Description

Technical Field

[0001] The present application belongs to the field of kitchen appliances, and specifically relates to a splash-proof electric water bottle. Background Art

[0002] Electric kettles are small and easy to move, and are widely used in homes and offices. As a commonly used electrical appliance, the safety of their use is particularly important.

[0003] An electric thermos usually includes a container with an inner cavity and a lid that is buckled on the top of the container. Liquid is heated in the inner cavity, and steam is generated in the inner cavity during the heating process. Therefore, it is necessary to design an exhaust structure on the lid to exhaust the steam generated by the heated liquid in the inner cavity of the electric thermos. Electric thermos in the prior art usually have one or more holes on the lid to exhaust the steam, and the steam is discharged directly from the inner cavity through the holes. However, during the heating process of the electric thermos, boiling water is also likely to boil along the exhaust channel to the holes and overflow from the lid, which causes a cleaning burden to the user, and may even cause burns if used carelessly, posing a safety hazard.

[0004] In order to prevent boiling water from overflowing, the existing electric thermos has a circuitous air guide channel on the kettle cover. For example, the patent with application number 202020029239.2 discloses a cover body and an electric thermos, wherein the cover body includes an upper cover body and an inner cover installed on the bottom surface of the upper cover body, the inner cover is provided with a steam inlet channel, the upper cover body is provided with a steam outlet channel displaced from the steam inlet channel, and a steam guide channel connecting the steam inlet channel and the steam outlet channel is also provided between the inner cover and the upper cover body, and the kinetic energy of the boiling water is consumed through the circuitous channel, thereby reducing the probability of boiling water overflowing. However, due to the long path of the steam guide channel, the boiling water that has not splashed to the outside is easily retained and accumulated in the steam guide channel, affecting the steam circulation speed and the exhaust effect, and the inner cover and the upper cover body are an integrated structure, which is not convenient for disassembling the cover body, and it is impossible to clean between the upper cover body and the inner cover, resulting in scale inside the cover body, breeding bacteria, and even affecting the water quality safety in the electric thermos. Utility Model Content

[0005] The present application provides a splash-proof electric thermos, which solves the problem of boiling water overflowing from the electric thermos when discharging steam, increasing the cleaning burden on users and even causing burns, as well as the problem of liquid accumulation inside the exhaust channel, generating scale and breeding bacteria, affecting water quality safety.

[0006] The technical solution adopted in this application is:

[0007] A splash-proof electric hot water bottle comprises a container with an inner cavity and a pot cover buckled on the top of the container, the pot cover is provided with a mounting opening, a venting component for connecting the outside with the inner cavity is detachably provided at the mounting opening, the venting component comprises an adapter and a steam pressure plate, the adapter and the steam pressure plate are butt-jointed to form an exhaust channel, a sealing component is clamped and fixed between the adapter and the steam pressure plate, the exhaust channel comprises a first channel, a plurality of first water retaining ribs are provided in the first channel, and at least part of two adjacent first water retaining ribs are axially staggered.

[0008] This solution forms an exhaust channel by setting an adapter to connect with the steam pressure plate. The exhaust channel can be formed while the kettle lid is assembled. The steps are simple and easy to operate. By setting a plurality of first water retaining ribs, boiling water sprayed from the inner cavity is blocked in the exhaust channel. The boiling water falls back after being blocked by the water retaining ribs, thereby preventing the boiling water from surging up along the exhaust channel to the installation port and then splashing to the outside. At least two adjacent first water retaining ribs are axially staggered to achieve the blocking of boiling water over the entire radial length in the first channel. The staggered first water retaining ribs allow the steam to pass through the first channel in a circuitous manner, avoiding steam burns caused by rapid steam outflow. By setting the first water retaining ribs, the cleaning burden and scalding risk caused by boiling water overflow can be avoided while achieving steam discharge.

[0009] Since the breathable component is detachably arranged at the installation opening, it is convenient to disassemble and clean the breathable component from the installation opening, thereby avoiding liquid accumulation in the exhaust channel formed by the breathable component and affecting the exhaust effect, and at the same time avoiding scale accumulation inside the breathable component, which leads to poor exhaust, bacterial growth and even affects the quality of drinking water. This is beneficial to ensuring the cleanliness of the inside of the breathable component, achieving good exhaust and anti-boiling effects, improving user experience and improving the safety of the electric thermos.

[0010] In a preferred implementation of a splash-proof electric thermos, the exhaust channel also includes a second channel extending vertically and a third channel extending laterally, and steam flows from the inner cavity to the outside through the second channel, the third channel and the first channel in sequence, and the first channel and the second channel are laterally staggered.

[0011] By setting the second channel and the third channel, the flow path of steam and boiling water is extended, and the second channel is further set to extend vertically and the third channel is further set to extend horizontally, and the steam flow path passes through the vertical second channel, the horizontal third channel and the first channel in sequence. The flow path is tortuous, which can reduce the boiling water overflowing from the inner cavity to the first channel, and the exhaust channel path is relatively long, which is beneficial to reducing the potential energy of boiling water upwelling to the installation port and reducing the overflow of boiling water; the first channel and the second channel are set to be horizontally offset to avoid the exhaust channel directly connecting the inner cavity with the installation port, thereby preventing boiling water from directly overflowing from the inner cavity to the installation port, and the tortuous exhaust channel is used to block the boiling water to prevent boiling water from splashing from the installation port to the outside.

[0012] In a preferred implementation of the splash-proof electric hot water bottle, the adapter is provided with a second water retaining rib extending toward the third channel.

[0013] By setting a second water retaining rib toward the third channel, boiling water in the third channel is blocked. Since the third channel is arranged horizontally and the first channel and the second channel are horizontally offset, the second water retaining rib blocks the boiling water splashed from the second channel to the third channel, so that part of the boiling water cannot continue to surge along the third channel, further preventing the boiling water from overflowing.

[0014] In a preferred implementation of the splash-proof electric water bottle, the projection of the second water retaining rib on the horizontal plane falls on the outside of the second channel.

[0015] By setting the second water retaining rib in the lateral direction, the second water retaining rib will not directly face the channel opening of the second channel, thereby blocking the boiling water splashed out from the channel opening of the second channel when flowing along the third channel, causing the boiling water to fall back into the second channel, thereby improving the effect of the second water retaining rib and effectively reducing the boiling water splashing from the third channel to the first channel.

[0016] In a preferred implementation of the splash-proof electric hot water bottle, a bottom surface of the third channel close to the first channel is provided with a return surface, and the return surface extends downwardly and obliquely from one side of the first channel to one side of the second channel.

[0017] Since the third channel is located between the first channel and the second channel, on the one hand, boiling water splashes from the second channel to the third channel, and on the other hand, the boiling water blocked by the first water retaining rib falls back to the third channel. Since the liquid in the inner cavity of the electric thermos always maintains a boiling temperature when the water vapor is discharged and boiling water is generated, the continuously generated boiling water and the boiling water that is blocked and falls back are concentrated in the third channel. By setting the reflux surface, the speed at which the boiling water in the third channel flows back to the second channel is accelerated, and the boiling water falling and reflux effect in the exhaust channel is improved, thereby avoiding liquid accumulation in the exhaust channel, resulting in poor exhaust effect, and even scaling and bacterial growth. This is beneficial to keeping the interior of the exhaust channel clean and achieving a good exhaust and anti-boiling effect.

[0018] In a preferred implementation of the splash-proof electric hot water bottle, the angle θ between the return surface and the horizontal plane satisfies: 5°≤θ≤45°.

[0019] By limiting the angle between the return surface and the horizontal plane, the boiling water return effect of the return surface is improved. If the angle between the return surface and the horizontal plane is too small, the boiling water flowing along the return surface will flow slowly, and may gather on the return surface, which is not conducive to the rapid return of boiling water. If the angle between the return surface and the horizontal plane is too large, the internal space of the third channel will be small, which is not conducive to extending the boiling water flow path, and is not conducive to the third channel and the first channel and the second channel to cooperate to achieve the anti-splashing effect of boiling water. At the same time, by strengthening the guiding effect of the return surface to avoid the situation of liquid retention and accumulation, it is conducive to ensuring the exhaust effect of the exhaust channel and preventing the problem of liquid accumulation causing scale and breeding bacteria.

[0020] In a preferred implementation of the splash-proof electric water bottle, a third water retaining rib extending laterally is provided on the sealing member close to the first channel, and a projection of the third water retaining rib on the horizontal plane is located in the first channel.

[0021] The blocking effect on boiling water is enhanced by arranging a third water retaining rib on the sealing component. The third water retaining rib is laterally arranged at a position close to the first channel. When boiling water enters the first channel, the third water retaining rib is first used to block the boiling water, so as to reduce the amount of boiling water entering the first channel and further improve the anti-splashing effect. At the same time, since the third water retaining rib is formed by extending part of the sealing component, it is beneficial to enhance the sealing effect between the adapter and the steam pressure plate.

[0022] In a preferred implementation of the splash-proof electric water bottle, the third water retaining rib is axially offset from the adjacent first water retaining rib, and the projection of the third water retaining rib on the horizontal plane partially overlaps with the projection of the adjacent first water retaining rib on the horizontal plane.

[0023] By arranging the third water retaining rib to be axially offset with the adjacent first water retaining rib, the boiling water first passes through the third water retaining rib for partial blocking, and the unblocked boiling water is blocked by the first water retaining rib which is different from the third water retaining rib in radial position after passing through the height of the third water retaining rib, so as to achieve multi-position blocking for the boiling water just when it enters the first channel, and the projection of the third water retaining rib on the horizontal plane partially overlaps with the projection of the adjacent first water retaining rib on the horizontal plane, thereby further improving the comprehensive blocking effect on the boiling water, causing the boiling water to fall back, which is beneficial to improving the anti-splashing effect.

[0024] In a preferred implementation of a splash-proof electric thermos, the adapter includes a top plate and a limiting rib extending downward from the top plate, the steam compression plate is provided with an annular rib adapted to the limiting rib, and the seal includes a first sealing section clamped between the limiting rib and the side wall of the annular rib and a second sealing section clamped between the top plate and the top wall of the annular rib.

[0025] By setting the first sealing section and the second sealing section, a multi-directional sealing effect is achieved between the adapter and the steam pressure plate, thereby preventing steam or boiling water from entering the connection between the adapter and the steam pressure plate, ensuring the structural stability of the adapter and the steam pressure plate, thereby ensuring the structural functional stability of the exhaust channel, and always achieving the discharge of steam and the splash prevention effect of boiling water.

[0026] In a preferred implementation of the splash-proof electric hot water bottle, a limiting section extending downward is provided at the extended end of the second sealing section, a limiting groove is formed between the limiting section and the first sealing section, and the top end of the annular rib is inserted into the limiting groove.

[0027] By setting a downwardly extending limiting section, a limiting groove is formed between it and the first sealing section, and a clamping effect is formed on the insertion of the annular rib through the inner wall of the limiting groove, so that the top of the annular rib is limited, which is beneficial to maintaining the connection stability between the annular rib and the seal, thereby ensuring the sealing stability of the seal between the adapter and the steam pressure plate, achieving good sealing effect and connection effect, and ensuring stable use of the exhaust channel.

[0043] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0044] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below. It should be noted that the embodiments of the present application and the features in each embodiment may be combined with each other without conflict.

[0045] like Figures 1 to 7 As shown, the present application provides a splash-proof electric thermos, comprising a container with an inner cavity 6 and a pot cover 1 snapped on the top of the container, the pot cover 1 is provided with a mounting port 11, and a breathable component connecting the outside with the inner cavity 6 is detachably provided at the mounting port 11, the breathable component comprises an adapter 2 and a steam pressure plate 3, the adapter 2 and the steam pressure plate 3 are connected to form an exhaust channel 5, and a sealing member 4 is clamped and fixed between the adapter 2 and the steam pressure plate 3, the exhaust channel 5 comprises a first channel 51, a plurality of first water retaining ribs 511 are provided in the first channel 51, and at least some adjacent two first water retaining ribs 511 are axially staggered.

[0046] In addition, a mounting cover 12 is provided at the top of the mounting opening 11, and the mounting cover 12 is provided with an air hole 121 communicating with the mounting opening 11, and a boss 122 is provided around the air opening, which is conducive to centrally guiding the gas discharged from the air opening, increasing the gas pressure at the air opening, improving the exhaust efficiency, and preventing the liquid from splashing around. A pot cover sealing ring 13 is provided at the bottom of the steam pressure plate 3, and the bottom of the steam pressure plate 3 is sealed after the air permeable component is assembled, so as to achieve a sealing effect between the pot cover 1 and other components of the electric thermos.

[0047] This solution forms an exhaust channel 5 by setting an adapter 2 to dock with the steam pressure plate 3. The exhaust channel 5 can be formed while the kettle lid 1 is assembled. The steps are simple and easy to operate. By setting a plurality of first water retaining ribs 511, boiling water sprayed from the inner cavity 6 is blocked in the exhaust channel 5. The boiling water falls back after being blocked by the water retaining ribs, thereby preventing the boiling water from surging up along the exhaust channel 5 to the installation port 11 and then splashing to the outside. At least two adjacent first water retaining ribs 511 are axially staggered to achieve the blocking of boiling water over the entire radial length in the first channel 51. The staggered first water retaining ribs 511 allow the steam to pass through the first channel 51 in a circuitous manner, avoiding the rapid outflow of steam and causing steam burns. By setting the first water retaining ribs 511, the cleaning burden and the risk of burns caused by boiling water overflow can be avoided while achieving steam discharge.

[0048] Since the breathable component is detachably arranged at the installation opening 11, it is convenient to disassemble and clean the breathable component from the installation opening 11, thereby avoiding liquid accumulation in the exhaust channel 5 formed by the breathable component and affecting the exhaust effect, and at the same time avoiding scale accumulation inside the breathable component, resulting in poor exhaust, bacterial growth and even affecting the quality of drinking water. This is beneficial to ensuring the cleanliness of the inside of the breathable component, achieving exhaust and anti-boiling effects, improving user experience and improving the safety of the electric thermos.

[0049] Preferably, the adapter 2 and the steam pressure plate 3 are detachably connected. When the adapter 2 is disassembled and separated from the steam pressure plate 3, they can be cleaned separately, thereby ensuring that the inside of the exhaust channel 5 formed by the connection between the adapter 2 and the steam pressure plate 3 is clean, avoiding liquid accumulation, maintaining a good exhaust effect of the exhaust channel 5, and avoiding the problem of scale accumulation in the exhaust channel 5 causing bacterial growth.

[0050] Preferably, the first channel 51 is arranged vertically and directly connected to the installation port 11, and multiple first water retaining ribs 511 are horizontally placed in the first channel 51, and the first water retaining ribs 511 are formed by the lateral extension of the inner wall of the adapter 2, which reduces the installation steps and is conducive to ensuring the structural stability of the first water retaining ribs 511, thereby stably achieving the blocking effect of boiling water.

[0051] like Figure 3 As shown, in one embodiment, the exhaust channel 5 also includes a second channel 52 extending vertically and a third channel 53 extending laterally, and the steam flows from the inner cavity 6 to the outside through the second channel 52, the third channel 53 and the first channel 51 in sequence, and the first channel 51 and the second channel 52 are laterally staggered.

[0052] By setting the second channel 52 and the third channel 53, the flow path of steam and boiling water is extended, and the second channel 52 is further set to extend vertically, and the third channel 53 is further set to extend horizontally, and the steam flow path passes through the vertical second channel 52, the horizontal third channel 53 and the first channel 51 in sequence. The flow path is tortuous, which can reduce the boiling water overflowing from the inner cavity 6 to the first channel 51, and the exhaust channel 5 has a long path, which is beneficial to reduce the potential energy of boiling water upwelling to the installation port 11 and reduce the overflow of boiling water; the first channel 51 and the second channel 52 are set to be horizontally offset to prevent the exhaust channel 5 from directly connecting the inner cavity 6 with the installation port 11, thereby preventing boiling water from directly overflowing from the inner cavity 6 to the installation port 11, and the tortuous exhaust channel 5 is used to block the boiling water to prevent boiling water from splashing from the installation port 11 to the outside.

[0053] like Figure 3 , Figure 5 As shown, in one embodiment, the adapter 2 is provided with a second water retaining rib 21 extending toward the third channel 53 .

[0054] By setting a second water retaining rib 21 toward the third channel 53, boiling water in the third channel 53 is blocked. Since the third channel 53 is arranged horizontally and the first channel 51 and the second channel 52 are horizontally offset, the second water retaining rib 21 blocks the boiling water splashed from the second channel 52 to the third channel 53, so that part of the boiling water cannot continue to surge along the third channel 53, further preventing the boiling water from overflowing.

[0055] Preferably, if Figure 3 As shown, the projection of the second water retaining rib 21 on the horizontal plane falls on the outside of the second channel 52 .

[0056] By setting the lateral position of the second water retaining rib 21, the second water retaining rib 21 will not directly face the channel opening of the second channel 52, thereby blocking the boiling water splashed out from the channel opening of the second channel 52 when flowing along the third channel 53, so that the boiling water falls back into the second channel 52, thereby improving the effect of the second water retaining rib 21 and effectively reducing the boiling water splashing from the third channel 53 to the first channel 51.

[0057] Preferably, the second water retaining rib 21 is formed by extending the adapter 2 downward from the bottom of the first channel 51, which is conducive to radially blocking the boiling water in the third channel 53 through the second water retaining rib 21, blocking a part of the boiling water from flowing to the first channel, and allowing the boiling water to fall directly back from the third channel 53 into the second channel 52.

[0058] like Figure 3 As shown, in one embodiment, a return surface 531 is provided on the bottom surface of the third channel 53 close to the first channel 51 , and the return surface 531 extends downwardly and obliquely from one side of the first channel 51 to one side of the second channel 52 .

[0059] Since the third channel 53 is located between the first channel 51 and the second channel 52, on the one hand, boiling water splashes from the second channel 52 to the third channel 53, and on the other hand, the boiling water blocked by the first water retaining rib 511 falls back to the third channel 53. Since the liquid in the inner cavity 6 of the electric thermos always maintains a boiling temperature when the water vapor is discharged and boiling water is generated, the continuously generated boiling water and the blocked boiling water that falls back are concentrated in the third channel 53. By setting the reflux surface 531, the speed at which the boiling water in the third channel 53 flows back to the second channel 52 is accelerated, and the boiling water falling back effect of the exhaust channel 5 is improved, thereby avoiding liquid accumulation in the exhaust channel 5, resulting in poor exhaust effect, and even scaling and bacteria breeding problems, which is conducive to keeping the inside of the exhaust channel 5 clean and achieving a good exhaust and anti-boiling effect.

[0060] Furthermore, the angle θ between the return surface 531 and the horizontal plane satisfies: 5°≤θ≤45°.

[0061] By limiting the angle between the return surface 531 and the horizontal plane, the boiling water return effect of the return surface 531 is improved. If the angle between the return surface 531 and the horizontal plane is too small, the boiling water flowing along the return surface 531 will flow slowly, and may gather on the return surface 531, which is not conducive to the rapid return of boiling water. If the angle between the return surface 531 and the horizontal plane is too large, the internal space of the third channel 53 will be small, which is not conducive to extending the boiling water flow path, and is not conducive to the third channel 53 and the first channel 51 and the second channel 52 to achieve the anti-splashing effect of boiling water. At the same time, by strengthening the guiding effect of the return surface 531 to avoid the situation of liquid retention and accumulation, it is conducive to ensuring the exhaust effect of the exhaust channel 5, and preventing the problem of liquid accumulation causing scale and breeding bacteria.

[0062] Specifically, the bottom portion of the third channel 53 forming the return surface 531 is located below the first channel 51, and the length of the return surface 531 is greater than the width of the first channel 51, which is beneficial for the boiling water that is blocked by the first water retaining rib 511 and falls back into the third channel to flow quickly into the second channel 52 through the return surface 531, thereby having a rapid diversion effect on the falling boiling water.

[0063] like Figure 3 , Figure 7 As shown, in one embodiment, the sealing member 4 close to the first channel 51 is provided with a transversely extending third water retaining rib 41 , and the projection of the third water retaining rib 41 on the horizontal plane is located in the first channel 51 .

[0064] The third water retaining rib 41 is provided on the sealing member 4 to enhance the blocking effect on boiling water. The third water retaining rib 41 is laterally arranged at a position close to the first channel 51. When boiling water enters the first channel 51, the third water retaining rib 41 is used to first block the boiling water, so as to reduce the amount of boiling water entering the first channel 51 and further enhance the anti-splashing effect. At the same time, since the third water retaining rib 41 is formed by extending part of the sealing member 4, it is beneficial to enhance the sealing effect between the adapter 2 and the steam pressure plate 3.

[0065] Further, the third water retaining rib 41 is axially offset from the adjacent first water retaining rib 511 , and the projection of the third water retaining rib 41 on the horizontal plane partially overlaps with the projection of the adjacent first water retaining rib 511 on the horizontal plane.

[0066] By arranging the third water retaining rib 41 to be axially offset from the adjacent first water retaining rib 511, the boiling water first passes through the third water retaining rib 41 for partial blocking, and the unblocked boiling water is blocked by the first water retaining rib 511 which is at a different radial position from the third water retaining rib 41 after passing through the height of the third water retaining rib 41, so that the boiling water can be blocked at multiple positions just when it enters the first channel 51, and the projection of the third water retaining rib 41 on the horizontal plane partially overlaps with the projection of the adjacent first water retaining rib 511 on the horizontal plane, thereby further improving the comprehensive blocking effect on the boiling water, causing the boiling water to fall back, which is beneficial to improving the anti-splashing effect.

[0067] It should be noted that, since the third water retaining rib 41 is formed by the transverse extension of the sealing member 4 , the third water retaining rib 41 can be located inside the first channel 51 or below the first channel 51 , and can also play a role in blocking boiling water.

[0068] like Figure 4 , Figure 5 As shown, in one embodiment, the adapter 2 includes a top plate 22 and a limiting rib 23 extending downward from the top plate 22, the steam compression plate 3 is provided with an annular rib 31 adapted to the limiting rib 23, and the seal 4 includes a first sealing section 42 clamped between the limiting rib 23 and the side wall of the annular rib 31 and a second sealing section 43 clamped between the top plate 22 and the top wall of the annular rib 31.

[0069] By providing the first sealing section 42 and the second sealing section 43, a multi-directional sealing effect is achieved between the adapter 2 and the steam pressure plate 3, thereby preventing steam or boiling water from entering the connection between the adapter 2 and the steam pressure plate 3, ensuring the structural stability of the adapter 2 and the steam pressure plate 3, thereby ensuring the structural functional stability of the exhaust channel 5, and always achieving the discharge of steam and the splash-proof effect of boiling water.

[0070] Preferably, if Figure 3As shown, a limiting section 431 extending downward is provided at the extended end of the second sealing section 43 , a limiting groove 44 is formed between the limiting section 431 and the first sealing section 42 , and the top end of the annular rib 31 is inserted into the limiting groove 44 .

[0071] By setting a downwardly extending limiting section 431, a limiting groove 44 is formed between it and the first sealing section 42, and a clamping effect is formed on the insertion of the annular rib 31 through the inner wall of the limiting groove 44, and the top of the annular rib 31 is limited, which is beneficial to maintaining the connection stability between the annular rib 31 and the sealing member 4, thereby ensuring the sealing stability of the sealing member 4 between the adapter 2 and the steam pressure plate 3, achieving good sealing effect and connection effect, and ensuring the stable use of the exhaust passage 5.
