Although the above-mentioned floating cutter head structure can make the cutter head float vertically and swing universally, the vertical floating and universal swing of the cutter head must rely on the mutual cooperation of the four components of the shell, the connecting piece, the pressure plate, and the elastic reset piece. The number of components is large, the assembly is complicated, and the cost is relatively high. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the utility model provides a razor head floating connection structure and a razor.

[0005] The utility model is realized by the following technical solutions:

[0006] The floating connection structure of the shaving head comprises:

[0007] A connecting base, the connecting base is used to connect with the fuselage, and the connecting base is provided with a first connecting portion;

[0008] A mounting base, the mounting base is used to connect with the cutter head, the mounting base is provided with a second connecting portion, the second connecting portion and the first connecting portion can be movably matched so that the mounting base can move vertically and swing 360 degrees, the second connecting portion has a first position moving upward to abut against the first connecting portion and a second position moving downward to abut against the first connecting portion, the mounting base moves vertically to switch the second connecting portion between the first position and the second position, the mounting base is provided with a third connecting portion, and the third connecting portion is integrally arranged with the mounting base;

[0009] A first elastic member, wherein the upper end of the first elastic member is connected to the third connecting portion, the lower end of the first elastic member is connected to the first connecting portion, and the first elastic member is used to provide a driving force to the mounting base so that the second connecting portion is restricted to the first station.

[0010] The utility model discloses a floating connection structure for a razor head, comprising a connection base, a mounting base and a first elastic member. During shaving, the driving force of the first elastic member can be overcome by pushing the cutter head to move on the face, so that the cutter head can float vertically and swing 360 degrees, thereby making the cutter head change with the change of the facial curve, ensuring that the cutter head always fits the facial skin and improving the shaving effect. Among them, since the third connection part and the mounting base are integrally arranged, only three components, namely the connection base, the mounting base and the first elastic member, need to be configured to realize the vertical floating and 360-degree swing of the cutter head. Compared with the prior art, one component is reduced, the structure is simplified, and assembly is easier. While improving assembly efficiency, it can also reduce costs, which is more conducive to the promotion and application of the floating connection structure for razor heads.

[0011] In one embodiment, the second connecting portion has a guide hole and a limiting groove, and the limiting groove is provided on the side wall of the guide hole;

[0012] The first connecting part is provided with a guiding part and a limiting part, and the guiding part and the limiting part are arranged in sequence around the vertical center line of the connecting base. The guiding part and the guiding hole can be movably matched to play a guiding role, so that the vertical movement and 360-degree swing of the mounting base are smoother. The limiting part can be movably inserted in the limiting groove to limit the second connecting part between the first station and the second station to prevent the second connecting part from being separated from the first connecting part, so that the mounting base and the connecting base are reliably connected together.

[0013] In one embodiment, the guide portion and the limit portion are spaced apart around the vertical center line of the connection base, and both the guide portion and the limit portion can swing toward or away from the vertical center line of the connection base, so that the first connection portion can be telescopically moved laterally;

[0014] The first connection part has a condensed state in which the maximum outer diameter is reduced to a value smaller than the diameter of the guide hole, so that the first connection part can vertically enter and exit the guide hole. The first connection part also has an extended state in which the maximum outer diameter is expanded to a value larger than the diameter of the guide hole. The first connection part moves laterally to switch between the condensed state and the extended state. In this way, during assembly, the first connection part can be pushed to move toward the vertical center line of the first connection base by pinching the first connection part with fingers, driving the first connection part to switch from the extended state to the condensed state, and then the first connection part in the condensed state is pushed from bottom to top into the guide hole, pushing the first connection part in the guide hole to disengage from the fingers, so that the first connection part is released, so that the guide part and the limit part are reset to a position away from the vertical center line of the connection base under the elastic force of their own materials, driving the connection base to reset from the condensed state to the extended state, so that the guide part and the guide hole can move. The matching, limiting part and limiting groove can be movably matched to realize the reliable connection between the connecting base and the mounting base. The installation is convenient and the installation efficiency can be improved. When disassembling, the first connecting part can be pinched with fingers to push the guiding part and the limiting part to move toward the vertical center line direction close to the first connecting base, driving the first connecting part to switch from the extended state to the contracted state, and then the first connecting part in the contracted state is pulled out of the guide hole. The disassembly is convenient and the disassembly efficiency is high, which facilitates the replacement of the connecting base, so that the vertical movement stroke and swing angle of the mounting base can be changed according to the user's usage requirements.

[0016] The limiting part is provided with a second installation guide inclined surface, and the second installation guide inclined surface can be slidably matched with the first installation guide inclined surface to guide the limiting part to match with the limiting groove. In this way, during the installation process, by making the second installation guide inclined surface slidably matched with the first installation guide inclined surface, the limiting part can be pushed to move toward the vertical center line of the connection base, so that the connection base automatically switches from the extended state to the contracted state, replacing the manual kneading of the first connection part, making the installation operation more convenient, improving the installation efficiency, and making the installation smoother.

[0017] In one embodiment, there are multiple limiting grooves, and the multiple limiting grooves are arranged at intervals around the vertical center line of the second connecting portion;

[0018] The number of both the guide parts and the limiting parts is multiple, the guide parts and the limiting parts are arranged alternately, and each limiting part is matched with the corresponding limiting groove. By the multiple guide parts being movably matched with the guide holes at the same time, the vertical movement smoothness of the installation base can be improved. At the same time, by the multiple limiting parts being movably matched with the corresponding limiting grooves, the installation base and the connection base can be reliably restricted from being disconnected, thereby improving the connection reliability between the installation base and the connection base, and the structural reliability is higher.

[0019] In one embodiment, the third connecting portion is provided with a transverse annular portion and a vertical annular portion, the outer ring of the transverse annular portion is connected to the mounting base, the transverse annular portion is arranged around the swing center line of the mounting base, and the upper end of the vertical annular portion is connected to the inner ring of the transverse annular portion;

[0020] The upper end of the first elastic member abuts against the bottom of the transverse annular portion, and the upper end of the first elastic member is sleeved on the vertical annular portion, so that the first elastic member and the third connecting portion are reliably connected together, preventing the first elastic member from detaching from the third connecting portion at will, thereby ensuring that the mounting base can be reset.

[0021] In one embodiment, an annular positioning portion is provided in the first connecting portion, and the annular positioning portion is arranged around the vertical center line of the connecting base. The lower end of the first elastic member is sleeved on the annular positioning portion to ensure that the first elastic member and the first connecting portion are reliably connected together, thereby preventing the first elastic member from detaching from the first connecting portion at will, thereby ensuring that the mounting base can be reset.

[0022] In one embodiment, the razor head floating connection structure further comprises:

[0023] The second elastic member is arranged outside the mounting base, the upper end of the second elastic member is connected to the mounting base, the lower end of the second elastic member is connected to the connecting base, and the second elastic member is arranged around the swing center line of the mounting base, and the second elastic member is used to provide a driving force to the mounting base so that the second connecting part is maintained at the first station. Since the second elastic member is provided, the second elastic member can provide a driving force to the mounting base to ensure that the second connecting part is reliably maintained at the first station. At the same time, the second elastic member can be used to provide floating support for the mounting base, which can improve the stability and smoothness of the mounting base when it floats vertically and swings.

[0024] In one embodiment, the mounting base has a first positioning groove and a plurality of clamping grooves, the first positioning groove is arranged around the swing center line of the mounting base, the clamping groove is located on the side wall of the first positioning groove, and the plurality of clamping grooves are arranged at intervals along the first positioning groove;

[0025] The outer wall of the connection base has a second positioning groove, and the second positioning groove is arranged around the vertical center line of the connection base;

[0026] The upper end of the second elastic member cooperates with the first positioning groove, and the lower end of the second elastic member cooperates with the second positioning groove;

[0028] A locking ring, at least a portion of which is disposed in the first positioning groove, and the locking ring is provided with a plurality of snap protrusions, each of which cooperates with the corresponding snap groove to connect the locking ring to the mounting base, and the locking ring and the upper end bottom wall of the second elastic component abut against each other to limit the upper end of the second elastic component within the first positioning groove. In this way, the second elastic member can be installed and positioned by making the upper end of the second elastic member cooperate with the first positioning groove and the lower end of the second elastic member cooperate with the second positioning groove, which is convenient for quick installation of the second elastic member and can improve installation efficiency. At the same time, since the mounting base is movable relative to the connecting base, the second elastic member and the mounting base can be reliably connected together by providing a locking ring, thereby preventing the second elastic member from detaching from the mounting base when the mounting base moves, and the structural reliability is higher. In addition, since the locking ring and the mounting base are connected by means of the cooperation of the snap protrusion and the snap groove, the locking ring can be installed without tools, which is convenient for quick installation of the locking ring on the mounting base and improves installation efficiency.
