Description

Technical Field

[0001] The utility model relates to the technical field of steam brushes, in particular to a handheld steam brush. Background Art

[0002] The existing Chinese patent with announcement number CN214831349U discloses a handheld steam brush with an upper and lower separated special-shaped water tank, including a steam brush body and a water tank. The water tank is detachably connected with the steam brush body in the upper and lower directions through a locking mechanism. The water tank is a special-shaped water tank, the special-shaped water tank has a first special-shaped mating surface, the steam brush body has a second special-shaped mating surface, and the first special-shaped mating surface and the second special-shaped mating surface have a unique engagement direction; when the first special-shaped mating surface and the second special-shaped mating surface are engaged with each other, the locking mechanism fastens the special-shaped water tank and the steam brush body together.

[0003] However, the above-mentioned steam brush has the following disadvantages: the steam brush is the same as the existing steam brushes on the market, which pumps water in the water tank into the steam brush body, and then heats the steam brush body to form steam for ejection. This steam brush can use steam to iron the surface of clothes to eliminate wrinkles on the surface of clothes, but this steam brush that uses high-temperature steam to iron clothes cannot iron clothes made of some specific fabrics for a long time, resulting in unsatisfactory sterilization and inactivation effects inside the clothes. In addition, the traditional steam brush that uses water vapor to iron clothes has a low internal steam pressure, resulting in insufficient steam ejection pressure from the air outlet, making it difficult to penetrate some thicker clothes.
