Fig. 4 illustrate cleaning function unit 11 on mobile converter 8 the position.An eccentric wheel 23 is connected with motor 9, is used for giving mobile converter 8 and cleaning function unit 11 with the transmission of power of motor.
Fig. 5 is the comprehensive view of the cleaning function unit of pump control module.
Fig. 6 illustrates the mutual installation relation between the different parts in the cleaning function unit 11.The control module that the work of pump 7 is controlled comprises reverse mobile converter 17, and described reverse mobile converter 17 is connected with balancer 16.The on off state of 12 pairs of pump control systems of controll block is controlled, and described controll block 12 embeds in balancer 16 and the pump rod 13.The connecting axle 15 of pump rod 13 its each ends of usefulness is connected with the right barrier film 14 of pump 7 and two barrier film arms 18 of left barrier film 41 (referring to Fig. 8) respectively.Oppositely mobile converter 17 is intended to according to the rotation of eccentric wheel 23 balancer 16, controll block 12 and pump rod 13 be moved horizontally.Oppositely the difference of the phase place of the vibration phase of mobile converter 17 and mobile converter 8 is 180 °, so that make the vibration of balancer 16, controll block 12 and pump rod 13 balance out the vibration of shaving tool 6.
As shown in Figure 7, spraying system comprises nozzle 5 and the worm gear 19 that is positioned at scavenging pump 7 exits, and described scavenging pump 7 flows to fixed head disposable razor shown in Figure 2 with cleaning fluid.Described worm gear 19 be positioned at nozzle 5 below, have spiral helicine wormwheel blade 21.Liquid stream promotes wormwheel blade 21 rotations of worm gear 19, because nozzle 5 has the connector 22 of rectangle, described connector 22 is connected with groove 20 profiles that are connected on being arranged on turbine 17, thereby realizes the rotation of 19 pairs of nozzles 5 of turbine, so that cleaning fluid 38 is injected on the fixed head disposable razor equably.
Fig. 8 is the profilograph of cleaning function unit 11, motor 9 and eccentric wheel 23.Eccentric wheel 23 is connected with the rotating shaft of motor 9, and by the rotation of described eccentric wheel upper arm 24, oppositely mobile converter 17 horizontal vibrations and balancer 16, controll block 12 and pump rod 13 correspondingly vibrate.Because the vibration of pump rod 13, the right barrier film 14 of pump 7 and left barrier film 41 begin vibration, the flexible generation suction and the pumping force of right barrier film 14 and left barrier film 41 simultaneously, thus by pump 7 cleaning fluid is imported in the fixed head disposable razor.Cleaning fluid is pumped to filter washing water inlet 2 interior and last rotations by nozzle 5 and turbine 19 and is ejected on the fixed head disposable razor.The transport path of cleaning fluid is shown with arrow 28 in the drawings.
Fig. 9 A and 9B are illustrated in shaver respectively and are in controll block 12 under the on/off situation.Shown in Fig. 9 A, when the face that pushes away 29 of controll block 12 and pump rod 13 was parallel, electric shaver was in the power connection state.Although controll block 12 is perpendicular to pump rod 13 vibration and since controll block 12 not with the face that pushes away 29 reciprocations of pump rod 13, so pump 7 is not worked.This means that pump rod 13 is not vibrated.Otherwise, shown in Fig. 9 B, when controll block 12 perpendicular to pump rod 13 push away face 29 time, electric shaver is in off-state.In controll block 12 vibrations, because the reciprocation of the face that pushes away 29 of controll block 12 and pump rod 13, thereby connecting axle 15 is by working the right barrier film 14 of pump 7 and left barrier film 41 to the right barrier film 14 of pump 7 and " pushing away/draw " of left barrier film 41.The direction of vibration of controll block is shown with arrow 36 in the drawings.
Figure 10 A, B, C are illustrated in the work that electric shaver is in the system under " breaking " situation with profile.Shown in Figure 10 A, eccentric wheel upper arm 24 is connected with mobile converter 8 with reverse mobile converter 17 respectively with eccentric wheel underarm 25.Controll block 12 is in level, and this point means that electric shaver is in disconnected state.Figure 10 B and 10C illustrate working condition.Because the center line C2 of upper arm 24 and the center line C1 off center line C of eccentric wheel underarm 25 during rotation, oppositely mobile converter 17 and mobile converter 8 are mutually oppositely.Thereby when eccentric wheel 23 rotations, two arms are oppositely around center line C rotation.Because the center line C2 of eccentric wheel upper arm 24 is always around center line C rotation, the right barrier film 14 of pump 7 and left barrier film 41 pushed away/draw effect so the off-centre that continues moves to vibrate and to produce based on the horizontal vibration of pump control module reverse mobile converter 17.And the rotation of eccentric wheel underarm 25 will make vibratory transducer 8 vibration, thereby shaving tool 6 is also vibrated.Because the amount of the moment of inertia of mobile converter 8 and reverse mobile converter 17 equates, so can balance out vibration mutually, reaches the effect of vibration damping.With regard to the work of scavenging pump, shown in the arrow among Figure 10 B 31, when center line C2 was offset to the left, the left barrier film 41 of the scavenging pump 7 on the left side was compressed.This means that because check valve B27 (referring to Fig. 8) is closed and check valve A26 (referring to Fig. 8) opens, cleaning fluid is cleaned pump 7 and pumps.In contrast, as shown in arrow 30, the right barrier film 14 of the scavenging pump 7 on right side stretches.This is because center line C2 departs from the right barrier film 14 events of the scavenging pump 7 on right side.Simultaneously owing to check valve B27 (referring to Fig. 8) opens and check valve A26 (referring to Fig. 8) closure, so cleaning fluid is inhaled in the pump 7.Adopt the mode of this mutual reversal of vibrations of reverse mobile converter 17 and mobile converter 8 can reduce vibration and noise in the electric shaver cleaning process to greatest extent.
As shown in figure 11, in the circuit of electric shaver of the present invention, be provided with two derailing switches, one of them derailing switch is the switch that shaves, and is used for the function that shaves is carried out on/off control, and the described switch that shaves is mechanically controlled (referring to Fig. 3) to the orientation of controll block 12.According to the reciprocation of shave switch and controll block 12, when being in " leading to " state at electric shaver, scavenging pump 7 disconnects with mobile converter 8 machineries; And when being in " breaking " state at electric shaver, controll block 12 is with scavenging pump 7 and mobile converter 8 mechanical connections.Another derailing switch is a cleaning switch, and described cleaning switch is implemented on/off control to cleaning process.Described cleaning switch can be electromagnetic switch, semiconductor switch or common mechanical switch.Adopted semiconductor switch 40 in the present embodiment.Electromagnetic device, for example hall device or reed switch etc. are used for electronic clock 34 and bistable multivibrator 35 are triggered.Adopted hall device 32 in the present embodiment.Therefore, in case magnet or the magnetic material 33 approaching hall devices 32 that are arranged on the electric shaver, hall device 32 will be activated, to analog signal of amplifier 42 outputs.Schmidt trigger 43 becomes data signal with the analog signal conversion through amplifying.Magnetic field intensity externally is during greater than predetermined threshold value, and Schmidt trigger 43 will be exported a "Yes" signal.Described "Yes" signal triggers electronic clock 34, begins the cleaning process timing.
As shown in the table of Figure 12, because set (S) port of bistable multivibrator 35 is by the "Yes" signal activation, but reseting port (R) is not activated, so the output of bistable multivibrator 35 (O) is the "Yes" signal.The "Yes" signal that semiconductor switching device 40 is exported by bistable multivibrator 35 is connected " ON ".Therefore, motor 9 and scavenging pump 7 are started working, and start cleaning process.After time, electronic clock 34 is to "Yes" signal of reseting port (R) output of bistable multivibrator 35 in predefined procedure.At this moment, the output of bistable multivibrator 35 is "No" signals, thereby makes semiconductor switching device 40 be disconnected " OFF ".Therefore motor 9 and scavenging pump 7 are disconnected, and cleaning process finishes.In cleaning process, in case magnet or magnetic material 33 are moved apart hall device 32, hall device 32 will send a "No" signal to electronic clock 34 and bistable multivibrator 35 by amplifier 42 and Schmidt trigger 43.At this moment, electronic clock 34 is resetted by this "No" signal and set port (S) and reseting port (R) all are reset to "No".Thereby make semiconductor switching device 40 disconnect " OFF ", finish cleaning process.
Figure 13 illustrates the basic structure of rinse bath 37.Cleaning fluid 38 leaves in and cleans in the liquid bath 37.When electric shaver 1 beginning washing and cleaning operation, electric shaver 1 is placed on and cleans in the liquid bath 37, and the built-in scavenging pump 7 of electric shaver 1 provides pipe 39 to be pumped into cleaning fluid 38 through cleaning fluid input port 2 from being arranged on cleaning fluid on the rinse bath 37.At last, the cleaning fluid 38 after using is collected in the rinse bath 37 again and recycles.
