Technical Field

[0001] The utility model relates to the technical field of electric hair clippers, in particular to a bottom blade and an electric hair clipper. Background Art

[0002] An electric hair clipper, also known as a hair clipper, is a haircutting and styling tool. It primarily consists of a blade assembly, a motor, a rotating shaft, and a power supply. The blade assembly is the most important component, consisting of a fixed blade assembly, a movable blade assembly, and a fine-tuning mechanism. The movable blade assembly is located above the fixed blade assembly, forming two rows of overlapping teeth. The fine-tuning mechanism adjusts the distance between the tooth tips of the movable and fixed blade assemblies. During use, the fixed blade remains stationary while the movable blade rapidly reciprocates back and forth, cutting hair.

[0003] The lower surface of the existing fixed blade is mostly flat except for the teeth at the front end. When the barber uses it, the hair between the fixed blade and the movable blade is trimmed. The trimmed hair below the fixed blade extends upward, which interferes with and affects the barber's smooth operation of the adjacent untrimmed area. The user experience is poor, and further improvement is needed. Utility Model Content

[0004] The utility model aims to provide a bottom blade and an electric hair clipper, which can improve the interference of the trimmed hair on the hairdresser's operation during use by designing transverse grooves and grooves on the lower surface of the bottom blade.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0008] Preferably, the lower surface of the blade body has a plurality of first grooves extending forward and backward, and all of the first grooves are respectively connected to the transverse grooves.

[0009] By adopting the above technical solution, through the provision of the first groove, when the barber pushes the electric clippers forward during the haircutting operation, the hair in the horizontal groove will be guided into the first groove, thereby avoiding interference with the haircutting operation.

[0010] Preferably, the widths of the plurality of first grooves are the same, and the plurality of first grooves are evenly arranged in the left-right direction of the blade body.

[0011] By adopting the above technical solution, the uniform arrangement of the first grooves ensures that the blade has consistent stability and usage effects in different directions, thereby improving the user's operating experience.

[0012] Preferably, the width of the first groove is greater than or equal to the tooth groove width of the tooth portion.

[0013] Preferably, the front end of the bottom of the first groove is flush with the bottom of the transverse groove, and the depth of the first groove is shallow at the front and deep at the back.

[0014] With the above technical solution, the groove design with shallow front and deep back allows hair to be discharged more smoothly, reduces blockage during hair cutting, and enhances the smoothness of trimming.

[0015] Preferably, the upper surface of the blade body further includes an inwardly recessed avoidance groove, and the avoidance groove is not connected to the tooth groove of the tooth portion.

[0016] By adopting the above technical solution, the avoidance groove design on the upper surface can reduce friction between blades, reduce heat generation, and improve the service life and stability of the blades.

[0017] Preferably, the front end of the lower surface of the blade body is an inclined surface or an arc-shaped surface with a higher front and a lower back.

[0018] Preferably, the front end of the lower surface of the blade body has a second groove, and the tooth groove of the tooth portion is connected to the transverse groove through the second groove.

[0019] Preferably, when the blade body is provided with a plurality of transverse grooves, a plurality of third grooves extending forward and backward are provided between two adjacent transverse grooves, and the third grooves are respectively connected with the two transverse grooves.

[0020] An electric hair clipper comprises a movable blade and the above-mentioned bottom blade, wherein the movable blade is located above the bottom blade and abuts against the bottom blade.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] 1. At least one transverse groove is set on the lower surface of the bottom blade. This design can better guide the trimmed hair away from the cutting area, thereby reducing interference, and has a certain combing effect on the hair, effectively improving haircutting accuracy and smooth operation;

[0023] 2. The design of shallow grooves at the front and deep grooves at the back helps to better guide hair, avoid accumulation, and improve the smoothness of trimming. In addition, since the transverse groove separates the first groove and the tooth groove, the blade has two cross-sections, which can increase heat dissipation efficiency.

[0024] 3. By providing the transverse groove and the first groove, the area of ​​contact with the scalp can be reduced, which can effectively reduce bacterial infection problems such as skin infection. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0035] Example 1

[0036] An electric hair clipper, combined with Figure 1-4As shown, it includes a bottom blade and a movable blade, wherein the movable blade is located above the bottom blade and abuts against the bottom blade.

[0037] The bottom blade of the electric hair clipper is mainly designed with grooves and transverse grooves 11 on the lower surface of the blade body 1, which effectively reduces the interference of the trimmed hair on the operation during the haircut process.

[0038] Specifically, the base blade consists of a blade body 1 and a tooth portion 2, with the tooth portion 2 located at the front end of the blade body 1. The blade body 1 includes an upper surface and a lower surface disposed opposite each other. The lower surface of the blade body 1 is provided with at least one transverse groove 11, located behind the tooth portion 2 and connected to the tooth grooves of the tooth portion 2. During the haircutting process, the transverse groove 11 effectively guides the hair within the trimming area outward, reducing interference with the hairdresser and improving the smoothness and efficiency of the operation.

[0039] A second groove 16 is formed at the front end of the lower surface of the blade body 1 , and the tooth grooves of the tooth portion 2 are connected to the transverse groove 11 through the second groove 16 .

[0040] The lower surface of the blade portion 1 also includes a plurality of first grooves 12 of the same width extending forward and backward. These first grooves 12 are connected to the transverse groove 11 and are evenly arranged in the left and right directions of the blade. The width of the first groove 12 is greater than or equal to the tooth groove width of the tooth portion 2. The bottom blade of this embodiment is U-shaped, and the lower surface of the blade portion 1 is a plane. The front end of the groove bottom of the first groove 12 is flush with the groove bottom of the transverse groove 11, so that the hair can enter the first groove 12 smoothly. The depth of the first groove 12 is designed to be shallow in the front and deep in the back, so that during the trimming process, the hair can enter the groove more easily from the front and be discharged smoothly as the groove deepens. This design can significantly reduce the phenomenon of hair getting stuck, improve the smoothness of trimming, and enhance the overall efficiency of trimming.

[0041] Those skilled in the art should understand that the first groove 12 can be a vertical groove as shown in the accompanying drawings, or it can be an arc-shaped groove, an S-shaped groove, etc. Similarly, the transverse groove 11 can also be an arc-shaped groove, an S-shaped groove, or a special-shaped transverse groove extending left and right formed by splicing multiple grooves, which can be designed according to needs.

[0042] In another embodiment, when the blade body 1 is provided with a plurality of transverse grooves 11 , a plurality of third grooves extending forward and backward are provided between two adjacent transverse grooves 11 , and the third grooves are respectively connected to the two transverse grooves 11 .

[0043] In order to reduce the friction between the blades, the upper surface of the blade body 1 is designed with an inwardly recessed escape groove 13. The escape groove 13 is not connected to the tooth groove of the blade tooth portion 2. Its main function is to provide space for the moving blade, reduce friction and heat accumulation, and improve the stability and durability of the blade during use.

[0044] To further enhance the performance of the bottom blade, the lower surface of the blade body 1 features a sloped surface 14 at the front, which is higher in front and lower in the back. This slope 14 helps uncut hair slide out smoothly during the trimming process, reducing the possibility of hair accumulation and ensuring that the barber's work in adjacent areas is not disturbed. Furthermore, the slope 14, combined with the groove, reduces friction during the trimming process, extending the blade's lifespan.

[0045] Example 2

[0046] Combine Figure 5-7 As shown, the only difference between this embodiment and embodiment 1 is that the bottom blade is square, the front end of the lower surface of the blade body 1 adopts an arc surface 15 design with a high front and a low back, and the rear end of the lower surface of the blade body 1 is concave, so that the front and back of the first groove 12 are unobstructed.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
