[0033] In the present invention, the piston 7 is aligned with the inner wall of the pump chamber 1 in a single linear manner, effectively reducing friction between the piston 7 and the pump chamber 1, thereby greatly improving the pressing feel. In the present invention, an upper spring 8 is provided between the pump rod and the piston 7, and a lower spring 9 is provided between the lower pump rod 5 and the pump chamber 1, thereby ensuring fast pumping and stable discharge volume.

[0034] The lower pump rod 5 described in the present invention includes a cylindrical lower pump rod body 51, an annular end head 52 is provided at the lower end of the lower pump rod body 51, an annular groove 53 that can be sealed with the piston 7 is provided at the upper end of the annular end head 52, a notch 55 that can form a conveying channel 54 with the outer wall of the upper pump rod 6 is provided on the outer wall of the lower pump rod body 51, an external buckling portion 56 is provided at the upper end of the lower pump rod body 51, and the upper pump rod 6 includes an upper pump rod body 61, an internal buckling portion 62 is provided on the inner wall of the middle part of the upper pump rod body 61, the external buckling portion 56 is buckled on the internal buckling portion 62, and a conducting notch 63 is provided on the internal buckling portion 62 along the axial direction of the upper pump rod 6. In the present invention, the upper end surface of the annular end head 52 is provided with a liquid introduction groove 57 connected to the notch 55. The liquid in the pump chamber 1 can enter the delivery channel 54 surrounded by the notch 55 on the outer wall of the lower pump rod 5 and the inner wall of the upper pump rod body 61 through the liquid introduction groove, and then enter the cavity of the upper pump rod body 61 at the upper part of the inner buckle 62 through the conductive notch 63. Since the delivery channel 54 and the conductive notch 63 are smaller than the general pump rod channel, the liquid has a greater pressure during the pumping process, so that the liquid can be output from the spray cover 12 more quickly, thereby forming a better atomization effect.

[0035] The external fastening portion 56 of the present invention comprises a cylindrical portion 561 disposed on the upper end of the lower pump rod body 51. The outer diameter of the cylindrical portion 561 is smaller than that of the lower pump rod body 51. A frustum-shaped guide portion 562 is provided at the upper end of the cylindrical portion 561. A fastening platform 563 is formed between the lower end surface of the frustum-shaped guide portion 562 and the upper end surface of the cylindrical portion 561. The internal fastening portion 62 comprises an inner boss 621, with a center hole corresponding to the outer diameter of the cylindrical portion 561 defined at its center. A guide tapered surface 622 is provided on the inner wall of the lower pump rod body 51 below the inner boss 621. In the present invention, the upper and lower pump rods engage each other through the external fastening portion 56 and the internal fastening portion 62, enhancing the pull-off force between the upper and lower pump rods. This effectively prevents accidental separation of the upper and lower pump rods during use, significantly improving the overall performance of the perfume pump.

[0036] The piston 7 of the present invention includes a center tube 71, within which is provided an inner convex ring 72 capable of forming a dynamic seal with the outer wall of the upper pump rod 6. A piston body 74 is provided at the lower end of the outer side of the inner convex ring 72 via a connecting platform 73. The outer wall of the lower end of the piston body 74 is dynamically sealed with the inner wall of the pump chamber 1. A positioning protrusion 64 is provided on the outer wall of the middle portion of the upper pump rod 6, and a limiting boss 65 is provided at the upper end of the positioning protrusion 64. A sleeve 66 capable of dynamically sealing with the positioning protrusion 64 is provided at the upper end of the outer side of the inner convex ring 72. The upper end of the upper spring 8 presses against the lower end surface of the positioning protrusion 64, and the lower end of the upper spring 8 presses against the upper end of the center tube 71. The monolinear fit between the outer wall of the lower end of the piston body 74 and the inner wall of the pump chamber 1 of the present invention effectively reduces friction between the piston and the inner wall of the pump chamber, thereby improving the pressing feel. The inner convex ring 72 in the center tube 71 of the present invention is linearly matched with the outer wall of the upper pump rod 6, which further reduces the friction between the piston and the outer wall of the upper pump rod 6, thereby making the pressing feel better.

[0037] The pump chamber 1 of the present invention includes a pump body 1001, a clamping ring 1002 is provided on the outer wall of the upper end of the pump body 1001, and a plurality of positioning ribs 1003 are spaced apart on the inner wall of the lower end of the pump body 1001. The pump ball chamber 3 is arranged on the inner side of the positioning rib 1003.

[0038] The grip-free bayonet 10 of the present invention includes a bayonet base 101, within which is a snap-fit ​​groove 102, into which a snap ring 1002 is secured. A connecting tube 103 is provided at the upper end of the bayonet base 101, capable of forming a dynamic seal with the outer wall of the piston 7. The pump chamber 1 and the grip-free bayonet 10 of the present invention cooperate with each other via the snap ring 1002 and the snap-fit ​​groove 102, allowing for quick connection and eliminating the gripping process. This makes assembly more convenient and quick, and also enhances the overall aesthetics of the product. In the present invention, a convex portion 111 is provided at the upper end of the outer cover 11, which matches the shape of the grab-free bayonet 10. An outer cover arc-shaped connecting portion 113 is provided between the convex portion 111 and the plane 112 at the top of the outer cover 11. The outer cover arc-shaped connecting portion 113 is pressed against the bayonet arc-shaped connecting portion 104 of the bayonet seat 101. In the present invention, a positioning groove 114 is provided in the outer cover 11, and the lower end of the bayonet seat 101 is clamped in the positioning groove 114. The upper end of the connecting tube 103 is pressed against the inner wall of the upper end of the convex portion 111, so that the grab-free bayonet 10 and the outer cover 11 are firmly connected.

[0039] The pump ball chamber 3 of the present invention includes an inner boss 31 disposed within the lower end of the pump body 1001. Within this boss 31 is a liquid delivery channel 32 connected to the liquid inlet pipe 2. Within this delivery channel 32 is a valve port 33. A plurality of elastic catches 34 are spaced above this valve port 33 to prevent the pump ball 4 from disengaging. The lower end of the lower spring 9 is sleeved onto the outer wall of the inner boss 31, and the upper end of the lower spring 9 presses against the lower end of the lower pump rod 5. The inner boss 31 effectively reduces the distance between the liquid outlet and the liquid inlet of the lower pump rod 5, significantly improving pumping efficiency and making the overall air pump faster. A second embodiment of the pump ball chamber 3 of the present invention, as shown in FIG1 , comprises a tapered valve port 33 disposed within the lower end of the pump body 1001. The pump ball 4 is movably disposed within this tapered valve port 33. A plurality of elastic catches 34 are spaced above this valve port 33 to prevent the pump ball 4 from disengaging.

[0040] The spray cap 12 of the present invention includes a cover body 121, a liquid guide channel 122 is provided in the cover body 121, a connecting seat 123 is provided in the middle of the cover body 121, a plug-in slot is provided in the connecting seat 123, the upper end of the upper pump rod 6 is plugged into the plug-in slot, a liquid spray channel 124 connected to the liquid guide channel 122 is provided on one side of the cover body 121, a center rod 125 is provided in the liquid spray channel 124, and a mist point 126 is sleeved on the outer end of the center rod 125. In the present invention, an aluminum cover 13 is provided on the outer cover of the spray cap 12, and the lower end of the aluminum cover 13 extends to the convex portion 111 of the outer cover 11, making the overall appearance more beautiful and making the product more high-end and classy.

[0041] In the present invention, a receiving groove 105 is provided on the inner wall of the lower end of the bayonet mount 101, and a sealing gasket 14 is provided on the outer wall of the pump chamber 1. The outer wall of the sealing gasket 14 is retained within the receiving groove 105. In the present invention, the sealing gasket 14 effectively improves the sealing between the pump chamber 1 and the perfume bottle, and between the grip-free bayonet mount 10 and the perfume bottle.

[0042] In the present invention, a liquid guide tube 15 is inserted into the liquid inlet tube 2 .

[0043] The present invention operates as follows: In the initial state, pump ball 4 seals the liquid inlet and inlet pipe 2, and spray cap 12 is in its highest position. Under the action of upper spring 8 and lower spring 9, the lower end of piston 7's central tube 71 seals against annular groove 53 of lower pump rod 5, thereby closing the liquid inlet end of delivery channel 54. When spray cap 12 is subjected to a downward external force, it drives upper and lower pump rods 6 and 5 downward. Simultaneously, piston 7 moves downward synchronously under the action of upper spring 8. When piston body 74 presses against the upper end of positioning rib 1003, piston 7 stops moving downward, compressing upper spring 8. At this point, upper and lower pump rods 6 and 5 continue to move downward, further compressing lower spring 9, and piston 7's central tube 71 separates from annular groove 53 of pump rod 5. The liquid inlet end of delivery channel 54 opens until the lower end of stop boss 65 contacts sleeve 66, halting downward movement of lower and upper pump rods 5 and 6. At this time, the air in the pump chamber 1 can be sent to the outside through the delivery channel 54 and the spray cover 12.

[0044] When the spray cover 12 loses external force, under the restoring action of the upper spring 8 and the lower spring 9, the lower pump rod 4 is driven to quickly form a seal with the piston 7, and then quickly move upward with the upper pump rod 6. At this time, negative pressure is formed in the pump chamber 1 below the piston 7, the pump ball 4 is opened, and the liquid enters the pump chamber from the liquid inlet pipe 2. When the spray cover 12 is pressed again, the pump ball 4 closes the liquid in the pump chamber 1 and is compressed, thereby being sprayed out along the delivery channel 54 and the spray cover 12.
