Description

Technical Field

[0001] This utility model relates to the field of eyelash brush technology, specifically an electric rotating eyelash brush. Background Technology

[0002] A mascara brush is an eye makeup tool used to groom and separate lashes before and after applying mascara, or in conjunction with mascara. Mascara brushes come in various shapes and sizes to suit different makeup needs and lash types. Common types of mascara brushes include curved brush heads, tapered brush heads, spiral brush heads, mini brush heads, and urchin-shaped brush heads. In addition, there are double-ended mascara brushes (one end for volumizing and the other for lengthening) and extra-large brush heads (for creating a false lash effect).

[0003] For example, patent publication number CN213604955U provides an electrostatic adsorption rotatable mascara brush, including a mascara brush head, a mascara shaft, and a mascara base. The mascara shaft is located in the middle of the mascara base, and the mascara brush head is located at the end of the mascara shaft away from the mascara base. A power source is located at the bottom of the mascara base, and a rotary motor is located in the middle of the mascara base. The working end of the rotary motor is fixedly connected to the mascara shaft, and the mascara shaft is rotatably connected to the base. An electrostatic device is located inside the mascara brush head, and the electrostatic device is connected to the power source via a wire. A control switch for controlling the rotary motor is located around the mascara base. This invention allows the mascara shaft and the mascara base to rotate in coordination, driving the mascara brush head to rotate. The mascara brush head and the electrostatic device work together to attract mascara. This invention automatically attracts and rotates mascara, reducing manual operation and minimizing eyelid injury caused by accidental handling, and does not smudge eye makeup.

[0004] In the above solution, the eyelashes are bent and shaped by rotating the eyelash brush head. However, during the process of shaping the eyelashes by rotating the eyelash brush head, the user needs to control the entire eyelash brush to move up or down along the bending direction of the eyelashes to cooperate with the device to control the bending of the eyelashes. This process of moving the entire eyelash brush up and down is not easy to control and is prone to tilting or moving up or down, which may have an adverse effect on the eye makeup effect.

[0005] Therefore, an electric rotating eyelash brush is proposed to address the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figure 1 - Figure 5This utility model provides an electric rotating mascara brush, including a mascara brush body 1, a rotating brush head 11 installed at one end of the mascara brush body 1, a cover 2 provided on the outside of the mascara brush body 1, a locking groove 21 opened on one side of the cover 2, a displacement slider 3 slidably installed between the inner walls of the locking groove 21, an elastic retraction rod 31 fixedly connected to the end face of the displacement slider 3, an annular retaining sleeve 32 fixedly connected to the output end face of the elastic retraction rod 31, an installation ring 4 fixedly fitted on the outer wall of the mascara brush body 1, a circular retaining plate 41 fixedly connected in the groove of the outer wall of the installation ring 4, the circular retaining plate 41 and the circular retaining sleeve engaging with each other, the mascara brush body 1 rotates and contacts the eyelashes through the rotating brush head 11, and the installation ring 4 is fixedly fitted on the outer wall of the mascara brush body 1 and slides in the groove. The displacement slider 3 inside the mounting groove 21 achieves linkage between the cover 2 and the displacement slider 3 through the interlocking of the annular sleeve 32 at one end of the elastic retraction rod 31 and the circular plate 41. Before applying eyelash makeup, the entire body of the mascara brush 1 is pulled outward to overcome the elastic retraction force of the elastic retraction rod 31 until the mascara brush body 1 is completely separated from the mounting groove 21. Then, the mascara brush body 1 is rotated to a state perpendicular to the cover 2. At this time, the entire cover 2 can move up and down with the displacement slider 3 under the restriction of the mounting groove 21, replacing the process of the user moving the mascara brush body 1 up and down. As long as the state of the cover 2 is held, the up and down movement of the mascara brush body 1 will not be skewed, ensuring the makeup effect of the rotating brush head 11 on the eyelashes.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, semi-circular locking blocks 42 are fixed to both ends of the mounting ring 4 near the side wall of the housing 2. The end face of the semi-circular locking block 42 is parallel to the side profile of the mascara brush body 1. The side wall of the housing 2 is provided with a side wall slide rail 22, which is symmetrically opened outside the mounting groove 21. The semi-circular locking block 42 and the side wall slide rail 22 are the structures of the mounting ring 4 and the mascara brush body 1, respectively, which cooperate with the displacement component 5 to rotate and limit the entire mascara brush body 1.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, displacement components 5 are provided on both outer walls of the housing 2. The displacement components 5 include a semi-circular plate 51. A lifting frame 52 is symmetrically fixed to the outer wall of the semi-circular plate 51. The lifting frame 52 is slidably installed in the side wall slide rail 22. The semi-circular plate 51 is installed by the mutual engagement between the lifting frame 52 and the side wall slide rail 22, so as to realize the linkage between the mascara brush body 1 and the displacement components 5.

[0030] like Figure 1 , Figure 2 and Figure 5As shown, the semicircular plate 51 has a semicircular slot 53 in its semicircular cross section. The semicircular slot 53 can engage with the semicircular block 42. Electric telescopic rods 54 are fixed to both sides of the semicircular plate 51. One end of each electric telescopic rod 54 is fixed to the side wall of the cover 2 through a bracket. When the mascara brush body 1 and the displacement slider 3 are rotated outward, the semicircular block 42 engages with the semicircular slot 53. At this time, the relative angle between the cover 2 and the displacement slider 3 is limited. The mascara brush body 1 can reciprocate within the track range of the mounting groove 21 following the displacement slider 3. The electric telescopic rod 54 provides output force for this reciprocating movement. The electric telescopic rods 54 on both sides of the semicircular block 42 will perform synchronous reverse contraction or expansion movements to control the up and down movement of the mascara brush body 1 as a whole.

[0031] like Figure 2 As shown, a brush head cover plate 6 is hinged to the end of the cover 2 near the rotating brush head 11 via a bracket. The brush head cover plate 6 has an adaptation groove 61 on the side wall near the cover 2. The adaptation groove 61 can cooperate with one end of the mounting groove 21. A semi-circular rubber pad 62 is fixed to the inner wall of the opening of the adaptation groove 61. The semi-circular rubber pad 62 can fit against the outer wall of one end of the rotating brush head 11.

[0032] During operation, the brush head cover 6, hinged to one end of the housing 2, can cover the rotating brush head 11 when the mascara brush body 1 is not in operation by the mutual cooperation between the adaptation groove 61 on its side wall and the snap-fit ​​groove 21, preventing the rotating brush head 11 from being contaminated by external impurities when not in use. The semi-circular rubber pad 62 can fill the gap between the brush head cover 6 and the outer wall of the rotating brush head 11, ensuring the airtightness of the fit between the brush head cover 6 and the housing 2.

[0033] Working principle: The mascara brush body 1 rotates and contacts the eyelashes through the rotating brush head 11. The mounting ring 4 is fixedly fitted on the outer wall of the mascara brush body 1. The displacement slider 3, which slides in the mounting groove 21, achieves linkage between the cover 2 and the displacement slider 3 through the interlocking of the annular sleeve 32 at one end of the elastic contraction rod 31 and the circular plate 41. Before applying mascara, the mascara brush body 1 is pulled outward to overcome the elastic contraction force of the elastic contraction rod 31 until the mascara brush body 1 is completely separated from the mounting groove 21. Then, the mascara brush body 1 is rotated to a state perpendicular to the cover 2. At this time, the cover 2 can move up and down with the displacement slider 3 under the restriction of the mounting groove 21, replacing the process of the user moving the mascara brush body 1 up and down. As long as the state of the cover 2 is held, the up and down movement of the mascara brush body 1 will not be skewed, ensuring the makeup effect of the rotating brush head 11 on the eyelashes. The semi-circular plate 51 is connected to the side wall slide rail 22 through the hanging bracket 52. The interlocking mechanism between the two components is installed to achieve linkage between the mascara brush body 1 and the displacement component 5. When the mascara brush body 1 and the displacement slider 3 are rotated outward, the semi-circular locking block 42 and the semi-circular locking groove 53 are interlocked. At this time, the relative angle between the cover 2 and the displacement slider 3 is limited. The mascara brush body 1 can reciprocate within the track range of the locking groove 21 following the displacement slider 3. The electric telescopic rod 54 provides output force for this reciprocating movement. The electric telescopic rods 54 located on both sides of the semi-circular locking block 42 will perform synchronous reverse contraction or expansion movements to control the up and down movement of the mascara brush body 1 as a whole. The brush head cover 6 hinged to one end of the cover 2 can cover the rotating brush head 11 when the mascara brush body 1 is not in use by the mutual cooperation between its side wall adaptation groove 61 and the locking groove 21, preventing the rotating brush head 11 from being contaminated by external impurities when not in use. The semi-circular rubber pad 62 can fill the gap between the brush head cover 6 and the outer wall of the rotating brush head 11.
