Description

Technical Field

[0001] This utility model relates to the field of beauty tools, and in particular to an eyebrow trimmer with a retractable blade. Background Technology

[0002] An eyebrow trimmer is a beauty tool that helps remove unwanted eyebrow hairs. Eyebrow trimmers are generally divided into two types: manual and electric. Manual eyebrow trimmers are favored by people who need precise eyebrow trimming because they are more flexible to use and allow for better control of the trimming angle and pressure.

[0003] Manual eyebrow trimmers typically feature a long, narrow blade design or a crank-type blade design. The long, narrow blade design places higher demands on the user's angle and direction of force during eyebrow trimming. However, existing crank-type blades lack a telescopic function, requiring the use of a protective sleeve to protect the blade from external damage and prevent accidental contact with the blade's edge, ensuring safe use. However, the protective sleeve is small, easily lost, or difficult to find in a makeup case. Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide an eyebrow trimmer with a retractable blade, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A retractable eyebrow trimmer includes a handle, a blade, and a drive structure. The handle includes a straight handle portion and a crank portion, the straight handle portion being connected to the crank portion. An opening is provided on one side of the straight handle portion, and the blade is telescopically disposed in the opening. The drive structure is disposed within the straight handle portion and the crank portion, and the drive structure drives the blade to extend or retract within the opening.

[0006] Preferably, the opening is provided with an adhesive strip along its length.

[0007] Preferably, the straight shank portion includes an integral straight shank shell and a separate straight shank shell, the crank portion includes an integral crank shell and a separate crank shell, the integral straight shank shell and the integral crank shell are integrally formed, the separate straight shank shell is connected to the integral straight shank shell, and the separate crank shell is connected to the integral crank shell.

[0010] Preferably, the blade is detachably mounted on the handle.

[0011] Preferably, the driving structure includes at least a guide block and a push rod. The blade is provided with at least two sets of guide posts. The guide block is provided with a slanted groove corresponding to the guide post, and the straight shank is provided with a straight groove corresponding to the guide post. The guide post slides in cooperation with the slanted groove and the straight groove so that the blade is driven to move up and down reciprocally when the guide block moves left and right. The rear end of the guide block is provided with a guide block, and the front end of the push rod is provided with a guide groove. The guide block is slidably disposed in the guide groove. The front and rear sides of the guide block are provided with a first guide slope, and the front and rear walls of the guide groove are provided with a second guide slope. The first guide slope and the second guide slope are adapted to each other so that the guide block is driven to move left and right reciprocally when the push rod moves linearly.

[0012] Preferably, a number of reinforcing ribs are distributed along the length direction inside the straight handle, and each reinforcing rib is provided with a protrusion. The back of the guide slider is provided with a groove that matches the protrusion, so that the guide slider is disposed in the straight handle in a left-right reciprocating motion.

Detailed Implementation

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] refer to Figures 1 to 6A retractable eyebrow trimmer includes a handle 10, a blade 20, and a guide slider 30 and a push rod 40 as driving structures. The handle 10 includes a straight handle portion 11 and a crank portion 12, with the straight handle portion 11 connected to the crank portion 12. An opening 13 is provided on one side of the straight handle portion 11. The blade 20 is retractably disposed within the opening 13, meaning the blade 20 can reciprocate vertically within the straight handle portion 11. Cutting teeth 21 are provided on the side of the blade 20 near the opening 13. The guide slider 30 is reciprocating horizontally within the straight handle portion 11. When the push rod reciprocates left and right, it drives the blade 20 to reciprocate up and down. The push rod 40 is set in the crank part 12 and reciprocates in a straight line. When the push rod 40 reciprocates in a straight line, it drives the guide slider 30 to reciprocate left and right. It should be understood that when in use, the push rod 40 pushes the guide slider 30 to move, and the guide slider 30 simultaneously drives the blade 20 to extend out of the opening 13. After use, the push rod 40 pulls the guide slider 30 to move, and the guide slider 30 simultaneously drives the blade 20 to retract from the opening 13, so as to realize the function of blade 20 corner retraction between the straight shank part 11 and the crank part 12.

[0026] In addition, the opening 13 is provided with a rubber strip along its length. The rubber strip is used to remove hair from the blade 20. When the blade 20 retracts back to the straight shank 11, the blade 20 rubs against the rubber strip, causing the hair to stick to the rubber strip, making it easy for the user to clean.

[0027] Specifically, the straight shank portion 11 includes a straight shank integral shell 111 and a straight shank split shell 112, and the crank portion 12 includes a crank integral shell 121 and a crank split shell 122. The straight shank integral shell 111 and the crank integral shell 121 are integral structures, the straight shank split shell 112 is connected to the straight shank integral shell 111, and the crank split shell 122 is connected to the crank integral shell 121. The blade 20 is detachably mounted on the shank body 10. This structure uses a combination of three shells. When the blade 20 is damaged and needs to be replaced, only the straight shank split shell 112 needs to be removed to separate the straight shank split shell 112 from the crank portion 12, and then the blade 20 can be replaced. The blade 20 needs to be installed on the side of the guide slider 30 away from the crank integral shell 121, otherwise it will be blocked by the guide slider 30. Based on this, both the integrated crankshaft housing 111 and the separate crankshaft housing 112 are made of plastic, preferably ABS; both the integrated crankshaft housing 121 and the separate crankshaft housing 122 are made of zinc alloy and / or plastic, with zinc alloy having better strength, and if plastic is used, ABS is preferred.

[0028] Specifically, the blade 20 is provided with at least two sets of guide posts 22, and the guide slider 30 is provided with inclined grooves 31 corresponding to the guide posts 22. The straight shank split shell 112 of the straight shank part 11 is provided with straight grooves corresponding to the guide posts 22. The guide posts 22 are slidably engaged with the inclined grooves 31 and the straight grooves. It should be understood that each set of guide posts 22 extends outward on both sides of the blade 20. One side of the guide post 22 is slidably engaged with the inclined grooves 31, and the other side of the guide post 22 is slidably engaged with the straight grooves. This structure allows the blade 20 to only move up and down within the straight shank part 11. By utilizing the sliding plate engagement between the guide posts 22 and the inclined grooves 31, the guide slider 30 moves left and right, and its pushing force forces the blade 20 to move up and down, causing the blade 20 to extend out of the opening 13 or retract into the opening 13.

[0029] Specifically, a number of reinforcing ribs 113 are distributed along the length direction inside the straight handle 11, and each reinforcing rib 113 is provided with a protrusion 114. The back of the guide slider 30 is provided with a groove 32 that matches the protrusion 114. This structure restricts the guide slider 30 from reciprocating left and right in the straight handle 11, ensuring the stability of the guide slider 30's movement.

[0030] Specifically, the rear end of the guide block 30 is provided with a guide block 33, and the front end of the push rod 40 is provided with a guide groove 41. The guide block 33 is slidably disposed in the guide groove 41. In the corner retraction structure, especially the first guide slope provided on the front and rear sides of the guide block 33 and the second guide slope provided on the front and rear walls of the guide groove 41, the first guide slope and the second guide slope in this structure are adapted to each other, so that the push rod 40 can drive the guide block 30 to reciprocate left and right in the straight handle 11 whether it moves forward or backward in a straight line.

[0031] Specifically, a through groove 123 is provided on the side of the crank part 12, and a paddle part 42 is provided on the push rod 40 that slides in cooperation with the through groove 123. The paddle part 42 extends to the outside of the through groove 123. In actual use, the crank part 12 is generally held by hand, and the paddle part 42 driven by the hand is provided on the crank part 12, which is more convenient and comfortable to use.

[0032] Specifically, the push rod 40 is provided with an elastic plate 43, which has a first arc groove 431 and a second arc groove 432. The inner wall of the crank part 12 is provided with a limiting block 124. When the push rod 40 is driven by hand to move forward or backward in a straight line, the first arc groove 431 and the second arc groove 432 on the elastic plate 43 abut against the limiting block 124 respectively. The elastic preload between the elastic plate 43 and the limiting block 124 provides a positioning function for the push rod 40, so that the person can adjust the eyebrow trimmer to the open or closed state at the first time. In the eyebrow trimmer extended and retracted open state, the first arc groove 431 abuts against the limiting block 124, and in the eyebrow trimmer extended and retracted closed state, the second arc groove 432 abuts against the limiting block 124, thereby realizing the positioning of the push rod 40 and preventing the blade 20 from sliding naturally.
