For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0028] In one embodiment of the bread heating machine of the utility model, please refer to Figures 1 to 7The bread heating machine includes a base 100, a shell 200, a furnace body 300 and a lifting mechanism 400. The shell 200 is arranged on the base 100, and the furnace body 300 is arranged in the cavity of the shell 200. The lifting mechanism 400 includes a guide member 410, a lifting seat 420, a first elastic member 430, a damper 440 and a limit member 450. The guide member 410 is vertically arranged on one side of the furnace body 300, and the lifting seat 420 is slidably connected to the guide member 410 up and down. The lifting seat 420 is connected to an operating handle 460 extending out of the shell 200, and a support member 470 is provided on one side of the lifting seat 420, and the support member 470 extends into the furnace body 300. The first elastic member 430 is connected to the lifting seat 420 and is used to push the lifting seat 420 to reset upward; the damper 440 and the limit member 450 are respectively arranged on the lifting seat 420 and the base 100, and the damper 440 cooperates with the limit member 450, and the damper 440 forms a damping force for the lifting seat 420 to reset upward.

[0029] Specifically, after the bread is heated, the electromagnetic switch of the bread machine is powered off, and therefore, under the action of the first elastic member 430, the lifting seat 420 and the support member 470 will move upward together, and the bread placed in the oven body 300 can be ejected. During the upward movement of the lifting seat 420, the damper 440 cooperates with the limit member 450, and the damper 440 forms a damping force for the lifting seat 420 to reset upward, so that the lifting seat 420 rises smoothly; therefore, the rising speed and impact force of the lifting seat 420 can be reduced, which can effectively improve the convenience and safety of the bread heating machine, making the operation more convenient, and ensuring stability and reliability during use, which can play a good protective role for the lifting mechanism and avoid the problem of bread being ejected.

[0030] Furthermore, the damper 440 is disposed on the lifting seat 420, and the stopper 430 is disposed on the base 100, and the damper 440 and the stopper 430 are in sliding contact or rolling contact. Therefore, the damper 440 and the stopper 430 form a damping force of sliding friction or a damping force of rolling friction.

[0031] Further, refer to Figure 2 and Figure 4 The damper 440 is a rotary damper disposed on the lifting seat 420. The damper 440 is provided with a gear 441. The stopper 450 is provided with a rack 451, and the gear 441 is meshed with the rack 451. In this embodiment, when the lifting seat 420 moves upward to reset, the gear 441 is meshed with the rack 451, and the gear 441 rotates and drives the rotary damper 440 to rotate, thereby forming a damping force for the lifting seat 420 to move upward. Furthermore, the rotary damper is a one-way rotary damper. Therefore, when the lifting seat 420 is pressed down by the operating handle 460, the damping force of the damper 440 will not be received, which is convenient for operation.

[0032] Further, refer to Figure 3 and Figure 4 A connecting member 310 is extended from one side of the upper end of the furnace body 300. The first elastic member 430 is a tension spring. The upper end of the first elastic member 430 is connected to the connecting member 310, and the lower end is connected to the lifting seat 420. The tension spring provides an elastic force for the lifting seat 420 to return upward. In addition, the upper ends of the guide member 410 and the first member 450 are connected to the connecting member 310, and the lower ends are arranged on the base 100.

[0033] Further, refer to Figure 6 The lower end of the lifting seat 420 is provided with a second connecting member 421, and the second connecting member 421 is provided with a through hole 422. The lower end of the first elastic member 430 is provided with a limiting portion 431, the first elastic member 431 passes through the through hole 422, and the limiting portion 431 is limited to the bottom side of the second connecting member 421. The structure of the first elastic member 431 and the lifting seat 420 is simpler, and the installation is more convenient.

[0034] Further, refer to Figures 3 to 7 The lifting seat 420 includes a body 423 and a side plate 424. The body 423 is provided with a limiting cavity on the side closer to the furnace body 300. The limiting cavity is formed with a top wall 425 and a bottom wall 426. Both the bottom wall 426 and the top wall 425 are provided with a guide through hole 427. The side plate 424 is provided on the side of the body 423 closer to the furnace body 300. The upper end of the side plate 424 is provided with a connecting portion 428 extending into the limiting cavity, and the connecting portion 428 is limited to the bottom side of the top wall 425. The connecting portion 428 is provided with a second guide through hole 429. The guide member 410 is penetrated through the guide through hole 427 and the second guide through hole 429. Furthermore, a second elastic member 480 is also connected between the body 423 and the side plate 424. Specifically, the second elastic member 480 is a tension spring, and the second elastic member 480 pulls the connecting portion 428 to abut against the bottom side of the top wall 425. In this embodiment, the body 423 and the side plate 424 are connected by the second elastic member 480, so that the body 423 and the side plate 424 can be displaced and moved relative to each other, and the body 423 can drive the side plate 424 and the support member 470 disposed on the side plate 424 to reset upward through the second elastic member 480. However, when the support member 470 and the side plate 424 are stuck, and the electromagnetic switch in the bread heating machine is powered off and loses the limit on the body 423, the first elastic member 430 can push the body 423 to overcome the elastic force of the second elastic member 480 and move upward for a distance, so that the body 423 is separated from the limit member of the electromagnetic switch. After eliminating the stuck fault of the support member 470, it is easy to reset.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
