Based on the examples in the implementation manners, other examples obtained by those skilled in the art without making creative efforts all belong to the protection scope of the present utility model.

Referring to Figures 1-4, the electric heating pot proposed by the preferred embodiment of the present invention includes a pot body 1 and a pot cover 2, and the pot cover 2 is hingedly connected to the pot body 1 through a rotating shaft 3, specifically, behind the pot body 1 There are two support plates (not shown in the figure) opposite to each other, each support plate is provided with a rotating shaft support hole, and there are two opposite installation plates 21 at the rear of the pot cover 2, each of which is installed The plate 21 is provided with a rotating shaft assembly hole 211. After the pot cover 2 is connected to the pot body 1, the end of the rotating shaft 3 is inserted into the rotating shaft support hole and the rotating shaft assembly hole 211. The support plate is usually located on the inner side of the mounting plate 21, and the rotating shaft assembly hole The shape and size of 211 match the shape and size of the rotating shaft 3, and the shape and size of the rotating shaft support hole are suitable for the rotation of the rotating shaft 3, so that the rotating shaft 3 can be driven to rotate in the supporting hole when the pot cover 2 is overturned. The pot body 1 and its related structures are known in the prior art, so this embodiment will not describe it in detail in conjunction with the accompanying drawings.

In order to automatically open the lid, the electric heating pot of this embodiment is also provided with a hinge spring 5 at the hinged joint between the pot lid 2 and the pot body 1. The hinge spring 5 includes a tubular main body 51 and two ends of the main body 51 spring arms 52, wherein one spring arm 52 is positioned on the pot body 1, the other spring ratio is positioned on the pot cover 2, and the main body 51 is sleeved on the rotating shaft 3. 2 pop open automatically for easy use. It can be understood that during the process of opening or closing the lid, the external force is transmitted to the main body through the spring arm. Since the pot body is fixed relative to the lid, the spring arm connected to the lid is under force. Larger, so that the main body twists on the shaft, that is, unilateral twisting phenomenon. This situation will not only generate noise, but more importantly, it will not be able to exert the optimal torque of the hinge spring, resulting in a decline in the opening and closing performance of the lid.

The solution proposed in this embodiment is to add a bushing 4 between the hinge spring 5 and the rotating shaft 3, and use the bushing 4 to make up the gap between the rotating shaft 3 and the hinge spring main body 51, thereby effectively supporting the hinge spring main body 51.

Specifically: the bushing 4 is fitted on the rotating shaft 3 , the main body 51 is fitted on the bushing 4 , and the bushing 4 needs to be installed through the main body 51 , and the wall thickness of the bushing 4 is defined as 0.3 mm to 5 mm. It can be understood that if the wall thickness of the bushing 4 is less than 0.3 mm, the bushing 4 is easily squeezed and deformed, and loses its supporting function. If the wall thickness of the bushing 4 is greater than 5 mm, not only the material cost is high, but also the bushing 4 and the hinge spring may be damaged. Assembling the main body 51 is difficult, the wall thickness of the bushing 4 is controlled within the range of 0.3 mm to 5 mm, taking into account cost and reliability, and ensuring that the bushing 4 can reliably fill the gap between the rotating shaft 3 and the hinge spring main body 51 .

It can be understood that if the width of the gap is less than 0.3mm, it is not convenient to assemble the hinge spring 5, and the hinge spring main body 51 and the bushing 4 are prone to relatively large friction. 51 support effect, the part of the hinge spring 5 sleeved on the shaft 3 will still produce unilateral distortion. The gap width is controlled within the range of 0.3mm to 3mm, and the function of the bushing 4 is improved without affecting the assembly. Reliably implemented. Preferably: the gap between the bush 4 and the main body 51 in this embodiment can be 0.3mm, 0.5mm, 0.8mm, 0.9mm, 1.5mm, 1.8mm, 2.0mm, 2.3mm, 2.8mm, 3.0mm, etc. .

For the convenience of assembly, the bushing 4 of this embodiment includes a sleeve 41 and a limiting step 42 arranged at one end of the sleeve 41. The limiting step 42 is formed by flanging the end of the sleeve 41, and the main body 51 is set on the On the sleeve 41, the axial length of the sleeve 41 must be greater than or equal to the length of the main body 51 to ensure that the sleeve 41 can penetrate the main body 51, and the setting of the limit step 42 can be used for the assembly of the hinge spring 5 and the bushing 4 Provide a reference, that is, when the limit step 42 is in contact with one end of the main body 51 during assembly, it indicates that the hinge spring 5 is installed in place, so as to facilitate installation; and during use, the limit step 42 can prevent the bushing 4 from shifting to one side , improve the installation stability of the bushing 4, and in actual application, the outer diameter of the limiting step 42 is larger than the outer diameter of the best main body part 51, so that the strength of the bushing 4 can be improved and the supporting effect is good. More preferably: the axial length of the sleeve 41 is greater than the length of the main body 51, the limit step 42 is close to the shaft support hole, and the distance between the limit step 42 and the shaft support hole is smaller than the other end of the sleeve 41 protruding from the main body 51 The length is designed in this way, in the case of a limited step 42, to prevent the excessive circumferential displacement of the bushing 4 and cause one end of the bushing 4 to retract into the main body part 51 of the hinge spring, further improving the installation stability of the bushing 4, specifically Remarks: If the bushing 4 is subjected to a force pointing to the centerline of the rotating shaft 3, because the limiting step 42 is against the main body 51, one end of the limiting step 42 of the bushing 4 will obviously not retract into the hinge spring main body 51; When the sleeve 4 is subjected to a force directed toward the end of the rotating shaft 3, the bushing 4 may gradually move toward the direction of the supporting hole of the rotating shaft. The distance is less than the length of the other end of the sleeve 41 protruding from the main body 51. At this time, the other end of the sleeve 41 is still outside the main body 51, so as to ensure that the sleeve 41 can always pass through the main body of the hinge spring 5 under any circumstances. 51, in order to provide effective support, thereby ensuring the optimization of torque.
