[0026] Example

[0027] Main scheme :

[0028] Adjustable pressure micro-pressure cooker, such as Figures 1-6As shown, the device includes a pot body 10 and a lid 20 that fits onto the pot body 10. The lid 20 is characterized by a mounting column 201 with a mounting cavity in the middle. The mounting cavity is divided into an upper cavity 2012 and a lower cavity 2013 by a partition 2014. An adjustment knob 202 is threaded onto the upper cavity 2012, and a spring 205 is located below the adjustment knob 202. A valve stem 203 is vertically slidably sealed on the partition 2014. The top of the valve stem 203 abuts against the spring 205, and a valve core 204 is located at the bottom of the valve stem 203. The valve core 204 is located inside the lower cavity 2013, and an annular abutment platform 2015 is provided on the lower side of the lower cavity 2013 for the valve core 204 to abut against and form a seal. An exhaust channel 2011 extending to the side wall of the lower cavity 2013 is provided inside the mounting column 201. This design places the exhaust channel 2011 inside the mounting column 201 on the cover 20, and creates a cavity in the middle of the mounting column 201 to house the spring spring 205. A control valve within the cavity automatically controls steam discharge, preventing contact between the steam and the spring spring 205 during use. This avoids performance degradation or rusting of the spring spring 205 due to steam. In actual production, the partition 2014 can be configured with a threaded connection for easy installation of components.

[0038] like Figure 1 and 2 As shown, the pot body 10 has two opposing lower pot ears 100, and the lid 20 has two opposing upper pot ears 200. A limiting locking structure is provided between the upper pot ears 200 and the lower pot ears 100. The locking structure is used to lock the lid 20 and the pot body 10 to ensure a seal at the contact point between them.

[0039] Specifically, the limiting and locking structure includes an irregularly shaped through hole 1001 provided on the lower pot ear 100 and a rotating column 2001 rotatably provided on the upper pot ear 200. The bottom of the rotating column 2001 is provided with a horizontally extending hook 2002. The rotating column 2001 extends into the through hole 1001 and the hook 2002 is located below the lower pot ear 100. When the rotating column 2001 is rotated so that the top of the hook 2002 is against the bottom surface of the lower pot ear 100, the cover 20 is locked. When the rotating column 2001 is rotated so that the hook 2002 is located at the through hole 1001, the cover 20 is unlocked.

[0040] Preferably, when the lid 20 is placed on the pot body 10, the upper pot handle 200 and the lower pot handle 100 have a gap that allows fingers to be inserted. This gap is used to facilitate the removal of the lid 20 by inserting fingers into the gap after unlocking.
