Description

Technical Field

[0001] The utility model relates to the field of direct injection nozzles, in particular to a pressurized direct injection nozzle. Background Art

[0002] Direct-injection nozzles are an important sprayer accessory, widely used in agriculture, cleaning, disinfection, and other fields. They come in a variety of types, including electric sprayer nozzles, manual knapsack nozzles, and copper spray guns. Common materials include plastic and copper. Direct-injection nozzles primarily spray liquid in a mist-like form, offering excellent atomization and uniform spray. Some nozzles also feature adjustable atomization to suit different needs. In agriculture, in particular, direct-injection nozzles greatly facilitate pesticide spraying.

[0003] The common direct injection nozzles on the market contain a large amount of impurities in the pesticides. Therefore, after long-term use, the impurities inside the device are carried to the nozzle by the sprayed liquid, causing uneven spray from the nozzle. The residual impurities inside the nozzle are not easy to remove, and cleaning takes a long time, which reduces the working efficiency of the device. Utility Model Content

The lower surface of the first protrusion is fixedly connected to the inner wall of the shell. A filter screen is installed on the surface of the first protrusion. The inner wall of the filter screen is provided with a threaded groove.

[0010] As a further description of the above technical solution:

[0011] A connecting groove is provided on the upper surface of the shell, and a cleaning cover is movably connected to the inner wall of the connecting groove. The cleaning cover is located above the filter screen. A water inlet pipe is fixedly connected to the upper surface of the shell, and the water inlet pipe is located on the left side of the cleaning cover.

[0012] As a further description of the above technical solution:

[0013] A pressurizing mechanism is installed on the right side surface of the shell, and the pressurizing mechanism includes an air pump. The left side surface of the air pump is fixedly connected to the right side surface of the shell, and the output end of the air pump is fixedly connected to a connecting pipe, and the end of the connecting pipe is fixedly connected to the upper surface of the connecting shell.

[0016] The utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, this pressurized direct-injection nozzle, through the nozzle, elastic block, and nozzle plate, in use, the water in the shell enters the connecting shell through the water outlet pipe, the air pump installed on the right side of the connecting shell pressurizes the device, and a second through hole with a larger upper part and a smaller lower part is opened on the nozzle plate fixed on the inner wall of the connecting shell to accelerate the flow rate of water and further increase the pressure. An elastic block is installed between the nozzle plate and the nozzle. During long-term use, impurities inside the device flow from the shell into the connecting shell, and then pass through the second through hole and finally remain between the nozzle and the elastic block. When the nozzle is clogged, it is only necessary to press the nozzle downward in the direction of the nozzle plate so that the second protrusion fixed on the surface of the nozzle is detached from the connecting shell.

The filter screen is located above the water outlet pipe, so that larger impurities in the outer shell will not enter the interior of the water outlet pipe. When the filter screen needs to be cleaned after using it for a period of time, since the inner wall of the filter screen is provided with a threaded groove, it is only necessary to open the cleaning cover on the surface of the outer shell and unscrew the filter screen. The filter screen can be taken out from the connecting groove on the surface of the outer shell and installed inside the device after cleaning for easy cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
