Description

But a kind of electric pressure cooking saucepan of inner cap conveniently assemble and disassemble

Technical field

The utility model relates to the electric pressure cooking saucepan field, and it is a kind of simple in structure to say so more specifically, but cleans the electric pressure cooking saucepan of inner cap conveniently assemble and disassemble easily.

Background technology

In cooking process, inner cap unavoidably can be by food pollution by electric pressure cooking saucepan, and inner cap must often clean, otherwise can produce peculiar smell.And some split type with the pot body of present electric pressure cooking saucepan pot cover, inner cap cleans easily but takes off pot cover will look for local the placement, easily contaminated environment, some pot cover does not separate with the pot body, and inner cap can not be pulled down cleaning, and this type of electric pressure cooking saucepan takies and occupies a narrow space, but clean trouble, not thorough yet.Also having a kind of is that pot cover is connected with pot seat slide rail, though can overcome above two kinds of deficiencies, complex structure, operation inconvenience.

The utility model content

The purpose of this utility model is to solve the shortcoming of prior art, but a kind of electric pressure cooking saucepan of inner cap conveniently assemble and disassemble is provided, so that clean inner cap and middle cover.

For achieving the above object, the utility model by the following technical solutions.

But the design is a kind of electric pressure cooking saucepan of inner cap conveniently assemble and disassemble, structure comprises pot body and pot cover, pot cover includes inner cap, middle cover and cover, inner cap and pot body are respectively equipped with the button tooth that mutual rotation cooperates, pot body and pot cover are connected through the hinge, and are provided with the tumbler that is connected with inner cap in the middle of the pot cover, and the tumbler below is provided with a main shaft and passes the inner cap center, the main shaft lower end is provided with screw thread, by the fixing inner cap of nut.The utility model cooperates by nut and main shaft, and inner cap is fixed on the tumbler, can rotate with tumbler during use, fastens mutually with the button tooth of pot body, realizes that the pot cover and the locking of pot body fasten.When needs clean inner cap and middle cover, only need back out nut, promptly can split out inner cap, clean, use very convenient.

The design makes hollow structure with main shaft for simplified structure, forms the exhaust plug structure, and described nut side is provided with the pore that communicates with exhaust plug.Adopt the structure of main shaft and exhaust plug integral type, simplify the structure, improved stability in use.

Can not relatively move between inner cap and the tumbler in order making, between inner cap and whirligig, to be provided with location structure, as configuration of post hole or axis hole configuration.

For the ease of dismounting, the shaft shoulder of air bleeding valve spool has sealing ring, and nut is made cylindricality or butterfly, and the lower surface is provided with straight trough, and the outside is provided with shallow line.

Be to improve the security performance of pressure cooker, prevent from also not reach under the normal condition and open pot cover, cause dangerous generation, cover in the utility model and be provided with float-controlled valve at pressure, in cover and be provided with and the corresponding safety vent of float-controlled valve.

The structure that the utility model adopted when pot cover need clean, can simply be pulled down inner cap, convenient cleaning to inner cap and middle cover, use very simple and conveniently, and be provided with the multiple measure of being convenient to manual teardown, have higher hommization setting.Also be provided with safety device, guaranteed the safe in utilization of pressure cooker.Have substantive distinguishing features and progress with respect to prior art.

Description of drawings

Fig. 1 is a section of structure of the present utility model;

Fig. 2 is the enlarged drawing of A position among Fig. 1.

The specific embodiment

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

In conjunction with illustrated in figures 1 and 2, the utility model includes pot body 4, interior pot 3, tumbler 15, air bleeding valve 12, float-controlled valve 18, enclosing cover 17, middle cover 16, inner cap 13.Tumbler 15, air bleeding valve 12, float-controlled valve 18, enclosing cover 17, middle cover 16, inner cap 13 are combined into pot cover.

Pot cover forms hinge with pot body 4 and is connected, tumbler 15 bases are provided with two arc grooves 152, in be covered with two small convex pillars 161, tumbler 15 is put into middle cover 16, arc groove 152 on tumbler 15 bases matches with middle cover small convex pillar 161, make tumbler 15 freely rotate an angle, its angle also can make inner cap 13 be interlocked with pot body 4 or separate.Screw 20 makes tumbler 15 can not break away from middle cover 16.

The base center fixation of tumbler 15 is equipped with air bleeding valve 12, and air bleeding valve spool lower end is provided with screw thread, and the mesopore of inner cap 13 penetrates the lower end of air bleeding valve spool, tighten up by nut 11, inner cap 13 and turning knob 15 are formed a fixed connection, back out nut 11, inner cap 13 promptly unloads.Inner cap 13 has corresponding location structure with tumbler 15 bases, as post 131 and post hole 151.Make inner cap 13 and tumbler 15 be fixed on the relevant position, can not relative motion.Turning knob 15 goes to inner cap 13 when being interlocked the position with a pot body 4, be contained in float-controlled valve 18 on the inner cap 13 over against the safety vent 162 of middle cover 16, when in the pot pressure being arranged, float 181 come-ups are passed middle cover safety vent 162, inner cap 13 and tumbler 15 are stuck, and can not rotate.When tumbler 15 does not forward inner cap 13 to and fastens fully with a pot body, even produce steam in the pot, make the float come-up, also blocked by middle cover 16, float-controlled valve 18 is in exhaust condition always can not go up pressure.Guaranteed the accurate fastening of pot cover like this and avoided under high pressure opening pot cover the danger that produced.
