Compared with the prior art, the embodiment has the dry ironing mode, the steaming ironing mode and the mixed ironing mode, is flexible to use, can perform more targeted treatment on different cloth and clothing conditions, and specifically:

When the compact garment steamer is in a dry ironing mode, the controller controls the water pump 4 and the steaming electric heating element 201 to be turned off, the dry ironing electric heating element 9 is turned on, the dry ironing electric heating element 9 supplies heat to the iron bottom plate 12 directly or indirectly, the iron bottom plate 12 heats and burns, the steam outlet 1201 does not spray steam, and press type dry ironing can be performed on cloth and clothes;

In practical product design, the three modes of this embodiment may be selected and switched by setting a button control panel, a touch control panel, a voice setting module, etc., so that a person skilled in the art may optionally add conventional components such as a display screen, a temperature sensor, a power module, etc., which are conventional in the art, and will not be described in detail.

On the other hand, the embodiment forms a high-pressure driving force for conveying steam through the water pump 4, and the design of a pressure cabin with a relatively large volume in the existing garment steamer product is canceled, so that the embodiment is small in volume and convenient to carry, and the steam range of the embodiment can reach more than 2 meters.

The steaming and ironing electric heating element 201 and the dry ironing electric heating element 9 may be metal electric heating tubes, electric heating films, electric heating wires, PTC heating plates, etc., without particular limitation. In particular to the embodiment, the steaming and ironing electric heating element 201 is an electric heating metal tube, and the dry ironing electric heating element 9 is a PTC heating plate (with a temperature regulation range of 80-200 ℃).

Because the water flow speed of high-pressure conveying is high, in order to further improve the vaporization effect of the embodiment on water, the top of the steaming and scalding electric heating element 201 of the embodiment is overlapped with the vaporization elbow pipe 2 and forms heat conduction contact, and the vaporization elbow pipe 2 is respectively communicated with the water pump 4 and the steam cavity A. The purpose of the vaporizing elbow 2 is to pre-treat the water, i.e., to initially vaporize the water to form a vapor mixture, which is then delivered to the vapor chamber a for complete or substantially complete vaporization.

In this embodiment, the top surface of the soleplate 12 is provided with a cavity structure, which is a bottom cavity B, and the bottom cavity B is communicated with the steam cavity a.

The top plate of the iron soleplate 12 is provided with a heat conducting plate shell 10 with an open bottom and good heat conductivity, the heat conducting plate shell 10 covers all the steam outlet holes 1201, and the heat conducting plate shell 10 and the iron soleplate 12 are surrounded to form the bottom cavity B.

The steam cavity A comprises an upper heat conducting cavity shell 6 and a lower heat conducting cavity shell 8 which are good in heat conductivity.

A one-way valve 3 is arranged between the water pump 4 and the vaporizing elbow pipe 2 to avoid backflow.

The vaporizing elbow pipe 2, the steaming and ironing electric heating element 201, the upper heat conducting cavity shell 6, the lower heat conducting cavity shell 8, the dry ironing electric heating element 9, the heat conducting plate shell 10 and the iron bottom plate 12 are sequentially stacked from top to bottom, and the steaming and ironing electric heating element 201 can supply heat for the vaporizing elbow pipe 2 and the steam cavity A at the same time; the dry ironing electric heating element 9 can provide heat for the steam cavity A and the heat conducting plate shell 10 at the same time, and the heat conducting plate shell 10 conducts heat to the iron bottom plate 12.

The above-mentioned stacked arrangement makes the structure of this embodiment compact, the product pursuit of small-size of laminating, can utilize the heat of the heating element of the electric heating element to the maximum extent at the same time; in addition, since the steam chamber a is required to completely vaporize or substantially completely vaporize the water-air mixture, it is necessary to ensure that the steam chamber a has the most sufficient heat, and the steam-ironing electric heating element 201 and the dry-ironing electric heating element 9 are respectively disposed on the upper and lower sides of the steam chamber a.

The evaporation bent pipe 2, the steam cavity A and the bottom cavity B are sequentially communicated, the evaporation bent pipe 2 is used for processing water into a steam mixture to finish preliminary evaporation, the steam cavity A is used for completely evaporating the steam mixture or basically completely evaporating the steam mixture, the bottom cavity B is used for keeping the state of completely evaporating the water or completely evaporating the residual extremely small amount of steam mixture, and the water gradually realizes complete evaporation in the conveying process, so that the embodiment has sufficient steam output and improves the processing effect and the processing efficiency on cloth of clothes.

Another common problem that is considered to exist with existing garment steamer products is: after the garment steamer is closed after each use, unreleased steam exists in the steam cavity A and the bottom cavity B, the unreleased steam can be re-condensed into a small amount of water in the steam cavity A and the bottom cavity B along with the reduction of the temperature after the garment steamer is closed, and when the garment steamer is opened again, condensed water formed by the last time of closing is easy to spray out along with newly formed steam, particularly the bottom cavity provided with the steam outlet 1201, so that the steam cavity A and the bottom cavity B of the embodiment are designed into flat cavities, namely the horizontal area of the cavities is maximized as much as possible, and when the garment steamer is opened again, the condensed water formed by the last time of closing is quickly vaporized again due to the large contact area with the cavity wall, and the problem of water drop spraying when the garment steamer is just started is reduced as much as possible.

Specifically, a heat transfer plate 202 is disposed between the vaporizing elbow 2 and the steaming and scalding electric heating element 201 (electric heating metal tube), the vaporizing elbow 2 and the heat transfer plate 202 are made of metal with good thermal conductivity, the vaporizing elbow 2 is tightly attached to and welded to the top surface of the heat transfer plate 202, and the bottom surface of the heat transfer plate 202 is welded to the steaming and scalding electric heating element 201.

The pipe orifices at the two ends of the vaporizing elbow 2 exceed the edges of the heat transfer plates 202, the rest pipe sections of the vaporizing elbow 2 are bent for a plurality of times along the horizontal plane on the top surface of the heat transfer plates 202 and do not exceed the edges of the heat transfer plates 202, the contact heat transfer area is expanded as much as possible, meanwhile, the stroke of water in the vaporizing elbow 2 is prolonged, and the primary vaporizing effect is ensured.

The pipe orifices at two ends of the vaporizing elbow pipe 2 are provided with an inlet pipe orifice 204 and an outlet pipe orifice 203, the inlet pipe orifice 204 is directly or indirectly communicated with the water pump 4, and the outlet pipe orifice 203 is directly or indirectly communicated with the steam cavity A.

The heat transfer plate 202 has a square body shape with a first side, a second side, a third side, and a fourth side connected in sequence. The vaporizing elbow 2 is provided with an L-shaped section 205, a first U-shaped section 206, a second U-shaped section 207 and an I-shaped section 208 in sequence from the inlet pipe orifice, and the tail of the I-shaped section 208 is used as the outlet pipe orifice 203, and the sections are in smooth transition.

The vaporization elbow pipe 2, the steam cavity A and the bottom cavity B which are communicated are set as a communicated group cavity. Along with the increase of the service time, scale can be accumulated on the structures with smaller widths such as the steam outlet holes, even cause blockage, and the pressure in the communicating group cavity is increased, so that the communicating group cavity is communicated with the pressure sensing protection module 5. The pressure-sensitive protection module 5 comprises at least one micro switch 501 and an elastic touch piece (such as a spring, an elastic sheet, etc.) which is installed corresponding to the micro switch 501, wherein the micro switch 501 is electrically connected with the controller;

the elastic touch member is driven to deform by the air pressure in the communication group cavity, if the air pressure in the communication group cavity reaches a preset value, the deformation amount of the elastic touch member is enough to touch the micro switch 501, the micro switch 501 sends a signal to the controller, and the controller controls the power supply to be cut off, so that a user is reminded of suspending the use of the air pressure to be reduced or checking whether scale is accumulated.

In this embodiment, the pressure-sensitive protection module 5 includes two micro-switches 501, two elastic touch members corresponding to the micro-switches 501, and an alarm, where the alarm is electrically connected to the control board.

The air pressure in the communicating group cavity drives any one of the elastic touch pieces to deform or drives two elastic touch pieces to deform at the same time, and the principle of safe power failure is the same as that described above.

Any one of the micro switches 501 is rusted and damaged, and the controller starts the alarm.

In this embodiment, although the waterproof treatment of the communicating group cavity is performed, each component may not be contacted with a small amount of water vapor, the micro switch 501 may be damaged by rusting along with the increase of the service time, the sensitivity is reduced, the resistance is further increased, the micro switch 501 with the increased resistance triggers the controller to start the alarm, and the user is reminded to pay attention to repair or replacement of the garment steamer.

Specifically, the warning device may be a buzzer, a warning lamp, etc., and the type, the model and the starting of the warning device are all conventional technologies, without special limitation.

In addition, considering that the scene of ironing clothes often happens a period of time before a user goes out of a gate in an important occasion, and considering that the probability of simultaneously rusting and damaging two micro switches 501 is extremely low, the embodiment sets two micro switches 501, even if one micro switch 501 is warned to be damaged in the ironing process, after the air pressure is reduced or scales are cleaned, the embodiment is restarted, the other micro switch 501 can still ensure the safe power-off function, so that the user can at least safely finish the clothes being ironed at the moment, the user is not delayed to attend the important occasion, and then the embodiment is returned to the factory for maintenance or re-purchase.

Specifically, the pressure sensing protection module 5 further includes a fixing sleeve 502, one side of the fixing sleeve 502 is provided with an interface 502a for communicating the communicating group cavity, and two elastic touch members are installed on the opposite side.

The pressure sensing protection module 5 and the water pump 4 are respectively arranged at two sides of the communication cavity group. Specifically, the top surface of the iron soleplate 12 is provided with an annular heat insulation pad 13, the heat insulation pad 13 surrounds the bottom cavity B, and the shell 11, the water pump 4 and the pressure sensing protection module 5 are all installed and fixed on the heat insulation pad 13, so as to avoid directly contacting with the high-temperature iron soleplate 12.
