[0057] In order to enable those skilled in the art to better understand the embodiments of the present application, the personal protection equipment involved in the embodiments of the present application is first described.

[0058] 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, such as Figure 1 and Figure 2 As shown, the personal care device mainly consists of a handle 100 and a care head 200. The handle 100 can be understood as the part of the personal care device that is held by the user during operation, 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 or a skin care head. Consumables can be toothpaste, skin care products, mouthwash, etc.

[0059] like Figures 2 to 6 As shown, an embodiment of the present application provides a consumable material delivery assembly of a personal care device, which is used to deliver consumable materials such as toothpaste and skin care products to the care head 200 for the care head 200 to perform care operations.

[0060] In the present application, the above-mentioned consumable conveying assembly includes a driving pump 10, a hollow shaft motor 20 and a first conveying tube 31, and the consumable conveying assembly consisting of at least the driving pump 10, the hollow shaft motor 20 and the first conveying tube 31 can be arranged on the handle part 100, that is, the consumable conveying assembly consisting of at least the driving pump 10, the hollow shaft motor 20 and the first conveying tube 31 can be understood as a structural component arranged on the handle part 100.

[0061] The driving pump 10 can be understood as a driving device for driving and delivering pastes such as toothpaste and skin cream, such as a peristaltic pump, an air pump, a rotor pump, etc.

[0062] The above-mentioned hollow shaft motor 20 includes a hollow shaft 21, that is, the output shaft of the hollow shaft motor 20 is a hollow shaft; and the above-mentioned care head 200 can be connected to the hollow shaft 21, so that the hollow shaft motor 20 can drive the care head 200 to vibrate, swing or rotate or other at least one of the movements, thereby enabling the vibration, swing or rotation of the care head 200 to perform corresponding care operations.

[0063] The hollow shaft motor 20 may be a sonic motor, a brushless motor, a servo motor, etc., which is not limited here.

[0064] The hollow shaft 21 further has a hollow flow channel 211, and the hollow flow channel 211 can be understood as a hollow structure provided through the hollow shaft 21. The hollow flow channel 211 can be a flow channel structure formed through both end surfaces of the hollow shaft 21, so that consumables can be delivered to the care head 200 through the hollow flow channel 211.

[0065] In some embodiments, the first end of the first delivery tube 31 is connected to the first consumable material output port of the driving pump 10 , and the second end of the first delivery tube 31 is set through the hollow flow channel 211 and connected to the above-mentioned care head 200 .

[0066] The second end of the above-mentioned first conveying pipe 31 is arranged to pass through the hollow flow channel 211. It can be understood that when the consumables are conveyed through the hollow flow channel 211, they are conveyed through the conveying pipe section of the first conveying pipe 31 located in the hollow flow channel 211, that is, when the consumables are conveyed through the hollow flow channel 211, the consumables will not contact the inner wall of the hollow flow channel 211, but will be conveyed by the conveying flow channel of the first conveying pipe 31.

[0067] In this embodiment, the first delivery tube 31 is arranged to pass through the hollow channel 211 so that the consumables can be directly delivered from the first consumables output port of the drive pump 10 to the care head 200 through the first delivery tube 31, thereby avoiding contact between the consumables and the inner wall of the hollow channel 211 and reducing the pollution effect of the consumables on the hollow channel 211 during the process of being delivered through the hollow channel 211.

[0068] Moreover, by setting the first delivery tube 31 through the hollow channel 211, the consumables can be directly delivered from the first consumables output port of the driving pump 10 to the care head 200 through the first delivery tube 31. Compared with first delivering the consumables through the first delivery tube 31 to the hollow channel 211 and then delivering them to the care head 200 from the hollow channel 211, at least one adapter can be reduced, thereby effectively improving the sealing effect of the consumables delivery path.

[0069] The second end of the first delivery tube 31 is disposed through the hollow channel 211 and is connected to the care head 200. It can be understood that after passing through the hollow channel 211, the second end of the first delivery tube 31 can be connected to the consumables input port of the care head 200. The consumables input port of the care head 200 can be understood as the entrance or input port for consumables to enter the care head 200.

[0070] In some embodiments, the consumable delivery assembly further includes a second delivery tube 32 , a first end of the second delivery tube 32 being connected to the second consumable output port of the drive pump 10 , and a second end of the second delivery tube 32 being connected to the consumable input port of the care head 200 .

[0071] In this embodiment, the consumable material conveying assembly may have two conveying pipes to improve the conveying efficiency of the consumable materials.

[0072] Moreover, by setting up two delivery pipes, two different consumables can be delivered at the same time to meet the usage requirements of different delivery scenarios.

[0073] In some embodiments, the second delivery tube 32 can be arranged around the hollow shaft motor 20, that is, the second delivery tube 32 is not arranged through the hollow flow channel 211, but is connected to the consumables input port of the care head 200 to reduce the impact of the movement of the hollow shaft motor 20 on the second delivery tube 32.

[0074] In some embodiments, the second end of the second delivery tube 32 may also be disposed through the hollow flow channel 211 and communicated with the consumables input port of the care head 200 .

[0075] Among them, the first conveying pipe 31 includes a first conveying pipe section 311, which is the conveying pipe section of the first conveying pipe 31 located in the hollow flow channel 211; the second conveying pipe 32 includes a second conveying pipe section 321, which is the conveying pipe section of the second conveying pipe 32 located in the hollow flow channel 211.

[0076] In this embodiment, by setting both conveying pipes of the consumable material conveying assembly through the hollow flow channel 211, that is, by setting both the first conveying pipe 31 and the second conveying pipe 32 through the hollow flow channel 211, not only can the consumable material conveyed through the first conveying pipe 31 be prevented from contacting the inner wall of the hollow flow channel 211, but the consumable material conveyed through the second conveying pipe 32 can also be prevented from contacting the inner wall of the hollow flow channel 211, thereby reducing the pollution effect of the consumable material on the hollow flow channel 211 during the process of being conveyed through the hollow flow channel 211.

[0077] In some embodiments, the first delivery tube 31 can be used to deliver the first consumable, and the second delivery tube 32 can be used to deliver the second consumable, and the first consumable and the second consumable are different consumables to reduce mutual contamination of different types of consumables during the delivery process.

[0078] In some embodiments, the first delivery tube 31 and the second delivery tube 32 may also deliver the same consumable material to improve the delivery efficiency of the consumable material.

[0079] Among them, the above-mentioned first delivery pipe 31 also includes a fourth delivery pipe section, which is the delivery pipe section of the first delivery pipe 31 used to connect the first consumables output port of the driving pump 10 and the first delivery pipe section 311; the above-mentioned second delivery pipe 32 also includes a fifth delivery pipe section, which is the delivery pipe section of the second delivery pipe 32 used to connect the second consumables output port of the driving pump 10 and the second delivery pipe section 321.

[0080] The first conveying pipe section 311 and the second conveying pipe section 321 may be arranged in parallel, intertwined, or nested within the hollow channel 211 to form a channel for conveying consumables.

[0081] In some embodiments, as Figure 7 As shown, the first conveying pipe section 311 and the second conveying pipe section 321 are sub-flow channels distributed in parallel in the hollow flow channel 211 .

[0082] The above-mentioned first conveying pipe section 311 and second conveying pipe section 321 are sub-channels distributed in parallel in the hollow flow channel 211. It can be understood that the first conveying pipe section 311 and the second conveying pipe section 321 are independently arranged in the hollow flow channel 211. For example, the first conveying pipe section 311 and the second conveying pipe section 321 can be arranged side by side in the hollow flow channel 211, or the first conveying pipe section 311 and the second conveying pipe section 321 can be distributed in the hollow flow channel 211 in a double helix pattern.

[0083] In some embodiments, the first conveying pipe section 311 and the second conveying pipe section 321 can be distributed in the hollow flow channel 211 and intertwined with each other, and form sub-flow channels that are intertwined and arranged side by side in the hollow flow channel 211, so as to respectively convey the consumables conveyed through the first conveying pipe 31 and the consumables conveyed through the second conveying pipe 32.

[0084] In some embodiments, as Figure 8 As shown, the first conveying pipe section 311 is sleeved on the second conveying pipe section 321, and a first gap flow channel 41 is formed between the inner tube wall of the first conveying pipe section 311 and the outer tube wall of the second conveying pipe section 321. The first gap flow channel 41 is used to convey the consumables conveyed through the first conveying pipe 31.

[0085] In some embodiments, as Figure 9 and Figure 10 As shown, the consumables delivery assembly further includes a third delivery tube 33 , a first end of the third delivery tube 33 being connected to the third consumables output port of the drive pump 10 , and a second end of the third delivery tube 33 being connected to the consumables input port of the care head 200 .

[0086] In this embodiment, the consumable material conveying assembly may have three conveying pipes to improve the conveying efficiency of the consumable materials.

[0087] Moreover, by setting up three conveying pipes, at least two different consumables can be conveyed at the same time, reducing the mutual contamination of different types of consumables during the conveying process and meeting the usage requirements of different conveying scenarios.

[0088] In some embodiments, the third delivery tube 33 can be arranged around the hollow shaft motor 20, that is, the third delivery tube 33 is not arranged through the hollow flow channel 211, and is connected to the consumables input port of the care head 200 to reduce the impact of the movement of the hollow shaft motor 20 on the third delivery tube 33.

[0089] In some embodiments, the second end of the third delivery tube 33 is disposed through the hollow flow channel 211 and communicates with the consumables input port of the care head 200 ;

[0090] The third delivery pipe 33 includes a third delivery pipe section 331 , and the third delivery pipe section 331 is the delivery pipe section of the third delivery pipe 33 located in the hollow flow channel 211 .

[0091] In this embodiment, by setting the three conveying pipes of the consumable material conveying assembly through the hollow flow channel 211, that is, by setting the first conveying pipe 31, the second conveying pipe 32 and the third conveying pipe 33 through the hollow flow channel 211, not only can the consumables conveyed through the first conveying pipe 31 be prevented from contacting the inner wall of the hollow flow channel 211, but also the consumables conveyed through the second conveying pipe 32 can be prevented from contacting the inner wall of the hollow flow channel 211, and the consumables conveyed through the third conveying pipe 33 can be prevented from contacting the inner wall of the hollow flow channel 211, thereby reducing the pollution effect of the consumables on the hollow flow channel 211 during the process of conveying through the hollow flow channel 211.

[0092] Among them, the first delivery tube 31, the second delivery tube 32 and the third delivery tube 33 can transport the same consumables, or they can all transport different consumables. It is also possible that two of the delivery tubes transport the same consumables and the other delivery tube transports different consumables. Users can set the type of consumables for each delivery tube based on actual needs to meet the user's care needs.

[0093] In some embodiments, the third delivery pipe 33 further includes a sixth delivery pipe segment, which is a delivery pipe segment of the third delivery pipe 33 used to connect the third consumable material outlet of the drive pump 10 and the third delivery pipe segment 331 .

[0094] In some embodiments, a fourth delivery tube, a fifth delivery tube, etc. can also be provided in the consumables delivery assembly to meet the user's care needs in different scenarios.

[0095] It should be noted that the number of delivery tubes in the consumables delivery assembly can be one, two, three or more, and is not specifically limited here.

[0096] Any two of the first conveying pipe section 311 , the second conveying pipe section 321 and the third conveying pipe section 331 can be distributed in the hollow flow channel 211 in any manner of parallel, winding or sleeved, and form a flow channel for conveying consumables.

[0097] In some embodiments, as Figure 10 As shown, the first conveying pipe section 311 , the second conveying pipe section 321 and the third conveying pipe section 331 are sub-flow channels distributed in parallel within the hollow flow channel 211 .

[0098] In some embodiments, at least two of the first conveying pipe segment 311, the second conveying pipe segment 321, and the third conveying pipe segment 331 can be distributed in the hollow flow channel 211 and entangled with each other, and form sub-flow channels that are entangled with each other and arranged side by side in the hollow flow channel 211, so as to respectively convey the consumables conveyed through the first conveying pipe 31, the consumables conveyed through the second conveying pipe 32, and / or the consumables conveyed through the third conveying pipe 33.

[0099] For example, the first conveying pipe section 311 and the second conveying pipe section 321 can be distributed in the hollow flow channel 211 in a mutually entangled manner, and the third conveying pipe section 331 and the first conveying pipe section 311 are distributed in parallel in the sub-flow channel in the hollow flow channel 211, or the third conveying pipe section 331 and the second conveying pipe section 321 are distributed in parallel in the sub-flow channel in the hollow flow channel 211.

[0100] For another example, the first conveying pipe segment 311, the second conveying pipe segment 321, and the third conveying pipe segment 331 are all intertwined and distributed within the hollow flow channel 211, so as to form three intertwined sub-flow channels within the hollow flow channel 211. For another example, the first conveying pipe segment 311 and the second conveying pipe segment 321 are intertwined, and the third conveying pipe segment 331 is sleeved over the first conveying pipe segment 311 and the second conveying pipe segment 321. The inner tube of the first conveying pipe segment 311 and the inner tube of the second conveying pipe segment 321 form two independent flow channels for conveying consumables, and a gap flow channel for conveying consumables is formed between the inner tube wall of the third conveying pipe segment 331 and the outer tube walls of the first conveying pipe segment 311 and the outer tube walls of the second conveying pipe segment 321.

[0101] In some embodiments, as Figure 11 As shown, the first delivery pipe section 311 is sleeved on the second delivery pipe section 321, and the second delivery pipe section 321 is sleeved on the third delivery pipe section 331;

[0102] Among them, a second gap flow channel 42 is formed between the inner tube wall of the first conveying pipe section 311 and the outer tube wall of the second conveying pipe section 321, and the second gap flow channel 42 is used to convey the consumables conveyed through the first conveying pipe 31; a third gap flow channel 43 is formed between the inner tube wall of the second conveying pipe section 321 and the outer tube wall of the third conveying pipe section 331, and the third gap flow channel 43 is used to convey the consumables conveyed through the second conveying pipe 32.

[0103] In some embodiments, as Figure 12 As shown, the first conveying pipe section 311 is sleeved on the second conveying pipe section 321 and the third conveying pipe section 331, and the second conveying pipe section 321 and the third conveying pipe section 331 are sub-flow channels distributed in parallel within the first conveying pipe section 311;

[0104] A fourth gap flow channel 44 is formed between the inner tube wall of the first conveying pipe section 311 and the outer tube walls of the second conveying pipe section 321 and the outer tube walls of the third conveying pipe section 331 . The fourth gap flow channel 44 is used to convey the consumables conveyed through the first conveying pipe 31 .

[0105] In some embodiments, as Figure 13 As shown, the first conveying pipe section 311 is sleeved on the second conveying pipe section 321, and the first conveying pipe section 311 and the third conveying pipe section 331 are sub-channels distributed in parallel in the hollow channel 211;

[0106] A fifth gap flow channel 45 is formed between the inner tube wall of the first conveying pipe section 311 and the outer tube wall of the second conveying pipe section 321 . The fifth gap flow channel 45 is used to convey the consumables conveyed through the first conveying pipe 31 .

[0107] In some embodiments, the first delivery tube 31 , the second delivery tube 32 and the third delivery tube 33 may be made of soft materials such as soft glue, silicone, rubber, etc., or may be made of hard materials such as plastic, metal, alloy, etc., which are not limited here.

[0108] Specifically, the delivery tube in the consumable material delivery assembly can be made of soft material, hard material, or partially made of soft material and partially made of hard material. In addition, the delivery tube in the consumable material delivery assembly can be integrally formed or split.

[0109] For example, the first conveying tube 31 of the consumable material conveying assembly can be a conveying tube made of soft material, and the second conveying tube 32 of the consumable material conveying assembly can be a conveying tube made of hard material; or, the first conveying tube 31 and the second conveying tube 32 of the consumable material conveying assembly are both conveying tubes made of soft material, or, the first conveying tube 31 and the second conveying tube 32 of the consumable material conveying assembly are both conveying tubes made of hard material.

[0110] In some embodiments, the delivery tube in the consumables delivery assembly can adopt the above-mentioned hollow flow channel 211 in a bent or unbent manner; for example, the delivery tube can be a straight tube or a spiral tube, and correspondingly, the flow channel formed is a straight channel or a spiral flow channel.
