Description

Technical Field

[0001] The present invention relates to the technical field of hair clippers, and in particular to a cutter head stabilizer and a hair clipper. Background Art

[0002] Existing hair clippers, such as the prior application, application number: "CN119036520A", and the Chinese patent application titled: "A cutter head sliding mechanism, a reciprocating drive mechanism and a hair clipper thereof", utilizes a corresponding driving mechanism to drive the sliding member to slide back and forth on the guide rail, and then after being connected to the movable cutter holder through the connecting shaft on the sliding member, drives the movable cutter head on the movable cutter holder to slide back and forth on one side of the fixed cutter head to achieve the hair trimming function. In order to keep the movable cutter head and the fixed cutter head in close contact, the prior art uses a torsion spring with one torsion arm connected to the fixed cutter holder, and the other torsion arm is rotatably installed on the movable cutter holder, and then utilizes the elastic force of the torsion spring to make the movable cutter head always in close contact with the fixed cutter head. For example, the patent application with application number: 202322021280.1 and the titled: "A shaver blade assembly" all adopts the above structure, which has the following disadvantages:

[0003] When the movable blade head swings back and forth on one side of the fixed blade head, the torsion spring swings with its end with the casing as the swing point and the torsion arm part of the torsion spring as the radius. This causes the following problems when the hair clipper is used: 1. The contact part between the movable blade holder, the fixed blade holder and the swing arm is easily worn and damaged due to long-term transmission; 2. The torsion arm part of the torsion spring is easily to lose its elasticity or break due to metal fatigue due to long-term swinging and twisting, which greatly affects the service life of the hair clipper and the user experience. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a cutter head stabilizer and a hair clipper, which solve the problems of the existing hair clippers that the products are easily worn and have a poor service life.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a tool head stabilizer, including a movable tool holder with a movable blade and a driving member that drives the movable tool holder to reciprocate linearly, the movable tool holder is movably connected to the driving member, and an elastic member is provided between the two to elastically tension the two.

[0006] Furthermore, the movable tool holder and the driving member are also provided with a guide limiting mechanism for limiting the movable direction of the two to the elastic tensioning direction of the elastic member.

[0007] By adopting the above technical solution and setting the guide limit mechanism, the problem of wear between the moving blade holder and the driving member due to looseness in an unfavorable direction when the hair clipper allows can be eliminated, thereby increasing the service life of the product and reducing operating noise.

[0008] Furthermore, the guide and limiting mechanism includes a limiting structure and a guiding structure, wherein the limiting structure is used to eliminate the assembly clearance between the movable tool holder and the driving member along the moving direction of the movable blade, and the guiding structure is used to guide the movable tool holder and the driving head to move in the elastic tensioning direction of the elastic member.

[0009] By adopting the above technical solution, the limiting structure limits the assembly clearance between the movable blade holder and the driving member along the moving direction of the movable blade, which can effectively avoid wear between the two when the hair clipper is running, and also make the movable blade more stable during the reciprocating motion. The guide structure cooperates with the limiting structure to effectively eliminate the undesirable swinging direction between the movable blade holder and the driving member, making the movable blade holder run more smoothly, thereby avoiding the situation where the edge of the movable blade exceeds the edge of the fixed blade due to unstable operation of the movable blade and injuring people, greatly improving the safety and quietness of the product during operation.

[0010] Furthermore, the limiting structure includes at least two mounting ears arranged on one side of the movable blade holder, and an accommodating space is formed between adjacent mounting ears. One end of the driving member is correspondingly inserted into the accommodating space to eliminate assembly clearance between the two along the movable direction of the movable blade.

[0011] By adopting the above technical solution, the installation ear is set, which facilitates the connection and combination between the movable tool holder and the driving member, and also facilitates the setting of the guide groove.

[0012] Furthermore, the guide structure includes a guide groove arranged on the mounting ear, and a guide rod is provided on the side of the driving member. When the driving member is connected to the movable tool holder, the guide rod is correspondingly slidably arranged in the guide groove.

[0013] By adopting the above technical solution, the sliding cooperation between the guide groove and the guide rod can effectively guide the moving direction between the driving member and the movable tool holder, so that the movable tool holder will only move towards the direction of the fixed blade under the elastic force of the elastic member.

[0014] Furthermore, a connecting hole is provided on the movable blade holder, and one end of the driving member is correspondingly inserted into the connecting groove to be plugged and connected with the movable blade.

[0015] By adopting the above technical solution, the two are plugged together, which facilitates the combination of the driving member and the movable tool holder.

[0016] Furthermore, the driving member includes a connector that is plug-fitted with the connecting hole, and a contact protrusion is provided on a side surface of the connector.

[0017] By adopting the above technical solution, the setting of the contact protrusions helps to reduce the contact area between the driving member and the movable tool holder, thereby reducing the wear of the components and increasing the service life of the components.

[0018] Furthermore, the connector and the inner wall of the connecting hole are respectively provided with anti-dropping protrusions along the plugging direction of the two.

[0019] By adopting the above technical solution, the anti-slip protrusion can prevent the movable knife holder and the driving member from being accidentally separated due to the elastic force of the elastic member when they are not assembled with the fixed knife head. The anti-slip protrusion keeps the movable knife holder and the driving member connected, and they are not accidentally separated due to the elastic force of the elastic member. It is arranged to facilitate the assembly between the various components of the product.

[0020] Furthermore, the limiting structure includes a guide groove and a guide rib that slides linearly along the limiting guide groove, and the guide rib is provided on any one of the adjacent sides of the movable tool holder and the driving member, and the guide groove is provided on the other side.

[0021] By adopting the above technical solution, the volume of the limiting structure can be effectively reduced through the coordination of the ribs and grooves, so that after the movable tool holder and the driving member are assembled, the volume of the product is relatively smaller.

[0022] Furthermore, the guide mechanism includes a slot provided on one side of the movable tool holder, and the driving member is provided with a dial head movable in the slot.

[0023] By adopting the above technical solution, the guiding effect on the two can also be achieved by sliding the dial head in the slot.

[0024] In a further solution, a mounting hole is provided on a side of the driving head facing the movable tool holder, and the elastic member is correspondingly hidden in the mounting hole.

[0025] By adopting the above technical solution, the installation holes are set to hide and protect the elastic parts, while optimizing the product component structure to make the product more refined and beautiful.

[0026] In a further solution, a mounting plate is provided at the end of the driving head, and the assembly groove is formed on a side surface of the mounting plate.

[0027] By adopting the above technical solution and setting the mounting plate, the contact surface between the driving member and the movable tool holder is increased, making the connection between the two more stable.

[0028] In a further solution, the elastic member is any one of a spring, a torsion spring and a compression spring.

[0029] A hair clipper comprises a casing, a fixed blade arranged at the end of the casing, a driving mechanism and a cutter head stabilizer as described above, wherein the movable blade is arranged at one side of the fixed blade, and the driving mechanism is arranged in the casing for driving the driving member to perform reciprocating linear motion.

[0030] Compared with the prior art, the advantages of the present invention are:

[0031] In the present invention, the movable blade holder provided with the movable blade is directly connected to the driving member, and the two are elastically pressed together by an elastic member, which has the following advantages:

[0032] 1. Since the movable blade is directly and movably connected to the driving member, the two are elastically tensioned by an elastic member, so that when the driving member is displaced, the three keep moving synchronously, effectively avoiding direct contact between the torsion spring and the fixed blade holder and the movable blade holder, and causing wear at the connection between the fixed blade holder and the fixed blade holder and the torsion spring, thereby extending the service life of the product and avoiding the unstable swing of the movable blade caused by the shaking gap caused by wear at the connection between the fixed blade holder and the torsion spring in traditional hair clippers. The movable blade is more stable during operation, and the movable blade will not exceed the edge of the fixed blade during reciprocating linear motion to injure people, which effectively improves the safety of the product. At the same time, the elimination of the shaking gap between the components also makes the product relatively quieter during operation.

[0033] 2. The elastic part only provides elastic tension between the movable tool holder and the driving part. The spring does not deform or torsionally move, thereby eliminating metal fatigue caused by long-term swinging and torsion of the torsion spring, effectively improving the durability of the torsion spring. At the same time, the driving part and the movable tool holder are not subject to alternating stress during product operation, which completely solves the problem of the impact of wear, breakage or failure of these parts on their service life, greatly improving the service life.

[0053] The present invention is further described in detail below with reference to the accompanying drawings.

[0054] A cutter head stabilizer, as shown in 1 and 2, is arranged on a hair clipper, which includes a moving blade holder 410 provided with a moving blade 400 and a driving member 200 driving the moving blade holder 410 to reciprocate linearly, the moving blade holder 410 is movably connected to the driving member 200, and an elastic member 300 is arranged between the two to elastically tension the two, the hair clipper is mainly composed of a housing 100, a driving mechanism, a fixed blade 110 and a fixed blade holder 120, the fixed blade 110 is installed at the end of the fixed blade holder 120, and the fixed blade 110 is installed at the end of the fixed blade holder 120, and the fixed blade 110 is installed at the end of the fixed blade holder 120. It is located at one end of the housing 100, and the movable blade 400 is arranged on one side of the fixed blade 110. The driving member 200 serves as the output end of the driving mechanism. The lower end of the driving member 200 is connected to the driving mechanism, and the upper end is connected to the movable blade holder 410. When the driving mechanism drives the movable blade holder 410 to reciprocate linearly, it drives the movable blade 400 to reciprocate linearly on one side of the fixed blade 110, so as to utilize the reciprocating movable blade 400 to cooperate with the fixed blade 110 to achieve hair trimming.

[0055] In the prior art, the function of the elastic member 300 is to make the movable blade 400 close to the fixed blade 110, and most of the existing elastic members 300 use a torsion spring 310, one end of the torsion spring 310 is mounted on the fixed blade holder 120, and the other end is mounted on the movable blade holder 410, so as to realize elastic compression between the movable blade 400 and the fixed blade 110. In this embodiment, the movable blade holder 410 on which the movable blade 400 is disposed is directly connected to the driving member 200, and the elastic member 300 is used to elastically compress the two, which has the following advantages:

[0056] 1. Since the movable blade 400 is directly and movably connected to the driving member 200, and the two are elastically tensioned by the elastic member 300, when the driving member 200 is displaced, the three keep moving synchronously, effectively avoiding the problem of direct contact between the torsion spring 310 and the fixed blade holder 120, and the wear of the connection between the fixed blade holder 120 and the torsion spring 310, thereby extending the service life of the product, and avoiding the unstable swing of the movable blade 400 caused by the shaking gap caused by the wear of the connection between the fixed blade holder 120 and the torsion spring 310 in the traditional hair clipper, so that the movable blade 400 is more stable during operation, and the movable blade 400 will not exceed the edge of the fixed blade 110 and injure people during the reciprocating linear motion, which effectively improves the safety of the product. At the same time, the elimination of the shaking gap between the components also makes the product relatively quieter during operation;

[0057] 2. In the present embodiment, the elastic member 300 only provides elastic tension between the movable tool holder 410 and the driving member 200, and the spring 320 does not deform or torsionally move, thereby eliminating the metal fatigue caused by the long-term swinging and torsion of the torsion spring 310, and effectively improving the durability of the torsion spring 310. At the same time, the driving member 200 and the movable tool holder 410 are not subjected to alternating stress during product operation, which completely solves the problem of the influence of wear, breakage or failure of these parts on the service life, and greatly improves the service life.

[0058] In this embodiment, the movable tool holder 410 and the movable blade 400 can be integrally formed or detachably connected. Preferably, they are detachably installed on one side of the movable tool holder 410. Specifically, an assembly column 412 can be provided on the movable tool holder 410, and a corresponding through hole is provided on the movable blade 400. The assembly column 412 is inserted into the through hole to realize a detachable combination of the two.

[0059] In this embodiment, the driving member 200 includes a main body 201 connected to the driving mechanism and a driving head 202 provided on the main body 201 and movably connected to the movable blade holder 410. The two are bent and arranged, which has the following advantages: a certain angle is formed between the movable blade 400 on the movable blade holder 410 and the casing 100, so that when a person holds the hair clipper, the movable blade 400 is in a position that is convenient for fitting the surface of human skin, making it convenient for the person to operate and use the hair clipper.

[0060] In order to further limit the movable direction between the movable tool holder 410 and the driving member 200 after assembly, so as to avoid wear and noise caused by adverse looseness between the movable tool holder 410 and the driving member 200 or shaking in the elastic tensioning direction of the non-elastic member 300, in this embodiment, the tool head stabilizer also includes a guide limit mechanism, which acts between the driving member 200 and the movable tool holder 410 to limit or eliminate the adverse displacement shaking in the non-elastic tensioning direction between the two.

[0061] As an embodiment of the guide and limit mechanism, it includes a guide structure and a limit structure. The limit structure is used to eliminate the assembly clearance between the movable tool holder 410 and the driving member 200 along the moving direction of the movable blade 400, and the guide mechanism is used to guide the movable tool holder 410 and the driving member 200 to move in the elastic tensioning direction of the elastic member 300.

[0062] Specifically, refer to Figure 2 , 3, 4 and 5, the limiting mechanism includes two mounting ears 415 arranged on one side of the movable tool holder 410, and an accommodating space is formed between adjacent mounting ears 415, and the corresponding driving head 202 is inserted into the accommodating space. In this way, since the driving member 200 is limited by the mounting ears 415 along the reciprocating movement direction of the movable tool holder 410, when the driving head 202 drives the movable tool holder 410 to reciprocate, the two maintain synchronous movement, avoiding unnecessary shaking and noise generated by the assembly clearance between the two during product operation, and effectively improving the product service life and noise reduction effect.

[0063] Based on the above embodiments, refer to Figure 4 The guide structure includes a guide groove 413 provided on the mounting ear 415 and opened along the elastic tensioning direction of the elastic member 300. Guide rods 230 which can slide linearly in the guide groove 413 are provided on both sides of the driving head 202. In this way, when the driving head 202 is inserted into the accommodating space, since the guide rod 230 slides in the guide groove 413, its movement trajectory is limited to the opening direction of the guide groove 413, that is, the movable tool holder 410 is only subjected to the elastic force of the elastic member 300 toward the fixed blade 110, and will not shake or deviate in an unfavorable direction, which effectively improves the wear resistance of product components and reduces the operating noise of the product.

[0064] In this embodiment, due to the sliding fit between the guide groove 413 and the guide rod 230, the movable tool holder 410 and the drive head 202 are always connected, that is, the guide structure also has an anti-detachment function, which prevents the movable tool holder 410 and the drive head 202 from accidentally disengaging after the combination of the two, thereby effectively improving the integration of product components.

[0065] In this embodiment, refer to Figure 4 and 5 The elastic member 300 can be a spring 320, a compression spring or a torsion spring 310, or other elastic member 300, as long as it can apply elastic tensioning force to the drive head 202 and the movable tool holder 410 so that the movable blade 400 can fit the fixed blade 110. This embodiment takes the torsion spring 310 as an example to illustrate the structural connection relationship between the elastic member 300 and the drive head 202 and the movable tool holder 410.

[0066] In this embodiment, refer to Figure 5 , 67, the torsion spring 310 includes a spring coil 311 and two torsion arms extending from the spring coil 311, and a certain angle is formed between the two torsion arms. The spring coil 311 is arranged on the driving head 202, and the two torsion arms are respectively connected to the main body 201 and the movable tool holder 410. For the convenience of description, the torsion arm in contact with the movable tool holder 410 is called the first torsion arm 312, and the torsion arm in contact with the driving head 202 is called the second torsion arm 313. The driving head 202 is provided with an assembly groove 211 for accommodating the spring coil 311 and a connection groove 212 for plug-in adaptation with the first torsion arm 312. The movable tool holder 410 is 0 is located at a side surface of a limiting groove 414 which cooperates with the second torsion arm 313. When the movable tool holder 410, the torsion spring 310 and the driving head 202 are combined, the spring coil 311 is correspondingly accommodated in the assembly groove 211, the end of the first torsion arm 312 is inserted in the connecting groove 212, and the end of the second torsion arm 313 is pressed against the limiting groove 414. Thus, through the elastic force of the torsion spring 310, the movable blade 400 on the movable tool holder 410 is always in contact with the fixed blade 110, which effectively ensures the tightness of the connection between the movable blade 400 and the fixed blade 110.

[0067] In this embodiment, refer to Figure 6 and 7 A connector 220 is formed at the end of the driving head 202, and a connecting hole 411 that is plug-in compatible with the connector 220 is provided on the movable tool holder 410 between the two mounting ears 415, so that when the driving head 202 and the movable tool holder 410 are plugged together, the connector 220 is inserted into the connecting hole 411 to facilitate assembly of the two. At the same time, the insertion of the connector 220 into the connecting hole 411 also facilitates guiding and limiting the movable direction between the movable tool holder 410 and the driving head 202.

[0068] Furthermore, a limiting edge 416 is provided at the bottom of the movable tool holder 410 at the connecting hole 411, so that after the driving head 202 is plugged into the connecting hole 411 through the connecting head 220, the limiting edge 416 abuts against the driving head 202, thereby limiting the plug-in stroke of the two.

[0069] In this embodiment, the connecting hole 411 is a rectangular hole, a square hole or other hole shape that passes through the movable tool holder 410. The shape of the connecting head 220 is adapted to the shape of the connecting hole 411. In order to avoid excessive displacement of the connecting head 220 along the plugging direction in the connecting hole 411, and under the action of the elastic tension of the elastic member 300, the excessive separation between the movable tool holder 410 and the driving head 202 affects the assembly of subsequent components, the top wall of the connecting hole 411 (refer to Figure 7 ) and the top of the connector 220 are provided with a limiting protrusion 250 (refer to Figure 6), so that when the elastic member 300 is elastically loaded on the driving head 202 and the movable tool holder 410, after the connecting head 220 moves a certain distance in the connecting hole 411, the two limiting protrusions 250 correspondingly abut against each other, thereby avoiding excessive displacement of the connecting head 220 in the connecting hole 411, so as to facilitate the assembly of subsequent components.

[0070] In this embodiment, refer to Figure 6 and 7 In order to reduce the contact friction between the connecting head 220 and the connecting hole 411, and to reduce the friction loss between the driving head 202 and the movable tool holder 410, contact protrusions 240 are provided on the front and rear sides of the connecting head 220. The connecting head 220 abuts against the inner wall of the connecting hole 411 through the contact protrusions 240, thereby reducing the contact surface between the components, thereby achieving the effect of reducing wear.

[0071] Reference Figure 8 and 9 As the second embodiment of the guide limit mechanism, refer to Figure 8 , wherein the limiting structure includes a guide groove 262 and a guide rib 430 that slides linearly along the guide groove 262. The guide rib 430 is set on one of the adjacent sides of the movable tool holder 410 and the driving head 202, and the guide groove 262 is set on the other. In this embodiment, the guide rib 430 is set on one side of the movable tool holder 410 and the guide groove 262 is set on one end of the driving head 202 as an example for explanation.

[0072] In this embodiment, a mounting plate 260 is provided at the end of the driving head 202, and a guide groove 262 is correspondingly opened at the center position of one side of the mounting plate 260. When the movable tool holder 410 is combined with the mounting plate 260, the guide rib 430 is correspondingly inserted into the guide groove 262. At this time, the reciprocating movement direction of the movable tool holder 410 and the mounting plate 260 is restricted, and the movable tool holder 410 and the driving head 202 can only be relatively displaced along the plug-in direction of the two. The elastic member 300 is elastically loaded between the two, and an elastic force is applied to the two, so that the movable blade 400 on the movable tool holder 410 is always attached to one side of the fixed blade 110.

[0073] In this embodiment, the elastic member 300 preferably adopts a spring 320. Correspondingly, in order to facilitate hiding of the spring 320 to improve the product aesthetics and optimize the product structure, a mounting hole 261 is opened on one side of the mounting plate 260. The corresponding spring 320 can be placed in the mounting hole 261 to hide and protect the spring 320 while improving the product aesthetics and optimizing the product volume.

[0074] In this embodiment, refer to Fig. 9A blind hole 420 may also be provided on the side of the movable tool holder 410 corresponding to the position of the spring 320 to limit the connection end between the spring 320 and the movable tool holder 410 .

[0075] In this embodiment, the guiding mechanism includes a dial head 263 arranged on both sides of the mounting plate 260, and a corresponding slot 440 is provided on one side of the movable tool holder 410. As shown in the first embodiment above, a corresponding mounting ear 415 is also provided on one side of the movable tool holder 410, and the slot 440 can be formed on the mounting ear 415 to facilitate assembly between the movable tool holder 410 and the driving head 202. In this way, the dial head 263 slides relatively in the slot 440, thereby limiting the movable direction between the movable tool holder 410 and the driving head 202 to the elastic expansion and contraction direction of the spring 320.

[0076] As a third embodiment of the guide and limit mechanism, in the above embodiment, the guide and limit mechanism is divided into two parts: a guide structure and a limit structure. It can be imagined that as long as the movement direction between the movable tool holder 410 and the drive head 202 can be limited to the elastic tensioning direction of the elastic member 300 to eliminate the movement between the movable tool holder 410 and the drive head 202 in other unfavorable directions, the guide structure and the limit structure can also be integrated together. Fig.10 and 11 , a plug-in hole 2021 can be opened at the end of the driving head 202, and a plug rod 4101 is provided on the side of the movable blade holder 410, which is movably plugged into the plug-in hole 2021 through the plug rod 4101, and the elastic member 300 is correspondingly arranged at the bottom of the plug-in hole 2021 and the end of the plug rod 4101 away from the movable blade holder 410. In this way, the plug-in cooperation of the plug rod 4101 and the plug-in hole 2021 is utilized to limit the movement direction of the movable blade holder 410 and the driving head 202, and eliminate the shaking of the two along the reciprocating linear motion direction of the movable blade 400. The structure is simpler and the assembly of components is relatively more convenient.

[0077] In this embodiment, the insertion rod 4101 and the insertion hole 2011 preferably adopt a spline fit. Fig.10 , that is, the cross section of the insertion rod 4101 is an irregular circle to prevent the two from rotating in the circumferential direction along their axes after being plugged in.

[0078] In this embodiment, in order to prevent the insertion rod 4101 from falling off and the plug-in hole 2021, the two ends of the spring 320 can be fixed at the bottom of the plug-in hole 2021 and the end of the insertion rod 4101 respectively, or anti-falling rings can be set on the outer periphery of the end of the insertion rod 4101 and the inner wall of the plug-in hole 2021, and the anti-falling rings can be used to limit the maximum displacement distance of the insertion rod 4101 in the plug-in hole 2021.

[0079] Reference Fig.12 and 13, as the power source for the linear reciprocating swing direction of the driving member, the driving mechanism is cited in the patent applied online, and only a brief description of the driving mechanism is given here. The driving mechanism includes two guide rails 540 arranged in the housing 100, and the main body 210 is slidably arranged on the guide rails 540. The guide rails 540 are driven by the power part arranged in the housing 100 to move linearly reciprocatingly along the direction of the guide rails 540. The power part includes a motor 510, an eccentric wheel 550, a connecting seat 520 and a connecting shaft 530. The output end of the motor 510 is connected to the eccentric wheel 550.
