Problems solved by technology
However, the exhaust holes are very small, and the diameter generally does not exceed 3mm. During the actual exhaust and pressure relief process, the miscellaneous debris in the pot is easily discharged with the air flow, the exhaust holes are easily blocked, and the pressure regulation effect is poor. It may lead to the explosion of the pressure cooker, and there are certain safety hazards in use
Moreover, when the pressure-sensing hammer releases pressure, it must be impacted by the pressure-releasing air flow, and the pressure-adjusting action will definitely interfere with the pressure-sensing effect, making the pressure detection inaccurate, and the overall pressure control effect of the pressure cooker cannot be accurately realized.

Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings.
[0023] according to figure 1 and figure 2 As shown, the pressure control device for a pressure cooker of the present invention includes a pressure sensing mechanism and a pressure regulating mechanism. Among them, the pressure sensing mechanism includes a sealing sleeve 2 fixed on the pressure cooker cover 1 and having a connecting hole, a pressure sensing hammer 3 corresponding to the position of the connecting hole on the sealing sleeve 2, and a pressure sensing rod 4 cooperating with the connecting hole of the sealing sleeve 2. . A sealing gasket 13 and a nut 14 are arranged between the sealing sleeve 2 and the pressure cooker cover 1, and the pressure sensing rod 4 is integrally connected with the pressure sensing hammer 3. The dynamic pressure hammer 3 slides along the sealing sleeve 2 connecting hole. Because the pressure-sensing rod 4 is only subjected to t...

Abstract
The invention discloses a pressure-control device for pressure cooker, comprising a pressure-sensitive device and pressure-regulation device, and the pressure-sensitive device is equipped with a seal housing fixed on pot cover and equipped with a connection pore and a pressure-sensitive hammer relative to said connection pore, the invention is characterized in that: said pressure-sensitive hammer is equipped with a pressure-sensitive pole which can slide along connection pore and seal air in pot under stationary and moving condition, said pressure-regulation device comprises air-out axis support installed in pan cover, air-out axis on air-out axis support and air-out pivoted housing packing air on air-out axis and rotating and sliding on air-out axis, the pressure condition in pot can be reflected by sliding condition of pressure-sensitive hammer by pressure-sensitive pole; and pressure-regulation device will actively guide air in pot according to pressure-regulation signal to regulate pressure in time. The invention is characterized by sensitive pressure sensing, accurate pressure regulation, high efficiency and safe and reliable usage.
Description
technical field [0001] The invention relates to a pressure control device for a pressure cooker. Background technique [0002] In the prior art, common pressure control devices for pressure cookers mostly use a single pressure-sensing hammer type pressure limiting valve mechanism. The mechanism completes the pressure control effect of the pressure cooker through the cooperation of the pressure-sensing action and the pressure-regulating action. Both the pressure-sensing action and the pressure-regulating action are completed by the pressure-sensing hammer, and the pressure-sensing effect is mainly determined by the pressure-bearing surface of the pressure-sensing hammer. When the pressure in the pot is large enough to lift the pressure-sensitive hammer into the air, since there is a large gap between the hammer needle and the sealing sleeve, and there is a stepped structure or a cone structure on the upper part of the hammer needle, the pressure-sensitive hammer is actually u...
