Embodiment Construction
[0028] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] A rotorless jet spray fan includes a power supply control system 2, a jet exciter 1, a liquid supply system 3 and a delay trigger 4.
[0030] The jet actuator 1 includes a casing 1.1, and the casing 1.1 is provided with a vibrating membrane 1.2. In this embodiment, the vibrating membrane 1.2 is a piezoelectric vibrating membrane, and its vibration is driven by piezoelectricity. The vibrating membrane 1.2 divides the cavity in the housing 1.1 into two independent cavities, respectively the first cavity 1.3 and the second cavity 1.4, and the top wall of the corresponding housing above the first cavity 1.3 is provided with There is a first jet actuator outlet channel 1.5, and a second jet actuator outlet channel 1.6 is provided on the corresponding top wall of the casing above the second cavity 1.4.
[0031] The vibrating membrane 1.2 in t...
