[0029] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0030] like Figures 1 to 6 As shown, a steam generator of this utility model includes: a body 1, on which a first heating chamber group and a second heating chamber group are provided; a heating element 2, which is a heating tube disposed inside the body 1, for heating water in the first heating chamber group and the second heating chamber group; a cover plate 3, which covers the first side of the body 1, and is provided with a first water inlet connector 31 and a second water inlet connector 32, the first water inlet connector 31 being connected to the first heating chamber group and the second water inlet connector 32 being connected to the second heating chamber group; an ironing plate 4, which is disposed on the second side of the body 1, and is provided with a plurality of steam holes 41 communicating with the first heating chamber group and a steam outlet 42 communicating with the second heating chamber group; a first sealing ring 11 is provided between the cover plate 3 and the body 1, and a second sealing ring 12 is provided between the ironing plate 4 and the body 1. Compared with the prior art, the steam generator of this utility model has the advantages of having a second water inlet connector 32 on the cover plate 3, which is connected to the second heating chamber group, and a steam port 42 on the ironing plate 4 connected to the second heating chamber group. When water enters the second water inlet connector 32 and then enters the second heating chamber group, it is heated by the heating element 2 and becomes steam, which is then sprayed out through the steam port 42. The steam sprayed out from the steam port 42 has a fast speed, strong penetration and high temperature, and can iron relatively thick clothes. It can also iron out the wrinkles of relatively thick clothes, and has the advantages of wide applicability and good user experience.

[0031] Furthermore, such as Figure 7 , Figure 8 and Figure 9As shown, the steam generator is equipped with a three-way valve 5. The three-way valve 5 includes a valve body 53 with a first outlet pipe 51 and a second outlet pipe 52, a valve core, a spring 54, and a push rod 55. The push rod 55 is pivotally connected to the valve body 53. The valve core is provided with an inlet pipe 56, an outlet 57, two sealing elements 58, and a baffle 59. The two sealing elements 58 are sleeved on the recess provided on the inlet pipe 56 and are respectively located on both sides of the outlet 57. The spring 54 is sleeved on the inlet pipe 56. One end of the spring 54 presses against the valve body 53, and the other end presses against the baffle 59 of the valve core. The upper end of the push rod 55 abuts against the baffle 59. The first outlet pipe 51 of the three-way valve is connected to the first inlet connector 31, and the second outlet pipe 52 is connected to the second inlet connector 32. Two seals 58 are provided on both sides of the outlet 57 to ensure that the water flowing out of the outlet 57 either flows into the first outlet pipe 51 or into the second outlet pipe 52.

[0032] Specifically, the first heating chamber group includes a first heating chamber 13, a second heating chamber 14, a third heating chamber 15, and a fourth heating chamber 16 that are sequentially interconnected by through holes. These heating chambers are connected via through holes; this connection method is existing technology and will not be described in detail here. The first heating chamber 13 is connected to the first water inlet connector 31, and the fourth heating chamber 16 is connected to multiple steam holes 41. The second heating chamber group includes a fifth heating chamber 17 and a sixth heating chamber 18 that are sequentially interconnected by notches. The sixth heating chamber 18 is connected to a steam port 42. The first heating chamber 13 and the fifth heating chamber 17 are adjacent to each other, and both are located inside the sixth heating chamber 18. The second heating chamber 14 is located inside the fourth heating chamber 16, and the sixth heating chamber 18 is located inside the third heating chamber 15. The first heating chamber 13, the second heating chamber 14, the third heating chamber 15, the fifth heating chamber 17, and the sixth heating chamber 18 are located on the first side of the main body 1, and the second heating chamber 14 and the fourth heating chamber 16 are located on the second side of the main body 1. This arrangement of the first heating chamber 13, the second heating chamber 14, the third heating chamber 15, the fourth heating chamber 16, the fifth heating chamber 17, and the sixth heating chamber 18 minimizes the overall size of the steam generator, effectively reducing the size of the iron and making the iron lighter and more flexible to use.

[0033] More specifically, the sixth heating chamber 18 is provided with a groove 181, and the cover plate 3 is provided with an extension wall 33 that extends downward into the groove 181 to form a concave cavity. The concave cavity and the groove 181 intersect to form a gas storage cavity 6 that communicates with the sixth heating chamber 18. The groove 181 is provided with multiple air inlet slots 182 that connect the sixth heating chamber 18 and the gas storage cavity 6.

[0034] A steam guiding channel 7 is provided between the gas storage chamber 6 and the steam port 42. One end of the steam guiding channel 7 is connected to the gas storage chamber 6, and the other end is connected to the steam port 42. The cover plate 3 is provided with a steam guiding groove 34, a steam guiding cover 35, and a third sealing element 63. The middle part of the steam guiding channel 7 is composed of the steam guiding groove 34, the steam guiding cover 35, and the third sealing element 63. The steam guiding cover 35 covers the steam guiding groove 34, and the third sealing element 63 is located between the steam guiding cover 35 and the steam guiding groove 34. The gas storage chamber 6 can store steam and form a certain pressure inside, ensuring that the steam port 42 outputs continuous steam.

[0035] like Figure 9 , Figure 10 As shown, this utility model also provides a steam iron, which uses the above-mentioned steam generator and includes a housing 100, a water tank 101, a water pump 102 and a control circuit board 103. The steam generator, water tank 101, water pump 102 and control circuit board 103 are all installed in the housing 100. The water tank 101 is connected to the water pump 102. The control circuit board 103 is electrically connected to the water pump 102 and the heating element 2 respectively. The inlet pipe 56 of the three-way valve 5 is connected to the water pump 102. A button 104 is pivotally connected to the housing 100 and abuts against the lower end of the push rod 55.

[0036] The working principle of this steam iron is as follows: After the steam iron is powered on, the control circuit board 103 controls the heating element 2 to be powered on and heated, so that the steam generator is preheated. After heating for a set time, the control circuit board 103 controls the water pump 102 to work. The water pump 102 will draw water from the water tank 101 and deliver it to the three-way valve. If the button 104 is not pressed, the valve core will be aligned with the inlet of the first water outlet pipe 51 under the elastic force of the spring 54. The water inlet pipe 56 is connected to the first water outlet pipe 51. The water drawn by the water pump 102 from the water tank 101 will enter the water inlet pipe 56 and then flow into the first water outlet pipe 51 from the water outlet 57. The water flowing into the first water outlet pipe 51 will enter the first heating chamber group through the first water inlet connector 31 and be heated into steam by the heating element 2. The steam will then be sprayed out from multiple steam holes 41. The steam sprayed out from the multiple steam holes 41 is suitable for ironing thinner clothes or curtains.

[0037] For ironing thicker clothing or curtains, simply press button 104. Button 104 will drive push rod 55 to swing. The swing of push rod 55 will overcome the elastic force of spring 54, causing the valve core to move towards valve body 53. This aligns the outlet 57 with the inlet of the second outlet pipe 52, connecting the inlet pipe 56 to the second outlet pipe 52. Water pumped from water tank 101 by pump 102 will enter inlet pipe 56 and then flow from outlet 57 into the second outlet pipe 52. The water flowing into outlet pipe 52 will then enter the second heating chamber via second inlet connector 32, where it will be heated by heating element 2 into steam and ejected from steam outlet. If button 104 is not pressed, the elastic force of spring 54 will reset the valve core, aligning the outlet 57 with the inlet of the first outlet pipe 51, and connecting the inlet pipe 56 to the first outlet pipe 51 again. During use, users can switch freely according to their needs using button 104, offering a good user experience and wide applicability.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
