[0033] Refer to Figure 1 、 Figure 3 and Figure 5, A spray pump with a plastic spring according to an embodiment of the first aspect of the present utility model includes a pressing assembly 100, a piston member 200, a lower housing 300, a first plastic spring 400 and a second plastic spring 500. The pressing assembly 100 has a fluid passage 110, and a feed port 111 communicating with the fluid passage 110 is provided at the lower part of the pressing assembly 100. The piston member 200 is slidably disposed at the lower part of the pressing assembly 100. The lower housing 300 is provided with an upwardly opening mounting groove and a one-way suction port 310 communicating with the outside. The pressing assembly 100 is slidably connected to the mounting groove, and the piston member 200 and the mounting groove enclose a pump suction cavity 320. The one-way suction port 310 can limit the outward flow of the material in the pump suction cavity 320. The first plastic spring 400 includes a first support ring 410 arranged from top to bottom, a plurality of inclined first elastic rings 420 and a second support ring 430. The bottom of the first support ring 410 is connected to a corresponding first elastic ring 420, and the top of the second support ring 430 is connected to a corresponding first elastic ring 420. Each first elastic ring 420 is connected end to end, and the inclined directions of two adjacent first elastic rings 420 are opposite. The first support ring 410 abuts against the sliding assembly, and the second support ring 430 abuts against the lower housing 300. The first plastic spring 400 can drive the sliding assembly to slide upward. The top of the second plastic spring 500 abuts against the sliding assembly, and the bottom abuts against the piston member 200. The second plastic spring 500 can drive the piston member 200 to move downward to block the feed port 111. When the pressing assembly 100 is pressed, the piston member 200 can be driven to move downward to compress the pump suction cavity 320. Since the one-way suction port 310 restricts the outward flow of the material therein, the material in the pump suction cavity 320 can only drive the piston member 200 to slide upward and compress the second plastic spring 500. At this time, the piston member 200 can open the feed port 111, and the material can enter the fluid passage 110 so that it can be ejected outward. After ejection, the pressure in the pump suction cavity 320 drops, and the second plastic spring 500 can drive the piston member 200 to slide downward to block the feed port 111 again, while the first plastic spring 400 can drive the pressing assembly 100 to slide upward to reset. The first plastic spring 400 is supported by the first support ring 410 and the second support ring 430, and the first elastic rings 420 arranged in reverse inclination in sequence in the middle can provide better elastic force.

[0034] Specifically, both the pressing component 100 and the lower housing 300 can be made of plastic material, so that the overall spray pump can be made of plastic parts, which is convenient for recycling. When in use, after pressing the pressing component 100, the piston member 200 can be driven to compress the pump suction cavity 320 downward, and the one-way suction port 310 restricts the outward flow of the material. Therefore, the material in the pump suction cavity 320 drives the piston member 200 to compress the second plastic spring 500 upward. After the piston member 200 slides upward, the feed port 111 can be opened, and the material can enter the fluid passage 110 and be ejected. After the ejection is completed, the pressure in the pump suction cavity 320 drops, and the second plastic spring 500 can drive the piston member 200 to slide downward to re-block the feed port 111. At this time, the first plastic spring 400 can drive the pressing component 100 to reset and rise. At this time, the one-way suction port 310 can suck the material into the pump suction cavity 320. The first plastic spring 400 can be arranged with a first support ring 410 horizontally disposed and a second support ring 430 vertically disposed, and between them, a first elastic ring 420 is arranged in a reverse inclined manner in sequence. When the first plastic spring 400 is compressed, each first elastic ring 420 can approach and fold each other, providing a large elastic force, enabling the pressing component 100 to be fully reset, which is convenient for users to use.

[0035] Referring to Figure 2 , Figure 4 and Figure 6 , in some embodiments of the present invention, the first plastic spring 400 further includes a plurality of second elastic rings 440 arranged obliquely. The second elastic rings 440 are connected end to end from top to bottom, and the second elastic rings 440 are arranged crosswise with the corresponding first elastic rings 420. The second elastic rings 440 can cooperate with the first elastic rings 420, which can improve the structural strength and also enhance the elastic force.

[0036] Specifically, the inclination direction of the second elastic ring 440 can be set opposite to that of the first elastic ring 420, so that the second elastic ring 440 can be arranged crosswise with the first elastic ring 420, and the first elastic ring 420 and the second elastic ring 440 form an X-shaped elastic structure, which can improve the structural strength, making it not easily damaged, and can also enhance the elastic force, further facilitating the reset of the pressing component 100 and being convenient for users to use.

[0037] It can be understood that the first plastic spring 400 can be an integral structure.

[0038] In some embodiments of the present utility model, the second plastic spring 500 includes a third support ring 510, a plurality of obliquely arranged third elastic rings 520, and a fourth support ring 530 arranged from top to bottom. The third support ring 510 abuts against the pressing assembly 100, and the fourth support ring 530 abuts against the piston member 200. Each of the third elastic rings 520 is connected end to end, and the inclination directions of two adjacent third elastic rings 520 are opposite. This can improve the elastic force of the second plastic spring 500 and facilitate user operation.

[0039] Specifically, the second plastic spring 500 is used to drive the piston member 200 to slide to block or open the feed port 111. The third support ring 510 and the fourth support ring 530 can be horizontally arranged, and a plurality of third elastic rings 520 are connected between them. The third elastic rings 520 are also arranged obliquely in opposite directions in sequence. Similarly, the above structure can improve the elastic force of the second plastic spring 500 and facilitate user operation.

[0040] Refer to Figure 7 In some embodiments of the present utility model, the second plastic spring 500 further includes a plurality of obliquely arranged fourth elastic rings 540. The fourth elastic rings 540 are connected end to end from top to bottom, and the fourth elastic rings 540 are arranged in a crossed manner with the corresponding third elastic rings 520. This can improve the structural strength, making it not easily damaged, and can also enhance the elastic force.

[0041] Specifically, the fourth elastic rings 540 can be arranged obliquely in the opposite direction to the third elastic rings 520, and the fourth elastic rings 540 can be arranged in a crossed manner with the third elastic rings 520 to form an X-shaped elastic structure, which can improve the structural strength, making it not easily damaged, and can also enhance the elastic force.

The plunger 130 can be inserted into the opening at the bottom of the sliding pipe fitting 120, and corresponding grooves can be provided on the plunger 130 so that there is a gap between the plunger 130 and the sliding pipe fitting 120. Materials can enter the fluid passage 110 through the gap. The gap is the feed port 111. The plunger 130 can be provided with a positioning portion extending outward. The piston member 200 can abut against the positioning portion to block the gap. When the piston member 200 slides upward, the gap can be reopened, thereby opening the feed port 111, which can facilitate pressure-holding spraying.

[0044] It is understandable that the sliding pipe fitting 120 can also be provided with a feed inlet 111 on the side wall and the end portion is blocked and arranged.
