Detailed Description

The following detailed description of the embodiments of the present utility model is provided with reference to the accompanying drawings, so that the technical scheme of the present utility model can be understood and mastered more easily. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

The embodiment provides an anti-overflow pressure cooker cover which is matched with a cooker body of a pressure cooker. As shown in fig. 1 to 4, the pot cover comprises a cover body 100, an overflow preventing cover 200 is arranged on the lower surface of the cover body 100, an air outlet hole 220 and a backflow hole 210 are arranged on the overflow preventing cover 200, the width of the backflow hole 210 is larger than that of the air outlet hole 220, a cover pad 230 is arranged at the backflow hole 210 of the overflow preventing cover 200 to block the backflow hole 210, and the cover pad 230 opens the backflow hole 210 when the condensed water in the overflow preventing cover 200 reaches a specific amount. Steam enters the anti-overflow cover 200 from the air outlet 220, and the smaller air outlet 220 is beneficial to blocking food from entering the anti-overflow cover 200, so that the exhaust pipe 400 is prevented from being blocked by the food. The larger return holes 210 facilitate the return of condensate within the anti-overflow housing 200 to the pan. At the initial stage of cooking, the cover pad 230 blocks the backflow hole 210, so that steam and food materials are prevented from entering the anti-overflow cover 200 from the backflow hole 210, and because the width of the air outlet hole 220 is smaller, condensed water in the anti-overflow cover 200 is difficult to flow back to the pot body from the air outlet hole 220, bubbles can be broken, and the risk of overflowing is reduced. When the condensed water in the anti-overflow cover 200 is accumulated to a certain amount, the cover pad 230 is deformed under the gravity action of the condensed water, so that the backflow hole 210 is opened, the condensed water in the anti-overflow cover 200 flows back into the pot body, and the overflow of the condensed water in the anti-overflow cover 200 from the exhaust pipe 400 or the unsmooth exhaust of the exhaust pipe 400 is avoided.

As shown in fig. 5-6, the air outlet 220 includes a circular hole and an elongated hole. Under the condition that the diameter of the round hole and the width of the strip hole are smaller, the food material can be prevented from passing through. In other alternative embodiments, the outlet holes 220 may be circular holes or elongated holes or other polygonal holes alone.

As shown in fig. 4, the backflow hole 210 is located at a side portion of the bottom wall of the overflow preventing cap 200, and a middle portion of the bottom wall of the overflow preventing cap 200 is protruded upward with respect to the side portion. This facilitates the water in the anti-overflow cover 200 to be collected to the side, and facilitates the water to be accumulated at the return hole 210 to open the return hole 210. The partial air outlet 220 is located in the middle of the bottom wall of the anti-overflow cover 200 or extends towards the middle of the anti-overflow cover 200, and the middle of the bottom wall of the higher anti-overflow cover 200 can avoid water accumulation in the middle, so that steam can smoothly pass through the air outlet 220.

As shown in fig. 4-6, the bottom wall of the anti-overflow cover 200 has a recess 240, and the return hole 210 is located in the recess 240. This can better enable water within the spill-resistant enclosure 200 to flow toward the return aperture 210. As shown in fig. 5-6, the backflow hole 210 is in a fan-ring shape, the concave-down part 240 is in a circular shape, the single concave-down part 240 is provided with three backflow holes 210, the circular concave-down part 240 is matched with the fan-ring-shaped backflow hole 210, so that a larger backflow hole 210 is formed, and the area of the backflow hole 210 is larger than that of the air outlet hole 220. In other alternative embodiments, the return aperture 210 may be circular or polygonal.

As shown in fig. 4 to 6, the cover gasket 230 has a fixing post 231, and the bottom wall of the overflow preventing cover 200 has a fixing hole 250, and the fixing post 231 is inserted and fixed in the fixing hole 250. When the spill guard 200 is deformed, the outer end moves downward to open the return hole 210.

As shown in fig. 4 and 6, the middle part of the bottom wall of the anti-overflow cover 200 is provided with a flexible fastener 300, the lid comprises an exhaust pipe 400 and a fastener 500, the fastener 500 is in threaded connection with the exhaust pipe 400, the exhaust pipe 400 and the fastener 500 are clamped and fixed on the lid 100 in a matching manner, and the flexible fastener 300 is in clamping fit with the fastener 500. Thus, the anti-overflow cap 200 can be quickly detached from the fastener 500, and the anti-overflow cap is convenient to disassemble, assemble and clean. The outer side wall of the flexible buckling piece 300 is provided with a mounting groove 310, the bottom wall of the anti-overflow cover 200 is provided with a mounting hole, the flexible buckling piece 300 passes through the mounting hole, the edge of the mounting hole is embedded into the mounting groove 310, the width of the upper wall of the mounting groove 310 is larger than that of the lower wall, when the flexible buckling piece 300 is pulled down conveniently, the upper wall of the mounting groove 310 generates more stable downward pressure on the anti-overflow cover 200, and the anti-overflow cover 200 is detached along with the flexible buckling piece 300. The portion of the flexible fastener 300 located below the spill guard 200 has an operating slot 320 to facilitate manual application of force. The flexible fastener 300 has a fixing groove 330 with an opening facing upward, and the lower end of the fastener 500 is inserted into the fixing groove 330 and is caught in the fixing groove 330. In other alternative embodiments, the flexible fastener 300 may be secured to the lower end of the exhaust pipe 400.

As shown in fig. 4, the fastening member 500 has a lateral air intake hole 510, the air discharge pipe 400 has a vertical air discharge hole 410, and the air intake hole 510 communicates with the air discharge hole 410. This increases the turning of the steam flow path, prevents steam from being ejected from the exhaust pipe 400 at an excessively high speed, improves the safety of the pressure cooker in use, and facilitates the condensation of steam in the anti-overflow cover 200. The risk of food material passing up through the air outlet holes 220 blocking the lateral air inlet holes 510 is reduced.

As shown in fig. 4, the minimum outer diameter of the sidewall of the spill guard 200 is greater than 2 times the maximum outer diameter of the exhaust pipe 400. In this embodiment, the minimum outer diameter of the side wall of the anti-overflow cover 200 is 3 times greater than the maximum outer diameter of the exhaust pipe 400, and the side wall of the anti-overflow cover 200 abuts against the cover 100 to form a cavity with a larger space, so as to slow down the exhaust speed and make the steam pressure in the pot body more balanced.
