Since the dining stove is equipped with a hydraulic damper on the water tray, the buffering action of the flip cover is realized when the cover is opened or closed, and the collision noise of the flip cover and the water tray is reduced, and the flip cover is prevented from being damaged by the collision.

[24] Referring to FIG. 5 to FIG. 7 , the hydraulic buffer cylinder 4 includes a casing 41. The left and right ends of the casing 41 are respectively provided with a cover 42. The inner cover of the casing 41 is provided with two covers 42 Push axis 43 moving left and right, the push The shaft 43 is fixed with a piston 44 in the inner cavity of the outer casing 41. The piston 44 divides the inner cavity of the outer casing 41 into a first-stage cavity 4 11 and a secondary cavity 412. The piston 44 is disposed through the left and right end faces thereof and communicates with the first-stage cavity 411. And a through hole 441 of the secondary cavity 412, wherein the primary cavity 411 is provided with a return spring 46 connecting the piston 44 and one of the covers. A portion of the push shaft 43 located in the first chamber 411 is provided with a slot 431. The slot 431 is provided with a locking piece 45. One end surface of the piston 44 is in contact with the locking piece 45, and the other end surface is connected to the return spring 46. The inner chamber of the hydraulic buffer cylinder is filled with a liquid, such as hydraulic oil, required by the hydraulic device. The periphery of the piston 44 is provided with a sealing jaw 6 , and the outer side of the piston 44 is provided with a groove 442 , and the sealing jaw 6 is located in the groove 442 and forms a cavity 443 with the hole 441 . The connecting side of the cover 42 is provided with an annular groove 421, and the annular groove 421 is provided with a sealant ring 7.

 [25] The push shaft 43 has a counterbore 432 at one end of the secondary cavity 412, and the side of the push shaft 43 is located in the first cavity.

The portions of the 411 and the secondary chambers 412 are respectively provided with first and second pressure relief holes 433, 434, and the first pressure relief holes 433 pass through the conduit 435 to the bottom of the counterbore 432, the second pressure relief hole 434 and The counterbore 432 is in communication, and the opening of the counterbore 432 is provided with a positioning plug 47. The positioning plug 47 is fixed at the bottom of the counterbore 432 by a spring 48 with a steel ball 49 that blocks the outlet of the pipe 435. In the present embodiment, the positioning plug 47 is a screw.

 Referring to Figures 3, 4 and 8, the transmission mechanism 5 includes a drive shaft 51 that is fixedly coupled to the rotary base 32.

The drive shaft 51 has a turntable 52. The turntable 52 is provided with a ball hole 521. The ball hole 521 is provided with a ball 53. The working side of the turntable 52 is fitted with a deep and shallow wheel 54, and the deep and shallow wheel 54 is uniformly changed in depth. The shallow groove 541 is matched with the ball 53.
