Detailed Description

In order to explain the technical contents and structural features of the present application in detail, the following description is made with reference to the embodiments and the accompanying drawings.

Referring to fig. 1 to 3, a shaver 100 of the present application includes a cutter head 10, a handle 20, an interconnecting member 40, and a release operation member 30 mounted on the handle 20. The interconnecting member 40 includes a member housing 41, a pivotal support arm 42 extending upward from the left and right sides of the member housing 41, an elastic engaging arm 43 extending upward from the front side of the member housing 41, and an elastic biasing arm 44 extending upward from the rear side of the member housing 41; the interior of the component housing 41 has a receiving cavity 411, the receiving cavity 411 penetrating an upper end face 412 and a lower end face 413 of the component housing 41 to facilitate insertion of the handle 20 from the lower end face 413 into the receiving cavity 411; the free end 431 of the elastic latching arm 43 is bent toward the rear of the component housing 41 and located in the receiving cavity 411, preferably, the free end 431 of the elastic latching arm 43 is a convex arc structure, so that the free end 431 of the elastic latching arm 43 can be more smoothly latched or released with the latching groove 21a described below, but not limited thereto; the free end 441 of the elastic biasing arm 44 is bent toward the front of the member case 41 to form a biasing abutment section 442 located above the free end 431 of the elastic engaging arm 43, and preferably, the biasing abutment section 442 and the free end 441 are each straight, as shown in fig. 5, so as to more effectively avoid interference between the elastic biasing arm 44 and the elastic engaging arm 43, thereby ensuring the reliability of the respective operations. The handle 20 has a plug 21 matching the receiving cavity 411, the plug 21 has a fastening groove 21a, the fastening groove 21a fastens with the free end 431 of the elastic fastening arm 43 when the plug 21 is inserted into the receiving cavity 411, specifically, in the process of inserting the plug 21 into the receiving cavity 411, the plug 21 pushes the free end 431 of the elastic fastening arm 43 to elastically deform along the forward direction of the interconnection member 40 (i.e. the direction indicated by the arrow D in fig. 10b or 10 c), and at the same time, the free end 431 of the elastic fastening arm 43 slides on the plug 21 of the handle 20, so that the free end 431 of the elastic fastening arm 43 is fastened in the fastening groove 21a, and the state is shown in fig. 5, 6 and 10 c. The release operation member 30 is further coupled to the free end 431 of the elastic latching arm 43, so that when the release operation member 30 is operated, the free end 431 of the elastic latching arm 43 is driven to elastically deform, and at this time, the free end 431 of the elastic latching arm 43 elastically deforms in the direction indicated by the arrow D in fig. 10b or fig. 10c, so that the free end 431 of the elastic latching arm 43 is disengaged from the engaging groove 21a of the plug 21 when the lock is released, thereby facilitating the detachment between the interconnection member 40 and the handle 20. The cutter head 10 is mounted at the pivot support arm 42, the pivot support arm 42 provides support for the cutter head 10, and the cutter head 10 pivots back and forth around the pivot support arm 42 to meet the shaving requirement. The elastic biasing arm 44 abuts against the cutter head 10 to provide an elastic biasing force to the cutter head 10 during the forward and backward pivotal movement of the cutter head 10 about the pivotal support arm 42, thereby ensuring the smooth and reliable forward and backward pivotal movement of the cutter head 10 about the pivotal support arm 42. It should be noted that, since the structures of the cutter head 10 and the handle 20 are well known in the art, they are not described in detail herein. More specifically, the following:

as shown in fig. 2 to 6 and 9, the free end 431 of the elastic clamping arm 43 has an upper surface 4311, a lower surface 4312 and an inclined surface 4313 connected between the upper surface 4311 and the lower surface 4312 and located at the rear, the inclined surface 4313 is inclined from the lower to upper direction of the component housing 41 to the front upper side of the component housing 41, on one hand, the plug 21 of the handle 20 smoothly passes over the junction 4314 of the inclined surface 4313 and the lower surface 4312 during the process of being inserted into the receiving cavity 411 and then abuts against the inclined surface 4313; on the other hand, by the inclined surface 4313 abutting against the face surface of the plug 21 (specifically, the rear groove wall surface 212 described below), the inclined surface 4313 increases the blocking force against the plug 21 in the direction of pulling out the plug 21, and thus the accidental release of the engagement between the plug 21 and the free end 431 of the elastic engagement arm 43 is effectively prevented. Specifically, as shown in fig. 6, the intersection 4314 between the inclined surface 4313 and the lower surface 4312 and the intersection 4315 between the inclined surface 4313 and the upper surface 4311 are in arc transition, so that the plug 21 can more smoothly pass over the intersection 4314 between the inclined surface 4313 and the lower surface 4312 and abut against the surface of the inclined surface 4313 when the plug 21 is inserted into the receiving cavity 411, and the intersection 4315 between the inclined surface 4313 and the upper surface 4311 prevents the upper surface 4311 from interfering with the surface-to-surface abutment between the inclined surface 4313 and the plug 21, thereby further ensuring the reliability of the surface-to-surface abutment between the inclined surface 4313 and the plug 21. For example, the upper surface 4311 and the lower surface 4312 are respectively convex arc surfaces, and the arc diameter of the upper surface 4311 is greater than the arc diameter of the lower surface 4312, so that the free end 431 forms the convex arc structure, but not limited thereto. It is understood that, according to practical requirements, the junction 4314 between the inclined surface 4313 and the lower surface 4312 or the junction 4315 between the inclined surface 4313 and the upper surface 4311 is an arc transition, and thus the invention is not limited thereto.

As shown in fig. 2 to 6 and fig. 9, the component housing 41 extends upward to form a left surrounding arm 41a surrounding the receiving cavity 311 from the left side of the component housing 41 and a right surrounding arm 41b surrounding the receiving cavity 411 from the right side of the component housing 41, respectively, and the elastic clamping arm 43 surrounds the receiving cavity 411 from the front side of the component housing 41 and is spaced between the left surrounding arm 41a and the right surrounding arm 41 b; the elastic biasing arm 44 surrounds the receiving cavity 411 from the rear side of the component housing 41 and is spaced apart from and located between the left surrounding arm 41a and the right surrounding arm 41b, so that the plug 21 is surrounded by the left surrounding arm 41a, the elastic latching arm 43, the right surrounding arm 41b and the elastic biasing arm 44 from the circumferential direction, and therefore, the free end 431 of the elastic latching arm 43 can be more stably latched with the latching recess 21a when the plug 21 is inserted into the receiving cavity 411 by using one elastic latching arm 43, thereby further simplifying the structure of the interconnecting component 40. Specifically, the swing support arm 42 on the left side of the member case 41 is located on the left side of the left arm 41a at a distance, and the swing support arm 42 on the right side of the member case 41 is located on the right side of the right arm 41b at a distance, so that the cutter head 10 mounted on the swing support arm 42 is prevented from interfering with the left arm 41a and the right arm 41b during the swing, respectively, thereby ensuring the reliability of the swing of the cutter head 10, but not limited thereto.

As shown in fig. 3, 5, 10a, 10b and 10c, the lock releasing operation member 30 includes a pressing head 31 slidably disposed on the handle 20 and a pushing rod 32 connected to the pressing head 31, the pushing rod 32 is inserted into the plug 21, the pushing rod 32 further extends to the engaging recess 21a and is located under the free end 431 of the elastic engaging arm 43, so that when a user presses the pressing head 31, the pushing rod 32 slides along the pressing head 31 relative to the handle 20, so that the sliding pushing rod 32 pushes the free end 431 of the elastic engaging arm 43 to elastically deform to disengage from the engaging recess 21a of the plug 21, thereby releasing the free end 431 of the elastic engaging arm 43 from the engaging recess 21a of the plug 21. Specifically, the pressing head 31 and the pushing rod 32 are slidably disposed along the vertical direction of the handle 20, so that when the pressing head 31 is slid along the direction indicated by the arrow beside the pressing head 31 in fig. 10b or 10c, the pushing rod 32 is slid along with the pressing head 31, so that the free end 431 of the elastic engaging arm 43 is pushed by the slid pushing rod 32 to be elastically deformed along the direction indicated by the arrow D in fig. 10b or 10c, and the free end 431 of the elastic engaging arm 43 is disengaged from the engaging groove 21a of the plug 21, thereby allowing the interconnecting member 40 to be detached from the handle 20, but not limited thereto.

As shown in fig. 7 and 8, the notch 211 of the engaging recess 21a is formed on the front surface 21b and the upper surface 21c of the plug 21, and the rear groove wall surface 212 of the engaging recess 21a is inclined from the bottom-to-top direction of the handle 20 to the front-to-top direction of the handle 20, so that the rear groove wall surface 212 matches the inclination of the inclined surface 4313, and the rear groove wall surface 212 of the engaging recess 21a abuts against the inclined surface 4313; when the rear groove wall surface 212 of the fitting recess 21a abuts against the inclined surface 4313, the intersection 4314 between the inclined surface 4313 and the lower surface 4312 is located in the space 2111 between the rear groove wall surface 212 and the lower groove wall surface 213 of the fitting recess 21a, as shown in fig. 6. Specifically, after the engaging groove 21a, the groove wall surface 212 and the lower groove wall surface 213 are both flat and the included angle therebetween is an acute angle, and the left groove wall surface 214 and the right groove wall surface 215 of the engaging groove 21a are obliquely arranged from the bottom to the top of the handle 20 in the direction gradually approaching each other, so that the free end 431 of the elastic engaging arm 43 is more smoothly engaged with the engaging groove 21a in the process of inserting the plug 21 into the receiving cavity 411, and the free end 431 of the elastic engaging arm 43 located in the engaging groove 21a is effectively prevented from swinging left and right by the left groove wall surface 214 and the right groove wall surface 215. In order to make the plug 21 more easily and smoothly pass over the junction 4314 between the inclined surface 4313 and the lower surface 4312, the rear wall of the latching recess 21a is inclined forward and upward to form a protruding tongue 21d with the same thickness dimension, and the protruding tongue 21d is clamped between the free ends 431 and 441 of the elastic latching arm 43 and the elastic biasing arm 44, as shown in fig. 6; of course, the thickness of the protruding tongue 21d may be gradually increased or decreased during the forward and upward inclined extension according to actual requirements, and is not limited thereto.

With reference to fig. 10a to 10c, the process of fastening the handle 20 and the interconnecting member 10 will be described: as shown in fig. 10a, the handle 20 is inserted into the receiving cavity 411 of the interconnecting member 10 in the direction of the arrow beside the plug 21 until the end of the protruding tongue 21d of the plug 21 abuts the intersection 4314 between the inclined surface 4313 and the lower surface 4312; when the end of the protruding tongue 21D of the plug 21 abuts against the intersection 4314 between the inclined surface 4313 and the lower surface 4312, the plug 21 is further inserted into the receiving cavity 411 by keeping the original direction, so that the end of the protruding tongue 21D of the plug 21 pushes the free end 431 of the elastic locking arm 43 to elastically deform in the direction indicated by the arrow D in fig. 10b, as shown in fig. 10b, so that the intersection 4314 between the inclined surface 4313 and the lower surface 4312 avoids the end of the protruding tongue 21D of the plug 21 to allow the end of the protruding tongue 21D of the plug 21 to pass over the intersection 4314 between the inclined surface 4313 and the lower surface 4312, and the intersection 4314 between the inclined surface 4313 and the lower surface 4312 enters the locking groove 21a from the notch 211 of the locking groove 21a, and under the elastic force of the elastic locking arm 43, so that the intersection 4314 between the inclined surface 4313 and the lower surface 4312 slides along the groove wall 43212 a of the locking groove 21a until the free end 4314 slides along the groove wall 4313, as shown in fig. 13 c.

Compared with the prior art, because the interconnecting member 40 of the present application further includes the elastic clamping arm 43 extending upward from the front side of the member housing 41 and the elastic biasing arm 44 extending upward from the rear side of the member housing 41, the free end 431 of the elastic clamping arm 43 is bent toward the rear of the member housing 41 and is located in the receiving cavity 411, and the free end 441 of the elastic biasing arm 44 is bent toward the front of the member housing 41 to form the biasing abutting section 442 located above the free end 431 of the elastic clamping arm 43, the interconnecting member 40 of the present application directly replaces the existing combined structure composed of the biasing tongue and the spring with the elastic biasing arm 44; meanwhile, with the aid of the elastic clamping arm 43, in the process of inserting the plug 21 of the handle 20 into the receiving cavity 411, the free end 431 of the elastic clamping arm 43 is pushed by the plug 21 of the handle 20 to generate elastic deformation along the direction away from the elastic biasing arm 44, and simultaneously, the free end 431 of the elastic clamping arm 43 slides on the plug 21 of the handle 20 until the free end 431 of the elastic clamping arm 43 is buckled with the buckling groove 21a of the plug 21, that is, the single-point buckling between the interconnecting member 40 and the handle 20 can be realized by one elastic clamping arm 43, so that the structure is simplified; therefore, the interconnecting member 40 of the present application can simplify the structure and the installation process, and can realize the single point engagement between the handle 20 and the interconnecting member 40 while ensuring the reliable engagement between the handle 20 and the interconnecting member 40. Similarly, the shaver 100 of the present application can simplify the structure and the mounting process, and can realize the single-point engagement between the handle 20 and the interconnecting member 40 under the condition that the engagement between the handle 20 and the interconnecting member 40 is ensured to be reliable.

It is noted that the front, rear, left and rear sides of the member housing 41 are established such that when the shaver 100 is shaving beard downward, the side of the interconnecting member 40 facing the skin is referred to as the front, and the side of the interconnecting member 40 facing away from the skin is referred to as the rear, while the left side on the left side is referred to as the left side of the interconnecting member 40, the right side on the right side is referred to as the right side of the interconnecting member 40, the upper end on the upper side is referred to as the interconnecting member 40, and the lower end on the lower side is referred to as the interconnecting member 40.

The above disclosure is only a preferred embodiment of the present application, and certainly should not be taken as limiting the scope of the present application, which is therefore intended to cover all modifications and equivalents of the claims.
