As shown in FIGS. 1 and 5, a pumpless steam ironing device comprises a main body 100, a handle 200, a water tank 300, an atomizing device 400 and an ironing panel 500.

The handle 200 extends in an up-down direction. The main body 100 is located at an upper end of the handle 200 and extends in a front-back direction. When manufactured, the main body and the handle may be integrally connected, or manufactured separately and then assembled together.

The ironing panel 500 is located at a front end of the main body 100 and provided with steam outlets. A mounting position is formed on a back side of the ironing panel 500 and an upper side of the main body 100.

The atomizing device 400 is located at a front position inside the main body 100.

The water tank 300 is located above the main body 100, and the water tank 300 and the handle 200 are located on upper and lower sides of the main body 100 respectively. The water tank 30 is mounted at the mounting position, a front end of the water tank 300 is close to the ironing panel 500, and a back end of the water tank 300 is flush with a back end of the main body 100, such that the water tank 300 is approximately as long as the main body 100. When water is stored in the water tank, the weight of water can be uniformly distributed in the length direction (front-back direction) of the main body, such that the situation that the burden of the hands of users is increased due to a large deviation of the center of gravity of the ironing device when the handle is held by hand is avoided. A bottom 302 of the water tank 300 is inclined to guide water to flow from the water tank to a water passage. As shown in FIGS. 1 and 5, the water tank 300 is provided with an air hole 303, and the air hole 303 is located at an upper end of a back portion of the water tank 300. When the ironing panel is in a vertical state or in a horizontal state, the air hole is located at a high position of the water tank. A water outlet 301 is located in a bottom side of a front portion of the water tank 300, such that the air hole 303 and the water outlet 301 are located in two extreme positions of the water tank respectively. The water outlet is used for discharging water, and the air hole is used for ventilation. The air hole can assist the water outlet in discharging water and can also prevent water from leaking via the water outlet. The diameter of the water outlet is less than the diameter of the water passage.

A stationary member 101 is configured in the main body 100, and the stationary member 101 is arranged on the back side of the ironing panel 500 and located above the atomizing device 400. The water passage 102 extending in the up-down direction is arranged in the stationary member 101 and located in a front portion of the main body 100. A lower end of the water passage 102 is fixedly connected to a water inlet of the atomizing device 400. An upper end of the water passage 102 is detachably connected to the water outlet 301 of the water tank. In this way, the water tank is connected to the atomizing device by means of the water passage, and water can be delivered from the water tank into the atomizing device. When water needs to be added to the water tank, the water tank can be detached from the main body.

Based on the abovementioned assembly relation, when the ironing panel 500 is in a vertical state (hanging ironing position) shown in FIG. 1 or in a horizontal state (horizontal ironing position) shown in FIG. 5, the water passage 102 is lower than the water tank 300 to allow water to automatically flow from the water tank 300 into the atomizing device 400 via the water passage 102.

The water passage 102 is provided with a valve 103. The valve 103 comprises a control portion 108, which extends out of the main body and is used for turning on or off the valve. When the valve is turned on by means of the control portion, the water passage will be opened, and water is delivered from the water tank to the atomizing device. When the valve is turned off by means of the control portion, the water passage will be closed, and water will not be delivered from the water tank into the atomizing device.

The valve 103 comprises a valve port 104, a valve plug 106 and a valve rod 107. The valve port 104 is located in a path in the water passage 102. The valve plug 106 is arranged on the valve rod 107 and located at the valve port 104. The valve rod 107 is movably configured on the main body and used for driving the valve plug to block or open the valve port. The valve rod 107 is arranged in the front-back direction and extends backwards out of the main body 100, and the control portion 108 is arranged at a back end of the valve rod 107. The valve port 104 is a connection cavity intersecting with the water passage 102, and the valve port 104 is provided with a throttle cavity 105 deviating from the water passage 102. The valve plug 106 is located at a front end of the valve rod 107.

As described above, no matter whether the ironing panel 500 is in the vertical state (hanging ironing position) shown in FIG. 1 or in the horizontal state (horizontal ironing position) shown in FIG. 5, the water passage 102 is lower than the water tank 300 to allow water to automatically flow from the water tank into the atomizing device via the water passage. In actual use, the ironing panel may be configured at any angle between the vertical state and the horizontal state. In addition, the valve rod 107 may be moved forwards or backwards by means of the control portion 108 to open or close the water passage. As shown in FIG. 2, the valve port 104 is completely blocked by the valve plug 106, the water passage 102 is closed, and water is not delivered from the water tank into the atomizing device. When the valve rod 107 is moved backwards from the state shown in FIG. 2, the valve plug 106 will move backwards synchronously until the valve port 104 is half opened, as shown in FIG. 3, and at this moment, the water passage 102 is opened and throttled, so water is delivered at a low rate. When the valve rod 107 is further moved backwards from the state shown in FIG. 3, the valve plug 106 will move backwards synchronously until the valve port 104 is completely opened, as shown in FIG. 4, and at this moment, the water passage 102 is completely opened and not throttled, so water is delivered at a high rate.

As described above, the ironing device delivers water by means of the water passage that can be opened or closed rather than a water pump, such that control of the water pump and pipelines required for delivering water by the water pump are avoided, the manufacturing cost is reduced, and fault points of the pumpless steam ironing device are reduced. In addition, the pumpless steam ironing device can be used for hanging ironing, horizontal ironing, or ironing in other positions, thus being easy to use.

During ironing, water flows from the water tank into the atomizing device via the water passage, the atomizing device heats the water to atomize the water into steam, and the steam is released via the steam outlets in the ironing panel to be used for ironing.
