[0026] This section will describe the specific embodiments of the present application in detail. The preferred embodiments of the present application are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present application, but it cannot be understood as a limitation on the scope of protection of the present application.

[0027] In the description of this application, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0028] In the description of this application, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0029] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0030] Referring to Figures 1 to 12, a stable foaming extrusion foam pump includes a connecting cap 10, a delivery assembly 20, a foaming assembly 30, and a pump head 40. The connecting cap 10 is mounted on the mouth of a container. The delivery assembly 20 is mounted on the connecting cap 10. The delivery assembly 20 is used to deliver liquid. The delivery assembly 20 and the connecting cap 10 cooperate to form the foaming assembly 30. The foaming assembly 30 is used to convert liquid into foam. The pump head 40 is mounted on the connecting cap 10 and is in communication with the foaming assembly 30.

[0031] It is worth noting that by squeezing the container bottle, the liquid in the bottle rises along the conveying component 20 to the foaming component 30, and the foaming component 30 can mix the liquid with air to foam, and then deliver it through the pump head 40. This realizes extrusion foaming.

[0032] 2 and 6 , the delivery assembly 20 includes a delivery tube 21 and a backflow prevention bead 22. The upper end of the delivery tube 21 is connected to the connection cap 10. The backflow prevention bead 22 is movably disposed at the lower portion of the delivery tube 21. The backflow prevention bead 22 is used to prevent the liquid from flowing back into the container bottle.

[0033] Referring to Figures 2 to 12 , the foaming assembly 30 includes a foaming plug 31 and a foam thinning plug 32. The foaming plug 31 is inserted into the delivery tube 21 and is used to mix gas and liquid for foaming. The foam thinning plug 32 is disposed within the delivery tube 21 and positioned above the foaming plug 31. The delivery tube 21 is provided with an air inlet 33, located adjacent to the foaming plug 31.

[0034] It is worth noting that in the embodiment of the present application, the air inlet 33 is opened next to the foaming plug 31, and the air inlet path is short, so that sufficient air can be obtained for foaming with just one squeeze. After squeezing once, the water density of the bubbles will be normal, greatly improving the user experience.

[0035] Referring to Figures 2 to 7 , the foaming plug 31 includes a first column 311, a first annular groove 312, and a second annular groove 313. A gap is left between the first column 311 and the delivery tube 21. The first annular groove 312 and the second annular groove 313 are connected through a plurality of connecting holes 314. The delivery tube 21 is provided with a plurality of connecting grooves 315. The air inlet 33 is connected to the first annular groove 312 through the connecting grooves 315.

[0036] It is understandable that air can enter the foaming plug 31 along the connecting groove 315 through the air inlet 33 and enter the first annular groove 312 together with the liquid, and foam will be generated in this process.

[0037] 11 and 12 , the foam thinning plug 32 includes a plug body 321 and a thinning net 322 . The plug body 321 is hollow. The thinning net 322 is provided at both ends of the plug body 321 .

[0038] It is worth mentioning that the foamed foam can be further refined by the refinement net 322 to produce dense foam, thereby improving the user experience.

[0039] 2 to 12 , a stable foaming squeeze foam pump further includes an air pressure balancing assembly 50. The air pressure balancing assembly 50 includes an upper half groove 51, a lower half groove 52, and a movable sealing bead 53. The upper half groove 51 is disposed on the connecting cover 10. The lower half groove 52 is disposed on the delivery pipe 21. The upper half groove 51 and the lower half groove 52 are plugged into each other. A first balancing air passage 511 is defined in the upper half groove 51. The movable sealing bead 53 is movably disposed in the first balancing air passage 511. The movable sealing bead 53 can block the first balancing air passage 511. The lower half groove 52 is provided with a second balancing air passage 521 connected to the container bottle. A blocking slope 511a is symmetrically provided at the lower end of the first balancing air passage 511. The blocking slope 511a is used to prevent the movable sealing bead 53 from blocking the lower end of the first balancing air passage 511.

[0040] It is worth noting that when the container bottle is squeezed, the movable sealing bead 53 presses against the upper end of the first balancing air channel 511, and the pressure in the bottle is converted into the power to pump out the liquid and generate foam. When the container bottle is released, the movable sealing bead 53 falls back, the first balancing air channel 511 opens, and external air enters the container bottle through the second balancing air channel 521.

[0041] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
