For the convenience of processing and use, in another embodiment, referring to Figures 1-4, the outer wall of the cylindrical structure is a smooth wall structure.

The cylindrical structure itself may have convex and concave parts, but the light wall structure of this embodiment mainly emphasizes the difference from the prior art, that is, the hairless (bristle) structure.

In another embodiment, referring to FIGS. 1-4, the brush head 130 is connected to the bottle cap 100 through a brush rod 110, and the connection method is as follows:

The brush head 130 has a cylindrical structure as a whole, and one axial end is fixedly sleeved on the brush rod 110; or

One axial end of the brush head 130 is embedded in the brush rod 110 , and the other end is exposed to the outside of the brush rod 110 . The brush head 130 adopts a cylindrical structure at least at the exposed part.

One end of the brush rod 110 is a fixed end connected to the bottle cap 100, and the other end is a connecting end 111 extending into the bottle body 200, and the brush head 130 is installed on the connecting end 111;

The fixing method of the brush rod 110 and the bottle cap 100 is an integrated structure or other fixing methods common in the prior art; the connecting end 111 only needs to ensure a stable connection with the brush head 130 .

In another embodiment, referring to FIGS. 1-4 , one axial end of the brush head 130 is fixed to the connecting end 111 through interference fit, and/or is fixed by an engaging structure.

For example, use the interference fit shown in Figure 1 and Figure 2 to fix;

For example, adopt the snap-fit structure shown in Fig. 3 and Fig. 4 to fix.

In another embodiment, referring to FIG. 1 and FIG. 2 , one axial end of the brush head 130 is fixed to the connecting end 111 , and the other axial end of the brush head 130 extends out of the connecting end 111 and is suspended.

In the embodiment of the present application, the brush head 130 is divided into two sections, namely a first section 133 suspended and a second section 134 fixed by interference fit with the connecting end 111 . The first section 133 extends continuously in the axial direction of itself, and belongs to a type of cylindrical structure.

The connection end 111 is provided with a groove 112 and the second section 134 is inserted into the groove 112 and fixed by interference fit to prevent the two components from being separated. For the convenience of processing, the second section 134 can also be wound with a metal wire to form a tight spiral structure matching the shape of the groove 112; when the first section 133 is wound with a metal wire, the second section 134 can also be the first An integral extension of section 133 .

In another embodiment, referring to FIG. 3 , FIG. 4 , and FIG. 7 , the engaging structure is a positioning portion disposed on the outer periphery of the connecting end 111 , and the hollowed out area 131 on the brush head 130 engages with the positioning portion.

The positioning portion can be, for example, a positioning rib, a protrusion, a spiral, or other engaging methods.

Taking the helical structure of the positioning part as an example, the brush head 130 is divided into two sections, namely the first section 133 (cylindrical structure of the brush head 130 ) and the second section 134 (used to fix with the positioning part of the connecting end 111 ). The second section 134 and the positioning part form an axial limiting engagement through thread fit; as shown in FIG. 7 , the second section 134 and the connecting end 111 can also form an interference fit while threading. For the convenience of processing, when the first section 133 is wound by metal wire, the second section 134 can be integrally extended from the first section 133 .

In another embodiment, referring to FIGS. 1-4 and FIG. 7 , the brush head 130 is sleeved on the outer periphery of the connecting end 111 as a whole.

When the second section 134 of the brush head 130 is sleeved on the connecting end 111 , the connecting end 111 can extend toward the bottle body 200 until reaching or exceeding the end of the brush head 130 away from the connecting end 111 . At this time, the first section 133 of the brush head 130 is also sleeved on the connecting end 111 at the same time, that is, the brush head 130 is sleeved on the outer periphery of the connecting end 111 as a whole, and at this time, the first section 133 of the brush head 130 is far away from the brush rod. The end of 110 can also be connected to the connection end 111 , that is, both ends of the brush head 130 are connected to the connection end 111 at the same time.

The connection methods between the two ends of the brush head 130 and the connection end 111 may be the same or different.

Compared with the solution in which the first section 133 is suspended, the extension of the connecting end 111 to the first section 133 can limit the radial deformation of the brush head 130 and the degree of bending of the cylindrical structure, affecting the load or the volume of cosmetics applied. It can be understood that the part where the connecting end 111 extends to the first section 133 only needs to ensure the axial connection, and the radial dimension can be changed freely, so as to further adjust the deformation amount of the first section 133 at different positions and enhance the applicability of the use scene, for example Change the angle and posture of coating according to the skin in different positions of the human body.

In another embodiment, referring to FIG. 3 , FIG. 4 , and FIG. 8 , there is a second gap A2 between the inner wall of the brush head 130 and the outer wall of the connecting end 111 .

In the embodiment of the present application, the brush head 130 is sheathed on the outer periphery of the connecting end 111 as a whole. Specifically, the size of the second gap A2 at different axial positions can be controlled by adjusting the outer diameter of the connecting end 111 at different axial positions and the inner diameter of the brush head 130 at different axial positions.

For example, a second gap A2 greater than that at both ends of the brush head 130 may be left at the axially middle portion of the brush head 130 . Compared with the single change of the radial dimension of the connecting end 111 , the adaptive change of the first section 133 makes the second gap A2 have a greater room for variation, and the applicability of the scene is enhanced.

In another embodiment, referring to Figures 1-4 and Figures 9-15, in order to adapt to the usage habits of different users or the characteristics of the coating site, the generatrix of the cylindrical structure in different embodiments is a straight line or a curve.

The generatrix of the tubular structure is a straight line or a curve, which can affect the volume of the hollow area 131 set on the side wall, thereby enhancing the applicability of the usage scenarios, such as changing the angle and posture of the coating for different positions of the skin of the human body.

When the generatrix of the cylindrical structure is a straight line, that is, the straight cylinder in Fig. 9 or Fig. 13, when the curve is the generatrix, it can be a convex arc in Fig. 10 or Fig. 14, or have a curved overall structure as shown in Fig. 11 or Fig. 15 The bottle shape, or the concave shape in the middle shown in Figure 12, in other embodiments, can also include other shapes.
