How it Works
The Ultra-Spray head consists of an ultrasonic transducer with a spray forming tip, an ultrasonic generator, an external liquid applicator, a precision liquid delivery system, and air directors. The ultrasonic transducer contains a spray-forming tip that vibrates at an ultrasonic frequency (> 20 kHz). The ultrasonic transducer is resonant at a particular ultrasonic frequency of 35 kHz, 45 kHz, or 60 kHz, and is driven by an ultrasonic generator with a corresponding frequency. The particular ultrasonic frequency is selected based upon the material to be sprayed and the coating application requirements. The amplitude of vibration of the spray-forming tip is also set with the ultrasonic generator.
So after that failure, the next thing I heard about was ultrasonic devices to keep cats out of the garden. When I looked into it though, my first impression was that these were gadgets that probably didn’t work. I understood the theory, . a noise that humans cannot hear, is annoying to cats, but there were a couple of concerns. Firstly, the device has to trigger, so it is reliant on a good movement detector. Secondly would it really annoy cats to the point they stopped coming around and scratching my car, or leaving cat poo in the garden?
Process: The evaporation surface (1) suctions water out of the capillary basin (6), puts the capillary pump (8) for the flooding process in action and quickly fills the surface from top to bottom. Then it drips into the catch basin (2). The water evaporates and sets the air circulation into motion. The drained water closes the hose (3) below. Here, air which flows via pipe into the water tank (5) is interrupted. The water in the tank can no longer flow out because under-pressure occurs. The residual water in the capillary basin (6), on the upper part, is evaporated by the evaporation surface (1). The residual water in the catch basin (2), on the bottom, is suctioned out by the lime separator (7) and evaporated. As soon as the catch basin is empty, air then flows again through the hose (3); water from the tank flows back to the capillary basins (6) and thereby begins the process again. The alternating filling levels for the catch and capillary basins suppress the creation of germs.
