[0024] To make the technical solution, purpose and advantages of this utility model clearer, the following explanation is given in conjunction with the accompanying drawings and embodiments.

[0025] As attached Figures 1 to 3 As shown, this utility model discloses a kettle structure, which includes a kettle shell 1, an inner liner 10 for water storage inside the kettle shell 1, and a top cover 2 that can be attached to the upper side of the inner liner 10. A water outlet 11 is provided on the kettle shell 1, and a water passage connects the water outlet 11 to the inner liner 10.

[0026] A positioning bracket 21 is provided on the lower side of the upper cover 2. A steam inlet 22 is provided on the positioning bracket 21, and a plug 23 is installed on the steam inlet 22. An exhaust structure 3 is installed on the upper side of the positioning bracket 21. An exhaust inlet 31 is provided on the exhaust structure 3 corresponding to the position of the steam inlet 22. The positioning bracket 21 guides the plug 23 to make a limited displacement between the steam inlet 22 and the exhaust inlet 31. An exhaust outlet 32 ​​is provided on the upper side of the exhaust structure 3. The positions of the exhaust inlet 31 and the exhaust outlet 32 ​​are staggered, and a buffer space is formed in the exhaust structure 3. A steam outlet 24 is provided on the upper side of the upper cover 2. The positions of the exhaust outlet 32 ​​and the steam outlet 24 are correspondingly provided.

[0027] The application principle of its installation structure is as follows:

[0028] By guiding the displacement of the plug 23 through the positioning bracket 21, when the kettle structure is tilted, the plug 23, under the action of gravity or the driving force of some water flowing into the kettle towards the steam inlet 22, will block the water source at the steam outlet 31. A small portion of the water flowing towards the steam inlet 22 may flow out from the steam outlet 31 before the plug 23 blocks the water source. Therefore, by setting the steam outlet 32 ​​and the steam inlet 31 to be staggered in position, the water flowing into the steam outlet structure 3 can be buffered in the buffer space of the steam outlet structure 3, preventing the water from flowing directly out of the steam outlet structure 3.

[0029] The preferred embodiment of the exhaust structure 3 is configured as follows:

[0030] The exhaust structure 3 includes an exhaust base 33 and an exhaust connector 34 mounted on the upper side of the exhaust base 33. The exhaust inlet 31 is provided on the exhaust base 33, and the exhaust outlet 32 ​​is provided on the exhaust connector 34.

[0031] Specifically, the exhaust substrate 33 includes a base plate 331, with an exhaust inlet 31 located at the center of the front side of the base plate 331. An exhaust cylinder 332 extends vertically upward from the outer periphery of the exhaust inlet 31. An inclined guide surface 334 extends downward from the outer periphery toward the exhaust inlet 31 on the upper side of the base plate 331. The upper end of the exhaust cylinder 332 is closed, and an exhaust opening 333 is provided facing forward.

[0032] The exhaust pipe 34 includes a front section 341 located on the front side and a rear section 342 located on the rear side. The rear section 342 is vertically higher than the front section 341. The exhaust outlet 32 ​​is located at the upper end of the rear section 342. An exhaust baffle 343 extends vertically downward between the front section 341 and the rear section 342. The upper end of the exhaust pipe 332 is spaced from the top end of the front section 341.

[0033] Furthermore, as a preferred structural arrangement of the positioning bracket 21, the positioning bracket 21 includes a bracket body 211 in the shape of an inverted cone. The upper side of the bracket body 211 is open, the lower end of the bracket body 211 is closed, and the outer periphery is hollowed out to form the steam inlet 22. The plug body 23 is in the shape of an inverted frustum, and the outer periphery of the plug body 23 is adapted to the inner diameter of the bracket body 211.

[0034] The combined application principle of the positioning bracket 21 structure and the exhaust structure 3 is as follows:

[0035] Under normal conditions, the plug 23 is positioned at the lower end of the support body 211 under the influence of gravity. When there is hot water in the kettle, steam enters through the steam inlet 22 with a perforated outer periphery, bypasses the plug 23, and enters the steam exhaust structure 3 through the steam exhaust inlet 31 above. The steam enters and exits from the front of the steam exhaust structure 3 through the steam exhaust opening 333, then passes through the buffer space formed by the front section 341 and the rear section 342, and finally exits from the steam exhaust outlet 32 ​​towards the steam outlet 24 for external steam discharge. During this process, due to the tortuous channel design of the buffer space, the steam liquefies into water droplets within the steam exhaust structure 3. The water droplets are guided by the inclined guide surface 334 back to the steam exhaust inlet 31 and then fall back to the steam inlet 22, returning to the inner liner 10.

[0036] The upper cover 2 is provided with a cover plate corresponding to the position of the exhaust outlet 32. A plurality of steam outlets 24 are provided on the outer periphery of the cover plate. The diameter of the steam outlets 24 is smaller than the inner diameter of the exhaust outlet 32. Thus, the steam concentrated at the exhaust outlet 32 ​​can be discharged externally through the small-sized steam outlets 24.

[0037] When the kettle is tilted, water in the inner liner 10 enters the positioning bracket 21 through the steam inlet 22, impacting the plug 23. Under the impact of the water influx, the plug 23 is guided along the positioning bracket 21 and blocks the steam inlet 31. Some of the water that enters the steam structure 3 through the steam inlet 31 before the plug 23 blocks the water will be buffered in the buffer space (most of which is located in the gap between the top of the front section 341 and the top of the steam hole, separated by the steam baffle 343). Then, when the kettle is placed upright again, the water in the buffer space is guided back to the inner liner 10 by the inclined guide surface 334.

[0038] In a preferred embodiment, the steam inlet 22 includes a first inlet 212 located on the front side of the support body 211 and a second inlet 213 located on the rear side of the support body 211, wherein the size of the first inlet 212 is larger than the size of the second inlet 213; and a plurality of support blocks 214 are provided on the inner side of the support body 211, which are protruding inward along the direction of the conical sidewall of the support body 211.

[0039] By setting the size difference of the first inlet 212, a certain pressure difference can be generated at this position, which can better guide the steam out. And by setting the support block 214, the steam can be fed into the inside of the support body 211 from the first inlet 212 and the second inlet 213, and then flow through the gap between the support block 214 and the plug body 23 to the exhaust inlet 31.

[0040] A water-slowing baffle 4 for buffering residual water is provided between the inner tank 10 and the upper cover 2; a plurality of steam holes 41 are provided in the center of the water-slowing baffle 4, and a water storage space 42 is provided in the lower outer periphery of the water-slowing baffle 4; a frustum-shaped lifting part 43 is provided in the upper concave and raised center of the water-slowing baffle 4, and the steam holes 41 are provided in the upper end face of the lifting part 43.

[0041] When the kettle is tilted, a large amount of water rushes directly towards the upper lid 2. The high water pressure may cause water to leak out from the gap between the upper lid 2 and the inner liner 10. The structure of the water-slowing baffle 4 effectively prevents water from rushing directly towards the upper lid 2, and the surging water or steam under normal conditions will be controlled and discharged from the steam vent 41.

[0042] The above description is only a preferred embodiment of the present utility model. For those skilled in the art, modifications can still be made to the embodiments without departing from the implementation principle of the present utility model, and the corresponding modifications should also be considered within the protection scope of the present utility model.
