EXAMPLE III

The heatable bowl of the first embodiment can only be used when plugged in. The heatable bowl of the second embodiment can only be used by supplying power to the storage battery, and once the storage battery is used up, it takes much time to charge the storage battery, and the heatable bowl cannot be used during charging for the service life of the storage battery. In order to solve the above problems in the first and second embodiments, the present embodiment combines the first and second embodiments to comprehensively design a heatable bowl that can be used by plugging in electricity, can be used by supplying power to a storage battery, and can charge the storage battery when plugged in electricity.

The electricity-plugging use function of the heatable bowl is realized by the following structure: referring to fig. 14, the portable heatable bowl of this embodiment is a container with a handle, and includes a bowl cover 3, a power supply base 7, a handle 8 and a bowl body 6 as a container body, wherein the handle 8 extends laterally from the bowl body 6. The bowl body 6 is placed on the power supply base 7, the power supply base 7 can supply power for the bowl body 6, and the connection relation of each electrical interface and each electric component in the power supply base 7 and the bowl body 6 is shown in figure 17. The power supply structure is the same as the structure of the power supply base 1 (see fig. 1) for supplying power to the bowl body 2 (see fig. 1) in the first embodiment, specifically: the power supply base 7 is provided with an electrical interface a, the electrical interface a includes a point taking interface a1 and a power supply interface a2, the structure of the power supply interface a2 is the same as that of the power supply contact of the power supply base 1 in the first embodiment, and the structure of the power taking interface a1 is the same as that of the commercial power interface 18 (refer to fig. 1) of the power supply base 1 in the first embodiment. The bottom of the bowl body 6 is provided with a power-taking interface Q2 of an electric component Q, the electric component Q is a heating element 23 (refer to fig. 2), the structure of the power-taking interface Q2 is the same as that of the power-taking contact of the bowl body 2 in the first embodiment, and the bowl body 6 is placed on the power supply base 7, so that the power-taking interface Q2 is connected with the power supply interface a 2. Therefore, the electric supply in the heatable bowl can directly supply power to the bowl body 6.

The structure that the heatable bowl is powered by the storage battery is as follows: referring to fig. 14, a battery (not shown) as an electric component P is provided in the handle 8, and the connection relationship among the electric interfaces and the electric components in the handle 8, the power supply base 7, and the bowl body 6 is shown in fig. 17. The accumulator is electrically connected to the power supply base 7, in particular: the side of the power supply base 7 extends upwards out of the side arm 71, and the top of the side arm 71 is provided with an electrical interface B. As shown in fig. 15, the end of the handle 8 connected to the bowl 6 is a connection seat 81, and the bottom surface of the connection seat 81 is provided with an electrical interface C of the storage battery. The electrical interface C is corresponding to the electrical interface B in position so that relative rotation of the power supply base 7 and the bowl 6 with the handle 8 around the vertical axis can make the two electrical interfaces B, C relatively close in the circumferential direction, i.e. as shown in fig. 16, the handle 8 leaves a space below the electrical interface C for the side arm 71 to extend into for connection, and as shown in fig. 14 after connection. The electric interface B is connected with the electric interface A through wires, namely the electric interface B is respectively connected with the electricity taking interface A1 and the power supply interface A2, so that after the electric interface B and the electric interface C are connected, the storage battery can supply power to the bowl body 6. Because the electrical interface C can be communicated with the electricity taking interface A1 through the electrical interface B, the power supply base 7 not only can directly supply power for the bowl body 6, but also can charge the storage battery when being connected with the commercial power. Because the commercial power supplies power for the bowl body 6 and the commercial power charges the storage battery into two separate lines, the use of the bowl body 6 is not influenced when the storage battery is charged. If the power supply base 7 is not connected with the mains supply, as long as the storage battery is electrified, the electrical interface B, C is connected, the storage battery can also supply power to the bowl body 6, and therefore the requirement of outdoor use can be met.

Referring to fig. 15, a circumferential self-locking structure 10 is disposed below the connecting seat 81, so that the two electrical interfaces B, C are automatically locked after being connected and cannot be separated by circumferential relative movement. The circumferential self-locking structure 10 comprises a self-locking block 87 and a connecting groove 82 which is fixed on the lower surface of the connecting seat 81 and is surrounded by three walls, wherein the side wall of the connecting groove 82 which is blocked on the relative rotation path of the side arm 71 and the handle 8 is a limiting wall 102, the wall of the other two walls which is slightly far away from the bowl body is a mounting wall 101, a return spring (invisible due to shielding) is arranged in the mounting wall 101, the rear end of the self-locking block 87 is connected with the return spring arranged in the mounting wall 101, the self-locking block 87 extends out from the mounting wall 101 along the radial direction of the bowl body 6 under the elastic force action of the return spring in a normal state, a guide inclined plane 870 (see figure 18) is arranged at the part of the self-locking block 87 extending out from the mounting wall 101, the self-locking block 87 is arranged on the path of the relative rotation of the side arm 71 and the handle, in the process that the power supply base 7 and the bowl body 6 provided with the handle 8 rotate relatively around a vertical axis to, the two electric interfaces B, C are pushed by the side arm 71 to move relatively close to each other in the circumferential direction until the two electric interfaces B, C are connected, and the self-locking block 87 automatically resets under the action of the return spring to realize self-locking after the two electric interfaces B, C are connected. The relative rotation of the power supply base 7 and the bowl 6 with the handle 8 about the vertical axis brings the two electrical interfaces B, C circumferentially closer together until they meet, i.e., they are stopped by the stopper wall 102 and cannot continue to rotate circumferentially in the original direction. If the handle 8 and the side arms 71 need to be separated, the handle 8 can be separated from the side arms 71 only by lifting the handle 8 upwards, which is very convenient. If need go out to use this heatable bowl, can be with power supply base 7, handle 8 and bowl body 6 split back, the branch carries again, and is more convenient. The circumferential self-locking structure 10 may instead be arranged at the top of the side arm 71, and correspondingly, an insertion block capable of being inserted into the connection groove 82 in the circumferential self-locking structure 10 is arranged below the connection seat 81, and the electrical interface C of the storage battery is arranged at the bottom of the insertion block.

Referring to fig. 14, the bowl 6 is detachably connected to the handle 8, and the mechanical connection structure between the bowl 6 and the handle 8 is the same as the mechanical connection structure between the bowl 2 (see fig. 6) and the handle 4 (see fig. 6) in the second embodiment, and will not be described again. The bowl 6 and the handle 8 are not directly electrically connected, but are electrically connected by means of a power supply base 7: in this embodiment, the insert 61 beside the bowl 6 is not provided with the anode contact 51 (see fig. 7) and the cathode contact 52 (see fig. 7), and the connecting seat 81 of the handle 8 is not provided with the power supply contacts 54 and 55 (see fig. 8), so that the battery in the handle 8 is not directly electrically connected with the side heating plate 2321 (see fig. 12) in the bowl 6.
