Description

Technical Field

[0001] This utility model relates to the field of hair styling tools, and in particular to an electric hair clipper. Background Technology

[0002] Electric hair clippers are a common hair-cutting tool, often used to trim human hair or animal fur. Electric hair clippers generally consist of a housing, a blade assembly mounted at the front of the housing, and a drive motor, power supply, and control circuit board housed within the housing. The drive motor, through a transmission mechanism, drives the moving blades of the blade assembly to reciprocate laterally, working in conjunction with the stationary blades of the blade assembly to trim the hair.

[0003] Traditional electric clippers typically use an internal rotor motor as the drive motor. However, with the continuous development and progress of the hair styling tool industry, electric clippers driven by external rotor motors have also emerged in existing technologies.

[0004] Currently available electric hair clippers based on external rotor motors typically have a viewing window on the casing, allowing users to observe the external rotor motor and enhance the user experience. However, because the external rotor rotates at high speed during operation, it is often difficult for users to clearly observe the surface of the external rotor through the viewing window, thus failing to meet actual user needs.

[0005] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0006] The purpose of this utility model is to provide an electric clipper to address the defects and shortcomings of the existing technology.

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

[0008] An electric hair clipper includes a housing, a blade assembly, an outer rotor motor, and a circuit board. The blade assembly is disposed at the front end of the housing, and the outer rotor motor and the circuit board are both disposed inside the housing. The outer rotor of the outer rotor motor is drivenly connected to the blade assembly. The housing is provided with a viewing window that allows observation of the outer peripheral wall of the outer rotor. The clipper is characterized in that: a strobe light corresponding to the viewing window is also disposed inside the housing. The strobe light and the outer rotor motor are both electrically connected to the circuit board, and the light generated by the strobe light can illuminate the outer peripheral wall of the outer rotor.

[0009] Furthermore, the housing is provided with a strobe control switch corresponding to the strobe light, and the strobe control switch is electrically connected to the circuit board.

[0010] Furthermore, the strobe light is located at the rear end of the outer rotor motor, and the light generated by the strobe light is directed toward the outer peripheral wall of the outer rotor.

[0011] Furthermore, the outer casing is provided with an inner shell and a mounting bracket. The mounting bracket is located at the front of the inner shell, and a receiving cavity is formed between the mounting bracket and the inner shell. The outer rotor motor is located in the receiving cavity, and the mounting bracket has a hollow area corresponding to the outer rotor.

[0012] Furthermore, the mounting bracket is provided with a slot, and the strobe light is inserted into the slot;

[0013] And / or, the mounting bracket is provided with a fixing buckle, and the strobe light is provided with a snap-fit ​​that engages with the fixing buckle.

[0014] Furthermore, a lighting lamp is provided inside the housing, the lighting lamp is electrically connected to the circuit board, the light generated by the lighting lamp is directed towards the front end of the housing, and the front end of the housing is provided with a light-transmitting area corresponding to the lighting lamp.

[0015] Furthermore, the housing is provided with a lighting control switch corresponding to the lighting lamp, and the lighting control switch is electrically connected to the circuit board.

[0016] Furthermore, the outer peripheral wall of the outer rotor is provided with a pattern. When the outer rotor rotates, the pattern can be observed to rotate synchronously with the outer rotor through the viewing window, and the light generated by the strobe lamp can illuminate the pattern.

[0017] Furthermore, the outer shell includes a bottom shell and a front shell that are adapted to each other, and the viewing window is disposed on the front shell.

[0018] Furthermore, the faceplate is provided with a decorative cover covering the outside of the viewing window, and the decorative cover is detachably fixed to the faceplate by a magnetic attachment.

[0019] The beneficial effects of this utility model are as follows: The electric clipper provided by this utility model has a strobe light installed inside the housing. The light generated by the strobe light can illuminate the outer peripheral wall of the outer rotor. As long as the flashing frequency of the strobe light is set to be close to or synchronized with the rotation speed of the outer rotor, when the outer rotor motor is working, under the action of the strobe light, when the user observes the outer rotor through the viewing window, the high-speed rotating outer rotor can visually appear to rotate slowly or even stand still. This allows the user to clearly observe the surface condition of the outer rotor, which is beneficial to meeting the user's actual usage needs. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] See Figures 1 to 7 An electric hair clipper includes a housing 1, a blade assembly 2, an external rotor motor 3, a circuit board 4, and a motor control switch 5. The blade assembly 2 is located at the front end of the housing 1. The external rotor motor 3 and the circuit board 4 are both located inside the housing 1. The external rotor motor 3 and the motor control switch 5 are both electrically connected to the circuit board 4. The motor control switch 5 is used to control the opening and closing of the external rotor motor 3.

[0030] See Figure 1 , Figure 2 , Figure 4 and Figure 5The main structure of the cutter head assembly 2 includes a fixed blade 21, a movable blade 22, a fixed blade holder 23, and a movable blade holder 24. The fixed blade 21 is fixedly connected to the fixed blade holder 23, the movable blade 22 is slidably engaged with the fixed blade 21, and the movable blade 22 is fixedly connected to the movable blade holder 24. The cutter head assembly 2 is installed to the front end of the outer casing 1 via the fixed blade holder 23. As an important component of the electric hair clipper, the specific structural composition and working principle of the cutter head assembly 2 are existing technologies and will not be described in detail here.

[0031] The outer rotor 31 of the outer rotor motor 3 is connected to the cutter head assembly 2 via a transmission connection. Specifically, in this embodiment, see [link to documentation]. Figure 1 , Figure 2 , Figures 4 to 7 The outer rotor 31 is provided with an output shaft 32 (i.e., the output shaft of the outer rotor motor 3), the output shaft 32 is provided with an eccentric wheel 33, the eccentric wheel 33 is provided with an eccentric shaft 34, the eccentric wheel 33 is eccentrically connected to the output shaft 32, the end of the eccentric wheel 33 near the outer rotor motor 3 is provided with an eccentric hole 35, the output shaft 32 and the eccentric hole 35 of the eccentric wheel 33 are interference fit, the eccentric shaft 34 is sleeved with a bearing 36, the moving tool holder 24 is provided with a transmission groove 241, the bearing 36 extends into the transmission groove 241, and the eccentric wheel 33 is connected to the moving tool holder 24 through the cooperation of the bearing 36 and the transmission groove 241. When the external rotor motor 3 is working, its external rotor 31 drives the eccentric wheel 33 to rotate through the output shaft 32. The eccentric wheel 33 further drives the eccentric shaft 34 and the bearing 36 to rotate eccentrically. Under the cooperation of the bearing 36 and the transmission groove 241, the bearing 36 drives the moving blade 22 to swing linearly relative to the fixed blade 21 through the moving blade holder 24, so that the blade assembly 2 can achieve the effect of repairing fuzz.

[0032] See Figures 1 to 4 The outer casing 1 is provided with a viewing window 6 that allows observation of the outer peripheral wall of the outer rotor 31. The outer casing 1 includes a bottom shell 11 and a front shell 12 that are adapted to each other. The bottom shell 11 and the front shell 12 are fixedly connected. The viewing window 6 is disposed on the front shell 12. In this embodiment, the viewing window 6 is made of transparent material. One end of the viewing window 6 extends to the front end of the front shell 12, and the other end of the viewing window 6 extends to the rear end of the front shell 12. Through the viewing window 6, the user can not only observe the outer rotor 31, but also observe other components inside the outer casing 1.

[0033] See Figure 1 and Figure 4A decorative cover 7 is provided on the front cover 12, covering the outside of the viewing window 6. The decorative cover 7 is detachably fixed to the front cover 12 by a magnetic connector. The magnetic connector includes a first magnet 121 provided on the front cover 12 and a second magnet 71 provided on the decorative cover 7. When the user needs to use the viewing window 6, he / she only needs to remove the decorative cover 7 from the front cover 12. When the user needs to install the decorative cover 7, the first magnet 121 and the second magnet 71 can be used to make the decorative cover 7 attach to the front cover, thus making it easy to install and remove the decorative cover 7.

[0034] See Figures 1 to 4 Inside the outer casing 1, there is also a strobe light 8 corresponding to the viewing window 6. The strobe light 8 and the outer rotor motor 3 are electrically connected to the circuit board 4. The light generated by the strobe light 8 can illuminate the outer peripheral wall of the outer rotor 31. When the outer rotor 31 is illuminated by the strobe light 8, the area of ​​its outer peripheral wall illuminated by the strobe light 8 can be observed by the user through the viewing window 6.

[0035] The strobe light 8, also known as a stroboscope, emits a light source that flashes rapidly at a set frequency, producing brief and frequent flashes. When the flash frequency is close to or synchronized with the rotation or movement speed of the object being measured, the surface condition or operating status of a high-speed moving object can be easily observed by utilizing the persistence of vision or video synchronization effect. During the production of the electric hair clipper, simply setting the flash frequency of the strobe light 8 to be close to or synchronized with the rotational speed of the outer rotor 31 allows the user to visually perceive the high-speed rotating outer rotor 31 as rotating slowly or even stationary when observing it through the viewing window 6, under the influence of the strobe light 8. This allows the user to clearly observe the surface condition of the outer rotor 31.

[0036] See Figure 2 and Figure 4 The outer casing 1 is equipped with a strobe control switch 9 corresponding to the strobe light 8. The strobe control switch 9 is electrically connected to the circuit board 4. When using the electric clipper, the user can control the strobe light 8 to turn on and off as needed through the strobe control switch 9.

[0037] See Figures 1 to 3 The strobe light 8 is located at the rear end of the external rotor motor 3. The light source of the strobe light 8 faces the front end of the housing 1. The strobe light 8 has a certain tilt angle relative to the output shaft 32 of the external rotor motor 3. The light generated by the strobe light 8 is directed towards the outer peripheral wall of the external rotor 31. When in use, the flash of the strobe light 8 is unlikely to shine into the user's eyes, thus ensuring visual effect while also providing protection for the user.

[0038] See Figures 1 to 3The outer casing 1 contains an inner casing 10 and a mounting bracket 13. The mounting bracket 13 is located at the front of the inner casing 10. The front casing 12, mounting bracket 13, inner casing 10, and bottom casing 11 are fixedly connected from top to bottom. A receiving cavity 14 is formed between the mounting bracket 13 and the inner casing 10. The outer rotor motor 3 is located in the receiving cavity 14, ensuring the stability of the outer rotor motor 3. A battery compartment 101 is formed at the rear of the inner casing 10. The battery 15 is housed in the battery compartment 101 and is electrically connected to the circuit board 4 to supply power to the electric clippers. The mounting bracket 13 has a cutout area 131 corresponding to the outer rotor 31. The cutout area 131, the viewing window 6, and the strobe light 8 are all correspondingly provided. The light generated by the strobe light 8 can shine through the cutout area 131 onto the outer peripheral wall of the outer rotor 31 and can be observed by the user through the viewing window 6.

[0039] See Figures 1 to 3 The mounting bracket 13 is provided with a slot 132, and the strobe light 8 is inserted into the slot 132 for engagement, and / or the mounting bracket 13 is provided with a fixing buckle 133, and the strobe light 8 is provided with a snap-fit ​​81 that engages with the fixing buckle 133.

[0040] In this embodiment, the rear end of the mounting bracket 13 is provided with a slot 132 and a fixing buckle 133. The strobe light 8 is inserted into the rear end of the mounting bracket 13 through the slot 132 and engaged with the fixing buckle 133 through the snap 81, so that the strobe light 8 is fixedly connected to the mounting bracket 13. Of course, in other embodiments, the mounting bracket 13 may only have a slot 132 or only have a fixing buckle 133.

[0041] See Figure 1 and Figure 2 An illumination lamp 16 is installed inside the outer casing 1. The illumination lamp 16 is electrically connected to the circuit board 4. The light emitted by the illumination lamp 16 is directed towards the front end of the outer casing 1. The front end of the outer casing 1 has a light-transmitting area 122 corresponding to the illumination lamp 16. In this embodiment, the light-transmitting area 122 is located at the front end of the outer casing 12. The front end of the viewing window 6 extends to the light-transmitting area 122. The light emitted by the illumination lamp 16 shines on the outside of the outer casing 1 through the viewing window 6 and the light-transmitting area 122. Specifically, when trimming hair, the illuminated area of ​​the illumination lamp 16 is located in front of the path of the blade assembly 2. When using the product, the user can more clearly observe the area where the hair is being trimmed through the illumination lamp 16, making it more convenient to use. Preferably, in this embodiment, the mounting bracket 13 extends to the front end of the outer casing 1, and the illumination lamp 16 is fixedly mounted on the mounting bracket 13.

[0042] See Figure 2 and Figure 4 The outer casing 1 is equipped with a lighting control switch 17 corresponding to the lighting lamp 16, and the lighting control switch 17 is electrically connected to the circuit board 4. During the use of the electric clippers, the user can control the lighting lamp 16 to turn on and off as needed through the strobe control switch 9.

[0043] The outer peripheral wall of the outer rotor 31 is provided with a pattern (not shown in the figure). When the outer rotor 31 rotates, the pattern can be observed to rotate synchronously with the outer rotor 31 through the viewing window 6. The light generated by the strobe light 8 can illuminate the pattern. Under the action of the strobe light 8, when the user observes the pattern through the viewing window 6, the pattern can also visually present a slow rotation or even a static effect, thus making it more interesting.

[0044] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
