Problems solved by technology

The pump needs to be driven by a high voltage, so the cost has always been high; there are many pumps that are directly immersed in the liquid to work, because they need to be driven by a high voltage, so the insulation of the pump must be done, and it is necessary to frequently check whether the insulation facilities are damaged. As a result, the production cost is increased, the production process is complicated, and the maintenance work is increased, which is extremely dangerous; due to the large volume of the pump, it is difficult to do waterproof and anti-corrosion work, and leakage and corrosion often occur , thus bringing unsafe hazards; 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 pump, so traditional liquid spray devices require large investment and complicated maintenance

specific Embodiment approach 1

[0006] Specific implementation mode one: refer to figure 1 , the piston-type liquid spraying device driven by the shape memory alloy driver of the present embodiment includes a liquid cylinder 1, a piston 2 that can move up and down is provided in the liquid cylinder 1, and a one-way valve 2-1 is provided on the piston 2. The liquid cylinder The lower bottom of 1 is provided with an annular bottom plate 3, and a driver 4 made of a shape memory alloy material is fixedly connected between the bottom plate 3 and the piston 2, and the shape of the driver 4 is a coil spring or a rod.

[0007] Some alloys restore the high-temperature phase shape when heated, and can restore the low-temperature phase shape when cooled, which is called a two-way memory effect alloy. When the present invention uses the two-way memory effect alloy, there is no need to install a return spring. The shape memory alloy driver 4 is energized to reach the reverse phase transition point to generate expansion ...

specific Embodiment approach 2

[0009] Specific embodiment two: This embodiment is used as a fountain driven by a one-way shape memory alloy, refer to Figure 4 , The hydraulic cylinder is installed on the steering device through the bracket. The inside of the liquid cylinder 1 communicates with the water in the pool through the bottom plate 3 with the hole 3-1 in the middle, refer to figure 2 , image 3 , The upper part of the cylinder is equipped with a compression container 8 and a nozzle 9. The whole device is submerged in water, and the uppermost end of the nozzle is close to the water surface.

[0010] The driver 4 used in this embodiment is made of a shape memory alloy with one-way memory effect, and the shape of the driver 4 is a helical spring. Refer to figure 2 , image 3 , The number of helical spring-shaped shape memory alloy drivers is four, and they are connected in series in the circuit to ensure that the reverse phase transition point is reached at the same time when electrified, so tha...

specific Embodiment approach 3

[0013] Specific implementation mode three: the difference between this implementation mode and specific implementation mode two is that, refer to Figure 5 , Figure 6 , the shape of the driver 4 is a rod.

Abstract

A pi ston-type liquid spraying apparatus driven by marmem driver has a cylinder with annular bottom plate, a piston with check valve, and marmem drive between said bottom plate and piston. It features simple structure and low cost and noise.

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, so the cost has always been high; there are many pumps that are directly immersed in the liquid to work, because they need to be driven by a high voltage, so the insulation of the pump must be done, and it is necessary to frequently check whether the insulation facilities are damaged. As a result, the production cost is increased, the production process is complicated, and the maintenance work is increased, which is extremely dangerous; due to the large volume of the pump, it is difficult to do waterproof and anti-corrosion work, and leakage and corrosion often occur , thus bringing unsafe hazards; traditional large-scale liquid spraying devices often require a large number of pipes to...
