Liquid dispensing device with connecting portion with radial slots and galvanized central shaft

Abstract

The invention provides a device provided with a radial extending connection part having a radial long and narrow groove and an electroplating coating central shaft and used for outputting liquid by using air. The device comprises a pressure air supplying device (7), a pressure chamber (8), a pressure supplying pipe (9), a liquid outputting pipeline (10) and a suction and filtering device (20), wherein the pressure air supplying device (7) is used for providing pressure to the pressure chamber (8) via the pressure supplying pipe (9); the pressure chamber (8) can be used for pressurizing liquid in the pressure chamber (8) and discharging the liquid through the liquid outputting pipeline (10); the suction and filtering device (20) is arranged at the inner side end of the liquid outputting pipeline (10) and is used for filtering the liquid when the liquid is sucked from the pressure chamber (8) by the liquid outputting pipeline (10); the outer side end of the liquid outputting pipeline (10) is used for discharging the liquid in a flowing manner; a liquid inlet (81) is arranged at the top of the pressure chamber (8).

Description

technical field [0001] The invention relates to a device for supplying liquid by air pressure, and more particularly relates to a device for supplying liquid by air pressure which can automatically remove flocs. Background technique [0002] The device that uses air pressure to give liquid is a kind of equipment that sprays liquid widely used in agriculture, green land maintenance and industry. The water quality used by the device that uses air pressure to give liquid varies according to the water source. Therefore, in order to prevent the device that uses air pressure to give liquid from being affected by impurities in the liquid, the device that uses air pressure to give liquid The end of the draw line often has a filter structure. [0003] However, due to the suction formed by the device that uses the air pressure to give the liquid during operation, it is easy to absorb a large amount of impurities near the end of the liquid delivery pipeline; Over time, these floccule...

AI Technical Summary

Problems solved by technology

However, in some cases, such as the maintenance of urban lawns, devices that use air pressure to deliver liquid need to draw liquid streams from some alternate liquid source, such as recycled rainwater, greywater, or even untreated ground surface Runoff water, and these devices that use air pressure to give liquid do not have the conditions for regular manual maintenance. Therefore, in this case, it is urgent to remove impurities to ensure the normal operation of the device that uses air pressure to give liquid. need
