[0026] Beneficial effects

[0027] The rotary emulsion pump provided in the embodiments of the present invention has a sliding groove on the inner shell.

[0034] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0035] See also Figure 1 As shown, according to an embodiment of this application, a rotary emulsion pump is provided, the emulsion pump being connected to a bottle, the emulsion pump comprising:

[0036] Pump cover 1, which is connected to the bottle body;

[0037] Pump housing assembly 2, which is connected to the pump cover 1;

[0038] Extraction component 3 is disposed inside the pump housing assembly 2. The bottom of the extraction component 3 is provided with a multi-branch suction tube 4, which is located inside the bottle body.

[0039] The pressure head 5 has a liquid outlet channel inside. The pressure head 5 passes through the pump cover 1 and is connected to the extraction component 3. When the pressure head 5 is pressed, the pressure head 5 can drive the extraction component 3 to rotate inside the pump housing assembly 2, so that the multi-branch suction tube 4 can rotate and adsorb the liquid in the bottle.

[0040] Specifically, the emulsion pump is installed on the bottle body to extract the liquid from the bottle for use. The emulsion pump includes a pump cover 1, a pump housing assembly 2, an extraction assembly 3, a multi-branch suction tube 4, and a pressure head 5. The pump cover 1 has threads that can be threaded to the bottle body, making it easy to fix the emulsion pump on the bottle body. When the pump cover 1 is installed on the bottle body, the pump housing assembly 2, the extraction assembly 3, and the multi-branch suction tube 4 are all located inside the bottle body. The pressure head 5 is located on top of the pump cover 1, and the user can extract the liquid from the bottle body by compressing the pressure head 5.

[0041] When the user presses down on the pump head 5, the pump head 5 drives the extraction component 3 to move up and down inside the pump housing assembly 2, drawing liquid from the bottle through the multi-branch suction tube 4. The drawn liquid enters the extraction component 3 and is discharged through the pump head 5 for the user's use. While the pump head 5 drives the extraction component 3 to move up and down, the extraction component 3 can also rotate inside the housing assembly 2, thereby driving the multi-branch suction tube 4 to rotate and draw liquid from inside the bottle. The rotational movement expands the actual adsorption range of the multi-branch suction tube 4, improves coverage of the residual area at the bottom of the bottle, improves the extraction efficiency, effectively reduces the amount of liquid remaining inside the bottle, increases product usage, saves energy, and reduces costs.

[0042] The pump housing assembly 2 includes:

[0043] The outer casing 21 is connected to the pump cover 1;

[0044] The inner housing 22 is disposed inside the outer housing 21, and the inner housing 22 is provided with a sliding groove 23.

[0045] The chute 23 includes a first inclined chute 231, a first vertical chute 232, a second inclined chute, and a second vertical chute connected in sequence. The bottom of the first inclined chute 231 is connected to the bottom of the first vertical chute 232, the top of the first vertical chute 232 is connected to the top of the second inclined chute, the bottom of the second inclined chute is connected to the bottom of the second vertical chute, and the top of the second vertical chute is connected to the bottom of the first inclined chute 231.

[0046] Specifically, the pump housing assembly 2 includes an outer shell 21 and an inner shell 22. The outer shell 21 is a tubular structure, and its top is fixedly connected to the pump cover 1. The inner shell 22 is installed inside the outer shell 21 and is fixedly connected to the outer shell 21. A sliding groove 23 is provided on the inner shell 22. The sliding groove 23 includes a first inclined groove 231, a first vertical groove 232, a second inclined groove, and a second vertical groove. The sliding groove 23 is used to limit and fix the extraction component 3. When the pressure head 5 is pressed, the extraction component 3 can move up and down and rotate along the path of the first inclined groove 231, the first vertical groove 232, the second inclined groove, and the second vertical groove. This allows the liquid inside the bottle to be extracted while the extraction component 3 and the multi-branch suction tube 4 can rotate inside the bottle, improving the coverage of the residual area at the bottom of the bottle by the multi-branch suction tube 4, improving the extraction efficiency, effectively reducing the residual liquid inside the bottle, increasing product usage, saving energy, and reducing costs.

[0047] The extraction component 3 includes:

[0048] Pressure plate 31, which is disposed inside the inner housing 22 and is connected to the pressure head 5;

[0049] The extraction tube 32 is disposed inside the inner shell 22 and located below the pressure plate 31. A pin 33 is provided on the outer circumference of the extraction tube 32, and the pin 33 is located in the sliding groove 23.

[0050] The first elastic element 34 is disposed between the pressure plate 31 and the top of the extraction tube 32;

[0051] A spherical cover 35 is connected to the bottom of the extraction tube 32. A storage cavity is formed inside the spherical cover 35. A first through hole and a second through hole are formed in the spherical cover 35 along the axial direction of the extraction tube 32. A multi-branch suction tube 4 is disposed on the spherical cover 35. The interior of the multi-branch suction tube 4 is connected to the storage cavity.

[0052] A first pressure ball 36 is disposed inside the storage cavity, and the diameter of the first pressure ball 36 is larger than the diameter of the first through hole;

[0053] A retaining ring 37 is disposed inside the inner housing 22, and a second elastic element 38 is disposed between the pressure plate 31 and the retaining ring 37.

[0054] The first elastic element 34 and the second elastic element 38 are springs.

[0055] It also includes a second pressure ball 7, and a limiting ring 6 is symmetrically arranged in the liquid outlet channel inside the pressure head 5, and the second pressure ball 7 is disposed on the limiting ring 6.

[0056] The limiting ring 6 has a conical hole inside, and the diameter of the second pressure ball 7 is larger than the diameter of the conical hole.

[0057] Specifically, the extraction assembly 3 includes a pressure plate 31, an extraction tube 32, a first elastic element 34, a ball cover 35, a first pressure ball 36, a fixing ring 37, a second pressure ball 7, and a limiting ring 6. The pressure plate 31 is a tubular structure with a bottom seal. Its bottom sealed end is fixedly connected to the pressure head 5, and a connection hole is provided at the matching position with the liquid outlet channel. When the user presses the pressure head 5, the pressure plate 31 moves downward synchronously when the pressure head 5 is pressed down. The first pressure plate 31 will drive the first elastic element 34 and the second elastic element 38 to compress. The elastic element 34 transmits external force to the extraction tube 32. The pin 33 on the outer circumference of the extraction tube 32 is located in the groove 23 of the inner housing 22. The groove 23 provides axial guidance for the pin 33. At this time, the pin 33 will gradually slide from the top to the bottom of the first inclined groove 231. Simultaneously, during this process, the gas in the pressure plate 31 and the extraction tube 32 will gradually decrease. The first pressure ball 36 is pressed against the second through hole of the ball cover 35, sealing from the bottom of the ball cover 35. The second pressure ball 7 will be at the limiting ring. The pressure plate 31 moves upward, causing the gas between the pressure plate 31 and the extraction tube 32 to be discharged from the conical hole of the limiting ring 6. At this time, the gas volume inside the pressure plate 31 and the extraction tube 32 is at its minimum. When the pressure head 5 is released, under the elastic potential energy of the second elastic element 38, the pressure head 5 will return to its initial height. At this time, the pin 33 will move from the bottom of the first inclined groove 231 to the top of the first vertical groove 232. Simultaneously, during this process, the second pressure ball 7 will be tightly attached to the limiting ring 6, thereby sealing the conical hole of the limiting ring 6. When the first pressure ball 36 disengages from the second through hole, the multi-branch suction tube 4 can then draw the liquid from the bottle into the space between the extraction tube 32 and the pressure plate 31. During further pressing by the user, the pin 33 repeatedly moves from the top of the second inclined groove to the bottom of the second vertical groove. Releasing the pressure head 5, the pin 33 moves from the bottom of the second vertical groove to the top. As the user continues to press, the pin 33 repeats the above steps, creating a cycle of extraction until the liquid is discharged from the outlet channel of the pressure head 5. As the pin 33 continuously moves through the first inclined groove 231, the first vertical groove 232, the second inclined groove, and the second vertical groove, it continuously drives the multi-branch suction tube 4 to draw the liquid from the bottle into the inner shell 22, which can then be discharged through the outlet channel of the pressure head 5 for the user's use. Furthermore, this process also causes the multi-branch suction tube 4 to rotate and draw liquid, increasing the range of liquid extraction from the bottle.

[0058] The first and second through holes of the spherical cover 35 along the axis form a liquid passage. The second through hole is located below the first through hole. The first pressure ball 36 is disposed in the storage cavity and its diameter is larger than that of the first through hole. When the extraction tube 32 moves down, the pressure change inside the storage cavity pushes the first pressure ball 36 to seal the second through hole. When the extraction tube 32 is reset, the first pressure ball 36 disengages from the second through hole and is located in the storage cavity. Several protrusions are installed below the first through hole of the storage cavity to prevent the first pressure ball 36 from blocking the first through hole, so that the liquid can enter the inner shell 22.

[0059] The downward movement of the pressure plate 31 pushes the extraction tube 32 to descend synchronously through the first elastic element 34. The pin 33 on the outer circumference of the extraction tube 32 is embedded in the groove 23 of the outer shell 21. Under the action of the groove 23, the extraction tube 32 rotates as it descends axially, driving the bottom ball cover 35 and the multi-branch straw 4 to rotate synchronously, ensuring that the multi-branch straw 4 maintains a stable rotation trajectory during the pressing process and sweeps over the residue area at the bottom of the bottle.

[0060] The limiting ring 6 is installed inside the liquid outlet channel and has a conical hole inside. It is used to limit and fix the second pressure ball 7. When the pressure head 5 moves downward, the air pressure inside the inner shell 22 is released. During this process, the first pressure ball 36 presses against the second through hole of the ball cover 35, achieving a seal. The second pressure ball 7 is located above the limiting ring 6. Therefore, the gas inside the inner shell 22 pushes the second pressure ball 7 upward, thus allowing the gas inside the inner shell 22 to be released. During the process of the second elastic element 38 driving the pressure head 5 back to its initial height, the second pressure ball 7, under its own weight, seals the conical hole on the limiting ring 6. Meanwhile, the inner shell 22 moves the first pressure ball 36 upward, disengaging it from the second through hole, allowing the liquid inside the bottle to be absorbed into the inner shell 22, thus achieving liquid extraction.

[0061] The second pressure ball 7 is provided with a stop bar 8 at its top.

[0062] Specifically, the stop lever 8 is installed on the second pressure ball 7 and is located on the side of the second pressure ball 7 away from the limit ring 6. By setting the stop lever 8, the second pressure ball 7 can be prevented from being discharged from the liquid outlet channel, thereby improving the sealing performance and service life of the emulsion pump.

[0063] The multi-branch suction tube 4 includes a first tube body 41, a first branch tube 42, and a second branch tube 43, with the first branch tube 42 and the second branch tube 43 arranged inclined downward on both sides of the first tube body 41.

[0064] Specifically, the multi-branch straw 4 includes a first tube body 41, a first branch tube 42, and a second branch tube 43. The first tube body 41 is connected to the storage cavity of the bulb shroud 35, while the first branch tube 42 and the second branch tube 43 are inclined downwards on both sides of the first tube body 41. This design expands the coverage area for liquid extraction. In actual extraction, liquid is often distributed in different locations or areas, and a single straw cannot completely and quickly extract all the liquid. By having the first branch tube 42 and the second branch tube 43 inclined downwards on both sides of the first tube body 41, their absorption ends can be closer to the edge area of ​​the liquid distribution in the bottle, thereby more effectively capturing liquid from different locations and reducing liquid residue.

[0065] The angle between the first branch pipe 42 and the second branch pipe 43 is less than 45 degrees, which can expand the extraction range and effectively improve the efficiency of liquid extraction when the extraction component 3 drives the multi-branch suction pipe 4 to rotate and extract liquid.

[0066] The angle between the first branch pipe 42 and the first pipe body 41 and the angle between the second branch pipe 43 and the first pipe body 41 can be set according to the usage requirements. The angle between the first branch pipe 42 and the first pipe body 41 and the angle between the second branch pipe 43 and the first pipe body 41 can be the same or different.

[0067] A sealing ring is provided between the fixing ring 37 and the extraction tube 32.

[0068] Specifically, the sealing ring is installed between the fixed ring 37 and the extraction tube 32 to improve the sealing performance between the fixed ring 37 and the extraction tube 32.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
