The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] like Figures 1 to 4 As shown, an ultrasonic dust removal head includes a dust removal head 1, a left sealing plate 2, a right sealing plate 3 and a blowing head 4, one end of the dust removal head 1 is connected to the left sealing plate 2, the other end of the dust removal head 1 is connected to the right sealing plate 3, the blowing head 4 is connected to the right sealing plate 3, and the blowing head 4 is connected to the dust removal head 1 through the right sealing plate 3, the dust removal head 1 includes a shell 5, a partition baffle 6 and a support base 7, the partition baffle 6 is symmetrically arranged in the shell 5, the support base 7 is located at the bottom of the shell 5, and the shell 5, the partition baffle 6 and the support base 7 are integrally formed;

[0025] The partition baffle 6 includes a transverse plate 8 and a side plate 9, one end of the transverse plate 8 is connected to the inner side of the outer shell 5, and the other end thereof is connected to the side plate 9, and the other end of the side plate 9 is connected to the support base 7. A positive pressure air inlet cavity 10 is formed between the transverse plate 8 and the outer shell 5, a negative pressure cavity 11 is enclosed between the transverse plate 8, the side plate 9, the support base 7 and the outer shell 5, and an air collecting cavity 12 is enclosed between the two side plates 9 and the support base 7, and the air collecting cavity 12 is communicated with the positive pressure air inlet cavity 10.

[0026] like Figure 3 and Figure 4 As shown, the support base 7 includes a negative pressure base 13 and an air collecting base 14, the negative pressure base 13 is symmetrically arranged at both ends of the air collecting base 14, a negative pressure port 15 is provided on the negative pressure base 13, and the negative pressure port 15 is communicated with the negative pressure chamber 11, and a slit 16 is provided on the air collecting base 14, and the slit 16 is communicated with the air collecting chamber 12. The negative pressure base 13 and the air collecting base 14 are integrally formed. The width of the negative pressure port 15 is greater than the width of the slit 16, which is conducive to quickly sucking away the rushed dust. The width of the slit 16 in this embodiment can be 0.1mm-1.5mm, preferably 0.3mm, 0.5mm, 0.7mm or 1mm.

[0027] It should be noted that the gas in the positive pressure air inlet chamber 10 is accelerated into the air collecting chamber 12, and the gas is accelerated from the air collecting chamber 12 through the slit 16 and impacts the surface of the product to be dusted. As the gas is compressed, accelerated and passes through the slit 16, ultrasonic waves are generated. The ultrasonic waves are transmitted to the surface of the dust removal product through the gas coming out of the slit 16 to destroy the adhesion of the dust, so that the dust is separated from the product surface, and then the dust is driven by the reflection of the ultrasonic wave. The moving dust is instantly sucked away by the negative pressure chamber 11 through the negative pressure port 15, thereby achieving the dust removal effect.

[0028] It should be further explained that, in this embodiment, an ultrasonic resonator (not shown) may be installed in the slit 16. When the gas passes through the resonant cavity generated in the ultrasonic resonator, the adhesion of the dust may be further destroyed.

[0031] like Figure 4 As shown, the side plate 9 is tilted so that the distance between the two side walls of the gas collecting chamber 12 gradually decreases from top to bottom. The positive pressure gas passing through the gas collecting chamber 12 will accumulate energy as the distance between the side walls decreases, so that the gas will flow faster and more powerfully when rushing out of the slit 16, and can better act on the dust on the surface of the dust removal product.

[0032] like Figure 4 As shown, the positive pressure air inlet cavity 10 is located above the air collecting cavity 12 , and the negative pressure cavity 11 is located on both sides of the air collecting cavity 12 .

The utility model uses internally circulated clean air as a medium, which will not destroy the air balance of the clean workshop, avoid pollution, and has a compact and closed design to ensure a good dust removal environment.

[0037] like Figures 1 to 4 As shown, the working principle of the utility model is as follows:

[0038] The positive pressure tube 21 generates pressurized gas, which passes through the positive pressure air inlet chamber 10 and the air collecting chamber 12 and then enters the slit 16. When the gas comes out of the slit 16, ultrasonic waves are generated, which act on the surface of the product to be dusted through the slit 16, so that the dust on the surface of the product is free in the air; then the dust enters the negative pressure chamber 11 through the two negative pressure ports 15, and then is sucked into the dust removal main equipment through the negative pressure tube 22 for dust removal, thereby achieving the dust removal effect.
