Technical Field
[0001] This utility model relates to the field of ironing technology, and in particular to a negative pressure iron with high efficiency water absorption. Background Technology
[0002] Irons are common household appliances used to iron clothes, making them smooth and neat. Currently, most irons on the market use a water pump to supply water to an electrically heated steam generator, which then sprays steam outwards. This type of iron has the following drawbacks in practical use: 1. Water pump is prone to damage: As one of the core components of the iron, the water pump works in a high temperature and high humidity environment for a long time and is easily affected by limescale, which can easily cause malfunctions, making the iron unable to work properly, thus reducing the lifespan of the iron and increasing maintenance costs.
[0003] 2. Poor ironing results: When ironing clothes, especially when using a steam iron, the steam jets often carry the clothes away from the iron, preventing them from adhering properly. This lack of close contact between the iron and the garment leads to poor ironing results, requiring repeated ironing to achieve the desired effect and impacting ironing efficiency.
[0004] 3. Difficulty in water intake: Without a water pump, the water intake problem of the steam generator is difficult to solve. How to achieve stable and reliable water intake for the steam generator is a challenge faced by existing technologies.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, wherein: Figure 1 This is one of the exploded view diagrams of this utility model; Figure 2 This is a longitudinal sectional view of the present invention; Figure 3 yes Figure 2 Sectional view at point AA; Figure 4 This is the second exploded view of this utility model; Figure 5 yes Figure 2 A magnified view of a portion of point B in the middle. Detailed Implementation
[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] like Figures 1 to 5 As shown, this utility model includes a housing 1 and a water tank 2. A steam generator 3 and a fan 4 are provided inside the housing 1. In this embodiment, the steam generator 3 is preferably an electrically heated steam generator, and the fan 4 is preferably a high-speed fan.
[0021] The front end of the housing 1 is equipped with an ironing plate 5, which has several steam nozzles 51 and air inlets 52. The steam nozzles 51 are connected to the output end of the steam generator 3 for spraying steam. The air inlets 52 are connected to the air intake side of the fan 4 for drawing in air. The input end of the steam generator 3 is equipped with a water pipe 6 connected to the water tank 2 for drawing water from the water tank 2; the air outlet side of the fan 4 is equipped with an air pipe 7 connected to the water tank 2 for sending some gas into the water tank 2 to build up air pressure inside the water tank.
[0022] During operation, the blower 4 starts, drawing air in through the air inlet 52 on the ironing board 5. This creates a negative pressure at the air inlet 52, which effectively attracts clothing, overcoming the repulsive effect of the steam jet on the clothing. This allows the clothing to adhere tightly to the ironing board 5, thereby improving ironing efficiency and results. Simultaneously, the blower 4 sends a portion of the gas through the air pipe 7 to the top of the water tank 2, creating a positive pressure inside the tank. This pressure forces the water in the tank into the water pipe 6, thus providing a water source for the steam generator 3.
[0023] To enable the steam generator 3 to reliably draw water without a water pump, a key feature of this invention is that the lower end of the water pipe 6 is equipped with a liquid-absorbing funnel 61 located inside the water tank 2, and the liquid-absorbing funnel 61 is in an inverted funnel shape. Figure 2 , Figure 4 As shown, the suction funnel 61 is located at the bottom of the water tank 2, and can be slightly suspended or directly touching the bottom; the lower end of the air tube 7 extends to the top of the water tank 2. The suction funnel 61 adopts an inverted funnel-shaped structure, and its main function is to increase the water absorption area and reduce the air pressure required for the liquid to rise. The specific principle is as follows: 1) Increased water absorption area: The funnel-shaped structure can cover a larger water surface, allowing air pressure to act more effectively on the liquid surface, thereby increasing the possibility of water entering the water pipe 6.
[0024] 2) Reducing the air pressure required for liquid to rise: Compared to a straight pipe, the funnel-shaped structure allows the liquid to experience upward pressure over a larger area, making it easier to overcome gravity and flow upward. Therefore, even when the air pressure inside the water tank 2 is not high, it can ensure that water can smoothly enter the water pipe 6 to supply water to the steam generator 3.
[0025] In summary, the inverted funnel design of the suction funnel 61 optimizes the water absorption process, making it easier to occur. For example... Figure 2 , Figure 4As shown, to further improve water absorption efficiency, the lower periphery of the suction funnel 61 is provided with several suction holes 611. When the suction funnel 61 is placed on the bottom of the water tank 2, that is, when the suction funnel 61 touches the bottom, the suction holes 611 can still draw water from the bottom of the water tank, ensuring that the steam generator 3 can continuously obtain a sufficient water source. In addition, adjusting the height of the suction funnel 61 can adjust the gap between the bottom of the suction funnel 61 and the inner bottom surface of the water tank 2, thereby adjusting the maximum water absorption speed.
[0026] Preferred, such as Figure 5 As shown, a tube 612 is provided at the upper end of the suction funnel 61. The tube 612 is inserted into the lower end of the water pipe 6 from bottom to top, and an air inlet gap 613 is formed between the outer wall of the tube 612 and the inner wall of the lower end of the water pipe 6. According to Bernoulli's principle, when the water pipe 6 draws water, the air inlet gap 613 can draw in a certain amount of air, assisting the water to rise; conversely, when air enters the air inlet gap 613 due to air pressure, it will also accelerate the water absorption speed of the water pipe 6, further improving the water absorption efficiency. By adjusting the height of the suction funnel 61, the size of the air inlet gap 613 can be adjusted, thereby precisely adjusting the air intake speed and optimizing the water absorption effect.
[0027] To ensure that steam is evenly sprayed onto the clothing and to enhance the negative pressure adsorption effect, in this embodiment, the steam nozzle 51 is located in the central area of the ironing plate 5, and the air inlet 52 is located in the peripheral area of the ironing plate 5, surrounding the steam nozzle 51. In this way, steam can cover the entire ironing area, and the negative pressure adsorption force can be evenly applied to the clothing.
[0028] Considering that the air volume of the fan 4 may be too large, and in order to better control the air pressure inside the water tank 2, in this embodiment, the fan 4 is also provided with an exhaust port 11 on the air outlet side. Figure 2 , Figure 3 As shown, a baffle plate 12 is provided on the air outlet side of the blower 4, directly facing the blower 4. The upper ends of the exhaust port 11 and the air pipe 7 are both located on the side wall of the housing 1, with the upper end of the air pipe 7 closer to the baffle plate 12. The baffle plate 12 can block a portion of the airflow from blowing directly towards the exhaust port 11, thereby increasing the amount of gas entering the water tank 2 through the air pipe 7, increasing the air pressure inside the water tank 2, and ensuring the water supply to the steam generator 3.
[0029] To facilitate user grip and operation of the iron, in this embodiment, a handle 8 is provided at the bottom of the housing 1, a water tank 2 is connected to the lower end of the handle 8, and a water pipe 6 and an air pipe 7 pass through the inner cavity of the handle 8 and extend into the water tank 2. Figure 4 As shown. In order to prevent water leakage in water tank 2, in this embodiment, water tank 2 is a sealed box, and a water inlet 21 is provided on the top, and a sealing plug 22 is provided at the water inlet 21.
[0030] To facilitate assembly and maintenance and to form a good air duct, in this embodiment, the housing 1 includes a front cover 1a and an inner shell 1b located behind the front cover 1a. The steam generator 3 is located in the front cover 1a, and the inner cavity of the front cover 1a and the inner cavity of the inner shell 1b are connected to form an air duct. The fan 4 is located in the inner shell 1b.
[0031] In order to insulate against heat and prevent the iron shell from overheating and burning the user, in this embodiment, the inner shell 1b is covered with an outer shell 1c, and a gap is provided between the inner shell 1b and the outer shell 1c to form a heat insulation layer.
[0032] As can be seen from the above embodiments, this utility model, by adopting negative pressure adsorption, an inverted funnel-shaped liquid absorption structure, and a series of optimized designs, successfully solves the shortcomings of existing irons and provides an iron with high water absorption, good ironing effect, and high reliability.
