[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] refer to Figures 1 to 5 This embodiment discloses a self-wetting roller brush structure and an extrusion container.

[0037] like Figures 1 to 4 As shown, the self-wetting roller brush structure includes a connecting cover 100, a limiting seat 200, a roller brush 300, and a conveying assembly 400. The limiting seat 200 is disposed on the connecting cover 100, and the limiting seat 200 and the connecting cover 100 enclose a conveying channel 210. The roller brush 300 is rotatably disposed on the limiting seat 200 and is located at the output end of the conveying channel 210. The roller brush 300 is used to evenly apply liquid. The conveying assembly 400 is disposed on the connecting cover 100 and is configured to convey liquid to the roller brush 300 to wet the entire roller brush 300.

[0038] like Figure 1 As shown, a limiting seat 200 is movably mounted on the connecting cover 100, forming a conveying channel 210 between the two. The roller brush 300 is rotatably mounted on the limiting seat 200. The conveying assembly 400 is connected to the connecting cover 100 to convey liquid to the roller brush 300 along the conveying channel 210. Thus, the conveying assembly 400 utilizes the conveying channel 210 formed by the limiting seat 200 and the connecting cover 100 to convey a fixed amount of liquid to the surface of the roller brush 300. Simultaneously, the roller brush 300 achieves uniform liquid distribution through its rotational motion, allowing the liquid to automatically wet the entire surface of the roller brush 300. This overcomes the limitation of traditional open-type output terminals requiring manual application, achieving a stable and uniform application effect, thereby improving the user experience.

[0039] In some specific embodiments of this utility model, the roller brush 300 includes a roller 310 and two supports 320. The roller 310 has a cavity 311 that extends along the axial direction of the roller 310. Both supports 320 are rotatably connected to the limiting seat 200. Each support 320 is provided with a limiting cylinder 321 that passes through the cavity 311. The two supports 320 are configured to rotate the roller 310 on the limiting seat 200.

[0040] like Figure 1 and Figure 2 As shown, the roller 310 is a cylindrical hollow structure extending in the left and right direction. Two supports 320 are respectively set at the left and right ends of the roller 310. Specifically, each support 320 is provided with a limiting cylinder 321. The outer diameter of the limiting cylinder 321 corresponds to the inner diameter of the cavity 311. The support 320 is embedded into the two ends of the roller 310 through the corresponding limiting cylinder 321 to form a stable rotational support, so that the roller 310 can rotate freely on the limiting seat 200, ensuring that the roller brush 300 does not deviate during the rolling process. On the other hand, by adopting a split bracket 320 structure, rollers 310 of different lengths and diameters can be compatible by adjusting the outer diameter of the limiting cylinder 321 or the installation spacing of the bracket 320. Thus, by using the limiting cylinder 321 of the bracket 320 as a standardized interface, stable assembly can be achieved as long as the inner diameter of the roller 310 cavity 311 matches the outer diameter of the limiting cylinder 321. At the same time, by replacing the limiting cylinder 321 of different lengths or adjusting the spacing of the bracket 320, the same bracket 320 structure can support rollers 310 of different sizes, thereby reducing the cost of product serialization development.

[0041] Furthermore, the other end of the bracket 320 is provided with a rotating protrusion, which is arranged opposite to the limiting cylinder 321, and two limiting grooves are correspondingly provided on the limiting seat 200. The rotating protrusion is rotatably embedded in the limiting groove, so that the bracket 320 can rotate flexibly relative to the limiting seat 200, thereby achieving stable rotational support for the roller brush 300.

[0042] Furthermore, the limiting cylinder 321 has a radially extending limiting flange at one end near the rotating protrusion, which protrudes away from the rotating protrusion. When the limiting cylinder 321 is inserted into the cavity 311 of the roller 310, the limiting flange abuts against the end of the roller 310, effectively restricting the axial movement of the roller 310 along the limiting cylinder 321, ensuring that the roller brush 300 maintains stable axial positioning during rolling, and avoiding displacement or loosening.

[0043] In some specific embodiments of this utility model, the roller 310 is sleeved on one of its limiting cylinders 321, and one of its limiting cylinders 321 is sleeved on another limiting cylinder 321.

[0044] like Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 In another specific embodiment of this utility model, the axial width of the roller 310 sleeved on the bracket 320 is relatively narrow. For the roller 310 structure with limited axial space, a nested limiting sleeve 321 is used to achieve multi-layer rotational support within a limited axial dimension. Specifically, a compact layout of interlocking sleeves is adopted, so that the roller 310, the outer limiting sleeve 321, and the inner limiting sleeve 321 form a radially nested fit, providing a reliable rotational support solution for the miniaturized roller brush 300 device without increasing the axial length.

[0045] In some specific embodiments of this utility model, an opening and closing component 500 is also included. The opening and closing component 500 is connected to the limiting seat 200 and the connecting cover 100. The opening and closing component 500 achieves safety locking by controlling the opening and closing of the delivery channel 210, ensuring that the liquid is output only when needed, avoiding the risk of misoperation or leakage. It retains the convenience of operation for adults, and by adding unlocking steps for children, it fundamentally eliminates the risk of leakage or accidental ingestion of contents caused by accidental touch by children.

[0046] In some specific embodiments of this utility model, the opening and closing assembly 500 includes a liquid outlet 510, a sealing plug 520, an adjusting member 530, an opening member 540, and a closing member 550. The liquid outlet 510 is disposed on the connecting cover 100 and located within the conveying channel 210. The sealing plug 520 is disposed on the limiting seat 200 and located within the conveying channel 210, with the sealing plug 520 positioned on the side of the liquid outlet 510 closest to the roller brush 300. The connecting cover 100 and the limiting seat 200 may be equipped with either the adjusting member 530 or the opening member 540 and the closing member 550. The opening member 540 is located on the side of the closing member 550 closest to the roller brush 300. The adjusting member 530 alternately engages with the opening member 540 and the closing member 550 to separate and seal the sealing plug 520 from the liquid outlet, thereby allowing the conveying channel 210 to be in an open or closed state.

[0047] like Figure 2As shown, the limiting seat 200 is slidably mounted on the connecting cover 100, and the two together form a vertically extending conveying channel 210. The connecting cover 100 has a liquid outlet 510, while the limiting seat 200 is equipped with a sealing plug 520 located on the output side of the liquid outlet 510. In this specific embodiment, the limiting seat 200 is provided with an opening member 540 and a closing member 550 arranged vertically, and the connecting cover 100 is provided with an adjusting member 530 that cooperates with them. When the limiting seat 200 slides upward to engage the adjusting member 530 with the opening member 540, the sealing plug 520 moves upward and disengages from the liquid outlet 510, and the conveying channel 210 opens to supply liquid; when the limiting seat 200 returns downward to engage the adjusting member 530 with the closing member 550, the sealing plug 520 resets and re-closes the liquid outlet 510, and the conveying channel 210 closes to stop the liquid supply.

[0048] Thus, by sliding the limit seat 200 up and down, the sealing plug 520 is driven to control the opening and closing of the liquid outlet 510, realizing the intuitive operation of exiting the liquid from the top and closing it by pushing it down. The mechanical self-locking function also ensures complete sealing in the closed state, effectively preventing liquid leakage.

[0049] In some specific embodiments of this utility model, the adjusting member 530 is an elastic positioning protrusion, and the opening member 540 and the closing member 550 are both positioning through holes. For example... Figure 2 and Figure 4 As shown, the adjusting element 530 consists of two positioning protrusions respectively disposed at opposite ends of the side wall of the limiting seat 200. The opening element 540 and the closing element 550 consist of two sets of upper and lower positioning through holes respectively disposed on the connecting cover 100 corresponding to the positioning protrusions. When the limiting seat 200 moves upward and the elastic positioning protrusion is engaged in the upper positioning through hole, the sealing plug 520 moves upward to open the delivery channel 210 for liquid supply; when the limiting seat 200 moves downward and the elastic positioning protrusion is engaged in the lower positioning through hole, the sealing plug 520 resets and closes the delivery channel 210.

[0050] like Figure 2 and Figure 4 As shown, the limiting seat 200 has an elastic positioning protrusion on each of its two opposite side walls as an adjusting element 530. Simultaneously, upper and lower positioning through holes are respectively provided on the connecting cover 100 as an opening element 540 and a closing element 550. When the limiting seat 200 moves upward along the connecting cover 100, the two positioning protrusions simultaneously engage in the upper positioning through hole, causing the sealing plug 520 to move upward and open the delivery channel 210 to supply liquid. When the limiting seat 200 moves downward along the connecting cover 100, the positioning protrusions engage in the lower positioning through hole, causing the sealing plug 520 to reset and close the delivery channel 210. This symmetrical double-protrusion positioning structure achieves precise opening and closing control of the delivery channel 210 through up-and-down sliding, ensuring the synchronicity of the sealing action and making the liquid delivery process more precise and controllable.

[0051] In some specific embodiments of this utility model, a cover 600 is also included. The cover 600 is detachably mounted on the connecting cover 100 by a locking assembly 610. The roller brush 300 is located inside the cover 600, and the cover 600 is used to protect the roller brush 300.

[0052] In some specific embodiments of this utility model, the locking assembly 610 includes a first fastening member 611 and a second fastening member 612. The cover 600 and the connecting cover 100 are provided with the first fastening member 611 and the other is provided with the second fastening member 612. The first fastening member 611 and the second fastening member 612 cooperate to lock the cover 600 onto the connecting cover 100.

[0053] like Figures 1 to 4 As shown, the first fastening member 611 is an elastic claw, and the second fastening member 612 is a limiting protrusion. In this specific embodiment, the elastic claw is provided on the connecting cover 100, and the limiting protrusion is provided on the cover body 600. When the cover body 600 and the connecting cover 100 are aligned and installed, the elastic claw and the limiting protrusion engage with each other to produce a reliable mechanical locking effect. When disassembling, only appropriate external force needs to be applied to deform the elastic claw to easily separate it, thereby realizing convenient installation and stable locking of the cover body 600.

[0054] Furthermore, the elastic claw is equipped with a guide protrusion, which can provide tactile guidance for the user, thereby naturally guiding the user to apply the correct pressure and direction, ensuring that the force is accurately transmitted to the deformation area of ​​the elastic claw, making the unlocking process of the cover 600 more effortless and smooth.

[0055] In some specific embodiments of this utility model, the conveying assembly 400 includes a conveying pipe 410 and an anti-backflow bead 420. The upper end of the conveying pipe 410 is connected to the connecting cover 100, and the anti-backflow bead 420 is movably disposed at the lower part of the conveying pipe 410. The anti-backflow bead 420 is used to prevent liquid from flowing back into the container bottle.

[0056] In some specific embodiments of this utility model, a foaming component 700 is also included. The foaming component 700 is disposed on the connecting cover 100 and connected to the conveying component 400. The foaming component 700 is located within the conveying channel 210 and is used to convert liquid into foam. The foaming component 700 includes a foaming plug 710 and a foam refining plug 720. The foaming plug 710 is inserted into the conveying pipe 410 and is used to mix gas and liquid for foaming. The foam refining plug 720 is disposed in the conveying pipe 410 and located above the foaming plug 710. An air inlet 730 is provided on the conveying pipe 410 and is located next to the foaming plug 710. It should be noted that the foaming plug 710 and the foam refining plug 720 are conventional technical means, and their working principle and structure will not be further described here.

[0057] refer to Figure 5This embodiment discloses a self-wetting roller brush structure and a squeezing container, including a bottle body 10, a squeezing tube 20 and a self-wetting roller brush structure. A connecting cap 100 is placed on the top of the bottle body 10. One end of the squeezing tube 20 is connected to the conveying tube 410 of the conveying assembly 400, and the other end extends into the bottle body 10.

[0058] In some specific embodiments of this utility model, a pressure balancing assembly 800 is also included. The pressure balancing assembly 800 includes an upper half-groove 810, a lower half-groove 820, and a movable sealing bead 830. The upper half-groove 810 is disposed on the connecting cover 100, and the lower half-groove 820 is disposed on the conveying pipe 410. The upper half-groove 810 and the lower half-groove 820 are inserted together. A first balancing air passage 811 is formed on the upper half-groove 810. The movable sealing bead 830 is movably disposed in the first balancing air passage 811 and can block the first balancing air passage 811. A second balancing air passage 821 is provided on the lower half-groove 821, which communicates with the container bottle. A blocking slope is symmetrically provided at the lower end of the first balancing air passage 811. The blocking slope is used to prevent the movable sealing bead 830 from blocking the lower end of the first balancing air passage 811. It should be noted that the pressure balancing assembly 800 is a conventional technical means, and its working principle and structure will not be further described here. Therefore, when the container bottle is squeezed, the movable sealing bead 830 abuts against the upper end of the first balance air passage 811, and the pressure inside 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 830 falls back, the first balance air passage 811 opens, and external air enters the container bottle through the second balance air passage 821.

[0059] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments.
