本申请的技术方案，具有如下优点：
1.本申请提供的限位装置，支撑住齿条的自由端，使齿条在滑移过程中保持在水平面内，从而增加支撑组件动作的平顺性。齿条夹设在齿轮和限位装置之间，进一步限定了齿条的滑移方向，并且防止齿条沿竖直方向与齿轮相脱开，使得齿条只能在唯一的运动路径上滑移，使支撑组件的运动更加平稳。回转支承件提供的回转支承，可以使齿条在滑移过程中与回转支承件发生滚动摩擦，减小齿条运动的阻力，使齿条的移动更加平顺。
2.本申请提供的限位装置，轴件为回转支承件提供了更可靠的支撑，并且轴件上设有第一限位台阶，以阻止回转支承件沿轴件滑移。限位架从另一侧夹紧回转支承件，以阻止回转支承件向轴件的另一端滑移。
3.本申请提供的限位装置，轴件上凸出形成第一限位台阶，回转支承件穿设安装在轴件上时，第一限位台阶阻止回转支承件继续沿轴件的轴向滑移。通过凸出轴件侧面的第一限位台阶，对回转支承件进行初步限位，阻止回转支承件穿设在轴件上时继续在轴件上滑动。在安装轴件时，需要先将回转支承件套设在轴件上，回转支承件穿设在轴件上的运动方向，指向轴件需要配合嵌入安装孔的一端，因此及时对回转支承件限位，防止回转支承件对轴件插入安装孔的影响。
4.本申请提供的限位装置，通过安装孔和卡槽对轴件的两端进行支撑，使轴件可以为回转支承件提供更可靠的支撑力，进一步提高了齿条移动的平顺性。
5.本申请提供的限位装置，轴件用于穿设回转支承件的一端卡嵌在卡槽内，且第二限位架与第一限位台阶之间形成恰好容纳回转支承件的限位间距。通过第一限位台阶与第二限位架从回转支承件两侧将回转支承件夹紧，进一步限位回转支承件，防止回转支承件在支撑齿条时沿轴件的轴向攒动，使回转支承件对齿条提供更稳定的回转支承。
6.本申请提供的限位装置，回转支承件还包括支撑轴承，支承轴承内圈与 轴件紧密贴合，支承轴承的外圈回转支撑在齿条下方，齿条发生平移时带动支承轴承的外圈相对于支承轴承的内圈转动。通过支承轴承来支撑齿条，支承轴承内圈与轴件相嵌合，嵌合通常为过盈配合或间隙配合。因此支承轴承的内圈与轴件的外侧圆周面紧密贴合，支承轴承的外圈支撑齿条，当齿条发生平移运动时，支承轴承的外圈与齿条之间发生滚动摩擦，支承轴承的外圈相对于内圈转动。使齿条的运动更加平顺。
7.本申请提供的限位装置，限位架上设有轴固定片，轴固定片两端分别连接轴件的端部和限位架，以阻止轴件相对于限位架转动。通过轴固定片将轴件与限位架连接锁止，使轴件无法转动，导致支承轴承内圈无法转动，支承轴承不易发生打滑，从而进一步提升了回转支承件的支撑效果，使齿条的移动更加平顺。
8.本申请提供的限位装置，通过异形定位孔来限制轴件的转动，通过第二限位台阶来定位轴固定片的嵌合位置，方便安装和拆卸。
9.本申请提供的燃气灶具，传动机构选用齿轮与齿条，由电机控制齿轮转动，由齿轮带动齿条滑移，从而推动支撑组件带动灶台上升或下降。齿轮与齿条配合传动的承载力大，因而齿条或齿轮不易发生损坏，且二者传动精准度更高，使得支撑组件的动作更加平稳，使灶台的上升、下降动作更加平顺。
10.本申请提供的燃气灶具，通过剪式升降机构带动灶台升降，由于剪式升降机构顶端的支撑点在动作过程中均保持在同一水平面内，因此受剪式升降机构支撑的灶台在上升、下降过程中保持水平状态。剪式升降机构受控于齿条，齿条具备上述剪式升降机构的优点，因此，齿条提供持续的、平稳的、方向水平的推力，使得剪式升降机构在带动灶台运动时更加平顺、稳定。
11.本申请提供的燃气灶具，通过连接杆连接上述剪式升降机构底部的两个活动端，齿条通过连接杆间接的控制上述两个活动端同时动作，以保持剪式 升降机构在动作过程中水平的支撑灶台。
12.本申请提供的燃气灶具，通过齿条挡块来连接齿条的自由端与连接杆。齿条挡块包括连接部和阻挡部，连接部用于套设在连接杆上，阻挡部连接齿条的自由端。阻挡部为齿条的自由端提供了一个安装平面，该平面限定齿条安装时的长度方向，再通过连接部的调整固定，使齿条固定在齿条挡块上的长度方向与其滑移方向一致。
13.本申请提供的燃气灶具，在活动端上设置限位轮，并且设置支撑限位轮的限位滑轨。限位轮为活动端提供支撑，减轻上述齿条运动过程中的负载，增加上述剪式升降机构动作的平顺性。且限位滑轨限定限位轮的滑移路径，进一步增加剪式升降机构动作的平顺性。
14.本申请提供的控制燃气灶具升降的方法，通过行程开关限制齿条的运动路线，在齿条运动路线的两端分别对应设置行程开关。当齿条运动到行程开关所在的位置时，触碰行程开关从而控制电机止停，使支撑组件恰好将灶台支撑在工作位或非工作位上。

实施例1
结合图1至图5，一种基于齿轮齿条机构的回转支承限位装置，包括：
回转支承件31，设于齿条23下方；
限位架，包括用以支撑电机21的第一限位架32，以及与第一限位架32相对设置的第二限位架33，回转支承件31的两端夹设在第一限位架32和第二限位架33之间。
对于回转支承件31的具体形式不做限制，本实施例中，回转支承件31选用轴承。作为可替换的实施方式，回转支承件31也可以是其他具有同样功能的部件或机构，以对齿条23形成回转支承。
对于回转支承件31的定位方式不做具体限制，本实施例中，回转支承件31通过轴件34穿设限位，且轴件34与限位架从回转支承件31两端阻碍回转支承件31沿轴件34的轴向滑移。
其中，轴件34上凸出形成第一限位台阶341，回转支承件31穿设安装在轴件34上时，第一限位台阶341阻止回转支承件31继续沿轴件34的轴向滑移。
对于轴件34的限位方式不做具体限制，本实施例中，第一限位架32和第 二限位架33上分别设有供轴件34嵌入的安装孔321和卡槽331。
其中，限位架上设有轴固定片35，轴固定片35两端分别连接轴件34的端部和限位架，以阻止轴件34相对于限位架转动。轴固定片35上设有供轴件34的端部穿过的异形定位孔351，轴件34上设有阻止轴固定片35继续通过的第二限位台阶342。
轴件34无法转动，导致回转支承件31的内圈无法转动，回转支承件31不易出现打滑，从而进一步提升了回转支承件31的支撑效果，使齿条23的移动更加平顺。
实施例2
如图6至图8所示，一种燃气灶具，包括：
支撑组件，一端用于支撑灶台4，另一端连接传动机构2；
传动机构2，包括电机21、受控于电机21的齿轮22、以及与齿轮22啮合的齿条23，齿条23一端连接支撑组件，通过齿条23将齿轮22的转动转换为支撑组件沿在工作位以及非工作位之间的升降运动；
实施例1的限位装置3，用以支撑齿条23的远离支撑组件的一端，齿条23夹设在齿轮22与限位装置3之间；
其中，传动机构2为受电机21控制的齿轮22与齿条23啮合而成，齿轮22转动带动齿条23滑移。齿条23的自由端连接支撑组件，齿条23滑移时带动支撑组件动作，支撑组件带动灶台4升起或下降。齿轮22与齿条23啮合的方式，可以更精确的传递动力，使齿条23的滑移更加平顺，进而带动支撑组件更加平顺的运动。限位装置3不但在齿条23移动过程中为齿条23的活动端提供可靠的支撑，还在齿条23运动方向的两侧限制齿条23晃动，使齿条23更加平稳的输出推动力。相比于用多个电动推杆推动灶台4进行升降运动来说，本 方案的限位装置3可以更加平稳的动作。支撑组件为一个整体，在运动过程中可以更好的保持整体的同步性，再加上齿条23输出的平稳的推力，使得灶台4的升降更加平顺。
在一个实施例中，传动机构2起传递动力的作用，将电机21输出的回转运动转化为齿条23的滑移运动。齿条23受控于齿轮22滑移，因此齿条23的自由端在滑移过程中靠近或远离整个传动机构2。支撑组件可以由连杆机构构成，连杆机构的输出端连接齿条23的自由端，齿条23的自由端向整个连杆机构传递动力，带动连杆机构整体动作，使位于连杆机构输出端的灶台4按照预设的轨迹运动。
其中，齿轮22位于齿条23上方，限位装置3位于齿条23下方，因此齿条23被支撑夹紧在齿轮22和限位装置3之间，防止齿条23沿竖直方向与齿轮22相脱开，使齿条23始终保持与齿轮22啮合。
如图6至图8所示，还包括支撑组件，支撑组件选用剪式升降机构1，剪式升降机构1顶端和底端对称设有4个支撑点，4个支撑点支撑在灶台4上可以使灶台4处于更平稳更可靠的支撑状态。同时，剪式升降机构1自身更平稳的支撑在相应的安装面上。剪式升降机构1底部一侧铰接在安装面上，另一侧为活动端，活动端与齿条23的自由端相连。齿条23的自由端推动活动端平移，从而带动剪式升降机构1顶部的四个支撑点同时上升或下降。
其中，剪式升降机构1底部的两个活动端通过连接杆11连接，连接杆11受控于齿条23，使剪式升降机构1底部的两个活动端受齿条23控制时可以同步运动，增加了剪式升降机构1整体动作的同步性，使灶台4的升降更平稳。
如图1和图8所示，连接杆11上安装有齿条挡块12，齿条挡块12与齿条23的自由端相连。齿条挡块12包括用以套设连接在连接杆11上的连接部，还包括用于安装连接齿条挡块12的阻挡部。阻挡部位于齿条23的侧面，且为齿 条23的连接提供了一个安装平面。该安装平面阻止齿条23向电机21的方向移动。同时，齿条23的自由端通过第二限位架33限位，第二限位架33阻止齿条23向远离电机21的方向移动。因此第二限位架33和阻挡部将齿条23夹设于二者之间，进一步限制齿条23的运动方向。
如图1、图6至图8所示，活动端上设置有限位轮13，限位轮13底部设有平行于运动路径的限位滑轨14。
如图2和图3所示，限位架包括平行设置的第一限位架32和第二限位架33，回转支承件31选用支撑轴承，且支撑轴承夹设于第一限位架32和第二限位架33之间。限位架上架设有用于穿设支撑轴承的轴件34。轴件34的端部通过轴固定片35与第二限位架33锁止固定，使轴件34无法相对于限位架转动。
如图6至图8所示，限位装置3和齿条挡块12分别设于齿条23运动路径的两端，齿条23位于限位装置3和齿条挡块12之间。在齿条23的自由端设有开关压片36，在齿条23推动剪式升降机构1的活动端时，剪式升降机构1带动灶台4上升。在上述过程中，开关压片36靠近限位架运动。限位架上对应开关压片36设有行程开关37。当开关压片36触碰行程开关37时，电机21止停，灶台4悬停在设定的最高处。
如图6、图7所示，齿条23在拉动剪式升降机构1的活动端时，剪式升降机构1带动灶台4下降，连接杆11上的齿条挡块12靠近限位架运动。齿条挡块12的阻挡部向限位架方向凸出，限位架上设有用于配合阻挡部的另一行程开关37。当阻挡部触碰另一行程开关37时，电机21止停。剪式升降机构1带动灶台4悬停在预设的最低位置。
实施例3：
结合图8、图9所示，
一种控制实施例2的燃气灶具升降的方法，包括如下步骤：
S1：判断燃气灶具是否开机；
S2：由控制器向传动机构2发送开机信号；
S3：当燃气灶具开机后，传动机构2中的电机21接收到开机信号而启动，电机21带动齿轮22顺时针转动；
S4：齿轮22带动齿条23平移，齿条23推动支撑组件带动灶台4发生上升动作；
S5：齿条23平移过程中靠近并触动行程开关37使电机21止停；
S6：支撑组件支撑灶台4保持在第一预定位置，第一预定位置即灶台4的工作位；
S7：判断燃气灶具是否关机；
S8：当燃气灶具关机后，控制器向传动机构2发送关机信号；
S9：传动机构2的电机21收到关机信号后，电机21启动并带动齿轮22逆时针转动；
S10：齿轮22带动齿条23反向平移,齿条23控制支撑组件带动灶台4发生下降动作；
S11：齿条23反向平移过程中靠近并触动另一行程开关37使电机21止停；
S12：支撑组件保持在第二预定位置，第二预定位置即灶台4的非工作位。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由 此所引伸出的显而易见的变化或变动仍处于本申请创造的保护范围之中。
