Problems solved by technology

However, there are many defects in this method: welding process cost; welding is unreliable, prone to false welding or false welding, affecting the strength and causing safety hazards; moreover, the bottom of the thin-walled outer pot cannot withstand the pressure in the pot
Therefore, the process of the electric pressure cooker will be complicated, the safety will be poor, and the life span will be short.

Embodiment 1

[0025] Such as figure 1 , figure 2 , Figure 4 As shown, this embodiment includes a switch 9 connected to the control circuit, an outer pot 5, an inner pot 4 that can be accommodated in the outer pot 5, a pot lid 1 with lid teeth that is fastened on the outer pot 5 and placed The heating device 6 on the bottom surface of the outer pot 5, wherein the outer pot 5 is a thin-walled structure with a pot wall thickness not greater than 0.5 mm, and the above-mentioned switch 9 connected with the control circuit is arranged below the edge of the outer pot 5. The outer pot 5 is fixedly connected with buckle teeth 7 along the outer wall. The main body of the buckle teeth 7 is a ring structure, and its lower end is screwed to the upper part of the outer pot 5. The main body of the buckle teeth 7 is evenly distributed with pot teeth corresponding to the lid teeth of the pot cover 1. , The pot teeth are arranged on the button teeth 7 and are screwed to the other end of the outer pot. I...

Embodiment 2

[0030] The difference from the first embodiment is the same, such as figure 2 , image 3 As shown, the pot tooth on the main body of the button tooth 7 in the present embodiment forms a boss structure 72, corresponding to this, the pot cover 1 covers the groove structure of the inner buckle, and the pot cover 1 is buckled by its cover tooth. The groove structure is fastened on the boss structure 72 of the pot tooth and connected with the outer pot 5, that is, the connection between the pot cover 1 and the outer pot 5 adopts an external rotation connection.

Abstract

The invention discloses a safety electric pressure cooker comprising a switch, an outer pot, an inner pot, a cooker cover and a heating device, wherein the switch and the outer pot are connected with a control circuit; the inner pot can be accommodated in the outer pot; the cooker cover can be buckled on the outer pot and is provided with cover teeth; and the heating device is arranged on the bottom surface of the outer pot. The safety electric pressure cooker is characterized in that the outer pot is fixedly connected with buckle teeth along the outer wall; an elastic body is arranged between the buckle teeth and the outer pot; one end of the elastic body is pressed against the buckle teeth; the other end of the elastic body is pressed against the edge of the outer pot; and the cooker cover is embedded with the buckle teeth and connected with the outer pot. According to the invention, by adopting the mode of independently producing the outer pot and the buckle teeth and fixedly connecting the outer pot with the buckle teeth, the outer pot can be made of thin material; the outer pot bears pressure to cause the elastic body to deform, thereby generating displacement; meanwhile, the buckle teeth are made of thick material, so that the buckle teeth have enough strength to bear the pressure intensity. The electric pressure cooker has the advantages of low cost, more reliable performance, higher safety and more convenience for operation.

Description

technical field [0001] The invention relates to the field of electric pressure cookers, in particular to a safe electric pressure cooker, which belongs to the improvement technology of electric pressure cookers. Background technique [0002] Electric pressure cookers currently on the market generally use the lower edge of the pot lid and the upper edge of the outer pot to make a matching structure. After the outer pot is stretched into a barrel shape, several protrusions are made on the outer circle of the upper edge. These protrusions The part is matched with the rounded protruding part of the pot cover, and the upper and lower protruding parts are used to fit together to withstand the pressure in the pot. When the steam pressure is generated in the pot, the pot cover and the outer pot are rigidly connected, and the electric heating plate is elastically supported. , the inner pot is forced to move downward, the electric heating plate bears pressure, the supporting elastic b...
