Pump and valve integrated single-motor double-acting pressure flow precise control valve for flower watering

Abstract

The invention discloses a pump and valve integrated single-motor double-acting pressure flow precise control valve for flower watering. When a pressure sensor in a water tank detects that a water pressure is insufficient or does not reach a preset value, a device automatically switches on an air pump traction electromagnet, an air compression pump works to compress air into the water tank; if the pressure detection in the water tank meets the requirement of the preset value, the air compression pump stops pumping the air; precise control of flow is realized by utilizing a long and narrow micro-channel among an upper hole of a flow adjustment valve, a lower hole of the flow adjustment valve, and an intermediate adjustment hole corresponding to a flow adjustment rod according to the soil moisture content given by a humidity sensor in a flowerpot; the precision of flow control is guaranteed by constant pressure and fine adjustment of the displacement of a slit. According to the pump and valve integrated single-motor double-acting pressure flow precise control valve for flower watering, flower watering water supply and flow adjustment are integrated; the constant pressure of the water tank is realized through the air compression pump; precise control of a watering water amount is realized through the flow adjustment; an air pumping cylinder and the flow adjustment valve are integrated, so that air pumping and watering double-acting switching control is realized through one power source.

Description

technical field [0001] The invention relates to a valve, in particular to a fine pressure and flow control valve for watering flowers. Background technique [0002] With the change of people's life rhythm and lifestyle, it often happens that the plants in the home are left unattended or have no time to carefully maintain them, or due to lack of experience, the humidity of the plants cannot be accurately grasped, resulting in poor plant maintenance. In this case, people usually choose a flower waterer instead of manual watering. [0003] However, conventional flower waterers generally do not have a water tank, and the water supply power directly depends on the tap water pressure. For balcony gardening, a separate external water source is required, which causes great limitations; or some flower waterers can be equipped with a water tank, but there is no pressure, and the water tank is often placed At high places, rely on the water's own weight to generate power to water the f...

AI Technical Summary

Problems solved by technology

First, there is no water tank or the pressure of the water tank is unstable; second, the valve body used is only used as a switch, and it is impossible to use the valve to achieve fine control of flow and realize fine maintenance of plants

And the first problem - the pressure is not constant, which will also cause the flow to be unable to be finely controlled
