Description

Technical Field

[0001] This invention relates to the field of humidifier technology, and more particularly to a tilting pressure relief structure for a liquid heating device and a humidifier using the same. Background Technology

[0002] Currently, when a humidifier is working, the steam in the water tank is discharged into the outside environment through the air outlet, which effectively increases air humidity and improves air quality, giving people fresher air.

[0003] However, when people accidentally knock over a humidifier, the humidifier is usually equipped with a leak-proof structure. This structure not only seals the water flow and steam in the tank, preventing them from flowing through the gaps between various plastic parts or components and then spilling onto the ground, but also causes some inconvenience for users.

[0004] The tilted humidifier continues to heat up, causing it to continuously produce steam. At this time, the internal pressure of the humidifier continues to increase. When the pressure is sufficient, the inner liner and top cover of the humidifier will burst open under the pressure, and the high-temperature water and steam will scatter and explode, posing a great danger. Summary of the Invention

[0005] The purpose of this invention is to provide a tilting pressure relief structure for a liquid heating device. The leak-proof component can ensure that the humidifier can prevent water from flowing out of the humidifier when tilted, and can also play a role in pressure relief, thereby improving the safety performance of the humidifier. It solves the problem that the container cannot release gas when tilted, and the continuous heating causes the internal pressure of the container to increase, which in turn leads to the container bursting.

[0006] The present invention also proposes a humidifier that, when tilted, not only prevents hot water from flowing out of the humidifier, but also reduces the risk of explosion caused by the continuous increase of internal pressure. This solves the problem that the container cannot release air when tilted, and the continuous heating leads to an increase in internal pressure, which in turn causes the container to burst.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A tilting and pressure-relief structure for a liquid heating device includes a humidifier body, a top cover, and a leak-proof structure. The top cover is installed on top of the humidifier body, and the leak-proof structure is located between the top cover and the humidifier body. The humidifier body includes, from bottom to top, a water tank, a first partition, and a steam guide hood. The steam guide hood is provided with a second air outlet and a third air outlet.

[0009] The first partition is located at the top of the water tank. The first partition is used to seal the outer edge of the water tank and separate the water tank from the leak-proof structure. The input end of the leak-proof structure is connected to the water tank, and the output end of the leak-proof structure is connected to the second air outlet and the third air outlet respectively. The leak-proof structure is used to prevent water from flowing out from the second air outlet or the third air outlet.

[0010] When the humidifier body is placed vertically, the steam is discharged outward from the second air outlet and the third air outlet; when the humidifier body is placed horizontally, the steam is discharged outward from the second air outlet or the third air outlet.

[0011] Optionally, the leak-proof structure includes a first leak-proof component and a second leak-proof component. The first leak-proof component is located on the right side of the humidifier body, and the second leak-proof component is located on the left side of the humidifier body. The first leak-proof component and the second leak-proof component are arranged opposite to each other.

[0012] The steam guide hood has a second air outlet at its left end and a third air outlet at its right end, with the second and third air outlets arranged opposite to each other.

[0013] The input end of the first leak-proof component is connected to the water tank, the output end of the first leak-proof component is connected to the second air outlet, the input end of the second leak-proof component is connected to the water tank, and the output end of the second leak-proof component is connected to the third air outlet.

[0014] Optionally, the first leak-proof component includes a second sealing cover and a first steam pipe. The second sealing cover is located at the right end of the humidifier body, and the bottom of the second sealing cover is connected to the water tank. The input end of the first steam pipe is fixedly connected to the second sealing cover, and the output end of the first steam pipe bypasses the front end of the humidifier and is connected to the second air outlet.

[0015] The second leak-proof component includes a third sealing cover and a second steam pipe. The third sealing cover is located at the right end of the humidifier body. The bottom of the third sealing cover is connected to the water tank. The input end of the second steam pipe is fixedly connected to the third sealing cover. The output end of the second steam pipe bypasses the front end of the humidifier and is connected to the third air outlet.

[0016] A humidifier uses a tilting pressure relief structure for a liquid heating device. A first partition is recessed at its center towards a water tank, forming a recessed portion. A second partition is located at the top of the recessed portion, forming a first receiving cavity with the second partition. Multiple through holes are provided at the bottom of the recessed portion for allowing steam to enter the first receiving cavity. The second partition and the bottom of a steam guide hood form a second receiving cavity. The humidifier body also includes a control component. The top of the control component is located at the top of the second partition, and the bottom of the control component passes through the second partition and is located within the first receiving cavity. The control component is used to seal or connect the channel between the first and second receiving cavities to control the flow path of the steam.

[0017] The steam guide hood has a first air outlet at its center, which is connected to the second receiving cavity, and the steam is discharged from the first air outlet.

[0018] The top of the second partition is provided with an elastic element, which is used to adjust the pressure of the first receiving cavity.

[0019] Optionally, the control assembly includes a steel ball, a spring, a seal, a pressure rod, and a first sealing cover. The second partition has a sliding hole. The top of the seal is located inside the first sealing cover. The pressure rod is fitted onto the top of the seal. The bottom of the seal extends through the sliding hole and has a sealing part for sealing the sliding hole.

[0020] A spring is fitted on the outside of the seal, the top of the spring abuts against the pressure rod, and the bottom of the spring abuts against the sealing part;

[0021] The steel ball moves within the cavity between the inner wall of the first sealing cover and the pressure rod. When the steel ball moves to the center of the pressure rod, the sealing part separates from the sliding hole. When the steel ball moves to the outer edge of the pressure rod, the sealing part seals the sliding hole.

[0022] Optionally, the longitudinal section of the humidifier body is elliptical.

[0023] Optionally, the second partition has a receiving hole and an exhaust hole, the receiving hole and the exhaust hole vertically penetrating the second partition;

[0024] The elastic element includes a vertical portion and a horizontal portion. The vertical portion is located inside the receiving hole, and the horizontal portion is horizontally mounted on the top of the vertical portion, and the horizontal portion horizontally covers the top of the vent hole.

[0025] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0026] 1. Both the first leak-proof component and the second leak-proof component are installed at the left and right ends of the humidifier body, forming a communicating vessel structure. When the humidifier body is tilted, the water tank continues to heat the cold water to produce water vapor. At this time, the air pressure inside the water tank continuously increases. The first and second leak-proof components can discharge the air pressure formed by the large amount of steam inside the water tank to the outside of the humidifier, thereby reducing the possibility of the humidifier exploding due to the continuous increase in air pressure inside the water tank.

[0027] 2. When the humidifier body is placed vertically, the control component connects the channel between the first receiving chamber and the second receiving chamber, so that steam is directly discharged from the through hole of the first partition into the first receiving chamber, and then discharged into the second receiving chamber under the action of the control component. At this time, the second receiving chamber is connected to the first air outlet, so that the steam can flow vertically upward and be discharged outward. Attached Figure Description

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

[0038] The following is combined with Figures 1 to 5 This invention describes a tilting pressure relief structure for a liquid heating device and a humidifier using the same, according to an embodiment of the present invention.

[0039] A tilting and pressure relief structure for a liquid heating device includes a humidifier body 1, a top cover 2, and a leak-proof structure 3. The top cover 2 is installed on the top of the humidifier body 1, and the leak-proof structure 3 is located between the top cover 2 and the humidifier body 1. The humidifier body 1 includes, from bottom to top, a water tank 11, a first partition 12, and a steam guide hood 14. The steam guide hood 14 is provided with a second air outlet 142 and a third air outlet 143.

[0040] The first partition 12 is located at the top of the water tank 11. The first partition 12 is used to seal the outer edge of the water tank 11 and separate the water tank 11 from the leak-proof structure 3. The input end of the leak-proof structure 3 is connected to the water tank 11, and the output end of the leak-proof structure 3 is connected to the second air outlet 142 and the third air outlet 143 respectively. The leak-proof structure 3 can prevent water from flowing out from the second air outlet 142 or the third air outlet 143. When the humidifier body 1 is placed vertically, the steam is discharged outward from the second air outlet 142 and the third air outlet 143; when the humidifier body 1 is placed horizontally, the steam is discharged outward from the second air outlet 142 or the third air outlet 143.

[0041] In one embodiment of this design, a tilting pressure relief structure for a liquid heating device includes a first partition 12 that seals the outer edge of the water tank 11, reducing water flow from the outer edge of the water tank 11 out of the humidifier body 1. When the humidifier is placed vertically, the water tank 11 continuously produces a large amount of steam. The steam passes through the first partition 12 and is discharged from the second air outlet 142 and the third air outlet 143 of the steam guide shroud 14 onto the top cover 2.

[0042] When the humidifier is tilted and placed horizontally, the steam can only pass through the second air outlet 142 or the third air outlet 143 under the action of the leak-proof structure 3, and then be discharged onto the top cover 2. This allows the humidifier body 1 to normally discharge steam and improve ambient air quality. The leak-proof structure 3 can prevent water from flowing out of the second air outlet 142 or the third air outlet 143, thus achieving the effect of preventing water leakage even when the humidifier body 1 is tilted. It can also play a role in pressure relief, solving the problem of the container not being able to discharge air when tilted, and the continuous heating causing the internal pressure of the container to increase, which could lead to the container bursting.

[0043] Furthermore, the leak-proof structure 3 includes a first leak-proof component 31 and a second leak-proof component 32. The first leak-proof component 31 is located on the right side of the humidifier body 1, and the second leak-proof component 32 is located on the left side of the humidifier body 1. The first leak-proof component 31 and the second leak-proof component 32 are arranged opposite to each other.

[0044] The steam guide hood 14 has a second air outlet 142 at its left end and a third air outlet 143 at its right end. The second air outlet 142 and the third air outlet 143 are arranged opposite to each other. The input end of the first leak-proof component 31 is connected to the water tank 11, the output end of the first leak-proof component 31 is connected to the second air outlet 142, the input end of the second leak-proof component 32 is connected to the water tank 11, and the output end of the second leak-proof component 32 is connected to the third air outlet 143.

[0045] The first leak-proof component 31 and the second leak-proof component are both installed at the left and right ends of the humidifier body 1. At this time, the first leak-proof component 31 and the second leak-proof component 32 can form a communicating vessel structure. When the humidifier body 1 is tilted, the water tank 11 continues to heat the cold water to produce water vapor. At this time, the air pressure inside the water tank increases continuously. The first leak-proof component 31 and the second leak-proof component 32 can discharge the air pressure formed by the large amount of steam inside the water tank 11 to the outside of the humidifier, thereby reducing the possibility of the air pressure inside the water tank continuously increasing and causing the humidifier to explode.

[0046] When the humidifier body 1 is placed horizontally and its right side is in contact with the horizontal plane, steam flows in the second leak-proof assembly 32 and then exits from the third air outlet 143. Hot water flows in the first leak-proof assembly 31. Since the first leak-proof assembly 31 is connected to the second air outlet 142 on the left side of the humidifier, the water level of the hot water is unlikely to exceed the second air outlet 142, making it difficult for the hot water to flow out, thus achieving the effect of preventing water leakage when tilted.

[0047] Furthermore, the first leak-proof component 31 includes a second sealing cover 311 and a first steam pipe 312. The second sealing cover 311 is located at the right end of the humidifier body 1. The bottom of the second sealing cover 311 is connected to the water tank 11. The input end of the first steam pipe 312 is fixedly connected to the second sealing cover 311. The output end of the first steam pipe 312 bypasses the front end of the humidifier and is connected to the second air outlet 142.

[0048] The second leak-proof component 32 includes a third sealing cover 321 and a second steam pipe 322. The third sealing cover 321 is located at the right end of the humidifier body 1. The bottom of the third sealing cover 321 is connected to the water tank 11. The input end of the second steam pipe 322 is fixedly connected to the third sealing cover 321. The output end of the second steam pipe 322 bypasses the front end of the humidifier and is connected to the third air outlet 143.

[0049] When the humidifier body 1 is placed horizontally and its right side is in contact with the horizontal plane, hot water flows from the water tank 11 into the second sealing cover 311, and then flows in the first steam pipe 312. Since the water level in the water tank 11 is unlikely to be higher than the second steam outlet 142, the hot water in the first steam pipe 312 is unlikely to reach the second steam outlet 142 and flow out from it, achieving the effect of preventing water leakage when tilted.

[0050] At this time, steam is discharged from water tank 11 into the third sealing cover 321, and then flows in the second steam pipe 322. Since the third air outlet 143 is located at the right end of the humidifier body 1, the steam can be smoothly discharged from the third air outlet 143, so that the humidifier body 1 can also discharge steam when tilted, thereby increasing the humidity in the environment.

[0051] A humidifier uses a tilting pressure relief structure for a liquid heating device. The center of the first partition 12 is recessed towards the water tank 11 to form a recess 121. A second partition 122 is provided on the top of the recess 121. The second partition 122 and the recess 121 form a first receiving cavity 123. The bottom of the recess 121 is provided with a plurality of through holes for steam to pass into the first receiving cavity 123. The bottom of the second partition 122 and the steam guide shroud 14 form a second receiving cavity 124.

[0052] The humidifier body 1 is also provided with a control component 13. The top of the control component 13 is located at the top of the second partition 122, and the bottom of the control component 13 passes through the second partition 122 and is located in the first receiving cavity 123. The control component 13 is used to seal or connect the channel between the first receiving cavity 123 and the second receiving cavity 124 to control the flow path of steam.

[0053] The steam guide hood 14 has a first vent 141 at its center, which is connected to the second receiving cavity 124, and the steam is discharged from the first vent 141. The top of the second partition 122 is provided with an elastic element 15, which is used to adjust the pressure of the first receiving cavity 123.

[0054] When the humidifier body 1 is placed vertically, the control component 13 connects the channel between the first receiving cavity 123 and the second receiving cavity 124, so that steam is directly discharged from the through hole of the first partition 12 into the first receiving cavity 123, and then discharged into the second receiving cavity 124 under the action of the control component 13. At this time, the second receiving cavity 124 is connected to the first air outlet 141, so that the steam can flow vertically upward and be discharged outward.

[0055] In addition, the elastic element 15 can adjust the pressure of the first receiving cavity 123 to prevent excessive internal pressure of the humidifier body 1 from causing an explosion.

[0056] Furthermore, the control component 13 includes a steel ball 131, a spring 132, a seal 133, a pressure rod 134, and a first sealing cover 135. The second partition 122 has a sliding hole 1220. The top of the seal 133 is located inside the first sealing cover 135. The pressure rod 134 is sleeved on the top of the seal 133. The bottom of the seal 133 passes through the sliding hole 1220 and has a sealing part 1331, which is used to seal the sliding hole 1220.

[0057] A spring 132 is sleeved on the outside of the sealing element 133. The top of the spring 132 abuts against the pressure rod 134, and the bottom of the spring 132 abuts against the sealing part 1331.

[0058] The steel ball 131 moves within the cavity between the inner wall of the first sealing cover 135 and the pressure rod 134. The steel ball 131 moves to the center of the pressure rod 134, and the sealing part 1331 separates from the sliding hole 1220. The steel ball 131 moves to the outer edge of the pressure rod 134, and the sealing part 1331 seals the sliding hole 1220.

[0059] When the humidifier body 1 is placed vertically, the steel ball 131 is located at the top of the pressure rod 134 and presses down on the pressure rod 134, thereby driving the sealing part 1331 away from the sliding hole 1220, so that the steam flows from the water tank 11 into the first receiving cavity 123, and then passes through the sliding hole 1220, the second receiving cavity 124 and the first air outlet 141 in sequence, thus smoothly being discharged from the humidifier body 1.

[0060] When the humidifier body 1 is placed horizontally, the steel ball 131 moves inside the first sealing cover 135 and then sits on the side wall of the first sealing cover 135, releasing the pressure on the pressure rod 134. At this time, the sealing part 1331 moves downward under the action of the spring 132, so that the sealing part 1331 abuts against the sliding hole 1220. At this time, the sealing part 1331 can seal the sliding hole 1220, so that steam cannot flow from the sliding hole 1220 into the second receiving cavity 124.

[0061] It is worth noting that the seal 133 in this solution is a steam valve.

[0062] Furthermore, the longitudinal section of the humidifier body 1 is approximately elliptical. Specifically, in this design, the longitudinal section of the humidifier body 1 is set to approximately elliptical, referring to... Figure 1 The curvature of the left and right sides of the humidifier body 1 is small, while the curvature of the front and rear ends is large, so that when the humidifier body 1 is tilted, the left and right sides can make stable contact with the ground, reducing the occurrence of the humidifier body 1 continuously rolling.

[0063] Furthermore, the second partition 122 has a receiving hole 1221 and an exhaust hole 1222, which vertically penetrate the second partition 122; the elastic member 15 includes a vertical part 151 and a horizontal part 152, the vertical part 151 is located in the receiving hole 1221, the horizontal part 152 is horizontally installed on the top of the vertical part 151, and the horizontal part 152 horizontally covers the top of the exhaust hole 1222.

[0064] It is worth noting that the vertical portion 151 of the elastic element 15 is vertically located within the receiving hole 1221, and the bottom surface of the horizontal portion 152 abuts against the top surface of the second partition 122. When there is a large amount of steam and high pressure in the first receiving cavity, the steam can flow into the exhaust hole 1222, then push the horizontal portion 152 upwards, and then flow into the second receiving cavity 124, thereby balancing the pressure within the first receiving cavity 123 and reducing the possibility of an explosion in the humidifier body 1.

[0065] In addition, the steam and water flow in the second receiving cavity 124 are difficult to connect with the elastic element 15 to flow into the first receiving cavity 123, thus solving the problem of steam backflow and contamination of the water tank 11.

[0066] Other components and operations of a humidifier with a non-leaking function according to an embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
