[0074] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0075] The terms “first”, “second”, and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by “first”, “second”, etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, “and / or” in the specification and claims indicates at least one of the connected objects, and the character “ / ” generally indicates that the front and rear associated objects are in an “or” relationship.

[0076] The core, the care head, the motor, the consumable dispensing module, the personal care device, and the control method of the personal care device provided in the embodiments of the present application will be described in detail below with reference to the drawings, specific embodiments, and application scenarios.

[0077] The personal care device of the embodiments of the present application can be, for example, an electric toothbrush, a skin care instrument, a face washing instrument, or the like, and the consumable can be toothpaste, skin care products, cleaning agents, or the like. For ease of understanding and description, the embodiments of the present application will be specifically described taking an electric toothbrush as an example.

[0078] As shown in FIGS. 1-2, the personal care device includes a consumable container 1, a core 2, a care unit 3, and a plurality of independent consumable flow channels communicating the consumable container 1, the core 2, and the care unit 3. The cross-sectional shape of each consumable flow channel can be one or a combination of a circle, an ellipse, a polygon, and an irregular shape. Moreover, each consumable flow channel can be a straight pipe, a curved pipe, a spiral pipe, or an irregular pipe, which is not limited in the present application.

[0079] The core 2 will be described below. As shown in FIGS. 3-4, the core 2 includes:

[0080] The first power device 21 is used to provide power for the consumable container 1 of the personal care device, and the first power device 21 has at least two driving states; the second power device 22 is used to provide power for the care unit 3 of the personal care device; wherein the first power device 21 and the second power device 22 are respectively provided with at least two independent channels, and the corresponding channels of the first power device 21 and the second power device 22 are sequentially connected to form at least two independent consumable flow channels.

[0081] Optionally, the movement core 2 can further include a first connecting seat 23 connected with the first power device 21 and the second power device 22. In this embodiment, the first connecting seat 23 is provided with at least two independent channels, and the corresponding channels of the first power device 21, the first connecting seat 23 and the second power device 22 are sequentially connected to form at least two independent consumable flow channels.

[0082] It should be understood that the first power device 21 and the second power device 22 can be directly connected or connected through the first connecting seat 23.

[0083] The personal care device of the embodiment of the present application can realize independent transmission of multiple consumables by using the channels or grooves provided by the internal components (such as the first power device 21, the first connecting seat 23 and the second power device 22), and form an overall independent consumable flow channel through multiple segmented channels or grooves, thereby avoiding mixing and pollution of different consumables.

[0084] In order to facilitate explanation and understanding, two independent consumable flow channels are taken as an example for description in the embodiment of the present application, the first consumable flow channel is used to transmit the first consumable, and the second consumable flow channel is used to transmit the second consumable. Since the two consumable flow channels are independently transmitted, the problem of consumable mixing does not occur, and the problem of mixing and mutual pollution during multiple consumable transmission can be fundamentally solved.

[0085] The flow path of the consumable in the movement core 2 is: the first power device 21→the first connecting seat 23→the second power device 22. The specific structure of each part of the movement core 2 of the present application will be described in the following according to the flow path of the consumable:

[0086] The first power device 21 is used to provide transmission power for the whole process of outputting the consumable from the consumable container 1 to the care unit 3. In the embodiment of the present application, one first power device 21 can be used to control the output of the consumables of the two consumable flow channels, or two independent first power devices 21 can be used to control the output of the consumables of the two consumable flow channels.

[0087] Optionally, one first power device 21 is used to control the output of the consumables of the two consumable flow channels, which is beneficial to saving the installation space of the first power device 21 and facilitating the miniaturization design of the whole machine.

[0088] The first power device 21 can have a single or multiple driving states, that is, the consumables of different consumable flow channels can be output simultaneously or individually, and the application does not limit the output order and output time of the consumables.

[0089] Optionally, the first power device 21 includes at least two driving states, and the at least two driving states are used to respectively control the output of the consumables in the at least two independent consumable flow channels.

[0090] The first power device 21 is a driving device with at least two driving states, for example, a rotary pump. The rotary pump includes any one of a peristaltic pump, a gear pump, a screw pump, a rotor pump, and a plunger pump.

[0091] Taking two independent consumable flow channels as an example, the first power device 21 has two driving states. Then, the output of the consumables in the two independent consumable flow channels can be respectively controlled by switching (such as forward rotation and reverse rotation) of the two driving states of the first power device 21. For example, when the first power device 21 rotates forward, the first consumable flow channel is in a conductive state, the second consumable flow channel is in a non-conductive state, the first consumable is output from the first consumable flow channel, and the second consumable is not output; and when the first power device 21 rotates reversely, the second consumable flow channel is in a conductive state, the first consumable flow channel is in a non-conductive state, the second consumable is output from the second consumable flow channel, and the first consumable is not output.

[0092] It can be understood that the first power device 21 can also control the consumables in the two consumable flow channels to be output simultaneously when rotating forward or reversely, and the specific setting can be made according to the corresponding nursing mode of the consumables, and the application does not limit this.

[0093] Taking three consumable flow channels as an example, the first power device 21 can control the output of the consumables in the three consumable flow channels simultaneously, or can control the output of the consumables in one consumable flow channel and two consumable flow channels respectively by forward rotation and reverse rotation of one first power device 21. For example, the output of the consumables in the first consumable flow channel is controlled when rotating forward, and the output of the consumables in the second consumable flow channel and the third consumable flow channel is controlled simultaneously when rotating reversely. For another example, the first consumable flow channel is controlled when rotating reversely, and the second consumable flow channel and the third consumable flow channel are controlled when rotating forward, and so on. In the case of four, five or more consumable flow channels, the number and type of the consumable flow channels corresponding to the different driving states of the first power device 21 can be set according to actual needs, and the application does not limit this. That is, the application does not limit the number, type, and output order of the consumables in the multiple consumable flow channels, and there can be many variations and combinations, which can be set according to the actual nursing needs and the reasonable collocation of the types of consumables, and the application does not limit this.

[0094] It should be noted that the consumables are output from independent flow channels, and thus cannot be mixed. Here, only the different driving states of the first power device 21 are used to switch and control the output of the consumables in different consumable flow channels.

[0095] Two specific embodiments (i.e., Embodiment One and Embodiment Two) are provided below to exemplarily illustrate the first power device 21 of the embodiments of the present application.

[0096] Embodiment One

[0097] As shown in FIGS. 4-5, the first power device 21 includes a driving pump 211 and at least two one-way valves 212. The driving pump 211 includes at least two driving states, and is provided with at least two inlet interfaces 217 and at least two outlet interfaces. The at least two one-way valves 212 are respectively arranged at the at least two inlet interfaces 217 or the at least two outlet interfaces, or are respectively arranged at corresponding consumable flow channels. In different driving states of the driving pump 211, at least part of the at least two consumable flow channels are in a conductive state.

[0098] FIG. 6 shows a structural schematic diagram of the one-way valve 212. The one-way valve 212 is arranged to ensure that the consumables can be delivered in only one direction. The one-way valve 212 can be arranged at the inlet interface 217 of the driving pump 211, or can be arranged at the outlet interface of the driving pump 211. If the one-way valve 212 is arranged at the inlet interface 217 of the driving pump 211, the one-way valve 212 constitutes the inlet end of the driving pump 211. By arranging the one-way valve 212, different consumables can be output by the first power device 21 in different driving states to meet the needs of users.

[0099] Optionally, the driving pump 211 is a peristaltic pump, which includes a driving motor 213, a first pump head 215a and a second pump head 215b connected to the rotating shaft of the driving motor 213 respectively, and a first hose 216a and a second hose 216b. The first hose 216a is arranged around the first pump head 215a, and the second hose 216b is arranged around the second pump head 215b. The in-out winding directions of the first hose 216a and the second hose 216b are opposite.

[0100] The forward rotation and the reverse rotation of the driving motor 213 correspond to the first driving state and the second driving state respectively. When the driving motor 213 rotates in the first direction or the second direction, at least part of the at least two independent consumable flow channels are in a conductive state.

[0101] In this embodiment, the two hoses are arranged to be led out from the two sides of the peristaltic pump and can be connected to the input interfaces of the first connecting seat 23 respectively. In this way, the internal space of the machine body can be reasonably utilized, the components can be compactly arranged and connected, the overall size of the machine can be avoided to be increased, and the miniaturization of the machine can be facilitated.

[0102] In this embodiment, at least two consumable transmissions are achieved by using the forward and reverse rotation of the peristaltic pump and the one-way transmission of the one-way valve 212, and the working principle is as follows:

[0103] For example, at least two one-way valves 212 include a first one-way valve 212a and a second one-way valve 212b, and the two one-way valves 212 allow the consumable to be input to the hose of the peristaltic pump in only one direction, and at the same time, the two hoses are arranged around the corresponding pump head of the peristaltic pump; but the in-out winding directions of the two hoses are opposite, the in-out winding direction of one hose is clockwise, and the in-out winding direction of the other hose is counterclockwise. Thus, when the peristaltic pump rotates forward (clockwise), the first pump head 215a will squeeze the first hose 216a, so that the first consumable in the first chamber of the consumable container 1 flows through the first hose 216a, the first connecting seat 23, the second power device 22, and finally is output through the nursing unit 3. And because the second one-way valve 212b is in the opposite direction of the peristaltic pump at this time, the consumable flow passage where the second one-way valve 212b is located is in a non-conductive state, so the second consumable in the second chamber of the consumable container 1 will not be transmitted. When the peristaltic pump rotates reversely (counterclockwise), the second consumable is output, and the first consumable is not output.

[0104] Optionally, the first one-way valve 212a and the second one-way valve 212b are respectively arranged at any position of the following: the feeding interface 217 or the discharging interface of the driving pump 211; the outlet end, the inlet end, or between the inlet end and the outlet end of the first hose 216a or the second hose 216b.

[0105] Specifically, the first one-way valve 212a is arranged at the feeding interface 217 of the driving pump 211, or the first one-way valve 212a is arranged at the discharging interface of the driving pump 211, or the first one-way valve 212a is arranged at the inlet end of the first hose 216a, or the first one-way valve 212a is arranged at the outlet end of the first hose 216a, or the first one-way valve 212a is arranged between the inlet end and the outlet end of the first hose 216a;

[0106] The second one-way valve 212b is arranged at the feeding interface 217 of the driving pump 211, or the second one-way valve 212b is arranged at the discharging interface of the driving pump 211, or the second one-way valve 212b is arranged at the inlet end of the second hose 216b, or the second one-way valve 212b is arranged at the outlet end of the second hose 216b, or the second one-way valve 212b is arranged between the inlet end and the outlet end of the second hose 216b.

[0107] In this embodiment, the one-way valve 212 can be arranged at the inlet interface of the peristaltic pump, at the outlet interface of the peristaltic pump, at the inlet end of the hose, at the outlet end of the hose, or at the input interface of the first connecting seat 23. In other words, the one-way valve 212 can be arranged at any position of the first connecting seat 23 to the consumable container 1. Preferably, the one-way valve 212 is arranged at the inlet interface of the peristaltic pump, so that the consumable enters the consumable flow channel only when it needs to be output.

[0108] Optionally, the core 2 further comprises at least two consumable input pipelines 24, the consumable input pipelines 24 and the corresponding hoses are connected through the inlet interface 217, wherein the at least two one-way valves are arranged at the corresponding consumable input pipelines 24 respectively, and the directions of the at least two one-way valves are consistent with the input direction of the consumable.

[0109] Optionally, the hose of the driving pump 211 can be directly connected with the first connecting seat 23, or the core 2 further comprises at least two connecting members 25, the first connecting seat 23 and the corresponding hose are connected through the connecting members 25.

[0110] Optionally, the driving pump 211 further comprises a pump head shell and a pump head cover, the first pump head 215a and the second pump head 215b are arranged in the space enclosed by the pump head shell and the pump head cover, and the first hose 216a and the second hose 216b are arranged in the space enclosed by the pump head shell and the pump head.

[0111] Optionally, the driving pump 211 further comprises a speed reduction motor 214 arranged between the driving motor 213 and the pump head. The speed reduction motor 214 can adopt a gear or planetary gear structure.

[0112] It can be understood that the embodiment of the present application further provides a consumable dispensing module, which comprises at least two consumable transmission pipelines (i.e. the two independent consumable flow channels) and a driving pump. The one-way conduction element is arranged on each consumable transmission pipeline. The driving pump comprises at least two driving states, which are used to provide transmission power for the at least two consumable transmission pipelines; wherein the driving pump is in the first driving state or the second driving state, and at least part of the at least two consumable transmission pipelines is in the conduction state.

[0113] Optionally, the one-way conduction state of the one-way conduction element on the consumable transmission pipeline of the first part corresponds to the first driving state of the driving pump, and the one-way conduction state of the one-way conduction element on the consumable transmission pipeline of the second part corresponds to the second driving state of the driving pump; when the driving pump is in the first driving state, the consumable transmission pipeline of the first part is in the conduction state, and the consumable transmission pipeline of the second part is in the non-conduction state; when the driving pump is in the second driving state, the consumable transmission pipeline of the first part is in the non-conduction state, and the consumable transmission pipeline of the second part is in the conduction state; wherein the consumable connected by the consumable transmission pipeline in the conduction state can be output, and the consumable connected by the consumable transmission pipeline in the non-conduction state cannot be output. By using the consumable supply module in this embodiment, the driving pump includes multiple driving states, and by switching between different driving states, the output of consumables in different consumable transmission pipelines can be controlled. In addition, by using the one-way conduction element arranged on the consumable transmission pipeline, the one-way conduction on the corresponding consumable transmission pipeline is set to ensure that the consumable in the consumable transmission pipeline in the conduction state can be output through the one-way conduction element. In this way, the driving pump cooperates with the one-way conduction element to control the output of consumables in different consumable transmission pipelines, so as to realize the supply function of the consumable supply module, without the need to set multiple transmission pumps and realize the control output of multiple consumables by pipeline switching.

[0114] Optionally, each consumable transmission pipeline can include a pipeline part made of one or more materials such as soft rubber, rubber, plastic, metal, alloy, etc. The driving pump is a transmission pump with multiple driving states, which can include one or more of a peristaltic pump, a gear pump, a screw pump, a rotor pump, and a plunger pump. Preferably, the driving pump is a peristaltic pump, which includes two driving states of forward rotation and reverse rotation.

[0115] In this embodiment, the consumable supply module in the embodiment of the application takes a double-pump-head peristaltic pump as an example, as shown in FIG. 5 and FIG. 7, the driving pump 211 includes a driving motor 213, at least two pump heads connected to the rotating shaft of the driving motor 213, and at least two transmission hoses respectively arranged in the at least two pump heads; wherein the driving pump 211 is connected to the corresponding consumable transmission pipeline through the transmission hose, and each pump head is used to provide consumable conveying power for the corresponding consumable transmission pipeline in the conduction state when the driving motor 213 executes the corresponding driving state.

[0116] In the drive pump, each pump head comprises a containing space, which is a space enclosed by the pump head shell and the pump head cover, and the containing space is provided with the extrusion component 218; wherein the corresponding transmission hose is arranged around the extrusion component 218 in the containing space; wherein in the first driving state, the drive motor 213 drives the extrusion component 218 on the first pump head 215a in the pump head to rotate in the clockwise direction; in the second driving state, the drive motor 213 drives the extrusion component 218 on the second pump head 215b in the pump head to rotate in the counterclockwise direction.

[0117] That is, in this embodiment, the at least two consumable transmission pipelines are independent consumable flow channels, the two transmission hoses are the first hose 216a and the second hose 216b respectively, the two one-way conduction elements are the first one-way valve 212a and the second one-way valve 212b respectively, and the drive pump is the drive pump 211, and the two pump heads comprise the first pump head 215a and the second pump head 215b.

[0118] The transmission hose (the first hose 216a) of the first pump head 215a is in communication with the first part of the at least two consumable transmission pipelines, the transmission hose (the second hose 216b) of the second pump head 215b is in communication with the second part of the at least two consumable transmission pipelines, and the winding directions of the transmission hose (the first hose 216a) of the first pump head 215a and the transmission hose (the second hose 216b) of the second pump head 215b are opposite.

[0119] Optionally, the consumable distribution module can further comprise a control element electrically connected to the drive pump, and the control element is used to control the rotation direction of the drive motor.

[0120] In the first driving state of the drive pump, the drive motor drives the extrusion component 218 on the first pump head 215a and the extrusion component 218 on the second pump head 215b to rotate in the clockwise direction, the transmission directions of the consumables in the transmission hose of the first pump head 215a and the transmission hose of the second pump head 215b are clockwise, which is the same as the conduction direction of the one-way conduction element on the first consumable transmission pipeline, but opposite to the conduction direction of the one-way conduction element on the second consumable transmission pipeline, so that the first consumable transmission pipeline is in the conduction state, and the second consumable transmission pipeline is in the non-conduction state.

[0121] In the second driving state, the driving motor drives the extrusion components on the first pump head 215a and the second pump head 215b to rotate in the counterclockwise direction, and the transmission direction of the consumables in the transmission hose of the first pump head 215a and the transmission hose of the second pump head 215b is counterclockwise, which is the same as the conduction direction of the one-way conduction element on the second consumable transmission pipeline but opposite to the conduction direction of the one-way conduction element on the first consumable transmission pipeline, so that the second consumable transmission pipeline is in the conduction state and the first consumable transmission pipeline is in the non-conduction state. In an embodiment, the one-way conduction element on the first consumable transmission pipeline is arranged at the consumable input end of the first consumable transmission pipeline, and the one-way conduction element on the second consumable transmission pipeline is arranged at the consumable input end of the second consumable transmission pipeline. It should be noted that the one-way conduction element is not limited to being arranged at the consumable input end of the consumable transmission pipeline, but can also be arranged at the consumable output end of the corresponding consumable transmission pipeline or at the middle position of the corresponding consumable transmission pipeline.

[0122] Optionally, the one-way conduction element can be made of soft rubber material, such as silicone or rubber. Optionally, the one-way conduction element adopts a one-way valve structure, such as a duckbill valve, as shown in the structure of the one-way valve 212 in FIG. 8. Taking the structure of the one-way valve 212 in FIG. 6 as an example, the one-way conduction element includes a valve seat 2121 and a valve body 2122 extending from the valve seat 2121, and the valve body 2122 is formed as a flat body structure with a cut. When the one-way conduction element is installed on the consumable transmission pipeline, the direction from the valve seat 2121 to the valve body 2122 is the conduction direction of the one-way conduction element. Since the valve body 2122 is formed as a flat body structure with a cut and is made of soft material, it can play a role in forward conduction transmission and reverse cut-off when transmitting consumables.

[0123] In an embodiment, the extrusion component includes a plurality of protruding rotating shafts. During the rotation of the first pump head 215a and the second pump head 215b around the central axis, the plurality of rotating shafts rotate, and each rotating shaft rotates around its own axis, which can extrude the consumable transmission pipeline.

[0124] With this implementation structure, the corresponding relationship between the one-way conduction element and the driving state of the peristaltic pump can be used to set the output of the target consumable transmission pipeline in the corresponding driving state, so that different types of consumables can be output respectively in the case that different consumable transmission pipelines are connected to different consumable supply bottles or consumable chambers.

[0125] Based on the above principle, optionally, the driving pump can be provided with more than two pump heads, each of which is connected to a different consumable transmission pipeline for driving the consumable in the pipeline to be output. With this embodiment, in one driving state of the driving pump, the consumable in at least two consumable transmission pipelines can be controlled to be output. For example, when the transmission hoses connected in the two pump heads are wound in the same counterclockwise direction in the accommodation space of the pump head, the rotation of the driving pump in one direction can control the output of the consumables in the two consumable transmission pipelines. When the two consumable transmission pipelines are connected to the same consumable bottle or the same consumable accommodation cavity, one kind of consumable can be output at the same time; and when the two consumable transmission pipelines are connected to different consumable bottles or different consumable accommodation cavities, different consumables can be output at the same time.

[0126] Therefore, based on the above principle, when the driving pump is in the first driving state, the first part of the consumable transmission pipeline is in a conductive state, and when the driving pump is in the second driving state, the second part of the consumable transmission pipeline is in a conductive state. The number of consumable transmission pipelines in the first part and the second part can be greater than or equal to 1. Optionally, when the number of consumable transmission pipelines in the first part is greater than or equal to 2, the number of consumable transmission pipelines in the second part can also be 0.

[0127] Optionally, as shown in FIG. 6, the driving pump 211 further comprises a feeding interface 217 for connecting the consumable input pipeline 24 and the transmission hose. The feeding interface 217 comprises a main body 2171 and a third interface 2172 and a fourth interface 2173 arranged on the main body 2171. The third interface 2172 and the fourth interface 2173 are respectively used to connect the consumable input pipeline 24 and the transmission hose.

[0128] With this embodiment structure, the feeding interface 217 is arranged between the consumable input pipeline 24 and the transmission hose, so as to facilitate the assembly and connection between the consumable input pipeline 24 and the transmission hose.

[0129] It is worth mentioning that the third interface 2172 and the fourth interface 2173 of the feeding interface 217 are arranged in two perpendicular directions of the main body 2171, so that the third interface 2172 is used for inputting the consumable, and the fourth interface 2173 is used for changing the output direction of the consumable, facilitating the flow of the consumable from the consumable input pipeline 24 to the transmission hose.

[0130] Optionally, the third interface 2172 and the fourth interface 2173 are further respectively provided with anti-dropping structures, so as to enhance the stability of the connection between the consumable input pipeline 24 and the transmission hose, avoid the falling of the two, and also ensure the sealing of the consumable flow path to avoid leakage during the transmission of the consumable.

[0131] Optionally, in the embodiment of the present application, one consumable supply bottle can be connected to one consumable transmission pipeline, and multiple consumable transmission pipelines can output the same or different consumables.

[0132] Optionally, in the embodiment of the present application, one consumable supply bottle can be connected to one consumable transmission pipeline, and multiple consumable transmission pipelines can output different consumables independently to avoid the problem of odor mixing and mixing of different consumables during output.

[0133] In the embodiment of the present application, the driving pump is taken as an example of a peristaltic pump, and the specific implementation structure of the consumable dispensing module is described. However, it should be noted that the driving pump is not limited to a peristaltic pump, but can also be any one of a gear pump, a screw pump, a rotor pump, and a plunger pump. The specific implementation structure and principle of any one of the gear pump, the screw pump, the rotor pump, and the plunger pump can be referred to the implementation modes described above, and each implementation mode will not be described separately.

[0134] In addition, the number of consumable transmission pipelines is not limited to two, and the specific number is not limited. The correspondence between the conduction state of the consumable transmission pipeline and the driving state of the driving pump can be adjusted according to actual needs. Specifically, the position and conduction direction of the one-way conduction element can be adjusted.

[0135] In the embodiment of the present application, the cross-sectional shape of the consumable transmission pipeline can be one or a combination of a circle, an ellipse, a polygon, and an irregular shape. Moreover, the consumable transmission pipeline can be a straight pipe, a curved pipe, a spiral pipe, or an irregular pipe, and the present application does not limit this.

[0136] Optionally, the consumable transmission pipeline of the present application can also include a transition pipeline connecting the output ports of multiple consumable transmission pipelines and a consumable output end. The consumable output end can be a brush head, a massage head, a cleaning head, an application head, a hair treatment head, or other care head structures. The transition pipeline can be multiple independent pipelines or a common pipeline, and the present application does not limit this.

[0137] The consumable dispensing module of the embodiment of the present application can provide consumable conveying power to the consumable flow path in the conduction state (target consumable flow path) by controlling the driving pump to switch different driving states. With this implementation structure, complex consumable flow path switching mechanisms are not required, and the output switching of multiple consumables can be achieved. The implementation mode of the multiple consumable transmission is simple and easy to implement. Moreover, the one-way conduction element and the driving pump do not occupy much installation space, which is conducive to the miniaturization of the whole personal care device.

[0138] Embodiment Two

[0139] In this embodiment, the first power device is a transmission pump. As shown in FIGS. 9-15, the transmission pump includes a first pump head 51, a second pump head 52, a driving device 53, and a pump head switching mechanism for driving the driving device 53, the first pump head 51, and the second pump head 52. The pump head switching mechanism is configured to control the first pump head 51 to work when the driving device 53 rotates in a first direction and to control the second pump head 52 to work when the driving device rotates in a second direction. The first direction is opposite to the second direction. Optionally, the rotation of the driving device 53 in the first direction is referred to as forward rotation, and the rotation of the driving device 53 in the second direction is referred to as reverse rotation.

[0140] In this embodiment, the pump head switching mechanism is configured to control the first pump head 51 and the second pump head 52 to work when the driving device 53 rotates forward and reversely, respectively. In this way, the control switching of the first pump head and the second pump head can be realized only by the forward rotation and reverse rotation of the driving device, and the transmission control of different consumables can be realized by simple control instructions.

[0141] Optionally, the transmission pump further includes a pump head shell 54 and a pump head cover 55. As shown in FIGS. 9 and 10, the pump head shell 54 and the pump head cover 55 form a containing space, and the first pump head 51 and the second pump head 52 are located in the containing space. The pump head shell 54 and the pump head cover 55 constitute a protective shell for protecting the internal pump heads and avoiding the influence of the external environment on the pump heads.

[0142] As shown in FIG. 10, the first pump head 51, the second pump head 52, and the driving device 53 are arranged in a linear sequence. Optionally, the driving device 53 includes a driving shaft 531, and the pump head switching mechanism includes a first one-way driving component 511 and a second one-way driving component 521 which are respectively sleeved on the driving shaft 531. The driving shaft 531 drives the first pump head 51 to rotate in the first direction through the first one-way driving component 511, and drives the second pump head 52 to rotate in the second direction through the second one-way driving component 521.

[0143] The one-way driving component is configured to realize the driving function in one direction. As shown in FIGS. 10 and 11, the driving device 53 is provided with a driving shaft 531 which extends into the containing space and is drivingly connected with the first one-way driving component 511 and the second one-way driving component 521, respectively. The driving connection refers to the driving function between the two components through the connection to realize the transmission of driving force. In this embodiment, the driving connection enables the driving force of the driving shaft 531 to be transmitted to the first one-way driving component 511 and the second one-way driving component 521, so as to drive the first one-way driving component 511 and the second one-way driving component 521 to move.

[0144] When the driving device 53 controls the driving shaft 531 to rotate in the first direction, the driving shaft 531 drives the first pump head 51 to rotate in the first direction through the first one-way driving component 511, and the second pump head 52 remains in a non-working state; when the driving device 53 controls the driving shaft 531 to rotate in the second direction, the driving shaft 531 drives the second pump head 52 to rotate in the second direction through the second one-way driving component 521, and the first pump head 51 remains in a non-working state; wherein the first direction is opposite to the second direction, and in this embodiment, the first direction is the forward rotation direction of the driving shaft 531 of the driving device 53, and the second direction is the reverse rotation direction of the driving shaft 531 of the driving device 53.

[0145] In this embodiment, the driving directions of the first one-way driving component 511 and the second one-way driving component 521 are opposite, so that when the driving shaft 531 rotates in the first direction, the driving function of the first one-way driving component 511 is effective, and the first pump head 51 can be driven to rotate in the first direction, while the driving function of the second one-way driving component 521 is not effective, so the second pump head 52 remains in a non-working state; similarly, when the driving shaft 531 rotates in the second direction, the driving function of the second one-way driving component 521 is effective, and the second pump head 52 can be driven to rotate in the second direction, while the driving function of the first one-way driving component 511 is not effective, so the first pump head 51 remains in a non-working state.

[0146] In this way, on the one hand, the two kinds of pump heads can meet the transmission needs of various consumables and can avoid pollution between different consumables, and on the other hand, the control switching of the first pump head and the second pump head can be realized by forward rotation and reverse rotation of the driving shaft, and the transmission control of different consumables can be realized by simple control instructions.

[0147] The driving device 53 can be a driving motor.

[0148] It should be noted that the first pump head 51 and the second pump head 52 refer to two kinds of pump heads arranged in the transmission pump, and the first pump head 51 and the second pump head 52 are respectively used for transmitting different categories of consumables, and when the driving motor rotates forward, the first pump head 51 works and the second pump head 52 does not work, and when the driving motor rotates reversely, the first pump head 51 does not work and the second pump head 52 works, so that the control of different consumables transmission can be realized only by controlling the forward and reverse rotation of the driving motor.

[0149] It can be understood that the specific number of the first pump head and the second pump head is not limited in this application, and the scene of arranging one first pump head and one second pump head is shown in the drawings, and in actual application, a plurality of first pump heads and a plurality of second pump heads can be arranged according to needs.

[0151] Further, the consumables transported in the above pump head a and pump head c can also be of different types, for example, pump head a is used to transport consumable A, pump head c is used to transport consumable B, and pump head b and pump head d are used to transport consumable C, when consumable A and B need to be transported, the driving motor is controlled to rotate forward, pump head a and pump head c work, and pump head b and pump head d do not work, so as to realize the transportation of consumable A and B, when consumable C needs to be transported, the driving motor is controlled to rotate reversely, pump head b and pump head d work, and pump head a and pump head c do not work, so as to realize the transportation of consumable C.

The elastic member is fixed at one end on the cylinder body and at the other end on the end of the pump head where no ratchet gear is arranged. The elastic member generates a supporting force on the cylinder body, so as to ensure that the cylinder body can be pressed on the end of the pump head where the ratchet gear is arranged, and to ensure that the ratchet gears on the cylinder body and the pump head can cooperate with each other.

[0175] Referring to FIGS. 9 and 10, optionally, the transmission pump further includes a first hose 57, a second hose 58, a first interface group 59, and a second interface group 510; the first hose 57 is located between the first pump head 51 and the pump head shell 54 and is arranged around the first pump head 51, the first interface group 59 is arranged on the pump head shell 54 and is in communication with both ends of the first hose 57, respectively; the second hose 58 is located between the second pump head 52 and the pump head shell 54 and is arranged around the second pump head 52, and the second interface group 510 is arranged on the pump head shell 54 and is in communication with both ends of the second hose 58, respectively.

[0176] Optionally, the first pump head 51 includes a first pump head body 5101 connected with the pump head switching mechanism and a plurality of first pressing parts 5102 arranged on the first pump head body 5101; the first pressing part 5102 is a roller pivotally connected with the outer side surface of the first pump head body 5101, or the first pressing part 5102 is a protruding structure integrally formed with the outer side surface of the first pump head body 5101.

[0179] In the embodiments of the present application, the transmission pump is specifically designed as a peristaltic pump. The working principle is that the pump head rotates to drive the extrusion parts on the outer periphery of the pump head to rotate. The extrusion parts cooperate with the pump head shell to extrude the hose. Since a plurality of extrusion parts are arranged on the outer periphery of the pump head, the hose is alternately extruded, and a pressure is formed in the tube. The pressure serves as the transmission power of the consumable in the tube, thereby realizing the transmission of the consumable in the hose.

[0180] It should be noted that the scene in which three extrusion parts are arranged on the outer periphery of the pump head is shown in the drawings. It can be understood that the number of extrusion parts arranged on the outer periphery of the pump head is not limited in the embodiments of the present application, and can be flexibly arranged according to actual needs. Optionally, the plurality of extrusion parts are uniformly distributed on the outer periphery of the pump head to ensure the stability of the consumable transmission rate.

[0183] In the embodiments of the present application, the extrusion part can specifically adopt a roller structure to reduce the frictional resistance with the hose, or the extrusion part can specifically adopt a protruding structure integrally formed with the pump head. The integrally formed design simplifies the overall structure, reduces the overall volume of the pump head, and can also avoid the risk of pump head jamming caused by the falling of the roller.

[0231] The above is the relevant description of the first connecting seat. The following describes the relevant embodiments of the second power device.

[0232] As shown in FIG. 23 to FIG. 26, the second power device 22 is a motor 221 with a multi-channel hollow rotating shaft 222, which includes: a multi-channel hollow rotating shaft 222; a rotor group 223 mounted on the multi-channel hollow rotating shaft 222; and a stator group 224 arranged at intervals on the rotor group 223.

The hollow rotating shaft 222 passes out of the housing at both ends. The motor 221 further includes two bearings arranged at both ends of the multi-channel hollow rotating shaft 222, respectively.

[0235] The hollow rotating shaft 222 is provided with a plurality of independent third channels 227, so the hollow rotating shaft 222 can be called a multi-channel hollow rotating shaft. In this specific embodiment, the hollow rotating shaft 222 can be provided with two independent third channels 227, and the hollow rotating shaft 222 has a rotating shaft body and a partition connected to the rotating shaft body, and the partition separates the rotating shaft body to form two independent third channels 227.

[0236] The hollow rotating shaft 222 can be a round tube or a flat tube. In particular, the end of the hollow rotating shaft 222 connected to the rotor set 223 is provided in a flat tube shape, which can ensure that the hollow rotating shaft 222 has sufficient space to arrange multiple channels, while reducing the installation space occupied by the rotor support, thereby facilitating the rotor support to reserve more space for winding, thereby increasing the number of coil turns, so as to improve the performance of the motor 221 (such as increasing the swing and torque of the motor 221) without increasing the volume of the motor 221. Correspondingly, the slot 232 of the first connecting seat 23 is also flat tube-shaped, that is, the shapes and structures of the two are matched.

[0237] The motor with a multi-channel hollow rotating shaft is described in detail below.

[0238] As shown in FIGS. 25-26, the hollow rotating shaft 222 of the motor 221 is internally provided with a partition 228, which separates the internal space of the hollow rotating shaft 222 to form at least two channels.

[0239] Optionally, the at least two channels are arranged along the length direction of the hollow rotating shaft 222 respectively, and the input ends of the at least two channels are located at the first end face of the hollow rotating shaft 222 respectively, and the second end face of the hollow rotating shaft 222 is provided with openings respectively communicating with the at least two channels.

[0240] Based on this, in the embodiments of the present application, at least two third channels 227 are formed inside the hollow rotating shaft 222, so that one third channel 227 can be used for transmitting one kind of consumables, thereby avoiding the problem of mixing the residual substances of the consumables transmitted this time with the previous consumables in the pipeline.

[0241] The extending direction of the third channel 227 can be parallel to the axial direction of the hollow shaft 222. The number of the third channels 227 can be set according to actual needs. For example, referring to (a)-(e) in FIG. 27, when the number of the third channels 227 in the hollow shaft 222 is 2, the cross-sectional view of the hollow shaft 222 is shown. For example, referring to (a)-(c) in FIG. 28, when the number of the third channels 227 in the hollow shaft 222 is 3, the cross-sectional view of the hollow shaft 222 is shown. For example, referring to (a)-(c) in FIG. 29, when the number of the third channels 227 in the hollow shaft 222 is 4, the cross-sectional view of the hollow shaft 222 is shown. It should be noted that FIGS. 27-29 are only examples of some embodiments of the present application, and in fact, the cross-sectional shape and number of the third channels 227 can be adjusted according to needs. The number of the third channels 227 can be set to 2-8. For the acoustic motor, the number of the third channels 227 can be 2-4 due to the small volume of the shaft. If the number exceeds this range, the third channel 227 will be very narrow, and the single output of the material will be very small. The cross-sectional shape of each third channel 227 can be one or a combination of circular, elliptical, sector, semicircular, half-moon, polygonal, and irregular shapes. Moreover, each third channel 227 can be a straight pipe, a curved pipe, a spiral pipe, or an irregular pipe, which is not limited in the present application.

[0242] The cross-sectional shape of the hollow shaft 222 can be a circular pipe, a partially flat pipe, or a partially circular pipe. The partition 228 can be integrally formed with the hollow shaft 222, or the partition 228 can be formed by embedding a detachable partition in the hollow shaft 222.

[0243] In this embodiment, by setting the shaft as a hollow structure and forming at least two third channels 227 in the shaft, different third channels 227 in the at least two third channels 227 can form third channels 227 for different materials when the shaft is applied to a personal care device, and the mixing of materials can be avoided due to the independence of the different third channels 227. At the same time, since the third channels 227 are arranged in the interior of the shaft, the arrangement of the at least two third channels 227 does not require additional space in the personal care device, thereby facilitating the miniaturization design of the personal care device.

[0244] Optionally, the opening includes at least two sub-openings 150 corresponding to the at least two third channels 227, the at least two sub-openings 150 are relatively spaced apart, the third channel 227 extends from the first end face 130 to the corresponding sub-opening 150 in the second end face 140, and the sub-opening 150 forms an output end of the corresponding third channel 227.

[0245] It can be understood that each of the at least two third channels 227 extends from the first end surface 130 to the second end surface 140. The different third channels 227 are not connected to each other in the hollow rotating shaft 222.

[0246] In this embodiment, since each of the third channels 227 extends from the first end surface 130 to the second end surface 140, the different third channels 227 are not connected to each other in the hollow rotating shaft 222, so that the problem of mutual mixing of consumables between the different third channels 227 can be avoided.

[0247] Optionally, the interior of the hollow rotating shaft 222 is further provided with a mixing flow channel connecting the at least two third channels 227, and the mixing flow channel is used for mixing the at least two consumables. Optionally, the mixing flow channel can be connected to two or more third channels 227, the number of mixing flow channels can be one or more, and the plurality of mixing flow channels can be arranged in parallel or at different positions of the rotating shaft. The position arrangement of the different mixing flow channels can be used to realize the mixing of different consumables at different stages, and the present application does not limit this.

[0248] Correspondingly, when the interior of the hollow rotating shaft 222 is further provided with the mixing flow channel, the mixing flow channel can be arranged at any position of the hollow rotating shaft 222, so that the sub-opening of the second end surface 140 can be one or more, and the present application does not limit this.

[0249] In addition, during the operation of the personal care device, there can be a situation that two or more materials need to be mixed. For some multi-consumables to be mixed, the mixing time of the consumables needs to be controlled to achieve the maximum effect. Some consumables will be invalid or reduce the effect if mixed in advance, so it is also necessary to solve the problem of how to avoid the mixing of consumables at a non-target transmission period.

[0250] Based on this, in the embodiment of the present application, the mixing flow channel connected to the at least two third channels 227 is arranged in the hollow rotating shaft 222, so that the relative lengths of the third channels 227 and the mixing flow channel can be changed, that is, the mixing time of each consumable can be accurately controlled, thereby solving the problem of how to avoid the mixing of consumables at a non-target transmission period.

[0251] Specifically, when the consumables transmitted by the at least two third channels 227 need to be mixed at the same time, the lengths of the at least two third channels 227 can be the same, the output ends of the at least two third channels 227 are located on the same plane, the output ends of the at least two third channels 227 are respectively connected to the input ends of the mixing flow channel, and the output end of the mixing flow channel is located at the opening. In this way, the consumables in each third channel 227 can enter the mixing flow channel for mixing from the same position.

[0252] Correspondingly, when there are some consumables that need to be mixed first and some that need to be mixed later among the consumables transmitted by the at least two third channels 227, the length of the third channel 227 that transmits the consumables that need to be mixed first can be made smaller than the length of the third channel 227 that transmits the consumables that need to be mixed later, i.e., the consumables in each third channel 227 can enter the mixing flow channel from different positions for mixing.

[0253] In addition, when there are some consumables that need to be mixed first and some that need to be mixed later among the consumables transmitted by the at least two third channels 227, two mixing flow channels can be formed in the hollow rotating shaft 222, the consumables that need to be mixed first can be mixed for the first time through one mixing flow channel, and the consumables mixed for the first time and the consumables that need to be mixed later can be mixed for the second time through another mixing flow channel. Correspondingly, more than three mixing flow channels can be formed in the hollow rotating shaft 222 to be suitable for the scene where the consumables need to be mixed in at least three stages.

[0254] In this embodiment, by arranging the mixing flow channels that communicate with the at least two third channels 227 in the hollow rotating shaft 222, the relative lengths of the third channels 227 and the mixing flow channels can be changed, and the positions of the mixing flow channels can be changed, so that the mixing time of each consumable can be accurately controlled, thereby solving the problem of how to avoid the mixing of consumables at a non-target transmission time period and ensuring the maximization of the efficacy of the consumables.

[0255] Optionally, a one-way valve is arranged in each third channel 227, and the output end of the one-way valve faces the output end of the corresponding third channel 227. The one-way valve can be various types of one-way valves in the related art, for example, in some embodiments of the present application, the one-way valve can be a duckbill valve, a silica gel one-way valve, a Tesla valve, etc.

[0256] It can be understood that one one-way valve can be arranged in each third channel 227. In this way, the consumables can only flow from the input end to the output end of the third channel 227, and cannot flow back from the output end to the input end side of the third channel 227. In this embodiment, by arranging the one-way valve in the third channel 227, the problem of backflow of the consumables in the third channel 227 can be avoided.

[0257] Optionally, the hollow rotating shaft 222 is further provided with a processing device for processing the consumables, and the processing device can be arranged on the outer side wall of the rotating shaft or in the flow channel or the partition 228, which is not limited in the present application.

[0258] In this embodiment, the processing device is embedded in the partition 228, and the processing device includes at least one of the following devices: a temperature control plate, a catalyst plate with a catalyst for catalyzing the reaction of the consumables, a lamp plate, a radio frequency device, and a micro-current device.

[0259] Specifically, in order to promote the rapid release of active ingredients of the consumables and stimulate the efficacy of the consumables, the processing device can be embedded in the partition portion 228. In this way, the processing device can process the consumables during the transmission of the consumables in the third channel 227.

[0260] It can be understood that the processing devices corresponding to different third channels 227 in the at least two third channels 227 can be the same or different. In addition, different processing devices can be triggered when the personal care device is in different working modes.

[0261] The temperature control plate can be used to adjust the temperature of the consumables, for example, the consumables can be heated or cooled. The catalytic plate is used to catalyze the catalytic reaction of the consumables. The lamp plate can emit various types of light, for example, it can emit fluorescent light, ultraviolet light, infrared light, etc. The radio frequency device can output radio frequency signals. The micro-current device can output micro-currents.

[0262] When the processing device is embedded in the partition portion 228, the partition portion 228 can be formed by an independent component embedded in the inside of the hollow rotating shaft 222. In this way, during installation, the processing device can be embedded in the partition portion 228 first, and then the partition portion 228 can be embedded in the inside of the hollow rotating shaft 222.

[0263] In this embodiment, the processing device is embedded in the partition portion 228. In this way, the processing device can process the consumables during the transmission of the consumables in the third channel 227, thereby promoting the rapid release of active ingredients of the consumables and stimulating the efficacy of the consumables.

[0264] It should be noted that the processing device can also be arranged at other positions outside the partition portion 228. For example, in another embodiment of the present application, a part of the hollow rotating shaft 222 can be arranged as a transparent structure, which is referred to as a transparent segment. The processing device can be embedded in the outer side wall of the transparent segment. Since the side wall of the transparent segment is transparent, the signal output by the processing device can penetrate the transparent segment to process the consumables flowing through the transparent segment.

[0265] Optionally, the hollow rotating shaft 222 comprises a first segment 160, and the outer side wall of the first segment 160 is provided with a first plane 160a and a second plane 160b. The first plane 160a and the second plane 160b are opposite to each other, and the distance between the first plane 160a and the second plane 160b is less than the diameter of the hollow rotating shaft 222.

[0267] The cross-sectional shape of the first segment 160 matching the cross-sectional shape of the connecting hole 210 of the rotor support 200 in the motor can mean that the cross-sectional shape of the first segment 160 is the same as the cross-sectional shape of the connecting hole 210, and the cross-sectional size of the first segment 160 can be the same as the cross-sectional size of the connecting hole 210 of the rotor support 200.

[0269] The rotor set 223 of the motor 221 includes a rotor support 200 and a coil wound on the rotor support 200, and the rotor support 200 is formed by stacking a plurality of steel sheets. Please refer to FIG. 24, which is a structural schematic diagram of the rotor support 200 formed by stacking a plurality of steel sheets in a direction perpendicular to the paper. It can be understood that the structures of the steel sheets are the same, and FIG. 30 represents a structural schematic diagram of one of the steel sheets. Please refer to FIG. 30, the rotor support 200 includes a connecting portion 220, a first connecting arm 230, a second connecting arm 250, a first limiting portion 240, and a second limiting portion 260, the cross-sectional shape of the connecting portion 220 matches the cross-sectional shape of the first segment 160, and the connecting portion 220 is provided with a connecting hole 210 corresponding to the first segment 160, and the first segment 160 is arranged in the connecting hole 210, so that the rotor set can drive the rotating shaft to rotate synchronously during rotation;

[0270] The connecting portion 220 includes a first outer wall 220a and a second outer wall 220b opposite to each other, the first outer wall 220a is an outer wall of the connecting portion 220 opposite to the first plane 160a, the second outer wall 220b is an outer wall of the connecting portion 220 opposite to the second plane 160b, and the first outer wall 220a and the second outer wall 220b are respectively flat outer walls, the first limiting portion 240 is connected with the first outer wall 220a through the first connecting arm 230, and the first limiting portion 240 is arranged opposite to the first outer wall 220a, and the first limiting portion 240 and the first outer wall 220a form a first winding space; the second limiting portion 260 is connected with the second outer wall 220b through the second connecting arm 250, and the second limiting portion 260 is arranged opposite to the second outer wall 220b, and the second limiting portion 260 and the second outer wall 220b form a second winding space.

[0271] Optionally, the steel sheet can be a silicon steel sheet or a silicon steel sheet. The cross-sectional shape of the connecting portion 220 can be the same as that of the first segment 160, and the size of the outer contour of the cross-section of the connecting portion 220 is greater than the cross-sectional size of the first segment 160.

[0272] Referring to FIG. 24, the lengths of the first connecting arm 230 and the second connecting arm 250 are equal, and the length of the first connecting arm 230 forms the length of the first wire winding space, and the length of the second connecting arm 250 forms the length of the second wire winding space. Hereinafter, the length of the first connecting arm 230 and the length of the second connecting arm 250 are collectively referred to as the length L of the wire winding space. 绕线空间 .

[0273] The stator set 224 described above includes a stator support and a permanent magnet mounted on the stator support. It should be noted that the coils of the rotor set 223 can also be wound on the stator set 224, and the permanent magnet can be provided on the rotor set 223, which is not limited in the present application.

[0274] Referring further to FIGS. 17-18, the motor further includes two bearings 800 respectively arranged at both ends of the rotating shaft, one of which is embedded in the shaft hole of the front cover 225, and the other is embedded in the shaft hole of the rear cover 226. The rotating shaft passes through the two shaft holes and is connected to the two bearings 800.

[0275] The size of the rotating shaft in the existing motor (such as a sound wave motor) is small. In order to change the rotating shaft into a rotating shaft with multiple third channels 227, it is necessary to increase the size of the rotating shaft to ensure that the third channel 227 can pass through the target amount of consumables. However, when the size of the rotating shaft of the motor is increased, the wire winding space of the rotor set will inevitably be reduced.

[0276] Based on this, the present application provides a scheme that can increase the size of the rotating shaft of the motor without increasing the overall size of the motor and without affecting the reduction of the wire winding space of the rotor set. The present application improves the structure and shape of the rotating shaft by utilizing the space of the motor in the longitudinal direction. The first segment 160 of the rotating shaft is changed into a flat tube form, so that the rotating shaft can have enough space to set multiple flow channels, while maintaining the original size of the motor. The wire winding space is also increased, the number of turns of the coil is increased, and the performance of the motor such as the swing amplitude and the torque is improved.

[0277] The principle and beneficial effects of improving the rotating shaft according to the present application will be illustrated below:

[0278] The size of the hollow rotating shaft 222 in the direction from the first limiting portion 240 to the second limiting portion 260 is L 转轴 , and the total length of the steel sheet (i.e. the length between the first limiting portion 240 and the second limiting portion 260) is L 总长The size of the connecting hole 210 in the direction from the first limiting portion 240 to the second limiting portion 260 is L 穿槽 ; the length of the first winding space and the second winding space is L 绕线空间 ; L 绕线空间 =(L 总长 -L 穿槽 ) / 2.

[0279] It can be understood that L 穿槽 is determined by the size L 转轴 of the rotating shaft in the direction from the first limiting portion 240 to the second limiting portion 260, when the rotating shaft is a circular tube, L 转轴 is equal to the outer diameter of the rotating shaft, the size L 穿槽 of the connecting hole 210 is equal to L 转轴 of the rotating shaft, at this time, L 绕线空间 =(L 总长 -L 转轴 ) / 2. Taking the rotating shaft of the motor in the prior art as a circular tube, and the outer diameter of the rotating shaft is 3 mm, and the total length of the steel sheet is 10 mm as an example, L 绕线空间 =(10-3) / 2=3.5 mm.

[0280] In the embodiment of the application, in order to design two third passages 227 in the rotating shaft, the size of the motor rotating shaft needs to be increased, and the effective size needs to be at least 5 mm, so as to provide sufficient space to arrange the two third passages 227, and at the same time ensure a certain flow of consumables. Taking the circular rotating shaft as an example, when the outer diameter is 5 mm, the total length L 总长 of the steel sheet is 10 mm, then the winding space of the steel sheet becomes (10-5) / 2=2.5 mm. Compared with the winding space of 3.5 mm, the circular motor rotating shaft obviously reduces the winding space, so that the number of turns of the coil is reduced, and the performance of the motor is reduced (such as reducing the swing and torque of the motor).

[0281] If it is necessary to ensure the same winding space, a larger size steel sheet can also be used, for example, a 12 mm long steel sheet is used, which can also ensure that the winding space of the coil remains at the winding space of 3.5 mm of the existing motor, but in this way, the overall volume of the motor is increased.

[0282] Based on this, in the embodiment of the application, the space of the motor in the longitudinal direction is used, the first segment 160 of the rotating shaft is changed into a flat tube form, that is, the outer side wall of the first segment 160 is provided with a first plane 160a and a second plane 160b, and the first plane 160a and the second plane 160b are opposite to each other. As shown in FIG. 25, the first segment 160 is provided in a flat tube shape in the embodiment of the application, so that the effective size (that is, the size in the longitudinal direction shown in FIG. 24, which is the long side size of the flat tube) L 有效5mm, so that there is enough space to arrange two third channels 227 along the length direction of the long side of the flat tube, and the size L of the flat tube in the direction from the first limiting portion 240 to the second limiting portion 260 转轴 , the slot size L of the steel sheet 穿槽 is equal to the size L of the flat tube in the direction from the first limiting portion 240 to the second limiting portion 260 转轴 , L 转轴 may be set to 2-3mm, so that the size of the two third channels 227 can be designed as (1.5-2)*(2-3)mm, and (1-2)mm space can be reserved as the wall thickness of the flow channel, which not only meets the wall thickness requirement, but also provides enough flow channel space for the consumable to flow. At this time, the winding space L 绕线空间 of the steel sheet is 3.5-4mm, compared with the existing winding space, the improved rotating shaft increases the winding space of the motor, which is beneficial to improve the performance of the motor.

[0283] In this embodiment, by setting the first segment 160 of the rotating shaft as a flat tube in the direction from the first limiting portion 240 to the second limiting portion 260, the third channel 227 can be arranged in the hollow rotating shaft 222 while ensuring that there is enough space inside the hollow rotating shaft 222, and the original volume of the motor is maintained, and the performance of the motor is improved.

[0284] The consumable input end of the hollow rotating shaft 222 is changed to a flat tube form, which can also facilitate the connection of the hollow rotating shaft 222 with other consumable input devices (such as the hose of a peristaltic pump), convenient assembly, and the flat tube form also facilitates the production and manufacturing of the rotating shaft.

The above-mentioned cross sections are respectively perpendicular to the first plane 160a and the second plane 160b, which specifically means that the cross section is the cross section of the first segment 160 perpendicular to the first plane 160a and perpendicular to the second plane 160b.

[0287] Please refer to FIG. 19, the at least two third channels 227 can be arranged along the long side direction of the cross section of the first segment 160 shown in FIG. 19.

[0288] In this embodiment, by arranging the at least two third channels 227 along the direction in which the long side of the cross section of the first segment 160 extends, more third channels 227 can be arranged in the hollow rotating shaft 222, thereby improving the utilization of the internal space of the hollow rotating shaft 222.

[0290] Optionally, the cross-sectional shape of the second segment 170 can be circular or flat.

[0295] Since the arrangement of the plurality of third passages 227 of the hollow rotating shaft 222 can be longitudinal, transverse or irregular, the arrangement of the plurality of fourth passages 312 of the nursing head 31 can also be longitudinal, transverse or irregular, and the positions of the passages of the two are not necessarily one-to-one corresponding, therefore, in order to facilitate the communication of the passages of the hollow rotating shaft 222 and the nursing head 31, optionally, the adapter 34 comprises a first adapter 341 and a second adapter 342, the first adapter 341 and the second adapter 342 are provided with corresponding perforations and adapter grooves communicating the corresponding perforations, when the two form a sealed connection, the perforations and the adapter grooves communicate to form an adapter passage communicating the corresponding third passage 227 of the hollow rotating shaft 222 and the corresponding fourth passage 312 of the nursing head 31.

[0296] Preferably, in order to reasonably utilize the space of the second power device 22 and the nursing head 31, arrange larger space passages to increase the flow of a single consumable flow channel, in this specific embodiment, the two third passages 227 of the hollow rotating shaft 222 are arranged longitudinally in parallel, the two fourth passages 312 of the nursing head 31 are arranged transversely in parallel, through the perforations and the adapter grooves of the first adapter 341 and the second adapter 342, the third passage 227 can be connected with the corresponding fourth passage 312 one-to-one, forming an independent flow channel.

[0297] The nursing head 31 of the embodiment of the present application is described in more detail below.

[0300] The consumable can be a consumable that can flow in the fourth channel 312, for example, the consumable can be any one of an oral care material, a hair care material, and a skin care material. For example, the oral care material includes toothpaste, mouthwash, etc., the hair care material includes shaving foam, shampoo, etc., and the skin care material includes facial cleanser, skin care product, etc. The care head can be any one of an oral care head, a hair care head, and a skin care head.

[0301] It can be understood that in the above-mentioned care head 31, a partition plate can be formed between adjacent fourth channels 312 to separate different fourth channels 312 from each other. The partition plate can be integrally formed with the shell of the care head 31. Alternatively, the partition plate can be assembled with the shell of the care head 31.

[0302] The feed inlet of the above-mentioned care head 31 can include at least two sub-feed inlets corresponding to the above-mentioned at least two fourth channels 312, and each sub-feed inlet is in communication with the input end of the corresponding fourth channel 312. In other embodiments of the present application, the feed inlet can also be formed by the input ends of the above-mentioned at least two fourth channels 312, that is, the feed inlet includes the input ends of the at least two fourth channels 312.

[0303] The discharge outlet 311 of the above-mentioned care head 31 can include at least two sub-discharge outlets corresponding to the above-mentioned at least two fourth channels 312, and each sub-discharge outlet is in communication with the input end of the corresponding fourth channel 312.

[0307] In addition, the shape and size of the fourth channel 312 can change with the shape trend of the care head 31, for example, when the care head 31 is a columnar brush rod, the diameter gradually decreases from the consumable input end to the consumable output end, and correspondingly, the diameter of the fourth channel 312 gradually decreases from the consumable input end to the consumable output end.

[0308] In this embodiment, by providing at least two fourth channels 312 in the care head 31, when the care device can output two or more consumables, different consumables can be transmitted through different fourth channels 312, that is, each fourth channel 312 is only used to transmit one fixed consumable, thereby avoiding the problem of mixing between different consumables due to multiplexing the same fourth channel 312 by different consumables, thereby facilitating the user's experience.

[0309] Optionally, the care head 31 comprises a discharge end face 313, and the discharge port 311 is located on the discharge end face 313; wherein the discharge end face 313 is the end face of the care head 31 for outputting consumables. The direction perpendicular to the discharge end face 313 of the care head 31 is the thickness direction of the care head 31.

[0310] Optionally, the at least two fourth channels 312 are arranged in a parallel arrangement, an offset arrangement, or a combination thereof. As shown in FIG. 37, the direction perpendicular to the discharge end face 313 is defined as the Z-axis direction, and the two directions parallel to the discharge end face 313 and perpendicular to each other are defined as the Y-axis direction and the X-axis direction, respectively, wherein the Y-axis direction is consistent with the central axis direction of the care head 31. Referring to FIG. 38(a), optionally, the at least two fourth channels 312 are arranged in parallel along the X-axis direction. Referring to FIG. 38(b), optionally, the at least two fourth channels 312 are arranged in parallel along the Z-axis direction. Referring to FIG. 38(c), optionally, the at least two fourth channels 312 are arranged in an offset manner.

[0311] It should be understood that the parallel arrangement and parallel arrangement of the at least two fourth channels 312 means that the at least two fourth channels 312 are arranged side by side, and the shapes thereof can be the same or different.

[0312] It can be understood that the above embodiments are examples of the case where the fourth channels 312 are straight flow channels. In fact, when the fourth channels 312 are in other forms other than straight, the arrangement of the at least two fourth channels 312 can also be arranged in a similar manner as (a) to (c) in FIG. 38, for example, when the fourth channels 312 are curved, the relative positions between the at least two fourth channels 312 are the same in any cross section of the care head 31, and the at least two fourth channels 312 are arranged side by side in the Z-axis direction or the X-axis direction in any cross section of the care head 31, or the at least two fourth channels 312 are arranged in a staggered manner in any cross section of the care head 31.

[0313] In the embodiments of the present application, the at least two fourth channels 312 are arranged in a side-by-side manner and spaced apart in the care head 31. Since the discharge end surface 313 of the care head 31 usually needs to reserve a certain thickness space for the installation of output components, for example, the discharge end surface 313 of the electric toothbrush usually needs to reserve a bristle planting space for the bristles, and for example, for the care instrument or massage instrument, it is usually necessary to arrange a care head or massage head in the thickness direction of the care head 31. Therefore, the thickness dimension of the care head 31 is usually small, and therefore, if the at least two fourth channels 312 are arranged in the thickness direction of the care head 31, due to the limitation of the thickness space, the cross-sectional area of the fourth channel 312 may be too small to meet the flow requirement.

[0314] Specifically, taking the care head as a brush head as an example, due to the space limitation of the bristle planting area of the brush head, if the fourth channels 312 in the brush head are arranged in the extension direction of the bristles (i.e., the Z-axis direction of FIG. 37), when multiple fourth channels 312 are arranged without increasing the thickness of the head of the brush head, it will occupy the bristle planting space, increase the bristle planting difficulty, and affect the mass production of the brush head. For example, if the thickness of the brush head is 4 mm, the size of 2 fourth channels 312 needs to be about 3.5 mm, and the remaining 0.5 mm wall thickness, if still needs to be planted, will result in insufficient bristle planting space and great bristle planting difficulty. Moreover, due to the space limitation, if the size of the fourth channel 312 is small, the flow will be affected and the resistance of the pump will be increased. If the thickness of the head of the brush head and the diameter of the brush handle are increased to provide enough space to arrange two fourth channels 312, although this can ensure a certain flow of consumables, but the volume of the brush head is increased, which may cause the user to feel uncomfortable when entering the user's mouth.

[0315] Therefore, in order to ensure the flow of consumables without increasing the size of the brush head, in the embodiment of the present application, at least two fourth channels 312 are arranged side by side along the X-axis direction shown in FIG. 37. Since the X-axis direction is perpendicular to the thickness direction of the care head 31, compared with the single fourth channel 312 in the related art, the at least two fourth channels 312 do not increase the thickness space required by the fourth channel 312. In this way, multiple consumable fourth channels 312 can be opened without increasing the head thickness and the diameter of the brush rod of the care head 31, and the production and manufacturing are facilitated, and a larger fourth channel 312 can be arranged in a smaller brush head space to ensure the flow of consumables.

[0316] It can be understood that the fourth channel 312 can extend along the length direction of the care head 31, that is, the fourth channel 312 can extend along the Y-axis direction in FIG. 37.

[0317] In this embodiment, at least two fourth channels 312 are arranged side by side along the X-axis direction shown in FIG. 37. In this way, multiple consumable fourth channels 312 can be opened without increasing the head thickness and the diameter of the brush rod of the care head 31, and the production and manufacturing are facilitated, and a larger fourth channel 312 can be arranged in a smaller brush head space to ensure the flow of consumables.

[0318] It should be understood that in order to ensure the flow of consumables without increasing the size of the brush head, the present application also provides two other embodiments: first, at least two fourth channels 312 are arranged along the Z-axis direction shown in FIG. 39, and a section of the fourth channel 312 close to the discharge end face 313 can be arranged in an irregular shape to ensure the flow of consumables. Second, the inlet section of the at least two fourth channels 312 can also be offset, and a section of the fourth channel 312 close to the discharge end face 313 can be arranged in an irregular shape to ensure the flow of consumables.

[0319] It should also be understood that when the care head is other care heads and massage heads, the size is not limited, and at least two fourth channels 312 can also be arranged along the Z-axis direction shown in FIG. 37, which is not limited by the present application.

[0320] Optionally, an installation channel 104 is arranged at one end of the care head 31 away from the discharge port 311 of the care head 31, and the installation channel 104 is used to communicate the consumable input end and the at least two fourth channels 312.

[0321] Specifically, one end of the installation channel 104 is located at the first end of the care head 31, and the other end of the installation channel 104 communicates with the input end of the at least two fourth channels 312; the inner wall of the installation channel 104 is provided with a clamping portion 32a for clamping with a driving shaft of the personal care device.

[0322] It can be understood that after the driving shaft of the personal care device is connected with the care head 31, the driving shaft can drive the care head 31 to move mechanically, and the mechanical movement of the care head 31 is combined with the automatic output of the consumables to promote the application of the consumables. For example, the care head 31 is a brush head, the driving shaft of the personal care device corresponds to a hollow ultrasonic motor shaft, and the hollow ultrasonic motor shaft can output the consumables while driving the brush head to vibrate, so as to realize the automatic output of the toothpaste and the operation of brushing teeth, thereby facilitating the use of the user. For example, the care head 31 is a massage head of a skin care instrument, the hollow motor shaft of the skin care instrument can output the skin care product while driving the massage head to rotate and / or vibrate, so as to realize the automatic output of the skin care product while enabling the massage head to realize the massage operation.

[0323] The clamping portion 32a can be a protrusion on the inner wall of the mounting channel 104, or a clamping piece 32 can be arranged in the mounting channel 104, and the inner side wall of the clamping piece 32 is provided with the clamping portion 32a. For example, referring to FIGS. 34-37, in some embodiments of the present application, the care head further includes a clamping piece 32, which is a hollow structure for mounting the driving shaft of the personal care device, and the inner side wall of the clamping piece 32 forms one or more protrusions to form the clamping portion 32a.

[0324] It can be understood that the mounting channel 104 is clamped with the consumable input end through the clamping portion 32a or the clamping piece 32. Optionally, the clamping piece 32 is connected with the care head 31 by any one of clamping, bonding, threaded connection, etc.

[0325] Specifically, in the embodiments of the present application, the clamping piece 32 is mounted in the mounting channel 104 by clamping. More specifically, the outer side wall of the clamping piece 32 is provided with a protrusion, the mounting channel 104 is provided with a groove matched with the protrusion, and the protrusion is clamped in the groove, so as to form a clamping connection state of the clamping piece 32 and the care head 31.

[0326] It can be understood that the protrusion and the groove can also be reversely arranged, that is, the protrusion can be arranged on the inner wall of the mounting channel 104, and the groove can be arranged on the outer side wall of the clamping piece 32, which is not limited in the present application. The protrusion and the groove can be one or more, and the number thereof is also not limited in the present application.

[0327] In this embodiment of the present application, the outer side wall of the clamping piece 32 is provided with two protrusions, including a first protrusion 117 and a second protrusion 118, and the inner side wall of the clamping piece 32 is provided with a third protrusion, which forms the clamping portion 32a. The mounting channel 104 is provided with grooves corresponding to the first protrusion 117 and the second protrusion 118, respectively.

[0328] It can be understood that the number of the protrusions and the grooves is not limited, the protrusions can be single square or arc-shaped bumps, or annular protrusions extending around the inner side wall or the outer side wall, and the specific shape of the protrusions is not limited in the present application.

[0329] In some embodiments of the present application, the drive shaft of the personal care device can include a clamping groove corresponding to the third protrusion (i.e., the clamping portion 32a), and when the drive shaft is connected to the care head, the third protrusion is embedded in the clamping groove to realize the clamping between the drive shaft and the care head.

[0330] In this embodiment, by providing the clamping portion 32a for clamping with the drive shaft of the personal care device on the inner wall of the mounting channel 104, the care head can be connected to the drive shaft through the clamping portion 32a.

[0331] Optionally, the care head 31 is provided with a connecting channel between the mounting channel 104 and the at least two fourth channels 312, and the mounting channel 104 communicates with the at least two fourth channels 312 through the connecting channel.

[0332] The care head further comprises an adapter provided in the connecting channel, and the adapter is used to communicate the consumable input end and the at least two fourth channels 312.

[0333] The adapter is provided with an inlet through hole and an outlet through hole on two sides respectively, the inlet through hole communicates with the consumable input end, and the outlet through hole communicates with the corresponding fourth channel 312; the adapter further comprises an adapter groove, which communicates with the inlet through hole and the outlet through hole respectively, so that the inlet through hole and the outlet through hole are communicated through the adapter groove, and the inlet through hole, the adapter groove and the outlet through hole form a transition flow channel for communicating the consumable input end and the corresponding fourth channel 312.

[0334] It is worth mentioning that the consumable input end can be a consumable outlet of a handle of the personal care device, specifically, it can be a hollow drive shaft of the personal care device, or other consumable output interfaces of the personal care device, which are not limited in the present application.

[0335] Specifically, in the embodiments of the present application, the adapter comprises a first adapter 341 and a second adapter 342, the first adapter 341 and the second adapter 342 are stacked in the connecting channel, the second adapter 342 is located on the side of the first adapter 341 away from the at least two fourth channels 312, and the first adapter 341 and the second adapter 342 form at least two transition flow channels for communicating the consumable input end and the corresponding fourth channel 312.

[0336] Further, the first adapter 341 is provided with at least two third through holes 108 (i.e., discharge through holes) corresponding to the at least two fourth channels 312, the third through holes 108 are arranged opposite to the input ends of the corresponding fourth channels 312, and the first adapter 341 is further provided with a first transition groove communicating the third through holes 108; the second adapter 342 is provided with at least two fourth through holes 110 (i.e., feeding through holes) corresponding to the at least two third through holes 108, and the second adapter 342 is further provided with a second transition groove communicating the fourth through holes 110; wherein the first transition groove and the second transition groove form a transition groove of the adapter. In the embodiment of the present application, the third through holes 108, the first transition groove, the second transition groove and the fourth through holes 110 form a transition flow channel.

[0337] It is worth mentioning that, in the embodiment of the present application, the side wall of the first adapter 341 and the side wall of the second adapter 342 are respectively attached to the inner wall of the connecting channel, and the first end surface of the first adapter 341 is attached to the input end of the at least two fourth channels 312, so as to ensure the sealing of the consumable flow channel and avoid the problem of material leakage.

[0338] Specifically, in addition to the above-mentioned care head, the personal care device usually further includes a handle 120 as shown in FIG. 37, and the main components such as the feeding assembly and the driving assembly in the personal care device are usually arranged in the handle 120. In order to ensure the independent transmission of each consumable, at least two feeding channels 121 (in an embodiment, the feeding channel is a third channel 227 of a hollow rotating shaft 222 of a motor 221) corresponding to the at least two fourth channels 312 are usually arranged in the handle 120. Since the arrangement direction of the feeding channel 121 and the at least two flow channels 101 may not be consistent, for example, referring to FIG. 37, in some embodiments of the present application, the at least two feeding channels 121 are arranged along the thickness direction of the care head 31, i.e., the arrangement direction of the at least two feeding channels 121 is the Z-axis direction, which is perpendicular to the X-axis direction, while the at least two flow channels 101 are arranged along the X-axis direction. Since the arrangement directions of the at least two flow channels 101 and the at least two feeding channels 121 are different, the consumable outlet of the feeding channel 121 and the consumable input port of the flow channel 101 are not aligned, therefore, in order to facilitate the butt joint of the at least two feeding channels 121 and the at least two flow channels 101, in the embodiment of the present application, the first adapter 341 and the second adapter 342 are arranged, and the direction of the flow channel 101 is changed through the first adapter 341 and the second adapter 342, so as to realize the one-to-one correspondence and communication between the at least two feeding channels 121 and the at least two flow channels 101.

[0339] That is to say, by arranging the adapter, the care head can be adapted to the consumable input end inputting the consumables from different positions or directions, i.e., the care head is suitable for connecting with different types of consumable input ends, thereby increasing the application range of the care head.

[0340] It should be understood that when the at least two flow channels 101 are arranged along the Z-axis direction, that is, the flow channels 101 are arranged in the same direction as the corresponding feeding channels 121, the positions of the consumable outlets of the feeding channels 121 and the consumable inlets of the flow channels 101 are aligned, and the adapter of the care head 31 can be selectively arranged, that is, the care head 31 can be arranged with or without the adapter.

[0341] In particular, the position of the fourth through hole 110 corresponds to the position of the consumable inlet, and by arranging the transition flow channel, the position of the third through hole 108 can correspond to or not correspond to the position of the fourth through hole 110, that is, the third through hole 108 can be arranged in the same direction as the fourth through hole 110 or be arranged in a staggered manner, and the present application does not limit this.

[0342] In some embodiments, a third adapter plate with a third transition groove can also be arranged between the second adapter 342 and the consumable inlet or between the first adapter 341 and the second adapter 342, that is, the adapter can include two or more adapter plates, and the two or more adapter plates form the transition flow channel through the cooperation of the transition grooves and the through holes, and the present application does not limit the number of adapter plates. By arranging the transition flow channel, the flow direction of the consumables can be changed to facilitate the connection of the care head with the handle 120 of the personal care device. Optionally, the first transition groove 109 is opened in the second end surface of the first adapter 341, wherein the first transition groove 109 communicates the corresponding third through hole 108 and the fourth through hole 110, so that the consumables entering from the fourth through hole 110 can flow through the first transition groove 109, enter the corresponding third through hole 108, and enter the corresponding flow channel 101 through the third through hole 108. The second end surface of the first adapter 341 is the end surface of the first adapter 341 close to the second adapter 342.

[0343] Optionally, the second transition groove 111 is opened in the first end surface of the second adapter 342, wherein the second transition groove 111 communicates the corresponding third through hole 108 and the fourth through hole 110, so that the consumables entering from the fourth through hole 110 can flow through the second transition groove 111, enter the corresponding third through hole 108, and enter the corresponding flow channel 101 through the third through hole 108. The first end surface of the second adapter 342 is the end surface close to the first adapter 341.

[0344] That is, the transition flow channel comprises a first transition groove 109 formed in the second end surface of the first adapter 341, and a second transition groove 111 formed in the first end surface of the second adapter 342, wherein the second end surface of the first adapter 341 is the end surface of the first adapter 341 close to the second adapter 342, and the first end surface of the second adapter 342 is the end surface of the second adapter 342 close to the first adapter 341; the first transition groove 109 is in communication with the corresponding third through hole 108, and the first transition groove 109 is in communication with the second transition groove 111, and the second transition groove 111 is in communication with the corresponding fourth through hole 110.

[0345] When the transition flow channel comprises the first transition groove 109 and the second transition groove 111, the cross-sectional shapes of the first transition groove 109 and the second transition groove 111 can be the same, and the edges are arranged in alignment, at this time, the third through hole 108, the first transition groove 109, the second transition groove 111 and the fourth through hole 110 are in communication in turn, in this way, the communication area of the transition groove can be increased.

[0346] It should be noted that the fourth through hole 110 corresponding to the second transition groove 111 refers to the fourth through hole 110 in communication with the second transition groove 111.

[0347] In this embodiment, by arranging the first adapter 341 and the second adapter 342, the direction of the flow channel 101 is changed, so that at least two supply channels 121 and at least two flow channels 101 can be in one-to-one correspondence and in communication.

[0348] It should be noted that in the embodiment shown in FIG. 37, the through hole arrangement direction of the first adapter 341 and the second adapter 342 is perpendicular. In other embodiments of the present application, the arrangement direction of the through holes of the first adapter 341 and the second adapter 342 can also be non-perpendicular, in this way, the arrangement direction of the through holes of the first adapter 341 and the second adapter 342 is arranged at an angle, that is, in the embodiments of the present application, the relative positions of the third through hole 108 and the fourth through hole 110 are not limited, and they can be arranged in relative or staggered positions, as long as they can be communicated through the first adapter 341 and the second adapter 342.

[0349] Optionally, the care head further comprises a second sealing member 33, the second sealing member 33 is embedded in the mounting channel 104 and arranged between the clamping member 32 and the adapter, for sealing the consumable flow channel and preventing leakage during consumable transmission.

[0350] Specifically, in the embodiment of the present application, the second sealing member 33 abuts against the second end surface of the second adapter 342, and the side wall of the second sealing member 33 is sealingly connected to the inner wall of the mounting channel 104. The clamping portion 32a is located between the second sealing member 33 and the first end 103 of the care head 31. The second end surface of the second adapter 342 is the end surface of the second adapter 342 facing away from the first adapter 341.

[0351] Further, the second sealing member 33 is provided with a connecting groove 113 at an end thereof facing away from the second adapter 342. The connecting groove 113 is in communication with the consumable input end, and the groove bottom is provided with at least two fifth through holes 114 corresponding to the at least two fourth through holes 110 (i.e., the feeding through holes). The fifth through holes 114 are oppositely arranged with the corresponding fourth through holes 110.

[0352] Please refer to FIG. 32, the second sealing member 33 can abut between the clamping member 32 and the second adapter 342. Please refer to FIG. 34, the drive shaft of the personal care device can be inserted into the connecting groove 113, and the drive shaft can be sealingly connected to the connecting groove 113. The above-mentioned feeding channel 121 can be a channel provided in the interior of the drive shaft, and the output end of the feeding channel 121 is opposite to the second end surface of the second adapter 342.

[0353] Among them, the second sealing member 33 can be various types of sealing members, for example, can be rubber sealing member or silica gel sealing member, etc. In this embodiment, by setting the second sealing member 33 in the mounting channel 104, thus, it is beneficial to improve the sealing performance of the care head, thereby reducing the risk of leakage of the consumable at the care head.

[0354] Optionally, the discharge port 311 is provided with a third one-way valve, and the input end of the third one-way valve is in communication with the output end of the at least two fourth channels 312. Alternatively, each fourth channel 312 is provided with a one-way valve therein, and the output end of the one-way valve faces the output end of the corresponding fourth channel 312.

[0355] Optionally, as shown in FIGS. 39 and 40, the third one-way valve 36 includes a plurality of one-way valve bodies, the top of the plurality of one-way valve bodies is concave to form a concave cavity, and the top of the plurality of one-way valve bodies is provided with a plurality of cutouts 371.

[0356] The third one-way valve 36 can be understood as a multi-channel one-way valve, and the top of the multi-channel one-way valve is concave to form a concave cavity, and the plurality of cutouts 371 are in communication with the concave cavity. The advantage of setting the concave cavity is that it can concentrate the output of the consumable and avoid spilling from both sides to cause the consumable to drop. The concave cavity can be a V-shaped concave cavity or a U-shaped concave cavity.

[0357] It should be noted that the cutout of the third one-way valve 36 can also be referred to as an outlet, and both have the same meaning and are used for outputting the consumable.

[0358] Optionally, the multi-channel one-way valve is a double-channel (double-opening) one-way valve, comprising a one-piece first one-way valve body 361a and a second one-way valve body 361b, the first one-way valve body 361a is provided with a first cutout 371a in communication with the corresponding fourth channel 312 of the nursing head 31; the second one-way valve body 361b is provided with a second cutout 371b in communication with the corresponding fourth channel 312 of the nursing head 31.

[0359] Optionally, each of the plurality of cutouts 371 is inclined towards the middle of the recessed cavity, so as to concentrate the consumables in the middle of the recessed cavity.

[0360] Each of the plurality of cutouts 371 is inclined to extend towards the middle of the recessed cavity, that is, each of the plurality of cutouts 371 has a guide slope for guiding the consumables to output to the middle of the recessed cavity, which can ensure that the consumables are concentrated in the middle of the third one-way valve 36.

[0361] The third one-way valve 36 of the embodiment of the present application is described in more detail below. In order to simplify the description, the third one-way valve 36 is described as a one-way valve in the following description of the third one-way valve.

[0362] Referring to FIGS. 41-48, the one-way valve comprises a valve body 360, the valve body 360 is internally provided with a flow channel, one end of the valve body 360 is provided with a fluid inlet in communication with the flow channel, the end face of the other end of the valve body 360 is a valve face, the valve face is provided with a cutout, the cutout is configured to pass through the surface of the valve face to the flow channel, and the cutout is configured to be opened by the pressure of the fluid entering the flow channel; at least part of the area of the valve face is configured as a recessed portion 362 recessed towards the inside of the valve body, and the cutout is located in the recessed portion 362.

[0363] In the related art, the valve face of the one-way valve is a flat surface or a convex surface protruding away from the valve body. After the material flows out of the cutout on the valve face, it directly scatters and spills out uncontrollably, which can cause the material to spill and drop when the material has not completely covered the required area, resulting in waste of the material. In the present embodiment, at least part of the area of the valve face is configured as a recessed portion 362 recessed towards the inside of the valve body, and the cutout is located in the recessed portion 362. The recessed portion 362 serves as a buffer space, which controls the fluid in the recessed portion 362 after the fluid flows out of the cutout, avoiding the problem of material waste caused by uncontrollable material.

[0364] It should be noted that the specific structure of the recess 362 can be various. In some embodiments of the present embodiment, at least in the first direction (the X direction in FIG. 43), the valve surface includes two first protrusions 363 arranged at intervals, the first protrusions 363 are arranged protruding away from the valve body, and the space enclosed by the two first protrusions 363 forms the recess 362, wherein the first direction is parallel to the radial direction of the valve body 360.

[0365] At least in the first direction, the valve surface includes two first protrusions 363 arranged at intervals, the extension direction of the first protrusions 363 is parallel to the axial direction of the valve body 360, and the first protrusions 363 are arranged extending away from the valve body 360, and the cutout is located in the recess 362 between the two first protrusions 363.

[0366] The arrangement of the two first protrusions 363 can control the flow direction of the fluid, so that the fluid flows along a second direction perpendicular to the first direction (the second direction is perpendicular to the axial direction of the valve body 360). For example, a one-way valve is arranged on a toothbrush, the brush head of the toothbrush is generally in a strip-shaped structure, when the one-way valve is arranged, the long side direction of the brush head can be perpendicular to the first direction, so that when the toothpaste flows out of the one-way valve to the toothbrush, it can flow along the long side direction of the brush head, and the toothpaste overflowing and dripping from the short side direction can be avoided.

[0367] Optionally, a plurality of first protrusions 363 are arranged in the circumferential direction of the valve body 360, and the plurality of first protrusions 363 and the area between the plurality of first protrusions 363 on the valve surface form a containing groove.

[0368] Optionally, the two first protrusions 363 are arranged on the edge regions of the valve surface on the opposite sides in the first direction, and the outer surface of one first protrusion 363 away from the other first protrusion 363 is connected with the corresponding outer surface of the valve body 360.

[0369] It should be noted that the connection form of the outer surface of one first convex part 363 away from the outer surface of another first convex part 363 and the corresponding outer surface of the valve body 360 includes flush and / or uneven cases. For example, the two first convex parts are defined as a first sub-convex part and a second sub-convex part, respectively, the outer surface of the first sub-convex part away from the second sub-convex part is flush with the corresponding outer surface of the valve body 360, and the outer surface of the second sub-convex part away from the first sub-convex part is flush with the corresponding outer surface of the valve body 360; or, the outer surface of the first sub-convex part away from the second sub-convex part is uneven with the corresponding outer surface of the valve body 360, and the outer surface of the second sub-convex part away from the first sub-convex part is uneven with the corresponding outer surface of the valve body 360; or, the outer surface of the first sub-convex part away from the second sub-convex part is flush with the corresponding outer surface of the valve body 360, and the outer surface of the second sub-convex part away from the first sub-convex part is uneven with the corresponding outer surface of the valve body 360; or, the outer surface of the first sub-convex part away from the second sub-convex part is uneven with the corresponding outer surface of the valve body 360, and the outer surface of the second sub-convex part away from the first sub-convex part is flush with the corresponding outer surface of the valve body 360.

[0370] The above scheme can increase the distance between the two first convex parts 363, thereby increasing the size of the space formed by the two first convex parts 363 and the area between the two first convex parts 363, thereby more effectively preventing material overflow. Moreover, the outer surface of one first convex part 363 away from the outer surface of another first convex part 363 flush with the corresponding outer surface of the valve body 360 can increase the aesthetic appearance of the one-way valve.

[0371] Referring to FIG. 43, optionally, the first convex part 363 includes a top end surface 364 of one end of the valve body 360, and the top end surface 364 is a curved surface. The curved surface arrangement can avoid injury to the user or other components in actual application, for example, when applied to a toothbrush, it can avoid injury to the gums when brushing teeth.

[0372] Illustratively, the top end surface 364 is a convex surface convexly arranged away from the valve body 360, so that the fluid flow is smoother.

[0373] Illustratively, the valve body 360 and the first convex part 363 are integrally formed, and the material of the valve body 360 and the material of the first convex part 363 are also the same, which can adopt soft or silicone flexible materials, so as to protect the corresponding parts of the user when the one-way valve is applied to articles such as toothbrushes, for example, to protect the gums.

[0374] Optionally, the recess 362 comprises a side surface 365 and a concave bottom surface 366, which are divided by a dashed line in FIG. 43 (it should be noted that the dashed line in FIG. 43 is only for better illustrating the positional relationship between the side surface 365 and the concave bottom surface 366, and in fact, the dashed line does not exist), and the side surface 365 is formed by one side of the first convex part 363 close to the other first convex part 363; the side surface 365 is a curved surface or a flat surface, and at least a part of the concave bottom surface 366 is at least one of a flat surface, a concave surface and a convex surface.

[0375] It should be noted that when the side surface 365 is a curved surface, the curved surface can be a concave surface or a convex surface.

[0376] The side surface 365 can be a concave surface, that is, one side of the first convex part 363 close to the other first convex part 363 can be a concave surface, that is, a surface concave to the direction away from the other first convex part 363, so as to increase the size of the recess 362, accommodate more fluid, more effectively prevent material overflow, and also make the fluid flow out of the cutout more smoothly.

[0377] The side surface 365 can be a convex surface, that is, one side of the first convex part 363 close to the other first convex part 363 can be a convex surface, that is, a surface convex to the direction close to the other first convex part 363, so as to increase the blocking force.

[0378] The side surface 365 can be a flat surface, that is, one side of the first convex part 363 close to the other first convex part 363 can also be a flat surface, which can be arranged parallel to the axial direction of the valve body 360 or inclined to the axial direction of the valve body 360; when the flat surface is arranged inclined to the axial direction of the valve body 360, the cross section of the two first convex parts 363 and the area between the two convex parts on the valve surface forms an inverted trapezoidal structure, that is, the distance between the two convex parts gradually increases along the direction away from the valve body 360, more effectively preventing material overflow.

[0379] It should be noted that the recess 362 comprises two side surfaces 365 located at opposite sides of the concave bottom surface 366, and the two side surfaces 365 can have the same structure or different structures, and the specific structure of the two side surfaces 365 can be as follows:

[0380] The two side surfaces 365 can be curved surfaces, wherein the two side surfaces 365 can be convex surfaces or concave surfaces, or one of the two side surfaces 365 is a convex surface and the other is a concave surface.

[0381] The two side surfaces 365 can also be planes, wherein the two side surfaces can be arranged parallel to the axial direction of the valve body 360, or arranged inclined to the axial direction of the valve body 360, or one of the two side surfaces 365 is arranged parallel to the axial direction of the valve body 360, and the other of the two side surfaces 365 is arranged inclined to the axial direction of the valve body 360.

[0382] One of the two side surfaces 365 is a curved surface, and the other of the two side surfaces 365 is a plane, specifically, one of the two side surfaces 365 is a convex surface, and the other of the two side surfaces 365 is a plane arranged parallel to the axial direction of the valve body 360; or one of the two side surfaces 365 is a convex surface, and the other of the two side surfaces 365 is a plane arranged inclined to the axial direction of the valve body 360; or one of the two side surfaces 365 is a concave surface, and the other of the two side surfaces 365 is a plane arranged parallel to the axial direction of the valve body 360; or one of the two side surfaces 365 is a concave surface, and the other of the two side surfaces 365 is a plane arranged inclined to the axial direction of the valve body 360.

[0383] Optionally, the junction of the side surface 365 and the concave bottom surface 366 is a curved surface with smooth transition or a plane.

[0384] It should be noted that at least part of the concave bottom surface 366 is at least one of a plane, a concave surface and a convex surface, and the number of regions of the concave bottom surface 366 being a plane, a concave surface or a convex surface can be set according to actual needs, and the arrangement mode can be set according to actual needs, for example, when the concave bottom surface 366 is at least two of a plane, a concave surface and a convex surface, the concave bottom surface 366 can be in a grid pattern shape or a stripe pattern shape. When the concave bottom surface 366 is in a stripe pattern shape, the extension direction of at least two of the plane, the concave surface and the convex surface on the valve surface is a second direction perpendicular to the first direction (the second direction is parallel to the radial direction of the valve body).

[0385] It should be noted that the cutout can be a strip-shaped cutout, the extension direction of the cutout is perpendicular to or parallel to the first direction, or the included angle between the extension direction of the cutout and the first direction is an acute angle, and it should be noted that the length of the cutout in the extension direction is less than the length of the recess 362, so that the cutout is completely located in the corresponding recess 362.

[0386] Optionally, at least part of the concave bottom surface 366 is a concave surface and a convex surface arranged staggered in the first direction, in a wave shape structure.

[0387] For example, the concave surface can be curved, such as a U-shaped cross-section, or can include an inclined surface, such as a V-shaped cross-section, but is not limited thereto. For example, the convex surface can be curved, such as an n-shaped cross-section, or can include an inclined surface, such as an inverted V-shaped cross-section.

[0388] Optionally, the cutout extends from the surface of the valve surface to the interior of the valve body perpendicularly along the axial direction of the valve body, or the cutout extends from the surface of the valve surface to the interior of the valve body obliquely relative to the axial direction of the valve body.

[0389] In the first direction, the valve surface has a center line 2001, and the cutout can be obliquely arranged relative to an axial cross-section passing through the center line 2001. A cross-section perpendicular to the axial cross-section is a radial cross-section, and the cutout can be obliquely arranged relative to the radial cross-section. Preferably, the cutout is obliquely arranged relative to the axial direction of the valve body 360, which can more effectively avoid the problem of fluid overflow.

[0390] Referring to FIG. 43, for example, the included angle a between the cutout and the axial direction of the valve body 360 can be 5-80 degrees, and in some embodiments, the included angle a between the cutout and the axial direction of the valve body 360 is 10-60 degrees, but is not limited thereto.

[0391] It should be noted that the included angle a between the cutout and the axial direction of the valve body 360 is due to the oblique arrangement of the cutout from the surface of the valve surface to the interior of the valve body relative to the axial direction of the valve body 360.

[0392] When a one-way valve with a single flow channel is used to transport fluid, different types of fluid residues remain on the wall surface of the flow channel during transportation, which can easily cause mixing or mutual contamination of different types of fluid. To solve this problem, in the embodiments of the present embodiment, at least one partition wall 367 is arranged in the valve body, which divides the flow channel into at least two independent sub-flow channels, and at least two cutouts corresponding to the at least two sub-flow channels are arranged on the valve surface. FIGS. 41-44 are schematic diagrams of a flow channel including two sub-flow channels (i.e., a double sub-flow channel), and FIGS. 45-48 are schematic diagrams of a flow channel including three sub-flow channels. Different sub-flow channels can transport different fluids, which can avoid the problem of mixing or mutual contamination of different fluid residues when transporting different fluids; different sub-flow channels can also transport the same fluid, which can increase the amount of fluid transported and shorten the transportation time when transporting the same fluid at the same time.

[0393] It should be noted that the fluid can be toothpaste, skin care products, etc., which is determined according to the actual scene.

[0394] For example, the at least partial cutout extends perpendicularly from the surface of the valve face to the interior of the valve body along the axial direction of the valve body, or the at least partial cutout extends obliquely to the interior of the valve body relative to the axial direction of the valve body.

[0395] Referring to FIGS. 41-44, optionally, the at least two sub-flow channels include a first sub-flow channel 3631 and a second sub-flow channel 3632, and the valve face is provided with a first cutout 371a corresponding to the first sub-flow channel 3631 and a second cutout 371b corresponding to the second sub-flow channel 3632;

[0396] The valve face is provided with a center line 2001 extending in a direction perpendicular to the first direction, the first cutout 371a and the second cutout 371b are respectively arranged on both sides of the center line 2001, and the first cutout 371a and the second cutout 371b are both arranged obliquely relative to the axial direction of the valve body, or the first cutout 371a and the second cutout 371b can both be arranged perpendicularly along the axial direction of the valve body, or one of the first cutout 371a and the second cutout 371b is arranged obliquely relative to the axial direction of the valve body, and the other of the first cutout 371a and the second cutout 371b is arranged perpendicularly along the axial direction of the valve body.

[0397] In some embodiments, the first cutout 371a and the second cutout 371b are both arranged obliquely relative to the axial direction of the valve body 360, at this time, the oblique directions of the first cutout 371a and the second cutout 371b can be the same or opposite, preferably, the oblique directions of the first cutout 371a and the second cutout 371b are opposite, which is more conducive to the independent arrangement of the corresponding first sub-flow channel 3631 and the second sub-flow channel 3632.

[0398] Optionally, the first cutout 371a and the second cutout 371b are symmetrically arranged on both sides of the center line 2001.

[0399] It should be noted that the positions of the first cutout 371a and the second cutout 371b are not limited to the above, for example, one of the first cutout 371a and the second cutout 371b can be arranged on the center line 2001.

[0400] In some specific embodiments, in the first direction, the concave bottom surface 366 includes a first region and a second region, the first region and the second region are symmetrically arranged relative to the center line 2001, the first cutout 371a is arranged in the first region, and the second cutout 371b is arranged in the second region. The first region can be at least one of a concave surface, a convex surface, a flat surface, or an inclined surface. The second region can be at least one of a concave surface, a convex surface, a flat surface, or an inclined surface. The shapes of the first region and the second region can be the same or different.

[0401] Referring to FIGS. 45-48, optionally, the at least two sub-flow passages include a third sub-flow passage 3633, a fourth sub-flow passage 3634, and a fifth sub-flow passage 3635 arranged in sequence in a first direction, and the valve face is provided with a third cutout 371c corresponding to the third sub-flow passage 3633, a fourth cutout 371d corresponding to the fourth sub-flow passage 3634, and a fifth cutout 371e corresponding to the fifth sub-flow passage 3635; in the first direction, the third cutout 371c, the fourth cutout 371d, and the fifth cutout 371e are arranged at intervals.

[0402] It should be noted that the arrangement of the third sub-flow passage 3633, the fourth sub-flow passage 3634, and the fifth sub-flow passage 3635 can be set according to actual needs, and is not limited to the above.

[0403] Optionally, the fourth cutout 371d is located on the center line 2001, and the third cutout 371c and the fifth cutout 371e are symmetrically arranged on both sides of the center line 2001.

[0405] Optionally, the fourth cutout 371d is located on the center line 2001, and the third cutout 371c and the fifth cutout 371e are symmetrically arranged on both sides of the center line 2001.

[0406] Optionally, the fourth cutout 371d is located on the center line 2001, and the third cutout 371c and the fifth cutout 371e are symmetrically arranged on both sides of the center line 2001.

[0407] In some specific embodiments, in the first direction, the concave bottom surface 366 includes a third region, a fourth region, and a fifth region, the third cutout 371c is arranged on the third region, the fourth cutout 371d is arranged on the fourth region, and the fifth cutout 371e is arranged on the fifth region. The third region can be at least one of a concave surface, a convex surface, a flat surface, and an inclined surface, the fourth region can be at least one of a concave surface, a convex surface, a flat surface, and an inclined surface, and the fifth region can be at least one of a concave surface, a convex surface, a flat surface, and an inclined surface. The shapes of the third region, the fourth region, and the fifth region can be the same or different.

[0408] It should be noted that Fig. 49 shows a fluid flow direction diagram in which one cutout corresponds to one sub-flow passage, the dashed arrows in Fig. 49 represent the fluid flow direction, and Fig. 49 shows a structure in which two sub-flow passages are provided. The fluid of the first sub-flow passage 3631 flows out from the first cutout 371a, and the fluid of the second sub-flow passage 3632 flows out from the second cutout 371b. However, the correspondence between the cutouts and the sub-flow passages in the present embodiment is not limited to the above. For example, at least one partition wall 367 is provided inside the valve body 360, the partition wall 367 divides the flow passage into at least two sub-flow passages, at least one cutout is provided on the valve face, and the sixth cutout 206 is included in the at least one cutout and is provided in corresponding communication with the at least two sub-flow passages.

[0409] Optionally, a through hole 3011 is provided on the partition wall 367 between the two adjacent sub-flow passages, and the through hole 3011 is configured to be provided through the partition wall 367 to communicate the two adjacent sub-flow passages.

[0410] Specifically, referring to Fig. 50, Fig. 50 shows a fluid flow direction diagram in which one cutout corresponds to and communicates two sub-flow passages, and the dashed arrows in Fig. 50 represent the fluid flow direction. The at least two sub-flow passages include a sixth sub-flow passage 3636 and a seventh sub-flow passage 3637, the sixth sub-flow passage 3636 and the seventh sub-flow passage 3637 are communicated through the through hole 3011 to share one cutout, i.e., the sixth cutout 206, the through hole 3011 is provided on the partition wall 367 between the sixth sub-flow passage 3636 and the seventh sub-flow passage 3637, the fluid of the sixth sub-flow passage 3636 enters the seventh sub-flow passage 3637 through the through hole 3011 and then flows out from the sixth cutout 206, and the fluid in the seventh sub-flow passage 3637 directly flows out from the sixth cutout 206.

[0411] It should be noted that Fig. 50 shows a fluid flow direction diagram in which one cutout corresponds to and communicates two sub-flow passages, but in an embodiment in which one cutout corresponds to and communicates multiple sub-flow passages, the number of sub-flow passages corresponding to one cutout is not limited to two.

[0412] It should be noted that in an embodiment in which one cutout corresponds to and communicates multiple sub-flow passages and at least two cutouts are provided on the valve face, the number of sub-flow passages corresponding to the at least two cutouts can be the same or different.

[0413] It should be noted that in an embodiment in which one cutout corresponds to and communicates multiple sub-flow passages and at least two cutouts are provided on the valve face, the sub-flow passages corresponding to the same cutout are in communication with each other, and the sub-flow passages corresponding to different cutouts are independent of each other (i.e., not in communication).

[0414] It should be noted that in one valve body 360, only one cutout can correspond to one sub-flow passage, or only one cutout can correspond to at least two sub-flow passages, or both of the above structures can be included, i.e., part of the cutouts correspond to one-to-one sub-flow passages, and the other part of the cutouts correspond to one cutout corresponding to at least two sub-flow passages.

[0415] It should be noted that the valve body can be a cylinder or a cuboid structure, which is not limited here.

[0416] The toothbrush provided by the embodiment of the present application also includes a handle and a toothbrush head, the toothbrush head includes a brush handle and a brush plate, the brush plate is provided with bristles, the brush plate is provided with a third one-way valve 36, the handle is provided with a containing cavity for containing toothpaste, the toothbrush head is provided with a channel for communicating with the containing cavity, and the third one-way valve 36 communicates with the channel.

[0417] For example, the height of the third one-way valve 36 is lower than the height of the bristles, so as not to affect the normal use of the bristles. For example, since the third one-way valve 36 is made of flexible material, the third one-way valve 36 can be reused as the bristles. For example, the third one-way valve 36 is made of flexible material as a whole, such as soft glue or silica gel, which is beneficial to protect the gums.

[0418] For example, the brush plate is in a strip structure, the third one-way valve 36 includes a valve body 360, one end of the valve body 360 is provided with a toothpaste inlet, the other end of the valve body 360 is provided with a valve surface, the valve surface is provided with a recessed part 362, the recessed part 362 is provided with a cutout, the cutout can be in a strip structure, and the length extension direction of the cutout is parallel to the length extension direction of the long side of the brush plate.

[0419] The toothpaste extrudes the cutout of the one-way valve and opens the cutout, and flows out to the toothbrush head, the recessed part 362 constitutes a buffer space for the toothpaste, so as to avoid the toothpaste overflowing directly after flowing out of the cutout, thereby causing material waste. When the toothbrushing mode is closed, the one-way valve is made of flexible material, the cutout is automatically closed, and the function of preventing the toothpaste from flowing back is achieved.

[0420] In combination with FIG. 39, in the first direction (i.e., the short side direction of the toothbrush head), the valve surface includes two first convex parts 363 which are arranged at intervals, the recessed part 362 is formed between the two first convex parts 363, and the two first convex parts 363 play a role in blocking the toothpaste from flowing out in the first direction, so as to avoid the toothpaste overflowing due to insufficient space in the short side direction of the brush plate.

[0421] For example, the bristles also include soft bristles and hard bristles. For example, the soft bristles and the one-way valve are integrally injection molded, which is beneficial to the installation of the third one-way valve 36 and enhances the installation stability of the third one-way valve 36.

[0422] Exemplarily, the third one-way valve 36 is arranged close to the brush handle in the direction from the handle to the brush head, i.e. the extending direction of the long side of the brush plate, and a blocking portion is arranged on the side of the third one-way valve 36 close to the brush handle, the blocking portion is arc-shaped, and the orthographic projection of the third one-way valve 36 on the blocking portion is located on the blocking portion, so as to block the toothpaste flowing out of the third one-way valve 36 from moving in the direction close to the brush handle.

[0423] Exemplarily, the material of the blocking portion is flexible, and the blocking portion can be made of the same material as the third one-way valve 36, for example, soft glue or silica gel. Exemplarily, the blocking portion can be reused as a bristle.

[0424] Exemplarily, the valve body 360 of the one-way valve includes a first portion and a second portion in the axial direction thereof, the first portion is embedded in the brush plate, the second portion is exposed to the brush plate, the valve face is located at one end of the second portion away from the first portion, and the second portion is located on the same side of the brush plate as the toothbrush bristles.

[0425] Exemplarily, the radial cross-sectional area of the second portion is less than or equal to the radial cross-sectional area of the first portion, but it is not limited thereto.
