[0045] In order to enable those skilled in the art to better understand the embodiments of the present application, the personal care equipment involved in the embodiments of the present application is first described.

[0046] The personal care devices involved in this application can be understood as personal care devices such as electric toothbrushes, skin care devices, and water flossers. Figure 1 As shown, the personal care device includes a handle portion 100 and a care head 200. The handle portion 100 can be understood as the part held by the user during the operation of the personal care device, and the care head 200 can be understood as the part of the personal care device used to care for the user, such as a toothbrush head, a skin care head, a nozzle, etc.

[0047] In some embodiments, Figure 1 As shown, the personal care device also includes a care bottle 300, which can be understood as a device of the personal care device for storing consumables such as toothpaste, skin care products, and mouthwash.

[0048] Among them, the consumable output end of the care bottle 300 can be connected to the input end of the consumable driving component such as the peristaltic pump of the handle part 100, so that the consumable driving component such as the peristaltic pump can transport the consumables in the care bottle 300 to the care head 200, thereby meeting the consumable needs of the care head 200 during the care process.

[0049] like Figures 2 to 7 As shown, an embodiment of the present application provides a personal protection device, including a first component 10, a second component 20, a rotating member 30 and a connecting structure 40, wherein the rotating member 30 is rotatably disposed between the first component 10 and the second component 20;

[0050] When the rotating member 30 is rotated relative to the first component 10 and / or the second component 20 , the first component 10 and the second component 20 are connected together through the connecting structure 40 .

[0051] The rotating member 30 is rotated relative to the first component 10 and / or the second component 20. It can be understood that the rotating member 30 can rotate relative to the first component 10, or that the rotating member 30 can rotate relative to the second component 20, or that the rotating member 30 can rotate relative to the first component 10 and the second component 20 at the same time.

[0052] In some embodiments, when the rotating member 30 can only rotate relative to the first component 10, the rotating member 30 can be first connected to the second component 20, and the connected rotating member 30 and the second component 20 can be rotatably connected to the first component 10 as a whole, so that the relative rotation of the rotating member 30 and the first component 10 can drive the connecting structure 40 to connect the first component 10 and the second component 20 together.

[0053] In which, when the rotating member 30 can only rotate relative to the first component 10, the connecting structure 40 may include a first connecting portion arranged on the rotating member 30, and a second connecting portion arranged on the first component 10, and the first component 10 and the second component 20 are connected together through the connection between the first connecting portion and the second connecting portion.

[0054] In some embodiments, when the rotating member 30 can only rotate relative to the second member 20, the rotating member 30 can be first connected to the first member 10, and the connected rotating member 30 and the first member 10 can be rotatably connected to the second member 20 as a whole, so that the relative rotation of the rotating member 30 and the second member 20 can drive the connecting structure 40 to connect the first member 10 and the second member 20 together.

[0055] In which, when the rotating member 30 can only rotate relative to the second member 20, the connecting structure 40 may include a third connecting portion arranged on the rotating member 30, and a fourth connecting portion arranged on the second member 20, and the first member 10 and the second member 20 are connected together through the connection between the third connecting portion and the fourth connecting portion.

[0056] In some embodiments, when the rotating member 30 can rotate relative to the first component 10 and the second component 20 at the same time, the connecting structure 40 can be driven to connect the first component 10 and the second component 20 together through the relative rotation of the rotating member 30 and the first component 10 and the second component 20.

[0057] In which, when the rotating member 30 can rotate relative to the first component 10 and the second component 20 at the same time, the connecting structure 40 may include a fifth connecting portion and an eighth connecting portion arranged on the rotating member 30, a sixth connecting portion arranged on the first component 10, and a seventh connecting portion arranged on the second component 20. The first component 10 and the second component 20 are connected together through the connection between the fifth connecting portion and the sixth connecting portion and the seventh connecting portion and the eighth connecting portion.

[0058] It should be noted that the rotating member 30 can also be used to connect the first component 10 or the second component 20 together first, for example, by means of a sliding connection. After the rotating member 30 and the first component 10 or the second component 20 are first slidably connected, the rotating member 30 is provided with a ninth connection portion, and the other of the first component 10 and the second component 20 is correspondingly provided with a tenth connection portion. The rotating member 30 is rotated, and the rotating member 30 is rotated in the sliding groove relative to the first component 10 or the second component 20 that is connected first, and is rotated relative to the other of the first component 10 and the second component 20, and the first component and the second component are connected together through the ninth connection portion and the tenth connection portion.

[0059] It can be understood that the rotating member 30 rotates relative to the first component 10 and the second component 20 at the same time. When the first component 10 and the second component 20 are connected together by the connecting structure 40, the first component 10, the second component 20 and the rotating member 30 can all be independent components. The first component 10 and the second component 20 are connected to the rotating member 30 simultaneously or successively, and then the rotating member 30 is rotated in the direction of fixing the two, so that the two are fixedly connected together.

[0060] In some embodiments, the connection structure 40 includes a first connection member 41 and a second connection member 42 . The first connection member 41 is disposed on the rotating member 30 , and the second connection member 42 is disposed on the first component 10 and / or the second component 20 .

[0061] Among them, the first connection part, the third connection part, the fifth connection part, the eighth connection part and the ninth connection part arranged on the rotating part 30 correspond to the first connection part 41, and the second connection part, the fourth connection part, the sixth connection part, the seventh connection part and the tenth connection part arranged on the first component 10 or the second component 20 correspond to the second connection part 42.

[0062] In this embodiment, a rotatable rotating member 30 is provided between the first component 10 and the second component 20, and the rotating member 30 is rotated relative to the first component 10 and / or the second component 20 to drive the connecting structure 40 to connect the first component 10 and the second component 20 together. This can effectively achieve a fixed connection between the first component 10 and the second component 20. Compared with directly achieving a fixed connection between the first component and the second component through the relative rotational movement of the first component 10 and the second component, the user's sense of use is improved, and the relative rotational movement of the first component 10 and the second component 20 is avoided. The influence of the sealing of the connecting point between the first component 10 and the second component 20 is avoided, and the sealing connection effect of the first component 10 and the second component 20 is effectively improved.

[0063] In addition, when personal care equipment includes multiple flow channels to transport different consumables, it also avoids contamination between different consumables, which may lead to problems such as liquid cross-contamination.

[0064] It should be noted that the rotation described in the present application can be understood as rotation, which includes clockwise and counterclockwise rotation. Whether the first component 10 and the second component 20 are fixedly connected in the clockwise direction or the counterclockwise direction is determined according to the needs of the actual scenario and is not limited here.

[0065] Moreover, since the first component 10 and / or the second component 20 does not rotate along with the rotating member 30 during the rotational movement of the rotating member 30, the user's experience of using the personal protection device can be enhanced.

[0066] In some embodiments, the first component 10 can be understood as one of the handle 100 and the nursing bottle 300 of the personal care device, and the second component 20 can be understood as the other of the handle 100 and the nursing bottle 300 of the personal care device, so as to realize the need for conveying consumables between the handle 100 and the nursing bottle 300. For example, when the first component 10 is the handle 100 of the personal care device, the second component 20 is the nursing bottle 300 of the personal care device; for another example, when the first component 10 is the nursing bottle 300 of the personal care device, the second component 20 is the handle 100 of the personal care device.

[0067] In some embodiments, the first component 10 can be understood as one of the handle 100 and the care head 200 of the personal care device, and the second component 20 can be understood as the other of the handle 100 and the care head 200 of the personal care device, so as to realize the need for conveying consumables between the handle 100 and the care head 200. For example, when the first component 10 is the handle 100 of the personal care device, the second component 20 is the care head 200 of the personal care device; for another example, when the first component 10 is the care head 200 of the personal care device, the second component 20 is the handle 100 of the personal care device.

[0068] In some embodiments, when the handle portion 100 of the personal care device includes an upper handle and a lower handle, the first component 10 can be understood as one of the upper handle and the lower handle, and the second component 20 can be understood as the other of the upper handle and the lower handle, so as to realize the need for conveying consumables between the upper handle and the lower handle. For example, when the first component 10 is the upper handle of the personal care device, the second component 20 is the lower handle of the personal care device; for another example, when the first component 10 is the lower handle of the personal care device, the second component 20 is the upper handle of the personal care device.

[0069] The upper handle may be understood as the portion of the handle portion 100 connected to the care head 200 ; the lower handle may be understood as the portion of the handle portion 100 connected to the care bottle 300 .

[0070] It should be noted that in Figures 2 to 7In the figure, the handle part of the personal care device is used as the first component 10, and the nursing bottle of the personal care device is used as the second component 20 to specifically illustrate the personal care device provided in the embodiment of the present application.

[0071] In some embodiments, the rotating member 30 is provided with a through hole 31 penetrating the first end and the second end, and the first end and the second end are two opposite ends of the rotating member 30;

[0072] The connecting structure 40 includes a first connecting member 41 arranged on the rotating member 30, and a second connecting member 42 arranged on the first component 10 and / or the second component 20 and adapted to the first connecting member 41; wherein, when the rotating member 30 is rotated relative to the first component 10 and / or the second component 20, the first component 10 and the second component 20 are connected together through the connecting members of the first connecting member 41 and the second connecting member 42.

[0073] In this embodiment, the first connecting member 41 can be arranged on the outer side wall of the rotating member 30, or on the inner side wall of the rotating member 30, where the inner wall is the side adjacent to the through hole; accordingly, the second connecting member 42 can be arranged on the inner side wall of the first component 10 and / or the second component 20, or on the outer side wall of the first component 10 and / or the second component 20, or the second connecting member 42 arranged on one of the first component 10 and the second component 20 can be arranged on the inner side wall of the component, and the other second connecting member 42 can be arranged on the outer side wall of the other component. Correspondingly, the outer side wall and the inner side wall of the rotating member 30 are provided with corresponding first connecting members 41 to meet the connection requirements of the first component 10 and the second component 20 with different structural designs.

[0074] In some embodiments, when the first connecting member 41 is disposed on the outer wall of the rotating member 30 and the second connecting member 42 is disposed on the inner wall of the first component 10 and / or the second component 20, one end of the first component 10 and / or the second component 20 adjacent to the rotating member 30 can be sleeved on part of the rotating member 30 to meet the connection between the rotating member 30 and the first component and / or the second component 20.

[0075] In some embodiments, when the first connecting member 41 is disposed on the inner wall of the rotating member 30 and the second connecting member 42 is disposed on the outer wall of the first component 10 and / or the second component 20, the rotating member 30 can be sleeved on the first component 10 and / or the second component 20, or the first component 10 and / or the second component 20 can be inserted into the through hole 31 of the rotating member 30 and satisfy the connection between the rotating member 30 and the first component and / or the second component 20.

[0076] In some embodiments, a second connecting member 42 is provided on the inner wall of the first component 10, a second connecting member 42 is provided on the outer wall of the second component 20, a first connecting member 41 is provided on the outer wall of one end of the rotating member 30 corresponding to the first component 10, and a first connecting member 41 is provided on the inner wall of one end of the rotating member 30 corresponding to the second component 20, a portion of the first component 10 adjacent to one end of the rotating member 30 can be sleeved on part of the rotating member 30, a portion of the second component 20 adjacent to the other end of the rotating member 30 can be inserted into the through hole 31 of the rotating member 30, and by rotating the rotating member in the direction of fixing the first component 10 and the second component 20, the rotating member rotates relative to the first component 10 and the second component 20, thereby fixing the first component 10 and the second component 20 together.

[0077] In some embodiments, the first component 10 is connected to the first end of the rotating member 30, and the second component 20 can be inserted into the through hole 31 at the second end of the rotating member 30; or, the first component 10 and the second component 20 can be inserted into the through hole 31 at the first end of the rotating member 30 and the second end of the rotating member 30, respectively;

[0078] The rotating member 30 is used to connect the first connecting member 41 and the second connecting member 42 by rotating the rotating member 30 when the first interface portion 11 of the first component 10 and the second interface portion 21 of the second component 20 are connected in the through hole 31, so as to connect the first component 10 and the second component 20 together.

[0079] The first interface portion 11 of the first component 10 and the second interface portion 21 of the second component 20 are connected in the through hole 31. It can be understood that the first interface portion 11 of the first component 10 and the second interface portion 21 of the second component 20 can both be inserted into the through hole 31 of the rotating part 30, and the first interface portion 11 of the first component 10 and the second interface portion 21 of the second component 20 can be connected in the through hole 31, thereby meeting the transportation requirements of consumables in the first component 10 and the second component 20.

[0080] In some embodiments, the first interface portion 11 of the first component 10 can be inserted into the through hole 31 at the first end of the rotating component 30, and the second interface portion 21 of the second component 20 can be inserted into the through hole 31 at the second end of the rotating component 30, thereby satisfying the connection requirement between the first interface portion 11 of the first component 10 and the second interface portion 21 of the second component 20 in the through hole 31.

[0081] It should be noted that during the relative rotation of the rotating member 30, the first component 10 and / or the second component 20 will not rotate with the rotating member 30, that is, during the relative rotation of the rotating member 30, the relative rotation of the first interface portion 11 of the first component 10 and the second interface portion 21 of the second component 20 caused by the relative rotation of the first component 10 and the second component 20 can be effectively avoided, and the sealing effect of the connection between the first interface portion 11 of the first component 10 and the second interface portion 21 of the second component 20 is effectively improved. For example, when the first component 10 is the handle portion 100 and the second component 20 is the nursing bottle 300, the first interface portion 11 corresponds to the inlet portion of the consumables, and the second interface portion 21 is the outlet portion of the consumables provided on the nursing bottle 300. The handle portion 100 and the nursing bottle 300 are connected by rotating the rotating member 30, so as to avoid the relative rotation of the outlet portion and the inlet portion, and improve the sealing effect.

[0082] Among them, for the rotating part 30 that connects the first component 10 and the second component 20 in a manner of rotating relative to the first component 10 or the second component 20, the second interface part 21 can be set to be inserted into the first interface part 11 in a protruding manner, thereby improving the sealing effect; and for the manner in which the rotating part 30 rotates relative to the first component 10 and the second component 20, if the second interface part 21 is set to be inserted into the first interface part 11 in a protruding manner, the sealing effect is better than the manner in which it is not set to be protruding.

[0083] In some embodiments, the rotation of the rotating member 30 can be understood as a left-handed motion or a right-handed motion of the rotating member 30. One of the left-handed motion or the right-handed motion of the rotating member 30 can realize a fixed connection between the first component 10 and the second component 20, and the other can realize a separation between the first component 10 and the second component 20, that is, release the fixed connection between the first component 10 and the second component 20.

[0084] For example, during the counterclockwise movement of the rotating member 30 relative to the first component 10 and / or the second component 20 , the first connecting member 41 and the second connecting member 42 can be connected, thereby achieving the connection between the first component 10 and the second component 20 .

[0085] Accordingly, during the right-handed movement of the rotating member 30 relative to the first component 10 and / or the second component 20 , the first connecting member 41 and the second connecting member 42 can be disengaged, thereby achieving the disengagement of the first component 10 and the second component 20 .

[0086] In some embodiments, the left-handed motion may be understood as the rotating member 30 rotating in a first direction, and the right-handed motion may be understood as the rotating member 30 rotating in a second direction, and the first direction is opposite to the second direction.

[0087] In some embodiments, the first direction may be a clockwise direction, and the second direction may be a counterclockwise direction; or, the first direction may be a counterclockwise direction, and the second direction may be a clockwise direction.

[0088] The connection between the first connecting member 41 and the second connecting member 42 may be a clamping fixation of a clamping groove and a buckle, or a threaded connection of an internal thread and an external thread.

[0089] In this embodiment, the first interface portion 11 of the first component 10 and the second interface portion 21 of the second component 20 are connected and arranged in the through hole 31, and the first component 10 and the second component 20 are fixedly connected through the relative rotation of the rotating member 30; compared with achieving the fixed connection between the first component and the second component through the relative rotational movement of the first component and the second component, the user's sense of use is improved, and the relative rotational movement of the first component 10 and the second component 20 is effectively avoided, thereby avoiding the relative rotational movement of the first interface portion 11 of the first component 10 and the second interface portion 21 of the second component 20 caused by the relative rotational movement of the first component 10 and the second component 20, and effectively improving the sealing effect of the connection between the first interface portion 11 of the first component 10 and the second interface portion 21 of the second component 20, that is, effectively improving the sealing connection effect of the first component 10 and the second component 20.

[0090] Moreover, since the setting of the rotating part 30 can avoid the relative rotational movement between the first interface part 11 of the first component 10 and the second interface part 21 of the second component 20, the contamination effect of the consumables flowing through the connecting point of the first interface part 11 of the first component 10 and the second interface part 21 of the second component 20 on the connecting point of the first interface part 11 of the first component 10 and the second interface part 21 of the second component 20 can also be reduced.

[0096] Among them, the card slot structure and the buckle structure can be snapped and fixed during the rotation of the rotating part 30; for example, the card slot structure and the buckle structure can be snapped and fixed during the left rotation of the rotating part 30; for another example, the card slot structure and the buckle structure can be unlocked and disengaged during the right rotation of the rotating part 30.

[0097] In some embodiments, Figure 6 and Figure 7 As shown, the slot structure includes a first slot 411 and a second slot 412 that are interconnected, and the first slot 411 is arranged along the axial direction of the through hole 31, and the second slot 412 is arranged along the circumferential direction of the through hole 31;

[0098] The buckle structure can be moved along the first slot 411 to the second slot 412 , and after the buckle structure moves to the second slot 412 , the slot structure and the buckle structure can be fixed by rotating the rotating member 30 .

[0099] In this embodiment, the movement of the snap structure in the first slot 411 can be achieved by pushing and pulling the second component 20; and after the snap structure moves to the second slot 412, the movement of the snap structure in the second slot 412 can be achieved by rotating the rotating member 30, thereby achieving the snap-fit ​​fixation of the slot structure and the snap structure, and achieving a fixed connection between the first component 10 and the second component 20.

[0100] In some embodiments, the first connecting member 41 is one of an external thread and an internal thread, and the second connecting member 42 is the other of an external thread and an internal thread, so that the first component 10 and the second component 20 are connected by a threaded connection of the external thread and the internal thread.

[0101] In some embodiments, Figure 5 As shown, the second component 20 is provided with a panel structure 22 adapted to the through hole 31 , the panel structure 22 is arranged around the second interface portion 21 , and the second connecting member 42 is arranged on the outer peripheral surface of the panel structure 22 .

[0102] In this embodiment, by providing a surrounding plate structure 22 around the second interface portion 21 on the second component 20, the sealing connection effect at the connection point between the first interface portion 11 of the first component 10 and the second interface portion 21 of the second component 20 can be further improved.

[0103] In some embodiments, the personal protection device further includes a seal, and the first component 10 and the first end of the rotating component 30 can be sealed and connected via the seal to further enhance the sealing connection effect between the first component 10 and the second component 20 .

[0105] Among them, when the second component 20 is a nursing bottle of personal care equipment, the multiple second interface parts 21 can be understood as multiple bottle openings of the nursing bottle, and multiple consumable spaces corresponding to the multiple bottle openings can be set in the nursing bottle to meet the storage needs of different types of consumables.

[0106] Correspondingly, when the first component 10 is a handle portion of a personal protective equipment, the multiple first interface portions 11 can be understood as multiple consumable inlets of the handle portion to meet the transportation requirements of different types of consumables.

[0107] In some embodiments, the personal protection device also includes a locking structure, and the rotating member 30 is locked and connected to the first component 10 and / or the second component 20 through the locking structure; when the locking structure is in a locked state, the rotating member 30 is locked and connected to the first component 10 and / or the second component 20; when the locking structure is in an unlocked state, the rotating member 30 can rotate relative to the first component 10 and / or the second component 20.

[0108] In this embodiment, a locking structure is provided to achieve a locked connection between the rotating member 30 and the first component 10 and / or the second component 20 , thereby preventing the influence of misoperation of the rotating member 30 on the sealed connection between the first component 10 and the second component 20 .

[0109] In some embodiments, the unlocking state and the locking state of the locking structure can be switched by pushing up or pulling down the rotating member 30 relative to the first component 10 and / or the second component 20 .
