Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 5 As shown, the present invention provides a self-cleaning steam device for a clothing care machine, comprising a flow guide mechanism 1, which is arranged inside a main body mechanism 2, a scraper mechanism 3 is arranged inside the main body mechanism 2, and the flow guide mechanism 1 is located above the scraper mechanism 3;

[0024] The diversion mechanism 1 includes a first motor 101, the bottom of the first motor 101 is rotatably connected to a driving gear 102, the side of the driving gear 102 is meshed with a driven gear 103, and a number of diversion holes 104 are evenly provided on the driven gear 103. A diversion member 105 is provided above the driven gear 103, and a cavity 106 is provided inside the diversion member 105. A number of spray holes 107 are evenly provided on the side of the diversion member 105, and a number of water outlet holes 108 are evenly provided on the bottom of the diversion member 105. The size of the spray hole 107 is smaller than the size of the water outlet hole 108, and the size of the water outlet hole 108 is the same as the size of the diversion hole 104. The water outlet hole 108 and the diversion hole 104 are staggered.

[0025] The main body 2 includes a steam generator 201, a water inlet 202 is provided on the top of the steam generator 201, a filter component 203 is fixedly connected to the inside of the water inlet 202, two steam outlets 204 are provided on the top of the steam generator 201, a water outlet 206 is provided on the side of the steam generator 201, and an electronic valve 205 is provided between the two steam outlets 204 and the water outlet 206, a steam generating chamber 207 is provided inside the steam generator 201, a heater 208 is fixedly connected to the inner wall of the steam generator 201, the water inlet 202 is located between the two steam outlets 204, and an activated carbon layer and a filter cotton layer are provided inside the filter component 203.

[0026] The bottom of the first motor 101 is fixedly connected to the surface of the steam generator 201, the driving gear 102 penetrates the surface of the steam generator 201 and extends to the interior of the steam generator 201, the driving gear 102 is rotatably connected to the inner wall of the steam generator 201, the driven gear 103 is rotatably connected to the inner wall of the steam generating chamber 207, and the guide member 105 is fixedly connected to the inner wall of the steam generating chamber 207.

[0027] The scraper mechanism 3 includes a second motor 301, which is rotatably connected to a rotating shaft 302, and a plurality of connecting rods 303 are fixedly connected to the rotating shaft 302. The end of the connecting rod 303 away from the rotating shaft 302 is fixedly connected to a spiral scraper 304. There are two spiral scrapers 304, and the plurality of connecting rods 303 are evenly distributed on the surface of the rotating shaft 302. The second motor 301 is fixedly connected to the side of the steam generator 201 away from the water outlet 206. The rotating shaft 302 passes through the surface of the steam generator 201 and extends to the interior of the steam generating chamber 207. The rotating shaft 302 is rotatably connected to the inner wall of the steam generating chamber 207, and the surface of the spiral scraper 304 is against the inner wall of the steam generating chamber 207.

[0028] The above scheme is adopted: by starting the first motor 101 to rotate the driving gear 102, the driving gear 102 rotates and drives the driven gear 103 meshing with it to rotate 30 degrees, so that the guide hole 104 on the driven gear 103 and the water outlet hole 108 on the guide member 105 are offset from each other, and the water outlet hole 108 is blocked. At this time, after the water entering the water inlet 202 enters the cavity 106, the air pressure inside the cavity 106 increases due to the blockage of the water outlet 108, so that water is sprayed out from the spray hole 107, and the inner wall of the steam generating chamber 207 below the steam outlet 204 is flushed to remove the scale attached to this position, and the second motor 301 is started at the same time. The rotating shaft 302 rotates, and the rotation of the rotating shaft 302 drives the spiral scraper 304 to rotate through the connecting rod 303. The rotation of the spiral scraper 304 cleans the scale attached to the inner wall of the steam generating chamber 207, and moves toward the water outlet 206 along the rotation of the spiral scraper 304, and finally is discharged from the water outlet 206 with the water flow. The cooperation between the two can improve the self-cleaning effect and speed of the device and reduce the downtime of the steam device. At the same time, when water enters from the water inlet 202, it will first be filtered by the filter component 203 before entering the steam generating chamber 207, which can reduce impurities in the water and reduce the scale generated on the inner wall of the steam generating chamber 207.

[0029] The working principle and use process of the utility model: When the steam generator 201 is working, the positions of the guide hole 104 on the driven gear 103 and the water outlet hole 108 on the guide member 105 are as follows: Figure 5As shown, when water enters from the water inlet 202, it will first be filtered by the filter assembly 203 and then enter the steam generating chamber 207. At the same time, the heater 208 is started and the electronic valve 205 inside the steam outlet 204 is opened. At this time, part of the water will flow into the cavity 106 of the guide member 105, while the other part of the water will flow down along the surface of the guide member 105. Some of this part of the water will enter the cavity 106 along the spray hole 107 when passing through the spray hole 107. At this time, the water pressure inside the cavity 106 is relatively low, so most of the water inside the cavity 106 will flow into the steam generating chamber 207 through the water outlet 108 and the guide hole 104, and a small part will overflow from the spray hole 107. The diverted water is heated by the heater 208 to form steam and is discharged from the steam outlet 204 along the curvature of the inner wall of the steam generating chamber 207.

[0030] After working for a period of time, the first motor 101 is started to rotate the driving gear 102, and the rotation of the driving gear 102 drives the driven gear 103 meshing therewith to rotate 30 degrees, so that the guide hole 104 on the driven gear 103 and the water outlet 108 on the guide member 105 are offset from each other, blocking the water outlet 108, and at the same time closing the electronic valve 205 inside the steam outlet 204, opening the electronic valve 205 inside the water outlet 206, and turning off the heater 208. At this time, the water entering the water inlet 202 enters the cavity 106, and the cavity 106 is blocked because the water outlet 108 is blocked. The air pressure inside 06 increases, causing water to spray out from the nozzle 107, flushing the inner wall of the steam generating chamber 207 below the steam outlet 204, and removing the scale attached to this position. At the same time, the second motor 301 is started to rotate the rotating shaft 302. The rotation of the rotating shaft 302 will drive the spiral scraper 304 to rotate through the connecting rod 303, and the rotation of the spiral scraper 304 will clean the scale attached to the inner wall of the steam generating chamber 207, and move toward the water outlet 206 along the rotation of the spiral scraper 304, and finally be discharged from the water outlet 206 with the water flow, thereby achieving a self-cleaning effect.
