In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and 2, a first embodiment of the present invention provides an electric toothbrush 1, the electric toothbrush 1 includes a toothbrush main body 11 and a toothbrush head 12 disposed on the toothbrush main body 11, the toothbrush main body 11 includes a driving member 112, an output shaft 1121 of the driving member 112 reciprocates in an axial direction, the toothbrush head 12 includes a linkage member 121 and a brush disc 122, opposite ends of the linkage member 121 are respectively connected to at least one side of the output shaft 1121 and the brush disc 122, the output shaft 1121 moves and drives the linkage member 121 to reciprocate in the axial direction, and the linkage member 121 drives the brush disc 122 to rotate in a reciprocating manner. It should be understood that the axial direction refers to a direction parallel to the central axis of the output shaft 1121.

It can be understood that, the output shaft 1121 drives the linkage member 121 to perform axial reciprocating motion so as to drive the brush disc 122 to perform reciprocating rotation, so that a structure for changing the driving force direction is not required to be arranged between the toothbrush main body 11 and the linkage member 121, noise and vibration of the electric toothbrush 1 are greatly reduced, and meanwhile, the cleaning effect of the electric toothbrush 1 can be ensured by the reciprocating rotation of the brush disc 122. In addition, the output shaft 1121 drives the linkage member 121 to reciprocate axially, so that the rotation of the brush disc 122 can be realized without additionally arranging a driving member in the toothbrush head 12, thereby improving the simplicity of the electric toothbrush 1. In addition, the driving member 112 does not need to be additionally arranged in the toothbrush head 12, so that the vibration and noise of the electric toothbrush 1 are further reduced, and the use experience of the electric toothbrush 1 is greatly improved.

Further, the toothbrush main body 11 is detachably connected to the toothbrush head 12.

Understandably, through the design that the toothbrush main body 11 is detachably connected with the toothbrush heads 12, one toothbrush main body 11 can correspond to a plurality of toothbrush heads 12, so that the toothbrush heads 12 can be replaced by new toothbrush heads 12 when the toothbrush heads 12 are damaged or old, the service life of the electric toothbrush 1 is further ensured, and meanwhile, the toothbrush main body 11 can be continuously used, and the waste of resources is also avoided. Optionally, the connection mode of the toothbrush head 12 and the toothbrush body 11 is not limited, and may be, but not limited to, one or more combinations of connection modes such as clamping, snap connection, abutting connection, threaded connection, or magnetic attraction connection.

The output shaft 1121 of the driving member 112 is in transmission connection with one end of the linking member 121 away from the brush disc 122, and the output shaft 1121 reciprocates along the axial direction to drive the linking member 121 to move in the same direction. It will be appreciated that the type of drive member 112 is not limited and may be, but is not limited to, a motor such as a voice coil motor or other type of motor that the output shaft 1121 is axially reciprocable.

It will be appreciated that by disposing the power source 113 inside the bottom case 111, the power source 113 can provide power to the driving member 112, and can prevent water or other liquid from contacting the power source 113 and causing danger or damage. In addition, through the design that the output shaft 1121 of the driving part 112 is directly connected with the end, away from the brush disc 122, of the linkage part 121 and drives the linkage part 121 to perform axial reciprocating motion, the driving part 112 and the linkage part 121 can move without other transmission elements, vibration and noise caused by the arrangement of other transmission elements are avoided, and the use experience of the electric toothbrush 1 is further improved. In addition, the design that the output shaft 1121 is directly connected with the linkage member 121 can greatly reduce the loss of the driving force of the output shaft 1121 in the transmission process, so that the cleaning strength of the electric toothbrush 1 is better.

Referring to fig. 1-3, further, a sealing cover 115 is further disposed at an end of the bottom housing 111 close to the toothbrush head 12, a through hole 1151 matching the output shaft 1121 is formed at a position of the sealing cover 115 corresponding to the output shaft 1121, and the output shaft 1121 is exposed out of the bottom housing 111 through the through hole 1151.

It can be understood that, through the design that the sealing cover 115 is arranged at one end of the bottom shell 111 close to the toothbrush head 12 and the through hole 1151 matched with the size of the output shaft 1121 is formed in the sealing cover 115, the problem that water or other foreign matters enter the toothbrush main body 11 to cause electric leakage or damage to the electric toothbrush 1 can be effectively prevented, so that the safety and the service life of the electric toothbrush 1 are further improved.

Further, the connection between the sealing cover 115 and the bottom case 111 is not limited, and may be a snap connection, a threaded connection, a magnetic connection, an integral molding, or a riveting connection. Specifically, in the embodiment of the present invention, the sealing cover 115 is screwed with the bottom case 111.

Further, one end of the bottom case 111 close to the toothbrush head 12 is provided with a protrusion 1111 and the protrusion 1111 is matched with the sealing cover 115, and one end of the sealing cover 115 close to the power source 113 is connected with the protrusion 1111 in a matching manner, optionally, the connection manner of the one end of the sealing cover 115 close to the power source 113 and the protrusion 1111 may be, but not limited to, clamping, threaded connection, magnetic connection, integral molding or riveting. Specifically, in the embodiment of the present invention, one end of the sealing cover 115 near the power source 113 is screwed with the protrusion 1111.

Further, a second connecting structure 114 is provided at one end of the toothbrush body 11 near the brush plate 122. Toothbrush head 12 still includes hollow epitheca 123 and first connection structure 125, and interlock spare 121 sets up in epitheca 123 at least partially, and first connection structure 125 sets up in epitheca 123 and is close to the one end of toothbrush main part 11, and first connection structure 125 sets up with second connection structure 114 relatively, and toothbrush main part 11 passes through first connection structure 125 with toothbrush head 12 and can dismantle with the cooperation of second connection structure 114 and be connected.

It can be understood that the first connecting structure 125 and the second connecting structure 114 are oppositely arranged, so that the toothbrush body 11 can be reliably connected with the toothbrush head 12, thereby ensuring that the toothbrush head 12 can rotate within a predictable range when a user holds the toothbrush body 11 during use, and achieving the effect of cleaning teeth as expected.

Optionally, the first connecting structure 125 and the second connecting structure 114 may be, but not limited to, a detachable connecting manner such as a snap connection, a threaded connection, or a magnetic attraction connection.

Specifically, in the embodiment of the present invention, the second connecting structure 114 is disposed at one end of the sealing cover 115 close to the brush plate 122, and the first connecting structure 125 is magnetically connected to the second connecting structure 114, that is, the toothbrush head 12 is detachably connected to the toothbrush main body 11 at least by magnetic attraction.

Further, the output shaft 1121 of the driving member 112 is in transmission connection with one end of the linking member 121 away from the brush tray 122, the first connecting structure 125 is a first annular magnetic component 1251, the second connecting structure 114 is a second magnetic component 1141 matched with the first connecting structure 125 in shape, and the output shaft 1121 and the second magnetic component 1141 are coaxially disposed.

It can be understood that, by setting the first connecting structure 125 as the annular first magnetic attraction piece 1251, the output shaft 1121 can be connected to the linking structure by passing through the first magnetic attraction piece 1251, thereby ensuring that when the first magnetic attraction piece 1251 and the second magnetic attraction piece 1141 are magnetically attracted, the output shaft 1121 is coaxial with the first magnetic attraction piece 1251 and the second magnetic attraction piece 1141, thereby reducing the possibility that the output shaft 1121 generates radial movement due to the uneven connection force around the output shaft 1121, and further reducing the vibration and noise of the electric toothbrush 1.

Further, the first magnetic component 1251 is disposed at an end of the inner wall of the upper housing 123 close to the toothbrush body 11, and the toothbrush head 12 and the toothbrush body 11 are detachably connected by the first magnetic component 1251 and the second magnetic component 1141.

It can be understood that, the design that the toothbrush main body 11 and the toothbrush head 12 are magnetically connected through the first magnetic element 1251 and the second magnetic element 1141, which can avoid the problem that the connection structure between the toothbrush main body 11 and the toothbrush head 12 is old and leads to loose connection, thereby ensuring the reliability of the connection between the toothbrush main body 11 and the toothbrush head 12.

Further, in the embodiment of the present invention, the toothbrush head 12 and the toothbrush body 11 are detachably connected by being engaged.

Referring to fig. 3 and 4, exemplary ways of engaging the toothbrush head 12 with the toothbrush body 11 may be as follows: the end of the linkage member 121 far away from the brush disc 122 is provided with a connecting sleeve 1213, the end of the output shaft 1121 close to the brush disc 122 is structurally matched with the connecting sleeve 1213 and is detachably embedded in the connecting sleeve 1213, and the output shaft 1121 drives the linkage member 121 to axially reciprocate through the connecting sleeve 1213.

It can be understood that the design that the output shaft 1121 is detachably embedded in the connecting sleeve 1213 ensures the firmness of the connection between the output shaft 1121 and the linkage member 121, and further reduces the vibration, noise and waste of driving force of the electric toothbrush 1.

Further, the linkage member 121 includes a connecting rod 1211 and a connecting sleeve 1213, one end of the connecting sleeve 1213 is fixedly connected to one end of the connecting rod 1211 away from the brush plate 122, and the other end of the connecting sleeve 1213 is provided with a limit groove 12131 corresponding to the output shaft 1121, the limit groove being matched with one end of the output shaft 1121 away from the power source 113 in size. One end of the output shaft 1121, which is far away from the power source 113, is embedded in the limiting groove 12131 and is clamped with the side wall of the limiting groove 12131, so that the connecting sleeve 1213 can be reliably driven to move in the same direction when the output shaft 1121 axially reciprocates, and the brush disc 122 is driven to rotate in a reciprocating manner by the movement of the linkage member 121.

Referring to fig. 4 and fig. 5, further, a first locking portion 11211 is disposed at an end of the output shaft 1121 away from the power source 113, a second locking portion 12132 having a size matched with that of the first locking portion 11211 is disposed on a side wall of the limiting groove 12131, and the first locking portion 11211 and the second locking portion 12132 are engaged with or separated from each other to achieve locking or unlocking of the output shaft 1121 and the linkage member 121.

Further, one of the first detent 11211 and the second detent 12132 is a detent protrusion 121321, and the other is a matching detent recess 112111. Specifically, in the embodiment of the present invention, the first latching portion 11211 is a latching recess 112111, and the second latching portion 12132 is a latching protrusion 121321 matching with the latching recess 112111. When the output shaft 1121 is connected to the linking member 121, the locking protrusion 121321 is locked with the locking recess 112111, so that the output shaft 1121 can drive the linking member 121 to move in the same direction through the cooperation of the locking protrusion 121321 and the locking recess 112111. Preferably, the shape of the retaining recess 112111 is the same as that of the output shaft 1121, that is, the retaining recess 112111 is formed along the circumferential direction of the output shaft 1121, so that any direction of the end of the output shaft 1121, which is close to the brush disc 122, can be connected with the retaining protrusion 121321 in a matching manner, and the convenience of connecting the toothbrush main body 11 and the toothbrush head 12 is further improved.

Further, a position yielding opening 12133 is formed in the side wall of the limiting groove 12131 corresponding to the position of the position locking protrusion 121321, so that the position locking recess 112111 can pass through the position corresponding to the position locking protrusion 121321 in the limiting groove 12131, thereby ensuring the smoothness of connecting or detaching the output shaft 1121 and the linkage member 121.

Further, the connecting sleeve 1213 has a larger cross-sectional size at an end thereof adjacent to the brush plate 122 than the cross-sectional size of the connecting rod 1211.

It should be understood that as a modified embodiment, the connection sleeve 1213 can also be disposed at an end of the output shaft 1121 close to the brush plate 122, and an end of the linking member 121 away from the brush plate 122 is structurally matched with the connection sleeve 1213 and detachably embedded in the connection sleeve 1213.

Referring to fig. 3 and 5, the toothbrush head 12 further includes a shock-absorbing structure disposed in the upper housing 123, and the shock-absorbing structure is disposed between the inner wall of the upper housing 123 and the linkage member 121 to reduce or prevent the shock or the waste of the transmission force generated by the radial movement of the linkage member 121. Alternatively, the shock-absorbing structure may be disposed separately from the linking member 121 or integrally formed therewith.

Further, the damping structure is a limiting member 124, the limiting member 124 is sleeved on the linking member 121, and the shape of the limiting member 124 is matched with that of the inner wall of the upper shell 123 to limit the linking member 121 to move radially.

It can be understood that, by sleeving the limiting member 124 matched with the inner wall of the upper shell 123 in shape on the linkage member 121, the linkage member 121 can be effectively prevented from moving radially in the upper shell 123, thereby further reducing noise and vibration of the electric toothbrush 1.

Further, one end of the stopper 124 away from the brush plate 122 abuts one end of the connection sleeve 1213 close to the brush plate 122, and one end of the stopper 124 close to the brush plate 122 abuts the inner wall of the upper case 123. It can be understood that the design that the opposite ends of the limiting member 124 respectively abut against the connecting sleeve 1213 and the inner wall of the upper housing 123 can effectively limit the limiting member 124 at the preset position in the upper housing 123, so as to prevent the limiting member 124 from moving radially in the upper housing 123 to generate vibration and noise, that is, further reduce the vibration and noise of the electric toothbrush 1.

Referring to fig. 4-6, further, the linking member 121 further includes an auxiliary structure 1212 disposed at an end of the connecting rod 1211 close to the brush plate 122, the brush plate 122 is provided with a driven structure 12211 engaged with the auxiliary structure 1212, the connecting rod 1211 moves and drives the driven structure 12211 to move through the auxiliary structure 1212, and the driven structure 12211 drives the brush plate 122 to rotate.

It can be understood that, by the design of the auxiliary structure 1212 on the connecting rod 1211 and the driven structure 12211 on the brush plate 122, when the linkage member 121 axially reciprocates, the linkage member 121 can drive the brush plate 122 to rotate in a direction consistent with the moving direction of the linkage member 121, so as to function to change the direction of the driving force of the driving member 112.

It should be understood that the specific matching manner of the auxiliary structure 1212 and the driven structure 12211 is not limited, as long as the auxiliary structure 1212 drives the driven structure 12211 to rotate when the connecting rod 1211 performs the axial reciprocating motion, so as to achieve the effect of rotating the brush plate 122.

Referring to fig. 5-7, further, the brush plate 122 includes a connecting member 1221 having a driven structure 12211 and a cleaning member 1222 for cleaning teeth, the connecting member 1221 is driven by the movement of the linkage member 121, and the connecting member 1221 rotates to drive the cleaning member 1222 to rotate coaxially.

Understandably, the design that the linkage part 121 drives the cleaning part 1222 to rotate coaxially avoids additional vibration and friction which may be caused by eccentric rotation, that is, vibration and noise of the electric toothbrush 1 are reduced, thereby further improving the practicability of the electric toothbrush 1.

With reference to fig. 5-7, as an exemplary first embodiment of the auxiliary structure 1212 and the driven structure 12211, the auxiliary structure 1212 may further be a first sliding block 12122 disposed on the connecting rod 1211, the driven structure 12211 is a second sliding block 122112 disposed on the brush plate 122, and the connecting rod 1211 movably drives the first sliding block 12122 to rotate so as to drive the second sliding block 122112 to rotate, so as to rotate the brush plate 122.

It can be understood that, by designing the auxiliary moving structure 1212 as the first sliding block 12122 and the driven structure 12211 as the second sliding block 122112 disposed on the brush plate 122, the connecting rod 1211 is able to rotate the first sliding block 12122 and further rotate the second sliding block 122112 to rotate the brush plate 122, so as to ensure that the brush plate 122 can rotate to achieve the function of cleaning teeth.

Furthermore, the first slider 12122 forms an included angle with the connecting rod 1211, the position of the connecting member 1221 on which the connecting hole is formed is defined as the second slider 122112, the first slider 12122 extends into the connecting hole so that the connecting rod 1211 can rotate in the same direction by the acting force generated by the first slider 12122 and the side wall of the connecting hole when moving axially, thereby driving the connecting member 1221 to rotate in the same direction, and further the connecting member 1221 drives the cleaning member 1222 to rotate in the same direction.

Further, a portion defining the connection between the connecting rod 1211 and the connecting sleeve 1213 is a first section 12111, a portion defining the connection between the connecting rod 1211 and the first slider 12122 is a second section 12112, and an included angle is formed between the first section 12111 and the second section 12112 in a natural state. When the auxiliary structure 1212 is the first slider 12122 and the driven structure 12211 is the second slider 122112, the angle between the first segment 12111 and the second segment 12112 changes.

As an embodiment, when the linking member 121 drives the connecting member 1221 to rotate, the joint of the first section 12111 and the second section 12112 generates elastic deformation, and the position of the limiting member 124 corresponding to the joint of the first section 12111 and the second section 12112 defines the deformation space 1241, and the first section 12111 and/or the second section 12112 can generate a certain degree of deformation in the deformation space 1241, so that the linking member 121 can drive the connecting member 1221 to rotate smoothly.

It can be understood that the connection between the first section 12111 and the second section 12112 can generate elastic deformation, so that the linkage 121 can play a certain buffering role, and prevent the connection 1221 from rotating too hard and irritating, thereby improving the uniformity of the rotation of the cleaning element 1222 and further improving the experience of the electric toothbrush 1.

As another example, the first segment 12111 is rotatably connected to the second segment 12112, and when the linkage 121 rotates the connection 1221, the second segment 12112 rotates relative to the first segment 12111 within a certain threshold. It can be understood that the design of the rotational connection between the first section 12111 and the second section 12112 enables the linkage 121 to play a certain buffering role, and prevents the connecting member 1221 from rotating too hard and irritating, thereby improving the uniformity of the rotation of the cleaning member 1222 and further improving the experience of the electric toothbrush 1.

Referring to fig. 8, as a second embodiment of the auxiliary structure 1212 and the driven structure 12211, for example, the auxiliary structure 1212 is disposed as a tooth slot 12121 opened on the connecting rod 1211, the driven structure 12211 is a gear 122111 engaged with the tooth slot 12121, and the linking member 121 cooperates with the gear 122111 via the tooth slot 12121 to drive the brush plate 122 to rotate.

It can be understood that the auxiliary driving structure 1212 is provided as the tooth grooves 12121 and the driven structure 12211 is provided as the gear 122111, so that the connecting rod 1211 can drive the brush plate 122 to rotate in the same direction when axially reciprocating, and the brush plate 122 of the electric toothbrush 1 can be rotated to clean teeth, thereby ensuring the practicability of the electric toothbrush 1.

Further, when the auxiliary structure 1212 is a tooth slot 12121 and the driven structure 12211 is provided as the gear 122111, the tooth slot 12121 is opened on the linking member 121 on one side of the gear 122111. Or, one side of the linkage member 121 close to the gear 122111 is substantially an arc-shaped surface, and the tooth slot 12121 is opened on the arc-shaped surface of the linkage member 121, and the arc-shaped surface is located at least on one side of the gear 122111. The gear 122111 has tooth slots 12121 on the linkage 121 at two opposite sides.

It can be understood that, one side of the gear 122111 is provided with the tooth slot 12121, which can realize the function that the tooth slot 12121 can drive the gear 122111 to rotate when reciprocating axially relative to the brush disc 122. One side of the linkage part 121 close to the gear 122111 is designed to be arc-shaped, so that the contact distance between the tooth slot 12121 and the gear 122111 can be increased, the rotation angle of the gear 122111 is further increased, and the cleaning force of the electric toothbrush 1 is further ensured. Tooth grooves 12121 are formed on two opposite sides of the gear 122111, so that the rotation force of the driving gear 122111 can be further improved, and the cleaning force of the electric toothbrush 1 can be further ensured.

Specifically, when secondary structure 1212 is teeth 12121 and driven structure 12211 is configured as gear 122111, gear 122111 is disposed on a side of connecting member 1221 facing away from cleaning elements 1222. That is, the output shaft 1121 drives the connecting rod 1211 to axially reciprocate through the connecting sleeve 1213, so as to drive the tooth slots 12121 to axially reciprocate, and then the tooth slots 12121 drive the gear 122111 to rotate in the same direction, the gear 122111 rotates and further drives the connecting member 1221 to integrally and coaxially rotate, and the connecting member 1221 further drives the cleaning member 1222 to rotate.

It should be appreciated that, for ease of understanding, the following description continues with the first embodiment of the auxiliary structure 1212 and the driven structure 12211 as an example.

Referring to fig. 6, 7 and 9, the cleaning member 1222 is detachably connected to the connecting member 1221.

It can be understood that, through the design that cleaning pieces 1222 are detachably connected with connecting pieces 1221, one connecting piece 1221 can correspond to a plurality of cleaning pieces 1222, so that when cleaning pieces 1222 are dirty or old, new cleaning pieces 1222 can be directly replaced on the original connecting piece 1221, thereby further saving resources, avoiding waste of resources, and achieving the effect of being more environment-friendly. In addition, the cleaning elements 1222 are detachably connected to the connecting elements 1221, so that one connecting element 1221 can correspond to a plurality of different cleaning elements 1222, thereby diversifying the use scene and functions of the electric toothbrush 1 and further improving the practicability of the electric toothbrush 1. Alternatively, the cleaning element 1222 and the connecting element 1221 can be removably connected by, but not limited to, magnetic attraction, clamping or adhesion.

Further, the connecting member 1221 includes a first limiting portion 12212, a second limiting portion 12221 is disposed on the cleaning member 1222 at a position corresponding to the first limiting portion 12212, the first limiting portion 12212 is matched with the second limiting portion 12221 in structure, and the first limiting portion 12212 rotates to drive the second limiting portion 12221 to rotate so that the connecting member 1221 and the cleaning member 1222 rotate coaxially.

It can be understood that, through the design of the first limiting portion 12212 and the second limiting portion 12221, which are matched in structure, the connecting rod 1211 can drive the first limiting portion 12212 to rotate, so as to further drive the second limiting portion 12221 to rotate, so that the connecting member 1221 and the cleaning member 1222 rotate coaxially, thereby ensuring that the cleaning member 1222 can rotate reliably to clean teeth.

Furthermore, one of the first limiting portion 12212 and the second limiting portion 12221 is a limiting protrusion 122121, the other is a positioning hole 122211 matching with the limiting protrusion 122121, and the connecting member 1221 and the cleaning member 1222 are matched to rotate coaxially through the positioning protrusion and the positioning hole 122211. It should be understood that the form and shape of the locating hole 122211 is not limited and may be either a through hole 1151 or a blind hole.

Specifically, in the embodiment of the present invention, the first position-limiting portion 12212 is a position-limiting protrusion 122121, and the second position-limiting portion 12221 is a positioning hole 122211. The position-limiting protrusion 122121 extends into the positioning hole 122211, and pushes the wall of the positioning hole 122211 when the position-limiting protrusion 122121 rotates, so that the cleaning elements 1222 rotate synchronously.

Please refer to fig. 10, which is another modified embodiment of the first position-limiting portion 12212 and the second position-limiting portion 12221. Specifically, the first limiting portion 12212 may also be a clamping hole 122122 formed in the connecting member 1221, the second limiting portion 12221 is a rotation following protrusion 122212 disposed on the cleaning member 1222 and corresponding to the clamping hole 122122, the rotation following protrusion 122212 is matched with the clamping hole 122122 in shape, the connecting member 1221 rotates, the clamping hole 122122 rotates, and the clamping hole 122122 rotates to drive the rotation following protrusion 122212 to rotate synchronously, so that the cleaning member 1222 and the connecting member 1221 rotate coaxially and synchronously.

Preferably, the section of the rotation following protrusion 122212 is non-circular, and the shape of the locking hole 122122 matches that of the rotation following protrusion 122212, so that the rotation of the locking hole 122122 can effectively drive the rotation following protrusion 122212 to rotate.

More preferably, the central axes of rotation of the cleaning element 1222 and the connecting element 1221 are central axes of rotation, and the rotation following protrusion 122212 and the locking hole 122122 are all arranged coaxially with the central axes of rotation. Therefore, the clamping hole 122122 and the rotating-following protrusion 122212 rotate concentrically, and the problem of loose connection caused by eccentric rotation is avoided.

Further, the rotation-following protrusion 122212 is engaged with the inner wall of the locking hole 122122, so as to further ensure the fastness of the connection between the rotation-following protrusion 122212 and the locking hole 122122.

With continued reference to fig. 6, the upper housing 123 includes a rear housing 1231 and a cover 1232. The rear housing 1231 defines an accommodating cavity 12311, the first magnetic element 1251, the connecting sleeve 1213, the limiting element 124 and at least a portion of the connecting rod 1211 are disposed in the accommodating cavity, a first opening 12312 is disposed at an end of the upper housing 123 away from the brush plate 122, and the driving element 112 sequentially passes through the first opening 12312 and the first magnetic element 1251 and then is connected to the connecting sleeve 1213.

Alternatively, the cover 1232 and the rear housing 1231 may be rotatably connected or fixedly connected. It should be understood that the fixed connection herein means that the cover 1232 and the rear housing 1231 are relatively fixed in position during use of the electric toothbrush 1.

When the cover 1232 is rotatably connected to the rear housing 1231, the shape of the rotating hole 12321 matches the shape of the first limiting portion 12212, and the first limiting portion 12212 rotates to drive the cover 1232 and the cleaning element 1222 to rotate coaxially.

When the cover 1232 is fixedly coupled to the rear housing 1231, the shape of the rotation hole 12321 is arc-shaped or annular. When the connecting member 1221 rotates, the first limiting portion 12212 rotates along the rotating hole 12321 and drives the cleaning member 1222 to rotate coaxially. Specifically, in the embodiment of the present invention, the rotation hole 12321 is a circular arc-shaped strip-shaped hole.

With reference to fig. 6 and fig. 9, further, a limiting groove 12322 having a shape matching that of the cleaning element 1222 is further formed in a surface of the cover 1232 away from the connecting element 1221, the cleaning element 1222 is embedded in the limiting groove 12322 and is in transmission connection with the connecting element 1221, and the connecting element 1221 rotates to drive the cleaning element 1222 to rotate coaxially in the limiting groove 12322. Preferably, the cleaning element 1222 is engaged with the inner wall of the limiting groove 12322, so as to further ensure the reliability of the connection between the cleaning element 1222 and the cover 1232.

Specifically, in this embodiment of the present invention, cleaning member 1222 is magnetically coupled to coupling member 1221.

Further, a third magnetic attraction piece 126 is further arranged between the cover 1232 and the connecting piece 1221, a fourth magnetic attraction piece 12222 is arranged on the cleaning piece 1222, and the cleaning piece 1222 and the connecting piece 1221 are magnetically attracted and detachably connected through the third magnetic attraction piece 126 and the fourth magnetic attraction piece 12222.

Furthermore, a notch 1261 with a shape identical to that of the rotation hole 12321 is formed on the third magnetic element 126, and the first position-limiting part 12212 passes through the notch 1261 and the rotation hole 12321 in sequence and then is connected to the cleaning element 1222.

Further, the rear housing 1231 is further provided with a connecting shaft 12314 from the rear housing 1231 toward the cover 1232, the connecting member 1221 and the third magnetic attraction member 126 are sequentially sleeved on the connecting shaft 12314, and the connecting member 1221 rotates with the connecting shaft 12314 as a rotation center shaft. Furthermore, a position of the cover 1232 corresponding to the connecting shaft 12314 is further provided with a limiting hole 12323 matching with the connecting shaft 12314 in shape, and the cover 1232 is partially sleeved on the connecting shaft 12314 through the limiting hole 12323, so as to limit the cover 1232 through the connecting shaft 12314.

With continued reference to fig. 9, the cleaning element 1222 includes a mounting box 12220 and a cleaning body 12225 for contacting and cleaning teeth, wherein one end of the mounting box 12220 is connected to the cleaning body.

Further, the mounting box 12220 includes a mounting cover 12223 and a rear cover 12224, opposite ends of the mounting cover 12223 are respectively connected to the rear cover 12224 and the cleaning body 12225, the fourth magnetic attraction 12222 is disposed between the cleaning body 12225 and the rear cover 12224, and the positioning hole 122211 is opened on the rear cover 12224. It should be understood that the mounting cap 12223 may be removably attached, fixedly attached, or integrally formed with the rear cap 12224, and the mounting cap 12223 may be removably attached, fixedly attached, or integrally formed with the cleaning body 12225.

Furthermore, a face of the rear cover 12224 away from the cleaning body 12225 is further provided with a guide protrusion 122241 matching with the shape of the limiting hole 12323, and when the cleaning element 1222 is connected to the connecting element 1221, the guide protrusion 122241 cooperates with the limiting hole 12323 to perform a guiding function, so as to facilitate installation of the cleaning element 1222. In the rotating process of the cleaning piece 1222, the guide protrusion 122241 is limited in the limiting hole 12323, so that the cleaning piece 1222 can rotate coaxially with the connecting piece 1221, and the cleaning effect of the cleaning piece 1222 is improved. It should be understood that the guide protrusion 122241 may be integrated with the follower protrusion 122212, and the position-limiting hole 12323 may be integrated with the position-limiting hole 122122.

Referring to fig. 11-13, optionally, cleaning bodies 12225 may be bristles 122251 (see fig. 11) or polishing heads 122252 (see fig. 12 and 13). It is understood that the brush head 12 is detachably coupled to the brush body 11 and the cleaning body 12225 may be designed as a brush head 122251 or a polishing head 122252, so that the brush body 11 can be matched with both the brush-shaped brush head 12 for cleaning teeth and the brush head 12 having a polishing function provided by the present invention, thereby enhancing the versatility of the brush head 12.

Referring to fig. 12 and 13, further, when the cleaning body 12225 is a polishing brush head 122252, the cleaning body 12225 includes a base 1222521 connected to the mounting cover 12223 and a polishing layer 1222522 disposed on the base 1222521, the polishing layer 1222522 is a surface layer contacting with the tooth surface, and the polishing layer 1222522 is made of a flexible material.

It will be appreciated that by providing the polishing layer 1222522 of flexible material with the polishing layer 1222522 in contact with the tooth surface, the polishing layer 1222522 is able to evenly friction polish the entire surface of the tooth, making it smoother and healthier.

Further, the material of the polishing layer 1222522 is a flexible material mixed with polishing components, and the material of the base 1222521 is the same as or different from the material of the polishing layer 1222522.

It will be appreciated that the polishing layer 1222522 is made of a flexible material mixed with polishing components so that the polishing layer 1222522 itself can provide a basic abrasive polishing of the teeth, thereby making the polishing process more convenient and faster. In addition, the design of base 1222521 of the same material as polishing layer 1222522 simplifies the manufacture of cleaning body 12225 and allows base 1222521 to continue to polish the teeth as polishing layer 1222522 wears or wears away, thereby improving the durability of head 12.

Further, the polishing layer 1222522 is made of a foamed sponge soft material and/or a foamed silica gel mixed with polishing powder. The polishing powder can be pearl powder, titanium dioxide, other polishing powder or a mixture of a plurality of polishing powders, etc.

Further, the polishing layer 1222522 is made of a foamed sponge soft material and/or a foamed silica gel mixed with fluoride, so as to protect teeth. Illustratively, the fluoride may be a combination of one or more of sodium fluoride, sodium monofluorophosphate, stannous fluoride, and other fluorides.

It can be understood that the fluoride is mixed in the polishing layer, so that the toothbrush head can also play a role of protecting teeth in the process of polishing the teeth, and the practicability of the toothbrush head is further improved.

Further, at least one storage groove 1222523 is formed in the polishing layer 1222522, the storage groove 1222523 is used for storing a polishing medium, and the polishing medium can be polishing toothpaste or polishing powder.

It can be understood that, by providing the storage groove 1222523 for storing polishing medium on the polishing layer 1222522, when the toothbrush head 12 polishes teeth with the polishing medium, the polishing medium can be at least partially stored in the storage groove 1222523 to improve the polishing effect of the toothbrush head 12, and prevent the storage medium from slipping off the polishing layer 1222522 and failing to polish the teeth during use. That is, the design of the storage groove 1222523 greatly enhances the polishing action and practicality of the toothbrush head 12.

Further, a plurality of storage grooves 1222523 having a uniform depth are spaced apart from each other on the polishing layer 1222522.

Further, polishing layer 1222522 may be substantially horn or cylindrical in shape.

It will be appreciated that when polishing layer 1222522 is substantially flared, polishing layer 1222522 is shaped to facilitate frictional polishing of non-flat areas such as crevices and roots of teeth. When the polishing layer 1222522 is substantially cylindrical, the polishing layer 1222522 is more convenient for rubbing and polishing the flat portion of the tooth in a large area, thereby effectively improving the uniformity and efficiency of polishing. Alternatively, the brush plate 122 may be rotated in the opposite direction (clockwise or counterclockwise) by an angle of 0 to 300. Specifically, in the embodiment of the present invention, the angular range of the rotation of the brush plate 122 in the opposite direction may be, but is not limited to, 0 to 15 °, 0 to 30 °, 0 to 60 °, 0 to 90 °, 0 to 100 °, 0 to 120 °, 0 to 150 °, 0 to 180 °, 0 to 200 °, 0 to 250 °, or 0 to 300 °.

Referring to fig. 14, a direction from the output shaft 1121 to the brush disc 122 is defined as an X direction, that is, a direction parallel to a central axis of the output shaft 1121, and a direction in which the brush disc 122 rotates when the brush disc 122 receives a force in the X direction is defined as an a direction. It is to be understood that the X direction may be a clockwise direction or a counterclockwise direction, and in particular, in the embodiment of the present invention, the X direction is a counterclockwise direction.

When the output shaft 1121 moves in the X direction, the output shaft 1121 drives the connection sleeve 1213 to move in the X direction, the connection sleeve 1213 drives the connection rod 1211 to further drive the auxiliary structure 1212 to move in the X direction, the auxiliary structure 1212 and the driven structure 12211 are matched to make the connection piece 1221 rotate in the a direction with the connection shaft 12314 as the center, and further the first limiting portion 12212 rotates in the a direction synchronously, the first limiting portion 12212 and the second limiting portion 12221 are matched to drive the rear cover 12224 of the cleaning piece 1222 to rotate in the a direction, and further the mounting cover 12223 and the cleaning body 12225 are driven to rotate coaxially with the connection piece 1221 in the limiting groove 12322 with the guiding protrusion 122241 as the rotation center shaft.

When the output shaft 1121 moves in the direction away from the X direction, the output shaft 1121 drives the connecting sleeve 1213 to move in the direction away from the X direction, the connecting sleeve 1213 drives the connecting rod 1211 to further drive the auxiliary structure 1212 to move in the direction away from the X direction, the auxiliary structure 1212 cooperates with the driven structure 12211 to make the connecting member 1221 rotate in the direction away from the a direction with the connecting shaft 12314 as the center, and further the first limiting portion 12212 rotates in the direction away from the a direction synchronously, the first limiting portion 12212 cooperates with the second limiting portion 12221 to drive the rear cover 12224 of the cleaning member 1222 to rotate in the direction away from the a direction, thereby driving the mounting cover 12223 and the cleaning body 12225 to rotate coaxially with the connecting member 1221 in the limiting groove 12322 with the guiding protrusion 122241 as the rotation center shaft.

In summary, the output shaft 1121 continuously reciprocates toward and away from the X direction, and the cleaning body 12225 is driven to rotate back and forth toward and away from the a direction, that is, the cleaning body 12225 rotates back and forth in the counterclockwise direction and the clockwise direction. The cleaning body 12225 continuously and repeatedly rubs the cleaning object teeth, etc., thereby performing a cleaning action and/or a polishing action.
