[0023] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] As Figures 1 to 4 shown, this embodiment provides a new type of pressing pump head, including a pump head body 1, a connecting cover 2 and a pressing cover 3. By pressing the pressing cover 3 by hand, the pressing cover 3 applies pressure to the pump head body 1, and the pump head body 1 is used to draw out the liquid. The connecting cover 2 is of a disc-shaped structure. After the pressing cover 3 is pressed down, it enters the disc-shaped structure. The pump head body 1 is fixed at the axial center position inside the connecting cover 2, and the pressing cover 3 is fixed at the top position of the pump head body 1. A first liquid outlet channel 31 is arranged at the axial center position of the pressing cover 3 and extends outward to communicate with the inside of the pump head body 1. An extension tube 32 is inserted into the first liquid outlet channel 31. A liquid outlet 321 is arranged at a position near the end of the extension tube 32 and at the bottom. By inserting the extension tube 32 into the first liquid outlet channel 31 and the liquid outlet 321 being located at the downward position of the extension tube 32, it is possible to avoid excessive pressing force, causing the liquid to spray to a far place and resulting in waste. This structure is simple.

[0025] Preferably, the extension tube 32 is made of a metal material. The metal material itself has a certain degree of hardness and will not deform when inserted into the first liquid outlet channel 31.

[0026] Preferably, the connecting cover 2 is connected to the bottle body 4. A rubber ring 21 is arranged between the connecting cover 2 and the bottle body 4. A sealing strip 211 is arranged at the position where the rubber ring 21 contacts the bottle body 4. The sealing strip 211 on the rubber ring 21 can improve the sealing performance.

[0027] Preferably, a metal cover is covered on the pressing cover 3, which can improve the aesthetics.

[0028] Preferably, the pump head body 1 includes an outer sleeve 11, a pressing rod 12, a spring 13 and a ball 14. The upper part of the outer sleeve 11 has a wider diameter and the lower part has a narrower diameter. A limiting ring 111 is arranged inside the outer sleeve 11. The ball 14 is arranged on the limiting ring 111 of the outer sleeve 11. The ball 14 is used to block the limiting ring to prevent the liquid from flowing downward in the outer sleeve 11. The spring 13 is arranged inside the outer sleeve 11 and presses against the ball 14. The spring 13 can support the pressing rod 12 to return to its original position. The pressing rod 12 is arranged inside the outer sleeve 11 and moves up and down while sleeving the spring 13.

[0029] Preferably, the pressing rod 12 includes an upper pressing rod 122 and a lower pressing rod 123. The upper pressing rod 122 penetrates up and down. An upper through pipe 124 is provided on the lower pressing rod 123. The upper through pipe 124 is inserted into the bottom of the upper pressing rod 122. A liquid inlet 125 is provided on the upper through pipe 124. A sealing ring 121 is provided between the upper pressing rod 122 and the lower pressing rod 123 around the upper through pipe 124. When the pressing rod 12 is pressed down, the sealing ring 121 can form a sealed space in the outer sleeve 11. When the pressing rod 12 moves upward, liquid can be drawn into the outer sleeve 11. The sealing ring 121 moves up and down between the upper pressing rod 122 and the lower pressing rod 123 to open or close the liquid inlet 125. When pressing down continuously, the liquid in the outer sleeve 11 can enter the upper pressing rod 122 from the liquid inlet 125 and be discharged from the first liquid outlet channel 31 of the pressing cover 3.

[0030] Preferably, a locking cover 15 is covered on the top of the outer sleeve 11. The top of the pressing rod 12 extends out of the locking cover 15. The locking cover 15 is used to prevent the pressing rod 12 from popping out and locks the pressing rod 12 to move up and down in the outer sleeve 11.

[0031] Preferably, a rim 112 is provided on the periphery of the outer sleeve 11. A tooth cover 16 is provided between the locking cover 15 and the rim 112. A step 22 is provided in the middle of the connecting cover 2. The tooth cover 16 covers the step 22, and the step 22 is located between the tooth cover 16 and the rim 112. The tooth cover 16 is used to fix the pump head body 1, and the step 22 is used to be better covered by the tooth cover 16.

[0032] In the prior art during use, it is easy to apply too much pressing force, causing the liquid to spray to a far place, resulting in waste. Therefore, a new type of pressing pump head is provided. A first liquid outlet channel 31 is arranged from the axial center position of the pressing cover 3 to the periphery direction. The extension pipe 32 is inserted into the first liquid outlet channel 31, and the liquid outlet 321 is located at the downward position of the extension pipe 32, which can avoid applying too much pressing force easily, causing the liquid to spray to a far place and resulting in waste. This way has a simple structure.
