背景技术Background Art
目前，市场上的压力锅一般包括锅体以及盖设在锅体上的锅盖，锅盖包括内衬以及位于内衬下方的锁盖，锁盖上具有盖牙，锅体上具有锅牙。内衬上设置有转杆，通过转动转杆实现锅盖与锅体的锁定和解锁。当锅内热气较多时，用户将锅盖盖在锅体上会使得锅内的压强较大，此时锅牙和盖牙的摩擦力较大，用户很难转动转杆，从而影响锅盖开合的顺畅性，使得用户使用体验差。At present, the pressure cooker on the market generally includes a pot body and a pot cover arranged on the pot body, the pot cover includes an inner lining and a locking cover located below the inner lining, the locking cover has a cover tooth, and the pot body has a pot tooth. A rotating rod is arranged on the inner lining, and the pot cover and the pot body are locked and unlocked by rotating the rotating rod. When there is a lot of hot air in the pot, the user will cover the pot body with the pot cover, which will increase the pressure in the pot. At this time, the friction between the pot teeth and the cover teeth is large, and it is difficult for the user to rotate the rotating rod, thereby affecting the smoothness of the pot cover opening and closing, resulting in a poor user experience.
发明内容Summary of the invention
本发明的主要目的在于提供一种电压力锅，以解决现有技术中的电压力锅的用户使用体验差的问题。The main purpose of the present invention is to provide an electric pressure cooker to solve the problem of poor user experience of the electric pressure cooker in the prior art.

When the rotating part is in the unlocked position, and in the process of the rotating part rotating from the unlocked position to the middle position, the pushing top part cooperates with the pressure limiting valve to connect the gas in the pot body with the outside atmosphere. When the rotating part rotates from the middle position to the locked position, the pushing top part is away from the pressure limiting valve, and when the rotating part rotates to the locked position, the pushing top part no longer applies force to the pressure limiting valve.
应用本发明的技术方案，电压力锅包括可枢转地设置在内衬上的推顶部，推顶部被转动部驱动，当转动部位于解锁位置时，以及转动部由解锁位置转动至中间位置的过程中，推顶部与限压阀抵顶配合以使锅体内的气体与外界大气连通，当转动部由中间位置向锁定位置转动时，推顶部远离限压阀，当转动部转动至锁定位置时，推顶部不再向限压阀施力。在上述结构中，由于转动部由解锁位置转动至中间位置的过程中，推顶部一直顶推限压阀，因此锅内的热气能够尽量多的排至外界，从而减小了锅内的压力，提高了锅盖开合的顺畅性，改善了用户使用体验，解决了现有技术中的电压力锅的用户使用体验差的问题。此外，由于当转动部转动至锁定位置时，推顶部不再向所述限压阀施加外力，因此上述结构能够保证限压阀在烹饪阶段时正常工作，实现高压烹煮的目的。According to the technical solution of the present invention, the electric pressure cooker includes a push top portion pivotally arranged on the inner lining, the push top portion is driven by the rotating part, when the rotating part is in the unlocking position, and in the process of the rotating part rotating from the unlocking position to the middle position, the push top portion and the pressure limiting valve are pressed against each other to make the gas in the pot body communicate with the outside atmosphere, when the rotating part rotates from the middle position to the locking position, the push top portion is away from the pressure limiting valve, and when the rotating part rotates to the locking position, the push top portion no longer applies force to the pressure limiting valve. In the above structure, since the push top portion pushes the pressure limiting valve all the time during the process of the rotating part rotating from the unlocking position to the middle position, the hot air in the pot can be discharged to the outside as much as possible, thereby reducing the pressure in the pot, improving the smoothness of the opening and closing of the pot cover, improving the user experience, and solving the problem of poor user experience of the electric pressure cooker in the prior art. In addition, since the push top portion no longer applies external force to the pressure limiting valve when the rotating part rotates to the locking position, the above structure can ensure that the pressure limiting valve works normally during the cooking stage, and achieve the purpose of high-pressure cooking.

具体实施方式DETAILED DESCRIPTION
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
如图1至图7所示，实施例一的电压力锅包括：锅体10、锅盖20、限压阀30、转动部40以及推顶部50。其中，锅体10用以盛放待烹饪的食物，锅体10上具有锅牙。锅盖20盖设在锅体10上，锅盖20包括锁盖21以及设置在锁盖21上的内衬22，锁盖21上具有与锅牙配合的盖牙。限压阀30设置在锅盖20上，当锅体10内的压力达到预定压力值时，限压阀30连通锅体10内的气体与外界大气，当锅体10内的压力未达到预定压力值时，限压阀30隔绝锅体10内的气体与外界大气。转动部40可枢转地设置在内衬22上并与锁盖21连接，锁盖21在转动部40的驱动下转动，转动部40具有锁定位置、解锁位置以及位于锁定位置与解锁位置之间的中间位置，当转动部40转动至解锁位置时，锅牙与盖牙分离，当转动部40位于锁定位置时，锅牙与盖牙配合，当转动部40转动至中间位置时，锅牙和盖牙干涉配合。推顶部50可枢转地设置在内衬22上，推顶部50被转动部40驱动，当转动部40位于解锁位置时，以及转动部40由解锁位置转动至中间位置的过程中，推顶部50与限压阀30抵顶配合以使锅体10内的气体与外界大气连通，当转动部40由中间位置向锁定位置转动时，推顶部50远离限压阀30，当转动部40转动至锁定位置时，推顶部50不再向限压阀30施力。As shown in Figures 1 to 7, the electric pressure cooker of the first embodiment includes: a pot body 10, a pot cover 20, a pressure limiting valve 30, a rotating part 40 and a pushing part 50. Among them, the pot body 10 is used to hold food to be cooked, and the pot body 10 has pot teeth. The pot cover 20 is covered on the pot body 10, and the pot cover 20 includes a locking cover 21 and a lining 22 arranged on the locking cover 21, and the locking cover 21 has a cover tooth that matches the pot teeth. The pressure limiting valve 30 is arranged on the pot cover 20. When the pressure in the pot body 10 reaches a predetermined pressure value, the pressure limiting valve 30 connects the gas in the pot body 10 with the outside atmosphere. When the pressure in the pot body 10 does not reach the predetermined pressure value, the pressure limiting valve 30 isolates the gas in the pot body 10 from the outside atmosphere. The rotating part 40 is pivotally arranged on the lining 22 and connected to the locking cover 21. The locking cover 21 rotates under the driving of the rotating part 40. The rotating part 40 has a locking position, an unlocking position and an intermediate position between the locking position and the unlocking position. When the rotating part 40 rotates to the unlocking position, the pot teeth and the cover teeth are separated. When the rotating part 40 is in the locking position, the pot teeth and the cover teeth cooperate. When the rotating part 40 rotates to the intermediate position, the pot teeth and the cover teeth interfere with each other. The pushing part 50 is pivotally arranged on the lining 22. The pushing part 50 is driven by the rotating part 40. When the rotating part 40 is in the unlocking position and during the rotating part 40 rotating from the unlocking position to the intermediate position, the pushing part 50 abuts against the pressure limiting valve 30 to connect the gas in the pot body 10 with the outside atmosphere. When the rotating part 40 rotates from the intermediate position to the locking position, the pushing part 50 is away from the pressure limiting valve 30. When the rotating part 40 rotates to the locking position, the pushing part 50 no longer applies force to the pressure limiting valve 30.
应用实施例一的技术方案，电压力锅包括可枢转地设置在内衬22上的推顶部50，推顶部50被转动部40驱动，当转动部40位于解锁位置时，以及转动部40由解锁位置转动至中间位置的过程中，推顶部50与限压阀30抵顶配合以使锅体10内的气体与外界大气连通，当转动部40由中间位置向锁定位置转动时，推顶部50远离限压阀30，当转动部40转动至锁定位置时，推顶部50不再向限压阀30施力。在上述结构中，由于转动部40由解锁位置转动至中间位置的过程中，推顶部50一直顶推限压阀30，因此锅内的热气能够尽量多的排至外界，从而减小了锅内的压力，进而减小了合盖时锅牙和盖牙之间产生的摩擦力，或者避免了锅牙和盖牙之间产生摩擦，提高了锅盖20开合的顺畅性，改善了用户使用体验，解决了现有技术中的电压力锅的用户使用体验差的问题。此外，由于当转动部40转动至锁定位置时，推顶部50不再向所述限压阀30施加外力，因此上述结构能够保证限压阀30在烹饪阶段时正常工作，实现高压烹煮的目的。According to the technical solution of the first embodiment, the electric pressure cooker includes a push top portion 50 pivotally arranged on the lining 22, and the push top portion 50 is driven by the rotating portion 40. When the rotating portion 40 is in the unlocking position, and in the process of the rotating portion 40 rotating from the unlocking position to the middle position, the push top portion 50 cooperates with the pressure limiting valve 30 to connect the gas in the pot body 10 with the outside atmosphere. When the rotating portion 40 rotates from the middle position to the locking position, the push top portion 50 moves away from the pressure limiting valve 30. When the rotating portion 40 rotates to the locking position, the push top portion 50 no longer applies force to the pressure limiting valve 30. In the above structure, since the push top portion 50 keeps pushing the pressure limiting valve 30 during the process of the rotating portion 40 rotating from the unlocked position to the middle position, the hot air in the pot can be discharged to the outside as much as possible, thereby reducing the pressure in the pot, and further reducing the friction between the pot teeth and the cover teeth when closing the lid, or avoiding the friction between the pot teeth and the cover teeth, improving the smoothness of opening and closing the pot lid 20, improving the user experience, and solving the problem of poor user experience of the electric pressure cooker in the prior art. In addition, since the push top portion 50 no longer applies external force to the pressure limiting valve 30 when the rotating portion 40 rotates to the locked position, the above structure can ensure that the pressure limiting valve 30 works normally during the cooking stage, and achieve the purpose of high-pressure cooking.
需要说明的是，上述解锁位置指的是锅牙与盖牙分离时的位置，即在锅体的径向方向上锅牙与盖牙完全错位时的位置，此时锅盖20能够与锅体10分离。上述锁定位置指的是锅牙与盖牙扣合时的位置，此时锅盖20与锅体10不能分离。上述中间位置指的是锅牙没有完全与盖牙分离时的位置，即在锅体的径向方向上锅牙与盖牙有一定错位时的位置，此时锅盖20也无法与锅体10分离。It should be noted that the unlocked position refers to the position when the pot teeth and the cover teeth are separated, that is, the position when the pot teeth and the cover teeth are completely misaligned in the radial direction of the pot body, and the pot cover 20 can be separated from the pot body 10 at this time. The locked position refers to the position when the pot teeth and the cover teeth are buckled, and the pot cover 20 cannot be separated from the pot body 10 at this time. The intermediate position refers to the position when the pot teeth are not completely separated from the cover teeth, that is, the position when the pot teeth and the cover teeth are misaligned to a certain extent in the radial direction of the pot body, and the pot cover 20 cannot be separated from the pot body 10 at this time.
还需要说明的是，在高压烹饪时，限压阀30与推顶部50之间相分离。当锅体10内的压力达到预定压力时发出触发信号，电磁阀的阀杆61响应于上述触发信号推顶限压阀30，以使限压阀30连通锅体10内的气体与外界大气。当然，本领域技术人员应当知道，推顶限压阀30的结构不限于上述电磁阀的阀杆61，只要能将限压阀30推顶至预定位置即可。It should also be noted that during high pressure cooking, the pressure limiting valve 30 is separated from the pushing portion 50. When the pressure in the pot body 10 reaches a predetermined pressure, a trigger signal is sent, and the valve stem 61 of the solenoid valve pushes the pressure limiting valve 30 in response to the trigger signal, so that the pressure limiting valve 30 connects the gas in the pot body 10 with the outside atmosphere. Of course, those skilled in the art should know that the structure of the pushing pressure limiting valve 30 is not limited to the valve stem 61 of the solenoid valve, as long as the pressure limiting valve 30 can be pushed to a predetermined position.
如图1至图7所示，在实施例一中，转动部40上设置有驱动柱41，推顶部50上设置有与驱动柱41配合的导向孔51，导向孔51包括第一导向段511以及第二导向段512。如图5所示，当转动部40位于解锁位置与中间位置之间时，驱动柱41位于第一导向段511内，当转动部40位于中间位置时，驱动柱41位于第一导向段511与第二导向段512的连接处。如图7所示，当转动部40位于锁定位置与中间位置之间时，驱动柱41位于第二导向段512内，其中，当驱动柱41在第一导向段511内向第二导向段512的导向方向滑动时，推顶部50处于静止状态，当驱动柱41由第二导向段512的靠近第一导向段511的一端滑动至第二导向段512的另一端时，推顶部50向远离限压阀30的方向移动，当驱动柱41在第二导向段512内向第一导向段511的方向滑动时，推顶部50处于静止状态，当驱动柱41由第一导向段511的靠近第二导向段512的一端滑动至第一导向段511的另一端时，推顶部50向靠近限压阀30的方向移动。上述结构简单，易于实现。As shown in FIGS. 1 to 7 , in the first embodiment, a driving column 41 is provided on the rotating part 40, and a guide hole 51 cooperating with the driving column 41 is provided on the pushing part 50, and the guide hole 51 includes a first guide section 511 and a second guide section 512. As shown in FIG. 5 , when the rotating part 40 is located between the unlocking position and the middle position, the driving column 41 is located in the first guide section 511, and when the rotating part 40 is located in the middle position, the driving column 41 is located at the connection between the first guide section 511 and the second guide section 512. As shown in FIG7 , when the rotating portion 40 is located between the locking position and the intermediate position, the driving column 41 is located in the second guide section 512, wherein when the driving column 41 slides in the first guide section 511 in the guiding direction of the second guide section 512, the pushing portion 50 is in a stationary state, and when the driving column 41 slides from one end of the second guide section 512 close to the first guide section 511 to the other end of the second guide section 512, the pushing portion 50 moves in a direction away from the pressure limiting valve 30, and when the driving column 41 slides in the second guide section 512 in the direction of the first guide section 511, the pushing portion 50 is in a stationary state, and when the driving column 41 slides from one end of the first guide section 511 close to the second guide section 512 to the other end of the first guide section 511, the pushing portion 50 moves in a direction close to the pressure limiting valve 30. The above structure is simple and easy to implement.
如图5和图7所示，在实施例一中，当驱动柱41位于第一导向段511内时，与驱动柱41配合的第一导向段511的孔壁与驱动柱41的移动轨迹重合，与驱动柱41配合的第二导向段512的孔壁与驱动柱41的移动轨迹相干涉。当驱动柱41位于第二导向段512内时，与驱动柱41配合的第二导向段512的孔壁与驱动柱41的移动轨迹重合，与驱动柱41配合的第一导向段511的孔壁与驱动柱41的移动轨迹相干涉。上述结构简单，易于实现。As shown in FIG. 5 and FIG. 7 , in the first embodiment, when the driving column 41 is located in the first guide section 511, the hole wall of the first guide section 511 matched with the driving column 41 coincides with the moving track of the driving column 41, and the hole wall of the second guide section 512 matched with the driving column 41 interferes with the moving track of the driving column 41. When the driving column 41 is located in the second guide section 512, the hole wall of the second guide section 512 matched with the driving column 41 coincides with the moving track of the driving column 41, and the hole wall of the first guide section 511 matched with the driving column 41 interferes with the moving track of the driving column 41. The above structure is simple and easy to implement.
具体地，如图5和图7所示，当驱动柱41位于第一导向段511内时，与驱动柱41配合的第一导向段511的孔壁与驱动柱41的移动轨迹重合，由于与驱动柱41配合的第二导向段512的孔壁与驱动柱41的移动轨迹相干涉，因此，当驱动柱41由中间位置向锁定位置移动时，驱动柱41的外侧壁会向与其配合的第二导向段512的孔壁施加外力，推顶推顶部50，使得推顶部50向远离限压阀30的方向移动。同理，当驱动柱41位于第二导向段512内时，与驱动柱41配合的第二导向段512的孔壁与驱动柱41的移动轨迹重合，由于与驱动柱41配合的第一导向段511的孔壁与驱动柱41的移动轨迹相干涉，因此，当驱动柱41由中间位置向解锁位置移动时，驱动柱41的外侧壁会向与其配合的第一导向段511的孔壁施加外力，推顶推顶部50，使得推顶部50向靠近限压阀30的方向移动。Specifically, as shown in Figures 5 and 7, when the driving column 41 is located in the first guide section 511, the hole wall of the first guide section 511 that cooperates with the driving column 41 coincides with the moving trajectory of the driving column 41. Since the hole wall of the second guide section 512 that cooperates with the driving column 41 interferes with the moving trajectory of the driving column 41, when the driving column 41 moves from the middle position to the locking position, the outer wall of the driving column 41 will apply an external force to the hole wall of the second guide section 512 that cooperates with it, pushing the pushing top part 50, so that the pushing top part 50 moves in the direction away from the pressure limiting valve 30. Similarly, when the driving column 41 is located in the second guide section 512, the hole wall of the second guide section 512 matched with the driving column 41 coincides with the moving trajectory of the driving column 41. Since the hole wall of the first guide section 511 matched with the driving column 41 interferes with the moving trajectory of the driving column 41, when the driving column 41 moves from the middle position to the unlocking position, the outer wall of the driving column 41 applies an external force to the hole wall of the first guide section 511 matched with it, pushing the pushing top portion 50, so that the pushing top portion 50 moves toward the direction close to the pressure limiting valve 30.
如图2至图4和图6所示，在实施例一中，电压力锅还包括电磁阀60。电磁阀60设置在内衬22上，电磁阀60包括阀杆61，推顶部50通过阀杆61推动限压阀30。具体地，当转动部40位于解锁位置时，以及转动部40由解锁位置转动至中间位置的过程中，推顶部50推顶电磁阀60的阀杆61，阀杆61的端部推动限压阀30，使得限压阀30远离排气管道，从而达到在合盖过程中，锅体10内的气体与外界大气连通，减少锅体内压力的目的。当转动部40由中间位置向锁定位置转动时，推顶部50远离阀杆61，阀杆61在回复力的作用下远离限压阀30。限压阀30由于失去了外力的抵顶，其在重力作用下回到封堵排气管的排气通道的位置上，从而达到限压阀30在烹饪阶段时能够正常工作的目的。As shown in FIGS. 2 to 4 and 6 , in the first embodiment, the electric pressure cooker further comprises an electromagnetic valve 60. The electromagnetic valve 60 is arranged on the inner lining 22, and the electromagnetic valve 60 comprises a valve stem 61. The push-up portion 50 pushes the pressure limiting valve 30 through the valve stem 61. Specifically, when the rotating portion 40 is located at the unlocking position, and in the process of the rotating portion 40 rotating from the unlocking position to the middle position, the push-up portion 50 pushes the valve stem 61 of the electromagnetic valve 60, and the end of the valve stem 61 pushes the pressure limiting valve 30, so that the pressure limiting valve 30 is away from the exhaust pipe, thereby achieving the purpose of connecting the gas in the pot body 10 with the outside atmosphere during the lid closing process and reducing the pressure in the pot body. When the rotating portion 40 rotates from the middle position to the locking position, the push-up portion 50 is away from the valve stem 61, and the valve stem 61 is away from the pressure limiting valve 30 under the action of the restoring force. Since the pressure limiting valve 30 loses the push-up of the external force, it returns to the position of blocking the exhaust passage of the exhaust pipe under the action of gravity, thereby achieving the purpose of the pressure limiting valve 30 being able to work normally during the cooking stage.
如图2至图4和图6所示，在实施例一中，阀杆61外套设有弹簧。As shown in FIG. 2 to FIG. 4 and FIG. 6 , in the first embodiment, a spring is disposed on the outer sleeve of the valve stem 61 .
如图5和图7所示，在实施例一中，第二导向段512包括配合孔段5121以及避让孔段5122，当转动部40位于解锁位置与中间位置之间时，避让孔段5122位于驱动柱41的移动轨迹的内侧。具体地，当驱动柱41位于第一导向段511时，推顶部50抵顶阀杆61，阀杆61上的弹簧压缩，存储一定的弹性势能。当驱动柱41开始进入第二导向段512内时，由于避让孔段5122位于驱动柱41的移动轨迹的内侧，因此在弹簧的弹性回复力的作用下，推顶部50向远离限压阀30的方向转动，驱动柱41会进入推顶部50的避让孔段5122内。进入避让孔段5122内的驱动柱41在避让孔段5122的孔壁的限位下保持在避让孔段5122内。上述结构简单，使得合盖顺畅，提高用户体验。As shown in FIG. 5 and FIG. 7 , in the first embodiment, the second guide section 512 includes a matching hole section 5121 and an avoidance hole section 5122. When the rotating part 40 is located between the unlocking position and the middle position, the avoidance hole section 5122 is located inside the moving track of the driving column 41. Specifically, when the driving column 41 is located in the first guide section 511, the push part 50 pushes against the valve stem 61, and the spring on the valve stem 61 is compressed to store a certain elastic potential energy. When the driving column 41 begins to enter the second guide section 512, since the avoidance hole section 5122 is located inside the moving track of the driving column 41, the push part 50 rotates away from the pressure limiting valve 30 under the action of the elastic restoring force of the spring, and the driving column 41 enters the avoidance hole section 5122 of the push part 50. The driving column 41 entering the avoidance hole section 5122 is kept in the avoidance hole section 5122 under the limitation of the hole wall of the avoidance hole section 5122. The above structure is simple, which makes the cover close smoothly and improves the user experience.
当然，本领域技术人员应当知道，推顶部50向远离限压阀30的方向转动不一定要依靠套在阀杆61上弹簧的弹力，还有可能是在推顶部50的枢转轴上设置扭簧，当转动部40位于解锁位置时，或者位于解锁位置与中间位置之间时，扭簧存储势能。当转动部40由中间位置向锁定位置移动时，推顶部50在扭簧的作用下向远离限压阀30的方向移动。当转动部40位于锁定位置时，扭簧处于自由状态。Of course, those skilled in the art should know that the push part 50 does not necessarily rotate in the direction away from the pressure limiting valve 30 by relying on the elastic force of the spring sleeved on the valve stem 61. It is also possible that a torsion spring is arranged on the pivot axis of the push part 50. When the rotating part 40 is in the unlocked position, or between the unlocked position and the intermediate position, the torsion spring stores potential energy. When the rotating part 40 moves from the intermediate position to the locked position, the push part 50 moves in the direction away from the pressure limiting valve 30 under the action of the torsion spring. When the rotating part 40 is in the locked position, the torsion spring is in a free state.
如图5和图7所示，在实施例一中，第一导向段511的宽度与第二导向段512的配合孔段5121的宽度均等于驱动柱41的直径。上述结构具有导向作用，能够进一步使得合盖顺畅，提高用户体验。当然，本领域技术人员应当知晓，驱动柱41与第一导向段511的内壁和第二导向段512的内壁之间均为间隙配合，以使驱动柱41能够顺利地在第一导向段511与第二导向段512内滑动。As shown in FIG. 5 and FIG. 7 , in the first embodiment, the width of the first guide section 511 and the width of the matching hole section 5121 of the second guide section 512 are both equal to the diameter of the drive column 41. The above structure has a guiding effect, which can further make the cover close smoothly and improve the user experience. Of course, those skilled in the art should know that the drive column 41 is clearance-fitted with the inner wall of the first guide section 511 and the inner wall of the second guide section 512, so that the drive column 41 can slide smoothly in the first guide section 511 and the second guide section 512.
如图5所示，在实施例一中，当转动部40转动至解锁位置时，驱动柱41的旋转中心A与驱动柱41的轴线的连线为第一连线a1，当转动部40转动至中间位置时，旋转中心A与驱动柱41的轴线的连线为第二连线a2，第一连线a1与第二连线a2之间的角度在10°至35°之间。上述结构使得解锁位置至中间位置之间的距离足够长，即合盖时推顶限压阀30的时间足够长，因此上述结构进一步使得锅内的热气能够尽量多的排至外界，减小了锅内的压力，提高了锅盖开合的顺畅性。As shown in FIG5 , in the first embodiment, when the rotating part 40 rotates to the unlocking position, the line connecting the rotation center A of the driving column 41 and the axis of the driving column 41 is the first line a1 , and when the rotating part 40 rotates to the middle position, the line connecting the rotation center A and the axis of the driving column 41 is the second line a2 , and the angle between the first line a1 and the second line a2 is between 10° and 35°. The above structure makes the distance between the unlocking position and the middle position long enough, that is, the time for pushing the pressure limiting valve 30 when closing the lid is long enough, so the above structure further enables the hot air in the pot to be discharged to the outside as much as possible, reduces the pressure in the pot, and improves the smoothness of opening and closing the lid.
如图2和图3所示，在实施例一中，内衬22上设置有内衬轴221，推顶部50为顶杆，顶杆上设置有与内衬轴221配合的安装孔52，顶杆通过内衬轴221可枢转地设置在内衬22上。上述结构简单，易于实现。As shown in Fig. 2 and Fig. 3, in the first embodiment, the lining 22 is provided with a lining shaft 221, the push part 50 is a push rod, the push rod is provided with a mounting hole 52 that matches the lining shaft 221, and the push rod is pivotally arranged on the lining 22 through the lining shaft 221. The above structure is simple and easy to implement.
如图2、图3、图5和图7所示，在实施例一中，顶杆上设置有用以推顶限压阀30的推顶凸起53，推顶凸起53与导向孔51设置在安装孔52的两侧。上述结构简单，易于实现。As shown in Figures 2, 3, 5 and 7, in the first embodiment, the push rod is provided with a push-up protrusion 53 for pushing up the pressure limiting valve 30, and the push-up protrusion 53 and the guide hole 51 are arranged on both sides of the mounting hole 52. The above structure is simple and easy to implement.
如图2至图4、图6所示，在实施例一中，转动部40为转杆，转杆的一端可枢转地设置在内衬22上，转杆的另一端与锁盖21上的销轴配合，转杆位于推顶部50的上方，驱动柱41设置在转杆的下部并向下延伸。上述结构简单，能够充分利用空间，使得电压力锅的结构更加紧凑。As shown in Fig. 2 to Fig. 4 and Fig. 6, in the first embodiment, the rotating part 40 is a rotating rod, one end of which is pivotally arranged on the inner lining 22, and the other end of which cooperates with the pin on the lock cover 21. The rotating rod is located above the push-up part 50, and the driving column 41 is arranged at the lower part of the rotating rod and extends downward. The above structure is simple, can make full use of space, and makes the structure of the electric pressure cooker more compact.
如图8至图10所示，实施例二的电压力锅与实施例一的区别在于导向孔51的具体形状。具体地，在实施例二中，导向孔51包括第一导向段511、第二导向段512以及设置在第一导向段511与第二导向段512之间的中间过渡段513。其中第一导向段511与第二导向段512相对于中间过渡段513对称设置。As shown in FIGS. 8 to 10 , the difference between the electric pressure cooker of the second embodiment and the first embodiment lies in the specific shape of the guide hole 51. Specifically, in the second embodiment, the guide hole 51 includes a first guide section 511, a second guide section 512, and an intermediate transition section 513 disposed between the first guide section 511 and the second guide section 512. The first guide section 511 and the second guide section 512 are symmetrically disposed relative to the intermediate transition section 513.
优选地，在实施例二中，第一导向段511与第二导向段512的长度相等。Preferably, in the second embodiment, the lengths of the first guide section 511 and the second guide section 512 are equal.
如图9和图10所示，在实施例二中，当转动部40转动至中间位置时，驱动柱41的旋转中心A与驱动柱41的轴线的连线为第二连线a2，当转动部40转动至锁定位置时，旋转中心A与驱动柱41的连线为第三连线a3，第二连线a2与第三连线a3之间的角度在5°至35°之间。上述结构使得解锁位置至中间位置之间的距离足够长，即合盖时推顶限压阀30的时间足够长，因此上述结构进一步使得锅内的热气能够尽量多的排至外界，减小了锅内的压力，提高了锅盖开合的顺畅性。As shown in Fig. 9 and Fig. 10, in the second embodiment, when the rotating part 40 rotates to the middle position, the line connecting the rotation center A of the driving column 41 and the axis of the driving column 41 is the second linea2 , and when the rotating part 40 rotates to the locking position, the line connecting the rotation center A and the driving column 41 is the third linea3 , and the angle between the second linea2 and the third linea3 is between 5° and 35°. The above structure makes the distance between the unlocking position and the middle position long enough, that is, the time for pushing the pressure limiting valve 30 when closing the lid is long enough, so the above structure further enables the hot air in the pot to be discharged to the outside as much as possible, reduces the pressure in the pot, and improves the smoothness of opening and closing the lid.
