Description

TECHNICAL FIELD

[0001] The utility model relates to liquid heating container technical field, specifically is a kind of liquid heating device's pour water-tight structure. BACKGROUND

[0002] Currently, in the working time of humidifier, electric rice cooker, health pot and other liquid heating containers, the internal liquid needs to be heated constantly, with the increase of liquid temperature, water vaporizes into steam continuously, leading to the continuous rise of pressure in the container body. To ensure that these liquid heating containers can run safely, stably and efficiently, the steam generated in the main body needs to be discharged from the gas outlet to the external environment in time, so as to maintain the balance of the internal pressure of the container.

[0003] However, when people use liquid heating containers and accidentally knock them down, the liquid heating containers are generally provided with a water leakage prevention structure. The water leakage prevention structure not only seals the water flow and water vapor in the water tank, but also allows the water flow and water vapor in the water tank to be discharged to the outside. The liquid heating container continues to heat and pour after power off, which will produce steam continuously. However, the water leakage prevention structure always blocks the steam discharge port, which causes the internal pressure of the liquid heating container to increase continuously. When the pressure is large enough, the liquid heating container will burst under the action of pressure, and the high-temperature water and steam will scatter and burst, which is dangerous.

[0037] The utility model discloses a kind of liquid heating devices, and the structure is described below. Figs. 1 to 4

[0038] A kind of liquid heating device's pour water-tight structure, including cover body 1 and main body, the cover body 1 is rotationally installed on the top of the main body;The bottom of the cover body 1 is provided with leakage prevention base plate 2 and top cover 3 from bottom to top, steam guide cover 4 and multiple leakage prevention devices 5 are arranged between the leakage prevention base plate 2 and the top cover 3, the leakage prevention base plate 2 is provided with multiple first steam hole groups 21, multiple first steam hole groups 21 are respectively communicated with the main body, the top cover 3 is provided with gas outlet 31;

[0039] Multiple leakage prevention devices 5 and multiple first steam hole groups 21 one-to-one correspondence, the air inlet end of the leakage prevention device 5 and corresponding first steam hole group 21 are communicated with each other, the air outlet end of the leakage prevention device 5 and the inner wall of the steam guide cover 4 are communicated with each other, the bottom of the steam guide cover 4 is sealed with the leakage prevention base plate 2, the top of the steam guide cover 4 is sealed with the top cover 3, the steam guide cover 4, the leakage prevention base plate 2 and the top cover 3 form the discharge channel of steam between them;

[0040] ​A plurality of leakage-proof devices 5 are arranged outside the steam guide cover 4, and each leakage-proof device 5 comprises a gravity one-way valve assembly 51 for opening or closing the air outlet end of the leakage-proof device 5.

[0041] When the cover 1 is placed horizontally, all the gravity one-way valve assemblies 51 are in an open state, and steam is collected from the air outlet ends of the leakage-proof devices 5 into the steam guide cover 4 and discharged from the air outlet 31 of the top cover 3.

[0042] When the cover 1 is tilted, the gravity one-way valve assembly 51 at the highest point is in an open state, and the remaining gravity one-way valve assemblies 51 are in a closed state. Steam is collected from the air outlet end of the open leakage-proof device 5 into the steam guide cover 4 and discharged from the air outlet 31 of the top cover 3.

[0043] It should be noted that the present scheme can be applied to humidifiers, rice cookers, health pots and other devices for heating liquids. When the main body is tilted, based on the principle of gravity, the gravity one-way valve assembly 51 at the highest point is in an open state, and the remaining gravity one-way valve assemblies 51 are in a closed state. This design effectively prevents liquid from overflowing from the air outlet end of the leakage-proof device 5 at the low point, solves the problem of water leakage during traditional main body tilting, greatly improves the safety during use, and avoids problems such as scalding, damage to equipment or pollution of the environment caused by water leakage.

[0044] When the main body is in a vertical placement state, all the gravity one-way valve assemblies 51 are in an open state, and steam can be quickly and smoothly discharged. In the tilted state, the gravity one-way valve assembly 51 at the highest point remains open, and steam can continue to be collected from the air outlet end of the open leakage-proof device 5 into the steam guide cover4, and smoothly discharged from the air outlet 31 of the top cover 3, ensuring that the air pressure inside the main body is always balanced, avoiding excessive pressure inside the main body due to steam accumulation, and reducing the risk of explosion and other safety hazards.

[0045] A plurality of leakage-proof devices 5 are arranged outside the steam guide cover 4, and when the main body is tilted in a certain direction, the gravity one-way valve assembly 51 in the leakage-proof device 5 at the bottom position will quickly respond and close under the action of gravity, preventing liquid from flowing out of the air outlet end. Compared with the traditional design, the leakage-proof device 5 arranged around greatly expands the leakage-proof range, completely eliminates the risk of water leakage caused by uncertain tilting direction, and provides stable and reliable leakage-proof protection for the user.

[0046] The leakage-proof device 5 further comprises a first steam cover 52, which is sealingly connected with the leakage-proof base plate 2, and a flow space for steam is formed between the first steam cover 52 and the leakage-proof base plate 2.

[0047] The gravity one-way valve assembly 51 comprises a gravity ball 53 and a valve body 54, the valve body 54 separates the first steam cover 52 into a first air inlet cavity and a first air outlet cavity, the first end of the valve body 54 is arranged towards the first air outlet cavity, the first air inlet cavity is in communication with the first steam hole group 21, and the first air outlet cavity is in communication with the air outlet end of the leakage-proof device 5;

[0048] The first air outlet cavity is arranged close to the side wall of the cover body 1, and the first air inlet cavity is arranged close to the center of the cover body 1, and the gravity ball 53 is located in the first air outlet cavity;

[0049] In the horizontal state, the gravity ball 53 and the valve body 54 are close to each other, and the valve body 54 is in an open state; in the pouring state, the gravity ball 53 at the bottom and the corresponding valve body 54 are separated from each other, and the valve body 54 is in a closed state.

[0050] Steam enters the first air inlet cavity from the first steam hole group 21, flows to the first air outlet cavity through the valve body 54, and finally flows into the steam guide cover 4. This orderly flow path not only speeds up the steam exhaust speed, but also effectively avoids the accumulation of steam in the leakage-proof device 5, ensures the stability of the air pressure in the main body, maintains the normal progress of the heating process, and prevents the heating from being abnormal or the main body from being damaged due to unstable air pressure.

[0051] The first air outlet cavity is arranged close to the side wall of the cover body 1 and the first air inlet cavity is arranged close to the center of the cover body 1, so that the gravity ball 53 can accurately respond and play a role in the pouring state. When pouring, the gravity ball 53 at the bottom approaches the side wall of the cover body 1 under the action of gravity, thereby separating from the valve body 54, closing the valve body 54, and effectively preventing liquid from overflowing from the first air outlet cavity at the bottom.

[0052] In addition, when the main body is in a vertical placement state, the gravity ball 53 quickly approaches the valve body 54, thereby opening the valve body 54, and ensuring that the steam can be discharged from the air outlet end of the leakage-proof device 5.

[0053] The first inclined surface 24 is arranged on the bottom of the first air outlet cavity, and the first inclined surface 24 is inclined from top to bottom to one side of the first air inlet cavity, and the first inclined surface 24 is used to guide the gravity ball 53 and the valve body 54 to approach each other.

[0054] The design of the first inclined surface 24 enables the gravity ball 53 to quickly and accurately approach the valve body 54 under the guidance of the first inclined surface 24 when the main body returns to the horizontal state, so that the valve body 54 quickly returns to the open state.

[0055] When the main body is in a vertical placement state, the first inclined surface 24 can abut against the side wall of the gravity ball 53, reducing the positional deviation of the gravity ball 53 and separating the gravity ball 53 from the valve body 54, thereby causing the valve body 54 to be closed, the steam cannot be smoothly discharged, and the case of excessive pressure in the main body occurs.

[0056] The valve body 54 comprises a reset member 55, a plug 56 and a valve core 57; the plug 56 horizontally penetrates the valve core 57, the end of the plug 56 movably abuts against the valve core 57, the end of the plug 56 is used for plugging the air outlet at the end of the valve core 57, the reset member 55 movably sheaths the plug 56, the front end of the reset member 55 is fixedly connected with the front end of the plug 56, and the rear end of the reset member 55 is fixedly connected with the front end of the valve core 57.

[0057] The gravity ball 53 abuts against the plug 56, the plug 56 moves towards the first air inlet chamber, and the valve core 57 is in an open state; the gravity ball 53 is separated from the plug 56, the reset member 55 drives the plug 56 to move towards the first air outlet chamber, the end of the plug 56 plugs the air outlet at the end of the valve core 57, and the valve core 57 is in a closed state.

[0058] The gravity ball 53 as a trigger device is extremely sensitive to the pouring state of the main body. When the main body is in a vertical placement state, the gravity ball 53 abuts against the plug 56 under the action of the first inclined surface 24, promotes the plug 56 to move towards the first air inlet chamber, and the valve core 57 is immediately opened, so that the steam can be smoothly discharged.

[0059] When the main body is in a pouring state, the gravity ball 53 at the bottom is separated from the plug 56 under the action of gravity, the reset member 55 drives the plug 56 to move towards the first air outlet chamber so that the end of the plug 56 plugs the valve core 57, thereby avoiding unnecessary overflow of steam and liquid, and realizing precise switching of the steam discharge and leakage prevention functions.

[0060] Meanwhile, the gravity ball 53 at the top abuts against the plug 56 at any time under the action of gravity, so that the valve body 54 is in an open state, ensuring that the steam can be discharged from the top leakage prevention device 5, and reducing the failure caused by excessive gas pressure in the main body.

[0061] The valve core 57 comprises a first air permeable pipe 571 and a second air permeable pipe 572, the end edge of the first air permeable pipe 571 is fixedly connected with the edge of the second air permeable pipe 572, a plurality of air permeable holes are formed in the first air permeable pipe 571, the air permeable holes horizontally penetrate the front end and the rear end of the first air permeable pipe 571, a locking hole is horizontally arranged in the center of the second air permeable pipe 572, the locking hole horizontally penetrates the front end and the rear end of the second air permeable pipe 572, and the locking hole and the air permeable hole are in communication with each other.

[0062] The plug 56 comprises a connecting portion 561 and a blocking portion 562, the end of the connecting portion 561 is fixedly connected with the blocking portion 562, the connecting portion 561 is respectively in sliding connection with the air hole and the locking hole, and the blocking portion 562 is in active abutment with the second air tube 572 and blocks the locking hole;

[0063] The reset member 55 is movably sleeved on the connecting portion 561, the leading end of the reset member 55 is fixedly connected with the leading end of the connecting portion 561, and the trailing end of the reset member 55 is fixedly connected with the first air tube 571.

[0064] When the gravity ball 23 is close to the plug 56, the gravity ball 53 drives the plug 56 to move towards the first air inlet cavity, so that the blocking portion 562 is separated from the locking hole. At this time, the steam located in the first air inlet cavity enters the first air outlet cavity from the locking hole and the plurality of air holes in sequence, and flows orderly to the subsequent steam discharge system.

[0065] When the main body is inclined, the gravity ball 23 located at the bottom is separated from the plug 56 under the action of gravity, at this time, the reset key 561 restores the deformation and pushes the plug 56 to move towards the first air outlet cavity, so that the blocking portion 562 blocks the locking hole, at this time, the valve core 57 is in a closed state, neither steam nor liquid can pass through the valve core 57 and enter the first air outlet cavity.

[0066] Among them, a plurality of air holes are arranged in the first air tube 571, which can increase the flow area and flow efficiency of the steam, so that the steam can flow more quickly and more smoothly.

[0067] The steam conveying device 6 is further arranged between the leakage-proof base plate 2 and the top cover 3, the leakage-proof base plate 2 is provided with a second steam hole group, the second steam hole group and a plurality of first steam hole groups 21 are arranged in a ring shape, the steam conveying device 6 is arranged opposite to the second steam hole group, an input end of the steam conveying device 6 is in communication with the second steam hole group through an input pipe 23, and an output end of the steam conveying device 6 is in communication with the inner wall of the steam guide cover 4.

[0068] The second steam hole group and a plurality of first steam hole groups 21 are arranged in a ring, which expands the steam collection range. The steam in the main body can be quickly collected from different positions and multiple directions, effectively avoiding the accumulation of steam in a local position. Compared with the traditional single-position steam collection method, the steam collection efficiency is significantly improved.

[0069] When the main body is tilted to one side of the second steam hole group, steam and hot water will flow into the input pipe 23 from the second steam hole. Since the steam delivery device 6 is arranged opposite to the second steam hole group, the pipe of the input pipe 23 is relatively long, so that hot water is difficult to flow into the inside of the steam delivery device 6 under the action of gravity, and steam will preferentially rise into the steam delivery device 6 due to its small density, realizing rapid discharge. At this time, hot water is effectively blocked and cannot follow steam into the steam delivery device 6 due to the double restrictions of the structure of the input pipe 23 and gravity, thereby avoiding hot water leakage.

[0070] The steam delivery device 6 comprises a second steam cover 61 and a third gas permeable pipe 62, the third gas permeable pipe 62 separates the second steam cover 61 into a second air outlet cavity and a second air inlet cavity, and the second air outlet cavity and the second air inlet cavity are in communication with each other through the third gas permeable pipe 62.

[0071] The second steam cover 61 is provided with a second inclined surface 63 on the bottom wall of the second air outlet cavity, and the second inclined surface 63 is inclined from top to bottom to the second air inlet cavity.

[0072] The second inclined surface 63 guides steam to flow quickly and efficiently in the second air outlet cavity, shortens the residence time of steam in the second steam cover 61, and avoids steam accumulation. After steam enters the second air outlet cavity from the second air inlet cavity through the third gas permeable pipe 62, the steam can quickly flow to the steam guide cover 4 under the influence of the second inclined surface 63.

[0073] During steam discharge, part of the steam will condense into liquid water in the second steam cover 61. The second inclined surface 63 guides the condensed water to the second air inlet cavity, preventing the condensed water from accumulating at the bottom of the second air outlet cavity.

[0074] The steam guide cover 4 has a structure of being low in the middle and high on the periphery.

[0075] After the steam condenses into liquid, the structure of being low in the middle and high on the periphery can make the condensed liquid flow to the middle of the steam guide cover 4. Therefore, when the main body is tilted, the condensed liquid is difficult to flow out from the top edge of the steam guide cover 4, reducing the risk of liquid leakage.

[0076] In addition, the design of being low in the middle and high on the periphery can disperse the pressure from above, making the steam guide cover 4 more stable when bearing steam pressure and external force, reducing the probability of failure caused by structural deformation or damage, and prolonging the service life of the equipment.

[0077] The technical principles of the present application are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the present application, and cannot be interpreted as limiting the protection scope of the present application in any way. Based on the explanations herein, other specific embodiments of the present application can be conceived by those skilled in the art without creative efforts, and these embodiments will all fall within the protection scope of the present application.
