Description

cooking utensils

technical field

The utility model relates to a cooking utensil for daily use, in particular to a cooking utensil capable of delaying the speed at which a pot cover bounces off.

Background technique

The Chinese patent 200620055945.4 applied by the applicant discloses a cooking utensil such as an electric rice cooker. A cam that rotates synchronously with the cover is provided on the hinge shaft connecting the pot cover and the pot body. R-shaped elastic brake plate. The above structure utilizes the friction force generated by the convex part of the cam to press the elastic brake plate to effectively delay the speed of the pot lid popping off. However, due to the limitation of the material of the brake plate, it is difficult to achieve a balance between its mechanical strength and elasticity. After a long time of use, Repeated opening and extrusion can easily cause breakage at the bend of the R-shaped elastic brake plate, which affects the quality of the product.

Utility model content

The purpose of the utility model is to consider the above-mentioned problems and provide a cooking utensil with reliable performance that can delay the speed of the pot cover popping off.

A cooking utensil designed for this purpose, including a pot body and a pot cover hinged by a hinge shaft, a torsion spring and a cam that rotates synchronously with the cover are sleeved on the hinge shaft, and the two ends of the torsion spring are separately arranged on the pot body and the pot cover , The pot body is provided with a damping device for delaying the rotation of the cam, wherein the above-mentioned damping device includes a spring leaf fixed on the pot body at one end and in contact with the cam at the other end, and an elastic damping block installed between the pot body and the spring leaf.

A brake plate is installed on the above-mentioned pot body, and the upper end of the brake plate is set on the hinge shaft. One end of the spring piece is fixed on the brake plate, and the other end is in contact with the cam. The elastic damping block is installed between the brake plate and the spring piece. .

The above-mentioned pot body is provided with a detent that defines an elastic damping block.

The brake plate is provided with a detent that defines an elastic damping block.

The above-mentioned elastic damping block is a rubber block, a silica gel block, a spring or a corrugated plate.

The working principle of the utility model is as follows: in the process of opening the pot cover, the cam rotates with the cover, and the contact point on the cam and the spring piece is gradually transferred to the convex part of the cam, and the distance between the contact point and the cam axis gradually increases , so that the spring piece deforms, and the elastic damping block is also deformed when it is squeezed, forming double damping, increasing the friction between the cam and the spring piece, and slowing down the speed at which the cover bounces off.

Because the utility model adopts the structure of the double damping device, it avoids the large-angle bending of the cam pressing the damping device in the process of popping the pot cover, thereby eliminating the problem caused by the repeated bending of the damping device and the difficulty in balancing its mechanical strength and elasticity. Quality risks such as breakage. The utility model is a cooking utensil with ingenious design, simple structure and reliable performance.

Detailed ways

Example:

The structure of the cooking utensil of the present utility model is shown in Figures 1 and 2, comprising a pot body 2 and a pot cover 1 hinged by a hinge shaft 3. The two ends are respectively arranged on the pot body and the pot cover. The arm of the cam 5 is fastened to the pot cover 1 by the screw 6. The pot body is provided with a damping device for delaying the rotation of the cam 5. The damping device includes one end fixed on the pot body and the other end A leaf spring 8 in contact with the cam 5, and a silicone damping block 9 installed between the pot body and the leaf spring 8.

In order to avoid the wear and tear of the pot cover, a brake plate 7 is installed on the above-mentioned pot body. Walls 71 are arranged on both sides of the upper end of the brake plate 7. The two walls 71 are respectively sleeved on the hinge shaft 3 on both sides of the cam 5, so that the The brake plate 7 can also limit the cam 5 and the silica gel damping block 9. One end of the above-mentioned spring plate 8 is fixed on the brake plate 7, and the other end is in contact with the cam 5. The elastic damping block 9 is installed on the brake plate 7. And between the leaf spring 8.

The distance between the contact point of the above-mentioned cam 5 and the spring leaf 8 from the center of the cam axis is the minimum dimension A in the closed state, and the maximum dimension B in the fully opened state, as shown in Figure 5. In this way, in the closed state, the spring The sheet 8 is slightly deformed under pressure, and the damping force received by the cam 5 is also very small, as shown in Figure 3; when the pot cover 1 is popping open, the cam 5 rotates with the cover, and the contact point between the cam 5 and the spring sheet 8 is away from the cam 5 axis. The distance between the centers gradually increases from A to B, so that the compression deformation of the spring sheet 8 gradually increases. When the spring sheet 8 is deformed to contact with the silicone damping block 9, the silicone damping block 9 is deformed under pressure to form a double damping , to achieve the effect of slowing down the pop-up speed of the cover, as shown in Figure 4.

The pot body or brake plate of the cooking appliance in this embodiment is provided with protrusions, grooves and other locking positions to limit the position of the silicone damping block.
