The specific embodiment
The hair cutter of as shown in Figure 1 and entirety by reference numeral 1 expression or shaver comprise that a qualification seizes the body 2 of holding district 3 and a cutting head 4 being housed in its underpart.Shaver 1 also comprises at least one lining, and according to shown in example comprise two sectional naves 5 and 6, each lining is used for alternately being installed in the lower end of body 2, and is as shown in Figure 2.The body 2 of shaver comprises the tenon 2 among some eyelet O that are embedded in the flexible tongue L end that is arranged at each lining 5,6
1The bottom of each lining 5,6 limits an abutment surface 7 that makes shaver be close to or contact with user or people's skin, utilizes shaver 1 cutting user's of the present invention hair or beard.The abutment surface 7 that it should be noted that lining 5,6 is to rear curved, so that the oscillating motion of shaver, thereby realize the degradation cutting.
In order to regulate the cutting-height H that is confirmed by the distance between abutment surface 7 and the cutting head 4, a principal character is contained in cutting head 4 on the body 2 according to the present invention, makes its relative body 2 and the lining 5 or 6 abutment surface 7 translations that are contained on the body 2.For this reason, according to the present invention, the cutting cube of a cutting head 4 and a slip in body 2 or cutting balladeur train 10 are rigidly connected.As shown in Figure 3, utilize rail guidance cutting balladeur train 10 translations of balladeur train 10 both sides to move, each guide rail is by being located in the balladeur train 10 and being embedded in and body 2 rigidly connected tongue pieces 10
2On straight-line groove 10
1Constitute.This installation can make cutting balladeur train 10 that moving by a relatively large margin can be arranged, and very big guiding accuracy is arranged again simultaneously, and because the rigidity that guide rail provides, so the danger that is not blocked.According to the present invention, cutting balladeur train 10 also has the motor that is used to drive cutting head 4.Because therefore cutting head and be well known to those skilled in the art by the embodiment of motor driven cutting head does not belong to the object of the invention, will not describe here.
In order to guarantee to cut the translation of balladeur train 10 with respect to body 2, shaver 1 comprises the parts 12 of regulating cutting-height H, and height H guarantees moving of cutting balladeur train 10.According to shown in example, cutting-height is regulated parts 12 and is comprised endless screw system, the bolt 13 and the body 2 of this system connect together, and are driven by the starting motor of regulating parts 12 14 and rotate.Motor 14 and decelerator (not shown) thereof are fixed on the body 2 through hold-down screw.Thereby bolt 13 cooperates with nut 15, and nut 15 is rigidly connected with cutting balladeur train 10.
The drive motor 11 that the battery A of the body 2 through being arranged in shaver 1 gives cutting head 4 and cutting-height are regulated starting motor 14 power supplies of parts 12.Thereby the control of the operation of drive motor 11 operation/shutdown switch 17 of receiving to touch on the top of body 1.The operation of starting motor 14 receives the control of reverser 18; Reverser 18 can perhaps move up according to the moving direction of required cutting head 4; Perhaps move down, like following appearance, the centre position of reverser 18 is equivalent to the stop position of starting motor 14.
The shaver 1 that constitutes like this moves in such a way.When cutting-height was regulated in hope, the user made reverser 18 actions, for example makes it downward, to reduce cutting-height H.Cutting head 4 moves to the low level of the minimum possibility cutting-height that is equivalent to employed lining 5 shown in Figure 4 from a high position that is equivalent to maximum cutting-height as shown in Figure 2.When the user unclamped the pressure that is applied on the switch 18, motor 14 stopped, and made cutting head slack in the position that it has arrived.It is pointed out that and use worm screw 13 to guarantee that the moving of cutting balladeur train 10 that has cutting head 4 can regulate cutting-height H continuously, subtly.
In case reach required height, the user can be through the operation of switch 17 control cutting heads 14.It should be noted that and therefore can not change the adjusting of cutting-height because the form of lining 5 and the position of cutting head 4 have no power to be applied on the cutting head between the operating period.In fact, cutting head can not be touched, and the rigidity of comb is enough to tolerance, because there be not beating of relative body 2, comb is fixed on the body 2 as retainer all the time.Therefore, in order to forbid that cutting head 4 when moving any out of season translation takes place and moves, so shaver of the present invention is designed so that switch 17 reverser 18 when run location is inoperative.On the contrary, when starting motor 14 operations, can firing switch 17.
Therefore, shaver 1 can be realized the reliable adjustment of cutting-height H with simple mode, and cutting-height H will depend on minimum cut height and the mobile range of cutting head 4 between its low level and a high position that lining allows.Therefore, be under the situation of first lining 5 of 5mm and the cutting head 4 that mobile range is 15mm at the minimum cut height, can regulate cutting-height meticulous in the scope of 5mm-20mm, continuously.In addition, it is 1.5mm that second lining 6 can be designed as the minimum cut height, and the adjustable range that therefore allows is 1.5mm-16.5mm.
For the ease of regulating, shaver 1 of the present invention preferably is equipped with the parts 20 that show cutting-height.According to shown in example, display unit 20 comprises window 21 that connects together with lining 5 or 6 and the vernier 22 that is connected with cutting head 4, here vernier 22 be engraved in the cutting balladeur train 10 outer surface on.Therefore, when the lining that has window 21 5 is in 1 last time of shaver, can see vernier 22, and cutting-height is represented in its position.Therefore window 21 can indication matches with numeral with the scale that shows the cutting-height value scope that lining 5 is allowed.If each lining 5 and 6 all has window 21 and numeral indication 23, then need not use complicated lining recognition system to realize the information that display unit provides.
According to the embodiment relevant with Fig. 1-4 that the front is described, drive motor 11 is different with starting motor 14.But, this embodiment and nonessential, so Fig. 5 representes an embodiment, according to embodiment shown in Figure 5, same motor 25 or guarantee to drive cutting head 4 perhaps guarantees to drive moving-member 12.For this reason, motor 25 is carried by selection and moving-member 26, can in body 2, translation move.The end of the driving shaft 27 of motor 25 has mechanical attachment system 28 and 29, is used for alternately driving cutting-height adjusting parts 12 or cutting head 4 according to the position of alternative pack 26.In addition, the operation of motor 25 is positioned at the control of the switch 30 on the body 2 of shaver 1.
Fig. 6 representes another the relevant modification of shaver with Fig. 1-3 description.According to this modification, shaver comprises follow-up unit 40, and said follow-up unit 40 moves cutting head 4 when moving on skin on the surface 7 of the skin that reclines.Therefore, follow-up unit 40 comprises calculating and the control module 41 that is connected with trundle 42, and trundle 42 is used for contacting with skin, so the rotation of trundle can be indicated the travel distance on skin.Thereby calculating and control module 41 convert this distance into cutting head 4 proportional and move, and control starting motor 14, so that cutting head 4 is moved, thereby realizes the degradation cutting automatically.Therefore do not have console switch 18 just can change cutting-height, and switch 17 is in run location.
Fig. 7 representes another the relevant modification of shaver with Fig. 1-3 description.In a single day according to this modification, cutting head 4 is dismountable, thereby takes out lining 5, cutting head 4 just is easy to and cuts balladeur train 10 and breaks away from.Taking out cutting head 4 is convenient to clean greatly.In this implements the scope of modification, shaver also can with can combine better with the second detachable cutting head 4 ' that first cutting head 4 exchanges.Second cutting head 4 ' is preferably designed as and guarantees to strike off chaeta or hair, and first cutting head 4 is designed to guarantee to prune chaeta or hair.
Certainly, can in the scope of claims, carry out any other various modifications to hair cutter or shaver 1.
