Cutting head device and shaver

Abstract

The invention relates to a cutting head device, which is characterized in that the elastic bending parts of the first swing frame and the second swing frame are connected as one body, so that the first swing frame and the second swing frame are fixed in a housing in parallel and spaced apart; the housing is also provided with a plurality of transmission parts that make the first swing frame and the second swing frame move in parallel and opposite directions; and each transmission part is fixedly connected with the housing. The beneficial effect of the present invention is that the elastic bending parts of the first swing frame and the second swing frame are fixedly connected into one body. During the assembly or working process, the device can effectively avoid assembly misalignment or vibration displacement, reduce the amplitude, and reduce The vibration intensity improves the shave comfort of the cutter head; and a plurality of transmission parts are arranged between the first swingframe and the second swing frame, which can prevent the force transmission direction of the external driving component from changing and cause the first swing frame and the second swing frame to change. The two swing frames cannot achieve parallel swing, so that the shaving performance of the double heads is improved, and the temperature rise and vibration intensity, and the comfort of the shaverare improved.

Description

technical field [0001] The invention relates to a cutter head device, more specifically to a cutter head device and a shaver, and is mainly used in the field of shaver. Background technique [0002] The applicant applied for an invention patent named a shaver and its cutter head device on May 10, 2012. The announcement number is CN 102642213 B. This patent document actually solves the technology of reverse reciprocating motion of double cutter heads. problem, but in the production and use of the cutter head, there are also some technical defects, specifically as follows: first, the rotating part is hinged and fixed on the fixed frame by means of the third hinge shaft arranged on the fixed frame, while the fixed The frame utilizes the card slot provided in the housing, and has a relatively complex structure, which is not conducive to production assembly and increases production cost.

[0002] The applicant applied for an invention patent named a shaver and its cutter head device on May 10, 2012. The announcement number is CN 102642213 B. This patent document actually solves the technology of reverse reciprocating motion of double cutter heads. problem, but in the production and use of the cutter head, there are also some technical defects, specifically as follows: first, the rotating part is hinged and fixed on the fixed frame by means of the third hinge shaft arranged on the fixed frame, while the fixed The frame uses the card slot provided in the shell, and the structure is relatively complicated, which is not conducive to production assembly and increases the production cost

Its two, fixed frame is installed and fixed between the first swing frame and the second swing frame, although it can facilitate the hinged fixing of the rotating part like this, and it is beneficial to the first hinged hole and the second hinged hole at the two ends of the rotating part to be connected with the first hinged hole respectively. The hinge shaft and the second hinge shaft are hinged to make the two swing frames produce reverse reciprocating motion, but in actual use, the first swing frame and the second swing frame constantly rub against the fixed frame when swinging in reverse. , which greatly increases the noise of the cutter head and reduces the comfort of the shaver

Third, the first swing frame, the fixed frame and the second swing frame are all engaged with the bending grooves in the housing through the bending parts arranged at both ends. Although this engaging structure is easy to assemble, it is firmly installed. The accuracy is poor, and it is fixed by splicing the left and right shells. In the process of assembly and use, affected by processing accuracy or external factors, the first swing frame, the fixed frame and the second swing frame are prone to misalignment or vibration displacement. , while improving the noise of the shaver, it also affects the safety of the cutter head device
