In some embodiments, as shown in fig. 3, the barrel 13 further includes an inlet channel 131 and an inlet channel 132. The liquid inlet channel 131 is communicated with the second channel 12, and the liquid inlet channel 131 is used for guiding the second medium to the second channel 12; the inlet channel 132 communicates with the first inlet 201 of the first channel 20, the inlet channel 132 being adapted to leading the first medium into the first channel 20. As shown in fig. 3, the liquid inlet channel 131 is connected to one end of the second channel 12 far from the first liquid inlet channel 23, that is, the second medium guided in the liquid inlet channel 131 enters the second channel from one end of the second channel, and one end of the liquid inlet channel 131 connected to the second channel is far from the first liquid inlet channel 23 in the axial direction. The embodiment of the utility model provides a position department that lid 14 and barrel 13 are connected has certain clearance, and the outside gas of nozzle device 100 can be followed clearance department and got into in second passageway 12, and in the second medium in the inlet channel 131 can rush into second passageway 12 according to certain frequency clearance, the second medium can impact the gas that the second passageway 12 was interior and make the second medium disperse into less liquid drop at second passageway 12 to the realization is atomized in advance in the second passageway. The embodiment of the utility model provides a keep away from first inlet channel 23 with the hookup location of inlet channel 131 and second passageway, can prolong the gas storage volume in the second passageway to improve the time of second medium preatomization in the second passageway.

The embodiment of the present invention also provides a laundry treating apparatus, as shown in fig. 6, which includes the nozzle device 100 and the front supporter 200 according to any of the above embodiments, and the front supporter 200 is used for mounting the nozzle device 100. As shown in fig. 6, the laundry treating apparatus further includes a tub 700, the tub 700 being disposed at a rear side of the front supporter 200, and a receiving chamber 701 for receiving laundry with dry cleaning being provided in the tub 700. The nozzle device 100 may spray the dry-cleaning solvent atomized by the impact of the air onto the surface of the clothes in the receiving chamber 701, so that the dry-cleaning solvent may be contacted with and dissolved in the stains on the surface of the clothes, thereby performing dry-cleaning on the clothes in the receiving chamber. The embodiment of the utility model provides a through setting up nozzle device on the fore-stock body for nozzle device can realize the modularization production with the fore-stock body, is favorable to reducing nozzle device's the assembly degree of difficulty, and is favorable to improving clothing treatment facility's compact structure degree, has improved the feasibility and the reliability of fore-stock body and the product volume production that nozzle device formed, and the product of being convenient for is after sale maintenance. Just the utility model discloses nozzle device among the clothing treatment facility is through setting up the reducing section in the second passageway, is favorable to coming the flow velocity, pressure and the flow of the second medium of flow in the control second passageway through the parameter that changes the reducing section, and the structural parameter of this reducing section is mainly the size through the external dimension that changes the core or the first holding tank, compares in the size that changes first passageway and second passageway junction, the utility model discloses the embodiment is simple reliable to the control mode of the structural parameter of reducing section, is favorable to reducing the degree of difficulty of processing and reduction in manufacturing cost, and has reduced the flow control degree of difficulty that the second medium enters into in the first passageway to be favorable to improving the atomizing efficiency of second medium, and then improve the even degree that dry-cleaning solvent sprays on the clothing, improve the cleanliness factor of dry-cleaning.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
