Liquid feeding device with connection part having radial long and narrow groove and liquid storage tank

Abstract

The invention discloses a device with a radially-extending connection part having a radial long and narrow groove and a liquid storage tank, which utilizes air pressure to feed out liquid. The device comprises a pressure air supplying device (7), a pressure cavity (8), a pressure supplying pipe (9), a liquid feeding-out pipeline (10) and a suctioning and filtering device (20), wherein the pressure air supplying device (7) is used for supplying pressure to the pressure cavity (8) by the pressure supplying pipe (9); the pressure cavity (8) can pressurizes the liquid in the pressure cavity (8) and conveys out the liquid through the liquid feeding-out pipeline (10); the suctioning and filtering device (20) is arranged at the inner side end of the liquid feeding-out pipeline (10) and is used for filtering the liquid while suctioning the liquid from the pressure cavity (8) by the liquid feeding-out pipeline (10); the outer side end of the liquid feeding-out pipeline (10) is used for conveying out the liquid in a flowing manner; a liquid inlet (81) is arranged at the top part of the pressure cavity (8).

Description

Technical field [0001] The present invention relates to a device that uses air pressure to give liquid, and more specifically to a device that uses air pressure to give liquid that can automatically remove flocs. Background technique [0002] The device that uses air pressure to deliver liquid is a device that sprays liquid widely used in agriculture, green field maintenance, and industry. The water quality of the device that uses air pressure to give liquid varies with the water source. Therefore, in order to prevent the normal operation of the device that uses air pressure to give liquid to be affected by impurities in the liquid, The end of the dip pipe often has a filtering structure. [0003] However, due to the suction formed by the device that uses air pressure to give liquid during operation, it is easy to absorb a large amount of impurities in the vicinity of the end of the liquid giving pipe; and some flocculent impurities will stay in the filter at the end of the liquid...

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
