After the inner tube is connected to the pressing part, the column tube is located between the inner tube and the outer tube, and a gap is left between the outer tube and the column tube. The connecting tube is made of plastic.

[0007] Furthermore, a pressing plate is provided on the top of the pressing head, and the area of ​​the pressing plate is larger than the cross-sectional area of ​​the pressing head.

[0008] Furthermore, the liquid outlet pipe extends into the interior of the connecting pipe.

[0009] Furthermore, the pump body structure includes an outer sleeve, a spring, and a ball bearing. The outer sleeve has a wider upper diameter and a narrower lower diameter. A limiting ring is provided inside the outer sleeve. The ball bearing is disposed on the limiting ring of the outer sleeve. The spring is disposed inside the outer sleeve and presses against the ball bearing. The pressing part is disposed inside the outer sleeve and fits around the spring to move up and down.

[0010] Furthermore, the pressing part includes an upper pressing rod and a lower pressing rod. The upper pressing rod extends vertically through the lower pressing rod, and an upper through-tube is provided on the lower pressing rod. The upper through-tube is inserted into the bottom of the upper pressing rod, and an inlet is provided on the upper through-tube. A sealing ring is provided around the upper through-tube and between the upper and lower pressing rods.

[0022] like Figures 1 to 4As shown, this embodiment provides a push-button pump head, including a pump body structure 1, a housing 2, and a push-button head 3. A column tube 21 is provided on the housing 2, with a through structure extending into the housing 2. The housing 2 covers the pump body structure 1. The housing 2 is entirely made of metal. A pressing part 11 is provided on the pump body structure 1, located inside the column tube 21. A liquid outlet pipe 31 is provided on the push-button head 3. A connecting pipe 4 is provided inside the push-button head 3. The connecting pipe 4 includes an outer pipe 41 and an inner pipe 42. The top of the outer pipe 41 is connected and fixed to the top of the inner pipe 42. 42 is fixedly connected to the pressing part 11. The outer tube 41 is fitted to the inner wall of the pressing head 3. After the inner tube 42 is connected to the pressing part 11, the column tube 21 is located between the inner tube 42 and the outer tube 41, and there is a gap between the outer tube 41 and the column tube 21. The connecting tube 4 is made of plastic. The metal surfaces of the pressing part 11, the outer shell 2 and the column tube 21 are coated with color. When the pressing head 3 presses, when the outer tube 41 of the connecting tube 4 comes into contact with the column tube 21, the plastic material of the connecting tube 4 will not rub against the column tube 21, thus avoiding scratching off the color on the column tube 21 and maintaining its aesthetics.

[0023] As an optional embodiment, the top of the pressing head 3 is provided with a pressing plate 32, the area of ​​which is larger than the cross-sectional area of ​​the pressing head 3, and the pressing plate 32 can increase the pressing feel.

[0024] As an optional embodiment, the liquid outlet pipe 31 extends into the interior of the connecting pipe 4, and liquid is discharged from the connecting pipe 4 into the liquid outlet pipe 31.

[0025] As an optional embodiment, the pump body structure 1 includes an outer tube 12, a spring 13, and a ball bearing 14. The outer tube 12 has a wider upper diameter and a narrower lower diameter. A limiting ring 121 is provided inside the outer tube 12. The ball bearing 14 is disposed on the limiting ring 121 of the outer tube 12. The ball bearing 14 is used to block the limiting ring 121 to prevent liquid from flowing down the outer tube 12. The spring 13 is disposed inside the outer tube 12 and presses against the ball bearing 14. The spring 13 can support the pressing part 11 so that it can return to its original position. The pressing part 11 is disposed inside the outer tube 12 and fits around the spring 13 to move up and down.

[0026] As an optional embodiment, the pressing part 11 includes an upper pressing rod 111 and a lower pressing rod 112. The upper pressing rod 111 extends vertically, and the lower pressing rod 112 is provided with an upper through pipe 113. The upper through pipe 113 is inserted into the bottom of the upper pressing rod 111, and the upper through pipe 113 is provided with a liquid inlet 114. A sealing ring 15 is provided around the upper through pipe 113 and between the upper pressing rod 111 and the lower pressing rod 112. When the pressing part 11 is pressed, the sealing ring 15 can form a sealed space inside the outer tube 12. When the pressing part 11 moves upward, liquid can be drawn into the outer tube 12. The sealing ring 15 moves up and down between the upper pressing rod 111 and the lower pressing rod 112, thereby opening or closing the liquid inlet 114. When the pressing part continues to be pressed, the liquid in the outer tube 12 can enter the upper pressing rod 111 from the liquid inlet 114 and be discharged from the liquid outlet pipe 31 of the pressing head 3.

[0027] As an optional embodiment, a locking cap 16 is provided at the top of the outer tube 12, and the top of the pressing part 11 extends out of the locking cap 16. The locking cap 16 is used to prevent the pressing part 11 from popping out and to lock the pressing part 11 to move up and down inside the outer tube 12. An edge 122 is provided on the periphery of the outer tube 12, and a threaded cap 17 is provided between the locking cap 16 and the edge 122. The threaded cap 17 is used to thread the bottle.

[0028] In existing technology, the upper cylindrical part of the metal casing and the cylindrical part under the metal pressing head are prone to contact and friction, which can scratch off the surface color layer and affect the aesthetics. This is addressed by providing a pressing pump head, wherein the pressing head 3 is provided with a connecting pipe 4, the connecting pipe 4 including an outer pipe 41 and an inner pipe 42. The top of the outer pipe 41 is fixedly connected to the inner pipe 42, the inner pipe 42 is fixedly connected to the pressing part 11, and the outer pipe 41 is fitted to the inner wall of the pressing head 11. After the process of connecting with the pressing part 11, the column tube 21 is located between the inner tube 42 and the outer tube 41, and there is a gap between the outer tube 41 and the column tube 21. The connecting tube 4 is made of plastic. The metal surfaces of the pressing part 11, the outer shell 2 and the column tube 21 are coated with color. When the pressing head 3 presses, when the outer tube 41 of the connecting tube 4 comes into contact with the column tube 21, because the connecting tube 4 is made of plastic, it will not rub against the column tube 21. This can avoid scratching off the color on the column tube 21 and maintain its appearance.

[0029] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
