Abstract

The utility model relates to a pressure cooker cover, which is divided into two layers. A first layer is a cover top layer, a second layer is a fastening thread layer, fastening threads are arranged on the fastening thread layer and used for fastening a cooker body, and a sealing ring is mounted on the periphery of the cover top layer. The cover top layer is a peripheral wall, the cover top periphery of the cooker cover downwards stretches to form the peripheral wall, the cover top layer and the fastening thread layer of the cooker cover are connected via a connecting plane, the inner periphery of the connecting plane is connected with the lower edge of the peripheral wall of the cover top layer, and the outer periphery of the connecting plane is connected with the fastening thread layer. The fastening thread layer connected to the outer periphery of the connecting plane is a peripheral wall formed by downwards stretching the outer periphery of the connecting plane. The pressure cooker cover has the advantages that the cooker cover is divided into two layers instead of three layers, materials of a cooker cover of 4L in the prior art can be made into the pressure cooker cover of 6L, materials of about 10% are saved, steps of production process are reduced, production cost is lowered, and purposes of simple structure, safety, reliability, low production cost, low carbon, environmental protection and energy conservation are achieved.

Description

Pressure cooker lid

Technical field

The utility model belongs to the pot accessory, particularly a kind of firm holding sealing ring on pot cover, pressure cooker lid, belong to the technological improvement of existing pressure cooker lid hermetically-sealed construction.

Background technology

Survival and development for enterprise; What did not stop in the capital develops new product; Develop new product and be mainly reflected in dual mode: the one, increase new function; As on the basis of piezoelectricity pot, realizing automation, on the basis of electric cooker, increase the function of pressure cooker in other words, just the related electric pressure cooking saucepan of the application.Second kind is to be lowered into original lifting competitiveness through technological improvement, and the application just belongs to this type.

Existing pressure cooker or electric pressure cooking saucepan etc. before use, sealing ring is loaded onto and is positioned at pot cover and pot behind the pot cover and mouthful goes up its sealing, heating makes and produces the purpose that pressure is realized the high pressure culinary art in the pot.

Existing cover structure generally is divided into three layers; Ground floor is a cap layer; The second layer is that sealing ring is stayed layer; The 3rd layer is button tooth layer, and like Chinese patent: 2010201459939,200920060594X, 2008200498604,2007200601808,2006201556400,2005200608884,2003201194514,2003201194482, a plurality of patents such as 992390583 all are to adopt three-decker;

Above-mentioned pot cover is used till today also not see to some extent always and is changed, but it exists volume big, with the many shortcomings of material.

The utility model content

In order to address the above problem, the purpose of the utility model is to overcome the shortcoming of prior art, and a kind of simple in structure, safe and reliable, production cost is low, low-carbon environment-friendly is energy-conservation pressure cooker lid is provided.

The technical scheme that realizes the goal of the invention of the utility model pressure cooker lid is:

This pot cover is divided into two-layer, and ground floor is a cap layer, and the second layer is button tooth layer, and button tooth layer is provided with the button tooth and is used for fastening pot body, and sealing ring is installed on the periphery of cap layer.Cap layer is the circle wall that the caping periphery by pot cover forms to stretched, and its height is between 8 millimeters to 15 millimeters.The cap layer of pot cover with buckle being connected with between the tooth layer and one be connected the plane, the inner rim that connects the plane is connected with the bottom of cap layer circle wall, the neighboring on connection plane with detain the tooth layer and be connected.Being connected in the button tooth layer that connects the neighboring, plane is to connect the circle wall that the neighboring, plane forms to stretched, and its height is between 10 millimeters to 20 millimeters.

The beneficial effect of the utility model is: pot cover changes into two-layer by three layers; Promptly can be made into 6 liters of pot covers of the utility model with 4 liters of pot cover material of prior art; Saved nearly 10% material; Reduced production cost with saving production technology, reached simple in structure, safe and reliable, production cost is low, the low-carbon environment-friendly purpose of energy saving.

Description of drawings

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

Among the figure: 1 is that pot cover, 101 is that cap layer, 102 is that connection plane, 2 is that a pot body, 3 is that sealing ring, 5 is that support chip, 6 is interior pot for buckleing tooth, 4 for buckleing tooth layer, 103.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.

As shown in Figure 1; The pressure cooker lid of the utility model; Support chip 5 three parts by pot cover 1, sealing ring 4 and fixed seal ring 4 are formed; The periphery of pot cover 1 be provided be used for fastening pot body 2 buckle tooth 3, pot cover 1 periphery that its sealing ring 4 is installed in pressure cooker is with pot cover 1 that pressure cooker is provided and the wiper seal between the pot body 2, wherein:

This pot cover divides 1 for two-layer, and ground floor is a cap layer 101, and the second layer is button tooth layer 102, and button tooth layer 102 is provided with button tooth 3 and is used for fastening pot body 2, and sealing ring 4 is installed on the periphery of cap layer 101.

Cap layer 101 is the caping of pot cover 1 and the circle wall that periphery forms to stretched, and its height is between 8 millimeters to 15 millimeters.The cap layer 101 of pot cover 1 with buckle being connected with between the tooth layer 102 and one be connected plane 103, the inner rim that connects plane 103 is connected with the bottom of cap layer 101 circle wall, the neighboring on connection plane 103 with detain tooth layer 102 and be connected.

Being connected in the button tooth layer 102 that connects 103 neighborings, plane is to connect the circle wall that 103 neighborings, plane form to stretched, and its height is between 10 millimeters to 20 millimeters.

Be installed in the sealing ring 4 of pot cover 1 periphery; Sealing circle 4 main body sections are " 7 " font; One side of " 7 " font circle body is designed to a plane; Another side is designed to cambered surface, and its plane is affixed in the pot cover 1 by 5 fixed installations of some support chips, closes interior pot of 6 boiler ports that its cambered surface when cover is affixed on pot body 2.

This cover structure is simple, and materials are few, saves the pillar that stretches out in pot cover inner surface central authorities in the prior art during use, and the aluminium dish is enclosed within on the pillar through an elastic ring, and sealing ring is engaged on the periphery of aluminium dish.Or sealing ring squeezes at the pot cover inner surface periphery through the steel ring that is fixed on the pot cover inner surface; Sealing ring inner ring sidewall is provided with the groove of a circle engagement steel ring; The steel ring inside circumference is provided with two ears, two ears and the welding of pot cover inner surface, existing shortcoming; It is low to have production cost, simple in structure, safe and reliable, low-carbon environment-friendly energy-saving advantages.
