Embodiment 1

[0036] Such as figure 1 As shown, a cover opening device of the present invention is used to openably connect the cover body 1 to the main body 2, which includes

[0037] A fixing groove 6 is formed on the main body 2;

[0038] The hinge shaft 5 is installed on the cover body 1, and its two ends can be respectively pressed into the corresponding fixing grooves 6;

[0039] The forward biasing member 4 is sleeved on the hinge shaft 5, and the biasing force of the forward biasing member 4 acts on the cover 1, so that the cover 1 has a tendency to open the cover;

[0040] The reverse bias member 3 is sleeved on the hinge shaft 5, and the bias force of the reverse bias member 3 acts on the cover body 1 to damp the opening of the cover body 1 ;

[0041] The limit structure is installed on the main body 2 after the hinge shaft 5 is pressed into the fixing groove 6, and is used to prevent the hinge shaft 5 pressed into the fixing groove 6 from coming out of the fixing groove 6 ; ...

Embodiment 2

[0050] The difference between Embodiment 2 and Embodiment 1 lies in that: the connection structure corresponding to the forward biasing member 4 arranged on the hinge shaft 5 to the forward third of the forward biasing member 4 The distance between the ends of the two torsion arms 42 is shorter than the distance between the connecting structure corresponding to the reverse bias member 3 and the end of the reverse second torsion arm 32 of the reverse bias member 3, so that The forward second torsion arm 42 of the forward biasing member 4 can be connected with the corresponding connecting structure before the hinge shaft 5 is pressed into the fixing groove 6, and the reverse biasing After the hinge shaft 5 is pressed into the fixing groove 6, the opposite second torsion arm 32 of the pressing member 3 can be connected with the corresponding connecting structure.

[0051] The length of the forward second torsion arm 42 of the forward biasing member 4 is shorter than the length of...

Embodiment 3

[0054] In this embodiment 3, on the basis of embodiment 1 or embodiment 2, the number of forward bias members 4 and reverse bias members 3 is adjusted, specifically, the number of forward bias members 4 and the reverse bias members The number of the biasing parts 3 is the same, and the forward biasing parts 4 and the reverse biasing parts 3 are arranged in a staggered interval.

[0055] A pot of the present invention has the above-mentioned cover opening device, wherein the main body 2 is a pot body, the cover body 1 is an inner cover of the pot, and the position-limiting structure is an outer cover of the inner cover.

[0056] The cooker is an electric rice cooker or an electric pressure cooker.

[0057] Introduce the installation process of the uncapping device of the present invention below with the structure of embodiment 1:

[0058] Now the positive first torsion arm 41 of the forward biasing part 4 and the reverse first torsion arm 31 of the reverse biasing part 3 are a...

Abstract

The invention provides a lid opening device and a cooker, wherein the lid opening device comprises: fixing grooves formed in a body; a hinge shaft mounted on a lid, wherein two ends of the hinge shaft can be pressed into the fixing grooves respectively; positive biasing parts; a reverse biasing part; a limiting structure for limiting the hinge shaft mounted in the fixing grooves. Both positive first torsion arms of the positive biasing parts and a reverse first torsion arm of the reverse biasing part are connected to the lid. Before the hinge shaft is pressed into the fixing grooves, one of positive second torsion arms of the positive biasing parts and a reverse second torsion arm of the reverse biasing part is in contact connection with a corresponding connection structure of the body. After the hinge shaft is pressed into the fixing grooves, the other one of the positive second torsion arms of the positive biasing parts and the reverse second torsion arm of the reverse biasing part may be in contact connection with the corresponding connection structure of the body. The lid opening device herein allows the biasing parts to be fitted in position quickly and effectively, and no poor quality occurs where the biasing parts are fitted mistakenly.

Description

technical field [0001] The invention relates to the field of cooking utensils, in particular to a cover opening device and a pot. Background technique [0002] The currently used electric rice cooker or electric pressure cooker includes a pot cover and a pot body, wherein the pot cover and the pot body are connected by a hinge shaft, and the hinge shaft passes through several torsion springs, and its two ends are stuck in the slot of the pot body. The protruding ends of the two ends of the torsion spring are respectively stuck on the pot body and the pot cover wall. At the same time, damping ribs are provided at the junction of the inner cover assembly and the outer cover assembly, and elastic damping members (generally rubber damping block), when the lid is opened, the lid springs off under the action of the torsion spring, but due to the interference fit between the damping rib and the elastic damping part, a damping effect is produced, so that the lid is opened slowly.
