[0003] However, the vacuum pump in the above patent still has the following problems: 1. The floating outlet tube moves up and down, making it difficult for the paste outlet of the floating outlet tube to be aligned with the carrier (such as a toothbrush); 2. When pressing the floating outlet tube, it is necessary to overcome the elastic force of the vacuum pump reset spring, resulting in a large force required for pressing, which affects the user experience.

[0013] Furthermore, the transmission structure is a lever; the lever is mounted on the driven part, one end of the lever is in contact with and connected to the driving part, and the other end of the lever is in contact with and connected to the fulcrum part.

[0014] Furthermore, the shell comprises a lower shell, a middle shell and an upper shell which are sequentially snap-connected; the upper shell is provided with a paste outlet tube embedded in the floating tube, and the paste outlet tube is slidably matched with the floating tube.

[0015] Furthermore, the inner side wall of the floating tube is provided with a sealing protrusion which cooperates with the paste outlet tube.
