The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that the personal care device of the embodiment of the present invention is a shaver, wherein the care head 20 is the cutter head of the shaver, and the care main unit 10 is the main unit (handle) of the shaver.

[0033] like Figures 1 to 12As shown, an embodiment of the utility model provides a personal care device. The personal care device includes a care host 10, a care head 20 and an electrical connection part. Among them, the care host 10 has a power supply component; the care head 20 has a component to be powered, one of the care host 10 and the care head 20 includes a first connection component 11 with a first connection axis L1, and the other of the care host 10 and the care head 20 includes a second connection component 21 with a second connection axis L2, and the first connection component 11 and the second connection component 21 are configured to be able to approach and connect to each other by aligning the first connection axis L1 and the second connection axis L2; ​​the electrical connection part includes a first electrical connector 51 and a second electrical connector 52, the second electrical connector 52 is provided on the care host 10 and is electrically connected to the power supply component, the first electrical connector 51 is provided on the care head 20 and is electrically connected to the component to be powered, and the electrical connection part has a conductive state in which the first electrical connector 51 and the second electrical connector 52 are in contact with each other, and a power-off state in which the first electrical connector 51 and the second electrical connector 52 are separated from each other.

In this way, on the one hand, compared with the prior art that uses a wire to electrically connect the component to be powered and the power supply component, in the utility model, by setting the electrical connection part, the care host 10 and the care head 20 can be easily disassembled; on the other hand, by setting the electrical connection part, it is possible to avoid setting an induction coil to achieve the electrical connection between the component to be powered and the power supply component, thereby avoiding increasing the volume of the care head 20 and / or the care host 10.

[0035] like Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, in the embodiment of the utility model, the first electrical connector 51 is a cylindrical structure having a connecting cavity 511, and the extension direction of the cylindrical structure is the same as the extension direction of the first connection axis L1 or the second connection axis L2. The second electrical connector 52 has a connector 521. When the first connection component 11 and the second connection component 21 are connected to each other, at least part of the connector 521 is located in the connecting cavity 511, so that the electrical connection part is in a conducting state. In this way, contact and conduction between the first electrical connector 51 and the second electrical connector 52 can be achieved, and the radial movement of the care host 10 and the care head 20 can be further restricted, thereby strengthening the connection between the care host 10 and the care head 20.

[0036] Specifically, in the embodiment of the present invention, the first electrical connector 51 is cylindrical; the second electrical connector 52 is cylindrical.

[0037] Specifically, in the embodiment of the present invention, there are multiple first electrical connectors 51, and there are also multiple corresponding second electrical connectors 52.

The number of the first electrical connectors 51 is preferably 4, and the number of the corresponding second electrical connectors 52 is also preferably 4.

[0038] like Fig. 9 As shown, in the embodiment of the present invention, at least part of the connector 521 is a frustum section, so that it is convenient for the connector of the second electrical connector 52 to enter the connection cavity 511 of the first electrical connector 51 .

[0039] like Figure 3 As shown, in the embodiment of the utility model, the length of the connector 521 in the connection cavity 511 is greater than or equal to 1 mm and less than or equal to 10 mm. In this way, the first electrical connector 51 and the second electrical connector 52 can overlap in the axial direction, so that the power supply component can be safely, stably and reliably powered.

[0040] Preferably, in the embodiment of the present invention, the first electrical connector 51 and the second electrical connector 52 have an overlapped portion of 2 mm to 3 mm in the axial direction.

[0041] like Figure 7 As shown, in the embodiment of the present invention, the first electrical connector 51 is provided with an adjustment gap 53 communicating with the connection cavity 511 , and the adjustment gap 53 penetrates the first electrical connector 51 along the axial direction of the cylindrical structure.

[0042] Through the above arrangement, the first electrical connector 51 can be deformed by external force and the size of the adjustment gap 53 can be changed, so that the first electrical connector 51 can still be installed to the first connecting component 11 when there is a manufacturing tolerance, and at the same time, the contact connection between the first electrical connector 51 and the second electrical connector 52 is facilitated.

[0043] Specifically, in the embodiment of the present invention, the adjustment gap 53 penetrates the inner wall and the outer wall of the cylindrical structure along the radial direction of the cylindrical structure.

The support member 54 is an elastic member configured to press the first electrical connector 51 against the second electrical connector 52 .

[0045] Through the above arrangement, the elastic force of the elastic member can make the first electrical connector 51 and the second electrical connector 52 tend to be in close contact with each other, so that the first electrical connector 51 and the second electrical connector 52 can maintain a reliable electrical connection.

[0046] In one embodiment, the first electrical connector 51 may be an elastic member, and the support member 54 is not provided, so that the first electrical connector 51 is directly pressed against the second electrical connector 52.

In this way, when the first connection part 11 and the second connection part 21 are connected, the first electrical connector 51 and the second electrical connector 52 can contact and conduct electricity.

[0049] Furthermore, in addition to the cooperation and positioning of the first electrical connector 51 and the second electrical connector 52 themselves, the cooperation of the first connecting component 11 and the second connecting component 21 further defines the relative position of the first electrical connector 51 and the second electrical connector 52, thereby ensuring reliable electrical connection.

[0050] like Figure 6 As shown, in the embodiment of the utility model, the installation cavity 55 includes a first cavity section 551, a reduced diameter section 552 and a second cavity section 553 which are sequentially connected along the first connecting axis L1, and the cross-sections of the first cavity section 551 and the second cavity section 553 are both larger than the cross-section of the reduced diameter section 552; the first electrical connector 51 is provided with a first limit member 56 and a second limit member 57, and the first limit member 56 and the second limit member 57 are spaced apart along the first connecting axis L1, the first limit member 56 is limitedly matched with the first cavity section 551, and the second limit member 57 is limitedly matched with the second cavity section 553.

[0051] In the above technical solution, the first limiting member 56 cooperates with the first cavity section 551 to limit the first electrical connector 51 in the Figure 6 The first connecting member 11 is separated from the first connecting member 11 from top to bottom, and the second limiting member 57 is limited in cooperation with the second cavity section 553, so as to limit the first electrical connector 51 in Figure 6 The first connecting member 11 is disengaged from bottom to top, thereby installing the first electrical connector 51 into the installation cavity 55 .

[0052] Specifically, in the embodiment of the present invention, there is a step surface between the first cavity section 551 and the reduced diameter section 552, and the cross-sectional area of ​​the first limiter 56 is larger than the cross-sectional area of ​​the reduced diameter section 552, so that the step surface can limit the first electrical connector 51 in Figure 6 The first connecting member 11 is disengaged from top to bottom.

[0053] like Figure 7 and Figure 8 As shown, in the embodiment of the utility model, the second limit member 57 is an elastic arm, and the first electrical connector 51 is provided with a void groove 58 connected to the connecting cavity 511, and the elastic arm is obliquely arranged in the void groove 58. From the first limit member 56 to the second limit member 57, the distance between the elastic arm and the axis of the tubular structure gradually decreases; under the action of external force, the elastic arm has a first position protruding from the first electrical connector 51 and a second position received in the void groove 58.

[0054] In the above technical solution, the second stopper 57 protrudes outward from the first electrical connector 51 and can be deformed under the action of external force. Figure 8 The first electrical connector 51 in the Figure 6In the installation cavity 55 shown, when passing through the reduced diameter section 552, the second limit member 57 is deformed by the pressure of the inner wall of the reduced diameter section 552, and the second limit member 57 is retracted inward to the air avoidance groove 58. After leaving the reduced diameter section, the squeezing pressure of the inner wall of the reduced diameter section 552 on the second limit member 57 disappears, and the second limit member 57 is deformed under the action of its own elastic force and bulges outward again, thereby abutting against the step surface formed between the second cavity section 553 and the reduced diameter section 552, so as to limit the first electrical connector 51 from being separated from the first connecting component 11 from bottom to top.

[0055] Preferably, in the embodiment of the present utility model, there may be two second limiting members 57 symmetrically distributed on the outer peripheral surface of the first electrical connector 51 .

[0056] In one embodiment, the first electrical connector 51 may be installed in the installation cavity 55 by pre-embedded injection molding.

In this way, the displacement of the second electrical connector 52 on the second connecting axis L2 can be limited, so that the second electrical connector 52 is fixed to the nursing host 10.

After the applied pressure is removed, the elastic component 82 will be restored to its original position.

[0067] Preferably, in the embodiment of the present invention, the elastic member 82 is a coil spring.
