Description

Technical Field

[0001] This utility model relates to a heating container with an all-glass cavity, and more particularly to a glass kettle with a base fixing structure. Background Technology

[0002] Chinese Patent No. ZL202322666798.0, published on August 2, 2024, discloses an assembly structure for a heating plate of an all-glass electric kettle. The structure includes: a kettle body, which is an integral piece of all-glass; a locking support frame fitted onto the bottom of the kettle body; and a heating plate disposed inside the locking support frame for heating the bottom wall of the kettle body. The upper inner ring surface of the locking support frame forms a locking structure with the lower outer ring surface of the kettle body, and the heating plate is supported upwards by the locking support frame, thereby ensuring a tight fit between the top surface of the heating plate and the bottom surface of the kettle body. This structure has a ring-shaped concave-convex fit between the lower outer ring surface of the kettle body and the upper inner ring surface of the locking support frame. During installation, strong pressure needs to be applied to the locking support frame to engage the inner ring surface with the outer ring surface, making it impossible to remove once engaged. Alternatively, removal requires prying until the locking support frame deforms, but the wear caused by this method is irreparable. In addition, the assembly under high pressure causes a certain degree of deformation and wear to the locking support frame. Therefore, a bottom shell needs to be installed outside the locking support frame to cover the worn parts of the locking support frame and form an external decoration. Utility Model Content

[0003] The purpose of this utility model is to provide a glass pot with a base fixing structure that has a simple and reasonable structure, few parts, and is easy to install.

[0004] The purpose of this utility model is achieved as follows:

The bolt is screwed into the screw hole from bottom to top and abuts against the bottom of the heating device; or, the pusher is a compression spring that presses against the bottom of the cavity and the bottom of the heating device.

[0008] As a further embodiment, the base includes a body and a bottom cover, with the upper and lower ends of the body open, and the bottom cover connected to the bottom of the body. The inner side of the body and the bottom cover together form the cavity.

[0009] As a further embodiment, the bottom outer periphery of the glass pot body is provided with a concave annular step, and the connecting thread is provided on the side of the concave annular step.

[0010] As a further option, the inner wall of the threaded locking ring is provided with an internal thread, which is screwed into the connecting thread of the glass pot body. The upper end of the base is integrally formed with the threaded locking ring, or is ultrasonically welded or connected by a concealed fastener.

[0011] As a further embodiment, the heating device includes a heating element and a heat-conducting plate, with the heating element disposed at the bottom of the heat-conducting plate, and the heat-conducting plate and the heating element sequentially pressed between the bottom surface of the glass pot body and the pusher; or, the heating device is a heating plate.

[0012] As a further embodiment, a sealing ring is provided between the edge of the heat-conducting plate or the top edge of the heating plate and the bottom surface of the threaded locking ring, or between the threaded locking ring and the inner wall of the recessed cavity of the base.

[0013] As a further embodiment, the heat-conducting plate is a microcrystalline plate, the heating element includes a heating wire and a ceramic base, the top of the ceramic base has a concave surface, the heating wire is disposed on the concave surface, the microcrystalline plate is disposed on the top surface of the ceramic base and covers the heating wire, and the upper end of the pusher abuts against the bottom of the ceramic base.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) The base of this utility model is connected to the lower thread of the glass pot body by a threaded locking ring, which makes the connection more convenient. Moreover, the spiral connection process will not exert strong pressure on the outside of the base, avoiding wear of parts. Therefore, the base can be directly used as an exposed part without affecting the appearance of the product. In addition, the heating device is pressed by the pusher, so that the heating device can be close to the bottom surface of the glass pot body, reducing heat loss. At the same time, the spiral surfaces of the connecting threads are tightly attached to each other to form a self-locking mechanism, preventing the threads from loosening and making the connection more reliable.

[0018] (2) A sealing ring is provided between the top edge of the heating device of this utility model (the edge of the heat-conducting plate or the top edge of the heating plate) and the bottom surface of the threaded locking ring, or between the bottom edge and the inner wall of the recessed cavity of the base, so that the glass pot body is isolated from the inside of the base. Even if the glass pot body breaks, the liquid will not flow into the inside of the base, making it safer and more reliable to use. Attached Figure Description
