Example two:

referring to fig. 1 to 3 and 11 to 13, a lifting gas cooker includes a cooker body 100, the cooker body 100 includes a panel 110 and a bottom case 120, a burner 200, a gas supply system 300 and a lifting device 400 are disposed in the cooker body 100, and a stove frame 500 is further disposed on the panel 110.

The panel 110 has a burner through hole 111 and a hob through hole 112.

The lifting device 400 comprises a base plate 410, a bracket 420, a driving mechanism 430 and a furnace frame driving mechanism 440, wherein the base plate 410 is fixed on the back surface of the panel 110 through a plurality of mounting rods 411, the driving mechanism 430 comprises a sleeve 450 and a push rod 460, the sleeve 450 comprises an upper shell 451 and a lower shell 452, the upper shell 451 and the lower shell 452 are detachably connected, a through hole 4511 is arranged at the upper end of the upper shell 451, a base surface 4521 is arranged in the lower shell 452, a positioning hole 4522 is arranged on the base surface 4521, the upper shell 451 is sleeved in the lower shell 452, and the bottom surface of the upper shell 451 props against the base surface 4521. The inner surface of the upper housing 451 is provided with a slide groove 453 and a second helical tooth block 454, the second helical tooth block 454 is located below the slide groove, and the slide groove 453 and the second helical tooth block 454 are located on different circumferences.

The push rod 460 includes a lifting rod 461 and a top rod 462, a groove is provided at the bottom of the lifting rod 461, and the top of the top rod 462 is embedded in the groove of the lifting rod 461. A helical tooth block 463 is provided on the outer circumference of the lower portion of the elevating rod 461.

The push rod 460 is installed in the sleeve 450, the upper end of the lifting rod 461 passes through the through hole 4511 of the upper housing 451, the push rod 462 passes through the positioning hole 4522 of the lower housing 452, the push rod 462 is connected with the base 4521 of the lower housing 452 through the coil spring 470, the outer circumference of the push rod 462 is provided with the spring projection 4621, and the coil spring 470 is defined between the spring projection 4621 and the base. The skewed tooth block 463 may be slidably coupled to the slide groove 453 or abut against the second skewed tooth block 454.

The structure of the burner 200 of the present embodiment is the same as that of the burner 200 of the first embodiment, and the description thereof is omitted.

Referring to fig. 11 to 13, in operation, the bracket 420 is mounted on the upper end of the elevating rod 461, and the elevating rod 461 is pushed up by the elastic force of the coil spring 470, thereby pushing the burner 200 out of the panel 110. When the burner 200 needs to be lowered, the burner 200 is pressed downwards by force, the burner 200 drives the lifting rod 461 to slide downwards through the bracket 410, the skewed tooth block 463 slides in the sliding groove 453 at the moment, after the skewed tooth block 463 is separated from the sliding groove 453, the inclined surface of the skewed tooth block 463 is abutted against the inclined surface of the second skewed tooth block 454, the skewed tooth block 463 deflects under the guiding action of the two inclined surfaces, namely, the lifting rod 461 is driven to rotate anticlockwise while sliding up and down, when the spiral spring 470 is compressed to a certain degree, the burner 200 cannot be lowered any more, and at the moment, the burner is slightly lower than the panel 110. Then the external force disappears, the elastic force of the coil spring 470 pushes up the top rod 462 to drive the lifting rod 461 to move upwards, and since the slanting teeth 463 rotates a certain angle during the descending process, the slanting teeth 463 abuts against the second slanting teeth 454 during the ascending process, so that the lifting rod 461 cannot continue to move upwards. At this time, the surface of the burner 200 is just flush with the panel 110. When the burner 200 needs to be lifted, similarly, the burner 200 is pressed downwards by an external force, the burner 200 drives the lifting rod 461 to move downwards, in the process of moving downwards, the helical tooth block 463 rotates under the guiding effect of the inclined plane, after the helical tooth block 463 and the second helical tooth block 454 are not opposite, after the external force is released, the elastic force of the spiral spring 470 pushes the whole push rod 460 to move upwards until the lifting rod 461 rises to the original position, and at this time, the burner 200 can be used normally.

It can be seen that the lifting principle of the present drive mechanism 430 is similar to that of a ball point pen. The lifting or falling of the combustor 200 is realized by skillfully utilizing the matching of the two inclined tooth blocks and the sliding grooves, and two different stations of the combustor 200 are provided. And because the driving mechanism realizes the lifting of the burner by using a mechanical structure, no electric spark is generated in the lifting process, and the driving mechanism is safer compared with the push rod motor of the first embodiment. Of course, because the helical tooth blocks can rotate by a certain angle in the descending process at every time, the lifting device can be more smooth through the reasonable design of the angle and the reasonable number of the helical tooth blocks. Suitably, the number of the second skewed tooth blocks is matched with that of the skewed tooth blocks.

Further as a preferred embodiment, the top end of the push rod 460 includes a cylindrical connector. The support 420 on be equipped with the mounting hole, the connector embolia in the mounting hole, when push rod 460 took place to rotate at the in-process that descends, utilized the cooperation of connector and round hole for support 420 can not take place to follow the push rod rotation.

Further in a preferred embodiment, the helical tooth block 23 includes an arc-shaped inclined surface. The inclined plane of the arc is utilized, so that the inclined tooth block is smoother in rotation.

Further, in a preferred embodiment, there are a plurality of driving mechanisms 430, and the plurality of driving mechanisms 430 are uniformly distributed on the support 410. Since the push rod 460 provides a unidirectional force, the lifting of the support 420 can be more smoothly performed by using a plurality, e.g., 3, of the driving mechanisms 430.

In some embodiments, the lifting rod 461 and the sleeve 450 of the driving mechanism 430 may not adopt a structure of a helical gear block, for example, the helical gear block may be modified into two or more projections, the two projections are mirror images of each other, and the projections and the sliding grooves are not located at the same position, and the second helical gear block may be two plate-shaped positioning blocks, the positioning blocks may slide in the sliding grooves, and after the positioning blocks are separated from the sliding grooves, the positioning blocks are located below the projections by rotating the positioning blocks, so that the positioning blocks abut against the projections when the positioning blocks are lifted, and the push rod cannot be lifted further. Although this structure is simpler, since the rotation of the push rod is completely controlled by the hand, the rotation angle of the positioning block is difficult to control, and thus the elevation is difficult to control.

In some embodiments, the lifting rod 461 and the push rod 462 can be integrally formed, the integrally formed push rod 460 has better strength, and only a spring bump is required to be formed on the push rod 460 when in use, and then the slanting tooth 463 can be fixed on the push rod 460 by welding, bonding or screwing.

In some embodiments, as pushrod 460 descends, it may pass down through sleeve 450. That is, the sleeve 450 may not require a lower housing as in the previous embodiment, but may include only an upper housing.
