AI Technical Summary
Existing push-type foam pumps use metal springs, which makes recycling difficult and costly, while plastic springs are easily worn out. There is a need for a low-cost and easily recyclable all-plastic elastic component.
A fully plastic elastic component was designed, including a pull rod, a piston rod, a spring rod, upper and lower springs, and a spring seat. The rapid rebound is achieved through the cup-shaped upper and lower springs and the split design. The fully plastic material is used to replace metal and plastic springs.
This results in a low-cost, easily recyclable all-plastic elastic component with better resilience and speed, enhancing its practicality.

Description
TECHNICAL FIELD
[0001] The utility model relates to foam pump technical field especially relates to a full plastic elastic piece. BACKGROUND
[0002] The full plastic elastic piece is used in the pressurized foam pump, and the pressurized foam pump in the prior art mostly uses metal springs to achieve pressurization and rebound, and the use of metal materials makes the recycling of waste foam pumps cumbersome, increasing the recycling time and cost.
[0003] Patent No. 2023212615887 provides a full plastic foam pump, but the design also has the disadvantages of high cost and easy wear of plastic springs, so a full plastic elastic piece is needed to solve the above problems. SUMMARY
[0004] The utility model embodiment aims to provide a full plastic elastic piece, aiming to solve the problems of high cost, easy wear and inconvenience of recycling of the existing plastic springs.
[0005] The utility model embodiment is implemented in the following way: a full plastic elastic piece comprises a pull rod and a piston rod, the pull rod is placed in the piston rod, and the piston rod can limit the position of the pull rod in it; a spring rod is sleeved on the piston rod, the spring rod is sleeved with an upper spring and a lower spring on the two sides, the upper spring is clamped on the piston rod on the side away from the spring rod; a spring seat is clamped on the lower spring and is provided with a center hole, a small piston passes through the center hole of the spring seat, and the small piston can be put into the piston rod and is connected with the pull rod.
[0006] Preferably, the upper spring and the lower spring are bowl-shaped, so that the upper spring and the lower spring have better elasticity.
[0007] Preferably, the spring seat has a front surface and a back surface, and the inner ring is recessed on one side as the front surface, and the small piston passes through the center hole of the front surface of the spring seat.
[0008] The full plastic elastic piece provided by the utility model replaces the plastic spring, has the advantages of low cost and good rebound force, and compared with the prior art, the one-piece structure of the elastic piece and the split design of the full plastic elastic piece, especially the addition of the spring rod, make the whole elastic piece have better rebound effect and faster speed, and the utility model has high practicability.

[0012] In the drawing: 1-pull rod, 2-piston rod, 3-spring rod, 4-upper spring, 5-lower spring, 6-spring seat, 7-small piston. DETAILED DESCRIPTION
[0013] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the utility model.
[0014] The specific implementation of the utility model is described in detail below in combination with specific examples.
[0015] Please refer to Figure 1 , Figure 2 and Figure 3 The full plastic elastic member provided by the utility model example comprises:
[0016] The pull rod 1 is placed in the piston rod 2, and the piston rod 2 can limit the position of the pull rod 1 in it; the spring rod 3 is sleeved on the piston rod 2, the spring rod 3 is sleeved with the upper spring 4 and the lower spring 5 on both sides, the upper spring 4 is clamped on the piston rod 2 away from the spring rod 3; the spring seat 6 is clamped on the lower spring 5 and is provided with a center hole, the small piston 7 passes through the center hole of the spring seat 6, and the small piston 7 can be put into the piston rod 2 and is clamped with the pull rod 1.
[0017] When assembling the full plastic elastic member, the thin end of the pull rod 1 is placed downward into the piston rod 2, and the piston rod 2 can limit the pull rod 1; the lower spring 5 is clamped on the spring seat 6, and the upper spring 4 is clamped on the piston rod 2; the upper spring 4 and the lower spring 5 are sleeved on the spring rod 3; the thin end of the small piston 7 is inserted into the middle hole of the spring seat 6, and the small piston 7 can be inserted into the piston rod 2; the small piston 7 is clamped with the pull rod 1 by pressing the small piston 7 and the pull rod 1 at the same time, and the full plastic elastic member is assembled, and the full plastic elastic member is clamped at the corresponding positions of the components.
[0018] When the foam is needed, the pressure is applied to the pull rod 1 downward by pressing, the upper spring 4 is deformed, the upper spring 4 and the downward pressure and the resistance formed by the spring seat 6 and the bottom of the pump body make the lower spring 5 deform at the same time. When the pressing force is removed, the several resistance columns of the spring rod 3 provide stronger rebound force to the bottom of the upper spring 4 and the lower spring 5, so that the upper spring 4 and the lower spring 5 are restored more quickly.
[0019] As Figure 1 , Figure 2and Figure 3 As shown in the drawings, as a preferred embodiment of the utility model, the upper spring 4 and the lower spring 5 are bowl-shaped, so that the upper spring 4 and the lower spring 5 have better elasticity.
[0020] Through the bowl-shaped design of the upper spring 4 and the lower spring 5, the deformed upper spring 4 and the lower spring 5 can recover faster.
[0021] As shown in the drawings, Figure 1 , Figure 2 and Figure 3 As shown in the drawings, as a preferred embodiment of the utility model, the spring seat 6 is divided into front and back surfaces, and the inner ring is recessed on one surface as the front surface, and the small piston 7 is inserted through the center hole of the front surface of the spring seat 6.
[0022] The spring seat 6 is divided into front and back surfaces, and the inner ring is recessed on one surface as the front surface, and the other surface is the back surface, and the thin head of the small piston 7 is inserted through the middle hole of the front surface of the spring seat 6.
[0023] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
