[0016] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0017] The terms "first", "second", etc. 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 interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0018] In the following, in conjunction with the accompanying drawings, a rotating shaft, a motor and an automatic discharging device provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0019] See also Figure 1-3 , Figure 1-3 A rotating shaft provided in an embodiment of the present application is applied to a motor, and the rotating shaft comprises: a rotating shaft body 100, wherein the rotating shaft body 100 comprises a first segment 140, and at least one side of the first segment 140 corresponding to the coil winding of the motor is set to be a plane.

[0020] It can be understood that when one of the surfaces of the first segment 140 corresponding to the winding is set as a plane, the cross-sectional shape of the first segment 140 is similar to a "D" shape, and when both surfaces of the first segment 140 corresponding to the winding are set as planes, the cross-sectional shape of the first segment 140 is similar to a quadrilateral with arc-shaped upper and lower sides.

[0021] Specifically, see Figure 4The motor may include a rotor support 200 corresponding to the first segment 140, wherein the rotor support 200 may be sleeved on the first segment 140, and the coil winding of the motor may be wound around the rotor support 200. Figure 6 The rotor support 200 may be provided with a connection hole 210 corresponding to the first segment 140 , the first segment 140 may be passed through the connection hole 210 , and the cross-sectional shape of the connection hole 210 may be the same as the cross-sectional shape of the first segment 140 .

[0022] See also Figure 8 In the related art, the portion of the shaft body 100 corresponding to the coil winding of the motor is usually cylindrical, and accordingly, the cross-sectional shape of the connecting hole of the rotor bracket is also cylindrical. The cross-sectional shape of the rotor bracket can be specifically referred to Figure 8 The shape indicated by the dotted circle in FIG. 1 is shown. At this time, the sum of the sizes of the winding spaces that can be provided on the left and right sides of the rotor support is: 2*L1. In some embodiments of the present application, when the cross-sectional shape of the first segment 140 is similar to a "D" shape, the cross-sectional shape of the connecting hole 210 can also be a "D" shape. For example, see Figure 8 When the left side of the rotor bracket is set as a plane, the size of the winding space on the left side of the rotor bracket will increase to L2, and the size of the winding space on the right side of the rotor bracket remains L1. Compared with the rotor bracket in the related art, the winding space of the rotor bracket in this embodiment can be increased (L2-L1), wherein L2 is larger than L1.

[0023] Correspondingly, in other embodiments of the present application, when the cross-sectional shape of the first segment 140 is similar to a quadrilateral with arc-shaped upper and lower sides, the cross-sectional shape of the connecting hole 210 may also be a quadrilateral with arc-shaped upper and lower sides, for example, see Figure 8 When both the left and right sides of the rotor bracket are planes, the size of the winding space on the left side of the rotor bracket will increase to L2, and the size of the winding space on the right side of the rotor bracket will also increase to L2. Compared with the rotor bracket in the related art, the winding space of the rotor bracket in this embodiment can be increased by 2*(L2-L1), which is beneficial to increase the number of coil winding turns and improve the motor performance without changing the volume of the motor.

[0024] Optionally, in this specific embodiment, if Figures 1 to 4 As shown, the two surfaces of the first segment 140 corresponding to the winding are both set as planes; that is, the outer side wall of the first segment 140 is provided with a first plane 141 and a second plane 142, and the first plane 141 is opposite to the second plane 142, that is, the first segment 140 is a flat tube.

[0025] It can be understood that the rotating shaft is applied to the motor. When used in the motor, the rotating shaft is connected to the rotor bracket 200 of the motor. The rotor bracket 200 needs to be provided with corresponding connecting holes 210 to install the rotating shaft, and space for the coil winding needs to be reserved. That is to say, the shape and size of the connecting hole 210 will affect the size of the coil winding space.

[0026] In other words, when the rotating shaft is the rotating shaft of a motor, the cross-sectional shape of the first segment 140 matches the cross-sectional shape of the connecting hole 210 of the rotor support 200 in the motor, and the first segment 140 is used to connect to the rotor support 200 .

[0027] The cross-sectional shape of the first segment 140 matches the cross-sectional shape of the connecting hole 210 of the rotor support 200 in the motor, which may mean that the cross-sectional shape of the first segment 140 is the same as the cross-sectional shape of the connecting hole 210 , and the cross-sectional size of the first segment 140 may be the same as the cross-sectional size of the connecting hole 210 of the rotor support 200 .

[0028] Therefore, in order to allow the rotor bracket 200 to reserve more space for coil winding, the present application sets at least one side of the shaft corresponding to the winding to be a plane, so as to reduce the space occupied by the shaft on the winding bracket, that is, the size of the connecting hole 210 can also be reduced, and the coil winding space is increased, which is conducive to increasing the number of coil winding turns and improving the motor performance (such as the swing and torque of the motor). Through the method of the present application, the motor performance can be improved without increasing the overall volume of the motor, which is conducive to taking into account the miniaturization design and high performance of the motor.

[0029] In addition, there are some automatic discharging devices on the market, such as electric toothbrushes that automatically discharge toothpaste or skin care devices that automatically discharge skin care products. In order to realize the automatic discharging function of products such as electric toothbrushes or skin care devices, it is usually necessary to add a consumable input device and a transmission pipeline connecting the consumable input device and the output head in the electric toothbrush or skin care device. This will usually result in a large volume of the automatic discharging device, which is not conducive to the miniaturization design of the automatic discharging device.

[0030] Based on this, the present application further configures the rotating shaft as a hollow structure and forms a flow channel inside the rotating shaft. In this way, when the rotating shaft is applied to an automatic discharging device, the consumables can be transmitted through the internal flow channel of the rotating shaft, that is, the internal space of the rotating shaft can be reused. Therefore, setting the flow channel does not require additional space inside the automatic discharging device, which is conducive to the miniaturized design of the automatic discharging device.

[0031] That is to say, while taking into account the miniaturized design and high performance of the motor, the present application can also utilize the hollow shaft of the motor as a consumable flow channel, which is conducive to the miniaturized and lightweight design of the automatic discharging device.

[0032] Specifically, in the embodiment of the present application, a flow channel 110 for transmitting consumables is provided inside the rotating shaft body 100 of the rotating shaft;

[0033] The input end of the flow channel 110 is located at the first end surface 120 of the shaft body 100 , and the output end of the flow channel 110 is located at the second end surface 130 of the shaft body 100 .

[0034] The rotating shaft can be used as the rotating shaft of the internal motor of various automatic discharging devices, wherein the automatic discharging device can be an electric toothbrush that automatically discharges toothpaste or a skin care device that automatically outputs skin care products.

[0035] Specifically, the consumables output device inside the automatic discharging device can be connected to the input end of the flow channel 110, for example, the output end of the peristaltic pump inside the automatic discharging device can be connected to the input end of the flow channel 110 through a hose. At the same time, the output end of the flow channel 110 can be connected to the output head of the automatic discharging device, specifically, the output end of the flow channel 110 can be connected to the consumables input end of the output head. In this way, on the one hand, the motor inside the automatic discharging device can drive the output head through the shaft body 100, and on the other hand, the consumables output device inside the automatic discharging device can provide consumables to the output head through the flow channel 110 inside the shaft body 100 to achieve automatic discharging.

[0036] Among them, the output head can be a brush head of an electric toothbrush, a care head of various care equipment, a massage head, etc. The consumables can be toothpaste, mouthwash, oral care liquid, facial cleanser, cleaning liquid, various skin care products, etc.

[0037] The extension direction of the flow channel 110 may be parallel to the axial direction of the shaft body 100. The cross-sectional shape of the flow channel 110 may be set according to actual needs. In addition, the number of the flow channel 110 may be one, or the number of the flow channel 110 may be greater than one. When the number of the flow channel 110 is greater than one, a partition may be provided inside the shaft body 100, and the partition separates the internal space of the shaft body 100 to form at least two flow channels 110. The cross-sectional shape of the flow channel 110 may be circular, elliptical, polygonal, irregular, etc. Moreover, the flow channel 110 may be a straight pipe, a curved pipe, a spiral pipe or an irregular pipe, which is not limited in the present application.

[0038] The above-mentioned rotating shaft body can be a flat tube in its entirety, or a part of it can be a flat tube and the other part can be a round tube.

[0039] The partition may be formed integrally with the shaft body 100 . In addition, the partition may be formed by embedding a detachable partition into the shaft body 100 .

[0040] In this embodiment, the rotating shaft is set as a hollow structure and a flow channel 110 is formed inside the rotating shaft. In this way, when the rotating shaft is applied to an automatic discharging device, the consumables can be transmitted through the internal flow channel 110 of the rotating shaft, that is, the internal space of the rotating shaft can be reused. Therefore, the flow channel 110 does not need to occupy additional space inside the automatic discharging device, which is conducive to the miniaturization and lightweight design of the automatic discharging device.

[0041] See also Figure 4-7 , is a structural schematic diagram of a motor provided in an embodiment of the present application, wherein the motor includes a rotating shaft in the above embodiment, a rotor group mounted on the rotating shaft, and a stator assembly spaced apart from the rotor group.

[0042] The rotor assembly includes a rotor support 200 and a coil 300 wound on the rotor support 200. The rotor support 200 is formed by stacking a plurality of steel sheets 900. Figure 6 , is a schematic diagram of the structure of the rotor support 200 formed by stacking a plurality of steel sheets 900 in a direction perpendicular to the paper surface. It can be understood that the structures of the steel sheets 900 are the same. Figure 6 It may also be a schematic diagram representing the structure of one of the steel sheets 900 .

[0043] Among them, see Figure 6 , the rotor support 200 comprises:

[0044] The connecting portion 220 has a cross-sectional shape that matches the cross-sectional shape of the first segment 140, and the connecting portion 220 is provided with a connecting hole 210 corresponding to the first segment 140, and the first segment 140 is penetrated in the connecting hole 210, so that the rotating shaft can be driven to rotate synchronously during the rotation of the rotor assembly.

[0045] The rotor bracket 200 also includes a first connecting arm 230 and a second connecting arm 250 respectively connected to the two sides of the connecting portion 220; a first limiting portion 240 connected to the first connecting arm 230; and a second limiting portion 260 connected to the second connecting arm 250, wherein the two ends of the first connecting arm 230 are respectively connected to the connecting portion 220 and the first limiting portion 240; and the two ends of the second connecting arm 250 are respectively connected to the connecting portion 220 and the second limiting portion 260.

[0046] Specifically, the connecting portion 220 includes a first outer wall 221 and a second outer wall 222 facing each other, the first outer wall 221 is the outer wall of the connecting portion 220 facing away from the first plane 141, the second outer wall 222 is the outer wall of the connecting portion 220 facing away from the second plane 142, and the first outer wall 221 and the second outer wall 222 are respectively planar outer walls, the first limiting portion 240 is connected to the first outer wall 221 through the first connecting arm 230, and the first limiting portion 240 is arranged opposite to the first outer wall 221, and the first limiting portion 240 and the first outer wall 221 form a first winding space; the second limiting portion 260 is connected to the second outer wall 222 through the second connecting arm 250, and the second limiting portion 260 is arranged opposite to the second outer wall 222, and the second limiting portion 260 and the second outer wall 222 form a second winding space.

[0047] It is understandable that when the structure and shape of the first segment 140 of the shaft changes, the shape of the connecting portion 220 also changes accordingly, and thus the sizes of the first winding space and the second winding space also change accordingly. Thus, by setting at least one side of the first segment 140 of the shaft corresponding to the winding space as a plane, the size of the corresponding winding space can be increased, which is conducive to increasing the number of coil winding turns and improving the motor performance.

[0048] In this specific embodiment, the cross-sectional shape of the connecting portion 220 may be the same as the cross-sectional shape of the first segment 140 , and the size of the outer contour of the cross-sectional shape of the connecting portion 220 is larger than the cross-sectional size of the first segment 140 .

[0049] Optionally, the steel sheet may be a silicon steel sheet or a silicon steel sheet.

[0050] See also Figure 6 , Figure 6 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 winding space, and the length of the second connecting arm 250 forms the length of the second winding space. Hereinafter, the length of the first connecting arm 230 and the length of the second connecting arm 250 are both referred to as the length of the winding space L. 绕线空间 .

[0051] like Figure 6 As shown, the total length of the steel sheet 900 (i.e., the length between the first limiting portion 240 and the second limiting portion 260) is L 总长 The dimension 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 lengths of the first winding space and the second winding space are both L 绕线空间 ; then L绕线空间 =(L 总长 -L 穿槽 ) / 2.

[0052] L 穿槽 The installation dimension L of the shaft 转轴 When the rotating shaft is a round tube, the length of the connecting hole 210 in the steel sheet 900 is L 穿槽 The L axis is equal to the axis of rotation. At this time, L 绕线空间 =(L 总长 -L 转轴 ) / 2.

[0053] For example, the shaft of the motor in the prior art is a round tube, and the outer diameter of the shaft is 3 mm, and the total length of the steel sheet 900 is 10 mm. 绕线空间 =(10-3) / 2=3.5 mm. In the embodiment of the present application, by setting one surface of the first segment 140 of the shaft as a plane, the outer diameter L of the shaft 转轴 can be reduced from 3mm to 2mm, then L 绕线空间 =(10-2) / 2=4mm, that is, the winding space on both sides of the rotor bracket 200 is increased by 0.5mm, thereby increasing the number of coil winding turns and thus improving the motor performance.

[0054] Although it is also possible to ensure that the winding space remains at 4 mm by using a larger steel sheet 900, for example, by using an 11 mm long steel sheet 900, this will require increasing the overall volume of the motor, which is not conducive to the miniaturized design of the motor.

[0055] Based on this, in the embodiment of the present application, the space of the motor in the longitudinal direction is utilized, and the first segment 140 of the rotating shaft is changed into a flat tube form, even if the outer side wall of the first segment 140 is provided with a first plane 141 and a second plane 142, the first plane 141 and the second plane 142 are opposite to each other, and the distance between the first plane 141 and the second plane 142 is less than the diameter of the rotating shaft body 100. Figure 2 As shown, the embodiment of the present application sets the first segment 140 to be a flat tube shape, which can reduce the installation space occupied by the shaft and increase the coil winding space, which is beneficial to improving the motor performance without changing the volume of the motor.

[0056] The stator assembly includes a stator bracket 400 and a permanent magnet 500 mounted on the stator bracket 400. It should be noted that the coil 300 of the rotor assembly can also be wound on the stator assembly, and the permanent magnet 500 can be arranged on the rotor assembly, which is not limited in the present application.

[0057] Please see further Figure 4The motor further comprises a housing, the housing comprising a front cover 600 and a rear cover 700 connected to the front cover 600. The two ends of the rotating shaft pass through the housing. The motor further comprises two bearings 800 respectively arranged at the two ends of the rotating shaft, one of the bearings 800 is embedded in the shaft hole of the front cover 600, and the other bearing 800 is embedded in the shaft hole of the rear cover 700. The rotating shaft passes through the two shaft holes respectively and is connected to the two bearings 800.

[0058] Optionally, the shaft body 100 further includes a second segment 150 connected to the first segment 140, the first end surface 120 is located at one end of the first segment 140 away from the second segment 150, and the second end surface 130 is located at one end of the second segment 150 away from the first segment 140;

[0059] The outer side wall of the second segment 150 is provided with a first groove 151 for engaging with an external component of the automatic discharging device.

[0060] The cross-sectional shape of the second segment 150 may be circular or flat.

[0061] The external element may be an output component of various automatic discharging devices. For example, when the automatic discharging device is an electric toothbrush, the external element may be a brush head of the electric toothbrush. For another example, when the automatic discharging device is a skin care device, the external element may be an output head of the skin care device.

[0062] It can be understood that when the rotating shaft is applied to an automatic discharging device, the connecting head 154 of the rotating shaft body 100 can be inserted into the card slot of the external element, and the external element can be engaged with the first groove 151 of the rotating shaft body 100 to realize the connection between the external element and the rotating shaft body 100, so that the rotating shaft body 100 drives the external element to operate.

[0063] Optionally, the outer side wall of the second segment 150 is further provided with a second groove 152 for connecting a waterproof gasket, and the second groove 152 is located on a side of the first groove 151 away from the second end surface 130 .

[0064] The automatic discharging device may further include a waterproof gasket, which may be embedded in the second groove 152, and the outer wall of the waterproof gasket may extend to the outer wall of the shell of the automatic discharging device to prevent water at the output head from passing through the waterproof gasket into the rear end and affecting the electrical components located at the rear end.

[0065] Optionally, a connecting head 154 of the shaft body 100 is formed between the first groove 151 and the second end surface 130 , and an outer side wall of the connecting head 154 is provided with an anti-foolproof plane 153 .

[0066] It can be understood that the inner wall of the above-mentioned slot of the output head can be provided with a plane matching the anti-fool plane 153. When the connecting head 154 is inserted into the slot, the anti-fool plane 153 fits with the plane of the inner wall of the slot. In this way, relative rotation between the connecting head 154 and the output head can be avoided, thereby improving the stability of the automatic discharging device.

[0067] Optionally, a one-way valve is provided in the flow channel 110 , and an output end of the one-way valve faces an output end of the corresponding flow channel 110 .

[0068] Among them, the one-way valve can be various types of one-way valves in the related technology. For example, in some embodiments of the present application, the one-way valve can be a duckbill valve, a silicone one-way valve, a Tesla valve, etc.

[0069] It is understandable that the consumables can only flow from the input end to the output end of the flow channel 110 , and cannot flow back from the output end to the input end of the flow channel 110 .

[0070] In this embodiment, a one-way valve is provided in the flow channel 110 , so that the problem of backflow of consumables in the flow channel 110 can be avoided.

[0079] The connecting portion 220 includes a first outer wall 221 and a second outer wall 222 facing each other, wherein the first outer wall 221 is the outer wall of the connecting portion 220 facing away from the first plane 141, and the second outer wall 222 is the outer wall of the connecting portion 220 facing away from the second plane 142, and the first outer wall 221 and the second outer wall 222 are respectively planar outer walls, the first limiting portion 240 is connected to the first outer wall 221 through the first connecting arm 230, and the first limiting portion 240 is arranged opposite to the first outer wall 221, and the first limiting portion 240 and the first outer wall 221 form a first winding space; the second limiting portion 260 is connected to the second outer wall 222 through the second connecting arm 250, and the second limiting portion 260 is arranged opposite to the second outer wall 222, and the second limiting portion 260 and the second outer wall 222 form a second winding space.

[0080] In this embodiment, by improving the structure of the rotating shaft body 100 and the rotor bracket 200, it is possible to take into account both the miniaturized design and high performance of the motor. At the same time, by setting the rotating shaft as a hollow structure, the space of the motor can be reasonably utilized to transmit consumables, which is conducive to the miniaturization and lightweight design of the automatic discharging device.

[0081] Optionally, the connecting portion 220 also includes a third outer wall 223 and a fourth outer wall 224 opposite to each other, the third outer wall 223 and the fourth outer wall 224 are located between the first outer wall 221 and the second outer wall 222, the third outer wall 223 connects the first outer wall 221 and the second outer wall 222, and the fourth outer wall 224 connects the first outer wall 221 and the second outer wall 222, and the third outer wall 223 and the fourth outer wall 224 correspond to the same circumference.

[0082] The third outer wall 223 and the fourth outer wall 224 corresponding to the same circumference may mean that the projections of the third outer wall 223 and the fourth outer wall 224 along the axis direction of the shaft body 100 are located on the same circumference. Specifically, the third outer wall 223 and the fourth outer wall 224 are partial areas of the outer side wall of the cylinder corresponding to the shaft body 100.

[0083] In this embodiment, by making the third outer wall 223 and the fourth outer wall 224 correspond to the same circumference, it is helpful to increase the cross-sectional area of ​​the first segment 140 and further increase the cross-sectional size of the flow channel 110 .
