Description

Technical Field

[0001] This utility model relates to the field of cooking appliance technology, and in particular to a pressure cooker with a button opening and closing structure. Background Technology

[0002] A pressure cooker, also known as a pressure cooker, is an energy-efficient cooking appliance. It works by utilizing the physical phenomenon that the boiling point of a liquid increases under higher pressure. By applying pressure to water, it raises the water temperature without boiling, thus speeding up the cooking process. It can heat food to over 100°C. In high-altitude areas, pressure cookers prevent the problem of water's boiling point lowering and food becoming difficult to cook thoroughly. The advantages of a pressure cooker are not only shorter cooking time but also better-tasting food, especially meats that are difficult to cook through, resulting in a smoother texture and better flavor.

[0003] To achieve a tight seal between the pot body and lid for safe pressure increase, various types of pressure cookers have been designed. Based on the closure method, they can be categorized as screw-on pressure cookers, pressure-sealing pressure cookers, drop-off pressure cookers, clamp-type pressure cookers, and so on. Currently, screw-on pressure cookers are the most widely used. By rotating the lid, the originally misaligned upper and lower teeth on the pot body and lid interlock, achieving a seal. However, users of this type of pressure cooker need to rotate the lid multiple times to achieve the interlocking of the teeth, making operation inconvenient. Existing technology achieves a seal through a rotating interlocking mechanism between the pot body and lid. When opening the lid, if the pot body is heated by an external heat source, the surface temperature is high, requiring heat insulation measures. Furthermore, opening the lid requires two hands—one to hold the pot body and the other to rotate the lid—making operation inconvenient. Few pressure cookers on the market achieve the same purpose through a button-operated opening mechanism. Additionally, most pressure cookers have non-removable lids, panels, and buttons, making assembly, repair, and maintenance difficult. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a pressure cooker with a button opening and closing structure.

[0005] To solve the above-mentioned technical problems, this utility model provides a pressure cooker with a button opening and closing structure, including a lid and a pot body, as well as a rotating shaft, a linkage plate, a first connecting plate, a second connecting plate, a transmission block, a button, and a clamp;

[0006] The rotating shaft is located in the middle of the pot lid, and the linkage plate is rotatably mounted on the rotating shaft. The first connecting plate and the second connecting plate are symmetrically and rotatably connected to both sides of the linkage plate. The transmission block is located on the first connecting plate, and the button is located on the pot lid. The transmission part of the button is driven by the transmission block. The end of both the first connecting plate and the second connecting plate is provided with the clamp. When the button moves the transmission block, the first connecting plate slides and, through the linkage plate, the second connecting plate slides synchronously, so that the clamp opens or closes the pot body.

[0007] Furthermore, the upper wall of the transmission block is provided with a first tooth, and the transmission part of the button is provided with a second tooth that engages with the first tooth.

[0008] Furthermore, a transmission shaft is provided on the upper part of the transmission block, and the transmission part of the button is provided with a curved groove that cooperates with the transmission shaft.

[0009] Furthermore, the pot lid is provided with a handle, the pressing part of the button is exposed on the handle, and the transmission part has a first connecting shaft and a second connecting shaft on both sides respectively. The first connecting shaft is rotatably disposed in the handle, and the second connecting shaft is disposed in the handle through a rotating assembly.

[0010] Furthermore, the rotating assembly includes a cover, a rotating ball, and an elastic element. The cover is fixedly disposed inside the handle, and the elastic element and the rotating ball are both disposed inside the cover. The second connecting shaft is rotatably connected to the rotating ball.

[0011] Furthermore, a guide groove is provided inside the pot lid, and the first connecting plate and the second connecting plate move radially along the guide groove.

[0012] Furthermore, the caliper engages with the circumferential outer edge of the top of the pot body.

[0013] Furthermore, a retaining ring is provided on the outer wall of the pot body.

[0014] Furthermore, a sealing ring that mates with the pot body is provided inside the pot lid.

[0015] Implementing the embodiments of this utility model has the following beneficial effects:

[0016] Pressing the button causes the transmission block to slide, the first connecting plate to slide inward and drive the linkage plate to rotate, the second connecting plate to slide inward simultaneously, causing the clamp to close, and the pot lid to engage with the outer edge of the pot body; flipping the button causes the transmission block to slide, the first connecting plate to slide outward and drive the linkage plate to rotate, the second connecting plate to slide outward simultaneously, causing the clamp to open, and the pot lid to separate from the outer edge of the pot body.

[0017] It is equipped with a button and its cooperating shaft, linkage plate, first connecting plate, second connecting plate, transmission block and caliper. The structure of each part is compact. The lid can be opened and closed by pressing or flipping the button with one hand. Its opening and closing structure is reliable and durable, and it is not easy for the button to jam or for the resistance to be too great. Users can open and close the lid smoothly. It is also small in size and easy to carry when going out.

[0018] The first and second connecting plates, which are arranged oppositely and symmetrically, slide within the guide groove, ensuring that they are always in a straight line, thus ensuring smooth and unobstructed opening and closing of the lid. Attached Figure Description
