Description

A tilting spill prevention mechanism and container

[0001] This application claims priority to Chinese patent applications filed on November 26, 2024, with application numbers 202422890214.2 and 202411704526.8, both entitled "A Tilting and Overflow Prevention Mechanism and Container", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of overflow prevention technology, and in particular to a tilting overflow prevention mechanism and container. Background Technology

[0003] A kettle is a type of container that is frequently used as an everyday item. Most kettles currently have steam channels, vents, and spouts that are directly connected to the outside. When the kettle is tilted, the water inside will quickly flow out through these channels, posing a risk of scalding the user and wetting the surrounding environment (potentially affecting other electrical appliances). Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a spill prevention mechanism and container to solve the risk of water flowing out of the kettle after it is tipped over, which may scald the user or wet the environment (affecting other electrical appliances).

[0005] To achieve the above-mentioned technical objectives, this application provides a tilting and overflow prevention mechanism, including a main body, a first counterweight ball, and a second counterweight ball;

[0006] The main body of the mechanism is provided with a first communication port and a second communication port on opposite sides;

[0007] The main body of the mechanism is provided with a first channel and a second channel that are independent of each other;

[0008] The two ends of the first channel are respectively connected to the first connection port and the second connection port;

[0009] The first channel has a first initial position between its two ends;

[0010] The first counterweight ball is installed in the first channel;

[0011] When the main body of the mechanism is in a non-tilting state, the first counterweight ball remains in the first initial position;

[0012] When the main body of the mechanism is tilted, the first counterweight ball can roll along the first channel to the first connecting port to block the first connecting port or roll to the second connecting port to block the second connecting port.

[0013] The two ends of the second channel are respectively connected to the first connection port and the second connection port;

[0014] The second channel has a second initial position between its two ends;

[0015] The second counterweight ball is installed in the first channel;

[0016] The second counterweight ball remains in the second initial position when the main body of the mechanism is in a non-tilting state;

[0017] When the main body of the mechanism is tilted, the second counterweight ball can roll along the second channel to the first connecting port to block the first connecting port or roll to the second connecting port to block the second connecting port.

[0018] The first channel and the second channel are not perfectly symmetrically arranged, or the weights of the first counterweight ball and the second counterweight ball are inconsistent, or the heights of the first initial position and the second initial position are inconsistent, so that the first counterweight ball and the second counterweight ball cannot reach the first connection port or the second connection port at the same time.

[0019] Furthermore, the main body of the mechanism includes a support base and a faceplate;

[0020] The cover is mounted on one side of the support.

[0021] The first communication port is located on the other side of the support.

[0022] The second communication port is opened on the cover;

[0023] The first channel and the second channel are disposed in the support.

[0024] Furthermore, the projections of the first channel and the second channel from one side of the support to the other side are arranged in a figure-eight shape.

[0025] Furthermore, the first channel and the second channel are separated by a flange;

[0026] The portion located above the flange forms a connecting area between the first channel and the second channel.

[0027] Furthermore, the cover is provided with flanged portions distributed around its circumference;

[0028] The outer circumferential surface of the support seat is provided with a first step portion for the flange portion to be inserted.

[0029] Furthermore, both the first and second counterweight balls are metal balls.

[0030] Furthermore, a first guide portion is provided on the inner side of the first connecting port;

[0031] A second guide portion is provided on the inner side of the second communication port.

[0032] This application also discloses a container, including a container body and the aforementioned spill prevention mechanism;

[0033] The first or second connecting port of the tilting and overflow prevention mechanism is connected to the steam port of the container body.

[0034] Furthermore, the first or second connecting port is connected to the steam port via a connecting pipe.

[0035] Furthermore, the tipping and overflow prevention mechanism is provided with a second step portion on one side of the first or second connecting port for one end of the connecting pipe to be inserted.

[0036] As can be seen from the above technical solutions, the tipping overflow prevention mechanism designed in this application, through the design of a channel connected to the connecting port, and then installing a counterweight ball that can roll along the channel in the channel, can roll along the channel to the position of the first or second connecting port to block the first or second connecting port when tipping occurs, thus achieving the tipping overflow prevention effect. More importantly, this application adopts a dual-channel / dual-counterweight ball design. When tipping is made towards the direction of the first counterweight ball (second counterweight ball), even if the first counterweight ball (second counterweight ball) happens to be unable to roll to block the first or second connecting port due to its own weight being equal to its own pressure on the first channel (second channel), the second counterweight ball (first counterweight ball) can still roll normally to block the first or second connecting port, ensuring the tipping sealing effect. This avoids the situation where a single connecting port cannot be blocked when tipping to the opposite side of a single connecting port. It also employs a dual-port design to avoid the situation where a single-port design would fail to roll to block the corresponding single port when tilting towards the side facing that port, thus ensuring a proper spill seal. In summary, the spill prevention mechanism designed in this application achieves a 360° omnidirectional anti-spill effect, effectively solving the problems of scalding users and wetting the environment (affecting other electrical appliances) due to spillage.

[0037] As can be seen from the above technical solutions, the container designed in this application has its steam port connected to the aforementioned tilting and overflow prevention mechanism, thereby achieving the effect of tilting and overflow prevention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0049] This application discloses a tilting mechanism and container to prevent overflow.

[0050] Please refer to Figures 1 to 5. One embodiment of a spill prevention mechanism provided in this application includes:

[0051] The main body of the mechanism 1, the first counterweight ball 21 and the second counterweight ball 22, the first counterweight ball 21 and the second counterweight ball 22 have the same size and weight / different weight.

[0052] The main body 1 has a first connecting port 31 and a second connecting port 32 on opposite sides. In actual use, the first connecting port 31 and the second connecting port 32 can be aligned or not aligned. The specific design can be flexibly changed according to actual needs without restriction.

[0053] The main body 1 is provided with a first channel 41 and a second channel 42 that are independent of each other. The first channel 41 and the second channel 42 are located on both sides of the first connecting port 31 or the second connecting port 32.

[0054] The two ends of the first channel 41 are connected to the first connecting port 31 and the second connecting port 32 respectively. The first channel 41 has a first initial position between its two ends. The first initial position is the lowest part of the channel section of the first channel 41. In order to better fix the first counterweight ball 31 in the first initial position, a groove structure can be made at this position to fix the first counterweight ball 31. When tilting, it can slide out from the groove.

[0055] The first counterweight ball 21 is installed in the first channel 41. When the main body 1 of the mechanism is in a non-tilting state, the first counterweight ball 21 remains in the first initial position. As shown in Figures 4 and 5, when the main body 1 of the mechanism is in a tilting state, the first counterweight ball 21 can roll along the first channel 41 to the first connecting port 31 to block the first connecting port 31 or roll to the second connecting port 32 to block the second connecting port 32, so that water and air cannot flow out through the first connecting port 31 or the second connecting port 32, thus playing a sealing role.

[0056] The two ends of the second channel 42 are respectively connected to the first connecting port 31 and the second connecting port 32; the second channel 42 has a second initial position between its two ends; the second initial position is the channel segment with the lowest height of the second channel 42; similarly, in order to better fix the second counterweight ball 32 in the second initial position, a groove structure can be made at this position to fix the second counterweight ball 32, which can slide out from the groove when tilted.

[0057] The second counterweight ball 22 is installed in the first channel 41. When the main body 1 of the mechanism is in a non-tilting state, the second counterweight ball 22 remains in the second initial position. As shown in Figures 4 and 5, when the main body 1 of the mechanism is in a tilting state, the second counterweight ball 22 can roll along the second channel 42 to the first connecting port 31 to block the first connecting port 31 or roll to the second connecting port 32 to block the second connecting port 32.

[0058] The first channel 41 and the second channel 42 are not perfectly symmetrically arranged, or the weights of the first counterweight ball 21 and the second counterweight ball 22 are inconsistent, or the heights of the first initial position and the second initial position are inconsistent, so that the first counterweight ball 21 and the second counterweight ball 22 cannot reach the first connecting port 31 or the second connecting port 32 at the same time.

[0059] The first channel 41 and the second channel 42 are not completely symmetrically arranged, which means that the first channel 41 and the second channel 42 are different in terms of layout / structure, and are not completely mirror images or equivalent to each other. In this application, the first channel 41 and the second channel 42 are symmetrical in layout, but their own curvature / slope are different (or the roughness in their own channels is inconsistent).

[0060] In one scenario, the first channel 41 and the second channel 42 are not perfectly symmetrical, but the first counterweight ball 31 and the second counterweight ball 32 have the same weight, and the first initial position and the second initial position have the same height. This ensures that the first counterweight ball 21 and the second counterweight ball 22 cannot reach the first connecting port 31 or the second connecting port 32 at the same time.

[0061] In another scenario, the weights of the first counterweight ball 31 and the second counterweight ball 32 are different, but the first channel 41 and the second channel are completely symmetrical, and the heights of the first initial position and the second initial position are the same, ensuring that the first counterweight ball 21 and the second counterweight ball 22 cannot reach the first connecting port 31 or the second connecting port 32 at the same time.

[0062] In another scenario, the heights of the first and second initial positions are different, but the weights of the first and second counterweight balls 31 and 32 are the same, and the first and second channels 41 are completely symmetrical. This ensures that the first and second counterweight balls 21 and 22 cannot reach the first or second connecting port 31 or 32 simultaneously. (The first and second initial positions are located in their respective first and second channels 41 and 42, near the second connecting port 32).

[0063] As can be seen from the above technical solutions, the tipping overflow prevention mechanism designed in this application, through the design of a channel connected to the connecting port, and then installing a counterweight ball that can roll along the channel in the channel, can roll along the channel to the position of the first connecting port 31 or the second connecting port 32 to block the first connecting port 31 or the second connecting port 32 when tipping occurs, thus achieving the tipping overflow prevention effect. More importantly, this application adopts a dual-channel / dual-counterweight ball design. When tipping is made towards the direction of the first counterweight ball 21 (second counterweight ball 22), even if the first counterweight ball 21 (second counterweight ball 22) cannot roll to block the first connecting port 31 or the second connecting port 32 due to its own weight being equal to its own pressure on the first channel 41 (second channel 42), the second counterweight ball 22 (first counterweight ball 21) can still roll normally to block the first connecting port 31 or the second connecting port 32, ensuring the tipping sealing effect. This avoids the situation where a single connecting port cannot be blocked when tipping to the opposite side of a single connecting port. It also employs a dual-port design to avoid the situation where a single-port design would fail to roll to block the corresponding single port when tilting towards the side facing that port, thus ensuring a proper spill seal. In summary, the spill prevention mechanism designed in this application achieves a 360° omnidirectional anti-spill effect, effectively solving the problems of scalding users and wetting the environment (affecting other electrical appliances) due to spillage.

[0064] The above is an embodiment of a tipping and overflow prevention mechanism provided in this application. The following is an embodiment of a tipping and overflow prevention mechanism provided in this application. Please refer to Figures 1 to 5 for details.

[0065] Based on the solution of Embodiment 1 above:

[0066] Furthermore, the first channel 41 and the second channel 42 are inclined as a whole (the whole has a slope setting) to ensure that the first counterweight ball 31 and the second counterweight ball 32 can slide smoothly along their respective channels when the mechanism is tilted.

[0067] In addition, the first channel 41 and the second channel 42 can be straight channels, curved channels, S-shaped channels, etc., and can be designed in a different way according to actual needs without restriction.

[0068] As shown in Figure 3, the projections of the first channel 41 and the second channel 42 of this application onto the side of the support 11 are arranged in a figure-eight shape. This distribution design makes the structure more compact and further improves the smoothness of the counterweight ball when tilting. Under this distribution design, the internal structure cross section of the main body 1 of the mechanism can be designed in the shape of a red heart.

[0069] Furthermore, the first channel 41 and the second channel 42 of this application can be designed as U-shaped channels (the cross-section of the channel is U-shaped) or circular channels (the cross-section of the channel is circular). Of course, they are not limited to the above designs. Those skilled in the art can make changes according to actual needs without restriction.

[0070] Furthermore, as shown in Figure 3, the first channel 41 and the second channel 42 are separated by a flange 112, and the portion above the flange 112 forms a connecting area between the first channel 41 and the second channel 42. This design further utilizes the shared area of ​​the first channel 41 and the second channel 42 to make the overall mechanism more compact.

[0071] If the size of the connected region is larger than the diameter of the first counterweight ball 21 and the second counterweight ball 22, then the length of the first channel 41 and the second channel 42 should be designed to be smaller than the diameter of the two counterweight balls to ensure that two counterweight balls cannot coexist in the channel and that the two counterweight balls can return to their respective channels normally when reset to the normal state.

[0072] Of course, the first channel 41 and the second channel 42 can be completely independent (not connected) or partially connected. The specific design can be changed according to actual needs, without any restrictions.

[0073] Furthermore, as shown in Figures 1 and 2, the design of the main body 1 includes a support base 11 and a cover 12.

[0074] The cover 12 is installed on one side of the support 11, the first connecting port 31 is opened on the other side of the support 11, the second connecting port 32 is opened on the cover 12, and the first channel 41 and the second channel 42 are provided in the support 11.

[0075] Furthermore, the faceplate 12 is detachably connected to the support base 11, which facilitates the maintenance of the first channel 41 and the second channel 42 as well as the maintenance of the first counterweight ball 21 and the second counterweight ball 22.

[0076] Furthermore, as shown in Figure 1, the cover 12 is provided with flanged portions 121 distributed around its circumference, and the outer circumferential surface of the support 11 is provided with a first stepped portion 111 into which the flanged portions 121 are engaged. Specifically, the cover 12 and the support 11 can be connected and fixed by interference fit or by snap-fit, and there is no specific limitation.

[0077] A sealing ring can also be provided between the flange 121 and the step to improve the connection sealing.

[0078] Furthermore, in order to achieve a certain weight, the first counterweight ball 21 and the second counterweight ball 22 are metal balls. Specifically, the first counterweight ball 21 and the second counterweight ball 22 are steel balls, or they can be ceramic balls or other ball structures with a certain weight, without limitation.

[0079] Furthermore, as shown in Figure 1, a first guide portion 311 is provided inside the first connecting port 31, and a second guide portion 321 is provided inside the second connecting port 32. The first guide portion 311 and the second guide portion 321 can guide the first counterweight ball 21 and the second counterweight ball 22, so that the first counterweight ball 21 or the second counterweight ball 22 can enter and exit more smoothly from the position blocking the first connecting port 31 and the second connecting port 32.

[0080] The two ends of the first channel 41 and the second channel 42 in this application can be smoothly connected to the first connecting port 31 and the second connecting port 32, respectively. As shown in Figures 1 and 3, the first channel 41 and the second channel 42 are directly and smoothly connected to the first guide portion 311. For easier processing, the second connecting port 32 on the cover 12 is not designed to be directly and smoothly connected to the first channel 41 and the second channel 42. However, the distance between the contour edge formed by the first channel 41 and the second channel 42 on the inner side of the cover 12 and the edge of the second guide portion is less than the radius of the first counterweight ball 31 and the second counterweight ball 32, ensuring that the first counterweight ball 31 and the second counterweight ball 32 cannot stay on the inner side of the cover 12, so that they can slide smoothly into the second guide portion. Depending on actual needs, the second guide portion 321 can also be smoothly connected to the first channel 41 and the second channel 42, and there is no specific limitation.

[0081] As shown in Figure 6, this application also discloses a container, including a container body and a spill prevention mechanism. The container body can be a kettle, thermos flask, or other container structure, and there are no specific limitations.

[0082] The first connecting port 31 or the second connecting port 32 of the tilting anti-overflow mechanism is connected to the steam port of the container body.

[0083] Furthermore, the first connecting port 31 or the second connecting port 32 is connected to the steam port via the connecting pipe 5.

[0084] Furthermore, the overflow prevention mechanism has a second step on one side of the first connecting port 31 or the second connecting port 32 for inserting one end of the connecting pipe 5.

[0085] As shown in Figures 1 and 6, taking the tipping and overflow prevention mechanism with a second step at the first connecting port 31 as an example, one end of the connecting pipe 5 can be inserted into the second step and tightly connected to the tipping and overflow prevention mechanism through interference fit. A sealing ring can also be added between them to improve the connection sealing.

[0086] The above provides a detailed description of a spill prevention mechanism and container provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
