In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] Refer to the following Figure 1 and Figure 2 An electric shaver with a storable blade head according to some embodiments of the present application is described.

[0032] See also Figure 1 and Figure 2 As shown, an embodiment of the present application provides an electric shaver with a retractable cutter head, comprising: a housing 1, a supporting member 2, a transmission mechanism, a driving device 4 and a cutter head assembly 5 arranged in the housing 1;

[0033] Wherein, the cutter head assembly 5 is rotatably arranged on the supporting member 2;

[0034] The driving device 4 is connected to the supporting member 2 through a transmission mechanism, and can drive the supporting member 2 to rise and fall along the height direction of the shell 1 to force the cutter head assembly 5 to flip relative to the supporting member 2 and be stored in the shell 1 or extend from the shell 1.

[0035] The electric shaver with storable blades provided in the present application can utilize the driving device 4 to drive the blade head assembly 5 to move downward through the transmission mechanism after use, and the blade head assembly 5 will be subjected to the lateral thrust of the shell 1 while moving downward, so that the blade head assembly 5 is flipped toward the inside of the shell 1 relative to the supporting member 2 and stored in the shell 1, thereby reducing the space occupied and facilitating carrying outside. In addition, the blade head assembly 5 is stored in the shell 1 and will not collide with other objects and be damaged, which is safer and more reliable, and also helps to extend the service life of the shaver.

[0036] When it is needed, the driving device 4 can be used to drive the cutter head assembly 5 to move upward through the transmission mechanism, so that the cutter head assembly 5 gradually extends out from the housing 1.

[0037] The above operation is simple, convenient and highly practical.

[0038] It can be seen that the blade head assembly 5 of the electric shaver with storable blade heads provided in the present application can be stored in the housing 1 when not in use, does not occupy extra space, is more convenient to carry, and is protected by the housing 1 and is not easily damaged.

[0039] Of course, the cutter head assembly 5 is not limited to being rotatably arranged on the support member 2. The cutter head assembly can also be fixedly arranged on the support member. When the driving device drives the support member to move upward or downward along the height direction of the shell through the transmission mechanism, the cutter head assembly also extends upward from the shell along the height direction of the shell, or is stored downward into the shell. Of course, the assembly relationship between the cutter head assembly and the support member can also take other forms.

[0040] In this embodiment, preferably, Figure 1 and Figure 2 As shown, the transmission mechanism includes a screw rod 3, a screw nut and a nut seat; wherein one end of the screw rod 3 is connected to the driving device 4, and the other end of the screw rod 3 extends toward the cutter head assembly 5;

[0041] The nut is rotatably sleeved on the screw rod 3, the nut seat is connected to the screw rod 3, and the supporting member 2 is connected to the nut seat.

[0042] According to the structure described above, the driving device 4 drives the lead screw to rotate, and the lead screw drives the nut to drive the nut seat to move along the height direction of the lead screw, thereby driving the support member 2 connected to the nut seat to move along the height direction of the outer shell 1, laying the foundation for realizing the rotation of the cutter head assembly 5 relative to the support member 2 and being stored in the outer shell 1 or extending from the outer shell 1.

[0043] Due to the use of a screw drive mechanism, the structure is simpler, which is convenient for purchase and subsequent replacement and maintenance, and has a long service life and is not prone to jamming.

[0044] Of course, the transmission mechanism is not limited to the above-mentioned screw transmission mechanism, and some suitable transmission mechanisms can also be selected according to actual needs.

[0045] A guide member 8, such as a guide round rod, is disposed on both sides of the screw rod 3, one end of the guide member 8 is connected to the housing 1, and the other opposite end of the guide member 8 is connected to the limit portion 22. The guide rod guides the screw rod 3 to prevent the screw rod 3 from tilting.

[0046] In this embodiment, preferably, Figure 1 and Figure 2 As shown, the support member 2 includes a main body 21 and a limiting portion 22; wherein, the limiting portion 22 is connected to one end of the main body 21 away from the cutter head assembly 5, and the limiting portion 22 and the main body 21 enclose a movement space 9. It can be seen that a concave cavity is formed at one end of the main body 21 away from the cutter head assembly 5, and the limiting assembly closes the concave cavity, thereby forming the above-mentioned movement space 9; the cutter head assembly 5 is rotatably connected to the main body 21; and the nut seat is connected to the limiting portion 22.

[0047] Specifically, the main body 21 includes a supporting seat 211 and a moving seat 212 connected to each other; wherein the cutter head assembly 5 is rotatably connected to one end of the supporting seat 211 away from the moving seat 212; the limiting portion 22 is connected to one end of the moving seat 212 away from the supporting seat 211, and the limiting portion 22 and the moving seat 212 enclose a movement space 9. It can be seen that the shapes and sizes of the supporting seat 211 and the moving seat 212 can be set according to actual needs, and then the two are assembled together.

[0048] Optionally, the limiting portion 22 may be a plate-shaped structure.

[0049] like Figure 1 and Figure 2 As shown, the electric shaver with storable blade heads further comprises a first limiting member 6 disposed in the movement space 9 and a second limiting member 7 disposed outside the movement space 9, the screw rod 3 is rotatably connected to the first limiting member 6 and the second limiting member 7 in sequence, and along the height direction of the housing 1, the first limiting member 6, the limiting portion 22 of the support member 2 and the second limiting member 7 are sequentially disposed;

[0050] Part of the structure of the first limiting member 6 passes through the opening formed by the main body 21 of the supporting member 2 and is connected to the housing 1 .

[0051] According to the structure described above, the first limiting member 6 and the second limiting member 7 limit the limiting portion 22 of the supporting member 2 within the space formed by the two, thereby limiting the movement range of the supporting member 2, so that the cutter head assembly 5 rotatably connected to the supporting member 2 can be just accommodated in the outer shell 1 and extended out of the outer shell 1.

[0052] Of course, a controller may also be provided in the housing 1 to control the working time of the driving device 4, so as to cooperate with the limiting function of the supporting member 2, which is safer and more reliable.

[0053] In addition, in addition to achieving the above functions, the first limiting member 6 can also support the screw rod 3 to prevent the screw rod 3 from tilting, thereby affecting the storage of the cutter head assembly 5 or extending from the housing 1.

[0054] In this embodiment, preferably, the opening extends along the moving direction of the supporting member 2 (not shown in the figures).

[0055] According to the structure described above, the purpose of providing the above-mentioned opening is to ensure that the support member 2 does not interfere with the first limiting member 6 during the movement when it has not reached the specified position, that is, the limit position.

[0056] In this embodiment, preferably, the cutter head assembly 5 is rotatably connected to the support member 2 via a connecting shaft provided on the support member 2 (not shown in the figure).

[0057] Specifically, the connecting shaft may be formed with a first mounting hinge, and the connecting shaft is fixedly connected to the first mounting hinge, and the first mounting hinge is connected to the support member 2 by a fastener, so as to realize the installation of the connecting shaft on the support member 2, and the connecting shaft may be formed with a second mounting hinge, and the second mounting hinge is rotatably connected to the connecting shaft, and the second mounting hinge is fixedly connected to the cutter head assembly 5, for example, by fasteners or welding.

[0058] Further, preferably, the electric shaver with storable blades also includes an elastic reset member, which is arranged between the blade assembly 5 and the connecting shaft and is used to provide a partial driving force for driving the blade assembly 5 to extend outward from the housing 1 (not shown in the figure).

[0059] According to the structure described above, as the cutter head assembly 5 is received into the housing 1, the elastic return member is compressed, and when the cutter head assembly 5 gradually extends out of the housing 1, the elastic return member releases and restores the deformation, so that the cutter head assembly 5 can be quickly and fully extended, that is, quickly restored to the original usage state.

[0060] Among them, optionally, the elastic reset component is a torsion spring, which is sleeved on the connecting shaft, and one end of the torsion spring is connected to the connecting shaft, and the other opposite end of the torsion spring is connected to the cutter head assembly 5. The torsion spring is a commonly used spring component on the market, which is easy to purchase and low in cost.

[0061] In this embodiment, preferably, Figure 1 and Figure 2 As shown, there are three cutter head assemblies 5 , and the three cutter head assemblies 5 are evenly arranged along the center line of the housing 1 .

[0062] According to the structure described above, the three cutter head assemblies 5 are conventional structural settings currently available on the market, which meet the design requirements of ergonomics. The specific structure has been disclosed in the prior art and will not be described in detail here.

[0063] Of course, the number of the cutter head assemblies 5 is not limited to three, and can be set according to actual needs.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
