Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the embodiment of the present invention provides an aerosol nozzle, which includes a cylindrical nozzle body 11 and a liquid inlet pipe 17 connected thereto; a spray nozzle 103, an atomizing channel 14, a gas nozzle 102 and a gas inlet channel 13 which are coaxial with the nozzle body 11 are sequentially arranged in the nozzle body from left to right; the left side of the spray opening 103 penetrates through the left end face of the nozzle body 11, and the right side of the air inlet channel 13 penetrates through the right end face of the nozzle body 11; the atomizing nozzle 103 is communicated with the atomizing channel 14, the atomizing channel 14 is communicated with the gas nozzle 102, and the gas nozzle 102 is communicated with the gas inlet channel 13; a liquid spraying port 105 communicated with the atomization channel 14 is arranged at the side of the atomization channel; the axis of the liquid spray opening 105 is perpendicular to the axis of the nozzle body 11; a liquid inlet channel 12 coaxial with the liquid inlet pipe 17 is arranged in the liquid inlet pipe; the liquid spraying port 105 and the liquid inlet channel 12 are coaxial and are communicated with each other; the bore of the nebulization channel 14 is greater than the bore of the air jet 102.
In the present invention, in order to simplify the structure, the atomizing nozzle 103, the atomizing passage 14, the air nozzle 102 and the air inlet passage 103 are collectively arranged in the head body in a front-rear arrangement, thereby minimizing the volume of the atomizing nozzle. In order to achieve a good spraying effect, the inner diameter of the atomizing channel 14 is set to be larger than the inner diameter of the gas nozzle 102, the gas nozzle 102 has a smaller diameter, a throttle is formed, when a gas flow with pressure enters from the gas inlet channel 13 and is conveyed to the gas nozzle 102, the gas is forced to increase the flow speed, then the gas flowing out of the gas nozzle 102 at a high speed enters the atomizing channel 14 with the suddenly increased volume, a negative pressure area is formed in a cavity of the atomizing channel 14, liquid is automatically sucked from the liquid inlet channel 12, the liquid enters the atomizing channel 14 through the liquid nozzle 105 and is mixed with the gas, and spraying is formed after the gas and the liquid are mixed.
Further, the caliber of the air nozzle 102 is 0.5 mm-0.6 mm.
Multiple tests prove that the inner diameter of the air nozzle 102 can achieve better effect within the range.
Further, the spray opening 103 is tapered, and one end of the spray opening connected with the atomizing channel 14 is a tapered small end.
The conical spray opening 103 facilitates uniform dispersion of the aerosol generated and is therefore provided in the form of a bell mouth.
Further, the right end of the nozzle body 11 is provided with an internal thread.
The aerosol nozzle of the present application can be threadably connected to the aerosol generator body structure to ensure its convenient disassembly and cleaning.
Further, the aerosol nozzle is further provided with a conical air inlet 101 coaxial with the nozzle body 11, and the large end of the conical surface of the conical air inlet 101 is located on the right end face of the nozzle body 11.
The tapered inlet port facilitates gas flow and therefore the tapered inlet port 101 is provided at the point of attachment to the aerosol generator body structure, i.e. at the rightmost end of the nozzle body 11.
Further, the air intake passage 13 includes a right circular hole portion and a left conical hole portion, and a small end of the conical hole portion is connected to a right side of the air ejection port 102; the aperture of the circular hole portion is larger than the aperture of the atomization passage 14.
Because the caliber of the gas nozzle 102 is far smaller than that of the gas inlet channel 13, in order to enable the gas to flow smoothly and reduce the flow resistance as much as possible, the side of the gas inlet channel 13 close to the gas nozzle 102 can be transited smoothly by a conical surface.
Further, the nozzle body 11 and the liquid inlet pipe 17 are connected by screw threads.
To ensure easy disassembly, matching threads are also provided on the nozzle body 11 and the inlet pipe 17, which are threadedly connected.
The assembled aerosol atomizing nozzle is shown in figure 2.
