The internal cavity of the shell wraps the internal components of the garment steamer. The user holds the handle part 2 and moves the mist outlet 6 at the mist outlet end of the spray part 1 close to the clothes to be ironed and performs corresponding operations to complete the ironing of the clothes.

[0048] In an embodiment of the present invention, a garment steamer includes a heat mixing box 3 disposed at the mist outlet, and a steam generator 4 and an atomizer 5 connected to the heat mixing box, respectively. The steam generator 4 is configured to generate high-temperature water mist, and the atomizer 5 is configured to generate room-temperature water mist. The high-temperature water mist generated by the steam generator 4 and the room-temperature water mist generated by the atomizer 5 are injected into the heat mixing box 3 for convective heat exchange to form a mixed water mist having a target ironing temperature. The mixed water mist is then ejected through a mist outlet 6 disposed at the front end of the heat mixing box 3 to iron the target garment. The heat mixing box 3, steam generator 4, and atomizer 5 of the garment steamer are all disposed within the spray section 1.

[0049] In an embodiment of the present invention, the material of the clothing can be identified by the user's own judgment. The temperature adjustment position of the garment steamer will recommend the user to set the target ironing temperature of the mixed water mist to be sprayed through a prompt mark. The user can also set the target ironing temperature as needed. Generally, the ironing temperature required for cotton and linen clothing is 155~185℃, the ironing temperature required for polyester is 140~160℃; the ironing temperature required for wool and silk fabrics is 120~160℃; the ironing temperature required for leather is 80℃; the ironing temperature required for spandex is 45~65℃.

[0054] Furthermore, to facilitate detection of water level changes in the first water tank 8, a first water level detection device is provided in the first water tank 8 for detecting the water level therein. When the water level in the first water tank 8 reaches a preset total water shortage, the atomizing device 4 and the steam generating device 5 are controlled to stop operating, and the user is prompted to add water. It should be noted that the first water tank 8 in this embodiment of the present invention is detachably connected to the housing, making it convenient for the user to remove and refill the first water tank 8.

[0055] Furthermore, a first check valve 11 is provided on the second water channel 10, and the control device of the hanging iron can also adjust the water supply of the steam generating device 4 by controlling the opening of the first check valve 11 to adjust the mist production of the high-temperature water mist of the steam generating device 4.

[0056] Furthermore, the atomizing device 5 of the embodiment of the present invention includes an atomizing plate 15 and a second water tank 14 . The second water tank 14 is used to supply water to the atomizing plate 15 so that the atomizing plate 15 generates water mist at room temperature.

With the development of science and technology, the material of the clothing can also be obtained by obtaining the texture features of the surface of the clothing based on big data, machine learning and other related technologies, and the present invention is not limited to this.

[0060] It should be noted that the target ironing temperature of the mixed water mist required for the target clothing of the garment steamer of the present invention can also be achieved by the user manually inputting the target clothing material or the target ironing temperature.

[0061] Furthermore, a preferred embodiment of the present invention further includes a display device disposed on the housing for displaying the real-time temperature of the mixed water mist and the target ironing temperature.

[0065] S2. Searching for a heat exchange ratio parameter corresponding to the target ironing temperature according to a preset correspondence table, where the heat exchange ratio parameter is a mixing ratio of the mist production of the normal temperature water mist and the mist production of the high temperature water mist of the garment steamer;

[0066] In this embodiment of the present invention, the system pre-stores the mixing ratio of ambient temperature mist to high temperature mist, corresponding to the target ironing temperature to be sprayed. Once the target ironing temperature is known, the corresponding ambient temperature and high temperature mist production quantities can be quickly determined through table lookup. Accordingly, the ambient temperature and high temperature mist production quantities are adjusted accordingly based on the ironing level set by the user.

[0067] S3.

In this case, the mist output of the steam generator 4 can be increased, the mist output of the atomizing device 5 can be decreased, or both can be increased and decreased. The greater the absolute value of the difference, the greater the adjustment range.

The method according to claim 10, characterized in that The controlling of the mist production of the steam generating device and the atomizing device of the garment steamer according to the heat exchange ratio parameter includes: The water supply of the steam generating device of the garment steamer and the atomizing power of the atomizing device are controlled so that the steam generating device and the atomizing device emit mist according to the heat exchange ratio parameter.

13. The method according to any one of claims 10 to 12, characterized in that: After obtaining the target ironing temperature of the garment steamer, the method further includes: determining whether the target ironing temperature is greater than or equal to the temperature of the high-temperature water mist generated by the steam generating device; If the target ironing temperature is greater than or equal to the temperature of the high-temperature water mist generated by the steam generating device, the steam generating device is controlled to work alone.

14. The method according to claim 11 or 12, characterized in that The method further comprises: Get the real-time temperature of the mixed water mist; comparing the difference between the real-time temperature and the target ironing temperature; The mist production amount of the steam generating device and / or the atomizing device is adjusted according to the difference between the real-time temperature and the target ironing temperature, so that the mixed water mist reaches the target ironing temperature.

15. The method according to claim 10, characterized in that The method further comprises: Obtaining water amount information in the atomization device; When the water volume information reaches a preset water shortage volume, the steam generating device and the atomizing device are controlled to stop working, and water is injected into the atomizing device.

16. The method according to claim 10, characterized in that The method further comprises: The material of the target clothes to be ironed is identified, and the target ironing temperature of the mixed water mist to be sprayed is determined according to the material of the target clothes to be ironed.
