TECHNICAL FIELD

[0001] The present application relates to the technical field of steam irons, in particular to a vaporization structure for a steam iron. BACKGROUND

[0002] In order to restore the clothes wrinkled after washing to flatness, a steam iron is usually used for ironing, which softens the fibers of the clothes by using high-temperature steam, and then eliminates the creases and wrinkles of the clothes by ironing with the high-temperature ironing plate of the steam iron. When the steam iron is working, a vaporization structure is needed to heat the water to generate steam for the steam iron to iron clothes.

[0003] A common vaporization structure for a steam iron is designed in the related art, which includes a pot body, a heating cavity and a steam cavity are arranged in the pot body, a heating element is arranged in the pot body for heating the heating cavity, a water inlet opening communicating with the inside of the heating cavity is formed at the top of the pot body. A steam inlet channel communicating with the water inlet opening is formed on one side of the steam cavity, and a steam outlet channel communicating with the outside of the pot body is formed on the other side of the steam cavity. A movable plug body is movably arranged in the steam cavity, a spring is arranged in the steam cavity for driving the movable plug body to block the steam inlet channel, and a pull rod extending out of the pot body is fixedly connected to the movable plug body.

[0004] When steam is generated by using this technology, water is first injected into the heating cavity through the water inlet opening, and then the water inlet opening is closed. Then the heating element heats the heating cavity to make the water vaporize. Finally, the pull rod is pressed down, the pull rod pushes the movable plug body away from the steam inlet channel, the steam in the heating cavity enters the steam cavity through the water inlet opening and the steam inlet channel, and then escapes from the pot body through the steam outlet channel to supply the steam iron for ironing clothes.

[0005] In the process of implementing the present application, it is found that at least the following problems exist in the technology: In the water injection process, water flows in the water inlet opening and splashes into the steam inlet channel, which causes the steam to be mixed with water that has not completely vaporized when the steam is output, affecting the quality of the steam. CONTENT OF THE UTILITY MODEL

[0006] In order to avoid water splashing into the steam inlet channel as much as possible, prevent the output steam from being mixed with water that has not completely vaporized as much as possible, and improve the quality of the steam, the present application provides a vaporization structure for a steam iron.

[0007] The vaporization structure for a steam iron provided by the present application adopts the following technical solution:

[0008] The utility model provides a steam generation structure for steam iron, including the kettle body, be provided with heating cavity and steam cavity in the kettle body, the kettle body top is provided with the water injection opening that communicates heating cavity inside, steam cavity is provided with the steam inlet channel and steam outlet channel, steam outlet channel communicates outside the kettle body, the movable plug body of steam cavity is movable, steam cavity is provided with the spring of driving movable plug body and blocks the steam inlet channel, and the movable plug body is fixedly connected with the lever that projects outside the kettle body, steam inlet channel communicates with heating cavity top, and the water baffle is fixedly arranged in heating cavity top, and the water baffle is located steam inlet channel's directly below, and the water baffle and steam inlet channel leave the gap for steam to pass between them.

[0009] By adopting the above technical scheme, when water is injected, water is injected into the heating cavity from the water injection opening at the top of the kettle body, and in this process, the water injection opening and the steam inlet channel are not directly connected, and the water cannot contact and enter the steam inlet channel during falling. When the water falls to the bottom of the heating cavity, the water will splash due to impact, and the splashed water will be blocked by the water baffle located directly below the steam inlet channel and flow back to the heating cavity. During heating, the water is vaporized to form steam, and in this process, the water will also boil and splash, but it will still be blocked by the water baffle into the steam inlet channel. The vaporized steam enters the steam inlet channel through the gap between the water baffle and the steam inlet channel, then reaches the steam cavity, and finally, the steam is discharged from the steam outlet channel on the other side of the steam cavity to supply the steam iron for ironing clothes. In this way, water is prevented from splashing into the steam inlet channel as much as possible, and the output steam is prevented from being mixed with incompletely vaporized water as much as possible, thereby improving the steam quality.

[0010] As a preferred embodiment, the steam inlet channel includes a horizontal hole and a vertical hole. The horizontal hole is opened in the horizontal direction and communicates with the steam cavity. The vertical hole is opened in the vertical direction, the bottom of the vertical hole communicates with the heating cavity, and the top of the vertical hole communicates with the horizontal hole.

[0011] By adopting the above technical scheme, during the temperature rise in the heating cavity, steam will separate from the heating cavity and enter the steam inlet channel. The steam will re-condense on the inner wall of the steam inlet channel. At this time, the vertical hole plays a role of water hanging, allowing the liquefied water to flow back to the heating cavity along the inner wall of the vertical hole, further reducing the liquid water entering the steam cavity, and ensuring the quality of the steam discharged from the steam outlet channel.

[0012] As a preferred embodiment, the end of the water baffle is fixedly provided with a fixed plate, the fixed plate and the water baffle are bent from the same metal sheet, and the fixed plate is detachably connected to the top of the heating cavity by bolts.

[0013] By adopting the above technical scheme, the installation and disassembly of the water baffle become convenient. When the water baffle needs to be cleaned of scale or maintained, the water baffle can be easily disassembled by bolts, thereby improving the maintainability of the device.

[0014] Preferably, the baffle plate is curved at both ends towards the direction away from the steam inlet channel.

[0015] By using the above technical solution, when the liquefied water falls on the baffle plate from the longitudinal hole, the liquid water slides along the curved surface into the heating cavity, which avoids the accumulation of the falling water on the baffle plate as much as possible, and improves the efficiency of water returning to the heating cavity.

[0016] Preferably, the movable plug body comprises a sealing ring and a plug block, the plug block is fixedly connected with the push rod, the sealing ring is installed on the plug block, and the sealing ring abuts against the side wall on the side of the steam cavity facing the steam inlet channel.

[0017] By using the above technical solution, the sealing ring enhances the sealing effect of the movable plug body on the steam inlet channel, ensures the sealing performance of the heating cavity, improves the instant heating efficiency of the heating cavity, reduces the possibility of steam leakage when it is not needed to be output, and thus improves the utilization efficiency of steam and the working performance of the steam iron.

[0018] Preferably, the plug block comprises a pressing part, and the pressing part abuts against the side of the sealing ring away from the steam inlet channel.

[0019] By using the above technical solution, when the movable plug body abuts against the steam inlet channel, the pressing part abuts against the side of the sealing ring away from the steam inlet channel, which further enhances the fixing and pressing effect of the sealing ring, ensures the position stability of the sealing ring during use, and maintains good sealing performance.

[0020] Preferably, the plug block comprises a centering guide part, the centering guide part extends into the steam inlet channel, the centering guide part is tapered, the small-diameter end of the centering guide part is fixedly connected with the push rod, the diameter of the large-diameter end of the centering guide part is adapted to the inner wall of the steam inlet channel, the diameter of the large-diameter end of the centering guide part is smaller than the outer diameter of the sealing ring, and the diameter of the large-diameter end of the centering guide part is larger than the inner diameter of the sealing ring.

[0021] By using the above technical solution, when the movable plug body moves close to the steam inlet channel, the steam inlet channel corrects the position of the movable plug body through the centering guide part, which ensures that the sealing ring is aligned with the steam inlet channel when the movable plug body abuts against the steam inlet channel, thereby reducing the poor sealing or steam leakage caused by position deviation, and further ensuring the stability and reliability of steam output. At the same time, the tapered centering guide part reduces the contact area between the steam and the sealing ring, and can also disperse the pressure of the steam, thereby prolonging the service life of the sealing ring.

[0022] Preferably, a water injection pipe is fixedly arranged in the water injection port, and the bottom end of the water injection pipe extends to the bottom of the heating cavity.

[0023] By adopting the technical scheme, the water injection pipe makes the water injection process more concentrated and stable, water can directly reach the bottom of the heating cavity, the splashing of water during water injection is reduced, and the possibility of water splashing into the steam inlet channel is further reduced.

[0024] To sum up, the present application has at least one of the following beneficial technical effects:

[0025] 1. By setting the steam inlet channel communicating with the heating cavity, and the water baffle located directly below the steam inlet channel, the splashing water during water injection is blocked from entering the steam inlet channel, the content of unvaporized water in the steam is reduced, and the steam quality is improved.

[0026] 2. By setting the horizontal hole, the vertical hole and the curved water baffle, the vertical hole plays a water hanging role, and the liquefied water of the steam can be returned to the heating cavity, ensuring the quality of the steam discharged from the steam outlet channel.

[0027] 3. By setting the plug, the sealing ring, the centering guide part and the pressing part, the sealing effect of the movable plug body is enhanced, steam leakage is reduced, and steam utilization efficiency and steam iron working performance are improved. BRIEF DESCRIPTION OF DRAWINGS
