[0026] As Figure 1 and Figure 2The atomizing nozzle mainly comprises a matched feed assembly 1 and a cover assembly 2, the cover assembly 2 is usually mounted on the feed assembly 1; alternatively, the cover assembly 2 is usually preferably detachably mounted on the feed assembly 1; the detachable mode can adopt the existing conventional mode, such as setting external threads on at least a partial circumferential surface of the feed assembly 1 and setting internal threads matched with the external threads on an inner wall of the cover assembly 2, so as to realize the detachability through the threaded connection mode. When the feed assembly 1 is a non-regular cylindrical structure (such as at least one step portion a is formed on the circumferential surface), the inner wall of the cover assembly 2 is also formed with a corresponding structure, at this time, at least one sealing ring or a conventional sealing structure can be arranged between them to realize the sealing between the feed assembly 1 and the cover assembly 2. Through the cooperation of the specific structure of the feed assembly 1 and the cover assembly 2, the assembly parts can be tightly combined together, the processing technology is simplified, the machining is facilitated, the machining cost is reduced, the total number of parts is reduced, the overall cost is reduced, the structure is compact, the functions are complete, the durability is reliable, the technology is simple, and the manufacturing cost is low; and the atomized particle size is reduced to reduce the gas consumption during use.

[0027] The feed assembly 1 comprises a nozzle body 11, a discharge pressurizing head 13 (formed in a mode of one-piece forming, the same below) formed at one end of the nozzle body 11, a medium inlet flow channel 14 penetrating through the nozzle body 11 and extending into the discharge pressurizing head 13, and an auxiliary gas flow channel 15 opened in the nozzle body 11. The nozzle body 11 and the discharge pressurizing head 13 preferably have the same axial line, the medium inlet flow channel 14 is used for inputting the medium to be atomized, and the auxiliary gas flow channel 15 is used for inputting the auxiliary gas. In the embodiment, the medium inlet flow channel 14 preferably has the same axial line with the nozzle body 11 or the discharge pressurizing head 13; the auxiliary gas flow channel 15 is obliquely arranged, and the distance between the auxiliary gas flow channel 15 and the axial line of the nozzle body 11 gradually decreases in the direction from the nozzle body 11 to the discharge pressurizing head 13. The discharge pressurizing head 13 is provided with at least one discharge hole 132 communicated with the medium inlet flow channel 14, the number of the discharge holes 132 is preferably 2-8, and the discharge holes 132 are equidistantly or symmetrically arranged on the circumferential surface of the discharge pressurizing head 13; in the embodiment, the discharge holes 132 are four, and the included angle between adjacent two discharge holes 132 is 90°, so as to ensure the uniformity of the medium discharge. The feed assembly 1 usually further comprises a connecting head 12 formed at the other end of the nozzle body 11, so that the discharge pressurizing head 13 and the connecting head 12 are respectively located at the two sides of the nozzle body 11, at this time, the medium inlet flow channel 14 also penetrates through the connecting head 12. The circumferential surface of the nozzle body 11 is preferably provided with a limiting stop ring body 111 arranged in a spaced mode with the cover assembly 2, which can be matched with the connecting head 12 to facilitate the installation of the atomizing nozzle.

[0028] The medium inlet flow channel 14 includes a first channel 141 formed in the spray head body 11, a second channel 143 formed in the spray head body 11 and extending into the outlet pressurizing head 13, and an adapter channel 142 connecting the first channel 141 and the second channel 143. The cross-sectional area of the first channel 141 is greater than that of the second channel 143, so that the medium can be pressurized and throttled. The ratio of the diameter of the first channel 141 to that of the second channel 143 is preferably 3-6, and the medium after pressurization increases the ejection speed at the outlet orifice 132.

[0029] The cover assembly 2 includes a cover body 21 sleeved on the spray head body 11 (when the cover assembly 2 is detachably mounted on the inlet assembly 1, it is achieved by detachably mounting the cover body 21 on the spray head body 11), a flared mouth 23 formed on the end face of the cover body 21 and matched with the outlet pressurizing head 13 (the diameter of the flared mouth 23 gradually increases in the direction away from the spray head body 11), and a gas speed-up flow channel 24 formed between the cover body 21 and the outlet pressurizing head 13 to communicate the flared mouth 23 and the auxiliary gas flow channel 15, so that the pressure of the auxiliary gas can be greatly increased, thereby achieving the atomization effect of the medium. In this embodiment, the cover assembly 2 further includes a gas storage space 22 surrounded by the spray head body 11, the outlet pressurizing head 13, and the cover body 21 (i.e., the gas storage space 22 is surrounded by the spray head body 11, the outlet pressurizing head 13, and the cover body 21), so that the gas storage space 22 is in communication with the auxiliary gas flow channel 15 and the gas speed-up flow channel 24, respectively. This can effectively increase the gas pressure and further improve the atomization effect of the medium, so as to achieve the required particle size of the atomized medium. The gas speed-up flow channel 24 includes a straight-through flow channel portion 242 and a flared portion 241 connected between the cover body 21 and the outlet pressurizing head 13. The straight-through flow channel portion 242 is in communication with the flared mouth 23, and the flared portion 241 is in communication with the gas storage space 22, so that the auxiliary gas is introduced from the gas storage space 22 into the flared mouth 23 to fully mix with the medium outlet at the outlet orifice 132, thereby improving the atomization effect.

[0030] The general principle of the atomizing nozzle is as follows: the high-speed medium hits the thick wall of the flared mouth 23, accelerating the crushing of the medium, and the high-pressure gas from the gas speed-up flow channel 24 further disperses, further dispersing the atomized particle size, thereby forming smaller particle size and increasing the atomization effect.

[0031] In the embodiment, the specific structure of the discharge pressurizing head 13 comprises a pressurizing body 130 and a discharge head 131 formed on the outer end surface of the pressurizing body 130 (i.e. the end surface facing away from the nozzle body 11), and the gas speed-up flow channel 24 is located at the outer periphery of the pressurizing body 130. In the embodiment, the inner end surface of the pressurizing body 130 is formed on the nozzle body 11, and a first inclined surface 135 with a gradually decreasing diameter from inside to outside is formed at the connection between the pressurizing body 130 and the nozzle body 11, and the first inclined surface 135 is located in the gas storage space 22, so that the turbulence of the auxiliary gas in the gas storage space 22 can be reduced. In the embodiment, the discharge hole 132 is formed on the peripheral surface of the discharge head 131 and is connected with the second passage 143, so that the medium is pressurized and atomized. The pressurizing body 130 and the discharge head 131 have a medium-impact-preventing bending area 133 and a smooth transition connecting area 134 (in this case, the edge of the pressurizing body 130 at the connection with the discharge head 131 is a gap structure with a gap of 0.1-0.2 mm (i.e. the medium-impact-preventing bending area 133), and the edge of the outer end surface of the pressurizing body 130 is an outer arc structure with a radius of 0.5-1.5 mm), which functions to shape the high-pressure gas and avoid direct blowing on the discharge hole 131 and affecting the medium crushing of the horn 23; the discharge head 131 has a second inclined surface located outside the discharge hole 132 and gradually decreasing in diameter from inside to outside, so that the above-mentioned structure and the horn 23 cooperate to form an atomization angle limiting space, so as to limit the ejection angle of the mixed medium and air after crushing, so as to achieve the ideal atomization angle and reduce the penetration distance.

[0032] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
