As shown in the figure, the water spray dust prevention device includes: a base plate 1, a water tank 2, a water pump 3, a nozzle 4, a dust prevention mechanism 5 and an angle adjustment mechanism 6. Among them, the water tank 2 and the angle adjustment mechanism 6 are both arranged on the base plate 1, the nozzle 4 is arranged on the angle adjustment mechanism 6, and the angle adjustment mechanism 6 is used to adjust the spray angle of the nozzle 4.

[0023] Preferably, a water filling port is opened at the top of the water tank 2, and a water filling pipe 10 is clamped at the water filling port. A funnel 11 is clamped at the end of the water filling pipe 10 placed outside the water tank 2, so that it is convenient to fill water into the water tank 2.

[0024] The dustproof mechanism 5 is arranged on the angle adjustment mechanism 6 , and is used to protect the injection port 41 of the nozzle 4 , to prevent dust from entering the injection port 41 , and to avoid clogging of the injection port 41 .

[0025] It can be seen that in the present embodiment, the nozzle 4 is arranged on the angle adjustment mechanism 6, and the spraying angle of the nozzle 4 is adjusted by the angle adjustment mechanism 6 to meet the water spraying requirements at different angles and improve the water spraying effect. The dustproof mechanism 5 protects the injection port 41 of the nozzle 4 and can prevent dust from clogging the injection port 41 of the nozzle 4, thereby ensuring the normal water spraying of the nozzle 4 and improving the water spraying effect, thus solving the problem in the prior art that the injection port of the nozzle in the dust reduction device is easily clogged and the injection angle is fixed.

[0026] See also Figures 1 to 3 In the above embodiment, the dust prevention mechanism 5 includes: two baffles 51 and two first drive mechanisms. The two first drive mechanisms are both arranged on the angle adjustment mechanism 6, and the two first drive mechanisms are respectively placed on both sides of the nozzle 4, specifically, the two first drive mechanisms are respectively placed on the left and right sides of the nozzle 4.

[0027] The two baffles 51 are arranged opposite to each other, and each baffle 51 is parallel to the injection port 41 of the nozzle 4, and each baffle 51 is placed in front of the injection port 41. The two baffles 51 correspond to the two first driving mechanisms one by one, and each baffle 51 is connected to the corresponding first driving mechanism, and each first driving mechanism is used to drive the corresponding baffle 51 to move so that the two baffles 51 are connected to each other. The two baffles 51 after docking correspond to the injection port 41 of the nozzle 4, and the two baffles 51 after docking cover the injection port 41 of the nozzle 4 to prevent dust from entering the injection port 41.

[0028] When the injection port 41 needs to be protected, the two first driving mechanisms drive the corresponding baffles 51 to move relative to each other, so that the two baffles 51 are connected to each other, and the two connected baffles 51 cover and block the injection port 41 of the nozzle 4. When water needs to be sprayed, the two first driving mechanisms drive the corresponding baffles 51 to move outward, so that the two baffles 51 are separated, so that the injection port 41 of the nozzle 4 is exposed, which is convenient for water spraying.

[0029] During specific implementation, the distance between the two baffles 51 and the injection port 41 may be pre-designed to ensure that the two baffles 51 after docking can cover the injection port 41 .

[0030] In specific implementation, each baffle 51 can be semicircular or rectangular, or other shapes, and this embodiment does not impose any restrictions on this. In this embodiment, the injection port 41 of the nozzle 4 is circular, each baffle 51 is semicircular, and the two baffles 51 after docking are circular as a whole, and the overall diameter of the two baffles 51 after docking is larger than the diameter of the injection port 41, so that the two baffles 51 after docking can fully cover the injection port 41.

[0031] Each first driving mechanism may include: a mounting plate 52, a driving frame 53 and a driving assembly 54. The mounting plate 52 is arranged on the angle adjustment mechanism 6, and the mounting plate 52 is parallel to the nozzle 4. Specifically, the plate surface of the mounting plate 52 is parallel to the length direction of the nozzle 4 ( Figure 1 That is, the plate surface of the mounting plate 52 is perpendicular to the plane where the injection port 41 is located, and the mounting plate 52 is placed on one side of the nozzle 4.

[0032] The driving assembly 54 is disposed on the mounting plate 52, and the driving assembly 54 is connected to the first side of the driving frame 53, and the second side of the driving frame 53 is connected to the corresponding baffle 51. The driving frame 53 is in a suspended state, and the driving assembly 54 is used to drive the driving frame 53 to move, so as to drive the baffle 51 to move. In this way, the two mounting plates 52 and the two driving frames 53 are respectively placed on the left and right sides of the nozzle 4, and the two driving assemblies 54 drive the corresponding driving frames 53 to move relative to each other, so as to drive the two baffles 51 to move relative to each other and then dock.

[0033] The driving assembly 54 includes: a driving rod 541, a gear 542 and a rack 543. The driving rod 541 is parallel to the mounting plate 52 and to the driving frame 53, that is, the driving rod 541 is parallel to the length direction of the nozzle 4, and the driving rod 541 is rotatably connected to the mounting plate 52. Specifically, the driving frame 53 and the driving rod 541 are respectively placed on both sides of the mounting plate 52, the driving frame 53 is close to the nozzle 4, and the driving rod 541 is placed on the side of the mounting plate 52 away from the nozzle 4. More specifically, a connecting plate 8 is vertically provided on one side of the mounting plate 52 away from the nozzle 4, the driving rod 541 is perpendicular to the connecting plate 8, and the connecting plate 8 is provided with a through hole, and the driving rod 541 is rotatably penetrated through the through hole so that the driving rod 541 can rotate relative to the connecting plate 8. Preferably, a bearing is provided in the through hole of the connecting plate 8, and the driving rod 541 is connected to the bearing.

[0034] The gear 542 is sleeved on the outside of the driving rod 541, and the gear 542 is fixed relative to the driving rod 541. The rack 543 is connected to the first side of the driving frame 53, and the rack 543 is meshed with the gear 542. The driving rod 541 is used to rotate under the action of an external force to drive the gear 542 to rotate, thereby driving the rack 543 to move, so that the driving frame 53 moves.

[0035] During specific implementation, a handle 9 is provided at one end of the driving rod 541 , and a staff member rotates the handle 9 to drive the driving rod 541 to rotate.

[0036] Preferably, there are two gears 542, which are spaced apart on the driving rod 541. There are two racks 543, which are spaced apart on the first side of the driving frame 53, and the positions of the two racks 543 correspond to the positions of the two gears 542 one by one, so that the two racks 543 mesh with the two gears 542 one by one.

[0037] For specific implementation, see Figure 2 When there are two gears 542 and two racks 543, the driving rod 541 and the driving frame 53 are respectively placed on both sides of the mounting plate 52, and the two gears 542 are respectively arranged at the two ends of the driving rod 541. Grooves are provided on the opposite sides of the mounting plate 52, and the two racks 543 correspond to the two grooves one by one. Each rack 543 can be movably inserted into the corresponding groove and meshed with the corresponding gear 542.

[0038] In order to limit the moving track of the driving frame 53, the driving assembly 54 further includes: at least one sliding rod 544. Each sliding rod 544 is arranged on the first side of the driving frame 53, and each sliding rod 544 can be movably penetrated in the mounting plate 52. Specifically, two sliding rods 544 are arranged at intervals on the driving frame 53, and the mounting plate 52 is provided with a penetration hole corresponding to each sliding rod 544, and the first end of each sliding rod 544 is connected to the first side of the driving frame 53, and each sliding rod 544 can be movably penetrated in the corresponding penetration hole, and the second end of each sliding rod 544 is placed on the side of the mounting plate 52 away from the nozzle 4. In this way, the movement of the driving frame 53 drives the sliding rod 544 to move, but the sliding rod 544 is movably connected to the mounting plate 52, so that the sliding rod 544 limits the moving track of the driving frame 53, ensuring the stable movement of the driving frame 53, and the sliding rod 544 supports the driving frame 53, so that the driving frame 53 remains in a suspended state, thereby improving the stability of the driving frame 53.

[0039] A limiting block 7 is provided at one end of each slide rod 544 away from the driving frame 53. Specifically, a limiting block 7 is provided at the second end of each slide rod 544. The cross-sectional size of the limiting block 7 is larger than the cross-sectional size of the slide rod 544. The limiting block 7 limits the slide rod 544 to prevent the slide rod 544 from detaching from the mounting plate 52.

[0040] In this embodiment, there are two sliding bars 544 , and the two sliding bars 544 are both disposed between the two racks 543 .

[0041] It can be seen that in the present embodiment, the staff rotates the driving rod 541, driving the gear 542 to rotate, and then driving the rack 543 to move, so that the driving frame 53 moves, thereby realizing the movement of the baffle 51. In this way, the two baffles 51 can be connected to each other, thereby covering and sealing the injection port 41, preventing the injection port 41 from being blocked by dust. The dustproof mechanism 5 has a simple structure and is easy to implement.

[0042] See also Figure 1 , Figure 3 and Figure 4 In the above embodiments, the angle adjustment mechanism 6 includes: a support frame 61, a rotating plate 62 and a second driving mechanism 63. The bottom end of the support frame 61 is vertically arranged on the bottom plate 1, and the top end of the support frame 61 is rotatably connected to the first end of the rotating plate 62. Preferably, the top end of the support frame 61 is hingedly connected to the first end of the rotating plate 62. Specifically, the support frame 61 includes: two support bodies arranged in parallel, the bottom of each support body is vertically arranged on the bottom plate 1, and the first end of the rotating plate 62 is hingedly connected to the tops of the two support bodies.

[0043] The spray head 4 and the dustproof mechanism 5 are both disposed on the rotating plate 62. Specifically, the two mounting plates 52 in the dustproof mechanism 5 are both vertically disposed on the rotating plate 62. The spray head 4 is fixedly connected to the rotating plate 62.

[0044] The second driving mechanism 63 is disposed between the bottom plate 1 and the second end of the rotating plate 62 , and is used to drive the second end of the rotating plate 62 to rotate around the first end to adjust the angle of the rotating plate 62 , thereby adjusting the spraying angle of the nozzle 4 .

[0045] The second driving mechanism 63 includes: a threaded barrel 631 and a threaded rod 632. The first end of the threaded barrel 631 is rotatably connected to the second end of the rotating plate 62, the first end of the threaded rod 632 is rotatably connected to the bottom plate 1, and the second end of the threaded barrel 631 is screwed to the second end of the threaded rod 632. By rotating the threaded rod 632, the threaded rod 632 is screwed into or out of the threaded barrel 631 to adjust the overall height of the threaded rod 632 and the threaded barrel 631, and then adjust the inclination of the rotating plate 62, that is, adjust the angle of the rotating plate 62, and then adjust the spray angle of the nozzle 4.

[0046] Preferably, the second driving mechanism 63 further includes: a driving block 633, a first connecting body 634 and a second connecting body 635. The first connecting body 634 is U-shaped, the closed end of the first connecting body 634 is connected to the second end of the rotating plate 62, the open end of the first connecting body 634 faces the bottom plate 1, and the first end of the threaded barrel 631 is hinged in the first connecting body 634. Specifically, the first end of the threaded barrel 631 is inserted into the first connecting body 634 from the open end of the first connecting body 634, and the first end of the threaded barrel 631 is hingedly connected to two opposite side walls of the first connecting body 634.

[0047] The second connecting body 635 is also U-shaped, the closed end of the second connecting body 635 is connected to the bottom plate 1, and the open end of the second connecting body 635 faces the rotating plate 62, that is, the open end of the second connecting body 635 is arranged opposite to the open end of the first connecting body 634. The driving block 633 is hinged in the second connecting body 635, and the first end of the threaded rod 632 is rotatably connected to the driving block 633. Specifically, the driving block 633 is placed in the second connecting body 635 from the open end of the second connecting body 635, and the bottom end of the driving block 633 is hingedly connected to the two opposite side walls of the second connecting body 635. The top end of the driving block 633 is connected to the first end of the threaded rod 632 through a bearing so that the threaded rod 632 can rotate freely. More specifically, the top end of the driving block 633 is provided with a bearing, and the first end of the threaded rod 632 is connected to the bearing.

[0048] It can be seen that in the present embodiment, by rotating the threaded rod 632, the threaded rod 632 is screwed out of the threaded barrel 631, so that the overall height of the threaded rod 632 and the threaded barrel 631 is increased. Since the threaded barrel 631 is hingedly connected to the first connecting body 634, and the driving block 633 is hingedly connected to the second connecting body 635, the overall height of the threaded rod 632 and the threaded barrel 631 is increased, so that the second end of the rotating plate 62 is raised, that is, the second end of the rotating plate 62 can be rotated around the first end, so that the inclination angle of the rotating plate 62 can be adjusted, that is, the spraying angle of the nozzle 4 is adjusted. The angle adjustment mechanism 6 has a simple structure and is easy to implement.

[0049] See also Figures 1 to 4 The use process of the water spray dust prevention device is introduced as follows: the threaded rod 632 is rotated to unscrew the threaded rod 632 from the inside of the threaded barrel 631, which drives the second end of the rotating plate 62 to rotate, so that the angle of the rotating plate 62 can be adjusted, that is, the spray angle of the spray head 4 is adjusted. Then, the water pump 3 is started to pump out the water inside the water tank 2, and the water pump 3 delivers the water to the spray head 4, and the spray port 41 of the spray head 4 sprays the water. After use, the handle 9 is rotated, and the handle 9 drives the driving rod 541 to rotate, and then drives the gear 542 to rotate, thereby driving the rack 543 to move, that is, the driving frame 53 can move inward, and each slide rod 544 moves with the driving frame 53, and each slide rod 544 limits the movement trajectory of the driving frame 53. The relative inward movement of the two driving frames 53 drives the two baffles 51 to move relative to each other and then connect with each other. The baffles 51 after docking cover and block the spray port 41 to prevent the spray port 41 from being blocked. When water spraying is needed again, the handle 9 is rotated in the opposite direction, and the handle 9 drives the driving rod 541 to move, and then drives the driving frame 53 to move outward through the gear 542 and the rack 543. The relative outward movement of the two driving frames 53 drives the two baffles 51 to separate, so that the injection port 41 is exposed, and then the water pump 3 is started, and the injection port 41 sprays water.

[0050] In summary, in the present embodiment, the nozzle 4 is arranged on the angle adjustment mechanism 6, and the spraying angle of the nozzle 4 is adjusted by the angle adjustment mechanism 6 to meet the water spraying requirements at different angles and improve the water spraying effect. The dustproof mechanism 5 protects the injection port 41 of the nozzle 4 and can prevent dust from clogging the injection port 41 of the nozzle 4, thereby ensuring the normal water spraying of the nozzle 4 and improving the water spraying effect, thus solving the problem that the injection port of the nozzle in the dust reduction device in the prior art is easily clogged and the injection angle is fixed.
