Abstract

The utility model relates to a safety pressure cooker which abolishes the connection of a cooker body and a cooker lid by a fastening hook claw. The left and right opposite sides of the cooker body are provided with handles, and a tower-shaped spring is arranged on the cooker lid; the top end of the tower-shaped spring is provided with a transverse press rod, both ends of which are penetrated and buckled on the handles of the cooker body, and the transverse press rod is connected with the tower-shaped spring by an adjusting bolt which is used for adjusting the pressure of the tower-shaped spring to the cooker lid. The cooker is connected with the cooker lid by arranging a sealing rubber ring between the cooker body and the cooker lid.

Description

Safe pressure cooker

The application belongs to the safe pressure cooker of A47 household goods technology.

The existing defective of prior art for all pressure cooker without exception be a pot body, have the fastening hook of using on the pot cover, this hook is real to belong to dangerous design, is the root of overvoltage blast, and pot body wall is thick 5 millimeters, it is strong that it bears the overvoltage damage capability, in case superpressure blast consequence is serious, the thing that the pressure cooker blast is hurted sb.'s feelings, the time what is heard arranged, and this type of technology machining process is complicated, the production cost height.

The normal working pressure of pressure cooker is 2.2 atmospheric pressure, the intensity of fastening hook is born destructive power very greater than 2.2 air pressure, and existing improvement way is to increase some auxiliary equipments on the original basis, and a common pot for cooking rice more changes more complicated as a result, and root problem still exists, and does not get rid of.Existing pressure cooker structure is pot body, the pot cover that has fastening hook, pot cover is provided with easing valve, and the usefulness that keep-ups pressure withhold valve port, heavily vertical, in case easing valve is blocked malfunctioning, withholds valve and can fill in for easing valve and continue to discharge steam, when moisture in the pot will evaporate when dried, temperature will increase severely, pressure jump surpasses the intensity of fastening hook and explodes, and breeds a tragedy.

Will guarantee in fact has certain pressure in the pot, so that the way of cooking fast need not be sought help from pot body, the pot cover of being with fastening hook, the simplest as long as satisfy two conditions: as 1, an O-ring seal that can keep-up pressure will to be arranged; 2, add institute's palpus pressure to pot cover, the pressurization of most convenient is pressed on the pot cover no more than picking up several common bricks, owing to there is not securing member, can quick-friedly not do.

The purpose of application case is to revise the structure of now using pressure cooker, and removing a hidden danger reaches the purpose of safe handling, and way is: abolish original fastening hook, establish handle [4] in the and arranged on left and right sides of pot body [1].This handle [4] also is the hook of horizontal depression bar [5] and keeps the required of pot body [1] internal pressure.Settle below horizontal depression bar [5] mid point one for maintenance palpus pressure and have the turriform spring [6] of superpressure scavenging action.Settle the pressure that to regulate turriform spring [6] between turriform spring [6] and the horizontal depression bar [5], play the adjusting bolt [7] of anastomosis.Pot inner pressure surpasses the pressure of turriform spring [6], and pot cover [2] is lifted, and superpressure is eliminated, pot cover [2] reposition.

Advantage with the turriform spring is simple and convenient, good stability, and the flexible scope of adjusting is big, also more attractive in appearance, if need strengthen elastic force, also available one big, little two turriform spring coaxial packages, for better stability, the spring silk of turriform spring is got left-hand screw, one for one and is got right-hand screw.

Pot body [1], the connection place of pot cover [2] must add O-ring seal [3] sealing, for when the overvoltage exhaust, O-ring seal [3] is unlikely to be deflated to dash and to take off, the mouth limit of pot body [1] make proper width to upper overturning, with support O-ring seal [3], and the back taper place of O-ring seal [3] makes the shirt rim of proper width to downward Shen, the shirt rim is book gradually, and wedgewise is pressed close to a pot body [1] sidewall.

Pot cover [2] periphery also is the place of overvoltage exhaust, avoids exhaust to hurt sb.'s feelings, and its periphery should make shirt rim in the wrong downwards, and exhaust is sprayed downwards.

The described safe pressure cooker of this programme also can be simplified, it is above-mentioned horizontal depression bar [5], turriform spring [6], regulate the available spring cross bar [8] with certain elastic force of bolt [7] and replace, spring cross bar [8] is similar to be connected with the also available plane of load-bearing steel plate bullet O-ring seal [3] between the axletree as the gas vehicle carriage.

Existing aluminium pot for cooking rice is with 0.5 millimeters thick aluminium gold alloy sheets punching press, and the safe pressure cooker sheet material of this programme is suitable thicker, consideration employing 1-3 millimeters thick.Too thick processing difficulties, too book is yielding, loses sealing function.

This programme design is finished in the seventies, and the price of pressure cooker was a 20-30 unit at that time, and family has one pot, and is very convenient, expects to purchase several pots more, but to that fastening hook, total worried.After then drop.The eighties once wanted to propose patent application, and doubt have to be put down again and not show to kind thought attractive in appearance of society again.The appearance design of existing pressure cooker, making the grade beyond doubt, nothing to find fault with, be without rebuke.If make cost with safety, then real genus is improper.

The embodiment accompanying drawing:

Figure 1 shows that band double tower shape spring person, attachment bolt [7] need not be with handle.

Figure 2 shows that with a spring cross bar [8], be not with adjusting.

Figure 3 shows that the structure of a pot body [1] mouthful limit and O-ring seal [3].
