Problems solved by technology

At the same time, when the micro-sprayer sprays the suspension, since the suspension generally contains particles, the existence of particles will affect the airtightness of the micro-valve, so the existing micro-valve structure still needs to be improved.

Abstract

The invention belongs to the field of sprayers, and particularly relates to a micro piezoelectric sprayer for suspension liquid. A liquid storage bag is connected to a base; suspension liquid is provided in the liquid storage bag; a base, an upper cover, a housing, a middle layer and an end cover are sequentially connected from top to bottom; a first piezoelectric vibrator is mounted between the upper cover and the housing; an inlet channel is arranged inside the upper cover, the base and the housing, and the tail end of the inlet channel is equipped with a soft valve; the housing is equippedwith a pump cavity; a second piezoelectric vibrator is mounted between the middle layer and the end cover; a medium cavity is arranged inside the middle layer; the medium cavity communicates with thesecond piezoelectric vibrator and the soft valve; an outlet channel is arranged inside the housing, the middle layer and the end cover; and one end of the outlet channel communicates with the pump cavity, and the other end of the outlet channel communicates with the spray nozzle. The micro piezoelectric sprayer has the features and the advantages of being small in energy consumption, low in cost,simple in structure, easy in integration and convenient in carrying, can realize spraying of suspension liquid; and the spray head is equipped with a slender channel and an energy storage cavity, so that gas bubbles can be prevented from entering the pump cavity.

Description

technical field [0001] The invention belongs to the field of sprinklers, in particular to a micro piezoelectric sprinkler for suspension. Background technique [0002] Sprayer has been widely used in fields such as agriculture and forestry, horticulture, fire protection, medical treatment as a kind of commonly used device, has proposed a kind of lawn sprinkler as Chinese patent CN107711445A, and it has improved spraying area by arranging rotary table; Chinese patent CN207613018U has proposed a A pesticide sprayer, which automatically outputs pesticides through a submersible pump, replaces the traditional manual spraying, and greatly improves work efficiency. However, there are still some deficiencies in existing sprinklers, for example: 1. Traditional sprinklers require external pressure to work, and cannot work in an environment without water pressure; 2. Sprinklers are driven by motors, with complex structures, low integration, and large volume And high power consumption....
