[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 9 As shown, the divergent high-pressure fog cannon includes a support base 1 and a fog cannon barrel 2 installed on the support base 1, and a mounting plate 3 is fixedly arranged inside the fog cannon barrel 2. Specifically, strip holes 21 are symmetrically opened on the inner wall of the fog cannon barrel 2, and both ends of the mounting plate 3 are inserted into the strip holes 21 for fixation, and a high-pressure rotator 4 is installed in the middle of the mounting plate 3.

[0027] The high-pressure rotator 4 includes a shell 5, a water delivery component 6 disposed inside the shell 5, and a water outlet component 7 disposed at the lower part of the shell 5. The shell 5 is an integrated structure, and a water inlet 51 for connecting a high-pressure water pipe is disposed at the top of the shell 5. A receiving cavity 52 matching the water delivery component 6 is provided in the shell 5. The lower end of the water delivery component 6 is connected to the water outlet component 7, and drives the water outlet component 7 to rotate.

[0028] The water delivery component 6 includes a compression spring 61, a water inlet valve 62, a friction component 63, a central rotating shaft 64, a bearing group 65 and a fixed bottom bracket 66 from top to bottom. The water inlet valve 62, the friction component 63 and the central rotating shaft 64 are all hollow structures, which are connected in sequence from top to bottom to form a water channel, so that the incoming water flow passes through the water delivery component 6 to reach the water outlet component 7; the lower end of the compression spring 61 abuts against the water inlet valve 62, and the setting of the compression spring 61 makes the water inlet valve 62 keep close to the central rotating shaft 64. The outer edge of the lower end of the water inlet valve 62 is provided with a circumferential protrusion 621 for maintaining circumferential fixation with the shell 5, and the circumferential protrusion 621 is engaged with the limiting groove 53 of the inner cavity 52 of the shell 5; the bottom of the water inlet valve 62 abuts against the friction component 63, and the friction component 63 is specifically a first friction component stacked up and down. Ring 631 and the second friction ring 632, the bottom of the second friction ring 632 is in contact with the central shaft 64, the function of the first friction ring 631 and the second friction ring 632 is to drive the central shaft 64 to rotate under the action of water pressure; the bearing group 65 is sleeved on the central shaft 64, the bearing group 65 includes a first deep groove ball bearing 651, a thrust ball bearing 652 and a second deep groove ball bearing 653 from top to bottom, the inner wall part of the bearing group 65 can rotate with the rotation of the central shaft 64, the two deep groove ball bearings mainly bear radial force, and the axial force on the shaft needs to be borne by the thrust ball bearing 652, otherwise it will cause the deep groove ball bearing to work in an angular contact state and fail due to excessive axial force, so the combined design of the thrust ball bearing 652 and the deep groove ball bearing can better ensure the force performance.

[0029] The fixed bottom bracket 66 is fixedly mounted on the mounting plate 3 by screws. The water outlet assembly 7 includes a stepped sleeve 71, a pivot joint 72, a water outlet rotating rod 73 and a nozzle 74. The stepped sleeve 71 is fixedly sleeved on the lower end of the central rotating shaft 64, the pivot joint 72 is fixedly mounted on the lower end of the stepped sleeve 71, and the side wall of the pivot joint 72 is evenly provided with three mounting holes 721. A water outlet rotating rod 73 is fixedly arranged in each mounting hole 721. The end of the water outlet rotating rod 73 away from the mounting hole 721 is fixedly provided with a nozzle 74. The bent portion 731 of the water outlet rotating rod 73 away from the mounting hole 721 is bent in the counterclockwise direction with the central rotating shaft 64 as the center, so that when the high-pressure water is sprayed from the nozzle 74, the water flow provides a force in the same side direction of the water outlet rotating rod 73, so that the three water outlet rotating rods 73 can rotate at high speed in the clockwise direction under the thrust of the high-pressure water.

[0030] Preferably, a first groove 622 is opened on the outer wall of the water inlet valve 62, a retaining ring 623 and an O-ring 624 are sleeved on the first groove 622, an O-ring 624 is sleeved on the top of the central shaft 64, the shell 5 and the fixed base 66 are fixedly connected by threads, and an O-ring 624 is sleeved on the bottom of the external thread of the fixed base 66. The retaining ring 623 and O-ring 624 enhance the sealing performance of the high-pressure rotator 4.

[0031] Preferably, the water delivery components 6 are all subjected to special oxidation treatment, and can withstand immersion in disinfectant without corrosion. The water outlet rotating rod 73 and the nozzle 74 are both made of corrosion-resistant stainless steel, which can meet the requirements of disinfection spray. In addition, the first friction ring 631 and the second friction ring 632 are made of a special alloy with high hardness, the first friction ring 631 is solid-state welded to the water inlet valve 62, and the second friction ring 632 is solid-state welded to the central rotating shaft 64.

[0032] An angle adjustment mechanism 8 is provided on both sides of the fog cannon barrel 2 for adjusting the spray angle of the fog cannon barrel 2. The angle adjustment mechanism 8 includes a limit plate 81 and a spring mechanism 82. The limit plate 81 is fixedly installed on both sides of the fog cannon barrel 2. A plurality of limit holes 811 with different heights are provided on the limit plate 81. In this embodiment, there are four limit holes 811, which can control the fog cannon barrel 2 in the range of 0°-60°. The spring mechanism 82 includes a fixed column 821, a shaft core 822, a spring 823 and a locking ring 824. The fixed column 821 is fixed at On the support seat 1, the shaft core 822 is arranged in the fixed column 821, and the spring 823 is wound on the shaft core 822. A through hole 8221 is opened at the end of the shaft core 822 away from the fog cannon barrel 2, and a locking ring 824 passes through the through hole 8221. The locking ring 824 is convenient for lifting and locking the position. When in use, pull out the locking ring 824, adjust the angle of the fog cannon barrel 2, loosen the locking ring 824, and insert the shaft core 822 into the corresponding limit hole 811 under the elastic force of the spring 823 to complete the angle adjustment of the fog cannon barrel 2, and the operation is very convenient.

[0033] In addition, protective nets 22 are installed at both ends of the fog cannon barrel 2 to improve the safety of use. A handle is provided on the top of the fog cannon barrel 2 for easy transportation.

[0034] In addition, the divergent high-pressure fog cannon of the present invention can also be mounted on a tricycle (not shown in the figure) to make a high-pressure fog cannon vehicle, thereby enriching the use scenarios of the product.

[0035] The working process of the double-bearing high-pressure rotator of the present invention is: the high-pressure water pipe is connected to the water inlet, and the high pressure input from the water inlet passes through the compression spring, the water inlet valve, the first friction ring, the second friction ring, the central rotating shaft, the stepped shaft sleeve, the pivot joint, and the water outlet rotating rod in sequence, and is finally sprayed out by three nozzles. Due to the angle setting of the lower end of the water outlet rotating rod, the thrust of the high-pressure water will drive the water outlet rotating rod to rotate at a high speed, so that the nozzle sprays water mist in a rotating state, and the high-speed rotating water outlet rotating rod will generate wind force inside the mist outlet barrel while rotating, thereby enhancing the spraying effect. The spraying efficiency is high, and large-scale dust removal and disinfection such as residential areas and communities can be carried out.
