Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, specifically to a nozzle assembly structure. Background Technology

[0002] Nozzles are mostly installed in various spraying, misting, oil spraying, sandblasting, and coating equipment, playing different roles. They are widely used in environmental protection, pre-coating treatment, circuit boards, petroleum, chemical, steel, metallurgy, electronics, cement, food, papermaking, printing, agriculture and animal husbandry and other industries. They can be said to be ubiquitous.

[0003] In the process of achieving the above, the inventors discovered at least the following problems with the technology: When the nozzle is in use, a filter screen is usually required at the nozzle inlet to filter the incoming water, and some existing filter screens are inconvenient to clean quickly when cleaning is required. Therefore, we propose a nozzle assembly structure. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a nozzle assembly structure that solves the problem that some existing filters are inconvenient to clean quickly when cleaning is required.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a nozzle assembly structure, including a nozzle body, a limiting block fixedly installed on the inner wall of the nozzle body, a filter cylinder provided inside the nozzle body on one side of the limiting block, an elastic metal strip fixedly installed on the inner wall of the filter cylinder, and metal filter screens fixedly installed on both sides of the elastic metal strip inside the filter cylinder.

[0008] A bracket is fixedly installed on the inner side of the elastic metal strip, a first spring is fixedly installed on the inner top wall of the bracket, a movable block is fixedly installed on one end of the first spring, a striking rod is fixedly inserted inside the movable block, and one end of the striking rod contacts the elastic metal strip.

[0009] Preferably, an atomizing spray plate is fixedly installed at the water outlet end of the nozzle body.

[0010] Preferably, one end of the striking rod extends through the outside of the bracket and is fixedly connected to a pull ring.

[0011] Preferably, a second spring is fixedly installed inside the filter cartridge, and a semi-circular locking block is fixedly installed at one end of the second spring. A semi-circular locking groove adapted to the semi-circular locking block is opened on the inner wall of the nozzle body.

[0012] Preferably, sliders are fixedly installed on both sides of the movable block, and the inner wall of the bracket is provided with a groove that matches the slider.

[0013] Preferably, the water outlet end of the nozzle body is threaded with a protective cap.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0016] 1. When the metal filter screen needs to be cleaned, the operator can pull the pull ring outward. The pull ring can drive the striking rod to move. The striking rod can drive the moving block to squeeze the first spring. Then the pull ring can be released. The first spring drives the moving block and the striking rod to move and strike the elastic metal strip to vibrate, thereby causing the metal filter screen to vibrate, which facilitates the cleaning of dust and impurities on the metal filter screen.

[0017] 2. When the filter cartridge needs to be cleaned, the staff can directly pull the filter cartridge outward. When subjected to external force, the semi-circular locking block can compress the second spring to retract, thereby enabling the staff to quickly pull off the filter cartridge.

[0023] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0024] This utility model provides a technical solution:

[0025] Please see Figures 1-3 A nozzle assembly structure includes a nozzle body 1, with an atomizing spray plate 10 fixedly installed at the water outlet end of the nozzle body 1. The atomizing spray plate 10 atomizes the incoming water and sprays it out. A protective cover 15 is threadedly connected to the water outlet end of the nozzle body 1. The protective cover 15 protects the atomizing spray plate 10, reducing the impact of external dust and impurities on the atomizing spray plate 10 when not in use, and also protecting the atomizing spray plate 10 from impacts by external objects.

[0026] Furthermore, a limiting block 2 is fixedly installed on the inner wall of the nozzle body 1, and a filter cylinder 3 is provided inside the nozzle body 1 on one side of the limiting block 2. An elastic metal strip 4 is fixedly installed on the inner wall of the filter cylinder 3, and metal filter screens 5 are fixedly installed on both sides of the elastic metal strip 4 inside the filter cylinder 3.

[0027] Please refer to Figure 1 and Figure 3 A bracket 6 is fixedly installed on the inner side of the elastic metal strip 4. A first spring 7 is fixedly installed on the inner top wall of the bracket 6. A movable block 8 is fixedly installed on one end of the first spring 7. A striking rod 9 is fixedly inserted inside the movable block 8. One end of the striking rod 9 contacts the elastic metal strip 4. When the striking rod 9 contacts the elastic metal strip 4, the first spring 7 is in a slightly compressed state. One end of the striking rod 9 extends to the outside of the bracket 6 and is fixedly connected to a pull ring 11. The pull ring 11 allows the operator to easily pull the striking rod 9 to move. Slider blocks 14 are fixedly installed on opposite sides of the movable block 8. The inner wall of the bracket 6 has a groove that matches the slider 14. The slider 14 and the groove can limit the movement range of the movable block 8 and make the movable block 8 move more smoothly.

[0028] Please refer to Figure 3 A second spring 12 is fixedly installed inside the filter cartridge 3. A semi-circular locking block 13 is fixedly installed at one end of the second spring 12. A semi-circular locking groove adapted to the semi-circular locking block 13 is opened on the inner wall of the nozzle body 1. When it is necessary to remove the filter cartridge 3, the operator only needs to pull the filter cartridge 3 outward. Under external pressure, the semi-circular locking block 13 can compress the second spring 12 to retract, thereby allowing the operator to quickly pull off the filter cartridge 3.

[0029] In practical use, the working principle of this utility model is as follows:

[0030] When the filter cartridge 3 needs to be cleaned, the operator can pull the filter cartridge 3 outwards. Under external pressure, the semi-circular locking block 13 can compress the second spring 12 to retract, allowing the operator to quickly pull off the filter cartridge 3. Afterwards, the operator can pull the pull ring 11 outwards. The pull ring 11 can drive the striking rod 9 to move. The striking rod 9 can drive the moving block 8 to compress the first spring 7. Finally, the pull ring 11 can be released. The first spring 7 drives the moving block 8 and the striking rod 9 to move and strike the elastic metal strip 4, thereby causing the metal filter screen 5 to vibrate, which facilitates the cleaning of dust and impurities on the metal filter screen 5.

[0031] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
