A kind of pressure cooker lid of quick pressure releasing
Technical field
The utility model relates to pressure cooker lid, and a kind of pressure cooker lid of quick pressure releasing particularly belongs to the improvement technology of pressure cooker.
Background technology
In order to guarantee the safety of pressure cooker, safety guard is set on pot cover all generally.When in the pressure cooker pot pressure being arranged, pot cover can not be opened.But, when culinary art finishes, quick-opening lid soon often because the pressure in the pot does not reduce.In order to address this problem, generally all be through pushing pressure limiting valve aside with hand, steam being discharged from blast pipe, in operating process, hand is scalded by the liquid of steam or ejection easily.
Summary of the invention
The purpose of the utility model is in order to address the above problem, and a kind of pressure cooker lid of quick pressure releasing simple in structure, safe and convenient to use is provided.
The technical scheme that realizes the utility model purpose is: a kind of pressure cooker lid of quick pressure releasing; Comprise connecting rod (1), push rod (2) and pressure limiting valve (3); Connecting rod (1) is arranged on the pot cover (9); One end of connecting rod (1) is provided with downward inclined-plane (11), the rear end of push rod (2) be provided with said connecting rod (1) on the inclined-plane that makes progress (21) that matches and move horizontally, inclined-plane (11), the front end of push rod (22) is oppositely arranged with pressure limiting valve (3).
Above-mentioned pressure limiting valve is the Weight type pressure limiting valve, and promptly pressure limiting valve comprises the weight (31) of salable blast pipe (4) and is covered on the outer pressure limiting valve bonnet of weight (31).
The top of above-mentioned connecting rod (1) is equipped with exhaust button (5);
Above-mentioned pot cover (9) is provided with projection (91), and the below of connecting rod (1) is provided with hollow convex column (12), is with reposition element (6) on the pot cover projection (91), and the projection (12) of connecting rod (1) is sleeved on the pot cover projection (91).
The front end (22) of above-mentioned push rod (2) passes said pressure limiting valve bonnet over against pressure limiting valve weight (31).
The front end (22) of above-mentioned push rod (2) is provided with reposition element (7).
The operation principle of the utility model is: when pot cover (9) is opened in the needs release; Push connecting rod (1) downwards with hand, the inclined-plane (11) on the connecting rod (1) contacts with the inclined-plane (21) of push rod (2), moves horizontally thereby promote push rod (2); When push rod (2) contact and promotion pressure limiting valve weight (31); Weight (31) and pressure limiting valve blast pipe (4) be when no longer sealing in this moment pressure limiting valve, thereby the steam in the pressure cooker is discharged from blast pipe (4), realizes fast pressure relief.When stopping to push connecting rod (1); The reposition element (6) that connecting rod (1) bottom is provided with promotes connecting rod (1) and resets; The reposition element (7) that push rod (2) front end is provided with promotes push rod (2) and resets, and weight (31) reason in the pressure limiting valve (3) is in the effect and blast pipe (4) sealing of gravity.The utility model also is applicable to the electric pressure cooking saucepan product, also belongs to the protection domain of the utility model.
The beneficial effect of the utility model is: utilize moving downward of connecting rod (1); Going up the inclined-plane (11) that is provided with through connecting rod (1) contacts with the inclined-plane (21) that push rod (2) is gone up setting; Push rod (2) is moved horizontally, promote to be arranged on the weight (31) that blast pipe (4) goes up in the pressure limiting valve (3) of sealing usefulness and realize fast pressure relief, can avoid the steam of blast pipe (4) ejection to scald human body; And it is simple in structure, easy to operate.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the specific embodiment of the utility model is further described.
Shown in Fig. 1-6, a kind of pressure cooker lid of quick pressure releasing comprises connecting rod 1, push rod 2 and pressure limiting valve 3, and said pressure limiting valve 3 is the Weight type pressure limiting valve, and promptly pressure limiting valve 3 comprises the weight 31 and the pressure limiting valve bonnet that is covered on outside the weight 31 of salable blast pipe 4; Pot cover 9 is provided with projection 91; The below of connecting rod 1 is provided with hollow convex column 12; Be with reposition element 6 on the pot cover projection 91, connecting rod projection 12 is sleeved on the pot cover projection 91, and an end of connecting rod 1 is provided with downward inclined-plane 11; One end of push rod 2 be provided with connecting rod on the inclined-plane that makes progress 21 that matches and move horizontally, inclined-plane 11, the front end 22 and the pressure limiting valve 3 of push rod are oppositely arranged.When push rod 2 horizontal movements, the front end 22 of push rod 2 passes the pressure limiting valve bonnet, promotes 31 motions of pressure limiting valve weight, thereby pressure limiting valve weight 31 is no longer sealed with the pressure limiting valve bonnet.In order to guarantee the sealing of push rod 2 and pressure limiting valve 3, pressure limiting valve bonnet lateral wall is provided with sealing ring, is with reposition element 7 on the push rod 2.
Have through hole 13 on the connecting rod 1, pot cover is provided with lead 92, guarantees that connecting rod 1 moves up and down on pot cover, and through hole has two in the present embodiment.For the ease of operation, on the hollow convex column 12 on the connecting rod 1 the bleeding parts are housed, functional unit is an exhaust button 5 in the present embodiment.
Above-mentioned reposition element 6 all adopts spring with reposition element 7.
When pot cover 9 is opened in the needs release, push exhaust button 5 downwards with hand, button 5 drivening rods 1 move downward; This moment, the inclined-plane 11 on the connecting rod 1 contacted with the inclined-plane 21 of push rod 4, thereby promotion push rod 2 moves horizontally, and push rod 2 contacts with weight 31 in the pressure limiting valve 3; When weight 31 and pressure limiting valve blast pipe 4 no longer seal; Thereby the steam in the pressure cooker is discharged from blast pipe 4, realize fast pressure relief, like Fig. 1, Fig. 2, shown in Figure 3.When stopping pressing keys 5; The reposition element 6 that connecting rod 1 bottom is provided with promotes connecting rod 1 and resets, and the reposition element 7 promotion push rods 2 that are sleeved on the push rod 2 reset, and weight 31 reasons in the pressure limiting valve 3 are in the effect resile of gravity; With blast pipe 4 sealings, like Fig. 4, Fig. 5, shown in Figure 6.
The utility model can be widely used on various pressure cookers and the electric pressure cooking saucepan equal pressure culinary products.
