A second outer flange 505 is provided at the lower end of the connecting cover 5, and the second outer flange 505 is inserted into the interior of the pump body 1 and cooperates with the inner groove 102 to clamp the connecting cover 5 on the pump body 1. The bottom of the connecting cover 5 is used to limit the piston 4.

[0043] 11-12 , the valve stem 6 includes a rod body 601 and a boss 602 . The diameter of the boss 602 is larger than the diameter of the rod body 601 . After the valve stem 6 is connected to the push cap 9 , the upper end face of the boss 602 contacts the push cap 9 , and the lower end face of the boss 602 is provided with a limiting groove 603 . The limiting groove 603 is annular and is used to limit the upper end of the spring piece 7 . A fixing groove 604 is provided on the upper inner wall of the rod body 601 . After the rod body 601 is connected to the push cap 9 , the fixing groove 604 cooperates with the push cap 9 to fix the valve stem 6 and the push cap 9 . An inner rib 605 is provided on the inner wall of the rod body 601 . The valve needle 3 is inserted into the rod body 601 , and the inner rib 605 is embedded in the annular groove 304 to fix the valve needle 3 to the valve stem 6 .

[0044] 13-14, the spring piece 7 is a hollow columnar structure, the upper end of the spring piece 7 is provided with an upper support portion 702, the upper support portion 702 is used to insert into the limiting groove 603, the lower end of the spring piece 7 is provided with a lower support portion 702, the lower support portion 702 is used to insert into the upper support groove 503, the spring piece 7 is limited by the connecting cover 5 and the valve stem 6, and when the pressing cap 9 is squeezed to drive the valve stem 6 to move upward, the upper support portion 702 and the lower support portion 702 of the spring piece 7 are supported and limited by the limiting groove 603 and the upper support groove 503. On the one hand, , to prevent the upper and lower ends of the shrapnel 7 from being misaligned, causing the shrapnel 7 to lose its supporting elastic force. On the other hand, the air inside the hollow cylindrical structure of the shrapnel 7 is not easy to flow out, and the air pressure increases. When used in conjunction with the shrapnel 7, it has a large elastic force, which is conducive to the ejection of the contents when pressed. When the press cap 9 is released, the shrapnel 7 itself and the air pressure are used to facilitate the reset of the shrapnel 7, which is in turn conducive to the reset of the press cap 9 and the entry of the contents into the piston 4 and the bottom of the pump body 1 to form a cavity structure with a large elastic force, better sealing, and no leakage.

[0045] Furthermore, a raised portion 701 is provided in the middle of the spring piece 7, and the raised portion 701 is an arc surface. A first inclined surface 704 is provided at the connection between the raised portion 701 and the upper support portion 702, and the first inclined surface 704 is a conical surface. The diameter of the spring piece 7 extending axially from the raised portion 701 to the upper support portion 702 gradually decreases, and a second inclined surface 705 is provided at the connection between the raised portion 701 and the lower support portion 703. The second inclined surface 705 is an inverted conical surface. The diameter of the spring piece 7 extending axially from the raised portion 701 to the lower support portion 703 gradually decreases. When the pressing cap 9 is pressed downward, the valve stem 6 moves downward, squeezing the upper support portion 702, and the first inclined surface 704 squeezes the raised portion 701 downward. The portion 701 expands outward, thereby compressing the spring piece 7. Because the diameter of the spring piece 7 at the raised portion 701 is larger than the diameters at the first inclined surface 704 and the second inclined surface 705, the raised portion 701 is relatively flexible, and the first inclined surface 704 and the second inclined surface 705 are harder than the raised portion 701. The provided raised portion 701 facilitates compression of the spring piece 7, and the provided first inclined surface 704 and the second inclined surface 705 facilitate restoration of the spring piece 7 from the compressed state. When the push cap 9 is released, the spring piece 7 is restored, pushing the valve stem 6 to move upward and restore. The plastic spring 7 replaces the metal spring, which facilitates the recycling of the perfume pump and meets the requirements of environmental protection and energy saving.

[0046] 15-16 , a sleeve 1001 is provided inside the large circle 10, and a support ring 1002 is provided inside the sleeve 1001. The support ring 1002 is used to support the connecting cover 5. A card groove 1005 is provided on the inner wall of the sleeve 1001. The connecting cover 5 is inserted into the sleeve 1001, and the first outer flange 502 is embedded in the card groove 1005 to connect the connecting cover 5 to the large circle 10. An annular groove 1003 is provided between the sleeve 1001 and the inner wall of the large circle 10. The annular groove 1003 is used to limit the horizontal direction of the press cap 9 to reduce the shaking caused by pressing the press cap 9. An internal thread is provided at the opening at the lower end of the sleeve 1001 for connecting to the bottle body.

[0047] In another embodiment, a bottle body is provided, wherein an external thread is provided at an opening of the bottle body, and the bottle body is connected to an all-plastic perfume pump and a bottle body therefor, for storing perfume.

[0048] The working principle of the present invention is:

[0049] When the perfume pump is in use, the large ring 10 is connected to the bottle body, and the gasket 11 is located at the opening of the bottle body to play a sealing role. The pressing cap 9 is pressed downward to drive the valve stem 6 to move downward, and the valve needle 3 and the piston 4 to move downward. The valve stem 6 and the connecting cover 5 squeeze the spring piece 7, squeezing the contents in the cavity structure formed by the piston 4 and the bottom of the pump body 1. At this time, the plastic beads 2 are subjected to downward pressure to block the bottom of the pump body 1, and the cavity structure increases. The contents push the piston 4 upward, and the valve needle 3 continues to move downward under the external pressure. The space in the cavity structure gradually decreases, so that the sealing cone 402 is separated from the sealing ring 305 and the liquid inlet 302 is exposed. The contents in the cavity structure enter the liquid outlet 303 from the liquid inlet 302, and then pass through the valve stem 6 and the pressing cap 9 and are sprayed out from the spray piece 8 in a mist form. After the bottom surface of the pressing cap 9 contacts the bottom surface of the annular groove 1003, the pressing cap 9 stops moving upward, completing one spraying.

[0050] Release the button cap 9, the spring 7 extends, pushing the valve stem 6 to move upward, driving the valve needle 3 to move upward, the space of the cavity structure gradually increases, and negative pressure is generated in the cavity structure. Under the action of atmospheric pressure, the contents inside the bottle body follow the straw 12 and push the plastic beads 2 into the cavity structure. Because the plastic beads 2 are lighter than glass beads in the same volume, the plastic beads 2 can be separated from the bottom interface of the pump body 1 under a smaller content pressure, realizing feeding. When the pressure inside the cavity structure and the pressure inside the bottle body are balanced, the sealing ring 305 of the valve needle 3 fits against the sealing cone 402 of the piston 4, and the contents will not flow back into the bottle body. At this time, the cavity structure is used to temporarily store the contents until the next spraying.

[0051] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
