[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0032] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.
[0033] See Figure 1 and Figure 2 , a reciprocating shaver, which is composed of a cutter head 100 and a fuselage 200, and the cutter head 100 is detachably connected to the fuselage 200. At the same time, an openable protective cover 300 is provided on the cutter head. By setting a positioning groove 310 on the surface of the cover of the cutter head and a positioning protrusion on the protective cover 300 that is engaged with the positioning groove, the protective cover is fixed by the groove structure to prevent the bump structure from irritating the skin. The cooperation between the positioning protrusion and the bottom groove can fix the protective cover well and will not irritate the skin, which is consistent with the smooth and round comfortable touch shape of the fuselage body.
[0034] Since some deformation will occur when the protective cover is covered, in an embodiment of the present invention, the protective cover 300 is made of plastic material and has elasticity for repeated use.
[0035] As another embodiment, the connection method between the protective cover and the cutter head can adopt a magnetic attraction fit, that is, by fixing a magnet inside the protective cover and using the metal of the cutter head assembly to adsorb the magnet, the fixed connection between the protective cover and the cutter head is realized.
[0036] At the same time, the protective cover is mainly used to protect the cutter head assembly of the cutter head.
[0037] The cutter head and the body are detachably connected, which makes it easy to clean the beard residue cut off by the cutter head.
[0038] An iron plate 400 or iron sheet is arranged at the bottom of the hair collection chamber formed at the upper end of the body, which can cover the exposed structures such as the screw holes at the bottom. The iron plate 400 is arranged at the upper end of the body, and the magnet 130 is arranged in the cutter head. When cleaning the inside of the cutter head, it is only necessary to overcome the attraction between the magnet 130 and the iron plate 400 to remove the cutter head. When installing, it is directly adsorbed, which is convenient for loading and unloading and not easy to fail. This solution simplifies the appearance structure, no buttons are exposed, and increases the life of the cutter head.
[0039] like Figure 3 As shown, the body 200 is composed of an outer shell and an inner shell.
[0040] The outer shell 210 has a cavity 211 inside and an opening at the upper end. A plurality of reinforcing ribs are arranged around the inner wall of the outer shell to support and limit the inner shell and ensure that its position inside the outer shell remains unchanged. At the same time, a charging port for exposing the charging interface is arranged at the bottom of the outer shell, and a sealing ring is arranged around the outer wall to achieve sealing at this position.
[0041] The liner 700 includes a frame 710 and a transmission mechanism 720 fixed on the frame 710. The outer contour of the upper end of the frame 710 is matched with the inner contour of the outer shell 210, and the entire liner 700 can be loaded into the cavity 211 through the opening.
[0042] like Figure 5 and Figure 7 As shown, the transmission mechanism includes a motor 721 and a transmission assembly 722, and the transmission assembly is composed of an eccentric piece and a swing frame, wherein a plurality of swing frames can be driven by a multi-eccentric shaft, or two swing frames arranged side by side can be used as in the present embodiment, the motor is linked to one of the swing frames through an eccentric piece, and the eccentric piece is used to convert the rotation of the motor shaft into a linear reciprocating movement of the swing frame, the two swing frames are connected by a connecting rod, and the connecting rod is used to drive the other swing frame to move in the opposite direction, wherein the structure connecting the connecting rod and the swing frame is a design of a guide column and a strip hole.
[0043] like Figure 4As shown, at least two connecting columns 212 are fixedly arranged on the inner wall of the outer shell 210 along the moving direction of the inner container 700, and a threaded hole 213 is axially arranged through the connecting column 212. A fixing hole 760 adapted to the threaded hole 213 of the connecting column 212 is arranged on the frame 710. The inner container 700 placed in the cavity 211 is fixedly connected to the outer shell 210 by screws 800, and the screws 800 pass through the fixing holes 760 to form a threaded connection with the threaded holes 213.
[0044] Adopting the fixing method of screws and threaded holes, it can realize a detachable design, which is convenient for subsequent rework or maintenance. At the same time, there is a space below the fixing hole of the frame to avoid the connecting column, which can also play a guiding role during installation.
[0045] At the same time, there are two connecting columns, which are asymmetrically arranged on both sides of the inner wall of the outer shell, thus playing a foolproof design to avoid incorrect installation.
[0046] The connecting column is a cylinder, which is integrally formed on the inner wall of the outer shell through a reinforcing rib, and its processing is more convenient and can be processed in one go.
[0047] See Figure 3 , an upper cover body 900 fixedly connected thereto is arranged at the upper end of the frame 710. The upper cover body and the frame are fixedly connected by screws, that is, the upper cover body is provided with a first screw hole and a second screw hole, and an installation space is formed between the two. A motor installation groove is arranged in the center of the frame, an interface board installation groove is arranged at the lower end of the motor installation groove, and arc-shaped installation grooves are respectively arranged on both sides of the motor installation groove.
[0048] Among them, the charging interface board 760 is arranged perpendicular to the control board 750, and the two are electrically connected by pin welding. When the control board is fixedly installed above the motor installation groove, the charging interface board is placed in the interface board installation groove.
[0049] The arc-shaped installation grooves are respectively used to install the battery 730 and the counterweight 740 to achieve weight balance on both sides and ensure the overall feel of the shaver.
[0050] The motor is arranged in the motor installation groove and is fixedly connected by screws to ensure that its position does not change due to vibration in the motor installation groove. At the same time, a shock-absorbing block is arranged between the motor and the bottom of the motor installation groove to avoid the transmission of vibration and the vibration feeling during holding.
[0051] The transmission component 722 is arranged in the installation space, and the transmission shaft of the transmission component 722 passes through the upper cover body to form a linkage with the cutter head component in the cutter head. That is, both ends of the swing frame are fixed to the frame by means of press riveting, thermal riveting, and screws to realize the position fixation of the swing frame, and the reciprocating movement is realized by using the stroke variable of the elastic piece of the swing frame itself.
[0052] The side wall of the motor mounting groove extends upward to form a buckle 770 for fixing the control board, and the control board 750 is restricted by the buckle 770 to cover the motor mounting groove. This mounting method is simple and convenient for subsequent disassembly.
[0053] As Figure 5 shown, the control board 750 adopted in this application is provided with a display device and a switch assembly. The switch assembly is placed at the switch hole of the housing, and the display device adopted in this embodiment uses a light display method, that is, by setting a light-transmitting plate and using light-emitting diodes inside the light-transmitting plate to realize the display of numbers or symbols on the light-transmitting plate.
[0054] As Figure 6 shown, the display device in this application uses a digital display, and directly uses a digital tube to realize the display of numbers or symbols.
[0055] At the same time, the switch assembly can be in the form of a tactile switch or a touch switch, etc., and can be set according to requirements.
[0056] A sealing assembly 1000 is provided at the connection between the upper cover body 900 and the housing 210. The sealing assembly is used to seal the connection between the upper cover body and the housing, and at the same time, it also seals the first screw hole and the second screw hole on the upper cover body.
[0057] See Figure 8 and Figure 9 As shown, the sealing assembly 1000 includes a sealing ring 1010 and a first screw hole sealing ring 1020 and a second screw hole sealing ring 1030 integrally formed with the sealing ring 1010. The first screw hole sealing ring 1020 is arranged at the first screw hole on the upper surface of the upper cover body, and the second screw hole sealing ring 1030 is arranged at the second screw hole on the upper surface of the upper cover body.
[0058] The upper surface of the upper cover body is provided with an arc-shaped glue inlet runner communicating with the first screw hole. The glue remaining in the arc-shaped glue inlet runner is formed into an arc-shaped sealing member 1040. When the upper cover body and the sealing assembly are integrally formed, the hot-melt glue enters the first screw hole along the arc-shaped glue inlet runner and enters the injection channel of the sealing ring, and then reaches the second screw hole, thereby completing the forming of the two. The design of the arc-shaped glue inlet runner can prevent the glue in the cooled state from entering the first screw hole, thereby affecting the sealing performance of the sealing assembly.
[0059] As Figure 1 and Figure 10As shown, the cutter head 100 includes a round head cutter group 500 and a cutting cutter group 600. The two cutter groups are arranged side by side and are fixedly supported by a cutter head seat 120 in the housing 110. At the same time, two mounting grooves for installing magnets are provided at the bottom of the cutter head seat, and the magnets are embedded in the mounting grooves.
[0060] As Figure 11 shown, the cutting cutter group 600 includes a cutter holder 610, an outer cutter 620 fixedly installed on the cutter holder 610, and a moving cutter group 640 installed in the working groove of the cutter holder and driven by a drive shaft to reciprocate along its length direction. A number of guide members 630 are arranged in an array on the edge of the cutter holder. The guide members are distributed in a comb-like shape on the edge of the cutter holder, and at the same time, their tops are round, spherical or have a smooth arc, which serves to guide the beards to be cut into this cutter group. There are no sharp corners on the outer surface of the guide members, especially the top is designed as an arc surface, which improves the comfort and smoothness of skin contact.
[0061] The guide members 630 are arranged in a row along the length direction on the top of one or both side walls of the cutter holder 610, and are adapted to the cutting range of the cutting cutter head, so as to facilitate guiding the beards to be cut into the cutting range.
[0062] As Figure 12 shown, a bayonet that can be fixedly connected to the tool holder is fixedly provided at the bottom of the outer cutter, and it is clamped in the working groove of the cutter holder. The moving cutter group is composed of a moving cutter and a transmission member 640. The transmission member is clamped with the moving cutter, and a linkage groove linked with the drive shaft is provided at the bottom of the transmission member. At the same time, the moving cutter group is supported by a tool holder 650 in the working groove of the cutter holder, and a spring is provided between the moving cutter group and the tool holder, which plays a floating effect. At the same time, the tool holder is clamped and matched with the cutter holder.
[0063] The embodiments should not be regarded as limitations of the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
