Referring to Figures 1 and 2, the electric heating pot according to the embodiment of the utility model includes a pot body 1 and a pot cover 2, one end of the pot cover 2 is hinged to the corresponding end of the pot body 1 through a rotating shaft 4, and two hinge springs 5 are set on the rotating shaft 4, One end of the hinge spring 5 is connected to the pot body 1, and the other end is connected to the pot cover 2. This kind of electric heating pot is usually provided with a cover opening button and a buckle at the other end of the pot cover 2. The pot body 1 is snapped together, and after the user presses the lid opening button, the pot lid 2 bounces backward at a certain angle under the action of the hinge spring 5 to achieve the purpose of automatically opening the lid. In other embodiments, a separate mounting column can be provided at the corresponding part of the pot body, and the hinge spring can be set on the mounting column; the two hinge springs can also be integrated.

In the actual application process, due to the different performance of the hinge spring 5, the opening force of the pot cover 2 may be too large so that the entire electric heating pot bounces, or the opening force is too small, and the pot cover 2 cannot be fully opened, which affects the electric heating pot use effect.

Referring to Figures 1-4, the electric heating pot according to the embodiment of the present utility model further includes a damping shrapnel 6, and the damping shrapnel 6 is made of stainless steel and is in the shape of a strip. Install the damping shrapnel 6 on the pot lid 2. When the pot lid 2 is bounced by the hinge spring 5, the damping shrapnel 6 will squeeze and rub against the corresponding part of the pot body 1, and use the frictional damping force generated by the two to buffer the hinge spring. 5, thereby slowing down the speed at which the pot cover 2 bounces off, so that the pot cover 2 can be bounced off more smoothly. Specifically: the pot cover 2 of this embodiment includes a face cover 22 and a lining 21, and a hinged seat 3 is provided at the rear of the pot body 1, and the rotating shaft 4 is installed on the hinged seat 3, and the inner lining 21 is close to the hinged seat 3. One side is provided with a boss 211; the damping shrapnel 6 in this embodiment is roughly in an inverted L shape, and its transverse section is fixed to the boss 211 as the fixed part 61 of the damping shrapnel 6, and its vertical section is bent relative to the fixed part 61 The elastic arm 62 is formed so that the elastic arm 62 can extend between the side of the lining 21 and the hinge seat 3 .

This embodiment adopts the screw connection method to fix the damping shrapnel 6, specifically: this embodiment also includes locking screws 7, a through hole 611 is set on the fixed part 61 of the damping shrapnel 6, a threaded hole is set on the boss 211, and the locking screw 7 is locked into the threaded hole of the boss 211 through the through hole 611 to fix the damping elastic piece 6 to the upper surface of the boss 211. Preferably: in this embodiment, several positioning ribs 212 are also arranged on the peripheral side of the boss 211, and the upper ends of the positioning ribs 212 are higher than the upper surface of the boss 211. The holes are aligned to the threaded holes of the boss 211, which is convenient for screwing; after installation, the positioning rib 212 is offset against multiple parts of the damping shrapnel 6, which can prevent the damping shrapnel 6 from shifting and affect the use effect.

In other embodiments of the present utility model, the damping shrapnel can also be directly fixed to the inner liner by means of welding, injection molding connection and the like.

In the state shown in Figure 5, there is a gap between the elastic arm 62 and the inner surface of the hinged seat 3. At this time, the electric heating pan is in the closed state, and the damping shrapnel 6 will not generate frictional damping force; , the pot cover 2 bounces backward under the action of the hinge spring 5 . As shown in Figure 6, during the springing process of the pot cover 2, the elastic arm 62 of the damping shrapnel 6 touches the hinge seat 3, and as the opening angle of the pot cover 2 increases, the elastic arm 62 and the hinge seat 3 will squeeze each other , thereby generating a frictional damping force, which can slow down the elastic force of the hinge spring 5, reduce the speed at which the pot cover 2 bounces, and avoid some adverse effects caused by the quick bounce of the pot cover 2.

Generally speaking, after the damping shrapnel is fixed in a specific shape, the friction force generated by squeezing the corresponding part usually does not change, but due to the performance of the damping shrapnel itself, plus manufacturing and assembly errors, even if the same Different damping shrapnels have different damping effects, which makes the consistency of product performance poor. Referring to Figures 3 and 4, for this reason, the present embodiment installs an adjusting screw 8 on the elastic arm 62 of the damping shrapnel 6, and adjusts the frictional damping force of the damping shrapnel 6 through the adjusting screw 8, so that the springs of the hinge springs with different performances can be aimed at. The opening force is used to adjust the frictional damping force, so that the pot lid 2 can be opened more smoothly, and at the same time, the manufacturing accuracy requirements of the damping shrapnel 6 are reduced. In specific applications, a threaded hole 621 is provided on the upper part of the elastic arm 62, and the adjusting screw 8 passes through it. The threaded hole 621 is in contact with the side of the boss 211 of the lining 21 . Referring to Fig. 7, in actual application, if the elastic arm 62 cannot generate enough frictional damping force to stabilize the opening speed, the adjusting screw 8 can be rotated so that the elastic arm 62 moves toward the inner side of the hinge seat 3, which reduces the elasticity. The gap between the arm 62 and the inner surface of the hinge seat 3, in this way, when the pot cover 2 is bounced, the extrusion force generated by the elastic arm 62 will increase, and the contact area will increase accordingly, so it can provide greater Frictional damping force to balance the elastic force of the hinge spring. Conversely, if the elastic arm 62 produces too much frictional damping force and the pot lid 2 cannot be fully opened, the adjusting screw 8 can be reversely rotated so that the elastic arm 62 can move away from the inner surface of the hinge seat 3. In actual operation, the operator can repeatedly adjust until the pot lid 2 achieves a better and smooth opening effect; in addition, this embodiment adopts the adjustment screw 8 for adjustment, and the adjustment accuracy is higher. Referring to Figures 2 and 4, in order to facilitate adjustment by the operator, in this embodiment, a groove 31 is provided on the upper end surface of the hinge seat 3 corresponding to the position of the adjusting screw 8, and the screwdriver can pass through the groove 31 to rotate the adjusting screw 8. In other embodiments, if the position of the adjusting screw is lower, a through hole can be provided on the hinge base corresponding to the position of the adjusting screw.

Since the damping shrapnel 6 of this embodiment is fixed on the pot cover 2, the adjusting screw 8 is arranged on the elastic arm 62, that is to say: when adjusting the frictional damping force, the damping shrapnel 6 is still fixed on the pot cover 2, which is easy to operate , to avoid problems such as the need to remove the damping shrapnel 6 to adjust the frictional damping force, resulting in the loss of the damping shrapnel 6 .

As shown in Figures 4 and 5, in order to prevent the adjusting screw 8 from loosening, the above-mentioned threaded hole 621 can be designed as a flanging hole, which can be flanged to the pot cover 2 or to the hinge seat 3. After being set as a flanging hole, The thread fit length is extended to improve the connection strength of the adjusting screw 8 and ensure that the elastic arm 62 will not rebound after the position is adjusted.

As shown in Figures 3 and 5, in order to strengthen and stabilize the damping effect of the damping shrapnel 6, the elastic arm 62 of this embodiment is provided with an abutment portion 620 that protrudes toward the hinge seat 3. , relying on the abutment portion 620 and the hinge seat 3 to squeeze to generate frictional damping force. In practice, the elastic arm 62 can be partially bent to form an arc-shaped abutment portion 620, or a hemispherical abutment can be punched out through a stamping process. Section 620. The protruding abutting portion 620 is provided to stabilize the frictional damping force generated by the elastic arm 62, avoiding the reverse deformation of the part of the elastic arm 62 that contacts the hinge seat 3 due to extrusion, and the damping effect gradually improves after opening the cover many times. reduce.
