Liquid dispensing device with layered structure sealing strip and liquid storage tank

Abstract

The invention discloses a liquid feeding device with a sealing strip with a layered structure and a liquid saving box. The liquid feeding device comprises a pressure air feeding device (7), a pressure cavity (8), a pressure feeding pipe (9), a liquid feeding pipeline (10) and an adsorbing filtering device (20), wherein the pressure air feeding device (7) is used for providing pressure for the pressure cavity (8) through the pressure feeding pipe (9); the pressure cavity (8) is capable of pressurizing liquid in the pressure cavity (8) and sending the pressurized liquid out through the liquid feeding pipeline (10), and the adsorbing filtering device (20) is arranged on the inner side end of the liquid feeding pipeline (10) and is used for filtering the liquid when the liquid feeding pipeline (10) absorbs the liquid from the pressure cavity (8); the outer side end of the liquid feeding pipeline (10) is used for sending out the liquid in a flowing manner, and the top of the pressure cavity (8) is provided with a liquid inlet (81).

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
