specific Embodiment approach 1

[0021] Specific implementation mode one: see Figure 1~3 , the liquid injection device of this embodiment is composed of a cavity 1, a nozzle 2, a liquid inlet valve 3, a shape memory alloy driver 4, a limit post 5 and a limit pull wire 6, the cavity 1 is connected to the nozzle 2, and the type The cavity 1 is jointly surrounded by a dynamic pressure plate 1-1, a flexible side skin 1-2 and a static pressure plate 1-3, and the left end surface and the right end surface of the flexible side skin 1-2 are respectively connected with a dynamic pressure plate 1-1 and a static pressure plate. The pressure plate 1-3, the shape memory alloy driver 4 and the limit pull wire 6 are connected between the dynamic pressure plate 1-1 and the static pressure plate 1-3, and the limit column 5 is installed on the inner end surface of the static pressure plate 1-3, and the The liquid valve 3 is installed on the static pressure plate 1-3 and communicates with the cavity 1. The liquid inlet valve ...

specific Embodiment approach 2

[0024] Specific implementation mode two: see Figure 4~6 The difference between this embodiment and the first embodiment is that it also includes a return spring 7, the return spring 7 is located between the dynamic pressure plate 1-1 and the static pressure plate 1-3, and the shape memory alloy driver 4 is a one-way shape memory Alloy drive. Since the one-way shape memory alloy only has the function of memorizing the shape of the high-temperature parent phase, when the temperature is lowered to make it in the low-temperature martensitic phase state, it cannot change its shape spontaneously, and only with the help of external force can the two-way action be realized. This embodiment is realized by means of return springs 7, wherein the number of return springs is three or more.

[0025] working principle:

[0026] The whole liquid spraying device is submerged in the liquid, and the nozzle 2 can also protrude out of the liquid surface. When working, the shape memory alloy dri...

specific Embodiment approach 3

[0027] Specific implementation mode three: as Figure 7-10As shown, this embodiment is a flexible cavity liquid injection device that feeds liquid from the back of the static pressure plate 1-3, and the one-way liquid inlet valve 3 is located at the back of the static pressure plate 1-3. When the cavity 1 expands, the one-way liquid inlet valve 3 is opened to realize liquid inlet from the back. Due to the larger area of ​​the back of the static pressure plate 1-3, a larger liquid inlet can be opened to realize rapid liquid inlet and increase the frequency of liquid spraying.

Abstract

A liquid spraying apparatus with flexible cavity and driven by marmem is composed of a cavity consisting of movable and fixed pressing plates and flexible jacket, nozzle, liquid inlet valve, the marmem driver and limiting pull string between said movable and fixed pressing plates, and limiting post on the inner surface of said fixed pressing plate. It features simple structure and no electric leakage.

Description

Technical field: [0001] The invention relates to a liquid spraying device. Background technique: [0002] Traditional liquid spraying devices (such as fountains) generally use a pump as a power device to accelerate the liquid to achieve spraying. The pump needs to be driven by a high voltage, and some pumps are directly immersed in the liquid, and leakage may occur. The waterproof and anti-corrosion of the pump are also important considerations. Traditional large-scale liquid spray devices often require a large number of pipes to connect nozzles and pumps to transmit the liquid pumped by the pumps, and the structure is relatively complicated. Invention content: [0003] The object of the present invention is to provide a flexible cavity liquid spraying device driven by shape memory alloy, which uses the shape memory alloy driver to be energized and heated to shrink the flexible cavity, and presses the liquid in the cavity to spray out from the nozzle to realize liquid spr...
