Automatic drip irrigation emitter

Abstract

The invention discloses an automatic drip irrigation emitter which belongs to an irrigation device for cultivating potted flowers. The automatic drip irrigation emitter comprises a water storage bottle composed of a bottle body and a bottle cap, and a water outlet pipe, and is characterized in that an air inlet pipe is arranged in the automatic drip irrigation emitter, wherein one end of the air inlet pipe is communicated with the bottom of the bottle body, and the other end is opened in the atmosphere; a water outlet connector communicated with an inner cavity of the bottle body is arranged at the bottom of the bottle body; the water outlet pipe sleeved on the water outlet connector is hermetically communicated with a cavity for observing a drip irrigation speed; a lower opening of the observing cavity is hermetically communicated with a weeping pipe; and a pipe clamp for controlling the drip irrigation speed is sleeved on the periphery of the weeping pipe. The inner cavity of the bottle cap is in threaded connection with the periphery of an upper opening of the bottle body. Position height of one end of the air inlet pipe opened in the atmosphere is greater than that of the upper opening of bottle body. The water outlet pipe, the observing cavity and the weeping pipe are processed into hermetically integrated and elastic transparent flexible pipes by using an injection molding method. The pipe clamp is composed of a pipe clamp body with an inclined raceway, and a roller wheel in the inclined raceway. Probation shows that the automatic drip irrigation emitter is simple and practical, suitable for cultivation and conservation of the potted flowers, and visual and convenient to control the drip irrigation speed.

Description

technical field [0001] The invention belongs to a potted flower cultivation water irrigation device, in particular to an automatic drip irrigation device for drip-irrigating the cultivation water into the pot soil at the root of the potted flower. Background technique [0002] Existing watering devices for potted flower cultivation, such as a drip irrigation device for domestic flower cultivation disclosed in document 1 ZL 200720169551.6, include a container, a conduit, and a water flow control device. An opening is arranged on the top of the container, and the conduit is connected to the bottom of the container. on the catheter. The water outlet end of the conduit is connected with a conduit fixing clip, and the water flow control device is an infusion tube clip or a throttle valve. [0003] The drip irrigation device for domestic flower cultivation disclosed in Document 1, on the one hand, lacks an air inlet pipe with one end connected to the bottom of the container and t...

AI Technical Summary

Problems solved by technology

[0003] The drip irrigation device for domestic flower cultivation disclosed in Document 1, on the one hand, lacks an air inlet pipe with one end connected to the bottom of the container and the other end open to the atmosphere, so it is impossible for the cultivation water in the airtight container to drip out from the conduit. That is to say, it cannot be used in practice; on the other hand, the catheter lacks an observation cavity for observing the drip irrigation speed, which is very inconvenient for controlling the drip irrigation speed
