[0029] As Figure 1 shown, the electric shaver with a charging structure provided by the embodiment of the present application includes: a main body 1 and a charging base 2. Both the main body 1 and the charging base 2 are provided with charging contacts, and when the main body 1 is placed on the charging base 2, it is charged through the charging contacts.

[0030] In some embodiments, both the main body 1 and the charging base 2 have a positive contact and a negative contact. For the convenience of description, the positive contact and the negative contact of the main body 1 are respectively defined as a positive contact A11 and a negative contact A12, and the positive contact and the negative contact of the charging base 2 are respectively defined as a positive contact B21 and a negative contact B22, as Figure 1 shown. When the main body 1 is placed on the charging base 2, the positive contact A11 and the negative contact B22 are conducted, the negative contact A12 and the positive contact B21 are conducted, the positive contact B21 transmits the current from the charging base 2 to the negative contact A12, and the current returns to the negative contact B22 after flowing through the battery of the main body 1 via the positive contact A11, thereby realizing the charging of the main body 1.

[0031] In some embodiments, the charging contacts of the main body 1 and / or the charging contacts of the charging base 2 adopt spring pins. As Figure 1 shown, this embodiment shows that the charging contacts (positive contact A11 and negative contact A12) on the main body 1 adopt spring pins. Since the spring pins have the characteristic of being retractable, it can ensure the effective contact between the charging contacts on the main body 1 and the charging contacts on the charging base 2 during charging. However, the embodiments of the present application do not make any limitation on this.

[0032] In some embodiments, as Figure 1 shown, a sealing ring 13 can be provided between the main body 1 and its charging contacts. Such a setting can achieve the waterproof function of the main body 1. However, the embodiments of the present application do not make any limitation on this.

[0033] In some embodiments, one of the positive contact and the negative contact on the charging base 2 is annular and arranged around the other. That is to say, one of the positive contact B21 and the negative contact B22 is annular and arranged around the other. As Figure 1As shown, in this embodiment, the positive electrode contact B21 is shown as being annular and arranged around the negative electrode contact B22. With such an arrangement, the main body 1 can achieve conduction of the charging contacts when rotating to different positions relative to the charging base 2, so that the main body 1 and the charging base 2 are not limited to a unique position for connection. This can make the connection and disconnection between the main body 1 and the charging base 2 more flexible and convenient, thereby improving the technical problem in the prior art that it is relatively inconvenient to connect and disconnect the razor main body 1 and the charging base 2, resulting in a poor user experience. However, the embodiments of this application do not make any limitations in this regard. In other embodiments, the negative electrode contact B22 can be arranged in an annular shape and surround the positive electrode contact B21.

[0034] For example, in the case where the positive electrode contact A11 and the negative electrode contact B22 are conducting and the negative electrode contact A12 and the positive electrode contact B21 are conducting, since the positive electrode contact B21 is annular and arranged around the negative electrode contact B22, when the main body 1 rotates around the axis direction of the positive electrode contact A11, it will not cause disconnection between the corresponding contacts.

[0035] In some embodiments, as Figure 3 shown, the charging base 2 includes a housing 23, and the housing 23 includes a first housing 23a and a second housing 23b. The first housing 23a and the second housing 23b can be connected by means such as screws 24 and snaps. During specific assembly, the first housing 23a and the second housing 23b can be separated first, and then the positive electrode contact B21, the negative electrode contact B22, and other components (such as a circuit board, etc.) are installed on the first housing 23a, and finally the first housing 23a and the second housing 23b are connected and fixed. However, the embodiments of this application do not make any limitations in this regard.

[0036] In some embodiments, both the positive electrode contact B21 and the negative electrode contact B22 are provided with connection terminals. For the convenience of description, the connection terminal of the positive electrode contact B21 is defined as the first connection terminal 21a, and the connection terminal of the negative electrode contact B22 is defined as the second connection terminal 22a, as Figure 3 shown. During specific setting, the first connection terminal 21a and the second connection terminal 22a can be used to fix the charging contact where they are located to the housing 23, or can be used to electrically connect the charging contact where they are located to the circuit board. It should be understood that the positive electrode contact B21 and the negative electrode contact B22 can be directly fixed to the housing 23, or the positive electrode contact B21 and the negative electrode contact B22 can be indirectly fixed to the housing 23. For example, the positive electrode contact B21 and the negative electrode contact B22 are indirectly fixed to the housing 23 through a circuit board. However, the embodiments of this application do not make any limitations in this regard.

[0037] In some embodiments, the number of the first connection terminals 21a is multiple, and the multiple first connection terminals 21a are distributed at intervals along the circumferential direction of the positive electrode contact B21. AsFigure 3 As shown, in this embodiment, the number of the first connection terminals 21a is three, and the three first connection terminals 21a are circumferentially spaced along the circumference of the positive electrode contact B21. Such an arrangement can improve the fixing effect of the positive electrode contact B21 and can also improve the reliability of the connection between the positive electrode contact B21 and the circuit board. However, the embodiments of the present application do not make any limitations in this regard.

[0038] In some embodiments, the number of the second connection terminals 22a is multiple, and the multiple second connection terminals 22a are circumferentially spaced along the circumference of the negative electrode contact B22. As Figure 3 shown, in this embodiment, the number of the second connection terminals 22a is three, and the three second connection terminals 22a are circumferentially spaced along the circumference of the negative electrode contact B22. Such an arrangement can improve the fixing effect of the negative electrode contact B22 and can also improve the reliability of the connection between the negative electrode contact B22 and the circuit board. However, the embodiments of the present application do not make any limitations in this regard.

[0039] In some embodiments, the outer surfaces of the positive electrode contact B21 and the negative electrode contact B22 are flush. As Figure 1 shown, in this embodiment, the outer surfaces of the positive electrode contact B21 and the negative electrode contact B22 are the upper surfaces of the positive electrode contact B21 and the negative electrode contact B22. Such an arrangement enables the positive electrode contact A11 and the negative electrode contact A12 to conduct on the same plane, that is, a height difference may not be formed between the positive electrode contact A11 and the negative electrode contact A12, which is beneficial to simplifying the design difficulty of the body 1.

[0040] In some embodiments, the charging base 2 is arranged to allow the body 1 to rotate circumferentially relative to the charging base 2 and charge the body 1 rotated to different angles. When specifically arranged, the axis of one of the positive electrode contact A11 and the negative electrode contact A12 may coincide with the axis of the body 1. Of course, on the premise of ensuring the use effect, the positive electrode contact A11 and the negative electrode contact A12 may also be arranged deviating from the axis of the body 1 respectively. However, the embodiments of the present application do not make any limitations in this regard.

[0041] In some embodiments, as Figure 1 and Figure 2 shown, a slot 25 is provided on the charging base 2, and the body 1 is inserted into the slot 25 during charging. When specifically arranged, the slot 25 may be surrounded by an annular protrusion on the first housing 23a, and the annular protrusion may be an integral structure with the outer housing 23 or an independent component installed on the outer housing 23. Such an arrangement can enable the charging contacts of the body 1 and the charging base 2 to be quickly aligned, which is beneficial to improving the convenience of operation. However, the embodiments of the present application do not make any limitations in this regard.

[0042] In some embodiments, the notch of the slot 25 is provided with a chamfer. With this arrangement, it is convenient to insert the body 1 into the slot 25, which is beneficial to improving the convenience of operation. However, the embodiments of the present application do not make any limitation in this regard.

[0043] In some embodiments, the charging base 2 is configured to be able to fix the body 1 during charging. With this arrangement, it is possible to avoid the problem that the body 1 shakes during charging, resulting in poor charging. However, the embodiments of the present application do not make any limitation in this regard.

[0044] In some embodiments, a magnetic adsorption structure is provided between the charging base 2 and the body 1. Optionally, both the charging base 2 and the body 1 are provided with magnetic components. When the charging base 2 charges the body 1, the body 1 can be fixed to the charging base 2 by adsorption through the magnetic components. However, the embodiments of the present application do not make any limitation in this regard.

[0045] In some embodiments, as Figure 1 shown, the magnetic adsorption structure includes a magnet 14. The magnet 14 is disposed on the body 1 and is used to adsorb the charging contact on the charging base 2 during charging. That is to say, the charging base 2 can use its charging contact as the magnetic component. In specific settings, the magnet 14 can be disposed inside the body 1 and at one end (i.e., the bottom end) of the body 1 close to the charging base 2. During use, the charging contact of the charging base 2 adsorbs to the magnet 14 on the body 1, thereby fixing the body 1 to the charging base 2. With this arrangement, the number of parts used can be reduced, and the production cost can be lowered. In addition, with the reduction of the number of parts, it is also beneficial to reduce the structural size of the charging base 2, making the charging base 2 convenient to carry and store. However, the embodiments of the present application do not make any limitation in this regard.

[0046] In some embodiments, the number of the magnets 14 is multiple, and the multiple magnets 14 are spaced apart circumferentially along the positive contact B21 or the negative contact B22. In specific settings, the number of the magnets 14 can be 3, and the 3 magnets 14 are opposite to the positive contact B21 and are spaced apart circumferentially along the positive contact B21. During use, the multiple magnets 14 can adsorb the positive contact B21 simultaneously, which can improve the fixing effect between the body 1 and the charging base 2 and make the body 1 more stable during charging. However, the embodiments of the present application do not make any limitation in this regard.

[0047] In some embodiments, the charging structure further includes a charging cable (not shown in the figure), and the charging cable is electrically connected to the charging base 2. In specific use, the charging base 2 can be connected to a power supply terminal through the charging cable to charge the body 1. However, the embodiments of the present application do not make any limitation in this regard.

[0048] In some embodiments, the charging cable and the charging base 2 are detachably connected. As Figure 2 and Figure 3As shown, in this embodiment, a USB interface 26 is provided on the side of the charging base 2, and the charging base 2 can be connected to a charging cable through the USB interface 26. This setting enables users to easily disassemble the charging cable, facilitating carrying and storage. Moreover, it is convenient to replace the charging cable, and different charging cables can be selected according to needs. However, the embodiments of this application do not make any limitations in this regard.

[0049] For the electric shaver with a charging structure provided by the embodiments of this application, one of the positive contact B21 and the negative contact B22 of the charging base 2 is annular and arranged around the other. With this setting, when the main body 1 rotates to different positions relative to the charging base 2, the conduction of the charging contacts can be achieved, such that the connection between the main body 1 and the charging base 2 is not limited to a unique position. This can make the connection and disconnection between the main body 1 and the charging base 2 more flexible and convenient, thereby improving the technical problem in the prior art that it is rather inconvenient to connect and disconnect the shaver main body 1 and the charging base 2, resulting in a poor user experience.

[0050] It should be noted that for the electric shaver involved in this application, the number of cutter heads of the shaver is not limited. For example, the number of cutter heads of the electric shaver can be one, two, three, or more than three. Only one type is selected in this embodiment for illustration, rather than for limiting the protection scope of this application.

[0051] One or more embodiments of this specification are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification shall be included within the protection scope of this application.

[0052] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any person skilled in the art within the technical scope disclosed by this application can easily think of changes or substitutions, which should all be covered within the protection scope of this application. Therefore, the protection scope of this application shall be subject to the protection scope of the claims.
