[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific implementation manners and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0033] Referring to the attached Figures 1 to 8, A leak-proof turbocharged two-fluid centrifugal atomization pesticide spraying machine in an embodiment of the present utility model includes a main body 10 and a telescopic assembly 20 provided on the main body 10. The telescopic assembly 20 includes a sleeve 21, a water outlet pipe 22 installed in the sleeve 21, a water outlet nozzle 23 located at the front end of the water outlet pipe 22, and a flaring nozzle 24 installed on the water outlet nozzle 23;

[0034] The flaring nozzle 24 is rotatably installed on the outer periphery of the water outlet nozzle 23, and there is an air outlet gap 241 between the flaring nozzle 24 and the sleeve 21. The flaring nozzle 24 is provided with fan blades 242 corresponding to the air outlet gap 241, and the inner side wall of the flaring nozzle 24 is provided with crushing teeth 243 corresponding to the water outlet nozzle 23;

[0035] A blower 30 for driving the rotation of the flaring nozzle 24 is arranged in the main body 10, and the blower 30 is connected to a main control board 40 (PCBA board); a water supply pipe 11 connected to the water outlet pipe 22 is arranged in the main body 10; during use, water flows from the water supply pipe 11 to the water outlet nozzle 23 and sprays out, and the water contacts the crushing teeth 243 of the rotating flaring nozzle 24 and is cut into water vapor, and the blower 30 blows air from the air outlet gap 241, and then blows the water vapor forward.

[0036] The water outlet nozzle 23 includes an inlet port 231 and a plurality of outlet ports 232, and a crushing part is arranged at the communication part between the inlet port 231 and the outlet ports 232 (in this embodiment, the crushing part is a crushing groove 233. When water enters from the inlet port 231, the water flow directly impacts the crushing groove 233 and cracks and sprays out from the plurality of outlet ports 232).

[0037] Preferably, a bearing 25 is arranged between the flaring nozzle 24 and the water outlet nozzle 23, so that the rotation of the flaring nozzle 24 and the fan blades 242 installed on the flaring nozzle 24 is smoother.

[0038] Furthermore, the sleeve 21 is installed in the main body 10 in a front-back telescopic manner. A water stop cover 211 is arranged at the rear end of the water outlet pipe 22, and the water supply pipe 11 has a water supply hole 111; a water inlet hole 221 is arranged on the circumferential side wall of the water outlet pipe 22; when the sleeve 21 moves forward, an inlet gap is formed between the water outlet pipe 22 and the water supply pipe 11, and when the sleeve 21 moves backward, the water stop cover 211 blocks the water supply hole 111. Usually, the water stop cover 211 is made of silica gel.

[0039] Specifically, the main body 10 includes a main housing 101 and a nozzle 102. The nozzle 102 is threadedly connected to the front end of the main housing 101. An installation gap is maintained between the nozzle 102 and the sleeve 21, and a spring 103 for pushing the sleeve 21 to reset backward is installed in the installation gap.

[0040] As Figure 7 shown, during operation, the blower 30 is started, causing the telescopic assembly 20 to move forward (thus opening a water inlet gap between the water outlet pipe 22 and the water supply pipe 11) and causing the bell mouth 24 to rotate; the water supply pipe 11 is connected to an external water source, and water enters the water outlet pipe 22 through the water inlet hole 221 of the water outlet pipe 22 and flows into the water outlet nozzle 23. After the water outlet nozzle 23 breaks the water flow, it sprays out from a plurality of water outlet ports 232 (this is the first fragmentation and atomization).

[0041] After the water flow sprays out from the water outlet ports 232 of the water outlet nozzle 23, it contacts the fragmentation teeth 243 of the bell mouth 24 and is cut by the fragmentation teeth 243 of the bell mouth 24 (this is the second fragmentation and atomization); it should be noted that when the water flow sprays out from the water outlet nozzle 23, due to the relatively large air flow in the air outlet gap 241, the water flow will move towards the air outlet gap 241 direction (performing a centrifugal motion away from the center of the bell head), so that the water flow and the fragmentation teeth 243 are in full contact, improving the fragmentation effect.

[0042] Finally, the water vapor fragmented and atomized by the fragmentation teeth 243 is blown further away and has a longer moving distance under the action of the air flow in the air outlet gap 241.

[0043] The main body 10 is preferably provided with a handle 104 for the convenience of users; preferably, the handle 104 is a hollow structure with a cavity inside, and the water path of the water supply pipe 11 passes through the cavity to connect to the water outlet pipe 22; specifically, the water supply pipe 11 also has a water inlet end, and its water inlet end is preferably provided on the rear end face of the main body 10 (main housing 101); the handle 104 is preferably provided on the upper side of the main body 10 (main housing 101).

[0044] The design focus of the present utility model is that mainly through the specific settings of the atomizing pesticide spraying machine, by repeatedly fragmenting the water body, the atomization effect of the water body is improved; at the same time, through the setting of the air blowing gap and the blower, the spraying distance of the water vapor is made farther; secondly, by setting a water stop valve, the problem of water body backflow can be ingeniously and low-costly solved.

[0045] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
