Description

Technical Field

[0001] This utility model relates to the field of shaver technology, specifically to electric shavers. Background Technology

[0002] Electric shavers use an internal motor to drive the blades, achieving their shaving function. Their core functionality is now relatively mature, and manufacturers generally rely on visual design to highlight product differentiation. However, existing products often limit their visual design to static patterns or fixed decorations, lacking visual appeal and failing to effectively enhance their appeal to consumers. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an electric shaver with dynamic patterns.

[0004] To solve the above-mentioned technical problems, the present invention provides an electric shaver with dynamic patterns, including a shaver head, a motor driving the shaver head to move for shaving, the motor being an external rotor motor with a rotating outer shell, the outer shell having a pattern layer; and a light-transmitting window through which the pattern layer is exposed.

[0005] Furthermore, lighting is provided to illuminate the pattern layer.

[0006] Furthermore, the lighting is a strobe type, and there is a difference between its flashing frequency and the motor's rotation frequency.

[0007] Furthermore, the motor is a unidirectional rotating motor.

[0008] Furthermore, the motor is located on one side of the blade, and the light-transmitting window is a U-shaped opening facing the other side, surrounding the motor housing.

[0009] Furthermore, a battery is provided to power the motor, and the battery is located on the other side of the blade.

[0010] Furthermore, the motor is located in the middle of the blade, and the light-transmitting window is correspondingly opened in the middle of the blade.

[0011] Furthermore, the light-transmitting window extends laterally, and the extension is equipped with a display screen.

[0012] The rotor of the external rotor motor with a rotating outer casing is located outside the stator and is fixedly connected to the outer casing and the output shaft. When the motor is running, the rotor drives the motor output shaft to rotate, thereby driving the shaving head to move for shaving. At the same time, it drives the outer casing to rotate synchronously, and the pattern layer rotates accordingly to form a dynamic pattern that can be viewed through the light-transmitting window.

[0021] The present invention will be further described in detail below with reference to specific embodiments.

[0022] First embodiment:

[0023] Reciprocating electric shaver Figure 1 The upper part of the blade 1 is equipped with five exposed, parallel reciprocating blades 2, two of which are existing long-hair shaving heads, and three are existing short-hair shaving heads. See Figure 2 The blade body 1 has a drive motor 3 mounted on its left side and five eccentric shafts 4 arranged in parallel in the middle. A gear transmission mechanism 5 is installed between the motor 3 and the five eccentric shafts 4. The output shaft 30 of the motor 3 drives the five eccentric shafts 4 via the gear transmission mechanism 5. The five eccentric shafts 4 drive the five blade heads 2 respectively (the specific driving and connection methods are prior art and can be found in patent documents CN220680864U and CN220945457U, which will not be elaborated here). A battery 7 is mounted on the right side of the blade body 1, and a PCB board 8 is mounted at the rear. The battery 7 is powered by the PCB board 8 and connected to the motor 3. An exposed power switch 9 is mounted on the right wall of the blade body 1 and is electrically connected to the PCB board 8. When the power switch 9 is pressed, the PCB board 8 controls the battery 7 to supply power to the motor 3, enabling the motor 3 to run. The output shaft 30 of the motor 3 rotates at high speed, driving the five eccentric shafts 4 to rotate respectively via the gear transmission mechanism 5, thereby driving the five blade heads 2 to reciprocate for shaving.

[0024] See Figure 2 and Figure 3 Motor 3 is an existing external rotor motor with a rotating outer casing, including a stator support 31, which is bolted to the inside of the blade 1, and a stator 32 is mounted on it. A casing 33 is rotatably mounted on the outside of the stator support 31, and a rotor 34 is mounted on the casing 33. The output shaft 30 is fixed to the casing 33. When motor 3 is powered on, the rotor 34 drives the casing 33 and the output shaft 30 to rotate synchronously in one direction around the stator 32. The casing 33 of motor 3 has a patterned layer 35 with a wavy pattern (in other embodiments, this can be changed to other patterns, or a patterned sticker can be used as the patterned layer 35). See [link to documentation]. Figure 4 The blade 1 has a U-shaped through-slot 11 with its opening facing right on the left side. A mounting hole 1111 is formed in the upper wall 111 of the through-slot 11. The motor 3 housing 33 extends downward through the mounting hole 1111 into the through-slot 11, exposing its surface pattern layer 35. A transparent protective shell 12 is provided around the motor 3 housing 33. This protective shell 12 is installed in the through-slot 11 and serves as a light-transmitting window 13 for the blade 1. The light-transmitting window 13 is a horizontal U-shaped opening facing right, surrounding the motor 3 housing 33 and allowing light to pass through to the pattern layer 35. The pattern layer 35... Figure 5 As shown, the pattern is revealed through the light-transmitting window 13. When the motor 3 is powered on, the outer casing 33 drives the pattern layer 35 to rotate unidirectionally, forming a dynamic pattern that can be viewed through the light-transmitting window 13. See Figure 4 , Figure 6 The upper, right, and lower groove walls 111, 112, and 113 of the front and rear through groove 11 are all black light-shielding walls, which block other internal structures of the motor 3 (such as wires, batteries, etc.).

[0025] See Figure 6 The motor 3 used in the shaver operates at a high speed; in this embodiment, the motor 3 operates at a speed of up to 8000 rpm. Its outer casing 33 drives the pattern layer 35 to rotate at high speed, making the dynamic pattern difficult to discern with the naked eye. Therefore, this shaver has an illumination hole 1131 in the lower wall 113 of the front and rear through-slot 11. Ten strobe-type lights 81 are arranged circumferentially on the PCB board 8, with the lights 81 facing upwards towards the illumination hole 1131 to illuminate the pattern layer 35 on the motor 3 outer casing 33. The flashing frequency of the lights 81 is approximately 7800 times per minute, slightly lower than the motor 3's speed, producing a strobe effect. Therefore, to the user, each flash appears as a slight rotation of the pattern layer 35, creating the illusion that the pattern is slowly rotating. Since the pattern layer 35 is located within the front and rear through-slot 11, and the upper, right, and lower walls 111 of the front and rear through-slot 11 (see...)... Figure 4), 112, and 113 all use black light-shielding walls to create a local dark environment, resulting in strong contrast and good visual effect from the flickering illumination, and it is not easily affected by ambient light. In other embodiments: the flickering frequency of the lighting lamp 81 can be changed to be slightly higher than the speed of the motor 3; or a motor 3 with a lower speed can be used, and a constant-on lighting lamp 81 can be used accordingly.

[0026] Second Embodiment: The second embodiment is largely the same as the first embodiment, except that: see... Figure 2 In the second embodiment, the motor 3 has three speed settings: 5000 rpm, 6000 rpm, and 7000 rpm, and the lighting lamp 81 also has three corresponding flashing frequencies: 4500 times / minute, 5700 times / minute, and 6800 times / minute.

[0027] Pressing the power switch 9 causes the PCB board 8 to sequentially control the operation of motor 3 and lighting lamp 81.

[0028] The first press starts motor 3 and lighting lamp 81, which then run synchronously at high speed.

[0029] Press the button a second time to switch to the medium speed setting.

[0030] Press the third time to switch to low speed.

[0031] Press the fourth button to stop operation.

[0032] Different settings can achieve different shaving intensities and can also display dynamic patterns with different movement speeds.

[0033] Third embodiment:

[0034] The third embodiment is largely the same as the first embodiment, except that: see Figure 7 In the third embodiment, the motor 3 is moved to the middle of the blade 1, and the light-transmitting window 13 is correspondingly opened in the middle of the blade 1.

[0035] Fourth embodiment:

[0036] The fourth embodiment is largely the same as the third embodiment, except that: see Figure 8 In the fourth embodiment, the light-transmitting window 13 extends laterally, and the extension is equipped with a display screen 131. The PCB board 8 controls the display screen 131 to display information such as the battery power of the battery 7.

[0037] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
