Technical Field

The application relates to the field of household articles, in particular to an iron telescopic rod.

Background

After the garment steamer is electrified by adding water, the inner core adopts a heater to enable the warm water to be vaporized into high-temperature and high-pressure steam, and the hot steam is released through the steam conduit and the spray head. The garment is sprayed at the folds of the garment during use, and garment steamer accessories such as trousers line clamps, brushes, dust removing brushes, ironing lining plates and the like are matched, and the garment and cloth are flattened through the actions of pulling, pressing and spraying, so that the garment achieves the effects of flattening, softening, removing mites, sterilizing and removing dust.

The clothes are often pressed by a flat iron, so that the fabric of the clothes is easy to damage, and the fabric fiber is hard and aged. The garment steamer is used for ironing in a natural hanging state, avoids direct damage to fabrics under the dual actions of self gravity and high-temperature steam (the temperature is above 100 ℃), and can iron the garment quickly, conveniently and easily, so that the garment is bright like a new garment, and the optimal wearing shape is maintained. When ironing clothes, the contact part with clothes (the air outlet part of the spray head) of the garment steamer is far away from the steam source, and dirt generated by the domestic water at high temperature can not be easily sprayed on the clothes like a flat iron or a steam ironing brush, but is completely reserved in a far-away bottom heater dirt storage chamber (positioned at the bottommost end of a garment steamer heating furnace). Meanwhile, the high-temperature steam also has the effects of dust removal, sterilization and disinfection. When the garment steamer is used, the steam outlet speed is usually 30 seconds, and people do not need to worry about putting bad clothes to scald. The flat iron needs to be completely boiled when in use, the speed is low, the flat iron needs to be vertically placed at the use interval, and the like, and the flat iron is complicated.

The garment steamer adopts the steam iron 0, the specific structure of the steam iron 0 is as shown in fig. 6 and 7, the steam iron 0 comprises a shell 01, a handle 02 is arranged on the shell 01, a driving button 021 is arranged on the handle 02, a steam pipe 03 for providing ironing steam and electric power is arranged on one side of the shell 01, a mounting groove 04 for being mounted on the garment steamer is further arranged on one side of the shell 01, and a steam hole 06 and a clamping groove 05 for clamping the garment steamer are formed in the working face of the iron.

The conventional ironing mode generally adopts a hand-held iron 0, and the steam spray head is continuously moved towards the ironing board by the iron 0, so that each part of clothes laid on the ironing board can be fully ironed, but the hand-held steam iron 0 is continuously moved, and the time and the labor are wasted, and the ironing is uneven.
