Description

Technical Field

[0001] This invention relates to the field of electric iron technology, and more particularly to an airflow weight-reducing electric iron. Background Technology

[0002] Electric irons are common garment ironing tools, widely used in homes and garment processing. As user experience demands increase, the convenience and comfort of prolonged handheld operation have become key pain points. Currently, electric irons on the market mainly consist of a shell, a control unit, and a heating ironing unit. The ironing unit is mostly made of metal, and combined with the internal components, the overall weight is considerable. Even with lightweight improvements, prolonged handheld use can still cause a feeling of heaviness, leading to arm fatigue and negatively impacting the user experience.

[0003] Current technologies primarily reduce weight by using lightweight composite materials, but due to structural and functional limitations, the weight reduction effect is limited and may increase costs. Furthermore, they cannot fundamentally solve the problem of excessive friction between the ironing surface and the ironed item caused by its own weight, which can easily damage high-end fabrics. Improvements to existing electric irons mainly focus on steam and temperature control, without offering effective solutions to the pain points caused by gravity. Steam can only soften fibers and cannot achieve significant weight and drag reduction.

[0004] Therefore, there is an urgent need for a structure that can counteract the weight of the electric iron and reduce friction, thereby overcoming the shortcomings of existing technologies and meeting the demand for convenient and comfortable ironing.

[0005] This invention is based on the above circumstances. Summary of the Invention

[0006] This invention overcomes the shortcomings of the prior art and provides an airflow-based weight-reducing electric iron with a structure that can counteract the weight of the electric iron and reduce friction, thus meeting the needs for convenient and comfortable ironing.

[0007] This invention is achieved through the following technical solution:

[0008] An airflow-based weight-reducing electric iron includes an outer shell, a control unit, a high-speed air supply device, and a heating ironing unit. The ironing unit is located at the lower end of the outer shell and has an ironing surface for contacting the object being ironed. The outer shell has an air inlet structure connected to the air inlet end of the high-speed air supply device, and the lower end face of the outer shell has an air outlet structure connected to the air outlet end of the high-speed air supply device. This allows the high-speed airflow generated by the high-speed air supply device to flow through the air outlet structure and be ejected towards the object being ironed. The high-speed airflow can generate an upward thrust on the electric iron, thereby offsetting part of the weight of the electric iron or making the electric iron levitate. The ironing surface protrudes downward from the air outlet structure.

[0009] As described above, in an airflow-weight-reducing electric iron, the air outlet structures are symmetrically arranged on both sides of the ironing unit, or the number of air outlet structures is greater than or equal to three and evenly distributed on the outside of the ironing unit.

[0010] As described above, an airflow-weight-reducing electric iron has an ironing unit with a steam generating chamber and a heating unit for heating the steam generating chamber. The outer shell has a water tank, and a water pump for drawing liquid from the water tank into the steam generating chamber is provided between the water tank and the ironing unit. The bottom of the ironing unit has several steam outlets that communicate with the steam generating chamber.

[0011] As described above, an airflow-weight-reducing electric iron has an inner shell inside the outer shell, a detachable connection structure between the water tank and the inner shell for detachable connection of the water tank to the inner shell, an avoidance hole for avoiding the water tank on the outer shell, a water inlet hole for adding water to the water tank, and a plug for sealing the water inlet hole.

[0012] As described above, in an airflow-weight-reducing electric iron, a connecting component is provided between the water tank and the water pump's suction end to enable communication between the two. The connecting component includes a first insertion part on the water tank and a second insertion part on the inner shell connected to the water pump's suction end via a water pipe. The first insertion part has a valve chamber communicating with the inner cavity of the water tank, and the first insertion part has an insertion hole communicating with the valve chamber. The second insertion part has an insertion post that can be inserted into the valve chamber, and the insertion post has a connecting hole that enables communication between the valve chamber and the water pump's suction end. The valve chamber has an elastic plug that can be opened when the insertion post is inserted and seals the insertion hole when the insertion post is pulled out.

[0013] As described above, in an airflow-weight-reducing electric iron, a sealing ring is provided at one end of the valve cavity near the insertion hole, and the sealing ring has a through hole for the insertion post to pass through. The elastic plug includes a spring and a plug bead that can be pushed by the spring. A water inlet notch communicating with the connecting hole is provided on the side wall of the insertion post end.

[0014] As described above, in an airflow-weight-reducing electric iron, the air outlet structure includes several air outlets located next to the ironing unit, and an air guide channel between the air outlets and the air outlet end of the high-speed air supply device.

[0015] As described above, the airflow weight reduction type electric iron has an air inlet structure including an air inlet located on the top of the outer shell and an air inlet grille for restricting the entry of foreign objects, and a filter mechanism is provided between the air inlet and the air inlet grille.

[0016] As described above, in an airflow-weight-reducing electric iron, the high-speed air supply device includes a BLDC high-speed motor with fan blades at the output end. The rotational speed of the BLDC high-speed motor is greater than 50,000 RPM, and the wind speed of the high-speed airflow blown out from the air outlet structure is greater than 5 m / s.

[0017] As described above, in an airflow-weight-reducing electric iron, the ironing unit, high-speed air supply device, and water pump are electrically connected to the control unit. The outer casing is equipped with a power switch, a fan speed adjustment button, a temperature adjustment button, and a water pump switch.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This invention generates a high-speed airflow through a high-speed air delivery device and sprays it toward the object being ironed. The airflow counterforce can counteract part of the weight of the electric iron or make it levitate, greatly reducing the feeling of weight when holding it, avoiding arm fatigue caused by prolonged ironing, and improving user comfort and ironing efficiency.

[0020] The reverse push force reduces the pressure between the ironing surface and the object being ironed, thereby reducing friction. This not only reduces the push force required during operation but also prevents the fabric from being scratched or pilled, making it especially suitable for high-end and easily damaged fabrics such as silk and wool.

[0021] The ironing surface protrudes downwards from the air outlet structure, ensuring that the airflow does not affect the effective contact between the ironing surface and the object being ironed. This balances weight reduction and drag reduction with ironing flatness, without sacrificing the core ironing function. The structural design is simple, easy to implement, and cost-controllable.

[0033] The present invention will now be further described with reference to the accompanying drawings:

[0034] like Figures 1 to 10 The illustrated airflow-based weight-reducing electric iron includes an outer shell 1, a control unit 2, a high-speed air supply device 3, and a heating ironing unit 4. The ironing unit 4 is located at the lower end of the outer shell 1 and has an ironing surface 41 for contacting the object being ironed. The outer shell 1 is provided with an air inlet structure 5 that communicates with the air inlet end of the high-speed air supply device 3, and an air outlet structure 6 that communicates with the air outlet end of the high-speed air supply device 3 is provided on the lower end surface of the outer shell 1, so that the high-speed airflow generated by the high-speed air supply device 3 flows through the air outlet structure 6 and is sprayed towards the object being ironed. The high-speed airflow can generate an upward thrust on the electric iron, thereby offsetting part of the weight of the electric iron or making the electric iron float. The ironing surface 41 protrudes downward from the air outlet structure 6.

[0035] This invention generates a high-speed airflow through a high-speed air supply device 3 and sprays it towards the object being ironed. The reverse thrust of the airflow can counteract part of the iron's weight or levitate it, significantly reducing the burden during hand operation, avoiding arm fatigue caused by prolonged ironing, and improving user comfort and ironing efficiency. The reverse thrust reduces the pressure between the ironing surface and the object being ironed, thereby reducing friction. This reduces the pushing force required during operation and prevents the fabric from being scratched or pilled, making it especially suitable for high-end and fragile fabrics such as silk and wool. The ironing surface 41 protrudes downward from the air outlet structure 6, ensuring that the airflow does not affect the effective contact between the ironing surface 41 and the object being ironed. This balances weight reduction and drag reduction with ironing smoothness without sacrificing the core ironing function. The structural design is simple, easy to implement, and cost-effective.

[0036] In some embodiments, the control unit 2 is a PCBA, and the high-speed air supply device 3 is a BLDC high-speed motor with fan blades at the output end. The BLDC high-speed motor can be a BLDC motor with a speed exceeding 50,000 RPM, or other types of high-speed motors. A mounting bracket 31 for fixing the high-speed air supply device 3 is provided inside the housing 1. The mounting bracket 31 can be connected to the housing 1 by threaded fasteners or other connection methods. A power cord sleeve 10 is provided on the housing 1 for the power cord to pass through. The wind speed of the high-speed airflow blown out from the air outlet structure 6 is greater than 5 m / s. If the wind speed is too low, the reaction force is too small, resulting in less offsetting of the weight of the electric iron.

[0037] In some embodiments, the air outlet structure 6 is symmetrically arranged on both sides of the ironing unit 4, or the number of the air outlet structure 6 is greater than or equal to three and evenly distributed on the outside of the ironing unit 4, which can guide the high-speed airflow evenly and stably to the ironed object, ensure that the airflow thrust is evenly distributed, and avoid insufficient local thrust affecting the weight reduction effect.

[0038] Furthermore, the air outlet structure 6 includes a plurality of air outlet holes 61 disposed beside the ironing unit 4, and an air guide channel 62 between the air outlet holes 61 and the air outlet end of the high-speed air supply device 3.

[0039] In some embodiments, the ironing unit 4 includes a steam generating chamber and a heating unit capable of heating the steam generating chamber. A water tank 73 is provided on the outer casing 1. A water pump 74 is provided between the water tank 73 and the ironing unit 4 to draw liquid from the water tank 73 into the steam generating chamber. The bottom of the ironing unit 4 has several steam outlets 72 communicating with the steam generating chamber. Steam can be ejected through the steam outlets 72, helping to soften clothing fibers and further improving ironing smoothness and efficiency. The inclusion of a steam generating chamber and a heating unit within the ironing unit 4 is a conventional technique in the art and does not need to be shown in the figures; therefore, it will not be described in detail here.

[0040] Furthermore, the outer shell 1 is provided with an inner shell 75, and a detachable connection structure 76 is provided between the water tank 73 and the inner shell 75 to allow the water tank 73 to be detachably connected to the inner shell 75. The outer shell 1 is provided with a clearance hole 11 for avoiding the water tank 73, and the water tank 73 is provided with a water inlet hole 731 for adding water to it. The water inlet hole 731 is provided with a plug 732 for sealing it.

[0041] Specifically, the inner housing 75 is fixedly connected to the outer housing 1 by threaded fasteners or other connection methods such as snap-fits. The inner housing 75 is provided with a connecting bracket 755, which is connected to the inner housing 75 by threaded fasteners or adhesive or other connection methods. The detachable connection structure 76 consists of a snap-fit ​​structure for locking the water tank and an unlocking key 761 for unlocking the snap-fit ​​structure, both located on the connecting bracket 755. This detachable connection structure 76 is a conventional locking structure available on the market and will not be described in detail here.

[0042] Furthermore, the water pump 74 is housed within the inner housing 75, and the upper part of the ironing unit 4 is provided with a wiring channel 42 for the water pipe and the drain end of the water pump 74 to enter the ironing unit 4. The water pump 74 can be connected to the inner housing 75 or the connecting bracket 755 via threaded fasteners. The ironing unit 4 can be connected to the inner housing 75 via threaded fasteners or other connection methods. The movement of the ironing unit 4 can also be restricted between the inner housing 75 and the ironing unit 4 via a limiting insert structure.

[0043] In some embodiments, a communication component is provided between the water tank 73 and the water pump 74's suction end, enabling communication between the two. The communication component includes a first insertion portion 81 on the water tank 73 and a second insertion portion 82 on the inner shell 75 connected to the water pump 74's suction end via a water pipe. The first insertion portion 81 has a valve chamber 811 communicating with the inner cavity of the water tank 73, and a insertion hole 812 communicating with the valve chamber 811. The second insertion portion 82 has a insertion post 821 that can be inserted into the valve chamber 811, and a communication hole 822 communicating between the valve chamber 811 and the water pump 74's suction end. The valve chamber 811 has an elastic plug that opens when the insertion post 821 is inserted and seals the insertion hole 812 when the insertion post 821 is pulled out. This prevents water leakage when the water tank 73 is pulled out.

[0044] Specifically, a sealing ring 813 is provided at one end of the valve cavity 811 near the insertion hole 812. The sealing ring 813 is provided with a through hole 814 for the insertion post 821 to pass through. The elastic plug includes a spring 815 and a plug bead 816 that can be pushed by the spring 815. A water inlet notch 823 communicating with the connecting hole 822 is provided on the side wall of the end of the insertion post 821.

[0045] In some embodiments, the lower part of the outer casing 1 is provided with a bottom cover 100, the bottom cover 100 having an extension opening 101 for the ironing unit 4 to extend out, and the bottom cover 100 being connected to the outer casing 1 or the inner casing 75 by means of threaded fasteners or snap-fit ​​connections. The air outlet 61 is provided on the bottom cover 100.

[0046] In some embodiments, the air intake structure 5 includes an air inlet 51 located on the top of the outer casing 1 and an air intake grille 52 for restricting the entry of foreign objects. A filter mechanism 53 is provided between the air inlet 51 and the air intake grille 52. A support frame 531 is provided at the air inlet 51. The filter mechanism 53 includes a filter screen 532 sleeved on the support frame 531 and a filter sponge 533 sleeved on the outside of the filter screen 532. The air intake grille 52 can be threaded to the outer casing 1, or it can be connected to the outer casing 1 by other connection methods such as threaded fasteners.

[0047] In some embodiments, the ironing unit 4, the high-speed air supply device 3, and the water pump 74 are electrically connected to the control unit 2 to achieve coordinated control of each component and ensure stable and orderly operation of the equipment. The outer casing 1 is equipped with a power switch 91, a wind speed adjustment button 92, a temperature adjustment button 93, and a water pump switch 94, which control the start and stop of the equipment, the airflow intensity, the ironing temperature, and the steam supply. The button layout is intuitive and easy to operate. Users can flexibly adjust the buttons according to the fabric of the clothing and ironing needs to adapt to different scenarios, further improving the convenience of operation and user experience.
