[0037] In the description of the present application, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present application after combining with the specific content of the technical solution.

[0038] Refer to Figures 1 to 4, the bubble outlet component of the first aspect embodiment of the present application includes a housing assembly 100. The housing assembly 100 forms a bubble outlet channel 200; a foam inlet 210 is formed at the inner end of the bubble outlet channel 200; a bubble outlet 220 is formed at the outer end of the bubble outlet channel 200, and the bubble outlet 220 is located on one side surface of the housing assembly 100; the cross-sectional dimension of the bubble outlet channel 200 gradually decreases along the direction from the bubble outlet 220 to the foam inlet 210, and the bubble outlet channel 200 gradually extends along the direction from the top surface to the bottom surface of the housing assembly 100. It can be understood that through targeted design of the structure of the bubble outlet channel 200, the bubble outlet channel 200 is designed to have a structure with a larger outer part and a smaller inner part in terms of structural size design, which can not only avoid the problems of poor foam shape and unstable abnormal accumulation ejected from a narrow channel, but also enable the foam to have a certain sense of release when ejected, improving the user experience; in terms of the internal channel structure design, the bubble outlet channel 200 is designed to have a structure with a higher outer part and a lower inner part, creating a height difference between the foam inlet position and the bubble outlet position, causing the foam remaining at the bubble outlet or the liquefied foam to flow back, avoiding the occurrence of foam hanging and residual liquid dripping at the bubble outlet, and reducing the phenomenon of residual liquid remaining on the bottle body.

[0039] In some embodiments, the direction from the top surface to the bottom surface of the housing assembly 100 is also the height direction or the gravity direction. By adopting the design of a higher outer part and a lower inner part, the internal and external height difference of the bubble outlet channel 200 is relatively large, thereby avoiding the residue of foam / liquid at the product bubble outlet.

[0040] In some embodiments of the present application, the inner diameter of the bubble outlet 220 is a, and the inner diameter of the foam inlet 210 is b. The relationship between a and b satisfies the following: a:b > 2:1. It can be understood that by specifically defining the dimensional relationship between the bubble outlet 220 and the foam inlet 210, the quality of the output foam can be controlled, ensuring the stability of the foam shape while further enhancing the volume sense of the foam.

[0041] It should be noted that in the bubble outlet channel 200 of the related art spray bubble device, the width of the inner and outer channels is the same and uniform or the dimensional difference is small, resulting in too fast foam ejection speed, poor foam shape and unstable accumulation. The bubble outlet channel 200 of the present application adopts a flared shape with a larger outer part and a smaller inner part, thereby avoiding the problems of poor foam shape and unstable abnormal accumulation ejected from a narrow channel, and at the same time enabling the foam to have a certain sense of release when ejected, improving the user experience.

[0042] In some embodiments, according to different usage scenarios or requirements, the inner diameter of at least one of the bubble outlet 220 or the foam inlet 210 can be adaptively adjusted to improve the texture and volume sense of the foam.

[0043] In some embodiments of the present application, the foam outlet channel 200 includes a bottom inner wall 201, a top inner wall 202, and a side inner wall 203 disposed between the bottom inner wall 201 and the top inner wall 202. The bottom inner wall 201 is arranged as a convex arc surface towards the top inner wall 202, the top inner wall 202 is arranged as a concave arc surface along the direction away from the bottom inner wall 201, and the side inner wall 203 is arranged as a smooth arc surface and connects the bottom inner wall 201 and the top inner wall 202 respectively. It can be understood that the foam outlet channel 200 is integrally arranged to extend downward in a curved shape, adopting a design with a higher outer part and a lower inner part, and the large height difference between the inside and the outside can avoid the residue of foam / liquid at the foam outlet of the product. It should be noted that since the foam will liquefy, when the height difference between the inside and the outside of the foam outlet is relatively large, even if the foam liquefies, it can only flow into the channel, and the foam remaining at the foam outlet or the liquefied foam can flow back, avoiding risks such as foam hanging, dripping of residual liquid, and residual liquid remaining on the bottle body.

[0044] In some embodiments, the foam outlet channel 200 is integrally arranged to extend downward in a curved shape, and is matched with a flared shape design with a larger outer part and a smaller inner part, so that the foam effect output by the foam outlet channel 200 is better, and the user experience can be further improved.

[0045] In some embodiments of the present application, a connection structure 230 is provided at the outer end of the foam outlet channel 200, and the connection structure 230 is used for detachably installing a shaping nozzle component 240; it can be understood that the shaping nozzle can be an external component that makes the foam form various shapes, and the foam outlet 220 of the foam outlet channel 200 can pump out various different shaping forms by adding a shaping nozzle, thereby improving the user experience.

[0046] In some embodiments, the shaping nozzle component 240 is in interference fit with the connection structure 230 through a snap line. In some other embodiments, the detachable connection manner between the connection structure 230 and the shaping nozzle component 240 can also be a common detachable connection manner such as a threaded connection. In this regard, the structure of the connection structure 230 can be adaptively adjusted to meet different connection requirements.

[0047] In some embodiments of the present application, a shaping nozzle component 240 is provided at the outer end of the foam outlet channel 200, and the shaping nozzle component 240 and the housing assembly 100 are of an integral structure. It can be understood that the shaping nozzle component 240 can also be a component designed integrally with the housing assembly 100. Adding the shaping nozzle component 240 can not only pump out personalized foam, but also further enhance the volume sense of the foam.

[0048] In some embodiments of the present application, the housing assembly 100 includes an upper cover 110 and a lower cover 120. The upper cover 110 is circumferentially and interference-sealedly disposed on the lower cover 120. The foam outlet channel 200 is formed in the upper cover 110. The lower cover 120 is formed with an input channel 121 for receiving foam, and the input channel 121 communicates with the inner end of the foam outlet channel 200. It can be understood that, in order for the foam to smoothly flow from the foaming component of the extrusion foaming container to the input channel 121 and be output through the foam outlet 220 of the foam outlet channel 200, it is necessary to seal the connection of the key components well. The upper cover 110 is liftably disposed on the lower cover 120. When the upper cover 110 is lifted, the input channel 121 communicates with the inner end of the foam outlet channel 200. When the upper cover 110 is pressed down, the upper cover 110 and the lower cover 120 are interference-sealed in the circumferential direction, thus meeting the usage requirements.

[0049] In some embodiments of the present application, a plurality of drain holes 122 are circumferentially arrayed on the inner bottom surface of the lower cover 120, and each drain hole 122 is disposed close to the side wall of the lower cover 120. It can be understood that the drain holes 122 are circumferentially provided along the inner wall of the lower cover 120. When the product is applied to a water-washing scenario, the water flowing in through the gap between the upper cover 110 and the lower cover 120 can flow out through the drain holes 122 of the lower cover 120, thereby avoiding water accumulation and dirt on the product.

[0050] In some embodiments, based on the bottom surface of the lower cover 120 and with the center position of the bottom surface of the lower cover 120 as the reference, each drain hole 122 is respectively disposed at each corner position of the inner bottom surface of the lower cover 120, so that the lower cover 120 has a good drainage effect.

[0051] In some embodiments of the present application, the upper cover 110 is movably disposed on the lower cover 120. The movement path of the upper cover 110 has a first preset position and a second preset position. When the upper cover 110 is in the first preset position, it can cut off the connection between the input channel 121 and the foam outlet channel 200. When the upper cover 110 is in the second preset position, it can make the input channel 121 communicate with the foam outlet channel 200. It can be understood that the upper cover 110 and the lower cover 120 are interference-sealed circumferentially, and the opening and closing are realized by lifting and pressing. By defining the specific positions of the first preset position and the second preset position, it is determined that when the upper cover 110 moves to the first preset position, it is in a fully open state. At this time, the user can perform the foaming operation. When the upper cover 110 moves to the second preset position, it is in a fully closed state. At this time, the foam outlet channel 200 cannot foam, and the user can perform operations such as storing the extrusion foaming container.

[0052] In some embodiments, limit members can be respectively disposed at the first preset position and the second preset position between the upper cover 110 and the lower cover 120 to limit both ends of the movement path of the upper cover 110 and serve as the first preset position and the second preset position.

[0053] In some embodiments of the present application, the upper cover 110 is axially movably disposed on the lower cover 120. A first limiting structure 310 and a second limiting structure 320 for axial positioning are provided between the upper cover 110 and the lower cover 120. The first limiting structure 310 is used to limit the upper cover 110 to a first preset position, and the second limiting structure 320 is used to limit the upper cover 110 to a second preset position. It can be understood that the first limiting structure 310 and the second limiting structure 320 are set as snap lines, and positioning and limiting are achieved through the axial snap lines.

[0054] In some embodiments of the present application, a positioning structure 400 for prompting the state is provided between the upper cover 110 and the lower cover 120. The positioning structure 400 includes a first positioning portion 410 and a second positioning portion 420 with complementary shapes. The first positioning portion 410 is adapted to be embedded in the second positioning portion 420 when the upper cover 110 is in the first preset position to achieve cooperation, and the first positioning portion 410 is adapted to completely leave the second positioning portion 420 when the upper cover 110 is in the second preset position; it can be understood that the positioning structure 400 can enhance the user's recognition of opening and closing, and avoid the occurrence of accidental opening and liquid leakage. It should be noted that corresponding concave-convex positioning structures 400 are provided between the upper cover 110 and the lower cover 120 to enhance the user's recognition of the opening and closing states of the product during use, and avoid liquid leakage problems during carrying due to forgetting or confusion. In some embodiments, some prompt characters can be added on or near the concave-convex positioning points, such as the upper and lower sides, or the current closing status can be quickly and accurately judged by changing the color feedback of different components to better prompt the state.

[0055] In some embodiments, the first positioning portion 410 is a protruding positioning point provided on the upper cover 110, and the second positioning portion 420 is a concave positioning groove provided on the lower cover 120. In other embodiments, the first positioning portion 410 is a concave positioning groove provided on the upper cover 110, and the second positioning portion 420 is a protruding positioning point provided on the lower cover 120. The protruding positioning point can be embedded in the concave positioning groove, thereby enhancing the effect of the user's recognition of opening and closing.

[0056] In some embodiments of the present application, at least one pull ring 111 is provided at the central position of the top of the upper cover 110. It can be understood that the pull ring 111 can solve the problems of difficult opening and closing, being uncomfortable to hold, and multi-scenario application. The product adopts an innovative pull ring 111 design, which is more ergonomic, and the pull ring 111 design can also have the function of hanging in many use scenarios, such as sales scenarios, bathing scenarios, etc., with multiple functions in one, bringing a better use experience to users.

[0057] In some embodiments, a through-hole pull ring 111 is provided at the center of the top of the upper cover 110, and the inner diameter is large enough for an ordinary adult index finger to pass through for lifting. The center of the circle of the pull ring 111 is located in the axial direction of the vertical center point of the upper cover 110, ensuring that the lifting force of the product is always in the vertical center direction of the upper cover 110, and the force is more uniform. The center of the circle of the pull ring 111 is close to the horizontal center point of the top surface of the upper cover 110, so as to effectively reduce the height of the product and improve the structural strength.

[0058] In some embodiments, a top cover may also be provided on the upper cover 110, and the pull ring 111 is provided on the top cover. The top cover and the upper cover 110 are assembled to form an integral component. The specific way of assembling to form the component can be ultrasonic welding, or snap-line fitting, etc.

[0059] In other embodiments, the pull ring 111 is provided on the top cover, and the top cover and the upper cover 110 may be an integrated structure, and the specific structural form can be selected according to actual needs.

[0060] Referring to Figures 1 to 4 , the extrusion foam container according to the second aspect embodiment of the present application includes the foam outlet nozzle component according to the first aspect embodiment of the present application, which can not only avoid the problems of poor foam shape and unstable abnormal accumulation ejected from the narrow channel, make the foam remaining at the foam outlet nozzle or the liquefied foam flow back, avoid the situation of foam hanging on the foam outlet nozzle and residual liquid dripping, reduce the phenomenon of residual liquid remaining on the bottle body, but also make the foam have a certain sense of release when ejected, improving the user experience.
