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 the preparation of various beverages, kettles are commonly used as heating containers, and their safety and practicality have always been widely concerned. When the kettle suddenly falls or an unexpected situation occurs, the water in the kettle body can easily spill out from the steam hole 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 weight. When the kettle body falls, the steam hole is sealed by the gravity of the weight, preventing the liquid in the kettle from spilling along the steam hole. 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 the user to be scalded and having low safety.

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

Modes for Carrying Out the Invention

[0027] In order to more clearly illustrate the technical problems to be solved, the technical solutions, and the advantageous effects of the present invention, the present invention will be described in more detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used for explaining the present invention and are not intended to limit the present invention.

Embodiment

[0028] As shown in FIGS. 1, 2, 6, and 7, the present invention provides a kettle for preventing water spillage. The kettle for preventing water spillage includes a kettle body 1, a kettle cover 2, and a heating assembly 3. The kettle cover 2 is sealed to the top of the kettle body 1 to seal the opening of the kettle body 1, and the heating assembly 3 is provided at the bottom of the kettle body 1 and can heat the water in the kettle body 1 after being energized.

[0029] As shown in FIGS. 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. A plurality of meandering steam channels 221 are provided in the lower cover 22. A steam inlet 222 is provided at the tip of the meandering steam channel 221, and a first steam outlet 223 is provided at the end of the meandering steam channel 221. A second steam outlet is correspondingly arranged on the upper cover 21. The first steam outlet 223 is connected to the second steam outlet via a steam pipe 212. When the kettle is heated, water vapor enters from the steam inlet 222 and exits through the steam pipe 212. By providing the meandering steam channel 221, when the kettle body 1 topples over, the flow path length of the water in the kettle cover 2 can be effectively increased, and the time for the water in the kettle body 1 to flow out from the steam holes can be extended. Therefore, the user's self-defense reaction time can be extended, enabling the user to take sufficient time to prevent the hot water from spilling from the opening of the kettle, preventing burns, and as a result, improving the safety performance of the kettle.

[0030] As shown in FIGS. 8 and 9, in this embodiment, a plurality of countercurrent baffle groups 224 are provided in the meandering steam channel 221 to reduce the water leakage amount during the toppling of the kettle. Specifically, the countercurrent 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. The first baffle 2241 is connected to one side wall of the meandering steam channel 221, and the second baffle 2242 is connected to the other side wall on the opposite side of the meandering steam channel 221. Thereby, two alternating "blocking arms" are formed to block the flow of water entering the meandering steam channel 221 from the steam inlet 222, reduce the flow rate of water to the first steam outlet 223, and can significantly reduce the water leakage amount during the toppling of the kettle.

[0031] As shown in FIGS. 8 and 9, in this embodiment, the first baffle 2241 and the second baffle 2242 are each disposed obliquely with respect to the side wall corresponding to the meandering steam flow path 221. A first cut-off space is formed between the first baffle 2241 and the side wall corresponding to the meandering steam flow path 221, and a second cut-off space is formed between the second baffle 2242 and the side wall corresponding to the meandering steam flow path 221. When the kettle falls over, the water in the kettle body 1 enters the meandering steam flow path 221 from the steam inlet 222. Since the baffles are disposed obliquely, the flow of water is guided into the first cut-off space and the second cut-off space, the flow of water is blocked, and the time for the water in the kettle body 1 to flow out from the steam holes is further extended. Thereby, the user has more time to react and take measures in response to the situation, the risk of scalding is reduced, and the safety performance of the kettle is further improved. Also, 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, thereby ensuring the consistency of the functions and effects of the first cut-off space and the second cut-off space, and avoiding problems such as non-uniform water flow and reduced cut-off effect due to the angle difference.

[0032] As shown in FIGS. 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. Two second steam outlets are correspondingly arranged on the upper cover 21, and the two second steam outlets are located on the same side of the upper cover 21. Thereby, the space inside the kettle is fully utilized, the overall structure of the kettle is made more compact, and waste of unnecessary space is reduced.

[0033] As shown in FIGS. 2 to 5 and FIG. 8, in this embodiment, a sealing ring 4 is provided at the contact portion 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 to prevent leakage of steam, heat, or liquid. The sealing ring 4 is made of an elastic material and may be designed to be made of a silicon material, thereby ensuring a tight seal by closely adhering to the inner wall of the kettle body 1. Of course, in an actual design, the material of the sealing ring 4 can be designed according to actual needs.

[0034] As shown in FIGS. 2 to 5, FIG. 6 and FIG. 8, in this embodiment, a sealing control switch 5 is provided on the upper cover 21. By controlling the contact area between the sealing ring 4 and the kettle body 1 with the sealing control switch 5, not only the sealing performance between the kettle body 1 and the kettle cover 2 is enhanced, but also the frictional force between the kettle body 1 and the kettle cover 2 is increased, effectively preventing the sealing performance from decreasing and the kettle cover 2 from separating from the kettle body 1 when the kettle is overturned, 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 state, the contact area between the sealing ring 4 and the kettle body 1 is increased to further improve the sealing performance. Further, an annular groove is provided in the circumferential direction of the lower cover 22, and at least a part of the sealing ring 4 is provided in the annular groove. The annular groove not only provides a stable mounting position for the sealing ring 4, but also evenly disperses the pressure when the sealing ring 4 receives a force, avoiding local excessive wear and deformation. At the same time, the design of the annular groove facilitates the installation and replacement of the sealing ring 4. The user can easily replace the sealing ring 4 without removing the entire kettle cover 2, thus reducing the maintenance cost and time.

[0035] As shown in FIGS. 2 to 5, FIG. 6 and FIG. 8, in this embodiment, the sealing control switch 5 includes a first connection portion 51, and a second connection portion 225 is correspondingly arranged on the lower cover 22. The first connection portion 51 is rotatably connected to the second connection portion 225 via a connection shaft 6. When the sealing control switch 5 is rotated counterclockwise or clockwise by a certain angle, that is, when the sealing control switch 5 is in the closed state, the first connection portion 51 presses the second connection portion 225 to press the sealing ring 4, thereby sealing the kettle body 1.

[0036] As shown in FIGS. 3, 5, 6 and FIG. 8, specifically, the first connection portion 51 includes a first base portion 511. The first base portion 511 protrudes outward to form a first convex portion 512. A second base portion 2251 is correspondingly arranged on the second connection portion 225. The second base portion 2251 protrudes outward to form a second convex portion 2252. A receiving groove 2253 is provided in the second convex portion 2252. At least a part of the first convex portion 512 is embedded in the receiving groove 2253. The connection shaft 6 passes through the second convex portion 2252 and the first convex portion 512 transversely. Thereby, the first convex portion 512 can rotate around the connection shaft 6 of the second convex portion 2252, and the opening and closing of the sealing control switch 5 can be realized. When the sealing control switch 5 is rotated counterclockwise or clockwise to the closed state, the first convex portion 512 abuts against the second convex portion 2252, and the first convex portion 512 presses the second convex portion 2252 to move the kettle cover 2 closer to the kettle body 1, increasing the contact area between the sealing ring 4 and the kettle body 1, pressing the sealing ring 4 to firmly connect the kettle cover 2 and the kettle body 1, and 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 state, the first convex portion 512 does not contact the second convex portion 2252, and the kettle cover 2 moves away from the kettle body 1. Therefore, the contact area between the sealing ring 4 and the kettle body 1 is reduced, reducing the force required to open the kettle cover 2. Thereby, the user can more easily open the kettle cover 2.

[0037] As shown in Fig. 8, in this embodiment, the sealing control switch 5 further includes a handgrip portion 52 connected to the first connection portion 51. Thereby, the user can intuitively find and operate the sealing control switch 5 without groping or searching for it, improving the convenience of operation. Further, an attachment groove 211 is provided in the upper cover 21, and the handgrip portion 52 is movably provided in the attachment groove 211. When the sealing control switch 5 is in the open state, the handgrip portion 52 is provided in the attachment groove 211, thus preventing the sealing control switch 5 from being opened by accidental contact and improving the safety of the entire kettle.

Embodiment

[0038] As shown in Figs. 10 to 13, the differences from Embodiment 1 are as follows. Four seal portions 226 are provided on the lower cover 22 of this embodiment. The plurality of seal portions 226 are annularly distributed within the seal ring 4. Each seal portion 226 is provided with a guide slope 2261, and the four guide slopes 2261 surround to form a guide hole 2262. The sealing control switch 5 includes a push rod group 53. The push rod group 53 corresponds to the guide hole 2262. When the push rod group 53 moves downward along its axial direction and is inserted into the guide hole 2262, the plurality of seal portions 226 move outward to press the seal ring 4 against the inner wall of the kettle body 1, increasing the contact area between the seal ring 4 and the kettle body 1, increasing the frictional force between the kettle body 1 and the pot cover 2, preventing the kettle cover 2 from falling off the kettle body 1 when the kettle falls, avoiding the risk of hot water splashing and scalding due to the falling off of the kettle cover 2, and improving the convenience and safety of the user experience.

[0039] As shown in FIGS. 13 and 14, in this embodiment, the lower cover further includes a connection plate 227. The connection plate 227 is provided at the top of the serpentine steam flow path 221. Four seal portions 226 are provided at the top of the connection plate 227. Each seal portion 226 includes a housing 2263 and a resilient member 2264. The resilient member 2264 is provided inside the housing 2263. A first mounting portion 2271 is provided on the connection plate 227, and a second mounting portion 22631 is provided inside the housing 2263. 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 provided on the side of the housing 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, the housing 2263 moves outward to expand the diameter of the seal ring 4, and presses against the inner wall of the kettle body 1. When the push rod group 53 is separated upward from the guide hole 2262, due to the resilient action of the resilient member 2264, the housing 2263 is driven to move inward, reducing the diameter of the seal ring 4. When it is necessary to open the kettle cover 2, the kettle cover 2 can be easily separated from the kettle body 1 without excessive external force or tools, improving the convenience of the user's operation. Also, the resilient member 2264 may be designed as a spring. Of course, in actual design, the structure of the resilient member 2264 can be designed according to needs.

[0040] As shown in FIGS. 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. The first push rod 531 is fitted outside 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. One end of the elastic member 534 abuts against the switching assembly 532, and the other end of the elastic member 534 abuts against the connecting member 533. When the switching assembly 532 moves downward along the axial direction of the first push rod 531, the elastic member 534 is compressed, and the switching assembly 532 pushes the connecting member 533 and inserts it downward into the guide hole 2262, and the four seal portions 226 move outward, converting the vertical movement of the switching assembly 532 into the horizontal movement of the seal portions 226, and pressing the seal ring 4 against the inner wall of the kettle body 1. When the switching assembly 532 moves upward along the axial direction of the first push rod 531, the elastic member 534 is restored, the connecting member 533 is pulled out from the guide hole 2262, and the four seal portions 226 move inward and return 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 and 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 the up and down movement of the switching assembly 532 and the left and right movement of the seal portions 226, and the operation is simple and rapid. Further, the elastic member 534 may be designed as a spring. Of course, in actual design, the structure of the elastic member 534 can be designed according to needs.

[0041] As shown in FIGS. 11, 13 to 16, in this embodiment, the switching assembly 532 includes a second push rod 5321 and a third push rod 5322. A moving cavity is provided in the first push rod 531, and at least a part of the second push rod 5321 is provided in the moving cavity. A plurality of guide grooves 5311 are provided at intervals in the circumferential direction on the inner wall of the moving cavity. A guide post 53211 is correspondingly arranged on the second push rod 5321, and the guide post 53211 slides along the guide groove 5311. A first position limiting post 5312 is formed between two adjacent guide grooves 5311. The third push rod 5322 is provided at the bottom of the second push rod 5321. A plurality of second position limiting posts 53221 corresponding one-to-one to the first position limiting posts 5312 are provided at intervals in the circumferential direction of the third push rod 5322. The second push rod 5321 pushes the third push rod 5322 to move downward, and the second position limiting post 53221 engages with the first position limiting post 5312 to insert the connecting member 533 into the guide hole 2262. Further, 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 FIGS. 11, 13 to 16, in this embodiment, push teeth 53212 are provided in the circumferential direction at the bottom of the second push rod 5321, and the push teeth 53212 correspond one-to-one to the guide posts 53211. At the end of each first position-limiting post 5312 in the first push rod 531, a first inclined surface 5313 is provided, and at the end of each second position-limiting post 53221 of the third push rod 5322, a second inclined surface 53222 that coincides with the first inclined surface 5313 is provided. 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, whereby the third push rod 5322 rotates about its axis, and the third push rod 5322 can switch between a locked state and an open state, and the connecting member 533 can be inserted into or pulled out from the guide hole 2262. The interaction between the push teeth 53212 of the second push rod 5321 and the second position-limiting posts 53221 realizes the rotation function of the third push rod 5322 and realizes the switching between the locked state and the open state. The operation method is simple and intuitive, and easy for the user to operate.

[0043] As shown in FIGS. 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 the second position limiting post 53221 corresponding to the third push rod 5322, and the third push rod 5322 is moved downward until it completely exits from 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 through the second inclined surface 53222 of the second position limiting post 53221. Thereby, the third push rod 5322 rotates with respect to the first push rod 531. At the same time, due to the action of the elastic member 534, the third push rod 5322 and the second push rod 5321 are pushed upward. Since the guide post 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 moving cavity of the first push rod 531. At this time, the second inclined surface 53222 of the third push rod 5322 slides along the first inclined surface 5313 of the corresponding first push rod 531. Thereby, the second position limiting post 53221 of the third push rod 5322 engages with the first position limiting post 5312 corresponding to the first push rod 531, restricting the position of the third push rod 5322 to lock the third push rod 5322, locking the connecting member 533 and inserting it into the guide hole 2262, pressing the sealing ring 4 against the kettle body 1 to prevent the water in the kettle body 1 from spilling due to tipping.

[0044] As shown in FIGS. 11 and 13 to 16, when the third push rod 5322 switches to the open state, 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 post 53221 corresponding to the third push rod 5322, and the third push rod 5322 is moved downward until it is completely separated from the movement 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 through the second inclined surface 53222 of the second position limiting post 53221. Thereby, the third push rod 5322 rotates relative to the first push rod 531. At this time, the second position limiting post 53221 of the third push rod 5322 is aligned with the guide post 53211 of the second push rod 5321.
