Description

Safe pressure cooker

The utility model relates to a kind of pressure cooker.

Pressure cooker is one of household kitchen tools commonly used, be subjected to the great kindness of cooker deeply owing to the tool high pressure-temperature, but the pressure cooker on the existing market is because design objectively is unreasonable, most pressure cooker lid be by the outside be fastened on the pot on one's body, this design makes its pressure that can bear not high, under high-pressure situations easily by distending.Moreover be that the safety measure of pressure cooker is not enough, much by the pressure cooker of distending, mainly be since pot inner pressure when increasing to the limit that pot can bear safety device can not in time work---exhaust, thus cause pot by distending.In sum, objectively there is following defective in existing pressure cooker: the one, and pot cover and pot body combination are difficult to reach the resistance to compression effect of the best; The 2nd, the exhaust protection effect when high pressure is undesirable.

The purpose of this utility model is to disclose a kind of new safe pressure cooker, and it is good that this pot reaches resistance to compression by the combination of improving pot cover and pot body, the purpose that security performance is high.

Above-mentioned purpose of the present utility model is to implement by such technical scheme, be that the utility model mainly is the new design of combination proposition to pot cover with the pot body of existing pressure cooker, comprise a pot body, pot cover, Button Handle specifically, two automatic exhaust steam valves of the prior art wherein are housed on the pot cover, and the diameter of the upper end boiler port of described pot body is slightly less than pot body diameter and is the shape that caves in.The diameter of described pot cover when opening the state of enduring is greater than the diameter of described pot body boiler port, but when nature, be arch, when described pot cover is arch along the straight length of arcuate surface less than described pot body boiler port diameter, and along the length of vertical arcuate face relatively greater than described pot body boiler port diameter.Described pot cover center is connected with shell fragment and " U " shape connector, and described Button Handle is socketed in " U " shape connector, can move freely along " U " shape connector under the elastic force effect of described shell fragment.The open end of described " U " shape connector is connected with a crank by connecting axle, it is circular-arc that the relative connecting axle of end face of close connecting axle one end of described crank is parabola, and described crank can make described Button Handle move along described " U " shape connector around the connecting axle rotation and by the circular-arc end face of parabola.

The pot mouth of described pot body caves in and locates to be inlaid with an O-ring seal.

The center of described pot cover also is connected with the pressure-sensitive safety rod.

Also be connected with two gum covers on the described pot cover.

The curved shape of described Button Handle, its straight length are slightly larger than the diameter of the boiler port of described pot body.

Described crank is provided with a groove near the circular arc end face of connecting axle one end, and the size of described groove is advisable can pack into described pressure-sensitive safety rod.

Described pot cover adopts the elastic memory alloy-steel plate to make.

After the utility model adopts technique scheme, compared with prior art, its pot cover is the boiler port that closes at pot body under the acting in conjunction of Button Handle and crank from inside to outside, has stronger sealing and compressive property and is difficult for distending, make food ripe faster more thoroughly, advantage such as energy-efficient.Secondly, the gum cover on the pot cover more helps improving security performance, in case gum cover can be helped the exhaust step-down by jack-up when continuing high pressure so that during the value of overstepping the extreme limit.Moreover the operation of crank is to utilize lever principle, and it is light and handy, easy to operate to exert all one's strength.

Below in conjunction with accompanying drawing the utility model is made further enumeration.

Fig. 1 is a partial structurtes schematic diagram of the present utility model;

Fig. 2 is the fashionable schematic diagram of side direction view of " U " shown in Figure 1 shape connector;

Fig. 3 is the side direction view of pot cover shown in Figure 1;

Fig. 4 is the partial structurtes schematic diagram of the utility model when pot cover and pot body are closed.

As depicted in figs. 1 and 2, in the utility model, shell fragment 6, " U " shape connector 3 are connected in turn the center of pot cover 7 by bolt 8, nut 9.Because bolt 8 is a hollow, so can pack into pressure-sensitive safety rod 10 in the bolt 8.Then Button Handle 5 is socketed in " U " shape connector 3 again, and Button Handle 5 is pressed down back by the last crank 1 of connecting axle 2 connections.

Pot body 12 is at boiler port and caves in, and promptly the diameter of boiler port is slightly less than the diameter of pot body 12, is inlaid with an O-ring seal 11 at the pot mouth place of caving in.Pot the neglecting concrete actual conditions greatly of body 12 and deciding, also can be provided with in it steaming every etc.As shown in Figure 3, pot cover 7 is to adopt the elastic memory alloy-steel plate to make, has strong elastic memory function, the automatic vent dress valve 13 of two prior aries is housed thereon, this pot cover 7 also is equipped with two gum covers 14, this gum cover 14 can guarantee that pressure cooker can be softened jack-up to the utmost point in limited time at the continuous high temperature high pressure, thereby reaches safer row pressure.This is arch to pot cover 7 shown in the figure under nature, along the straight length of arcuate surface less than pot body 12 boiler port diameters, the length of the relative vertical arcuate face in edge then greater than described pot body 12 boiler port diameters, just can be stuck in boiler port when making its Zhang Tingwei sphere from inside to outside.

As shown in Figure 4, will be connected with pot covers 7 such as Button Handle 5, crank 1 to lopsidedness, because pot cover is arch shape when nature, and along the straight length of the arcuate surface diameter less than pot body 12 boiler ports, so pot cover can be put into a pot body to lopsidedness the time.Utilize lever principle, pull down crank 1 along connecting axle 2, because it is circular-arc that the relative connecting axle 2 of end face of crank 1 close connecting axle 2 one ends is parabola, when crank 1 when connecting axle 2 rotates, the circular-arc end face of the parabola of crank 1 can make Button Handle 5 move down along " U " connector 3, in the time of on being displaced downwardly to the pot mouth that is stuck in pot body 12, continuing to pull down 1 on crank can move for supporting on the pulling pot cover 7 by Button Handle 5, this moment pot cover 7 along the boiler port of two end in contact pot bodies 12 of vertical arcuate face and withstand O-ring seal 11; Be subjected to the drive of crank 1, pot cover 7 moves on constantly to be subjected to open and very overcomes elasticity and very be sphere, and the O-ring seal 11 of being close to the boiler port that is embedded in pot body 12 is tight closure.Groove 4 on the crank is over against pressure-sensitive safety rod 10 at this moment.Pot body 12 is heated, and pot inner pressure increases progressively, and then the pressure-sensitive safety rod is packed in the groove 4 by jack-up, crank 1 is stuck and can not opens pot cover 7.After culinary art finished, when pot inner pressure was reduced to normal pressure, pressure-sensitive safety rod 10 dropped under the effect of gravity and groove 4 from crank 1 is deviate from, and pulled crank 1 and made the pot cover 7 loose natures that are arch, just can close behind lopsidedness and take out pot cover 7.
