[0016] Compared with the prior art, this utility model provides a ceramic kettle with good heat preservation effect, which has the following beneficial effects:

[0017] 1. This ceramic kettle with good heat preservation effect, when the lid is placed on the kettle body, the weight of the lid itself causes the lid to exert pressure deformation on the hollow sealing sleeve, so that the inner side of the hollow sealing sleeve can fit between the top edge and the inner edge, and the outer side can fit between the top edge and the outer edge. This can improve the sealing between the kettle body and the lid from both the inside and outside, so as to improve the heat preservation effect of the ceramic kettle.

[0018] 2. In this ceramic kettle with good heat retention, the hot steam generated by the hot water in the kettle cavity rises. Some of the steam is directly discharged through the vent, while some of the steam condenses into liquid water upon contact with the lid. This liquid water flows along the surface of the lid cavity into the water storage tank. The liquid water inside the water storage tank flows and collects at the vent port, blocking it and preventing the hot steam in the kettle cavity from continuing to escape through the vent, thus further improving the heat retention effect of the ceramic kettle.

In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] Please see Figures 1-5 This utility model provides a ceramic kettle with good heat preservation effect, including a kettle body 1, a handle 2 fixed on the surface of the kettle body 1, a kettle lid 3 at the top of the kettle body 1, a heat preservation coating 4 on the surface of the kettle body 1 and the kettle lid 3, a kettle cavity 5 inside the kettle body 1, a top edge 6 at the top of the kettle body 1, a kettle knob 7 at the top of the kettle lid 3, a connecting groove 8 at the bottom edge of the kettle lid 3, an inner edge 9 on the inner side of the connecting groove 8, an outer edge 10 on the outer side of the connecting groove 8, and a heat preservation structure between the kettle body 1 and the kettle lid 3.

[0027] The heat preservation structure includes a hollow sealing sleeve 11, which is fixed inside the connecting groove 8. The bottom of the lid 3 has a lid cavity 12, and the bottom of the lid cavity 12 has a water storage tank 13. The water storage tank 13 has an exhaust hole 14 inside, and liquid water 15 is placed inside the water storage tank 13. By pouring hot water into the kettle cavity 5 and then covering it with the lid 3, the hot water can be kept warm and stored. When the lid 3 is placed on the kettle body 1, it can seal the kettle body 1 and the lid 3 to improve the heat preservation effect of the ceramic kettle.

[0028] Furthermore, the height of the side of the water tank 13 near the vent 14 is lower than the height of the side away from the vent 14, and the two sides of the water tank 13 are at different heights. The water tank 13 is lower near the vent 14 so that the liquid water 15 inside the water tank 13 can collect at the port of the vent 14 and block the vent 14.

[0029] Furthermore, one end of the vent 14 passes through the lid 3 and extends out of the lid 3, while the other end of the vent 14 is connected to the water storage tank 13, so that the hot air in the pot cavity 5 can be discharged through the vent 14 to reduce the pressure inside the pot cavity 5.

[0030] Furthermore, the cover cavity 12 is umbrella-shaped, which facilitates the flow of liquid water 15 generated by surface liquefaction into the water storage tank 13 through the umbrella-shaped cover cavity 12.

[0031] Furthermore, the middle part of the upper surface of the hollow sealing sleeve 11 is bonded and fixed to the middle part of the inner top surface of the connecting groove 8, and the middle part of the hollow sealing sleeve 11 is bonded and fixed to the middle part of the top surface of the connecting groove 8. However, the two ends of the hollow sealing sleeve 11 are not fixed, so that the two ends of the hollow sealing sleeve 11 can be more easily deformed.

[0032] Furthermore, the top edge 6 is located between the inner edge 9 and the outer edge 10. The top edge 6, the inner edge 9, and the outer edge 10 are all annular, which facilitates the compression of both ends of the hollow sealing sleeve 11 through the inner edge 9 and the outer edge 10, so that the two ends of the hollow sealing sleeve 11 are fitted between the top edge 6 and the inner edge 9 and between the top edge 6 and the outer edge 10.

[0033] Furthermore, the body 1, handle 2, and top edge 6 are fired as a single piece, and the lid 3, knob 7, inner edge 9, and outer edge 10 are fired as a single piece, which helps to improve the strength of the body 1, handle 2, and top edge 6, as well as the strength of the lid 3, knob 7, inner edge 9, and outer edge 10.

[0034] Furthermore, the heat-insulating coating 4 includes a nano-hollow ceramic microsphere coating and an inorganic polymer coating. The nano-hollow ceramic microsphere coating is applied to the body 1 and the lid 3, and the inorganic polymer coating is applied to the nano-hollow ceramic microsphere coating. The nano-hollow ceramic microsphere coating and the inorganic polymer coating have excellent heat-insulating properties, so as to improve the heat-insulating effect of the ceramic kettle.

[0035] In use, hot water is poured into the kettle cavity 5 and then the lid 3 is placed on top to keep the hot water warm. When the lid 3 is placed on the kettle body 1, the hollow sealing sleeve 11 fits against the top edge 6. Due to the weight of the lid 3, it exerts pressure on the hollow sealing sleeve 11, causing it to deform. The deformed hollow sealing sleeve 11 is then limited from the inside by the inner edge 9 and from the outside by the outer edge 10. This allows the inner side of the hollow sealing sleeve 11 to fit between the top edge 6 and the inner edge 9, and the outer side to fit between the top edge 6 and the outer edge 10. This improves the seal between the kettle body 1 and the lid 3 from both the inside and outside, preventing hot air from escaping from the kettle cavity 5 and thus improving the heat retention effect of the ceramic kettle. In addition, after the kettle body 1 and the lid 3 are sealed, the hot air generated by the hot water in the kettle cavity 5 will rise, and some of the hot air will escape through the exhaust fan. The steam is discharged directly through the vent 14. During this process, the pressure in the kettle cavity 5 is reduced first. After some hot air comes into contact with the lid cavity 12, which has a lower temperature at the bottom of the lid 3, the water vapor condenses into liquid water 15 due to the temperature difference between the water vapor and the lid cavity 12. The liquid water 15 flows along the surface of the lid cavity 12 into the water storage tank 13. Because there is a height difference between the two sides of the water storage tank 13, and the side closer to the vent 14 is lower, the liquid water 15 inside the water storage tank 13 flows and collects at the port of the vent 14. When the water level in the water storage tank 13 rises, it will block the port of the vent 14, preventing the hot air in the kettle cavity 5 from continuing to be discharged through the vent 14. Therefore, the liquid water 15 generated by the hot air coming into contact with the lid 3 will be stored in the water storage tank 13, and the liquid water 15 stored in the water storage tank 13 will block the vent 14 to prevent the hot air from escaping, so as to further improve the heat preservation effect of the ceramic kettle.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
