[0013] In a preferred embodiment, the water tank is further provided with a second mounting column located above the water outlet, and a water outlet control assembly is provided in the second mounting column. The water outlet control assembly includes a water outlet valve rod, a spring, a lower gear rod, an upper gear rod and a rotating cap from bottom to top, and the rotating cap is sunk on the top surface of the hand grip.

[0014] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0015] 1. The steam iron of this utility model utilizes a neck connection between the grip and the steam chamber, fully utilizing the longitudinal space between the grip and the area below it, allowing the lower portion of the grip and the neck to form a water tank. This structure of the steam iron eliminates the traditional practice of placing the water tank within the iron body below the handle opening. This eliminates the waste of longitudinal space caused by the handle opening, which would otherwise restrict the water tank to the lower portion of the iron body. Therefore, the steam iron of this utility model eliminates the water tank structure within the iron body below the neck, which occupies the majority of its volume. This reduces its overall size and makes the overall structure more compact, making it both convenient to use and easy to carry, especially for travel.

[0016] 2. In the steam iron of the present invention, the neck not only serves as a part of the water tank, but also has an outer wall with an inwardly concave arc-shaped curved surface structure, and can be used to wind the power cord, making it easier to reel in the power cord. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] FIG1 is a schematic structural diagram of the present utility model.

[0018] FIG2 is a partial cross-sectional view of the present invention. DETAILED DESCRIPTION

[0019] The specific embodiments of the present invention will be described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0020] Referring to FIG1 , an improved steam iron comprises an iron body 1. A grip 10 is provided at the top of the iron body 1, forming a winding space for the power cord between the grip 10 and the iron body 1. A steam chamber 20 and a base plate 30 with an electric heater 40 are provided at the bottom of the iron body 1. The grip 10 is an ellipsoid or ellipsoid-like structure designed to fit the human hand. The thickness of the ellipsoid does not exceed 5 cm, making it easy to hold.

[0021] 1 and 2 , the bottom of the handle 10 and the top of the steam chamber 20 are connected by a neck 50 to form the winding space. The cross section of the neck 50 is elliptical and smaller than the cross section of the handle 10. The top of the neck 50 and the bottom of the handle 10 are connected by a circular arc transition, and the bottom of the neck 50 and the top of the steam chamber 20 are also connected by a circular arc transition. The outer wall of the neck 50 forms a concave arc surface structure, which can be used to wind the power cord, making it easier to reel in the power cord.

[0022] 1 and 2 , the lower portion of the grip portion 10 and the neck portion 50 form a water tank 60. Since the grip portion 10 is an ellipsoid and the cross-sectional area of ​​the neck portion 50 is smaller than that of the grip portion 10, the water tank is a trumpet-shaped structure that is larger at the top and smaller at the bottom, thereby increasing the capacity of the water tank.

[0023] Referring to Figures 1 and 2, the water tank 60 and steam chamber 20 are preferably integrally formed, but can also be connected using a snap-fit ​​mechanism. A water outlet 600 is provided at the bottom of the water tank, communicating with the steam chamber. A temperature regulator 21 is located within the steam chamber 20. The water tank is provided with a first mounting post 61, which houses a temperature adjustment rod 611. The bottom of the temperature adjustment rod 611 is connected to the temperature regulator 21, and the top is connected to an adjustment knob 612, which is recessed into the top surface of the grip 10.

[0024] 2 , the water tank 60 has a water inlet on the top, and a water inlet cover 11 is correspondingly provided on the top surface of the grip portion 10 for closing the water inlet. The water inlet cover 11 is detachably mounted on the water inlet.

[0025] 2 , the water tank 60 is further provided with a second mounting column 62 located above the water outlet 600. The second mounting column 62 is provided with a water outlet control assembly, which includes, from bottom to top, a water outlet valve stem 621, a spring 622, a lower gear rod 623, an upper gear rod 624, and a rotating cap 625. The specific installation structure of the water outlet control assembly is conventional technology in this field and will not be described in detail here. The lower part of the water outlet valve stem 621 passes through the bottom of the second mounting column 62, and the end rests on the water outlet 600, while the rotating cap 625 is sunk on the top surface of the hand grip 10. The water outlet control assembly is mainly used to control the amount of water flowing out of the water tank into the steam chamber.

[0026] The steam iron structure of the present invention changes the traditional arrangement of the water tank on the iron body below the handle through hole, fully utilizes the longitudinal space between the grip and the lower part of the grip, so that the lower part of the grip and the neck form the water tank. The longitudinal space is not wasted due to the arrangement of the handle through hole, which results in the water tank being restricted to the lower part of the iron body. The overall structure is relatively compact, making it small in size.

[0027] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
