The working principle is as follows: when the honeycomb briquette 26 in the briquette pushing cavity 16 is burnt for a certain time and the heating effect is obviously weakened and needs to be replaced, the electric push rod 21 is started to drive the fixed block 19 to move upwards, the coal stove 15 is driven to move upwards through the upward movement of the fixed block 19, the pull rope 18 is driven to be stretched through the upward movement of the coal stove 15, the pull rope block 34 is pulled to move leftwards through the guiding of the guide block 33 to overcome the pulling force of the pull spring 35, the arc-shaped push block 36 is driven to move leftwards through the leftward movement of the pull rope block 34, so that the honeycomb briquette 26 in the briquette pushing cavity 16 is pushed to move leftwards through the arc-shaped push block 36, the arc-shaped push block 36 always supports the honeycomb briquette above without falling down, when the electric push rod 21 pushes the coal stove 15 to move to the upper limit position in the replacing cavity 12, the hinge plate 52 loses the support of the sliding cavity 53 at the moment, and naturally turns downwards through the, thereby driving the hinged plate 52 and the honeycomb briquette 26 on the upper side of the guide sliding cavity 37 to naturally slide down into the cleaning port 13 due to the gravity center being deviated to one side of the cleaning port 13, thereby facilitating the user to take the waste honeycomb briquette 26 out of the cleaning port 13, driving the connecting rod 23 to move up through the upward movement of the push plate 20, at this time, the clamping blocks 51 on the left and right sides extend into the clamping cavities 48 on the left and right sides on the top side for clamping, when the push plate 20 moves to the upper limit position in the communication cavity 22, driving the support plate 45 to move up to the upper limit position in the placing cavity 24 through the connection of the clamping blocks 51 and the clamping cavities 48, driving the pawl 43 to overturn downwards by overcoming the torsional spring force of the torsion spring 49 through the upward movement of the support plate 45, thereby moving out of the pawl cavity 25 on the bottom side, and driving the pawl 43 to extend into the third pawl cavity 25 from top to bottom through the upward movement of the support plate 45, the honeycomb briquette 26 in the placing cavity 24 is pushed to move into the pushing block cavity 29 by the upward movement of the supporting plate 45, at the moment, the motor 41 is started to drive the screw 40 to rotate, the threaded plate 38 is driven to move leftwards by the rotation of the screw 40 and the threaded connection between the threaded cavity 42 and the screw 40, so that the honeycomb briquette 26 at the top end in the placing cavity 24 is pushed leftwards to the replacing cavity 12 and pushed to the upper side of the honeycomb briquette 26 in the coal piling cavity 17, at the moment, the electric push rod 21 drives the pushing plate 20 to return downwards to the lower limit position, at the moment, the pull rope block 34 is pulled to return rightwards to the right limit position by the pulling force of the pull spring 35, at the moment, the honeycomb briquette 26 in the coal piling cavity 17 can move downwards to the coal pushing cavity 16, at the same time, the supporting plate 45 is driven to move downwards by the downward movement of the connecting rod 23, at the moment, the pawl 43 is limited by the limiting block 44, so that the pawl 43 is limited in the, at the moment, the clamping block 51 is disconnected with the clamping cavity 48, so that the honeycomb briquette 26 in the placing cavity 24 is completely added into the replacing cavity 12, the supporting plate 45 moves to the upper limit position of the placing cavity 24, the pawl 43 is limited by the side wall of the placing cavity 24, the pawl torsion spring 49 is in a tightening state, the supporting plate 45 can be driven to slide under the guide of the two side walls of the placing opening 28 to move to the upper limit position when the honeycomb briquette 26 in the placing cavity 24 is completely added into the replacing cavity 12, at the moment, because the supporting plate 45 is only supported by the clamping force of the clamping block 51 and the clamping cavity 48, an operator can quickly press the clamping block 54 downwards and overcome the clamping force of the clamping block 51 and the clamping cavity 48, so that the supporting plate 45 can be driven to move downwards and drive the clamping block 51 to be flush with the clamping cavity 48 at the bottom side, and meanwhile, the pawl 43 is just level with the pawl cavity 25 at the bottom side, because the pawl 43 is driven to slowly overturn into the pawl cavity 25 by the torsional spring force of the pawl torsional spring 49 due to the damping type hinge joint between the pawl 43 and the supporting plate 45, the user can put new honeycomb briquette 26 into the placing cavity 24 through the placing opening 28 for supplement.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
