As shown in fig. 1-10, an atomizing spray device, with the direction of spray of the atomizing spray device as the front end (for the sake of clarity only and without limiting the actual orientation), comprises: a first joint 1, a second joint 2, a third joint 3, a spray head 5 and a gasket 6. The rear end of the first connector 1 is provided with a water inlet hole 11, the front end of the first connector 1 is provided with a first accommodating groove 12, the water inlet hole 11 is communicated with the first accommodating groove 12 through a first water inlet channel 13, the side surface of the first connector 1 is provided with an air inlet hole 14, and the air inlet hole 14 is communicated with the first accommodating groove 12 through a first air inlet channel 15. The second connector 2 is arranged in the first accommodating groove 12, and a gasket 6 is arranged between the bottom of the first accommodating groove 12 and the rear end face of the second connector 2. The third joint 3 is connected to the front end of the second joint 2. The rear end of the spray head 5 is provided with a cavity 51, the front end of the spray head 5 is provided with a nozzle 52, the cavity 51 is communicated with the nozzle 52 through an atomization cavity 54, the rear end of the spray head 5 is connected with the second connector 2, and the third connector 3 is positioned in the cavity 51. The fourth joint 4 is sleeved on the outer side of the spray head 5, and the fourth joint 4 is in threaded connection with the side wall of the first accommodating groove 12 so as to fix the first joint 1, the second joint 2, the third joint 3 and the spray head 5 with each other. In this embodiment, the first connector 1, the second connector 2, the third connector 3 and the spray head 5 are all made of PEEK material, the PEEK material is wholly named polyether-ether-ketone, and has physical and chemical properties such as high temperature resistance, chemical corrosion resistance, toughness and rigidity, and fatigue resistance to alternating stress is particularly outstanding in plastic materials, so that the spray-washing device is very suitable for working conditions such as precise surface treatment (chemical liquid is often used in precise surface treatment), and meanwhile, the spray-washing device is lighter and more flexible compared with stainless steel materials in the prior art due to the PEEK material.
The side wall, close to the bottom, of the first accommodating groove 12 is annularly provided with a first step surface 16, the first step surface 16 enables the inner diameter D1, located at the front part of the first step surface 16, of the first accommodating groove 12 to be larger than the inner diameter D2, located at the rear part of the first step surface 16, the front end part of the first water inlet channel 13 protrudes outwards from the bottom of the first accommodating groove 12, and the front end surface of the first water inlet channel 13 is flush with the first step surface 16; when the gasket 6 and the second connector 2 are mounted at the bottom of the first accommodating groove 12, the gasket 6 is in contact with both the first step surface 16 and the front end surface of the first water inlet channel 13, so that the space of the first accommodating groove 12 behind the first step surface 16 forms a first independent cavity 17. This separates the incoming compressed air from the cleaning fluid.
The gasket 6 is provided with a first through hole 61 and a plurality of second through holes 62 arranged around the first through hole 61, the inner diameter of the first through hole is the same as the inner diameter of the first water inlet channel, the first through hole 61 is communicated with the first water inlet channel 13 in an aligned manner, and the plurality of second through holes 62 are communicated with the first independent cavity 17. In the present embodiment, the second through holes 62 may be five. The gasket 6 can be used for blocking direct contact between the first connector 1 and the second connector 2, has a sealing effect, and prevents gaps from being generated after the two connectors are subjected to natural thermal expansion and contraction, so that gas and liquid are leaked. The gasket 6 may be a silicone material. The gasket 6 completely separates the air inlet channel from the liquid inlet channel, and prevents the gas and the liquid from being mixed before reaching the conical mixing cavity 311, thereby affecting the atomization effect.
The center of the second joint 2 is provided with a second water inlet channel 21 and two second air inlet channels 22 symmetrically arranged around the second water inlet channel 21, the second water inlet channel 21 comprises a gradual change portion 211 and a transition portion 212 communicated with the gradual change portion 211, the inner diameter of the gradual change portion 211 gradually decreases from back to front, the maximum inner diameter d1 of the gradual change portion 211 is the same as the inner diameter of the first through hole 61, the minimum inner diameter d2 of the gradual change portion 211 is the same as the inner diameter of the transition portion 212, and the gradual change portion 211 is communicated with the first through hole 61. Since the inner diameter of the second liquid inlet passage 21 is made smaller by the large diameter, the flow rate of the liquid is enhanced. The compressed gas is extruded from the second independent cavity 23 into the tiny second air inlet channel 22 to form high-speed airflow, and when reaching the conical mixing cavity 311, the compressed gas collides with the cleaning liquid at a high speed so as to shear the cleaning liquid into mist particles.
The rear end face of the second connector 2 is provided with a concave area, the concave area is arranged on the periphery of the gradual change part 211 in a surrounding mode, when the gradual change part 211 is communicated with the first through hole 61 in an aligned mode, a second independent cavity 23 is formed between the gasket 6 and the concave area, the first independent cavity 17 is communicated with the second independent cavity 23 through the second through hole 61, and the second air inlet channel 22 is communicated with the second independent cavity 23. The relationship between the maximum inner diameter d1 of the taper portion 211 and the inner diameter d5 of the second intake passage 22 is 6:1. In this embodiment, the inner diameter d1 is 3mm and the inner diameter d5 is 0.5mm. The gas can enter the second independent cavity 23 from the first independent cavity 17 through the second through hole 61, and then reach the conical mixing cavity 311 through the second air inlet channel 22, because the inner diameter of the second air inlet channel 22 is small, the gas can form high-speed gas flow when passing through the second air inlet channel 22, and when reaching the conical mixing cavity 311, the gas flow can shear the liquid to form a gas-liquid mixture.
The front end of the second connector 2 is provided with a limiting part 24, the limiting part 24 surrounds the transition part 212, the inner diameter d3 of the limiting part 24 is larger than the outer diameter d4 of the transition part 212, the front end face of the limiting part 24 is flush with the front end face of the transition part 212, the second air inlet channel 22 is located between the limiting part 24 and the transition part 212, and the second air inlet channel 22 penetrates through the front end face and the rear end face of the second connector 2. Therefore, a sealed space is formed between the second connector 2 and the third connector 3, so that leakage of gas or liquid is prevented, and atomization effect is affected.
The third joint 3 includes a first base 31 and a second base 32, the first base 31 and the second base 32 are fixedly connected, and an outer diameter of the first base 31 is larger than an outer diameter of the second base 32 to form a third step surface 35; the first base 31 has a tapered mixing chamber 311 formed therein, the second base 32 has a compression passage 321 formed therein, the compression passage 321 communicates with a front end of the tapered mixing chamber 311, a rear end of the tapered mixing chamber 311 communicates with the transition portion 212, and a rear end of the tapered mixing chamber 311 communicates with the second intake passage 22.
