Description

Technical Field

[0001] The present invention relates to the technical field of kettles, and more specifically, to a kettle for preventing water spillage.

Background Art

[0002] In daily life and in the preparation of various beverages, kettles are commonly used as heating containers, and their safety and practicality have always been widely noted. If the kettle suddenly falls over or an unexpected situation occurs, the water in the kettle body can easily spill out from the steam holes on the kettle cover. This not only wastes the hot water but also poses a risk of scalding the user.

[0003] To solve the above problems, conventional kettles are usually sealed by gravity members such as a method using a counterweight. When the kettle body falls over, the steam holes are sealed by the gravity of the counterweight, preventing the liquid in the kettle from spilling along the steam holes. However, when the temperature inside the kettle rises, the liquid in the kettle evaporates continuously to generate steam, and the pressure inside the kettle continues to rise. Since there is no other pressure relief device, the kettle is prone to explosion, causing scalding to the user and having low safety.

[0004] The above defects need to be solved urgently.

[0027] To further clarify the technical problems, technical solutions, and advantageous effects that this invention aims to solve, the invention will be described in more detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are used solely for the purpose of illustrating the invention and are not intended to limit it. [Examples]

[0028] As shown in Figures 1, 2, 6, and 7, the present invention provides a spill-proof kettle. The spill-proof kettle includes a kettle body 1, a kettle cover 2, and a heating assembly 3, the kettle cover 2 being sealed on the top of the kettle body 1 and sealing the opening of the kettle body 1, and the heating assembly 3 being provided on the bottom of the kettle body 1 and capable of heating the water inside the kettle body 1 after power is supplied.

[0029] As shown in Figures 2, 8, and 9, in this embodiment, the kettle cover 2 includes an upper cover 21 and a lower cover 22. The upper cover 21 covers the top of the lower cover 22, and the lower cover 22 is provided with a plurality of meandering steam passages 221, with steam inlets 222 at the ends of the meandering steam passages 221 and a first steam outlet 223 at the ends of the meandering steam passages 221. A second steam outlet is correspondingly located on the upper cover 21, and the first steam outlet 223 is connected to the second steam outlet via a steam pipe 212. When the kettle is heated, steam enters through the steam inlets 222 and exits through the steam pipe 212. By providing a meandering steam channel 221, if the kettle body 1 tips over, the length of the water channel inside the kettle cover 2 can be effectively increased, extending the time that water inside the kettle body 1 flows out of the steam hole. This extends the user's self-defense reaction time, allowing them sufficient time to take measures to prevent hot water from spilling from the kettle's opening, thus preventing burns and improving the safety performance of the kettle.

[0030] As shown in Figures 8 and 9, in this embodiment, a group of backflow baffles 224 is provided within the meandering steam passage 221 to reduce the amount of water leakage when the kettle is tipped over. Specifically, the backflow baffle group 224 includes a first baffle 2241 and a second baffle 2242. The first baffle 2241 and the second baffle 2242 are arranged alternately, with the first baffle 2241 connected to one side wall of the meandering steam passage 221 and the second baffle 2242 connected to the other side wall on the opposite side of the meandering steam passage 221. This forms two alternate "blocking arms" that block the flow of water entering the meandering steam passage 221 from the steam inlet 222, reduce the velocity of the water flow to the first steam outlet 223, and significantly reduce the amount of water leakage when the kettle is tipped over.

[0031] As shown in Figures 8 and 9, in this embodiment, the first baffle 2241 and the second baffle 2242 are each positioned at an inclination with respect to the side wall corresponding to the meandering steam passage 221, forming a first isolation space between the first baffle 2241 and the side wall corresponding to the meandering steam passage 221, and a second isolation space is formed between the second baffle 2242 and the side wall corresponding to the meandering steam passage 221. When the kettle tips over, the water in the kettle body 1 enters the meandering steam passage 221 from the steam inlet 222, and because the baffles are positioned at an inclination, the water flow is guided into the first and second isolation spaces, blocking the water flow and further extending the time it takes for the water in the kettle body 1 to flow out of the steam hole. This gives the user more time to react to the situation, reduces the risk of burns, and further improves the safety performance of the kettle. Furthermore, the inclination angle of the first baffle 2241 with respect to the side wall corresponding to the meandering steam flow path 221 is equal to the inclination angle of the second baffle 2242 with respect to the side wall corresponding to the meandering steam flow path 221. This ensures consistency in the function and effect of the first and second blocking spaces, and avoids problems such as uneven water flow and reduced blocking effect due to angle differences.

[0032] As shown in Figures 8 and 9, in this embodiment, the lower cover 22 is provided with two meandering steam passages 221 to increase the steam flow path, the first steam outlets 223 of the two meandering steam passages 221 are located on the same side of the lower cover 22, and the upper cover 21 has two corresponding second steam outlets, both located on the same side of the upper cover 21. This makes full use of the space inside the kettle, makes the overall structure of the kettle more compact, and reduces unnecessary waste of space.

[0033] As shown in Figures 2 to 5 and Figure 8, in this embodiment, a seal ring 4 is provided at the contact point between the lower cover 22 and the inner wall of the kettle body 1, effectively filling the minute gap between the kettle cover 2 and the kettle body 1 and preventing leakage of steam, heat, or liquid. The seal ring 4 is made of an elastic material and may be designed to be made of a silicone material, thereby ensuring a tight seal by adhering firmly to the inner wall of the kettle body 1. Of course, in actual design, the material of the seal ring 4 can be designed according to the actual needs.

[0034] As shown in Figures 2-5, 6, and 8, in this embodiment, the upper cover 21 is provided with a sealing control switch 5. By controlling the contact area between the seal ring 4 and the kettle body 1 using the sealing control switch 5, not only is the airtightness between the kettle body 1 and the kettle cover 2 increased, but the frictional force between the kettle body 1 and the kettle cover 2 is also increased. This effectively prevents the airtightness from decreasing and the kettle cover 2 from separating from the kettle body 1 when the kettle tips over, preventing the kettle cover 2 from falling off the kettle body 1 and further improving the safety performance of the kettle. When the sealing control switch 5 is in the closed position, the contact area between the seal ring 4 and the kettle body 1 is increased, further improving the airtightness. In addition, an annular groove is provided in the circumferential direction of the lower cover 22, and at least a part of the seal ring 4 is provided within the annular groove. The annular groove not only provides a stable mounting position for the seal ring 4, but also evenly distributes the pressure when the seal ring 4 is subjected to force, avoiding localized excessive wear and deformation. At the same time, the annular groove design facilitates the installation and replacement of the seal ring 4, allowing users to easily replace the seal ring 4 without removing the entire kettle cover 2, thereby reducing maintenance costs and time.

[0035] As shown in Figures 2 to 5, 6 and 8, in this embodiment, the sealing control switch 5 includes a first connection part 51, and a second connection part 225 is correspondingly positioned on the lower cover 22. The first connection part 51 is rotatably connected to the second connection part 225 via a connecting shaft 6. When the sealing control switch 5 is rotated by a certain angle counterclockwise or clockwise, that is, when the sealing control switch 5 is closed, the first connection part 51 pushes the second connection part 225, pressing the seal ring 4 against it and sealing the kettle body 1.

[0036] As shown in Figures 3, 5, 6, and 8, specifically, the first connecting portion 51 includes a first base portion 511, the first base portion 511 protruding outward to form a first convex portion 512, the second connecting portion 225 has a corresponding second base portion 2251, the second base portion 2251 protruding outward to form a second convex portion 2252, the second convex portion 2252 is provided with a housing groove 2253, at least a part of the first convex portion 512 is embedded in the housing groove 2253, the connecting shaft 6 passes across the second convex portion 2252 and the first convex portion 512, thereby the first convex portion 512 rotates around the connecting shaft 6 of the second convex portion 2252, and the sealing control switch 5 can be opened and closed. When the sealing control switch 5 is rotated counterclockwise or clockwise to the closed position, the first protrusion 512 comes into contact with the second protrusion 2252, and the first protrusion 512 pushes the second protrusion 2252, moving the kettle cover 2 closer to the kettle body 1, increasing the contact area between the seal ring 4 and the kettle body 1, pressing the seal ring 4 and firmly connecting the kettle cover 2 and the kettle body 1, preventing hot water from flowing out of the opening of the kettle body 1. When the sealing control switch 5 is rotated counterclockwise or clockwise to the open position, the first protrusion 512 does not come into contact with the second protrusion 2252, and the kettle cover 2 moves away from the kettle body 1, reducing the contact area between the seal ring 4 and the kettle body 1, and reducing the force required to open the kettle cover 2, thereby allowing the user to open the kettle cover 2 more easily.

[0037] As shown in Figure 8, in this embodiment, the sealing control switch 5 further includes a handgrip portion 52 connected to the first connection portion 51, which allows the user to intuitively find and operate the sealing control switch 5 without feeling around or searching for it, thereby improving ease of operation. In addition, the upper cover 21 is provided with a mounting groove 211, and the handgrip portion 52 is movably mounted within the mounting groove 211. When the sealing control switch 5 is in the open state, the handgrip portion 52 is positioned within the mounting groove 211, preventing the sealing control switch 5 from being opened by accidental contact, thereby improving the overall safety of the kettle. [Examples]

[0038] As shown in Figures 10 to 13, the differences from Embodiment 1 are as follows. The lower cover 22 of this embodiment is provided with four sealing portions 226, and the multiple sealing portions 226 are distributed in an annular manner within the sealing ring 4. Each sealing portion 226 is provided with a guide slope 2261, and the four guide slopes 2261 surround the seal so as to form a guide hole 2262. The sealing control switch 5 includes a group of push rods 53, which correspond to a guide hole 2262. When the group of push rods 53 moves downward along its axial direction and is inserted into the guide hole 2262, the multiple sealing parts 226 move outward, pressing the sealing ring 4 against the inner wall of the kettle body 1. This increases the contact area between the sealing ring 4 and the kettle body 1, increasing the frictional force between the kettle body 1 and the pot cover 2. This prevents the kettle cover 2 from falling off the kettle body 1 when the kettle tips over, avoiding the risk of hot water splashing and burns caused by the kettle cover 2 falling off, and improving the convenience and safety of the user experience.

[0039] As shown in Figures 13 and 14, in this embodiment, the lower cover further includes a connecting plate 227, which is provided at the top of the meandering steam passage 221, and four sealing portions 226 are provided at the top of the connecting plate 227, each sealing portion 226 including a housing 2263 and a repulsion member 2264, the repulsion member 2264 is provided inside the housing 2263, a first mounting portion 2271 is provided on the connecting plate 227, a second mounting portion 22631 is provided inside the housing 2263, one end of the repulsion member 2264 abuts against the first mounting portion 2271, and the other end of the repulsion member 2264 abuts against the second mounting portion 22631. The guide slope 2261 is provided on the side of the housing 2263 closer 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 rebound member 2264 is compressed, causing the housing 2263 to move outward, expanding the diameter of the seal ring 4 and pressing it against the inner wall of the kettle body 1. When the push rod group 53 is separated upward from the guide hole 2262, the rebound action of the rebound member 2264 drives the housing 2263 to move inward, reducing the diameter of the seal ring 4, and allowing the kettle cover 2 to be easily separated from the kettle body 1 without requiring excessive external force or tools when it is necessary to open the kettle cover 2, thereby improving the convenience of operation for the user. The rebound member 2264 may also be designed as a spring, and of course, in the actual design, the structure of the rebound member 2264 can be designed according to the needs.

[0040] As shown in Figures 11 to 14, in this embodiment, the push rod group 53 includes a first push rod 531, a switching assembly 532, a connecting member 533, and an elastic member 534. The first push rod 531 is provided on the upper cover 21 and is fitted to the outside of the switching assembly 532, and the switching assembly 532 is movable up and down along the axial direction of the first push rod 531. The connecting member 533 is provided at the bottom of the switching assembly 532, and the elastic member 534 is provided between the switching assembly 532 and the connecting member 533, with one end of the elastic member 534 in contact with the switching assembly 532 and the other end of the elastic member 534 in contact with the connecting member 533. As the switching assembly 532 moves downward along the axial direction of the first push rod 531, the elastic member 534 is compressed, causing the switching assembly 532 to push the connecting member 533 downward into the guide hole 2262, the four sealing portions 226 move outward, converting the vertical movement of the switching assembly 532 into the horizontal movement of the sealing portions 226, pressing the seal ring 4 against the inner wall of the kettle body 1. As the switching assembly 532 moves upward along the axial direction of the first push rod 531, the elastic member 534 returns to its original position, the connecting member 533 is pulled out of the guide hole 2262, and the four sealing portions 226 move inward back to their original positions, reducing the contact area between the seal ring 4 and the kettle body 1, thereby reducing the frictional force between the kettle body 1 and the pot cover 2, making it easier to separate the kettle cover 2 from the kettle body 1. In this embodiment, the seal ring 4 can be tightened or loosened by moving the switching assembly 532 up and down and the seal portion 226 left and right, making the operation simple and quick. The elastic member 534 may also be designed as a spring, and of course, in the actual design, the structure of the elastic member 534 can be designed according to the needs.

[0041] As shown in Figures 11, 13 to 16, in this embodiment, the switching assembly 532 includes a second push rod 5321 and a third push rod 5322. The first push rod 531 is provided with a movable cavity, at least a portion of the second push rod 5321 is provided within the movable cavity, and a plurality of guide grooves 5311 are provided on the inner wall of the movable cavity at circumferential intervals, and a guide column 53211 is positioned correspondingly to the second push rod 5321, and the guide column 53211 slides along the guide grooves 5311. A first position limiting column 5312 is formed between two adjacent guide grooves 5311, a third push rod 5322 is provided at the bottom of the second push rod 5321, and a plurality of second position limiting columns 53221 are provided at circumferential intervals around the third push rod 5322, with one-to-one correspondences to the first position limiting column 5312. The second push rod 5321 pushes the third push rod 5322 downward, causing the second position limiting columns 53221 to engage with the first position limiting column 5312, thereby inserting the connecting member 533 into the guide hole 2262. Additionally, a button 535 is provided at the top of the second push rod 5321 to make it easier to push down the second push rod 5321 and reduce the difficulty of operation.

[0042] As shown in Figures 11, 13 to 16, in this embodiment, push teeth 53212 are provided circumferentially at the bottom of the second push rod 5321, and the push teeth 53212 correspond one-to-one with the guide column 53211. A first inclined surface 5313 is provided at the end of each first position limiting column 5312 in the first push rod 531, and a second inclined surface 53222 is provided at the end of each second position limiting column 53221 of the third push rod 5322, which coincides with the first inclined surface 5313. The push teeth 53212 of the second push rod 5321 push the third push rod 5322 downward along the second inclined surface 53222 of the third push rod 5322, thereby causing the third push rod 5322 to rotate around its axis, allowing the third push rod 5322 to switch between a locked state and an open state, enabling the connecting member 533 to be inserted into or withdrawn from the guide hole 2262. The interaction between the push teeth 53212 of the second push rod 5321 and the second position limiting column 53221 enables the rotation function of the third push rod 5322 and the switching between the locked state and the open state. The operation method is simple and intuitive, making it easy for the user to operate.

[0043] As shown in Figures 11, 13 to 16, specifically, the second push rod 5321 is pushed down, and the push teeth 53212 of the second push rod 5321 push against the second position limiting column 53221 corresponding to the third push rod 5322, moving the third push rod 5322 downward until it is completely out of the moving cavity of the first push rod 531. The third push rod 5322 moves to the bottom position of the push teeth 53212 corresponding to the second push rod 5321 via the second inclined surface 53222 of the second position limiting column 53221, thereby rotating the third push rod 5322 relative to the first push rod 531. At the same time, the action of the elastic member 534 pushes the third push rod 5322 and the second push rod 5321 upward. Since the guide column 53211 of the second push rod 5321 is slidable along the guide groove 5311 of the first push rod 531, the second push rod 5321 enters the movable cavity of the first push rod 531. At this time, the second inclined surface 53222 of the third push rod 5322 slides along the corresponding first inclined surface 5313 of the first push rod 531. As a result, the second position limiting column 53221 of the third push rod 5322 engages with the first position limiting column 5312 corresponding to the first push rod 531, limiting the position of the third push rod 5322 and locking the third push rod 5322. This locks the connecting member 533 into the guide hole 2262, pressing the seal ring 4 against the kettle body 1 and preventing the water inside the kettle body 1 from spilling due to tipping.

[0044] As shown in Figures 11, 13 to 16, when the third push rod 5322 is switched to the open position, the second push rod 5321 is pushed down again, and the push teeth 53212 of the second push rod 5321 push the second position limiting column 53221 corresponding to the third push rod 5322, moving the third push rod 5322 downward until it is completely separated from the moving cavity of the first push rod 531, and the third push rod 5322 moves through the second inclined surface 53222 of the second position limiting column 53221 to the bottom position of the push teeth 53212 corresponding to the second push rod 5321, thereby the third push rod 5322 moves away from the first push rod As the third push rod 5322 rotates relative to the first push rod 531, the second position limiting column 53221 of the third push rod 5322 aligns with the guide column 53211 of the second push rod 5321. The action of the elastic member 534 pushes the third push rod 5322 and the second push rod 5321 upward, causing the second position limiting column 53221 of the third push rod 5322 and the guide column 53211 of the second push rod 5321 to enter the guide groove 5311 corresponding to the first push rod 531. This causes the connecting member 533 to be pulled out of the guide hole 2262, reducing the contact area between the seal ring 4 and the kettle body 1, and facilitating the separation of the kettle cover 2 and the kettle body 1.

[0045] As shown in Figures 15 and 16, in this embodiment, the guide groove 5311 of the first push rod 531 includes alternating deep grooves 53111 and shallow grooves 53112, with the depth of the deep groove 53111 being greater than the depth of the shallow groove 53112, and the first position limiting column 5312 is provided between the deep groove 53111 and the shallow groove 53112. The guide column 53211 of the second push rod 5321 includes alternating thick column 532111 and thin column 532112, with the thickness of the thick column 532111 being greater than the thickness of the thin column 532112, the thick column 532111 sliding along the deep groove 53111, and the thin column 532112 sliding along the shallow groove 53112. The alternating arrangement of deep grooves 53111 and shallow grooves 53112, and the corresponding thick and thin columns 532111 and 532112, enables more precise guidance and positioning, resulting in more stable sliding of the second push rod 5321 along the first push rod 531, thereby improving the stability of the assembly.
