Description

Spraying system

Technical Field

The invention relates to the field of spraying, in particular to a spraying system.

Background

At present, the ultrasonic atomizer has the defects that the particle size of water mist is very small and is generally about 1-5 microns, so the air flow resistance is poor, the local humidification and fresh-keeping effects are affected, water needs to be added frequently due to the volume limitation of a water tank, if an external water source is used, a ball float valve can be opened to inject water into the water tank, but the ball float valve has the risk of leakage and overflow, however, the smaller the particle size of the water mist is, the longer the idle time is, the better the permeability is, and a good atmosphere can be created; for example, vegetables in supermarket stores are generally kept fresh by spraying with an ultrasonic atomizer, the space humidity is increased by continuous spraying or long-time intermittent spraying, and the feeling of wonderful air drifting is created, but the air flow resistance of water mist sprayed by the ultrasonic atomizer is poor, the water mist is easy to deviate from the spraying direction of a mist outlet, the used humidity is difficult to store and adhere to the leaf surface, the farther away from the mist outlet, the less the water mist reaches, the fresh-keeping effect is poor, the long-time opening is needed, the energy consumption is high, the water consumption is large, and the utilization rate of the ultrasonic atomizer in the field of vegetable preservation is less and less at present; most storefronts only spray water through the manual watering can, the water mist particle diameter sprayed by the watering can is generally 30-200 microns, the kinetic energy is sufficient, the water mist can be mostly stuck on the leaf surface to keep the moisture of vegetables, a good fresh-keeping effect is achieved, but the vegetables need to be turned to enable the water mist to spray the vegetables inside, the operation is complex, the time is long, the frequency of water spraying and the water spraying amount cannot be well controlled due to human reasons, the fresh-keeping effect of the vegetables is poor, and the personnel cost is increased.

In addition, for example, in indoor landscape application, the landscape environment is humidified by the ultrasonic atomizer to create a humidity environment suitable for plant growth and create an atmosphere of sweet smell, but the humidity of the indoor space is too high to breed bacteria, and the high humidity is not good for health; because most of the rooms are not provided with water inlet sources, water can be added only manually to keep the normal work of the ultrasonic atomizer, and the water is added frequently, so that time and labor are wasted; the part of the place where the water inlet source is reserved or added is provided, the water inlet pipe is directly connected to a ball float valve of the ultrasonic atomizer, and the ball float valve is frequently opened and closed for a long time and bears the pressure of the water inlet source for a long time, so that leakage is easy to occur, overflow is caused, indoor water soaking is possibly caused, and economic loss is caused; because most indoor landscapes are provided with the spraying system, the particle size of the water mist sprayed by the spray head is generally 15-60 microns, and the water mist can be sprayed by a large-particle-size nozzle at a longer distance by the kinetic energy during spraying and the water mist with large particle size to water plants and wash dust on leaf surfaces, most of the water mist reaches the plants, and the overhigh humidity of the whole indoor space can not be caused; and the ultrasonic atomizer and the spraying system are independent systems and cannot be uniformly managed and assisted.
