[0018] The technical solutions in the embodiments of the present application will be clearly described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present application. Embodiment

[0019] Refer to together Figures 1 - 4, the present utility model provides a lotion pump for a washing and care bottle, which includes an outer ring 1 for screwing onto the bottle mouth, a pump chamber 2, an inner sleeve 3, a pump tube 4, and a press head 5.

[0020] And this lotion pump can be applied to the washing and care bottle 6. The outer ring 1 is screwed onto the bottle mouth. The washing and care bottle 6 further includes a bottom tube 7 and a bottle buckle 8. The bottom tube 7 is inserted into the bottom of the pump chamber 2. The bottle buckle 8 is on the outside and buckled onto the washing and care bottle 6. The washing and care bottle 6 is filled with washing and care lotion.

[0021] In this embodiment, the outer ring 1, the pump chamber 2, the inner sleeve 3, and the pump tube 4 are all of a through structure. A pump liquid space with a variable volume is jointly formed between the pump tube 4, the inner sleeve 3, and the inside of the pump chamber 2. Among them, the pump tube 4 can be pressed. When pressed, the volume of the pump liquid space shrinks and the internal pressure increases, so that the lotion in the washing and care bottle 6 enters the pump liquid space.

[0022] The pump chamber 2 passes upward from the lower part of the outer ring 1 and is arranged inside the outer ring 1. The inner sleeve 3 is arranged on the outer ring 1 and penetrates into the inside of the pump chamber 2. The pump tube 4 penetrates into the inside of the inner sleeve 3 and can move up and down along its axis inside the inner sleeve 3. The press head 5 is inserted into the upper end of the pump tube 4, and a liquid outlet nozzle 50 is provided on the press head 5. The pump liquid space communicates with the liquid outlet nozzle 50. By pressing the press head 5, the pump liquid space is compressed and the lotion is pumped out through the liquid outlet nozzle 50. When the press head 5 is released, the press head 5 and the pump tube 4 move upward, releasing the pump liquid space, making the pump liquid space expand after being acted on and inhaling external air to prepare for the next pump of liquid.

[0023] A shoulder 20 is formed near the upper end of the pump chamber 2. An outer convex rib 21 is formed on the outer surface of the upper end of the pump chamber 2. The convex rib 21 is located above the shoulder 20. The convex rib 21 is an arc-shaped convex surface. In this solution, there are two convex ribs 21.

[0024] Correspondingly, a limiting platform 10 is formed on the inner edge of the upper end of the outer ring 1. The inner wall of the outer ring 1 is screwed onto the bottle mouth by threads. When the upper end of the pump chamber 2 passes out of the outer ring 1, the upper surface of the shoulder 20 fits against the lower surface of the limiting platform 10.

[0025] A groove 30 is formed on the inner wall at the upper end of the inner sleeve 3. The groove 30 matches the convex rib 21. When the inner sleeve 3 is inserted into the pump chamber 2, the convex rib 21 and the groove 30 are engaged in a snap-fit manner. The inner sleeve 3 is lapped on the upper surface of the limiting platform 10. During assembly, the upper end of the pump chamber 2 is directly passed through the outer ring 1, and then the pump chamber 2 and the outer ring 1 are pressed against each other to achieve quick insertion. The convex rib 21 and the groove 30 are positioned and matched. At this time, the inner sleeve 3 can rotate within a certain angular range. Moreover, threads are provided on both the outside of the pump tube 4 and the inside of the inner sleeve 3, so that the pump tube 4 can be screwed to the inner sleeve 3. When the pressing head 5 is pressed and then rotated, the pressing head 5 can be locked to the inner sleeve 3 as a whole. At this time, the pressing is locked and the emulsion cannot be pumped out, avoiding the pumping of the emulsion during transportation and facilitating carrying and transportation.

[0026] A plurality of first guiding ribs 31 extending axially are equally arranged circumferentially on the outside of the inner sleeve 3 near the upper end. A plurality of second guiding ribs 22 extending axially are equally arranged circumferentially on the inner wall at the upper end of the pump chamber 2. When the inner sleeve 3 is inserted into the pump chamber 2, the first guiding ribs 31 are limited between two adjacent second guiding ribs 22, so that the inner sleeve 3 can rotate within a certain range. Embodiment

[0027] An emulsion pump for a washing and care bottle includes an outer ring 1 for screwing onto the bottle mouth, a pump chamber 2, an inner sleeve 3, a pump tube 4, and a pressing head 5.

[0028] And this emulsion pump can be applied to the washing and care bottle 6. The outer ring 1 is screwed onto the bottle mouth. The washing and care bottle 6 further includes a bottom tube 7 and a bottle buckle 8. The bottom tube 7 is inserted into the bottom of the pump chamber 2. The bottle buckle 8 is on the outside of the appearance and buckled to the washing and care bottle 6. The washing and care bottle 6 is filled with washing and care emulsion.

[0029] In this embodiment, the outer ring 1, the pump chamber 2, the inner sleeve 3, and the pump tube 4 are all of a through structure. A pump liquid space with a variable volume is jointly formed among the pump tube 4, the inner sleeve 3, and the inside of the pump chamber 2. Among them, the pump tube 4 can be pressed. When pressed, the volume of the pump liquid space is reduced and the internal pressure becomes larger, so that the emulsion in the washing and care bottle 6 enters the pump liquid space.

[0030] The pump chamber 2 passes upward through the lower part of the outer ring 1 and is arranged inside the outer ring 1. The inner sleeve 3 is arranged on the outer ring 1 and penetrates into the inside of the pump chamber 2. The pump tube 4 penetrates into the inside of the inner sleeve 3 and can move up and down along its axis in the inner sleeve 3. The pressing head 5 is inserted into the upper end of the pump tube 4, and a liquid outlet nozzle 50 is provided on the pressing head 5. The pump liquid space communicates with the liquid outlet nozzle 50. By pressing the pressing head 5, the pump liquid space is compressed and the emulsion is pumped out through the liquid outlet nozzle 50. When the pressing head 5 is released, the pressing head 5 and the pump tube 4 move upward, releasing the pump liquid space, so that the pump liquid space becomes larger after being acted on and inhales external air to prepare for the next pumping of liquid.

[0031] A shoulder 20 is formed near the upper end of the pump chamber 2, and a rib 21 is formed on the outer surface of the upper end of the pump chamber 2. The rib 21 is located above the shoulder 20. The rib 21 is an arc-shaped raised surface. In this solution, there are two ribs 21.

[0032] Correspondingly, a limiting platform 10 is formed on the inner edge of the upper end of the outer ring 1. The inner wall of the outer ring 1 is screwed onto the bottle mouth. When the upper end of the pump chamber 2 passes out of the outer ring 1, the upper surface of the shoulder 20 abuts against the lower surface of the limiting platform 10.

[0033] A groove 30 is formed on the inner wall of the upper end of the inner sleeve 3. The groove 30 is matched with the rib 21. When the inner sleeve 3 and the pump chamber 2 are inserted into each other, they are clamped and matched through the rib 21 and the groove 30. The inner sleeve 3 is lapped on the upper surface of the limiting platform 10. During assembly, the upper end of the pump chamber 2 is directly passed through the outer ring 1, and then the pump chamber 2 and the outer ring 1 are pressed against each other to achieve quick insertion. The rib 21 and the groove 30 are positioned and matched. At this time, the inner sleeve 3 can rotate within a certain angle range. Moreover, threads are provided on both the outer part of the pump tube 4 and the inner part of the inner sleeve 3, so that the pump tube 4 can be screwed onto the inner sleeve 3. When the press head 5 is pressed and then rotated, the press head 5 can be locked with the inner sleeve 3 as a whole. At this time, the pressing is locked and the emulsion cannot be pumped out, avoiding the pumping of the emulsion during transportation and facilitating carrying and transportation.

[0034] A plurality of first guiding ribs 31 extending axially are evenly arranged circumferentially on the outer part of the inner sleeve 3 near the upper end. A plurality of second guiding ribs 22 extending axially are evenly arranged circumferentially on the inner wall of the upper end of the pump chamber 2. When the inner sleeve 3 and the pump chamber 2 are inserted into each other, the first guiding ribs 31 are limited between two adjacent second guiding ribs 22, so that the inner sleeve 3 can rotate within a certain range.

[0035] In this embodiment, the emulsion pump further includes a top cover 11. The top cover 11 is penetrated by the pump tube 4 and buckled on the limiting platform 10. A gasket 9 is also sleeved on the shoulder 20. The gasket 9 is hermetically arranged between the lower surface of the shoulder 20 and the inside of the inner sleeve 3, so as to improve the sealing performance between the emulsion pump and the washing and care bottle 6.

[0036] When this emulsion pump is installed on the bottle mouth of the washing and care bottle 6, a pumping liquid space is jointly formed among the pump chamber 2, the inner sleeve 3 and the inside of the pump tube 4. And the pumping liquid space can have different internal pressure space sizes due to the lifting movement of the pump tube 4. When the press head 5 is pressed, the pump tube 4 gradually moves downward, the pumping liquid space gradually becomes smaller, and the internal pressure becomes larger, so that the emulsion in the washing and care bottle 6 is pressed out of the liquid outlet nozzle 50 through the pumping liquid space, realizing the quick pumping of the emulsion in a practical way and being convenient to operate.
