Description

Technical Field

[0001] The utility model belongs to the technical field of atomizing nozzles, and in particular relates to a centrifugal atomizing nozzle. Background Art

[0002] The atomizing nozzle is a type of farmland sprinkler irrigation equipment that sprays pressurized water into the air through the nozzle and scatters it in the form of mist in the fields and crops. It is suitable for flower fields, lawns, green spaces, factories, greenhouses, and agricultural water-saving irrigation. The working principle of the nozzle is to pump water into a centrifugal atomizing turntable, and the liquid is atomized and decomposed into droplets through the high-speed rotation of the centrifugal pump. However, when the nozzle is in use, the head is exposed and lacks protection. Therefore, when used outdoors, it is easy to be damaged by bumps or falls, resulting in leakage during subsequent spraying, affecting the spray distance. Therefore, the inventor proposed a centrifugal atomizing nozzle. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] This specific embodiment is a centrifugal atomizing nozzle, and its structural schematic diagram is as follows Figure 1 , Figure 2 As shown, it includes a nozzle body 1 and a protective cover 5. The protective cover 5 is installed at the water outlet above the nozzle body 1. The protective cover 5 is a cylindrical structure, and two sets of sealing plates 4 are rotatably installed on the upper surface. Both sets of sealing plates 4 are semi-disc structures.

[0024] Reference Figure 2 , Figure 3 , Figure 4 , connecting blocks 6 are symmetrically protruded on the outer walls of both sides of the protective cover 5, a fixing ring 3 is provided on the outer fixed sleeve of the nozzle body 1, a fixing column 2 is fixedly installed on the upper surface of the fixing ring 3, the center of the connecting block 6 is hollow, the fixing column 2 passes through the connecting block 6, a gear 10 is rotatably installed inside the connecting block 6, a second tooth groove 13 is vertically opened on the outer wall of the fixing column 2, the gear 10 is adapted to the second tooth groove 13, and two groups of sealing plates 4 are respectively provided with sliding grooves on the surfaces facing the nozzle body 1, a slider 7 is slidably installed in the sliding groove, and a lifting rod 9 is rotatably connected to the side of the slider 7 away from the sliding groove. The lifting rod 9 moves in the opposite form to the fixed column 2. During the movement of the lifting rod 9, the other end applies pressure to the slider 7. Since the slider 7 is rotatably connected to the lifting block and slidably connected to the sliding groove, the lifting rod 9 can apply pressure to the sealing plate 4, so that the sealing plate 4 is forced to unfold.

[0025] Reference Figure 3 , Figure 4, the lifting rod 9 is vertically arranged inside the protective cover 5, and the outer sleeve of the lifting rod 9 is provided with a fixed block 15, through which the lifting rod 9 slides, and the fixed block 15 is fixed on the inner wall of the protective cover 5. A first tooth groove 11 is provided on the outer wall of the lower end of the lifting rod 9, and the first tooth groove 11 is adapted to the gear 10. The lifting rod 9 and the fixed column 2 are respectively arranged on both sides of the gear 10. A buckle 12 is embedded and installed on the outer wall of the fixed column 2, and the outer wall of the connecting block 6 has an installation cavity for the buckle 12 to slide into. One end of the buckle 12 that slides into the installation cavity is fixedly connected to a reset spring 14, and the other end of the reset spring 14 is fixedly connected to the inner wall of the installation cavity. There is a card slot on the outer wall of the connecting block 6, and the buckle 12 is adapted to be snapped in. When the buckle 12 is separated from the card slot, the protective cover 5 can be slid so that it gradually moves away along the nozzle body 1, and the connecting block 6 on the outer wall of the protective cover 5 also moves accordingly.

[0026] Working principle: When in use, connect the nozzle body 1 to the water pipe. When spraying is required, the protective cover 5 can be started to make the water outlet of the nozzle body 1 open. Press the buckle 12 to withdraw it from the slot and retract it into the installation cavity. The reset spring 14 is compressed. When the buckle 12 is separated from the slot, the protective cover 5 can be slid to gradually move away from the nozzle body 1, and the connecting block 6 on the outer wall of the protective cover 5 also moves accordingly. When the connecting block 6 moves to be flush with another buckle 12 on the outer wall of the fixed column 2, the reset spring 14 pops out and is connected to the slot on the connecting block 6, so that the protective cover 5 is moved and fixed. During the movement of the protective cover 5, the gear 10 installed on the inner side of the connecting block 6 and the protective cover 5 rotates along the second rotation of the outer wall of the fixed column 2. After the gear 10 rotates, the lifting rod 9 inside the protective cover 5 is provided with a first gear 10 on the outer wall that matches the gear 10. When the lifting rod 9 moves in the opposite direction along with the movement of the connecting block 6, the lifting rod 9 and the fixed column 2 move in the opposite direction. During the movement of the lifting rod 9, the other end applies pressure to the slider 7. Since the slider 7 is rotatably connected to the lifting block and slidably connected to the slide groove, the lifting rod 9 can apply pressure to the sealing plate 4, so that the sealing plate 4 is forced to unfold. Since the above-mentioned buckle 12 is clamped and fixed with the connecting block 6, the sealing plate 4 is fixed after opening again. At this time, the nozzle main body 1 can spray water mist, and after use, the protective cover 5 is put away. When the connecting block 6 moves in the opposite direction along the fixed column 2, the above-mentioned structures all move in the opposite direction, so that the lifting rod 9 tightens and fixes the sealing plate 4 until the connecting block 6 is clamped with the buckle 12 located below again, and the sealing plate 4 is fixed. Through the setting of the protective cover 5 and the sealing plate 4, the water outlet position of the nozzle can be protected to avoid the impact of collision and falling when used outdoors.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
