Except for special description, the fixing may be non-detachable fixing manner such as welding, and may also be detachable fixing manner such as locking by screw.

Referring to fig. 1 to 9, the present embodiment provides an ultrasonic atomizing coating head 100 including a housing and an ultrasonic driver 3. Wherein, the shell is provided with a cavity, a liquid inlet channel 5, an air inlet channel 7 and a spraying channel 11, and the cavity is simultaneously communicated with the liquid inlet channel 5, the air inlet channel 7 and the spraying channel 11. The ultrasonic driver 3 is fixed in the cavity. Referring to fig. 6, as one possible example, the ultrasonic driver 3 includes a piezoelectric ceramic plate 22 and a support plate 23, the upper surface of the piezoelectric ceramic plate 22 is coated with a resist layer 21, and the lower surface of the piezoelectric ceramic is provided with electrodes for electrical connection with a controller. A support plate 23 (preferably a metal plate) is located at the lower side of the piezoceramic wafer 22 and is fixedly connected to the piezoceramic wafer 22 to improve the strength of the piezoceramic wafer 22.

When the ultrasonic atomization coating head 100 is used, liquid (namely dye liquid) enters a cavity through the liquid inlet channel 5 and covers the surface of the ultrasonic driver 3, the ultrasonic driver 3 generates high-frequency vibration to atomize the liquid on the surface into liquid drops, and meanwhile, gas enters the cavity through the gas inlet channel 7. The gas and the atomized liquid drops are mixed together to form a mist dye which is sprayed out through the spraying channel 11 and sprayed on the fabric, so that the dyeing function is realized. By making the ultrasonic driver 3 generate different ultrasonic intensities, the concentration of the sprayed dye can be controlled, and different printing and dyeing effects can be produced. As a preferable example, the ejection channel 11 is elongated.

As a possible example, the ultrasonic atomization coating head 100 further comprises a filter, which is installed at the liquid inlet channel 5 to filter large particulate matters in the liquid, so as to prevent impurities in the liquid from entering into the cavity.

As a possible example, a lyophobic layer (e.g., a resin composition lyophobic layer) is provided on the housing, and the lyophobic layer is coated at least on the inner wall of the ejection channel 11 to improve the fluidity of the liquid. As a preferable example, the lyophobic layer covers the cavity, the liquid inlet passage 5, the air inlet passage 7, and the ejection passage 11 at the same time.

Referring to fig. 9, as a possible example, in some special cases, such as when the viscosity of the liquid is high (e.g., glue), in order to improve the fluidity of the liquid, the ultrasonic atomizing coating head 100 further includes a heating device 31 (e.g., a resistive heating sheet), and the heating device 31 is fixed in the cavity. By heating, the viscosity of the liquid is reduced, so that better atomization can be realized, and the liquid can be sprayed on the fabric more uniformly.

The type of housing is various and can be selected by those skilled in the art according to the actual circumstances. Referring to fig. 1 to 5 and 7, as a possible example, in order to adjust the width of the ejection channel 11 to adapt to dyes with different viscosities, the housing includes an upper cover 1, a lower cover 2 and a gasket 9, the gasket 9 is sandwiched between the upper cover 1 and the lower cover 2, and the upper cover 1, the lower cover 2 and the gasket 9 are detachably and fixedly connected as a whole. The spraying channel 11 is formed by splicing the upper cover 1 and the lower cover 2, and a gap is arranged on the gasket 9 corresponding to the spraying channel 11. When the width of the ejection channel 11 needs to be adjusted, only the gaskets 9 with different thicknesses need to be replaced, and the method is simple and convenient.

Referring to fig. 1 to 5 and 9, as a possible example, the inlet passage 5 is provided on the lower cover 2 and the inlet passage 7 is provided on the upper cover 1.

Referring to fig. 1 to 3, as a possible example, the lower cover 2 is further provided with a liquid outlet channel 6, and the liquid in the cavity can flow out through the liquid outlet channel 6.

Referring to fig. 3-5 and 9, the cavities include, as one possible example, an air chamber 10, a reservoir chamber 4 and an atomization chamber 8. An air chamber 10 is located in the upper cover 1 and connected to the intake passage 7 for temporarily containing air. Liquid reserve room 4 and atomizer chamber 8 are located lower cover 2, can separate with the overflow weir between liquid reserve room 4 and the atomizer chamber 8, make the liquid in the liquid reserve room 4 reach in the overflow entering atomizer chamber 8 after the take the altitude. The liquid storage chamber 4 is connected with the liquid inlet channel 5 and is used for temporarily storing liquid flowing into the liquid inlet channel 5. The atomization chamber 8 is connected with the liquid storage chamber 4, and the ultrasonic driver 3 is positioned in the atomization chamber 8 to atomize the liquid flowing from the liquid storage chamber 4. The air chamber 10 is located above the atomizing chamber 8, and the ejection passage 11 is connected to both the atomizing chamber 8 and the air chamber 10 to eject air and the atomized liquid out of the ejection passage 11.

Referring to fig. 4 to 5, as one possible example, the side of the air chamber 10 close to the ejection channel 11 has a first inclined surface, and the side of the atomization chamber 8 close to the ejection channel 11 has a second inclined surface, and the first inclined surface and the second inclined surface form an angle with the tip end facing the ejection channel 11. The first inclined plane and the second inclined plane enable the cross section of the cavity to be in a contraction shape, and the flow speed can be accelerated under the condition that the flow rate is not changed.

Referring to fig. 8, as a possible example, when a plurality of ultrasonic atomizing coating heads 100 are used in combination (i.e., any two ultrasonic atomizing coating heads 100 are fixed relative to each other), the ultrasonic atomizing coating heads 100 may be arranged in a row along the X-axis (the spacing distance is smaller than the length of the ultrasonic atomizing coating head 100), a first row and a second row adjacent to each other along the Y-axis (the Y-axis is perpendicular to the X-axis), and the ultrasonic atomizing coating heads 100 of the first row and the ultrasonic atomizing coating heads 100 of the second row are alternately arranged in the X-axis direction. Compared with a row which is arranged in a continuous distribution mode, the arrangement mode can avoid the generation of missed blank areas on the X axis when the combined structure moves to coat along the Y axis by adjusting the spacing distance. When the ultrasonic atomization coating head 100 in the combined structure is detachable, the single ultrasonic atomization coating head 100 can be cleaned and maintained or replaced individually, so that the maintenance cost is reduced.
