Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to an anti-clogging nozzle with a filtering function. Background Art

[0002] The nozzle, also known as the nozzle, is a key component in many types of spraying, atomizing, oil spraying, sandblasting, spraying and other equipment. The nozzle is widely used, not only in spraying process, but also in washing and cleaning, cooling and humidification, combustion and other aspects.

[0003] When existing nozzles are spraying liquid, when the liquid contains impurities or particles, these impurities and particles may directly enter the nozzle, causing the nozzle to be blocked. If unfiltered liquid is used for a long time, the channel inside the nozzle may be gradually filled with these impurities, affecting the normal flow of the liquid and the spraying effect.

[0004] For example, a nozzle disclosed in the announcement number CN204034903U has a filter in the liquid cavity that can effectively filter out oversized particles and other impurities in the paint. However, when the filter needs to be cleaned or replaced after long-term use, it is not convenient to disassemble and assemble the filter. If the filter is not replaced in time or is difficult, the filtering effect will be affected, and then the performance and life of the nozzle will be affected.

[0005] Therefore, it is necessary to invent an anti-clogging nozzle with filtering function to solve the above problems. Utility Model Content

[0009] Preferably, a No. 1 connecting pipe is provided inside the nozzle tube body, and the No. 1 connecting pipe is arranged inside the connecting groove. The nozzle tube body and the No. 1 connecting pipe are threadedly connected, and the outer wall thread of the No. 1 connecting pipe matches the inner wall thread of the connecting groove, so that the threaded nozzle tube body and the No. 1 connecting pipe are easy to disassemble and assemble the nozzle head.

[0010] Preferably, four fixing bolts and screw holes are provided, and the four fixing bolts and screw holes are threadedly connected, so that the fixing bolts and screw holes can limit and fix the installation of the nozzle head.

[0011] Preferably, the sleeve is threadedly connected to the No. 2 connecting pipe, and both the outer wall and the inner wall of the sleeve are provided with threads. The inner wall thread of the sleeve matches the outer wall thread of the No. 2 connecting pipe, so that the threadedly connected sleeve and the No. 2 connecting pipe are easy to disassemble and assemble the filter.

[0012] Preferably, a filter screen is provided at the bottom of the sleeve, and the filter screen is fixedly connected to the sleeve by welding, so that the sleeve can limit the installation of the filter element, and the filter screen can preliminarily filter the liquid introduced.

[0013] Preferably, the filter element is designed in a cylindrical structure, and the filter element and the second connecting pipe are slidably connected. The outer wall of the filter element fits with the inner wall of the second connecting pipe, so that the filter element can perform secondary filtration on the incoming liquid to prevent impurities in the liquid from entering and clogging the nozzle head.

[0014] Preferably, the slider and the slide groove are slidably connected, and 6 sliders and slide grooves are provided, so that the sliders and the slide grooves are easy to slide and disassemble the filter element.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. Through the arrangement of the No. 1 connecting pipe and the connecting groove, the nozzle head and the nozzle body are connected by a threaded connection method through the No. 1 connecting pipe and the connecting groove, which makes the maintenance of the nozzle head and the nozzle body easier. When any of the parts is damaged or needs to be cleaned, it can be easily disassembled and replaced without replacing the entire nozzle device, which greatly reduces the maintenance cost;

[0017] 2. Through the setting of the slider and the slide groove, the filter and the No. 2 connecting pipe form a sliding connection through the slider and the slide groove. The sliding installation design allows the filter to be quickly and accurately inserted or pulled out of the slide groove, thereby greatly simplifying the installation and disassembly process. When installing the filter to prevent it from detaching from the inside of the No. 2 connecting pipe, you only need to thread the installation and tighten the sleeve to achieve stable installation of the filter.
