Description

Filter device for micro-mist nozzle

technical field

The utility model relates to a filter device for a micro-mist spray head, that is, a filter unit that can filter sediment or impurities contained in water is installed in the sprayer, which can prevent the spray head from being blocked and keep the spraying going smoothly, reducing maintenance Operation and growth in service life.

Background technique

Generally, micro-mist nozzles usually introduce water directly into the spray head through pipelines and pipe joints, and then spray it out in the form of water mist from the fine nozzle holes. This water mist is usually used to cool down the environment or irrigate plants. However, due to the mist-like water itself (especially the extracted groundwater) or the uncleanness in the pipeline, it may contain fine sediment and impurities, which will cause the nozzle hole of the spray head to be blocked. It affects the progress of the application work, and when the nozzle hole is severely blocked, it is difficult and time-consuming to clean up, which will increase the cost of maintenance. Therefore, it is usually directly replaced with a new spray head, but this also causes unnecessary waste of cost.

Utility model content

Therefore, in order to improve the aforementioned known micro-mist nozzles that may cause nozzle clogging due to sediment or other impurities in the water, the utility model provides a spray head that is itself provided with a filter unit, and the spray head The lower end or itself is connected or extended with a connecting pipe (part) that can be connected with various pipe joints, so that the sediment or impurities contained in the water can be filtered through the filter unit, so that the probability of blockage in the spray head or nozzle hole can be greatly reduced. decrease in magnitude.

The technical scheme adopted by the utility model to solve the technical problems is: to propose a filter device for a micro-mist spray head, which is characterized in that it includes a spray end with at least one spray head capable of spraying water mist, and a connecting It is provided at the lower end of the spraying end and can be connected to the jointing end on the pipeline, and a hollow cylindrical filter unit is connected to the lower end of the spray head, and the filter unit is accommodated in the jointing end.

In the above solution, the filter unit includes a hollow pipe portion with a hollow ring provided with a filter net, and the upper end of the hollow pipe portion is provided with an external threaded portion capable of being screwed into the screw hole provided at the lower end of the spray head.

In the above scheme, the joint end is a connecting pipe that is separated from the spray head and can completely accommodate the filter unit, and the upper end of the connecting pipe is provided with an external screw joint that can be screwed to the lower end of the spray head. The screw hole, and the lower end of the connecting pipe is also provided with an external screw joint.

In the above solution, the joint end is extended from the lower end of the spray head itself to accommodate the filter unit, and the lower end of the filter unit is slightly exposed to a connecting part, and the lower end of the connecting part is provided with an external threaded part.

In the above-mentioned solution, the joint end is extended from the lower end of the spray head itself to accommodate the filter unit, and the lower end of the filter unit is slightly exposed to a connecting part, and a fast-moving valve is provided in the middle of the outer periphery of the connecting part. Connector groove.

The beneficial effect of the utility model is that, through the filter unit installed in the above-mentioned sprayer, the sediment or impurities contained in the water will not enter into the spray head and cause blockage, and at the same time, the water flow into the micro-mist spray head will pass through the high-pressure auxiliary filter. Therefore, when the strong water flow passes through the filter screen of the filter unit, it has the effect of cutting impurities or sediment, so that the particles of impurities or sediment become smaller and can pass through the filter screen, and because the aperture of the spray hole is always larger than the filter screen of the filter screen The design of the hole can prolong the time for impurities or sediment to completely block the filter screen, which can not only increase the service life of the sprayer, but also reduce the cost of maintenance operations. At the same time, the filter unit can be reused after being removed and cleaned. Reduce the replacement and waste of unnecessary components.
