DETAILED DESCRIPTION

[0049] In order to make the technical problems, technical schemes and beneficial effects to be solved by the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not used to limit the utility model. Embodiments

[0050] As Figure 1 , Figure 2 , Figure 6 , Figure 7 indicated, the utility model provides a kind of anti-overflowing kettle, including kettle body 1, kettle cover 2, heating assembly 3, kettle cover 2 is blocked at the top of kettle body 1, can play the blocking effect to the spout of kettle body 1, heating assembly 3 is set at the bottom of kettle body 1, heating assembly 3 can heat the water in kettle body 1 after being powered.

[0051] As Figure 2 , Figure 8 , Figure 9 indicated, in the embodiment, kettle cover 2 includes upper cover 21, lower cover 22, upper cover 21 is covered and set at the top of lower cover 22, lower cover 22 is provided with several serpentine steam flow channels 221, the first end of serpentine steam flow channel 221 is provided with steam inlet 222, the tail end of serpentine steam flow channel 221 is provided with first steam outlet 223, upper cover 21 is provided with second steam outlet correspondingly, first steam outlet 223 is connected with second steam outlet by steam pipeline 212, when heating, hot water kettle, water vapor enters from steam inlet 222, then goes out through steam pipeline 212.When kettle body 1 is poured, due to the arrangement of serpentine steam flow channel 221, the flow path length of water inside kettle cover 2 can be effectively increased, the time of water source inside kettle body 1 from first steam outlet can be prolonged, so as to prolong the self-protection reaction time of user, so that user has enough time to take countermeasures, prevent hot water from overflowing from spout, to prevent user from being scalded, and then improve the safety performance of hot water kettle.

[0052] As Figure 8 , Figure 9 indicated, in the embodiment, multiple backflow baffle groups 224 are arranged in serpentine steam flow channel 221, to reduce the water leakage amount in the pouring process of hot water kettle.Specifically, backflow baffle group 224 includes first baffle 2241, second baffle 2242, first baffle 2241 and second baffle 2242 are arranged in staggered mode, first baffle 2241 is connected with one side wall of serpentine steam flow channel 221, second baffle 2242 is connected with another side wall opposite to serpentine steam flow channel 221, to form two staggered "blocking arms", can block the water flow entering serpentine steam flow channel 221 from steam inlet 222, reduce the speed of water flow to first steam outlet 223, can greatly reduce the water leakage amount in the pouring process of hot water kettle.

[0053] As shown in Figure 8 , Figure 9 , in the embodiment, the first baffle 2241 and the second baffle 2242 are respectively arranged obliquely on the side wall corresponding to the serpentine steam flow channel 221, the first baffle 2241 and the side wall corresponding to the serpentine steam flow channel 221 form a first blocking space, and the second baffle 2242 and the side wall corresponding to the serpentine steam flow channel 221 form a second blocking space. When the kettle is poured, the water in the kettle body 1 enters the serpentine steam flow channel 221 from the steam inlet 222. Due to the oblique arrangement of the baffles, the water flow is guided into the first blocking space and the second blocking space, thereby achieving the blocking effect of the water flow, further prolonging the time of the water source in the kettle body 1 flowing out from the first steam outlet, allowing the user more time to react and handle, reducing the risk of burns, and further improving the safety performance of the kettle. In addition, the inclination angle of the first baffle 2241 and the side wall corresponding to the serpentine steam flow channel 221 is equal to the inclination angle of the second baffle 2242 and the side wall corresponding to the serpentine steam flow channel 221, which ensures the consistency of the first blocking space and the second blocking space in function and effect, and avoids the problem of uneven water flow or poor blocking effect caused by angle difference.

[0054] As shown in Figure 8 , Figure 9 , in the embodiment, two serpentine steam flow channels 221 are arranged on the lower cover 22, which increases the steam flow path, and the first steam outlets 223 of the two serpentine steam flow channels 221 are located on the same side of the lower cover 22. Therefore, two second steam outlets are arranged on the upper cover 21, and the two second steam outlets are located on the same side of the upper cover 21. The space inside the kettle is fully utilized, and the overall structure of the kettle is more compact, reducing unnecessary space waste.

[0055] As shown in Figures 2 to 5 , Figure 8 , in the embodiment, the lower cover 22 is provided with a sealing ring 4 at the contact part with the inner wall of the kettle body 1, which effectively fills the small gap between the kettle cover 2 and the kettle body 1, preventing leakage of steam, heat or liquid. Secondly, the sealing ring 4 is made of elastic material, which can be designed as a silica gel material that can tightly fit the inner wall of the kettle body 1 to ensure the sealing effect. Of course, in actual design, the material of the sealing ring 4 can be designed according to actual needs.

[0056] As shown in Figures 2 to 5 , Figure 6 , Figure 8As shown, in the present embodiment, the upper cover 21 is provided with a sealing tightness switch 5, which controls the contact area of the sealing ring 4 with the kettle body 1. The sealing tightness switch 5 not only enhances the sealing property between the kettle body 1 and the kettle cover 2, but also increases the friction between the kettle body 1 and the kettle cover 2, effectively preventing the kettle cover 2 from separating from the kettle body 1 due to poor sealing during pouring of the kettle, thereby preventing the kettle cover 2 from falling off the kettle body 1, and further improving the safety performance of the kettle. When the sealing tightness switch 5 is in a closed state, the contact area of the sealing ring 4 with the kettle body 1 is increased, and the sealing performance is further improved. In addition, the lower cover 22 is provided with an annular groove in the circumferential direction, and at least a part of the sealing ring 4 is arranged in the annular groove. The annular groove not only provides a stable mounting position for the sealing ring 4, but also ensures that the sealing ring 4 can uniformly distribute pressure when stressed, avoiding local excessive wear or deformation. At the same time, the design of the annular groove makes the installation and replacement of the sealing ring 4 more convenient, and users can easily replace the sealing ring 4 without disassembling the entire kettle cover 2, thereby reducing maintenance cost and time.

[0057] As shown in Figures 2 to 5 , Figure 6 , Figure 8 In the present embodiment, the sealing tightness switch 5 includes a first connecting portion 51, and a second connecting portion 225 is correspondingly provided on the lower cover 22. The first connecting portion 51 is rotationally connected to the second connecting portion 225 through a connecting shaft 6. When the sealing tightness switch 5 is rotated counterclockwise or clockwise by a certain angle, the first connecting portion 51 pushes the second connecting portion 225 to compress the sealing ring 4, thereby sealing the kettle body 1.

[0058] As shown in Figure 3 , Figure 5 , Figure 6 , Figure 8As shown, specifically, the first connecting part 51 comprises a first base 511, the first base 511 outwardly protrudes to form a first protruding part 512, the second connecting part 225 is correspondingly provided with a second base 2251, the second base 2251 outwardly protrudes to form a second protruding part 2252, the second protruding part 2252 is provided with a receiving groove 2253, at least a part of the first protruding part 512 is embedded in the receiving groove 2253, and the connecting shaft 6 transversely passes through the second protruding part 2252 and the first protruding part 512, so that the first protruding part 512 can rotate around the second protruding part 2252 and the connecting shaft 6, and the tight or loose state of the sealing tightness switch 5 is realized. When the sealing tightness switch 5 is counterclockwise or clockwise rotated to the tight state of the sealing tightness switch 5, the first protruding part 512 abuts against the second protruding part 2252, the first protruding part 512 pushes the second protruding part 2252, so that the lid 2 moves to the side close to the kettle body 1, thereby increasing the contact area of the sealing ring 4 and the kettle body 1, to press the sealing ring 4, tightly connect the lid 2 and the kettle body 1, and prevent hot water from flowing out of the kettle mouth of the kettle body 1; when the sealing tightness switch 5 is counterclockwise or clockwise rotated to the loose state of the sealing tightness switch 5, the first protruding part 512 does not contact the second protruding part 2252, the lid 2 moves to the side away from the kettle body 1, thereby reducing the contact area of the sealing ring 4 and the kettle body 1, reducing the force required to open the lid 2, so that the user can more easily open the lid 2.

[0059] As Figure 8 shown, in the embodiment, the sealing tightness switch 5 further comprises a hand holding part 52 connected with the first connecting part 51, so that the user can intuitively find and operate the sealing tightness switch 5 without groping or searching, improving the convenience of operation. In addition, the upper cover 21 is provided with a mounting groove 211, and the hand holding part 52 is movably arranged in the mounting groove 211, when the sealing tightness switch 5 is in the loose state, the hand holding part 52 is arranged in the mounting groove 211, preventing the sealing tightness switch 5 from being opened by mistake, and improving the overall safety of the kettle. Embodiment

[0060] As Figures 10 to 13As shown, different from the first embodiment, the lower cover 22 of the present embodiment is provided with four sealing units 226, and the plurality of sealing units 226 are annularly distributed in the sealing ring 4. Each of the sealing units 226 is provided with a guide slope 2261, and the four guide slopes 2261 form a guide hole 2262. The sealing tightness switch 5 comprises a push rod group 53 corresponding to the guide hole 2262. When the push rod group 53 moves downward along the axial direction and is inserted into the guide hole 2262, the plurality of sealing units 226 move outward to press the sealing ring 4 against the inner side wall of the kettle body 1, thereby increasing the contact area of the sealing ring 4 with the kettle body 1, and increasing the friction between the kettle body 1 and the kettle cover 2, preventing the kettle cover 2 from being separated from the kettle body 1 when the kettle is poured, avoiding the risk of hot water spilling or scalding due to the separation of the kettle cover 2, and improving the convenience and safety of user experience.

[0061] As shown in Figure 13 , Figure 14 In the present embodiment, the lower shell further comprises a connecting plate 227 provided at the top of the serpentine steam flow channel 221, and the four sealing units 226 are arranged at the top of the connecting plate 227. Each of the sealing units 226 comprises a shell 2263 and a resilient member 2264 arranged in the shell 2263. The connecting plate 227 is provided with a first mounting portion 2271, and the shell 2263 is provided with a second mounting portion 22631. One end of the resilient member 2264 abuts against the first mounting portion 2271, and the other end of the resilient member 2264 abuts against the second mounting portion 22631. The guide slope 2261 is arranged on one side of the shell 2263 close to the push rod group 53. When the push rod group 53 is inserted downward into the guide hole 2262 formed by the four guide slopes 2261, the resilient member 2264 is compressed, and the shell 2263 moves outward to increase the diameter of the sealing ring 4, thereby pressing the sealing ring 4 against the inner side wall of the kettle body 1. When the push rod group 53 is separated upward from the guide hole 2262, the shell 2263 can be moved inward under the resilient action of the resilient member 2264, thereby reducing the diameter of the sealing ring 4, so that the kettle cover 2 can be easily separated from the kettle body 1 when needed to open, without the need for excessive external force or tools, thereby improving the convenience of user operation. In addition, the resilient member 2264 can be designed as a spring, and of course, the structure of the resilient member 2264 can be designed as needed in actual design.

[0062] As shown in Figures 11 to 14As shown, in this embodiment, the push rod assembly 53 includes a first push rod 531, a switching component 532, a connecting member 533, and an elastic member 534. The first push rod 531 is disposed on the upper cover 21 and sleeved on the outside of the switching component 532. The switching component 532 can move up and down along the axial direction of the first push rod 531. The connecting member 533 is disposed at the bottom of the switching component 532. The elastic member 534 is disposed between the switching component 532 and the connecting member 533, with one end of the elastic member 534 abutting against the switching component 532 and the other end of the elastic member 534 abutting against the connecting member 533. When the switching component 532 moves downward along the axial direction of the first push rod 531, the elastic element 534 is compressed. The switching component 532 pushes the connecting piece 533 downward into the guide hole 2262, and the four sealing units 226 move outward, converting the vertical movement of the switching component 532 into the horizontal movement of the sealing units 226, thereby pressing the sealing ring 4 against the inner wall of the pot body 1. When the switching component 532 moves upward along the axial direction of the first push rod 531, the elastic element 534 recovers, the connecting piece 533 is pulled out from the guide hole 2262, and the four sealing units 226 move inward to their original positions, reducing the contact area between the sealing ring 4 and the pot body 1, thereby reducing the friction between the pot body 1 and the lid 2, making it easier for the lid 2 to separate from the pot body 1. In this embodiment, the pressing and releasing of the sealing ring 4 can be achieved by the up-and-down movement of the switching component 532 in conjunction with the left-and-right movement of the sealing units 226, making the operation simple and quick. In addition, the elastic element 534 can be designed as a spring. Of course, in actual design, the structure of the elastic element 534 can be designed according to actual needs.

A guide post 53211 is correspondingly disposed on the second push rod 5321, and the guide post 53211 slides along the guide groove 5311. A first limiting post 5312 is formed between two adjacent guide grooves 5311. The third push rod 5322 is disposed at the bottom of the second push rod 5321, and a plurality of second limiting posts 53221 corresponding one-to-one with the first limiting posts 5312 are provided circumferentially on the third push rod 5322. The second push rod 5321 pushes the third push rod 5322 downward, and the second limiting post 53221 engages with the first limiting post 5312, so that the connector 533 is inserted into the guide hole 2262. In addition, a button 535 is provided on the top of the second push rod 5321, which makes it easy to press the second push rod 5321 and move it downward, reducing the difficulty of operation.

[0064] like Figure 11 , Figures 13 to 16As shown, in the embodiment, the bottom of the second push rod 5321 is circumferentially provided with a push tooth 53212 corresponding to the guide column 53211, the end of each first limiting column 5312 in the first push rod 531 is provided with a first inclined surface 5313, and the end of each second limiting column 53221 of the third push rod 5322 is provided with a second inclined surface 53222 matched with the first inclined surface 5313. The push tooth 53212 of the second push rod 5321 pushes the third push rod 5322 downward along the second inclined surface 53222 of the third push rod 5322, so that the third push rod 5322 rotates around its axis, thereby switching the third push rod 5322 between the locked state and the unlocked state, and further inserting or pulling out the connecting piece 533 from the guide hole 2262.
