Abstract
The utility model relates to a lid-opening safety device for a pressure-cooker. The utility model, which is composed of a cooker lid (1), a cooker body (2), a sealing rubber ring (3), an upper handle (9) and a lower handle (10), is mainly characterized in that the inside of the upper handle is provided with a lid-opening push rod mechanism which is formed by the connection of a pushing block (4), a screw (5), a push rod piece (6), a button (7) and a spring (8); the lower handle is provided with a bayonet limiting structure for a convex step. When the lid is opened, the lid-opening push rod mechanism must be pushed to act, discharge gas and relieve pressure, which achieves the purpose that the lid is safely opened. The utility model has simple structure, and the structure of the pressure cooker and the manufacturing technique do not need to be changed.
Description
The utility model is a kind of pressure cooker safety device of uncapping.
Existing pressure cooker is made up of pot body, pot cover, pressure limiting valve, O-ring seal, upper handle, lower handle, the safety device of all not uncapping.Behind cooking food, owing to have steam in the pot, must not uncap at once, after can only parking a period of time or drenching but, treat just can uncap after pot inner vapor pressure disappears with cold water.Remained steam in pot, the user do not note and when uncapping, and takes place easily that steam is burnt or security incident.
The purpose of this utility model is a kind of new pressure cooker of invention safety device of uncapping, and when uncapping, needs to promote a push button, by the transfer bar mechanism action of uncapping, uncaps after making pot inner pressure steam drain step-down, reaches safety and uncaps.
Realize that the utility model scheme is that a transfer bar mechanism of uncapping that is connected into by jacking block, putting film, push button, hold-down screw, back-moving spring is set in upper handle, the bayonet socket position limiting structure that the boss rank are set on corresponding lower handle is formed the safety device of uncapping.When pot cover screwed with the pot body, the upper handle putting film can not be uncapped by the spacing automatic fastening of lower handle boss bayonet socket.In the time of need uncapping, has only the upper handle of promotion push button, by the transfer bar mechanism action of uncapping, jacking block backs down the pressure release of certain distance gap to O-ring seal in the pressure cooker, putting film screws in the other direction from the spacing disengaging of bayonet socket on lower handle boss rank simultaneously, reaches the security purpose of uncapping.
Below in conjunction with an embodiment and accompanying drawing, illustrate the utility model pressure cooker safety device of uncapping.
Fig. 1 is the uncap installation diagram of safety device of pressure cooker.
Fig. 2 is the pressure cooker transfer bar mechanism installation diagram of uncapping in the upper handle of safety device of uncapping.
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is the B-B view of Fig. 2.
Fig. 5 is the uncap pot cover part drawing of safety device of pressure cooker.
The pressure cooker safety device of uncapping is made up of pot cover 1, pot body 2, O-ring seal 3, upper handle 9, lower handle 10 among Fig. 1, it is characterized in that being provided with jacking block 4, screw 5, putting film 6, push button 7, spring 8 and be connected into the transfer bar mechanism of uncapping in upper handle 9; Lower handle 10 corresponding upper handles 9 planes are provided with the bayonet socket position limiting structure of boss rank S.Last lower handle 9,10 is fixed on pot cover 1 and the pot body 2 by screw respectively.
The transfer bar mechanism jacking block 4 of uncapping among Fig. 2, pass pot cover 1 square tube hole (see figure 5), one end face is near O-ring seal, internal thread has been attacked in the other end, behind the screw 5 cover upper springs 8, pass the putting film 6 of upper handle 9 preformed through holes and band push button 7, ellipse garden through hole (see figure 4) screws in jacking block 4 band internal threads one end, when push button 7 advances along the direction of arrow, by the transfer bar mechanism action of uncapping, jacking block 4 is released, (shown in the dotted line) its end face then backs down O-ring seal in the pressure cooker gap of certain distance, make steam obtain pressure release, screw 5 plays connection and the transfer bar mechanism of fixedly uncapping acts on 8 reset responses of spring in upper handle 9.
Push button 7 among Fig. 3 in the preformed recess, can and automatically reset to the promotion of pot cover direction on upper handle 9.
Ellipse garden through hole is arranged on the putting film 6 among Fig. 4, and in order to by screw 5 with satisfy the transfer bar mechanism of uncapping and move, putting film 6 and push button 7 press and close or be injection molded into one and all can.
Hole, two gardens is pot cover 1 and upper handle screw attachment hole among Fig. 5, and square hole is jacking block 4 through holes.
From the foregoing description, when pot cover 1 screws with pot body 2, lower handle 10 faces are provided with boss rank S position limiting structure makes putting film 6 eject the arrival spacing position of bayonet socket, boss rank, back gradually along the boss cambered surface, because spring 8 reset responses, putting film 6 is closed by the spacing bales catch of lower handle boss rank bayonet socket, can not uncap.When need are uncapped, must be with push button 7 to pot cover 1 direction push-tight, by the transfer bar mechanism action of uncapping, putting film 6 is released jacking block 4 to pot cover 1 direction, is backed down the pressure release of certain distance gap by the jacking block 4 end-acted O-ring seals 3 that make, and pressure reduction is eliminated; Simultaneously putting film 6 breaks away from lower handles 10 to be provided with boss rank bayonet socket spacing, screws in the other direction this moment to reach the pressure cooker safety of uncapping.
This pressure cooker safety device of uncapping is simple in structure, only needs on the pressure cooker upper handle push-button type of installing transfer bar mechanism of uncapping, and need not change former pressure cooker structure and production technology.
