DETAILED DESCRIPTION

[0019] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0020] Reference below Figures 1 to 4 A lotion pump with a water-proof function according to an embodiment of the present invention is described, comprising a pressure head 1, a cap 3 and a pump body 4, which are connected in sequence. The pressure head 1 is connected to a push tube 9, one end of which passes through the cap 3 and one end of which is placed in the pump body 4. An elastic member 7 is provided in the pump body 4, which is sleeved on the push tube 9. A piston head 6 is provided at the lower end of the push tube 9. A sealing cover 8 is provided at the top opening of the cap 3. The top surface of the sealing cover 8 is provided with an inclined surface 801, and a top convex ring 802 is provided in the middle of the inclined surface 801. A flow guide tube 101 is provided in the pressure head 1, which passes through the middle of the top convex ring 802, and the push tube 9 is connected to the flow guide tube 101.

[0021] This structure features a sloped surface 801 on the top surface of the sealing cap 8, with a raised ring 802 positioned in the middle of the sloped surface 801. This allows water to flow outward from the sloped surface 801, effectively draining the water. Furthermore, the raised ring 802 is higher than the sloped surface 801, further increasing its height and accelerating the flow of water toward the sloped surface 801. This prevents water from entering the lotion pump through the gap and contaminating the lotion.

[0022] In addition, the pressure head 1 and the flow guide tube 101 are integrally formed. The other end of the flow guide tube 101 extends to the outlet of the pressure head 1. The cap 3 is mounted on the pump body 4 and is screwed together with the lotion bottle. The pump body 4 is placed in the lotion bottle. The elastic member 7 is used to push the push tube 9 to reset. The top of the push tube 9 has a boss. The boss presses against the top of the elastic member 7 in the squeeze state, and the elastic member 7 is compressed. When the pressure head 1 is released, the elastic member 7 pushes the boss on the top of the push tube 9, causing the push tube 9 to return to its original position and wait for the next squeeze. Furthermore, the top of the piston head 6 is placed in the push tube 9 and connected. The piston head 6 moves up and down, creating a negative pressure in the pump body 4, sucking in the lotion and the emulsion in it, entering the push tube 9 and then being discharged from the flow guide tube 101 of the pressure head 1.

[0023] In this structure, the outer edge of the inclined surface 801 extends to the outer edge of the cap 3 , so that water flows out of the cap 3 .

[0024] The lower end of the sealing cover 8 of this structure extends to the inner wall of the cap 3, and the sealing cover 8 is fastened to the cap 3. A recess 803 is provided on the lower end surface of the sealing cover 8, and a convex ring 301 is provided on the inner wall of the cap 3. The convex ring 301 is placed in the recess 803 to further seal the seal and prevent water from seeping in through the gap.

[0025] The cap 3 of this structure is provided with a positioning member 2, and the pressure head 1 is located above the positioning member 2. The positioning member 2 prevents the pressure head 1 from moving downward, thereby preventing the floating liquid from being discharged from the pressure head 1 and causing a waste of the floating liquid.

[0026] The pump body 4 of this structure is provided with a catch 401, and a bead 402 is provided in the catch 401. The catch 401 is distributed in an annular shape and is used to limit the space for the bead 402 to move up and down. When the bead 401 moves down, it can block the space and prevent the lotion from flowing back into the lotion bottle.

[0027] In this structure, a tube 5 is inserted into the lower end of the pump body 4. The tube 5 acts as an extension and is close to the bottom surface of the lotion bottle. This allows the lotion to quickly flow from the tube 5 into the lower end of the pump body 4 and into the push tube 9 during the suction process. A space is provided at the lower end of the pump body 4 for the tube 5 to be inserted. The tube 5 and the space in the pump body 4 are tightly connected to each other, thereby securing the tube 5.

[0028] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
