Water can enter the air dissolving cavity 131 through the water inlet 141, the air in the air dissolving cavity 131 is excited and dissolved in the air dissolving cavity 131, hundreds of millions of micro-bubble water can be formed through the cavitation channel 220 of the cavitation part 2 under high pressure, a large amount of micro-bubble water formed through the cavitation channel 220 of the cavitation part 2 flows into the water outlet cavity 132 and is finally sprayed out through the plurality of spraying holes 1211 on the spraying plate, and the body and articles (such as clothes, tableware, fruits and vegetables) can be cleaned.

For example, when the spraying device 100 is used in a shower system, the spraying device 100 may be connected to a water heater through a pipeline, warm water of the water heater enters the dissolved air cavity 131 of the shower head 1 through the pipeline connected between the water heater and the spraying device 100 through the water inlet 141, the dissolved air cavity 131 is excited to dissolve air in the dissolved air cavity 131, hundreds of millions of micro-nano bubble water may be formed through the cavitation channel 220 of the cavitation member 2 under high pressure, and finally the micro-nano bubble water is ejected out through the water outlet to clean the body, a large amount of micro-nano micro-bubble water contacts with the surface of the body, bubbles collapse to generate huge energy to take away the stains, and the micro-nano bubbles generate radicals to attack the stains, so that the stains are decomposed and fall off, while the spraying function is realized, the cleaning and decontamination capabilities of the spraying device 100 may be improved, for example, the capability of cleaning the skin may be improved.

Optionally, the cavitation channel 220 may be formed as a venturi channel, and in the process that water flow with a large amount of air dissolved flows through the cavitation channel 220, since the flow area of the cavitation channel 220 is first reduced and then increased, a great pressure difference is formed at two ends of the cavitation channel 220, a pressure at a cavitation inlet 22011 of the cavitation channel 220 is large, and a pressure at a cavitation outlet 122031 of the cavitation channel 220 is small, which is equivalent to extruding water flow with a large cross section into the cavitation channel 220 with a small cross section, the velocity of the water flow entering the cavitation channel 220 under high pressure driving will rapidly increase, and since the flow area of the cavitation channel 220 is first reduced and then increased, the flow velocity and the pressure of the water flow change accordingly, and the solubility of the air in the water will decrease, so that the air will be separated out in the form of micro bubbles, and a large amount of. Therefore, the cavitation channel 220 is set as a venturi channel, so that the cavitation effect of the cavitation channel 220 can be further improved, micro bubbles with smaller volume and more quantity can be formed, and the cleaning and decontamination capability can be further improved.

For example, in the example of fig. 22, the cavitation channel 220 is a venturi channel, the cavitation channel 220 includes a tapered section 2201, a throat section 2202, and a diverging section 2203 connected in series, the tapered section 2201 having a cavitation inlet 22011, the diverging section 2203 having a cavitation outlet 122031, the flow area of the tapered section 2201 gradually decreasing in a direction from the cavitation inlet 22011 to the cavitation outlet 122031, and the flow area of the diverging section 2203 gradually increasing in a direction from the cavitation inlet 22011 to the cavitation outlet 122031, wherein the flow area of the throat section 2202 is the smallest. Wherein, the diameter range of the cavitation inlet 22011 can be 1.5-2.5mm, the diameter range of the throat section 2202 can be 0.5-1.2mm, and the diameter range of the cavitation inlet 22011 can be 1.2-2.0mm, so that the cavitation part 2 not only can produce micro-bubble water with richer micro-bubble content, but also the flow velocity of water flow in the cavitation part 2 is more moderate, and the blocking risk of the cavitation channel 220 can be reduced.

Alternatively, the cavitation column 22 may be one, and the cavitation column 22 may be plural. When there is one cavitation column 22, the cavitation column 22 is disposed adjacent to the bottom of the mounting plate 21; when the number of the cavitation pillars 22 is plural, each cavitation pillar 22 is formed with a cavitation channel 220, wherein at least one cavitation pillar 22 is disposed adjacent to the bottom of the mounting plate 21, for example, one cavitation pillar 22 is disposed adjacent to the bottom of the mounting plate 21, or each cavitation pillar 22 is disposed adjacent to the bottom of the mounting plate 21. Therefore, the cavitation channel 220 is close to the bottom of the cavitation piece 2, water flow entering the gas dissolving cavity 131 through the water inlet 141 is easy to concentrate at the bottom of the gas dissolving cavity 131 under the action of gravity, and micro-bubble water can be discharged through the cavitation channel 220 to form no matter how fast the water flow is or how much water is accumulated in the gas dissolving cavity 131, and the residual water in the gas dissolving cavity 131 can be reduced.

Optionally, a plurality of spaced-apart cavitation channels 220 may be disposed on the cavitation column 22 to improve the bubble-making capability of the cavitation member 2, so that a large amount of micro-bubbles are formed in a unit time. For example, the total number of cavitation passages 220 may be 3-12, and the cavitation passages 220 are the key to the generation of micro-bubbles by the shower device 100. The number of the cavitation channels 220 is too large, the pressure of the gas dissolving cavity 131 is too small, and the condition of generating micro-nano bubbles is not enough; the number of cavitation passageway 220 is too little, and the effectual of producing micro-nano bubble, nevertheless go out water fewly, can't satisfy the demand of washing such as shower, through setting up the number of cavitation passageway 220 at 3-12, can satisfy the condition that the microbubble produced simultaneously and can satisfy the demand of washing such as shower again.

For example, in the example of fig. 1, 4 and 19, the cavitation member 2 includes a mounting plate 21 and a cavitation column 22 provided on the mounting plate 21, the cavitation column 22 being one and provided adjacent to the bottom of the mounting plate 21, the cavitation column 22 having 5 cavitation channels 220 formed thereon. When the cavitation member 2 is used for the spray device 100, the cavitation member 2 is arranged in the spray header 1 of the spray device 100, water flow entering the containing cavity 13 of the spray header 1 through the water inlet 141 is easy to concentrate at the bottom of the air dissolving cavity 131 under the action of gravity, so that water flow dissolved with a large amount of air and accumulated at the bottom of the air dissolving cavity 131 can be subjected to cavitation action through the cavitation channel 220 to form micro-bubble water, even when the water amount in the air dissolving cavity 131 is small, the water flow dissolved with a large amount of air is still accumulated at the bottom of the air dissolving cavity 131, so that no matter how fast the water flow is or the amount of water accumulated in the air dissolving cavity 131, the micro-bubble water can be discharged through the cavitation channel 220 to form the micro-bubble water, and the residual water amount in the air dissolving cavity 131 can be reduced.
