Description

Technical Field

[0001] This invention relates to the field of eyelash brush technology, and in particular to a rotatable eyelash brush. Background Technology

[0002] Mascara brushes are familiar to beauty-conscious women. They mainly consist of a handle, a shaft, and bristles. When using one, hold the handle, dip the bristles in mascara, and then brush your lashes using a crisscross or upward motion to make them more curled and shapely, thus making your eyes more vibrant.

[0003] Traditional mascara brushes have a fixed brush head, and the brush head is controlled by wrist movement to apply mascara to the eyelashes. However, relying on wrist movement to control the brush head results in poor stability.

[0004] Among existing patents, Chinese patent application number 202022394412.1 discloses an electrostatic adsorption rotatable mascara brush, including a brush head, a shaft, and a base. The shaft is located in the middle of the base, and the brush head is located at the end of the shaft furthest from the base. A power source is located at the bottom of the base, and a rotary motor is located in the middle. The working end of the rotary motor is fixedly connected to the shaft, which is rotatably connected to the base. An electrostatic device is located inside the brush head, connected to the power source via a wire. A control switch for controlling the rotary motor is located around the base. This patent uses a rotary motor to drive the brush head to rotate, and the brush head and electrostatic device work together to attract eyelashes. While it can automatically attract and rotate eyelashes, reducing manual operation and minimizing eyelid injury caused by accidental touches, and preventing makeup smudging, the structure is complex, with many electrical components, requiring a power supply, resulting in high manufacturing and usage costs.

[0005] Therefore, the defects are very obvious, and a solution is urgently needed. Summary of the Invention

[0006] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a rotatable eyelash brush.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rotatable eyelash brush includes a pickup, a rotating cap, a damping element, a brush handle, and a brush head. The damping element is fitted onto the bottom of the pickup, and the top of the rotating cap is fitted over the damping element and the bottom of the pickup. The rotating cap is rotatably connected to the pickup via the damping element. The top of the brush handle is mounted on the bottom of the rotating cap, and the brush head is mounted on the bottom of the brush handle. The damping element provides damping force to the rotating cap so that the rotating cap can stop at any angle. The central axis of the pickup is set at an angle to the central axis of the rotating cap.

[0009] Furthermore, the bottom of the pickup component is provided with a limiting plate and a hook component provided on the bottom surface of the limiting plate. The central axis of the hook component is parallel to the central axis of the rotating cover. An installation space is formed between the limiting plate and the hook part of the hook component, and the damping component is fitted into the installation space.

[0010] Furthermore, the damping component has a central shaft with an insertion hole, and a groove is recessed at the bottom edge of the insertion hole. The main body of the hook component is inserted into the insertion hole, and the hook part of the hook component can be locked in the groove.

[0011] Furthermore, the inner wall of the socket is provided with an inner anti-rotation cutting surface, and the main body side wall of the hook is provided with an outer anti-rotation cutting surface, with the inner anti-rotation cutting surface abutting against the outer anti-rotation cutting surface.

[0012] Furthermore, the damping component includes a mounting ring fitted around the hook and located in the mounting space, and a damping ring embedded in the peripheral sidewall of the mounting ring, the damping ring being in close contact with the inner wall of the rotating cover.

[0013] Furthermore, a limiting ring is protruding from the top inner wall of the rotating cover. The limiting ring is sandwiched between the top surface of the limiting plate and the mounting ring, and the mounting ring is sandwiched between the limiting ring and the hook.

[0014] Furthermore, a receiving cavity is formed between the inner wall of the rotating cover and the top surface of the limiting ring, and the limiting plate is received in the receiving cavity.

[0015] Furthermore, the snap hook includes at least two snap hooks, or the snap hook is a snap hook ring.

[0016] Furthermore, the top of the brush rod is provided with an insertion head, and the bottom surface of the insertion head is provided with an internal threaded sleeve around the brush rod, forming a screwing space between the internal thread of the internal threaded sleeve and the outer wall of the brush rod.

[0017] Furthermore, the rotatable mascara brush also includes a bottle body and a sealing scraper embedded in the bottle opening. The rotating cap is detachably placed over the bottle opening, and the brush handle and brush head can extend into the bottle body after passing through the central hole of the sealing scraper.

[0018] The beneficial effects of this invention are as follows: In practical applications, the angle formed by the pickup and the rotating cover is outward, and the pickup is held between the index and middle fingers. At this time, the index finger and thumb can be placed outside the rotating cover to achieve a handheld rotating mascara brush. When it is necessary to rotate the brush handle and brush head, the index finger and thumb work together to twist the rotating cover, so that the rotating cover can drive the brush handle and brush head to rotate relative to the rotating cover, thereby increasing the rotation angle variation of the brush head during use, which is beneficial for users to better complete eyelash makeup and reduce the burden on the wrist during eyelash makeup; the rotating cover can rotate 360° relative to the pickup; when the index finger and thumb release the twisting force on the rotating cover, the damping component applies a damping force to the rotating cover. Under the action of this damping force, the rotating cover can stay in the current position, so that the rotating cover will not rotate arbitrarily relative to the pickup, thereby ensuring the stability of the brush head during use. Of course, when users want to use the same eyelash makeup technique as traditional mascara brushes, i.e., without rotating the brush head, they can directly hold the pick-up piece or rotate the cap to complete the eyelash makeup. In this case, the usage is the same as with traditional mascara brushes, where the brush head is controlled by wrist movement to complete the eyelash makeup. The present invention has a simple and ingenious structure, low cost, and allows the brush head to be rotated during eyelash makeup application, making it easy to change the angle of the brush head and effectively reducing the burden on the wrist during eyelash makeup application.

[0025] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0026] like Figures 1 to 4 As shown, the present invention provides a rotatable eyelash brush, which includes a pickup 1, a rotating cover 2, a damping element 3, a brush handle 4, and a brush head 5. The damping element 3 is sleeved on the bottom of the pickup 1, and the top of the rotating cover 2 is sleeved on the outside of the damping element 3 and the bottom of the pickup 1. The rotating cover 2 is rotatably connected to the pickup 1 via the damping element 3. The top of the brush handle 4 is mounted on the bottom of the rotating cover 2, and the brush head 5 is mounted on the bottom of the brush handle 4. The damping element 3 provides damping force to the rotating cover 2 so that the rotating cover 2 can stay at any angle. The central axis of the pickup 1 is set at an angle to the central axis of the rotating cover 2.

[0027] In practical applications, the angle formed by the pickup 1 and the rotating cover 2 is oriented outwards, and the pickup 1 is held between the index finger 28 and the middle finger. At this time, the index finger 28 and the thumb 29 can be placed outside the rotating cover 2 to achieve handheld rotation of the mascara brush. When it is necessary to rotate the brush handle 4 and the brush head 5, the index finger 28 and the thumb 29 work together to twist the rotating cover 2, so that the rotating cover 2 can drive the brush handle 4 and the brush head 5 to rotate relative to the rotating cover 2, thereby increasing the rotation angle variation of the brush head 5 during use, which is beneficial for users to better complete eyelash makeup and reduce the burden on the wrist during eyelash makeup. The rotating cover 2 can rotate 360° relative to the pickup 1. When the index finger 28 and the thumb 29 release the twisting force on the rotating cover 2, the damping component 3 applies a damping force to the rotating cover 2. Under the action of this damping force, the rotating cover 2 can stay in the current position, so that the rotating cover 2 will not rotate arbitrarily relative to the pickup 1, thereby ensuring the stability of the brush head 5 during use. Of course, if the user wants to use the same eyelash makeup technique as a traditional mascara brush, that is, without needing to rotate the angle of the brush head 5, they can directly hold the pick-up piece 1 or rotate the cover 2 to complete the eyelash makeup. In this case, it is the same as the use of a traditional mascara brush, where the brush head 5 is controlled by wrist movement to complete the eyelash makeup. The present invention has a simple and ingenious structure, low cost, and allows the brush head 5 to be rotated during the eyelash makeup process, making it easy to change the angle of the brush head 5, effectively reducing the burden on the wrist when applying eyelash makeup.

[0028] Specifically, the angle between the central axis of the pickup 1 and the central axis of the rotating cover 2 is 35° to 65°; preferably, the angle between the central axis of the pickup 1 and the central axis of the rotating cover 2 is 45°. This structural design makes it easy for the user to hold the pickup 1 and also facilitates the user to easily twist the rotating cover 2.

[0029] Specifically, the pickup component 1 has a recessed clamping groove 25 in the middle, and the pickup component 1 is gourd-shaped. When the pickup component 1 is held by the index finger 28 and the middle finger, the index finger 28 and the middle finger are respectively accommodated on both sides of the clamping groove 25, the outer end of the pickup component 1 is located outside the back of the hand, and the inner end of the pickup component 1 is located inside the palm. This structural design makes it more comfortable for the user to hold the pickup component 1.

[0030] In this embodiment, the bottom of the pickup 1 is provided with a limiting plate 6 and a hook 7 disposed on the bottom surface of the limiting plate 6. The central axis of the hook 7 is parallel to the central axis of the rotating cover 2. An installation space 8 is formed between the limiting plate 6 and the hook portion 11 of the hook 7, and the damping member 3 is fitted into the installation space 8. This structural design allows the damping member 3 to be stably installed at the bottom of the pickup 1.

[0031] In this embodiment, the damping member 3 has a central shaft with an insertion hole 9, and a groove 10 is recessed at the bottom edge of the insertion hole 9. The main body of the hook member 7 is inserted into the insertion hole 9, and the hook part 11 of the hook member 7 can be locked into the groove 10. This structural design facilitates the assembly of the damping member 3 and the hook member 7, and the damping member 3 is not easily detached from the hook member 7.

[0032] In this embodiment, the inner wall of the insertion hole 9 is provided with an inner anti-rotation tangential surface, and the main body side wall of the hook member 7 is provided with an outer anti-rotation tangential surface. The inner anti-rotation tangential surface abuts against the outer anti-rotation tangential surface. After the hook member 7 and the damping member 3 are assembled, the outer anti-rotation tangential surface and the inner anti-rotation tangential surface fit tightly together to limit each other, thereby preventing relative rotation between the damping member 3 and the hook member 7. This prevents the damping member 3 from rotating relative to the pickup member 1, so that the damping member 3 will not rotate with the rotating cover 2. This allows the damping member 3 to stably apply damping force to the rotating cover 2, which is beneficial to improving the stability of the invention.

[0033] In this embodiment, the damping component 3 includes a mounting ring 14 fitted around the hook component 7 and located in the mounting space 8, and a damping ring 15 embedded in the peripheral sidewall of the mounting ring 14. The damping ring 15 is in close contact with the inner wall of the rotating cover 2. Specifically, the damping ring 15 can be an O-ring or a soft plastic ring, such as a rubber ring. By applying damping force to the rotating cover 2 through the damping ring 15, the rotating cover 2 will not wobble or produce abnormal noise when rotated, and the damping feel / damping force during rotation can be increased.

[0034] In this embodiment, a limiting ring 16 protrudes from the top inner wall of the rotating cover 2. The limiting ring 16 is sandwiched between the limiting plate 6 and the top surface of the mounting ring 14, and the mounting ring 14 is sandwiched between the limiting ring 16 and the hook portion 11. This structural design ensures that the rotating cover 2, the damping component 3, and the pickup component 1 are assembled securely and will not loosen, and also prevents the pickup component 1 from being over-assembled inside the rotating cover 2.

[0035] In this embodiment, a receiving cavity 17 is formed between the inner wall of the rotating cover 2 and the top surface of the limiting ring 16, and the limiting plate 6 is housed in the receiving cavity 17; this structural design makes the rotating cover 2 and the picking member 1 compact.

[0036] Specifically, the depth of the accommodating cavity 17 is equal to the thickness of the limiting plate 6, so that the top surface of the limiting plate 6 is flush with the top surface of the rotating cover 2, resulting in an aesthetically pleasing appearance.

[0037] In this embodiment, the latching component 7 includes at least two latching hooks. Specifically, there are two latching hooks, which are arranged symmetrically.

[0038] In another embodiment, the hook 7 is a hook ring.

[0039] Specifically, the top edge of the socket 9 is provided with a guide surface 23, and the bottom side of the hook portion 11 of the hook member 7 is provided with a guide slope 24, which is used to abut against the guide surface 23. During the process of inserting the hook member 7 into the socket 9, the guide slope 24 abuts against the guide surface 23, which facilitates the easy insertion of the hook member 7 into the socket 9; in addition, when the hook member 7 includes at least two snap hooks, the socket 9 is a square hole. During the process of inserting the hook member 7 into the socket 9, the guide surface 23 presses against the guide slope 24, so that the snap hook can undergo a recoverable elastic deformation, which facilitates the quick insertion of the hook member 7 into the socket 9, and the hook portion 11 of the snap hook engages with the slot 10.

[0040] In this embodiment, the top of the brush rod 4 is provided with an insertion head 18, and the bottom surface of the insertion head 18 is provided with an internal threaded sleeve 19 around the brush rod 4. The internal thread of the internal threaded sleeve 19 and the outer side wall of the brush rod 4 form a screwing space 20. In practical applications, the bottle mouth of the bottle body 21 is aligned with the screwing space 20, and the bottle body 21 or the rotating cap 2 is screwed on, so that the external thread of the bottle mouth of the bottle body 21 is threadedly connected with the internal threaded sleeve 19, thereby causing the bottle mouth of the bottle body 21 to be gradually screwed into the screwing space 20 until the rotating cap 2 closes the bottle mouth of the bottle body 21.

[0041] Specifically, a ring 27 extends outward from the top surface of the insertion head 18, and a counterweight 26 is embedded in the ring 27. The counterweight 26 serves to balance the weight, improving the feel of the user holding the pickup 1 and the rotating cover 2. During manufacturing or use, the counterweight 26 of different weights can be disassembled or replaced to change the weighting effect, which can meet the needs of different users to a certain extent.

[0042] Specifically, the bottom end face of the brush rod 4 is recessed with an insertion hole, and the brush head 5 is provided with an insertion rod, which is inserted into the insertion hole. This structural design facilitates the assembly and disassembly of the brush rod 4 and the brush head 5, and also facilitates the replacement of the same or different brush heads 5.

[0043] Specifically, the outer wall of the insertion head 18 is glued to the inner wall of the rotating cover 2, so that the insertion head 18 can be firmly installed inside the rotating cover 2.

[0044] In this embodiment, the rotatable mascara brush also includes a bottle body 21 and a sealing scraper 22 embedded in the bottle opening of the bottle body 21. The rotating cap 2 is detachably placed over the bottle opening of the bottle body 21. The brush handle 4 and brush head 5 can pass through the central hole of the sealing scraper 22 and extend into the bottle body 21. The bottle body 21 is used to store mascara. When the rotating cap 2 is closed on the bottle body 21, the brush handle 4 passes through the central hole of the sealing scraper 22, and the sealing scraper 22 is in close contact with the outer wall of the brush handle 4 to seal the mascara in the bottle body 21. When the brush handle 4 and brush head 5 are pulled out of the bottle body 21, the sealing scraper 22 can scrape away excess mascara on the brush handle 4 and brush head 5, which will not easily cause waste of mascara and will not affect the mascara makeup effect due to excessive mascara on the brush head 5.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
