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

In addition, in the present invention, in the case where the description is not made to the contrary, the use of the directional words such as "upper, lower, left, and right" generally means the upper, lower, left, and right as shown with reference to the drawings; the term "inner and outer" refers to the inner and outer contours of the respective component parts themselves.

Referring to fig. 1, an electric stewpot according to an embodiment of the present invention includes a pottery pot 1, a heating device 3, a locking member 4, a base 5, and a pot body 6, wherein: the outer shell structure that forms electric stewpot is connected with base 5 to the a kind of deep pot body 6, and pottery pot 1 passes through locking piece 4 and base 5 fixed connection, and heating device 3 sets up to the annular and around pottery pot 1's lateral wall, and when heating device 3 circular telegram, directly heats pottery pot 1, can also cover on the pottery pot 1 and close pot cover 2.

Be provided with coupling groove 10 on the lateral wall of pottery pot 1, the upper end of locking piece 4 stretches into in this coupling groove 10, so that the upper end of locking piece 4 and the lateral wall fixed connection of pottery pot 1, the lower extreme of locking piece 4 is connected to on the base 5, thereby with pottery pot 1 and base 5 relatively fixed, thus, although the aluminium pot has been cancelled, but, cooperation through locking piece 4 and coupling groove 10, the fixing of pottery pot 1 with locking piece 4 has been realized simply and conveniently, rethread locking piece 4 and base 5's fixed connection, make pottery pot 1 be connected fixedly through locking piece 4 and base 5, moreover, the steam generator is simple in structure and is connected reliably.

Referring to fig. 2, 3 and 5, in one embodiment, the heating means 3 is disposed at a position higher than the position at which the coupling groove 10 is disposed, in the use orientation of the electric stewpot. The locking piece 4 comprises a connecting part 40, one end of the connecting part 40 extends into the connecting groove 10, the other end horizontally extends out of the connecting groove 10 along the diameter direction of the pottery pot 1, and the part of the connecting part 40 extending out of the connecting groove 10 can limit the heating device 3 from falling off the pottery pot 1 downwards, so that even if the heating device 3 slides downwards to be in contact with the locking piece 4, the part of the connecting part 40 horizontally extending out of the outer side wall of the pottery pot 1 can also horizontally and upwards support the heating device 3, so that the heating device 3 can continuously heat the pottery pot 1.

In the existing electric stewpot provided with the aluminum pot, in order to prevent the heating ring on the aluminum pot from falling off, the existing means is to make a rolling rib at the corresponding position of the outer wall of the aluminum pot, the processing technology of the rolling rib is complex, the radial dimension of the rolling rib is limited, and when the heating ring deforms greatly, the rolling rib is not enough to limit the heating ring from falling off downwards. The connecting portion 40 in this embodiment can be as long as possible within the allowable space range, and even can cover the gap between the pottery pot 1 and the cooker body 6, so that the portion of the connecting portion 40 extending out of the connecting groove 10 limits the falling of the heating device 3, the structure is more reliable, the manufacturing difficulty does not exist, and the electric safety of the electric stewpot is influenced by the fact that the heating device 3 falls onto the base 5 can be reliably avoided.

Referring to fig. 3, the connecting grooves 10 may be provided in two and located at the two ends of the pottery pot 1 in the same diameter direction, and the locking member 4 has two connecting portions 40, respectively, and both the connecting portions 40 partially protrude into the connecting grooves 10. The size of the slot of the connecting groove 10 may be slightly larger than the size of the end of the connecting portion 40 extending into the connecting groove 10, so that the connecting portion 40 can move slightly in the connecting groove 10 to adapt to manufacturing or installation errors.

A coupling portion 41 is coupled between the two coupling portions 40, and the coupling portion 41 serves to fix the two coupling portions 40 to the base 5 together, thereby simplifying the assembly process of the locking member 4 with the base 5. The coupling part 41 may include a vertical bar 410 coupled to each of the coupling parts 40, and a cross bar 411 coupled between the two vertical bars 410, wherein the vertical bar 410 extends downward from one end of the coupling part 40 protruding out of the coupling groove 10, and the cross bar 411 is disposed at a lower end of the vertical bar 410 and spaced apart from an outer bottom wall of the earthenware pot 1 up and down, so that heat of the earthenware pot 1 can be reduced from being transferred to the entire locking member 4 through the cross bar 411.

The connecting portion 40 and the combining portion 41 may be provided as an integrally molded member, for example, bent and formed using a bar-shaped metal structure. The locking member 4 further includes a tension portion 42, and in some embodiments, the upper end of the tension portion 42 is provided with a connection ring 421, and the connection ring 421 is sleeved on the cross bar 411. The lower end of the tightening part 42 is provided with a coupling screw 420, and as shown in fig. 1 and 4, when the locking member 4 is fixedly coupled to the base 5, the lower end of the tightening part 42 passes through the base 5, and the nut 8 and the washer 7 are threadedly coupled to the coupling screw 420 on the outer bottom surface of the base 5, thereby achieving the fixed coupling of the lower end of the locking member 4 to the base 5. Since a certain allowance is left between the connection part 40 and the connection recess 10, in order to smoothly connect the pottery pot 1 to the base 5 such that the bottom wall of the pottery pot 1 is substantially parallel to the base 5, the position of the connection ring 421 on the cross bar 411 can be finely adjusted.

The upper end of the pot body 6 can also be provided with a limiting notch 60, the earthenware pot 1 is provided with a limiting boss 11, and when the earthenware pot 1 is embedded in the pot body 6, the limiting boss 11 is embedded in the limiting notch 60, so that the earthenware pot 1 is limited from rotating circumferentially relative to the pot body 6.

The heating device 3 may be provided as a ring-sheet shaped heating ring with an opening, which abuts against the outer side wall of the pottery pot 1, so that the heat of the heating device 3 is efficiently conducted to the pottery pot 1. When assembling, the heating device 3 and the locking member 4 may be spaced up and down, and the locking member 4 is used to restrict the heating device 3 from slipping off when the heating device 3 is loosened.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
