Ultrasonic humidifying device capable of realizing quasi-stepless regulation and control strategy

Abstract

The invention discloses an ultrasonic humidifying device capable of realizing quasi-stepless regulation and a control strategy. The ultrasonic humidifying device comprises a shell, an ultrasonic spraying array, a variable-frequency fan, a water pump and a spraying amount controller; a water storage tank and an atomization tank are arranged at the bottom in the shell; the atomization tank is located above the water storage tank; the water pump is arranged in the water storage tank; a water outlet of the water pump communicates with the atomization tank; the ultrasonic spraying array is arrangedat the bottom of the atomization tank; the fan is arranged at the top in the shell and is located above the ultrasonic spraying array; and the spraying amount controller is connected with the ultrasonic spraying array. The device can realize uniform and quasi-stepless control on water mist spraying, ensures that the water mist uniformly flows out along with airflow, and is of important significance in researching the influence of uniform fine-particle water mist with different flows on the performance of a filter and the influence on the surrounding environment.

Description

technical field [0001] The invention relates to a quasi-stepless-adjustable ultrasonic humidifying device, which belongs to the technical field of ultrasonic humidification. Background technique [0002] Existing spray devices for industrial or service industries all use simple multi-head unified control spray, such as parks or performance venues to create a dreamy effect of water mist, or production environments that require humidification, so there are requirements for spray range control and water volume requirements not tall. [0003] At present, the ultrasonic humidifiers on the market have the following problems: 1. It is difficult to achieve precise control of different water levels; 2. Due to the small number of fans and the lack of deflectors, it is difficult to achieve a uniform flow field near the fogging water surface ; 3. Generally, 8-10 ultrasonic fogging piezoelectric blocks are uniformly controlled, and it is difficult to achieve individual control; 4. The f...

Problems solved by technology

[0003] At present, the ultrasonic humidifiers on the market have the following problems: 1. It is difficult to achieve precise control of different water levels; 2. Due to the small number of fans and the lack of deflectors, it is difficult to achieve a uniform flow field near the fogging water surface ;3. Generally, 8-10 pieces of ultrasonic fogging piezoelectric blocks are uniformly controlled, and it is difficult to achieve individual control; 4. The fog droplet outlet is generally set as 2-3 circular tube outlets, resulting in uneven mixing of fog droplets at the outlet section

Therefore, the existing spray device is not suitable for application scenarios with high spray requirements
