1110, and the Hall effect charging plate 1110 has a positioning hole 1113 for the positioning post 1122 to pass through. First, align the Hall effect charging plate 1110 with the mounting slot 1121 and make the positioning post 1122 pass through the positioning hole 1113, and then use screws to tighten and fix the Hall effect charging plate 1110 onto the pot lid handle base 1120.

[0046] like Figure 6 - Figure 8 As shown, the handle base module 1100 also includes an end cap housing 1130, which is connected to the pot lid handle base 1120 and covers the Hall charging plate 1110. A first sleeve 1131 is provided on the side of the end cap housing 1130 facing the pot lid handle base 1120. The first sleeve 1131 is fitted onto the positioning post 1122 and abuts against the Hall charging plate 1110 to improve the stability of the Hall charging plate 1110.

[0047] The Hall effect charging board 1110 has a charging interface 1111, which is connected to the battery. The end cover housing 1130 has a through hole 1132 for mounting the charging interface 1111. The charging interface 1111 passes through the through hole 1132 and can be plugged into a charging connector on the outside of the end cover housing 1130. The charging interface 1111 can be a USB interface. For sealing and waterproofing, the end cover housing 1130 also has a sealing plug 1140 that closes the through hole 1132 from the outside. The outer surface of the sealing plug 1140 is flush with or lower than the outer surface of the end cover housing 1130.

[0048] At the root of the charging interface 1111 of the Hall charging board 1110, that is, at the root of the end away from the end cover housing 1130, a first sealing ring 1150 is provided on the periphery. An annular rib position 1133 is provided on the inner port of the through hole 1132 on the end cover housing 1130. The annular rib position 1133 is concentrically arranged with the through hole 1132. After the end cover housing 1130 is installed, the top of the annular rib is pressed against the first sealing ring 1150, thereby improving the sealing performance.

[0049] like Figure 9 As shown, a connecting rod 1141 is provided on the back of the sealing plug 1140, and the end cap housing 1130 is provided with a through hole 1134. An interference section 1142 is provided on the connecting rod 1141. The interference section 1142 passes through the through hole 1134 through elastic deformation, so that the interference section 1142 and the sealing plug 1140 are located on the inner and outer sides of the through hole 1134, respectively. During installation, the connecting rod 1141 can be forcefully passed through the through hole 1134 from the outside to the inside. After the interference section 1142 is completely passed through, the installation is completed. During normal use, the interference section 1142 will not come out of the through hole 1134, and the sealing plug 1140 has a margin for inward and outward movement.

[0050] like Figure 10 As shown, a second sleeve 1123, coaxial with the through hole 1134, is provided on the lid handle base 1120. When the sealing plug 1140 is in the sealing state, the connecting rod 1141 is located in the second sleeve 1123. The back of the end cap shell 1130 is provided with an inner skirt extending into the second sleeve 1123 and concentric with the through hole 1134. The inner skirt is annular. A second sealing ring 1160 is fitted on the circumferential outer wall of the inner skirt. After assembly, the second sealing ring 1160 and the top surface of the second sleeve 1123 are press-fitted to form a waterproof structure.

[0051] The Hall charging board 1110 is equipped with a connection port, which connects to the battery and motherboard inside the smart handle 1120 via a connecting cable to provide power and control to the system.

[0052] The components on the Hall effect charging board 1110 are coated with sealant to prevent moisture and water damage.

[0053] The end cap housing 1130 is screwed to the handle base 1120 of the pot lid 1000. A waterproof decorative sticker with adhesive backing is pasted on the outer side of the screw of the end cap housing 1130 to improve the overall sealing and waterproof performance. A through hole 1132 is made in the decorative sticker to accommodate the charging port 1111.

[0054] The cooking device provided by this utility model includes the aforementioned pot lid 1000. Since the cooking device provided by this utility model uses the aforementioned pot lid 1000, it also possesses the advantages of the pot lid 1000.
