The utility model provides a cutter head structure of a hair trimmer, and aims to solve the technical problem that the working noise of the hair trimmer is large.
In the embodiment of the present utility model, referring to fig. 1 to 4, fig. 1 shows a schematic structural diagram of an embodiment of the hair trimmer of the present utility model; FIG. 2 is a schematic view of an embodiment of a head structure of a hair trimmer of the present utility model; FIG. 3 is an exploded view of one embodiment of a cutter head structure of the hair trimmer of the present utility model; fig. 4 is a schematic cross-sectional view of an embodiment of a head structure of a hair trimmer according to the present utility model.
The head structure of the hair trimmer comprises a base 20, a cutting unit 30 and a plastic limiting piece 40; the cutting unit 30 comprises a bracket 31 and a blade module 32, the blade module 32 is mounted on the bracket 31, the bracket 31 can be elastically and floatingly mounted on the base 20 along the up-down direction, the bracket 31 is provided with a limit lug 311, and the limit lug 311 is provided with an upward first limit surface 312; the plastic limiting part 40 is mounted on the base 20, the plastic limiting part 40 is provided with a downward second limiting surface 41, the limiting lug 311 is located between the base 20 and the second limiting surface 41, and the second limiting surface 41 is in limiting abutment with the first limiting surface 312 so as to limit the upward movement of the bracket 31 relative to the base 20.
In this embodiment, the hair trimmer has a housing 10, the housing 10 being provided with a mounting opening and a receiving space communicating with the mounting opening. The blade module 32 extends out of the mounting opening. The housing 10 is a metal shell, and if the limiting lug 311 abuts against the housing 10 to limit the upward movement of the bracket 31, the limiting lug 311 generates a loud noise each time it abuts against the housing 10.
The base 20 is fixed in the shell 10 and is opposite to the mounting opening, the base 20 can support the bracket 31 and the plastic limiting piece 40, and the bracket 31 can float up and down relative to the mounting opening by taking the base 20 as a support, so that when a user contacts the cutting unit 30 with a skin part, the bracket 31 can be close to the base 20 under the action of pressure, thereby realizing the buffering effect, reducing the instant impact force on the user, and preventing the blade module 32 from directly contacting the skin of the user to cut the user, thereby improving the shaving experience of the user.
The limiting lugs 311 can float up and down along with the bracket 31, and the plastic limiting piece 40 is fixed relative to the base 20. In the unused state, the first limiting surface 312 of the limiting lug 311 is kept in contact with the second limiting surface 41 of the plastic limiting member 40, so as to prevent the bracket 31 from being separated from the mounting opening upwards.
During use of the hair trimmer, the blade module 32 moves together with the bracket 31 towards the base 20 under pressure, and when the external force is removed, the bracket 31 automatically resets upwards and finally stops under the stop action of the plastic stopper 40. The surface of the plastic part is softer than the metal part, and the noise generated when the plastic part is impacted by the limiting lugs 311 each time is smaller, so that the working noise of the hair trimmer can be effectively reduced, and the user experience is improved.
The plastic limiting piece 40 may be strip-shaped, frame-shaped, or have other irregular shapes, which is not limited herein, and only needs to satisfy that the plastic limiting piece 40 has the downward second limiting surface 41.
Specifically, as shown in fig. 3, the plastic limiting member 40 includes a limiting portion 42 and a supporting portion 43, the limiting portion 42 is disposed around the bracket 31, the top of the supporting portion 43 is connected to the limiting portion 42, the bottom of the supporting portion is supported by the base 20, and the second limiting surface 41 is disposed on a side of the limiting portion 42 facing the base 20.
The limiting portion 42 is arranged on the bracket 31 in a frame-shaped ring, the supporting portion 43 supports the limiting portion 42, so that a movable interval is formed between the limiting portion 42 and the base 20, and the limiting lug 311 is located in the movable interval. The limiting part 42 is arranged around the bracket 31, so that the limiting part 42 can protect the bracket 31, and the obstruction of other structures to the floating process of the bracket 31 is reduced, thereby improving the working stability of the cutting unit 30. The number of the supporting portions 43 may be plural, and the supporting portions 43 are disposed along the circumferential direction of the limiting portion 42 at intervals, so as to increase the supporting positions of the limiting portion 42, thereby improving the mounting stability of the plastic limiting member 40 on the base 20.
The support portion 43 may be simply abutted against the base 20, or may be fixedly connected to the base 20. In practical applications, as shown in fig. 2 and 3, the base 20 is provided with a via hole 21, the supporting portion 43 is provided with a fixing hole 431, and the via hole 21 is connected with the fixing hole 431 through a fastener. The fixing hole 431 may be a screw hole, and the fastening member may be a screw, and the fastening member is in threaded engagement with the fixing hole 431 to fixedly connect the supporting portion 43 and the base 20 in series, thereby further improving the installation stability of the plastic limiting member 40 on the base 20.
The number of the limit lugs 311 may be one or two or more. As shown in fig. 3 and 4, the number of the limit lugs 311 is at least two, and at least two limit lugs 311 are spaced apart along the length direction of the bracket 31; and/or the number of the limit lugs 311 is at least two, and the limit lugs 311 are arranged on two sides of the bracket 31 in the width direction. The number of the limiting lugs 311 can be 4, and every two limiting lugs 311 are arranged at intervals along a long side edge of the bracket 31, so that the limiting abutting position of the plastic limiting piece 40 to the bracket 31 can be increased, and the limiting effect is improved.
Specifically, as shown in fig. 3, the width and/or length of the plastic limiting member 40 decreases from a side close to the base 20 toward a side far away from the base 20, so that the plastic limiting member 40 is integrally formed in a shape with a wide bottom and a narrow top, so that the mounting stability of the plastic limiting member 40 is ensured, and meanwhile, the occupied space of the plastic limiting member 40 in the housing 10 is reduced, so that the cutter head structure of the hair trimmer is more compact.
The limiting portion 42 and the supporting portion 43 may be formed by separate processes and then connected together, or may be formed integrally. In practical application, the limiting portion 42 and the supporting portion 43 are integrally formed by injection molding, so that the plastic part is easier to be formed by injection molding, and the production efficiency of the plastic limiting portion 40 can be improved.
The floating installation mode of the bracket 31 may be realized by a magnetic suspension structure or an elastic structure, and is not limited herein.
As shown in fig. 3 and 5, fig. 5 is an exploded view of another embodiment of the cutter head structure of the hair trimmer of the present utility model. The head structure of the hair trimmer further comprises an elastic member 50, and the bracket 31 is elastically floatably mounted to the base 20 via the elastic member 50. The elastic member 50 may be a spring, or may be a member that is elastically deformed and restored, such as sponge, rubber, or silicone. The elastic member 50 has one end connected to or abutting against the base 20 and the other end connected to or abutting against the bracket 31. When the bracket 31 receives pressure from the base 20, the elastic member 50 is compressed and generates elastic potential energy; when the pressure applied to the bracket 31 is removed, the elastic potential energy of the elastic member 50 is converted into kinetic energy and pushes the bracket 31 to return in a direction away from the base 20.
Specifically, as shown in fig. 3 and 5, the cutter head structure of the hair trimmer further includes a guide post 51, the guide post 51 is connected to the base 20, the support 31 is provided with a guide hole 313, the guide post 51 is slidably matched with the guide hole 313, and the elastic member 50 is sleeved on the base 20 and abuts against the guide post 51. The elastic member 50 is sleeved on the guide post 51, so as to prevent the elastic member 50 from bending and deforming during the compression process, thereby improving the structural stability of the elastic member 50.
Illustratively, as shown in fig. 5, the blade module 32 includes a mounting frame 321 and a razor 322 mounted to the mounting frame 321, and the mounting frame 321 is elastically floatably mounted to the holder 31 in the up-down direction. The floating installation manner of the installation frame 321 may be the same as the bracket 31 or may be different from the bracket 31, and is not limited herein.
When the blade structure contacts the skin of the user, the razor 322 first directly receives force from the user and then transfers the force to the mounting frame 321 through the floating mounting structure. The floating mounting structure can cushion the razor 322 when the razor 322 is pressed toward the base 20, so as to reduce the instantaneous impact force of the razor 322 and prevent the razor 322 from being damaged due to excessive instantaneous stress.
In the technical scheme of the hair trimmer, the second limiting surface 41 of the plastic limiting piece 40 and the first limiting surface 312 of the limiting lug 311 are mutually abutted to limit the bracket 31, so that the maximum distance between the cutting unit 30 and the base 20 can be limited, and the cutting unit 30 is prevented from being separated from the base 20 or the shell 10 arranged in an electric shearing way, so that the installation stability of the cutting unit 30 is ensured; the plastic material is less in sound generated when being impacted, so that the noise generated when the cutting unit 30 is floated and reset each time can be effectively reduced, and the user experience is improved.
