[0019] To further understand the content, features and effects of the present invention, the following embodiments are cited and described in detail with the accompanying drawings as follows: Such as Figures 1 to 6As shown in the figure, a steam generator of the present invention includes: a main 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 and is arranged inside the main body 1 for heating the water in the first heating chamber group and the second heating chamber group; a cover plate 3, which covers the first side of the main body 1 and is provided with a first water inlet joint 31 and a second water inlet joint 32. The first water inlet joint 31 is communicated with the first heating chamber group, and the second water inlet joint 32 is communicated with the second heating chamber group; an ironing board 4, which is arranged on the second side of the main body 1 and is provided with a plurality of steam holes 41 communicated with the first heating chamber group and a steam port 42 communicated with the second heating chamber group; a first sealing ring 11 is arranged between the cover plate 3 and the main body 1, and a second sealing ring 12 is arranged between the ironing board 4 and the main body 1. Compared with the prior art, in a steam generator of the present invention, by providing a second water inlet joint 32 on the cover plate 3, the second water inlet joint 32 is communicated with the second heating chamber group, and the ironing board 4 is provided with a steam port 42 communicated with the second heating chamber group. When water enters the second water inlet joint 32 and then enters the second heating chamber group and is heated by the heating element 2 to form steam and then is sprayed out through the steam port 42, the steam sprayed out from the steam port 42 has a fast speed, strong penetration power and high temperature, can iron relatively thick clothes, and the wrinkles of relatively thick clothes can also be ironed flat, with the advantages of wide application range and good user experience.
[0020] Further, as Figure 7 , Figure 8 and Figure 9 shown, the steam generator is provided with a three-way valve 5. The three-way valve 5 includes a valve body 53 having a first water outlet pipe 51 and a second water 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 a water inlet pipe 56, a water outlet 57, two sealing members 58 and a baffle 59. The two sealing members 58 are sleeved on the recess provided on the water inlet pipe 56 and are respectively located on both sides of the water outlet 57. The spring 54 is sleeved on the water inlet pipe 56. One end of the spring 54 elastically presses on the valve body 53, and the other end elastically presses on the baffle 59 of the valve core. The upper end of the push rod 55 abuts against the baffle 59. The first water outlet pipe 51 of the three-way valve is connected to the first water inlet joint 31, and the second water outlet pipe 52 is connected to the second water inlet joint 32. The two sealing members 58 are arranged on both sides of the water outlet 57 to ensure that the water flowing out from the water outlet 57 either flows into the first water outlet pipe 51 or flows into the second water outlet pipe 52.
[0021] Specifically, the first heating cavity group includes a first heating cavity 13, a second heating cavity 14, a third heating cavity 15, and a fourth heating cavity 16 that are sequentially connected to each other through through holes. The first heating cavity 13, the second heating cavity 14, the third heating cavity 15, and the fourth heating cavity 16 are connected to each other through through holes. Such a connection method is a prior art and will not be described in detail here. The first heating cavity 13 is connected to the first water inlet joint 31, and the fourth heating cavity 16 is connected to a plurality of steam holes 41. The second heating cavity group includes a fifth heating cavity 17 and a sixth heating cavity 18 that are sequentially connected to each other through notches. The sixth heating cavity 18 is connected to the steam port 42. The first heating cavity 13 and the fifth heating cavity 17 are adjacent. Both the first heating cavity 13 and the fifth heating cavity 17 are located inside the sixth heating cavity 18. The second heating cavity 14 is located inside the fourth heating cavity 16, and the sixth heating cavity 18 is located inside the third heating cavity 15. The first heating cavity 13, the second heating cavity 14, the third heating cavity 15, the fifth heating cavity 17, and the sixth heating cavity 18 are located on the first side of the body 1, and the second heating cavity 14 and the fourth heating cavity 16 are located on the second side of the body 1. Such a layout of the first heating cavity 13, the second heating cavity 14, the third heating cavity 15, the fourth heating cavity 16, the fifth heating cavity 17, and the sixth heating cavity 18 can minimize the overall volume of the steam generator, effectively reduce the volume of the ironing machine, and make the ironing machine more portable and flexible to use.
[0022] More specifically, the sixth heating cavity 18 is provided with a groove 181. 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 intersects with the groove 181 to form a gas storage cavity 6 that communicates with the sixth heating cavity 18. The groove 181 is provided with a plurality of air inlet grooves 182 that communicate the sixth heating cavity 18 and the gas storage cavity 6.
[0023] A steam guiding channel 7 is provided between the gas storage cavity 6 and the steam port 42. One end of the steam guiding channel 7 is connected to the gas storage cavity 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 member 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 member 36. The steam guiding cover 35 covers the steam guiding groove 34, and the third sealing member 71 is provided between the steam guiding cover 35 and the steam guiding groove 34. The gas storage cavity 6 can store steam inside to form a certain pressure, ensuring continuous steam output from the steam port 42.
[0024] Such as Figure 9 、 Figure 10As shown in the figure, the present invention also provides a steam ironing machine. Using the above-described steam generator, it further includes a housing 100, a water tank 101, a water pump 102, and a control circuit board 103. The steam generator, the water tank 101, the water pump 102, and the 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 water 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 the button 104 abuts against the lower end of the push rod 55.
[0025] The working principle of the steam ironing machine of the present invention is as follows: After the steam ironing machine is powered on, the control circuit board 103 controls the heating element 2 to be powered on and heated to preheat the steam generator. After heating to the set time, the control circuit board 103 then controls the water pump 102 to work. When the water pump 102 works, it will pump water from the water tank 101 and deliver it to the three-way valve. If the button 104 is not pressed, the valve core makes the water outlet 57 face the inlet of the first water outlet pipe 51 under the elastic force of the spring 54, and the water inlet pipe 56 is connected to the first water outlet pipe 51. The water pumped 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 cavity group through the first water inlet joint 31, be heated into steam by the heating element 2, and then be ejected from a plurality of steam holes 41. The steam ejected from the plurality of steam holes 41 is suitable for ironing relatively thin clothes or curtains.
[0026] If relatively thick clothes or curtains need to be ironed, just press the button 104. The button 104 will drive the push rod 55 to swing. The swing of the push rod 55 will overcome the elastic force of the spring 54 and make the valve core move as a whole in the direction of the valve body 53, so that the water outlet 57 faces the inlet of the second water outlet pipe 52, and the water inlet pipe 56 is connected to the second water outlet pipe 52. The water pumped by the water pump 102 from the water tank 101 will enter the water inlet pipe 56 and then flow into the second water outlet pipe 52 from the water outlet 57. The water flowing into the water outlet pipe 52 will enter the second heating cavity group through the second water inlet joint 32, be heated into steam by the heating element 2, and then be ejected from the steam port. If the button 104 is not pressed, the elastic force of the spring 54 makes the valve core reset as a whole, so that the water outlet 57 faces the inlet of the first water outlet pipe 51, and the water inlet pipe 56 is connected to the first water outlet pipe 51 again. During the use process, the user can switch at will according to the needs through the button 104, which has the advantages of good user experience and wide application range.
[0027] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, or improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
