[0029] Reference Figure 2 An elastomer comprising:
[0030] The main body 6 has multiple vertically extending spring pieces 61, with gaps between adjacent spring pieces 61. During the up-and-down movement of the main body 6, the vertically extending spring pieces 61 are compressed or restored. The vertically extending spring pieces 61 replace traditional springs, and their elastic force is more reliable.
[0031] In a preferred embodiment, the main body 6 is a vertically arranged tube with openings at both the top and bottom. The main body 6 is used to transport fluid, and the spring pieces 61 are arranged in a ring array.
[0032] In a preferred embodiment, the longitudinal section of the spring piece 61 is arc-shaped. The spring piece 61 generates explosive force through the elastic force provided by the arc-shaped deformation, and the elastic force is relatively large.
[0033] In a preferred embodiment, the center of the spring piece 61 is far from the main body 6, while the upper and lower ends of the spring piece 61 are close to the main body 6. When the spring piece 61 deforms, its center bulges outward to store energy, resulting in a large deformation space.
[0034] In a preferred embodiment, the upper end of the spring piece 61 is integrally formed with the main body 6. Therefore, it is not necessary to install the spring piece 61 separately.
[0035] Reference Figure 3-4 A press pump, comprising the aforementioned elastomer, further comprising:
[0036] The button 4 has a liquid outlet channel with a mist point 2 at its outer end. A first spring seat 3 is mounted on the button 4, and a first spring 5 is mounted on the first spring seat 3. The top of the main body 6 is mounted on the bottom of the button 4, and a locking cover 7 is mounted in the middle of the main body 6. The bottom of the first spring 5 abuts against the locking cover 7. A secondary column 12 is mounted and connected to the bottom of the elastic body. A piston 10 is also sleeved on the lower part of the elastic body, and a spring piece 61 abuts against the piston 10. The button 4 also includes a body 11, which is sleeved on the piston 10. The top of the body 11 has a flange. The body 11 also includes a thread 8, with the flange abutting against the inner wall of the top of the thread 8. A valve 13 is also provided at the bottom of the body 11. A suction tube 14 is connected to the bottom of the body 11. The body 11 has a through hole located on the outside of the piston 10. A dust cover 1 is attached to the top of the button 4.
[0037] Among them, the spring plate 61 presses down on the piston, and the preload of the spring plate 61 can be designed to ensure the seal between the piston and the auxiliary column.
[0038] In use, install the screw thread 8 onto the bottle body of the external device, press button 4, and the mist point 2, first spring seat 3, main body 6, piston 10, and auxiliary column 12 move downwards together. The piston 10 and the main body 11 form a dynamic seal. After the piston 10 moves below the through hole, air can enter the upper part of the main body 11. The piston 10 continues to move downwards, expelling the air from the lower part of the main body 11 through the suction tube 14 into the bottle body of the external device. Afterwards, as... Figure 4 The piston 10 is restricted from moving further down by the step inside the body 11 (existing technology), while the sub-pillar 12 and the main body 6 can still move down a certain distance; then the button 4 rebounds under the action of the first spring 5 and the spring piece 61, and the body 11 draws the fluid from the external bottle through the straw 14. The fluid enters the body 6 through the gap between the sub-pillar 12 and the main body 6 (existing technology), and then the fluid is sprayed to the outside through the button 4 and the mist point 2.
[0039] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
