Abstract

The utility model relates to a pressure cooker, which comprises a cooker body, a cooker lid, a safety valve and a pressure valve. The cooker lid is provided with a clamp-shaped opening and closing device. The cooker lid can be opened like a bird so long as an opening button is mildly pushed because the utility model adopts a clamp-shaped anchor ear to be used as the opening and closing device. The cooker lid can be closed when a press lid is pressed, and the opening and the closing are convenient. The pressure valve is provided with a pressure regulating device which is suitable for requirements of different pressures when different foods are cooked. The cooker lid is provided with a lock which can prevent the pressure cooker from opening when the pressure cooker has pressure. The bottom of the cooker body is a composite bottom, and the cooker bottom has high heat-transfer efficiency, and is hard to deform.

Description

Pressure cooker

The utility model relates to a kind of pressure cooker, particularly a kind of pressure cooker.

At present, pressure cooker is made up of pot body, pot cover substantially.Be respectively equipped with bakelite handle on pot body and pot cover, turning handle is realized the keying of pressure cooker.This type of pressure cooker is because bakelite handle is stressed bigger in the switching process, and handle damages easily, opens and closes also not very convenient.Pressure cooker does not generally have pressure-regulating device.Be difficult to adapt to different foods when hotting plate, need the requirement of different pressures.If aluminium matter pressure cooker, its bottom of a pan is yielding; And the normal phase uses health is had harmful effect.

The purpose of this utility model is: a kind of conveniently opening and closing is provided, can carries out pressure controlled pressure cooker.

In order to reach the above purpose, the utility model is achieved through the following technical solutions:

A kind of pressure cooker comprises a pot body, pot cover, safety valve and pressure valve, and pot cover is provided with a clamp-shaped headstock gear, and two clamp-shaped anchor ears extend relatively-movable guide plate, is connected by extension spring between two guide plates, and projection is set respectively on the guide plate; It is corresponding with two projections that one wedge unlatching button horizontal direction is carved face; The press cover bottom is provided with the wedge post, and it carves face, and to carve face corresponding with opening the button vertical direction, is provided with returning spring in press cover is moulded circle; Have the slotted hole that can allow projection move on the guide rail plate, press cover is connected with the guide rail plate.

Described pressure valve is the pressure-adjusting type pressure valve, comprise escape pipe, at knob core body, the knob housing of escape pipe outlet, be located at the regulating spring between knob core body and the adjusting knob.

On two guide plates of clamp-shaped anchor ear, have a pair of perforate, be provided with a lock in the perforate.

The bottom of pot body is the compound end.

Advantage of the present utility model is: because the utility model adopts the clamp-shaped anchor ear to make headstock gear, just can like a cork pot cover be opened as long as touch the unlatching button; Press press cover and just pot cover can be closed, open and close very convenient.Because pressure valve is provided with pressure regulating device, can adapt to different foods when hotting plate, need the requirement of different pressures.Owing on pot cover, be provided with lock, open pressure cooker in the time of preventing from the pot certain pressure to be arranged.Because the bottom of pot body is the compound end, the bottom of a pan heat transfer efficiency height, and the bottom of a pan is not yielding.

For clearer explanation the utility model, be elaborated below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a vertical view of the present utility model.

Fig. 3 is a headstock gear structure enlarged drawing of the present utility model.

Fig. 4 is the structure enlarged drawing of pressure regulator valve of the present utility model.

As Fig. 1, Fig. 2, shown in Figure 3, the bottom of pot body 1 is the compound end, the bottom of a pan heat transfer efficiency height, and not yielding.Pressure cooker can be placed on such as heating on the heating elements such as electric hot plate, electromagnetic stove.On pot cover 2, be provided with safety valve 3 and pressure valve 4.Pot cover is provided with a clamp-shaped headstock gear, and two clamp-shaped anchor ears 5 extend between relatively-movable guide plate 6, two guide plates continuous by extension spring 7, and projection 8 is set respectively on the guide plate; Have on the guide rail plate 12 and can allow slotted hole 13, one wedges that projection moves open button 9 to be located at press cover and to mould between circle 10 and the panel 11, it is corresponding with two projections that its horizontal direction is carved face.Press and open button 9, the face of carving of its horizontal direction backs down the projection on the guide plate 68, thereby drives clamp-shaped anchor ear 5, opens pot cover.Press cover 14 bottoms are provided with wedge post 15, and it carves face 17, and to carve face corresponding with opening button 9 vertical direction, is provided with returning spring 16 in press cover is moulded circle 10; Press cover 14 is connected with guide rail plate 12.Press press cover 14, wedge post 15 is carved face and will be opened button and back down by opening button 9 vertical direction.Because the effect of 6 extension springs 7 of two guide plates, closure is very light.

As shown in Figure 4, pressure valve is a pressure-adjusting type pressure valve 4, comprise escape pipe 19, at the knob core body 20 of escape pipe outlet, be located at the regulating spring 18 between adjusting knob 21 and the knob core body 20.Knob housing 22 is provided with the spiral terrace 23 of differing heights, is provided with on adjusting knob 21 and step 23 corresponding projectioies 26.Rotate adjusting knob 21, the projection on the knob snaps in different steps.Because the effect of regulating spring, the knob core body has produced different pressure to the gas outlet, thereby realizes being provided with the pressure in the pressure cooker.

As shown in Figure 3, have a pair of perforate 24, in perforate, be provided with a lock 25 at two guide plates of clamp-shaped anchor ear.The lower end of lock is stretched in pot body, and is provided with a sealing ring 27.The middle pars infrasegmentalis of lock is thicker, and top is thinner.When thin portion stretched into perforate 24, two guide plates can relatively move; When thicker part stretched into perforate 24, two guide plates were just locked.When in the pressure cooker during no pressure, the thin portion of lock is positioned at perforate 24, pot cover can be opened.When in the pressure cooker certain pressure being arranged, lock is made thicker part be positioned at perforate 24 by on the pressure top, and pot cover is lockable, and prevents to be opened when pressure is arranged.

In the utility model, clamp-shaped headstock gear or pressure-adjusting type pressure valve can be set separately.If both are used in combination, the performance of pressure cooker will be better.For the pressure cooker that one of clamp-shaped headstock gear or pressure-adjusting type pressure valve only are set, do not should be understood to disengaging protection domain of the present utility model.
