Abstract

The utility model relates to a convenient safety pressure cooker which is the improvement of a pressure cooker. A cooker body is provided with a swivel base. The center of a cooker lid is connected with a rotating pole. One end of a lid handle is connected with the swivel base, and the lid handle is connected with the rotating pole; therefore, the cooker lid not only can carry out self-rotation, but also can be connected to the cooker body to be turned over up and down. Meanwhile, the lid handle is provided with a hole and the hole is matched with a float valve connected to the cooker lid to play a role of safety opening and closing.

Description

Convenient and safe pressure cooker

The family expenses pressure cooker is divided into usual pressure pot and electricity or combustion gas automatic pressure pot.Existing pressure cooker all is promptly the shape of working in coordination to be made in a pot cover lower edge and a pot body upper edge with embedded structure, utilizes sealing ring to close to rotate to an angle to reach behind the lid to close the effect that the jail seals.Existing pressure cooker must be lifted down lid when getting food from the pot body, very inconvenient.

The purpose of this utility model is to make pressure cooker have better security performance on original embedded structure basis, and folding with convenience.Pot cover needn't take off from the pot body when getting food, can not uncap when in the pot air pressure being arranged, and pressure can not raise when not in place when a pot cover and a pot body fasten.

The purpose of this utility model is to realize like this.On the pot body swivel base is arranged, be connected with at the pot cover center and revolve post, one end is connected in the lid handle on the swivel base and revolves post and connects together, make pot cover both can self be rotated, also can be connected on pot body and spin upside down, simultaneously, the lid handle has a hole and is connected in float-controlled valve on the pot cover and works in coordination and play the effect of safety opening-closing.

Explain detailedly with reference to the accompanying drawings below.Fig. 1 is embodiment of the present utility model, and Fig. 2 is that the overturn cover handle is got the diagram when eating.

Here illustrate that the usual pressure pot has only a pot body, two layers of outer pots even multilayer in the automatic pressure pot then is divided into.Pot body of the present utility model and existing pressure cooker are basic identical, and wherein the pot body of automatic pressure pot generally is meant outer pot body, on the promptly outer pot body swivel base is arranged, and sealing are interior pots.As Fig. 1, in pot body 10 upper left sides transposase 11 is arranged, transposase 11 has one or two axis hole, and lid handle 3 lower-left ends have two or a hole, and lid handle 3 lower-left ends can be incorporated in the transposase 11, and its corresponding aperture penetrates rotating shaft 2, like this, just lid handle 3 can be that rotate up and down in the axle center with rotating shaft 2.Pot cover 9 limited valves 8 parts such as grade, pot cover 9 centers are connected with revolves post 7, and the lid handle has and revolves hole 6, revolves post 7 and passes and revolve hole 6 and pot cover and lid handle are connected together, and pot cover 9 can be that the axle center rotates to revolve post 7.Porose 4 on the appropriate location of revolving 6 left sides, hole lids handle 3, when pressure cooker closed the jail sealing fully, the pot cover place under the hole 4 was connected with float-controlled valve 5, and float-controlled valve can fluctuate, but can not fall down.Floating go up and the sealing valve opening can further increase pressure when in the pot certain pressure being arranged, the upper end of float-controlled valve penetrates hole 4 can not rotate pot cover, that is to say not open when in the pot pressure being arranged pot; When pot inner pressure reduced, float-controlled valve fell naturally because of gravity, this moment rotatable pot cover and open it.Otherwise, when fastening is not in place, the hole misalignment float-controlled valve of lid handle, float-controlled valve tegmentum handle withstands, even reach the pressure that makes the float-controlled valve come-up in the heating kettle, float-controlled valve can not continue come-up sealing valve opening, so pressure just can not continue increase.In sum, the pot cover 9 that closes that when cooking food, aims the place, rotating to an angle makes it to close fully the jail, and heating back pressure rises, and float-controlled valve floats the sealing valve opening, and its upper end penetrates the hole 4 of covering handle.Drop to when very low when heating finishes the back pot inner pressure, float-controlled valve falls, and the opposite spin pot cover is opened pot cover when getting food, and the upset pot cover is to Fig. 3 position.

Sometimes in order to clean pot cover, can be it from transposase 11 or revolve post 7 and remove.Rotating shaft 2 or revolve post 7 and should make the pattern of easy mounting or dismounting in advance for this reason; For the ease of rotation folding pot cover, can connect the good-looking annex of moulding in the pot cover appropriate location.For the intensity of strengthening pot cover makes it indeformable, can be on the pot cover of lid below the handle or other suitably local hill or reinforcements of connecting.

The above is an embodiment of the present utility model, and also having another embodiment is for the security that solves easing valve.Because the use occasion difference of pressure cooker also requires difference to its security insurance performance.The easing valve of existing pressure cooker is that also having another kind is directly to utilize the sealing ring under the pot cover to come relieving pressure with eutectic point alloy sheet and spring pearl, though a kind of mode safety in back, troublesome poeration, cost is higher.And that the easing valve that utilizes eutectic point alloy sheet and spring pearl belongs to small holes is closed, still dangerous factor.Easing valve of the present utility model adopts the outer open form structure of large tracts of land, and its steam vent is very big, generally can not be plugged fully, even block, and because it is outer open form, also can outside immediately exhaust, can not resemble closed stifled more tight more.Fig. 3 is the cross-sectional schematic of present embodiment.

As Fig. 3, on the appropriate location of pot cover, have a diameter at least greater than the hole more than the 6mm 12, sealing ring 11 blind holes 1.2, briquetting 13 is pressed on the sealing ring, and briquetting 13 can be as the shape of Fig. 3, also can be one plane.There is spring leaf 14 sealing ring 11 outsides, and spring leaf 14 lower ends are connected on the pot cover 9, and spring leaf 14 can be that the sheet of strip is always done, and also can be that a spring leaf is washed into trident or four forks are made, and the connection of spring leaf top tightens bolt 15 and compresses briquetting 13.Tightening bolt can be to weld extremely to be fixed on the spring leaf, also can be with being threaded on the spring leaf.Like this, when other safety components were invalid, one surpassed the elastic force of spring leaf, and this easing valve is with exhaust immediately.

The utility model makes the more convenient safety of pressure cooker.
