Detailed Implementation
[0028] The present invention will now be described in further detail with reference to the accompanying drawings.
[0029] Please see Figure 1-6 As shown, this embodiment provides a novel blade structure for a side-mounted razor, including: a housing 1.
[0030] like Figure 1 , 2 As shown, in this embodiment, a motor 2 is installed near the front end inside the outer casing 1. An output rod 3 is provided on the front of the motor 2, and an output gear 4 is sleeved on the front end of the output rod 3. A gear ring 5 is sleeved on the outside of the output gear 4. A rotating shaft 8 is provided on the front of the gear ring 5. A slot is opened on the surface of the rotating shaft 8, and a blade 9 is inserted into the slot. A control switch 10 is provided near the back end inside the outer casing 1. A copper sheet 11 is provided between the control switch 10 and the motor 2. The control switch 10 has a battery installed inside. The blade 9 at the front end is sleeved on the slot of the rotating shaft 8. When the control switch 10 on the back end is pressed, the entire shaver extends into the outer casing 1 and presses the copper sheet 11, so that the copper sheet 11 at the bottom of the motor 2 and the battery in the control switch 10 form a current circuit to power the motor 2. The front output rod 3 drives the output gear 4 to rotate. The output gear 4 is sleeved in the gear ring 5, which drives the gear ring 5 to finally drive the rotating shaft 8 to rotate. The blade 9 on the rotating shaft 8 rotates to shave.
[0031] like Figure 2 , 3 As shown, in this embodiment, a spring pad 6 is provided on the back of the toothed ring 5, and a spring 7 is provided on the back of the spring pad 6. The toothed ring 5 is thicker than the output gear 4. The gear 4 is embedded in a longer tooth groove, and the toothed ring 5 can move forward and backward at the front end of the housing 1. The meshing of the teeth does not affect the synchronous rotation of the two. The spring 7 at the end is supported on the spring pad 6 at one end and supported at the opening of the output rod 3 of the housing 1 at the other end. The toothed ring 5 presses the spring 7 inward. The front end has a limit block to prevent the toothed ring 5 from falling off, so that the toothed ring 5 has a certain rebound ability, allowing the front blade 9 to better fit the face and achieve the best shaving effect.
[0032] like Figure 2 , 3As shown, the front end of the spring pad 6 in this embodiment is provided with a convex circle; wherein, the spring pad 6 does not rotate with the toothed ring 5, and the convex circle separates the spring pad 6 and the toothed ring 5, reducing the contact area between the two, and the arc area reduces the friction between the two, thereby reducing the wear of the components and extending their service life.
[0033] like Figure 2 , 3 As shown, in this embodiment, spring 7 has spring posts at both ends located on the back of the outer shell 1 and the spring pad 6. The spring 7 is fixed by being sleeved on the spring posts at both ends, and the spring pad 6 has a gap in the middle between the spring posts at both ends. The spring 7 further restricts the spring pad 6 from rotating.
[0034] like Figure 4 As shown, the blade 9 in this embodiment is a quarter-circular arc shape; the arc-shaped blade 9 can better conform to the face during movement compared to a flat blade, thus making more effective use of the blade and shaving more thoroughly.
[0035] like Figure 4-6 As shown, the blade 9 in the slot of the rotating shaft 8 in this embodiment can be replaced with blade 12. This invention designs two blade structures. Blade 9 is a quarter-circle arc, which is inserted into the slot of the rotating shaft 8 and fixed by an extension rod along its edge. Four blades 9 are inserted into the corresponding four slots, with a 45-degree chamfer on both sides at the center position to facilitate the fitting and fixing of the four blades 9. The other blade 12 is a semi-circle arc, with a mating groove at the center position. The two blades 12 have the same shape but opposite mating groove positions. The two mating grooves are joined at the center position, making the front arc blade edge flush, and the whole assembly is inserted into the slot of the rotating shaft 8 for fixing. Blade 9 does not require grooving and has minimal overall deformation, while blade 12 has fewer blades and a more stable overall installation.
[0036] Working principle: The battery inside the casing connects to the copper plate 11 via the control switch 10 to power the motor 2. The output rod 3 of the motor 2 drives the gear ring 5 to rotate via the output gear 4, which in turn drives the blades on the front rotating shaft 8 to rotate for shaving. Different types of arc-shaped blades are installed on the rotating shaft 8 as needed. During shaving, the gear ring 5 pushes the spring pad 6, and the spring pad 6 compresses the spring 7, allowing the gear ring 5 to be adjusted back and forth, so that it can fit the face more closely during shaving.
[0037] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
