另外,本申请提供的上述技术方案中的盖体还可以具有如下附加技术特征:
上述技术方案中,所述调压阀装置包括:调压阀,具有多个挡位,且多个挡位中的一者为所述初始挡位;联动件,适于锁定所述调压阀的挡位,其中,当所述盖体装置开盖,所述盖体装置联动所述开合盖联动机构,并通过所述开合盖联动机构联动所述联动件,使所述联动件解除对所述调压阀的挡位锁定;复位驱动件,与所述调压阀配合,且当所述联动件解除对所述调压阀的挡位锁定,所述复位驱动件驱动所述调压阀至所述初始挡位。
在该技术方案中,在使用调挡功能时,将调压阀调至相应挡位后,利用联动件对调压阀锁定挡位,可以使得调压阀的挡位维持稳定可靠,防止调压阀在非调节情形下跳挡,产品限压功能更精准可靠。
利用复位驱动件,当联动件解除对调压阀的挡位锁定,复位驱动件驱动调压阀复位至初始挡位,实现对调压阀的自动驱动复位。这样,利用开合盖联动机构联动联动件,使联动件解除对调压阀的挡位锁定,可以自动触发复位驱动件驱动调压阀复位的动作进行,可靠地实现了开盖时调压阀装置自动复位,无需用户对调压阀装置手动归挡,使用操作更加方便、简洁,同时避免了用户使用调挡功能时忘记对调压阀装置复位引起的水烧干等风险和危害,提升产品的安全性。且本结构中,驱动调压阀复位的动力 来自于复位驱动件,这样可以有效保障开合盖联动机构的精准性不受调压阀干扰,保证产品的开合盖功能稳定、可靠,有效保障产品安全。
上述任一技术方案中,所述开合盖联动机构包括自锁滑块,所述自锁滑块设置在所述盖体装置上,且所述盖体装置开盖联动所述自锁滑块运动,并通过所述自锁滑块联动所述调压阀装置的联动件,使所述联动件解除对所述调压阀装置的调压阀的挡位锁定。
在该技术方案中,利用自锁滑块对调压阀装置联动以触发调压阀装置自动复位,满足开盖触发调压阀装置自动复位的同时,具有结构简单,成本低的优点,简言之,可以利用盖体原本具有的自锁滑块来对调压阀装置进行开盖触发控制,改造成本低,且部件之间的相适性好,改造简单、方便。
上述任一技术方案中,所述自锁滑块上设有止挡部,所述联动件上限定有适配所述止挡部的止挡结构;当所述盖体装置开盖,所述止挡部作用于所述止挡结构并驱动所述联动件运动,使所述联动件解除对所述调压阀的挡位锁定。
在该技术方案中,自锁滑块上设置止挡部用于与联动件的止挡结构止抵配合,使得自锁滑块与联动件之间传动,这样,盖本体开盖以联动自锁滑块运动,并通过自锁滑块联动联动件使联动件解除对调压阀的挡位锁定,形成开盖时控制调压阀自动复位的功能,解决调压阀的使用方便性问题,且止挡部的限定具有结构简单,易于实施的优点,可以方便、简单地对现有自锁滑块改造获得,改造成本低,适于在领域内推广。
上述任一技术方案中,所述止挡部为设置在所述自锁滑块上的凸板或卡钩,所述止挡结构为止挡凸块,所述止挡凸块的至少一部分朝所述自锁滑块延伸,当所述盖体装置开盖,所述凸板或卡钩拉动所述止挡凸块,使所述联动件朝远离所述调压阀的方向运动。
在该技术方案中,设置止挡部为凸板或卡钩,使自锁滑块运动时利用其止挡凸块拉动止挡凸块以驱动联动件远离调压阀,可以更平稳地实现驱动联动件对调压阀解锁,同时,具有结构简单,加工方便,成本低的优点。
上述任一技术方案中,所述盖体装置上设有轨道槽,所述联动件的一 部分位于所述轨道槽内,且所述轨道槽适于对所述联动件的运动导向。
在该技术方案中,设置轨道槽对联动件的运动导向,这样,可以使得联动件的运动更加精准,且使得联动件与调压阀的配合更加精准,更进一步强化了联动件对调压阀的限位可靠性,从而提升对调压阀的挡位锁定的可靠性。
上述任一技术方案中,所述盖体装置上还设有复位引导槽,所述复位引导槽位于所述轨道槽与所述调压阀之间,所述联动件的一端自所述复位引导槽穿过与所述调压阀配合以对所述调压阀锁定,其中,所述复位引导槽与所述轨道槽之间间隔地分布。
在该技术方案中,设置复位引导槽,使复位引导槽与轨道槽之间间隔地分布,且联动件的一端自复位引导槽穿过与调压阀配合以对调压阀锁定,这样,可以进一步提升对联动件的导向效果,且可以防止联动件以第二限位结构为支点发生偏转,进一步提升联动件的装配可靠性和稳定性。
上述任一技术方案中,所述调压阀装置包括:调压阀,具有多个挡位,且多个挡位中的一者为所述初始挡位;复位驱动件,与所述调压阀配合;其中,所述开合盖联动机构包括联动件,所述联动件适于锁定所述调压阀的挡位,所述联动件设有自锁销,所述自锁销配置为与锅牙配合使开盖时通过所述锅牙联动所述联动件运动,使所述联动件解除对所述调压阀的挡位锁定;当所述联动件解除对所述调压阀的挡位锁定,所述复位驱动件驱动所述调压阀至所述初始挡位。
在该技术方案中,利用开合盖联动机构对联动件锁定,更加简化产品的部件数量,使得产品结构更加简化。
上述任一技术方案中,所述调压阀装置还包括:第一弹性件,与所述联动件配合;所述联动件设置在所述盖体装置上并相对于所述盖体装置可活动;当所述联动件运动以解除对所述调压阀的挡位锁定,所述联动件使所述第一弹性件变形;当所述第一弹性件弹性恢复,所述第一弹性件的弹力驱动所述联动件使所述联动件朝所述调压阀运动。
在该技术方案中,设置第一弹性件,利用第一弹性件的弹力驱动联动件,使联动件受弹力向对调压阀进行挡位锁定的位置运动,这样,在每次 对调压阀调挡之后,联动件可以自动、及时、准确地复位以对调压阀进行挡位锁定,无需用户手动锁挡,产品使用操作更加简单、方便。
例如,调压阀复位过程中,开合盖联动机构联动联动件使联动件解除对调压阀的挡位锁定后,复位驱动件驱动调压阀自动复位至初始挡位,联动件在第一弹性件弹力的作用下自动复位并将调压阀锁定于该初始挡位;再如,调压阀调挡过程中,联动件可通过压缩第一弹性件具有一定的活动量,这样,联动件可在一定程度上运动以减少调挡过程中的干涉量,调压阀被调节至相应挡位时,联动件在第一弹性件弹力的作用下自动复位并将调压阀锁定于当前挡位,使得调压阀的挡位在一定程度上维持稳定,降低跳挡风险。
上述任一技术方案中,所述联动件上设有第一限位结构,所述盖体装置限定有第二限位结构;当所述第一弹性件的弹力驱动所述联动件使所述联动件锁定所述调压阀的挡位,所述弹力使所述第一限位结构抵靠在所述第二限位结构上;当所述联动件运动以解除对所述调压阀的挡位锁定,所述第一限位结构与所述第二限位结构分开。
在该技术方案中,联动件上设置第一限位结构,利用第一限位结构和第二限位结构抵靠对联动件在弹力驱动下的运动进行限位,这样,通过当联动件运动至对调压阀的挡位进行锁定的位置时,弹力使第一限位结构和第二限位结构抵靠,使得联动件的装配具有一定的预紧力,联动件的组装和运动平稳性更好,且在满足预紧力提升平稳性的同时,通过第一限位结构和第二限位结构抵靠可以分担一部分弹力,这样可以更好地控制联动件对调压阀的锁定作用力,以更好地在满足锁定需求的同时,防止调压阀受力过大,如此以更好地保障调压阀的位置精度和运动精度,并且避免调挡阻力过大的问题。
上述任一技术方案中,所述调压阀位于所述盖体装置上,所述调压阀的至少部分相对于所述盖体装置可转动,且所述调压阀的至少部分的转动使所述调压阀的挡位改变;所述联动件与所述调压阀配合,并限制所述调压阀转动以锁定所述调压阀的挡位。
在该技术方案中,设置调压阀为转动调挡的结构,也即,转动调压阀 进行调挡,联动件通过限制调压阀转动实现对调压阀锁定挡位,对调压阀的挡位锁定简单可靠。
上述任一技术方案中,所述调压阀限定有多个配合槽,且所述调压阀的多个挡位与多个所述配合槽配套;多个所述配合槽沿所述调压阀的周向间隔地排列设置,所述联动件的一部分伸入所述配合槽内限制所述调压阀转动,使所述调压阀锁定于与所述配合槽配套的挡位。
在该技术方案中,联动件插入调压阀侧面的配合槽内,通过联动件与配合槽的侧壁干涉,能更可靠地限制调压阀转动,从而更加可靠地对调压阀锁定挡位。
其中,多个配合槽的设计可以实现对调压阀在不同挡位相应锁定,对调压阀锁定挡位更加全面可靠,且调挡过程中,联动件通过沿多个配合槽依次配合运动,可以产生段感体验,使得挡位切换通过相应的段感进行外化体现,对挡位切换的指示效果更好,且也提升了产品的操作体验。
上述任一技术方案中,所述调压阀具有侧面,所述侧面局部凹陷形成所述配合槽。
在该技术方案中,使调压阀的侧面局部凹陷形成配合槽,这样,既能满足联动件与凹陷的配合槽之间插接配合对调压阀限制转动以锁定挡位,又可以更好地兼顾调挡过程中联动件在不同配合槽之间运动和切换,这样,调挡的阻力更小,操作顺畅性更好。
上述任一技术方案中,所述配合槽的内壁面呈凹弧形;和/或所述侧面的一部分位于相邻所述配合槽之间并过渡衔接相邻所述配合槽,且相邻所述配合槽之间的所述侧面与所述配合槽的边缘呈弧形过渡。
在该技术方案中,设置配合槽的内壁面呈凹弧形,这样,联动件可以更容易地进出配合槽,不容易出现卡顿等问题,操作体验好,且对联动件的损伤也小,更利于保障产品的寿命。
设置侧面位于相邻配合槽之间的部位与配合槽的边缘之间弧形过渡,这样,联动件在不同配合槽之间切换时流畅性更好,不容易出现卡顿现象,操作体验好,且对联动件的损伤也小,更利于保障产品的寿命。
上述任一技术方案中,所述联动件上构造有凸弧面,所述凸弧面与所 述配合槽配合以锁定所述调压阀。
在该技术方案中,联动件上设置凸弧面,并使凸弧面与配合槽配合以锁定调压阀,这样,利用凸弧面,当调压阀转动进行调挡过程中,凸弧面沿调压阀的侧面滑动的阻力和损伤更小,可以更好地兼顾调挡的顺畅性并降低调压阀和联动件损伤。
上述任一技术方案中,所述盖体装置上设有排气通道,所述调压阀包括:第一转动件,相对于所述盖体装置可转动,所述复位驱动件与所述第一转动件配合并适于驱动所述第一转动件转动复位,所述联动件适于与所述第一转动件配合并限制所述第一转动件转动;第二转动件,与所述第一转动件相连并随所述第一转动件转动,所述第二转动件和所述盖体装置之间形成有传动结构,且当所述第二转动件相对于所述盖体装置转动,所述传动结构驱动所述第二转动件上下活动进行调挡;活动阀体,设置在所述第二转动件上,并相对于所述第二转动件可上下运动,且所述活动阀体上下运动打开或关闭所述排气通道。
在该技术方案中,当转动第一转动件,第一转动件会带动第二转动件随之转动,其中,第二转动件转动过程中会经由传动结构引导第二转动件上下运动,这样,通过第二转动件上下运动调节第二转动件对活动阀体的配重,使活动阀体配合在排气通道上的重量改变,实现调节对排气通道的限压压力。如,通过第二转动件上下运动进行上下位置调整,其中,根据第二转动件的上下位置变化,在一些工况下,根据具体需求可实现使第二转动件的至少部分重力施加于活动阀体并对活动阀体配重,以使第二转动件的至少部分重力与活动阀体的重力之和用于重力限压;在另一些工况下,根据具体需求也可实现使第二转动件的重力不施加于活动阀体,而利用活动阀体的至少部分重力用于重力限压;在另一些工况下,根据具体需求也可使第二转动件和活动阀体的重力均不用于重力限压,使调压阀维持打开。如此,通过使第二转动件转动,从而形成相应的限压压力调节响应,更好地满足用户的不同烹饪压力需求。
且通过本结构,实现第二转动件转动形成上下运动进行限压压力调节的目的的同时,活动阀体的限压过程基本不受影响,限压过程更加精确可 靠,且通过第二转动件以进行上下运动联动,实现配重调节,整个结构简单化,且也方便第二转动件和活动阀体整体拆出清洗,日常使用更加方便。
上述任一技术方案中,所述传动结构包括调压凸块和调压斜坡,所述调压斜坡包括斜面和弧面中的一种或多种的组合,其中,所述调压凸块和调压斜坡中的一者设置在所述第二转动件上,另一者设置在所述盖体装置上;当所述第二转动件转动,所述调压斜坡的不同位置与所述调压凸块配合,使所述第二转动件相对于所述盖体装置升高或降低。
在该技术方案中,设置传动结构包括调压凸块和调压斜坡,调压凸块与调压斜坡之间可形成类似于凸轮机构的传动作用,当调压凸块沿调压斜坡滑动的过程中,相应使得第二转动件相对于盖体装置位置升高或降低,实现利用传动结构将第二转动件的转动输入转化为第二转动件上下位移运动的输出形式,且具有结构简单,组装方便,传动顺畅性好,抗振减振效果好等优点。
上述任一技术方案中,所述传动结构包括多个所述调压斜坡;其中,相邻所述调压斜坡之间设有第一过渡面,且相邻所述调压斜坡之间经由所述第一过渡面衔接过渡;和/或多个调压斜坡之间依次升高或依次降低地排列布置;和/或多个所述调压斜坡中,位于两端的两个所述调压斜坡分别衔接有第二过渡面;和/或多个所述调压斜坡中,位置最低的所述调压斜坡的一端衔接有第二过渡面,当所述调压凸块位于位置最低的所述调压斜坡所衔接的所述第二过渡面上,所述调压阀相应处于所述初始挡位。
在该技术方案中,调压凸块沿调压斜坡滑动使得调压阀自相邻挡位中的一者向另一者变挡,实现挡位调节,其中,设计多个调压斜坡,且在调压斜坡之间衔接有第一过渡面进行过渡,这样,调压凸块运动至调压斜坡之间的第一过渡面上时,相应完成一次挡位变换,且第一过渡面可以提供停靠作用以利于调压凸块维持稳定,使调压凸块不容易沿调压斜坡倒溜,挡位调节精度更高。
且这样的结构设计可以更好地搭配联动件与配合槽配合的锁定结构,例如,可以使联动件进出配合槽的过程中,调压凸块位于第一过渡面上,联动件沿配合槽之间的侧面滑动的过程中,调压凸块位于调压斜坡上,这 样,联动件进出配合槽的阻力过程和调压凸块与调压斜坡配合的阻力过程有效分散开,结构之间的包容性和适配性更好,且运动过程中不会出现阻力集中的问题,更好地保障调挡过程的顺畅性,且也有减小了调挡作用力需求,用户操作体验可更好。
设置多个调压斜坡之间依次升高或依次降低的排列布置,这样,沿一个方向转动第一转动件时,第二转动件呈位置逐渐升高或位置逐渐降低的运动过程,实现依次挡位调节,不会出现跨挡,指示性更好,用户操作更加简单方便,且调压阀复位过程中也可以更顺利地一次性复位至初始挡位,不会卡在中途,从而提升调压阀装置开盖自动复位的可靠性。
值得说明的是,对于上述多个调压斜坡之间依次升高或依次降低的排列布置,应该宏观地理解为多个调压斜坡之间在整体趋势上是逐渐升高排列或降低排列的,并不排斥调压斜坡上或调压斜坡之间具有某个小突起等结构而导致调压凸块在局部某个位置处有一定起伏跳动的情况。
也即,应当理解为,通过限定多个调压斜坡之间依次升高或依次降低的排列布置,应当包容理解为,调压凸块运动过程中,在多个调压斜坡的导向引导的整体趋势上,调压凸块的运动是逐渐升高或逐渐降低的,但是,也允许出现调压凸块的整个运动过程中在某一位置处具有小幅度突跳起伏的情况。
设置多个调压斜坡中,位于两端的两个调压斜坡分别衔接有第二过渡面,这样,调压凸块经过端部的调压斜坡后,可以运动至第二过渡面上,通过第二过渡面的停靠作用以利于调压凸块维持稳定,使调压凸块不容易沿调压斜坡倒溜,挡位调节精度更高。
设置多个调压斜坡中,位置最低的调压斜坡的一端衔接有第二过渡面,当调压凸块位于位置最低的调压斜坡所衔接的第二过渡面上,调压阀相应处于初始挡位,通过第二过渡面的停靠作用以利于调压凸块在初始挡位维持稳定,使调压凸块不容易沿调压斜坡倒溜,对调压阀在初始挡位的锁定作用更好。
上述任一技术方案中,所述第一转动件和所述第二转动件中的一者设有导向筋,另一者设有凹槽,所述导向筋伸入所述凹槽内并与所述凹槽啮 合使得所述第二转动件随所述第一转动件转动,且所述导向筋沿所述凹槽可滑动,使得所述第一转动件与所述第二转动件之间可上下活动。
在该技术方案中,利用导向筋和凹槽啮合,且导向筋沿凹槽可上下滑动,既实现了第一转动件带动第二转动件转动的传动连接,也使得第二转动件相对于第一转动件可上下滑动,以供第二转动件通过上下运动进行挡位调节,且该结构中,导向筋沿凹槽滑动可形成导向作用,这样,第二转动件的上下运动方向更准确,压力控制更加准确可靠,且导向筋与凹槽配合,具有结构简单、组装方便的优点。
上述任一技术方案中,所述第一转动件呈环形并套装在所述第二转动件的外侧。
在该技术方案中,设置第一转动件呈环形并套装在第二转动件的外侧,这样,第一转动件与第二转动件之间嵌套形成相互定位,保障部件之间装配精度的同时,无需对第一转动件和第二转动件分别定位组装,结构更简化,装配也更方便。

在该技术方案中,当转动调压拨动件,调压拨动件会带动外阀体随之转动,其中,外阀体转动过程中会进行上下运动,这样,通过外阀体上下运动调节外阀体对内阀体的配重,使内阀体配合在排气通道上的重量改变,实现调节对排气通道的限压压力。如,通过外阀体上下运动进行上下位置调整,其中,根据外阀体的上下位置变化,在一些工况下,根据具体需求可实现使外阀体的至少部分重力施加于内阀体并对内阀体配重,以使外阀体的至少部分重力与内阀体的重力之和用于重力限压;在另一些工况下,根据具体需求也可实现使外阀体的重力不施加于内阀体,而利用内阀体的至少部分重力用于重力限压;在另一些工况下,根据具体需求也可使外阀体和内阀体的重力均不用于重力限压,使阀组件维持打开。如此,通过使外阀体转动,从而形成相应的限压压力调节响应,更好地满足用户的不同烹饪压力需求。

且通过变形部的设计使得第一限位部与第二限位部之间装卸过程中的损伤更小,可更好地保障产品反复装卸不损坏,更好地保障产品使用寿命。
另外,本申请提供的上述技术方案中的限压阀还可以具有如下附加技术特征:
上述技术方案中,所述第一阀体或所述第二阀体包括:阀本体;柔性件或弹性件,所述变形部由柔性件或弹性件构成,所述柔性件或弹性件设置在所述阀本体上并且至少一部分相对于所述阀本体的表面凸起,所述柔性件或弹性件相对于所述阀本体的表面凸起的部位形成所述第一限位部或所述第二限位部。
在该技术方案中,设置柔性件或弹性件与阀本体,使柔性件或弹性件设在阀本体上且柔性件或弹性件相对阀本体表面凸起的部位用于构造第一限位部或第二限位部,这样,实现获得至少一部分为变形部的第一限位部或第二限位部,以实现第一阀体与第二阀体柔性或弹性连接便于装卸的目的的同时,产品结构更加简化,且也更方便于柔性件或弹性件的更换以及随产品型号的调整,这样,利用柔性件的可替换性可克服老化影响,且也更利于产品结构在不同型号的限压阀之间适用,更利于产品的推广。
上述任一技术方案中,所述阀本体设有容置槽,所述柔性件或弹性件的一部分容置于所述容置槽内,另一部分伸出所述容置槽并相对于所述阀本体的表面凸起。
在该技术方案中,阀本体设有容置槽,柔性件或弹性件部分容置于容置槽实现装配,产品的装配定位更加方便容易,产品组装更高效,且容置槽可对柔性件形成限位作用,防止柔性件受力偏位等问题,从而更利于保 障第一阀体与第二阀体之间经由第一限位部和第二限位部实现的限位精度。
上述任一技术方案中,所述第二阀体的至少一部分套设在所述第一阀体内,所述第一限位部和所述第二限位部中的一者的至少一部分为所述变形部且所述变形部由柔性件构成,另一者包括凸扣。

上述任一技术方案中,所述凸扣上限定有适于引导所述变形部与所述凸扣卡接装配的卡接斜面。
在该技术方案中,凸扣设置卡接斜面,这样,第一限位部与第二限位部之间装配的过程中,变形部不容易被刮伤,从而更好地保障产品的质量和使用寿命。
上述任一技术方案中,所述第一阀体设有限位凸起,所述限位凸起与所述第一限位部之间间隔地分布,使所述限位凸起与所述第一限位部之间形成适于供所述第二限位部活动的空间,所述第二限位部活动设置于所述空间内。
在该技术方案中,设置第二限位部限位于限位凸起与第一限位部之间,并在限位凸起与所述第一限位部之间可活动,这样,利用第二限位部的活动自由度,既满足了第一阀体与第二阀体之间的相对活动需求,利用第一限位部和限位凸起对第二限位部的限位作用,又可以很好地满足第一阀体与第二阀体之间的防脱需求,实现第一阀体与第二阀体之间良好地活动连接装配,且产品的装卸更加方便,如拆卸时,施加外力使第二限位部从第一限位部位置挤出即可,装配时,施加外力使第二限位部从第一限位部位置挤入第一限位部与限位凸起之间即可,使用简单方便。
上述任一技术方案中,所述第一阀体限定有容纳孔,所述限位凸起和所述第一限位部分别相对于所述容纳孔的内壁面凸起,且所述限位凸起与所述第一限位部沿所述容纳孔的轴向间隔地分布;所述第二阀体的至少一部分位于所述容纳孔内,所述第二阀体沿所述容纳孔活动使所述第二限位 部往返于所述限位凸起与所述第一限位部之间。
在该技术方案中,使第二阀体的至少一部分容置于容纳孔内,这样,可以对第二阀体形成径向限位。使限位凸起与第一限位部沿容纳孔的轴向间隔地分布,这样,第二限位部被限位于限位凸起与第一限位部之间,可以限制第一阀体与第二阀体之间的轴向活动量,并防止两者脱离,第一阀体与第二阀体之间的活动连接可靠性更好,且产品的装卸更加方便,如拆卸时,施加外力使第二阀体沿容纳孔自第一限位部位置挤出即可,装配时,施加外力使第二阀体沿容纳孔自第一限位部位置挤入即可,使用简单方便。
上述任一技术方案中,所述限压阀用于具有排气通道的盖体,其中,所述第二阀体被配置为适于与所述排气通道配合以打开或关闭所述排气通道;所述第一限位部与所述限位凸起上下间隔分布;所述第一阀体与所述第二阀体之间适于上下相对运动,且所述第一阀体被配置为通过上升或下降使所述第二限位部与所述限位凸起或所述第一限位部抵靠或分开,以改变所述第二阀体配合到所述排气通道上的重量。
在该技术方案中,设置第一限位部与限位凸起上下间隔分布,这样,通过第二限位部与第一限位部和/或限位凸起的配合状态切换,可以更精确地调节第二阀体配合到排气通道上的重量,使得限压压力控制更加精准。以第一限位部在下,限位凸起在上为例说明,当第一阀体位置较低,使得限位凸起搭靠在第二限位部上,第一阀体的重量施加于第二阀体,这样,第二阀体施加于排气通道的重量较大,限压压力相应较大(例如为高压);当第一阀体位置上升,第二限位部与限位凸起分开并且与第一限位部分开,第一阀体的重量不会施加于第二阀体,这时施加于排气通道的重量为第二阀体的重力,限压压力相应降低(例如为低压);当第一阀体继续上升至第二限位部与第一限位部抵靠,第二阀体的重量不会完全作用到排气通道上或使第二阀体完全离开排气通道,这时施加于排气通道的重量小于第二阀体的重力或施加于排气通道的重量为零,限压压力进一步降低或为零。
通过以上过程可以理解,第二限位部上下运动来配合上下分布的限位凸起和第一限位部,这样,对第二阀体施加于排气通道的重量的调控不会有额外的干扰,限压压力调节更加精确。
上述任一技术方案中,所述第一限位部的至少一部分为变形部,所述第一限位部位于所述限位凸起的下侧。
在该技术方案中,设置第一限位部的至少一部分为变形部且位于限位凸起的下侧,这样,第二阀体承受内压浮起时,是利用限位凸起来与第二限位部配合进行限位,可以更好地防止第二阀体被顶出,产品可靠性更高。
上述任一技术方案中,所述限压阀还包括:调压拨动件,与所述第一阀体可装卸地连接,并适于驱动所述第一阀体运动。
在该技术方案中,设置调压拨动件用于驱动第一阀体运动,如通过调压拨动件来联动第一阀体进行调压和复位,这样,外力(如调压驱动力或复位驱动力)基本作用于调压拨动件上,可以理解,外力的大小、方向等具有不可控性,如此设计可使得施加于第一阀体的力的大小、方向的可控性更好,这样第一阀体的限压可靠性和精准性更易于保障,提升产品的压控精度。
其中,设计调压拨动件与第一阀体可拆卸连接,这样,方便于限压阀进一步拆解,从而更方便与限压阀的拆洗,产品使用卫生性更好。
上述任一技术方案中,所述调压拨动件和所述第一阀体中的一者设有导向筋,另一者设有凹槽,所述导向筋伸入所述凹槽内使所述调压拨动件与所述第一阀体之间啮合传动,其中,所述导向筋与所述凹槽之间可滑动,以供所述第一阀体相对于所述调压拨动件活动。

具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点,下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是,在不冲突的情况下,本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请,但是,本申请还可以采用其他不同于在此描述的其他方式来实施,因此,本申请的保护范围并不受下面公开的具体实施例的限制。
下面,参照图1至图72描述根据本申请一些实施例所述的盖体、盖体组件、限压阀及烹饪设备。
如图1所示,本申请第一方面的实施例提供了一种盖体,包括:调压阀装置10、开合盖联动机构20和盖体装置30。
其中,当盖体装置30开盖,盖体装置30联动开合盖联动机构20,并通过开合盖联动机构20联动调压阀装置10,使调压阀装置10的挡位复位至初始挡位。
本申请上述实施例提供的盖体,当盖体装置30开盖,盖体装置30联动开合盖联动机构20,并通过开合盖联动机构20联动调压阀装置10,使调压阀装置10的挡位复位至初始挡位,这样则实现了开盖时调压阀装置10自动复位,无需用户对调压阀装置10手动归挡,使用操作更加方便、简洁,同时避免了用户使用调挡功能时忘记对调压阀装置10复位引起的下一次烹饪挡位不对带来的不良影响,如处于排气挡位发生水烧干等风险和危害,提升产品的安全性。
更详细地,盖体具体用于烹饪设备,例如,用于电饭煲、压力锅、电蒸锅、蒸汽饭煲等烹饪设备,盖体配置为与烹饪设备的烹饪锅80盖合,并适于与烹饪锅80合围出烹饪腔。
可以理解,调压阀装置10为多挡位的调压装置,也即,调压阀装置 10具有多个挡位,每个挡位分别配套有限压压力,调压阀装置10配置为将烹饪腔内的压力限制在当前挡位所配套的限压压力以下。
其中,初始挡位为多个挡位中的一者。更详细举例而言,初始挡位可以为无压挡位或高压挡位,换言之,无压挡位也可称之为零压挡位或常压挡位。
实施例一
如图2和图4所示,本实施例提供了一种盖体,包括:调压阀装置10、开合盖联动机构20和盖体装置30。
其中,调压阀装置10包括调压阀100、联动件200和复位驱动件(具体可参照第二弹性件301进行理解)。
具体地,调压阀100具有多个挡位,且多个挡位中的一者为初始挡位。调压阀100用于调挡和限压,具体用于将烹饪腔内的压力限制在当前挡位所配套的限压压力以下。
联动件200适于锁定调压阀100的挡位。这样,在将调压阀100调至相应挡位后,利用联动件200对调压阀100锁定挡位,可以使得调压阀100的挡位维持稳定可靠,防止调压阀100在非调节情形下跳挡,产品限压功能更精准可靠。
其中,联动件200用于与开合盖联动机构20配合。具体地,当盖体装置30开盖,盖体装置30联动开合盖联动机构20,并通过开合盖联动机构20联动联动件200,使联动件200解除对调压阀100的挡位锁定。
复位驱动件与调压阀100配合,且当联动件200解除对调压阀100的挡位锁定,复位驱动件驱动调压阀100至初始挡位。
如此,当盖本体31开盖,可以形成如下传动过程:
盖体装置30联动开合盖联动机构20-开合盖联动机构20联动联动件200运动,使联动件200解除对调压阀100的挡位锁定-复位驱动件驱动调压阀100至初始挡位。
利用上述传动过程,形成了盖本体31开盖-调压阀100至初始挡位的自动触发响应过程。无需用户对调压阀装置10手动归挡,使用操作更加方便、简洁,同时避免了用户使用调挡功能时忘记对调压阀装置10复位引起 的水烧干等风险和危害,提升产品的安全性。
且本结构中,驱动调压阀100复位的动力来自于复位驱动件,这样可以有效保障开合盖联动机构20的精准性不受调压阀100干扰,保证产品的开合盖功能稳定、可靠,有效保障产品安全。
进一步地,如图2所示,调压阀装置10还包括第一弹性件400。具体地,第一弹性件400与联动件200配合;联动件200设置在盖体装置30上并相对于盖体装置30可活动;当联动件200运动以解除对调压阀100的挡位锁定,联动件200使第一弹性件400变形;当第一弹性件400弹性恢复,第一弹性件400的弹力驱动联动件200朝调压阀100运动,使联动件200锁定调压阀100的挡位。这样,在每次对调压阀100调挡之后,联动件200可以自动、及时、准确地对调压阀100进行挡位锁定,无需用户手动锁挡,产品使用操作更加简单、方便。
详细举例地,如图2所示,联动件200具体设置在盖体装置30的面盖32内侧,并相对于面盖32在第一位置与第二位置之间可活动,联动件200在第一位置与调压阀100配合以锁定调压阀100的挡位(如图2和图5所示),联动件200在第二位置解除对调压阀100的挡位锁定。其中,第一弹性件400与联动件200抵靠或相连,当联动件200在第二位置,联动件200拉伸过压缩第一弹性件400使第一弹性件400变形,当第一弹性件400弹性恢复,驱动联动件200向第一位置运动。
这样,调压阀100复位过程中,开合盖联动机构20联动联动件200使联动件200至第二位置以解除对调压阀100的挡位锁定后,复位驱动件驱动调压阀100自动复位至初始挡位,当开合盖联动机构20对联动件200的作用力撤去后,联动件200在第一弹性件400弹力的作用下自动复位至第一位置,并将调压阀100锁定于该初始挡位;再如,调压阀100调挡过程中,联动件200在第一位置和第二位置之间往复运动从而具有一定的活动量,这样,对调压阀100调节挡位时,联动件200向第二位置运动可以对调压阀100的调节挡位运动进行避让,使联动件200在一定程度上减少调挡过程中对调压阀100的干涉量,调压阀100被调节至相应挡位后,联动件200在第一弹性件400弹力的作用下自动复位至第一位置,并将调压阀 100锁定于当前挡位,使得调压阀100的挡位在一定程度上维持稳定,降低跳挡风险。
更详细地,如图2所示,第一弹性件400为伸缩弹簧,其一端与联动件200抵靠,另一端与盖体装置30抵靠,例如具体与盖体装置30的面盖32抵靠。当然,本设计并不局限于此,在其他实施例中,第一弹性件400也可采用为弹片、弹性硅胶等。
在某些具体实施例中,如图2和图9所示,为对第一弹性件400的伸缩进行导向以提升第一弹性件400的变形效果,在联动件200上限定有导向杆240,第一弹性件400的至少一部分套装在导向杆240的外侧,使得第一弹性件400沿导向杆240进行伸缩变形。
更进一步地,如图2、图5和图9所示,联动件200上设有第一限位结构210,盖体装置30限定有第二限位结构3205;当联动件200运动以解除对调压阀100的挡位锁定(例如当联动件200位于第二位置),第一限位结构210与第二限位结构3205分开。
当第一弹性件400的弹力驱动联动件200使联动件200锁定调压阀100的挡位(例如当联动件200位于第一位置),弹力使第一限位结构210抵靠在第二限位结构3205上。这样,使得联动件200的装配具有一定的预紧力,联动件200的组装和运动平稳性更好,这样可以防止调挡过程中调压阀100带动联动件200导致联动件200偏位,使得联动件200位置精度更加可靠。且在满足预紧力提升平稳性的同时,通过第一限位结构210和第二限位结构3205抵靠可以分担一部分弹力,这样可以更好地控制联动件200对调压阀100的锁定作用力,以更好地在满足锁定需求的同时,防止调压阀100受力过大,如此以更好地保障调压阀100的位置精度和运动精度,并且避免调挡阻力过大的问题。
更详细地,如图9所示,联动件200具体轴体,轴体上限定有轴肩结构,轴肩结构作为第一限位结构210。如图5所示,盖体上设有复位引导槽3212,联动件200的一部分穿过复位引导槽3212与调压阀100配合以对调压阀100锁定挡位,且复位引导槽3212同时作为第二限位结构3205,联动件200的第一限位结构210与复位引导槽3212抵靠配合对联动件200 限位。结构简单,加工方便,进一步强化联动件200的稳定性。
进一步地,如图5所示,盖体装置30限定有轨道槽3210,联动件200的一部分位于轨道槽3210内,且联动件200的运动经由轨道槽3210导向和限位,可以使得联动件200的运动更加精准,且使得联动件200与调压阀100的配合更加精准,更进一步强化了联动件200对调压阀100的限位可靠性,从而提升对调压阀100的挡位锁定的可靠性。
更进一步地,如图5所示,轨道槽3210与第二限位结构3205之间具有间距,可以进一步提升对联动件200的导向效果,且可以防止联动件200以第二限位结构3205为支点发生偏转,进一步提升联动件200的装配可靠性和稳定性。
在某些实施例中,如图2所示,其中,调压阀100位于盖体装置30上,调压阀100的至少部分相对于盖体装置30可转动,且调压阀100的至少部分转动使调压阀100的挡位改变。采用旋转调压的调压阀100,具有调压操作简单、方便,且这样的结构在不浪费产品空间的前提下,可拥有更大的调节行程,这样,可以形成更多的挡位,且也利于对挡位的精细化调控。
联动件200与调压阀100配合,并限制调压阀100的至少部分转动以锁定调压阀100的挡位。联动件200通过限制调压阀100转动实现对调压阀100锁定挡位,对调压阀100的挡位锁定简单可靠。
进一步地,如图5所示,调压阀100限定有多个配合槽102,且调压阀100的多个挡位与多个配合槽102配套;多个配合槽102沿调压阀100的周向间隔地排列设置,联动件200的一部分伸入配合槽102内限制调压阀100转动,使调压阀100锁定于与配合槽102配套的挡位。该结构中,通过联动件200与配合槽102的侧壁干涉,能更可靠地限制调压阀100转动,从而更加可靠地对调压阀100锁定挡位。
其中,多个配合槽102的设计可以实现对调压阀100在不同挡位相应锁定,对调压阀100锁定挡位更加全面可靠,且调挡过程中,联动件200通过沿多个配合槽102依次配合运动,可以产生段感体验,使得挡位切换通过相应的段感进行外化体现,对挡位切换的指示效果更好,且也提升了产品的操作体验。
进一步地,如图5和图10所示,调压阀100具有侧面101,侧面101局部凹陷形成配合槽102。这样,既能满足联动件200与凹陷的配合槽102之间插接配合对调压阀100限制转动以锁定挡位,又可以更好地兼顾调挡过程中联动件200在不同配合槽102之间运动和切换,这样,调挡的阻力更小,操作顺畅性更好。
在某些具体实施例中,如图5所示,配合槽102的内壁面呈凹弧形。这样,联动件200可以更容易地进出配合槽102,不容易出现卡顿等问题,操作体验好,且对联动件200的损伤也小,更利于保障产品的寿命。
在某些具体实施例中,如图5所示,侧面101的一部分位于相邻配合槽102之间并过渡衔接相邻配合槽102,且相邻配合槽102之间的侧面101与配合槽102的边缘呈弧形过渡103。这样,联动件200在不同配合槽102之间切换时流畅性更好,不容易出现卡顿现象,操作体验好,且对联动件200的损伤也小,更利于保障产品的寿命。
在某些具体实施例中,如图9所示,联动件200上构造有凸弧面220,凸弧面220与调压阀100的配合槽102配合以锁定调压阀100。这样,利用凸弧面220,当调压阀100转动进行调挡过程中,凸弧面220沿调压阀100的侧面101滑动的阻力和损伤更小,可以更好地兼顾调挡的顺畅性并降低调压阀100和联动件200损伤。
更详细地,如图9所示,联动件200的轴体轴向的一端的端面限定为该凸弧面220,联动件200以凸弧面220部位与调压阀100的侧面101及配合槽102配合,具体地,调压阀100转动时,凸弧面220沿侧面101滑动并在不同配合槽102之间切换,实现对不同挡位锁定。
在某些具体实施例中,如图2和图3所示,盖体装置30上限定有排气通道111。排气通道111用于与烹饪腔连通,当排气通道111打开,供烹饪腔排气,当排气通道111关闭,使得烹饪腔在排气通道111处密封。
其中,如图2和图3所示,调压阀100包括第一转动件120和阀体组件。
如图2所示,第一转动件120相对于盖体装置30可转动,复位驱动件与第一转动件120配合并适于驱动第一转动件120转动复位,联动件200 适于与第一转动件120配合并限制第一转动件120转动。
阀体组件用于打开或封堵排气通道,其中,第一转动件120与阀体组件相连,且第一转动件120配置为通过转动联动阀体组件,使阀体组件对排气通道的限压压力改变。其中,复位驱动件与第一转动件120配合并适于驱动第一转动件120转动复位,联动件200适于与第一转动件120配合并限制第一转动件120转动。
更具体地,阀体组件包括相互连接的第二转动件130和活动阀体140。第一转动件120与第二转动件130相连,第一转动件120转动时带动第二转动件130相对排气通道111上升或下降,以改变阀体组件配合在排气通道111上的重量。
活动阀体140上设有封堵部,封堵部用于封闭或打开排气通道111。活动阀体140相对于第二转动件130可上下运动,且活动阀体140上下运动打开或关闭排气通道111。
详细举例而言,盖体装置上设有阀芯110,阀芯110内限定有排气通道111。具体地,当封堵部压在阀芯110上,封堵部对阀芯110的排气通道111密封,当活动阀体140被顶起使得封堵部打开排气通道111,烹饪腔可沿排气通道111排气。当然,本设计并不局限于此,在其他实施例中,排气通道111也可经由盖体装置的锅盖33、内盖等上的排气孔限定出。
其中,以调压阀100具有无压挡/排气挡、低压挡和高压挡,并可在无压挡/排气挡、低压挡和高压挡之间切换为例进行详细举例说明:
第一转动件120旋转的同时,第二转动件130实现旋转并上升,第二转动件130上升后,第二转动件130的重量被盖体装置的面盖承受,没有压在阀芯110的排气口上,故此时只有活动阀体140的重量压在阀芯110的排气口处,实现调压阀100切换为低压挡位,故此时烹饪设备的烹饪腔内的压力较低时就可以将活动阀体140推动而排气,实现低压烹饪。
当第一转动件120继续旋转,第二转动件130实现旋转并继续上升,第二转动件130将活动阀体140顶起,例如,第二转动件130的柔性件(具体如硅胶体、橡胶体等)将活动阀体140顶起,第二转动件130和活动阀体140整体离开阀芯110,第二转动件130和活动阀体140均没有压在阀 芯110的排气口上,排气通道111打开,实现调压阀100切换为无压挡位或排气挡位,实现无压烹饪或排气。
当第二转动件130在第一转动件120的带动下复位时,第二转动件130下降,第二转动件130压在活动阀体140上,具体如,第二转动件130的限位凸起压在活动阀体140的限位块上,从而使得活动阀体140和第二转动件130的重量都压在阀芯110的排气口上,实现调压阀100切换为高压挡位,故此时烹饪设备的烹饪腔内的压力要达到较高才可以将活动阀体140推动而排气,实现高压烹饪,由此通过改变阀体组件压在阀芯110的排气口上的重量,从而实现调节烹饪设备内的烹饪腔压力变化的目的。
进一步地,如图11所示,第二转动件130和盖体装置30之间形成有传动结构,其中,当所述第二转动件130相对于盖体装置30转动,第二转动件130与盖体装置30之间具体经由传动结构进行传动,使第二转动件130上下活动进行调挡。
举例而言,如图16所示,传动结构包括调压凸块3216(调压凸块3216具体为支撑柱)和调压斜坡(具体参照附图中的第一调压斜坡534和/或第二调压斜坡535进行理解),调压斜坡包括斜面和弧面中的一种或多种的组合,其中,调压凸块3216和调压斜坡中的一者设置在第二转动件130上,另一者设置在盖体装置30上;当第二转动件130转动,调压凸块3216沿调压斜坡滑动,其中,调压斜坡的不同位置与调压凸块3216配合,使第二转动件130相对于盖体装置30升高或降低。
这样,调压凸块3216与调压斜坡之间可形成类似于凸轮机构的传动作用,当调压凸块3216沿调压斜坡滑动的过程中,相应使得第二转动件130相对于盖体装置30位置升高或降低,实现利用传动结构将第二转动件130的转动输入转化为第二转动件130上下位移运动的输出形式,且具有结构简单,组装方便,传动顺畅性好,抗振减振效果好等优点。
进一步地,如图11所示,第二转动件130上限定有调压面530,传动结构形成为调压面530的一部分。更具体地,调压面530包括第一级调压平面531、第二级调压平面532、第三级调压平面533、第一调压斜坡534和第二调压斜坡535,第一调压斜坡534过渡在第一级调压平面531与第 二级调压平面532之间,且第一调压斜坡534自第一级调压平面531向第二级调压平面532位置升高,第二调压斜坡535自第二级调压平面532向第三级调压平面533位置升高。
另外,如图24,第一转动件120设有侧面101,且侧面上限定有3个配合槽102,分别为配合槽102a、配合槽102b、配合槽102c。配合槽102a对应高压挡位,配合槽102b对应低压挡位,配合槽102c对应无压挡位或排气挡位。
当调压凸块3216抵靠于第三级调压平面533上,如图17和图18所示,调压阀100处于初始挡位(也即高压挡位),第二转动件130的位置最低,且联动件200的凸弧面220配合于对应高压挡位的配合槽102a内以锁定第一转动件120,烹饪腔内进行高压烹饪。
当调压凸块3216抵靠于第二级调压平面532上,如图19所示,第二转动件130被抬高且其重量支撑在盖体装置30上,调压阀100处于低压挡位,且联动件200的凸弧面220配合于对应低压挡位的配合槽102b内以锁定第一转动件120,烹饪腔内进行低压烹饪。
当调压凸块3216抵靠于第一级调压平面531上,如图20所示,第二转动件130继续被抬高并带动活动阀体140一起上升,调压阀100处于无压挡位或排气挡位,且联动件200的凸弧面220配合于对应无压挡位或排挡位的配合槽102c内以锁定第一转动件120,阀体组件位置最高,烹饪腔内进行无压烹饪或排气。
通过本方案,且通过本结构,实现第二转动件130转动形成上下运动进行限压压力调节的目的的同时,活动阀体140的限压过程基本不受影响,限压过程更加精确可靠,且通过阀体组件转动以进行上下运动联动,实现阀体组件配重调节,整个结构简单化,且也方便阀体组件整体拆出清洗,日常使用更加方便。
当然,本设计并不局限于此,在其他实施例中,也可采用螺纹结构实现第二转动件转动同时形成上下运动的目的。
在某些具体实施例中,第一转动件120与第二转动件130之间的连接使得第二转动件130随第一转动件120转动,并使得第二转动件130相对 于第一转动件120可上下运动。
例如,第一转动件120具有环形体,并围成上下贯穿的安装孔,第二转动件130位于该安装孔。第二转动件130的侧壁的外表面和环形体侧壁的内表面中一者设有导向筋134,另一者设有凹槽121,导向筋134沿上下方向延伸设置,凹槽121套装在导向筋134的外侧形成导向筋134与凹槽121啮合,凹槽121为上下延伸设置的滑槽,导向筋134沿凹槽121可上下滑动,这样,既满足第一转动件120与第二转动件130之间转动联动,也使得第二转动件130与第一转动件120之间可上下相对运动。使得第一转动件120转动时,第二转动件130可相对于第一转动件120上升或下降。
更详细地,如图10所示,第一转动件120呈环形,并围成上下贯穿的安装孔,第二转动件130位于该安装孔内并可沿该安装孔上下活动。当然,本实施例并不局限于此,在其他实施例中,根据需求也可设计第一转动件随第二转动件上下运动。或者,在另一些实施例中,根据需求也可设计第一转动件为第二转动件的一部分,如第一转动件与第二转动件形成为一体。
进一步地,如图10所示,第一转动件120上设有拨钮122。用户通过拨钮122驱动第一转动件120转动进行调挡,产品操作可更加方便、简单。
进一步地,如图3、图5和图7所示,盖体装置30具有面盖32,面盖32上设有安装槽3201。如图3所示,第一转动件120至少部分位于安装槽3201内。
其中,如图7和图10所示,安装槽3201的侧壁和第一转动件120中的一者上设有旋转导槽123,另一者上设有旋转限位凸块3202,旋转限位凸块3202伸入旋转导槽123内并沿旋转导槽123滑动,且旋转限位凸块3202与旋转导槽123配合限制第一转动件120离开安装槽3201。
更详细地,旋转导槽123沿其所在的安装槽3201侧壁或第一转动件120的周向延伸,旋转限位凸块3202伸入旋转导槽123内,这样,第一转动件120转动的过程中,旋转限位凸块3202沿旋转导槽123滑动。
其中,旋转导槽123具有上侧壁和下侧壁,上侧壁与下侧壁之间间隔并围成供旋转限位凸块3202滑动运动的空间。旋转限位凸块3202位于上侧壁与下侧壁之间,利用上侧壁和下侧壁对旋转限位凸块3202限位,限制 第一转动件120脱离安装槽3201。
更进一步地,安装槽3201的侧壁和第一转动件120中的一者上沿周向排列布置有多个旋转导槽123,另一者上相应设有多个旋转限位凸块3202(具体例如图7所示,安装槽3201的侧壁上设有3个旋转限位凸块3202),多个旋转限位凸块3202与多个旋转导槽123之间一一对应配合,这样,形成对第一转动件120周向多个位置进行支撑和限位,进一步提升第一转动件120的装配稳定性。
当然,本设计并不局限于此,在其他实施例中,也可设计1个旋转限位凸块3202与1个旋转导槽123配合。或者,根据需求,也可设计2个、4个、5个、6个等旋转限位凸块3202,旋转导槽123的数量根据旋转限位凸块3202的数量相应设计。
进一步地,如图7所示,盖体装置30限定有多个调压凸块3216,第二转动件130上设有多个调压面530,且调压面530与调压凸块3216之间一对一配套。对第二转动件130支撑更平稳。
具体例如图7所示,盖体装置30的面盖32上设有安装槽3201,安装槽3201内设有调压凸块3216,调压凸块3216为相对于安装槽3201的内底面凸起的凸筋或支撑柱。调压凸块3216的数量为3个,且3个调压凸块3216沿安装槽3201的周向间隔地排列布置,以对第二转动件130更平稳地支撑。当然,调压凸块3216的数量并不局限为3个,在其他实施例中,调压凸块3216的数量也可设计为1个、2个、4个、5个甚至更多。
进一步地,如图12、图13和图14所示,第二转动件130和活动阀体140中的一者设有第三限位结构135,另一者设有限位块141,第三限位结构135包括两个间隔分布的限位凸起1351,限位块141伸入两个限位凸起1351之间,且活动阀体140上下运动使限位块141往返于两个限位凸起1351之间。这样可以防止活动阀体140脱离第二转动件130,有效保障第二转动件130与活动阀体140之间连接及相对位置准确性,有效保障调挡功能准确、可靠。
更进一步地,两个限位凸起1351中的至少一个为柔性件1352。这样,第二转动件130与活动阀体140之间形成柔性连接,更方便产品的装卸。
详细举例地,如图12所示,柔性件1352与第二转动件130为分体部件。例如,第二转动件130上设有容置槽,柔性件1352的一部分容置于安容置槽,并通过容置槽限位实现柔性件1352装配在第二转动件130上。柔性件1352的另一部分伸出容置槽,并自第二转动件130的表面凸起,其中,柔性件1352相对于第二转动件130的表面凸起的部位作为一个限位凸起1351,该柔性件1352与第二转动件130的表面上的另一限位凸起1351之间间隔分布限定出供限位块141活动的空间,活动阀体140相对于第二转动件130上下运动,使得限位块141在柔性件1352与限位凸起1351之间来回运动。
更详细例如,柔性件1352为硅胶件。
在某些具体实施例中,更进一步地,开合盖联动机构20包括自锁滑块21,自锁滑块21设置在盖体装置30上,且盖体装置30开盖联动自锁滑块21运动,并通过自锁滑块21联动调压阀装置10的联动件200,使联动件200解除对调压阀装置10的调压阀100的挡位锁定。
更进一步地,自锁滑块21上设有止挡部22,联动件200上限定有适配止挡部22的止挡结构230;当盖体装置30开盖,止挡部22作用于止挡结构230并驱动联动件200运动,使联动件200解除对调压阀100的挡位锁定。
进一步举例而言,止挡部22为设置在自锁滑块上的凸板或卡钩,止挡结构230为止挡凸块,止挡凸块的至少一部分朝自锁滑块延伸,当盖体装置30开盖,凸板或卡钩拉动止挡凸块,使联动件200朝远离调压阀100的方向运动。
另外,盖体装置30上设有轨道槽3210,联动件200的一部分位于轨道槽3210内,且轨道槽3210适于对联动件200的运动导向。
进一步地,盖体装置30上还设有复位引导槽3212,复位引导槽3212位于轨道槽3210与调压阀100之间,联动件200的一端自复位引导槽3212穿过与调压阀100配合以对调压阀100锁定,其中,复位引导槽3212与轨道槽3210之间间隔地分布。
更进一步地,盖体装置30的面盖或内盖上形成有第二限位结构3205, 第二限位结构3205具体包括挡筋且挡筋围设出复位引导槽3212,联动件200的一部分穿设在复位引导槽3212内,联动件200上设有轴肩,轴肩作为第一限位结构并适于与复位引导槽3212两侧的第二限位结构3205抵靠或分离以对联动件200限位。
在某些具体实施例中,复位驱动件包括第二弹性件301,具体为弹簧,当然,根据需求可以为弹片、弹性橡胶等。
第二弹性件301与盖体装置30及调压阀100抵靠配合,调压阀100运动联动第二弹性件301使第二弹性件301变形,第二弹性件301弹性恢复时带动调压阀100复位。
进一步地,第二弹性件301沿调压阀100的周向延伸设置呈弧形。
更详细地,如图7和图5所示,盖体装置30具有面盖32,面盖32上设有装配槽3206,装配槽3206沿调压阀100的周向延伸设置呈弧形。第二弹性件301容置于装配槽3206内并沿装配槽3206伸缩。一方面,装配槽3206的设置更方便第二弹性件301的安装和定位,另一方面,装配槽3206的导向作用可以良好地引导第二弹性件301的变形方向,这样,第二弹性件301的变形效果更好,不容易发生不可逆变形,使用寿命更长。
更详细举例地,如图5、图7及图15所示,装配槽3206延伸方向的一端形成有止挡筋3207,另一端形成安装区域3208。
调压阀100的第一转动件120上限定有驱动块124,驱动块124与调压阀的第一转动件120的中心线之间具有间距。第二弹性件301的一端与装配槽3206的一端部的止挡筋3207抵靠,安装区域3208供驱动块124伸入,第二弹性件301的另一端与第一转动件120的驱动块124抵靠,第一转动件120相对于盖体装置30可转动,第一转动件120转动时使驱动块124压缩第二弹性件301,第二弹性件301的恢复力使第一转动件120转动复位,从而使调压阀100复位。
实施例二
本实施例提供了一种盖体,包括:调压阀装置10、开合盖联动机构20和盖体装置30。
如图2所示,调压阀装置10包括调压阀100、联动件200和复位驱动 件。
其中,复位驱动件包括第二弹性件301,第二弹性件301与盖体装置30及调压阀100抵靠。具有结构简单,成本低,复位驱动及时性好、响应精度高等优点。
进一步地,如图4、图5和图7所示,第二弹性件301呈弧形,并沿调压阀100的周向延伸设置。这样,第二弹性件301的弹力大致沿调压阀100的切向,对于驱动调压阀100转动以促进调压阀100复位而言,可具有更高的驱动能效和更大的驱动行程,这样,可以更可靠地保证对调压阀100驱动到位,从而更好地保障调压阀100自动复位至初始挡位的到位效果。且相对来讲,通过设置第二弹性件301呈弧形并沿调压阀100的周向延伸,这样,调压阀100对第二弹性件301的反作用大致沿第二弹性件301的切向,第二弹性件301的受力效果和变形效果更好,从而延长第二弹性件301的寿命。
进一步地,如图10所示,调压阀100限定有驱动块124,驱动块124与调压阀100的中心线之间具有间距,第二弹性件301的一端与盖体装置30抵靠,另一端与驱动块124抵靠。这样,第二弹性件301的弹力可以良好地驱动调压阀100转动,驱动具有高效性。
进一步举例地,如图7所示,第二弹性件301的一端与盖体装置30抵靠,盖体装置30上在第二弹性件301的另一端的位置处形成有安装区域3208(大致可参照附图7中所示的虚线框区域进行理解),该安装区域3208供驱动块124布置,当调压阀100装配到盖体装置30上,驱动块124相应位于安装区域3208并与第二弹性件301的另一端配合,这样,调压阀100动作,使得驱动块124压缩第二弹性件301;或驱动块124被第二弹性件301的弹力驱动,使得调压阀100复位至初始位置。
进一步地,如图7和图5所示,盖体装置30具有面盖32,面盖32上设有装配槽3206,第二弹性件301容置于装配槽3206内并沿装配槽3206伸缩。一方面,装配槽3206的设置更方便第二弹性件301的安装和定位,另一方面,装配槽3206的导向作用可以良好地引导第二弹性件301的变形方向,这样,第二弹性件301的变形效果更好,不容易发生不可逆变形, 使用寿命更长。
更详细举例地,如图5和图7所示,面盖32上设有大致呈弧形的装配槽3206,第二弹性件301为伸缩弹簧且大致沿弧形的装配槽3206延伸设置,并沿装配槽3206进行伸缩变形。其中,装配槽3206延伸方向的一端形成有止挡筋3207,另一端形成安装区域3208,第二弹性件301的一端与止挡筋3207抵靠,另一端与位于安装区域3208位置的驱动块124抵靠。
在某些具体实施例中,开合盖联动机构20包括自锁滑块21,自锁滑块21设置在盖体装置30上,且盖体装置30开盖联动自锁滑块21运动,并通过自锁滑块21联动调压阀装置10的联动件200,使联动件200解除对调压阀装置10的调压阀100的挡位锁定。该结构满足开盖触发调压阀装置10自动复位的同时,具有结构简单,成本低的优点,简言之,可以利用盖体原本具有的自锁滑块21来对调压阀装置10进行开盖触发控制,改造成本低,且部件之间的相适性好,改造简单、方便。
更详细地,如图3所示,盖体装置30包括盖本体31,盖本体31设有锁扣结构3204。更详细举例地,盖本体31可包括面盖32和位于面盖32的内侧的锅盖33,锁扣结构3204可具体形成在锅盖33上并自锅盖33的内侧凸伸。或者,盖本体31可包括面盖32和位于面盖32的内侧的锁扣部件,锁扣结构3204具体形成在锁扣部件上。可以理解,锁扣结构3204用于与烹饪锅80的锅牙91扣合以锁紧锅盖33与烹饪锅80,从而使盖本体31盖合,且锁扣结构3204与锅牙91之间可以解除扣合以使盖本体31开盖。
如图8所示,自锁滑块21设有推杆24(推杆也可称之为自锁销)和第三弹性件25,第三弹性件25套装在推杆24的外侧。锅盖33上设有通孔,推杆24的一部分沿通孔伸至锅盖33的内侧。
其中,盖本体31开盖的过程中,锅牙91会向外顶起推杆24,使推杆24向外运动并压缩第三弹性件25。其中,由于推杆24设置在自锁滑块21上,推杆24向外运动的过程中会联动自锁滑块21向外运动。从而实现了盖本体31开盖对自锁滑动的联动作用。
另外,本领域技术人员可以理解,自锁滑块21具有使盖本体31自锁 的功能。具体地,如图8所示,自锁滑块21上设有浮子孔23,如图3所示,盖本体31上限定有浮子70,当浮子70浮起,浮子70穿过浮子孔23,这样,浮子70限制自锁滑块21向外运动,相应地,利用推杆24可反过来限制锅牙91运动,从而限制锅牙91与锁扣结构3204解除扣合,实现盖本体31自锁。相应地,该情况下,自锁滑块21也不会通过联动件200使调压阀100自动向初始位置复位。
在某些具体实施例中,如图8所示,自锁滑块21上设有止挡部22,如图9所示,联动件200上限定有适配止挡部22的止挡结构230;当盖体装置30开盖,止挡部22作用于止挡结构230并驱动联动件200运动,使联动件200解除对调压阀100的挡位锁定。止挡部22的限定具有结构简单,易于实施的优点,可以方便、简单地对现有自锁滑块21改造获得,改造成本低,适于在领域内推广。
举例地,如图8所示,止挡部22可以具体为自锁滑块21上设置的卡钩,该卡钩与自锁滑块21之间可以为一体式结构,也可以为分体式结构。进一步地,止挡部22可以具体设置在自锁滑块21远离推杆24的一端。
举例地,如图9所示,止挡结构230可以具体为联动件200上的凸块,该凸块可以与联动件200一体,当然,也可以与联动件200分体。进一步地,止挡结构230可以具体设置在联动件200的凸弧面220与导向杆240之间。
进一步地,本实施例的盖体还包括:操作控制组件40,操作控制组件40配置为驱动调压阀装置10的活动阀体140打开。这样,用户可通过操作控制组件40手动操作控制调压阀装置10的活动阀体140打开进行排气,产品使用更具灵活性和安装性。
举例而言,如图3所示,操作控制组件40包括操作部41(可以更具体为按钮)和传动杠杆42。
如图6所示,盖体装置30包括面盖32,面盖32的内表面设有安装座3209,传动杠杆42铰接于安装座3209,使得传动杠杆42连接于面盖32并相对于面盖32可转动。
其中,如图3所示,传动杠杆42以铰接位置为支点,并自支点向两侧 分别延伸以分别形成传动臂。其中一条传动臂延伸至操作部41的下方,另一条传动臂延伸至活动阀体140的下方,当操作部41向下按压其下方的传动臂,活动阀体140下方的传动臂将活动阀体140向上顶起,这样,活动阀体140向上运动使得封堵部142打开阀芯110的排气通道,实现控制活动阀体140打开进行排气。且传动杠杆42通过力臂设计可以实现对操作部41操作更加省力,也可以使得操作控制组件40的布局更加灵活方便。
更进一步地,盖体装置30还包括密封件60,如图6所示,面盖32的安装槽3201底部设有密封装配槽3214。如图3所示,密封件60安装于密封装配槽3214,传动杠杆42的传动臂穿设于密封件60,并伸入安装槽3201内以对安装槽3201内的活动阀体140驱动。
更进一步地,盖体还包括:降噪盖50,降噪盖50用于盖在调压阀100的外侧,对经调压阀100排放的气流降噪。
实施例三
本实施例提供了一种盖体,包括:调压阀装置10、开合盖联动机构20和盖体装置30。
其中,如图21所示,调压阀装置10包括调压阀100和复位驱动件(具体可参照第二弹性件301进行理解)。
调压阀100具有多个挡位,且多个挡位中的一者为所述初始挡位。调压阀100用于调挡和限压,具体用于将烹饪腔内的压力限制在当前挡位所配套的限压压力以下。
其中,如图21所示,开合盖联动机构20包括联动件200,联动件200适于锁定调压阀100的挡位,联动件200设有自锁销250,自锁销250配置为与锅牙91配合使开盖时通过锅牙91联动联动件200运动,使联动件200解除对调压阀100的挡位锁定;当联动件200解除对调压阀100的挡位锁定,复位驱动件驱动调压阀100至初始挡位。
更详细地,联动件200为自锁滑块。利用自锁滑块适配调压阀100以对调压阀100锁定或解锁,满足开盖触发调压阀100进行自动归位调节的使用需求的同时,具有结构简单,成本低的优点,简言之,可以利用盖体原本具有的自锁滑块来对调压阀100进行开盖触发控制,改造成本低,且 部件之间的相适性好,改造简单、方便。
进一步举例地,自锁滑块限定有配合部260,配合部260适于与调压阀100配合以对调压阀100锁定。
更具体地,如图23所示,配合部260具体为设置在自锁滑块一端部的凸起,凸起朝调压阀100延伸。其中,调压阀100上设有配合槽,凸起用于伸入配合槽内,利用凸起与配合槽102抵靠限制调压阀100运动,从而锁定调压阀100。
在某些具体实施例中,凸起与自锁滑块可为一体式结构。更方便产品的加工和生产,且也利于简化产品的装配步骤。
在某些具体实施例中,凸起具有凸弧形过渡圆角。这样,凸起的凸弧形过渡圆角的设置使得联动件200上构造形成凸弧面220,并以凸弧面220与配合槽102配合以锁定调压阀100,可以减少自锁滑块与调压阀100之间的摩擦损伤。
进一步地,调压阀装置10还包括第一弹性件400,第一弹性件400与联动件200配合。联动件200设置在盖体装置30上并相对于盖体装置30可活动。当联动件200运动以解除对调压阀100的挡位锁定,联动件200使第一弹性件400变形;当第一弹性件400弹性恢复,第一弹性件400的弹力驱动联动件200使联动件200朝调压阀100运动。
更详细地,第一弹性件400为锁销弹簧,其中,自锁滑块的一端设有凸起,自锁滑块远离凸起的一端设有自锁销250,锁销弹簧套装在自锁销250的外侧,锁销弹簧与自锁滑块以及盖本体抵靠。自锁销250配置为与锅牙91配合使开盖时通过锅牙91联动自锁滑块运动,锁销弹簧与自锁滑块配合并用于驱动自锁滑块复位。自锁滑块设置在盖体装置30上,且自锁滑块及自锁销250沿X方向可运动。
更详细地,如图25和图26所示,示意了盖体在合盖状态的部分结构。如图27和图28所示,示意了烹饪设备在合盖状态的部分结构。
参照图27和图28可见,当烹饪设备在合盖状态,自锁销250与锅牙91错位,这时,自锁销250未被锅牙91沿X方向向外顶起,自锁滑块因锁销弹簧的弹力位于自锁滑块在X方向上的活动范围内相对靠内的位置。
同样处于合盖状态,参照图25和图26,由于自锁滑块在X方向上的活动范围内相对靠内的位置,自锁滑块的配合部260伸入调压阀100的配合槽内,限制调压阀100,具体例如限制调压阀100沿S方向转动,从而使调压阀100锁定。
如图29和图30所示,示意了盖体在开盖状态的部分结构。如图31和图32所示,示意了烹饪设备在开盖状态的部分结构。
参照图31和图32可见,当烹饪设备在开盖状态,自锁销250与锅牙91位置对应,这时,自锁销250被锅牙91沿X方向向外顶起,从而使自锁滑块在X方向上的活动范围内相对靠外的位置。
同样处于合盖状态,参照图29和图30,由于自锁滑块在X方向上的活动范围内相对靠外的位置,自锁滑块的配合部260脱出调压阀100的配合槽,解除自锁滑块对调压阀100的限位,具体例如使得调压阀100可以沿S方向转动,从而使调压阀100解锁。
经由上述可见,实现了盖体装置30开盖同时,自锁滑块解除对调压阀100的限位,也即解除对调压阀100的锁定,这时,复位驱动件驱动调压阀100向初始挡位复位。盖体装置30合盖时,由于自锁销250未被顶起,在锁销弹簧的弹力作用下,自锁滑块可与调压阀100配合对调压阀100锁定,当然,可以理解的是,该合盖状态下,自锁滑块也可以运动压缩锁销弹簧并实现对调压阀100解锁。
更进一步地,复位驱动件包括扭簧,扭簧与盖体装置30及调压阀100抵靠。
更具体而言,扭簧一端抵靠盖体装置30,另一端抵靠调压阀100的第一转动件。当第一转动件转动进行调压,使得扭簧弹性变形。扭簧弹性恢复驱动第一转动件,使第一转动件联动阀体组件(具体参照第二转动件、活动阀体进行理解)进行复位。
进一步地,如图22所示,盖体装置30具有面盖32,面盖32上设有安装槽3201,第一转动件120至少部分位于安装槽3201内,安装槽3201的侧壁设有第一旋转卡接部3217,第一转动件120设有第二旋转卡接部125,第一旋转卡接部3217与第二旋转卡接部125之间旋转卡接,以限制 第一转动件120脱离安装槽。
更进一步地,如图22所示,扭簧装配在安装槽3201的底壁与第一转动件120的底部之间。
可以理解的是,参照图21至图32,本实施例2与上述实施例1的相同之处(如调压阀的第一转动件、第二转动件、活动阀体等结构、调压阀的配合槽与联动件的配合结构及联动过程等),在不冲突的前提下,可以参照上述实施例1的内容进行理解,在此不再重复。
当然,本设计的调压阀100并不局限于本实施例中采用调节阀体组件配重来调节限压压力的举例说明,在其他实施例中,也可采用螺旋结构(如螺纹)+控压弹簧的结构形式,调压阀100通过螺旋结构(如螺纹)调整控压弹簧的预紧力达到控压的目的。
本申请第二方面的实施例提供了一种烹饪设备,包括:烹饪锅80;如本申请第一方面的任一实施例中所述的盖体,盖体与烹饪锅80盖合并围成烹饪腔,盖体的调压阀装置10与烹饪腔连通。
更详细地,调压阀装置10的阀芯110的排气通道与烹饪腔连通,且调压阀装置10的调压阀100控制阀芯110开闭并对烹饪腔控压。
本申请上述实施例提供的烹饪设备,通过设置如本申请第一方面的任一实施例中所述的盖体,从而具有上述全部有益效果,在此不再赘述。
举例地,烹饪设备包括电饭煲、压力锅、电蒸锅、蒸汽煲中的一种或多种的组合。

其有益效果是:可以实现烹饪过程的多级调压功能,满足对不同食材的烹饪需求;且开盖时能实现双段阀自动复位,避免用户使用调压功能挡时忘记回位。
实施例四
如图36所示,本申请第三方面的实施例提供了一种盖体组件,包括:盖本体31’、阀组件100’和弹性复位件301’。
具体地,阀组件100’装配在盖本体31’上,阀组件100’的至少一部分相对于盖本体31’可活动;弹性复位件301’分别连接盖本体31’和阀组件100’,当阀组件100’运动,阀组件100’驱动弹性复位件301’变形,当弹性复位件301’在自身恢复力的作用下复位,弹性复位件301’驱动阀组件100’的可活动部分复位。
本申请上述实施例提供的盖体组件,设有弹性复位件301’,并使阀组件100’运动时联动弹性复位件301’使弹性复位件301’变形蓄能,当弹性复位件301’弹性恢复,使弹性复位件301’的弹性恢复力驱动阀组件100’复位,阀组件100’的复位效果好,可以更好地避免阀组件100’复位不当引起的下一次烹饪挡位不对带来的不良影响,如处于排气挡位发生水烧干等风险和危害,提升产品的安全性。且本结构中,采用弹性复位件301’进行复位驱动,成本低,同时,弹性复位件301’满足复位驱动目的的同时,结构更简单,也更利于节省空间,从而实现盖体组件节省体积。
举例而言,盖体组件用于具有烹饪腔的烹饪设备,例如,用于电饭煲、电压力锅、微压饭煲、蒸汽煲等。更具体地,烹饪设备除具有盖体组件外,还具有烹饪锅,盖体组件与烹饪锅盖合围成烹饪腔。阀组件100’配置为对烹饪腔限压。例如,阀组件100’具体为调压阀,调压阀适于将烹饪腔内的压力限制在调压阀所调节到的限压压力以下,其中,通过调压阀相对于盖本体31’运动,实现调压阀的限压压力调节过程。
进一步地,如图34、图36和图37所示,盖本体31’设有装配槽3206’,弹性复位件301’容置于装配槽3206’内。可以实现弹性复位件301’良好地导向以及装配过程中的快速定位和安装。
其中,装配槽3206’限定有第一配合部,弹性复位件301’与第一配合部配合;阀组件100’相对盖本体31’可转动,阀组件100’上设有第二配合部,第二配合部伸入装配槽3206’内并与弹性复位件301’配合,当阀组件100’转动,第二配合部联动弹性复位件301’使弹性复位件301’变形。这样,阀组件100’运动时,可经由第二配合部向弹性复位件301’施力使变形实现蓄能,当弹性复位件301’弹性恢复时,弹力可联动阀组件100’进行复位,从而实现良好的复位驱动功能,使阀组件100’复位效果更好。
且本结构满足弹性复位件301’对阀组件100’复位驱动功能的同时,弹性复位件301’的安装位置和活动范围集成性好,更利于节省空间,且具有结构简单,加工性好、装配简便的优点,且可实现弹性复位件301’在盖本体31’上快速定位和安装,提升产品的装配效率、降低产品的成本,且利用装配槽3206’也可实现对弹性复位件301’更好的限位和导向,弹性复位件301’的装配更稳定,弹性变形效果更好,这样,产品的弹性复位功能更可靠,产品使用寿命也更长。
举例而言,弹性复位件301’可具体包括弹簧。具体如,弹簧的一端与第一配合部抵靠,另一端与第二配合部抵靠。这样,阀组件100’运动使得第一配合部与第二配合部之间靠近时,压缩弹簧进行蓄能。弹簧释放弹性势能时,弹簧伸长而弹性恢复,这时,弹力驱动第一配合部与第二配合部之间远离,这样,通过第二配合部相对于第一配合部运动使得阀组件100’同时在弹力的驱动作用下复位,实现复位驱动功能。
当然,本方案并不局限于此,在另一些实施例中,也可设计弹簧的一端与第一配合部连接,另一端与第二配合部连接。当阀组件100’运动使得第一配合部与第二配合部之间远离,拉伸弹簧进行蓄能。弹簧释放弹性势能时,弹簧缩短而弹性恢复,这时,弹力驱动第一配合部与第二配合部之间靠近,这样,通过第二配合部相对于第一配合部运动使得阀组件100’同时在弹力的驱动作用下复位,实现复位驱动功能。
且可以理解,无论是拉伸弹簧还是压缩弹簧,本结构中,通过装配槽3206’容纳弹簧,并使弹簧在装配槽3206’内实现伸缩,具体例如,盖本体31’具有面盖32’,当然,可以理解,盖本体31’除了包括面盖32’以外,根 据需求盖本体31’还可进一步包括内盖、锅盖(或盖板)等。其中,面盖32’上凹陷形成有装配槽3206’,弹簧安装于面盖32’上的装配槽3206’内。这样,实现驱动目的的同时,一方面,可利于弹簧在盖本体31’上横卧布置,更节省产品的空间体积,另一方面,对弹簧的限位、导向作用更好,弹簧受力效果可更好,同时,也具有组装方便的优点。且弹簧可以提供更大的伸缩变形量,从而提供更大的复位驱动行程和更大的弹力,这样,复位驱动功能更加可靠,复位驱动也更平稳。
当然,弹性复位件301’并不局限于弹簧,在其他实施例中,也可设计弹性复位件301’为弹性橡胶、弹性硅胶、弹片等。
在某些实施例中,进一步地,如图37和图38所示,第一配合部包括止挡筋3207’,止挡筋3207’位于装配槽3206’内并与弹性复位件301’抵靠。这样,盖本体31’的加工性更好,利于降低产品的成本,且具有组装便利性,如装配槽3206’容纳弹性复位件301’后,使止挡件与弹性复位件301’抵靠即可,装配简单高效。
进一步举例地,如图37所示,止挡筋3207’更具体为形成在装配槽3206’延伸方向的一端的止挡壁,弹簧的一端抵靠在止挡壁上。
在某些实施例中,更详细举例地,如图42所示,第二配合部包括驱动块124’,驱动块124’与阀组件100’的中心线之间具有间距(可以理解,中心线是为方便理解本方案所拟定的参照基准,并非实体特征,阀组件100’的中心线可以理解为阀组件100’的中心轴线,也可以理解为阀组件100’转动时的轴线)。
更详细例如,如图42所示,阀组件100’具有调压拨动件120’,调压拨动件120’具有环形体部位,驱动块124’设置在环形体上并自环形体沿环形体的轴向向下凸起,这样,驱动块124’与环形体的中心线之间形成偏心位置关系,使得阀组件100’绕其中心线转动时,驱动块124’相应做弧线运动。
如图47所示,驱动块124’自阀组件100’向装配槽3206’延伸并伸入装配槽3206’内,且驱动块124’与弹性复位件301’抵靠。这样,驱动块124’做圆周运动与阀组件100’转动形成响应关系,使得弹性复位件301’的弹力可以良好地驱动阀组件100’转动使阀组件100’更可靠地复位,且驱动具有 高效性。
此外,根据需求可进一步设计使驱动块124’与装配槽3206’之间形成导向配合,具体例如,装配槽3206’至少部分设置为与驱动块124’大致适配的安装区域3208’(安装区域3208’可具体参照附图39中示意的虚线框位置进行理解),驱动块124’具体伸入安装区域3208’,并与安装区域3208’滑动导向配合。这样,驱动块124’沿装配槽3206’滑动形成导向作用,即提升了阀组件100’的运动平稳性,且也使得弹性复位件301’的受力效果可更好。
进一步地,如图39所示,盖本体31’设有安装槽3201’,阀组件100’装配在安装槽3201’上,这样,可以实现对阀组件100’良好地限位,阀组件100’的运动更平稳有保障,这可相应使得弹性复位件301’与阀组件100’的配合更加平稳,从而保证更高效精度的复位驱动功能。
更进一步地,如图39所示,装配槽3206’位于安装槽3201’内并沿安装槽3201’的周向延伸。这样,阀组件100’与安装槽3201’和装配槽3206’可以一次装配定位,组装方便,操作简单,且装配槽3206’位于安装槽3201’内,更加节省了对盖本体31’的占用空间量,更利于精简产品体积。
进一步地,如图35所示,阀组件100’的一部分位于安装槽3201’内,阀组件100’设有搭靠边125’,搭靠边125’搭靠在安装槽3201’周围的部位上。这样,可以使得对阀组件100’的支撑更均匀,从而更好地维持阀组件100’与装配槽3206’及弹性复位件301’的配合精度,并减小阀组件100’与装配槽3206’之间的干涉或摩擦,提升阀组件100’运动顺畅性。
更进一步地,如图37所示,装配槽3206’包括弧形槽,弹性复位件301’至少部分容置于弧形槽内并沿弧形槽延伸;阀组件100’相对于盖本体31’运动驱动第二配合部做弧线运动,使第二配合部驱动弹性复位件301’,以使弹性复位件301’在第二配合部的驱动下沿弧形槽变形。这样,阀组件100’对弹性复位件301’的作用力大致沿弹性复位件301’的切向,且弹性复位件301’大致沿弧形槽进行弧线伸缩,弹性复位件301’的受力与变形之间契合性更好,弹性复位件301’的受力效果和在弧形槽导向作用下的变形效果更好,弹性复位件301’不容易损坏,从而延长弹性复位件301’的寿命。且相对来讲,弹性复位件301’的弹力大致沿阀组件100’的切向,对于驱动阀组 件100’转动复位而言,可具有更高的驱动能效和更大的驱动行程,这样,可以更可靠地保证对阀组件100’驱动到位,从而更好地保障阀组件100’自动复位的到位效果,且弹性复位件301’不容易卡滞,也不会出现死点,弹性复位功能更加可靠。
且弧形槽的设置,在相同的弹性变形行程调节下,可更加节省产品的尺寸需求,从而可以促进减小产品体积的目的。
更详细地,如图37所示,弧形槽沿长度方向的一端设有止挡筋3207’,另一端内形成有安装区域3208’且安装区域3208’容置有驱动块124’。弹性复位件301’位于弧形槽内并沿弧形槽大致延伸呈弧形,并位于止挡筋3207’与驱动块124’之间。驱动块124’沿弧形槽做弧线运动以压缩弹性复位件301’,弹性复位件301’的弹性恢复力驱动驱动块124’,使驱动块124’沿弧形槽做弧线运动,以相应实现驱动阀组件100’复位。
进一步地,如图35和图47所示,装配槽3206’具有开口;阀组件100’具有封挡部126’,封挡部126’遮挡至少部分开口,驱动块124’设置在封挡部126’上且朝装配槽3206’延伸。这样,可以利用封挡部126’限制弹性复位件301’沿开口脱离装配槽3206’,实现弹性复位件301’更加稳定、可靠的限位和装配。且利用阀组件100’的封挡部126’对开口封挡,这样,装配阀组件100’和封挡开口通过一次装配实现,更加简化了产品的装配结构和步骤,减少了产品的零部件,且降低错装、漏装风险。
更进一步地,如图34、图39和图42所示,盖本体31’和阀组件100’中的一者设有旋转导槽123’,另一者上设有旋转限位凸块3202’,旋转限位凸块3202’伸入旋转导槽123’内并沿旋转导槽123’滑动,且旋转限位凸块3202’与旋转导槽123’的侧壁配合限制封挡部126’打开开口,以及限制第二配合部离开装配槽3206’。其中,利用旋转限位凸块3202’与旋转导槽123’配合来对阀组件100’相对于盖本体31’的运动进行导向和限位,这样,阀组件100’的运动更加平稳可靠,产品的控制精度可更高。通过旋转限位凸块3202’与旋转导槽123’配合限制封挡部126’打开开口,并限制第二配合部离开装配槽3206’,这样,对弹性复位件301’的限位、导向效果更好,更进一步提升复位驱动精准性,并且更好地保障弹性复位件301’与阀组件100’的 装配可靠,这样,对阀组件100’的弹性复位驱动功能也更加可靠。
进一步地,阀组件100’上设有拨钮122’。更方便用户通过拨钮122’驱动阀组件100’运动,操作更具有方便性。
在某些实施例中,如图34和图35所示,盖本体31’上限定有排气通道111’,更具体例如,盖本体31’上设有阀芯110’,阀芯110’内形成排气通道111’。
其中,如图35所示,阀组件100’包括:调压拨动件120’、内阀体140’和外阀体130’。调压拨动件120’设于盖本体31’上且相对于盖本体31’可转动;内阀体140’适于与排气通道111’配合进行限压;如图46所示,外阀体130’与内阀体140’活动连接,其中,外阀体130’与调压拨动件120’相连;当调压拨动件120’转动,调压拨动件120’联动外阀体130’,使外阀体130’相对于排气通道111’上升或下降,以改变内阀体140’配合到排气通道111’上的重量。
其中,当转动调压拨动件120’,调压拨动件120’会带动外阀体130’随之转动,其中,外阀体130’转动过程中会进行上下运动,这样,通过外阀体130’上下运动调节外阀体130’对内阀体140’的配重,使内阀体140’配合在排气通道111’上的重量改变,实现调节对排气通道111’的限压压力。如,通过外阀体130’上下运动进行上下位置调整,其中,根据外阀体130’的上下位置变化,在一些工况下,根据具体需求可实现使外阀体130’的至少部分重力施加于内阀体140’并对内阀体140’配重,以使外阀体130’的至少部分重力与内阀体140’的重力之和用于重力限压;在另一些工况下,根据具体需求也可实现使外阀体130’的重力不施加于内阀体140’,而利用内阀体140’的至少部分重力用于重力限压;在另一些工况下,根据具体需求也可使外阀体130’和内阀体140’的重力均不用于重力限压,使阀组件100’维持打开。如此,通过使外阀体130’转动,从而形成相应的限压压力调节响应,更好地满足用户的不同烹饪压力需求。
且通过本结构,实现外阀体130’转动形成上下运动进行限压压力调节的目的的同时,内阀体140’的限压过程基本不受影响,限压过程更加精确可靠,且通过外阀体130’以进行上下运动联动,实现配重调节,整个结构 简单化,且也方便外阀体130’和内阀体140’整体拆出清洗,日常使用更加方便。
更详细举例而言,如图48所示,盖本体31’上设有调压凸块3216’。如在盖本体31’的面盖32’上设置调压凸块3216’。
如图43所示,外阀体130’上设有调压面530’,调压凸块3216’与调压面530抵靠,且外阀体130’转动使调压面530与调压凸块3216’的抵靠位置改变,从而调节外阀体130’的升降高度。
更具体地,如图43所示,调压面530’包括第一级调压平面531’、第二级调压平面532’、第三级调压平面533’、第一调压斜坡534’和第二调压斜坡535’,第一调压斜坡534’过渡在第一级调压平面531’与第二级调压平面532’之间,且第一调压斜坡534’自第一级调压平面531’向第二级调压平面532’位置升高,第二调压斜坡535’自第二级调压平面532’向第三级调压平面533’位置升高。
当调压凸块3216’抵靠于第三级调压平面533’上,调压拨动件120’处于初始位置,且阀组件100’的外阀体130’位置最低,烹饪腔内进行高压烹饪;当调压凸块3216’抵靠于第二级调压平面532’上,烹饪腔内进行低压烹饪;当调压凸块3216’抵靠于第一级调压平面531’上,阀组件100’的外阀体130’的位置最高,烹饪腔内进行无压烹饪。
通过本方案,且通过本结构,实现外阀体130’转动形成上下运动进行限压压力调节的目的的同时,内阀体140’的限压过程基本不受影响,限压过程更加精确可靠,且通过阀组件100’转动以进行上下运动联动,实现阀组件100’配重调节,整个结构简单化,且也方便阀组件100’整体拆出清洗,日常使用更加方便。
当然,本设计也并不局限于上述的调压拨动件120’与外阀体130’之间分体且两者装配连接的结构,在其他实施例中,也可设计调压拨动件120’为外阀体130’或外阀体130’的一部分,例如,调压拨动件120’与外阀体130’连接成一体或两者之间一体成型,使外阀体130’的一部分作为调压拨动件120’。这样,实现外阀体130’转动形成上下运动进行限压压力调节的目的的同时,更加精简产品的零部件数量,降低产品的成本,也更方便产品的 日常装卸清洗。
当然,本设计也并不局限于上述的通过调压面530’和调压凸块3216’实现当外阀体130’转动引导外阀体130’上下运动的结构,根据需求,也可设计外阀体130’可利用螺纹结构实现当外阀体130’转动引导外阀体130’上下运动。
在某些进一步的实施例中,如图42和图43所示,调压拨动件120’和外阀体130’中的一者上设有导向筋134’,另一者设有凹槽121’,导向筋134伸入凹槽121’内并与凹槽121’啮合使外阀体130’随调压拨动件120’转动,且导向筋134’沿凹槽121’可滑动,使调压拨动件120’与外阀体130’之间可上下活动。既实现了调压拨动件120’带动外阀体130’转动的传动连接,也使得外阀体130’相对于调压拨动件120’可上下滑动,以供外阀体130’通过上下运动进行位置调节,利用导向筋134沿凹槽121’滑动形成导向作用,这样,外阀体130’的上下运动方向更准确,压力控制更加准确可靠,且导向筋134’与凹槽121’配合,还具有结构简单、调压拨动件120’与外阀体130’之间装卸更方便的优点,可方便用户将外阀体130’及内阀体140’从调压拨动件120’上取下进行清洗。
进一步地,如图48所示,弹性复位件301’与调压拨动件120’配合,当调压拨动件120’转动,调压拨动件120’联动弹性复位件301’使弹性复位件301’变形,当弹性复位件301’在自身弹性恢复力作用下复位,弹性复位件301’驱动调压拨动件120’转动进行复位。如此设计可使得施加于外阀体130’的力的大小、方向的可控性更好,这样外阀体130’和内阀体140’对烹饪腔的限压可靠性和精准性更易于保障,提升产品的压控精度。且对外阀体130’和内阀体140’拆出进行清洗时,不会影响到调压拨动件120’与盖本体31’及弹性复位件301’之间配合,从而进一步提升了产品的装卸便利性。
更具体地,如图42所示,调压拨动件120’具有环形体,环形体周向的某一位置处向下凸伸设置有驱动块124’,驱动块124’与弹性复位件301’配合。另外,如图42所示,环形体上设有拨钮122’,以方便用户驱动拨钮122’使调压拨动件120’转动。更进一步地,外阀体130’嵌套装配在环形体内,且环形体的内侧面101’设有凹槽121’或导向筋134’,外阀体130’的侧 壁的外表面上设有导向筋134’或凹槽121’。环形体的至少部分下表面形成封挡部126’并且封挡装配槽3206’的至少部分开口。
具体实施例二
本具体实施例提供了一种盖体组件,包括盖本体31’、弹性复位件301’、阀组件100’。
阀组件100’的至少一部分相对于盖本体31’可转动。具体如,阀组件100’包括调压拨动件120’、外阀体130’、内阀体140’,调压拨动件120’设于盖本体31’并可转动。外阀体130’与调压拨动件120’相连并随调压拨动件120’转动。内阀体140’与外阀体130’活动连接。具体如,外阀体130’嵌套装配在内阀体140’的外侧,外阀体130’的侧壁的内壁面上设有限位凸起1351’和柔性件1352’,限位凸起1351’和柔性件1352’分别相对于外阀体130’的内壁面凸起,且限位凸起1351’和柔性件1352’之间上下间隔地分布。内阀体140’的侧壁的外壁面上设有限位块141’,限位块141’位于限位凸起1351’与柔性件1352’之间,内阀体140’相对于外阀体130’可上下活动,且内阀体140’相对于外阀体130’上下运动使限位块141’往返于限位凸起1351’和柔性件1352’之间。其中,柔性件1352’的设置方便内阀体140’与外阀体130’之间卡接装配,这样,内阀体140’与外阀体130’之间装卸更加方便,更方便于产品的日常拆洗。
盖本体31’上限定有排气通道111’,内阀体140’上设有封堵部142’,封堵部142’适于与阀芯110’配合以密封或打开排气通道111’。
外阀体130’上设有调压面,盖本体31’的面盖32’上设有调压凸块3216’,调压凸块3216’与调压面抵靠,且调压面通过不同的位置与调压凸块3216’抵靠使得外阀体130’上升或下降,以改变外阀体130’对内阀体140’的配重,从而相应改变内阀体140’配合到排气通道111’上的重量,进一步实现改变限压压力的大小。
弹性复位件301’具体为弹簧,弹性复位件301’位于阀组件100’与盖本体31’的面盖32’之间,在盖本体31’的面盖32’上设置有弧形的装配槽3206’(也即弧形槽),弹性复位件301’位于装配槽3206’内并沿装配槽3206’相适地构造成弧形。装配槽3206’的一端设有止挡筋3207’,装配槽3206’的 另一端设有安装区域3208’,安装区域3208’用于配合阀组件100’上的驱动块124’。
装配槽3206’具有底壁和相对的两个侧壁。装配槽3206’的两个侧壁为嵌套的两个弧形壁,并实现弧形的弹性复位件301’的径向限位。阀组件100’的调压拨动件120’下表面(也即封挡部126’)与面盖32’的底面(也即装配槽3206’的底壁)形成弹性复位件301’的轴向限位。止挡筋3207’和驱动块124’形成弹性复位件301’的周向限位。确保弹性复位件301’的运动顺畅、不卡滞。
另外,参照图35,示意了盖体组件的剖视结构,盖本体31’设有排气阀芯110’,具体地,阀芯110’内限定有排气通道111’,多段阀(也即阀组件)套在阀芯110’上。盖体组件还包括操作控制组件40’,操作控制组件40’包括操作部41’(可以更具体为按钮)和手动排气杠杆(也即传动杠杆42’)。

阀组件100’与面盖32’之间安装有自动复位弹簧(也即弹性复位件301’),阀组件100’的一端与复位杆(也即联动件200’)连接,阀组件100’旋转的同时与推动多段阀向上运动,并压缩自动复位弹簧,使其具有一定的恢复力。阀组件100’上的调压凹坑结构(也即配合槽102’)与复位杆上的凸点(也即凸弧面220’)配合,实现挡位的设定。
当开盖时,自锁滑块21’的凸块(也即自锁滑块21’的止挡部22’)驱动复位杆的复位凸块(也即止挡结构230’),使复位杆上的凸点脱出阀组件100’上的调压凹坑,阀组件100’及多段阀在自动复位弹簧的作用下回复到初始位置,达到开盖自动复位的目的。
如图46所示,示意了多段阀的剖视结构,如图45所示,示意了多段阀的内阀体140’的结构,如图44所示,示意了多段阀的外阀体130’的结构。阀组件100’旋转的同时,调压外阀组件100’(也即外阀体130’)实现旋转、上下运动,使压在阀芯110’的排气口上的重量发生变化,即压在阀芯110’ 的排气口处的重量发生变化,从而达到烹饪设备的烹饪腔压力变化的目的。阀组件100’上设置有多个调压凹坑,分别对应不同的压力段,复位杆安装在面盖32’上,复位杆上设置复位杆弹簧(也即第一弹性件400’),复位杆的顶部(也即凸点或凸弧面220’)与阀组件100’的调压凹坑配合,在复位杆弹簧的预紧力作用下实现挡位的设定。

如图40所示,示意了自锁滑块21’的结构,自锁滑块21’上设置有滑块驱动凸块(也即止挡部22’)。
如图41所示,示意了复位杆(也即联动件200’)的结构,复位杆设置有凸点(也即凸弧面220’)、限位轴肩(也即第一限位结构210’)、复位杆凸块弹簧安装面(也即导向杆240)。
如图42所示,示意了阀组件100’的结构,阀组件100’上设置有凹槽121’、旋转导槽123’、调压凹坑(也即配合槽102’)、驱动块124’。
如图46所示,示意了双段阀的剖视结构,其中,多段阀由内阀组件(也即内阀体140’)、外阀组件(也即阀组件100’)、外阀硅胶卡件(也即柔性件1352’)组成,外阀硅胶卡件安装在外阀组件100’上,内阀组件100’在可在两者间上下活动;外阀硅胶卡件安装在外阀组件100’上,内阀组件100’卡接在外阀组件100’和外阀硅胶卡件之间,内阀组件100’有一定的上下活动空间。
更具体地,如图43所示,外阀体130’内形成贯穿的安装孔139’,安装孔139’的内壁上设有容置槽137’,容置槽137’内设有柔性件1352’,且柔性件1352’的一部分伸出容置槽137’并相对于安装孔139’的内壁凸起。外阀体130’上设有限位凸起1351’,限位凸起1351’与柔性件1352’间隔设置 形成第三限位结构135’,内阀体140’上设有限位块141’,限位块141’位于柔性件1352’与限位凸起1351’之间,限制内阀体140’脱离外阀体130’。且内阀体140’沿安装孔139’上下运动使限位块141’往返于柔性件1352’与限位凸起1351’之间。
进一步地,限位块141’包括凸扣,凸扣上限定有适于引导限位块141’与限位凸起1351’卡接装配的引导斜面1411’。柔性件1352’和引导斜面1411’的设置,方便外阀体130’与内阀体140’之间装卸。
如图45所示,示意了内阀组件100’(也即内阀体140’)的剖视结构,内阀组件100’上设有限位块141’。
如图43所示,示意了外阀组件100’的立体结构,如图44所示,示意了外阀组件100’的剖视结构。外阀组件100’上设有提手环136’、外阀硅胶卡件卡槽。外阀组件100’的壳体上设置滑动导向结构、导向筋134,滑动导向结构由第三级调压平面533’、第二级调压平面532’、排气(无压)平面(也即第一级调压平面531’)、第一调压斜坡534’、第二调压斜坡535’构成。
更详细地,导向筋134与阀组件100’配合实现转动功能,第一调压斜坡和/或第二调压斜坡与面盖32’上的调压凸块3216’(也即配合体)实现调节双段阀的配重从而达到调压的目的。阀组件100’旋转的同时,外阀体130’实现旋转并上升,外阀体130’上升后重量被面盖32’承受,没有压在阀芯110’上,故此时只有内阀体140’的重量压在阀芯110’的排气口处,故此时烹饪设备的烹饪腔内的压力较低就可以将内阀体140’推动而排气,实现低压烹饪;当外阀体130’在阀组件100’的带动下复位时,外阀组件100’下降,外阀体130’的限位凸起1351’压在内阀体140’的限位块141’上,此时从而内阀体140’和外阀体130’的重量都压在阀芯110’的排气口处,故此时烹饪设备的烹饪腔内的压力要达到较高才可以将内阀体140’推动而排气,实现高压烹饪,由此通过改变阀组件100’压在阀芯110’的排气口处的重量,从而实现调节烹饪设备内的烹饪腔压力变化的目的。
阀组件100’上设置有多个调压凹坑(也即配合槽102’),具体如调压拨动件120’上设有多个调压凹坑,多个调压凹坑分别对应不同的压力段, 复位杆安装在面盖32’上,复位杆上设置复位杆弹簧,复位杆的顶部与阀组件100’的调压凹坑配合,在复位杆弹簧的预紧力作用下实现挡位的设定。
复位杆上设置有复位凸块,与自锁滑块21’上的滑块驱动凸块配合,在面盖32’与阀组件100’之间设置有自动复位弹簧,旋转调压的过程中,自动复位弹簧提供恢复力,当开盖时,自锁滑块21’凸块驱动复位杆的复位凸块,使复位杆上的凸点脱出阀组件100’上的调压凹坑,阀组件100’在自动复位弹簧的作用下回复到初始位置,达到开盖自动复位的目的。
更详细举例而言,外阀体130’上限定有调压面530。调压面530包括第一级调压平面531’、第二级调压平面532’、第三级调压平面533’、第一调压斜坡534’和第二调压斜坡535’,第一调压斜坡534’过渡在第一级调压平面531’与第二级调压平面532’之间,且第一调压斜坡534’自第一级调压平面531’向第二级调压平面532’位置升高,第二调压斜坡535’自第二级调压平面532’向第三级调压平面533’位置升高。
另外,调压拨动件120’设有侧面101’,且侧面101’上限定有3个配合槽102’,分别为配合槽102a’、配合槽102b’、配合槽102c’。配合槽102a’对应高压挡位,配合槽102b’对应低压挡位,配合槽102c’对应无压挡位。
当调压凸块3216’抵靠于第三级调压平面533’上,如图49和图50所示,阀组件100’处于初始挡位(也即高压挡位),外阀体130’的位置最低,且联动件200’的凸弧面220’配合于对应高压挡位的配合槽102a’内以锁定调压拨动件120’,烹饪腔内进行高压烹饪;
当调压凸块3216’抵靠于第二级调压平面532’上,如图51所示,外阀体130’被抬高支撑在调压凸块3216’上使外阀体130’的重量经由盖体装置30’承担,阀组件100’处于低压挡位,且联动件200’的凸弧面220’配合于对应低压挡位的配合槽102b’内以锁定调压拨动件120’,烹饪腔内进行低压烹饪。
当调压凸块3216’抵靠于第一级调压平面531’上,如图52所示,外阀体130’继续被抬高并带动内阀体140’一起上升,使外阀体130’和内阀体140’的重量经由盖体装置30’承担,此时,内阀体140’离开阀芯110’,阀组件100’处于无压挡位或排气挡位,且联动件200’的凸弧面220’配合于对应 无压挡位的配合槽102c’内以锁定调压拨动件120’,外阀体130’的被调压凸块3216’顶至最高位置,烹饪腔内进行无压烹饪或排气档位。
由此实现通过改变阀组件100’压在阀芯110’上的重量从而实现调节烹饪设备内的烹饪腔压力的目的。
更进一步地,如图33所示,盖体组件还包括降噪盖50’,降噪盖50’用于盖在阀组件100’的外侧,对经阀组件100’排放的气流降噪。
其有益效果是:弹性复位件301’的安装简单、占用体积小,可制造性强。且弹性复位件301’的变形和运动顺畅、不卡滞。
且通过在面盖32’与阀组件100’之间设置有自动复位弹簧(也即弹性复位件301’),旋转以对阀组件100’进行调压的过程中,自动复位弹簧提供恢复力,当开盖时,自锁滑块21’凸块驱动复位杆的复位凸块,使复位杆上的凸点脱出阀组件100’上的调压凹坑,调压拨动件120’在自动复位弹簧的作用下联动外阀体130’回复到初始位置,达到开盖使阀组件100’自动复位的目的,避免用户使用调压功能挡时忘记回位。
本申请第四方面的实施例提供了一种烹饪设备,包括:烹饪锅和如本申请第三方面的任一实施例中所述的盖体组件,所述盖体组件与烹饪锅盖合形成烹饪腔。
本申请上述实施例提供的烹饪设备,通过设置如本申请第三方面的任一实施例中所述的盖体组件,从而具有以上全部有益效果,在此不再赘述。
具体实施例三
如图33至图52所示,本实施例提供了一种烹饪设备,包括烹饪锅和盖体组件。
如图33和图34所示,盖体组件包括:阀组件100’、联动件200’、自锁滑块21’、弹性复位件301’、盖体装置30’等。
阀组件100’具体为调压阀。阀组件100’具有调压拨动件120’、外阀体130’和内阀体140’等。
盖体装置30’包括盖本体31’、开合盖机构等,盖本体31’具有面盖32’,当然,还可具有侧盖、锅盖等。面盖32’上设有安装槽3201’,阀组件100’至少部分位于安装槽3201’内,外阀体130’套装在阀组件100’内,内阀体 140’套装在外阀体130’内。安装槽3201’的侧壁与阀组件100’之间设有一个或多个旋转限位凸块3202’以及一个或多个旋转导槽123’,旋转限位凸块3202’伸入旋转导槽123’内并沿旋转导槽123’滑动,且旋转限位凸块3202’与旋转导槽123’配合限制阀组件100’离开安装槽3201’。
更详细地,旋转导槽123’沿其所在的安装槽3201’侧壁的周向延伸,旋转导槽123’具有上侧壁和下侧壁,上侧壁与下侧壁之间间隔并围成供旋转限位凸块3202’滑动运动的空间。旋转限位凸块3202’位于上侧壁与下侧壁之间,利用上侧壁和下侧壁对旋转限位凸块3202’限位,限制阀组件100’脱离安装槽3201’。
安装槽3201’内设有一个或多个调压凸块3216’。调压凸块3216’为相对于安装槽3201’的内底面凸起的凸筋。外阀体130’上设有一个或多个调压面530,调压面530位于调压凸块3216’上且在数量上与调压凸块3216’形成一对一的配套关系。例如图39所示,安装槽3201’内设有3个调压凸块3216’,3个调压凸块3216’沿安装槽3201’的周向间隔地排列设置,外阀体130’设有3个调压面530来与3个调压凸块3216’适配,以使外阀体130’更加平稳。当然,调压凸块3216’的数量并不局限于3个,根据需求,还可具体为1个或2个、4个、5个甚至更多。
调压阀具有多个挡位,且多个挡位中的一者为初始挡位。例如,当配合体位于第二过渡面上,调压阀处于初始挡位。
调压阀用于调挡和限压,具体用于将烹饪腔内的压力限制在当前挡位所配套的限压压力以下。
联动件200’适于锁定调压阀的挡位。联动件200’与面盖32’之间设有第一弹性件400’。第一弹性件400’为弹簧,第一弹性件400’套装在联动件200’的导向杆240上并与联动件200’抵靠。
如图41所示,联动件200’远离第一弹性件400’的一端设有凸弧面220’。如图37所示,阀组件100’上设有侧面101’,侧面101’上设有多个配合槽102’,多个配合槽102’间隔地排列布置,并配套调压阀的多个挡位。侧面101’的一部分位于相邻配合槽102’之间并过渡衔接相邻配合槽102’,且相邻配合槽102’之间的侧面101’与配合槽102’的边缘呈弧形过渡103’。
联动件200’相对于盖体装置30’在第一位置与第二位置之间可运动,当联动件200’位于第一位置,凸弧面220’伸入配合槽102’内,以限制阀组件100’转动,从而将阀组件100’锁定在与该配合槽102’配套的挡位。
联动件200’上设有第一限位结构210’,盖体装置30’限定有第二限位结构3205’,当联动件200’运动至第二位置,凸弧面220’与配合槽102’解除配合,从而解除对调压阀的挡位锁定,且第一限位结构210’与第二限位结构3205’分开。
盖体装置30’限定有轨道槽3210’和复位引导槽3212’,联动件200’的一部分位于轨道槽3210’内,且联动件200’的运动经由轨道槽3210’导向和限位。联动件200’的一部分穿过复位引导槽3212’与调压阀配合以对调压阀锁定挡位,且复位引导槽3212’同时作为第二限位结构3205’,联动件200’的第一限位结构210’与复位引导槽3212’抵靠配合对联动件200’限位。
进一步地,开合盖机构包括自锁滑块21’、锁扣结构3204’等,自锁滑块21’设置在盖本体31’的内盖上,且当盖体装置30’开盖,盖体装置30’联动自锁滑块21’运动,并通过自锁滑块21’联动联动件200’,使联动件200’解除对调压阀的挡位锁定。
弹性复位件301’与调压阀配合,且当联动件200’解除对调压阀的挡位锁定,弹性复位件301’驱动调压阀至初始挡位。
弹性复位件301’包括弹性复位件301’。面盖32’上设有装配槽3206’。装配槽3206’大致呈弧形,弹性复位件301’为伸缩弹簧且大致沿弧形的装配槽3206’延伸设置,并沿装配槽3206’进行伸缩变形。装配槽3206’延伸方向的一端形成有止挡筋3207’,另一端形成安装区域3208’,弹性复位件301’的一端与止挡筋3207’抵靠,另一端与位于安装区域3208’位置的驱动块124’抵靠。
进一步地,如图35所示,锁扣结构3204’设置在盖本体31’上。更详细举例地,盖本体31’可包括面盖32’和位于面盖32’的内侧的锅盖,当然,盖本体31’还可包括侧盖等部件。锁扣结构3204’可具体形成在锅盖上并自锅盖的内侧凸伸。或者,盖本体31’可包括面盖32’和位于面盖32’的内侧的锁扣部件,锁扣结构3204’具体形成在锁扣部件上。可以理解,锁扣结构 3204’用于与烹饪锅的锅牙扣合以锁紧锅盖与烹饪锅,从而使盖本体31’盖合,且锁扣结构3204’与锅牙之间可以解除扣合以使盖本体31’开盖。
如图40所示,自锁滑块21’设有推杆24’(推杆也可称之为自锁销)和第三弹性件25’,第三弹性件25’套装在推杆24’的外侧。锅盖上设有通孔,推杆24’的一部分沿通孔伸至锅盖的内侧。
其中,盖本体31’开盖的过程中,锅牙会向外顶起推杆24’,使推杆24’向外运动并压缩第三弹性件25’。其中,由于推杆24’设置在自锁滑块21’上,推杆24’向外运动的过程中会联动自锁滑块21’向外运动。从而实现了盖本体31’开盖对自锁滑动的联动作用。
另外,本领域技术人员可以理解,自锁滑块21’具有使盖本体31’自锁的功能。具体地,如图40所示,自锁滑块21’上设有浮子孔23’,如图35所示,盖本体31’上限定有浮子70’,当浮子70’浮起,浮子70’穿过浮子孔23’,这样,浮子70’限制自锁滑块21’向外运动,相应地,利用推杆24’可反过来限制锅牙运动,从而限制锅牙与锁扣结构3204’解除扣合,实现盖本体31’自锁。相应地,该情况下,自锁滑块21’也不会通过联动件200’使调压阀自动向初始位置复位。
在某些具体实施例中,如图40所示,自锁滑块21’上设有止挡部22’,止挡部22’具体为卡钩或凸板,如图41所示,联动件200’上限定有适配止挡部22’的止挡结构230’。具体地,止挡结构230’具体为形成在联动件200’上的凸块,止挡部22’具体为卡钩或凸板,卡钩或凸板用于钩住凸块以牵引联动件200’运动使联动件200’对阀组件100’解锁。
具体地,当盖体装置30’开盖,止挡部22’作用于止挡结构230’并驱动联动件200’运动,使联动件200’解除对调压阀的挡位锁定。止挡部22’的限定具有结构简单,易于实施的优点,可以方便、简单地对现有自锁滑块21’改造获得,改造成本低,适于在领域内推广。
举例地,如图40所示,止挡部22’可以具体为自锁滑块21’上设置的凸筋,该凸筋与自锁滑块21’之间可以为一体式结构,也可以为分体式结构。进一步地,止挡部22’可以具体设置在自锁滑块21’远离推杆24’的一端。
举例地,如图41所示,止挡结构230’可以具体为联动件200’上的凸块, 该凸块可以与联动件200’一体,当然,也可以与联动件200’分体。进一步地,止挡结构230’可以具体设置在联动件200’的凸弧面220’与导向杆240之间。
阀组件100’为调压阀,且具体包括内阀体140’、外阀体130’及柔性件1352’。柔性件1352’安装在外阀体130’上,内阀体140’在可在柔性件1352’与内阀体140’这两者间上下活动;在外阀体130’上设置有导向筋134、调压斜坡,导向筋134与位于盖体组件上的阀组件100’配合实现转动功能,调压斜坡与盖体组件的面盖32’上的调压凸块3216’(也即配合体)实现阀组件100’的配重从而达到调压的目的,阀组件100’旋转的同时,使得外阀体130’实现旋转、上下运动,达到调节阀组件100’配合到阀芯110’上的重量目的。
烹饪锅可具体为内胆,烹饪设备为压力锅或饭煲,其中,压力锅或饭煲还可包括煲体(也可称之为锅体),烹饪锅位于煲体内,盖体组件盖合煲体的同时,对烹饪锅封盖。
当然,本设计并不局限于此,烹饪设备也可为蒸汽煲,对于蒸汽煲,可以省去上述的煲体。
当然,本设计并不局限于此,烹饪设备也可为锅具组件,对于锅具组件,烹饪锅可以为适于明火或电磁炉加热的锅体。
本实施例的有益效果是:弹性复位件301’的安装简单、占用体积小,可制造性强。且弹性复位件301’的变形和运动顺畅、不卡滞。阀组件100’具有多级调压功能,可以满足用户不同的烹饪限压压力需求。
采用外阀硅胶卡件,使得内阀组件与外阀组件之间形成柔性结构,便于产品的安装和拆卸清洗。
开盖时能实现阀组件100’自动复位,且复位精准,避免用户下一次使用调压功能挡时忘记回位或调压不准确的问题。
如图53至68所示,本申请第五方面的实施例提供了一种限压阀100”,包括:第一阀体130”和第二阀体140”。具体地,第一阀体130”设有第一限位部1321”;第二阀体140”设有第二限位部141”,第一阀体130”与第二阀体140”活动连接,第一限位部1321”适于与第二限位部141”止挡配 合以限制第一阀体130”脱离第二阀体140”,其中,第一限位部1321”和第二限位部141”中至少一者的至少一部分为变形部。其中,变形部能被挤压发生形变,且变形部被挤压发生形变时,第一阀体130”可与第二阀体140”分离。
例如,变形部为柔性材料的柔性件(也可称之为弹性体,具体例如为硅胶、橡胶等)或为具有弹性变形能力的弹性件(具体例如弹簧、卡簧、弹片等)。
本申请上述实施例提供的限压阀100”,第一阀体130”与第二阀体140”之间通过第一限位部1321”与第二限位部141”止挡配合进行限位,其中,设置第一限位部1321”和第二限位部141”中至少一者的至少一部分为变形部,这样,第一阀体130”与第二阀体140”之间大致形成柔性连接,如可以利用变形部受力变形以供第一限位部1321”与第二限位部141”之间柔性/弹性地卡接装配或柔性/弹性地脱扣解除限位,实现第一阀体130”与第二阀体140”之间更方便地装卸,这样,用户可方便、容易地拆装第一阀体130”和第二阀体140”,使得限压阀100”的日常拆装清洗更加便利,利于提升产品的卫生安全性。
且通过变形部的设计使得第一限位部1321”与第二限位部141”之间装卸过程中的损伤更小,可更好地保障产品反复装卸不损坏,更好地保障产品使用寿命。
具体实施例四
如图53至68所示,本实施例提供了一种限压阀100”,包括第一阀体130”和第二阀体140”。具体地,第一阀体130”设有第一限位部1321”;第二阀体140”设有第二限位部141”,第一阀体130”与第二阀体140”活动连接,第一限位部1321”适于与第二限位部141”止挡配合以限制第一阀体130”脱离第二阀体140”。
其中,第一阀体130”包括:阀本体131”和柔性件1352”。具体地,柔性件1352”设置在阀本体131”上,变形部由柔性件1352”构成。在某些具体实施例方式中,柔性件1352”可具体例如为硅胶、橡胶等。
更进一步地,如图64和图66所示,柔性件1352”设置在阀本体131” 上并且至少一部分相对于阀本体131”的表面凸起,柔性件1352”相对于阀本体131”的表面凸起的部位形成第一限位部1321”。这样,实现获得至少一部分为变形部的第一限位部1321”或第二限位部141”,且变形部被挤压发生形变时第一阀体130”可与第二阀体140”分离,这样,以实现第一阀体130”与第二阀体140”柔性连接便于装卸的目的的同时,产品结构更加简化,且也更方便于柔性件1352”的更换以及随产品型号的调整,这样,利用柔性件1352”的可替换性可克服老化影响,且也更利于产品结构在不同型号的限压阀100”之间适用,更利于产品的推广。
当然,本方案也并不局限于,也可设计对于第一限位部1321”的至少一部分为变形部,第一限位部1321”可以整体为变形部。也可以只有一部分为变形部,具体如,第一限位部1321”的一部分经由阀本体131”的凸起形成,凸起上附设有变形部,凸起与变形部构造第一限位部1321”。
且可以理解的是,在其他实施例中,也可设置第二限位部141”的一部分或全部为变形部。这时,第一限位部1321”可以随第一阀体130”的阀本体131”为非变形部,或者,第一限位部1321”也可同时为变形部。
进一步地,阀本体131”设有容置槽137”,柔性件1352”的一部分容置于容置槽137”内,另一部分伸出容置槽137”并相对于阀本体131”的表面凸起。产品的装配定位更加方便容易,产品组装更高效,且容置槽137”可对柔性件1352”形成限位作用,防止柔性件1352”受力偏位等问题,从而更利于保障第一阀体130”与第二阀体140”之间经由第一限位部1321”和第二限位部141”实现的限位精度。
当然,本设计也并不局限于此,在其他实施例中,可将柔性件1352”替换为弹性件,例如卡簧、弹簧、弹片等,使变形部由弹性件形成。弹性件与阀本体131”的具体设置形式可以参照柔性件1352”与阀本体131”之间的配合结构进行理解,如弹性件的一部分容置于容置槽137”内,另一部分伸出容置槽137”并相对于阀本体131”的表面凸起等。
在某些实施例中,如图66所示,第二阀体140”的至少一部分套设在第一阀体130”内。第一限位部1321”的至少一部分为变形部,如图65所示,第二限位部141”包括凸扣。这样,第二阀体140”的至少一部分穿入 第一阀体130”内并与第一阀体130”形成卡接限位,结构简单,装配方便,且第一阀体130”与第二阀体140”之间配合稳定性更好。
且其中,凸扣与变形部形成刚柔配合,这样,满足装卸便利性的同时,可以更好地兼顾第一限位部1321”与第二限位部141”之间的限位配合可靠性,使得第一阀体130”与第二阀体140”之间不容易脱离,从而保证产品可靠性。
更进一步地,如图65所示,凸扣上限定有适于引导变形部与凸扣卡接装配的卡接斜面1411”。通过凸扣设置卡接斜面1411”,这样,第一限位部1321”与第二限位部141”之间装配的过程中,变形部不容易被刮伤,从而更好地保障产品的质量和使用寿命。
在某些进一步的实施例中,更详细地,如图64和图66所示,第一阀体130”设有限位凸起1351”,限位凸起1351”与第一限位部1321”之间间隔地分布,使限位凸起1351”与第一限位部1321”之间形成适于供第二限位部141”活动的空间,第二限位部141”活动设置于空间内。
这样,利用第二限位部141”的活动自由度,既满足了第一阀体130”与第二阀体140”之间的相对活动需求,利用第一限位部1321”和限位凸起1351”对第二限位部141”的限位作用,又可以很好地满足第一阀体130”与第二阀体140”之间的防脱需求,实现第一阀体130”与第二阀体140”之间良好地活动连接装配,且产品的装卸更加方便,如拆卸时,施加外力使第二限位部141”从第一限位部1321”位置挤出即可,装配时,施加外力使第二限位部141”从第一限位部1321”位置挤入第一限位部1321”与限位凸起1351”之间即可,使用简单方便。
进一步地,如图64和图66所示,第一阀体130”限定有容纳孔133”,限位凸起1351”和第一限位部1321”分别相对于容纳孔133”的内壁面凸起,且限位凸起1351”与第一限位部1321”沿容纳孔133”的轴向间隔地分布;第二阀体140”的至少一部分位于容纳孔133”内,第二阀体140”沿容纳孔133”活动使第二限位部141”往返于限位凸起1351”与第一限位部1321”之间。这样,可以对第二阀体140”形成径向限位。使限位凸起1351”与第一限位部1321”沿容纳孔133”的轴向间隔地分布,这样,第二限位部 141”被限位于限位凸起1351”与第一限位部1321”之间,可以限制第一阀体130”与第二阀体140”之间的轴向活动量,并防止两者脱离,第一阀体130”与第二阀体140”之间的活动连接可靠性更好,且产品的装卸更加方便,如拆卸时,施加外力使第二阀体140”沿容纳孔133”自第一限位部1321”位置挤出即可,装配时,施加外力使第二阀体140”沿容纳孔133”自第一限位部1321”位置挤入即可,使用简单方便。
更详细地例如,容纳孔133”的内壁在轴向的某一位置处设有容置槽,容置槽沿容纳孔的周向设置成环形。柔性件为柔性圈(具体如橡胶圈、硅胶圈等,当然,也可替换为卡簧等弹性件),柔性圈一部分容置于容置槽内实现定位。
进一步地,限位凸起1351”可直接形成于第一阀体130”的阀本体131”上,以形成为第一阀体130”的阀本体131”的一部分。
在某些实施例中,第一阀体130”上设有提手环136”,方便用户将第一阀体130”提起。更详细地,提手环136”形成在容纳孔的一端,并沿容纳孔的周向设置。
进一步地,如图55所示,限压阀100”用于具有排气通道111”的盖体,其中,第二阀体140”被配置为适于与排气通道111”配合以打开或关闭排气通道111”;第一限位部1321”与限位凸起1351”上下间隔分布;第一阀体130”与第二阀体140”之间适于上下相对运动,且第一阀体130”被配置为通过上升或下降使第二限位部141”与限位凸起1351”或第一限位部1321”抵靠或分开,以改变第二阀体140”配合到排气通道111”上的重量。
其中,通过第一限位部1321”与限位凸起1351”上下间隔分布,这样,通过第二限位部141”与第一限位部1321”和/或限位凸起1351”的配合状态切换,可以更精确地调节第二阀体140”配合到排气通道111”上的重量,使得限压压力控制更加精准。以第一限位部1321”在下,限位凸起1351”在上为例说明,当第一阀体130”位置较低,使得限位凸起1351”搭靠在第二限位部141”上,第一阀体130”的重量施加于第二阀体140”,这样,第二阀体140”施加于排气通道111”的重量较大,限压压力相应较大(例如为高压);当第一阀体130”位置上升,第二限位部141”与限位凸起1351” 分开并且与第一限位部1321”分开,第一阀体130”的重量不会施加于第二阀体140”,这时施加于排气通道111”的重量为第二阀体140”的重力,限压压力相应降低(例如为低压);当第一阀体130”继续上升至第二限位部141”与第一限位部1321”抵靠,第二阀体140”的重量不会完全作用到排气通道111”上或使第二阀体140”完全离开排气通道111”,这时施加于排气通道111”的重量小于第二阀体140”的重力或施加于排气通道111”的重量为零,限压压力进一步降低或为零。
通过以上过程可以理解,第二限位部141”上下运动来配合上下分布的限位凸起1351”和第一限位部1321”,这样,对第二阀体140”施加于排气通道111”的重量的调控不会有额外的干扰,限压压力调节更加精确。
进一步地,第一限位部1321”的至少一部分为变形部,第一限位部1321”位于限位凸起1351”的下侧。这样,第二阀体140”承受内压浮起时,是利用限位凸起1351”来与第二限位部141”配合进行限位,可以更好地防止第二阀体140”被顶出,产品可靠性更高。
进一步地,限压阀100”还包括调压拨动件120”,调压拨动件120”与第一阀体130”可装卸地连接,并适于驱动第一阀体130”运动。
在本方案中,设置调压拨动件120”用于驱动第一阀体130”运动,如通过调压拨动件120”来联动第一阀体130”进行调压和复位,这样,外力(如调压驱动力或复位驱动力)基本作用于调压拨动件120”上,可以理解,外力的大小、方向等具有不可控性,如此设计可使得施加于第一阀体130”的力的大小、方向的可控性更好,这样第一阀体130”的限压可靠性和精准性更易于保障,提升产品的压控精度。
其中,设计调压拨动件120”与第一阀体130”可拆卸连接,这样,方便于限压阀100”进一步拆解,从而更方便与限压阀100”的拆洗,产品使用卫生性更好。
进一步地,调压拨动件120”和第一阀体130”中的一者设有导向筋134”,另一者设有凹槽121”,导向筋134”伸入凹槽121”内使调压拨动件120”与第一阀体130”之间啮合传动,其中,导向筋134”与凹槽121”之间可滑动,以供第一阀体130”相对于调压拨动件120”活动。结构更简单, 传动更高效,且具有装卸方便的优点。其中,设置导向筋134”与凹槽121”之间可滑动,以供第一阀体130”相对于调压拨动件120”活动,这样,第一阀体130”运动进行调压的过程不受调压拨动件120”干扰,精度更好。
如图53至图59所示,本申请第六方面的实施例提供了一种盖体,包括:盖本体31”和如本申请第五方面的任一实施例中所述的限压阀100”,盖本体31”设有排气通道111”;限压阀100”适于打开或封闭排气通道111”。
本申请上述实施例提供的盖体,通过设置有如本申请第五方面的任一实施例中所述的限压阀100”,从而具有上述全部有益效果,在此不再赘述。
进一步地,限压阀100”的第一阀体130”相对于盖本体31”可转动;盖本体31”与第一阀体130”之间限定有传动结构,当第一阀体130”相对于盖本体31”转动,传动结构联动第一阀体130”使第一阀体130”上升或下降,以改变限压阀100”的第二阀体140”配合到排气通道111”上的重量。
进一步地,如图68所示,盖本体31”和第一阀体130”中的一者设于调压凸块3216”,另一者设有调压面530”,调压凸块3216”与调压面530”抵靠,其中,调压面530”的至少一部分限定为调压斜坡,当第一阀体130”相对于盖本体31”转动,调压斜坡的不同位置与调压凸块3216”配合,使第一阀体130”相对于盖本体31”上升或下降。
这样,调压凸块3216”与调压斜坡之间可形成类似于凸轮机构的传动作用,当调压凸块3216”沿调压斜坡滑动的过程中,相应使得第一阀体130”相对于盖本体31”位置升高或降低,实现利用传动结构将第一阀体130”的转动输入转化为第一阀体130”上下位移运动的输出形式,且具有结构简单,组装方便,传动顺畅性好,抗振减振效果好等优点。
更进一步地,限压阀100”的调压拨动件120”设置在盖本体31”上并相对于盖本体31”可转动,且当调压拨动件120”转动驱动限压阀100”的第一阀体130”运动进行调压;如图57所示,盖本体31”上设有锁定结构(具体可参照附图中的锁定件200”进行理解),锁定结构适于与调压拨动件120”配合以锁定调压拨动件120”的位置;如图57所示,盖本体31”与调压拨动件120”之间设有弹性复位件301”,其中,当调压拨动件120”运 动,调压拨动件120”联动弹性复位件301”使弹性复位件301”变形,当锁定结构解除对调压拨动件120”的位置锁定,弹性复位件301”在自身恢复力的作用下复位,并驱动调压拨动件120”复位。其中,利用锁定结构锁定调压拨动件120”,这样,可以降低跳压风险,使得产品的调压功能更加可靠。利用弹性复位件301”用于驱动调压拨动件120”复位,这样,对调压拨动件120”解锁后,调压拨动件120”自动复位,无需用户对调压拨动件120”手动归位,使用操作更加方便、简洁,同时避免了用户使用调压功能时忘记对调压拨动件120”复位引起的下一次烹饪挡位不对带来的不良影响,如处于排气挡位(或排气位置)发生水烧干等风险和危害,提升产品的安全性。
更进一步地,如图53所示,盖体还包括:降噪盖50”,降噪盖50”用于盖在限压阀100”的外侧,对经限压阀排放的气流降噪。
进一步地,如图55所示,本实施例的盖体还包括:操作控制组件40”,操作控制组件40”配置为驱动的第二阀体140”打开。这样,用户可通过操作控制组件40”手动操作控制限压阀100”的第二阀体140”打开进行排气,产品使用更具灵活性和安装性。
举例而言,如图55所示,操作控制组件40”包括操作部41”(可以更具体为按钮)和传动杠杆42”。
如图58所示,盖体的盖本体31”包括面盖32”,面盖32”的内表面设有安装座,传动杠杆42”铰接于安装座,使得传动杠杆42”连接于面盖32”并相对于面盖32”可转动。
其中,如图55所示,传动杠杆42”以铰接位置为支点,并自支点向两侧分别延伸以分别形成传动臂。其中一条传动臂延伸至操作部41”的下方,另一条传动臂延伸至第二阀体140”的下方,当操作部41”向下按压其下方的传动臂,第二阀体140”下方的传动臂将第二阀体140”向上顶起,这样,第二阀体140”向上运动使得第二阀体140”的封堵部142”打开阀芯110”的排气通道111”,实现控制第二阀体140”打开进行排气。且传动杠杆42”通过力臂设计可以实现对操作部41”操作更加省力,也可以使得操作控制组件40”的布局更加灵活方便。
更进一步地,盖体还包括密封件60”,如图58所示,面盖32”的安装槽3201”底部设有密封装配槽3206”。如图55所示,密封件60”安装于密封装配槽3206”,传动杠杆42”的传动臂穿设于密封件60”,并伸入安装槽3201”内以对安装槽3201”内的第二阀体140”驱动。
具体实施例五
如图54和图56所示,本实施例提供了一种盖体,包括:限压阀100”、开合盖联动机构20”和盖本体31”。
其中,限压阀100”包括第一阀体130”、第二阀体140”和调压拨动件120”。
盖本体31”设有锁定结构和弹性复位件301”,锁定结构具体包括锁定件200”和第一弹性件400”等。
具体地,限压阀100”具有多个挡位,且多个挡位中的一者为初始挡位。限压阀100”用于调挡和限压,具体用于将烹饪腔内的压力限制在当前挡位所配套的限压压力以下。
锁定件200”适于锁定限压阀100”的挡位。这样,在将限压阀100”调至相应挡位后,利用锁定件200”对限压阀100”锁定挡位,可以使得限压阀100”的挡位维持稳定可靠,防止限压阀100”在非调节情形下跳挡,产品限压功能更精准可靠。
其中,锁定件200”用于与开合盖联动机构20”配合。具体地,当盖本体31”开盖,盖本体31”联动开合盖联动机构20”,并通过开合盖联动机构20”联动锁定件200”,使锁定件200”解除对限压阀100”的挡位锁定。
弹性复位件301”与限压阀100”配合,且当锁定件200”解除对限压阀100”的挡位锁定,弹性复位件301”驱动限压阀100”至初始挡位。
如此,当盖本体31”开盖,可以形成如下传动过程:
盖本体31”联动开合盖联动机构20”-开合盖联动机构20”联动锁定件200”运动,使锁定件200”解除对限压阀100”的挡位锁定-弹性复位件301”驱动限压阀100”至初始挡位。
利用上述传动过程,形成了盖本体31”开盖-限压阀100”至初始挡位的自动触发响应过程。无需用户对限压阀100”手动归位,使用操作更加方便、 简洁,同时避免了用户使用调挡功能时忘记对限压阀100”复位引起的水烧干等风险和危害,提升产品的安全性。
且本结构中,驱动限压阀100”复位的动力来自于弹性复位件301”,这样可以有效保障开合盖联动机构20”的精准性不受限压阀100”干扰,保证产品的开合盖功能稳定、可靠,有效保障产品安全。
进一步地,如图54所示,锁定件200”与盖本体31”之间设有第一弹性件400”。具体地,第一弹性件400”与锁定件200”配合;锁定件200”设置在盖本体31”上并相对于盖本体31”可活动;当锁定件200”运动以解除对限压阀100”的挡位锁定,锁定件200”使第一弹性件400”变形;当第一弹性件400”弹性恢复,第一弹性件400”的弹力驱动锁定件200”朝限压阀100”运动,使锁定件200”锁定限压阀100”的挡位。这样,在每次对限压阀100”调挡之后,锁定件200”可以自动、及时、准确地对限压阀100”进行挡位锁定,无需用户手动锁挡,产品使用操作更加简单、方便。
详细举例地,如图54所示,锁定件200”具体设置在盖本体31”的面盖32”内侧,并相对于面盖32”在第一位置与第二位置之间可活动,锁定件200”在第一位置与限压阀100”配合以锁定限压阀100”的挡位(如图54和图57所示),锁定件200”在第二位置解除对限压阀100”的挡位锁定。其中,第一弹性件400”与锁定件200”抵靠或相连,当锁定件200”在第二位置,锁定件200”拉伸过压缩第一弹性件400”使第一弹性件400”变形,当第一弹性件400”弹性恢复,驱动锁定件200”向第一位置运动。
这样,限压阀100”复位过程中,开合盖联动机构20”联动锁定件200”使锁定件200”至第二位置以解除对限压阀100”的挡位锁定后,弹性复位件301”驱动限压阀100”自动复位至初始挡位,当开合盖联动机构20”对锁定件200”的作用力撤去后,锁定件200”在第一弹性件400”弹力的作用下自动复位至第一位置,并将限压阀100”锁定于该初始挡位;再如,限压阀100”调挡过程中,锁定件200”在第一位置和第二位置之间往复运动从而具有一定的活动量,这样,对限压阀100”调节挡位时,锁定件200”向第二位置运动可以对限压阀100”的调节挡位运动进行避让,使锁定件200”在一定程度上减少调挡过程中对限压阀100”的干涉量,限压阀100”被调 节至相应挡位后,锁定件200”在第一弹性件400”弹力的作用下自动复位至第一位置,并将限压阀100”锁定于当前挡位,使得限压阀100”的挡位在一定程度上维持稳定,降低跳挡风险。
更详细地,如图54所示,第一弹性件400”为伸缩弹簧,其一端与锁定件200”抵靠,另一端与盖本体31”抵靠,例如具体与盖本体31”的面盖32”抵靠。当然,本设计并不局限于此,在其他实施例中,第一弹性件400”也可采用为弹片、弹性硅胶等。
在某些具体实施例中,如图54和图61所示,为对第一弹性件400”的伸缩进行导向以提升第一弹性件400”的变形效果,在锁定件200”上限定有导向杆240”,第一弹性件400”的至少一部分套装在导向杆240”的外侧,使得第一弹性件400”沿导向杆240”进行伸缩变形。
更进一步地,如图54、图57和图61所示,锁定件200”上设有第一限位结构210”,盖本体31”限定有第二限位结构3205”;当锁定件200”运动以解除对限压阀100”的挡位锁定(例如当锁定件200”位于第二位置),第一限位结构210”与第二限位结构3205”分开。
当第一弹性件400”的弹力驱动锁定件200”使锁定件200”锁定限压阀100”的挡位(例如当锁定件200”位于第一位置),弹力使第一限位结构210”抵靠在第二限位结构3205”上。这样,使得锁定件200”的装配具有一定的预紧力,锁定件200”的组装和运动平稳性更好,这样可以防止调挡过程中限压阀100”带动锁定件200”导致锁定件200”偏位,使得锁定件200”位置精度更加可靠。且在满足预紧力提升平稳性的同时,通过第一限位结构210”和第二限位结构3205”抵靠可以分担一部分弹力,这样可以更好地控制锁定件200”对限压阀100”的锁定作用力,以更好地在满足锁定需求的同时,防止限压阀100”受力过大,如此以更好地保障限压阀100”的位置精度和运动精度,并且避免调挡阻力过大的问题。
更详细地,如图61所示,锁定件200”具体轴体,轴体上限定有轴肩结构,轴肩结构作为第一限位结构210”。如图57所示,盖体上设有复位引导槽3212”,锁定件200”的一部分穿过复位引导槽3212”与限压阀100”配合以对限压阀100”锁定挡位,且复位引导槽3212”同时作为第二限位结 构3205”,锁定件200”的第一限位结构210”与复位引导槽3212”抵靠配合对锁定件200”限位。结构简单,加工方便,进一步强化锁定件200”的稳定性。
进一步地,如图57所示,盖本体31”限定有轨道槽3210”,锁定件200”的一部分位于轨道槽3210”内,且锁定件200”的运动经由轨道槽3210”导向和限位,可以使得锁定件200”的运动更加精准,且使得锁定件200”与限压阀100”的配合更加精准,更进一步强化了锁定件200”对限压阀100”的限位可靠性,从而提升对限压阀100”的挡位锁定的可靠性。
更进一步地,如图57所示,轨道槽3210”与第二限位结构3205”之间具有间距,可以进一步提升对锁定件200”的导向效果,且可以防止锁定件200”以第二限位结构3205”为支点发生偏转,进一步提升锁定件200”的装配可靠性和稳定性。
另外,盖体装置上还设有复位引导槽3212”,复位引导槽3212”位于轨道槽3210”与限压阀100”之间,锁定件200”的一端自复位引导槽3212”穿过与限压阀100”配合以对限压阀100”锁定,其中,复位引导槽3212”与轨道槽3210”之间间隔地分布。
更进一步地,盖体装置的面盖32”或内盖上形成有第二限位结构3205”,且第二限位结构3205”为挡筋且该挡筋构造出复位引导槽3212”,锁定件的一部分穿设在复位引导槽3212”内,锁定件上设有轴肩,轴肩作为第一限位结构210”并适于与复位引导槽3212”两侧的第二限位结构3205”抵靠或分离以对锁定件限位。
在某些实施例中,如图54所示,其中,限压阀100”位于盖本体31”上,限压阀100”的至少一部分相对于盖本体31”可转动,且限压阀100”的至少一部分转动使限压阀100”的挡位改变。采用旋转调压的限压阀100”,具有调压操作简单、方便,且这样的结构在不浪费产品空间的前提下,可拥有更大的调节行程,这样,可以形成更多的挡位,且也利于对挡位的精细化调控。
锁定件200”与限压阀100”配合,并限制限压阀100”的至少一部分转动以锁定限压阀100”的挡位。锁定件200”通过限制限压阀100”转动实现 对限压阀100”锁定挡位,对限压阀100”的挡位锁定简单可靠。
进一步地,如图57所示,限压阀100”限定有多个配合槽102”,且限压阀100”的多个挡位与多个配合槽102”配套;多个配合槽102”沿限压阀100”的周向间隔地排列设置,锁定件200”的一部分伸入配合槽102”内限制限压阀100”转动,使限压阀100”锁定于与配合槽102”配套的挡位。该结构中,通过锁定件200”与配合槽102”的侧壁干涉,能更可靠地限制限压阀100”转动,从而更加可靠地对限压阀100”锁定挡位。
其中,多个配合槽102”的设计可以实现对限压阀100”在不同挡位相应锁定,对限压阀100”锁定挡位更加全面可靠,且调挡过程中,锁定件200”通过沿多个配合槽102”依次配合运动,可以产生段感体验,使得挡位切换通过相应的段感进行外化体现,对挡位切换的指示效果更好,且也提升了产品的操作体验。
进一步地,如图57和图62所示,限压阀100”的调压拨动件120”具有侧面101”,侧面101”局部凹陷形成配合槽102”。这样,既能满足锁定件200”与凹陷的配合槽102”之间插接配合对限压阀100”限制转动以锁定挡位,又可以更好地兼顾调挡过程中锁定件200”在不同配合槽102”之间运动和切换,这样,调挡的阻力更小,操作顺畅性更好。
在某些具体实施例中,如图57所示,配合槽102”的内壁面呈凹弧形。这样,锁定件200”可以更容易地进出配合槽102”,不容易出现卡顿等问题,操作体验好,且对锁定件200”的损伤也小,更利于保障产品的寿命。
在某些具体实施例中,如图57所示,侧面101”的一部分位于相邻配合槽102”之间并过渡衔接相邻配合槽102”,且相邻配合槽102”之间的侧面101”与配合槽102”的边缘呈弧形过渡103”。这样,锁定件200”在不同配合槽102”之间切换时流畅性更好,不容易出现卡顿现象,操作体验好,且对锁定件200”的损伤也小,更利于保障产品的寿命。
在某些具体实施例中,如图61所示,锁定件200”上构造有凸弧面220”,凸弧面220”与限压阀100”的配合槽102”配合以锁定限压阀100”。这样,利用凸弧面220”,当限压阀100”转动进行调挡过程中,凸弧面220”沿限压阀100”的侧面101”滑动的阻力和损伤更小,可以更好地兼顾调挡 的顺畅性并降低限压阀100”和锁定件200”损伤。
更详细地,如图61所示,锁定件200”的轴体轴向的一端的端面限定为该凸弧面220”,锁定件200”以凸弧面220”部位与限压阀100”的侧面101”及配合槽102”配合,具体地,限压阀100”转动时,凸弧面220”沿侧面101”滑动并在不同配合槽102”之间切换,实现对不同挡位锁定。
在某些具体实施例中,如图54和图55所示,盖本体31”上限定有排气通道111”。排气通道111”用于与烹饪腔连通,当排气通道111”打开,供烹饪腔排气,当排气通道111”关闭,使得烹饪腔在排气通道111”处密封。
其中,如图54和图55所示,示意了调压拨动件120”和阀体组件。
如图54所示,调压拨动件120”相对于盖本体31”可转动,弹性复位件301”与调压拨动件120”配合并适于驱动调压拨动件120”转动复位,锁定件200”适于与调压拨动件120”配合并限制调压拨动件120”转动。
阀体组件用于打开或封堵排气通道111”,其中,调压拨动件120”与阀体组件相连,且调压拨动件120”配置为通过转动联动阀体组件,使阀体组件对排气通道111”的限压压力改变。其中,弹性复位件301”与调压拨动件120”配合并适于驱动调压拨动件120”转动复位,锁定件200”适于与调压拨动件120”配合并限制调压拨动件120”转动。
更具体地,阀体组件包括相互连接的第一阀体130”和第二阀体140”。调压拨动件120”与第一阀体130”相连,调压拨动件120”转动时带动第一阀体130”相对排气通道111”上升或下降,以改变阀体组件配合在排气通道111”上的重量。
第二阀体140”上设有封堵部142”,封堵部142”用于封闭或打开排气通道111”。第二阀体140”相对于第一阀体130”可上下运动,且第二阀体140”上下运动打开或关闭排气通道111”。
详细举例而言,盖体装置上设有阀芯110”,阀芯110”内限定有排气通道111”。具体地,当封堵部142”压在阀芯110”上,封堵部142”对阀芯110”的排气通道111”密封,当第二阀体140”被顶起使得封堵部142”打开排气通道111”,烹饪腔可沿排气通道111”排气。当然,本设计并不局限 于此,在其他实施例中,排气通道111”也可经由盖体装置的锅盖33”、内盖等上的排气孔限定出。
其中,以限压阀100”具有无压挡/排气挡、低压挡和高压挡,并可在无压挡/排气挡、低压挡和高压挡之间切换为例进行详细举例说明:
调压拨动件120”旋转的同时,第一阀体130”实现旋转并上升,第一阀体130”上升后,第一阀体130”的重量被盖体装置的面盖32”承受,没有压在阀芯110”的排气口上,故此时只有第二阀体140”的重量压在阀芯110”的排气口处,实现限压阀100”切换为低压挡位,故此时烹饪设备的烹饪腔内的压力较低时就可以将第二阀体140”推动而排气,实现低压烹饪。
当调压拨动件120”继续旋转,第一阀体130”实现旋转并继续上升,第一阀体130”将第二阀体140”顶起,例如,第一阀体130”的变形部(具体如硅胶体、橡胶体等)将第二阀体140”顶起,第一阀体130”和第二阀体140”整体离开阀芯110”,第一阀体130”和第二阀体140”均没有压在阀芯110”的排气口上,排气通道111”打开,实现限压阀100”切换为无压挡位或排气挡位,实现无压烹饪或排气。
当第一阀体130”在调压拨动件120”的带动下复位时,第一阀体130”下降,第一阀体130”压在第二阀体140”上,具体如,第一阀体130”的限位凸起1351”压在第二阀体140”的第二限位部上,从而使得第二阀体140”和第一阀体130”的重量都压在阀芯110”的排气口上,实现限压阀100”切换为高压挡位,故此时烹饪设备的烹饪腔内的压力要达到较高才可以将第二阀体140”推动而排气,实现高压烹饪,由此通过改变阀体组件压在阀芯110”的排气口上的重量,从而实现调节烹饪设备内的烹饪腔压力变化的目的。
进一步地,如图63所示,第一阀体130”和盖本体31”之间形成有传动结构,其中,当所述第一阀体130”相对于盖本体31”转动,第一阀体130”与盖本体31”之间具体经由传动结构进行传动,使第一阀体130”上下活动进行调挡。
举例而言,如图68所示,传动结构包括调压凸块3216”(调压凸块3216”具体为支撑柱)和调压斜坡(具体参照附图中的第一调压斜坡和/或 第二调压斜坡进行理解),调压斜坡包括斜面和弧面中的一种或多种的组合,其中,调压凸块3216”和调压斜坡中的一者设置在第一阀体130”上,另一者设置在盖本体31”上;当第一阀体130”转动,调压凸块3216”沿调压斜坡滑动,其中,调压斜坡的不同位置与调压凸块3216”配合,使第一阀体130”相对于盖本体31”升高或降低。
这样,调压凸块3216”与调压斜坡之间可形成类似于凸轮机构的传动作用,当调压凸块3216”沿调压斜坡滑动的过程中,相应使得第一阀体130”相对于盖本体31”位置升高或降低,实现利用传动结构将第一阀体130”的转动输入转化为第一阀体130”上下位移运动的输出形式,且具有结构简单,组装方便,传动顺畅性好,抗振减振效果好等优点。
进一步地,如图63所示,第一阀体上限定有调压面530”,传动结构形成为调压面530”的一部分。更具体地,调压面530”包括第一级调压平面531”、第二级调压平面532”、第三级调压平面533”、第一调压斜坡534”和第二调压斜坡535”,第一调压斜坡534”过渡在第一级调压平面531”与第二级调压平面532”之间,且第一调压斜坡534”自第一级调压平面531”向第二级调压平面532”位置升高,第二调压斜坡535”自第二级调压平面532”向第三级调压平面533”位置升高。
另外,如图70、图71和图72所示,调压拨动件120”设有侧面101”,且侧面101”上限定有3个配合槽102”,分别为配合槽102a”、配合槽102b”、配合槽102b”。配合槽102a”对应高压挡位,配合槽102b”对应低压挡位,配合槽102b”对应无压挡位或排气挡位。
当调压凸块3216”抵靠于第三级调压平面533”上,如图69和图70所示,限压阀100”处于初始挡位(也即高压挡位),第一阀体130”的位置最低,且锁定件200”的凸弧面220”配合于对应高压挡位的配合槽102a”内以锁定调压拨动件120”,烹饪腔内进行高压烹饪。
当调压凸块3216”抵靠于第二级调压平面532”上,如图71所示,第一阀体130”被抬高且其重量支撑在盖本体31”上,限压阀100”处于低压挡位,且锁定件200”的凸弧面220”配合于对应低压挡位的配合槽102b”内以锁定调压拨动件120”,烹饪腔内进行低压烹饪。
当调压凸块3216”抵靠于第一级调压平面531”上,如图72所示,第一阀体130”继续被抬高并带动第二阀体140”一起上升,限压阀100”处于无压挡位或排气挡位,且锁定件200”的凸弧面220”配合于对应无压挡位或排挡位的配合槽102b”内以锁定调压拨动件120”,阀体组件位置最高,烹饪腔内进行无压烹饪或排气。
通过本方案,且通过本结构,实现第一阀体130”转动形成上下运动进行限压压力调节的目的的同时,第二阀体140”的限压过程基本不受影响,限压过程更加精确可靠,且通过阀体组件转动以进行上下运动联动,实现阀体组件配重调节,整个结构简单化,且也方便阀体组件整体拆出清洗,日常使用更加方便。
当然,本设计并不局限于此,在其他实施例中,也可采用螺纹结构实现第一阀体转动同时形成上下运动的目的。
在某些具体实施例中,调压拨动件120”与第一阀体130”之间的连接使得第一阀体130”随调压拨动件120”转动,并使得第一阀体130”相对于调压拨动件120”可上下运动。
例如,调压拨动件120”具有环形体,并围成上下贯穿的安装孔,第一阀体130”位于该安装孔。第一阀体130”的侧壁的外表面和环形体侧壁的内表面中一者设有导向筋134”,另一者设有凹槽121”,导向筋134”沿上下方向延伸设置,凹槽121”套装在导向筋134”的外侧形成导向筋134”与凹槽121”啮合,凹槽121”为上下延伸设置的滑槽,导向筋134”沿凹槽121”可上下滑动,这样,既满足调压拨动件120”与第一阀体130”之间转动联动,也使得第一阀体130”与调压拨动件120”之间可上下相对运动。使得调压拨动件120”转动时,第一阀体130”可相对于调压拨动件120”上升或下降。
更详细地,如图62所示,调压拨动件120”呈环形,并围成上下贯穿的安装孔,第一阀体130”位于该安装孔内并可沿该安装孔上下活动。当然,本实施例并不局限于此,在其他实施例中,根据需求也可设计调压拨动件随第一阀体上下运动。或者,在另一些实施例中,根据需求也可设计调压拨动件为第一阀体的一部分,如调压拨动件与第一阀体形成为一体。
进一步地,如图62所示,调压拨动件120”上设有拨钮122”。用户通过拨钮122”驱动调压拨动件120”转动进行调挡,产品操作可更加方便、简单。
进一步地,如图55、图57和图59所示,盖本体31”具有面盖32”,面盖32”上设有安装槽3201”。如图3所示,调压拨动件120”的至少一部分位于安装槽3201”内。
其中,如图59和图62所示,安装槽3201”的侧壁和调压拨动件120”中的一者上设有旋转导槽123”,另一者上设有旋转限位凸块3202”,旋转限位凸块3202”伸入旋转导槽123”内并沿旋转导槽123”滑动,且旋转限位凸块3202”与旋转导槽123”配合限制调压拨动件120”离开安装槽3201”。
更详细地,旋转导槽123”沿其所在的安装槽3201”侧壁或调压拨动件120”的周向延伸,旋转限位凸块3202”伸入旋转导槽123”内,这样,调压拨动件120”转动的过程中,旋转限位凸块3202”沿旋转导槽123”滑动。
其中,旋转导槽123”具有上侧壁和下侧壁,上侧壁与下侧壁之间间隔并围成供旋转限位凸块3202”滑动运动的空间。旋转限位凸块3202”位于上侧壁与下侧壁之间,利用上侧壁和下侧壁对旋转限位凸块3202”限位,限制调压拨动件120”脱离安装槽3201”。
更进一步地,安装槽3201”的侧壁和调压拨动件120”中的一者上沿周向排列布置有多个旋转导槽123”,另一者上相应设有多个旋转限位凸块3202”(具体例如图59所示,安装槽3201”的侧壁上设有3个旋转限位凸块3202”),多个旋转限位凸块3202”与多个旋转导槽123”之间一一对应配合,这样,形成对调压拨动件120”周向多个位置进行支撑和限位,进一步提升调压拨动件120”的装配稳定性。
当然,本设计并不局限于此,在其他实施例中,也可设计1个旋转限位凸块3202”与1个旋转导槽123”配合。或者,根据需求,也可设计2个、4个、5个、6个等旋转限位凸块3202”,旋转导槽123”的数量根据旋转限位凸块3202”的数量相应设计。
进一步地,如图59所示,盖本体31”限定有一个或多个调压凸块 3216”,第一阀体130”上设有多个调压面530”,且调压面530”与调压凸块3216”之间一对一配套。对第一阀体130”支撑更平稳。
具体例如图59所示,盖本体31”的面盖32”上设有安装槽3201”,安装槽3201”内设有调压凸块3216”,调压凸块3216”为相对于安装槽3201”的内底面凸起的凸筋或支撑柱。调压凸块3216”的数量为3个,且3个调压凸块3216”沿安装槽3201”的周向间隔地排列布置,以对第一阀体130”更平稳地支撑。当然,调压凸块3216”的数量并不局限为3个,在其他实施例中,调压凸块3216”的数量也可设计为1个、2个、4个、5个甚至更多。
进一步地,如图64、图65和图66所示,第一阀体130”和第二阀体140”中的一者设有第三限位结构,第三限位结构包括间隔分布的限位凸起1351”和经由柔性件1352”限定出的第一限位部1321”,另一者设有第二限位部141”,第二限位部141”伸入限位凸起1351”与第一限位部1321”之间,且第二阀体140”上下运动使第二限位部141”往返于限位凸起1351”与第一限位部1321”之间。这样可以防止第二阀体140”脱离第一阀体130”,有效保障第一阀体130”与第二阀体140”之间连接及相对位置准确性,有效保障调挡功能准确、可靠。
详细举例地,如图64所示,变形部与第一阀体130”的阀本体131”为分体部件。例如,第一阀体130”的阀本体131”上设有容置槽137”,变形部的一部分容置于容置槽137”,并通过容置槽137”限位实现装配在第一阀体130”的阀本体131”上。变形部的另一部分伸出容置槽137”,并自第一阀体130”的阀本体131”的表面凸起,其中,变形部相对于第一阀体130”的表面凸起的部位作为一个第一限位部1321”,该变形部与第一阀体130”的表面上的限位凸起1351”之间间隔分布限定出供第二限位部141”活动的空间,第二阀体140”相对于第一阀体130”上下运动,使得第二限位部141”在变形部与限位凸起1351”之间来回运动。
更详细例如,变形部为硅胶件。
在某些具体实施例中,开合盖联动机构20”包括自锁滑块21”,自锁滑块21”设置在盖本体31”上,且盖本体31”开盖联动自锁滑块21”运动, 并通过自锁滑块21”联动锁定件200”,使锁定件200”解除对限压阀100”的挡位锁定。该结构满足开盖触发调压拨动件120”自动复位的同时,具有结构简单,成本低的优点,简言之,可以利用盖体原本具有的自锁滑块21”来对调压拨动件120”进行开盖触发控制,改造成本低,且部件之间的相适性好,改造简单、方便。
更详细地,如图55所示,盖本体31”设有锁扣结构。更详细举例地,盖本体31”可包括面盖32”和位于面盖32”的内侧的锅盖33”,锁扣结构可具体形成在锅盖33”上并自锅盖33”的内侧凸伸。或者,盖本体31”可包括面盖32”和位于面盖32”的内侧的锁扣部件,锁扣结构具体形成在锁扣部件上。可以理解,锁扣结构用于与烹饪锅的锅牙扣合以锁紧锅盖33”与烹饪锅,从而使盖本体31”盖合,且锁扣结构与锅牙之间可以解除扣合以使盖本体31”开盖。
如图60所示,自锁滑块21”设有推杆24”(推杆24”也可称之为自锁销)和第三弹性件25”,第三弹性件25”套装在推杆24”的外侧。锅盖33”上设有通孔,推杆24”的一部分沿通孔伸至锅盖33”的内侧。
其中,盖本体31”开盖的过程中,锅牙会向外顶起推杆24”,使推杆24”向外运动并压缩第三弹性件25”。其中,由于推杆24”设置在自锁滑块21”上,推杆24”向外运动的过程中会联动自锁滑块21”向外运动。从而实现了盖本体31”开盖对自锁滑动的联动作用。
另外,本领域技术人员可以理解,自锁滑块21”具有使盖本体31”自锁的功能。具体地,如图60所示,自锁滑块21”上设有浮子孔23”,如图55所示,盖本体31”上限定有浮子70”,当浮子70”浮起,浮子70”穿过浮子孔23”,这样,浮子70”限制自锁滑块21”向外运动,相应地,利用推杆24”可反过来限制锅牙运动,从而限制锅牙与锁扣结构解除扣合,实现盖本体31”自锁。相应地,该情况下,自锁滑块21”也不会通过锁定件200”使限压阀100”自动向初始位置复位。
进一步举例而言,止挡部22”为设置在自锁滑块21”上的凸板或卡钩,止挡结构230为止挡凸块,止挡凸块的至少一部分朝自锁滑块21”延伸,当盖本体31”开盖,凸板或卡钩拉动止挡凸块,使锁定件朝远离限压阀100” 的方向运动。
当然,本方案并不局限于此,在其他实施例中,也可省略锁定件200”,其对调压拨动件的锁定作用经由自锁滑块21”实现,例如,在自锁滑块21”上设置凸起来与配合槽102”配合,以发挥对调压拨动件的锁定功能。且这样也同时也可以实现开盖自动对调压拨动件解锁的目的。
在某些具体实施例中,弹性复位件301”具体为弹簧,当然,根据需求可以为弹片、弹性橡胶等。
弹性复位件301”与盖本体31”及限压阀100”抵靠配合,限压阀100”运动联动弹性复位件301”使弹性复位件301”变形,弹性复位件301”弹性恢复时带动限压阀100”复位。
进一步地,弹性复位件301”沿限压阀100”的周向延伸设置呈弧形。
更详细地,如图59和图57所示,盖本体31”具有面盖32”,面盖32”上设有装配槽3206”,装配槽3206”沿限压阀100”的周向延伸设置呈弧形。弹性复位件301”容置于装配槽3206”内并沿装配槽3206”伸缩。一方面,装配槽3206”的设置更方便弹性复位件301”的安装和定位,另一方面,装配槽3206”的导向作用可以良好地引导弹性复位件301”的变形方向,这样,弹性复位件301”的变形效果更好,不容易发生不可逆变形,使用寿命更长。
更详细举例地,如图57、图59及图67所示,装配槽3206”延伸方向的一端形成有止挡筋3207”,另一端形成安装区域3208”。
限压阀100”的调压拨动件上限定有驱动块124”,驱动块124”与限压阀100”的调压拨动件的中心线之间具有间距。弹性复位件301”的一端与装配槽3206”的一端部抵靠,安装区域3208”供驱动块124”伸入,弹性复位件301”的另一端与驱动块124”抵靠,限压阀100”的至少一部分相对于盖本体31”可转动,限压阀100”的至少一部分转动时压缩弹性复位件301”,弹性复位件301”的恢复力使限压阀100”复位。
当然,本方案并不局限于此,弹性复位件301”也可采用扭簧。
