Detailed Description
The technical solution of the present invention will be described below with reference to the accompanying drawings of the present invention.
The utility model discloses a tool bit structure, it includes interior cutter unit spare 1 and with interior cutter unit spare 1 complex outer cutter unit spare 2, interior cutter unit spare 1 is articulated with outer cutter unit spare 2 promptly, and can be by rotary device's output drive [ the attached drawing does not draw, for example by the rotatory output drive ] of motor or razor, the rotatory function of shaving that realizes of relative outer cutter unit spare 2.
Preferably, the inner cutter assembly 1 includes a cutter head 12, the cutter head 12 is fixedly provided with a central shaft 121, the outer cutter assembly 2 includes a cutter net rack 23 and a fixing rack 24, inner cavities of the fixing rack 24 and the cutter net rack 23 are both cylindrical, the fixing rack 24 is embedded into the cutter net rack 23, the center of the fixing rack 24 is provided with a central sleeve 241, the central shaft 121 is embedded into the central sleeve 241, so that the inner cutter assembly 1 is hinged to the outer cutter assembly 2, and the output end of the rotating device is inserted into the central shaft 121, i.e., the inner cutter assembly 1 can be driven. The concentricity of the inner cutter component 1 and the outer cutter component 2 can be ensured, so that the inner cutter component 1 is more stable and noise is reduced when rotating relative to the outer cutter component 2.
Normally, the bottom end of the knife net side 212 extends outwards, the knife net frame 23 and the backing ring 25 clamp the bottom end of the knife net side 212, and the fixing frame 24 abuts against the bottom end of the backing ring 25.
The inner cutter component 1 is provided with an inner cutter 11; the outer cutter assembly 2 is provided with a cutter mesh 21, the top end of the inner cutter 11 is attached to the inner wall of a cutter mesh end face 211 (namely, the end face of the cutter mesh 21), and an included angle is formed between the cutter mesh end face 211 and the cutter mesh side face 212. Typically, the angle between the screen end face 211 and the screen side face 212 is one-hundred-seven degrees to ninety degrees.
The joint between the top end of the inner cutter 11 and the outer side surface of the inner cutter 11 (i.e. the side surface of the inner cutter 11 away from the axis of the cutter head 12) is a long beard angle 111.
The knife net 21 is provided with long beard holes 22, and the long beard holes 22 extend from a knife net end face 211 (i.e. the end face of the knife net 21) to a knife net side face 212 (i.e. the side face of the knife net 21).
A gap is arranged between the outer side surface of the inner cutter 11 and the inner wall of the cutter mesh side surface 212.
The long beard angle 111 exceeds the inner end of the long beard hole 22 (i.e. the end of the long beard hole 22 close to the axis of the cutter head 12) and is higher than the bottom end of the long beard hole 22 (i.e. the end below the long beard hole 22).
Preferably, the length of the long hair angle 111 beyond the inner end of the long hair hole 22 is that the long hair angle exceeds length a; the height of the long hair angle 111 above the bottom end of the long hair hole 22 is the long hair angle exceeding height B, so that the long hair angle exceeding length A is smaller than the long hair angle exceeding height B. After the long beard W enters the long beard hole 22, the long beard W is relatively vertical (i.e. the included angle between the long beard W and the axial center of the cutter head 12 is smaller), and is easily cut by the long beard angle 111, so that the long beard W is easily cut.
The utility model discloses a theory of operation of tool bit structure does: when long whiskers W are removed, the long whiskers W pass through the joint of the knife net end face 211 and the knife net side face 212, and then enter the long whisker hole 22 through the guiding function of the long whisker hole 22 after the short length of the long whiskers W enters the joint of the knife net end face 211 and the knife net side face 212, that is, the long whiskers W easily enter the long whisker hole 22.
After the long hair W passes through the long hair hole 22, the inner end of the long hair hole 22 and the bottom end of the long hair hole 22 are respectively contacted with the long hair W, at this time, as shown in FIG. 7, the long hair W is bent under the restriction of the inner end of the long hair hole 22 and the bottom end of the long hair hole 22, and the long hair W is cut off when the long hair angle 111 rotates to pass through the long hair W.
It can be seen from the above that, the utility model discloses a tool bit structure can get into long palpus hole 22 more easily by long palpus W to cut off long palpus W more easily.
Preferably, the long hair hole 22 passes through the axial center of the blade net 21 in a plan view. When the razor is held to push the blade structure, the long beard W is usually along the long beard hole 22, so that the long beard W can enter the long beard hole 22 easily.
Preferably, there are at least two inner knives 11, the inner knives 11 comprise a long knife 118 and a short knife 119, and the length of the long knife 118 [ i.e. the long knife length C ] is greater than the length of the short knife 119 [ i.e. the short knife length D ]. Typically, there are six inner blades 11, three long blades 118 and three short blades 119. The long knife 118 and the short knife 119 are staggered (staggered around the rotation direction), the stroke of the inner knife 11 is longer during shaving (namely the rotation angle before the inner knife contacts with beard is extremely large), and the shaving effect is ensured.
Preferably, the long knives 118 and the short knives 119 are arranged at intervals [ i.e., the long knives 118, the short knives 119, the long knives 118, and the short knives 119 are arranged in sequence around the axis of the cutter head 12 ], and the long knives 118 are flush with the outer side surfaces of the short knives 119 [ i.e., the distance from the outer side surfaces of the long knives 118 to the axis of the cutter head 12, and the distance from the outer side surfaces of the short knives 119 to the axis of the cutter head 12 are equal ]. In general, shaving is performed by contacting the short beard with the end face 211 of the cutter net close to the axial center of the cutter head 12, so as to pick the short beard, and the short beard is hard and generally needs a larger stroke of the inner cutter 11 to pick the short beard, so as to ensure that the short beard can be cut off. The effect of picking short beard can be ensured.
Typically, the junction of the foil end face 211 and the foil side face 212 is rounded; the joint between the knife net end surface 211 and the knife net side surface 212 is not sharp, and the touch feeling of the knife net 21 when contacting with the skin can be ensured.
