DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0027] With reference to Figures 1 and 2, the utility model provides a steam iron, comprising an iron housing 1, in which various heating components of the iron are arranged. A heating plate 3 is provided under the housing 1, and the clothes are ironed by contacting the heating plate 3 through the heating plate 3. A circle of retractable ring pads 2 is provided on the periphery of the heating plate 3, and the ring pads 2 extend from the heating plate 3 to surround the heating plate 3, and the ring pads 2 and the surface of the heating plate 3 form a steam cavity. A plurality of steam ports 31 are provided on the lower surface of the heating plate 3, and steam is sprayed into the steam cavity through the steam ports 31 in cooperation with the various components of the iron housing 1. Through the formation of the steam cavity, the steam is concentrated and has higher penetration, the ironing efficiency is better, and water is saved.

[0028] Furthermore, a fixed frame 4 is provided beneath the housing 1, to which the heating plate 3 is secured. The ring pad 2 is retractably connected to the fixed frame 4, allowing it to retract into the fixed frame 4 when subjected to external forces, allowing the heating plate 3 to directly contact the clothing being ironed. By retracting the ring pad 2, it extends to form a steam chamber, saving water while improving steam efficiency. By compressing the ring pad 2 through external force, the heating plate 3 can directly contact the clothing, enabling the iron to achieve two ironing modes to meet different needs.

[0029] Please refer to Figures 1 to 5. The heating plate 3 is directly fixed to the fixed frame 4 by screws, and the ring gasket 2 is directly arranged outside the heating plate 3 and inside the fixed frame 4. An inner extension is provided above the ring gasket 2, which can be stuck on the heating plate 3 when extended downward to the maximum limit. In addition, a plurality of elastic members are provided between the ring gasket 2 and the fixed frame 4, which provide a downward elastic force on the ring gasket 2. The elastic member can be set as a spring or a spring sheet 5, etc. In this embodiment, the elastic member is set as a spring sheet 5, and the spring sheet 5 can support the ring gasket in a larger range to ensure the supporting effect. By setting a plurality of spring sheets 5 between the ring gasket 2 and the fixed frame 4, the ring gasket 2 is pushed downward. When the ring gasket 2 is subjected to an external force greater than the elastic force, it can retract upward so that its outermost layer is flush with the heating plate 3, so that the heating plate 3 directly contacts the clothes.

[0030] Furthermore, an inner extension is provided above the ring pad 2. The diameter of the through hole formed by the inner extension is smaller than the diameter of the heating plate 3. This ensures that the ring pad will not fall directly outside the heating plate 3 when it is lowered, but is directly connected to the top of the heating plate 3 through the inner extension. In addition, the through hole formed by the inner extension can allow the various pipes on the heating plate 3 to pass through, so that the operation of various components will not be affected during expansion and contraction.

[0031] The spring sheet 5 is located between the fixed frame 4 and the ring gasket 2, directly abutting the lower surface of the fixed frame 4 and the upper surface of the inner extension, thereby elastically connecting the ring gasket 2 to the fixed frame 4. The inner extension is clamped onto the heating plate 3 to limit the downward movement of the ring gasket 2. The fixed frame 4 is positioned above the ring gasket 2 to limit its upward movement. The abutment of the spring sheet 5 allows the ring gasket 2 to extend and retract between the fixed frame 4 and the heating plate 3, while being maintained in an extended state by the spring sheet 5.

[0032] Please continue to refer to Figures 1 to 5. The iron irons with water vapor. A water injection assembly 6 is also provided in the outer shell 1 for injecting water into the heating plate 3, and ironing is performed by generating steam through heat. The water injection assembly 6 is provided above the heating plate 3, and includes a water tank 61 and a water pump 62. The water tank 61 is connected to the water pump 62 through a water pipe 63, and the water pump 62 can pump the water in the water tank 61. Among them, a water inlet 33 is provided at the upper end of the heating plate 3, which is connected to the water pipe 63 of the water injection assembly 6. The water pump 62 connects the water inlet 33 to the water tank 61 through the water pipe 63, and pumps the water in the water tank 61 into the water inlet 33, thereby entering the heating plate 3.

[0033] Furthermore, a water inlet is provided on the top of the housing 1, and its position corresponds to that of the water tank 61, making it convenient for external users to fill water into the water tank 61 from the water inlet. In addition, a water inlet cap 11 is provided at the water inlet, which is opened when filling water and covered by the water inlet cap 11 at other times to prevent contamination of the interior of the water tank 61.

[0034] The heating plate 3 is equipped with a heating tube 7 and a steam chamber 32. The heating tube 7 is used to heat the heating plate 3, causing water to form steam within the steam chamber 32. The heating tube 7 runs through the heating plate 3, avoiding the steam chamber 32, and heats the heating plate 3. The steam chamber 32 is connected to a water inlet 33, allowing water to flow into the steam chamber 32, where it is heated by the heating plate 3 to form steam. The generated steam is ejected from the steam port 31 below to iron the bottom of the clothes.

[0035] Furthermore, the iron is provided with a controller 64 for controlling the on / off switching of the water pump 62. When the heating tube 7 heats the heating plate 3 to a certain temperature, the controller 64 turns on the water pump 62, injecting water into the heating plate 3, thereby generating steam for ironing. A power button 12 is provided above the housing 1. The power button 12 is located at a position corresponding to the controller 64 and is connected to the controller 64. Pressing the power button 12 switches the controller 64 on and off.

[0036] At the same time, a power line interface is provided at the rear end of the housing 1, which can be connected to a power line to connect the iron to a power source. After the power line interface is connected to the power source, power can be supplied to the heating tube 7 and the controller 64, so that the water and electricity start to work, thereby causing the iron to start spraying steam for ironing.

[0037] As another embodiment of this solution, a connecting frame 21 is provided between the ring pad 2 and the fixing frame 4, and the ring pad 2 is set on the iron through the connecting frame 21. The connecting frame 21 is detachably connected to the fixing frame 4, which makes it convenient for the user to remove the ring pad 2 so that it can be heated directly by the heating plate 3.

[0038] The retractable ring pad 2 extends to form a steam chamber, saving water while improving steam efficiency. The heating plate 3 can be directly in contact with clothing by removing the connecting frame 21. During use, the user can simply remove the connecting frame 21, thereby removing the ring pad 2, allowing the iron to be ironed directly on the heating plate 3 without applying excessive pressure.

[0039] In this embodiment, except for the placement of the ring pad 2, the remaining structure is consistent with the first embodiment. A water injection assembly 6 is also provided for injecting water into the heating plate 3, generating steam through heat for ironing. A heating tube 7 and a steam chamber 32 are provided within the heating plate 3. The heating tube 7 heats the heating plate 3, generating steam within the steam chamber 32. A controller 64 is also provided within the iron, controlling the on / off of the water pump 62.

[0040] To use the steam iron of the present invention, water is poured into the water tank 61, the power supply is connected to heat the heating plate 3, and the controller 64 is activated by pressing the power button 12, causing the water pump 62 to pump water into the heating plate 3, thereby generating steam. The steam in the heating plate 3 is ejected into the steam chamber. The user then directs the steam chamber toward the garment to be ironed. The ring pad 2 is used to maintain a certain distance between the heating plate 3 and the garment, thereby enhancing the steam's penetrating power and enabling it to penetrate thicker fabrics.

[0041] When the user requires direct contact between the heating plate 3 and the clothes, the user applies downward force to retract the ring pad 2, and directly brings the heating plate 3 into contact with the clothes, forming a traditional ironing mode.

[0042] The formation of a steam chamber concentrates the steam, improving its penetration and increasing ironing efficiency while conserving water. The retractable ring pad 2 extends to form a steam chamber, saving water while increasing steam efficiency. Externally compressing the ring pad 2 allows the heating plate 3 to directly contact clothing, enabling the iron to achieve two ironing modes to meet different needs. The ring pad 2 ensures that the soleplate is always lifted off the fabric without pressing down, preventing direct contact and burns caused by prolonged standby.

[0043] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
